At this time, the worker starts the ultrasonic device 92, and due to the operation of the ultrasonic device 92, high-frequency vibration will be generated and transmitted to the welding head 10, and then transmitted to the first cloth 3 and the second cloth 4 through the welding head 10. Under the extrusion action of the welding head 10, the friction between the first cloth 3 and the second cloth 4 is large, and through vibration, high-frequency mutual friction between the first cloth 3 and the second cloth 4 is generated, thereby generating high temperature, so that the first cloth 3 and the second cloth 4 are fused. Before the welding head 10 contacts the first cloth 3 and the second cloth 4, the pulley 12 will first contact the first cloth 3 and the second cloth 4, and when the ultrasonic device 92 continues to move downward, the two pulleys 12 will move in opposite directions at the bottom of the first cloth 3 and the second cloth 4, and at this time the first spring 13 is in a state of elastic tension under the action of tension;

[0031] Through the air cylinder 91 driving the ultrasonic device 92 to move downward, the pulley 12 first contacts and extrudes the first cloth 3 and the second cloth 4, and at this time the two pulleys 12 move in opposite directions, and through the pulley 12 pulling the first cloth 3 and the second cloth 4 to both sides, the surface of the first cloth 3 and the second cloth 4 is flattened.

[0033] The working principle and beneficial effects of the above technical solution are that, due to the operation of the air cylinder 91, the ultrasonic device 92 and the shell 15 will move downward together, at this time, the vertical rod 17 and the second movable block 16 move downward relative to the shell 15, at this time, the second one-way valve 28 is in a closed state, the first one-way valve 18 is opened, and cold air is filled into the inside of the shell 15 through the second movable block 16, when the filling is completed, when the air cylinder 91 drives the ultrasonic device 92 to move upward, the shell 15 will move upward together, at this time, the second movable block 16 closes the second one-way valve 28 and opens it, and the gas in the inside of the shell 15 is extruded through the second movable block 16, so that the cold air first blows cold air to the welding joint of the first cloth 3 and the second cloth 4, and with the rising of the ultrasonic device 92, the air near the welding head 10 will be blown;

[0034] Through the lifting movement of the ultrasonic device 92, the shell 15 is further moved, the cold air in the inside of the shell 15 is extruded, and the first cloth 3, the second cloth 4 and the welding head 10 are cooled in sequence. Compared with the traditional device, the device cools the first cloth 3, the second cloth 4 and the welding head 10 after welding through cold air, which facilitates the rapid and firm welding of the first cloth 3 and the second cloth 4, and reduces the wear rate of the welding head 10.

[0035] As shown in FIGS. Figure 3 , 5 and 6, in one embodiment, a recess 20 is formed in the inside of the base 1, a clamping block 21 is movably installed in the inside of the recess 20, the clamping block 21 penetrates the base 1 upward and contacts the top of the first cloth 3, the second spring 22 is elastically connected between the bottom end of the recess 20 and the clamping block 21, the top of the base 1 is fixedly installed with a shell 23, a moving block 24 is movably installed in the inside of the shell 23, a horizontal rod 25 is movably installed in the inside of the shell 23, the left end of the horizontal rod 25 penetrates the moving block 24 and the shell 23 and extends into the inside of the horizontal rod 25, the right end of the horizontal rod 25 penetrates the shell 23, and the outer surface of the horizontal rod 25 movably sleeves the third spring 26 elastically connected between the right end of the moving block 24 and the right end of the inner cavity of the shell 23;

[0036] The working principle and beneficial effects of the above technical solution are that, the staff pulls the horizontal rod 25 to the right, so that the horizontal rod 25 drives the moving block 24 and moves to the right together and separates from the clamping block 21, at this time, the third spring 26 is in a elastic compression state, at this time, the second spring 22 will push the clamping block 21 upward under the action of the elastic force, so that the clamping block 21 moves upward, the first cloth 3 and the second cloth 4 are placed on the top of the welding table 2, the clamping block 21 is pressed downward, so that the clamping block 21 is in close contact with the top of the first cloth 3, the horizontal rod 25 is released, and due to the elastic recovery effect of the third spring 26, the horizontal rod 25 will be pushed to the left, so that the horizontal rod 25 is reset;

[0037] By pressing the clamp block 21 downward, the clamp block 21 is in close contact with the surface of the first cloth 3, and downward pressure is applied to the first cloth 3, so that the first cloth 3 and the second cloth 4 are fixed, and due to the design of the second spring 22, the lifting movement of the clamp block 21 is elastic, and the first cloth 3 and the second cloth 4 of different thicknesses can be fixed through the clamp block 21, preventing the first cloth 3 and the second cloth 4 from accidentally falling, and also applicable to the first cloth 3 and the second cloth 4 of different thicknesses, improving the practicability.

[0038] As shown in Figure 1 and 3 In one embodiment, the bottom end of the sliding rail 6 is fixedly installed with a limiting block 27, and the width of the limiting block 27 is greater than the width of the sliding rail 6.

[0039] The working principle and beneficial effects of the above technical solution are that due to the design of the limiting block 27, the lifting block 8 can be limited, preventing the lifting block 8 from moving downward to disengage from the sliding rail 6.

[0040] As shown in Figure 1 In one embodiment, the first cloth 3 is located on the top of the second cloth 4, and the widths of the first cloth 3 and the second cloth 4 are the same.

[0042] As shown in Figure 8 In one embodiment, the number of fixed blocks 14 is two, and the two fixed blocks 14 are located on both sides of the bottom end of the ultrasonic device 92.

[0043] The working principle and beneficial effects of the above technical solution are that due to the design of the fixed block 14, the two connecting rods 11 present a splayed shape, thereby facilitating the opposite movement of the two pulleys 12, and preventing the two connecting rods 11 from merging.

[0044] As shown in Figure 7 In one embodiment, the first spring 13 is located at the middle position of the longitudinal length between the two connecting rods 11, and the first spring 13 is located below the fixed block 14.

[0045] The working principle and beneficial effects of the above technical solution are that when the two connecting rods 11 move in opposite directions, the connecting rod 11 rotates at the connecting rod 11 and the hinge point of the ultrasonic device 92, at which time the first spring 13 will move upward relative to the fixed block 14, and when the ultrasonic device 92 moves upward, the connecting rod 11 is reset due to the elastic force of the first spring 13.

[0046] As Figure 6 shown in one embodiment, the outer surface of the second movable block 16 and the inner surface of the shell 15 are smooth, and the second movable block 16 is cylindrical with a certain thickness;

[0047] The working principle and beneficial effects of the above technical solution are that due to the design of the second movable block 16, the shell 15 is well limited, so that the shell 15 and the ultrasonic device 92 are more stable and smooth during the lifting movement.

[0048] Working principle and use process:

[0049] After the position of the lifting block 8 is adjusted by the worker, the position of the lifting block 8 is in a suitable position, the cylinder 91 is started, and the ultrasonic device 92 is driven downward by the operation of the cylinder 91, so that the welding head 10 contacts and presses the superimposed part of the first cloth 3 and the second cloth 4.

Under the extrusion of the welding head 10, the friction between the first cloth 3 and the second cloth 4 is large, and through vibration, high-frequency mutual friction between the first cloth 3 and the second cloth 4 is generated, so that high temperature is generated, and the first cloth 3 and the second cloth 4 are fused. Before the welding head 10 contacts the first cloth 3 and the second cloth 4, the pulley 12 will first contact the first cloth 3 and the second cloth 4, and when the ultrasonic device 92 continues to move downward, the two pulleys 12 will move in opposite directions at the bottom of the first cloth 3 and the second cloth 4, and at this time the first spring 13 is in a state of elastic tension under the tension;

[0050] Due to the operation of the cylinder 91, the ultrasonic device 92 and the shell 15 are driven downward together, at this time the vertical rod 17 and the second movable block 16 move downward relative to the shell 15, at this time the second one-way valve 28 is in a closed state, the first one-way valve 18 is opened, and the second movable block 16 fills the cold air into the interior of the shell 15, when it is finished, the cylinder 91 drives the ultrasonic device 92 to move upward, which drives the shell 15 to move upward together, at this time the second movable block 16 closes the second one-way valve 28 and opens the first one-way valve 18, and the second movable block 16 extrudes the gas in the interior of the shell 15, so that the cold air first blows cold wind to the welding part of the first cloth 3 and the second cloth 4, and with the rising of the ultrasonic device 92, the air near the welding head 10 is blown;

[0051] The worker pulls the crossbar 25 to the right, so that the crossbar 25 drives the moving block 24 and the clamping block 21 to move to the right together, at this time the third spring 26 is in the elastic compression state, at this time the second spring 22 will push the clamping block 21 upward under the action of the elastic force, so that the clamping block 21 moves upward, and the first cloth 3 and the second cloth 4 are placed on the top of the welding table 2, press the clamping block 21 downward, so that the clamping block 21 is in close contact with the top of the first cloth 3, release the crossbar 25, due to the elastic recovery effect of the third spring 26, the crossbar 25 will be pushed to the left, so that the crossbar 25 resets.
