Description

Technical Field

[0001] This utility model relates to the field of dust removal technology for plastic products, and in particular to a dust removal device for plastic products. Background Technology

[0002] During the production, processing, transportation, and storage of plastic products, their surfaces readily absorb dust, fibers, particulate matter, and static electricity, affecting their appearance and functional performance. Without effective dust removal, these contaminants can cause problems such as bubbles, delamination, and reduced adhesion during subsequent printing, painting, bonding, or assembly processes, severely impacting product yield and reliability. A clean surface helps improve the smoothness and aesthetics of the product, meeting customer quality standards.

[0003] In existing technologies, dust removal devices for plastic products typically use a combination of fans and roller brushes for cleaning. During the blowing process, the fans easily stir up dust, creating secondary dust that causes pollutants to re-adhere to or spread into the working environment, reducing the dust removal effect and affecting the air quality in the workshop. At the same time, the operating noise is relatively high, which is not good for the health of operators. Although the roller brush can help remove the attached substances, it is in direct contact with the surface of the plastic products and can easily scratch the product surface due to uneven pressure or excessively hard bristles, especially causing irreversible damage to high-gloss plastic parts. Utility Model Content

[0004] The purpose of this utility model is to provide a dust removal device for plastic products, so as to solve the problems mentioned in the background art, where the method of cleaning with a fan and a roller brush is used.

Detailed Implementation

[0017] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-6 This utility model provides an embodiment of a dust removal device for plastic products, including a base plate 1, a gantry 2 mounted on the base plate 1, a movable cleaning support 4 inside the gantry 2, a connecting component 3 mounted on the gantry 2, a water tank 10 on the base plate 1, a horizontal frame 41 for supporting plastic plates 101, a movable wheel 412 mounted on the horizontal frame 41, a support plate 51 for supporting the movable wheel 412 inside the water tank 10, a main water pipe 43 on the horizontal frame 41, a first spray pipe 431 connected to the side wall of the main water pipe 43 and one end of a connecting water pipe 433, and a second spray pipe 432 connected to the other end of the connecting water pipe 433, and the connecting component 3 including a conveying component with one end attached to the main water pipe 43, and a water delivery hose connected to the other end of the conveying component. By combining the gantry 2 with the mobile cleaning support 4, flexible and stable workpiece handling is achieved; the water tank 10 collects rinsing wastewater, which is convenient for environmental protection treatment. The water source is used to remove dust from the surface of the plastic sheet 101, avoiding the dust problem caused by dry dust removal, and reducing the risk of electrostatic adsorption.

[0019] Please see Figure 1-2 A further embodiment of this solution is as follows: a vertical frame 42 is installed on the horizontal frame 41 to provide support for the plastic sheet 101. The horizontal frame 41 is provided with a first stop 411 to prevent the plastic sheet 101 from sliding sideways, and the vertical frame 42 is provided with a second stop 421 to prevent the plastic sheet 101 from flipping over. The vertical frame 42 provides a vertical positioning reference, and the first stop 411 and the second stop 421 ensure the plastic sheet 101 is stable during cleaning, reducing the possibility of displacement. After the plastic sheet 101 is positioned on the frame, it is easy to perform subsequent spray rinsing to remove surface dust.

[0020] Please see Figure 2-3 A further solution based on this embodiment is as follows: Both sides of the vertical frame 42 can rely on plastic panels 101. A first water spray pipe 431 has a first water spray nozzle 4311 that sprays water onto the plastic panels 101 on both sides radially. A second water spray pipe 432 has a second water spray nozzle 4321 for spraying water onto the side of the plastic panel 101 away from the vertical frame 42. This design, relying on plastic panels 101 on both sides, significantly improves equipment utilization, allowing for the cleaning of two plastic panels 101 at a time, thus increasing production efficiency. The first water spray nozzle 4311 sprays from the inside, cleaning the side closest to the vertical frame 42, while the second water spray nozzle 4321 extends to the outside via a connecting water pipe 433, achieving double-sided rinsing and solving the problem of the plastic panels 101 being difficult to remove after cleaning in the water tank.

[0021] Please see Figure 2-3 A further embodiment of this solution is as follows: the main water pipe 43 includes a second annular block 44 at the top, on which a rubber ring 441 for sealing the conveying component and the main water pipe 43 is installed. The second annular block 44 and the rubber ring 441 form a dynamic sealing structure. When the conveying component is connected to the main water pipe 43, the rubber ring 441 is deformed under pressure to achieve a seal, effectively reducing high-pressure water leakage, ensuring stable water supply, and allowing the cleaning bracket 4 to move freely in a non-connected state.

[0022] Please see Figure 4-5 A further solution based on this embodiment is as follows: the top of the support plate 51 is provided with a limiting protrusion 52 for limiting the movement wheel 412, and the bottom of the support plate 51 is provided with a water passage hole 511 for connecting the water in the water tank 10. The limiting protrusion 52 prevents the movement wheel 412 from derailing or shifting, ensuring the accurate running trajectory of the cleaning bracket 4; the water passage hole 511 allows water to flow freely in all areas of the water tank 10, avoiding local water accumulation, which is conducive to centralized sewage treatment, improves environmental protection, and reduces water waste.

[0023] Please see Figure 4-5A further solution based on this embodiment is as follows: A mounting bracket 53 is installed inside the water tank 10, and a blocking cylinder 54 is installed on the mounting bracket 53. The output end of the blocking cylinder 54 is connected to a stop post 541 for blocking the cleaning bracket 4. A semi-circular groove 521 corresponding to the stop post 541 is provided on the limiting protrusion 52. When the moving wheel 412 is in contact with the stop post 541, the conveying component, the rubber ring 441, and the main water pipe 43 are in a concentric state. The blocking cylinder 54 drives the stop post 541 to extend and retract, thereby positioning the cleaning bracket 4. The semi-circular groove 521 and the stop post 541 cooperate to form a self-centering limit. The cleaning bracket 4 is manually pushed, and the cleaning bracket 4 stops at the same position each time, so that the conveying component is connected to the main water pipe 43, ensuring the reliability of the sealing connection. Even if there is a certain amount of positional deviation in the cleaning bracket 4, water can still be supplied to the cleaning bracket 4.

[0024] Please see Figure 3-4 A further embodiment of this solution is as follows: the conveying component includes a connecting pipe 33 that passes through the gantry 2. The connecting pipe 33 includes an annular block 331 at the bottom. The connecting assembly 3 includes a movable plate 31 that meshes with the connecting pipe 33. A push cylinder 32 is installed at the bottom of the movable plate 31 to drive the movable plate 31 to move up and down. A spring 332 is also sleeved on the connecting pipe 33 to push the annular block 331 to move down. By pushing the cylinder 32 to drive the movable plate 31 to move the connecting pipe 33 up and down, the automatic docking and separation of the conveying component and the main water pipe 43 is realized. The spring 332 provides a pushing force to the annular block 331 to ensure that the rubber ring 441 is fully compressed during docking to form a reliable seal. The threads of the connecting pipe 33 are easy to fit into the inner diameter of the water delivery hose to increase the pull-out resistance. The water delivery hose needs to be tied with a clamp at the position corresponding to the threads to increase the connection stability.

[0025] For another embodiment of the connection component 3, please refer to Figure 6 A further solution based on this embodiment is as follows: the connecting component 3 includes a bidirectional cylinder 34, and the conveying component includes an output rod 341 driven by the bidirectional cylinder 34. A threaded hole 3411 is machined inside the output rod 341. The bidirectional cylinder 34 drives the output rod 341 to achieve reciprocating telescopic motion, which is compact and responsive. The threaded hole 3411 can be used to connect the pipe 33 joint for quick connection or disassembly of the water delivery hose. The bidirectional cylinder 34 is also called a double-acting cylinder. Here, the bidirectional cylinder 34 uses an output rod 341. A piston is fixed at the outer diameter of the output rod 341. The piston moves back and forth in the cylinder chamber, thereby driving the output rod 341 to move back and forth. The moving principle of the bidirectional cylinder 34 is existing technology.

[0026] Working principle: A gantry 2 is erected on the base plate 1, and a movable cleaning support 4 is installed inside the gantry 2. The cleaning support 4 includes a horizontal frame 41 for supporting plastic plates 101. The horizontal frame 41 is equipped with casters 412, which roll on a support plate 51 inside the water tank 10, ensuring that the cleaning support 4 can move smoothly within the gantry 2. The top of the support plate 51 is provided with a limiting protrusion 52 to prevent the casters 412 from derailing or shifting, and the bottom is provided with a water passage hole 511, allowing water in the water tank 10 to flow freely, facilitating centralized wastewater treatment, improving environmental protection, and reducing water waste. A vertical... Frame 42 has plastic panels 101 placed on both its left and right sides. A first stop 411 prevents the plastic panels 101 from sliding sideways, and a second stop 421 prevents them from tipping over, ensuring the plastic panels 101 remain stable and do not shift during cleaning. A main water pipe 43 is installed on the horizontal frame 41 and connected to a first spray pipe 431 and a second spray pipe 432. The first spray pipe 431 has a first spray nozzle 4311 that extends radially through it, used to spray water onto the surface of the plastic panels 101 near the vertical frame 42 for cleaning. A connecting pipe 433 connects the main water pipe 43 to the second spray pipe 432. The second spray pipe 432 has a second spray nozzle 4321 for cleaning the plastic panels. Water is sprayed onto the surface of the plate 101 away from the vertical frame 42, thereby achieving double-sided rinsing of the plastic plate 101 placed on both sides. This solves the problem of difficulty in gripping the plate after washing in a traditional water tank due to the reduced friction coefficient caused by the water film. A connecting component 3 is installed on the gantry 2 to supply water to the main water pipe 43 when the cleaning bracket 4 is in position. The connecting component 3 includes a conveyor, one end of which is attached to the main water pipe 43 to achieve water supply connection, and the other end is connected to an external water supply hose. The top of the main water pipe 43 is provided with an annular block 44, on which a rubber ring 441 is installed to form a seal during docking and reduce water leakage. The first embodiment of the conveyor includes a connecting component that passes through the gantry 2. The connector 33 has an annular block 331 at its bottom. The connecting assembly 3 also includes a movable plate 31 that is connected to the connecting pipe 33 via a rack and pinion. The movable plate 31 has a push cylinder 32 at its bottom. The push cylinder 32 drives the movable plate 31 to move up and down, causing the connecting pipe 33 to rise and fall, so that it can connect or separate from the main water pipe 43. At the same time, a spring 332 is fitted on the connecting pipe 33. The spring 332 pushes the annular block 331 downward, so that the connecting pipe 33 remains stable during the descent and ensures that the rubber ring 441 is fully compressed to achieve a reliable seal. The outer wall of the connecting pipe 33 has threads that can be matched with the end of the water delivery hose and locked by a clamp to increase the connection stability.The second embodiment of the connecting component 3 is a bidirectional cylinder 34, which drives the output rod 341 to reciprocate axially. The output rod 341 has a threaded hole 3411 machined inside for connecting the pipe 33 connector, facilitating quick connection or disconnection of the water supply hose. This bidirectional cylinder 34 is a single-rod double-acting cylinder, with its internal piston fixed at the outer diameter of the output rod 341. Under air pressure, it reciprocates within the cylinder chamber, causing the output rod 341 to extend and retract. This is existing technology. A mounting bracket 53 is installed inside the water tank 10, on which a blocking cylinder 54 is mounted. The output end of the blocking cylinder 54 is connected to a stop post 541. When the cleaning bracket 4 is manually pushed to the cleaning station, the blocking cylinder 54 activates, causing the stop post 541 to extend, thus achieving... The positioning of the cleaning bracket 4 is ensured to maintain a roughly consistent stopping position each time, thereby accurately connecting the conveyor to the main water pipe 43. Even with slight positional deviations in the cleaning bracket 4, reliable docking can be achieved, guaranteeing continuous water supply and sealing. The entire device uses water as the cleaning medium, forming a flowing water film on the surface of the plastic plate 101 through spraying, effectively removing dust particles. After cleaning, the entire cleaning bracket 4, along with the cleaned plastic plate 101, can be pushed into the drying workshop. The corresponding water supply output, water circuit on / off, and air circuit connection are all existing technologies, and their working principles will not be elaborated here. The bidirectional cylinder 34 needs to be customized by a supplier to match the output rod 341 that can engage the pipe connector.
