Abstract
Description
Technical Field
[0001] This application belongs to the field of tape production technology, specifically a tape roll coarse shearing device. Background Technology
[0002] Adhesive tape is a material that uses an adhesive substance to temporarily or permanently connect two or more objects. Its core function is to use surface adhesion to achieve purposes such as fixing, sealing, wrapping, or marking.
[0003] Currently, after tape rolls are produced, their shape is often a long cylinder. However, in normal sales or use, it is often unnecessary to use such long tapes. Therefore, it is often necessary to cut them into cylindrical sections according to actual needs, that is, to cut a long cylindrical tape into multiple shorter cylindrical tapes. However, when cutting the tape, workers often need to manually place the tape under the cutter to facilitate cutting. Since the cutter is usually positioned directly above the tape being cut when not cutting, if there is loosening between the cutter and the cutter holder, or if the support component that provides support to the cutter holder malfunctions, the cutter may fall naturally under gravity. If the worker is controlling the tape at this time, it may easily cause injury. Therefore, it is necessary to design a tape roll coarse shearing device to solve the above problems. Utility Model Content
[0004] The purpose of this application is to address the shortcomings of existing technologies by designing a tape roll coarse shearing device that uses a pusher assembly to push the tape roll and a baffle to block the cutting area, thus solving the problem of worker injury during the cutting process.

[0008] Preferably, the drive assembly includes a cylinder, the lower surface of which is fixedly connected to the upper surface of the bracket, and the output shaft of the cylinder passes through the inner wall of the bracket and is fixedly connected to the middle of the upper surface of the moving block.
[0009] Preferably, it also includes a limiting mechanism, which is fixedly installed inside the bracket, the limiting mechanism is signal-connected to the cylinder, and the limiting mechanism is fixedly connected to the upper surface of the moving block.
[0010] Preferably, the limiting mechanism includes a signal transmitter, a signal receiver, a sliding rod, and a mechanical limiting component. The rear surface of the signal transmitter is fixedly connected to the inner wall surface of the rear side of the upper right corner region of the bracket. The front surface of the signal receiver is fixedly connected to the inner wall surface of the front side of the upper right corner region of the bracket. The projections of the signal transmitter and the signal receiver on the rear surface of the bracket coincide. There is a preset distance between the signal transmitter and the signal receiver, and this distance is greater than the diameter of the sliding rod. The lower end of the sliding rod is fixedly connected to the upper surface of the moving block. The sliding rod is disposed between the signal transmitter and the signal receiver. The mechanical limiting component is coaxially fixed on the outer circumferential surface of the sliding rod.
[0011] Preferably, the mechanical limiting assembly includes a limiting block, a pressure block, a threaded rod, and a fixing sleeve.

[0014] 2. This application adopts a limiting mechanism to ensure that the falling range of the cutter is limited, thereby ensuring that the cutter can descend to the position of completely cutting the tape roll, while not easily damaging the equipment due to excessive falling distance, thus achieving the effect of preventing damage to the equipment during use and affecting its lifespan.

[0017] Reference Figure 1 - Figure 4A tape roll coarse shearing device includes a base plate 1, a support 2, a cutting mechanism 6, a drive assembly 7, and a baffle 8. The lower end of the support 2 is fixedly connected to the upper surface of the base plate 1. The support 2 is U-shaped and located in the middle of the base plate 1 in the front-rear direction. The left surface of the support 2 is coplanar with the left surface of the base plate 1, and the right surface of the support 2 is coplanar with the right surface of the base plate 1. A through groove 3 with vertical communication is opened on the inner wall of the base plate 1 in front of the support 2. A transmission roller 4 is rotatably connected to the inner wall of the through groove 3. The top of the transmission roller 4 is connected to... The upper surface of the base plate 1 is coplanar. A pusher assembly 5 is fixedly installed on the upper surface of the base plate 1 in front of the conveyor roller 4. The pusher assembly 5 is used to push the tape roll to the cutting area, thereby ensuring that the tape roll does not need to be manually moved by the operator. The cutting mechanism 6 is slidably installed on the inner side of the bracket 2. The cutting mechanism 6 is used to cut the tape roll. The drive assembly 7 is fixedly connected to the upper surface of the bracket 2. The output shaft of the drive assembly 7 passes through the inner wall of the bracket 2 and is fixedly connected to the top of the cutting mechanism 6. The baffle 8 is fixedly connected to the front surface of the bracket 2.
[0018] In this embodiment, during use, the operator first places the tape roll on the conveyor roller 4, and then pushes the tape roll placed above the conveyor roller 4 to a position directly below the cutting mechanism 6 via the pusher assembly 5. Since the tape roll is pushed by the pusher assembly 5 at this time, the operator does not need to manually adjust its position. Because the cutting area is located behind the baffle 8, the baffle 8 can further prevent the operator from putting their hands into this area. After the tape roll is moved to this area, the drive assembly 7 is activated, which enables the cutting mechanism 6 to cut the tape roll. After cutting is completed, the tape roll is first... The drive component 7 drives the cutting mechanism 6 to reset, and then the pusher component 5 continues to push the tape roll backward, thereby ensuring that the new cutting point of the tape roll is moved directly below the cutting mechanism 6. As the tape roll moves backward, the finished product that has been cut is pushed to the rear of the cutting area, so that the staff can take the finished product away in this area. At the same time, since the new cutting point of the tape roll is directly below the cutting mechanism 6 after the movement, the drive component 7 is started again to drive the cutting mechanism 6 to move down, so that the tape roll can be cut again until the entire tape roll is cut.
[0019] As a preferred embodiment, the feeding assembly 5 includes a fixed plate 51, a slide bar 52, a push block 53, and a handheld block 54. The lower surface of the fixed plate 51 is fixedly connected to the upper surface of the base plate 1 near the front side. The rear surface of the fixed plate 51 is located in front of the front surface of the through groove 3. The position setting ensures that the fixed plate 51 will not prevent the conveyor roller 4 from failing to contact the tape roll. The outer wall of the slide bar 52 passes through and is slidably connected to the inner wall of the fixed plate 51. The rear end of the slide bar 52 is fixedly connected to the front surface of the push block 53. The outer wall of the slide bar 52 near the front side passes through and is fixedly connected to the inner wall of the handheld block 54. By pushing the handheld block 54, the operator causes the handheld block 54 to move the slide bar 52 backward, which in turn causes the slide bar 52 to move the push block 53 backward. As the push block 53 moves backward, it can push the tape roll behind it to move backward, thereby achieving the desired effect.
[0020] As a preferred embodiment, the cutting mechanism 6 includes a movable block 61 and a cutter 62. The left and right sides of the movable block 61 are slidably connected to the inner wall of the support 2. The movable block 61 slides up and down relative to the support 2. The output shaft of the drive assembly 7 is fixedly connected to the upper surface of the movable block 61. The upper surface of the cutter 62 is fixedly connected to the lower surface of the movable block 61. The cutter 62 is used to cut the tape roll.
[0021] As a preferred embodiment, the drive assembly 7 includes a cylinder 71, the lower surface of which is fixedly connected to the upper surface of the bracket 2. The output shaft of the cylinder 71 passes through the inner wall of the bracket 2 and is fixedly connected to the middle of the upper surface of the moving block 61. When the output shaft of the cylinder 71 drives the moving block 61 to move downward, the moving block 61 can drive the cutter 62 to move downward synchronously with it, thereby achieving the effect of cutting the tape roll.
[0022] As a preferred embodiment, a limiting mechanism 9 is also included. The limiting mechanism 9 is fixedly installed inside the bracket 2 and is signal-connected to the cylinder 71. When the limiting mechanism 9 receives a limiting signal, it transmits the signal to the cylinder 71, causing the output shaft of the cylinder 71 to stop moving downward, thereby achieving the limiting effect. The limiting mechanism 9 is fixedly connected to the upper surface of the moving block 61.
[0023] In a preferred embodiment, the limiting mechanism 9 includes a signal transmitter 91, a signal receiver 92, a sliding rod 93, and a mechanical limiting assembly 94. The rear surface of the signal transmitter 91 is fixedly connected to the inner wall surface of the rear side of the upper right corner region of the bracket 2, and the front surface of the signal receiver 92 is fixedly connected to the inner wall surface of the front side of the upper right corner region of the bracket 2. The projections of the signal transmitter 91 and the signal receiver 92 on the rear surface of the bracket 2 coincide. By positioning the signal transmitter 91 and the signal receiver 92, it is ensured that the signal receiver 92 can receive the signal emitted by the signal transmitter 91. A preset distance is maintained between the sliding rod 93 and the moving block 61, and this distance is greater than the diameter of the sliding rod 93. The lower end of the sliding rod 93 is fixedly connected to the upper surface of the moving block 61. When the moving block 61 moves up and down, the sliding rod 93 moves up and down accordingly. The sliding rod 93 is positioned between the signal transmitter 91 and the signal receiver 92. When the sliding rod 93 slides down to the point where it does not block the signal emitted by the signal transmitter 91, the signal receiver 92 can receive the signal. When the signal receiver 92 receives the signal, it transmits a stop signal to the cylinder 71, causing the output shaft of the cylinder 71 to stop moving downward. The mechanical limit assembly 94 is coaxially fixed on the outer circumferential surface of the sliding rod 93.
[0024] As a preferred embodiment, the mechanical limiting assembly 94 includes a limiting block 941, a pressure block 942, a threaded rod 943, and a fixing sleeve 944. The inner wall of the limiting block 941 penetrates and contacts the outer circumferential surface of the sliding rod 93. The inner diameter of the limiting block 941 is larger than the outer diameter of the sliding rod 93. By setting the size of the inner diameter of the limiting block 941 and the outer diameter of the sliding rod 93, it is ensured that the limiting block 941 can slide up and down relative to the sliding rod 93 when not locked, thereby ensuring that the operator can fine-tune the limiting distance according to actual needs. The outer wall of the pressure block 942 is slidably connected to the inner wall of the limiting block 941. The front surface of the threaded rod 943 is rotatably connected to the rear surface of the pressure block 942. The outer wall of the threaded rod 943 penetrates and is threadedly connected to the inner wall of the limiting block 941. The side of the fixing sleeve 944 away from the cylinder 71 is fixedly connected to the inner wall of the bracket 2. The outer wall of the sliding rod 93 penetrates and is threadedly connected to the fixing sleeve. The inner wall of 944 is slidably connected. When the operator rotates the threaded rod 943 and moves it backward during rotation, the threaded rod 943 drives the pressure block 942 to move backward, thus preventing the pressure block 942 from contacting the outer circumferential surface of the sliding rod 93. At this time, the limiting block 941 relative to the sliding rod 93 is released. The operator can adjust the height position of the limiting block 941 relative to the sliding rod 93 as needed. After adjustment, the threaded rod 943 is rotated in the opposite direction to ensure that the threaded rod 943 drives the pressure block 942 forward during rotation, so that the front surface of the pressure block 942 is in contact with the outer circumferential surface of the sliding rod 93. This keeps the limiting block 941 relatively fixed to the sliding rod 93 under the action of friction. When the equipment is in normal use, the limiting block 941 remains in a relatively fixed state with the sliding rod 93.
[0025] As a preferred embodiment, a support base 10 is also included. The upper surface of the support base 10 is fixedly connected to the lower surface of the base plate 1. By setting the support base 10, it is ensured that the handheld block 54 can be at a height that is convenient for the staff to push, and the staff will not be inconvenient to operate due to the height of the handheld block 54 being too low.
