Technical Field
[0001] This utility model relates to the field of cyclodextrin derivative production technology, specifically to a quantitative dripping device for the production of cyclodextrin derivatives. Background Technology
[0002] Cyclodextrin derivatives, compounds obtained through molecular modification of natural cyclodextrins, play a crucial role in supramolecular construction due to their unique molecular structures and cavities capable of binding substrates or guest molecules. In particular, the construction of functionalized supramolecular aggregates relies heavily on cyclodextrin derivatives. In the industrial and pharmaceutical fields, cyclodextrin derivatives are widely used. For example, hydroxypropyl and sulfonyl ether group cyclodextrin derivatives have been included in the pharmacopoeias of many countries and play an important role in pharmaceutical formulations.
[0003] The production of cyclodextrin derivatives requires the addition of materials, which involves the use of a quantitative material dispensing device. However, common quantitative material dispensing devices do not have a stirring function, which may lead to incomplete dilution and mixing of the materials stored in the storage container, thus affecting the production of cyclodextrin derivatives.

A rectangular plate is fixedly connected to the bottom of the rack. A flipping frame is fixedly connected to the bottom of the rectangular plate. A support plate is fixedly connected to the top of the storage cylinder.
[0007] Preferably, the front of the connecting box has a movable opening, and the connecting block passes through the movable opening, so that the connecting block can be moved through the movable opening.
[0008] Preferably, the rectangular block is slidably connected to the inner wall of the connecting box, and the worm gear passes through the support plate and rotates to provide stable support for the support plate.

[0010] Preferably, the water pumping pipe is fixedly connected to the bottom of the storage cylinder, and the water pumping pipe is connected to the inside of the storage cylinder, so that the material inside the storage cylinder can be pumped out through the water pumping pipe.
[0011] Preferably, the mixing mechanism includes a right-angle plate, which is fixedly connected to the top of the storage cylinder.

[0014] 1. The quantitative dripping device for producing cyclodextrin derivatives uses a stirring mechanism. When the gear is no longer engaged with the rack, the compressed spring can push the tilting frame to descend.

While achieving agitation, it also achieves stirring through transmission, further improving the quality of stirring and mixing, and facilitating the quantitative dripping of materials for producing cyclodextrin derivatives.

[0028] The stirring mechanism 6 includes a support base 61, which is fixedly connected to the outer wall of the storage cylinder 1. A motor 62 is fixedly connected to the inner side of the support base 61. A worm gear 63 is fixedly connected to the output end of the motor 62. A gear 64 is fixedly connected to the outer wall of the worm gear 63. A rack 65 meshes with the outer ring of the gear 64. A connecting block 66 is fixedly connected to the back of the rack 65. A rectangular block 67 is fixedly connected to the back of the connecting block 66. A spring 68 is fixedly connected to the top of the rectangular block 67. A connecting box 69 is fixedly connected to the top of the storage cylinder 1. A rectangular plate 602 is fixedly connected to the bottom of the rack 65. A flipping frame 603 is fixedly connected to the bottom of the rectangular plate 602. A support plate 601 is fixedly connected to the top of the storage cylinder 1.
[0029] Furthermore, the front of the connecting box 69 has a movable opening, through which the connecting block 66 passes, allowing the connecting block 66 to move.
[0030] Furthermore, the rectangular block 67 is slidably connected to the inner wall of the connecting box 69, and the worm gear 63 passes through the support plate 601 and rotates to provide stable support for the support plate 601.
[0031] Furthermore, the top of the storage cylinder 1 is provided with an opening, through which the rectangular plate 602 passes, allowing the rectangular plate 602 to move.
[0032] Furthermore, the water pumping pipe 4 is fixedly connected to the bottom of the storage cylinder 1, and the water pumping pipe 4 is connected to the inside of the storage cylinder 1, so that the material inside the storage cylinder 1 can be pumped out through the water pumping pipe 4.
[0033] Example 2
[0034] See Figures 1 to 5 Furthermore, based on Embodiment 1, the mixing mechanism 7 further includes a right-angle plate 71, which is fixedly connected to the top of the storage cylinder 1. A mixing shaft 72 is rotatably connected to the top of the storage cylinder 1, and a worm gear 73 is fixedly connected to the outer wall of the mixing shaft 72 to facilitate stirring of the material inside the storage cylinder 1.
[0035] Furthermore, the outer ring of the worm gear 73 meshes with the outer wall of the worm 63, and the mixing shaft 72 is rotatably connected to the inner side of the right-angle plate 71 to provide stable support for the right-angle plate 71.
[0036] In actual operation, when this device is used, the material for producing cyclodextrin derivatives is first put into the storage cylinder 1. Then, the motor 62 can be started. The output end of the motor 62 can drive the worm 63 to rotate. The worm 63 can drive the gear 64 to rotate. The gear 64 meshes with the rack 65 to drive the connecting block 66 to move. The connecting block 66 can drive the rectangular block 67 to move and compress the spring 68. The rack 65 can drive the flipping frame 603 to move upward through the rectangular plate 602. Since the gear 64 is irregularly arranged, when the gear 64 is no longer meshing with the rack 65, the spring 68, which is in a compressed state, can push the flipping frame 603 to descend. At this time, since the worm 63 is continuously rotating, the flipping frame 603 will move up and down reciprocally, realizing the purpose of flipping the cyclodextrin derivative material and stirring and mixing the cyclodextrin derivative material to ensure the uniformity of the dilution and mixing of the cyclodextrin derivative material.
[0037] During the rotation of the worm gear 63, the worm wheel 73 will also rotate, which in turn will drive the mixing shaft 72 to rotate. The mixing shaft 72 can stir and mix the cyclodextrin derivative material. While achieving the turning, the transmission can also achieve the purpose of stirring, further improving the quality of stirring and mixing, and facilitating the quantitative addition of materials for the production of cyclodextrin derivatives.
