[0002] With the improvement of people's living standards and the enhancement of health awareness, the requirements for quality and safety in food, medicine, biological products and other fields are becoming higher and higher. Freeze-drying technology has gradually occupied an important position in the market due to its unique advantages.

[0003] When placing items that need to be freeze-dried into the freeze-drying rack, a feeding device is required. However, the existing quantitative feeding device for freeze dryers still has some shortcomings in actual use:

[0004] After the freeze-dried items are placed in the tray, workers push the tray into the freeze dryer one by one. Not only is the loading speed slow, but if the workers are not careful during the transportation and the tray shakes, the items inside the tray will also shake. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings in the prior art that workers load materials one by one, which is not only slow in loading speed, but also causes shaking of the items inside the tray if the workers are not careful during the transportation process, and thus a quantitative feeding device for a freeze dryer is proposed.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A quantitative feeding device for a freeze dryer comprises a freeze dryer body and a support frame, wherein four moving wheels are fixedly mounted on the bottom of the support frame for moving the support frame, a plurality of brackets are arranged in sequence from top to bottom, a mountain-shaped frame is fixedly connected to one side of the plurality of brackets, two push plates are slidably connected to the tops of the plurality of brackets, a base is slidably connected to the tops of the plurality of brackets, and the base is located between the two push plates, a flip plate is provided above the base, a tray is placed on the tops of the plurality of brackets, and the two push plates cooperate with the flip plate and the tray.

[0008] In one possible design, a rotating shaft is fixedly connected to the base, and the rotating shaft rotates through the flip plate. Torsion springs are fixedly connected to both sides of the flip plate, and the two torsion springs are both sleeved on the outer wall of the rotating shaft and fixedly connected to the base.

[0009] In a possible design, a matching groove is provided at the bottom of one end of the tray, and the flip plate matches the matching groove.

[0010] In a possible design, three screw rods are rotatably connected in the bracket, the three screw rods are arranged at equal intervals, and all three screw rods pass through the bracket and extend into the mountain-entering frame, and the base and two push plates are respectively threadedly sleeved on the outer walls of the corresponding screw rods, one end of the screw rods on both sides is fixedly sleeved with a sprocket, and one end of the screw rod in the middle is fixedly sleeved with a double-row sprocket, and the two sprockets and the double-row sprocket are connected by chain transmission.

[0011] In a possible design, three connecting rods are rotatably connected in the mountain-shaped frame, and the outer walls of the three connecting rods are fixedly sleeved with multiple first bevel gears. The outer walls of the multiple screw rods in the multiple brackets are fixedly sleeved with second bevel gears, and the second bevel gears are meshed with the first bevel gears respectively. A second drive motor is fixedly installed on one side of the mountain-shaped frame, and the output shaft of the second drive motor extends into the mountain-shaped frame and is fixedly connected to one end of the output shaft of one of the screw rods.

[0012] In one possible design, two sliding blocks are fixedly connected to both sides of the multiple brackets, and the sliding blocks slide correspondingly in the support frame, two threaded columns are rotatably connected in the support frame, nuts are fixedly connected to both sides of the brackets, and the two threaded columns have corresponding threads passing through the nuts, two first drive motors are fixedly installed on the top of the support frame, and the output shafts of the two first drive motors are fixedly connected to the top of the threaded columns.

[0013] In the present application, according to the required freeze-dried amount, the freeze-dried items are placed on a tray and placed one by one on multiple brackets. The device is moved to the freeze dryer loading position through the four moving wheels at the bottom of the support frame, and the two first drive motors are started. The output shafts of the two first drive motors respectively drive the two threaded columns to rotate, thereby uniformly adjusting the heights of the multiple brackets. The second drive motor is started, and one of the lead screws is driven to rotate by the output shaft of the second drive motor. The two sprockets and the double-row sprockets are connected by a chain drive, thereby driving the three lead screws to rotate synchronously. Each bracket is driven by three connecting rods, and the second bevel gear at one end of each lead screw is connected by a chain drive. The first bevel gear corresponding to the outer wall of the connecting rod is engaged with each other, so that the screw in each bracket rotates synchronously, and the three screws on each chain drive the two push plates and the flip plate to move. The multiple trays are pushed synchronously by the push plates to achieve synchronous quantitative loading. When unloading, because one side of the flip plate is provided with an arc, the flip plate and one end of the tray form a conflict, forming a flip, sliding into the matching groove, and the flip plate is reversed by the torsion spring. The second drive motor rotates in the opposite direction, and the output shaft of the second drive motor drives the screw to rotate in the opposite direction, and then the flip plate is pulled in the matching groove to pull the freeze-dried tray out of the freeze dryer.

[0014] Beneficial effects: In the utility model, the quantitative feeding device for a freeze dryer can achieve unified adjustment of the heights of multiple storage units through two driving devices, a first driving motor and corresponding threaded columns and nuts, ensuring that each storage unit is at the same horizontal position during the feeding process, further improving the accuracy of feeding;

[0016] In the utility model, the arc-shaped design of the flip plate and the interference with the tray realize automatic folding and unloading of freeze-dried items without manual intervention, thereby improving the efficiency and convenience of unloading.

[0017] The utility model has the beneficial effects of precise quantification, efficient movement and adjustment, intelligent transmission and synchronization, and convenient unloading, and can significantly improve the production efficiency and product quality of the freeze dryer.
