[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4 The utility model provides a technical solution: an adjustable aluminum plate extrusion machine, comprising: a first group of roller conveyor belts 1, the lower right end of the first group of roller conveyor belts 1 is connected to an extrusion roller base 2, the lower end of the extrusion roller base 2 is rotatably connected to a lower extrusion roller 3, a motor is installed inside the extrusion roller base 2, and the motor output end inside the extrusion roller base 2 is fixedly connected to one side of the lower extrusion roller 3, the upper surface of the extrusion roller base 2 is connected to a top cover 4 which is hollow inside and has openings on both sides, an upper extrusion roller 5 is arranged at a position opposite to the lower extrusion roller 3 inside the top cover 4, and an adjustment block 6 is rotatably connected to the front and rear ends of the upper extrusion roller 5, a limiting groove 7 is provided inside the front and rear ends of the top cover 4, and the adjustment block 6 is inserted and connected with the limiting groove 7, a hydraulic cylinder 8 is installed at a position opposite to the limiting groove 7 inside the roller base 2, the telescopic end on the upper side of the hydraulic cylinder 8 passes through the upper end of the extrusion roller base 2 and is fixedly connected to the lower surface of the adjustment block 6, and a second group of roller conveyor belts 9 is connected to the right side of the roller base 2.

[0024] When in use, start the hydraulic cylinder 8 inside the extrusion roller base 2, and the telescopic end of the hydraulic cylinder 8 will push the adjustment block 6 to adjust the height of the upper extrusion roller 5. The height of the upper extrusion roller 5 is adjusted to a height that is higher on the left side than on the right side. The distance between the upper extrusion roller 5 and the lower extrusion roller 3 on the right side is the same as the required height of the aluminum plate. Place the aluminum plate on the upper surface of the first group of roller conveyor belts 1, and then the aluminum plate will be transmitted to the inside of the extrusion roller base 2 by the first group of roller conveyor belts 1. Then the three groups of upper extrusion rollers 5 and lower extrusion rollers 3 will gradually increase pressure. After the thickness of the aluminum plate is extruded to the required thickness, it is discharged through the second group of roller conveyor belts 9.

[0025] like Figure 1-2 As shown, an embodiment of the utility model provides an implementation method, based on the above implementation method, a warping leveling shell 21 with a hollow upper end and openings on both left and right sides is connected to the right side of the second group of roller conveyor belts 9, and a lower leveling platform 22 is connected to the lower surface inside the cavity of the warping leveling shell 21, and an upper leveling platform 23 is arranged inside the cavity of the warping leveling shell 21 and at the upper end of the lower leveling platform 22, and a hydraulic press 24 is connected to the left and right sides of the upper surface of the warping leveling shell 21, and the lower telescopic end of the hydraulic press 24 passes through the upper end of the warping leveling shell 21 and is fixedly connected to the upper surface of the upper leveling platform 23, the protrusions and grooves of the lower leveling platform 22 and the upper leveling platform 23 are opposite to each other, and a third group of roller conveyor belts 25 is connected to the right side of the warping leveling shell 21.

[0026] From the analysis of the above structure, it can be known that after starting the two hydraulic presses 24 and adjusting the distance between the upper leveling platform 23 and the lower leveling platform 22, when the aluminum plate enters the interior, the warped positions will be gently guided and squeezed by the arc-shaped protrusions or depressions. After multiple squeezing, the set distance between the upper leveling platform 23 and the lower leveling platform 22 will be maintained, and then discharged through the third set of roller conveyor belts 25.

[0027] like Figure 1-2 As shown, an embodiment of the utility model provides an implementation method. Based on the above implementation method, the three rollers of the lower extrusion roller 3 have the same height, and the lower extrusion roller 3, the first group of roller conveyor belts 1, the second group of roller conveyor belts 9, and the third group of roller conveyor belts 25 are at the same height as the upper end of the lower leveling platform 22.

[0028] From the analysis of the above structure, it can be seen that during the transmission of the aluminum plate, the lower extrusion roller 3, the first group of roller conveyor belts 1, the second group of roller conveyor belts 9, and the third group of roller conveyor belts 25 are at the same height as the upper end of the lower leveling platform 22, which can ensure that the height of the aluminum plate will not change and will not bend during the extrusion process.

[0029] like Figure 1-2As shown, the embodiment of the utility model provides an implementation method. Based on the above implementation method, a fixed handle 26 is connected to the upper surface of the top cover 4 and located at the middle upper end of the adjustment block 6 through threads.

[0030] From the analysis of the above structure, it can be known that after the position of the upper extrusion roller 5 is adjusted, the fixed handle 26 is rotated to press the lower end of the fixed handle 26 against the upper surface of the adjustment block 6 to prevent the upper extrusion roller 5 from jumping upward during extrusion, thereby affecting the accuracy.

[0031] like Figure 1-4 As shown, an embodiment of the utility model provides an implementation method, based on the above implementation method, the second group of roller conveyor belts 9 and the third group of roller conveyor belts 25 are provided with T-shaped slide grooves 27 in an array at the upper ends thereof, and sliders 28 are inserted and connected inside the front and rear ends of the slide grooves 27, and a hollow correction roller 29 is provided at the upper end of the slider 28, and a bolt 30 is inserted and connected to the upper end of the correction roller 29, and the bolt 30 is threadedly connected to the lower end of the slider 28, and the upper and lower ends of the correction roller 29 are connected to plane bearings.

[0032] From the analysis of the above structure, it can be known that during installation, after the slider 28 is placed into the interior of the slide groove 27, it is rotated ninety degrees, and then the correction roller 29 is superimposed on the upper end of the slider 28, and the bolt 30 is inserted into the interior of the correction roller 29, and then rotated, and the bottom of the bolt 30 is pressed against the conveyor belt, and the slider 28 is adjusted to a state where the spacing on the left side is larger and the spacing on the right side is smaller. After the aluminum plate is extruded or leveled, it is transmitted to the upper surface of the second group of roller conveyor belts 9 and the third group of roller conveyor belts 25, and then the aluminum plate will hit the outside of the correction roller 29, and the correction roller 29 will rotate, so as to correct the position of the aluminum plate and prevent the position of the aluminum plate from shifting.

[0033] like Figure 1-2 As shown, an embodiment of the utility model provides an implementation method. Based on the above implementation method, the left and right sides of the front and rear ends of the first group of roller conveyor belts 1 are connected with safety gratings 31.

[0034] From the analysis of the above structure, it can be known that the safety grating 31 will form a sensing range within the front and rear ends of the left side of the extrusion roller base 2. When the operation is not standardized and debris falls into the detection range, the rotation of the first group of roller conveyor belts 1 will be stopped to prevent accidental injury to the user or debris from falling onto the surface of the aluminum plate.

[0035] like Figure 1-4 As shown, an embodiment of the utility model provides an implementation method. Based on the above implementation method, the outer surfaces of the rollers of the first group of roller conveyor belts 1, the second group of roller conveyor belts 9 and the third group of roller conveyor belts 25 are wrapped with rubber anti-slip pads.

[0036] Analysis of the above structure shows that when the roller rotates, the rubber anti-skid pad increases the resistance between the roller and the aluminum plate, preventing the rollers on the first group of roller conveyor belts 1, the second group of roller conveyor belts 9 and the third group of roller conveyor belts 25 from idling.

[0037] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
