Description

Technical Field

[0001] The utility model relates to the field of mechanical equipment, particularly to the field of steel ball conveying equipment, and in particular to an open steel ball spiral fast-drop device. Background Art

[0002] During steel ball production, after forging and forming, the balls need to be sorted and processed according to production and heat treatment process requirements. Forged balls require transportation, collection, and sorting. During this transportation process, due to the height differences between equipment, ball conveyors are often used. For equipment with larger height differences, spiral conveyors are often used. These conveyors effectively utilize the three-dimensional space, reducing horizontal floor space, making the structure more compact, improving space efficiency, and ensuring smooth and stable ball conveying.

[0003] However, most spiral ballways used to transport steel balls currently have closed structures, which can protect the steel balls from external environmental contamination and maintain their temperature. However, as the steel balls roll downward along the spiral ballway, the inner wall of the spiral ballway wears out, causing the steel balls to frequently get stuck, affecting the smoothness of the steel ball transportation. When a steel ball gets stuck in the spiral ballway, due to its closed structure, the operator needs to cut its outer wall to create an operating window for unblocking the stuck steel ball. During the unblocking process, the steel balls are at high temperatures, which can easily cause burns and scalds to the operator, posing a safety hazard. Furthermore, during the stuck process, the temperature of the steel balls will drop, making them not meet the processing requirements, requiring subsequent secondary heating, resulting in increased energy costs and increased production costs. After unblocking, the cut operating window needs to be welded closed. Cutting and welding the spiral ballway are complex and tedious operations, resulting in a decrease in the transportation efficiency of the steel balls and affecting the production efficiency of the steel balls. In addition, the repair of the spiral ball track will lead to uneven surface of the ball track, which will affect the smooth transportation of the steel balls and aggravate the occurrence of the jamming phenomenon. Utility Model Content

[0004] To address the technical problem of steel balls being easily stuck in closed spiral ballways, the utility model provides an open spiral steel ball descent device. An electromagnet built into the center of the spiral ballway attracts and guides steel balls that roll into the ballway, preventing them from getting stuck. Furthermore, the open structure of the spiral ballway and the observation window on its outer wall facilitate rapid unblocking of the steel balls, improving smoothness of steel ball transport and ensuring production efficiency.

[0005] The technical solution adopted by the utility model is: to provide an open steel ball spiral descent device, including a ball entry channel and a ball exit channel, and also including an open spiral ball channel, the top and bottom of the spiral ball channel are respectively connected to the ball entry channel and the ball exit channel, and the inner side wall of the spiral ball channel is fixedly sleeved with a hollow shaft, the two ends of the hollow shaft respectively protrude from the top and bottom of the spiral ball channel, a ceramic sleeve is slidably inserted in the hollow shaft, and an electromagnet is assembled in the ceramic sleeve; a plurality of observation windows are evenly arranged on the outer side wall of the spiral ball channel.

[0006] The spiral ball channel connected with the ball channel is an open structure, thereby releasing its top space, reducing interference with the rolling of the steel ball, and ensuring the smooth rolling of the steel ball. The two ends of the hollow shaft supporting the spiral ball channel protrude from the top and bottom of the spiral ball channel respectively, providing sufficient installation space for the spiral ball channel, ensuring safety and reliability of use. The electromagnet built into the hollow shaft adsorbs the steel ball after the steel ball enters the spiral ball channel, so that the steel balls are all attached to the inner side of the spiral ball channel, thereby guiding the steel balls so that they are more orderly after entering the spiral ball channel, avoiding accumulation and blockage of the steel balls. Since the adsorption strength of the electromagnet is lower than the gravity exerted on the steel balls, the rolling of the steel balls is not interfered with, and the steel balls are not easy to be blocked, thereby improving the conveying efficiency of the steel balls. The steel balls have a certain temperature after forging, and the temperature will be conducted from the spiral ball channel to the hollow shaft. Therefore, the electromagnet is wrapped by a ceramic sleeve and built into the hollow shaft, which reduces the damage to the electromagnet caused by temperature and is safer and more reliable to use.

[0007] To further optimize this technical solution, the spiral ball track includes a spiral base film arranged on the outer wall of the hollow shaft, the inner wall of the spiral base film is welded and fixed to the outer wall of the hollow shaft, and an outer baffle is welded and fixed to the outer wall of the spiral base film, the outer baffle matches the shape of the spiral base film, and the observation windows are evenly arranged on the outer baffle.

[0008] The spiral ballway supports the steel balls with a spiral bottom plate, and constrains the position of the steel balls with the outer wall of the hollow shaft and the outer baffle, so that they can roll smoothly along the spiral bottom plate, avoiding them from falling off the spiral bottom plate, thereby ensuring the stability of steel ball transportation. The two-sided structure of the spiral ballway reduces material consumption and improves economic efficiency. The observation window is set on the outer baffle, which is convenient for observing the rolling status of the steel balls while reducing its own weight. It is also convenient to coordinate with the open end of the spiral ballway to deal with the problem of steel ball blockage, making it more flexible to use.

[0009] To further optimize the technical solution, the outer surface of the spiral bottom plate, the outer surface of the outer baffle plate and the outer surface of the hollow shaft are all coated with a ceramic coating.

[0010] After forging, the steel ball enters the spiral ball track. Since the steel ball itself has a certain temperature, a ceramic coating is applied to the outer surface of the spiral bottom plate, the outer surface of the outer baffle plate and the outer surface of the hollow shaft to reduce the thermal damage to the spiral ball track and the hollow shaft, and improve the wear resistance of the spiral ball track and the hollow shaft, ensuring safety in use and extending their service life.

[0011] To further optimize this technical solution, the hollow shaft includes a metal straight cylinder welded and fixed to the spiral base plate, and a ceramic sleeve is inserted into the metal straight cylinder; the bottom end of the metal straight cylinder is fixedly installed with a mounting base plate, the top end of the metal straight cylinder is fixedly installed with an upper cover, and a heat dissipation component is installed on the top of the upper cover.

[0012] The hollow shaft is based on a metal straight cylinder, which facilitates the welding and fixation of the spiral bottom plate and the metal straight cylinder. By installing the mounting base plate at the bottom end of the metal straight cylinder on the supporting surface, the hollow shaft and the spiral ball track are supported, and the upper cover at the top end of the metal straight cylinder closes the metal straight cylinder to protect the ceramic sleeve. The heat dissipation component installed on the top of the upper cover dissipates heat to the upper cover and the metal straight cylinder, reducing heat conduction to the ceramic sleeve and ensuring the stability of the electromagnet operation in the ceramic sleeve.

[0013] To further optimize the technical solution, the heat dissipation component includes a semiconductor refrigeration plate, the cold end of the semiconductor refrigeration plate is in contact with the upper cover, and the hot end of the semiconductor refrigeration plate is equipped with a heat dissipation fan.

[0014] When the semiconductor refrigeration chip is in operation, its cold end cools and dissipates heat to the upper cover, and the upper cover dissipates heat to the metal cylinder to reduce the temperature of the metal cylinder, while the cooling fan on the hot end of the semiconductor refrigeration chip dissipates heat to the semiconductor refrigeration chip to ensure its stable operation.

[0015] To further optimize this technical solution, the ceramic sleeve includes a ceramic straight cylinder that is slidably plugged into the metal straight cylinder, the electromagnet is assembled in the ceramic straight cylinder, and ceramic end covers are plugged into the top inner wall and the bottom inner wall of the ceramic straight cylinder, and the ceramic end covers are respectively abutted against the two end faces of the electromagnet.

[0016] The ceramic sleeve is mainly composed of a ceramic straight cylinder, and the electromagnet is built into the ceramic straight cylinder. Ceramic end covers are inserted into the top inner wall and the bottom inner wall of the ceramic straight cylinder. The ceramic end covers seal the ceramic sleeve and wrap and protect the electromagnet. The ceramic end covers are respectively abutted against the two ends of the electromagnet to constrain the position of the electromagnet, so that it is firmly built into the ceramic sleeve to ensure stability in use.

[0017] To further optimize this technical solution, the electromagnet includes an iron core and a coil wound on the iron core; flanges are detachably installed at both ends of the iron core, and the flanges are slidably connected to the inner wall of the ceramic straight cylinder with the help of guide components, and the end faces of the flanges are respectively in contact with the ceramic end covers.

[0018] The coil is wound on the iron core, and the diameter of the flanges at both ends of the iron core is larger than the diameter of the iron core, so that the coil is wound on the flange diameter. When the iron core is placed in the ceramic straight cylinder, the flange abuts against the inner wall of the ceramic straight cylinder to isolate the coil and prevent coil wear. The flange is assembled with the ceramic straight cylinder with the help of the guide component and the end face of the flange abuts against the ceramic end cover respectively, which enhances the constraint on the position of the electromagnet and ensures the firmness of the electromagnet assembly and the stability of use.

[0019] To further optimize the technical solution, the guide assembly includes protrusions arranged on the inner wall of the ceramic straight cylinder and notches arranged on the outer wall of the flange, the notches respectively match the number and positions of the protrusions, and the notches are respectively slidably plugged into the protrusions.

[0020] When the electromagnet is placed in the ceramic straight tube, the notch on the flange is plugged into the protrusion in the ceramic straight tube to prevent the electromagnet from shaking in the ceramic straight tube. The structure is simple and the use is stable and reliable.

[0021] The beneficial effects of the present invention are:

[0022] 1. The spiral bottom plate of the spiral ball track is welded and fixed on the outer wall of the metal straight tube. The outer wall of the spiral bottom plate is welded and fixed with an outer baffle to form the spiral ball track. After the steel ball rolls into the spiral ball track, it is supported by the spiral bottom plate and restricted in position by the metal straight tube and the outer baffle to prevent the steel ball from falling off and ensure the smooth rolling of the steel ball. The spiral ball track completes the steel ball transportation with a two-sided structure. After the structural optimization, the use of materials is reduced and the economic efficiency is improved.

[0023] 2. After the steel balls are forged and rolled into the spiral ball track, the electromagnet built into the hollow shaft is energized to generate magnetic attraction, and adsorbs the steel balls that have rolled into the spiral ball track, making them stick to the outer wall of the hollow shaft, sorting and guiding the steel balls. However, since the magnetic attraction of the electromagnet is lower than the gravity of the steel balls, the steel balls continue to roll down along the spiral ball track, ensuring the smoothness of steel ball transportation and improving the transportation efficiency of the steel balls;

[0024] 3. When the electromagnet is built into the ceramic sleeve, the flange on the electromagnet isolates the coil to avoid contact wear between the ceramic straight tube and the electromagnet, and limits the shaking of the electromagnet to ensure stability and reliability. The ceramic sleeve is built into the hollow shaft to reduce the heat conduction from the hollow shaft to the electromagnet, ensuring the stability of the electromagnet operation. In addition, a heat dissipation component is added to the hollow shaft to reduce the temperature on the hollow shaft, further ensuring the operation of the electromagnet.

[0025] 4. When the steel ball rolls along the spiral ball track, its open structure and the observation window on the outer baffle make it easy to observe the rolling situation of the steel ball. When blockage occurs in the spiral ball track, the operator can use tools to guide the steel ball through the open part and the observation window to improve the guidance efficiency.

[0033] The present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0034] Please see the attached Figure 1 , Attachment Figure 2, an open steel ball spiral descent device, comprising a hollow shaft 4 and an open spiral ball channel 3, the spiral ball channel 3 and the hollow shaft 4 are coaxially assembled, and the two ends of the hollow shaft 4 protrude from the top and bottom of the spiral ball channel 3 respectively, so that the hollow shaft 4 provides sufficient space for the assembly of the spiral ball channel 3, and the top and bottom of the spiral ball channel 3 are respectively connected to the in-ball channel 1 and the out-ball channel 2, the steel ball rolls into the spiral ball channel 3 through the in-ball channel 1 and rolls out through the out-ball channel 2, the spiral ball channel 3 comprises a spiral bottom plate 301 arranged on the outer wall of the hollow shaft 4, the inner wall of the spiral bottom plate 301 is welded and fixed to the outer wall of the hollow shaft 4, the outer wall of the spiral bottom plate 301 is welded and fixed with an outer baffle 302, the outer baffle 302 and the spiral bottom plate 30 1 matches the shape of the steel ball. When the steel ball rolls along the spiral ball track 3, the spiral ball track 3 supports the steel ball with the spiral bottom plate 301, and constrains the position of the steel ball with the outer wall of the hollow shaft 4 and the outer baffle 302, so that it rolls smoothly along the spiral bottom plate 301 and prevents it from falling off the spiral bottom plate 301, thereby ensuring the stability of steel ball transportation. When the steel ball rolls along the spiral ball track 3, it has a certain stability because it has just been forged. Therefore, a layer of ceramic coating is applied to the outer surface of the spiral bottom plate 301, the outer surface of the outer baffle 302 and the outer surface of the hollow shaft 4 to prevent heat from damaging the spiral ball track 3 and the hollow shaft 4, enhance the wear resistance of the spiral ball track 3 and the hollow shaft 4, and ensure safety in use.

[0035] Please see the attached Figure 2 , Attachment Figure 3 The hollow shaft 4 is based on a metal straight cylinder 401. The metal straight cylinder 401 is conveniently welded and fixed to the spiral bottom plate 301 to ensure its structural strength. A ceramic sleeve 5 is inserted into the metal straight cylinder 401. The ceramic sleeve 5 has an electromagnet 6 built in it. The ceramic sleeve 5 does not interfere with the magnetic attraction of the electromagnet 6 being transmitted to the metal straight cylinder 401. A mounting base 402 is fixedly installed at the bottom of the metal straight cylinder 401. The mounting base 402 is mounted on the supporting surface to support the metal straight cylinder 401 and the spiral ball track 3. An upper cover 403 is fixedly installed on the top of the metal straight cylinder 401. A heat dissipation component is installed on the top of the upper cover 403. The heat dissipation component performs heat dissipation treatment on the metal straight cylinder 401. The heat dissipation component includes a semiconductor cooling plate 4031. The cold end of the semiconductor cooling plate 4031 is in contact with the upper cover 403. When the semiconductor cooling plate 4031 is powered on, the cold end lowers the temperature of the upper cover 403, and the upper cover 403 dissipates heat from the metal straight cylinder 401, thereby reducing heat conduction to the ceramic sleeve 5 and ensuring stable operation of the electromagnet 6. The hot end of the semiconductor cooling plate 4031 is equipped with a heat dissipation fan 4032. The heat dissipation fan 4032 dissipates heat and cools the hot end, thus ensuring stable operation of the semiconductor cooling plate 4031 and ensuring reliability.

[0036] Please see the attached Figure 4 , Attachment Figure 5 The ceramic sleeve 5 is mainly composed of a ceramic straight cylinder 501, which is slidably connected to the metal sleeve. The electromagnet 6 is built into the ceramic straight cylinder 501. The top inner wall and the bottom inner wall of the ceramic straight cylinder 501 are connected with ceramic end caps 502. The ceramic end caps 502 are respectively in contact with the two end surfaces of the electromagnet 6, thereby limiting the position of the electromagnet 6 and enhancing the stability of the electromagnet 6 in the ceramic sleeve 5.

[0037] Please see the attached Figure 4 , Attachment Figure 6 The electromagnet 6 includes an iron core 601 and a coil 602 wound on the iron core 601. Flanges 603 are detachably mounted on both ends of the iron core 601. The diameter of the flanges 603 is larger than that of the iron core 601. The coil 602 is wound between the flanges 603. When the electromagnet 6 is built into the ceramic straight cylinder 501, the flanges 603 isolate the coil 602 to prevent it from contacting the ceramic straight cylinder 501 and causing wear. The flanges 603 are slidably connected to the inner wall of the ceramic straight cylinder 501 with the help of a guide assembly. The guide assembly includes a protrusion 5011 provided on the inner wall of the ceramic straight cylinder 501 and a notch 6031 provided on the outer wall of the flange 603. The notch 6031 matches the position and number of the protrusion 5011. When the protrusion 5011 is plugged into the notch 6031, the electromagnet 6 is constrained to prevent the electromagnet 6 from sliding inside the ceramic straight cylinder 501. In addition, the two ends of the ceramic end cap 502 are respectively abutted against the flanges 603 at both ends of the iron core 601, which improves the firmness of the assembly of the electromagnet 6 and ensures its reliability.

[0038] The working principle of the open steel ball spiral descent device is as follows: after the steel ball is forged and formed, it is transferred by the spiral ball channel 3. When the steel ball enters the spiral ball channel 3 from the ball channel 1, the electromagnet 6 built into the hollow shaft 4 is energized and generates a magnetic attraction force to adsorb the steel ball entering the spiral ball channel 3, so that the steel ball is close to the hollow shaft 4 and contacts the outer wall of the hollow shaft 4, thereby guiding and sorting the steel ball entering the spiral ball channel 3. However, since the magnetic attraction force of the electromagnet 6 is lower than the gravity exerted on the steel ball, the steel ball continues to roll down along the spiral ball channel 3, thereby avoiding the steel ball from being blocked in the spiral ball channel 3 and improving the transfer rate of the steel ball. The open structure of the spiral ball channel 3 and the observation port on the outer baffle 302 make it convenient to observe the running status of the steel ball. After blockage occurs in the spiral ball channel 3, the operator can use a crowbar or other tool to clear the blocked position of the steel ball through the open part of the spiral ball channel 3 and the observation window 7 on the outer baffle 302, thereby ensuring the steel ball conveying effect, and the operation is simple and efficient.
