Description

Technical Field

[0001] This utility model relates to the field of woven fabric winding technology, and in particular to a structure for winding waste plastic woven fabric. Background Technology

[0002] In existing technologies, defects and unevenness often occur on the edges of woven fabrics during production, requiring the removal of waste material before recycling via take-up rollers. Traditional cylindrical take-up rollers form a tightly packed roll after the waste material is wrapped around it, requiring manual peeling or prying with tools during unloading, resulting in low efficiency and safety hazards. Especially when the waste layer is thick, the increased friction between it and the roller surface makes removal difficult, directly affecting the continuity of waste recycling. Utility Model Content

[0003] The purpose of this utility model is to provide a structure for winding plastic woven fabric waste to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0004] The technical solution adopted to solve the above-mentioned technical problems is as follows:

[0005] This utility model provides a structure for winding waste plastic woven fabric, including a rotating structure and a rotating drive unit. The rotating structure includes a rotating base, a support rod, and at least three winding rods. The support rod and the at least three winding rods are all located on the rotating base. The rotating base has a rotating axis, and the support rod and the at least three winding rods are parallel to the rotating axis. The support rod is located in the middle of the at least three winding rods, with a fixed end and a material-taking end at both ends. The fixed end is located on the rotating base, and a bushing is slidably fitted onto the material-taking end. The bushing is connected to the three winding rods via a connecting rod. A return spring is provided between the bushing and the support rod. The return spring provides an elastic force to move the bushing and the connecting rod away from the material-taking end, thereby moving the three winding rods away from the support rod. The rotating drive unit drives the rotating base to rotate around the rotating axis.

[0006] The beneficial effects of this utility model are:

[0007] Under normal conditions, the return spring provides elastic force to push the three winding rods outward. The rotary drive unit drives the rotating seat to rotate, causing at least three winding rods to rotate and wind up the material. After winding, the bushing is pushed to compress the return spring, and the at least three winding rods move closer to the central support rod. There is a gap between the inside of the wound material and the at least three wound rods after shrinking, which allows the wound material to be easily separated from the at least three winding rods, making material removal easy. After removing the material, the bushing is loosened, and the return spring provides elastic force to push the at least three winding rods outward, allowing the at least three winding rods to return to the wound state.

[0008] As a further improvement to the above technical solution, the material receiving end is provided with a material blocking part, and the bushing is provided with an abutting part that abuts against the material blocking part.

[0009] As a further improvement to the above technical solution, both the material stop and the abutment part are annular steps.

[0010] As a further improvement to the above technical solution, the support rod is provided with an annular boss, the return spring is sleeved on the support rod, and the two ends of the return spring are respectively connected to the annular boss and the bushing.

[0011] As a further improvement to the above technical solution, the connecting rod is hinged to the bushing and the coil rod respectively.

[0012] As a further improvement to the above technical solution, the side of the rotating seat is provided with two spaced-apart fixing blocks, and the connecting rod is provided with a connecting block inserted into the two fixing blocks. The connecting block is fixed to the two fixing blocks by screws.

[0013] As a further improvement to the above technical solution, at least three of the coil rods are evenly distributed on the outer periphery of the support rod.

[0014] As a further improvement to the above technical solution, the support rod and at least three coil rods are all provided with a smooth layer.

[0015] As a further improvement to the above technical solution, the support rod and at least three coil rods are metal components.

[0016] As a further improvement to the above technical solution, a flexible layer is provided on the outer side of the bushing. Attached Figure Description

[0027] Therefore, refer to Figures 1 to 3 The following are embodiments of the plastic woven fabric waste winding structure of this utility model:

[0028] The woven fabric waste winding structure includes a rotating structure 100 and a rotating drive unit 200. The rotating structure 100 includes a rotating base 110, a support rod 120, and four winding rods 130. The support rod 120 is fixed to the center of the rotating base 110, and the winding rods 130 are arranged around the support rod 120. The material-taking end of the support rod 120 is slidably sleeved with a bushing 140. The bushing 140 is hinged to each winding rod 130 via a connecting rod 160. A return spring 150 acts between the bushing 140 and the support rod 120 to provide elastic support. The rotating drive unit 200 drives the rotating base 110 to rotate around its axis. The connecting rod 160 is hinged to both the bushing 140 and the winding rods 130. Specifically, the hinge can be achieved using a pin-and-hole mating structure, for example, by providing through holes at both ends of the connecting rod 160 and connecting it to the mounting holes on the bushing 140 or the winding rods 130 via pins. This structure allows relative rotation between the connecting rod 160 and the winding rod 130, thereby changing the radial position of the winding rod 130 when the bushing 140 moves axially.

[0029] The rotating base 110 refers to the rotating base that supports the support rod 120 and the coiling rod 130. Specifically, it can be a flange or a disc structure, with its axis parallel to the support rod 120 to ensure synchronous movement of all components during rotation. The support rod 120 serves as the central axis, with its fixed end rigidly connected to the rotating base 110. The material-taking end is provided with a sliding mating surface, and a chrome-plated steel rod can be used to improve wear resistance.

[0030] Four winding rods 130 are provided, evenly distributed around the outer periphery of the support rod 120. This ensures that the radial distance between each winding rod 130 and the support rod 120 remains consistent. When waste woven fabric is wound around the surface of the winding rods 130, the four winding rods 130 form a ring structure, causing the waste to simultaneously form a winding layer of equal thickness on the surface of each winding rod 130. The ring structure cancels out the radial forces generated during the waste winding process, preventing eccentricity of the winding layer caused by unilateral accumulation. After waste collection is completed, the return spring 150 pushes the bushing 140 to synchronously retract the winding rods 130 radially. At this time, the evenly distributed surfaces of the winding rods 130 and the waste layer form a uniform gap expansion, ensuring that the waste layer is completely detached from the winding rods 130. In some other embodiments, the number of winding rods 130 may be three.

[0031] The bushing 140 is a sliding component that fits onto the support rod 120. It can be made of copper-based alloy sleeve to reduce the coefficient of friction. Its axial movement drives the connecting rod 160 to change the radial position of the coil rod 130. The outer side of the bushing 140 is provided with a flexible layer, specifically made of rubber, which makes it more comfortable to press.

[0032] The connecting rod 160 serves as a transmission component, with its two ends hinged to the bushing 140 and the winding rod 130, respectively. The return spring 150 is preferably a helical compression spring, which, under normal conditions, pushes the bushing 140 to move away from the material-taking end, keeping the winding rod 130 at its maximum unfolded diameter. The rotary drive unit 200 can be a motor with a reducer, connected to the rotating base 110 via a coupling.

[0033] Specifically, during the winding operation, the return spring 150 pushes the bushing 140 outward, and the connecting rod 160 expands the winding rod 130 to its maximum unfolded state. The rotary drive unit 200 drives the rotating seat 110 to rotate at a constant speed, and the waste material is sequentially wound around the three-dimensional frame formed by the winding rod 130 and the support rod 120. During unloading, the operator pushes the bushing 140 along the axial direction of the support rod 120 to compress the return spring 150, and the connecting rod 160 drives the winding rod 130 to retract towards the center, forming a gap between the waste roll and the winding rod 130, allowing the waste roll to be easily removed. The support rod 120 serves as a fixed reference axis to ensure that the winding rod 130 does not wobble during rotation. The triangular support structure formed by the three winding rods 130 evenly distributes the tension of the waste material during winding, avoiding local deformation.

[0034] Compared with existing technologies, traditional cylindrical take-up rollers have a fixed diameter structure, while this solution achieves dynamic diameter change through a telescopic take-up rod 130, uses mechanical linkage to achieve rapid shrinkage and demolding, and reduces frictional resistance through multi-point contact.

[0035] Furthermore, a stop portion 121 is provided at the material-taking end, and an abutment portion 141 is provided on the bushing 140 to abut against the stop portion 121. The stop portion 121 is a limiting component located at the material-taking end of the support rod 120 to prevent axial movement of the bushing 140. Specifically, it can be implemented using an annular step structure. The annular step is formed on the surface of the support rod 120 by machining, and its outer diameter is larger than the diameter of the support rod 120 body, thus limiting the travel of the bushing 140. The abutment portion 141 is a limiting component located on the inner wall of the bushing 140 and cooperating with the stop portion 121. Specifically, it can be implemented using an annular step structure that matches the shape of the stop portion 121. The annular step is formed on the inner wall of the bushing 140 by turning, and its inner diameter is smaller than the outer diameter of the stop portion 121, thus forming a physical blockage through contact with the stop portion 121.

[0036] When the bushing 140 moves away from the material-taking end under the elastic force of the return spring 150, the abutment part 141 contacts the stop part 121. At this time, the axial displacement of the bushing 140 is restricted, thereby preventing the connecting rod 160 from driving the winding rod 130 to continue to expand outward. When it is necessary to disassemble the wound waste, the operator overcomes the elastic force of the return spring 150 and pushes the bushing 140 in the opposite direction to the material-taking end. At this time, the abutment part 141 disengages from the stop part 121, the winding rod 130 retracts inward, the contact pressure between the waste and the support rod 120 is released, and the waste can be easily removed. This solution, through the rigid contact limitation between the stop part 121 and the abutment part 141, precisely controls the movement stroke of the winding rod 130, avoiding the problem of waste slippage caused by structural loosening.

[0037] Furthermore, the support rod 120 is provided with an annular boss 122, and a return spring 150 is sleeved on the support rod 120. The two ends of the return spring 150 are connected to the annular boss 122 and the bushing 140, respectively. The annular boss 122 refers to the annular protrusion structure formed on the surface of the support rod 120, which can be formed by welding an annular metal part or machining the outer surface of the support rod 120, and is used to limit the axial position of the return spring 150. The return spring 150 is sleeved on the support rod 120 because the inner diameter of the spring is slightly larger than the outer diameter of the support rod 120, allowing the spring to extend and retract along the axial direction of the support rod 120, avoiding radial displacement of the spring and resulting frictional loss. The annular boss 122 is positioned at a specific location on the support rod 120, with one end of the return spring 150 directly pressing against the side of the boss, and the other end rigidly connected to the bushing 140. When the bushing 140 slides towards the material-taking end under external force, the spring is compressed and stores elastic potential energy. After the external force disappears, the spring pushes the bushing 140 to move in the opposite direction along the axis of the support rod 120, causing the coiling rod 130 to return to its original position synchronously. By rigidly limiting the end of the spring with the annular boss 122, the compression stroke of the spring is precisely controlled in the axial direction of the support rod 120, avoiding the attenuation of the return force caused by the spring tilting or radial offset, and significantly improving the stability of the return direction.

[0038] Furthermore, the rotating base 110 has two spaced-apart fixing blocks 111 on its side. The connecting rod 160 has a connecting block inserted into the two fixing blocks 111, and the connecting block is fixed to the two fixing blocks 111 by screws 170. The fixing blocks 111 are two parallel and spaced-apart block structures, the spacing of which allows the connecting block to be inserted and form a clamping and fixing relationship. Specifically, this can be achieved by welding metal blocks or bolting them to the side of the rotating base 110, providing a detachable fixing point for the connecting rod 160. When it is necessary to disassemble the connecting rod 160, simply loosen the screws 170 to pull the connecting block out from between the fixing blocks 111, thereby releasing the constraint between the connecting rod 160 and the rotating base 110. The spaced design of the fixing blocks 111 means that the connecting block does not require precise alignment during installation; initial positioning can be completed simply by inserting it along the gap direction of the fixing blocks 111.

[0039] Furthermore, the support rod 120 and at least three winding rods 130 are all provided with a smooth layer. The smooth layer refers to a low-friction material layer covering the surface of the support rod 120 and the winding rods 130. Specifically, it can be achieved by electroplating or spraying to form a polytetrafluoroethylene coating. This layer reduces the contact friction with the woven fabric waste by reducing surface roughness, making it easier to remove the cylindrical waste.

[0040] Furthermore, the support rod 120 and at least three coil rods 130 are all made of metal components. Metal components refer to structural parts made of metal materials, specifically stainless steel, aluminum alloy, or carbon steel, which possess high yield strength and tensile strength. During the waste winding process, the metal support rod 120 and coil rods 130 resist bending deformation caused by winding tension through the rigidity of the material itself, while relying on the wear resistance of the metal to reduce surface wear, thus preventing waste winding failure due to structural deformation.

[0041] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
