Description

Technical Field

[0001] This utility model relates to the field of woven bag production equipment, and in particular to a fully automatic woven bag cutting and sewing machine. Background Technology

[0002] Woven bags, also known as snake-skin bags, are a type of plastic bag used for packaging. Their raw materials are generally polyethylene, polypropylene, and other chemical plastics. Woven bags have a wide range of uses, mainly for packaging various items. They are widely used in industry. During the production and processing of plastic woven bags, a cutting and sewing machine is used to sequentially cut and sew the bags. The rolled-up woven bag is released, the ends of the bag are cut first, then the transport direction of the bag is changed, and one side of the bag is sewn to seal the bottom. Finally, the bag is discharged and collected. When the rolled-up woven bag is gradually released, its position may shift forward or backward; excessive shift can affect the cutting and sewing process. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of existing technology and provide a fully automatic woven bag cutting and sewing machine. It can automatically feed materials, freeing up manual feeding, and can work continuously, saving time and labor. The placement mechanism moves the material according to the force applied to it, and combined with a tension control mechanism and an anti-deviation mechanism, it prevents material offset and ensures the material remains flat during the cutting and conveying process. By adjusting the spacing of a pair of baffles in the anti-deviation mechanism, it can be adapted to woven bags of different widths. The transfer mechanism, anti-tilting mechanism, and downward conveying mechanism can prevent the material from shifting after cutting, facilitating subsequent sewing work.

[0011] Furthermore, the downward conveying mechanism includes a mounting frame, one end of which is fixedly mounted on the rear end of the frame of the cutting mechanism, and the other end of which is fixedly mounted on the rear end of the support of the sewing worktable. Lower support wheels are evenly distributed on both sides of the lower end of the mounting frame, and upper support wheels are provided in the middle of the upper ends of both sides of the mounting frame. Both the lower and upper support wheels include a wheel rod and a support wheel rotatably mounted on one end of the wheel rod. The other end of the wheel rod is mounted on the mounting frame by bolts. Mounting shafts are provided below the front and rear ends of the mounting frame. The pair of mounting shafts are respectively configured as a rotating shaft and a fixed shaft. A transmission motor is provided at one end of the rotating shaft, and an end support wheel is provided on the mounting shaft corresponding to the lower support wheel. A belt is provided between the lower support wheel, the upper support wheel, and the end support wheel.

[0012] Furthermore, the structure of the mounting frame includes a pair of mounting plates, a support rod, and a pair of mounting rods. The pair of mounting plates are respectively mounted on the frame of the cutting mechanism and the support of the sewing worktable. The support rod is located between the upper middle parts of the pair of mounting plates. The pair of mounting rods are respectively located between the lower two sides of the pair of mounting plates. The lower support wheel and the upper support wheel are mounted on the mounting rods.

[0013] Furthermore, the front end of the sewing workbench is provided with an anti-tilting mechanism. The anti-tilting mechanism includes a rotating shaft rotatably mounted on the sewing workbench, a pair of rollers on the front side of the rotating shaft, the rollers being connected to the rotating shaft as a whole through a connector, and a rotary cylinder at one end of the rotating shaft. The rotary cylinder drives the rollers to rotate up and down through the rotating shaft.

[0014] Working principle: The rolled raw material is placed on the placement mechanism. The front end of the raw material passes under the lower shaft of the placement mechanism and then passes between the upper and lower pressure rollers of the tension control mechanism. It then passes sequentially through the lower support roller at the front end of the movable support roller assembly, the upper support roller at the front end of the support frame, the lower support roller in the middle of the support roller assembly, the upper support roller in the middle of the support frame, the lower support roller at the rear end of the support roller assembly, and the upper support roller at the rear end of the support frame. It then passes between the support plate and pressure plate of the anti-deviation mechanism and enters the cutting mechanism. In use, the distance between the pair of baffles of the anti-deviation mechanism is adjusted according to the actual situation. The motor of the traction assembly is started. The motor drives the traction wheel to rotate through the shaft. The traction wheel moves the raw material towards the cutting mechanism through friction. As the raw material is gradually released, the placement frame moves accordingly according to the direction of the force on the raw material. Combined with the tension control mechanism and the anti-deviation mechanism, the raw material is prevented from deviating, ensuring flatness during the raw material conveying process.

[0015] When the raw material reaches the cutting position, the clamping cylinder is activated. The clamping cylinder, via a connecting rod, moves the pressure rod downwards to clamp the raw material. Simultaneously, the lifting cylinder is activated. The lifting cylinder, via a lifting plate, moves the cutter downwards to cut the raw material. The clamping cylinder, via a connecting rod, moves the pressure rod back to its original position. The lifting cylinder, via a lifting plate, moves the cutter back to its original position. The lifting cylinder of the transfer mechanism moves the rear end of the connecting arm upwards, bringing a pair of push rods into contact with the cut raw material. Simultaneously, the translation cylinder is activated, moving the moving table towards the sewing worktable, pushing the cut raw material onto the sewing worktable. When the cut raw material approaches the anti-tilting mechanism, the anti-tilting mechanism's rotating cylinder rotates the shaft counterclockwise, lifting a pair of rollers upwards. Then, the anti-tilting mechanism's rotating cylinder returns the shaft to its original position. The downward conveying mechanism uses friction to move the cut raw material behind the sewing worktable. The anti-tilting mechanism and the downward conveying mechanism ensure that the cut raw material is transported smoothly. The sewing machine sews the cut raw material together, and the operator collects the sewn material.

[0016] The beneficial effects of this utility model are as follows: This utility model can automatically feed materials, freeing up manual feeding, and can work continuously, saving time and labor. The placement mechanism moves according to the force on the raw material, and the tension control mechanism and anti-deviation mechanism prevent the raw material from shifting, ensuring the flatness of the raw material during the cutting and conveying process. By adjusting the spacing of a pair of baffles in the anti-deviation mechanism, it can be adapted to woven bags of different widths. The transfer mechanism, anti-tilting mechanism, and downward conveying mechanism can prevent the raw material from shifting after cutting, facilitating subsequent sewing work. The parts not described in detail in this utility model are existing commonly used technologies. Attached Figure Description
