Description

Technical Field

[0001] The utility model relates to the technical field of adding devices, in particular to a uniform adding device for a large-particle-size cross-linked polyvinylpyrrolidone forming agent. Background Art

[0002] Cross-linked polyvinylpyrrolidone is a pharmaceutical excipient, which is a water-insoluble synthetic cross-linked vinylpyrrolidone homopolymer. Cross-linked polyvinylpyrrolidone is prepared by using sodium hydroxide solution as an initiator and adding vinylpyrrolidone through a cross-linking polymerization reaction. Phase change occurs during the cross-linking polymerization reaction. During the reaction, an adding device is required to quantitatively and evenly add large-particle cross-linked polyvinylpyrrolidone forming agent.

[0003] The patent with application number 202321415704.6 discloses an automatic powder additive adding device, which relates to the technical field of automatic powder additive adding shaking device. The automatic powder additive adding device comprises a box body, the bottom of which is fixedly connected to a supporting leg, a material port is provided on the left side of the box body, a discharge port is provided at the bottom of the box body, and a shaking device is provided on the top of the box body. The shaking device comprises a hollow column, the top of which is fixedly connected to a disc, the bottom of the hollow column passes through and is fixedly connected to the top of the box body, the top of the disc is fixedly connected to a limiting block, and the turntable and the disc surface are both provided with groove one and groove two.

[0004] The above technical solution utilizes the rotation of the turntable to connect groove one and groove two and then add the molding agent. However, since large particles of molding agent are prone to clogging in the grooves, and groove one and groove two cannot quantitatively control the added molding agent, the uniform quantitative addition effect is poor. Utility Model Content

[0005] The purpose of the utility model is to provide a device for uniformly adding a large-particle cross-linked polyvinylpyrrolidone molding agent in view of the deficiencies in the prior art, which realizes the function of avoiding blockage of quantitative transportation through a vibration motor structure in conjunction with a detachable and fixed quantitative tube structure, and solves the problem of poor uniform quantitative addition effect of the molding agent.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a device for uniformly adding a large-particle cross-linked polyvinylpyrrolidone forming agent, comprising an adding device main body and a storage cylinder and a discharging cylinder installed at both ends of the adding device main body, the storage cylinder and the discharging cylinder are symmetrically fixed with mounting rings at the ends close to each other, and the storage cylinder and the discharging cylinder are installed with rotating plates at the ends away from each other, the two rotating plates are provided with staggered discharging holes, and a rotating shaft is fixed between the two rotating plates, and a quantitative tube is detachably fixed between the two mounting rings on the same side.

[0007] Preferably, a vibration motor is fixedly mounted on the side wall of the adding device body, and rubber rings are fixedly sleeved on the outer walls of the storage cylinder and the discharge cylinder.

[0008] Furthermore, mounting plates are fixed to the inner walls of the storage cylinder and the discharging cylinder, and motors are fixed to the side walls of the mounting plates.

[0009] Furthermore, both ends of the rotating shaft are rotatably inserted into the mounting plate through bearings, and the shaft of the motor is fixedly connected to the rotating shaft.

[0010] Furthermore, sealing gaskets are embedded and fixed at both ends of the quantitative tube, and the sealing gaskets are tightly connected to the mounting ring.

[0011] Furthermore, anti-slip portions are fixed on both sides of the outer wall of the quantitative tube, and threaded sleeves are slidably sleeved on both ends of the quantitative tube.

[0012] Furthermore, the inner wall of the threaded sleeve abuts against the anti-slip portion, and the threaded sleeve is threadedly sleeved on the mounting ring.

[0013] The beneficial effects of the utility model are:

[0014] (1) The utility model provides a storage cylinder and a discharge cylinder at both ends of the adding device body, and rotating plates are installed in the storage cylinder and the discharge cylinder. The large-particle-size cross-linked polyvinylpyrrolidone molding agent is embedded in the storage cylinder. The driving motor drives the two rotating plates to rotate through the rotating shaft, and during the rotation, the top rotating plate grid fixes the discharge hole corresponding to the mounting ring, and the large-particle-size cross-linked polyvinylpyrrolidone molding agent falls into the quantitative cylinder along the discharge hole and the mounting ring. At the same time, the vibration motor is started synchronously to avoid the blockage of large particles during the conveying process. After the quantitative cylinder is fully conveyed, the driving motor rotates again to connect the bottom of the quantitative cylinder with the discharge hole. At the same time, the top of the quantitative cylinder is sealed with the rotating plate, so that the large-particle-size cross-linked polyvinylpyrrolidone molding agent in the quantitative cylinder falls from the discharge cylinder, which is convenient for quantitative and uniform conveying of the large-particle-size cross-linked polyvinylpyrrolidone molding agent, thereby improving the conveying effect of the large-particle-size cross-linked polyvinylpyrrolidone molding agent.

[0015] (2) The utility model has anti-slip parts fixedly sleeved on both ends of the metering cylinder, and a threaded sleeve is provided on the metering cylinder. After the threaded sleeve is threadedly sleeved on the mounting ring, the metering cylinder is kept fixed. After the threaded sleeve is unscrewed, it is convenient to replace metering cylinders of different sizes. It is suitable for the transportation of different quantitative large-particle-size cross-linked polyvinylpyrrolidone molding agents.

[0016] In summary, the utility model has the advantages of good quantitative and uniform conveying effect and is suitable for conveying cross-linked polyvinylpyrrolidone forming agents with different quantitative and large particle sizes. BRIEF DESCRIPTION OF THE DRAWINGS
