[0021] A guide bin 2 is fixedly arranged at the top of the machine body 1, the bottom of the guide bin 2 is communicated with the inner cavity of the machine body 1, and the top of the guide bin 2 is communicated with a feeding pipe, so that the raw pulp can enter the guide bin 2 through the external feeding pipe and then enter the machine body 1 through the guide bin 2. A guide assembly 3 is rotatably arranged in the guide bin 2, and the guide assembly 3 is used for guiding the raw materials into the beating section 101 or the refining section 102, so that the workers can control the raw materials to enter the beating section 101 or the refining section 102 through the guide assembly 3 according to the requirements, thereby avoiding that the raw materials containing coarse materials directly enter the refining section 102, preventing the refining disc from being damaged and affecting the quality of the subsequent paper production.
[0022] Further, the machine body 1 is in an inner cavity structure, a beating bin 4 is fixedly arranged in the machine body 1, the beating bin 4 is fixedly connected to the inner side wall of the beating section 101 through a connecting plate 401, a discharging pipe at the bottom of the beating bin 4 is communicated with the refining section 102, a fine material channel 5 is arranged between the beating section 101 and the beating bin 4, the bottom of the fine material channel 5 is also communicated with the refining section 102, and the feeding inlet at the top of the beating bin 4 and the feeding inlet at the top of the fine material channel 5 are both communicated with the guide bin 2, so that the raw materials in the guide bin 2 can enter the beating bin 4 or the fine material channel 5 after being guided by the guide assembly 3, and finally the raw materials in the beating bin 4 or the fine material channel 5 can enter the refining section 102 to perform the refining operation, thereby improving the refining efficiency.
[0023] The guide assembly 3 is described in detail below, so that the guiding effect of the guide assembly 3 is more clear.
[0024] The guide assembly 3 comprises a guide plate 301, one side of the guide plate 301 is rotatably connected to the inner side wall of the guide bin 2, as shown in the figure, Figure 2 The rotating connection position of the guide assembly 3 is opposite to the position between the feeding inlet at the top of the beating bin 4 and the feeding inlet at the top of the fine material channel 5, when the guide assembly 3 rotates to the left side or the right side, the movable end of the guide assembly 3 abuts against the left side wall or the right side wall of the guide bin 2, so as to shield the feeding inlet of the beating bin 4 or the fine material channel 5 on the corresponding side, and the guide assembly 3 itself is in an inclined state, thereby guiding the raw materials into the beating bin 4 or the fine material channel 5.
[0025] A locking plate 302 is fixedly connected to the movable end of the guide plate 301. The locking plate 302 has an equilateral trapezoidal structure so that when the guide plate 301 rotates to a side wall close to the guide chamber 2, the side of the locking plate 302 will abut against the side wall of the guide chamber 2, preventing the guide assembly 3 from continuing to slide down and thus locking the guide assembly 3 in place to avoid shaking. It should be noted that a handle for controlling the rotation of the guide assembly 3 is rotatably connected to the outer wall of the guide chamber 2, making it convenient for operators to control the orientation of the guide assembly 3.
[0026] In this embodiment, the pulping chamber 4 is equipped with a pulping mechanism 6 to crush and disperse coarse raw materials, facilitating subsequent grinding operations. A solenoid valve 7 is installed in the discharge pipe at the bottom of the pulping chamber 4, allowing operators to control the timing of raw material entry into the grinding section 102. This prevents raw materials from entering the grinding section 102 before pulping is complete, enabling staged pulping and grinding operations and improving grinding efficiency.
[0027] The working principle and usage process of this utility model are as follows: First, before introducing the raw slurry, check whether there are large materials in the raw slurry. If so, rotate the guide component 3 to the desired position. Figure 2 As shown in the diagram, the raw material is then introduced into the guide chamber 2 through the feed pipe. When the raw material falls, it will be guided into the pulping chamber 4 by the guide component 3, so that the pulping operation is performed first. After the pulping is completed, the solenoid valve 7 can be opened to allow the raw material to enter the refining section 102 for refining operation. Finally, the pulp is produced from the pulp outlet section 103.
[0028] When there are no coarse materials in the raw pulp, the guide assembly 3 can be rotated to abut against the left side wall of the guide chamber 2. At this time, the raw pulp will flow directly to the grinding section 102 through the fine material channel 5 for grinding operation, thereby improving the grinding efficiency.
