Abstract
Description
Technical Field
[0001] This invention relates to the field of zipper manufacturing equipment technology, specifically to a zipper stop-code forming and zipper assembly equipment and method. Background Technology
[0002] After the zipper pull is threaded onto the zipper tape, the upper and lower stop blocks need to be injection molded at the beginning and end of the zipper tape, respectively. After the stop blocks are formed, the zipper teeth on the tape are closed. Most existing zipper production equipment uses two sets of injection molding machines or one machine with two processes to injection mold the upper and lower stop blocks at both ends of the zipper tape. This makes the equipment mechanism and processes cumbersome and complex, increasing equipment costs and hindering equipment maintenance. Furthermore, existing zipper production equipment suffers from unstable clamping effects on the zipper pin and zipper block during insertion, lacks limiting measures for the lower stop block, and exhibits unstable engagement of the zipper teeth without limiting measures for the teeth and zipper tape. This process easily leads to misalignment of the zipper pin, zipper block, teeth, and zipper tape, resulting in insertion and engagement failures. Therefore, there is an urgent need for a device that can simultaneously perform injection molding of the upper and lower stop blocks, and that can ensure the stability of the process of inserting the zipper pin into the zipper block and the engagement of the zipper teeth. Summary of the Invention
[0003] This invention addresses the problems in existing zipper equipment, such as the use of two sets of injection molding equipment or one set of equipment with two processes to injection mold the upper and lower stop codes at the beginning and end of the zipper tape, poor stability during the insertion of the zipper pin into the zipper block, and the lack of effective limiting measures to ensure the stability of the zipper closing process. The invention provides a zipper stop code molding and zipper closing equipment and method to solve these problems.
[0004] The technical solution adopted by the present invention to solve the above problems is as follows: a zipper stop-code molding and zipper assembly equipment, comprising: a machine body, an injection molding mechanism, a zipper assembly mechanism, and a conveying mechanism. The injection molding mechanism is installed on one side of the top of the machine body, the zipper assembly mechanism is installed on the other side of the top of the machine body, and the conveying mechanism is installed on the machine body. The injection molding mechanism includes an upper mold assembly and a lower mold assembly connected to each other. An upper module and a lower module are respectively provided at the bottom of the upper mold assembly and the top of the lower mold assembly. The upper module cooperates with the lower module to perform injection molding of the lower stop-code at the tail end of the previous zipper tape and simultaneously perform injection molding of the upper stop-code at the beginning end of the next zipper tape. The injection molding of the stop code includes a zipper pin and a zipper block. The zipper closing mechanism includes a left worktable, a right worktable, and a pressing device. The left and right worktables are respectively installed on both sides of the zipper tape. The left and right worktables cooperate to insert the zipper pin into the zipper block. The pressing device is used to close the zipper teeth on the side of the stop code in the zipper tape. The conveying mechanism includes a first driving device and a second driving device. Both the first and second driving devices can drive the zipper tape to be conveyed. The zipper tape passes through the injection molding mechanism, the first driving device, the zipper closing mechanism, and the second driving device in sequence. The side of the injection molding mechanism away from the first driving device is designated as the injection inlet side, and the side facing the first driving device is designated as the injection outlet side. Similarly, the side of the zipper closing mechanism away from the second driving device is designated as the zipper inlet side, and the side facing the second driving device is designated as the zipper outlet side.
[0005] Preferably, the upper mold assembly includes an upper mold support, an injection molding device, and a mold closing device. The injection molding device and the mold closing device are both installed in the upper mold support. The injection molding device is used to transport molten material to the side of the upper module opposite to the lower module. The mold closing device is used to push the upper module to cooperate with the lower module for mold closing. The upper mold support includes a first base plate. The upper module is installed on the bottom surface of the first base plate. The first base plate is slidably connected to the lower mold assembly. The mold closing device is connected to the top surface of the first base plate. The mold closing device can push the first base plate to move the upper module towards the lower module. By setting the upper mold support, injection molding device, and mold closing device, the upper module in the upper mold assembly can cooperate with the lower module to form a lower stop code at the end of the previous zipper tape and at the beginning of the next zipper tape.
[0006] Preferably, the lower mold assembly includes a lower mold support, a tape feeding device, and a cooling device. The lower mold support is fixedly mounted on the machine body. The tape feeding device and the cooling device are both installed in the lower mold support. The zipper tape enters between the upper and lower modules through the tape feeding device. The cooling device is connected to the lower module and is used to control the temperature of the lower module. The upper module has a pin injection cavity, a block injection cavity, and a set of stop-code injection cavities for injection molding the upper stop code on the side facing the lower module. The pin injection cavity, block injection cavity, and stop-code injection cavity are all connected to the side of the upper module away from the lower module. The lower module has injection cavities that match those of the upper module. By setting the lower mold support, tape feeding device, and cooling device, the lower mold assembly can cooperate with the upper mold assembly to perform injection molding of the upper and lower stop codes simultaneously, and can also limit the movement of the zipper tape.
[0007] Preferably, the left worktable includes a left support base, a first force-applying component, and a second force-applying component. Both the first and second force-applying components are mounted on the left support base. The first force-applying component clamps the zipper tape with a zipper pin on one side, and the second force-applying component pushes the zipper tape with the zipper pin on one side, causing the zipper pin to move. By configuring the left support base, the first force-applying component, and the second force-applying component, the left worktable can control the movement trajectory of the zipper pin, thereby cooperating with the zipper block to complete the insertion of the lower stop block.
[0008] Preferably, the right worktable includes a right support base, a third force-applying component, and a fourth force-applying component. The third force-applying component is slidably connected to the right support base, and the fourth force-applying component is mounted on the right support base. The third force-applying component is used to clamp the zipper block, and the fourth force-applying component can push the third force-applying component to move the zipper block. By setting the right support base, the third force-applying component, and the fourth force-applying component, the right worktable can control the movement trajectory of the zipper block, and thus cooperate with the zipper pin to complete the insertion work.
[0009] Preferably, the zipper closing mechanism further includes a limiting device installed between the left and right worktables. The limiting device includes a fifth force-applying component and a positioning frame. The fifth force-applying component is rotatably connected to the positioning frame and is used to limit the zipper block during the insertion of the zipper pin into the zipper block. By setting the fifth force-applying component and the positioning frame, the limiting device can limit the zipper block, preventing misalignment of the zipper block before the zipper pin is successfully inserted due to the conveying of the zipper tape.
[0010] Preferably, the pressing device includes a reverse drive assembly and a zipper tooth engagement assembly. The zipper tooth engagement assembly is installed on the side of the reverse drive assembly opposite to the injection molding mechanism. The reverse drive assembly drives the zipper tape for conveying, and the zipper tooth engagement assembly presses down on the zipper teeth. The zipper tooth engagement assembly and the reverse drive assembly together complete the closure of the zipper teeth. By setting up the reverse drive assembly and the zipper tooth engagement assembly, the pressing device can use the conveying action of the zipper tape to engage the zipper teeth, thereby completing the zipper closure.
[0011] This invention also provides a method for molding and assembling zipper stop codes, applied to the aforementioned zipper stop code molding and assembling equipment. This method involves simultaneously injection molding the upper and lower stop codes at the tail end of the previous zipper tape and the beginning end of the next zipper tape, and assembling the zipper teeth on the lower stop code side of the zipper tape. The method mainly includes the following steps: Step S1. The tail end of the previous zipper tape and the head end of the next zipper tape are conveyed to the space between the upper module and the lower module. The upper mold assembly drives the upper module to press down. The upper module cooperates with the lower module to form a lower stop code at the tail end of the previous zipper tape and an upper stop code at the head end of the next zipper tape. After injection molding is completed, the upper mold assembly returns to its original position, and the zipper tape with the upper and lower stop codes leaves the injection molding mechanism under the action of the conveying mechanism. Step S2. The lower stop block is located between the left and right worktables. The right worktable clamps the zipper block and moves it a short distance away from the injection molding mechanism. The left worktable clamps the zipper tape with a zipper pin on one side and pushes it to move the pin to the side of the zipper block facing the injection molding mechanism. The limiting device limits the zipper block. The conveying mechanism is started until the zipper pin is inserted into the zipper block, then the conveying stops. The left and right worktables and the limiting device return to their original positions. The pressing device is started, which conveys the zipper tape towards the injection molding mechanism while pressing down on the zipper teeth to complete the engagement. Finally, the pressing device returns to its original position, and the zipper tape leaves the closing mechanism under the action of the conveying mechanism.
[0012] Preferably, step S1 includes the following steps: Step S1.1. Start the conveyor mechanism. The zipper tape begins to be conveyed. The end of the previous zipper tape and the beginning of the next zipper tape are conveyed between the upper module and the lower module. The conveyor mechanism stops conveying. Step S1.2. The injection molding device delivers the molten material to the upper module, starts the mold closing device, pushes the upper module downward, starts the cooling device, and the upper module cooperates with the lower module to perform injection molding of the lower stop code at the end of the previous zipper tape and injection molding of the upper stop code at the beginning of the next zipper tape. Step S1.3. The mold closing device drives the upper module back to its original position, starts the conveying mechanism, and the zipper tape begins to be conveyed. The zipper tape with the upper stop and lower stop is released from the injection molding mechanism under the action of the conveying mechanism.
[0013] Preferably, step S2 includes the following steps: Step S2.1. The conveying mechanism stops conveying, the first force application component clamps the zipper tape with a zipper pin on one side, the third force application component clamps the zipper block, the fourth force application component pushes the third force application component to move the zipper block a short distance away from the injection molding mechanism, the second force application component pushes the zipper tape with a zipper pin on one side to move the zipper pin to the side of the zipper block facing the injection molding mechanism, and the fifth force application component limits the side of the zipper block away from the injection molding mechanism. Step S2.2. Start the conveyor mechanism. Under the conveying action of the zipper belt, the zipper pin is inserted into the zipper block. The conveyor mechanism stops conveying, and the first force application component, the second force application component, the third force application component, the fourth force application component, and the fifth force application component return to their original positions. Step S2.3. The reverse drive assembly drives the zipper tape to be conveyed toward the injection molding mechanism. At the same time, the tooth engagement assembly presses down on the teeth. Under the conveying action of the zipper tape, the teeth mesh with each other, completing the closure of the teeth on the lower stop side of the zipper tape. The reverse drive assembly and the tooth engagement assembly return to their original positions.
[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, the upper module works with the lower module to perform injection molding of the lower stop code at the tail end of the previous zipper tape and injection molding of the upper stop code at the head end of the next zipper tape. The injection molding mechanism composed of the upper mold assembly and the lower mold assembly integrates plastic melting, melt conveying, mold closing and demolding, and cooling and molding into one unit. This solves the problem of setting up two sets of injection molding equipment or using one set of equipment to perform injection molding of the upper and lower stop codes at the head and tail ends of the zipper tape in two separate processes in the prior art, thus improving production efficiency. 2. In this invention, the left clamping platform, in conjunction with the right clamping platform and the belt drive, enables the zipper pin to be inserted into the zipper block. The limiting device can limit one side of the zipper block to prevent the zipper belt from taking the zipper block away from the right clamping platform before the zipper pin is inserted. The first roller group and the second roller group of the pressing device can lightly press and limit the zipper belt and the zipper teeth. The pressing frame combined with the belt drive can accurately close the zipper teeth, ensuring the stability of the insertion and engagement process, thereby improving the yield rate.

After the injection molding is completed, the upper mold assembly 21 returns to its original position, and the zipper tape 5 with the upper stop code 8 and the lower stop code 9 leaves the injection molding mechanism 2 under the action of the conveying mechanism 4. Step S2. The lower stop block 9 is located between the left worktable 21 and the right worktable 22. The right worktable 22 clamps the zipper block 92 and moves it a short distance away from the injection molding mechanism 2. The left worktable 21 clamps the zipper tape 5 with a zipper pin 91 on one side and pushes it to move the zipper pin 91 to the side of the zipper block 92 facing the injection molding mechanism 2. The limiting device 24 then moves the zipper block 92... The conveyor mechanism 4 is activated until the zipper pin 91 is inserted into the zipper block 92, and then the conveyor stops again. The left worktable 21, the right worktable 22, and the limit device 24 all return to their original positions. The pressing device 33 is activated. The pressing device 33 conveys the zipper tape 5 towards the injection molding mechanism 2 while pressing down on the zipper teeth 7 to complete the engagement of the zipper teeth 7. Finally, the pressing device 33 returns to its original position, and the zipper tape 5 after being closed leaves the closing mechanism 3 under the action of the conveyor mechanism 4.
[0054] Please see Figures 1 to 17 Step S1 includes the following steps: Step S1.1. Start the conveyor mechanism 4, the zipper tape 5 starts to convey, the tail end of the previous zipper tape 5 and the head end of the next zipper tape 5 are conveyed to the upper module 211 and the lower module 221, and the conveyor mechanism 4 stops conveying. Step S1.2. The injection molding device 213 delivers the molten material to the upper module 211, starts the mold closing device 214, pushes the upper module 211 downward, starts the cooling device 224, and the upper module 211 cooperates with the lower module 221 to perform injection molding of the lower stop 9 at the end of the previous zipper tape 5, and at the same time performs injection molding of the upper stop 8 at the beginning of the next zipper tape 5. Step S1.3. The mold closing device 214 drives the upper module 211 back to its original position, starts the conveying mechanism 4, and the zipper tape 5 begins to be conveyed. The zipper tape 5 with the upper stop code 8 and the lower stop code 9 leaves the injection molding mechanism 2 under the action of the conveying mechanism 4.
[0055] Specifically, step S1.1 is as follows: Start the first motor 412 (or start the second motor 422, or start the first motor 412 and the second motor 422 simultaneously), and the first drive device 41 (or the second drive device 42, or the first drive device 41 and the second drive device 42) drives the zipper tape 5 to be conveyed. The zipper tape 5 enters the guide frame 2231 through several guide wheels 2234 and arrives between the upper module 211 and the lower module 221. When the tail end of the upper zipper tape 5 and the head end of the next zipper tape 5 are both located in the injection cavity of the stop code member on the lower module 221, the first motor 412 (or the second motor 422, or the first motor 412 and the second motor 422) is turned off. Step S1.2 is as follows: The second drive component 2135 is activated. When the temperature of the heat-conducting component 2137 reaches the melting point of the plastic for injection molding, the plastic is poured in from the sprue 2131. The plastic is conveyed from the sprue 2131 to the heat-conducting component 2137 and forms molten material at the heat-conducting component 2137. The first drive component 2133 is activated. The molten material is conveyed along the thread 2132A to the bottom of the screw 2132. The third drive component 2141 and the fourth drive component 2142 are activated. The third drive component 2141 and the fourth drive component 2142 work together to push the first base plate 2121 and the first guide rod 2125, the second guide rod 2126, the third guide rod 2127 and the fourth guide rod 2128 installed around the first base plate 2121 to descend. The upper module 211 and the lower module 221 close the mold. After the molten material is filled, the cooling device 224 is activated. The cooling device 224 cools down the lower module 221. Step S1.3 is as follows: The third driving component 2141 and the fourth driving component 2142 drive the lower module 221 to demold, successfully forming a lower stop code 9 at the end of the previous zipper tape 5 and an upper stop code 8 at the beginning of the next zipper tape 5. The first motor 412 is started (or the second motor 422 is started, or the first motor 412 and the second motor 422 are started simultaneously). The first driving device 41 (or the second driving device 42, or the first driving device 41 and the second driving device 42) drives the zipper tape 5 to be conveyed. The zipper tape 5 with the upper stop code 8 and the lower stop code 9 leaves the injection molding mechanism 2.
[0056] Please see Figures 1 to 17 Step S2 includes the following steps: Step S2.1. The conveying mechanism 4 stops conveying, the first force application component 212 clamps the zipper tape 5 with a zipper pin 91 on one side, the third force application component 222 clamps the zipper block 92, the fourth force application component 223 pushes the third force application component 213 to move the zipper block 92 a short distance away from the side of the injection molding mechanism 2, the second force application component 213 pushes the zipper tape 5 with a zipper pin 91 on one side to move the zipper pin 91 to the side of the zipper block 92 facing the injection molding mechanism 2, and the fifth force application component 241 limits the side of the zipper block 92 away from the injection molding mechanism 2. Step S2.2. Start the conveyor mechanism 4. Under the conveying action of the zipper tape 5, the zipper pin 91 is inserted into the zipper block 92. The conveyor mechanism 4 stops conveying, and the first force application component 212, the second force application component 213, the third force application component 222, the fourth force application component 223, and the fifth force application component 241 return to their original positions. Step S2.3. The reverse drive assembly 331 drives the zipper tape 5 to be conveyed toward the injection molding mechanism 2. At the same time, the tooth engagement assembly 332 presses down on the teeth 7. Under the conveying action of the zipper tape 5, the teeth 7 mesh with each other, completing the closure of the teeth 7 on the side of the lower stop 9 in the zipper tape 5. The reverse drive assembly 331 and the tooth engagement assembly 332 return to their original positions.
[0057] Specifically, step S2.1 is as follows: the first power source 3121 is activated to drive the upper jaw 3123A and lower jaw 3123B in the first jaw assembly 3123 to clamp the zipper tape 5 with a zipper pin 91 on one side; the third power source 3221 is activated to drive the movable jaw 3223A in the second jaw assembly 3223 to cooperate with the fixed jaw 3223B to clamp the zipper block 92; the fourth power source 3231 is activated to push the third force application component 322 to move the zipper block 92 a short distance towards the zipper exit side; the second power source 3131 is activated and the second transmission component 3133 pushes the zipper tape 5 with a zipper pin 91 on one side to move the zipper pin 91 to the side of the zipper block 92 towards the zipper entry side; the fifth power source 3411 is activated to drive the protrusion 3413A on the top of the third transmission component 3413 to limit the zipper block 92 towards the zipper exit side. Step S2.2 is as follows: Start the second motor 422. The second drive device 42 drives the zipper tape 5 to travel a short distance. Under the conveying action of the zipper tape 5, the zipper pin 91 is successfully inserted into the zipper block 92. Then, immediately turn off the second motor 422, start the first power source 3121 to drive the first gripper group 3123 to return to its original position, start the third power source 3221 to drive the second gripper group 3223 to return to its original position, start the fourth power source 3231 to drive the third force application component 322 to return to its original position, start the second power source 3131 to drive the second transmission component 3133 to return to its original position, and start the fifth power source 3411 to drive the third transmission component 3413 to return to its original position. Step S2.3 is as follows: Simultaneously, the sixth power source 3312 is activated to slowly transport the zipper tape 5, with the lower stop code 9 threaded on, from between the left worktable 21 and the right worktable 22 to the reverse drive assembly 331. At the same time, the elastic element 3318B drives the third roller 3318C to lightly press and limit the zipper teeth 7 before engagement. Then, the seventh power source 3315 is activated to drive the first roller 3316A and the second roller 3316B in the first roller group 3316 to press the zipper tape 5 on both sides of the zipper teeth 7. A light pressure limit is applied, and the eighth power source 3322 is activated to drive the recessed part 3323A on the pressure frame 3323 to press down the chain teeth 7 before engagement. Under the conveying action of the zipper tape 5, the chain teeth 7 before engagement engage with each other after passing through the recessed part 3323A, completing the closure of the chain teeth 7. Finally, the seventh power source 3315 is activated to drive the first roller group 3316 back to its original position, and the eighth power source 3322 is activated to drive the pressure frame 3323 back to its original position, preparing for the next round of work.
