Description

Technical Field

[0001] This utility model relates to the technical field of dehydrated fruit and vegetable screening devices, specifically a dehydrated fruit and vegetable particle vibration screening device. Background Technology

[0002] Dehydrated fruit and vegetable pellets are dried, granular products made by dehydrating fresh fruits and vegetables. This processing method retains the nutrients, flavor, and color of the fruits and vegetables while removing most of the moisture, making them easier to store, transport, and consume. A vibrating screening device for dehydrated fruit and vegetable pellets is a device specifically designed for grading, removing impurities, or screening dehydrated fruit and vegetable pellets. It typically uses vibration principles to separate the pellets according to size, shape, or density.

[0003] Existing vibrating screens mostly use fixed screens. However, the size, shape, and density of different dehydrated fruit and vegetable particles vary greatly. The aperture of the fixed screen cannot be flexibly adjusted, making it difficult to adapt to the screening needs of different materials. This leads to a decrease in screening accuracy and a lower yield of qualified products. Therefore, it is necessary to provide a vibrating screening device that allows for quick assembly and disassembly of the screen to improve the adaptability of screening. Utility Model Content

[0004] The purpose of this utility model is to provide a vibrating screening device for de-fruiting and vegetable granules, so as to solve the problems mentioned in the background art. To solve the above technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model is a vibrating screening device for de-fruiting and vegetable granules, comprising:

[0006] The mounting frame and the screen are arranged inside the mounting frame.

[0007] The mounting assembly includes a fixed frame, a circular hole, a movable hole, and a movable column. The fixed frame is U-shaped, and there are two fixed frames, which are fixed on the inner sides of the mounting frame respectively. The fixed frame is located below the screen. The circular hole is opened on the lower surface of the fixed frame, and the movable hole is opened on the upper surface of the fixed frame. The circular hole and the movable hole are directly opposite each other. The movable column slides through the circular hole and the movable hole.

[0008] Furthermore, a bracket is elastically connected to the lower surface of the mounting frame, a feeding frame is welded to the end of the screen, and a vibration motor is screwed onto the outer surface of the mounting frame.

[0009] Furthermore, a baffle is fixed to the middle of the outer surface of the movable column, and the baffle is located in the middle of the fixed frame.

[0010] Furthermore, a spring is fixed to one side of the baffle, and the spring is located inside the fixed frame.

[0011] Furthermore, the screen has slots at its four corners, and the ends of the movable columns extend into the slots.

[0012] Furthermore, it also includes an evacuation assembly, which includes a mounting plate, a rotary motor, a lead screw, and a movable plate. There are two mounting plates, which are fixed on both sides of the front end of the mounting frame. The rotary motor is fixed on one side of the mounting plate.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0027] Please see Figure 1-4 As shown, this utility model is a vibrating screening device for de-fruiting and vegetable granules, comprising:

[0028] Mounting frame 11 and screen 13, screen 13 is placed inside mounting frame 11, bracket 12 is elastically connected to the lower surface of mounting frame 11, feeding frame 14 is welded to the end of screen 13, and vibration motor 15 is screwed to the outer surface of mounting frame 11.

[0029] The mounting frame 11 is used to fix the screen 13 and the feeding frame 14 and provide them with a stable installation environment. The screen 13 is used to screen materials according to their size, shape or density. The bracket 12 uses an elastic design such as springs or rubber shock-absorbing pads to buffer the impact of vibration, protect the screen 13 and the mounting frame 11, and reduce equipment noise. The feeding frame 14 ensures that the screened materials are discharged in an orderly manner.

[0030] The mounting components include a fixed frame 21, a circular hole 22, a movable hole 23, and a movable column 24. The fixed frame 21 is U-shaped, and there are two fixed frames 21, which are fixed on the inner sides of the mounting frame 11 respectively. The fixed frame 21 is located below the screen 13. The circular hole 22 is opened on the lower surface of the fixed frame 21, and the movable hole 23 is opened on the upper surface of the fixed frame 21. The circular hole 22 and the movable hole 23 are directly opposite each other. The movable column 24 slides through the interior of the circular hole 22 and the movable hole 23.

[0031] The fixed frame 21 is used to fix the screen 13 and enable its quick replacement. The circular hole 22 is used as a sliding guide for the movable column 24. The movable hole 23 is directly opposite to the circular hole 22, allowing the movable column 24 to pass through and move up and down. The movable column 24 is used to fix the screen 13, and by sliding through the circular hole 22 and the movable hole 23, the end extends into the slots 27 at the four corners of the screen 13, locking the screen 13 in the mounting frame 11.

[0032] A baffle 25 is fixed in the middle of the outer surface of the movable column 24, and the baffle 25 is located in the middle of the fixed frame 21. A spring 26 is fixed on one side of the baffle 25, and the spring 26 is located inside the fixed frame 21. The four corners of the screen 13 are provided with slots 27, and the end of the movable column 24 extends into the slots 27.

[0033] The baffle 25 is used to limit the movement range of the movable column 24 and serves as the attachment point of the spring 26. When the movable column 24 is pressed, the spring 26 is compressed; when the movable column 24 is released, the spring 26 returns to its original shape, pushes the movable column 24 to reset and lock the screen 13. The slot 27 is used to cooperate with the end of the movable column 24 to lock the screen 13.

[0034] Working principle:

[0035] When replacing the screen 13, simply press the movable column 24 downwards from above. The movable column 24 will simultaneously drive the baffle 25 to move downwards. Under the limit of the fixed frame 21, the baffle 25 will compress the spring 26. At this time, the end of the movable column 24 will exit from the slot 27. Then, pull the screen 13 out from the end of the mounting frame 11. Next, take out the new screen 13 and place it on the fixed frame 21. When the slot 27 is aligned with the movable hole 23, the spring 26 will quickly return to its original shape under the elastic force of the spring 26, driving the movable column 24 to be inserted into the slot 27. Install the screen 13 and the feeding frame 14 in the mounting frame 11. This allows for quick replacement of screens 13 with different apertures.

[0036] In this step, when replacing the screen 13, the old screen 13 can be pulled directly out from the end of the mounting frame 11, and the new screen 13 will automatically reset after being put in. The operation is simple and can achieve instant unlocking and locking, significantly shortening the replacement time and improving production efficiency.

[0037] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, further includes:

[0038] An evacuation assembly includes a mounting plate 31, a rotary motor 32, a lead screw 33, and a movable plate 34. There are two mounting plates 31, which are fixed to the front sides of the mounting frame 11 respectively. The rotary motor 32 is fixed to one side of the mounting plate 31. The lead screw 33 rotates through the inside of the two mounting plates 31, and one side of the lead screw 33 is fixed to the output end of the rotary motor 32. The movable plate 34 is threaded through the outer surface of the lead screw 33. An evacuation plate 35 is fixed to the lower surface of the movable plate 34, and limit posts 36 are fixed to both sides of the mounting plate 31. The movable plate 34 slides through the outer surface of the limit posts 36.

[0039] Mounting plate 31 serves as the support and fixed base for the evacuation assembly. Rotary motor 32 provides the power source, driving lead screw 33 to rotate, thereby causing movable plate 34 and evacuation plate 35 to perform horizontal reciprocating motion. Lead screw 33 converts the rotational motion of rotary motor 32 into linear motion, pushing movable plate 34 to move horizontally along the axis of lead screw 33. Movable plate 34 is threaded through the outer surface of lead screw 33 and moves horizontally as lead screw 33 rotates, driving evacuation plate 35 to reciprocate.

[0040] The dispersion plate 35 is in direct contact with the de-processed fruits and vegetables. Through reciprocating motion, it disperses and flattens the materials, preventing them from accumulating on the surface of the screen 13. The limiting column 36 restricts the travel range of the movable plate 34, preventing it from detaching from the screw 33 or deviating excessively.

[0041] Working principle:

[0042] When the dehydrated fruits and vegetables are vibrated and screened, the rotary motor 32 is started by the external controller. The rotary motor 32 drives the lead screw 33 to rotate. Under the rotation of the lead screw 33, the movable plate 34 is driven to move horizontally back and forth on the outer surface of the lead screw 33. Under the limit of the limit post 36, the movable plate 34 drives the dispersing plate 35 to disperse the dehydrated fruits and vegetables, so as to prevent the fruits and vegetables from piling up on the surface of the screen 13.

[0043] In this step, the reciprocating motion of the evacuation plate 35 ensures that the material is evenly distributed on the surface of the screen 13, avoiding local accumulation, improving screening efficiency, and reducing the risk of screen blockage.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
