Description

Technical Field

[0001] The utility model relates to the technical field of weight checking equipment, in particular to a quantitative automatic weight checking equipment for freeze-dried fruits and vegetables. Background Art

[0002] The main function of the quantitative automatic checkweighing equipment for freeze-dried fruits and vegetables is to quantitatively weigh, inspect and grade the processed freeze-dried fruits and vegetables. This type of equipment is widely used in the food processing industry, especially in the production of freeze-dried (freeze-dried) fruits and vegetables.

[0003] Currently, most existing fruit and vegetable freeze-dried weighing equipment uses dynamic sensors for weighing. When weighing a large number of fruits and vegetables at one time, a baffle must be installed outside the weighing pan to prevent the fruit and vegetable products from slipping or shifting during the weighing process, resulting in inaccurate weighing or affecting the smooth operation of the production line. After the freeze-drying process, the moisture of fruits and vegetables is almost completely removed, making them prone to absorbing foreign substances or sticking to each other. When these substances come into contact with the baffle, they are easily attached to the baffle surface, affecting the subsequent weighing results. Therefore, it is necessary to redesign a quantitative automatic weighing equipment for fruit and vegetable freeze-dried production to address the above problems. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a quantitative automatic weight checking device for freeze-dried fruits and vegetables.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Reference Figure 1-4A quantitative automatic checkweighing device for freeze-dried fruits and vegetables comprises a weighing platform 1, two sets of transmission rollers are rotatably connected to the weighing platform 1, the two sets of transmission rollers are connected to each other by a transmission belt 2, an outer frame 4 is fixedly connected to the upper end of the weighing platform 1, a baffle 5 is fixedly connected to the inner wall of the outer frame 4, a weighing plate 8 is rotatably connected to the baffle 5, a checkweighing sensor is provided in the weighing plate 8, a rack 11 is slidably connected to the outer wall of the baffle 5, a scraper 9 is fixedly connected to the rack 11, the scraper 9 is in contact with the inner wall of the baffle 5, and a driving mechanism for driving the rack 11 to rotate is installed on the outer wall of the baffle 5;

[0022] During the weighing process, the freeze-dried fruits and vegetables are placed on the upper end surface of the weighing plate 8 and are weighed with the help of the weighing sensor inside the weighing plate. After the weighing process is completed, the weighing plate 8 is flipped over to allow the freeze-dried fruits and vegetables on it to slide to the upper end surface of the transmission belt 2 for the next step. During this process, the scraper 9 slides synchronously to scrape off the freeze-dried fruits and vegetables attached to the inner wall of the baffle 5. It should be noted that when the freeze-dried fruits and vegetables are placed on the weighing plate 8, they will not immediately adhere to the outer wall of the baffle 5 in a short period of time.

[0023] The driving mechanism includes a gear 2 13 rotatably connected to the side wall of the baffle 5, the gear 2 13 is meshed with the rack 11, the side wall of the weighing platform 1 is fixedly connected to a fixed plate 10, the upper end of the fixed plate 10 is fixedly connected to a limit rod 12, the rack 11 is slidably connected to the outer wall of the limit rod 12, the outer wall of the baffle 5 is rotatably connected to a gear 14, the gear 14 and the gear 2 13 are meshed with each other, the gear 14 is coaxially fixedly connected to the weighing plate 8, the side wall of the baffle 5 is fixedly connected to the side plate 6, the outer wall of the side plate 6 is L-shaped, the outer walls of the weighing platform 1 and the side plate 6 are respectively installed with a motor 1 3 and a motor 2 7, the motor 1 3 and the motor 2 7 are coaxially fixedly connected to the transmission roller and the gear 14; when the weighing plate 8 flips over, the scraper 9 slides from top to bottom to avoid conflict with the weighing plate 8. If the upper end of the weighing plate 8 is attached, it can automatically detach from the plate surface under its own gravity after flipping.

[0024] In the present utility model, the device is specifically used as follows: when the production line starts running, the freeze-dried fruit and vegetable products are conveyed to the weighing plate 8 of the equipment, and the weighing sensor of the weighing plate 8 detects the weight of the product in real time. After the weighing sensor completes weighing, the motor 2 7 is started, driving the gear 1 14 coaxially connected to the weighing plate 8 to rotate, and the gear 1 14 is engaged with the gear 2 13, driving the rack 11 to move synchronously. As the rack 11 slides, the scraper 9 starts to slide from top to bottom to ensure that there is no conflict with the weighing plate 8. During the flipping process of the weighing plate 8, under the action of gravity, the freeze-dried fruit and vegetable products naturally slide onto the transmission belt 2.

[0025] While the weighing plate 8 flips and the product slides down, the rack 11 continues to drive the scraper 9 to slide up and down, cleaning the residues of the freeze-dried fruits and vegetables adhering to the inner wall of the baffle 5, ensuring that the inner wall of the baffle 5 will not affect the subsequent production process due to the residual product, while also reducing material waste.

[0026] The freeze-dried fruit and vegetable products that slide onto the conveyor belt 2 enter the next step of the production line as the conveyor belt 2 moves, such as packaging, encapsulation or further processing.

[0027] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
