Description

Technical Field

[0001] This utility model relates to the field of hygiene products and equipment, specifically to an ultrasonic welding device with cleaning function. Background Technology

[0002] In the production of hygiene products such as diapers or sanitary napkins, it is often necessary to connect non-woven fabrics, waterproof membranes, or front and back waistbands. To make them safer, healthier, and more environmentally friendly, ultrasonic welding is now used in some parts of the production process to replace traditional glue bonding. Ultrasonic welding technology uses ultrasonic vibrations, transmitted through a welding head to the bonding surfaces of the functional raw materials. Frictional heat causes the materials to melt and recombine, forming a weld. When welding fibrous materials, especially non-woven fabrics, some lint or short fibers can easily adhere to the welding head of the ultrasonic welding machine. If not cleaned in time, this can affect the subsequent welding strength or even cause incomplete welds, thus affecting product quality. Therefore, there is a need for an ultrasonic welding device with a cleaning function that can automatically clean the residue adhering to the welding head, preventing residue from affecting the welding strength and ensuring product quality. This case arises from this need. Utility Model Content

[0003] To overcome the shortcomings of the prior art, this utility model discloses an ultrasonic welding device with a cleaning function, including an ultrasonic welding machine, a support frame assembly, a rotating assembly, and a cleaning assembly. This utility model symmetrically arranges two sets of ultrasonic welding machines and utilizes the rotating assembly to intermittently rotate and drive the two sets of ultrasonic welding machines to alternate left and right positions. When one set of ultrasonic welding machines is working, the welding head of the other set of ultrasonic welding machines can be automatically cleaned by several high-speed rotating electric brushes driven by the rotating drum of the cleaning assembly. This can prevent residues adhering to the welding head from affecting the welding strength and ensure product quality.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An ultrasonic welding device with a cleaning function includes two sets of ultrasonic welding machines symmetrically arranged. The device further includes a support frame assembly, a rotating assembly, and a cleaning assembly. The rotating assembly has a rotating shaft and a T-shaped connector fixed above the rotating shaft. The rotating shaft is vertically positioned and rotatably connected to the support frame assembly. The two sets of ultrasonic welding machines are positioned above the support frame assembly and symmetrically fixed to the left and right sides of the connector of the rotating assembly. The rotating assembly can rotate intermittently and drive the two sets of ultrasonic welding machines to alternate positions. The cleaning assembly is fixed to the support frame assembly and positioned below one set of ultrasonic welding machines. The cleaning assembly has several electric brushes, which are dispersed and fixed on a rotatable cylinder for automatically cleaning the welding heads of the ultrasonic welding machines that have alternately moved above it.

[0005] The support frame assembly includes a bracket, a support base, and an anvil. The support base is a square base with a stepped circular hole running vertically through its center. The bracket has an upper panel and a lower support plate. The support base is placed on the bracket and fixedly connected to the upper panel and lower support plate of the bracket. The anvil is fixedly connected to the upper plate of the bracket and placed below the welding head of another ultrasonic welding machine, which is symmetrical to the ultrasonic welding machine above the cleaning assembly.

[0006] The rotating assembly is also equipped with a rotary cylinder. The cylinder rod of the rotary cylinder can rotate intermittently, and the angle of each rotation is 180°. The rotating shaft is a stepped circular shaft.

The lower end of the rotating shaft is connected to the cylinder rod of the rotary cylinder. The rotary cylinder can drive the rotating shaft and the connecting parts above the rotating shaft to rotate intermittently. The cylinder body of the rotary cylinder is connected to the bracket of the support frame assembly.

[0007] The cleaning assembly also includes a rotating cylinder assembly, which includes a rotating cylinder, ribs, a spindle, and a motor. The rotating cylinder is a circular cylinder with several ribs evenly distributed and fixed at both ends inside the cylinder. The spindle is placed at the center of the horizontally placed rotating cylinder and is fixed to several ribs inside the rotating cylinder. Both ends of the spindle extend outward, and the output shaft of the motor is connected to one end of the spindle.

[0008] The outer wall of the rotating drum is provided with a number of mounting holes evenly distributed along the circumference, and a number of electric brushes are installed on the mounting holes of the rotating drum accordingly.

[0009] The electric brush is equipped with a micro motor and a brush head connected to the micro motor. The brush head includes a bowl-shaped base and bristles arranged in a radiating pattern on the bowl-shaped base. Preferably, the bristles of the electric brush are flexible steel wires.

[0010] The cleaning assembly also includes a housing, which is a square cavity formed by a bottom wall and four surrounding walls.

The suction port of the dust pump is connected to the waste discharge port, and the discharge port of the dust pump is connected to an external dust collection device.

[0012] The ultrasonic welding machine is an ultrasonic welding machine that can perform ultrasonic welding on the original sheets of sanitary products.

[0013] As described above, the beneficial effects of the ultrasonic welding device with cleaning function provided by this utility model are as follows: By symmetrically arranging two sets of ultrasonic welding machines and utilizing a rotating component that can rotate intermittently and drive the two sets of ultrasonic welding machines to alternate left and right positions, while one set of ultrasonic welding machines is working, the welding head of the other set of ultrasonic welding machines can be automatically cleaned by several high-speed rotating electric brushes driven by the rotating drum of the cleaning component. This avoids residues adhering to the welding head, which affects the welding strength and ensures product quality; it also avoids the need to stop the machine for manual cleaning of the welding head during single-machine production, thus reducing work efficiency. This utility model has a reasonable design, simple structure, low cost, and is easy to promote. Attached Figure Description

The anvil 23 is fixedly connected to the upper panel of the bracket 21 and placed below the welding head of another ultrasonic welding machine 1. This ultrasonic welding machine 1 is symmetrical to the ultrasonic welding machine 1 above the cleaning assembly 4.

[0019] like Figures 1 to 4 As shown, the rotating assembly 3 of this utility model includes a rotating shaft 31, a connecting member 32, and a rotating cylinder 33. The connecting member 32 is T-shaped and is fixed above the rotating shaft 31. The rotating shaft 31 is a stepped circular shaft. The rotating shaft 31 is upright and passes through the circular hole in the center of the support seat 22 of the support frame assembly 2 and is rotatably connected to the support seat 22 by a radial bearing and a thrust bearing. The lower end of the rotating shaft 31 is connected to the cylinder rod of the rotating cylinder 33. The cylinder rod of the rotating cylinder 33 can rotate intermittently, and the angle of each rotation is 180°. The rotating cylinder 33 can drive the rotating shaft 31 and the connecting member 32 above the rotating shaft 31 to rotate intermittently. The cylinder body of the rotating cylinder 33 is connected to the bracket 21 of the support frame assembly 2.

[0020] like Figures 1 to 3 , Figures 5 to 8As shown, the cleaning component 4 of this utility model includes a housing 41, an electric brush 42, a rotating cylinder assembly 43, a waste outlet 44, and a dust pump 45. The housing 41 is a square cavity formed by a bottom wall and four surrounding walls, and a funnel-shaped baffle is provided at the lower part of its inner cavity. The electric brush 42 is equipped with a micro motor and a brush head connected to the micro motor. The brush head includes a bowl-shaped base and bristles arranged in a radiating pattern on the bowl-shaped base. In this embodiment, the bristles of the electric brush 42 are flexible steel wires, and the electric brush 42 is a known technology. The rotating cylinder assembly 43 includes a rotating cylinder 431, ribs 432, a spindle 433, and a motor 434. The rotating cylinder 431 is a circular cylinder with several ribs 432 evenly distributed and fixed to both ends of its interior. The spindle 433 is placed at the center of the horizontally positioned rotating cylinder 431 and is fixed to the several ribs 432 inside the rotating cylinder 431. Both ends of the spindle 433 extend outward. The output shaft of the motor 434 is connected to one end of the spindle 433. Several mounting holes are evenly distributed along the circumference of the middle of the outer wall of the rotating cylinder 431. Several electric brushes 42 are provided, and the electric brushes 42 are correspondingly installed on the several mounting holes of the rotating cylinder 431. The rotating cylinder assembly 43 is placed on the upper part of the housing 41. Its spindle 433 has its two ends rotatably connected to the two opposite side walls of the housing 41 by bearing seats. The housing 41 is fixed to the lower support plate of the bracket 21 and to the support base 22. The motor 434 is fixed to the housing 41.

[0021] When this device is in use, the ultrasonic welding machine 1 placed above the anvil 23 is welding normally, while the ultrasonic welding machine 1 placed above the cleaning component 4 is in a stopped state. At this time, the motor 434 of several electric brushes 42 and the rotating cylinder assembly 43 of the cleaning component 4 is started, driving the rotating cylinder 431 to rotate slowly and drive the several electric brushes 42, which are rotating at high speed, to rotate together. The electric brushes 42 are used to clean the welding head of the ultrasonic welding machine 1 placed above it in turn. When the two ultrasonic welding machines 1 need to be switched left and right to clean the welding head of the other ultrasonic welding machine 1, the rotating cylinder 33 of the rotating component 3 is started, driving the rotating shaft 31 and the connecting part 32 to rotate 180° and then locking it using the pneumatically controlled stop function of the rotating cylinder 33. The above cleaning action is then repeated. The residue can be sucked out by the dust pump 45 for centralized treatment.

[0022] This invention symmetrically arranges two sets of ultrasonic welding machines 1 and utilizes a rotating component 3 that can rotate intermittently and drive the two sets of ultrasonic welding machines 1 to alternate positions. When one set of ultrasonic welding machines 1 is working, the welding head of the other set of ultrasonic welding machines 1 can be automatically cleaned by several high-speed rotating electric brushes 42 driven by the rotating drum 431 of the cleaning component 4. This avoids residues adhering to the welding head from affecting the welding strength and ensures product quality.

[0023] The above is only one specific embodiment of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantial modifications made to the present utility model using this concept shall be deemed as an infringement of the protection scope of the present utility model.
