[0026] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0028] Reference Figure 1-7, a replacement parts stacking device for laser cutting equipment, including a rectangular frame 1, which is the main structure of the device and provides a support platform for the components arranged thereon. Two conveyor belts 2 are vertically, parallel and symmetrically arranged at both ends of the rectangular frame 1, that is, the planes of the two conveyor belts 2 are arranged opposite to each other. And a cross bar 3 is installed horizontally between the two conveyor belts 2 at the same end, and a tray 4 is placed horizontally on the two cross bars 3, that is, the two cross bars 3 at both ends support the bottom ends of the tray 4. The tray 4 is used to place replacement parts for the equipment. The rectangular frame 1 is provided with a driving mechanism for driving the corresponding conveyor belt 2, and the driving mechanism can accurately drive the two conveyor belts 2 to transmit.

[0029] As a technical optimization solution of the present invention, a plurality of through holes 5 are provided on the conveyor belt 2, and the plurality of through holes 5 on one conveyor belt 2 are aligned in pairs. Threaded rods 6 are coaxially fixed to both ends of the crossbar 3, and the two threaded rods 6 are respectively inserted into the through holes 5 of the two conveyor belts 2. The radius of the crossbar 3 is larger than the radius of the through hole 5. The threaded rods 6 are threadedly connected with nuts 7. The crossbar 3 can be tightened and fixed between the two conveyor belts 2 through the two threaded rods 6 and the corresponding nuts 7. When setting the crossbar 3, the threaded rods 6 at both ends of the crossbar 3 are respectively inserted into the two through holes 5 aligned with the two corresponding conveyor belts 2, and then the fixing nuts 7 are respectively screwed on and tightened. The nuts 7 at both ends squeeze the corresponding conveyor belts 2, thereby fixing the crossbar 3 in between. At this time, the crossbar 3 remains in a horizontal state. When the two corresponding conveyor belts 2 are started synchronously, the crossbar 3 can be accurately driven to rise and fall in the horizontal position. At the same time, the arrangement of four conveyor belts 2 and the corresponding arrangement of several through holes 5 enable multiple cross bars 3 to be arranged above and below between the two conveyor belts 2, so that corresponding multi-layer pallets 4 can be arranged, that is, more quantity effects can be achieved, or different batches of equipment replacement parts can be placed in a classified manner.

[0030] For the above examples, those skilled in the art should know that when implementing the above technical solution, it is not limited to setting up a conveyor belt 2 to lift the cross bar 3 in between, and the conveyor belt 2 can also be replaced by a chain or a chain belt.

[0031] As a technical optimization solution of the present invention, a platform is cut in the middle of the cross bar 3, the tray 4 is rectangular, and the two ends of the bottom of the tray 4 are respectively placed against the platforms of the two cross bars 3, and the platform provides stable support for the tray 4.

[0032] As a technical optimization solution of the present invention, the tray 4 is located inside the rectangular frame 1, the length of the tray 4 is the same as the internal length of the rectangular frame 1, and the width of the tray 4 is the same as the internal width of the rectangular frame 1. After the tray 4 is placed, it can be effectively restricted by the rectangular frame 1.

[0033] As a technical optimization solution of the present invention, the drive mechanism includes two brackets 8 fixed at the top ends of a rectangular frame 1, two first rotating rods 9 are symmetrically rotated between the two brackets 8, and two second rotating rods 10 are symmetrically rotated at the bottom of the rectangular frame 1. Two drive pulleys 20 are symmetrically fixed on each of the first rotating rod 9 and the second rotating rod 10, that is, two drive pulleys 20 are coaxially fixed at both ends of the first rotating rod 9, and two drive pulleys 20 are symmetrically fixed at both ends of the second rotating rod 10. The transmission belt 2 is driven at both ends by two drive pulleys 20 arranged in an upper and lower alignment, that is, the transmission belt 2 is driven at both ends of the first rotating rod 9 and the second rotating rod 10 arranged in an upper and lower alignment. A motor 11 for driving the rotation of the first rotating rod 9 is fixed to the side of the bracket 8. The motor 11 is coaxially fixedly connected to the first rotating rod 9 via a power output shaft.

[0034] For the above example, those skilled in the art should know that when implementing the above technical solution, it is not limited to setting up a motor 11 to drive the rotation, and a crank fixed coaxially with the first rotating rod 9 can also be set to drive the rotation by manual hand cranking.

[0035] As a technical optimization solution of the present invention, two meshing and matching gears 12 are symmetrically rotated on one side of the bracket 8. The two gears 12 are coaxially fixed with a first pulley 13. The two first rotating rods 9 are coaxially fixed with a second pulley 14. The two first pulleys 13 are respectively connected to the two second pulleys 14 through belt transmission. The arrangement of the two gears 12 means that when one first rotating rod 9 rotates, the first rotating rod 9 can drive the corresponding second pulley 14 to rotate, and the second pulley 14 drives the corresponding first pulley 13 to rotate, and the first pulley 13 drives the corresponding gear 12 to rotate, and the gear 12 drives another gear 12 to rotate, and finally drives the other first rotating rod 9 to rotate. At this time, the meshing effect of the two gears 12 makes the rotation directions opposite, that is, the two first rotating rods 9 rotate in opposite directions.

[0036] As a technical optimization solution of the present invention, a slider 15 is provided on one side of the bracket 8 for horizontal sliding. A pawl block 16 rotates on the slider 15. A torsion spring is installed on the rotating shaft of the pawl block 16, which causes the pawl block 16 to rotate downward. A ratchet 17 is coaxially fixed to a first rotating rod 9, and the ratchet 17 engages with the pawl block 16. The end of the slider 15 facing away from the ratchet 17 is fixedly connected to the bracket 8 via a spring 18. The spring 18 pushes the slider 15 toward the ratchet 17, that is, pushes the pawl block 16 toward the ratchet 17. A stop block 21 is fixed to the bracket 8 below the slider 15. The stop block 21 is used to abut and restrict the pawl block 16. The stop block 21 is used to support and restrict the pawl block 16, so that the pawl block 16 can effectively engage with the ratchet 17.

[0037] As a technical optimization solution of the present invention, the rectangular frame 1 is provided with a dust cover 19, the opening of the dust cover 19 faces upward, and the opening edge of the dust cover 19 is detachably fixedly connected to the four conveyor belts 2. The dust cover 19 can wrap the rectangular frame 1 as a whole from the bottom, playing a dustproof and waterproof effect, and can effectively protect the replacement parts inside. The opening of the dust cover 19 can be fixed to the conveyor belt 2, and the opening of the dust cover 19 can rise as the conveyor belt 2 is driven, so that the whole is unfolded or lowered to expose the rectangular frame 1. Therefore, when the cross bar 3 and the corresponding tray 4 rise, the end of the dust cover 19 will fall accordingly, exposing the internal rectangular frame 1, which is convenient for taking and placing the replacement parts on the tray 4. After taking and placing, when the cross bar 3 and the corresponding tray 4 fall, the end of the dust cover 19 will rise accordingly, so that the whole is unfolded to wrap the rectangular frame 1 inside.

[0038] In the present invention, the working principle of the device is as follows:

[0039] First, set the crossbar 3 and the tray 4 on the rectangular frame 1. When setting the crossbar 3, insert the threaded rods 6 at both ends of the crossbar 3 into the two through holes 5 aligned with the two corresponding conveyor belts 2, and then screw on and tighten the fixing nuts 7. The nuts 7 at both ends squeeze the corresponding conveyor belts 2, thereby fixing the crossbar 3 in between. At this time, the crossbar 3 remains in a horizontal state. When the two corresponding conveyor belts 2 are started synchronously, the crossbar 3 can be accurately driven to rise and fall in the horizontal position. After that, the tray 4 can be placed horizontally on the two symmetrical crossbars 3. At the same time, the setting of four conveyor belts 2 and the corresponding setting of several through holes 5 enable multiple crossbars 3 to be set up and down between the two conveyor belts 2. Therefore, multiple layers of trays 4 can be set accordingly, which can achieve a larger number of effects, or classify and place equipment replacement parts from different batches. When replacement parts are needed, they can be taken directly from the tray 4.

[0040] After setting up several trays 4, they can be taken from the upper tray 4. When the replacement parts on the upper layer are taken out, the motor 11 can be started to control a first rotating rod 9 to rotate. The first rotating rod 9 can drive the corresponding second pulley 14 to rotate, and the second pulley 14 drives the corresponding first pulley 13 to rotate. The first pulley 13 drives the corresponding gear 12 to rotate, and the gear 12 drives another gear 12 to rotate, and finally drives another first rotating rod 9 to rotate. At this time, the meshing effect of the two gears 12 makes the rotation directions opposite, that is, the two first rotating rods 9 rotate in opposite directions. At this time, several trays 4 can be controlled to move upward, and the bottom tray 4 can be raised to a height where the replacement parts can be easily taken out, which effectively improves the convenience of taking. The overall work efficiency is higher, and the replacement parts at the bottom can be more conveniently taken out for use.

[0041] A dust cover 19 can also be provided. The dust cover 19 can wrap around the bottom of the rectangular frame 1, providing dust and water resistance, and effectively protecting the replacement parts inside. The opening of the dust cover 19 is fixed to the conveyor belt 2. When the crossbar 3 and the corresponding tray 4 rise, that is, when the conveyor belt 2 is driven, the end of the dust cover 19 falls, exposing the internal rectangular frame 1, making it easy to take and place the replacement parts on the tray 4. After taking and placing, when the crossbar 3 and the corresponding tray 4 fall, the conveyor belt 2 continues to drive, and the end of the dust cover 19 rises, thereby expanding the entire frame 1 to wrap around the interior.

[0042] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
