Description

Technical Field

[0001] The utility model relates to the technical field of non-woven fabric processing equipment, in particular to a multi-layer non-woven fabric slitting equipment. Background Art

[0002] Non-woven fabric, also known as non-woven cloth, is composed of oriented or random fibers. It is called cloth because of its cloth appearance and certain properties. Non-woven fabric has the characteristics of moisture-proof, breathable, flexible, light in weight, non-flammable, easy to decompose, non-toxic, non-irritating, rich in colors, low in price, recyclable, etc. For example, it is mostly made of polypropylene pellets as raw materials and produced by a continuous one-step method of high-temperature melting, spinning, laying, and hot-pressing and coiling.

[0003] The non-woven fabric slitting knife is a device for processing non-woven fabric. However, the existing non-woven fabric slitting knife cannot automatically adjust the slitting width of the non-woven fabric, resulting in the user being unable to directly adjust the width to be slit according to the user's needs during the operation of the equipment. The operator needs to stop the equipment and adjust the position of the slitting knife, thus reducing the processing and production efficiency. Therefore, a multi-layer non-woven fabric slitting equipment is proposed to solve this problem. Content of the Utility Model

[0004] In view of this, the utility model provides a multi-layer non-woven fabric slitting equipment, which can drive the driving screw rod to rotate through a driving device, and then enable two connecting sliders to slide along the guiding slide rod, that is, drive the equipment box body and the driving motor in the equipment box body to change positions, so as to change the slitting position of the slitting knife assembly, and then cooperate with the roller shaft structure to automatically adjust the slitting interval without stopping during the slitting operation, improving the production efficiency.

[0005] To solve the above technical problems, the utility model provides a multi-layer non-woven fabric slitting equipment, including an equipment base, on which a slitting structure and a roller shaft structure cooperating with the slitting structure are installed. The slitting structure includes a group of symmetrically arranged equipment box bodies, in which a driving motor is installed. The output end of the driving motor passes through the equipment box body and is fixed with a slitting knife assembly thereon. In addition, a connecting slider is fixed at the lower part of the equipment box body. A driving screw rod and a guiding slide rod are arranged on the equipment base. Corresponding threaded through holes matching the driving screw rod and guiding slide holes matching the guiding slide rod are arranged on the connecting slider. One end of the driving screw rod passes through the equipment base and is in transmission connection with a driving device arranged on one side of it;

[0006] Furthermore, the driving device drives the driving screw rod to rotate, and then enables two connecting sliders to slide along the guiding slide rod, that is, drives the equipment box body and the driving motor in the equipment box body to change positions, so as to change the slitting position of the slitting knife assembly, and then cooperate with the roller shaft structure to automatically adjust the slitting interval without stopping during the slitting operation, improving the production efficiency

[0007] The slitting knife assembly includes a blade body, which is arranged in a disc shape. An installation sleeve is provided at the center position of the blade body. The installation sleeve is arranged in cooperation with the output end of the driving motor, and a fastening member is provided on the installation sleeve;

[0008] Furthermore, the fastening member fixes the installation sleeve to the output end of the driving motor. The driving motor rotates to drive the installation sleeve and the blade body fixed thereon to slit the material.

[0009] The equipment base includes a bottom plate. On the upper base surface of the bottom plate, a set of first mounting seats and a set of second mounting seats are symmetrically provided respectively. The roller shaft structure is installed on the second mounting seats, and the driving lead screw and the guiding slide rod are installed on the first mounting seats;

[0010] Furthermore, the bottom plate is used for connection and installation. During use, the whole is fixed to the working area through the bottom plate. Both the first mounting seat and the second mounting seat play a supporting role. Among them, the first mounting seat is used to support the guiding slide rod and the driving lead screw, and the second mounting seat is used to support the roller shaft structure.

[0011] The roller shaft structure includes a support shaft rotatably installed between two second mounting seats. A roller body that fits with the blade is provided on the support shaft. One end of the support shaft passes through the second mounting seat and is in transmission connection with the driving box provided on this side;

[0012] The roller shaft structure is used to cooperate with the blade body to slit the material. Furthermore, during the slitting operation, the material passes through the gap between the blade body and the roller body, and thus is slit by the blade body.

[0013] The upper edges and corners of the equipment box body are all arranged in a rounded shape;

[0014] Furthermore, during the conveying and slitting process of the material, it is prevented from rubbing against the edges and corners of the equipment box body, thereby ensuring the quality of material production.

[0015] The guiding slide rod and the driving lead screw are arranged at the same horizontal height;

[0016] Furthermore, it can ensure the horizontality of the connection block and the equipment box body, thereby maintaining the normal state of the equipment.

[0017] The beneficial effects of the above technical solutions of the present utility model are as follows:

[0018] The driving device drives the driving lead screw to rotate, so that the two connection sliders can slide along the guiding slide rod, that is, drive the equipment box body and the driving motor in the equipment box body to change positions, so that the slitting position of the slitting knife assembly is changed. Furthermore, when cooperating with the roller shaft structure during the slitting operation, the slitting interval can be automatically adjusted without stopping the machine, improving production efficiency.

[0019] The bottom plate is used for connection and installation. During use, the whole is fixed to the working area through the bottom plate. Both the first mounting seat and the second mounting seat play a supporting role. Among them, the first mounting seat is used to support the guiding slide rod and the driving lead screw, and the second mounting seat is used to support the roller shaft structure.

[0020] The upper edges and corners of the equipment box body are all rounded. During the process of material conveying and cutting, it can avoid rubbing against the edges and corners of the equipment box body, thus ensuring the quality of material production. Description of the Drawings
