Description

Technical Field

[0001] The utility model relates to the technical field of ground leveling equipment, in particular to an automatic film covering mechanism. Background Technique

[0002] For ground leveling treatment, eliminate the undulation and unevenness of the ground, make the ground reach a certain level of flatness and smoothness, and cover a layer of film on the leveled ground. This layer of film has various functions, such as preventing water evaporation, maintaining soil humidity, inhibiting weed growth, raising soil temperature, etc.;

[0003] During the process of film covering work, at the starting point, one end of the film is fixed on the ground, and then two operators hold and gradually unfold the film along the direction of the ground. During the unfolding process, it is necessary to ensure that the film is tightened and laid flat to avoid wrinkles or bubbles. When the film is unfolded to the other end of the ground, the other end of the film is also fixed on the ground. At the same time, the two side edges of the film also need to be fixed with soil or other materials to ensure that the film will not move or be blown up;

[0004] Currently, during the process of film covering work, although manual film covering can be carried out, manual film covering not only damages the already leveled working surface, but also requires two people to work simultaneously. The entire construction process is time-consuming and laborious, with high construction costs and low work efficiency. For this reason, we propose an automatic film covering mechanism.

The lower end of the telescopic end of the electric push rod 2 is fixedly connected to the upper end of the tool rest 4. The input end of the electric push rod 2 is electrically connected to the output end of an external robot controller. The telescopic end of the electric push rod 2 extends, thereby driving the tool rest 4 to move downward. Then, the film 10 is pressed and fixed by a pressing device. At this time, the telescopic end of the electric push rod 2 continues to extend, and finally the lower end of the cutting knife 8 contacts the upper surface of the film 10, so as to cut the film 10 by the cutting knife 8.

[0022] Among them: It also includes a pressing assembly 5. The pressing assembly 5 includes a mounting plate 51, sliding columns 52, polyurethane pressing strips 53 and baffles 54.

The upper ends of the sliding columns 52 are all provided with baffles 54. One polyurethane pressing strip 53 is arranged at the lower ends of two laterally adjacent sliding columns 52. The pressing assembly 5 also includes springs 55. The springs 55 are respectively arranged between the lower ends of the baffles 54 and the upper ends of the mounting plates 51. The springs 55 are all sleeved on the outer side of the upper side of the sliding columns 52. When the polyurethane pressing strip 53 contacts the upper surface of the film 10, the polyurethane pressing strip 53 fixes the film 10 on the front side of the upper end of the shearing platform 9.

[0023] Among them: It also includes a fixing frame 12 and a top plate 14. The fixing frames 12 are all arranged on the rear side of the top wall of the mounting frame 11. The top plates 14 are all slidably connected to the top walls of the fixing frames 12. During the rotation of the adjusting device, the top plates 14 are driven to move forward through threaded connection, and finally the front ends of the top plates 14 contact the rear surface of the leveling mechanism, thereby realizing the installation and fixation of the automatic film laminating mechanism.

[0024] Among them: It also includes a screw rod 13. The screw rods 13 are all rotatably connected to the middle of the rear end of the fixing frame 12 through bearings. The front ends of the screw rods 13 are all rotatably connected to the connection grooves arranged in the middle of the rear end of the top plate 14 through bearings. Before use, the automatic film laminating mechanism is moved to a designated working location, and the fixing frame 12 is placed on the upper side of the corresponding leveling mechanism. Then, the adjusting device is rotated. The adjusting device drives the screw rod 13 to rotate. During the rotation of the screw rod 13, the top plate 14 is driven to move forward through threaded connection, and finally the front end of the top plate 14 contacts the rear surface of the leveling mechanism, thereby realizing the installation and fixation of the automatic film laminating mechanism.

[0025] Among them: It further includes an adjusting runner 15. The adjusting runners 15 are all arranged at the rear end of the screw rod 13. Before use, move the automatic film covering mechanism to the designated working location, place the fixing frame 12 on the upper side of the corresponding leveling mechanism, and then rotate the adjusting runner 15. The adjusting runner 15 drives the screw rod 13 to rotate. During the rotation of the screw rod 13, it drives the top plate 14 to move forward through threaded connection. Finally, the front end of the top plate 14 contacts the rear surface of the leveling mechanism, thereby realizing the installation and fixation of the automatic film covering mechanism.

[0026] The working principle of an automatic film covering mechanism provided by the present utility model is as follows: Before use, move the automatic film covering mechanism to the designated working location, place the fixing frame 12 on the upper side of the corresponding leveling mechanism, and then rotate the adjusting runner 15. The adjusting runner 15 drives the screw rod 13 to rotate. During the rotation of the screw rod 13, it drives the top plate 14 to move forward through threaded connection. Finally, the front end of the top plate 14 contacts the rear surface of the leveling mechanism, thereby realizing the installation and fixation of the automatic film covering mechanism. Then, spread out the film 10. During the spreading process, the film 10 passes through the front side of the upper end of the cutting platform 9. Finally, the lower end of the film 10 contacts the upper surface of the wet concrete ground. During the process that the automatic film covering ground leveling robot drives the film 10 to move through the leveling mechanism, the adsorption force of the wet concrete ground spreads the film 10 evenly on the leveled finished surface along with the moving speed of the automatic film covering ground leveling robot. When the automatic film covering ground leveling robot levels to the end point position according to the planned path, the electric push rod 2 receives a specific instruction from the robot controller, and the electric push rod 2 starts to operate. The telescopic end of the electric push rod 2 extends, thereby driving the tool rest 4 to move downward. When the polyurethane pressing strip 53 contacts the upper surface of the film 10, the polyurethane pressing strip 53 fixes the film 10 on the front side of the upper end of the cutting platform 9. At this time, the telescopic end of the electric push rod 2 continues to extend, and the spring 55 contracts. Finally, the lower end of the cutting knife 8 contacts the upper surface of the film 10, thereby cutting the film 10 through the cutting knife 8. After the cutting is completed, the electric push rod 2 receives a specific instruction from the robot controller, and the telescopic end of the electric push rod 2 contracts. The thrust generated by the extension of the spring 55 can drive the polyurethane pressing strip 53 to move back through the baffle 54. Finally, drive the cutting knife 8 to move back through the tool rest 4.

[0027] It should be noted that the electric push rod 2 disclosed in the above embodiments can be selected as YRJ0905, and a control button corresponding to the electric push rod 2 for controlling its switch is arranged on the external robot controller.
