Description

Technical Field

[0001] This utility model relates to the field of anti-wrinkle coating technology, and in particular to an anti-wrinkle coating mechanism. Background Technology

[0002] Coating technology is a papermaking process that uses an adhesive to brush a cementitious material onto the paper surface to improve its properties. Based on the processing method, coating technology can be divided into two main categories: dry coating and wet coating. The coating materials used include various adhesives, water-soluble paints, inks, etc., which quickly form a stable film on the substrate surface after coating.

[0003] During the coating production process, the tension of the equipment and the stress inherent in the substrate itself can cause wrinkles to appear on the substrate during winding. Usually, people use some auxiliary equipment to avoid this situation. For example, Chinese utility model patent with patent publication number CN221190959U discloses a coating winding auxiliary device. This auxiliary device sets a pressure roller on the winding roller, so that the substrate passes between the pressure roller and the winding roller. The pressure roller smooths out the wrinkles on the substrate. By using elastic elements with different tensions, the pressure of the pressure roller on the winding roller can be changed, thereby adjusting the roller pressure state according to the wrinkle situation and improving the smoothing effect of the wrinkles.

[0004] However, in actual operation, the aforementioned auxiliary device cannot control the downward pressure of the elastic belt on the take-up roller. When the substrate thickness is too large, the pressure of the pressure roller also increases, which can easily cause difficulties in feeding the substrate. When the substrate thickness is too small, the pressure of the pressure roller will also decrease, which can easily cause unevenness and wrinkles. In summary, the application scenarios of this auxiliary device are relatively limited, resulting in poor applicability. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this utility model provides a coating anti-wrinkle mechanism, which solves the problem that the application scenarios of existing technologies are relatively limited, resulting in poor applicability.

[0006] According to an embodiment of the present invention, a coating anti-wrinkle mechanism includes a frame, support members, pressing members, elastic members, and distance control members. The support members are arranged in pairs and vertically on the top of the frame. The pressing members include a pair of pressing strips arranged between the support members and used to flatten wrinkles in the substrate. The elastic members are located at the connection between the support members and the pressing members. The distance control members are located on opposite sides of the support members and used to adjust the distance between the two pressing members.

[0007] In the above embodiments, the opposing pressure members are connected to the support members through elastic members. The substrate can pass through the two opposing pressure strips in the pressure members. The spacing between the pressure strips can be controlled by the distance control member and can be adjusted according to different substrate thicknesses to always maintain a full and appropriate downward pressure on the substrate.

[0008] In some embodiments, the support member includes two sets of limiting rods fixedly disposed on both sides of the center of the top of the frame and two crossbars slidably disposed on the adjacent sides of the two sets of limiting rods. One side of the two crossbars on the same set of limiting rods is provided with a connecting rod connected to the end side of the pressing member, and the other side of the two crossbars on the same set of limiting rods is connected to the two distance control members respectively.

[0011] In some embodiments, a heating block is provided between the rotating shafts in the same group, which contacts the inner side of the pressure belt.

[0012] In some embodiments, the elastic element includes a strip groove respectively formed at the connection between the connecting rod and the rotating shaft, and a slider slidably disposed in the strip groove. The slider is rotatably connected to the end side near the rotating shaft. A sliding rod is fixedly connected to the side of the slider away from the rotating shaft. A circular sliding hole adapted to the sliding rod is formed on the side wall of the strip groove away from the slider.

[0013] In some embodiments, the distance control component includes two screws that are rotatably disposed opposite to each other on the top of the frame and two pairs of threaded sleeves respectively sleeved on the outside of the two screws. The two threaded sleeves located on the same screw are respectively fixedly connected to the adjacent side of the crossbar located on the same side, and the top ends of the two screws are provided with transmission components.

[0014] In some embodiments, the transmission component includes sprockets fixedly connected to the top ends of the two screws and chain links sleeved on the outside of the two sprockets.

[0015] Compared with the prior art, this utility model has the following beneficial effects: by adopting a pressure strip with a relatively large contact area and elastic connection with the distance control component, it solves the technical problem that the application scenarios of the existing anti-wrinkle mechanism are relatively limited, resulting in poor applicability of operation, thereby achieving the technical effect of always maintaining a full and appropriate downward pressure on the substrate.

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0022] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0023] In an exemplary implementation, such as Figures 1-4As shown, this embodiment provides a coating anti-wrinkle mechanism, including a frame 100, support members 200, pressing members 300, elastic members 400, and distance control members 500. The support members 200 are arranged in pairs and vertically on the top of the frame 100. The pressing members 300 include a pair of pressing strips 310, which are arranged between the support members 200 and used to flatten the wrinkles of the substrate. The elastic members 400 are arranged at the connection between the support members 200 and the pressing members 300. The distance control members 500 are arranged on opposite sides of the support members 200 and used to adjust the distance between the two pressing members 300.

[0024] In this embodiment, the pressure members 300 arranged opposite to each other are connected to the support member 200 through the elastic member 400. The substrate can pass through the two pressure strips 310 arranged opposite to each other in the pressure member 300. The spacing of the pressure strips 310 can be controlled by the distance control member 500. It can be adjusted according to different substrate thicknesses to always maintain a full and appropriate downward pressure on the substrate.

[0025] In one embodiment, please refer to Figures 1-3 The support member 200 includes two sets of limiting rods 210 fixedly disposed on both sides of the top center of the frame 100 and two crossbars 220 slidably disposed on the sides of the two sets of limiting rods 210. One side of the two crossbars 220 on the same set of limiting rods 210 is provided with a connecting rod 230 connected to the end side of the pressing member 300. The other side of the two crossbars 220 on the same set of limiting rods 210 is connected to the two distance control members 500 respectively.

[0026] In this embodiment, the distance control member 500 can make the two crossbars 220 move closer or further apart, so that the crossbars 220 can drive the pressing members 300 on the connecting rod 230 to move closer or further apart, so that the pressing members 300 can adapt to materials of more different thicknesses.

[0027] In one embodiment, please refer to Figures 1-3 The pressure component 300 also includes two sets of rotating shafts 320 respectively disposed in the two pressure belts 310. The two pressure belts 310 are vertically opposite to each other. The two ends of the rotating shafts 320 are rotatably connected to the adjacent connecting rods 230 respectively. The elastic element 400 is disposed at the connection between the rotating shafts 320 and the connecting rods 230.

[0028] In this embodiment, the pressure belt 310 is rotatably mounted on the connecting rod 230 via the rotating shaft 320, and the connection between the rotating shaft 320 and the connecting rod 230 is achieved through the elastic element 400.

[0029] Furthermore, the pressure belt 310 and the rotating shaft 320 are not in direct contact, but are installed using common existing methods, such as connecting them through corresponding rollers.

[0030] In one embodiment, please refer to Figure 1 and Figure 2Both ends of the pair of crossbars 220 are rotatably provided with rotating rods 221. A coil spring 222 is provided at the connection between the rotating rod 221 and the crossbar 220. A rotating roller 223 is rotatably provided between the ends of the rotating rods 221 and the two rotating rollers 223 located on the same side abut against each other.

[0031] In this embodiment, the corresponding coil spring 222 causes the corresponding rotating rod 221 to always rotate clockwise or counterclockwise, so that the rotating rollers 223 on the same side can abut against each other. The rotating rollers 223 on both sides can stretch the substrate to keep it flat, which is more conducive to flattening the pressure strip 310.

[0032] In one embodiment, please refer to Figure 3 A heating block 321 is provided between the rotating shafts 320 in the same group, which is in contact with the inner side of the pressure belt 310.

[0033] In this embodiment, the heating block 321 appropriately heats the pressing strip 310, which is more conducive to smoothing out the wrinkles of the substrate.

[0034] In one embodiment, please refer to Figures 1-3 The elastic element 400 includes a strip groove 410 respectively opened at the connection between the connecting rod 230 and the rotating shaft 320 and a slider 420 slidably disposed in the strip groove 410. The slider 420 is rotatably connected to the end side of the rotating shaft 320. A slider rod 430 is fixedly connected to the side of the slider 420 away from the rotating shaft 320. A circular sliding hole 440 adapted to the slider rod 430 is opened on the side wall of the strip groove 410 away from the slider 420. A spring 450 is sleeved on the outside of the slider rod 430 and is connected to one side of the slider 420 and the inner wall of the strip groove 410 respectively.

[0035] In this embodiment, the rotating shaft 320 can compress the spring 450 outside the slide bar 430 through the slider 420. The spring 450 can push the pressure strip 310 on the rotating shaft 320 in the opposite direction, so that the pressure strip 310 always abuts against the substrate.

[0036] In one embodiment, please refer to Figure 1 The distance control component 500 includes two screws 510 that are rotatably disposed on the top of the frame 100 and two pairs of threaded sleeves 520 respectively sleeved on the outside of the two screws 510. The two threaded sleeves 520 located on the same screw 510 are respectively fixedly connected to the adjacent side of the crossbar 220 located on the same side. The top end of the two screws 510 is provided with a transmission component 600.

[0037] The transmission component 600 includes sprockets 610 fixedly connected to the top ends of the two screws 510 and chain links 620 sleeved on the outside of the two sprockets 610.

[0038] In this embodiment, rotating one of the screws 510 drives the sprocket 610 through the chain link 620, so that the other screw 510 can rotate together. At the same time, the rotation of the screws 510 causes the same set of screw sleeves 520 to move closer to each other. At this time, the rotating shaft 320 on the crossbar 220 and the pressure belt 310 on it move closer to each other, thereby realizing the adjustment of the distance.

[0039] Finally, a motor 700 can be installed at one end of the rotating shaft 320, which can drive the pressure belt 310 to ensure the material feeding effect.

[0040] To better understand this utility model, the following is combined with... Figures 1 to 4 The technical solution of this utility model is described in detail as follows: In use, the substrate passes through two rotating rollers 223 on one side of the frame 100 and enters between two pressure belts 310. Finally, it passes through two rotating rollers 223 on the other side of the frame 100 to enter the next stage. During this process, according to the thickness of the substrate, one of the screws 510 is rotated. The screw 510 drives the sprocket 610 through the chain link 620, so that the other screw 510 can rotate together. At the same time, the rotation of the screw 510 causes the same set of screw sleeves 520 to move closer or further away from each other. The movement of the screw sleeves 520 can drive the connecting rod 230 to move. The connecting rod 230 drives the pressure belt 310 to move closer or further away through the rotating shaft 320, thereby realizing the adjustment of the distance.

[0041] Furthermore, the rotating shaft 320 on the pressure belt 310 can compress the spring 450 outside the slide bar 430 through the slider 420. The spring 450 can push the pressure belt 310 on the rotating shaft 320 in the opposite direction, so that the pressure belt 310 always abuts against the substrate, and can also avoid excessive downward pressure affecting the movement of the substrate.

[0042] In summary, this utility model solves the technical problem of limited application scenarios and poor operational applicability of existing anti-wrinkle mechanisms by using a pressure strip 310 with a relatively large contact area and elastic connection with the distance control component 500, thereby achieving the technical effect of always maintaining sufficient and appropriate downward pressure on the substrate.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
