Description

Technical Field

[0001] The utility model relates to the technical field of corrugated core paper preparation, in particular to a pulping production line for corrugated core paper. Background Art

[0002] In the corrugated paper pulping process, recycling waste paper is an important means of reducing costs and improving resource efficiency. However, waste paper inevitably contains various impurities, with metallic impurities being particularly problematic. These impurities not only affect pulp quality but can also severely damage pulping equipment, particularly during the pulping stage.

[0003] Regarding the existing related technologies, the inventors believe that the following defects often exist: magnetic metal impurities in waste paper raw materials, such as nails, screws, metal sheets, etc., will frequently collide with the stirring blades after entering the pulping drum as the stirring blades rotate. This collision not only accelerates the wear of the stirring blades, but may also cause the stirring blades to deform or even break, seriously affecting the normal operation and service life of the equipment. In addition, metal impurities may also damage other components inside the pulping drum, such as screens, bearings, etc., further increasing maintenance costs and downtime.

[0004] Therefore, we propose a pulping production line for corrugated core paper. Utility Model Content

[0005] In view of the problem that magnetic metal impurities in the above-mentioned existing waste paper raw materials, such as iron nails, screws, metal sheets, etc., will frequently collide with the stirring blades as they rotate after entering the pulping drum, and such collisions not only accelerate the wear of the stirring blades, but may also cause the stirring blades to deform or even break, seriously affecting the normal operation and service life of the equipment, the present utility model is proposed.

[0008] A rotating shaft is rotatably installed on both sides of the feed bin, and a limiting plate is sleeved on the outer wall of the rotating shaft, and the limiting plates on both sides form a discharge channel;

[0009] A magnet plate 1 and a magnet plate 2 are installed inside the U-shaped bin and in the inner cavity of the conveyor belt, and the metal magnetic surfaces of the magnet plate 1 and the magnet plate 2 are located near one end of the conveyor belt.

[0010] As an optimal solution of the pulping production line for corrugated core paper described in the utility model, drive rollers are rotatably installed on both sides of the inside of the U-shaped bin, and the conveyor belt drive is installed between the two drive rollers, and a servo motor for driving the drive rollers to rotate is installed on the back of the U-shaped bin and on the side close to the feed bin.

[0011] As a preferred solution of the corrugated core paper pulping production line described in the utility model, a ring magnet is installed in the inner cavity of the driving roller close to the second side of the magnet plate, and the magnetic surface of the ring magnet is located on the side close to the driving roller.

[0012] As a preferred solution of the pulping production line for corrugated core paper of the utility model, a discharge port is provided at the bottom of the U-shaped bin and on one side close to the second magnet plate.

[0017] Beneficial effects of the utility model:

When the raw materials are conveyed on the conveyor belt, the annular magnet, the first magnet plate and the second magnet plate adsorb the magnetic metal impurities and fix them on the outer wall surface of the conveyor belt, thereby preventing the magnetic metal impurities from falling into the interior of the pulper with the raw materials, thereby avoiding damage to the pulper by the magnetic metal impurities.

[0019] 2. In the present invention, the extension of the electric telescopic rod drives the two rotating shafts to rotate, so that the two limiting plates rotate toward the middle at the same time, so as to reduce the distance between the limiting plates on both sides and narrow the discharge channel. Conversely, the shortening of the electric telescopic rod can expand the distance between the limiting plates on both sides and expand the discharge channel. The size of the discharge channel can be adaptively adjusted according to actual conditions. At the same time, when the material is stuck in the discharge channel, the jammed material can be discharged outward by expanding the discharge channel, which is convenient for handling the jammed material.

[0020] 3. In the utility model, the driving motor drives the rotating roller to rotate through the belt transmission part. When the rotating roller rotates, it drives the convex strips to rotate. When the convex strips rotate, they come into contact with the materials on the conveyor belt. The convex strips push the materials stacked too high on the conveyor belt, thereby reducing the height of the raw material stacking. It is also more conducive to exposing the magnetic metal impurities in the raw materials, which is more conducive to their being magnetically attracted to the conveyor belt.

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0030] Example 1

[0031] Reference Figure 1-5 , which is the first embodiment of the present utility model, provides a pulping production line for corrugated core paper, which includes a U-shaped bin 1 with legs welded to the bottom, and a feed bin 3 welded to one side of the U-shaped bin 1 through a bracket, a conveyor belt 11 is installed in the inner cavity of the U-shaped bin 1, and shielding belts 12 are installed on the front and rear sides of the outer wall of the conveyor belt 11. The setting of the shielding belt 12 plays a limiting role on the raw materials on the conveyor belt 11, preventing the raw materials on the conveyor belt 11 from separating from the surface of the conveyor belt 11. A pulper 4 is provided below the end of the conveyor belt 11 away from the feed bin 3, and a material distribution component 2 is installed in the middle position of the U-shaped bin 1;

[0032] A rotating shaft 33 is rotatably mounted on both sides of the feed bin 3. A limiting plate 32 is sleeved on the outer wall of the rotating shaft 33. The limiting plates 32 on both sides form a discharge channel. The setting of the limiting plates 32 on both sides controls the amount of raw materials falling, avoids excessive materials from falling uniformly, and ensures the uniformity of the materials falling onto the conveyor belt 11, which is more conducive to exposing the magnetic metal impurities mixed in the raw materials.

[0033] A magnet plate 15 and a magnet plate 2 16 are installed inside the U-shaped bin 1 and in the inner cavity of the conveyor belt 11, and the metal magnetic surfaces of the magnet plate 15 and the magnet plate 2 16 are located at one end close to the conveyor belt 11. When the raw materials are conveyed on the conveyor belt 11, the annular magnet 14, the magnet plate 15 and the magnet plate 2 16 adsorb the magnetic metal impurities and fix them on the outer wall surface of the conveyor belt 11 to prevent the magnetic metal impurities from falling into the interior of the pulper 4 with the raw materials, thereby avoiding damage to the pulper 4 by the magnetic metal impurities.

[0034] Drive rollers 13 are rotatably installed on both sides of the U-shaped warehouse 1, and the conveyor belt 11 is installed between the two drive rollers 13. A servo motor for driving the drive roller 13 to rotate is installed on the back of the U-shaped warehouse 1 and close to the side of the feed warehouse 3, and the drive end of the servo motor is connected to the shaft end of the drive roller 13.

[0035] An annular magnet 14 is installed in the inner cavity of the driving roller 13 near the side of the magnet plate 2 16, and the magnetic surface of the annular magnet 14 is located on the side close to the driving roller 13. The setting of the annular magnet 14 can also adsorb magnetic metal impurities on the outer wall surface of the conveyor belt 11 when the conveyor belt 11 turns, thereby preventing the magnetic metal impurities from accidentally falling off.

[0036] A discharge port 17 is provided at the bottom of the U-shaped bin 1 and on one side close to the second magnet plate 16 .

[0037] The material distribution component 2 includes two vertical frames 21 welded on the U-shaped bin 1, and a rotating roller 22 is rotatably installed between the two vertical frames 21. The outer wall of the rotating roller 22 is welded with multiple ridges 23. A driving motor 25 is installed inside the U-shaped bin 1, and a belt transmission member 24 is installed between the driving end of the driving motor 25 and the shaft end of the rotating roller 22. The belt transmission member 24 consists of two pulleys and a belt. The belt transmission is installed between the two pulleys. The driving motor 25 drives the rotating roller 22 to rotate through the belt transmission member 24. When the rotating roller 22 rotates, it drives the ridges 23 to rotate. When the ridges 23 rotate, they will contact the material on the conveyor belt 11. The ridges 23 will push the materials stacked too high on the conveyor belt 11, reduce the height of the raw material stacking, and make it easier for the magnetic metal impurities in the raw materials to be exposed, making it easier for them to be magnetically attracted to the conveyor belt 11.

[0038] During use, the raw materials are placed in the feed bin 3. The raw materials in the feed bin 3 are guided by the limiting plates 32 on both sides and fall onto the conveyor belt 11. The servo motor drives the driving roller 13 to rotate, so that the conveyor belt 11 is in a rotating state, and the raw materials are transported toward the pulper 4.

[0039] The setting of the material limiting plates 32 on both sides controls the amount of raw materials falling, avoiding excessive materials from falling uniformly;

[0040] When the raw materials fall onto the conveyor belt 11, the magnetic impurities are magnetically attracted to the outer wall of the conveyor belt 11 by the magnetic attraction of the first magnet plate 15 and the second magnet plate 16. When the raw materials are conveyed to the discharge end of the conveyor belt 11, the magnetic impurities are attracted to the outer wall of the conveyor belt 11, and the raw materials fall into the pulper 4 for pulping.

[0041] When the magnetic impurities are separated from the position of the second magnet plate 16 , there is no magnetic attraction, and the magnetic impurities fall under the action of gravity and are discharged outward through the discharge port 17 .

[0042] Example 2

[0043] Reference Figure 1-5 , which is the second embodiment of the present utility model, is different from the first embodiment in that:

[0044] An electric telescopic rod 34 is installed on the back of the feed bin 3 through a rod frame. The movable end of the electric telescopic rod 34 is fixedly connected to a lifting plate 35. Racks 36 are installed at both ends of the top of the lifting plate 35. The end of the rotating shaft 33 close to the electric telescopic rod 34 protrudes from the outside of the feed bin 3, and the end of the rotating shaft 33 close to the electric telescopic rod 34 is covered with a gear 37 that meshes with the rack 36.

[0045] The extension of the electric telescopic rod 34 drives the two rotating shafts 33 to rotate, causing the two limiting plates 32 to rotate toward the middle at the same time, so as to reduce the distance between the limiting plates 32 on both sides and narrow the discharge channel. Conversely, the electric telescopic rod 34 is shortened to expand the distance between the limiting plates 32 on both sides and expand the discharge channel. The size of the discharge channel can be adaptively adjusted according to actual conditions. At the same time, when material is stuck in the discharge channel, the discharge channel can be expanded to discharge the stuck material outward, making it convenient to deal with the stuck material situation.

[0046] On both sides of the inner wall of the feed bin 3 and above the rotating shaft 33, there are welded blocking inclined plates 31 for blocking the rotating shaft 33. The setting of the blocking inclined plates 31 on both sides has the effect of blocking the rotating shaft 33, preventing the material from getting stuck between the rotating shaft 33 and the inner wall of the feed bin 3 and affecting the normal rotation of the limiting plate 32.

[0047] Tripods are fixed to opposite surfaces of the two racks 36 , and the bottoms of the tripods are fixed to the top of the lifting plate 35 .

[0048] During use, the extension of the electric telescopic rod 34 drives the lifting plate 35 to move upward, and under the meshing transmission action of the rack 36 and the gear 37, the two rotating shafts 33 are driven to rotate at the same time, so that the two limiting plates 32 rotate toward the middle at the same time to reduce the distance between the limiting plates 32 on both sides and narrow the discharge channel. Conversely, the electric telescopic rod 34 is shortened to expand the distance between the limiting plates 32 on both sides and expand the discharge channel.

[0049] The remaining structures are the same as those of Example 1.

[0050] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
