Description

Technical Field

[0001] This utility model relates to the field of fabric processing technology, specifically to a fabric rolling mill. Background Technology

[0002] A fabric rolling mill (also known as a fabric roller or fabric rolling machine) is a piece of equipment used in the textile industry to process fabrics. It is used for processes such as smoothing, calendering, setting, and sizing fabrics. The main function of the rolling mill is to convey, compact, smooth, or perform other treatments on the fabric using one or more pairs of rollers. However, existing rolling mills lack corresponding reagent storage equipment. During sample testing, the size of the fabric sample limits the ability to evenly apply reagents to the fabric through a rolling process, and then use roller pressure to control the liquid content. The contact and immersion process between the fabric and reagent cannot be uniform, leading to inconsistent test results and reducing the repeatability and accuracy of the samples. Utility Model Content

[0003] The purpose of this invention is to provide a fabric rolling mill to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a fabric rolling mill, comprising:

[0005] The supporting box is a U-shaped box.

[0006] An upper roller is rotatably positioned in the middle of the support box. A motor for driving the upper roller is installed inside the support box. A lower roller is installed below the upper roller. A hydraulic cylinder for driving the lower roller to rise and fall is installed inside the support box.

[0007] A pressure sensor is placed above the hydraulic cylinder to detect the distance between the lower roll and the upper roll.

[0008] A reagent tank is placed on one side of the support box. A guide roller is rotatably installed inside the reagent tank, and a partition plate is slidably connected to the outside of the guide roller to separate the internal space of the reagent tank.

[0009] Preferably, the side of the support box is provided with a rectangular groove for the end of the lower roller to slide. An L-shaped sealing plate is fixed to the support box at the position corresponding to the rectangular groove. A limit plate is slidably connected inside the sealing plate. The limit plate is rotatably connected to the end of the lower roller.

[0010] Preferably, both ends of the support box are fixedly connected to support frames, the top of the support frame is fixedly connected to a limit rod, the hydraulic cylinder is fixedly connected to the top of the support frame, and the output end of the hydraulic cylinder is fixedly connected to a lifting plate.

[0011] Preferably, the lifting plate is slidably connected to the limiting rod, and the top of the lifting plate is fixedly connected to a bearing seat that is rotatably connected to the lower roller.

[0012] Preferably, the pressure sensor is fixed to the top of the lifting plate, and a fixing rod is fixed to the outside of the limiting rod and above the pressure sensor. A spring rod is fixed to the bottom of the fixing rod, and the end of the spring rod is in contact with the pressure sensor.

[0013] Preferably, a bending roller is fixedly connected to one side of the support box, and a guide plate is fixedly connected to one side of the support box and below the bending roller.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: The lower roller is raised and lowered by a hydraulic cylinder. A relationship is established between the pressure value measured by a pressure sensor and the raising and lowering height. The controller can accurately calculate the distance between the upper and lower rollers, which can be flexibly adjusted according to the fabric thickness to meet the rolling requirements of different fabrics and improve the rolling effect. A sliding partition plate is installed inside the reagent tank, allowing adjustment of the space in the middle of the tank as needed, facilitating small sample testing and improving the applicability of the equipment. A sealing plate and a limiting plate are installed on the side of the support box. When adjusting the height of the lower roller, the limiting plate area is larger than the rectangular groove, and a rubber plate is attached to one side, continuously blocking and sealing the rectangular groove, effectively preventing squeezed liquid from entering the support box and avoiding damage to the equipment. The support frame and limiting rod provide stable support and guidance for the raising and lowering of the lower roller. The hydraulic cylinder raises and lowers the lifting plate outside the limiting rod, and the lifting plate drives the lower roller to rise and fall through the bearing seat, ensuring the smoothness of the lower roller's raising and lowering process and ensuring the smooth operation of the rolling process.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 , 2 As shown in Figures 3, 4, 5, and 6, this utility model provides a technical solution: a fabric rolling mill, comprising: a support box 1, which is a U-shaped box; an upper roller 2 rotatably positioned in the middle of the support box 1, a motor 4 for driving the upper roller 2 fixedly connected inside the support box 1, a lower roller 3 positioned below the upper roller 2, a hydraulic cylinder 12 for driving the lower roller 3 to rise and fall inside the support box 1, and a hydraulic station connected to the hydraulic cylinder 12 on one side of the support box 1; a pressure sensor 10 positioned above the hydraulic cylinder 12 for detecting the distance between the lower roller 3 and the upper roller 2 by measuring the pressure value; a reagent tank 13 fixedly connected to one side of the support box 1, with two guide rollers 14 rotatably installed inside the reagent tank 13, one located on the side and the other located at the lower position inside the reagent tank 13, and a partition plate 15 slidably connected to the outer side of the guide rollers 14 for separating the internal space of the reagent tank 13.

[0024] It should be noted that in this embodiment, a controller and an operation panel are provided. The lower roller 3 is driven to rise and fall by the hydraulic cylinder 12. The controller can calculate the distance between the upper roller 2 and the lower roller 3 by the pressure value of the pressure sensor 10. The fabric is placed between the upper roller 2 and the lower roller 3. The motor 4 drives the upper roller 2 to rotate. Under the action of friction, the lower roller 3 rotates and squeezes the fabric with the upper roller 2. The excess liquid enters the liquid collection tank in the middle of the support box 1 and is discharged through the water pipe at the bottom of the liquid collection tank. When it is necessary to test some small samples, the two partition plates 15 can be slid to a suitable position to adjust the space in the middle of the reagent tank 13 as needed. The reagent is poured between the two partition plates 15. The fabric is wrapped around the outside of the guide roller 14, and then wrapped around the bottom of the guide roller 14 located below and pulled out. It is then placed between the upper roller 2 and the lower roller 3 for testing.

[0025] In one embodiment, a rectangular groove for sliding the end of the lower roller 3 is provided on the side of the support box 1. An L-shaped sealing plate 18 is fixed to the support box 1 at the position corresponding to the rectangular groove. A limiting plate 19 is slidably connected inside the sealing plate 18. The limiting plate 19 is rotatably connected to the end of the lower roller 3.

[0026] It should be noted that, in this embodiment, when the height of the lower roller 3 is adjusted, the end of the lower roller 3 drives the sealing plate 18 to slide inside the limiting plate 19. The area of ​​the limiting plate 19 is larger than the area of ​​the rectangular groove, so that it can always block the rectangular groove when it moves up and down. In addition, a rubber plate is pasted on one side of the limiting plate 19, which can seal the rectangular groove and prevent the squeezed liquid from entering the support box 1.

[0027] In one embodiment, support frames 5 are fixedly connected to both ends of the support box 1, and a limit rod 6 is fixedly connected to the top of the support frame 5. A hydraulic cylinder 12 is fixedly connected to the top of the support frame 5, and a lifting plate 7 is fixedly connected to the output end of the hydraulic cylinder 12. The lifting plate 7 is slidably connected to the limit rod 6, and a bearing seat 8 that is rotatably connected to the lower roller 3 is fixedly connected to the top of the lifting plate 7.

[0028] It should be noted that, in this embodiment, when adjusting the height of the lower roller 3, the hydraulic cylinder 12 lifts and lowers the lifting plate 7 outside the limit rod 6. The lifting plate 7 drives the lower roller 3 to lift and lower within the rectangular groove through the bearing seat 8. This allows the distance between the upper roller 2 and the lower roller 3 to be adjusted according to the thickness of the fabric.

[0029] In one embodiment, the pressure sensor 10 is fixed to the top of the lifting plate 7, and a fixing rod 9 is fixed to the outside of the limiting rod 6 and above the pressure sensor 10. A spring rod 11 is fixed to the bottom of the fixing rod 9. The spring rod 11 is a metal rod that is slidably installed inside a tube, and the end of the metal rod is connected to one end inside the tube by a spring. The end of the spring rod 11 is in contact with the pressure sensor 10.

[0030] It should be noted that, in this embodiment, when the lifting plate 7 moves up and down along the limiting rod 6, the lifting plate 7 causes the pressure sensor 10 to come into contact with the spring rod 11. Since the pressure of the spring rod changes with the height of the lifting plate 7, the pressure value measured by the pressure sensor 10 can establish a certain relationship with the lifting height. When the lifting plate 7 rises, the pressure of the spring rod increases, and the pressure sensor will sense the increase in pressure value. Conversely, when the lifting plate falls, the pressure of the spring rod decreases, and the pressure sensor will sense the decrease in pressure value. Based on the detected pressure values, the controller can calculate the height of the lifting plate 7, because each pressure value corresponds to a specific height.

[0031] In one embodiment, a bending roller 17 is fixedly connected to one side of the support box 1, and a guide plate 16 is fixedly connected to one side of the support box 1 and below the bending roller 17.

[0032] It should be noted that in this embodiment, the extruded fabric is routed around the bottom of the bending roller 17 and connected to a traction or winding device. The bending roller 17 adjusts the tension of the fabric through the lateral tension generated by its curved surface, thereby achieving a smooth or moderately stretched fabric. This can solve the problem of uneven tension causing the fabric to become loose in the middle or wrinkled at the edges during high-speed rolling. The guide plate 16 can receive the liquid generated by the extrusion of the fabric and the bending roller 17.
