Description

Technical Field

[0001] The invention relates to the technical field of zipper production, and in particular to a device and method for detecting color fastness of a zipper. Background Art

[0002] A zipper is composed of chain teeth, a slider, upper and lower stops (front stop and rear stop) or a locking piece, among which the chain teeth are the key part, which directly determines the side pull strength of the zipper. Generally, a zipper has two chain belts, each of which has a row of chain teeth, and the two rows of chain teeth are arranged alternately. In the production process of zippers, it is necessary to test the color fastness of zippers. Put the zipper to be tested on the workbench, and move the test cloth through the reciprocating structure to make the test cloth and the zipper form friction, and then observe the color change of the zipper after friction, and then complete the color fastness test of the zipper. The overall operation is simple; However, in the actual detection process, the friction between the detection cloth and the zipper can only form a friction detection effect on the surface of the zipper, and cannot be used for other positions of the zipper, such as: the locking piece and the pull ring on the outside of the locking piece, the side of the chain away from each other, between the chain teeth, etc. The detection effect is general, and the traditional detection device can only complete the detection of the color fastness of the zipper, the function is relatively single, and it cannot detect the connection effect of the zipper.

[0007] Preferably, an extrusion assembly for extruding the zipper is installed on the outside of the movable frame, and the extrusion assembly includes two oblique grooves opened on the side wall of one of the first friction plates, and sliding rods are slidably connected in the two oblique grooves, and a fixed plate is slidably connected to the outside of the sliding rod, and the fixed plate is fixedly connected to the movable frame.

[0010] Preferably, the third connecting rod and the fourth connecting rod are both arranged in the shape of regular polygons.

[0011] A method for detecting the color fastness of a zipper comprises the following steps: S1. Place the chain to be tested on the placement board and fix the chain; S2, start the motor to drive the first friction plate to move back and forth to rub the chain; S3. When the motor is started, the outer surface, side wall and tooth gap of the chain can be rubbed at the same time, and the connection effect between the chains can be tested; S4. Turn off the motor, remove the chain, and compare the color change of the position after the chain is rubbed, thereby completing the color fastness test of the chain.

[0012] The beneficial effects of the present invention are: 1. First, in the process of color fastness detection of the zipper, the motor is started to drive the first friction plate to move back and forth, and the first friction plate rubs the surface of the zipper chain, and then the color of the chain surface after friction is compared, so as to complete the detection operation of the color fastness of the chain surface. In this process, under the action of the threaded cylinder, the movable ring, the pull ring, and the clamp ring will move back and forth as a whole, so that the pull ring moves back and forth relative to the locking member to form friction, and the color change of the friction point between the pull ring and the locking member after friction is observed, so as to complete the color fastness detection operation of the pull ring and the locking member. In the above working process, the second friction plate is always against the surface of the pull ring, which can form a friction effect on the pull ring, and then the color fastness detection operation of the pull ring surface can be completed, and finally the color fastness detection of more different positions of the zipper is completed, rather than being limited to the color fastness detection of the zipper chain surface, so as to achieve multiple goals at one stroke. 2. During the movement of the moving frame, the moving frame drives the first connecting plate to move up and down, and the first connecting plate is always against the outer wall of the zipper, thereby forming a friction effect on the outer wall of the zipper. At the same time, the first connecting plate also drives the third friction plate to move, and the third friction plate is against the inner wall of the adjacent chain tooth to form a friction effect on the inner wall of the chain tooth, and finally the color fastness detection operation of the inner wall of the chain tooth can be completed; 3. At the same time, the moving frame will also drive the extrusion plate to move. The extrusion plate and the zipper will resist each other, which will form a certain extrusion on the connected chain belts, causing the chain belts on both sides to move away from each other. During this process, if the connection effect of the chain belts on both sides is good, no change will occur. If the chain belts on both sides are disconnected, it means that the connection effect of the chain belts is worse, thereby completing the detection operation of the chain belt connection effect.

Secondly, the zipper to be tested is placed on the placement plate 8, and the threaded rod 9 is rotated. Under the limiting effect of the seventh connecting rod 10, the rotating threaded rod 9 drives the clamping plate 6 to move towards the zipper until the clamping plate 6, the zipper and the placement plate 8 are tightly abutted against each other, thereby completing the clamping and fixing operation of the zipper. At this time, the hydraulic rod 7 is started, and the hydraulic rod 7 drives the placement plate 8 and the zipper to move upward as a whole until the zipper and the first friction plate 13 are in contact with each other. The plates 13 abut against each other, at this time, the motor 2 is started, and under the limiting effect of the bracket 4 and the slide plate 12, the mounting tube 44, the clamping ring 11 and the mounting ring 5 are driven to move back and forth relative to the workbench 1, and the clamping ring 11 drives the first friction plate 13 to move back and forth, and the first friction plate 13 and the zipper abut against each other to form a friction operation on the zipper surface. After a period of time, the motor 2 is turned off, the zipper is removed, and the color change of the zipper is observed, thereby completing the detection operation of the color fastness of the zipper. The above are all existing technologies and no redundant description is made; like Figure 3 , Figure 4 , Figure 5 , Figure 7 , Figure 8A pull ring shaking assembly is installed in the mounting ring 5, and the pull ring shaking assembly includes a threaded cylinder 14 slidably installed on the side wall of the mounting ring 5, a connecting ring 23 is fixedly connected to the outer side of the threaded cylinder 14, a first spring 24 is fixedly connected between the connecting ring 23 and the mounting ring 5, a rotating cylinder 15 is threadedly connected to the outer side of the threaded cylinder 14, the rotating cylinder 15 and the mounting ring 5 are rotatably connected, and a gear 39 is fixedly connected to the outer side of the rotating cylinder 15, a rack 41 is slidably connected to the side wall of one of the first friction plates 13, the rack 41 and the gear 39 are meshed, a sixth connecting rod 40 is fixedly connected to the side wall of the rack 41, and a movable Ring 18, the side wall of the other first friction plate 13 is slidably connected with a first connecting rod 20, a fifth spring 38 is fixedly connected between the first connecting rod 20 and the first friction plate 13, a clamp ring 19 is fixedly connected to the outer side of the first connecting rod 20, a second connecting rod 21 is slidably connected to the lower side of the threaded cylinder 14, a sixth spring 42 is fixedly connected between the second connecting rod 21 and the threaded cylinder 14, a moving frame 16 is fixedly connected to the lower side of the second connecting rod 21, a second friction plate 17 is fixedly connected to the side wall of the moving frame 16, a positioning rod 43 is fixedly connected to the side wall of the bracket 4, and a plurality of retaining rings 45 are evenly fixedly connected to the outer side of the positioning rod 43; First, a standard fabric for detecting the color fastness of the zipper is also fixedly installed on the outer side of the second friction plate 17. Secondly, during the rotation of the reciprocating screw 3, the mounting ring 5 will be driven to move back and forth as a whole through the mounting tube 44 and the eighth connecting rod 46, wherein the upper side of the threaded tube 14 is arranged in an arc shape, and the mounting ring 5 is sleeved on the outer side of the positioning rod 43. During the movement of the mounting ring 5 back and forth, the lower side of the positioning rod 43 is flat, which can increase the contact surface between the threaded tube 14 and the positioning rod 4. Therefore, when the threaded tube 14 is always in contact with the surface of the positioning rod 43, the first spring 24 is always in a stable compression. When the threaded tube 14 and the retaining ring 45 are in contact with each other, it will cause the threaded tube 14 to move up and down relative to the mounting ring 5. The threaded cylinder 14 drives the connecting ring 23 to move up and down (in this process, although the threaded cylinder 14 and the rotating cylinder 15 are threadedly connected, there is no self-locking phenomenon, that is, the thread lead angle is greater than the equivalent friction angle). Then, before the color fastness test of the zipper is performed, the clamp ring 19 is pressed first to move the sixth connecting rod 40 out of the hole in the clamp ring 19, and the pull ring on the outside of the zipper locking member is put on the sixth connecting rod 40. The clamp ring 19 is loosened. Under the action of the fifth spring 38, the clamp ring 19, the pull ring, and the moving ring 18 are always tightly against each other, and the fifth spring 38 is always in a compressed state. In this process, the compressed fifth spring 38 will apply a rightward force (with a force of 1 / 400mm) to the first connecting rod 20 and the clamp ring 19. Figure 8, based on the direction of rotation), the clamp ring 19 drives the rack 41 to move rightward through the sixth connecting rod 40, so the rack 41 has a tendency to drive the gear 39 to rotate, and the gear 39 has a tendency to drive the rotating cylinder 15 to rotate. Since the rotating cylinder 15 and the threaded cylinder 14 are threadedly connected, the rotating rotating cylinder 15 has a tendency to drive the threaded cylinder 14 to move. If the threaded cylinder 14 moves, the connecting ring 23 will stretch the first spring 24, but the first spring 24 is always in a compressed state in this solution, that is, the elastic force of the compressed first spring 24 is always greater than the elastic force of the compressed fifth spring 38, so the compressed fifth spring 38 does not drive the rack 41 to move, and then in the process of color fastness testing of the zipper, during the threaded cylinder 14 Under the action, the rotating cylinder 15 will be caused to rotate back and forth all the time, and the rotating cylinder 15 drives the movable ring 18, the pull ring, and the clamping ring 19 to move back and forth as a whole through the gear 39 and the rack 41, so that the pull ring moves back and forth relative to the locking member to form friction. After a period of time, the color change of the friction point between the pull ring and the locking member after friction can be observed, thereby completing the color fastness detection operation of the connection between the pull ring and the locking member, and in the above-mentioned working process, the second friction plate 17 is always against the surface of the pull ring, and in the process of the movable frame 16 moving up and down, the movable frame 16 drives the second friction plate 17 to move up and down through the sixth spring 42, and the second friction plate 17 and the pull ring are against each other, which can form a friction effect on the pull ring, thereby completing the color fastness detection operation of the pull ring surface.

[0016] like Figure 6 , a detection component for the outer surface of the zipper teeth is installed in the moving frame 16, and the detection component includes a third connecting rod 25 slidably installed on both sides of the moving frame 16, two third connecting rods 25 are located on one side of the moving frame 16 and are fixedly connected to a first connecting plate 27, a second spring 26 is fixedly connected between the first connecting plate 27 and the moving frame 16, two second connecting plates 28 are fixedly connected to the side wall of the first connecting plate 27, a fourth connecting rod 29 is fixedly connected between the two second connecting plates 28, a third connecting plate 30 is slidably sleeved on the outer side of the fourth connecting rod 29, a third spring 31 is fixedly connected between the third connecting plate 30 and the second connecting plate 28, a third friction plate 32 is fixedly connected to the lower side of the third connecting plate 30, and the third connecting rod 25 and the fourth connecting rod 29 are both regular polygonal arrangements; First, standard fabrics for testing the color fastness of the zipper are fixedly installed on the outer sides of the first connecting plate 27 and the third friction plate 32. Secondly, before the zipper is fixed, the third connecting rod 25 is pulled away from each other. The third connecting rod 25 drives the first connecting plate 27 to move as a whole. The first connecting plate 27 compresses the second spring 26 until the distance between the two first connecting plates 27 is greater than the width of the zipper. After the zipper is fixed, the third connecting rod 25 is released. Under the action of the second spring 26, the first connecting plate 27 and the outer wall of the zipper are abutted. When the moving frame 16 follows the mounting ring 5 to move back and forth as a whole, the moving frame 16 will also drive the first connecting plate 27 to move left and right. The first connecting plate 27 moves back and forth, and in the process of the moving frame 16 moving up and down relative to the mounting ring 5, the moving frame 16 will also drive the first connecting plate 27 to move up and down. However, in the process of the first connecting plate 27 following the moving frame 16 to move, the first connecting plate 27 always abuts against the outer side wall of the zipper, thereby forming a friction effect on the outer side wall of the zipper, and in the process of the first connecting plate 27 following the moving frame 16 to move up and down, the third friction plate 32 will not always be located between adjacent chain teeth, that is, in the process of the third friction plate 32 following the first connecting plate 27 to move downward, the third friction plate 32 extends into the gap between adjacent chain teeth and abuts against the chain teeth, thereby forming a friction effect on the chain teeth, thereby stretching or compressing the third spring 31, so as to Figure 6 Based on the direction, when the first connecting plate 27 moves to the right as a whole, when the third friction plate 32 extends into between adjacent chain teeth, under the obstruction of the chain teeth, the third friction plate 32 stops following the first connecting plate 27 to move to the right, thereby compressing the third spring 31 on the left and stretching the third spring 31 on the right, until the first connecting plate 27 drives the third friction plate 32 to move upward and the third friction plate 32 moves out from between two adjacent chain teeth. At this time, under the action of the third spring 31, the third friction plate 32 returns to its original position relative to the first connecting plate 27, thereby causing the third friction plate 32 and the inner wall of the adjacent chain tooth to abut against each other during the movement of the first connecting plate 27 to form a friction effect on the inner wall of the chain tooth, and finally the color fastness detection operation on the inner wall of the chain tooth can be completed.

[0017] like Fig. 9 , an extrusion assembly for the zipper is installed on the outer side of the moving frame 16, and the extrusion assembly includes two oblique grooves 33 opened on the side wall of one of the first friction plates 13, a slide bar 34 is slidably connected in the two oblique grooves 33, a fixed plate 37 is slidably connected to the outer side of the slide bar 34, the fixed plate 37 is fixedly connected to the moving frame 16, a fifth connecting rod 35 is also slidably connected to the outer side of the slide bar 34, an extrusion plate 22 is fixedly connected to the lower side of the fifth connecting rod 35, and a fourth spring 36 is fixedly connected between the extrusion plate 22 and the slide bar 34; First, during the up and down movement of the moving frame 16, the moving frame 16 drives the fixing plate 37 to move up and down. Since the fixing plate 37 is slidably connected to the slide bar 34 and under the restriction of the inclined groove 33, the slide bar 34 moves along the direction of the inclined groove 33 as a whole. Fig. 9 Based on the direction, the left slide bar 34 moves as a whole in the lower left direction, and the right slide bar 34 moves as a whole in the lower right direction. The slide bar 34 drives the extrusion plate 22 to move. The extrusion plate 22 and the zipper are against each other, which will form a certain extrusion on the connected chain belts, so that the chain belts on both sides move away from each other. During this process, if the connection effect of the chain belts on both sides is good, no change will occur. If the chain belts on both sides are disconnected, it means that the connection effect of the chain belts is worse, thereby completing the detection operation of the chain belt connection effect.

[0018] A method for detecting the color fastness of a zipper comprises the following steps: S1. Place the chain to be tested on the placement plate 8 and fix the chain; S2, start the motor 2 to drive the first friction plate 13 to move back and forth to rub the chain; S3. When starting the motor 2, the outer surface, side wall and tooth gap of the chain can be rubbed at the same time, and the connection effect between the chains can be detected; S4, turn off the motor 2, remove the chain, compare the color change of the position after the chain is rubbed, and then complete the detection of the color fastness of the chain.

[0019] In the present invention, the zipper to be tested is placed on the placement plate 8, and the threaded rod 9 is rotated. Under the limiting action of the seventh connecting rod 10, the rotating threaded rod 9 drives the clamping plate 6 to move in the direction close to the zipper until the clamping plate 6, the zipper and the placement plate 8 are tightly abutted, thereby completing the clamping and fixing operation of the zipper. At this time, the hydraulic rod 7 is started, and the hydraulic rod 7 drives the placement plate 8 and the zipper to move upward as a whole until the zipper and the first friction plate 13 abut against each other. At this time, the motor 2 is started, and under the limiting action of the bracket 4 and the slide plate 12, the mounting cylinder 44, the clamping ring 11 and the mounting ring 5 are driven to move back and forth relative to the workbench 1 as a whole. The clamping ring 11 drives the first friction plate 13 to move back and forth left and right, and the first friction plate 13 and the zipper abut against each other to form a friction operation on the surface of the zipper. After a period of time, the motor 2 is turned off, the zipper is removed, and the color change of the zipper is observed, thereby completing the detection operation of the color fastness of the zipper. The above are all existing technologies and no unnecessary elaboration is made. During the rotation of the reciprocating screw 3, the mounting ring 5 is driven to move back and forth as a whole through the mounting tube 44 and the eighth connecting rod 46, wherein the upper side of the threaded tube 14 is set in an arc shape, and the mounting ring 5 is sleeved on the outside of the positioning rod 43. During the movement of the mounting ring 5 back and forth, the lower side of the positioning rod 43 is flat, which can increase the contact surface between the threaded tube 14 and the positioning rod 4. Therefore, when the threaded tube 14 is always against the surface of the positioning rod 43, the first spring 24 is always in a stable compression. When the threaded tube 14 and the retaining ring 45 are against each other, the threaded tube 14 will move up and down relative to the mounting ring 5, and the threaded tube 14 will drive the connecting ring 23 to move up and down (In this process, although the threaded cylinder 14 and the rotating cylinder 15 are threadedly connected, there is no self-locking phenomenon, that is, the thread lead angle is greater than the equivalent friction angle). Then, before the color fastness test of the zipper is performed, the clamp ring 19 is pressed first to move the sixth connecting rod 40 out of the hole in the clamp ring 19, and the pull ring on the outside of the zipper locking member is put on the sixth connecting rod 40. The clamp ring 19 is loosened. Under the action of the fifth spring 38, the clamp ring 19, the pull ring, and the moving ring 18 are always tightly against each other, and the fifth spring 38 is always in a compressed state. In this process, the compressed fifth spring 38 will exert a rightward force (with a force of 1 / 400mm) on the first connecting rod 20 and the clamp ring 19. Figure 8 , based on the direction of rotation), the clamp ring 19 drives the rack 41 to move rightward through the sixth connecting rod 40, so the rack 41 has a tendency to drive the gear 39 to rotate, and the gear 39 has a tendency to drive the rotating cylinder 15 to rotate. Since the rotating cylinder 15 and the threaded cylinder 14 are threadedly connected, the rotating rotating cylinder 15 has a tendency to drive the threaded cylinder 14 to move. If the threaded cylinder 14 moves, the connecting ring 23 will stretch the first spring 24, but the first spring 24 is always in a compressed state in this solution, that is, the elastic force of the compressed first spring 24 is always greater than the elastic force of the compressed fifth spring 38, so the compressed fifth spring 38 does not drive the rack 41 to move, and then in the process of color fastness testing of the zipper, during the threaded cylinder 14 Under the action, the rotating cylinder 15 will rotate back and forth all the time, and the rotating cylinder 15 drives the moving ring 18, the pull ring, and the clamping ring 19 to move back and forth as a whole through the gear 39 and the rack 41, so that the pull ring moves back and forth relative to the locking member to form friction. After a period of time, the color change of the friction point between the pull ring and the locking member after friction can be observed, thereby completing the color fastness detection operation of the connection between the pull ring and the locking member, and in the above-mentioned working process, the second friction plate 17 is always against the surface of the pull ring. In the process of the moving frame 16 moving up and down, the moving frame 16 drives the second friction plate 17 to move up and down through the sixth spring 42, and the second friction plate 17 and the pull ring are against each other, which can form a friction effect on the pull ring, thereby completing the color fastness detection operation of the pull ring surface; Before the zipper is fixed, the third connecting rod 25 is first pulled away from the other side, and the third connecting rod 25 drives the first connecting plate 27 to move as a whole, and the first connecting plate 27 compresses the second spring 26 until the distance between the two first connecting plates 27 is greater than the width of the zipper. After the zipper is fixed, the third connecting rod 25 is released. Under the action of the second spring 26, the first connecting plate 27 and the outer side wall of the zipper are abutted. In the process of the moving frame 16 following the overall left and right movement of the mounting ring 5, the moving frame 16 will also drive the first connecting plate 27 to move back and forth left and right, and the moving frame 16 moves up and down relative to the mounting ring 5. During the movement, the moving frame 16 will also drive the first connecting plate 27 to move up and down. However, in the process of the first connecting plate 27 following the moving frame 16 to move, the first connecting plate 27 always contacts the outer side wall of the zipper, thereby forming a friction effect on the outer side wall of the zipper, and in the process of the first connecting plate 27 following the moving frame 16 to move up and down, the third friction plate 32 will not always be located between adjacent chain teeth, that is, in the process of the third friction plate 32 following the first connecting plate 27 to move downward, the third friction plate 32 extends into the gap between adjacent chain teeth and contacts the chain teeth, thereby forming a friction effect on the chain teeth, thereby stretching or compressing the third spring 31, so as to prevent the third friction plate 32 from being stuck in the gap between adjacent chain teeth and the chain teeth. Figure 6 Based on the direction, when the first connecting plate 27 moves rightward as a whole, when the third friction plate 32 extends into between adjacent chain teeth, under the obstruction of the chain teeth, the third friction plate 32 stops following the first connecting plate 27 to move rightward, thereby compressing the third spring 31 on the left and stretching the third spring 31 on the right, until the first connecting plate 27 drives the third friction plate 32 to move upward, and the third friction plate 32 moves out from between two adjacent chain teeth. At this time, under the action of the third spring 31, the third friction plate 32 returns to its original position relative to the first connecting plate 27, thereby causing the third friction plate 32 and the inner wall of the adjacent chain tooth to abut against each other during the movement of the first connecting plate 27 to form a friction effect on the inner wall of the chain tooth, and finally the color fastness detection operation on the inner wall of the chain tooth can be completed; In the process of the moving frame 16 moving up and down, the moving frame 16 drives the fixed plate 37 to move up and down. Since the fixed plate 37 is slidably connected to the slide bar 34 and under the restriction of the inclined groove 33, the slide bar 34 moves along the direction of the inclined groove 33 as a whole. Fig. 9 Based on the direction, the left slide bar 34 moves as a whole in the lower left direction, and the right slide bar 34 moves as a whole in the lower right direction. The slide bar 34 drives the extrusion plate 22 to move. The extrusion plate 22 and the zipper are against each other, which will form a certain extrusion on the connected chain belts, so that the chain belts on both sides move away from each other. During this process, if the connection effect of the chain belts on both sides is good, no change will occur. If the chain belts on both sides are disconnected, it means that the connection effect of the chain belts is worse, thereby completing the detection operation of the chain belt connection effect.
