[0023] The following is combined with Figure 1 -Attached Figure 3 This application is described in further detail.

[0024] The present application discloses a grinding device for paper towel processing. Figure 1-Figure 3 A paper towel processing grinding device includes a box body 1, a material feed port 2 is installed on the top of the box body 1, a material discharge port 3 is installed on the outer wall, a fixed grinding disc 9 is fixed inside the box body 1, a fixed plate 11 is fixed inside the box body 1, and a height-adjustable lifting plate 4 is further installed below the fixed plate 11 inside the box body 1. A first motor 5 is installed on the lifting plate 4, and the output end of the first motor 5 passes through the fixed plate 11 and is fixed with a connecting rod 6. The top end of the connecting rod 6 is located inside the fixed grinding disc 9 and is fixed with a grinding body 7 by bolts;

[0025] It also includes a height adjustment component, which is used to adjust the distance between the grinding body 7 and the fixed grinding disc 9. The height adjustment component is connected to the lifting plate 4. When in use, first, the paper towel raw material can be put into the box body 1 from the feed port 2, and then the first motor 5 is started. The first motor 5 drives the connecting rod 6 and the grinding body 7 installed on the top of the connecting rod 6 to rotate. During the grinding process, the first motor 5 drives the grinding body 7 to rotate at a high speed, forming a strong shear force and friction force between the grinding body 7 and the fixed grinding disc 9, and finely grinding the raw material. The ground pulp passes through the gap between the fixed grinding disc 9 and the grinding body 7, continues to flow downward, and is discharged from the discharge port 3, completing the preliminary grinding process of paper towel processing;

[0026] When grinding pulp of different particle sizes, the lifting plate 4 can adjust the distance between the grinding body 7 and the fixed grinding disc 9 according to the different particle sizes in the pulp under the action of the height adjustment component. This design cleverly solves the limitation of the existing pulping machine that the grinding disc spacing is fixed and cannot adapt to pulp of different particle sizes. Since the distance between the grinding body 7 and the fixed grinding disc 9 is adjustable, the device can flexibly cope with pulp raw materials of different particle sizes, ensuring that the grinding effect is always maintained in the best state, thereby improving the quality and production efficiency of paper towel products.

[0027] Reference Figure 1 、 Figure 2 and Figure 3The height adjustment component also includes a bidirectional screw 13 rotatably connected to the inside of the box body 1. A second motor 14 is installed on the outer wall of the box body 1 to drive the bidirectional screw 13 to rotate. Two movable plates 15 are installed on the outer wall of the bidirectional screw 13 through a thread. The bottom of the lifting plate 4 is connected to a pair of connecting plates 16 through a rotating shaft. The two pairs of connecting plates 16 are respectively connected to the two movable plates 15 through a rotating shaft; when in use, when it is necessary to adjust the distance between the grinding body 7 and the fixed grinding disc 9 to adapt to pulp of different particle sizes, the user can achieve this purpose by starting the second motor 14. The second motor 14 drives the bidirectional screw 13 to rotate. Since the outer wall of the bidirectional screw 13 is connected to the two movable plates 15 through a threaded connection, as the bidirectional screw 13 rotates, the two movable plates 15 will move relative to or oppositely along the axial direction of the bidirectional screw 13;

[0028] This movement is transmitted to the lifting plate 4 through the connecting plate 16, so that the lifting plate 4 can move up and down inside the box 1. Since the lifting plate 4 is fixedly connected to the first motor 5 and the connecting rod 6, as the lifting plate 4 moves up and down, the connecting rod 6 and the grinding body 7 installed on the top thereof will also adjust the distance between them and the fixed grinding disc 9 accordingly. This design is not only simple in structure, but also has a smooth and reliable adjustment process, ensuring the accuracy and stability of the spacing adjustment during the grinding process.

[0029] Reference Figure 2 and Figure 3 Four fixing tubes 18 are fixed at the bottom ends of the lifting plate 4 at the four corners inside the box body 1. When in use, when the lifting plate 4 moves to the lowest position, these fixing tubes 18 not only provide additional support for the lifting plate 4, but also limit its lowest position of descent, ensuring the safe operation of the equipment.

[0030] Reference Figure 2 and Figure 3 , the four corners of the bottom end of the lifting plate 4 are fixed with guide rods 17 for inserting into the fixed tube 18, and the guide rods 17 have the freedom to move along the height of the fixed tube 18; the coordinated use of the guide rods 17 and the fixed tube 18 further enhances the stability and guidance of the lifting plate 4 during movement. The guide rods 17 slide inside the fixed tube 18, which not only ensures that the lifting plate 4 can move up and down along the predetermined trajectory, but also avoids the lifting plate 4 from deflecting or shaking during movement, thereby ensuring the accuracy of the spacing adjustment between the grinding body 7 and the fixed grinding disc 9.

[0031] Reference Figure 2 A plurality of heat dissipation holes 10 are provided on the upper portion of the lifting plate 4 and below the first motor 5 , so as to facilitate heat dissipation of the first motor 5 .

[0032] Reference Figure 1The outer wall of the box body 1 is also provided with a perspective window 19, which can facilitate the staff to observe and monitor the operating status of the grinding device, and promptly discover and deal with possible abnormal situations.

[0033] Reference Figure 2 An inclined plate 12 is fixed on the fixed plate 11, and the connecting rod 6 passes through the inclined plate 12; so that the ground pulp can slide smoothly along the inclined plate 12, avoiding the accumulation and blockage of the pulp during the grinding process.

[0034] Reference Figure 2 The top surface of the grinding body 7 is provided with an arc-shaped groove 8, which allows the pulp to slide along the arc-shaped groove 8 and prevents the unground pulp from accumulating on the top surface of the grinding body 7.

[0035] The implementation principle of the grinding device for paper towel processing in the embodiment of the present application is as follows: when in use, first, the paper towel raw material can be put into the box body 1 from the feed port 2, and then the first motor 5 is started. The first motor 5 drives the connecting rod 6 and the grinding body 7 installed on the top of the connecting rod 6 to rotate. During the grinding process, the first motor 5 drives the grinding body 7 to rotate at a high speed, forming a strong shear force and friction force between the grinding body 7 and the fixed grinding disc 9, and finely grinding the raw material. The ground pulp passes through the gap between the fixed grinding disc 9 and the grinding body 7, continues to flow downward, and is discharged from the discharge port 3, completing the preliminary grinding process of paper towel processing;

[0036] When grinding pulp of different particle sizes, when it is necessary to adjust the distance between the grinding body 7 and the fixed grinding plate 9 to adapt to pulp of different particle sizes, the user can achieve this purpose by starting the second motor 14. The second motor 14 drives the bidirectional screw 13 to rotate. Since the outer wall of the bidirectional screw 13 is connected to the two movable plates 15 through threads, as the bidirectional screw 13 rotates, the two movable plates 15 will move relative to or in opposite directions along the axial direction of the bidirectional screw 13;

[0037] This movement is transmitted to the lifting plate 4 through the connecting plate 16, so that the lifting plate 4 can move up and down inside the box 1. Since the lifting plate 4 is fixedly connected to the first motor 5 and the connecting rod 6, as the lifting plate 4 moves up and down, the connecting rod 6 and the grinding body 7 installed on the top of the connecting rod 6 will also adjust the distance between the fixed grinding disc 9 accordingly. This design is not only simple in structure, but also smooth and reliable in the adjustment process, ensuring the accuracy and stability of the distance adjustment during the grinding process.

[0038] This allows staff to adjust the distance between the grinding body 7 and the fixed grinding disc 9 according to the size of the pulp particles. This design cleverly solves the limitation of the existing pulping machine in which the grinding disc spacing is fixed and cannot adapt to pulps of different particle sizes. Since the distance between the grinding body 7 and the fixed grinding disc 9 is adjustable, the device can flexibly cope with pulp raw materials of different particle sizes, ensuring that the grinding effect is always maintained in the best state, thereby improving the quality and production efficiency of paper towel products.
