Description

Technical Field

[0001] This invention relates to the field of pulp board unbundling equipment, specifically a pulp board unbundling device for papermaking. Background Technology

[0002] Pulp board is a type of paperboard made from pulp after dewatering and pressing. It typically weighs over 250 grams per square meter. In the paper industry, pulp boards are mainly produced for ease of transportation. Because many paper mills do not have their own pulping production lines, they need to purchase pulp boards from pulp mills and then break them down into pulp themselves.

[0003] Traditional pulp board unbundling equipment often damages the solidified pulp board during unbundling. This damage makes dissolving the pulp board difficult and hinders the papermaking process, resulting in a lower yield of qualified paper. Furthermore, traditional unbundling equipment leaves pulp board residue on the equipment, which can clog the tracks during subsequent binding, leading to weak binding and ultimately affecting the equipment's efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a pulp board unbundling device for papermaking, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a pulp board unbundling device for papermaking, comprising a base shell, a fixed arm fixedly connected to the top of the base shell, a fixed plate fixedly connected to one side of the fixed arm, a cylinder fixedly connected to the side of the fixed plate away from the fixed arm, a telescopic rod connected to the output end of the cylinder, a push plate fixedly connected to the side of the telescopic rod away from the cylinder, linkage plates fixedly connected to both sides of the push plate, a protective shell fixedly connected to one side of the fixed arm, a support column fixedly connected to one side of the top of the fixed arm, and a second motor fixedly connected to the top of the support column. The activation of the cylinder drives the telescopic rod to push, which in turn moves the push plate, thereby moving the linkage plate. The movement of the linkage plate causes the board to move within the device, resulting in the board sliding within the sliding channel steel, thus unbundling the board. The fixed plate is mainly used to fix the cylinder.

[0006] As a further aspect of the present invention: the protective shell has a plurality of first ventilation holes inside, and a first motor is fixedly connected to the side of the plurality of first ventilation holes. When the first motor is started, it drives the second transmission shaft to rotate, and at the same time drives the first gear to rotate, so that the belt drives the second gear and the third gear to rotate.

[0007] As a further aspect of the present invention: the output end of the first motor is rotatably connected to a second transmission shaft, and a plurality of fan blades are fixedly connected to the outer wall of the second transmission shaft. The plurality of fan blades are evenly distributed around the periphery of the second transmission shaft. The rotation of the second transmission shaft drives the fan blades to rotate in a circle around it. The rotation of the fan blades generates wind power. Through the setting of the first vent and the second vent, the wind power generated by the rotation of the fan blades forms a flow between the first vent and the second vent. After the wind power flows inside, the inside will not be damp, thereby preventing the plate from becoming damp inside.

[0008] As a further aspect of the present invention: a first gear is fixedly connected to the outer wall of the second transmission shaft, and a belt meshes with the outer wall of the first gear. The belt is mainly used to drive the second gear and the third gear to rotate synchronously with the first gear.

[0009] As a further aspect of the present invention: a second gear is provided on one side of the first gear, a first rotating shaft is fixedly sleeved at the axis of the second gear, the end of the first rotating shaft away from the second gear is fixedly sleeved with one of the fan blades, a third gear is provided on the side of the first gear away from the second gear, a second rotating shaft is fixedly sleeved at the axis of the third gear, the end of the second rotating shaft away from the third gear is fixedly sleeved with another fan blade, the outer walls of the second gear and the third gear are meshed with a belt, and the synchronous rotation of the second gear and the third gear causes multiple fan blades to rotate, thereby making the wind force generated by the fan blades more sufficient.

[0010] As a further aspect of the present invention: the fixed arm has a plurality of second ventilation holes inside, the output end of the second motor is rotatably connected to the first transmission shaft, and the side of the first transmission shaft away from the second motor is fixedly connected to a rotating tooth, so that the first transmission shaft is rotated by starting the second motor.

[0011] As a further aspect of the present invention: a plurality of linkage columns are engaged on one side of the rotating tooth, and a rotating column is fixedly connected inside the plurality of linkage columns. The plurality of linkage columns are spirally distributed around the rotating column. The rotation of the first transmission shaft drives the rotating tooth to rotate, and the rotation of the rotating tooth drives the linkage column to rotate.

[0012] As a further aspect of the present invention: a pressure rod is fixedly connected to the bottom of the rotating column, a limit ring seat is slidably connected to the outer wall of the bottom of the pressure rod, support rods are fixedly connected to both sides of the limit ring seat, a flat plate is fixedly connected to the bottom of the support rod, and a pressure groove is opened in the middle of the flat plate. The rotation of the linkage column drives the rotating column to rotate, which in turn causes the rotating column to drive the pressure rod to move upward. After the pressure rod moves upward, the internal plate is reset by the rebound of the limit spring, and the rebound of the plate forms an unbundling effect.

[0013] As a further aspect of the present invention: a fixed rod is fixedly connected to the bottom of the telescopic rod, and a storage box is fixedly connected to the bottom of the fixed rod. An opening and closing plate is provided on one side of the base shell, and a hinge is fixedly connected to the top of the opening and closing plate. The hinge is fixedly connected to the base shell. When the telescopic rod moves, it drives the fixed rod to move, and the movement of the fixed rod drives the storage box to move, thereby causing the storage box to push the opening and closing plate. After pushing the opening and closing plate, it forms an opening and closing function. The hinge is mainly used to connect the base shell and the opening and closing plate.

[0014] As a further aspect of the present invention: a plurality of sliding channel steels are provided on one side inside the fixed arm, a plurality of limiting springs are fixedly connected to the bottom of the plurality of sliding channel steels, and a plurality of plates are slidably connected inside the plurality of sliding channel steels, and the plurality of plates are respectively disposed in the inner cavity of the plurality of sliding channel steels.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. In this invention, by setting up a sliding steel groove, when unbundling the internally bound plates, the second motor rotates in the opposite direction to drive the first transmission shaft to rotate, thereby causing the rotating column to rotate in the direction of the linkage column. This causes the rotating column to drive the lower pressure rod to move upward. After the lower pressure rod moves upward, the internal plates are reset by the rebound of the limit spring. Then, the cylinder drives the telescopic rod to push, and the push of the telescopic rod drives the movement of the push plate, thereby driving the movement of the linkage plate. After the movement of the linkage plate, the internal plates can be unbundled in an orderly manner, while avoiding damage caused by the solidification of the pulp plate, thus increasing the practicality of this invention.

[0017] 2. In this invention, the storage box allows the board to be moved when it is unbundled. This movement is facilitated by the reset of the limit spring, which also helps to shake off dust and excess debris. After the dust and debris are removed, the bottom storage box collects them. As the board is unbundled, the movement of the telescopic rod moves the fixed rod, causing the storage box to move as well. This outward movement of the storage box allows for the removal and cleaning of any remaining items inside. By collecting and processing the internal residue, blockage of the sliding channel steel is avoided.

[0018] 3. In this invention, the fan blades are designed so that starting the first motor drives the second transmission shaft to rotate, which in turn drives the first gear to rotate. This causes the belt to drive the second and third gears to rotate. The rotation of the second transmission shaft causes the fan blades to rotate in a circle around the shaft. The rotation of the fan blades generates wind. The first and second vents allow the wind generated by the fan blades to circulate between them. This internal airflow prevents moisture from forming inside the fan blades, thus avoiding dampness and improving the efficiency of the invention. Attached Figure Description

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example 1:

[0030] Please see Figures 1-8 In this embodiment of the invention, a pulp board unbundling device for papermaking includes a base shell 4. A fixed arm 31 is fixedly connected to the top of the base shell 4. A fixed plate 5 is fixedly connected to one side of the fixed arm 31. A cylinder 6 is fixedly connected to the side of the fixed plate 5 away from the fixed arm 31. A telescopic rod 19 is connected to the output end of the cylinder 6. A push plate 20 is fixedly connected to the side of the telescopic rod 19 away from the cylinder 6. Linkage plates 21 are fixedly connected to both sides of the push plate 20. A protective shell 3 is fixedly connected to one side of the fixed arm 31. The top of the fixed arm 31... A support column 15 is fixedly connected to one side of the part, and a second motor 14 is fixedly connected to the top of the support column 15. The start of the cylinder 6 drives the telescopic rod 19 to push, and the push of the telescopic rod 19 drives the push plate 20 to move, thereby driving the linkage plate 21 to move. The movement of the linkage plate 21 drives the plate body 22 to move inside the invention, thereby causing the plate body 22 to slide within the sliding channel steel 32, thus forming an unbinding effect on the plate body 22. The fixing plate 5 is mainly used to fix the cylinder 6.

[0031] Furthermore, the protective shell 3 has multiple first ventilation holes 2 inside, and a first motor 1 is fixedly connected to the side of the multiple first ventilation holes 2.

[0032] In this embodiment, by starting the first motor 1 to drive the second transmission shaft 29 to rotate, the first gear 25 is driven to rotate, thereby causing the belt 28 to drive the second gear 26 and the third gear 27 to rotate.

[0033] Example 2:

[0034] Please see Figures 1-8 In this embodiment of the invention, a second drive shaft 29 is rotatably connected to the output end of a first motor 1. A plurality of fan blades 30 are fixedly connected to the outer wall of the second drive shaft 29. The fan blades 30 are evenly distributed around the periphery of the second drive shaft 29. The rotation of the second drive shaft 29 drives the fan blades 30 to rotate in a circular motion around its center. A first gear 25 is fixedly connected to the outer wall of the second drive shaft 29. A belt 28 meshes with the outer wall of the first gear 25. A second gear 26 is disposed on one side of the first gear 25. A first rotating shaft 37 is fixedly sleeved at the axis of the second gear 26. The end of the first rotating shaft 37 away from the second gear 26 is fixedly sleeved with one of the fan blades 30. A third gear 27 is disposed on the side of the first gear 25 away from the second gear 26. A second rotating shaft 36 is fixedly sleeved at the axis of the third gear 27. The end of the second rotating shaft 36 away from the third gear 27 is fixedly sleeved with the third gear 27. Another fan blade 30 is fixedly sleeved with the first fan blade. The outer walls of the second gear 26 and the third gear 27 are meshed with the belt 28. After the second gear 26 and the third gear 27 rotate synchronously, the multiple fan blades 30 rotate, thereby making the wind force generated by the fan blades 30 more sufficient. The fixed arm 31 has multiple second ventilation holes 34 inside. The output end of the second motor 14 is rotatably connected to the first drive shaft 13. The side of the first drive shaft 13 away from the second motor 14 is fixedly connected to the rotating gear 12. The first drive shaft 13 is rotated by starting the second motor 14. The rotating gear 12 is meshed with multiple linkage columns 10 on one side. The multiple linkage columns 10 are fixedly connected to the rotating columns 11 inside. The multiple linkage columns 10 are spirally distributed around the rotating columns 11. The rotation of the first drive shaft 13 drives the rotating gear 12 to rotate, and the rotation of the rotating gear 12 drives the linkage columns 10 to rotate.

[0035] In this embodiment, the fan blade 30 generates wind power by rotating. The first vent 2 and the second vent 34 are provided to allow the wind power generated by the fan blade 30 to circulate between the first vent 2 and the second vent 34. After the wind power circulates inside, the inside will not become damp, thus preventing the plate 22 from becoming damp inside. The belt 28 is mainly used to drive the second gear 26 and the third gear 27 to rotate synchronously with the first gear 25.

[0036] Example 3:

[0037] Please see Figures 1-8 In this embodiment of the invention, a pressing rod 8 is fixedly connected to the bottom of the rotating column 11. A limiting ring seat 7 is slidably connected to the outer wall of the bottom of the pressing rod 8. Support rods 9 are fixedly connected to both sides of the limiting ring seat 7. A flat plate 35 is fixedly connected to the bottom of the support rod 9. A pressing groove 16 is opened in the middle of the flat plate 35. The rotation of the linkage column 10 drives the rotating column 11 to rotate, thereby causing the rotating column 11 to drive the pressing rod 8 to move upward. After the pressing rod 8 moves upward, the inner plate 22 is reset by the rebound of the limiting spring 33. After the plate 22 rebounds, it is released. The telescopic rod 19 is fixedly connected to a fixed rod 23 at its bottom, and a storage box 24 is fixedly connected to the bottom of the fixed rod 23. An opening and closing plate 18 is provided on one side of the base shell 4, and a hinge 17 is fixedly connected to the top of the opening and closing plate 18. The hinge 17 is fixedly connected to the base shell 4. A plurality of sliding channel steels 32 are provided on one side inside the fixed arm 31. A plurality of limiting springs 33 are fixedly connected to the bottom of each of the plurality of sliding channel steels 32. A plurality of plates 22 are slidably connected inside the plurality of sliding channel steels 32, and the plurality of plates 22 are respectively arranged in the inner cavity of the plurality of sliding channel steels 32.

[0038] In this embodiment, the movement of the telescopic rod 19 causes the fixed rod 23 to move, and the movement of the fixed rod 23 causes the storage box 24 to move, thereby causing the storage box 24 to push the opening and closing plate 18. After pushing the opening and closing plate 18, it forms an opening and closing function. The hinge 17 is mainly used to connect the base shell 4 and the opening and closing plate 18.

[0039] Working principle:

[0040] First, the invention is placed in the desired location using the base shell 4. Then, the plate 22 to be transported is slid into the invention via the sliding channel steel 32. Next, the second motor 14 is activated, driving the first transmission shaft 13 to rotate. The rotation of the first transmission shaft 13 drives the rotating gear 12 to rotate, which in turn drives the linkage column 10 to rotate. The rotation of the linkage column 10 drives the rotating column 11 to rotate, simultaneously causing the downward pressure rod 8 to press down. The downward pressure of the downward pressure rod 8 effectively secures the plate 22 inside the invention, thus binding the plate 22. The fan blades 30, when activated, drive the second transmission shaft 29... While rotating, the first gear 25 is driven to rotate, which in turn causes the belt 28 to drive the second gear 26 and the third gear 27 to rotate. The rotation of the second transmission shaft 29 drives the fan blade 30 to rotate in a circle around it. The rotation of the fan blade 30 generates wind. The first vent 2 and the second vent 34 allow the wind generated by the rotation of the fan blade 30 to circulate between them. This airflow prevents moisture from forming inside the fan blade 22, thus avoiding dampness inside the fan blade 22 and improving the efficiency of the invention. Furthermore, the storage box 24 allows for convenient storage of the fan blade 22. During unbundling, the return of the limit spring 33 causes the plate 22 to move, which also generates dust and shakes off excess debris. After the dust and debris are removed, the bottom storage box 24 collects them. Simultaneously, the movement of the telescopic rod 19 moves the fixing rod 23, causing the storage box 24 to move as well. This outward movement of the storage box 24 allows for the removal of any remaining debris and cleaning of the box itself. Collecting and processing the internal residue prevents blockage of the sliding channel steel 32. The sliding channel steel 32 effectively holds the internally bound plates... When the body 22 is unbundled, the second motor 14 rotates in the opposite direction, driving the first transmission shaft 13 to rotate. This causes the rotating column 11 to rotate in the opposite direction via the linkage column 10. The rotating column 11 then causes the lower pressure rod 8 to move upward. After the lower pressure rod 8 moves upward, the inner plate 22 is reset by the rebound of the limit spring 33. The cylinder 6 is then activated, driving the telescopic rod 19 to push. The push of the telescopic rod 19 drives the push plate 20 to move, which in turn drives the linkage plate 21 to move. After the linkage plate 21 moves, the inner plate 22 can be unbundled in an orderly manner, while avoiding damage caused by the solidification of the pulp board, thus increasing the practicality of the invention.

[0041] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
