[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1-6 As shown, the tread marking adjustment mechanism includes: a support mechanism 1, the main body of the support mechanism 1 is a rectangular plate structure, a second mounting seat 1011 is fixedly connected to the top surface of the support mechanism 1, a bearing seat 2 is embedded inside the second mounting seat 1011, and a transmission component 201 is embedded inside the bearing seat 2. The transmission component 201 is a lead screw structure.

[0026] The transmission assembly 201 has a moving seat 3 engaged on its outer side. A mounting plate 301 is fixedly connected to the top surface of the moving seat 3. The mounting plate 301 is longitudinally arranged and has a through hole inside, which is a limiting hole 3012. A positioning bolt 3011 is screwed onto the front end of the mounting plate 301. The positioning bolt 3011 is used to limit the dye pipe 3015. A splicing component 3013 is fixedly connected to the right side of the outer periphery of the moving seat 3. A guide seat 3014 is fixedly connected to the right side of the splicing component 3013. The guide seat 3014 has a ring structure, and a mounting plate 301 is also fixedly connected to the top of the outer periphery of the guide seat 3014. The dye pipe 3015 is inserted into the limiting hole 3012. The dye pipe 3015 is elastic. A dye head 3016 is fixedly connected to the left side of the movable seat 3. The dye head 3016 is a rigid component. A rotating rod 302 is rotatably connected to the left side of the movable seat 3. A connecting plate 3022 is fixedly connected to the top of the rotating rod 302. A guide frame 3023 is fixedly connected to the top of the connecting plate 3022. A longitudinal groove is opened inside the guide frame 3023. A limit block 3024 is fixedly connected inside the longitudinal groove. An arc-shaped groove is opened at the top of the limit block 3024. A longitudinally arranged spring 3025 is fixedly connected inside the guide frame 3023. A pressure block 3026 is fixedly connected to the bottom end of the spring 3025. An arc-shaped groove is opened at the bottom end of the pressure block 3026. A guide seat 3014 is slidably connected to the outside of the guide rod 2015. The guide rod 2015 is arranged parallel to the transmission assembly 201.

[0027] The support mechanism 1 has a first mounting base 101 fixedly connected to its top surface. The first mounting base 101 and the second mounting base 1011 are arranged in parallel. Two guide plates 1012 are fixedly connected to the outside of the support mechanism 1 in opposite directions. The guide plates 1012 have mounting holes 1013 that are bidirectionally connected to the top and bottom sides. A scale 2011 is fixedly connected to the front end of the first mounting base 101 located on the front side. The main body of the scale 2011 is an L-shaped structure.

[0028] The guide plate 1012 has a bidirectional through mounting hole 1013 on both the upper and lower sides. A scale 2011 is fixedly connected to the front end of the first mounting seat 101 on the front side. The main body of the scale 2011 is an L-shaped structure. Guide rods 2015 are fixedly connected to the inner sides of the two first mounting seats 101. The main body of the guide rod 2015 is a cylindrical structure. The main body of the guide seat 3014 is a screw structure. A nut 3021 is screwed onto the outer side of the rotating rod 302.

[0029] In use, the support mechanism 1 serves as the foundation of the entire device. Its rectangular plate structure provides a stable support plane. The first mounting base 101 and the second mounting base 1011 are fixed parallel to each other on the top surface of the support mechanism 1, providing precise positioning for the installation of subsequent components. The bearing seat 2 and the guide rod 2015 are respectively installed on the first mounting base 101 and the second mounting base 1011. The bearing seat 2 is used to support the transmission component 201, enabling it to rotate stably. The guide rod 2015 provides guidance for the movement of the movable seat 3, ensuring the stability and straightness of the movable seat 3 during movement. The guide plate 1012 on the outside of the support mechanism 1 not only serves to connect other equipment, but its internal mounting holes 1013 can also be used to fix the entire device to the workbench with bolts and other connecting parts, ensuring that the device will not shift during operation.

[0030] The transmission component 201 is a lead screw structure. A circular wheel 2012 is fixedly connected to the front end of the transmission component 201. A scale 2013 is fixedly connected in a circular array on the front surface of the wheel 2012. A handle 2014 is fixedly connected to the front end of the wheel 2012. The handle 201 has a cylindrical body. When the wheel 2012 is rotated, it drives the transmission component 201 to rotate. Since the transmission component 201 meshes with the outer side of the movable seat 3, according to the lead screw transmission principle, the rotating transmission component 201 causes the movable seat 3 to move linearly along the direction of the guide rod 2015. The mounting plate 301 on the top surface of the movable seat 3 moves accordingly. The limiting hole on the mounting plate 301... 3012 is used to connect to the dye pipe 3015. By moving the movable seat 3, the position of the dye pipe 3015 can be precisely adjusted, thereby changing the scribing position of the dye head 3016. The scale 2013 and handle 2014 on the front surface of the wheel 2012 make it convenient for operators to intuitively understand the rotation angle and displacement, achieve precise adjustment, and avoid the perpendicularity error caused by traditional ruler measurement. The wheel 2012 is equipped with a circular scale 2013, and a ruler 2011 is also fixedly connected to the front end of the second mounting seat 1011. By the relative position of the ruler 2011 and the scale 2013, the number of revolutions of the wheel 2012 can be determined to achieve the purpose of precise adjustment.

[0031] The positioning bolt 3011 screwed onto the front end of the mounting plate 301 is used to limit the dye pipe 3015. After the position of the dye pipe 3015 is adjusted, the positioning bolt 3011 is tightened. The end of the positioning bolt 3011 will press the dye pipe 3015. Because the dye pipe 3015 is elastic, it can be firmly fixed under the pressure of the positioning bolt 3011, preventing the dye pipe 3015 from shifting during the marking process and ensuring the accuracy of the marking position. Also, because the dye pipe 3015 is elastic, when the dye head 3016 of the sensitive component structure contacts the tread, because the rubber sheet sometimes has thickness errors, or there may be a certain amount of vertical jumping during its conveying, the spring component 3025 can well accommodate potential errors or potential vertical jumping. Most of the time, the weight of the dye head 3016 and even the force of the spring act on the limiting block 3024. Only when vertical jumping or errors occur for a short time will the spring component 3025 undergo elastic deformation to achieve automatic pressing.
