Description

Technical Field

[0001] This invention relates to the field of silver ingot production technology, and in particular to a packaging equipment for finished silver ingots. Background Technology

[0002] Silver exists in nature in small amounts as a free element, primarily as silver compound ores. Silver is chemically stable, has low reactivity, is expensive, possesses excellent thermal and electrical conductivity, is not easily corroded by chemicals, is soft, and highly malleable. Its reflectivity is extremely high, reaching over 99%. Silver ingots require packaging and transportation during production and processing. Silver is extruded using an extrusion molding machine and then transported by packaging and conveyor systems.

[0003] During the production of silver products, packaging equipment is needed to limit their movement and prevent bending and deviation during extrusion. Existing equipment typically uses a limiting plate to directly contact the extruded silver product for packaging. However, the freshly extruded silver material is at a high temperature, and it is easy for it to adhere to the outer wall of the limiting plate during contact. At the same time, friction between the silver product and the limiting plate during extrusion can damage the silver product and reduce the usability of the packaging conveyor. Summary of the Invention

[0004] Based on the existing silver product production process, this invention proposes a finished silver ingot packaging equipment.

[0005] The silver ingot packaging equipment proposed in this invention includes a base and inner columns. Four support columns are fixedly connected to the top outer wall of the base, and the outer walls of two support columns on one side are fixedly connected to the same side limiting air plate. Air holes are opened at equal intervals on the opposite outer walls of the two side limiting air plates. An air guide hood is fixedly connected to the inner wall of each air hole. A flow divider is fixedly connected at equal intervals to the inner wall of the air guide hood, and the outer walls of multiple flow dividers are fixedly connected to the same wind resistance plate. A first flow limit hood is fixedly connected to the outer wall of the air guide hood inside the side limiting air plate. A second flow limit hood is fixedly connected to the inner wall of the first flow limit hood. The outer walls of the first flow limit hood and the air guide hood are fixedly connected to the same sealing cover. The opposite outer walls of the two support columns on one side are fixedly connected to the same support plate, and an air compressor is fixedly connected to the top outer wall of the support plate. The air supply end of the air compressor is connected to the inside of the side limiting air plate through a pipe.

[0006] Preferably, a vertical plate is fixedly connected to the top outer wall of the base, and a bottom support frame is fixedly connected to the top outer wall of the vertical plate. The inner walls on both sides of the bottom support frame are connected to rotating shafts at equal distances via bearings. A sliding roller is fixedly connected to the outer wall of each rotating shaft, and an abutting arc rod is fixedly connected to the outer wall of each sliding roller at equal distances.

[0007] Preferably, the base is fixedly connected to the top outer wall at both ends of the upright plate with guide rails, and the inner wall of each guide rail is slidably connected with a sliding block, and the top outer wall of each sliding block is fixedly connected with the same sliding plate.

[0008] Preferably, two hydraulic cylinders are fixedly connected to the top outer wall of the sliding plate, and a lifting block is fixedly connected to the top outer wall of each of the two hydraulic cylinders. The same arc-shaped limiting plate is fixedly connected to the top outer wall of the two lifting blocks.

[0009] Preferably, the top outer wall of the arc-shaped limiting plate is fixedly connected with connecting springs at equal intervals, and the top outer wall of every three adjacent connecting springs is fixedly connected with the same supporting arc plate, and the top outer wall of the supporting arc plate is fixedly connected with semi-circular rods at equal intervals.

[0010] Preferably, mounting rods are fixedly connected at equal intervals to one side of the outer wall of the inner column, and the outer walls of multiple mounting rods are fixedly connected to the same air pump, with the air pump's delivery end connected to the interior of the inner column via a pipe.

[0011] Preferably, the outer wall of the inner column is fixedly connected with mounting pieces at equal intervals, and the outer wall of each mounting piece is fixedly connected with an arc-shaped filling plate at equal intervals. Each arc-shaped filling plate has air holes at equal intervals away from the outer wall of the inner column.

[0012] Preferably, the mounting plate is fixedly connected to the outer wall at both ends of each arc-shaped filling plate with a fixing rod, and the outer wall of each fixing rod is fixedly connected to an abutment ball.

[0013] Preferably, the top outer walls of both support plates are fixedly connected to connecting frames, and the top outer wall of each connecting frame is fixedly connected to a fixed shaft. The outer wall of the fixed shaft is fixedly connected to a hollow connecting cylinder, and the outer wall of the hollow connecting cylinder is fixedly connected to hollow rotating blades at equal intervals. Each hollow rotating blade has exhaust holes at equal intervals on its outer wall.

[0014] Preferably, an exhaust fan is fixedly connected to the outer wall of the connecting frame, and a purification box is fixedly connected to the outer wall of the connecting frame near the exhaust fan. Activated carbon adsorption plates are fixedly connected at equal intervals inside the purification box. Exhaust holes are opened at equal intervals on the outer wall of the purification box facing the side limiting air plate. An exhaust pipe is fixedly connected to the exhaust end of the exhaust fan, and the other side of the exhaust pipe is fixedly connected to the inside of the hollow connecting cylinder. The exhaust end of the exhaust fan is connected to the inside of the purification box through a pipe.

[0015] The beneficial effects of this invention are as follows:

[0016] 1. Equipped with an air compressor, side limiting air plates, air guide hoods, bottom support frame, and sliding rollers, this system ensures that during silver product packaging, the bottom of the silver product contacts the contact arc rod above the sliding rollers, reducing the contact area. During extrusion, the rotating shaft on the sliding rollers rotates, changing the forward movement to sliding forward, further reducing friction damage. Simultaneously, the air compressor is activated during extrusion, directing compressed gas into the side limiting air plates. The first and second flow restrictors perform secondary and tertiary compression of the airflow, which is then discharged through the air guide hoods. The wind resistance plates and various diverter plates evenly distribute the airflow towards the silver product, ensuring both ends receive the same airflow force. This contactless packaging prevents damage during extrusion. The airflow limiting also provides cooling, accelerating the cooling and shaping of the silver product and enhancing the equipment's usability.

[0017] 2. With an internal filling cooling component, the silver product is located on the outside of the inner column during the extrusion process. When the air pump is activated, the air pump introduces external gas into each arc-shaped filling plate. The air holes on the arc-shaped filling plate rapidly cool the inner wall of the silver product, accelerating its molding process. At the same time, during the extrusion process, the abutment ball on the fixing rod supports the inner wall of the silver product, preventing internal collapse during extrusion and ensuring the integrity of the shape of the extruded silver product.

[0018] 3. Equipped with a dust collection component, during the extrusion process of the silver product, each exhaust fan is activated. The exhaust fans guide the gas around the silver product into the purification chamber through the exhaust holes on each hollow rotor. The multi-layer activated carbon adsorption plate in the purification chamber adsorbs some impurities in the gas. The exhaust port discharges the purified gas. The discharged gas is then drawn into the corresponding side limiting air plates and inner columns by the air compressor and air pump, ensuring that the gas blown onto the silver product is clean. This prevents dust in the outside air from contaminating the outer wall of the silver product during the extrusion process, ensuring the usability of the silver product.

[0019] 4. By setting up a guide rail, sliding block, sliding plate, arc-shaped limit plate, connecting spring, and supporting arc plate, the silver product is nearly molded after being cooled by both the air compressor and the air pump. After the silver product is extruded above the supporting arc plate, it compresses the supporting arc plate, and the connecting spring is compressed. As the silver product continues to be extruded, one side of the silver product drives the sliding block located below to slide on the inner wall of the sliding rail. The supporting arc plate supports one side of the silver product, preventing bending on one side and further improving the use value of the packaging equipment. Attached Figure Description

Detailed Implementation

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0030] Reference Figure 1-4The packaging equipment used in the silver product production line includes a base 1 and inner columns 28. Four support columns 11 are fixedly connected to the top outer wall of the base 1, and the outer walls of two support columns 11 located on one side are fixedly connected to the same side limiting air plate 7. Air holes are equidistantly opened on the opposite outer walls of the two side limiting air plates 7. An air guide hood 18 is fixedly connected to the inner wall of each air hole. Diverter plates 20 are equidistantly connected to the inner wall of the air guide hood 18, and the outer walls of multiple diverter plates 20 are fixedly connected to the same wind resistance plate 1. 9. A first flow restrictor 22 is fixedly connected to the outer wall of the air guide shroud 18 inside the side limiting air plate 7. A second flow restrictor 23 is fixedly connected to the inner wall of the first flow restrictor 22. The outer walls of the first flow restrictor 22 and the air guide shroud 18 are fixedly connected to the same sealing cover 21. The outer walls of the two support columns 11 on one side are fixedly connected to the same support plate 10 on opposite sides. An air compressor 14 is fixedly connected to the top outer wall of the support plate 10. The air delivery end of the air compressor 14 is connected to the inside of the side limiting air plate 7 through a pipe. By incorporating an air compressor 14, side limiting air plates 7, air guide shroud 18, bottom support frame 34, and sliding roller 38, during the packaging operation of silver products, the bottom end of the silver product contacts the abutment arc rod 40 above the sliding roller 38, thereby reducing the contact area of ​​the silver product. During the extrusion process of the silver product, the rotating shaft 35 on the sliding roller 38 is driven to rotate, changing the forward movement to sliding forward, further reducing frictional damage during the extrusion process. Simultaneously, the air compressor is started during the extrusion of the silver product. 14. The air compressor 14 introduces the compressed gas into the side limiting air plate 7. The first flow limiting hood 22 and the second flow limiting hood 23 compress the air force for a second and third time, and then discharge it through the air guide hood 18. The wind resistance plate 19 and each flow divider 20 divide the air force into multiple streams and blow them towards the silver product, so that the silver product is subjected to the same air force at both ends, and the packaging is non-contact, which avoids damage to the silver product during the extrusion process. The air force limiting also has a cooling effect, which accelerates the cooling and shaping of the silver product and improves the use value of the packaging equipment.

[0031] Reference Figure 1 , Figure 7 and Figure 8 A vertical plate 43 is fixedly connected to the top outer wall of the base 1, and a bottom support frame 34 is fixedly connected to the top outer wall of the vertical plate 43. The inner walls on both sides of the bottom support frame 34 are connected to rotating shafts 35 at equal distances via bearings. A sliding roller 38 is fixedly connected to the outer wall of each rotating shaft 35, and an abutting arc rod 40 is fixedly connected to the outer wall of each sliding roller 38 at equal distances.

[0032] In this invention, the top outer walls of the base 1 at both ends of the upright plate 43 are fixedly connected with guide rails 13, and the inner walls of the two guide rails 13 are slidably connected with sliding blocks 15, and the top outer walls of the two sliding blocks 15 are fixedly connected with the same sliding plate 12.

[0033] In this invention, two hydraulic cylinders 36 are fixedly connected to the top outer wall of the sliding plate 12, and a lifting block 42 is fixedly connected to the top outer wall of each of the two hydraulic cylinders 36. The same arc-shaped limiting plate 16 is fixedly connected to the top outer wall of the two lifting blocks 42.

[0034] In this invention, connecting springs 41 are fixedly connected at equal intervals to the top outer wall of the arc-shaped limiting plate 16, and the same supporting arc plate 39 is fixedly connected to the top outer wall of every three adjacent connecting springs 41. Semicircular rods 37 are fixedly connected at equal intervals to the top outer wall of the supporting arc plate 39. By setting up a guide rail 13, sliding block 15, sliding plate 12, arc-shaped limiting plate 16, connecting springs 41 and supporting arc plate 39, the silver product is nearly completed after being cooled by the air compressor 14 and air pump 3. After the silver product is extruded above the supporting arc plate 39, the silver product squeezes the supporting arc plate 39, and the connecting springs 41 are compressed. As the silver product continues to be extruded, one side of the silver product drives the sliding block 15 located below to slide on the inner wall of the guide rail 13. The supporting arc plate 39 supports one side of the silver product, avoiding the phenomenon of one side bending, and further improving the use value of the packaging equipment.

[0035] Reference Figure 1 and Figure 6 Mounting rods 2 are fixedly connected at equal intervals to one side of the outer wall of the inner column 28, and the outer walls of multiple mounting rods 2 are fixedly connected to the same air pump 3. The air supply end of the air pump 3 is connected to the inside of the inner column 28 through a pipe. Mounting pieces 29 are fixedly connected at equal intervals to the outer wall of the inner column 28, and arc-shaped filling plates 33 are fixedly connected at equal intervals to the outer wall of each mounting piece 29. Air holes 32 are opened at equal intervals on the outer wall of each arc-shaped filling plate 33 away from the inner column 28. Fixing rods 31 are fixedly connected to the outer walls of the mounting pieces 29 at both ends of each arc-shaped filling plate 33, and the outer walls of each fixing rod 31 are fixedly connected to... With the contact ball 30 attached and an internal filling cooling component installed, the silver product is located outside the inner column 28 during the extrusion process. The air pump 3 is activated, and the air pump 3 introduces external gas into each arc-shaped filling plate 33. The air holes 32 on the arc-shaped filling plate 33 rapidly cool the inner wall of the silver product, accelerating its molding process. At the same time, during the extrusion process of the silver product, the contact ball 30 on the fixing rod 31 supports the inner wall of the silver product, preventing internal collapse during the extrusion process and ensuring the shape integrity of the silver product after extrusion.

[0036] Reference Figure 1 and Figure 5The top outer walls of the two support plates 10 are fixedly connected to the connecting frame 17, and the top outer wall of each connecting frame 17 is fixedly connected to the fixed shaft 5. The outer wall of the fixed shaft 5 is fixedly connected to the hollow connecting cylinder 8. The outer wall of the hollow connecting cylinder 8 is fixedly connected to the hollow rotating blade 6 at equal intervals. The outer wall of each hollow rotating blade 6 is opened with exhaust holes 24 at equal intervals.

[0037] In this invention, an exhaust fan 9 is fixedly connected to the outer wall of the connecting frame 17, and a purification box 25 is fixedly connected to the outer wall of the connecting frame 17 near the exhaust fan 9. Activated carbon adsorption plates 27 are fixedly connected at equal intervals inside the purification box 25. Exhaust holes 26 are opened at equal intervals on the outer wall of the purification box 25 facing the side limiting air plate 7. An exhaust pipe 4 is fixedly connected to the exhaust end of the exhaust fan 9, and the other side of the exhaust pipe 4 is fixedly connected to the inside of the hollow connecting cylinder 8. The exhaust end of the exhaust fan 9 is connected to the inside of the purification box 25 through a pipe. By setting up a dust collection component, the dust collection device is activated during the extrusion of the silver product. Each exhaust fan 9 draws air from the vicinity of the silver product into the purification box 25 through the exhaust holes 24 on each hollow rotating blade 6. The multi-layer activated carbon adsorption plate 27 in the purification box 25 adsorbs some impurities in the air, and the exhaust hole 26 discharges the purified air. The discharged air is then drawn into the corresponding side limiting air plate 7 and inner column 28 by the air compressor 14 and air pump 3, ensuring that the air blown onto the silver product is clean. This prevents dust in the outside air from contaminating the outer wall of the silver product during the extrusion process, thus ensuring the product's usability.

[0038] In use, the inner column 28 is installed in the middle of the silver product extrusion end of the extruder. During the silver product extrusion process, each exhaust fan 9 is activated. The exhaust fans 9 guide the gas around the silver product into the purification box 25 through the exhaust holes 24 on each hollow rotating blade 6. Some impurities in the gas are adsorbed by the multi-layer activated carbon adsorption plate 27 in the purification box 25. The purified gas is discharged through the exhaust hole 26. The discharged gas is drawn into the corresponding side limiting air plate 7 and inner column 28 by the air compressor 14 and air pump 3 to ensure that the gas blown towards the silver product is clean gas. During the process, to prevent dust in the outside air from contaminating the outer wall of the silver product, the bottom end of the silver product contacts the contact arc rod 40 above the sliding roller 38 during the silver product packaging operation, thereby reducing the contact area of ​​the silver product. During the extrusion of the silver product, the rotating shaft 35 on the sliding roller 38 is rotated, changing the forward movement to sliding forward, further reducing frictional damage during the extrusion process. At the same time, during the extrusion of the silver product, the air compressor 14 is started, and the air compressor 14 introduces compressed gas into the side limiting air plate 7. The first flow limiting hood 22 and the second flow limiting hood 23 control the airflow. The air undergoes secondary and tertiary compression, and is then discharged through the air guide shroud 18. The air resistance plate 19 and various diverter plates 20 evenly distribute the airflow into multiple streams, blowing it towards the silver product. This ensures that both ends of the silver product receive the same airflow, preventing contact packaging and avoiding damage during extrusion. The airflow also limits the airflow while simultaneously cooling the product, accelerating its cooling and shaping process. The air pump 3 is activated, drawing external air into the various arc-shaped filler plates 33. Through the air holes 32 on the arc-shaped filler plates 33, the inner wall of the silver product is rapidly cooled, accelerating its shaping process. Simultaneously, the extrusion process of the silver product... In the process, the contact ball 30 on the fixed rod 31 supports the inner wall of the silver product, preventing it from collapsing during extrusion. When the silver product is extruded to the support arc plate 39, it compresses the support arc plate 39, compressing the connecting spring 41. As the silver product continues to be extruded, one side of the silver product drives the sliding block 15 located below to slide on the inner wall of the guide rail 13. The support arc plate 39 supports one side of the silver product, preventing one side from bending. After extrusion, the extruded silver product is collected and the operation is repeated.
