Description

Technical Field

[0001] This utility model relates to the field of cement packaging bag processing technology, and in particular to a processing equipment for folding cement packaging bags. Background Technology

[0002] As an important packaging medium for cement products, the processing quality of cement bags directly affects the safety of cement storage and transportation. Folding is a key process in cement bag production; folding creates a regular structure at the bag opening, facilitating subsequent sealing and improving the bag's airtightness and structural stability.

[0003] The patent publication number "CN222959352U" discloses "A processing device for folding cement packaging bags," which includes a frame, a conveyor, and auxiliary devices. The auxiliary devices include a mounting frame, a push plate, a mating plate, a detection sensor, a first drive assembly, a second drive assembly, and a guide assembly. During processing, the conveyor transports the cement-filled packaging bags. After the detection sensor detects the arrival signal, the conveyor stops. Then, the first drive assembly moves, pushing the push plate to move. Simultaneously, the second drive assembly moves, pushing the mating plate to move. After the push plate moves, it engages in the U-shaped groove of the mating plate, thereby folding the bag opening. This achieves automatic folding of the cement packaging bag opening during processing, which helps improve work efficiency.

[0004] However, the aforementioned equipment uses a manual folding method, which is not only labor-intensive and inefficient, but also prone to inconsistent folding angles and irregular folds due to human error, affecting the subsequent sealing quality and the overall aesthetics of the packaging bag. Some automated folding equipment has an unreasonable folding mechanism design, which can cause the packaging bag to shift or wrinkle during the folding process. Furthermore, the folded packaging bag is not smoothly fed, requiring additional manual intervention to straighten it, which further reduces production efficiency. Utility Model Content

[0019] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0020] reference Figures 1-5This utility model provides a technical solution: a processing device for folding cement packaging bags, including a base 1, a folding assembly 2 on one side of the base 1 for folding the cement packaging bags; and a feeding assembly 3 on one side of the base 1 for feeding and collecting the folded packaging bags. The folding assembly 2 includes a mounting platform 21, which is fixedly installed on one side of the base 1. A placement groove 213 is formed on the top of the mounting platform 21, and a horizontal lead screw 22 is rotatably connected to the inner wall of the placement groove 213. The horizontal lead screw 22 is a high-precision ball screw to ensure accurate transmission; its core function is to drive the turntable 26 to move precisely to one side of the receiving groove 212. A nut block 23 is threadedly connected to the outer wall of the horizontal lead screw 22, and a reinforcing ring 25 is fixedly connected to the top of the nut block 23. The reinforcing ring 25 is made of high-strength metal material to ensure structural stability. A turntable 26 is rotatably connected to the inner wall of the reinforcing ring 25. A folding and winding rod 27 is fixedly connected to one side of the turntable 26. The surface of the folding and winding rod 27 is smoothed to avoid scratching the cement packaging bag. Two folding and winding rods 27 are symmetrically arranged on one side of the turntable 26 to ensure precise vertical alignment after movement. A first servo motor 24 is also fixedly connected to the top of the nut block 23. The first servo motor 24 is a servo motor with a reduction mechanism, which can precisely control the speed and angle. The output shaft of the first servo motor 24 is fixedly connected to one side of the turntable 26 to drive the turntable 26 to rotate the folding and winding rod 27. A second servo motor 210 is fixedly connected to one side of the mounting platform 21. The second servo motor 210 is also a high-precision servo motor. Its output shaft is fixedly connected to one end of the horizontal lead screw 22 to provide power for the rotation of the horizontal lead screw 22. A limiting slide rod 29 is fixedly connected between the inner walls of the placement groove 213 and the horizontal lead screw 22. The limiting slide rod 29 passes through the nut block 23 and is slidably connected to its interior. The surface of the limiting slide rod 29 is coated with lubricating oil to reduce friction with the nut block 23, ensuring that the nut block 23 drives the turntable 26 to move smoothly in a straight line, and avoiding deviation that would prevent the two folding and winding rods 27 from being accurately aligned vertically. A roller 28 is fixedly connected to the bottom of the nut block 23. The roller 28 is made of wear-resistant rubber and is rolled to the inner bottom of the placement groove 213. Rolling friction replaces sliding friction, reducing movement resistance and making the movement of the nut block 23 driving the turntable 26 towards the receiving groove 212 more smooth and efficient. The top of the base 1 is provided with a receiving groove 212. The size of the receiving groove 212 is adapted to the folding requirements of the cement packaging bag. The distance between the two folding and winding rods 27 is smaller than the receiving groove 212. When the two folding and winding rods 27 are facing each other, one of the folding and winding rods 27 is located above the base 1, and the other folding and winding rod 27 is located in the receiving groove 212, forming an upper and lower clamping structure to provide stable support for winding and folding.The folding assembly 2 also includes a conveyor 211, which is a belt conveyor with adjustable conveying speed. One end of the conveyor 211 is directly opposite the receiving groove 212. A docking slide 214 is fixedly connected to one side of the base 1. The top of the docking slide 214 is flush with the top of the base 1 and the top of the conveyor 211. The surface of the docking slide 214 is smoothed to reduce the frictional resistance when the packaging bag is conveyed, ensuring that the packaging bag is accurately conveyed to the receiving groove 212 and precisely aligned with the folding and winding rods 27 that are opposite each other.

[0021] Reference Figures 1-5 In one aspect of this embodiment, the feeding assembly 3 includes a horizontal cylinder 31. The horizontal cylinder 31 is a standard cylinder with stable thrust output. The horizontal cylinder 31 is fixedly connected to the top of the base 1. A first push plate 32 is fixedly connected to the movable end of the horizontal cylinder 31. The first push plate 32 is wrapped with a flexible material to avoid damaging the packaging bag. The first push plate 32 is located on one side of the receiving groove 212. A vertical cylinder 35 is fixedly connected inside the base 1. The vertical cylinder 35 is matched with the model of the horizontal cylinder 31. A second push plate 36 is fixedly connected to the movable end of the vertical cylinder 35. The size of the second push plate 36 is adapted to the width of the receiving groove 212. In the initial state, the bottom of the second push plate 36 is in contact with the inner bottom of the receiving groove 212. A sloping slide plate 33 is fixedly connected to one side of the base 1. The sloping slide plate 33 is made of smooth metal plate and the tilt angle is set to 30-45° to facilitate the sliding of the packaging bag. The feeding component 3 also includes a collection box 34. The collection box 34 is made of high-strength plastic or metal material. The collection box 34 is located below one end of the sloping slide plate 33. A cushioning pad can be laid inside the collection box 34 to prevent the packaging bag from being damaged when it falls.

[0022] Working Principle: When this processing equipment for folding cement packaging bags is in operation, it first adjusts the distance between the two folding and winding rods 27 according to the specifications and dimensions of the cement packaging bag to be processed, and moves them precisely to one side of the receiving groove 212. The second servo motor 210 is then started. The output shaft of the second servo motor 210 drives the horizontal lead screw 22 to rotate within the placement groove 213. Since the nut block 23 is threadedly connected to the horizontal lead screw 22, and the limiting slide rod 29 provides a limiting and guiding function for the nut block 23, the nut block 23 moves smoothly towards one side of the receiving groove 212 along the length direction of the horizontal lead screw 22 and the limiting slide rod 29. Simultaneously, the roller 28 at the bottom of the nut block 23 rolls at the bottom of the placement groove 213, reducing movement resistance. When the nut block 23 drives the turntable 26 to a preset position on one side of the receiving groove 212, the two folding and winding rods 27 are precisely aligned vertically. At this point, the second servo motor 210 is turned off, completing the positioning adjustment. The cement bag to be folded is placed on the conveyor 211. The conveyor 211 is started, and the bag moves under its drive, smoothly conveyed to the top of the base 1 via the docking slide 214. The part of the bag to be folded precisely aligns above the receiving groove 212, positioned between the two opposing folding and winding rods 27. The first servo motor 24 is started, and its output shaft drives the turntable 26 to rotate on the inner wall of the reinforcing ring 25. The turntable 26 drives the two opposing folding and winding rods 27 to rotate synchronously. The folding and winding rods 27 located above the base 1 and those located in the receiving groove 212 work together to wrap and fold the part of the cement bag to be folded. The first servo motor 24 precisely controls the rotation angle and speed of the folding and winding rods 27 to ensure that the folded edges of the bag are neat and the angles are consistent. After the winding and folding is completed, the vertical cylinder 35 is activated. The movable end of the vertical cylinder 35 drives the second push plate 36 to move upward, lifting the packaging bag in the receiving groove 212 and causing the packaging bag to detach from the receiving groove 212. Then, the horizontal cylinder 31 is activated. The movable end of the horizontal cylinder 31 drives the first push plate 32 to move closer to the inclined slide plate 33. The first push plate 32 pushes the wound and folded packaging bag onto the inclined slide plate 33. Under the action of gravity, the packaging bag slides down the inclined slide plate 33 and finally falls into the collection box 34, completing the unloading and centralized collection. By repeating the above steps, the continuous automated winding and folding processing of cement packaging bags can be realized.

[0023] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
