Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic materials technology, specifically to a cutting device for PP plastic packaging materials. Background Technology
[0002] PP plastic packaging materials refer to packaging materials made primarily of polypropylene, or PP for short. Polypropylene is a thermoplastic with good chemical stability, a high melting point, excellent tensile strength, and corrosion resistance, making it widely used in the packaging industry.
[0003] Currently, when processing PP plastic materials used for packaging, it is usually necessary to trim or cut the material. Due to different packaging requirements, the width of the PP material used varies, requiring trimming devices. However, existing trimming devices are generally manual or mechanical. These cutting methods are not very precise, and they directly contact the cutting blade with the plastic, which can easily lead to greater friction between the blade and the plastic surface, and can also easily cause uneven and rough edges.

[0022] Please see Figure 1-4 As shown, a PP plastic packaging material cutting device includes an operating table 1, and also includes: support legs 2 fixed to the four corners of the bottom of the operating table 1, a support plate 3 fixedly connected to the rear side of the top of the operating table 1, the support plate 3 facilitates the support of the extension plate 4, and the extension plate 4 facilitates the support of the fixed plate 5 and the driving component 6, the top of the support plate 3 is fixedly connected to the extension plate 4, the top of the extension plate 4 is fixedly connected to the fixed plate 5, and a driving component 6 is provided on one side of the fixed plate 5, the driving component 6 including a first motor 601;
[0023] The connecting rod 7, located inside the extension plate 4, can lower the cutting blade 17 by cooperating with the limiting shell 8. The top of the connecting rod 7 is fixedly connected to the limiting shell 8, which is used in conjunction with the driving component 6. The top of the operating table 1 is equipped with driving take-up rollers 9 on both sides. The bottom of the operating table 1 is fixedly connected to both the front and rear sides of one side. The fixed plate 10 is fixedly connected to one side of the fixed plate 10. The cutting edge component 11 includes a second motor 1101 and a limiting groove 1102. The top of the operating table 1 is fixedly connected to a support platform 12. The top of the support platform 12 is provided with a cutting groove 13.
[0024] Limiting plates 14 are fixedly connected to both the front and rear sides of the support platform 12. An auxiliary roller 15 is rotatably connected between the opposite sides of the two limiting plates 14. The limiting plates 14 facilitate support for the auxiliary roller 15, which in turn provides auxiliary support for both sides of the plastic part during cutting. A guide rail 16 is fixedly connected to the bottom of the connecting rod 7. The guide rail 16 facilitates the installation and removal of the cutting blade 17. The cutting blade 17 is inserted into the bottom of the guide rail 16. Support rods 18 are fixedly connected to the four corners of the bottom of the extension plate 4. The support rods 18 facilitate the installation and fixation of the first heating device 19. The 9-drive mechanism works in conjunction with the first heat-conducting copper pipe 20 to conduct heat, thereby heating the cutting blade 17 to facilitate cutting plastic materials. The bottom of the support rod 18 is fixedly connected to the first heating device 19, which contains the first heat-conducting copper pipe 20. Slide rods 21 are provided on both the front and rear sides of the inner cavity of the limiting shell 8. The sliding rods 21 can limit the vertical movement of the limiting shell 8. The bottom of the sliding rods 21 is fixedly connected to the extension plate 4. A spring 22 for resetting is fixedly connected between the bottom of the limiting shell 8 and the top of the extension plate 4. The spring 22 can assist in resetting the limiting shell 8 and simultaneously raise the connecting rod 7.
[0025] The first motor 601 is fixed to one side of the fixed plate 5. The output end of the first motor 601 passes through to one side of the fixed plate 5 and is fixedly connected to the turntable 602. A retaining rod 603 is fixedly connected to one side of the turntable 602. Turning on the first motor 601 can make the turntable 602 rotate. At this time, the retaining rod 603 will rotate in a ring inside the limiting shell 8. When the retaining rod 603 rotates to the lower position, the limiting shell 8 will squeeze the spring 22 and limit the movement on the surface of the slide rod 21. It will also drive the connecting rod 7 and the guide rail 16 to descend. After the cutting blade 17 inside the guide rail 16 is preheated, it descends and cooperates with the cutting groove 13 to cut the plastic material. The surface of the retaining rod 603 passes through the interior of the limiting shell 8.
[0026] The second motor 1101 is fixed to one side of the fixing plate 10. The limiting groove 1102 is opened inside one side of the operating table 1. The output end of the second motor 1101 passes through to one side of the fixing plate 10 and is fixedly connected to a bidirectional lead screw 1103. One side of the bidirectional lead screw 1103 is rotatably connected to the fixing plate 10. Threaded sleeves 1104 are fitted on both the front and rear sides of the surface of the bidirectional lead screw 1103. A sliding block 1105 is fixedly connected to the top of the threaded sleeve 1104, and an extension frame 1106 is fixedly connected to the top of the sliding block 1105. Turning on the second motor 1101 causes the bidirectional lead screw 1103 to rotate relative to each other. As the bidirectional lead screw 1103 rotates, the two threaded sleeves 1104 can rotate. The two sliding blocks 1105 are moved, which in turn drives the extension frame 1106 to move in conjunction with the second blade 1107. The second heating device 1108 heats the material, causing the second heat-conducting copper tube 1109 to conduct heat and generate temperature on the cutting surface of the second blade 1107. Heating the blade reduces friction between the blade and the material surface, making the cutting smoother, reducing the tensile force on the material, and avoiding irregular cutting marks. The second blade 1107 is fixedly connected to one side of the extension frame 1106, and the second heating device 1108 is fixedly connected to one side of the second blade 1107. The second heat-conducting copper tube 1109 is installed inside the second heating device 1108.
[0027] Working principle: First, the user can put the plastic material to be processed onto the two drive take-up rollers 9 and then convey it. During the conveying process, if it is necessary to adjust the cutting edge width, the second motor 1101 can be turned on to make the bidirectional lead screw 1103 rotate relative to each other. As the bidirectional lead screw 1103 rotates, the two threaded sleeves 1104 can drive the two sliding blocks 1105 to move. When the sliding blocks 1105 move, they will drive the extension frame 1106 to move in conjunction with the second blade 1107. The second heating device 1108 heats the second heat-conducting copper pipe 1109 to conduct heat, so that the cutting surface of the second blade 1107 generates temperature. Heating the cutting tool reduces friction between the tool and the material surface, making the cutting smoother, reducing the tensile force on the material, and avoiding irregular cutting marks. After the cutting is completed, the first motor 601 can be turned on to rotate the turntable 602. At this time, the retaining rod 603 will rotate in a ring inside the limiting shell 8. When the retaining rod 603 rotates to the lower position, the limiting shell 8 will squeeze the spring 22 and move to the limit on the surface of the slide rod 21, and drive the connecting rod 7 and the guide rail 16 to descend. After the cutting blade 17 inside the guide rail 16 is preheated, it descends and cooperates with the cutting groove 13 to cut the plastic material.
