Description

Technical Field

[0001] This utility model relates to the field of roller press technology, and in particular to a mechanism for preventing clay adhesion to roller press rollers. Background Technology

[0002] A roller press (also known as an extruder or roller crusher) is a mechanical device designed based on the principle of high-pressure extrusion. Its core function is to apply continuous and high-intensity pressure to materials through two or more relatively rotating rollers, thereby achieving the crushing, compaction, shaping, or particle size adjustment of materials. It is widely used in industrial production for the processing of solid materials.

[0003] When a roller press extrudes materials, clay-like waste is often left on the roller skin. If not cleaned in time, it will stick to the roller skin. Currently, the roller skin is usually cleaned by workers scraping off the residual waste with a scraper, which is not only inefficient but also difficult to clean completely. In addition, the existing roller spacing adjustment is usually manually adjusted by rotating a screw, which has poor precision. Therefore, a mechanism to prevent clay from sticking to the roller skin of a roller press is needed. Summary of the Invention

[0004] The purpose of this invention is to provide a mechanism for preventing clay adhesion to the roller skin of a roller press, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mechanism for preventing clay adhesion to the roller skin of a roller press, comprising a base, a support plate and a hydraulic rod fixedly installed on the upper surface of the base, a support bar fixedly installed on one side of the top of the support plate, a sliding rod fixedly installed on the upper surface of the support bar, a support rod fixedly installed at the output end of the hydraulic rod, a slider fixedly installed on the top of the support rod, the sliding rod slidably installed inside the slider, an mounting strip fixedly installed on the slider, a fixed roller rotatably installed on the support plate, a movable roller rotatably installed on the mounting strip, a driving device fixedly installed on both the fixed roller and the movable roller, the fixed roller and the movable roller being driven by the driving device, and an anti-adhesion mechanism provided on the mounting strip.

[0006] Preferably, a limiting block is fixedly installed on the side of the support plate near the hydraulic rod, and the output end of the hydraulic rod is slidably installed inside the limiting block.

[0007] Preferably, the anti-adhesion mechanism includes a mounting frame fixedly mounted on the mounting strip, a support block fixedly mounted on the mounting frame, a rotating rod rotatably mounted inside the support block, and a turntable fixedly mounted at one end of the rotating rod.

[0008] Preferably, a gear is fixedly mounted on the rotating rod, and a rack is slidably mounted inside the mounting bracket, with the gear meshing with the rack.

[0009] Preferably, a first connecting block is fixedly installed on the top of the rack, one end of a first spring is fixedly installed on the bottom of the first connecting block, and the other end of the first spring is fixedly installed on the upper surface of the mounting bracket.

[0010] Preferably, a mounting block is sleeved at the bottom of the toothed rod, a connecting strip is fixedly mounted at the bottom of the mounting block, and a scraper is fixedly mounted at the bottom of the connecting strip.

[0011] Preferably, a plug rod is slidably installed within the mounting block, and a second connecting block is fixedly installed at the end of the plug rod away from the toothed rod. A second spring is fixedly installed at one end of the second connecting block near the toothed rod, and the other end of the second spring is fixedly installed on the mounting block.

[0012] Preferably, a slide bar is fixedly installed on the rack, and the slide bar is slidably installed in the mounting frame.

[0013] The beneficial effects of this utility model are:

[0014] In this invention, by setting up an anti-adhesion mechanism, rotating the turntable drives the gear to rotate, the gear to rotate, the gear to rotate, the gear to rotate, and the rack to rotate, which in turn moves the scraper. The scraper moves downward and approaches the rotating roller, thus scraping off the waste material remaining on the roller and preventing the waste material remaining on the roller from affecting its use.

[0015] In this invention, by setting up structures such as hydraulic rods, support rods, support bars, slide bars, and sliders, the hydraulic rod is activated, which drives the support rod to move. The movement of the support rod drives the moving roller to move, and the movement of the moving roller can adjust the distance between the fixed roller and the moving roller, making it convenient to extrude materials of different specifications.

[0021] 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. Example

[0022] like Figure 1-4 As shown, this embodiment provides a mechanism for preventing clay adhesion to the roller skin of a roller press, including a base 1. A support plate 2 and a hydraulic rod 3 are fixedly installed on the upper surface of the base 1. A support bar 5 is fixedly installed on one side of the top of the support plate 2. A slide bar 6 is fixedly installed on the upper surface of the support bar 5. A support rod 4 is fixedly installed at the output end of the hydraulic rod 3. A slider 7 is fixedly installed on the top of the support rod 4. The slide bar 6 is slidably installed in the slider 7. An installation strip 8 is fixedly installed on the slider 7. A fixed roller 9 is rotatably installed on the support plate 2. A movable roller 10 is rotatably installed on the installation strip 8. A driving device 11 is fixedly installed on both the fixed roller 9 and the movable roller 10. The fixed roller 9 and the movable roller 10 are driven by the driving device 11. An anti-adhesion mechanism 12 is provided on the installation strip 8. A limit block 13 is fixedly installed on the side of the support plate 2 near the hydraulic rod 3. The output end of the hydraulic rod 3 is slidably installed in the limit block 13.

[0023] Start the hydraulic rod 3, which drives the support rod 4 to move. The movement of the support rod 4 drives the slider 7 to move, and the movement of the slider 7 drives the moving roller 10 to move. The movement of the moving roller 10 can adjust the distance between the fixed roller 9 and the moving roller 10. The anti-adhesion mechanism 12 can scrape off the waste material remaining on the moving roller 10. The limit block 13 can limit the position of the output end of the hydraulic rod 3, so that it can only move along the vertical direction of the hydraulic rod 3.

[0024] In this embodiment of the utility model, specifically, the anti-adhesion mechanism 12 includes a mounting frame 121 fixedly mounted on the mounting strip 8, a support block 122 fixedly mounted on the mounting frame 121, a rotating rod 123 rotatably mounted inside the support block 122, a turntable 124 fixedly mounted at one end of the rotating rod 123, a gear 125 fixedly mounted on the rotating rod 123, a toothed rod 126 slidably mounted inside the mounting frame 121, the gear 125 meshing with the toothed rod 126, a first connecting block 127 fixedly mounted at the top of the toothed rod 126, one end of a first spring 128 fixedly mounted at the bottom of the first connecting block 127, the other end of the first spring 128 fixedly mounted on the upper surface of the mounting frame 121, a mounting block 129 sleeved at the bottom of the toothed rod 126, a connecting strip 1210 fixedly mounted at the bottom of the mounting block 129, and a scraper 1211 fixedly mounted at the bottom of the connecting strip 1210.

[0025] To remove residual waste material from the moving roller 10, the turntable 124 is rotated, which drives the rotating rod 123 to rotate. The rotation of the rotating rod 123 drives the gear 125 to rotate, and the rotation of the gear 125 drives the connecting bar 1210 to move. The movement of the connecting bar 1210 drives the scraper 1211 to move. The scraper 1211 moves downward and approaches the rotating moving roller 10, thereby scraping off the residual waste material from the moving roller 10.

[0026] In this embodiment of the utility model, a plug rod 1212 is slidably installed inside the toothed rod 126 and the mounting block 129. A second connecting block 1213 is fixedly installed at one end of the plug rod 1212 away from the toothed rod 126. One end of a second spring 1214 is fixedly installed on the side of the second connecting block 1213 close to the toothed rod 126. The other end of the second spring 1214 is fixedly installed on the mounting block 129.

[0027] To quickly assemble and disassemble the scraper 1211, pull the second connecting block 1213. The second connecting block 1213 drives the insert rod 1212 to move. When the insert rod 1212 moves out of the toothed rod 126, the mounting block 129 can be removed from the toothed rod 126, and the scraper 1211 can be replaced. After replacing the scraper 1211 with a new one, insert the new mounting block 129 into the toothed rod 126. Release the second connecting block 1213. Due to the setting of the second spring 1214, the second connecting block 1213 will move back to its original position, which will drive the insert rod 1212 to be inserted into the toothed rod 126, fixing the mounting block 129 on the toothed rod 126.

[0028] In this embodiment of the present invention, a slide bar 1215 is fixedly installed on the rack 126, and the slide bar 1215 is slidably installed in the mounting frame 121; the slide bar 1215 can limit the position of the rack 126, so that the rack 126 can only move up and down in the mounting frame 121 and not rotate in the mounting frame 121.

[0029] Working principle: In use, rotating the turntable 124 drives the rotating rod 123 to rotate, which in turn drives the gear 125 to rotate, which in turn drives the rack 126 to move, which in turn drives the mounting block 129 to move, which in turn drives the connecting strip 1210 to move, which in turn drives the scraper 1211 to move. The scraper 1211 moves downwards and approaches the rotating moving roller 10, thus scraping off the waste material remaining on the moving roller 10 and preventing residue from remaining on the moving roller 10. The remaining waste material affects the use of the moving roller 10. Loosening the turntable 124, due to the setting of the first spring 128, can drive the first connecting block 127 to move back to its original position, which in turn can drive the scraper 1211 away from the moving roller 10. Start the hydraulic rod 3, the hydraulic rod 3 drives the support rod 4 to move, the support rod 4 moves the slider 7 to move, the slider 7 moves the mounting strip 8 to move, the mounting strip 8 moves the moving roller 10 to move, and the movement of the moving roller 10 can adjust the distance between the fixed roller 9 and the moving roller 10, which is convenient for extruding materials of different specifications.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
