Description

Technical Field

[0001] The utility model belongs to the technical field of sealing and cutting machines, in particular to a heat shrink film corner sealing and cutting machine. Background Art

[0002] After heat shrink film is packaged, the excess edges often need to be trimmed. A heat shrink film corner sealer is a piece of equipment used in the packaging industry to seal and trim the edges of heat shrink film. This machine is commonly used to package a variety of products, such as food, beverages, and cosmetics. It effectively seals and shrinks the film, making the product neater and safer.

[0003] A Chinese patent with publication number "CN216685147U" discloses a film cutting device for a fully automatic sealing and cutting machine, which includes a frame, a downward-facing cylinder mounted on the top of the frame, a linkage plate provided at the telescopic end of the cylinder, and a rotating film cutting mechanism provided in the middle of the lower surface of the linkage plate. The rotating film cutting mechanism includes a motor, a rotating shaft, two fixed seats, two hot-cutting dies, and two upper blades. The utility model provides a rotating film cutting mechanism, which includes a motor, a rotating shaft, two fixed seats, two hot-cutting dies, and two upper blades. The motor drives the rotating shaft to rotate, causing the two upper blades to rotate with each other for a cycle, thereby avoiding long-term continuous operation of the blades and ensuring the service life of the blades. The two upper blades work alternately, avoiding the need to shut down the machine for maintenance when a blade is damaged during operation. Only the position of the other blade needs to be adjusted to ensure the normal operation of the film cutting operation. The utility model has a simple structure and is easy to operate.

[0004] During use, the above device can assist in adjusting the cutting blade and can replace the cutting blade without stopping the equipment. However, the cutting blade is fixed on the rotating shaft, which is obviously not convenient to remove quickly when replacing the cutting blade. It can be seen that the overall disassembly and assembly of the cutting blade is relatively cumbersome and inconvenient. Although the overall device can perform uninterrupted cutting processing without stopping for replacement, it is obvious that the disassembly and assembly of the cutting blade is still inconvenient. The overall inspection and maintenance cost and time-consuming during use are relatively high, so it needs to be improved. Utility Model Content

[0011] As an optimal technical solution, adjustment plates are fixedly installed on both sides of the card block, and the outer ends of the adjustment plates pass through the reserved slots. The adjustment plates are provided so that during use, the card block can be pressed to cause the limit spring to contract, and the card block on the limit spring is separated from the card slot, making it convenient to quickly disassemble and assemble the cutting knife.

The wear-resistant gasket can improve the overall friction resistance of the sliding block 62, the sliding rod 353 and the sliding block 73, and can improve the overall stability of the device.

[0036] Principle and advantages of use: By setting the cutting mechanism 3, during use of the device, the driving motor 32 can be started to drive the mounting roller 33 to rotate, and the rotation of the mounting roller 33 can assist in flipping the cutting knife 34. When the top cutting knife 34 is worn and needs to be replaced, the bottom cutting knife 34 can be quickly adjusted to be replaced upward, so that the device can perform uninterrupted continuous cutting, which can improve the overall production and processing efficiency of the device. At the same time, a pressure component 6 is provided, which can push the pressing plate 63 inside the concave seat 4 downward by moving the telescopic cylinder 5. The cutting groove 64 at the bottom of the pressing plate 63 cooperates with the cutting knife 34 to quickly perform disassembly and cutting processing, which can improve the overall disassembly and cutting processing stability and cutting processing efficiency of the device.

[0037] By providing the guide mechanism 7, during the use of the device, during the cutting process, the guide roller 75 plays an auxiliary lifting role, and can contact the heat shrink film to be cut through the guide roller 75. During this period, the pressure of the heat shrink film acts on the guide roller 75 of the mounting frame 74. The guide roller 75 and the sliding block 73 cooperate to resist the telescopic spring 72, and the telescopic spring 72 can assist in buffering the sliding block 73. The mutual fit between the pressure roller 66 and the guide roller 75 can play a good buffering role, so that only the cutting blade 34 has sharp corners during cutting, avoiding the external sharp corners from scratching the heat shrink film, and improving the overall cutting stability of the heat shrink film.

[0038] The clamping assembly 355 is provided so that when the cutting blade 34 needs to be removed and assembled during use, the adjusting plate 357 at the bottom is pressed upward, and the adjusting plate 357 is pressed against the limit spring 354 to contract. The limit spring 354 contracts, causing the clamping block 355 to move inward, and the clamping block 355 moves inward and out of the clamping slot 356. At this time, the inner limit structure of the sliding rod 353 and the mounting rail 351 is lost. At this time, the sliding rod 353 can be quickly withdrawn, and the cutting blade 34 can be replaced by withdrawing the sliding rod 353. At this time, the sliding rod 353 with the new cutting blade 34 is reinserted into the mounting rail 351, the adjusting plate 357 is released, and the limit spring 354 is used to return the clamping block 355 to the inner limit slot 356. The cutting blade 34 can be installed on both sides of the mounting roller 33 by the clamping block 355 and the clamping slot 356 again.
