[0004] The above patent has the following defects: in the above patent, when unwinding the strip, the squeezing roller squeezes the strip by the elastic force of the spring to form friction to prevent the strip from loosening. Due to the inertia of the strip when it is released, the squeezing roller may continue to rotate for a short distance until the friction between the strip and the device cylinder reaches a balance. Excessive release of the strip may cause stretching deformation or surface scratches. For this reason, an unwinding structure applied to a strip continuous electroplating device is proposed. Utility Model Content

[0005] The utility model aims to provide an unwinding structure applied to a strip material continuous electroplating device to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an unwinding structure applied to a strip material continuous electroplating device, comprising an operating table, a strip material body for the continuous electroplating device is arranged on the top of the operating table, a clamping assembly is arranged on one side of the strip material body, and a pushing assembly is arranged on one side of the clamping assembly;

[0007] The clamping assembly includes a placement plate, a brake disc is fixed to the bottom of the placement plate, a first slide groove is opened on one side of the top of the placement plate, an inner wall of the first slide groove is rotatably connected to a screw rod through a bearing, a turntable is fixed to one end of the screw rod, a bolt is threadedly connected to one side of the turntable, a circular disc is fixed to the outer side of the surface of the placement plate, and a clamping plate slidably connected to the inner side of the first slide groove is threadedly connected to the outer side of the screw rod.

[0008] Preferably, there are two clamps, and the outer sides of the clamps are attached to the inner side walls of the strip body.

[0009] Preferably, the surface of the screw rod is provided with two threaded sections in opposite directions, the bottom of the brake disc is rotatably connected to the top of the operating table via a rotating shaft, and one end of the bolt is fitted to one side of the disc.

[0010] Preferably, the pushing assembly comprises a fixed frame, an inner side wall of the fixed frame is provided with a second slide groove, an inner side of the second slide groove is slidably connected with a slide plate, and a plurality of springs are connected between one side of the slide plate and the inner side of the second slide groove.

[0011] Preferably, a plurality of second connecting rods are fixed to one side of the slide plate, a limiting frame is fixed to one end of the second connecting rod, and a second rubber roller is rotatably connected between the limiting frames via a bearing.

[0012] Preferably, a first rubber roller located on one side of the second rubber roller is rotatably connected to one side of the top of the operating table through a bearing, and the outer side of the strip body is respectively wound around the outer sides of the first rubber roller and the second rubber roller.

[0014] Compared with the prior art, the utility model adopts the above technical solution and has the following technical effects:

[0015] 1. The screw rod is driven to rotate by rotating the turntable, and the screw rod is threadedly connected to the clamping plate, so that the two clamping plates slide on the inside of the first slide groove. When the two clamping plates fit the inner wall of the strip body, the bolt is rotated at this time so that one end of the bolt abuts against one side of the disc to prevent the clamping plate clamping the strip body from loosening. The turntable is rotated at different angles to make the distance between the two clamping plates different. At this time, strip bodies of different diameters can be clamped and fixed. The operation is simple and convenient, which improves the versatility of the unwinding structure when used.

[0016] 2. When the strip body is not pulled by the continuous electroplating device, the second rubber roller is pushed to one side under the elastic force of multiple springs, so that the brake pad is attached to the surface of the brake disc. When the continuous electroplating device is not pulling the strip body, the rotation of the placement disc can be quickly stopped to prevent the strip body from releasing too much strip body due to inertia, thereby realizing the automatic braking function. There is no need for manual intervention in the braking process, which can avoid the strip body from releasing too much inertia, causing tensile deformation or surface scratches, thereby protecting the quality of the strip body.

[0030] See also Figure 1-5 The utility model provides a technical solution: an unwinding structure applied to a strip material continuous electroplating device, comprising an operating table 1, a strip material body 5 for the continuous electroplating device is arranged on the top of the operating table 1, a clamping component 2 is arranged on one side of the strip material body 5, and a pushing component 3 is arranged on one side of the clamping component 2;

[0031] In order to facilitate the clamping and fixing of the strip body 5 with different diameters, a clamping assembly 2 is provided, which includes a placement plate 21, a brake disc 24 is fixed to the bottom of the placement plate 21, a first slide groove 28 is opened on one side of the top of the placement plate 21, and a screw rod 25 is rotatably connected to the inner wall of the first slide groove 28 through a bearing, a turntable 23 is fixed to one end of the screw rod 25, and a bolt 26 is threadedly connected to one side of the turntable 23. The bolt 26 is rotated so that one end of the bolt 26 abuts against one side of the disc 27 to prevent the clamping plate 22 clamping the strip body 5 from loosening, a disc 27 is fixed to the outer side of the surface of the placement plate 21, and a clamping plate 22 slidably connected to the inner side of the first slide groove 28 is threadedly connected to the outer side of the screw rod 25, and the number of the clamping plates 22 is two. The outer side of the clamping plate 22 is attached to the inner wall of the strip body 5, and the turntable 23 drives the screw rod 25 to rotate, and the screw rod 25 is threadedly connected to the clamping plate 22, so that the two clamping plates 22 slide on the inner side of the first slide groove 28. When the two clamping plates 22 are attached to the inner wall of the strip body 5, two threaded sections in opposite directions are provided on the surface of the screw rod 25. The bottom of the brake disc 24 is rotatably connected to the top of the operating table 1 through the rotating shaft, and one end of the bolt 26 is attached to one side of the disc 27. The strip body 5 is respectively connected to the outer sides of the first rubber roller 31 and the second rubber roller 32. By rotating the turntable 23 at different angles, the spacing between the two clamping plates 22 is different. At this time, the strip bodies 5 of different diameters can be clamped and fixed.

[0032] In order to prevent the strip body 5 from unwinding due to inertia, a pushing component 3 is provided, which includes a fixed frame 33, an inner wall of the fixed frame 33 is provided with a second slide groove 6, and a slide plate 37 is slidably connected to the inner side of the second slide groove 6. The pulling force causes the second rubber roller 32 to push the limiting frame 310, the second connecting rod 35, the slide plate 37 and the first connecting rod 34 to move to one side. At the same time, the first connecting rod 34 drives the second connecting rod 35 and the brake pad 36 to leave the outer side of the brake disc 24. At this time, the strip can be unwound normally. A number of springs 38 are connected between one side of the slide plate 37 and the inner side of the second slide groove 6. A number of second connecting rods 35 are fixed to one side of the slide plate 37. A limit frame 310 is fixed at one end of the connecting rod 35, and a second rubber roller 32 is rotatably connected between the limit frame 310 through a bearing. When the continuous electroplating device does not pull the strip body 5, the second rubber roller 32 is pushed to one side under the elastic force of multiple springs 38, so that the brake pad 36 is attached to the surface of the brake disc 24. At this time, when the continuous electroplating device does not pull the strip body 5, the rotation of the placement plate 21 can be quickly stopped. A first rubber roller 31 located on one side of the second rubber roller 32 is rotatably connected to one side of the top of the operating table 1 through a bearing, and the outer sides of the strip body 5 are respectively connected to the outer sides of the first rubber roller 31 and the second rubber roller 32.

[0033] A first connecting rod 34 is fixed to the side of the slide plate 37 away from the second connecting rod 35, a second connecting rod 35 is fixed to the side of the first connecting rod 34, a brake pad 36 adapted to the outer side of the brake disc 24 is fixed to the side of the second connecting rod 35, and the bottom of the fixing frame 33 is fixed to the top side of the operating table 1. When the continuous electroplating device does not pull the strip body 5, the brake pad 36 can be attached to the surface of the brake disc 24 under the elastic force of the spring 38, so as to quickly stop the rotation of the placement plate 21, avoiding the strip body 5 from releasing too much strip due to inertia, realizing the automatic braking function, and no manual intervention in the braking process is required.

[0034] Working principle: when it is necessary to unwind the strip body 5 used in the continuous electroplating device, the rolled strip body 5 is placed on the top of the placing disk 21, and then the turntable 23 is rotated according to the diameter of the rolled strip body 5, and the turntable 23 drives the screw rod 25 to rotate, and the screw rod 25 is threadedly connected with the clamping plate 22, so that the two clamping plates 22 slide inside the first slide groove 28, and when the two clamping plates 22 are in contact with the inner wall of the strip body 5, the bolt 26 is rotated at this time so that one end of the bolt 26 abuts against one side of the disc 27 to prevent the clamping plates 22 clamped by the strip body 5 from loosening, and then the strip body 5 is respectively wound around the outside of the first rubber roller 31 and the second rubber roller 32, and the spacing between the two clamping plates 22 is different by rotating the turntable 23 at different angles, so that the strip bodies 5 with different diameters can be clamped and fixed, the operation is simple and convenient, and the versatility of the unwinding structure when in use is improved;

[0035] When the strip body 5 is unwinding, the continuous electroplating device will pull the strip body 5. At this time, the pulling force causes the second rubber roller 32 to push the limit frame 310, the second connecting rod 35, the slide plate 37 and the first connecting rod 34 to move to one side. At the same time, the first connecting rod 34 drives the second connecting rod 35 and the brake pad 36 to leave the outside of the brake disc 24. At this time, the placement plate 21 and the brake disc 24 begin to rotate, and the strip body 5 can start to unwind. When the continuous electroplating device does not pull the strip body 5, at this time, under the elastic force of multiple springs 38, the second rubber roller 32 is pushed to move to one side, and the brake pad 36 is attached to the brake disc 24. When the continuous electroplating device does not pull the strip body 5, the brake pad 36 can be attached to the surface of the brake disc 24 under the elastic force of the spring 38, thereby quickly stopping the rotation of the placement disk 21, avoiding the strip body 5 from releasing too much strip due to inertia, realizing the automatic braking function, without the need for manual intervention in the braking process, avoiding the strip body 5 from releasing too much inertia, causing tensile deformation or surface scratches, etc., thereby protecting the quality of the strip body.
