[0019] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0020] In order to better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0021] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0022] Please refer to Figures 1 to 3 The embodiment of the utility model provides a clamping device for strip materials, including a base 100, a clamping mechanism 200 and an opening and closing driving mechanism.

[0023] Specifically, the clamping mechanism 200 includes two clamping plates 210 and at least one action component 220. The clamping plates 210 may have a certain length and width to meet the requirements of grabbing strip materials. The action component 220 is arranged on the base 100. Each action component 220 includes two hinged action members 221. The two action members 221 can rotate relative to each other under the action of an external force. An elastic member is connected between the two action members 221, and the elastic member can apply a force to each action member 221 toward another action member 221. In one example, the elastic member can be a tension spring.

[0024] Thus, in the absence of other external forces, the two action members 221 can remain closed under the action of the elastic member. In addition, the two action members 221 in the same action assembly 220 are respectively connected to a clamping plate 210, so that the clamping plate 210 and the action members 221 can move synchronously.

[0025] The opening and closing drive mechanism includes a telescopic drive member 310 and at least one abutment member 320 that is driven and connected. The telescopic drive member 310 is arranged on the base 100, and the abutment member 320 corresponds one-to-one with the action component 220. Specifically, the abutment member 320 can be arranged between two action members 221, and the abutment member 320 can perform reciprocating linear motion under the drive of the telescopic drive member 310.

[0026] When the abutment member 320 moves toward the two actuating members 221, the ends of the abutment member 320 can respectively abut against the two actuating members 221, thereby expanding the gap between the two actuating members 221, that is, completing the opening action of the clamping plate 210, thereby releasing the clamped strip material or covering the strip material to be clamped. Then, the abutment member 320 can move in a direction away from the two actuating members 221 under the drive of the telescopic driving member 310, and the two actuating members 221 can approach each other under the action of the elastic member, thereby achieving the closure between the two clamping plates 210 and completing the grabbing of the strip material.

[0027] Thus, through the above arrangement, the clamping mechanism 200 includes two clamping plates 210 and at least one action component 220, and the action component 220 is installed on the base 100, and includes two hinged action members 221, and an elastic member is connected between the two action members 221, and the elastic member can apply a force to each action member 221 toward another action member 221, and each action member 221 is respectively connected to a clamping plate 210, thereby, the clamping plate 210 contacts and clamps the strip material, and the contact area between the strip material and the clamping device is increased, which can not only avoid the clamping force from being concentrated at a certain position, reduce the damage to the strip material during clamping, but also ensure the stability of handling;

[0028] Furthermore, the opening and closing driving mechanism includes a telescopic driving member 310 and at least one abutting member 320 that are connected to each other. The abutting member 320 is located between the two action members 221. When the abutting member 320 moves toward each other under the drive of the telescopic driving member 310, its ends can respectively abut against the two action members 221, thereby expanding the gap between the two action members 221, and then driving the clamping plate 210 to open. By cooperating with the abutting member 320 and the elastic member, strip materials of different sizes can be better adapted to prevent strip materials of different sizes from being clamped by the same clamping force, thereby causing damage to the strip materials.

[0029] In one embodiment of the utility model, since the splint 210 has a certain length, in order to ensure the stability of the driving of the splint 210, the number of action components 220 can be multiple. Specifically, the clamping mechanism 200 also includes a first cross bar 230, which is arranged on the base 100. Multiple action components 220 are arranged on the first cross bar 230 at intervals, and the action parts 221 located on the same side are connected to the same splint 210, so that the splint 210 can be driven by multiple action parts 221 to ensure the stability of the splint 210 during operation.

[0030] Correspondingly, the opening and closing driving mechanism includes a second crossbar 330, which is arranged on the base 100, and is arranged parallel to the first crossbar 230. The second crossbar 330 is located between two action members 221 in the same group, and the second crossbar 330 is drivingly connected to the telescopic driving member 310. The telescopic driving member 310 can drive the second crossbar 330 to perform linear reciprocating motion along its axial direction. In one example, the telescopic driving member 310 can be a telescopic cylinder.

[0031] There are also multiple abutment members 320, which are arranged on the second crossbar 330 and correspond to each action assembly 220. Thus, through the above arrangement, based on the telescopic driving member 310, multiple action assemblies 220 can be synchronously driven at the same time, ensuring the stability of clamping, and the structure is simple, reducing the equipment cost.

[0032] In one embodiment of the utility model, each action component 220 can be set on the first cross bar 230 through a bearing. The first cross bar 230 is connected to the inner ring of the bearing, and the action component 220 is connected to the outer ring of the bearing. This can not only reduce the wear of the first cross bar 230 when the action part 221 rotates, but also ensure the stability of the opening and closing of the action part 221.

[0033] In one embodiment of the present invention, the end of each clamping plate 210 has a bent portion facing the other clamping plate 210, so as to better clamp the strip material and prevent the strip material from falling off between the clamping plates 210. It should be noted that the bent portion can be a straight bend or an arc bend, which is not particularly limited.

[0034] In one embodiment of the present invention, the end of the abutment member 320 may be conical or pyramidal, and the inclined surface at the end may better spread the two actuating members 221 apart and reduce the friction therebetween, thereby extending the service life of the device.

[0035] It should be noted that the shape of the abutting member 320 may also be any other shape as long as it can push open the gap between the two actuating members 221 , and there is no special limitation on this.
