Description

Technical Field

[0001] The invention relates to a handbag production technology, in particular to a hole punching and rope threading device for handbag production. Background Art

[0002] A handbag is a simple bag made of paper, PVC laser film, non-woven industrial cardboard, etc. It is usually used by manufacturers to hold products, and is also used to hold gifts when giving gifts. Handbags are widely used in people's lives, and one of them is made of cardboard, consisting of a hand rope and a bag body. A rope threading hole is opened on the bag body, and the two ends of the hand rope pass through the rope threading hole from the outside to the inside. A plastic sleeve is provided at the end of the hand rope, and the end of the plastic sleeve is stuck in the rope threading hole to prevent the hand rope from escaping from the rope threading hole. People use the hand rope to carry things, which provides great convenience to people's lives.

[0003] However, in the production of this type of handbag, holes are punched in the handbag first, and then the rope is threaded manually, and the rope end is pulled into the handbag to avoid too much rope exposed on the outside of the handbag, which may cause the rope to become knotted or entangled, affecting the user's use of the handbag after subsequent batch packaging. The manual threading method wastes a lot of manpower and material resources, is relatively inefficient, and is prone to deformation and damage of the bag due to improper manual operation, affecting product quality.

[0006] Further, one end of the inner wall of the feeding bin is provided with a rope outlet, and one side of the feeding bin is fixedly connected with a support plate, and one side of the support plate is fixedly connected with one side of two support plates in the same perforating device.

[0007] Further, the driving mechanism includes a biaxial motor. The output ends on both sides of the biaxial motor respectively penetrate through two support plates in the same perforating device and are rotatably connected with the inner walls of the two support plates. The output ends on both sides of the biaxial motor are fixedly connected with one side of a turntable, and one side of the biaxial motor is fixedly connected with one side of the two support plates.

[0008] Further, a slider two is slidably connected to the inner wall of one end of the rotating rod. A rotating shaft is rotatably connected to the inner wall of the slider two. One end of the rotating shaft is fixedly connected with one side of the support plate. One side of the sliding rail is fixedly connected with the top of the support plate, and one end of the rotating rod penetrates through the sliding rail and is slidably connected with the inner wall of the bottom of the sliding rail.

One side of the dial rod is fixedly connected with one side of the screw rod. One sides of the two limiting columns are respectively fixedly installed at both ends of one side of the sliding rail.

[0010] Further, the rope pulling device includes a starting mechanism, a top support rod and a rope pulling head. The top support rod is installed on one side of the starting mechanism. The number of the rope pulling heads is four. One sides of the four rope pulling heads are fixedly installed on one side of the top support rod, and the four rope pulling heads are respectively located directly above the shopping bag.

[0011] Further, the starting mechanism includes an electric telescopic rod. The output end of the electric telescopic rod is fixedly connected with one side of the top support rod. Support heads are fixedly installed on both sides of the top support rod. A number of short thorns are arranged on one side of the rope pulling head.

[0012] Further, the feeding bin is U-shaped, and a U-shaped groove is provided on the feeding bin. The U-shaped groove is communicated with the rope outlet, and a number of shopping bag ropes are placed in the U-shaped groove.

[0013] Compared with the prior art, a punching and threading device for shopping bag production provided by the present invention has the following beneficial effects: 1. The punching and stringing device for producing handbags drives the turntables on both sides to rotate through the rotation of the dual-axis motor. The rotation of the turntable drives the slider 1 to slide along the inner wall of the rotating rod and makes the slider 2 slide along the inner wall of the rotating rod, thereby driving the bottom of the clamping table to slide along the top of the slide rail, so that the clamping table drives the clamping mechanism to move back and forth left and right, thereby realizing the process of reciprocating stringing of each handbag through the punching device, avoiding the problem of too much exposed rope body on the outside of the handbag causing the rope body to be knotted or entangled, thereby affecting the difficulty of users to take the handbags after subsequent batch packaging, saving manpower and material costs, improving stringing efficiency, avoiding deformation and damage of the bag body due to improper manual operation, and improving product quality.

[0014] 2. The drilling and rope threading device for handbag production enters the middle of the chuck and the splint through one end of the rope head, and the lever is driven by the limiting column to drive the screw to rotate forward by a certain angle, so that the chuck moves toward the splint and clamps one end of the handbag rope. At this time, the two clamping mechanisms on the same side respectively clamp the two ends of the same rope head and move to the side of the handbag, and finally pass the two ends of the rope head into the two holes on one side of the handbag. At this time, the lever is driven by another limiting column to drive the screw to rotate reversely by a certain angle, so that the chuck releases the clamp on one end of the handbag rope, further realizing the accuracy and accuracy of reciprocating precise clamping of the handbag rope and threading, and ensuring the reliability and efficiency of threading the handbag rope.

[0015] 3. The drilling and threading device for producing handbags continues to drive the top support rod to move downward through the electric telescopic rod, so that the four rope heads move downward. When the two ends of the hand rope enter the inner side of the handbag, the rope head presses down one end of the hand rope and hooks the connection between the plastic tube section at one end of the hand rope and the rope body through the short thorns on one side, so that the hand rope continues to enter the inner side of the handbag, and the four rope heads will operate synchronously through the perforating devices arranged on both sides, pass the two hand ropes on both sides into the handbag and pull the rope heads into the interior of the handbag, reducing the length of the hand rope exposed outside the handbag, avoiding the problem of space occupation or entanglement between rope bodies when the handbag is packed.

[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0026] Embodiment 1:

[0027] See also Figures 1 - 6, A hole punching and string threading device for handbag production, including a conveying table 1. The conveying table 1 is used to convey the processed handbags 4. The pre-treatment includes steps such as cutting, bonding, and punching. During the assembly line operation, the conveying table 1 will convey the punched handbags 4 and stop for a certain period of time after being conveyed to a designated position through the positioning sensor installed on one side of the perforating device 2. Two perforating devices 2 are symmetrically installed on both sides of the conveying table 1. The perforating device 2 includes a feeding bin 21, a driving mechanism 22, two string threading mechanisms 23, and two clamping mechanisms 24. One end of the inner wall of the feeding bin 21 is provided with a rope outlet 211. Through the setting of the rope outlet 211, each handbag rope 214 can be drawn out from the bottom of the feeding bin 21. One side of the feeding bin 21 is fixedly connected with a support plate 212. The support plate 212 is used as the main support component and is connected to an external mounting frame or fixed frame to fix the perforating device 2. The feeding bin 21 is U-shaped, and a U-shaped groove 213 is provided on the feeding bin 21. The setting of the U-shaped groove 213 is beneficial to the regular placement of the handbag ropes 214. The U-shaped groove 213 is communicated with the rope outlet 211. A number of handbag ropes 214 are placed in the U-shaped groove 213. The handbag rope 214 includes plastic pipe sections at both ends and a rope body in the middle. One side of the support plate 212 is fixedly connected to one side of two support plates 231 in the same perforating device 2. The driving mechanism 22 includes a double-shaft motor 221. The double-shaft motor 221 is controlled by an external PLC programming program. The output ends on both sides of the double-shaft motor 221 respectively penetrate through two support plates 231 in the same perforating device 2 and are rotationally connected to the inner walls of the two support plates 231. The output ends on both sides of the double-shaft motor 221 are fixedly connected to one side of a turntable 232. One side of the double-shaft motor 221 is fixedly connected to one side of the two support plates 231. The string threading mechanism 23 includes a support plate 231, a turntable 232, a rotating rod 233, a slide rail 234, and a clamping table 235. One side of the turntable 232 is rotationally connected to a slider one 236. The outer side of the slider one 236 is slidably connected to the inner wall of the rotating rod 233. One end of the rotating rod 233 is rotationally connected to the inner wall of the clamping table 235. One side of the clamping table 235 is slidably connected to the inner wall of the slide rail 234. The rotation of the turntable 232 drives the swinging of the rotating rod 233 and drives one side of the clamping table 235 to move left and right along the inner wall of the slide rail 234. One end of the inner wall of the rotating rod 233 is slidably connected to a slider two 237. The inner wall of the slider two 237 is rotationally connected to a rotating shaft. One end of the rotating shaft is fixedly connected to one side of the support plate 231. One side of the slide rail 234 is fixedly connected to the top of the support plate 231, and one end of the rotating rod 233 penetrates through the slide rail 234 and is slidably connected to the bottom inner wall of the slide rail 234. The rotation of the double-shaft motor 221 drives the turntables 232 on both sides to rotate. The rotation of the turntable 232 drives the slider one 236 to slide along the inner wall of the rotating rod 233 and makes the slider two 237 slide along the inner wall of the rotating rod 233, thereby driving the bottom of the clamping table 235 to slide along the top of the slide rail 234, so that the clamping table 235 drives the clamping mechanism 24 to perform left and right reciprocating translation;

[0028] The clamping mechanism 24 is installed on one side of the rope threading mechanism 23. The clamping mechanism 24 includes a clamping plate 241 and a chuck 242. One side of the clamping plate 241 is fixedly connected to one side of the clamping table 235, and one side of the chuck 242 is slidably connected to one side of the clamping table 235. A screw rod 243 is threadedly connected to the inner wall of the chuck 242, and one end of the screw rod 243 is rotatably connected to one side of the clamping plate 241. A limiting mechanism 25 is installed on one side of each clamping mechanism 24. The limiting mechanism 25 includes two limiting columns 251 and a lever 252. One side of the lever 252 is fixedly connected to one side of the screw rod 243. One sides of the two limiting columns 251 are respectively fixedly installed at both ends of one side of the slide rail 234. When the clamping table 235 slides to one side of the feeding bin 21, one end of the drawstring head 33 enters the middle of the chuck 242 and the clamping plate 241, and the lever 252 drives the screw rod 243 to rotate forward by a certain angle under the action of the limiting column 251, so that the chuck 242 moves towards the clamping plate 241 and clamps one end of the handle rope 214. At this time, the two clamping mechanisms 24 on the same side respectively clamp both ends of the same drawstring head 33 and move towards one side of the handbag 4, and finally pass both ends of the drawstring head 33 into two holes on one side of the handbag 4. And at this time, the lever 252 drives the screw rod 243 to rotate reversely by a certain angle under the action of the other limiting column 251, so that the chuck 242 releases the clamping of one end of the handle rope 214, realizing the effect of successively conveying the handle ropes 214 to one side of the handbag 4.

[0029] Embodiment 2:

[0030] Please refer to Figure 1 and Figure 6, this embodiment provides a technical solution based on Embodiment 1: The drawstring device 3 is installed between two perforating devices 2. The drawstring device 3 includes a starting mechanism 31, a top support rod 32, and a drawstring head 33. The top support rod 32 is installed on one side of the starting mechanism 31. There are four drawstring heads 33. One side of the four drawstring heads 33 is fixedly installed on one side of the top support rod 32, and the four drawstring heads 33 are respectively located directly above the four holes of the handbag 4. The starting mechanism 31 includes an electric telescopic rod 311. The electric telescopic rod 311 is controlled by an external PLC programming program. The output end of the electric telescopic rod 311 is fixedly connected to one side of the top support rod 32. Support heads 321 are fixedly installed on both sides of the top support rod 32. A number of short spines 331 are provided on one side of the drawstring head 33. The electric telescopic rod 311 pushes the top support rod 32 to move downward. The movement of the top support rod 32 drives the support heads 321 on both sides to move downward and open the mouth of the handbag 4. When threading, the support heads 321 can support the handbag 4, fix the handbag 4 in the current position, and facilitate the stability during threading. Immediately afterwards, the electric telescopic rod 311 continues to drive the top support rod 32 to move downward, so that the four drawstring heads 33 move downward. When both ends of the handle string 214 enter the inner side of the handbag 4, the drawstring head 33 presses down one end of the handle string 214 and hooks the connection between the plastic pipe section and the rope body end of one end of the handle string 214 through the short spines 331 on one side, so that the handle string 214 continues to enter the inner side of the handbag 4. And the four drawstring heads 33 will synchronously operate through the two perforating devices 2 provided on both sides, threading the two handle strings 214 on both sides into the handbag 4 and pulling the rope ends into the interior of the handbag 4. Finally, repeat the above operations and complete the continuous threading process of the handbag 4 through the two perforating devices 2 and the drawstring device 3, reducing the length of the handle string 214 exposed outside the handbag 4 and avoiding the problems of space occupation during packing of the handbag 4 or entanglement between the rope bodies.

[0031] Working principle: When in use, first, the bag 4 production device conveys the bag 4 with holes punched therein through the conveying platform 1 to between the two perforating devices 2. During this period, the bag 4 is accurately positioned at the designated position by the positioning sensor. A plurality of hand ropes 214 are added to the feeding bin 21 in advance, and then the double-axis motor 221 is started. The rotation of the double-axis motor 221 drives the turntables 232 on both sides thereof to rotate. The rotation of the turntable 232 drives the slider 1 236 to slide along the inner wall of the rotating rod 233 and the slider 237 to slide along the inner wall of the rotating rod 233, thereby driving the bottom of the clamping platform 235 to slide along the top of the slide rail 234. When the clamping platform 235 slides to one side of the feeding bin 21 , one end of the rope head 33 enters the middle of the clamp 242 and the clamp plate 241, and the lever 252 is driven by the limiting column 251 to drive the screw 243 to rotate forward a certain angle, so that the clamp 242 moves toward the clamp plate 241 and clamps one end of the hand rope 214. At this time, the two clamping mechanisms 24 on the same side clamp the two ends of the same rope head 33 respectively and move to the side of the handbag 4, and finally insert the two ends of the rope head 33 into the two holes on one side of the handbag 4. At this time, the lever 252 is driven by another limiting column 251 to drive the screw 243 to rotate reversely a certain angle, so that the clamp 242 releases the clamping of one end of the hand rope 214.

[0032] At the same time, the electric telescopic rod 311 in the starting mechanism 31 pushes the top support rod 32 to move downward, and the movement of the top support rod 32 drives the support heads 321 on both sides thereof to move downward and open the bag opening of the handbag 4. When threading the rope, the support heads 321 can support the handbag 4, so that the handbag 4 is fixed in the current position and the stability is facilitated when threading the rope. Then, the electric telescopic rod 311 continues to drive the top support rod 32 to move downward, so that the four rope heads 33 move downward. When the two ends of the hand rope 214 enter the handbag 4, When pulling the rope sideways, the rope head 33 presses down one end of the hand rope 214 and hooks the connection between the plastic tube section at one end of the hand rope 214 and the rope body end through the short spike 331 on one side, so that the hand rope 214 continues to enter the inner side of the handbag 4, and the four rope heads 33 will operate synchronously through the perforating devices 2 set on both sides, pass the two hand ropes 214 on both sides into the handbag 4 and pull the rope heads into the interior of the handbag 4, and finally repeat the above operation to complete the continuous rope threading process of the handbag 4 through the two perforating devices 2 and the rope pulling device 3.

[0033] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
