Description

Technical Field

[0001] The utility model relates to the field of license plate production tools, in particular to a motor vehicle license plate material leveling device. Background Art

[0002] The leveling machine is also called a leveling machine, a flat plate machine, a leveling machine, a correcting machine, and a straightening machine. The leveling machine is mainly used to correct various specifications of plates and plates cut into blocks. This machine is suitable for the leveling of various cold-rolled and hot-rolled plates. The plates made into motor vehicle license plates also need to be leveled. During leveling, the plates are passed through two sets of upper and lower correction rollers with staggered distributions in sequence, and the "Bauschinger effect" of the material is used to bend the plates repeatedly many times, gradually reducing the bending deflection, so that the multiple original curvatures gradually become a single curvature, and finally leveled to achieve the flatness accuracy required by the process.

[0003] When the leveling machine is in use, the plate is fed into two sets of correction rollers, and the plate needs to be kept in a straightened state, so that when the correction fails and needs to be re-corrected, the plate is aligned with the direction in which it was first inserted into the correction roller, so that the axis direction of the plate is consistent with the forward direction of the plate, and the position where the plate correction fails can be successfully corrected in the second correction. Often in the process of use, the direction of the plate obliquely inserted into the correction roller is difficult to grasp. During the second correction, there is always a deviation between the direction of the reinserted correction roller and the direction of the first insertion, so that the plate cannot be corrected for the second time. Summary of the invention

[0004] The technical problem to be solved by the utility model is: when the leveling machine is in use, the plate is fed into two sets of correction rollers, and the plate needs to be kept in a straightened state, so as to ensure that when the correction is unsuccessful and needs to be re-corrected, the plate is aligned with the direction in which it was initially inserted into the correction rollers, so that the axis direction of the plate is consistent with the forward direction of the plate, and it is ensured that the position where the plate correction failed can be successfully corrected in the second correction. Often in the process of use, the direction of the plate obliquely inserted into the correction rollers is difficult to grasp, and during the second correction, there is always a deviation between the direction of the reinserted correction rollers and the direction of the initial insertion, so that the plate cannot be corrected for the second time.

[0005] In order to solve the above problems, the technical solution adopted by the utility model is: a motor vehicle license plate material leveling device, including a working box and two groups of correction rollers rotatably arranged in the middle of the working box for correcting the flatness of the license plate plate, the working box is equipped with a built-in driving mechanism for driving the two groups of correction rollers to rotate, an installation box is provided on the top of one side of the working box, and an auxiliary component for straightening the license plate plate is provided at the bottom of the installation box.

[0006] The beneficial effects of the utility model are as follows: the auxiliary component capable of straightening the license plate plate is used in conjunction with the correction roller, so that the axial direction of each plate inserted into the correction roller is consistent with the forward direction of the plate, preparing for possible secondary correction and improving the efficiency of plate correction.

[0007] As a further improvement of the present invention, the technical problem to be solved is: how to straighten the plate specifically.

[0008] In order to solve the above technical problems, the utility model further improves the technical solution adopted as follows: the auxiliary component includes two transmission plates arranged at the bottom of the installation box for mirror movement, a mounting frame arranged on the opposite side of the two transmission plates, and a plurality of alignment rotating blocks rotatably arranged in the installation frame for aligning the license plate plate. A transmission component for transmission of the two transmission plates is provided in the installation box, and a circle of pressure sensors is embedded on the circumference of the bottom of the alignment rotating block.

[0009] The beneficial effect of the above improvement is: the auxiliary assembly consisting of the transmission plate, the mounting frame and the alignment rotary block is used to perform the straightening operation on the license plate plate to be inserted into the correction roller, so that the two transmission plates moving relative to each other carry the corresponding alignment rotary blocks gradually approach the side of the license plate plate until they are close to the license plate plate, so that the pressure sensors on the alignment rotary blocks on the same side are subjected to the same pressure, thereby achieving the effect of straightening the license plate plate.

[0010] The utility model further improves the technical solution adopted as follows: a workbench for placing the license plate plate is provided on one side of the working box below the installation box, and the bottom surfaces of the installation frame and the alignment rotating block are both in contact with the workbench.

[0011] The beneficial effect of the above improvement is: ensuring that the alignment rotating block can be against the side edge of the license plate plate placed on the workbench.

[0012] The utility model further improves the technical solution adopted as follows: a spring telescopic rod is arranged between the transmission plate and the corresponding installation frame.

[0013] The beneficial effect of the above improvement is: the spring telescopic rod is used to reduce the hard squeezing force of the transmission plate with the alignment rotary block when it abuts the license plate plate, so that when the alignment rotary block first abuts the side of the license plate plate, the spring telescopic rod is squeezed to make it expand and contract, while the transmission plate is still moving at this time. The abutting force of the alignment rotary block on the license plate plate will not cause deformation of the license plate plate until the pressure sensor on the alignment rotary block on the same side is subjected to the same pressure and is fed back to the transmission assembly to stop the movement of the transmission plate.

[0014] The technical solution further improved by the utility model is as follows: a plurality of sliding-assisting rollers are rollingly embedded in the bottom surface of the installation frame, the rolling direction of the sliding-assisting rollers is the same as the moving direction of the corresponding transmission plates, the bottom surface of the alignment rotating block is embedded with sliding-assisting balls, and the top surface of the workbench is respectively provided with a slide groove 1 and a slide groove 2 for cooperating with the sliding-assisting rollers and the sliding-assisting balls.

[0015] As a further improvement of the utility model, the technical problem to be solved is: how to realize the synchronous relative rotation of the two transmission plates to drive the alignment rotating block on the same side to realize the straightening operation of the license plate plate.

[0016] In order to solve the above technical problems, the utility model further improves the technical solution adopted as follows: the transmission assembly includes a bidirectional screw rotatably arranged in an installation box and a threaded seat slidably sleeved on both ends of the bidirectional screw, a guide groove is opened at the bottom of the installation box, the top of the transmission plate is fixedly connected to the bottom of the threaded seat, an external motor for driving the bidirectional screw to rotate is installed outside the installation box, the output end of the pressure sensor is electrically connected to the input end of the processor, the output end of the processor is electrically connected to the input end of the relay, and the output end of the relay is electrically connected to the external motor.

[0017] The beneficial effect of the above improvement is: using an external motor to rotate the bidirectional screw, and then driving the two threaded seats on the bidirectional screw to move relative to each other, so as to control the relative movement of the two transmission plates to realize the function of aligning the rotating block against the license plate plate for correction.

DETAILED DESCRIPTION

[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the protection scope of the present invention.

[0024] Embodiment 1:

[0025] like Figure 1-4 As shown, a motor vehicle license plate material leveling device comprises a working box 1 and two groups of correction rollers 2 for correcting the flatness of the license plate plate rotatably arranged in the middle of the working box 1, a built-in driving mechanism for driving the two groups of correction rollers 2 to rotate is installed in the working box 1, a mounting box 3 is arranged on the top of one side of the working box 1, and an auxiliary component for straightening the license plate plate is arranged at the bottom of the mounting box 3. The auxiliary component comprises two transmission plates 5 arranged at the bottom of the mounting box 3 in a mirror-image manner, a mounting frame 6 arranged on the opposite side of the two transmission plates 5, and a plurality of alignment rotating blocks 7 rotatably arranged in the mounting frame 6 for straightening against the license plate plate, a transmission component for the transmission of the two transmission plates 5 is arranged in the mounting box 3, and a circle of pressure sensors are embedded around the bottom of the alignment rotating block 7. A working table 4 for placing the license plate plate is arranged on one side of the working box 1 below the mounting box 3, and the bottom surfaces of the mounting frame 6 and the alignment rotating block 7 are both in contact with the working table 4. A spring telescopic rod 8 is arranged between the transmission plate 5 and the corresponding mounting frame 6. A plurality of sliding aid rollers 9 are rotatably embedded in the bottom surface of the installation frame 6, and the rolling direction of the sliding aid rollers 9 is the same as the moving direction of the corresponding transmission plate 5. The bottom surface of the alignment rotating block 7 is embedded with sliding aid balls 10. The top surface of the workbench 4 is provided with a slide groove 1 and a slide groove 2 for cooperating with the sliding aid rollers 9 and the sliding aid balls 10. The transmission assembly includes a bidirectional lead screw 11 rotatably arranged in the installation box 3 and a threaded seat 12 slidably sleeved at both ends of the bidirectional lead screw 11. A guide groove is provided at the bottom of the installation box 3. The top of the transmission plate 5 is fixedly connected to the bottom of the threaded seat 12. An external motor for driving the bidirectional lead screw 11 to rotate is installed outside the installation box 3. The output end of the pressure sensor is electrically connected to the input end of the processor, the output end of the processor is electrically connected to the input end of the relay, and the output end of the relay is electrically connected to the external motor.

[0026] The auxiliary component capable of aligning the license plate is used in conjunction with the correction roller 2, so that the axial direction of each plate inserted into the correction roller 2 is consistent with the plate's forward direction, preparing for possible secondary correction and improving the efficiency of plate correction. The auxiliary component consisting of the transmission plate 5, the mounting frame 6 and the alignment turn block 7 is used to align the license plate to be inserted into the correction roller 2, so that the two transmission plates 5 moving in opposite directions with the corresponding alignment turn blocks 7 gradually approach the side of the license plate until they are close to the license plate, so that the pressure sensors on the alignment turn blocks 7 on the same side are subjected to the same pressure, thus realizing the function of aligning the license plate. Ensure that the alignment turn block 7 can rest against the side of the license plate placed on the workbench 4. The spring telescopic rod 8 is used to reduce the rigid squeezing force of the transmission plate 5 with the alignment rotating block 7 against the license plate sheet, so that when the alignment rotating block 7 first abuts against the side of the license plate sheet, the spring telescopic rod 8 is squeezed to make it expand and contract, while the transmission plate 5 is still moving at this time. The contact force of the alignment rotating block 7 against the license plate sheet will not cause the license plate sheet to deform thereafter, until the pressure sensor on the alignment rotating block 7 on the same side is subjected to the same pressure, which is fed back to the transmission assembly to stop the movement of the transmission plate 5. By using the cooperation between the sliding roller 9 and the first slideway and the cooperation between the sliding ball 10 and the second slideway, when the transmission plate 5 moves with the corresponding side alignment rotating block 7, the friction between the sliding roller 9 and the sliding ball 10 and the workbench 4 is reduced. At the same time, when the straightened license plate sheet is inserted into the correction roller 2, the alignment rotating block 7 rotates in the forward direction of the license plate sheet, and the sliding ball 10 reduces the friction when the alignment rotating block 7 rotates, reducing the resistance of the license plate sheet inserted into the correction roller 2. An external motor is used to rotate the bidirectional lead screw 11, and then the two threaded seats 12 on the bidirectional lead screw 11 move relative to each other, so as to control the relative movement of the two transmission plates 5 to realize the effect of the alignment turn block 7 abutting against the license plate plate for correction. When the pressure sensor on the alignment turn block 7 is squeezed and triggered, the pressure sensor transmits the signal to the processor for processing. When the pressure sensors on the alignment turn block 7 on the same side are subjected to the same pressure, the processor sends a command to the external motor to stop.
