[0002] Plastic woven bags are made of PP material, which is a product made of polypropylene through drawing, weaving, sewing and color printing. Most of the existing woven bag production equipment uses circular looms for weaving, and the uncut woven bags are rolled up after weaving for subsequent transportation or processing. The current circular looms will produce a large vibration during work, but most circular looms are not equipped with shock absorbing mechanisms, resulting in excessive vibrations that can easily cause the circular loom to hook the line inaccurately during weaving, thereby increasing the defective rate of the product and reducing the production quality of plastic woven bags.

[0003] For example, the existing Chinese publication number is: CN211311741U, a circular loom for plastic woven bags, which: "comprises a weaving frame, a circular loom body is fixedly mounted on the inner wall of the bottom side of the weaving frame, a first rotating hole is opened on the top of the weaving frame, the same weaving transmission roller is rotatably mounted on the inner walls on both sides of the first rotating hole, and a cloth collecting rack is placed on one side of the weaving frame."

DETAILED DESCRIPTION

[0023] In the following description, a large number of specific details are given to provide a more thorough understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the utility model, some technical features known in the art are not described.

[0024] Unless otherwise defined, the directions of up, down, left, right, front, back, inside and outside involved in this document are based on the directions of up, down, left, right, front, back, inside and outside in the figures shown in the present utility model, and are explained here together.

[0025] The connection method can be bonding, welding, bolt connection, etc., depending on actual needs.

[0026] like Figures 1 to 4 The plastic woven bag circular loom shown includes a base 1, the inner cavity of the base 1 is U-shaped, the top surface of the base 1 is provided with a top plate 2, the size of the top plate 2 is smaller than the size of the inner cavity of the base 1, and the top plate 2 is arranged in the U-shaped inner cavity of the top surface of the base 1.

[0027] A plurality of fixed blocks 4 are fixedly installed on the bottom surface of the top plate 2, and the distance between each fixed block 4 is equidistant. A buffer spring 5 is fixedly connected to the bottom surface of each fixed block 4, and the free end of each buffer spring 5 is fixed to the bottom surface of the inner cavity of the base 1. When vibration is generated by processing the braided wire, the vibration will be transmitted to the fixed block 4 through the top plate 2, so that the fixed block 4 can exert downward pressure, that is, the fixed block 4 can squeeze the buffer spring 5, and the buffer spring 5 is squeezed and deformed, so that the deformed buffer spring 5 can buffer the downward pressure of the fixed block 4, thereby achieving a damping effect, so as to achieve the purpose of vibration reduction.

[0028] The two sides of each fixed block 4 are hinged with an articulated rod 6, and the free end of each articulated rod 6 is hinged with a movable block 7. The bottom surface of the inner cavity of the base 1 and below each fixed block 4 are symmetrically fixed with a fixed plate 8, and a damping spring 9 is provided between each fixed plate 8 and each movable block 7. When the fixed block 4 applies downward pressure, the fixed block 4 will synchronously drive the two articulated rods 6 to the lower end, and then the two articulated rods 6 will push the movable block 7 to move respectively, so that the movable block 7 can cooperate with the fixed plate 8 to squeeze the damping spring 9, and the damping spring 9 can also be deformed by squeezing, so that the deformed damping spring 9 can buffer the squeezing of the two articulated rods 6 and the two movable blocks 7 to achieve the damping effect, so as to achieve the purpose of vibration reduction, and the damping spring 9 and the buffer spring 5 can cooperate to double buffer the downward pressure of the top plate 2 and the fixed block 4, so as to achieve the effect of vibration reduction, reduce the problem of inaccurate hooking during weaving due to excessive vibration, and improve the quality of plastic woven bag production.

[0029] Every two hinged rods 6 are inclined in opposite directions, thereby ensuring that the two hinged rods 6 can move in opposite directions, thereby ensuring that the damping spring 9 can be squeezed by the movable block 7 and the fixed plate 8 .

[0030] A weaving frame 3 is installed on the top surface of the top plate 2. Four vertical rods 10 are installed on the top surface of the top plate 2 and on one side of the weaving frame 3. Each vertical rod 10 is longitudinally installed on the top surface of the top plate 2. A plurality of connecting plates 11 are fixed between every two vertical rods 10. The distances between the plurality of connecting plates 11 are equidistantly arranged. A plurality of transfer rollers 12 for winding the weaving wire are equidistantly arranged on the opposite side of each connecting plate 11. The transfer rollers 12 can also be connected to the connecting plates 11. When processing the weaving wire, the weaving wire can be first wound around the transfer roller 12, and one end of the weaving wire can be passed through the weaving frame 3 for processing.

[0031] The top surface of the weaving frame 3 and a side surface facing the four vertical rods 10 are respectively provided with a feeding port 13 and a transfer port 14 for conveying woven fabrics. The weaving wire can first enter the weaving frame 3 from the transfer port 14 for processing, and then be discharged from the feeding port 13 after the processing is completed. The inner walls on both sides of the feeding port 13 and the bottom surface of the inner cavity of the weaving frame 3 are respectively provided with a transmission roller 15 and a feeding roller 17 for conveying woven fabrics and weaving wires. The bottom surface of the inner cavity of the weaving frame 3 is provided with a weaving device 16 for processing the weaving wire. After the weaving wire enters the weaving frame 3 through the transfer port 14, the weaving wire is passed from the bottom of the transmission roller 15 and then connected to the weaving device 16. After the processing is completed, one end of the woven fabric is brought to the feeding port 13 and passed from the top of the feeding roller 17 for winding and collection. The weaving device 16 is set to an existing structure, and it only needs to be able to process the weaving wire into woven fabric, and the structures related to the processing of the weaving wire into woven fabric can be set to an existing structure to ensure that the weaving wire can be processed into woven fabric so that it can be processed into a plastic woven bag later.

[0032] Working principle:

[0033] The plastic woven bag circular loom winds the woven wire on the feed roller 12, and allows the woven wire to pass through the feed port 14 and the transmission roller 15 into the weaving device 16 for processing. The processed woven fabric will be transported outward from the feed port 13 and the feed roller 17. When vibration is generated during processing, the vibration will be transmitted to multiple fixed blocks 4 through the top plate 2, and the vibration will exert downward pressure on the top plate 2 and the fixed blocks 4, so that the fixed blocks 4 can squeeze the buffer springs 5, and the buffer springs 5 ​​will be deformed after being squeezed, thereby buffering the downward pressure of the fixed blocks 4. The damping effect is achieved. At the same time, when the fixed block 4 is pressed down, the two hinged rods 6 are driven to be pressed down synchronously. When the two hinged rods 6 are pressed down, the movable block 7 is pushed to squeeze the damping spring 9. The damping spring 9 is also deformed after being squeezed, thereby buffering the downward pressure of the fixed block 4. The purpose of damping is also achieved to achieve the effect of vibration reduction. The buffer spring 5 and the damping spring 9 cooperate with each other to reduce the vibration transmitted by the top plate 2, reduce the problem of inaccurate hooking during weaving due to excessive vibration, and improve the quality of plastic woven bag production.
