Description

Technical Field

[0001] This utility model relates to the field of coating machine technology, specifically to a coating structure for a coating machine that is easy to adjust. Background Technology

[0002] A coating machine is a mechanical device used to coat the surface of objects with liquids, adhesives, paints, and other materials. It achieves efficient and uniform material coating and is widely used in industrial production and manufacturing processes. The advantages of using a coating machine include increased production efficiency, guaranteed coating quality, and savings in materials and human resources. However, when using a coating machine, it is essential to pay attention to safe operation and follow the equipment's operating instructions for operation and maintenance to ensure smooth operation and long-term use of the equipment.

[0003] The prior art patent application number is 202323233278.7, entitled "A Coating Thickness Adjustment Structure for a Coating Machine." When adjusting the coating thickness during coating machine operation, rotating a rotating block drives a threaded rod to rotate. The threaded rod passes through a threaded groove on a first sliding plate, causing the first sliding plate to slide within a sliding cavity. The sliding cavity moves upward, and the first sliding plate moves the extrusion roller upward. The extrusion roller then drives the second sliding plate to slide within the sliding cavity, increasing the distance between the extrusion roller and the coating roller. When the rotating block is rotated in the opposite direction, the distance between the extrusion roller and the coating roller decreases, allowing the coating machine to adjust the coating thickness. After coating, the product moves to below the scraping assembly, where a scraper spreads the coating evenly. To prevent uneven coating, the coating roller lacks a stabilizing mechanism, causing vibration that leads to fluctuations in the gap between the coating roller and the substrate. This results in streaks, wavy lines, or localized thickness differences in the coating. Vibration can also cause slurry splashing, bubbles, or cracking, especially noticeable during high-speed coating. Furthermore, the threaded rod is not equipped with a locking mechanism, and it may rotate on its own due to vibration or external forces during operation. This can cause axial displacement of the extrusion roller mounted on the threaded rod, which gradually moves downwards. This structural defect not only affects the positioning accuracy of the extrusion roller but may also cause uncontrolled gap between the roller and the material. Therefore, we propose a coating structure for coating machines that is easy to adjust. Utility Model Content

[0004] The purpose of this utility model is to provide a coating structure for a coating machine that is easy to adjust, in order to solve the problems mentioned in the background art, where the lack of a stabilizing mechanism during the rotation of the coating roller causes vibration, resulting in fluctuations in the gap between the coating roller and the substrate, causing stripes, wavy patterns or local thickness differences in the coating, and the lack of a locking mechanism on the threaded rod, which may rotate on its own due to vibration or external force during operation, leading to axial displacement and gradual downward movement of the extrusion roller mounted on the threaded rod.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a coating structure for an easily adjustable coating machine, comprising a frame and two mounting chambers, the two mounting chambers being fixedly connected to the top of the frame, two support legs being provided below the frame, a liquid storage cylinder being fixedly connected inside the support legs, the liquid storage cylinder being filled with damping oil, a sealing ring being bonded to the top of the liquid storage cylinder, a return spring being fixedly connected around the top of the liquid storage cylinder and the return springs being evenly distributed, the top of the return spring being fixedly connected to the frame, a connecting rod being inserted into the top of the liquid storage cylinder, and a threaded rod being rotatably connected to the inner cavity of one side of the mounting chamber.

[0006] As a further description of the above technical solution:

[0007] The top end of the connecting rod is fixedly connected to the frame, the bottom end of the connecting rod passes through the liquid storage cylinder and extends into the inner cavity of the liquid storage cylinder, and a seepage plate is fixedly connected to the bottom end of the connecting rod.

[0008] As a further description of the above technical solution:

[0009] The top of the seepage plate has seepage holes around its circumference, and the seepage holes are evenly distributed. Two friction sleeves are fixedly connected to the outer side of the support leg, and four friction rods are fixedly connected to the outer side of the frame.

[0010] As a further description of the above technical solution:

[0011] The outer side of the friction rod contacts the friction sleeve, and the top of the frame is provided with a mounting groove, on the inner side of which a coating roller is rotatably connected.

[0012] As a further description of the above technical solution:

[0013] The top end of the threaded rod passes through the mounting chamber and extends to the top of the mounting chamber. A limit rod is fixedly connected to the inner cavity of the mounting chamber on the other side. A first mounting plate is screwed onto the outer side of the threaded rod.

[0014] As a further description of the above technical solution:

[0015] A second mounting plate is slidably connected to the outer side of the limiting rod, and a squeezing roller is rotatably connected between the inner sides of the first mounting plate and the second mounting plate. A mounting frame is fixedly connected to the top of one side of the mounting chamber.

[0016] As a further description of the above technical solution:

[0017] The mounting bracket is rotatably connected to a bidirectional screw, and two V-shaped limiting plates are screwed to the outer side of the bidirectional screw. The inner side of the V-shaped limiting plates abuts against the threaded rod.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. This easily adjustable coating machine structure, during the coating process, causes vibration in the coating roller and extrusion roller during rotation, which in turn vibrates the frame. A connecting rod connected to the frame receives this vibration. The connecting rod then moves, causing the drainage plate at its bottom to press against the damping oil in the storage tank. This forces the damping oil through drainage holes on the drainage plate to the other side, generating damping. Simultaneously, the movement of the connecting rod shortens the distance between the frame and the support legs, causing friction between the friction rod mounted on the frame and the friction sleeve mounted on the support legs, generating damping. The compressed return spring then resets, restoring the distance between the frame and the support legs. During this restoration process, the friction sleeve and friction rod generate damping again, as do the drainage plate and damping oil, effectively buffering the vibration generated by the coating roller and extrusion roller during rotation and improving the coating effect.

[0020] 2. This easily adjustable coating structure for a coating machine, after adjusting the height of the extrusion roller by rotating the threaded rod, causes the two V-shaped limiting plates mounted on the double-sided screw to come together by rotating the double-sided screw. This brings the two V-shaped limiting plates into contact with the outer side of the threaded rod, applying pressure to the threaded rod and increasing the friction between the threaded rod and the V-shaped limiting plates. This prevents the threaded rod from rotating automatically, thus preventing it from rotating on its own due to vibration or external forces. Attached Figure Description

Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0029] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] This utility model provides an easily adjustable coating structure for a coating machine, which can prevent the threaded rod 210 from rotating on its own due to vibration or external force. It effectively reduces the vibration generated during the rotation of the coating roller 161 and the extrusion roller 250, thus improving the coating effect. Please refer to [link / reference]. Figure 1-5 It includes a rack 100 and two mounting bays 200;

[0031] Please refer to it again. Figure 1-5 Two support legs 110 are provided below the frame 100. A liquid reservoir 120 is fixedly connected inside the support legs 110. The liquid reservoir 120 is filled with damping oil 121. A sealing ring 122 is bonded to the top of the liquid reservoir 120. Return springs 123 are evenly distributed and fixedly connected around the top of the liquid reservoir 120. The top of the return springs 123 is fixedly connected to the frame 100. A connecting rod 130 is inserted into the top of the liquid reservoir 120, and the top of the connecting rod 130 is fixedly connected to the frame 100. The bottom end of the connecting rod 130 penetrates the liquid storage cylinder 120 and extends into the inner cavity of the liquid storage cylinder 120. A seepage plate 131 is fixedly connected to the bottom end of the connecting rod 130. Seepage holes 132 are evenly distributed around the top of the seepage plate 131. Two friction sleeves 140 are fixedly connected to the outer side of the support leg 110. Four friction rods 150 are fixedly connected to the outer side of the frame 100. The outer sides of the friction rods 150 contact the friction sleeves 140. A mounting groove 160 is provided on the top of the frame 100. A coating roller 161 is rotatably connected to the side. During the coating process, the coating roller 161 and the extrusion roller 250 vibrate during rotation, causing the frame 100 to vibrate. The vibration is received by the connecting rod 130 connected to the frame 100. Subsequently, the connecting rod 130 moves, causing the seepage plate 131 at the bottom of the connecting rod 130 to squeeze the damping oil 121 in the storage cylinder 120. This causes the damping oil 121 to flow through the seepage holes 132 on the seepage plate 131 to the other side of the seepage plate 131, generating damping. At the same time, due to the connecting rod 161... The movement of 30 shortens the distance between the frame 100 and the support leg 110, causing the friction rod 150 mounted on the frame 100 and the friction sleeve 140 mounted on the support leg 110 to rub against each other during the shortening process, generating damping. Then, the compressed return spring 123 returns to its original position, restoring the distance between the frame 100 and the support leg 110. During the restoration process, the friction sleeve 140 and the friction rod 150 generate damping again, and at the same time, the seepage plate 131 and the damping oil 121 also generate damping again, thus buffering the vibration.

[0032] In summary, this method can effectively reduce the vibration generated by the coating roller 161 and the extrusion roller 250 during the coating process, thereby improving the coating effect.

[0033] Please refer to it again. Figure 1-5Two mounting chambers 200 are fixedly connected to the top of the frame 100. A threaded rod 210 is rotatably connected to the inner cavity of one mounting chamber 200, with the top end of the threaded rod 210 penetrating the mounting chamber 200 and extending to the top of the mounting chamber 200. A limit rod 220 is fixedly connected to the inner cavity of the other mounting chamber 200. A first mounting plate 230 is screwed to the outer side of the threaded rod 210, and a second mounting plate 240 is slidably connected to the outer side of the limit rod 220. An extrusion roller 250 is rotatably connected between the inner sides of the first mounting plate 230 and the second mounting plate 240. A mounting frame 260 is fixedly connected to the top of one mounting chamber 200. A bidirectional screw 270 is rotatably connected to the inner side of the screw 60. Two V-shaped limiting plates 280 are screwed to the outer side of the bidirectional screw 270. The inner side of the V-shaped limiting plates 280 abuts against the threaded rod 210. After the height of the extrusion roller 250 is adjusted by rotating the threaded rod 210, the two V-shaped limiting plates 280 installed on the bidirectional screw 270 are brought together by rotating the bidirectional screw 270. The two V-shaped limiting plates 280 contact the outer side of the threaded rod 210, apply pressure to the threaded rod 210, and increase the friction between the threaded rod 210 and the V-shaped limiting plates 280, so that the threaded rod 210 cannot rotate automatically.

[0034] In summary, this prevents the threaded rod 210 from rotating on its own due to vibration or external force.

[0035] In practical use, when the coating roller 161 and the extrusion roller 250 vibrate during the coating process, the frame 100 vibrates. The connecting rod 130 connected to the frame 100 receives the vibration. Subsequently, the connecting rod 130 moves, causing the liquid-permeable plate 131 at the bottom of the connecting rod 130 to squeeze the damping oil 121 in the liquid storage cylinder 120. This causes the damping oil 121 to flow through the liquid-permeable holes 132 on the liquid-permeable plate 131 to the other side of the liquid-permeable plate 131, generating damping. At the same time, the movement of the connecting rod 130 shortens the distance between the frame 100 and the support leg 110, causing the friction rod 150 mounted on the frame 100 and the friction sleeve 140 mounted on the support leg 110 to engage in friction during the shortening of the distance. Friction generates damping, and the compressed return spring 123 then resets, restoring the distance between the frame 100 and the support leg 110. During this restoration process, the upper friction sleeve 140 and friction rod 150 generate damping again, and the seepage plate 131 and damping oil 121 also generate damping again, buffering the vibration. After rotating the threaded rod 210 to adjust the height of the extrusion roller 250, the two V-shaped limiting plates 280 mounted on the bidirectional screw 270 are brought together by rotating the bidirectional screw 270, so that the two V-shaped limiting plates 280 contact the outer side of the threaded rod 210, applying pressure to the threaded rod 210 and increasing the friction between the threaded rod 210 and the V-shaped limiting plates 280, preventing the threaded rod 210 from rotating automatically.

[0036] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0037] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
