Description

Technical Field

[0001] This utility model belongs to the technical field of textile desizing devices, and particularly relates to a textile desizing device. Background Technology

[0002] In the textile fabric processing flow, the desizing device is the core equipment for removing sizing from the fabric. Its function is to remove the sizing material from the surface of the fabric through processes such as soaking and washing inside the chamber, laying the foundation for subsequent dyeing, finishing and other processes. A typical desizing device usually uses enzyme solution and alkali solution prepared inside the chamber, in conjunction with the cleaning device integrated inside the chamber to remove sizing. After the fabric enters the device through the inlet, the sizing material is softened and removed in the desizing treatment area, and then it is output from the outlet.

[0003] The problems with existing technologies are: in textile fabric processing, desizing devices need to complete processes such as fabric soaking, desizing and washing. After desizing, the fabric often has a lot of residual moisture, which cannot be treated in a timely and efficient manner. The residual moisture will increase the energy consumption and time of subsequent drying, affecting production efficiency. In addition, existing devices often have fixed dewatering component structures and insufficient control capabilities, making it difficult to meet the high-efficiency dewatering needs of different fabrics. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides a textile fabric desizing device with the advantages of efficient dehydration, adjustable extrusion pressure, and pre-cleaning of impurities. It improves production efficiency and fabric quality, and to a certain extent improves or solves the problems in textile fabric processing. The desizing device needs to complete processes such as fabric soaking, desizing, and washing. After desizing, the fabric often has a large amount of residual moisture, which cannot be treated in a timely and efficient manner. The residual moisture increases the energy consumption and time of subsequent drying, affecting production efficiency. In addition, existing devices often have fixed dehydration component structures and insufficient control capabilities, making it difficult to meet the efficient dehydration needs of different fabrics.

[0005] This utility model is implemented as follows: a textile fabric desizing device includes a machine body, an inlet, and an outlet. The inlet is located on the upper front side of the machine body, and the outlet is located on the upper rear side of the machine body. A water removal device is provided on the rear side of the outlet. The water removal device includes a housing, a water pressing component, a cleaning component, and an adjusting component. The housing is fixedly connected to the upper rear surface of the machine body. A through groove is provided on the upper rear side of the housing, and the position of the through groove corresponds to the position of the outlet. A return port is provided on the lower front side of the housing at the rear end of the machine body, and the lower end of the housing communicates with the machine body through the return port.

[0006] The preferred water-pressing assembly of this utility model is disposed inside the upper part of the housing. The water-pressing assembly includes positioning rods, a squeezing frame, tension springs, and an upper pressure roller. There are two positioning rods, which are respectively disposed on the left and right sides of the upper part of the housing. The upper ends of the two positioning rods extend out of the housing and are slidably connected to the housing. The squeezing frame is disposed inside the upper part of the housing and is fixedly connected to the lower ends of the two positioning rods. There are two tension springs, which are respectively sleeved on the surfaces of the two positioning rods. The upper and lower ends of the two tension springs are fixedly connected to the upper surface of the housing and the upper surface of the squeezing frame, respectively. The upper pressure roller is disposed at the lower end of the squeezing frame and is rotatably connected to the squeezing frame. By setting up the water-pressing assembly, the squeezing roller can press down on the squeezing frame, thereby driving the upper and lower pressure rollers to squeeze the fabric, squeezing out a large amount of water from the fabric after soaking and desizing. The water then flows out through the return port of the inclined wall at the lower end of the housing and falls into the machine body, thus performing preliminary dehydration of the desizing fabric and preventing the fabric from carrying too much water, which would affect subsequent drying processes.

[0007] As a preferred embodiment of this invention, a lower pressure roller is provided directly below the upper pressure roller. The left and right ends of the lower pressure roller are rotatably connected to the left and right ends inside the housing. By providing a lower pressure roller directly below the upper pressure roller, a squeezing structure is formed with the upper pressure roller to apply a stable clamping force to the fabric, ensuring that the fabric is subjected to uniform force during the squeezing and dehydration process.

[0008] The cleaning component, as a preferred embodiment of this invention, is disposed in front of the pressing component. The cleaning component includes a rubber connecting plate, a rubber scraper, and a stop block. The rubber connecting plate is fixedly connected to the upper front side of the extrusion frame, the rubber scraper is fixedly connected to the lower front side of the rubber connecting plate, and the stop block is disposed directly below the rubber scraper, with its left and right ends fixedly connected to the left and right sides inside the housing. By disposing of the cleaning component in front of the pressing component, the cooperation of the rubber scraper and the stop block can remove the slurry impurities adhering to the fabric surface in advance while scraping water, preventing impurities from entering the pressing area and causing contamination of the roller surface or being further pressed onto the fabric, thus ensuring the continuity and stability of the extrusion and dewatering effect.

[0009] The preferred adjustment component of this invention is disposed above the water-pressing component. The water-pressing component includes a rotating rod, a squeezing wheel, a worm gear, and a driving component. The rotating rod is disposed above the squeezing frame, and its front and rear ends are rotatably connected to the rear end of the machine body and the rear end inside the housing, respectively. The squeezing wheel is disposed directly above the squeezing frame, sleeved on the surface of the rotating rod, and fixedly connected to the rotating rod. The worm gear is sleeved on the rear end surface of the rotating rod and fixedly connected to the rotating rod. The driving component is disposed to the left of the worm gear. By setting the adjustment component above the water-pressing component, the worm gear driven by the motor drives the rotating rod and the squeezing wheel to rotate. The pressure of the squeezing wheel on the squeezing frame can be adjusted in real time according to the fabric material, thickness, and dehydration requirements, so as to achieve precise control of the squeezing pressure between the upper and lower pressure rollers and improve the adaptability and flexibility of the device for fabric desizing and dehydration processes.

[0010] The preferred driving component of this utility model includes a worm gear and a motor. The worm gear is located on the left side of the worm wheel and meshes with it. The upper end of the worm gear extends out of the housing and is rotatably connected to the housing. The motor is fixedly connected to the upper end of the worm gear and to the upper surface of the housing. By setting the driving component, the motor drives the worm gear to rotate. The worm gear meshes with the worm wheel, driving the rotating rod and the extrusion wheel to rotate, thereby precisely adjusting the downward pressure of the extrusion wheel on the extrusion frame. This achieves automated control of the extrusion pressure between the upper and lower pressure rollers. At the same time, the cooperation between the worm gear and the worm wheel has a deceleration effect, providing a stable transmission ratio and avoiding damage to the fabric caused by sudden changes in extrusion pressure, further improving the control accuracy and operational stability of the device.

[0011] As a preferred embodiment of this invention, an electric heating plate is provided above the rear side of the through groove. The electric heating plate is fixedly connected to the rear surface of the housing. By providing an electric heating plate above the rear side of the through groove, the fabric pulled out of the through groove by the rolling device is dried in an auxiliary manner, thereby further reducing the moisture content of the fabric.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, through the coordinated use of a machine body, inlet, outlet, desizing device, shell, water pressing component, positioning rod, extrusion frame, tension spring, upper pressure roller, cleaning component, rubber connecting plate, rubber scraper, stop block, adjusting component, rotating rod, extrusion wheel, worm gear, driving component, worm, motor, through groove, return port, lower pressure roller, and electric heating plate, improves or solves to a certain extent the problems in textile fabric processing where the desizing device needs to complete fabric soaking, desizing, and washing processes. After desizing, the fabric often retains a large amount of water, which cannot be treated in a timely and efficient manner. The residual water increases the energy consumption and time of subsequent drying, affecting production efficiency. In addition, existing devices often have fixed desizing component structures and insufficient control capabilities, making it difficult to meet the efficient desizing needs of different fabrics.

[0020] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0021] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] like Figures 1 to 5 As shown in the figure, the textile desizing device provided in this embodiment of the utility model includes a machine body 1, an inlet 2, and an outlet 3. The inlet 2 is located at the upper front end of the machine body 1, and the outlet 3 is located at the upper rear end of the machine body 1. A water removal device 4 is provided at the rear end of the outlet 3. The water removal device 4 includes a housing 41, a water pressing component 42, a cleaning component 43, and an adjusting component 44. The housing 41 is fixedly connected to the upper rear surface of the machine body 1. A through groove 5 is provided at the upper rear end of the housing 41. The position of the through groove 5 corresponds to the position of the outlet 3. A return port 6 is provided at the rear end of the machine body 1 at the lower front end of the housing 41. The lower end of the housing 41 communicates with the machine body 1 through the return port 6.

[0023] refer to Figure 1 , Figure 2 and Figure 3 The water-pressing assembly 42 is located inside the upper part of the housing 41. The water-pressing assembly 42 includes positioning rods 421, squeezing frames 422, tension springs 423 and upper pressure rollers 424. There are two positioning rods 421, which are respectively located on the left and right sides of the upper part of the housing 41. The upper ends of the two positioning rods 421 extend out of the housing 41 and are slidably connected to the housing 41. The squeezing frames 422 are located inside the upper part of the housing 41 and are fixedly connected to the lower ends of the two positioning rods 421. There are two tension springs 423, which are respectively sleeved on the surface of the two positioning rods 421. The upper and lower ends of the two tension springs 423 are fixedly connected to the upper surface of the housing 41 and the upper surface of the squeezing frames 422, respectively. The upper pressure rollers 424 are located at the lower end of the squeezing frames 422 and are rotatably connected to the squeezing frames 422.

[0024] The above solution is adopted: by setting up the water pressing component 42, the pressing wheel 442 can press down on the pressing frame 422, thereby driving the upper pressing roller 424 and the lower pressing roller 7 to squeeze the fabric, squeezing out a large amount of water from the fabric after soaking and desizing, and then flowing into the machine body 1 from the return port 6 through the inclined wall at the lower end of the housing 41. This achieves the initial dehydration of the desizing fabric and avoids the fabric carrying too much water, which would affect subsequent drying and other processes.

[0025] refer to Figure 2 , Figure 3 and Figure 4 A lower pressure roller 7 is provided directly below the upper pressure roller 424, and the left and right ends of the lower pressure roller 7 are rotatably connected to the left and right ends inside the housing 41.

[0026] The above solution is adopted: by setting a lower pressure roller 7 directly below the upper pressure roller 424, a squeezing structure is formed with the upper pressure roller 424 to apply a stable clamping force to the fabric and ensure that the fabric is subjected to uniform force during the squeezing and dehydration process.

[0027] refer to Figure 2 , Figure 3 and Figure 4 The cleaning and scraping assembly 43 is located in front of the water pressure assembly 42. The cleaning and scraping assembly 43 includes a rubber connecting plate 431, a rubber scraper 432, and a stop block 433. The rubber connecting plate 431 is fixedly connected to the upper front side of the extrusion frame 422. The rubber scraper 432 is fixedly connected to the lower front side of the rubber connecting plate 431. The stop block 433 is located directly below the rubber scraper 432, and its left and right ends are fixedly connected to the left and right sides inside the housing 41.

[0028] The above solution is adopted: by setting a cleaning component 43 in front of the water pressing component 42, the rubber scraper 432 and the abutment block 433 can remove the slurry impurities attached to the fabric surface in advance while scraping water, so as to avoid impurities entering the water pressing area and causing roller surface contamination or being further pressed onto the fabric, thus ensuring the continuity and stability of the squeezing and dewatering effect.

[0029] refer to Figure 2 , Figure 3 and Figure 4 The adjusting component 44 is located above the water-pressing component 42. The water-pressing component 42 includes a rotating rod 441, a squeezing wheel 442, a worm gear 443, and a driving component 444. The rotating rod 441 is located above the squeezing frame 422, and its front and rear ends are rotatably connected to the rear end of the chassis body 1 and the rear end inside the shell 41, respectively. The squeezing wheel 442 is located directly above the squeezing frame 422, and is sleeved on the surface of the rotating rod 441 and fixedly connected to the rotating rod 441. The worm gear 443 is sleeved on the rear end surface of the rotating rod 441 and fixedly connected to the rotating rod 441. The driving component 444 is located to the left of the worm gear 443.

[0030] The above solution is adopted: by setting an adjustment component 44 above the water pressing component 42, the motor 4442 drives the worm gear 4441 and worm wheel 443 to drive the rotating rod 441 and the extrusion wheel 442 to rotate. The degree of pressure of the extrusion wheel 442 on the extrusion frame 422 can be adjusted in real time according to the fabric material, thickness and dewatering requirements, so as to achieve precise control of the extrusion pressure between the upper pressure roller 424 and the lower pressure roller 7, and improve the adaptability and flexibility of the device to the fabric desizing and dewatering process.

[0031] refer to Figure 2 , Figure 3 and Figure 4 The drive component 444 includes a worm gear 4441 and a motor 4442. The worm gear 4441 is located on the left side of the worm wheel 443 and is meshed with the worm gear 4441. The upper end of the worm gear 4441 extends out of the housing 41 and is rotatably connected to the housing 41. The motor 4442 is fixedly connected to the upper end of the worm gear 4441 and is fixedly connected to the upper surface of the housing 41.

[0032] The above solution involves setting up a drive component 444, which uses a motor 4442 to drive the worm gear 4441 to rotate. The worm gear 4441 meshes with the worm wheel 443, driving the rotating rod 441 and the extrusion wheel 442 to rotate. This allows for precise adjustment of the pressure exerted by the extrusion wheel 442 on the extrusion frame 422, achieving automated control of the extrusion pressure between the upper pressure roller 424 and the lower pressure roller 7. Simultaneously, the cooperation between the worm gear 4441 and the worm wheel 443 has a speed reduction effect, providing a stable transmission ratio and preventing sudden changes in extrusion pressure from damaging the fabric. This further improves the control accuracy and operational stability of the device.

[0033] refer to Figure 2 , Figure 3 and Figure 5 A heating plate 8 is provided above the rear side of the through groove 5, and the heating plate 8 is fixedly connected to the rear surface of the housing 41.

[0034] The above solution involves installing an electric heating plate 8 above the rear side of the through groove 5 to assist in drying the fabric pulled out of the through groove 5 by the winding equipment, thereby further reducing the moisture content of the fabric.

[0035] The working principle of this utility model:

[0036] In operation, the textile fabric enters through inlet 2 at the upper front of the machine body 1. After desizing inside the machine body 1, it enters the housing 41 of the dewatering device 4 through outlet 3. It then exits through the through-slot 5 at the rear of the housing 41 and connects to the winding equipment. The motor 4442 drives the worm gear 4441 to rotate. The worm gear 4441 meshes with the worm wheel 443, driving the rotating rod 441 and the extrusion wheel 442 to rotate. The extrusion wheel 442 rotates, and its protrusions press downwards against the extrusion frame 422, causing the inner wall of the extrusion frame 422 to move downwards. Simultaneously, the downward movement of the extrusion frame 422 drives the positioning rod 421 to move into the housing 41, thus limiting and stabilizing the movement trajectory of the extrusion frame 422. At the same time, it stretches the tension spring 423. The downward movement of the extrusion frame 422 drives the upper pressure roller 424, in conjunction with the lower pressure roller 7, to press water onto the fabric being wound. The upper pressure roller 424 and the lower pressure roller 7 also assist in this process. The rotation adjusts the pressure between the upper pressure roller 424 and the lower pressure roller 7 by pressing the pressure roller 442 on the pressure frame 422. At the same time, the rubber connecting plate 431 drives the rubber scraper 432 to move synchronously with the pressure frame 422. The rubber scraper 432 and the abutment block 433 fixed inside the housing 41 form a clamping gap. Through the friction of the fabric movement, the slurry, fiber impurities and other impurities attached to the surface are scraped off, preventing impurities from entering the pressing area of ​​the upper pressure roller 424 and the lower pressure roller 7, preventing roller surface contamination or impurities embedded in the fabric and affecting the subsequent processing quality. A large amount of water in the fabric is squeezed out. The water is guided through the inclined wall at the lower end of the housing 41 and returned to the machine body 1 through the return port 6 for recycling. The dehydrated fabric is led out from the through groove 5 on the rear side of the housing 41. The electric heating plate 8 above the rear end of the through groove 5 is energized and heated to dry the surface of the fabric passing through, further reducing the moisture content, thereby removing water.

[0037] When the cleaning and scraping assembly 43 and the water pressing assembly 42 are adjusted upwards, the control motor 4442 drives the worm gear 4441 to rotate in the opposite direction. The worm gear 4441 drives the worm wheel 443 and the rotating rod 441 to rotate in the opposite direction. The rotating protrusion of the extrusion roller 442 gradually moves away from the extrusion frame 422. The elastic restoring force of the tension spring 423 pushes the extrusion frame 422 to move upwards along the positioning rod 421, which increases the distance between the upper pressure roller 424 and the lower pressure roller 7 and reduces the extrusion pressure. At the same time, the rubber scraper 432 moves upwards with the extrusion frame 422, and the clamping gap between it and the abutment block 433 expands, reducing the frictional resistance to the fabric. This makes it easier to release the fabric tension when changing fabric types or stopping the machine for maintenance, and avoids excessive extrusion that could damage the fabric.

[0038] In summary, this textile fabric desizing device, through the coordinated use of a machine body 1, inlet 2, outlet 3, dewatering device 4, shell 41, water pressing component 42, positioning rod 421, extrusion frame 422, tension spring 423, upper pressure roller 424, cleaning component 43, rubber connecting plate 431, rubber scraper 432, abutment block 433, adjusting component 44, rotating rod 441, extrusion wheel 442, worm gear 443, driving component 444, worm 4441, motor 4442, through groove 5, return port 6, lower pressure roller 7, and heating plate 8, improves or solves to a certain extent the problems encountered in textile fabric processing. Desizing devices need to complete processes such as fabric soaking, desizing, and washing. After desizing, the fabric often retains a large amount of moisture, which cannot be treated in a timely and efficient manner. This residual moisture increases subsequent drying energy consumption and time, affecting production efficiency. Furthermore, existing devices often suffer from fixed dewatering component structures and insufficient control capabilities, making it difficult to meet the efficient dewatering needs of different fabrics.

[0039] It should be noted that the motor 4442 is a device or equipment existing in the prior art, or a device or equipment that can be implemented by the prior art, and the specific composition and principle of the power supply of the motor 4442 are clear to those skilled in the art, so they will not be described in detail.
