[0057] Casing feeding mechanism 1

[0058] like Figure 3-8 As shown, the casing feeding mechanism 1 includes a casing feeding frame 11, a casing feeding hopper 12, a climbing mechanism 13, a material shifting mechanism 14, a casing transmission mechanism 15, and a casing clamping cylinder 16;

[0059] The casing upper hopper 12 and the casing transmission mechanism 15 are respectively located on both sides of the casing loading rack 11, and the climbing mechanism 13 is located in the casing loading rack 11. The bottom of the casing upper hopper 12 is an inclined surface, and the height of the inclined surface close to the climbing mechanism 13 is the lowest; the casing is placed in batches in the casing upper hopper 12 and slides along the inclined surface to the climbing mechanism 13.

[0060] Preferably, a workbench 121 is provided on the top of the casing loading hopper 12, which can facilitate the staff to clean the casing 6 on the workbench 121, so that the casing 6 entering the casing loading hopper 12 always keeps matching the transmission direction of the casing transmission mechanism 15, avoiding batches of casing 6 from directly entering the casing loading hopper 12 in a disorderly manner, causing the casing 6 in the casing loading hopper 12 to be entangled with each other, affecting the subsequent loading of each casing one by one.

[0061] The climbing mechanism 13 includes a plurality of casing climbing plates 131 and a casing climbing cylinder 132. The bottoms of the plurality of casing climbing plates 131 are connected to the casing climbing cylinder 132. The plurality of casing climbing plates 131 are arranged in a stepped manner in the vertical direction.

[0062] The piston rod of the casing climbing cylinder 132 extends, and several casing climbing plates 131 move upward as a whole. During this process, the casings 6 in the casing upper hopper 12 fall one by one to the top of each corresponding casing climbing plate 131 and move upward with the casing climbing plate 131.

[0063] The piston rod of the casing climbing cylinder 132 is extended and retracted, and a plurality of casing climbing plates 131 can be controlled to rise and fall cyclically, so as to realize the feeding of casings 6 one by one.

[0064] The climbing mechanism 13 also includes a climbing fixed plate 133, a climbing connecting plate 134, and a limiting guide column 135; the cylinder body of the casing climbing cylinder 132 is fixed on the climbing fixed plate 133, and a plurality of casing climbing plates 131 are connected to the piston rod of the casing climbing cylinder 132 through the climbing connecting plate 134; the limiting guide column 135 is vertically connected to the climbing fixed plate 133; the climbing connecting plate 134 is provided with a guide hole 1341, and the limiting guide column 135 passes through the guide hole 1341.

[0065] Under the action of the casing climbing cylinder 132, the climbing connecting plate 134 drives several casing climbing plates 131 to rise and fall along the limiting guide column 135. The limiting guide column 135 plays a guiding role, so that the casing climbing plate 131 always keeps rising and falling on the same axis to avoid dislocation after repeated rising and falling, which affects the feeding of the casing 6.

[0066] The material-digging mechanism 14 is connected to one side of the sleeve transmission mechanism 15 through the sleeve loading frame 11. The material-digging mechanism 14 includes a material-digging cylinder 141, a material-digging connecting plate 142, a rotating shaft 143, and a material-digging plate 144. The material-digging cylinder 141 is connected to the rotating shaft 143 through the material-digging connecting plate 142. The material-digging plate 144 is "Z"-shaped, and one side of the material-digging plate 144 is connected to the rotating shaft 143.

[0067] The terminal control cabinet 8 controls the intermittent operation of the material-dispensing cylinder 141, such as Figure 7 As shown, the control shaft 143 rotates so that the material-diverting edge of the material-diverting plate 144 diverts the sleeve 6 that has risen to the target position to the sleeve transmission mechanism 15 .

[0068] The sleeve transmission mechanism 15 includes a sleeve transmission frame 151 and a transmission belt 153. The transmission belt 153 is located on the sleeve transmission frame 151. The sleeve clamping cylinder 16 is located above the transmission belt 153.

[0069] The sleeve 6 falls into the sleeve transmission frame 151 through the material selection of the material selection plate 144 and is transferred to the bottom of the sleeve clamping cylinder 16. The sleeve clamping cylinder 16 clamps the sleeve 6 from the sleeve transmission frame 151 for standby use. The sleeve transmission frame 151 can be an existing conveyor belt driven by a motor to achieve horizontal movement of the sleeve 6.

[0070] The sleeve transmission frame 151 is provided with a transmission slot 152, and the transmission belt 153 is located in the transmission slot 152. The sleeve 6 is restricted in the transmission slot 152 for transmission, so as to prevent the sleeve 6 from flying out from the side of the sleeve transmission frame 151.

[0071] The side of the sleeve transmission frame 151 is provided with a material partition plate 154. The material partition plate 154 can block the sleeve 6 moved by the material shifting mechanism 14, and prevent the sleeve 6 from flying out directly due to the unstable material shifting of the material shifting mechanism 14.

[0072] A sleeve sensing component 155 is provided at the end of the conveyor belt 153. The sleeve sensing component 155 can be an existing pressure sensor. When the end of the sleeve 6 is against the sensing area of ​​the sleeve sensing component 155, the sleeve sensing component 155 converts the sensed pressure signal into an electrical signal and transmits it to the terminal control cabinet 8. After receiving the signal, the terminal control cabinet 8 sends an instruction to the sleeve clamping cylinder 16 to realize automatic clamping of the sleeve clamping cylinder 16.

[0073] The function of the sleeve feeding mechanism 1 is to put the sleeves 6 into the sleeve feeding hopper 12 in batches, and the sleeves 6 roll to the top of each corresponding sleeve climbing plate 131 one by one. The sleeve climbing plate 131 drives each sleeve 6 to climb, and the material shifting mechanism 14 shifts the sleeves 6 that have climbed to the target position one by one to the conveyor belt 153 on one side; after the sleeves 6 are transmitted to the target position on the conveyor belt 153, they are clamped away from the conveyor belt 153 by the sleeve clamping cylinder 16.

[0074] Liner pipe feeding mechanism 2

[0075] like Figure 9-12 As shown, the inner liner tube feeding mechanism 2 includes an inner liner tube unwinding frame 21, an unwinding motor 22, and a tension adjustment mechanism 24;

[0076] The feeding end of the inner liner tube unwinding rack 21 is provided with an unwinding platform 211, and the unwinding motor 22 is connected to a transmission shaft 221, and the transmission shaft 221 is connected to the unwinding platform 211; the discharging end of the inner liner tube unwinding rack 21 is provided with a discharging pipe 26, and the tension adjustment mechanism 24 is located between the unwinding platform 211 and the discharging pipe 26;

[0077] Preferably, the discharge pipe 26 is provided with a discharge sensor 261, which can be an existing photoelectric sensor, which converts the sensed light signal into an electrical signal, thereby sending the information to the terminal control cabinet 8. The terminal control cabinet 8 can monitor the transmission status of the inner liner pipe 7 discharging in the discharge pipe 26 in real time. When the discharge sensor 261 detects that there is no transmission in the inner liner pipe 7 in the discharge pipe 26, the terminal control cabinet 8 then sends a signal, which allows the operator to discover and handle it in time.

[0078] The unwinding motor 22 drives the transmission shaft 221 to rotate, and the inner liner tube roll realizes the unwinding of the inner liner tube as the transmission shaft 221 rotates. The inner liner tube feeding mechanism 2 also includes a material pressing frame 222, which is in the shape of an "I" character, and includes a chassis 223, a pressure plate 224, a connecting column 225, and a first fastener 226. The connecting column 225 is connected to the transmission shaft 221, and the pressure plate 224 is fixed to the top of the connecting column 225 through the first fastener 226. The first fastener 226 can be a conventional nut and bolt assembly. When unwinding, the pressure plate 224 is first removed from the connecting column 225 through the first fastener 226, the liner tube is rolled onto the connecting column 225, and the pressure plate 224 is installed above the liner tube roll sleeve through the first fastener 226, so that the two sides of the liner tube roll sleeve are tightly pressed between the pressure plate 224 and the chassis 223, thereby enhancing the positioning effect of the liner tube roll during unwinding and enhancing the unwinding stability.

[0079] The tension adjustment mechanism 24 includes a feed roller 241, an intermediate roller 242, an adjustment roller 243, a discharge roller 244, and an adjustment roller sliding assembly 247; the tension adjustment mechanism 24 is located on the inner liner tube unwinding frame 21, the intermediate roller 242 is located between the feed roller 241 and the discharge roller 244, and the adjustment roller 243 is connected to the bottom of the intermediate roller 242 through the adjustment roller sliding assembly 247;

[0080] The adjusting roller sliding assembly 247 can be a combination of existing linear guides and sliders. The adjusting roller 243 is connected to the linear guide via the slider. The liner tube 7 enters the feed roller 241 and is transmitted to the middle roller 242 and the adjusting roller 243 below, and then is transmitted to the discharge roller 244. During the transmission process, the transmission tension of the liner tube 7 is constantly changing due to the operation of the assembly production line. The adjusting roller 243 can move up and down along the adjusting roller sliding assembly 247 accordingly to adjust the transmission tension of the liner tube 7.

[0081] A plurality of adjusting roller sensing devices 245 are disposed on the side of the adjusting roller sliding assembly 247 , and the plurality of adjusting roller sensing devices 245 can be respectively installed at different heights of the adjusting roller sliding assembly 247 .

[0082] The adjusting roller sensing device 245 can be a photoelectric sensor. When the adjusting roller 243 passes through the sensing area of ​​the adjusting roller sensing device 245, the adjusting roller sensing device 245 will sense the light signal and convert it into an electrical signal, and transmit it to the terminal control cabinet 8. After receiving the instruction, the terminal control cabinet 8 can adjust the position of the control target adjusting roller sensing device 245, issue corresponding instructions to the unwinding motor 22, adjust the speed of the unwinding motor 22, and cooperate with the adjusting roller 243 to adjust the tension.

[0083] Buffer rods 246 are vertically provided at both ends of the adjusting roller sliding assembly 247, and the buffer heads of the buffer rods 246 face the adjusting roller 243. The buffer heads can be rubber heads. When the lifting stroke of the adjusting roller 243 is out of control and exceeds the limit position, the adjusting roller 243 is prone to collide with other devices and cause danger. The buffer heads of the buffer rods 246 can play a buffering and limiting role on the adjusting roller 243.

[0084] An inner liner tube guide mechanism 23 is provided between the tension adjustment mechanism 24 and the unwinding platform 211. The inner liner tube guide mechanism 23 includes a guide roller 231, a transmission tube 232, and a guide ring 234. The guide roller 231 is connected to one side of the unwinding platform 211 through the inner liner tube unwinding frame 21, and the transmission tube 232 is connected between the guide roller 231 and the guide ring 234 through the inner liner tube unwinding frame 21; the discharge port of the guide ring 234 faces the feed roller 241.

[0085] The guide roller 231 guides the transmission of the newly unwound inner liner tube 7, the transmission tube 232 plays a transitional role in transmission, and the guide ring 234 can accurately guide the inner liner tube 7 to the feed roller 241. If the newly unwound inner liner tube 7 is directly transmitted to the feed roller 241, the inner liner tube 7 is more likely to fly due to the high degree of bending and the influence of the transmission speed. The inner liner tube guide mechanism 23 can guide the transmission of the inner liner tube 7 to prevent the phenomenon of flying and winding caused by the unstable transmission of the bent inner liner tube 7.

[0086] A rubber ring 235 is provided inside the guide ring 234. The guide ring 234 is generally made of relatively hard stainless steel, while the material of the inner liner tube 7 is relatively soft. When the inner liner tube 7 is transported in the guide ring 234, it is easy to bend slightly. The friction between the inner liner tube 7 and the inner wall of the guide ring 234 is easy to scratch the surface of the inner liner tube 7, affecting the yield rate of the product. The rubber ring 235 is relatively soft in texture and can protect the inner liner tube 7 that rubs against it.

[0087] The guide ring 234 is connected to the inner liner tube unwinding rack 21 through the second fastener 233, and the angle of the guide ring 234 can be quickly adjusted through the second fastener 233, so as to adjust the angle of the inner liner tube 7 entering the feed roller 241 according to the different tube diameters of the inner liner tube 7 and the online transmission conditions, thereby improving the transmission stability.

[0088] A limiting rod 25 is provided above the feed roller 241 and the discharge roller 244 through the inner liner tube unwinding frame 21, and the limiting rod 25 can effectively prevent the occurrence of flying wires.

[0089] A buffer tray 212 is provided at the bottom of the inner liner tube unwinding rack 21 , and the buffer tray 212 can reduce the shaking of the inner liner tube unwinding rack 21 .

[0090] The function of the inner liner tube feeding mechanism 2 is that the inner liner tube roll is unwound online on the unwound table 211 through the unwound motor 22, and the inner liner tube 7 is transmitted to the feed roller 241 and the middle roller 242 through the inner liner tube guiding mechanism 23, and the tension is adjusted by the adjusting roller 243. Then, the inner liner tube 7 is transmitted from the discharge roller 244 to the discharge pipe 26 and discharged for standby.

[0091] Liner pipe conveying mechanism 3

[0092] The inner liner pipe conveying mechanism 3 is an existing device. The structure and function of the inner liner pipe conveying mechanism 3 are disclosed in the Chinese utility model patent: inner liner pipe conveying device (authorization announcement number: CN 212739378U). The inner liner pipe 7 first passes through the feed guide cylinder and enters the channel between the two conveyor belts. The conveyor belt is pressed downward by the pressure roller group so that the conveyor belt contacts the inner liner pipe and the inner liner pipe 7 is conveyed forward. The inner liner pipe conveying mechanism 3 guides and transmits the unrolled inner liner pipe 7 to the assembly station and flattens it to reduce the bending degree of the pipe body and improve the accuracy of the subsequent fixed length and cutting of the inner liner pipe 7.

The sleeve clamping cylinder 16 releases the sleeve 6, and the first group of clamping components 42 clamps the sleeve 6; the transfer cylinder 412 controls the transfer frame 411 to flow in the direction of the assembly production line, and the first group of clamping components 42 brings the sleeve 6 to the pipe threading station. At the same time, the second group of clamping components 42 arrives at the bottom of the sleeve clamping cylinder 16, and clamps the second sleeve 6 like the first group of clamping components 42; the remaining clamping components 42 gradually move forward with the movement of the transfer frame 411.

[0098] Preferably, a group of clamping components 42 is provided with four clamping cylinders. Compared with the conventional two-cylinder clamping structure, the advantage is that the four-cylinder clamping structure can not only clamp the two ends of the product, but also clamp and lift the middle part of the product, so as to avoid some products being too long and causing the middle part of the product to sag, affecting the assembly accuracy.

[0113] After the hot stamping is completed, the push rod 455 is extended under the action of the initial shaping cylinder 454, and the newly hot stamped bell mouth is briefly and lightly tapped to perform the initial shaping of the bell mouth. Since the clamping cylinder clamps the sleeve 6, the liner tube 7 may be slightly pulled out of the end of the sleeve 6 during the hot stamping process, and the push rod 455 can tap the extended liner tube 7 into the sleeve 6.

[0114] (5) Testing agency 47

[0115] The detection mechanism 47 can be an existing pressure sensor. The end of the zipper wire assembly 9 with a bell-shaped mouth is thicker than the end of the zipper wire assembly 9 without a bell-shaped mouth. The pressure sensor can sense the pressure of the bell-shaped mouth on it, and convert the sensed pressure signal into an electrical signal, and transmit it to the terminal control cabinet 8, so as to detect each zipper wire assembly 9 in real time online to avoid the phenomenon of missing heat.

[0116] (6) Secondary shaping mechanism 48

The secondary shaping cylinder 481 is connected to the shaping head 482, and the shaping head 482 is provided with a shaping cavity 483. Since the newly stamped bell mouth is relatively soft, the shaping head 482 extends through the secondary shaping cylinder 481 and wraps the bell mouth in the shaping cavity 483 for final shaping.

[0118] The function of the assembly mechanism 4 is that after the clamping cylinder located at the pipe threading station clamps the sleeve 6, the liner tube 7 is sent into the sleeve 6 through the liner tube transmission mechanism 3 through the liner tube transmission pipeline 437 and the clamping hole 4321. Subsequently, the liner tube 7 is cut to a fixed length by the cutting ejector 441 and then cut off by the blade 434; then the zipper wire assembly 9 is transferred to the hot stamping mechanism 45, and the end of the liner tube 7 extending out of the sleeve 6 is hot stamped with a bell mouth, and the bell mouth is initially shaped by the initial shaping mechanism 453. Then, the zipper wire assembly 9 enters the inspection station and the bell mouth is inspected online by the inspection mechanism 47 to avoid the phenomenon of missed hot stamping.

The two discharging members 543 are connected to the rotating shaft 51 through the connecting member 544. The two discharging members 543 are arranged in parallel on both sides of the connecting member 544. When the rotating shaft 51 is rotated by the existing servo motor, the two discharging members 543 arranged in parallel can better balance the rotation of the two discharging members 543.

[0124] The discharge member 543 includes a connecting arm 5431 and a discharge hook 5432 . The discharge hook 5432 is connected to the connecting member 544 via the connecting arm 5431 . The lengths of the two discharge hooks 5432 in a single sorting assembly 542 match the positions of the two chambers of the discharge box 51 .

[0125] The function of the sorting and discharging mechanism 5 is that the terminal control cabinet 8 issues instructions to the servo motor that controls the rotation of the rotating shaft 51 according to the detection result of the bell mouth of the assembly station, controls the rotation direction of the two discharging parts 543 of the sorting component 542, and after rotating the discharging hook 5432 of one of the discharging parts 543 to the bottom of the target zipper wire component 9, rotates the discharging hook 5432 again to transfer the hooked zipper wire component 9 to the target chamber. Among them, the two discharge pieces 543 of a single sorting component 542 correspond to a single chamber respectively, that is, one of the discharge pieces 543 is responsible for transferring good products to the good product chamber, and the other discharge piece 543 is responsible for transferring defective products to the defective product chamber. The discharge hooks 5432 of the two discharge pieces 543 of the single sorting component 542 are set with different lengths, so as to realize the separate discharge of defective products and good products; and setting up multiple sorting components 542 can enhance the stability of the material transfer of the discharge hook 5432, and avoid the zipper wire component 9 from being too long, and the zipper wire component 9 falling from the discharge hook 5432 during the material transfer process.

[0126] The utility model discloses a zipper wire assembly device, which is applied to the sleeve produced by the flat wire winding and plastic coating process. The sleeve feeding mechanism 1 feeds the sleeve 6 one by one, and the inner liner feeding mechanism 2 unwinds the rolled inner liner 7 online, and adjusts the transmission tension of the inner liner 7 and flattens the inner liner 7 according to the transmission tension and the production line production situation; the clamping component 42 cooperates with the transfer mechanism 41 to first transfer the sleeve 6 to the pipe threading station, and the inner liner 7 is inserted into the sleeve 6 and fixed in length by the inner liner fixing mechanism 44, and then the inner liner is cut The cutting mechanism 43 cuts and assembles the inner lining tube 7 into a zipper wire assembly 9; then, the zipper wire assembly 9 is transferred to the hot stamping station, and after passing through the positioning mechanism 46, the hot stamping mechanism 45 hot stamps the end of the inner lining tube 7 into a bell-shaped mouth 71, and performs initial shaping on the bell-shaped mouth through the initial shaping mechanism 453. Finally, the detection mechanism 47 performs online detection on the bell-shaped mouth 71, and the sorting mechanism 54 puts good products and defective products into corresponding chambers according to the detection results. Before discharging, the secondary shaping mechanism 48 performs the final shaping on the shape of the bell-shaped mouth 71.
