Description

Technical Field

[0001] The present invention relates to the technical field of paper tube palletizing, and particularly relates to a paper tube slitting and palletizing device. Background Art

[0002] A paper tube is a shaped material with a certain pressure-bearing capacity composed of multiple layers of paper sheets through bonding or pressing, and is usually used as a transportation package or a winding carrier; the initially produced paper tube is in the shape of a long tube and cannot be directly used. It needs to be cut into a specified length for easy use. At the same time, the cut paper tubes need to be palletized for subsequent use and storage. An aisle stacker is an automated warehousing device mainly used in high-density storage warehouses, responsible for operations such as stacking, picking, and transporting goods in narrow aisles. The cut paper tubes need to be uniformly palletized by the aisle stacker. In the prior art, the loading, unloading, and positioning of paper tube slitting and palletizing equipment all require manual operation, which cannot ensure the accuracy of the cutting length, and at the same time, the automatic palletizing of paper tubes cannot be achieved, which is not convenient for the subsequent use of paper tubes. Summary of the Invention

[0003] In view of the above technical problems, the technical solution adopted by the present invention is: a paper tube slitting and palletizing device, including a palletizing mechanism for palletizing paper tubes. The palletizing mechanism includes a palletizing box. A conveying mechanism for conveying paper tubes and a slitting mechanism for slitting paper tubes are arranged on the palletizing mechanism. The conveying mechanism includes a conveying bracket, a fixed frame is fixedly installed on the conveying bracket, and a rotating column is rotatably installed on the fixed frame. The slitting mechanism includes a pressing frame. The palletizing mechanism includes a lifting plate rotatably installed on the palletizing box, an opening and closing plate is rotatably installed on the lifting plate, a lifting plate is slidably installed on the palletizing box, a plurality of blocking blocks are fixedly installed on the lifting plate, a conveyor belt driven by a motor is arranged below the palletizing box, a pallet is fixedly installed on the conveyor belt, a placement box is placed on the pallet, and a semi-toothed gear is rotatably installed on the conveying bracket.

[0004] Furthermore, the palletizing mechanism further includes a palletizing gear fixedly installed on the lifting plate. The palletizing gear meshes with the semi-toothed gear. The blocking block is slidably installed with the palletizing box. A blocking spring is arranged between the lifting plate and the palletizing box. A slope is arranged inside the palletizing box. A torsion spring is arranged between the opening and closing plate and the lifting plate. A torsion spring is arranged between the lifting plate and the palletizing box.

[0005] The finally slit paper tubes ultimately enter the stacking box and slide along the slope inside the stacking box to above the lifting plate. When the lifting plate is in a horizontal state, the blocking spring is in a compressed state. When the half-toothed gear meshes with the stacking gear, it drives the stacking gear and the lifting plate to rotate. When the lifting plate rotates, it will lift the paper tubes located on it together. The torsion spring between the lifting plate and the stacking box is twisted. The elastic force of this torsion spring is greater than that of the blocking spring, causing the paper tubes to gradually reach an upright state. Finally, the paper tubes fall onto the opening and closing plate. When the paper tubes are upright, their gravity presses the opening and closing plate to rotate, and the torsion spring between the opening and closing plate and the lifting plate is twisted. Subsequently, the paper tubes fall upright into the placement box below. When the paper tubes fall out, the torsion spring between the opening and closing plate and the lifting plate rebounds and resets. When the lifting plate rotates upwards, the blocking spring resets, causing the lifting plate and the blocking block to rise. The blocking block blocks the subsequent paper tubes. When the stacking gear disengages from the half-toothed gear, the torsion spring between the lifting plate and the stacking box rebounds, causing the lifting plate to reset and press down the lifting plate again. The blocking spring is compressed, and the blocking block retracts. The subsequent paper tubes in the stacking box roll onto the lifting plate, and so on.

[0006] There are several stacking spaces arranged in the placement box. The paper tubes slide along the lifting plate and fall into the stacking spaces of the placement box. Subsequently, the conveyor belt drives the pallet and the placement box to move, moving the placement box along the aisle of the three-dimensional warehouse to the designated three-dimensional warehouse location. Subsequently, through equipment such as a robotic arm, the placement box is stacked into the three-dimensional warehouse. The empty placement box can be placed on the pallet, and the conveyor belt drives the placement box to move to the lifting plate again for paper tube stacking.

[0007] Further, the conveying mechanism includes a placing box fixedly installed on the conveying bracket. A motor is arranged below the conveying bracket. A transmission column is fixedly installed on the motor shaft of the motor. Several slow wheels and fast wheels are rotatably installed on the conveying bracket. The transmission column drives all the slow wheels and all the fast wheels to rotate respectively through belt drives. The transmission ratio of the belt driving the slow wheels is greater than that of the belt driving the fast wheels. The rotation speed of the fast wheels is greater than that of the slow wheels.

[0008] Further, a small cam and a large cam are rotatably installed on the conveying bracket. A pressing column is slidably installed on the conveying bracket. A blocking plate is fixedly installed on the pressing column. A spring is arranged between the pressing column and the conveying bracket. The large cam contacts the pressing column, and the small cam contacts the pressing frame. The transmission column drives the small cam and the large cam to rotate through belt drives.

[0009] Further, the fast wheels drive the rotating column to rotate through gear transmission and belt transmission. The transmission column drives the half-toothed gear to rotate through belt transmission.

[0010] The small cam has a half-turn of small-radius area, a quarter-turn of large-radius area, and a quarter-turn of transition area for the transition from small radius to large radius. The large cam has a half-turn of large-radius area, a quarter-turn of small-radius area, and a quarter-turn of transition area for the transition from small radius to large radius.

[0011] The motor drives the drive column to rotate, and through belt drive, it drives all the slow wheels and fast wheels to rotate. The transmission ratio of the belt driving the slow wheels is greater than that of the belt driving the fast wheels, and the rotation speed of the fast wheels is greater than that of the slow wheels. At the same time, the drive column drives the small cam and the large cam to rotate synchronously through belt drive. The drive column drives the half-tooth gear to rotate through belt drive. The fast wheels drive the rotating column to rotate through gear drive and belt drive. When in use, the paper tube to be cut is placed into the box, and then the paper tube enters the conveying bracket. The slow wheels convey the paper tube to the baffle. When the large cam rotates to the large-radius area and contacts the pressing column, it will press down the pressing column and the baffle. The baffle blocks the paper tube, and the spring between the pressing column and the conveying bracket is compressed. At this time, the small cam has not yet pressed down the pressing frame. The transition area of the small cam contacts the pressing frame and begins to gradually press down the pressing frame. When the large cam and the small cam continue to rotate a quarter-turn, the baffle remains pressed down. The large-radius area of the small cam contacts the pressing frame, and the small cam completes pressing down the pressing frame. The spring between the pressing frame and the conveying bracket is compressed, and the rotating saw blade cuts the paper tube. Subsequently, the small-radius area of the small cam begins to contact the pressing frame, and the small-radius area of the large cam begins to contact the pressing column. The baffle and the pressing frame rise simultaneously under the action of the spring reset. The fast wheels quickly convey the cut paper tube to the stacking box, and the slow wheels continue to convey the paper tube to be cut towards the baffle.

[0012] After the large cam presses down the pressing column and the baffle, it continues to rotate a quarter-turn before the small cam begins to press down the pressing frame. And the rotation speed of the fast wheels is greater than that of the slow wheels, resulting in a speed difference between the conveying speeds of the cut paper tube and the uncut paper tube. Also, the baffle descends prior to the pressing frame, ensuring that the baffle can block the paper tube to be cut, and the cut paper tube is conveyed behind the baffle.

[0013] Furthermore, the slitting mechanism includes an adjusting screw rod rotatably installed on the fixed frame. A handle is rotatably installed on the fixed frame, and the handle drives the adjusting screw rod to rotate through gear drive. A spring is provided between the pressing frame and the conveying bracket. A movable frame is slidably installed on the fixed frame, and the movable frame forms a screw drive with the adjusting screw rod.

[0014] Further, a sliding gear is rotatably installed on the movable frame. The sliding gear is slidably installed on the rotating column. A pressing frame is fixedly installed below the pressing frame. A cutting plate is slidably installed on the pressing frame. A spring is arranged between the cutting plate and the pressing frame. The pressing frame is slidably installed on the movable frame. A spring is arranged between the pressing frame and the movable frame. A tool rest is fixedly installed on the cutting plate. A rotating saw blade driven by a motor is arranged on the tool rest.

[0015] Further, an inner lower gear is rotatably installed on the movable frame. An outer lower gear is fixedly installed on the inner lower gear. An outer rotating plate is rotatably installed on the outer lower gear. The sliding gear meshes with the inner lower gear. An upper gear is rotatably installed on the outer rotating plate. An outer transmission belt is wound around the outer lower gear and the upper gear. An inner rotating rod is rotatably installed on the outer rotating plate. The upper gear is rotatably installed on the inner rotating rod. A lower gear is rotatably installed on the inner rotating rod. An inner transmission belt is wound around the upper gear and the lower gear. A friction wheel is fixedly installed on the lower gear. The friction wheel is rotatably installed on the cutting plate.

[0016] By rotating the handle, the handle can be driven to rotate through gear transmission, thereby driving the movable frame to slide along the fixed frame, so as to adjust the position of the movable frame and the cutting length of the paper tube. The movable frame slides along the rotating column, and the sliding gear always meshes with the inner lower gear.

[0017] When the pressing frame descends, it drives the pressing frame to descend. The spring between the pressing frame and the movable frame is compressed. The spring between the pressing frame and the cutting plate drives the cutting plate, the tool rest, the rotating saw blade and the friction wheel to descend. The descent of the friction wheel causes the inner rotating rod to rotate relative to the outer rotating plate, and the outer rotating plate rotates relative to the outer lower gear. The rotating column drives the sliding gear to rotate, driving the inner lower gear and the outer lower gear to rotate. The upper gear is driven to rotate through the outer transmission belt. The lower gear and the friction wheel are driven to rotate through the inner transmission belt. When the friction wheel contacts the paper tube, if the pressing frame continues to descend, the spring between the pressing frame and the cutting plate will be stretched, which can adapt to paper tubes of different diameters, and at the same time makes the friction wheel press tightly on the surface of the paper tube. At this time, the rotating saw blade rotates to cut the paper tube, and at the same time the friction wheel rotates to drive the paper tube to rotate automatically, realizing the efficient slitting of the paper tube.

[0018] The beneficial effects of the present invention compared with the prior art are as follows: (1) The stacking mechanism provided by the present invention can automatically stack the slit paper tubes vertically in multiple placement spaces of the placement box, and drive the placement box to move in the aisle of the stereoscopic warehouse through the conveyor belt for stacking, and the stacking effect is good; (2) The conveying mechanism and the slitting mechanism provided by the present invention can cooperate to achieve the efficient and accurate cutting of the paper tube. At the same time, the whole process of paper tube conveying, cutting and stacking is fully automatic, with high automation degree and good continuity; (3) The slitting mechanism provided by the present invention can drive the paper tube to rotate automatically when cutting the paper tube, with good slitting effect, can slit paper tubes of different diameters, and can adjust the required slitting length, with good adaptability.

Detailed Description of the Invention

[0029] The following further describes the specific embodiments of the present invention in conjunction with the accompanying drawings.

[0030] Embodiment: Refer to Figures 1-9 , a paper tube slitting and palletizing device, including a palletizing mechanism for palletizing paper tubes. The palletizing mechanism includes a palletizing box 101. A conveying mechanism for conveying paper tubes and a slitting mechanism for slitting paper tubes are provided on the palletizing mechanism. The conveying mechanism includes a conveying bracket 201. A fixed frame 203 is fixedly installed on the conveying bracket 201. A rotating column 211 is rotatably installed on the fixed frame 203. The slitting mechanism includes a pressing frame 301; The palletizing mechanism includes a lifting plate 102 rotatably installed on the palletizing box 101. An opening and closing plate 103 is rotatably installed on the lifting plate 102. A lifting plate 104 is slidably installed on the palletizing box 101. A number of blocking blocks 105 are fixedly installed on the lifting plate 104. A conveyor belt 111 driven by a motor is provided below the palletizing box 101. A pallet 110 is fixedly installed on the conveyor belt 111. A placement box 109 is placed on the pallet 110. A semi-toothed gear 108 is rotatably installed on the conveying bracket 201.

[0031] As Figure 2 、 Figure 3 shown, the palletizing mechanism further includes a palletizing gear 107 fixedly installed on the lifting plate 102. The palletizing gear 107 meshes with the semi-toothed gear 108. The blocking block 105 is slidably installed with the palletizing box 101. A blocking spring 106 is provided between the lifting plate 104 and the palletizing box 101. A slope is provided inside the palletizing box 101. A torsion spring is provided between the opening and closing plate 103 and the lifting plate 102. A torsion spring is provided between the lifting plate 102 and the palletizing box 101.

[0032] The slit paper tubes finally enter the palletizing box 101 and slide along the slope inside the palletizing box 101 to above the lifting plate 102. When the lifting plate 102 is in a horizontal state, the blocking spring 106 is in a compressed state. When the semi-toothed gear 108 meshes with the palletizing gear 107, it drives the palletizing gear 107 and the lifting plate 102 to rotate. When the lifting plate 102 rotates, it will lift the paper tubes located on it together. The torsion spring between the lifting plate 102 and the palletizing box 101 is twisted. The elastic force of this torsion spring is greater than the elastic force of the blocking spring 106, causing the paper tubes to gradually reach an upright state. Finally, the paper tubes fall onto the opening and closing plate 103. When the paper tubes are upright, their gravity presses the opening and closing plate 103 to rotate. The torsion spring between the opening and closing plate 103 and the lifting plate 102 is twisted. Subsequently, the paper tubes fall upright into the lower placement box 109. When the paper tubes fall out, the torsion spring between the opening and closing plate 103 and the lifting plate 102 rebounds and resets. When the lifting plate 102 rotates up, the blocking spring 106 resets, causing the lifting plate 104 and the blocking block 105 to rise. The blocking block 105 blocks the subsequent paper tubes. When the palletizing gear 107 disengages from the semi-toothed gear 108, the torsion spring between the lifting plate 102 and the palletizing box 101 rebounds, causing the lifting plate 102 to reset and press the lifting plate 104 down again. The blocking spring 106 is compressed, and the blocking block 105 retracts. The subsequent paper tubes in the palletizing box 101 roll onto the lifting plate 102, and so on.

[0033] There are several stacking spaces provided in the placement box 109. The paper tubes slide along the lifting plate 102 into the stacking spaces of the placement box 109. Subsequently, the conveyor belt 111 drives the pallet 110 and the placement box 109 to move, moving the placement box 109 along the aisle of the stereoscopic warehouse to the designated stereoscopic warehouse location. Subsequently, through equipment such as a robotic arm, the placement box 109 is stacked in the stereoscopic warehouse. The empty placement box 109 can be placed on the pallet 110, and the conveyor belt 111 drives the placement box 109 to move to the lifting plate 102 again for paper tube palletizing.

[0034] As Figures 4-6 shown, the conveying mechanism includes a loading box 212 fixedly installed on the conveying bracket 201. A motor 208 is provided below the conveying bracket 201. A transmission column 202 is fixedly installed on the motor shaft of the motor 208. A number of slow wheels 209 and fast wheels 210 are rotatably installed on the conveying bracket 201. The transmission column 202 drives all the slow wheels 209 and all the fast wheels 210 to rotate through belt drives respectively. The transmission ratio of the belt driving the slow wheels 209 is greater than the transmission ratio of the belt driving the fast wheels 210. The rotation speed of the fast wheels 210 is greater than the rotation speed of the slow wheels 209.

[0035] As Figures 4-6As shown in the figure, a small cam 204 and a large cam 205 are rotatably mounted on the conveying bracket 201. A pressing column 207 is slidably mounted on the conveying bracket 201. A blocking plate 206 is fixedly mounted on the pressing column 207. A spring is provided between the pressing column 207 and the conveying bracket 201. The large cam 205 contacts the pressing column 207, and the small cam 204 contacts the pressing frame 301. The transmission column 202 drives the small cam 204 and the large cam 205 to rotate through belt drive.

[0036] As Figures 4-6 shown, the fast wheel 210 drives the rotating column 211 to rotate through gear drive and belt drive. The transmission column 202 drives the half-tooth gear 108 to rotate through belt drive.

[0037] Half of the small cam 204 is a small radius area, one-fourth of it is a large radius area, and one-fourth of it is a conversion area for the conversion from a small radius to a large radius. Half of the large cam 205 is a large radius area, one-fourth of it is a small radius area, and one-fourth of it is a conversion area for the conversion from a small radius to a large radius.

[0038] The motor 208 drives the transmission column 202 to rotate, and drives all the slow wheels 209 and fast wheels 210 to rotate through belt transmission. The transmission ratio of the transmission belt driving the slow wheel 209 is greater than that of the transmission belt driving the fast wheel 210. The rotation speed of the fast wheel 210 is greater than that of the slow wheel 209. At the same time, the transmission column 202 drives the small cam 204 and the large cam 205 to rotate simultaneously and synchronously through belt transmission. The transmission column 202 drives the half-tooth gear 108 to rotate through belt transmission. The fast wheel 210 drives the rotating column 211 to rotate through gear transmission and belt transmission. When in use, the paper tube to be cut is placed into the placing box 212, and then the paper tube enters the conveying bracket 201. The slow wheel 209 conveys the paper tube to the blocking plate 206. When the large cam 205 rotates to the large-radius area and contacts the pressing column 207, it will press down the pressing column 207 and the blocking plate 206. The blocking plate 206 blocks the paper tube, and the spring between the pressing column 207 and the conveying bracket 201 is compressed. At this time, the small cam 204 has not yet pressed down the pressing frame 301. The conversion area of the small cam 204 contacts the pressing frame 301 and begins to gradually press down the pressing frame 301. When the large cam 205 and the small cam 204 continue to rotate a quarter of a circle, the blocking plate 206 remains pressed down. The large-radius area of the small cam 204 contacts the pressing frame 301, and the small cam 204 completes pressing down the pressing frame 301. The spring between the pressing frame 301 and the conveying bracket 201 is compressed, and the rotating saw blade 317 cuts the paper tube. Subsequently, the small-radius area of the small cam 204 begins to contact the pressing frame 301, and the small-radius area of the large cam 205 begins to contact the pressing column 207. The blocking plate 206 and the pressing frame 301 rise simultaneously under the action of spring reset. The fast wheel 210 quickly conveys the cut paper tube to the stacking box 101, and the slow wheel 209 continues to convey the paper tube to be cut towards the blocking plate 206.

[0039] After the large cam 205 presses down the pressing column 207 and the blocking plate 206 and continues to rotate a quarter of a circle, the small cam 204 begins to press down the pressing frame 301. And the rotation speed of the fast wheel 210 is greater than that of the slow wheel 209, resulting in a speed difference between the conveying speeds of the cut paper tube and the uncut paper tube. And the blocking plate 206 descends prior to the pressing frame 301, ensuring that the blocking plate 206 can block the paper tube to be cut, and the cut paper tube is conveyed behind the blocking plate 206.

[0040] As Figures 7-9 shown, the slitting mechanism includes an adjusting screw rod 302 rotatably installed on the fixed frame 203. A handle 303 is rotatably installed on the fixed frame 203. The handle 303 drives the adjusting screw rod 302 to rotate through gear transmission. A spring is arranged between the pressing frame 301 and the conveying bracket 201. A movable frame 306 is slidably installed on the fixed frame 203, and the movable frame 306 forms a threaded transmission with the adjusting screw rod 302.

[0041] As shown Figures 7-9 in the figure, a sliding gear 307 is rotatably installed on the movable frame 306. The sliding gear 307 is slidably installed on the rotating column 211. A pressing frame 304 is fixedly installed below the pressing frame 301. A cutting plate 305 is slidably installed on the pressing frame 304. A spring is provided between the cutting plate 305 and the pressing frame 304. The pressing frame 304 is slidably installed on the movable frame 306. A spring is provided between the pressing frame 304 and the movable frame 306. A tool rest 318 is fixedly installed on the cutting plate 305. A rotating saw blade 317 driven by a motor is provided on the tool rest 318.

[0042] As shown Figures 7-9 in the figure, an inner lower gear 309 is rotatably installed on the movable frame 306. An outer lower gear 308 is fixedly installed on the inner lower gear 309. An outer rotating plate 310 is rotatably installed on the outer lower gear 308. The sliding gear 307 meshes with the inner lower gear 309. An upper gear 311 is rotatably installed on the outer rotating plate 310. An outer transmission belt 313 is wound around the upper gear 311 and the outer lower gear 308. An inner rotating rod 312 is rotatably installed on the outer rotating plate 310. The upper gear 311 is rotatably installed on the inner rotating rod 312. A lower gear 314 is rotatably installed on the inner rotating rod 312. An inner transmission belt 315 is wound around the upper gear 311 and the lower gear 314. A friction wheel 316 is fixedly installed on the lower gear 314. The friction wheel 316 is rotatably installed on the cutting plate 305.

[0043] By rotating the handle 303, the handle 303 can be driven to rotate through gear transmission, thereby driving the movable frame 306 to slide along the fixed frame 203, so as to adjust the position of the movable frame 306 and the cutting length of the paper tube. The movable frame 306 slides along the rotating column 211, and the sliding gear 307 always remains meshed with the inner lower gear 309.

[0044] When the pressing frame 301 descends, it drives the pressing frame 304 to descend. The spring between the pressing frame 304 and the movable frame 306 is compressed. The spring between the pressing frame 304 and the cutting plate 305 drives the cutting plate 305, the tool rest 318, the rotating saw blade 317 and the friction wheel 316 to descend. The descent of the friction wheel 316 causes the inner rotating rod 312 to rotate relative to the outer rotating plate 310, and the outer rotating plate 310 rotates relative to the lower outer gear 308. The rotating column 211 drives the sliding gear 307 to rotate, driving the lower inner gear 309 and the lower outer gear 308 to rotate. The upper gear 311 is driven to rotate through the outer transmission belt 313, and the lower gear 314 and the friction wheel 316 are driven to rotate through the inner transmission belt 315. When the friction wheel 316 contacts the paper tube, the pressing frame 304 continues to descend, then the spring between the pressing frame 304 and the cutting plate 305 is stretched, which can adapt to paper tubes of different diameters. At the same time, the friction wheel 316 is pressed tightly on the surface of the paper tube. At this time, the rotating saw blade 317 rotates to cut the paper tube, and at the same time, the friction wheel 316 rotates to drive the paper tube to rotate itself, realizing the efficient slitting of the paper tube.

[0045] The working principle of a paper tube slitting and palletizing device disclosed by the present invention is as follows: The motor 208 drives the transmission column 202 to rotate, and drives all the slow wheels 209 and fast wheels 210 to rotate through belt transmission. The transmission ratio of the transmission belt driving the slow wheel 209 is greater than that of the transmission belt driving the fast wheel 210. The rotation speed of the fast wheel 210 is greater than that of the slow wheel 209. At the same time, the transmission column 202 drives the small cam 204 and the large cam 205 to rotate synchronously through belt transmission. The transmission column 202 drives the semi-tooth gear 108 to rotate through belt transmission. The fast wheel 210 drives the rotating column 211 to rotate through gear transmission and belt transmission. When in use, the paper tube to be cut is placed into the placing box 212, and then the paper tube enters the conveying bracket 201. The paper tube is conveyed to the blocking plate 206 by the slow wheel 209. When the large cam 205 rotates to the large radius area and contacts the pressing column 207, it will press down the pressing column 207 and the blocking plate 206. The blocking plate 206 blocks the paper tube, and the spring between the pressing column 207 and the conveying bracket 201 is compressed. At this time, the small cam 204 has not yet pressed down the pressing frame 301. The conversion area of the small cam 204 contacts the pressing frame 301 and begins to gradually press down the pressing frame 301. When the large cam 205 and the small cam 204 continue to rotate a quarter of a circle, the blocking plate 206 remains pressed down. The large radius area of the small cam 204 contacts the pressing frame 301, and the small cam 204 completes pressing down the pressing frame 301. The spring between the pressing frame 301 and the conveying bracket 201 is compressed. When the pressing frame 301 descends, it drives the pressing frame 304 to descend, and the spring between the pressing frame 304 and the movable frame 306 is compressed. The spring between the pressing frame 304 and the cutting plate 305 drives the cutting plate 305, the tool holder 318, the rotating saw blade 317 and the friction wheel 316 to descend. The descent of the friction wheel 316 causes the inner rotating rod 312 to rotate relative to the outer rotating plate 310, and the outer rotating plate 310 rotates relative to the lower outer gear 308. The rotating column 211 drives the sliding gear 307 to rotate, drives the lower inner gear 309 and the lower outer gear 308 to rotate, drives the upper gear 311 to rotate through the outer transmission belt 313, and drives the lower gear 314 and the friction wheel 316 to rotate through the inner transmission belt 315. When the friction wheel 316 contacts the paper tube, the pressing frame 304 continues to descend, then the spring between the pressing frame 304 and the cutting plate 305 is stretched, which can adapt to paper tubes of different diameters, and at the same time makes the friction wheel 316 press tightly on the surface of the paper tube. At this time, the rotating saw blade 317 rotates to cut the paper tube, and at the same time the friction wheel 316 rotates to drive the paper tube to rotate itself, realizing efficient slitting of the paper tube. Subsequently, the small radius area of the small cam 204 begins to contact the pressing frame 301, and the small radius area of the large cam 205 begins to contact the pressing column 207. The blocking plate 206 and the pressing frame 301 rise simultaneously under the action of spring reset. The fast wheel 210 quickly conveys the cut paper tube to the palletizing box 101, and the slow wheel 209 continues to convey the paper tube to be cut towards the blocking plate 206.The slit paper tubes finally enter the palletizing box 101 and slide along the slope inside the palletizing box 101 to above the lifting plate 102. When the lifting plate 102 is in a horizontal state, the blocking spring 106 is in a compressed state. When the half-tooth gear 108 meshes with the palletizing gear 107, it drives the palletizing gear 107 and the lifting plate 102 to rotate. When the lifting plate 102 rotates, it will lift the paper tubes located on it together. The torsion spring between the lifting plate 102 and the palletizing box 101 is twisted. The elastic force of this torsion spring is greater than the elastic force of the blocking spring 106, causing the paper tubes to gradually reach an upright state. Finally, the paper tubes fall onto the opening and closing plate 103. When the paper tubes are upright, their gravity presses the opening and closing plate 103 to rotate, and the torsion spring between the opening and closing plate 103 and the lifting plate 102 is twisted. Subsequently, the paper tubes fall vertically into the placement box 109 below. When the paper tubes fall out, the torsion spring between the opening and closing plate 103 and the lifting plate 102 rebounds and resets. When the lifting plate 102 rotates up, the blocking spring 106 resets, causing the lifting plate 104 and the blocking block 105 to rise. The blocking block 105 blocks the subsequent paper tubes. When the palletizing gear 107 disengages from the half-tooth gear 108, the torsion spring between the lifting plate 102 and the palletizing box 101 rebounds, causing the lifting plate 102 to reset and press the lifting plate 104 down again. The blocking spring 106 is compressed, and the blocking block 105 retracts. The subsequent paper tubes in the palletizing box 101 roll onto the lifting plate 102, and so on. There are several stacking spaces in the placement box 109. The paper tubes slide along the lifting plate 102 into the stacking spaces of the placement box 109. Subsequently, the conveyor belt 111 drives the pallet 110 and the placement box 109 to move, moving the placement box 109 along the aisle of the three-dimensional warehouse to the designated three-dimensional warehouse location. Subsequently, through equipment such as a robotic arm, the placement box 109 is stacked in the three-dimensional warehouse. The empty placement box 109 can be placed on the pallet 110, and the conveyor belt 111 drives the placement box 109 to move to the lifting plate 102 again for paper tube palletizing.
