Description

Technical Field

[0001] The present invention relates to the technical field of cutting tools, in particular to a tape cutting device. Background Art

[0002] Double-sided tape is a crucial connection method for automotive exterior parts and is widely used on a variety of automotive exterior trims, such as various trim strips. Parts suppliers often apply the double-sided tape to the trim strips before supplying the entire assembly to the OEM. Therefore, applying double-sided tape is an essential process within the manufacturing plant. Workers are required to clean the back of the trim strips, apply a primer, cut the tape to the desired length and shape, and then bond the strips together, maintaining pressure with rollers.

[0003] Due to the diverse styling of vehicles, OEMs often have varying requirements for the shape of trim strips. Consequently, the width, length, and shape of the double-sided tape used to bond these trim strips can vary. For trim strip manufacturers, applying the double-sided tape can often become a bottleneck on the assembly line, requiring numerous workers to manually cut and apply the tape to ensure smooth operation.

[0004] In the existing double-sided tape application process, factories often purchase rolls of double-sided tape and have workers manually cut them during application. This results in extremely low efficiency, failing to meet the factory's cycle time and production capacity requirements. Furthermore, due to manual cutting, the tape length tolerance is very large, often leading to customer complaints. Furthermore, after applying the tape, workers need to use an auxiliary peeling head to ensure that customers can easily remove the release paper from the tape. Summary of the Invention

[0005] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a tape cutting device with high cutting efficiency and high cutting precision, and which can reserve a section of release paper as a stripping aid.

[0006] The present invention solves the technical problem by adopting a technical solution of providing a tape cutting device, wherein the tape comprises an adhesive strip and a release paper covering the adhesive strip, and the release paper can be torn off from the adhesive strip. The tape cutting device comprises:

[0007] a base, wherein the base is provided with a supporting structure for supporting the adhesive tape;

[0008] The cutting tool comprises a driving handle, a first cutting blade, a second cutting blade, and a third cutting blade, wherein one end of the driving handle is hinged to the base, and the other end of the driving handle is a free end; the first cutting blade, the second cutting blade, and the third cutting blade are sequentially arranged on the driving handle, and a preset distance is provided between the first cutting blade and the second cutting blade;

[0009] When the cutting tool cuts the tape, the first cutter and the third cutter can cut off the adhesive strip and the release paper on the tape, and the second cutter can cut off the adhesive strip on the tape, leaving a preset distance of release paper between the first cutter and the second cutter to serve as a stripping aid for the tape.

[0010] Furthermore, an upward convex structure is provided on the base below the second cutter, and when the adhesive tape is laid flat on the base, the height of the adhesive strip is greater than or equal to the height of the upward convex structure;

[0011] When the cutting blade cuts the tape, the upward convex structure abuts against the second cutter to limit the second cutter.

[0012] Furthermore, the base is provided with an upward convex structure at both ends close to the second cutter. When the cutting tool cuts the tape, the two upward convex structures respectively abut against the two ends of the second cutter.

[0013] Furthermore, the installation position of the third cutter on the driving handle is adjustable to adjust the distance between the third cutter and the first cutter.

[0014] Furthermore, the driving handle is provided with an elongated groove along its length direction, and a fixing member passes through the elongated groove to fix the third cutter on the driving handle, and the fixing position of the fixing member can be adjusted along the elongated groove.

[0015] Furthermore, the base is provided with two positioning plates for positioning the adhesive tape, the two positioning plates are spaced apart, and the adhesive tape can pass through between the two positioning plates;

[0016] The distance between the two positioning plates is adjustable to position the adhesive tapes of different widths.

[0017] Furthermore, a limit block is provided on the base, and the limit block is rotatably arranged on the base and close to the third cutter;

[0018] The limiting block can be rotated to the bottom of the third cutter or the driving handle to limit the cutting tool; and the limiting block can be rotated away from the bottom of the third cutter or the driving handle.

[0019] Furthermore, the support structure includes a first bracket, a second bracket and a reel, the first bracket and the second bracket are arranged on the base at intervals, and the reel is rotatably arranged between the first bracket and the second bracket;

[0020] After the adhesive tape is wound into an adhesive tape roll, it can be sleeved on the reel.

[0021] Furthermore, the base has a third bracket and a fourth bracket arranged at intervals, and the end of the driving handle away from the free end is provided with two hinged arms, the two hinged arms are arranged at intervals, and one of the hinged arms is hinged to the third bracket, and the other hinged arm is hinged to the fourth bracket.

[0022] Furthermore, the first cutter, the second cutter and the third cutter are all detachably fixedly mounted on the driving handle, and the first cutter, the second cutter and the third cutter each comprise a cutter head and a blade detachably fixedly connected to the cutter head;

[0023] A V-shaped groove is provided on the base below the first cutter. When the cutting tool cuts the tape, the first cutter cuts into the V-shaped groove.

[0024] Compared with the prior art, the present invention has at least the following beneficial effects:

[0025] In the present invention, the cutting tool is rotatably mounted on a base and includes a first cutter, a second cutter, and a third cutter, which are sequentially mounted on a drive handle. When cutting the tape, the first and third cutters cut both ends of the tape, that is, both the adhesive strip and the release paper of the tape are severed. The spacing between the first and third cutters determines the length of the tape cut. Furthermore, a preset distance exists between the first and second cutters, and the second cutter only cuts the adhesive strip, not the release paper. After each cut, the release paper between the first and second cutters serves as a peeling aid, making it easier for customers to remove the release paper after attaching the tape to an automotive exterior trim. This means that the tape cutting device can cut the tape at the desired distance, and after cutting, a peeling aid is reserved, making it easier for customers to remove the release paper. This eliminates the need for an additional peeling aid, improving tape cutting efficiency and reducing costs. In addition, the installation position of the third cutter is adjustable, and the distance between the third cutter and the first cutter can be adjusted, so that tapes of different lengths can be cut. The distance between the two positioning plates is adjustable, which can be suitable for tapes of different widths. This cutting device can cut tapes of different lengths and widths.

[0037] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in this field can implement it. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0038] like Figure 1 As shown, the adhesive tape 3 of this embodiment includes an adhesive strip 31 and a release paper 30 covering the adhesive strip 31. The release paper 30 can be torn off from the adhesive strip 31. Specifically, when the adhesive tape 3 is applied to an automotive trim, one side of the adhesive strip 31 adheres to the automotive trim, while the other side of the adhesive strip 31 has the release paper 30. When the automotive trim is bonded to another location, the release paper 30 needs to be torn off, leaving both sides of the adhesive strip 31 connected to the automotive trim and other components, thereby bonding them together.

[0039] like Figure 2-Figure 3 As shown, the tape cutting device of this embodiment mainly includes: a base 1 and a cutting tool 2. The cutting tool 2 mainly includes a driving handle 20 and a first cutting knife 21, a second cutting knife 22 and a third cutting knife 23.

[0040] The base 1 is provided with a support structure for supporting the adhesive tape 3. Specifically, the main structure of the base 1 is a bottom plate. The support structure includes a first bracket 101, a second bracket, and a reel 102. The first bracket 101 and the second bracket are arranged on the base 1 at intervals. The reel 102 is rotatably arranged between the first bracket 101 and the second bracket. The reel 102 is hinged to the first bracket 101 and the second bracket via a central axis. After the adhesive tape 3 is wound into a roll 3, it can be placed on the reel 102. The adhesive tape 3 in the factory is generally purchased in rolls, that is, the purchased adhesive tape 3 is a roll 3 of adhesive tape 3. The purchased roll 3 of adhesive tape 3 can be directly placed on the reel 102. The adhesive tape 3 on the roll 3 is cut by a cutting device to obtain the required length of adhesive tape 3. When the adhesive tape 3 is cut, the adhesive tape 3 is attached to the base 1.

[0041] The cutting tool 2 includes a drive handle 20, a first cutter 21, a second cutter 22, and a third cutter 23. One end of the drive handle 20 is hinged to the base 1, and the other end of the drive handle 20 is free. Specifically, the base 1 has a third bracket 14 and a fourth bracket 15, which are spaced apart. The third bracket 14 and the fourth bracket 15 are respectively located near the first bracket 101 and the second bracket, and are located outside the first bracket 101 and the second bracket. The end of the drive handle 20 away from the free end is provided with two articulated arms 201, which are spaced apart, with one articulated arm 201 articulated to the third bracket 14 and the other articulated arm 201 articulated to the fourth bracket 15. When the tape 3 is placed on the reel 102, the two spaced apart articulated arms 201 can clear the tape 3 and prevent it from interfering with the drive handle 20. The driving handle 20 is hinged to the third bracket 14 and the fourth bracket 15 respectively through two hinged arms 201. When the cutting tool 2 cuts the tape 3, the cutting tool 2 will not deviate to one side, ensuring that the tape 3 can be cut.

[0042] The first, second, and third cutters 21, 22, and 23 are sequentially positioned on the drive handle 20. The first cutter 21 is positioned near the free end of the drive handle 20, while the third cutter 23 is positioned near the hinged arm 201 of the drive handle 20. The first, second, and third cutters 21, 22, 23 are spaced apart from each other. A predetermined distance exists between the first and second cutters 21, 22, which represents the length of the stripping aid left on the tape 3 after the cut. When the cutting tool 2 cuts the tape 3, the first and third cutters 21, 23 sever the adhesive strip 31 and the release paper 30 from the tape 3. The distance between the first and third cutters 21, 23 determines the length of the tape 3 cut by the cutting device. The second cutter 22 severing the adhesive strip 31 from the tape 3 leaves a predetermined distance of release paper 30 between the first and second cutters 21, 22, which serves as a stripping aid. That is, after the second cutter 22 cuts down, the cutting height is higher than that of the first cutter 21 and the third cutter 23 to avoid completely cutting the tape 3. After the second cutter 22 cuts down, the height of the blade is higher than that of the first cutter 21 and the third cutter 23 by the thickness of the release paper 30, ensuring that the second cutter 22 does not cut the release paper 30, but only cuts the adhesive strip 31 of the tape 3.

[0043] The specific implementation method for preserving the stripping aid after the tape 3 is cut by the cutting device of this embodiment is as follows: an upwardly projecting structure 11 is provided on the upper edge of the base 1 below the second cutter 22. When the tape 3 is laid flat on the base 1, the height of the adhesive strip 31 is greater than or equal to the height of the upwardly projecting structure 11, allowing the second cutter 22 to completely cut the adhesive strip 31. Furthermore, when the cutting tool 2 cuts the tape 3, the upwardly projecting structure 11 abuts against the second cutter 22, limiting its position and preventing it from moving downward. This ensures that the second cutter 22 only cuts the adhesive strip 31 of the tape 3 and does not cut the release paper 30. Furthermore, an upwardly projecting structure 11 is provided on each end of the base 1 near the second cutter 22. When the cutting tool 2 cuts the tape 3, the two upwardly projecting structures 11 abut against the ends of the second cutter 22. The two upward convex structures 11 respectively limit the two ends of the second cutter 22 to ensure that the second cutter 22 will not deviate to one side and ensure that the release paper 30 will not be cut.

[0044] During actual use, the cutting tool 2 of this embodiment is rotatably set on the base 1, and includes a first cutter 21, a second cutter 22 and a third cutter 23 which are sequentially arranged on the driving handle 20. When cutting the tape 3, the first cutter 21 and the third cutter 23 cut off both ends of the tape 3, that is, the adhesive strip 31 and the release paper 30 of the tape 3 are both cut, so that the distance between the first cutter 21 and the third cutter 23 determines the length of the cut tape 3; and there is a preset distance between the first cutter 21 and the second cutter 22, and the second cutter 22 only cuts the adhesive strip 31 on the tape 3, but does not cut the release paper 30 on the tape 3. After each cutting, the release paper 30 on the tape 3 between the first cutter 21 and the second cutter 22 serves as a peeling aid for the tape 3, making it convenient for customers to tear off the release paper 30 after bonding the tape 3 to the exterior trim of the car. That is, the tape 3 cutting device can cut the tape 3 according to the required distance, and a peeling head can be reserved after cutting to facilitate customers to tear off the release paper 30 without adding an additional peeling head, which can improve the work efficiency of tape 3 cutting and reduce costs.

[0045] The mounting position of the third cutter 23 on the driving handle 20 is adjustable to adjust the spacing between the third cutter 23 and the first cutter 21. The first and second cutters 21 and 22 are fixed in position, as the distance between them determines the length of the stripping aid. The third cutter 23 is adjustable to adjust the spacing between the third cutter 23 and the first cutter 21, which determines the length of the tape 3 cut. Specifically, the driving handle 20 has an elongated slot 200 extending along its length. This slot 200 is a waist-shaped slot. A fixing member 24 extends through the slot 200 to secure the third cutter 23 to the driving handle 20. The fixing member 24 can be adjusted along the slot 200, and the fixing member 24 can be a screw or bolt. When it is necessary to cut a longer tape 3, it is only necessary to fix the third cutter 23 on the end of the long groove 200 close to the hinged arm 201; when it is necessary to cut a shorter tape 3, it is only necessary to fix the third cutter 23 on the end of the long groove 200 close to the free end.

[0046] Furthermore, the base 1 is provided with two positioning plates 12 for positioning the tape 3. The two positioning plates 12 are spaced apart, and the tape 3 can pass through between the two positioning plates 12. The spacing between the two positioning plates 12 is adjustable to position tapes 3 of different widths. A waist hole is provided on the positioning plate 12 in a direction perpendicular to the tape 3, and bolts are passed through the waist hole to fix the positioning plate 12 on the base 1, so that the spacing between the two positioning plates 12 is adjustable, thereby achieving the positioning of tapes 3 of different widths. In actual use, the installation position of the third cutter 23 of this embodiment is adjustable, and the spacing between the third cutter 23 and the first cutter 21 can be adjusted, thereby cutting out tapes 3 of different lengths. The spacing between the two positioning plates 12 is adjustable, which is suitable for tapes 3 of different widths. The cutting device can cut tapes 3 of different lengths and widths.

[0047] In this embodiment, the first, second, and third cutters 21, 22, and 23 are all detachably fixedly mounted on the drive handle 20, facilitating replacement and maintenance of the first, second, and third cutters 21, 22, and 23. Each of the first, second, and third cutters 21, 22, and 23 includes a cutter head 212 and a blade 211 detachably fixedly connected to the cutter head 212, facilitating individual replacement of the blades 211 of each of the first, second, and third cutters 21, 22, and 23. A V-shaped groove 16 is also provided on the upper edge of the base 1 below the first cutter 21. When the cutting tool 2 cuts the tape 3, the first cutter 21 engages in the V-shaped groove 16, ensuring that the first cutter 21 can cut the tape 3. The third cutter 23 does not have a V-shaped groove 16 below it because its position is adjustable.

[0048] Preferably, a limit block 13 is provided on the base 1. The limit block 13 is rotatably disposed on the base 1 and is close to the third cutter 23. The limit block 13 can be rotated to below the third cutter 23 or the driving handle 20 to limit the cutting tool 2, and the limit block 13 can be rotated away from below the third cutter 23 or the driving handle 20. During use, when the tape 3 is not being cut, the limit block 13 is rotated to below the third cutter 23 or the hinged arm 201 of the driving handle 20 to prevent the cutting tool 2 from cutting the worker's fingers downward, thereby ensuring the worker's operational safety. When the tape 3 needs to be cut, the limit block 13 is rotated away from below the third cutter 23 or the hinged arm 201 of the driving handle 20, and no longer restricts the cutting tool 2 from performing a downward cutting action. In addition, a limit block 13 is set on both sides of the driving handle 20. No matter whether the worker operates with his left hand or right hand, it is convenient for the worker to rotate the limit block 13 with his other hand to limit the cutting tool 2 or no longer limit the cutting tool 2, which is convenient for operation.

[0049] In this solution, after the tape cutting device cuts the tape 3, a section of release paper 30 can be left at one end of the tape 3 as a peeling aid, making it convenient for customers to tear off the release paper 30; and the tape 3 can be cut into different lengths, and can also be suitable for tapes 3 of different widths. The cutting device has high cutting efficiency, high cutting accuracy, and a wide range of applications.
