DETAILED DESCRIPTION
[0018] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0019] like Figure 1 As shown in FIG. 2 , an embodiment of the utility model proposes a three-roller plate rolling machine, comprising a base 1, an upper roller 5, a limit plate 7 and a guide assembly, both ends of the base 1 are vertically provided with mounting plates 2, two lower rollers 3 are rotatably provided between the two mounting plates 2, and a first motor 4 for driving the lower roller 3 to rotate is embedded on one of the mounting plates 2; mounting grooves are provided on the two mounting plates 2, and sliders 6 are provided in the two mounting grooves, and the two ends of the upper roller 5 are respectively connected to the two sliders 6, and a lifting assembly for driving the corresponding slider 6 to rise and fall in the mounting groove is provided on the top of one of the mounting plates 2; there are two limit plates 7, and the two limit plates 7 are slidably arranged on the top of the base 1, and the two mounting plates 2 are also provided with a driving assembly for driving the two limit plates 7 to move toward or away from each other; the guide assembly is arranged on one side of the two mounting plates 2, and the guide assembly is used to guide the entry angle of the plate. During operation, the two limit plates 7 are first driven to move by the driving assembly so that the spacing between the limit plates 7 is the same as the width of the plate to be curled, and then the plate is placed between the upper roller 5 and the lower roller 3 from the side of the device with the guide assembly. In the present embodiment, there are two first motors 4, and the two first motors 4 are respectively connected to the corresponding lower rollers 3. The two lower rollers 3 rotate under the drive of the first motor 4, so as to bend and roll the plate into a roll. In this process, the guide assembly supports the plate, so that the entry angle of the plate does not change significantly, and also reduces the workload of the workers when slowly placing the plate into the device. When the plate is rolled, the two limit plates 7 limit the plate, avoiding the misalignment and distortion of the closing position after the plate is offset, thereby ensuring the quality of the roll after the rolling is formed and reducing the burden of subsequent processes.
[0020] like Figure 1 —3, further, the driving assembly includes: a bidirectional screw 8 and a second motor 9, the two ends of the bidirectional screw 8 are respectively threadedly connected to the two limit plates 7, the second motor 9 is embedded in one of the mounting plates 2, and the output end of the second motor 9 is fixedly connected to one end of the bidirectional screw 8. When the spacing between the two limit plates 7 is adjusted, the second motor 9 is started, and the second motor 9 drives the bidirectional screw 8 to rotate. The two ends of the two limit plates 7 are respectively threadedly connected to the two ends of the bidirectional screw 8, so that the two limit plates 7 are driven by the bidirectional screw 8 to move toward or away from each other, thereby limiting the moving space of the plate to prevent the plate from being offset when being bent into a roll. It should be noted that the two limit plates 7 are not in contact with the upper roller 5 and the lower roller 3, so as to prevent them from being driven by the lower roller 3 or affecting the removal of the formed roll.
[0021] like Figure 2 As shown, further, a first guide rod 10 is horizontally provided between the two mounting plates 2, and the first guide rod 10 is slidably connected to the two limit plates 7. The first guide rod 10 guides the movement of the two limit plates 7, so that the movement of the two limit plates 7 when approaching or moving away from each other is more stable.
[0022] like Figure 1 —3, further, the guide assembly includes: a guide plate 11 and a retractable assembly, the guide plate 11 is hingedly arranged on the side walls of the two mounting plates 2, the retractable assembly is arranged on the free end of the guide plate 11, and the side walls of the two mounting plates 2 are provided with steel wire ropes 12, and the end of each steel wire rope 12 away from the guide plate 11 is connected to the retractable assembly, and the retractable assembly is used to roll or release the steel wire rope 12. When the plate is bent into a roll, the inclination angle of the guide plate 11 is adjusted by the retractable assembly, and then the end of the plate that has not been bent is placed on the guide plate 11. The worker only needs to push the plate into between the upper roller 5 and the two lower rollers 3, saving physical strength.
[0023] like Figure 4As shown, further, the retracting and releasing components all include: a retracting rod 13, a groove 14 is provided on the free end of the guide plate 11, and both ends of the groove 14 are provided with internal threads, and both ends of the retracting rod 13 are threadedly connected with both ends of the groove 14, and the end of the wire rope 12 away from the mounting plate 2 penetrates into the groove 14 and then rolls up on the retracting rod 13. In this embodiment, the groove 14 is a structure with thin ends and thick middle, and the internal threads at both ends of the groove 14 are threadedly connected with the retracting rod 13, and the middle part of the groove 14 is for receiving the wire rope 12. When the wire rope 12 is rolled up or released, the retracting rod 13 is rotated, and the retracting rod 13 can roll up or release the wire rope 12 when it is rotated, so that the angle of the guide plate 11 changes. In this embodiment, two retracting and releasing components for two wire ropes 12 are used, and the two retracting and releasing components are located at both ends of the free end of the guide plate 11, so that the wire rope 12 is more stable when pulling the guide plate 11. The guide plate 11 plays the role of auxiliary support. In order to prevent the winding rod 13 from rotating, a socket can be opened on the winding rod 13, and the winding rod can be fixed and locked by inserting a pin into the socket. This is a conventional method and will not be described in detail here.

In this embodiment, the mounting groove where the second guide rod 17 is located is connected with the top of the mounting plate 2, and one end of the second guide rod 17 is connected with a detachable horizontal plate 19, so as to facilitate the removal of the disassembled slider 6 in the mounting groove and the removal of the formed reel. When it is necessary to adjust the distance between the upper roller 5 and the lower roller 3, start the third motor 16, which drives the lifting screw 15 to rotate, so that the lifting screw 15 drives the slider 6 to rise and fall in the vertical direction, and the second guide rod 17 guides the slider 6 in another mounting groove, thereby driving the upper roller 5 to rise and fall in the vertical direction, thereby changing the distance between the upper roller 5 and the lower roller 3, so as to adapt to plates of different thicknesses.
[0025] like Figure 3 As shown, further, one end of the upper roller 5 is connected to one of the sliders 6 via a universal joint 18. When the roll of the bent sheet material is taken out, one end of the upper roller 5 can be lifted, thereby facilitating the worker to take out the roll.
[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
