Description

Technical Field

[0001] This utility model belongs to the technical field of non-woven bag production equipment, and in particular relates to an automatic bundling device for non-woven bags. Background Technology

[0002] Non-woven bags, as a new generation of environmentally friendly materials, are widely used in shopping, packaging, and industrial protection due to their advantages such as moisture resistance, breathability, recyclability, and biodegradability. With the advancement of environmental policies and the expansion of market demand, the production scale of non-woven bags continues to grow. The efficiency and quality of the post-production bundling process have become key factors affecting enterprise capacity release and product delivery quality.

[0003] In the existing technology, a pressing structure is used to apply pressure to the central area of ​​stacked non-woven bags, and then the bags are tied from both sides of the central area using bundling ropes. In this method, the sides of the stacked non-woven bags lack effective restraint, and the edges are prone to warping due to uneven force. This causes the bundling ropes to loosen easily after tying, requiring manual adjustment. This not only reduces bundling efficiency but also affects the neatness of the products. Utility Model Content

[0004] The purpose of this invention is to provide an automatic bundling device for non-woven bags, which solves the problem in traditional technology where stacked non-woven bags lack effective restraint on both sides, are prone to edge warping due to uneven force, and the bundling rope is easy to loosen after binding, requiring manual secondary adjustment, which not only reduces bundling efficiency but also affects the neatness of the product.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An automatic bundling device for non-woven bags includes: A workbench, the top of which is fixedly connected to a placement frame, and two bundling ropes are placed inside the placement frame; The extrusion mechanism includes a mounting frame fixedly connected to a workbench. An extrusion plate is vertically connected to the mounting frame. The extrusion plate includes a center plate and side plates located on both sides of the center plate. The side of the center plate and the side plate on the same side form a bundling channel, and multiple separable connecting components are connected between them. In the initial state, the connecting end of the connecting component crosses the bundling channel and connects the center plate and the side plate. In the working state, it is disconnected from the bundling channel. The two bundling channels are located above the two bundling ropes in a one-to-one correspondence.

[0006] Preferably, two rope grooves are provided at both ends of the placement frame, and the bundling rope is placed inside the two rope grooves on the same side.

[0007] Preferably, an electric telescopic rod is installed on the top of the mounting frame, and the output end of the electric telescopic rod is fixedly connected to the top of the center plate.

[0008] Preferably, multiple mounting slots are provided on both sides of the center plate, and multiple rotating slots are provided on the side of the two side plates near the center plate. The multiple rotating slots correspond one-to-one with the multiple mounting slots. The connecting assembly includes a connecting block rotatably connected inside the rotating slot and an electromagnet installed inside the corresponding mounting slot. A torsion spring is installed between the connecting block and the inner wall of the rotating slot. A permanent magnet is installed at the end of the connecting block away from its rotating end. The electromagnet and the permanent magnet are magnetically engaged. In the initial state, the electromagnet and the permanent magnet are magnetically attracted, and in the working state, they are magnetically repelled.

[0009] Preferably, the connecting block is fan-shaped, and in its initial state, its arc edge spans the bundling channel.

[0010] Preferably, a plurality of limiting rods are fixedly connected to the top of the center plate, and the top ends of the limiting rods are slidably connected to the mounting frame.

[0011] Compared with the prior art, the present invention has the following beneficial effects: This invention utilizes a compression plate structure composed of a central plate, two side plates, and multiple separable connecting components to achieve full-range constraint on the bundling position. In the initial state, the connecting components span the bundling channel, connecting the central plate and the side plates. The compression plate is an integrated structure. When driven by the electric telescopic rod, it can simultaneously compress the center and both sides of the non-woven bag, preventing warping of the sides due to lack of constraint. During bundling, the connecting components disengage one by one from the bundling channel, while the remaining connecting components maintain the connection between the central plate and the side plates, ensuring that the non-woven bag remains flat during bundling. This effectively solves the problem of loosening after bundling and significantly improves the uniformity of the bundled product. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Reference Figures 1-3 An automatic bundling device for non-woven bags includes: Workbench 1, with a placement frame 2 fixedly connected to the top of workbench 1, and two bundling ropes 4 placed inside the placement frame 2.

[0016] Two rope grooves 3 are provided at both ends of the placement frame 2, and the bundling rope 4 is placed inside the two rope grooves 3 on the same side.

[0017] The inside of the placement frame 2 is used to store stacked non-woven bags, and the binding rope 4 is located below the stacked non-woven bags.

[0018] The extrusion mechanism includes a mounting frame 5 fixedly connected to the workbench 1. An extrusion plate 7 is vertically connected to the mounting frame 5. The extrusion plate 7 includes a center plate 8 and side plates 9 located on both sides of the center plate 8. The side of the center plate 8 and the side plates 9 on the same side form a bundling channel 15, and multiple separable connecting components are connected between them. In the initial state, the connecting end of the connecting component crosses the bundling channel 15 and connects the center plate 8 and the side plates 9. In the working state, it is separated from the bundling channel 15. The two bundling channels 15 are located above the two bundling ropes 4 in a one-to-one correspondence.

[0019] The center plate 8 and the side plate 9 are connected by multiple separable connecting components. When the extrusion plate 7 extrudes the stacked non-woven bags, the multiple connecting components separate and close one by one, so that the bundling channel 15 is briefly connected in time. This makes it easier for the bundling rope 4 to cross the bundling channel 15 to bundle the stacked non-woven bags. Compared with only extruding the center of the stacked non-woven bags, this effectively avoids the warping of the sides of the stacked non-woven bags from affecting the bundling operation. The operator does not need to work hard to press down the warped sides again to bundle, which improves the bundling efficiency and bundling quality.

[0020] The top of the mounting bracket 5 is equipped with an electric telescopic rod 6, and the output end of the electric telescopic rod 6 is fixedly connected to the top of the center plate 8.

[0021] When the electric telescopic rod 6 is working, its output end drives the central plate 8 and the two side plates 9 to move downward, which fully compresses the non-woven bags stacked in the placement frame 2.

[0022] Multiple mounting slots 13 are provided on both sides of the center plate 8, and multiple rotating slots 10 are provided on the side of the two side plates 9 near the center plate 8. The multiple rotating slots 10 correspond one-to-one with the multiple mounting slots 13. The connecting component includes a connecting block 11 rotatably connected inside the rotating slot 10 and an electromagnet 14 installed inside the corresponding mounting slot 13. A torsion spring is installed between the connecting block 11 and the inner wall of the rotating slot 10. A permanent magnet 12 is installed at the end of the connecting block 11 away from its rotating end. The electromagnet 14 and the permanent magnet 12 are magnetically engaged. In the initial state, the electromagnet 14 magnetically attracts the permanent magnet 12, and in the working state, the two magnetically repel each other.

[0023] Under the elastic force of the torsion spring, the connecting block 11 maintains a stable angle, thereby maintaining the stability of the bundling channel 15.

[0024] In the initial state, the connecting block 11 spans the bundling channel 15, and the electromagnet 14 magnetically attracts the permanent magnet 12, forming a fixed connection effect. With the connection of multiple connecting components, the center plate 8 and the side plate 9 maintain a stable connection state. Thus, when the center plate 8 moves down, the two side plates 9 move down synchronously, forming a squeezing effect on both sides of the bundling position, avoiding the impact of warping on bundling.

[0025] In operation, the operator manipulates the bundling rope 4 to pass through the bundling channel 15. The bundling rope 4 overcomes the elastic force of the torsion spring and the magnetic attraction of the electromagnet 14 to the permanent magnet 12, thereby pushing the connecting blocks 11 apart one by one. The remaining connecting blocks 11 remain connected to the center plate 8 and the side plate 9 until one end of the bundling rope 4 is pulled up and moves from the top to the bottom of the bundling channel 15. Together with the other end of the bundling rope 4, the stacked non-woven bags are bundled. At the same time, multiple electromagnets 14 can be controlled by an external controller to change and restore their magnetic poles in sequence, thereby causing multiple connecting blocks 11 to disengage from the bundling channel 15 and return to their initial state in sequence. This effectively avoids direct contact between the bundling rope 4 and the connecting blocks 11, preventing wear between them.

[0026] The connecting block 11 is fan-shaped, and its arc edge spans the bundling channel 15 in the initial state, which effectively prevents the connecting block 11 from hooking the passing bundling rope 4 when it rotates and retracts into the rotating groove 10.

[0027] Multiple limiting rods 16 are fixedly connected to the top of the center plate 8. The top of the limiting rods 16 are slidably connected to the mounting frame 5. The limiting rods 16 improve the stability of the center plate 8 when it moves.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
