[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Based on the embodiments in this application, other similar embodiments obtained by those skilled in the art without creative effort should all fall within the scope of protection of this application. Furthermore, directional terms mentioned in the following embodiments, such as "up," "down," "left," and "right," are only for reference to the directions in the accompanying drawings; therefore, the directional terms used are for illustrative purposes and not for limiting the invention.

[0026] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0027] According to an embodiment of this utility model, a door opening device for a lifting system transfer compartment is provided. Please refer to [link / reference]. Figures 1 to 4 The system includes: a first spring 4, the two ends of which are connected to the door 3 of the transfer chamber 2 and the wall of the transfer chamber 2, respectively, and the door 3 is hinged to the discharge end of the transfer chamber 2; a guide plate 6, which is located on one side of the door 3 and has guide surfaces that are inclined along the opening and closing directions of the door 3; and a first roller 7, which is connected to the side of the door 3 near the guide plate 6. When the first roller 7 is not in contact with the guide surface, the first roller 7 moves along the extension line of the length direction of the guide plate 6, and the door 3 is locked under the action of the first spring 4. When the first roller 7 is in contact with the guide surface, the wheel surface of the first roller 7 always rolls along the guide surface to open or close the door 3.

[0028] It should be noted that the first spring 4, guide plate 6, and first roller 7 work together. When the first roller 7 is not in contact with the guide surface, the door 3 is locked under the action of the first spring 4. When the first roller 7 moves to the guide plate 6, the first roller 7 is in contact with the guide surface. The first roller 7 first passes through the guide surface inclined along the opening direction of the door 3, and the first spring 4 is stretched, causing the door 3 to open. The first roller 7 then passes through the guide surface inclined along the closing direction of the door 3, and with the restoring force of the first spring 4, the door 4 is closed. This realizes that the door 3 of the transmission compartment 2 automatically opens and closes when it passes through the door opening device. The structure is simple, and the opening and closing of the door 3 can be realized without connecting power and signal cables to the transmission compartment 2, thus reducing costs.

[0029] For some specific embodiments, please refer to Figure 3 The bottom plate of the transfer chamber 2 is inclined, with the end near the door 3 being lower than the end away from the door 3, so that the goods 21 transported by the transfer chamber 2 slide out under the action of gravity after the door 3 is opened, and the discharge is completed automatically.

[0030] In the lifting system's transmission chamber 2 opening device of this embodiment, the guide surface includes a first guide surface 61, a second guide surface 62, and a third guide surface 63 connected sequentially along the movement direction of the transmission chamber 2. The first guide surface 61 is inclined towards the opening direction of the chamber door 3, the second guide surface 62 is parallel to the movement direction of the transmission chamber 2, and the third guide surface 63 is inclined towards the closing direction of the chamber door 3. When the first roller 7 passes the first guide surface 61, the chamber door 3 gradually opens, and the first spring 4 is stretched. When the first roller 7 passes the second guide surface 62, the chamber door 3 remains open. When the first roller 7 passes the third guide surface 63, under the restoring force of the first spring 4, the chamber door 3 gradually closes. The opening of the chamber door 3 is achieved through the height difference between the first guide surface 61 and the second guide surface 62, and the closing of the chamber door 3 is achieved through the height difference between the second guide surface 62 and the third guide surface 63, and with the help of the elastic restoring force of the first spring 4.

[0031] The lifting system transfer chamber 2 opening device in this embodiment also includes a telescopic mechanism 8, which is fixed on the frame 1 and connected to the guide plate 6 to move the guide plate 6 away from or closer to the transfer chamber 2.

[0032] It should be noted that when the telescopic mechanism 8 moves the guide plate 6 closer to the transfer chamber 2, the guide plate 6 is located on the extension line of the movement trajectory of the first roller 7. When the telescopic mechanism 8 moves the guide plate 6 away from the transfer chamber 2, please refer to [the relevant documentation]. Figure 4 The guide plate 6 is offset from the extension line of the movement trajectory of the first roller 7 so that the transfer chamber 2 passes through the area of ​​the guide plate 6 with the door 3 closed, thus preventing the guide plate 6 from interfering with the first roller 7.

[0033] Specifically, the lifting system can be equipped with multiple guide plates 6, and the telescopic mechanism 8 is set one-to-one with the guide plates 6, so that multiple transfer chambers 2 can open the chamber door 3 at multiple guide plates 6 respectively, realizing multi-destination lifting and transportation of liquid transport bags.

[0034] In some alternative embodiments, the movement of the guide plate 6 relative to the transfer chamber 2 can be achieved by a telescopic mechanism such as a cylinder or an electric cylinder.

[0035] In the lifting system transfer chamber 2 opening device of this embodiment, the telescopic mechanism 8 includes: a cam 81, the wheel surface of the cam 81 abuts against the guide plate 6, the cam 81 rotates to push the guide plate 6 to move away from or towards the transfer chamber 2; a guide unit, the guide unit is connected to the guide plate 6, the guide unit guides the movement direction of the guide plate 6; and a drive motor 82, the output end of the drive motor 82 is connected to the cam 81 to drive the cam 81 to rotate.

[0036] It should be noted that the drive motor 82 drives the cam 81 to rotate, and the guide plate 6 moves by means of the change in diameter of the cam 81. In addition, by setting a guide unit, the movement direction of the guide plate 6 is guided to prevent the guide plate 6 from deviating from the extension line of the movement trajectory of the first roller 7 when the telescopic mechanism 8 drives the guide plate 6 to approach the transmission chamber 2.

[0037] In the lifting system transfer chamber 2 door opening device of this embodiment, the guide unit includes: a guide rod 83, which is connected to the side of the guide plate 6 away from the transfer chamber 2, and a limiting part 831 is provided at the end of the guide rod 83 away from the guide plate 6; a guide sleeve 84, which is fixed on the frame 1, and the guide rod 83 is movably inserted inside the guide sleeve 84; and a second spring 85, which is sleeved on the periphery of the guide sleeve 84, and the two ends of the second spring 85 are respectively connected to the guide sleeve 84 and the limiting part 831.

[0038] It should be noted that when the cam 81 rotates, it drives the guide plate 6 to approach the transmission chamber 2. The guide rod 83 moves with the guide plate 6. Under the limiting action of the limiting part 831 and the guide sleeve 84, the second spring 85 is compressed. When the cam 81 continues to rotate, the clamping force received by the second spring 85 gradually decreases. Under the restoring force of the second spring 85, the guide plate 6 gradually returns to its original position.

[0039] In the lifting system transfer chamber 2 door opening device of this embodiment, there are multiple guide units, which are arranged at intervals along the length of the guide plate 6.

[0040] Specifically, there are two guide units, which are symmetrically arranged on the guide plate 6 and are respectively close to the two ends of the guide plate 6, thereby providing a stable guiding effect for the movement of the guide plate 6.

[0041] In the lifting system transfer chamber 2 opening device of this embodiment, the guide plate 6 is provided with a connecting seat 9 on the side near the cam 81, and a second roller 91 is provided on the connecting seat 9. The wheel surface of the cam 81 abuts against the wheel surface of the second roller 91 to push the guide plate 6 to move away from or towards the transfer chamber 2.

[0042] It should be noted that by setting the connecting seat 9, the rotation of the cam 81 is prevented from causing wear on the guide plate 6. At the same time, the cam 81 cooperates with the second roller 91 to realize the movement of the guide plate 6. The frictional resistance between the cam 81 and the second roller 91 is small, and the wear on the cam 81 is also relatively small.

[0043] In the lifting system transfer chamber 2 door opening device of this embodiment, the telescopic mechanism 8 is fixed on the mounting base 10, and the mounting base 10 is detachably connected to the frame 1 to facilitate the maintenance and replacement of the telescopic mechanism 8.

[0044] In the lifting system transfer chamber 2 opening device of this embodiment, the guide plate 6 is provided with base plates 5 at both ends. The base plates 5 are integrally connected with the guide plate 6. The ends of the two base plates 5 that are far apart are provided with rounded corners so that the first roller 7 can roll smoothly to the guide surface and reduce the wear of the first roller 7.

[0045] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made in accordance with the scope of this application should still fall within the scope of the present invention.
