Description

Technical Field

[0001] This utility model relates to the field of aluminum plate production technology, specifically to an aluminum plate strip foil straightening roller group. Background Technology

[0002] Aluminum plates are rectangular plates made by rolling aluminum ingots. They are widely used in many fields. During the rolling and processing, aluminum plates may deform and warp. In order to ensure the flatness of aluminum plates, aluminum plate foil straightening roller groups are needed to straighten the aluminum plates.

[0003] When using existing aluminum sheet and foil straightening roller sets, the aluminum sheet is usually passed between the straightening roller and the pressure roller. The straightening roller and the pressure roller contact the surface of the aluminum sheet and foil and generate pressure. Under continuous pressure, the bent part of the aluminum sheet is gradually straightened.

[0004] The existing aluminum sheet and foil straightening roller group has the following problems: when the aluminum sheet size is small, the aluminum sheet may deviate during feeding or straightening, which will affect the straightening work. To address this, we propose an aluminum sheet and foil straightening roller group. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide an aluminum plate foil straightening roller group. During the feeding or straightening process of the aluminum plate, the guide mechanism guides and prevents the aluminum plate from deviating, thus avoiding the situation where the straightening work of the aluminum plate is affected by the deviation of the aluminum plate. This can effectively solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an aluminum sheet and foil straightening roller group, including a straightening box, in which straightening rollers and adjustable pressure rollers are rotatably connected, and a guiding mechanism is also included;

[0007] The straightening mechanism includes a U-shaped seat 1, a limiting protrusion, a limiting groove, a connecting plate, a guide plate, a U-shaped seat 2, and a drive assembly. Limiting grooves are provided on both the front and rear side walls of the straightening box. The U-shaped seat 1 is slidably connected to the inside of each limiting groove via a limiting protrusion. A connecting plate is rotatably connected to the inside of each U-shaped seat 1. Adjustable guide plates are provided on both the front and rear side walls of the straightening box via the drive assembly. A U-shaped seat 2 is located at the right end of each guide plate. The end of the connecting plate furthest from the U-shaped seat 1 is rotatably connected to the inside of the U-shaped seat 2 on the same side. During the feeding or straightening process of the aluminum plate, the straightening mechanism guides and prevents deviation of the aluminum plate, avoiding any impact on the straightening process due to plate misalignment.

[0008] Furthermore, it also includes a microcontroller, which is fixedly connected to the front side of the straightening box. The input terminal of the microcontroller is electrically connected to an external power supply to facilitate the normal operation of the equipment.

[0009] Furthermore, the drive assembly includes a bidirectional lead screw and a sliding seat. The bidirectional lead screw is rotatably connected to the inside right side of the straightening box. The sliding seats are threadedly connected to both the front and rear sides of the outer surface of the bidirectional lead screw. The lower surface of the sliding seats is fixedly connected to the upper surface of the guide plate on the same side, which facilitates the normal operation of the drive and guide mechanism.

[0010] Furthermore, the front side of the straightening box is equipped with a motor, the rear end of the output shaft of the motor is fixedly connected to the front end of the bidirectional lead screw, and the input end of the motor is electrically connected to the output end of the microcontroller to provide driving force.

[0011] Furthermore, slots are provided on both the front and rear side walls of the straightening box, and a support frame is slidably connected between the two slots. The support frame is rotatably connected to evenly distributed pressure rollers. An electric push rod is provided in the mounting hole on the upper surface of the straightening box. The lower end of the telescopic shaft of the electric push rod is fixedly connected to the upper surface of the support frame. The input end of the electric push rod is electrically connected to the output end of the microcontroller, which facilitates the adjustment of the height of the pressure rollers.

[0012] Furthermore, a support roller is rotatably connected to the right side of the straightening box via a rotating shaft, and a second motor is provided on the front side of the straightening box. The rear end of the output shaft of the second motor is fixedly connected to the front end of the rotating shaft, and the input end of the second motor is electrically connected to the output end of the microcontroller, which facilitates the support and transportation of the aluminum plate.

[0013] Furthermore, a laser rangefinder is mounted on the front side of the straightening box via a fixed bracket. The laser rangefinder is bidirectionally electrically connected to the microcontroller, which facilitates distance measurement and ensures the normal operation of the straightening mechanism.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This aluminum sheet and foil straightening roller group has the following advantages:

[0015] The rotation of the bidirectional lead screw drives the guide plates to move towards each other through the sliding seat. Under the restriction of the limiting protrusion and the limiting groove, the guide plate drives the U-shaped seat one to slide through the U-shaped seat two and the connecting plate. At this time, the connecting plate deflects. The distance between the two guide plates is measured by the laser rangefinder until the distance between the two guide plates is slightly greater than the width of the aluminum plate. At this time, the aluminum plate will not be offset under the combined action of the connecting plate and the guide plate, thus avoiding the situation where the straightening work of the aluminum plate is affected by the offset of the aluminum plate.

[0022] Please see Figure 1-4This embodiment provides a technical solution: an aluminum sheet / strip foil straightening roller assembly, including a straightening box 1, with uniformly distributed straightening rollers 5 and adjustable pressure rollers 8 rotatably connected inside the straightening box 1, a guiding mechanism 3, and a microcontroller 2.

Uniformly distributed pressure rollers 8 are rotatably connected inside the support frame 7. An electric push rod 9 is provided in the mounting hole on the upper surface of the straightening box 1. The lower end of the telescopic shaft of the electric push rod 9 is fixedly connected to the upper surface of the support frame 7, and its input end is electrically connected to the output end of the microcontroller 2. A rotating shaft rotatably connects to the right side of the straightening box 1. The support roller 10 and the front side of the straightening box 1 are equipped with a motor 2 11. The rear end of the output shaft of the motor 2 11 is fixedly connected to the front end of the rotating shaft. The input end of the motor 2 11 is electrically connected to the output end of the microcontroller 2. The front side of the straightening box 1 is equipped with a laser rangefinder 12 through a fixed frame. The laser rangefinder 12 is bidirectionally electrically connected to the microcontroller 2. The operator operates the microcontroller 2 to turn on the motor 2 11. The motor 2 11 drives the support roller 10 to rotate and transport the aluminum plate between the straightening roller 5 and the pressure roller 8. Then, the electric push rod 9 is opened. The telescopic shaft of the electric push rod 9 drives the support frame 7 to move downward along the groove 6 until the outer surface of the pressure roller 8 contacts the upper surface of the aluminum plate. The straightening roller 5 and the pressure roller 8 contact the aluminum plate foil surface and generate pressure. Under continuous pressure, the bent part of the aluminum plate is gradually straightened.

[0023] The guiding mechanism 3 includes a U-shaped seat 31, a limiting protrusion 32, a limiting groove 33, a connecting plate 34, a guiding plate 35, a second U-shaped seat 36, and a driving assembly 37. Limiting grooves 33 are provided on both the front and rear side walls of the straightening box 1. The first U-shaped seat 31 is slidably connected to the inside of each limiting groove 33 via the limiting protrusion 32. The connecting plate 34 is rotatably connected to the inside of each U-shaped seat 31. Adjustable guiding plates 35 are provided on both the front and rear side walls of the straightening box 1 via the driving assembly 37. A second U-shaped seat 36 is provided on the right end of each guiding plate 35. The end of the connecting plate 34 away from the first U-shaped seat 31 is rotatably connected to the inside of the second U-shaped seat 36 on the same side. The driving assembly 37 includes a bidirectional lead screw 37. 1 and sliding seat 372 (the exposed part of the outer surface of the double-acting screw 371 is fitted with a bellows, the ends of which are fixedly connected to the side of the sliding seat 372 and the inner wall of the straightening box 1 respectively. The bellows are reserved with sufficient length so that when the sliding seats 372 move towards each other, the bellows at both ends in the middle contract and the bellows at both ends on both sides extend, so that when the guiding mechanism is working, the bellows always wrap and shield the double-acting screw 371 to prevent dust from affecting the threaded transmission of the double-acting screw 371 and the sliding seat 372). The double-acting screw 371 is rotatably connected to the right side inside the straightening box 1. The sliding seats 372 are threadedly connected to both the front and rear sides of the outer surface of the double-acting screw 371. The lower surface of the sliding seat 372 is also threaded. The upper surface of the guide plate 35 on the same side is fixedly connected. The front side of the straightening box 1 is equipped with a motor 4. The rear end of the output shaft of the motor 4 is fixedly connected to the front end of the bidirectional lead screw 371. The input end of the motor 4 is electrically connected to the output end of the microcontroller 2. Then, the motor 4 is turned on, and the output shaft of the motor 4 drives the bidirectional lead screw 371 to rotate. The rotation of the bidirectional lead screw 371 drives the threaded sliding seat 372 to move towards each other. The movement of the sliding seat 372 drives the U-shaped seat 36 to move through the guide plate 35, causing the connecting plate 34 to rotate. Since the length of the connecting plate 34 is fixed, the rotation of the connecting plate 34 drives the limiting protrusion 32 to slide in the limiting groove 33 through the U-shaped seat 31. At the same time, the... The distance between the two guide plates 35 is measured by the laser rangefinder 12. The laser rangefinder 12 emits a short laser pulse to the front side of the guide plate 35, and then measures the time it takes for the laser pulse to be reflected back by the guide plate 35 and received by the laser rangefinder 12. Combined with the speed of laser propagation in air, the distance between the laser rangefinder 12 and the guide plate 35 is calculated, and the distance between the two guide plates 35 is obtained. The distance between the two guide plates 35 is continued until it is slightly greater than the width of the aluminum plate. Then the motor 4 is turned off. At this time, under the combined action of the connecting plate 34 and the guide plate 35, the aluminum plate is prevented from shifting during feeding or straightening.

[0024] The working principle of the aluminum sheet and foil straightening roller assembly provided by this utility model is as follows: The operator operates the microcontroller 2 to turn on motor 11. Motor 11 drives the support roller 10 to rotate, transporting the aluminum sheet between the straightening roller 5 and the pressure roller 8. Then, motor 4 is turned on. The output shaft of motor 4 drives the bidirectional lead screw 371 to rotate. The rotation of the bidirectional lead screw 371 causes the threaded sliding seat 372 to move towards each other. The movement of the sliding seat 372 drives the U-shaped seat 36 to move via the guide plate 35, causing the connecting plate 34 to rotate. Since the length of the connecting plate 34 is fixed, the rotation of the connecting plate 34 drives the limiting protrusion 32 to slide within the limiting groove 33 via the U-shaped seat 31. Simultaneously, the distance between the two guide plates 35 is measured by the laser rangefinder 12. The laser rangefinder 12 emits a short laser beam from the front side of the front guide plate 35. The laser pulse is pulsed, and the time taken from emission to reflection by the front guide plate 35 and reception by the laser rangefinder 12 is measured. Combined with the propagation speed of the laser in the air, the distance between the laser rangefinder 12 and the front guide plate 35 is calculated, and the distance between the two guide plates 35 is obtained until the distance between the two guide plates 35 is slightly greater than the width of the aluminum plate. Then the motor 4 is turned off. At this time, under the combined action of the connecting plate 34 and the guide plate 35, the aluminum plate is prevented from shifting during feeding or straightening. Then the electric push rod 9 is turned on. The telescopic shaft of the electric push rod 9 drives the support frame 7 to move downward along the slot 6 until the outer surface of the pressure roller 8 contacts the upper surface of the aluminum plate. The straightening roller 5 and the pressure roller 8 contact the aluminum plate foil surface and generate pressure. Under continuous pressure, the bent part of the aluminum plate is gradually straightened.
