[0026] Specifically, the operation steps of using the pressing device for tofu processing to press and form tofu are as follows: first, place the cloth bag containing soybean milk on the support plate 23, and at this time the cloth bag is located in the movable frame 2; move the movable frame 2 to move the movable frame 2 together with the cloth bag to the lower side of the lower pressing assembly 4; at this time, the movable frame 2 is placed on the support frame 13, and the cloth bag is placed between the lower pressing plate 41 and the liquid storage tank 14; start the second driving assembly to drive the lower pressing plate 41 to descend and press on the cloth bag to extrude the cloth bag; the water in the soybean milk is extruded and then enters the liquid storage tank 14 through the second liquid leakage hole 24 and the first liquid leakage hole 22 or the opening 21 in sequence, so that the pressing and forming of tofu is completed, and the lower pressing plate 41 is reset under the driving of the second driving assembly after the pressing is completed; when the tofu is taken out after the pressing is completed, move the movable frame 2 to the upper side of the slot 12, start the first driving assembly to drive the jacking plate 31 to rise, so that the support plate 23 is pushed by the jacking plate 31 to rise in the movable frame 2, until the cloth bag placed on the support plate 23 is separated from the movable frame 2, at this time the pressed tofu can be taken out from the movable frame 2. The pressing device for tofu processing provided in the embodiment can quickly take out the pressed tofu, thereby improving the production efficiency of tofu products, and the pressing and taking out operations are simple and convenient to use.

[0027] As shown in Figure 2 and Figure 5 The guide rail 15 is arranged on the rack 1, the length direction of the guide rail 15 is consistent with the moving direction of the movable frame 2, and the movable frame 2 is provided with a sliding block 25 matched with the guide rail 15. The guide rail 15 arranged on the rack 1 is used to cooperate with the sliding block 25 on the movable frame 2 to guide the movement of the movable frame 2 on the rack 1, prevent the movable frame 2 from deviating from the preset direction when moving, ensure that the movable frame 2 can accurately move to the upper side of the ejection assembly 3 or the lower side of the lower pressing assembly 4, and reduce the friction between the movable frame 2 and the rack 1, thereby improving the stability of the movable frame 2 when moving.

[0028] In the embodiment, the opposite ends of the guide rail 15 are respectively provided with a positioning assembly 5, which comprises a positioning cylinder 51, the positioning cylinder 51 is internally provided with a positioning bead 52 and a spring 53 abutting against the positioning bead 52, the positioning cylinder 51 is provided with a through hole 54 through which part of the positioning bead 52 passes, and the slide block 25 is provided with a positioning hole 26 accommodating part of the positioning bead 52 and the cross section of the positioning hole 26 is triangular. The positioning assembly 5 at the two ends of the guide rail 15 cooperates with the positioning hole 26 on the slide block 25 to position the movable frame 2, when the slide block 25 moves to the end of the guide rail 15, i.e. the movable frame 2 moves above the ejecting assembly 3 or below the pressing-down assembly 4, part of the positioning bead 52 is driven by the elasticity provided by the spring 53 to pass through the through hole 54 and extend into the positioning hole 26, thereby hindering the movement of the slide block 25 on the guide rail 15, so as to prevent the movable frame 2 from producing unintended movement during the process of lifting on the jacking plate 31 or lowering on the pressing-down plate 41; when it is needed to move the movable frame 2, since the cross section of the positioning hole 26 is triangular, the positioning bead 52 moves along the side surface of the positioning hole 26 and retreats into the positioning cylinder 51 when the operator pushes or pulls the movable frame 2 with force, so that the positioning bead 52 exits the positioning hole 26 and further compresses the spring 53, at this time, the slide block 25 can smoothly move on the slide rail, when the movable frame 2 moves to the position where the positioning bead 52 is aligned with the positioning hole 26, the positioning bead 52 is driven by the spring 53 to pop out of the positioning cylinder 51 and enter the positioning hole 26, i.e. the movable frame 2 can be positioned again.

[0029] As shown in Figure 2 and Figure 3 , the movable frame 2 is internally provided with a vertical first guide rod 27, and the support plate 23 is provided with a first guide hole cooperating with the first guide rod 27. The first guide rod 27 is used to limit the movement direction of the support plate 23 on the movable frame 2, prevent the support plate 23 from deflecting or tilting when lifting in the movable frame 2, and ensure that the position of the pressed tofu on the support plate 23 remains stable when the support plate 23 pushes the pressed tofu out.

[0030] In detail, the movable frame 2 is further provided with a handle 28, and the height of the handle 28 is higher than the height of the opening 21 of the through slot 11. The handle 28 can be operated to push or pull the movable frame 2 to move in the through slot 11, thereby facilitating the adjustment of the position of the movable block.

[0031] Please refer to Figure 1 , Figure 2 and Figure 3The frame 1 is further provided with a mounting plate 6 covering the slot 12, and the first driving assembly includes a hydraulic cylinder 32 arranged on the mounting plate 6 and a piston rod 33 arranged at an output end of the hydraulic cylinder 32, one end of the piston rod 33 being matched with the jacking plate 31. The jacking plate 31 is moved under the driving of the piston rod 33 by extending or retracting the piston rod 33 into or out of the hydraulic cylinder 32. When the piston rod 33 extends out of the hydraulic cylinder 32, the jacking plate 31 enters the movable frame 2 through the opening 21 and pushes the support plate 23 to rise, and when the piston rod 33 retracts into the hydraulic cylinder 32, the jacking plate 31 exits the movable frame 2 through the opening 21 and returns to the slot 12, so as to control the movement of the jacking plate 31, and the hydraulic cylinder 32 is mounted on the mounting plate 6, facilitating the dismounting of the mounting plate 6 for maintenance when the pressing device for bean curd processing is overhauled.

[0032] Specifically, the jacking plate 31 is provided with a vertical second guide rod 34, and the mounting plate 6 is provided with a second guide hole matched with the second guide rod 34. The second guide rod 34 is arranged on the jacking plate 31, and the second guide hole matched with the second guide rod 34 is arranged on the mounting plate 6. When the jacking plate 31 moves under the driving of the first driving assembly, the second guide rod 34 slides in the second guide hole, preventing the jacking plate 31 from deviating from the preset direction and keeping the jacking plate 31 horizontal, which is beneficial to improve the stability of the support plate 23 when the support plate 23 is pushed by the jacking plate 31.

[0033] As Figure 2 and Figure 4As shown, the rack 1 is further provided with two supports 7, and the two supports 7 are respectively located at opposite sides of the through slot 11. The second driving assembly comprises a driving motor 42 and a driving screw 43 arranged at an output end of the driving motor 42. The opposite ends of the driving screw 43 are respectively and correspondingly rotatably connected with the two supports 7. Two thread portions 44 with opposite rotation directions are arranged on the driving screw 43 at intervals. Thread sleeves 45 corresponding to the two thread portions 44 are arranged on the driving screw 43. The thread sleeves 45 are respectively rotatably connected with connecting rods 46, and the connecting rods 46 are rotatably connected with the lower pressing plate 41 at the ends away from the thread sleeves 45. The driving motor 42 drives the driving screw 43 to rotate on the support 7. When the driving screw 43 rotates, the two thread sleeves 45 are simultaneously moved along the axial direction of the driving screw 43 under the driving of the corresponding thread portions 44. Since the two thread portions 44 have opposite rotation directions, the moving directions of the two thread sleeves 45 are opposite. When the thread sleeves 45 move, the connecting rods 46 push or pull the lower pressing plate 41 to move, so as to drive the lower pressing plate 41 to move up and down in the vertical direction. The number of rotations of the driving motor 42 can adjust the moving distance of the lower pressing plate 41 and the pressure generated by the lower pressing plate 41 on the cloth bag, so as to ensure that the bean curd is quickly pressed and formed. During the process of pressing the cloth bag by the lower pressing plate 41, the position of the lower pressing plate 41 can be locked by the cooperation between the thread sleeves 45 and the thread portions 44 after the driving screw 43 stops rotating, so as to prevent the lower pressing plate 41 from loosening during the pressing process.

[0034] In detail, the support 7 is provided with a vertical third guide rod 71, and the lower pressing plate 41 is provided with a third guide hole matched with the third guide rod 71. The third guide rod 71 arranged on the support 7 is used to cooperate with the third guide hole on the lower pressing plate 41 to limit the moving direction of the lower pressing plate 41, so as to avoid the unexpected deviation of the lower pressing plate 41, and make the lower pressing plate 41 smoothly enter or exit the movable frame 2, thereby improving the reliability of the pressing device for bean curd processing.

[0035] Please refer to Figure 2 , Figure 3 and Figure 4The frame 1 is further provided with a liquid guide pipe 16 communicated with the liquid storage tank 14, the bottom of the liquid storage tank 14 is provided with a flow guide surface 17, and the height of the side of the flow guide surface 17 close to the liquid guide pipe 16 is lower than the height of the side of the flow guide surface 17 far from the liquid guide pipe 16. The moisture squeezed out of the cloth bag falls into the liquid storage tank 14, is concentrated along the flow guide surface 17 to the liquid guide pipe 16, and is discharged out of the liquid storage tank 14 from the liquid guide pipe 16, so as to collect the moisture squeezed out of the cloth bag, avoid the moisture squeezed out of the cloth bag from staying in the liquid storage tank 14 to deteriorate and produce odor, and facilitate the flushing of the pressing device for tofu processing to keep the pressing device for tofu processing clean.

[0036] Finally, it should be pointed out that the above embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the present application, and all of them should be covered in the scope of the claims of the present application.
