[0032] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0033] See also Figures 1 to 8 In an embodiment of the present invention, a plate rolling machine with self-adjusting plate curling degree comprises a plate rolling seat 1, a limit box 2 is symmetrically installed on the upper end of the plate rolling seat 1, and the interior of the limit box 2 is a hollow box structure design, a limit shaft 7 is rotatably installed between the lower ends of the limit box 2, and an adjusting frame 8 is symmetrically installed at both ends of the limit shaft 7, and a clamping mechanism for limiting the feeding and discharging of the plate is arranged on the adjusting frame 8, so as to maintain a certain bending curvature of the plate when entering and exiting the plate rolling machine, and an adjusting mechanism is arranged inside the limit box 2, and the adjusting mechanism comprises a limit block 30 slidably arranged inside the limit box 2, and a working shaft 6 is rotatably installed between the limit blocks 30, and a working roller 5 is fixedly installed on the working shaft 6, and the adjusting mechanism also comprises an adjusting component for changing the position between the adjusting frames 8, so as to change the position of the plate when feeding and discharging, and finally adjust the bending degree of the plate rolling, and a transmission mechanism for driving the working roller 5 to rotate is arranged on one of the limit boxes 2, so as to provide a bending power source for the plate rolling action.

[0034] In one case of this embodiment, the clamping mechanism includes a plurality of balancing rollers 9 rotatably installed between adjustment frames 8, the adjustment frames 8 are provided with adjustment grooves 12, adjustment blocks 13 are slidably installed inside the adjustment grooves 12, balancing frames 10 are installed between the adjustment blocks 13, guide plates 18 are symmetrically fixedly installed at both ends of the balancing frames 10, guide rollers 11 are rotatably installed between the guide plates 18, and the clamping mechanism also includes a clamping assembly.

[0035] Among them, the clamping assembly includes a clamping shaft 15 slidably arranged at both ends of the balancing frame 10, the bottom of the clamping shaft 15 cooperates with a plurality of clamping holes 14 arranged on the upper side of the adjusting frame 8, and a clamping block 16 is fixedly installed on the top of the clamping shaft 15, and a clamping spring 17 is sleeved on the outer side of the clamping shaft 15 between the clamping block 16 and the balancing frame 10.

[0036] The working principle of the above-mentioned clamping mechanism is: when rolling the plate, the staff needs to pass the plate through the gap between the balance roller 9 and the guide roller 11, and then move the adjustment block 13 in the adjustment groove 12 as needed, and use the cooperation between the clamping shaft 15 and the clamping spring 17 to press the clamping shaft 15 into the clamping hole 14 at the corresponding position, so as to achieve the subsequent rolling processing of plates with different curvatures. The whole operation process is quick and convenient, and it is worthy of popularization and use.

[0037] In addition, in order to quickly adjust the angular position between the adjustment frames 8, in this embodiment, the adjustment assembly includes an adjustment screw shaft 29 vertically rotatably installed inside the limit box 2, and the adjustment screw shaft 29 and the limit block 30 cooperate with each other through a threaded structure. The limit block 30 has symmetrically fixedly installed clamping plates 31 at both ends, and the clamping plate 31 is hingedly installed with a clamping frame 32 through a clamping groove 33 set on the side wall of the limit box 2. The clamping frame 32 is hingedly installed on the adjustment frame 8 at one end away from the clamping plate 31.

[0038] At the same time, in order to ensure the normal power input of the adjustment mechanism, an adjustment motor 3 is fixedly installed on the upper end of the limit box 2, and the output end of the adjustment motor 3 is connected to the adjustment screw shaft 29. The side wall of the limit box 2 is also provided with a working groove 28 that cooperates with the working shaft 6.

[0039] The working principle of the above-mentioned adjustment component is: start the adjustment motor 3 to make the adjustment screw shaft 29 rotate, and then with the cooperation of the threaded structure, it is converted into an up and down linear movement of the limit block 30 inside the limit box 2. During the movement of the limit block 30, on the one hand, the position of the working roller 5 will also change accordingly, and on the other hand, with the cooperation of the clamping plate 31 and the clamping frame 32, the angle between the symmetrically arranged adjustment frames 8 will also change accordingly. When it is necessary to increase the rolling angle between the plates, the limit block 30 is moved downward, and at the same time, the two groups of adjustment frames 8 are also spread out to increase the rolling angle, finally realizing a rapid change in the bending degree of the plate rolling. When it is necessary to reduce the bending degree of the plate rolling, the adjustment motor 3 is started to reverse, and then the adjustment screw shaft 29 is rotated in the opposite direction.

[0040] In addition, in order to ensure that the working roller 5 can still maintain the self-rotation movement in the working state when the upper and lower positions change, in this embodiment, the transmission mechanism includes a working motor 4 fixed on the side wall of the limit box 2, and the output end of the working motor 4 is connected to the transmission shaft 19, and a transmission pulley 21 is fixedly installed on the end of the transmission shaft 19. The outer side of the transmission pulley 21 is connected to an intermediate pulley 25 through a transmission belt 24, and the intermediate pulley 25 is coaxially fixed with a connecting pulley 26. A working pulley 27 is installed on the outer side of the connecting pulley 26 through a working belt 23, and the working pulley 27 is fixed on the working shaft 6. The transmission mechanism also includes a transmission frame assembly.

[0041] In order to limit the positions of the above-mentioned multiple pulleys, in this embodiment, the transmission frame assembly includes a transmission frame 20 hingedly mounted on the transmission shaft 19 and a working frame 22 hingedly mounted on the working shaft 6. The working frame 22 and the other end of the transmission frame 20 are hingedly matched with each other, and a connecting pulley 26 and an intermediate pulley 25 are coaxially installed at the hinge position.

[0042] The working principle of the above-mentioned transmission mechanism is: in the process of the working motor 4 driving the transmission shaft 19 to rotate, the working shaft 6 is rotated through the cooperation between the above-mentioned multiple sets of pulleys. Even if the upper and lower positions of the working shaft 6 change, under the position restriction between the working frame 22 and the transmission frame 20, the torque of the transmission shaft 19 will still be transmitted to the working shaft 6.

[0043] In addition, in order to ensure the applicability of the plate rolling machine in plate rolling work, in this embodiment, the working motor 4 and the adjusting motor 3 are both double-steering stepping motors, so that the working roller 5 and the limit block 30 can move in both directions.

[0044] In addition, in order to ensure the effective position movement of the entire balancing frame 10 , in this embodiment, the adjustment block 13 is configured as an L-shaped structure, so that the installation connection of the balancing frame 10 can be better achieved.

[0045] In summary, when the plate is rolled, the in and out direction of the plate is first limited between the balance roller 9 and the guide roller 11 by the clamping mechanism, and then the adjusting motor 3 and the working motor 4 are started. On the one hand, the working roller 5 is rotated, and on the other hand, with the cooperation of the adjusting mechanism, the position of the adjusting frame 8 and the working roller 5 is changed, thereby automatically adjusting the curling degree of the plate to be rolled, meeting the needs of rolling plates with curling degrees at different angles.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
