[0025] This part will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the drawings. The role of the drawings is to supplement the description of the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but it cannot be understood as a limitation on the protection scope of the present utility model.
[0026] Please refer to Figure 1-7 , the present utility model provides a technical solution: a cutting device for plastic product manufacturing, including a cutting machine body 1. An observation window 4 is inlaid on the surface of the cutting machine body 1. Through the setting of the observation window 4, the staff can observe the situation inside the cutting machine body 1, which is convenient for connecting the cutting situation of the pipeline, thereby improving the use effect of the device.
[0027] A feeding port 5 is opened on the surface of the cutting machine body 1. Four clamping plates 6 arranged at equal intervals in a circumferential manner are slidably connected to the inner wall of the cutting machine body 1. One side of the clamping plate 6 is an inclined surface, and the relative ends of the four clamping plates 6 are all arc-shaped, so that the clamping plate 6 can better clamp the pipeline.
[0028] The surfaces of the four clamping plates 6 are fixedly connected with first springs 7, and one ends of the four first springs 7 far away from the clamping plates 6 are fixedly connected with the interior of the cutting machine body 1, so as to drive the clamping plates 6 to reset.
[0029] A motor 8 is fixedly connected to the inner wall of the cutting machine body 1. The output end of the motor 8 is fixedly connected with a gear 9. Both the upper and lower sides of the inner wall of the cutting machine body 1 are fixedly connected with fixing rods 20. A toothed ring 15 is arranged inside the cutting machine body 1. The surface of the fixing rod 20 is slidably connected with the interior of the toothed ring 15. Thus, through the arrangement of the fixing rod 20, the position of the toothed ring 15 in the cutting machine body 1 can be limited. The surface of the toothed ring 15 is meshed with the surface of the gear 9. Four moving blocks 17 arranged at equal circumferential intervals are slidably connected to the inner wall of the toothed ring 15. First springs 7 are also arranged between the moving blocks 17 and the inner wall of the toothed ring 15, so as to drive the moving blocks 17 to reset.
[0030] The opposite ends of the four moving blocks 17 are fixedly connected with sector-shaped cutting blades 18 for cutting the pipeline. A moving plate 10 is slidably connected to the inner wall of the cutting machine body 1. Through holes are formed on the surface of the moving plate 10, ensuring that the pipeline can smoothly pass through the moving plate 10 for feeding. A rotating ring 16 is rotatably connected to the surface of the moving plate 10. A push rod 2 is fixedly connected to the surface of the rotating ring 16. An extrusion groove 19 is formed on the surface of the moving block 17. The inner wall of the extrusion groove 19 is an inclined surface. The surface of the push rod 2 is slidably connected with the inner wall of the extrusion groove 19. Thus, through the arrangement of the rotating ring 16, it can rotate synchronously with the toothed ring 15, ensuring that the push rod 2 is always connected to the moving block 17, and further ensuring the smooth operation of the device.
[0031] Furthermore, a baffle 13 is slidably connected to the inner wall of the cutting machine body 1. A second spring 14 is fixedly connected to the surface of the baffle 13. One end of the second spring 14 far away from the baffle 13 is fixedly connected to the inner wall of the cutting machine body 1, so as to drive the baffle 13 to reset. At the same time, the arrangement of the baffle 13 blocks the feeding length of the pipeline, thus facilitating the device to perform fixed-distance cutting on the pipeline.
[0032] An expansion link 12 is fixedly connected between the baffle 13 and the moving plate 10 to connect the baffle 13 and the moving plate 10 to each other. The expansion link 12 includes an inner rod 1201 and an outer rod 1203. The surface of the inner rod 1201 is slidably connected with the interior of the outer rod 1203, so as to adjust the length of the expansion link 12, and further ensure the smooth operation of the device. The opposite ends of the inner rod 1201 and the outer rod 1203 are respectively fixedly connected with the baffle 13 and the moving plate 10. A third spring 1202 is fixedly connected to the surface of the inner rod 1201. One end of the third spring 1202 far away from the inner rod 1201 is fixedly connected with the interior of the outer rod 1203.
[0033] On the upper side of the inner wall of the cutting machine body 1, a telescopic rod 12 is also fixedly connected. The lower end of the telescopic rod 12 is fixedly connected with a pushing block 21. The lower side of the pushing block 21 is a slope. Thus, through the setting that the lower side of the pushing block 21 is a slope, during the process of feeding the pipe, under the extrusion of the pipe on the slope of the pushing block 21, the pushing block 21 can be driven to rise smoothly in the cutting machine body 1. Then, after the pipe is cut, under the elastic force of the third spring 1202 in the telescopic rod 12, during the reset process of the pushing block 21, the cut pipe can be pushed, thus ensuring that the device can smoothly push and discharge the pipe.
[0034] A discharge port 11 is formed in the inner wall of the cutting machine body 1 for discharging the cut pipe. A collection box 3 is slidably connected to the bottom of the cutting machine body 1 for collecting the pipe.
[0035] Specifically, when cutting a plastic pipe, the worker inserts the pipe into the feed port 5, and then extrudes the slope of the clamping plate 6, thereby pushing the four clamping plates 6 to slide in the cutting machine body 1 and compressing the first spring 7, so that the four clamping plates 6 gradually fit the outer surface of the pipe. Subsequently, the pipe is continuously fed. Then, through the moving plate 10, the rotating ring 16 and the toothed ring 15 gradually contact the baffle 13, and then the baffle 13 is extruded and pushed, thereby compressing the second spring 14. The movement of the baffle 13 further pulls the inner rod 1201 and the moving plate 10 through the third spring 1202 by the outer rod 1203. Since the moving plate 10 is not blocked at this time, the moving plate 10 moves along with the movement of the baffle 13 at this time, and then drives the push rod 2 to extrude the inner wall of the extrusion groove 19, thereby driving the four moving blocks 17 to move relatively, so that the four cutting knives 18 gradually fit the surface of the pipe. When the four cutting knives 18 fit the surface of the pipe, since the movement of the cutting knives 18 and the moving blocks 17 is blocked, the movement of the push rod 2 is blocked, and then the moving plate 10 stops moving, so that the movement of the baffle 13 no longer drives the moving plate 10 to move, so that the third spring 1202 is stretched. Then, the motor 8 is started at this time, and then the toothed ring 15 is driven to rotate through meshing connection, and the four cutting knives 18 are driven to rotate, and then the surface of the pipe is cut. As the pipe is cut, the cutting knives 18 gain moving space again. Thus, under the elastic force of the third spring 1202, the moving plate 10 moves continuously, and then the push rod 2 extrudes the inner wall of the extrusion groove 19, thereby driving the four moving blocks 17 to continue to move relatively, so that the cutting knives 18 continue to feed and cut the pipe until the cutting of the pipe is completed. The device no longer uses a circular cutting knife to cut the pipe, but uses the four cutting knives 18 to perform circumferential cutting on the pipe, thereby improving the cutting speed of the device for plastic pipes, and thus improving the cutting efficiency of the device for plastic pipes, and having high popularization value and practicability.
[0036] Working principle: The staff inserts the pipeline into the feed port 5, and gradually contacts the baffle 13 through the moving plate 10, the rotating ring 16 and the toothed ring 15, and then squeezes and pushes the baffle 13, thereby compressing the second spring 14. At the same time, the moving plate 10 moves along with the movement of the baffle 13, so that the four cutting knives 18 gradually fit the surface of the pipeline. When the four cutting knives 18 fit the surface of the pipeline, since the movement of the cutting knives 18 and the moving blocks 17 is blocked, the movement of the push rod 2 is blocked, and then the moving plate 10 stops moving, so that the movement of the baffle 13 no longer drives the moving plate 10 to move, so that the third spring 1202 is stretched. At this time, the motor 8 is started, and then the toothed ring 15 is driven to rotate through meshing connection, and the four cutting knives 18 are driven to rotate, and then the surface of the pipeline is cut. As the pipeline is cut, the cutting knives 18 gain moving space again. Thus, under the elastic force of the third spring 1202, the moving plate 10 continues to move, and then the push rod 2 squeezes the inner wall of the extrusion groove 19, thereby driving the four moving blocks 17 to continue to move relatively, and then the cutting knives 18 continue to feed and cut the pipeline until the cutting of the pipeline is completed.

However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the purpose of the present invention.
