[0029] To make the purposes, technical solutions and advantages of the embodiments of the present disclosure clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present disclosure with reference to the accompanying drawings in the embodiments of the present disclosure. Apparently, the described embodiments are some but not all of the embodiments of the present disclosure. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present disclosure without creative efforts shall fall within the protection scope of the present disclosure. It should be noted that, without conflict, the embodiments in the present disclosure and the features in the embodiments may be combined with each other arbitrarily.

[0030] As described in the background art, in the yarn cake packaging process, the paper winding tube in the yarn cake needs to be taken out and reused. Currently, during the packaging process, after manually taking out the winding tube in the yarn cake, the paper winding tube is sorted and packed. Since the paper winding tube has been shaped into a cylindrical or arc-shaped tube after the previous baking process, there are problems of high labor intensity and low production efficiency in the manual processing of its recycling, sorting and space compression.

[0031] Based on this, the present disclosure provides a paper tube stacking, pressing and strapping device. Through the stacking and pressing mechanism, the paper tubes can be sent to the first position, and the limiting assembly limits the movement range of the paper tubes at the first position. When the number of paper tubes at the first position reaches the preset value or is controlled by manual intervention, the strapping mechanism moves the strapping device to the first position and uses the strapping device to gather and fix the paper tubes into a whole, and then through the pushing-out mechanism, the gathered and fixed paper tubes together with the strapping device are moved to the second position, realizing the collection, packing and transfer of the paper tubes, reducing the proportion of manual participation in the paper tube packing and transfer process, reducing the labor intensity of the operator, and at the same time being able to form an automated packing and transfer system, improving work efficiency and liberating productivity.

[0032] In an exemplary embodiment of the present disclosure, a paper tube stacking, pressing and strapping device is provided, as Figure 1 shown Figure 1 is a schematic structural diagram of a paper tube stacking, pressing and strapping device shown according to an exemplary embodiment;Figure 2 It is a schematic diagram of the position of the feeding port shown according to an exemplary embodiment; Figure 3 It is a schematic diagram of the structures of the stacking mechanism, the bundling mechanism, and the pushing mechanism shown according to an exemplary embodiment; Figure 4 It is a schematic diagram of the limiting component shown according to an exemplary embodiment; Figure 5 It is a schematic diagram of the bundler shown according to an exemplary embodiment; Figure 6 It is a schematic diagram of the pushing mechanism shown according to an exemplary embodiment. The following is introduced in conjunction with Figures 1 to 6 this.

[0033] Some specific implementation manners described below are intended to facilitate those skilled in the art to understand this embodiment, and this embodiment is not limited by some specific implementation manners described below.

[0034] Referring to Figure 1 and Figure 3 A paper tube stacking and bundling device provided by an exemplary embodiment of the present disclosure, the paper tube stacking and bundling device includes a frame 1, and a stacking mechanism 2, a bundling mechanism 3, and a pushing mechanism 4 provided on the frame 1.

[0035] The stacking mechanism 2 includes a pushing and pressing component 21 for transferring a paper tube (not shown in the figure) to the first position 12, and a limiting component 22 for preventing the paper tube from detaching from the first position 12 in the direction of the pushing and pressing component 21.

[0036] The bundling mechanism 3 includes a bundler 31 for simultaneously fixing a plurality of paper tubes, and a pushing component 33 for transferring the bundler 31 to the first position 12 and enabling the bundler 31 to simultaneously surround a plurality of paper tubes.

[0037] The pushing mechanism 4 includes a conveying component 41 for transferring the paper tube surrounded by the bundler 31 to the second position, and a lifting component 42 for transferring the conveying component 41 to the first position 12, and the first position 12 is different from the second position.

[0038] Exemplarily, referring to Figure 1 and Figure 3, the pushing mechanism 4, the strapping mechanism 3, and the stacking mechanism 2 are vertically distributed from bottom to top. The number of the strapping mechanisms 3 is two and they are relatively distributed. The first position 12 is located between the two strapping mechanisms 3. Above the first position 12 is the stacking mechanism 2, and below the first position 12 is the pushing mechanism 4. The limiting component 22 and the pushing component 21 are vertically distributed from bottom to top. The pushing component 21 pushes the paper tube through the limiting component 22 and into the first position 12 by moving in the direction towards the limiting component 22. The pushing component 21 forms a new paper tube input space by moving in the direction away from the limiting component 22, and repeats the above process to make the paper tube enter the first position 12. The continuously stacked paper tubes in the first position 12 come into contact with the limiting component 22 as the overall height increases, and are blocked by the limiting component 22 and stay in the first position 12 below the limiting component 22, and are further stacked and compressed as the pushing component 21 pushes a new paper tube.

[0039] The two relatively arranged strapping mechanisms 3 are respectively arranged on the opposite sides of the first position 12. The pushing component 33 is located on the side of the strapping device 31 away from the first position 12. The power output end of the pushing component 33 is connected to the strapping device 31 and pushes the strapping device 31 to move towards the first position 12, so that the strapping device 31 surrounds the stacked and compressed paper tubes. The pushing component 33 is disconnected from the strapping device 31, so as to realize fixing the stacked and compressed paper tubes by the strapping device 31 to form an integral that can be transported separately.

[0040] The lifting component 42 and the conveying component 41 are vertically distributed from bottom to top. The power output end of the lifting component 42 is connected to the conveying component 41. The lifting component 42 drives the conveying component 41 to move vertically. When the conveying component 41 moves to the first position 12, the paper tube abuts against the power output end of the conveying component 41. The paper tube surrounded and fixed by the strapping device 31 is moved out of the first position 12 through the conveying component 41 and into the second position. The second position can be other areas outside the frame, or a certain position set inside the frame according to the subsequent process requirements. The second position is not specifically limited.

[0041] In this embodiment, the stacking mechanism 2 can move the paper tube over the limiting component 22 and transfer it to the first position 12. The limiting component 22 limits the movement range of the paper tube at the first position 12. When the number of paper tubes at the first position 12 reaches the preset value or is controlled by manual intervention, the strapping mechanism 3 transfers the strapping device 31 to the first position 12 and fixes the paper tubes together as a whole by the strapping device 31, and transfers the gathered and fixed paper tubes together with the strapping device 31 to the second position through the pushing mechanism 4, realizing the collection, packing and transportation of the paper tubes, reducing the proportion of manual participation in the process of packing and transporting the paper tubes, reducing the labor intensity of the operator, and at the same time being able to form an automatic packing and transportation system, improving the work efficiency and liberating the productive forces.

[0042] In this embodiment, with reference to Figure 3 , the pressing assembly 21 includes a pressing cylinder 211 fixed to the frame 1 above the feeding port 11, and a pressing plate 212 fixed to the end of the piston rod of the pressing cylinder 211. The cylinder block of the pressing cylinder 211 is fixedly connected to the frame 1. The frame 1 at the pressing assembly 21 is in a box shape. The piston rod of the pressing cylinder 211 extends vertically downward into the frame 1. The pressing plate 212 is horizontally arranged and fixed to the end of the piston rod of the pressing cylinder 211 located inside the frame 1. The two ends of the pressing plate 212 are warped upward to prevent the sharp edge of the pressing plate 212 from getting stuck inside the compressed and deformed paper tube, causing the problem that the paper tube is lifted when the pressing plate 212 moves upward and resets. A feeding port 11 for feeding the paper tube is formed in the frame 1. The power output end of the pressing cylinder 211 extends into the frame 1. When the power output end of the pressing cylinder 211 retracts to the maximum extent, the feeding port 11 is completely exposed, and at this time, the feeding of the paper tube is not hindered by the pressing assembly 21.

[0043] In other embodiments, with reference to Figure 3 , a horizontally arranged connecting plate 215 is fixedly connected to the end of the piston rod of the pressing cylinder 211 located inside the frame 1. Two pressing plates 212 are respectively connected to the two ends of the connecting plate 215, and both of the two pressing plates 212 are horizontally arranged. The piston rod of the pressing cylinder 211 is fixedly connected to the center position of the connecting plate 215. Guide rods 213 are fixedly connected to the connecting plate 215 on both sides of the piston rod of the pressing cylinder 211. The guide rods 213 are vertically arranged and penetrate upward through the frame 1. A guide sleeve 214 adapted to the guide rod 213 is fixed at the connection of the frame 1 and the guide rod 213. The bottom end of the guide sleeve 214 is fixedly connected to the frame 1. The guide sleeve 214 sleeves on the part of the guide rod 213 extending outside the frame 1 and is slidably connected to the guide rod 213.

[0044] The connecting plate 215 can increase the number of pressing plates 212 for compressing the paper tube, increase the extrusion area of the paper tube, so that the paper tube can be compressed to a greater extent and the volume of the paper tube is reduced. The guide rods 213 can balance the forces at both ends of the connecting plate 215 and reduce the possibility that the connecting plate 215 is stressed and skewed due to the uneven top surface of the paper tube during the process of the pressing plate 212 squeezing the paper tube.

[0045] In an exemplary embodiment of the present disclosure, with reference to Figure 3 and Figure 4 , the limiting assembly 22 includes a limiting plate 221 movably connected to the frame 1, and a limiter 222 fixedly connected to the limiting plate 221. The limiting plate 221 is configured to open towards the first position 12, and the limiter 222 is configured to prevent the limiting plate 221 from opening in the direction away from the first position 12.

[0046] Exemplarily, with reference to Figure 3 andFigure 4 The limiting component 22 is arranged inside the frame 1 below the pressing component 21. The stopper 222 is fixed to both the limiting plate 221 and the frame 1 at the same time. The projection of the limiting plate 221 in the vertical direction is staggered with the pressing plate 212. The limiting plate 221 is in the open state when it rotates towards the first position 12 to form a space for the paper tube to pass above the first position 12. The limiting plate 221 is horizontally placed above the first position 12 and obstructs the paper tube from directly falling into the first position 12 or separating upward from the first position 12, which is the closed state. The stopper 222 applies a force to reset the limiting plate 221 from the open state to the closed state, and the stopper 222 limits the movement range of the limiting plate 221 to only between the open state and the closed state.

[0047] In this embodiment, after the paper tube is put into the frame 1 from the feeding port 11, it will directly fall on the limiting plate 221. The limiting plate 221 is kept in the closed state under the action of the stopper 222. When the pressing component 21 moves from top to bottom, while the pressing component 21 presses the paper tube, it also applies a force to the limiting plate 221. Under the downward pressure of the pressing component 21, the limiting plate 221 overcomes the force of the stopper 222, and the limiting plate 221 changes from the closed state to the open state. When the limiting plate 221 is in the open state, the paper tube loses the support at the bottom and falls into the first position 12 under the downward pressure of the pressing component 21. After the pressing component 21 completes one-time pressing of the paper tube, it resets. The limiting plate 221 also resets from the open state to the closed state under the action of the stopper 222. As the number of paper tubes in the first position 12 increases, the stacked paper tubes continuously increase in height. Although the stacked paper tubes can be compressed under the downward pressure of the pressing component 21, when the pressure of the pressing component 2 is removed, the stacked paper tubes will expand to a certain extent due to the material. The expanded paper tubes will approach or even abut against the limiting plate 221. The stopper 222 can limit the movement of the limiting plate 221 only between the open state and the closed state, that is, it can provide a limit to the expanded paper tubes, reduce the possibility of the paper tubes separating upward from the first position 12, enable the paper tubes to be stably packed, and reduce the influence on the subsequent feeding and compression of the paper tubes.

[0048] In an exemplary embodiment of the present disclosure, referring to Figure 3 and Figure 4 the limiting plate 221 is rotatably connected to the frame 1. A first preset angle is provided between the rotation axis of the limiting plate 221 and the pressing direction of the pressing component 21. The stopper 222 includes a torsion spring fixed to the limiting plate 221, and the torsion spring is used to drive the limiting plate 221 to return from the open state facing the first position 12 to the closed state.

[0049] Exemplarily, referring to Figure 3 and Figure 4, the limiting plate 221 includes a limiting block 2211 fixedly connected to the frame 1 and a baffle 2212 hinged to the limiting block 2211. The rotation axis of the baffle 2212 is horizontally arranged, and the first preset angle is 90°. Two baffles 2212 are arranged on the same limiting block 2211, and the two baffles 2212 are respectively arranged at both ends of the limiting block 2211. One end of the torsion spring serving as the limiter 222 is fixedly connected to the limiting block 2211, and the other end is fixedly connected to the baffle 2212. Two torsion springs are arranged on the same limiting block 2211, and the two torsion springs are respectively arranged on the top surface and the bottom surface of the limiting block 2211. Each torsion spring corresponds to a baffle 2212. When the torsion spring is in the natural state, the baffle 2212 is in a horizontal and straight posture.

[0050] In this embodiment, the baffle 2212 can maintain a horizontal and straight posture under the action of the torsion spring. The paper tube is pressed down by the pressing assembly 21 and passes through the baffle 2212 into the first position 12, and is compressed under the action of the pressing assembly 21. Under the action of the torsion spring, the baffle 2212 can be reset together every time the pressing assembly 21 resets. As more and more paper tubes are compressed and stacked at the first position 12, the paper tubes will gradually approach or even abut against the baffle 2212. Since the torsion spring limits that the baffle 2212 can only rotate between straight and vertical, the baffle 2212 can apply a limiting effect on the stacked and compressed paper tubes, reducing the possibility that the number of paper tubes is too large or they invade the space above the baffle 2212 due to their own expansion and even overflow from the feeding port 11, and reducing the impact on subsequent feeding.

[0051] In an exemplary embodiment of the present disclosure, refer to Figure 3 and Figure 5 , the bundler 31 includes a pressing arm 311 for abutting against the outer wall of the paper tube and a fixed arm 312 for abutting against the outer wall of the paper tube. A second preset angle is provided between the pressing arm 311 and the fixed arm 312, and the area between the pressing arm 311 and the fixed arm 312 forms an embracing space for accommodating the paper tube.

[0052] Exemplarily, refer to Figure 3 and Figure 5 , one end of the pressing arm 311 is fixed to one end of the fixed arm 312, the pressing arm 311 extends towards the first position 12, and the second preset angle is 90°. There are multiple bundlers 31, and the bundlers 31 are grouped in pairs and embrace the paper tube from both sides of the arc-shaped side wall of the paper tube. Both the pressing arm 311 and the fixed arm 312 abut against the arc-shaped side wall of the paper tube.

[0053] In this embodiment, due to the elasticity of the pressing arm 311 and the fixing arm 312 themselves, the pressing arm 311 and the fixing arm 312 are abutted against the paper tube and surround the paper tube. The friction between the paper tube and the bundling device 31 maintains the stability of their connection. Two or two groups of bundling devices 31 respectively arranged on both sides of the paper tube further improve the bundling and fixing effect of the paper tube, so that the compressed and stacked paper tubes can be fixed by the bundling device 31 to form a whole, completing the packing operation, and can be integrally transferred from the first position 12 to the second position by the conveying assembly 41, reducing the possibility of the stacked paper tubes collapsing and scattering during the transfer process.

[0054] In an exemplary embodiment of the present disclosure, referring to Figure 3 and Figure 5 , the number of the pressing arms 311 is two and they are respectively arranged at both ends of the fixing arm 312. The two pressing arms 311 both extend towards the first position 12, and the end of the pressing arm 311 far from the fixing arm 312 is bent backwards. The bundling device 31 is in a C shape with an open and expanding opening.

[0055] Exemplarily, referring to Figure 3 and Figure 5 , pressing arms 311 are fixedly connected to both ends of the fixing arm 312. The two pressing arms 311 connected to the same fixing arm 312 extend in the same direction. An opening for surrounding the paper tube is formed between the extending ends of the two pressing arms 311. The bundling device 31 with the opening is in a C shape. The end of the pressing arm 311 at the opening of the bundling device 31 is bent in a direction away from the opening of the bundling device 31, making the opening of the bundling device 31 in a flared shape.

[0056] In this embodiment, the combination of two pressing arms 311 and one fixing arm 312 forms a C-shaped bundling device 31. The bundling device 31 surrounds the paper tube through the opening between the extending ends of the two pressing arms 311. The bending of the extending ends of the pressing arms 311 forms a guiding structure, enabling the extending ends of the pressing arms 311 to slide more easily along the side wall of the paper tube, and placing the paper tube in the surrounding space formed by the two pressing arms 311 and one fixing arm 312. Due to the friction between the pressing arm 311 and the paper tube, the pressing arm 311 stays on the side wall of the paper tube, and the pressure exerted on the paper tube due to the deformation of the pressing arm 311 and its own elasticity increases the aforementioned friction, improving the connection strength between the bundling device 31 and the paper tube, enhancing the packing and fixing effect of the bundling device 31 on the paper tube, and reducing the possibility of the stacked paper tubes collapsing and scattering during the transfer of the paper tube.

[0057] In an exemplary embodiment of the present disclosure, referring to Figure 3, there are multiple bundlers 31. The bundling mechanism 3 further includes a feeding component 32 disposed on one side of the first position 12. The feeding component 32 has a third position for accommodating the bundlers 31, and a fourth position for the bundlers 31 to enter the first position 12 from the third position. The fourth position communicates with the first position 12. The feeding component 32 includes a feeder 322, and the feeder 322 is used to transfer the bundlers 31 from the third position to the fourth position one by one.

[0058] Exemplarily, referring to Figure 3 , both the third position and the fourth position are located on one side of the first position 12, and the fourth position communicates with both the third position and the first position 12 at the same time. There are multiple bundlers 31, and the bundlers 31 are arranged in a straight line at the third position, and the openings of the bundlers 31 are all arranged facing the first position 12. The feeder 322 is fixed to the frame 1, and the power output end of the feeder 322 acts on one bundler 31 located at the end far from the third position among the bundlers 31 arranged in a straight line. The feeder 322 pushes this bundler 31 far from the third position to transfer the bundlers 31 arranged in a straight line towards the third position, so that the bundlers 31 arranged in a straight line as a whole move towards the third position until one bundler 31 close to the third position among the bundlers 31 arranged in a straight line moves to the third position. The pushing component 33 is fixed to the frame 1, and the power output end of the pushing component 33 can extend into the fourth position.

[0059] In this embodiment, the feeding component 32 pushes the bundlers 31 arranged in a straight line at the third position as a whole until one bundler 31 is located at the fourth position. The power output end of the pushing component 33 extends into the fourth position and abuts against the bundler 31 located at the fourth position, and transfers the bundler 31 towards the first position 12. After the bundler 31 moves to the first position 12, it will surround the paper tube to complete the packaging and fixing of the paper tube.

[0060] In an exemplary embodiment of the present disclosure, referring to Figure 3 , the feeding component 32 includes a material box 321 disposed on one side of the first position 12. The internal space of the material box 321 forms the third position. The material box 321 is provided with a discharge port through which the bundler 31 passes and enters the first position 12. The discharge port forms the fourth position. The power output end of the feeder 322 acts on the bundler 31 inside the material box 321 and is used to transfer the bundler 31 from the third position to the fourth position.

[0061] Exemplarily, referring to Figure 3, The material box 321 is fixedly connected to the frame 1 on one side of the first position 12. The top of the material box 321 is open, and is used to place the bundler 31 in a vertical posture inside the material box 321. The bundlers 31 inside the material box 321 are distributed with two pressing arms 311 up and down and the opening faces the first position 12. The internal space of the material box 321 forms a third position and a fourth position. One end of the material box 321 is aligned with the first position 12, and the discharge port is opened on the side wall of the material box 321 facing the first position 12. The fourth position is inside the material box 321 at the discharge port, and the size of the fourth position is the same as the size of one bundler 31. The other space inside the material box 321 forms the third position. The bundler 31 leaves the third position and enters the fourth position under the action of the pushing component 33.

[0062] In this embodiment, the discharge box 321 can accommodate multiple bundlers 31 at the same time, and arrange the bundlers 31 in a straight line, reducing the possibility that the bundler 31 tilts and topples when the feeder 322 transfers the bundler 31, so that the bundler 31 can be stably transferred to the third position.

[0063] In an exemplary embodiment of the present disclosure, refer to Figure 3 , A push plate 3221 is movably connected inside the material box 321. The push plate 3221 is fixedly connected to the power output end of the feeder 322. The push plate 3221 is in abutting connection with the bundler 31. The power output end of the feeder 322 drives the push plate 3221 to transfer the bundler 31 from the third position to the fourth position.

[0064] Exemplarily, refer to Figure 3 , The feeder 322 includes a feeding cylinder fixedly connected to the frame 1. The piston rod of the feeding cylinder is arranged along the arrangement direction of the bundlers 31. The push plate 3221 is slidably connected inside the material box 321 along the arrangement direction of the bundlers 31. The side wall of the push plate 3221 abuts against the inner side wall of the material box 321. The projection of the push plate 3221 along the arrangement direction of the bundlers 31 covers the bundlers 31. The feeding cylinder is located at the bottom of the material box 321. The bottom surface of the material box 321 is provided with a through groove extending along the arrangement direction of the bundlers 31. The bottom end of the push plate 3221 extends out below the material box 321 through this through groove and is fixedly connected to the piston rod of the feeding cylinder. The push plate 3221 inside the material box 321 abuts against the bundler 31. When the piston rod of the feeding cylinder moves to the minimum stroke, the push plate 3221 pushes a bundler 31 to the third position.

[0065] In this embodiment, the feeding cylinder serving as the feeder 322 drives the pushing plate 3221 to move inside the cartridge 321 from the fourth position to the third position through the contraction of the piston rod, so that the pushing plate 3221 pushes the bundler 31 at the third position to the fourth position. The two side walls of the pushing plate 3221 are respectively abutted against the two opposite inner side walls of the cartridge 321, and the pushing plate 3221 can cover the bundler 31 at the third position in the horizontal direction, reducing the possibility that the bundler 31 is stuck between the pushing plate 3221 and the inner wall of the cartridge 321 and improving the stability of the bundler 31 moving from the third position to the fourth position. The projection of the pushing plate 3221 in the arrangement direction of the bundlers 31 covers the bundlers 31, enabling the pushing plate 3221 to abut against the bundlers 31 more comprehensively, increasing the contact area between the pushing plate 3221 and the bundlers 31, and reducing the possibility that the bundlers 31 are skewed or even toppled due to uneven force during the movement.

[0066] In an exemplary embodiment of the present disclosure, referring to Figure 3 , the pushing assembly 33 includes a pushing cylinder 331 disposed on one side of the first position 12 and a push plate 332 fixedly connected to the power output end of the pushing cylinder 331. The push plate 332 is adapted to the shape of the bundler 31. The power output end of the pushing cylinder 331 is used to move the push plate 332 and make the push plate 332 abut against the bundler 31. The pushing cylinder 331 is used to move the bundler 31 through the fourth position to leave the third position and enter the first position 12.

[0067] Exemplarily, referring to Figure 3 , the pushing cylinder 331 is fixedly connected to the frame 1 on one side of the cartridge 321. The piston rod of the pushing cylinder 331 is oriented towards the first position 12, and the piston rod of the pushing cylinder 331 is disposed opposite to the discharge port. The push plate 332 is vertically disposed and fixedly connected to the end of the piston rod of the pushing cylinder 331. The contour of the push plate 332 is adapted to the contour of the discharge port and the contour of the fixed arm 312. An opening adapted to the push plate 332 is formed in the side wall of the cartridge 321 facing away from the first position 12. The pushing cylinder 331 pushes the push plate 332 to move inside the cartridge 321. When the piston rod of the pushing cylinder 331 moves to the minimum stroke, the push plate 332 is located in the opening formed in the side wall of the cartridge 321 facing away from the first position 12, and at this time, the side wall of the push plate 332 facing the first position 12 is flush with the inner wall of the cartridge 321.

[0068] In this embodiment, the pushing plate 3221 adapted to the contour of the fixed arm 312 can abut against the bundler 31 over a larger area, maintaining the stable posture of the pushed bundler 31 when the piston rod of the feeding cylinder extends, reducing the possibility that the bundler 31 is skewed or toppled during the process from inside the cartridge 321 to being held around the paper tube, enabling the bundler 31 to be stably fixed on the paper tube, and realizing the packaging and fixing of the paper tube.

[0069] In an exemplary embodiment of the present disclosure, with reference to Figure 3 and Figure 6 , the lifting assembly 42 includes a lifting cylinder disposed below the first position 12, the conveying assembly 41 is disposed at the free end of the piston rod of the lifting cylinder, and when the piston rod of the lifting cylinder moves to the maximum stroke, the bundler 31 and / or the paper tube is located on the conveying assembly 41.

[0070] Exemplarily, with reference to Figure 3 and Figure 6 , the cylinder block of the lifting cylinder is fixed to the frame 1 below the first position 12, and the piston rod of the lifting cylinder is vertically oriented towards the first position 12. The conveying assembly 41 includes a conveyor belt fixedly connected to the top end of the piston rod of the lifting cylinder, and the top surface of the conveyor belt is the conveying surface, and this conveying surface is horizontally arranged. When the piston rod of the lifting cylinder moves to the maximum stroke, the top surface of the conveyor belt is located at the first position 12 and abuts against the paper tube.

[0071] In this embodiment, after the paper tube is packed and fixed by the bundler 31, the conveyor belt is lifted to the first position 12 by the lifting cylinder, so that the top surface of the conveyor belt abuts against the paper tube, and the paper tube at the first position 12 is transferred to a second position different from the first position 12 through the conveyor belt, reducing the degree of manual participation in the process of packing and fixing the paper tube, improving the degree of automation, and reducing the labor intensity of the operator.
