[0091] The following specific examples illustrate the implementation of this application. Those skilled in the art can easily understand other advantages and effects of this application from the content disclosed in this specification. This application can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this application. It should be noted that, unless otherwise specified, the following embodiments and features in the embodiments can be combined with each other.

[0092] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of this application. Therefore, the illustrations only show the components related to this application and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0093] Resin zippers are zippers made of synthetic resin materials and are widely used in clothing, bags, footwear, outdoor equipment, etc. Figure 1A The diagram shows the structure of a resin zipper. Figure 1A As shown, the resin zipper 1 includes a chain strap 11, a fabric strap 12, a slider 13, an upper stop 14, and a lower stop 15. For ease of description, the directions in this embodiment are defined as follows: the length direction of the resin zipper 1 is defined as the front-to-back direction, the width direction of the resin zipper 1 is defined as the left-to-right direction, and the thickness direction of the resin zipper 1 is defined as the up-to-down direction. When the slider 13 of the resin zipper 1 is pulled forward, the resin zipper 1 is closed; when the slider 13 of the resin zipper 1 is pulled backward, the resin zipper 1 is opened. Based on this, Figure 1A In the view shown, the left and right sides of the paper are the left and right directions, the top and bottom sides are the front and back directions, and the front and back sides are the top and bottom directions.

[0094] The zipper 11 comprises a series of interlocking teeth that interlock to open and close the resin zipper 1. The teeth can be made of injection-molded resin materials such as polyester resin, polyamide, or polyoxymethylene (POM), thus possessing good strength and wear resistance. The teeth can be trapezoidal, semi-circular, or prismatic in shape, and a well-designed shape ensures good meshing between them. The teeth interlock through side ramps and top grooves to guarantee stability under stress.

[0095] Fabric tape 12 serves as an auxiliary support component for the resin zipper 1, and is attached to clothing, bags, shoes, and other items using methods such as sewing. The material of fabric tape 12 may be synthetic fibers such as polyester or nylon, which possess good strength, abrasion resistance, and tear resistance. Fabric tape 12 can be dyed in various colors to meet different needs. In some implementations, waterproof, fireproof, or antistatic coatings may be added to fabric tape 12 as required.

[0096] The zipper pull 13 is the part that the user operates directly. The opening and closing of the resin zipper 1 can be achieved by sliding the zipper pull 13.

[0097] Figure 1B The diagram shown is a structural schematic of the slider 13 in an embodiment of this application. Figure 1B As shown, the zipper pull 13 includes a zipper pull body 131, a pull tab 132, and a connecting post 133. The zipper pull body 131 can be made of metal materials such as zinc alloy or stainless steel. The pull tab 132 is used to drive the zipper pull 13 to slide along the chain belt 11, thereby realizing the opening and closing of the chain belt 11. In some implementations, the material of the pull tab 132 includes metal materials such as zinc alloy or stainless steel, and the alloy raw materials can be obtained by recycling the pull tab 132. In other implementations, the material of the pull tab 132 can include resin, and the waste resin can be obtained by recycling the pull tab 132, thereby obtaining resin raw materials.

[0098] Along the length of the chain belt 11, the upper stop 14 is provided at the front end of the chain belt 11 and fixed to the cloth belt 12 to limit the front limit position of the zipper head 13 and prevent the zipper head 13 from detaching forward from the chain belt 11.

[0099] The lower stop 15 is located at the rear end of the chain belt 11 and fixed to the cloth belt 12. It is used to limit the rear limit position of the zipper head 13 and prevent the zipper head 13 from detaching from the chain belt 11.

[0100] The production process of resin zipper 1 involves multiple steps. Figure 2 The main processes involved in the production of resin zipper 1 are shown, including injection molding, shaping and cooling, fabric splicing, dyeing and post-treatment, cutting and assembly, etc. These processes often generate processing waste. For example, in the injection molding process, debugging and trial molding are required at the start of production or when changing molds, which generates waste resin. Furthermore, finished resin zippers may not be delivered due to customer changes or order cancellations, or quality issues, and these zippers will also be discarded. Failure to recycle these processing wastes and discarded resin zippers (hereinafter referred to as discarded zippers) will lead to serious resource waste and environmental pollution.

[0101] To address at least the aforementioned problems, embodiments of this application provide a recycling method. The recycling method provided by embodiments of this application will be described below with reference to the accompanying drawings.

[0102] Figure 3 The diagram shows the process flow of a recycling method provided in an embodiment of this application. Figure 3 As shown, the recycling method includes a first collection step S31, a second collection step S32, a recycling step S33, and a reprocessing step S34.

[0103] In the first collection step S31, waste zippers are collected and separated into waste chain tape, waste fabric tape and waste zipper head, and waste resin is obtained using waste chain tape and / or waste zipper head.

[0104] In the second collection step S32, processing waste generated during the zipper processing stage is collected, including waste resin, waste fabric tape, and waste zipper heads.

[0105] For example, waste resin can originate from the injection molding process (or injection stage). During injection molding, molten resin flows into the resin runner and gate, and this resin cools to form waste resin. Residual material in the injection molding machine barrel needs to be cleaned during material changeovers to prevent mixing of different materials from affecting product quality. This residual material is discharged during the cleaning process, becoming waste resin.

[0106] For example, waste fabric tape can originate from the sewing process. During the sewing of chain straps and fabric tape, improper operation or equipment problems may produce defective products, resulting in substandard waste fabric tape. Waste fabric tape can also be generated by trimming excess scraps of fabric.

[0107] For example, discarded zipper heads can originate from the assembly process. During the assembly of zipper heads, operational errors or improper equipment adjustments may cause the zipper heads to malfunction, resulting in defective discarded zipper heads.

[0108] For example, discarded zipper pulls may be caused by poor surface treatment such as painting or electroplating, scratches, or improper installation and clamping.

[0109] It should be noted that the above only exemplifies several possible sources of waste resin, waste fabric tape, and waste zipper heads, but this application is not limited thereto. All waste resin, waste fabric tape, and waste zipper heads that meet quality requirements and are generated at the resin zipper production site can be collected in the second collection process S32.

[0110] The recycling process S33 includes waste resin recycling sub-process S331, waste fabric tape recycling sub-process S332, and waste zipper head recycling sub-process S333.

[0111] In the waste resin recycling sub-process S331, the waste resin from the first collection process S31 and / or the second collection process S32 is crushed into resin particles, and the resin particles are melted and reprocessed into resin raw materials.

[0112] In the waste fabric recycling sub-process S332, the waste fabric from the first collection process S31 and / or the second collection process S32 is reprocessed into fiber raw materials.

[0113] In the waste zipper head recycling sub-process S333, the waste zipper heads from the first collection process S31 and / or the second collection process S32 are decomposed to obtain recycled alloy, and the recycled alloy is melted and remade into alloy raw materials.

[0114] In the reprocessing step S34, resin raw materials, fiber raw materials, and alloy raw materials are reprocessed to produce new resin zippers.

[0115] As described above, in this embodiment, waste zippers and processing waste generated at the production site are collected through a first collection step S31 and a second collection step S32, and the waste zippers are disassembled. A recycling step S33 recovers waste resin, waste fabric tape, and waste zipper heads to obtain resin raw materials, fiber raw materials, and metal raw materials. These raw materials are used in a reprocessing step S34 to produce new resin zippers. This method reduces resource consumption and waste emissions, and helps lower production costs and protect the environment. Furthermore, in this embodiment, only processing waste and waste zippers generated at the processing site are recycled, and the recovered raw materials are reused in the production of new resin zippers. This closed-loop approach ensures that the quality of the recycled raw materials meets requirements, thereby improving the quality of the resin zippers.

[0116] In some implementations, the waste resin from the first collection step S31 and / or the second collection step S32 is colored resin. This resin is crushed into resin particles and melted to obtain a mixed-color recycled resin. Black pigment can be added to the mixed-color recycled resin to cover the original color, thereby obtaining black recycled resin. This black recycled resin can be reused as a resin raw material.

[0117] In some implementations, the recycling method may further include: in the waste resin recycling sub-step S331, sorting the waste resin from the first collection step S31 and / or the second collection step S32 to remove waste resin containing impurities and prevent contamination. For example, mechanical screening, magnetic separation, gravity separation, etc., can be used to sort out waste resin that does not contain impurities. By sorting the waste resin, waste resin mixed with impurities such as metal particles and fluorescent agents can be removed, thereby ensuring that the quality of the recycled resin raw materials meets the requirements.

[0118] For example, in the waste resin recycling sub-process S331, specific types of waste resin can be sorted as needed. For instance, only POM (Polyoxymethylene) resin can be sorted.

[0119] In some implementations, the waste resin recycling sub-process S321 may include: crushing the waste resin to form fine resin particles; heating these resin particles to a specific temperature through a melting process to completely melt them into a uniform liquid resin; and reprocessing the liquid resin into high-quality resin raw materials through an extrusion granulation process.

[0120] In some implementations, reprocessing waste fabric strips from the first collection step S31 and / or the second collection step S32 into fiber raw materials includes: sorting waste fabric strips from the first collection step S31 and / or the second collection step S32 to obtain dyed waste fabric strips and undyed first waste fabric strips; decolorizing the dyed waste fabric strips to obtain undyed second waste fabric strips; and reprocessing the first and second waste fabric strips into fiber raw materials.

[0121] Please see Figure 4 In some implementations, the waste fabric tape recycling sub-process S332 further includes:

[0122] S3321, the waste fabric strip from the first collection step S31 and / or the second collection step S32 is broken down into fiber scraps.

[0123] For example, breaking down waste fabric tape into fiber fragments may include: pre-treating the waste fabric tape to remove impurities; dividing the pre-treated waste fabric tape into small-sized fabric tape fragments, the dividing process of which may be achieved by a cutting machine or a shearing machine; and processing the fabric tape fragments into fiber fragments, ensuring that the particle size of the fiber fragments meets a predetermined standard.

[0124] S3322, chemically treats fiber scraps and reprocesses them into fiber raw materials.

[0125] For example, chemically treating fiber scraps and reprocessing them into fiber raw materials includes: dissolving and reconstituted the fiber scraps to obtain fiber raw materials.

[0126] As described above, in this embodiment, waste fabric tape is broken down into fiber scraps, which are then chemically treated and reprocessed into fiber raw materials. This method enables the regeneration of waste fabric tapes, effectively removes impurities, and improves the quality of the fiber raw materials.

[0127] In some implementations, the recycling method may further include: in the waste zipper head recycling sub-process S333, sorting the waste zipper heads from the first collection process S31 and / or the second collection process S32 to obtain coated waste zipper heads and uncoated waste zipper heads, and performing decoating and / or deplating treatment on the coated waste zipper heads.

[0128] For example, a chemical decoating method can be used to remove the coating from discarded, coated zipper pulls. Specifically, an appropriate chemical solvent can be selected based on the type of coating material, such as paint, varnish, or powder coating. The discarded, coated zipper pulls are immersed in a container for decoating. After immersion, the discarded zipper pulls are rinsed and neutralized to obtain decoated zipper pulls.

[0129] In some implementations, in the first collection step S31, a zipper splitting mechanism is used to split the discarded zipper into a discarded zipper tape, a discarded fabric tape, and a discarded zipper pull. The zipper splitting mechanism includes an end separation section and a tape separation section. The end separation section is used to separate the discarded zipper pull from the discarded zipper. The tape separation section is used to separate the discarded zipper tape and the discarded fabric tape from the discarded zipper.

[0130] In some implementations, the recycling method may further include: in the waste fabric tape recycling sub-process S332, using an end separation section to cut off the accessories of the waste fabric tape. These accessories include an upper stop, a lower stop, and / or an opening / closing device, etc.

[0131] For example, such as Figure 5AAs shown, the end separation section 51 includes an end cutting unit 511 and a zipper pull plate 512. The end cutting unit 511 includes a cutting support base plate 5111 and a first cutter 5112 movable towards or away from the cutting support base plate 5111. Through the reciprocating motion of the first cutter 5112, the upper stop portion and the lower stop portion of the discarded zipper are cut off. After cutting, the discarded zipper is pulled out of the end cutting unit 511 along its length. The zipper pull plate 512 is distributed on the rear side of the end cutting unit 511 along the direction in which the discarded zipper is pulled out of the end cutting unit 511. The zipper pull plate 512 is provided with a zipper pull stop groove 5121 that runs through the front and back. In the vertical direction, the width of the zipper pull stop groove 5121 is configured to be less than the minimum thickness of the zipper pull but greater than the thickness of the fabric and the chain, so that the zipper pull stop groove 5121 only allows the fabric and chain of the discarded zipper to pass through, but does not allow the zipper pull to pass through. Thus, after the end-cutting unit 511 completes the cutting operation, during the process of pulling the discarded zipper backward from the end-separation section 51, the zipper head clamp 512 stops the zipper head between the end-cutting unit 511 and the zipper head clamp 512; as the discarded zipper is completely pulled out, the zipper head naturally separates from the zipper belt, thereby obtaining the discarded zipper head, as shown. Figure 5B As shown.

[0132] For example, such as Figure 5C and 5D As shown, the separation section 52 includes a separation support base plate 521, a pair of rotatable conveyor rollers 522 for pressing the fabric 1, and a pair of second cutters 523 for cutting the fabric strip. The pair of conveyor rollers 522 and the separation support base plate 521 are arranged side by side vertically along the thickness direction of the waste zipper, and a separation channel is formed between them. The separation channel allows the fabric strip and chain of the waste zipper to pass through. The separation channel is a through channel that extends front to back, and the rear end of the separation channel constitutes an inlet 5211. The two conveyor rollers 522 are arranged side by side horizontally along the width direction of the waste zipper, and the two second cutters 523 are arranged side by side horizontally along the width direction of the waste zipper; moreover, the pair of second cutters 523 are distributed inside the pair of conveyor rollers 522 along the width direction of the waste zipper. When the conveyor roller 522 rotates, it drives the fabric belt to move forward. During this process, the second cutter 523 cuts the fabric belt below it. After all the waste zippers that have entered the separation mechanism have passed forward through the conveyor roller 522 and the second cutter 523, the fabric belt part and the chain belt part of the waste zippers are automatically separated, thus obtaining waste fabric belt and waste chain belt.

[0133] For example, the process of separating the waste zipper head from the waste zipper using the end separation part 51, and separating the waste zipper belt and waste fabric belt from the waste zipper using the belt separation part 52 is as follows:

[0134] Step 1: Place one end of the entire discarded zipper into the end separation section 51, positioning the front portion of the discarded zipper with the upper stop member on the cutting support base plate 5111. Position the discarded zipper head between the end cutting unit 511 and the zipper head retainer plate 512, while simultaneously threading the fabric and chain of the discarded zipper into the zipper head stop groove 5121 of the zipper head retainer plate 5122. The first cutting blade 5112 moves towards the cutting support base plate 5111. The first cutting blade 5112 cuts off the portion of the discarded zipper with the upper stop member along the tangent line L1. The cut upper stop member portion is defined as the upper stop member recycling portion M1, as shown below. Figure 5B As shown. The first cutting blade 5112 moves away from the cutting support base plate 5111 and resets.

[0135] Step 2: Pull the discarded zipper backward from the end cutting unit 511 and the zipper head stop groove 5121. The zipper head stop groove 5121 stops the zipper head on the chain. After the discarded zipper is completely pulled backward from the zipper head stop groove 5121, the zipper head will automatically detach from the chain. The detached zipper head is the discarded zipper head M2. The remaining part of the discarded zipper after cutting off the upper stop and separating the zipper head is defined as the first intermediate splitting part M3. Since the discarded zipper head M2 moves forward relative to the chain during the process of detaching from the chain, the chain is in a closed state in the first intermediate splitting part M3 after the discarded zipper head M2 detaches, and the rear end of the chain is the lower stop fixed to the fabric belt.

[0136] Step 3: After placing the first intermediate splitting piece M3 into the end splitting part 51, position the rear end portion of the discarded zipper with the lower stop piece on the cutting support base plate 5111, and also ensure that both the fabric tape and the chain tape of the discarded zipper are threaded into the zipper head stop groove 5121 of the zipper head clamping plate 512. The first cutting blade 5112 moves towards the cutting support base plate 5111, as... Figure 5E As shown. The first cutter 5112 cuts off the portion of the discarded zipper with the bottom stop along the tangent line L2. The cut-off bottom stop portion is defined as the bottom stop recycling portion M4, and the remaining portion of the first intermediate splitting piece M3 after the bottom stop portion is cut off is defined as the second intermediate splitting piece M5. Then, the second intermediate splitting piece M5 of the discarded zipper is pulled back from the end cutting unit 511 and the zipper head stop groove 5121; the first cutter 5112 moves away from the cutting support base plate 5111 and resets. The second intermediate splitting piece M5 only includes the fabric tape and chain tape of the discarded zipper, and the chain tape is in a closed state.

[0137] Step 4: The second intermediate split piece M5 of the waste zipper, processed in Step 3, is fed forward into the separation channel through the inlet 5211 with the separation section 52; a pair of conveyor rollers 522 rotate, driving the second intermediate split piece M5 of the waste zipper forward. During this process, if... Figure 5FAs shown, the left second cutter of the pair of second cutters 523 cuts the left side of the fabric strip along tangent line L3, and the right second cutter of the pair of second cutters 523 cuts the right side of the fabric strip along another tangent line L4. When the pair of conveyor rollers 522 drive the second intermediate split piece M5 of the waste zipper to pass forward completely through the pair of second cutters 523, the fabric strip and chain belt of the second intermediate split piece M5 are completely separated, resulting in waste fabric strip M6 and waste chain belt M7.

[0138] As described above, the zipper splitting mechanism provided in this application embodiment can automatically split the entire waste zipper to obtain waste zipper heads, waste fabric tape, and waste zipper tape, effectively improving the efficiency of waste zipper splitting and recycling.

[0139] Please see Figure 6A and Figure 6B In some implementations, the process of disassembling discarded zipper heads to obtain recycled alloys includes the following steps S61 to S64.

[0140] S61, adjust the posture of the discarded zipper head so that the zipper pull tab 132 is perpendicular to the zipper head body 131. For example, an image of the discarded zipper head can be acquired by an image acquisition device, the relative posture of the zipper pull tab 132 and the discarded zipper head can be obtained by an image recognition algorithm, and the posture of the discarded zipper head can be adjusted by a robotic arm, gripper, etc., so that the zipper pull tab 132 is perpendicular to the zipper head body 131.

[0141] S62, the pull tab 132 is cut off from the discarded pull head using a pull tab cutter to obtain the pull tab 132. Exemplarily, a fixing device can be used to fix the pull head body 131 and the pull tab 132 to maintain their relative positions. The pull tab cutter can be a cutter from a CNC cutting machine, laser cutting machine, etc.

[0142] S63, the connecting post 133 is cut from the slider body 131 using a post cutter to obtain the slider body 132. For example, the slider body 132 can be fixed using a fixing device. The post cutter can be a cutter from a CNC cutting machine, laser cutting machine, or the like.

[0143] S64, the pull tab 132 and the pull head body 131 are disassembled and the recycled alloy is obtained.

[0144] The discarded zipper pull mainly includes components such as the pull tab 132, the connecting post 133, and the zipper pull body 131, and these components are not made of the same material. Based on this, in the embodiments of this application, the discarded zipper pull can be cut into the zipper pull body 131 and the pull tab 132 by using a pull tab cutter and a post cutter, and then the zipper pull body 131 and the pull tab 132 can be decomposed to obtain recycled alloy.

[0145] The scope of protection of the recycling method provided in this application is not limited to the order of steps listed in this application. Any solution implemented by adding, subtracting, or replacing steps in the prior art based on the principles of this application is included within the scope of protection of this application.

[0146] This application also provides a recycling system that can implement the recycling method provided in this application. However, the implementation device of the recycling method provided in this application includes, but is not limited to, the structure of the recycling system listed in this application. Any structural modifications and substitutions of the prior art made in accordance with the principles of this application are included within the protection scope of this application.

[0147] Figure 7 The diagram shown is a structural schematic of a recycling system provided in an embodiment of this application. Figure 7 As shown, the recycling system 7 includes a first collection device 71, a second collection device 72, a recycling device 73, and a reprocessing device 74.

[0148] The first collection device 71 is used to collect waste zippers and separate them into waste zipper tape, waste fabric tape and waste zipper head, and to obtain waste resin using the waste zipper tape and / or waste zipper head.

[0149] The second collection device 72 is used to collect processing waste generated during the zipper processing stage, including waste resin, waste fabric tape, and waste zipper heads.

[0150] The recycling device 73 includes a waste resin recycling mechanism 731, a waste fabric tape recycling mechanism 732, and a waste zipper pull recycling mechanism 733.

[0151] Waste resin recycling unit 731 is used to crush waste resin from the first collection device 71 and / or the second collection device 72 into resin particles, and melt the resin particles to reprocess them into resin raw materials.

[0152] Waste fabric recycling mechanism 732 is used to reprocess waste fabric from the first collection device 71 and / or the second collection device 72 into fiber raw materials.

[0153] The waste zipper head recycling mechanism 733 is used to decompose the waste zipper heads from the first collection device 71 and / or the second collection device 72 to obtain recycled alloy, and then melt the recycled alloy to remanufacture it into alloy raw materials.

[0154] The reprocessing device 74 is used to reprocess resin raw materials, fiber raw materials and alloy raw materials to produce zippers.

[0155] In some implementations, the waste resin recycling mechanism 731 includes a first sorting unit. The first sorting unit is used to sort waste resin from the first collection device 71 and / or the second collection device 72 to remove waste resin containing impurities and prevent contamination. For example, the first sorting unit can use mechanical screening, magnetic separation, gravity separation, or other methods to sort out waste resin free of impurities. By sorting the waste resin, waste resin containing impurities such as metal particles and fluorescent agents can be removed, thereby ensuring that the quality of the recycled resin raw materials meets requirements. Exemplarily, the first sorting unit can sort specific types of waste resin as needed. For example, it can sort only POM resin.

[0156] In some implementations, the waste resin recycling facility 731 can crush waste resin into fine resin particles, heat these resin particles to a specific temperature through a melting process to completely melt them into a uniform liquid resin, and then reprocess the liquid resin into high-quality resin raw materials through an extrusion granulation process.

[0157] In some implementations, the waste fabric tape recycling mechanism 732 includes a second sorting unit. The second sorting unit is used to: sort waste fabric tape from the first collection process and / or the second collection process to obtain dyed waste fabric tape and undyed first waste fabric tape; decolorize the dyed waste fabric tape to obtain undyed second waste fabric tape; and reprocess the first and second waste fabric tapes into fiber raw materials.

[0158] Please see Figure 8 In some implementations, the waste fabric recycling mechanism 732 may include a waste fabric dismantling unit 7321 and a fiber raw material manufacturing unit 7322. The waste fabric dismantling unit 7321 is used to dismantle the waste fabric from the first collection device 71 and / or the second collection device 72 into fiber scraps. The fiber raw material manufacturing unit 7322 is used to chemically treat the fiber scraps and reprocess them into fiber raw materials.

[0159] For example, the waste fabric strip decomposition unit 7321 may decompose the waste fabric strip into fiber fragments by: pre-treating the waste fabric strip to remove impurities; dividing the pre-treated waste fabric strip into small-sized fabric strip fragments, the dividing process of which may be achieved by a cutting machine or a shearing machine; and processing the fabric strip fragments into fiber fragments to ensure that the particle size of the fiber fragments meets a predetermined standard.

[0160] For example, the fiber raw material production unit 7322 chemically processes fiber scraps and reprocesses them into fiber raw materials by dissolving and reconstituted fiber scraps to obtain fiber raw materials.

[0161] Please see Figure 9In some implementations, the waste zipper pull recycling mechanism 733 may include a third sorting unit 7331 and a coating / electroplating removal unit 7332. The third sorting unit 7331 is used to sort waste zipper pulls from the first collection device 71 and / or the second collection device 72 to obtain coated waste zipper pulls and uncoated waste zipper pulls. The coating / electroplating removal unit 7332 is used to remove the coating and / or remove the electroplating from the coated waste zipper pulls.

[0162] For example, the coating / electroplating removal unit 7332 can use a chemical decoating method to remove the coating from the discarded zipper heads. Specifically, the coating / electroplating removal unit 7332 can select an appropriate chemical solvent according to the type of coating material, such as paint, baking paint, powder coating, etc., immerse the discarded zipper heads in a container for decoating treatment, and then rinse and neutralize the immersed discarded zipper heads to obtain decoated discarded zipper heads.

[0163] In some implementations, the first collection device 71 includes a zipper splitting mechanism for separating the discarded zipper into a discarded zipper tape, a discarded fabric tape, and a discarded zipper pull. The zipper splitting mechanism includes an end separation section and a tape separation section. The end separation section is used to separate the discarded zipper pull from the discarded zipper, and the tape separation section is used to separate the discarded zipper tape and the discarded fabric tape from the discarded zipper. Furthermore, the end separation section can also be used to cut off accessories from the discarded fabric tape. The structures of the end separation section and the tape separation section are as follows... Figure 5A , 5C As shown in 5D, it will not be elaborated upon here.

[0164] In some implementations, the first collection device 71 includes a slider splitting mechanism and a material dismantling mechanism. The slider splitting mechanism includes a posture adjustment section, a slider cutter, and a column cutter. The posture adjustment section adjusts the posture of the discarded slider so that the slider's slider tab is perpendicular to the slider body. The slider cutter cuts the slider tab from the discarded slider to obtain the slider tab. The column cutter cuts the connecting column from the slider body to obtain the slider body. The material dismantling mechanism dismantles the slider tab and the slider body to obtain a recycled alloy.

[0165] For example, the posture adjustment unit can acquire an image of the discarded zipper head through an image acquisition device, obtain the relative posture of the zipper tab and the discarded zipper head using an image recognition algorithm, and adjust the posture of the discarded zipper head through a robotic arm, gripper, etc., so that the zipper tab of the zipper head is perpendicular to the zipper head body.

[0166] For example, the sheet cutter and / or column cutter can be a cutter in a CNC cutting machine, laser cutting machine, etc.

[0167] In some implementations, the second collection device 72 includes a waste resin collection mechanism for collecting waste resin in the resin channel of the injection process and / or waste resin discharged by the injection equipment during material change.

[0168] In the embodiments provided in this application, it should be understood that the disclosed systems, apparatuses, or methods can be implemented in other ways.

For instance, the division of modules / units is only a logical functional division, and in actual implementation, there may be other division methods. For example, multiple modules or units may be combined or integrated into another system, or some features may be ignored or not executed. Furthermore, the coupling or direct coupling or communication connection shown or discussed may be through some interfaces; the indirect coupling or communication connection of apparatuses or modules or units may be electrical, mechanical, or other forms.

[0169] The modules / units described as separate components may or may not be physically separate.

To clearly illustrate the interchangeability of hardware and software, the components and steps of the various examples have been generally described in terms of functionality in the foregoing description. Whether these functions are implemented in hardware or software depends on the specific application and design constraints of the technical solution.

[0172] In summary, the embodiments of this application provide a recycling method and system. These embodiments can recycle processing waste and / or discarded zippers generated at the resin zipper production site and reuse the recycled raw materials in zipper production. This method can reduce resource consumption and waste emissions, and is beneficial for reducing production costs and protecting the environment.

[0173] Furthermore, embodiments of this application can focus solely on recycling waste resin generated at the production site. Since the waste resin generated at the production site is of essentially the same quality, embodiments of this application can avoid a decline in the quality of the recycled resin raw materials due to differences in the quality of the recycled waste resin. Similarly, embodiments of this application can avoid a decline in the quality of the recycled fiber raw materials due to differences in the quality of the recycled waste fabric strips, and can also avoid a decline in the quality of the recycled alloy raw materials due to differences in the quality of the recycled waste zipper pulls.

[0174] Furthermore, the embodiments of this application can remove waste resin mixed with impurities such as metal particles and fluorescent agents through a sorting sub-process, thereby ensuring that the quality of the recycled resin raw materials meets the requirements. In addition, the embodiments of this application can only recycle waste resin generated on the production site, thus reducing the difficulty of sorting.

[0175] Therefore, this application effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0176] The above embodiments are merely illustrative of the principles and effects of this application and are not intended to limit this application. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this application. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this application should still be covered by the claims of this application.
