Technical Field

[0001] This utility model relates to a circular loom, specifically a circular loom for bonding inner lining film to plastic woven bags, belonging to the field of plastic woven bag processing technology. Background Technology

[0002] A circular loom is a machine used for weaving tube fabric. The warp frame of a circular loom has many spindles, and a specified number of warp yarns are used depending on the width of the fabric and the width of the flat yarn. Before entering the circular loom, the warp yarns are crossed by the hem frame, and the weft shuttle moves in a circular motion through these openings to pass through the warp yarns, weaving the fabric into tubes. The number of weft yarns woven into a circular loom corresponds to the number of shuttles it has. For plain weave fabrics, plain looms, rapier looms, and water-jet looms can be used. A circular loom for producing plastic woven bags is a type of circular loom used for this purpose.

[0003] Chinese Patent Publication No. CN208649591U discloses an environmentally friendly and energy-saving circular loom, including a circular loom base. A circular loom body is fixed at the center of the upper surface of the circular loom base. A support frame is welded around the outer perimeter of the circular loom body on the upper surface of the circular loom base. A first conveying roller is rotatably connected to the top of the support frame via a rotating shaft. An L-shaped fixing frame is welded to one side wall of the support frame. A second conveying roller is rotatably connected to the L-shaped fixing frame via a rotating shaft.

[0004] However, the inventor of the above-mentioned device believes that there are certain defects. During the winding process of the woven bag, the woven bag passes through multiple conveying rollers. The lack of a limiting mechanism makes the woven bag prone to deviation during the winding process, which affects the winding effect of the woven bag. Therefore, this utility model provides a circular loom for plastic woven bags with inner lining film bonding. Utility Model Content

[0005] The purpose of this invention is to provide a circular loom for bonding plastic woven bags with inner lining film in order to solve the above-mentioned problems. This addresses the issue in the prior art where the lack of a limiting mechanism causes the woven bag to easily deviate during the winding process, affecting the winding effect of the woven bag.

[0006] This utility model is achieved through the following technical solution: a circular loom for bonding inner lining film to plastic woven bags, including a fixed base, a circular loom body and a fixed bracket are fixedly connected to the top of the fixed base, a fixed through box is embedded in the top of the fixed bracket, a guide roller is rotatably connected inside the fixed through box, two limiting blocks are slidably connected on the guide roller, an adjustment mechanism for adjusting the distance between the two limiting blocks is provided on the fixed through box, the adjustment mechanism includes a connecting plate fixed to one side of the two limiting blocks, a connecting slide rod is fixedly connected to one side of the connecting plate, the connecting slide rod is slidably connected to one end of the fixed through box, two fixed seats are fixedly connected to the top of the fixed bracket, and a take-up roller is rotatably connected between the two fixed seats.

[0007] Preferably, the adjustment mechanism further includes a movable plate fixed to one end of the connecting slide rod. A first spring is sleeved on the connecting slide rod. The first spring is located between one side of the connecting plate and the inner wall of the fixed box. Under the action of the spring force of the first spring, when the connecting plate is not under force, it pushes the limiting block to slide closer to the middle of the guide roller.

[0008] Preferably, a fixed slide rod is fixedly connected to the fixed box, and an adjusting rod is slidably connected to the fixed slide rod. Both ends of the adjusting rod are hinged to pressing rods, and the other ends of the two pressing rods are respectively hinged to two movable plates. By driving the adjusting rod to slide on the fixed slide rod, the pressing rods press the two movable plates away from each other.

[0009] Preferably, an adjusting screw is rotatably connected to the fixed box, and an adjusting rod is threaded onto the adjusting screw. A first motor that drives the adjusting screw to rotate is fixedly connected to the fixed bracket. By starting the first motor, the adjusting screw is driven to rotate, causing the adjusting rod to slide on the fixed slide bar.

[0010] Preferably, a second motor for driving the take-up roller to rotate is fixedly connected to the fixed base, and a smoothing mechanism is provided between the two fixed bases. The take-up roller is driven to rotate between the two fixed bases by starting the second motor.

[0011] Preferably, the smoothing mechanism includes a sliding rod that slides between two fixed seats, and a smoothing rod is fixedly connected to the bottom of the sliding rod. The smoothing rod is used to smooth the woven bag wound on the take-up roller.

[0012] Preferably, each of the two fixed seats has a side sliding groove on one side that is close to each other. The two ends of the sliding rod are slidably connected to the inside of the two side sliding grooves respectively. The top of each end of the sliding rod is fixedly connected to a second spring. The second spring is located inside the side sliding groove. Under the action of the second spring force, the smoothing rod abuts against the outer surface of the take-up roller.

[0013] This utility model provides a circular knitting machine for bonding inner lining film to plastic woven bags, which has the following beneficial effects:

[0014] 1. This device reduces the number of guide rollers for woven bags during transport by mounting the take-up roller on a fixed bracket. Two limiting blocks on the guide roller limit the two sides of the woven bag to prevent it from shifting during transport and affecting the winding effect of the take-up roller. The distance between the two limiting blocks can be adjusted by the adjustment mechanism to limit woven bags of different sizes, making it highly adaptable.

[0015] 2. The device drives the adjusting screw to rotate by starting the first motor, which in turn pushes the adjusting rod to slide on the fixed slide rod. Two pressing rods push the two movable plates away from each other. The connection between the connecting plate and the connecting slide rod causes the two limiting blocks to move away from each other. When the movable plate is not under force, the rebound of the first spring causes the two limiting blocks to press and move closer together, thereby quickly adjusting the distance between the two limiting blocks.

[0016] 3. The device uses a smoothing rod, which, under the action of a second spring, smooths the woven bag wound on the outer surface of the take-up roller, thereby improving the winding effect of the take-up roller. Attached Figure Description
