[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] As mentioned in the background section, existing technologies suffer from laborious and time-consuming pressing processes, and the aluminum-plastic pulleys are difficult to transfer after pressing and welding. This invention proposes a highly efficient ultrasonic welding device for pressing aluminum-plastic pulleys. Example

[0031] Reference Figures 1 to 6 An ultrasonic welding device for pressing aluminum-plastic belt pulleys includes an ultrasonic welding device body 1, a fixing frame 2, an aluminum-plastic belt pulley 6, a reinforcing ring 14, and a transfer assembly.

[0032] Support legs 3 are provided around the bottom of the fixed frame 2;

[0033] The fixed frame 2 is provided with a fixing component 1 for fixing the aluminum-plastic pulley 6;

[0034] The fixed frame 2 is provided with a fixing component 2 for fixing the reinforcing ring 14;

[0035] A drive component is provided on the fixed frame 2, and the drive component is connected to both the fixed component 2 and the pressing component.

[0036] The fixing component includes two sets of hydraulic telescopic rods 4 with identical structures. The two sets of hydraulic telescopic rods 4 are respectively arranged laterally on the inner walls of both sides of the fixing frame 2. The two sets of hydraulic telescopic rods 4 are each provided with a fixing seat 5 on the opposite side. The longitudinal section of the fixing seat 5 is L-shaped. The two sides and the bottom sides of the aluminum-plastic pulley 6 are in contact with the two sets of fixing seats 5 respectively, so that the aluminum-plastic pulley 6 can be placed on the fixing seat 5 first, and then the fixing seat 5 is moved by the hydraulic telescopic rods 4 to fix the aluminum-plastic pulley 6.

[0037] The second fixing component includes a support base 8, with horizontal bars 9 extending through both sides of the support base 8. Clamping blocks 10 are provided on opposite sides of the two sets of horizontal bars 9, and the two sides of the reinforcing ring 14 are in contact with the two sets of clamping blocks 10 respectively. A return spring 11 connected to the support base 8 is provided on the side of the two sets of clamping blocks 10 that is far apart from each other. The spring force of the return spring 11 is used to fix the reinforcing ring 14 so that the reinforcing ring 14 can be moved above the center hole of the aluminum-plastic pulley 6. The front side of the support base 8 is connected to the electric telescopic rod 12, and the electric telescopic rod 12 is mounted on the connecting frame 13. The electric telescopic rod 12 is used to drive the clamping blocks 10 to move in the front-back direction to avoid the clamping blocks 10 being obstructed by the center hole of the aluminum-plastic pulley 6 when moving to the left.

[0038] The top front and rear sides of the fixed frame 2 are provided with sliding grooves 15.

[0039] The pressing assembly includes a mounting frame 7, on which a cylinder 20 is mounted, and on which a pressing ring 21 is mounted. The pressing ring 21 is moved downward by the cylinder 20, so that the reinforcing ring 14 between the clamping blocks 10 is pressed into the center hole of the aluminum-plastic pulley 6. The mounting frame 7 is slidably connected to the rear slide groove 15, and the connecting frame 13 is slidably connected to the front slide groove 15.

[0040] The drive assembly includes two sets of identical rotating shafts 17, each set of rotating shafts 17 is equipped with a lead screw 16 and a pulley 18. The threads on the two lead screws 16 are turned in opposite directions. The two lead screws 16 are rotatably mounted on the two sliding grooves 15 via bearings. The mounting bracket 7 is screwed onto the rear lead screw 16, and the connecting bracket 13 is screwed onto the front lead screw 16, so that the connecting bracket 13 and the mounting bracket 7 move in opposite directions. A belt is connected between the two pulleys 18. A motor 19 is mounted on the fixed frame 2, and the output shaft of the motor 19 is connected to the front rotating shaft 17. The motor 19 drives the rotating shaft 17 to rotate, so that the pulley 18 can drive the two lead screws 16 to rotate synchronously.

[0041] The transfer assembly includes a roller conveyor 22 located below the fixed frame 2, which is used to transport the welded aluminum-plastic pulley 6 to the next process.

[0042] The roller conveyor 22 is provided with a through groove opposite to the aluminum-plastic pulley 6.

[0043] A vertical toothed rod 23 is attached to the bottom of the aluminum-plastic pulley 6 and passes through a through groove, allowing the vertical toothed rod 23 to move through the groove. The vertical toothed rod 23 is located between two sets of fixed seats 5 and does not affect the clamping of the aluminum-plastic pulley 6 by the fixed seats 5. The vertical toothed rod 23 is slidably connected to the guide rail 24, which guides the vertical toothed rod 23. A gear 25 is meshed on the right side of the vertical toothed rod 23 and is mounted on the support shaft 26. The rotation of the support shaft 26 causes the gear 25 to drive the vertical toothed rod 23 to rise and fall. The support shaft 26 is rotatably mounted on the bearing seat 27. The bottoms of the bearing seat 27, the guide rail 24, and the support leg 3 are flush. A rotating component is provided at the front end of the support shaft 26. Example

[0044] Reference Figure 1 and Figure 6 The rotating assembly includes a second gear 28 disposed at the front end of the support shaft 26. The top of the second gear 28 is meshed with a transverse toothed rod 29. The top of the transverse toothed rod 29 is connected to a connecting rod 30, and the connecting rod 30 is connected to the connecting frame 13. When the connecting frame 13 moves laterally, the connecting rod 30 drives the transverse toothed rod 29 to move laterally, so that the second gear 28 can drive the support shaft 26 to rotate, so as to help the welded aluminum-plastic pulley 6 to be transferred when the connecting frame 13 moves.

[0045] The rest of the structure is the same as in Example 1.

[0046] Usage: Place the aluminum-plastic pulley 6 with the side requiring the reinforcing ring 14 facing upwards. Then, place the aluminum-plastic pulley 6 on the two side fixing seats 5. Move the fixing seats 5 to the opposite side using the hydraulic telescopic rod 4 to fix the aluminum-plastic pulley 6. Next, pull the crossbar 9 to both sides, causing the clamping block 10 to compress the return spring 11, allowing the reinforcing ring 14 to be placed between the two clamping blocks 10. Release the crossbar 9, and the reinforcing ring 14 will be fixed by the elastic force of the return spring 11. After step 14, the motor 19 drives the rotating shaft 17 to work, causing the lead screws 16 on both sides to move the connecting frame 13 and the mounting frame 7 laterally. This causes the connecting frame 13 to move to the left and the mounting frame 7 to move to the right. Then, the electric telescopic rod 12 drives the support base 8 to move backward, so that the reinforcing ring 14 is exactly above the center hole of the aluminum-plastic pulley 6. At this time, the cylinder 20 drives the pressing ring 21 to move downward, so that the reinforcing ring 14 is pressed into the center hole of the aluminum-plastic pulley 6 under the guidance of the clamping block 10. After pressing, both the connecting frame 13 and the mounting frame 7 are reset. The reinforcing ring 14 can then be welded to the center hole of the aluminum-plastic pulley 6 using an ultrasonic welding device. After welding, the hydraulic telescopic rod 4 drives the two fixed seats 5 to move away from each other, thus canceling the fixation of the welded aluminum-plastic pulley 6. At this time, the aluminum-plastic pulley 6 is supported by the vertical toothed rod 23. Then, the next reinforcing ring 14 is installed on the second fixing component. The connecting frame 13 is then moved to the left, allowing the rotating component to drive the vertical toothed rod 23 to move downwards, so that the welded aluminum-plastic pulley 6 can be placed on the roller conveyor 22 for transfer. When the welded aluminum-plastic pulley 6 moves downwards, the next aluminum-plastic pulley 6 is placed in and fixed by the fixed seat 5. When the connecting frame 13 is reset to the right, the vertical toothed rod 23 contacts the bottom of the next aluminum-plastic pulley 6, thus enabling the welded aluminum-plastic pulley 6 to be placed on the roller conveyor 22 for transfer in a cyclical manner, making it more efficient to use.
