[0040] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application will be further described in detail below in combination with the drawings and examples.

[0041] The present embodiment provides a liquid removal method, comprising the following steps: pumping gas into the liquid inlet of the product from which liquid is to be removed, driving the product to make reciprocating tilting motion between a first direction and a second direction opposite to the first direction until the liquid in the product is discharged outward under the combined action of its own gravity and the pushing force of the gas, wherein the first direction can be understood in the present embodiment as tilting the product 10 to the left, and the second direction can be understood in the present embodiment as tilting the product 10 to the right. Figure 2 The present embodiment provides a liquid removal method, comprising the following steps: pumping gas into the liquid inlet of the product from which liquid is to be removed, driving the product to make reciprocating tilting motion between a first direction and a second direction opposite to the first direction until the liquid in the product is discharged outward under the combined action of its own gravity and the pushing force of the gas, wherein the first direction can be understood in the present embodiment as tilting the product 10 to the left, and the second direction can be understood in the present embodiment as tilting the product 10 to the right. Figure 3 Compared with the prior art, in addition to continuously pumping gas into the liquid inlet of the product (i.e. continuously blowing gas into the product), the present method also drives the product to make reciprocating tilting motion in the first direction and the second direction, so that the liquid in the product can be discharged outward under the combined action of its own gravity and the pushing force of the gas. The present liquid removal method is suitable for the case where the product has a complex liquid path with multiple layers, and is particularly suitable for the case where the liquid inlet on the product is lower than the liquid outlet. The present liquid removal method can clean the liquid in the product with a complex liquid path more thoroughly.

[0042] Please refer to Figures 1 to 9 , the present embodiment also provides a bidirectional shaking device for realizing the step of making the product in the liquid removal method described above make reciprocating tilting motion in the first direction and the second direction. The bidirectional shaking device mainly comprises a rack 1, a tilting plate 2 and two driving mechanisms 3. The tilting plate 2 is used to directly or indirectly bear the product 10. The two driving mechanisms 3 are both connected to the rack 1, and are both arranged at the two ends of the tilting plate 2 and connected to the tilting plate 2. The right driving mechanism 3 is used to push the tilting plate 2 to tilt to the left as shown in Figure 2The left side is shown to be tilted to the left, and a driving mechanism 3 on the left side is used to push the tilting plate 2 to tilt to the left as shown Figure 3 The right side is shown to be tilted to the right. Preferably, the tilting plate 2 is further provided with a rotating plate 4, the rotating plate 4 and the tilting plate 2 are connected through bearings, and the rotating plate 4 is used to place the product 10. By providing the rotating plate 4, the product 10 can be rotated to an appropriate angle before being tilted to the left or the right, so as to ensure that the liquid in the product 10 with a complex liquid path of multiple layers can be completely discharged outward under the combined action of blowing and bidirectional shaking.

[0043] Please refer to Figures 1 to 5 , preferably, the rack 1 is provided with a conveying mechanism 5, and the rack 1 comprises a jacking mechanism 11 located at the middle part of the conveying mechanism 5. The conveying mechanism 5 is used to drive the product to move, and can be a belt conveying line. The jacking mechanism 11 is used to simultaneously jack up the two driving mechanisms 3, the tilting plate 2 and the rotating plate 4. In operation, the conveying mechanism 5 drives the product to be drained to above the rotating plate 4, and then the jacking mechanism 11 drives the two driving mechanisms 3, the tilting plate 2 and the rotating plate 4 to be jacked up. The rotating plate 4 drives the upward movement of the product 10 above to move upward and away from the conveying mechanism 5. Then, the tilting plate 2, the rotating plate 4 and the product are reciprocally tilted to the left and the right under the driving of the two driving mechanisms 3. After the product 10 is completely drained, the two driving mechanisms 3 drive the tilting plate 2, the rotating plate 4 and the product 10 to restore to a horizontal posture, and then the jacking mechanism 11 drives the two driving mechanisms 3, the tilting plate 2, the rotating plate 4 and the product 10 to move downward, so that the product 10 that has been drained is placed on the conveying mechanism 5 again. Finally, the conveying mechanism 5 drives the product 10 to be discharged to a designated position. As can be seen from the above, based on the design that the product 10 is automatically fed and discharged by the conveying mechanism 5, the jacking mechanism 11 is provided, so that the product 10 can be tilted to the left or the right at a higher height. The purpose is to prevent the product 10 from colliding with the conveying mechanism 5 or other components on the rack 1 when the product 10 is tilted to the left or the right.

[0044] In other embodiments, if the product 10 is manually fed and discharged to the rotating plate 4, and the height of the rotating plate 4 is high enough so that the rotating plate 4 does not collide with other components when it is tilted, then the bidirectional shaking device can not be provided with the jacking mechanism 11.

[0045] Please refer to Figure 4 and Figure 5The jacking mechanism 11 of the embodiment specifically comprises a base 111, a jacking device 112 and a lifting seat 113. The base 111 is fixed and invariable. The jacking device 112 is fixed on the base 111. The jacking device 112 is preferably a low-cost air cylinder. The lifting seat 113 is slidingly connected with the base 111 in the vertical direction through the cooperation of a linear bearing and a guide rod. The jacking device 112 is connected with the lifting seat 113. The jacking device 112 is used to drive the lifting seat 113 to move relative to the base 111 in the vertical direction. The two driving mechanisms 3 are both connected with the lifting seat 113. When the lifting seat 113 moves in the vertical direction under the drive of the jacking device 112, the two driving mechanisms 3, the inclined plate 2 and the rotating plate 4 can all move in the vertical direction together with the lifting seat 113.

[0046] Please refer to Figures 4 to 9 , the two driving mechanisms 3 specifically comprise a driver 31, a hinged seat 32 and a limiting assembly 33. The hinged seat 32 on the two driving mechanisms 3 is respectively rotationally connected with the inclined plate 2 (the relative rotation positions are M in Figure 8 and N in Figure 9 ). The bottom end of the driver 31 is rotationally connected with the lifting seat 113 (the relative rotation position is P shown in Figure 9 ). The top end of the driver 31 is fixedly connected with the hinged seat 32. The driver 31 is preferably a low-cost air cylinder. In fact, the driver 31 comprises a cylinder body 311 and a piston rod 312 which is retractable relative to the cylinder body 311. One of the cylinder body 311 and the piston rod 312 is rotationally connected with the lifting seat 113 at P. The other is fixedly connected with the hinged seat 32. When the piston rod 312 is extended upward, the driver 31 will drive the hinged seat 32 to move in the vertical direction. The limiting assembly 33 is connected with the lifting seat 113 and is used to limit or unlock the position of the hinged seat 32 relative to the lifting seat 113. Specifically, Figure 7The state that the shown tilt plate 2 and product 10 are tilted to the left is taken as an example for illustration, at this time the hinge seat 32 in the left drive mechanism 3 is limited in position by the limiting assembly 33, that is, at this time the hinge seat 32 in the left drive mechanism 3 is fixed relative to the lifting seat 113, while the hinge seat 32 in the right drive mechanism 3 is not limited in position by the limiting assembly 33, that is, at this time the hinge seat 32 in the right drive mechanism 3 is in the unlocked state of being liftable relative to the lifting seat 113, then only need the driver 31 in the right drive mechanism 3 to push the corresponding hinge seat 32 to move upward (in this process the right driver 31 will rotate a little angle to the left relative to the lifting seat 113), that is, the function that the tilt plate 2 and product 10 are jointly tilted to the left relative to the hinge seat 32 can be realized. Similarly, when the tilt plate 2 and product 10 need to be tilted to the right together, only need the hinge seat 32 in the right drive mechanism 3 to be limited in position by the corresponding limiting assembly 33, then the driver 31 in the left drive mechanism 3 pushes the corresponding hinge seat 32 to move upward (in this process the left driver 31 will rotate a little angle to the right relative to the lifting seat 113), that is, the tilt plate 2 and product 10 can be jointly tilted to the right.

[0047] Please refer to Figure 8 and Figure 9 , preferably, the hinge seat 32 is provided with a limiting hole 321, the limiting assembly 33 specifically comprises a connected executor 331 and a latch 332, the executor 331 is fixed on the lifting seat 113, the executor 331 is preferably a low-cost air cylinder, the executor 331 is used to drive the latch 332 to be inserted into the limiting hole 321 or to be separated from the limiting hole 321. When the latch 332 is inserted into the limiting hole 321, that is, the hinge seat 32 is limited in position by the limiting assembly 33 so that the hinge seat 32 is in the state of being fixed relative to the lifting seat 113; when the latch 332 is not inserted into the limiting hole 321, that is, the hinge seat 32 is not limited in position by the limiting assembly 33 so that the hinge seat 32 is in the unlocked state of being liftable relative to the lifting seat 113. Further preferably, the opposite sides of the hinge seat 32 are both provided with limiting holes 321, the two drive mechanisms 3 both comprise two limiting assemblies 33, the latch 332 of one limiting assembly 33 is used to be inserted into the limiting hole 321 on one side and is used to abut against the hinge seat 32 in the axial direction, and the latch 332 of the other limiting assembly 33 is used to be inserted into the limiting hole 321 on the other side and is used to abut against the hinge seat 32 in the axial direction. Through such design, the reliability and stability of the locking position of the hinge seat 32 can be improved, thereby being beneficial to improving the reliability and stability of the left or right tilting of the tilt plate 2 and product 10 together.

[0048] Please refer to Figure 10 and Figure 11The two-way shaking device further comprises a collecting box 6, a collecting cavity 61 is arranged in the collecting box 6, liquid inlet holes 62 which communicate with the collecting cavity 61 are arranged on the outer wall of the collecting box 6, the liquid inlet holes 62 are used for communicating with liquid outlet holes on the product 10 to collect the liquid blown out from the product 10, since the present scheme is used for removing liquid by blowing, the liquid received in the collecting box 6 is accompanied by a large amount of gas, in order to prevent the collecting cavity 61 from exploding due to excessive internal gas pressure, it is necessary to arrange a pressure relief hole 63 on the collecting cavity 61, the pressure relief hole 63 communicates the outside and the collecting cavity 61 to discharge the gas in the collecting cavity 61. However, since the liquid enters the collecting cavity 61 in a high-pressure state under the driving of the gas, the liquid will splash outwards from the pressure relief hole 63 after entering the collecting cavity 61, in order to solve the problem of liquid splashing outwards, the present scheme is arranged with foam 7 in the collecting cavity 61, and the foam 7 is arranged in the extension direction of the liquid inlet hole 62 and the extension direction of the pressure relief hole 63. Specifically, the liquid entering from the liquid inlet hole 62 will be blocked by the foam 7, the liquid will not directly hit the bottom wall of the collecting cavity 61 due to the blocking of the foam 7, the liquid will be buffered in the foam 7 and then flow downwards, thereby greatly reducing the amount of internal liquid splashing outwards from the pressure relief hole 63, at the same time, the pressure relief hole 63 is also blocked by the foam 7, so that the liquid in the collecting cavity 61 is more difficult to splash outwards from the pressure relief hole 63, the foam 7 has good air permeability due to the porous structure, therefore, even if the pressure relief hole 63 is blocked by the foam 7, it will not affect the external discharge of the internal gas from the pressure relief hole 63, to ensure that the collecting box 6 can realize the purpose of preventing liquid from splashing outwards on the premise of being able to discharge pressure externally.

[0049] The present embodiment also provides a liquid removing device, in addition to comprising the above-mentioned two-way shaking device, further comprising a gas source, the gas source is used for pumping gas to the liquid inlet of the product, through the combination use of the gas source and the two-way shaking device, the liquid in the product can be discharged outwards under the joint action of the self-gravity and the thrust of the gas, so that the liquid in the product with a complex liquid path can be cleaned more cleanly.

[0050] The above is only a preferred embodiment of the present application, only the technical principle of the present application is specifically described, these descriptions are only for explaining the principle of the present application, and cannot be explained as the limitation of the protection scope of the present application in any way. Based on the explanation here, any modification, equivalent replacement and improvement within the spirit and principle of the present application, and other specific embodiments of the present application which can be thought by those skilled in the art without creative labor, should be included in the protection scope of the present application.
