Description

Technical Field

[0001] This application relates to the field of vibrator technology, and in particular to a vibrator suitable for the pharmaceutical industry. Background Technology

[0002] A pneumatic vibrator is a device that uses compressed air as its power source, primarily used in industries such as pharmaceuticals. In pharmaceutical production, pneumatic vibrators effectively solve material blockage problems, ensuring smooth production processes. They can also be used for screening and conveying pharmaceutical raw materials. For example, in the extraction of medicinal plants, pneumatic vibrators can be used to screen pharmaceutical raw materials, improving extraction efficiency and purity.

[0003] The pneumatic vibrator utilizes high-pressure gas discharged from an air compressor, which is introduced into the product's air inlet through an air pipe. When the gas pushes the piston upward, the gas in the upper chamber of the piston is compressed and discharged through the exhaust port. When the piston reaches its upper limit, the gas flow direction is automatically switched through the slot and air passage, allowing gas to enter the upper chamber of the piston. The high-pressure gas pushes the piston downward to the lower limit, ending the first cycle and starting the second cycle. This continuous reciprocating cycle causes the vibrator to produce translational and oscillating motions, thereby generating vibrational force.

[0004] However, in order to achieve a complete fit with the inner wall of the pneumatic vibrator, the piston requires high machining precision. Furthermore, due to the extremely small gap between the piston and the inner wall of the pneumatic vibrator, the piston is also relatively inconvenient to assemble. Therefore, this application proposes a vibrator suitable for the pharmaceutical industry. Utility Model Content

[0005] To address the aforementioned problems, this application provides a vibrator suitable for the pharmaceutical industry.

[0006] This application provides a vibrator suitable for the pharmaceutical industry, which adopts the following technical solution:

[0007] A vibrator suitable for the pharmaceutical industry includes: a base, a protective outer shell mounted on one side of the base, a cylinder sleeve mounted inside the protective outer shell, and a sliding core slidably disposed inside the cylinder sleeve. An air inlet / outlet distributor is fixedly provided between the protective outer shell and one end of the cylinder sleeve. A left-side cavity is formed in the gap between the air inlet / outlet distributor, the cylinder sleeve, and the sliding core, and a right-side cavity is formed in the gap between the base, the cylinder sleeve, and the sliding core.

[0008] The slide core is provided with a first air passage groove and a first internal air channel for discharging gas from the inlet / outlet air distributor into the right cavity. The slide core is also provided with a second air passage groove and a second internal air channel for discharging gas into the left cavity when the air pressure in the right cavity increases and the slide core moves to the left. A first spring is provided on one side of the inlet / outlet air distributor for pushing the slide core into the right cavity.

[0009] By adopting the above technical solution, by changing the air path in the vibrator, the sliding core can be driven to move back and forth in the cylinder sleeve to generate vibration. During the back and forth movement, the sliding core does not need to be completely in contact with the inner wall of the cylinder sleeve. It is only necessary to ensure the full runout of the outer circle and the dimensional tolerance. This makes it easier to control the accuracy of the sliding core and facilitates assembly.

[0010] Preferably, the threaded hole at the edge of the base is provided with a plurality of threaded protective sleeves, and the end of the air inlet / outlet distributor opposite to the cylinder liner is fixedly provided with an air nozzle connector, and a muffler is provided between the air nozzle connector and the air inlet / outlet distributor.

[0011] By adopting the above technical solution, the threaded protective sleeve can effectively protect the internal threads of the base and prevent them from being damaged. The base can be installed in the required area by using the bolt connection threaded hole.

[0012] Preferably, a support cylinder is fixedly provided inside the air nozzle connector, and an air intake hose is inserted into the gap between the air nozzle connector and the support cylinder. Several rubber retaining rings are fixedly provided on the outer wall of the air intake hose, and the several rubber retaining rings are engaged in several slots opened in the air nozzle connector.

[0013] By adopting the above technical solution, the air intake hose and the air nozzle connector can be initially connected by inserting the air intake hose into the gap between the air nozzle connector and the support cylinder. The air intake hose and the air nozzle connector can be further connected and fixed by inserting the rubber retainer into the corresponding slot.

[0014] Preferably, the top and bottom of the support cylinder are respectively provided with two sets of inclined rotating plates. One side of the top of the rotating plate is fixed with a pressure rod for squeezing and fixing the air inlet hose by the compressed gas after the vibrator is vented. The top and bottom of the support cylinder are provided with through holes for the pressure rod to pass through. The top of the two sets of rotating plates are respectively fixed with two sets of second springs. The ends of the two sets of second springs opposite to the rotating plates are respectively fixed to the top and bottom of the inner side of the support cylinder.

[0015] By adopting the above technical solution, the compressed gas inside the air inlet hose can push the rotating plate to rotate, and the pressure rod can be used to firmly press the air inlet hose into the air nozzle connector for further fixation, so that the air inlet hose is not easy to fall off and leak air when the vibrator vibrates.

[0016] In summary, this application includes at least one of the following beneficial technical effects:

[0017] 1. By changing the air path inside the vibrator, the sliding core can be driven to move back and forth inside the cylinder sleeve to generate vibration. During the reciprocating motion, the sliding core does not need to be completely in contact with the inner wall of the cylinder sleeve. It is only necessary to ensure the full runout of the outer circle and the dimensional tolerance. The requirement for high-precision dimensions is simple, which makes it easier to control the accuracy of the sliding core, facilitates assembly, and makes it easy to process on high-precision processing equipment such as grinding machines, saving processing costs and improving processing efficiency.

[0018] 2. By inserting the air inlet hose into the gap between the air nozzle connector and the support cylinder, the air inlet hose and the air nozzle connector can be initially connected. By using rubber retaining rings to snap into the corresponding slots, the air inlet hose and the air nozzle connector can be further connected and fixed. After the air is introduced into the air inlet hose, the internal compressed gas pushes the rotating plate to rotate, and the pressure rod uses a pressure rod to firmly press the air inlet hose into the air nozzle connector for further fixation. This makes it less likely for the air inlet hose to fall off and leak air when the vibrator vibrates, thus improving the practicality of the vibrator. Attached Figure Description

Detailed Implementation

[0024] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0025] This application discloses a vibrator suitable for the pharmaceutical industry.

[0026] A vibrator suitable for the pharmaceutical industry, as described above. Figure 1-2 It includes: a base 1, a protective outer shell 3, a cylinder sleeve 9, and a sliding core 4. Several threaded protective sleeves 2 are provided in the threaded holes opened at the edge of the base 1. The threaded protective sleeves 2 can effectively protect the internal threads of the base 1 and prevent them from being damaged. The base 1 can be installed in the required area by using bolts to connect the threaded holes.

[0027] Reference Figure 1-2 The outer protective sleeve 3 is installed on one side of the base 1, the cylinder sleeve 9 is installed inside the outer protective sleeve 3, and the sliding core 4 is slidably disposed inside the cylinder sleeve 9. The outer protective sleeve 3 can protect the internal components of the vibrator from the outside of the vibrator, and the cylinder sleeve 9 can support and limit the sliding core 4. The sliding core 4 can be made of wear-resistant material with the same diameter as the inner diameter of the cylinder sleeve 9.

[0028] Reference Figure 1-2 An inlet / outlet air distributor 8 is fixedly provided between the outer protective sleeve 3 and one end of the cylinder liner 9. The gap between the inlet / outlet air distributor 8, the cylinder liner 9 and the sliding core 4 forms a left cavity 91, and the gap between the base 1, the cylinder liner 9 and the sliding core 4 forms a right cavity 92. The base 1 and the inlet / outlet air distributor 8 can seal both ends of the cylinder liner 9 and form a left cavity 91 and a right cavity 92 at both ends. The inlet / outlet air distributor 8 can distribute the incoming compressed gas.

[0029] Reference Figure 1 The inlet and outlet air distributor 8 is fixedly provided with an air nozzle connector 7 at one end away from the cylinder liner 9. A silencer 6 is provided between the air nozzle connector 7 and the inlet and outlet air distributor 8. Compressed gas will enter the inlet and outlet air distributor 8 through the air nozzle connector 7. The silencer 6 can reduce the noise when the vibrator is intake.

[0030] Reference Figure 1-2 The sliding core 4 has a first air passage 41 for discharging gas from the inlet / outlet air distributor 8 into the right cavity 92 and a first internal air passage 43. The sliding core 4 also has a second air passage 42 and a second internal air passage 44 for discharging gas into the left cavity 91 when the air pressure in the right cavity 92 increases and the sliding core 4 moves to the left. A first spring 5 is provided on one side of the inlet / outlet air distributor 8 for pushing the sliding core 4 into the right cavity 92. The first air passage 41 and the second air passage 42 are both located on the outer wall of the sliding core 4, while the first internal air passage 43 and the second internal air passage 44 are located at both ends of the sliding core 4. The first spring 5 is fixedly connected between the inlet / outlet air distributor 8 and the sliding core 4.

[0031] Compressed gas enters the air passage of the sliding core 4 sequentially from the air nozzle connector 7 and the inlet / outlet air distributor 8 in the direction of the arrow. At this time, the compressed gas will enter the internal air passage 43 of the first sliding core through the first air passage groove 41. The compressed gas in the internal air passage 43 of the first sliding core will enter the right side cavity 92, causing the air pressure in the right side cavity 92 to increase instantaneously, thereby causing the sliding core 4 to move rapidly to the left.

[0032] During the movement of the sliding core 4, the second air passage groove 42 and the air outlet of the inlet and outlet air distributor 8 are connected. At this time, the gas will instantly enter the left cavity 91 along the second air passage groove 42 and the internal air passage 44 of the second sliding core, causing the air pressure in the left cavity 91 to increase instantaneously. This causes the sliding core 4 to move quickly to the right. During the movement of the sliding core 4 to the right, when the first air passage groove 41 and the air outlet of the inlet and outlet air distributor 8 are connected, the gas will instantly enter the right cavity 92. The air pressure in the right cavity 92 increases, and it begins to move back and forth, thereby generating vibration. This vibrator is suitable for the medical industry. In the pharmaceutical production process, vibration can effectively solve the problem of material blockage and ensure the smooth progress of the production process. Both the left cavity 91 and the right cavity 92 are equipped with exhaust holes for exhaust. The diameter of the exhaust holes is small. The amount of compressed gas entering the left cavity 91 and the right cavity 92 is greater than the amount discharged through the exhaust holes. This ensures normal exhaust and also causes the air pressure in the left cavity 91 and the right cavity 92 to increase instantaneously, thus ensuring the movement of the sliding core 4.

[0033] Reference Figure 1 , Figure 3 and Figure 4 A support cylinder 71 is fixedly installed inside the air nozzle connector 7. An air intake hose 72 is inserted into the gap between the air nozzle connector 7 and the support cylinder 71. The gap between the air nozzle connector 7 and the support cylinder 71 forms an annular groove. By inserting one end of the air intake hose 72 into the groove, one end of the air intake hose 72 can be supported and limited.

[0034] Reference Figure 1 and Figure 3 The outer wall of the air intake hose 72 is fixed with several rubber retaining rings 73. The rubber retaining rings 73 are engaged in several slots opened in the air nozzle connector 7. By engaging the rubber retaining rings 73 into the corresponding slots, the air intake hose 72 and the air nozzle connector 7 can be further connected and fixed.

[0035] Reference Figure 1 , Figure 3 and Figure 4The support cylinder 71 has two sets of inclined rotating plates 74 at its top and bottom. A pressure rod 75 is fixed on one side of the top of the rotating plate 74 for squeezing and fixing the air intake hose 72 by the compressed gas after the vibrator is ventilated. The support cylinder 71 has through holes at its top and bottom for the pressure rod 75 to pass through. Two sets of second springs 76 are fixed on the top of the two sets of rotating plates 74 respectively. The ends of the two sets of second springs 76 opposite to the rotating plates 74 are fixed on the top and bottom of the inner side of the support cylinder 71 respectively. The through holes of the support cylinder 71 can provide space for the pressure rod 75 to move after the rotating plates 74 rotate. The second springs 76 can provide elastic support for the rotating plates 74. The air intake hose 72 is connected to the external air compressor.

[0036] After air is introduced through the intake hose 72, the compressed gas inside pushes the rotating plate 74, causing it to rotate to one side. After the rotating plate 74 rotates, the pressure rod 75 can firmly hold the intake hose 72 against the air nozzle connector 7 for further fixation, making it less likely for the intake hose 72 to fall off and leak air when the vibrator vibrates.

[0037] The implementation principle of a vibrator applicable to the pharmaceutical industry according to an embodiment of this application is as follows:

[0038] When in use, the staff can install the base 1 in the required area, and then insert one end of the air intake hose 72 into the gap between the air nozzle connector 7 and the support cylinder 71. When inserted, the rubber retainer 73 on the outer wall of the air intake hose 72 will be inserted into the corresponding slot to connect and fix the air intake hose 72 and the air nozzle connector 7.

[0039] Next, air is introduced through the air intake hose 72. When air is introduced, the compressed gas will push the rotating plate 74, causing the rotating plate 74 to rotate to one side. After the rotating plate 74 rotates, the pressure rod 75 can be used to firmly press the air intake hose 72 into the air nozzle connector 7 for further fixation, so that the air intake hose 72 is not easy to fall off and leak air when the vibrator vibrates.

[0040] At the same time, compressed gas will enter the air passage of the sliding core 4 sequentially from the air nozzle connector 7 and the air inlet / outlet distributor 8 in the direction of the arrow. At this time, the compressed gas will enter the air passage 43 inside the first sliding core through the first air passage groove 41. The compressed gas in the air passage 43 inside the first sliding core will enter the right side cavity 92, causing the air pressure in the right side cavity 92 to increase instantly, thereby causing the sliding core 4 to move quickly to the left.

[0041] During the movement of the sliding core 4, the second air passage groove 42 and the air outlet of the inlet and outlet air distributor 8 are connected. At this time, the gas will instantly enter the left cavity 91 along the second air passage groove 42 and the internal air passage 44 of the second sliding core, causing the air pressure in the left cavity 91 to increase instantly, thereby causing the sliding core 4 to move quickly to the right. During the movement of the sliding core 4 to the right, when the first air passage groove 41 and the air outlet of the inlet and outlet air distributor 8 are connected, the gas will instantly enter the right cavity 92, and the air pressure in the right cavity 92 will increase, starting the reciprocating motion, thereby generating vibration. During the reciprocating motion, the sliding core 4 does not need to be completely in contact with the inner wall of the cylinder sleeve 9. It only needs to ensure the full runout of the outer circle and the dimensional tolerance. The requirement for high-precision dimensions is simple, which makes it easier to control the accuracy of the sliding core 4 and makes it easier to process on high-precision processing equipment such as grinding machines, saving processing costs and improving processing efficiency.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
