[0002] Cardboard can be used to make paper products such as cardboard boxes. However, during production, the cardboard needs to be cut into the required size according to production needs. After the cardboard is cut, a cardboard production splicing device is needed to splice the cardboard, thereby reducing the difficulty and large workload of manually splicing and stacking the cardboard by workers.

[0003] However, due to the poor adjustment and limiting capabilities of the paper splicing device in the existing paperboard production technology, it is not convenient to adjust the splicing limit distance of the splicing device according to the needs of use during actual use. This makes it inconvenient to perform splicing operations on paperboards of different sizes. The large distance affects the neatness of the splicing and stacking and reduces the efficiency of splicing. Utility Model Content

[0023] 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.

[0024] Please see Figures 1-4 This utility model provides a technical solution: a paperboard production paper receiving device, including a paper receiving platform 1, an L-shaped support plate 2 fixedly installed on one side of the paper receiving platform 1, and an adjustment limiting mechanism 3 provided at the top of the paper receiving platform 1;

[0025] The adjusting limit mechanism 3 includes electric push rods 301. Two electric push rods 301 are fixedly installed in the middle of the L-shaped support plate 2. A push rod 302 is fixedly installed at the output end of the electric push rod 301. A support limit plate 303 is fixedly installed on the side of the push rod 302 away from the electric push rod 301. A first limit groove 304 is opened on the side of the support limit plate 303 away from the push rod 302. A drive motor 305 is fixedly installed on one side of the support limit plate 303. The output shaft of the drive motor 305 is fixedly connected to a double-acting screw 306 through a coupling. The double-acting screw 306 extends into the interior of the first limit groove 304. A connecting bearing seat 307 is fixedly installed on the inner wall of the first limit groove 304 away from the drive motor 305. The end of the double-acting screw 306 away from the drive motor 305 is fixedly connected to the interior of the connecting bearing seat 307. Two movable parts are threadedly connected to the outer end of the double-acting screw 306. The screw block 308 and the supporting limiting plate 303 have a second limiting groove 309 located below the first limiting groove 304 on one side. A guide slide rod 310 is fixedly installed inside the second limiting groove 309. Two supporting slide blocks 311 are sleeved on the outer end of the guide slide rod 310. A limiting adjustment plate 312 is fixedly installed on one side of the moving screw block 308 and the supporting slide block 311. When the electric push rod 301 starts working, its output end extends to push the push rod 302, thereby driving the supporting limiting plate 303 to move. The drive motor 305 starts, and its output shaft drives the bidirectional lead screw 306 to rotate under the support of the connecting bearing seat 307. Since the threads at both ends of the bidirectional lead screw 306 rotate in opposite directions, the two moving screw blocks 308 will move towards or away from each other along the bidirectional lead screw 306 under the action of thread transmission. At the same time, the moving screw blocks 308 drive the limiting adjustment plate 312 to move.

[0026] The L-shaped support plate 2 and the top of the paper receiving platform 1 are provided with a support groove 4. The bottom end of the support limiting plate 303 is fixedly installed with a support slide rod 5. The support slide rod 5 is movably connected inside the support groove 4. The four corners of the bottom end of the paper receiving platform 1 are fixedly installed with hydraulic push rods 6. The bottom end of the hydraulic push rod 6 is installed with a hydraulic cylinder 7. The output end of the hydraulic cylinder 7 is fixedly installed with a hydraulic push rod 6. The middle part of the hydraulic cylinder 7 is fixedly installed with a reinforcing support rod 8. The bottom end of the reinforcing support rod 8 is fixedly installed with a load-bearing support base plate 9. The four corners of the bottom end of the load-bearing support base plate 9 are fixedly installed with support feet 10. The bottom end of the support feet 10 is fixedly installed with anti-slip pads 11. When the hydraulic cylinder 7 is working, the output end of the hydraulic cylinder 7 extends and retracts, driving the hydraulic push rod 6 to move, thereby realizing the raising and lowering of the height of the paper receiving platform 1.

[0027] Working Principle: When the paper splicing device is needed for paperboard production, it is first placed stably in the required position using support feet 10 and anti-slip pads 11. Then, an external power supply is connected to power the various electrical components and to the external control system. When the cut paperboard needs splicing, the adjustment limit mechanism 3 is activated via the external control system according to the paperboard size. The electric push rod 301 starts working, its output end extends to push the push rod 302, which in turn drives the support limit plate 303 to slide along the support slide 4. Guided by the support slide rod 5, the support limit plate 303 is adjusted to a suitable base position, initially determining the splicing limit range. Next, the drive motor 305 starts, its output shaft driving the bidirectional lead screw 306 to rotate under the support of the connecting bearing seat 307. Since the threads at both ends of the bidirectional lead screw 306 rotate in opposite directions, the two moving screw blocks 308 will move along the bidirectional lead screw 306 under the action of thread transmission. 06. The two limit adjustment plates 312 move towards or away from each other. At the same time, the moving screw block 308 drives the limit adjustment plate 312 to move. The guide slide rod 310 cooperates with the support slider 311 to ensure that the limit adjustment plate 312 remains stable during the movement. This allows for precise fine-tuning of the distance between the two limit adjustment plates 312 to adapt to the current size of the cardboard and complete the adjustment of the splicing limit distance. At this time, the cut cardboard is transported to the splicing platform 1. Under the limiting action of the limit adjustment plate 312 and the support limit plate 303, the cardboard can be neatly stacked. If the operator needs to adjust the height of the splicing platform 1, the hydraulic cylinder 7 can be controlled by the external control system. The output end of the hydraulic cylinder 7 extends and retracts, driving the hydraulic push rod 6 to move, thereby realizing the lifting and lowering of the height of the splicing platform 1. During the lifting and lowering process, the reinforcement support rod 8 ensures the stability of the device structure and prevents shaking. Throughout the splicing process, the device completes the cardboard splicing operation efficiently and neatly by flexibly adjusting the limit and height functions.

Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model do not depart from the essence and scope of the technical solution of this utility model.
