[0026] Example 2

[0027] Reference Figures 1-6 In the case that other parts are same with example 1, the difference between the utility model and example 1 is that:

[0028] The inside of protection box 3 is equipped with several guide plates 11, the guide plates 11 are evenly spaced and sleeved on the outside of hydraulic cylinder, the end portions of the guide plates 11 are all provided with flow-through openings, the flow-through openings are staggered, one end of air inlet pipe 9 extending to the inner bottom surface of protection box 3 is located inside protection box 3, the end portion of the other end of air inlet pipe 9 located outside protection box 3 is provided with a dust plug, a plurality of through holes are arranged on the plate body of linkage plate 5 and are arranged along the axis of the gas outlet and the circumferences of the circles, a guide rod 12 is arranged in each through hole, the upper end of guide rod 12 is fixedly connected with control piece 6, the arrangement of guide plate 11 makes the gas entering protection box 3 from air inlet pipe 9 unable to flow directly upward and need to be reversed and folded several times along guide plate 11 before entering exhaust cylinder 4, that is, under the action of guide plate 11, the fresh gas can fully contact with the hydraulic cylinder, that is, the heat dissipation effect of the hydraulic cylinder is effectively improved, the arrangement of dust plug facilitates reducing dust and other impurities entering protection box 3 from air inlet pipe 9, and the arrangement of guide rod 12 can limit the movement of control piece 6, that is, the phenomenon that control piece 6 is skewed and cannot completely cover the gas outlet is avoided, which avoids the phenomenon that control piece 6 is too heavy to be blown up by the gas due to the hollow state inside.

[0029] The lower end of the guide rod 12 is provided with a limiting protrusion, the inside of the guide rod 12 is in a hollow state, the middle barrel of the exhaust cylinder 4 has a thickness of 1.5MM and a smooth surface, the inside of the exhaust cylinder 4 is provided with a dust screen at the upper end, and a circular table-shaped flow cover is jointly arranged between the lower end of the exhaust cylinder 4 and the upper end of the protection box 3, the protection box 3 and the bottom plate 2 are connected through screws, the protection box 3 and the flow cover are connected through screws, the setting of the limiting protrusion avoids the phenomenon that the guide rod 12 directly separates from the linkage plate 5, the setting of the dust screen is convenient for avoiding dust falling from the outside to the control piece 6, and since the exhaust cylinder 4 and the protection box 3 can be conveniently disassembled through screws, when the hydraulic cylinder accidentally bursts, personnel can conveniently collect the liquid accumulated at the bottom of the protection box 3 after disassembling the flow cover, so as to avoid the adverse effects of liquid leakage on the paper disc machine body 1 during subsequent maintenance.

[0030] Principle and advantages: in the use process, the hydraulic cylinder arranged on the bottom plate 2 cooperates with the paper disc machine body 1 to complete the processing and production of the paper disc, and then when the hydraulic cylinder accidentally bursts, the splashing liquid directly impacts the inner wall of the protection box 3, at this time, the protection box 3 blocks the liquid, thereby avoiding the phenomenon that the liquid directly splashes to the ground, equipment or personnel outside, that is, avoiding the harm to the external environment, equipment or personnel; meanwhile, through the mutual cooperation of various parts, the linkage frame 7 is driven to rotate synchronously when the hydraulic cylinder works, and the linkage plate 5 is driven to move synchronously up and down through the inner wall of the exhaust cylinder 4 under the action of the two magnetic attraction pieces 8 when the linkage frame 7 moves up and down, and then under the action of the control piece 6, when the linkage plate 5 moves up, the control piece 6 is tightly attached to the upper surface of the linkage plate 5, that is, the exhaust cylinder 4 generates suction force to suck the gas in the protection box 3 into the inside of the exhaust cylinder 4, and then the fresh air outside enters into the inside of the protection box 3 through the air inlet pipe 9 and the one-way valve 10, and when the linkage plate 5 moves down, the gas in the protection box 3 cannot go out due to the blocking of the one-way valve 10, so that the gas pressure in the protection box 3 and the exhaust cylinder 4 increases, and then the gas pushes the control piece 6 to move up, so that the gas outlet is exposed, that is, the gas in the exhaust cylinder 4 flows out along the gas outlet, so that during the up and down movement of the linkage plate 5, the gas in the protection box 3 and the fresh air outside are circulated and flowed, that is, the hydraulic cylinder is effectively cooled.

[0031] Further need to be further explained is that the setting of the guide plate 11 makes the gas entering into the inside of the protection box 3 through the air inlet pipe 9 unable to flow directly upward when flowing upward, and the fresh gas can enter into the inside of the exhaust cylinder 4 only after being reversed and turned over along the guide plate 11 for multiple times, that is, under the action of the guide plate 11, the fresh gas can fully contact with the hydraulic cylinder, that is, the heat dissipation effect on the hydraulic cylinder is effectively improved, the setting of the dust plug facilitates to reduce the dust and sundries entering into the inside of the protection box 3 through the air inlet pipe 9, the setting of the guide rod 12 can limit the movement of the control piece 6, that is, the phenomenon that the control piece 6 is skewed and cannot completely cover the air outlet is avoided, which avoids the hollow inside, thereby avoiding the phenomenon that the control piece 6 is too heavy to be blown up by the gas; and since the exhaust cylinder 4 and the protection box 3 can be conveniently disassembled through the screw, when the cylinder explodes accidentally, personnel can conveniently collect the liquid accumulated at the bottom of the protection box 3 after disassembling the baffle, so as to avoid that the liquid leakage causes adverse effects on the paper tray machine main body 1 during subsequent maintenance.

[0032] The above is only a preferred specific implementation manner of the present application, but the protection scope of the present application is not limited to this, any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
