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? 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

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 bidirectional tilting mechanism 202 is installed on the first side plate 3; The guide trigger mechanism 303 is used to cooperate with the bidirectional tilting mechanism 202 so that the steel ball can be accurately and compactly placed in the packaging box 10. The guide trigger mechanism 303 is installed on the double-layer packaging mechanism 101; And the mobile unloading mechanism 404 is used to control the single discharging of steel balls, and the mobile unloading mechanism 404 is installed on the double-layer packaging mechanism 101.

The ends of the two tilting push rods 21 are respectively fixedly connected to the upper layer connecting rod 19 and the lower layer connecting rod 20. The end of the upper layer connecting rod 19 is fixedly connected to the upper layer pressure rod 25, and the end of the lower layer connecting rod 20 is fixedly connected to the lower layer pressure rod 29.

[0023] In this embodiment, the ball outlet bin 11 can be connected to the discharge port of the steel balls. In the initial state, the transfer frame 7 is horizontal, that is, the main slide bar 15 has not pressed the lower laminating rod 29 or the upper laminating rod 25. When the first motor 2 drives the main conveyor belt 1 to move through the main transmission roller 4 to convey the packaging box 10 to the auxiliary conveyor belt 17, the packaging box 10 is first stationary, and the ball outlet cavity 12 first places the steel balls on the bottom layer of the packaging box 10. Since the steel balls themselves have rolling properties, when the drive motor 27 rotates to drive the drive gear 28 to slide along the tooth block group 26, the main slide bar 15 will slide in the circular track 14. The main slide bar 15 is set as follows. Figure 4 The main slide bar 15 slides counterclockwise along the circular track 14. When the main slide bar 15 presses the lower lamination bar 29, the lower lamination bar 29 drives the lower connecting bar 20 to move downward, so that the lower connecting bar 20 presses a tilting push rod 21, so that the tilting push rod 21 drives 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 in the packaging box 10 in a scattered manner.

[0024] 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.

[0025] 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 first side plate 3 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, and the contact plate 13 is fixedly connected to the circular track 14.

[0026] 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.

[0027] 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.

[0028] 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.

[0029] In this embodiment, when the corrugated guide tube 32 is extended, the steel balls are set to be placed in rows, so the driving motor 27 will stop after reaching the specified position, and the fourth motor 42 drives the fourth gear 43 to rotate, so that the fourth gear 43 engages with the fourth rack 46, driving the ball outlet cavity 12 to slide, so that when the third rack 40 passes through the protrusion of the unloading slide rail 44, it will move downward and drive the third gear 41 and the single unloading barrel 45 to rotate. The single unloading barrel 45 can carry a steel ball inside, so that a single ball can be placed and packaged accurately, thereby improving the tightness of the steel balls.

[0030] The driving motor 27 continues to move until all the steel balls are placed on the bottom layer, and the main slide bar 15 moves to the turning point of the circular track 14. At this time, the lower pressure rod 29 is no longer under pressure, so the transfer frame 7 is restored to a horizontal state by the elastic force of the first spring 23. When the main slide bar 15 presses the upper pressure rod 25, the upper pressure rod 25 moves downward, thereby driving the transfer frame 7 to tilt in another direction. Since the bottom layer is already full of steel balls at this time, there are restrictions between the steel balls. When the transfer frame 7 is tilted at a small angle, the steel balls cannot fall off.

[0031] After the steel balls are placed on the upper layer, the main slide bar 15 moves to the turning point of the return track 14, and the transfer frame 7 regains balance again. The second motor 8 drives the auxiliary conveyor belt 17 to rotate through the auxiliary transmission roller 24 to transport the packaging box 10 filled with steel balls. When the L-shaped rod 39 contacts the contact plate 13, the contact plate 13 drives the L-shaped rod 39 to move upward, thereby driving the second gear 36 and the first gear 34 to reverse, so that the first slide rail 31 is reset, the third slide bar 33 moves upward, and the corrugated guide tube 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 contact plate 13 will not continue to contact the L-shaped rod 39.

[0032] The specific working principle and use method of the present invention are explained in detail below: when in use, the ball outlet bin 11 can be connected to the discharge port of the steel ball. In the initial state, the transfer frame 7 is horizontal, that is, the main slide bar 15 has not yet pressed the lower lamination rod 29 or the upper lamination rod 25. When the first motor 2 drives the main conveyor belt 1 to move through the main transmission roller 4 to convey the packaging box 10 to the auxiliary conveyor belt 17, the packaging box 10 is first stationary, and the ball outlet cavity 12 first places the steel ball on the bottom layer of the packaging box 10. Since the steel ball itself has rolling properties, when the drive motor 27 rotates to drive the drive gear 28 to slide along the tooth block group 26, the main slide bar 15 will slide in the circular track 14. The main slide bar 15 is set as follows: Figure 4The main slide bar 15 slides counterclockwise along the circular track 14. When the main slide bar 15 presses the lower lamination bar 29, the lower lamination bar 29 drives the lower connecting bar 20 to move downward, so that the lower connecting bar 20 presses a tilting push rod 21, so that the tilting push rod 21 drives 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 in the packaging box 10 in a scattered manner.

[0033] At the same time, before the main slide bar 15 presses the lower laminating rod 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 move smoothly to the top of the packaging box 10. When the main slide bar 15 presses the lower laminating rod 29, the lower laminating rod 29 will press the L-shaped rod 39, so that the L-shaped rod 39 drives the second gear 36 and the first gear 34 to rotate through the second tooth 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.

[0034] When the corrugated guide tube 32 is extended, the steel balls are set to be placed in rows, so the driving motor 27 will stop after reaching the specified position, and the fourth motor 42 drives the fourth gear 43 to rotate, so that the fourth gear 43 engages with the fourth rack 46, driving the ball outlet cavity 12 to slide, so that when the third rack 40 passes through the protrusion of the unloading slide rail 44, it will move downward and drive the third gear 41 and the single unloading barrel 45 to rotate. The single unloading barrel 45 can carry a steel ball inside, so that a single ball can be placed and packaged accurately, thereby improving the tightness of the steel balls.

[0035] The driving motor 27 continues to move until all the steel balls are placed on the bottom layer, and the main slide bar 15 moves to the turning point of the circular track 14. At this time, the lower pressure rod 29 is no longer under pressure, so the transfer frame 7 is restored to a horizontal state by the elastic force of the first spring 23. When the main slide bar 15 presses the upper pressure rod 25, the upper pressure rod 25 moves downward, thereby driving the transfer frame 7 to tilt in another direction. Since the bottom layer is already full of steel balls at this time, there are restrictions between the steel balls. When the transfer frame 7 is tilted at a small angle, the steel balls cannot fall off.

[0036] After the steel balls are placed on the upper layer, the main slide bar 15 moves to the turning point of the return track 14, and the transfer frame 7 regains balance again. The second motor 8 drives the auxiliary conveyor belt 17 to rotate through the auxiliary transmission roller 24 to transport the packaging box 10 filled with steel balls. When the L-shaped rod 39 contacts the contact plate 13, the contact plate 13 drives the L-shaped rod 39 to move upward, thereby driving the second gear 36 and the first gear 34 to reverse, so that the first slide rail 31 is reset, the third slide bar 33 moves upward, and the corrugated guide tube 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 contact plate 13 will not continue to contact the L-shaped rod 39.

[0037] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are conventional means well known to those skilled in the art.

[0038] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
