When the translation frame 7 moves forward, it can synchronously drive the material moving platform 8 to move forward from the material picking station to the stacking station; when the translation frame 7 moves backward, it can synchronously drive the material moving platform 8 to reset backward from the stacking station to the material picking station; a swing driving mechanism is provided between the driving end of the swinging frame 4 and the bracket 3 to drive the swinging frame 4 to rotate upward or downward. After the material moving platform 8 is located at the material picking station, when the swinging frame 4 rotates upward, it can synchronously drive the material moving platform 8 to lift up to hold up the profile located at the material picking station on the chain conveying platform 1; after the material moving platform 8 is located at the stacking station, when the swinging frame 4 rotates downward, the lifted profile can be placed on the stacking platform of the stacking station;

[0019] In this embodiment, the structure of the translation drive mechanism includes: a rack 10 running forward and backward is installed at the bottom of the translation frame 7, a translation motor 11 is installed in the swing frame 4, and a gear 12 meshing with the rack 10 is installed on the output shaft of the translation motor 11. The translation motor 11 cooperates with the rack 10 through the gear 12 to synchronously drive the translation frame 7 to move forward or backward relative to the swing frame 4. The above-mentioned translation drive mechanism has a simple structure and is easy to install and maintain;

[0020] In this embodiment, the structure of the swing drive mechanism includes: a supporting wheel 13 is supported at the bottom of the driving end of the swing frame 4, a swing motor 14 is installed on the bracket 3, and an eccentric cam 15 corresponding to the supporting wheel 13 is mounted on the output shaft of the swing motor 14.

The swing motor 14 drives the eccentric cam 15 to rotate to drive the swing frame 4 to rotate upward or downward. The above-mentioned swing drive mechanism has a simple structure and is easy to install and maintain;

[0021] In this embodiment, the material transfer platform 8 is composed of a plurality of javelin-type material transfer rods arranged side by side with the tip facing forward, so that when the material transfer platform 8 moves the profile to the stacking platform of the stacking station, the drop of the profile from the material transfer platform 8 to the stacking platform can be reduced during the process of the material transfer platform 8 withdrawing the profile, thereby avoiding the occurrence of the profile being scattered due to the large drop, and improving the stability of the equipment.

[0022] In this embodiment, a profile pressing mechanism is also provided at the stacking station, and the structure of the profile pressing mechanism includes: a pressing frame 16, a pressing plate 17 is provided on the pressing frame 16, the middle part of the pressing plate 17 is hinged to the upper part of the pressing frame 16 through a pin 18, a pressing hydraulic cylinder 19 is provided on the pressing frame 16, the cylinder body of the pressing hydraulic cylinder 19 is hinged to the pressing frame 16, and the piston rod of the pressing hydraulic cylinder 19 is connected to the lower end of the pressing plate 17. The hinged structure is such that when the piston rod of the material pressing hydraulic cylinder 19 is extended, the material pressing plate 17 can be driven to rotate downward around the pin 18 to press downward the profile that is moved to the stacking station with the material moving platform 8. When the piston rod of the material pressing hydraulic cylinder 19 is retracted, the material pressing plate 17 can be driven to rotate upward around the pin 18 to leave the profile located at the stacking station. The material pressing mechanism is used in conjunction with the material moving platform 8 when the material moving platform is to be withdrawn from the profile. Before the platform is ready to withdraw the profile, the piston rod of the pressure hydraulic cylinder 19 of the profile pressing mechanism extends out, driving the pressure plate 17 to rotate downward around the pin shaft 18 until the pressure plate 17 presses the profile on the material moving platform 8 downward. While keeping the pressure plate 17 pressing the profile, the material moving platform 8 is pulled away from the profile, thereby preventing the profile from being scattered during the withdrawal of the material moving platform 8, further improving the stability of the equipment. In this embodiment, a limit plate 20 is fixed on the pressure frame 16, and an arc-shaped limit hole 21 concentric with the pin shaft 18 is provided on the limit plate 20. A guide shaft 22 that extends into and can move along the arc-shaped limit hole 21 is installed at the lower end of the pressure plate 17. In the process of the pressure plate 17 pressing the profile, the pressure plate 17 is limited to the upward and downward positions of the pressure plate 17 through the limiting cooperation of the guide shaft and the arc-shaped limit hole 21, so as to avoid excessive downward pressure of the pressure plate 17 on the profile.

[0023] The working principle of the utility model is as follows:

[0024] The chain conveyor platform 2 conveys the profile forward, and the profile will be blocked by the block 2 and collected at the material-retrieving station; then the swing motor 14 drives the eccentric cam 15 to rotate to drive the swing frame 4 to rotate upward, and simultaneously drives the translation frame 7 and the material-transferring platform 8 to rotate upward, so that the material-transferring platform 8 is lifted up to hold up the profile located at the material-retrieving station on the chain conveyor platform 1;

[0025] Then, the translation motor 11 cooperates with the rack 10 through the gear 12 to synchronously drive the translation frame 7 to move forward relative to the swing frame 4, and synchronously drives the material transfer platform 8 to move forward from the material taking station to the stacking station;

[0026] Then, the swing motor 14 drives the eccentric cam 15 to continue to rotate to drive the swing frame 4 to rotate downward, and synchronously drives the translation frame 7 and the material transfer platform 8 to rotate downward, so that the material transfer platform 8 places the lifted profile on the stacking platform of the stacking station; before the material transfer platform 8 is ready to move backward to extract the profile, the piston rod of the material pressing hydraulic cylinder 19 of the profile pressing mechanism extends, driving the material pressing plate 17 to rotate downward around the pin 18 until the material pressing plate 17 presses the profile on the material transfer platform 8 downward, and keeps the material pressing plate 1 When the profile is pressed against the profile, the translation motor 11 cooperates with the rack 10 through the gear 12 to synchronously drive the translation frame 7 to move backward relative to the swing frame 4, and synchronously drives the material transfer platform 8 to move backward from the stacking station to the material taking station, so that the material transfer platform 8 is pulled away from the profile; after the material transfer platform 8 is pulled away from the profile, the piston rod of the material pressing hydraulic cylinder 19 is retracted, driving the material pressing plate 17 to rotate upward around the pin 18 to leave the profile at the stacking station; thereby completing the stacking of one layer of profiles on the stacking platform;

[0027] Repeat the above steps until the specified number of layers of profiles are stacked.

[0028] The utility model has the advantages of being able to automatically complete the stacking of profiles, having low labor intensity for workers, high work efficiency and high safety in use.
