As will be appreciated by those skilled in the art, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and description are to be regarded as illustrative in nature and not restrictive.

[0031] The disclosure below provides many different embodiments or examples for realizing different structures of the present invention. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are merely examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numbers and / or reference letters in different examples. Such repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present invention provides examples of various specific processes and materials, but a person of ordinary skill in the art will recognize the application of other processes and / or the use of other materials.

[0032] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0033] Example:

[0034] See also Figure 1 and Figure 2 This embodiment discloses a lifting feeding device, including a multi-section telescopic rod 10, a loading plate 20, a push rod 30, a connecting rod 40, a screw 50 and a motor 60. Specifically, the multi-section telescopic rod 10 has a telescopic end.

[0035] A loading plate 20 is provided on the telescopic end of the multi-section telescopic rod 10 . One end of the loading plate 20 is connected to the multi-section telescopic rod 10 . The length direction of the loading plate 20 is perpendicular to the length direction of the multi-section telescopic rod 10 .

[0036] A slide groove is provided on both sides of the carrier plate 20 , and the length direction of the slide groove is parallel to the length direction of the carrier plate 20 .

[0037] A push rod 30 is slidably mounted in each of the two chutes, with the length of each push rod 30 being parallel to the length of the multi-section telescopic rod 10. One end of each push rod 30 is located below the loading plate 20, forming the bottom end of the loading plate 20. The bottom end of each push rod 30 is fixedly connected to one end of a connecting rod 40, with the two push rods 30 being fixedly connected to both ends of the connecting rod 40.

[0038] There is a threaded hole in the middle of the connecting rod 40, and a screw rod 50 is matched in the threaded hole. The length direction of the screw rod 50 is consistent with the length direction of the slide groove, so that the screw rod 50 can drive the connecting rod 40 and the push rod 30 to move along the length direction of the slide groove.

[0039] The motor 60 is fixedly mounted on the carrier plate 20 and is located on the bottom surface of the carrier plate 20. The output shaft of the motor 60 is coaxially connected to one end of the screw 50. The end of the screw 50 away from the motor 60 is rotatably connected to a support base, and the support base is rotatably connected to the bottom surface of the carrier plate 20.

[0040] In this embodiment, the multi-section telescopic rod 10 is generally fixedly arranged on the side of the freeze dryer feed port, and then the movement of the multi-section telescopic rod 10 is controlled by an electric switch. The multi-section telescopic rod 10 can be a pneumatic mechanism.

[0041] During operation, the loading plate 20 is first mounted on the multi-section telescopic rod 10, and a tray containing vials is placed on the loading plate 20. The multi-section telescopic rod 10 then drives the loading plate 20 through the freeze dryer's feed port and into the freeze dryer. Inside the freeze dryer, when the loading plate 20 moves to the side of the shelf inside the freeze dryer, the motor 60 drives the screw 50 to rotate. The rotation of the screw 50 drives the connecting rod 40 and the two push rods 30, which push the tray onto the shelf. The motor 60 then drives the push rods 30 to retract, and the multi-section telescopic rod 10 also retracts.

[0042] Repeat the above steps several times to place all the trays on the multi-layer racks in the freeze dryer.

[0043] Through this technical solution, workers can place the material tray in the freeze dryer more easily, and the entire operation has relatively low requirements on the workers.

[0044] Preferably, in order to reduce the weight of the loading plate 20 , the middle portion of the loading plate 20 is configured as a hollow structure.

[0045] In one specific embodiment:

[0046] A support rod 70 is provided at the top end of the push rod 30 , and the length direction of the support rod 70 is consistent with the length direction of the slide groove, so that the push rod 30 and the support rod 70 form an L-shaped structure.

[0047] A pull rod 80 is provided on one end of the support rod 70 away from the push rod 30 , and the pull rod 80 can also form an L-shaped structure with the support rod 70 .

[0048] In this embodiment, by providing a support rod 70 and a pull rod 80, after the freeze dryer is completed and all medicine bottles are dried, the loading plate 20 is sent to the side of the shelf in the freeze dryer through the multi-section telescopic rod 10, and then the screw 50 is driven to rotate by the motor 60, and under the action of the motor 60, the screw 50, the connecting rod 40 and the push rod 30, the support rod 70 and the pull rod 80 are driven to move above the material tray, and the pull rod 80 is hooked on the side of the material tray away from the loading plate 20, so that the motor 60, the screw 50 and the connecting rod 40 drive the push rod 30, the support rod 70 and the pull rod 80 to return, thereby pulling the material tray back onto the loading plate 20 again, and finally the multi-section telescopic rod 10 drives the loading plate 20 out of the feed port of the freeze dryer.

[0049] In another specific embodiment:

[0050] The pull rod 80 is rotatably connected to the ends of the support rod 70. Specifically, the middle portion of the pull rod 80 is rotatably connected to the ends of the support rod 70, with one end of the pull rod 80 located above the support rod 70 and the other end located below the support rod 70. During the rotation of the pull rod 80, the upper and lower positions of the two ends of the pull rod 80 relative to the support rod 70 remain unchanged.

[0051] The pull rod 80 has a strip groove on one end located above the support rod 70 , and the length direction of the strip groove is consistent with the length direction of the pull rod 80 .

[0052] The output end of the linear motor 90 is slidably connected to the strip groove of the pull rod 80. When the output end of the linear motor 90 is fully extended, the bottom end of the pull rod 80 is close to the loading plate 20. When the output end of the linear motor 90 is fully retracted, the angle between the pull rod 80 and the support rod 70 is greater than 170 degrees.

[0053] In this embodiment, the pull rod 80 is driven to rotate by the linear motor 90, so that when the material tray is delivered to the shelf in the freeze dryer, the pull rod 80 can be prevented from hindering the movement of the material tray.

[0054] The above embodiments merely represent specific implementation methods of the present invention. Although the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art may make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements are all within the scope of protection of the present invention.
