Description

Technical Field

[0001] This utility model relates to the technical field of woven bag production equipment, specifically a stacking device for producing environmentally friendly plastic woven bags. Background Technology

[0002] Woven bags are a type of plastic bag. Their raw materials are generally various chemical plastic raw materials such as polyethylene and polypropylene. The production process of plastic woven bags requires multiple processes such as raw material processing, weaving, cutting, printing, and sewing.

[0003] Currently, after woven bags are produced, multiple woven bags need to be packed together. In the meantime, they need to be stacked. While the workers are packing a batch of woven bags at a time, the current method is for the workers to transfer the produced woven bags to the target stacking area one by one. This operation requires the workers to handle each woven strap. At the same time, during the stacking process, the workers need to manually press down the batch of woven bags to increase the storage space. However, this operation will increase the workload of the operators and is also very troublesome. Utility Model Content

[0004] In order to solve the above problems, the purpose of this utility model is to provide a stacking device for the production of environmentally friendly plastic woven bags.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a stacking device for producing environmentally friendly plastic woven bags, including mounting frames, two of which are symmetrically arranged and both are inverted U-shaped. Two symmetrically arranged conveyor belts are provided within the two mounting frames, with the ends of the conveyor belts rotatably mounted on the mounting frames. A first motor is fixedly installed on one of the mounting frames near the conveyor belt, and the output end of the first motor coaxially acts on the conveyor roller connected to the conveyor belt. Two symmetrically arranged horizontal plates are fixedly installed on the top of both mounting frames. An electric push rod is fixedly installed on the lower surface of the horizontal plates, and a horizontally arranged extrusion plate is fixedly installed at the output end of the electric push rod. The extrusion plate is located in the middle of the two conveyor belts. A placement platform is provided at the bottom between the two mounting frames, and a base plate is slidably mounted on the placement platform. A stacking plate is slidably mounted on the upper surface of the base plate, and the stacking plate is U-shaped and located directly below the extrusion plate.

[0006] Preferably, an auxiliary belt is provided between the two conveyor belts, and the end of the auxiliary belt is rotatably mounted on the mounting frame via a conveyor roller. A symmetrically arranged support plate is fixed on the side wall of the mounting frame near the auxiliary belt, and a limiting roller is rotatably mounted on the support plate above the conveyor belt and the auxiliary belt.

[0007] Preferably, the bottom of the display platform is fixedly provided with a long plate, and the two ends of the long plate are slidably provided with sliders. The upper surface of the sliders and the lower surface of the bottom plate are hinged together with two adjusting rods arranged in an "eight" shape. The long plate is provided with a lead screw that rotates inside, and the two ends of the lead screw have opposite threads. A second motor is fixedly installed on the outer wall of the display platform near the lead screw, and the output end of the second motor is coaxially fixed on the lead screw.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0009] 1. The first motor drives the conveyor belt and auxiliary belt to automatically transport woven bags to the extrusion plate, eliminating the need for staff to transfer woven bags one by one, thus reducing the time and process of manual transfer; the electric push rod pushes the extrusion plate to automatically squeeze the woven bags onto the stacking plate, realizing the automatic stacking of woven bags, replacing manual stacking, and greatly speeding up the stacking speed.

[0010] 2. As the number of woven bags increases, the second motor controls the lead screw to rotate, causing the slider and adjusting rod to move, which in turn moves the stacking plate downwards to provide storage space for new woven bags. At the same time, the continuous squeezing of the extrusion plate can compress the gap between adjacent woven bags, further reducing the space occupied. This allows for the stacking of more woven bags at once, improving the storage range and space utilization. Attached Figure Description

[0016] 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.

[0017] Example: Figure 1-3 As shown, this utility model provides a stacking device for producing environmentally friendly plastic woven bags, including a mounting frame 1. Two mounting frames 1 are arranged symmetrically and are both inverted U-shaped. Two symmetrically arranged conveyor belts 11 are provided in the two mounting frames 1. The ends of the conveyor belts 11 are rotatably mounted on the mounting frames 1. A first motor 12 is fixedly installed on one of the mounting frames 1 near the conveyor belt 11. The output end of the first motor 12 acts coaxially on the conveyor roller 14 connected to the conveyor belt 11. Two symmetrically arranged horizontal plates 2 are fixedly fixed on the top of the two mounting frames 1. An electric push rod 21 is fixedly installed on the lower surface of the horizontal plate 2. A horizontally arranged extrusion plate 22 is fixedly installed at the output end of the electric push rod 21. The extrusion plate 22 is located in the middle of the two conveyor belts 11. A placement platform 3 is provided at the bottom between the two mounting frames 1. A base plate 31 is slidably mounted on the placement platform 3. A stacking plate 32 is slidably mounted on the upper surface of the base plate 31. The stacking plate 32 is U-shaped and located directly below the extrusion plate 22.

[0018] Vertically positioned limiting rods 23 are fixed at the four corners of the extrusion plate 22. The top of the limiting rods 23 is movably inserted into the horizontal plate 2. The limiting rods 23 mainly support the smooth movement of the extrusion plate 22 to prevent it from tilting up, which would cause the extrusion plate 22 to be unable to move stably to the target position when extruding the woven bag.

[0019] An auxiliary belt 13 is provided between the two conveyor belts 11. The end of the auxiliary belt 13 is rotatably mounted on the mounting frame 1 via a conveyor roller 14. The auxiliary belt 13 is mainly used to prevent the middle end of the woven bag being dented during transportation, ensuring stability during transportation. It is worth noting that the conveyor roller 14 on the auxiliary belt 13 and the conveyor roller 14 on the conveyor belt 11 can be connected by a chain and sprocket to ensure consistent transmission. At the same time, the end of the conveyor belt 11 and the auxiliary belt 13 away from the mounting frame 1 in this patent is also connected to the conveyor roller 14 via another mounting frame 1, which is the same type of structure as conventional belt conveyors on the market. Since this technology is too mature and publicly available, it will not be described in detail here. A symmetrically arranged support plate 15 is fixed on the side wall of the mounting frame 1 near the auxiliary belt 13. A limiting roller 16 is rotatably mounted on the support plate 15 above the conveyor belt 11 and the auxiliary belt 13. The limiting roller 16 limits the woven bag being transported on the conveyor belt 11 and the auxiliary belt 13 to prevent deviation and affect the normal transportation.

[0020] A handle 33 is fixedly provided at one end of the stacking board 32. The handle 33 makes it convenient for staff to directly pull out the stacking board 32 and transfer the woven bags on the stacking board 32.

[0021] A long plate 34 is fixedly installed at the bottom of the display platform 3. Sliding blocks 36 are slidably installed at both ends of the long plate 34. Two adjusting rods 37 arranged in an "eight" shape are hinged together between the upper surface of the slider 36 and the lower surface of the base plate 31. A lead screw 35 is rotatably installed inside the long plate 34, and the threads at both ends of the lead screw 35 are opposite. A second motor 38 is fixedly installed on the outer wall of the display platform 3 near the lead screw 35. The output end of the second motor 38 is coaxially fixed on the lead screw 35. The second motor 38 mainly provides power for the rotation of the lead screw 35, which is convenient for the staff to operate.

[0022] Working principle: During use, the conveyor belt 11 and auxiliary belt 13 are driven by the first motor 12. Workers only need to place the produced woven bags on the conveyor belt 11 and auxiliary belt 13. As the woven bags are moved by the conveyor belt 11 to below the extrusion plate 22, the electric push rod 21 pushes the extrusion plate 22 downwards, directly pushing the woven bags off the conveyor belt 11 and onto the stacking plate 32. As the number of woven bags increases, the extrusion plate 22 continuously extrudes the bags and moves them onto the stacking plate 32, completing the centralized stacking of the woven bags. During this process, as the number of woven bags increases... As more and more bags accumulate, to prevent the top of the stacking plate 32 from detaching from the display stand 3, the second motor 38 can control the lead screw 35 to rotate. At this time, the sliders 36 threaded at both ends of the lead screw 35 will move in opposite directions simultaneously. At this time, the adjusting rod 37 hinged between the slider 36 and the base plate 31 will gradually move to a horizontal state. At this time, the base plate 31 at the top will drive the stacking plate 32 to gradually move down. At this time, there will be more storage space between the stacking plate 32 and the display stand 3. At the same time, as the extrusion plate 22 moves down and extrudes, each extrusion can compress the adjacent woven bags, thereby further reducing the space occupied and allowing more bags to be stacked and packaged in sequence.

[0023] After the woven bags are stacked on the stacking platform 3 through the above operations, another worker can come and pull out the stacking board 32 to transfer the stacked woven bags on the stacking board 32 in one go, which greatly improves the stacking efficiency and reduces the workload of the workers.

[0024] All standard parts used in this invention can be purchased from the market, and irregularly shaped parts can be customized according to the description and drawings. The specific connection methods of each part all adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts, and equipment all adopt conventional models in the prior art, and the circuit connections adopt conventional connection methods in the prior art, which will not be described in detail here.

[0025] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
