Description

Technical Field

[0001] The utility model relates to the technical field of metal sheet coiling and slitting, in particular to a coiling and slitting device. Background Art

[0002] Currently, one manufacturing process for copper alloys involves melting, cooling, and solidifying to form a flat structure. This structure can reach tens of meters in length as it is pulled along the edge. After undergoing multiple processes such as milling and stretching, it is formed into thin sheets and then rolled up. The copper material is cut after each roll reaches the weight standard. During cutting, the copper material is laid flat on a workbench with a cutting blade located in the middle of the workbench's end face. An external cutter cuts into the copper material and forms a shear with the cutting blade to complete the cutting operation. Due to the long transmission distance of the copper material, the copper material is not tensioned enough at the point where the cutter cuts the copper material. The cut of the copper material is easily deformed or displaced by the cutter. Therefore, the cutting action of the cutter needs to be enhanced to ensure the success rate of cutting. This results in the cutter being easily worn and damaged, reducing its service life. Utility Model Content

[0003] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a winding and slitting device that is not prone to yielding, deformation or displacement during cutting, thereby increasing the service life of the cutter.

When the cutter moves downward to form a shear with the blade edge, the pressure block moves downward and its lower end surface presses the upper end surface of the base. When the cutter moves upward to separate from the blade edge, the lower end surface of the pressure block moves upward to move away from the upper end surface of the base.

[0005] Furthermore, it also includes a reel, the blade edge is located between the reel and the pressure block, the distance between the reel center and the blade edge is less than 1000mm, and the shortest distance between the pressure block and the blade edge is less than 300mm.

DETAILED DESCRIPTION

[0019] The following will clearly and completely describe the technical solutions in this embodiment with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] like Figure 1 As shown, a winding and slitting device includes a base 1, a support seat 5, and a cutter 8. The upper end surface of the base 1 is provided with a coil 3, which is a copper alloy and a long sheet structure. The length of the coil 3 is more than tens of meters. The coil 3 is flattened during transmission ( Figure 1 As shown in the direction of the middle arrow, the coil 3 is transported from right to left and is finally wound up by the reel 2. During winding, the reel 2 rotates and tightens the coil 3. When the specified weight is reached, the coil 3 is cut off and the reel on the reel 2 is replaced to continue winding.

[0021] like Figure 1 As shown, the support seat 5 is located above the base 1, and the support seat 5 is provided with two grooves 52, which are spaced apart from each other. The grooves 52 form an opening at the bottom of the support seat 5, and the support seat 5 is equipped with a pressure roller 6. Figure 2 The pressing roller 6 is a cylindrical long strip structure. The pressing roller 6 can rotate along its own axis. Part of the pressing roller 6 is located in the groove 52. The bottom of the pressing roller 6 extends out of the bottom of the groove 52. The bottom of the pressing roller 6 abuts against the upper end surface of the base 1. To be precise, when the upper end surface of the base 1 transmits the coil 3, the bottom of the pressing roller 6 abuts against the coil 3 to prevent the coil 3 from arching during transmission.

[0022] like Figure 1 、 Figure 2 As shown, the pressure roller 6 is fixedly mounted with a shaft 61, which passes through the pressure roller 6. The pressure roller 6 rotates synchronously with the shaft 61. The shaft 61 has support rods 63 mounted on both ends of the shaft 61. The support seat 5 is provided with a countersunk hole 53, which is located above the shaft 61. The upper end of the support rod 63 is inserted into the countersunk hole 53 and the support rod 63 can move up and down along the inner wall of the countersunk hole 53. Specifically, combined with Figure 3 The support rod 63 includes an extension rod 631 at the top. The extension rod 631 is inserted into the countersunk hole 53 and can move up and down along the inner wall of the countersunk hole 53. A limit block 65 is installed at the bottom of the countersunk hole 53. The support rod 63 passes through the limit block 65, and the extension rod 631 is located above the limit block 65. The inner hole of the limit block 65 through which the support rod 63 passes is smaller than the outer diameter of the extension rod 631. A spring 64 is installed in the countersunk hole 53, with the upper end of the spring 64 abutting the upper wall of the countersunk hole 53 and the lower end of the spring 64 abutting the top of the extension rod 631. The shaft body 61 passes through the support rod 63 at both axial ends. The inner wall of the support rod 63 and the outer wall of the shaft body 61 are connected by bearings 62.

[0023] like Figure 1 As shown, the base 1 is provided with a through hole 51, which extends vertically through the base 1. A pressure block 4 is slidably connected to the wall of the through hole 51. The upper end of the pressure block 4 is connected to a driving component 41, which is a cylinder. The driving component 41 drives the pressure block 4 to move up and down. A top plate 7 is mounted on the top end of the base 1, and the driving component 41 is mounted on the top plate 7. The output end of the driving component 41 passes through the top plate 7, and the top plate 7 is located above the pressure block 4.

[0024] The base 1 is provided with a trough 11, the length direction of which is perpendicular to the transmission direction of the coil 3. The trough 11 forms an opening on the upper end face of the base 1, and the trough 11 is provided with a blade 111, which is arranged at the upper end of the right side wall of the trough 11. The support seat 5 is equipped with a knife holder 81, and the knife holder 81 is connected to the driving component 82. The driving component 82 is a cylinder. The knife holder 81 is equipped with a cutter 8, and the blade 111 is arranged opposite to the cutter 8 up and down. The cutter 8 can move up and down under the drive of the driving component 82. When the reel 2 stops reeling, the cutter 8 moves downward to form a shear with the blade 111, cutting the coil 3. At the same time as the coil 3 is cut, the pressure block 4 presses the coil 3 on the upper end face of the base 1 through the pad 42 to prevent the coil 3 from being subjected to the action of the cutter 8 when the coil 3 is cut, causing the coil 3 to yield or displace, thereby affecting the cutting of the cutter 8.

[0025] The blade edge 111 is located between the reel 2 and the pressure block 4. The distance between the center of the reel 2 and the blade edge 111 is less than 1000 mm, and the shortest distance between the pressure block 4 and the blade edge 111 is less than 300 mm. When the coil 3 is cut by the cutter 8, sufficient tension is maintained in the length direction of the coil 3. The cutter 8 cuts the coil 3 in a tensioned state. The coil 3 is not prone to yield deformation, which increases the contact area with the cutter 8. The cutter 8 has less wear and tear, thereby increasing the service life of the cutter 8.

[0026] When the cutter 8 moves upward and separates from the blade edge 111, the pressure block 4 moves upward to move the pad 42 away from the upper end surface of the base 1. At this time, the pressure roller 6 remains in a state of pressing the coil 3, so that when the reel 2 reels the coil 3, the coil 3 maintains tension in the length direction.

[0027] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
