Description

Technical Field

[0001] The present application belongs to the field of winding equipment, and more specifically, to a winding structure with an automatic stop-retraction function. Background Art

[0002] In the textile, packaging, printing, coating and other industries, the winding equipment is an important part of the production line. It is responsible for winding and collecting the produced materials according to certain specifications. However, in the daily operation of the winding equipment, a common and tedious step is to replace the winding shaft. When the material on the winding shaft is full, it is necessary to stop the machine and manually replace the winding shaft.

[0003] In traditional winding equipment, when the operator starts to replace the winding shaft, the equipment often cannot automatically stop retreating, that is, when the operator cuts off the current material roll from the subsequent material, the end of the subsequent material that has not been wound up can easily retreat and slide down under its own tension. In this case, the operator needs to re-pass the material through each guide roller. This not only increases the labor intensity of the operator, but also reduces the efficiency of the production line. Therefore, it is necessary to solve the above technical problems. Summary of the invention

[0004] The purpose of the embodiments of the present application is to provide a winding structure with an automatic stop-retraction function to solve the technical problem in the prior art that the winding structure cannot automatically stop retraction.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted in the present application is to provide a winding structure with an automatic stop function, comprising:

[0006] frame;

[0007] A reel, rotatably mounted on the frame and used for reeling;

[0008] The backstop assembly includes a stand connected to the frame, and a pressure roller and a pressure roller rotatably mounted on the stand through one-way bearings, the outer circumferential surfaces of the pressure roller and the pressure roller abut against each other and are respectively parallel to the winding shaft, and the one-way bearings mounted on the pressure roller and the pressure roller have opposite locking directions so that the side of the pressure roller and the pressure roller that abut against each other can only rotate toward the winding shaft.

[0009] Optionally, a slide groove extending toward the pressure roller is provided on the stand, and the backstop assembly further comprises a sliding seat slidably connected to the slide groove and capable of being guided by the slide groove for movement;

[0010] The pressure roller is rotatably mounted on the sliding seat and can be driven by the sliding seat to approach or move away from the pressure roller.

[0011] Optionally, the back-stop assembly further comprises a spring connected to the sliding seat and used for always pressing the pressure roller tightly against the pressure-bearing roller.

[0012] Optionally, the backstop assembly further comprises a pressing plate detachably connected to the stand;

[0013] Two ends of the spring along its own deformation direction abut against the pressing plate and the sliding seat respectively.

[0014] Optionally, the backstop assembly further comprises an adjusting bolt threadedly connected to the pressure plate;

[0015] The adjusting bolt passes through the pressing plate and is used to abut against the sliding seat. The axial direction of the adjusting bolt is parallel to the sliding direction of the sliding seat relative to the sliding groove.

[0016] Optionally, the back-stop assembly further comprises a support bar connected to the stand and a rotating rod rotatably mounted on the sliding seat and capable of rotating around its own central axis, wherein the rotating rod is parallel to the pressure roller;

[0017] The rotating rod passes through the sliding seat and overlaps the supporting bar. A notch is provided on the rotating rod at a position corresponding to the supporting bar so that the center of gravity of the rotating rod deviates from its own central axis. The shape of the notch is adapted to the supporting bar and enables the supporting bar to be embedded in the notch during the rotation of the rotating rod.

[0018] Optionally, the backstop assembly further includes a handle connected to the end of the rotating rod.

[0019] Optionally, the winding structure with automatic anti-retraction function further includes an auxiliary guide roller parallel to the winding shaft and used for carrying the coiled material;

[0020] The auxiliary guide roller and the winding shaft are distributed on opposite sides of the back-stopping assembly.

[0021] Optionally, the auxiliary guide roller is transmission-connected with a driving motor capable of driving the auxiliary guide roller to rotate;

[0022] The rotation direction of the auxiliary guide roller is consistent with the rotation direction of the winding shaft.

[0023] Optionally, the anti-retraction assembly further includes a bottom plate connected to the stand, and the stand is connected to the frame via the bottom plate.

[0024] The winding structure with automatic anti-retraction function provided by the present application has the following beneficial effects: compared with the prior art, in the winding structure with automatic anti-retraction function of the present application, the winding shaft can be used for winding materials, and the one-way bearing mounted on the pressure roller and the pressure roller can make the side of the pressure roller and the pressure roller that are used to abut each other only able to rotate toward the winding shaft. In this way, when the material to be wound passes through between the pressure roller and the pressure roller and is wound onto the material winding shaft, the material can drive the pressure roller and the pressure roller to rotate freely, that is, the material can freely pass through the position between the pressure roller and the pressure roller; and when the material on the winding shaft is fully wound, the material between the winding shaft and the anti-retraction component can be cut off, because the pressure roller and the pressure roller cannot rotate in the opposite direction under the action of the one-way bearing, so the material between the two can be stably clamped and prevented from retreating, so that the material end can be wound onto another empty winding shaft conveniently, effectively solving various problems caused by the inability of the rolled material to automatically stop retreating and significantly improving the replacement efficiency of the winding shaft, which is far superior to the prior art.

[0035] Please also read Figures 1 to 4 Now, a winding structure with an automatic anti-retraction function provided in an embodiment of the present application is described. The winding structure with an automatic anti-retraction function comprises a frame 101, a winding shaft 102 and an anti-retraction component 200. Among them:

[0036] The winding shaft 102 is rotatably mounted on the frame 101 and is used for winding. The backstop assembly 200 includes a stand 201 connected to the frame 101 and a pressure roller 203 and a pressure roller 204 rotatably mounted on the stand 201 through a one-way bearing 202. The outer circumferential surfaces of the pressure roller 203 and the pressure roller 204 abut against each other and are respectively parallel to the winding shaft 102. The one-way bearing 202 mounted on the pressure roller 203 and the pressure roller 204 has opposite locking directions so that the side of the pressure roller 203 and the pressure roller 204 that abut against each other can only rotate toward the winding shaft 102.

[0037] According to the above structure provided in the present embodiment, in the winding structure with automatic anti-retraction function in the present embodiment, the winding shaft 102 can be used to wind up the material, and the one-way bearing 202 mounted on the pressure roller 203 and the pressure roller 204 can enable the pressure roller 203 and the pressure roller 204 to rotate only toward the winding shaft 102 on the side that abuts against each other. In this way, when the material to be rolled up passes between the pressure roller 203 and the pressure roller 204 and is wound onto the material receiving shaft, the material can drive the pressure roller 203 and the pressure roller 204 to rotate freely, that is, the material can freely pass through the position between the pressure roller 203 and the pressure roller 204; and when the material on the winding shaft 102 is full, the material between the winding shaft 102 and the stop assembly 200 can be cut off. Since the pressure roller 203 and the pressure roller 204 cannot rotate in opposite directions under the action of the one-way bearing 202, the material between the two can be stably clamped and prevented from retreating, making it convenient to wind the material end onto another empty winding shaft, effectively solving various problems caused by the inability of the rolled material to automatically stop retreating and significantly improving the replacement efficiency of the winding shaft 102, which is far superior to the prior art.

[0038] In another embodiment of the present application, please refer to Figures 1 to 4 , a slide groove 205 extending toward the pressure roller 204 is provided on the stand 201, and the backstop assembly 200 also includes a sliding seat 206 slidably connected to the slide groove 205 and capable of being provided with a moving guide by the slide groove 205, and the pressure roller 203 is rotatably mounted on the sliding seat 206 and can be driven by the sliding seat 206 to approach or move away from the pressure roller 204. According to the above structure provided in this embodiment, the pressure roller 203 is rotatably mounted on the sliding seat 206 so that the pressing force between the pressure roller 203 and the pressure roller 204 can be adjusted by moving the sliding seat 206 in the slide groove 205, so that the pressing force between the pressure roller 203 and the pressure roller 204 in this embodiment can be adapted to the winding of a variety of different materials, which is conducive to significantly expanding the application scenarios of the winding structure with automatic backstop function provided in this embodiment.

[0039] In another embodiment of the present application, please refer to Figures 1 to 4 The backstop assembly 200 further includes a spring 207 connected to the sliding seat 206 and used to always press the pressure roller 203 against the pressure roller 204. According to the above structure provided in this embodiment, the spring 207 can act on the sliding seat 206 to make the pressure roller 203 always press against the pressure roller 204 with a constant pressure, so as to maintain sufficient clamping force on the material when the backstop action occurs, which is conducive to significantly improving the operating stability of the winding structure with automatic backstop function provided in this embodiment.

[0040] In another embodiment of the present application, please refer to Figures 1 to 4The backstop assembly 200 further includes a pressing plate 208 detachably connected to the stand 201, and the two ends of the spring 207 along its own deformation direction respectively abut against the pressing plate 208 and the sliding seat 206. According to the above structure provided in this embodiment, since the pressing plate 208 is detachably connected to the stand 201 and the spring 207 is connected to the pressing plate 208, the spring 207 can be conveniently replaced by removing the pressing plate 208, which is conducive to making the pressing force between the pressure roller 203 and the pressure roller 204 in this embodiment better adapted to different materials and further improving the operation stability of the winding structure with automatic backstop function provided in this embodiment.

[0041] In another embodiment of the present application, please refer to Figures 1 to 4 The backstop assembly 200 further includes an adjusting bolt 209 threadedly connected to the pressing plate 208, the adjusting bolt 209 passes through the pressing plate 208 and is used to abut against the sliding seat 206, and the axial direction of the adjusting bolt 209 is parallel to the sliding direction of the sliding seat 206 relative to the slide groove 205. According to the above structure provided in this embodiment, the adjusting bolt 209 threadedly connected to the pressing plate 208 and passing through the pressing plate 208 can flexibly adjust the moving range of the sliding seat 206, which is conducive to further expanding the application scenarios of the winding structure with automatic backstop function provided in this embodiment.

[0042] In another embodiment of the present application, please refer to Figures 1 to 4 The backstop assembly 200 further includes a support bar 210 connected to the stand 201 and a rotating rod 211 rotatably mounted on the sliding seat 206 and capable of rotating around its own central axis, and the rotating rod 211 is parallel to the pressure roller 203. The rotating rod 211 passes through the sliding seat 206 and overlaps the support bar 210. A notch 212 is provided on the rotating rod 211 at a position corresponding to the support bar 210 so that the center of gravity of the rotating rod 211 deviates from its own central axis. The shape of the notch 212 is adapted to the support bar 210 and enables the support bar 210 to be embedded in the notch 212 during the rotation of the rotating rod 211.

[0043] According to the above structure provided in the present embodiment, when the rotating rod 211 rotates around its own central axis and the supporting strip 210 is embedded in the notch 212 on the rotating rod 211, the sliding seat 206 can move in the slide groove 205 under the elastic force of the spring 207 and enable the pressure roller 203 to abut against the pressure roller 204; and when the rotating rod 211 rotates to the side away from the notch 212 and abuts against the supporting strip 210, the sliding seat 206 can be moved in the direction away from the pressure roller 204 and a certain distance of gap can be formed between the pressure roller 203 and the pressure roller 204 to facilitate the rapid passage of the material to be rolled up, thereby significantly improving the winding efficiency of the winding structure with automatic stop function provided in the present embodiment, which is far superior to the prior art.
