Description

Technical Field

[0001] This utility model relates to the technical field of textile manufacturing equipment, specifically to a fabric winding device for textile manufacturing. Background Technology

[0002] Fabrics are the core material for making clothing, home textiles, industrial products and other products. They come in a wide variety of types and have different characteristics. According to the material, they can be divided into natural fiber fabrics, chemical fiber fabrics and man-made fiber fabrics. Depending on the purpose, fabrics need to undergo a variety of processing techniques such as dyeing, printing, coating and lamination. For example, dyeing can present a variety of colors, digital printing and screen printing can form patterns, and coating or lamination can improve functionality such as waterproofing and wear resistance.

[0003] A search revealed Chinese patent application number 202422133488.7, which discloses a fabric winding device related to fabric processing equipment. This fabric winding device includes a winding assembly for winding fabric, comprising a winding roller and a motor. A winding drum is slidably sleeved on the outer side of the winding roller, and a first flange is fixedly installed on one side of the winding roller. It also includes two sets of clamping components for clamping the winding drum, located inside both sides of the winding roller. This invention utilizes multiple sets of T-blocks inside the winding roller, resulting in a simple and convenient structure. These blocks can move outwards under the push of a push rod and push blocks, simultaneously clamping against the inner wall of the winding drum, thus stably fixing the winding drum onto the winding roller and preventing slippage. Furthermore, by setting a turning column, the movement of the T-blocks can be easily and quickly controlled by rotating the turning column, facilitating rapid loading and unloading of the winding drum by the operator and greatly improving winding efficiency.

[0004] However, existing fabric winding equipment lacks a continuous pressing function for the fabric in actual use. Gaps easily appear between fabric layers during the winding process, resulting in loose rolls. This not only occupies more storage space but also hinders subsequent cutting, sewing, and other finishing processes. Furthermore, it lacks a fabric surface cleaning function, so impurities such as loose threads, lint, and fabric scraps left over from the early processing cannot be removed in time during winding, which directly affects the surface quality of the fabric.

[0005] Therefore, a fabric winding device that combines pressing and anti-loosening functions with surface cleaning is needed to solve the above problems. Utility Model Content

[0006] To address the problems mentioned in the background art, the purpose of this utility model is to provide a fabric winding device for textile manufacturing, which has the advantages of pressing and preventing loosening and surface cleaning. It solves the problems of existing fabric winding devices that lack fabric pressing function, which may cause the rolled material to become loose, hindering subsequent finishing processes, and lack fabric surface cleaning function, which makes it impossible to remove residual threads, lint and other impurities on the fabric surface in a timely manner during the winding process, affecting the surface quality of the fabric.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a fabric winding device for textile manufacturing, comprising a winding device body, a winding drum, and fabric, wherein the fabric is wound around the surface of the winding drum and one end is fixedly connected to the winding drum; a pressing component is provided on the top of the winding device body; and a cleaning mechanism is provided on the front side of the winding device body.

[0011] In a preferred embodiment of this invention, the scraping assembly includes a scraper, the rear side of which contacts the surface of the fabric, a support block is fixedly connected to the middle of the front side of the scraper, and a connecting plate is fixedly connected to the left side of the front side of the scraper.

[0012] As a preferred embodiment of this utility model, two support columns are fixedly connected to the front side of the main body of the winding device, and a stop block is fixedly connected to the front side of the support column. The side of the connecting plate away from the scraper is sleeved on the surface of the support column and is slidably connected to the support column through a linear bearing. Extrusion columns are fixedly connected to the left and right sides of the inner side of the support block.

[0013] As a preferred embodiment of this utility model, the linkage component includes a linkage plate, which is located inside the support block and is fixedly connected to the lower pressure plate at its rear. The linkage plate has extrusion grooves on both its left and right sides.

[0014] The extrusion groove is inclined, and the side of the extrusion column away from the support block passes through the extrusion groove and extends into the inner cavity of the extrusion groove to contact the inner wall of the extrusion groove.

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

[0016] 1. This utility model solves the problems of existing fabric winding equipment lacking a fabric clamping function, which may cause the roll to become loose, hindering subsequent processing, and lacking a fabric surface cleaning function, making it impossible to remove residual threads, lint, and other impurities on the fabric surface during winding, thus affecting the surface quality of the fabric. It achieves the effect of effectively clamping the fabric to prevent the roll from becoming loose, while simultaneously cleaning the fabric surface, thus not only facilitating subsequent processing of the fabric roll, but also improving the surface quality of the fabric.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention.

[0028] Example 1

[0029] Reference Figure 1-3 This is the first embodiment of the present invention, which provides a fabric winding device for textile manufacturing, including a winding device body 1, a winding drum 2, and fabric 3. The fabric 3 is wound around the surface of the winding drum 2, and one end is fixedly connected to the winding drum 2. A pressing component 4 is provided on the top of the winding device body 1, and a cleaning mechanism 5 is provided on the front side of the winding device body 1.

[0030] The cleaning mechanism 5 includes a scraping component 51, and a linkage component 52 that works in conjunction with the clamping component 4 is provided on the inner side of the scraping component 51.

[0031] Specifically, by setting the pressing component 4, the fabric 3 can be continuously pressed, avoiding gaps between the layers of fabric 3 during the winding process, which would cause the roll to loosen and facilitate subsequent handling of fabric 3.

[0032] By setting up the scraping component 51, it can directly contact the surface of the fabric 3 to scrape off the residual thread ends, lint and other impurities during the winding process in real time, reducing the impact of impurity adhesion on the surface quality of the fabric 3.

[0033] By setting the linkage component 52, the linkage between the pressing component 4 and the scraping component 51 can be realized. When the pressing component 4 moves adaptively as the diameter of the fabric roll 3 increases, the scraping component 51 is driven to adjust its position synchronously, ensuring that the scraping component 51 always keeps in contact with the surface of the fabric 3, thus ensuring the continuity of the cleaning effect.

[0034] Furthermore, when the winding equipment is working, the winding drum 2 is driven to rotate, and the rotation of the winding drum 2 causes the fabric 3 to wind around. The pressing component 4 applies pressure to the winding fabric 3 to prevent it from loosening. The cleaning mechanism 5 cleans surface impurities through the scraping component 51, and the linkage component 52 realizes the synchronous movement of the two to adapt to changes in the diameter of the roll.

[0035] Example 2

[0036] In the second embodiment of this utility model, the pressing assembly 4 includes two sliding columns 41 and a lower pressure plate 42. The bottom of the sliding column 41 is fixedly connected to the main body 1 of the winding device. The left side of the lower pressure plate 42 is sleeved on the surface of the sliding column 41 and is slidably connected to the sliding column 41 through a linear bearing. Positioning blocks 43 are fixedly connected to the left and right sides of the bottom of the lower pressure plate 42.

[0037] A limiting plate 44 is fixedly connected to the top of the sliding column 41. A spring 45 is sleeved on the surface of the sliding column 41. The top and bottom of the spring 45 are fixedly connected to the limiting plate 44 and the lower pressure plate 42, respectively. The inner side of the positioning block 43 is rotatably connected to the pressing roller 46. The bottom of the pressing roller 46 is in contact with the surface of the fabric 3.

[0038] Specifically, by setting up a spring 45, a lower pressure plate 42 and a pressing roller 46, the elastic force of the spring 45 provides continuous downward pressure to the lower pressure plate 42, so that the pressing roller 46 is always in close contact with the surface of the fabric 3, effectively preventing the fabric 3 from loosening between layers;

[0039] By setting the sliding column 41, the lower pressure plate 42 can be limited, and the linear bearing reduces the friction between the lower pressure plate 42 and the sliding column 41, ensuring that the lower pressure plate 42 rises smoothly along the sliding column 41 as the diameter of the roll increases, adapting to the pressing requirements of different roll diameters.

[0040] By setting a limiting plate 44 and a positioning block 43, the limiting plate 44 can prevent the lower pressure plate 42 from detaching from the top of the sliding column 41, and the positioning block 43 can provide stable support for the pressing roller 46.

[0041] Furthermore, in the initial state, the spring 45 is in a naturally extended state. Under the pressure of the spring 45, the lower pressure plate 42 drives the pressure roller 46 to press against the surface of the fabric 3, applying an initial clamping force. As the winding proceeds, the roll diameter of the fabric 3 gradually increases, and the roll generates an upward thrust on the pressure roller 46, pushing the lower pressure plate 42 to slide upward along the sliding column 41 and compress the spring 45. The reaction force of the spring 45 ensures that the pressure roller 46 always maintains effective pressure on the fabric 3, achieving continuous clamping.

[0042] Example 3

[0043] In the third embodiment of this utility model, the scraping component 51 includes a scraper 511. The rear side of the scraper 511 contacts the surface of the fabric 3. A support block 512 is fixedly connected to the middle of the front side of the scraper 511, and a connecting plate 513 is fixedly connected to the left side of the front side of the scraper 511.

[0044] Two support columns 6 are fixedly connected to the front side of the main body 1 of the winding equipment. A stop block 7 is fixedly connected to the front side of the support column 6. The side of the connecting plate 513 away from the scraper 511 is sleeved on the surface of the support column 6 and is slidably connected to the support column 6 through a linear bearing. Extrusion columns 8 are fixedly connected to the left and right sides of the inner side of the support block 512.

[0045] Specifically, by setting a scraper 511, which is in direct contact with the surface of the fabric 3, it can scrape off the remaining threads, lint and other impurities during the winding process in real time, thereby improving the cleanliness of the fabric 3 surface.

[0046] By setting up a support column 6, a connecting plate 513 and a linear bearing, the support column 6 provides motion support for the scraper 511, and the connecting plate 513 slides along the support column 6 through the linear bearing, so that the scraper 511 can adjust its front and rear position according to the change of roll diameter, ensuring the fit with the surface of the fabric 3.

[0047] By setting the stop 7 and the squeezing column 8, the stop 7 can limit the connection plate 513, and the squeezing column 8 can transmit the movement of the linkage component 52 to the scraping component 51.

[0048] Furthermore, during winding, the scraper 511 contacts the surface of the fabric 3 at the initial position and continuously scrapes away impurities as the fabric 3 moves. When the roll diameter of the fabric 3 changes, the extrusion column 8 is forced to drive the support block 512 and the scraper 511 to slide back and forth along the support column 6 through the connecting plate 513, so that the scraper 511 moves synchronously with the change of the roll diameter and maintains contact with the surface of the fabric 3 to clean the surface of the fabric 3.

[0049] Example 4

[0050] In the fourth embodiment of this utility model, the linkage component 52 includes a linkage plate 521, which is located inside the support block 512 and is fixedly connected to the lower pressure plate 42 at its rear. The linkage plate 521 has extrusion grooves 522 on both its left and right sides.

[0051] The extrusion groove 522 is inclined, and the side of the extrusion column 8 away from the support block 512 passes through the extrusion groove 522 and extends into the inner cavity of the extrusion groove 522 to contact the inner wall of the extrusion groove 522.

[0052] Specifically, by setting up a linkage plate 521, which is fixedly connected to the lower pressure plate 42, the movement of the pressing component 4 can be synchronously transmitted to the scraping component 51, realizing the linkage between the two;

[0053] By setting an inclined extrusion groove 522 and an extrusion column 8, the inclined surface of the extrusion groove 522 is used for extrusion. When the linkage plate 521 moves with the lower pressure plate 42, the inner wall of the extrusion groove 522 generates a horizontal thrust on the extrusion column 8, driving the scraping component 51 to slide along the support column 6. The pressing component 4 and the scraping component 51 can move synchronously without an additional power source.

[0054] Furthermore, when the roll diameter of fabric 3 increases, the lower pressure plate 42 moves upward along the sliding column 41, driving the linkage plate 521 to rise synchronously. The inner wall of the inclined extrusion groove 522 generates a backward thrust on the extrusion column 8, pushing the extrusion column 8 to drive the support block 512 and the scraper 511 to slide backward along the support column 6, so that the scraper 511 always adheres to the surface of the roll.

[0055] Working principle:

[0056] During operation, one end of the fabric 3 is fixed on the take-up drum 2, the spring 45 in the pressing assembly 4 is in a naturally extended state, the lower pressure plate 42 drives the pressing roller 46 to contact the surface of the fabric 3 under the pressure of the spring 45, and applies the initial pressing force, the scraper 511 in the scraping assembly 51 contacts the surface of the fabric 3, and the extrusion column 8 passes through the extrusion groove 522 of the linkage plate 521 and contacts the groove wall, and is in the initial position;

[0057] During the winding process, the winding drum 2 rotates under the driving action of the main body 1 of the winding equipment, which drives the fabric 3 to gradually wind and form a roll. At this time, the pressure roller 46 is pressed against the surface of the fabric 3 under the continuous pressure of the spring 45, which compacts each layer of the wound fabric 3 to avoid gaps between layers that cause the roll to loosen. At the same time, the scraper 511 moves with the fabric 3 and scrapes off the residual thread ends, lint and other impurities on the surface of the fabric 3 in real time, improving the surface quality of the fabric 3.

[0058] As the fabric 3 is wound up, the diameter of the fabric 3 gradually increases, and the upward pushing force of the fabric on the pressure roller 46 increases. This pushes the lower pressure plate 42 to slide upward along the sliding column 41 and compresses the spring 45. The reaction force of the spring 45 ensures that the pressure roller 46 always maintains an effective pressing force on the fabric 3. As the lower pressure plate 42 rises, it drives the fixedly connected linkage plate 521 to rise synchronously. The inner walls of the inclined extrusion grooves 522 on both sides of the linkage plate 521 generate a backward horizontal pushing force on the extrusion column 8 of the scraping component 51. This pushes the extrusion column 8 to drive the support block 512 and the scraper 511 to slide backward along the support column 6 through the connecting plate 513, so that the scraper 511 always adheres to the surface of the fabric roll, ensuring a continuous cleaning effect.

[0059] When the winding is completed and the roll is changed, the roll is removed. The lower pressure plate 42 is reset downward along the sliding column 41 under the elastic force of the spring 45. The linkage plate 521 moves downward accordingly. The inner wall of the extrusion groove 522 generates a forward thrust on the extrusion column 8, pushing the scraper 511 forward along the support column 6 through the connecting plate 513 to reset to the initial position, preparing for the next winding.

[0060] In summary, by using the pressing component 4 and the cleaning mechanism 5 in combination, the fabric can be effectively pressed to prevent the roll from loosening, while the fabric surface can be cleaned simultaneously. This not only facilitates the subsequent handling of the fabric roll, but also improves the surface quality of the fabric.
