[0021] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0022] like Figure 1-Figure 3As shown, the present invention discloses a printing table for a printing press, comprising a frame 1, a lifting structure 2, and a loading platform 3. The frame 1 is formed by connecting a plurality of vertical rods and horizontal rods, and is used to support and fix the lifting structure 2 and the loading platform 3. The frame 1 is a mature product of the prior art and will not be described in detail here.

[0023] The lifting structure 2 includes a motor 21, a worm gear reducer 22, a transmission shaft 23, a first right-angle reducer 24, a first screw 25, a second right-angle reducer 26, a second screw 27 and a lifting plate 28. The motor 21 is fixedly connected to the bottom of the frame 1. The output end of the motor 21 is connected to the middle of the transmission shaft 23 through the worm gear reducer 22. The right end of the transmission shaft 23 is connected to the first screw 25 through the first right-angle reducer 24. The left end of the transmission shaft 23 is connected to the second screw 27 through the second right-angle reducer 26. The first screw 25 and the second screw 27 are both arranged vertically. Please refer to Figure 1 , the first screw rod 25 and the second screw rod 27 both pass through a horizontal bar of the frame 1, and the first screw rod 25 and the second screw rod 27 do not contact the horizontal bar. The first screw rod 25 and the second screw rod 27 can also be connected to the horizontal bar through the bearing seat. In this case, the first screw rod 25 and the second screw rod 27 can be fixedly connected to the rotor of the bearing seat, and the stator of the bearing seat is fixedly connected to the horizontal bar. The first screw rod 25 and the second screw rod 27 are respectively threadedly connected to the two ends of the lifting plate 28. The synchronous rotation of the first screw rod 25 and the second screw rod 27 can drive the lifting plate 28 to move up and down.

[0024] Please refer to Figure 2 The top surface of the lifting plate 28 is provided with a first slot 281, and a first screw hole 282 is provided in the first slot 281. Preferably, the top of the lifting plate 28 is provided with four first slots 281, two of which are provided on one side of the lifting plate 28, and the other two are provided on the other side of the lifting plate 28. In this case, the first slots 281, the first screw rod 25, and the second screw rod 27 are arranged at intervals along the four sides of the lifting plate 28.

[0025] like Figure 2 As shown, the loading platform 3 includes a connecting rod 31 and a platform 32. The top and bottom surfaces of the platform 32 are both provided with second slots 321. The second slots 321 are provided with second screw holes 322. The number of the second slots 321 is the same as that of the first slots 281 and their positions correspond. Figure 3The connecting rod 31 is fixed with a first clamping plate 311 and a second clamping plate 312 at the upper and lower ends, respectively. The first clamping plate 311 and the second clamping plate 312 are each provided with a through hole with a smooth inner wall, and a bolt 4 is inserted into the through hole. During use, the first clamping plate 311 is placed in the second clamping groove 321. At this time, the through hole of the first clamping plate 311 corresponds to the position of the second screw hole 322. The bolt 4 is screwed into the second screw hole 322. The head of the bolt 4 abuts against the first clamping plate 311, thereby fixing the connecting rod 31 to the table 32. The second clamping plate 312 is placed in the first clamping groove 281. At this time, the through hole of the second clamping plate 312 corresponds to the position of the first screw hole 282. The bolt 4 is screwed into the first screw hole 282. The head of the bolt 4 abuts against the second clamping plate 312, thereby completing the fixing of the connecting rod 31 to the lifting plate 28.

[0026] When multiple loading platforms 3 need to be installed, the multiple loading platforms 3 and the connecting rod 31 can be connected in the same manner as the lifting plate 28, the loading platforms 3 and the connecting rod 31, which will not be repeated here.

[0027] During operation, the motor 21 is first started, which drives the transmission shaft 23 to rotate, thereby driving the first and second screws 25, 27 to rotate synchronously. The first and second screws 25, 27 then drive the lifting plate 28 to move up and down, allowing workers to work in a comfortable posture. If additional material partitions are required on the printing table, an appropriate number of loading platforms 3 can be installed on the lifting plate 28, with multiple loading platforms 3 arranged in sequence along the vertical direction.

[0028] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
