Description

Technical Field

[0001] The utility model relates to a device for producing warp-weft composite cylindrical woven bags, belonging to the technical field of woven bag production. Background Art

[0002] Plastic woven bags, also known as snakeskin bags, are a type of plastic. They are typically made from various chemical plastics, such as polyethylene and polypropylene. These are processed into flat strands and then woven on a circular loom. Existing circular looms use a specified number of plastic flat strands, depending on the fabric width and the flat strand width. The warp yarns are then cross-woven by a warp frame. The weft shuttle moves in a circular motion through the cross-woven strands, weaving the fabric into a tube. The tube is then heat-melted to a fixed length and cut to complete the production of the plastic woven bag.

[0003] Patent No. 202222916089.9 discloses a circular loom for processing plastic woven bags, belonging to the technical field of circular looms. The utility model comprises a base plate, a circular loom body, a bracket, and a material transfer roller. A mounting plate is fixedly mounted on the base plate, a mounting box is fixedly mounted on the mounting plate, a movable block is slidably mounted on the mounting box, a mounting slot is defined within the movable block, a plug plate is slidably mounted on the mounting slot, a damper is provided in the mounting slot, a socket is defined on the bracket, and a drive member for driving the plug plate to move horizontally is provided within the mounting box. This circular loom for processing plastic woven bags can improve the stability of the bracket.

[0004] The current technology is not comprehensive and has the following disadvantages: the traditional woven bags are made by cross-weaving the warp and weft threads on a circular loom, which results in a complicated structure of the circular loom in the prior art and low efficiency in weaving woven bags.

[0005] In order to solve one of the above problems, a warp and weft composite cylindrical woven bag production equipment is urgently needed. Utility Model Content

[0006] Based on the above deficiencies in the existing technology, the technical problem to be solved by the present invention is: how to realize the warp and weft composite by utilizing the adhesiveness of hot melt adhesive in a molten state, without the need for traditional cross-weaving, and to provide a warp and weft composite cylindrical woven bag production equipment for this purpose.

[0007] The warp and weft composite cylindrical woven bag production equipment described in the present invention includes a core mold and a turntable arranged to rotate around the core mold, and is characterized in that: a traction and lifting roller is arranged above the core mold, a warp guide frame is arranged at the bottom of the core mold, warp supply mechanisms are arranged on both sides of the turntable, a weft supply mechanism and a pressure roller are installed on the turntable, and a gluing mechanism for applying hot melt glue to the weft is installed on the weft supply mechanism.

[0008] The warp and weft threads are composited by utilizing the adhesiveness of hot melt adhesive in a molten state, eliminating the need for traditional cross-weaving. The warp supply mechanism supplies the warp threads to the core mold. The warp threads on the warp supply mechanism are redirected by the warp guide frame and then run upward along the outer wall of the core mold. At the same time, the turntable rotates with the gluing mechanism, the weft supply mechanism, and the pressure roller. The weft supply mechanism supplies the weft threads to the core mold. When the weft threads run to the working area of ​​the gluing mechanism, the gluing mechanism is used to apply glue to the weft threads. The glued weft threads are bonded to the warp threads on the outside of the core mold. The pressure roller and the core mold form a counter-roller compaction effect. The glue also blocks the gap between the warp threads and the weft threads, forming a composite cylindrical woven bag. The bag is then pulled to the cloth winding machine via the lifting roller.

[0009] Preferably, the warp supply mechanism includes a bobbin mounting frame, the bobbin mounting frame is connected to a warp wire frame, and the warp on the bobbin mounting frame enters the warp guide frame from the warp wire frame.

[0010] Preferably, the glue coating mechanism includes a glue coating roller and a glue supply mechanism for providing hot melt glue to the glue coating roller.

[0011] Preferably, the weft supply mechanism comprises a weft mounting frame mounted on a turntable and a weft guide frame mounted on the turntable. As the turntable rotates, the weft supply mechanism rotates, causing the weft on the mounting frame to be wound around the outer wall of the core mold via the guide frame. Simultaneously, the speed of the traction and lifting mechanism is determined by the speed at which the weft is wound around the core mold, achieving synchronous operation and ensuring that the weft is wound around the core mold uniformly.

[0012] Preferably, the turntable is rotatably mounted on a turntable frame and driven by a motor, and the turntable frame is supported on the ground by legs or mounted on a lower bracket of the core mold.

[0013] Preferably, the core mold is a hollow cylindrical structure with a circular cross-section, and a cooling device can be added inside the core mold as needed.

[0014] At least one group of gluing mechanisms is provided, and at least one group of pressing rollers is provided.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The warp and weft composite cylindrical woven bag production equipment described in the present invention utilizes the adhesiveness of the coating glue in a molten state to composite the warp and weft threads. It does not require traditional cross-weaving, thus reducing the traditional cams, transmission guide rods, shuttle pushers, traditional shuttles, buckles, hemp hemp belts and other vulnerable rollers, shuttle wheels and brackets. It improves production efficiency and capacity, and makes product specifications standard. Because there are no factors such as shuttle wheel pressure and push wheel friction, the rate of broken warp and missing weft defective products is reduced. The woven bags produced do not have seams or detached threads, and the subsequent printing and coating are more beautiful, which increases the flatness of the bags. Subsequent products do not need to be coated again, which reduces the production process, reduces the complexity of the equipment, and enhances the stability and flexibility of the composite cylindrical woven bag production equipment. It is easy for operators to learn and understand, and each person can add multiple machines to operate, reducing wages and greatly improving production capacity.

[0017] The warp and weft composite cylindrical woven bag production equipment of the utility model produces composite cylindrical woven bags that are airtight, moisturizing, moisture-proof, waterproof, and have better flatness, and are convenient for subsequent color printing and coating.

[0018] The warp and weft composite cylindrical woven bag production equipment of the utility model can produce composite cylindrical woven bags with no loose threads or burrs at the bag opening after cutting.

[0019] The composite cylindrical woven bag production equipment for warp and weft composite woven bags of the utility model is less likely to have its bottom opened after the bottom is sewn. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Example 1, as Figure 1-2 As shown, the warp and weft composite cylindrical woven bag production equipment includes a core mold 2 and a turntable 1 arranged to rotate around the core mold 2, a traction and lifting roller 5 is arranged above the core mold 2, a warp guide frame 4 is arranged at the bottom of the core mold 2, a warp supply mechanism 3 is arranged on both sides of the turntable 1, a weft supply mechanism 7 and a pressure roller 11 are installed on the turntable 1, and a gluing mechanism 6 for applying hot melt adhesive (glue) to the weft is installed on the weft supply mechanism 7.

[0026] The warp guide frame 4 is annular.

[0027] The core mold 2 is a mold for changing the width of the woven bag, commonly known as a size ring or specification ring. The core mold 2 can also determine whether water cooling or air cooling is required inside the core mold 2 according to the glue coating temperature and glue coating thickness to ensure the bonding effect.

[0028] The warp and weft threads are compounded by the adhesiveness of hot melt adhesive in a molten state, without the need for traditional cross-weaving. The warp supply mechanism 3 provides the warp threads for the core mold 2. The warp threads on the warp supply mechanism 3 are changed in direction by the warp guide frame 4 and run upward along the outer wall of the core mold 2. At the same time, the turntable 1 rotates with the gluing mechanism 6, the weft supply mechanism 7, and the pressure roller 11. The weft supply mechanism 7 provides the weft threads for the core mold 2. When the weft threads run to the working area of ​​the gluing mechanism 6, the gluing mechanism 6 is used to gluing the weft threads. The glued weft threads are bonded to the warp threads on the outside of the core mold 2. The pressure roller 11 and the core mold 2 form a roller compaction effect. The glue also blocks the gap between the warp threads and the weft threads, forming a composite cylindrical woven bag 10, and is pulled to the cloth winding machine by the lifting roller 5.

[0029] Example 2, as Figure 1-2 As shown, the warp and weft composite cylindrical woven bag production equipment includes a core mold 2 and a turntable 1 arranged to rotate around the core mold 2, a traction and lifting roller 5 is arranged above the core mold 2, a warp guide frame 4 is arranged at the bottom of the core mold 2, a warp supply mechanism 3 is arranged on both sides of the turntable 1, a weft supply mechanism 7 and a pressure roller 11 are installed on the turntable 1, and a gluing mechanism 6 for applying hot melt adhesive (glue) to the weft is installed on the weft supply mechanism 7.

[0030] At least one group of the gluing mechanisms 6 is provided, and at least one group of the pressing rollers 11 is provided.

[0031] Furthermore, the warp supply mechanism 3 includes a bobbin mounting frame 3.1, the bobbin mounting frame 3.1 is connected to a warp wire frame 3.2, and the warp on the bobbin mounting frame 3.1 enters the warp guide frame 4 from the warp wire frame 3.2.

[0032] Furthermore, the gluing mechanism 6 includes a gluing roller and a gluing mechanism 9 for providing hot melt glue to the gluing roller.

[0033] Furthermore, the weft supply mechanism 7 includes a weft mounting frame mounted on the turntable 1 and a weft guide frame 7.2 mounted on the turntable 1. As the turntable 1 rotates, the weft supply mechanism 7 rotates, causing the weft on the mounting frame 7.1 to be wound around the outer wall of the core mold 2 via the guide frame 7.2. Simultaneously, the lifting speed of the traction and lifting is determined by the speed at which the weft is wound around the core mold 2, achieving synchronous operation and ensuring that the wefts are wound around the core mold 2 in a consistent manner.

[0034] Furthermore, the turntable 1 is rotatably mounted on a turntable frame and driven by a motor 8, and the turntable frame is supported on the ground by legs or mounted on a lower bracket of the core mold 2. This is an existing structure.

[0035] Furthermore, the core mold 2 is a hollow cylindrical structure with a circular cross-section, and a cooling device can be added inside the core mold 2 as needed.

[0036] The warp and weft composite cylindrical woven bag production equipment described in the utility model utilizes the adhesiveness of the coating glue in a molten state to composite the warp and weft threads. This eliminates the need for traditional cross-weaving and reduces the number of vulnerable rollers, shuttle wheels, and brackets, such as traditional cams, transmission guide rods, shuttle pushers, traditional shuttles, buckles, and hemp belts. This improves production efficiency and capacity, standardizes product specifications, and reduces weft defects and defective products. Because there is no shuttle wheel pressure or push wheel friction, the woven bags produced are seamless and do not shed threads, allowing for better processing of subsequent printing and coating, increasing the flatness of the bags. Subsequent products do not require further coating, reducing production steps, lowering equipment complexity, and enhancing the stability and flexibility of the composite cylindrical woven bag production equipment. Operators are easy to learn and understand, and each person can operate multiple machines, reducing wages and significantly increasing production capacity.
