Description

Technical Field

[0001] This utility model relates to the field of laser cutting, specifically to an automatic feeding mechanism for a precision laser cutting machine. Background Technology

[0002] A laser cutting machine focuses the laser emitted from a laser source into a high-power-density laser beam through an optical path system.

[0003] In the existing technology, laser cutting machines are common cutting tools with advantages such as high precision, high efficiency and environmental friendliness. The operator places the item to be cut on the cutting table, and then cuts it through the movable laser head above the cutting table to obtain the required size.

[0004] However, most laser cutting machines require manual loading, and after each cut, workers need to move the items to be cut to the cutting table, which is time-consuming and laborious and does not improve cutting efficiency. Utility Model Content

[0005] The purpose of this invention is to provide an automatic feeding mechanism for a precision laser cutting machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic feeding mechanism for a precision laser cutting machine, the automatic feeding mechanism for a precision laser cutting machine comprising:

[0007] The motor has a storage tube fixed to its output end, a first transmission wheel fixed to the bottom side surface of the storage tube, a transmission belt sleeved on the outer surface of the first transmission wheel, a threaded hole inside the storage tube, the threaded hole communicating with the end, a screw inside the threaded hole, and a support plate fixed to the end of the screw.

[0008] A guide rod has a second transmission wheel fixed to its bottom side surface. A transmission belt is fitted onto the outer surface of the second transmission wheel. A rotating block is fixed to the top of the guide rod. A transmission rod is fixed to the upper surface of the rotating block near its end. A transmission ring is provided on the outer surface of the transmission rod. A push plate is fixed to the side surface of the transmission ring.

[0009] Preferably, the push plate is movably disposed on the upper surface of the cutting machine body, the upper surface of the cutting machine body is provided with a positioning groove, and a positioning block is fixed on the side surface of the end of the push plate. The positioning block corresponds to and is engaged with the positioning groove, forming a movable connection.

[0010] Preferably, a connecting block is fixed to the surface of the push plate, the end of the connecting block is fixed to the surface of the transmission ring, the outer side of the cutting machine body is provided with a first inner groove and a transmission rod, and the inner side of the cutting machine body is provided with a first inner groove and a second inner groove.

[0011] Preferably, the motor is fixed to the bottom surface of the inner wall of the second inner groove, the guide rod is movably disposed on the bottom surface of the inner wall of the first inner groove, and a bending block is fixed to the side surface of the inner wall of the second inner groove.

[0012] Preferably, the bending angle of the bending block is a right angle, and there are four groups of bending blocks, the dimensions of the four groups of bending blocks being the same as the dimensions of the support plate.

[0013] Preferably, a limiting groove is formed on the end side surface of the guide rod, and a connecting hole is formed on the inner wall surface of the first inner groove. The connecting hole is formed in two sets, upper and lower, with the upper set of connecting holes penetrating the inner wall of the first inner groove to communicate with the outside.

[0014] Preferably, a limiting block is fixed to the inner wall of the connecting hole, and the limiting block corresponds to and is engaged with the limiting groove, and the two are movably connected.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] When the starting motor drives the receiving tube to rotate, it causes the screw to move upward along its axis, aligning the lower surface of the top layer of items to be cut with the cutting table. Simultaneously, the rotation of the receiving tube drives the guide rod to rotate via the transmission belt. It takes multiple rotations of the receiving tube to drive the guide rod to rotate once. One rotation of the guide rod drives the rotating block and the transmission rod to rotate once. The transmission rod does not rotate on its own axis, but rather moves in a circle with the rotating block as its radius. During this circular motion, the transmission rod pushes the push plate towards the cutting table via the transmission ring. The push plate reaches its limit of movement when the transmission rod is closest to the cutting table. The moving push plate then pushes the top layer of items to be cut onto the cutting table for cutting. The same process is used to load the next layer of items, thus achieving automatic loading of the laser cutting machine, saving time and effort, and improving cutting efficiency.

[0024] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] Example 1, please refer to Figures 1-4 This utility model provides a technical solution: an automatic feeding mechanism for a precision laser cutting machine. A receiving tube 5 is fixed to the output end of a motor 7. A first transmission wheel 6 is fixed to the bottom side surface of the receiving tube 5. A transmission belt 15 is sleeved on the outer surface of the first transmission wheel 6. The transmission belt 15 provides power for the rotation of the guide rod 13. A threaded hole 17 is opened inside the receiving tube 5. The threaded hole 17 connects to the end. A screw 16 is provided inside the threaded hole 17. Since the threaded engagement with the support plate 4 is restricted by the bending block 18, when the motor 7 drives the receiving tube 5 to rotate, it will drive the screw 16 to move upward along its axis, making the lower surface of the uppermost item to be cut flush with the cutting table. A support plate 4 is fixed to the end of the screw 16.

[0026] A second transmission wheel 14 is fixed to the bottom side surface of the guide rod 13. Since the diameter of the first transmission wheel 6 is much smaller than the diameter of the second transmission wheel 14, the storage tube 5 needs to rotate many times to drive the guide rod 13 to rotate once. That is, when the support plate 4 drives the top item to be cut to be aligned with the cutting table, the guide rod 13 will rotate exactly once. A transmission belt 15 is sleeved on the outer surface of the second transmission wheel 14. A rotating block 10 is fixed to the top of the guide rod 13. A transmission rod 11 is fixed to the upper surface of the rotating block 10 near the end. A transmission ring 9 is provided on the outer surface of the transmission rod 11. A push plate 2 is fixed to the side surface of the transmission ring 9. The transmission rod 11 does not rotate on its own axis, but moves in a circle with the rotating block 10 as the radius. When the transmission rod 11 moves in a circle, it will push the push plate 2 to move towards the cutting table through the transmission ring 9. The push plate 2 is at its limit of movement when the transmission rod 11 is closest to the cutting table.

[0027] Based on Embodiment 1, in order to realize the automatic feeding function of the laser cutting machine body 1, the push plate 2 is movably set on the upper surface of the cutting machine body 1. The upper surface of the cutting machine body 1 is provided with a positioning groove 19, which plays a positioning role in the movement of the push plate 2 and prevents the push plate 2 from shifting when the transmission rod 11 rotates. A positioning block 3 is fixed on the end side surface of the push plate 2. The positioning block 3 corresponds to and is locked with the positioning groove 19, and is movably connected.

[0028] A connecting block 8 is fixed on the surface of the push plate 2. The end of the connecting block 8 is fixed to the surface of the transmission ring 9. The first inner groove 20 and the transmission rod 11 are located outside the cutting machine body 1. The first inner groove 20 and the second inner groove 23 are opened inside the cutting machine body 1.

[0029] The motor 7 is fixed to the bottom surface of the inner wall of the second inner groove 23, the guide rod 13 is movably set on the bottom surface of the inner wall of the first inner groove 20, and the bending block 18 is fixed on the side surface of the inner wall of the second inner groove 23. Due to the threaded fit and the fact that the support plate 4 is restricted by the bending block 18, the motor 7 drives the storage tube 5 to rotate, which will drive the screw 16 to move upward along its axis.

[0030] The bending angle of the bending block 18 is a right angle. There are four sets of bending blocks 18. The dimensions between the four sets of bending blocks 18 are the same as the dimensions of the support plate 4, which plays a limiting role on the support plate 4. When the support plate 4 is limited, the screw 16 will be limited, preventing the screw 16 from rotating when the storage tube 5 rotates.

[0031] A limiting groove 12 is provided on the end side surface of the guide rod 13, and a connecting hole 21 is provided on the inner wall surface of the first inner groove 20. The connecting hole 21 has two sets, upper and lower, with the upper set of connecting holes 21 penetrating the inner wall of the first inner groove 20 to connect to the outside.

[0032] A limiting block 22 is fixed to the inner wall of the connecting hole 21. The limiting block 22 corresponds to and is engaged with the limiting groove 12. The two are movably connected, so that the guide rod 13 is rotatably disposed in the first inner groove 20. The cooperation between the limiting block 22 and the limiting groove 12 prevents the guide rod 13 from shifting when rotating.

[0033] In actual use, a trolley is used to place multiple sets of items to be cut onto the support plate 4 in the second inner groove 23. Then, the motor 7 is started. Due to the threaded fit and the fact that the support plate 4 is restricted by the bending block 18, when the motor 7 drives the storage tube 5 to rotate, it will drive the screw 16 to move upward along its axis, making the lower surface of the top layer of items to be cut flush with the cutting table. At the same time, the rotation of the storage tube 5 will drive the guide rod 13 to rotate through the transmission belt 15. Since the diameter of the first transmission wheel 6 is much smaller than the diameter of the second transmission wheel 14, the storage tube 5 will rotate many times before driving the guide rod 13 to rotate one revolution. That is, when the support plate 4 moves the top layer of items to be cut to be flush with the cutting table, the guide rod 13 is... When the guide rod 13 rotates once, it will cause the rotating block 10 and the transmission rod 11 to rotate once. The transmission rod 11 does not rotate on its own axis, but moves in a circle with the rotating block 10 as the radius. When the transmission rod 11 moves in a circle, it will push the push plate 2 to move towards the cutting table through the transmission ring 9. When the transmission rod 11 is closest to the cutting table, it is the limit of the movement of the push plate 2. The lower surface of the push plate 2 is flush with the upper surface of the cutting table. Therefore, the moving push plate 2 will push the top layer of the support plate 4 to be cut into the cutting table for cutting. The same principle applies to the loading of the next layer of the item to be cut, thus realizing the automatic loading function of the laser cutting machine body 1, saving time and effort and improving cutting efficiency.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
