DETAILED DESCRIPTION

[0023] Various exemplary embodiments, features and aspects of the present application will be described in detail below with reference to the accompanying drawings. The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise specified.

[0024] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0025] In addition, in order to better illustrate the present application, numerous specific details are provided in the specific embodiments below. It should be understood by those skilled in the art that the present application can also be implemented without certain specific details. In some examples, methods, means, and elements well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present application.

[0026] See also Figure 1-Figure 7In an embodiment of the utility model, a mobile lifting platform for automatically loading and unloading material rolls includes: a frame 1, which is a coating machine, a printing machine or other processing machinery involving large-scale core rolls; a side support member connected to a lifting drive mechanism installed on the frame 1, a support platform is slidably installed on the side support member, and the support platform is connected to a horizontal driving member installed on the side support member; a receiving platform 2, the receiving platform 2 is rotatably installed on the support platform and is connected to an adjusting member installed on the support platform for changing the placement angle of the receiving platform 2 relative to the support platform.

[0027] When the material roll is disassembled, the lifting drive mechanism drives the receiving platform 2 to move up and fine-tunes the horizontal position of the receiving platform 2 through the horizontal drive member, so that the receiving platform 2 abuts against the material roll, and then the material roll is separated from the plug (a rotating connector for connecting with the material roll), and then the lifting drive mechanism drives the receiving platform 2 and the material roll placed on the receiving platform 2 to move down, and then the receiving platform 2 is rotated a certain angle through the adjustment member to realize the movement of the material roll out of the receiving platform; when installing the material roll, keep the receiving platform 2 in a horizontal position, place the material roll to be installed on the receiving platform 2, and then set the lifting drive mechanism. The mechanism drives the receiving platform 2 to move upward, and drives the horizontal position of the receiving platform 2 through the horizontal driving member, so that the axial direction of the material roll is in line with the axial direction of the plug, thereby realizing the positioning and installation; the above-mentioned lifting driving mechanism and horizontal driving member are controlled by the PLC control system, and the PLC control system establishes communication with the ultrasonic detection unit, ultrasonically detects the size of the material roll, and then feeds back the data to the PLC control system. The PLC control system controls the lifting driving mechanism and the horizontal driving member to adjust the receiving platform 2 to move a corresponding distance to reach the plug position, so as to realize the precise positioning, docking and detachment of the material roll.

[0028] In this embodiment, the three-dimensional movement of the receiving platform 2 is realized by the setting of the lifting drive mechanism and the horizontal drive member, so as to realize the precise positioning of the material roll during loading and unloading, facilitate the docking and detachment of the material roll, and no other auxiliary tools are required. It is highly safe and effectively improves the loading and unloading efficiency.

[0029] For further information, see Figure 1 , Figure 3 and Figure 4 The support platform includes two symmetrically arranged mounting frames 3, and the two mounting frames 3 are fixed by a second support frame 20; the receiving platform 2 is placed between the two mounting frames 3 and is rotatably connected to the two mounting frames 3 through a rotating shaft, and the adjusting member includes a cylinder 17, which is rotatably mounted on the mounting frames 3, and the movable end of the cylinder 17 is hinged to the receiving platform 2.

[0030] The cylinder 17 may also be replaced by an electric telescopic rod or a hydraulic rod, as long as the telescopic drive requirements are met, and this embodiment does not make any specific limitation to this.

[0031] After the receiving platform 2 is installed between the two mounting frames 3, effective support of the receiving platform 2 is achieved, and when the receiving platform 2 is in a horizontal placement state, the upper surface of the receiving platform 2 and the upper surface of the mounting frame 3 are in the same horizontal placement state, and the arranged cylinder 17 can drive the receiving platform 2 to rotate relative to the mounting frame 3 during telescopic movement, so that when the material roll is disassembled, the material roll can automatically roll out under the action of gravity, and no manual or other auxiliary machinery is required to assist in unloading. On the one hand, this improves the safety of loading and unloading, and on the other hand, it can effectively reduce manpower output.

[0032] Preferably, in order to effectively prevent the material roll from rolling randomly on the receiving platform 2, a plurality of rollers 201 are rotatably installed on the receiving platform 2, and the rollers 201 protrude from the upper surface of the receiving platform 2. When the material roll is placed on the receiving platform 2, the material roll can be placed between two rollers 201 to limit the position of the material roll and improve the safety of loading and unloading the material roll.

[0033] Preferably, at least two support columns 21 are fixed to the opposite surfaces of the two mounting frames 3. When the receiving platform 2 abuts against the support columns 21, the receiving platform 2 is in a horizontal position. The provided support columns 21 can effectively support the receiving platform 2, reduce the pressure of the receiving platform 2 on the cylinder 17, and thus play a certain protective role on the cylinder 17.

[0034] For further information, see Figure 4-Figure 7 The side support member includes two symmetrically arranged side panels 10, and a first support frame 16 is fixed between the two side panels 10; at least one second slide rail 14 is formed on the side of the side panel 10 facing the mounting frame 3, and a second slider 13 fixed on the mounting frame 3 is slidably connected to the second slide rail 14.

[0035] The horizontal driving member described above includes a second screw rod 15 which is parallel to the second slide rail 14 and rotationally connected to the side plate 10, the second screw rod 15 passes through the mounting frame 3 and is threadedly connected to the mounting frame 3; a second motor 9 is installed on the side plate 10, and the output shaft of the second motor 9 is rotationally connected to the second screw rod 15 through a gear set 19.

[0036] When the second motor 9 is working, the gear set 19 drives the second screw rod 15 to rotate. When the second screw rod 15 rotates, it cooperates with the limiting effect of the second slide rail 14 to realize the driving effect on the mounting frame 3, so that the mounting frame 3 and the receiving platform 2 installed on the mounting frame 3 are moved horizontally to change the position of the material roll placed on the receiving platform 2, thereby accurately positioning the material roll and the plug for convenient loading and unloading.

[0037] It should be noted that a second motor 9 is installed on each of the two side panels 10, and the output shafts of the two second motors 9 are connected through a transmission shaft 18. The output power of the two second motors 9 is the same, thereby realizing synchronous and unidirectional driving of the two mounting frames 3 and increasing the stability of the movement of the mounting frames 3.

[0038] For further information, see Figure 1-Figure 3 and Figure 5 At least one first slider 11 is fixed on the side of the side plate 10 away from the mounting frame 3, and the first slider 11 is slidably connected to the first slide rail 12 fixed on the frame 1. The lifting drive mechanism includes: a first screw rod 4 symmetrically rotated on the frame 1, and the two first screw rods 4 are driven to rotate by a driving source installed on the frame 1; a threaded sleeve 6 is threadedly connected to the first screw rod 4, and the threaded sleeve 6 is fixedly connected to the connecting frame 5 installed on the side plate 10.

[0039] Among them, it should be supplemented that the first screw rod 4 is a ball screw, and two first screw rods 4 are provided and are respectively located on both sides of the frame 1. The two first screw rods 4 are connected to a driving source, so as to realize the synchronous driving and lifting of the two side panels 10, thereby improving the lifting and lowering stability of the two side panels 10. The driving source described here includes a first motor 7 installed on the frame 1, and the output shaft of the first motor 7 is respectively connected to the two first screw rods 4 through two transmission members 8.

[0040] When the first screw rod 4 rotates, the threaded sleeve 6 drives the connecting frame 5 and the entire body mounted on the connecting frame 5 to move vertically, thereby driving the material roll placed on the receiving platform 2 to move up and down to meet the lifting requirements.
