Description

Technical Field

[0001] This utility model relates to the field of roller coating machine technology, specifically to a lifting and adjusting mechanism for a roller coating machine. Background Technology

[0002] Roller coating uses a rotating roller as a carrier for the coating material. The coating material forms a wet film of a certain thickness on the surface of the roller, and then the roller contacts the object being coated during rotation, thus applying the coating material to the surface of the object. Roller coating is suitable for flat objects and is widely used in coating metal sheets, plywood, cloth, and paper.

[0003] Publication number CN219631747U discloses a roller coating machine that uses two coating components working in tandem to coat materials. The coating components can overlap to achieve coatings of various thicknesses, or they can be distributed at different locations on the material for simultaneous coating, allowing for adjustments in different situations. However, this patent still has the following problems in practical use:

[0004] The inconvenience of adjusting and cleaning the surface of the board means that impurities on the surface of the board will affect the coating effect during the coating process. This will result in poor coating in some areas of the board due to impurities, thus affecting the quality of the roller coating.

[0005] A lifting and adjusting mechanism for a roller coating machine is proposed to address the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide a lifting and adjusting mechanism for a roller coating machine to solve the problem mentioned in the background art that it is currently inconvenient to adjust and clean the surface of the board, which leads to impurities on the surface of the board affecting the coating effect during coating, resulting in poor coating effect in some areas of the board due to impurities, and thus affecting the quality of the roller coating.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a lifting and adjusting mechanism for a roller coating machine, comprising a base plate and a connecting plate installed on the top of the base plate, wherein two connecting plates are symmetrically arranged;

[0008] A rubber roller is rotatably connected between the upper parts of the base plates, and a slider is slidably connected inside the connecting plate. A support roller is rotatably connected between the sliders. An electric push rod is installed inside the connecting plate and is fixedly connected to the slider. The rubber roller and the support roller are driven by two sets of first motors respectively.

[0009] Also includes:

[0010] The top of the base plate is provided with a cleaning adjustment assembly, which includes a mounting frame, and a mounting plate is fixedly connected to the top of the mounting frame. A second motor is mounted on one side of the mounting plate, and a round block is rotatably connected to one side of the mounting plate. The output end of the second motor is fixedly connected to the round block.

[0011] Among them, the bottom of the round block is fixedly connected to a toothed block, the top of the mounting bracket is fixedly connected to a square plate, the front of the square plate is fixedly connected to a first spring, and the front of the first spring is fixedly connected to a fixing block.

[0012] The fixed block is fixedly connected to the square plate by a first telescopic rod, and the front of the fixed block is fixedly connected to a rack, which meshes with the rack.

[0013] Preferably, the mounting bracket has an internal sliding connection to a slide plate, and the slide plate has an internal mounting groove.

[0014] Preferably, a first brush bristle is fixedly connected to the top inner side of the mounting groove, and a threaded rod is connected to the internal thread of the slide plate.

[0015] Preferably, the top of the threaded rod is rotatably connected to a second brush bristle, and a second telescopic rod is fixedly connected between the second brush bristle and the slide plate.

[0016] Preferably, the first bristles correspond to the second bristles.

[0017] Preferably, the inner side of the mounting frame is provided with a lifting and conveying assembly, the supporting lifting and conveying assembly includes a support plate, multiple support plates are symmetrically arranged, a belt structure is installed between the support plates, and a hydraulic rod is installed on one side of the support plate.

[0018] Preferably, a limiting plate is fixedly connected to the top of the hydraulic rod, and multiple rotating wheels are symmetrically rotated inside the limiting plate.

[0019] Compared with the prior art, the beneficial effects of this utility model are: the lifting and adjusting mechanism of this roller coating machine facilitates the cleaning of the surface of the sheet material, thereby improving the roller coating quality of the sheet material, and can also be adjusted and cleaned according to the specifications of the sheet material. The specific details are as follows:

[0020] 1. The second motor drives the circular block to rotate, which in turn drives the toothed block to move in a circular motion. The toothed block then drives the rack to move, while the first spring is stretched. When the toothed block reaches a certain distance, it disengages from the rack, and the first spring rebounds, causing the rack to reset. When the toothed block reaches a certain distance again, it re-engages with the rack. The rack repeats the above actions continuously, moving back and forth. This movement drives the slide plate to move back and forth, cleaning both sides of the board simultaneously. This surface cleaning is performed before roller coating, improving the quality of the roller coating. Next, the threaded rod is rotated and lowered, causing the second brush bristles to descend. This allows for adjustment of the second brush bristle position to accommodate surface cleaning of boards of different widths.

[0021] 2. When the sheet material to be coated is placed on the limiting plates on both sides, i.e., the rollers, the hydraulic rod is activated. The sheet material is then passed between the first and second brush bristles, causing the hydraulic rod to lift the limiting plates. The limiting plates then lift the sheet material, and the top of the sheet material rests against the belt structure. The belt structure is then activated to transport the sheet material. During the transport process, the surface of the sheet material is cleaned by the cleaning and adjustment components. Finally, the sheet material is coated with adhesive by the rubber rollers and idler rollers, thus allowing for the adjustment and fixed transport of sheet materials of different specifications.

[0029] 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.

[0030] Please see Figure 1 - Figure 6 The present invention provides the following technical solution:

[0031] A lifting and adjusting mechanism for a roller coating machine includes a base plate 1 and a connecting plate 2 mounted on the top of the base plate 1, with two connecting plates 2 symmetrically arranged. A rubber roller 201 is rotatably connected to the upper part of the base plate 1, and a slider 202 is slidably connected inside the connecting plate 2. A support roller 203 is rotatably connected between the sliders 202. An electric push rod 205 is installed inside the connecting plate 2 and is fixedly connected to the slider 202. The rubber roller 201 and the support roller 203 are driven by two sets of first motors 204. A cleaning and adjusting assembly 4 is provided on the top of the base plate 1. The cleaning and adjusting assembly 4 includes a mounting frame 401, and the top of the mounting frame 401 is fixedly connected to... A mounting plate 402 is provided, and a second motor 403 is mounted on one side of the mounting plate 402. A circular block 404 is rotatably connected to one side of the mounting plate 402, and the output end of the second motor 403 is fixedly connected to the circular block 404. A toothed block 405 is fixedly connected to the bottom of the circular block 404. A square plate 406 is fixedly connected to the top of the mounting bracket 401, and a first spring 407 is fixedly connected to the front of the square plate 406. A fixing block 408 is fixedly connected to the front of the first spring 407. A first telescopic rod 409 is fixedly connected between the fixing block 408 and the square plate 406, and a rack 410 is fixedly connected to the front of the fixing block 408. Figure 3 , 5As shown in Figure 6, the second motor 403 drives the circular block 404 to rotate, which in turn drives the toothed block 405 to move in a circular motion. The toothed block 405 then drives the rack 410 to move, while the first spring 407 is stretched. When the toothed block 405 moves to a certain extent, it disengages from the rack 410, and the first spring 407 rebounds, causing the rack 410 to reset. When the toothed block 405 moves to a certain extent, it re-engages with the rack 410. Thus, the rack 410 will continuously repeat the above actions, and the rack 410 will move back and forth, while the rack 410 and the toothed block 405 are engaged and connected.

[0032] The mounting bracket 401 has an internal sliding connection to a slide plate 411, and the slide plate 411 has an internal mounting groove 412. A first brush bristle 413 is fixedly connected to the top inner side of the mounting groove 412. A threaded rod 414 is threadedly connected to the inside of the slide plate 411, and a second brush bristle 416 is rotatably connected to the top of the threaded rod 414. A second telescopic rod 415 is fixedly connected between the second brush bristle 416 and the slide plate 411. Figure 3-5 As shown, the slide plate 411 cleans both sides of the board simultaneously, allowing the board to be surface-cleaned before roller coating, thereby improving the quality of the board's roller coating. Next, the threaded rod 414 is rotated and lowered, which in turn causes the second brush bristle 416 to descend, allowing the position of the second brush bristle 416 to be adjusted up and down to accommodate surface cleaning of boards of different widths. The first brush bristle 413 corresponds to the second brush bristle 416.

[0033] The inner side of the mounting frame 401 is provided with a lifting and conveying assembly 5. The lifting and conveying assembly 5 includes a support plate 501. Multiple support plates 501 are symmetrically arranged, and a belt structure 502 is installed between the support plates 501. A hydraulic rod 503 is installed on one side of the support plate 501. Figure 1 , 4 As shown, when the sheet material to be coated is placed on the limiting plates 504 on both sides, that is, the rotating wheels 505, the hydraulic rod 503 is activated. At this time, the sheet material can be passed between the first brush bristles 413 and the second brush bristles 416, so that the hydraulic rod 503 drives the limiting plate 504 to rise. Then the limiting plate 504 will drive the sheet material to rise, and then the top of the sheet material will abut against the belt structure 502. At this time, the belt structure 502 is activated, so that the belt structure 502 conveys the sheet material. During the conveying process, the surface of the sheet material is cleaned by the cleaning and adjustment component 4. Finally, the sheet material is coated by the rubber roller 201 and the idler roller 203, so that the sheet material of different specifications can be adjusted and fixed for conveying. The top of the hydraulic rod 503 is fixedly connected to the limiting plate 504, and multiple rotating wheels 505 rotate symmetrically inside the limiting plate 504.

[0034] Working principle: Before using the lifting and adjusting mechanism of this type of roller coating machine, it is necessary to check the overall condition of the device to ensure that it can operate normally. Figure 1 - Figure 6 As shown, firstly, the position of the roller 203 is adjusted by the electric actuator 205, thus enabling roller coating of sheets of different thicknesses. Then, during the roller coating process, the second motor 403 is started, which drives the circular block 404 to rotate. The circular block 404 then drives the toothed block 405 to move in a circular motion. The toothed block 405 then drives the rack 410 to move, while the first spring 407 is stretched. When the toothed block 405 reaches a certain distance, it disengages from the rack 410, and the first spring 407 rebounds, causing the rack 410 to reset. When the toothed block 405 reaches a certain distance, it resets. Engaging with rack 410, rack 410 repeatedly performs the above actions, and then rack 410 moves back and forth, which in turn drives slide plate 411 to move back and forth. Slide plate 411 cleans both sides of the board simultaneously, allowing the board to be surface-cleaned before roller coating, thereby improving the quality of roller coating. Next, rotating threaded rod 414 causes threaded rod 414 to rotate and descend, which in turn causes the position of second bristles 416 to descend, thereby allowing the position of second bristles 416 to be adjusted up and down to adapt to the surface cleaning of boards of different widths.

[0035] When the sheet material to be coated is placed on the limiting plates 504 on both sides, i.e., the rotating wheel 505, the hydraulic rod 503 is activated. The sheet material can then pass between the first brush 413 and the second brush 416, causing the hydraulic rod 503 to lift the position of the limiting plate 504. The limiting plate 504 will then lift the sheet material, and the top of the sheet material will press against the belt structure 502. The belt structure 502 is then activated to transport the sheet material. During the transport process, the surface of the sheet material is cleaned by the cleaning and adjustment component 4. Finally, the sheet material is coated with adhesive by the rubber roller 201 and the idler roller 203, thus allowing for the adjustment and fixed transport of sheet materials of different specifications.

[0036] 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.
