Description

Technical Field

[0001] The utility model belongs to the technical field of metal balers, in particular to a locking device for a top pressure plate of a baler. Background Art

[0002] For the top pressure plate mechanism of the metal baler, the flip-type top pressure plate is driven by the top pressure cylinder to extrude the material from above until the top pressure plate is level with the baler chamber. After the top pressure plate is compressed into place by the cylinder, the subsequent side pressure and back pressure will generate a certain reverse force on the metal material and transmit it to the driving cylinder of the top pressure plate, which will cause the cylinder to be overloaded and affect its service life.

[0003] If a telescopic column is set between the top pressure plate and the machine cabin for locking the top pressure plate and the machine cabin, the oil circuit control of the top pressure cylinder can be avoided, that is, all pressure is borne by the telescopic column, which can increase the life of the top pressure cylinder. If a telescopic column is designed, it is necessary to add positioning parts and cylinders and other drives, which will cause a certain amount of pressure on the control system and pump station of the packaging system. At the same time, since the installation position is at the edge of the flip-type top pressure plate, it is not conducive to the installation and layout of the drive and its oil circuit, and is not conducive to the protection of it and the oil circuit, affecting the life. Summary of the Invention

[0004] The purpose of the utility model is to provide a locking device for a top pressure plate of a baling machine. By designing a new locking device, a positioning effect can be achieved through the design of a trapezoidal shell and an extended shell.

[0038] The lifting seat 6 includes a horizontal plate 601, which is horizontally arranged in the extension shell 302. A vertical slide 602 is connected to one side of the horizontal plate 601. The vertical slide 602 slides along the inner side of the front side of the trapezoidal shell 301 through a slide groove 603 and a slide bar 604.

[0039] The telescopic shaft 4 passes through the extension shell 302 and the horizontal plate body 601. The telescopic shaft 4 is fixed to the horizontal plate body 601 and slides with the extension shell 302. A spring 8 is fixed between the horizontal plate body 601 and the top of the extension shell 302. The push plate 401 and the limit plate 402 are fixed to the bottom and top of the telescopic shaft 4 respectively.

[0040] Among them Figure 3 and Figure 5As shown, when the top pressure plate body 2 is horizontally arranged in the baler chamber 1, the top and bottom surfaces of the push plate 401 are respectively in contact with the bottom surface of the extension shell 302 and the top surface of the side wall of the baler chamber 1, the lifting seat 6 is located in the upper position inside the pressure seat body 3, and the vertical slide plate 602 is away from the inner locking port 304.

[0041] Among them Figure 4 As shown, when the top pressure plate body 2 is away from the baler chamber 1, a gap is formed between the push plate 401 and the bottom of the extension shell 302, the lifting seat 6 is located at the lower position inside the pressure seat body 3, the vertical slide plate 602 covers the inner locking port 304, and the end face of the locking shaft 7 is in contact with the inner side surface of the vertical slide plate 602.

[0045] The working principle of the utility model is as follows: the top pressure plate body 2 can be controlled to flip toward the baler chamber 1 by extending the top pressure cylinder of the baler (the piston rod end of the top pressure cylinder is rotatably connected to the top pressure cylinder connecting seat 702 through a hinge seat), thereby pressing the material until the top pressure plate body 2 is in a horizontal state. At this time, the top pressure plate body 2 moves into place. When the top pressure plate body 2 is not in place, the state is as follows Figure 4 As shown, since the end of the locking shaft 7 is blocked by the vertical slide 602, the connecting end 701 is always at the end of the slide rail body 5, so it does not affect the turning drive of the top pressure cylinder and the top pressure pressing. After the top pressure plate body 2 is horizontal, as shown in FIG. Figure 1-3 and Figure 5 As shown, the push plate 401 contacts the top surface of the side wall of the baler chamber 1. The push plate 401 is subjected to resistance and drives the telescopic shaft 4 to slide upward relative to the extension shell 302, thereby driving the lifting seat 6 to move upward. The vertical slide plate 602 moves upward as it slides, thereby disengaging from the inner locking port 304 and the locking shaft 7. The thrust provided by the top pressure cylinder continues to control the end of the locking shaft 7 to pass through the inner locking port 304 and the outer locking port 101, thereby realizing the locking between the top pressure plate body 2 and the baler chamber 1, and the locking shaft 7 will be blocked by the limit piece 501 on the inner side of the slide rail body 5 to play a limiting and positioning role.
