Description

Technical Field

[0001] This utility model relates to the field of textile fabric processing technology, specifically to a textile fabric desizing and alkali-adding device. Background Technology

[0002] During the weaving process, the warp yarns are subjected to significant tension and friction, making them prone to breakage. Therefore, to reduce warp breakage and improve weaving efficiency and fabric quality, the warp yarns need to be sized before weaving to enhance their breaking strength and abrasion resistance. Sizing agents can affect the wettability of the fabric during dyeing and finishing and hinder the contact of chemicals with the fibers. Although sizing is beneficial for weaving, it creates difficulties for subsequent dyeing and finishing processes and affects the printing and dyeing effect. Therefore, the fabric needs to be desized. Desizing refers to treating the fabric with acids, alkalis, enzymes, etc., to remove the sizing agents added to the warp yarns during weaving. This process facilitates subsequent processing such as scouring.

[0003] Existing desizing technologies often involve immersing the fabric in a desizing solution. During static immersion, the agent can only penetrate into the fiber through molecular diffusion. The rate is limited by the thickness of the sizing layer and the fluidity of the liquid. A nearly static liquid film will form on the fabric surface, which will hinder the contact between fresh liquid and the fiber, resulting in low desizing efficiency and unsatisfactory results, which cannot meet production standards.

[0004] Therefore, it is of great importance to design a desizing and alkali-adding device for textile fabrics to solve the above-mentioned defects. Utility Model Content

This device aims to solve the technical problem that the existing static soaking desizing method for textile fabrics has low desizing efficiency and unsatisfactory results, failing to meet production standards.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A textile fabric desizing and alkali-adding device includes a housing, with guide rollers rotatably connected to both the front and rear ends of the housing, two sets of conveying rollers rotatably connected to the bottom of the housing, a vibration assembly fixedly installed at the top of the housing and between the two sets of conveying rollers, an alkali-adding box fixedly installed at the top of the housing and in front of the vibration assembly, an extrusion mechanism fixedly installed at the rear end of the housing and below the guide rollers, and a filter box fixedly installed inside the housing and below the extrusion mechanism.

[0008] The vibration assembly includes a protective box fixedly installed on the top of the housing. An installation plate is fixedly installed inside the protective box. A turntable is rotatably connected to the front end of the installation plate. A first motor is fixedly installed on the left side of the protective box. A lifting rod is slidably connected to the rear end of the installation plate. A swing frame is rotatably connected between the turntable and the lifting rod. A sliding column is fixedly connected to the surface of the turntable. The sliding column is slidably connected to the front end of the swing frame through a guide groove. Multiple sets of toothed grooves are opened at the rear end of the swing frame. Multiple sets of toothed blocks mesh with the toothed grooves on the outer side of the lifting rod. A vibration roller is rotatably connected to the bottom end of the lifting rod.

[0009] As a preferred embodiment of this utility model, a box cover is fixedly installed on the right side of the protective box, the outer side of the lifting rod is slidably connected to the upper and lower ends of the protective box, the outer side of the lifting rod is slidably connected to the upper and lower ends of the mounting plate through a sliding sleeve, and the outer side of the lifting rod is slidably connected to the inside of the box body through a guide sleeve.

[0010] As a preferred embodiment of this utility model, a power box is fixedly installed on the right side of the box body, and a second motor is fixedly installed at the front end of the power box. The drive end of the second motor is connected to the right end of the two sets of conveying rollers through a synchronous pulley set.

[0011] As a preferred embodiment of this utility model, the top of the alkali addition box is threaded with a cover, a pump is fixedly installed on the front of the alkali addition box, the input end of the pump is connected to the bottom of the inside of the alkali addition box, a delivery pipe is fixedly installed on the output end of the pump, and the delivery pipe extends to the bottom of the inside of the box, and a drain pipe is fixedly installed at the bottom of the front of the box.

[0012] As a preferred embodiment of this utility model, the extrusion mechanism includes two sets of fixed frames fixedly installed inside the rear end of the box and located below the guide roller. Each set of fixed frames is slidably connected to a movable frame on the opposite side. Each set of movable frames is fixedly connected to a set of fixed frames and a set of springs. Each set of movable frames is rotatably connected to an extrusion roller on the opposite side.

[0013] As a preferred embodiment of this utility model, both ends of the two sets of movable frames are fixedly connected with stabilizing columns, and the stabilizing columns are slidably connected to the fixed frames through sliding grooves.

[0014] As a preferred embodiment of this utility model, a cleaning frame is slidably connected inside the filter box, a filter screen is fixedly installed at the bottom inside the cleaning frame, and a handle is fixedly installed on the right side of the cleaning frame.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

The vibrating roller at the bottom of the lifting rod vibrates with the lifting rod, patting and loosening the sizing material on the fabric. Through the vibration, the penetration efficiency of the desizing liquid is effectively improved, making it easier for the sizing material to fall off the fabric. The vibration also promotes the uniformity of mixing between the fabric and the desizing liquid, thereby improving the desizing efficiency and effect.

[0017] 2. In this utility model, through the coordinated design of the extrusion mechanism and the filter box, when the desized fabric passes through the extrusion mechanism, two sets of extrusion rollers squeeze the fabric. The extrusion rollers are connected by springs between the movable frame and the fixed frame, and have a certain elasticity. The movable frame moves stably under the cooperation of the stabilizing column and the sliding groove. During the extrusion process, the elasticity of the spring makes the extrusion rollers adapt to the changes in fabric thickness, ensuring the extrusion effect, thereby effectively removing excess desizing liquid and sizing residue from the fabric, improving the cleanliness of the fabric. The waste liquid discharged by the extrusion mechanism contains detached sizing liquid, fiber debris and chemical residues. The waste liquid flows into the filter box by gravity and is filtered through the filter screen in the cleaning frame. The cleaning frame can be slidably pulled out, which is convenient for cleaning and replacing the filter screen, realizing continuous purification and recycling of desizing liquid, and further reducing production costs.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] Example: Please refer to Figures 1-5 This utility model provides a technical solution:

[0026] A textile fabric desizing and alkali-adding device includes a housing 1. Guide rollers 2 are rotatably connected to both the front and rear ends of the housing 1. Two sets of conveying rollers 3 are rotatably connected to the bottom of the housing 1. A vibration component 4 is fixedly installed on the top of the housing 1 between the two sets of conveying rollers 3. An alkali-adding box 5 is fixedly installed on the top of the housing 1 in front of the vibration component 4. An extrusion mechanism 6 is fixedly installed at the rear end of the housing 1 below the guide rollers 2. A filter box 7 is fixedly installed inside the housing 1 below the extrusion mechanism 6.

[0027] First, in this embodiment, the specific structure of the vibration component 4 is as follows:

[0028] The vibration assembly 4 includes a protective box 401 fixedly installed on the top of the housing 1. An installation plate 402 is fixedly installed inside the protective box 401. A turntable 403 is rotatably connected to the front end of the installation plate 402. A first motor 404 is fixedly installed on the left side of the protective box 401. A lifting rod 405 is slidably connected to the rear end of the installation plate 402. A swing frame 406 is rotatably connected between the turntable 403 and the lifting rod 405. A sliding column 407 is fixedly connected to the surface of the turntable 403. The sliding column 407 is slidably connected to the front end of the swing frame 406 via a guide groove 408. Multiple sets of toothed grooves 409 are provided at the rear end of the swing frame 406. The outer side of the lifting rod 405 engages with the toothed grooves 409 via multiple sets of toothed blocks 410, thus raising and lowering the rod. A vibrating roller 411 is rotatably connected to the bottom end of the rod 405. During the desizing process, the first motor 404 is started to drive the turntable 403 to rotate. The sliding column 407 on the surface of the turntable 403 slides in the guide groove 408, pushing the swing frame 406 to swing. The toothed groove 409 at the rear end of the swing frame 406 meshes with the toothed block 410 on the outer side of the lifting rod 405, causing the lifting rod 405 to move up and down. The vibrating roller 411 at the bottom end of the lifting rod 405 vibrates with the lifting rod 405, beating and loosening the sizing material on the fabric. Through the vibration, the penetration efficiency of the desizing liquid is effectively improved, making it easier for the sizing material to fall off the fabric. The vibration also promotes the uniformity of mixing between the fabric and the desizing liquid, thereby improving the desizing efficiency and effect.

[0029] Furthermore, a cover 412 is fixedly installed on the right side of the protective box 401. The outer side of the lifting rod 405 is slidably connected to the upper and lower ends of the protective box 401. The outer side of the lifting rod 405 is slidably connected to the upper and lower ends of the mounting plate 402 through a sliding sleeve 413. The outer side of the lifting rod 405 is slidably connected to the inside of the box 1 through a guide sleeve 414. The cover 412 can be opened for maintenance and repair of the inside of the protective box 401. The sliding connection between the lifting rod 405 and the protective box 401 ensures the stable lifting and lowering of the lifting rod 405 in the vertical direction, avoiding deviation or shaking, thereby ensuring the uniform vibration effect of the vibrating roller 411 on the fabric. The sliding sleeve 413 provides additional support and guidance for the lifting rod 405, reducing friction and resistance during the lifting process, while ensuring the relative position stability between the lifting rod 405 and the mounting plate 402. The guide sleeve 414 further strengthens the guiding role of the lifting rod 405, ensuring that it maintains the correct alignment with the inside of the box 1 throughout the lifting process, thus ensuring the stable operation of the vibration assembly 4.

[0030] Then, a power box 301 is fixedly installed on the right side of the box 1. A second motor 302 is fixedly installed at the front end of the power box 301. The drive end of the second motor 302 is connected to the right end of the two sets of conveying rollers 3 through a synchronous pulley set 303. When the second motor 302 is started, it drives the two sets of conveying rollers 3 to rotate through the synchronous pulley set 303. The conveying rollers 3 convey the textile fabric to achieve continuous desizing treatment.

[0031] Furthermore, the top of the alkali addition box 5 is threaded with a cover 501, and a pump 502 is fixedly installed on the front of the alkali addition box 5. The input end of the pump 502 is connected to the bottom of the inside of the alkali addition box 5, and a delivery pipe 503 is fixedly installed on the output end of the pump 502, extending to the bottom of the inside of the box 1. A drain pipe 504 is fixedly installed at the bottom of the front of the box 1. The alkali addition box 5 contains alkali solution. The pump 502 draws the alkali solution from the bottom of the alkali addition box 5, and the alkali solution is delivered to the bottom of the inside of the box 1 through the delivery pipe 503 to replenish the alkali solution inside the box 1. The waste liquid inside the box 1 is discharged through the drain pipe 504.

[0032] Secondly, the extrusion mechanism 6 includes two sets of fixed frames 601 fixedly installed inside the rear end of the housing 1 and located below the guide roller 2. Movable frames 602 are slidably connected to opposite sides of the two sets of fixed frames 601. Multiple sets of springs 603 are fixedly connected between the two sets of movable frames 602 and the fixed frames 601. Extrusion rollers 604 are rotatably connected to opposite sides of the two sets of movable frames 602. Stabilizing columns 605 are fixedly connected to both ends of the two sets of movable frames 602. The stabilizing columns 605 are slidably connected to the fixed frames 601 via sliding grooves 606. When the desizing treated fabric passes through the extrusion mechanism 6, two sets of extrusion rollers 604 extrude the fabric. The extrusion rollers 604 are connected by springs 603 between the movable frame 602 and the fixed frame 601, and have a certain degree of elasticity. The movable frame 602 moves stably with the cooperation of the stabilizing column 605 and the slide 606. During the extrusion process, the elasticity of the spring 603 makes the extrusion rollers 604 adapt to the changes in fabric thickness, ensuring the extrusion effect, thereby effectively removing excess desizing liquid and sizing residue from the fabric and improving the cleanliness of the fabric.

[0033] Finally, a cleaning frame 701 is slidably connected inside the filter box 7. A filter screen 702 is fixedly installed at the bottom of the cleaning frame 701. A handle 703 is fixedly installed on the right side of the cleaning frame 701. The waste liquid discharged by the extrusion mechanism 6 contains sludge, fiber debris and chemical residues. The waste liquid flows into the filter box 7 by gravity and is filtered through the filter screen 702 inside the cleaning frame 701. The cleaning frame 701 can be slidably pulled out to facilitate cleaning and replacement of the filter screen 702. This realizes continuous purification and recycling of the desizing liquid and further reduces production costs.

[0034] In this embodiment, the specific implementation scenario is as follows: the textile fabric is introduced into the box 1 by the guide roller 2. The second motor 302 is started to drive the two sets of conveyor rollers 3 to rotate through the synchronous belt pulley group 303. The conveyor rollers 3 convey the textile fabric to achieve continuous desizing. During the desizing process, the first motor 404 is started to drive the turntable 403 to rotate. The sliding column 407 on the surface of the turntable 403 slides in the guide groove 408, pushing the swing frame 406 to swing. The toothed groove 409 at the rear end of the swing frame 406 meshes with the toothed block 410 on the outer side of the lifting rod 405. The lifting rod 405 moves up and down, and the vibrating roller 411 at the bottom of the lifting rod 405 vibrates with the movement of the lifting rod 405, beating and loosening the sizing agent on the fabric. Through vibration, the penetration efficiency of the desizing solution is effectively improved, making it easier for the sizing agent to fall off the fabric. Vibration also promotes the uniformity of mixing between the fabric and the desizing solution, thereby improving the desizing efficiency and effect. The alkali addition box 5 contains alkali solution, and the pump 502 draws the alkali solution from the bottom of the alkali addition box 5. The alkali solution is transported through the delivery pipe 503 to the bottom of the box 1 to replenish the box. 1. The internal alkaline solution, after desizing, causes the fabric to pass through the extrusion mechanism 6. Two sets of extrusion rollers 604 squeeze the fabric. The extrusion rollers 604 are connected to the fixed frame 601 by springs 603, giving them a certain degree of elasticity. The movable frame 602 moves stably with the cooperation of the stabilizing column 605 and the slide 606. During the extrusion process, the elasticity of the springs 603 allows the extrusion rollers 604 to adapt to changes in fabric thickness, ensuring the extrusion effect. This effectively removes excess desizing solution and sizing residue from the fabric, improving the fabric's... The waste liquid discharged by the extrusion mechanism 6 contains sludge, fiber debris and chemical residues. The waste liquid flows into the filter box 7 by gravity and is filtered by the filter screen 702 in the cleaning frame 701. The cleaning frame 701 can be slidably pulled out to facilitate cleaning and replacement of the filter screen 702. This realizes the continuous purification and recycling of the desizing liquid. The whole operation process is simple and convenient. This utility model improves the desizing efficiency and effect and reduces the production cost through the synergistic design of vibration desizing, elastic extrusion and modular filtration.
