Description

Technical Field

[0001] This utility model belongs to the field of tape processing technology, and in particular relates to a tension adjustment mechanism for a tape processing laminating machine. Background Technology

[0002] In the processing of adhesive tape, lamination is a necessary step. Adhesive tape laminating machines are mainly used to laminate adhesive tape to achieve an anti-sticking effect. Existing lamination equipment has simple functions and cannot adjust the tension of the film tape. As a result, the film tape is prone to deviation during lamination and is prone to problems such as bubbles and wrinkles, which reduces the lamination quality.

[0003] To address the aforementioned issues, while the patent in publication number CN213891257U can alter the tension of the film tape to ensure its overall flatness, the adjustment range is fixed. This can easily lead to problems such as the tape breaking due to excessive tension or insufficient tension affecting its performance. Utility Model Content

[0004] The technical problem this invention aims to solve is that the tension adjustment range is fixed, which can easily lead to the tape breaking due to excessive tension or affecting the performance due to insufficient tension.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a tension adjustment mechanism for a tape processing laminating machine, comprising a frame, wherein two sets of the frame are symmetrically distributed, and a horizontal plate is fixedly connected between their inner walls and disposed at the left end of the frame, and further comprising...

[0006] Tension adjustment components, located on the horizontal plate, include

[0007] The pressure cylinder, located at the lower end of the horizontal plate, is used to adjust the tension of the conveyor belt.

[0009] An adjustment mechanism, located between the horizontal plate and the buffer connection mechanism, is used to adjust the vertical position of the pressure cylinder;

[0010] The winding assembly, located between opposite side walls of the frame, is used to wind up the tape.

[0011] Furthermore, the adjustment mechanism includes a servo motor, a first bevel gear, a sleeve, a threaded rod, a second bevel gear, a connecting plate, and a guide rod, wherein:

[0012] The servo motor is fixedly installed on the top of the horizontal plate. The first bevel gear is fixedly connected to the output end of the servo motor. The sleeve vertically penetrates the horizontal plate and is rotatably connected to it. The second bevel gear is fixedly connected to the sleeve and located on the top of the horizontal plate, meshing with the first bevel gear. The threaded rod penetrates the sleeve and is threadedly connected to it. The connecting plate is fixedly connected to the lower end of the threaded rod. The lower end of the guide rod is fixedly connected to the top of the connecting plate, and the upper end vertically penetrates the horizontal plate and is slidably connected to it. The guide rods are symmetrically distributed on both sides of the sleeve.

[0013] Furthermore, the buffer connection mechanism includes a sliding column and a connecting frame, wherein:

[0014] The sliding column penetrates the connecting plate vertically and is slidably connected to it, and is symmetrically distributed at both ends of the connecting plate. The connecting frame is fixedly connected to the lower end of the sliding column and is arranged in a ∩ shape. A spring is sleeved on the sliding column, and the connecting frame and the connecting plate are fixedly connected at both ends. The pressure cylinder is rotatably connected between the inner walls of the connecting frame.

[0015] Furthermore, the winding assembly includes a stepper motor, a winding drum, and a guide drum, wherein:

[0016] The stepper motor is fixedly installed on the outer wall of the frame. One end of the take-up drum is fixedly connected to the output end of the stepper motor, and the other end is rotatably connected to the inner wall of another set of frames. The guide cylinder is rotatably connected between the inner walls of the frames and is symmetrically distributed relative to the cross plate.

[0017] Furthermore, heating cylinders arranged linearly are rotatably connected between the inner walls of the frame, and limit rings are fixedly connected to both ends of the heating cylinders. Electric heating rods are fixedly connected between the inner walls of the heating cylinders, and heat insulation cotton is provided on the inner wall of the heating cylinders.

[0018] Furthermore, both the guide rod and the sliding column are T-shaped, and the diameter of the limiting ring is larger than the diameter of the heating cylinder.

[0019] The beneficial effects of this utility model after adopting the above structure are as follows:

[0020] (1) The electric heating rod heats the heating cylinder and ensures the heating effect of the heating cylinder on the tape. Heating the tape can make the tape bond more tightly after lamination.

Detailed Implementation

[0030] like Figure 1-2 As shown, a tension adjustment mechanism for a tape processing laminating machine includes a frame 1. Two sets of cross plates are symmetrically distributed on the frame 1, and a cross plate is fixed between their inner walls and located at the left end of the frame 1. The mechanism also includes a tension adjustment component and a winding component. The tension adjustment component is located on the cross plate and includes a pressure cylinder 2, a buffer connecting mechanism, and an adjustment mechanism. The pressure cylinder 2 is located at the lower end of the cross plate and is used to adjust the tension of the tape. The buffer connecting mechanism is located at the upper end of the pressure cylinder 2 and is used to buffer the pressure cylinder 2. The adjustment mechanism is located between the cross plate and the buffer connecting mechanism and is used to adjust the vertical position of the pressure cylinder 2. The winding component is located between opposite side walls of the frame 1 and is used to wind the tape.

[0031] like Figure 1-5As shown, in order to adaptively adjust the tension of the tape, the adjustment mechanism includes a servo motor 3, a bevel gear 4, a sleeve 5, a threaded rod 6, a bevel gear 7, a connecting plate 8, and a guide rod 9. The servo motor 3 is fixedly installed on the top of the horizontal plate. The bevel gear 4 is fixedly connected to the output end of the servo motor 3. The sleeve 5 vertically penetrates the horizontal plate and is rotatably connected to it. The bevel gear 7 is fixedly connected to the sleeve 5 and is located on the top of the horizontal plate, meshing with the bevel gear 4. The threaded rod 6 penetrates the sleeve 5 and is threadedly connected to it. The connecting plate 8 is fixedly connected to the lower end of the threaded rod 6. The lower end of the guide rod 9 is fixedly connected to the top of the connecting plate 8, and the upper end vertically penetrates the horizontal plate and is slidably connected to it. The guide rod 9 is symmetrically distributed on both sides of the sleeve 5. The guide rod 9 is T-shaped and is used to limit the sliding range of the connecting plate 8. Under the meshing transmission of the bevel gear 4 and the bevel gear 7, the sleeve 5 causes the threaded rod 6 to drive the connecting plate 8 to move vertically under the action of the guide rod 9.

[0032] The buffer connection mechanism includes a sliding column 10 and a connecting frame 11. The sliding column 10 vertically penetrates the connecting plate 8 and is slidably connected to it. It is T-shaped and symmetrically distributed at both ends of the connecting plate 8. The connecting frame 11 is fixedly connected to the lower end of the sliding column 10 and is ∩-shaped. A spring 19 is sleeved on the sliding column 10, and its two ends are fixedly connected to the connecting frame 11 and the connecting plate 8. The pressure cylinder 2 is rotatably connected between the inner walls of the connecting frame 11. The tension of the tape can be adaptively adjusted by the deformation of the spring 19 and the vertical sliding of the sliding column 10.

[0033] like Figure 1-3 As shown, the winding assembly includes a stepper motor 12, a winding drum 13, and a guide drum 14. The stepper motor 12 is fixedly installed on the outer wall of the frame 1. One end of the winding drum 13 is fixedly connected to the output end of the stepper motor 12, and the other end is rotatably connected to the inner wall of another set of frames 1. The guide drum 14 is rotatably connected between the inner walls of the frame 1, and it is symmetrically distributed relative to the cross plate.

[0034] like Figure 1 and 6 As shown, in order to make the adhesive tape bond more tightly after lamination, heating cylinders 15 are rotatably connected between the inner walls of the frame 1. Limiting rings 16 are fixedly connected to both ends of the heating cylinders 15. The diameter of the limiting rings 16 is larger than the diameter of the heating cylinders 15, which is used to limit the position of the adhesive tape. Electric heating rods 17 are fixedly connected between the inner walls of the heating cylinders 15, and heat insulation cotton 18 is glued to the inner wall of the heating cylinders 15.

[0035] In practical use, the tape is wound sequentially around the guide cylinder 14, the heating cylinder 15, and the take-up cylinder 13. Then, the electric heating rod 17 is turned on to heat the heating cylinder 15, and the heat insulation cotton 18 can reduce heat loss and ensure the heating effect of the heating cylinder 15 on the tape. Heating the tape can make the laminated tape adhere more tightly. The uniform rotation of the take-up cylinder 13 can uniformly wind up the tape. During the winding process, if it is necessary to adjust the tape tension, the servo motor 3 is turned on to make the bevel gear 4 rotate. The bevel gear 7 and the sleeve 5 rotate simultaneously, causing the threaded rod 6 to drive the pressure cylinder 2 to move down under the action of the guide rod 9. After the pressure cylinder 2 contacts the tape, it will apply elastic pressure to the tape under the action of the spring 19 and the sliding column 10, thereby adaptively adjusting the tape tension.
