[0016] The oblique openings are arranged to facilitate the material frame to enter the frame, the clamping blocks and the clamping block pins are arranged to fixedly connect the material frame with the frame, and relative movement of the material frame relative to the frame during movement is avoided.

[0017] As a further scheme of the present application: a bottom bar for increasing the strength of the bottom plate is arranged at the lower end of the material frame bottom plate, a friction plate is detachably connected to the lower end of the material frame bottom plate, and the friction plate is arranged in cooperation with the first short friction bar.

[0018] The direction of the friction plate is perpendicular to the direction of the rollers, and the lower bottom surface of the friction plate is lower than the bottom plate and the bottom bar, when the material frame slides on the rollers, the friction plate directly contacts the rollers and rolls on the rollers, thereby avoiding the rollers and the bottom plate or the bottom bar from being contacted and rubbed to cause abrasion of the two, and when the friction plate is damaged, the friction plate can be directly replaced, thereby facilitating disassembly and replacement.

[0019] As a further solution of the present invention: a plurality of jig spaces for accommodating the jig are set on the material frame bottom plate, each of the jig spaces is provided with a plurality of positioning pins fixedly connected to the material frame bottom plate, and the lower end of the jig is provided with a guide sleeve that cooperates with the positioning pin, and the positioning pin is inserted into the guide sleeve.

[0020] The guide sleeve is a hollow round sleeve with a fixed inclined surface at the bottom that is smaller at the top and larger at the bottom. The positioning pin has a smaller upper end and a larger lower end, which facilitates the inner hole of the guide sleeve and the positioning pin to fit into each other.

[0021] As a further solution of the present invention: the jig includes a frame plate, the frame plate includes a sealing plate of the bottom plate and side plates arranged at both ends of the sealing plate, the sealing plate is fixedly connected to the jig bottom plate, the jig bottom plate and the side plates are provided with pins for fixing the jig bottom plate, and a connecting plate is provided between the side plate and the jig bottom plate.
