Description

Technical Field

[0001] This utility model relates to the field of sizing device technology, specifically a new type of sizing device for textile machines. Background Technology

[0002] In the textile industry, sizing is a key process that affects fabric quality. Traditional sizing equipment generally suffers from defects such as uneven sizing distribution, insufficient penetration, and sizing waste. If the material is not fully soaked and coated by the sizing during the sizing process, problems such as insufficient yarn strength and low abrasion resistance are likely to occur in subsequent textile processes, and even yarn breakage may occur, causing the loom to stop.

[0003] To address the aforementioned problems of uneven sizing distribution, insufficient permeability, and sizing sedimentation and deterioration, Chinese Patent Publication No. CN222666273U discloses a sizing device for textile machines, belonging to the technical field of sizing devices. The device includes a sizing tank, a sizing box fixedly connected to the bottom of the sizing tank, a funnel fixedly connected to the bottom of the sizing box, and an opening at the bottom of the sizing box. A support plate is fixedly connected to the surface of the funnel, and two sizing components are arranged inside the sizing box. Each sizing component includes a hollow roller arranged opposite to each other, with multiple spray holes on the surface of the hollow roller. One end of the hollow roller is rotatably connected to the side wall of the sizing box via a rotating shaft that passes through the side wall. This prior art, by incorporating a hollow roller, a sizing tank, a funnel, and a circulating pump, allows the sizing material in the sizing tank to enter a connecting pipe through an outlet pipe, then through a U-shaped pipe into the inside of the hollow roller, and finally sprayed out through the spray holes, thus achieving the sizing function of the yarn and ensuring uniform sizing while fully utilizing the sizing material.

[0004] In the above scheme, the slurry is circulated within the device through hollow rollers, slurry tank, funnel and circulating pump to prevent slurry sedimentation and deterioration. The slurry is then squeezed between the hollow rollers to make the distribution of the slurry on the material more uniform. Since the yarn is made of natural fibers or various chemical short fibers before sizing, the air holes on it during sizing can easily lead to uneven sizing of the yarn. Therefore, we propose a new type of textile machine sizing device. Utility Model Content

[0005] To address the aforementioned technical problems, this application provides a novel textile sizing device, comprising a sizing housing, a base mounted at the bottom of the sizing housing, extrusion rollers symmetrically mounted inside the sizing housing, a stirring motor mounted at the top of the sizing housing, a delivery pump mounted on one side of the sizing housing, and a delivery pipe connecting the bottom of the sizing housing and the delivery pump. The stirring motor is equipped with a stirring rod, and a spraying mechanism is installed inside the sizing housing. The spraying mechanism is located above the extrusion rollers, and one side of the spraying mechanism is connected to the output end of the delivery pump via the delivery pipe. The spraying mechanism includes symmetrically arranged rotating rollers, mounting plates and delivery plates respectively mounted at both ends of the two rotating rollers.

[0006] In some embodiments, the rotating roller includes a rotating outer shell, a fixed rod disposed inside the rotating outer shell, mating rings installed at both ends of the rotating outer shell, and an external toothed ring sleeved on the rotating outer shell. A connecting block is provided at the connection between the mounting plate and the conveying plate and the rotating roller. The connecting block engages with the mating ring for rotation. A bidirectional thrust ball bearing is provided between the mating ring and the connecting block.

[0007] In some embodiments, the rotating housing has a plurality of inclined incision holes, which are linearly and equally spaced on the rotating housing, and the inclined incision holes face the direction of the extrusion roller.

[0008] In some embodiments, the two ends of the fixing rod are respectively mounted on the conveying plate and the mounting plate, and a plurality of scrapers are mounted on the fixing rod, with the plurality of scrapers corresponding to a plurality of incised holes in the slope.

[0009] In some embodiments, the rotating housing is elliptical, the ramp inner hole is located on the outer surface of the elliptical minor diameter of the rotating housing, and the scraper engages with the ramp inner hole.

[0010] In some embodiments, a drive gear is further provided on the connecting block of the mounting plate. The drive gear is driven by a built-in motor mounted on the connecting block, and the drive gear meshes with an external gear ring to rotate.

[0011] In some embodiments, a rotating shaft is mounted on the mounting plate, the rotating shaft is driven to rotate by an external power source, the rotating shaft is rotatably connected to the sizing housing, a connecting joint is provided on the conveying plate, the connecting joint is nested and rotated with the conveying pipe on the conveying pump, and the connecting joint is rotatably connected to the sizing housing.

[0012] This utility model has at least the following beneficial effects:

[0013] This invention features a series of inclined inner-cut holes on the rotating outer shell of the spraying mechanism. The angle and spacing between the two rotating rollers driven by the rotating shaft, along with the pressure provided by the delivery pump, allow the slurry to spray onto the yarn surface. This results in a secondary sizing process on the yarn before it enters the extrusion rollers. The reciprocating rotation of the rollers further enhances the slurry's ability to fill the tiny pores between the yarn fibers, solving the problem of uneven slurry adhesion caused by yarn pore tension in traditional devices. A fixed scraper, working in conjunction with the inclined inner-cut holes on the reciprocating rotating outer shell, cleans the sediment generated within these holes, ensuring stable operation of the spraying mechanism and improving the uniformity of slurry distribution.

[0014] This invention, by setting up a delivery pump to drive the internal circulation of the slurry, combined with the angle adjustment function of the spraying mechanism's rotating shaft, can better prevent slurry sedimentation within the device. The rotational movement of the rotating rollers around the shaft can break down any waxy crystals that may form in the slurry. The spraying mechanism can adjust the spacing between the rotating rollers and the spraying angle according to the yarn type or process requirements, thereby controlling the amount of slurry sprayed per unit area, ensuring sizing quality, reducing the frequency of equipment downtime and maintenance due to sedimentation, and improving the production efficiency of the device.

Detailed Implementation

[0021] 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. Example

[0022] Please see Figure 1-5 This utility model provides a technical solution: a novel textile sizing device, including a sizing shell 4, a base 5 installed at the bottom of the sizing shell 4, extrusion rollers 3 symmetrically installed inside the sizing shell 4, a stirring motor 1 installed at the top of the sizing shell 4, a conveying pump 7 installed on one side of the sizing shell 4, and a conveying pipe 6 for connecting the bottom of the sizing shell 4 and the conveying pump 7. The stirring motor 1 is equipped with a stirring rod. A spraying mechanism 2 is installed inside the sizing shell 4. The spraying mechanism 2 is located above the extrusion rollers 3. One side of the spraying mechanism 2 is connected to the output end of the conveying pump 7 through the conveying pipe 6. The spraying mechanism 2 includes symmetrically arranged rotating rollers 26, mounting plates 23 and conveying plates 22 respectively installed at both ends of the two rotating rollers 26.

[0023] The extrusion roller 3 initially extrudes the yarn, controls the amount of sizing and removes excess sizing liquid. In conjunction with the spraying mechanism 2, it can perform a continuous process of soaking, extrusion and secondary spraying, thereby improving the uniformity of sizing liquid distribution.

[0024] The stirring motor 1 and the stirring rod maintain the fluidity of the slurry, help prevent sedimentation, and work together with the internal circulation system to ensure the uniformity of the slurry;

[0025] The rotating roller 26 includes a rotating housing 264, a fixed rod 261 disposed inside the rotating housing 264, a mating ring 262 installed at both ends of the rotating housing 264, and an external toothed ring 263 sleeved on the rotating housing 264. A connecting block 27 is provided at the connection between the mounting plate 23 and the conveying plate 22 and the rotating roller 26. The connecting block 27 engages with the mating ring 262 and rotates. A bidirectional thrust ball bearing 267 is provided between the mating ring 262 and the connecting block 27.

[0026] The spraying mechanism 2 realizes secondary spraying of slurry, which solves the problem of uneven sizing caused by yarn pores. The rotating roller 26 is wrapped by an elliptical rotating shell 264, which encloses the fixed rod 261. The surface has linearly distributed inclined inner holes 265 with the hole diameter facing the squeezing roller 3. The scraper 266 is fixed to the fixed rod 261 and corresponds one-to-one with the inclined inner holes 265. The reciprocating rotation of the rotating shell 264 cleans the sediment in the holes.

[0027] The inclined inner hole 265 is designed with a linearly distributed aperture and faces the extrusion roller 3. High-pressure jetting is used to make the slurry penetrate vertically into the yarn pores, solving the problem of uneven adhesion caused by fiber tension in traditional devices. The reciprocating rotation mechanism rotates the outer shell 264 to make the spraying direction change periodically. Combined with the cleaning of the scraper 266, it ensures long-term stable spraying.

[0028] A plurality of inclined inner holes 265 are provided on the rotating housing 264. The plurality of inclined inner holes 265 are linearly and equally spaced on the rotating housing 264, and the inclined inner holes 265 face the direction of the extrusion roller 3.

[0029] The two ends of the fixing rod 261 are respectively installed on the conveying plate 22 and the mounting plate 23. Several scrapers 266 are installed on the fixing rod 261, and the scrapers 266 correspond to several inclined inner cutting holes 265.

[0030] The rotating housing 264 is elliptical, and the inclined inner hole 265 is located on the outer surface of the elliptical minor diameter of the rotating housing 264. The scraper 266 is engaged with the inclined inner hole 265.

[0031] The scraper 266 and the nozzle work together to fix the relative movement between the scraper 266 and the rotating nozzle, physically breaking the slurry solidification and preventing blockage. The slurry pressure assists the internal circulation pressure and the action of the scraper 266 to form a dual cleaning mechanism.

[0032] The slurry enters the rotating roller 26 under the pressure of the delivery pump 7, and is sprayed onto the yarn under high pressure through the inclined inner hole 265 to fill the fiber gaps. The rotating outer shell 264 is driven to rotate by the drive gear 25, and the doctor blade 266 periodically cuts into the spray hole to break the waxy substance formed by the solidification of the slurry, and achieves self-cleaning in conjunction with the slurry pressure.

[0033] The delivery pump 7 and the delivery pipe 6 form an internal circulation system for the slurry to prevent sedimentation and maintain the spraying pressure. The slurry is drawn from the bottom of the slurry yarn shell 4 and delivered to the spraying mechanism 2 through the delivery pipe 6 to form a dynamic circulation. The pressure drives the slurry to be atomized and sprayed out through the inclined inner hole 265 to enhance permeability.

[0034] A drive gear 25 is also provided on the connecting block 27 on the mounting plate 23. The drive gear 25 is driven by the built-in motor installed on the connecting block 27. The drive gear 25 meshes with the external gear ring 263 to rotate.

[0035] The improved uniformity of sizing allows for secondary spraying to fill yarn pores. The 26 rotating rollers dynamically adjust to ensure all-round penetration of the sizing solution, significantly improving yarn strength and abrasion resistance, preventing sedimentation and self-cleaning. The internal circulation system, combined with rotating spraying, disrupts the crystallization conditions of the sizing solution.

[0036] The 266 scraper mechanism extends equipment maintenance cycles, reduces downtime risks, enhances process adaptability, and its angle and spacing adjustment functions make the device compatible with various yarn types, meeting differentiated production needs and improving equipment utilization. It is suitable for high-count yarns, blended yarns, and other scenarios that require high sizing uniformity, improving fabric quality, reducing downtime caused by sizing sedimentation or blockage, increasing production efficiency, and quickly adjusting spraying parameters to adapt to small-batch, multi-variety order requirements. Example

[0037] Based on Embodiment 1, this utility model provides a technical solution: a novel textile machine sizing device, wherein a rotating shaft 24 is mounted on the mounting plate 23, the rotating shaft 24 is driven to rotate by an external power source, the rotating shaft 24 is rotatably connected to the sizing housing 4, and a connecting joint 21 is provided on the conveying plate 22, the connecting joint 21 is nested and rotated with the conveying pipe 6 on the conveying pump 7, and the connecting joint 21 is rotatably connected to the sizing housing 4.

[0038] The rotating shaft 24 dynamically adjusts the spraying angle and the spacing of the rotating rollers 26 to adapt to different yarn types. An external power source drives the rotating shaft 24 to rotate, changing the angle between the spraying mechanism 2 and the yarn and the roller spacing. Angle adjustment controls the amount of slurry sprayed per unit area, and spacing adjustment optimizes the spraying coverage.

[0039] The spraying mechanism 2 is dynamically adjusted by rotating shaft 24 to match the sizing requirements of different yarns, and the sizing utilization rate is optimized by combining the pressure adjustment of delivery pump 7.

[0040] When the device is running, slurry is poured into the sizing shell 4. The slurry height is lower than the extrusion roller 3. The material enters the sizing shell 4 from one side, and after being soaked in the slurry, it enters the extrusion roller 3 at an angle. After extrusion, it leaves the sizing shell 4. In order to prevent the slurry from solidifying and settling, the conveying pump 7 drives the slurry to be drawn from the bottom of the sizing shell 4 and then conveyed by the conveying pipe 6 to the spraying mechanism 2 installed above the rotating roller 26.

[0041] The slurry enters the conveyor plate 22 through the connecting joint 21. The conveyor plate 22 transfers the slurry to the rotating rollers 26 on both sides. Then, under the internal pressure of the conveyor pump 7, the slurry is sprayed through the inclined inner hole 265 on the conveyor plate 22 onto the material that enters the extrusion roller 3 from the slurry outer shell 4, so that the material can better contact the slurry and prevent uneven slurry adhesion caused by the pore tension between the materials. The slurry completes the internal circulation of the slurry in the device through the spraying mechanism 2, the conveyor pump 7 and the conveying pipe 6, preventing the slurry from solidifying and settling.

[0042] An external gear ring 263 is provided on the rotating housing 264. The external gear ring 263 meshes with the drive gear 25. The drive gear 25 is driven to rotate by a built-in motor installed on the connecting block 27. The built-in motor drives the rotating housing 264 to rotate between the conveying plate 22 and the mounting plate 23. While the rotating housing 264 is rotating, both ends of it are provided with bidirectional thrust ball bearings 267 to reduce the rotational friction between the rotating housing 264 and the conveying plate 22 and the mounting plate 23.

[0043] During the slurry spraying process, the inclined inner holes 265 on the rotating outer shell 264 are linearly distributed, but the slurry only enters the rotating outer shell 264 from one side. The slurry spraying pressure is uneven, and the diameter of the inclined inner holes 265 is small, which easily leads to solidification and blockage. The solidified slurry is waxy. The device's fixing rod 261 is equipped with scrapers 266 corresponding to the inclined inner holes 265. The fixing rod 261 is installed on the conveying plate 22 and the mounting plate 23 and does not rotate with the rotating outer shell 264. The rotating outer shell 264 rotates back and forth, causing the scrapers 266 to continuously cut into the inclined slope when the inclined inner holes 265 rotate back and forth, destroying the waxy deposits that may form in the holes. With the action of slurry pressure, the blockage can be cleared.

[0044] Driven by an external power source, the rotating shaft 24 on the spraying mechanism 2 can rotate. After the rotation angle is formed, the distance between the two rotating rollers 26 can be changed, and the angle between the spraying mechanism 2 and the material being driven obliquely upward can be changed, which means changing the amount of slurry sprayed per unit area on the material being driven, and finally achieving control of the spraying efficiency of the spraying mechanism 2.
