Description

Technical Field

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

[0002] Cable plastic raw material crushing and processing is the process of mechanically crushing, sorting, and converting the plastic outer layer of waste cables into recyclable plastic granules. The process first uses a stripper or crushing and sorting equipment to separate metals such as copper and aluminum. Then, the plastic shell enters a coarse crushing stage, where it is broken down into smaller fragments by a shredder or coarse crusher, and further crushed into more uniform granules by a fine crusher. To improve purity, the crushed plastic needs to pass through a vibrating screen or air classifier to remove impurities, and may be washed to remove residual stains. Finally, the processed plastic granules can be reused in the production of cable sheaths, plastic products, or as a modified raw material.

[0003] A search revealed that patent CN222290720U discloses a raw material crushing device for plastic product manufacturing. The raw material slides downwards along the surface of an inclined guide plate. Smaller pieces fall through through-holes in the guide plate to the surface of a second guide plate. The material falling from guide plates 1 and 2 exits through outlets 2 and 3, respectively. Material falling into a collection box 1 is compressed to reduce its volume. However, in actual production, this device has the following drawbacks: the crushed material has a short movement path when moving and screening on the guide plate, resulting in insufficient screening; secondly, the plastic used in cable production has a certain degree of elasticity. After the volume is reduced by compression, the plastic rebounds to some extent once the compression is released, requiring secondary transfer for bagging, which reduces work efficiency. Therefore, further improvements are needed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a plastic raw material crushing device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a plastic raw material crushing device, comprising a base plate, with support rods fixed at the four corners of the upper surface of the base plate, and a box body fixedly connected to the top of multiple support rods. A crushing component is fixed to one side of the top of the box body, and a first hopper and a second hopper are fixed to the bottom wall of the box body. A partition is fixed at the junction of the tops of the first hopper and the second hopper, and an inclined screen plate is fixed to the top of the partition plate and the inner side wall of the box body. Multiple baffles are fixed to the upper surface of the screen plate, and a packaging component is fixed to the upper surface of the base plate and below the first hopper.

[0006] Furthermore, the crushing assembly includes a feed hopper fixed to the top wall of the housing. Inside the feed hopper, two shafts are rotatably connected via bearings. Crushing rollers are fixed to the surfaces of both shafts. A drive motor is fixed to the outer wall of the feed hopper. The drive motor is fixedly connected to one of the shafts. The ends of the two shafts away from the drive motor are located outside the feed hopper and are fixed with gears. The two gears mesh with each other.

[0007] Furthermore, two inclined guide plates are fixed at the top of the feed hopper and above the two crushing rollers.

[0008] Furthermore, the baffles are arranged in an inclined and staggered manner on the upper surface of the screen plate.

[0009] Furthermore, a vibration motor is fixed to the lower surface of the screen plate.

[0010] Furthermore, the packaging assembly includes two vertical rods fixed to the upper surface of the base plate, and an annular frame is fixedly connected to the top of the two vertical rods. A packaging bag is fitted onto the surface of the annular frame in the opposite direction.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1-4 As shown, a plastic raw material crushing device is disclosed, comprising a base plate 1, with support rods 2 fixed at the four corners of the upper surface of the base plate 1, and a box body 3 fixedly connected to the top of the multiple support rods 2. A crushing component 4 is fixed to one side of the top of the box body 3, and a first feeding hopper 5 and a second feeding hopper 6 are fixed to the bottom wall of the box body 3. A partition 7 is fixed at the junction of the top of the first feeding hopper 5 and the second feeding hopper 6. An inclined screen plate 8 is fixed to the top of the partition 7 and the inner side wall of the box body 3. Multiple baffles 9 are fixed to the upper surface of the screen plate 8, and a packaging component 11 is fixed to the upper surface of the base plate 1 and below the first feeding hopper 5.

[0024] The crushing assembly 4 includes a feed hopper 41 fixed to the top wall of the housing 3. Inside the feed hopper 41, two shafts 42 are rotatably connected by bearings. Crushing rollers 43 are fixed on the surface of both shafts 42. A drive motor 45 is fixed to the outer wall of the feed hopper 41. The drive motor 45 is fixedly connected to one of the shafts 42. The ends of the two shafts 42 away from the drive motor 45 are located outside the feed hopper 41 and are fixed with gears. The two gears mesh with each other.

[0025] In this embodiment, both crushing rollers 43 have strip-shaped crushing ridges on their outer surfaces, and the strip-shaped ridges on the two crushing rollers 43 mesh with each other. After the drive motor 45 is started, under the action of the meshing transmission of the two gears, the drive motor 45 will drive the two crushing rollers 43 to rotate in opposite directions. When plastic passes between the two crushing rollers 43, the material is squeezed, torn and crushed by the two crushing rollers 43.

[0026] Two inclined guide plates 44 are fixed at the top of the feed hopper 41 and above the two crushing rollers 43.

[0027] By setting the guide plate 44, the plastic can be guided between the two crushing rollers 43.

[0028] Multiple baffles 9 are arranged at an angle and in an alternating manner on the upper surface of the screen plate 8.

[0029] The crushed plastic falls onto the surface of screen plate 8 and slides down it. Large particles are discharged from the second hopper 6. A collection box can be placed at the bottom of the second hopper 6 to collect the large particles. The collected large particles can be poured back into hopper 41 for secondary crushing. Small particles pass through the mesh of screen plate 8 and are discharged from the first hopper 5. The multiple baffles 9 on the surface of screen plate 8 allow the material to stay on the surface of screen plate 8 for a longer time, thereby improving the screening effect.

[0030] A vibration motor 10 is fixed on the lower surface of the screen plate 8.

[0031] In this embodiment, although the screen plate 8 is fixedly connected, the vibration motor 10 is directly fixed to the lower surface of the screen plate 8, so it can still drive the screen plate 8 to vibrate slightly. This prevents materials from remaining on the surface of the screen plate 8.

[0032] The packaging component 11 includes two vertical rods 111 fixed to the upper surface of the base plate 1. The top ends of the two vertical rods 111 are fixedly connected to an annular frame 112, and a packaging bag 113 is sleeved on the surface of the annular frame 112 in the opposite direction.

[0033] The material discharged from the first hopper 5 will fall directly into the packaging bag 113, realizing the direct collection of small particulate materials.

[0034] A cylinder 12 is fixed to the lower surface of the first hopper 5. A pressure frame 13 is fixed to the bottom telescopic end of the cylinder 12, and the pressure frame 13 is located directly above the annular frame 112.

[0035] When securing the packaging bag 113, first place the packaging bag 113 under the annular frame 112, then pass the top of the packaging bag 113 through the annular frame 112, and fold the opening of the packaging bag 113 outwards to fit over the surface of the annular frame 112. Next, activate the cylinder 12 to extend, causing the pressure frame 13 to descend. The pressure frame 13 presses down on the opening of the packaging bag 113, thus securing the packaging bag 113. After filling with materials, activate the cylinder 12 to shorten, causing the pressure frame 13 to move upwards. This allows the opening of the packaging bag 113 to be detached from the surface of the annular frame 112. After removing the packaging bag 113, another packaging bag 113 can be used for packaging.

[0036] In this embodiment, a control cabinet is installed on the upper surface of the base plate 1. The control cabinet contains a controller, which can be a Siemens PLC S7-1200 controller. The vibration motor 10 is an OLI MVE 100 / 2, the cylinder 12 is an SMCCDJ2B10-15, and the drive motor 45 is not specifically limited in model. During operation, the controller centrally controls the operation of the vibration motor 10, cylinder 12, and drive motor 45.

[0037] Working principle: Raw materials are poured into hopper 41 and guided by guide plate 44 into the space between two crushing rollers 43. The two rotating crushing rollers 43 crush the raw materials, which then fall onto the surface of screen plate 8. The raw materials slide down the surface of screen plate 8, and large particles are discharged from the second discharge hopper 6. A collection box can be placed at the bottom of the second discharge hopper 6 to collect the large particles. The collected large particles can be poured back into hopper 41 for secondary crushing, while small particles pass through the mesh of screen plate 8 and are discharged from the first discharge hopper 5. The material discharged from the first discharge hopper 5 falls directly into the packaging bag 113, achieving direct collection of small particles.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it.
