Description

Technical Field

[0001] This utility model relates to the field of self-adhesive tape technology, and in particular to an automatic self-adhesive tape splicing device. Background Technology

[0002] In the production of self-adhesive tape, the tape is typically wound onto a spool. Once a roll of tape is used up, it needs to be replaced with a new one. Current technology requires stopping the production line during this roll change. After shutdown, operators unload the empty spool, install a new spool, and manually pull the tape to the next process. This time-consuming process leads to reduced production efficiency. While the self-adhesive property of the tape simplifies splicing, manual operation still makes it difficult to maintain production line continuity and meet the demands of continuous production. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes an automatic self-adhesive tape splicing device, which can significantly improve production efficiency.

[0004] An automatic self-adhesive tape splicing device according to a first aspect of the present invention includes: a mounting wall, a rotating disk, a first clamping mechanism, a second clamping mechanism, a pulling mechanism, and a redirecting roller. The mounting wall is vertically arranged, and a switching motor is installed on the mounting wall. The rotating disk is rotatably mounted on the mounting wall, and the switching motor drives the rotating disk to rotate. The rotating disk has a first position and a second position. A first clamping mechanism is rotatably mounted on the rotating disk. The self-adhesive tape is wound around a material cylinder, and the first clamping mechanism is used to fix the self-adhesive tape and the material cylinder. A second clamping mechanism is rotatably mounted on the rotating disk, and the second clamping mechanism is used to fix the self-adhesive tape and the material cylinder. The rotation axes of the second clamping mechanism, the first clamping mechanism, and the rotating disk are parallel to each other. A pulling mechanism is used to pull the self-adhesive tape wound around the material cylinder and transport it to the next process. A redirecting roller is arranged between the pulling mechanism and the material cylinder to change the movement direction of the self-adhesive tape. When the rotating disk is in the first position, the first clamping mechanism is located between the second clamping mechanism and the redirecting roller. When the rotating disk is in the second position, the second clamping mechanism is located between the first clamping mechanism and the redirecting roller.

[0005] An automatic self-adhesive tape reeling device according to an embodiment of the present invention has at least the following beneficial effects: When the rotating disk is in the first position, a material cylinder is fixed on the first clamping mechanism. The pulling mechanism drives the self-adhesive tape wound on the material cylinder through the redirecting roller and then conveys it to the next process. When the self-adhesive tape wound on the material cylinder is about to run out, the rotating disk first switches to the second position. Then, the operator installs a full roll of self-adhesive tape on the second clamping mechanism. Since the second clamping mechanism is located between the first clamping mechanism and the redirecting roller when the rotating disk is in the second position, after the self-adhesive tape on the first clamping mechanism is used up, the end of the self-adhesive tape will pass through the second clamping mechanism. At this time, the operator sticks the starting end of the self-adhesive tape on the second clamping mechanism to the end of the self-adhesive tape driven by the pulling mechanism. The pulling mechanism then drives the full roll of self-adhesive tape on the second clamping mechanism to continue transporting it to the next process. When the self-adhesive tape on the second clamping mechanism is almost used up, switch the rotary table to the first position. Then, the operator loads a full roll of self-adhesive tape onto the first clamping mechanism. Since the first clamping mechanism is located between the second clamping mechanism and the redirecting roller when the rotary table is in the first position, the end of the self-adhesive tape on the second clamping mechanism will pass through the first clamping mechanism after the tape is used up. At this point, the operator attaches the starting end of the self-adhesive tape on the first clamping mechanism to the end of the self-adhesive tape being pulled by the pulling mechanism. The pulling mechanism will then continue to transport the full roll of self-adhesive tape on the first clamping mechanism to the next process. Repeating the above steps will automatically adhere the self-adhesive tape, allowing it to be continuously transported to the next process. This significantly improves production efficiency, reduces downtime, and lowers the intensity of manual intervention.

The multiple clamping plates are symmetrically arranged about the rotation axis of the first rotating roller. The clamping plates can slide radially along the mounting column. The side of the clamping plate away from the mounting column abuts against the inner wall of the material cylinder. A limiting member is connected to the mounting column to prevent the clamping plate from detaching from the mounting column.

[0042] Reference Figures 1 to 12As shown, an embodiment of the present invention provides an automatic self-adhesive tape splicing device, comprising: a mounting wall 100, a rotating disk 300, a first clamping mechanism 400, a second clamping mechanism 500, a pulling mechanism 700, and a redirecting roller 800. The mounting wall 100 is vertically arranged and is welded from steel plates and structural steel, providing a mounting surface for other components. A switching motor 200 is mounted on the mounting wall 100. The rotating disk 300 is disc-shaped and rotatably mounted on the mounting wall 100, with its rotation axis perpendicular to the mounting wall 100. The switching motor 200 drives the rotating disk 300 to rotate, and a stepper motor is selected to precisely control the rotation angle of the rotating disk 300. The rotating disk 300 has a first position and a second position; the switching motor 200 can drive the rotating disk 300 to switch between the first and second positions. The rotating disk 300 rotates 180 degrees from the first position to switch to the second position. The first clamping mechanism 400 is rotatably mounted on the rotating disk 300. The self-adhesive tape 600 is wound around the material cylinder 610. The specific structures of the self-adhesive tape 600 and the material cylinder 610 are existing technologies and will not be described in detail. The first clamping mechanism 400 and the second clamping mechanism 500 have the same structure. The first clamping mechanism 400 is used to fix the self-adhesive tape 600 and the material cylinder 610. After being fixed on the first clamping mechanism 400, the material cylinder 610 can rotate, but cannot move along the axial direction of the material cylinder 610. The second clamping mechanism 500 is rotatably mounted on the rotating disk 300. The second clamping mechanism 500 is used to fix the self-adhesive tape 600 and the material cylinder 610. After being fixed on the second clamping mechanism 500, the material cylinder 610 can rotate, but cannot move along the axial direction of the material cylinder 610. The rotation axes of the second clamping mechanism 500, the first clamping mechanism 400, and the rotating disk 300 are parallel to each other. The pulling mechanism 700 is used to pull and transport the self-adhesive tape 600 wound on the material cylinder 610 to the next process. The specific structure of the pulling mechanism 700 is prior art and will not be described in detail. The redirecting roller 800 is disposed between the pulling mechanism 700 and the material cylinder 610 to change the movement direction of the self-adhesive tape 600. The specific structure of the redirecting roller 800 is prior art and will not be described in detail. When the rotating disk 300 is in the first position, the first clamping mechanism 400 is located between the second clamping mechanism 500 and the redirecting roller 800. When the rotating disk 300 is in the second position, the second clamping mechanism 500 is located between the first clamping mechanism 400 and the redirecting roller 800. The rotating disk 300 is in the first position, the material cylinder 610 is fixed on the first clamping mechanism 400, and the pulling mechanism 700 drives the self-adhesive tape 600 wound on the material cylinder 610 through the redirecting roller 800 and then conveys it to the next process.When the self-adhesive tape 600 wound on the material cylinder 610 is about to run out, the rotating disk 300 first switches to the second position, and then the operator installs a full roll of self-adhesive tape 600 on the second clamping mechanism 500. Since the second clamping mechanism 500 is located between the first clamping mechanism 400 and the redirecting roller 800 when the rotating disk 300 is in the second position, after the self-adhesive tape 600 on the first clamping mechanism 400 is used up, the end of the self-adhesive tape 600 will pass through the second clamping mechanism 500. At this time, the operator sticks the starting end of the self-adhesive tape 600 on the second clamping mechanism 500 to the end of the self-adhesive tape 600 driven by the pulling mechanism 700. The pulling mechanism 700 will then drive the full roll of self-adhesive tape 600 on the second clamping mechanism 500 to continue to transport to the next process. When the self-adhesive tape 600 on the second clamping mechanism 500 is almost used up, the rotating disk 300 is switched to the first position. Then, the operator loads a full roll of self-adhesive tape 600 onto the first clamping mechanism 400. Since the first clamping mechanism 400 is located between the second clamping mechanism 500 and the redirecting roller 800 when the rotating disk 300 is in the first position, the end of the self-adhesive tape 600 on the second clamping mechanism 500 will pass through the first clamping mechanism 400 after the self-adhesive tape 600 on the second clamping mechanism 500 is used up. At this time, the operator attaches the starting end of the self-adhesive tape 600 on the first clamping mechanism 400 to the end of the self-adhesive tape 600 driven by the pulling mechanism 700. The pulling mechanism 700 will then drive the full roll of self-adhesive tape 600 on the first clamping mechanism 400 to continue transporting it to the next process. Repeating the above steps will automatically adhere the self-adhesive tape 600, allowing it to be continuously transported to the next process. The operator's main task is simply to install the full roll of tape 610 on the spare clamping mechanism and perform the pasting operation when the ends of the new and old self-adhesive tape 600 meet. By switching the rotary table 300 between the first and second positions, and by alternating between the first clamping mechanism 400 and the second clamping mechanism 500, the operator ensures that when a roll of self-adhesive tape 600 is about to run out, the position can be automatically switched, and the pulling mechanism 700 can continue to pull a new roll of self-adhesive tape 600 without stopping. This significantly improves production efficiency, reduces downtime, and reduces the intensity of manual intervention.

[0043] Reference Figure 3 and Figure 4 As shown, it can be understood that a switching bearing seat 110 is provided on the side of the mounting wall 100 away from the first clamping mechanism 400. A rotating shaft 310 is connected to the rotating disk 300, passing through the mounting wall 100 and rotatably connected to the mounting wall 100 via the switching bearing seat 110. The switching bearing seat 110 prevents excessive deformation or vibration of the rotating disk 300 during rotation or under load. It is foreseeable that a deep groove ball bearing is installed inside the switching bearing seat 110, which reduces the friction of the rotating disk 300 during rotation. This improves the overall stability and reliability of the equipment and reduces the failure rate.

[0044] Reference Figure 3 and Figure 4 As shown, it can be understood that the end of the rotating shaft 310 away from the rotating disk 300 extends out of the switching bearing housing 110, and a driven gear 311 is provided at the end of the rotating shaft 310 away from the rotating disk 300. The output end of the switching motor 200 is connected to the driving gear 210, and the driving gear 210 meshes with the driven gear 311. With proper lubrication and maintenance, the gear pair can work stably for a long time. The torque generated by the switching motor 200 is transmitted to the rotating shaft 310 through the driving gear 210 and the driven gear 311, thereby driving the rotating shaft 310 to rotate.

[0045] Reference Figure 3 and Figure 4 As shown, it can be understood that the diameter of the driving gear 210 is smaller than the diameter of the driven gear 311. The rotating disk 300 is relatively heavy, resulting in high inertia and requiring significant torque for starting, stopping, and accurate positioning. However, stepper motors typically output relatively low torque at high speeds. Therefore, by using a suitable gear ratio, the output torque of the switching motor 200 is amplified, reducing the final speed of the rotating disk 300 and making its rotation smoother.

[0046] Reference Figures 5 to 10As shown, the first clamping mechanism 400 includes a first rotating roller 410, a mounting post 420, and three clamping plates 430. The first rotating roller 410 is rotatably mounted on the rotating disk 300. The connection method between the first rotating roller 410 and the mounting wall 100 is existing technology and will not be described in detail. The first rotating roller 410 is perpendicular to the mounting wall 100. The mounting post 420 is bolted to the first rotating roller 410 and is sleeved on the first rotating roller 410. The diameter of the mounting post 420 is larger than the diameter of the first rotating roller 410. The clamping plate 430 is slidably connected to the mounting post 420. The three clamping plates 430 are symmetrically arranged around the rotation axis of the first rotating roller 410. The first rotating roller 410 extends horizontally away from the mounting wall 100. The clamping plate 430 can slide radially along the mounting post 420. The clamping plate 430 can move to a preset position within the sliding stroke of the clamping plate 430. The mounting post 420 provides a mounting position for the clamping plate 430. When the clamping plate 430 is in the preset position, the side of the clamping plate 430 away from the mounting post 420 abuts against the inner wall of the material cylinder 610. A limiting member 421 is connected to the mounting column 420. The limiting member 421 is used to prevent the clamping plate 430 from detaching from the mounting column 420. An elastic member 422 is connected to the mounting column 420. There are three corresponding elastic members 422. The elastic members 422 are connected to the mounting column 420. The elastic members 422 are used to drive the clamping plate 430 to move away from the mounting column 420 and drive the clamping plate 430 to press tightly against the inner wall of the material cylinder 610. When the barrel 610 is not installed, the clamping plate 430 is pushed by the elastic element 422 to a position away from the mounting post 420, and the limiting element 421 restricts the travel of the clamping plate 430 away from the mounting post 420. When installing the barrel 610, the clamping plate 430 is pushed by the barrel 610 or manually by the operator to compress the elastic element 422 and move closer to the mounting post 420, automatically adapting to the inner diameter of the barrel 610. After the barrel 610 is installed in place, the elastic element 422 drives the clamping plate 430 to press tightly against the inner wall of the barrel 610, forcing the barrel 610 to automatically position itself on the central axis of the first rotating roller 410. The friction between the clamping plate 430 and the barrel 610 is used to fix the barrel 610. When installing the barrel 610, simply push the barrel 610 in, and the clamping plate 430 will automatically move inward when it contacts the inner wall of the barrel 610, without the need for complicated operations or additional tools. When disassembling the material cylinder 610, simply overcome the elastic force and friction of the elastic element 422 to pull the material cylinder 610 outwards, and the clamping plate 430 will slide inwards along the inner wall of the material cylinder 610 to avoid it. This saves time when replacing the material cylinder 610 and improves production efficiency.

[0047] Reference Figures 5 to 10As shown, it can be understood that an anti-slip layer is provided on the side of the clamping plate 430 away from the mounting post 420. The anti-slip layer is made of rubber or silicone and is attached to the side of the clamping plate 430 away from the mounting post 420 with adhesive or double-sided tape. The anti-slip layer significantly increases the coefficient of friction between the clamping plate 430 and the inner wall of the barrel 610. Under the same elastic force of the elastic element 422, it can provide stronger clamping friction, enhancing the reliability of clamping the barrel 610. 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 610.

[0048] Reference Figures 5 to 10 As shown, it can be understood that three sliding grooves 423 are symmetrically arranged on the outer peripheral wall of the mounting post 420. The sliding grooves 423 extend axially along the mounting post 420, providing radial movement limits for the intermediate plate 431 and the slider 432. Under the pushing of the elastic member 422 or the extrusion of the barrel 610, the clamping plate 430 can only move radially along the mounting post 420. An intermediate plate 431 extending into the corresponding sliding groove 423 is provided on the side of the clamping plate 430 near the mounting post 420. A slider 432 is provided at the end of the intermediate plate 431 away from the clamping plate 430. The limiting member 421 is disposed in the sliding groove 423. The size of the intermediate plate 431 is smaller than the size of the slider 432, and the limiting member 421 narrows the opening of the sliding groove 423. The opening of the sliding groove 423 only allows the intermediate plate 431 to pass through, not the other way around, so the limiting member 421 can limit the stroke of the slider 432. The limiting member 421 is integrally formed with the mounting post 420. The opening of the slide groove 423 is equipped with a limiting member 421 to form a T-shape in the cross-section of the slide groove 423. The stroke of the slider 432 is limited by the bottom of the slide groove 423 and the limiting member 421. The limiting member 421 limits the maximum extension position of the clamping plate 430 when the material cylinder 610 is not installed, and the bottom of the slide groove 423 limits the maximum retracted position of the clamping plate 430 when the material cylinder 610 is installed. The slider 432, the intermediate plate 431, and the limiting member 421 are embedded inside the slide groove 423 without increasing the outer diameter of the mounting post 420, resulting in a compact structure.

[0049] Reference Figures 5 to 10As shown, it can be understood that a positioning screw 424 is provided through the side wall of the slide groove 423. The positioning screw 424 is an internal hexagon set screw. The positioning screw 424 passes through the side wall of the slide groove 423 and extends into the slide groove 423. The positioning screw 424 limits the slider 432 in the direction parallel to the axis of the mounting post 420. The installation steps of the clamping plate 430 are as follows: tighten the positioning screw 424 until it is removed from the slide groove 423, slide the intermediate plate 431 and the slider 432 into the slide groove 423 from the length direction of the slide groove 423, and then tighten the positioning screw 424 into the slide groove 423 so that the positioning screw 424 blocks the slider 432. During disassembly, simply loosen the positioning screw 424 with an internal hexagon wrench to release the axial constraint of the slider 432, and the entire assembly of the clamping plate 430, the intermediate plate 431 and the slider 432 can be pulled out along the axial direction of the slide groove 423. It is foreseeable that the extension direction of the positioning screw 424 avoids the clamping plate 430 so that it will not be blocked by the clamping plate 430 when using a wrench.

[0050] Reference Figures 5 to 10 As shown, the elastic element 422 is a spring sheet, which is bolted to the bottom wall of the slide groove 423. As a flat elastic element, the spring sheet can easily fit into the narrow space at the bottom of the slide groove 423, saving radial space compared to a coil spring, resulting in a compact overall structure. The spring sheet deforms evenly under pressure, preventing the retaining plate 430 from jamming due to uneven force. When the elastic element 422 needs to be replaced, first remove the retaining plate 430, then loosen the bolts securing the spring sheet through the opening in the slide groove 423 to remove the spring sheet. The elastic element 422 abuts against the slider 432 to indirectly push the retaining plate 430.

[0051] Reference Figures 5 to 10 As shown, it can be understood that the end of the clamping plate 430 away from the mounting wall 100 is provided with a guide plate 433 inclined towards the mounting post 420. When the barrel 610 is advanced along the axis, the inclined surface of the guide plate 433 contacts the end edge of the barrel 610 to play a guiding role. The axial thrust applied by the barrel 610 is decomposed into a component force that pushes the guide plate 433 to retract radially and a component force that slides the barrel 610 axially. The operator can complete the installation of the barrel 610 by directly pushing it forward with one hand.

[0052] Operating steps: When starting work, the rotating disk 300 is in the first position, and the material cylinder 610 filled with self-adhesive tape 600 is fixed on the first clamping mechanism 400. The pulling mechanism 700 drives the self-adhesive tape 600 wound on the material cylinder 610 through the redirecting roller 800 and then conveys it to the next process. When the self-adhesive tape 600 wound on the material cylinder 610 is about to run out, the rotating disk 300 first switches to the second position, and then the operator installs a full roll of self-adhesive tape 600 on the second clamping mechanism 500. Since the second clamping mechanism 500 is located between the first clamping mechanism 400 and the redirecting roller 800 when the rotating disk 300 is in the second position, after the self-adhesive tape 600 on the first clamping mechanism 400 is used up, the end of the self-adhesive tape 600 will pass through the second clamping mechanism 500. At this time, the operator sticks the starting end of the self-adhesive tape 600 on the second clamping mechanism 500 to the end of the self-adhesive tape 600 driven by the pulling mechanism 700. The pulling mechanism 700 will then drive the full roll of self-adhesive tape 600 on the second clamping mechanism 500 to continue to transport to the next process. When the self-adhesive tape 600 on the second clamping mechanism 500 is almost used up, the rotating disk 300 is switched to the first position. Then, the operator installs a full roll of self-adhesive tape 600 on the first clamping mechanism 400. Since the first clamping mechanism 400 is located between the second clamping mechanism 500 and the redirecting roller 800 when the rotating disk 300 is in the first position, the end of the self-adhesive tape 600 on the second clamping mechanism 500 will pass through the first clamping mechanism 400 after the self-adhesive tape 600 on the second clamping mechanism 500 is used up. At this time, the operator sticks the starting end of the self-adhesive tape 600 on the first clamping mechanism 400 to the end of the self-adhesive tape 600 driven by the pulling mechanism 700. The pulling mechanism 700 will then drive the full roll of self-adhesive tape 600 on the first clamping mechanism 400 to continue to transport to the next process.

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.
