Description

Technical Field

[0001] The utility model relates to the technical field of medicine preparation, in particular to a particulate mixing device. Background Art

[0002] In the pharmaceutical process, many particulate raw materials are often used for processing and production. It is necessary to mix and stir various particulate raw materials in a certain proportion. The existing particulate mixing device has the problem of single movement direction of the materials when mixing the particulate raw materials. To improve the mixing effect, the Chinese patent document with the patent application number "CN202220001184.3" provides a mixing and proportioning device for processing bifenthrin granules. It drives the material-changing cylinder to rotate through an electric turntable, increasing the movement amplitude of the materials in the mixing box. During the reciprocating shaking of the mixing box, two telescopic rods expand and contract, and at the same time, two rotating seats rotate on the movable ends of the slide rails, and the movable ends of the two slide rails move on the two slide rails, playing a role in stably supporting the mixing box. However, in actual use, the reciprocating shaking of the mixing box is controlled by the electric turntable, which requires the electric turntable to start and stop frequently, and rotate forward and backward to drive the mixing box to reciprocate and shake, with high performance requirements for the electric turntable, greatly increasing the production equipment cost of the enterprise. Moreover, at this time, both telescopic rods are slidably matched with the mixing box. In fact, the mixing box is still supported by the electric turntable, causing great loss to the electric turntable and being not conducive to long-term use. Content of the Utility Model

[0003] To solve the above technical problems, the utility model provides a particulate mixing device, enabling the materials to be fully mixed while reducing the performance requirements for the rotating structure and reducing the production cost of the enterprise.

[0004] The utility model provides a particulate mixing device to solve the above technical problems. The device includes a base, on which a first support and a second support are provided. A toothed disc and an incomplete driving gear are rotatably provided on the first support. The teeth of the incomplete driving gear mesh with the toothed disc. The incomplete driving gear is fixed to the output end of a rotating motor. A central shaft is fixed to the toothed disc. The other end of the central shaft is connected to the second support through a bearing. A clockwork spring is sleeved on the central shaft. The two ends of the clockwork spring are respectively fixed to the toothed disc and the second support. A horizontal eccentric column is also fixed to the toothed disc. An arc-shaped swing hole is provided on the second support. The horizontal eccentric column is slidably matched with the arc-shaped swing hole and a first mounting ring is fixed to its free end. A horizontal support rod is rotatably provided on the second support. A second mounting ring is fixed to the free end of the horizontal support rod. The first mounting ring and the second mounting ring jointly support a mixing main body, and a stirring mechanism is arranged inside the mixing main body.

[0005] Further, damping structures are provided at both ends of the arc-shaped swinging hole. The damping structures include damping blocks and damping springs. One end of each damping spring is fixed to a damping block, and the other end is fixed to the end wall of the arc-shaped swinging hole. A guide post with one end fixed to the end wall of the arc-shaped swinging hole is provided inside each damping spring.

[0006] Further, a rolling ring is sleeved on the horizontal eccentric column, and a plurality of balls that are circumferentially and evenly arranged and are in rolling fit with the side wall of the arc-shaped swinging hole are provided on the rolling ring.

[0007] Further, the mixing main body includes a housing with a discharge port at the bottom and a cover with a feed port. The stirring mechanism includes a stirring motor provided on the cover, and the output end of the stirring motor extends into the housing and is fixed to a stirrer.

[0008] Further, the mounting ring includes a first arc-shaped clamping arm and a second arc-shaped clamping arm. One end of the first arc-shaped clamping arm is hinged to one end of the second arc-shaped clamping arm, and the other ends are fixed by bolts.

[0009] Further, a mounting ring groove adapted to the mounting ring is provided on the outer wall of the housing.

[0010] Further, valves are provided on both the discharge port and the feed port.

[0011] The beneficial effects of the utility model are as follows: the base is used to support the device, a toothed disc and an incomplete driving gear are rotatably provided on the first support, the gear teeth of the incomplete driving gear mesh with the toothed disc, the incomplete driving gear is fixed to the output end of the rotating motor, and the two ends of the spring are respectively fixed to the toothed disc and the second support. When the rotating motor drives the incomplete gear to rotate, the gear teeth of the incomplete gear mesh with the toothed disc, driving the toothed disc to rotate. When the toothed disc rotates, the spring stores elastic potential energy; when the incomplete gear rotates until the gear teeth are misaligned with the toothed disc, the spring releases elastic potential energy and drives the toothed disc to reverse. Since a horizontal eccentric column is also fixed on the toothed disc, and the horizontal eccentric column cooperates with the arc-shaped swing hole on the second support, when the toothed disc rotates driven by the incomplete gear, the horizontal eccentric column is driven to slide forward in the arc-shaped swing hole, and when the toothed disc drives the toothed disc to reverse under the action of the spring, the horizontal eccentric column is driven to slide reversely in the arc-shaped swing hole. When the mixing body is fixed on the first mounting ring and the second mounting ring, due to the rotation arrangement of the horizontal support rod and the second support, the horizontal eccentric column drives the bottom of the mixing body to swing back and forth around the horizontal support rod as the center when the horizontal eccentric column swings back and forth with the toothed disc. The granular raw materials are further stirred and mixed by the stirring mechanism in the mixing body, thereby further improving the mixing efficiency. That is, the utility model is confident that the rotary motion of the rotating motor is converted into the reciprocating swinging motion of the horizontal eccentric column through the joint action of the incomplete gear, toothed disc and spring spring, so that the mixing body can swing back and forth, strengthen the flow of the raw material particles, improve the mixing effect, and do not need to rely on the forward and reverse rotation of the electric turntable or other rotating motors to achieve reversing, thereby reducing the requirements for the performance of the electric turntable and the rotating motor and the possibility of damage, and the control is simple, which reduces the cost of the production equipment.

DETAILED DESCRIPTION

[0020] With reference to the accompanying drawings, specific embodiments of the present invention will be described in detail.

[0021] Reference Figures 1 to 6 , the utility model provides an embodiment of a particle mixing device.

[0022] A particle mixing device comprises a base 1, wherein a first support 2 and a second support 3 are provided on the base 1, so that a toothed disc 21 and an incomplete driving gear 22 are rotatably provided on the first support 2, the gear teeth of the incomplete driving gear 22 are meshed with the toothed disc 21, the incomplete driving gear 22 is fixed to the output end of a rotating motor 23, a central shaft 24 is fixed to the toothed disc 21, the other end of the central shaft 24 is connected to the second support 3 through a bearing, a spring 25 is sleeved on the central shaft 24, and the two ends of the spring 25 are respectively fixed to the toothed disc 21 and the second support 3. When the rotating motor 23 drives the incomplete gear to rotate, the gear teeth of the incomplete gear mesh with the toothed disc 21, driving the toothed disc 21 to rotate, and the spring 25 stores elastic potential energy when the toothed disc 21 rotates; when the incomplete gear rotates until the gear teeth are staggered with the toothed disc 21, the spring 25 releases the elastic potential energy, driving the toothed disc 21 to reverse.

[0023] A horizontal eccentric post 26 is also fixed on the toothed disc 21. An arc-shaped swing hole 31 is provided on the second support 3. The horizontal eccentric post 26 is slidably engaged with the arc-shaped swing hole 31, and a first mounting ring 27 is fixed at the free end. When the toothed disc 21 rotates driven by the incomplete gear, it drives the horizontal eccentric post 26 to slide forward in the arc-shaped swing hole 31. When the toothed disc 21 drives the toothed disc 21 to reverse under the action of the clockwork spring 25, it drives the horizontal eccentric post 26 to slide backward in the arc-shaped swing hole 31. Further, a rolling ring 261 is sleeved on the horizontal eccentric post 26, and a plurality of balls 262 that are in rolling contact with the side wall of the arc-shaped swing hole 31 are evenly arranged on the circumference of the rolling ring 261. In this way, when the horizontal eccentric post 26 slides in the arc-shaped swing hole 31, the balls 262 are in rolling contact with the inner side wall of the arc-shaped swing hole 31, reducing the friction between the horizontal eccentric post 26 and the arc-shaped swing hole 31 and preventing the horizontal eccentric post 26 from being stuck in the arc-shaped swing hole 31.

[0024] A horizontal support rod 32 coaxial with the central shaft 24 is also rotatably provided on the second support 3. A second mounting ring 33 is fixed at the free end of the horizontal support rod 32. The first mounting ring 27 and the second mounting ring 33 jointly support a mixing main body 4, and a stirring mechanism is provided inside the mixing main body 4. When the mixing main body 4 is supported on the first mounting ring 27 and the second mounting ring 33, the horizontal eccentric post 26 swings back and forth with the toothed disc 21, driving the bottom of the mixing main body 4 to swing back and forth around the horizontal support rod 32 as the center, and further stirring and mixing the granular raw materials through the stirring mechanism inside the mixing main body 4, further improving the mixing efficiency.

[0025] In some embodiments, damping structures are provided at both ends of the arc-shaped swing hole 31. When the horizontal eccentric post 26 swings in the arc-shaped swing hole 31, the damping structures can reduce the collision force between the horizontal eccentric post 26 and the arc-shaped swing hole 31, and absorb it through the damping structures, reducing the risk of fracture of the horizontal eccentric post 26. The damping structures include damping blocks 311 and damping springs 312. One end of the damping spring 312 is fixed to the damping block 311, and the other end is fixed to the end wall of the arc-shaped swing hole 31. A guide post 313 with one end fixed to the end wall of the arc-shaped swing hole 31 is provided inside the damping spring 312. At this time, the damping spring 312 absorbs the impact force of the horizontal eccentric post 26 during swinging, reducing the risk of fracture of the eccentric rod. Preferably, an elastic pad is also provided on the damping block 311 to make it in flexible contact with the damping block 311, further protecting the horizontal eccentric post 26.

[0026] In some embodiments, the mixing main body 4 includes a housing 41 with a discharge port 411 at the bottom and a cover 42 with a feed port 421. The stirring mechanism includes a stirring motor 43 provided on the cover 42, and the output end of the stirring motor 43 extends into the interior of the housing 41 and is fixed to a stirrer 44. The interior of the housing 41 is sealed by the cover 42. During the mixing process, the stirring motor 43 drives the stirrer 44 to rotate, stirring the granular raw materials in the housing 41 to improve the mixing effect. Further, valves are provided on both the discharge port 411 and the feed port 421 to facilitate opening and closing of the discharge port 411 and the feed port 421.

[0027] In some embodiments, the mounting ring includes a first arc-shaped clamping arm 331 and a second arc-shaped clamping arm 332. One end of the first arc-shaped clamping arm 331 is hinged to one end of the second arc-shaped clamping arm 332, and the other ends are fixed by bolts. The upper and lower sides of the mixing main body 4 are clamped and fixed by the first arc-shaped clamping arm 331 and the second arc-shaped clamping arm 332, which is convenient for installation. Further, an installation ring groove 412 adapted to the mounting ring is provided on the outer wall of the housing 41. By inserting the first arc-shaped clamping arm 331 and the second arc-shaped clamping arm 332 into the installation ring groove 412, the position of the arc-shaped clamping arms can be restricted to prevent the mixing main body 4 from slipping off the mounting ring.
