Description

Technical Field

[0001] This utility model relates to the field of capsule processing technology, specifically to a hollow capsule polishing device. Background Technology

[0002] Empty capsules are a type of packaging material widely used in the pharmaceutical and health product industries to contain various drugs or nutritional components. During the processing of empty capsules, a hollow capsule polishing device is used to remove dust, debris, and other impurities from the surface of the capsules through physical polishing, improving their surface smoothness, cleanliness, and appearance quality, so that they meet the quality standards and usage requirements for pharmaceutical or health product production.

[0003] In existing hollow capsule polishing devices, hollow capsules are generally poured directly into the hopper and then moved into the polishing cylinder by a rotating auger conveyor roller. At this time, the capsules move in a circular spiral motion along the tube wall of the polishing cylinder. The capsules polish the outer shell through continuous friction with the cloth layer and the polishing cylinder wall. However, since hollow capsules are usually slender cylinders with a certain degree of elasticity and flexibility, when a large number of capsules in the hopper directly flow into the polishing cylinder, they may squeeze and entangle with each other, and pile up together in an irregular manner, which can easily cause congestion at the inlet and blockage. At the same time, dust from the hopper will also fly outward when the material is discharged.

[0004] Therefore, a hollow capsule polishing device is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a hollow capsule polishing device in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] A hollow capsule polishing device includes a base and a polishing cylinder. A hopper is fixedly inserted into the surface of the polishing cylinder, and an opening assembly is provided inside the hopper. A closing cover is hinged to the inner wall of the opening assembly. A driving assembly for uniformly feeding hollow capsules is provided on the inner wall of the opening assembly. An auger rod is fixedly connected to the surface of the driving assembly. A polishing assembly for polishing hollow capsules is provided on the surface and inside of the polishing cylinder. A fiber cloth layer is provided on the surface of the polishing assembly. A collection assembly for collecting polishing impurities is provided on the top surface of the base. A dust outlet is opened through the surface of the polishing cylinder. An extraction assembly for collecting polishing impurities is provided on the surface of the collection assembly and the inner wall of the dust outlet. A support leg is fixedly connected to the surface of the polishing cylinder and is fixedly connected to the base.

[0008] Furthermore, the opening assembly includes a material placement trough, the top surface of the hopper is provided with a material placement trough, the inner wall of the material placement trough is provided with an installation groove, and the closing cover is hinged to the inner wall of the installation groove, and the bottom surface of the inner wall of the material placement trough is provided with a drop groove.

[0009] Furthermore, the drive assembly includes a mounting block, the inner wall of the material feeding trough is fixedly connected to the mounting block, the bottom surface of the mounting block is fixedly connected to a servo motor, the output end of the servo motor is fixedly connected to a connecting rod, and the auger rod is fixedly connected to the bottom end of the connecting rod.

[0010] Furthermore, the polishing assembly includes a motor, the side of the polishing cylinder is fixedly connected to the motor, the output end of the motor is fixedly connected to a rotating rod, and the rotating rod is rotatably connected to the polishing cylinder. An auger conveyor roller is fixedly sleeved on the surface of the rotating rod, and a fiber cloth layer is disposed on the surface of the auger conveyor roller.

[0011] Furthermore, the collection assembly includes a collection box, which is fixedly connected to the top surface of the base. A door is hinged to the surface of the collection box, and a ventilation filter is provided on the surface of the door. A collection compartment is provided on the inner wall of the collection box.

[0012] Furthermore, the extraction component includes an extraction pump, the top surface of the collection box is fixedly connected to the extraction pump, and the air outlet of the extraction pump is connected to the collection box through a pipe. An extraction frame is fixedly inserted into the inner wall of the dust outlet, and the extraction frame is connected to the air extraction end of the extraction pump through a pipe. A metal filter screen is fixedly inserted into the inner wall of the dust outlet.

[0013] The beneficial effects of this utility model are as follows:

[0014] In this invention, when polishing hollow capsules, the hollow capsules to be polished are placed into the material trough and piled up. Before polishing, the closing cap is closed. At this time, through the setting of the internal drive component and auger rod in the hopper, the hollow capsules can be evenly conveyed. By adjusting the rotation speed of the auger rod, the capsules can be slowly and evenly conveyed into the polishing cylinder. The polishing component on the polishing cylinder allows the hollow capsules to be polished through continuous friction between the fiber cloth layer and the inner wall of the polishing cylinder. When the capsules pass through the dust outlet, the negative pressure generated by the extraction component and the metal filter screen block the hollow capsules, and the dust and impurities can be sucked into the collection component and accumulated in the collection box. At this time, the hollow capsules can be slowly and evenly conveyed into the polishing cylinder for polishing treatment, avoiding the problem of capsules accumulating and clogging at the inlet. At the same time, with the use of the closing cap, the capsules are slowly conveyed into the polishing cylinder, so that the dust will not fly out through the top opening of the hopper.

[0025] like Figure 1-5As shown, a hollow capsule polishing device includes a base 1 and a polishing cylinder 2. A hopper 3 is fixedly inserted into the surface of the polishing cylinder 2. An opening assembly 4 is provided inside the hopper 3. A closing cover 5 is hinged to the inner wall of the opening assembly 4. A driving assembly 6 for uniformly feeding hollow capsules is provided on the inner wall of the opening assembly 4. An auger rod 7 is fixedly connected to the surface of the driving assembly 6. A polishing assembly 8 for polishing hollow capsules is provided on the surface and inside of the polishing cylinder 2. A fiber cloth layer 9 is provided on the surface of the polishing assembly 8. A collection assembly 10 for collecting polishing impurities is provided on the top surface of the base 1. A dust outlet 11 is provided through the surface of the polishing cylinder 2. The surface of the collection assembly 10 is connected to the dust outlet 11. The inner wall of the dust inlet 11 is equipped with an extraction component 12 for collecting polishing impurities. A support leg 13 is fixedly connected to the surface of the polishing cylinder 2, and the support leg 13 is fixedly connected to the base 1. Specifically, in this hollow capsule polishing device, the fiber cloth layer 9 can be made from organic dicarboxylic acids and diols through chemical condensation, giving it high strength and good wear resistance. During hollow capsule polishing, the fiber cloth layer 9 can withstand high polishing pressure and friction cycles, making it less prone to wear and extending its service life. When polishing the hollow capsule, the hopper 3, through the opening component 4, allows the closed cover 5 to be flipped, allowing the material to be polished to be placed inside the opening component 4. Hollow capsules are placed in the hopper 3. Before polishing, the closed cover 5 is flipped over, closing the top opening of the hopper 3. At this time, the drive assembly 6 and the auger rod 7 inside the hopper 3 rotate, allowing the hollow capsules in the hopper 3 to be evenly and slowly conveyed into the polishing cylinder 2. The polishing cylinder 2 is equipped with a polishing assembly 8. As the hollow capsules fall into the polishing cylinder 2 and are spirally conveyed by the polishing assembly 8, they are polished through continuous friction between the fiber cloth layer 9 and the inner wall of the polishing cylinder 2. When the capsules are conveyed in the polishing cylinder 2, as they pass through the dust outlet 11, the dust is collected by the collection assembly 10 and the extraction assembly 12. The negative pressure generated by the extraction component 12 allows dust and impurities on the capsule surface to be drawn into the collection component 10 for collection. The support leg 13 supports the polishing cylinder 2. When the capsule falls into the polishing cylinder 2, the opening of the hopper 3 is closed, preventing dust from flying upwards. At the same time, the capsule is slowly and evenly conveyed into the polishing cylinder 2, which also reduces dust flying. The hollow capsule can be slowly and evenly conveyed into the polishing cylinder 2 for polishing, avoiding the problem of capsules accumulating and clogging at the inlet. With the use of the closing cover 5, the capsule is slowly conveyed into the polishing cylinder 2, preventing dust from flying out through the top opening of the hopper 3.

[0026] like Figure 4As shown, the opening assembly 4 includes a material placement trough 401. The top surface of the hopper 3 has a material placement trough 401, and the inner wall of the material placement trough 401 has an installation groove 402. The closing cover 5 is hinged to the inner wall of the installation groove 402. The bottom surface of the inner wall of the material placement trough 401 has a drop groove 403. Specifically, the opening assembly 4 is set inside the hopper 3 to facilitate the feeding process of the hollow capsule. The material placement trough 401 is set to temporarily place the hollow capsule to be polished. The installation groove 402 is set to connect the closing cover 5 to the hopper 3. The closing cover 5 allows the top opening of the hopper 3 to be closed during polishing. The drop groove 403, in conjunction with the use of the drive assembly 6 and the auger rod 7, allows the hollow capsule in the material placement trough 401 to be slowly and evenly transported to the polishing cylinder 2 for polishing.

[0027] like Figure 2 , Figure 4 As shown, the drive assembly 6 includes a mounting block 601. The mounting block 601 is fixedly connected to the inner wall of the material trough 401. A servo motor 602 is fixedly connected to the bottom surface of the mounting block 601. A connecting rod 603 is fixedly connected to the output end of the servo motor 602, and the auger rod 7 is fixedly connected to the bottom end of the connecting rod 603. Specifically, the drive assembly 6 is configured to drive the auger rod 7 to rotate, so that the hollow capsule in the material trough 401 can be slowly and evenly conveyed into the polishing cylinder 2. The mounting block 601 installs and fixes the servo motor 602 in the hopper 3. During polishing, the servo motor 602... The output of the servo motor 602 drives the connecting rod 603 to rotate, and the connecting rod 603 drives the auger rod 7 to rotate. The rotating auger rod 7 allows the hollow capsules to pass evenly through the drop groove 403 into the polishing cylinder 2. At the same time, by adjusting the speed of the servo motor 602, the capsules can be slowly conveyed. At this time, the capsules are less likely to be squeezed and deformed at the inlet, thus preventing the hollow capsules from clogging and accumulating at the inlet. In addition, with the use of the closing cover 5, the dust is not easily scattered, and the dust will not drift out through the opening of the hopper 3.

[0028] like Figure 1 , Figure 2 , Figure 5As shown, the polishing assembly 8 includes a motor 801. The motor 801 is fixedly connected to the side of the polishing cylinder 2. The output end of the motor 801 is fixedly connected to a rotating rod 802, and the rotating rod 802 is rotatably connected to the polishing cylinder 2. An auger conveyor roller 803 is fixedly sleeved on the surface of the rotating rod 802, and a fiber cloth layer 9 is disposed on the surface of the auger conveyor roller 803. Specifically, the polishing assembly 8 is configured such that the hollow capsules are spirally conveyed in the polishing cylinder 2, so that the hollow capsules can be polished by friction between the fiber cloth layer 9 and the inner wall of the polishing cylinder 2. The output end of the motor 801 drives the rotating rod 802 to rotate, and the rotating rod 802 drives the auger conveyor roller 803 to rotate. The auger conveyor roller 803 allows the hollow capsules entering the polishing cylinder 2 to be spirally conveyed.

[0029] like Figure 1 , Figure 2 As shown, the collection component 10 includes a collection box 1001. The collection box 1001 is fixedly connected to the top surface of the base 1. A door 1002 is hinged to the surface of the collection box 1001. A ventilation filter 1003 is provided on the surface of the door 1002. A collection box 1004 is provided on the inner wall of the collection box 1001. Specifically, the collection component 10 is used in conjunction with the extraction component 12. During polishing, dust and impurities on the surface of the capsule can be collected. Through the negative pressure generated by the extraction component 12, the dust enters the collection box 1001. The ventilation filter 1003 makes the air pressure in the collection box 1001 synchronize with the outside air pressure. The dust and impurities entering the collection box 1001 accumulate in the collection box 1004. By opening the door 1002, the collection box 1004 can be taken out for centralized processing of the collected dust.

[0030] like Figure 2 , Figure 3 As shown, the extraction component 12 includes an extraction pump 1201. The extraction pump 1201 is fixedly connected to the top surface of the collection box 1001, and the air outlet of the extraction pump 1201 is connected to the collection box 1001 through a pipe. An extraction frame 1202 is fixedly inserted into the inner wall of the dust outlet 11, and the extraction frame 1202 is connected to the air extraction end of the extraction pump 1201 through a pipe. A metal filter screen 1203 is fixedly inserted into the inner wall of the dust outlet 11. Specifically, the extraction component 12 is configured such that when the capsule passes through the dust outlet 11, the negative pressure generated by the extraction component 12 sucks up the dust and impurities on the surface of the capsule. The extraction pump 1201 runs, and the air extraction end of the extraction pump 1201 is connected through a pipe. The extraction frame 1202 can extract the dust and impurities, and the metal filter screen 1203 can block the hollow capsule. The extracted dust and impurities will accumulate in the collection component 10.

[0031] In summary, this hollow capsule polishing device, when polishing hollow capsules, first flips the closed cover 5 on the mounting groove 402, opening the top opening of the hopper 3. At this point, the hollow capsules to be polished can be placed into the material storage trough 401 for accumulation. Before polishing, the closed cover 5 is flipped again, closing the opening of the hopper 3. Then, through the internal drive assembly 6 and auger rod 7 of the hopper 3, the output of the servo motor 602 drives the connecting rod 603 to rotate, which in turn drives the auger rod 7. The rotating auger rod 7 then allows the hollow capsules in the material storage trough 401 to be transported to the polishing cylinder 2 through the drop trough 403. The hollow capsules are then evenly transported. The rotation speed of the auger rod 7 can be adjusted... This allows the capsules to be slowly and evenly conveyed into the polishing cylinder 2. The polishing component 8 is set on the polishing cylinder 2. The motor 801 drives the rotating rod 802 to rotate, and the rotating rod 802 drives the auger conveying roller 803 to rotate. The auger conveying roller 803 causes the hollow capsules entering the polishing cylinder 2 to be spirally conveyed. The hollow capsules are polished by the continuous friction between the fiber cloth layer 9 and the inner wall of the polishing cylinder 2. When the capsules pass through the dust outlet 11, the negative pressure generated by the extraction component 12 and the metal filter 1203 block the hollow capsules. Dust and impurities can be sucked into the collection component 10. The dust accumulates in the collection box 1004. The collection box 1004 can be taken out by opening the box door 1002, and the collected dust can be centrally processed.
