Description

Technical Field

[0001] The utility model relates to the technical field of tire cord layer processing, in particular to a novel ultrasonic fiber cord cutting machine. Background Art

[0002] Tire cord is an essential component in tire production. It is mainly woven or arranged from high-strength, wear-resistant fiber materials. During processing, the cord needs to be cut into the required size and welded after cutting.

[0003] The main function of the existing cord cutting device is to cut the cord and then transfer the cut cord to the welding equipment for welding. However, there is no direct connection and coordination between the two mechanisms, because after the cord is cut, it needs to be separated, that is, the cut cord is separated and then transferred to the welding mechanism for welding. Therefore, in the traditional cutting process, a separation mechanism and a transfer mechanism need to be set between the two, which also causes the entire cutting processing production line to occupy too much space and be not compact enough, and also causes the coordination between the various mechanisms to be not close enough. Therefore, it is necessary to propose a new ultrasonic fiber cord cutting machine. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a novel ultrasonic fiber cord cutting machine.

[0005] The utility model adopts the following technical solutions: a frame and a workbench arranged on one side of the frame, the frame is provided with a curtain fabric conveying and seam separation mechanism and an ultrasonic cutter capable of angle adjustment and displacement, the workbench is provided with a curtain fabric welding mechanism and a curtain fabric splicing manipulator, thereby realizing the cutting, seam separation, transfer splicing and welding of the curtain fabric;

A lifting slide is provided on the second slide, and the lifting seat of the lifting slide rail is fixedly connected to the ultrasonic cutter.

[0010] As a further improvement of the above-mentioned scheme, the angle adjuster includes a motor arranged at the bottom of the frame, and an adjusting rod rotatably installed above the frame. The output shaft of the motor is transmission-connected to the adjusting rod. Connecting strips are slidingly provided at both ends of the adjusting rod. The two connecting strips are respectively hinged to the feed belt conveyor and the discharge belt conveyor.

[0011] As a further improvement of the above solution, a heavy-loaded hollow rotating platform is provided at the bottom of the workbench, and the rotating frame is fixedly mounted on the heavy-loaded hollow rotating platform, so that the rotating frame is driven to rotate by the heavy-loaded hollow rotating platform.

[0012] As a further improvement of the above scheme, the bottom of the pressure plate frame is hinged to the rotating frame, and multiple pressure plate cylinders are hinged on the rotating frame. The conveying rods of multiple pressure plate cylinders are all hinged to the pressure plate frame. The pressure plate frame can be driven to press the curtain in an inclined manner through the extension and retraction of the pressure plate cylinders.

[0015] As a further improvement of the above solution, a plurality of lifting cylinders are provided on the rotating frame, and the output rods of the plurality of lifting cylinders are fixedly connected to the bottom of the ultrasonic welding head, thereby driving the ultrasonic welding head to rise and contact the cord to be welded.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] By integrating the cord conveying and seam separation mechanism with the ultrasonic cutter, and then integrating it with the cord welding mechanism, and setting a cord splicing robot for transferring and splicing cords between the cutting mechanism and the cord welding mechanism, the structure of the cord cutting production equipment is made more compact, and the correlation between different mechanisms is also strengthened. This not only reduces the occupied space and increases the coordination between the various mechanisms, but also improves the processing efficiency of the cord.

[0018] Since the curtain fabric conveying and slitting mechanism is also provided with an angle adjuster, when the curtain fabric is deflected, the angle of the curtain fabric can be adjusted, so that the curtain fabric can be cut more regularly;

[0019] The ultrasonic cutter, which consists of a transducer, an amplitude modulation rod and a knife body, has lower blade wear than traditional cutters, which can increase the service life of the tool and is less likely to produce flying chips when cutting the curtain fabric.

DETAILED DESCRIPTION

[0026] The present invention will be further described below with reference to the accompanying drawings and specific implementation methods.

[0027] Please combine Figures 1 to 4The new ultrasonic fiber curtain fabric cutting machine includes: a frame 1 and a workbench 11 arranged on one side of the frame 1, the frame 1 is provided with a curtain fabric conveying and seam separation mechanism and an ultrasonic cutter capable of angle adjustment and displacement, the workbench 11 is provided with a curtain fabric welding mechanism and a curtain fabric splicing robot, the curtain fabric splicing robot is composed of a robot rotating seat 12, a robot main arm 13 and a vacuum suction cup 14, the robot rotating seat 12 and the robot main arm 13 are responsible for controlling the position of the vacuum suction cup 14, and the vacuum suction cup 14 is responsible for sucking the cut curtain fabric and then transferring the curtain fabric to the splicing table 17, thereby realizing the cutting, seam separation, transfer splicing and welding of the curtain fabric;

[0028] The ultrasonic cutting knife is composed of a transducer 8, an amplitude modulation rod 9 and a knife body 10;

[0029] The curtain conveying and separating mechanism includes a feed belt conveyor 2 and a discharging belt conveyor 3 movably arranged on the frame 1 and a rotatable angle adjuster 4, the angle adjuster 4 includes a motor arranged at the bottom of the frame 1 and an adjusting rod rotatably installed above the frame 1, the output shaft of the motor is transmission-connected to the adjusting rod, and connecting bars 401 are slidably provided at both ends of the adjusting rod, and the two connecting bars 401 are hinged to the feed belt conveyor 2 and the discharging belt conveyor 3 respectively, the feed belt conveyor 2 and the discharging belt conveyor 3 are both composed of a slide and a plurality of conveyor belts of different lengths, and the joint of the feed belt conveyor 2 and the discharging belt conveyor 3 adopts an inclined layout, which can ensure that when the curtain is conveyed, the distance between the feed belt conveyor 2 and the discharging belt conveyor 3 will not be too large due to the adjustment of the angle of the angle adjuster 4, thereby causing the curtain to be unable to be smoothly conveyed from the feed belt conveyor 2 to the discharging belt conveyor 3;

[0030] The curtain welding mechanism includes a rotating frame 15 rotatably mounted on the workbench 11, and a splicing table 17, a liftable pressing plate frame 16 and an ultrasonic welding head 18 are provided on the rotating frame 15. The ultrasonic welding head 18 is provided with an ultrasonic generator and a transducer. The ultrasonic generator converts the 50Hz current into 20~40KHz electrical energy, which is then converted into mechanical vibration of the same frequency through the transducer, and then the mechanical vibration is transmitted to the welding head. The welding head will receive the 20~40KHz high-frequency vibration energy and transmit it to the joint of the workpiece to be welded, so that the surface of the workpiece also generates high-frequency vibration. When the vibration amplitude of the workpiece surface is large enough, friction heat will be generated, which will melt the surface material of the workpiece, thereby combining the two workpieces together to complete the welding.

[0031] Two first slide rails 5 are provided on the frame 1, and a movable first slide seat is provided on each of the two first slide rails 5. A second slide rail 6 is rotatably connected to each of the two first slide seats. A second slide rail 6 is provided on the second slide seat, and a lifting slide rail 7 is provided on the second slide seat. The lifting seat of the lifting slide rail 7 is fixedly connected to the ultrasonic cutter.

[0032] Through the above technical solution, when the two first slides move in opposite directions, the entire second slide rail 6 together with the ultrasonic cutter will be set obliquely on the frame 1, so that the ultrasonic cutter can cut the curtain with an inclined cut, thereby adapting to different cutting needs.

[0033] A heavy-load hollow rotating platform is provided at the bottom of the workbench 11 , and the rotating frame 15 is fixedly mounted on the heavy-load hollow rotating platform, so that the rotating frame 15 is driven to rotate by the heavy-load hollow rotating platform.

[0034] The bottom of the pressing plate frame 16 is hinged to the rotating frame 15, and multiple pressing plate cylinders are hinged on the rotating frame 15. The conveying rods of multiple pressing plate cylinders are all hinged to the pressing plate frame 16. The pressing plate cylinders can be extended and retracted to drive the pressing plate frame 16 to press the curtain in an inclined manner.

[0035] The workbench 11 is provided with a circular opening, and the splicing table 17 is located in the circular opening and is rotatably connected to the circular opening, so that the splicing table 17 can extend to the top of the workbench 11 and drive the cord to be welded to be adjusted.

[0036] A welding seam is provided on the splicing platform 17 , and the ultrasonic welding head 18 corresponds to the welding seam, so that the ultrasonic welding head 18 can be raised from the bottom of the splicing platform 17 through the welding seam.

[0037] The rotating frame 15 is provided with a plurality of lifting cylinders, and the output rods of the plurality of lifting cylinders are fixedly connected to the bottom of the ultrasonic welding head 18, thereby driving the ultrasonic welding head 18 to rise and contact the cord to be welded.

[0038] The implementation principle of a new ultrasonic fiber cord cutting machine in the embodiment of the present application is:

[0039] When the curtain needs to be cut, the curtain is placed on the feeding belt conveyor 2. When the feeding belt conveyor 2 drives the curtain to move under the ultrasonic cutter, the lifting slide 7 is started to drive the blade 10 of the ultrasonic cutter to descend until the blade 10 contacts the curtain. Then the second slide 6 drives the ultrasonic cutter to move, so that the blade 10 cuts the curtain while moving horizontally. During the cutting process, the feeding belt conveyor 2 is in a stopped state.

[0040] When the cut portion of the cord is conveyed to the discharge belt conveyor 3, the discharge belt conveyor 3 drives the cut cord to move, thereby separating the cut cord from the cord to be cut on the feed belt conveyor 2;

[0041] When the cut curtain moves to the range of the curtain splicing robot, the curtain splicing robot sucks it up through the vacuum suction cup 14 and transfers it to the splicing table 17 on the workbench 11, so that the front end of the cut curtain contacts the tail end of the welded curtain on the splicing table 17, and the head and tail of the two are in a superimposed state, and then the pressure plate frame 16 presses the two, and the ultrasonic welding head 18 starts to weld the two.

[0042] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
