Description

Technical Field

[0001] The invention relates to the technical field of biomaterial production equipment, in particular to a coating equipment for producing periodontal regeneration membrane. Background Art

[0002] As a key material for periodontal tissue regeneration, the coating process in the production process of periodontal regeneration membrane is crucial to the quality and performance of the product.

[0003] When the existing periodontal regeneration membrane coating equipment is working, it is necessary to evenly coat the collagen solution on the polyurethane membrane. However, the existing coating equipment cannot continuously coat the membrane. Often, after coating a membrane, it is necessary to manually load the material and then coat it. The coating efficiency is relatively low, and manual unloading is also troublesome. In addition, the membrane needs to be cleaned of dust before coating. The manual cleaning method is inefficient, and the impurities and dust after cleaning are not easy to collect uniformly. In addition, after the coating is completed, there is often excess glue remaining on the surface of the membrane. If the excess glue is not removed cleanly, not only the subsequent drying time will be prolonged, but also the glue will be wasted. In this regard, we propose a coating equipment for periodontal regeneration membrane production to solve the above problems. Summary of the invention

The motor 3 82 drives the driving rod 81 to rotate. Two cams 83 are fixed to the outer surface of the driving rod 81. A baffle 84 is slidably connected to the inner surface of the through slot 7. When the baffle 84 is at the highest point, it can block the diaphragm 2. When it drops to the lowest point, it just drops by the height of a diaphragm 2, so that the diaphragm 2 can be discharged.

Rubber blocks 102 are fixed at the bottom ends of the two connecting rods 101. The bottoms of the two rubber blocks 102 are in contact and squeezed with the top of the diaphragm 2. After the rubber blocks 102 squeeze the diaphragm 2 downward, the friction between the rubber blocks 102 and the diaphragm 2 can be increased, and when the diaphragm 2 moves to the right, it is convenient to discharge the material.

[0032] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

When the uppermost diaphragm 2 rises to be flush with the top of the mold box 1, the infrared transmitter 6 emits infrared rays which are received by the infrared receiver. Once the uppermost diaphragm 2 blocks the infrared rays, the infrared sensor sends a signal command to stop the motor 2 42, and the cylinder 38 is further started, so that the cylinder 38 drives the coating roller 310 to move downward into the glue tank 11 for gluing, and the motor 1 36 is further started, so that the motor 1 36 drives the screw rod 34 to rotate, and the screw rod 34 drives the U-shaped plate 37 to move to the right, and when the U-shaped plate 37 moves to the right, it drives the coating roller 310 to apply glue on the surface of the diaphragm 2, and the scraper 311 moves to the right.

At this time, the baffle 84 moves down to the height of the diaphragm 2, and further start the cylinder 38 to let the coating roller 310 squeeze the diaphragm 2. At the same time, the U-shaped frame 39 drives the connecting rod 101 and the rubber block 102 to squeeze the diaphragm 2 downward. At this time, start the motor 36 to make the motor 36 drive the U-shaped plate 37, the coating roller 310 and the rubber block 102 to move to the right, and at the same time drive the coated diaphragm 2 to be discharged, so that it enters the drying equipment for drying.
