Description

Technical Field

[0001] The invention relates to the technical field of metal cutting, and in particular to automatic cutting equipment for producing metal packaging barrels. Background Art

[0002] Metal packaging barrels are thin-walled containers made of metal sheets and are widely used in packaging in a variety of industries, such as food, medicine, daily necessities, instruments, industrial products and even munitions. These containers are not limited to storing liquids, but can also be used to package solid items.

[0003] When processing metal packaging barrels, first unfold the wide steel coil, then cut it longitudinally by a set of blades to obtain a sheet of the required width; then the sheet is cut into strips of fixed length by a transverse shearing unit; then the strip material is rolled into the required cylindrical shape by a winding machine, and after a series of subsequent beautification processes, a metal packaging barrel is obtained; in the above processing steps, the shearing step of cutting the sheet into a plurality of evenly divided strips is a relatively important step.

[0004] Existing metal cutting machines for cutting sheet materials into strips generally only have a single cutting tool. A sheet material needs to be cut multiple times to completely cut out multiple strips of the same specification.

At the same time, after the material is cut, manual assistance is required for unloading, and the material is generally thin, which may cause bumps during the movement process and easily injure workers. Overall, it will further affect work efficiency and work safety. Summary of the invention

[0057] During specific operation, the electric push rod 451 controls the pressure strip 452 to press the edge of the plate to prevent the rebound deformation of the plate from affecting subsequent cutting.

[0058] During use: S1: The conveyor 22 is controlled by motor 1 221 to transport the plate to the support 23. Since the conveyor 22 cannot transport the plate completely to the support 23, the mounting frame 1 244 is controlled to move upward as a whole by the electric push rod 243, and the mounting frame 1 244 drives the conveyor belt 241 to move upward, and then the first bevel gear 248 is controlled to rotate by motor 245, and the first bevel gear 248 drives the rear coupling 247 to rotate through the second bevel gear 249, and the conveyor belt 241 is driven by the belt roller 246 on the rear coupling 247 to perform a transmission movement. After the plate contacts the conveyor belt 241, it will continue to move forward.

[0059] S2: After moving to the cutting position, the conveyor belt 241 is lowered into the inside of the bracket 23, and then the motor five 413 is used to control the rotation of the bidirectional screw rod 411, and the two mounting plates 414 are controlled to move toward each other along the guide rod two 412, and the two mounting plates 414 drive the abutment plate 42 to press the left and right sides of the plate, so that the plate can be positioned in the middle of the bracket 23, and the abutment plate 42 is pressed by the spring 44, so that the abutment plate 42 has resilience, and the edge of the plate is elastically pressed, and then the electric push rod four 451 is used to control the pressure strip 452 to press the edge of the plate.

[0060] S3: The motor four 341 is used to control the rotation of any limit rotating shaft 37, and the connecting gear 343 drives the synchronous rotating shafts of each driving gear 342. The connecting gear 343 can make each driving gear 342 keep the same direction, and each limit rotating shaft 37 is controlled by each driving gear 342 to rotate synchronously and in the same direction to drive each cutting wheel 38 to rotate synchronously and in the same direction, and then the electric push rod three 32 controls the mounting frame two 33 to drive the cutting wheel 38 to move downward, so that the cutting wheel 38 is close to the plate, and at the same time, the motor three 314 is used to control the rotation of the translation screw 311, and the translation screw 311 controls the moving seat 315 to move forward and backward along the guide rod one 313, and the moving seat 315 drives the cutting wheel 38 to move forward and backward for cutting.

[0061] S4: When the cutting width of the strip needs to be changed, the front and rear movable blocks 393 are controlled by the dual-axis electric push rod 392 to move in opposite directions along the movable groove 3911, so as to change the spacing between the two hinge pins at the connecting position of the two X-shaped hinges at the center position, so that the X-shaped hinge changes the hinge angle, thereby changing the overall width of the X-shaped hinge arm group 394, so that the individual width of each X-shaped hinge is also changed and the width of each X-shaped hinge is kept consistent, thereby driving the connected movable arch seat 35 to change position and change synchronously and equidistantly, and the movable arch seat 35 drives the cutting wheel 38 to change the spacing, and the distance between the two movable arch seats 35, that is, the left and right spacing of the cutting wheel 38, can be intuitively read through the ruler 3951, representing the cutting width of the strip.

[0062] S5: After the cutting is completed, the positioning mechanism 4 is made to relax the entire plate, and then the conveyor belt 241 is moved upward as a whole to lift the strip, and then the strip is run to make it continue to move forward. At the same time, the hydraulic cylinder 26 is cooperated to control the support seat 23 to tilt toward the lower front side. Under the action of gravity, the cut strips will slide down more quickly, and the sliding strips are collected at the front of the frame 1.

For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
