Referring to fig. 1 to 5, a surfboard welding machine according to some embodiments of the present invention includes a frame 100 having a substantially elongated shape, it should be noted that the shape of the frame 100 may also be circular, square or other irregular shapes, and is not limited to the elongated shape, and specifically, according to actual needs, the frame 100 is provided with a worktable 110 for carrying a workpiece; one end of the rack 100 is provided with two sets of welding mechanisms 200, the two sets of welding mechanisms 200 can perform ultrasonic welding on a workpiece, and the number of the welding mechanisms 200 can be set as one set, three sets, four sets or multiple sets, which can be determined according to actual needs.

The frame 100 is provided with a conveying mechanism for conveying a workpiece, the conveying mechanism can drive the workpiece to move towards the welding mechanism 200 along the workbench 110, the conveying mechanism comprises an upper pressing roller 310 and a lower pressing roller 320 which are rotatably installed on the frame 100, and a gap between the upper pressing roller 310 and the lower pressing roller 320 is adjustable, as shown in fig. 2, the frame 100 is provided with a mounting seat 101 which can move up and down, the upper pressing roller 310 is rotatably installed on the mounting seat 101, the mounting seat 101 is connected with a first air cylinder 102 for driving the mounting seat 101 to move up and down, and the first air cylinder 102 is fixedly installed on the frame 100. When a workpiece is conveyed, the first air cylinder 102 drives the mounting seat 101 to drive the upper compression roller 310 to move downwards, and the upper compression roller 310 and the lower compression roller 320 move relatively close to each other, so that the gap is reduced; when the workpiece is removed, the first air cylinder 102 drives the mounting seat 101 to drive the upper pressing roller 310 to move upwards and lift, and the upper pressing roller 310 and the lower pressing roller 320 move away relatively, so that the gap is increased.

In some embodiments of the present invention, the rack 100 is provided with a mounting seat 101 capable of moving up and down, the upper pressing roller 310 is rotatably mounted on the mounting seat 101, and the mounting seat 101 is connected with an electric push rod for driving the lifting of the mounting seat 101, and the electric push rod is fixedly mounted on the rack 100. When a workpiece is conveyed, the electric push rod drives the mounting seat 101 to drive the upper compression roller 310 to move downwards, and the upper compression roller 310 and the lower compression roller 320 move relatively close to each other, so that the gap is reduced; when the workpiece is removed, the electric push rod drives the mounting seat 101 to drive the upper pressing roller 310 to move upwards and rise, and the upper pressing roller 310 and the lower pressing roller 320 move away relatively, so that the gap is increased. Since the gap between the upper pressure roller 310 and the lower pressure roller 320 is adjustable in the prior art, it is not described in detail herein.

The upper pressing roller 310 is connected with a first rotation driving mechanism 311 in a transmission manner, the lower pressing roller 320 is connected with a second rotation driving mechanism 321 in a transmission manner, the first rotation driving mechanism 311 and the second rotation driving mechanism 321 are arranged on the rack 100, wherein the speed of the upper pressing roller 310 driving the workpiece to move along the workbench 110 is greater than the speed of the lower pressing roller 320 driving the workpiece to move along the workbench 110.

In order to make the structure of the conveying mechanism more compact, in some embodiments of the present invention, the first rotation driving mechanism 311 and the second rotation driving mechanism 321 are both motors. By adopting two motors to correspondingly drive the upper pressing roller 310 and the lower pressing roller 320 to rotate, the rotation of the upper pressing roller 310 and the lower pressing roller 320 can be smoother, and the structure of the conveying mechanism can be simplified.

It is understood that the first rotation driving mechanism 311 and the second rotation driving mechanism 321 may also adopt other structures, for example, both the first rotation driving mechanism 311 and the second rotation driving mechanism 321 are rotary cylinders (not shown), and the structure is also possible and may be determined according to the specific requirement.

The speed of the workpiece driven by the upper pressing roll 310 to move along the workbench 110 is set to be higher than the speed of the workpiece driven by the lower pressing roll 320 to move along the workbench 110, so that when the upper pressing roll 310 and the lower pressing roll 320 are matched to clamp and convey the workpiece, the upper material which is in contact with the upper pressing roll 310 and is longer in length can be uniformly paved on the surface of the lower material which is in contact with the lower pressing roll 320 by the upper pressing roll 310, the welding mechanism 200 can conveniently weld and compound the upper material and the lower material, and the technical problem that the upper material protrudes out of the lower material or folds occur when the traditional surfboard welding machine welds the composite material is solved.

In order to allow the production of the conveying mechanism, in some embodiments of the present invention, the outer diameter of the upper pressure roller 310 is the same as the outer diameter of the lower pressure roller 320, and the rotation speed of the upper pressure roller 310 is greater than that of the lower pressure roller 320. That is, the upper roller 310 and the lower roller 320 have the same size, which is convenient for production and manufacture, the first rotation driving mechanism 311 for driving the upper roller 310 to rotate can be a motor with a relatively high rotation speed, and the second rotation driving mechanism 321 for driving the lower roller 320 to rotate can be a motor with a relatively low rotation speed, by adopting the above structure, the speed at which the upper roller 310 drives the upper material to move along the workbench 110 to be close to the welding mechanism 200 can be greater than the speed at which the lower roller 320 drives the lower material to move along the workbench 110 to be close to the welding mechanism 200. Therefore, the upper material which is located on the upper layer and has a longer length can be uniformly laid on the surface of the lower material which is in contact with the lower pressing roller 320 in the moving process, so that the welding mechanism 200 can weld and compound the upper material and the lower material conveniently.

Specifically, the first rotary driving mechanism 311 for driving the upper pressure roller 310 to rotate and the second rotary driving mechanism 321 for driving the lower pressure roller 320 to rotate both use motors with the same rotation speed. Because the two motors respectively drive the upper pressing roller 310 and the lower pressing roller 320 to rotate at the same speed, and the outer diameter of the upper pressing roller 310 is greater than that of the lower pressing roller 320, the speed at which the upper pressing roller 310 drives the upper material to move along the workbench 110 close to the welding mechanism 200 is greater than the speed at which the lower pressing roller 320 drives the lower material to move along the workbench 110 close to the welding mechanism 200.
