DETAILED DESCRIPTION

[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0027] See also Figures 1 to 6The present invention provides the following technical solutions: A cleaning device for polyurethane material production, comprising a cleaning device body, the cleaning device body comprising a cleaning channel 7, a scrubbing mechanism 9, a driving mechanism 11 and a discharge assembly 12, the cleaning channel 7 is in an inclined state as a whole, and a feeding channel 6 is integrally formed at one end of the cleaning channel 7 at a high position, and a discharge channel 8 is integrally formed at one end of the cleaning channel 7 at a low position, a column 2 is welded to the bottom of the feeding channel 6 and the discharge channel 8, a bottom plate 1 is welded to the bottom of the column 2, a discharge box 3 is screwed to the surface of the bottom plate 1, a notch 14 is opened at the top of the cleaning channel 7, a scrubbing mechanism 9 is embedded in the inside of the notch 14, a drainage assembly 10 is arranged at the end of the cleaning channel 7, a driving mechanism 11 is welded at the end of the discharge channel 8, a discharge assembly 12 is embedded in the inner side of the driving mechanism 11, the top of the discharge assembly 12 is in an open state, and the inside of the discharge channel 8 is connected to the inside of the discharge assembly 12. The cleaning equipment for the production of polyurethane materials is used to clean the surface of polyurethane materials in particle form, and the cleaning methods include scrubbing, flushing, rubbing, etc.

[0028] When the present invention is used, the polyurethane granular material is directly and continuously fed from the top feed channel 6 to the inside through an external conveying device. The fed polyurethane granular material moves along the cleaning channel 7 toward the end, and finally enters the discharge channel 8, and is received and blocked by the discharge component 12 at the bottom of the discharge channel 8. The discharge component 12 is controlled by the driving mechanism 11 to move back and forth intermittently, so that the polyurethane granular material inside the discharge channel 8 can be intermittently filled into the inside of the discharge component 12 and discharged periodically. In this process, the polyurethane granular material inside the cleaning channel 7 will also move intermittently, and the washing mechanism 9 will also be started in this process. The washing mechanism 9 will rinse and scrub the polyurethane granular material in the intermittent moving state, and after the washing is completed, the polyurethane granular material accumulated at the rear end of the cleaning channel 7 will be rubbed and rolled by the first sponge pad 33 on the washing mechanism 9, and the water washed and adhered to the surface of the polyurethane granular material will be absorbed, and then the water absorbed can be squeezed out by the drainage component 10 to repeat the operation.

[0029] In this embodiment, the scrubbing mechanism 9 includes a sliding plate 30 and an electric telescopic rod 29, a brush 32 is attached to the middle of the bottom of the sliding plate 30, a first sponge pad 33 and a second sponge pad 34 are attached to the two ends of the bottom of the sliding plate 30, and the ends of the first sponge pad 33 and the second sponge pad 34 are aligned with the ends of the brush 32, an upper convex plate 31 is integrally formed on the top of the sliding plate 30, the end of the electric telescopic rod 29 is screwed to the surface of the upper convex plate 31, and the other end of the electric telescopic rod 29 is screwed to the surface of the feed channel 6, and a telescopic groove 13 is opened on the inner wall of the cleaning channel 7, and one end of the first sponge pad 33 and the sliding plate 30 are both embedded in the interior of the telescopic groove 13, and the upper convex plate 31 passes upward from the inside of the notch 14. Since the material is controlled to move intermittently and quantitatively, the scrubbing mechanism 9 with continuous operation can ensure that the cleaning of materials at different positions is always consistent, so that the materials put in can be subjected to equivalent scrubbing, rinsing and wiping processes, making the cleaning process more thorough and efficient.

[0030] Specifically, water is sprayed from the inside of the flushing cavity 15 toward the top screen 38 through the water pump 4 and the nozzle 5 at the bottom, and then the top of the screen 38, that is, the polyurethane granular material inside the cleaning channel 7 is flushed. At the same time, the electric telescopic rod 29 is started, and the entire upper convex plate 31 can be driven to move through the extension movement of the electric telescopic rod 29. The polyurethane granular material below can be scrubbed and rubbed with the help of the brush 32 at the bottom along the notch 14, and the cleaning performance is enhanced with the flushing effect. The process is continued, and the polyurethane granular material at each location can be discharged at the same time and the same path, so the final cleaning effect is also consistent. Most of the water generated during the flushing process will flow downward from the inside of the screen 38 again due to its own gravity and enter the flushing cavity 15 for discharge. The second sponge pad 34 is embedded in the inside of the telescopic groove 13 to ensure that the top of the cleaning channel 7 is always kept in a blocking state, providing space for the washing mechanism 9 to slide, while also preventing the internal polyurethane granular material from entering the inside of the telescopic groove 13.

[0031] In this embodiment, the drainage assembly 10 includes a drainage cavity 22 and an extrusion cavity 36. An extrusion plate 35 is welded to the bottom of the extrusion cavity 36. A drainage port 23 is provided at the bottom of the extrusion cavity 36. A guide channel 37 is provided at the bottom of the end of the extrusion cavity 36. The interior of the extrusion cavity 36 is connected to the interior of the drainage cavity 22 at the bottom through the guide channel 37 and the drainage port 23. A screen 38 is laid at the bottom of the cleaning channel 7. A flushing cavity 15 is provided at the bottom of the screen 38. A water pump 4 is placed on the inner side of the column 2. A nozzle 5 is connected to the surface of the water pump 4. The end of the nozzle 5 penetrates from the surface of the flushing cavity 15 to the inner side. A spray hole is provided at the top of the nozzle 5. The spray hole sprays the internal water flow toward the surface of the screen 38. The interior of the flushing cavity 15 and the surface of the drainage cavity 22 are both connected to a drainage pipe 24. By moving the scrubbing mechanism 9 and cooperating with the drainage assembly 10 at the rear end, wiping can be performed immediately after scrubbing and rinsing, and the moisture adsorbed by wiping can be squeezed out at a high frequency to avoid a large amount of moisture adhering to the surface of the polyurethane granular material, thereby improving the efficiency of subsequent drying.

[0032] Specifically, a first sponge pad 33 is attached to the bottom of the sliding plate 30. After being cleaned by the brush 32 in the middle, the polyurethane granular material moved to the first sponge pad 33 is absorbed with moisture. As the sliding plate 30 moves back and forth, once the first sponge pad 33 enters the extrusion cavity 36 at the rear, it will be extruded by the extrusion plate 35, so that the moisture absorbed by the first sponge pad 33 is squeezed out by the extrusion plate 35 and discharged into the drainage cavity 22 along the drainage port 23 at the bottom and the guide channel 37 at the rear end, and finally discharged along the drainage pipe 24 on the side of the drainage cavity 22.

[0033] In this embodiment, the driving mechanism 11 includes a motor 20 and a screw 21. The end side of the discharge channel 8 is integrally formed with a top baffle 16. The front end of the top baffle 16 is integrally formed with an end plate 19. Connecting frames 17 are welded on both sides of the top baffle 16. The bottom of the connecting frame 17 is plugged with a baffle 18. The output end of the motor 20 is inserted with a screw 21. The end of the screw 21 is embedded in the surface of the connecting frame 17 through a bearing. The number of the connecting frame 17 and the number of the baffle 18 are both two. The discharge assembly 12 includes a discharge trough 25 and an arc partition 26. The arc partition 26 is embedded in the middle position inside the discharge trough 25. The bottom of the discharge trough 25 is hinged with a flip support plate 28. The bottom of the flip support plate 28 is pressed on the top of the blocking rod 18, and there are two flip support plates 28. The top of the discharge groove 25 is against the bottom end of the discharge channel 8, and the length of the discharge groove 25 is twice the length of the discharge channel 8. The side of the discharge groove 25 is welded with a threaded sleeve 27, and the screw 21 passes through the inside of the threaded sleeve 27. The quantitative discharge of materials is controlled by the driving mechanism 11 and the discharge assembly 12, so that the materials inside the entire cleaning channel 7 present an effect of intermittent quantitative movement, thereby realizing the continuous feeding, cleaning, and discharge process, without the need for regular unified feeding and discharge processing, reducing the need for manual auxiliary operation.

[0034] Specifically, after starting the motor 20, the motor 20 drives the screw rod 21 to rotate, and the screw rod 21 cooperates with the threaded sleeve 27 to drive the entire telescopic slot 13 to slide, and finally the telescopic slot 13 is moved forward and backward along the bottom of the top baffle 16, thereby controlling the cavities at both ends of the telescopic slot 13 to alternately dock with the discharge channel 8 part, and when the interior of one of the discharge slots 25 is moved out of the bottom of the discharge channel 8, the bottom of the flip support plate 28 will be moved out of the range of the top rod, and without the support of the top rod, the bottom end of the flip support plate 28 can be tilted downward and opened, thereby automatically discharging the polyurethane granular material stored inside toward the discharge box 3 at the bottom, and in the process of the discharge slot 25 moving back and forth, the middle arc-shaped partition plate 26 has a semicircular structure at the top, so it can push the polyurethane granular material on the side during translation through its own arc surface, avoiding the problem of being stuck by the polyurethane granular material and unable to move normally.
