Specific implementation manner

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0023] The present utility model provides a technical solution: As Figures 1 to 6 shown, in this embodiment, a paper recycling and crushing device includes a base 1. Two vertical plates 2 are symmetrically installed on the upper surface of the base 1. An annular frame 3 is fixedly installed between the two vertical plates 2. A circulating extrusion mechanism is rotatably installed in the annular frame 3. The circulating extrusion mechanism is used to perform a circulating extrusion action on the crushed paper. A crushing mechanism cooperating with the circulating extrusion mechanism is installed on the top of the annular frame 3. The crushing mechanism is used to crush the paper. At the same time, a feeding mechanism cooperating with the circulating extrusion mechanism is installed at the bottom of the annular frame 3. The feeding mechanism is used to perform an active feeding operation on the paper after extrusion is completed.

[0024] As Figure 5As shown, the pulverizing mechanism includes a pulverizing box 4 connected and installed on the top of the annular frame 3. The pulverizing box 4 is of a through-type design, and a feed hopper is installed on the top of the pulverizing box 4. At the same time, two guide plates are symmetrically installed on the top of the feed hopper to guide the position of the paper. Two pulverizing knife rollers 5 are symmetrically installed at the bottom of the pulverizing box 4 for rotation, and two reduction motors 6 are symmetrically installed on one side of the pulverizing box 4. The output ends of the two reduction motors 6 are respectively connected to the two pulverizing knife rollers 5 for transmission. The two pulverizing knife rollers 5 rotate away from the reduction motor 6 and pass through the side wall of the pulverizing box 4. Two conveying rollers 7 are symmetrically installed at the top of the pulverizing box 4 for rotation. The two conveying rollers 7 are distributed at intervals, and one end of the two conveying rollers 7 rotates and extends out of the pulverizing box 4. A first pulley 8 is fixedly sleeved on one end of the two pulverizing knife rollers 5, and a second pulley 9 is fixedly sleeved on one end of the two conveying rollers 7. A power belt 10 is provided between the first pulley 8 and the second pulley 9. The sizes of the first pulley 8 and the second pulley 9 are adjusted according to work requirements.

[0025] It is worth mentioning that: when shredding is performed: a shredding mechanism is provided, and the paper is introduced into the shredding box 4 through the feed hopper and contacts with the two conveying rollers 7. At the same time, the two reduction motors 6 are started to drive the two shredding knife rollers 5 to rotate. At the same time, under the transmission of the power belt 10, the first pulley 8 and the second pulley 9, the power of the two shredding knife rollers 5 can be transmitted to the conveying rollers 7, so that the two conveying rollers 7 follow the rotation and guide the paper to the two shredding knife rollers 5. Subsequently, the paper is shredded by the two shredding knife rollers 5. Through the design of the two conveying rollers 7, the paper can be stably introduced into the shredding knife rollers 5 to avoid the paper from retreating. Then the shredded paper enters the extrusion chamber 13.

[0026] like Figures 2 to 4 and Figure 6 As shown, the circulating extrusion mechanism includes a turntable 11 rotatably mounted in the annular frame 3, and the two sides of the turntable 11 rotate with the inner walls of the two vertical plates 2 respectively, and a flip motor 12 is installed on the side wall of one of the vertical plates 2, and the output end of the flip motor 12 is transmission-connected with the turntable 11, and four extrusion chambers 13 are arranged in a circular array around the turntable 11, and the extrusion chambers 13 are open on the turntable 11 and communicate with the crushing box 4, and the size of the extrusion chambers 13 is larger than the size of the crushing box 4, so that the crushed paper can smoothly enter the extrusion chamber 13, and the four extrusion chambers 13 are all installed with gravity members 14, and the gravity members 14 can slide in the extrusion chambers 13 to complete the extrusion action, and the gravity members 14 include a counterweight plate 141 slidably mounted in the extrusion chamber 13, and a pull rope 142 is installed at the bottom of the extrusion chamber 13, and the top of the pull rope 142 is detachably fixedly connected to the bottom of the counterweight plate 141, and a storage area for storing the pull rope 142 is opened at the bottom of the extrusion chamber 13;

[0027] It is worth noting that: when performing cyclic extrusion: a cyclic extrusion mechanism is provided, and the extrusion chamber 13 completes receiving the paper. When the extrusion chamber 13 is fully loaded, the flip motor 12 is started, and then the unloaded extrusion chamber 13 is transferred to the bottom of the crushing box 4. The fully loaded extrusion chamber 13 rotates accordingly, thereby completing the cyclic material receiving action. At the same time, when the extrusion chamber 13 opens toward the base 1, the counterweight plate 141 moves downward under the action of gravity, thereby completing the extrusion molding of the paper in the extrusion chamber 13. The extrusion work can be completed without external power, which saves time and effort and reduces the operating cost of the equipment. Finally, the material is unloaded through the unloading mechanism. After the subsequent unloading, the extrusion chamber 13 circulates to the bottom of the crushing box 4 again. At this time, the counterweight plate 141 slides to the bottom of the extrusion chamber 13 again under the guidance of gravity to wait for material receiving. At the same time, a pull rope 142 is added, so that the counterweight plate 141 can be restricted during sliding, which is more stable.

[0028] The feeding mechanism includes a feeding channel 15 connected and installed at the bottom of the annular frame 3. The feeding channel 15 is connected to the extrusion chamber 13, and the size of the feeding channel 15 is larger than the size of the extrusion chamber 13, so that the extruded paper can be fed smoothly. A blocking plate 16 is slidably installed at the bottom of the feeding channel 15. The blocking plate 16 is used to block the feeding channel 15, and an electric push rod 17 is installed on one side of the upper surface of the base 1. The output end of the electric push rod 17 is transmission-connected to one side of the blocking plate 16.

[0029] It is worth noting that when unloading: a unloading mechanism is provided, the electric push rod 17 is started, and the blocking plate 16 is pulled to move the unloading channel 15 to open the unloading channel 15, so that the squeezed paper falls onto the base 1 to complete the unloading. After a single unloading is completed, the electric push rod 17 is reset, and the unloading channel 15 is blocked again by the blocking plate 16 to prevent the paper from accidentally falling.

[0030] The utility model provides a paper recycling and crushing device, and the specific working principle is as follows: First, the paper is put into the crushing box 4, and then the crushing mechanism completes the crushing action on the paper in the crushing box 4. At the same time, during the crushing process, the crushing mechanism synchronously drives the conveying roller 7 to work, so as to complete the rotational guidance of the paper, enabling the paper to smoothly contact the crushing cutter roller 5 to complete crushing, improving the crushing efficiency. Subsequently, the crushed paper enters the extrusion chamber 13. When a single extrusion chamber 13 is full, the flipping motor 12 is started to drive the turntable 11 to flip to complete the switching of each extrusion chamber 13. At the same time, the position of the full extrusion chamber 13 is converted. After the conversion is completed, the gravity member 14 in the extrusion chamber 13 moves downward under the action of gravity to complete the extrusion molding of the paper in the extrusion chamber 13, which is beneficial for subsequent packaging. At the same time, the extruded paper is discharged through the blanking mechanism. Subsequently, the turntable 11 continues to rotate. In this action, the gravity member 14 will be reset to the bottom of the extrusion chamber 13 again under the action of gravity. The overall operation of the device is stable, and it does not require external power to complete the extrusion molding of the paper. At the same time, it can be freely reset, improving the crushing efficiency and reducing the workload of manual labor.
