Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of paper-topping mechanisms, specifically to a paper-topping mechanism for a stacking suction unit. Background Technology
[0002] The original paper-lifting mechanism used a cylinder to lift the paper directly upwards, resulting in loud noise. When paper was on the surface, the cylinder rod was prone to lateral force, shortening the cylinder's lifespan. When the cylinder directly lifted the paper-lifting mechanism, it typically moved in a linear reciprocating motion. This motion resulted in rapid speed changes during start-up and stopping, generating significant inertial forces. Furthermore, the paper-lifting mechanism needed to bear the load of paper during operation. When paper was on the surface, the cylinder not only had to push against its own weight but also overcome the weight and friction of the paper. In this situation, the cylinder's working pressure might increase, affecting the smoothness of the movement and leading to increased impact between moving parts, thus increasing noise. This also caused rigid collisions between the paper-lifting component and the paper surface, resulting in noticeable noise. Therefore, we need to provide a paper-lifting mechanism for the stacking suction section. Utility Model Content
[0003] The purpose of this utility model is to provide a paper-topping mechanism for the stacking suction section. By setting a secondary rotating mechanism inside the machine body, the speed change of the paper-topping cylinder is gradual when it starts or stops, reducing the rigid collision between the paper-topping board and the paper, thereby reducing noise. During the paper-topping process, the swing arm is evenly stressed, and the load is distributed at the pulley fulcrum, avoiding wear of the original cylinder rod caused by lateral force, extending the service life of the mechanism, and solving the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a paper-top mechanism for a stacking suction section, comprising:
[0005] The machine body includes a conveying mechanism and a rotating joint mechanism. The machine body is equipped with a conveying mechanism for paper movement and a rotating joint mechanism for reducing the lateral force of the cylinder rod to achieve low noise.

The front belt is mounted on the surfaces of the pulley and two auxiliary shafts, which are distributed vertically and at the same height as the pulley, so as to achieve a parallel distribution of the top and bottom of the front belt.
[0009] Preferably, the swing arm includes a rotating disk and a rocking plate. The bottom protrusion of the rotating disk is hinged to the extension end of the top paper cylinder, and the rotating disk is rotatably sleeved on the surface of the pulley.

[0021] 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.
[0022] Please see Figure 1-4 This utility model provides a technical solution: a stacking suction unit top paper mechanism, comprising:
[0023] The machine body 1, the conveying mechanism 2, and the rotary joint mechanism 3 are provided. The machine body 1 is equipped with the conveying mechanism 2 for paper movement, and the machine body 1 is equipped with the rotary joint mechanism 3 for reducing the lateral force of the cylinder rod to achieve low noise.
[0024] The rotary joint mechanism 3 includes a paper-top cylinder 31, a swing arm 32, and a paper-top plate 33. The extended end of the paper-top cylinder 31 is hinged to the swing arm 32, and a paper-top plate 33 for pushing the paper to move is provided on one side of the swing arm 32.
[0025] Specifically, the paper-top cylinder 31 is located at the bottom of the conveying mechanism 2, and the extension end of the paper-top cylinder 31 is hinged to a swing arm 32. The paper-top plate 33 is fixed on the top of the swing arm 32. By setting a secondary rotation mechanism inside the machine body 1, the speed of the paper-top cylinder 31 changes smoothly when it starts or stops, reducing the rigid collision between the paper-top plate 33 and the paper, thereby reducing noise. During the paper-topping process, the swing arm 32 is evenly stressed, and the pulley 212 distributes the load at the fulcrum, avoiding wear of the original cylinder rod due to lateral force and extending the service life of the mechanism.
[0026] The conveying mechanism 2 includes a front conveyor 21 and a rear conveyor 22. The rotating pair mechanism 3 is installed inside the front conveyor 21. Both the front conveyor 21 and the rear conveyor 22 are installed inside the machine body 1.
[0027] Furthermore, both the front conveyor 21 and the rear conveyor 22 are controlled and started by external drivers. The rotary joint mechanism 3 is located between the front conveyor 21 and the rear conveyor 22. The front and rear conveyors 22 are independently controlled by external drivers, which can precisely coordinate the conveying rhythm. When the rotary joint mechanism 3 pushes the paper, it can use the belt of the front conveyor 21 to support the paper, and the rear conveyor 22 simultaneously conveys the subsequent paper, avoiding the interruption of the conveying. The rotary joint mechanism 3 is close to the center of the paper conveying path, and the paper pushing action directly acts on the paper between the front and rear conveyors 22, shortening the paper pushing distance and improving the response speed. The front conveyor 21 provides a mounting fulcrum for the rotary joint, and the rear conveyor 22 balances the paper conveying tension. The two and the rotary joint form a linkage structure, reducing paper offset when pushing the paper. At the same time, the compact layout saves space in the machine body 1 and optimizes the integration of the mechanism.
[0028] The front conveyor 21 includes a front belt 211, a pulley 212 and a secondary shaft 213. The front belt 211 is mounted on the surface of the pulley 212 and the two secondary shafts 213. The two secondary shafts 213 are distributed vertically and are at the same height as the pulley 212, so as to achieve the parallel distribution of the top and bottom of the front belt 211.
[0029] It is worth noting that the front belt 211 is fitted onto the surface of the pulley 212 and the two auxiliary shafts 213. The auxiliary shafts 213 are distributed vertically and are at the same height as the axis of the pulley 212, so that the top and bottom of the front belt 211 are kept parallel. When the pulley 212 rotates, it drives the front belt 211 to run in a cycle. The paper is placed on the top of the front belt 211 and moves horizontally to the designated position with the belt. The function of the auxiliary shafts 213 is to support the belt and maintain its tension, so as to ensure smooth belt transmission.
[0030] The rotating sub-mechanism 3 is installed inside the front conveyor 21. The rocker plate 322 of the swing arm 32 is located between the front and rear conveyors 22. When the paper is conveyed to the top paper position, the top paper cylinder 31 drives the swing arm 32 to lift the top paper plate 33 and lift the paper (in conjunction with the suction part to adsorb and stack the paper). After the top paper action is completed, the cylinder retracts and the swing arm 32 swings down to reset, without affecting the belt to continue conveying subsequent paper.
[0031] The swing arm 32 includes a rotating disk 321 and a rocker plate 322. The bottom protrusion of the rotating disk 321 is hinged to the extension end of the paper-top cylinder 31, and the rotating disk 321 is rotatably sleeved on the surface of the pulley 212. One end of the rocker plate 322 is fixed on the surface of the rotating disk 321 and is located between the front conveyor 21 and the rear conveyor 22.
[0032] The swing arm 32 consists of a rotating disk 321 and a rocker plate 322. The bottom protrusion of the rotating disk 321 is hinged to the paper-topping cylinder 31 and rotatably sleeved on the pulley 212. The rocker plate 322 is located between the front and rear conveyors 22. The rotating disk 321 rotates with the pulley 212 as the fulcrum, converting the linear thrust of the cylinder into rotational torque, avoiding lateral force on the cylinder rod and extending its service life. The rotatable sleeve structure between the rotating disk 321 and the pulley 212 makes the swing arm 32 swing more smoothly and reduces rigid friction noise. The rocker plate 322 is located between the front and rear conveyors 22, and can accurately act on the middle of the paper when it is being topped. The belt of the front conveyor 21 supports the paper, and the rear conveyor 22 maintains the tension. The three work together to reduce paper deviation. This structure is compactly integrated into the conveying path, and the paper-topping action is synchronized with the conveying rhythm, improving stacking efficiency.
[0033] The top plate 33 is fixed to the top of the rocker plate 322, and the surface of the top plate 33 is provided with a brush part 4;
[0034] It is worth noting that when the brush part 4 comes into contact with the paper, the flexible bristles reduce the rigid collision between the top plate 33 and the paper, reduce the paper-lifting noise, and at the same time avoid the paper surface from being indented or damaged due to hard contact. The flexible brush part 4 can also adapt to the lifting requirements of paper of different thicknesses, and enhance the adaptability of the mechanism to paper specifications by deforming and buffering the paper-lifting force.
[0035] The top of the conveying mechanism 2 is provided with a cleaning component 5, which includes a drive cylinder 51, a push rod 52, a mounting base 53, a transmission rod 54 and a cleaning brush 55. Several drive cylinders 51 are hinged on the top of the conveying mechanism 2. The extension end of the drive cylinder 51 is hinged with a push rod 52. The push rod 52 is rotatably mounted on the mounting base 53. The mounting base 53 is fixed on the surface of the machine body 1. The transmission rod 54 is fixedly installed inside the push rod 52. The bottom of the transmission rod 54 is provided with a cleaning brush 55.
[0036] It should be noted that the lifting and lowering of the cleaning brush 55 is controlled by the drive cylinder 51 through the push rod 52. When the drive cylinder 51 extends, the push rod 52 pushes the transmission rod 54 to swing down, thereby controlling the cleaning brush 55 to tilt and fit against the belt surface. As the belt runs, it scrapes off paper scraps and dust from the surface. When the drive cylinder 51 retracts, the cleaning brush 55 disengages from the belt, avoiding dry grinding.
[0037] The cleaning brush 55 is tilted, and the bottom of the cleaning brush 55 is in contact with the belt in the conveyor mechanism 2;
[0038] Specifically, the inclined cleaning brush 55 forms a certain angle with the belt to enhance the scraping effect, while reducing noise and belt wear through flexible contact.
[0039] A bracket 6 is fixedly installed inside the machine body 1. The top of the bracket 6 is connected to the paper-top cylinder 31 via a hinge seat 7 to enable the paper-top cylinder 31 to rotate.
[0040] The bracket 6 is fixed to the inner wall of the machine body 1, and the top of the bracket 6 is bolted to a hinge seat 7. The paper-top cylinder 31 is rotatably installed in the hinge seat 7, so that the paper-top cylinder 31 can rotate and ensure that the paper-top cylinder 31 can be used normally.
[0041] The paper-top cylinder 31 and the driver involved in this application are both implemented using existing mature technologies and connected to an external PLC control and power supply. This is a conventional technical means in this field, so their specific circuit connections, control logic and working process will not be described in detail.
[0042] After the device is started by the top paper cylinder 31, its extended end pushes the rotating disk 321 to rotate around the pulley 212 as the fulcrum.
[0043] The piston rod of the paper-topping cylinder 31 extends and pushes the bottom protrusion of the rotating disk 321, causing the rotating disk 321 to swing around the axis of the pulley 212. This causes the rocker arm 322 to lift upward, and the paper-topping plate 33 contacts and lifts the paper. The rocker arm 32 swings in an arc with the pulley 212 as the fulcrum. The speed changes smoothly when starting or stopping, reducing the rigid collision between the paper-topping plate 33 and the paper, thereby reducing noise. During the paper-topping process, the rocker arm 32 is evenly stressed, and the load is distributed at the fulcrum of the pulley 212, avoiding wear caused by the lateral force of the original cylinder rod and extending the service life of the mechanism.
[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
