Referring to fig. 1 to 6, a first aspect of an embodiment of the present application provides a platen sealing system, including: the sealing structure comprises a first disc body 1, a sealing structure 2 and a second disc body 3, wherein the peripheral surface of the first disc body 1 is provided with a groove 11, and at least part of the sealing structure 2 is embedded in the groove 11 and used for limiting the sealing structure 2 by the groove 11; the second disc body 3 is detachably connected to the first disc body 1, and a limiting space of the sealing structure 2 is formed between the groove 11 and the second disc body 3; the second disc 3 is abutted against the sealing structure 2. When need dismantle maintenance to seal structure 2, dismantle second disk body 3 from first disk body 1, make one side in spacing space opened, seal structure 2 can deviate from in the spacing space easily, accomplish maintenance or change back to seal structure 2, install seal structure 2 in recess 11 again, connect second disk body 3 to first disk body 1 again, can realize seal structure 2's quick installation, promoted seal structure 2's dismantlement maintenance efficiency.

It should be noted that, referring to fig. 1 and fig. 2, the first disc body 1 and the second disc body 3 are connected to form a main structure of the pressing disc, in a circumferential direction of the pressing disc, an outer peripheral surface of the sealing structure 2 protrudes out of the first disc body 1 and the second disc body 3, and in a material pressing process, the outer peripheral surface of the sealing structure 2 contacts with an inner wall of the charging basket 5 to realize sealing, so that in order to realize limiting of the sealing structure 2, it should be ensured that an outer diameter of the sealing structure 2 is greater than or equal to an outer diameter of the first disc body 1 is greater than or equal to an outer peripheral surface diameter of the second disc body 3 is greater than or equal to an outer peripheral surface diameter of the groove 11. In order to prevent the sealing structure 2 from coming out of the second disc 3 during the pressing, it is preferable that the outer diameter of the first disc 1 is the same as the outer diameter of the second disc 3.

It should be noted that, in the above embodiment, because the sealing structure 2 and the charging basket 5 need to be in interference fit, but the interference between the sealing structure 2 and the inner wall of the charging basket 5 is difficult to control, the interference is too small, so that the sealing is not tight, and the risk of material leakage exists in the pressing process of the pressing disc; the excessive interference can cause quicker abrasion of the sealing structure 2, and the abrasion cannot be compensated, so that the interference can be reduced, and further the sealing is not tight and the materials are leaked; in addition, in order to ensure that the interference between the sealing structure 2 and the charging basket 5 is uniformly distributed along the circumferential direction of the pressing disc, the concentricity requirement on the axis of the pressing disc for installing the sealing structure 2 and the axis of the charging basket 5 is very high, the manufacturing difficulty of the charging basket 5 and the pressing disc body is improved, and the manufacturing cost of the material pressing machine is increased.

In order to realize automatic adjustment and compensation of the interference between the sealing structure 2 and the charging basket 5, in some embodiments of the present application, referring to fig. 1, 3 and 4, the sealing structure 2 includes an inflatable sealing ring 21, the inflatable sealing ring 21 is circumferentially arranged along the first disc 1, after air is inflated into the inflatable sealing ring 21, the inflatable sealing ring 21 is inflated due to elastic deformation, the sealing structure 2 is integrally abutted against the inner wall of the charging basket 5, so as to realize reliable sealing between the pressure plate and the charging basket 5, and because the hollow cavity is arranged inside the inflatable sealing ring 21, gas can flow in the hollow cavity, so that the inflatable sealing ring 21 can adapt to the shape of the inner wall of the charging basket 5 to correspondingly deform, and automatic adjustment of the interference is realized. When the sealing structure 2 is worn due to friction with the charging basket 5, in order to realize the compensation of the interference, the inflation amount of the inflatable sealing ring 21 can be increased, so that the inflatable sealing ring 21 is further inflated, and the gap between the sealing structure 2 and the charging basket 5, which is increased due to the abrasion of the sealing structure 2, is filled.

When the inflatable sealing ring 21 is used for interference adjustment and compensation, a gap exists between the first disc body 1 and the charging basket 5, and an initial interference is not required to be arranged between the sealing structure 2 and the charging basket 5, so that complex theoretical calculation and actual test demonstration are not required for gap control between the sealing structure 2 and the charging basket 5, the working efficiency and the test cost are greatly improved, meanwhile, the pressure plate axle center and the charging basket 5 axle center do not need to have very high concentricity, the equipment processing, manufacturing and mounting difficulties are reduced, the equipment manufacturing and mounting period is shortened, and the equipment cost is reduced.

In the foregoing embodiment, if only the air-filled sealing ring 21 is included in the sealing structure 2, the air-filled sealing ring 21 is more easily deformed than a solid sealing member, and if the external pressure (such as the pressure applied by the material to the air-filled sealing ring 21) is greater than the air pressure inside the air-filled sealing ring 21 during the material pressing, the material is easily leaked.

In order to improve the sealing performance of the sealing structure 2, in some embodiments of the present application, referring to fig. 1, 3 and 4, the sealing structure 2 further includes an annular sealing member 22, the annular sealing member 22 is circumferentially disposed along the first disc 1, and the combination of the annular sealing member 22 and the inflatable sealing ring 21 can improve the overall sealing performance of the sealing structure 2, and when the inflatable sealing ring 21 deforms due to excessive external pressure to cause leakage of materials, reliable sealing can be realized by the annular sealing member 22. As a preferred embodiment of the present application, the annular seal 22 is a solid structure.

It should be noted that, along the axial direction of the platen, the annular seal member 22 may be disposed in the following manner: the single annular sealing piece 22 is arranged on one side of the inflatable sealing ring 21, or two annular sealing pieces 22 are arranged on two sides of the inflatable sealing ring 21, in the two cases, the outer diameter of the inflatable sealing ring 21 in an inflated state is larger than that of the annular sealing piece 22, so that the inflatable sealing ring 21 can be contacted with the inner wall of the charging basket 5 first, and further adjustment and compensation of interference can be realized. Along the circumferential direction of the platen, the annular seal 22 may be provided in the following manner: the annular sealing element 22 is sleeved outside the inflatable sealing ring 21, or the inflatable sealing ring 21 is sleeved outside the annular sealing element 22, and in both cases, the overall outer diameter change of the sealing structure 2 can be realized through inflation and inflation of the inflatable sealing ring 21, so that the adjustment and compensation of the interference magnitude are realized.

In the above embodiment, if the inflatable sealing ring 21 is directly contacted with the inner wall of the charging basket 5, the outer side wall of the inflatable sealing ring 21 is easily worn during repeated friction, so that the inflatable sealing ring 21 leaks gas, and the sealing of the inflatable sealing ring 21 is failed.

In order to avoid the relative friction between the inflatable sealing ring 21 and the charging basket 5, in some embodiments of the present application, referring to fig. 3 and 4, the inner circumferential surface of the annular sealing member 22 is disposed in contact with the outer circumferential surface of the inflatable sealing ring 21, and when the inflatable sealing ring 21 is inflated and deformed, the annular sealing member 22 will expand and deform in the radial direction, so that the outer circumferential surface of the annular sealing member 22 tightly abuts against the inner wall of the charging basket 5 to realize reliable sealing; the inflatable sealing ring 21 is protected inside the annular sealing member 22 through the annular sealing member 22, so that the inflatable sealing ring 21 can be prevented from being damaged due to repeated friction with the charging bucket 5; after the outer annular sealing element 22 is worn due to repeated friction with the inner wall of the charging basket 5, the annular sealing element 22 does not need to be replaced prematurely, the annular sealing element 22 can be extruded to deform outwards along the radial direction to perform gap compensation by increasing the inflation amount of the inflation sealing ring 21, and the overall service life of the sealing structure 2 is prolonged.

It should be noted that, because the inflatable sealing ring 21 and the annular sealing member 22 can both be elastically deformed, when in sealing, the inflatable sealing ring 21 receives the radial pressure applied by the first disc body 1, and the annular sealing member 22 receives the radial pressure applied by the charging basket 5, so that the contact surface of the inflatable sealing ring 21 and the annular sealing member 22 can be tightly attached and sealed, but in order to further improve the sealing performance of the contact surface of the inflatable sealing ring 21 and the annular sealing member 22, the inflatable sealing ring 21 and the annular sealing member 22 can be integrally arranged, or the inflatable sealing ring 21 can be embedded in the inner peripheral surface of the annular sealing member 22, as shown in fig. 4.

In order to facilitate the assembly between the pressing plate and the charging basket 5, a guiding structure is arranged at the bottom end of the annular sealing member 22 outside the sealing structure 2, the bottom end is one end close to the charging basket 5, and the guiding structure can be an inclined surface, an arc surface or a conical surface.

It should be noted that, in order to avoid the displacement of the sealing structure 2 in the limiting space formed by connecting the first disc body 1 and the second disc body 3, the cross-sectional shape of the groove 11 should be kept consistent with the cross-section of the sealing structure 2, so as to achieve close fitting between the sealing structure 2 and the groove 11.

In some embodiments of the present application, referring to fig. 2, the groove 11 includes a first limiting portion 111 and a second limiting portion 112 connected, where the first limiting portion 111 is matched with the inflatable sealing ring 21, and the second limiting portion 112 is matched with the annular sealing member 22, so as to facilitate the fitting of the inflatable sealing ring 21 and the annular sealing member 22 on the first disc 1. The cross-sectional shapes of the inflatable sealing ring 21 and the annular sealing member 22 may be rectangular, circular, etc., and the cross-sectional shapes of the corresponding first limiting portion 111 and the second limiting portion 112 may also be rectangular, circular, etc., so that the sealing structure 2 needs to be removed from the bottom in fig. 2 when the maintenance sealing structure 2 is detached, and the cross-sectional contour line of the first limiting portion 111 is inverted L-shaped.

In order to achieve the inflation deformation of the inflation sealing ring 21, in some embodiments of the present application, referring to fig. 1, the platen sealing system further includes an inflation assembly 4, the inflation assembly 4 includes an air tube 41, a first end of the air tube 41 is connected to the inflation sealing ring 21, a second end of the air tube 41 is connected to an air source, and inflation and deflation of the inflation sealing ring 21 are achieved through the air tube 41, so as to achieve the deformation of the inflation sealing ring 21.

It should be noted that, in the pressing process, the platen can repeatedly move in the charging basket 5, if the position of the air pipe 41 cannot be fixed, the air pipe 41 may enter between the platen and the charging basket 5, and the platen is easy to be blocked.

In order to fix the position of the air tube 41 on the platen, in some embodiments of the present application, referring to fig. 1, the first end of the air tube 41 is embedded in the first disc body 1 and connected to the air tap of the air sealing ring 21, so that the air tube 41 can inflate and deflate the air sealing ring 21 in a fixed position.

It should be noted that, because the air-filled sealing ring 21 is disposed at the edge of the first disc 1, when the air pipe 41 is embedded at the edge of the first disc 1, the connecting pipe 42 at the rear end of the air pipe 41 is still at risk of being blocked between the platen and the charging basket 5.

In order to further avoid the air tube 41 and the connecting tube 42 in the air inflation assembly 4 from being clamped between the pressure plate and the charging basket 5, in some embodiments of the present application, referring to fig. 1 and 2, an accommodating space is provided between the first disc 1 and the second disc 3, the air tube 41 is located in the accommodating space, the first disc 1 is provided with a first through hole 12 and a second through hole 13 which are communicated with the accommodating space, the first end of the air tube 41 is inserted into the first through hole 12, the first through hole 12 is communicated with the groove 11, so as to facilitate the connection between the air tube 41 and the air inflation sealing ring 21, the second end of the air tube 41 is inserted into the second through hole 13, the air tube 41 is hidden inside the pressure plate, the air tube 41 is protected by the accommodating space, and the connecting tube 42 connected with the second end of the air tube 41 is prevented from being clamped by being close to the edge of the pressure plate.

It should be noted that, in the foregoing embodiment, in order to ensure the sealing performance between the pressing plate and the charging basket 5 during the downward pressing process of the pressing machine, more compressed air should be filled into the air-filled sealing ring 21, and when the pressing plate returns, if the air-filled sealing ring 21 is still in the state of swelling deformation, the sealing structure 2 and the charging basket 5 are still in the contact friction state, which results in larger return resistance and larger abrasion loss of the sealing structure 2.

In order to reduce the resistance of the pressure plate during return stroke, in some embodiments of the present application, the inflation assembly 4 further includes a reversing valve, the reversing valve is connected between the air pipe 41 and the air source, the change of the air flow direction in the air pipe 41 is quickly realized through the reversing valve, the inflation and deflation of the inflation sealing ring 21 are quickly realized, the air flow direction can be changed through the reversing valve during return stroke of the pressure plate, the air flow direction in the inflation sealing ring 21 flows to the air pipe, the expansion deformation of the inflation sealing ring 21 is reduced, so that no interference or small interference exists between the sealing structure 2 and the charging bucket 5, the return stroke resistance of the pressure plate is reduced, and the abrasion of the outer peripheral surface of the sealing structure 2 is reduced.

As a preferred embodiment of the application, the reversing valve is an electromagnetic valve, and the electromagnetic valve can be electrically connected with a control system of the material pressing machine to realize automatic control of inflation and deflation.
