Description

Technical Field

[0001] The utility model belongs to the technical field of zipper processing, and more specifically, particularly relates to a polishing mechanism for plastic tooth zippers. Background Technique

[0002] After the plastic tooth zipper is formed by a row of teeth machine, there are some burrs or flash on the middle surface of its inner side, that is, the parting surface during mold opening, which affects the appearance and use of the plastic zipper. Therefore, it is necessary to use a polishing mechanism to process it.

[0003] The existing Chinese patent application number is: CN202122409706.1, which discloses a polishing device for plastic teeth of a zipper. It includes a fixed plate and a pressing belt plate. The pressing belt plate is installed above the fixed plate, and a belt passing channel for the zipper chain belt to pass through is formed between the pressing belt plate and the fixed plate. One side of the pressing belt plate is provided with a rotatable polishing wheel. The polishing wheel is located at the tangential position of the belt passing channel and abuts against the inner side of the teeth in the belt passing channel. The zipper chain belt passes through the belt passing channel between the pressing belt plate and the fixed plate to form a limit on the zipper chain belt. The polishing wheel cuts off the burrs and flash on the inner side of the teeth and makes them fall off, improving the quality and appearance of the zipper. This technical solution discloses the polishing treatment of plastic teeth, but does not perform subsequent detection on the teeth, making it difficult to timely discover the tooth missing phenomenon that occurs during injection molding and polishing, and it is difficult to ensure the production quality.

[0035] As shown in the Figure 1 to the Figure 7 accompanying drawings:

[0036] The utility model provides a polishing mechanism for rubber teeth zippers, which comprises a fixed bottom plate 1. Feeding mechanisms 5 and traction mechanisms 4 are respectively installed at two ends of the fixed bottom plate 1. A polishing mechanism 2 is installed on the top of the fixed bottom plate 1. A detection and marking mechanism 3 is also installed on the top of the fixed bottom plate 1 between the polishing mechanism 2 and the traction mechanism 4. The polishing mechanism 2 comprises a base 201 fixedly installed on the top of the fixed bottom plate 1. A lifting plate 202 is installed directly above the base 201. Two groups of grinding wheels 207 are installed at the bottom of the lifting plate 202. Two groups of lower covers 205 are fixedly installed on the top of the base 201. Upper covers 206 cover the tops of the two groups of lower covers 205. A moving groove for the zipper tape to pass through is correspondingly arranged on the bottom side of the upper cover 206 and the top side of the lower cover 205. Two groups of arc-shaped notches 2015 for the rubber teeth of the zipper to expose are arranged on one side of the moving groove. The arc-shaped notches 2015 are opposite to the side surfaces of the grinding wheels 207. The detection and marking mechanism 3 comprises a fixed seat 301 fixedly installed on the top of the fixed bottom plate 1. A cylinder 303 is vertically installed on the top of the fixed seat 301 through a mounting plate 302. A punch rod 304 is vertically and fixedly installed at the telescopic end of the bottom of the cylinder 303. A zipper combining lower plate 305 is fixedly installed on the fixed seat 301 directly below the punch rod 304. A zipper combining upper plate 306 is fixedly installed on the top of the zipper combining lower plate 305. Laser detectors 308 are installed on the zipper combining upper plate 306 and the zipper combining lower plate 305 at one end close to the polishing mechanism 2 through mounting brackets 307 respectively.

[0037] Among them, the feeding mechanism 5 comprises a vertically arranged guide rail 501. One end of the guide rail 501 is fixedly installed on one side of the fixed bottom plate 1 through a connecting plate 503. One end of the connecting plate 503 is fixedly installed with a support arm 504. A slider 502 is slidably installed on one side of the guide rail 501. Mounting shafts 505 are horizontally installed on the same side of the slider 502, the connecting plate 503 and the support arm 504. Two groups of guide wheels 506 are rotatably installed on the outer sides of the mounting shafts 505. The three mounting shafts 505 are installed in a V shape.

[0038] Among them, proximity switches 507 are installed at both the upper and lower ends of the guide rail 501; a counterweight is fixedly connected to the bottom side of the slider 502, so as to detect the zipper tape when the zipper tape is fed after being arranged on the guide pulley 506. Specifically, when the injection speed of the tape arranging machine is less than the running speed of the polishing mechanism 2, the zipper tape will drive the slider 502 to move upward along the guide rail 501. When it moves upward to the proximity switch 507 above the guide rail 501, the proximity switch 507 will be triggered at this time. The proximity switch 507 sends a pause instruction to the externally connected control host, and at this time, the traction mechanism 4 and the polishing mechanism 2 will be paused. At the same time, the tape arranging machine continues to inject, and the zipper tape will become longer. At this time, the slider 502 and the counterweight at its bottom will move downward along the guide rail 501 under the action of gravity. When it moves downward to the proximity switch 507 below the guide rail 501, the proximity switch 507 will be triggered at this time. The proximity switch 507 sends a working instruction to the externally connected control host, and at this time, the traction mechanism 4 and the polishing mechanism 2 will be started. In this way, the feeding of the zipper tape can be well controlled.

[0039] Among them, the traction mechanism 4 includes a vertical plate 401 fixedly installed on the top of the fixed base plate 1 and a driving motor three 405. A U-shaped frame 403 is slidably installed on one side of the vertical plate 401. A clamping wheel 404 is installed inside the U-shaped frame 403 through a shaft. The top end of the U-shaped frame 403 is used to connect the connection head of the driving part. The driving part can be a cylinder, and the position of the U-shaped frame 403 can be flexibly adjusted during use to press the zipper for driving; a driving wheel 402 is fixedly installed at the output shaft of the driving motor three 405 directly below the clamping wheel 404, so as to drive the zipper tape to move quickly in cooperation with the clamping wheel 404.

[0040] Among them, optical axes 203 are vertically and fixedly installed at the four corners of the top of the base 201. Guide sleeves 204 are slidably sleeved on the outer sides of the optical axes 203. The top ends of the guide sleeves 204 are fixedly connected to the lifting plate 202. Through holes for the top ends of the optical axes 203 to pass through are provided at the four corners of the lifting plate 202; a first spring 2014 is sleeved on the outer side of the optical axis 203, and the upper and lower ends of the first spring 2014 are respectively abutted against the guide sleeve 204 and the base 201.

[0041] Among them, a driving motor one 209 is fixedly installed at the top end of the lifting plate 202 through a bracket. The grinding wheels 207 are vertically arranged, and the top end of its central axis passes through the lifting plate 202 and is symmetrically located on one side of the driving motor one 209; synchronous wheels 208 are fixedly sleeved at the output end of the driving motor one 209 and the top end of the central axis, and the synchronous wheels 208 are connected by a synchronous belt for driving the two grinding wheels 207 to rotate synchronously.

[0042] Among them, a second driving motor 2010 is fixedly installed on one side of the base 201, and the output shaft of the second driving motor 2010 is horizontally arranged and fixedly connected with an eccentric wheel 2011. One side of the eccentric wheel 2011 is in sliding contact with the bottom side of the lifting plate 202. Since the base 201 and the devices installed on its top have a certain self-weight, it can always ensure that its bottom side is always in contact with the eccentric wheel 2011, so that when the eccentric wheel 2011 rotates, it can drive the lifting plate 202 to move up and down, so as to realize that while the grinding wheel 207 rotates, it can move up and down to comprehensively polish the zipper teeth.

[0043] Among them, the two ends of the two lower covers 205 are connected by a light rod 2013, and through holes slidably connected with the light rod 2013 are arranged at the ends of the lower covers 205. Both ends of the light rod 2013 are rotatably connected with fixing blocks 2012, and the fixing blocks 2012 are fixedly connected with the base 201; Spring two 2016 is sleeved on both ends of the light rod 2013, and both ends of the spring two 2016 are respectively abutted against the fixing block 2012 and the lower cover 205. Through the cooperation of the light rod 2013 and the spring two 2016, the lower cover 205 can be driven to press the zipper tightly against the grinding wheel 207 to achieve efficient grinding and polishing.

[0044] Among them, chain combining upper plates 306 and chain combining lower plates 305 are correspondingly provided with chain combining grooves at their bottom sides and top sides, and the chain combining grooves are Y-shaped; Detection through holes are arranged inside the chain combining grooves, and the detection ends of the laser detectors 308 are respectively located at one ends of the detection through holes, so as to quickly detect whether there are missing teeth in the zipper. The laser detectors 308 are commercially available Xinshe Electric XS-HD10.

[0045] Among them, a convex block is arranged on one side of the fixed seat 301, and a through hole vertically penetrating its bottom side is arranged on the top side of the convex block. The punching rod 304 is slidably installed in the through hole of the convex block to improve the smoothness of the punching rod 304 during operation, which is beneficial to punching the corresponding position of the zipper cloth bag when the laser detector 308 detects missing teeth, so that production personnel can discover and handle it in time.

[0046] Working principle of this embodiment: During use, by installing the detection and marking mechanism 3 on one side of the polishing mechanism 2, rapid detection can be achieved after polishing the zipper teeth. When missing teeth are found, punching operations can be performed on the tape of the zipper, facilitating subsequent inspection by the staff to improve product quality. At the same time, through the coordinated use of the upper chain closing plate 305 and the lower chain closing plate 306 in the detection and marking mechanism 3, the zipper after polishing can be quickly closed, which is beneficial to improving the integrity of the product; through the cooperation of the eccentric wheel 2011 and the lifting plate 202 in the polishing mechanism 2, when the grinding wheel 207 rotates, the grinding wheel 207 can be driven up and down to comprehensively grind and polish the zipper teeth, with relatively high grinding and polishing quality; through the settings of the guide rail 501, the slider 502 and the proximity switch 507 in the feeding mechanism 5, rapid detection can be carried out when the zipper tape is fed to prevent the zipper from being strained or broken.
