Description

Technical Field

[0001] The utility model belongs to the technical field of tire detection, and particularly relates to a surface marking device for pressing out a tire tread. Background Art

[0002] For the stretch monitoring of TBR and PCR extrusion lines in the tire industry, a 500mm ruler is used to print at the exit of the extrusion line, and then the print spacing is measured at the key point position, and the spacing of each section is compared and analyzed.

[0003] The original measuring device was a measuring ruler with a spacing of 500 mm. The ruler was used to mark the tread surface near the exit of the extrusion line, and then the calibration spacing was measured at the key point. The above marking method will have manual errors, and the ruler is processed by itself, with poor accuracy and easy deformation, resulting in inaccurate measurement. Utility Model Content

[0006] Furthermore, two right-angle fixing rods are fixedly arranged on the mounting frame, and a marking wheel is rotatably fitted between the vertical parts of the two right-angle fixing rods.

[0007] Furthermore, an angle adjustment rod is fixedly provided on one side of the rotating shaft, and the angle adjustment rod is set at an obtuse angle; a working fixed plate and a non-working fixed plate are also fixedly provided on the support frame located on the same side of the angle adjustment rod, and through holes are provided at both ends of the angle adjustment rod, the working fixed plate and the non-working fixed plate.

[0008] Furthermore, the scoring teeth are in the shape of a quadrangular pyramid, and the dimensions of the trapezoidal surface are: upper base 1 mm, lower base 0.4 mm, and height 2 mm.

[0009] The utility model provides a surface marking device for extruded tread, which has the following beneficial effects:

[0011] 2. The marking spacing is more accurate;

[0012] 3. Tensile measurement is more convenient and can increase the frequency of testing. Previously, it was measured once a week, but now it has been changed to testing at the beginning of the class.

[0019] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments to help understand the content of the present invention. The methods used in the present invention are all conventional methods unless otherwise specified; the raw materials and devices used are all conventional commercial products unless otherwise specified.

[0020] like Figure 1 As shown in Figure 2, the utility model provides a surface marking device for an extruded tread, including a support frame 2, a conveying roller 1 is rotatably fitted between the support frame 2, and the conveying roller 1 transports the extruded tread 13. A fixed plate 3 is provided on the support frame 2, a rotating shaft 4 is rotatably fitted on the fixed plate 3, a square tube 5 is fixedly provided on the rotating shaft 4, and a mounting frame 7 is slidably fitted on the square tube 5. By using the square tube 5, the mounting frame 7 can be limited in the radial direction of the square tube 5 without relative sliding. Two right-angle fixed rods 8 are fixedly provided on the mounting frame 7, and a marking wheel 6 is rotatably fitted between the vertical parts of the two right-angle fixed rods 8, and the marking wheel 6 is pressed against the extruded tread 13. By providing the right-angle fixed rods 8, the horizontal force on the marking wheel 6 is minimized when rolling, and the horizontal lateral movement is avoided, thereby reducing the distance error of the marking. The marking wheel 6 is fixedly provided with engraved sharp teeth 12 on the contact surface with the extruded tread 13. As shown Figure 4 As shown, the scoring teeth 12 are in the shape of a quadrangular pyramid, and the dimensions of the trapezoidal surface are: upper base 1 mm, lower base 0.4 mm, and height 2 mm.

[0021] When in use, the mounting frame 7 is slid above the extruded tread 13, so that the marking wheel 6 is pressed against the extruded tread 13, and the marking wheel 6 follows the extruded tread 13 on the conveying roller 1 to rotate. Each time the marking wheel 6 rotates one circle, the scoring teeth 12 will leave a scratch mark on the extruded tread 13. When the extruded tread 13 is tested for stretchability, the distance between adjacent marks is measured. If the difference between the distance between adjacent marks and the circumference of the marking wheel 6 is less than 10 mm, it means that the extruded tread 13 is not stretched.

[0022] like Figure 3 As shown, an angle adjustment rod 9 is fixedly provided on one side of the rotating shaft 4, and the angle adjustment rod 9 is set at an obtuse angle. A working fixing plate 10 and a non-working fixing plate 14 are also fixedly provided on the support frame 2 located on the same side of the angle adjustment rod 9, and through holes are provided on both ends of the angle adjustment rod 9, the working fixing plate 10 and the non-working fixing plate 14. When the working fixing plate 10 is fixed in cooperation with the angle adjustment rod 9, the marking wheel 6 can be pressed against the extruded tread 13; when the non-working fixing plate 14 is fixed in cooperation with the angle adjustment rod 9, the marking wheel 6 tilts upward and is separated from the extruded tread 13.

[0023] When it is necessary to mark the extruded tread 13, the angle adjustment rod 9 is rotated to the position of the working fixed plate 10, and the pin 11 passes through the through holes of the angle adjustment rod 9 and the working fixed plate 10, thereby limiting the rotating shaft 4 to prevent the rotating shaft 4 from rotating again; when it is not necessary to mark the extruded tread 13, the angle adjustment rod 9 is rotated to the position of the non-working fixed plate 14, and the pin 11 passes through the through holes of the angle adjustment rod 9 and the non-working fixed plate 14, thereby limiting the rotating shaft 4.

[0024] In the description of the present invention, it should be understood that the terms "left", "right", "up", "down", "top", "bottom", "front", "back", "inside", "outside", "back", "middle", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0025] However, what is described above is only a specific embodiment of the present invention and should not be used to limit the scope of implementation of the present invention. Therefore, the replacement of equivalent components, or equivalent changes and modifications made according to the scope of protection of the patent of the present invention should still fall within the scope covered by the claims of the present invention.
