A grinding and cooling integrated device for powder coating

Abstract

This invention relates to the field of combined processing technology and discloses an integrated grinding and cooling device for powder coatings, including a grinding hood and a cooler. The invention achieves gradual lifting of the push plate and progressive increase in the discharge gap through the conformal fit between the push plane of the guide block and the discharge slope. This allows materials to be screened and discharged in an orderly manner according to particle size from small to large, preventing the problem of compliant particle size powder being discharged directly without sufficient screening by the filter plate due to sudden opening and closing of the gap. This significantly reduces the unnecessary loss of qualified powder and significantly improves the overall utilization rate of materials. Furthermore, the gradual lifting and separation operation effectively reduces the problem of a single concentrated drop of material, avoiding the instantaneous accumulation of large quantities of material in a single area of ​​the grinding plate. This prevents excessive local material accumulation, uneven pressure, insufficient grinding, and grinding failure, ensuring uniform material distribution and balanced grinding force on the plate surface, and significantly improving powder screening accuracy and finished product uniformity.

Description

Technical Field

[0001] This invention belongs to the field of combined processing technology, and more specifically, relates to an integrated grinding and cooling device for powder coatings. Background Technology

[0002] Powder coatings, as a new type of environmentally friendly coating material, are widely used in many fields such as hardware and home appliances, automotive parts, building profiles, and machinery equipment due to their numerous advantages, including being solvent-free, pollution-free, having high coating utilization rates, and excellent coating performance. With the upgrading of quality in the coating industry and the continuous tightening of environmental policies, the market has placed higher demands on the particle uniformity, purity, molding stability, and finished product qualification rate of powder coatings. Grinding and cooling are the core processes in powder coating production. The fineness of grinding and the uniformity and timeliness of cooling directly determine the final performance and coating effect of the powder coating. Therefore, stable, efficient, and integrated grinding and cooling processing equipment is key to ensuring the large-scale, high-quality production of powder coatings.

[0003] Currently, mainstream powder coating grinding and cooling equipment on the market can realize the integrated operation of grinding and cooling processes. However, the supporting material feeding structure is mostly an instantaneous opening and closing operation mode. In actual production, the instantaneous opening and closing of the feeding gap will cause the operating gap to open and close suddenly. This makes it very easy for the qualified particle size powder mixed in the material to be discharged directly out of the equipment without being fully screened by the filter plate, resulting in a large amount of qualified powder being wasted and the material utilization rate being greatly reduced.

[0004] In view of this, the present invention is proposed. Summary of the Invention

The guide block has a pushing plane and a discharge slope. The pushing plane is adapted to the grinding plate. The discharge slope is used to drive the push plate to move to the filter plate. After the push plate moves to the filter plate, the push plate gradually moves upward, so that the material gradually separates from the push plate.

[0007] In a preferred embodiment of the present invention, a bracket is installed at the bottom of the grinding hood, and four support legs are installed at the bottom of the bracket. The four support legs are in a vertical state, and cross ribs are installed on two pairs of support legs located on the same side.

[0008] In a preferred embodiment of the present invention, a feeding pipe is installed on the grinding hood, the outlet of the feeding pipe is located above the grinding plate, a feeding hopper is installed at the inlet of the feeding pipe, the bottom of the feeding hopper is conical, a cover plate is installed on the top of the grinding hood, and a controller is installed on the outer wall of the grinding hood. The controller is used to control the start and stop of the drive assembly and the cooler.

[0009] In a preferred embodiment of the present invention, the driving assembly includes a driving motor, a support plate is mounted on the housing of the driving motor and the support plate is mounted on the side wall of the grinding hood, and a transmission shaft is mounted on the output end of the driving motor, the transmission shaft being connected to the rotation centers of the positioning plate and the filter plate respectively.

[0010] In a preferred embodiment of the present invention, a connecting shaft is installed at the rotation center of the grinding roller, a gear is installed at the end of the connecting shaft, a surrounding plate is installed on the outer side wall of the grinding plate, a rack is installed on the outer side wall of the surrounding plate, and the rack and the gear mesh with each other.

[0011] In a preferred embodiment of the present invention, a groove is provided on the outer wall of the enclosure, a slider is slidably mounted on the groove, a protective cover is mounted on the slider, the protective cover covers the outer wall of the rack and gear, the protective cover is rotatably connected to the connecting shaft, and the outer wall of the protective cover is installed on the inner wall of the grinding hood.

[0012] In a preferred embodiment of the present invention, a pull rod is installed on the connecting plate, a limit plate is installed at the end of the pull rod, a slide rod is also installed at the end of the connecting plate, the end of the slide rod is inserted into the plum blossom groove, a positioning cover is movably inserted into the outer wall of the pull rod, a slide seat is installed at the end of the positioning cover, guide rods are installed at both ends of the slide seat, and guide seats are installed at both ends of the guide rods, a support plate is installed at the end of the guide seat, and the support plate is placed inside the grinding hood.

[0013] In a preferred embodiment of the present invention, a guide block is installed at the bottom of the pallet, and a fixing plate is installed on the side wall of the guide block. The fixing plate is connected to the surface of the pallet by bolts.

[0014] In a preferred embodiment of the present invention, a timing frame is installed on the outer wall of the pull rod, and top rods are installed at both ends of the timing frame. The top rods are in a vertical state, and a ball bearing is rotatably installed at the end of the top rod, with the ball bearing in contact with the surface of the guide block.

[0015] In a preferred embodiment of the present invention, a baffle is slidably installed inside the positioning cover. The lower surface of the baffle is connected to the top of the pull rod. A compression spring is sleeved on the outer wall of the pull rod inside the positioning cover. One end of the compression spring is engaged with the baffle, and the other end of the compression spring is engaged with the bottom of the positioning cover. The compression spring is used to drive the end of the ball to fit against the end face of the guide block.

[0016] Compared with the prior art, the present invention has the following advantages: This invention utilizes the convex and concave surfaces of the guide block's pushing plane and the unloading ramp to achieve gradual lifting of the push plate and progressively increasing the material discharge gap. This allows materials to be screened and discharged in an orderly manner according to particle size, from small to large. It avoids the problem of compliant particle size powder being discharged directly without being fully screened by the filter plate due to sudden opening and closing of the gap, significantly reducing the unnecessary loss of qualified powder and significantly improving the overall material utilization rate. Furthermore, the gradual lifting and separation operation method can effectively reduce the problem of a large amount of material falling all at once, avoiding the problem of a large amount of material falling and accumulating in a single area of ​​the grinding plate. This prevents excessive accumulation of material in some areas, uneven pressure, insufficient grinding, and grinding failure, ensuring uniform material distribution and balanced grinding force on the plate surface. This significantly improves the powder screening accuracy and finished product uniformity, ensuring the smoothness and fineness of subsequent powder coating, and meeting the fine production requirements of high-end powder coatings.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention. Example

[0021] like Figures 1 to 9As shown, an integrated grinding and cooling device for powder coatings includes a grinding hood 1 and a cooler 10. A grinding plate 11 is rotatably mounted inside the grinding hood 1, and a filter plate 12 is mounted at the center of the grinding plate 11. The discharge position of the filter plate 12 corresponds to the feed position of the cooler 10. A drive assembly is also installed inside the grinding hood 1, which is used to drive the grinding plate 11 to rotate so that the material slides to the outside of the grinding plate 11 along the centrifugal force. A grinding roller 20 is rotatably mounted inside the grinding hood 1, located above the grinding plate 11 and used in conjunction with the grinding plate 11.

[0022] The output end of the drive assembly is also equipped with a positioning plate 24, and a plum blossom groove 25 is provided on the positioning plate 24. A connecting plate 27 is slidably installed inside the plum blossom groove 25, and a push plate 26 is installed on the connecting plate 27. The push plate 26 is attached to the side wall of the enclosure plate 16. The plum blossom groove 25 is used to guide the push plate 26 to move, so that the crushed material moves towards the filter plate 12. The end of the connecting plate 27 is slidably connected to the guide block 37. The guide block 37 is provided with a pushing plane 39 and a discharge slope 38. The pushing plane 39 is adapted to the grinding plate 11. The discharge slope 38 is used to drive the push plate 26 to move onto the filter plate 12. After that, the push plate 26 gradually moves upward, so that the material gradually separates from the push plate 26.

[0023] like Figures 1 to 9 As shown in the specific embodiment, a bracket 2 is installed at the bottom of the grinding hood 1, and four support legs 3 are installed at the bottom of the bracket 2. The four support legs 3 are in a vertical position, and two pairs of support legs 3 located on the same side are equipped with cross ribs 4. A mounting plate 9 is installed at the bottom of the support legs 3, and the mounting plate 9 has several pairs of mounting holes, which facilitate connection with the foundation. Through the reinforcement structure of the bracket 2, support legs 3 and cross ribs 4, the overall support strength and structural stability of the equipment can be greatly improved, effectively offsetting the vibration during equipment operation, preventing equipment deviation and shaking, and ensuring stable and continuous grinding operation.

[0024] like Figures 1 to 9 As shown, a feeding pipe 6 is further installed on the grinding hood 1. The outlet of the feeding pipe 6 is located above the grinding plate 11, and a feeding hopper 7 is installed at the inlet of the feeding pipe 6. The bottom of the feeding hopper 7 is conical. A cover plate 8 is installed on the top of the grinding hood 1, and a controller 5 is installed on the outer wall of the grinding hood 1. The controller 5 is used to control the start and stop of the drive components and the cooler 10. The conical structure of the feeding hopper 7, together with the feeding pipe 6, can achieve uniform and even feeding of raw materials, avoiding material accumulation and blockage. At the same time, the cover plate 8 can seal the inside of the grinding hood 1, and the controller 5 can realize the coordinated start and stop of various components of the equipment, improving the degree of automation control and the sealing performance of the operation. Example

[0025] The difference between the above embodiments and this embodiment is that: Figures 1 to 9As shown, the drive assembly includes a drive motor 14, a support plate 13 mounted on the housing of the drive motor 14, and the support plate 13 mounted on the side wall of the grinding hood 1. A drive shaft 15 is mounted on the output end of the drive motor 14, and the drive shaft 15 is connected to the rotation centers of the positioning plate 24 and the filter plate 12 respectively. By using a single drive motor 14 in conjunction with the drive shaft 15, the grinding plate 11, the filter plate 12, and the positioning plate 24 can rotate coaxially and synchronously. This results in high structural integration, good transmission synchronization, reduced energy consumption and failure points of multiple drive assemblies, and ensures a unified overall operating rhythm of the equipment.

[0026] like Figures 1 to 9 As shown in the specific embodiment, a connecting shaft 19 is installed at the rotation center of the grinding roller 20, and a gear 18 is installed at the end of the connecting shaft 19. A surrounding plate 16 is installed on the outer wall of the grinding plate 11, and a rack 17 is installed on the outer wall of the surrounding plate 16. The rack 17 and the gear 18 mesh with each other. By utilizing the meshing transmission of the rack 17 and the gear 18, the grinding roller 20 and the grinding plate 11 form a relative rotation structure, which performs bidirectional extrusion grinding on the centrifugally sliding material, greatly improving the fineness of material crushing and resulting in better grinding effect.

[0027] like Figures 1 to 9 As shown, further, a groove 22 is provided on the outer wall of the enclosure 16, and a slider 21 is slidably mounted on the groove 22. A protective cover 23 is mounted on the slider 21, covering the outer wall of the rack 17 and gear 18. The protective cover 23 is rotatably connected to the connecting shaft 19, and the outer wall of the protective cover 23 is installed on the inner wall of the grinding hood 1. Through the sliding fit of the slider 21 with the groove 22 and the protective cover 23, the meshing transmission area of ​​the rack 17 and gear 18 can be completely sealed, effectively preventing dust and debris from entering the transmission gap, avoiding wear and jamming of transmission components, and ensuring long-term stable operation of the transmission structure. Example

[0028] The difference between the above embodiments and this embodiment is that: Figures 1 to 9 As shown, a pull rod 30 is installed on the connecting plate 27, and a limit plate 31 is installed at the end of the pull rod 30. A slide rod 28 is also installed at the end of the connecting plate 27, and the end of the slide rod 28 is inserted into the plum blossom groove 25. A positioning cover 29 is movably inserted into the outer wall of the pull rod 30, and a slide seat 34 is installed at the end of the positioning cover 29. Guide rods 35 are installed at both ends of the slide seat 34, and guide seats 36 are installed at both ends of the guide rods 35. A support plate 13 is installed at the end of the guide seat 36, and the support plate 13 is placed inside the grinding hood 1. Through the multiple guiding and limiting structures of the slide rod 28, the plum blossom groove 25, the guide rod 35, and the guide seat 36, the sliding displacement of the pull rod 30 and the connecting plate 27 is precisely controllable, effectively avoiding the deviation and jamming of the pushing structure, and ensuring the precise and stable pushing action.

[0029] like Figures 1 to 9As shown, in a specific embodiment, a guide block 37 is installed at the bottom of the support plate 13, and a fixing plate 43 is installed on the side wall of the guide block 37. The fixing plate 43 is connected to the surface of the support plate 13 by bolts. A synchronization frame 40 is installed on the outer side wall of the pull rod 30. A top rod 41 is installed at both ends of the synchronization frame 40, and the top rod 41 is in a vertical state. A ball bearing 42 is rotatably installed at the end of the top rod 41, and the ball bearing 42 is in contact with the surface of the guide block 37. The guide block 37 is fixed by bolts to the fixing plate 43, which facilitates disassembly and maintenance. At the same time, the ball bearing 42 rolls with the guide block 37, replacing the traditional sliding friction, which greatly reduces operating wear and noise, and improves the smoothness and durability of the structural linkage.

[0030] like Figures 1 to 9 As shown, a baffle 32 is slidably installed inside the positioning cover 29. The lower surface of the baffle 32 is connected to the top of the pull rod 30. A compression spring 33 is sleeved on the outer wall of the pull rod 30 inside the positioning cover 29. One end of the compression spring 33 is engaged with the baffle 32, and the other end is engaged with the bottom of the positioning cover 29. The compression spring 33 is used to drive the end of the ball 42 to fit against the end face of the guide block 37. By continuously providing elastic preload through the compression spring 33, the ball 42 is ensured to always fit tightly against the surface of the guide block 37. This can adaptively compensate for structural gaps, ensuring that the pushing, lifting, and resetting actions are synchronized without lag, and guaranteeing the stability and consistency of the equipment's cyclic operation.

[0031] The implementation principle of the powder coating grinding and cooling integrated device of the present invention is as follows: First, the powder coating raw materials to be processed are received by the hopper 7. The raw materials are guided by a conical structure and fall at a uniform speed from the feed pipe 6 onto the grinding plate 11 inside the grinding hood 1. The entire device is stably supported by the bracket 2 and support legs 3. Cross ribs 4 enhance the structural stability of the support legs 3. The device is fixed to the foundation with the mounting holes on the mounting plate 9, ensuring that there is no shaking or displacement during the operation of the equipment. At the same time, the cover plate 8 on the top of the grinding hood 1 can seal the inside of the equipment to prevent dust from overflowing during the grinding process. The start-up, shutdown and operating parameters of the entire equipment are uniformly controlled by the controller 5 installed on the outer wall of the grinding hood 1, which can precisely control the coordinated working rhythm of the drive components and the cooler 10.

[0032] After the raw material falls onto the surface of the grinding plate 11, the drive motor 14 is started. Powered by the drive motor 14 fixed on the side wall support plate 13 of the grinding hood 1, the drive shaft 15 rotates continuously. The drive shaft 15 synchronously drives the grinding plate 11, filter plate 12, and positioning plate 24 to rotate coaxially. During the rotation of the grinding plate 11, centrifugal force is generated, which drives the material on the surface to slide towards the outer side plate 16 of the grinding plate 11. At the same time, the rack 17 on the outer side of the side plate 16 rotates synchronously with the grinding plate 11. Through meshing with the gear 18, it drives the connecting shaft 19 and the grinding roller 20 at the end to rotate, so that the grinding roller 20 and the grinding plate 11 form a relative rotational mating structure, which squeezes, grinds and crushes the centrifugally sliding material, realizing the fine grinding process of powder coating materials. The slider 21 is slidably mounted on the groove 22 of the enclosure plate 16. In conjunction with the protective cover 23 which is rotatably connected to the connecting shaft 19, it can fully cover the meshing area of ​​the rack 17 and the gear 18, effectively blocking dust and debris from entering the transmission structure, avoiding wear and jamming of transmission components, and ensuring the stability of transmission operation.

[0033] During the grinding and pulverizing operation, the positioning plate 24 rotates synchronously with the drive shaft 15. The plum blossom groove 25 on the positioning plate 24 provides precise guidance and positioning for the connecting plate 27, driving the connecting plate 27 to slide along the groove trajectory of the plum blossom groove 25. This, in turn, causes the push plate 26 at the end of the connecting plate 27 to move linearly back and forth against the inner wall of the surrounding plate 16 and toward the center of the grinding plate 11, thus achieving directional material pushing. The compression spring 33, which is sleeved on the outside of the pull rod 30 inside the positioning cover 29, abuts against the baffle 32 and the bottom of the positioning cover 29 at both ends, continuously outputting elastic thrust to press down the pull rod 30. This ensures that the ball bearings 42 at the ends of the vertically set top rods 41 on the synchronous frame 40 of the pull rod 30 are always in close contact with the surface of the guide block 37. The movement stroke and action posture of the push plate 26 are controlled by the profile trajectory of the guide block 37, effectively ensuring the synchronicity and operational stability of the pushing action.

[0034] As the ball bearing 42 rolls along the pushing plane 39 of the guide block 37, the pushing plane 39 remains horizontally supported, ensuring that the pusher plate 26 always slides smoothly against the surface of the grinding plate 11. This continuously pushes the fully ground powder material on the grinding plate 11 towards the filter plate 12 at the center, allowing the material to concentrate in the area of ​​the filter plate 12. This facilitates the filter plate 12 to screen and filter powder of the correct particle size. Fine powder passes through the filter plate 12 and is discharged, while coarse material remains on the surface of the grinding plate 11 for further grinding. As the positioning plate 24 continues to rotate, the ball bearing 42 gradually transitions from the pushing plane 39 to the unloading slope 38 along the trajectory of the guide block 37. Relying on the gradually tilting structure of the unloading slope 38, the top rod 41 and the synchronous frame 40 are gradually lifted upwards. This overcomes the elastic force of the compression spring 33, driving the pull rod 30 to move slowly upwards, thereby causing the connecting plate 27 to slide smoothly upwards along the groove of the plum blossom groove 25. At this time, the push plate 26 gradually rises synchronously with the connecting plate 27, and the distance between the push plate 26 and the grinding plate 11 and the material gradually increases, realizing the gradual separation of the push plate 26 and the material, rather than instantaneous separation. This gradual separation method allows the material feeding gap to gradually expand, allowing the screened material to be fed in an orderly manner according to the particle size from small to large. This can effectively reduce the problem of qualified powder mixed inside without passing through the filter plate and being directly discharged when the gap opens and closes instantaneously. This ensures that all qualified powder that should be screened is retained in the working area and continues to participate in grinding and crushing with the material, avoiding unnecessary loss of qualified material. At the same time, it ensures that all finished powder is accurately screened by the filter plate, greatly improving the uniformity of finished product screening and processing quality.

[0035] The qualified powder coating material, after being screened by filter plate 12, falls precisely from the discharge position of filter plate 12 into the feed position of the cooler 10 connected below. The cooler 10 used in this device is a JBF-42A powder air-cooled cooler specifically designed for powder coating grinding production lines. The specific structure of the cooler 10 is shown in the figure, and its specific working principle will not be elaborated here. After the material is cooled by the cooler 10, the grinding and cooling integrated continuous processing operation is finally completed. The entire device, through a precise mechanical linkage structure, realizes a continuous automated process of material grinding, screening, automatic feeding, and cooling, greatly improving the continuity of powder coating processing and the quality of finished products. Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
