The process of cutting plastic raw materials is a process of placing the plastic raw material plate on a cutting device for cutting.

[0003] The current device for cutting plastic raw materials is a movable cutter head that cuts the plastic raw materials at high speed. However, the rotating cutting of the cutter head will generate a lot of plastic debris that splashes or scatters on the lathe. The plastic debris greatly affects the cutting efficiency, and the splashing debris is not good for the health of the operator.

[0004] The present invention aims to design a material cutting device for processing plastic raw materials which can remove plastic debris in time. Summary of the invention

[0005] In order to overcome the disadvantage that plastic debris is retained on the lathe during the processing of existing plastic raw materials, thus affecting the efficiency of plastic cutting, the present invention provides a plastic raw material processing cutting device capable of removing the plastic debris in time.

[0006] A cutting device for processing plastic raw materials includes a plastic cutting machine body and a cutting knife. The plastic cutting machine is provided with a cutting knife that moves horizontally back and forth. The plastic cutting machine is provided with a horizontal placement table. It also includes a cleaning mechanism and a collecting mechanism. The cleaning mechanism is connected to the cutting knife and can sweep away plastic debris generated by cutting on a plastic plate. The collecting mechanism is arranged on the side of the placement table and can collect the plastic debris and push it centrally.

[0007] Furthermore, the cleaning mechanism includes a guide rod, a slide seat, a brush and a limit spring.

[0014] Beneficial effects of the present invention:

[0015] 1. A cleaning mechanism and a collecting mechanism are provided. When the cutting knife moves back and forth to cut the surface of the plastic plate, the brush can sweep the plastic debris generated by the cutting into the limit frame, so as to keep the surface of the plastic plate clean and improve the cutting effect. The double-threaded screw is then driven by a motor to rotate, thereby driving the scraper to slide back and forth. The scraper pushes the plastic debris that falls into the limit frame to one end of the limit frame, which is convenient for the staff to clean up centrally. Compared with the existing plastic cutting machine that is not equipped with a cleaning device, this device can better keep the surface of the plastic plate clean, thereby ensuring the cutting quality, and also provides a guarantee for the health of the staff, and also reduces the burden of subsequent staff to clean up the plastic debris.

DETAILED DESCRIPTION

[0029] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0030] Example 1

[0031] A material cutting device for processing plastic raw materials, such as Figure 1 and Figure 2As shown, it includes a plastic cutting machine 1 body and a cutting knife 101. The plastic cutting machine 1 is provided with a cutting knife 101 that moves horizontally back and forth. The plastic cutting machine 1 is provided with a horizontal placement table. It also includes a cleaning mechanism 2 and a collecting mechanism 3. The cleaning mechanism 2 is connected to the cutting knife 101. The cleaning mechanism 2 can sweep away the plastic debris generated by cutting on the plastic plate. The collecting mechanism 3 is arranged on the side of the placement table. The collecting mechanism 3 can collect the plastic debris and push it centrally.

[0032] like Figure 1-Figure 4 As shown, the cleaning mechanism 2 includes a guide rod 201, a slide 202, a brush 203 and a limiting spring 204. The guide rod 201 is connected to the plastic cutting machine 1, and the slide 202 is limited and slidable on the guide rod 201. The side of the cutting knife 101 is connected to the limiting rod 205, and the end of the limiting rod 205 is slidably connected to the slide 202. The cutting knife 101 pushes the slide 202 through the limiting rod 205, and the brush 203 is slidably clamped on the slide 202, and the brush 203 is fixed by the limiting spring 204.

[0033] like Figure 1 and Figure 5 As shown, the collecting mechanism 3 includes a limit frame 301, a motor 302, a double-threaded screw 303, a scraper 304 and a transmission belt 305. The limit frame 301 is symmetrically fixed to the side of the above-mentioned placing table, the motor 302 is fixed to one end of the plastic cutting machine 1 by bolts, the double-threaded screw 303 is rotatably connected in the limit frame 301, and the double-threaded screws 303 on both sides are transmitted by the transmission belt 305. The output shaft of the motor 302 is connected to its double-threaded screw 303 through a coupling, the scraper 304 is connected to the double-threaded screw 303 by threads, and the scraper 304 is limited and slid on the inner wall of the limit frame 301.

[0034] The transmission belt 305 is wound around the ends of the two double-threaded screws 303. The plastic cutting machine 1 drives the cutting knife 101 to move back and forth to cut the surface of the plastic plate placed on the placing table. The brush 203 can sweep the plastic debris generated by the cutting into the limit frame 301. The inner wall of the slide 202 is provided with a slot, and the limit spring 204 can be snapped into the slot to adjust the height of the brush 203 according to the thickness of the plastic plate. The motor 302 is turned on to drive the double-threaded screw 303 to rotate, and the scraper 304 will slide back and forth in the limit frame 301 to sweep the plastic debris to the rear end of the limit frame 301, which is convenient for the staff to clean up in a centralized manner.

[0035] Example 2

[0036] On the basis of Example 1, Figure 1 , Figure 6 and Figure 7As shown, a cleaning mechanism 4 is also included, which includes a wedge-shaped push block 401, a fixed rod 402, an L-shaped contact rod 403, a return spring 404, a rotating rod 405 and a cleaning plate 406. The wedge-shaped push block 401 is fixedly connected to the slide seat 202, the fixed rod 402 is fixedly connected to the end of the plastic cutting machine 1, the rotating rod 405 is rotatably connected in the fixed rod 402, the upper end of the rotating rod 405 is hinged with an L-shaped contact rod 403, the L-shaped contact rod 403 slides horizontally in the fixed rod 402, a return spring 404 is connected between the L-shaped contact rod 403 and the fixed rod 402, the lower end of the rotating rod 405 is hinged with a cleaning plate 406, the cleaning plate 406 slides horizontally in the fixed rod 402, and the wedge-shaped push block 401 can be in frictional contact with the L-shaped contact rod 403.

[0037] When the plastic cutting machine 1 drives the cutting knife 101 to slide to the front end of the placement plate, the wedge-shaped push block 401 can contact and squeeze the L-shaped contact rod 403, so that the L-shaped contact rod 403 slides forward. Due to the lever principle, the rotating rod 405 will rotate, and the rotating rod 405 will push the cleaning plate 406 to slide backward. The cleaning plate 406 will contact the brush 203, and the cleaning plate 406 can shake off the plastic debris stuck on the brush 203, thereby ensuring that the brush 203 is clean and improving the cleaning efficiency of the brush 203 for plastic debris.

[0038] like Figure 8 As shown, a cam 502 is also included. An annular groove 501 is opened on the inner wall of the limiting frame 301 . The cam 502 is fixedly connected to the side of the scraper 304 . The scraper 304 is slidably connected in the annular groove 501 through the cam 502 .

[0039] The cam 502 and the annular groove 501 can prevent the scraper 304 from pushing the plastic debris back. The principle is that the annular groove 501 is two parallel sliding grooves with closed ends. When the double-threaded screw 303 rotates, the scraper 304 is driven to slide backward in the limit frame 301. At this time, the scraper 304 is located in the lower sliding groove of the annular groove 501 and can push the plastic debris in the limit frame 301 backward. When the scraper 304 slides to the rear end of the annular groove 501, the scraper 304 is reset and slides forward under the action of the double-threaded screw 303. At this time, the scraper 304 will slide to the annular groove 501 under the action of the cam 502. 01, at this time, the lower end of the scraper 304 is out of contact with the bottom surface of the limit frame 301, and the scraper 304 cannot push the plastic debris that continues to enter the limit frame 301. When the scraper 304 slides to the front end of the annular groove 501, the scraper 304 enters the lower slide groove of the annular groove 501 again. At this time, the lower end of the scraper 304 is in contact with the bottom surface of the limit frame 301, and the scraper 304 will scrape the plastic debris again when sliding backward, so that the scraper 304 always keeps pushing the plastic debris backward, thereby achieving the effect of collecting the plastic debris in a concentrated manner.

[0040] like Fig. 9 As shown, a cleaning brush 6 is also included. The cleaning brush 6 is fixed to the scraper 304 . The cleaning brush 6 is an annular brush. The cleaning brush 6 is sleeved on the outside of the double-threaded screw 303 .

[0041] The cleaning brush 6 can prevent plastic debris from getting stuck on the double-threaded screw 303 , so as the scraper 304 slides back and forth, the cleaning brush 6 can continuously clean the plastic debris in the threads of the double-threaded screw 303 .

[0042] like Fig.10 As shown, a collection box 7 is also included, and the collection box 7 is connected to the side of the plastic cutting machine 1. It should be pointed out that the collection box 7 is connected to the rear side of the plastic cutting machine 1, and the collection box 7 is docked with the rear end of the limit frame 301. Therefore, when the scraper 304 pushes the plastic debris to the rear end of the limit frame 301, the plastic debris can be introduced into the collection box 7, which is convenient for the staff to recycle.

[0043] like Figure 1 As shown, a tool hook 8 is also included. The tool hook 8 is arranged on the side of the plastic cutting machine 1. The tool hook 8 is used to hang tools commonly used by the staff.

[0044] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with the technology to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
