[0002] In recent years, a number of foam plastic manufacturing enterprises in China have gradually developed and grown. At present, excellent foam plastic manufacturing enterprises already have the ability to compete with world-class enterprises in some product and market fields, and the industry influence is gradually expanding. This project mainly uses linear low-density polyethylene as the matrix material, and adds cross-linking agent dicumyl peroxide and foaming agent azodicarbonamide. Among them, both the cross-linking agent and the foaming agent are variables, and the cross-linking and foaming of the mixture of the three are studied to make it cross-link at low temperature and foam at high temperature. Plastic master sheets (also known as plastic templates) are auxiliary tools widely used in the industrial production field. It is usually used to make models for injection-molded products to help engineers and designers carry out prototype design and inspection before manufacturing actual products.

[0003] During the secondary trimming process of plastic master sheets, the trimming device needs to trim off the unqualified extra parts on one side of the plastic master sheet to ensure the quality of subsequent processing. The existing secondary trimming technology for master sheets mostly uses a trimming knife fixedly installed on one side in the running direction of the plastic master sheet, and a limiting device is set on the other side to prevent the plastic master sheet from shifting. However, due to the presence of the trimming knife, the blade contacts the master sheet during cutting, which easily touches the master sheet, resulting in uneven edges of the plastic master sheet. Moreover, the trimming blade is usually fixed by bolts, which is inconvenient for installation and disassembly, thus affecting the production efficiency of the trimming production line and increasing production costs.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-5 As shown, a multi-channel trimming device for extrusion foamed material master sheets includes a connecting rod 1. Mounting plates 2 are provided at both ends of the connecting rod 1. The connecting rod 1 is mounted on the conveying equipment of the master sheet by using the mounting plates 2. It also includes: a first connecting sleeve 3 and a second connecting sleeve 4 arranged outside the connecting rod 1. A limiting component 5 for limiting the master sheet is arranged outside the first connecting sleeve 3. The upper part of the master sheet is limited by using the limiting component 5. An auxiliary component 6 for improving the limiting effect on the master sheet is arranged outside the limiting component 5. The limiting effect on the master sheet is improved by the combined action of the auxiliary component 6 and the limiting component 5; a blade 9 for trimming the master sheet is arranged outside the second connecting sleeve 4. A limiting sleeve 8 is arranged outside the blade 9. A mounting component 7 for mounting and fixing the blade 9 is arranged outside the limiting sleeve 8. The blade 9 is mounted and fixed on the second connecting sleeve 4 by using the mounting component 7 and the limiting sleeve 8. At the same time, the mounting component 7 also facilitates the disassembly, replacement and maintenance of the blade 9.

[0023] The limiting component 5 includes a fixing frame 501 arranged outside the first connecting sleeve 3. The fixing frame 501 is welded to the bottom of the first connecting sleeve 3. A spring 502 and a damping rod 503 are arranged outside the fixing frame 501. The damping rod 503 is mounted outside the fixing frame 501, and a connecting plate is arranged outside the damping rod 503. The bottom of the spring 502 is welded to the connecting rod, and the top is welded to the fixing frame 501. A moving wheel 504 is arranged outside the damping rod 503. The moving wheel 504 is mounted at the bottom of the damping rod 503. The spring 502 and the damping rod 503 apply pressure to the moving wheel 504, so that the moving wheel 504 rolls on the upper part of the master sheet to limit the master sheet. When the surface of the master sheet is uneven, the moving wheel 504 drives the spring 502 and the damping rod 503 to contract, and the height of the moving wheel 504 can be automatically adjusted.

[0024] The auxiliary component 6 includes a connecting block 601 arranged outside the damping rod 503. A pressure rod 602 is arranged outside the connecting block 601, and a connecting rod 603 is arranged between the pressure rod 602 and the damping rod 503. The pressure rod 602 is arranged on both sides of the moving wheel 504 to press the mother plate, improving the limiting effect on the mother plate. When the pressure rod 602 encounters an uneven surface, the pressure rod 602 rotates outside the connecting block 601, and at the same time drives the connecting rod 603 to rotate between the connecting block 601 and the pressure rod 602, performing a limiting process on the pressure rod 602 and improving the limiting effect on the mother plate.

[0025] The installation component 7 includes a housing 701 arranged outside the second connecting sleeve 4. The housing 701 is fixedly installed on the second connecting sleeve 4. A bidirectional screw 702 is arranged inside the housing 701. The bidirectional screw 702 is rotatably installed in the housing 701. Two symmetrical screw sleeves 703 are arranged outside the bidirectional screw 702. A clamping rod 705 and a limiting rod 704 are respectively arranged outside the two screw sleeves 703. Both the clamping rod 705 and the limiting rod 704 are rotatably connected to the screw sleeve 703; a limiting sleeve 8 is arranged outside the housing 701, and a through groove for the blade 9 to pass through is arranged inside. The limiting sleeve 8 is welded to the lower part of the housing 701, and the blade 9 passes through the limiting sleeve 8 and enters the inside of the housing 701.

[0026] A handwheel 10 is fixedly connected to the outside of the bidirectional screw 702, which facilitates the rotation of the bidirectional screw 702 by using the handwheel 10.

[0027] Working principle: According to the need of trimming, the first connecting sleeve 3 and the second connecting sleeve 4 are adjusted to appropriate positions on the connecting rod 1. When installing the blade 9, the blade 9 is inserted into the limiting sleeve 8, and then the two-way screw rod 702 is rotated by the hand wheel 10. The two-way screw rod 702 drives the two screw sleeves 703 on both sides to approach each other. The two screw sleeves 703 respectively drive the clamping rod 705 and the limiting rod 704 on their outer sides to move. The clamping rod 705 first clamps into the preset clamping holes on the blade 9, and then the limiting rod 704 clamps onto the outer side of the clamping rod 705 to limit the clamping rod 705, thereby improving the fixing effect on the blade 9. The blade 9 is used to trim the mother sheet. The spring 502 and the damping rod 503 apply pressure to the moving wheel 504, causing the moving wheel 504 to roll on the upper part of the mother sheet to limit the mother sheet. When the surface of the mother sheet is uneven, the moving wheel 504 drives the spring 502 and the damping rod 503 to contract, and the height of the moving wheel 504 can be automatically adjusted. The pressing rods 602 are arranged on both sides of the moving wheel 504 to press the mother sheet, improving the limiting effect on the mother sheet. When the pressing rods 602 encounter an uneven surface, the pressing rods 602 rotate outside the connecting block 601, and at the same time drive the connecting rod 603 to rotate between the connecting block 601 and the pressing rod 602 to limit the pressing rod 602, improving the limiting effect on the mother sheet. When the blade needs to be replaced, the two-way screw rod 702 is rotated in the reverse direction to expand the clamping rod 705 and the limiting rod 704, so that the blade 9 can be taken out of the limiting sleeve 8 for replacement.
