Description

Technical Field

[0001] The utility model relates to the technical field of raw material crushing devices for paper production, in particular to a raw material crushing device for paper production. Background Art

[0002] The main raw materials for papermaking include wood, herbaceous plants, recycled fibers, etc. Wood is divided into coniferous wood and hardwood wood, and their fiber structures and strength characteristics are different. The fibers of herbaceous raw materials are shorter and the cell walls are thinner. Recycled fibers may contain different types of paper fibers and may also be mixed with impurities such as ink and adhesives. These different raw materials need to be broken into suitable fiber states before papermaking. For example, wood logs or wood chips need to be further refined to release fibers for the subsequent pulping process.

[0003] During the production of paper, a crushing device is required to crush the raw materials. However, the existing crushing devices do not have the grinding function and cannot guarantee the crushing efficiency, which brings great inconvenience to the preparation of paper.

[0004] The existing patent (Announcement No.: CN212493167U) is a raw material crushing device for paper production. Through the coordinated use of a crushing box, a first support plate, a first motor, a second motor, a first crushing roller, a second crushing roller, a blade, a guide plate, a grinding roller, a connecting frame, a crank rocker, a turntable, a third motor, a second support plate, a grinding plate and an electromagnetic valve, the raw material can be crushed and then ground, greatly ensuring the crushing effect of the raw material. The discharged raw material can be used directly without the need for multiple grinding, which greatly facilitates the paper preparation work. The feed hopper can better feed the raw material, which brings convenience to the crushing work. The support legs can better ensure the stability of the equipment and better ensure the progress of the crushing work. The discharge pipe can discharge the ground raw material, which better ensures the progress of the discharge work. The slider and the chute can limit the connecting frame, thereby driving the grinding roller to move left and right, which better ensures the progress of the grinding work. The push plate and the electric telescopic rod can push the material on the surface of the grinding plate together, which better ensures the grinding efficiency.

[0005] In response to the above problems, the existing patent provides a solution. When the existing raw material crushing device for paper production crushes wet paper, the presence of moisture between the fibers of the wet paper has a certain cohesive force, which hinders the effective contact between the crushing medium and the paper, thereby reducing the crushing efficiency. Moreover, when collecting the crushed paper later, it is inconvenient to manually collect a large amount of crushed raw materials in a short time, which will cause the raw materials to accumulate around the crushing device, affecting the normal operation of the crushing device.

[0006] Therefore, a raw material crushing device for paper production is proposed. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figure 1-5 , this utility model provides a technical solution:

[0028] A paper production raw material crushing device includes a processing box 1, the top of the processing box 1 is connected to a feed hopper 20, the front side of the processing box 1 is bolted to a motor box 2, the output end of the motor box 2 passes through the front side of the processing box 1, and the output end of the motor box 2 is fixedly connected to a crushing roller 3, the rear side of the processing box 1 is provided with a heating component 5, the bottom side of the processing box 1 is provided with a placement groove 4, and the bottom of the processing box 1 is provided with a collection component 6, which includes a drive motor 601 bolted to the inside of the placement groove 4;

[0029] The heating assembly 5 includes a support platform 501 bolted to the rear side of the processing box 1, the top of the support platform 501 is bolted to the box body 502, the rear side of the inside of the box body 502 is bolted to a support rod 503, the front side of the support rod 503 is fixedly connected to the fan body 504, the front side of the inside of the box body 502 is bolted to a heating rod 505, the heating rod 505 is located on the front side of the fan body 504, the front side of the box body 502 is connected to a delivery pipe 506, the front side of the delivery pipe 506 is connected to the rear side of the processing box 1, and the rear side of the box body 502 is bolted to a filter plate 507.

[0030] In this embodiment: by starting the heating rod 505, the heating rod 505 begins to heat up, and at the same time the fan body 504 is started, and then the fan body 504 begins to rotate under the support of the support rod 503, and then the fan rotates to generate airflow to blow the heat generated by the heating rod 505 to the inside of the processing box 1 through the conveying pipe 506, and then the filter plate 507 on the rear side of the box body 502 can prevent impurities from entering the interior of the heating component 5 and affecting its normal operation. Compared with the existing raw material crushing device for paper production, it can heat the wet paper, evaporate the moisture in the paper, reduce the humidity of the paper, thereby reducing the cohesion between the fibers, and thus improving the crushing efficiency.

[0031] Specifically, such as Figure 3 、 Figure 4 As shown, the output end of the driving motor 601 is fixedly connected to a threaded rod 602 , the left side of the threaded rod 602 is rotatably connected to the inner side of the placement slot 4 , and the outer side of the threaded rod 602 is threadedly connected to a connecting block 603 .

[0032] Specifically, such as Figure 3 、 Figure 4 As shown, a collecting box 604 is fixedly connected to the inner side of the connecting block 603 , and a groove 605 is provided on the left side of the processing box 1 .

[0033] Specifically, such as Figure 3 、 Figure 4 As shown, a rotating block 606 is fixedly connected to the inside of the groove 605 , a rotating rod 607 is rotatably connected to the inside of the rotating block 606 , and a baffle 608 is fixedly connected to the bottom of the rotating rod 607 . The baffle 608 is located on the left side of the collection box 604 .

[0034] In this embodiment: by starting the driving motor 601, the output end of the driving motor 601 drives the threaded rod 602 to rotate. Since the outer side of the threaded rod 602 is threadedly connected to the connecting block 603, and the left side of the threaded rod 602 is rotatably connected to the inner side of the placement groove 4, the connecting block 603 will move along the threaded rod 602 under the rotation of the threaded rod 602, and then the collection box 604 will move with the movement of the connecting block 603. When the collection box 604 moves to the left, the baffle 608 will rotate upward under the action of the rotating rod 607 and will not hinder the movement of the collection box 604. When the collection box 604 moves to the right, the baffle 608 will rotate downward under the action of gravity, blocking the left opening of the collection box 604, preventing the raw materials in the collection box 604 from falling. Compared with the existing raw material crushing device for paper production, the collection speed is greatly improved, the accumulation of raw materials around the crushing device is avoided, and the normal operation of the crushing device is ensured.

[0035] Specifically, such as Figure 5As shown, a placement plate 7 is fixedly connected to the bottom of the processing box 1, and limiting grooves 8 are provided on both sides of the placement plate 7. A stopper 9 is fixedly connected inside the limiting groove 8, and a guide plate 10 is fixedly connected inside the placement plate 7. The bottom of the placement plate 7 is connected to a drain pipe 11, and an electromagnetic valve 12 is provided on the outside of the drain pipe 11.

[0036] Specifically, such as Figure 4 As shown, a slot 13 is provided inside the processing box 1 , a motor body 14 is bolted inside the slot 13 , a screw rod 15 is fixedly connected to the output end of the motor body 14 , and a push plate 16 is threadedly connected to the outer side of the screw rod 15 .

[0037] In this embodiment: by providing a placement plate 7, a limiting groove 8, a block 9, a guide plate 10, a conveying pipe 506 and an electromagnetic valve 12, when the wet paper is heated, the moisture generated by the heating flows into the interior of the placement plate 7 through the limiting groove 8, and at the same time the block 9 effectively prevents the paper from entering the interior of the placement plate 7, and then the guide plate 10 guides the residual moisture, and then by starting the electromagnetic valve 12, it is discharged through the conveying pipe 506, and by providing a card slot 13, a motor body 14, a screw rod 15 and a push plate 16, when the wet paper is dried, the motor body 14 is started, and then the output end of the motor body 14 drives the screw rod 15 to rotate. Since the outer side of the screw rod 15 is threadedly connected to the push plate 16, as the screw rod 15 rotates, the push plate 16 will move along the screw rod 15, and then the push plate 16 pushes the dried paper to move to the crushing roller 3 for crushing.

[0038] Specifically, such as Figure 1 As shown, a top cover 17 is clamped on the top of the feed hopper 20 , and a pull rod 18 is bolted to the top of the top cover 17 .

[0039] Specifically, such as Figure 1 As shown, a non-slip pad 19 is bonded to the bottom side of the processing box 1, and the non-slip pad 19 is made of rubber.

[0040] In this embodiment: by setting the top cover 17 and the pull rod 18, when the raw materials are put in, the top cover 17 is snapped back to the top of the feed hopper 20 to prevent the raw materials from splashing out of the feed hopper 20, and at the same time, it can also prevent external dust and other impurities from entering the feed hopper 20 and contaminating the raw materials. By setting the anti-slip pad 19, the anti-slip pad 19 can increase the friction between the device and the ground, preventing the device from sliding due to vibration and other reasons during operation, thereby improving the stability of the device.

[0041] Working principle: When using the paper production raw material shredding device, first, the paper to be shredded is added through the feed hopper 20. When the wet paper is added, the heating rod 505 is started, and then the heating rod 505 starts to heat up, and the fan body 504 is started at the same time. Then the fan body 504 starts to rotate under the support of the support rod 503. Then the fan rotates to generate airflow to blow the heat generated by the heating rod 505 to the inside of the processing box 1 through the conveying pipe 506. Then the filter plate 507 on the back side of the box body 502 can prevent impurities from entering the interior of the heating component 5 and affecting it. Normal operation, when the wet paper is dried, the motor body 14 is started, and then the output end of the motor body 14 drives the screw rod 15 to rotate. Since the outer side of the screw rod 15 is connected with a push plate 16 through a thread, as the screw rod 15 rotates, the push plate 16 moves along the screw rod 15, and then the push plate 16 pushes the dried paper to move to the crushing roller 3 for crushing, and then the motor box 2 is started, and then the motor box 2 causes the crushing roller 3 to crush its paper. When the crushing is completed, the crushed paper falls into the inside of the collection box 604, and then the drive motor 60 is started. 1, then the output end of the driving motor 601 drives the threaded rod 602 to rotate. Since the outer side of the threaded rod 602 is connected to the connecting block 603 by a thread, and the left side of the threaded rod 602 is rotatably connected to the inner side of the placement groove 4, the connecting block 603 will move along the threaded rod 602 under the rotation of the threaded rod 602, and then the collection box 604 will move with the movement of the connecting block 603. When the collection box 604 moves to the left, the baffle 608 will rotate upward under the action of the rotating rod 607, and will not hinder the movement of the collection box 604. When the collection box 604 moves to the right, the baffle 608 will rotate downward under the action of gravity, blocking the left opening of the collection box 604 to prevent the raw materials in the collection box 604 from falling. This solves the problem that when the existing raw material crushing device for paper production crushes wet paper, the presence of moisture between the fibers of the wet paper has a certain cohesive force, thereby hindering the effective contact between the crushing medium and the paper, thereby reducing the crushing efficiency. In addition, when collecting the crushed paper subsequently, it is inconvenient to manually collect a large amount of crushed raw materials in a short time, which will cause the raw materials to accumulate around the crushing device, affecting the normal operation of the crushing device.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
