When the pressure plate is not parallel to the container, gaps will appear between the pressure plate and the container, thus making it impossible to achieve a seal. Utility Model Content

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Example 1

[0024] like Figure 1As shown, this embodiment includes a lifting mechanism 10 and a fixed seat 20 connected to the lifting mechanism 10. In this embodiment, the lifting mechanism 10 is arranged vertically, so that the fixed seat 20 can move up and down on the lifting mechanism 10 through the operation of the lifting mechanism 10.

[0025] like Figure 2 As shown, the lifting mechanism 2 includes a mounting base 11, a left lead screw plate 12 and a motor mounting plate 13 disposed at both ends of the mounting base 11, and a lifting motor 14 is disposed on the side of the motor mounting plate 13 opposite to the left lead screw plate 12; a right lead screw plate 16 is disposed on the mounting base 11 and at one end near the motor mounting plate 13; wherein, the output shaft of the lifting motor 14 passes through the motor mounting plate 13 and is connected to a coupling 17, one end of the coupling 17 passes through the right lead screw plate 16 and is connected to a lead screw 18, and the end of the lead screw 18 away from the right lead screw plate 16 is rotatably connected to the left lead screw plate 12; and a lead screw nut 19 is disposed on the lead screw 18; in this embodiment, the coupling 17 is rotatably connected to the right lead screw plate 16 through a bearing;

[0026] The mounting base 11 is provided with a slide rail 15; in this embodiment, the bottom of the lead screw nut 19 is slidably connected to the slide rail 15; thus, through the operation of the lifting motor 14, the coupling 17 and the lead screw 18 are driven to rotate synchronously, so that the lead screw nut 19 moves up and down on the lead screw 18, and at the same time, stable lifting and lowering can be achieved through the slide rail 15, that is, the side of the lead screw nut 19 facing the slide rail 15 is provided with a slide groove that is slidably connected to the slide rail 15.

[0027] In one embodiment, the lifting motor 14 is also connected to an encoder; the encoder records the number of rotations of the lifting motor 14 to achieve precise displacement of the lead screw nut 19.

[0028] like Figure 1 As shown, a synchronization plate 30 is provided on the top of the fixed base 20, and a pressure plate 50 is provided on the side of the fixed base 20 opposite to the synchronization plate 30. Guide shafts 60 are fixedly connected to the four corners of the synchronization plate 30, and the lower end of the guide shaft 60 passes through the pressure plate 50. A limit component is connected to the end of the guide shaft 60 away from the synchronization plate 30. In this embodiment, a pressure plate through hole 51 is provided on the pressure plate 50 for the guide shaft 60 to pass through. The longitudinal dimension of the fixed base 20 is smaller than the longitudinal dimension of the synchronization plate 30, so that the lower end of the guide shaft 60 passes through the pressure plate 50.

[0029] like Figure 3 As shown, the limiting assembly includes a limiting member 70, a bolt 71, and an internally threaded hole 72 at the bottom of the guide shaft 60. The size of the limiting member 70 is larger than the diameter of the pressure plate through hole 51. Thus, the bolt 71 passes through the limiting member 70 and is fixedly connected to the internally threaded hole 72 at the bottom of the guide shaft 60. As a result, the pressure plate 50 is positioned on the limiting member 70 by a compression spring 45 (described in detail below).

[0030] A compression spring 45 is sleeved on the guide shaft 60 on the pressure plate 50; a fixing plate 40 is fixedly connected to the side of the fixing seat 20 opposite to the synchronous plate 30, and the compression spring 45 is located between the fixing plate 40 and the pressure plate 50; in this embodiment, the size of the fixing plate 40 is larger than the size of the fixing seat 20; a sealing gasket 52 is provided on the side of the pressure plate 50 opposite to the fixing plate 40, and a container 53 is provided below the sealing gasket 52; in addition, the size of the sealing gasket 52 is smaller than the size of the pressure plate 50.

[0031] In addition, a guide sleeve 31 is fitted on the guide shaft 60 located between the synchronization plate 30 and the fixed plate 40; thereby, the minimum distance between the synchronization plate 30 and the fixed plate 40 can be limited by the guide sleeve 31.

[0032] Thus, when the lifting mechanism 10 operates, the fixed seat 20 and the fixed plate 40 descend synchronously. At the same time, the compression spring 45 between the fixed plate 40 and the pressure plate 50 generates a clamping force, causing the sealing gasket 52 at the bottom of the pressure plate 50 to fit against the container 53. When a gap appears between the sealing gasket 52 at the bottom of the pressure plate 50 and the container 53, the compression spring 45 between the fixed plate 40 and the pressure plate 50 generates a clamping force, allowing the pressure plate 50 to drive the sealing gasket 52 and the container 53 to be further pressed and fitted together, achieving a seal between the sealing gasket 52 and the container 53. At the same time, the pressure plate 50 and the sealing gasket 52 can adaptively adjust their angles as they come into contact with the container 53, ensuring that the sealing gasket 52 and the container 53 always remain in contact, thereby reducing the positional accuracy requirements of the sealing gasket 52 and the container 53.

[0033] In this embodiment, the upper end of the compression spring 45 is fixedly connected to the fixed plate 40, and the lower end is fixedly connected to the pressure plate 50; thus, the compression spring 45 can automatically change the compression amount as the distance between the fixed plate 40 and the pressure plate 50 changes; and it is fixed to the bottom of the pressure plate 50 by the sealing gasket 52. When the pressure plate 50 moves downward, it can contact the container 53, and the compression of the compression spring 45 can further press the two together to achieve a sealing effect.

[0034] When the sealing gasket 52 is not parallel to the container 53, part of the sealing gasket 52 will contact the container 53 first. As the sealing gasket 52 continues to descend, the four guide shafts 60 on the synchronization plate 30 can adapt to the unevenness of the gap between the container 53 and the sealing gasket 52, so that the sealing gasket 52 and the container 53 always maintain contact and achieve a good sealing state.

[0035] In this embodiment, the sealing gasket 52 is a flexible material that can effectively seal the container 53 under the working force of the compression spring 45, so that even if there is liquid in the container 53, it will not overflow.

[0036] The upper part of the mounting base 11 is provided with an upper limit sensor 25 and the lower part with a lower limit sensor 26; a sensing plate 27 is provided on one side of the lead screw nut 19; in this embodiment, the upper limit sensor 25, the lower limit sensor 26 and the sensing plate 27 are all located on the same surface; thus, the contact between the upper limit sensor 25 or the lower limit sensor 26 and the sensing plate 27 can realize the separation or compression sealing between the sealing gasket 52 and the container 53.

[0037] The synchronization plate 30 has a through slot 32, such as Figure 4 As shown, the fixed base 20 is provided with at least two motor columns 35, and the at least two motor columns 35 extend out of the through slot 32 and are connected to a rotary motor 36. The output shaft of the rotary motor 36 is connected to a rotary coupling 37, and the rotary coupling 37 is connected to a rotary shaft 38. One end of the rotary shaft 38 passes through the through slot 32, the fixed base 20, and the fixed plate 40 in sequence and is connected to a cutter head. In this embodiment, there are four motor columns 35, and the synchronous plate 30 has a synchronous plate through hole with a size larger than that of the rotary motor 36. This allows the rotary motor 36 and the four motor columns 35 to move up and down on the synchronous plate through hole.

[0038] In this embodiment, the pressure plate 50 has a pressure plate through hole for the blade to pass through; the diameter of the pressure plate through hole is larger than the diameter of the blade, and a pressure plate sealing gasket is provided above the blade and on the rotating shaft 38 to seal the pressure plate through hole; thus, the blade can be used to crush ice cubes, juice, etc.

[0039] The working principle of this utility model is as follows:

[0040] The sealing gasket 52 is detached from the container 53, and the sensing plate 27 is in contact with the upper limit sensor 25. Upon receiving the work command, the lifting motor 14 rotates, causing the fixed seat 20 to descend. When the sealing gasket 52 contacts the container 53, it stops descending, while the lifting motor 14 continues to operate, and the fixed seat 20 continues to descend. At this time, the compression spring 45 is gradually compressed, making the pressure plate 50 press even tighter against the container 53, until the sensing plate 27 contacts the lower limit sensor 26. At this point, the fixed seat 20 stops moving, the rotary motor 36 rotates, and the rotary shaft 38 rotates. The blades mounted on the rotating shaft 38 can be used to crush ice cubes, juice, etc. Since the sealing gasket 52 is a flexible material, it can effectively seal the container 53 under the working force of the compression spring 45, so that liquid in the container 53 will not overflow even when it is being stirred. When the set rotation speed is reached, the fixed seat 20 rises again. At this time, the compression of the compression spring 45 gradually decreases, and the working force gradually decreases. When the pressure plate 50 is separated from the container 53, the length of the compression spring 45 no longer changes, and the fixed seat 20 rises until the sensing plate 27 contacts the upper limit sensor 25.

[0041] Example 2

[0042] The difference between this embodiment and embodiment 1 is that the synchronization plate 30 is provided with at least two motor columns 35, and a rotary motor 36 is provided on the at least two motor columns 35; in this embodiment, there are four motor columns 35.

[0043] The output shaft of the rotary motor 36 is connected to a rotary coupling 37, which is connected to a rotary shaft 38. One end of the rotary shaft 38 passes through a timing plate 30, a fixed seat 20, a fixed plate 40, a pressure plate 50, and a sealing gasket 52 in sequence and is connected to a cutting head.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the technical solutions of this utility model have been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
