[0002] With the continuous development of science and technology, electronic display screens have been better applied. However, traditional calligraphy and painting flipping equipment still has irreplaceable practical significance. On the one hand, the manufacturing cost and use cost of such equipment are lower than those of electronic display screens. On the other hand, the use environment of calligraphy and painting flip billboards, timeboards or scoreboards is limited, and it is inconvenient to use electronic display equipment.

[0003] In view of the above situation, the prior art application No. 202222827475.0 discloses a mechanical matrix flipping machine, which integrates multiple flipping units into a cabinet to achieve a centralized display effect. However, its disadvantages are also obvious. On the one hand, the combined connection of the flipping units in the device relies on the cabinet to support the device, which results in the combined connection of the flipping units being restricted by the cabinet form, and the combination is not flexible enough. On the other hand, as far as the single flipping mechanism in its flipping unit is concerned, the setting form is also unreasonable. The device uses Hall elements to detect the display patterns of calligraphy and painting cards. In this way, it is necessary to arrange magnets in an array on its rotating drum, and its motor is integrated in the drill barrel. While it is inconvenient to overhaul, the flipping and detection of calligraphy and painting cards operate independently, with low coordination and integration, which is more complicated for assembly, debugging, overhaul and maintenance. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art and provide an electric turning machine for calligraphy and painting cards which has a simple structure, flexible assembly layout, can realize free combination of calligraphy and painting cards, and has a more reasonable transmission and detection structure. It organically combines the light sensing device with the calligraphy and painting turning power using a dual-axis motor to collaboratively realize calligraphy and painting turning and display pattern detection.

[0005] The device comprises a body shell, the front and rear of the body shell are hollowed out, and a calligraphy and painting card limit baffle is arranged on the upper front part of the body shell, and the calligraphy and painting card limit baffle is in the form of a rectangular plate;

[0006] An assembly support is fixedly arranged on the back of the body shell, and a first assembly hole group is arranged on the assembly support; second assembly hole groups are arranged oppositely on both sides of the body shell;

[0007] A stepper motor is arranged in the housing, and the stepper motor is a dual-axis motor;

[0008] A light shielding element is arranged on the output shaft at the rear end of the stepper motor. A photoelectric sensor is arranged in the housing corresponding to the light shielding element. The light shielding sheet passes through the photoelectric sensor so that it outputs a signal to the circuit board chip. The circuit board chip signal is connected to the stepper motor.

[0009] The front output shaft of the stepper motor is provided with a first synchronous wheel;

[0010] The first synchronous wheel is connected to the calligraphy and painting board flipping unit by power, that is, driven by a stepper motor, synchronously drives the shading element to rotate and the calligraphy and painting board to flip, forming a coordinated control.

[0011] The beneficial effects of the utility model are as follows: the device has a simple structure and low cost, and compared with similar products in the prior art, its arrangement is more reasonable. On the one hand, through the free combination of combined connecting parts, multiple single devices can form a freely combined display matrix, and its applicability is higher; on the other hand, the transmission mechanism and the photoelectric trigger mechanism of the device are more reasonably arranged, and the coordinated linkage of the two mechanisms is achieved through the dual-axis motor, and its assembly, debugging, inspection and maintenance are simpler, and it has more market promotion value.
