Description

Technical Field

[0001] The utility model relates to papermaking equipment, in particular to a bamboo pulp paper pulverizer. Background Art

[0002] Bamboo pulp paper made from virgin fibers extracted from naturally grown bamboo not only retains the excellent air permeability and rapid water absorption characteristics of bamboo itself, but also plays a role in improving the overall durability of paper. This kind of paper performs well in practical applications, does not produce powder or debris, ensures convenience and cleanliness in use, and is considered to be a high-quality paper material.

[0003] The production of bamboo pulp paper relies on the production of virgin bamboo on the one hand, and on the processing and production of waste paper on the other hand. The processing and production of waste paper requires the waste paper to be crushed and then processed. The recycling of paper effectively reduces the dependence on new raw materials and plays a positive role in protecting and saving bamboo resources.

[0004] However, the existing high-density shredders cut the paper into extremely fine paper powder during the recycling and shredding process of bamboo pulp paper, which destroys the fibers of the bamboo pulp paper and makes the paper powder possibly unrecyclable. Utility Model Content

[0034] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0035] Example:

[0036] See also Figure 1-Figure 3A bamboo pulp paper pulverizer includes a pulverizing chamber 1, a screen 2, a main shaft 3, a motor 4, a knife holder 5 and a blade 6. The top of the pulverizing chamber 1 is a material inlet, and the bottom is a material outlet. A screen 2 is arranged on the material outlet at the bottom of the pulverizing chamber 1, and the screen 2 and the pulverizing chamber 1 are detachably connected.

[0037] The two ends of the main shaft 3 are rotatably connected to the two ends of the grinding chamber 1 respectively, and the main shaft 3 is located in the grinding chamber 1, one end of the main shaft 3 passes through one end of the grinding chamber 1, and this end of the main shaft 3 is dynamically connected to the output shaft of the motor 4. Generally, a belt mechanism is used to realize the dynamic connection between the main shaft 3 and the motor 4.

[0038] A tool holder 5 is mounted on the main shaft 3 . The rotation of the main shaft 3 drives the tool holder 5 to rotate together. A plurality of blades 6 are mounted on the tool holder 5 .

[0039] The blade 6 is a long strip structure, the length direction of the blade 6 is consistent with the axial direction of the main shaft 3, and all the blades 6 are evenly distributed around the main shaft 3. At the same time, one side of the blade edge of the blade 6 is in a direction away from the tool holder 5.

[0040] The screen 2 is an arc-shaped structure, and the distance between the screen 2 and the main shaft 3 is greater than the radius of the blade 6 when it rotates with the main shaft 3.

[0041] In this embodiment, waste paper to be crushed is added into the crushing chamber 1 through the feed port at the top of the crushing chamber 1, a discharge port is set at the bottom of the crushing chamber 1, and a screen 2 is set on the discharge port. By selecting the aperture of the screen 2, the particle size of the waste paper during output is controlled, thereby avoiding the destruction of bamboo pulp paper fibers.

[0042] In addition, by arranging the blade 6 transversely on the blade holder 5 and setting the length direction of the blade 6 to be the same as the axial direction of the main shaft 3, the degree of damage to the bamboo pulp paper fibers by the blade 6 can be reduced, and at the same time, the waste paper can be effectively crushed.

[0043] In one specific embodiment:

[0044] All blades 6 are evenly distributed around the main shaft 3. There is a distance between the plane where one side of the blade 6 is located and the axis of the main shaft 3. When the main shaft 3 drives the blade 6 to rotate, the cutting edge of the blade 6 will crush the waste paper at a certain angle, thereby improving the efficiency of crushing the waste paper without increasing the probability of damaging the bamboo pulp paper fibers.

[0045] In another specific embodiment:

[0046] A plurality of tool rests 5 are arranged on the main shaft 3 , and all the tool rests 5 are distributed along the axial direction of the main shaft 3 , and the projections of all the tool rests 5 on the vertical plane can completely overlap.

[0047] Each blade 6 is connected to a plurality of blade holders 5 .

[0048] In this embodiment, a plurality of tool holders 5 are arranged between the main shaft 3 and the blade 6 to ensure the strength of the blade 6 and avoid the blade 6 from breaking.

[0049] Preferably, the tool holder 5 includes a connecting portion and a mounting portion, wherein the connecting portion is an equilateral triangle structure, and a through hole is provided in the middle of the connecting portion, and the spindle 3 passes through the through hole and is fixedly connected to the connecting portion.

[0050] A mounting portion is provided at each of the three corners of the connecting portion, and a blade 6 is provided at each side of the three mounting portions on the same connecting portion. One side of the same blade 6 is connected to the mounting portions on the three connecting portions.

[0051] By setting the connection part of the tool holder 5 as a triangular structure, in addition to improving the strength of the tool holder 5, the space occupied by the tool holder 5 can also be reduced. The blade 6 is installed on one side of the installation part, and the impact force borne by the blade 6 can be dispersed to the three installation parts, thereby preventing the blade 6 from being damaged.

[0052] In another specific embodiment:

[0053] The pulverizing chamber 1 is arranged on a frame 7. By arranging the frame 7, the discharge port at the bottom of the pulverizing chamber 1 is raised to a certain height so as to collect the pulverized waste paper.

[0054] A material guide trough is provided on the top of the pulverizing chamber 1 , and the material guide trough is located on the material inlet. The purpose of providing the material guide trough is to facilitate adding waste paper to be shredded into the pulverizing chamber 1 .

[0055] An observation window is provided on one side of the pulverizing chamber 1 , and an openable cover plate 8 is provided on the observation window. When the cover plate 8 is opened, the degree of pulverization of waste paper in the pulverizing chamber 1 and the remaining amount of waste paper can be observed through the observation window.

[0056] The above-mentioned embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
