Description

Technical Field

[0001] This application relates to the technical field of pulp bale conveying equipment, and in particular to a pulp bale conveying system. Background Technology

[0002] Pulp bags are usually made up of several pulp slabs stacked together. To facilitate the transport of pulp bags, they are usually bundled with wire. Each pulp bag requires three to four wires for binding. Six to eight pulp bags are then stacked together to form a pulp bag stack. Each stack of pulp bags is then bound together with seven to eight wires. The wires binding the pulp bags must be removed before they enter the pulp dispensing equipment, otherwise the equipment will be damaged.

[0003] Currently, related pulp bag conveying systems include, for example, Chinese Patent Publication No. CN102991780B, "Pulp Bag Conveying System," which discloses a pulp bag conveying system. The system includes a conveyor belt for transporting pulp bags to the top of a pulp trough, allowing the pulp bags to fall into the pulp trough for pulp dispersal, a wire removal device installed on the conveyor belt, and an iron remover installed between the conveyor belt and the pulp trough. The iron remover is used to magnetically attract the iron wires on the pulp bags before they fall into the pulp trough.

[0004] In related technologies, when the slurry bag passes through the magnetic separator, it slides over the separator at an angle. Because the slurry bag is square in shape, the magnetic separator can only magnetically attract the iron wires on the side of the slurry bag closest to the magnetic separator. Iron wires may still remain on the side of the slurry bag away from the magnetic separator, which can easily cause iron wires to get mixed into the slurry dispersing equipment and damage the equipment. Summary of the Invention

[0005] To further improve the removal of iron wires from the pulp bag, this application provides a pulp bag conveying system.

[0006] The slurry bag conveying system provided in this application adopts the following technical solution:

[0007] A pulp bag conveying system includes a pulp trough and a conveying mechanism for conveying pulp bags into the pulp trough. The conveying mechanism includes a conveyor belt inclined upward toward the pulp trough. The conveying mechanism also includes a frame and a plurality of drive rollers for receiving pulp bags. The plurality of drive rollers are rotatably mounted on the frame. The conveying mechanism also includes a drive assembly for driving the drive rollers to rotate toward the pulp trough. A plurality of iron removal rollers capable of magnetically attracting iron wires are also rotatably mounted on the frame. The frame is located between the conveyor belt and the opening of the pulp trough. A flipping mechanism is provided above the drive rollers. The flipping mechanism includes a flipping rod and a first flipping assembly that causes the flipping rod to tumble the pulp bag. The flipping rod can abut against the lower edge of the pulp bag on the side near the pulp trough.

[0008] By adopting the above technical solution, when the pulp bag is conveyed by the conveyor belt, the tied iron wire can be cut manually or by shearing equipment. When the pulp bag is conveyed to the drive roller, the iron removal roller attracts the iron wire on the pulp bag, which can separate the iron wire. At the same time, as the pulp bag is conveyed on the drive roller, the flipping mechanism flips the pulp bag so that each side of the pulp bag can contact the iron removal roller, further improving the removal effect of the iron wire remaining on the pulp bag. In addition, the flipping mechanism makes the pulp bag roll towards the pulp distribution trough, which further improves the conveying efficiency of the pulp bag.

[0009] Optionally, the first tilting assembly includes a first rocker arm rotatably mounted on the side of the frame near the slurry trough. A strike plate is fixed to the middle section of the first rocker arm to impact the slurry supply bag when it falls into the slurry trough. A connecting rod is rotatably mounted to the end of the first rocker arm away from the frame. The connecting rod is parallel to the length direction of the frame. A rotating rod is rotatably mounted on the connecting rod. The end of the rotating rod away from the connecting rod is fixedly connected to the tilting arm. A side plate is also vertically fixed to the transmission frame. A fixing plate is fixed to the end of the side plate away from the first rocker arm. The middle section of the rotating rod is rotatably connected to the side plate. A rocker spring is fixed to the end of the connecting rod away from the first rocker arm. The end of the rocker spring away from the connecting rod is fixed to the fixing plate.

[0010] By adopting the above technical solution, the pulp bale moves towards the pulp distribution trough under the transmission action of the drive roller. The pulp bale that is close to the pulp distribution trough will automatically hit the impact plate, causing the first rocker arm to rotate towards the pulp distribution trough. Thus, under the drive of the connecting rod, the rotating rod rotates, and the flipping rod gives the pulp bale a flipping force, causing the pulp bale to flip on the frame. This is beneficial for the iron removal roller to remove iron from the pulp bale better, and reduces the interference caused by iron wire mixed in during the subsequent pulp distribution in the pulp distribution trough. After the flipping rod completes one flip, the flipping spring resets, so that the flipping rod can continue to flip the next pulp bale.

[0011] Optionally, there may be multiple flip rods, which are installed at intervals on the mounting plate.

[0012] By adopting the above technical solution, multiple flipping rods can be set up to achieve multiple flipping operations on the same pulp bag, ensuring better removal of iron wires from the pulp bag. During the tumbling process, the vibration of the pulp bag is more conducive to the falling off of iron wires, and the multiple flipping of the pulp bag helps to increase the transmission speed of the pulp bag on the drive roller, thereby improving the overall production efficiency.

[0013] Optionally, the flipping mechanism further includes a push rod and a second flipping assembly that causes the push rod to flip the pulp bag. The second flipping assembly is disposed opposite to the first flipping assembly, and the push rod abuts against the upper edge of the side of the pulp bag.

[0014] By adopting the above technical solution, a second flipping component is set to push the pulp bag, which further improves the tumbling effect of the pulp bag, allowing the side of the pulp bag to better contact the iron removal roller, and at the same time improves the conveying efficiency of the pulp bag.

[0015] Optionally, the second flipping assembly includes a second rocker arm, which is rotatably mounted on the frame. The middle section of the second rocker arm is fixedly connected to the end of the impact plate away from the first rocker arm. An installation rod is rotatably mounted on the second rocker arm, and a pull rod is rotatably mounted on the end of the installation rod away from the second rocker arm. The rotation axes at both ends of the installation rod are perpendicular to each other. An insertion rod is rotatably mounted on the end of the pull rod away from the installation rod. The end of the insertion rod near the frame is rotatably connected to the frame. A first disc is also rotatably mounted on the frame. The circumferential surface of the first disc has multiple slots. The end of the insertion rod away from the frame can be inserted into the slots. A return spring is also fixed on the side of the insertion rod near the first disc to automatically press the insertion rod against the circumferential surface of the first disc. A second disc is also coaxially fixed on the first disc. There are multiple push rods, which are evenly spaced and fixed on the circumferential surface of the second disc. When the insertion rod is inserted into the slot, the pulp bag is located between two adjacent push rods.

[0016] By adopting the above technical solution, when the second swing rod swings, under the action of the mounting plate and the pull rod, the insertion rod moves away from the slot and pushes the rod to rotate on the second disc, thereby achieving the effect of pushing the pulp bag to flip. The return spring makes the insertion rod press against the circumferential surface of the first disc and finally lock into the slot, thereby achieving the effect of flipping the next pulp bag.

[0017] Optionally, the height between the first disk and the second disk is adjustable. An adjusting column is fixed on the first disk, and an adjusting cylinder is fixed at the center of the second disk. The axis of the adjusting column and the adjusting cylinder are on the same straight line, and the adjusting column and the adjusting cylinder are inserted into each other. A threaded hole is opened through the side wall of the adjusting cylinder, and a bolt is threaded into the threaded hole. The bolt passes through the threaded hole and abuts against the adjusting column.

[0018] By adopting the above technical solution, the height position of the push rod can be adjusted by adjusting the distance between the first and second discs, so that it can push and flip pulp bags of different specifications.

[0019] Optionally, the frame is inclined downwards from the end furthest from the slurry trough toward the end closest to the slurry trough.

[0020] By adopting the above technical solution, the frame is tilted, which helps to promote the impact of the pulp bag on the impact plate, causing the first rocker arm and the second rocker arm to rotate towards the side closer to the pulp trough, thereby promoting the flipping of the pulp bag by the flipping mechanism.

[0021] Optionally, there are multiple iron removal rollers and multiple drive rollers, and the iron removal rollers and drive rollers are alternately installed on the frame. A magnet column is coaxially inserted inside the iron removal roller, and the iron removal roller has a plastic shell.

[0022] By adopting the above technical solution, the iron removal roller and the transmission roller are set alternately, which ensures both the conveying effect on the pulp bag and the iron removal effect on the pulp bag. When the number of iron wires adsorbed on the surface of the iron removal roller is too large, the iron wires on the iron removal roller can be cleaned by horizontally pulling out the magnetic column.

[0023] Optionally, a collection hopper for receiving iron wire is placed directly below the iron removal roller and the drive roller.

[0024] By adopting the above technical solution, the magnetic force of the iron removal roller is eliminated by pulling out the magnetic column, and the iron wire will automatically fall into the collection hopper for easy subsequent cleaning.

[0025] Optionally, the drive assembly includes a sprocket coaxially fixed to one end of the drive roller, with a chain meshing between adjacent sprockets, and a motor coaxially fixed to the end of the drive roller away from the sprocket.

[0026] By adopting the above technical solution, the motor drives one of the transmission rollers to rotate. Under the transmission action of the sprocket and chain, multiple transmission rollers rotate simultaneously toward the direction of the pulp trough, thereby realizing the conveying of the pulp bag.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. During the conveyor belt transport of pulp bags, the binding wires can be cut manually or with shearing equipment. When the pulp bag is conveyed to the drive roller, the iron removal roller attracts the iron wires on the pulp bag, thus separating the iron wires. At the same time, as the pulp bag is conveyed on the drive roller, the turning mechanism turns the pulp bag so that each side of the pulp bag can contact the iron removal roller, further improving the removal effect of residual iron wires on the pulp bag. In addition, the turning mechanism makes the pulp bag roll towards the pulp trough, further improving the conveying efficiency of the pulp bag.

[0029] 2. A second flipping component is set up to push the pulp bag, further improving the tumbling effect of the pulp bag, so that the side of the pulp bag can better contact the iron removal roller, and at the same time improve the conveying efficiency of the pulp bag;

[0030] 3. By adjusting the distance between the first and second discs, the height of the push rod can be adjusted to enable it to push and flip pulp bags of different sizes. Attached Figure Description

Detailed Implementation

[0038] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0039] This application discloses a pulp bag conveying system.

[0040] Reference Figure 1 and Figure 2A pulp bag conveying system includes a conveying mechanism 1 for conveying pulp bags 5. A pulp dispersing trough 2 is also provided on one side of the conveying mechanism 1. The pulp bags 5 are conveyed by the conveying mechanism 1 and finally fall into the pulp dispersing trough 2 for dispersing. The conveying mechanism 1 includes a conveyor belt 11 and a mounting frame 12. The conveyor belt 11 is rotatably mounted on the mounting frame 12, and the conveyor belt 11 is inclined upwards from the side away from the pulp dispersing trough 2 towards the side closer to the pulp dispersing trough 2. The conveying mechanism 1 also includes a frame 13 and a plurality of drive rollers 14 spaced apart on the frame 13. The plurality of drive rollers 14 are parallel to each other and rotatably mounted on the frame 13. The frame 13 is located between the mounting frame 12 and the pulp dispersing trough 2. Between the troughs 2, the frame 13 is inclined downward from the side away from the slurry trough 2 to the side closer to the slurry trough 2. The frame 13 is also equipped with multiple iron removal rollers 15 for attracting iron wires. The multiple iron removal rollers 15 are parallel to each other, and the iron removal rollers 15 and the transmission rollers 14 are alternately installed on the frame 13. The frame 13 is also equipped with a flipping mechanism 3. When the slurry bag 5 is conveyed on the transmission roller 14, the flipping mechanism 3 flips the slurry bag 5 so that the other sides of the slurry bag 5 can also contact the iron removal rollers 15, so that the iron removal rollers 15 can remove the iron wires remaining on the slurry bag 5 and reduce the damage to the equipment caused by iron wires mixed in in the slurry trough 2.

[0041] Reference Figure 2 The frame 13 is also equipped with a drive assembly 16 that drives the transmission roller 14 to rotate. The drive assembly 16 includes a sprocket 161. The transmission roller 14 is horizontally arranged on the frame 13, and a transmission shaft 141 is fixed at the center of the transmission roller 14. The transmission shaft 141 is rotatably connected to the frame 13 through the transmission shaft 141, and both ends of the transmission shaft extend horizontally out of the frame 13. The sprocket 161 is coaxially fixed at the end of the transmission shaft. The number of sprockets 161 is the same as the number of transmission shafts. A chain 162 meshes between adjacent sprockets 161. A motor 163 is fixed at the end of one of the transmission shafts away from the sprocket 161. The motor 163 is fixed on the frame 13, and the output end of the motor 163 is fixedly connected to the transmission shaft. When the motor 163 drives the transmission shaft to rotate, under the transmission action of the sprocket 161 and the chain 162, multiple transmission rollers 14 rotate simultaneously in the direction closer to the slurry trough 2.

[0042] The iron removal roller 15 is a hollow cylindrical shell. A magnet post 151 is coaxially inserted inside the iron removal roller 15. The magnet post 151 can attract iron wires. The iron removal roller 15 is made of insulating material such as plastic. Multiple circular rotating ports 131 are opened through the side wall of the frame 13. The rotating ports 131 are arranged opposite to the magnet post 151. The two ends of the magnet post 151 are inserted into the rotating ports 131 and are rotatably connected to the frame 13 through the rotating ports 131. When a large number of iron wires are adsorbed on the surface of the iron removal roller 15, the magnet post 151 is pulled out horizontally, so that the surface of the iron removal roller 15 loses its magnetism, thereby causing the iron wires on the surface of the iron removal roller 15 to fall off.

[0043] Reference Figure 1 Below the iron removal roller 15 is a collection hopper 4, which is set along the length of the frame 13. The collection hopper 4 is used to collect the iron wires that fall from the iron removal roller 15, making it convenient to collect and clean the iron wires.

[0044] Reference Figure 3 and Figure 4 The flipping mechanism 3 includes a first flipping component 31, which includes a first rocker arm 311 rotatably mounted on the frame 13. A horizontally arranged rotating shaft 132 is fixed at one end of the frame 13 near the slurry trough 2. The length direction of the rotating shaft 132 is perpendicular to the length direction of the frame 13. The first rocker arm 311 is vertically fixed on the rotating shaft 132. The first rocker arm 311 is rotatably mounted on the frame 12 via the rotating shaft 132, and the first rocker arm 311 can rotate vertically with the rotating shaft 132 as the axis. An impact plate 312 is also vertically fixed in the middle section of the first rocker arm 311. The length direction of the impact plate 312 is parallel to the length direction of the transmission roller 14. When the slurry bag 5 is transported to the trough opening near the slurry trough 2 and falls downward, the slurry bag 5 will automatically impact the impact plate 312, causing the first rocker arm 311 to rotate.

[0045] A connecting rod 313 is rotatably mounted on the upper end of the first rocker arm 311. The connecting rod 313 is parallel to the length direction of the frame 13. Multiple rotating rods 314 are rotatably mounted on the connecting rod 313. In this embodiment, there are four rotating rods 314. A mounting plate 315 is also vertically fixed on one side of the frame 13. The mounting plate 315 is arranged about the length direction of the frame 13. A fixing plate 316 is vertically fixed at the end of the mounting plate 315 away from the slurry trough 2. The fixing plate 316 extends toward the slurry bag 5. The fixing plate 316 is arranged opposite to the connecting rod 313. A rocker spring 317 is fixedly connected between the connecting rod 313 and the fixing plate 316. When the connecting rod 313 moves away from the fixing plate 316, the rocker spring 317 is stretched, and the rocker spring 317 gives the connecting rod 313 a force to move toward the fixing plate 316.

[0046] Multiple rotating columns 318 are fixed at intervals in the middle section of the mounting plate 315. The number of rotating columns 318 is the same as the number of rotating rods 314, and the middle section of the rotating rods 314 is rotatably connected to the rotating columns 318. A flipping rod 319 is vertically fixed at the end of the rotating rod 314 away from the connecting rod 313. The number of flipping rods 319 is the same as the number of rotating rods 314. The flipping rods 319 extend horizontally towards the pulp bag 5. The flipping rods 319 are located above the drive roller 14, and the flipping rods 319 can approach the pulp bag 5. The lower edge of one side of the slurry tank 2 abuts against the slurry tank 2; when the first rocking rod 311 swings towards the side closer to the slurry tank 2, the rocking rod pulls the connecting rod 313 to move laterally, causing the rotating rod 314 to rotate around the rotating column 318 as the axis, thereby causing the flipping rod 319 to flip the slurry bag 5, so that the slurry bag 5 can better contact the iron removal roller 15 during the conveying process, further improving the iron wire removal effect. The rocking spring 317 realizes the reset of the rocking rod, further realizing the flipping effect of the flipping rod 319 on the next slurry bag 5.

[0047] Reference Figure 3 and Figure 5 To further improve the flipping effect of the flipping mechanism 3 on the pulp bag 5, the flipping mechanism 3 also includes a second flipping component 32. The second flipping component 32 is disposed opposite to the first flipping component 31 on the frame 13. The second flipping component 32 includes a second rocker arm 321 fixed on the rotating shaft 132. The second rocker arm 321 is parallel to the first rocker arm 311. The middle section of the second rocker arm 321 is fixedly connected to the end of the impact plate 312 away from the first rocker arm 311, and the pulp bag 5 can slide between the first rocker arm 311 and the second rocker arm 321.

[0048] A mounting rod 322 is rotatably mounted on the side wall of the second rocker arm 321 away from the impact plate 312. The rotation axis 132 of the mounting rod 322 near the second rocker arm 321 is parallel to the axis of rotation 132. A pull rod 323 is rotatably mounted on the end of the mounting rod 322 away from the second rocker arm 321. The pull rod 323 can rotate on the horizontal plane. The rotation axis 132 of the pull rod 323 is perpendicular to the axis of rotation 132 of the mounting rod 322. A plug rod 324 is rotatably mounted on the end of the pull rod 323 away from the mounting rod 322. A vertical shaft 133 is vertically fixed on the upper surface of the frame 13. The plug rod 324 is located near the end of the frame 13. A vertical hole 3241 is provided, and a vertical shaft 133 is inserted into the vertical hole 3241, so that the end of the insertion rod 324 near the frame 13 is rotatably connected to the frame 13. The end of the insertion rod 324 away from the frame 13 is bent in the direction away from the pull rod 323, and the bent part of the insertion rod 324 is rotatably connected to the end of the pull rod 323 away from the mounting rod 322. A vertical plate 134 is also vertically fixed on the frame 13. The vertical plate 134 is located on the side of the insertion rod 324 away from the pull rod 323. A return spring 325 is fixed between the vertical plate 134 and the pull rod 323. When the pull rod 323 pulls the insertion rod 324 to rotate, the return spring 325 can realize the return of the insertion rod 324.

[0049] A base plate 326 is vertically fixed on the side of the frame 13 away from the transmission roller 14. The base plate 326 extends laterally and is located on the side of the insertion rod 324 away from the pull rod 323. A first disc 327 is rotatably mounted on the base plate 326. The first disc 327 can rotate in the horizontal direction. Multiple slots 3271 are provided on the circumferential surface of the first disc 327. In this embodiment, there are four slots. The four slots 3271 are symmetrically arranged about the center of the first disc 327. The end of the insertion rod 324 away from the frame 13 can be inserted into the slot 3271. When the insertion rod 324 is inserted into the slot 3271, the first disc stops rotating.

[0050] Reference Figure 4 and Figure 5 An adjusting column 3272 is coaxially fixed on the upper surface of the first turntable. A second disc 328 is also fixed on the adjusting column 3272. A hollow adjusting cylinder 3281 is fixed at the center of the second disc 328. The axis of the adjusting cylinder 3281 and the adjusting column 3272 are on the same straight line, and the adjusting cylinder 3281 is inserted into the adjusting column 3272. The adjusting cylinder 3281 can slide vertically on the adjusting column 3272. A threaded hole 3282 is opened on the side wall of the adjusting cylinder 3281. The axis of the threaded hole 3282 is perpendicular to the axis of the adjusting column 3272. A bolt 3283 is threaded into the threaded hole 3282. The bolt 3283 passes through the threaded hole 3282 and abuts against the adjusting column 3272, so as to realize the adjustment of the position and height of the second disc 328 and meet the needs of pushing different sizes of pulp bags 5.

[0051] A push rod 329 is fixed to the circumferential wall of the second disc 328. The push rod 329 extends horizontally away from the second disc 328. The number of push rods 329 is the same as the number of slots 3271, and the push rods 329 and slots 3271 are arranged opposite each other. The push rods 329 are located on the side of the pulp bag 5 away from the drive roller 14, and the push rods 329 can push the pulp bag 5 from the top to roll on the frame 13. When the insertion rod 324 is inserted into the slot 3271, the pulp bag 5 is located on the side away from the drive roller 14. Between two adjacent push rods 329, when the second rocker arm 321 rotates toward the direction of the slurry trough 2, the pull rod 323 pulls the insertion rod 324 away from the slot 3271. At this time, the second turntable rotates, causing the push rod 329 to push the slurry bag 5 to flip. The return spring 325 resets the insertion rod 324, so that the insertion rod 324 abuts against the circumferential surface of the second disc 328 until it is inserted into the slot 3271, so that the second flipping assembly 32 continues to play the role of flipping the next slurry bag 5.

[0052] The implementation principle of a slurry bag conveying system according to an embodiment of this application is as follows:

[0053] The pulp bag 5 is conveyed to the top of the slurry tank 2 by the conveying mechanism 1. The pulp bag 5 performs slurry distribution in the slurry tank 2. During the movement of the pulp bag 5 on the conveyor belt 11, the iron wires tied to the pulp bag 5 can be preliminarily treated by the iron wire removal device. Then the pulp bag 5 falls onto the transmission roller 14 for conveying. The tumbling mechanism flips the pulp bag 5 on the transmission roller 14 so that the iron wires remaining on other surfaces of the pulp bag 5 can be attracted by the iron removal roller 15, which can separate the iron wires and reduce the adverse effects of the iron wires on subsequent slurry distribution. The first flipping component 31 pushes and flips the lower side of the pulp bag 5, and the second flipping component 32 pushes and flips the upper side of the pulp bag 5. The pushing rod 329 and the flipping rod 319 push in opposite directions to achieve the flipping of the pulp bag 5, which improves the conveying effect of the pulp bag 5 and can also fully remove the iron wires on the surface of the pulp bag 5.

[0054] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
