Abstract
Description
Technical Field
[0001] This utility model relates to the field of automatic tape cutting technology, and in particular to a convenient automatic tape cutting device. Background Technology
[0002] Adhesive tape is a tool composed of a strip-shaped substrate and an adhesive. It is mainly used for fixing, sealing, and bonding operations. In the packaging industry, adhesive tape is used to seal boxes, fix packages, and package goods. Automatic tape cutting devices can quickly and accurately cut adhesive tape in high-speed production lines. Automated equipment can also be set with different tape lengths according to different packaging needs to adapt to various product specifications.
[0003] The automatic tape cutting device includes a pinion, a connecting sliding shaft, and a guide roller. The guide roller and tension control mechanism guide the tape from the tape roll, adjust the tension to maintain stable tape delivery, detect the tape length using a sensor, activate the cutting device, and complete the cutting process. The automatic tape cutting mechanism then separates the tape. This device efficiently and accurately completes tape cutting tasks, reducing manual operation, improving work efficiency, and adapting to the needs of tapes of different lengths and specifications.
[0004] In the prior art, some automatic tape cutting devices use non-adjustable tape fixing devices to ensure the stability of the tape during the cutting process. These devices often cannot adapt to tapes of different sizes and widths. When the tape size is different, the fixing device cannot automatically adjust to the appropriate position, which will cause the tape to shift, knot, and stretch unevenly during transmission, thus affecting the cutting accuracy and efficiency. Therefore, an automatic tape cutting device is proposed to solve the above problems. Utility Model Content

The rear side of the output shaft 4 is fixedly connected to the front side of the motor 3. The external side of the output shaft 4 is rotatably connected to the inside of the vertical support plate 2. The power is transmitted to the pinion 5 through the output shaft 4. The external side of the drive assembly is fixedly connected to the pinion 5. The pinion 5 is connected to the motor 3 through the output shaft 4. The rotation drives the large gear 6 to rotate. The front side of the vertical support plate 2 is rotatably connected to the large gear 6. The pinion 5 and the large gear 6 are meshed with each other. The rear side of the large gear 6 is fixedly connected to the fixed sliding frame 7. The fixed sliding frame 7 provides a sliding track and sliding guide for the sliding support circular plate 9.
[0033] The fixed sliding frame 7 has a sliding support circular plate 9 internally connected to it. Multiple sliding support circular plates 9 can slide outwards for adjustment, supporting tapes of different sizes. A connecting sliding shaft 8 is fixedly connected to the front side of the sliding support circular plate 9. The external side of the connecting sliding shaft 8 is slidably connected to the inside of the large gear 6. The connecting sliding shaft 8 slides within the sliding hole 15 opened inside the large gear 6. The connecting sliding shaft 8 connects to the sliding support circular plate 9, driving the sliding support circular plate 9 to slide outwards. The vertical support plate 2 has a rotatably connected tape bottom paper collecting roller 10 internally. The main function of the tape bottom paper collecting roller 10 is to collect the tape. The cut adhesive tape backing paper is collected by the rotation of rollers, maintaining a clean working environment and preventing the tape backing paper from scattering. A cutting assembly is fixedly connected to the top of the base plate 1. The cutting assembly includes a fixed plate 20, the bottom of which is fixedly connected to the top of the base plate 1. A support frame 21 is fixedly connected to the top of the fixed plate 20, and a cylinder 22 is fixedly connected to the bottom of the support frame 21. A drive block 23 is slidably connected to the output end of the cylinder 22, and a cutting blade 24 is fixedly connected inside the drive block 23. The cutting assembly is the core functional part of this device, responsible for cutting the tape. The fixed plate 20 is fixedly connected to the base plate 1 at its bottom, providing sturdy support. The support frame 21 is connected to the top of the fixed plate 20 and fixes the cylinder 22. The function of the cylinder 22 is to drive the drive block 23 to slide through its output end, ultimately pushing the cutting blade 24 to precisely cut the tape.
[0034] Reference Figure 1 , Figure 2 , Figure 4 A small support plate 11 is fixedly connected to the rear side of the vertical support plate 2. The front side of the small support plate 11 is fixedly connected to the rear side of the vertical support plate 2. The small support plate 11 is used to support the cylinder 12. The cylinder 12 is fixedly connected to the front side of the small support plate 11. The cylinder 12 drives the guide roller 14 to slide left and right through the drive block 13 to adjust the tension of the conveyor belt. The output end of the cylinder 12 is slidably connected to the drive block 13. The drive block 13 is used to output the power of the cylinder 12. The front side of the drive block 13 is fixedly connected to the guide roller 14. The outside of the guide roller 14 is slidably connected to the inside of the sliding hole 15. The guide roller 14 can adjust the tension of the conveyor belt and guide the conveyor belt to move along a predetermined trajectory to prevent the conveyor belt from deviating from the path.
[0035] The vertical support plate 2 has a sliding hole 15 inside, which allows the guide roller 14 to slide freely. A motor 2 16 is fixedly connected to the rear side of the vertical support plate 2.

The output shaft 2 17 drives the rotating roller 18 to rotate. The rotating roller 18 and the follower roller 19 cooperate to drive the tape to output stably when passing through the cutting component, and can maintain consistent tension and position.
[0036] Working principle: At the start of operation, the tape fixing device is adjusted to accommodate tapes of different sizes. The motor 3 on the back of the vertical support plate 2 is started, and the output shaft 4 drives the small gear 5 to rotate, thereby driving the large gear 6 to rotate. The connecting sliding shaft 8 slides in the sliding hole 15 inside the large gear 6, which drives the sliding support plate 9 to slide in the fixed sliding frame 7. The sliding support plate 9 can slide outward to accommodate tapes of different sizes, ensuring that the tape is firmly clamped.
[0037] Once the tape is secured, cylinder 12 is activated, adjusting the position of guide roller 14 via drive block 13 to control tape tension and ensure stability during cutting. Motor 2 16 drives rotating roller 18 via output shaft 2 17. Follower roller 19 and rotating roller 18 work together to ensure smooth tape output as it passes through the cutting assembly, maintaining consistent tension and position. After the tape is ready, cylinder 22 is activated, pushing drive block 23 to precisely cut the tape with cutting blade 24, completing the tape cutting operation. After cutting, the tape backing paper is collected by tape backing paper collection roller 10, keeping the working environment clean and preventing the backing paper from scattering. Throughout the process, the device automatically adjusts the tape position and tension to ensure cutting accuracy and efficiency, ultimately achieving automatic tape cutting and convenient cutting.
