Technical Field
[0001] This utility model relates to the field of coating production technology, and more specifically, to an anti-sticking pressure roller structure for a powder coating tablet press. Background Technology
[0002] Powder coating tablet presses are mainly used for pressing and forming tablets after the coating has been melted. They work in conjunction with a cooling conveyor belt to achieve rapid cooling and forming after pressing. The main structure consists of a feeding device, a material level control device, a pair of rollers (one fixed roller and one moving roller), a transmission device (motor, pulley, gear shaft), a hydraulic system, and a transverse leak-proof device. One roller is a fixed roller supported on a bearing; the other is a moving roller. The moving roller applies pressure to the material layer. The two rollers rotate in opposite directions at the same speed. Sealing devices (heart-shaped plates) at both ends of the rollers prevent material from being discharged from the transverse gap under high pressure.
[0003] After powder coatings are melted and pressed into tablets using a pressure roller structure, they are susceptible to adhesion to the pressure roller structure due to various uncertainties such as temperature and material properties. Currently, it is difficult to completely prevent this adhesion, thus requiring rapid processing of the adhered material. When powder coatings tend to stick to the sides during extrusion, some existing technologies simply clean the adhered material from the sides and place it in a waste bin for later use. This method fails to promptly identify whether the adhered material is suitable for further processing, resulting in material waste and reduced production efficiency. Therefore, we propose an anti-sticking pressure roller structure for powder coating tableting machines. Utility Model Content
[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a non-sticking roller structure for a powder coating tablet press, so as to solve the technical problem that when the side of the current press roller sticks, the stuck material is directly cleaned up and no longer used in time.
[0005] To solve the above technical problems, this utility model provides the following technical solution: a powder coating tablet press anti-sticking roller structure, including an anti-sticking structure, the anti-sticking structure including a U-shaped plate and a curved plate installed at one end of the U-shaped plate, an elastic adjuster, an oil roller, a scraper and an auxiliary positioning roller are respectively installed on the curved plate from top to bottom, the oil roller and the scraper are detachably connected to the curved plate, a linkage plate and a side adjustment plate with adaptive vertical distance adjustment function are also installed between the auxiliary positioning roller and the curved plate, the left and right sides of the linkage plate are connected to the side adjustment plate, a linkage shaft is installed between the top of the linkage plate and the curved plate, the oil roller includes a roller frame and a roller body installed on the curved plate, the roller body has a plurality of grooves evenly opened for installing oil injection sponges, the roller frame and the roller body are rotatably connected, a front cover plate is installed at the bottom of the curved plate, the front cover plate has a horizontal groove, and a guide wheel is installed in the horizontal groove.
[0006] Preferably, the U-shaped plate on the anti-stick structure is connected to a frame at the end away from the curved plate, and an output belt and a pressure roller are also installed on the frame. The elastic adjuster on the curved plate is in contact with the pressure roller.
[0007] Preferably, an adjusting shaft is installed between the U-shaped plate and the curved plate. The elastic adjuster includes two spring tubes and a rubber wheel installed at one end of the spring tubes. The end of the spring tube away from the rubber wheel is connected to the curved plate, and the rubber wheel is in contact with the pressure roller.
[0008] Preferably, the scraper consists of an insert plate connected to the curved plate at its bottom and a metal blade mounted on the insert plate. The front end of the metal blade is designed to be inclined, and a triangular groove is opened at the bottom of the metal blade. A collection point for collecting material from the side of the pressure roller is provided between the bottom of the scraper and the curved plate.
[0009] Preferably, the outer wall of the auxiliary positioning roller is made of the same material as the outer wall of the pressure roller, the linkage plate and the curved plate are installed with a detachable structure, and a semi-circular limiting ring is installed at the bottom rear side of the curved plate, with the end of the limiting ring away from the curved plate contacting the rear side of the linkage plate.
[0010] Preferably, the front cover is located at the bottom of the collection point and cooperates with the collection point. The front cover has a gap with the linkage plate under normal pressure. The guide wheel on the front cover is rotatably connected to the front cover. The front cover includes a first curved part, a second curved part and a third curved part from top to bottom. The transverse groove is located between the second curved part and the third curved part. The first curved part is an arc shape with an outward curve. The second curved part is an arc shape with an inward curve. The third curved part is an arc shape with an inward curve and an arc shape with the opposite curvature direction to the second curved part. The end of the third curved part corresponds to the auxiliary positioning roller. Side guide plates for guiding materials are installed on both sides of the front cover.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. This utility model, through the design of a curved plate structure, installs a linkage rotating shaft at the bottom of the curved plate, which drives the linkage plate to rotate. At the same time, the auxiliary positioning roller at the bottom of the side adjustment plate presses down. After the auxiliary positioning roller presses down and comes into contact with the material adhering to the side, it squeezes it again, so that it is still on the output belt for material correction. The material that is successfully corrected can continue to be output for subsequent segmentation and use, and the material that fails to be corrected can be collected and reused. This solves the technical problem of the current pressure roller machine directly cleaning up the material adhering to the side and not using it in time.
[0013] 2. This utility model, through the design of a front baffle structure, allows materials to pass through the first and second bends before falling onto the output belt. After passing through the transverse groove, the materials come into contact with the guide wheel, are adjusted to fall onto the third bend, and then fall onto the side of the auxiliary positioning roller before falling onto the output belt. This guides the falling of materials from the side, preventing direct falling and accumulation, and further improves the material correction efficiency and success rate.
[0014] 2. This utility model also designs a scraper structure. When the material on both sides of the pressure roller is stuck together, the elastic adjuster installed on the top of the curved plate will cause the scraper at the bottom to lift up and stick to the pressure roller when it comes into contact with the pressure roller. This will hang up and clean the stuck material on both sides of the pressure roller. Then, the material will fall down through the collection point and onto the output belt through the baffle. This will achieve secondary squeezing by the auxiliary positioning roller. The scraper structure is designed to be detachable, which is convenient for cleaning the stuck material in different areas.

Detailed Implementation
[0022] like Figures 1 to 6 As shown, this utility model relates to an anti-sticking roller structure for a powder coating tablet press, including an anti-sticking structure 200. The anti-sticking structure 200 includes a U-shaped plate 210 and a curved plate 230 installed at one end of the U-shaped plate 210. An elastic adjuster 270, an oil roller 250, a scraper 260, and an auxiliary positioning roller 243 are respectively installed on the curved plate 230 from top to bottom. The oil roller 250 and the scraper 260 are detachably connected to the curved plate 230. A linkage plate 241 with adjustable vertical distance is also installed between the auxiliary positioning roller 243 and the curved plate 230. The side adjustment plate 242 is adjustable. The left and right sides of the linkage plate 241 are connected to the side adjustment plate 242. A linkage shaft 240 is installed between the top of the linkage plate 241 and the curved plate 230. The oil roller 250 includes a roller frame and a roller body installed on the curved plate 230. The roller body has a plurality of grooves evenly opened for installing oil sponges. The roller frame and the roller body are rotatably connected. A front cover plate 232 is installed at the bottom of the curved plate 230. A transverse groove 239 is opened on the front cover plate 232. A guide wheel 234 is installed in the transverse groove 239.
[0023] This utility model, through the design of a curved plate 230 structure, installs a linkage rotating shaft 240 at the bottom of the curved plate 230. When the linkage plate 241 rotates, the auxiliary positioning roller 243 at the bottom of the side adjustment plate 242 presses down. After the auxiliary positioning roller 243 presses down and contacts the material adhering to the side, it squeezes it again, so that it is still on the output belt 110 for material correction. The material that is successfully corrected can continue to be output for subsequent segmentation and use, and the material that is not corrected can be collected and reused. This solves the technical problem of the current pressure roller 120 machine directly cleaning up the material that is stuck to the side and not using it in time.
[0024] This utility model also incorporates a scraper 260 structure. When materials adhere to both sides of the pressure roller 120, the elastic adjuster 270 installed on the top of the curved plate 230 contacts the pressure roller 120, causing the scraper 260 at the bottom to lift up and adhere to the pressure roller 120, thus cleaning the adhered materials on both sides of the pressure roller 120. The materials then fall through the collection point 233 and down the baffle onto the output belt 110, thereby achieving secondary squeezing by the auxiliary positioning roller 243. The scraper 260 structure is detachable, facilitating cleaning operations for different areas.
[0025] Specifically, the U-shaped plate 210 on the anti-stick structure 200 is connected to a frame 100 at the end away from the curved plate 230. An output belt 110 and a pressure roller 120 are also installed on the frame 100. The elastic adjuster 270 on the curved plate 230 is in contact with the pressure roller 120. The frame 100, the output belt 110, and the pressure roller 120 constitute the overall structure of the pressure roller 120 in the prior art, realizing the operation of material pressing. During use, the elastic adjuster 270 keeps its output end in contact with the pressure roller 120 through the internally installed spring structure.
[0026] Furthermore, an adjusting shaft 220 is installed between the U-shaped plate 210 and the curved plate 230. The elastic adjuster 270 includes two spring tubes and a rubber wheel installed at one end of the spring tubes. The end of the spring tube away from the rubber wheel is connected to the curved plate 230, and the rubber wheel is in contact with the pressure roller 120. The adjusting shaft 220 allows the curved plate 230 to adjust its angle according to the state of the pressure roller 120. The curved structure of the curved plate 230 is horizontal to the pressure roller 120 as a whole, and its curvature is the same as that of the pressure roller 120, which facilitates the contact and movement of the top rubber wheel and improves the stability of relative movement.
[0027] It is worth noting that the scraper 260 consists of an insert plate connected to the curved plate 230 at its bottom and a metal blade mounted on the insert plate. The front end of the metal blade is designed to be inclined, and a triangular groove is opened at the bottom of the metal blade. A collection point 233 for collecting material from the side of the pressure roller 120 is provided between the bottom of the scraper 260 and the curved plate 230. The insert plate and the curved plate 230 are detachably connected, which facilitates the cleaning of materials adhering to different areas. The inclined design of the front end of the blade can achieve close contact with the pressure roller 120 for scraping. The triangular groove at the bottom, together with the inclined design of the scraper 260, enables the scraped material to be quickly separated from the scraper 260, reducing the occurrence of material adhering to the scraper 260.
[0028] It is worth mentioning that the outer wall of the auxiliary positioning roller 243 is made of the same material as the outer wall of the pressure roller 120. The linkage plate 241 and the curved plate 230 are installed with a detachable structure. A semi-circular limiting ring 231 is installed on the rear bottom of the curved plate 230. The end of the limiting ring 231 away from the curved plate 230 is in contact with the rear side of the linkage plate 241. The same material ensures a consistent coefficient of friction and wear resistance, reducing slippage or damage caused by material differences. At the same time, the semi-circular limiting ring 231 can effectively adjust and fix the position of the linkage plate 241, improve stability, and facilitate position restriction of the linkage plate 241.
[0029] It is worth noting that the front cover 232 is located at the bottom of the collection point 233 and cooperates with the collection point 233. A gap is left between the front cover 232 and the linkage plate 241 under normal pressure. The guide wheel 234 on the front cover 232 is rotatably connected to the front cover 232. The front cover 232 includes a first curved portion 236, a second curved portion 237, and a third curved portion 238 from top to bottom. The transverse groove 239 is located between the second curved portion 237 and the third curved portion 238. The first curved portion 236 is an outwardly curved arc, the second curved portion 237 is an inwardly curved arc, and the third curved portion 238 is an inwardly curved arc opposite to the curvature of the second curved portion 237. The end of the third curved portion 238 connects with the auxiliary positioning roller 2. Correspondingly, side guide plates 235 for guiding materials are installed on both sides of the front cover plate 232. The front cover plate 232 is installed to prevent scraped materials from falling into the gap between the linkage plate 241 and the curved plate 230 after falling into the collection point 233, causing rotational obstruction. At the same time, it prevents material accumulation. The guide wheel 234 installed on the front cover plate 232 can ensure that after the scraped materials fall, they can pass through the cross groove 239 and fall into the side of the auxiliary positioning roller 243 through the third curved part 238 for secondary auxiliary positioning and falling, so as to achieve a relatively flat operation. At the same time, the side guide plate 235 can effectively prevent tilting when falling onto the front cover plate 232, reduce the occurrence of material falling and piling, and achieve the purpose of reuse.
[0030] Working Principle: This embodiment provides an anti-sticking pressure roller structure for a powder coating tablet press. During use, the pressure roller 120 rotates to compress the material into tablets, which are then output via the output belt 110. Material adheres to both sides of the pressure roller 120. A curved plate 230 connected to one end of the U-shaped plate 210 adaptively adjusts its angle via an adjusting shaft 220. At this time, the elastic adjuster 270 is in contact with the pressure roller 120, and the angle of the curved plate 230 is relatively fixed. Simultaneously, the scraper 260 at the bottom is in contact with the pressure roller 120, scraping away the adhered material. The scraped material then passes through the collection point 233 and the front cover plate. 232 falls onto the bottom output belt 110. Specifically, after the scraped material falls and passes through the collection point 233, it passes through the first bend 236 and the second bend 237 by inertia, and then contacts the guide wheel 234 when it passes through the transverse groove 239. After being adjusted to fall into the third bend 238, it falls into the side of the auxiliary positioning roller 243 and then falls onto the output belt 110. Then, the auxiliary positioning roller 243 rotates to perform a second pressing operation on the fallen material. The spring structure installed on the side adjustment plate 242 applies pressure to the auxiliary positioning roller 243 to press it. After passing through the output belt 110, it can be judged whether it is usable for screening.
[0031] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
