Description

Technical Field

[0001] This invention relates to the field of leveling machine technology, specifically to an unwinding leveling machine with protective functions and its usage method. Background Technology

[0002] A leveling machine is a device used to level sheet materials. When using roll materials, they need to be leveled to make the surface of the roll material flat. After leveling, the sheet materials usually need to be transported to other places for storage. Some thin sheets need to be prevented from bending under gravity after leveling. Therefore, a support device is needed at the discharge end of the leveling machine to support the sheet materials. The support device also occupies a certain amount of space.

[0003] The shortcomings of existing leveling machines are:

[0004] 1. The prior art EP2934780A1 discloses a straightening machine, which does not have a structure to support the straightened and discharged product. It requires manual support or the use of other support equipment to support the sheet material, which is cumbersome. Therefore, there is a need for an uncoiling and leveling machine with protective function to support the straightened and discharged sheet material to solve this problem.

[0005] 2. The prior art US07543470B2 discloses a coil straightening machine. This technology does not have a structure to detect whether there are obstacles in the direction of material discharge. If there are obstacles in the direction of material discharge, the material will collide with the obstacles, causing damage to the obstacles or the material. Therefore, there is a need for an uncoiling and leveling machine with protective function that can detect whether there are obstacles in the direction of material discharge and stop material discharge when there are obstacles to solve this problem.

[0006] 3. The prior art US20070062239A1 discloses a coil straightening machine. This technology does not have a structure for transporting the leveled sheet material to a transport device. The transport requires manual handling, which consumes physical strength and the sheet material is easily scratched by friction with other objects. Therefore, an uncoiling and leveling machine with protective functions is needed to solve this problem.

[0007] 4. The prior art CN115673037B discloses an adjustable leveling machine. This technology does not have a structure to transport the leveled board to other places. When people are transporting the board, there is a chance of collision with the board or auxiliary transport equipment, which can easily cause injury to personnel. Therefore, there is a need for an uncoiling leveling machine with transport function and protective function to reduce collision damage to solve this problem. Summary of the Invention

This allows the uncoiling and leveling machine with protective function to detect the pressure of the sheet metal on the detection plate through the pressure sensing unit. When the pressure increases, the second hydraulic telescopic unit drives the travel plate forward, and at the same time, the second frame moves upward to support the sheet metal with the top wheel.

This ensures that the uncoiling and leveling machine with protective function stops moving forward when the laser ranging unit detects an obstacle ahead, thus preventing collisions with pedestrians.

[0028] 3. The present invention is provided with a transport mechanism. The transport frame clamps the sheet metal and then the transport frame moves the sheet metal to the transport equipment on both sides or in front.

The unwinding and leveling machine with protective function according to claim 1, characterized in that: A plate (7) is installed on the back of the frame (1), and a placement plate (8) is symmetrically installed on the top of the plate (7). A unwinding roller (9) is movably installed through the top of the placement plate (8).

3. The unwinding and leveling machine with protective function according to claim 2, characterized in that: Multiple pressure sensing units (19) are symmetrically installed on the back of the baffle (17). The pressure sensing units (19) are electrically connected to the control module (6). A detection plate (20) is installed at the input end of the pressure sensing unit (19).

4. The method of using an unwinding and leveling machine with protective function according to claim 3, characterized in that: The method of using the unwinding and leveling machine with protective function is as follows: S1. Place the roll material outside the unwinding roller (9), and then let one end of the roll material enter the interior of the leveling roller one (3) and the leveling roller two (4) for leveling. The leveled material is in contact with the detection plate (20). S2, As the plate moves forward, the frame (13) moves upward in sequence, so that the top wheel (14) supports the plate. S3. When the laser ranging unit (18) detects an obstacle in front, the travel plate (11) and the leveling plate stop moving forward. S4. After leveling, the transport frame (34) clamps the plate and then the transport frame (34) moves the plate to the transport equipment on both sides or in front.

5. The method of using an unwinding and leveling machine with protective function according to claim 4, characterized in that: The S4 process also includes the following steps: S41. When the transport frame (34) moves the board, the sponge (38) protects the personnel and prevents the frame (37) from directly colliding with the personnel and causing injury.
