Description

Technical Field

[0001] The present invention relates to the technical field of paper fiber processing, in particular to a raw material crushing device for paper fiber processing. Background Art

[0002] Paper fiber is a fibrous material recycled from waste paper products. Its main purpose is to make recycled paper, thereby reducing the consumption of trees in the papermaking process and achieving the purpose of resource recycling. During the processing of paper fiber, professional equipment is usually needed to first break it into pieces of roughly the same size, and then further crush it to finally form the corresponding paper fiber.

[0003] When crushing raw materials, since the raw materials come from various forms of paper products, most of which are recycled from scrap stations, they are usually directly put into the crushing box and crushed by two sets of crushing rollers.

[0035] A support plate 10 for supporting the feed hopper 3 is fixedly welded to the bottom of the front of the crushing box 1. A second drive motor 8 is installed on the side of the crushing box 1. The output end of the second drive motor 8 is fixedly connected to the crushing roller 11.

A gear box 13 is installed on the outer surface of the first transmission gear 12. A support frame 52 is installed at the bottom of the crushing box 1, and the crusher 5 is installed at the bottom of the support frame 52.

[0036] The crusher 5 includes a conical crushing bin 51 and a plurality of crushing rollers 55 installed in a circular array inside the conical crushing bin 51. A first drive motor 53 is installed on the top of the support frame 52. A transmission belt 54 is installed between the first drive motor 53 and a group of crushing rollers 55. Second transmission gears 56 that mesh with each other in sequence are installed between the plurality of crushing rollers 55.

[0037] The pneumatic discharger 4 includes a discharge pipe 41 and a pneumatic conveying fan 44 installed at the end of the discharge pipe 41. The bottom end of the conical crushing bin 51 is installed in the middle of the discharge pipe 41. The other end of the discharge pipe 41 is installed with two groups of storage bags 42 for alternate discharge.

[0038] The end of the discharge pipe 41 is fixedly connected to an N-shaped connecting pipe 43, and a sliding sealing plate 45 is provided inside the N-shaped connecting pipe 43. An adjusting screw 46 is rotatably connected to one side of the sliding sealing plate 45, and the adjusting screw 46 is threadedly connected to the side wall of the N-shaped connecting pipe 43.

[0039] A clamping seat 47 is installed at the bottom of the N-shaped connecting pipe 43, and a detachable connecting seat 48 is installed on the top of the storage bag 42. A clamping strip 49 is fixedly welded to the top of the connecting seat 48, and the clamping strip 49 is movably clamped to the inner bottom of the clamping seat 47.

[0040] Working principle: In the initial state of the device, the pressure plate 6 is at the bottom of the crushing box 1, and the feed hopper 3 is at odds with the bottom of the support plate 10. When in use, by starting the second drive motor 8, the second drive motor 8 drives a group of crushing rollers 11 to rotate. At the same time, under the action of the two groups of first transmission gears 12, the two groups of crushing rollers 11 rotate synchronously toward the middle, so as to roll and crush the material. Then, the waste paper products to be crushed are placed into the feed hopper 3, and then the lifting hydraulic machine 2 is started, so that the lifting hydraulic machine 2 drives the pressure plate 6 to move upward, and at the same time, the traction cable 75 is driven to move upward through the connecting arm 72. At the same time, the bottom end of the traction cable 75 pulls the positioning slider 76 to slide upward along the limit slide rail 73, so that the feed hopper 3 loaded with raw materials moves upward. When the pressure plate 6 moves above the feed port, the feed hopper 3 just moves to the feed port position, and at the same time, the seesaw 95 moves to the inner top of the limit bar 92, and then the pressure plate 6 continues to move upward for a distance. At this time, as the feed hopper 3 moves upward, the seesaw 95 rotates with the fixed shaft 94 as the axis, causing the flip baffle 91 to flip inward. At this time, the raw materials on the upper surface of the flip baffle 91 are pushed into the inside of the feed port, completing the loading. Then the output end of the lifting hydraulic press 2 extends, driving the pressure plate 6 to move downward, pressing down the material inside the crushing box 1, making it close to the crushing roller 11, which is more conducive to the contact between the crushing roller 11 and the material for crushing. At the same time, as the pressure plate 6 moves downward, the top of the traction cable 75 no longer pulls the feed hopper 3. At this time, under the action of gravity, the feed hopper 3 slides downward, and the flip baffle 91 flips back and resets, and then prepares for the second material loading.

[0041] After the initial crushing of the raw materials, the materials fall downward into the conical crushing bin 51. At this time, the first drive motor 53 is started, so that the first drive motor 53 drives a group of crushing rollers 55 to rotate through a transmission belt 54. The crushing rollers 55 are connected to each other through a second transmission gear 56 that meshes in sequence. The multiple groups of crushing rollers 55 arranged in an annular shape in the conical crushing bin 51 rotate synchronously, thereby achieving further rapid crushing of the falling materials and achieving smaller particle size of the crushed materials.

[0042] The crushed material falls downward into the inside of the discharge pipe 41. At this time, by starting the pneumatic conveying fan 44, a directional airflow is formed inside the discharge pipe 41, thereby driving the falling crushed material to move forward into the inside of the N-shaped connecting pipe 43. At this time, the sliding sealing plate 45 is on one side of the discharge pipe 41. At this time, the material will be discharged through the other end of the N-shaped connecting pipe 43 and stored in a set of storage bags 42;

[0043] At the same time, when the storage bag 42 is about to be full, the adjusting screw 46 is rotated so that the adjusting screw 46 rotates on the outer surface of the sliding sealing plate 45, thereby driving the sliding sealing plate 45 to slide to the other end inside the N-shaped connecting tube 43. At this time, the discharge pipe 41 is connected to the storage bag 42 on the other side, thereby realizing continuous operation without stopping the machine and facilitating the replacement of the storage bag 42.

[0044] The basic principles, main features, and advantages of the present invention are shown and described above. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
