Description

Technical Field

[0001] The utility model belongs to the technical field of magic tape slot templates, and particularly relates to an adaptive magic tape slot template. Background Art

[0002] Most of the magic tapes purchased on the current market have different widths due to production process problems. Even the same roll of magic tape may have different widths. For example, some magic tapes marked as 2 cm wide are actually measured to be 1.9 - 2.3 cm wide. When the existing automatic feeding magic tape template encounters magic tapes with different widths, if the magic tape is too wide, it cannot be fed in, and if it is too narrow, the magic tape is likely to fall off after the pressing frame is lifted. Only by loosening the screws on the width adjustment locking piece to adjust the width of the magic tape slot can automatic sewing be achieved, and the adjustment is relatively frequent, which is time-consuming and laborious. For this reason, the utility model provides an adaptive magic tape slot template. Summary of the Utility Model

[0003] The purpose of the utility model is to provide an adaptive magic tape slot template to solve the problems raised in the above background art.

[0004] To achieve the above purpose, the utility model provides the following technical scheme: an adaptive magic tape slot template, including a template base and a width adjustment base. Rear clamping strips and front clamping strips are relatively arranged inside the template base. A magic tape slot is formed between the rear clamping strip and the front clamping strip. The rear clamping strip is elastically telescopically connected to the width adjustment base through an elastic member. The front clamping strip is elastically telescopically connected to one end inside the template base through an elastic member. A magic tape is elastically clamped inside the magic tape slot. The width adjustment base and the template base slide and adjust the width of the magic tape slot through a guiding sliding member. A width adjustment locking piece for locking the sliding of the width adjustment base is further arranged between the width adjustment base and the template base.

[0005] Preferably, the elastic member is a compression spring, and multiple compression springs are provided. Grooves are respectively opened at opposite ends of the rear clamping strip and the front clamping strip for clamping the magic tape to prevent the magic tape from falling off.

[0006] Preferably, the guiding sliding member includes an installation guiding groove arranged on the template base and a guiding block integrally arranged on the width adjustment base. The guiding block extends into the installation guiding groove for guiding and limiting sliding.

[0007] Preferably, the width adjustment locking piece is located outside the guiding block, and both ends of the width adjustment locking piece lock the guiding block and the template base through locking screws.

[0008] Preferably, on one side of both the rear clamping strip and the front clamping strip connected to the compression spring, there are protrusions, and on the protrusions, there are round hole grooves for connecting the compression spring. In order to stably install the compression spring, both the template base and the width adjustment base are provided with retraction grooves matching the protrusions.

[0009] Compared with the prior art, the beneficial effects of the present utility model are as follows: The self - adaptive width template of the present utility model determines the basic width by adjusting the width adjustment base. When the magic tapes with different widths are sent into the magic tape card slot, the width can be automatically adjusted by the compression springs on the front and rear clamping strips, and the magic tapes can be clamped. Moreover, due to the clamping of the compression springs, the magic tapes are not easy to fall off, so that automatic sewing can be realized for both wide and narrow magic tapes; there is no need to adjust the magic tape card slot, and the front clamping strip can also be disassembled, only the rear clamping strip is retained, and in cooperation with the retraction groove on one side, it is applicable to magic tapes with wider widths, greatly improving the work efficiency and easily sewing the magic tapes.
