[0002] In the process of outputting and packaging the liquid material in the barrel, some people use pressure pumps to extract the liquid material. However, due to the flat bottom of the barrel, especially for liquid materials with relatively high viscosity, the extraction effect of the pressure pump is generally poor, and a lot of liquid material will remain in the barrel, causing great waste.

[0003] In the process of conveying and packaging some special materials, it is necessary to ensure that no bubbles are generated during the conveying and filling of the materials. However, the current common presses are prone to generate a large number of bubbles in the materials during the extrusion process, so it is difficult to meet the filling requirements.

[0037] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with the embodiments and drawings, and the contents mentioned in the implementation manner are not intended to limit the present invention. The present invention is described in detail below in conjunction with the drawings.

[0038] The embodiment of the utility model provides a vacuum material pressing and extruding device, which can evacuate the internal space of the barrel 1 to eliminate the bubbles in the material, and press the material down through the pressure plate 5 to transport it to other containers. Figure 1-5 As shown, a vacuum pressing and extruding device provided in this embodiment includes a barrel 1, a frame 2, a cover 3, a pressing device 4 and a pressure plate 5, wherein the barrel 1 is used to contain materials, and a discharge valve 11 for extruding the materials is arranged at the bottom of the barrel 1, and during the extrusion process of the materials, the discharge valve 11 is connected to other containers through a pipeline. The frame 2 includes a crossbeam 21 suspended above the barrel 1, and support legs 22 are respectively provided at both ends of the crossbeam 21; the pressing device 4 is fixedly installed on the crossbeam 21, and has an execution end 41 extending or retracting toward the inside of the barrel 1, and a hole for the execution end to pass through and be tightly connected is provided on the cover body 3, and the end of the execution end 41 after passing through the cover body 3 is fixedly connected to the pressing plate 5, wherein the cover body 3 is used to seal the barrel mouth of the barrel 1, and an exhaust hole 31 is provided on the cover body 3, which is used to communicate with an external vacuum pump through a pipeline, so that the inside of the barrel 1 can be vacuumed, so that the inside of the barrel 1 is maintained at a predetermined air pressure, and then the bubbles in the material and the air dissolved in the material are extracted, and the activity of the pressing plate 5 is sealed. It is connected inside the barrel 1 and can move toward the bottom of the barrel 1 under the drive of the pressing device 4, thereby squeezing the material, so that the material can be squeezed and transported to other containers in a vacuum environment. At the same time, in order to change the air pressure in the upper and lower spaces of the pressing plate 5 when the pressing plate 5 moves toward the material, a one-way valve 51 is provided on the pressing plate 5 and penetrates the thickness of the pressing plate 5. Therefore, when the pressing plate 5 moves toward the material, the air pressure in the lower and upper spaces of the pressing plate 5 is ensured to be the same. At the same time, when the pressing plate 5 squeezes the material, the material resists the one-way valve 51, which can close the one-way valve 51, thereby preventing the material from entering the upper space of the pressing plate 5 along the one-way valve 51.

[0039] In this embodiment, the pressure plate 5 is configured with a diameter size that matches the inner diameter of the barrel 1, and a seal 52 is also provided on the circumferential surface of the pressure plate 5, so as to ensure the sealing performance between the pressure plate 5 and the inner wall of the barrel 1. It is worth noting that the sealing performance between the pressure plate 5 and the barrel 1 is relatively high, and it is sufficient to prevent the material from entering the upper space of the pressure plate 5 along the gap between the pressure plate 5 and the barrel 1. In this embodiment, the pressing device 4 is a hydraulic cylinder, the cylinder body of the hydraulic cylinder is fixedly mounted on the crossbeam 21, and the piston rod of the hydraulic cylinder extends through the cover body 3 toward the inside of the barrel 1 and is fixedly connected to the pressure plate 5. The hydraulic cylinder can make the pressure plate 5 have a greater pressure in the process of squeezing the material, so that the pressing material can be conveyed more smoothly.

[0040] In this embodiment, when the internal space of the barrel 1 is vacuumed, the pressing device 4 pulls the pressure plate 5 upward so that the pressure plate 5 is at the top of the cover body 3, and the air suction holes 512131 are arranged on the circumferential surface of the cover body 3, and the distance between the air suction holes 31 and the top of the cover body 3 is greater than the thickness of the pressure plate 5, so that the pressure plate 5 will not cause interference in the process of vacuuming the inside of the barrel 1, and at the same time, the space inside the entire barrel 1 can be vacuumed.

[0041] In the process of squeezing and extruding the material inside the barrel 1, the space inside the cover 3 of the barrel 1 is sealed to form a closed space. At this time, the vacuum pump evacuates the space inside the barrel 1 through the air extraction hole 31, so that the bubbles inside the material and the air dissolved therein can be extracted, and the barrel 1 can be kept within a predetermined air pressure range. The pressing device 4 drives the pressing plate 5 to squeeze the material inside the barrel 1. By squeezing and conveying the material under a vacuum environment, it can be ensured that no bubbles are generated during the conveying process of the material, and the conveying and storage needs of the material can be met. It is worth noting that when the pressing plate 5 is downward During the movement, the one-way valve 51 located on the pressure plate 5 is in an open state, so that during the movement of the pressure plate 5, there will not be a large difference in the air pressure in the spaces above and below the pressure plate 5, which will affect the performance of the pressure plate 5 and the barrel 1. When the pressure plate 5 and the material are in contact with each other and the material is squeezed and conveyed, the material closes the one-way valve 51, thereby preventing the material from entering the upper space of the pressure plate 5 along the one-way valve 51 during the pressing process. Through the technical solution provided in this embodiment, air and bubbles in the material can be eliminated, and the material can be squeezed and conveyed in a vacuum environment, thereby meeting the transportation and storage requirements of special materials.

[0042] In this embodiment, in order to ensure the stability of the movement of the pressure plate 5 during the downward pressing process, a guide rod 53 is further provided on the pressure plate 5. One end of the guide rod 53 is fixedly connected to the pressure plate 5, and the other end is slidably connected to the cover body 3 in a sealed manner in the vertical direction and extends upward. It is conceivable that a hole is provided on the cover body 3 for the guide rod 53 to pass through and be slidably connected therein in a sealed manner, so as to ensure the stability of the pressure plate 5 during the downward and upward movement.

[0043] At the same time, in order to monitor the limit position of the rise of the pressure plate 5, a detection member 23 corresponding to the end of the guide rod 53 is arranged on the crossbeam 21, and the detection member 23 is connected to the signal of the pressing device 4. In this embodiment, the detection member 23 is a photoelectric sensor switch, and the photoelectric sensor switch is connected to the controller of the pressing device 4. During the rise of the guide rod 53 (that is, the rise of the pressure plate 5), the signal at the end of the guide rod 53 is detected by the photoelectric sensor switch, and the detection signal is transmitted to the controller, so that the controller controls the pressing device 4 to stop. It can ensure that the pressure plate 5 will not cause damage to the cover body 3 in the continuous rise, and avoid unnecessary energy consumption.

[0044] In this embodiment, if Figure 4-5 As shown, the one-way valve 51 includes a valve body 511, a valve cover 512, a valve core 513 and an elastic member, wherein a channel 5111 is opened on the valve body 511, and an inlet and an outlet are set at both ends of the channel 5111, and the inlet 5112 end is set as an inclined sealing surface 5114; the valve cover 512 is opened at the inlet end 5112 of the valve body 511, and a vent hole 5121 is opened on the valve cover 512; the valve core 513 is inserted in the channel 5111, and includes a rod body 5131 and A sealing head 5132 is formed at one end of the rod body 5131, and the sealing head 5132 is provided with an inclined surface adapted to the sealing surface 5114. A connecting rod is also provided on the rod body 5131, and one end of the connecting rod is fixedly connected to the rod body 5131, and the other end passes through the valve cover 512 and is formed with a limiting portion to prevent the valve body 511 from falling within the channel 5111. An elastic member is provided between the rod body 5131 and the valve cover 512 to provide an elastic force downward to the valve core 513. In this embodiment, the elastic member is a spring, which is mounted on the connecting rod. In order to ensure the stability of the movement of the valve core 513 in the channel 5111, the diameter of the rod and the inner diameter of the channel 5111 are designed to be substantially the same size, so that the valve core 513 can move stably in the channel 5111. At the same time, in order to ensure the ventilation performance of the one-way valve 51, at least one air channel 5133 extending axially is provided on the circumferential surface of the rod body 5131, so that when the sealing head 5132 and the sealing surface 5114 are separated from each other, the air channel 5133 can connect the inlet 5112 and the outlet 5113 of the valve body 511 to each other.

[0045] In this embodiment, the pressing extrusion equipment is also equipped with a lifting assembly 6 for lifting the frame 2. The lifting assembly 6 includes a base 61 and a lifting drive device 62. The lifting drive device 62 is provided with two mutually parallel parts and is respectively connected to the two ends of the beam 21 to drive the beam 21 to rise or fall in the vertical direction. The frame 2 is lifted by the lifting drive device 62, so that the space under the frame 2 is increased to facilitate placing the barrel 1 under the cover 3, and to facilitate the assembly of the pressure plate 5 and the cover 3 with the barrel 1. In this embodiment, the lifting drive device 62 can be configured as a hydraulic cylinder similar to the pressing device 4, or it can be other devices such as a cylinder that can lift the frame 2, again without limitation.

[0046] At the same time, if Figure 1-2 As shown, the frame also includes a base frame 23 arranged at the lower part of the supporting leg 22. The base frame 23 is a plate-shaped structure for supporting the barrel 1. In the present embodiment, the barrel 1 is provided with four rollers at the bottom of the barrel for easy movement. Correspondingly, there is an escape position for the rollers to pass through on the base frame 23 in the present embodiment, so that the barrel 1 is placed on the upper side of the base frame 23. When the material in the barrel 1 needs to be squeezed and extruded, the lifting assembly 6 drives the frame 2 to rise. At this time, the base frame 23 gradually approaches the bottom of the barrel 1 and gradually lifts the barrel 1. At the same time, the discharge valve 11 of the barrel 1 is lifted to facilitate the discharge.
