Description

Technical Field

[0001] The utility model relates to the technical field of non-woven fabric processing, in particular to a punching device for non-woven fabric processing. Background Art

[0002] As is well known, non-woven fabric, also known as non-woven cloth, needle-punched cotton, needle-punched non-woven fabric, etc., is produced from polyester fiber and polyester fiber (abbreviation: PET) materials and is made through a needle-punching process. It can be made into different thicknesses, hand feelings, hardnesses, etc. It is widely used in automobiles. When processing automotive non-woven fabrics, symmetrical punching processing is required.

[0003] Existing non-woven fabric processing devices often use a single punching device to punch materials, which easily leads to uneven quality when processing two groups of materials that need to be symmetrically processed. At the same time, when punching, the fabric is pressed, and wrinkles are likely to occur, resulting in poor punching quality. It is not very convenient to use. Summary of the Utility Model

The position adjustment component includes a U-shaped support frame, a lifter, a lifting plate, a motor, a left-right threaded screw, a sliding frame, and a slider. The two free ends of the support frame are arranged on the workbench. The output end of the lifter penetrates through the center of the top wall of the support frame and is connected to the lifting plate. A sliding frame is arranged below the lifting plate. A left-right threaded screw and two groups of symmetrically arranged sliders are arranged inside the sliding frame. The output end of the motor penetrates through the side wall of the sliding frame and is connected to the left-right threaded screw. The slider is threadedly connected to the left-right threaded screw. The punching component includes an elastic member, a tensioning plate, and a punching tube. The punching tube is arranged below the slider. Elastic members are arranged at the four corners below the lifting plate. The four corners of the upper part of the tensioning plate are connected to the elastic members. Tensioning holes adapted to the punching tube are arranged on the tensioning plate. A support plate is also arranged on the workbench.

[0008] To facilitate the stable support of the tensioning plate, the utility model is improved in that the elastic member includes a telescopic rod, a spring, and a retaining ring. The upper and lower ends of the telescopic rod are respectively connected to the top wall of the lifting plate and the tensioning plate. The fixed end of the telescopic rod is provided with the retaining ring. The upper and lower ends of the spring are respectively connected to the retaining ring and the tensioning plate.

[0009] Preferably, the motor is a servo motor.

[0010] Preferably, the lifter adopts a hydraulic cylinder.

[0011] Preferably, legs are provided at the four lower corners of the workbench.

[0012] (III) Beneficial effects

[0013] Compared with the prior art, the utility model provides a punching device for non-woven fabric processing, which has the following beneficial effects:

[0014] The punching device for non-woven fabric processing drives the forward and reverse thread screws to rotate through a motor, and two sets of slide blocks move toward each other in a slide frame. A punching tube is also provided under the slide block. As the lifter drives the slide frame to descend, the two sets of symmetrically arranged punching tubes punch holes stably, and then cooperate with a tensioning plate with elastic parts to facilitate stable punching of the material.
