Description

Technical Field

[0001] This utility model is a dust-adhesive device for a copper foil slitting machine, belonging to the field of copper foil slitting machines. Background Technology

[0002] A copper foil slitting machine is a specialized piece of machinery used to cut wide copper foil into specific widths according to customer requirements. During the slitting process, the friction and stress generated when the copper foil is cut inevitably produce fine copper powder. This copper powder often adheres to the surface of the copper foil, causing it to become rough and thus affecting the flatness and smoothness of the copper foil.

[0003] Based on observations, these copper powders are mainly concentrated in the area 10 to 20 centimeters away from the cut surface, and the particle size is usually between 10 and 50 micrometers. Most copper foil slitting machines on the market currently lack dust removal capabilities. Even those equipped with non-contact dust removal systems are ineffective at removing heavier and larger particles, failing to completely resolve the issue of copper powder adhesion. Other systems employ contact dust removal, which includes adhesive rollers and paper rollers. A cylinder brings the adhesive roller into contact with the copper foil, and the paper roller into contact with the adhesive roller. The adhesive roller then transfers the copper powder from the foil to the paper roller. The paper roller has a cylindrical adhesive structure. As adhesion continues, the amount of copper powder on its surface increases. When a particular area has a high concentration of copper powder, its adhesion effect decreases. During copper foil slitting, it's difficult for workers to detect this decrease in adhesion in time, leading to a high probability that the copper powder adhering to the adhesive roller will re-adhere to the copper foil. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a dust-adhesion device for a copper foil slitting machine to solve the problems mentioned in the background art. This utility model prevents copper powder from re-adhering to the copper foil and improves the dust-adhesion effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dust-adhesive device for a copper foil slitting machine, comprising a bracket, the bracket being an L-shaped structure, a cylinder mounted at the center of one side of the bracket, a detachable side plate mounted at one end of the bracket, a dust-adhesive roller rotatably mounted between the side plate and the bracket, a support shaft provided on the side of the dust-adhesive roller near the cylinder, an elongated oval opening on one side of the side plate and the side of the bracket facing the side plate, two elongated oval openings respectively passing through the two ends of the support shaft, dust-adhesive tape wound on the support shaft, driving components connected to the bracket on both sides of the cylinder for driving the support shaft to move in the direction of the dust-adhesive roller, a take-up shaft driven by a servo motor provided on the upper side of the support shaft, support plates rotatably mounted on both ends of the take-up shaft, the two support plates respectively connected to the side plate and the bracket, and the end of the dust-adhesive tape away from the support shaft wound on the take-up shaft.

[0006] Furthermore, the driving component includes a straight cylinder. Two through holes symmetrically arranged about the cylinder are formed on one side of the bracket. Guide rods are inserted into each of the two through holes, and bushings are installed at one end of each guide rod. The bushings are respectively fitted onto both ends of the support shaft. A straight cylinder, concentrically arranged with the through hole, is located at the end of the through hole away from the bushings. One end of the straight cylinder is connected and fixed to the bracket. A disc is installed at the end of the guide rod inside the straight cylinder. A spring is provided on the side of the disc away from the guide rod, and the spring is arranged along the length of the straight cylinder. A detachable cap is installed at the end of the straight cylinder away from the bracket. The two ends of the spring contact the disc and the cap, respectively.

[0007] Furthermore, a connecting ring is fitted onto the end of the straight cylinder away from the support, and the connecting ring is connected to the cylinder cover by multiple sets of bolts.

[0008] Furthermore, an ear plate is fixedly connected to the end of the side plate away from the adhesive roller. The ear plate is arranged perpendicular to the side plate and is connected to the bracket by multiple sets of bolts.

[0009] Furthermore, the side plate is provided with a first shaft hole at the end away from the bracket and at the end of the bracket, and the two ends of the adhesive roller are respectively rotatably installed in the two first shaft holes.

[0010] Furthermore, each of the two support plates has a second shaft hole at its upper end, and both ends of the winding shaft are rotatably installed in the second shaft hole.

[0011] Furthermore, a flange for connecting the output shaft of a servo motor is installed at one end of the take-up shaft, and the flange is located at the end of the take-up shaft away from the side plate.

[0012] The beneficial effects of this utility model are:

[0013] 1. The cylinder body is mounted on a support carrier, and a guide rail is used to support the bracket and limit its movement. When the cylinder extends, the adhesive roller contacts the copper foil that passes over the steel roller and the cutter roller. As the copper foil moves along the steel roller and the cutter roller, it forces the adhesive roller to rotate. Under the action of the spring rebound force, the adhesive tape on the support shaft contacts the adhesive roller, thus transferring the copper powder adhering to the adhesive roller to the adhesive tape. The servo motor drives the winding shaft to rotate, and the adhesive tape with copper powder adhering to it is wound onto the winding shaft. The adhesive tape without copper powder adhering to it unfolds from the support shaft and contacts the adhesive roller, thus preventing the adhesive tape with copper powder adhering to it from contacting the adhesive roller again and preventing copper powder from adhering to the copper foil again, thereby improving the dust adhesion effect.

[0014] 2. Place the two bushings on both ends of the support shaft. The interaction between the rolled adhesive tape and the adhesive roller causes the spring to be in a compressed state in the initial state. As the diameter of the adhesive tape on the support shaft gradually shortens due to use, the spring rebound force, through the transmission of the disc, guide rod and bushing, causes the support shaft to move along the elongated opening, so that the adhesive tape on the support shaft is always in contact with the adhesive roller until the adhesive tape on the support shaft is used up.

[0015] 3. After separating the side plate and the bracket, it is easy to remove the support shaft that has used up the adhesive tape and replace it with a new support shaft with adhesive tape. It is also easy to transfer the adhesive tape wound on the take-up shaft. Attached Figure Description

Detailed Implementation

[0022] 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.

[0023] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a dust-adhesive device for a copper foil slitting machine, including a bracket 1, which is an L-shaped structure. A cylinder 11 is installed in the middle of one side of the bracket 1. A detachable side plate 3 is installed at one end of the bracket 1. An ear plate 2 is connected and fixed to the end of the side plate 3 away from the dust-adhesive roller 6. The ear plate 2 and the side plate 3 are arranged perpendicular to each other, so that the ear plate 2 is connected to the bracket 1 by multiple sets of bolts to complete the assembly of the side plate 3 and the bracket 1. After separating the side plate 3 and the bracket 1, it is convenient to take out the support shaft 4 that has consumed the dust-adhesive tape 7 and replace it with a new support shaft 4 with dust-adhesive tape 7. At the same time, it is convenient to transfer the dust-adhesive tape 7 wound on the winding shaft 10.

[0024] See Figure 1 and Figure 2 A dust-adhesive roller 6 is rotatably installed between the side plate 3 and the bracket 1. The side plate 3 and the bracket 1 are both provided with a first shaft hole 17, so that the two ends of the dust-adhesive roller 6 are respectively rotatably installed in the two first shaft holes 17, thus completing the rotatable connection between the dust-adhesive roller 6 and the side plate 3 and the bracket 1.

[0025] See Figures 1-4A support shaft 4 is provided on the side of the adhesive roller 6 near the cylinder 11. An elongated oval opening 5 is provided on one side of the side plate 3 and the side of the bracket 1 facing the side plate 3. Two elongated oval openings 5 ​​pass through both ends of the support shaft 4. Adhesive tape 7 is wound around the support shaft 4. A take-up shaft 10 driven by a servo motor is provided on the upper side of the support shaft 4. A flange 9 for connecting the output shaft of the servo motor is installed at one end of the take-up shaft 10. The flange 9 is located at the end of the take-up shaft 10 away from the side plate 3. Support plates 8 are rotatably mounted on both ends of the take-up shaft 10. A second shaft hole 16 is provided on the upper end of each support plate 8, allowing both ends of the take-up shaft 10 to be rotatably mounted in the second shaft hole 16, completing the rotatable connection between the take-up shaft 10 and the support plates 8. The two support plates 8 are connected to the side plate 3 and the bracket 1, respectively. The end of the adhesive tape 7 away from the support shaft 4 is wound around the take-up shaft 10, making... The cylinder body of cylinder 11 is mounted on a support carrier, and a guide rail is used to support bracket 1 and limit the movement trajectory of bracket 1. When cylinder 11 extends, the adhesive roller 6 comes into contact with the copper foil that passes over the steel roller and the cutter roller. As the copper foil moves along the steel roller and the cutter roller, it forces the adhesive roller 6 to rotate. Under the action of the spring 21, the adhesive tape 7 on the support shaft 4 comes into contact with the adhesive roller 6, so that the copper powder attached to the adhesive roller 6 is transferred to the adhesive tape 7. The servo motor drives the winding shaft 10 to rotate. At this time, the adhesive tape 7 with copper powder is wound on the winding shaft 10, and the adhesive tape 7 without copper powder is unwound from the support shaft 4 and comes into contact with the adhesive roller 6, thereby preventing the adhesive tape 7 with copper powder from coming into contact with the adhesive roller 6 again, preventing the copper powder from adhering to the copper foil again, and improving the dust adhesion effect.

[0026] See Figures 1-4One side of the bracket 1 has two through holes 15 symmetrically arranged about the cylinder 11. A guide rod 19 is inserted into each through hole 15, and a bushing 20 is installed at one end of each guide rod 19. The two bushings 20 are respectively fitted onto both ends of the support shaft 4. A straight cylinder 12, concentrically arranged with the through hole 15, is located at the end of the through hole 15 away from the bushing 20. One end of the straight cylinder 12 is connected and fixed to the bracket 1. A disc 18 is installed at the end of the guide rod 19 inside the straight cylinder 12. A spring 21 is located on the side of the disc 18 away from the guide rod 19, and the spring 21 is arranged along the length of the straight cylinder 12. A detachable cap 14 is installed at the end of the straight cylinder 12 away from the bracket 1. A cap 14 is fitted onto the end of the straight cylinder 12 away from the bracket 1 and is connected and fixed to the end of the straight cylinder 12. A fixed connecting ring 13 is used to connect the connecting ring 13 to the cylinder cover 14 through multiple sets of bolts, completing the assembly of the cylinder cover 14 and the straight cylinder 12. The two ends of the spring 21 are in contact with the disc 18 and the cylinder cover 14 respectively, so that the two bushings 20 are respectively sleeved on the two ends of the support shaft 4. The interaction between the rolled dust-adhesive tape 7 and the dust-adhesive roller 6 causes the spring 21 to be in a compressed state in the initial state. When the diameter of the dust-adhesive tape 7 on the support shaft 4 gradually shortens due to use, under the action of the spring 21's rebound force, the support shaft 4 moves along the elongated opening 5 through the transmission of the disc 18, guide rod 19 and bushing 20, so that the dust-adhesive tape 7 on the support shaft 4 is always in contact with the dust-adhesive roller 6 until the dust-adhesive tape 7 on the support shaft 4 is used up.
