Factors of tablet forming Tablet press is another element of sheet forming. The quality of tablets is directly affected by the performance of the specifications, the mechanical condition of the equipment in operation and some important parts of the tablet press, such as the wear of the die. (1) from the size of the model, rotary tablet press than the impact of the tablet press pressure, and uniform, sliver phenomenon is easy to control. Because the feeding hopper is fixed, the machine vibration is small, the particle stratification phenomenon is less, the sheet weight is accurate and stable. But the rotary tablet press has a variety of single-track and dual-track models. In the production of sliver, loose sliver, sheet weight difference, to consider the double track press speed, particle compression time is shorter than the monorail type, easy to produce sliver, loose sliver phenomenon. At this time should pay attention to the appropriate increase pressure, slow down the speed. I

The use of stretch film vacuum packing machine Recently, continuous vacuum packaging machine has gradually entered our packaging field of vision. Because of its high degree of automation, it can greatly improve the production efficiency of enterprises, and people begin to use this equipment in large numbers. The equipment is famous for its high efficiency, fast and high output, and began to occupy a place in the packaging market. However, customers in a large number of use at the same time, but also to pay more attention to the operation of continuous vacuum packaging machine need to pay attention to matters, in order to prevent illegal operation. 1. When the continuous vacuum sealing machine works continuously, or the vacuum pump works continuously for more than half an hour, the operator needs to connect the cooling water source to ensure the quality of the vacuum sealing and the safe operation of the equipment. 2. When the equipment is stopped, the vacuum pump should be turned o

Blister packaging machine mesh problem In the hot sealing process of flat type aluminum foam cover packaging, PVC and aluminum foil are made of parallel flat heat sealing plate and mesh plate in the same plane under certain temperature and pressure to complete the hot sealing. The contact between the heat sealing plate and the mesh plate is planar contact, and the pressure required is relatively large. The following problems should be solved when the heat sealing mesh is not clear, the depth of mesh is different, and the running of PVC belt causes crush-bubbles during thermal sealing: (1) Whether the aluminum foil is a qualified product, and whether the thermal bonding surface is coated with the required thermal sol; (2) whether the temperature of the heating device is too high or too low; (3) PVC belt or aluminum foil running whether there is abnormal resistance; (4) Whether the heat sealing mold is qualified, whether the surface is smooth and smooth, and whether the

Stretch film vacuum packing machine using steps Stretch film vacuum packing machine operation procedures: 1. Install the film: when the film frame is on the work surface, open the upper frame and pull the film slightly over the right edge of the frame, and press the upper frame to clamp the film. 2. Lift: Check whether the "box selection" switch K3 is in the "continuous" position, and press the "lift" switch. 3. So the membrane frame can be automatically continuous up to close to the switch control of the fixed point automatic stop, before the lifting frame must be prior to the film reel loose, so as to avoid adhesion between the membrane to stop the rise of the membrane frame. 4. Put the tray with packaged goods in the vacuum room of the working vacuum packing machine, and use tools instead of pushing it directly by hand, in case of electrical failure and personal injury. 5. Press the "automatic packaging" switch, film heating, heat preservation and suction three pro

Blister packaging machine forming is not good how to do? If there is a whole row or a regular column or more columns of bubble bubble forming, forming is not full, it needs to be checked from the following aspects. (1) Whether the temperature of the heating plate does not reach the set value before molding, check whether the temperature setting is not enough or the heating temperature is too high, resulting in PVC stretching thin and forming air leakage; (2) before forming, the heating plate is not parallel to the forming mold or the distance between the heating plate and the forming mold exceeds the distance of the plate bubble cap; (3) The heated PVC runs with the lower mold, resulting in the cold shrinkage of PVC; (4) forming the upper and lower heating plates are not parallel to each other, resulting in uneven heating at one end. (5) whether the compressed air formed by positive pressure is clean and dry, whether the pressure is lower than 0.4Mpa during operation,

Tablet press operation (1) The standard operating procedure for pressing tablet equipment is to install the middle die, the upper punching, the lower punching, the powder scraper, the feed hopper, the flow tray, the exhaust pipe of the dust removal machine in turn, and to install and connect the tablet powder remover. The installation of the special shape pressing die: mount the punching die, and position the middle die with the punching die. And according to the number of the mold into the number. Other procedures are the same as ordinary tablet pressing. And other production equipment ready. (2) rotate the handwheel by hand, make the turntable rotate 1-2 times, after confirming that there is no abnormality, close the glass door, put the right amount of particles into the hopper, manually test the pressure, adjust the tablet weight, pressure, measure the tablet weight and the difference of the tablet weight, disassembling time, hardness, confirm that it meets the requirements and be

The device that the tablet press should have 1. The fluidity of fine powder in the device of oscillating feeding powder or forced feeding powder is always not as good as that of particles. It is easy to appear holes in the feeder or flow fast or slow, resulting in a large difference in sheet weight, and the device can make the powder evenly flow into the die hole. 2. Because there is more air in the powder than in the particle, it is easy to produce top crack when pressing the tablet. The solution is to reduce the speed of the tablet, the second is the second compression, that is, the first time for the initial compression, the second time for the final compression into tablets. Due to the increased compression time, it is beneficial to discharge the air in the powder, reduce the phenomenon of fragmentation, and increase the hardness of the tablet. 3. Good sealing and dust removal device because of the powder has flying, the powder directly press tablet, will produce more d

Capsule machine loading volume adjustment and production The volume adjustment and production are as follows (pharmaceutical) : (1) Move the filling part to a very low position, then loosen the lower nut of the hand wheel on the upper part of the filling, and adjust the hand wheel. The smaller the amount shown in the window, the lighter the loading quantity. The first set of filling rods should be adjusted to the under-plane of protruding metering plate by eye observation, and then the nuts should be fixed. The sixth group is adjusted to the upper plane of the metering plate 1 mm lower, the fourth group is 1-2 mm lower than the filling rod of the fifth group, and so on... . If the weight is too light (Group 1 and Group 6 will not be adjusted), the other four groups can be fine-tuned. (2) Enter the manual page and add the capsule and powder into the capsule bucket and powder bucket respectively. (3) Click the capsule switch and the vacuum pump, click the button of the electr

The difference between stretch film vacuum packing machine and ordinary vacuum packing machine Stretch film vacuum packing machine is a vacuum packing machine, but it is not the same as the ordinary two-chamber vacuum packing machine. There is a fundamental difference in structure between the two types of equipment. Many customers do not know the difference between the two at the time of purchase. The following is a brief description of the difference between stretch film vacuum packaging machine and other food vacuum packaging machine. 1. Different packaging materials: like double-chamber vacuum packing machine or extraction-type vacuum packing machine, the packaging material is vacuum bag, while the packing material of stretch film vacuum packing machine is PE film and roll film material. This is an easy point to distinguish after packaging. 2. Different working principles: ordinary vacuum packing machine is bonded together by sealing, while stretch film vacuum packing machi
