Problems solved by technology

Existing chain clip devices usually use compression springs or tension springs to drive the clip head. The spring force is restricted by factors such as the size and structure of the chain clip, so it cannot be made to a large elastic force. The diaphragm is easy to come out of the chain clip during stretching
Or, in some cases, because the diaphragm is soft, the clamping force is too large and the diaphragm is clamped, and then it comes out of the chain clip.
[0004] The existing chain clip device has poor applicability to diaphragms. For softer diaphragms, the clamping force cannot be quickly reduced, and for harder diaphragms, the clamping force cannot be quickly increased. The spring must be replaced to change the holding force, the operation is complicated and cannot be adjusted by itself

Embodiment 1

[0029] A film stretching clamp film device, such as figure 1 As shown, it includes an upper clip body 2, a lower clip body 1, a compression spring 9 and a clip head 4 that can move vertically up and down, etc., the upper clip body 2 and the lower clip body 1 are fixedly connected with screws 7, and the clip head 4 is arranged on the upper clip Body 2 lower end. The clamp film device also includes a piston guide rod 5 located in the upper clamp body 2, the lower end of the compression spring 9 is fixed in the lower clamp body 1, and the lower end of the piston guide rod 5 and the upper end of the compression spring 9 act on the clamp downwards and upwards respectively. head 4.

[0030] A loosening washer 8 is also provided between the nut of the screw 7 and the lower clamp body 1 .

[0031] The lower clip body 1 is also provided with a film support pin 6 for supporting the film 14 .

[0032] The clip head 4 is divided into inner end and outer end in the horizontal direction,...

Embodiment 2

[0041] On the basis of the clip film device described in embodiment 1, as image 3 As shown, a vertical groove 12 is formed on the upper surface of the lower clamp body 1 between the thickness measuring sensor 11 and the compression spring 9;

[0042] The film clamping method is as follows: throw the head of the film 14 into the groove 12, and use the compression screw 13 to go deep into the groove 12 to compress the film 14, so that the film 14 can be directly fixed and compressed, regardless of the clamping force of the subsequent clamping head 4 How, at the cost of sacrificing a small section of film, it is guaranteed that the film 14 will not accidentally fall off during the stretching process.

Abstract

The invention relates to a film stretching film clip device and a film clip method, in particular to a film stretching film clip device with variable clamping force and a film clip method of the filmstretching film clip device. The film clip device comprises an upper clip body, a lower clip body, a compression spring and a clip head capable of vertically moving up and down, the upper clip body and the lower clip body are fixedly connected through a screw, and the clip head is arranged at the lower end of the upper clip body; and the film clip device further comprises a piston guide rod arranged in the upper clip body, the lower end of the compression spring is fixed in the lower clip body, and the lower end of the piston guide rod and the upper end of the compression spring act on the clip head downwards and upwards respectively. Compared with the prior art, the device is simple in structure and operation method, compared with a traditional chain clip device, the clamping force of theclip head to a film can be automatically adjusted without replacing parts, and the adaptability to various soft and hard films is high.

Description

technical field [0001] The invention relates to a film stretching and clamping device, in particular to a film stretching and clamping device with variable clamping force. [0002] The invention also relates to a film clipping method based on the film stretching clipping device. Background technique [0003] The chain clip device is a general-purpose device in the lithium battery separator industry and even other film industries. Its basic function is to fix the film in the film stretching process. Existing chain clamp devices usually use compression springs or tension springs to drive the clamp head. The spring force is restricted by factors such as the size and structure of the chain clamp. During stretching, the diaphragm is easy to come out of the chain clip. Or, in some cases, due to the softness of the diaphragm, the diaphragm is clamped badly due to excessive clamping force, and then comes out from the chain clip. [0004] The existing chain clip device has poor ap...
