[0002] The zipper assembly consists of a tape and chain teeth. The chain teeth of the plastic-steel zipper need to be arranged. After the arrangement, the plastic-steel tape needs to be punched to determine the length and punch out the excess chain teeth. Since the chain teeth are fixed in size, it is necessary to ensure that the number of teeth is accurate to ensure the consistency of the zipper length.

[0003] like Figure 1 As shown, the existing plastic steel zipper sizing machine 100' (i.e., counting device) usually adopts a tooth wheel mode to count teeth, that is, the teeth 102' of the toothed circular wheel 101' are inserted into the gaps between the teeth. However, the existing counting device is prone to missing teeth or extra teeth during actual use, resulting in inaccurate tooth counting; at the same time, when changing the tooth model, it is necessary to replace multiple accessories of the entire counting device, which is inconvenient to replace. In view of the above-mentioned problems, the inventor of this case conducted in-depth research on the problem, and thus this case was created. [Contents of the utility model]

[0007] Furthermore, it also includes an air blowing mechanism, which is arranged on the chain closing mechanism, and the blowing end of the air blowing mechanism is inserted into the chain tooth guide groove, and the air blowing mechanism is used to blow air to the chain tooth guide groove and the detection end of the opposing detector.

[0008] Furthermore, an inclined assembly hole passing through the chain tooth guide groove is obliquely provided on the chain closing mechanism, and the through-beam detector is obliquely installed on the chain closing mechanism through the inclined assembly hole.

[0014] Further, the chain closing mechanism includes an upper chain closing block and a lower chain closing block;

[0015] A support plate is arranged on one end surface of the support base, the lower chain block is locked on the support plate through a locking member, and the upper chain block is locked and connected with the lower chain block through a locking member.

[0016] Furthermore, the chain splitting structure includes a chain splitting column, which is arranged on the top surface of the other end of the supporting base, and the upper end of the chain splitting column is provided with a limiting portion for limiting the upward and downward movement of the chain teeth.

[0017] By adopting the technical solution of the utility model, at least the following beneficial effects are achieved:

[0018] 1. The chain tooth splitting and counting device is designed to include a supporting base, a chain splitting structure, a chain closing mechanism and a through-beam detector.

Therefore, features defined as "first", "second", etc. may explicitly or implicitly include one or more of the features.

[0041] See also Figures 2 to 7As shown, a preferred embodiment of a chain element splitting and counting device 100 of the utility model, the chain element splitting and counting device 100 comprises a supporting base 1, a chain splitting structure 2, a chain closing mechanism 3 and a beam detector 4, wherein the supporting base 1 is used to support the chain splitting structure 2, the chain closing mechanism 3 and the beam detector 4, the chain splitting structure 2 is used to split the zipper that is chained, the chain closing mechanism 3 is used to close the zipper after splitting, and the beam detector 4 is used to alternately detect the gaps between chain elements;

[0042] The chain splitting structure 2 and the chain closing mechanism 3 are both arranged on the supporting base 1; a chain tooth guide groove 31 is formed in the chain closing mechanism 3 for guiding the chain teeth after chain splitting to close the chain. Specifically, two chain tooth guide grooves 31 are formed in the chain closing mechanism 3, and the output ends of the two chain tooth guide grooves 31 are intersected together, so that the two rows of chain teeth after chain splitting can be guided respectively by the two chain tooth guide grooves 31, and the chain is closed at the output ends of the two chain tooth guide grooves 31; the opposing type detector 4 is installed on the chain closing mechanism 3, and the detection end of the opposing type detector 4 is aligned with the chain tooth guide groove 31. Specifically, it is only necessary to set the opposing type detector 4 on one of the chain tooth guide grooves 31, and the chain teeth passing through the chain tooth guide groove 31 and the gap between the chain teeth are alternately detected by the opposing type detector 4. In the specific implementation of the utility model, the through-beam detector 4 is equipped with a controller (such as a PLC controller) to control the through-beam detector 4 to work by using the PLC controller, and at the same time, the signal detected by the through-beam detector 4 is fed back to the PLC controller; in addition, it should be noted that the implementation procedure of using the PLC controller to control the through-beam detector 4 to work is well known to those skilled in the art and can be obtained without any creative work.

[0043] The utility model designs a chain tooth dividing and counting device 100 including a supporting base 1, a chain dividing structure 2, a chain closing mechanism 3 and a beam detector 4. The chain dividing structure 2 and the chain closing mechanism 3 are both arranged on the supporting base 1. A chain tooth guide groove 31 is formed in the chain closing mechanism 3, and the detection end of the beam detector 4 is aligned with the chain tooth guide groove 31. When working, the chain dividing structure 2 can be used to first divide the zipper, and then the beam detector 4 can be used to alternately detect the gaps between the chain teeth passing through the chain tooth guide groove 31, and finally the zipper can be closed by the chain closing mechanism 3. Compared with the traditional method of counting teeth using a tooth wheel mode, the technical solution of the utility model can effectively reduce the occurrence of missing teeth or extra teeth, thereby improving the accuracy of chain tooth counting.

[0044] In a preferred embodiment of the utility model, the chain tooth counting device 100 also includes an air blowing mechanism 5, which is arranged on the chain closing mechanism 3, and the blowing end of the air blowing mechanism 5 is inserted into the chain tooth guide groove 31, and the air blowing mechanism 5 is used to blow air to the chain tooth guide groove 31 and the detection end of the opposing detector 4 to blow away impurities such as dust in time.

[0045] Since dust and other impurities are easily attached to the detection end of the through-beam detector 4 during the actual working process, the detection accuracy of the through-beam detector 4 will be affected. Therefore, the utility model adopts a blowing mechanism 5 provided on the chain closing mechanism 3, and the blowing end of the blowing mechanism 5 is inserted into the chain tooth guide groove 31, so that the blowing mechanism 5 can be used to continuously blow air to the chain tooth guide groove 31 and the detection end of the through-beam detector 4 during the working process, so as to timely blow away the dust and other impurities in the chain tooth guide groove 31 and attached to the detection end of the through-beam detector 4, thereby preventing the through-beam detector 4 from affecting the detection accuracy due to the attachment of dust and other impurities.

[0046] In a preferred embodiment of the utility model, an inclined assembly hole 32 passing through the chain tooth guide groove 31 is obliquely provided on the chain closing mechanism 3 , and the opposing beam detector 4 is obliquely installed on the chain closing mechanism 3 through the inclined assembly hole 32 .

[0047] In actual production, the surfaces of some chain teeth (such as small-sized chain teeth) have curvature, which is not conducive to the through-beam detection by the through-beam detector 4; for this reason, the utility model adopts the method of obliquely installing the through-beam detector 4 on the chain closing mechanism 3 through the inclined assembly hole 32, which can increase the light-receiving part of the chain teeth, so that the through-beam detector 4 can detect the chain teeth more effectively, thereby further improving the accuracy of chain tooth counting.

[0048] Furthermore, in order to better increase the light receiving area of ​​the chain teeth, please refer to Figure 7 As shown, the angle α between the through-beam detector 4 and the horizontal plane is 65° to 75°. When the utility model is implemented, the angle α between the through-beam detector 4 and the horizontal plane can be any one of 65°, 67°, 70°, 62°, and 75°.

[0049] Furthermore, in order to count the chain elements better and more accurately, the opposing beam detector 4 adopts an opposing beam optical fiber sensor, and the bundle diameter of the opposing beam optical fiber sensor is 0.4-0.6 mm.

[0050] Furthermore, the detection end of the through-beam detector 4 is aligned with the middle position of the chain tooth guide groove 31. Since the chain tooth is more stable when passing through the middle position of the chain tooth guide groove 31, the utility model adopts the method of aligning the detection end of the through-beam detector 4 with the middle position of the chain tooth guide groove 31, so as to ensure the stability of the through-beam detector 4 during detection.

[0051] In a preferred embodiment of the utility model, the top wall and the bottom wall of the chain tooth guide groove 31 are formed with a clearance groove 33 at the position corresponding to the opposite-type detector 4 and the air blowing mechanism 5. Since the chain teeth after chain separation need to pass through the chain tooth guide groove 31, the utility model sets the clearance groove 33 on the top wall and the bottom wall of the chain tooth guide groove 31, which can not only play a clearance role in the installation of the air blowing mechanism 5 and the opposite-type detector 4, but also ensure that the air blowing mechanism 5 and the opposite-type detector 4 will not affect the chain teeth, thereby ensuring that the chain teeth can pass smoothly and stably through the chain tooth guide groove 31, and at the same time, the air blowing mechanism 5 can also blow air toward the opposite-type detector 4 to better blow away impurities such as dust on the opposite-type detector 4.

[0052] In a preferred embodiment of the utility model, the blowing mechanism 5 includes an upper blowing pipe 51 and a lower blowing pipe 52, and the upper surface and the lower surface of the chain closing mechanism 3 are both provided with an air pipe mounting hole 34 extending to the chain tooth guide groove 31; the upper blowing pipe 51 and the lower blowing pipe 52 are both inserted into the chain tooth guide groove 31 through the air pipe mounting hole 34, and the air outlet ends of the upper blowing pipe 51 and the lower blowing pipe 52 are formed with a bending portion 53 facing the detection end of the opposing type detector 4, so as to better realize blowing on the detection end of the opposing type detector 4. Since the through-beam detector 4 includes an upper part and a lower part, the blowing mechanism 5 of the utility model includes an upper blowing pipe 51 and a lower blowing pipe 52, and the air outlet ends of the upper blowing pipe 51 and the lower blowing pipe 52 are formed with a bending portion 53 facing the detection end of the through-beam detector 4, so that in specific use, the upper blowing pipe 51 and the lower blowing pipe 52 can be used to blow air to the upper and lower parts of the through-beam detector 4 respectively, thereby ensuring that impurities such as dust will not adhere to the detection end of the through-beam detector 4.

[0053] In the preferred embodiment of the present utility model, please refer to Figure 5 As shown, the chain closing mechanism 3 includes an upper chain closing block 35 and a lower chain closing block 36;

[0054] The end surface of one end of the support base 1 is provided with a support plate 11, the lower chain block 36 is locked on the support plate 11 through a locking member (not shown), and the upper chain block 35 is locked and connected with the lower chain block 36 through a locking member. The utility model designs the chain closing mechanism 3 to include an upper chain block 35 and a lower chain block 36, and locks the lower chain block 36 on the support plate 11 at one end of the support base 1 through a locking member, and locks the upper chain block 35 with the lower chain block 36 through the locking member, so that when the chain tooth model is replaced, it is only necessary to loosen the locking member to replace the upper chain block 35 and the lower chain block 36, and the operation is very simple, so the entire replacement and maintenance process is more convenient.

[0055] In the specific implementation of the utility model, a plurality of locking screw holes 37 are provided on the upper chain block 35, the lower chain block 36 and the support plate 11. The locking members are screws, and the screws and the locking screw holes 37 cooperate to realize the detachable connection between the lower chain block 36 and the support plate 11, and the detachable connection between the lower chain block 36 and the upper chain block 35.

[0056] In a preferred embodiment of the present invention, the chain splitting structure 2 includes a chain splitting column 21, which is arranged on the top surface of the other end of the support base 1. The upper end of the chain splitting column 21 is provided with a limiting portion 22 for limiting the upward and downward movement of the chain teeth, so as to ensure that the chain splitting column 21 can stably split the zipper. As a specific embodiment of the present invention, the limiting portion 22 is a circular ring structure.

[0057] Please refer to Figures 2 to 5 As shown, the specific working principle of the chain element counting device 100 of the present invention is as follows:

[0058] Manually grab one end of the zipper 200 (such as a plastic steel zipper), manually separate the two sides of the zipper 200, and make the chain splitting structure 2 between the two sides of the zipper; pull the zipper 200 forward, during which the chain splitting structure 2 can automatically split the zipper 200, so that the chain teeth 201 on both sides of the zipper 200 pass through the chain tooth guide grooves 31 of the chain closing mechanism 3 respectively; after the chain is closed by the chain closing mechanism 3, the closed zipper 200 is connected to a roller (not shown) equipped with a motor;

[0059] The motor is used to drive the roller to rotate, and the roller will reel in the zipper 200 after the chain is closed during the rotation. At the same time, the zipper 200 to be counted will be continuously pulled forward and automatically separated through the chain separation structure 2. When the chain teeth 201 after the chain separation pass through the chain tooth guide groove 31, the through-type detector 4 can alternately detect the gap between the chain teeth 201 and the chain teeth 202 passing through the chain tooth guide groove 31, thereby realizing the counting of the chain teeth 201.
