SPECIFIC EMBODIMENTS

[0022] The following combines specific embodiments to illustrate the present utility model.

[0023] Embodiment 1, as Figures 1 to 3 shown, an improved leveling machine includes a frame 1, and the frame 1 is provided with a feeding pinch roller assembly 2 and a leveling assembly 3 arranged in sequence from front to back along the conveying direction of the metal plate. The feeding pinch roller assembly 2 includes an upper pinch roller 21 and a lower pinch roller 22, and the leveling assembly 3 includes an upper leveling roller group 31 and a lower leveling roller group 32.

[0024] Among them, as Figures 1 to 3 shown, an automatic material receiving assembly 4 is installed on the front side of the frame 1 of the feeding pinch roll assembly 2. The automatic material receiving assembly 4 includes a movable material receiving plate 41, a material receiving plate driving oil cylinder 42, and an oil cylinder hinge seat 43. The oil cylinder hinge seat 43 is fixedly installed on the frame 1. The rear end of the movable material receiving plate 41 is hinged to the frame 1 through a pivot. The material receiving plate driving oil cylinder 42 is located between the movable material receiving plate 41 and the oil cylinder hinge seat 43. The cylinder body of the material receiving plate driving oil cylinder 42 is hinged to the oil cylinder hinge seat 43 through a pivot, and the extended end of the piston rod of the material receiving plate driving oil cylinder 42 is hinged to the movable material receiving plate 41 through a pivot.

[0025] Furthermore, as Figure 1 and Figure 2 shown, the automatic material receiving assembly 4 further includes a pressing driving oil cylinder 44 that is fixedly installed on the frame 1 and moves vertically. The pressing driving oil cylinder 44 is located above the movable material receiving plate 41. The extended end of the piston rod of the pressing driving oil cylinder 44 is provided with a pressing movable seat 45, and a pressing roller 46 is rotatably installed on the pressing movable seat 45.

[0026] When the automatic material receiving assembly 4 in the first embodiment works, the material receiving plate driving oil cylinder 42 drives the movable material receiving plate 41 to rotate, so that the metal sheet sent out by the uncoiler falls onto the movable material receiving plate 41. During this process, the pressing driving oil cylinder 44 drives the pressing movable seat 45 to move downward. The pressing movable seat 45 that moves downward drives the pressing roller 46 to move downward synchronously, so that the pressing roller 46 presses downward on the metal sheet that has fallen onto the movable material receiving plate 41. As the uncoiler continuously sends out the metal sheet, the pressing roller 46 cooperates with the movable material receiving plate 41 and guides the head of the metal sheet between the upper pinch roll 21 and the lower pinch roll 22 of the feeding pinch roll assembly 2, thereby enabling the metal sheet to accurately and quickly enter the feeding pinch roll assembly 2.

[0027] It should be noted that the material receiving plate driving oil cylinder 42 drives the movable material receiving plate 41 to perform a rotating action, so that the inclination angle of the movable material receiving plate 41 adapts to the angle of the metal sheet sent out by the uncoiler.

[0028] Based on the above situation, it can be seen that through the above structural design, the improved leveling machine in the first embodiment has the advantages of novel structural design, can realize automatic auxiliary material receiving, and can enable the metal sheet to accurately and quickly enter the feeding pinch roll assembly 2.

[0029] Embodiment 2, as Figure 2 and Figure 2 shown, the difference between the second embodiment and the first embodiment is that a movable telescopic plate 47 is slidably installed on the movable material receiving plate 41, and a telescopic driving oil cylinder 48 is installed on the movable material receiving plate 41 corresponding to the movable telescopic plate 47. The extended end of the piston rod of the telescopic driving oil cylinder 48 is connected to the movable telescopic plate 47.

[0030] Among them, to ensure that the movable telescopic plate 47 can accurately perform telescopic movement relative to the movable material receiving plate 41, the following guiding structure design is adopted in the second embodiment. Specifically: telescopic plate guiding parts are respectively arranged at the left end edge part and the right end edge part of the movable telescopic plate 47, and telescopic sliding grooves (not shown in the figure) are respectively formed in the movable material receiving plate 41 corresponding to the telescopic plate guiding parts, and the telescopic plate guiding parts are respectively slidably installed in the telescopic sliding grooves on the corresponding sides.

[0031] When the improved leveling machine in the second embodiment works, the telescopic driving oil cylinder 48 drives the movable telescopic plate 47 to perform telescopic movement relative to the movable material receiving plate 41. When the movable telescopic plate 47 extends from the movable material receiving plate 41, the overall receiving length of the receiving plate structure composed of the movable material receiving plate 41 and the movable telescopic plate 47 becomes larger; when the movable telescopic plate 47 retracts from the movable material receiving plate 41, the overall receiving length of the receiving plate structure composed of the movable material receiving plate 41 and the movable telescopic plate 47 becomes smaller; therefore, the second embodiment can adaptively adjust the receiving length according to the diameter of the metal sheet coil on the uncoiler.

[0032] Embodiment Three, as Figure 1 and Figure 2 shown, the difference between the third embodiment and the first embodiment is that: a cantilever seat 11 protruding forward is provided at the upper end of the frame 1, and the pressing driving oil cylinder 44 is screwed and fastened to the cantilever seat 11.

[0033] Embodiment Four, as Figure 1 and Figure 2 shown, the difference between the fourth embodiment and the first embodiment is that: a vertically acting lifting driving oil cylinder 23 is fixedly installed above the upper end pinch roller 21 on the frame 1, an extension end of the piston rod of the lifting driving oil cylinder 23 is provided with a lifting movable seat 24, and the upper end pinch roller 21 is rotatably installed on the lifting movable seat 24.

[0034] Among them, the lower end pinch roller 22 is located below the upper end pinch roller 21, and the lower end pinch roller 22 is rotatably installed on the frame 1.

[0035] During the working process of the feeding pinch roller assembly 2 in the fifth embodiment, before the head of the metal sheet enters, the lifting driving oil cylinder 23 drives the lifting movable seat 24 and the upper end pinch roller 21 to move upward, so that there is a larger metal sheet entering gap between the upper end pinch roller 21 and the lower end pinch roller 22; after the metal sheet enters between the upper end pinch roller 21 and the lower end pinch roller 22, the lifting driving oil cylinder 23 acts and drives the lifting movable seat 24 and the upper end pinch roller 21 to move downward, so that the upper end pinch roller 21 moves down to the pinch operation position.

[0036] The above content is only a preferred embodiment of the present utility model. For those of ordinary skill in the art, based on the idea of the present utility model, there will be changes in the specific implementation manner and application scope. The content of this specification should not be construed as a limitation to the present utility model.
