[0025] As a further embodiment of the present application, a movable support base 6 is fixedly installed on the top conveyor belt 3, and a height adjustment base 7 is fixedly installed between adjacent movable support bases 6, wherein a loading mechanism 2 is provided on the height adjustment base 7, and a top adsorption port 8 is provided at the output end of the loading mechanism 2, and the top adsorption port 8 is utilized to realize the adsorption function of the heavy bag 4, and the top conveyor belt 3 is utilized to drive the movable support base 6 to move, thereby driving the height adjustment base 7, so that the heavy bag 4 can be driven to move.
[0026] Furthermore, the feeding mechanism 2 includes a first hinge rod 22 and a second hinge rod 27, wherein the first hinge rod 22 and the second hinge rod 27 are respectively slidably hinged on the height adjustment base 7, and at the same time, the middle position of the first hinge rod 22 and the second hinge rod 27 is rotatably connected, and an articulated support base 26 is rotatably installed at one end of the first hinge rod 22 and the second hinge rod 27 away from the height adjustment base 7, wherein the articulated support base 26 is slidably installed on the bottom power base 23, and a bidirectional screw is provided inside the bottom power base 23, and the bidirectional screw is respectively threadedly connected to the articulated support base 26, and the power motor When the bidirectional screw is driven to rotate, the adjacent hinged support bases 26 can move toward or away from each other, thereby controlling the angle between the first hinged rod 22 and the second hinged rod 27, and facilitating the control of the distance between the bottom power base 23 and the height adjustment base 7, so that the height of the height adjustment top plate 21 fixedly mounted on the bottom power base 23 can be adjusted.

[0027] Furthermore, the bonding mechanism 5 includes a bottom support plate 51, wherein the bottom support plate 51 is evenly provided with bottom adsorption ports 52. When in use, the bottom adsorption ports 52 can be used to adsorb and fix the bottom of the heavy bag 4 to prevent it from moving. At the same time, a sliding fitting groove 56 is provided on the bottom support plate 51. The sliding fitting groove 56 is used to move the bottom support plate 51 to the bonding power equipment, and use the bonding power equipment to ultrasonically bond the heavy bag 4 and the easy-to-peel film.
[0028] Specifically, a side slider is fixed to the side of the bottom support plate 51, and the side slider is slidably connected to the side movable base 108. An internal slide groove 109 is provided on the side movable base 108, and an internal screw 1010 is provided inside the internal slide groove 109 to be rotated by a motor, wherein the side slider and the internal screw 1010 are threadedly connected.

[0029] Furthermore, a sliding fitting plate 54 is fixed on the frame, and the sliding fitting plate 54 and the sliding fitting groove 56 are slidably fitted, and a processing adsorption port 55 for adsorbing and fixing the weight bag 4 is fixed on the sliding fitting plate 54. At the same time, a second ultrasonic welder 53 for bonding the weight bag 4 and the easy-to-remove film is also fixed on the sliding fitting plate 54.

[0030] Furthermore, a side support base 24 is fixedly installed on the side of the height adjustment top plate 21, wherein a first ultrasonic welding device 25 for cooperating with the heavy bag 4 and the top of the easy-to-peel film is fixed at the bottom of the side support base 24, and is used to ultrasonically weld the top of the heavy bag 4 and the easy-to-peel film, thereby achieving accurate fitting of the heavy bag 4 and the easy-to-peel film.
[0031] Furthermore, the adjustment mechanism 1 includes a triangular adjustment plate 101, that is, a side fixing plate 107 is fixed to the side of the side movable base 108, and a second hydraulic cylinder 106 is fixedly mounted on the side fixing plate 107.

When in use, the activation of the second hydraulic cylinder 106 controls the longitudinal movement of the adjustment base 104, and the second hydraulic cylinder 106 is used to move the triangular adjustment plate 101, so that the glue spraying outlets 102 can act on the heavy bag 4 to adjust the angle of the heavy bag 4.
[0032] When the present invention is in use, the top conveyor belt 3 is first used to move the feeding mechanism 2 to the feeding station, and the output end of the feeding mechanism 2 is used to move downward until the heavy bag 4 is adsorbed, and then the heavy bag 4 is adsorbed onto the bonding mechanism 5. At this time, the shape of the heavy bag 4 is the first shape 9, that is, the heavy bag 4 is in a tensioned state, which can ensure that the heavy bag 4 will not be deformed during adsorption. Then the feeding mechanism 2 releases the restriction on the heavy bag 4 and moves with the bottom support plate 51 until the bottom support plate 51 moves to the position of the second ultrasonic welding device 53. Then the heavy bag 4 is located in the bonding mechanism 5. When loading, the heavy bag 4 is adsorbed by controlling the adsorption port that generates the adsorption function on the fitting mechanism 5 and the adsorption port that generates the adsorption function on the feeding mechanism 2, until the state of the heavy bag 4 is transferred to the intermediate form 10, and then the adjustment mechanism 1 is started to adjust the state of the heavy bag 4 to the composite form 11.

At the same time, after the ultrasonic processing is completed, the glue liquid can also cool down in a natural state to ensure that the folded and fitted parts thereof avoid the problem of breakage caused by large pulling and ensure the stability of the folded parts. In this process, the heavy bag 4 is adjusted to the composite shape 11. In this process, the holding part of the heavy bag 4 is adjusted to the composite shape 11, which is convenient for welding the heavy bag 4 and the easy-to-peel film, avoiding the problem of easy collapse and affecting the holding capacity caused by welding in a straight line. When the fitting mechanism 5 is in use, that is, when the sliding fitting plate 54 is moved to the sliding fitting groove 56, the processing adsorption port 55 is used to achieve adsorption and fixation of the heavy bag 4, and then the second ultrasonic welding device 53 is used to achieve the fitting connection between the heavy bag 4 and the easy-to-peel film. After this process, the first ultrasonic welding device 25 is used to weld the heavy bag 4 and the easy-to-peel film again to ensure that the heavy bag 4 and the easy-to-peel film are fully connected.
