Detailed Implementation

[0020] The present invention will be further described below with reference to embodiments, but this does not constitute any limitation on the present invention. Any limited modifications made by any person within the scope of the claims of the present invention are still within the scope of the claims of the present invention.

[0021] See Figures 1-2 This utility model discloses a standardized rapid line marking device for workshops. The device includes a support frame, which includes a fixed plate 8, a second side plate 16, and two first side plates 11. The two first side plates 11 are respectively installed on both sides of the second side plate 16. One side of the fixed plate 8 is fixedly installed on the second side plate 16. A tape rolling structure is installed between the two first side plates 11. Roller structures are provided on both sides of the fixed plate 8. A support rod 2 and a deviation alarm module are provided above the fixed plate 8. The deviation alarm module is provided with a receiving end for receiving laser emitted by a laser transmitter 1. A paint spraying structure is installed on the support rod 2.

[0022] The tape rolling structure includes a first mounting shaft 15, a second roller 13, a first cylinder 9, and a second cylinder 10. The first mounting shaft is mounted between two first side plates 11 via second bolts 12 at both ends. The first cylinder 9 and the second cylinder 10 are rotatably mounted on the first mounting shaft 15, and tape is placed on both cylinders 9 and 10. A first limiting block 21 and a second limiting block 22 are fixedly mounted on the first mounting shaft 15. The second roller 13 is rotatably mounted between the two first side plates 11 via third bolts 14, and is drivenly connected to both cylinders 9 and 10. When the second roller 13 rotates, it drives the first cylinders 9 and 10 to rotate, thereby adhering the tape on the first cylinders 9 and 10 to form a standardized painting area, achieving rapid line drawing.

[0023] The second roller 13 has a relief groove 23 in the middle. By setting the relief groove 23, the diameter of the middle part of the second roller 13 is smaller than the diameter of the two sides. When spraying paint, the middle part of the second roller 13 does not come into contact with the ground, thereby avoiding contact between the middle part of the second roller 13 and the sprayed paint, and avoiding affecting the clarity of the paint on the ground.

[0024] The roller structure includes a second mounting shaft and two first rollers 6. The fixing plate 8 is provided with a through hole, through which the second mounting shaft is inserted. The first rollers 6 are rotatably mounted on the second mounting shaft by a first bolt 7.

[0025] The paint spraying structure includes a paint box 18 and a nozzle 17. The paint box 18 is fixedly mounted on the support rod 2, and the nozzle 17 is fixedly mounted on the paint box 18 and communicates with the paint box 18. The nozzle 17 is equipped with a circular knob and faces between the first cylinder 9 and the second cylinder 10. The paint spraying structure allows the actions of applying adhesive tape and spraying paint to be performed simultaneously, thereby improving work efficiency.

[0026] A handle 3 is fixedly installed at the end of the support rod 2 away from the fixed plate 8. The handle 3 is provided for easy pushing. The fixed plate 8, the second side plate 16, and the two first side plates 11 are an integral structure.

[0027] A first limiting block 21 and a second limiting block 22 are fixedly installed in the middle of the first mounting shaft 15. The first limiting block 21 is used to limit the lateral movement of the first cylinder 9, and the second limiting block 22 is used to limit the lateral movement of the second cylinder 10.

[0028] The deviation alarm module includes a laser emitter 1, a controller 20, an alarm 19, and a laser receiver 4. The laser emitter 1 is placed in a predetermined position. A guide pin 5, the alarm 19, and the laser receiver 4 are fixedly installed on the side of the mounting plate 8 away from the second side plate 16. The controller 20 is installed on the second side plate 16, and both the alarm 19 and the laser receiver 4 are electrically connected to the controller 20. The guide pin 5 is used to align the laser emitted by the laser emitter. The deviation alarm module helps to alert workers when the rapid line drawing device deviates from the optical path, preventing unsightly and irregular lines from being drawn, and also improving work efficiency.

[0029] The working principle of this utility model is as follows: The laser emitter 1 is placed at the predetermined position for marking the line. The tape ends of the first cylinder 9 and the second cylinder 10 are both placed on the ground, with both tape ends located below the second roller 13. The laser emitter 1 is then turned on to emit a visible laser. The guide needle 5 is aligned with the visible laser. By pushing the handle 3, the second roller 13 and the first roller 6 are rotated, thereby moving the rapid line-marking device. Simultaneously, the rapid line-marking device is moved, positioning the guide needle 5 within the optical path of the visible laser.

[0030] During the operation of the rapid line drawing device, the second roller 13 drives the first cylinder 9 and the second cylinder 10 to rotate. The tape on the first cylinder 9 and the second cylinder 10 continuously adheres to the designated area along the travel path of the second roller 13, and the rolling second roller 13 makes the tape adhere more firmly to the designated area. By rotating the circular knob on the nozzle 17, the paint in the paint box 18 is controlled to fall between the first cylinder 9 and the second cylinder 10, so that the tape on the first cylinder 9 and the tape on the second cylinder 10 are fully sprayed with paint. After the paint dries, the tape is torn off to form a standardized straight line.

[0031] Laser receiver 4 receives the laser emitted by laser transmitter 1 and inputs a receiving signal to controller 20. When the rapid line drawing device deviates from the laser beam path, laser receiver 4 does not input a receiving signal to controller 20. Controller 20 then controls alarm 19 to sound an alarm, thereby reminding staff to correct the pushing direction.

[0032] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present utility model. These modifications and improvements will not affect the effectiveness of the present utility model or the practicality of the patent.
