Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric technology, specifically to a laminating machine for producing nonwoven fabrics. Background Technology

[0002] Nonwoven fabric is a new type of fiber material that does not require traditional spinning and weaving processes. Its core characteristics are short production process, high efficiency and low cost.

[0003] In the production of nonwoven fabrics, the tensile strength and abrasion resistance are significantly improved and the service life is extended by laminating nonwoven fabrics with molten plastic film. In the existing technology, extrusion casting technology is used to achieve rapid lamination of substrate and plastic layer. However, when coating plastic film, it is impossible to ensure that the nonwoven fabric is always in a taut state, which leads to inconsistent uniformity of plastic film coating. Therefore, we propose a laminating machine for producing nonwoven fabrics. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a coating machine for producing nonwoven fabrics, which solves the problem that the nonwoven fabric cannot be kept taut at all times during plastic film coating, resulting in inconsistent coating uniformity.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] This application provides a coating machine for producing nonwoven fabrics, solving the problem that the nonwoven fabric cannot be kept taut during plastic film coating, resulting in inconsistent coating uniformity. The machine achieves this by having the connecting component 52 push the push rod 56 to move. The push rod 56 moves, causing the connecting frame 53 to move accordingly. The connecting frame 53 then drives the scraper plate 54 to flatten the edge of the nonwoven fabric, preventing incomplete coating at the edges. Simultaneously, the extrusion roller 55 adheres to the nonwoven fabric, tightening it under pressure to prevent folding and ensure uniform plastic film coating, thus improving the finished product quality of the nonwoven fabric.

[0029] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0030] This utility model discloses a coating machine for producing nonwoven fabrics.

[0031] Example 1, according to Appendix Figure 1-3 As shown, it includes a coating machine body 1, and a dryer body 3 is provided on the coating machine body 1. The dryer body 3 is used to dry the film on the nonwoven fabric, quickly dry the coated plastic film, and ensure the uniformity of its forming.

[0032] The main body 1 of the coating machine is equipped with an extrusion unit 5. The extrusion unit 5 is used to stretch the nonwoven fabric to ensure uniform coating of the plastic film. The extrusion unit 5 includes:

[0033] The mounting base 51 is installed on the main body 1 of the coating machine;

[0034] Connecting component 52 is mounted on fixing base 51;

[0035] The connecting frame 53 is located below the fixing base 51. The connecting frame 53 is used to straighten the nonwoven fabric and smooth the edges of the nonwoven fabric to ensure uniform coating of the plastic film and improve the finished product effect of the nonwoven fabric.

[0036] Both sides of the outer wall of the connecting frame 53 are fixedly connected to scraper plates 54. The scraper plates 54 are used to smooth the edges of the nonwoven fabric to ensure that the plastic film is coated evenly.

[0037] A compression roller 55 is rotatably connected to the lower part of the connecting frame 53. The compression roller 55 is used to tighten the nonwoven fabric.

[0038] A push rod 56 is fixedly connected to the top end face of the connecting frame 53, and the upper end of the push rod 56 is connected to the connecting assembly 52.

[0039] The connecting component 52 pushes the push rod 56 to move, and the connecting frame 53 moves accordingly. At this time, the connecting frame 53 drives the scraper plate 54 to scrape the edge of the nonwoven fabric flat, so as to avoid incomplete edge film coating during film coating.

[0040] At the same time, the extrusion roller 55 is in contact with the nonwoven fabric. Under the pressure of the extrusion roller 55, the nonwoven fabric is stretched to prevent folding, ensure uniform coating of the plastic film, and improve the finished product effect of the nonwoven fabric.

[0041] Example 2, according to Appendix Figure 1-3 As shown, the system includes a coating machine body 1, a dryer body 3 mounted on the coating machine body 1, the dryer body 3 being used to dry the film on the nonwoven fabric, and an extrusion unit 5 mounted on the coating machine body 1, the extrusion unit 5 being used to stretch the nonwoven fabric to ensure uniform coating of the plastic film, the extrusion unit 5 including:

[0042] The mounting base 51 is installed on the main body 1 of the coating machine;

[0043] Connecting component 52 is mounted on fixing base 51;

[0044] The connecting frame 53 is located below the fixing base 51. The connecting frame 53 is used to straighten the nonwoven fabric and smooth the edges of the nonwoven fabric to ensure uniform coating of the plastic film and improve the finished product effect of the nonwoven fabric.

[0045] Connection component 52 includes:

[0046] Connecting seat 521 is fixedly connected to the top end face of fixing seat 51;

[0047] The movable seat 522 is fixedly connected to the other end of the push rod 56;

[0048] Spring 523, one end of which is fixedly connected to the top end face of movable seat 522;

[0049] The compression seat 524 is fixedly connected to the other end of the connecting bracket 53.

[0050] When the nonwoven fabric comes into contact with the extrusion roller 55, the extrusion roller 55 moves, causing the push rod 56 to move as well. At this time, the push rod 56 pushes the moving seat 522 to move, compressing the spring 523. Under the rebound of the spring 523, the extrusion roller 55 is pushed to squeeze the nonwoven fabric, tightening the nonwoven fabric and ensuring that the plastic film coating on the nonwoven fabric is uniform.

[0051] An adjusting seat 525 is slidably connected to the inner wall of the connecting seat 521, and the adjusting seat 525 is located above the pressing seat 524.

[0052] When the push rod 56 moves, it drives the moving seat 522, spring 523 and extrusion seat 524 to move. When the extrusion seat 524 contacts the adjusting seat 525, the extrusion seat 524 cannot move. Then, under the movement of the moving seat 522, the spring 523 continues to be compressed. Under the rebound of the spring 523, the extrusion roller 55 is pushed to extrude the nonwoven fabric, tighten the nonwoven fabric and ensure that the plastic film is evenly coated on the nonwoven fabric.

[0053] An adjusting rod 526 is fixedly connected to the top end face of the adjusting seat 525. The adjusting rod 526 is slidably connected to the connecting seat 521, and a thread is provided between the adjusting rod 526 and the connecting seat 521.

[0054] The adjusting rod 526 and the connecting seat 521 are fixed or loosened by bolts. When it is necessary to adjust the compression of the spring 523, the adjusting rod 526 is loosened.

[0055] At this time, the adjusting rod 526 drives the adjusting seat 525 to move along the connecting seat 521, changing the position of the adjusting seat 525. This ensures that when the connecting frame 53 moves to the same position, the moving seat 522 moves the same distance, changing the compression degree of the spring 523. This ensures that the spring 523 does not exert excessive pressure on the pushing rod 56 and the scraper plate 54 under the rebound of the spring 523, thus ensuring that the squeezing roller 55 flattens the nonwoven fabric.

[0056] A support frame 2 is installed below the main body 1 of the coating machine, and inlet / outlet frames 4 are installed on both sides of the main body 1 of the coating machine.

[0057] By placing the film on the feed rack 4, the film is squeezed by the extrusion roller 55 to facilitate stretching, and then the edges of the film are smoothed by the scraper plate 54 to ensure uniform plastic coating on the film.

[0058] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
