DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figure 1 , the present utility model provides a technical solution: a small flexible rolling mill that can roll metal sheets of different shapes, which is composed of a working machine base 1, a roll gap adjustment system 2, a transmission system 3, and a main motor 4; please refer to Figure 2 , the working machine base 1 includes a base 1.1, a bearing seat 1 1.2, a bearing seat 2 1.3, a guide pillar 1.4, an end cover 1.5, a bracket 1.6, a roll 1.7, a linear bearing 1.8, and a bearing seat 3 1.9. The base 1.1 is connected to the bracket 1.6, the bearing seat 1 1.2, and the guide pillar 1.4 through bolts respectively. The guide pillar 1.4 is connected to the bracket 1.6 to ensure that the roll can run smoothly during operation and play a fixing role; the roll 1.7 is fitted with the bearing seat through bearings, and the end cover 1.5 is fixed to the bearing seat through bolts to ensure the axial fixation of the roll 1.7; the linear bearing 1.8 is connected to the bearing seat 3 1.9 and can vibrate up and down smoothly with the guide pillar 1.4 as the track; please refer to Figure 3 , the roll gap adjustment system 2 includes a pressure sensor 2.1 and an electric cylinder 2.2. The electric cylinder 2.2 is fixedly connected to the bracket 1.6. The electric cylinder screw rod is clamped by the pressure sensor 2.1 and the bearing seat 3 1.9. The up and down vibration of the electric cylinder screw rod drives the up and down vibration of the bearing seat 3 1.9, thereby driving the expansion and contraction of the roll gap.

[0021] Please refer to Figure 4 , the transmission system 3 includes a universal coupling 3.1, a herringbone gear 3.2, a gear shaft 3.3, and a gear shaft baffle 3.4. The universal coupling 3.1 is connected between the roll 1.7 and the gear shaft 3.3 through bolts. When the heights of the roll 1.7 and the gear shaft 3.3 are inconsistent, it can still transmit force and torque smoothly, save space, and play a role in absorption and buffering; the herringbone gear 3.2 is fixed to the gear shaft 3.3 through a positioning pin, and the gear shaft baffle 3.4 is fixedly connected to the base 1.1. The gear shaft 3.3 is fitted with the gear shaft baffle 3.4 through bearings, which can realize the connection and transmission between the main shaft of the rolling mill and the frame and ensure the normal rotation of the rolling mill during high-speed operation; please refer to Figure 5 , the main motor 4 includes a coupling 4.1 and a reducer 4.2. The reducer 4.2 is connected to the gear shaft 3.3 through the coupling 4.1.

[0022] Working principle: As shown in Figure 1As shown, when the small flexible rolling mill is operating normally, power is provided by the speed reducer 4.2. Through the meshing of the lower and upper herringbone gears 3.2, force and torque are transmitted to the universal coupling 3.1. Due to the special structure and design of the universal coupling 3.1, it allows the gear shaft 3.3 and the rolling mill 1.7 to achieve continuous rotation when they are on different axes or have an included angle, and smoothly transmits the force and torque to the rolling mill 1.7, enabling the rolling mill 1.7 to rotate smoothly.

[0023] As Figure 3 As shown, under the action of the electric cylinder 2.2, the lead screw drives the bearing block III 1.9 to vibrate up and down through the pressure sensor 2.1. Since the bearing block III 1.9 is connected to the bearing block II 1.3, it drives the upper rolling mill 1.7 to move up and down. Since the lower rolling mill 1.7 cooperates with the bearing block I 1.2 and the bearing block II 1.3, and the bearing block II 1.3 is fixedly connected to the base 1.1 by bolts and does not move, the lower rolling mill 1.7 only rotates without moving, thereby enabling the adjustment of the size of the rolling gap; under the combined action of the speed reducer and the pressure sensor, metal fabrics with various shapes are rolled, which have the characteristics of small size, high precision, low energy consumption, and high efficiency.

[0024] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
