Description

Technical Field

[0001] The invention belongs to the field of zipper machine equipment and relates to automatic zipper production equipment and a production process thereof. Background Art

[0002] In traditional zipper production, the zipper threading machine first puts the slider on the chain belt, and then sorts the chain belt with the slider on it and sends it to the injection molding machine. After the injection molding machine has molded the top and bottom stops, the chain belt needs to be sorted again and sent to the cutting machine for cutting. This method increases the time for sorting the belts, consumes a lot of labor costs, and the equipment is scattered and occupies a large space. Summary of the invention

[0003] In view of the above problems, the present invention provides an automatic zipper production device and a production process thereof, which has the advantages of high production efficiency and small space occupation.

[0004] The object of the present invention is achieved in that:

[0005] An automatic zipper production device comprises a frame, on which a zipper threading machine, an injection molding machine and a chain cutting machine are arranged in sequence, a chain adjustment detection device is arranged between the zipper threading machine and the injection molding machine, and an injection port waste material removal device is arranged between the injection molding machine and the chain cutting machine;

[0006] The zipper threading machine comprises a first chain belt traction mechanism, a slider conveying mechanism, an upper slider mechanism and a slider threading mechanism;

[0007] The first chain belt traction mechanism sends the chain belt with the pull head into the chain belt adjustment and detection device;

[0008] The injection molding machine comprises a knife edge detection mechanism, an injection molding mechanism and a second chain belt traction mechanism;

[0009] The second chain belt traction mechanism sends the chain belt that has completed injection molding to the injection port waste removal device;

[0010] The chain belt cutting machine comprises a knife edge positioning mechanism, a cutting mechanism and a material pulling and releasing mechanism.

[0011] Through the above settings, after the chain belt passes through the zipper threading machine and the puller is put on, the chain belt with the puller is sent to the chain belt adjustment detection device through the first chain belt traction mechanism, and automatically enters the injection molding machine after passing through the chain belt adjustment detection device. After the injection molding is completed, the molded chain belt is sent to the injection port waste removal device through the second chain belt traction mechanism, and the injection port waste removal device removes the injection port waste and sends it to the chain belt cutting machine. Finally, the cut chain belt is sent to the discharge table through the pulling and discharging mechanism, realizing the automation of the entire production process, without the need for manual belt sorting, saving a lot of labor costs, and increasing production efficiency. In addition, such a setting can integrate equipment and save factory space.

[0012] The present invention is further configured as follows: the injection port waste removal device includes a fixed plate, a waste channel is vertically opened on the fixed plate, the waste channel is opened below, a chain belt clamping mechanism is provided on one side of the fixed plate, and a waste removal mechanism is provided on the other side of the fixed plate.

[0013] Through the above settings, the chain belt after injection molding passes through the fixed plate from bottom to top, and the waste from the injection molding port enters the waste channel through the lower opening. Then the chain belt clamping mechanism presses the chain belt onto the fixed plate, and then the waste removal mechanism removes the waste from the injection molding port. Only when the waste from the injection molding port is removed can the subsequent cutting action be completed to complete the automatic production process.

[0014] The present invention is further configured as follows: the waste removal mechanism comprises two clamping plates, a clamping plate cylinder driving the two clamping plates to perform opening and closing movements, and a displacement cylinder driving the clamping plate cylinder to move.

[0015] Through the above settings, the displacement cylinder moves the splint cylinder into position, and then the splint cylinder drives the splint to clamp the injection port waste, and then the displacement cylinder drives the splint cylinder away from the fixed plate to remove the injection port waste, and then the splint cylinder releases the splint to let the injection port waste fall into the waste bucket.

[0016] The present invention is further configured as follows: an avoidance cylinder is also fixed to the output end of the displacement cylinder, and the output end of the avoidance cylinder is fixedly connected to the clamping cylinder.

[0017] By setting up the avoidance cylinder, after the displacement cylinder drives the splint cylinder away from the fixed plate to remove the waste from the injection port, the avoidance cylinder drives the splint cylinder to move forward and backward, so that the splint leaves the running path of the chain belt, avoiding the waste and chain belt from being entangled and affecting subsequent production.

[0018] The present invention is further configured as follows: the chain belt pressing mechanism includes a pressing plate and a pressing plate cylinder.

[0019] The present invention is further configured as follows: a waste detection switch is provided on the waste channel.

[0020] By setting the waste detection switch, the position of the waste at the injection port can be located more accurately.

[0021] The present invention is further configured as follows: the chain belt adjustment detection device includes two guide rods, both guide rods are provided with sliders, a buffer rod is connected between the two sliders, the lower end of the guide rod is provided with an over-slow detection switch, and the upper end of the guide rod is provided with an over-fast detection switch.

[0022] Through the above settings, the chain belt coming out of the zipper threading machine bypasses the buffer rod and then enters the injection molding machine. The chain belt presents a "U" shape. Because the buffer rod will straighten the chain belt downward under the action of gravity, when the injection molding machine speed is too fast or the zipper threading machine fails, the buffer rod will rise. After the over-fast detection switch detects the buffer rod for a certain period of time, the injection molding machine is controlled to stop working, and the injection molding machine is resumed after the buffer rod drops; when the zipper threading machine runs too fast or the injection molding machine fails, the buffer rod will drop. After the over-slow detection switch detects the buffer rod for a certain period of time, the zipper threading machine is controlled to stop working, and the zipper threading machine is resumed after the buffer rod rises.

[0023] The present invention is further configured as follows: a linear bearing is provided in the sliding block, and a sliding fit is achieved with the guide rod through the linear bearing.

[0024] The present invention is further configured as follows: the chain belt cutting machine includes a chain belt plate, a knife seat is provided at the front end of the chain belt plate, a knife head is provided on the knife seat, an ultrasonic cutter is provided at the upper end of the knife head, the knife seat is divided into a left knife seat and a right knife seat, an installation gap is provided between the left knife seat and the right knife seat, a hook needle is provided in the installation gap, a hook needle up and down driving device is provided below the chain belt plate, and a hook needle sensing switch for detecting the hook needle position is provided.

[0025] The hook needle is set between the two knife seats. When the material pulling and unloading mechanism pulls the chain belt forward, the knife edge sensing switch on the knife edge positioning mechanism detects the knife edge position, and then controls the hook needle up and down driving device to raise the hook needle so that the hook needle is hooked at the knife edge position. Then the material pulling and unloading mechanism continues to pull the chain belt forward, and the knife edge of the chain belt moves the hook needle forward. When the hook needle sensing switch senses that the hook needle has moved into place, the chain belt cutting mechanism is controlled to cut off the chain belt, and then the material pulling and unloading mechanism pulls the chain belt onto the unloading table.

[0026] The present invention is further configured as follows: the material pulling and unloading mechanism includes a material unloading table, on which a driving wheel and a passive wheel are provided, the driving wheel and the passive wheel are connected by a synchronous belt, the driving wheel is driven by a motor, the synchronous belt is fixed with a connecting plate, a grabbing plate cylinder is fixed on the connecting plate, two grabbing plates are provided at the output end of the grabbing plate cylinder, and the grabbing plate cylinder drives the two grabbing plates to perform opening and closing movements.

[0027] A zipper automatic production process comprises the following steps:

[0028] 1) Injection mold the fabric belt with the sprocket teeth to form a chain belt with sprocket teeth;

[0029] 2) Align the sprocket teeth;

[0030] 3) Pull the chained belt into the zipper threading machine and put the slider on the chain belt;

[0031] 4) The chain belt is pulled into the chain belt adjustment and detection device through the first chain belt pulling mechanism;

[0032] 5) The chain belt bypasses the buffer rod of the chain belt adjustment detection device, and the running speed of the zipper threading machine and the injection molding machine are adjusted through the too slow detection switch and the too fast detection switch;

[0033] 6) The second chain belt traction mechanism sends the chain belt that has passed the chain belt adjustment detection device into the injection molding machine to complete the injection molding of the upper stop and the lower stop of the chain belt;

[0034] 7) The second chain belt traction mechanism sends the completed chain belt to the injection port waste removal device;

[0035] 8) The waste material removal device of the injection molding port removes the waste material of the injection molding port, and then enters the chain belt cutting machine;

[0036] 9) The chain belt cutting machine cuts the chain belt as required through the knife head and ultrasonic cutter, and sends the cut chain belt to the discharge table through the pulling and discharging mechanism.

[0037] Compared with the prior art, the present invention has the following outstanding and beneficial technical effects: after the chain belt is put on the puller by the zipper threading machine, the chain belt with the puller is sent to the chain belt adjustment detection device through the first chain belt traction mechanism, and automatically enters the injection molding machine after passing through the chain belt adjustment detection device. After the injection molding is completed, the molded chain belt is sent to the injection port waste removal device through the second chain belt traction mechanism, and the injection port waste removal device removes the injection port waste and sends it to the chain belt cutting machine.

[0054] The zipper threading machine 1 comprises a first chain belt traction mechanism 11, a slider conveying mechanism 12, an upper slider mechanism 13 and a slider threading mechanism 14;

[0058] The chain belt cutting machine 3 includes a blade positioning mechanism 31 , a cutting mechanism 32 and a material pulling and releasing mechanism 33 .

[0059] The zipper threading machine 1 and the injection molding machine 2 are both prior art, and this patent will not go into details. After the chain belt is put on the pull head through the zipper threading machine 1, the chain belt with the pull head is sent to the chain belt adjustment detection device 4 through the first chain belt traction mechanism 11, and automatically enters the injection molding machine 2 after passing through the chain belt adjustment detection device 4. After the injection molding is completed, the molded chain belt is sent to the injection port waste removal device 5 through the second chain belt traction mechanism 23. The injection port waste removal device 5 removes the injection port waste and sends it to the chain belt cutting machine 3. Finally, the cut chain belt is sent to the discharge table through the pulling and discharging mechanism 33, realizing the automation of the entire production process, without the need for manual belt sorting, saving a lot of labor costs, and increasing production efficiency. In addition, such a setting can integrate the equipment and save factory space.

[0060] The injection port waste material removal device 5 comprises a fixed plate 51, the fixed plate 51 is vertically provided with a waste material channel 52, the lower part of the waste material channel 52 is open, a chain belt pressing mechanism is provided on one side of the fixed plate 51, and a waste material removing mechanism is provided on the other side of the fixed plate 51. Through the above arrangement, the chain belt after injection molding passes through the fixed plate 51 from the bottom to the top, the injection port waste material enters the waste material channel through the lower opening, and then the chain belt pressing mechanism presses the chain belt on the fixed plate 51, and then the waste material removing mechanism removes the injection port waste material. Only when the injection port waste material is removed can the subsequent cutting action be completed, and the automatic production process is completed.

[0061] The waste material removal mechanism includes two clamping plates 53, a clamping plate cylinder 54 driving the two clamping plates 53 to open and close, and a displacement cylinder 55 driving the clamping plate cylinder to move. Through the above arrangement, the displacement cylinder 55 moves the clamping plate cylinder 54 to a position, and then the clamping plate cylinder 54 drives the clamping plate 53 to clamp the injection port waste material, and then the displacement cylinder 55 drives the clamping plate cylinder 54 away from the fixed plate 51 to remove the injection port waste material, and then the clamping plate cylinder 54 releases the clamping plate 53 to allow the injection port waste material to fall into the waste material bucket.

[0062] The output end of the displacement cylinder 55 is also fixed with an avoidance cylinder 56, and the output end of the avoidance cylinder 56 is fixedly connected to the clamping plate cylinder 54. Through the arrangement of the avoidance cylinder, after the displacement cylinder 55 drives the clamping plate cylinder away from the fixed plate to remove the waste material at the injection port, the avoidance cylinder 56 drives the clamping plate cylinder 54 to move forward and backward, so that the clamping plate leaves the running path of the chain belt, thereby preventing the waste material and the chain belt from being entangled and affecting subsequent production. The chain belt pressing mechanism includes a pressing plate 57 and a pressing plate cylinder 58.

[0063] The waste channel is provided with a waste detection switch 59. By providing the waste detection switch 59, the position of the waste at the injection port can be more accurately located.

With the above arrangement, the chain belt coming out of the zipper threading machine bypasses the buffer rod 43 and then enters the injection molding machine. The chain belt presents a "U" shape. Because the buffer rod 43 will straighten the chain belt downward under the action of gravity, when the injection molding machine speed is too fast or the zipper threading machine fails, the buffer rod 43 will rise. After the over-fast detection switch 45 detects the buffer rod 43 for a certain period of time, the injection molding machine 2 is controlled to stop working, and the injection molding machine is restored after the buffer rod 43 drops; when the zipper threading machine runs too fast or the injection molding machine fails, the buffer rod 43 will drop.

The hook needle 306 is set between the two knife seats. When the material pulling and discharging mechanism 33 pulls the chain belt forward, the knife edge sensing switch on the knife edge positioning mechanism 31 detects the knife edge position, and then controls the hook needle upper and lower cylinders 307 to lift the hook needle 306 so that the hook needle is hooked at the knife edge position, and then the material pulling and discharging mechanism 33 continues to pull the chain belt forward, and the knife edge of the chain belt moves the hook needle forward. When the hook needle sensing switch 308 senses that the hook needle has moved into place, the chain belt cutting mechanism 32 is controlled to cut the chain belt, and then the material pulling and discharging mechanism 33 pulls the chain belt onto the discharging table.
