Description

Technical Field

[0001] This utility model relates to a needle-punched nonwoven fabric production equipment, belonging to the field of needle-punched nonwoven fabric technology. Background Technology

[0002] Nonwoven fabric is a type of fabric made by bonding fibers together mechanically, thermally, or chemically. Unlike traditional textiles, it is not made through weaving or knitting processes. Nonwoven fabrics are typically made from synthetic fibers such as polypropylene (PP), polyester (PET), and polyethylene (PE), or natural fibers. Some specific products require perforated nonwoven fabrics; when creating these perforations, needles are used to pierce the fabric.

[0003] However, in existing technologies, when needle-punching nonwoven fabrics, the sides of the nonwoven fabric are not pressed and limited. As the needle moves downwards, it exerts a certain amount of pressure on the nonwoven fabric upon contact, causing the sides to shrink inwards, which to some extent affects the needle-punching effect. Therefore, this invention proposes a needle-punched nonwoven fabric production equipment to solve the above problems. Utility Model Content

[0004] Based on the above background, the purpose of this utility model is to provide a needle-punched nonwoven fabric production equipment to solve the problems in the background technology.

[0005] This utility model provides the following technical solution:

[0006] A needle-punched nonwoven fabric production equipment includes several feet, with a working plate on the top of each foot. Each working plate has side plates at both ends. Movable openings are located on both sides of the top of the working plate. The side of the movable opening closest to the side plate is flush with the inner wall of the side plate. A set of first cylinders is located on the outer side of each side plate. The output end of each set of first cylinders passes through the side plate and is located within the movable opening. A connecting plate is fixedly connected to the output end of each set of first cylinders. A bottom plate is located at the bottom of the connecting plate away from the first cylinders. The top surface of the bottom plate is flush with the top surface of the working plate. A top plate is located at the top of the connecting plate away from the first cylinders. A set of dual-axis cylinders is located on the top of the top plate. The output end of each set of dual-axis cylinders passes through the bottom of the top plate. A pressure plate is fixedly connected to the bottom of the output end of each set of dual-axis cylinders. The pressure plate is located between the top plate and the bottom plate, and the end of the pressure plate closest to the side plate slides against the surface of the connecting plate away from the side plate.

[0019] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. In the following detailed description, many specific details are set forth to facilitate explanation and provide a comprehensive understanding of the embodiments of the present invention. However, one or more embodiments may be practiced by those skilled in the art without these specific details.

[0020] like Figure 1 As shown, a needle-punched nonwoven fabric production equipment includes several base feet 1, with a working plate 2 on the top of each base foot 1. Each working plate 2 has side plates 3 at both ends. Movable openings 4 are located on both sides of the top of the working plate 2. The side of the movable opening 4 closest to the side plate 3 is flush with the inner wall of the side plate 3. A set of first cylinders 5 is located on the outer side of each side plate 3. The output end of each set of first cylinders 5 passes through the side plate 3 and is located within the movable opening 4. A connecting plate 6 is fixedly connected to the output end of each set of first cylinders 5. The connecting plate 6 is located away from the first cylinder. A base plate 7 is provided at one end of a cylinder 5. The top surface of the base plate 7 is flush with the top surface of the working plate 2. A top plate 8 is provided at the top of the connecting plate 6 away from the first cylinder 5. A set of dual-axis cylinders 9 is provided at the top of the top plate 8. The output end of the set of dual-axis cylinders 9 extends through the bottom of the top plate 8. A pressure plate 10 is fixedly connected to the bottom of the output end of the set of dual-axis cylinders 9. The pressure plate 10 is located between the top plate 8 and the base plate 7. The end of the pressure plate 10 near the side plate 3 slides against the end of the connecting plate 6 away from the side plate 3.

[0021] In the above technical solution, by setting a first cylinder 5, the first cylinder 5 takes in air and drives the connecting plate 6 to move towards the center of the working plate 2 within the movable opening 4. When the bottom plate 7 moves away from the side plate 3 to abut against the end face of the movable opening 4 away from the side plate 3, the dual-axis cylinder 9 drives the pressure plate 10 to move downward, which can press the two sides of the non-woven fabric between the pressure plate 10 and the bottom plate 7. Then, the first cylinder 5 takes out air and can flatten and limit the non-woven fabric on the top part of the working plate 2 to be needled, thus ensuring the needled effect of the non-woven fabric.

[0022] In this invention, a mounting plate 11 is provided near the top between the side plates 3. A set of second cylinders 12 is provided at the top of the mounting plate 11. The output end of the set of second cylinders 12 extends through the bottom of the mounting plate 11, and a lifting plate 13 is connected to the bottom of the output end of the set of second cylinders 12. Sliding grooves 14 are provided at both ends of the lifting plate 13, and sliding strips 15 are provided on the inner side of the side plates 3. The sliding strips 15 and the sliding grooves 14 are slidably engaged.

[0023] In the above technical solution, the mounting plate 11 can be used to install the second cylinder 12. The lifting plate 13 is provided and the sliding grooves 14 are opened on both sides of the lifting plate 13 to slide and cooperate with the sliding strips 15 on the side plate 3. This facilitates the installation of the needle-punching plate 17 and limits the up and down movement of the lifting plate 13 to ensure the accuracy of non-woven fabric needle punching.

[0024] In this invention, the bottom of the lifting plate 13 is provided with a connecting post 16, and the bottom of the connecting post 16 is detachably connected to a needle-piercing plate 17. A plurality of needles 18 are installed at the bottom of the needle-piercing plate 17, and the needles 18 are rectangularly distributed at the bottom of the needle-piercing plate 17. The top of the working plate 2 has a plurality of piercing holes 19, and each of the piercing holes 19 corresponds one-to-one with a needle 18.

[0025] In the above technical solution, by setting needles 18 at the bottom of the needle plate 17 and setting piercing holes 19 corresponding to the needles 18 at the top of the working plate 2, the non-woven fabric on the top surface of the working plate 2 can be needled during the descent of the lifting plate 13.

[0026] In this utility model, there are four base feet 1, which are distributed at the four corners of the bottom of the working plate 2.

[0027] In the above technical solution, by setting a foot 1 at each of the four corners of the bottom of the working plate 2, the present invention can be supported, thus making the present invention more stable during operation.

[0028] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
