Description

Technical Field

[0001] The present invention relates to the technical field of papermaking, in particular to automatic feeding equipment for a papermaking machine. Background Art

[0002] A papermaking machine is a device used to produce paper. It mixes cellulose fibers with water and filters, compacts, and dries them to form paper. Its working process typically includes pulp preparation, forming and filtering, calendering, drying, and reeling. Pulp filtering and calendering involve filtering the pulp to obtain formed fibers and then flattening them to make them smoother and flatter. The effects of filtering and calendering directly affect the quality of the subsequent paper.

[0003] Paper production generally adopts assembly line operation, and pulp is continuously sent by conveying equipment to the filtration area and calendering area for corresponding processing. However, the following problems still exist in the process of pulp feeding and conveying: 1. The range of movement in pulp conveying is generally fixed, and the laying width of the pulp cannot be flexibly changed according to the required width of the paper, and the satisfaction of the demand for producing paper of different sizes is low.

[0004] 2. Because the pulp has a certain fluidity, during the transportation process, the upper fibers in the pulp have higher fluidity than the lower fibers. The single flow can easily cause the lower fibers to precipitate or accumulate, blocking the subsequent pulp transportation. At the same time, it can easily lead to uneven and uneven distribution of pulp fibers after filtration.

[0005] Therefore, in order to solve the problems existing in the process of pulp feeding and conveying, the present invention provides an automatic feeding device for a papermaking machine. Summary of the Invention

The pulleys 117 are connected by a belt 118 for transmission, and an adjusting handle is installed at the front end of the pulley 117 on the left.

[0033] See also Figure 1 、 Figure 3 、 Figure 4 ,and Figure 7 The pulp filtering area 12 is arranged at the upper end of the filtering groove 112. The pulp filtering area 12 includes a slapping plate 121 arranged at the upper left end of the filtering groove 112. A tooth plate 122 is installed on the upper end of the slapping plate 121. A guide sleeve 123 is provided on the tooth plate 122, which is symmetrical up and down. The guide sleeve 123 is slidably connected to the tooth plate 122. A rectangular plate 124 is installed on the upper end of the fixed plate 111 at the rear end of the tooth plate 122. The guide sleeve 123 and the rectangular plate 124 are fixedly connected by a connecting plate. A half gear 125 is provided at the right end of the tooth plate 122. The tooth plate 122 is meshed with the half gear 125. A fixed rod 126 is installed at the center of the half gear 125. A center rod 127 rotatably connected to the rectangular plate 124 is fixedly installed at the left end of the fixed rod 126. A sliding groove is provided in the middle of the fixed rod 126. A Z-shaped connecting frame 128 is provided on the rear side of the fixed rod 126. The horizontal section on the front side of the Z-shaped connecting frame 128 is slidably connected to the sliding groove. The horizontal section on the rear side of the Z-shaped connecting frame 128 is connected to the output shaft of the drive motor 129. The drive motor 129 is installed at the front end of the rectangular plate 124 through a support.

[0034] In the process of feeding and conveying the pulp, the existing pulping box is first used to control the mixed pulp to flow evenly and slowly from the left end of the belt conveyor 1 to the upper end surface of the nylon mesh conveyor belt 11. The baffle 114 on the left side of the nylon mesh conveyor belt 11 effectively prevents the pulp from overflowing from the left end of the belt conveyor 1, so that the pulp is located between the two adjusting plates 113 at the front and rear ends of the upper end of the nylon mesh conveyor belt 11. When it is necessary to filter to obtain pulp fibers of different widths, the adjusting handle can be manually rotated before feeding the pulp to drive the pulley 117 on the left to rotate synchronously through the adjusting handle. The pulley 117 on the right is kept in synchronous movement with the pulley 117 on the left through the belt 118. The pulleys 117 on the left and right sides drive the bidirectional screw The rods 116 rotate synchronously, so that the control plates on the front and rear sides drive the adjustment plates 113 on the front and rear sides to move synchronously in opposite directions along the bidirectional screw 116 to appropriate positions. During this process, the adjustment plates 113 on the front and rear sides slide along the upper surface of the nylon mesh conveyor belt 11. The adjustment plates 113 are in close contact with the nylon mesh conveyor belt 11 to ensure that the pulp does not flow out. By changing the distance between the adjustment plates 113, the laying width of the subsequent pulp on the nylon mesh conveyor belt 11 is changed, so that pulp fibers of different widths can be obtained after filtration, and the width of the subsequently generated paper can be effectively controlled to meet the requirements of producing paper of different sizes in the papermaking process, flexibly adapt to the production of different types of paper, and increase the practicality of the equipment.

[0035] During the process of the nylon mesh conveyor belt 11 conveying the pulp to the pulp filtering area 12, the fixed plate 111 between the nylon mesh conveyor belts 11 is in sliding contact with the nylon mesh conveyor belts 11. At this time, the liquid in the pulp will not flow downward through the nylon mesh conveyor belt 11. The belt conveyor 1 continuously conveys the pulp to the right through the nylon mesh conveyor belt 11. When the pulp follows the nylon mesh conveyor belt 11 to the pulp filtering area 12, the pulp is located at the upper end of the filtering groove 112. At this time, the liquid in the pulp can flow through the nylon mesh conveyor belt 11. The mesh conveyor belt 11 flows downward from the filter groove 112, and is filtered by the nylon mesh conveyor belt 11 so that the fibers in the pulp remain on the upper end surface of the nylon mesh conveyor belt 11, while the liquid in the pulp flows to the existing waste liquid collection area through the filter groove 112. At the same time as the pulp enters the left end of the pulp filtration area 12, the drive motor 129 drives the horizontal section on the rear side of the Z-shaped connecting frame 128 to rotate the Z-shaped connecting frame 128 as a whole. During this process, the horizontal section on the front side of the Z-shaped connecting frame 128 moves along the sliding groove at the same time. The tooth plate 122 is meshed with the tooth plate 122 during the up and down swinging process, so that the tooth plate 122 moves up and down along the guide sleeve 123, and the tooth plate 122 drives the slapping plate 121 at its lower end to move up and down synchronously. The slapping plate 121 continuously and gently taps the pulp, and the pulp is continuously and gently tapped by the slapping plate 121 and oscillates, so that the fibers and liquid in the pulp are in an active state, accelerating the flow between the upper and lower layers of the pulp, evenly dispersing the fibers in the pulp, and quickly filtering out the liquid in the pulp, so as to avoid the pulp under the conveying flow only flowing to the right, causing the lower layer of fibers to easily precipitate or accumulate, blocking the subsequent conveying of the pulp, and causing the filtered pulp fibers to be unevenly distributed and uneven. After passing through the pulp filtering area 12, a wet pulp fiber layer remains on the upper surface of the nylon mesh conveyor belt 11.

[0036] See also Figure 1 、 Figure 3 and Figure 6The calendering area 2 includes a calendering conveyor 21 arranged at the right end of the belt conveyor 1. The calendering conveyor 21 consists of a calendering conveying surface 211 and a fixed frame. The left end of the calendering conveying surface 211 is in contact with the right end of the nylon mesh conveyor belt 11. A drying box 22 is provided on the upper right end of the fixed frame. Extrusion rollers 212 are symmetrically provided on the upper left end of the fixed frame. The calendering conveying surface 211 is located between the extrusion rollers 212. The extrusion rollers 212 at the upper end are rotatably installed between the inner walls of the front and rear vertical sections of the inverted profile. The extrusion rollers 212 at the lower end are symmetrically provided with the fixed frame. The fixed frame is rotatably connected, and a vertical bevel gear 213 is installed at the front end of the extrusion roller 212. A rotating column 214 is provided at the front end of the vertical bevel gear 213. A horizontal bevel gear 215 that is symmetrical up and down is sleeved on the rotating column 214. The horizontal bevel gear 215 is meshed with the corresponding vertical bevel gear 213. A horizontal plate 216 is installed at the front end of the fixed frame at the lower end of the rotating column 214. The lower end of the rotating column 214 rotates through the horizontal plate 216 and is connected to the output shaft of the vertical motor 217. The vertical motor 217 is installed at the lower end of the horizontal plate 216 through an L-shaped plate.

[0037] The wet pulp fiber layer is continuously conveyed to the right along the nylon mesh conveyor belt 11. When the pulp fiber layer is conveyed to the right end of the belt conveyor 1, the operator cooperates with the calendering conveyor 21 to smoothly move the right end of the pulp fiber layer to the calendering conveying surface 211, and then the calendering conveying surface 211 is connected to continue conveying the pulp fiber layer to the right. During this process, the pulp fiber layer approaches the direction of the squeezing roller 212, and the vertical motor 217 drives the upper and lower horizontal bevel gears 215 to rotate synchronously in the same direction through the rotating column 214. The upper and lower vertical bevel gears 213 are respectively connected to the upper and lower horizontal bevel gears 214. The wheels 215 mesh and rotate synchronously in opposite directions, causing the upper and lower squeezing rollers 212 to drive synchronously in opposite directions. The squeezing roller 212 at the lower end is pressed against the squeezing roller 212 at the upper end via the calendering conveyor surface 211, so that the pulp fiber layer on the calendering conveyor surface 211 is rolled by the upper and lower squeezing rollers 212. This rolling squeezes out the residual liquid in the pulp fiber layer and initially solidifies the pulp fiber layer, making the pulp fibers evenly and compactly distributed. The residual liquid flows to the existing waste liquid collection area, which facilitates the subsequent rapid and efficient drying of the pulp fibers. The squeezed pulp fiber layer is further transported to the right by the calendering conveyor surface 211 to the drying box 22 for drying. The dried pulp fibers can then be collected for subsequent paper rolls.

[0038] See also Figure 1 、 Figure 3 、 Figure 4 and Figure 5The front ends of the two front and rear adjustment plates 113 are both provided with a guide groove 119 located on the right side of the pulp filtering area 12. A number of leveling rollers 131 are slidably connected between the guide grooves 119. The leveling rollers 131 are rotatably connected between the two vertical sections of the same inverted U-shaped plate 132. A rack 133 is installed at the left end of the horizontal section of the inverted U-shaped plate 132. Support rods 134 are installed at the front and rear ends of the rack 133. The support rods 134 are slidably connected to the fixed plate 111. A transmission gear 135 is provided on the upper end of the rack 133 and is mounted on the horizontal section on the rear side of the Z-shaped connecting frame 128. The rack 133 is meshed with the transmission gear 135.

[0039] In the process of driving the Z-shaped connecting frame 128 to rotate by the driving motor 129 so that the beating plate 121 beats the pulp, the center rod 127 drives the transmission gear 135 to synchronously reciprocate and deflect forward and reverse, and the rack 133 engages with the transmission gear 135 and moves back and forth left and right. The rack 133 drives the inverted U-shaped frame to make the leveling roller 131 slide back and forth along the guide groove 119. At the same time, the support rods 134 on the front and rear sides of the rack 133 slide left and right along the fixed plate 111. The rack 133 is supported by the support rods 134 to provide support for the stable reciprocating movement of the rack 133 and the inverted U-shaped frame. In the process of the leveling roller 131 sliding back and forth along the guide groove 119, the leveling roller 131 contacts and scrapes the pulp fiber layer that has just been filtered, pre-leveling the pulp fiber layer, increasing the flatness and uniformity of the pulp fibers, and at the same time performing the initial pressing and removal of residual moisture in the pulp fiber layer.

[0040] See also Figure 4 and Figure 5 A pre-pressing roller 136 is rotatably connected between the two mounting plates 115 on the right side. The front ends of the pre-pressing roller 136 and the transmission roller on the right side of the belt conveyor 1 are both equipped with spur gears 137, and the spur gears 137 are meshed with each other.

[0041] The leveled pulp fibers gradually reach the right end of the belt conveyor 1 under the transportation of the nylon mesh conveyor belt 11. During this process, as the drive roller on the right side of the belt conveyor 1 rotates, the spur gear 137 at its front end rotates synchronously. The spur gear 137 at the front end of the pre-pressing roller 136 and the spur gear 137 at the front end of the drive roller rotate synchronously in opposite directions through meshing. While the drive roller rotates clockwise to drive the nylon mesh conveyor belt 11 to the right, the pre-pressing roller 136 rotates counterclockwise synchronously. During the rotation of the pre-pressing roller 136, the pulp fibers reaching the right end of the belt conveyor 1 are rolled and squeezed, and the excess water remaining in the pulp fibers is further squeezed out and flows to the existing waste liquid collection area. By squeezing out the excess water remaining in the pulp fibers, the pulp fibers are solidified for the second time, so that the pulp fibers are condensed together to form a stable whole and move to the calendering area 2, which is conducive to subsequent calendering treatment. At the same time, the subsequent calendering effect and efficiency are improved through pre-double solidification and leveling.

[0042] See also Figure 6 The horizontal bevel gear 215 located at the bottom is fixedly connected to the rotating column 214, and the horizontal bevel gear 215 located at the top is fixedly sleeved on the outside of the circular sleeve 138. The inner ring wall of the circular sleeve 138 and the rotating column 214 are splined. The circular sleeve 138 is installed on the movable plate 139, and the movable plate 139 is installed on the vertical section of the inverted plate. An electric push rod 141 is connected between the movable plate 139 and the horizontal plate 216.

[0043] When the required paper thickness changes, the movable plate 139 and the inverted plate can be pushed up and down by the electric push rod 141. The movable plate 139 cooperates with the spline on the rotating column 214 through the circular sleeve 138, so that the circular sleeve 138 drives the horizontal bevel gear 215 connected to it to slide up and down along the rotating column 214, so that the horizontal bevel gear 215 located above and the vertical bevel gear 213 with which it meshes keep synchronous movement with the squeezing roller 212. By changing the distance between the upper and lower squeezing rollers 212, the requirements for producing paper of different thicknesses can be met.

[0044] See also Figure 7 The front and rear ends of the slapping plate 121 are symmetrically and slidingly connected with an auxiliary plate 143. A plurality of sockets are evenly arranged on the upper end of the auxiliary plate 143. A docking hole is opened on the upper end of the slapping plate 121, and a round bolt is inserted between the docking hole and the corresponding socket.

[0045] After the distance between the front and rear adjustment plates 113 is adjusted to the required paper width, before conveying the pulp, the round bolt is removed and the auxiliary plate 143 is moved toward or away from each other to adjust the total front and rear length of the auxiliary plate 143 and the slapping plate 121 according to the distance between the adjustment plates 113. Then the round bolt is installed to fix the auxiliary plate 143 again to ensure that the slapping plate 121 and the auxiliary plate 143 perform the slapping function.

[0046] See also Figure 4 and Figure 5 A scraper 144 tilted to the upper left is installed on the lower right end of the fixed part of the belt conveyor 1, and the upper end of the scraper 144 is in sliding contact with the nylon mesh conveyor belt 11.

[0047] After the nylon mesh conveyor belt 11 continuously conveys the initially formed pulp fiber layer to the calendering conveying surface 211, the scraper 144 at the right end of the belt conveyor 1 scrapes and contacts the nylon mesh conveyor belt 11 after it separates from the pulp fiber layer, removing a small amount of fiber remaining on the nylon mesh conveyor belt 11, ensuring that the nylon mesh conveyor belt 11 is in a clean state when it contacts new pulp, better completing the transportation and filtration of the pulp, and facilitating the subsequent forming of the pulp fibers.

[0048] See also Figure 4 and Figure 5 A placement plate 145 is installed on the lower side of the right end of the fixed part of the belt conveyor 1, and a collection frame 146 located below the scraper 144 is overlapped on the upper end of the placement plate 145.

[0049] After the scraper 144 scrapes off the small amount of fiber remaining on the nylon mesh conveyor belt 11, the fiber will enter the collection frame 146 along the inclined scraper 144, and the residual fiber will be collected by the collection frame 146. When there are enough residual fibers in the collection frame 146, the collection frame 146 can be removed from the placement plate 145 for unified treatment, avoiding environmental pollution while recycling these fibers.

[0050] Working principle of the present invention: In the process of feeding and conveying pulp, the existing pulping box is first used to control the mixed pulp to flow evenly and slowly from the left end of the belt conveyor 1 to the upper end surface of the nylon mesh conveyor belt 11. When it is necessary to filter and obtain pulp fibers of different widths, the adjustment handle can be manually rotated before feeding the pulp. The adjustment handle drives the pulley 117 on the left to rotate synchronously. The pulley 117 on the right keeps synchronous movement with the pulley 117 on the left through the belt 118. The pulleys 117 on the left and right sides drive the bidirectional screw 116 to rotate synchronously, so that the control plates on the front and rear sides drive the adjustment plates 113 on the front and rear sides to move synchronously in opposite directions along the bidirectional screw 116 to the appropriate position. , the belt conveyor 1 continuously conveys the pulp to the right through the nylon mesh conveyor belt 11. When the pulp follows the nylon mesh conveyor belt 11 to the pulp filtering area 12, the pulp is located at the upper end of the filtering groove 112. At this time, the liquid in the pulp can pass through the nylon mesh conveyor belt 11 and flow downward from the filtering groove 112. The fibers in the pulp are filtered by the nylon mesh conveyor belt 11 so that they remain on the upper end surface of the nylon mesh conveyor belt 11, and the liquid in the pulp flows to the existing waste liquid collection area through the filtering groove 112. When the pulp enters the left end of the pulp filtering area 12, the driving motor 129 drives the horizontal section on the rear side of the Z-shaped connecting frame 128 to rotate the Z-shaped connecting frame 128 as a whole. During this process, the Z-shaped connecting frame 1 The horizontal section on the front side of 28 slides synchronously along the sliding groove, thereby driving the fixed rod 126 to swing up and down around the center rod 127 at its left end, and the fixed rod 126 drives the half gear 125 to swing up and down synchronously. During the up and down swinging process of the half gear 125, it engages with the tooth plate 122, so that the tooth plate 122 moves up and down along the guide sleeve 123, and the tooth plate 122 drives the slapping plate 121 at its lower end to move up and down synchronously, and the wet pulp fiber layer continues to be transported to the right along the nylon mesh conveyor belt 11. When the pulp fiber layer is transported to the right end of the belt conveyor 1, the operator cooperates with the calendering conveyor 21 to make the right end of the pulp fiber layer smoothly move to the calendering conveying surface 211, and then the calendering conveying surface 211 is connected to continue The pulp fiber layer continues to be transported to the right. During this process, the pulp fiber layer approaches the direction of the squeezing roller 212. The vertical motor 217 drives the upper and lower horizontal bevel gears 215 to rotate synchronously in the same direction through the rotating column 214. The upper and lower vertical bevel gears 213 are respectively engaged with the upper and lower horizontal bevel gears 215 and rotate synchronously in opposite directions, so that the upper and lower squeezing rollers 212 are synchronously driven in opposite directions. The squeezing roller 212 at the lower end is pressed against the squeezing roller 212 at the upper end through the calendering conveying surface 211. The squeezed pulp fiber layer continues to be transported to the right through the calendering conveying surface 211 to the drying box 22 for drying treatment. The dried pulp fiber can be collected for subsequent paper rolls.
