[0023] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0024] Referring to Figure 1 The anilox roller transfer device of the present application is arranged beside a printing machine and comprises a conveying trolley 10 and a lifting platform 20 for bearing the conveying trolley 10. A lifting mechanism (not shown in the figure) is arranged below the lifting platform 20, and the lifting platform 20 can be lifted and lowered under the driving of the lifting mechanism. The lifting mechanism can be an electric lifting mechanism, a pneumatic cylinder lifting mechanism or a hydraulic lifting mechanism. In the present embodiment, the lifting mechanism is a hydraulic lifting mechanism.

[0025] As shown in Figure 1 and Figure 3 In the present embodiment, the conveying trolley 10 comprises a bottom plate 101, left and right side plates 102 and 103 fixed to the left and right side edges of the bottom plate 101, and a rear side plate 104 fixed to the rear edge of the bottom plate 101. Four universal wheels 12 are mounted to the bottom surface of the bottom plate 101 at the four corners. A plurality of horizontally forward extending insertion rods 11 are distributed on the front side of the rear side plate 104 for inserting the anilox rollers. A push handle 105 is arranged on the rear side of the rear side plate. A plurality of insertion rods are distributed on the conveying trolley, so that a plurality of anilox rollers can be inserted at the same time, and the anilox rollers can be quickly transferred at one time, thereby saving a large amount of manual carrying time. In addition, a bumper pad 13 is sleeved at the root of the insertion rod 11 of the conveying trolley. The bumper pad can absorb and disperse the impact force, thereby protecting the anilox rollers.

[0026] In the present embodiment, a moving platform 30 capable of sliding towards the printing machine is arranged on the lifting platform 20. The moving platform is connected to the lifting platform by sliding, thereby expanding the operation range, facilitating the operation of workers and improving the efficiency of replacing the anilox rollers.

[0027] In the present embodiment, an avoiding opening 301 is arranged at the rear end of the moving platform 30. The avoiding opening 301 is arranged to prevent the conveying trolley from being interfered by the moving platform when the conveying trolley is pushed onto the lifting platform.

[0028] As shown in Figure 3As shown, in this embodiment, linear guide rails 31 are installed on both sides of the bottom surface of the mobile platform 30. Several sliders 32 are installed on the top surface of the lifting platform 20 corresponding to the positions of the linear guide rails 31. The linear guide rails 31 and the sliders 32 are slidably connected. Multiple sliders 32 on the same side are fixed to the lifting platform 20 by mounting plates 33.

[0029] like Figure 1 and Figure 2 As shown, in this embodiment, a first positioning structure for positioning the moving platform 30 is provided on the lifting platform 20. This first positioning structure includes a first pin 41 fixed to the rear end face of the moving platform 30, and a first positioning hole 40 on the surface of the lifting platform 20 that engages with the first pin 41. Here, multiple first positioning holes 40 can be provided along the forward movement direction of the moving platform. When the moving platform needs to slide forward to different positions, simply inserting the first pin into the corresponding first positioning hole allows for quick and stable positioning of the moving platform, greatly improving the flexibility and efficiency of the moving platform's position adjustment.

[0030] In this embodiment, first guardrails 34 are installed on the front, left, and right edges of the mobile platform 30, respectively. Second guardrails 201 are installed on both the left and right edges of the lifting platform 20. Specifically, the left first guardrail 34 is located inside the left second guardrail 201, and the right first guardrail 34 is located inside the right second guardrail 201. This structure ensures that the mobile platform 30 is not interfered with when moving towards the lifting platform 20. Furthermore, the distance between the left and right first guardrails 34 is greater than the overall width of the conveyor trolley, thereby ensuring smooth passage of the conveyor trolley in and out of the lifting platform 20 without interference.

[0031] In this embodiment, the lifting platform 20 has a second positioning structure for positioning the conveying trolley. This second positioning structure includes a second pin 43 fixed to the front end face of the conveying trolley 10. The lifting platform 20 has a second positioning hole 42 that mates with the second pin 43. When the conveying trolley moves forward to the second positioning hole, simply inserting the second pin into the second positioning hole securely positions the conveying trolley. Multiple second positioning holes can be provided along the forward movement direction of the conveying trolley. This allows the worker to more easily retrieve or insert the anilox roller from the conveying trolley when changing the anilox roller on the printing press while standing on the moving platform 30, by moving the conveying trolley forward.

[0032] like Figure 3 As shown, in this embodiment, a third pin 44 is installed on the rear end face of the conveying trolley 10. The lifting platform has a guide groove 45 that cooperates with the third pin 44 to provide guidance and positioning.

[0033] When the printing machine's screen roller needs to be replaced, the new screen roller is first inserted into the conveying trolley 10. Then, the conveying trolley 10 loaded with the screen roller is pushed onto the lifting platform 20, and the conveying trolley 10 is positioned by the second pin 43 and the second positioning hole 42, ensuring that the conveying trolley 10 is stable in position. The lifting mechanism is started, and the lifting platform 20 is lifted to an appropriate height, so as to facilitate the replacement of the screen roller on the printing machine. Then, according to the need, the moving platform 30 is pushed to slide towards the printing machine, expanding the operation range, and at the same time, the moving platform 30 is positioned by the first pin 41 and the first positioning hole 40, ensuring that the moving platform is stable in position. Then, the worker stands on the moving platform, takes the screen roller from the conveying trolley 10, and inserts it into the printing machine or performs the reverse operation, i.e., removes the old screen roller and puts it back into the conveying trolley. After replacing the screen roller, the moving platform is moved to the initial position, the lifting mechanism is started, and the lifting platform 20 is lowered to the ground, and the conveying trolley 10 is moved to the designated position.

[0034] The above describes one embodiment of the present application in detail, but the content described is only a preferred embodiment of the present application, and cannot be considered as limiting the scope of the present application. Any equivalent changes and improvements made within the scope of the present application should still belong to the patent coverage of the present application.
