Technical Field

[0001] This utility model relates to a plastic recycling and screening device for cutting equipment, and is situated in the technical field of plastic processing and recycling equipment. Background Technology

[0002] Existing plastic cutting and processing equipment typically generates a large amount of plastic particles and dust during operation. This debris and dust are usually treated as waste, resulting in a waste of materials and costs. Moreover, the dust generated also greatly affects the operating environment of the entire equipment. Therefore, our company needs to propose an improved plastic recycling and screening device for cutting equipment. Utility Model Content

[0003] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a plastic recycling and screening device for cutting equipment, so as to solve the problems mentioned in the background art.

[0004] This utility model is achieved through the following technical solution: a plastic recycling and screening device for cutting equipment, including a cutting machine, a dust collection filter, a guide cone, and a connecting pipe connected to the bottom of the internal processing area of ​​the cutting machine. The first end of the connecting pipe is connected to the side of the dust collection filter. A dust collection pipe is installed on the top of the dust collection filter, and the end of the dust collection pipe is connected to a vacuum cleaner. A filter screen is installed in the middle of the dust collection filter cartridge. The filter screen is located between the end of the connecting pipe and the end of the dust collection pipe and is used to filter and separate coarse and fine plastic particles. The bottom of the dust collection filter cartridge is connected to the top of the guide cone, and a feeding group is installed at the bottom of the guide cone. A vibrating screen is located below the feeding group.

[0005] Furthermore, multiple electrically controlled valves are horizontally distributed at the bottom of the internal processing area of ​​the cutting machine, and each electrically controlled valve corresponds to a different position inside the cutting machine, and each of the electrically controlled valves is connected to the end of a connecting pipe.

[0006] Furthermore, the top of the guide cone is equipped with an upper cover plate, and the upper cover plate is fixedly equipped with an inner bracket. The upper cover plate has a material port in the middle that is connected to the bottom of the dust collection filter cartridge, and the inner bracket corresponding to the lower side of the material port is rotatably equipped with a backflow preventer, which is used to block the material port due to negative pressure when the connecting pipe is used for dust collection.

[0007] Furthermore, the feeding assembly includes an arc-shaped feeding plate horizontally installed at the bottom of the guide cone, a conveying screw is rotatably mounted on the inner side of the arc-shaped feeding plate, and a drive motor for driving the conveying screw to rotate is mounted on the outer side of the arc-shaped feeding plate.

[0008] Furthermore, the vibrating screen is provided with a feed hopper at the top, which is located below one end of the arc-shaped feeding plate. The vibrating screen is equipped with multiple discharge guides at different heights on its four side walls, and each discharge guide is equipped with a screen inside the vibrating screen.

[0009] Furthermore, the vacuum cleaner is equipped with a fine dust filter.

[0010] Compared with the prior art, the present invention has the following advantages: This invention has a simple and ingenious structure. It mainly involves connecting pipes to each cutting machine and using the negative pressure adsorption of a vacuum cleaner to allow dust and particles inside each cutting machine to enter the dust collection filter cartridge and be separated by the filter screen. The dust is sucked away and collected by the vacuum cleaner, while larger plastic particles fall downward into the guide cone for collection. The feeding group is activated as needed to allow the collected plastic particles to be fed into the vibrating screen below for vibration and redistribution for recycling according to particle size. Furthermore, during the vacuum cleaner's suction process, the feed inlet at the bottom of the dust filter cartridge can be blocked by the check baffle due to the vacuum cleaner's negative pressure suction, preventing most of the gas from entering through the guide cone and reducing the suction force of the connecting pipe. When it is necessary to feed the plastic particles inside the dust filter cartridge into the guide cone, simply stop the vacuum cleaner and the check baffle will rotate downwards and disengage from the feed inlet due to its own weight and the weight of the plastic particles, making it simple and convenient to use.

[0012] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0013] Please see Figures 1-6This utility model provides a technical solution for a plastic recycling and screening device for cutting equipment: It includes a cutting machine 1, a dust collection filter cartridge 3, a guide cone 4, and a connecting pipe 2 connected to the bottom of the internal processing area of ​​the cutting machine 1. The connecting pipe 2 is characterized in that its first end is connected to the side of the dust collection filter cartridge 3, and a dust collection pipe 31 is installed on the top of the dust collection filter cartridge 3. The end of the dust collection pipe 31 is connected to a vacuum cleaner 6, which contains a fine dust filter 61. Therefore, when the vacuum cleaner 6 is working, it can create a negative pressure adsorption effect in the connecting pipe 2, thus removing the plastic waste from the cutting machine. Plastic particles and dust deposited inside the machine 1 are sucked into the dust collection filter cartridge 3. Ten electrically controlled valves 21 are horizontally distributed at the bottom of the processing area inside the cutting machine 1, with each valve's end corresponding to a different position within the machine. All valves 21 are connected to the end of the connecting pipe 2. By controlling the opening and closing of different valves 21, specific locations inside the cutting machine 1 can be targeted for suction according to usage requirements, resulting in stronger suction force from each individual valve. Furthermore, a filter screen 30 is installed in the middle of the dust collection filter cartridge 3, located between the end of the connecting pipe 2 and the suction pipe. Between the ends of pipe 31, dust particles are drawn into the dust collection filter cartridge 3 through the connecting pipe 2. Finer dust particles can pass through the filter screen 30 and then enter the dust filter of the vacuum cleaner 6 for collection, while larger particles are filtered and fall downwards to the bottom of the dust collection filter cartridge 3. The bottom of the dust collection filter cartridge 3 is connected to the top of the guide cone 4. Since the top of the guide cone 4 is equipped with an upper cover plate 42, and the upper cover plate 42 is fixedly equipped with an inner support 43, the upper cover plate 42 has a material port 44 in the middle that communicates with the bottom of the dust collection filter cartridge 3, and the inner support 43 corresponding to the lower side of the material port 44 is rotatably equipped with a backflow preventer. 45. The check baffle 45 is made of plastic and is lightweight. When the connecting pipe 2 is vacuuming, the negative pressure of the vacuum filter cartridge 3 causes the check baffle 45 to rotate upward and block the feed inlet 44, preventing external gas from entering the vacuum filter cartridge 3 through the feed inlet 44 of the guide cone 4. This helps to prevent the suction force of the connecting pipe 2 from being reduced. When it is necessary to put plastic particles into the guide cone 4, simply turn off the vacuum cleaner 6 to remove the negative pressure from the entire vacuum filter cartridge 3. The check baffle 45 will then rotate downward and disengage from the feed inlet 44 due to its own weight and the weight of the plastic particles, allowing the plastic particles to fall into the guide cone 4. It is simple and convenient to use.

[0014] The bottom of the guide cone 4 is equipped with a feeding assembly 41. During use, the feeding assembly 41 includes an arc-shaped feeding plate 410 horizontally mounted at the bottom of the guide cone 4. A conveying screw 412 is rotatably mounted on the inner side of the arc-shaped feeding plate 410, and a drive motor 411 for driving the conveying screw 412 is mounted on the outer side of the arc-shaped feeding plate 410. Therefore, when it is necessary to send out the plastic granules stored inside the guide cone 4, the drive motor 411 can drive the conveying screw 412 to push the plastic granules outwards, allowing them to fall into the vibrating screen 5 below for vibration screening, thereby separating three different particle sizes of plastic granules. Specifically, the vibrating screen 5 has a feed hopper 51 at its top. The vibrating screen 5 has three discharge pipes 52 at different heights installed on its four side walls, and each discharge pipe 52 has a screening screen installed inside the vibrating screen 5. The feed hopper 51 is located below one end of the arc-shaped feeding plate 410. Therefore, after the plastic particles enter through the feed hopper 51, they can be vibrated and filtered by the screening screens. The plastic particles after each layer of vibration and filtration can be discharged outward from the corresponding discharge pipe 52. Only a material bucket needs to be placed below the discharge pipe 52 to collect the particles. Later, the three different particle sizes of plastic can be recycled and reused, thus completing the plastic particle screening work. This greatly improves the overall use effect and efficiency of the equipment and saves materials and production costs.
