Description

Technical Field

[0001] This utility model relates to the field of tape production technology, and in particular to a tape cutting device with protective properties. Background Technology

[0002] Adhesive tape is a common household item used to bond objects together. In the production process, the tape is rolled onto a rigid paper tube to form a master roll, which is then cut using a cutter to create finished rolls of tape.

[0003] Currently, in the tape production process, most of the time it is necessary to manually place the tape roll to be cut on the machine. However, the distance between the tape roll and the cutting blade is often relatively small, and the cutting blade is mostly an exposed design, which can easily cause injury to workers. Utility Model Content

[0004] The purpose of this invention is to provide a tape cutting device with protective properties, in order to solve the problem mentioned in the background art that the cutting blades are mostly exposed and easily cause injury to workers.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tape cutting device with protective properties, comprising a moving mechanism and a cutting mechanism. The cutting mechanism is mounted on the moving mechanism and includes a T-shaped bracket mounted on the moving mechanism. One end of the T-shaped bracket is provided with a protective shell. The lower end of the T-shaped bracket is rotatably connected to a transmission rod, and the top end of the transmission rod is rotatably connected to a second slider. The upper end of the T-shaped bracket is slidably connected to a moving shaft, and one end of the moving shaft is connected to a cutting blade, which is located inside the protective shell. The middle part of the moving shaft is connected to a second connecting member, and the second slider is slidably connected to the second connecting member. A servo motor is provided at the middle position of the T-shaped bracket, and the output shaft of the servo motor passes through the T-shaped bracket and is connected to a rotating disk. A connecting rod is provided at the center of the rotating disk and is slidably connected to the transmission rod.

[0006] Preferably, the bottom end of the transmission rod is provided with a first connecting hole, and a first connecting shaft is installed at one end of the T-shaped bracket near the transmission rod, the first connecting shaft being adapted to the first connecting hole.

[0007] Preferably, the transmission rod has a first sliding groove, and a first slider is rotatably connected to one end of the connecting rod away from the center of the rotating disk, and the first slider is adapted to the first sliding groove.

[0008] Preferably, the protective shell has a through hole that is adapted to the moving shaft.

[0009] Preferably, the T-shaped bracket has a second connecting hole, and the centers of the second connecting hole, the rotating disk, and the servo motor are on the same axis.

[0010] Preferably, a second connecting member is slidably connected to one end of the transmission rod near the moving shaft, and the other end of the second connecting member away from the transmission rod is connected to the moving shaft.

[0011] Preferably, the second connector has a second sliding groove, and the upper end of the transmission rod is rotatably connected to a second slider, the second sliding groove being adapted to the second slider.

[0012] Preferably, the T-shaped bracket is equipped with two first connectors, which are distributed at both ends of the T-shaped bracket. The protective shell is installed on one of the first connectors, and the movable shaft is slidably connected to the two first connectors.

[0013] The beneficial effects of this utility model are:

[0014] In this invention, the rotation of a servo motor drives a connecting rod to rotate synchronously. When the connecting rod rotates, it pushes a transmission rod to reciprocate horizontally around its bottom end. This, in turn, drives a moving shaft to reciprocate via a second connecting member. When the moving shaft moves towards the protective shell, it moves the cutting blade outward to facilitate tape cutting. When the moving shaft moves away from the protective shell, it moves the cutting blade inside the protective shell, isolating it from the external environment. This prevents workers from being accidentally injured by the cutting blade when disassembling or assembling the tape roll, further improving the safety of the device. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Specifically, a tape cutting device with protective properties includes a moving mechanism 1 and a cutting mechanism 2. The cutting mechanism 2 is mounted on the moving mechanism 1 and includes a T-shaped bracket 3 mounted on the moving mechanism 1. One end of the T-shaped bracket 3 is provided with a protective shell 11. The lower end of the T-shaped bracket 3 is rotatably connected to a transmission rod 10. The top end of the transmission rod 10 is rotatably connected to a second slider 18. The upper end of the T-shaped bracket 3 is slidably connected to a moving shaft 5. One end of the moving shaft 5 is connected to a cutting blade 6, which is located inside the protective shell 11. The middle part of the moving shaft 5 is connected to a second connecting member 20. The second slider 18 is slidably connected to the second connecting member 20. A servo motor 7 is provided at the middle position of the T-shaped bracket 3. The output shaft of the servo motor 7 passes through the T-shaped bracket 3 and is connected to a rotating disk 8. A connecting rod 9 is provided at the axis of the rotating disk 8 and is slidably connected to the transmission rod 10.

[0022] When in use, the device moves the cutting mechanism 2 to a suitable position via the moving mechanism 1, and then starts the cutting mechanism 2 to cut the tape. During cutting, the servo motor 7 is turned on first, and the rotation of the servo motor 7 drives the connecting rod 9 to rotate synchronously. When the connecting rod 9 rotates, it pushes the transmission rod 10 to rotate back and forth horizontally around the bottom end of the transmission rod 10. This drives the moving shaft 5 to move back and forth through the second connecting member 20. When the moving shaft 5 moves towards the protective shell 11, it drives the cutting blade 6 to move outside the protective shell to facilitate the cutting of the tape. When the moving shaft 5 moves away from the protective shell 11, it drives the cutting blade 6 to move inside the protective shell 11, thereby isolating the cutting blade 6 from the external environment. This prevents workers from being accidentally injured by the cutting blade 6 when disassembling or assembling the tape roll, and further improves the safety of the device.

[0023] Specifically, in this embodiment, a first connecting hole 12 is provided at the bottom end of the transmission rod 10, and a first connecting shaft 13 is installed at one end of the T-shaped bracket 3 near the transmission rod 10. The first connecting shaft 13 is adapted to the first connecting hole 12, so that the transmission rod 10 can be rotatably mounted on the T-shaped bracket 3 through the adaptation of the first connecting shaft 13 and the first connecting hole 12, so that the transmission rod 10 can rotate around the first connecting shaft 13 as the center when it moves.

[0024] Specifically, in this embodiment, a first sliding groove 14 is provided on the transmission rod 10, and a first slider 15 is rotatably connected to one end of the connecting rod 9 away from the center of the rotating disk 8. The first slider 15 is adapted to the first sliding groove 14, so that the connecting rod 9 can establish a connection with the transmission rod 10 through the first slider 15. By rotatably connecting the first slider 15 to the connecting rod 9 and slidingly connecting it in the first sliding groove 14, the connecting rod 9 can drive the transmission rod 10 to move synchronously through the first slider 15 when it rotates, thereby indirectly achieving the purpose of driving the moving shaft 5 to move.

[0025] Specifically, in this embodiment, the protective shell 11 is provided with a through hole 16, which is adapted to the movable shaft 5, so that the movable shaft 5 can be slidably connected to the protective shell 11 through the through hole 16, thereby avoiding the situation where the movable shaft 5 is restricted by the protective shell 11 and cannot move.

[0026] Specifically, in this embodiment, the T-shaped bracket 3 is provided with a second connecting hole 17. The center of the second connecting hole 17, the rotating disk 8 and the servo motor 7 are on the same axis, so that the output shaft of the servo motor 7 can be connected to the rotating disk 8 through the second connecting hole 17, thereby enabling the servo motor 7 to drive the rotating disk 8 to rotate.

[0027] Specifically, in this embodiment, a second connecting member 20 is slidably connected to one end of the transmission rod 10 near the moving shaft 5, and the other end of the second connecting member 20 away from the transmission rod 10 is connected to the moving shaft 5, so that when the transmission rod 10 moves, the moving shaft 5 can maintain synchronous movement with the transmission rod 10 through the second connecting member 20, thereby completing the transmission of power.

[0028] Specifically, in this embodiment, the second connecting member 20 is provided with a second sliding groove 19, and the upper end of the transmission rod 10 is rotatably connected to a second slider 18. The second sliding groove 19 is adapted to the second slider 18, so that the second connecting member 20 can be slidably connected to the transmission rod 10 through the adaptation of the second slider 18 and the second sliding groove 19. When the transmission rod 10 moves, it can drive the moving shaft 5 to move synchronously through the second connecting member 20, thereby achieving the purpose of moving the moving shaft 5.

[0029] Specifically, in this embodiment, two first connectors 4 are installed on the T-shaped bracket 3, and the two first connectors 4 are distributed at both ends of the T-shaped bracket 3. The protective shell 11 is installed on one of the first connectors 4. The moving shaft 5 is slidably connected to the two first connectors 4, so that the moving shaft 5 can be indirectly slidably connected to the T-shaped bracket 3 through the setting of the two first connectors 4, thereby providing support for the setting of the moving shaft 5. At the same time, the two first connectors 4 can provide a limiting function for the moving shaft 5, so that the moving shaft 5 always moves in the horizontal direction, thereby realizing the normal storage of the cutting blade 6.

[0030] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
