Description

Technical Field

[0001] This utility model relates to the field of winding equipment technology, specifically a single-axis high-speed winding mechanism based on a metal roll paper sleeve. Background Technology

[0002] Metal coils require high-speed winding to achieve continuous production during rolling, coating and other processing.

[0003] According to the patent titled "A High-Precision Metal Strip Winding Machine" (Patent Publication No.: CN206692051U, Patent Publication Date: 2017-12-01), the machine includes a housing and a main shaft. The housing is mainly composed of a cover, a support, and a base. The rear section of the main shaft is supported on the support, and the front section of the main shaft is fitted with a tensioning sleeve. A detection mechanism is provided on the outside of the tensioning sleeve for online detection of the width of the metal strip on the tensioning sleeve. The detection mechanism includes a lead screw parallel to the axis of the main shaft, a scale on the lead screw, and a rocker wheel installed at the outer end of the lead screw. The scale can slide back and forth along the axis of the lead screw to complete the detection. The support is supported on the base through a ball linear guide pair. A push cylinder is fixedly installed at the rear end of the base. The front end of the push rod of the push cylinder cooperates with the support. The support slides back and forth linearly relative to the base under the drive of the push cylinder. The testing agency is used to detect the width of the metal strip wound on the tensioning bushing in real time, ensuring that the width of the metal strip meets the production requirements, thereby improving the winding accuracy and production stability.

[0004] Based on the aforementioned existing technology, current single-axis high-speed winding mechanisms made from metal roll paper sleeves still have the following problems: in production lines with extremely fast production pace, frequent roll changes are unavoidable. Each roll change means that the entire production line must stop and wait, and the roll change operation is cumbersome and time-consuming, resulting in low production efficiency. Therefore, this utility model provides a single-axis high-speed winding mechanism made from metal roll paper sleeves. Utility Model Content

Detailed Implementation

[0023] 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.

[0024] Please see Figures 1-5 This utility model provides a technical solution:

[0025] A single-axis high-speed winding mechanism based on a metal roll paper sleeve includes a drive mechanism 1. A disassembly / assembly mechanism 2 is provided on the right side of the drive mechanism 1 for quick replacement of the winding drum. The disassembly / assembly mechanism 2 includes:

[0026] The inner support unit 21 is located on the right side of the drive mechanism 1. It includes a rotating shaft 211, on which a sliding sleeve 213 is slidably mounted. Three connecting seats 214 are mounted in a circumferential array on the surface of the sliding sleeve 213. Connecting rods 215 are rotatably mounted on both ends of the inner side of the sliding sleeve 213. A support seat 216 is rotatably mounted on one end of the connecting rod 215. The support seat 216 can be moved by sliding the sliding sleeve 213 in conjunction with the connecting rod 215, thereby achieving quick locking and quick disassembly of the winding drum.

[0027] The support unit 22 is located on the right side of the drive mechanism 1 and is used to support the inner support unit 21.

[0028] In this embodiment, a limiting disk 212 is fixedly installed on the surface of the rotating shaft 211, and three limiting grooves 2110 are opened in the inner circumferential array of the limiting disk 212. A limiting slide post 219 is fixedly installed on the left end of the support 216, and the limiting slide post 219 is located inside the limiting groove 2110 to adapt to sliding, so as to realize the limiting movement of the support 216.

[0029] By precisely guiding the sliding of the limiting slide 219 within the limiting groove 2110, the radial movement of the support 216 is strictly limited. This ensures that the three supports 216 can expand outward or contract inward synchronously, stably, and accurately, effectively preventing slippage or swaying of the winding drum during high-speed rotation, and greatly improving the reliability of clamping and the concentricity of winding.

[0030] In this embodiment, a threaded sleeve 217 is rotatably mounted on the right end surface of the rotating shaft 211, and the left side of the threaded sleeve 217 is rotatably connected to the sliding sleeve 213. A protruding rod 218 is fixedly mounted on the right end of the rotating shaft 211.

[0031] Rotating the threaded sleeve 217 drives the sliding sleeve 213 to move axially along the rotating shaft 211, thereby controlling the locking and unlocking of the support 216 through mechanical transmission. This provides an extremely simple, labor-saving, and efficient way to assemble and disassemble the winding drum, significantly shortening the downtime required to change the roll material. At the same time, the protruding rod 218 provides a reliable force support point for the subsequent support unit 22.

[0032] In this embodiment, the drive mechanism 1 includes a base frame 11, a bearing 14 is fixedly installed on the top of the upright of the base frame 11, a rotating shaft 211 rotates inside the bearing 14, a large sprocket 15 is fixedly installed on the left end of the rotating shaft 211, a motor 12 is fixedly installed on the top of the base frame 11, a small sprocket 13 is fixedly installed on the output end of the motor 12, and a chain 16 is installed between the small sprocket 13 and the large sprocket 15.

[0033] The motor 12 transmits power to the rotating shaft 211 efficiently and smoothly through the chain drive mechanism consisting of the small sprocket 13, the chain 16 and the large sprocket 15, providing ample and reliable torque for its high-speed rotation and ensuring the continuity and stability of the winding operation.

[0034] In this embodiment, the support unit 22 includes a rotating rod 221 rotatably installed inside the right end of the base frame 11. A support rod 222 is fixedly installed in the middle of the surface of the rotating rod 221. A protruding rod 218 is located inside the upper end of the support rod 222, and the support rod 222 supports the protruding rod 218 and the rotating shaft 211.

[0035] An additional movable and stable support point is provided at the right end of the shaft 211, which together with the bearing 14 at the left end forms a two-point support, greatly enhancing the system rigidity and bending strength of the shaft 211 and the entire inner support unit 21, effectively suppressing the vibration and deflection that may occur during high-speed winding, and ensuring the winding quality.

[0036] In this embodiment, a mounting base 224 is fixedly installed on the top right end of the base frame 11. A plug 225 is slidably installed inside the mounting base 224, and a baffle 226 is fixedly installed on the surface of the plug 225. A spring 227 is installed on the surface of the plug 225. A socket 223 is opened inside the support rod 222, and one end of the plug 225 is slidably inserted into the socket 223 to fix the position of the support rod 222.

[0037] When the support rod 222 is rotated to the working position and erected, the operator releases the insert 225. The elastic force of the spring 227 can automatically push the insert 225 into the insertion hole 223 of the support rod 222, locking it instantly. This design realizes the rapid and reliable fixing and release of the support unit 22 in the working state, further optimizing the operation process and improving efficiency.

[0038] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0039] During operation, firstly, the take-up drum is placed on the outside of the three support seats 216. The user rotates the threaded sleeve 217 to move the sliding sleeve 213 to the left. The sliding sleeve 213 drives the three support seats 216 to centrifugally expand outward through the connecting rod 215, thus fixing the take-up drum. When the support seats 216 move, the limiting slide pin 219 slides inside the limiting groove 2110, so that the support seats 216 are limited in movement.

[0040] Next, the user pulls the insert 225, causing the baffle 226 to compress the spring 227, and rotates the support rod 222 to drive the rotating rod 221 to rotate, so that the top of the support rod 222 supports the protruding rod 218. The user releases the insert 225, and the spring 227 pushes the baffle 226 with its own elastic force, at which time the insert 225 is inserted into the insertion hole 223 to fix the position of the support rod 222 on the insert 225.

[0041] Then, the motor 12 drives the small sprocket 13 to rotate, the small sprocket 13 drives the large sprocket 15 to rotate through the chain 16, the large sprocket 15 drives the rotating shaft 211 to rotate, and the rotating shaft 211 drives the inner support unit 21 to rotate as a whole to perform the winding operation.

[0042] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
