Description

Technical Field

[0001] This utility model relates to the field of unwinding devices, and in particular to a dust removal unwinding device for a coating machine that improves the uniformity of edge cleaning. Background Technology

[0002] The unwinding unit of a coating machine is a key component of the coating production line. Its core function is to stably release the substrate (such as film, foil, nonwoven fabric, etc.) while ensuring neat edges and controllable tension, providing a uniform substrate input for subsequent coating processes. In existing coating machines, dust easily accumulates at the edges of the material during operation. To ensure coating effectiveness, a dust removal structure is installed on the unwinding unit to remove dust from the material edges.

[0003] In existing dust-collecting unwinding devices, dust is collected by suction. While this method can remove most of the dust, it is not ideal for material edges where static electricity can easily accumulate. Due to the attraction of static electricity, some dust adheres quite firmly, and relying solely on suction can result in dust residue. Furthermore, suction alone can cause uneven dust removal at the edges, which still affects subsequent coating operations. Utility Model Content

[0004] The main objective of this invention is to provide a dust removal and unwinding device for a coating machine that improves the uniformity of edge cleaning, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A dust removal and unwinding device for a coating machine that improves edge cleaning uniformity includes a base, a first support plate at one end of the base and a second support plate at the other end of the base, an unwinding roller and a first reduction motor on the first support plate, a first traction roller and a second traction roller between the first support plate and the second support plate, and a dust removal structure between the first support plate and the second support plate.

[0007] Preferably, the first traction roller and the second traction roller are provided with sprockets at one end of the second support plate, and the sprockets are provided with chains. The second support plate is provided with a second reduction motor, and the second reduction motor is connected to the first traction roller.

[0008] Preferably, the shaft of the unwinding roller is connected to the first reduction motor, and the second traction roller is connected to the dust removal structure.

[0009] Preferably, the dust removal structure includes a horizontal plate, an ion fan, a mounting plate, a cleaning assembly, a drive gear, a follower gear, a dust collection hood, and a dust collection pipe. The horizontal plate and the mounting plate are fixedly connected, and the horizontal plate is installed between a first support plate and a second support plate. Two ion fans are fixed on the horizontal plate and are symmetrically arranged on the horizontal plate. The cleaning assembly is rotatably installed between the first support plate and the second support plate. The drive gear is fixed on a second traction roller. The follower gear is fixed at the end of the cleaning assembly and meshes with the drive gear. The dust collection hood and the dust collection pipe are fixedly connected, and the dust collection pipe is installed on the mounting plate.

[0010] Preferably, the cleaning assembly includes a follower shaft, a connecting sleeve, a brush, a locking groove, and a locking post. The follower shaft is rotatably disposed between the first support plate and the second support plate. The connecting sleeve is fixedly connected to the brush and is sleeved on the follower shaft.

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] like Figures 1-3 As shown, a dust removal and unwinding device for a coating machine to improve edge cleaning uniformity includes a base 1, a first support plate 2 at one end of the base 1, and a second support plate 3 at the other end of the base 1. An unwinding roller 4 and a first reduction motor 5 are mounted on the first support plate 2. A first traction roller 7 and a second traction roller 8 are positioned between the first support plate 2 and the second support plate 3. A dust removal structure 6 is also positioned between the first support plate 2 and the second support plate 3. A sprocket is located at one end of the first traction roller 7 and the second traction roller 8, and a chain is mounted on the sprocket. A second reduction motor 9 is mounted on the second support plate 3 and is connected to the first traction roller 7. The shaft of the unwinding roller 4 is connected to the first reduction motor 5, and the second traction roller 8 is connected to the dust removal structure 6.

[0018] When using the coating machine, the material roll is unwound and moved by the unwinding device. Initially, the material roll is placed on the unwinding roller 4 on the first support plate 2. The dust removal structure 6 is connected to an external vacuum cleaner. After starting the first reduction motor 5 and the second reduction motor 9, the unwinding roller 4 rotates to perform the unwinding operation. At the same time, the first traction roller 7 rotates. During this process, due to the action of the sprocket and chain, the second traction roller 8 rotates synchronously, cooperating with the first traction roller 7 to pull the material. When the material moves through the area under the dust removal structure 6, the dust removal structure 6 performs dust removal and cleaning treatment on the edges of the material to ensure the cleanliness of subsequent coating.

[0019] According to the above implementation scheme, the dust removal structure 6 includes a horizontal plate 601, an ion fan 602, a mounting plate 603, a cleaning assembly 604, a drive gear 605, a follower gear 606, a dust collection hood 607, and a dust collection pipe 608. The horizontal plate 601 and the mounting plate 603 are fixedly connected, and the horizontal plate 601 is installed between the first support plate 2 and the second support plate 3. Two ion fans 602 are fixed on the horizontal plate 601 and are symmetrically arranged on the horizontal plate 601. The cleaning assembly 604 is rotatably installed between the first support plate 2 and the second support plate 3. The drive gear 605 is fixed on the second traction roller 8. The follower gear 606 is fixed at the end of the cleaning assembly 604 and is meshed with the drive gear 605. The dust collection hood 607 and the dust collection pipe 608 are fixedly connected, and the dust collection pipe 608 is installed on the mounting plate 603.

[0020] As the material passes under the dust removal structure 6, the ion fan 602 on the horizontal plate 601 operates to remove static electricity from the edges of the material, eliminating the electrostatic adsorption of dust. The second traction roller 8 rotates, causing the drive gear 605 to rotate. The drive gear 605 then drives the follower gear 606 to rotate in the opposite direction at a faster speed, thereby causing the cleaning component 604 to rotate in the opposite direction and clean the edges of the material. Since the static electricity removal process has already been completed, the dust is easily swept off the material. At the same time, the operation of the vacuum cleaner creates a negative pressure inside the suction pipe 608 and the suction hood 607. Under the action of negative pressure, the swept dust is sucked away, thus achieving a highly efficient dust removal effect.

[0021] The cleaning assembly 604 includes a follower shaft 6041, a connecting sleeve 6042, a brush 6043, a snap-fit ​​groove 6044, and a snap-fit ​​post 6045. The follower shaft 6041 is rotatably disposed between the first support plate 2 and the second support plate 3. The connecting sleeve 6042 is fixedly connected to the brush 6043 and is sleeved on the follower shaft 6041. The snap-fit ​​groove 6044 and the snap-fit ​​post 6045 are disposed on the connecting sleeve 6042.

[0022] When the cleaning assembly 604 is running, the follower gear 606 drives the follower shaft 6041 to rotate, and the connecting sleeve 6042 drives the brush 6043 to rotate together, thereby cleaning the edges of the material. When needed, the connecting sleeve 6042 can be quickly disassembled for replacement. During disassembly, the connecting sleeve 6042 is separated and removed. After replacing the connecting sleeve 6042 with a new one for the brush 6043, the two connecting sleeves 6042 are snapped into the appropriate positions on the follower shaft 6041. The snap-fit ​​post 6045 on one connecting sleeve 6042 is connected to the snap-fit ​​groove 6044 on the other connecting sleeve 6042, thus completing the installation of the connecting sleeve 6042. After installation, the cleaning can be continued.

[0023] It should be noted that the dust removal structure 6, which includes an ion fan 602, a cleaning component 604, a dust hood 607, and a dust suction pipe 608, works in conjunction with an external vacuum cleaner to effectively remove dust from the edges of materials, avoiding incomplete dust removal due to static electricity. It also increases the uniformity of dust removal at the edges. The cleaning component 604 has a follower gear 606 at the end of its follower shaft 6041, and a drive gear 605 at the end of the second traction roller 8. During the operation of the traction roller, it can reverse the rotation of the cleaning component 604 to increase its speed, eliminating the need for an additional drive source to clean the material. The increased speed also enhances the dust removal effect. The connecting sleeve 6042 in the cleaning component 604 is installed via a snap-fit ​​groove 6044 and a snap-fit ​​post 6045, allowing for quick assembly and disassembly. After installation on the follower shaft 6041, cleaning is performed using a brush 6043 without affecting the stability of the connecting sleeve 6042.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
