Description
Technical Field
[0001] This utility model relates to the technical field of receiving devices, specifically a receiving device for a paper unloader. Background Technology
[0002] In the paper processing industry, a paper unloader is a device used to safely and efficiently unload paper cut by a paper cutter on a printing intelligent cutting line. As an important supporting device for the paper unloader, the performance of the receiving device directly affects the operating efficiency, paper loss rate, and operational safety of the entire paper production line.
[0003] However, most existing receiving devices adopt an integrated fixed frame design. The size of the receiving platform cannot be adjusted according to paper specifications (such as A3, A4 and other papers of different widths and thicknesses). This can easily lead to paper shifting and falling, requiring manual handling, increasing costs and losses. Furthermore, the receiving device lacks an effective fixing mechanism, making it easy for paper stacks to tip over and scatter during transfer, which may cause equipment downtime or safety hazards.
[0004] Therefore, it is necessary to invent a receiving device for a paper unloader. Utility Model Content
[0005] The purpose of this invention is to provide a receiving device for a paper unloader to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a receiving device for a paper unloader, comprising a base plate, with symmetrically distributed L-shaped plates fixedly arranged on the top of the base plate, a horizontal plate fixedly arranged between two L-shaped plates, a second C-shaped plate slidably arranged at the bottom of the horizontal plate, a push plate rotatably arranged between the two side walls of the second C-shaped plate, a first C-shaped plate fixedly arranged on one side of the base plate, a rotating plate rotatably arranged between the two side walls of the first C-shaped plate, symmetrically distributed clamping plates slidably arranged on the top of the base plate, multiple casters fixedly arranged at the bottom of the base plate, and a handrail fixedly arranged at one top end of the base plate.
[0007] Preferably, the top of the horizontal plate is fixedly provided with symmetrically distributed fixed plates, and a corrugated telescopic tube is fixedly provided between the two fixed plates. A threaded rod is rotatably provided inside the corrugated telescopic tube, and a slider is threadedly sleeved on the outer wall of the threaded rod. The slider passes through the corrugated telescopic tube and a horizontal bar is fixedly provided at its end. A symmetrically distributed slider is fixedly provided at the bottom of the horizontal bar. The slider passes through the horizontal plate and is fixedly connected to the C-shaped plate.
[0008] Preferably, the top of the horizontal plate is provided with symmetrically distributed sliding grooves, and the second slider passes through the sliding grooves.
[0009] Preferably, a motor three is fixedly provided on one side of the C-shaped plate two, and the output shaft of the motor three passes through the C-shaped plate two and is fixedly connected to the push plate.
[0010] Preferably, a second motor is fixedly mounted on one side of the C-shaped plate, and the output shaft of the second motor passes through the C-shaped plate and is fixedly connected to the rotating plate.
[0011] Preferably, a motor is fixedly mounted on one side of one of the fixed plates, and the output shaft of the motor passes through one of the fixed plates and is fixedly connected to a threaded rod.
[0012] Preferably, a rectangular groove is provided in the base plate, and a corrugated telescopic tube II is fixed between the two side walls of the rectangular groove. A double-headed threaded rod II is rotatably provided in the corrugated telescopic tube II, and symmetrically distributed sliders III are threaded on the outer wall of the double-headed threaded rod II. The sliders III pass through the corrugated telescopic tube II and are fixedly connected to the base plate and the clamping plate.
[0013] Preferably, the top of the base plate is provided with a second sliding groove, and the third slider is slidably installed in the second sliding groove.
[0014] Preferably, a motor four is fixedly mounted on one side of the base plate, and the output shaft of the motor four passes through the rectangular slot and is fixedly connected to the double-threaded rod two.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] 1. In the initial stage of paper stack placement, the four-wheel drive clamping plates move in opposite directions by motor to complete the initial correction of the lateral dimensions and ensure the lateral alignment of the paper stack. After the paper stack is stacked to the preset quantity, the push plate pushes the paper stack to complete the secondary correction of the overall position, so as to avoid the paper stack shifting due to multiple layers of stacking. After correction, the push plate maintains a stable pushing force on the paper stack. Combined with the lateral limit of the clamping plates (before transfer), a "two-way fixed" structure is formed, which completely solves the problem of paper stack tipping over and falling off during the transfer of traditional devices.
[0017] 2. The casters allow a single worker to push the device to quickly connect to the paper unloader in different positions without relying on external hoisting equipment. The tilt angle of the turntable can be adjusted as needed during the unloading stage, and it can connect to the receiving plate for easy unloading. Attached Figure Description

Detailed Implementation
[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] Example: Figures 1-5 As shown, this utility model provides a receiving device for a paper unloader, including a base plate 1. The top of the base plate 1 is fixedly provided with symmetrically distributed L-shaped plates 12. A horizontal plate 13 is fixedly provided between two L-shaped plates 12. A second C-shaped plate 21 is slidably provided at the bottom of the horizontal plate 13. A push plate 23 is rotatably provided between the two side walls of the second C-shaped plate 21. A first C-shaped plate 17 is fixedly provided on one side of the base plate 1. A rotating plate 19 is rotatably provided between the two side walls of the first C-shaped plate 17. A clamping plate 35 is slidably provided on the top of the base plate 1. A plurality of universal wheels 36 are fixedly provided at the bottom of the base plate 1. A handrail 11 is fixedly provided at one end of the top of the base plate 1.
[0026] Furthermore, symmetrically distributed fixing plates 14 are fixedly provided on the top of the horizontal plate 13, and a corrugated telescopic tube 15 is fixedly provided between the two fixing plates 14. A threaded rod 16 is rotatably provided inside the corrugated telescopic tube 15, and a slider 161 is threadedly fitted on the outer wall of the threaded rod 16. The slider 161 passes through the corrugated telescopic tube 15 and a horizontal rod 162 is fixedly provided at its end. A symmetrically distributed slider 163 is fixedly provided at the bottom of the horizontal rod 162, and the slider 163 passes through the horizontal plate 13 and is connected to the horizontal plate 14. C-shaped plate 21 is fixedly connected, facilitating its forward and backward movement. Corrugated telescopic tube 15 wraps around threaded rod 16, allowing it to rotate and extend flexibly with the movement of threaded rod 16 and slider 161. This does not affect transmission and isolates threaded rod 16 from external impurities. The two ends of the tube are sealed with sealant at the fixing points of the two fixing plates 14 to prevent impurities from entering and ensure smooth transmission of threaded rod 16. Corrugated telescopic tube 22 has the same function as corrugated telescopic tube 15, both used to protect the internal threaded rod from interference by impurities.
[0027] Furthermore, the top of the horizontal plate 13 is provided with symmetrically distributed sliding grooves 131, and the second slider 163 passes through the sliding grooves 131 to facilitate the sliding of the second slider 163.
[0028] Furthermore, a motor 22 is fixedly provided on one side of the C-shaped plate 21. The output shaft of the motor 22 passes through the C-shaped plate 21 and is fixedly connected to the push plate 23 to facilitate the rotation of the push plate 23.
[0029] Furthermore, a second motor 18 is fixedly installed on one side of the C-shaped plate 17. The output shaft of the second motor 18 passes through the C-shaped plate 17 and is fixedly connected to the rotating plate 19 to facilitate the rotation of the rotating plate 19.
[0030] Furthermore, a motor 141 is fixedly mounted on one side of one of the fixed plates 14. The output shaft of the motor 141 passes through one of the fixed plates 14 and is fixedly connected to the threaded rod 16 to facilitate the rotation of the threaded rod 16.
[0031] Furthermore, a rectangular groove 312 is provided in the base plate 1, and a corrugated telescopic tube 32 is fixed between the two side walls of the rectangular groove 312. A double-headed threaded rod 33 is rotatably provided in the corrugated telescopic tube 32, and symmetrically distributed sliders 34 are threaded on the outer wall of the double-headed threaded rod 33. The sliders 34 pass through the corrugated telescopic tube 32 and are fixedly connected to the base plate 1 and the clamping plate 35. The double-headed threaded rod 33 is provided with threaded grooves at both ends, which facilitates driving the two clamping plates 35 to move in opposite directions or in opposite directions.
[0032] Furthermore, the top of the base plate 1 is provided with a second sliding groove 311, and the third slider 34 is slidably installed in the second sliding groove 311 to facilitate the sliding of the third slider 34.
[0033] Furthermore, a motor 31 is fixedly installed on one side of the base plate 1. The output shaft of the motor 31 passes through the rectangular groove 312 and is fixedly connected to the double-threaded rod 33, which facilitates the rotation of the double-threaded rod 33.
[0034] Working principle: When using this solution, firstly, multiple casters 36 are fixed at the bottom of the device base plate 1. The operator can hold the handrail 11 and use the rolling function of the casters 36 (the casters 36 are equipped with the existing conventional brake structure model: 7360123-626 model casters from Shanhoude Casters Manufacturing Co., Ltd.) to move the entire receiving device until it is adjusted to a suitable position aligned with the paper outlet of the paper unloader, ensuring that subsequent paper can fall accurately into the device, laying the positional foundation for the receiving work;
[0035] Then motor 22 can be started, which will drive push plate 23 to rotate as follows. Figure 1 As shown, after multiple paper stacks are placed on the base plate 1, the motor 31 fixed on one side of the base plate 1 is started, which in turn drives the double-headed threaded rod 33 to rotate inside the corrugated telescopic tube 32. The corrugated telescopic tube 32 can protect the double-headed threaded rod 33 from impurities. Since the threads at both ends of the double-headed threaded rod 33 rotate in opposite directions, the symmetrically distributed sliders 34 will move towards each other, which in turn drives the two clamping plates 35 to move towards each other until the clamping plates 35 are in close contact with both sides of the paper, thereby correcting the paper stack and preventing the paper stack from shifting laterally on the base plate 1.
[0036] Once the preset number of paper stacks on the base plate 1 is reached, motor 22 is restarted, causing pusher plate 23 to rotate until it is perpendicular to the base plate 1. Then, motor 141 is started, causing threaded rod 16 to rotate, which in turn causes slider 161 and crossbar 162 to move closer to rotating plate 19. During this process, corrugated telescopic tube 15 will extend and retract with slider 161, protecting threaded rod 16 from dust and paper scraps. This will cause slider 263 and C-shaped plate 21 to move closer to rotating plate 19. During the movement of C-shaped plate 21, pusher plate 23 in a vertical position will continuously adhere to the paper stack and apply a stable pushing force towards rotating plate 19. On the one hand, this will perform secondary correction of the paper stack to ensure overall alignment; on the other hand, it will firmly fix the paper stack to the base plate 1 to prevent the paper stack from detaching from the base plate 1 during subsequent transfer, thus ensuring the safety of the transfer.
[0037] When unloading is required, motor 431 can be reversed to move clamping plates 35 in opposite directions, thus releasing the paper and relieving the lateral fixation of the paper stack. Then, motor 218 is started, which drives the rotating plate 19 to rotate downward, causing the rotating plate 19 to tilt. The lower end of the rotating plate 19 connects with the receiving plate of the paper stack, forming a stable unloading channel. Then, motor 141 is started, which drives the threaded rod 16 to rotate again, which in turn drives the slider 161 and the crossbar 162 to move closer to the rotating plate 19. During this process, the slider 263 and the C-shaped plate 21 are also driven to move closer to the rotating plate 19, further driving the push plate 23 to move closer to the rotating plate 19. The push plate 23 pushes the paper stack along the bottom plate 1 towards the rotating plate 19. When the paper stack contacts the tilted rotating plate 19, it will slide naturally along the tilted surface of the rotating plate 19 and finally be smoothly unloaded onto the receiving plate, completing the entire paper stack transfer process.
[0038] 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.
