Description

Technical Field

[0001] This invention belongs to the field of ABS plastic production technology, and specifically relates to a granulation crushing mechanism for ABS plastic production. Background Technology

[0002] Plastic pellets are raw materials used for storing, transporting, and processing plastics in a semi-finished form. They can be used to manufacture various plastic products and are a widely used material. To reduce environmental pollution, waste plastic products can be crushed and recycled into plastic pellets for use in manufacturing new plastic products.

[0003] The ABS plastic granule crushing device described in patent CN119388629A connects a spacing adjustment component and a particle size sensing component. The spacing adjustment component is adjusted in real time based on the particle size detected by the particle size sensing component, realizing feedback adjustment of the crushing mechanism. It can automatically adjust according to the actual production situation without manual intervention, which greatly improves the production efficiency. However, a lot of cutting dust is generated when cutting raw materials. The invention cannot effectively recover this dust, which easily pollutes the air and causes waste. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a granulation and crushing mechanism for ABS plastic production, which has the advantage of recycling and cutting powder.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a granulation crushing mechanism for ABS plastic production, comprising a frame, a cylinder fixedly connected to the bottom outer wall of the frame, a blade holder fixedly connected to the sliding end of the cylinder, the blade holder being slidably connected to the frame, a rotating drum with internal and external ventilation rotatably connected to the bottom outer wall of the blade holder, a replaceable cutter fixedly connected to the outer wall of the rotating drum, a drive device being driven to one end of the rotating drum, a dust collection device being rotatably connected to the other end of the rotating drum, the dust collection device being connected to the inner wall of the rotating drum, and a retaining ring for clamping the blade holder being provided on the outer wall of the rotating drum.

[0006] The above technical solution facilitates ease of use. The cutter on the rotating drum can be replaced as needed to cut particles of different sizes. When the cutter needs to be replaced, the cutter holder is pushed out by the cylinder, causing the rotating drum to move out of the frame. Then, the retaining ring is removed, and the rotating drum can be taken off, allowing the cutter to be replaced. At the same time, powder is generated during cutting, which can be collected by a dust collection device, thereby reducing air pollution and facilitating material recycling.

[0007] Preferably, the tool holder includes a sliding frame box, the top outer wall of the frame box is rotatably connected to a top cover, the outer wall of the frame box is fixedly connected to a vertical frame, and an electric push rod is rotatably connected between the vertical frame and the outer wall of the top cover.

The bottom outer wall of the frame is fixedly connected to a hanger, the inner wall of the hanger is fixedly connected to a bearing, and the bottom outer wall of the stand is fixedly connected to a drive plate.

[0010] The above technical solution can serve as a suspension mechanism. After the frame box is pushed out by the cylinder, it can be hung on the frame by the limiting wings on both sides, which makes it easy to replace the cutter.

[0012] The above technical solution can increase the dust collection area. Since there are many air inlets on the cylinder and the air inlets are distributed along the axis of the rotating cylinder, the absorption area can be larger.

[0013] Preferably, the cutter includes a sleeve for fitting onto the rotating drum, and the outer wall of the sleeve is fixedly connected to a retaining ring that is snapped onto one side of the rotating drum.

[0014] The above technical solution can achieve the installation effect. Since the cutter needs to be disassembled on the rotating drum, the cutter is divided into a sleeve and a retaining ring to facilitate the disassembly of the cutter.

[0019] Preferably, the driving device includes an electric motor installed inside the tool holder, a rotating wheel fixedly connected to the outer wall of the electric motor, and a transmission belt drivingly connected to the outer wall of the rotating wheel.

[0020] The above technical solution can achieve a driving effect. The electric motor can control the transmission between the transmission belt and the rotating drum, thereby controlling the rotation of the rotating drum and thus performing cutting.

[0022] The above technical solution can effectively collect powder. After the powder is collected by a vacuum cleaner, it can be stored in a drawer, and the powder collection process can be observed through an observation window.

[0023] Preferably, the inner wall of the frame is provided with a material-forming wheel, the inner wall of the frame is provided with a feeding wheel, the inner wall of the frame is fixedly connected with a discharge plate, and the outer wall of the frame is fixedly connected with an inspection door.

[0024] The above technical solution can be used to transfer raw materials. The material roller can keep the ABS neat when it enters the frame. Then, it is transferred by the squeezing and friction of the feeding roller. After cutting, it is discharged through the unloading plate.

[0025] Compared with the prior art, the beneficial effects of the present invention are: 1. The cutter on the rotating drum can be replaced as needed to cut particles of different sizes. When the cutter needs to be replaced, the cutter holder is pushed out by the cylinder, so that the rotating drum is removed from the frame. Then, the retaining ring is removed, and the rotating drum can be taken off. This allows the cutter to be replaced. At the same time, powder is generated during cutting. The powder can be collected by the dust collection equipment, which can reduce air pollution and facilitate material recycling.

[0026] 2. The opening and closing of the top cover can be controlled by an electric push rod, which makes it convenient for users to maintain and test the equipment. After the rack box is pushed out by the cylinder, the rack box can be hung on the frame by the limiting wings on both sides, which makes it easy to replace the cutter and increases the dust collection area. Since there are many air inlets on the cylinder and the air inlets are distributed along the axis of the rotating cylinder, there is a larger absorption area. Attached Figure Description

Then, the retaining ring 12 is removed, and the rotating drum 4 can be taken off, so that the cutter 5 can be replaced. At the same time, powder is generated during cutting, which can be collected by the dust collection device 7, thereby reducing air pollution and facilitating material recycling.

The ABS can be kept neat when entering the frame 1 by the straightening wheel 8, and then conveyed by the squeezing and friction of the feeding wheel 9. After cutting, it is discharged through the unloading plate 10.

[0038] The working principle and usage process of this invention: The cutter 5 on the rotating drum 4 can be replaced as needed, thus cutting particles of different sizes. When the cutter 5 needs to be replaced, the blade holder 3 is pushed out by the cylinder 2, causing the rotating drum 4 to move out of the frame 1. Then, the retaining ring 12 is removed, and the rotating drum 4 can be taken off, allowing the cutter 5 to be replaced. At the same time, powder is generated during cutting, which can be collected by the dust collection device 7, thereby reducing air pollution and facilitating material recovery.

When the rotation speed of the rotating drum 4 remains constant, the size of the blades 5002 can be controlled by changing the number of blades 5002.

The ABS can be kept neat when entering the frame 1 by the straightening wheel 8, and then conveyed by the squeezing and friction of the feeding wheel 9. After cutting, it is discharged through the discharge plate 10.
