Description

Technical Field

[0001] The invention relates to the technical field of steel ball production, and in particular to a feeding device for steel ball production and processing. Background Art

[0002] Steel balls can be divided into grinding steel balls, forging steel balls and casting steel balls according to different production and processing techniques. According to the processing materials, they can be divided into bearing steel balls, stainless steel balls and carbon steel balls. Steel balls are widely used and are often used in bearings, hardware, electricity, mining and metallurgy. Therefore, there are more and more steel ball manufacturers at this stage. In the production and processing of steel balls, it is necessary to use the casting process to initially manufacture the steel balls. At this time, the steel balls may be bonded with the molding sand. Therefore, dry grinders are usually used to remove sand and polish the steel balls to ensure the appearance performance of the steel balls. After the steel balls are removed and polished, they will be sent to the next process through the feeder for the next step of processing.

[0003] At present, common feeders are generally screw feeders or belt feeders. In order to meet the transmission requirements of steel balls, belt feeders are generally selected for transportation. By setting a partition on the belt, the steel balls can be placed in the partition and then transmitted from the outlet of the dry grinder to the next process. However, during the transportation process, it was found that since the steel balls are made of metal and there is a large gap between the end of the feeder and the next process, when the steel balls fall from the end of the feeder into the feed port of the next process, the surface of the steel balls may collide violently with the objects below, leaving marks, thereby reducing the quality of the steel balls and causing the defective rate of steel balls to remain high.

[0004] Therefore, it is necessary to provide a feeding device for steel ball production and processing to solve the above technical problems. Summary of the invention

The two buffer plates 29 are distributed one above and one below in terms of orientation, and are relatively distributed in terms of rotation orientation, that is, the two rotation directions are opposite. When the steel ball falls on the upper buffer plate 29, the buffer plate 29 tilts to the lower right to slowly guide the steel ball to the lower buffer plate 29. When the lower buffer plate 29 is at the lower left, it tilts to the lower left, so that the steel ball rolls in a "Z" shape, and an arc buffer rod 30 is slidably installed on the side where the female guide sleeve 27 and the sub-guide sleeve 28 are away from each other. The top ends of the two arc buffer rods 30 are respectively fixedly connected to the two buffer plates 29, and the two arc buffer rods 30 are sleeved with buffers.

Fixed blocks 32 are fixedly installed on the outer walls of both sides of the female guide sleeve 27 and the sub-guide sleeve 28, and slots 33 are provided at the bottoms of the four fixed blocks 32. The corresponding two fixed blocks 32 are provided with movable holes 34 on the side away from each other.

By rotating the disc 39, the clamping effect between the wedge-shaped clamping head 37 and the movable hole 34 can be removed.

[0041] In the above method, in order to form a reliable installation of the female guide sleeve 27, a mounting beam 24 is fixedly installed on one side of the standing plate 4, and a connecting arm 25 is fixedly installed at the bottom of the mounting beam 24. One side of the connecting arm 25 is fixedly connected to the female guide sleeve 27. In order to smoothly guide the steel ball falling from the belt sleeve 6 to the buffer plate 29 in the female guide sleeve 27, two folding rods are fixedly installed at the bottom of the mounting beam 24, and the ends of the two folding rods are fixedly installed with the same guide channel steel 26, the top of the guide channel steel 26 is located below the end of the belt sleeve 6, and the bottom end of the guide channel steel 26 is located below the female guide sleeve 27.

[0042] The above-mentioned pushing mechanism also includes two eccentric shafts 40, which are fixedly mounted on the disc 39, and are hinged with hinge arms 43 on the two eccentric shafts 40, and two stabilizing plates 41 are fixedly mounted on one side outer wall of the female guide sleeve 27 and the sub-guide sleeve 28, wherein linkage slide bars 42 are slidably mounted on the two stabilizing plates 41 on the female guide sleeve 27, and the ends of the two linkage slide bars 42 close to each other are rotatably connected to the corresponding hinge arms 43, and the two linkage slide bars 42 are fixedly sleeved with limit rings 44, and the two linkage slide bars 42 are sleeved with second return springs 45, and the ends of the two second return springs 45 close to each other are They are respectively fixedly connected to the two stabilizing plates 41, and the ends of the two second return springs 45 that are away from each other are respectively fixedly connected to the two limit rings 44, and the ends of the two linkage slide rods 42 that are away from each other are fixedly installed with connecting pieces 46, and the sides of the two connecting pieces 46 that are close to each other are fixedly installed with pushing heads 47. The two pushing heads 47 are respectively adapted to the two movable holes 34, and by rotating the disk 39, under the articulated linkage of the articulated arm 43, the two linkage slide rods 42 can form a movement approaching each other, and then the pushing heads 47 can be brought into the movable hole 34, and finally the wedge-shaped locking head 37 is brought out of the movable hole 34, thereby completing the removal of the sub-guide sleeve 28.

[0043] In this method, in order to quickly replace the belt sleeve 6, a peripheral connecting frame 9 is fixedly installed on the side of the back bearing plate 2 away from the driving roller 5. A first one-way lead screw 10 is rotatably installed in the peripheral connecting frame 9. A longitudinal push plate 11 is threadedly installed on the first one-way lead screw 10. And two guide rods 12 are fixedly installed on the side of the longitudinal push plate 11 close to the standing plate 4. Both of the two guide rods 12 penetrate through the standing plate 4 and are slidably connected with the standing plate 4. And the same thrust ring 13 is fixedly installed at one end of the two guide rods 12 close to the belt sleeve 6. The inner diameter of the thrust ring 13 is the same as the outer diameter of the driving roller 5, so that it can be sleeved on the driving roller 5 and directly push out the belt sleeve 6. And a first servo motor is fixedly installed on the outer wall of one side of the peripheral connecting frame 9, and its output shaft is fixedly connected with one end of the first one-way lead screw 10.

[0044] In this method, in order to form rolling support for the ends of the two driving rollers 5, a bearing plate 14 is arranged above the support table 1. A second mounting plate 15 is fixedly installed on its top. A standing plate 16 is fixedly installed on the top of the second mounting plate 15. Two rolling holes 17 are opened on the standing plate 16. One end of each of the two driving rollers 5 penetrates through the two rolling holes 17 respectively. And ball bearings are embedded on the inner walls of the two rolling holes 17. The ends of the two driving rollers 5 are in contact with the ball bearings, so as to ensure that the driving rollers 5 can rotate smoothly. And a U-shaped connecting frame 18 is fixedly installed on one side of the back bearing plate 2. A second one-way lead screw 19 is rotatably installed in it. A linkage folding plate 20 is threadedly installed on the second one-way lead screw 19.

A second servo motor is fixedly installed on the top of the U-shaped connecting frame 18, and its output shaft is fixedly connected with the top end of the second one-way lead screw 19. And two limiting rods are fixedly installed on the top of the support table 1. Both of the two limiting rods penetrate through the linkage folding plate 20 and are slidably connected with the linkage folding plate 20, so as to play a limiting role on the linkage folding plate 20, so that the linkage folding plate 20 can only move up and down linearly.

[0045] In this method, in order to drive the driving roller 5 to rotate, a third servo motor is fixedly installed on the top of the standing plate 4. Sprockets are fixedly sleeved on the output shaft and one end of one of the driving rollers 5 respectively. The same chain is sleeved on the two sprockets. In addition, a plurality of supporting rollers 23 are fixedly installed on the side of the standing plate 4 close to the driving roller 5. The upper inner surface of the belt sleeve 6 is in contact with the plurality of supporting rollers 23, so as to form a support for the belt sleeve 6, prevent the upper part of the belt sleeve 6 from loosening, and ensure the stability of the steel ball transmission.

[0046] In this embodiment

[0047] The number of the sub-guide sleeves 28 is selected and used according to actual needs. When the female guide sleeve 27 is far away from the feed port of the next process, in order to make the steel ball fall smoothly into the next process, a sub-guide sleeve 28 can be taken out, and the plug-in plates 35 on both sides thereof are aligned with the slots 33 on both sides of the female guide sleeve 27, and then inserted from bottom to top. When the wedge-shaped positioning head 37 on the plug-in plate 35 contacts the bottom edge of the slot 33, under the action of the first return spring 38, the wedge-shaped positioning head 37 will automatically retract into the receiving groove 36 until the plug-in plate 35 and the top of the slot 33 are aligned. After the inner wall of the part is in contact, the plug-in plate 35 is now horizontally corresponding to the movable hole 34. At this time, the compressed first return spring 38 releases its elastic force, and the wedge-shaped locking head 37 is directly brought into the movable hole 34, thereby forming a locking effect, and at this time, the connection between a sub-guide sleeve 28 and the female guide sleeve 27 is completed. Subsequently, in the same manner as above, the remaining sub-guide sleeves 28 are taken out in turn, and the sub-guide sleeves 28 are installed between the previous sub-guide sleeves 28 in turn, until the distance between the lowest sub-guide sleeve 28 and the feed port of the next process is extremely close;

[0048] When the steel ball is being transported, the third servo motor is started first, and its output shaft drives the corresponding sprocket to rotate. At this time, the corresponding transmission roller 5 starts to rotate by the transmission mode of the chain, and then the belt cover 6 can be driven. Subsequently, the dry grinder spits the processed steel ball onto the belt cover 6 and is located between two adjacent rubber interlayers 7, and the transmission starts at this time.

[0049] When the steel ball is transmitted to the end of the belt sleeve 6, the steel ball will fall into the guide groove steel 26, and then fall into the buffer plate 29 in the female guide sleeve 27. At this time, under the action of the buffer spring 31, the buffer plate 29 slowly tilts downward, and the steel ball will slowly roll and roll to the next buffer plate 29, and use the corresponding buffer spring 31 again to form a buffer, so that it rolls smoothly again and falls on the next buffer plate 29. After that, it is reciprocated until the steel ball rolls to the bottom buffer plate 29, and finally rolls to the feed port position in the next process. At this time, the steel ball is discharged smoothly in a buffered manner, and in the process of discharging the steel ball, the previous steel ball will be discharged in the same way.

[0050] In subsequent use, when it is necessary to remove the sub-guide sleeve 28, start from the bottom sub-guide sleeve 28, rotate the disc 39 thereon, and under the action of the eccentric shaft 40 and the hinge arm 43, the corresponding two linkage slide bars 42 move towards each other, at this time, the corresponding two push heads 47 approach each other and enter the corresponding active holes 34, when the push heads 47 contact the wedge-shaped positioning heads 37, they push the wedge-shaped positioning heads 37 and gradually push them out of the active holes 34, until they are completely moved out of the active holes 34, then the sub-guide sleeve 28 can be directly pulled down, thereby completing the disassembly work, and then the remaining sub-guide sleeves 28 can be removed in sequence by the same operation;

[0051] In the later stage, when the belt cover 6 needs to be replaced due to aging of its own material, in order to facilitate people's replacement, the output shaft of the cylinder 22 can be started to extend, and its output shaft drives the bearing plate 14 to move away from the transmission roller 5, and finally separates the two transmission rollers 5 from the standing plate 16, and then the second servo motor is started in the positive direction, and its output shaft drives the second one-way screw 19 to rotate, so that the linkage folding plate 20 and the cross arm 21 are lowered, and finally the standing plate 16 is lowered from one side of the transmission roller 5 to the bottom thereof, and the two do not hinder each other, and then the first servo motor is started in the positive direction, and its output shaft drives the first one-way screw 10 to rotate, and the longitudinal push plate 11 moves with the two guide rods 12 toward the direction of the belt cover 6, and at the same time, the push ring 13 also moves with the cabinet, and when the push ring 13 contacts the belt cover 6, it will push the belt cover 6, so that the belt cover 6 is pushed out from the transmission roller 5 at one time, and then the first servo motor is started in the reverse direction, and the push ring 13 is brought back to the original position, and then the new belt cover 6 is sleeved on the two transmission rollers 5;

[0052] Subsequently, the second servo motor is started in the reverse direction to bring the standing plate 16 back to the original height, and then the output shaft of the cylinder 22 is started to retract, so that the ends of the two driving rollers 5 are inserted into the corresponding rolling holes 17 again.

[0053] Compared with the related art, the feeding equipment for steel ball production and processing provided by the present invention has the following beneficial effects:

[0054] 1. The present invention can form a series of buffering effects on the falling steel ball by providing the female guide sleeve 27 and the sub-guide sleeve 28, as well as the buffer plate 29 and the buffer spring 31 and other components provided inside the two, so as to prevent the steel ball from violently hitting when falling from a high distance, effectively protect the outer surface of the steel ball, and thus reduce the defective rate of the steel ball. In addition, the number of sub-guide sleeves 28 can be selected according to the actual drop height for installation and use. The whole installation method is relatively simple. It only needs to insert the sub-guide sleeve 28 from bottom to top and insert the plug-in board 35 thereon into the slot 33, which has a high degree of convenience.

[0055] 2. The push ring 13 provided in the present invention can remove the belt cover 6 from the driving roller 5 at one time under the horizontal movement of the longitudinal push plate 11, so that people can easily replace the belt cover 6, and the removed belt cover 6 can be quickly removed only through the cooperation of the second one-way screw 19 and the cylinder 22. Compared with the traditional complicated dismantling process, this method is more convenient.

[0056] Second embodiment:

[0057] Based on the feeding equipment for steel ball production and processing provided in the first embodiment of the present application, the second embodiment of the present application proposes another feeding equipment for steel ball production and processing. The second embodiment is only a preferred mode of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0058] The second embodiment of the present invention is further described below in conjunction with the accompanying drawings and implementation modes.

[0059] Please refer to Figure 15-18 The feeding equipment for steel ball production and processing also includes two support plates 52, both of which are fixedly installed on one side of the back load-bearing plate 2, and linkage rods 53 are slidably installed on the two support plates 52, and arc-surface resistance seats 54 are fixedly installed on the tops of the two linkage rods 53. By raising and lowering the arc-surface resistance seats 54, the tension of the belt cover 6 can be adjusted, thereby ensuring that the belt cover 6 does not slip on the transmission roller 5.

[0060] In the above manner, in order to drive the two arc-surface abutment seats 54 to rise and fall synchronously, wedge-shaped sockets 55 are fixedly installed at the bottom of the two linkage rods 53, and third return springs 56 are sleeved on the two linkage rods 53. The top ends of the two third return springs 56 are fixedly connected to the two support plates 52, and the bottom ends of the two third return springs 56 are fixedly connected to the two wedge-shaped sockets 55, respectively. A concave frame 48 is fixedly installed at the bottom of the support platform 1, and the same bidirectional lead screw 49 is rotatably installed on both sides of the concave frame 48, and two transverse push plates 50 are threadedly installed on the bidirectional lead screw 49, and the tops of the two transverse push plates 50 extend to the top of the support platform 1 and are connected to the support platform 1 is slidably connected, and the two sides of the two horizontal push plates 50 that are close to each other are fixedly installed with wedge plugs 51, and the sides of the two wedge plugs 51 that are close to each other are respectively in conflict with the two wedge sockets 55, and a fourth servo motor is fixedly installed at the bottom of the support platform 1, and its output shaft and the two-way lead screw 49 are fixedly sleeved with gears, and the two gears are meshed. Through the shape adaptation between the wedge plugs 51 and the wedge sockets 55, when the two-way lead screw 49 rotates, the two wedge plugs 51 can be brought close to each other, so that they can form a conflict with the wedge sockets 55, and finally the arc-surface conflict seat 54 is raised, so that the tension of the belt cover 6 can be adjusted.

[0061] In this embodiment

[0062] During long-term use, the belt cover 6 will become loose due to long-term large tension. At this time, in order to prevent the belt cover 6 from slipping, the fourth servo motor can be started in the positive direction, and the two-way lead screw 49 can be driven to rotate through the meshing between the two gears, and the two horizontal push plates 50 are close to each other. At this time, the two wedge-shaped plugs 51 will push the corresponding wedge-shaped sockets 55, and the two wedge-shaped sockets 55 begin to rise, and then they can rise with the arc surface contact seat 54. At this time, the two third return springs 56 are also stressed and in a compressed state. When the arc surface contact seat 54 contacts the lower part of the belt cover 6, it will push this part upward. At this time, the belt cover 6 is gradually tightened. When its tension reaches the appropriate use requirement, the fourth servo motor can be turned off.

[0063] Subsequently, the tension of the belt sleeve 6 can be adjusted in the same manner as described above whenever the belt sleeve 6 becomes loose.

[0064] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
