Description

Technical Field

[0001] The utility model relates to the technical field of packaging tape processing, in particular to a cutting and winding device for packaging tape. Background Art

[0002] Packaging tape, also known as BOPP tape, etc., is based on BOPP biaxially oriented polypropylene film. After uniformly applying and heating the pressure-sensitive adhesive emulsion, a glue layer with a thickness ranging from 8μm to 28μm is formed. It is an indispensable item in light industry enterprises, companies, and personal life. After the BOPP original film is treated by high-voltage corona, one surface becomes rough, and then the glue is applied on it. First, a master roll is formed, and then it is cut into small rolls with different specifications by a slitting machine, which is the tape we use daily.

[0003] In the patent with the publication number CN218342273U, a cutting and winding device for packaging tape is disclosed, including a tape cutting and winding table, a cutting and winding moving screw, a tape cutting blade, and a tape control frame. The upper end of the tape cutting and winding table is fixedly connected with a fixed support frame. Both sides of the upper end of the fixed support frame are fixedly connected with screw fixing plates. A cutting and winding moving screw is rotatably connected between the two screw fixing plates. Two cutting and winding moving nuts are threadedly connected to the outside of the cutting and winding moving screw. In the utility model, by setting the cutting and winding moving screw, the cutting and winding moving screw at the upper end position of the fixed support frame is rotated by a screw motor, so that the cutting and winding moving nut outside the cutting and winding moving screw drives the moving bracket to move. In this way, the position of the moving bracket is adjusted by the screw motor, and the position of the tape cutting blade can be adjusted, so as to cut and wind the tape at different positions on the upper end of the tape cutting and winding table, achieving the effect of simultaneously cutting and winding two groups of tapes, and accelerating the cutting and winding efficiency of the tape. However, this device has only one cutting blade. Even if it can cut and wind two groups of tapes simultaneously, the overall cutting and winding efficiency is still very low, and the position of the cutting blade cannot be adjusted according to the required size specifications of the tape, resulting in low versatility.

[0004] Based on the above situation, the utility model proposes an adjustable cutting and winding device for packaging tape. Content of the Utility Model

[0021] Embodiment 1

[0022] A cutting and winding device for packaging tape, as Figures 1 - 3As shown in the figure, it includes a base 1, a box body 2, a placement rod 21, an electric telescopic rod 3, a support frame 31, a motor 4, a protective shell 41, a rotating shaft 5, a cutting blade 6 and an adjustment mechanism. On the left side of the top of the base 1, a box body 2 is fixedly connected. At the lower part of the right side of the box body 2, a placement rod 21 is fixedly connected. On both the left and right sides of the top of the base 1, electric telescopic rods 3 that are symmetrically distributed front and back are fixedly connected. Between the output ends of two pairs of electric telescopic rods 3 that are paired front and back, a support frame 31 is fixedly connected. At the top of the right support frame 31, a motor 4 is fixedly connected. At the top of the motor 4, a protective shell 41 is fixedly connected. The right side of the box body 2 is movably connected to a rotating shaft 5. The output end of the motor 4 is fixedly connected to the rotating shaft 5 through a coupling. Axially distributed cutting blades 6 are slidably connected to the outside of the rotating shaft 5. The leftmost cutting blade 6 is fixedly connected to the rotating shaft 5. An adjustment mechanism is provided on the protective shell 41.

[0023] As Figures 1 - 3 shown, the adjustment mechanism includes a mounting frame 10, a pushing frame 11, a threaded rod 12, a sliding frame 13, a slider 14 and a connecting plate 15. A mounting frame 10 is fixedly connected to the right side of the protective shell 41. Axially distributed pushing frames 11 are movably connected to the outside of the rotating shaft 5. The pushing frame 11 is rotationally connected to the adjacent cutting blade 6. The leftmost pushing frame 11 is rotationally connected to the rotating shaft 5. The middle part of the mounting frame 10 is threadedly connected to a threaded rod 12. The threaded rod 12 is rotationally connected to the rightmost pushing frame 11. The top of the pushing frame 11 is fixedly connected to a sliding frame 13. The right sliding frame 13 is slidably connected to the protective shell 41. The leftmost sliding frame 13 is fixedly connected to the protective shell 41. Sliders 14 are slidably connected to both the front and back sides inside the sliding frame 13. Connecting plates 15 are rotationally connected between adjacent diagonally corresponding sliders 14. Adjacent connecting plates 15 are rotationally connected to each other.

[0024] As Figure 1 and Figure 3 shown, a scale is fixedly connected to the right side of the protective shell 41.

[0025] As Figure 1 and Figure 3 shown, a turning handle is fixedly connected to the right side of the threaded rod 12.

[0026] When people need to cut and roll the whole packaging tape, they can first sleeved the packaging tape on the placing rod 21, then start the motor 4 to drive the rotating shaft 5 and the cutting blade 6 to rotate. Subsequently, start the electric telescopic rod 3 to drive components such as the motor 4, the rotating shaft 5 and the cutting blade 6 to move downward and perform the cutting and rolling process on the packaging tape. After the cutting and rolling is completed, turn off the motor 4 and drive components such as the motor 4, the rotating shaft 5 and the cutting blade 6 to move upward and reset by means of the electric telescopic rod 3. If customers need packaging tapes of different specifications, they can rotate the threaded rod 12 through the turning handle before cutting and rolling, and move the threaded rod 12 left or right by an appropriate distance with the help of the scale. The left or right movement of the threaded rod 12 will drive the rightmost pushing frame 11 to move left or right. The left or right movement of the rightmost pushing frame 11 will cause the connecting plate 15 to rotate, and the slider 14 will also move towards or away from each other accordingly, so that all components except the leftmost pushing frame 11 and the cutting blade 6 move left or right, thereby adjusting the spacing between the cutting blades 6, and thus different specifications of packaging tapes meeting the requirements of customers can be cut and rolled.

[0027] Embodiment 2

[0028] On the basis of Embodiment 1, as Figure 3 and Figure 4 shown, it further includes an electric slide rail 7, a U-shaped frame 8 and a pushing plate 9.

A pushing plate 9 is fixedly connected between the tops of the two U-shaped frames 8. The pushing plate 9 is slidably connected with the placing rod 21.

[0029] After the cutting and rolling is completed, the electric slide rail 7 can be started to drive the U-shaped frame 8 and the pushing plate 9 to move to the right until the whole packaging tape is pushed out to the right, so as to quickly complete the unloading and improve the overall processing efficiency of the device. After the unloading is completed, the electric slide rail 7 can be used to drive the U-shaped frame 8 and the pushing plate 9 to move left and reset.

[0030] Embodiment 3

[0031] On the basis of Embodiment 2, as Figure 4 shown, it further includes a fixing ring 16, a top block 17 and an elastic member 18.

One end of the elastic member 18 away from the fixing ring 16 is fixedly connected with a top block 17.

[0032] When the worker moves the whole packaging tape to the left and wants to sleeve it on the placing rod 21, the packaging tape will first contact and press the top block 17, causing the upper and lower top blocks 17 to move towards each other, and the elastic member 18 is immediately compressed. When the packaging tape moves to the left and separates from the top block 17, the top block 17 moves back and resets under the action of the elastic member 18 and thereby limits and fixes the packaging tape to prevent the packaging tape from shifting during cutting and winding. After the cutting and winding are completed, when the U-shaped frame 8 and the pushing plate 9 push the packaging tape to the right, the packaging tape will first cause the two top blocks 17 to move towards each other, and the elastic member 18 is immediately compressed. After they are separated, the top block 17 moves back and resets under the action of the elastic member 18.
