Description

Technical Field

[0001] This application relates to the field of line drawers, and more particularly to a line drawer. Background Technology

[0002] Sports fields, including those for various ball games, require lines to define their boundaries. Currently, common methods include applying tape or painting. However, before painting, double strips of release tape must be applied to prevent uneven lines. Therefore, regardless of the method, applying tape is essential. The commonly used manual tape application method is not only slow but also prone to errors, resulting in uneven tape application. Utility Model Content

[0003] To achieve straighter and more precise tape application, this application provides a line marker.

[0004] The line drawing device provided in this application adopts the following technical solution: A line marking device includes a line marking base, a line marking roller, and a pressure roller. The line marking roller is rotatably mounted on the line marking base, and tape is wound around the line marking roller. The pressure roller is rotatably mounted on the line marking base.

[0005] By adopting the above technical solution, when the sports field needs to be marked with isolation tape, the tape is wound onto the marking roller, and then one end of the tape is pasted to the ground so that the outer circumference of the pressing roller is pressed against one side of the tape. Then, the marking seat is pushed in the specified direction. As the marking seat moves continuously, the pressing roller rotates with the movement of the marking seat, so that the tape is gradually and accurately pasted to the required position, thus completing the tape pasting. This improves the commonly used method of manually applying tape, which is not only slow but also prone to uneven application due to improper operation.

[0006] Optionally, a drawing groove is provided on one side of the drawing base, and the drawing roller passes through the drawing groove so that the drawing roller is rotatably mounted on the drawing base.

[0007] Optionally, the line drawing base is rotatably connected to two line drawing wheels. When the line drawing base moves, the two line drawing wheels are pressed against the ground to make the line drawing base move smoothly.

[0008] Optionally, the marking base is connected to a push handle to facilitate the pushing of the marking base.

[0009] Optionally, the line drawing base includes a base body and a connecting part. The connecting part is fixedly disposed on the base body and has a connecting groove. When the push handle is connected to the line drawing base, the push handle passes through the connecting groove so that the push handle is connected to the line drawing base.

[0010] Optionally, a support rod is provided between the seat and the connecting part, one end of the support rod is fixedly connected to the connecting part, and the other end of the support rod is fixedly connected to the seat.

[0011] In summary, this application includes at least one of the following beneficial technical effects: When marking lines and applying isolation tape to a sports field, the tape is wound onto a marking roller, one end of the tape is then attached to the ground, and the outer circumference of the pressure roller is pressed against one side of the tape. The marking base is then pushed in the designated direction. As the marking base moves, the pressure roller rotates accordingly, allowing the tape to be applied evenly and precisely to the desired location. This method improves upon the commonly used manual tape application method, which is not only slow but also prone to uneven application due to improper operation. Attached Figure Description

[0014] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0015] This application discloses a line drawer and a line drawing method. (Refer to...) Figure 1 A line drawing device includes a line drawing base 1, a line drawing roller 2, a pressure roller 3, two line drawing wheels 4, and a push handle 5.

[0016] Reference Figure 1, Figure 2 as well as Figure 3 The line drawing base 1 includes a base part 11 and a connecting part 12. The connecting part 12 is cylindrical and is fixedly disposed on the base part 11. The connecting part 12 is inclined from one end of the base part 11 toward the other end of the base part 11 from top to bottom. A connecting groove 121 is provided at the end of the connecting part 12 away from the base part 11. A support rod 13 is disposed between the base part 11 and the connecting part 12. One end of the support rod 13 is fixedly connected to the connecting part 12, and the other end of the support rod 13 is fixedly connected to the base part 11. A push handle 5 is connected to the base part 11. When the push handle 5 is connected to the line drawing base 1, the push handle 5 passes through the connecting groove 121 so that the push handle 5 is connected to the line drawing base 1.

[0017] Reference Figure 1 , Figure 2 as well as Figure 3 A line-drawing groove 111 is provided on one side of the base 11. The groove 111 is inclined from the end near the connecting part 12 to the end away from the connecting part 12. The line-drawing roller 2 passes through the line-drawing groove 111 so that the line-drawing roller 2 is rotatably mounted on the line-drawing base 1. The tape is wrapped around the line-drawing roller 2. The pressure roller 3 is rotatably mounted on the base 11. Both ends of the pressure roller 3 are threaded with pressure nuts. The two pressure nuts are respectively pressed against both sides of the base 11 to make the rotational connection between the pressure roller 3 and the base 11 more stable. The line-drawing base 1 is rotatably connected to two line-drawing wheels 4. When the line-drawing base 1 moves, the two line-drawing wheels 4 are pressed against the ground to make the line-drawing base 1 move smoothly.

[0018] Reference Figure 1 , Figure 2 as well as Figure 3 The base 11 is fixedly equipped with two laser correctors 6. The laser correctors 6 can emit directional lasers. One laser corrector 6 can emit a laser pointing in the direction of movement of the line marker 10, which is called the X laser corrector 6. The other laser corrector 6 can emit a laser perpendicular to the direction of movement of the line marker 10, which is called the Y laser corrector 6. The base 11 is also fixedly equipped with an offset prompt module 7. When the direction of movement of the line marker 10 deviates, the offset prompt module 7 can issue a voice prompt, so that when the line marker 1 moves, the direction of movement of the line marker 1 can be adjusted in time according to the laser line emitted by the laser correctors 6, so that the movement path of the line marker 1 is straighter, and the tape is more evenly pasted on the ground 30, so that the tape is pasted more evenly and accurately. The push handle 5 is fixedly equipped with a meter counter 8, which is used to record the distance moved by the line marker 10.

[0019] like Figure 6As shown, a laser pointer 20 projects a pre-drawn line path onto the ground 30. The laser pointer 20 can be mounted on the line drawer 10 or set up independently to ensure the path is clearly visible. Next, a line drawing carrier, such as tape or inkjet tape, is mounted on the line drawing roller 2, and the line drawer 10 is pushed along the pre-drawn line path. During the pushing process, the pressure roller 3 ensures full contact between the carrier and the ground, and the line drawing wheel 4 ensures smooth movement of the equipment.

[0020] In the process of promoting, such as Figure 4 As shown, the laser corrector 6 continuously emits a laser, allowing the operator to adjust the pushing direction according to the laser line to avoid deviation. If a deviation occurs, the deviation warning module 7 will issue a warning. When the line marker 10 moves to the end of the path or the designated position, it stops pushing and performs the carrier cutting process. If tape is used, cutting can be done manually or using the cutter provided with the equipment; if it is an inkjet carrier, inkjet printing will automatically stop.

[0021] like Figure 5 As shown, after drawing the lines, you can check the straightness and adhesion of the lines, and make local repairs if necessary.

[0022] Regarding the carrier types, the line drawing method of this application supports multiple line drawing carriers: Adhesive tape carrier: suitable for temporary markings, such as sports field boundaries; Inkjet carrier: Suitable for permanent markings, such as road markings and parking lot signs. The line marker 10 can be fitted with a line-marking roller 2 or an inkjet module depending on the carrier type.

[0023] The base 11 can be fitted with an inkjet module, including an ink tank, printhead, and control system. The line-drawing roller 2 can be replaced with an inkjet roller, and the pressure roller 3 ensures that the ink is evenly applied to the ground. During the pushing process, the inkjet module automatically controls the ink volume according to the moving speed to achieve precise line drawing.

[0024] Inkjet carriers are suitable for permanent markings such as road markings or parking lot signs, and can achieve multi-color drawing by using different colored inks, thus expanding application scenarios.

[0025] The base 11 can also integrate an electric cutter module. The cutter is controlled by a microcontroller, and automatically triggers the cutting action when the meter counter 8 detects that the line marker has moved to the designated position. For tape carriers, the cutter can quickly cut; for inkjet carriers, the system can automatically stop inkjet printing and collect excess material.

[0026] It improves the accuracy and efficiency of line drawing, and is especially suitable for long-distance or repetitive tasks.

[0027] The laser corrector 6 supports both visible light and infrared laser modes, allowing users to select the appropriate mode based on the environment. Furthermore, the system can integrate a GPS module for synchronization with the laser, enabling large-scale outdoor line marking, and provides vibration or audible alarms via the offset indicator module 7.

[0028] Enhance the adaptability of the line marker in changing environments, improve calibration accuracy, and reduce human error.

[0029] The connecting part 12 can be equipped with a motor and battery pack, allowing the line marker to move via wireless remote control or a preset program. The push handle 5 can be converted into a control lever, and the meter counter 8 is linked to the motor to automatically adjust the speed.

[0030] It reduces operational intensity, improves line marking consistency and efficiency, and is suitable for large venues or commercial applications.

[0031] The implementation principle of the line marking device in this application embodiment is as follows: When the sports field needs to be marked with isolation tape, the tape is wound onto the line marking roller 2, and then one end of the tape is pasted to the ground so that the outer circumference of the pressure roller 3 is pressed against one side of the tape. Then, the line marking seat 1 is pushed along the specified direction. As the line marking seat 1 moves continuously, the pressure roller 3 rotates with the movement of the line marking seat 1, so that the tape is gradually and accurately pasted to the position that needs to be pasted, thereby completing the pasting of the tape. This improves the commonly used method of manually pasting tape, which is not only slow in work efficiency, but also prone to uneven pasting due to improper operation.

[0032] See Figure 7 This application also provides a line drawing method for a line drawer, including the following steps: Step 1: Project the pre-drawn line path onto the ground using the laser pointer; Step 2: Mount the line marking carrier onto the line marking roller; Step 3: Place the line marker at the starting point of the pre-drawn line path, and press the pressure roller against the carrier; Step 4: Push the line drawer along the pre-drawn line path; Step 5: The meter counter records the distance traveled for positioning purposes; Step 6: Stop pushing the line marker when it reaches the designated position; Step 7: Cut the drawing carrier; Step 8: Check the quality of the drawn lines and make local repairs if necessary.

[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
