Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figure 1-16 The present invention provides a technical solution: an automatic production line for EVA zipper stationery bags, comprising: a feeding mechanism 1, a zipper tape welding high-frequency equipment 2, a zipper snapping mechanism 3, a finished product welding high-frequency equipment 4, a feeding conveyor line 5, and a unloading mechanism 6; The feeding mechanism 1 connects to the zipper belt welding high-frequency equipment 2 on the right side, the zipper belt welding high-frequency equipment 2 connects to the zipper snapping mechanism 3 on the right side, the zipper snapping mechanism 3 connects to the material pulling conveyor line 5 on the right side, the material pulling conveyor line 5 crosses the finished product welding high-frequency equipment 4, and the material pulling conveyor line 5 connects to the unloading mechanism 6 on the right side. The feeding mechanism 1 is used to fix the material roll and control the feeding tension. It outputs the zipper tape to the zipper tape welding high-frequency equipment 2. The zipper tape welding high-frequency equipment 2 fuses the EVA zipper tape with the sheet material through high frequency. The zipper snapping mechanism 3 installs the zipper head that matches the zipper onto the zipper tape through a mold. The material conveying line 5 pulls the welded zipper tape and the material with the zipper head attached to the finished product welding high-frequency equipment 4 for finished product welding. The finished product welding high-frequency equipment 4 uses high frequency to weld through a mold and cut out the product shape and holes. The unloading mechanism 6 rolls up the waste scraps and sends the finished product out of the production line for storage.

[0021] The feeding mechanism 1 includes a feeding frame 11, and a first air shaft 13, a second air shaft 14 and a third air shaft 15 are provided in the feeding frame 11, collectively referred to as air shafts. A first material roll 16, a second material roll 17 and a zipper belt roll 18 are respectively provided on the three air shafts. A belt tension supplementation mechanism 12 is installed above the feeding frame 11. The belt tension supplementation mechanism 12 includes a highly movable belt tension roller 121. The belt passes under the belt tension roller 121. Two hardened optical shafts with chrome coating are mounted on both sides of the belt tension roller 121. They slide up and down through linear bearings. The hardened optical shafts use one magnetic powder with a tension less than that of the belt tension roller 121 and the other magnetic powder with a tension greater than or equal to that of the belt tension roller 121 to supplement and balance the tension.

[0022] The first roll 16 and the second roll 17 are the bottom and the top of the EVA zipper stationery bag, respectively. The air shaft of the roll is fixed with a magnetic powder tension brake. After the two rolls pass through the set guide rollers, they meet at the tension supplement mechanism 12. When the tension error between the air shafts of the two rolls is too large and the material sheets are not tight, the tension supplement mechanism 12 will supplement and balance the tension in time. The high-frequency welding equipment 2 for zipper tape includes a welding table 21. A lifting welding device 22 is installed above the welding table 21. A zipper tape separation guide mechanism 23 and a material tape fixing cylinder assembly 231 are respectively installed on the left and right sides of the welding table 21.

The cabinet is also equipped with a touch screen 36. After the zipper belt is clamped and welded by the material conveying cylinder assembly 31, it is transferred to the sheet flipping mechanism 32 to ensure that the sheet direction is consistent in the reverse sheet flipping direction. Then, it passes through the first correction structure 33 to prevent material deviation. Then, it passes through the zipper fastening roller 34 to install the zipper head that matches the zipper onto the zipper belt through a mold. Then, it passes through the second correction structure 35 for correction and is introduced into the material conveying line 5.

[0024] The conveyor belt cylinder assembly 31 includes a linear cylinder 313 and a slide rail 311. A platform 312 is slidably mounted on the slide rail 311. A lifting drive cylinder 314 is mounted on the platform 312. A pressure block 315 is fixedly mounted on the telescopic end of the lifting drive cylinder 314. The pressure block 315 is located above the platform 312. The platform 312 is connected to the telescopic end of the linear cylinder 313. The zipper belt passes between the pressure block 315 and the platform 312. The lifting drive cylinder 314 drives the pressure block 315 to descend and cooperate with the platform 312 to clamp the zipper belt. Then, the linear cylinder 313 retracts, pulling the platform 312 to move from left to right, thereby realizing the movement of the zipper belt.

[0025] The sheet flipping mechanism 32 includes a first support frame 321. A first guide roller 322 and a counter-rotating roller 325 are provided on the side of the first support frame 321 that interfaces with the material conveyor cylinder assembly 31.

The axis of the swing shaft 3242 intersects the axis of the diagonal shaft 3231. When the sheet moves towards the fixed longitudinal shaft 3241 through the swing shaft 3242, the bottom surface is flipped. After passing through the diagonal shaft 3231, it returns to the parallel direction of the incoming material, so as to achieve the effect of sheet reversal and material edge alignment. The first correction structure 33 and the second correction structure 35 are mirror images of each other on both sides of the zipper snap roller 34. The first correction structure 33 includes two guide rollers 331 and a fixed support base 333. The guide rollers 331 are located on the left side of the support base 333. A correction guide mechanism 335 is provided on the upper surface of the support base 333. Parallel double rollers 332 are provided on the correction guide mechanism 335.

The material pulling clamps 52 are used to clamp and pull the zipper tape through the finished product welding high-frequency equipment 4. The material pulling clamps 52 have the same structure as the material tape transfer cylinder assembly 31.

[0028] A finished product waste separation mechanism 54 is installed on the material pulling clamp 52 located on the right side of the finished product welding high-frequency equipment 4. The finished product waste separation mechanism 54 includes a Y-axis cylinder 544, which is fixedly installed.

The zipper tape is output from the zipper tape roll 18, and after being separated and guided by the zipper tape separation and guide mechanism 23, it enters the zipper tape welding high-frequency equipment 2. The zipper tape welding high-frequency equipment 2 welds the zipper tape to the material strips. During the welding process, one end of the material is pressed and fixed by the material strip fixing cylinder assembly 231, and then the material strip transfer cylinder assembly 31 clamps and transfers it to the sheet flipping mechanism 32. The sheet flipping mechanism 32 ensures that the sheet direction is consistent for the reverse sheet flipping direction. Then, the material is prevented from shifting by the first correction structure 33, and then the zipper snap roller 34 loads the zipper head that matches the zipper onto the zipper belt. During this process, the zipper head feeding mechanism 37 feeds the zipper head. After assembly, the zipper belt is corrected by the second correction structure 35 and then introduced into the material conveying line 5. The material conveyor line 5 transports the zipper belt through the finished product welding high-frequency equipment 4. The high-frequency welding is used to weld the product shape and cut out the holes through the mold. The finished product is output by the finished product output line 61, and the waste belt is grabbed by the finished product waste separation mechanism 54 and sent to the waste winding auxiliary component 62, and then recycled by the automatic winding roller 63.
