Description

Technical Field

[0001] This utility model relates to the field of papermaking equipment technology, specifically to a pulping device for manufacturing high-permeability CTP plate liner paper. Background Technology

[0002] In the manufacturing process of high-permeability CTP plate liner paper, traditional pulping equipment is difficult to meet the special requirements of this type of liner paper for fiber treatment. Existing pulping equipment has insufficient pulping precision and cannot fully refine and evenly disperse the fibers, resulting in uneven air permeability of the liner paper and affecting the performance of the CTP plate. Traditional equipment is difficult to precisely control the degree of fiber cutting and buffing, making it difficult to achieve an ideal balance between fiber bonding force and air permeability, thus affecting the overall performance of the liner paper. Utility Model Content

[0003] The purpose of this invention is to provide a high-permeability CTP plate liner paper manufacturing pulping device to solve the technical problems of traditional pulping equipment being unable to fully refine and uniformly disperse fibers, and having difficulty in accurately controlling the degree of fiber cutting and buffing.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A pulping device for manufacturing high-permeability CTP plate liner paper includes a pulping tank. A base plate is fixedly connected to the bottom end of the pulping tank. A stepper motor is fixedly connected to the bottom end of the pulping tank via a bracket. A rotating rod is fixedly connected to the output end of the stepper motor. The rotating rod is rotatably connected to the base plate and the pulping tank via bearings. A rotating grinding disc is fixedly connected to the bottom wall of the rotating rod. Several first grinding teeth are fixedly connected to the upper end of the rotating grinding disc. An external threaded sleeve is rotatably connected to the upper wall of the rotating rod via bearings. A fixed grinding disc is provided outside the external threaded sleeve. A threaded hole is opened through the middle of the fixed grinding disc. The threaded hole is threaded onto the external threaded sleeve. A feed port is opened through one side of the fixed grinding disc. Several second grinding teeth are fixedly connected to the lower end of the fixed grinding disc. A pusher is fixedly connected to one side of the upper end of the fixed grinding disc.

[0006] As a preferred embodiment of this utility model, a feed pipe with internal threaded fan blades is fixedly connected to the upper end of the feed inlet.

[0007] As a preferred embodiment of this utility model, the first grinding plate teeth and the second grinding plate teeth are arranged in a circular array on the rotating grinding disc and the fixed grinding disc, respectively, and the middle part of the first grinding plate teeth and the second grinding plate teeth is smaller than the edge.

[0008] As a preferred embodiment of this utility model, a flow channel is fixedly connected to one side of the grinding tank, and a comb roller arranged symmetrically is fixedly connected inside the flow channel. An inclined comb plate is fixedly connected to the outside of the comb roller, and the comb plates of adjacent comb rollers are inclined in opposite directions.

[0009] As a preferred embodiment of this utility model, a flow channel is fixedly connected to one side of the grinding tank, and a comb roller arranged symmetrically is fixedly connected inside the flow channel. An inclined comb plate is fixedly connected to the outside of the comb roller, and the comb plates of adjacent comb rollers are inclined in opposite directions.

[0010] Compared with existing technologies, the beneficial effects of this utility model of a high-permeability CTP plate liner paper manufacturing pulping device are as follows: It adopts a double-disc grinding structure with a unique toothed structure. The tooth spacing and depth are smaller near the center of the grinding disc, used for initial crushing and directional guidance of the material; the tooth spacing and depth gradually increase further away from the center to enhance the refining and dispersion of fibers. Simultaneously, the external threaded tube and threaded hole facilitate adjustment of the gap between the grinding discs, meeting the fiber pulping requirements at different stages. The inclined comb teeth on the surface of the comb rollers, with adjacent comb rollers having opposite inclination directions, allow the fibers to be further dispersed and oriented as they pass through the comb rollers, thus improving the uniformity of the liner paper's permeability.

[0021] See Figure 1-5 This utility model provides a high-permeability CTP plate backing paper manufacturing pulping device, including a pulping tank 1, a base plate 2 fixedly connected to the bottom end of the pulping tank 1, a stepper motor 3 fixedly connected to the bottom end of the pulping tank 1 via a bracket, a rotating rod 4 fixedly connected to the output end of the stepper motor 3, the rotating rod 4 being rotatably connected to the base plate 2 and the pulping tank 1 via a bearing, and a rotating grinding disc 5 fixedly connected to the bottom wall of the rotating rod 4, a plurality of first grinding teeth 6 fixedly connected to the upper end of the rotating grinding disc 5, and an external threaded sleeve 7 rotatably connected to the upper wall of the rotating rod 4 via a bearing, a fixed grinding disc 8 being provided outside the external threaded sleeve 7, and a threaded hole 9 being threaded through the middle of the fixed grinding disc 8, the threaded hole 9 being threadedly connected to the external threaded sleeve 7.

[0022] A feed inlet 10 is opened through one side of the fixed grinding disc 8. Several second grinding disc teeth 12 are fixedly connected to the lower end of the fixed grinding disc 8. A pusher 13 is fixedly connected to one side of the upper end of the fixed grinding disc 8. A feed pipe 11 with internal threaded fan blades is fixedly connected to the upper end of the feed inlet 10. The first grinding disc teeth 6 and the second grinding disc teeth 12 are arranged in a circular array on the rotating grinding disc 5 and the fixed grinding disc 8 respectively, and the middle of the first grinding disc teeth 6 and the second grinding disc teeth 12 is smaller than the edge.

[0023] A flow channel 14 is fixedly connected to one side of the grinding tank 1. A comb roller 15 arranged symmetrically is fixedly connected inside the flow channel 14. An inclined comb plate 16 is fixedly connected to the outside of the comb roller 15. The comb plates 16 of adjacent comb rollers 15 are inclined in opposite directions. A support foot arranged in a circular array is fixedly connected to the lower edge of the grinding tank 1.

[0024] When grinding is required, push plate 13 is pushed according to the grinding situation. Push plate 13 drives fixed grinding plate 8 under force. Fixed grinding plate 8 is adjusted in height under the action of threaded hole 9 and external threaded sleeve 7, thereby adjusting the distance between fixed grinding plate 8 and rotating grinding plate 5. Fixed grinding plate 8 and outer wall of grinding tank 1 are limited and fastened by external bracket. At this time, raw material is put into feed pipe 11. The feed speed is increased by the threaded fan blade inside feed pipe 11. Raw material enters between fixed grinding plate 8 and rotating grinding plate 5 through feed pipe 11 and feed port 10.

[0025] When the external power supply starts the stepper motor 3, the output of the stepper motor 3 drives the rotating rod 4 to rotate. The rotating rod 4 then drives the rotating grinding disc 5 to rotate through the bearing. At this time, the first grinding disc tooth 6 and the second grinding disc tooth 12 between the rotating grinding disc 5 and the fixed grinding disc 8 are used to grind the material quickly. The grinding disc surfaces of the fixed grinding disc 8 and the rotating grinding disc 5 are equipped with a unique tooth structure. The first grinding disc tooth 6 and the second grinding disc tooth 12 adopt a variable tooth pitch and variable tooth depth design. The tooth pitch is smaller and the tooth depth is shallower near the center of the grinding disc, which is used for preliminary crushing and directional guidance of the material.

[0026] The tooth spacing and tooth depth gradually increase away from the center area to enhance the refining and dispersion of the fibers. After pulping, the pulp flows into the inlet trough 14 and passes through the comb teeth 16 on the comb roller 15 as the pulp flows. Through the mutually inclined comb teeth 16, the fibers are further dispersed and oriented by the combing action of the comb teeth 16 when passing through the comb roller 15. This helps to improve the air permeability and uniformity of the liner paper and facilitates its later use.

[0027] The foregoing has shown and described the basic principles of the present invention. The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. The above embodiments and descriptions in the specification are only illustrative of the principles of the present invention. Any modifications, equivalent substitutions, and improvements made within the scope of the present invention without departing from the scope of the present invention should be included within the protection scope of the present invention.
