Description

Technical Field

[0001] The invention relates to the technical field of fabric sizing, in particular to a double-layer sizing machine, and also to a sizing method using the double-layer sizing machine. Background Art

[0002] The sizing machine is a device used at the inlet of the high-temperature stenter setting machine to automatically apply sizing material to the fabric surface. However, there are still many problems with the sizing machines currently used in the market: First, currently, the sizing machines on the market are all single-layer sizing machines, that is, they can only size the front or back of the fabric separately, and there is no double-layer sizing machine. If some fabrics need to be double-sided sizing, at least two single-sided sizing machines are needed to meet the requirements. This requires that the site must be larger to accommodate two sizing machines at the same time, and the sizing process from single side to double side takes a relatively long time, which may easily cause different sizing levels on both sides, thus affecting the fabric effect; Second, as one of the important parts of the sizing machine, the sizing roller surface must have a certain degree of roughness to allow the fabric to be sizing, and must also be as smooth as possible to prevent damage to the fabric surface. The existing sizing roller surface is mostly made of round steel, resulting in insufficient sizing on the roller surface. The equipment needs to reduce the running speed to extend the fabric sizing time, thereby reducing production efficiency; Third, most of the angle rollers for fabric sizing are currently non-adjustable, or are only manually adjusted by changing the installation position, which is inconvenient to operate and affects the fabric sizing effect.

DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] Reference Figure 1-6 A double-layer sizing machine includes a wall panel 1 used as a basic supporting structure. In order to increase the reliability of the wall panel 1, support members 2 are installed at the four corners of the wall panel 1. A sizing mechanism I for sizing one side of the fabric is installed on the upper part of the wall panel 1, and a sizing mechanism II for sizing the other side of the fabric is installed on the lower part of the wall panel 1. This upper and lower layered design not only saves space, but also realizes continuous and efficient sizing of both sides of the fabric.

[0019] One side of the sizing mechanism I and the sizing mechanism II are both set as the cloth feeding side, and the other side of the sizing mechanism I and the sizing mechanism II are both set as the cloth discharging side. The sizing mechanism I and the sizing mechanism II both include a spreading roller 9, a sizing roller 7 and a cloth guide roller 3 which are arranged in sequence from the cloth feeding side to the cloth discharging side. The spreading roller 9 is a key pretreatment component before the fabric is sizing, and is used to smoothly spread the fabric and send it into the sizing area to ensure the flatness and uniformity of the fabric sizing. Preferably, the support shaft of the spreading roller 9 is installed on the wall panel 1 through a bearing and a bearing seat 91, and a spreading motor 92 is also installed on the wall panel 1, and the motor shaft of the spreading motor 92 is connected to the support shaft of the spreading roller 9 by transmission. Specifically, the spreading motor 92 is installed through a mounting seat 93, and a driving pulley 94 is installed on the motor shaft of the spreading motor 92, and a transmission pulley 95 is installed on the support shaft of the spreading roller 9, and the driving pulley 94 and the transmission pulley 95 are driven by a transmission belt.

[0020] The sizing roller 7 is used to directly contact the fabric, so that the slurry is evenly transported to the fabric. In order to improve the sizing amount and uniformity of the slurry, a mesh knurling 71 for increasing the sizing amount of the slurry is provided on the roller surface of the sizing roller 7. The mesh knurling 71 for increasing the sizing amount of the slurry is provided on the roller surface of the sizing roller 7, which not only increases the contact area between the slurry and the fabric, but also can effectively prevent the slurry from accumulating or sliding on the roller surface, thereby further improving the sizing effect. Preferably, the mesh knurling 71m=0.3, and the mesh angle is 60°; The cloth guide roller 3 is used to guide the sizing-treated fabric outwards to ensure that the fabric can enter the next process smoothly and orderly.

[0021] In order to cooperate with the sizing operation of the sizing roller 7, a material trough is installed on the wallboard 1 directly below the sizing roller 7, which is used to hold the sizing material and provide a future for the sizing roller 7. A scraper assembly 6 for cooperating with the sizing roller 7 is installed on the material trough to scrape off excess sizing material and facilitate the adjustment of the thickness of the sizing material. A cloth pressing roller for cooperating with the sizing roller 7 is installed on the wall panel 1 directly above the sizing roller 7, and is used to press the fabric during sizing to ensure stability and uniformity during the sizing process. Preferably, the cloth pressing roller is installed on the wall panel 1 through a cloth pressing driving cylinder 5, so that the height of the cloth pressing roller can be adjusted through the cloth pressing driving cylinder 5 as needed, and the pressure of the cloth pressing roller on the fabric can be flexibly controlled; Pneumatic angle adjustment devices for cooperating with the fabric are installed on the wall panels 1 on both sides of the cloth pressing roller, which are used to adjust the height of the fabric when the fabric enters and exits the sizing roller 7 to adjust the fabric angle, which helps to enhance the sizing effect. Preferably, the pneumatic angle adjustment device includes an angle adjustment roller 4 and a fine-adjustable stroke cylinder 41 for driving the angle adjustment roller 4 to move up and down. The fine-adjustable stroke cylinder 41 can flexibly control the up and down movement of the angle adjustment roller 4, thereby improving the stability and position accuracy of the fabric during the sizing process; at the same time, after the fine-adjustable stroke cylinder 41 reaches the theoretical maximum stroke, the cylinder stroke can still be fine-tuned to better meet actual usage needs.

[0022] The cloth inlet side and cloth outlet side of sizing mechanism I and sizing mechanism II are oppositely arranged, that is, the cloth inlet side of sizing mechanism II and the cloth outlet side of sizing mechanism I are arranged on the same side, and the cloth outlet of sizing mechanism II and the cloth inlet side of sizing mechanism I are arranged on the same side, so that after the fabric is sizing by sizing mechanism I, it can be directly turned over and sent to sizing mechanism II for sizing on the other side, which greatly simplifies the operation process, reduces the loss of fabric in the transmission process, and improves the overall production efficiency.

[0023] In order to better lead out the fabric, a number of guide rollers 12 are installed on the wall panel 1 below the sizing mechanism II for leading the sizing fabric out of the fabric inlet side of the sizing mechanism II. When the fabric is led out from the fabric inlet side of the sizing mechanism II, necessary guidance and support are provided to ensure that the fabric can enter the next process smoothly and orderly.

[0024] During actual use, an inclined slurry receiving plate 10 is installed on the wall panel 1 just below the spreading roller 9 of the sizing mechanism II, and slurry receiving trays 11 are installed on both sides of the slurry receiving plate 10, so that the dripping slurry can be collected in time and led to the slurry receiving tray 11, keeping the equipment clean and hygienic. Secondly, the setting of the slurry receiving tray 11 ensures that the fabric will not be affected by the upper slurry and damage the fabric surface after being sizing by the lower layer.

[0025] A double-layer sizing method, the steps are as follows: (1) The fabric is fed into the sizing mechanism I from the fabric feeding side, and the fabric is first flattened by the spreading roller; (2) The flattened fabric passes through the sizing roller, which evenly applies sizing to one side of the fabric. At the same time, the pressing roller presses the fabric to allow the sizing liquid to penetrate into the fabric. (3) The fabric that has been sizing on one side is sent out from the fabric outlet side of sizing mechanism I, and then sent into sizing mechanism II through the fabric inlet side of sizing mechanism II; (4) The fabric fed into the sizing mechanism II is flattened and turned over by the spreading roller so that the other side faces the sizing roller; (5) The sizing roller evenly applies sizing to the other side of the fabric. At the same time, the pressing roller presses the fabric to allow the sizing liquid to penetrate into the fabric. (6) The fabric that has been starched on both sides is sent out from the fabric outlet side of the sizing mechanism II.

[0026] When the sizing rollers of sizing mechanism I and sizing mechanism II are sizing the fabric, the height of the fabric entering and exiting the sizing rollers is finely adjusted by the pneumatic wrap angle adjustment devices on both sides of the sizing rollers to adjust the fabric wrap angle (that is, to adjust the size of the contact surface between the fabric and the sizing roller).

[0027] The double-layer sizing machine achieves continuous and efficient sizing treatment on both sides of the fabric through clever layout and sophisticated design. At the same time, it also has the advantages of high stability, easy operation and convenient maintenance, and can provide strong support for textile production.
