Description

Technical Field

[0001] The invention relates to the field of rock sealing packaging machines, in particular to an ultrasonic sealing packaging machine. Background Art

[0002] Ultrasonic sealing valve is a kind of ultrasonic plastic welding machine. It uses ultrasonic concentrator to act on the sealing part of packaging container to seal the packaging container. The ultrasonic energy is transmitted to the welding area through the upper weldment. Since the welding area, i.e. the interface between the two welds, has large acoustic resistance, local high temperature will be generated. Due to the poor thermal conductivity of plastic, it cannot be dissipated in time and gathers in the welding area, causing the contact surface of the two plastics to melt rapidly. After a certain pressure is applied, it is fused into one. When the ultrasonic wave stops acting, the pressure is allowed to continue for a few seconds to solidify and form, thus forming a strong molecular chain to achieve the purpose of welding. The welding strength can be close to the strength of the raw materials, which is suitable for the packaging of plastic containers.

[0003] At present, most of the existing pocket packaging machines lack a height adjustment mechanism, which makes it difficult for the equipment to seal and package pockets of different height specifications. Most of them also lack a protective mechanism, which easily causes the packaging bags to fall, and their applicability is poor. Summary of the invention

[0004] In view of the deficiencies of the prior art, the present invention provides an ultrasonic sealing packaging machine to overcome the deficiencies of the prior art.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an ultrasonic sealing packaging machine, comprising a bottom plate, a fixed plate connected to the upper end of the bottom plate, a material tank installed on the side wall of one side of the fixed plate, a movable plate slidably connected to the fixed plate, a lifting component for adjusting the height of the movable plate installed on the material tank, a moving groove is provided on the side wall of one side of the movable plate, a bidirectional screw rod is rotatably connected in the moving groove, a rotating component for driving the bidirectional screw rod to rotate is installed on the movable plate, two moving blocks are symmetrically threadedly connected on the rod wall of the bidirectional screw rod, the moving block is slidably connected in the moving groove, and the moving block matches the moving groove, a clamping plate is installed at one end of the moving block, an ultrasonic mechanism is installed on the upper end of the clamping plate, a transverse plate is arranged below the movable plate, a connecting component for adjusting the height of the transverse plate is installed on the movable plate, a placement plate is arranged above the transverse plate, a supporting component for supporting the placement plate is installed on the transverse plate, two driving plates are symmetrically slidably connected to the upper end of the transverse plate about the placement plate, an auxiliary plate is connected to the upper end of the driving plate, and a driving rod is hinged between the driving plate and the placement plate.

[0006] By adopting the above technical solution, when in use, the movable plate is moved in the vertical direction through the lifting component, and the movement of the movable plate will drive the horizontal plate and the placement plate to move in the vertical direction. When the movable plate moves to the specified position, the horizontal plate can be moved in the vertical direction through the connecting component to move the horizontal plate to the specified position. At this time, the packaging bag is placed on the placement plate, the material tank is opened, and the material is injected into the packaging bag. As the material enters the packaging bag, the weight of the packaging bag will increase, and the packaging bag will move downward through the supporting component. The movement of the packaging bag will apply a force to the driving plate through the driving rod. The driving plate will move on the horizontal plate under the force, and the movement of the driving plate will drive the auxiliary plate to move. When the packaging bag moves, the auxiliary plate will be close to the packaging bag to limit and block the packaging bag to prevent the packaging bag from falling. When the packaging bag needs to be sealed, the ultrasonic mechanism is started, and the bidirectional screw is rotated by rotating the assembly. The rotation of the bidirectional screw will apply a force to the two moving blocks through the action of the thread. The moving blocks will drive the splint to move under the force, and the movement of the splint will drive the ultrasonic mechanism to move. When the ultrasonic mechanism moves to the bag opening of the packaging bag, the ultrasonic mechanism will seal the packaging bag. The height of the packaging bag can be adjusted through the above structure, so that the device can seal packaging bags of different specifications. The operation is simple and convenient, thereby improving the applicability of the device.

[0016] By adopting the above technical solution, when the placement plate moves downward, the placement plate will drive the support rod to move in the support tube, the movement of the support rod will squeeze the spring, and the spring will be deformed due to the squeezing. When the packaging bag on the placement plate is removed, the spring will reset, and the spring will drive the support rod and the placement plate to reset.
