[0040] A plurality of scribe device bodies 3 are distributed and connected to rack 1 along X direction;The scribe device body 3 includes turnover support 31, linear motion module 32, pigment box mounting seat 33 and pigment box body 34;

[0041] The turnover support 31 includes first side support seat 311, second side support seat 312, telescopic rod 313 and turnover cross frame 314;

[0042] The first side support seat 311 is fixedly connected to rack 1, and the second side support seat 312 is fixedly connected to rack 1, and the first side support seat 311 and the second side support seat 312 are respectively located on both sides of the roll conveyor 2;

[0043] The linear motion module 32 is connected to the turnover cross frame 314;

[0044] One side of the turnover cross frame 314 is pivoted to the first side support seat 311 through the first pivot shaft 315, and the axis direction of the first pivot shaft 315 is X direction;

[0045] One end of the telescopic rod 313 is pivoted to the first side support seat 311, and the other end is pivoted to the turnover cross frame 314;

[0046] The other side of the turnover cross frame 314 is detachably connected to the second side support seat 312;

[0047] The pigment box mounting seat 33 is connected to the linear motion module 32;

[0048] The paint box body 34 is connected to the paint box mounting seat 33.

[0049] In the above embodiment, a PLC is further included, and the PLC is electrically connected with the telescopic rod 313 and the linear movement module 32 respectively. Preferably, the Y-direction position of the paint box mounting seat 33 in each marking device body 3 can be preset in the PLC according to the marking requirements of different tires, and the linear movement module 32 of each marking device body 3 is controlled by the PLC to drive the movement of each paint box mounting seat 33 to the preset position, so as to realize the switching of multiple marking positions of different tire patterns, and automatically control the distance of different color lines as needed. When the maintenance of the roller conveyor belt 2 is needed, only the connection between the turnover cross frame 314 and the second side support seat 312 needs to be loosened, the telescopic rod 313 is controlled to be elongated, the turnover cross frame 314 is rotated along the first pivot shaft 315, and the turnover cross frame 314 is kept at an angle under the action of the telescopic rod 313, so that the roller conveyor belt 2 is kept at an angle, and the maintenance of the roller conveyor belt 2 is facilitated. Figure 3 Therefore, great convenience is brought to the operation of the equipment and the maintenance of the equipment.

[0050] As an optional embodiment, the linear movement module 32 includes a linear guide rail, a driving motor 321 and a synchronous belt 322. The synchronous belt 322 is connected to the turnover cross frame 314, the driving motor 321 is connected to the turnover cross frame 314, the driving motor 321 is in transmission connection with the synchronous belt 322, the paint box mounting seat 33 is in sliding connection with the linear guide rail, the paint box mounting seat 33 is connected to the synchronous belt 322, and the PLC is in electrical connection with the driving motor 321.

[0051] In the above embodiment, the paint box mounting seat 33 is driven to move on the linear guide rail by the mode that the motor drives the synchronous belt 322 to move, and this structure can improve the position adjustment accuracy and efficiency of each paint box mounting seat 33.

[0052] As an optional embodiment, the telescopic rod 313 is a gas spring, a gas cylinder, a hydraulic cylinder or an electric push rod.

[0053] As an optional embodiment, the paint box mounting seat 33 includes a fixed part 331 and a movable part 332. The fixed part 331 is fixedly connected to the synchronous belt 322, and the movable part 332 is pivotally connected to the fixed part 331 through a second pivot shaft 35. The axial direction of the second pivot shaft 35 is the Y direction.

[0054] In the above embodiment, the second pivot shaft 35 can be further provided with a locking device. Through the structure that the movable part 332 is pivotally connected to the fixed part 331, the inclination angle of the paint box body 34 can be flexibly adjusted as needed, and the adjustment range of the inclination angle is about 20-40 degrees.

[0055] As an optional implementation, the other side of the turnover cross frame 314 is provided with a first clamping jaw 3141, and the second side support base 312 is pivoted with a second clamping jaw 3121 through a third pivot shaft 316, and the second clamping jaw 3121 is used for mutual clamping or separation with the first clamping jaw 3141.

[0056] In the above implementation, the mutual clamping structure of the first clamping jaw 3141 and the second clamping jaw 3121 realizes the mutual switching of the turnover cross frame 314 between the first state and the second state.

[0057] In the first state, the first clamping jaw 3141 and the second clamping jaw 3121 are locked, so that the turnover cross frame 314 is horizontally erected above the roller conveyor 2.

[0058] In the second state, only the first clamping jaw 3141 and the second clamping jaw 3121 need to be loosened, so that the turnover cross frame 314 is lifted upward and inclined at a certain angle under the action of manual pushing or through the pushing of the telescopic rod 313, with reference to Figure 3 This structure makes the switching of the turnover cross frame 314 between the two states more convenient and can provide good stability for the turnover bracket 31 in the first state.

[0059] As an optional implementation, a torsional spring is connected between the second clamping jaw 3121 and the third pivot shaft 316.

[0060] Since the torsional spring is connected between the second clamping jaw 3121 and the third pivot shaft 316, the elastic potential energy of the torsional spring can be used to make the first clamping jaw 3141 and the second clamping jaw 3121 self-locking stably in the first state, thereby improving the stability.

[0061] As an optional implementation, a push rod 3122 is connected to the Y direction of the second clamping jaw 3121.

[0062] In the above implementation, the structure of the push rod 3122 combined with the torsional spring makes the user only need to push the push rod 3122 when adjusting the turnover cross frame 314 to the second state, so that the second clamping jaw 3121 rotates and the locking between the first clamping jaw 3141 and the second clamping jaw 3121 is released.

[0063] As an optional implementation, the turnover cross frame 314 is connected with a handle 3142.

[0064] In the above implementation, the handle 3142 can be arranged on the side close to the second side support base 312, so as to facilitate manual holding of the handle 3142 to control the switching of the turnover cross frame 314 between the first state and the second state.

[0065] The above merely illustrates the embodiments of the present application, and is not intended to limit the patent scope of the present application. Any equivalent transformation or direct or indirect application in the related technical field based on the content of the present application specification and drawings is also included in the patent protection scope of the present application.
