[0002] Boxboard, also known as hemp cardboard, is a relatively sturdy cardboard used specifically for outer packaging. Available in both standard and premium grades, it has a smooth surface and a light yellowish-brown hue. It possesses high mechanical strength, folding resistance, and tear resistance. In boxboard production, recycled waste cardboard is typically used. After soaking and pulping, it undergoes papermaking and other processes to produce new paper. This processed boxboard is suitable for office and school use and is beneficial for protecting eyesight. With the growing global awareness of environmental protection, the use of recycled paper is a highly popular initiative.

The paper cutter cuts the waste cardboard into pieces and puts the shredded paper into the kneading basin. A water pipe is installed on the other side of the top of the soaking box to supply water to the kneading basin. The kneading head will rotate as the lifting seat descends, kneading the shredded paper soaked in the kneading basin to form a thicker pulp, which then flows to the beating cylinder for beating through the beating assembly to form the pulp required for the final production. After the pulp is processed, it can be discharged uniformly through the discharge valve.

The top of the pressing paper board is fixedly connected to a guide slide bar, and the guide slide bar slides with the convex plate, and an elastic part is connected between the convex plate and the pressing paper board. The elastic part is a pressure spring. When the rack rod moves downward, the pressing paper board can be used to buffer and press the top of the stacked waste paper boards, thereby preventing the stacked waste paper boards from being misaligned and affecting paper cutting.

[0014] The present invention provides a kneading head that can be raised and lowered above the kneading basin, and uses an inclined guide rod to guide the rack rod at an angle, so that the rack rod moves laterally while following the rise and fall of the lifting seat, and then uses the engagement of the gear sleeve and the rack rod to drive the kneading head to rise and fall and rotate at the same time, kneading the shredded paper soaked in water in the kneading basin to form a thicker pulp, and with the repeated rise and fall of the kneading head, the pulp overflows from the kneading basin into the soaking box, and flows to the beating drum for beating by the beating assembly, thereby forming the pulp required for the final production, thereby greatly improving the processing efficiency of the pulp, enhancing the processing quality of the pulp, and improving the quality of the boxboard finally produced.

[0015] The present invention provides a waste paper trough on the soaking box, stores the stacked waste paper boards into the waste paper trough, and utilizes the lifting and lowering of the lifting seat and the guidance of the inclined guide rod to make the cutter slide back and forth at the end of the waste paper trough.

[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings. Example

[0025] The present invention provides Figure 1 and Figure 2The pulp processing equipment for producing boxboard shown in the figure comprises a soaking box 1, one side of the soaking box 1 is concave to form a beating cylinder 12, the outer side of the beating cylinder 12 is provided with a discharge valve 13, and the beating cylinder 12 is provided with a beating assembly, the interior of the soaking box 1 is fixedly installed with a kneading basin 11, and a lifting seat 2 is provided above the kneading basin 11. The lifting seat 2 is installed to slide up and down relative to the soaking box 1, and the lifting seat 2 is driven by a lifting drive 3. The lifting drive 3 can be a hydraulic cylinder, a cylinder or the like. The lifting seat 2 is rotatably installed with a pressure rod 21, and a kneading head 22 is installed at the bottom end of the pressure rod 21. The bottom surface of the kneading head 22 is adapted to the inner wall of the kneading basin 11, and both surfaces are provided with grinding protrusions. An inclined guide rod 8 is fixedly installed on one side of the top of the soaking box 1, and a rack rod 5 is slidably installed inside the lifting seat 2. A gear sleeve 23 engaged with the rack rod 5 is fixedly connected to the pressure rod 21, and one end of the rack rod 5 is slidably matched with the inclined guide rod 8. A paper cutter 4 is provided on the side of the top of the soaking box 1 near the inclined guide rod 8. The paper cutter 4 cuts the waste cardboard into pieces and puts the shredded paper into the kneading basin 11. A water diversion pipe 7 is installed on the other side of the top of the soaking box 1. The water diversion pipe 7 supplies water to the kneading basin 11. The lifting driver 3 controls the lifting and lowering of the lifting seat 2, and then uses the inclined guide rod 8 to guide the tilt of the rack rod 5, synchronously driving the rack rod 5 and the pressure rod 21 to move relative to each other, thereby driving the pressure rod 21 to rotate, that is, the kneading head 22 will also rotate while following the lowering of the lifting seat 2, thereby kneading the shredded paper soaked in the kneading basin 11. The pulp is pressed to form a thicker pulp, and as the kneading and rolling head 22 repeatedly rises and falls and kneads, the pulp becomes finer, until the pulp in the kneading and rolling basin 11 gradually increases, overflows from the kneading and rolling basin 11 into the soaking box 1, and flows to the beating cylinder 12 for beating by the beating assembly, thereby forming the pulp required for the final production, and after the pulp is processed, it can be uniformly discharged through the discharge valve 13, thereby greatly improving the processing efficiency of the pulp, enhancing the processing quality of the pulp, and improving the quality of the final produced boxboard;

[0026] Furthermore, in the above technical solution, if Figure 4 As shown, the top of the immersion box 1 is fixedly connected to a support frame 14, the inner side of the support frame 14 is provided with a guide rail, the lifting seat 2 is slidably installed on the guide rail, and the lifting drive 3 is fixedly installed on the support frame 14, thereby supporting the stable lifting of the lifting seat 2;

[0027] Furthermore, in the above technical solution, the top of the kneading and rolling head 22 is fixedly connected to a spline shaft 24, and the spline shaft 24 is slidably inserted into the interior of the pressure rod 21, that is, the kneading and rolling head 22 and the pressure rod 21 cannot rotate relative to each other, and an elastic member is connected between the pressure rod 21 and the kneading and rolling head 22, and the elastic member is a pressure spring, which pushes the kneading and rolling head 22 to move downward. After the kneading and rolling head 22 contacts the kneading basin 11, the kneading and rolling head 22 only rotates with the pressure rod 21 and no longer moves downward, while the sliding support between the spline shaft 24 and the pressure rod 21 continues to move downward, thereby providing more time for the kneading and rolling head 22 to rotate and press in the kneading basin 11, so as to further improve the effect of kneading and rolling the shredded paper and increase the processing speed;

[0028] Furthermore, in the above technical solution, the water diversion pipe 7 is fixedly installed on the top of the soaking box 1, and one end of the water diversion pipe 7 extends to the top of the kneading basin 11. A pressing valve 71 corresponding to the rack rod 5 is installed inside the water diversion pipe 7. When the rack rod 5 moves down with the lifting seat 2 to press the pressing valve 71, the pressing valve 71 is started to supply water to the kneading basin 11, and the water supply is stopped after the rack rod 5 leaves the pressing valve 71. Thus, water can be supplied to the kneading basin 11 at intervals, thereby avoiding excessive continuous water supply that affects the kneading of shredded paper.

[0029] Working principle: A kneading basin 11 is installed in the soaking box 1, and a kneading head 22 that can be raised and lowered is set above the kneading basin 11. The rack rod 5 is tilted and guided by the inclined guide rod 8, so that the rack rod 5 moves horizontally while following the lifting and lowering of the lifting seat 2, and then the engagement between the gear sleeve 23 and the rack rod 5 drives the kneading head 22 to rise and fall and rotate at the same time. The waste cardboard is shredded by the paper cutter 4, and the shredded paper is put into the kneading basin 11 and soaked in a small amount of water first. When the lifting seat 2 is controlled to descend, the kneading head 22 rotates and presses down, thereby The shredded paper soaked in water in the basin 11 is kneaded to form a thicker pulp, and as the kneading head 22 is repeatedly raised and lowered, the pulp becomes finer, until the pulp in the kneading basin 11 gradually increases, and then overflows from the kneading basin 11 into the soaking box 1, and flows to the beating drum 12 for beating by the beating assembly, thereby forming the pulp required for the final production, and after the pulp is processed, it can be uniformly discharged through the beating drum 12, thereby greatly improving the processing efficiency of the pulp, enhancing the processing quality of the pulp, and improving the quality of the final produced boxboard. Example

[0030] Based on Example 1, Figures 1 to 3The paper pulp processing equipment for boxboard production shown in the figure includes a paper cutter 4 including a waste paper chute 41, the waste paper chute 41 is fixedly mounted on the top of the soaking box 1, and the end of the waste paper chute 41 extends to the top of the kneading basin 11, and the inclined guide rod 8 is fixedly mounted on the top of the waste paper chute 41. The waste paper chute 41 slides to store the compressed and stacked waste paper boards, and a pushing plate 42 is slidably mounted in the waste paper chute 41 to push the waste paper boards outward. A cutter 51 is fixedly connected to the end of the rack rod 5 close to the waste paper chute 41, and the cutter 51 is slidably matched with the end of the waste paper chute 41. Then, by lifting and lowering the lifting seat 2 and guiding the inclined guide rod 8, the cutter 51 is tilted and slid back and forth at the end of the waste paper chute 41, and then cooperates with the pushing plate 42 to push out a small amount of waste paper boards when the cutter 51 is raised. Then, during the subsequent downward movement of the rack rod 5, the cutter 51 cuts the protruding waste paper boards, and the shredded paper falls into the kneading basin 11 to wait for subsequent kneading processing.

[0031] Furthermore, in the above technical solution, a threaded sleeve 44 is rotatably mounted on the inner side of the waste paper chute 41 at one end away from the port, a gear plate 45 is fixedly connected to the outside of the threaded sleeve 44, a threaded rod 43 is fixedly connected to the outer side of the push plate 42, the threaded rod 43 passes through the threaded sleeve 44 and is threadedly connected to the threaded sleeve 44, and a drive motor 46 is fixedly mounted on the outside of the paper cutter 4. The drive motor 46 is coupled to the gear plate 45 through a gear, and the drive motor 46 controls the rotation of the gear plate 45 and the threaded sleeve 44, thereby controlling the push plate 42 to push the waste paper board outward, and only pushes out 1-2 mm each time;

[0032] Furthermore, in the above technical solution, the top of the waste paper trough 41 is set to be open, and a protruding plate 52 is fixedly connected to the end of the rack rod 5 close to the waste paper trough 41. A pressing paper board 53 is installed below the protruding plate 52. The top of the pressing paper board 53 is fixedly connected to a guide slide 54. The guide slide 54 is slidably engaged with the protruding plate 52, and an elastic member is connected between the protruding plate 52 and the pressing paper board 53. The elastic member is a pressure spring. When the rack rod 5 moves downward, the pressing paper board 53 can be used to buffer and press the top of the stacked waste paper boards, thereby preventing the stacked waste paper boards from being misaligned and affecting paper cutting.

[0033] Working principle: By arranging a waste paper trough 41 on the soaking box 1 and installing a cutter 51 that cooperates with the waste paper trough 41 at the end of the rack rod 5, the stacked waste paper boards are stored in the waste paper trough 41, and the sliding control of the pushing plate 42 is achieved by driving the motor 46 to control the rotation of the threaded sleeve 44, thereby realizing the outward pushing control of the waste paper boards. Then, by utilizing the lifting and lowering of the lifting seat 2 and the guidance of the inclined guide rod 8, the cutter 51 is made to slide back and forth at the end of the waste paper trough 41. When the cutter 51 is raised, a small amount of waste paper boards are pushed out. Then, during the subsequent downward movement of the rack rod 5, the cutter 51 cuts the protruding part of the waste paper boards, and the shredded paper falls into the kneading basin 11, waiting for subsequent kneading processing, further improving the functionality and convenience of the equipment. Example

[0034] Based on Example 1, the difference is that Figure 1 and Figure 2 The pulp processing equipment for boxboard production shown in the figure includes a pulping assembly including a rotating shaft 6 rotatably mounted inside a beating cylinder 12, a stirring blade 61 fixedly connected to the outside of the rotating shaft 6, a gear column 62 fixedly connected to the top of the rotating shaft 6, and the gear column 62 and the rack rod 5 are meshed with each other. When the lifting base 2 is lifted and lowered and drives the rack rod 5 to move laterally, it can also drive the rotating shaft 6 to rotate, and then the stirring blade 61 is used to further crush the pulp in the beating cylinder 12, thereby greatly improving the functionality and practicality of the equipment.

[0035] Working principle: By rotating and installing the rotating shaft 6 in the beating cylinder 12, and connecting a stirring blade 61 to the outside of the rotating shaft 6, and fixing a gear column 62 to the top of the rotating shaft 6, the gear column 62 and the rack rod 5 are engaged with each other. While the lifting seat 2 is lifted and lowered to drive the rack rod 5 to move horizontally, it can also drive the rotating shaft 6 to rotate, and then use the stirring blade 61 to further crush the pulp in the beating cylinder 12, which greatly improves the functionality and practicality of the equipment.

[0036] To sum up: by lifting and driving the lifting seat 2, not only the lifting and driving of the kneading head 22 is realized, but also the guiding of the rack rod 5 by the inclined guide rod 8 and the engagement of the rack rod 5 with the gear sleeve 23 are realized, thereby realizing the rotation driving of the kneading head 22, thereby realizing the control of the kneading head 22 to press down and rotate the shredded paper soaked in the kneading basin 11 to perform kneading processing, thereby forming thick pulp. At the same time, the inclined, lifting and sliding movement of the rack rod 5 is used to drive the cutter 51 to move at the end of the waste paper trough 41, and the shredding function of the waste cardboard is also realized. The pressing control of the pressing valve 71 by the lifting and lowering of the rack rod 5 is also realized, and the water supply control of the water diversion pipe 7 is also realized synchronously. At the same time, the movement of the rack rod 5 and the driving of the gear column 62 drive the rotating shaft 6 to rotate in the beating cylinder 12, and the automatic beating function is also realized, thereby greatly improving the functionality and practicality of the equipment and greatly improving the production efficiency of boxboard pulp.
