Abstract
Description
Technical Field
[0001] This utility model belongs to the field of trademark tape production equipment, and in particular relates to a trademark tape anti-breakage device. Background Technology
[0002] The label tape moves continuously on the production line. During production, tension fluctuations may occur due to various reasons such as foreign objects entering or guide wheels jamming. The current approach is to install tension detection devices on the production line. When the tension on the label tape reaches a certain value, the production line automatically stops to prevent the label tape from being torn apart by continued traction. However, this still carries certain risks. When the tension of the label tape rises rapidly, even if the production line has stopped, the production line will still pull the label tape a short distance due to inertia. Within this distance, the tension of the label tape may exceed its limit, causing the label tape to still break. This is particularly evident in low-strength label tapes. Utility Model Content
[0003] The purpose of this invention is to provide a device to prevent trademark tape from breaking. This invention has the advantage of preventing trademark tape from breaking.
[0004] The technical solution of this utility model is as follows: a trademark with an anti-breakage device, including a frame, N fixed pulleys are rotatably connected to the top of the frame, and N-1 movable pulleys are rotatably and slidably connected to the bottom of the frame. Annular grooves are provided on the outer circumferential surfaces of both the fixed pulleys and the movable pulleys, and the fixed pulleys and the movable pulleys are located on the same plane.
[0005] In the aforementioned trademark tape anti-breakage device, the frame includes two vertical side plates on the left and right, with a separation strip between the two side plates. An upper rotating shaft is provided on the axis of the fixed pulley, with both ends of the upper rotating shaft fixed to the two side plates respectively. The fixed pulley is rotatably connected to the upper rotating shaft.
[0006] In the aforementioned trademark strip anti-breakage device, the isolation strip is close to the horizontal sidewall of the side plate, and the isolation strip is located between the fixed pulley and the movable pulley.
[0007] In the aforementioned trademark tape anti-breakage device, a lower rotating shaft is provided on the axis of the movable pulley, the movable pulley is rotatably connected to the lower rotating shaft, N-1 guide elongated holes are provided on the side plate, a guide slider is provided at the end of the lower rotating shaft located in the guide elongated hole, and a limiting nut connected to the lower rotating shaft is provided on the outside of the guide slider.
[0008] In the aforementioned trademark tape anti-breakage device, the fixed pulley is clearance-fitted with the upper rotating shaft, and the movable pulley is clearance-fitted with the lower rotating shaft, so that both the fixed pulley and the movable pulley can move axially.
[0009] In the aforementioned trademark tape anti-breakage device, the guide slider is screwed to the lower rotating shaft.
[0010] In the aforementioned trademark tape anti-breakage device, the guide elongated hole is inclined, and the lower end of the guide elongated hole is close to the traction end of the trademark tape.
[0011] Compared with existing technologies, this invention features multiple fixed and movable pulleys. The label strip is alternately passed through these pulleys. As the tension of the label strip increases, the movable pulley rises, creating a redundant length on the label strip, thus reducing the tension and preventing the label strip from breaking due to exceeding its tension limit. Therefore, this invention has the advantage of preventing the label strip from breaking.
[0012] Furthermore, further structural improvements are needed:
[0013] By setting a partition strip between the two side plates, a uniform distance is maintained between the two side plates. By placing the partition strip on the horizontal side of the side plates, the top and bottom of the frame are opened, making it easy for workers to wrap the label tape around the moving and fixed pulleys, which is convenient to use.
[0014] The movable and fixed pulleys can move axially and automatically fine-tune to keep aligned with the travel trajectory of the label tape. This prevents the sides of the label tape from being squeezed and bent by the sidewalls of the annular grooves of the movable and fixed pulleys, ensuring that the label tape remains flat after passing through the device and does not reduce the pass rate. At the same time, it can also prevent the label tape from falling off the movable and fixed pulleys and reduce the failure rate.
[0015] By setting the guide hole at an angle, the upward resistance of the movable pulley when the label tape is tensioned can be reduced, making the upward response speed of the movable pulley faster and better preventing the label tape from breaking. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.
[0021] Example: A trademark with an anti-breakage device, such as Figure 1As shown, the machine includes a frame. Four fixed pulleys 1 are rotatably connected to the top of the frame, arranged side-by-side at even intervals. Three movable pulleys 2 are rotatably and slidably connected to the bottom of the frame, also arranged side-by-side at even intervals. Annular grooves 10 are provided on the outer circumferential surfaces of both the fixed pulleys 1 and 2, and the fixed pulleys 1 and 2 are located on the same vertical plane. The annular grooves 10 are used to prevent the label tape 11 from axially detaching from the fixed and movable pulleys and becoming jammed.
[0022] The frame includes two vertical side plates 3 on the left and right, and four square-section isolation strips 4 are provided between the two side plates 3. The isolation strips 4 are screwed to the side plates 3, and the isolation strips 4 keep the two side plates 3 at a uniform distance. An upper rotating shaft 5 is provided on the axis of the fixed pulley 1. The two ends of the upper rotating shaft 5 are fixed to the two side plates 3 respectively. The fixed pulley 1 is rotatably connected to the upper rotating shaft 5. The fixed pulley 1 and the upper rotating shaft 5 are clearance-fitted, and the fixed pulley 1 can move axially.
[0023] The isolation strip 4 is close to the horizontal side wall of the side plate 3. The isolation strip 4 is located between the fixed pulley 1 and the movable pulley 2, so that the top and bottom of the frame are always open and not blocked by the isolation strip 4, making it convenient for workers to pass the trademark tape around the fixed and movable pulleys.
[0024] A lower rotating shaft 6 is provided on the axis of the movable pulley 2. The movable pulley 2 and the lower rotating shaft 6 are rotatably connected and are clearance-fitted. The movable pulley 2 can move axially. The side plate 3 is provided with three guide holes 7. The end of the lower rotating shaft 6 is provided with a guide slider 8 located in the corresponding guide hole 7. The guide slider 8 is screwed to the lower rotating shaft 6 to facilitate the assembly of the movable pulley 2 onto the lower rotating shaft 6. A limiting nut 9 is provided on the outside of the guide slider 8 to connect to the lower rotating shaft 6. The limiting nut 9 prevents the lower rotating shaft 6 from moving axially and coming off.
[0025] The guide hole 7 is inclined, with its lower end close to the traction end of the label tape. When the label tape is tensioned, the movable pulley 2 can move upward more smoothly and respond faster.
[0026] Instructions for use: Fix the label tape 11 to the equipment on the production line. Along the movement path of the label tape 11, alternately pass the fixed pulley 1 and the movable pulley 2. When the label tape is taut, the movable pulley 2 rises to prevent the label tape from breaking. It is necessary to ensure that the movable pulley 2 does not rise to the top before the inertial traction force of the production line disappears. This can be achieved by increasing the length of the guide hole 7, increasing the distance between the fixed pulley 1 and the movable pulley 2, or by increasing the number of fixed and movable pulleys, depending on actual needs.
