Description

Technical Field

[0001] The utility model relates to the technical field of pulverizers, in particular to a plastic pulverizer used for producing plastic products. Background Art

[0002] Plastic products are various daily necessities, industrial parts and other products made through plastic processing and molding processes. Plastic is a synthetic material composed of high molecular compounds. It has the characteristics of plasticity, corrosion resistance and light weight. Therefore, it is widely used in various fields. In the production process of plastic products, the raw materials need to be crushed. In the crushing process, a plastic crusher for the production of plastic products is needed.

[0003] After searching, the Chinese patent announcement number is: CN203678483U, which discloses a plastic crusher, including a machine body, a moving knife and a fixed knife installed inside the machine body, and a screen plate installed below the moving knife and the fixed knife. Inside the machine body, a thumbwheel knife that rotates in the opposite direction to the moving knife and engages with the moving knife is installed above the moving knife and the fixed knife; the machine body is a closed box structure, the upper part of the machine body is equipped with a feed port with a device to prevent material splashing, and the lower part of the machine body is equipped with a discharge port that matches the bag opening of the finished product packaging bag. This machine solves the problem that the traditional crusher has low working efficiency when the speed is low, and when the speed is high, the centrifugal force of the crushed material causes the crushed raw material to float up, so that the moving knife and the fixed knife cannot fully engage with the crushed material, thereby wasting power. The working efficiency is high. The traditional model with the same power can only crush 1 ton of plastic per hour, while this machine can crush 3 tons of plastic per hour. The closed structure of the machine body effectively reduces the dust flying during the operation of the crusher and reduces environmental pollution. However, during the actual use of the device, some plastics may be missed during the crushing process. The missed plastics will be directly collected and cannot be properly crushed for the second time, thereby reducing the practicality of the device. Utility Model Content

[0034] In one embodiment of the present invention, Figures 1 to 4 As shown, an embodiment is provided: a plastic crusher for producing plastic products, comprising a crushing box 1, the left and right sides of the front end of the inner wall of the crushing box 1 are rotatably connected with gears 3, the rear sides of the gears 3 are fixedly connected with crushing rollers 4, the bottom of the crushing box 1 is fixedly connected with a screening box 5, the left and right sides of the inner wall of the screening box 5 are rotatably connected with rotating rods 8, a filter belt 9 is arranged on the outer side of the rotating rod 8, and the two rotating rods 8 are connected by transmission through the filter belt 9, the left side of the front end of the screening box 5 and the right side of the front end of the crushing box 1 are rotatably connected with rotating wheels 6, the outer side of the rotating wheels 6 is arranged with a transmission belt 7, the two rotating wheels 6 are connected by transmission through the transmission belt 7, the rear sides of the rotating wheels 6 penetrate the corresponding crushing box 1 and the screening box 5 and are fixedly connected with the corresponding gears 3 and the rotating rod 8, the left side of the screening box 5 is connected with a material receiving trough 10, and the top of the material receiving trough 10 is connected with a hollow cylinder 11, A servo motor 12 is fixedly connected to the top of the hollow cylinder 11, and the output end of the servo motor 12 passes through the hollow cylinder 11 and is fixedly connected to a threaded column 13. A discharge pipe 14 is connected to the top right side of the hollow cylinder 11. A synchronous motor 19 is fixedly connected to the rear side of the screening box 5. The output end of the synchronous motor 19 passes through the screening box 5 and is fixedly connected to the corresponding rotating rod 8. A bottom cover 28 is provided at the bottom of the receiving trough 10, and a dust removal mechanism 2 is provided on the right side of the screening box 5; a support plate 15 is fixedly connected to the bottom of the screening box 5, and the top of the inner wall of the support plate 15 is connected to the discharge trough 16. Positioning blocks 23 are fixedly connected to the outer walls of the support plate 15, and positioning holes 24 are provided on the outer sides of the plurality of positioning blocks 23; a movable door 18 is provided at the top of the crushing box 1, and a hinge 17 is fixedly connected to the top of the movable door 18. The movable door 18 is rotatably connected to the crushing box 1 through the hinge 17;

[0035] Specifically, the synchronous motor 19 is started to drive the rotating rod 8, and the filter belt 9 on its outer side is rotated. As the rotating rod 8 rotates, the rotating wheel 6 on the bottom side will also move, and the two rotating wheels 6 are driven to rotate synchronously through the transmission belt 7. The upper rotating wheel 6 pushes the right gear 3, and drives the two gears 3 and the crushing roller 4 to rotate simultaneously through meshing transmission. The crushing roller 4 is used to crush impurities, and its fragments will adhere to the surface of the filter belt 9. Small, standard-compliant materials pass through the filter belt 9 and enter the discharge trough 16 for concentration, while large, substandard materials are sent to the receiving trough 10 as the filter belt 9 moves. The servo motor 12 is started to drive the threaded column 13 to rotate, and the materials in the receiving trough 10 are moved up along the hollow cylinder 11, and finally discharged into the crushing box 1 through the discharge pipe 14 for secondary or multiple crushing. The stability of the equipment during operation is improved by installing threaded parts on the positioning block 23, and the movable door 18 can be opened and closed by the hinge 17 to prevent the entry of external dust and impurities when the equipment is not in use.

[0036] Reference Figure 1 , Figure 3 and Figure 4 The dust removal mechanism 2 includes a water absorption cover 201, which is connected to the right side of the screening box 5. The right side of the water absorption cover 201 is fixedly connected to a fixed cover 202, and the inner side of the fixed cover 202 is fixedly connected to a fixed rod 204. The front and rear sides of the left end of the fixed rod 204 are rotatably connected to a pulley 205, and a belt 206 is arranged on the outer side of the pulley 205. The two pulleys 205 are connected by the belt 206. The right side of the fixed rod 204 is fixedly connected to a DC motor 203. The DC motor 2 The output end of 03 passes through the fixed rod 204 and is fixedly connected to the corresponding pulley 205. The right side of the pulley 205 is fixedly connected with a fan blade 207. The front and rear sides of the inner wall of the water absorption cover 201 are fixedly connected with a filter screen 208; the right side of the fan blade 207 passes through the filter screen 208 and is fixedly connected with a scraper 29. The bottom of the water absorption cover 201 is provided with an ash discharge port 30; the rear side of the crushing box 1 is fixedly connected with a water tank 20, the top of the water tank 20 is connected with a water pump 21, and the output end of the water pump 21 is connected with a spray plate 22;

[0037] Specifically, the DC motor 203 is started, and the two pulleys 205 are driven to rotate along the fixed rod 204 through the belt 206. When the pulley 205 rotates, it drives the fan blades 207 above to generate airflow, forming centrifugal force. This centrifugal force sucks impurities and dust generated by the material in the screening box 5 into the water absorption cover 201, and the filter screen 208 prevents impurities from entering the fixed cover 202 to ensure the normal operation of the fan blades 207. The water pump 21 is started to pump water in the water tank 20 into the spray plate 22, and the powder is sprayed by the spray plate 22. The dust generated during the crushing operation is reduced. When the dust removal mechanism 2 is working, the water absorption hood 201 initially absorbs the water to prevent impurities from sticking in it, which helps to better discharge it through the ash discharge port 30, and the remaining water is intercepted by the filter 208 together with the impurities. At the same time, the rotation of the fan blades 207 drives the scraper 29 to rotate along the outside of the filter 208 to scrape off the impurities attached thereto to ensure the stability of the filtering and ventilation effects. Such a design can effectively reduce dust when handling crushing work and maintain the efficient operation of the equipment.

[0038] Reference Figure 1 A controller 25 is fixedly connected to the left side of the front end of the crushing box 1, and the controller 25 is electrically connected to the servo motor 12, the synchronous motor 19, the water pump 21 and the DC motor 203 respectively; a housing 26 is fixedly connected to the outside of the controller 25, and a shield 27 is rotatably connected to the outside of the housing 26;

[0039] Specifically, the controller 25 can control the starting and operating power of the servo motor 12, the synchronous motor 19, the water pump 21 and the DC motor 203 respectively. At the same time, the housing 26 can enhance the protection capability of the controller 25, and the opening and closing of the protective cover 27 can prevent the controller 25 from being accidentally touched when it is not in use.

[0040] Working principle: Before using the device, first start the synchronous motor 19 to drive the rotating rod 8 on one side to rotate, and drive the filter belt 9 on the outside to rotate through the rotating rod 8. At this time, as the rotating rod 8 rotates, the rotating wheel 6 on the bottom side can also be driven to rotate, and the two rotating wheels 6 can be driven to rotate simultaneously through the transmission belt 7. At this time, the upper rotating wheel 6 can drive the right gear 3 to rotate, and drive the two gears 3 and the crushing roller 4 to rotate simultaneously through meshing transmission. At this time, the impurities crushed by the crushing roller 4 will fall on the surface of the filter belt 9, and small and qualified materials will pass through the filter belt 9 and be collected by the discharge trough 16, while large non-qualified materials will be sent to the receiving trough 10 through the rotation of the filter belt 9. At this time, start the servo motor 12 By driving the threaded column 13 to rotate, the material in the receiving trough 10 can be moved up along the hollow cylinder 11, and finally discharged into the crushing box 1 through the discharge pipe 14 for secondary or multiple crushing, thereby improving the practicality of the device, and starting the DC motor 203 can simultaneously drive the two pulleys 205 to rotate along the fixed rod 204 through the belt 206. When the pulley 205 rotates, it can drive the fan blade 207 thereon to rotate, so as to drive the airflow to generate centrifugal force, and the impurities and dust generated by the material in the screening box 5 can be sucked into the water absorption cover 201, and the filter screen 208 can prevent impurities from entering the fixed cover 202 to affect the operation of the fan blade 207, so as to reduce the impurity content inside the plastic after crushing, thereby improving the discharge quality.

[0041] The rest of this embodiment is the same as the first embodiment. The features not explained in this embodiment are all based on the explanations in the first embodiment and will not be described in detail here.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
