Description

Technical Field

[0001] This utility model relates to the field of printing machines, and more particularly to an alternating biaxial printing machine. Background Technology

[0002] Existing printing machines typically employ a horizontal circular layout, with multiple receiving rollers evenly distributed along the circumference. A rotating mechanism drives these rollers to sequentially switch to the printing station for continuous operation. However, this structure results in a large overall footprint and low space utilization in the production line. This significantly increases the difficulty of installation and layout, especially for small and medium-sized enterprises with limited space. Furthermore, since part of the receiving roller structure is exposed outside the frame, the rotation of the rollers may pose a safety hazard.

[0003] Based on the above, existing printing machines need further improvement. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an alternating dual-axis printing machine. The receiving rollers are respectively set on two moving components, so that the receiving rollers can exchange positions by only short-distance linear displacement, saving space. Moreover, the short-distance movement means that the exchange mechanism does not need to be exposed outside the frame, avoiding safety hazards during operation.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an alternating biaxial printing machine, including a frame, the frame including a docking part, the lower side of which forms a printing area; an exchange mechanism, the exchange mechanism being disposed on the frame, the exchange mechanism including a first moving component, a second moving component and a guide rail assembly, the first moving component being provided with a first receiving roller, the second moving component being provided with a second receiving roller, the first moving component and the second moving component exchanging positions by sliding on the guide rail assembly, so that the first receiving roller and the second receiving roller alternately enter the printing area.

[0006] This invention employs an exchange mechanism to mount the receiving rollers on two independently controlled moving components. Station switching is achieved through a short-stroke linear displacement mechanism, significantly reducing the equipment's footprint. Furthermore, because the exchange mechanism requires a short switching stroke, it can be completely integrated within the frame, avoiding exposed moving parts and fundamentally eliminating the safety hazard of operators contacting moving components, thus significantly improving the equipment's safety performance. Compared to existing technologies, this invention's alternating dual-axis printing machine has a more compact structure, saves space, and offers higher safety performance.

[0007] Preferably, the second moving component is provided with a lifting mechanism, which is used to raise or lower the second moving component.

[0008] Preferably, the first moving component is provided with a lifting mechanism, which is used to raise or lower the first moving component.

[0009] A lifting mechanism is provided on the first or second moving component to prevent cross-blocking when exchanging work positions. The first or second moving component can be raised or lowered to a different height from the other component, and then slide along the guide rail to exchange work positions, so that the first receiving roller and the second receiving roller move linearly at different heights, avoiding collision between the first receiving roller and the second receiving roller.

[0010] Preferably, the exchange mechanism further includes a base plate and a support base, the support base being disposed on the base plate, and the guide rail assembly including a first guide rail disposed on the support base and a second guide rail disposed on the base plate.

[0011] Preferably, the second moving component is disposed on the second guide rail, and the first moving component is disposed on the first guide rail with the height of the first receiving roller corresponding to the docking part, so that the first receiving roller can enter the printing area by moving horizontally.

[0012] Preferably, the first moving component is disposed on the second guide rail, and the second moving component is disposed on the first guide rail with the height of the second receiving roller corresponding to the docking part, so that the second receiving roller can enter the printing area by moving horizontally.

[0013] Preferably, the first guide rail and the second guide rail extend in a direction perpendicular to the first receiving roller or the second receiving roller.

[0014] Preferably, the base plate is provided with a second driving cylinder, which extends along the length direction of the second guide rail, and the piston of the second driving cylinder is connected to the second moving component; the support base is provided with a first driving cylinder, which extends along the length direction of the first guide rail, and the piston of the first driving cylinder is connected to the first moving component.

[0015] Preferably, the base plate is provided with a second driving cylinder, which extends along the length direction of the second guide rail, and the piston of the second driving cylinder is connected to the first moving component; the support base is provided with a first driving cylinder, which extends along the length direction of the first guide rail, and the piston of the first driving cylinder is connected to the second moving component.

[0016] Because the second guide rail is set at a lower height, while the docking part is set at a relatively higher position, the lifting mechanism allows the receiving roller to enter the printing area and reach the printing height opposite to the docking part to complete the printing. After the receiving roller is switched to the periphery of the printing area, it can also be raised by the lifting mechanism to match the operating height of the loading personnel, making the operation of the loading personnel more convenient.

[0017] When the first and second drive cylinders extend or retract, they drive the first or second moving component to slide back and forth along the first or second guide rail.

[0018] Preferably, an adjustment device is provided between the base plate and the support seat. The adjustment device is used to adjust the relative height between the support seat and the base plate, so that the height of the first receiving roller is adjustable to adapt to different material cylinder sizes.

[0019] Preferably, the frame is provided with a third guide rail, which extends along the direction of the first receiving roller or the second receiving roller, and the exchange mechanism is slidably disposed on the third guide rail to adapt to different material cylinder lengths.

[0020] Preferably, the first moving component and the second moving component are provided with a driving device, which is used to drive the first receiving roller or the second receiving roller to rotate. Attached Figure Description

[0026] In the description of this utility model, it should be understood that the orientation or positional relationship indicated by terms such as "upper", "lower", "left", "right", "horizontal", "inner", and "outer" is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing this utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.

[0027] Example 1

[0028] See Figures 1 to 3 This embodiment discloses an alternating biaxial printing machine 1, including a frame 2, the frame 2 including a docking part 21, the lower side of the docking part 21 forming a printing area 22; and an exchange mechanism 3, the exchange mechanism 3 being disposed on the frame 2, the exchange mechanism 3 including a first moving component 31, a second moving component 32 and a guide rail group 33, the first moving component 31 being provided with a first receiving roller 311, the second moving component 32 being provided with a second receiving roller 321, the first moving component 31 and the second moving component 32 exchanging positions by sliding on the guide rail group 33, so that the first receiving roller 311 and the second receiving roller 321 alternately enter the printing area 22.

[0029] The second moving component 32 is provided with a lifting mechanism 34, which is used to raise or lower the second moving component 32. In this solution, before the second receiving roller 321 moves horizontally along the second guide rail 332, the lifting mechanism 34 resets and drives the second receiving roller 321 to descend, preventing it from moving at the same height as the first receiving roller 311 and causing cross-blocking. After the second receiving roller 321 moves horizontally along the second guide rail 332, the lifting mechanism 34 extends and drives the second receiving roller 321 to rise to the printing height corresponding to the docking part 21 to complete the printing, or raises it to the loading station.

[0030] To achieve short-range linear station exchange between the first receiving roller 311 and the second receiving roller 321, the exchange mechanism 3 further includes a base plate 35 and a support base 36. The support base 36 is disposed on the base plate 35, and the guide rail assembly 33 includes a first guide rail 331 disposed on the support base 36 and a second guide rail 332 disposed on the base plate 35. Specifically, the first guide rail 331 and the second guide rail 332 extend in a direction perpendicular to either the first receiving roller 311 or the second receiving roller 321. In this design, the first guide rail 331 and the second guide rail 332 are arranged diagonally, so that the sliding heights of the first moving component 31 and the second moving component 32 are different, preventing the first receiving roller 311 and the second receiving roller 321 from intersecting during movement.

[0031] The second moving component 32 is disposed on the second guide rail 332, and the first moving component 31 is disposed on the first guide rail 331, with the height of the first receiving roller 311 corresponding to the docking part 21.

[0032] To enable the second driving cylinder 38 to reciprocate along the second guide rail 332 when it extends or resets, and to enable the first driving cylinder 37 to reciprocate along the first guide rail 331 when it extends or resets, the base plate 35 is provided with a second driving cylinder 38, which extends along the length direction of the second guide rail 332, and the piston of the second driving cylinder 38 is connected to the second moving component 32; the support base 36 is provided with a first driving cylinder 37, which extends along the length direction of the first guide rail 331, and the piston of the first driving cylinder 37 is connected to the first moving component 31.

[0033] An adjustment device 39 is provided between the base plate 35 and the support base 36. The adjustment device 39 is used to adjust the relative height between the support base 36 and the base plate 35. Specifically, the adjustment device 39 includes a jack 391 and a plurality of lifting columns 392. The jack 391 is located in the middle of the lower side of the support base 36, and the lifting columns 392 are located at the four lower corners of the support base 36.

[0034] To make the distance between the exchange mechanism 3 and the docking part 21 adjustable to accommodate different barrel lengths, a third guide rail 23 is provided on the frame 2. The third guide rail 23 extends along the direction of the first receiving roller 311 or the second receiving roller 321, and the exchange mechanism 3 is slidably mounted on the third guide rail 23.

[0035] The first moving component 31 and the second moving component 32 are provided with a driving device 310, which is used to drive the first receiving roller 311 or the second receiving roller 321 to rotate.

[0036] This invention employs an exchange mechanism 3 to separately mount the receiving rollers on two independently controlled moving components. Station switching is achieved through a short-stroke linear displacement mechanism, significantly reducing the equipment's footprint. Furthermore, because the exchange mechanism 3 requires a short switching stroke, it can be completely integrated within the frame 2, avoiding exposed moving parts and fundamentally eliminating the safety hazard of operators contacting moving components, thus significantly improving the equipment's safety performance. Compared to existing technologies, this invention's alternating dual-axis printing machine 1 has a more compact structure, saves space, and offers higher safety performance.

[0037] Example 2

[0038] This embodiment is an improvement on Embodiment 1, and the difference from Embodiment 1 is that the lifting mechanism 34 and the first moving component 31 are positioned differently (not shown in the accompanying drawings for this embodiment).

[0039] The lifting mechanism 34 is disposed on the first moving component 31, and the lifting mechanism 34 is used to raise or lower the first moving component 31.

[0040] The first moving component 31 is disposed on the second guide rail 332, and the second moving component 32 is disposed on the first guide rail 331, with the height of the second receiving roller 321 corresponding to the docking part 21.

[0041] The piston of the second drive cylinder 38 is connected to the first moving component 31, and the piston of the first drive cylinder 37 is connected to the second moving component 32.

[0042] In this embodiment, the lifting mechanism 34 is mounted on the first moving component 31. When the first moving component 31 and the second moving component 32 exchange positions, the first receiving roller 311 can move up and down to prevent it from colliding with the second receiving roller 321.

[0043] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
