Abstract
Description
Technical Field
[0001] The utility model belongs to sorting equipment, relates to steel ball sorting, and specifically relates to a steel ball weighing and sorting device. Background Art
[0002] When forging wear-resistant steel balls, the steel rods need to be heated first, and then cut into blanks of the required length by a rod shear, and then forged to produce wear-resistant steel balls of the specified size. In the process of cutting the blanks, there may be an accidental phenomenon that the steel cone cannot be pushed into place, causing the cut blanks to be slightly shorter than the normal blanks, so that the produced steel balls do not reach the specified size. Therefore, it is necessary to sort the steel balls after forming to select unqualified steel balls.
[0003] At present, steel balls are usually weighed by weighing method. Because the cut billet is slightly shorter, the weight of the forged steel ball will be slightly lower than the weight of the normal steel ball, so weighing can select unqualified steel balls. At present, unqualified steel balls are usually selected by manual weighing, which has a low degree of automation, resulting in low sorting efficiency, but high production costs. Utility Model Content
[0004] In order to solve the technical problem of high efficiency and low cost caused by low automation of steel ball weighing and sorting, the utility model provides a steel ball weighing and sorting device. A single-channel intermittent conveyor is used to sequentially convey single steel balls to a weighing platform for weighing, and the ball track baffle opens and closes the two channels to control the rolling position of the steel balls and sort the steel balls. The use is flexible, simple, and efficient.
[0005] The technical solution adopted by the utility model is: to provide a steel ball weighing and sorting device, including a weighing platform, a fence is arranged around the weighing platform, a single-channel intermittent conveyor is connected to one side of the fence, a "human" sorting ball lane inclined downward is connected to the front side of the fence, and the intersections of the sorting ball lanes are connected to each other, and a ball lane baffle is vertically arranged; a rotating shaft is arranged at one end of the ball lane baffle, the rotating shaft is rotatably installed with the intersection of the sorting ball lane by means of a driving mechanism, and the free ends of the ball lane baffle are respectively abutted against the inner wall of the sorting ball lane; a pushing mechanism is arranged at the rear side of the fence, and the output end of the pushing mechanism penetrates into the fence.
[0006] The formed steel balls are conveyed to a single-channel intermittent conveyor. The single-channel intermittent conveyor lines up the steel balls and conveys them to the weighing table in sequence, so that the weighing table weighs the individual steel balls in sequence to ensure the weighing effect. The intermittent conveying of the steel balls reserves weighing time for the steel balls to ensure weighing accuracy. After the steel balls roll onto the weighing table, the enclosures on the sides thereof can prevent the steel balls from falling. After the steel balls are weighed, they are pushed into the sorting lanes by the pushing mechanism. The herringbone structure of the sorting lanes divides the lanes into two lanes, thereby sorting the steel balls. The lane baffles are rotatably installed at the intersection of the sorting lanes. The lane baffles are driven to rotate according to the quality of the steel balls with the help of a driving mechanism to block one of the sorting lanes, thereby achieving the sorting effect. The structure is simple, and the use is flexible and efficient.
[0007] To further optimize the technical solution, a buffer pad is laid on the top of the weighing platform, the top of the buffer pad is a concave surface, and a damping pad is laid on the top of the buffer pad.
[0008] When the steel ball rolls down onto the weighing platform, the buffer pad reduces the impact of the steel ball on the weighing platform. The concave surface on the top of the buffer pad and the damping pad laid inside the concave surface prevent the steel ball from moving around after it falls into the lowest point of the concave surface, thereby ensuring the weighing effect and weighing accuracy, and improving the weighing efficiency.
[0009] To further optimize the technical solution, the single-channel intermittent conveyor includes a belt conveyor driven by an intermittent motor, limit strips are arranged on both sides of the conveying belt of the belt conveyor, and spacer strips are evenly arranged on the outer surface of the conveying belt.
[0010] When the steel balls are transported by the belt conveyor, the limit bars on both sides of the conveyor belt can prevent the steel balls from falling from the belt conveyor, and the limit bars allow a single steel ball to pass through the conveyor belt, so that the steel balls are transported in a row on the conveyor belt. The spacers evenly arranged on the outer surface of the conveyor belt support and separate the steel balls so that the steel balls fall onto the weighing platform one by one without interference, and the use is smooth. The conveyor belt is intermittently driven by an intermittent motor, so that the steel ball stops running after falling onto the weighing platform, reserving time for the weighing of a single steel ball, and the use is flexible.
[0011] To further optimize the technical solution, the rotating shaft passes downward through the sorting ball lane and is fixedly installed with a cross bar, the cross bar is vertically arranged with the rotating shaft, and the cross bar is rotatably hinged with the driving mechanism.
[0012] The rotating shaft passes through the sorting ball channel downward and is connected to the driving mechanism, so that the inside of the sorting ball channel is smoother, and the interference of the steel balls sliding along the sorting ball channel is avoided, thereby ensuring the smoothness of use.
[0013] To further optimize the technical solution, the driving mechanism includes a cylinder fixedly mounted on the bottom of the sorting lane, and the output end of the cylinder is rotatably hinged to the crossbar.
[0014] The output end of the cylinder is rotatably hinged with the cross bar at the bottom end of the rotating shaft. When the cylinder is running, the cross bar is pushed to drive the rotating shaft to rotate, thereby adjusting the position of the ball lane baffle to block one of the sorting ball lanes, so that the steel balls roll down along the unobstructed ball lane, thereby realizing the sorting of the steel balls. The structure is simple and the use is stable and reliable.
[0015] To further optimize the technical solution, the sorting lane includes a good quality lane and a substandard quality lane that are connected to each other, and the good quality lane is connected to the enclosure.
[0016] By moving the lane baffles into the good lane and the defective lane respectively, the good lane and the defective lane are connected and blocked, so that the screened steel balls roll down along the corresponding lanes respectively, and the good and defective steel balls are sorted.
[0017] To further optimize the technical solution, the pushing mechanism includes an electric push rod fixedly installed on the rear side of the enclosure, and the output end of the electric push rod penetrates into the enclosure and corresponds to the position of the sorting lane.
[0018] After the weighing platform finishes weighing the steel balls, the electric push rod on the rear side of the enclosure runs, and its output end penetrates into the enclosure, pushing the steel balls into the sorting lane for sorting operations, and then the output end of the electric push rod contracts and the steel balls are not weighed again.
[0019] The beneficial effects of the utility model are:
[0020] 1. The limit strips on both sides of the conveyor belt and the spacers evenly arranged on the outer surface of the conveyor belt make the steel balls line up on the conveyor belt and avoid mutual interference between the steel balls, so that the single steel balls fall into the weighing platform one by one. The intermittent motor drives the conveyor belt intermittently, which reserves time for the steel balls to be weighed on the weighing platform to ensure the weighing effect.
[0021] 2. When the steel ball falls onto the weighing platform, the enclosure prevents the steel ball from falling off the weighing platform. The buffer pad on the top of the weighing platform reduces the impact damage of the steel ball on the weighing platform. The concave surface on the top of the buffer pad and the damping pad laid inside the concave surface make the steel ball fall to the lowest point of the concave surface and limit the movement of the steel ball, thereby improving the weighing accuracy. After the weighing is completed, the electric push rod on the rear side of the enclosure is used to push the steel ball into the sorting ball lane for sorting operations. It is easy to use.
[0022] 3. The herringbone structure of the sorting lane divides the good lane and the defective lane. The intersection of the sorting lanes is installed with a lane baffle driven by a cylinder. The steel balls are sorted by adjusting the position of the lane baffle. When sorting qualified steel balls, the lane baffle turns to the defective lane to connect the good lane so that the qualified steel balls can pass through the lane smoothly. When sorting unqualified steel balls, the lane baffle turns to the good lane to block it so that the unqualified steel balls roll into the defective lane. The sorting is simple and the use is stable and reliable. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0031] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0032] Please see attached Figure 1-3The steel ball weighing and sorting device comprises a weighing platform 1, a fence 2 is arranged around the weighing platform 1, a single-channel intermittent conveyor is connected to one side of the weighing platform 1, and the front end of the single-channel intermittent conveyor is connected to the steel ball forming equipment, and the formed steel balls are transported to the single-channel intermittent conveyor. The single-channel intermittent conveyor is a belt conveyor driven by an intermittent motor. Limiting strips 501 are arranged on both sides of the conveying belt 503 of the belt conveyor. The limiting strips 501 can prevent the steel balls from falling from the belt conveyor, and the outer surface of the conveying belt 503 is evenly provided with partitions 502. The partitions 502 limit the steel balls to prevent the steel balls from moving randomly. Therefore, when the belt conveyor transports the steel balls, the steel balls are lined up on the belt conveyor, and the steel balls are transported to the weighing platform 1 in sequence. The intermittent opening and closing of the intermittent motor makes it possible to replace the steel balls for weighing after the single steel ball is weighed on the weighing platform 1, so as to facilitate the weighing of the steel balls in sequence and avoid interference with the weighing results.
[0033] Please see attached Figure 1-2 And attached Figure 4-5 When the steel ball is transported to the weighing platform 1, a fence 2 is provided on the surrounding side of the weighing platform 1, which can prevent the steel ball from falling from the weighing platform 1. A buffer pad 101 is laid on the top of the weighing platform 1 to prevent the steel ball from causing impact damage to the weighing platform 1, and the top surface of the buffer pad 101 is a concave surface 1011, which can make the steel ball slide smoothly to the lowest point of the concave surface 1011 to prevent the steel ball from moving around and interfering with the weighing effect. At the same time, a damping pad 1012 is laid on the concave surface 1011 of the buffer pad 101, which can limit the movement of the steel ball, ensure the weighing accuracy and weighing efficiency, and protect the steel ball and the weighing platform 1;
[0034] Please see attached Figure 1-2 The front side of the enclosure 2 is connected to a "human" sorting lane 3 inclined downward, and a pushing mechanism is arranged on the rear side of the enclosure 2. The pushing mechanism is an electric push rod 7. The output end of the electric push rod 7 penetrates into the enclosure 2 and corresponds to the position of the sorting lane 3. After the steel ball is weighed, the electric push rod 7 runs to push the steel ball to move and push it from the weighing platform into the sorting lane 3. The inclined setting of the sorting lane 3 makes the steel ball roll downward under gravity;
[0035] Please see attached Figure 1-2 and attached Figure 7The intersections of the herringbone sorting lanes 3 are connected to each other, and a lane baffle 4 is vertically arranged. A rotating shaft 401 is arranged at one end of the lane baffle 4. The rotating shaft 401 is rotatably installed with the intersection of the sorting lane 3 by means of a driving mechanism. After the driving mechanism drives the rotating shaft 401 to rotate, the position of the lane baffle 4 is adjusted. The rotating shaft 401 passes through the sorting lane 3 downward and is fixedly installed with a cross bar 402. The cross bar 402 is vertically arranged with the rotating shaft 401, and the cross bar 402 is connected to the driving mechanism. The structure is rotatably hinged, and the driving mechanism is a cylinder 6 fixedly installed at the bottom of the sorting ball lane 3. The output end of the cylinder 6 is rotatably hinged with the crossbar 402. When the cylinder 6 is running, it pushes the crossbar 402 to rotate, and drives the rotating shaft 401 and the ball lane baffle 4 to rotate synchronously. The sorting ball lane 3 includes a good ball lane 301 and a defective ball lane 302 that are connected to each other. When the position of the ball lane baffle 4 is adjusted, the ball lane baffle 4 is respectively abutted against the inner wall of the good ball lane 301 or the defective ball lane 302;
[0036] Please refer to the attached Figure 1-2 and attached Figure 6 After the weighing of the steel balls is completed, the weighing platform 1 feeds back the weighing data of the steel balls to the central processor to determine the quality of the steel balls. When it is determined that the quality of the steel balls is correct, the ballway baffle 4 is driven by the cylinder 6 and abuts against the inner wall of the defective ballway 302, thereby blocking the defective ballway 302 and making the steel balls roll down along the good ballway 301 to collect the good steel balls. When the quality of the steel balls deviates, after the data is fed back to the central processor, the central processor sends a driving signal to operate the cylinder 6 to rotate the ballway baffle 4 into the good ballway 301 to block the good ballway 301. After the steel balls rolling down the sorting ballway 3 encounter obstacles, they change their rolling direction to roll into the defective ballway 302 and collect the defective steel balls.
[0037] The working principle of the steel ball weighing and sorting device is as follows: after the steel balls are processed and formed on the forming equipment, they are conveyed to a single-channel intermittent conveyor, so that the steel balls are transferred to the weighing platform 1 for quality inspection with the help of the belt conveyor 5. When the conveying belt 503 conveys the steel balls, the limit bars 501 on both sides and the spacers 502 evenly distributed on the surface restrain the steel balls to prevent the steel balls from falling from the belt conveyor 5, and at the same time, the steel balls are lined up on the conveying belt 503, and with the operation of the conveying belt 503, they roll down to the weighing platform 1 in turn, so that the individual steel balls are weighed and inspected in turn, and the intermittent motor drives the intermittent operation of the belt conveyor 5 to provide weighing time for the weighing of individual steel balls, thereby ensuring the weighing effect and accuracy.
[0038] When the steel ball falls onto the weighing platform 1, the enclosure 2 around the weighing platform 1 can prevent the steel ball from falling off the weighing platform 1. The buffer pad 101 laid on the weighing platform 1 reduces the impact of the steel ball on the weighing platform 1. The concave surface 1011 structure on the top surface of the buffer pad 101 and the damping pad 1012 laid on the concave surface 1011 make the steel ball roll to the lowest point of the concave surface 1011 and limit the movement of the steel ball, thereby improving the weighing quality. After the weighing is completed, the electric push rod 7 runs to push the steel ball from the weighing platform 1 to the sorting ball lane 3. The inclined frame of the sorting ball lane 3 Assume that the steel balls are made to roll down along the sorting ball lane 3, and after the steel balls are weighed, the weighing data is fed back to the central processor for data analysis and processing, and the position of the ball lane baffle 4 is adjusted. When the quality of the steel balls is qualified, the ball lane baffle 4 blocks the defective ball lane 302, so that the steel balls roll down along the good ball lane 301. When the quality of the steel balls is unqualified, the cylinder 6 drives the ball lane baffle 4 to rotate with the help of the cross bar 402, and blocks the good ball lane 301, so that the steel balls roll into the defective ball lane 302, thereby sorting the steel balls. It is easy to use and efficient.
