Description

Technical Field

[0001] The present invention relates to the technical field of woven bags, and in particular to a method for processing composite woven bags. Background Art

[0002] Woven bags are a common packaging material with a wide range of applications. They are generally made of plastic, extruded and stretched into flat yarns that are then woven. In the prior art, to increase the waterproofness of woven bags and prevent items inside from getting damp, a plastic liner is often added to the woven bag. After the woven bag is placed over the plastic liner, the opening of the woven bag and the opening of the plastic liner are hot-stamped and bonded together to form a composite woven bag. Composite woven bags have both the weighing capacity of woven bags and the waterproof effect of plastic bags, leading to an increasing use of composite woven bags. However, the following problems still exist in the production of composite woven bags:

[0003] 1. In the prior art, when putting a woven bag on a plastic liner, the opening of the plastic liner is generally opened manually, the plastic liner is put on the bracket, and then the opening of the woven bag is opened and the woven bag is put on the outside of the plastic liner. Finally, the woven bag and the plastic liner are removed together to complete the installation of the plastic liner. This installation method is inefficient and consumes a lot of manpower.

[0004] 2. In the prior art, when putting a woven bag on a plastic liner, the plastic liner needs to be put on a bracket first. Therefore, the bracket cannot stretch the plastic liner tightly, so that when the woven bag is put on the plastic liner, the plastic liner will have wrinkles, which will reduce the strength of the plastic liner during use and affect the quality of the composite woven bag.

[0005] 3. In the prior art, when a woven bag is put on a plastic liner, the outside of the plastic liner is generally not cleaned. If hard impurities are stuck on the outside of the plastic liner, the strength of the composite woven bag will be reduced during use.

[0006] 4. In the prior art, when preparing composite woven bags, the woven bag is generally put on the plastic liner first, and then the openings of the woven bag and the plastic liner are hot-stamped. Since the openings of the woven bag and the plastic liner need to be opened when putting on the bag, and the openings also need to be opened when hot-stamping, the two processes need to complete the same action during the process, which leads to low efficiency.

[0007] 5. In the prior art, when hot-stamping the openings of the woven bag and the plastic liner, the openings of the woven bag and the plastic liner need to be placed on the hot-stamping plate, so that the hot-stamping plate cannot open the openings, causing the openings to shrink after hot-stamping, thereby affecting the use of the composite woven bag.

[0025] Beneficial effects

[0026] Compared with the prior art, the technical solution of the present invention has the following advantages:

[0027] 1. By setting a clamping component with an upper suction cup and a lower suction cup, vacuum is drawn inside the upper suction cup and the lower suction cup, and the plastic liner and the woven bag can be sucked by the upper suction cup and the lower suction cup, and then the plastic liner and the woven bag can be pulled out and the opening can be opened by the clamping component, thereby driving the plastic liner and the woven bag to be put into the bag, which is completed automatically and saves manpower;

[0028] 2. By using the reversing slider to control the movement of the cam, and by using the first cylinder to drive the reversing slider to move, the track coordinated with the fixture can be changed, thereby changing the movement trajectory of the cam, so that the clamping component can drive the plastic liner to be sleeved on the support component, and can also drive the woven bag to be sleeved on the plastic liner. In addition, the composite woven bag that has been hot-stamped together can be removed and placed into the collection bin. The processing action can be completed without manpower, saving manpower;

[0029] 3. By providing an expandable support component, when the plastic liner and the woven bag are put on each other, the support component is closed to facilitate the putting of the plastic liner and the woven bag. When the hot ironing treatment is performed, the support component is opened to flatten the wrinkles on the plastic liner, so that the woven bag and the plastic liner can fit more closely. In addition, since the support component is opened during hot ironing, the openings of the plastic liner and the woven bag are opened, thus avoiding the phenomenon of shrinkage of the openings during hot ironing.

[0030] 4. By introducing high-pressure air into the upper and lower suction cups, after the plastic liner is put on the support assembly, when the clamping assembly is controlled to retreat, the air ejected from the upper and lower suction cups can clean the surface of the plastic liner and blow away impurities that fall on the surface of the plastic liner, thereby ensuring the quality of the composite woven bag.

[0052] In the above S1 of this embodiment, when the woven bag is placed into the lower hopper 12, the door panel 14 is opened to overcome the first spring 16 to press down the top plate 15, and the woven bag is placed on the top plate 15 with the opening facing right at the lower notch 12a, so that the woven bag is placed into the lower hopper 12.

[0053] In the above S2 of this embodiment, when the clamping assembly is working, as shown in FIG. Figure 1 The figure shows the initial position of the present invention. First, all the upper suction cups 212 and the lower suction cups 211 are evacuated so that the lower suction cups 211 suck the plastic liner. Then, the first electric push rods 3 on both sides are controlled to extend, driving the cam 241 to move. Since the end of the cam 241 slides in the upper track groove 172, the cam 241 slides along the direction of the upper track groove 172. When the cam 241 slides to a certain height, the upper cylinder 232 is controlled to extend, so that the upper suction cup 212 is rotated and sucked above the plastic liner. Since the positioning ball 32 cooperates in the positioning hole 252, the groove wheel 25 and the telescopic end of the first electric push rod 3 are positioned and do not rotate. When the upper boss 181 enters the notch of the groove wheel 25, it drives the groove wheel 25 to rotate 90°.

[0054] In the above S3 of this embodiment, after the plastic liner is put on, air is blown into the upper suction cup 212 and the lower suction cup 211, and then the first air electric push rod 3 contracts, driving the convex shaft 241 to move to the right along the first track groove 171, so that the air blown out from the upper suction cup 212 and the lower suction cup 211 blows away the impurities on the outer layer of the plastic liner, thereby completing the cleaning.

[0055] In the above S4 of this embodiment, when the clamping assembly sets the woven bag, the upper suction cup 212 and the lower suction cup 211 are controlled to stop blowing, the first cylinder 71 is controlled to contract, and the reversing slider 72 is driven to move upward to the upper end position, so that the lower connecting groove 722 connects the first track groove 171 and the lower track groove 173 to form a smooth track, and the first electric push rod 3 is controlled to continue to contract, thereby driving the convex shaft 241 to pass through the first track groove 171 and the lower connecting groove 722 into the lower track groove 173. The upper suction cup 212 is placed horizontally until the upper suction cup 212 contacts the woven bag in the lower bin 12, and then the upper suction cup 212 and the lower suction cup 211 are evacuated. The woven bag is sucked, and the first electric push rod 3 is controlled to extend, driving the convex shaft 241 to slide along the lower track groove 173 to pull out the woven bag. When the convex shaft 241 moves to a certain height, the lower cylinder 231 is controlled to extend, so that the lower suction cup 211 sucks the woven bag, and then the groove wheel 25 passes through the next convex column 183 and the lower two convex columns 184, driving the convex shaft 241 to rotate 180 degrees, thereby driving the opening of the woven bag to flip 180 degrees, and then controlling the upper cylinder 232 and the lower cylinder 231 to retract The upper suction cup 212 and the lower suction cup 211 drive the opening of the woven bag to open, and the first electric push rod 3 continues to extend, driving the convex shaft 241 to pass through the lower track groove 173 and the lower connecting groove 722 into the first track groove 171, and the woven bag is put on the outside of the plastic liner until the woven bag is completely put in. The upper suction cup 212 and the lower suction cup 211 stop exhausting air, and the first electric push rod 3 is controlled to retract, so that the convex shaft 241 moves to the right, giving up the left side, and completing the woven bag.

[0056] In the above S5 of this embodiment, when the ironing assembly is working, the upper cylinder 61 and the lower cylinder 62 are controlled to extend, driving the upper ironing plate 63163 and the lower ironing plate 6316a to move toward the middle. When the pressing plate 631 on the upper ironing plate 63163 touches the upper end of the slide plate 5, the slide plate 5 is pushed to overcome the second spring 53 and move downward, and the front support plate 412 and the rear support plate 411 are pushed to slide to both sides through the front connecting rod 521 and the rear connecting rod 522, thereby expanding the plastic liner to prevent Wrinkles appear, and at the same time, the opening is stretched open to avoid shrinkage after hot ironing. When the upper hot pressing plate 63163 and the lower hot pressing plate 6316a are buckled together, they cooperate with the front support plate 412 and the rear support plate 411 to hot iron the plastic lining and the opening of the woven bag together, and then control the upper cylinder 61 and the lower cylinder 62 to shrink. Under the action of the second spring 53, the front support plate 412 and the rear support plate 411 are driven to shrink and slide inward, so that the plastic lining is relaxed, completing the hot ironing treatment of the opening.

[0058] In the above S7 of this embodiment, the first electric push rod 3 is controlled to extend, and the cam 241 enters the first track groove 171 through the middle connecting groove 723. The upper connecting groove 721 is controlled by the first cylinder 71 to connect with the first track groove 171 and the upper track groove 172. The first electric push rod 3 is controlled to retract, so that the cam 241 enters the upper track groove 172 through the upper connecting groove 721. Then, the cam 241 is rotated 180° through the upper two protrusions 182 and the upper protrusion 181.
