The papermaking machine is a complete set of equipment that makes pulp into paper webs, including the headbox, wire section, press section, drying section, calender, paper reel, and transmission section and auxiliary systems such as steam, water, vacuum, lubrication, and heat recovery.

[0003] After the paper products are formed, they generally need to go through a winding process, during which the tail paper needs to be cut. However, in the process of implementing the technical solutions in the prior art, the applicant found that the technical solutions in the prior art have the following technical problems:

[0004] When cutting the tail paper, a large amount of tail paper and empty paper rolls are generated. The inefficient movement and collection of the empty paper rolls on the production line often leads to insufficient overall production efficiency. If the paper rolls are transported too fast, the paper roll collection area will not be able to recycle them in time, resulting in paper rolls piling up and the need to suspend production. If the length of the production line is extended, the floor space will be increased. The low efficiency of paper roll recycling leads to increased production costs and reduced production efficiency.

DETAILED DESCRIPTION

[0031] The specific embodiments of the present invention are further described below in conjunction with the accompanying drawings. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0032] After the paper product is formed, it generally needs to go through a winding process. During the winding process, the tail paper needs to be cut and the cut tail paper and the empty paper roll 10 need to be returned.

[0033] When recycling the paper roll 10, if the paper roll 10 is transported too fast, the paper roll 10 collection point will often not be able to recycle in time, resulting in the accumulation of paper rolls 10 and the need to suspend production. If the length of the production line is extended, the floor space is increased. The low recycling efficiency of the paper roll 10 leads to increased production costs and reduced production efficiency.

[0034] In addition, the existing papermaking machine reel tail paper cutting and cleaning is to use a blade to cut the reel tail paper manually, and then clean the tail paper, which has high labor intensity, low cutting efficiency, time and labor, and requires a sharp blade, which can easily cause the operator to cut his fingers.

[0035] The technical solution of the embodiment of the present application provides a tail paper cutting unit, which solves the problems of low production efficiency, large labor input, insufficient production safety and high production cost in the prior art, and realizes the beneficial effects of production automation, improved production efficiency and safety, reduced labor input and production cost under the tail paper cutting unit 100, the automatic roll turning unit 200, the movable paper storage rack 310 unit 300 and the automatic guiding unit 400.

[0036] The general idea of the embodiment of the present invention to solve the above technical problems is as follows:

[0037] A tail paper cutting and roll turning machine for a paper machine, as Figure 1 shown, includes a tail paper cutting unit 100, an automatic roll turning unit 200, a movable paper storage rack 310 unit 300 and an automatic guiding unit 400; the tail paper cutting unit 100, the automatic roll turning unit 200 and the movable paper storage rack 310 unit 300 are installed on the frame 700; one end of the tail paper cutting unit is connected to the automatic roll turning unit 200; the movable paper storage rack 310 unit 300 is connected to the end of the automatic roll turning unit 200 far from the tail paper cutting unit 100; the automatic guiding unit 400 is matched with the movable paper storage rack 310 unit 300; the paper roll 10 rolls from the tail paper cutting unit to the automatic roll turning unit 200 and is driven by the automatic roll turning unit 200 to the movable paper storage rack 310 unit 300; the automatic guiding unit 400 transports the movable paper storage rack 310 unit 300 to a preset position.

[0038] After the tail paper of the paper roll is cut by the tail paper cutting unit 100, the tail paper falls down from the tail paper cutting unit to a preset collection point, and the wound paper roll 10 becomes a smooth paper roll 10. The paper roll 10 rolls through the tail paper cutting unit 100 to the automatic roll turning unit 200 and is driven by the automatic roll turning unit 200 to be collected by the movable paper storage rack 310 unit 300, thereby realizing the automation of tail paper cutting and paper roll 10 (smooth paper roll) collection, saving labor costs and improving production efficiency.

[0039] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings of the specification and specific embodiments.

[0040] A tail paper cutting and roll turning machine for a paper machine, as Figure 2 and Figure 3As shown, it includes a tail paper cutting unit, an automatic roller turning unit 200, a movable paper rack 310 unit 300 and an automatic guiding unit 400; the tail paper cutting unit 100 is connected to one end of the automatic roller turning unit 200; the movable paper rack 310 unit 300 is connected to one end of the automatic roller turning unit 200 away from the tail paper cutting unit; the automatic guiding unit 400 is matched with the movable paper rack 310 unit 300; the paper roller 10 rolls from the tail paper cutting unit 100 to the automatic roller turning unit 200 and is driven to the movable paper rack 310 unit 300 through the automatic roller turning unit 200; the automatic guiding unit 400 transports the movable paper rack 310 unit 300 to a preset position.

[0041] Specifically, the tail paper cutting unit is connected to one end of the automatic roller turning unit 200 through the inclined guide rail 500 ; the light paper roller 10 rolls along the inclined guide rail 500 from the tail paper cutting unit 100 to the front of the automatic roller turning unit 200 .

[0042] Specifically, a barrier 510 is provided at one end of the inclined guide rail 500 close to the automatic rolling unit 200; the barrier 510 is preferably a stopper.

[0043] The movable paper storage rack 310 unit 300 is provided with a bearing plate 410 , the bearing plate 410 is equipped with a movable paper storage rack 310 (movable paper storage rack), and the movable paper storage rack 310 is equipped with an empty paper roller 10 .

[0044] The movable paper storage rack 310 filled with empty paper rolls 10 is transported to a designated position by the automatic guide unit 400 to unload the empty paper rolls 10, and the empty movable paper storage rack 310 is transported back to the end of the automatic roll turning unit 200 away from the tail paper cutting unit 100 to wait for the next batch of empty paper rolls 10 to be loaded.

[0045] When in use, the automatic roller turning unit 200 turns the empty paper roll 10 into the movable paper storage rack 310. When the movable paper storage rack 310 is fully loaded, the automatic guide unit 400 drives under the movable paper storage rack 310. A guide column 420 is provided above the automatic guide unit 400. The automatic guide unit 400 raises its guide column 420, and the guide column 420 lifts the carrying plate 410. When the automatic guide unit 400 drives away, it pushes the carrying plate 410 and the movable paper storage rack 310 located on the carrying plate 410 to transport the movable paper storage rack 310 containing the empty paper roll 10 to the designated unloading point through a preset path, and then unloads the empty paper roll 10, and transports the empty movable paper storage rack 310 back to the end of the automatic roller turning unit 200 away from the tail paper cutting unit 100 to wait for the next batch of empty paper rolls 10 to be loaded.

[0046] The automatic guided vehicle unit 400 is preferably an AGV mobile vehicle; the AGV mobile vehicle is matched with the movable paper storage rack 310 unit 300.

[0047] The AGV mobile cart transports the movable paper roll storage rack 310 filled with empty paper rolls 10 to the designated position to unload the empty paper rolls 10, and transports the empty movable paper roll storage rack 310 back to one end of the automatic roll turning unit 200 far away from the tail paper cutting unit 100.

[0048] To avoid unnecessary mutual impacts caused by the disorderly entry of the paper rolls 10 into the automatic roll turning unit 200, the tail paper cutting unit 100 is provided with a paper roll dropping roller stop mechanism 110 and a paper roll positioning mechanism 120; the paper roll positioning mechanism 120 is composed of a positioning hook plate 121 and a hook plate cylinder 123 for driving the positioning hook plate 121.

[0049] The automatic roll turning unit 200 is composed of a roll turning hook plate 210, a roll turning hinge shaft 211 passing through the roll turning hook plate 210, and a roll turning cylinder 220 for driving the roll turning hook plate 210.

[0050] The hook plate cylinder 123 is started to push one end of the positioning hook plate 121 upward and the other end downward, and the paper roll 10 slides along the inclined guide rail 500 onto the roll turning hook plate 210 of the automatic roll turning unit 200, and the paper roll 10 is blocked by a blocking object 510, preferably a block. The roll turning cylinder 220 is started to drive the roll turning hook plate 210 to rotate and drive the paper roll 10 to turn into the movable paper roll storage rack 310.

[0051] The top of the roll turning hook plate 210 is provided with a convex part to prevent the paper roll 10 from sliding backward during the turning process and ensure the smoothness of the roll turning process.

[0052] The shape of the roll turning hook plate 210 is in the shape of a "7", and there is an arc above the roll turning hook plate 210. When the roll turning hook plate 210 is turned up, if another paper roll 10 slides under the roll turning hook plate 210, the side of the roll turning hook plate 210 far away from the movable paper roll storage rack 310 blocks the other paper roll to prevent the other paper roll 10 from sliding to the movable paper roll storage rack and causing a collision. When the roll turning hook plate 210 is turned to the highest point and the previous paper roll 10 is sent to the movable paper roll storage rack, the roll turning hook plate 210 returns to its original position, and the upper part of the roll turning hook plate 210 completely drops to a position lower than the inclined guide rail 500, and the paper roll 10 slides to the side of the roll turning hook plate 210 close to the movable paper roll storage rack under the action of gravity. The roll turning cylinder 220 is started again to drive the roll turning hook plate 210 to rotate and drive the paper roll 10 to turn into the movable paper roll storage rack 310, and so on in a cycle.

[0053] A collection tray 600 is provided below the tail paper cutting unit 100 to collect the cut tail paper waste.

[0054] To reduce the safety hazard of manually cutting the tail paper of the paper roll shaft and improve the efficiency, the embodiment of the present invention uses a water needle cutting mechanism 1000 instead of manual labor. The water needle cutting mechanism 1000 includes:

[0055] As Figure 6As shown, the lifting drive device 1100 is movably installed on the papermaking equipment and can reciprocate along the first preset direction; a friction block 1110 is provided below the lifting drive device 1100 to fix the paper roll 10.

[0056] The cutting device 1300 is movably connected to the lifting drive device 1100, and the cutting device 1300 is driven by the lifting drive device 1100 to reciprocate along the second preset direction; the cutting device 1300 is composed of a plurality of cutting components;

[0057] Wherein, each cutting component includes a first high-pressure water needle 1410, a first air spray pipe 1510 located at one end of the first high-pressure water needle 1410, a second high-pressure water needle 1420 located at the end of the first air spray pipe 1510 away from the first high-pressure water needle 1410, and a second air spray pipe 1520 located at the end of the second high-pressure water needle 1420 away from the first air spray pipe 1510; a first separating member 1600 is provided below the second high-pressure water needle 1420.

[0058] Specifically, the bottom heights of the first high-pressure water needle 1410, the first air spray pipe 1510, the second high-pressure water needle 1420, and the second air spray pipe 1520 decrease in sequence.

[0059] Wherein, the first high-pressure water needle 1410 and the second high-pressure water needle 1420 spray high-pressure water jets; the first air spray pipe 1510 and the second air spray pipe 1520 spray compressed air.

[0060] Specifically, the number of the cutting devices 1300 is 1.

[0061] Specifically, a second separating member 1700 is provided between each cutting component and each cutting component is symmetrically designed.

[0062] More specifically, the number of the cutting components is 2, which are the first cutting component 1310 and the second cutting component 1320 that are symmetric to each other, and the use of multiple cutting components improves the cutting speed and efficiency.

[0063] More specifically, the first preset direction and the second preset direction are perpendicular to each other; the first preset direction is perpendicular to the ground, and the second preset direction is parallel to the ground.

[0064] When using the water needle cutting mechanism 1000, to improve the cutting efficiency, the high-pressure water needles are arranged in the following way that two water needles are used for cutting successively in the front and back during each one-way use:

[0065] A. When the cutting device 1300 drives the high-pressure water needles to cut to the left, the first high-pressure water needle 1410 and the second high-pressure water needle 1420 cut simultaneously;

[0066] B. The height of the second high-pressure water needle 1420 is lower than the bottom height of the first high-pressure water needle 1410. Specifically, the height of the second high-pressure water needle 1420 is about 30 mm lower than the bottom height of the first high-pressure water needle 1410. The cutting depth of the first high-pressure water needle 1410 is 30-40 mm, and the cutting depth of the second high-pressure water needle 1420 is about 20-30 mm.

[0067] C. The total cutting depth of each single pass is about 60mm or more, which improves the cutting efficiency accordingly.

[0068] Specifically, the first separation member 1600 and the second separation member 1700 are a wedge-shaped block and a three-dimensional triangular paper separator respectively;

[0069] Among them, the function of the first separation piece 1600 (wedge block) is to clear the channel for the second high-pressure water needle 1420 and the second jet pipe 1520 to prevent the second high-pressure water needle 1420 and the second jet pipe 1520 from being stuck by paper during movement, thereby effectively improving the cutting (production) efficiency.

[0070] In addition, the second separation member 1700 (tail paper separation inclined block) moves along the cutting opening to open the cutting opening, so that the cut tail paper can fall off and be cleaned, thereby further achieving the technical effect of reducing labor intensity and the probability of work-related injuries and improving production efficiency.

[0071] Different materials of paper require different cutting depths. In order to improve the flexibility of the water needle cutting mechanism 1000:

[0072] The second separation piece 1700 is designed to be independently adjustable in height.

[0073] The process of cutting the tail paper requires effective limit positioning of the cutting device 1300:

[0074] By connecting the lifting drive device 1100 and the guide rod 1200 of the cutting device 1300, the height of the cutting device 1300 can be adjusted according to production needs.

[0075] Specifically, it also includes a water needle sleeve 1430 sleeved outside the first high-pressure water needle 1410 and the second high-pressure water needle 1420 and an air nozzle 1511 arranged below the first air jet pipe 1510 and the second air jet pipe 1520; the lifting drive device 1100 is an electric cylinder combination.

[0076] Reference Figure 1 , the method of using the embodiment of the present invention is as follows:

[0077] 1.1. The tail paper roll 10 to be cut is hoisted in by a crane and falls onto the inclined guide rail 500 of the automatic tail paper cutting unit 100 along the left and right and rear stop gauges (at this time: a. The positioning hook plate 121 of the paper roll 10 rises to the highest position, and the hook plate cylinder 123 returns to the zero position, i.e. the lowest position, and the paper roll 10 is positioned horizontally;

[0078] b. The vertical positioning mechanism cylinder returns to zero position (i.e. the highest position)

[0079] 1.2. The tail paper roller 10 falls into the inclined guide rail 500 and rolls along the inclined guide rail 500 to the positioning hook plate 121 (a rolling bearing is installed in the sleeve of the tail paper roller 10);

[0080] After the horizontal positioning is stable, the cylinder of the vertical positioning mechanism moves downward, driving the arc-shaped friction block below the cylinder to press down to the surface of the tail paper roller 10, so that the tail paper roller 10 is reliably fixed at the water needle cutting position, completing the cutting positioning;

[0081] 1.3. After the tail paper cutting is completed, the hook plate cylinder 123 rises, and the positioning hook plate 121 drops to the lowest position. At this time, the highest point of the hook plate is lower than the upper surface of the inclined guide rail 500; the remaining light paper roller 10 after the tail paper cutting rolls along the inclined guide rail 500 to the rear stopper of the guide rail 500 and stops;

[0082] 1.4. At this point, the first working action of the tail paper cutting unit 100 is completed, and steps 1 to 3 are repeated in sequence.

[0083] 2.1. Continuing from the above, when the light paper roll 10 after the tail paper is cut is released when the positioning hook plate 121 of the cutting unit is lowered, the roller hook plate 210 of this unit is at zero position (ie, the lowest point);

[0084] The rolling hook plate 210 can perform the rolling action only when it is detected that there is a light paper roller 10 at the rear stopper of the guide rail 500 .

[0085] 2.2. When the paper tube roller 10 is detected at the rear stopper of the guide rail 500, the roller cylinder 220 extends from the zero position, driving the roller hook plate 210 to rotate around the roller hinge shaft 211 and flip backward;

[0086] a. When the roller is turned over after starting, the light paper roller 10 rolls along the contour curve on the back of the roller hook, and the front inclined surface of the rear block of the guide rail 500 turns over.

[0087] b. When the light paper roller 10 is flipped back to the highest point of the inclined surface before the rear block of the guide rail 500, the roller hook plate 210 continues to flip back, and the light paper roller 10 is driven by the roller hook plate 210 to roll backward along the inclined surface of the rear block of the guide rail 500;

[0088] c. When the roller hook plate 210 is flipped to the highest position, the light paper roller 10 continues to roll backward along the downward inclined surface of the upper portion of the rear block of the guide rail 500 under the initial force of the roller hook plate 210 until it rolls to the movable paper storage rack 310 unit 300;

[0089] d. The light paper roller 10 continues to roll backward along the inclined surface of the movable paper rack 310 of the unit 300 on the guide rail 500 under the action of gravity, and eventually rolls to the movable paper rack and stops from the rear end;

[0090] At this point, a rolling action is completed.

[0091] 2.3. After the first roller release action is completed, the piston rod of the rolling cylinder retracts to the zero position, driving the roller hook plate 210 to rotate to the lowest position;

[0092] At this time, due to the front curve of the roller hook plate 210, it is always against the subsequent light paper roller 10, and when the fixed hook plate rolls back and forth, there is no phenomenon of the roller hook plate 210 getting stuck, and continuous rolling can be achieved;

[0093] 2.4. Repeat steps 1 to 3 in sequence.

[0094] 3.1. When the paper rack unit is fully loaded with 10 rolls of glossy paper for the first time, the AGV mobile car enters the bottom of the paper rack and waits for the next roll.

[0095] 3.2. When the paper storage rack unit is full of light paper rolls 10, the AGV mobile trolley carrier plate 410 rises, holds the movable paper storage rack, moves it out of the paper storage rack unit, and transports it as a whole to the storage place of the light paper rolls 10;

[0096] 3.3. After the unloading of the light paper roll 10 to the storage place is completed, the AGV mobile car carries the empty movable paper storage rack back to the automatic tail paper cutting and rolling machine, waiting for the next operation of the paper roll 10;

[0097] 3.4. Repeat all the above steps in sequence to achieve full automation.

[0098] The paper roll tail paper cutting roller machine can be used for cutting the tail paper of facial tissue, such as Figures 7 - 10 As shown, the details are as follows:

[0099] 1. The tail paper roll to be cut is hoisted in by a crane and falls along the left, right and rear side stops onto the inclined guide rails of the automatic tail paper cutting unit.

[0100] (At this time: a. The paper roller positioning hook plate rises to the highest position, and the hook plate cylinder returns to the zero position, that is, the lowest position, and the paper roller is positioned horizontally;

[0101] b. The vertical positioning mechanism cylinder returns to zero position (i.e. the highest position)

[0102] 2. The waste paper roll that falls into the inclined guide rail rolls along the inclined guide rail surface to the positioning hook plate (a rolling bearing is installed inside the waste paper roll shaft sleeve);

[0103] After the horizontal positioning is stable, the cylinder of the vertical positioning mechanism acts to press down, driving the arc-shaped friction block below the cylinder to press down on the waste paper roll surface,

[0104] so that the waste paper roll is reliably fixed at the water jet cutting position to complete the cutting positioning;

[0105] 3. After the waste paper cutting is completed, the hook plate cylinder rises, and at the same time, the positioning hook plate descends to the lowest position. At this time, the highest point of the hook plate is lower than the upper surface of the inclined guide rail;

[0106] The remaining smooth paper roll after the waste paper cutting rolls along the inclined guide rail to stop at the rear stop block of the guide rail;

[0107] 4. At this point, the first working action of the waste paper cutting unit is completed. Repeat steps 1 to 3 and cycle in turn.

[0108] Specifically, the steps are as follows:

[0109] 1. After being cut by the cutting part, the smooth roll rolls from the inclined guide rail of the cutting part to the rear stop block, and then is turned to the paper storage roll part by the turning mechanism;

[0110] 2. When the smooth paper roll after the waste paper is cut is released when the positioning hook plate of the cutting unit descends, the turning hook plate of this unit is at the zero position (i.e., the lowest position); only when it is detected that there is a smooth paper roll at the rear stop block of the guide rail can the turning hook plate perform the turning action;

[0111] 3. After a smooth paper roll is detected at the rear stop block of the guide rail, the turning cylinder extends from the zero position, driving the turning swing arm to rotate and turn backward around the turning hinge shaft;

[0112] a. When starting to turn backward, the smooth paper roll rolls along the profiling curve on the upper back surface of the turning swing arm and the inclined front surface in front of the rear stop block of the guide rail and then

[0113] turns

[0114] b. When the smooth paper roll turns backward to the highest point of the inclined front surface in front of the rear stop of the guide rail, the turning swing arm continues to turn backward. At this time, the smooth paper roll rolls backward along the inclined upper surface of the rear stop block of the guide rail under the drive of the turning hook plate;

[0115] c. When the smooth roll rolls to the first 1 / 3 stroke in front of the rear stop of the guide rail, the smooth roll is transferred from the rear edge curve of the turning swing arm to the connecting rod side plate of the four-bar mechanism and continues to roll. The smooth paper roll rolls along the inclined surface of the connecting rod side plate to the rearmost end of the connecting rod side plate;

[0116]

[0117] ​d. When the detection light roller rolls to the rearmost end of the connecting rod side plate and reaches the position, the air cylinder retracts, the piston rod of the air cylinder retracts to the zero position, driving the connecting rod side plate of the four-link mechanism to descend, and finally smoothly landing on the guide rail surface of the paper storage rack part, thus completing a roller turning action;

[0118] 4. At this time, due to the curve at the front end of the roller turning swing arm, it has been continuously pressing against the subsequent incoming light paper rollers. Therefore, when the roller turning swing arm reciprocates to turn the roller, there is no phenomenon of the roller turning hook plate getting stuck, and continuous roller turning can be achieved;

[0119] 5. Repeat steps 2 to 4 in sequence and cycle.

[0120] More specifically, the process of water needle cutting is as follows:

[0121] 1. Water needle cutting mechanism: When receiving the signal that the tail paper roller positioning is completed, the water needle descends from the initial position under the drive of the servo electric cylinder to cut the tail paper, and at the same time, it is driven by the transverse movement mechanism to move back and forth (filtered high-pressure water is supplied inside the water needle / compressed air is passed through the air pipe. The cut tail paper is first blown open by the blowing pipe and then separated by the paper separating head and the separator;

[0122] After the cutting is completed, the water needle returns to the initial position under the drive of the transverse movement mechanism, completing one cycle;

[0123] 2. Transverse movement mechanism: Driven by the servo motor and controlled by the program, the water needle cutting mechanism is driven to move back and forth by the sprocket and chain mechanism.

[0124] Specifically, as Figure 11 shown, the working process of the movable paper storage rack is as follows:

[0125] 1. When the first roller turning is carried out until the paper storage rack unit is full of light paper rollers, the AGV mobile cart enters and waits at the bottom of the paper storage rack

[0126] 2. When the paper storage rack unit is full of light paper rollers, the bearing plate of the AGV mobile cart rises, supports the movable paper storage rack, and moves out from the paper storage rack unit, and is transported as a whole to the light paper roller storage place;

[0127] 3. After the light paper rollers are unloaded at the storage place, the AGV mobile cart carries the empty movable paper storage rack back to the automatic tail paper cutting and roller turning machine and waits for the next operation of the tube paper rollers;

[0128] 4. Repeat all the above steps in sequence and cycle, so as to achieve full automation.

[0129] The above has described the embodiments of the present invention in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, without departing from the principle and spirit of the present invention, various changes, modifications, substitutions and variations made to these embodiments still fall within the protection scope of the present invention.
