Description

Technical Field

[0001] This utility model relates to the technical field of woven bag production equipment, specifically a woven bag edge processing device. Background Technology

[0002] During the production process of woven bags, both sides of the woven bag need to be sealed. In order to ensure the strength of the woven bag, the edges of the sealed woven bag must be aligned and there should be no wrinkles.

[0003] The prior art includes a sealing device for weaving production, disclosed in CN217438416U. This device includes a mounting frame with vertical plates symmetrically fixedly mounted on its surface. An operating plate is fixedly mounted on the top of each vertical plate. Sliding blocks are symmetrically fixedly mounted on the surface of the operating plate, and sliding toothed blocks are movably mounted on each sliding toothed block. The operating plate has two movable slots located between the sliding toothed blocks, each slot being close to one side of a sliding toothed block. A connecting block is fixedly mounted at one end of each sliding toothed block, and a movable rod is fixedly mounted at the bottom of each connecting block. The movable rod is movably mounted to the movable slot, and by moving the movable rod, the sealing device on the movable rod performs double-sided sealing on the woven bag.

[0004] When the above-mentioned equipment seals the edges of woven bags, residual air inside the bags can cause misalignment of the bag edges, compromising the bag's strength. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the aforementioned problems in the prior art, this utility model provides an edge treatment device for woven bags, which can remove air from the sealed woven bags and ensure the quality of the sealing.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, the main technical solutions adopted by this utility model include:

[0009] An edge-treatment device for woven bags includes a housing. A conveyor belt is installed inside the housing cavity. Pressure rollers are symmetrically and rotatably mounted on both sides above the conveyor belt. A scraper is positioned between the pressure rollers, and the height of the scraper is adjustable. A traction guide roller is positioned on the upper left side of the housing cavity. An edge-sealing mechanism is fixedly installed on the inner wall of the housing between the traction guide roller and the conveyor belt. This device can remove air from the woven bags to be sealed, ensuring the quality of the edge sealing.

[0010] Preferably, the front and back of the outer casing are provided with oblong holes, and the scraper is fixed to the outer casing by bolts and oblong holes.

[0011] Preferably, a feeding trough is provided at an angle on the left side of the outer casing.

[0012] Preferably, the scraper is a hollow structure with an opening at one end on the right side, and the scraper is also connected to a dust extraction mechanism via an air pipe.

[0013] (III) Beneficial Effects

[0014] This utility model provides an edge treatment device for woven bags. It has the following beneficial effects:

[0015] (1) The pressure roller can flatten the woven bag and expel the air inside the woven bag during the conveying process, thus ensuring the sealing quality. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figure 1-2 As shown, the woven bag edge processing equipment of this embodiment includes a housing 1, a conveyor belt 2 installed inside the housing 1, and pressure rollers 3 symmetrically and rotatably mounted on the left and right sides above the conveyor belt 2. The pressure rollers 3 can flatten the woven bag. A scraper 4 is arranged between the pressure rollers 3, which can remove air from the woven bag. The height of the scraper 4 is adjustable to suit the sealing of woven bags of different thicknesses. A traction guide roller 5 is arranged on the upper left side of the inner cavity of the housing 1, and a sealing mechanism 6 is fixedly arranged on the inner wall of the housing 1 between the traction guide roller 5 and the conveyor belt 2.

[0021] Furthermore, the front and back of the outer casing 1 are longitudinally provided with oblong holes 7, and the scraper 4 is fixed to the outer casing 1 by bolts and oblong holes 7. The fixed height of the scraper 4 can be adjusted.

[0022] Furthermore, a feeding trough 8 is inclinedly provided on the left side of the outer casing 1.

[0023] Furthermore, the scraper 4 is a hollow structure with an opening at one end on the right side, and the scraper 4 is also connected to a dust extraction mechanism via an air pipe. This allows it to collect the dust generated during the extrusion and exhaust process.

[0024] Working principle: The height of scraper 4 is adjusted according to the thickness of the woven bag. During adjustment, scraper 4 can be fixed at a suitable height position in the waist-shaped hole 7 using bolts. The woven bag is conveyed by conveyor belt 2, pressure roller 3 flattens the woven bag, and scraper 4 squeezes out the air inside the woven bag. After being flattened and the air squeezed out, the woven bag is sealed by sealing mechanism 6, and then pulled by traction guide roller 5 and discharged through the discharge chute 8. The exhaust dust removal mechanism can extract the dust generated during the exhaust process by scraper 4 through a hose.
