Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical powder production, and in particular to a sealing structure for a dispensing machine. Background Technology

[0002] In the field of pharmaceutical powder production and packaging, filling machines play a crucial role. Components such as the stirring shaft and impeller within the hopper are indispensable for ensuring material uniformity. However, during actual operation, dust generation has consistently hampered the efficient and stable operation of the filling machine and the assurance of product quality.

[0003] Traditional dispensing machines simply install dustproof sealing rings at the junction of the hopper and the mixing shaft. However, the sealing effect is insufficient to meet production requirements. When the mixing shaft rotates continuously, the sealing rings cannot fit tightly against the shaft, allowing a large amount of dust to easily penetrate the sealing rings and enter the bearing area. This dust intrusion not only accelerates bearing wear, causing frequent malfunctions, increasing maintenance frequency and costs, and reducing production efficiency, but can also lead to equipment downtime due to bearing damage, affecting the continuity of the entire production line.

[0004] Secondly, dust tends to accumulate at the junction of the sealing ring and the stirring shaft. Because the structure of this area is not conducive to dust discharge, the accumulated dust gradually builds up, providing a breeding ground for bacteria. Once bacteria grow, they will contaminate the powder products that come into contact with them, seriously affecting the quality and safety of the products.

[0005] Furthermore, traditional dustproof seals have poor wear resistance. During high-speed rotation, the agitator shaft rubs against the seals continuously, causing them to wear out quickly. This leads to a rapid decline in their sealing performance, creating a vicious cycle that further exacerbates the problem of dust entering the bearings, shortens the lifespan of the seals, and significantly reduces the equipment maintenance cycle.

[0006] Therefore, it is necessary to provide a new sealing structure for the dispensing machine to solve the above-mentioned technical problems. Utility Model Content

[0007] To solve the above-mentioned technical problems, this utility model provides a sealing structure for a dispensing machine.

[0008] The present invention provides a sealing structure for a dispensing machine, comprising: a bin, a bearing seat at the upper end of the bin, a motor gearbox above the bearing seat, the motor gearbox being fixedly installed on the upper wall of the bin, and a bearing component being installed and connected in the bearing seat; and a high-efficiency sealing mechanism, comprising a dustproof sealing ring, a sealing lip at both ends of the dustproof sealing ring, and two symmetrically aligned side strips on the outer side wall of the dustproof sealing ring.

[0009] Preferably, the inner ring wall of the bearing component is symmetrically provided with two limiting slots, and the two alignment side strips are slidably connected to the two limiting slots respectively.

[0010] Preferably, the bearing component has a top limiting ring at its top end and a bottom limiting ring at its bottom end. The top limiting ring has a main limiting ring opening, and the bottom limiting ring has a secondary limiting ring opening.

[0011] Preferably, the main limiting ring and the secondary limiting ring have the same specifications.

[0012] Preferably, two inner insert rods are symmetrically provided on the wall of the bottom limiting ring, and two insertion ports are symmetrically provided on the bearing component, with the two inner insert rods slidably connected to the two insertion ports respectively.

[0013] Preferably, one end of each of the two inner insert rods is provided with a screw head, and two mating interfaces are symmetrically provided on the top limiting ring. The two screw heads are slidably connected to the two mating interfaces respectively, and a nut is provided at each of the two mating interfaces. The two nuts are threadedly connected to the two screw heads respectively.

[0014] Preferably, both inner insert rods are provided with embedded annular grooves, and each of the two embedded annular grooves is equipped with a mating magnetic ring. Both inserts are provided with concave annular grooves, and each of the two concave annular grooves is equipped with a mating magnetic ring.

[0015] Compared with related technologies, the sealing structure for a dispensing machine provided by this utility model has the following beneficial effects:

[0016] 1. This utility model provides a special structure for the dustproof sealing ring and its sealing lip, which allows the sealing lip to fit tightly against the stirring shaft during the rotation of the stirring shaft, effectively blocking the spread of dust and preventing it from entering the critical parts inside the equipment. This greatly reduces the risk of equipment damage caused by dust pollution, extends the service life of the equipment, reduces equipment maintenance costs and downtime, and ensures the stable and efficient operation of the dispensing machine.

[0017] 2. This utility model provides a reliable limiting effect for the dustproof sealing ring by inserting and combining the bottom limiting ring and the top limiting ring, and using magnetic force to attract the inner insert rod and the nut and screw head for fastening. Even under conditions such as vibration caused by long-term operation of the equipment, it can ensure that the dustproof sealing ring and the sealing lip do not undergo slight displacement, and always maintain a good sealing state, further improving the reliability and stability of the seal, and providing a solid sealing foundation for the precise dispensing operation of the dispensing machine.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please refer to the following: Figures 1 to 3 A sealing structure for a dispensing machine includes: a bin 1, a bearing seat 2 at the upper end of the bin 1, a motor gearbox 3 above the bearing seat 2, the motor gearbox 3 being fixedly installed on the upper end wall of the bin 1, and a bearing component 4 being installed and connected in the bearing seat 2; and a high-efficiency sealing mechanism, including a dustproof sealing ring 41, with sealing lips 411 at both ends of the dustproof sealing ring 41, and two symmetrically aligned side strips 42 on the outer side wall of the dustproof sealing ring 41.

[0024] In the specific implementation process, such as Figure 1 and Figure 2 As shown, two limiting slots are symmetrically provided on the inner ring wall of the bearing component 4, and the two aligning side strips 42 are slidably connected to the two limiting slots respectively.

[0025] It should be noted that: the two aligning side strips 42 on the side wall of the dustproof sealing ring 41 are slid into the two limiting slots in the bearing component 4 to complete the installation of the dustproof sealing ring 41. The two sealing lips 411 on both sides of the dustproof sealing ring 41 can fit tightly against the stirring shaft. The sealing lips 411 are thin and elastic, and their inner diameter is smaller than that of the dustproof sealing ring 41, so they can fit tightly against the stirring shaft to prevent dust from spreading to other places and to prevent bacteria from being generated by dust accumulation.

[0026] refer to Figure 1 and Figure 2 As shown, a top limiting ring 5 is provided at the top of the bearing component 4, and a bottom limiting ring 51 is provided at the bottom of the bearing component 4. The top limiting ring 5 is provided with a main limiting ring opening, and the bottom limiting ring 51 is provided with a secondary limiting ring opening.

[0027] refer to Figure 2As shown, the main limit ring and the secondary limit ring have the same specifications.

[0028] It should be noted that the specifications of the main limit ring and the secondary limit ring are the same as the specifications of the dustproof sealing ring 41, so that the dustproof sealing ring 41 can be limited without affecting the installation with the stirring shaft.

[0029] refer to Figure 2 and Figure 3 As shown, two inner rods 6 are symmetrically arranged on the wall of the bottom limiting ring 51, and two sockets are symmetrically arranged on the bearing component 4. The two inner rods 6 are slidably connected to the two sockets respectively.

[0030] It should be noted that the two inner rods 6 on the bottom limiting ring 51 are slidably inserted into the two sockets in the bearing component 4, and cooperate with the top limiting ring 5 so that it can be combined with the bearing component 4.

[0031] refer to Figure 2 and Figure 3 As shown, each of the two inner insert rods 6 has a screw head 7 at one end, and two matching interfaces are symmetrically provided on the top limiting ring 5. The two screw heads 7 are slidably connected to the two matching interfaces respectively, and each of the two matching interfaces has a nut 71, which is threadedly connected to the two screw heads 7 respectively.

[0032] It should be noted that: the two nuts 71 are rotated and installed in sequence to tighten them with the two screw heads 7, so as to effectively limit the dustproof sealing ring 41 by using the top limiting ring 5 and the bottom limiting ring 51.

[0033] refer to Figure 3 As shown, both inner insert rods 6 are provided with embedded annular grooves, and each embedded annular groove is equipped with a mating magnetic ring 8. Both inserts are provided with concave annular grooves, and each concave annular groove is equipped with a mating magnetic ring 81. The mating magnetic ring 81 and the mating magnetic ring 81 have opposite magnetic poles.

[0034] It should be noted that: by sliding the two inner rods 6 on the bottom limiting ring 51 into the two sockets in the bearing component 4, the mating magnetic rings 81 in the two sockets will attract the mating magnetic rings 8 on the two inner rods 6 by magnetic force, thus achieving automatic combination and positioning.

[0035] The working principle of the sealing structure of the dispensing machine provided by this utility model is as follows: The two aligning side strips 42 on the side wall of the dustproof sealing ring 41 are slidably inserted into the two limiting slots in the bearing component 4 to complete the installation of the dustproof sealing ring 41. Then, the two inner insert rods 6 on the bottom limiting ring 51 are slidably inserted into the two inserts in the bearing component 4. The mating magnetic rings 81 in the two inserts use magnetic force to attract the fitting magnetic rings 8 on the two inner insert rods 6 to complete the automatic combination and positioning. Then, the top limiting ring 5 is installed on the two screw heads 7, and then the two nuts 71 are rotated and installed in sequence to tighten them with the two screw heads 7. This achieves effective limiting of the dustproof sealing ring 41 by the top limiting ring 5 and the bottom limiting ring 51, preventing slight displacement of the dustproof sealing ring 41 and the two sealing lips 411 during operation, and further preventing dust from entering.

[0036] The two sealing lips 411 on both sides of the dustproof sealing ring 41 can fit tightly against the stirring shaft. The sealing lips 411 are thin and elastic, and their inner diameter is smaller than that of the dustproof sealing ring 41. They can fit tightly against the stirring shaft to prevent dust from spreading to other places and to prevent bacteria from accumulating in the dust, thus effectively preventing equipment damage.
