Technical Field

[0001] This utility model belongs to the technical field of pharmaceutical centrifugation equipment, specifically a centrifuge for pharmaceutical production. Background Technology

[0002] Medical centrifuges are an important piece of equipment in medical laboratories, mainly used in medical research, clinical testing, and biopharmaceutical fields. Their basic function is to separate the various components in a mixture according to their density by generating strong centrifugal force through high-speed rotation. There are various types of medical centrifuges, including low-speed centrifuges, high-speed centrifuges, ultracentrifuges, and refrigerated centrifuges, to meet different experimental needs.

[0003] Existing centrifuges only allow for single-size insertion and positioning of test tubes when installing and fixing them. For smaller tubes, the edges cannot be properly engaged, leading to reduced stability during centrifugation. Therefore, the existing centrifuges cannot adapt to different tube diameters, reducing the flexibility of use. Thus, a centrifuge for pharmaceutical production that can clamp and fix tubes of varying diameters is needed. Utility Model Content

A worm gear that meshes with the worm gear is fixedly connected inside the main shaft. An abutment rod for clamping the medicine tube is fixedly connected to the outer wall of the worm gear shaft.

[0007] Furthermore, the clamping mechanism corresponds one-to-one with the positioning hole, the inner diameter of the positioning hole is equal to the inner diameter of the positioning cylinder, the main shaft, worm gear, worm wheel and abutment rod are circumferentially distributed on the outside of the positioning cylinder, and the positioning cylinder is provided with a through groove adapted to the rotation of the abutment rod.

[0008] Furthermore, a sponge pad is fixedly connected to the end of the abutment rod away from the worm gear, and the end of the abutment rod near the worm gear has a U-shaped structure.

[0009] Furthermore, an electric push rod is fixedly connected to the bottom of the positioning cylinder, and a support plate is fixedly connected to the lifting end of the electric push rod. The support plate is slidably connected to the inside of the positioning cylinder.

[0010] Furthermore, the bottom of the main shaft is connected to a transmission mechanism for driving the rotation of the main shaft. The transmission mechanism includes a second motor, the output end of the second motor is fixedly connected to a first gear, the outside of the first gear is meshed with an internal gear ring, the outer wall of the internal gear ring is fixedly connected to an external gear ring, the outside of the external gear ring is meshed with a second gear, and the second gear is fixedly connected to one end of the main shaft.

[0020] The present invention will be further described below with reference to the accompanying drawings.

[0021] like Figures 1 to 5 The centrifuge for pharmaceutical production shown includes a main unit housing 1 and a first motor 2. A cover 11 is hinged to the top of the main unit housing 1, and a ventilation opening is provided at the bottom of the main unit housing 1 to facilitate heat dissipation. A hydraulic rod 12 connects the cover 11 and the main unit housing 1, with both ends of the hydraulic rod 12 hinged for easy opening and closing of the cover 11. The first motor 2 is fixedly connected to the inner wall of the main unit housing 1 and is fixedly connected to the bottom of the main unit housing 1. The output end of the first motor 2 is vertically upward and fixedly connected to a centrifuge disc 21. Positioning holes 22 are evenly distributed around the circumference of the centrifuge disc 21. To clamp the drug tubes, positioning holes 22 are provided inside the centrifuge disc 21. The device includes a clamping mechanism 3, which comprises a positioning cylinder 31 fixedly connected to the bottom of a positioning hole 22. A support base 32 is fixedly connected to the outer wall of the positioning cylinder 31. A main shaft 33 and a worm gear 35 are rotatably connected to the outside of the support base 32. A worm 34 that meshes with the worm gear 35 is fixedly connected to the side wall of the main shaft 33. An abutment rod 36 for clamping the medicine tube is fixedly connected to the outer wall of the shaft of the worm gear 35. Through the cooperation of the clamping mechanism 3 and the transmission mechanism 4, the device can simultaneously adjust the placement point of the medicine tube at each position when clamping and fixing the medicine tube, thereby adapting it to the size of the medicine tube for clamping and fixing, and improving the adaptability of the device.

[0022] To ensure that the abutment rod 36 can rotate and adjust inside the positioning cylinder 31, the opening of the through groove on the outer wall of the positioning cylinder 31 facilitates the angle rotation adjustment of the abutment rod 36. Furthermore, by adjusting the position of the abutment point at the end of the abutment rod 36, its clamping adaptability is improved. The clamping mechanism 3 corresponds one-to-one with the positioning hole 22, and the inner diameter of the positioning hole 22 is equal to the inner diameter of the positioning cylinder 31. The main shaft 33, worm 34, worm wheel 35, and abutment rod 36 are circumferentially distributed on the outside of the positioning cylinder 31, and the positioning cylinder 31 is provided with a through groove to accommodate the rotation of the abutment rod 36.

[0023] In order to provide good cushioning and protection for the drug tube and reduce hard contact with the outer wall of the drug tube, a sponge pad is set to improve the safety of the drug tube. The end of the abutment rod 36 away from the worm gear 35 is wrapped with a sponge pad, and the end of the abutment rod 36 near the worm gear 35 has a U-shaped structure.

[0024] In order to enable the device to adapt to medicine tubes of different lengths, the support plate 38 can be adjusted up and down by activating the electric push rod 37, so that the bottom support height of the medicine tube can be flexibly adjusted, making the device adaptable to support medicine tubes of different lengths. The bottom of the positioning cylinder 31 is fixedly connected to the electric push rod 37, and the lifting end of the electric push rod 37 is fixedly connected to the support plate 38. The support plate 38 is slidably connected inside the positioning cylinder 31.

[0025] To ensure synchronous driving of the clamping mechanisms 3 at all positions, achieving synchronized clamping and fixing of the medicine tubes and reducing the number of clamping and fixing operation steps, a transmission mechanism 4 is provided. This transmission mechanism 4 drives all clamping mechanisms 3 to operate, thereby achieving clamping and loosening of the medicine tubes at external positions, further improving the ease of use of the device. The bottom of the main shaft 33 is connected to the transmission mechanism 4 for driving the rotation of the main shaft 33. The transmission mechanism 4 includes a second motor 41, the output end of which is fixedly connected to a first gear 42. An internal gear ring 43 meshes with the outer side of the first gear 42, and an external gear ring 44 is fixedly connected to the outer wall of the internal gear ring 43. The external gear ring 44 is externally meshed with a second gear 45, and the second gear 45 is fixedly connected to one end of the main shaft 33. The second motor 41 is fixedly connected to the bottom of the positioning cylinder 31 through a support frame. The internal gear ring 43 and the external gear ring 44 are an integral structure, and the internal gear ring 43 and the external gear ring 44 are rotatably connected to the bottom of the positioning cylinder 31 through bearings. The start of the second motor 41 can drive the first gear 42 to rotate. Furthermore, under the meshing of the first gear 42 and the internal gear ring 43, the internal gear ring 43 is rotated, and the external gear ring 44 is rotated at the same time. Furthermore, through the meshing transmission of the second gear 45, the rotation of the second gear 45 can drive the main shaft 33 to rotate.

[0026] The specific working process of this utility model is as follows:

[0027] In use, first connect the first motor 2, the second motor 41, and the electric push rod 37 to an external power source, connect the hydraulic rod 12 to the hydraulic pump, and set corresponding start / stop switches. The operator opens the box cover 11, inserts the medicine tube into the positioning hole 22, and ensures that the bottom of the medicine tube contacts the upper surface of the support plate 38. Then, drive the second motor 41 to rotate the first gear 42, which in turn drives the second gear 42 through the transmission of the internal gear ring 43 and the external gear ring 44. When gear 45 rotates, it drives the main shaft 33 to rotate, which in turn drives the worm wheel 35 to rotate via worm 34. As the worm wheel 35 rotates, the tilt angle of the abutment rod 36 can be adjusted synchronously. Through the adjustment of the abutment rod 36, the abutment end comes into contact with the outer wall of the medicine tube, achieving centering and clamping of the medicine tube. The box cover 11 is then closed. By starting the first motor 2, the centrifuge disc 21 and the clamping mechanism 3 can be driven to rotate rapidly, thereby achieving centrifugal treatment of the medicine inside the medicine tube.
