Description

Technical Field

[0001] The utility model relates to the technical field of feeding adjustment mechanisms, in particular to a feeding adjustment mechanism for a shearing machine. Background Art

[0002] The shearing machine is mainly suitable for metallurgy, construction, metal processing and other industries. By replacing the blade, it can be used to cut flat steel, round steel, square steel, angle steel and other metal plates of various specifications to meet the needs of all parties.

[0003] The bars to be transported are generally long, so the feeding rack is generally also long. In the prior art, when feeding, a motor is usually required to drive a transmission pulley to rotate the transmission pulley, so as to push the bars through the inner wall of the transmission pulley for transportation. Generally, the transmission pulley is of fixed size. In order to adapt to the transmission of bars of more sizes, the size of the transmission pulley cannot be designed too small. However, when feeding bars with smaller diameters, the surface of the bars is not easy to contact the inner wall of the transmission pulley, so that the friction between the feeding mechanism and the bars is weakened, and good transmission cannot be performed. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a feeding adjustment mechanism for a shearing machine, which solves the problems mentioned in the above background.

[0005] The utility model provides the following technical solutions:

[0006] The utility model discloses a feeding adjustment mechanism for a shearing machine, comprising two groups of support plates and a plurality of support feet welded at the bottom of the support plates.

[0007] A transmission pulley is installed between two sets of support plates;

[0008] Fixing rod 1, fix between supporting legs;

[0009] A movable rod, movably connected to the fixed rod via a collar fixed at one end;

[0010] The transmission roller is sleeved on the outer ring of the movable rod and is located on one side of the transmission pulley;

[0011] A fixed block is fixed to the end of the movable rod away from the collar, and a mounting hole is provided on the side thereof;

[0012] The connecting rod is installed in the installation hole provided in the fixing block;

[0013] The cylinder, the telescopic section and the connecting rod are movably connected.

[0014] Furthermore, a sizing device is installed on the surface of one group of support plates.

[0015] Furthermore, the outer ring of the rotating shaft of one set of transmission pulleys is connected to a transmission chain, one end of the transmission chain is connected to a motor, and the motor is installed on the side of one of the supporting legs.

[0016] Furthermore, a protective shell is installed on a side of the support plate close to the motor.

[0017] Furthermore, a gasket is fixed to the outer wall of the movable rod, and the gasket is located at an end of the transmission roller away from the fixed block.

[0018] Furthermore, a second fixing rod is sleeved on the bottom of the cylinder, and two ends of the second fixing rod are fixed to the side walls of the supporting foot.

[0019] Compared with the prior art, the utility model has the following beneficial effects:

[0020] The utility model arranges a transmission roller on the side of a transmission pulley, connects each group of transmission rollers through a connecting rod, pushes the connecting rod to move through a cylinder, and drives the transmission roller to change its inclination angle, so that the included angle between the transmission roller and the transmission pulley is reduced. The reduced included angle can lift a rod with a smaller diameter, so that the surface of the rod contacts the inner wall of the transmission pulley, thereby increasing friction and improving the transmission efficiency of the rod. The rod is driven to be transmitted through the rotation of the transmission pulley. When the rod is transported, the transmission roller rotates with the movement of the rod, thereby reducing the resistance to the transmission of the rod. BRIEF DESCRIPTION OF THE DRAWINGS

The bottom of the transmission roller 10 is limited by the gasket 11 to prevent the transmission roller 10 from falling to the bottom of the movable rod 9, thereby preventing the transmission roller 10 from touching the support plate 1, and the connecting rod 13 is installed in the mounting hole opened in the fixed block 12; the cylinder 14, the telescopic section is movably connected with the connecting rod 13, and the connecting rod 13 can be pushed to move by the cylinder 14, thereby driving the change of the inclination angle of the transmission roller 10, so that the angle between the transmission roller 10 and the transmission pulley 3 is reduced, and the reduced angle can support rods with smaller diameters, so that the surface of the rod contacts the inner wall of the transmission pulley 3, and the rod is driven to be transmitted by the rotation of the transmission pulley 3. When the rod is conveyed, the transmission roller 10 rotates with the movement of the rod, reducing the resistance of the rod transmission. A second fixing rod 15 is sleeved on the bottom of the cylinder 14 , and both ends of the second fixing rod 15 are fixed to the side walls of the supporting foot 2 , so that the bottom of the cylinder 14 is limited by the second fixing rod 15 .

[0029] A sizing device 4 is installed on the surface of one group of support plates 1, and the sizing device 4 is located near the transmission pulley 3. The sizing roller of the sizing device 4 is located on the top of one group of transmission pulleys 3. The distance that the transmission pulley 3 transports the rod can be measured by the sizing device 4, so as to calculate the remaining material of the rod.

[0030] The outer ring of the rotating shaft of one group of transmission pulleys 3 is connected to the transmission chain 5, one end of the transmission chain 5 is connected to the motor 6, and the motor 6 is installed on the side of one of the supporting legs 2.

[0031] Working principle: transport the rod to between two groups of support plates 1, make the rod fall from the top to the inside of the support foot 2, start the motor 6, drive the transmission chain 5 through the motor 6, the transmission chain 5 drives the rotating shaft of the transmission pulley 3 to rotate, so that each group of transmission pulleys 3 rotates through the connected conveyor belt, when the rod falls into the transmission pulley 3, the surface will contact the two sides of the inner wall of the transmission pulley 3, and the rotation of the transmission pulley 3 can drive the rod to move toward the shearing machine. When moving rods with smaller diameters, in order to prevent the surface of the rod from failing to touch the two sides of the inner wall of the transmission pulley 3, thereby affecting the transportation of the rod, the cylinder 14 can be used to push The connecting rod 13 is moved, so that the connecting rod 13 drives one end of the movable rod 9 to lift upward through the fixed block 12, so that the transmission roller 10 on the outer ring of the movable rod 9 forms a smaller angle with the inner wall of one side of the transmission pulley 3. After the bar falls, the surface of the bar contacts the inner wall of one side of the transmission pulley 3 and the surface of the transmission roller 10 at the same time, and the bar is driven to move by the rotation of the transmission pulley 3. When the bar moves with the rotation of the transmission pulley 3, the transmission roller 10 rotates around the movable rod 9 with the movement of the bar, thereby reducing the resistance when the bar moves. By changing the angle of the transmission roller 10, the feeding mechanism can adapt to the movement of bars of more sizes.
