The total control valve 5 comprises connecting pipe 51, stop valve 52 and three tee junction spare 53, and the grout box 1 bottom is connected to connecting pipe 51 one end, and the other end connects gradually stop valve 52 and three tee junction spare 53, and the third connector of every tee junction spare 53 all is connected with a pipe 2, and a lineation subassembly 4 is connected respectively to the other end of three pipes 2. The three scribing assemblies 4 can be slidably and rotatably arranged on the adjusting frame 3, the adjusting frame 3 is arranged on two sides of the conveying device 6 in a spanning mode, and the scribing assemblies 4 are suspended above the conveying device 6. The slurry is stored in the slurry box 1, and after the stop valve 52 is opened, the slurry flows into the three guide pipes 2 through the three-way connectors 53 respectively and reaches the three scribing assemblies 4. Slurry can flow out of the discharge end of each scribing component 4 and be smeared on the tire tread carried by the conveying device 6, the scribing component 4 is not moved, and the tire tread moves along with the conveying device 6 to generate a linear track, so that the scribing operation of the tire tread is completed.

The carton 1 is optimised so that the carton 1 can provide sufficient pressure to the slurry to maintain the flow of slurry within the conduit 2 and within the score assembly 4. The paste box 1 is composed of a box body 11 and a piston assembly 12, and the piston assembly 12 comprises a piston plate 121 and a sealing ring 122. A seal ring 122 is mounted around the circumferential edge of the piston plate 121. When the piston plate 121 is placed in the box body 11 in parallel with the bottom plate of the box body 11, the circumferential side wall of the piston plate 121 and the inner wall of the box body 11 are filled and sealed by the sealing ring 122, so that the piston plate 121, the inner wall of the box body 11 and the bottom plate of the box body 11 are enclosed to form the hydraulic chamber 13 with airtight characteristic, and the slurry is stored in the high hydraulic chamber 13. As the slurry in the hydraulic chamber 13 gradually flows out from the bottom, the piston plate 121 compresses the space of the hydraulic chamber 13 downward by its own weight, so that the pressure in the hydraulic chamber 13 is always maintained at a value equal to the gravity of the piston plate 121 itself. The flow balance of the slurry output by the discharge end of the scribing component 4 is ensured, and the problem of uneven scribing width is avoided.

The sealing ring 122 is made of a silicone material or a rubber material, and has an excellent airtight property to prevent the pressure loss of the hydraulic chamber 13 due to air leakage. While having sufficient elastic deformability to allow the piston plate 121 to move downward under gravity to compress the space of the hydraulic chamber 13 for pressure retention.

To prevent the tilting of the piston plate 121 from causing the loss of the air-tight property of the hydraulic chamber 13, the piston assembly 12 is further provided with a stopper 123 and a retaining rod 124. The limiting frame 123 is a rod body which is transversely arranged above the piston plate 121, two ends of the rod body are fixedly connected with the inner wall of the box body 11, a limiting hole 125 is formed in the limiting frame 123, and a limiting ring structure can also be adopted. The bottom end of the retaining rod 124 is vertically fixed to the top of the piston plate 121, and the top end thereof is disposed through the stopper hole 125 or the stopper ring. The holding rod 124 and the piston plate 121 are constrained by the limiting hole 125 when moving synchronously in the box body 11, so that the piston plate 121 can only keep the posture that the surface of the piston plate 121 is parallel to the bottom plate of the box body 11 to move up and down in the vertical direction.

The adjusting frame 3 is used for adjusting the positions and the scribing heights of the three scribing assemblies 4 so as to correspondingly determine the scribing positions and the scribing quality on the tire treads. The adjusting bracket 3 is composed of two bases 31, a shaft 32 and three positioning sleeves 33. The two bases 31 are symmetrically arranged at two sides of the conveying device 6, and two ends of the shaft lever 32 are respectively fixedly connected with the two bases 31, so that the shaft lever 32 is transversely arranged above the conveying device 6 and used as a guide rail of the three scribing assemblies 4. The three positioning sleeves 33 are respectively and correspondingly fixedly connected with the three scribing assemblies 4. The positioning sleeve 33 is fitted over the shaft 32. The switch on the positioning sleeve 33 is a bolt penetrating through the sleeve, one end of the bolt in the inner cavity of the positioning sleeve 33 is abutted against the shaft rod 32, and one end of the bolt outside the positioning sleeve 33 can be provided with a handle for convenient operation. By rotating the handle, the position and angle of the bolt which is pressed against the shaft lever 32 to lock the positioning sleeve 33 can be controlled, and the bolt can be controlled to be separated from the shaft lever 32, so that the positioning sleeve 33 can freely slide and rotate on the shaft lever 32 to adjust the position and angle.

The three scribing assemblies 4 are identical in structure, and each scribing assembly 4 is composed of a rigid pipe 41, a flow control valve 42 and a scribing needle 43. The outer wall of the hard tube 41 is fixedly connected with the outer wall of the positioning sleeve 33, one end of the hard tube 41 is communicated with the guide tube 2, and the other end of the hard tube 41 is sequentially communicated with the flow control valve 42 and the scribing needle 43. The slurry flows into the hard tube 41 from the conduit 2, and flows out of the needle hole of the scribing needle 43 after being subjected to flow rate adjustment by the flow rate control valve 42. Can regulate and control the flow of thick liquids through flow control valve 42, under the prerequisite that the whole journey of mucilage glue box 1 can provide sufficient pressure, flow control valve 42 only needs the flow control with thick liquids in the within range that suits, and can not cause the problem that the actual flow of thick liquids is less than flow control valve 42's the flow that passes through because of source pressure is not enough.

Compared with the existing scribing needle 43 with the inner diameter of 4mm, the scribing needle 43 adopted in the embodiment has the inner diameter of 1 mm. The thinner needle holes are beneficial to reducing the volatilization of gasoline in the slurry and are not easy to agglomerate, and the probability of blocking each pipeline is greatly reduced.

The grout box 1 is lifted by the support 7, so that the bottom of the grout box 1 is higher than each scribing component 4. Creating a liquid level difference. The slurry flow can be increased when the slurry level in the slurry box 1 is higher.

The three guide pipes 2 are all rubber hoses, and each guide pipe 2 is reserved with redundancy, so that the three scribing assemblies 4 can have a large moving range on the adjusting frame 3. The three scoring assemblies 4 are prevented from being restricted to the length of the catheter 2 and cannot be moved to the desired scoring position.

Various technical features in the above embodiments may be arbitrarily combined as long as there is no conflict or contradiction in the combination between the features, but is limited to the space and is not described one by one.

The present invention is not limited to the above embodiment, and various modifications and variations of the present invention are intended to be included within the scope of the claims and the equivalent technology if they do not depart from the spirit and scope of the present invention.
