[0006] Furthermore, the first drive assembly adopts a lead screw drive assembly.

[0007] Furthermore, the second drive assembly adopts a lead screw drive assembly.

[0008] Furthermore, the guide bar feeding and welding mechanism includes a feeding wheel, a welding gun, a third drive assembly, and a fourth drive assembly.

[0009] Furthermore, the third drive component adopts a lead screw drive component.

[0010] Furthermore, the fourth drive component adopts a lead screw drive component.

[0011] Furthermore, a limiting assembly is provided between the active drive roller and the driven drive roller. The limiting assembly includes a mounting plate, and two limiting plates are mounted opposite each other on the top of the mounting plate.

[0012] Furthermore, the limiting plate is fixedly mounted on the mounting plate by bolts, and the mounting plate is provided with a strip groove, which allows the bolts to slide inside.

[0013] The beneficial effects of this utility model include: This utility model provides a belt guide bar welding machine, wherein the first drive assembly is used to drive the heating wheel to move linearly towards or away from the central axis of the driven transmission roller, and the second drive assembly is used to drive the heating wheel to move linearly along the central axis of the driven transmission roller, so that the side wall of the heating wheel contacts the welding surface of the belt and preheats the welding surface of the belt to soften the welding surface of the belt, so that the welding and fixing between the guide bar and the belt is more firm.

Detailed Implementation

[0017] 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 the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0018] This utility model embodiment provides a belt guide bar welding machine, such as Figure 1-2As shown, the welding machine includes a driving roller 1 and a driven roller 2 arranged in parallel. A belt can be wound around the driving roller 1 and the driven roller 2. The welding machine also includes a guide bar feeding and welding mechanism 3, which is used to feed the guide bar onto the belt and weld the guide bar onto the belt at the same time. The welding machine also includes a preheating mechanism 4, which includes an electric heating wheel 41, a first drive assembly 42 and a second drive assembly 43. The first drive assembly 42 is used to drive the electric heating wheel 41 to move linearly towards or away from the central axis of the driven roller 2. The second drive assembly 43 is used to drive the electric heating wheel 41 to move linearly along the central axis of the driven roller 2 so that the side wall of the electric heating wheel 41 contacts the welding surface of the belt and preheats the welding surface of the belt to soften the welding surface of the belt, so that the welding and fixing between the guide bar and the belt is more secure.

[0019] In this embodiment, the first drive component 42 is a lead screw drive component.

[0020] For the first drive assembly 42, it only needs to be able to drive the heating wheel 41 to move linearly toward or away from the central axis of the driven transmission roller 2. Therefore, it is not limited to using a screw drive assembly. For example, in some other embodiments, the first drive assembly 42 adopts a belt drive mechanism or a gear and rack drive assembly.

[0021] In this embodiment, the second drive component 43 is a lead screw drive component.

[0022] For the second drive assembly 43, it only needs to be able to drive the heating wheel 41 to move along the central axis of the driven transmission roller 2. Therefore, it is not limited to the form of a screw drive assembly. For example, in some other embodiments, the second drive assembly 43 adopts one of a belt drive mechanism or a gear and rack drive assembly.

[0023] In this embodiment, the guide bar feeding and welding mechanism 3 includes a feeding wheel 31, a welding gun 32, a third drive assembly 33, and a fourth drive assembly 34. The third drive assembly 33 is used to drive the feeding wheel 31 and the welding gun 32 to move linearly towards or away from the central axis of the drive roller 1. The fourth drive assembly 34 is used to drive the feeding wheel 31 and the welding gun 32 to move linearly along the central axis of the drive roller 1 to move the feeding wheel 31 and the welding gun to the welding position of the guide bar and the belt. When the feeding wheel 31 and the welding gun 32 move to the corresponding position, the guide bar can be conveyed to the belt through the feeding wheel 31, and at the same time, the guide bar can be welded to the belt through the welding gun 32.

[0024] In this embodiment, the third drive component 33 is a lead screw drive component.

[0025] For the third drive assembly 33, it only needs to be able to drive the feed wheel 31 and the welding gun 32 to move linearly toward or away from the central axis of the drive roller 1. Therefore, it is not limited to the form of a screw drive assembly. For example, in some other embodiments, the third drive assembly 33 adopts one of a belt drive mechanism or a gear and rack drive assembly.

[0026] In this embodiment, the fourth drive component 34 is a lead screw drive component.

[0027] For the fourth drive assembly 34, it only needs to be able to drive the feed wheel 31 and the welding gun 32 to move linearly along the central axis of the drive roller 1. Therefore, it is not limited to the form of a screw drive assembly. For example, in some other embodiments, the fourth drive assembly 34 adopts a belt drive mechanism or a gear and rack drive assembly.

[0028] In this embodiment, a limiting component 5 is provided between the driving roller 1 and the driven roller 2. The limiting component 5 includes a mounting plate 51, and two limiting plates 52 are mounted opposite each other on the top of the mounting plate 51. The position of the belt can be limited by the two limiting plates 52 to prevent the belt from deviating during movement, so that the guide bar can be accurately welded to the welding position of the belt. At the same time, the limiting plates 52 are fixedly mounted on the mounting plate 51 by bolts 53. The mounting plate 51 is provided with a strip groove 511. The longitudinal section of the strip groove 511 is T-shaped. The bolts 53 can slide inside the strip groove 511, so that the installation position of the limiting plates can be adjusted, thereby adjusting the distance between the two limiting plates 52 to limit the position of belts of different widths. At the same time, the longitudinal section of the limiting plate 52 is L-shaped, which can prevent the belt from tilting upward.

[0029] In principle, before the guide bar is welded to the belt, the first drive assembly 42 drives the heating wheel 41 to move linearly towards the central axis of the driven transmission roller 2, and the second drive assembly 43 drives the heating wheel 41 to move linearly along the central axis of the driven transmission roller 2, so that the side wall of the heating wheel 41 contacts the welding surface of the belt. During the belt movement, the heating wheel 41 preheats the welding surface of the belt to soften it. When the guide bar is welded to the belt, the heating wheel 41 is separated from the belt. Simultaneously, the third drive assembly 33 drives the feeding wheel 31 and the welding gun 32 to move linearly towards or away from the central axis of the drive roller 1, and the fourth drive assembly 34 drives the feeding wheel 31 and the welding gun 32 to move linearly along the central axis of the drive roller 1, so as to move the feeding wheel 31 and the welding gun 32 to the welding position of the guide bar and the belt. When the feeding wheel 31 and the welding gun 32 move to the corresponding position, the guide bar can be conveyed to the belt through the feeding wheel 31, and the guide bar can be welded to the belt through the welding gun 32.
