Description

Technical Field

[0001] This utility model relates to the field of pelleting machines, and more specifically, to a pelleting device for adjusting the size of pellets used in pharmaceutical production. Background Technology

[0002] A pelletizing machine is a device that can press medicines into lines and then process the lines into pill-shaped medicines. Patent publication number CN218961325U discloses a horizontal spherical pelletizing device, including a machine box. A strip-making machine is installed inside the machine box. The discharge end of the strip-making machine is fixedly connected to a first guide plate. A pelletizing device is located directly below the first guide plate. The pelletizing device includes a guide roller, a first motor, a distribution box, a pelletizing roller, and a second motor. One end of the guide roller is fixedly installed on the outer wall of the machine box through a bearing. The output end of the first motor is fixedly connected to one end of the guide roller. The distribution box is fixedly connected below the guide roller. A set of symmetrically arranged pelletizing rollers is located directly below the distribution box. This utility model, by setting a collection device, allows the produced pills to fall onto a first screen. Oversized pills are intercepted on the first screen, while smaller pills fall onto the bottom of the collection box through a second screen, further improving production standards.

[0003] Patent publication number CN212913885U discloses an improved pelleting wheel for a pelleting machine, capable of adjusting the diameter of the pellets. The wheel includes a limiting shaft and a pelleting wheel. A positioning slider is provided on the outer side of the limiting shaft, and a sealing ring is provided on the outer side of the positioning slider. The pelleting wheel is fixed to the outer side of the sealing ring, and a positioning nut is provided on the front side of the pelleting wheel. An adjusting disc is provided on the outer side of the pelleting wheel, and a positioning groove is provided on the front surface of the pelleting wheel. The positioning nut and the sealing gasket cooperate to facilitate the disassembly and replacement of the pelleting wheel, avoiding complex replacement steps that reduce the practicality of the device. The positioning groove and the limiting plate allow for the disassembly of the adjusting disc, preventing inconvenience in size adjustment and ensuring the device's practicality. The anti-stick layer is made of polytetrafluoroethylene (PTFE), which has an extremely low coefficient of friction, preventing the surface of the adjusting disc from becoming sticky with medication during use and making cleaning difficult.

[0004] In existing technologies, pelleting devices mainly rely on the rotation of two pelleting rollers to manufacture pills. The size of the pills also depends on the distance between the two pelleting rollers. However, when the specifications of the pills need to be changed, i.e., when the pills are of different sizes, the pelleting rollers can only be disassembled and reassembled with suitable roller molds. This increases the workload of the workers and also increases the overall limitations of the pelleting device. Therefore, there is a need for a pelleting device that can effectively and quickly adjust the distance between the rollers to meet the needs of various pharmaceutical requirements.

[0031] Example 1:

[0032] Please see Figure 1-5 A pellet-making device for adjusting the size of pills used in pharmaceutical production includes a pellet-making machine body 1. A mounting box 2 is fixedly installed on the side of the pellet-making machine body 1. A pellet-making roller 3 is rotatably installed on the outside of the front of the mounting box 2. A motor 4 is fixedly installed inside the mounting box 2. A double-threaded screw 5 is fixedly sleeved on the output shaft of the motor 4. A transmission frame 6 is threaded on the surface of the double-threaded screw 5. A mounting frame 7 is provided on the side of the transmission frame 6. A second motor 302 is fixedly installed inside the mounting frame 7. A support bearing 301 is rotatably installed on the output shaft of the second motor 302.

[0033] It should be noted that the pelletizing machine body 1 in this utility model belongs to existing mature technology, including its internal process of forming the raw materials into a thread, and then transporting the thread through the pelletizing roller 3 to form a spherical shape. Therefore, this application will not elaborate on this aspect.

[0034] The surface of the mounting box 2 is provided with a sliding groove for the support bearing 301 to slide left and right. The output shaft of the motor 302 is fixedly connected to the pelletizing roller 3. There are two transmission frames 6 and two mounting frames 7. One mounting frame 7 is fixedly connected to the transmission frame 6, and a vibration component 8 is fixedly connected to the side of the other mounting frame 7. A fixing rod 601 is fixedly installed on the surface of the transmission frame 6, which is movably connected to the mounting frame 7. A fixing frame 602 is fixedly installed at the top of the fixing rod 601. A convex ring is integrally formed at the end of the double-threaded screw 5. The convex ring is rotatably installed inside the mounting box 2. The interior of the mounting box 2 is provided with a rotating groove that matches the convex ring.

[0035] Specifically, the support bearing 301 enables the motor 302 to provide support inside the mounting box 2 when driving the pelletizing roller 3 for position adjustment. The sliding groove limits the movement of both the support bearing 301 and the pelletizing roller 3 as a whole, ensuring normal adjustment of the spacing between the pelletizing rollers 3. The double-grooved screw 5, in conjunction with the convex ring and the rotating groove, provides rotational limit support for the double-grooved screw 5, preventing excessive weight on its surface from causing deformation and affecting transmission.

[0036] The vibration assembly 8 includes a motor 801, the output shaft of which is fixedly sleeved with a disc 802. A fixing rod is fixedly installed at one end of the bottom surface of the disc 802. A connecting plate 803 is rotatably installed on the surface of the fixing rod. A connecting frame 804 is rotatably installed at one end of the connecting plate 803. A transmission plate 805 is fixedly installed on one side of the connecting frame 804. There are two transmission plates 805. The two transmission plates 805 are fixedly connected to the same synchronization plate 806 on opposite sides. A guide rod 807 and a spring 808 are fixedly connected to the inner side of the transmission plate 805 respectively. One end of the guide rod 807 is fixedly connected to the side of the mounting frame 7. The guide rod 807 is movably sleeved inside the transmission frame 6. The other end of the spring 808 is fixedly connected to the side of the transmission frame 6. The motor 801 is fixedly installed inside the fixing frame 602. The synchronization plate 806 has an arc-shaped structure.

[0037] Specifically, the connecting plate 803 is rotated at both ends so that the connecting frame 804 can drive the transmission plate 805 to reciprocate linearly with the rotation of the disc 802. This linear motion is limited by the guide rod 807 sleeved inside the transmission frame 6, thereby ensuring the overall reciprocating vibration of the shot-making roller 3. Then, the mutual structure of the synchronous plate 806 can effectively adapt to the arc structure on the side of the double-grooved screw 5 to prevent collisions during vibration. The spring 808 is used to provide a certain speed reduction effect during back-and-forth vibration, preventing the workpiece from being damaged due to excessive speed changes, and extending the service life of the device.

[0038] The working principle of this utility model is as follows: The drive mounting frame 7 drives the pelletizing roller 3 to rotate. When the two pelletizing rollers 3 rotate, the motor 801 is started to drive the disc 802 to rotate, so that the connecting plate 803, together with the connecting frame 804, drives the transmission plate 805 to reciprocate linearly. This causes the pelletizing roller 3 at the corresponding position to vibrate through the mounting frame 7, thereby realizing the pellet rolling operation. When the diameter of the pellet needs to be changed, the drive motor 4 drives the double-grooved screw 5 to rotate, and then, together with the transmission frame 6, drives the two mounting frames 7 to move in opposite directions or towards each other, so that the distance between the pelletizing rollers 3 increases or decreases until the distance between them is suitable for the diameter of the pellet. Then, the rotation of the output shaft of the motor 4 is stopped. Finally, the mounting frame 7 and the vibration component 8 are started as usual, one pelletizing roller 3 rotates, and the other rotates and vibrates to realize pellet rolling.

[0039] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
