Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric processing technology, and in particular to ultrasonic high-frequency vibration welding equipment for nonwoven fabrics. Background Technology

[0002] Nonwoven fabric is a fabric made of oriented or random fibers. In its production, it is often necessary to bond two pieces of nonwoven fabric together. This step usually involves using an ultrasonic welding machine to weld the joint between the two pieces of fabric.

[0003] When the non-woven fabric is placed on the top of the workbench, it will bend because the non-woven fabric is relatively soft. When welding, the bent parts will overlap under stress, which will easily cause wrinkles and reduce the welding effect. When manually flattening and fixing it, it needs to be fixed from both sides, and then it needs to be unfixed when removing the material. The operation is cumbersome and will affect the processing efficiency. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose an ultrasonic high-frequency vibration welding device for non-woven fabrics, so as to solve the problem that because the non-woven fabric is relatively soft, it will bend. When welding, the bent parts will overlap after being stressed, which will easily cause wrinkles and reduce the welding effect. When it is manually flattened and fixed, it needs to be fixed from both sides, and then the fixation needs to be released when the material is removed, which is cumbersome and affects the processing efficiency.

[0005] To achieve the above objectives, this utility model provides an ultrasonic high-frequency vibration welding device for non-woven fabrics, including a worktable, a movable rod fixedly connected to the upper end of the worktable, an ultrasonic generator provided at the front end of the movable rod, a welding head fixedly connected to the lower end of the ultrasonic generator, and a flattening mechanism provided on both sides of the upper end of the worktable.

[0006] The leveling mechanism includes L-shaped support rods fixedly connected to both sides of the upper end of the workbench. An electric rod is fixedly connected to the upper end of the L-shaped support rod, and an inclined block is fixedly connected to the output end of the electric rod. A first sliding groove is opened at the lower end of the inclined block, and a first slider is slidably connected inside the first sliding groove. A first spring is fixedly connected to the opposite side of each of the two first sliders. A vertical rod is fixedly connected to the lower end of the first slider, and a movable plate is provided at the lower end of the vertical rod.

[0007] Preferably, a horizontal bar is fixedly connected to the lower end of the vertical bar, and a second sliding groove is provided at the lower end of the horizontal bar. A second slider is slidably connected to both sides of the lower end of the second sliding groove. A second spring is fixedly connected between the two second sliders. A connecting rod is fixedly connected to the lower end of the second slider. The connecting rod is fixedly connected to a movable plate. Four movable plates are provided, two in a group, and connected to the corresponding connecting rods. Triangular blocks are fixedly connected to both sides of the upper end of the worktable, and limiting blocks are provided on both sides of the interior of the second sliding groove.

[0008] Preferably, a sliding rod is fixedly connected inside the first sliding groove, and the wall of the sliding rod is slidably connected to the inside of the first sliding block.

[0009] Preferably, the output end of the electric rod can only move up and down, and cannot rotate.

[0010] The beneficial effects of this utility model are:

[0011] By moving the inclined block downwards, the two moving plates move outwards simultaneously under the action of the first slider, thereby flattening the non-woven fabric. This prevents wrinkles from forming on the non-woven fabric during welding, thus improving the welding quality. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0020] like Figure 1-3 As shown, this utility model provides a non-woven fabric ultrasonic high-frequency vibration welding equipment, including a workbench 1, a movable rod 2 fixedly connected to the upper end of the workbench 1, an ultrasonic generator 3 provided at the front end of the movable rod 2, the ultrasonic generator 3 can generate high-frequency vibration, in the prior art, a welding head 4 fixedly connected to the lower end of the ultrasonic generator 3, the ultrasonic generator 3 drives the welding head 4 to vibrate, and a flattening mechanism is provided on both sides of the upper end of the workbench 1.

[0021] The leveling mechanism includes L-shaped support rods 5 fixedly connected to both sides of the upper end of the worktable 1, which are used to support the electric rod 6. The upper end of the L-shaped support rod 5 is fixedly connected to the electric rod 6, which can extend and retract. In the prior art, the output end of the electric rod 6 is fixedly connected to a wedge block 7, which drives the wedge block 7 to move up and down. The lower end of the wedge block 7 is provided with a first slide groove 12, and a first slider 11 is slidably connected inside the first slide groove 12. The first slider 11 moves inside the first slide groove 12. A first spring 14 is fixedly connected to the opposite side of the two first sliders 11, and the first spring 14 provides a certain supporting force to the first slider 11. The lower end of the first slider 11 is fixedly connected to a vertical rod 8, which moves synchronously with the vertical rod 8. The lower end of the vertical rod 8 is provided with a moving plate 19, which moves the vertical rod 8 and drives the moving plate 19 to move. The output end of the electric rod 6 can only move up and down and cannot rotate.

[0022] During operation, the non-woven fabric is placed on the upper part of the workbench 1. Then, both electric levers 6 work simultaneously to move the inclined block 7 downwards. As the inclined block 7 moves downwards, it causes the first slider 11 to move downwards. The first slider 11, through the vertical rod 8, causes the moving plate 19 to move downwards. The moving plate 19 moves downwards and contacts the non-woven fabric. At this time, the electric levers 6 continue to move the inclined block 7 downwards, while the moving plate 19 can no longer move downwards. This allows the first slider 11 to move inside the first slide groove 12. Because the first slide groove 12 is inclined, when the first slider 11 moves, it causes the moving plate 19 to move through the vertical rod 8. When the moving plate 19 moves, it pulls the non-woven fabric outwards. Force is applied, and the two moving plates 19 move simultaneously, thereby flattening the non-woven fabric. It should be noted that after the non-woven fabric is flattened, as the moving plates 19 continue to move, the non-woven fabric and the moving plates 19 will slide relative to each other. At this time, the ultrasonic generator 3 vibrates and moves to the position to be welded under the action of the moving rod 2. At this time, the welding head 4 contacts the non-woven fabric, so that the non-woven fabric is welded. In this way, during operation, by moving the inclined block 7 downward, under the action of the first slider 11, the two moving plates 19 move outward simultaneously, thereby flattening the non-woven fabric. This prevents the non-woven fabric from wrinkling when the welding head 4 is welding, thus improving the welding quality.

[0023] like Figure 2 and Figure 3 As shown, a horizontal bar 9 is fixedly connected to the lower end of the vertical bar 8. The vertical bar 8 drives the horizontal bar 9 to move. A second slide groove 16 is provided at the lower end of the horizontal bar 9. A second slider 17 is slidably connected to both sides of the lower end of the second slide groove 16. The second slider 17 slides inside the second slide groove 16. A second spring 15 is fixedly connected between the two second sliders 17. The two second sliders 17 are connected by the second spring 15. A connecting rod 18 is fixedly connected to the lower end of the second slider 17. The connecting rod 18 is fixedly connected to the moving plate 19. The movement of the connecting rod 18 drives the moving plate 19 to move. There are four moving plates 19, two in a group, connected to the corresponding connecting rod 18. Triangular blocks 10 are fixedly connected to both sides of the upper end of the worktable 1. Limiting blocks 20 are provided on both sides of the interior of the second slide groove 16 for resetting and limiting the two second sliders 17.

[0024] The vertical rod 8 moves downward, causing the horizontal rod 9 to move downward. When the vertical rod 8 moves horizontally, it causes the horizontal rod 9 to move. The movement of the horizontal rod 9 causes the two connecting rods 18 to move. When the two connecting rods 18 move horizontally, they come into contact with the triangular block 10. Under the action of the triangular block 10, the two connecting rods 18 move forward and backward respectively while moving horizontally. The movement of the connecting rods 18 causes the moving plate 19 to move, thereby flattening the nonwoven fabric both left and right, and front and back, further improving the flattening effect of the nonwoven fabric.

[0025] like Figure 3As shown, a slide rod 13 is fixedly connected inside the first slide groove 12. The wall of the slide rod 13 is slidably connected to the inside of the first slider 11, making the first slider 11 move more stably.

[0026] Working principle: During operation, the non-woven fabric is placed at the upper end of the worktable 1. Then, the two electric levers 6 work simultaneously to move the inclined block 7 downwards. As the inclined block 7 moves downwards, it causes the first slider 11 to move downwards. The first slider 11, through the vertical rod 8, causes the moving plate 19 to move downwards. The moving plate 19 moves downwards and contacts the non-woven fabric. At this time, the electric lever 6 continues to move the inclined block 7 downwards, while the moving plate 19 can no longer move downwards. This allows the first slider 11 to move inside the first slide groove 12. Because the first slide groove 12 is inclined, when the first slider 11 moves, it causes the moving plate 19 to move through the vertical rod 8. When the moving plate 19 moves, it exerts an outward force on the non-woven fabric. Pulling force causes the two moving plates 19 to move simultaneously, thereby flattening the non-woven fabric. It should be noted that after the non-woven fabric is flattened, as the moving plates 19 continue to move, the non-woven fabric and the moving plates 19 will slide relative to each other. At this time, the ultrasonic generator 3 vibrates and moves to the position to be welded under the action of the moving rod 2. At this time, the welding head 4 contacts the non-woven fabric, so that the non-woven fabric is welded. In this way, during operation, by moving the inclined block 7 downward, under the action of the first slider 11, the two moving plates 19 move outward simultaneously, thereby flattening the non-woven fabric. This prevents the non-woven fabric from wrinkling when the welding head 4 is welding, thus improving the welding quality.

[0027] Furthermore, the vertical rod 8 moves downward, causing the horizontal rod 9 to move downward. When the vertical rod 8 moves horizontally, it causes the horizontal rod 9 to move. The movement of the horizontal rod 9 causes the two connecting rods 18 to move. When the two connecting rods 18 move horizontally, they come into contact with the triangular block 10. Under the action of the triangular block 10, the two connecting rods 18 move forward and backward respectively while moving horizontally. The movement of the connecting rods 18 causes the moving plate 19 to move, thereby flattening the nonwoven fabric both left and right and front and back, further improving the flattening effect of the nonwoven fabric.
