Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of adhesive tape cutting equipment, in particular to an adhesive tape cutting device. BACKGROUND

[0002] An adhesive tape cutting device is a tool used to accurately and quickly cut adhesive tapes (such as transparent tapes, electrician tapes, cloth-based tapes, etc.) into the desired length. It has a wide range of applications in industrial production, packaging, office work, and daily household use. Initially, people used scissors or blades to cut adhesive tapes by hand, which was not only inefficient but also wasteful. With the advancement of technology, various types of adhesive tape cutting machines have appeared on the market, from simple manual cutters to semi-automatic and even fully automatic adhesive tape cutting systems, greatly improving work efficiency and cutting accuracy.

[0003] In some industries, such as the electronics manufacturing industry, the size requirements for adhesive tapes are very strict, and manual cutting cannot achieve the required accuracy. Therefore, mechanical equipment needs to be used for cutting, and the mechanical equipment needs to have high flexibility and accuracy so that the adhesive tapes that meet the requirements can be cut.

[0004] Chinese patent document CN111115339B discloses an adhesive tape cutting device, which comprises a base, a feeding mechanism for supplying adhesive tapes, the number of the feeding mechanisms is at least two, at least one feeding mechanism is arranged on each side of the base and symmetrically distributed, a feeding mechanism installed on the base, the feeding mechanism comprises a feeding driving member and multiple groups of first clamping assemblies, each group of the first clamping assemblies corresponds to one of the feeding mechanisms, the feeding driving member can drive multiple groups of the first clamping assemblies to move synchronously, so that multiple groups of the first clamping assemblies can synchronously clamp and transport the adhesive tapes supplied by the feeding mechanisms, and a cutting mechanism installed on the base and used for cutting the adhesive tapes. The adhesive tape cutting device described above can drive multiple groups of the first clamping assemblies to synchronously clamp and transport the adhesive tapes by the same feeding driving member, which is low in cost and low in energy consumption. Although the above-mentioned device can cut adhesive tapes, its structure is relatively complex and is troublesome to maintain. Moreover, the device occupies a large space and is inconvenient to install. UTILITY MODEL CONTENT

[0005] One of the technical problems to be solved by the present disclosure is how to solve the problem of complex structure of the adhesive tape cutting device.

[0006] To solve the above technical problems, the present disclosure provides an adhesive tape cutting device, which is at least used for cutting adhesive tapes, the adhesive tapes are wound to form adhesive tape rolls, and the adhesive tape cutting device comprises:

[0007] a base;

[0008] The first body is arranged on the base, and the first body is provided with a unwinding part for placing the adhesive tape roll and a cutting part for cutting the adhesive tape;

The first end of the adjusting device is fixed to the base, the second end of the adjusting device is connected to the clamping cylinder, and the second end of the adjusting device can slide relative to the first end along the first direction to adjust the distance between the first clamp jaw and the first body.

[0015] In some embodiments, the first body is further provided with a clamping part, which is slidingly connected to the first body and slides along a second direction to clamp the adhesive tape. The second direction is perpendicular to the first direction.

Then, the stretching part on the second main body can move along the first direction to gradually approach the first main body, and when the stretching part moves to a position sufficient to clamp the adhesive tape, the stretching part can clamp the adhesive tape and pull it out of the adhesive tape roll towards the second main body. When the pulled adhesive tape meets the required length, the stretching part stops moving. Finally, the cutting part can cut the pulled adhesive tape, i.e. cut the adhesive tape into the required length.

[0035] The techniques, methods, and devices known to those skilled in the relevant art can not be discussed in detail, but in appropriate cases, the techniques, methods, and devices should be considered as part of the specification.

[0036] In order to solve the problem of complex structure of the adhesive tape cutting device. According to the embodiments of the present application, an adhesive tape cutting device is provided. The adhesive tape cutting device of the present application will be described in detail below with reference to the accompanying drawings.

[0037] Referring to Figures 1 to 2 As shown, according to the embodiments of the present application, an adhesive tape cutting device is provided, which is at least used for cutting adhesive tape 1, the adhesive tape 1 is wound to form an adhesive tape roll 11, and the adhesive tape cutting device comprises a base 2, a first body 3 and a second body 4.

[0038] The first body 3 is arranged on the base 2, and the first body 3 is provided with a winding-off part 31 for placing the adhesive tape roll 11 and a cutting part 32 for cutting the adhesive tape 1. The second body 4 is arranged on the base 2 and is spaced apart from the first body 3 along a first direction, and the distance between the second body 4 and the first body 3 is adjustable. The second body 4 is provided with a stretching part 41 for stretching the adhesive tape 1 for cutting by the cutting part 32, and the second body 4 is provided with a first driving part 42 for driving the stretching part 41 to move along the first direction.

[0039] In the present application, when the tape cutting device is actually assembled, the distance between the first body 3 and the second body 4 can be adjusted as needed, and after the appropriate distance is adjusted, the first body 3 and the second body 4 are fixed on the base 2 respectively. In actual work, first, the operator places the tape roll 11 at the unwinding part 31, and then pulls the tape 1 from the tape roll 11 and clamps it at the corresponding position of the first body 3 (i.e. the clamping part 33). Then, the stretching part 41 on the second body 4 can gradually move closer to the first body 3 in the first direction (i.e. the direction of x in Figure 1 When the stretching part 41 moves to a position sufficient to clamp the tape 1, the stretching part 41 can clamp the tape 1 and pull it out of the tape roll 11 in the direction of approaching the second body 4 (i.e. the opposite direction of the direction of x in Figure 1 When the tape 1 pulled out meets the required length, the stretching part 41 stops moving. Finally, the cutting part 32 can cut the tape 1 pulled out, that is, the tape 1 is cut into the required length. Repeating the above operation can continuously cut the tape 1, thereby obtaining multiple pieces of tape 1 of the required length.

[0040] That is, compared with the existing tape cutting device, the tape cutting device of the present application has a simple structure, and the tape 1 can be pulled out of the tape roll 11 and cut into the required length by a simple operation process. Therefore, the tape cutting device of the present application can solve the problem of complex structure of the tape cutting device.

[0041] In some embodiments, as shown in Figure 1 and Figure 2 The stretching part 41 includes a first clamping jaw 411 and a clamping cylinder 412, the first clamping jaw 411 has a first state of clamping jaw opening and a second state of clamping jaw closing, and the clamping cylinder 412 drives the first clamping jaw 411 to switch between the first state and the second state.

[0042] Specifically, in general cases (i.e. the first clamping jaw 411 is away from the first body 3 and does not clamp the tape 1), the first clamping jaw 411 is in the first state, and when the first clamping jaw 411 clamps the tape 1, the first clamping jaw 411 is in the second state. In actual work, first, place the tape roll 11 at the unwinding part 31, and pull the tape 1 out of the tape roll 11 and clamp it at the corresponding position of the first body 3 (i.e. the clamping part 33). Then, control the stretching part 41 to move in the first direction (i.e. the direction of x in Figure 1In this process, the first clamping jaw 411 is in the open state (first state), and when the stretching part 41 moves to the position where the adhesive tape 1 can be clamped, the clamping cylinder 412 drives the first clamping jaw 411 to switch from the first state to the second state to clamp the adhesive tape 1. Then the stretching part 41 moves the adhesive tape 1 towards the second body 4, and in this process, the first clamping jaw 411 always clamps the adhesive tape 1. When the adhesive tape 1 of the required length is pulled out, the stretching part 41 stops moving. Finally, the cutting part 32 on the first body 3 starts to work to cut the pulled-out adhesive tape 1, and then the clamping cylinder 412 drives the first clamping jaw 411 to switch from the second state to the first state to release the cut adhesive tape 1, thereby completing the cutting of the adhesive tape 1. By continuously repeating the above operation, the adhesive tape 1 can be continuously cut into the required length.

[0043] In some embodiments, as shown in Figure 1 and Figure 2 The clamping cylinder 412 includes a cylinder body 4121 which is slidingly connected to the base 2, and the sliding direction of the cylinder body 4121 is the same as the first direction, and the first clamping jaw 411 is arranged at one end of the cylinder body 4121 close to the first body 3.

[0044] Specifically, in the present application, a sliding guide rail (not shown in the figure) can be arranged between the cylinder body 4121 and the base 2 to slidingly connect the cylinder body 4121 to the base 2, and the sliding guide rail extends along the first direction. A protrusion (not shown in the figure) can also be arranged on one of the cylinder body 4121 and the base 2, and a sliding groove (not shown in the figure) can be arranged on the other one of the cylinder body 4121 and the base 2, and the protrusion and the sliding groove are matched to slidingly connect the cylinder body 4121 to the base 2, and both the protrusion and the sliding groove extend along the first direction. A pulley (not shown in the figure) can also be arranged on one of the cylinder body 4121 and the base 2 to slidingly connect the cylinder body 4121 to the base 2. In order to prevent the cylinder body 4121 from shaking during sliding, the sliding guide rail or the sliding groove is generally used to slidingly connect the cylinder body 4121 to the base 2 in the present application. In addition, the sliding connection mode of the sliding guide rail or the sliding groove can also increase the structural stability between the cylinder body 4121 and the base 2, so that the sliding connection structure between the cylinder body 4121 and the base 2 is not easily damaged during work.

[0045] In some embodiments, as shown in Figure 1 and Figure 2 The stretching part 41 further includes a connecting plate 413, and the first driving part 42 includes a first driving device 421. The connecting plate 413 is fixedly connected to the outer side of the cylinder body 4121, the power output end of the first driving device 421 is fixedly connected to the connecting plate 413, and the first driving device 421 at least drives the clamping cylinder 412 to slide along the first direction.

[0046] Specifically, the connecting plate 413 plays a role of connection and motion transmission between the first driving device 421 and the clamping cylinder 412. If the connecting plate 413 is not provided, the power output end of the first driving device 421 needs to be directly fixedly connected to the cylinder body 4121 of the clamping cylinder 412, which is easy to cause damage to the cylinder body 4121. Moreover, if the connecting plate 413 is not provided, when the adhesive tape cutting device needs to be maintained or repaired, the disassembly between the first driving device 421 and the clamping cylinder 412 is difficult, which is not conducive to the maintenance or repair of the cutting device. In addition, in some embodiments of the present application, the motion direction of the power output end of the first driving device 421 is parallel to the first direction, so that the power output end of the first driving device 421 is fixedly connected to the cylinder body 4121 by the connecting plate 413, so that the clamping cylinder 412 can move in the first direction under the drive of the first driving device 421. In other embodiments of the present application, the motion direction of the power output end of the first driving device 421 can be parallel to the first direction. Since the motion direction of the power output end of the first driving device 421 is not parallel to the first direction, the power output end of the first driving device 421 can be connected to the connecting plate 413 in a hinged manner, so that the clamping cylinder 412 can move in the first direction under the drive of the first driving device 421.

[0047] In some embodiments, as shown in Figure 1 and Figure 2 The first driving part 42 further comprises an adjusting device 422, a first end of the adjusting device 422 is fixed to the base 2, and a second end of the adjusting device 422 is connected to the clamping cylinder 412. The second end of the adjusting device 422 can slide relative to the first end in the first direction to adjust the distance between the first clamping jaw 411 and the first main body 3.

[0048] Specifically, in the present application, the adjusting device 422 can adjust the motion stroke of the power output end of the first driving device 421, so that the initial position of the clamping cylinder 412 on the second main body 4 can be adjusted, and the length of the cut adhesive tape 1 can be adjusted. In actual work, first, the clamping cylinder 412 is controlled to return to the second main body 4 by the adjusting device 422 and the first driving device 421, and then the first driving device 421 is started to drive the stretching part 41 to pull out the adhesive tape 1 from the first main body 3 to the second main body 4. When the clamping cylinder 412 moves to the position preset by the adjusting device 422, the first driving device 421 stops moving, at which time the cutting part 32 on the first main body 3 can start to cut the adhesive tape 1, so that the adhesive tape 1 can be cut into the required length.

[0049] In some embodiments, as shown in Figure 1 andFigure 2 As shown, the first body 3 is further provided with a clamping portion 33, which is slidingly connected to the first body 3 and slides along a second direction to clamp the adhesive tape 1, the second direction being perpendicular to the first direction.

[0050] Specifically, the clamping portion 33 is mainly used to clamp the adhesive tape 1, so that the adhesive tape cutting device can be more easily stretched and cut the adhesive tape 1. In actual work, first, the operator pulls the adhesive tape 1 from the adhesive tape roll 11 and clamps it at the clamping portion 33, at which time the clamping portion 33 moves slightly to clamp the adhesive tape 1 along the second direction (i.e., the direction indicated by y in Figure 1 FIG. 2). Then, the stretching portion 41 on the second body 4 moves and clamps the adhesive tape 1 along the first direction (i.e., the direction indicated by x in Figure 1 FIG. 2), at which time the clamping portion 33 moves slightly to loosen the adhesive tape 1 along the direction opposite to the second direction (i.e., the direction opposite to the direction indicated by y in Figure 1 FIG. 2), so that the stretching portion 41 is more easily stretched. Then the stretching portion 41 pulls the adhesive tape 1 in the direction close to the second body 4 (i.e., the direction opposite to the direction indicated by x in Figure 1 FIG. 2), and when the clamping cylinder 412 stops moving, the clamping portion 33 moves along the second direction to firmly clamp the adhesive tape 1. Finally, the cutting portion 32 is started to cut the adhesive tape 1 into the required length. Thus, the above operation is repeated to continuously cut the adhesive tape 1.

[0051] In addition, in some embodiments of the present application, the second direction is arranged perpendicular to the first direction, and in some embodiments of the present application, the second direction can also be a direction different from the first direction. When the second direction is a direction different from the first direction, the structure of the clamping portion 33 is more complex than when the second direction is perpendicular to the first direction, and the movement required by the clamping portion 33 is also correspondingly longer, which can increase the size of the adhesive tape cutting device.

[0052] In some embodiments, as shown in Figure 1 and Figure 2 The clamping portion 33 includes a second driving device 331, a first clamping piece 332, and a second clamping piece 333. The first clamping piece 332 is fixedly connected to the base 2, the second clamping piece 333 is slidingly arranged on the base 2, and the second driving device 331 drives the second clamping piece 333 to slide along the second direction to clamp the adhesive tape 1 located between the first clamping piece 332 and the second clamping piece 333.

[0053] Specifically, the first clamping piece 332 and the second clamping piece 333 are respectively located in the thickness direction of the adhesive tape 1 (i.e., the direction indicated by z in Figure 1The two sides are different in the direction indicated by y, that is, the adhesive tape 1 is located between the first clamping member 332 and the second clamping member 333. When the clamping portion 33 needs to clamp the adhesive tape 1, the second clamping member 333 is driven by the second driving device 331 to move in the direction indicated by y to clamp the adhesive tape 1. When the clamping portion 33 needs to release the adhesive tape 1, the second clamping member 333 is driven by the second driving device 331 to move in the direction opposite to the direction indicated by y to release the adhesive tape 1. It should be noted that, after the positions of the first clamping member 332 and the second clamping member 333 are exchanged in the embodiment shown in Figure 1 , when the clamping portion 33 needs to clamp or release the adhesive tape 1, the movement direction of the second clamping member 333 is opposite to the movement direction described above.

[0054] In some embodiments, as shown in Figure 1 and Figure 2 , the unwinding portion 31 includes an unwinding shaft 311, the unwinding shaft 311 is rotationally arranged on the base 2, and the adhesive tape roll 11 is sleeved on the unwinding shaft 311 and rotates with the unwinding shaft 311 in a predetermined direction.

[0055] Specifically, in some embodiments of the present application, the adhesive tape roll 11 is clamped on the unwinding shaft 311 and can rotate with the unwinding shaft 311, but no relative rotation occurs between the adhesive tape roll 11 and the unwinding shaft 311. In other embodiments of the present application, the adhesive tape roll 11 can not only rotate with the unwinding shaft 311, but also can rotate relative to the unwinding shaft 311. Furthermore, in other embodiments of the present application, the unwinding shaft 311 can be fixed on the base 2, and the adhesive tape roll 11 can rotate relative to the unwinding shaft 311. In addition, in the present application, when the stretching portion 41 stretches the adhesive tape 1, the rotation direction of the adhesive tape roll 11 can be clockwise (that is, the direction indicated by a in Figure 1 ), or counterclockwise (that is, the direction indicated by b in Figure 1 ). The present embodiment shows the case where the rotation direction of the adhesive tape roll 11 is counterclockwise when the stretching portion 41 stretches the adhesive tape 1. In other embodiments of the present application, if the rotation direction of the adhesive tape roll 11 is clockwise, the size and position of some structures of the adhesive tape cutting device can be adjusted accordingly, so that the adhesive tape cutting device can cut the adhesive tape 1 into the required size.

[0056] In some embodiments, as shown in Figure 1 and Figure 2 , the cutting portion 32 includes a cutting knife 321 and a third driving device 322, the third driving device 322 drives the cutting knife 321 to move in the second direction of the adhesive tape cutting device to cut when the stretching portion 41 stretches the adhesive tape 1.

[0057] Specifically, in this application, the cutting scissors 321 are fixedly connected to the power output end of the third drive device 322 and can move with the power output end. After the stretching part 41 stretches the tape 1 to the desired length, the third drive device 322 drives the cutting scissors 321 towards the direction closer to the tape 1 (i.e., Figure 1 The tape 1 is cut to the required length by moving in the opposite direction to the direction indicated by y. While the stretching part 41 is stretching the tape 1, the third drive device 322 drives the cutter 321 in a direction away from the tape 1 (i.e.,...). Figure 1 The tape 1 moves in the direction indicated by y, thus preventing it from being damaged by the cutter 321 during the stretching process.

[0058] In some embodiments, see Figure 1 and Figure 2 As shown. The tape cutting device also includes a detection element (not shown), a controller (not shown), and a detection unit 5. The detection unit 5 is disposed in the clamping part 33. The detection element is used to detect the tape 1 at the detection unit 5 to send a signal to the controller. The controller controls at least one of the stretching part 41 and the first driving part 42 to move along a first direction to stretch the tape 1 according to the signal transmitted by the detection element.

[0059] Specifically, in actual operation, firstly, the operator places the tape roll 11 at the unwinding section 31, then pulls the tape 1 from the tape roll 11 and clamps it at the corresponding position (i.e., the clamping section 33) of the first main body 3 to cover the detection section 5. Simultaneously, the clamping section 33 moves along the second direction (i.e.,... Figure 1 The tape 1 is gently clamped by the movement in the direction indicated by y. Then, the detection element detects the detection part 5. When the detection part 5 is covered by the tape 1, the detection element sends a signal to the controller. After receiving the signal, the controller processes it and controls the stretching part 41 on the second body 4 to move along the first direction (i.e., the direction indicated by y). Figure 1 The gripper 411 moves gradually closer to the first body 3 in the direction indicated by x. During this process, the first gripper 411 is in the first state. When the stretching part 41 moves to a position sufficient to grip the tape 1, the clamping part 33 moves in the opposite direction to the second direction (i.e., Figure 1The stretching part 41 slightly loosens the adhesive tape 1 in the opposite direction of the direction indicated by Y. Then the clamping cylinder 412 drives the first clamping jaw 411 to switch from the first state to the second state to clamp the adhesive tape 1. Then the stretching part 41 clamps the adhesive tape 1 and moves the adhesive tape 1 towards the second body 4. When the adhesive tape 1 is pulled out to the required length, the stretching part 41 stops moving. Then the clamping part 33 moves in the second direction to firmly clamp the adhesive tape 1. Finally, the cutting part 32 on the first body 3 starts working to cut the adhesive tape 1 that is pulled out, and then the clamping cylinder 412 drives the first clamping jaw 411 to switch from the second state to the first state to loosen the cut adhesive tape 1, thereby completing the cutting of the adhesive tape 1. By continuously repeating the above operation, the adhesive tape 1 can be continuously cut into the required length.

[0060] It can be known from the above that the adhesive tape cutting device composed of the base 2, the first body 3, the second body 4 and the detecting part 5 can cut the adhesive tape 1 into the required length. Compared with the existing adhesive tape cutting device, the adhesive tape cutting device of the present application not only has a simple structure, but also is convenient to operate and can save manufacturing cost to a certain extent.
