Description

Technical Field

[0001] This utility model relates to the field of water-based damping coating technology, specifically to a device for extruding and recycling water-based damping coating scraps. Background Technology

[0002] Because water-based damping coatings use water as a dispersion medium, they have very low VOC content and are safe and environmentally friendly. Therefore, water-based damping coatings have become the main application products in the field of vehicle body damping materials.

[0003] Based on NVH (noise, vibration, and harshness) performance requirements, water-based damping coatings need to be uniformly sprayed onto sheet metal in different locations and with different structures to achieve the designed damping effect. During normal construction, a pressure plate pump is usually used to squeeze the water-based damping coating in iron or stainless steel drums, and then transport it to the robot side through pipelines, and finally spray it onto different sheet metal parts of the vehicle body. However, the coating at the bottom of the drum cannot be completely squeezed out by the pressure plate pump, and there will be some residue. At present, the main methods for handling the scraps left at the bottom of the drum are centralized collection and liquid waste treatment, which is not conducive to material cost control, and improper treatment may cause environmental pollution. Alternatively, centralized collection, manual bag opening, and manual squeezing recycling can be used. This process is labor-intensive and time-consuming, which is not conducive to manufacturing cost control, and manual operation cannot completely squeeze out the scraps in the bag, resulting in material waste. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a water-based damping coating scrap extrusion recycling device.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A water-based damping coating scrap extrusion recycling device includes a movable frame, a rotatable lower pressure roller on the frame, scraper 1 and scraper 2 respectively located on both sides of the lower pressure roller on the frame, an upper pressure roller located above the lower pressure roller and movable, a sliding plate inclined downward to guide the top of the lower pressure roller on the frame, and a scraper 3 located on the side of the upper pressure roller facing the sliding plate and moving synchronously with the upper pressure roller.

[0007] Preferably, the frame is provided with an inclined guide plate and a flow deflector plate located below the lower pressure roller.

[0008] Preferably, a portion of the drainage plate is located below the slide plate, and the surface of the slide plate located above the drainage plate has a waist-shaped leakage hole.

[0009] Preferably, the frame is provided with a baffle located between the lower pressure roller and the upper pressure roller.

[0010] Preferably, the frame is provided with a bag collecting groove located below the lower pressure roller, and the bag collecting groove is located on the side of the lower pressure roller away from the slide plate.

[0011] Preferably, the frame is provided with a conveyor belt located at the end of the slide away from the lower pressure roller, and the frame is provided with a cutting cylinder located above the side of the conveyor belt near the slide, and the output end of the cutting cylinder is provided with a cutting blade.

[0012] Preferably, sensor one and sensor two are respectively installed on one side of the cutting cylinder and above the scraper three.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model can realize the transportation, bag breaking and squeezing of residual scraps from water-based damping coating construction, and is used for the continuous recycling and processing of scraps from water-based damping coatings. It effectively solves the problems of cumbersome manual squeezing process and incomplete scrap processing in the existing process.

[0015] 2. This utility model achieves precise bag breaking through the synergistic effect of sensors and cylinders, and the early intervention of squeezing effectively prevents leakage. The arrangement of scrapers on both sides of the lower pressure roller and one side of the upper pressure roller allows the coating that is squeezed and adhered to the pressure roller to be completely scraped off. The setting of the baffle between the upper and lower pressure rollers effectively prevents the coating from spreading to both sides and contaminating the equipment. The opposing installation of the diversion plate and the guide plate allows the coating to quickly collect at the discharge port. The opening of the waist-shaped hole on the surface of the slide plate accelerates the flow of coating towards the diversion plate and prevents accumulation. Attached Figure Description

[0023] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0024] like Figure 1 As shown, this utility model discloses a water-based damping coating scrap extrusion and recycling device, comprising a frame 1. A caster wheel 3 is mounted at the bottom of the frame 1. A pressure roller motor 2 is mounted on the frame 1 above the caster wheel 3. The output end of the pressure roller motor 2 is connected to a lower pressure roller 11 on the frame 1 via a chain drive. The operation of the pressure roller motor 2 drives the chain to rotate, thereby rotating the lower pressure roller 11. Scrapers 7 and 8 are arranged on the frame 1 on both sides of the lower pressure roller 11. A pressure roller cylinder 13 is mounted on the frame 1 above the lower pressure roller 11. An upper pressure roller 12 is mounted on the output end of the pressure roller cylinder 13 above the lower pressure roller 11. The operation of the pressure roller cylinder 13 drives the upper pressure roller 12... The pressure roller 12 is raised and lowered. A baffle 9 is set on the frame 1 between the lower pressure roller 11 and the upper pressure roller 12. The baffle 9 between the upper pressure roller 12 and the lower pressure roller 11 effectively prevents the paint from spreading to both sides and contaminating the equipment. A sliding plate 10 is set on the frame 1 to guide the top of the lower pressure roller 11 downward. The water-based damping paint scrap material bag is conveyed through the sliding plate 10. A scraper 3 14 is set on the frame 1 on the side of the upper pressure roller 12 facing the sliding plate 10 and fixed to the output end of the pressure roller cylinder 13. A sensor 2 15 is installed above the scraper 3 14. The arrangement of the scrapers on both sides of the lower pressure roller 11 and one side of the upper pressure roller 12 allows the paint that is squeezed and adhered to the pressure roller to be completely scraped off.

[0025] like Figure 1 As shown, the frame 1 has an inclined guide plate 4 and a guide plate 6 installed opposite each other below the lower pressure roller 11. The opposite installation of the guide plate 4 and the guide plate 6 allows the paint to quickly collect at the discharge port. The frame 1 is provided with a bag collection trough 5 located below the lower pressure roller 11, and the bag collection trough 5 is located on the side of the lower pressure roller 11 away from the slide plate 10. The bag collection trough 5 collects the material bags. Part of the guide plate 4 is located below the slide plate 10, and as shown... Figure 2 As shown, the surface of the slide plate 10 located above the diversion plate 4 has a waist-shaped leakage hole 101. The opening of the waist-shaped leakage hole 101 on the surface of the slide plate 10 accelerates the flow of the coating to the diversion plate 4 and prevents accumulation.

[0026] like Figure 1 As shown, a conveyor belt 19 is installed on the frame 1 at the end of the slide plate 10 away from the lower pressure roller 11. A cutter cylinder 17 is installed on the frame 1 above the side of the conveyor belt 19 near the slide plate 10, and a cutter 16 is installed at the output end of the cutter cylinder 17. A sensor 18 is installed on one side of the cutter cylinder 17. A control panel 20 is installed on one side of the frame 1. Commands are input through the control panel 20. The water-based damping coating scrap material bag is conveyed to the cutter 16 below the cutter 16 through the conveyor belt 19, and the cutter 16 is raised and lowered by the cutter cylinder 17 to perform the cutting work.

[0027] In use, turn on the main power supply and start the conveyor belt 19 and pressure roller motor 2 via the control panel 20. Place the water-based damping coating scrap material bag on the conveyor belt 19. As the conveyor belt 19 rotates, the material bag touches the sensor 18 signal, and the cutter cylinder 17 pushes the cutter 16 downward to cut the material bag. Then, the cutter cylinder 17 lifts up, driving the cutter 16 to rise and leave the material bag. The water-based damping coating scrap material bag slides into the slide plate 10. When the material bag touches the sensor 215 signal, the pressure roller cylinder 13 pushes the upper pressure roller 12 and scraper 314 downward. The upper pressure roller 12 makes contact with the lower pressure roller 11, which has scrapers 17 and 28 on both sides. The pressure roller motor 2, via the chain... The lower pressure roller 11 is driven to rotate, and at the same time, the lower pressure roller 11 drives the upper pressure roller 12 to rotate in the opposite direction through friction. The material bag enters between the upper pressure roller 12 and the lower pressure roller 11, and the water-based damping coating scraps are squeezed out. After the sensor 2 15 detects that the material bag has left, the pressure roller cylinder 13 is lifted, which drives the upper pressure roller 12 to rise. With the action of scraper 1 7, scraper 2 8 and scraper 3 14, the coating falls onto the diversion plate 4 and the guide plate 6, and the material bag is pushed into the collection trough 5. This realizes the transportation, bag breaking and squeezing of the residual scraps from the construction of water-based damping coatings. It is used for the continuous recycling and treatment of water-based damping coating scraps, which effectively solves the problems of cumbersome manual squeezing process and incomplete scrap treatment.

[0028] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
