However, with the increasing use of plastic sheets, the demand for their cutting and processing is also growing.

DETAILED DESCRIPTION

[0037] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

A first drive motor 304 is provided at one end of the bottom of the mounting block 303, and a cutting knife 305 is fixedly connected to the output end of the first drive motor 304. A second drive motor 306 is provided at the top of the mounting block 303, and a grinding block 307 is fixedly connected to one end of the output shaft of the second drive motor 306; it also includes an adsorption mechanism 4, which is provided with two groups and is respectively arranged at both ends of the cutting and grinding mechanism 3. The adsorption mechanism 4 includes a vacuum pump 401, a second cylinder 402 and a suction cup 405. The two vacuum pumps 401 are respectively fixedly connected to the two ends of the top of the cutting box 1, and the two ends of the top of the inner wall of the cutting box 1 are respectively fixedly connected to the second cylinder 402. The output end of the second cylinder 402 is fixedly connected to the connecting plate 403, and two suction nozzles 404 are respectively fixedly connected to the two ends of the connecting plate 403, and the bottom of the suction nozzle 404 is connected to the suction cup 405, and the top of the suction nozzle 404 is connected to the input end of the vacuum pump 401;

[0039] In the present embodiment, since many burrs will be generated in the cutting process of the plastic sheet, these burrs will not only affect the appearance of the plastic product, but also make subsequent processing more difficult or even impossible, such as uneven painting, loose bonding and other problems. Therefore, the design of the cutting and grinding mechanism 3 can not only cut the plastic sheet, but also remove the burrs generated in the cutting process in time. When working, the plastic sheet is first placed on the conveying roller 2. Under the conveying of the conveying roller 2, the plastic sheet will enter the cutting box 1 through the feed port 101. In order to avoid the cutting knife 305 from damaging the conveying roller 2 during the cutting process, the plastic sheet needs to be transported to the support plate 103 for cutting. After the plastic sheet enters the cutting box 1, The two second cylinders 402 are opened, and the connecting plate 403 moves downward under the drive of the second cylinders 402, thereby driving the suction nozzle 404 to move downward. When the suction cup 405 at the bottom of the suction nozzle 404 contacts the plastic sheet, the vacuum pump 401 is turned on at this time. Under the action of the vacuum pump 401, a vacuum is generated inside the suction cup 405, thereby firmly adsorbing the plastic sheet. At this time, the second cylinder 402 is turned on to drive the plastic sheet to move upward. When the plastic sheet moves above the support plate 103, the electric push rod 105 is turned on. Under the drive of the electric push rod 105, the support plate 103 moves. When the opposite ends of the two support plates 103 are spliced ​​together, the plastic sheet is driven downward by the second cylinder 402 again. When the plate contacts the support plate 103, the vacuum pump 401 and the second cylinder 402 are turned off. When the second cylinder 402 is turned off, the four suction nozzles 404 are in a pressing state against the plastic plate, thereby ensuring the stability of the plastic plate when being cut. At this time, the first drive motor 304 is turned on, and the cutting knife 305 will rotate under the drive of the first drive motor 304. Then, the cutting knife 305 is driven to move by moving the position of the first cylinder 106, thereby realizing the cutting of the plastic plate. In actual operation, since the first cylinder 106 is slidably connected to the cutting box 1, it is possible to set a motor to drive the screw rod to rotate, and the screw rod is threadedly connected to the first cylinder 106, so as to drive the first cylinder 106 to move, thereby realizing the cutting knife 305 The cutting groove 104 provided on the support plate 103 prevents the cutting knife 305 from damaging the support plate 103 during the cutting process. At this time, the plastic sheet is cut into two halves. At this time, the burrs generated during the cutting need to be processed. First, the half of the plastic sheet close to the end of the feed inlet 101 is adsorbed and moved upward by the adsorption mechanism 4, so as to increase the space for the grinding block 307 during the grinding burr process. Then, the conversion motor 302 is turned on to drive the mounting block 303 to rotate, so that the grinding block 307 rotates to the bottom of the first U-shaped plate 301. Then, the second drive motor 306 is turned on to drive the grinding block 307 to rotate. At the same time, the first cylinder 106 drives the grinding block 307 to move up and down, so as to grind off the burrs.During the grinding process, the grinding block 307 needs to be moved along the cutting direction so that the grinding block 307 can thoroughly grind the burrs on the plastic sheet. The movement of the grinding block 307 and the cutting knife 305 can share a driving mechanism, that is, the motor drives the screw rod to rotate, thereby driving the first cylinder 106 to move, thereby driving the grinding block 307 and the cutting knife 305 to move. After the burrs of the plastic sheet at one end of the feed port 101 are removed, the half of the plastic sheet near the discharge port 102 is deburred by this method, so that the burrs of the plastic sheet can be immediately removed after the cutting is completed, so that the subsequent processing of the plastic sheet is easier and more relaxed.

[0040] like Figure 4 and Figure 7 As shown, a first slide groove 107 is provided on the top of the cutting box 1, a first slide block 108 is fixedly connected to the top of the first cylinder 106, and the first slide groove 107 is slidably connected to the first slide block 108;

[0041] In this embodiment, the design of the first sliding block 108 and the first sliding groove 107 allows the first cylinder 106 to be smoothly slidably connected to the cutting box 1 .

[0042] like Figure 1 and Figure 4 As shown, the inner wall of the cutting box 1 is located in the first slide groove 107 and is rotatably connected to the first screw rod 109, the first screw rod 109 is threadedly connected to the first slider 108, and one end of the outer wall of the cutting box 1 is fixedly connected to the first motor 110, and the output end of the first motor 110 is fixedly connected to the first screw rod 109;

[0043] In this embodiment, the first motor 110 is designed to provide driving force for the movement of the first cylinder 106. When the first motor 110 is turned on, it will drive the first screw rod 109 to rotate, thereby driving the first slider 108 to move, and then driving the first cylinder 106 to move. When the first cylinder 106 moves, it can drive the cutting knife 305 and the grinding block 307 to move, so that the cutting knife 305 can smoothly cut the plastic sheet, and the grinding block 307 can completely remove the burrs on the plastic sheet.

[0044] like Figures 8 to 9As shown, a second U-shaped plate 308 is fixedly connected to the bottom of the mounting block 303, the second U-shaped plate 308 is fixedly connected to the first drive motor 304, the second U-shaped plate 308 is rotatably connected to the cutting knife 305, a first steering motor 309 is fixedly connected to the top of the mounting block 303, a third U-shaped plate 310 is fixedly connected to the output end of the first steering motor 309, a second steering motor 311 is fixedly connected to one end of the third U-shaped plate 310, a support shaft 312 is fixedly connected to the output end of the second steering motor 311, the support shaft 312 is fixedly connected to the second drive motor 306, and the support shaft 312 is rotatably connected to the third U-shaped plate 310;

[0045] In this embodiment, during the grinding process, the second steering motor 311 can adjust the angle of the output shaft of the second drive motor 306, thereby driving the grinding block 307 to change its angle. The first steering motor 309 can drive the grinding block 307 to rotate. Under the joint action of the first steering motor 309 and the second steering motor 311, the grinding block 307 can flexibly adjust its own position, thereby facilitating the grinding of burrs on the plastic sheet.

[0046] like Figure 4 and Figure 6 As shown, the inner wall of the cutting box 1 is located at both ends of the support plate 103 and is fixedly connected with a slide rod 117, and the two ends of the support plate 103 are fixedly connected with a sleeve ring 118, and the slide rod 117 is slidably connected with the sleeve ring 118;

[0047] In this embodiment, the support plate 103 is supported by the design of the slide rod 117, so that the plastic sheet can be stably placed on the support plate 103, thereby improving the stability of the cutting process. The support plate 103 can be smoothly slidably connected to the slide rod 117 through the design of the ring 118.

[0048] like Fig.10 As shown, the input end of the vacuum pump 401 is connected to a hose 406, and the end of the hose 406 away from the vacuum pump 401 is connected to a first three-way pipe 407, and the two ends of the first three-way pipe 407 are respectively connected to second three-way pipes 408, and the two ends of the two second three-way pipes 408 are respectively connected to four suction nozzles 404;

[0049] In this embodiment, the four suction nozzles 404 can be smoothly connected to the input end of the vacuum pump 401 through the hose 406, the first three-way pipe 407 and the second three-way pipe 408. In addition, the design of the hose 406 allows the second cylinder 402 to smoothly drive the suction nozzle 404 to move downward.

[0050] like Fig.10 As shown, the center of the bottom of the connecting plate 403 is fixedly connected to an electric telescopic rod 409, the output end of the electric telescopic rod 409 is fixedly connected to a pressing plate 410, and a rubber pad 411 is provided at the bottom of the pressing plate 410;

[0051] In this embodiment, since the second cylinder 402 directly drives the suction nozzle 404 to press the plastic sheet, the suction nozzle 404 and the suction cup 405 are prone to damage, the electric telescopic rod 409 drives the pressing plate 410 to move downward to press the plastic sheet, which not only increases the stability of the plastic sheet during cutting, but also eliminates the need for the suction nozzle 404 and the suction cup 405 to press the plastic sheet, thereby extending the service life of the suction nozzle 404 and the suction cup 405. The design of the rubber pad 411 can prevent the pressing plate 410 from pressing indentations on the plastic sheet.

[0052] like Figure 1 and Fig.11 As shown, it also includes a dust collection mechanism 5, which includes a dust collection head 501, a telescopic tube 502 and a dust collector 503. The dust collection head 501 is slidably connected to the inner wall of the cutting box 1 and is located above the support plate 103. The two ends of the dust collection head 501 are respectively connected to the telescopic tube 502. One end of the outer wall of the cutting box 1 is fixedly connected to the dust collector 503. The input end of the dust collector 503 is connected to the third three-way tube 504. The two ends of the third three-way tube 504 are respectively connected to the two telescopic tubes 502.

[0053] In this embodiment, the design of the dust collection mechanism 5 can absorb the debris generated during the cutting and grinding process, thereby ensuring the cleanliness of the support plate 103 and the inside of the cutting box 1. After the vacuum cleaner 503 is turned on, the debris located at the vacuum head 501 will be sucked away and enter the interior of the vacuum cleaner 503 through the telescopic tube 502.

[0054] like Figure 6 and Fig.11 As shown, the two ends of the inner wall of the cutting box 1 are respectively provided with second slide grooves 111, and the two ends of the dust collector head 501 are respectively fixedly connected with second sliders 505, and the second slide grooves 111 are slidably connected with the second sliders 505;

[0055] In this embodiment, the design of the second sliding block 505 and the second sliding groove 111 allows the vacuum head 501 to be smoothly slidably connected to the cutting box 1 .

[0056] like Figures 3 to 6 As shown, the inner wall of the cutting box 1 is located in the second slide groove 111 and is rotatably connected to the second screw rod 112, the second screw rod 112 is threadedly connected to the second slider 505, one end of the second screw rod 112 extends to the outside of the cutting box 1, and is fixedly connected to a synchronous wheel 113, the two synchronous wheels 113 are meshed and connected to a synchronous belt 114, one end of the side wall of the cutting box 1 is fixedly connected to a support arm 115, one end of the support arm 115 is fixedly connected to a second motor 116, and the output end of the second motor 116 is fixedly connected to the synchronous wheel 113;

[0057] In this embodiment, the design of the synchronous wheel 113 and the synchronous belt 114 allows the two second screw rods 112 to rotate synchronously, so that the second motor 116 can drive the second screw rod 112 to rotate, thereby driving the dust head 501 to move along the length direction of the second slide groove 111, so that the dust head 501 can absorb the debris on the entire support plate 103. In actual operation, in order to increase the debris cleaning effect, after the plastic plate is cut, the plastic plate cut in half can be lifted to the top of the dust head 501 by the adsorption mechanism 4, and then the support plate 103 is cleaned for the first time by the dust suction mechanism 5, and then the plastic plate near the feed port 101 is polished. After the plastic plate is polished, the second debris absorption is performed, and then the plastic plate near the discharge port 102 is polished. After the third debris cleaning is completed, the cleanliness of the top of the support plate 103 and the inside of the cutting box 1 can be well guaranteed by the three debris cleanings. At the same time, during cutting and polishing, the support plate 103 always covers the conveying roller 2, thereby ensuring the cleanliness of the conveying roller 2.

[0058] Working principle: First, place the plastic sheet on the conveyor roller 2. Under the conveyor roller 2, the plastic sheet will enter the cutting box 1 through the feed port 101. Then, open the two second cylinders 402. Driven by the second cylinders 402, the connecting plate 403 will move downward, thereby driving the suction nozzle 404 to move downward. When the suction cup 405 at the bottom of the suction nozzle 404 contacts the plastic sheet, turn on the vacuum pump 401. Under the action of the vacuum pump 401, a vacuum will be generated inside the suction cup 405, thereby firmly adsorbing the plastic sheet. At this time, turn on the second cylinder 402 to drive the plastic sheet to move upward. When the plastic sheet moves above the support plate 103, turn on the electric push rod 105. Driven by the electric push rod 105, The support plate 103 will move. When the opposite ends of the two support plates 103 are spliced ​​together, the second cylinder 402 is used to drive the plastic sheet to move downward again. When the plastic sheet contacts the support plate 103, the vacuum pump 401 is turned off, and the electric telescopic rod 409 is opened at the same time. Under the drive of the electric telescopic rod 409, the pressing plate 410 will move downward, thereby pressing the plastic sheet. At this time, the plastic sheet can be cut. At this time, the first drive motor 304 is turned on, and the cutting knife 305 will rotate under the drive of the first drive motor 304.
