It also has good rehydration properties and contains no additives, making it an ideal natural and hygienic food.
[0003] Utility model patent application number 202420061503.9 discloses a quantitative weighing device for freeze-dried fruit processing. The device uses hoppers fixed to both sides of a rotating roller, allowing a pressure switch to detect the pressure inside the hopper after receiving the dried fruit, thus monitoring the weight of the dried fruit. However, the uniformly prepared freeze-dried fruit varies in size, resulting in different fruit pulp sizes within packages of the same weight, affecting sales. Therefore, it is necessary to develop a quantitative weighing device for freeze-dried fruit processing to address the shortcomings of the existing technology. Utility Model Content

[0027] 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.
[0028] like Figures 1 to 6 As shown, this utility model provides a quantitative weighing device for freeze-dried fruit processing, including several main units 1. A quantitative plate 9 is provided on the top of the main unit 1, and a feeding rack 3 is provided above the quantitative plate 9. A buffer component 2 located above the quantitative plate 9 is connected to the bottom of the feeding rack 3. A screening component 4 located above the buffer component 2 is provided inside the feeding rack 3. A feeding conveyor belt 6 is passed through the inside of the screening component 4. Protective frames 5 are fixedly connected to both sides of the feeding rack 3. The feeding conveyor belt 6 is attached to the bottom of the inner cavity of the protective frame 5.
[0029] The feeding conveyor belt 6 passes over the feeding racks 3 above several main units 1 and through their respective screening components 4. One end of the feeding conveyor belt 6 extends into the hopper, and the other end passes over several main units 1 and the feeding racks 3 above them in sequence. The filter holes of the screening components 4 above the main units 1 located in the bottom area of the feeding conveyor belt 6 are different. The filter holes in the screening components 4 closer to the hopper are larger than those in the screening components 4 farther away from the hopper. Due to the setting of the screening components 4, with the cooperation of the feeding racks 3 and the protective frame 5, the freeze-dried fruit conveyed on the feeding conveyor belt 6 can be screened, so that freeze-dried fruit of corresponding size falls from the same screening plate 42 after passing through the buffer component 2, so that the freeze-dried fruit weighed on each quantitative pan 9 is similar in size, thereby ensuring that the packaged freeze-dried fruit after quantitative weighing is uniform in size, which helps to improve the quality of packaging and sales.
[0030] The main unit 1 has several support frames 7 fixedly installed on its top. The front of the main unit 1 has an operation panel 8 embedded in it. The upper end of the operation panel 8 extends to the top of the main unit 1 and is connected to the metering plate 9. The metering plate 9 is located between the support frames 7.
[0031] The host 1 is equipped with a transfer component 10, the upper layer of which is located inside the support frame 7 and above the weighing mechanism inside the host 1.
[0032] The transfer assembly 10 consists of a transfer belt 101 and an adapter groove 102. The two ends of the transfer belt 101 are connected to a transfer motor via a transmission roller. The transfer belt 101 is adapted to the main unit 1 and the support frame 7. The upper layer of the transfer belt 101 is located above the weighing mechanism. The adapter groove 102 is opened on the transfer belt 101. The lower end of the quantitative disk 9 is embedded into the adapter groove 102 from top to bottom. The outer diameter of the upper end of the quantitative disk 9 is larger than the inner diameter of the adapter groove 102.
[0033] The buffer assembly 2 includes a mounting frame 21 fixedly installed on the top of several support frames 7. A flow guide hood 22 is inserted into the mounting frame 21 from front to back. Magnetic blocks 24 are embedded between the rear end of the flow guide hood 22 and the contact surface of the mounting frame 21. Due to the setting of the magnetic blocks 24, the flow guide hood 22 is firmly inserted into the mounting frame 21 with the cooperation of the mounting frame 21, ensuring that the freeze-dried fruit screened in the screening assembly 4 can fall through the mounting frame 21 through the discharge pipe 23 at its bottom onto the metering tray 9.
[0034] The lower end of the flow guide 22 is connected to the material leakage pipe 23. The inner diameter of the material leakage pipe 23 is larger than the inner diameter of the filter hole in the screening component 4. The inner walls of both the flow guide 22 and the material leakage pipe 23 are smooth.
[0035] The flow guide 22 is funnel-shaped, the upper end of the material discharge pipe 23 is vertical and fixedly connected to the bottom of the flow guide 22, the lower end of the material discharge pipe 23 is inclined, and the extension line of the material discharge pipe passes through the metering plate 9.
[0036] The inner wall of the flow guide hood 22 is covered with a cushioning pad, and the inner wall of the discharge pipe 23 is smoothly connected to the inner wall of the cushioning pad inside the flow guide hood 22. The discharge pipe 23 has axial stretchability. Due to the setting of the flow guide hood 22, with the cooperation of the mounting bracket 21 and the magnetic block 24, the flow guide hood 22 can be stably placed between the screening component 4 and the metering plate 9. Then, the flow guide hood 22 and the discharge pipe 23 at its bottom can slow down the free-falling freeze-dried fruit, so that it falls slowly onto the metering plate 9, avoiding the situation where the impact force is too large when falling and damage occurs, thereby further improving the quality of packaging and sales.
[0037] The screening component 4 includes an adjustable screening belt 41 located inside the feeding frame 3 and above the mounting frame 21. The adjustable screening belt 41 has several screening plates 42 connected end to end inside. The filter apertures of the screening plates 42 in each adjustable screening belt 41 are different and change sequentially.
[0038] The adjustable screening belt 41 has two transmission rollers 43 connected to its internal transmission sleeve. The feeding conveyor belt 6 passes through the interior of the adjustable screening belt 41 and between the two transmission rollers 43, and is attached to the top of a screening plate 42 at the bottom. The two ends of the two transmission rollers 43 pass through the adjustable screening belt 41 and the feeding frame 3 and are fixedly connected to the adjusting knob 44. Due to the setting of the feeding frame 3, the adjustable screening belt 41 can be rotated by the cooperation of the adjusting knob 44 and the transmission rollers 43, so that different screening plates 42 on the adjustable screening belt 41 can move between the feeding conveyor belt 6 and the buffer assembly 2, thereby enabling the screening assembly 4 to screen freeze-dried fruits of different sizes and improve its applicability.
[0039] Working principle and usage process of this utility model:
[0040] Several main units 1 are placed side by side, and the corresponding buffer components 2 are snapped into the support frame 7 and the feeding frame 3 as needed. Then, the feeding frames 3 above the several main units 1 are connected to each other through the protective frame 5, and the feeding conveyor belt 6 passes through the several protective frames 5 and the screening components 4 and covers the guide hood 22 on the several main units 1.
[0041] Then, adjust the corresponding screening plate 42 on the screening belt 41 in each feeding rack 3 to the bottom of the feeding conveyor belt 6 as needed, so that the freeze-dried fruit being transported can fall into the guide hood 22 through the screening plate 42 and fall onto the metering plate 9 with the help of the leakage pipe 23.
[0042] Then, start the drive mechanism to drive the feeding conveyor belt 6 to carry out the stored freeze-dried fruit and transport it one by one to the top of the host machine 1. When the freeze-dried fruit of the corresponding size moves into the corresponding screening component 4, it can fall from the feeding conveyor belt 6 and through the screening plate 42 into the corresponding guide hood 22. After passing through the leakage pipe 23, it falls into the quantitative pan 9. Then, with the cooperation of the operation panel 8, the required quantitative weighing is completed. After ensuring that the freeze-dried fruit weighed in the quantitative weighing is similar in size, the packaging, labeling, and sales processes can be carried out.
[0043] With the cooperation of the host 1, the transfer motor is controlled to drive the transfer belt 101 to move continuously and intermittently, so that the upper adapter trough 102 can drive the large number of pans 9 that have completed the weighing and the freeze-dried fruit inside them to leave the weighing mechanism.
[0044] At the same time, the upper adapter slot 102 drives the new empty quantitative plate 9 to slide to the top of the weighing mechanism, and the upper end of the quantitative plate 9 is separated from the top of the transfer belt 101, so that the top of the quantitative plate 9 is placed directly on the top of the weighing mechanism, so as to continue quantitative weighing.
