[0002] Hard felt is a kind of felt material with high hardness and strength, and its material covers carbon fiber, silicon carbide fiber, wool and polyester fiber.

[0003] When cutting or punching the hard felt, it is directly placed on the table top of the cutting device or the punching device, which may cause movement during cutting or punching, resulting in deviation of cutting or punching. Moreover, due to the adhesion of the bottom of the hard felt to the top of the table, the hard felt usually needs to be slid outward from the edge to the outside of the table when being taken off, which is extremely inconvenient. SUMMARY

[0005] The utility model provides the following technical scheme: a hard felt processing frock, which comprises a fixing seat, an air pump and an electromagnetic valve are fixedly installed on the outer wall of the fixing seat, a telescopic block and a top block are slidably connected to the inner wall of the fixing seat, a limiting rod is fixedly installed on the inner wall of the fixing seat, a limiting plate is fixedly installed on the inner wall of the fixing seat, a limiting column is fixedly installed on the top of the limiting plate, an extension plate is fixedly installed on the outer wall of the top block, a spring one is arranged on the top of the extension plate, a motor is fixedly installed on the outer wall of the fixing seat, a double-head screw rod is fixedly installed on the output shaft of the motor, a sliding plate is fixedly installed on the bottom of the telescopic block, a spring two is arranged on the inner wall of the telescopic block, a pressing plate is slidably connected to the inner wall of the telescopic block, a telescopic head is fixedly installed on the outer wall of the pressing plate, and a fixed wheel is rotatably connected to the bottom of the telescopic head.

[0006] As a preferred technical scheme of the utility model: the double-head screw rod penetrates the sliding plate, and the double-head screw rod is threadedly connected with the sliding plate.

[0007] As a preferred technical scheme of the utility model: the shape of the pressing plate is the same as that of the inner wall of the telescopic block, and the pressing plate is attached to the inner wall of the telescopic block.

[0008] As a preferred technical scheme of the utility model: the number of limiting rods is two, and the two limiting rods are symmetrically arranged, and the two limiting rods penetrate the top of the telescopic block.

[0009] As a preferred technical solution of this utility model: the size of the extension plate is adapted to the size of the limiting plate, the extension plate is located above the limiting plate, and the limiting post penetrates the extension plate.

[0010] As a preferred technical solution of this utility model: the number of the sliding plate, telescopic block, spring two, pressure plate, telescopic head and fixed wheel is two, and the two sliding plates, telescopic blocks, spring two, pressure plates, telescopic heads and fixed wheels are symmetrically arranged.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The tooling for processing rigid felt involves starting a motor, which drives a double-ended lead screw to rotate. The two sliding plates of the double-ended lead screw move towards the center, causing the two springs, pressure plate, telescopic head, and fixed wheels to move towards the center. This causes the two fixed wheels to come into contact with the outer wall of the rigid felt at the top of the fixed seat. As the movement continues, the fixed wheels continue to compress the rigid felt, which in turn causes the fixed wheels to drive the telescopic head and pressure plate towards the springs, compressing the springs. This, in turn, fixes the rigid felt to the fixed wheels on both sides, reducing the possibility of the rigid felt shifting.

[0013] 2. The tooling for processing rigid felt, through the fit between the extension plate and the inner wall of the fixed seat, forms a seal between the extension plate and the fixed seat, preventing gas from reaching the top of the extension plate. When the air pump is started, the air pump delivers gas to the bottom of the top block and the extension plate, causing the gas to push the top block and the extension plate upwards. This causes the top block to leak out from the surface of the fixed seat, lifting the rigid felt. The activation of the solenoid valve allows the gas at the bottom of the top block to be discharged, and the spring returns to reset the structure. Thus, the rigid felt is lifted up first when it is removed. Attached Figure Description
