Description

Technical Field

[0001] This utility model relates to the technical field of fabric pressing devices, specifically a fabric pressing device for a coating machine. Background Technology

[0002] Coating machines are widely used in textile, leather, and functional material manufacturing industries. They add waterproof, stain-resistant, and other functional coatings to materials through coating processes, thereby improving material performance. The pressing device, as a core component, is responsible for pressing the material to be coated tightly onto the coating surface, ensuring uniform and firm adhesion of the coating. In both large-scale and small-batch production, this is crucial for ensuring coating quality and improving production efficiency.

[0003] In the prior art, such as the fabric pressing device of a coating machine in patent number CN213558145U, a base is included. A roller bracket is fixedly connected to the surface of the base. A fabric roller is provided on the side wall of the roller bracket. A plurality of first support columns are fixedly connected to the surface of the base and near the left side of the roller bracket. A first moving groove is opened inside the first support column. A gear is provided in the groove of the first moving groove. A moving plate is provided on the top of the gear. The plurality of moving plates are fixedly connected by a connecting rod. The plurality of moving plates are rotatably connected to a first roller by a bearing. A plurality of second support columns are fixedly connected to the surface of the base and near the left side of the first support columns. A second roller is provided on the top of the second support columns. A lifting platform is provided on the surface of the base and near the left side of the second support columns. A limit device is fixedly connected to the top of the lifting platform.

[0004] While the aforementioned patents can compress fabric, they still have some problems. When the fabric has wrinkles, directly using pressure rollers to squeeze and remove wrinkles not only makes it difficult to smooth them out, but may also cause these wrinkles to pile up under pressure, forming more complex and difficult-to-handle creases, further affecting the wrinkle removal effect and the smoothness of the fabric. Therefore, this utility model provides a fabric pressing device for a coating machine. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a fabric pressing device for a coating machine, which solves the problem that when the fabric has wrinkles, directly using pressure rollers to squeeze and remove wrinkles not only makes it difficult to smooth out these wrinkles, but may also cause them to pile up under pressure, forming more complex and difficult-to-handle creases, further affecting the wrinkle removal effect and the smoothness of the fabric.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a fabric pressing device for a coating machine, comprising a base plate, characterized in that: an anti-wrinkle component and a pressing component are respectively provided on the top of the base plate;

[0009] Preferably, a mounting frame is fixedly installed at the top of the base plate, and two electric push rods are respectively fixedly installed on both sides of the inner wall of the mounting frame. Two rotating rods are rotatably installed on the inner wall of the mounting frame, and two sliding strips are fixedly installed on the outer wall of the rotating rods.

[0010] Preferably, the two sliding bevel gears are slidably disposed on the outer walls of the rotating rod and the two slide bars. A connecting plate is rotatably mounted on the outer wall of the sliding bevel gears. The connecting plate is fixedly connected to the connecting frame. Two first motors are fixedly mounted on the top of the mounting frame.

[0014] Beneficial effects

[0015] This invention provides a fabric pressing device for a coating machine. Compared with the prior art, it has the following advantages:

[0016] 1. The fabric pressing device of this coating machine, before the fabric is pressed, first places the fabric between multiple sets of ball bearings, then simultaneously activates two electric push rods. The two electric push rods drive multiple mounting brackets to approach each other through the connecting frame until the ball bearings on the mounting brackets are in contact with the fabric surface. Then, simultaneously activates two first motors, which drive two rotating rods to rotate. The rotating rods drive the sliding bevel gear to rotate, thereby driving the first bevel gear and the transmission belt to rotate. The transmission belt drives the ball bearings on the surface to rotate, thereby stretching the fabric to both sides. This eliminates wrinkles on the fabric surface and prevents the fabric wrinkles from stacking together and forming complex creases during pressing, greatly improving the flatness of the fabric and enhancing the uniformity and quality of the subsequent coating.

[0017] 2. The fabric pressing device of this coating machine starts with the second motor, whose output shaft drives a bidirectional screw to rotate. As the bidirectional screw rotates, the two frames move towards or away from each other, thereby adjusting the distance between the two extrusion rollers. The fabric, initially treated by the anti-wrinkle component, is fed between the two extrusion rollers. The extrusion rollers, with precisely controlled pressure, perform a secondary wrinkle removal operation on the fabric. During the extrusion process, the extrusion rollers further smooth out any remaining fine wrinkles on the fabric, ensuring that the fabric adheres more closely to the coating surface in a smoother state, laying a solid foundation for the uniformity of subsequent coating operations.

[0025] 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.

[0026] This utility model provides two technical solutions:

[0027] Figures 1-6 The first embodiment is shown: a pressing device for a coating machine, including a base plate 1, characterized in that: an anti-wrinkle component 2 and a pressing component 3 are respectively provided on the top of the base plate 1;

[0028] The anti-wrinkle component 2 includes two electric push rods 22. A connecting frame 23 is fixedly installed at the output end of the electric push rod 22. Two mounting frames 24 are fixedly installed on the outer wall of the connecting frame 23. The electric push rod 22 is existing technology and can drive the two mounting frames 24 to rise and fall simultaneously through the connecting frame 23. Two transmission rollers 25 are rotatably installed on the inner wall of the mounting frame 24. A transmission belt 26 is sleeved on the outer wall of the two transmission rollers 25. A set of fixed plates 27 are evenly installed on the outer wall of the transmission belt 26. A set of balls 28 are rolled on the outer wall of the fixed plates 27. The balls 28 can roll and rotate, so when the balls 28 come into contact with the fabric surface, they will not affect the normal feeding of the fabric. The outer wall of one of the two transmission rollers 25 passes through the mounting frame 24. When the first bevel gear 29 rotates, it can drive one transmission roller 25 to rotate, which in turn can drive the transmission belt 26 and the fixed plate 27 and balls 28 on the surface to rotate. The first bevel gear 29 is fixedly installed, and a sliding bevel gear 213 is meshed on the outer wall of the first bevel gear 29.

[0029] The extrusion assembly 3 includes two frames 34, and extrusion rollers 35 are rotatably mounted on the inner walls of both frames 34.

[0030] A mounting frame 21 is fixedly installed at the top of the base plate 1. Two electric push rods 22 are fixedly installed on both sides of the inner wall of the mounting frame 21. Two rotating rods 210 are rotatably installed on the inner wall of the mounting frame 21. Two sliding strips 211 are fixedly installed on the outer wall of the rotating rods 210.

[0031] Two sliding bevel gears 213 are slidably mounted on the outer walls of the rotating rod 210 and the two slide bars 211. The sliding bevel gears 213 can slide on the surfaces of the rotating rod 210 and the two slide bars 211. Due to the arrangement of the slide bars 211, when the slide bars 211 rotate, they can drive the sliding bevel gears 213 to rotate. When the connecting plate 212 moves, it can drive the sliding bevel gears 213 to move. The connecting plate 212 is rotatably mounted on the outer wall of the sliding bevel gears 213. The connecting plate 212 is fixedly connected to the connecting frame 23. Figure 4 It can be observed that the meshing method of the two sliding bevel gears 213 is different from that of the two first bevel gears 29. Therefore, when the rotating rod 210 rotates, the rotation directions of the two first bevel gears 29 are opposite, which enables the transmission belts 26 on the two mounting brackets 24 to rotate in opposite directions. This allows the balls 28 on one side of the two transmission belts 26 to stretch one side of the fabric outward to prevent wrinkles. Two first motors 214 are fixedly installed at the top of the mounting frame 21. The output shafts of the two first motors 214 pass through the inner wall of the mounting frame 21 and are fixedly connected to one end of the outer wall of the two rotating rods 210 respectively.

[0032] Figures 1-6 The second embodiment is shown. The main difference from the first embodiment is that: a housing 31 is fixedly installed on the top of the base plate 1, and a bidirectional screw 32 is rotatably installed on the inner wall of the housing 31. The outer wall of the bidirectional screw 32 is threadedly connected to two frames 34 respectively. When the bidirectional screw 32 rotates, it can drive the two frames 34 to move closer or further away from each other, thereby adjusting the distance between the two extrusion rollers 35.

[0033] Both frames 34 are movably inserted into the inner wall of the housing 31. A second motor 33 is fixedly installed at the top of the housing 31. The output end of the second motor 33 passes through the inner wall of the housing 31 and is fixedly connected to one end of the outer wall of the bidirectional screw 32.

[0034] Two vertical plates 4 are fixedly installed at the top of the base plate 1. A fabric roller 5 is rotatably installed between the opposite sides of the two vertical plates 4. A third motor 6 is fixedly installed on the outer wall of one of the two vertical plates 4. The output shaft of the third motor 6 passes through the outer wall of the vertical plate 4 and is fixedly connected to one end of the outer wall of the fabric roller 5.

[0035] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0036] During operation, before the fabric is compressed, it is first positioned between multiple sets of ball bearings 28. Then, two electric push rods 22 are simultaneously activated. The two electric push rods 22 drive multiple mounting brackets 24 to move closer together through the connecting frame 23 until the ball bearings 28 on the mounting brackets 24 are in contact with the fabric surface. Then, two first motors 214 are simultaneously activated. The two first motors 214 drive two rotating rods 210 to rotate. One rotating rod drives two sliding bevel gears 213 to rotate, thereby driving the two first bevel gears 29 and the transmission belt 26 to rotate in the opposite direction. The direction of rotation causes the transmission belt 26 to drive the surface balls 28 to rotate, thereby stretching the fabric to both sides. This eliminates wrinkles on the fabric surface and prevents wrinkles from stacking together and forming complex creases during compression, greatly improving the flatness of the fabric and enhancing the uniformity and quality of subsequent coatings. The fabric is then passed between the two compression rollers 35, and the second motor 33 is started. Its output shaft drives the bidirectional screw 32 to rotate. When the bidirectional screw 32 rotates, the two frames 34 move towards or away from each other, thereby adjusting the distance between the two compression rollers 35. The fabric, initially treated by the anti-wrinkle component 2, is then conveyed between the two compression rollers 35, where the compression rollers 35 perform a secondary wrinkle removal operation on the fabric using precisely controlled pressure. During extrusion, the extrusion roller 35 further smooths out any minor wrinkles that may remain on the fabric, ensuring that the fabric adheres more closely to the coating surface in a flatter state, laying a solid foundation for the uniformity of subsequent coating operations. After the fabric is placed, the third motor 6 is started, and its output shaft drives the fabric roller 5 to rotate, gradually releasing the fabric wrapped on the fabric roller 5. The fabric passes through the anti-wrinkle component 2 and the extrusion component 3 in sequence, and enters the coating stage after completing the wrinkle removal and extrusion bonding process.
