[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] An embodiment of this double-head band saw is as follows:

[0030] Please see Figures 1-8 A double-head band saw includes a cutting table 1 and a sawing frame 3. There are two sets of sawing frames 3, and a sawing band 41 is installed in each set of sawing frames 3.

[0031] The sawing bands 41 in the two sets of sawing frames 3 travel in the same or opposite directions, and the two sets of sawing bands 41 are located on the same vertical plane. By using the two sets of sawing bands 41 in cooperation, the material to be cut can be sawn, which can improve the efficiency of material sawing.

[0032] It should be noted that the sawing frame 3 is equipped with multiple drive wheels 4 inside. One of the drive wheels 4 is driven to rotate by a motor installed inside the sawing frame 3. The sawing belt 41 is sleeved on the surface of the multiple drive wheels 4. The synchronous rotation of the multiple drive wheels 4 in the same direction drives the sawing belt 41 to run. The sawing belt 41 in the running state contacts the material to be cut in order to perform sawing processing on the material.

[0033] It should also be noted that the cutting frame 1 includes a front support 101 and a rear support 102; the sawing frame 3 is U-shaped and distributed laterally, which facilitates the installation of sliding structures on the front and rear sides of the bottom of the sawing frame 3 to improve the stability of the sawing frame 3's movement, and also facilitates the installation of the sawing strip 41. The bottom of the sawing frame 3 is provided with a front support 31 and a rear support 32, which serve as sliding structures for the sawing frame 3. The front support 31 and the rear support 32 are slidably disposed in the front support 101 and the rear support 102, respectively; the two sets of sawing frames 3 are driven by independent drive components, which drive and control the movement of the sawing frame 3, thereby driving the sawing strip 41 to move.

[0034] It should be noted that guide rails 5 are fixedly installed on the upper surfaces of the front support 101 and the rear support 102, and rollers 8 are rotatably installed inside the front support 31 and the rear support 32. The rollers 8 are adapted to the corresponding guide rails 5, and the rollers 8 and the guide rails 5 realize the movement support and guidance of the sawing frame 3.

[0035] The drive assembly includes a motor module 6, a first coupling 61, and a second coupling 62. The motor module 6 is equipped with dual output shafts. The first coupling 61 and the second coupling 62 are respectively connected to the two output shafts. The main shaft 63 is rotatably mounted in both the front support 31 and the rear support 32. The other ends of the first coupling 61 and the second coupling 62 are respectively connected to the corresponding main shaft 63. The main shaft 63 is connected to the corresponding roller 8 through a gear set 7. The gear set 7 has a large gear and a small gear. The small gear is fixedly mounted on the main shaft 63, the large gear is coaxially mounted with the roller 8, and the small gear is meshed with the large gear.

[0036] Specifically, when it is necessary to control the movement of the sawing belt 41, the motor module 6 is started. The motor module 6 drives the first coupling shaft 61 and the second coupling shaft 62 to rotate synchronously in the same direction. The first coupling shaft 61 and the second coupling shaft 62 respectively drive the corresponding main shaft 63 to rotate. The main shaft 63 drives the roller 8 to rotate through the gear set 7. The roller 8 cooperates with the guide rail 5 to drive the sawing frame 3 to move. The sawing frame 3 drives the sawing belt 41 to move.

[0037] Based on this, a material platform 2 is fixedly installed above the cutting frame 1, and a receiving box 9 is installed below the material platform 2. A fan is installed inside the receiving box 9, and the upper surface of the receiving box 9 is a receiving mesh plate 91. A discharge box 92 is installed on one side of the receiving box 9 extending from the discharge platform 2. When the fan runs, a negative pressure is generated below the receiving mesh plate 91, and the sawing debris is adsorbed and conveyed to the receiving box 9. A collection cart 10 is set below the discharge box 92, and the debris enters the collection cart 10 through the outlet on the lower surface of the discharge box 92.

[0038] It should be noted that the sawing section of the sawing belt 41 is installed vertically at the opening of the sawing frame 3, and the sawing section of the sawing belt 41 is located on the front side of the material table 2.

[0039] Based on this, a feeding platform 11 is provided on the front side of the material platform 2, and the material to be cut is conveyed to the material platform 2 by the feeding platform 11.

[0040] Working principle of a double-head band saw:

[0041] The material to be sawed is placed on the feeding platform 11, and the area to be sawed is positioned in the sawing direction of the sawing belt 41. The motor module 6 is started, and the motor module 6 simultaneously drives the first coupling shaft 61 and the second coupling shaft 62 to rotate in the same direction. The first coupling shaft 61 and the second coupling shaft 62 drive the rollers 8 to rotate through the corresponding main shaft 63 and gear set 7, respectively. The rollers 8 inside the front support 31 and the rear support 32 cooperate with the guide rail 5 to drive the sawing frame 3 to move. The sawing frame 3 drives the sawing belt 41 to move. The sawing belts 41 in both sets of sawing frames 3 move towards the area to be sawed in the material until they come into contact with the material, and then the material is sawed. After the two sets of sawing frames 3 complete the sawing, they are reset to the initial state.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention.
