Description

Technical Field

[0001] The invention belongs to the technical field of plastic processing, in particular to a plastic processing plastic particle crushing device and a process thereof. Background Art

[0002] Plastic pellets are raw materials for storing, transporting and processing plastics in the form of semi-finished products. They can be used to make various plastic products and are widely used materials. In order to reduce environmental pollution, discarded plastic products can be crushed and remade into plastic pellets for the manufacture of new plastic products.

[0003] When the existing plastic particle crusher is crushing plastic particles, since the plastic particles are small and the particles are easy to escape from the grinding and crushing zone during the crushing process, there will still be large plastic particles in the crushed particles. In addition, the recycling of plastic particles is also relatively cumbersome, and the particle fragments are easy to spread into the external environment, resulting in a low yield rate. Therefore, improvement is needed. Summary of the invention

[0004] In view of the shortcomings of the prior art, the present invention solves the technical problems thereof by adopting a technical solution: a plastic processing plastic particle crushing device, comprising a fixing device, a counterweight plate is fixedly connected to the bottom of the fixing device, a control component is arranged at the bottom of the counterweight plate, a cover closing device is arranged at the bottom of the control component, and a docking device is arranged at the bottom of the cover closing device; The cover closing device comprises a lower cover shell, the upper surface of which is evenly provided with docking plugs, the top of the inner wall of the lower cover shell is fixedly connected with a conical rotating plate, the lower surface of which is evenly provided with friction steel balls through rotating grooves, and a guide opening is opened at the axis center of the inner cavity of the conical rotating plate; The docking device includes a concave chassis, and the outer surfaces of the concave rotating plate and the concave chassis are embedded with friction steel balls for grinding, and the concave rotating plate can be docked with the concave chassis. At this time, the downward pressure cover shell will be sleeved on the outside of the concave chassis to prevent the internal plastic particles from flying out. A discharge port is opened at the axis center of the concave chassis, and the bottom of the concave chassis is fixedly connected to a sleeve bottom shell. The left side of the inner wall of the sleeve bottom shell is rotatably connected to a control wheel through a horizontal frame plate, and a guiding device is arranged on the right side of the inner wall of the sleeve bottom shell.

[0005] Furthermore, the control component includes a torsion cylinder, and passive wheels are evenly arranged at the bottom of the inner cavity of the torsion cylinder. The axis of the passive wheels is rotatably connected to a telescopic connecting rod. A propulsion device is arranged at the axis of the inner cavity of the torsion cylinder. The torsion cylinder directly drives the cover closing device below through the telescopic connecting rod to grind the plastic particles inside the concave bottom plate. The lower surface of the counterweight plate is fixedly connected to the upper surface of the torsion cylinder. There are four passive wheels. The outer surface of the passive wheels is rotatably connected to the inner cavity of the torsion cylinder through a rotating slide groove. The bottom end of the telescopic connecting rod is fixedly connected to the upper surface of the lower pressure cover shell through a docking plug.

[0006] Furthermore, the propulsion device includes a pressurized top cylinder, a hollow blow cylinder is fixedly connected to the axis of the inner wall of the pressurized top cylinder, a guide slot is evenly provided on the lower part of the outer surface of the hollow blow cylinder, a plug-in bottom tube is evenly provided at the bottom of the inner cavity of the hollow blow cylinder, a compression push cylinder is fixedly connected to the lower surface of the hollow blow cylinder, and the pressurized top cylinder pressurizes the inside of the compression push cylinder through the air inlet groove on the side, so that the compression push cylinder pushes the lower pressure cover shell to slide down steadily along the guide slot and is sleeved with the outer surface of the concave bottom plate. The bottom end of the compression push cylinder is fixedly connected to the axis of the upper surface of the lower pressure cover shell, the outer surface of the hollow blow cylinder is slidably connected to the axis of the inner cavity of the conical rotating plate through the guide slot, and the lower surface of the conical rotating plate is mutually squeezed with the inner wall of the concave bottom plate through the friction steel ball. The upper part of the outer surface of the hollow blow cylinder is rotatably connected to the axis of the inner wall of the twisting cylinder, the top of the hollow blow cylinder is fixedly connected to the axis of the inner cavity of the counterweight plate, and the bottom of the inner wall of the lower pressure cover shell is sleeved with the outer surface of the concave chassis. The counterweight plate can blow air into the inside of the merged concave chassis through the hollow blow cylinder to blow away the plastic particles gathered at the discharge port to a position close to the friction steel ball.

[0007] Further, the guiding device includes a switching turntable, and the upper and lower sides of the outer surface of the switching turntable are symmetrically provided with guide rails, the axis of the inner cavity of the switching turntable is provided with an axis rotation groove, the inner cavity of the switching turntable is evenly provided with docking ports, and the front and rear sides of the inner cavity of the switching turntable are symmetrically provided with upper sprayers through the docking ports, and the docking ports without upper sprayers can be docked with the discharge ports, and then the crushed plastic particles are guided downward for discharge. The upper and lower sides of the outer surface of the switching turntable are rotatably connected to the inner wall of the sleeve bottom shell through the guide rails, the axis of the inner cavity of the switching turntable is rotatably connected to the guide rod of the sleeve bottom shell, the side of the switching turntable is rollingly connected to the outer surface of the control wheel, and the guide rod used to limit the switching turntable is located at the eccentric part of the sleeve bottom shell to ensure that the switching turntable can rotate stably.

[0008] The beneficial effects of the present invention are as follows: 1. When the device is used to crush plastic particles, the combined cover device and the docking device are combined into a crushing container to crush the particles inside, and the crushed plastic particles can be discharged from the inside along the inclined surface of the concave bottom plate and the guide opening at the axis. During the crushing work, in order to ensure that the particles can fully contact with the friction steel balls, the axis inside the container will be blown through a hollow blow tube to disperse the particles that cannot be ground at the axis, thereby ensuring that the particles can be fully ground.

[0009] 2. The hollow blower disperses the plastic particles gathered at the axis by blowing air. Since the butt plug and the concave bottom plate can be assembled into a relatively sealed container after being sleeved, the internal particles can be prevented from diffusing to the outside due to wind force, so as to facilitate collection and ensure that the crushed particles can remain inside the container. During the discharge operation, the vibration generated by the contact of the friction steel balls can shake out the smaller particles inside, thereby achieving the effect of easy and efficient recovery of plastic particles to improve the actual yield rate.

[0010] 3. During processing, the discharge port at the bottom will be blocked by the upper sprayer of the switching turntable, and the upper sprayer and the hollow blow tube will work together to disperse the plastic particles at the discharge port to reduce the wind force of the hollow blow tube. When discharging, the docking port of the switching turntable will become the discharge port of the finished particles, and under the action of the wind force from top to bottom of the hollow blow tube, the downward discharge will be accelerated. Compared with the discharge action that relies solely on the gravity of the plastic particles themselves, this discharge speed and efficiency will be faster, thereby improving the actual production efficiency.

[0011] 4. The pressurized top cylinder can promote the contact between the capping device and the docking device through the actual pressure control effect. Therefore, when the friction steel ball contacts the internal plastic particles, the resistance of the capping device will also increase. At this time, the pressurized top cylinder can stop pressurizing and grind the plastic particles with relatively small pressure instead of crushing the particles with a large extrusion force, which will lead to the problem of shriveled plastic particles in the finished product and affect the subsequent recycling and use.

DETAILED DESCRIPTION

[0014] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0015] Example 1, please refer to Figure 1-Figure 5 The present invention provides a technical solution: a plastic processing plastic particle crushing device, comprising a fixing device 1, a counterweight plate 2 is fixedly connected to the bottom of the fixing device 1, a control component 3 is arranged at the bottom of the counterweight plate 2, a cover closing device 4 is arranged at the bottom of the control component 3, and a docking device 5 is arranged at the bottom of the cover closing device 4; The cover closing device 4 comprises a cover pressing shell 41, the upper surface of which is evenly provided with docking plugs 42, the top of the inner wall of the cover pressing shell 41 is fixedly connected with a conical rotating plate 43, the lower surface of which is evenly provided with friction steel balls 45 through rotating grooves, and a guide opening 44 is opened at the axis of the inner cavity of the conical rotating plate 43; The docking device 5 includes a concave chassis 51, and the outer surfaces of the concave rotating plate 43 and the concave chassis 51 are embedded with friction steel balls 45 for grinding, and the concave rotating plate 43 can be docked with the concave chassis 51. At this time, the lower pressure cover shell 41 will be sleeved on the outside of the concave chassis 51 to prevent the internal plastic particles from flying out. A discharge port 52 is opened at the axis center of the concave chassis 51, and a sleeve bottom shell 53 is fixedly connected to the bottom of the concave chassis 51. The left side of the inner wall of the sleeve bottom shell 53 is rotatably connected to a control wheel 54 through a horizontal frame plate, and a guide device 55 is arranged on the right side of the inner wall of the sleeve bottom shell 53.

[0016] The control component 3 includes a torsion cylinder 31, and passive wheels 33 are evenly arranged at the bottom of the inner cavity of the torsion cylinder 31. The axis of the passive wheels 33 is rotatably connected with a telescopic connecting rod 34. A propulsion device 35 is arranged at the axis of the inner cavity of the torsion cylinder 31. The torsion cylinder 31 directly drives the cover closing device 4 below through the telescopic connecting rod 34 to grind the plastic particles inside the concave bottom plate 51. The lower surface of the counterweight plate 2 is fixedly connected to the upper surface of the torsion cylinder 31. There are four passive wheels 33. The outer surface of the passive wheels 33 is rotatably connected to the inner cavity of the torsion cylinder 31 through a rotating slide groove 32. The bottom end of the telescopic connecting rod 34 is fixedly connected to the upper surface of the lower pressure cover shell 41 through a docking plug 42.

[0017] Before using the device to crush plastic particles, first lift up the bottom cover device 4 through the control component 3, open the docking device 5 below, put a certain amount of plastic particles into the interior of the concave bottom plate 51, and then push the cover device 4 down and buckle it on the outer surface of the concave bottom plate 51. At this time, press down the cover shell 41 to first surround the side of the concave bottom plate 51, and then the conical rotating plate 43 and the concave bottom plate 51 squeeze the plastic particles inside.

[0018] When the crushing work is performed, the torsion cylinder 31 will drive the passive rotating wheel 33 to rotate through the motor of the rotating slide groove 32, and then drive the lower telescopic connecting rod 34, pulling the docking plug cylinder 42 of the lower pressure cover shell 41 to rotate. At this time, the plastic particles between the conical rotating plate 43 and the concave bottom plate 51 are ground into fine fragments by the friction steel balls 45 at high speed.

[0019] In order to prevent the plastic particles from being concentrated at the discharge port 52, air will be blown into the combined cylinder through the hollow blow cylinder 353 at the axis of the propulsion device 35 during operation. Since the bottom end of the hollow blow cylinder 353 is facing the discharge port 52 and the discharge port 52 is blocked by the guide device 55 at this time, the wind will blow the plastic particles here to the inclined position of the concave bottom plate 51, so that the plastic particles are fully ground and crushed.

[0020] When the lower pressure cover shell 41 is sleeved on the outer surface of the concave bottom plate 51, in order to ensure that the inside of the combined cylinder can be blown normally, the lower pressure cover shell 41 is not tightly fitted with the concave bottom plate 51, and there will be enough gaps for air to pass through. However, the plastic particles are heavier and concentrated in the lower area of ​​the concave bottom plate 51, so it can be ensured that the particles are always located inside the combined cylinder for crushing.

[0021] Example 2, please refer to Figure 1-Figure 8 The present invention provides a technical solution: on the basis of Example 1, the propulsion device 35 includes a pressurized top cylinder 351, a hollow blow cylinder 353 is fixedly connected to the axis center of the inner wall of the pressurized top cylinder 351, a guide groove 354 is evenly opened at the lower part of the outer surface of the hollow blow cylinder 353, and a plug-in bottom tube 352 is evenly arranged at the bottom of the inner cavity of the hollow blow cylinder 353. A compression push cylinder 355 is fixedly connected to the lower surface of the hollow blow cylinder 353. The pressurized top cylinder 351 pressurizes the interior of the compression push cylinder 355 through the side air intake groove, so that the compression push cylinder 355 pushes the lower pressure cover shell 41 to slide down steadily along the guide groove 354 and is sleeved with the outer surface of the concave bottom plate 51. The bottom end of the compression push cylinder 355 is fixedly connected to the axis of the upper surface of the lower pressure cover shell 41, the outer surface of the hollow blow cylinder 353 is slidably connected to the axis of the inner cavity of the conical rotating plate 43 through the guide slide 354, and the lower surface of the conical rotating plate 43 is mutually squeezed with the inner wall of the concave bottom plate 51 through the friction steel ball 45. The upper part of the outer surface of the hollow blow cylinder 353 is rotationally connected to the axis of the inner wall of the torsion cylinder 31, the top of the hollow blow cylinder 353 is fixedly connected to the axis of the inner cavity of the counterweight plate 2, the bottom of the inner wall of the lower pressure cover shell 41 is sleeved with the outer surface of the concave bottom plate 51, and the counterweight plate 2 can blow air into the inside of the combined concave bottom plate 51 through the hollow blow cylinder 353 to blow away the plastic particles gathered at the discharge port 52 to the position close to the friction steel ball 45.

[0022] The guiding device 55 comprises a switching turntable 551, and guide rails 552 are symmetrically provided on the upper and lower sides of the outer surface of the switching turntable 551, and an axis rotation groove 553 is provided at the axis center of the inner cavity of the switching turntable 551, and the inner cavity of the switching turntable 551 is uniformly provided with docking ports, and the front and rear sides of the inner cavity of the switching turntable 551 are symmetrically provided with upper sprayers 554 through the docking ports, and the docking ports without upper sprayers 554 can be docked with the discharge port 52, and then the crushed plastic particles are guided downward and discharged. The upper and lower sides of the outer surface of the switching turntable 551 are rotatably connected to the inner wall of the sleeve bottom shell 53 through the guide rails 552, the axis center of the inner cavity of the switching turntable 551 is rotatably connected to the guide rod of the sleeve bottom shell 53, the side of the switching turntable 551 is rollingly connected to the outer surface of the control wheel 54, and the guide rod used to limit the switching turntable 551 is located at the eccentric position of the sleeve bottom shell 53 to ensure that the switching turntable 551 can rotate stably.

[0023] When the plastic particles inside the cylinder are crushed, the control wheel 54 drives the guide device 55 to rotate so that the opening of the switching turntable 551 is opposite to the discharge opening 52. At this time, the gas blown out by the hollow blow tube 353 will accelerate the internal plastic particle powder to be discharged downward, and then completely taken out from the inside of the device. After the processed plastic particles are collected, the control wheel 54 will rotate the upper sprayer 554 to a position opposite to the discharge opening 52, and then the air sprayed from bottom to top will cooperate with the blowing effect of the hollow blow tube 353 to disperse the particles gathered at the discharge opening 52, and then carry out the next round of crushing work.

[0024] The pressurized top cylinder 351 can pressurize the interior of the compression push cylinder 355, and then the compression push cylinder 355 expands to push the lower pressure cover shell 41 downward, thereby driving the axis of the lower pressure cover shell 41 to slide along the guide groove 354 in a directional manner. When the hollow blow cylinder 353 rotates, it can also directly drive the lower pressure cover shell 41 to twist through the guide groove 354, thereby achieving a crushing effect.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention.
