[0001] The utility model relates to the technical field of woven bag cutting, in particular to a plastic woven bag cutting and conveying device. Background Art

[0002] In the production and processing of plastic woven bags, the raw materials need to be first cut into the size of woven bags by a cutting device, and then the cut woven bag raw materials can be sewn into plastic woven bags by a sewing device.

[0003] However, in the prior art, the cutting of woven bags generally uses a resistance wire for fusing and cutting. The fused edge of the woven bag is prone to sticking to the resistance wire. With the reset of the resistance wire, the woven bag may be dragged away or displaced and folded, affecting the cutting of the woven bag. For this reason, we propose a plastic woven bag cutting and conveying device. Summary of the Utility Model

[0004] The utility model provides a plastic woven bag cutting and conveying device, which solves the above-mentioned technical problems.

[0021] Embodiment 1

[0022] As Figures 1-3As shown in the figure, a plastic woven bag cutting and conveying device of the present utility model includes an H-shaped chassis 1. At both ends of the upper part of the chassis 1, driving rollers 2 are horizontally and rotatably installed. The two driving rollers 2 are drivingly connected by a crawler 3. One of the driving rollers 2 is connected to a power mechanism. The power mechanism includes a motor 12 horizontally and fixedly installed on the outer side wall of the chassis 1. The shaft of one of the driving rollers 2 penetrates through the chassis 1. The shaft of one of the driving rollers 2 and the output shaft of the motor 12 are respectively fixedly installed with pulleys 13. The two pulleys 13 are drivingly connected by a belt 14. A plurality of support rollers 4 arranged at equal intervals are horizontally and rotatably installed on the upper part of the chassis 1. The support rollers 4 are slidably matched with the lower surface of the upper layer of the crawler 3. A support block is horizontally and fixedly installed on the outer side wall of the chassis 1. A first electric push rod 5 is vertically and fixedly installed on the lower end surface of the support block. The free end of the first electric push rod 5 movably penetrates through the support block. A connecting block 6 is fixedly installed at the free end of the first electric push rod 5. Fixing bars 7 are horizontally and fixedly installed at both ends of the connecting block 6. A slot 8 that fits the fixing bar 7 is vertically opened on the outer side wall of the chassis 1. The slot 8 provides a space for the fixing bar 7 to move up and down. The fixing bar 7 movably penetrates through the slot 8. A door-shaped fixing frame 9 is fixedly installed in the middle of the side wall of the chassis 1. The fixing frame 9 is installed with a connecting plate 10 through a lifting control mechanism. The lifting control mechanism includes a second electric push rod 15 vertically and fixedly installed on the upper end surface of the fixing frame 9. The free end of the second electric push rod 15 movably penetrates through the fixing frame 9 and is fixedly connected to the upper end surface of the connecting plate 10. A horizontally arranged heating wire 11 is fixedly installed on the lower end surface of the connecting plate 10. The heating wire 11 is located between the two fixing bars 7. This device is controlled by an external control terminal. The motor 12 works intermittently. Each time it drives the crawler 3 to drive a unit length, it drives the woven bag to move a unit length. When the motor 12 pauses, the first electric push rod 5 drives the fixing bar 7 to move downward to fix the woven bag. Then the second electric push rod 15 indirectly drives the heating wire 11 to move downward for cutting, and uses components such as a limiting member 18 for limiting and fixing to ensure smooth cutting and higher quality.

[0023] Specifically, a plurality of telescopic rods 16 are vertically and fixedly installed on the edge of the lower end surface of the connecting plate 10. A fixing piece is fixedly installed on the lower end surface of the telescopic rod 16. A spring 17 is movably sleeved on the outer side wall of the telescopic rod 16. The fixing piece is located below the heating wire 11. The fixing piece can contact the woven bag prior to the heating wire 11 and is assisted in fixing by the extrusion of the spring 17, making the fixing effect of the woven bag better.

[0024] More specifically, a plurality of inverted L-shaped limit members 18 are fixedly installed on the inner side walls of both sides of the chassis 1. A limiting piece 19 fixed to the outer side wall of the limit member 18 is arranged above the crawler belt 3. The limit member 18 is in sliding fit with the outer side wall of the crawler belt 3. The limit member 18 can limit the crawler belt 3 and the woven bags on the upper surface of the crawler belt 3, prevent the crawler belt 3 and the woven bags from shifting, ensure the cutting quality, and the limiting piece 19 can limit the woven bags to make the woven bags flatter. At the same time, the lower surface of one end of the limiting piece 19 is wedge-shaped to facilitate the passage of the woven bags.

[0025] Working principle:

[0026] During use, the starting device is controlled to make the motor 12 work intermittently. The motor 12 drives the directly connected pulley 13 to rotate. The pulley 13 and the belt 14 cooperate to drive the coaxial transmission roller 2 to rotate indirectly. The transmission roller 2 cooperates to drive the crawler belt 3 to move. The uncut woven bags are placed on the crawler belt 3, and the crawler belt 3 drives the woven bags to move forward. When the motor 12 indirectly drives the crawler belt 3 to move a unit length and then temporarily stops, at this time, the first electric push rod 5 shortens to drive the connecting block 6 and the fixing strip 7 to move downward. The fixing strip 7 cooperates with the crawler belt 3 to squeeze and fix the woven bags. Then, the second electric push rod 15 extends to drive the connecting plate 10 to move downward. As the connecting plate 10 moves downward, the fixing piece at the lower end of the telescopic rod 16 first contacts the woven bags to assist in squeezing and fixing, and then the high-temperature resistance wire 11 contacts the woven bags to realize the fusing and cutting of the woven bags. Then, the second electric push rod 15 resets first, and then the first electric push rod 5 resets to release the woven bags. The motor 12 starts again to drive the crawler belt 3 to move, and the above steps are repeated for cutting again, and so on for continuous operation.

[0027] The above is only the preferred embodiment of the present invention, and it is not intended to limit the present invention in any form; any ordinary technician in the industry can smoothly implement the present invention according to the description in the accompanying drawings and the above description; however, any equivalent changes made by those skilled in the art within the scope of the technical solution of the present invention by using the technical content disclosed above, such as making some changes, modifications and evolutions, are all equivalent embodiments of the present invention; at the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention still fall within the protection scope of the technical solution of the present invention.
