Description

Technical Field

[0001] The utility model relates to the technical field of solid tires, in particular to a solid tire Dutch belt strip cutting machine. Background Art

[0002] The carcass of a solid tire is solid. The solid tire adopts an advanced three-stage structural design, and the three types of rubber are base rubber, tire core rubber, and tread rubber.

[0003] Base rubber: High-rigidity, high-strength base rubber and wire ring support ensure both the stiffness of the tire and the tightness of the tire and the rim.

[0004] Tire core rubber: Highly elastic tire core rubber effectively absorbs the vibration generated when the vehicle is running.

[0005] Tread rubber: The thickened tread rubber layer ensures the tire's tear and wear resistance and increases the service life of the solid tire.

[0006] The solid tire and the rim are pressed together through an interference fit, and imported fiber rubber (Dutch tape) is used as the tire base rubber. The Dutch tape is a mixture of fiber cords, steel cords and other skeleton materials that are crushed after the rubber is applied and pressed with rubber. It has a certain hardness of the mixture film, which has the advantages of good rigidity, high hardness, small deformation, low heat generation, etc. It improves the heat generation performance of the tire and reduces the slippage caused by the expansion of the hub due to the heat generation of the tire.

[0007] The bottom layer of the solid tire adopts a reinforced rectangular steel bead structure to make the pressure distribution between the tire and the rim more even and the fit tighter. In order to ensure the uniform spacing between the steel bead rings, the Dutch tape strips need to be filled between the steel bead rings. Therefore, the Dutch tape should be cut into strips of uniform width.

[0008] In order to facilitate cutting Dutch tape into strips, ensure cutting width, improve production efficiency and reduce labor intensity, a Dutch tape cutting machine was designed and manufactured.

[0009] For this reason, a solid tire Dutch belt strip cutting machine is proposed. Summary of the invention

[0012] A knife roller is provided below the groove roller, one side of the knife roller is rotatably connected to the chassis, the other side of the knife roller is rotatably connected to a sliding plate, the sliding plate is slidably connected to the bracket, a plurality of disc knives are evenly installed on the knife roller, and the disc knives are embedded in the grooves on the groove roller.

[0013] Preferably, a baffle slide is installed on the front surface of the bracket, a baffle is slidably connected to the baffle slide, and bolts for fixing the position are installed on the baffle.

[0014] Preferably, adjustment rods are symmetrically mounted on the upper surface of the bracket, and the top ends of the adjustment rods pass through the top of the frame.

[0015] Preferably: a motor for driving the knife roller to rotate is installed on one side of the bottom of the chassis, and a switch for controlling the start and stop of the device is installed on the front surface of the chassis.

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0024] Example

[0025] See also Figure 1The utility model provides a technical solution: the chassis 2 is made of welded steel. The frame 4 is fixed on the chassis 2, the knife roller 12 and the disc knife 14 are driven by the motor 1, and the groove roller 9 is a driven roller. The knife roller 12 and the groove roller 9 rotate in opposite directions.

[0026] The disc cutter 14 is made of tool steel and has a hardness of HRC52-55 after heat treatment. The spacing between 5-6 disc cutters 14 is kept consistent. The disc cutter 14 is installed on the roller shaft of the knife roller 12. When assembled with the groove roller 9, the blade of the disc cutter 14 should be embedded in the groove of the groove roller 9 by about 1-2 mm to facilitate cutting and separation. The embedding depth can be adjusted according to the cutting situation of the Dutch belt.

[0027] When the Dutch belt is cut into strips, it enters between the knife roller 12 and the groove roller 9. If the spacing is not appropriate, the bolts used to fix the sliding plate 15 can be loosened, and then the bracket 8 can be driven by the rotation of the adjusting screw 6 to move the groove roller 9 up and down. After adjusting to the appropriate position, the bolts can be tightened again to fix the position between the sliding plate 15 and the bracket 8.

[0028] A baffle 11 is provided in front of the groove roller 9, and the baffle 11 moves left and right on the baffle slide 10, and the number of cut strips and the cutting width can be adjusted according to the width of the Dutch belt.

[0029] Guard plates 13 are provided before and after the knife roller 12 to prevent the disc knife 14 from breaking when cutting strips, thereby protecting personal safety.

[0030] An emergency stop switch 7 is provided on the frame 4. When the machine is in a dangerous state, the power supply is cut off by the emergency stop switch 7 to stop the operation of the equipment.

[0031] Put the Dutch tape of fixed length between the groove roller 9 and the knife roller 12, adjust the screw 6 to adjust the distance between the groove roller 9 and the knife roller 12, start the switch 3, the knife roller 12 drives the disc knife 14 to rotate, and the groove roller 9 rotates in the opposite direction, driving the Dutch tape to pass through the gap between the two rollers and be cut into strips of a certain width.
