Description

Technical Field

[0001] The present invention relates to the technical field of zipper disassembly, and in particular to a zipper disassembly device and a zipper disassembly method using the zipper disassembly device. Background Art

[0002] Recycling and regeneration are effective solutions to environmental pollution in environmental protection. Zippers, as common commodities in our daily life, have the value of recycling and regeneration.

[0003] Usually, if Figure 1 As shown, the zipper 80 includes a pair of cloth tapes 81 distributed on the left and right, a chain belt fixed at the inner edge of each cloth tape 81, a pull head 83 installed on the chain belt, an upper stopper 84 distributed at one end of the chain belt and fixed to the cloth tape 81, and a lower stopper 85 distributed at the other end of the chain belt and fixed to the cloth tape 81. The chain belt is composed of a row of chain teeth 82. The left and right chain belts are engaged and constitute a chain belt 86. The cloth tape 81 and the chain belt 86 extend forward and backward along the length direction of the zipper 80. The pull head 83 is slidably installed on the chain belt 86. The upper stopper 84 and the lower stopper 85 prevent the pull head 83 from detaching from the chain belt 86. Each chain tooth 82 in the chain belt can be a metal chain tooth, a resin chain tooth, or a nylon chain tooth. Therefore, the zipper 80 has diversity in composition structure and material, and each component of the zipper 80 must be disassembled before recycling and regeneration.

[0004] At present, the zipper splitting device in the prior art can realize the automatic separation of the cloth tape and the chain tape, but the slider, the upper stop and the lower stop need to be separated manually, which is not only cumbersome to operate, but also reduces the efficiency of zipper splitting and recycling. In addition, when manually separating the upper stop and the lower stop, workers must use a cutter to manually cut off the cloth tape and the chain tape near the upper stop and the lower stop. Due to manual cutting, debris is easily generated during the cutting process. The splashed debris is stained on the cloth tape, the cutter, or the parts of the equipment, which not only increases the impurity content of the cloth tape during the regeneration stage, but also reduces the life of the cutter and causes equipment failure. Summary of the invention

[0005] In view of the above-mentioned shortcomings of the prior art, the technical problem to be solved by the present invention is to provide a zipper splitting device which can automatically split the entire zipper.

[0006] To achieve the above-mentioned object, the present invention provides a zipper disassembling device, which includes an end separation mechanism and a belt separation mechanism;

[0007] The end separation mechanism comprises an end cutting unit and a slider card plate, wherein the end cutting unit comprises a cutting support base plate and a first cutter movable toward or away from the cutting support base plate, wherein the slider card plate is distributed on one side of the end cutting unit along the direction in which the zipper is pulled out of the end cutting unit, and wherein a slider stop groove is arranged in the slider card plate, wherein the slider stop groove allows the cloth tape and the chain tape of the zipper to pass through;

[0008] The belt separation mechanism includes a separation support base plate, a pair of rotatable conveying rollers for pressing the cloth belt, and a pair of second cutters for cutting the cloth belt. The separation support base plate and the pair of conveying rollers are arranged side by side along the thickness direction of the zipper, and a separation channel is formed between the two. The separation channel allows the cloth belt and the chain belt to pass through. The pair of second cutters are arranged on the inner side of the pair of conveying rollers along the width direction of the zipper.

[0009] In the above-mentioned zipper splitting device, the upper stop part and the lower stop part of the zipper are cut by the first cutter of the end cutting unit, so as to realize the automatic separation of the upper stop part and the lower stop part; after the upper stop part is cut off, in the process of pulling the zipper out of the end cutting unit, the slider clamps the slider between the end cutting unit and the slider clamp, and only allows the cloth tape and the chain tape to be pulled out, so as to realize the automatic separation of the slider; thereafter, the rest of the zipper is moved into the separation channel of the belt separation mechanism, and while the conveying roller conveys this part of the zipper forward, the second cutter separates the cloth tape and the chain tape of this part of the zipper, so as to realize the automatic separation of the cloth tape and the chain tape. Therefore, the present application can automatically split the whole zipper, and split it into the upper stop recovery part, the lower stop recovery part, the slider recovery part, the cloth tape recovery part and the chain tape recovery part, so as to effectively improve the efficiency of zipper splitting and recycling. In addition, when the end cutting unit automatically cuts off the upper stop part and the lower stop part of the zipper, it can reduce the generation of debris, thereby reducing the amount of debris contamination on the tape and the end cutting unit, which is beneficial to the recycling of the tape and reduces the occurrence rate of end cutting unit failure.

[0010] Furthermore, the zipper splitting device also includes a fixed machine base, upper and lower stop recovery boxes, a slider recovery box, a tape recovery box, and a chain tape recovery box, and the end separation mechanism and the tape separation mechanism are both installed on the machine base; the machine base is provided with upper and lower stop recovery channels, a slider recovery channel, a tape recovery channel and a chain tape recovery channel, one end of the upper and lower stop recovery channels extends to the cutting support bottom plate, and the other end is connected to the upper and lower stop recovery boxes, one end of the slider recovery channel extends to one side of the slider card plate toward the end cutting unit, and the other end is connected to the slider recovery box, one end of the tape recovery channel extends to the separation channel, and the other end is connected to the tape recovery box, one end of the chain tape recovery channel extends to the separation channel, and the other end is connected to the chain tape recovery box.

[0011] In the process of automatically disassembling the whole zipper, the upper stop recovery part and the lower stop recovery part cut off by the end cutting unit enter the upper and lower stop recovery boxes through the upper and lower stop recovery channels, the slider recovery part separated by the slider card enters the slider recovery box through the slider recovery channel, the cloth tape recovery part separated by the tape separation mechanism enters the cloth tape recovery box through the cloth tape recovery channel, and the chain tape recovery part separated by the tape separation mechanism enters the chain tape recovery box through the chain tape recovery channel. In this way, the present application realizes the classified recycling of each split part after the whole zipper is disassembled, further improving the efficiency of zipper disassembly and recycling.

[0012] Preferably, the zipper disassembling device further comprises an exhaust fan and an exhaust duct, and the exhaust fan is connected to the tape recovery channel through the exhaust duct. There are no metal parts and resin parts on the tape part separated from the whole zipper, so the tape part has a light weight; after the exhaust fan and the exhaust duct are configured, a suction force for sucking the tape part can be generated in the tape recovery channel, and the tape part separated by the tape separation mechanism can be accurately sucked into the tape recovery channel, thereby ensuring the reliability of classified recovery of the tape part.

[0013] Preferably, the upper and lower stop recovery channels, the slider recovery channel and the chain belt recovery channel are all inclined channels extending obliquely downward. The upper stop part, the lower stop part, the slider and the chain belt part separated from the whole zipper have metal parts or resin parts, so that these parts have a certain self-weight, so these parts will automatically slide downward along the upper and lower stop recovery channels, the slider recovery channel and the chain belt recovery channel under the action of their own weight, until they fall into the upper and lower stop recovery boxes, the slider recovery box and the chain belt recovery box distributed in a one-to-one correspondence with the upper and lower stop recovery channels, the slider recovery channel and the chain belt recovery channel, thereby realizing reliable classification and recovery of each part at a low cost.

[0014] Furthermore, the end cutting unit also includes a cutting support frame and a cutting drive source, the cutting support base plate is fixed to the cutting support frame, the first cutter is reciprocatingly mounted on the cutting support frame along the thickness direction of the zipper, the cutting drive source is mounted on the cutting support frame and is transmission-connected to the first cutter, driving the first cutter to reciprocate in a direction approaching or away from the cutting support base plate, thereby cutting off the upper stopper portion and the lower stopper portion of the zipper.

[0015] Preferably, a third cutter is fixedly disposed on the cutting support bottom plate, and the first cutter and the third cutter are arranged opposite to each other in the thickness direction of the zipper and can engage with each other. In this way, the first cutter constitutes an upper cutter distributed on the front side of the zipper, and the third cutter constitutes a lower cutter distributed on the back side of the zipper, which can more reliably cut the upper stopper part and the lower stopper part of the zipper.

[0016] Furthermore, along the width direction of the zipper, one end of the slider stop groove penetrates to the side of the slider card plate. In this way, when the zipper is placed in the end cutting unit, the zipper can be placed in the slider stop groove at the same time, and the slider on the zipper is placed between the end cutting unit and the slider card plate.

[0017] Furthermore, the tape separation mechanism further comprises an ultrasonic generator, the second cutter is an ultrasonic cutter, and the ultrasonic generator is connected to the ultrasonic cutter. The ultrasonic cutting method is adopted to cut the tape, the cutting is accurate and reliable, and the quality of the cut surface of the tape can be ensured.

[0018] Furthermore, the tape separation mechanism also includes a spacing adjustment mechanism, which acts on a pair of second cutters to change the spacing between the pair of second cutters in the zipper width direction, and is suitable for separating zippers of different specifications and sizes.

[0019] Furthermore, the belt separation mechanism also includes a separation support frame, a rotating shaft rotatably supported in the separation support frame, and a transmission drive source, wherein the transmission drive source is in transmission connection with the rotating shaft, and a pair of transmission rollers are detachably mounted on the rotating shaft. When the transmission drive source drives the rotating shaft to rotate, the pair of transmission rollers rotate synchronously with the rotating shaft to drive the cloth belt forward; and the transmission rollers are a detachable mounting structure for easy maintenance.

[0020] Furthermore, the belt separation mechanism also includes a clamping mechanism, a clamping mounting plate movably mounted on the clamping mechanism, at least one pair of clamping wheels rotatably mounted on the clamping mounting plate, and at least one pair of supporting wheels rotatably mounted on the separation support frame. The clamping mechanism is connected to the clamping mounting plate to drive the clamping mounting plate to move in a direction close to or away from the rotating shaft. Each pair of clamping wheels and each pair of supporting wheels are arranged vertically opposite to each other and rotatably matched on the outer peripheral side of the rotating shaft. After the clamping mechanism drives the clamping mounting plate to move in a direction close to the rotating shaft, the clamping wheel presses the rotating shaft against the supporting wheel, which accordingly causes the transmission roller to be reliably pressed against the cloth belt, thereby ensuring the reliability of the transmission roller in moving the cloth belt forward.

[0021] The present application also provides a zipper disassembly method for disassembling a zipper, wherein the zipper comprises a pair of fabric tapes, chain teeth fixed to the inner edges of the pair of fabric tapes, a slider, an upper stopper, and a lower stopper, wherein the chain teeth are engaged to form a chain tape, the slider is mounted on the chain tape, and the upper stopper and the lower stopper are respectively arranged at both ends of the chain tape along the length direction of the chain tape and are both fixed to the fabric tape; the zipper disassembly method uses the zipper disassembly device as described above, and the zipper disassembly method comprises the following steps:

[0022] S1, placing one end of the zipper with the upper stopper on the cutting support base plate, and passing the cloth tape and chain tape of the zipper through the slider stopper groove of the slider clamping plate, and the first cutter moves in a direction close to the cutting support base plate to cut off a part of the zipper end with the upper stopper; then, the zipper is pulled out of the end cutting unit and the slider stopper groove, and the first cutter is reset;

[0023] S2, placing one end of the zipper with the lower stopper on the cutting support base plate, and passing the cloth tape and chain tape of the zipper through the slider stopper groove of the slider clamping plate, and the first cutter moves in a direction close to the cutting support base plate to cut off a part of the zipper end with the lower stopper; then, the zipper is pulled out of the end cutting unit and the slider stopper groove, and the first cutter is reset;

[0024] S3. In the above step S1 or the above step S2, in the process of pulling the zipper out of the end cutting unit and the slider stop groove, the slider installed on the zipper chain is stopped by the slider clamping plate, so that the slider is detached from the zipper chain;

[0025] S4, sending the zipper processed in step S3 into the separation channel of the belt separation mechanism, a pair of conveying rollers drives the zipper to move, and at the same time, a pair of second cutting knives cuts the cloth tape to separate the cloth tape and the chain tape.

[0026] As described above, the zipper disassembly device and method according to the present invention have the following beneficial effects:

[0027] In the present application, the upper stop part and the lower stop part of the zipper are cut by the first cutter of the end cutting unit, so as to realize the automatic separation of the upper stop part and the lower stop part; after the upper stop part is cut off, in the process of pulling the zipper out of the end cutting unit, the slider clamps the slider between the end cutting unit and the slider clamp, and only allows the cloth tape and the chain tape to be pulled out, so as to realize the automatic separation of the slider; after that, the rest of the zipper is moved into the separation channel of the belt separation mechanism, and while the conveying roller conveys this part of the zipper forward, the second cutter separates the cloth tape and the chain tape of this part of the zipper, so as to realize the automatic separation of the cloth tape and the chain tape. Therefore, the present application can automatically split the whole zipper, split it into the upper stop recovery part, the lower stop recovery part, the slider recovery part, the cloth tape recovery part and the chain tape recovery part, and effectively improve the efficiency of zipper splitting and recycling. In addition, when the end cutting unit automatically cuts off the upper stop part and the lower stop part of the zipper, it can reduce the generation of debris, thereby reducing the amount of debris contamination on the tape and the end cutting unit, which is beneficial to the recycling of the tape and reduces the occurrence rate of end cutting unit failure.

[0131] In addition, the descriptions of "first", "second", etc. in this application are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0132] The present application provides a zipper splitting device and a zipper splitting method using the zipper splitting device, which are used to split the entire zipper 80. For ease of description, in the following embodiments, the definitions of the directions are as follows: the length direction of the zipper 80 is defined as the front-to-back direction, the width direction of the zipper 80 is defined as the left-to-right direction, and the thickness direction of the zipper 80 is defined as the up-down direction; and when the slider 83 of the zipper 80 is pulled forward, the zipper 80 is closed; when the slider 83 of the zipper 80 is pulled backward, the zipper 80 is opened. Based on this, Figure 1 In the view shown, the left side and the right side of the paper are the left direction and the right direction respectively, the upper side and the lower side of the paper are the front direction and the rear direction respectively, and the front side and the back side of the paper are the upper direction and the lower direction respectively.

[0133] like Figure 1As shown, the zipper 80 includes a pair of cloth tapes 81 arranged side by side, chain teeth 82 fixed to the inner edges of the pair of cloth tapes 81, a slider 83, an upper stopper 84, and a lower stopper 85. The multiple chain teeth 82 on each cloth tape 81 form a row of chain tapes extending forward and backward. The chain teeth 82 are engaged with the slider 83 to form a chain tape 86. The slider 83 can be slidably mounted on the chain tape 86. When the slider 83 is pulled forward, the chain tape 86 is closed; when the slider 83 is pulled backward, the chain tape 86 is opened. Along the length direction of the chain tape 86, the upper stopper 84 is arranged at the front end of the chain tape 86 and fixed to the cloth tape 81, and is used to limit the front limit position of the slider 83 to prevent the slider 83 from detaching forward from the chain tape 86; the lower stopper 85 is arranged at the rear end of the chain tape 86 and fixed to the cloth tape 81, and is used to limit the rear limit position of the slider 83 to prevent the slider 83 from detaching backward from the chain tape 86.

[0134] like Figures 2 to 4 As shown, the zipper splitting device involved in the present invention includes an end separation mechanism 10 and a belt separation mechanism 20, the end separation mechanism 10 is used to separate the upper stop part, the lower stop part and the slider 83 of the zipper 80, and the belt separation mechanism 20 is used to separate the cloth tape part and the chain tape part of the zipper 80.

[0135] Specifically, if Figure 2 and Figure 6 As shown, the end separation mechanism 10 includes an end cutting unit 30 and a slider card plate 40. The end cutting unit 30 includes a cutting support base plate 31 and a first cutter 32 that can move toward or away from the cutting support base plate 31. The upper stopper part and the lower stopper part of the zipper 80 are cut off by the reciprocating motion of the first cutter 32. Fig.16a and Fig.16b As shown; after cutting, the zipper 80 is pulled out from the end cutting unit 30 backward along its length direction. The slider card 40 is distributed on the rear side of the end cutting unit 30 along the direction in which the zipper 80 is pulled out from the end cutting unit 30, and a slider stop groove 41 that passes through the front and back is provided in the slider card 40. In the up and down direction, the width of the slider stop groove 41 is configured to be smaller than the minimum thickness of the slider 83, but larger than the thickness of the cloth tape 81 and the thickness of the chain tape 86, so that the slider stop groove 41 only allows the cloth tape 81 and the chain tape 86 of the zipper 80 to pass through, but does not allow the slider 83 of the zipper 80 to pass through. In this way, after the end cutting unit 30 completes the cutting operation, when the zipper 80 is pulled backward from the end separation mechanism 10, the slider card 40 stops the slider 83 between the end cutting unit 30 and the slider card 40; as the zipper 80 is completely pulled out, the slider 83 is naturally separated from the chain belt 86 of the zipper 80, as shown in FIG. Fig.16a shown.

[0136] like Figures 10 to 12 ,as well as Fig.14and Fig.15 As shown, the belt separation mechanism 20 includes a separation support base plate 21, a pair of rotatable conveying rollers 22 for pressing the cloth belt 81, and a pair of second cutters 23 for cutting the cloth belt 81. The pair of conveying rollers 22 and the separation support base plate 21 are arranged side by side in the thickness direction of the zipper 80, and a separation channel is formed between the two. The separation channel allows the cloth belt 81 and the chain belt 86 of the zipper 80 to pass through. The separation channel is a channel extending forward and backward and penetrating, and the rear end port of the separation channel constitutes a feed port 212. The two conveying rollers 22 are arranged side by side in the width direction of the zipper 80, and the two second cutters 23 are arranged side by side in the width direction of the zipper 80; and the pair of second cutters 23 are distributed on the inner side of the pair of conveying rollers 22 in the width direction of the zipper 80. When the conveying roller 22 rotates, the cloth belt 81 is driven to move forward. During this process, the second cutter 23 cuts the cloth belt 81 below it. When the zipper 80 that has entered the separation mechanism has all passed through the conveying roller 22 and the second cutter 23, the cloth belt part and the chain belt part of the zipper 80 are automatically separated. Fig.16c shown.

[0137] The present application also provides a zipper disassembly method using the zipper disassembly device, comprising the following steps:

[0138] Step 1, place one end of the entire zipper 80 into the end separation mechanism 10: you can first place the upper stop part at the front end of the zipper 80 and cut off the upper stop part first; or you can first place the lower stop part at the rear end of the zipper 80 and cut off the lower stop part first. The following description takes the upper stop part at the front end of the zipper 80 as an example. After placing the front end of the entire zipper 80 into the end separation mechanism 10, place the front end part of the zipper 80 with the upper stop 84 on the cutting support base plate 31, so that the slider 83 of the zipper 80 is located between the end cutting unit 30 and the slider card plate 40, and at the same time, the cloth tape 81 and the chain tape 86 of the zipper 80 are both inserted into the slider stop groove 41 of the slider card plate 40. The first cutter 32 moves in the direction close to the cutting support base plate 31, as shown in FIG. Fig.16a As shown, the first cutter 32 cuts the portion of the front end of the zipper 80 having the upper stopper 84 along the cutting line L1, and the cut upper stopper portion is defined as the upper stopper recovery portion 91. The first cutter 32 moves away from the cutting support bottom plate 31 and resets.

[0139] Step 2: Pull the zipper 80 backward from the end cutting unit 30 and the slider stop groove 41, and the slider stop groove 41 stops the slider 83 on the chain belt 86; when the zipper 80 is completely pulled backward from the slider stop groove 41, the slider 83 is automatically separated from the chain belt 86, and the separated slider 83 is defined as the slider recovery part 92, and the remaining part of the zipper 80 after cutting off the upper stop part and separating the slider 83 is defined as the first intermediate split part 96. Since the slider 83 moves forward relative to the chain belt 86 during the process of being separated from the chain belt 86, in the first intermediate split part 96 after the slider 83 is separated, the chain belt 86 is in a closed state, and the rear end of the chain belt 86 is the lower stop 85 fixed on the cloth belt 81.

[0140] Step 3: After placing the first intermediate split piece 96 into the end separation mechanism 10, the rear end portion of the zipper 80 with the lower stopper 85 is placed on the cutting support base plate 31, and the cloth tape 81 and the chain tape 86 of the zipper 80 are both inserted into the slider stop groove 41 of the slider clamping plate 40. The first cutter 32 moves in a direction close to the cutting support base plate 31, such as Fig.16b As shown, the first cutter 32 cuts off the portion of the rear end of the zipper 80 with the lower stop 85 along the tangent line L2, and the lower stop portion to be cut off is defined as the lower stop recovery portion 93, and the remaining portion of the first intermediate split piece 96 after the lower stop portion is cut off is defined as the second intermediate split piece 97. Afterwards, the second intermediate split piece 97 of the zipper 80 is pulled out backward from the end cutting unit 30 and the slider stop groove 41; the first cutter 32 moves in a direction away from the cutting support bottom plate 31 and resets. The second intermediate split piece 97 only includes the fabric tape 81 and the chain belt 86 of the zipper 80, and the chain belt 86 is in a closed state.

[0141] Step 4: The second intermediate split piece 97 of the zipper 80 processed in step 3 is fed forward into the separation channel through the feed port 212 of the belt separation mechanism 20; a pair of conveying rollers 22 rotate to drive the second intermediate split piece 97 of the zipper 80 to move forward. Fig.16c As shown, the left second cutter 23 of the pair of second cutters 23 cuts the left cloth tape 81 along the tangent line L3, and the right second cutter 23 of the pair of second cutters 23 cuts the right cloth tape 81 along the tangent line L4. After the pair of conveying rollers 22 drive all the second middle split pieces 97 of the zipper 80 forward through the pair of second cutters 23, the cloth tape 81 and the chain belt 86 of the second middle split piece 97 are completely separated. The two separated cloth tapes 81 are defined as the cloth tape recovery part 94, and the separated closed chain belt 86 is defined as the chain belt recovery part 95.

[0142] Therefore, the zipper disassembly device and method involved in the present application can automatically disassemble the entire zipper 80, and disassemble it into the upper stop recovery part 91, the lower stop recovery part 93, the slider recovery part 92, the cloth tape recovery part 94 and the chain tape recovery part 95, effectively improving the zipper disassembly and recovery efficiency. In addition, when the end cutting unit 30 automatically cuts off the upper stop part and the lower stop part of the zipper 80, it can reduce the generation of debris, and also reduce the amount of debris contamination on the cloth tape 81 and the end cutting unit 30, which is conducive to the regeneration of the cloth tape 81 and reduces the occurrence rate of failure of the end cutting unit 30.

[0143] Furthermore, if Figures 2 to 5 As shown, the zipper splitting device also includes a fixed machine base 50, upper and lower stop recovery boxes 61 distributed on the front end side of the machine base 50, a slider recovery box 62 distributed on the left end side of the machine base 50, a cloth tape recovery box 63 distributed on the front side of the machine base 50, and a chain tape recovery box 64 distributed on the right end side of the machine base 50. The end separation mechanism 10 and the tape separation mechanism 20 are both installed on the machine base 50 and arranged side by side on the left and right. The machine base 50 is provided with upper and lower stop recovery channels 65, a slider recovery channel 66, a tape recovery channel 67 and a chain tape recovery channel 68. The upper ends of the upper and lower stop recovery channels 65 extend to the cutting support base plate 31, and the lower ends are connected to the upper and lower stop recovery boxes 61. The upper end of the slider recovery channel 66 extends to the front side of the slider card plate 40 toward the end cutting unit 30, and the lower end is connected to the slider recovery box 62. The upper end of the tape recovery channel 67 extends to the separation channel, and the lower end is connected to the tape recovery box 63. The upper end of the chain tape recovery channel 68 extends to the separation channel, and the lower end is connected to the chain tape recovery box 64.

[0144] In the process of automatically disassembling the entire zipper 80, the upper stop recovery part 91 and the lower stop recovery part 93 cut off by the end cutting unit 30 enter the upper and lower stop recovery box 61 through the upper and lower stop recovery channels 65, the slider recovery part 92 separated by the slider card 40 enters the slider recovery box 62 through the slider recovery channel 66, the cloth tape recovery part 94 separated by the tape separation mechanism 20 enters the cloth tape recovery box 63 through the cloth tape recovery channel 67, and the chain tape recovery part 95 separated by the tape separation mechanism 20 enters the chain tape recovery box 64 through the chain tape recovery channel 68. In this way, the present application realizes the classified recycling of each separated part after the entire zipper is disassembled, and realizes the automatic classified recycling of each separated part during the disassembly process, eliminating the subsequent classification operation, and greatly improving the efficiency of zipper disassembly and recycling.

[0145] Preferably, if Figure 2 and Figure 3As shown, the tape recovery box 63 is a closed tube structure, and an upper end cover that can be opened and closed is provided at its upper end. After the upper end cover is closed, the inner cavity of the tape recovery box 63 is a closed inner cavity. Based on this, the zipper disassembly device also includes an exhaust fan 71 and an exhaust duct 72, and the exhaust fan 71 is connected to the tape recovery channel 67 through the exhaust duct 72. After the entire zipper 80 is disassembled, among the upper stop recovery part 91, the lower stop recovery part 93, the slider recovery part 92, the tape recovery part 94 and the chain tape recovery part 95, only the tape recovery part 94 is a pure tape 81 structure, which does not contain metal parts and resin parts, so the tape part has a lighter weight. After the exhaust fan 71 and the exhaust duct 72 are configured, when the exhaust fan 71 is turned on, the exhaust fan 71 generates a suction force in the cloth tape recovery channel 67 through the exhaust duct 72. The suction force can accurately suck the cloth tape recovery part 94 separated by the belt separation mechanism 20 into the belt recovery channel and the cloth tape recovery box 63, thereby ensuring the reliability of the classified recovery of the cloth tape part.

[0146] Preferably, if Figures 2 to 5As shown, the upper and lower stop recovery boxes 61, the slider recovery box 62 and the chain belt recovery box 64 are all boxes with an open upper end structure, and the upper and lower stop recovery channels 65, the slider recovery channel 66 and the chain belt recovery channel 68 are all inclined channels extending obliquely downward. Among them, the upper and lower stop recovery channels 65 extend obliquely forward and downward, and their lower ends face the upper and lower stop recovery boxes 61; the slider recovery channel 66 extends obliquely to the lower left, and its lower end faces the slider recovery box 62; the chain belt recovery channel 68 extends obliquely to the lower right, and its lower end faces the chain belt recovery box 64. After the entire zipper 80 is disassembled, the upper stop recovery part 91, the lower stop recovery part 93, the slider recovery part 92, the tape recovery part 94 and the chain tape recovery part 95 are obtained. The upper stop recovery part 91, the lower stop recovery part 93, the slider recovery part 92 and the chain tape recovery part 95 all have metal parts or resin parts, and the metal parts or resin parts are the slider 83, the chain teeth 82, the upper stop 84 and the lower stop 85, so that the upper stop recovery part 91, the lower stop recovery part 93, the slider recovery part 92 and the chain tape recovery part 95 all have a certain weight. Therefore, the upper stop recovery part 91 and the lower stop recovery part 93 cut off by the end cutting unit 30 automatically fall into the upper and lower stop recovery channels 65 under the action of their own weight, and automatically slide downward along the upper and lower stop recovery channels 65, and then fall into the upper and lower stop recovery boxes 61; the slider recovery part 92 separated by the slider clamping plate 40 automatically falls into the slider recovery channel 66 under the action of its own weight, and automatically slides downward along the slider recovery channel 66, and then falls into the slider recovery box 62; the chain belt recovery part 95 separated by the belt separation mechanism 20 automatically falls into the chain belt recovery channel 68 under the action of its own weight, and automatically slides downward along the chain belt recovery channel 68, and then falls into the chain belt recovery box 64, finally realizing the reliable classification and recovery of the upper stop recovery part 91, the lower stop recovery part 93, the slider recovery part 92 and the chain belt recovery part 95 at a low cost.

[0147] Preferably, if Figure 2 and Figure 3 As shown, the frame includes a support frame body 51 composed of a plurality of support beams, a support top plate 52 fixed on the top of the support frame body 51, and a panel 53 fixed around the support frame body 51. The end separation mechanism 10 and the belt separation mechanism 20 are both fixed on the support top plate 52. The preferred structures of the end separation mechanism 10 and the belt separation mechanism 20 are described below.

[0148] End separation mechanism 10

[0149] like Figure 2 and Figure 6As shown, the end cutting unit 30 also includes a cutting support frame 33 and a cutting drive source 34. The bottom of the cutting support frame 33 is fixed to the support top plate 52 by several bolts, thereby the end cutting unit 30 is installed on the frame as a whole; the bottom of the slider card plate 40 is also fixed to the support top plate 52 by several bolts. In the end cutting unit 30, the cutting support bottom plate 31 can be fixed to the cutting support frame 33 or to the support top plate 52, and the cutting support bottom plate 31 is fixedly set; the first cutter 32 is installed on the cutting support frame 33 so as to be reciprocating up and down along the thickness direction of the zipper 80, and the first cutter 32 and the cutting support bottom plate 31 are arranged vertically opposite to each other along the thickness direction of the zipper 80. The cutting drive source 34 is installed on the cutting support frame 33 and is connected to the first cutter 32 in transmission, driving the first cutter 32 to reciprocate up and down, so as to realize the automatic cutting of the upper stopper part of the front end of the zipper 80 and the automatic cutting of the lower stopper part of the rear end of the zipper 80.

[0150] Furthermore, if Figure 6 As shown, the third cutter 35 is fixed on the cutting support base plate 31, and the first cutter 32 and the third cutter 35 are arranged vertically opposite to each other along the thickness direction of the zipper 80 and can be engaged; the third cutter 35 can be formed integrally on the cutting support base plate 31. In this way, the first cutter 32 constitutes an upper cutter distributed on the front side of the zipper 80, and the third cutter 35 constitutes a lower cutter distributed on the back side of the zipper 80; the upper cutter and the lower cutter cooperate to more efficiently and reliably cut the chain belt 86 of the zipper 80, that is, to more reliably cut the upper stopper part and the lower stopper part of the zipper 80. In addition, the upper end of the upper and lower stopper recovery channel 65 is distributed in front of the engagement point of the first cutter 32 and the third cutter 35; in this way, the cut upper and lower stopper parts automatically and accurately fall into the upper and lower stopper recovery channel 65.

[0151] Furthermore, if Figure 6As shown, the end cutting unit 30 also includes an anti-clip sleeve 36, a cylinder fixing plate 37, a cutter fixing plate 38, a cutter mounting plate 39, and a pair of linear guide rail assemblies 310 extending up and down. Among them, the anti-clip sleeve 36 is sleeved on the outer periphery of the cutting drive source 34; the cutting drive source 34 is fixed on the cylinder fixing plate 37, and the cylinder fixing plate 37 is fixed on the top surface of the cutting support frame 33, thereby installing the cutting drive source 34 on the cutting support frame 33. The cutting drive source 34 is a cylinder, and the lower end of the piston rod of the cylinder is connected to the cutter fixing plate 38 through a floating joint 311, driving the cutter fixing plate 38 to reciprocate up and down; the left and right ends of the cutter fixing plate 38 are respectively connected to the cutting support frame 33 through a set of linear guide rail assemblies 310, the cutter mounting plate 39 is fixed on the cutter fixing plate 38 by a number of screws, and the first cutter 32 is fixed on the cutter mounting plate 39 by a number of screws. Therefore, when the cylinder piston rod of the cutting drive source 34 is extended and retracted up and down, the cutter fixing plate 38 is driven to reciprocate up and down, and the cutter mounting plate 39 and the first cutter 32 move up and down synchronously with the cutter fixing plate 38, so that the first cutter 32 can move down for cutting and move up for resetting.

[0152] Preferably, if Figure 6 As shown, a rib plate 312 is fixed between the cylinder fixing plate 37 and the cutting support frame 33 to enhance the structural strength. Figure 6 and Figure 8 As shown, two pillars 313 extending up and down are fixed on the front end surface of the cutting support frame 33, and the two pillars 313 are symmetrically distributed left and right. The lower end of each pillar 313 is fixed on the supporting top plate 52 to enhance the structural strength.

[0153] Preferably, if Figure 6 As shown, a pair of joint baffles 314 are fixed on the top surface of the cutter fixing plate 38, and the pair of joint baffles 314 are against the left and right sides of the floating joint 311; in the process of the cylinder piston rod of the cutting driving source 34 driving the first cutter 32 to move up and down, the pair of joint baffles 314 can prevent the floating joint 311 from shaking left and right, and also prevent the first cutter 32 from shaking left and right, thereby improving the accuracy of cutting the upper stop part and the lower stop part of the zipper 80.

[0154] Furthermore, if Figure 6As shown, a feeding slot 315 extending left and right is provided on the rear side wall of the cutting support frame 33 facing the slider card plate 40, and the left end of the feeding slot 315 passes through the left side of the cutting support frame 33 and the rear side wall of the cutting support frame 33 from front to back. In the up-down direction, the width of the feeding slot 315 is configured to be greater than the thickness of the cloth tape 81 and the thickness of the chain belt 86, so that the feeding slot 315 allows the cloth tape 81 and the chain belt 86 of the zipper 80 to pass through. In the front-to-back direction, the feeding slot 315 and the slider stopper groove 41 face each other and are connected, and the area between the two is the slider accommodation area 316. In addition, the left end of the slider stop groove 41 passes through to the left side of the slider clamping plate 40; at the same time, the left end of the slider stop groove 41 is distributed on the right side of the left end of the feed groove 315, or in other words, in the left and right directions, both ends of the feed groove 315 are distributed on the outside of both ends of the slider stop groove 41. Therefore, when cutting the upper stop part and the lower stop part of the zipper 80, the way to put the zipper 80 into the end cutting unit 30 is: put the zipper 80 into it from the left end opening of the feed slot 315, and the position of the slider 83 on the zipper 80 should ensure that it is on the left side of the slider accommodating area 316; then, move the zipper 80 to the right, and the zipper 80 will then enter the slider stop groove 41 from the left end opening of the slider stop groove 41; finally, the zipper 80 is moved to the right to the position directly below the first cutter 32 and is supported on the third cutter 35; at this time, the cloth tape 81 and the chain tape 86 of the zipper 80 are both inserted into the feed slot 315 and the slider stop groove 41, and the slider 83 of the zipper 80 is located in the slider accommodating area 316. The upper end of the slider recovery channel 66 is located directly below the slider accommodation area 316 , so that the separated slider 83 can accurately fall into the slider recovery channel 66 .

[0155] Preferably, if Figures 7 and 8 As shown, the end cutting unit 30 further includes a first shield 317, which is fixed to the outer periphery of the cutting support frame 33 and shields the cylinder fixing plate 37 to the upper end of the feeding channel 315, playing a good protective role and preventing the accidental splashing of the broken materials during the cutting process. The first shield 317 can be made of transparent organic glass.

[0156] Furthermore, if Figures 6 to 8As shown, the end cutting unit 30 also includes a pair of feeding baffles 318 fixed on the left side wall of the cutting support frame 33, the pair of feeding baffles 318 are arranged in parallel up and down, and a zipper delivery port 3181 is formed between the two; the left end of the feeding channel 315 is a bell mouth portion 3151, and the zipper delivery port 3181 is distributed on the left end side of the bell mouth portion 3151, and the two are connected. At the same time, the outer peripheral side of the upper feeding baffle 318 is provided with an upper guide portion 3182 extending obliquely upward, and the outer peripheral side of the lower feeding baffle 318 is provided with a lower guide portion 3183 extending obliquely downward, and the upper guide portion 3182 and the lower guide portion 3183 are arranged vertically opposite to each other, and a guide port 3184 is formed between the two. By configuring the guide port 3184, the zipper delivery port 3181 and the bell mouth portion 3151, the zipper 80 can be easily moved to the right into the feeding channel 315.

[0157] Preferably, if Figure 6 As shown, the end separation mechanism 10 further includes a pair of slider baffles 319, which are distributed on the left and right sides of the slider accommodation area 316. Each slider baffle 319 includes a horizontal baffle portion 3191 extending horizontally, a baffle vertical portion 3192 extending vertically upward from one end of the baffle horizontal portion 3191, and a baffle inclined portion 3193 extending obliquely from the upper end of the baffle vertical portion 3192. The baffle horizontal portion 3191 is fixed on the supporting top plate 52, the baffle vertical portion 3192 is distributed on the inner side of the slider clamping plate 40 in the left-right direction, and the baffle inclined portion 3193 extends obliquely in a manner of moving upward and away from the slider accommodation area 316. The pair of slider baffles 319 reliably retain the separated slider 83 in the slider accommodation area 316, so that the separated slider 83 reliably falls into the slider recovery channel 66.

[0158] With separation mechanism 20

[0159] like Figure 2 , Fig.10 , Fig.11 and Fig.14 As shown, the belt separation mechanism 20 also includes a separation support frame 25 and an ultrasonic generator 24. The bottom of the separation support frame 25 is fixed to the support top plate 52 by a plurality of bolts, thereby the belt separation mechanism 20 is installed on the frame as a whole; the separation support bottom plate 21 is fixed to the separation support frame 25. The ultrasonic generator 24 is fixedly installed in the separation support frame 25, and the second cutter 23 is an ultrasonic cutter, and the ultrasonic generator 24 is connected to the ultrasonic cutter. The ultrasonic cutting method is used to cut the cloth belt 81, the cutting is accurate and reliable, and the quality of the cut surface of the cloth belt 81 can also be guaranteed.

[0160] Furthermore, the installation structure of the second cutter 23 is as follows: Fig.11 and Fig.13As shown, the belt separation mechanism 20 also includes a cutter fixing seat 213 fixed to the separation support frame 25, and a pair of cutter connecting arms 214 that are symmetrically distributed and both mounted on the cutter fixing seat 213, and a pair of second cutters 23 are rotatably mounted at the ends of each cutter connecting arm 214. Preferably, the belt separation mechanism 20 also includes a spacing adjustment mechanism, which acts on the pair of second cutters 23 to change the spacing between the pair of second cutters 23 in the width direction of the zipper 80, and is suitable for separating zippers 80 of different specifications and sizes. In this embodiment, the spacing adjustment mechanism includes an adjustment slot 2131 provided on the cutter fixing seat 213, and an adjustment bolt 215 inserted into the adjustment slot 2131, the adjustment slot 2131 extends left and right, and the adjustment bolt 215 is screwed into the cutter connecting arm 214 to connect the cutter connecting arm 214 with the cutter fixing seat 213. When the spacing between the pair of second cutters 23 needs to be adjusted, the adjusting bolt 215 is loosened to adjust the left and right positions of the pair of cutter connecting arms 214, that is, to adjust the spacing between the pair of second cutters 23; after the adjustment, the adjusting bolt 215 is tightened.

[0161] Preferably, if Fig.11 and Fig.12 As shown, the belt separation mechanism 20 is also provided with a scale ruler 216 and a pair of centering plates 217 on the upper side of the feed inlet 212 at the rear end of the separation channel, the center of the scale ruler 216 is the zero scale, and the pair of centering plates 217 are symmetrically distributed on the left and right sides of the zero scale. When the second middle split piece 97 of the zipper 80 is placed in the feed inlet 212, the chain belt 86 of the second middle split piece 97 is placed just below the area between the pair of centering plates 217, so that the second middle split piece 97 is conveniently aligned with the zero scale on the scale ruler 216, and it is also convenient to adjust the spacing of the pair of second cutters 23 according to the specifications of the zipper 80.

[0162] Furthermore, if Fig.11 and Fig.12 As shown, the belt separation mechanism 20 also includes a rotating shaft 26 extending left and right, and a transmission drive source 27 arranged on the right side wall of the separation support frame 25, the rotating shaft 26 is rotatably supported in the separation support frame 25; the transmission drive source 27 is a motor group, fixed on the support top plate 52; a driving gear 218 is fixed to the output end of the transmission drive source 27, and a driven gear 219 is fixed to the right end of the rotating shaft 26, and the driving gear 218 and the driven gear 219 are meshed; a pair of transmission rollers 22 are detachably mounted on the rotating shaft 26 by bolts. When the motor shaft of the transmission drive source 27 rotates, the driving gear 218 is driven to rotate, and the rotating shaft 26 is driven to rotate through the meshing of the driving gear 218 and the driven gear 219, and the pair of transmission rollers 22 rotate synchronously with the rotating shaft 26, thereby driving the cloth belt 81 pressed by the transmission roller 22 to move forward. In the present application, the transmission roller 22 adopts a detachable mounting structure relative to the rotating shaft 26, which is convenient for maintenance.

[0163] Preferably, if Fig.12 As shown, in the belt separation mechanism 20, there are two separation support bottom plates 21, which are distributed directly below each conveying roller 22. The belt separation mechanism 20 is provided with auxiliary rollers 220 on both the front and rear sides of each separation support bottom plate 21, and the auxiliary rollers 220 are rotatably mounted on the separation support frame 25. By arranging the auxiliary rollers 220, the cloth belt 81 conveyed forward can be more supported.

[0164] Furthermore, if Fig.11 , Fig.12 and Fig.14 As shown, the belt separation mechanism 20 also includes a clamping mechanism 28, a pair of clamping mounting plates 29, two pairs of clamping wheels 210, and two pairs of support wheels 211. The clamping mechanism 28 includes a clamping frame 281 and a clamping wrench assembly 282 installed on the clamping frame. The clamping frame 281 is fixed on the separation support frame 25 or fixed on the support top plate 52. The pair of clamping mounting plates 29 are distributed on the upper side of the rotating shaft 26, and the two clamping mounting plates 29 are symmetrically distributed left and right. The clamping mounting plates 29 can be installed in the clamping frame 281 so as to move up and down. The clamping wrench assembly 282 is connected to the pair of clamping mounting plates 29 in a transmission manner, and drives the pair of clamping mounting plates 29 to move up and down in the direction of approaching or moving away from the rotating shaft 26. A pair of clamping wheels 210 are installed at the lower end of each clamping mounting plate 29. The two clamping wheels 210 in each pair of clamping wheels 210 are symmetrically distributed front and back and are rotatably installed at the lower end of the clamping mounting plate 29. The two support wheels 211 in each pair of support wheels 211 are symmetrically distributed front and back and are rotatably mounted on the separation support frame 25. Each pair of clamping wheels 210 and each pair of support wheels 211 are arranged vertically opposite to each other and rotatably matched on the outer peripheral side of the rotating shaft 26, and a pair of transmission rollers 22 are distributed between the two pairs of clamping wheels 210 and the two pairs of support wheels 211. When the clamping wrench assembly 282 drives a pair of clamping mounting plates 29 to move downward, the clamping wheel 210 presses the rotating shaft 26 on the support wheel 211, and the rotating shaft 26 is rotatably supported in the separation support frame 25 by the two pairs of clamping wheels 210 and the two pairs of support wheels 211, and the transmission roller 22 is reliably pressed against the cloth belt 81, ensuring the reliability of the transmission roller 22 moving the cloth belt 81 forward.

[0165] Preferably, if Fig.10 and Fig.11 As shown, a part of the separation support frame 25 constitutes a second shield 221, and the rotating shaft 26, the conveying roller 22, the clamping wheel 210, the cutter fixing seat 213, the cutter connecting arm 214 and the second cutter 23 are all covered in the second shield 221, which plays a better protective role. The second shield 221 can be made of transparent organic glass.

[0166] Preferably, the junction of the chain belt recovery channel 68 and the separation channel is arranged on the rear side of the junction of the cloth tape recovery channel 67 and the separation channel; in this way, in the process of the second cutter 23 cutting the cloth tape 81, the cut part of the chain belt 86 can first fall into the chain belt recovery channel 68, while the cut part of the cloth tape 81 continues to move forward in the direction of the cloth tape recovery channel 67, thereby avoiding the chain belt recovery part 95 from being accidentally sucked into the cloth tape recovery channel 67.

[0167] In summary, the working process of the zipper disassembling device involved in the present application includes the following steps in sequence.

[0168] A1. Setting the initial state of the zipper 80: Fig.16a As shown, the slider 83 is located close to the upper stop 84 .

[0169] A2. Cut off the upper stop part of the zipper 80: insert the front end of the zipper 80 from the guide port 3184 on the left side of a pair of feeding baffles 318, and move the zipper 80 to the right into position. After the zipper 80 is moved into position: the slider 83 on the zipper 80 is located in the slider accommodating area 316; the distribution belt 81 and the chain belt 86 distributed on the front side of the slider 83 are inserted into the feed slot 315 of the cutting support frame 33, and are supported on the third cutter 35 and are located directly below the first cutter 32. The upper stop 84 is distributed on the front side of the first cutter 32 and the third cutter 35; the distribution belt 81 and the chain belt 86 distributed on the rear side of the slider 83 are inserted into the slider stop groove 41 of the slider clamp 40. The cutting drive source 34 drives the first cutter 32 to move downward, as shown in FIG. Fig.16a As shown, the first cutter 32 and the third cutter 35 engage with each other and cut off the portion of the front end of the zipper 80 having the upper stop 84 along the tangent line L1 to obtain the upper stop recovery portion 91. The upper stop recovery portion 91 falls into the upper and lower stop recovery box 61 through the upper and lower stop recovery channel 65. The cut-off drive source 34 drives the first cutter 32 to move upward and reset.

[0170] A3. Separating the slider 83 of the zipper 80: Pull the zipper 80 backward from the slider card 40. During this process, when the slider 83 contacts the front surface of the slider card 40, the slider card 40 limits the slider 83, restricting the slider 83 from moving backward from the slider stop groove 41, and relatively making the slider 83 detach forward from the chain belt 86; and the slider 83 detaches forward from the chain belt 86 while closing the chain belt 86. In this way, when the zipper 80 is completely pulled backward from the slider stop groove 41, the slider 83 is also detached from the chain belt 86, and the slider recovery part 92 is obtained. The slider recovery part 92 falls into the slider recovery box 62 through the slider recovery channel 66.

[0171] A4.
