Description

Technical Field

[0001] This utility model specifically relates to a paper storage mechanism for a non-stop unwinding machine, belonging to the technical field of unwinding machine paper storage equipment. Background Technology

[0002] In modern printing and packaging industries, production efficiency and product quality are key elements of a company's competitiveness. As an important material handling device in the industry, the performance of the paper storage mechanism of the non-stop unwinding machine directly affects the stability and efficiency of the entire production process.

[0003] Traditional non-stop unwinding paper storage mechanisms have significant shortcomings in paper tension regulation. Due to the lack of precise tension control devices, the tension of the paper fluctuates greatly during unwinding, which can easily lead to problems such as wrinkles and tears. This not only causes a large amount of paper waste and increases production costs, but also frequently requires machine shutdowns to deal with paper problems, which seriously reduces production efficiency. In addition, these paper storage mechanisms have a low degree of automation and require frequent manual operation, which not only consumes a lot of manpower, but also the differences in human operation can easily lead to operational errors, making it difficult to ensure the consistency and stability of the operation process.

[0004] As the industry's requirements for production efficiency and product quality continue to increase, the drawbacks of traditional paper storage mechanisms are becoming increasingly apparent, and they can no longer meet the demands of high-speed, high-quality production. Against this backdrop, developing a paper storage mechanism for a non-stop unwinding machine with precise tension adjustment and a high degree of automation has become an urgent problem for the industry.

[0005] In view of this, this utility model is proposed. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by providing a paper storage mechanism for a non-stop unwinding machine, so as to achieve precise tension adjustment of the paper.

[0007] This utility model achieves the above-mentioned objective through the following technical solution: a paper storage mechanism for a non-stop unwinding machine, comprising two vertically arranged upright plates connected by a top plate, a fixed roller rotatably mounted between the upright plates, a vertically sliding lifting paper storage roller mounted between the upright plates, multiple cross-line guide rollers of various models rotatably mounted at the bottom between the upright plates, and a drive box fixedly mounted on one side of one of the upright plates, the drive box containing a drive assembly for driving the vertical movement of the lifting paper storage roller.

[0008] Furthermore, in order to limit the slider, guide rails are fixedly installed on the adjacent and opposite surfaces of the two upright plates, and sliders are slidably engaged on the guide rails.

[0009] Furthermore, in order to connect the tension roller to the slider, the lifting paper storage roller assembly includes two connecting plates and four tension rollers. The tension rollers are rotatably mounted between the two connecting plates, and the connecting plates at both ends of the tension rollers are fixedly connected to the slider through a fixing frame.

[0010] Furthermore, in order to raise and lower the drive pulley via the drive cylinder, and thus enable the lifting and lowering of the paper storage roller on the slider controlled by the drive rope, the drive assembly includes a drive cylinder and a drive pulley. The drive cylinder is disposed inside the drive box and is fixedly connected to the upright plate. The drive pulley is fixedly installed on the output end of the drive cylinder. A drive rope is wound around the drive pulley. Fixed pulleys are fixedly installed at the top of both upright plates. The two ends of the drive rope are respectively wound around the two fixed pulleys and fixedly connected to the slider on the upright plate.

[0011] Furthermore, in order to supply oil to the drive cylinder and thus enable the drive cylinder to extend and retract, an oil reservoir is fixedly connected to the drive cylinder. The oil reservoir is disposed inside the drive box and is fixedly connected to the vertical plate.

[0012] Furthermore, in order to improve the response speed of the drive cylinder, a speed-increasing relay is provided in the drive box, and the speed-increasing relay is fixedly connected to the vertical plate.

[0013] Furthermore, in order to control the speed of the movement of the drive rope, a buffer is fixedly installed on one side of the upright plate.

[0014] Furthermore, to facilitate wiring, a right-angle connector pipe is fixedly installed on one side of the bottom end of the upright plate by means of sheet metal mounting.

[0015] The beneficial effects of this utility model are: through the cooperation of the drive components and lifting paper storage rollers, this device can have a precise tension adjustment function, which greatly improves the stability of paper conveying. When the unwinding machine is running, the stable paper tension can avoid problems such as paper wrinkling and breaking, reduce the scrap rate, greatly improve production efficiency, and reduce production costs.

[0016] Furthermore, this device is highly automated, and the automated operation mode reduces the need for manual intervention, which not only reduces labor costs but also avoids errors caused by improper human operation, ensuring the consistency and stability of the work process.

[0024] 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.

[0025] Please see Figures 1-6 As shown, a paper storage mechanism for a non-stop unwinding machine includes two vertically arranged upright plates 1, which are connected by a top plate 2. A fixed roller 3 is rotatably installed between the upright plates 1, and a vertically sliding lifting paper storage roller 4 is installed between the upright plates 1. Multiple cross-line guide rollers 5 of various models are rotatably installed at the bottom between the upright plates 1. A drive box 6 is fixedly installed on one side of one upright plate 1, and a drive assembly 7 for driving the vertical movement of the lifting paper storage roller 4 is provided inside the drive box 6.

[0026] like Figure 4 As shown, guide rails 8 are fixedly installed on the adjacent and opposite surfaces of the two upright plates 1. Sliding blocks 9 are slidably engaged on the guide rails 8. It should be noted that the guide rails 8 are installed on the upright plates 1 by appropriate screws or bolts.

[0027] like Figure 3 and Figure 6As shown, the lifting paper storage roller assembly 4 includes two connecting plates 401 and four tension rollers 402. The tension rollers 402 are rotatably mounted between the two connecting plates 401. The connecting plates 401 at both ends of the tension rollers 402 are fixedly connected to the slider 9 through the fixing bracket 403. The drive assembly 7 includes a drive cylinder 701 and a drive pulley 702. The drive cylinder 701 is located inside the drive box 6 and fixedly connected to the vertical plate 1. The drive pulley 702 is fixedly mounted on the output end of the drive cylinder 701. The drive pulley 702 is wound with a... The drive rope 703 has fixed pulleys 10 fixedly installed at the top of both upright plates 1. The two ends of the drive rope 703 are respectively wound around the two fixed pulleys 10 and fixedly connected to the slider 9 on the upright plate 1. This allows the drive assembly 7 to move the drive rope 703 wound around the drive pulley 702 by extending and retracting the drive cylinder 701. Then, by supporting the drive rope 703 through the fixed pulleys 10, the paper storage roller 4 can be raised and lowered to move up and down, thereby adjusting the conveying tension of the paper wound around the paper storage roller 4.

[0028] like Figure 3 As shown, an oil reservoir 11 is fixedly connected to the drive cylinder 701. The oil reservoir 11 is located inside the drive box 6 and is fixedly connected to the vertical plate 1. An acceleration relay 12 is installed inside the drive box 6 and is fixedly connected to the vertical plate 1. A buffer 13 is fixedly installed on one side of the vertical plate 1. A right-angle connector pipe 15 is fixedly installed on one side of the bottom end of the vertical plate 1 through a mounting sheet metal 14. An electronic ruler 16 is fixedly installed on one side of the vertical plate 1 so that the lubricating oil in the oil reservoir 11 can be introduced into the drive cylinder 701 through an external oil pump, thereby causing the telescopic end of the drive cylinder 701 to extend. When the cylinder 701 retracts, it can drive the pulley 702 to move. The external oil pump is controlled by the external controller. Since the above structures are common existing technologies on the market, the structure of this device is not described. When the extension end of the drive cylinder 701 moves, the displacement of the extension end of the drive cylinder 701 can be detected by the electronic ruler 16. Then, through the electrical connection between the electronic ruler 16 and the external controller, the extension displacement of the drive cylinder 701 can be monitored. The movement of the drive cylinder 701 is linked with the movement of the lifting paper storage roller 4, thereby realizing precise displacement control of the lifting paper storage roller 4, which is highly practical.
