Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-4 , the present utility model provides the following technical solutions: A plant fixing device for a film laminating machine, including a film laminating machine frame 1, a mounting plate 2 is connected to one side surface of the film laminating machine frame 1, a vertical frame 3 is connected to the top surface of the mounting plate 2, an electric push rod 4 is connected to the top surface of the vertical frame 3, the movable end of the electric push rod 4 penetrates through the vertical frame 3 and is connected to a connecting block 5, one end of the connecting block 5 extends into the interior of a connecting groove 6, the connecting groove 6 is opened on the top surface of a convex block 7, bolts 8 penetrate through both side surfaces of the convex block 7, one end of the bolt 8 extends into a fixing hole 9 opened on one side surface of the connecting block 5, a connecting frame 10 is connected to the bottom surface of the convex block 7, a punching cylinder 11 is connected to the inner surface of the bottom end of the connecting frame 10, one end of the punching cylinder 11 penetrates through a through groove 12 opened on the bottom surface of the mounting plate 2, a PLC control switch 20 is connected to one end surface of the vertical frame 3, and an adjusting mechanism is further provided on one end surface of the mounting plate 2.

[0023] Preferably, the adjusting mechanism includes: a vertical block 13, a movable groove 14, a bearing 15, a screw rod 16, a motor 17, a movable block 18, and a roller rangefinder 19. One end surface of the mounting plate 2 is connected with the vertical block 13. One end surface of the vertical block 13 is provided with the movable groove 14. Both ends of the inner side of the movable groove 14 are connected with the bearing 15. A screw rod 16 is connected between the two bearings 15. One end of the screw rod 16 extends into the vertical block 13 and is connected with the output end of the motor 17. And a movable block 18 is connected through the screw rod 16 at one end. One side surface of the movable block 18 is connected with the roller rangefinder 19. The model of the roller rangefinder 19 is ARZ-LS digital display roller rangefinder.

[0024] During specific use, by starting the motor 17, the output end of the motor 17 drives the screw rod 16 to rotate in the bearing 15, so that the movable block 18 on the screw rod 16 will move along the movable groove 14 on the vertical block 13. In this way, the movable block 18 will drive the roller rangefinder 19 to move, so that the roller on the roller rangefinder 19 can be in good contact with the ground, enabling the roller rangefinder 19 to accurately measure the moving distance. In this way, when the film laminator operates, it will drive the roller on the roller rangefinder 19 to roll on the film, thereby measuring the moved distance.

[0025] Preferably, the electric push rod 4, the motor 17, and the roller rangefinder 19 are electrically connected to the power supply of the film laminator through a PLC control switch 20.

[0026] During specific use, the model of the PLC control switch 20 is S7-200 small PLC control switch. Through programming, the PLC control switch 20 can switch the connected devices. A Hall sensor is arranged on the stator of the motor inside the electric push rod 4. The signal output line of the Hall sensor is connected to the digital input interface of the PLC control switch 20. In this way, the movable end of the electric push rod 4 can move a fixed distance through setting. The PLC control switch 20 is also connected to the driver of the film laminator. In this way, the PLC control switch 20 can control the electric push rod 4, the motor 17, the roller rangefinder 19, and the film laminator through programming.

[0027] Preferably, the connecting block 5 and the convex block 7 form a sliding connection through the connecting groove 6, and the bolt 8 forms a threaded connection with the fixing hole 9 by passing through the convex block 7.

[0028] During specific use, the connecting block 5 can be slidably placed into the connecting groove 6, and then the bolt 8 is passed through the convex block 7 and screwed into the fixing hole 9, so that the position of the connecting block 5 can be fixed in the connecting groove 6, connecting the connecting block 5 and the convex block 7 together.

[0029] Preferably, a fixed connection is formed between the output end of the motor 17 and the screw rod 16.

[0030] During specific use, when the output end of the motor 17 rotates, it can drive the screw rod 16 to rotate in the bearing 15.

[0031] Preferably, a threaded connection is formed between the movable block 18 and the screw rod 16, and a sliding connection is formed between the movable block 18 and the vertical block 13 through the movable groove 14.

[0032] During specific use, when the screw rod 16 rotates, the movable block 18 on the screw rod 16 can move along the movable groove 14 on the vertical block 13.

[0033] Working principle of implementation: When using the plant-spacing fixer of this film mulching machine, it should be particularly noted here that the punching cylinder 11 can be customized with different sizes according to requirements. By programming the PLC control switch 20, when the film mulching machine performs the film mulching operation, first start the motor 17, and let the output end of the motor 17 drive the screw rod 16 to rotate in the bearing 15, which can make the movable block 18 on the screw rod 16 move along the movable groove 14 on the vertical block 13. In this way, the movable block 18 will drive the roller rangefinder 19 to move, so that the rollers on the roller rangefinder 19 can be in good contact with the ground, enabling the roller rangefinder 19 to accurately measure the moving distance. In this way, when the film mulching machine operates, it will drive the rollers on the roller rangefinder 19 to roll on the film mulch. When the measured moving distance reaches the set value after rolling, the PLC control switch 20 will turn off the driver of the film mulching machine, so that the film mulching machine will no longer move forward. At this time, the PLC control switch 20 will start the electric push rod 4, and let the movable end of the electric push rod 4 drive the punching cylinder 11 connected to the bottom connecting frame 10 of the convex block 7 connected by the connecting block 5 to penetrate through the through groove 12, so that the punching cylinder 11 can be inserted into the soil. Then, let the movable end of the electric push rod 4 drive the punching cylinder 11 to move upward, which can drive part of the soil to separate from the soil, so that the punching operation can be completed on the film-mulched soil. By performing subsequent punching operations in this way, the operator can perform the punching operation with a fixed plant spacing while using the film mulching machine to perform film mulching, avoiding the need for other personnel to perform the punching operation subsequently, thereby reducing the number of workers and lowering the labor cost.

[0034] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
