Description

Technical Field

[0001] This utility model relates to the field of feeder technology for freeze-drying lines, and more specifically, to a feeder mechanism for large-scale freeze-drying lines. Background Technology

[0002] A freeze-drying line is a production line or equipment used in the pharmaceutical industry for the freeze-drying (lyophilization) process. A freeze-drying line typically includes a series of equipment and process steps for freezing liquid drugs or other substances and removing moisture at low temperatures, ultimately transforming them into a dry solid form.

[0003] Utility model patent CN218538069U discloses an automatic feeding mechanism for large-scale freeze-drying lines. The mechanism includes a control system, a sterile isolator, a washing system, a first conveying system, a drying system, a second conveying system, an automatic feeding system, a freeze-drying system, and a discharging system. These systems are sequentially connected inside the sterile isolator. The freeze-drying system includes a large freeze dryer connected inside the sterile isolator, and the large freeze dryer contains freeze-drying mounting components. This utility model belongs to the field of freeze-drying production line feeding technology. Specifically, it provides an automatic feeding mechanism for large-scale freeze-drying lines that is simple to implement, easy to use, and uses a feeding cart instead of a fixed feeding mechanism. This allows for accurate placement of the parts to be freeze-dried on the upper end of the freeze-drying rack, resulting in convenient and stable feeding and improved equipment applicability.

[0004] Regarding the above solution: The reference document states that the rotation of the feeding drive shaft drives the feeding drive roller to rotate together, and the feeding drive roller drives the feeding transmission belt to transmit the material inside the feeding placement seat smoothly. After transmitting a certain distance, the feeding function can be successfully achieved. However, the tilt angle of the feeding transmission belt is inconvenient to adjust. This means that when transmitting large materials, the materials may shake, tip over, or roll due to the low height of the feeding placement seat. As a result, the stability of the feeding placement seat is not high enough when transmitting and feeding materials. Utility Model Content

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a feeding mechanism for large-scale freeze-drying lines. It can effectively solve the problem that the inconvenience of adjusting the tilt angle of the feeding conveyor belt makes it difficult to adjust. This causes the material to shake, tip over, or roll when transporting large materials because the height of the feeding placement seat is too low, resulting in insufficient stability of the feeding placement seat when transporting and feeding materials.

[0006] To solve the above problems, the present invention adopts the following technical solution:

[0007] A feeding mechanism for a large freeze-drying line includes a mounting base 1, a drive roller 21 rotatably connected inside the mounting base 1, a conveyor belt 22 wrapped around the outer side of the drive roller 21, and a feeding placement seat 23 fixedly connected to the surface of the conveyor belt 22; a first servo motor 24 is mounted on the side of the mounting base 1, the first servo motor 24 is connected to the drive roller 21 to drive the drive roller 21 to rotate; a base plate 101 and an electric telescopic rod 102 are provided below the mounting base 1, a support plate 3 is fixedly connected to the top of the electric telescopic rod 102, and an adjustment mechanism 4 is provided between the mounting base 1 and the support plate 3.

[0008] Compared with existing technologies, the advantages of this utility model are:

[0009] 1. In this device, the second servo motor drives the screw to rotate smoothly. The rotation of the screw drives the moving block to move. When the moving block moves, it can smoothly drive the connecting block and the mounting base to rotate around the center of the rotating shaft through the connection between the connecting plate and the connecting block. This realizes the angle adjustment of the mounting base and the conveyor belt, reducing the possibility of large materials falling or rolling down due to the large tilt angle of the conveyor belt.

[0010] 2. In this device, the slider is limited by the reinforcing plate, which increases the stability of the slider when it moves. The connection between the slider and the slide groove also limits the movement of the moving block, thus increasing the stability of the moving block when it moves. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0018] Example:

[0019] Please see Figure 1-4 A feeding mechanism for a large freeze-drying line includes a mounting base 1. A transmission roller 21 is rotatably connected inside the mounting base 1. A conveyor belt 22 is wound around the outside of the transmission roller 21, and a feeding placement seat 23 is fixedly connected to the surface of the conveyor belt 22. A first servo motor 24 is mounted on the side of the mounting base 1 and is connected to the transmission roller 21 to drive the transmission roller 21 to rotate. A base plate 101 and an electric telescopic rod 102 are provided below the mounting base 1. A support plate 3 is fixedly connected to the top of the electric telescopic rod 102. An adjustment mechanism 4 is provided between the mounting base 1 and the support plate 3. The adjustment mechanism 4 is provided on the lower side of the mounting base 1. The base plate 101 can mount the electric telescopic rod 102, and while the electric telescopic rod 102 is connected to the support plate 3, it can also drive the support plate 3 to move up and down to adjust the height of the support plate 3.

[0020] Specifically, the adjustment mechanism 4 includes a fixed plate 47 installed on one side of the support plate 3, the top of the fixed plate 47 being connected to the bottom of the mounting base 1 via a rotating shaft 48; the surface of the support plate 3 is also provided with two bearing seats 41, a screw 42 is rotatably installed between the two bearing seats 41, a moving block 43 is threadedly connected to the outer side of the screw 42 and the moving block 43 is slidably connected to the surface of the support plate 3; a connecting block 45 is fixedly connected to the bottom of the mounting base 1, a connecting plate 44 is provided between the moving block 43 and the connecting block 45, and the two ends of the connecting plate 44 are respectively hinged to the moving block 43 and the connecting block 45; a second servo motor 46 is installed on the bearing seat 41, the second servo motor 46 is connected to the end of the screw 42 and drives the screw 42 to rotate.

[0021] Mounting base 1 can install connecting block 45. Support plate 3 can connect screw 42 through bearing seat 41, so that screw 42 can rotate smoothly. Screw 42 can connect to moving block 43 and limit the moving block 43. This allows screw 42 to drive moving block 43 to move smoothly when rotating. When moving, moving block 43 can be connected to moving block 43 and connecting block 45 through connecting plate 44, so that mounting base 1 can rotate around the center of rotating shaft 48, thereby adjusting the tilt angle of mounting base 1. When conveying larger materials, mounting base 1 can reduce the tilt angle, thereby reducing the tilting and rolling of materials. A second servo motor 46 is fixedly connected to one side of the bearing housing 41. The output shaft of the second servo motor 46 passes through the bearing housing 41. The output shaft of the second servo motor 46 is fixedly connected to one end of the screw 42 through a coupling. The second servo motor 46 can drive the screw 42 to rotate during operation, so that when the operator needs to rotate the screw 42, it is convenient and simple enough.

[0022] The upper side of the support plate 3 is provided with a sliding groove 71, and the lower side of the movable block 43 is fixedly connected to a slider 72, which is slidably embedded in the sliding groove 71. The movable block 43 can install and fix the slider 72, and when the slider 72 slides inside the sliding groove 71, the support plate 3 can limit the movement of the movable block 43 through the connection between the sliding groove 71 and the slider 72, so that the movable block 43 can be more stable and less prone to shaking when moving.

[0023] The support plate 3 is fixedly connected to the reinforcing plate 8 on the inner side of the slide groove 71, and the slider 72 is slidably connected to the outer side of the reinforcing plate 8. The support plate 3 can install and fix the reinforcing plate 8 through the slide groove 71, while the reinforcing plate 8 can limit the slider 72, so that the slider 72 can increase the stability of the movement of the moving block 43, while the slider 72 itself has high stability and is not easy to wobble.

[0024] A bearing 6 is provided between the bearing housing 41 and the screw 42. The bearing 6, through its connection with the bearing housing 41, can reinforce the screw 42 to a certain extent, making it less likely for the screw 42 to wobble or tilt during rotation.

[0025] A second reinforcing block 92 is fixedly connected to one side of the mounting base 1, and the second reinforcing block 92 is fixedly connected to the outside of the first servo motor 24. A first reinforcing block 91 is fixedly connected to one side of the bearing seat 41, and the first reinforcing block 91 is fixedly connected to the outside of the second servo motor 46. The second reinforcing block 92 can reinforce the first servo motor 24 through its connection with the mounting base 1, making the first servo motor 24 sufficiently stable during use. The first reinforcing block 91 has a similar function to the second reinforcing block 92, which can increase the stability of the second servo motor 46 during use, making the second servo motor 46 less prone to shaking or tilting.

[0026] A support plate 5 is fixedly connected to the upper side of the support plate 3. The support plate 5 is located on the side of the mounting base 1 away from the fixed plate 47. The support plate 5 can provide a certain degree of support for the mounting base 1, making it less prone to wobbling when the mounting base 1 is in a horizontal state, thus increasing the stability of the mounting base 1 during use.

[0027] The working principle and usage process of this utility model are as follows: Before use, the operator can adjust the tilt angle of the mounting base 1 and the conveyor belt 22 according to the size of the material to reduce the possibility of the material falling over due to the large tilt angle of the conveyor belt 22. During adjustment, the operator can start the second servo motor 46. When the second servo motor 46 is running, it will drive the screw 42 to rotate. The rotation of the screw 42 can smoothly drive the moving block 43 to move. When the moving block 43 moves, it will push the connecting block 45 and the mounting base 1 through the connecting plate 44. Through the connection between the mounting base 1 and the connecting block 45, the angle of the mounting base 1 and the conveyor belt 22 will be raised. When the moving block 43 moves to the other side, it can pull the connecting block 45 and the mounting base 1 through the connecting plate 44. And through the connection between the rotating shaft 48 and the mounting base 1, it will drive the mounting base 1 to rotate and move downward, thereby reducing the tilt angle of the mounting base 1. At the same time, when the electric telescopic rod 102 is extended and retracted, the height of the mounting base 1 can be smoothly adjusted.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
