Detailed Description

The present invention will be further described with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.

As shown in fig. 1 to 4, a nylon zipper tooth counting mechanism of a zipper sizing and tooth removing machine comprises a bottom plate 1, an upper cover plate 2 and a tooth counting device 3, wherein a zipper guide groove 4 is formed between the upper cover plate 2 and the bottom plate 1, a tooth dividing part is arranged on the zipper guide groove 4 and used for temporarily increasing the interval between zipper teeth 1501 of a zipper chain 15, the upper cover plate 2 is provided with a viewing port 5, the viewing port 5 is positioned above the tooth dividing part, and the tooth counting device 3 is arranged above the viewing port 5.

The zipper tooth counting mechanism 111 of the sizing and tooth removing machine is generally arranged between the chain feeding mechanism 222 of the sizing and tooth removing machine and the tooth removing mechanism 333 of the sizing and tooth removing machine. When the zipper is used, the zipper chain 15 penetrates through the zipper guide groove 4 between the upper cover plate 2 and the bottom plate 1, and the zipper teeth 1501 of the zipper teeth device 3 moving through the zipper guide groove 4 are counted by the zipper teeth device 3 positioned above the observation opening 5 through the observation opening 5. The tooth counting device 3 is an electronic device, generally adopts a laser sensor, is in data connection with a control system of the sizing tooth removing machine, when the counting reaches a set number, the drag chain mechanism 444 of the sizing tooth removing machine stops, and the tooth removing mechanism 333 of the sizing tooth removing machine performs sizing tooth removing on the zipper chain 15. Due to the accurate counting of the teeth counting device 3, it is ensured that the tooth removing mechanism 333 keeps the same interval and length between each small section of the slide fastener formed after the removal of the teeth of the fastener chain 15. Since the interval between the teeth 1501 of the fastener chain 15 is very small in the conventional state and the counting means 3 cannot sense the passing of the teeth 1501 for counting, it is necessary to provide the teeth dividing portion on the chain guide groove 4 so that the interval between the teeth 1501 at the sensing position of the counting means 3 is temporarily increased to facilitate the counting of the counting means 3.

As a preferable structure of the chain guide groove, referring to fig. 3-4, the middle part of the chain guide groove 4 is provided with a guide post 401 and the outlet of the chain guide groove 4 is provided with a narrowing position 403, so that the chain guide groove 4 forms a structure similar to a zipper slider, the zipper chain 15 is firstly separated during the passing of the chain guide groove 4, then the separated two ends are closed, then the arc-shaped protrusion 402 on one side of the chain guide groove 4 and the position of the guide post 401 close to the arc-shaped protrusion 402 are provided with a notch 404 to form a tooth separating part of the zipper tooth counting mechanism, and the part of the zipper chain 15 passing through the arc-shaped protrusion 402 is expanded in an arc shape, thereby achieving the purpose of temporarily increasing the interval between the zipper teeth 1501.

As a preferred structure of a zipper tooth counting mechanism, referring to fig. 2, one side of an upper cover plate 2 and one side of a bottom plate 1 are connected through a rotating shaft 6 and can be opened and closed manually at any time, when a zipper chain 15 is penetrated and arranged for the first time, the upper cover plate 2 is turned to open a zipper guide groove 4, the zipper chain 15 is placed in the zipper guide groove 4, and a lock catch 7 is arranged on the other side of the upper cover plate 2 and the other side of the bottom plate 1 opposite to the rotating shaft 6, so that the upper cover plate 2 and the bottom plate 1 are fixedly covered. Specifically, the lock catch 7 comprises a rotatable lock rod 701 and a lock body 702 having a groove for placing the lock rod 701, the lock rod 701 is disposed on the bottom plate 1, the lock body 702 is disposed on the upper cover plate 2, and the lock rod 701 is rotated into the groove of the lock body 702 to lock the lock catch 7. And the groove of the lock body 702 is also provided with an adjusting screw 703 for adjusting the locking tightness of the lock catch 7.

As a preferable structure of the zipper tooth counting mechanism, referring to fig. 2, a first zipper pressing device 8 is provided at an outlet of the zipper guide groove 4. When the drag chain mechanism 444 of the sizing tooth removing machine stops, the distance between the drag chain mechanism 444 and the zipper tooth counting mechanism 111 is far, the braking effect of the drag chain mechanism 444 cannot necessarily guarantee timely braking of the zipper chains 15 in the zipper guide grooves 4, and the zipper chains 15 in the zipper guide grooves 4 move forwards due to inertia, so that the false counting of the tooth counting device 3 can be caused. Therefore, the first chain pressing device 8 is provided, and the first chain pressing device 8 completely presses the fastener chain 15 at the exit of the chain guide groove 4 while the drag chain mechanism 444 is stopped, and the fastener chain 15 is stopped from moving further due to the influence of inertia.

Specifically, the first zipper pressing device 8 comprises a first zipper pressing block 801 and a zipper pressing cylinder 802, the bottom plate 1 is provided with an opening 101, the first zipper pressing block 801 is located in the opening 101, the bottom of the first zipper pressing block is connected with the zipper pressing cylinder 802, and the zipper chain 15 is clamped between the first zipper pressing block 801 and the upper cover plate 2 by opening the zipper pressing cylinder 802 to move the first zipper pressing block 801 upwards. Or the upper cover plate 2 is provided with the upper zipper pressing block 803, and the zipper chain 15 is clamped through the action of the first zipper pressing block 801 and the upper zipper pressing block 803, so that the upper cover plate 2 is prevented from being directly impacted by the first zipper pressing block 801.

As a preferable structure of the zipper tooth counting mechanism, referring to fig. 2, a slide rail 9 is provided at the bottom of the bottom plate 1, and the bottom plate 1 can move left and right on the slide rail 9.
