[0023] Secondly, the terms "first", "second" and similar words do not indicate any order, quantity or importance, but are only used to distinguish different components, and should not be understood as a limitation on the embodiments of the present application.

[0024] In addition, the terms "mounting", "setting", "providing", "connecting", "connecting" should be broadly understood. For example, it can be fixedly connected, detachably connected, or integrally constructed; it can be mechanically connected, or electrically connected; it can be directly connected, or indirectly connected through an intermediate medium, or it can be the internal communication between two devices, elements or components.

[0025] For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0026] ​​With regard to the drawings accompanying the present application, it should be clearly understood that the drawings are for illustrative and descriptive purposes only and are not intended to limit the scope of the present specification. It should also be understood that the drawings are not drawn to scale.

[0027] Based on the patent with application number 2024201764948 of the applicant's prior application, a tassel woven tape and a weaving equipment of the tassel woven tape are disclosed. In the actual use process of the equipment, the applicant finds that it has defects. Specifically, in order to fix the blade 3 in the cutting mechanism, the needle groove 100 at the top of the needle holder 1 needs to be ground to form a sliding groove, so that the blade 3 moves in the sliding groove. Due to the fact that the hardness of the material used by the blade 3 needs to be greater than the hardness of the material used by the needle holder 1, the blade 3 is extremely easy to cause wear to the sliding groove when repeatedly moving along the sliding groove, which makes the stability of the blade 3 when moving worse, thereby affecting the cutting quality of the blade 3, and the cost of replacing the entire needle holder 1 is high, and the position of the sliding groove is relatively fixed and cannot be changed at will, which cannot adapt to the production of woven tapes of various specifications.

[0028] Based on the above problems, as shown in Figures 1 to 5 The cutting mechanism of the weaving equipment provided in the present specification includes a needle holder 1, a blade holder 2, a blade 3, and a driving mechanism. The top of the needle holder 1 is provided with a plurality of needle grooves 100 along the length direction of the needle holder 1. The needle grooves 100 are provided through along the width direction of the needle holder 1. The middle or bottom of the needle holder 1 is provided with a mounting portion. The blade holder 2 is arranged on the mounting portion. The blade holder 2 is provided with a sliding portion 200. The blade 3 is arranged in the sliding portion 200 along the width direction of the needle holder 1. The sliding portion 200 can be a groove or a channel with both ends open. The driving mechanism is used to drive the blade 3 to move along the sliding portion 200. In this way, the needle grooves 100 at the top of the needle holder 1 do not need to be ground to form a sliding groove. Instead, the blade 3 is slidably fixed on the needle holder 1 through the independent blade holder 2, thereby avoiding wear to the needle holder 1 caused by long-term and repeated movement of the blade 3, ensuring the stability of the movement of the blade 3 and the quality of the cutting. In addition, even if wear occurs, only the blade holder 2 needs to be replaced, thereby reducing the maintenance cost of the equipment.

[0029] Preferably, the hardness of the blade 3 is greater than the hardness of the needle holder 1, and the hardness of the blade holder 2 is greater than the hardness of the needle holder 1. Specifically, the hardness, toughness, and other properties of the materials used by the blade holder 2 and the blade 3 should be better than those of the material used by the needle holder 1. For example, the blade 3 and the blade holder 2 use high-speed steel, and the needle holder 1 uses ordinary steel or iron.

[0030] In some embodiments, the mounting portion is a first channel arranged in the middle of the pin seat 1, which can be machined on the pin seat 1 by wire cutting, and the first channel is matched with the tool seat 2, which is fixed in the first channel, which can be directly clamped by tight fit or connected by bolts, etc. If connected by bolts, only a connecting lug is arranged at the front end or rear end of the tool seat 2, and then fixed on the pin seat 1 by bolts.

[0031] In some embodiments, the mounting portion is arranged at the bottom of the pin seat 1, and the tool seat 2 is detachably connected to the mounting portion. Optionally, the tool seat 2 is fixed to the mounting portion by bolts.

[0032] In order to solve the problem that the position of the chute is relatively fixed and cannot be changed at will, and cannot adapt to the production of various specifications of woven belts, in some embodiments, the tool seat 2 is adjustably arranged in the mounting portion along the length direction of the pin seat 1, so that the equipment can cut different specifications of woven belts by moving the tool seat 2. There are various structures for adjustable arrangement.

[0033] Specifically, as shown in Figure 2 and Figure 4 If the mounting portion is a second channel 4 arranged in the middle of the pin seat 1, and the width of the second channel 4 is greater than the width of the pin seat 1, an adjusting assembly 5 is arranged, which includes a first wedge-shaped block 50 and a second wedge-shaped block 51. The tool seat 2 is abutted and fixed in the second channel 4 by the first wedge-shaped block 50 and the second wedge-shaped block 51. The first wedge-shaped block 50 and the second wedge-shaped block 51 are both flat on one side and have matching inclined surfaces on the other side. Thus, the first wedge-shaped block 50 and the second wedge-shaped block 51 abutting the two inclined surfaces are embedded in the second channel 4, so that the tool seat 2 is clamped in the second channel 4. At the same time, due to the cooperation of the two inclined surfaces, the width of the two flat surfaces can also be adjusted, so that the second channel 4 of different widths can be adapted.

[0034] Further, the adjusting assembly 5 also includes an adjusting block 52, which abuts and fixes the tool seat 2 in the second channel 4 by the adjusting block 52, the first wedge-shaped block 50 and the second wedge-shaped block 51. It should be understood that the width and number of the adjusting block 52 are adjusted according to the actual situation. The cooperation of the adjusting block 52, the first wedge-shaped block 50 and the second wedge-shaped block 51 can further expand the application range of the equipment.

[0035] For example, the mounting portion is arranged at the bottom of the pin seat 1, and the tool seat 2 is detachably connected to the mounting portion. Then a threaded hole is arranged on the tool seat 2, and a long circular hole is arranged on the pin seat 1 along the length direction, and then locked and fixed at the required position by a fastener.

[0036] In some embodiments, a transmission rod 6 is arranged between the driving mechanism and the blade 3, a slide rail 7 is arranged at the rear of the pin seat 1 along the sliding direction of the blade 3, and a sliding block 8 is arranged on the transmission rod 6 and matched with the slide rail 7. Since the blade 3 needs to be moved repeatedly and quickly, the structure of the slide rail 7 and the sliding block 8 can effectively reduce the wear of the equipment and prolong the service life of the equipment.

[0037] In some embodiments, a fixing portion is arranged on the transmission rod 6 close to one end of the blade 3, and a locking bolt 9 for fixing the blade 3 is arranged on the fixing portion. In this way, the blade 3 is convenient to disassemble and assemble.

[0038] Specifically, the blade 3 includes a blade portion 30 at the front end and a body portion 31 at the rear end. Generally, the overall length of the blade 3 is slightly longer, so that after the blade portion 30 is damaged, the blade portion 30 can be reprocessed on the body portion 31 for secondary use. Secondly, the fixing portion is a slot 10 arranged at the front end of the transmission rod 6. The slot 10 can be arranged penetratingly or closed at the rear end. The slot 10 is matched with the body portion 31. The locking bolt 9 is at least two. The fixing portion is provided with a threaded hole not less than the number of the locking bolts 9. The locking bolt 9 is threadedly connected to the threaded hole and abuts against the body portion 31 to fix the body portion 31.
