Description

Technical Field

[0001] This invention belongs to the field of aluminum cap production technology, and more specifically, relates to a screening and cleaning device. Background Technology

[0002] Pharmaceutical aluminum caps are widely used in the sealing packaging of medicines and health products. During the stamping process of aluminum caps, some waste is generated, requiring sorting of the waste and aluminum caps, followed by cleaning of the sorted caps. To save labor, a drum screen is typically used to separate the waste and caps. The waste and caps are placed inside the drum screen, and as the drum rotates, the waste falls out. Since the drum screen does not have a cleaning function, the sorted caps also need to be collected and cleaned, making the process relatively cumbersome. Summary of the Invention

[0003] The purpose of this invention is to provide a screening and cleaning device, which aims to solve the problem that when screening waste materials and aluminum caps using a drum screen, since the drum screen does not have a cleaning function, it is still necessary to collect the sorted aluminum caps and clean them.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a screening and cleaning device is provided, including a drum screen, wherein the drum screen includes a screen cylinder, the rotating axis of the screen cylinder is set at an angle to the horizontal plane, and the screening and cleaning device further includes a cleaning tank. The cleaning tank is sleeved outside the lower end of the screen cylinder and fits against the lower end surface of the screen cylinder, and the bottom wall of the cleaning tank is provided with a liquid outlet hole.

[0005] In one possible implementation, the screen cylinder has multiple screening tubes evenly arranged around the rotation axis of the screen cylinder. The length direction of the screening tubes is parallel to the rotation axis of the screen cylinder. The lower end of each screening tube is closed. The side wall of each screening tube is provided with several rinsing holes. The cleaning tank is used to fit around the lower end of the multiple screening tubes and fits against the lower end face of the screening tubes, so that the rinsing holes are located inside the cleaning tank and face the rotation axis of the screen cylinder.

[0006] In one possible implementation, the screening and washing device further includes a collection tank and a base. The opening of the collection tank faces upward. The base is located inside the collection tank and fixed to the bottom wall of the collection tank. The drum screen is mounted on the base, and the collection tank is capable of receiving liquid flowing out of the outlet hole.

[0007] In one possible implementation, a gap exists between the base and the sidewall of the collection tank, and the screening and washing device further includes a filter screen. The filter screen is laid within the gap between the base and the sidewall of the collection tank and is fixedly connected to both the collection tank and the base. The sidewall of the collection tank has an outflow hole located below the filter screen.

[0008] In one possible implementation, the screening and washing device further includes a main body, a first annular plate, and a water inlet pipe. The main body has a circular annular structure and is coaxially arranged with the rolling axis of the screen cylinder. The main body has an annular cavity coaxially arranged with it, with one axial end of the annular cavity being an open end. The main body is fixedly mounted on the base. The first annular plate is coaxially arranged with the main body and rotatably passes through the open end of the annular cavity. One end of the water inlet pipe is fixedly connected to the main body and communicates with the annular cavity. The screening pipe penetrates the first annular plate so that its upper end communicates with the inside of the annular cavity, and the screening pipe is fixedly connected to the first annular plate.

[0009] In one possible implementation, the screening and washing device further includes a sealing gasket. The sealing gasket mates with the first annular plate and is fixedly fitted to the end face of the first annular plate facing into the annular cavity.

[0010] In one possible implementation, the screening and washing device further includes a second annular plate. The second annular plate is slidably sleeved around the plurality of screening tubes and fits against the end face of the washing tank opening. The second annular plate is detachably connected to the washing tank. A gap exists between the sidewall of the washing tank and the plurality of screening tubes.

[0011] In one possible implementation, the screening and cleaning device further includes a retaining ring and connecting components. The retaining ring is sleeved and fixed outside the cleaning tank. Multiple connecting components are included, each comprising a connecting shaft and connecting bolts. The connecting shaft is parallel to the screening tube and includes a first section with a larger diameter and a second section with a smaller diameter. The end face of the connecting shaft on the second section has a threaded hole, and the second section slides through the retaining ring. The thread of the connecting bolt passes through the second annular plate and is threaded into the threaded hole, so that the head of the connecting bolt engages with the first section to clamp the second annular plate and the retaining ring.

[0012] In one possible implementation, the base has an upwardly protruding portion, and the screening and cleaning device further includes a fixing member, a connecting member, a hydraulic cylinder, a drive shaft, a guide shaft, a drive motor, and two meshing gears. The fixing member is fixedly fitted to the end faces of all the connecting shafts located on the first segment. The connecting member is slidably sleeved on all the first segments. The cylinder body of the hydraulic cylinder is fixedly connected to the connecting member, and the piston rod of the hydraulic cylinder is axially extendable along the connecting shaft and fixedly connected to the fixing member. The drive shaft is horizontally arranged and perpendicular to the connecting shaft, and the drive shaft is rotatably inserted into the protrusion. There are two guide shafts, which are parallel to the connecting shaft and slidably inserted into the fixing member. One end of the guide shaft is fixedly connected to the connecting member, and the other end is fixedly connected to the drive shaft. The two guide shafts are respectively located on both sides of the protrusion and are both fitted to the protrusion. The drive motor is fixed to the base. The two meshing gears are respectively sleeved and fixed on the drive shaft and the output shaft of the drive motor. When the second annular plate slides away from the multiple screening tubes, the rotation of the drive shaft causes the opening of the cleaning tank to face upwards.

[0013] In one possible implementation, the screening and cleaning device further includes a U-shaped component, an air inlet pipe, and a purge nozzle. The U-shaped component is fitted downwards around the collection trough and fixedly connected to it. The air inlet pipe is vertically arranged, penetrating the top wall of the U-shaped component and fixedly connected to it. The purge nozzle is fixed at the lower end of the air inlet pipe. When the drive shaft rotates, causing the opening of the collection trough to face upwards, the collection trough is located directly below the purge nozzle.

[0014] In this embodiment, aluminum caps and waste materials are placed inside a screen cylinder. As the screen cylinder rotates, the waste materials fall from the screen cylinder, while the aluminum caps slide into a cleaning tank. Cleaning fluid is injected into the cleaning tank, and the aluminum caps are cleaned by the rotation of the screen cylinder. This avoids the problem of needing to collect and clean the sorted aluminum caps when using a drum screen to separate waste materials and aluminum caps, as the drum screen does not have a cleaning function.

[0030] Please refer to the following: Figure 1 , Figure 5 and Figure 7 The screening and cleaning device provided by the present invention will now be described. The screening and cleaning device includes a drum screen 1, which includes a screen cylinder 11. The rolling axis of the screen cylinder 11 is set at an angle to the horizontal plane. The screening and cleaning device also includes a cleaning tank 2. The cleaning tank 2 is sleeved outside the lower end of the screen cylinder 11 and fits against the lower end face of the screen cylinder 11. The bottom wall of the cleaning tank 2 is provided with a liquid outlet hole 21.

[0031] Compared with the prior art, the screening and cleaning device provided by this invention places aluminum caps and waste materials into a screen cylinder 11. During the rotation of the screen cylinder 11, the waste materials fall from the screen cylinder 11, while the aluminum caps slide into the cleaning tank 2. Cleaning liquid is injected into the cleaning tank 2, and the aluminum caps are cleaned by the rotation of the screen cylinder 11. This avoids the problem of collecting and cleaning the sorted aluminum caps when screening waste materials and aluminum caps using a drum screen 1, since the drum screen 1 does not have a cleaning function.

[0032] In this embodiment, the liquid outlet 21 is located at the lowest point of the cleaning tank 2, and the waste liquid from cleaning the aluminum cover flows out from the liquid outlet 21.

[0033] In some embodiments, see Figure 5 , Figure 7 and Figure 8 The screen cylinder 11 has multiple screening tubes 111, which are evenly arranged around the rotation axis of the screen cylinder 11. The length direction of the screening tubes 111 is parallel to the rotation axis of the screen cylinder 11. The lower end of the screening tubes 111 is closed. The side wall of the screening tubes 111 is provided with several rinsing holes 1111. The cleaning tank 2 is used to fit around the lower end of the multiple screening tubes 111 and fits against the lower end face of the screening tubes 111, so that the rinsing holes 1111 are located inside the cleaning tank 2 and the rinsing holes 1111 face the rotation axis of the screen cylinder 11. An aluminum cap and waste material are placed between multiple screening tubes 111. As the screening cylinder 11 rotates, the waste material falls through the gaps between the screening tubes 111, while the aluminum cap slides into the cleaning tank 2. At this time, the aluminum cap is also positioned inside the multiple screening tubes 111. Cleaning liquid is injected into the screening tubes 111 through the upper end of the screening tubes 111, and the cleaning liquid is sprayed out through the flushing holes 1111, thereby flushing and cleaning the aluminum cap between the multiple screening tubes 111. In this embodiment, the cleaning tank 2 is sleeved outside the lower end of the multiple screening tubes 111 and fits against the lower end surface of the screening tubes 111, that is, it is sleeved outside the lower end of the screening cylinder 11 and fits against the lower end surface of the screening cylinder 11.

[0034] In some embodiments, see Figure 1 and Figure 5 The screening and cleaning device also includes a collection tank 3 and a base 4. The opening of the collection tank 3 faces upward. The base 4 is located inside the collection tank 3 and fixed to the bottom wall of the collection tank 3. The drum screen 1 is installed on the base 4, and the collection tank 3 can collect the liquid flowing out of the liquid outlet 21. The collection tank 3 can collect the waste material screened by the drum screen 1 and the waste liquid flowing out of the liquid outlet 21.

[0035] In some embodiments, see Figure 1 and Figure 5The base 4 and the side wall of the collection tank 3 have a gap, and the screening and washing device also includes a filter screen 5. The filter screen 5 is laid in the gap between the base 4 and the side wall of the collection tank 3 and is fixedly connected to both the collection tank 3 and the base 4. The side wall of the collection tank 3 is provided with an outlet hole 31, which is located below the filter screen 5. The waste liquid flowing out of the outlet hole 21 falls after being filtered by the filter screen 5 and then flows out from the outlet hole 31. In this embodiment, the liquid flowing out of the outlet hole 31 can be collected and then processed in the next step.

[0036] In some embodiments, see Figure 1 , Figure 5 and Figure 6 The screening and cleaning device also includes a main body 6, a first annular plate 7, and a water inlet pipe 8. The main body 6 has a circular structure and is coaxially arranged with the rolling axis of the screen cylinder 11. The main body 6 has an annular cavity 61 coaxially arranged with it, and one end of the annular cavity 61 is open in the axial direction. The main body 6 is fixedly mounted on the base 4. The first annular plate 7 is coaxially arranged with the main body 6 and rotatably passes through the open end of the annular cavity 61. One end of the water inlet pipe 8 is fixedly connected to the main body 6 and communicates with the annular cavity 61. The screening pipe 111 penetrates the first annular plate 7 so that the upper end of the screening pipe 111 communicates with the inside of the annular cavity 61, and the screening pipe 111 is fixedly connected to the first annular plate 7. In this way, the first annular plate 7 can rotate with the screen cylinder 11. Waste materials and aluminum caps are placed between multiple screening pipes 111 through the main body 6 and the first annular plate 7. The cleaning liquid is injected into the annular cavity 61 through the water inlet pipe 8, and then the cleaning liquid flows into multiple screening pipes 111.

[0037] In some embodiments, see Figure 5 and Figure 6 The screening and cleaning device also includes a sealing gasket 9. The sealing gasket 9 matches the first annular plate 7 and is fixedly attached to the end face of the first annular plate 7 facing the annular cavity 61. The sealing gasket 9 ensures a seal between the main body 6 and the first annular plate 7. In this embodiment, the screening tube 111 penetrates the sealing gasket 9.

[0038] In some embodiments, see Figure 5 The screening and cleaning device also includes a second annular plate 10. The second annular plate 10 is slidably sleeved around the multiple screening tubes 111 and fits against the end face of the opening of the cleaning tank 2. The second annular plate 10 is detachably connected to the cleaning tank 2. A gap exists between the side wall of the cleaning tank 2 and the multiple screening tubes 111. Thus, after cleaning, the second annular plate 10 slides away from the multiple screening tubes 111, and the aluminum caps between the multiple screening tubes 111 slide into the cleaning tank 2. The second annular plate 10 prevents the aluminum caps from falling out of the cleaning tank 2. Then, the connection between the second annular plate 10 and the cleaning tank 2 is disconnected, making it easy to remove the aluminum caps from the cleaning tank 2.

[0039] In some embodiments, see Figure 2 The screening and cleaning device also includes a retaining ring 110 and a connecting assembly 120. The retaining ring 110 is sleeved and fixed to the outside of the cleaning tank 2. There are multiple connecting assemblies 120, each including a connecting shaft 1201 and a connecting bolt 1202. The connecting shaft 1201 is parallel to the screening tube 111 and includes a first section 12011 with a larger diameter and a second section 12012 with a smaller diameter. The end face of the connecting shaft 1201 on the second section 12012 is provided with a threaded hole, and the second section 12012 slides through the retaining ring 110. The bolt of the connecting bolt 1202 passes through the second annular plate 10 and is threaded into the threaded hole, so that the head of the connecting bolt 1202 cooperates with the first section 12011 to clamp the second annular plate 10 and the retaining ring 110, thereby fixing the second annular plate 10 to the cleaning tank 2 together. When the threaded connection between the bolt 1202 and the threaded hole is disconnected, the connection between the second annular plate 10 and the cleaning tank 2 is also disconnected.

[0040] In some embodiments, see Figure 1 and Figure 3The base 4 has an upwardly protruding protrusion 41. The screening and cleaning device also includes a fixing member 130, a connecting member 140, a hydraulic cylinder 150, a drive shaft 160, a guide shaft 170, a drive motor 180, and two meshing gears 190. The fixing member 130 is fixedly fitted to the end faces of all the connecting shafts 1201 on the first section 12011. The connecting member 140 is slidably sleeved on all the first sections 12011. The cylinder body of the hydraulic cylinder 150 is fixedly connected to the connecting member 140, and the piston rod of the hydraulic cylinder 150 can extend and retract along the axial direction of the connecting shaft 1201 and is fixedly connected to the fixing member 130. The drive shaft 160 is horizontally arranged and perpendicular to the connecting shaft 1201, and the drive shaft 160 is rotatably inserted into the protrusion 41. Two guide shafts 170 are provided, parallel to the connecting shaft 1201 and slidably inserted within the fixing member 130. One end of each guide shaft 170 is fixedly connected to the connecting member 140, and the other end is fixedly connected to the drive shaft 160. The two guide shafts 170 are located on both sides of the protrusion 41 and are in contact with it. The drive motor 180 is fixedly mounted on the base 4. Two meshing gears 190 are respectively sleeved and fixed on the output shafts of the drive shaft 160 and the drive motor 180. When the second annular plate 10 slides away from the multiple screening tubes 111, the rotation of the drive shaft 160 causes the opening of the cleaning tank 2 to face upwards. The protrusion 41 limits the movement of the two guide shafts 170 along its axial direction, thereby rotatably connecting the drive shaft 160 and the protrusion 41 together. The extension and retraction of the piston rod of the hydraulic cylinder 150 can be converted into the sliding of the connecting shaft 1201 through the fixing member 130, thereby driving the second annular plate 10 to slide away from the multiple screening tubes 111. Then the output shaft of the drive motor 180 drives the drive shaft 160 to rotate through two meshing gears 190 until the opening of the cleaning tank 2 faces upward, and then the aluminum cover in the cleaning tank 2 is dried.

[0041] In some embodiments, see Figure 1 and Figure 4 The screening and cleaning device further includes a U-shaped component 20, an air inlet pipe 210, and a purging nozzle 220. The U-shaped component 20 is fitted downwards around the collection tank 3 and is fixedly connected to the collection tank 3. The air inlet pipe 210 is vertically arranged, penetrating the top wall of the U-shaped component 20 and being fixedly connected to the U-shaped component 20. The purging nozzle 220 is fixedly located at the lower end of the air inlet pipe 210. When the drive shaft 160 rotates, causing the opening of the collection tank 3 to face upwards, the collection tank 3 is located directly below the purging nozzle 220. At this time, the connection between the second annular plate 10 and the cleaning tank 2 is disconnected, and the upper end of the air inlet pipe 210 is connected to an air source. The gas supplied by the air source is sprayed downwards through the nozzle, thereby accelerating the drying of the aluminum cap inside the cleaning tank 2. In this embodiment, the air source can be a hot air blower.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
