[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the attached drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] In order to enable those skilled in the art in this technical field to better understand the solution of the present utility model, the present utility model will be further described in detail below in conjunction with the attached drawings and specific embodiments.

[0026] Please refer to the attached Figure 1 As shown: A high-precision zipper tooth pitch monitoring device is applied to a zipper sewing device to detect the chain tooth pitch during the sewing process. The zipper sewing device includes a frame and a sewing machine disposed on the frame. It is characterized in that the high-precision zipper tooth pitch monitoring device includes a bracket 1, a first metering component 2, and a second metering component 3. The bracket 1 is a support bracket welded by hollow square steel, used to provide support for the installation of the first metering component 2 and the second metering component 3, and then quickly dock it at the output end of the zipper sewing device; the first metering component 2 is disposed on the top of the bracket 1 and is used to count the number of chain teeth passing by; the second metering component 3 is located on one side of the first metering component 2 and is used to measure the moving distance of the zipper tape. When in use, the left and right zippers sewn by the zipper sewing machine pass through the first metering component in sequence to measure the number of chain teeth moving within the unit time, and then the second metering component measures the moving distance of the zipper tape within the same time. By whether the ratio between the moving distance of the zipper tape and the number of chain teeth is within the set error range, the operation of the zipper sewing device is monitored in real time, thereby achieving the final consistency of the zipper tooth pitch and ensuring the precise mutual splicing of nylon zippers.

[0027] On the basis of the above embodiments, the output end of the first metering component 2 and the input end of the second metering component 3 are on the same horizontal line and are also on the same straight line as the output end of the zipper sewing device. In this way, during zipper sewing, vibration during the working process can be effectively reduced, which affects the sewing effect and the metering effect, and the detection accuracy can be improved.

[0028] On the basis of the above embodiments, the first metering component 2 includes: a first metering base 21, a jig element 22, and a counting and amplifying component 23. The first metering base 21 is detachably arranged on the bracket 1 to provide support for the installation of the jig element 22 and the counting and amplifying component 23; the jig element 22 is rotatably arranged on the top of the first metering base 21 to ensure that the pitch of all teeth is balanced and consistent when counting by the counting and amplifying component 23, thereby improving the metering accuracy; the counting and amplifying component 23 is rotatably arranged on the jig element 22, and one end of the counting and amplifying component 23 extends above the contact surface between the first metering base 21 and the jig element 22 to measure the number of chain teeth passing through per unit time and amplify the signal for accurate counting. During operation, the counting and amplifying component 23 rotatably arranged on the first metering base 21 will move with the movement of the zipper. During the movement, one end of the counting gear on the counting and amplifying component 2 extends above the contact surface between the first metering base 21 and the jig element 22, so that there will be no relative slip with the zipper during detection. Therefore, the number of teeth passed by the zipper can be accurately calculated, providing a guarantee for subsequent detection. Of course, in other embodiments, the first metering component 2 can also be an industrial camera or other rotating mechanical structures, which are not specifically limited here.

[0029] Through the above technical solutions, the utility model can improve the metering accuracy: the first metering base 21 provides stable support for the fixture element 22 and the counting and amplifying component 23, ensuring the firm installation and working stability of each component. This helps to reduce the metering errors caused by equipment shaking or component loosening. For example, in the production of zippers with high precision requirements, accurate metering can ensure the quality consistency of each batch of products. It can optimize the metering precision: the fixture element 22 is rotatably arranged on the top of the first metering base 21 to correct the alignment of the zipper, ensuring that the spacing of all tooth pitches is balanced and consistent when the counting and amplifying component 23 counts. This design can significantly improve the metering precision. For example, when making zippers for high-end clothing, precise metering can ensure that the length and quality of the zippers meet strict design standards. It can enhance the stability of signal detection: the counting and amplifying component 23 is rotatably arranged on the fixture element 22, and one end extends above the contact surface, avoiding relative sliding with the zipper and being able to accurately calculate the number of teeth passed by the zipper. During the rapid production of zippers, stable signal detection can ensure the accuracy of counting, regardless of the production speed. It can adapt to diverse requirements: the first metering component 2 is not limited to a specific structure and can also be an industrial camera or other rotating mechanical structures, which increases its adaptability to different production scenarios and requirements. For example, for zippers of different materials or special specifications, the most suitable metering method can be flexibly selected. It can guarantee the quality of subsequent inspections: accurate metering results provide a reliable guarantee for subsequent inspections, helping to detect product quality problems in advance and reducing the flow of defective products into the market. For example, in the quality inspection link of zippers, based on accurate metering data, products that do not meet the requirements can be screened out in a timely manner, improving the overall product qualification rate. It can improve production efficiency: precise metering and stable working performance reduce production interruptions and rework caused by metering errors, thus effectively improving production efficiency. Taking a large-scale zipper production factory as an example, an efficient metering process can shorten the production cycle of products and meet the large market demand. Moreover, it can reduce production costs: by improving metering precision and accuracy, the waste of raw materials and the cost of defective product treatment caused by metering errors are reduced. For example, the overuse of raw materials or product scrapping caused by inaccurate metering of zipper length is avoided.

[0030] Based on the above embodiments, the counting and amplifying component 23 includes a first rotating shaft rotatably arranged on the first metering base 21; a metering gear is detachably arranged at one end of the first rotating shaft, and an amplification coding disk is arranged at the other end; a U-shaped sensor is arranged on the circumferential side of the rotation of the amplification coding disk; the metering gear extends to the fixture element 22.

[0031] Based on the above embodiments, the second metering component 3 includes a second metering base 31; a length measuring component 32 is rotatably arranged on the second metering base 31; a pressing component 33 can approach or move away from the length measuring component 32 above it.

[0032] Based on the above embodiments, the length measuring assembly 32 includes a material pulling rotating shaft rotatably arranged on the second metering base 31; a driving motor is provided at one end of the material pulling rotating shaft, and a second sensor is provided at the other end; protruding portions are circumferentially and arrayed on the circumferential side of the material pulling rotating shaft.

[0034] In summary: The first metering assembly and the second metering assembly of the present utility model cooperate online synergistically to effectively achieve online detection, and the error between adjacent teeth can be controlled within the range of ±0.01 mm, effectively ensuring the consistency of the zipper tooth pitch.
