[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The utility model provides Figure 1-Figure 4The automatic feeding device for double-end milling of woodworking shown in the figure includes a base plate 1, and a transmission component is arranged on the top of the base plate 1, and the transmission component includes a first support plate 2 and a second support plate 3, and the first support plate 2 and the second support plate 3 are both fixedly installed on the base plate 1, and a transmission frame 4 is fixedly arranged on the surface of the first support plate 2 and the second support plate 3 close to each other, and two driving shafts are rotatably arranged in the transmission frame 4, and a transmission belt 5 is rotatably arranged on the two driving shafts. After the woodworking element is placed on the transmission belt 5, the driving shaft is started to drive the transmission belt 5 to rotate, and the woodworking element is transmitted. An anti-slip strip is arranged at the outer ring of the transmission belt 5 to increase the friction between the woodworking element and the transmission belt 5, so that the woodworking element is better transmitted.

[0025] In order to realize automatic feeding of the device, a feeding assembly is arranged on the transmission assembly, and the feeding assembly includes a gantry 6, and two gantry frames 6 are arranged. One end of the gantry 6 is fixedly mounted on the top of the first support plate 2, and the other end of the gantry 6 is fixedly mounted on the top of the bottom plate 1. A T-shaped movable groove is arranged on the gantry 6, and a movable plate 9 is slidably arranged in the T-shaped movable groove. The movable plate 9 is adapted to the T-shaped movable groove. A hydraulic rod 7 is arranged at the end of the gantry 6, and a telescopic rod 8 is movably arranged at the end of the hydraulic rod 7. One end of the telescopic rod 8 that movably extends into the T-shaped movable groove is fixedly connected to the movable plate 9. A first electric push rod 10 is arranged in the movable plate 9, and a lifting plate 11 is fixedly arranged on the telescopic end of the first electric push rod 10. Two suction cups 12 are arranged at the bottom of the lifting plate 11. The suction cup 12 is connected to the vacuum machine 15 through the air pipe 13. The vacuum machine 15 is fixedly mounted on the top of the support seat 14, and the support seat 14 is fixedly mounted between the two gantries 6;

[0026] Specifically, the raw materials are stacked on one side of the second support plate 3, the hydraulic rod 7 is started, and the telescopic rod 8 pushes the movable plate 9 to move in the T-shaped movable groove. When the movable plate 9 moves to the top of the raw materials, the hydraulic rod 7 is paused, and the vacuum machine 15 is started to allow the two suction cups 12 to suck the woodworking elements above the raw material pile, and the hydraulic rod 7 is started in the reverse direction to allow the telescopic rod 8 to push the movable plate 9 to move in the T-shaped movable groove to the middle position of the first support plate 2 and the second support plate 3, the hydraulic rod 7 is paused, and the first electric push rod 10 is started to drive the lifting plate 11, the suction cup 12 and the woodworking elements to move. After the woodworking component is placed on the conveyor belt 5, the vacuum machine 15 is paused to release the woodworking component and allow the conveyor belt 5 to transport it, thereby avoiding the disadvantages of manual feeding, improving work efficiency, enhancing the accuracy of feeding, ensuring the processing accuracy of woodworking components, and ensuring the processing quality of products. In addition, by sucking the woodworking component by the suction cup 12, woodworking components of different thicknesses can be grabbed and fed, solving the problem that the automatic feeding device of the existing woodworking double-end milling cannot continuously feed woodworking components of different thicknesses, limiting the applicability of the device.

[0027] In order to ensure stable transmission of woodworking components on the conveyor belt 5 and avoid jitter and displacement, a connecting plate 27 is fixedly provided at the bottom of the movable plate 9, and the connecting plate 27 and the lifting plate 11 are arranged perpendicular to each other. The telescopic end of the first electric push rod 10 is slidably connected to the connecting plate 27, and the second electric push rods 16 are arranged at both ends of the connecting plate 27. The telescopic end of the second electric push rod 16 can move through the two side surfaces of the connecting plate 27, and a pulley 17 is rotatably provided at one end passing through the two side surfaces of the connecting plate 27. When the suction cup 12 releases the woodworking component, the second electric push rod 16 is started to move the pulley 17 downward to press the woodworking component, thereby avoiding jitter and displacement of the woodworking component during transmission and improving the transmission stability of the woodworking component. The height of the pulley 17 is adjustable, so that woodworking components of different thicknesses can be compressed and transmitted, thereby improving the applicable surface of the device.

[0028] After the woodworking element is conveyed, the movable plate 9 moves to the initial position to prepare for grabbing and loading the next woodworking element.

[0029] Furthermore, in the initial state, the upper surface of the lifting plate 11 and the lower surface of the connecting plate 27 are movably fitted together, so that the connecting plate 27 does not affect the up and down displacement of the lifting plate 11, and when the suction cup 12 sucks the woodworking element, the pulley 17 does not touch the woodworking element.

[0030] In order to reduce the extension length of the telescopic end of the first electric push rod 10 and allow the suction cup 12 to quickly suck the woodworking element, thereby shortening the loading time of the device, a lifting component is arranged on the top of the base plate 1, and the lifting component includes a fixed plate 18, the fixed plate 18 is fixedly installed on the top of the base plate 1, a slide groove is arranged in the fixed plate 18, a motor 19 is fixedly arranged at the end of the slide groove, a bidirectional screw rod 20 is fixedly connected to the rotating shaft of the motor 19, two first connecting bases 21 are rotatably arranged at the outer ring of the bidirectional screw rod 20, a material discharge platform 24 is slidably arranged between the gantry 6 and the second support plate 3, and two second connecting bases 23 are fixedly arranged at the bottom of the material discharge platform 24, and the second connecting base 23 is rotatably connected to the first connecting base 21 through a steering rod 22;

[0031] Specifically, the woodworking components are stacked on the discharge table 24. When the suction cup 12 is located between the first support plate 2 and the second support plate 3, the motor 19 is started to drive the bidirectional screw rod 20 to rotate, so that the two first connecting bases 21 are relatively displaced, and the discharge table 24 is driven to move upward by a unit length. When the suction cup 12 moves to the top of the discharge table 24, it can touch the woodworking components, allowing the suction cup 12 to quickly absorb the woodworking components, thereby shortening the loading time of the device and improving the processing efficiency of the device.

[0032] In order to improve the stability of the displacement of the unloading platform 24, four limit blocks 25 are fixedly arranged at the end of the unloading platform 24, and the gantry 6 and the second support plate 3 are provided with limit grooves 26 adapted to the limit blocks 25. The limit grooves 26 are used to limit the up and down displacement trajectory of the unloading platform 24, thereby improving the stability of the up and down displacement of the unloading platform 24.
