[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-7 This utility model provides a technical solution: an automatic plate rolling machine, comprising:

[0029] Countertop 1;

[0030] A rolling mechanism 2 for rolling metal sheets is installed on the top of the tabletop 1. The rolling mechanism 2 includes a base 21 fixedly installed on the top of the tabletop 1. A metal roller 22 is rotatably installed on one side of the base 21. A mounting seat 23 is provided on the top of the tabletop 1. A pressure roller 25 with a surface covered with an adhesive layer ring 24 is rotatably installed inside the mounting seat 23. A driving component 20 for driving the pressure roller 25 to press down and rotate is provided on the surface of the mounting seat 23. The pressure roller 25 is located on top of the metal roller 22.

[0031] A feeding mechanism 3 for conveying metal sheets to the rolling mechanism 2 is installed on the top of the table 1;

[0032] Specifically, the feeding mechanism 3 automatically conveys the metal sheet through the conveyor belt 35 and the motor 36. The guiding mechanism 9 can automatically adjust the position of the sheet. The surface of the pressure roller 25 is covered with a rubber ring 24 to avoid scratching the sheet. At the same time, the driving component 20 precisely controls the downward pressure, resulting in good forming consistency. The unloading mechanism 4 pushes the support plate 42 and the push plate 44 through the cylinder 41 to automatically push the formed coil away from the metal roller 22 and guides it out through the inclined unloading frame 7, reducing the risk of manual operation. It integrates the functions of feeding, coiling and unloading into one, saving space. The adjustable guiding mechanism 9 adapts to the processing needs of sheets of different sizes.

[0033] In this embodiment, the metal sheet is placed on the conveyor belt 35 of the feeding mechanism 3. The conveyor belt 35 is driven by the rod 33 driven by the motor 36. The rotation of the rod 33 drives the roller 34 to rotate, ultimately realizing the rotation of the conveyor belt 35 and conveying it towards the rolling mechanism 2. The two electric push rods 91 are synchronous push rods, adjusting the position of the pushers 92 on both sides according to the width of the sheet to ensure that the sheet enters the rolling mechanism 2 in the center and avoids deviation. The sheet is conveyed between the metal roller 22 and the pressure roller 25 of the rolling mechanism 2. The hydraulic rod 203 is activated to push the mounting base 23 down, so that the pressure roller 25 is pressed tightly against the sheet and applies pressure. At the same time, the driver 205 drives the pressure roller 25 to rotate, and the metal roller 22 rotates passively and cooperates with the pressure roller 25, so that the sheet gradually bends between the two to form the required cylindrical structure. The surface of the pressure roller 25 The adhesive ring 24 on the surface can prevent scratches on the sheet material surface and improve the forming quality. After the sheet is rolled, the cylinder 41 in the unloading mechanism 4 pushes the support plate 42 to move, so that one end of the metal roller 22 is detached from the support. The support of one end of the metal roller 22 is kept stable by the bearing 43 in the round hole 45. The push plate 44, driven by the slide plate 11, pushes the formed sheet away from the metal roller 22 and slides out along the inclined unloading frame 7 to complete the automatic unloading. After the unloading is completed, the cylinder 41 retracts, the support plate 42 is reset, and the metal roller 22 is fixed again to prepare for the next round of sheet rolling operation. The loading mechanism 3 continues to transport new sheet materials and repeats the above process to achieve continuous automated production. The adhesive ring 24 is made of a highly elastic composite material, which significantly improves production efficiency through automated loading, rolling and unloading processes.

[0034] The drive unit 20 includes two small plates 201 fixedly mounted on the surface of the mounting base 23. A large plate 202 is rotatably mounted on the surface of each of the two small plates 201. The bottom of each of the two large plates 202 is fixedly mounted on the top of the table 1 by bolts. A hydraulic rod 203 is hinged to the top of the table 1. The hydraulic rod 203 is used to move the pressure roller 25 downward and squeeze the metal plate on the top of the metal roller 22. A push plate 204 is hinged to the extended end of the hydraulic rod 203. The push plate 204 is fixedly mounted on the surface of the mounting base 23. A driver 205 for rotating the pressure roller 25 is mounted on one side of the mounting base 23.

[0035] Furthermore, the drive component 20 is mainly used to control the downward pressing, return, and rotational movement of the pressure roller 25. The hydraulic rod 203, hinged to the table 1, extends and pushes the push plate 204 downward. Since the push plate 204 is fixed on the mounting base 23, the mounting base 23 descends accordingly, causing the pressure roller 25 to approach the metal roller 22. The mounting base 23 achieves smooth downward pressing through the rotational connection of the small plate 201 and the large plate 202. After the pressure roller 25 contacts the metal sheet, the hydraulic rod 203 continues to apply pressure, causing the sheet to undergo plastic deformation between the metal roller 22 and the pressure roller 25, gradually... During bending and forming, while the pressure roller 25 presses down, the driver 205 drives the pressure roller 25 to rotate. The metal roller 22 is a passive roller, which rotates along with the plate under the action of the plate friction, so that the plate is continuously fed and evenly rolled. The rubber ring 24 on the surface of the pressure roller 25 can increase the friction and protect the plate surface from scratches. The hydraulic system has an overload protection function to prevent equipment damage caused by excessive plate thickness or hardness. The driver 205 directly drives the pressure roller 25 to rotate, reducing transmission loss and improving plate rolling efficiency. Moreover, this drive component 20 is particularly suitable for small and medium-sized plate rolling machines.

[0036] The top of the table 1 is provided with a feeding mechanism 4 for feeding the formed roll plate. The feeding mechanism 4 includes a cylinder 41 fixedly installed on the top of the table 1. The extended end of the cylinder 41 is fixedly installed with a horizontally movable support plate 42. The inside of the support plate 42 is provided with a round hole 45 for auxiliary support of the metal roller 22. The inside of the round hole 45 is provided with a bearing 43 that cooperates with the end of the metal roller 22. The bottom of the support plate 42 is fixedly installed with a sliding plate 11. The top of the sliding plate 11 is fixedly installed with a lever 44 for actuating the feeding of the formed roll plate. The lever 44 is located on one side of the metal roller 22.

[0037] It should be noted that, under normal operating conditions, one end of the metal roller 22 is provided with auxiliary support by the bearing 43 in the circular hole 45 of the support plate 42, ensuring that the metal roller 22 rotates stably during the rolling process. When the rolled plate is formed, the cylinder 41 is activated, pushing the support plate 42 to move horizontally, causing the end of the metal roller 22 to disengage from the bearing 43, thus releasing the support for the metal roller 22. When the support plate 42 moves, it drives the slide plate 11 at its bottom to move synchronously. The push plate 44 at the top of the slide plate 11 then moves towards the metal roller 22, contacting and pushing the rolled plate, causing it to disengage from the metal roller 22. After disengagement, the rolled plate slides to the designated collection position or conveyor belt 35 with the help of the inclined unloading rack 7. Automated unloading reduces manual operation and lowers the risk of workplace injuries.

[0038] Both sides of the slide plate 11 are provided with slide grooves 5, and slide rails 6 are slidably installed inside the two slide grooves 5. The bottom of the two slide rails 6 is fixedly installed on the top of the table 1, and the top of the two slide rails 6 is integrally machined with a dustproof plate.

[0039] Furthermore, the slide groove 5 and the slide rail 6 cooperate to form a precision guide mechanism 9, ensuring that the slide plate 11 moves horizontally along a fixed path under the push of the cylinder 41, avoiding deviation or jamming. The integrally formed dustproof plate covers the opening of the slide groove 5, effectively blocking metal dust and debris from entering the sliding mating surface, preventing impurities from wearing the inner wall of the slide groove 5, and extending its service life.

[0040] An inclined unloading rack 7 for guiding and conveying the formed roll is fixedly installed on the top of the slide plate 11, and a guide plate 8 for cooperating with the unloading rack 7 is fixedly installed on the top of the table 1.

[0041] When the formed coil is pushed away from the metal roller 22 by the push plate 44, it naturally falls into the inclined unloading frame 7 due to its own weight. The inclination angle of the unloading frame 7 ensures that the coil obtains initial downward acceleration.

[0042] The feeding mechanism 3 includes a frame 31 fixedly installed on the top of the table 1 by four columns. Two long plates 32 are fixedly installed on the bottom of the inner wall of the frame 31. Several rods 33 are rotatably installed between the two long plates 32. Rollers 34 are fixedly installed on the surface of each of the rods 33. Conveyor belts 35 are installed on the surface of each of the rollers 34. A motor 36 for rotating the rods 33 is provided on one side of the long plate 32.

[0043] It should be noted that the starting motor 36 drives the rod 33 to rotate, the rod 33 drives the surface roller 34 to rotate, and the surface friction of the roller 34 drives the conveyor belt 35 to move, providing automatic feeding operation for the metal sheet.

[0044] The frame 31 is provided with a guide mechanism 9 for arranging the metal sheets on the surface of the feeding mechanism 3. The guide mechanism 9 includes electric push rods 91 embedded on both sides of the frame 31. Push frame 92 is fixedly installed at the adjacent end of the two electric push rods 91. Guide cylinder 93 is rotatably installed inside the two push frame 92 through several limit rods.

[0045] It is worth noting that the two electric push rods 91 move synchronously towards each other, pushing the push frame 92 to move. When the push frame 92 moves and the plate enters, the guide cylinder 93 contacts the plate and rotates under the action of friction, thereby reducing the friction. In order to achieve synchronous operation of the two electric push rods 91, a Siemens S7-1200 controller is selected. The drive module is configured with a Delta ASD-B2 series dual-channel servo driver. The feedback system is an absolute encoder integrated in each push rod.

[0046] Two auxiliary rods 10 are fixedly installed on one side of the push frame 92, and the surfaces of the two auxiliary rods 10 are slidably installed with the inside of the frame 31;

[0047] An auxiliary rod 10 is positioned on one side of the pusher 92 and slides within the frame 31, providing guidance for the movement of the pusher 92.

[0048] The metal sheet is placed on the conveyor belt 35 of the feeding mechanism 3. The conveyor belt 35 is driven by the rod 33 by the motor 36. The rotation of the rod 33 drives the roller 34 to rotate, ultimately realizing the rotation of the conveyor belt 35 and conveying it towards the rolling mechanism 2. The two electric push rods 91 are synchronous push rods, adjusting the position of the pushers 92 on both sides according to the width of the sheet to ensure that the sheet enters the rolling mechanism 2 in the center. The sheet is conveyed between the metal roller 22 and the pressure roller 25 of the rolling mechanism 2. The hydraulic rod 203 is activated to push the mounting base 23 down, so that the pressure roller 25 is pressed tightly against the sheet and applies pressure. The driver 205 drives the pressure roller 25 to rotate, and the metal roller 22 rotates passively and cooperates with the pressure roller 25 to gradually bend the plate between the two to form the required cylindrical structure. After the plate is formed, the cylinder 41 in the unloading mechanism 4 pushes the support plate 42 to move, so that one end of the metal roller 22 is detached from the support. The pusher plate 44, driven by the slide plate 11, pushes the formed plate off the metal roller 22 and slides out along the inclined unloading frame 7 to complete the automatic unloading. After the unloading is completed, the cylinder 41 retracts, the support plate 42 is reset, and the metal roller 22 is fixed again to prepare for the next round of plate rolling operation.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
