[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] A non-woven fabric welding and cutting integrated device comprises a workbench 100, a housing 1, and a base 11. The housing 1 is provided with the base 11 at the bottom, and specifically, the base 11 is in the shape of a door. A motor 110 is provided in the housing 1, and a driving sprocket 111 is provided on the output shaft of the motor 110. The driving sprocket 111 is connected to a driven sprocket 12 through a chain 13. A roll welding wheel 2 is provided on the outer side of the base 11, and a welding platform 200 is provided below the roll welding wheel 2.

[0021] The central axis 23 of the roll welding wheel is rotatably connected to the base 11 through the bearing 19. A cutter seat 8 is sleeved on the central axis 23 between the roll welding wheel 2 and the base 11, and the cutter seat is movably connected to the base to radially move and adjust the position. A cutter 3 is installed on the cutter seat 8.

[0022] A specific implementation is: the cutter seat 8 includes a cutter seat flange 81 and a cutter seat sleeve 82, wherein the cutter seat flange 81 is arranged at one end of the cutter seat sleeve 82, and the outer side of the cutter seat flange 81 is close to the inner side of the roll welding wheel 2.

[0023] The other end of the cutter seat sleeve 82 is provided with a thread, and a locking nut 83 is screwed on the thread. The cutter seat sleeve 82 is provided with an annular cutter 3 and a bearing 7. The bearing 7 is provided with an eccentric wheel 4, and a plurality of screw holes are provided on the outer periphery of the eccentric wheel 4. Specifically, the depth of the blade of the annular cutter 3 exceeding the eccentric wheel 4 varies with the contour line of the eccentric wheel.

[0024] The outer seat body of the base 11 is provided with a hinge shaft 53, and an arc baffle 5 is hinged on the hinge shaft 53. The power arm of the arc baffle 5 is fixed to a screw hole 41 on the outer periphery of the eccentric wheel 4 by a screw 65. Since a plurality of screw holes 41 are provided on the outer periphery of the eccentric wheel 4, the power arm is fixed to different screw holes 41, so that the blade depth can be selected.

[0025] The outer end of the arc-shaped baffle power arm is movably arranged on the screw seat 6 outside the base 11.

[0026] Specifically, a screw 63 is fixed to the outer end of the arc baffle power arm, the screw 63 passes through the screw seat 6, a nut 62 is screwed on the end of the screw 63, and a spring 61 is sleeved between the screw 63 and the screw seat 6. In this way, the height of the arc baffle 5 and the eccentric wheel 4 can be adjusted by adjusting the nut 62.

[0027] The upper ring of the roll welding wheel 2 is provided with two tooth-shaped stripes 22 and a smooth stripe 21. The lower part of the roll welding wheel 2 is provided with an ultrasonic welding head 101. The roll welding wheel central axis 23 and the roll welding wheel 2 are an integral structure.

[0028] The outer side surface of the cutter seat flange 81 is close to the inner side surface of the roll welding wheel 2, and the roll welding wheel 2 drives the cutter seat to rotate by relying on the friction force.

[0029] The base is in the shape of a gate, and the central axis of the roll welding wheel is rotatably connected to the outer seat body of the base through a bearing, and the central axis of the roll welding wheel is rotatably connected to the inner seat body of the base through a bearing. In order to adjust the friction force, a tie rod bolt 17 is screwed on the outer end of the central axis 23, and the head of the tie rod bolt 17 is pressed on the inner ring of the bearing, and the bearing is fixed on the stop on the inner seat body of the base 11. The central axis 23 is set shorter and has an adjustable distance from the tie rod bolt 17. The tie rod bolt 17 can form an adjustable tension on the central axis 23 with the help of the bearing.

[0030] In addition, a specific implementation method also includes: the eccentric wheel is replaced by a circular wheel, the position of the eccentric wheel or the circular wheel can be adjusted by directly adjusting the eccentric wheel or the circular wheel with the base by a screw, and the adjustment can also be achieved by pressing a strip pressure plate on the eccentric wheel or the circular wheel.

[0031] Ultrasonic welding machine is to transmit ultrasonic waves to the plastic welding workpiece through the welding head, with a high frequency of 20KHZ-15KHZ and a certain amplitude, so that the two plastic joint surfaces are rubbed violently and melted, and the gluing process is completed instantly. Ultrasonic plastic welding machine can also be used for spot welding, riveting, inlaying, cutting, embedding, molding, edge filling and other processing technologies by replacing the welding head. It is suitable for welding plastics such as polyethylene (GL), ABC, polyacetal, polycarbonate, etc.

[0032] A guide wheel 9 is provided at the rear of the roll welding wheel 2, and the guide wheel 9 is rotatably arranged at the bottom end of a bracket 10, and the other end of the bracket 10 is arranged on the housing 1. The axis of the guide wheel 9 is arranged parallel to the axis of the roll welding wheel 2. Specifically, the bracket 10 is adjustable and is formed by a horizontal base rod 92 and a vertical fixed rod 91 that are movably connected.

[0033] Its working principle is: two pieces of non-woven fabrics are stacked neatly and the edge welding operation is performed on the workbench 100. The power supply of the motor 110 is turned on, so that the active sprocket 111 drives the sprocket 12 to rotate through the chain 13, and the sprocket 12 drives the central shaft 23 to rotate in the bearing of the base. The central shaft 23 simultaneously drives the annular cutter 3 and the roll welding wheel 2 on the cutter seat 8 to rotate at high speed, so as to perform edge pressing roll welding and edge trimming on the edge of the non-woven fabric. The two tooth-shaped stripes 22 on the roll welding wheel 2 perform large-area welding on the stacked two layers of non-woven fabrics, and the smooth stripes 21 simultaneously perform gapless heat welding on the non-woven fabrics to form a gapless weld, which greatly improves the sealing and waterproof performance of the two non-woven fabrics.

[0034] When adjusting the height of the arc baffle 5, the eccentric wheel 4 will be adjusted together. Since the annular cutter 3 and the bearing of the eccentric wheel are coaxially arranged, the height of the annular cutter 3 will also be adjusted together. In this way, the feed depth can be adjusted in time after the annular cutter is worn, so as to improve the cutting quality of the cutter.

[0035] The welded and cut nonwoven fabric is guided and pulled by the guide wheel 9, and finally the welded nonwoven fabric is obtained.

[0036] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
