Description

Technical Field

[0001] This application relates to the field of paper product printing technology, specifically to a paper roller transfer device. Background Technology

[0002] In the printing industry, a type of inner packaging paper for cigarette boxes is produced by directly unwinding a roll of paper, printing it, and then winding it again to obtain a roll of packaging paper rollers. The width of the paper rollers needs to be cut using edge trimming equipment to meet different production size requirements. The paper rollers are very large, and they are usually transported in the workshop using trolleys. When installing the paper rollers onto the paper cutter, the installation is inconvenient due to their large weight.

[0003] An existing patent (publication number: CN217437556U) discloses a transfer device for removing film from cardboard, which includes a support assembly and a transfer assembly. The support assembly includes a frame and a horizontal guide rail, with the guide rail fixedly mounted on the frame. The transfer assembly is mounted on the guide rail and is movable along the length of the guide rail. The transfer assembly has two fixing components, each comprising two semi-circularly shaped fixing members hinged together with their openings facing each other. One fixing member is connected to the transfer assembly, and the end of the fixing member away from the hinge point extends in a direction away from the hinge point, forming a clamping part. A bolt passes between the clamping parts of the two fixing members, and a nut is threaded onto the bolt. This device reduces the possibility of the film roller falling off.

[0004] The aforementioned device fixes the roller body with a fixing component, thereby completing the roller body transfer operation. However, the length of the cantilever beam in the aforementioned device is fixed and cannot be adjusted according to the length of the roller body. It can only complete the transfer operation of roller bodies of a specific length. Moreover, bolts, nuts and screws are required to position the roller body, which is relatively laborious and affects the work efficiency. Utility Model Content

[0005] In view of the shortcomings of the prior art, this application provides a paper roller transfer device, which has the advantages of being able to adjust the extension length of the telescopic arm according to the length of the paper roller, completing the transfer operation of paper rollers of different lengths, facilitating the positioning of the paper roller, reducing the workload of workers, and improving work efficiency, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this application provides the following technical solution: a paper roller transfer device, including a suspension beam, a bidirectional lead screw rotatably connected inside the suspension beam, two telescopic arms threadedly connected to the outer circumference of the bidirectional lead screw, a connecting rod fixedly connected to the bottom surface of each telescopic arm, a positioning frame fixedly connected to the bottom of the connecting rod, a unidirectional lead screw rotatably connected inside each positioning frame, a threaded tube threadedly connected to the outer circumference of the unidirectional lead screw, a lifting plate fixedly connected to the bottom surface of the threaded tube, a slidably connected outer surface of the lifting plate to the inner wall of the positioning frame, a positioning plate fixedly connected to the bottom of the lifting plate, and a positioning groove provided at the bottom of each positioning frame.

[0007] To further optimize the transfer effect of the rollers, improve the flexibility and practicality of the transfer device, and save manpower, the first motor drives the bidirectional screw to rotate under the action of the belt and pulley, enabling the telescopic arm to move and extend. The extension length of the telescopic arm can be adjusted according to the length of the paper roller to complete the transfer operation of paper rollers of different lengths, thus improving the flexibility and practicality of the transfer device. By rotating the unidirectional screw, the threaded tube is driven to move downward, causing the lifting plate to move downward along with the positioning plate, thereby fixing and pressing the end of the paper roller in the positioning groove, facilitating the positioning of the paper roller, reducing the workload of workers, and improving work efficiency.

[0008] Furthermore, both the positioning plate and the positioning groove are arc-shaped structures, and anti-slip pads are fixedly connected to the arc-shaped inner walls of both the positioning plate and the positioning groove.

[0009] The above scheme uses an arc-shaped design for the positioning plate and positioning groove, which can better fit the cylindrical outer surface of the paper roller end, increase the contact area, and improve the positioning stability of the paper roller. The anti-slip pad on the arc-shaped inner wall can further increase the friction between the paper roller and the roller, preventing the paper roller from sliding or falling during the transfer process and ensuring the safety and reliability of the transfer process.

[0010] Furthermore, a base plate is fixedly connected to the bottom surface of the cantilever beam, and a first motor is provided on the upper surface of the base plate. The output end of the first motor is connected to the bidirectional lead screw through a pulley and belt drive.

[0011] The above scheme utilizes pulleys and belts to achieve a transmission connection between the output end of the first motor and the bidirectional lead screw, enabling the first motor to stably drive the bidirectional lead screw to rotate, thereby driving the telescopic arm to move. This allows the paper roller transfer device to adapt to paper rollers of different widths, improving the versatility and automation of the device, and making operation more convenient and efficient.

[0012] Furthermore, each of the telescopic arms has two guide plates fixedly connected to its outer circumference, and the cantilever beam has four first guide holes inside, with the guide plates slidably connected to the cantilever beam through the first guide holes.

[0013] Through the above scheme, the cooperation between the guide plate and the first guide hole provides guidance for the movement of the telescopic arm, ensuring that the telescopic arm can move smoothly and accurately under the drive of the bidirectional screw, thereby improving the stability and accuracy of the device operation.

[0014] Furthermore, a limiting block is fixedly connected to the end of each guide plate away from the end of the cantilever beam, and two limiting plates are fixedly connected to the end of each cantilever beam.

[0015] Through the above scheme, the cooperation of the limit block and the limit plate can limit the movement range of the telescopic arm, prevent the telescopic arm from exceeding the safe stroke during movement and falling off the double-acting screw, avoid damage to the device or safety accidents caused by excessive movement, and enhance the safety and reliability of the device.

[0016] Furthermore, two guide blocks are fixedly connected to the outer surface of each of the lifting plates, and two second guide holes are opened inside each of the positioning frames. The guide blocks are slidably connected to the positioning frames through the second guide holes.

[0017] Through the above scheme, the cooperation of the guide block and the second guide hole provides guidance for the lifting movement of the lifting plate, ensuring that the lifting plate can rise and fall smoothly and vertically under the drive of the unidirectional screw, avoiding tilting or jamming of the lifting plate during the lifting process, and improving the positioning accuracy of the positioning plate for the paper roller and the stability of the device operation.

[0018] Furthermore, a lifting assembly is provided above the suspension beam. The lifting assembly is an electric hoist and is connected to the suspension beam via a hook.

[0019] With the above solution, the electric hoist can easily raise and lower the suspended beam, thereby driving the paper roller to move up and down and complete the paper roller transfer operation.

[0020] Furthermore, a moving component is fixedly connected to the top of the lifting component. The moving component includes a moving frame, a second motor is provided on the outer surface of the moving frame, a gear is fixedly connected to the output end of the second motor, four rollers are provided at the top of the moving frame, a guide rail is provided at the top of the moving component, the rollers are located inside the guide rail, a rack is fixedly connected to the bottom surface of the guide rail, the gear meshes with the rack, and a support plate is provided below the guide rail, the support plate is fixedly connected to the guide rail through a bracket.

[0021] With the above scheme, the support plate is fixedly connected to the guide rail through the bracket, which can provide stable support for the guide rail and the entire device. The second motor can be started to drive the gear and rack to mesh, thereby making the moving frame move on the guide rail under the action of the rollers, and completing the moving and transferring operation of the paper roller.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] This paper roll transfer device uses a first motor to drive a bidirectional lead screw to rotate under the action of a belt and pulley, which causes the telescopic arm to move and extend. The extension length of the telescopic arm can be adjusted according to the length of the paper roll to complete the transfer operation of paper rolls of different lengths, improving the flexibility and practicality of the transfer device. By rotating the unidirectional lead screw to drive the threaded tube to move downward, the lifting plate will drive the positioning plate to move downward, thereby fixing and pressing the end of the paper roll in the positioning groove, which facilitates the positioning of the paper roll, reduces the workload of workers, and improves work efficiency.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] Please see Figure 2 , Figure 3 and Figure 5The paper roller transfer device in this embodiment includes a suspension beam 1. A bidirectional lead screw 2 is rotatably connected inside the suspension beam 1. Two telescopic arms 3 are threadedly connected to the outer circumference of the bidirectional lead screw 2. A connecting rod 4 is fixedly connected to the bottom surface of each telescopic arm 3. A positioning frame 5 is fixedly connected to the bottom of the connecting rod 4. A unidirectional lead screw 6 is rotatably connected inside each positioning frame 5. A threaded tube 7 is threadedly connected to the outer circumference of the unidirectional lead screw 6.

Anti-slip pads are fixedly connected to the arc-shaped inner walls of both the positioning plate 9 and the positioning groove 10. The arc-shaped design of the positioning plate 9 and the positioning groove 10 can better fit the cylindrical outer surface of the paper roller end, increase the contact area, and improve the positioning stability of the paper roller. The anti-slip pads on the arc-shaped inner walls can further increase the friction between the paper roller and the roller, prevent the paper roller from sliding or falling during the transfer process, and ensure the safety and reliability of the transfer process.

[0034] Please see Figure 1 , Figure 2 and Figure 3 A base plate 11 is fixedly connected to the bottom surface of the cantilever beam 1. A first motor 12 is installed on the upper surface of the base plate 11. The output end of the first motor 12 is connected to the bidirectional lead screw 2 through a pulley and belt drive. The pulley and belt drive the output end of the first motor 12 to drive the bidirectional lead screw 2 to rotate stably, thereby driving the telescopic arm 3 to move. This enables the paper roller transfer device to adapt to paper rollers of different widths, improves the versatility and automation of the device, and makes the operation more convenient and efficient.

[0035] Please see Figure 2 and Figure 3 Each telescopic arm 3 has two guide plates 13 fixedly connected to its outer circumference. The cantilever beam 1 has four first guide holes 14. The guide plates 13 are slidably connected to the cantilever beam 1 through the first guide holes 14. The cooperation between the guide plates 13 and the first guide holes 14 provides guidance for the movement of the telescopic arm 3, ensuring that the telescopic arm 3 can move smoothly and accurately under the drive of the bidirectional screw 2, thereby improving the stability and accuracy of the device operation.

[0036] Please see Figure 2 and Figure 3Each guide plate 13 is fixedly connected to a limiting block 15 at the end away from the end of the cantilever beam 1. Two limiting plates 16 are fixedly connected to the end of the cantilever beam 1.

[0037] Please see Figure 2 and Figure 5 Two guide blocks 17 are fixedly connected to the outer surface of each lifting plate 8, and two second guide holes 18 are opened inside each positioning frame 5. The guide blocks 17 are slidably connected to the positioning frame 5 through the second guide holes 18. The cooperation of the guide blocks 17 and the second guide holes 18 provides guidance for the lifting movement of the lifting plate 8, ensuring that the lifting plate 8 can rise and fall smoothly and vertically under the drive of the unidirectional screw 6, avoiding tilting or jamming of the lifting plate 8 during the lifting process, and improving the positioning accuracy of the positioning plate 9 for the paper roller and the stability of the device operation.

[0038] Please see Figure 1 A lifting assembly 19 is provided above the suspension beam 1. The lifting assembly 19 is an electric hoist. The lifting assembly 19 is connected to the suspension beam 1 through a hook. The electric hoist can easily lift and lower the suspension beam 1, thereby driving the paper roller to move up and down and completing the paper roller transfer operation.

[0039] Please see Figure 1 and Figure 4 The top of the lifting assembly 19 is fixedly connected to a moving assembly 20. The moving assembly 20 includes a moving frame 2001. A second motor 2002 is provided on the outer surface of the moving frame 2001. A gear 2003 is fixedly connected to the output end of the second motor 2002. Four rollers 2004 are provided on the top of the moving frame 2001. A guide rail 21 is provided on the top of the moving assembly 20. The rollers 2004 are located inside the guide rail 21. A rack 22 is fixedly connected to the bottom surface of the guide rail 21. The gear 2003 meshes with the rack 22. A support plate 23 is provided below the guide rail 21. The support plate 23 is fixedly connected to the guide rail 21 through a bracket. The support plate 23 provides stable support for the guide rail 21 and the entire device. The second motor 2002 can be started to drive the gear 2003 to mesh with the rack 22, thereby causing the moving frame 2001 to move on the guide rail 21 under the action of the rollers 2004, thus completing the moving and transferring operation of the paper roller.

[0040] In this embodiment, the paper roller transfer device uses a first motor 12 to drive a bidirectional lead screw 2 to rotate under the action of a belt and pulley, which causes the telescopic arm 3 to move and extend. The extension length of the telescopic arm 3 can be adjusted according to the length of the paper roller to complete the transfer operation of paper rollers of different lengths, thereby improving the flexibility and practicality of the transfer device. By rotating a unidirectional lead screw 6, the threaded tube 7 is driven to move downward, causing the lifting plate 8 to drive the positioning plate 9 to move downward, thereby fixing and pressing the end of the paper roller in the positioning groove 10, which facilitates the positioning of the paper roller, reduces the workload of workers, and improves work efficiency.

[0041] It should be noted that a handwheel is provided at the top of the one-way lead screw 6.

[0042] The working principle of the above embodiments is as follows:

[0043] The horizontal lifting and lowering can be adjusted by an electric hoist. The second motor 2002 can be started to drive the gear 2003 to mesh with the rack 22, thereby causing the moving frame 2001 to move on the guide rail 21 under the action of the roller 2004. This drives the lifting assembly 19 and the suspension beam 1 to move laterally. When the paper roller is being transferred, the first motor 12 is started to drive the bidirectional lead screw 2 to rotate under the action of the belt and pulley. The bidirectional lead screw 2 drives the telescopic arm 3 to move and retract. The telescopic arm 3, through the connecting rod 4, drives the positioning frame 5 to move and retract, making the spacing between the positioning frames 5 slightly larger. Based on the length of the paper roller, the suspension beam 1 is driven down by an electric hoist, causing the positioning frame 5 to move down to both sides of the paper roller end. Then, the first motor 12 is started, causing the positioning frame 5 to move inward and fit over the end of the paper roller, so that the end of the paper roller is located inside the positioning groove 10. Finally, the one-way screw 6 is rotated to drive the threaded tube 7 to move down. The threaded tube 7 drives the positioning plate 9 to move down through the lifting plate 8. The positioning plate 9 presses and fixes the end of the paper roller inside the positioning groove 10, completing the positioning of the paper roller. Finally, the paper roller can be transferred by the lifting assembly 19 and the moving assembly 20.
