[0013] Figure 1 is a structural schematic diagram of the present utility model;

[0014] Figure 2 is Figure 1 a partial enlarged view of part A in DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] The following combines Figures 1 to 2 and further illustrates the technical solutions of the present utility model through specific embodiments.

[0016] As Figure 1 shown, the connecting and adjusting device for the printing machine platen includes: a platen 1, a connecting plate 5, a connecting rod 12, a frustum 10, a spring 9, and a pressing rod 6. A bracket 2 is provided at the bottom of the platen 1, and the connecting plate 5 is horizontally arranged at the bottom of the bracket 2. In this embodiment, a second screw 4 vertically penetrating the bracket 2 and extending below the connecting plate 5 is provided in the platen 1, and a second nut 3 located below the connecting plate 5 is provided on the second screw 4 to realize the fixation of the platen 1 and the connecting plate 5, with a stable structure. The bracket 2 can be made of a hollow square tube, with light self-weight and good support performance.

[0017] The connecting rod 12 is arranged on the connecting plate 5 below two adjacent platens 1 to perform the movable connection of the connecting plates 5 below two adjacent platens 1. The frustum 10 is vertically arranged at both ends of the top of the connecting plate 5 and penetrates upward through the ends of the corresponding connecting rods 12. As Figure 2 shown, a tapered hole 18 corresponding to the frustum 10 is provided at the end of the connecting rod 12. Through the cooperation of the tapered hole 18 and the frustum 10, self-centering is performed, and the adaptability of the connecting rod 12 to the gap change between two adjacent platens 1 is improved.

[0018] A guide wheel fixing seat 13 is provided at the bottom of the connecting plate 5 and is located below the frustum 10. Guide wheels 14 are symmetrically provided at the bottom of the guide wheel fixing seat 13. The guide wheels 14 are located on both sides of the elliptical printing machine along the elliptical track to guide the movement of the connecting plate 5.

[0019] As Figure 2 shown, a first positioning cylinder 16 extending into the connecting plate 5 is provided at the bottom of the frustum 10. A first positioning blind hole 17 corresponding to the first positioning cylinder 16 is concavely provided on the top surface of the connecting plate 5, which is convenient for assembly. The pressure rod 6 horizontally penetrates through the bracket 2 and extends above the frustum 10. A second positioning cylinder 11 penetrating through the pressure rod 6 and extending into the platen 1 is provided at the top of the frustum 10. A second positioning blind hole 19 corresponding to the second positioning cylinder 11 is concavely provided on the bottom surface of the platen 1. The first positioning cylinder 16, the frustum 10, and the second positioning cylinder 11 are made of an integrated steel structure with high strength.

[0020] The frustum 10 is pressed and positioned between the platen 1 and the connecting plate 5 through the first positioning cylinder 16 and the second positioning cylinder 11, with high stability. There is no need to additionally use screws to fix the frustum 10, and the tensile effect is good.

[0021] The spring 9 is arranged on the frustum 10 and is located between the pressure rod 6 and the connecting rod 12. Through the pre-compression of the spring 9, effective elastic limit of the connecting rod by the spring 9 is achieved. Moreover, the pressure rod 6 can further improve the tensile effect of the frustum 10, killing two birds with one stone and improving the structural reliability.

[0022] A chute 15 corresponding to the pressure rod 6 is vertically provided in the bracket 2 to adapt to the lifting adjustment of the pressure rod 6 and guide the lifting of the pressure rod 6 to avoid deflection. A first screw 7 extending downward below the connecting plate 5 is provided on the pressure rod 6. A first nut 8 is provided on the first screw 7 and is located below the connecting plate 5. The lifting of the pressure rod 6 is adjusted by rotating the first nut 8, changing the pre-compression of the spring 9, and achieving effective elastic limit of the connecting rod 12 by the spring 9, which is convenient for adjustment.
