Description

Technical Field

[0001] This utility model relates to the field of textile machinery, and in particular to a textile fabric winding and unloading device. Background Technology

[0002] In the production and post-processing of textile fabrics, winding is an indispensable step, and its efficiency and quality directly affect the convenience and cost of fabric storage, transportation, and subsequent processing. Existing textile fabric winding and unloading devices have made significant progress, gradually incorporating automation and intelligent technologies to improve production efficiency, reduce manual labor intensity, and ensure winding quality. For example, some existing technologies focus on using air pressure or mechanical expansion to support the roll and ensure winding tightness; others attempt to use sensors to monitor the winding diameter for preliminary control of the winding amount; still others focus on solving the problem of automated unloading of the roll to reduce the burden of manual handling.

[0003] However, while existing technologies achieve integration, they often come with problems such as complex structures, high manufacturing costs, and difficult maintenance. This is especially true when addressing a series of interconnected processes, including initial fabric fixing, fabric smoothing and tension control during winding, and cutting and unloading after winding. For example, while some devices automate the initial winding fixing, they lack effective handling of fabric wrinkles and air bubbles during winding; some devices have automated cutting functions, but their cutting mechanisms may be integrated inside the roll, leading to complex structures and inconvenient maintenance. Therefore, the textile fabric winding field urgently needs a new type of device that can integrate key functions while maintaining a simple, efficient, and easy-to-maintain structure, and achieving full automation of the winding process. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a textile fabric winding and unloading device to resolve the contradiction between integration and structural complexity in the prior art. The device aims to achieve functions such as fixing the initial end of the fabric, flattening and tension control during the winding process, intelligent detection of the winding amount, and automated cutting and unloading after winding, while maintaining a simple structure that is easy to manufacture and maintain.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A textile fabric winding and unloading device includes: a base; a main winding drive unit disposed on one side of the base; a movable support seat disposed on the other side of the base and slidably connected to the base via a guide rail, enabling reciprocating movement in the horizontal direction to support and release the main winding shaft; the main winding shaft being transversely disposed above the base, with one end connected to the main winding drive unit and the other end supported by the movable support seat, and a slot being formed along the axial direction on the circumferential surface of the main winding shaft; a retractable magnetic clamping strip disposed inside the slot of the main winding shaft, capable of radial extension and retraction within the slot to clamp and release the initial end of the fabric; a pressure roller disposed above the fabric feeding direction of the main winding shaft and parallel to the main winding shaft, used to apply pressure to the fabric during the winding process to eliminate wrinkles and air bubbles; a cutting device disposed below or to the side of the main winding shaft and slidably connected to the base via a guide rail, used to move in the transverse direction to cut the fabric; and an inclined discharge chute disposed directly below the main winding shaft, used to adjust the inclination angle to achieve automated unloading of the roll.

[0007] Preferably, the retractable magnetic clamping strip is connected to a drive mechanism located inside the main winding shaft via a push rod mechanism.

[0008] Preferably, the movable support is driven by a lead screw mechanism.

[0009] Preferably, the pressure roller is connected to the base via a support arm, which is equipped with an adaptive mechanism that allows the pressure roller to float up and down and always remain in contact with the fabric being wound.

[0010] Preferably, the cutting device is driven by a drive mechanism.

[0011] Preferably, one end of the inclined discharge chute is hinged to the base via a pivot, and the other end is connected to a push rod. The inclination angle of the chute is adjusted by controlling the extension and retraction of the push rod.

[0012] Preferably, the main winding drive unit includes a motor and a reduction mechanism, with the motor connected to the main winding shaft via the reduction mechanism.

[0013] Preferably, it also includes an unloading assembly, which is mounted on a movable support and includes: a long rod with a length greater than the length of the main winding shaft; and a stop bar disposed between the surface of the long rod and the main winding shaft. The movable support, together with the unloading assembly, can move along a linear guide rail and push the cylindrical textile fabric off the main winding shaft under the push of the stop bar.

[0014] The beneficial effects of this utility model include the following:

[0015] 1. By setting a retractable magnetic clamping strip, the fabric end can be quickly and securely fixed without damage. Combined with the reciprocating movement of the movable support base, the main winding shaft end can be quickly supported and released. In addition, the inclined discharge chute provides an automated tilting unloading function. The fabric end fixing and roll unloading functions are efficiently integrated, which effectively solves the problems of low fabric end fixing efficiency and low degree of unloading automation, and significantly improves the automation level and ease of operation of the winding operation.

[0016] 2. By integrating pressure rollers, uniform pressure can be applied to the fabric during winding, effectively eliminating wrinkles and bubbles on the fabric surface and ensuring the flatness and quality of the winding. At the same time, the cutting device enables automated transverse cutting of the fabric after winding, avoiding the limitations of traditional production lines that require multiple independent devices or additional processes to complete these tasks. This achieves higher production efficiency and consistency in winding quality, while maintaining the overall structure of the device as simple, easy to manufacture and maintain.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments, but these specific embodiments do not limit the scope of protection of the present invention in any way. Example

[0024] like Figure 1-5 As shown, a textile fabric winding and unloading device includes a base 1, a main winding drive unit 2, a movable support base 3, a main winding shaft 4, a retractable magnetic clamping strip 6, a pressure roller 10, a transverse cutting blade 11, and an inclined discharge chute 12. This winding device is mainly used for automated winding operations of textile fabrics, enabling functions such as fixing the initial end of the fabric, flattening and tension control during the winding process, intelligent detection of the winding amount, and automated cutting and unloading after winding, while maintaining a simple structure that is easy to manufacture and maintain.

[0025] The base 1 serves as the main frame of the entire device, providing a stable support structure. Adjustable feet are provided at the bottom to ensure the stability of the device under various ground conditions. The surface of the base 1 is treated with rust prevention to extend its service life.

[0026] The main winding drive unit 2 is located on one side of the base 1 and includes a motor 21 and a reduction mechanism. The motor 21 is a high-performance servo motor 21, and the reduction mechanism is a planetary reducer 22, which can convert the high speed of the motor 21 into a low-speed, high-torque output suitable for fabric winding. The main winding drive unit 2 is directly connected to one end of the main winding shaft 4 through a high-strength coupling to ensure the reliability and accuracy of power transmission.

[0027] The movable support 3 is located on the other side of the base 1 and is slidably connected to the base 1 via a linear guide 31. The linear guide 31 is a ball bearing guide, which can ensure the smooth movement of the movable support 3 in the horizontal direction. The movable support 3 is driven by a screw mechanism, which can realize the reciprocating movement of the movable support 3 in the horizontal direction. The center of the movable support 3 is provided with a bearing seat to support the free end of the main winding shaft 4.

[0028] The main winding shaft 4 is horizontally positioned above the base 1. One end of it is connected to the main winding drive unit 2, and the other end is supported by the movable support seat 3. The surface of the main winding shaft 4 is polished. A rectangular slot 5 that runs through the entire length is opened along the axial direction on the circumferential surface of the main winding shaft 4. The width and depth of the slot are designed according to the fabric thickness and serve as an insertion slot for the beginning of the fabric.

[0029] A retractable magnetic clamping strip 6 is disposed inside a rectangular slot 5 of the main winding shaft 4, and its length is the same as the slot length. The main body of the clamping strip is made of non-magnetic material, and several permanent magnets 7 are embedded in its side facing the slot. The permanent magnets 7 are evenly distributed along the length of the clamping strip to ensure uniform clamping force on the initial end of the fabric. The magnetic clamping strip is connected to a miniature cylinder mechanism 9, which is also disposed inside the main winding shaft 4, through a push rod mechanism 8 inside the main winding shaft 4. The miniature cylinder mechanism 9 can drive the magnetic clamping strip to perform radial extension and retraction within the rectangular slot 5. When the clamping strip extends outward, its permanent magnets 7 generate magnetic attraction with the initial end of the fabric inserted into the slot, achieving reliable clamping of the fabric; when the clamping strip retracts inward, it releases the clamping force on the fabric, facilitating the removal of the fabric.

[0030] The pressure roller 10 is positioned above the main winding shaft 4 in the fabric feeding direction, parallel to the main winding shaft 4. The pressure roller 10 applies appropriate pressure to the fabric during winding, eliminating wrinkles and air bubbles on the fabric surface. This roller is connected to the base 1 via a support arm, which is equipped with a gravity-adaptive mechanism or a small cylinder, allowing the pressure roller 10 to float up and down while maintaining constant contact with the fabric during winding. The gravity-adaptive mechanism, implemented through a counterweight and spring system, automatically adjusts the pressure according to changes in fabric thickness and winding diameter.

[0031] The transverse cutting blade 11 is positioned below the main winding shaft 4 and is slidably connected to the base 1 via a linear guide rail. The linear guide rail is parallel to the main winding shaft 4 and fixed to the base 1 to ensure accurate movement of the cutting blade. The cutting blade is driven by a small motor 21 and can move rapidly in the transverse direction. The cutting head can be a rotary circular blade or a reciprocating blade. The rotary circular blade is suitable for continuous cutting, while the reciprocating blade is suitable for precise positioning cutting. The cutting head is positioned at the end of the fabric winding path, and after the fabric is wound, the cutting blade can accurately cut the fabric transversely.

[0032] An inclined discharge chute 12 is positioned directly below the main winding shaft 4, with a U-shaped or V-shaped cross-section, capable of supporting and guiding the wound fabric roll. One end of the chute is hinged to the base 1 via a pivot, and the other end is connected to an electric push rod 121, one end of which is fixed to the base 1, and the other end is hinged to the bottom of the chute. By controlling the extension and retraction of the electric push rod 121, the inclination angle of the chute can be adjusted, allowing the wound fabric roll to slide smoothly to the external collection area. The inner surface of the chute is smooth, reducing frictional resistance during the sliding of the fabric roll. Furthermore, a material unloading assembly 13 is provided on the movable support 3 facing the main winding drive unit 2. The material unloading assembly 13 is a structure of a long rod 131 and a stop rod 132. The length of the long rod 131 is greater than the length of the main winding shaft 4. The stop rod 132 is set on the surface of the long rod 131 and the main winding shaft 4. The height of the stop rod 132 is slightly less than the height between the long rod 131 and the main winding shaft 4. After the winding of the textile fabric is completed, the movable support 3 together with the structure of the long rod 131 and the stop rod 132 moves along the linear guide rail 31 to the opposite side of the main winding shaft 4. Under the push of the stop rod, the textile fabric wound into a cylindrical shape is pulled off the main winding shaft 4 and falls into the discharge chute 12.

[0033] The working principle and method of the above-mentioned textile fabric winding and unloading device are as follows:

[0034] The first step involves the operator inserting the beginning end of the fabric to be wound into the rectangular slot 5 of the main winding shaft 4, to a depth of approximately one-tenth of the fabric width. The control system activates the micro-cylinder mechanism 9, driving the retractable magnetic clamping strip 6 to extend outwards. The permanent magnet 7 on the clamping strip generates a magnetic attraction with the beginning end of the fabric, firmly clamping it within the slot. At this time, the movable support base 3 is in the support position, ensuring the stability of the main winding shaft 4.

[0035] The second step involves activating the main winding drive unit 2. The servo motor 21 drives the main winding shaft 4 to rotate via a reduction mechanism. Simultaneously, the pressure roller 10, under the action of a gravity-adaptive mechanism or a cylinder, maintains contact with the fabric being wound, applying appropriate pressure. As the main winding shaft 4 rotates, the fabric gradually winds onto the shaft. The pressure roller 10 eliminates wrinkles and air bubbles on the fabric surface, ensuring winding quality. During the winding process, the control system monitors changes in the winding diameter via an encoder or other sensors, achieving precise control of the winding amount.

[0036] Third, when the fabric winding reaches the preset diameter or length, the control system automatically stops the rotation of the main winding drive unit 2. At this time, the transverse cutting blade 11, driven by the motor 21, moves rapidly along the linear guide rail to cut the fabric transversely. After cutting, the cutting blade returns to its initial position, waiting for the next cutting operation.

[0037] In the fourth step, after the fabric is cut, the control system activates the micro cylinder mechanism 9, causing the retractable magnetic clamping strip 6 to retract inward and release the clamping of the initial end of the fabric. At the same time, the movable support seat 3 moves outward along the linear guide rail 31 under the drive of the screw mechanism, causing the free end of the main winding shaft 4 to disengage from the bearing seat support. Simultaneously, the long rod 131 and the stop rod 132 structure move along the linear guide rail 31 to the opposite side of the main winding shaft 4. Under the push of the stop rod, the textile fabric wound into a tube shape is pulled off the main winding shaft 4, and the textile fabric falls into the discharge chute 12.

[0038] Fifth, the control system activates the electric push rod 121 below the inclined discharge chute 12, tilting the chute to a suitable angle. Under gravity, the wound fabric roll smoothly slides along the inclined chute to the external collection area, completing the automated unloading. After unloading, the chute returns to a horizontal position, preparing for the next winding operation.

[0039] In the sixth step, the movable support 3 moves inward along the linear guide 31 under the drive of the screw mechanism, and supports the free end of the main winding shaft 4 again, ready for the next fabric winding operation.

[0040] This device achieves full automation of the textile fabric winding process through the coordinated operation of its various components. This not only improves production efficiency and reduces manual labor intensity but also ensures consistent winding quality. Furthermore, the device has a relatively simple structure, low manufacturing cost, and is easy to maintain, making it highly practical and economical.

[0041] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any innovative improvements or substitutions based on the present invention should fall within the scope of the claims of the present invention. Furthermore, the parameters, materials, and processes mentioned in the above embodiments are not unique. Without departing from the technical essence of the present invention, those skilled in the art can make various alternative choices, and these alternative solutions should also be considered to fall within the scope of protection of the present invention.
