Description

Technical Field

[0001] The utility model relates to the technical field of paper processing equipment, in particular to a feeding mechanism for paper production. Background Art

[0002] In the paper production process, pulp feeding and uniform distribution are crucial links. Traditional pulp feeding methods are mostly manual or semi-automatic, relying on frequent manual operations, which is not only inefficient, but also easily causes uneven pulp distribution, thus affecting the quality of the finished paper. With the development of industrial automation, how to improve the automation level of pulp feeding and ensure the uniform distribution of pulp during the production process has become an important topic in the research and development of paper production equipment.

[0003] Traditional pulp feeding mechanisms mostly use simple gravity feeding or mechanical feeding methods. During the transportation process, pulp is prone to accumulate in a single place where it is poured. The uneven distribution of pulp leads to uneven distribution of pulp on the screen plate after it is unloaded, resulting in differences in thickness and density of the finished paper, affecting product quality. Utility Model Content

[0004] In order to solve the above problems, the utility model proposes a feeding mechanism for paper production, including a pulp screen plate, a feeding guide plate is arranged above the pulp screen plate, a conveying frame is slidably arranged above the feeding guide plate, a feeding hopper is fixed on the top of the conveying frame, an inclined frame passing through the feeding guide plate is fixed on the bottom of the conveying frame, a slide groove for the lateral movement of the inclined frame is opened on the conveying frame, a connecting block is fixed to the side wall of the conveying frame, a servo motor is installed on the top of the feeding guide plate, a screw rod is connected to the output end of the servo motor, and the screw rod is connected to the connecting block; a connecting block is fixed to the opposite side wall of the conveying frame and the connecting block, a mounting plate is fixed to the connecting block and the side wall of the connecting block, a shaft rod is rotatably connected to the mounting plate, and a pressing cylinder is fixed to the outer side of the shaft rod.

[0005] Furthermore, a collecting plate is fixed on the inner wall of the conveying frame, an arc-shaped groove is opened in the middle of the collecting plate, a through groove is opened through the collecting plate below the arc-shaped groove, and the through groove is connected with the inside of the inclined frame.

[0006] Furthermore, a blocking rod is rotatably connected in the arc groove of the collecting plate. The blocking rod is formed by splicing and fixing a fan-shaped block and a trapezoidal block. The fan-shaped section of the blocking rod can block the through groove, while the trapezoidal section of the blocking rod cannot block the through groove. A rotating rod extending outside the conveying frame is fixed at one end of the blocking rod, and a stepping motor is connected to the other end of the rotating rod.

[0007] Furthermore, the inclined frame is arranged to be inclined relative to the pulp screen plate, and a plurality of material guide plates are fixed to the inner wall of the inclined frame.

[0008] Furthermore, a tooth plate is fixed on the top of the pulp screen plate, the shaft rod passes through the mounting plate and a spur gear is fixed on the outer side, and the spur gear is meshed with the tooth plate.

[0009] The beneficial effects of the utility model are as follows:

[0010] 1. The feeding mechanism ensures that the pulp can be evenly distributed on the screen plate through the combined design of the conveying frame, the guide plate and the inclined frame. Driven by the servo motor and the screw rod, the conveying frame moves smoothly along the feeding guide plate, so that the pulp is evenly coated on the screen plate during the movement. It effectively ensures the uniformity of the finished paper and improves the quality of the paper.

[0011] 2. Through the automatic control of servo motors, stepper motors and screw rods, the automatic transportation and distribution of pulp is realized, which greatly reduces the complexity and labor intensity of manual operation. Workers only need to simply operate the control system to achieve uniform feeding of pulp, which improves production efficiency and reduces labor costs.

[0012] 3. The feeding mechanism avoids the splashing and waste of pulp through the design of the inclined frame and guide plate, so that the pulp can be effectively used. At the same time, the automatic control reduces the human operation error and further reduces the waste of pulp. In addition, the uniform distribution of pulp reduces the scrap rate in the subsequent processing process and improves the overall production efficiency and economic benefits.

[0021] The utility model is further described below in conjunction with the accompanying drawings:

[0022] A feeding mechanism for paper production, such as Figure 1 and Figure 2 As shown, it includes a pulp screen plate 1, a feed guide plate 2 is arranged above the pulp screen plate 1, a conveying frame 3 is slidably arranged above the feed guide plate 2, a feed hopper 4 is fixed to the top of the conveying frame 3, an inclined frame 5 passing through the feed guide plate 2 is fixed to the bottom of the conveying frame 3, the inclined frame 5 is inclined relative to the pulp screen plate 1, and a plurality of guide plates 18 are fixed to the inner wall of the inclined frame 5; a slide groove for the inclined frame 5 to move horizontally is opened on the conveying frame 3, a connecting block 6 is fixed to the side wall of the conveying frame 3, and the top of the feed guide plate 2 is provided with a connecting block 6. A servo motor 7 is installed, and a screw rod 8 is connected to the output end of the servo motor 7, and the screw rod 8 is connected to the connecting block 6; a connecting block is fixed to the opposite side wall of the conveying frame 3 to the connecting block 6, and a mounting plate 9 is fixed to the connecting block 6 and the side wall of the connecting block, and a shaft rod 10 is rotatably connected to the mounting plate 9, and a pressing cylinder 11 is fixed to the outer side of the shaft rod 10; a tooth plate 20 is fixed to the top of the pulp screen plate 1, and the shaft rod 10 passes through the mounting plate 9 and a spur gear 19 is fixed to the outer side, and the spur gear 19 is meshed with the tooth plate 20.

[0023] like Figure 3 , Figure 4 and Figure 5As shown, in this embodiment, a collecting plate 12 is fixed to the inner wall of the conveying frame 3, and an arc-shaped groove 13 is opened in the middle of the collecting plate 12. A through groove is opened through the collecting plate 12 below the arc-shaped groove 13, and the through groove is connected with the inside of the inclined frame 5; a blocking rod 15 is rotatably connected in the arc-shaped groove 13 of the collecting plate 12, and the blocking rod 15 is formed by splicing and fixing a fan-shaped block and a trapezoidal block. The fan-shaped section of the blocking rod 15 can block the through groove, and the trapezoidal section of the blocking rod 15 cannot block the through groove. A rotating rod 16 extending to the outside of the conveying frame 3 is fixed to one end of the blocking rod 15, and a stepping motor 17 is connected to the other end of the rotating rod 16.

[0024] The working principle of the utility model is as follows:

[0025] The slurry is poured into the hopper 4. In the initial state, the fan-shaped segment of the blocking rod 15 blocks the through groove, so that the slurry accumulates on the collecting plate 12 to prevent the slurry from only being discharged from the pouring place while there is less slurry in other places. After the slurry is evenly filled on the collecting plate 12, the stepper motor 17 is started to rotate 180 degrees, so that the fan-shaped segment of the blocking rod 15 is separated from the through groove, and the slurry flows to the through groove through the gap between the blocking rod 15 and the arc groove 13, and falls evenly along the through groove.

[0026] The pulp falls onto the inclined frame 5 through the through groove, flows along the inclined surface of the inclined frame 5, and is guided by the guide plate 18 to prevent the pulp from falling directly on the pulp screen plate 1 and splashing. The guide plate 18 allows the pulp to flow evenly along the inner wall of the inclined frame 5 and the guide plate 18 to the pulp screen plate 1; the servo motor 7 is started to drive the screw rod 8 to rotate, so that the connecting block 6 connected to the screw rod 8 drives the conveying frame 3 to slide along the feeding guide plate 2 as a whole, and the inclined frame 5 moves together with the conveying frame 3 while evenly coating the pulp on the pulp screen plate 1; while the mounting plate 9 moves together with the connecting block 6, the spur gear 19 rolls on the tooth plate 20, thereby driving the shaft 10 and the pressing cylinder 11 to rotate, and the pulp seeps water on the pulp screen plate 1. The pressing action of the pressing cylinder 11 further removes the water, so that the fibers form a paper layer on the screen, and the pulp is evenly coated on the pulp screen plate 1, thereby improving the uniformity and quality of the paper layer.
