Description

Technical Field

[0001] The invention relates to the technical field of steel ball packaging, in particular to an automatic counting and packaging device for steel balls. Background Art

[0002] Steel ball is a spherical iron alloy wear-resistant body produced by forging, spinning, rolling and casting. It is the most important component of today's crushing industrial mining balls, cement balls, etc. In the process of factory sales of existing steel balls, in order to ensure the convenience of steel ball transportation, it is very necessary to use a steel ball packaging machine.

[0003] The patent with publication number: CN117963211A discloses a wear-resistant ball quantitative packaging equipment and a packaging method thereof, including a counting component, a material dividing component, a material discharging component and a bag holding component; the material dividing component includes a steel ball receiving and guiding component, a first discharging channel, a second discharging channel and a rotating shielding and channel changing component; the discharging end of the steel ball receiving and guiding component is connected with a first discharging channel and a second discharging channel arranged in parallel with each other, and a rotating shielding and channel changing component is installed on one side of the second discharging channel of the steel ball receiving and guiding component. When the rotating shielding and channel changing component is expanded, the second discharging channel is shielded and closed, and the first discharging channel is opened. When the rotating shielding and channel changing component is retracted, the first discharging channel is shielded and closed, and the second discharging channel is opened.

[0004] However, the above invention patent still has some shortcomings in actual use: 1. The counting component is set to count the steel balls. When the count reaches 95 steel balls, the steel balls are blocked through a series of transmission components and then unloaded in sequence to achieve the purpose of packaging 100 steel balls. Why not directly block the subsequent steel balls at 100 steel balls?

[0005] 2. In the prior art, steel balls are packaged in boxes or bags. However, in order to avoid wear and tear caused by shaking and collision with the inner wall of the box during transportation, the size of the box is generally the same as the overall volume of the steel balls. That is to say, the height of the steel balls after packaging will be the same as the height of the box. This makes it impossible to ensure the tightness of the steel balls when they fall into the box due to the rotation and uncertainty of the steel balls themselves. There is no extra space in the box, and the internal limitations can easily cause the steel balls to accumulate and fall off, or the steel balls are not arranged tightly enough, resulting in deviations in the packaging quantity. Therefore, an automatic counting and packaging equipment for steel balls is proposed to solve the above-mentioned problems. Summary of the invention

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0033] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0034] Refer to Figures 1-9 , an automatic steel ball counting and packaging device, including a first side plate 3 and a second side plate 9. Two evenly distributed main transmission rollers 4 are rotatably connected between the first side plate 3 and the second side plate 9.

A first shaft rod 22 is rotatably connected to the inner wall of the first side plate 3. A transfer frame 7 is fixedly connected to the end of the first shaft rod 22. Two auxiliary transmission rollers 24 are rotatably connected to the inner wall of the transfer frame 7. An auxiliary conveyor belt 17 is sleeved on the outer walls of the two auxiliary transmission rollers 24. A packaging box 10 is arranged on the auxiliary conveyor belt 17.

It further includes:

[0035] A double-layer packaging mechanism 101 for placing steel balls in a double layer in the packaging box 10. The double-layer packaging mechanism 101 is installed on the first side plate 3;

[0036] A two-way tilting mechanism 202 for cooperating with the movement of the double-layer packaging mechanism 101. When the double-layer packaging mechanism 101 moves on the lower layer of the return track 14, the transfer frame 7 tilts, and when the double-layer packaging mechanism 101 moves on the upper layer of the return track 14, the transfer frame 7 tilts in the opposite direction. The two-way tilting mechanism 202 is installed on the first side plate 3;

[0037] A guiding and triggering mechanism 303 for cooperating with the two-way tilting mechanism 202 to enable the steel balls to be accurately and compactly placed in the packaging box 10. The guiding and triggering mechanism 303 is installed on the double-layer packaging mechanism 101;

[0038] And a moving and feeding mechanism 404 for controlling the single-piece discharge of steel balls. The moving and feeding mechanism 404 is installed on the double-layer packaging mechanism 101.

[0039] Among them, five limiting shaft rods 18 are rotatably connected between the first side plate 3 and the second side plate 9. The outer walls of the two main transmission rollers 4 and the five limiting shaft rods 18 are sleeved with the same main conveyor belt 1. A second motor 8 is fixedly connected to the outer wall of the transfer frame 7, and the output shaft of the second motor 8 is fixedly connected to one of the auxiliary transmission rollers 24.

[0040] Among them, the double-layer packaging mechanism 101 includes a first sliding rod 5, a second sliding rod 6, a tooth block group 26, a driving motor 27, a driving gear 28, a main sliding rod 15 and a mounting rod 16. The tooth block group 26 is fixedly connected to the loop track 14. The main sliding rod 15 is slidably connected to the loop track 14. The mounting rod 16 is fixedly connected to the main sliding rod 15. The end of the first sliding rod 5 is fixedly connected to the mounting rod 16. The outer wall of the first sliding rod 5 is slidably connected to the second sliding rod 6. The second sliding rod 6 is slidably connected to the second side plate 9. The driving gear 28 is rotatably connected to the end of the main sliding rod 15. The output shaft of the driving motor 27 is fixedly connected to the driving gear 28. The driving gear 28 meshes with the tooth block group 26.

[0041] Among them, the double-direction inclined mechanism 202 includes a lower pressing rod 29, a lower connecting rod 20, an upper pressing rod 25, an upper connecting rod 19, two inclined push rods 21 and two first springs 23. The two inclined push rods 21 are both slidably connected to the first side plate 3. The two first springs 23 are fixedly connected between the first shaft rod 22 and the first side plate 3. The ends of the two inclined push rods 21 are respectively fixedly connected to the upper connecting rod 19 and the lower connecting rod 20. The end of the upper connecting rod 19 is fixedly connected to the upper pressing rod 25. The end of the lower connecting rod 20 is fixedly connected to the lower pressing rod 29.

[0042] In this implementation scheme, the ball outlet bin 11 can be connected to the steel ball discharge port. In the initial state, the transfer frame 7 is horizontal, that is to say, the main sliding rod 15 has not pressed the lower pressing rod 29 or the upper pressing rod 25 yet. When the first motor 2 drives the main conveyor belt 1 to move through the main transmission roller 4 and conveys the packaging box 10 onto the auxiliary conveyor belt 17, the packaging box 10 first remains stationary. The ball outlet cavity 12 first places steel balls on the bottom layer of the packaging box 10. Due to the rolling property of the steel balls themselves, when the driving motor 27 rotates to drive the driving gear 28 to slide along the tooth block group 26, the main sliding rod 15 will slide within the loop track 14. Assume that the main sliding rod 15 Figure 4 slides counterclockwise along the loop track 14 in a certain direction. When the main sliding rod 15 presses the lower pressing rod 29, the lower pressing rod 29 drives the lower connecting rod 20 to move downward, so that the lower connecting rod 20 presses one of the inclined push rods 21, causing the inclined push rod 21 to drive the transfer frame 7 and the packaging box 10 to tilt at a certain angle, so that when the steel balls fall into the packaging box 10, they will approach one side and will not fall into the packaging box 10 dispersedly.

[0043] Among them, the guide trigger mechanism 303 includes a first gear 34, a first rack 35, a second gear 36, a mounting frame 37, a second tooth plate 38 and an L-shaped rod 39. The L-shaped rod 39 is slidingly connected to the mounting rod 16, the second tooth plate 38 is fixedly connected to the L-shaped rod 39, the mounting frame 37 is fixedly connected to the mounting rod 16, the second gear 36 is rotatably connected to the mounting frame 37, the second gear 36 is meshed with the second tooth plate 38, the first gear 34 is fixedly connected to the second gear 36 through a set shaft, and the first gear 34 is meshed with the outer wall of the first rack 35.

[0044] Among them, the guide trigger mechanism 303 also includes a first slide rail 31, a corrugated guide tube 32, a third slide rod 33 and a contact plate 13. The third slide rod 33 is arranged in the mounting rod 16. The end of the third slide rod 33 is slidingly connected to the first slide rail 31. The first slide rail 31 is fixedly connected to the first rack 35. The third slide rod 33 is fixedly connected to the corrugated guide tube 32. The end of the corrugated guide tube 32 is fixedly connected to the ball outlet cavity 12. The contact plate 13 is fixedly connected to the circular track 14.

[0045] In the present embodiment, before the main slide bar 15 presses the lower laminating bar 29, the corrugated guide tube 32 is retracted at the bottom end of the ball outlet cavity 12 by default, so the ball outlet cavity 12 can be smoothly moved to the top of the packaging box 10. When the main slide bar 15 presses the lower laminating bar 29, the lower laminating bar 29 will press the L-shaped bar 39, so that the L-shaped bar 39 drives the second gear 36 and the first gear 34 to rotate through the second gear plate 38, thereby driving the first rack 35 and the first slide rail 31 to move, so that the third slide bar 33 slides down along the inclined surface of the first slide rail 31, so that the corrugated guide tube 32 extends into the packaging box 10, so that the distance between the bottom end of the corrugated guide tube 32 and the packaging box 10 is only enough to accommodate the diameter of a steel ball, so that the steel ball can be accurately delivered.

[0046] Among them, the mobile unloading mechanism 404 includes a ball outlet bin 11, a ball outlet cavity 12, a fourth motor 42, a fourth gear 43 and a fourth rack 46. The ball outlet bin 11 is fixedly connected to the ball outlet cavity 12, the fourth motor 42 is fixedly connected to the ball outlet cavity 12, the fourth gear 43 is fixedly connected to the output shaft of the fourth motor 42, the fourth rack 46 is fixedly connected to the mounting rod 16, and the fourth rack 46 is meshed with the outer wall of the fourth gear 43.

[0047] Among them, the mobile unloading mechanism 404 also includes a third rack 40, a third gear 41, an unloading slide 44 and a single unloading barrel 45. The unloading slide 44 is fixedly connected to the mounting rod 16, the third rack 40 is slidably connected to the unloading slide 44, the third rack 40 is meshed with the third gear 41, and the third gear 41 is fixedly connected to the single unloading barrel 45 through a set shaft.

[0048] In this implementation, after the corrugated guide tube 32 extends out, the steel balls are arranged in rows. Therefore, when the driving motor 27 reaches the designated position, it will stop. The fourth motor 42 drives the fourth gear 43 to rotate, causing the fourth gear 43 to mesh with the fourth rack 46, driving the ball outlet cavity 12 to slide. As a result, when the third rack 40 passes through the protrusion of the blanking slide rail 44, it will move downward to drive the third gear 41 and the single blanking cylinder 45 to rotate. The single blanking cylinder 45 can hold one steel ball, accurately achieving single-piece placement and packaging, and improving the compactness of the steel balls.

[0049] When the driving motor 27 continues to move until all the steel balls are placed at the bottom layer, the main slide rod 15 moves to the turning point of the return track 14. At this time, the lower pressing rod 29 is no longer pressed, so the transfer frame 7 returns to the horizontal under the elastic force of the first spring 23. When the main slide rod 15 presses the upper pressing rod 25, the upper pressing rod 25 moves downward, driving the transfer frame 7 to tilt in the other direction. Since the bottom layer is already filled with steel balls at this time and there is a restriction between the steel balls, the steel balls cannot fall off when the tilt angle of the transfer frame 7 is small.

[0050] After the steel balls are placed on the upper layer, the main slide rod 15 moves to the turning point of the return track 14, and the transfer frame 7 returns to balance again. The second motor 8 drives the secondary conveyor belt 17 to rotate through the secondary drive roller 24 to convey away the packaging box 10 filled with steel balls. When the L-shaped rod 39 abuts against the abutting plate 13, the abutting plate 13 drives the L-shaped rod 39 to move upward, driving the second gear 36 and the first gear 34 to reverse, causing the first slide rail 31 to reset and the third slide rod 33 to move upward, and the corrugated guide tube 32 to contract to facilitate packaging the next box of steel balls. Since the end of the return track 14 is arc-shaped, the abutting plate 13 will not continuously abut against the L-shaped rod 39.

[0051] The following is a detailed explanation of the specific working principle and usage method of the present invention: During use, the ball outlet bin 11 can be connected to the outlet of the steel balls. In the initial state, the transfer frame 7 is horizontal, that is, the main slide rod 15 has not yet pressed the lower pressing rod 29 or the upper pressing rod 25. When the first motor 2 drives the main conveyor belt 1 to move through the main drive roller 4 to convey the packaging box 10 onto the secondary conveyor belt 17, the packaging box 10 first remains stationary, and the ball outlet cavity 12 first places the steel balls on the bottom layer of the packaging box 10. Due to the rolling nature of the steel balls themselves, when the driving motor 27 rotates to drive the driving gear 28 to slide along the tooth block group 26, the main slide rod 15 will slide within the return track 14. Assuming the main slide rod 15 is as Figure 4It slides counterclockwise along the looped track 14. When the main slide bar 15 presses down on the lower layer pressure bar 29, the lower layer pressure bar 29 drives the lower layer connecting rod 20 to move downward, so that the lower layer connecting rod 20 presses down on an inclined push rod 21, causing the inclined push rod 21 to drive the transfer frame 7 and the packaging box 10 to tilt at a certain angle, so that when the steel balls fall into the packaging box 10, they will move closer to one side and will not fall into the packaging box 10 dispersedly.

[0052] At the same time, before the main slide bar 15 presses down on the lower layer pressure bar 29, the corrugated guide tube 32 is defaultly contracted at the bottom of the ball outlet cavity 12, so the ball outlet cavity 12 can smoothly move above the packaging box 10. When the main slide bar 15 presses down on the lower layer pressure bar 29, the lower layer pressure bar 29 will press down on the L-shaped rod 39, causing the L-shaped rod 39 to drive the second gear 36 and the first gear 34 to rotate through the second toothed plate 38, thereby driving the first rack 35 and the first slide rail 31 to move, so that the third slide bar 33 slides down along the inclined plane of the first slide rail 31, so that the corrugated guide tube 32 extends into the packaging box 10, and the distance between the bottom end of the corrugated guide tube 32 and the packaging box 10 is only enough to accommodate the diameter of a steel ball, achieving precise delivery of the steel balls.

[0053] After the corrugated guide tube 32 extends out, assuming the steel balls are arranged in rows, the drive motor 27 will stop after reaching the designated position. The fourth motor 42 drives the fourth gear 43 to rotate, causing the fourth gear 43 to mesh with the fourth rack 46, driving the ball outlet cavity 12 to slide. Thus, when the third rack 40 passes through the protruding part of the blanking slide rail 44, it will move downward to drive the third gear 41 and the single blanking cylinder 45 to rotate. The single blanking cylinder 45 can carry one steel ball inside, achieving precise single-piece placement and packaging, and improving the compactness of the steel balls.

[0054] The drive motor 27 continues to move until all the steel balls are placed at the bottom layer. The main slide bar 15 moves to the turning point of the looped track 14. At this time, the lower layer pressure bar 29 is no longer under pressure, so the transfer frame 7 returns to the horizontal under the elastic force of the first spring 23. When the main slide bar 15 presses down on the upper layer pressure bar 25, the upper layer pressure bar 25 moves downward, thereby driving the transfer frame 7 to tilt in the other direction. Since the bottom layer is already full of steel balls at this time and there is a restriction between the steel balls, when the inclination angle of the transfer frame 7 is small, the steel balls cannot fall off.

[0055] After the upper layer places the steel balls, the main sliding rod 15 moves to the turning point of the return track 14, and the transfer box 7 regains balance again. The second motor 8 drives the secondary conveyor belt 17 to rotate through the secondary transmission roller 24 to convey the packaging box 10 filled with steel balls away. When the L-shaped rod 39 abuts against the abutting plate 13, the abutting plate 13 drives the L-shaped rod 39 to move upward, thereby driving the second gear 36 and the first gear 34 to reverse, causing the first slide rail 31 to reset and the third sliding rod 33 to move upward. The corrugated guide pipe 32 contracts to facilitate the packaging of the next box of steel balls. Since the end of the return track 14 is arc-shaped, the abutting plate 13 will not continuously abut against the L-shaped rod 39.

[0056] Further explanation, the above fixed connection, unless otherwise clearly specified and limited, should be understood in a broad sense. For example, it can be welding, gluing, or integrally formed setting, etc., which are common means well-known to those skilled in the art.

[0057] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
