Description

Technical Field

[0001] This utility model relates to the technical field of paper conveying equipment, and in particular to a paper cup paper conveying equipment with automatic correction function. Background Technology

[0002] The paper cup raw paper conveying equipment with automatic correction function is a key piece of equipment on the paper cup production line. It is used to convey paper and can detect the deviation of the raw paper in real time through sensors and automatically adjust its position with the help of the drive mechanism. It can ensure the accurate conveying of raw paper, reduce problems such as printing misalignment and die-cutting inaccuracy caused by deviation, improve production efficiency, reduce raw material waste, ensure product quality stability, and adapt to the conveying needs of raw paper of different specifications. It is an important piece of equipment to ensure the stability and economy of paper cup production.

[0003] However, in existing technologies, cylinders are often used to drive and adjust the tilt angle of the correction roller during the correction operation to adjust the friction force on both sides of the paper during the conveying process, thereby correcting the position of the paper. Since the cylinder relies on air pressure changes to achieve the action, the physical process of filling and releasing air causes a response delay, which is difficult to match the real-time adjustment requirements of high-speed production lines. Moreover, the air pressure is easily affected by pipeline resistance and air source fluctuations. In addition, the equipment does not dynamically adapt to the characteristics of the raw paper and the conveying speed, which makes the tilt angle adjustment range mismatched with the actual offset requirements. This ultimately leads to the accumulation of raw paper offset or reverse offset, resulting in response lag, insufficient adjustment accuracy, and easy to cause over-correction or under-correction problems. Utility Model Content

[0004] The purpose of this invention is to solve the problems existing in the prior art by proposing a paper cup base paper conveying device with automatic correction function.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a paper cup raw paper conveying device with automatic correction function, including a fixed frame, a feeding mechanism installed on the upper part of the fixed frame, and a correction mechanism installed on the side of the fixed frame. The feeding mechanism includes a first mounting frame, and a feeding roller assembly is installed inside the first mounting frame. The correction mechanism includes a fixed plate, a correction roller, and a base. A horizontal moving component is fixedly connected to the upper part of the fixed plate, and a connecting plate is fixedly connected to the upper part of the horizontal moving component. A first wedge block is fixedly connected to the upper part of the connecting plate, and a second wedge block is slidably connected to the upper part of the first wedge block. A first connecting frame is fixedly connected to the upper part of the second wedge block. The base is fixedly connected to the correction roller, and a third mounting frame is rotatably connected to the upper part of the base. One end of the correction roller is rotatably connected to the first connecting frame, and the other end of the correction roller is rotatably connected to the third mounting frame.

[0006] Preferably, the horizontal moving component includes a second mounting bracket, a first servo motor is fixedly connected to the upper part of the second mounting bracket, a lead screw is fixedly connected to the output end of the first servo motor, a lead block is threaded onto the surface of the lead screw, and the lead block is fixedly connected to the connecting plate.

[0007] Preferably, a slide rail is fixedly connected to the upper part of the second mounting bracket, and a slider is slidably connected to the surface of the slide rail, with the slider being fixedly connected to the bottom of the connecting plate.

[0008] Preferably, a second servo motor is fixedly connected to the upper part of the first connecting frame, and the output end of the second servo motor is fixedly connected to the end of the correction roller.

[0009] Preferably, a limiting groove is provided on the surface of the first wedge block, and a limiting plate is fixedly connected to the bottom of the second wedge block. The limiting plate is located inside the limiting groove and is slidably connected to the first wedge block.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0011] 1. In this utility model, a servo motor drives a lead screw to move the lead block and connecting plate horizontally. Combined with the wedge surfaces of the first and second wedge blocks, the horizontal movement is converted into precise vertical lifting and lowering. This allows one end of the correction roller to rise and fall with the second wedge block while the other end rotates around the base, achieving precise adjustment of the tilt angle. Compared to traditional cylinder drive, the combination of the servo motor and lead screw eliminates the problem of air pressure delay, resulting in a faster response speed. Furthermore, the mechanical amplification effect of the wedge surface improves the adjustment accuracy. It can dynamically adapt to the characteristics of the raw paper and the conveying speed based on the offset data fed back by the external monitoring system, avoiding over-correction or under-correction. This effectively solves the problem of offset accumulation caused by response lag and adjustment errors in high-speed production, improving the stability of paper cup raw paper conveying and product quality.

[0012] 2. In this utility model, the horizontal movement of the connecting plate is guided and limited by the sliding cooperation between the slide rail and the slider, eliminating the shaking problem caused by lateral force in the traditional structure and improving the straightness of the horizontal movement of the first wedge block; the sliding connection between the limiting groove and the limiting plate further constrains the relative displacement between the wedge blocks, avoiding the risk of misalignment caused by vibration or load changes, and ensuring the repeatability accuracy of the tilt angle adjustment; the direct drive of the second servo motor and the correction roller makes the roller surface linear speed and the paper conveying speed precisely synchronized, reducing the correction lag caused by slippage in the traditional friction transmission.

[0019] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Example 1: As Figures 1-4As shown, this utility model provides a paper cup raw paper conveying device with automatic correction function, including a fixed frame 1, a feeding mechanism 2 installed on the upper part of the fixed frame 1, and a correction mechanism 3 installed on the side of the fixed frame 1. The feeding mechanism 2 includes a first mounting frame 21, and a feeding roller assembly 22 is installed inside the first mounting frame 21. The correction mechanism 3 includes a fixed plate 31, a correction roller 311, and a base 312. A horizontal moving assembly is fixedly connected to the upper part of the fixed plate 31, and a connecting plate 36 is fixedly connected to the upper part of the horizontal moving assembly. A first wedge block 38 is fixedly connected to the upper part of the connecting plate 36, and a second wedge block 38 is slidably connected to the upper part of the first wedge block 38. The second wedge block 39 is fixedly connected to the upper part of the first connecting frame 310. The base 312 is fixedly connected to the straightening roller 311, and the upper part of the base 312 is rotatably connected to the third mounting frame 313. One end of the straightening roller 311 is rotatably connected to the first connecting frame 310, and the other end of the straightening roller 311 is rotatably connected to the third mounting frame 313. The horizontal moving component includes the second mounting frame 32. The upper part of the second mounting frame 32 is fixedly connected to the first servo motor 33. The output end of the first servo motor 33 is fixedly connected to the lead screw 34. The surface of the lead screw 34 is threaded with a thread block 35, and the thread block 35 is fixedly connected to the connecting plate 36.

[0022] The specific settings and functions of this embodiment are described below. Paper enters the feeding mechanism 2 through the upper part of the correction roller 311. The paper is fed by the feeding roller assembly 22. During the feeding process, the paper conveying status is monitored by an external monitoring system. When the paper deviates during the conveying process, the first servo motor 33 in the horizontal movement assembly drives the lead screw 34 to rotate, thereby driving the lead block 35 and the connecting plate 36 to move horizontally. This in turn drives the first wedge block 38 to move horizontally at the bottom of the second wedge block 39. The height of the second wedge block 39 is precisely adjusted by the wedge-shaped surface where the first wedge block 38 and the second wedge block 39 are in contact, so that the second wedge block 39 can be raised and lowered precisely. By raising and lowering the second wedge block 39 precisely, one end of the correction roller 311 can be raised and lowered, while the other end rotates along the base 312. This allows for precise adjustment of the friction between the paper and the surface of the correction roller 311, enabling fast and accurate correction of the paper.

[0023] The first servo motor 33 drives the lead screw 34, which in turn drives the lead block 35 and the connecting plate 36 to move horizontally. Combined with the wedge-shaped surfaces of the first wedge block 38 and the second wedge block 39, the horizontal movement is converted into precise vertical lifting and lowering. This allows one end of the correction roller 311 to rise and fall with the second wedge block 39, while the other end rotates around the base 312, achieving precise adjustment of the tilt angle. Compared with traditional cylinder drive, the combination of the first servo motor 33 driving the lead screw 34 eliminates the problem of air pressure delay, resulting in a faster response speed. Furthermore, the mechanical amplification effect of the wedge surface improves the adjustment accuracy. It can dynamically adapt to the characteristics of the raw paper and the conveying speed based on the offset data fed back by the external monitoring system, avoiding over-correction or under-correction. This effectively solves the problem of offset accumulation caused by response lag and adjustment error in high-speed production, improving the stability of paper cup raw paper conveying and product quality.

[0024] Example 2: Figures 2-5 As shown, a slide rail 37 is fixedly connected to the upper part of the second mounting bracket 32, and a slider 317 is slidably connected to the surface of the slide rail 37. The slider 317 is fixedly connected to the bottom of the connecting plate 36. A second servo motor 314 is fixedly connected to the upper part of the first connecting bracket 310. The output end of the second servo motor 314 is fixedly connected to the end of the correction roller 311. A limit groove 316 is provided on the surface of the first wedge block 38. A limit plate 315 is fixedly connected to the bottom of the second wedge block 39. The limit plate 315 is located inside the limit groove 316 and slidably connected to the first wedge block 38.

[0025] The overall effect of this embodiment is that the sliding cooperation between the slide rail 37 and the slider 317 guides and limits the horizontal movement of the connecting plate 36, eliminating the swaying problem caused by lateral force in the traditional structure and improving the straightness of the horizontal movement of the first wedge block 38; the sliding connection between the limiting groove 316 and the limiting plate 315 further constrains the relative displacement between the wedge blocks, avoiding the risk of misalignment caused by vibration or load changes, and ensuring the repeatability accuracy of the tilt angle adjustment; the direct drive of the second servo motor 314 and the correction roller 311 makes the roller surface linear speed and the paper conveying speed precisely synchronized, reducing the correction lag caused by slippage in the traditional friction transmission.

[0026] The device is used and operates as follows: Paper enters the feeding mechanism 2 through the upper part of the correction roller 311. The paper is fed by the feeding roller assembly 22. During the feeding process, the paper's conveying status is monitored by an external monitoring system. When the paper deviates during the conveying process, the first servo motor 33 in the horizontal movement assembly drives the lead screw 34 to rotate, thereby driving the lead block 35 and the connecting plate 36 to move horizontally. This, in turn, drives the first wedge block 38 to move horizontally at the bottom of the second wedge block 39. The height of the second wedge block 39 is precisely adjusted by the wedge-shaped surface where the first wedge block 38 and the second wedge block 39 are in contact, allowing the second wedge block 39 to be raised and lowered precisely. By precisely raising and lowering the second wedge block 39, one end of the correction roller 311 can be raised and lowered, while the other end rotates along the base 312. This allows for precise adjustment of the friction between the paper and the surface of the correction roller 311, enabling rapid and accurate correction of the paper's deviation.

[0027] During the horizontal movement of the connecting plate 36, the slider 317 slides along the slide rail 37 to limit the movement of the connecting plate 36 and improve the stability of the movement of the connecting plate 36. When the first wedge block 38 slides along the bottom of the second wedge block 39, the limiting plate 315 slides along the limiting groove 316 to limit the horizontal movement of the first wedge block 38 and improve the stability of the movement of the first wedge block 38.

[0028] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
