Technical Field

[0001] This utility model relates to the field of thermoplastic processing technology, specifically to a thermoplastic elastomer processing device for automotive interiors. Background Technology

[0002] Thermoplastic elastomers (TPE / TPR), also known as synthetic rubber or synthetic materials, possess the excellent properties of traditional cross-linked vulcanized rubber, such as high elasticity, aging resistance, and oil resistance, while also having the advantages of ordinary plastics, such as easy processing and a wide range of processing methods. They can be produced by injection molding, extrusion, blow molding, and other processing methods, and the sprue edges can be directly reused 100% after being crushed.

[0003] However, current thermoplastic elastomer processing equipment requires cutting thermoplastic parts. During the cutting process, thermoplastic parts are prone to folding, resulting in poor cutting effect and affecting the processing effect. Therefore, we propose a thermoplastic elastomer processing equipment for automotive interiors. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution: a thermoplastic elastomer processing device for automotive interiors, including a support frame 1, a blower mechanism 2 provided on the side of the support frame 1, a feeding mechanism 3 provided on the surface of the support frame 1, a fixing mechanism 4 provided on the top of the support frame 1, and a cutting mechanism 5 provided on the surface of the support frame 1.

[0022] Specifically, the blower mechanism 2 includes an exhaust pump 201, with an exhaust box 202 installed at the output end of the exhaust pump 201. Multiple air outlets 203 are evenly spaced on the surface of the exhaust box 202. The exhaust box 202 is mounted on the inner wall of the support frame 1, and the exhaust pump 201 is mounted on the side surface of the support frame 1. The feeding mechanism 3 includes a first motor 301 and a second motor 303. A first rotating shaft 302 is installed at the output end of the first motor 301, and a first threaded rod 304 is installed at the output end of the second motor 303. A first threaded cylinder 307 is threadedly connected to the surface of the first threaded rod 304, and a first slider 306 is connected to the surface of the first threaded cylinder 307. One end of the first slider 306 is connected to a moving plate 308, and a second rotating shaft 309 is installed on the surface of the moving plate 308. One end of the roller is slidably connected to the first slide rail 305. The first motor 301, the second motor 303, and the first slide rail 305 are all mounted on the surface of the support frame 1. By inserting one end of the roller shaft with the thermoplastic part wound on it into the surface of the first rotating shaft 302, the second motor 303 drives the first threaded rod 304 to rotate, causing the first threaded cylinder 307 to move. In conjunction with the first slide rail 305 and the first slider 306, the moving plate 308 moves, thereby causing the second rotating shaft 309 to move. The second rotating shaft 309 is inserted into the roller shaft. The first motor 301 drives the first rotating shaft 302 to rotate, and in conjunction with the rotation of the second rotating shaft 309, the roller shaft rotates, releasing the thermoplastic part from the surface of the roller shaft. Then, the exhaust pump 201, in conjunction with the air box 202 and the air outlet 203, blows air, blowing the thermoplastic part toward the cutting blade 507.

[0023] Specifically, the fixing mechanism 4 includes a third motor 401 and a moving frame 405. The output end of the third motor 401 is equipped with a third rotating shaft 402, and a gear 403 is installed at one end of the third rotating shaft 402. A rack 404 is slidably connected inside the moving frame 405. The rack 404 and the gear 403 are meshed. A fixing plate 406 is installed at one end of the rack 404. There are two fixing mechanisms 4, which are symmetrically installed on the surface of the support frame 1. The third motor 401 is installed on the top of the support frame 1, and the moving frame 405 is located on the top of the support frame 1. The third motor 401 drives the third rotating shaft 402 to drive the gear 403 to rotate. In conjunction with the moving frame 405, the rack 404 moves up and down, causing the fixing plate 406 to move and contact the thermoplastic part. The support frame 1 then fixes and clamps the thermoplastic part to prevent it from moving during cutting.

[0024] Specifically, the cutting mechanism 5 includes a fourth motor 501, a second slide rail 504, and a slide groove 506. A second threaded rod 502 is installed at the output end of the fourth motor 501. A second threaded cylinder 503 is threadedly connected to the surface of the second threaded rod 502. A second slider 505 is connected to the surface of the second threaded cylinder 503. A cutting blade 507 is connected to one end of the second slider 505. Both the fourth motor 501 and the second slide rail 504 are provided with the surface of the support frame 1. The slide groove 506 is opened on the surface of the support frame 1. The cutting blade 507 extends to the surface of the support frame 1 through the slide groove 506. The fourth motor 501 drives the second threaded rod 502 to rotate, causing the second threaded cylinder 503 to move. In conjunction with the second slide rail 504, the second slider 505, and the slide groove 506, the cutting blade 507 moves and moves with the slide groove 506 to cut the thermoplastic part.

[0025] All electrical devices in this invention are powered by an external power source;

[0026] Working principle: By inserting one end of the roller shaft with the thermoplastic part wound on it into the surface of the first rotating shaft 302, the second motor 303 drives the first threaded rod 304 to rotate, causing the first threaded cylinder 307 to move. This, in conjunction with the first slide rail 305 and the first slider 306, moves the moving plate 308, thereby moving the second rotating shaft 309. The second rotating shaft 309 is then inserted into the roller shaft. The first motor 301 drives the first rotating shaft 302 to rotate, and in conjunction with the rotation of the second rotating shaft 309, the roller shaft rotates, discharging the thermoplastic part from its surface. Then, the exhaust pump 201, in conjunction with the air box 202 and the air outlet 203, blows air onto the thermoplastic part. The part is blown towards the cutting blade 507, and then the third motor 401 drives the third rotating shaft 402 to drive the gear 403 to rotate. In conjunction with the moving frame 405, the rack 404 moves up and down, causing the fixing plate 406 to move and contact the thermoplastic part. The fixing plate 406 is then fixed and clamped with the support frame 1 to prevent the thermoplastic part from moving during cutting. The fourth motor 501 drives the second threaded rod 502 to rotate, causing the second threaded cylinder 503 to move. In conjunction with the second slide rail 504, the second slider 505, and the slide groove 506, the cutting blade 507 moves and moves with the slide groove 506 to cut the thermoplastic part.
