Description

Technical Field

[0001] This utility model relates to the field of self-adhesive tape production technology, and in particular to a self-adhesive tape and film bonding device. Background Technology

[0002] Self-adhesive tapes suitable for the cable industry include semiconductor self-adhesive tapes and insulating self-adhesive tapes. The final product of the self-adhesive tape needs to be wound up. To prevent multiple layers of self-adhesive tape from sticking together after winding, the self-adhesive tape and film must be bonded together before winding. After a roll is wound up, the bonded self-adhesive tape and film (forming a composite tape) need to be cut to facilitate changing to a new roll for winding. However, after cutting, the composite tape tends to shrink back, causing misalignment between the unbonded self-adhesive tape and film, which affects the subsequent bonding quality, such as causing air bubbles. Therefore, there is an urgent need for a bonding device that can prevent the composite tape from shrinking back after cutting. 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 a self-adhesive tape and film bonding device, which can prevent the self-adhesive tape and film from shrinking back after being cut and bonded, thereby improving the bonding quality.

[0004] The self-adhesive tape and film bonding device according to an embodiment of the present invention includes:

[0005] The worktable has an infeed end for receiving self-adhesive tape and film;

[0006] A bonding mechanism, disposed on the worktable, is used to bond the self-adhesive tape and the film together to form a composite tape;

[0007] An anti-retraction mechanism is provided on the workbench and located on the side of the bonding mechanism away from the material receiving end. The anti-retraction mechanism includes two clamping parts, which are used for the combined belt to pass through. The two clamping parts can be relatively close or far apart, and when the two clamping parts are relatively close, they can clamp the combined belt.

[0008] The self-adhesive tape and film bonding device according to the embodiments of this utility model has at least the following beneficial effects:

[0009] In use, the self-adhesive tape and film are fed into the worktable from the inlet end. The tape and film then pass through the bonding mechanism, which bonds them together to form a composite tape. The two clamping parts are then moved apart and held in a certain position, creating a channel between them for the composite tape to pass through without obstructing its transport. The composite tape is then passed between the two clamping parts and guided onto a winding drum. Once one drum is wound, the two clamping parts move closer together to clamp the composite tape. The composite tape can then be cut on the side of the drum near the anti-retraction mechanism. Because the two clamping parts clamp the composite tape, retraction is prevented, thus preventing the unbonded self-adhesive tape and film from shrinking back, avoiding misalignment and improving the quality of subsequent bonding.

[0010] According to some embodiments of the present invention, the anti-retraction mechanism further includes:

[0011] A first mounting bracket is connected to the workbench, and the two clamping parts are slidably mounted on the first mounting bracket along a first direction;

[0012] Two sets of first elastic portions are respectively provided for the two clamping portions. The first elastic portions are used to apply an elastic force to the clamping portions in the first direction toward the other clamping portion.

[0013] According to some embodiments of the present invention, the first direction is parallel to the vertical direction, and the self-adhesive tape / film bonding device further includes:

[0014] Two leveling roller sets are respectively arranged on opposite sides of the anti-retraction mechanism to keep the combined belt between the two clamping parts horizontal.

[0015] According to some embodiments of the present invention, the two clamping parts are respectively provided with clamping plates on opposite sides, the clamping plates are arranged perpendicular to the first direction, and when the two clamping parts are close to each other, they contact the combined belt through the clamping plates.

[0016] According to some embodiments of the present invention, the two clamping parts are respectively provided with mounting posts on opposite sides, the mounting posts slide through the first mounting frame along the first direction, the first elastic part is configured as a first compression spring, the first compression spring is sleeved on the mounting post, and its two ends respectively abut against the first mounting frame and the clamping part.

[0017] According to some embodiments of the present invention, the self-adhesive tape and film bonding device further includes:

[0018] A top support is slidably mounted on the first mounting bracket along a second direction. During the sliding process, the top support has at least a first state and a second state. In the first state, the top support is inserted between the two clamping parts so that the two clamping parts can be offset from the combined belt in the first direction. In the second state, the top support is offset from the two clamping parts in the second direction.

[0019] A positioning structure is detachably disposed between the top support and the first mounting bracket to keep the top support in the first state;

[0020] The second direction is perpendicular to the first direction.

[0021] According to some embodiments of the present invention, the two clamping parts are respectively provided with first inclined surfaces on opposite sides, and the top support is provided with second inclined surfaces on opposite sides along the first direction. During the process of the top support moving from the second state to the first state, the second inclined surfaces on opposite sides of the top support can respectively abut against the first inclined surfaces of the two clamping parts, so that the two clamping parts move away from each other.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0043] In the description of this utility model, "multiple" refers to two or more. The use of "first" and "second" is for distinguishing technical features only and should not be construed as indicating or implying relative importance, or implicitly indicating the number of technical features or their sequential relationship.

[0044] 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.

[0045] Reference Figure 1 and Figure 2 As shown, an embodiment of the self-adhesive tape and film bonding device of the present invention includes: a worktable 100, a bonding mechanism 300, and an anti-retraction mechanism 400.

[0046] The workbench 100 has a receiving end for receiving self-adhesive tape 200 and film 201. In this embodiment, the receiving end is located on the left side of the workbench 100.

[0047] The bonding mechanism 300 is disposed on the worktable 100. The bonding mechanism 300 is used to bond the self-adhesive tape 200 and the film 201 together to form a composite tape 202. In this embodiment, as shown... Figure 1 As shown, the self-adhesive tape 200 is on top, and the film 201 is on the bottom.

[0048] The anti-retraction mechanism 400 is disposed on the workbench 100 and located on the side of the bonding mechanism 300 away from the material receiving end. The anti-retraction mechanism 400 includes two clamping parts 410. The two clamping parts 410 are used for the combined belt 202 to pass through. The two clamping parts 410 can be relatively close or far apart, and when the two clamping parts 410 are relatively close, they can clamp the combined belt 202.

[0049] In use, the self-adhesive tape and film bonding device of this utility model is operated by feeding the self-adhesive tape 200 and film 201 from the feed end of the worktable 100. The self-adhesive tape 200 and film 201 are then fed through the bonding mechanism 300, which bonds them together to form a combined tape 202. The two clamping parts 410 are then moved away from each other and held in a certain state. In this state, a channel is formed between the two clamping parts 410 for the combined tape 202 to pass through, and the two clamping parts 410 do not affect the transmission of the combined tape 202. The combined tape 202 is then passed between the two clamping parts 410, and the assembly is completed. The composite tape 202 is guided onto a winding drum (not shown). The drum winds the composite tape 202. After one drum is wound, the two clamping parts 410 are moved closer together to clamp the composite tape 202. Then, the composite tape 202 can be cut on the side of the anti-retraction mechanism 400 near the drum. Because the two clamping parts 410 clamp the composite tape 202, it prevents the composite tape 202 from retracting, thus preventing the unbonded self-adhesive tape 200 and film 201 from shrinking back, thereby avoiding misalignment between the unbonded self-adhesive tape 200 and film 201 and improving the quality of subsequent bonding. Obviously, once a new drum is installed, the two clamping parts 410 are moved away from each other to release the composite tape 202.

[0050] It should be noted that the two clamping parts 410 only clamp the combination tape 202 when it is necessary to cut the combination tape 202.

[0051] Reference Figure 1 As shown, in some embodiments of this utility model, a first guide roller 110 is rotatably provided at the feeding end of the worktable 100. The first guide roller 110 is used for the self-adhesive tape 200 to bypass and guide the self-adhesive tape 200 into the worktable 100.

[0052] Understandably, a feeding device (not shown) is provided upstream of the workbench 100 to feed the self-adhesive tape 200 to the workbench 100.

[0053] Reference Figure 1 As shown, in some embodiments of this utility model, a feeding roller 120 is provided on the lower side of the workbench 100, and a film 201 is wound on the feeding roller 120 for providing the film 201.

[0054] It is understandable that multiple second guide rollers 130 are rotatably arranged between the feeding roller 120 and the material receiving end of the worktable 100. The second guide rollers 130 are used to allow the film 201 to bypass and guide the film 201 into the worktable 100. This is a conventional technical means and will not be described in detail here.

[0055] Reference Figure 1As shown, in some embodiments of this utility model, the workbench 100 is rotatably provided with a plurality of tension rollers 140 between the bonding mechanism 300 and the anti-retraction mechanism 400. The tension rollers 140 are used to adjust the conveying direction of the combined belt 202 and to tension the combined belt 202. This is a conventional technical means and will not be described in detail here.

[0056] Reference Figure 1 As shown, in some embodiments of this utility model, the bonding mechanism 300 includes a second mounting frame 310, a movable frame 320, a pressure roller 330, and a second elastic part 340. The second mounting frame 310 is fixed on the worktable 100, and the movable frame 320 is vertically slidably mounted on the second mounting frame 310. Specifically, the second mounting frame 310 is provided with a guide post 311 to provide vertical sliding guidance for the movable frame 320, and the movable frame 320 is correspondingly provided with holes for the guide post 311 to pass through. The pressure roller 330 is rotatably mounted around its own axis. In the movable frame 320, the second elastic part 340 is configured as a second compression spring. The second compression spring is disposed between the second mounting frame 310 and the movable frame 320 and is sleeved on the guide post 311. It is used to apply a downward elastic force to the movable frame 320. The self-adhesive tape 200 and the film 201 pass over the underside of the pressure roller 330. Through the cooperation between the pressure roller 330 and the upper surface of the worktable 100, the self-adhesive tape 200 and the film 201 can be bonded together. The bonding mechanism 300 is also a conventional technical means, so it will not be described in detail here.

[0057] It is conceivable that the relative approach or distance between the two clamping parts 410 can be achieved through a power structure; of course, other forms can also be adopted.

[0058] For example, refer to Figure 1 and Figure 2 As shown, in some embodiments of this utility model, the anti-retraction mechanism 400 further includes a first mounting frame 420 and two sets of first elastic portions 430. The first mounting frame 420 is connected to the worktable 100 and is located on the side of the fitting mechanism 300 away from the discharge end of the worktable 100. Two clamping portions 410 are slidably mounted on the first mounting frame 420 along a first direction, and the two clamping portions 410 are arranged opposite to each other along the first direction. The two sets of first elastic portions 430 are respectively arranged corresponding to the two clamping portions 410, that is, one clamping portion 430 ≤ one clamping portion 410 ≤ one clamping portion 43 ... A set of first elastic parts 430 is provided for part 410. The first elastic parts 430 are used to apply an elastic force to the clamping part 410 in the first direction toward the other clamping part 410. That is, the two sets of first elastic parts 430 act on the opposite sides of the two clamping parts 410 respectively, so that the two clamping parts 410 can move relatively close to each other, thereby clamping the combined belt 202. Obviously, if the two clamping parts 410 are to move away from each other, a reaction force greater than the elastic force of the first elastic parts 430 can be applied to the clamping part 410.

[0059] Specifically, a support frame 150 is provided on the right side of the workbench 100, and the first mounting bracket 420 is mounted on the support frame 150.

[0060] Specifically, a set of first elastic portions 430 includes at least two first elastic portions 430, which are located on opposite sides of the clamping portion 410 along its length. In this embodiment, the length direction of the clamping portion 410 is parallel to the width direction of the combined belt 202.

[0061] Reference Figure 1 and Figure 2 As shown, in some embodiments of this utility model, the first direction is parallel to the vertical direction. The self-adhesive tape and film bonding device also includes two leveling roller groups 500. The two leveling roller groups 500 are respectively disposed on opposite sides of the anti-retraction mechanism 400. The two leveling roller groups 500 are used to keep the combined tape 202 between the two clamping parts 410 horizontal. With this arrangement, when it is necessary to clamp the combined tape 202, the rollers are inclined relative to the combined tape 202. This embodiment can facilitate the two clamping parts 410 to clamp the combined tape 202.

[0062] Specifically, refer to Figure 1 As shown, two leveling roller sets 500 are respectively disposed on opposite sides of the anti-retraction mechanism 400 along the length direction of the combined belt 202. The leveling roller set 500 includes a third mounting frame 510 and two leveling rollers 520. The third mounting frame 510 is fixed on the support frame 150, and the leveling rollers 520 are rotatably disposed on the third mounting frame 510. The two leveling rollers 520 are vertically spaced apart, and the combined belt 202 passes between the two leveling rollers 520.

[0063] Reference Figure 2 and Figure 4 As shown, in some embodiments of this utility model, two clamping parts 410 are respectively provided with clamping plates 411 on opposite sides. The clamping plates 411 are arranged perpendicular to the first direction (i.e., horizontally). When the two clamping parts 410 are close to each other, they contact the combined belt 202 through the clamping plates 411. By providing the clamping plates 411, the contact area with the combined belt 202 can be increased when the two clamping parts 410 are used to clamp the combined belt 202, which can effectively prevent creases from forming on the combined belt 202.

[0064] Reference Figure 2 , Figure 4 and Figure 6As shown, in some embodiments of this utility model, two clamping parts 410 are respectively provided with mounting posts 412 on opposite sides. The mounting posts 412 slide through the first mounting frame 420 along the first direction. The first mounting frame 420 is provided with corresponding holes for the mounting posts 412 to pass through. The first elastic part 430 is set as a first compression spring. The first compression spring is sleeved on the mounting post 412 and its two ends abut against the first mounting frame 420 and the clamping part 410 respectively, thereby applying an elastic force to the clamping part 410. The structure is simple and stable.

[0065] Specifically, the mounting post 412 is fixed on the clamping plate 411, and the two ends of the first compression spring abut against the first mounting bracket 420 and the clamping plate 411 respectively. The clamping plate 411 has mounting posts 412 at both ends along its length and corresponding first compression springs.

[0066] It is understood that the first mounting bracket 420 may be composed of multiple brackets connected together, and its specific shape and composition may be designed according to the actual situation. This embodiment does not make specific limitations.

[0067] It is conceivable that during the normal transmission and winding of the combined tape 202, that is, before cutting, the two clamping parts 410 cannot clamp the combined tape 202 tightly. That is, sufficient distance needs to be maintained between the two clamping parts 410. To achieve this, a supporting component can be placed between the two clamping parts 410 to open up the two clamping parts 410 and ensure the stability of the two clamping parts 410.

[0068] For example, in some embodiments of this utility model, the self-adhesive tape and film bonding device further includes a top support 600 and a positioning structure; the top support 600 is slidably mounted on the first mounting bracket 420 along a second direction, the second direction being perpendicular to the first direction, and the top support 600 has at least a first state and a second state during the sliding process, in the first state (e.g. Figure 2 and Figure 4 As shown), the top support 600 is inserted between the two clamping parts 410 so that the two clamping parts 410 can be offset from the combined tape 202 (not shown in the figure) in the first direction to avoid affecting the normal transmission of the combined tape 202. In the second state (as shown in the figure), Figure 3 and Figure 5 As shown in the figure, the top support 600 and the two clamping parts 410 are offset in the second direction. In this state, the two clamping parts 410 can clamp the combined band 202 (not shown in the figure) under the action of the first elastic part 430. The positioning structure is detachably provided between the top support 600 and the first mounting bracket 420 to keep the top support 600 in the second state to ensure structural stability. When it is necessary to clamp the combined band 202 with the two clamping parts 410, the positioning structure can be removed and the top support 600 can be slid away from the clamping parts 410.

[0069] In this embodiment, the first direction is parallel to the vertical direction, the second direction is parallel to the left and right direction, and the width direction of the combined strip 202 is parallel to the front and back direction.

[0070] Reference Figure 2 , Figure 4 and Figure 5 As shown, in some embodiments of this utility model, two clamping parts 410 are respectively provided with first inclined surfaces 413 on opposite sides, and the inclination directions of the first inclined surfaces 413 of the two clamping parts 410 are opposite. The top support part 600 is provided with second inclined surfaces 601 on opposite sides along the first direction. The second inclined surfaces 601 match the first inclined surfaces 413. During the process of the top support part 600 moving from the second state to the first state, the second inclined surfaces 601 on opposite sides of the top support part 600 can respectively abut against the first inclined surfaces 413 of the two clamping parts 410, so that the two clamping parts 410 move away from each other.

[0071] In this embodiment, by setting the first inclined surface 413 and the second inclined surface 601, the cooperation between the two can enable the top support 600 to automatically insert between the two clamping parts 410 to open the two clamping parts 410 during the process of moving from the second state to the first state, which is very convenient to operate.

[0072] Reference Figure 4 As shown, in some embodiments of this utility model, the positioning structure includes a pin 700, a first positioning hole 602 extending in a first direction is provided on the top support 600, and a second positioning hole 421 extending in a first direction is provided on the first mounting bracket 420. In the first state, the pin 700 can be inserted into the first positioning hole 602 and the second positioning hole 421 to keep the top support 600 in the first state. The structure is simple and the pin 700 is easy to install and remove.

[0073] Reference Figure 4 As shown, in some embodiments of this utility model, a positioning step 603 is provided on the top support 600. When the first positioning hole 602 is aligned with the second positioning hole 421, the positioning step 603 abuts against the side of the first mounting bracket 420 away from the clamping part 410 in the second direction. In this way, the positioning step 603 can play a positioning indication function, making it convenient for the operator to quickly slide the top support 600 to the first state.

[0074] Reference Figure 5 As shown, in some embodiments of this utility model, a suspension ring 422 is provided on the first mounting bracket 420, and a hanging ring 701 is provided on the pin 700. A suspension rope 702 is connected between the suspension ring 422 and the hanging ring 701. Thus, when it is necessary to adjust the top support 600 to the second state, after removing the pin 700, it can be suspended on the first mounting bracket 420 by the suspension rope 702 to avoid loss.

[0075] In some specific embodiments, refer to Figure 4 and Figure 6 As shown, the top support 600 includes a top support seat 610 and a connecting rod 620 that are fixedly connected. The second inclined surface 601 is provided on the top support seat 610, and the connecting rod 620 is slidably passed through the first mounting bracket 420. The positioning step 603 and the first positioning hole 602 are both provided on the connecting rod 620.
