[0034] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0035] Reference Figures 1 to 7As shown, an embodiment of the present invention provides an automatic self-adhesive tape clamping roller, comprising: a mounting wall 100, a first rotating roller 200, a mounting column 300, three clamping plates 400, a limiting member 301, and an elastic member 302. The mounting wall 100 is welded from steel plates and structural steel. The mounting wall 100 provides mounting surfaces for other components. The mounting wall 100 is vertically positioned; the first rotating roller 200 is rotatably mounted on the mounting wall 100 via a bearing seat. The connection method between the first rotating roller 200 and the mounting wall 100 is prior art, and the specific structure of the bearing seat is also prior art, therefore it will not be described in detail. The first rotating roller 200 is perpendicular to the mounting wall 100; the first rotating roller 200 extends horizontally away from the mounting wall 100. The mounting column 300 is detachably connected to the first rotating roller 200, and is sleeved on the first rotating roller 200. The diameter of the mounting column 300 is larger than the diameter of the first rotating roller 200. The clamping plate 400 is slidably connected to the mounting post 300, which provides a mounting position for the clamping plate 400. Three clamping plates 400 are symmetrically arranged about the rotation axis of the first rotating roller 200. The clamping plates 400 can slide radially along the mounting post 300 and can move to a preset position within the sliding stroke of the clamping plate 400. The self-adhesive tape 500 is wound around the material cylinder 510. The specific structures of the self-adhesive tape 500 and the material cylinder 510 are existing technologies and will not be described in detail. When the clamping plate 400 is in the preset position, the side of the clamping plate 400 away from the mounting post 300 abuts against the inner wall of the material cylinder 510; the limiting member 301 is used to prevent the clamping plate 400 from disengaging from the mounting post 300; there are three corresponding elastic members 302, which are connected to the mounting post 300 and are used to drive the clamping plate 400 to move away from the mounting post 300 and drive the clamping plate 400 to abut against the inner wall of the material cylinder 510. When the cylinder 510 is not installed, the clamping plate 400 is pushed by the elastic element 302 to a position away from the mounting post 300, and the limiting element 301 restricts the travel of the clamping plate 400 away from the mounting post 300. When installing the cylinder 510, the clamping plate 400 is compressed by the cylinder 510 or manually pushed by the operator to bring it closer to the mounting post 300, automatically adapting to the inner diameter of the cylinder 510. After the cylinder 510 is installed in place, the elastic element 302 drives the clamping plate 400 to press tightly against the inner wall of the cylinder 510, forcing the cylinder 510 to automatically position itself on the central axis of the first rotating roller 200. The friction between the clamping plate 400 and the cylinder 510 is used to fix the cylinder 510. When installing the cylinder 510, simply push the cylinder 510 in, and the clamping plate 400 will automatically move inward when it contacts the inner wall of the cylinder 510, without the need for complicated operations or additional tools. When disassembling the material cylinder 510, simply overcome the elastic force and friction of the elastic element 302 to pull the material cylinder 510 outwards, and the clamping plate 400 will slide inwards along the inner wall of the material cylinder 510 to avoid it. This saves time when replacing the material cylinder 510 and improves production efficiency.

[0036] Reference Figures 1 to 3As shown, it can be understood that an anti-slip layer is provided on the side of the clamping plate 400 away from the mounting post 300. The anti-slip layer is made of rubber or silicone and is attached to the side of the clamping plate 400 away from the mounting post 300 with adhesive or double-sided tape. The anti-slip layer can significantly increase the coefficient of friction between the clamping plate 400 and the inner wall of the barrel 510. Under the same elastic force of the elastic element 302, it can provide stronger clamping friction, thereby enhancing the reliability of clamping the barrel 510. In addition, the fact that the anti-slip layer is made of a flexible material can also reduce wear on the inner wall of the barrel 510.

[0037] Reference Figures 1 to 3 As shown, it can be understood that the outer peripheral wall of the mounting post 300 is symmetrically provided with three sliding grooves 310. The sliding grooves 310 extend axially along the mounting post 300, providing radial movement limits for the intermediate plate 410 and the slider 420. Under the pushing of the elastic member 302 or the squeezing of the barrel 510, the clamping plate 400 can only move radially along the mounting post 300. On the side of the clamping plate 400 near the mounting post 300, there is an intermediate plate 410 extending into the corresponding sliding groove 310. At the end of the intermediate plate 410 away from the clamping plate 400, there is a slider 420. The limiting member 301 is disposed in the sliding groove 310. The size of the intermediate plate 410 is smaller than the size of the slider 420, and the limiting member 301 narrows the opening of the sliding groove 310. The opening of the sliding groove 310 only allows the intermediate plate 410 to pass through, not the other way around, so the limiting member 301 can limit the stroke of the slider 420. The limiting member 301 is integrally formed with the mounting post 300. A limiting member 301 is provided at the opening of the slide groove 310 to form a T-shape in the cross-section of the slide groove 310. The stroke of the slider 420 is limited by the bottom of the slide groove 310 and the limiting member 301. The limiting member 301 limits the maximum extension position of the clamping plate 400 when the material cylinder 510 is not installed, and the bottom of the slide groove 310 limits the maximum retracted position of the clamping plate 400 when the material cylinder 510 is installed. The slider 420, the intermediate plate 410, and the limiting member 301 are embedded inside the slide groove 310 without increasing the outer diameter of the mounting post 300, resulting in a compact structure. The slide groove 310 and the slider 420 can be made of polytetrafluoroethylene to reduce friction, making frequent replacement of the material cylinder 510 easier.

[0038] Reference Figures 3 to 6As shown, it can be understood that a positioning screw 311 is provided through the side wall of the slide groove 310. The positioning screw 311 is an internal hexagon set screw. The positioning screw 311 passes through the side wall of the slide groove 310 and extends into the slide groove 310. The positioning screw 311 limits the slider 420 in the direction parallel to the axis of the mounting post 300. The installation steps of the clamping plate 400 are as follows: tighten the positioning screw 311 until it is removed from the slide groove 310, slide the intermediate plate 410 and the slider 420 into the slide groove 310 from the length direction of the slide groove 310, and then tighten the positioning screw 311 into the slide groove 310 so that the positioning screw 311 blocks the slider 420. During disassembly, simply loosen the positioning screw 311 with an internal hexagon wrench to release the axial constraint of the slider 420, and the entire assembly of the clamping plate 400, intermediate plate 410 and slider 420 can be pulled out along the axial direction of the slide groove 310. It is foreseeable that the extension direction of the positioning screw 311 avoids the clamping plate 400 so that it will not be blocked by the clamping plate 400 when using a wrench.

[0039] Reference Figures 4 to 7 As shown, the elastic element 302 is a spring sheet, bolted to the bottom wall of the slide groove 310. As a flat elastic element, the spring sheet can easily fit into the narrow space at the bottom of the slide groove 310, saving radial space compared to a coil spring, resulting in a compact overall structure. The spring sheet deforms evenly under pressure, preventing the clamping plate 400 from jamming due to uneven force. When the elastic element 302 needs to be replaced, first remove the clamping plate 400, then loosen the bolts securing the spring sheet through the opening in the slide groove 310 to remove the spring sheet. The elastic element 302 abuts against the slider 420 to indirectly push the clamping plate 400.

[0040] Reference Figures 1 to 4 As shown, it can be understood that the first rotating roller 200 is threaded, and the rotation direction of the thread is opposite to the rotation direction of the first rotating roller 200, so as to achieve the technical effect of automatic locking. A tapered portion 600 is threadedly connected to the first rotating roller 200, and the tapered portion 600 is sleeved on the first rotating roller 200. The size of the tapered portion 600 gradually narrows towards the mounting wall 100, and the tapered portion 600 is used to push the clamping plate 400 tightly against the inner wall of the barrel 510. The inclined surface design of the tapered portion 600 converts the rotational force of the tapered portion 600 into the radial expansion force of the clamping plate 400, pushing the clamping plate 400 tightly against the inner wall of the barrel 510. When the elastic element 302 is at risk of failure due to long-term use, the clamping by the tapered portion 600 can play an auxiliary fixing role, avoiding the risk of aging of the elastic element 302. It is foreseeable that when the self-adhesive tape 500 and the barrel 510 have a small self-weight, the tapered portion 600 is not needed.

[0041] Reference Figures 1 to 6As shown, it can be understood that the cross-section of the end of the first rotating roller 200 furthest from the mounting wall 100 is a regular hexagon. To facilitate operation with an external hex wrench, when tightening the tapered part 600, an external hex wrench is needed to fix the first rotating roller 200 so that it cannot rotate. The operation is simple, and a single person can quickly complete the installation of the tapered part 600.

[0042] Reference Figures 1 to 6 As shown, it can be understood that the end of the clamping plate 400 away from the mounting wall 100 is provided with a guide plate 430 inclined towards the mounting column 300. When the barrel 510 is advanced along the axis, the inclined surface of the guide plate 430 contacts the end edge of the barrel 510 to play a guiding role. The axial thrust applied by the barrel 510 is decomposed into a component force that pushes the guide plate 430 to retract radially and a component force that slides the barrel 510 axially. The operator can complete the installation of the barrel 510 by directly pushing it forward with one hand.

[0043] Reference Figures 1 to 6 As shown, it can be understood that a baffle plate 320 is provided on the side of the mounting column 300 near the mounting wall 100, and the diameter of the baffle plate 320 is larger than the diameter of the mounting column 300. The baffle plate 320 is used to position the material cylinder 510. The operator only needs to continuously push the material cylinder 510 during the advancement process until the material cylinder 510 is blocked by the baffle plate 320.

[0044] Reference Figure 1 As shown, it can be understood that the mounting post 300 is bolted to the first rotating roller 200. The mounting post 300 has multiple mounting threaded holes extending radially along the mounting post 300, and hexagon socket set screws are threaded into the mounting threaded holes. The hexagon socket set screws abut against the first rotating roller 200 to fix the mounting post 300.

[0045] Usage steps: Observe whether the clamping plate 400 is pushed to the outermost side by the elastic element 302. Hold the material cylinder 510 and align its inner hole with the guide plate 430. Smoothly push the material cylinder 510 along the axis. The inclined surface of the guide plate 430 will automatically guide the material cylinder 510 to its correct position. The material cylinder 510 presses against the clamping plate 400, compresses the elastic element 302, and contracts radially until the end face of the material cylinder 510 abuts against the retaining plate 320. Use a hex wrench to fix the first rotating roller 200 and tighten the conical part 600 to complete the installation.

[0046] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
