Abstract
Description
Technical Field
[0001] This utility model relates to the field of slitting machines, specifically a tray pushing device for a paper receiving mechanism. Background Technology
[0002] The paper slitting machine cuts rolls of paper into different sizes, such as A4 and A3. The paper collection mechanism collects the slitting paper onto a tray on the lifting platform. As the paper is stacked, the lifting platform gradually lowers until it reaches its lowest position. At this point, the tray needs to be replaced. The tray and stacked paper on the lifting platform are output from the front, in the same direction as the slitting paper is conveyed. The new tray is pushed in from the side of the lifting platform.
[0003] Existing pallet pushers include single-stage and two-stage pushers. Single-stage pushers involve a single set of transmission components driving the pusher plate to move. Single-stage pushers require a long pushing time and a large space for installing the transmission components. Two-stage pushers involve two sets of transmission components driving the pusher plate to move. Although the pushing efficiency is high, it requires two power sources, resulting in higher equipment costs. Utility Model Content
[0004] In view of the technical problems existing in the background art, the technical problem solved by this utility model is to provide a pallet pushing device for a paper receiving mechanism with high pushing efficiency and low separation cost.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: the pallet pushing device of this paper receiving mechanism is characterized in that it includes a frame, a push plate, and a transmission component for driving the push plate to move horizontally.
[0006] The transmission component includes a motor, a main beam, and an extension arm;
[0007] -The motor is mounted on the extension arm, and a gear is mounted on the output shaft of the motor;
[0008] -The extension arm is provided with a front synchronous pulley, a rear synchronous pulley and a first guide rail. The front synchronous pulley and the rear synchronous pulley are provided with an annular synchronous belt. The synchronous belt is equipped with a first fixed seat and a second fixed seat.
[0009] - The main beam is mounted on the frame. The main beam is provided with a rack and a second guide rail. The rack, the first guide rail, the second guide rail, and the timing belt are arranged in parallel and longitudinally. The gear meshes with the rack. The extension arm is slidably mounted on the second guide rail. The first fixed seat is connected to the main beam.
[0010] The push plate is arranged horizontally and slidably mounted on the first guide rail, and the second fixed seat is connected to the push plate;
[0011] When driven by a synchronous belt, the first fixed seat and the second fixed seat move in opposite directions, and the second movable seat moves in the same direction as the extension arm.
[0012] The motor drives the gear to rotate, which in turn runs on the rack, causing the extension arm to move along the second guide rail. As the extension arm moves, the first fixed seat pulls the synchronous belt to move, causing the second fixed seat and the push plate to move along the first guide rail. In other words, the push plate moves relative to the extension arm, achieving two-stage movement and doubling the pushing speed. This invention uses only one motor to achieve two-stage pushing, resulting in high production efficiency, a compact structure, and low equipment cost.
[0013] Preferably, the synchronous belt is divided into an upper section and a lower section, the first fixing seat is connected to the upper section, the second fixing seat is connected to the lower section, and the push plate is disposed below the extension arm;
[0014] A conveying platform is provided below the push plate, and the conveying platform is set at the same height as the lower lifting platform.
[0015] With the push plate at the bottom and the transmission structure at the top, it facilitates the transfer of the pallet and also makes maintenance of the transmission structure easier.
[0016] Preferably, the travel of the gear on the rack is shorter than the distance between the front and rear synchronizing pulleys. Attached Figure Description

Detailed Implementation
[0020] The following describes the embodiments and related details and working principle of this utility model with reference to the accompanying drawings. In the figures, the X-axis is horizontal, the Y-axis is vertical, and the Z-axis is vertical. The lifting platform is in front of the pallet 17 pushing device. The pallet 17 pushing device of this paper receiving mechanism includes a frame 1, a push plate 2, and a transmission component for driving the push plate 2 to move horizontally. The transmission component includes a motor 10, a main beam 4, and an extension arm 6. The motor 10 is mounted on the extension arm 6, and a gear 9 is mounted on the output shaft of the motor 10. The extension arm 6 is provided with a front synchronous pulley 13, a rear synchronous pulley 15, and a first guide rail 7. The front synchronous pulley 13 and the rear synchronous pulley 15 are provided with an annular synchronous belt 18. The synchronous belt 18 is equipped with a first fixed seat 14 and a second fixed seat 16. The main beam 4 is mounted on the frame 1. The main beam 4 is provided with a rack 8 and a second guide rail 5. The rack 8, the first guide rail 7, the second guide rail 5, and the timing belt 18 are arranged in parallel and longitudinally. The gear 9 meshes with the rack 8. The extension arm 6 is slidably mounted on the second guide rail 5. The first fixed seat 14 is connected to the main beam 4. The push plate 2 is arranged laterally and slidably mounted on the first guide rail 7. The second fixed seat 16 is connected to the push plate 2. When the timing belt 18 is driven, the first fixed seat 14 and the second fixed seat 16 move in opposite directions, and the movement direction of the second moving seat is consistent with the movement direction of the extension arm 6.
[0021] In the diagram, the push plate 2 is in a waiting state. The synchronous belt 18 is divided into an upper section 11 and a lower section 12. The first fixed seat 14 is connected to the upper section 11 and is located at the front end of the upper section 11, close to the paper receiving mechanism. The second fixed seat 16 is connected to the lower section 12 and is located at the rear end of the lower section 12, away from the paper receiving mechanism. The travel of the gear 9 rotating on the rack 8 is shorter than the distance between the front synchronous pulley 13 and the rear synchronous pulley 15. The push plate 2 is located below the extension arm 6. Below the push plate 2 is a conveying platform 3. The conveying platform 3 is set at the same height as the lower lifting platform. That is, when the pallet 17 on the lifting platform needs to be replaced, the height of the lowered lifting platform is the same as that of the conveying platform 3. At this time, the push plate 2 pushes the pallet 17 to move towards the lifting platform.
[0022] When pallet 17 is replaced, pallet 17 is placed on conveyor platform 3 in front of push plate 2. Motor 10 drives gear 9 to rotate, rack 8 remains stationary, and gear 9 moves forward on rack 8, causing extension arm 6 to move forward along second guide rail 5. First fixed seat 14 remains stationary on main beam 4. As extension arm 6 moves, the connection between first fixed seat 14 and synchronous belt 18 moves backward relative to extension arm 6, and lower section 12 of synchronous belt 18 moves forward, causing second fixed seat 16 and push plate 2 to move forward along first guide rail 7. That is, push plate 2 moves forward relative to extension arm 6, and push plate 2 pushes pallet 17 on conveyor platform 3 forward and pushes pallet 17 onto lifting platform. After pushing is completed, motor 10 rotates in the opposite direction, gear 9 moves backward on rack 8, extension arm 6 retracts, and similarly drives lower section 12 of synchronous belt 12 to move backward, causing push plate 2 to retract and reset. This invention uses only one motor 10 to achieve two-stage movement of the push plate 2, which doubles the pushing speed. Compared with the prior art, it has substantial features and progress.
