Description

Technical Field

[0001] The utility model relates to the technical field of pressing material sealing, in particular to a pressing material automatic exhaust structure and a pressing machine. Background Art

[0002] At present, the exhaust method on the pressing plate of the pressing machine mainly relies on a self-made dumbbell-shaped valve core for exhaust. The exhaust principle is to use the deadweight of the dumbbell-shaped valve core to fall, so that the cavity formed between the pressing plate and the material in the barrel is connected with the air hole on the pressing plate to achieve exhaust. As the pressing plate continues to descend, the air in the barrel is gradually emptied, so that the material surface in the barrel contacts the bottom surface of the dumbbell-shaped valve core, and then the valve core is lifted up, so that the valve core can close the air hole, thereby achieving a sealing effect. However, due to different formulas of the pressed materials, the density of the materials will also be different, and the weight of the valve core cannot be adjusted, which may make the material unable to push the valve core up, so that the valve core cannot block the air hole on the pressing plate, causing the material to leak from the air hole and fail to achieve a sealing effect.

[0048] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0049] It should be noted that if a directional indication is involved in the embodiments of the present invention, the directional indication is only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0050] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0051] At present, the exhaust method on the pressing plate of the pressing machine mainly relies on a self-made dumbbell-shaped valve core for exhaust. The exhaust principle is to use the deadweight of the dumbbell-shaped valve core to fall, so that the cavity formed between the pressing plate and the material in the barrel is connected with the air hole on the pressing plate to achieve exhaust. As the pressing plate continues to descend, the air in the barrel is gradually emptied, so that the material surface in the barrel contacts the bottom surface of the dumbbell-shaped valve core, and then the valve core is lifted up, so that the valve core can close the air hole, thereby achieving a sealing effect. However, due to different formulas of the pressed materials, the density of the materials will also be different, and the weight of the valve core cannot be adjusted, which may make the material unable to push the valve core up, so that the valve core cannot block the air hole on the pressing plate, causing the material to leak from the air hole and fail to achieve a sealing effect.

[0052] Based on this, the utility model provides an automatic exhaust structure for pressing materials, which is used in a pressing machine, and aims to solve the problem that the valve core of the existing pressing plate sealing structure cannot seal the pressing plate. Figures 1 to 4 The structural entity of the automatic exhaust structure of the material pressing provided for the Bengbu South Utility Model; Figure 5 to Figure 6 It is a structural schematic diagram of the material pressing machine of the utility model.

[0053] See also Figures 1 to 4 The press automatic exhaust structure 100 includes a mounting seat 110, a movable part 120 and a balancing part 130. The mounting seat 110 is formed with a ventilation channel 111. The mounting seat 110 is used to be installed on the press plate 300 of the press machine 1000. The movable part 120 is movably installed at the lower end of the mounting seat 110 in the up and down directions. Within its movable stroke, the movable part 120 can open or close the ventilation channel 111. The balancing part 130 is arranged between the mounting seat 110 and the movable part 120 to balance the weight of the movable part 120.

[0054] In the technical solution of the utility model, the mounting seat 110 is formed with a ventilation channel 111 to allow the air between the pressing plate 300 and the barrel 700 to be discharged, and the movable member 120 is movably installed at the lower end of the mounting seat 110 in the up-down direction, so that when the pressing machine 1000 needs to be vented, the ventilation channel 111 is opened, and when it is not needed to be vented, the ventilation channel 111 is closed, so that the pressing plate 300 can pressurize the material 800 in the barrel 700, and the balancing member 130 is arranged between the mounting seat 110 and the movable member 120 to balance the weight of the movable member 120, so that the movable member 120 can rise when subjected to a smaller driving force, so that the movable member 120 can close the ventilation channel 111, so that the pressing plate 300 can be pressurized by the material 800 in the barrel 700, and the balancing member 130 can be balancing the weight of the movable member 120, so that the movable member 120 can rise when subjected to a smaller driving force, so that the movable member 120 can close the ventilation channel 111, so that the pressing plate 300 can be pressurized by the movement of the movable member 120. The automatic exhaust structure 100 can exhaust the air between the pressing plate 300 and the barrel 700 so that the pressing plate 300 can be close to the surface of the material 800 in the barrel 700, and can also close the ventilation channel 111, so that the pressing plate 300 can apply pressure to the material 800 in the barrel to press the material 800 out of the barrel 700. At the same time, the balancing member 130 is provided to reduce the driving force for driving the movable member 120 to move, so that the movable member 120 can be moved by a smaller driving force, so as to avoid being unable to drive the movable member 120 to move due to the small density of the material 800, so that the movable member 120 can adapt to materials 800 of different densities, which can effectively reduce the risk of leakage of the material 800, thereby solving the problem that the valve core of the sealing structure of the existing pressing plate 300 cannot seal the pressing plate 300.

[0055] Furthermore, the balancing member 130 includes a balancing spring. Thus, by providing the balancing spring to pull the movable member 120, the driving force driving the movable member 120 to move is reduced, so that the material 800 with a smaller density can also drive the movable member 120 to move upward, so as to close the ventilation channel 111. Of course, in other embodiments, the balancing member 130 may also be rubber, etc., and the present invention does not limit this.

[0056] In some embodiments of the present invention, since the material 800 usually has a relatively large viscosity, after the material pressing disk 300 presses the material, the lower end of the movable part 120 is easily adhered to the material pressing disk 300, so that the movable part 120 cannot fall under the action of its own gravity, resulting in the inability of the automatic exhaust structure 100 for pressing the material to be exhausted. For this reason, in the present embodiment, the automatic exhaust structure 100 for pressing the material also includes a first linear driving structure 140 arranged on the mounting seat 110, the first linear driving structure 140 has a relative fixed end and a driving end, the driving end has an active stroke in the up and down direction, the fixed end is arranged on the mounting seat 110, and the driving end drives the movable part 120. In this way, by setting the first linear driving structure 140, after the material pressing disk 300 presses the material, the movable part 120 is forced to move downward so that the movable part 120 opens the ventilation channel 111, so as to avoid the problem that the automatic exhaust structure 100 for pressing the material cannot be exhausted due to the adhesion of the movable part 120 to the material pressing disk 300. It is understandable that the first linear drive structure 140 may be a driving cylinder or a driving oil cylinder, etc., and the present invention does not limit this.

[0057] In some embodiments of the utility model, the mounting seat 110 includes a seat body and a cover plate detachably mounted on the seat body, the upper end of the seat body is open, the cover plate is covered on the opening of the seat body to form a mounting cavity with the seat body, the cover plate is provided with an exhaust hole connected to the mounting cavity, and the lower end of the mounting seat 110 is provided with an air vent connected to the mounting cavity, wherein the air passage 111 includes the exhaust hole, the mounting cavity and the air vent, so that the automatic exhaust structure 100 for pressing materials can discharge the air between the pressing plate 300 and the material barrel 700.

[0058] In some embodiments of the present invention, please refer to Figures 2 to 4The material pressing automatic exhaust structure 100 also includes a transmission structure 150, and the transmission structure 150 includes a transmission frame 151 and a transmission sleeve 152. The upper end of the transmission frame 151 is arranged at the driving end, and the upper end of the transmission sleeve 152 is arranged at the lower end of the transmission frame 151, and the lower end is arranged at the movable part 120. In this way, the driving force of the first linear driving structure 140 is transmitted to the movable part 120 through the transmission frame 151 and the transmission sleeve 152, so that the first linear driving structure 140 can drive the movable part 120 to move in the up and down directions.

[0059] It should be noted that there are many ways to connect the transmission frame 151 and the driving end. The transmission frame 151 can be fixed to the driving end by screws or by welding, etc., and the present invention does not limit this. Similarly, the transmission sleeve 152 can be installed on the movable part 120 by a threaded connection structure or by riveting, etc., and the present invention does not limit this.

[0060] In some embodiments of the present invention, the movable part 120 includes a movable body 121 and a sealing disk 122. The movable body 121 extends in the up and down directions. The upper end of the movable body 121 is drivingly connected to the driving end. The sealing disk 122 is arranged at the lower end of the movable body 121 to open or close the ventilation channel 111. In this way, the movable body 121 is arranged so as to be drivingly connected to the driving end, and the sealing disk 122 is arranged so that the movable part 120 can open or close the ventilation channel 111.

[0061] In some embodiments of the utility model, the outer wall of the movable body 121 is provided with a first mounting groove, and the material pressing automatic exhaust structure 100 also includes a first limiting portion 160 provided in the first mounting groove, for limiting the downward movement of the movable body 121.

[0062] In some embodiments of the utility model, a receiving groove 112 is provided at the lower end of the mounting seat 110 for accommodating the movable part 120. Thus, by providing the receiving groove 112, when the movable part 120 closes the ventilation channel 111, the lower end surface of the movable part 120 is flush with the lower end surface of the pressing plate 300, so as to prevent the movable part 120 from protruding from the pressing plate 300. This can prevent the automatic exhaust structure 100 from being damaged due to the high pressure, and can also prevent the material 800 from remaining due to the gap formed between the pressing plate 300 and the barrel 700.

[0063] In some embodiments of the present invention, the movable part 120 is provided with a second mounting groove, and the press material automatic exhaust structure 100 further includes a first sealing member 170 provided in the second mounting groove to close the gap between the mounting seat 110 and the movable part 120. Thus, by providing the second mounting groove, the position of the first sealing member 170 is located on the movable part 120, so that the first sealing member 170 can be installed on the movable part 120, and by providing the first sealing member 170, when the movable part 120 is pressed against the mounting seat 110, the gap between the mounting seat 110 and the movable part 120 is sealed, thereby helping to improve the sealing effect of the press material automatic exhaust structure 100. It can be understood that the first sealing member 170 can be an O-ring, or a sealing pad, etc., and the present invention does not limit this.

[0064] In some embodiments of the present invention, a second seal 180 is provided on the outer wall of the mounting seat 110 for closing the gap between the mounting seat 110 and the pressing plate 300. Thus, by providing the second seal 180, the gap between the mounting seat 110 and the pressing plate 300 is sealed to prevent gas from flowing out of the gap between the mounting seat 110 and the pressing plate 300, thereby helping to improve the sealing effect of the automatic exhaust structure 100 for pressing.

[0065] In addition, the utility model also provides a material pressing machine 1000, please refer to Figure 1 and Figure 5The material pressing machine 1000 includes a door frame 200, and the material pressing plate 300 is movably installed on the door frame 200 along the up-down direction to press the material 800 in the barrel 700 out of the barrel 700. The material pressing automatic exhaust structure 100 is arranged on the material pressing plate 300. The material pressing sealing structure includes the above-mentioned material pressing automatic exhaust structure 100 to exhaust the gas in the barrel 700 so that the material pressing plate 300 can be close to the material 800. The driving device 400 is driven and connected to the material pressing plate 300 to drive the material pressing plate 300 to move along the up-down direction. In this way, through The door frame 200 is provided to install the driving device 400 and the pressing plate 300. The pressing plate 300 is provided to press the material 800 in the barrel 700 out of the barrel 700.

It can be understood that there are many types of driving devices 400, and the driving device 400 can be a linear driving structure, a crank slider structure, etc., and the utility model does not limit this.

[0066] It should be noted that the structure of the press sealing mechanism 100 in the press machine 1000 can refer to the embodiment of the press sealing mechanism 100 mentioned above, which will not be described in detail here; since the press sealing mechanism 100 mentioned above is used in the press machine 1000 provided in the utility model, the embodiment of the press machine 1000 provided in the utility model includes all the technical solutions of all the embodiments of the press sealing mechanism 100 mentioned above, and the technical effects achieved are also exactly the same, which will not be described in detail here.

The positioning structure 600 is arranged between the door frame 200 and the lifting frame 500 to position the lifting frame 500 at the pressing position. When feeding materials, the lifting frame 500 first moves downward to the feeding position so as to move the material barrel 700 onto the lifting frame 500, and then the lifting frame 500 moves upward to the pressing position, and the positioning structure 600 then fixes the lifting frame 500 at the pressing position so as to facilitate the subsequent pressing of the material by the pressing plate 300. In this way, by setting the positioning structure 600, the lifting frame 500 can be fixed at the pressing position, which facilitates the pressing of the material by the pressing plate 300. At the same time, by setting the lifting frame 500, the material barrel 700 can be lifted to the pressing position so that the roller of the material barrel 700 is suspended, which can not only avoid the roller of the material barrel 700 from bearing pressure, but also facilitate the connection of the material barrel 700 with the subsequent device.

Furthermore, the lifting frame 500 is also provided with an in-position switch to determine whether the material barrel 700 is in position; and / or,

[0071] In some embodiments of the utility model, the lifting frame 500 is provided with a guide structure, and the guide structure includes two guide columns 530 arranged at intervals in the horizontal direction to guide the bucket 700 to move into the lifting frame 500.

In this way, by setting the second limiting portion 210, after the pressing plate 300 completes the pressing of the material, the upward movement of the barrel 700 is limited to prevent the barrel 700 from moving upward driven by the pressing plate 300, so that the pressing plate 300 can be separated from the barrel 700.

[0074] In some embodiments of the present invention, the lifting frame 500 is provided with a third limiting portion 540 abutting against the pressing plate 300, so that the lifting frame 500 can move under the drive of the pressing plate 300. In this way, by setting the third limiting portion 540 so as to abut against the pressing plate 300, the barrel can move upward under the drive of the pressing plate 300, so that the elevator can be driven by the first linear drive structure 140, so as to avoid the need to additionally set up a driving device 400 to drive the lifting frame 500, thereby helping to simplify the structure of the pressing machine 1000.

[0075] The pressing process of the pressing machine 1000 will be described below in combination with the above embodiments:

[0076] The operator moves the material barrel 700 and guides the material barrel 700 to abut against the positioning baffle 520 through the guidance of the guide structure. When the material barrel 700 is confirmed to be in place, the driving device 400 drives the pressing plate 300 to rise, driving the lifting frame 500 to rise synchronously to lift the material barrel 700 so that the casters of the material barrel 700 are suspended in the air. When the lifting frame 500 moves to the pressing position, the driving device 400 stops moving, so that the pressing plate 300 and the lifting frame 500 stop rising. Subsequently, the operator inserts the plug plate into the positioning hole on the door frame 200 to position the lifting frame 500 in the pressing position, and then the driving device 400 drives the pressing plate 300 to descend, so that the pressing plate 300 and the lifting frame 500 are in contact with each other. The lowering frame 500 is separated, and the pressing plate 300 continues to descend, so that the distance between the pressing plate 300 and the surface of the material 800 in the barrel 700 becomes smaller and smaller, so as to discharge the vent 111 of the pressing plate 300 and the automatic exhaust structure 100 of the pressing material of the barrel. As the pressing plate 300 continues to be pressed downward, the movable part 120 moves upward under the drive of the viscous material 800 in the barrel 700, until the movable part 120 is pressed against the mounting seat 110, so that the first sealing part 170 is elastically deformed to seal the gap between the mounting seat 110 and the movable part 120. At this time, the pressing plate 300 continues to descend and starts to extrude the material 800 until it abuts against the bottom wall of the barrel 700 to press all the material 800 out of the barrel 700. When the material pressing plate 300 completes pressing, the material pressing plate 300 starts to rise. At this time, the barrel 700 is separated from the material pressing plate under the restriction of the second limiting part 210. At the same time, the first linear driving structure 140 of the material pressing automatic exhaust structure 100 is actuated to drive the movable member 120 to move downward and open the ventilation channel 111. Subsequently, the operator pulls out the plug plate, and then the driving device 400 drives the material pressing plate 300 to descend, and brings the barrel 700 down to the feeding position, and finally the operator pulls out the barrel 700.
