DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] like Figures 1 to 11 As shown, a flat-plate fruit and vegetable slice quick freezing assembly of the present invention comprises a box body 1, and a side wall of the box body 1 has a box door 2. The box door 2 is connected to the box body 1 by a hinge to facilitate the opening and closing of the box door 2. Figure 2 As shown, the box 1 has a plurality of motion frames 4 arranged sequentially from top to bottom. The motion frames 4 are connected to the inner wall of the box 1 by sliding up and down. A group of lifting and lowering swing rods 5 are arranged outside each of the two adjacent motion frames 4. The two lifting and lowering swing rods 5 arranged in a group are connected by rotation. Transverse sliders 6 are installed on both ends of the lifting and lowering swing rods 5 by rotation. The transverse sliders 6 are connected to the outer wall of the motion frame 4 by sliding and the sliding direction is located in the horizontal plane. Two transverse sliders 6 are arranged on the outer wall of each motion frame 4, and the moving directions of the two transverse sliders 6 are always opposite. The lifting and lowering swing rods 5 and the transverse sliders 6 constitute a scissor-type telescopic mechanism. The box 1 has a driving member driving the scissor-type telescopic mechanism to telescope. A plurality of support plates 37 arranged sequentially from top to bottom are fixedly installed inside the motion frame 4. A pressing plate 8 is arranged above each support plate 37. An adjustment component for adjusting the height of the pressing plate 8 is arranged inside the box 1.

[0024] When in use, fruit and vegetable slices are placed between the support plate 37 and the pressing plate 8. The height of the pressing plate 8 relative to the support plate 37 is adjusted according to the thickness of the fruit and vegetable slices, thereby satisfying the quick freezing processing of fruit and vegetable slices of different thicknesses.

[0025] like Figure 4As shown, the adjustment assembly includes a lead screw 13, a nut 14, a connecting rod 15 and a driving mechanism. At least two lead screws 13 are rotatably connected to the motion frame 4 above each pressing plate 8. Both ends of the lead screw 13 are provided with a nut 14, and the movement directions of the two nuts 14 are always opposite. To achieve this purpose, a section of external thread can be provided at both ends of the lead screw 13, and the external threads at both ends of the lead screw 13 are rotated in opposite directions, thereby achieving that the movement directions of the two nuts 14 are always opposite. There is a connecting rod 15 between each nut 14 and the pressing plate 8, and the upper end of the connecting rod 15 is rotatably connected to the corresponding nut 14, and the lower end of the connecting rod 15 is rotatably connected to the corresponding pressing plate 8. The driving mechanism is located on the box body 1 and is used to drive the synchronous rotation of the lead screw 13. When the driving mechanism drives the lead screw 13 to rotate synchronously, the rotation of the lead screw 13 drives the movement of the nuts 14 at both ends of the lead screw, and the movement directions of the two nuts 14 on the lead screw 13 are opposite. The movement of the nut 14 pulls the pressing plate 8 upward or pushes the pressing plate 8 downward through the connecting rod 15, thereby realizing the up and down movement of the pressing plate 8 relative to the supporting plate 37.

[0026] like Figure 3 , Figure 4 As shown, the driving mechanism includes a driving motor 9, a driving shaft 10, a driven shaft 11 and a bevel gear transmission mechanism. The driving motor 9 is fixedly connected to the top of the box body 1. The driving shaft 10 and the driven shaft 11 are both rotatably connected to the box body 1. The driving shaft 10 and the driven shaft 11 are both vertically arranged and located between the inner wall of the box body 1 and the motion frame 4. The driving shaft 10 is fixedly connected to the output end of the driving motor 9. The driving shaft 10 and the driven shaft 11 act synchronously. The bevel gear transmission mechanism is located between the driving shaft 10 and the lead screw 13 and between the driven shaft 11 and the lead screw 13. When the driving shaft 10 and the driven shaft 11 rotate, the lead screw 13 is driven to rotate through the bevel gear transmission mechanism. In order to achieve the synchronous rotation of the driving shaft 10 and the driven shaft 11, as shown in FIG. Figure 3 As shown, a linkage mechanism 39 is provided between the driving shaft 10 and the driven shaft 11 . The linkage mechanism 39 may be a belt transmission mechanism or a chain transmission mechanism. When the driving shaft 10 rotates, the driven shaft 11 is driven to rotate through the linkage mechanism 39 .

[0027] like Figure 5As shown, the bevel gear transmission mechanism includes a first bevel gear 16 and a second bevel gear 17 that mesh with each other, wherein the first bevel gear 16 is fixed to the end of the lead screw 13, and the second bevel gear 17 is rotatably installed in the gear box 12, the gear box 12 is slidably connected to the housing 1 up and down, and the driving shaft 10 and the driven shaft 11 penetrate the corresponding gear box 12 from top to bottom. Along the axial direction of the driving shaft 10 and the driven shaft 11, the driving shaft 10 and the corresponding second bevel gear 17, and the driven shaft 11 and the corresponding second bevel gear 17 are all slidably connected up and down. Along the circumferential direction of the driving shaft 10 and the driven shaft 11, the driving shaft 10 and the corresponding second bevel gear 17, as well as the driven shaft 11 and the corresponding second bevel gear 17 are relatively fixed, so that when the driving shaft 10 and the driven shaft 11 rotate, the corresponding second bevel gear 17 can be driven to rotate, and then the corresponding first bevel gear 16 can be driven to rotate, and then the lead screw 13 can be driven to rotate, and then the nut 14 can be driven to move, and then the connecting rod 15 can be driven to swing, and then the pressure plate 8 can be driven to move up and down, so as to adjust the distance between the pressure plate 8 and the support plate 37.

[0028] The gear box 12 is located between the inner wall of the box body 1 and the moving frame 4. When the driving member drives the scissor-type telescopic mechanism to extend and retract, the transverse slider 6 moves along the outer wall of the moving frame 4, thereby changing the distance between two adjacent moving frames 4.

[0029] like Figure 3 As shown, the driving member is an electric cylinder 7, the cylinder body of the electric cylinder 7 is indirectly fixedly connected to the bottommost moving frame 4, and the piston rod of the electric cylinder 7 is fixedly connected to one of the bottommost transverse sliders 6. The indirect fixed connection method is: a mounting plate 40 is set at the lower part of the box body 1, the bottommost moving frame 4 is fixed on the mounting plate 40, and the cylinder body of the electric cylinder 7 is also fixedly connected to the mounting plate 40. When the piston rod of the electric cylinder 7 is extended, the transverse slider 6 connected thereto moves in a direction away from the opposite transverse slider 6, thereby reducing the distance between the two adjacent moving frames 4 above and below. When the piston rod of the electric cylinder 7 is retracted, the transverse slider 6 connected thereto moves in a direction close to the opposite transverse slider 6, thereby increasing the distance between the two adjacent moving frames 4 above and below, and then adjusting the distance between the two adjacent moving frames 4 through the action of the electric cylinder 7. When the moving frame 4 moves up and down, it drives the gear box 12 fixedly connected thereto to move up and down. At this time, the first bevel gear 16 in the gear box 12 moves axially along the corresponding driving shaft 10 or driven shaft 11, and the lead screw 13 moves up and down with the gear box 12.

[0030] like Figure 1 , Figure 2 As shown, a lifting assembly for adjusting the height of the box body 1 and a moving assembly for driving the box body 1 to move are arranged below the box body 1.

[0031] like Figure 3 , Figure 4 and Figure 6 As shown, the lifting assembly includes a telescopic rod 38 and a base 18 , the base 18 is located below the box body 1 , and the telescopic rod 38 is located between the base 18 and the box body 1 .

[0032] like Figure 7 As shown, the moving assembly includes a driving motor 19, a driving rod 20 and a sliding plate 21. The driving motor 19 is fixed on the base 18. The output end of the driving motor 19 is fixedly connected to the driving rod 20. The driving rod 20 is rotatably connected to the base 18. The two ends of the driving rod 20 are respectively provided with a sliding plate 21. The sliding plate 21 is slidably connected to the base 18 and the sliding plates 21 at both ends of the driving rod 20 move in opposite directions. There are at least two groups of supporting swing rods 22 between the two sliding plates 21. The two supporting swing rods 22 arranged in a group are hingedly connected, and one end of the supporting swing rod 22 is rotatably connected to the sliding plate 21 on the corresponding side, and the other end of the supporting swing rod 22 is movably connected to the bottom of the box body 1. The box body 1, the supporting swing rod 22, the sliding plate 21 and the base 18 constitute a scissor-type lifting mechanism. In order to realize that the sliding plates 21 at both ends of the driving rod 20 move in opposite directions, two sections of external threads with opposite rotation directions can be set at both ends of the driving rod 20, and the external thread part of the driving rod 20 passes through the sliding plate 21 and is threadedly matched with it.

[0033] like Fig.10 As shown, a limit block 25 is installed inside the sliding plate 21 for sliding movement, and a limit spring 26 is arranged between the limit block 25 and the sliding plate 21. When the limit spring 26 is at its natural length, most of the limit block 25 extends out of the sliding plate 21. Figure 7 As shown, the base 18 is provided with limit slots 24 at equal intervals inside, and when the limit block 25 extends into the limit slot 24, the sliding plate 21 and the base 18 are locked and fixed relative to each other. An electric push rod 27 is fixedly mounted on the sliding plate 21, and a mounting block 28 is fixedly mounted on the output end of the electric push rod 27, and a traction rope 29 is provided between the mounting block 28 and the limit block 25. When the electric push rod 27 contracts, the limit block 25 is pulled by the traction rope 29 to overcome the elastic force of the limit spring 26 and move toward the inside of the sliding plate 21, so that the limit block 25 moves out of the limit slot 24. At this time, after the driving motor 19 is started, the driving rod 20 rotates, thereby driving the sliding plate 21 to slide relative to the base 18, and then the two supporting swing rods 22 arranged in a group swing relative to each other, thereby driving the box body 1 to move up and down.

[0034] like Figure 8 , Fig. 9As shown, the moving assembly includes a lifting rod 30, a lifting plate 31 and a docking block 33. The upper end of the lifting rod 30 is fixedly connected to the box body 1, and the lifting rod 30 passes through the base 18 and is slidably connected to the base 18. The lifting plate 31 is installed inside the base 18 to slide up and down. The docking block 33 is fixed on the top of the lifting plate 31, and the docking block 33 is engaged with the lower end of the lifting rod 30. A roller assembly 32 is fixedly installed on the bottom of the lifting plate 31, and the roller assembly 32 is located below the base 18. When the roller of the roller assembly 32 rotates, it drives the base 18 to move. As shown in FIG. Figure 8 , Fig. 9 and Fig.11 As shown, the lower end of the lifting rod 30 has a mounting groove inside, and two symmetrically arranged clamping members 35 are arranged in the mounting groove. One end of the clamping member 35 is conical, and a locking spring 36 is arranged between the other ends of the two clamping members 35. When the locking spring 36 is in a natural state, one end of the clamping member 35 extends out of the mounting groove. The docking block 33 has a clamping groove 34. After one end of the clamping member 35 extends into the clamping groove 34, the docking block 33 and the lifting rod 30 are locked and fixed.

[0035] During the movement, the spatial position of the present invention can be adjusted directly by rolling the roller in the roller assembly 32. After the spatial position of the present invention is adjusted, the height of the present invention can be adjusted. During the upward movement of the box body 1, the box body 1 drives the lifting rod 30 to move upward synchronously, and during the upward movement of the lifting rod 30, the engagement of the engaging member 35 with the engaging groove 34 drives the docking block 33 to move upward. At this time, the docking block 33 drives the lifting plate 31 and the roller assembly 32 to move synchronously, and at this time, the roller assembly 32 can enter the interior of the base 18 to achieve hiding. During the process of the lifting rod 30 continuing to move upward, after the docking block 33 contacts the upper end of the base 18, the upper end of the base 18 prevents the docking block 33 from continuing to move upward, and the lifting rod 30 is separated from the docking block 33. During this process, the engaging groove 34 squeezes the engaging member 35 and causes the engaging member 35 to move toward the inside of the lifting rod 30. During the movement of the engaging member 35, the locking spring 36 is squeezed and the locking spring 36 is contracted. After the engaging member 35 is separated from the engaging groove 34, the lifting rod 30 can be separated from the docking block 33, so that the lifting rod 30 moves upward with the box body 1. When the box body 1 moves downward and resets, the engaging member 35 is engaged with the engaging groove 34 again, so that the roller assembly 32 supports the present invention again. By storing the roller assembly 32, the convenience of movement and the stability of support of the present invention can be guaranteed, thereby increasing the overall practicality.

[0036] The present invention can change the distance between the pressing plate and the supporting plate below it by arranging a pressing plate that can slide up and down inside the motion frame, so that fruit and vegetable slices of different thicknesses can be placed on the supporting plate, thereby expanding the scope of application of the present invention and controlling the quick freezing effect of the fruit and vegetable slices. Through the movement of the two sets of sliding plates, the support swing rod on the upper end of the sliding plate can be pushed to rotate, thereby pushing the box body to move up, changing the height of the present invention, and improving the applicability of the present invention. Through the engagement of the limit block and the limit groove, the limit block supports the position of the sliding plate, thereby ensuring the stability of the height adjustment of the present invention, and reducing the wear between the driving rod and the sliding plate. Through the lifting rod following the upward movement of the box body, the roller assembly is stored in the interior of the base, so that the base contacts the ground, ensuring the stability of the support of the present invention. At the same time, the convenience of movement of the present invention can be ensured by the roller assembly. By controlling the engagement between the engaging piece and the engaging groove, the positional relationship between the lifting rod and the docking block is controlled, which is convenient for controlling the position of the roller assembly.
