Description

Technical Field

[0001] The utility model relates to the technical field of cardboard production, in particular to a white cardboard raw material pulping machine. Background Art

[0002] The main raw materials for white cardboard include waste paper and wood pulp. During the production process, the raw materials need to be sorted, screened, and cleaned to ensure that their quality meets production requirements. Since the raw materials often exist in lumps or flakes, using them directly in papermaking will affect the uniformity of the pulp and the quality of the paper. Therefore, a pulper can break these raw materials into smaller particles or fibers for easier processing in subsequent steps.

[0003] Existing Chinese patent publication number CN209555648U discloses a high-efficiency pulper for papermaking. It includes a pulper body, a rotary auger mounted within the body, the upper end of the rotary auger connected to a motor via a coupling, the motor fixed above the pulper, and the lower end of the rotary auger connected to the lower portion of the pulper via a support frame. The connection between the support frame and the rotary auger is fixed with a bearing. A feed inlet and a water inlet are located above the pulper. This significantly reduces pulping time, improves pulping efficiency, increases production, reduces energy consumption, and is more energy-efficient and environmentally friendly.

[0004] Based on the above situation, the inventors believe that, since the raw material feeding is often completed through a single feeding port, the mixing efficiency of the raw material and water is poor, and sometimes blockage is prone to occur. Therefore, in order to improve this situation, the inventors have proposed an improved pulper. Utility Model Content

DETAILED DESCRIPTION

[0034] The following will clearly and completely describe the technical solutions of the present invention in conjunction with specific embodiments. Obviously, the embodiments described are only some of the embodiments of the present invention, and not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0035] The embodiment of the present utility model specifically provides a white cardboard raw material pulping machine, please refer to the figure, which includes a pulping tank and a material leveling component.

[0036] Among them, the top surface of the pulping tank is coaxially opened with a feed port, and the raw materials are fed into the pulping tank through the feed port. A crushing component is set in the feed port, and a base is fixed at the bottom of the pulping tank so that it can be placed in a suitable processing position through the base. The pulping tank and the crushing component are both existing mature components. The raw materials fed into the pulping tank are crushed and mixed by the crushing component;

[0037] Among them, the material leveling assembly includes an outer retaining ring, an inner retaining ring, a feeding assembly and a driving assembly. The outer retaining ring is fixedly connected to the inner wall of the feed port, and the outer retaining ring and the inner retaining ring are fixed to each other. The feeding assembly is installed on the outer retaining ring, and the output end of the driving assembly is connected to the feeding assembly to drive the feeding assembly to move through the driving assembly.

[0038] Specifically, please refer to Figures , , and . The outer retaining ring includes a top tube and a bottom tube arranged below the top tube. The adjacent surfaces of the top tube and the bottom tube are spaced apart to form a slide groove. The outer wall of the bottom tube is fixedly fitted with the feed port, so that the top tube and the bottom tube cooperate to form a retaining ring at the feed port when feeding the raw materials, which facilitates the smooth delivery of the raw materials into the feed port and is put into the pulping tank through the feed port.

[0039] Among them, the inner retaining ring includes a support plate and an inner tube fixedly connected to the support plate at the bottom end. The crushing assembly is fixedly installed on the support plate, so that the crushing assembly can be firmly installed to crush and mix the raw materials. The top of the inner tube is consistent with the height of the top tube. Through the mutual cooperation between the inner tube and the top tube and the bottom tube, the raw materials can be stably dropped into the feed port for feeding under the space limitation between the inner tube and the top tube and the bottom tube.

[0040] Specifically, a first support rod and a second support rod are fixed to the outside of the inner tube and the support plate respectively. The inner tube and the support plate are fixed to the top tube and the bottom tube respectively through the first support rod and the second support rod, so that the support plate and the inner tube can maintain a stable installation to improve the stability and life of use.

[0041] During implementation, the top pipe, bottom pipe, support plate and inner pipe are all coaxial with the feed port, so that the raw materials can be stably fed into the feed port, which is similar to the traditional feed pipe with a smaller feed area. The feed port can improve the convenience of feeding, improve the dispersion of raw materials, and reduce the stacking of raw materials and slow water absorption rate.

[0042] Further, please refer to Figures and Figures. The feeding assembly includes a turntable whose upper and lower surfaces are in rotational contact with the chute and a receiving plate fixed to the turntable on the outside. The turntable is an overall ring-shaped structure to facilitate the rotation convenience in the chute.

[0043] Among them, the receiving plate is located within the projection range directly above the feed port, so that when the raw materials are fed into the feed port through the conveying equipment, the raw materials can be received by the receiving plate, and the received raw materials are then sent to other areas above the feed port through rotation and continue to be fed downward, thereby avoiding the raw materials being fed at a single position on the feed port and reducing stacking.

[0044] Specifically, a first baffle and a second baffle are fixedly provided on the inner wall of the top tube, and the bottom end of the second baffle is in sliding contact with the surface of the receiving plate. The first baffle and the second baffle are set at different heights, and the first baffle and the second baffle are spaced apart along the circumferential direction of the top tube. The height of the bottom end of the first baffle is consistent with the height of the top end of the second baffle, so that when the receiving plate receives the loaded raw materials, the rotating column of the turntable can drive the receiving plate to move closer to the first baffle, and the raw materials on the upper part of the receiving plate are blocked and pushed into the feed port through the first baffle, so that the remaining raw materials on the receiving plate continue to be transported, and are blocked and scraped off by the second baffle, so that the raw materials on the receiving plate can fall into different positions in the feed port, so as to reduce the stacking caused by a single feeding position of the raw materials.

[0045] Among them, a limit ring protruding upward is fixedly provided on the surface of the turntable, and the inner wall of the limit ring is in sliding contact with the top pipe, so that the turntable can rotate stably in the slide groove.

[0046] Further, please refer to the figure. There are teeth grooves on the outside of the turntable. The driving assembly includes a gear meshing with the teeth grooves on the outside, a motor fixedly connected to the gear at the output end, and a mounting bracket fixed to the pulping tank at the bottom end. The outside of the motor is fixedly connected to the mounting bracket, and the gears are driven to rotate synchronously through the rotation of the motor, so that force is applied to the turntable through the gears, so that the turntable can maintain synchronous rotation, thereby driving the receiving plate to move to receive and discharge materials, and by allowing the receiving plate to reset after displacement for one circle to continue receiving materials, the dispersed feeding of the raw materials is completed, thereby improving the pulping efficiency.

[0047] The control method of the present invention is to manually start and stop the switch. The wiring diagram of the power element and the provision of power supply are common knowledge in the field. Moreover, the present invention is mainly used to protect mechanical devices. Therefore, the control method and wiring arrangement are not explained in detail in the present invention.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
