[0002] Sealing machines are one of the most commonly used packaging equipment and are widely used in the fields of food, cosmetics, clothing, shoes and leather, chemicals, electrical appliances, medicine, tea, dairy products, beverages, etc. Current sealing machines all use heat sealing technology to press and melt the mouth of the packaging bag. Hot melting requires a process of heating and cooling, which results in a single sealing of the packaging bag. It takes time, which has a greater negative impact on production capacity when dealing with large batches of packaging production. In addition, sealing machines are often used in continuous automated production processes.

[0043] In one embodiment of the present invention: Please refer to Figure 3-6 , a pressing cylinder 105 is provided at one end of the linear rail push cylinder group 103, a movable mounting frame 104 and the pressing cylinder 105 are slidably connected on the side of the linear rail push cylinder group 103, the top ends of the pressing end concave plate 107 are respectively connected to the fixed mounting frame 106, the top ends of the ultrasonic convex plate 108 are respectively fixed to the bottom of the movable mounting frame 104, and the movable mounting frame 104 is connected to the pressing cylinder 105; an adjusting block 110 is provided at the position where the movable mounting frame 104 is connected to the linear rail push cylinder group 103, which is used to adjust the movable mounting frame 104 The limit movement distance, the installation positions of the movable mounting frame 104 and the fixed mounting frame 106 can be interchanged, that is, the concave plate 107 at the pressing end is connected to the bottom of the movable mounting frame 104 and the bottom of the fixed mounting frame 106 is connected to the ultrasonic convex plate 108. It is only necessary to keep one end of the movable mounting frame 104 and the pressing cylinder 105 connected to each other, and the other fixed mounting frame 106 is installed on the linear rail push cylinder group 103 in a point-fixed manner. The feeding mode, distance and extrusion time of the pressing cylinder 105 are set by the program, which is the same as or multiples of the rotation angle time stroke of the rotating clamping component 2.

[0044] In another embodiment of the present invention: Please refer to Figure 2 , Figure 3 The upper part of the pressing end concave plate 107 is fixedly connected to the linear rail push cylinder group 103, and a longitudinally installed sliding rod is provided inside the pressing end concave plate 107, and a top connection block 117 is connected to the sliding rod, and one side of the top connection block 117 is sleeved with the sliding rod, and the movable group 113 is fixed inside the concave area of ​​the pressing end concave plate 107 and the active end is connected to the top connection block 117;

[0045] The active end of the ultrasonic generator 101 is connected to the side of the ultrasonic convex plate 108 away from the concave plate 107 at the pressing end, and the pressing gap is formed between the top connection block 117 and the ultrasonic convex plate 108;

[0046] The cooling assembly 112 acts on the peripheral side of the top contact block 117;

[0047] The movable group 113 includes two vibrators 120 fixed to the top of the concave surface of the pressed end concave plate 107, two vibration rods 121 are connected to the bottom of the two vibrators 120, and two movable piles 118 are provided on the top of the top connection block 117. Two connecting ports 119 are rotatably connected to the movable piles 118 respectively, and the top of the connecting port 119 is connected to the bottom of the vibration rod 121 to transmit vibration;

[0048] A protrusion 122 is provided on the top of the top connection block 117, an electric sleeve pile 123 is provided on one side of the protrusion 122, and a longitudinal sleeve rod 124 is provided on the other side of the protrusion 122. The longitudinal sleeve rod 124 is sleeved on the sliding rod, and one end of the longitudinal sleeve rod 124 is a column with a matching groove and is sleeved with the driving end of the electric sleeve pile 123.

[0049] During the action of the movable group 113, power is generated by the vibrator 120, and the vibration is transmitted by the vibrator 120. At the same time, the lateral deflection is adjusted by the movable pile 118. At this time, a variety of sealing methods can be produced, in which the two sides of the top block 117 are in a fixed relationship with the linear rail push cylinder group 103 in the horizontal direction and in a movable relationship in the vertical direction. One side of the top block 117 is in a close relationship with the cooling ring belt 116, and the cooling ring belt 116 is in a direct contact relationship with the packaging bag. The top block 117 can be provided with horizontal or vertical micro grooves or micro protrusions, combined with multiple top pressures of the pressing cylinder 105 and ultrasonic generation. Due to the ultrasonic effect of the device 101, each contact point between the top contact block 117 and the surface of the packaging bag changes. The source of the change is that the vibration on one side causes the micro-groove or micro-convex to shift in a small range. The shifted contact point or surface is attached to the established pressing surface layer temporarily pressed by the pressing cylinder 105 on the upper side, forming multiple small-scale staggered pressing surfaces (which can be referred to as stacked pressing). In addition, each recovery takes away part of the heat on the cooling ring belt 116, so that the established pressing surface layer of the upper layer can undergo a cold shrinkage and temperature change condensation, so that when the ultrasonic hot pressing is performed again, it has more stable properties without adhesion and coking.

[0050] In another embodiment of the present invention: Please refer to Figure 2-6 The pressing side of the top connection block 117 can be a plane and a convex or concave arc surface facing inward or outward, and the pressing side of the ultrasonic convex plate 108 can be a plane and a convex or concave arc surface facing inward or outward. The ultrasonic convex plate 108 is in a planar fitting state when matched with the top connection block 117; when the top connection block 117 and the ultrasonic convex plate 108 are pressed in an arc surface, the center of the arc surface is always on the same axis as the center of the flow turntable 201, and the plate surface top connection block 117 and the ultrasonic convex plate 108 are close to each other. When the surface is an arc surface, it can adapt to the margin of the rotating clamping component 2 without restricting the bending of the lower clamping part, that is, the two margin grippers 202 on the side of the rotating clamping component 2 jointly grasp the two side ends of a packaging bag. At this time, if the margin grippers 202 are installed to point to the center of the circle, the two ends of the packaging bag will be pulled toward the outside of both sides to be in a taut state. At this time, when the upper end contacts the pressing gap, there will be an unmatched blocking problem, which may cause the upper part of the sealing of the packaging bag to bend inside the gap, thereby resulting in an inability to accurately seal.

[0051] In another embodiment of the present invention: Please refer to Figure 3-6, two matching grooves 111 are provided at one end of the bottom of the pressed end concave plate 107 close to the ultrasonic convex plate 108, the cooling assembly 112 includes two freezing tubes 114 with the same axial position as the two matching grooves 111, and the bottom of the freezing tubes 114 is provided with two lateral openings 115 facing similarly; the outsides of the two freezing tubes 114 are jointly sleeved with a cooling belt 116, and the rotation axes at both ends of the cooling belt 116 are the same as those of the freezing tubes 114; the cooling belt 116 is a tough thermal conductive material; both sides of the ultrasonic convex plate 108 are provided with introduction extrusion blocks 125, and the end of the introduction extrusion block 125 in contact with the packaging bag is an oblique cut, and the oblique cut is inclined from bottom to top and has a turning chamfer; the gripper of the margin gripper 202 The end is a movable claw seat 203, which can rotate the clamping angle; the side of the pressing end concave plate 107 is provided with a lateral guide plate 126; when the upper sealing area of ​​the packaging bag enters the narrow pressing surface formed by the pressing end concave plate 107 and the ultrasonic convex plate 108, if the two ends are in a state of being pulled by the two movable claw seats 203, the upper lateral guide plate 126 will guide the excess part in advance to prevent it from folding laterally, and at the same time, the packaging bag will be close to the cooling belt 116 and drive the cooling belt 116 to move in a conveyor belt manner, and the cooling belt 116 does not have a moving stroke up and down, or when the movable claw seat 203 is adjusted so that there is no pulling effect on both sides of the packaging bag, the introduction extrusion block 125 on the other side drives the upper end of the open packaging bag to be squeezed into the size of the pressing gap in advance and expel some of the internal gas in a bottom-up manner.
