Description

TECHNICAL FIELD

[0001] The present application relates to the field of zipper production, in particular to a zipper production equipment. BACKGROUND

[0002] In the prior art, as described in the patent document CN112704304A, "Zipper cutting, head threading, and stopper installing integrated machine and stopper installing device", the zipper production equipment has realized the automation of multiple functions, and can complete the cutting, head threading, and stopper installing of the zipper on a single equipment. The equipment adopts independent first and second conveying assemblies, which synchronously pull the zipper fabric through the parallel placement of the two conveying assemblies to separate at a suitable position for the installation of the puller. At the same time, the mechanism for installing the stopper in the equipment includes a rotating stopper die, which realizes the installation of the stopper through the taking of the stopper, the rotation of the stopper die, and the action of the stopper driving assembly below the stopper die.

[0003] However, this design also has many limitations and deficiencies. First, in the conveying system, although the independent double conveying assemblies can realize the synchronous conveying of the zipper fabric, they put forward higher requirements for precise synchronization control, which must be precisely controlled through a complex control system (such as PLC control). The synchronization control of the two independent conveying assemblies involves multiple precise calculations and real-time feedback adjustments, which not only increases the technical complexity and cost of the equipment, but also increases the possibility of faults to a certain extent. Since the two conveying assemblies need to be independently driven and controlled, the system may have different synchronization problems under long-time high-intensity work, which reduces the stability of the zipper fabric transmission and ultimately affects the quality of the product.

[0004] Secondly, the stopper installing mechanism in the existing equipment adopts a single cantilever design to support the rotation and positioning of the stopper die. This single cantilever structure is often insufficient in stability and rigidity under high-speed and long-time operation, and is prone to shaking and displacement deviation, which reduces the precision in the stopper installing process. At the same time, the single cantilever structure is prone to wear under the condition of long-time and frequent stress, which reduces the service life of the components and the overall stability of the equipment. In order to meet the requirements of high frequency and long time work, the single cantilever design is fragile, which is not conducive to ensuring the long-term stable operation of the equipment, and its maintenance and replacement cost is high.

[0005] In summary, in the prior art, the design of the zipper production equipment has significant deficiencies in synchronization control and structural stability, which directly affects the reliability of the equipment and the quality of the product. Developing a new type of zipper production equipment to realize a simpler synchronization control system and strengthen the structural stability of the stopper installing mechanism can significantly improve the production efficiency of the equipment and the final quality of the product. INNOVATION CONTENT

[0006] The purpose of this application is to overcome at least one deficiency of the prior art and provide a zipper production equipment that utilizes a single drive device to achieve efficient transmission without complex synchronous control, and adopts a double-frame stop mechanism, which will effectively reduce the failure rate of the equipment and extend its life.

[0007] To achieve the above objectives, this application discloses a zipper production equipment, which includes a machine base, a feed assembly and a stop assembly respectively mounted on the machine base and cooperating with each other. The feed assembly includes a linear slide, a floating feed mechanism mounted next to the linear slide, and a clamping mechanism cooperating with the feed mechanism. The floating feed mechanism avoids the clamping mechanism by lifting and lowering. The clamping mechanism includes a U-shaped single cantilever mounted on the linear slide and two telescopic clamps horizontally mounted opposite each other on the single cantilever. The single cantilever has an opening to avoid the working path of the zipper. During operation, the semi-finished zipper passes through the opening.

[0008] In some embodiments, the telescopic clamps can extend and retract horizontally, allowing the two telescopic clamps to pull apart the two fabric strips of the pull strap to complete the required upward stop action.

[0009] Furthermore, the feed head mechanism includes a vertically arranged guide rail and a fixture mounted on the guide rail with a feed head holder at the top. The fixture is driven by a cylinder to perform reciprocating linear motion in the vertical direction.

[0010] Furthermore, the zipper production equipment of this application also includes a zipper feeder mechanism for feeding zipper heads to the zipper feeder mechanism.

[0011] In some embodiments, the zipper production equipment of this application further includes a feeding assembly for feeding zipper tape to the threading assembly.

[0012] In some embodiments, the zipper production equipment of this application further includes an opening and closing guide mechanism located between the threading assembly and the top stop assembly.

[0013] A further problem to be overcome in this application is how to improve the working stability of the upper stop mechanism. To this end, the upper stop assembly includes a double support bearing and an upper stop mechanism mounted on the double support bearing. The upper stop mechanism is driven by a cylinder in conjunction with a rocker arm to realize up-and-down reciprocating motion.

[0014] Furthermore, the double-bracket bearing consists of two horizontally symmetrical L-shaped support plates and a bearing mounted on the L-shaped support plates.

[0015] Furthermore, the zipper production equipment of this application also includes a discharge mechanism that cooperates with the upper stop component. The discharge mechanism includes a first discharge clamp that can move horizontally. Opposite to the discharge mechanism, the double support bearing is provided with a clearance notch to avoid the first discharge clamp.

[0016] Further, the discharging mechanism further comprises a horizontally longitudinally moving second discharging chuck matched with the first discharging chuck, and a discharging conveying belt matched with the second discharging chuck, the first discharging chuck is handed over to the second discharging chuck after clamping the material from the upper stop assembly, and then the material is pulled to the discharging conveying belt by the second discharging chuck for discharging, through the cooperation of the first discharging chuck and the second discharging chuck, the upper clamping mechanism is avoided and the discharging is completed at the same time.

[0017] Compared with the prior art, the present application has at least one of the following beneficial effects:

[0018] 1. Simplify transmission synchronization control: by using a single drive device, the efficient transmission of the zipper fabric strip can be realized without a complex synchronization control system, reducing the technical complexity and failure rate of the control system.

[0019] 2. Enhance structural stability: the upper stop mechanism adopts a double support structure, which is more stable and rigid than a single cantilever structure, effectively reducing shaking and displacement deviation, ensuring the precision and durability of the upper stop operation.

[0020] 3. Prolong the service life of the equipment: through the double stand design and the simplified transmission structure, the wear and maintenance cost of the equipment is reduced, which helps to prolong the service life of the equipment and improve the continuity and efficiency of production.

[0021] The above listed beneficial effects are not exhaustive of all advantages. Other potential beneficial effects and detailed technical implementation methods will be further disclosed in the embodiments or other description parts of the present application. BRIEF DESCRIPTION OF DRAWINGS

[0036] Embodiments:

[0037] The application discloses a specific embodiment of a zipper production device. The zipper production device is cooperatively operated by multiple components to realize full-automatic production of a zipper.

[0038] Referring to the drawings Figures 1-3 , the machine table 1 is a basic support structure of the whole device, and various components are installed thereon, including a threading head component 2 for combining a puller with a zipper tape, an upper stop component 3 for stopping the zipper tape, a raw material component 4 for conveying the zipper tape, an open-close type guide mechanism 6 for clamping two cloth tapes in the zipper tape, and an ejection mechanism 5 for conveying the finished zipper tape.

[0039] In the above structure, referring to the drawings Figures 1-5 , the threading head component 2 is driven by the linear slide 201 to drive the single cantilever 203 and the puller feeding mechanism 202, so as to realize accurate threading head operation of the zipper tape.

[0040] In the above structure, referring to the drawings Figure 8 and 9 , the upper stop component 3 is combined with the double support bearing 301 and the upper stop mechanism 302 to complete the upper stop operation of the zipper.

[0041] In the above structure, the double support bearing 301 provides stable support, so that the upper stop mechanism 302 can keep high-precision operation in the processing process. The raw material component 4 and the open-close type guide mechanism 6 ensure stable feeding and accurate positioning of the zipper tape, thereby ensuring processing precision.

[0042] Finally, referring to the drawings Figures 1-3 , the ejection mechanism 5 cooperates with the first ejection clamp 501, the second ejection clamp 502 and the ejection conveying belt 503 to smoothly output the finished zipper. The close cooperation of various components makes the whole zipper production process efficient and coherent.

[0043] As a specific description of the above structure, referring to the drawings Figures 4-7 , the threading head component 2 includes the linear slide 201, the puller feeding mechanism 202 installed beside the linear slide, and the clamping and feeding mechanism 204 matched with the puller feeding mechanism 202. The clamping and feeding mechanism 204 is composed of the single cantilever 203 installed on the linear slide 201 and the two telescopic clamps 205 horizontally and oppositely installed on the single cantilever 203.

[0044] It should be understood that the linear slide 201 is used to realize controllable linear motion, and the single cantilever 203 is driven to complete predetermined path motion of the zipper tape. The single cantilever 203 has an opening 5 for avoiding the working path of the zipper, and the zipper semi-finished product (i.e., the zipper tape without the upper puller) passes through the opening 5. During work, the two telescopic clamps 205 can horizontally and oppositely stretch and retract, so as to be avoided from the puller feeding mechanism 202 while being matched with the upper stop mechanism 3 after pulling apart the two cloth tape portions of the zipper tape.

[0045] It can be understood that the two telescopic clamps 205 on the single cantilever 203 are driven by independent air cylinders 2003, and since the two telescopic clamps 205 are moved by the single cantilever 203, the design is simplified, and there is no complex synchronization control problem. Compared with the double conveying assembly in the prior art, the single cantilever 203 design can realize all motion control using a single linear slide 201, thereby reducing the technical complexity and failure rate. In addition, the single cantilever 203 structure only needs to use one linear slide 201, which also significantly reduces the overall manufacturing and maintenance costs.

[0046] In addition, as a component of the air land assembly 2, referring to the accompanying drawings Figure 3 The design of the puller feeding mechanism 202 is based on the principle of vertical guide rail and air cylinder driving. The jig 2001 is installed on the vertical guide rail, and the top of the jig 2001 is provided with a puller clamping position 2002. The jig 2001 is driven by the air cylinder to reciprocate in the vertical direction along the guide rail.

[0047] The specific steps are as follows: first, the jig 2001 is driven by the air cylinder to move downward along the guide rail, and the puller feeding mechanism 202 obtains the puller from the puller feeding mechanism, so that the puller enters the puller clamping position 2002 at the top of the jig 2001. Then, when the jig 2001 reaches the predetermined position, the threading is completed, the puller feeding mechanism 202 is sent by the clamping and feeding mechanism 204 to avoid the clamping and feeding mechanism 204 through height control, so as to ensure that there is no interference in the whole operation process, and then starts to work cooperatively with the clamping and feeding mechanism 204.

[0048] It should be understood that compared with the puller transmission method in the background art, the puller feeding mechanism of the embodiment can better adapt to the position change of the zipper semi-finished product through floating control, and ensure stable assembly.

[0049] In the embodiment, the zipper production equipment also includes a puller feeding mechanism (located in the machine table 1, not shown in the figure) which is specially used to provide pullers to the puller feeding mechanism 202.

[0050] In practical applications, the feeding path and feeding speed of the puller feeding mechanism can be adjusted according to the zipper production requirements to ensure the continuity of the whole production process. Those skilled in the art can understand that the design of the puller feeding path can refer to the existing public literatures in the background art to simplify the structure and improve the efficiency.

[0051] In order to ensure the effective work of the threading assembly, the equipment also includes a incoming assembly 4 for feeding the zipper tape to the threading assembly 2. The incoming assembly 4 can stably and continuously feed the threading assembly, avoiding production interruption caused by uneven feeding. At the same time, the structural design of the assembly ensures the stable feeding of the zipper tape, avoiding the winding problem, thereby improving the reliability of the overall production.

[0052] Referring to the drawings Figures 1-3 Between the head assembly 2 and the upper stop assembly 3, an open-close guiding mechanism 6 is also provided to firmly hold the zipper during production and ensure its positioning accuracy. The design of the open-close guiding mechanism 6 effectively prevents the zipper from shifting during the head insertion process and guides the zipper to quickly complete the head insertion action, thereby improving the processing accuracy and ensuring that the finished product quality meets the requirements.

[0053] It should be understood that for the working principle and structural design of the open-close guiding mechanism 6, those skilled in the art can refer to other published documents to understand the implementation of similar mechanisms in different application scenarios, thereby better understanding the present embodiment.

[0054] Referring to the drawings Figures 8-9 The design of the upper stop assembly 3 aims to improve production stability. It includes a double support bearing 301 and an upper stop mechanism 302. The upper stop mechanism 302 is driven by a gas cylinder and cooperates with a rocker arm to complete the up-down reciprocating motion, ensuring the stable transmission of the zipper between each processing step. The double support bearing 301 is composed of two horizontally symmetrical 7-shaped support plates 3001. This structural design helps to improve the stability of the support and reduce the precision loss caused by loose structure.

[0055] It should be understood that compared with the upper stop mechanism of the prior art, the present embodiment is more reasonable in the design of the support structure, which improves the rigidity and precision through the symmetrical double support structure, further enhancing the stability of the equipment during high-speed operation.

[0056] In order to cooperate with the upper stop assembly 3, the device also includes an ejection mechanism 5. The ejection mechanism is composed of a horizontally translatable first ejection chuck 501, a horizontally and vertically translatable second ejection chuck 502 cooperating with the first ejection chuck, and an ejection conveyor belt 503. During operation, the first ejection chuck 501 takes the processed zipper from the upper stop assembly 3 and hands it over to the second ejection chuck 502, and then the second ejection chuck sends the zipper to the ejection conveyor belt 503 to complete the ejection. Through the cooperation of the first ejection chuck 501 and the second ejection chuck 502, the ejection of the zipper can be smoothly completed while avoiding the upper stop mechanism 302, ensuring the smoothness of the entire ejection process and avoiding the ejection difficulty caused by insufficient space.

[0057] In summary, the zipper production equipment of the present embodiment realizes full automation from zipper feeding, head insertion, clamping, upper stop to ejection through the cooperation of each component.

[0058] The device of the present embodiment adopts various optimized structures, including the zipper head feeding mechanism 202, the double support bearing 301, and the multi-stage clamping ejection mechanism 5, which not only improves the processing accuracy and efficiency, but also effectively reduces the production defects caused by improper operation or unstable equipment.

[0059] Through the optimization of design and working principle, the device is suitable for various zipper production scenes, especially in industrial environments that require efficient and stable production, which can significantly improve the operation efficiency of the production line, reduce manual intervention, and reduce production costs. Those skilled in the art can understand that the contents not described in detail in the embodiment all belong to the prior art, and those skilled in the art can further improve and optimize on the basis of the embodiment by referring to the literature in the related background art.

[0060] It should be noted that in addition to the above structural description, the structures and contents not described in detail in the embodiment all belong to the category of prior art. Those skilled in the art can make appropriate improvements and optimizations to the structures in the embodiment by referring to existing published literature and related technical materials, and these improvements and optimizations should be considered as part of the embodiment.
