Description

Technical Field

[0001] This utility model relates to the field of plastic particle crushing technology, and in particular to a plastic particle crushing device. Background Technology

[0002] Plastic granules refer to granular plastics, which are polymer compounds formed through addition or condensation polymerization. They can be processed into various shapes and retain their shape. In the process of making plastic products from plastic granules, pretreatment is necessary, and crushing the granules is a crucial step. The uniformity of the crushing directly determines the quality of the final plastic product.

[0003] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: When existing crushing devices crush plastic particles, although they can filter and separate the crushed plastic particles through a filter screen to make the plastic particles discharged from the crushing device uniform in size, after the filter screen completes the separation and filtration of plastic particles, plastic particles that are too large will accumulate on its surface, which will affect the filtration and separation efficiency of the filter screen and make it inconvenient to recycle and reprocess large-sized plastic particles. Utility Model Content

[0004] The technical problem to be solved by this utility model is that in the prior art, after the filter screen completes the separation and filtration of plastic particles, plastic particles with excessively large particles will accumulate on the surface, which will affect the filtration and separation efficiency of the filter screen. To this end, we propose a plastic particle crushing device.

[0005] To achieve the above objectives, this application adopts the following technical solution: a plastic granule crushing device, including a device housing, a feeding plate installed at an incline inside the device housing and extending through to the left side of the device housing, a filter separation plate installed at an incline inside the device housing, a servo motor provided on the left side of the device housing and extending through to the inside of the device housing and located above the filter separation plate, and a discharge port provided on the right side of the device housing; The servo motor is fixed to the left outer wall of the device housing by bolts. Two crushing components are rotatably connected inside the device housing and located above the feeding plate. One of the crushing components is fixedly connected to the output end of the servo motor on the left side and has a transmission bevel gear sleeved and fixed on the right side. The inner wall of the device housing is machined with annularly distributed convex teeth that mesh with the outer wall of the crushing component.

[0006] Preferably, the crushing component includes a support rod, which is rotatably connected to the inside of the device housing. A connecting gear is sleeved and fixed on the left outer wall of the support rod and rotatably connected to the inner wall of the device housing. A crushing roller is sleeved and fixed on the outer wall of the support rod.

[0007] Preferably, a connecting bevel gear is provided at one bottom end of the transmission bevel gear, and a support gear is fixedly connected to the bottom end of the connecting bevel gear and rotatably connected to the inside of the device housing through a bearing. A connecting rod is rotatably connected to the inside of the right side of the device housing and is located between the two crushing components. A transmission gear is sleeved and fixed at the top end of the connecting rod and is located at one end of the support gear. A spiral blade is sleeved and fixed on the outer wall of the connecting rod.

[0008] Preferably, the left side of the filter separation plate is higher than the right side of the filter separation plate, and the crushing component is distributed in parallel with the filter separation plate. The left side of the feeding plate is lower than the right side of the feeding plate. Both the feeding plate and the filter separation plate are installed at an inclination of 15 degrees.

[0009] Preferably, the connecting gears mesh with each other through tooth grooves, the top of the device housing is provided with a feed hopper located on the upper left side of the crushing assembly, and the inside of the device housing is provided with a crushing hopper that matches the crushing roller, with convex teeth distributed in a ring on the inner wall of the crushing hopper.

[0010] Preferably, the device housing has a transmission space inside that matches the connecting bevel gear, the transmission bevel gear, and the transmission gear. The transmission bevel gear and the connecting bevel gear mesh with each other through tooth grooves, and the transmission gear and the support gear mesh with each other through tooth grooves. The device housing has a transport chamber inside that matches the spiral blades, and one side of the top of the transport chamber is connected to the discharge port. A discharge trough is provided between the rightmost side of the filter separation plate and the transport chamber.

[0011] The technical effects and advantages of this utility model are as follows: In this invention, the vibration generated by the device housing during operation, and the fact that both the feeding plate and the filter separation plate are installed at a 15-degree angle, facilitates the rolling and separation of plastic particles on the surface of the filter separation plate. This allows small plastic particles to fall through the filter holes onto the feeding plate, while larger plastic particles continue to roll on the filter separation plate and fall into the conveying chamber inside the device housing through the discharge chute. This reduces the accumulation of large plastic particles on the filter separation plate, thus minimizing its impact on the filtration efficiency.

[0012] In this invention, large-sized plastic particles from the surface of the filter separation plate roll into the transport bin through the discharge chute. The rotation of the transmission bevel gear drives the rotation of the connecting bevel gear, which in turn causes the connecting rod to rotate. This rotation, through the rotation of the spiral blades, transports the large particles remaining inside the device housing to the outside of the device, facilitating secondary processing and crushing of the large plastic particles.

[0015] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0016] Reference Figures 1-5 As shown, this utility model provides a technical solution: a plastic granule crushing device, including a device housing 1, a feeding plate 2 is installed obliquely inside the device housing 1 and extends to the left side of the device housing 1, a filter separation plate 201 is installed obliquely inside the device housing 1, a servo motor 3 is provided on the left side of the device housing 1 and extends into the inside of the device housing 1 and is located above the filter separation plate 201, and a discharge port 4 is provided on the right side of the device housing 1; The servo motor 3 is fixed to the left outer wall of the device housing 1 by bolts. Two crushing components 301 are rotatably connected inside the device housing 1 and are located above the feeding plate 2. One of the crushing components 301 is fixedly connected to the output end of the servo motor 3 on the left side and has a transmission bevel gear 303 sleeved and fixed on the right side. The inner wall of the device housing 1 is machined with annularly distributed convex teeth 302, which mesh with the outer wall of the crushing component 301.

[0017] The filter separation plate 201 and the feeding plate 2 are installed at an incline inside the device housing 1, which facilitates the pulverized plastic particles to roll at an incline on the filter separation plate 201 and the feeding plate 2. This makes it easier for the filter separation plate 201 to filter and separate the pulverized plastic particles more quickly. At the same time, the pulverizing component 301 and the protruding teeth 302 cooperate with each other to improve the pulverizing effect of the pulverizing component 301 on the plastic particles.

[0018] Reference Figures 2-5 As shown in this embodiment: the crushing component 301 includes a support rod 3011, which is rotatably connected to the inside of the device housing 1. A connecting gear 3012 is sleeved and fixed on the left outer wall of the support rod 3011 and rotatably connected to the inner wall of the device housing 1. A crushing roller 3013 is sleeved and fixed on the outer wall of the support rod 3011. The two crushing rollers 3013 are driven to rotate in opposite directions by the connecting gear 3012 in the crushing component 301, thereby completing the cutting and crushing of plastic particles.

[0019] Reference Figure 4 and Figure 5 As shown in this embodiment: A connecting bevel gear 401 is provided at the bottom of one side of the transmission bevel gear 303. A support gear 402 is fixedly connected to the bottom of the connecting bevel gear 401 and is rotatably connected to the inside of the device housing 1 through a bearing. A connecting rod 404 is rotatably connected to the inside of the right side of the device housing 1 and is located between the two crushing components 301. The transmission gear 403 is sleeved and fixed at the top of the connecting rod 404 and is located at one end of the support gear 402. A spiral blade 405 is sleeved and fixed on the outer wall of the connecting rod 404. The rotation of the transmission bevel gear 303 drives the connecting bevel gear 401 to rotate, so that the rotation of the connecting rod 404 drives the large particles remaining inside the device housing 1 to the outside of the device through the rotation of the spiral blade 405, which facilitates the secondary processing and crushing of large plastic particles.

[0020] Reference Figure 1 and Figure 2As shown in this embodiment: the left side of the filter separation plate 201 is higher than the right side of the filter separation plate 201, and the crushing component 301 is parallel to the filter separation plate 201. The left side of the feeding plate 2 is lower than the right side of the feeding plate 2. The feeding plate 2 and the filter separation plate 201 are both installed at a 15-degree angle. By installing the feeding plate 2 and the filter separation plate 201 at a 15-degree angle, it is convenient for the crushed plastic particles to fall onto the filter separation plate 201 and roll and separate, so that the plastic particles rolled out on the feeding plate 2 are of uniform size.

[0021] Reference Figure 2 and Figure 3 As shown in this embodiment: the connecting gears 3012 mesh with each other through tooth grooves, the top of the device housing 1 is provided with a feeding hopper, which is located on the upper left side of the crushing component 301, and the inside of the device housing 1 is provided with a crushing hopper that matches the crushing roller 3013, and the protruding teeth 302 are distributed in a ring on the inner wall of the crushing hopper. By providing a crushing hopper that matches the crushing roller 3013 inside the device housing 1, and the protruding teeth 302 being distributed in a ring on the inner wall of the crushing hopper, it is convenient for plastic particles to be repeatedly cut and squeezed by the crushing roller 3013 and the protruding teeth 302 inside the crushing hopper, thereby improving the crushing efficiency and uniformity of plastic particles.

[0022] Reference Figure 4 and Figure 5 As shown in this embodiment: the device housing 1 has a transmission space inside that matches the connecting bevel gear 401, the transmission bevel gear 303, and the transmission gear 403. The transmission bevel gear 303 and the connecting bevel gear 401 mesh with each other through tooth grooves, and the transmission gear 403 and the support gear 402 mesh with each other through tooth grooves. The device housing 1 has a transport chamber inside that matches the spiral blade 405, and one side of the top of the transport chamber is connected to the discharge port 4. A discharge trough is provided between the rightmost side of the filter separation plate 201 and the transport chamber. The large-sized plastic particles on the surface of the filter separation plate 201 roll into the transport chamber through the discharge trough. At the same time, the rotation of the spiral blade 405 drives the plastic particles inside the transport chamber to spiral upward and be discharged from the discharge port 4.

[0023] Working principle: The user starts the servo motor 3, which drives the crushing component 301 to rotate. The plastic particles to be processed are conveyed into the device housing 1 through the feeding hopper. The connecting gear 3012 rotates, which drives the two crushing rollers 3013 to rotate. The crushing rollers 3013 rotate inside the crushing hopper to cut and crush the plastic particles. At the same time, the plastic particles are repeatedly cut and squeezed by the crushing rollers 3013 and the teeth 302 inside the crushing hopper, which improves the crushing efficiency and uniformity of the plastic particles. The crushed plastic particles fall onto the filter separation plate 201 through the crushing hopper. Due to the vibration generated by the device housing 1 during operation, and the fact that both the feeding plate 2 and the filter separation plate 201 are installed at a 15-degree angle, the plastic particles roll and separate on the surface of the filter separation plate 201. Small particles fall through the filter holes onto the feeding plate 2 and are discharged from the inside of the device housing 1 through the inclined feeding plate 2. Larger plastic particles continue to roll on the filter separation plate 201 and fall into the conveying chamber inside the device housing 1 through the discharge chute. This reduces the accumulation of large plastic particles on the filter separation plate 201, thus reducing its impact on the filtration efficiency.

[0024] Working principle: The rotation of the crushing component 301 causes the support rod 3011 to drive the transmission bevel gear 303 to rotate. The rotation of the transmission bevel gear 303 drives the connecting bevel gear 401 to rotate. The rotation of the connecting bevel gear 401 drives the support gear 402 to rotate. The rotation of the support gear 402 drives the transmission gear 403 to rotate. The rotation of the transmission gear 403 synchronously drives the connecting rod 404 to rotate. The rotation of the connecting rod 404 drives the spiral blades 405 to rotate. The rotation of the spiral blades 405 causes the large plastic particles in the transport bin to spiral upward and be discharged into the device housing 1 through the discharge port 4. This allows the workers to add the crushed large plastic particles back into the device housing 1 for further crushing and processing.

[0025] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
