[0005] To achieve the above object, the utility model provides the following technical scheme:

[0006] The utility model provides a steel band wave tube production is with steel band unwinding device, including the bottom plate, the upper end rear side of bottom plate is fixedly connected with the vertical board, the outer wall right side of vertical board is fixedly connected with first housing, be equipped with the mechanism of unwinding in first housing's inside, the left side of vertical board is fixedly connected with the cylinder, the rear end of cylinder is installed the cylinder cover, the inner wall of cylinder is fixedly connected with second housing, be equipped with fixed mechanism in second housing's inside, the lower end of cylinder is fixedly connected with bottom plate, the inner wall of first housing is slidable with two bending plate connections.

[0009] Preferably, the outer wall of the second motor is fixedly connected with the first housing, and the upper end of the threaded block is fixedly connected with a bending plate.

[0010] Preferably, the fixed mechanism comprises a third motor, the output shaft of the third motor is fixedly connected with a rotating disc, a plurality of sliding grooves are processed on the inner wall of the rotating disc, the inner wall of the sliding groove is slidably connected with a sliding block, the lower end of the sliding block is fixedly connected with two jacks, and the outer wall of the jack is slidably connected with a limiting block.

[0011] Preferably, the outer wall of the limiting block is fixedly connected with the second housing, and the outer wall of the third motor is fixedly connected with the cylinder.

[0012] The steel band wave tube production steel band unwinding device has the beneficial effects that: through the cooperation of the fixed mechanism and the cylinder, the output shaft of the third motor drives the rotating disc to rotate, the rotating disc drives a plurality of sliding grooves to rotate around the center of the rotating disc as the rotation center, the sliding groove movement drives the sliding block to move outward, the sliding block moves outward to drive the jack to move outward, the jack is limited to move linearly by the limiting block, and after the outer wall of the plurality of jacks abuts against the inner wall of the steel band, the third motor is stopped, so that the steel band is fixed, the steel band is fixed by the fixed mechanism, manual rotating handle fixing of the staff is not needed, the physical strength of the staff is saved, and manual labor is reduced.

[0013] Through the cooperation of the uncoiling mechanism and the circular rollers, the output shaft of the second motor rotates forward, driving the first gear to rotate, which in turn drives the two second gears to rotate synchronously. The synchronous rotation of the two second gears drives the threaded rods to rotate synchronously. Because the threads of the two threaded rods are in opposite directions, the synchronous rotation of the threaded rods drives the two threaded blocks to move towards each other. The threaded blocks are limited by the limiting rod to move linearly. The two threaded blocks move towards each other, driving the two bent plates to move towards each other, which in turn drives the two circular rollers and the first motor to move towards each other. When the two circular rollers press the steel strip together, the second motor stops. Because the threaded connection between the threaded blocks and the threaded rods has a self-locking function, it can ensure that the position of the circular rollers is fixed. Then the first motor is started. The output shaft of the first motor rotates, driving the lower circular roller to rotate. Because the two circular rollers are pressed together, they drive the steel strip to move to the right. Since the ends of the multiple push rods are equipped with balls, the steel strip can rotate, thus realizing the uncoiling of the steel strip. By cooperating with one motor and two circular rollers, a portion of the steel strip is moved, thereby achieving the purpose of uncoiling. Compared to driving the entire steel strip to rotate, the power of the motor required is lower. This saves energy during production and reduces the wear and tear on the motor caused by excessive power to a certain extent, extending the motor's life and thus reducing production costs.

The rotation of the output shaft of the third motor 801 drives the turntable 802 to rotate. The inner wall of the turntable 802 is machined with multiple sliding grooves 803. The rotation of the turntable 802 drives the sliding grooves 803 to rotate around the rotation center of the turntable 802.

The ends of each push rod 806 are machined with balls to facilitate the rolling of the steel belt.

[0029] Working principle:

[0030] The production of corrugated steel pipes uses a steel strip unwinding device to unwind the steel strip coils.

[0031] Work process:

[0032] The worker opens the tube cover 6, then aligns the center of the steel coil with the center of the second outer shell 7, and inserts the fixing mechanism into the hollow part in the middle of the steel coil (e.g., Figure 2 Then, push the steel coil until it is flush against the inner wall of the rear end of the cylinder 5, and then start the third motor 801 (e.g., Figure 4 The output shaft of the third motor 801 rotates forward, driving the turntable 802 to rotate. The rotation of the turntable 802 drives multiple sliding grooves 803 to rotate around the center of the turntable 802. Due to the restriction of the limit block 805, the movement of the sliding groove 803 drives the slider 804 to move outward. The outward movement of the slider 804 drives the push rod 806 to move outward. The push rod 806 is limited by the limit block to move linearly. After the outer wall of the multiple push rods 806 abuts against the inner wall of the steel strip, the third motor 801 (the third motor 801 is a servo motor with self-locking capability) stops, thereby fixing the steel coil. Then, one end of the steel coil extends out from the right opening of the cylinder 5, and then the cylinder cover 6 is closed.

[0033] The steel strip extending from the steel coil is placed onto the lower roller 11 (e.g., Figure 1 Then, the second motor 301 is started. The output shaft of the second motor 301 rotates forward, driving the first gear 302 to rotate, which in turn drives the two second gears 303 to rotate synchronously (e.g., Figure 5The two second gears 303 rotate synchronously, driving the threaded rods 304 to rotate synchronously. Because the threads of the two threaded rods 304 are opposite, the synchronous rotation of the threaded rods 304 drives the two threaded blocks 305 to move towards each other. The threaded blocks 305 are limited by the limiting rods 306 to move linearly. The movement of the two threaded blocks 305 drives the two bent plates 10 to move towards each other, thereby driving the two round rollers 11 and the first motor 9 to move towards each other. When the two round rollers 11 press the steel strip together, the second motor 301 stops. Because the threaded connection between the threaded blocks 305 and the threaded rods 304 has a self-locking function, it can ensure that the position of the round rollers 11 is fixed. Then the first motor 9 is started. The output shaft of the first motor 9 rotates, driving the lower round rollers 11 to rotate. Because the two round rollers 11 are pressed together, they drive the steel strip to move to the right. Because the ends of the multiple push rods 806 are equipped with balls, the steel strip can rotate, realizing the unwinding of the steel strip. After all is completed, all power is turned off, and the output shaft of the second motor 301 is reversed, causing the two round rollers 11 to move in the opposite direction. The reset working principle is the opposite of the above, which is beneficial for the next processing.
