[0020] 1. In the automatic loading and unloading mechanism of the centerless grinder, a No. 1 threaded rod, a No. 1 gear, a No. 1 gear, a No. 2 gear and a No. 2 threaded rod are driven by a motor to rotate. During the rotation of the No. 2 threaded rod, the No. 2 sliding member, the No. 1 sliding member and the No. 3 connecting rod which are in close contact with the No. 2 threaded rod are driven to slide from right to left. The No. 3 connecting rod is blocked by the blocking member on the left side and during the sliding process, and the No. 5 raised column is pushed to the right. Under the influence of the spring, the extension rod moves the No. 3 raised column, so that the thread groove is in contact with the No. 1 threaded rod, and drives the No. 2 sliding member and the No. 1 sliding member to move to the right until they reach the position of the right blocking member. During the rotation of the No. 2 sliding member, the reciprocating paddle is driven to rotate. The reciprocating paddle rotates counterclockwise by a certain angle. When the thread groove is in contact with the No. 1 threaded rod, the position of the reciprocating paddle is just at the top of the semicircular groove, which can transport the rod and realize the continuous transportation of the rod by left and right reciprocating sliding. No manual operation is required, and the safety of the staff can be ensured.

[0021] 2. In the automatic loading and unloading mechanism of this centerless grinder, by setting an inclined plate at the end of the previous process, the bar is slipped from the top of the inclined plate to the bottom of the first conveyor track. Utilizing the angle between the first baffle and the inclination of the first conveyor track, the bar is conveyed to the inner side of one end of the first conveyor track. Due to the inertia of the first conveyor track, the bar will roll into the square hole and be supported by the two conical rollers on both sides and stabilized at the top of the conical rollers. At the same time, the conical rollers rotate driven by electricity, conveying the bar towards the direction of the semi-circular groove until it is conveyed into the semi-circular groove and then conveyed to the V-shaped groove on the top of the correction plate by the conveying device. Through the continuous conveying of the conveying device, every time a bar is conveyed to the top of the V-shaped groove, the previous bar will be pushed into the centerless grinder by a certain amount. In this way, the cycle repeats, and the bar can be continuously conveyed into the centerless grinder for grinding, and finally slide down the inclined second conveyor track to the second conveyor track and be sent out, and finally neatly stacked in the placement box set outside the bottom, which can save labor costs and ensure production efficiency.

[0036] Embodiment 1

[0037] Please refer to Figures 1-9As shown in the figure, this embodiment provides an automatic loading and unloading mechanism for a centerless grinding machine, including a centerless grinding machine 1 and a conveying chamber 2.

A conveying device 4 for conveying and correcting the position of the bars is arranged in the conveying chamber 2. A reciprocating paddle 454 for conveying the bars to the centerless grinding machine 1 is arranged in the conveying device 4. A correcting plate 23 for adjusting the position of the bars is arranged in the conveying chamber 2. A spring 48 for reciprocating the reciprocating paddle 454 is arranged in the conveying device 4. Wherein: through the rotation of the conveying device 4, the reciprocating paddle 454 and the spring 48 are used to continuously convey the bars, and at the same time, the conveying chamber 2 and the correcting plate 23 are used to correct the position of the bars.

[0038] An inlet 11 is arranged on one side of the centerless grinding machine 1, and an outlet 12 is arranged on the other side of the centerless grinding machine 1. A conveying chamber 2 is arranged on the side of the inlet 11 of the centerless grinding machine 1, and a bottom plate 3 is arranged on the side of the outlet 12 of the centerless grinding machine 1.

[0039] A first conveying track 21 is fixedly connected to one side of the conveying chamber 2. A first baffle 211 is fixedly connected to the outer wall of the first conveying track 21. The bottom inner wall of the conveying chamber 2 is fixedly connected to a first conveying track 22 through multiple columns. A semi-circular groove 221 is opened at the inner bottom of the first conveying track 22. A square hole 222 is opened at the inner side of the first conveying track 22 near one end of the first conveying track 22. The square hole 222 is communicated with the semi-circular groove 221, and the two are in the same vertical plane. Wherein: conical rollers 2221 are arranged at the four corners inside the square hole 222. A connecting column 2222 is fixedly connected between the two opposite conical rollers 2221 on both sides. A belt 2223 is sleeved on one side of the other two conical rollers 2221. Multiple conical rollers 2221 are rotatably connected to the inner wall of the square hole 222.

[0040] A correcting plate 23 is fixedly connected to the first conveying track 22 at the end far from the first conveying track 21. The bottom of the correcting plate 23 is fixedly connected to the inner bottom of the conveying chamber 2 through multiple columns. A V-shaped groove 231 is opened at the center of the top of the correcting plate 23. The V-shaped groove 231 is communicated with the semi-circular groove 221. Limiting plates 232 are fixedly connected to the top of both sides of the correcting plate 23. The limiting plates 232 are distributed on both sides of the V-shaped groove 231.

[0041] A second conveying track 31 is fixedly connected to the top of the bottom plate 3 through multiple columns. A plurality of second baffles 311 are fixedly connected to the outer wall of the second conveying track 31. One end of the second conveying track 31 is provided with a second conveying track 32. The second conveying track 32 is in an inclined state. The second conveying track 32 is communicated with the outlet 12 at the end far from the second conveying track 31.

[0042] At the top of the first conveying track 22, there is a conveying device 4. Inside the conveying device 4, there is a motor 41. One end of a first threaded rod 411 is fixedly connected to the output end of the motor 41. The other end of the first threaded rod 411 is fixedly connected to a first gear 412. The first gear 412 is meshed with a second gear 42. On one side of the second gear 42, there is a second threaded rod 421 fixedly connected. Fixed columns 422 are arranged on the outer walls at both ends of the second threaded rod 421. The second threaded rod 421 is rotatably connected to the inside of the fixed columns 422.

[0043] It can be seen from this that when it is necessary to automatically convey the bar stock into the centerless grinder 1 for grinding, and it is necessary to ensure that its entry will not cause damage to the bar stock and the equipment due to the deviation of the entry angle. For example, Figures 3-6 As shown, an inclined plate is arranged at the end of the previous process. The bar stock slides from the top of the inclined plate to the bottom of the first conveying track 21. The bar stock is conveyed to the inner side of one end of the first conveying track 22 by using the included angle between the first baffle 211 and the inclination of the first conveying track 21. Due to the inertia of the first conveying track 21, the bar stock will roll into the square hole 222 and is supported by the two conical rollers 2221 on both sides and stabilized on the top of the conical rollers 2221. At the same time, the conical rollers 2221 rotate under the drive of electricity, and the bar stock is conveyed towards the semi-circular groove 221 until it is conveyed into the semi-circular groove 221 and is conveyed to the V-shaped groove 231 on the top of the correction plate 23 through the conveying device 4. Through the continuous conveying of the conveying device 4, every time a bar stock is conveyed to the top of the V-shaped groove 231, the previous bar stock will be pushed into the centerless grinder 1 by a certain part. In this way, it can be continuously conveyed into the centerless grinder 1 for grinding, and finally slides from the inclined second conveying track 32 to the second conveying track 31 and is sent out, and finally neatly stacked in the placement box arranged outside the bottom, which can save labor costs and ensure production efficiency.

[0044] Embodiment 2

[0045] For example, Figures 6-9 As shown, at the top of the two fixed columns 422, there is a reciprocating fixing plate 43 fixedly connected. On one side of the upper end of the reciprocating fixing plate 43, there is an extension strip 431 fixedly connected. A slide rail 432 is arranged at the top of the extension strip 431. A blocking member 4321 is arranged on the top of the slide rail 432. The blocking member 4321 is slidably connected to the top of the slide rail 432. Among them: on the side of the reciprocating fixing plate 43 away from the extension strip 431, there is a first sliding member 44 slidably connected. On one side of the first sliding member 44, there is a first protruding column 441 fixedly connected. On the top of the first sliding member 44, there is a second protruding column 442 fixedly connected. On both sides of the periphery of the top of the first sliding member 44, there are blocking columns 443 fixedly connected.

[0046] The outer wall of the No. 1 raised column 441 is rotatably connected to the No. 1 connecting rod 45, and the top of one end of the No. 1 connecting rod 45 is fixedly connected to the No. 3 raised column 451, and the other end of the No. 1 connecting rod 45 is fixedly connected to the No. 2 sliding member 452, and the outer walls of the No. 2 sliding member 452 on both sides are provided with threaded grooves 4521, and the directions of the threaded grooves 4521 on both sides correspond to the No. 1 threaded rod 411 and the No. 2 threaded rod 421 respectively, and the threaded grooves 4521 on both sides are respectively matched with the No. 1 threaded rod 411 and the No. 2 threaded rod 421, and the bottom of the No. 2 sliding member 452 is fixedly connected to one end of the telescopic rod 453, and the other end of the telescopic rod 453 is fixedly connected to the reciprocating paddle 454.

[0047] The outer wall of the No. 2 raised column 442 is rotatably connected to a toggle assembly 46, and the toggle assembly 46 includes an extension rod 461. The outer wall of the extension rod 461 is provided with an arch hole 4611, and the width of the arch hole 461 matches the diameter of the No. 3 raised column 451, and the extension rod 461 is facing the direction of the No. 3 raised column 451. The toggle assembly 46 includes a No. 2 connecting rod 462, one end of the No. 2 connecting rod 462 is fixedly connected to one end of the extension rod 461, and the No. 2 connecting rod 462 and the extension rod 461 are vertically distributed, and the No. 2 connecting rod 462 is fixedly connected to the No. 4 raised column 463 at the top of the end away from the No. 2 raised column 442.

[0048] The outer wall of the No. 2 raised column 442 is rotatably connected to the No. 3 connecting rod 47, the connection between the No. 3 connecting rod 47 and the No. 2 raised column 442 is located at the top of the toggle assembly 46, the middle end of the No. 3 connecting rod 47 is located between the blocking columns 443 on both sides, and the No. 5 raised column 471 is fixedly connected to the top of the end of the No. 3 connecting rod 47 away from the No. 2 raised column 442, and a spring 48 is fixedly connected between the No. 5 raised column 471 and the No. 4 raised column 463.

[0049] From this we can see that Figures 6-9 As shown, under the drive of the motor 41, the first threaded rod 411 rotates, and at the same time drives the first gear 412 to rotate, and the first gear 412 drives the second gear 42 and the second threaded rod 421 to rotate, as shown in FIG. Figure 7 As shown, during the rotation of the No. 2 threaded rod 421, the No. 2 sliding member 452 which is in close contact with the No. 2 threaded rod 421 will be driven to slide from right to left. During the sliding of the No. 2 sliding member 452, the No. 1 sliding member 44 will be driven to slide from right to left. At the same time, the No. 3 connecting rod 47 on the top of the No. 1 sliding member 44 will also slide. At this time, the middle end of the No. 3 connecting rod 47 is blocked by the left blocking column 443. When the No. 1 sliding member 44 and the No. 2 sliding member 452 slide to the position of the left blocking member 4321, the No. 3 connecting rod 47 will be blocked by the blocking member 4321 at the end close to the No. 5 protruding column 471, and the No. 5 protruding column 471 will be pushed to the right until the No. 3 connecting rod 47 is against the blocking column 443 on the right.

[0050] At the same time, because the extension rod 461 is restricted by the third protruding column 451 and the first sliding member 44, the toggle assembly 46 can only rotate clockwise by a certain angle. At the same time, the clockwise rotation of the extension rod 461 will cause the third protruding column 451 to rotate counterclockwise by a certain angle due to the restriction of the arch hole 4611 on the third protruding column 451. At the same time, the first connecting rod 45 and the second sliding member 452 will also rotate counterclockwise by a certain angle. At this time, the left thread groove 4521 of the second sliding member 452 is separated from the second threaded rod 421 during the counterclockwise rotation, and the right thread groove 4521 is attached to the first threaded rod 411. At this time, the first threaded rod 411 is driven by the motor 41 to rotate, which will drive the second sliding member 452 and the first sliding member 44 to move to the right side until they reach the position of the right blocking member 4321. Similarly, it moves from right to left again, thereby realizing the continuous transportation of the rod material by left and right reciprocating sliding, without the need for human operation, and can ensure the safety of the staff.

[0051] It should be noted that, in the process that the No. 1 threaded rod 411 and the No. 2 threaded rod 421 drive the No. 1 sliding member 44 and the No. 2 sliding member 452 to slide back and forth left and right, the reciprocating paddle 454 at the bottom of the No. 2 sliding member 452 is at the inner edge position of the No. 1 conveying track 22 in the process that the No. 2 threaded rod 421 drives the No. 2 sliding member 452 to slide from right to left, and under the action of the spring 48, when the No. 1 connecting rod 45 drives the No. 2 sliding member 452 to rotate counterclockwise, it will also drive the reciprocating paddle 454 to rotate counterclockwise by a certain angle. When the thread groove 4521 is in contact with the No. 1 threaded rod 411, the position of the reciprocating paddle 454 is exactly at the top of the semicircular groove 221. At this time, the rods transported to the top of the semicircular groove 221 by the tapered roller 2221 can be pushed into the V-shaped groove 231 by the reciprocating paddle 454 for stacking, sorting and grinding.

[0052] The above shows and describes the basic principles, main features and advantages of the present invention.
