Description

Shaped leather shell folding mechanism

technical field

The utility model relates to a special-shaped leather shell folding mechanism, which is applied to leather shell cover packaging equipment, and is especially aimed at the irregular shape of the folding edge.

Background technique

At present, the hemming of the cover of the leather shell machine packaging mainly adopts belt twisting and deformation, and uses the twisting of the belt to make the surface paper edge flanging and bonding, and the belt twisting and deformation method cannot be used to hem the triangular, circular, and elliptical edges. The hemming of irregular-shaped edges can only be hemmed manually, which is not suitable for mass production regardless of speed, efficiency, and time.

Utility model content

In view of the technical problems existing in the background technology, the technical problem solved by the utility model is to provide a special-shaped leather shell hemming mechanism.

In order to solve the above-mentioned technical problems, the utility model adopts the following technical scheme: the hemming mechanism of the special-shaped leather shell includes a frame, a fixed mold and a movable mold, and it is characterized in that: the fixed mold and the movable mold have the same shape as the hemming respectively. Matching working sides, the working sides of the fixed mold and the movable mold are set opposite to each other, the fixed mold is fixedly set on the frame, and the movable mold is set on the frame to move up and down and move laterally.

The frame is also provided with a positioning device and a paper pressing device.

The movable mold is arranged on the push plate through the lifting cylinder, the push plate is connected with the horizontal cylinder transmission and the push plate is driven laterally on the frame by the horizontal cylinder.

The push plate is arranged on the transverse guide rail of the frame, and a linear guide shaft and a shaft sleeve are arranged between the movable mold and the push plate.

The push plate is also provided with a buffer post and a buffer pad, and the buffer pad is arranged on the top of the buffer post.

The movable mold is connected with the linear guide shaft by setting the installation bar.

The work of the movable mold moves up and down while sticking to the work of the fixed mold.

The beneficial effect of the utility model is that the new hemming mechanism can perform hemming operations on irregularly shaped hemmings (such as triangular sides, circular sides, elliptical sides) and flat straight line hemmings, and solves the problem that the twisting and deformation of the belt cannot be corrected. The problem of edge folding of special-shaped edges is the premise of realizing mechanized operation, so the utility model has substantive characteristics and progress compared with the prior art.

detailed description

Referring to the accompanying drawings, the special-shaped leather shell folding mechanism in the present embodiment includes a frame, a fixed mold 0 and a movable mold 3, and the fixed mold and the movable mold have respectively working edges matched with the shape of the flange (that is, the shape of the flange is In the case of special-shaped sides, the fixed mold and the movable mold also have sides that match the special-shaped sides. Of course, the shape of the folded edges can also be a straight line). On the frame, the movable mold is set on the frame to move up and down and move laterally. The working of the moving mold moves up and down while sticking to the working of the fixed mold.

The frame is also provided with a positioning device and a paper pressing device. The positioning device includes a photoelectric sensor, and the photoelectric sensor is electrically connected to the conveyor belt of the paper feeding device. When the gray cardboard and the face paper are pasted and sent to the paper folding station, the positioning device transmits a signal to make the paper feeding device stop conveying. The paper pressing device includes a paper pressing cylinder and a pressing board. The paper pressing cylinder and the pressing board are connected by transmission. The gray cardboard and face paper at the folding station will be pressed by the pressing board, so that the gray board and face paper are stable at the folding edge. at the workstation.

The lifting movement and the lateral movement of the movable mold are driven by a lifting cylinder and a horizontal cylinder in the present embodiment. Wherein, the movable mold 3 is arranged on the push plate 18 through the lifting cylinder 17, the push plate is connected with the transmission of the horizontal cylinder 27 and the push plate is moved laterally on the frame by the transmission of the horizontal cylinder. The lifting cylinder can adopt a cylinder with adjustable stroke, which can be adjusted according to the thickness of the cardboard. In order to make the lifting movement and lateral movement of the movable mold more stable, the push plate is arranged on the transverse guide rail 19 of the frame in this embodiment, and a linear guide shaft 11 and a bushing 16 are arranged between the movable mold and the push plate. The shaft can slide in the sleeve. Simultaneously, a buffer structure is also provided, wherein a buffer column 9 and a buffer pad 7 are also arranged on the push plate, and the buffer pad is arranged on the top of the buffer column. In order to make things easier for the moving mold, the moving mold is connected with the linear guide shaft by setting the mounting bar 6.

When working, the gray cardboard and the facial paper are pasted and sent to the folding station. The fixed mold and the movable mold are under the gray cardboard and the facial paper. The folding line of the cardboard is between the fixed mold and the movable mold. The facial paper is folded upwards, and the fixed mold can avoid the deformation of the facial paper when it is folded upwards. Then the movable mold moves to the direction of the gray cardboard to wrap the folded facial paper inward, and the movable mold can further compress the facial paper and On the gray cardboard, the mold is finally fixed for reset.
