Description

Technical Field

[0001] This utility model relates to a cutting machine, and more particularly to an ultrasonic cutting machine for tire tread pads. Background Technology

[0002] Tire tread pads, sometimes called tread underlay or tread liner, are an important component of tire structure. Located beneath the tire tread, they sit directly between the tread rubber and the tire's reinforcing layers. Tread pads protect the tire's reinforcing layers from external damage, especially preventing sharp objects such as stones and glass shards from penetrating the tread and directly damaging the tire's internal structure. Precise cutting of the tread pads is an essential step in tire manufacturing. This process ensures the tread pads are cut to a precise shape that meets specific tire design and size requirements, guaranteeing a seamless fit in the intended position for optimal protection and improved overall tire performance.

[0003] Existing tire tread fabric cutting typically employs automated or semi-automated cutting equipment and techniques. The working principle mainly involves using high-precision cutting tools, such as laser cutters, waterjet cutters, or CNC cutters, combined with computer-aided design and computer-aided manufacturing systems to ensure the accuracy and consistency of the cutting path. However, in practice, this automated cutting solution still has certain limitations, especially when cutting thicker or longer tire tread fabrics. The first section of the tread fabric, having lost its original support, is easily tilted or deformed by gravity. This phenomenon disrupts the flatness of the fabric, resulting in uneven cut edges and consequently affecting the cutting quality of the tire tread fabric.

[0004] Therefore, there is a particular need for an ultrasonic cutting machine for tire tread pads to solve the problems existing in the prior art. Utility Model Content

[0024] First, the worker places the tire tread pad roll between two feeding plates 2. Then, one end of the tire tread pad is guided through the two conveying rollers 4. Subsequently, the motor 3 is turned on by the controller 23. The output shaft of the motor 3 drives the upper conveying roller 4 to rotate, so that it works in conjunction with the lower conveying roller 4 to smoothly convey the tire tread pad. When the conveyed tire tread pad reaches the predetermined length, the infrared sensor 701 detects the tire tread pad and immediately transmits a signal to the controller 23. The controller 23 quickly responds by turning off the motor 3. Then, the worker squeezes the knob 5 to rotate the bidirectional screw 6, which drives the slide rod 8 to move the cylinder 9, electric slide rail 10, and ultrasonic cutter 1001 upwards. During this process, the ultrasonic cutter 1001 is kept in place by the scale line 22. 01. When the ultrasonic cutter 1001 reaches the preset height, the rotation of the bidirectional screw 6 stops. Then, the cylinder 9 and electric slide rail 10 are activated. The telescopic rod of the cylinder 9 extends to a suitable length, driving the electric slide rail 10 to move the electric slider 1002, ultrasonic cutter 1001, and pressure plate 11 backward. This allows the ultrasonic cutter 1001 to contact the tire tread pad. During this process, the pressure plate 11 pre-contacts the tire tread pad and moves forward under force. The spring 12 is compressed, applying pressure to the pressure plate 11 to ensure it presses firmly against the tire tread pad, maintaining a smooth cut. Then, the ultrasonic cutter 1001 is activated to begin cutting the tire tread pad, while simultaneously controlling the electric slider 1002 to move the ultrasonic cutter... The ultrasonic cutter 1001 moves to its right limit to fully cut the tire tread pad. After cutting, the ultrasonic cutter 1001 is turned off, and the telescopic rod of the control cylinder 9 retracts to its initial state. This drives the electric slide rail 10 to move the electric slider 1002, the ultrasonic cutter 1001, and the pressure plate 11 forward. The pressure plate 11 disengages from the tire tread pad, and the spring 12 returns to its original position. At this point, the cut tire tread pad falls into the collection box 14 for collection. To continuously cut tire tread pads, the above steps can be repeated. The ultrasonic cutter 1001 generates a lot of heat during prolonged operation. Operators must ensure that the electric slider 1002 moves the ultrasonic cutter 1001 to its right limit to ensure... With the slide bar 8 at a suitable height, the ultrasonic cutter 1001 is aligned with the opening 101. Then, the telescopic rod of the cylinder 9 is extended to a suitable length, allowing the ultrasonic cutter 1001 to enter the housing 1 through the opening 101 and be positioned between the nozzle 19 and the water collection tank 20. Next, the prepared external water pipe is connected to the water inlet 16, allowing water to enter the water storage tank 15 from the water inlet 16. Then, the water pump 17 is turned on, and the water pump 17 transports the water in the water storage tank 15 to the water supply pipe 18, so that the water is finally sprayed from the nozzle 19 onto the ultrasonic cutter 1001, thereby water cooling the ultrasonic cutter 1001 to prevent the ultrasonic cutter 1001 from overheating and affecting its normal operation. During the cooling process, the used water flows into the water collection tank 20.The water is discharged through outlet 21. After cooling is complete, water pump 17 is turned off, the connection between the external water pipe and inlet 16 is disconnected, and finally, the telescopic rod of cylinder 9 is retracted, causing the ultrasonic cutter 1001 to exit from the housing 1, allowing the tire tread pad cutting operation to continue.
