And simultaneously, the utility model discloses straining device 2 and two installation guiding mechanism 3 of embodiment all have the driving piece, and this driving piece accessible numerical control system controls for band saw adjustment easy operation is swift.
In the band saw mounting structure, the saw band power wheel 1 is positioned at the rear lower part of the mounting and adjusting mechanism 3, the power of the saw band power wheel 1 is better output to a band saw blade, and the operation of the band saw is more stable.
In order to improve the structural stability and facilitate adjustment, the two mounting adjustment mechanisms 3 are divided into a first mounting adjustment mechanism 31 and a second mounting adjustment mechanism 32, and the first mounting adjustment mechanism 31 and the second mounting adjustment mechanism 32 are arranged side by side; the tensioning mechanism 2 is located behind the first mounting and adjusting mechanism 31, and the saw belt wheels 15 of the tensioning mechanism and the saw belt wheels are arranged oppositely. The working section of the saw belt is formed between the two installation adjusting mechanisms which are arranged side by side, and the tensioning mechanism 2 is located behind the working section, so that the tensioning mechanism and the saw belt of the working section are not interfered with each other, the installation stability of the saw belt is improved, and the adjustment and tensioning operation of the saw belt is more convenient.
Specifically, the saw band between the tensioning mechanism 2 and the saw band power wheel 1 is perpendicular to the saw band between the tensioning mechanism 1 and the first mounting adjustment mechanism 31. Thus, the stability of the structure can be further improved.
In order to improve the stability of the adjusting action and the reliability of the structure, the tensioning mechanism 2 and the two mounting adjusting mechanisms respectively comprise a mounting plate 11, a linkage piece 13 and a guide mechanism 14, and the driving piece 12 and the guide mechanism 14 are respectively mounted on the same side surface of the mounting plate 11; one end of the linkage piece 13 is connected with the driving piece 12, the other end of the linkage piece is connected with the saw belt wheel 15, and the driving piece 12 drives the saw belt wheel 15 to move horizontally through the linkage piece 13; a saw wheel 15 is movably mounted to the mounting plate 11 by a guide mechanism 14. The tensioning mechanism 2 and the two installation adjusting mechanisms are composed of an installation plate 11, a driving piece 12, a linkage piece 13, a guide mechanism 14 and a saw belt wheel 15, the driving piece 12 drives the saw belt wheel 15 to move along the guide mechanism 14 through the linkage piece 13, and the structure is simple and reliable.

The connecting plate 143 is installed through the two groups of guide mechanisms, so that the installation structure of the connecting plate 143 is more stable and can bear larger acting force, and the saw belt wheel 15 is more stably installed; and the translational movement of the connecting plate 143 is more stable.
Specifically, the saw pulley 15 includes a wheel 151 and a main shaft 152, the wheel 151 is rotatably mounted on the main shaft 152 through a bearing, and an end of the main shaft 152 is fixed to the connecting plate 143; the wheel 151 comprises an outer rim 1511 and an inner rim 1512, the outer rim 1511 and the inner rim 1512 are connected by a ring plate 1513, the inner rim 1511 is rotatably connected to the spindle 152, and the width of the outer rim 1511 matches the width of the saw band.

While the saw belt applies a certain pressure to the saw pulley 15 during the operation process, at this time, if the contact area between the inner ring 1512 and the spindle 152 is small, the saw pulley 15 may be skewed. Therefore, the inner ring 1512 with a larger width is designed, and the contact area between the inner ring 1512 and the spindle 152 is increased, so that the saw belt wheel 15 can be more stably mounted, can bear larger pressure from the saw belt, and improves the operation stability of the saw belt.
In order to further improve the adjustment precision of the saw belt wheel 15, the driving part 12 is a servo motor, and the linkage part 13 is a ball screw; one end of the ball screw is in transmission connection with the servo motor, and the other end of the ball screw is rotatably arranged on the mounting plate 11; the bottom of the connecting plate 143 is provided with a threaded sleeve, and the threaded sleeve is in threaded connection with the ball screw. The servo motor is used as a driving piece and the ball screw is used as a linkage piece, so that the micro distance adjustment can be realized, the adjustment precision is improved, the numerical control adjustment can be realized, and the automation degree of the cutting equipment is improved.
Specifically, the servo motor and the ball screw are in transmission connection through the speed reducer 16, so that the adjusting process is more stable and the micro adjustment is favorably realized. Specifically, the mounting plate 11, the connecting plate 143, and the ball screw are parallel to each other.
