Description

Technical Field

[0001] This utility model relates to the field of copper and aluminum foil trimming technology, specifically a copper and aluminum foil trimming device. Background Technology

[0002] Trimming copper and aluminum foil is a key process in the production or processing of metal foils such as copper and aluminum foils. It refers to the trimming of the foil edges using specialized equipment to remove burrs, rough edges, wavy edges, or irregular edges generated during the rolling and slitting processes. This ensures that the foil edges are flat, smooth, and meet the preset specifications. This process not only improves the appearance quality of the foil but also reduces equipment wear, material waste, or product performance problems caused by edge defects in subsequent processing. It is an important process step to ensure the dimensional accuracy and reliability of metal foils.

[0003] Existing copper and aluminum foil trimming equipment has a relatively fixed blade spacing design, making it difficult to flexibly adjust the cutting range according to the actual width deviation, thickness fluctuation, or characteristics of different batches of foil. This results in an unstable matching of the relative position between the blade and the edge of the foil during the trimming process, leading to uneven trimming width. In some areas, the blade may not fully cover the excess material, or the blade may be too close to the effective area, causing over-cutting. This seriously affects the dimensional accuracy and material utilization of the foil. To address this, we propose a copper and aluminum foil trimming device. Utility Model Content

[0004] The purpose of this invention is to provide a copper and aluminum foil trimming device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a copper-aluminum foil trimming device, comprising a base plate, a plurality of fixed plates fixedly connected to the surface of the base plate, and a roller rotatably connected to one side of each of the fixed plates, a motor fixedly connected to one end of the roller, the motor being fixedly connected to the surface of the fixed plates, copper-aluminum foil bodies mounted on the surfaces of two rollers, a trimming structure provided on the surface of the base plate, the trimming structure comprising a U-shaped plate fixedly connected to the surface of the base plate, a threaded rod rotatably connected to the surface of the U-shaped plate, a drive plate threadedly connected to the surface of the threaded rod, a plurality of circular holes opened on the surface of the drive plate, two rectangular tubes sleeved on the surface of the drive plate, pins slidably inserted into the surface of the rectangular tubes, the size of the pins matching the size of the circular holes, and a blade fixedly connected to the side of the rectangular tubes near the U-shaped plate.

[0006] The effect achieved by the above components is that by setting the trimming structure, the copper and aluminum foil can be accurately trimmed, avoiding over-cutting and thus reducing waste of copper and aluminum foil.

[0007] Preferably, an extension arm is fixedly connected to one side of the rectangular tube, and a roller is rotatably connected to the end of the extension arm away from the rectangular tube.

[0008] The effect achieved by the above components is as follows: the roller at the end of the extension arm on one side of the tube contacts the surface of the copper and aluminum foil body. As the foil moves, the roller rolls and presses and guides the foil, preventing the foil from shifting or wrinkling during trimming, thus ensuring the stability of cutting and the quality of trimming.

[0009] Preferably, a spring is fitted onto the arc surface of the pin, and the two ends of the spring are fixedly connected to the pin and the rectangular tube, respectively.

[0010] The effect achieved by the above components is that the spring restores its deformation and drives the pin to insert into the corresponding round hole. The spring improves the stability of the pin inserted into the round hole, thereby preventing the pin from coming out of the round hole due to shaking.

[0011] Preferably, a turntable is fixedly connected to the end of the threaded rod away from the U-shaped plate, and the cross-section of the turntable is in the shape of a cross.

[0012] The effect achieved by the above components is that rotating the cross-shaped turntable causes the threaded rod to rotate on the surface of the U-shaped plate, and the turntable facilitates the rotation of the threaded rod.

[0013] Preferably, a limiting rod slides through the surface of the drive plate, and the limiting rod is fixedly connected to the surface of the U-shaped plate.

[0014] The effect achieved by the above components is that the limiting rod restricts the movement path of the drive plate, thereby preventing the drive plate from rotating during movement.

[0015] Preferably, a plurality of extension plates are fixedly connected to the surface of the base plate, and two guide rods are fixedly connected to the side of each of the two extension plates that are close to each other, and the two guide rods are respectively located on both sides of the copper-aluminum foil body.

[0016] The effect achieved by the above components is that before the copper and aluminum foil body enters the trimming structure, it will first pass through the guide rods on the extension plate. The guide rods on both sides play a role in pre-positioning and guiding the foil, ensuring the stability of the copper foil during the transportation process.

[0017] Preferably, the arc surface of the guide rod is fitted with a cylinder.

[0018] The effect achieved by the above components is that the cylindrical sleeve on the arc surface of the guide rod converts the sliding friction between the foil and the guide rod into rolling friction, reducing wear on the foil surface and making the foil conveying smoother.

[0019] Compared with the prior art, the beneficial effects of this utility model are: This utility model, by setting an edge trimming structure, achieves the adjustment of the two blades to a suitable thickness and spacing. As the copper and aluminum foil body is continuously conveyed, when it passes through the edge trimming structure, the blades on both sides will cut the edge of the foil to remove defects such as burrs and rough edges, thereby accurately trimming the copper and aluminum foil, avoiding over-cutting, and thus reducing the waste of copper and aluminum foil.

Detailed Implementation

[0022] 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.

[0023] Please see Figure 1-2This utility model provides a technical solution: a copper and aluminum foil trimming device, including a base plate 1, a plurality of fixing plates 2 fixedly connected to the surface of the base plate 1, and a roller 3 rotatably connected to one side of each fixing plate 2 that is close to each other. A motor 4 is fixedly connected to one end of the roller 3, and the motor 4 is fixedly connected to the surface of the fixing plates 2. Copper and aluminum foil bodies 5 are mounted on the surface of two rollers 3. The surface of the base plate 1 is provided with a trimming structure 6, which includes a U-shaped plate 601 fixedly connected to the surface of the base plate 1, and a threaded rod rotatably connected to the surface of the U-shaped plate 601. 602, a drive plate 603 is threadedly connected to the surface of the threaded rod 602. Several round holes 604 are opened on the surface of the drive plate 603. Two rectangular tubes 605 are fitted on the surface of the drive plate 603. Pins 606 are slidably inserted into the surface of the rectangular tubes 605. The size of the pins 606 is adapted to the size of the round holes 604. A blade 607 is fixedly connected to the side of the rectangular tube 605 near the U-shaped plate 601. By setting the trimming structure 6, the copper and aluminum foil can be accurately trimmed, avoiding over-cutting and reducing the waste of copper and aluminum foil.

[0024] Reference Figure 3-5As shown in this embodiment: an extension arm 608 is fixedly connected to one side of the rectangular tube 605. A roller 609 is rotatably connected to the end of the extension arm 608 away from the rectangular tube 605. The roller 609 at the end of the extension arm 608 on one side of the rectangular tube contacts the surface of the copper-aluminum foil body 5. As the foil moves, the roller 609 rolls and presses and guides the foil, preventing the foil from shifting or wrinkling during trimming, ensuring the stability of cutting and the quality of trimming. A spring 610 is fitted on the arc surface of the pin 606. The two ends of the spring 610 are fixedly connected to the pin 606 and the rectangular tube 605, respectively. The spring 610 returns to its original shape and drives the pin 606 to insert into the corresponding round hole 604. The spring 610 improves the stability of the pin 606 inserted into the round hole 604, thereby preventing the pin 606 from coming out of the round hole 604 due to shaking. A turntable 611 is fixedly connected to the end of the threaded rod 602 away from the U-shaped plate 601. The cross-section of the turntable 611 is cross-shaped. Rotating the cross-shaped turntable 611 causes the threaded rod 602 to rotate on the surface of the U-shaped plate 601, thus facilitating the rotation of the threaded rod 602. A limit rod 612 slides through the surface of the drive plate 603. The limit rod 612 is fixedly connected to the surface of the U-shaped plate 601, thus restricting the movement path of the drive plate 603 and preventing the drive plate 603 from rotating during movement. Several extension plates 613 are fixedly connected to the surface of the base plate 1. Two guide rods 614 are fixedly connected to the side of each extension plate 613 that is close to each other. The two guide rods 614 are located on both sides of the copper-aluminum foil body 5. Before entering the trimming structure 6, the copper-aluminum foil body 5 passes through the guide rods 614 on the extension plate 613. The guide rods 614 on both sides play a role in pre-positioning and guiding the foil, ensuring the stability of the copper foil during the conveying process. A cylinder 615 is fitted on the arc surface of the guide rod 614. The cylinder 615 fitted on the arc surface of the guide rod 614 converts the sliding friction between the foil and the guide rod 614 into rolling friction, reducing wear on the foil surface and making the foil conveying smoother.

[0025] Working principle: When trimming the copper-aluminum foil body 5, the operator first rotates the cross-shaped turntable 611, causing the threaded rod 602 to rotate on the surface of the U-shaped plate 601. Because the drive plate 603 is threadedly connected to the threaded rod 602, and under the constraint of the limiting rod 612, the drive plate 603 moves axially along the threaded rod 602, thereby causing the rectangular tube 605 and the blade 607, which are sleeved on the drive plate 603, to move as a whole. This initially adjusts the relative position of the blade 607 to the edge of the copper-aluminum foil body 5, adapting to the approximate trimming requirements of foils of different thicknesses. After adjusting the thickness, pull the pin 606 outward to disengage it from the current circular hole 604. At this time, the spring 610 is stretched, and the rectangular tube 605 slides on the drive plate 603. When the blade 607 moves to the ideal trimming position, release the pin 606. The spring 610 returns to its original deformation and drives the pin 606 to insert into the corresponding circular hole 604, fixing the rectangular tube 605 to the drive plate 603. This completes the precise adjustment of the blade 607 spacing, ensuring accurate matching between the blade and the foil edge. Then, after the device is started, the motor 4 fixed on the surface of the fixing plate 2 begins to run. The output shaft of motor 4 drives the reel 3 to rotate. Since the copper-aluminum foil body 5 is wound around the surfaces of the two reels 3, the rotation of the reels 3 drives the copper-aluminum foil body 5 to move from one reel 3 to the other, realizing continuous conveying of the foil. As the copper-aluminum foil body 5 is continuously conveyed, when it passes through the trimming structure 6, the blades 607 on both sides will cut the edge of the foil to remove defects such as burrs and rough edges. During the cutting process, the roller 609 at the end of the extension arm 608 on one side of the rectangular tube 605 contacts the surface of the copper-aluminum foil body 5. As the foil moves, the roller 609 rolls and... The foil material serves to compress and guide, preventing it from shifting or wrinkling during trimming, thus ensuring the stability of the cut and the quality of the trimming. Before entering the trimming structure 6, the copper and aluminum foil body 5 passes through the guide rods 614 on the extension plate 613. The guide rods 614 on both sides pre-position and guide the foil material, ensuring the stability of the copper foil material during the conveying process. The cylindrical tube 615 fitted on the arc surface of the guide rod 614 converts the sliding friction between the foil material and the guide rod 614 into rolling friction, reducing wear on the foil material surface and making the foil material conveying smoother.
