Detailed Implementation
[0024] 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.
[0025] Reference Figures 1-5This utility model provides an embodiment of a performance matrix curtain retraction machine, including a frame 14. The frame 14 is used to install a horizontal movement component 17 and a control component 16. The control component 16 is disposed inside the frame 14. The horizontal movement component 17 is disposed at the top of the frame 14. The horizontal movement component 17 includes a rack 171 disposed on the outer side of the frame 14. Four evenly distributed mounting plates 172 are fixedly connected to the top of the frame 14. The mounting plates 172 are disposed on both sides of the top of the frame 14. Multiple connecting shafts are fixedly connected to the inner side of each mounting plate 172. 173. Multiple guide wheels 174 are rotatably connected to the outer side of the connecting shaft 173. Auxiliary wheels 175 are rotatably connected to both sides of the mounting plate 172. Limit switches 176 are fixedly connected to the end of the mounting plate 172 away from the frame 14, and limit baffles 177 are fixedly connected to the end of the mounting plate 172 away from the frame 14. When the horizontal moving component 17 moves to a preset safe distance, the limit baffles 177 will trigger the limit switches 176. After the limit switches 176 are triggered, they will immediately send an electrical signal to the control board 164. Upon receiving the signal, the control board 164 quickly cuts off the power supply to the stepper motor 178, causing the stepper motor 178 to stop rotating, thereby stopping the movement of the horizontal moving assembly 17, preventing the equipment from exceeding its working range, and avoiding safety accidents such as collisions. A stepper motor 178 is fixedly connected to the top of the frame 14 and located between the two mounting plates 172. A gearbox 179 is installed on the outside of the output shaft of the stepper motor 178. A mounting box 1711 is fixedly connected to the center of the top of the frame 14, and a drive gear is rotatably connected between the inner walls of the mounting box 1711. The frame 14 has a safety buckle 15 fixedly connected to the top of the wheel 1712. The rack 171 meshes with the drive gear 1712. The safety buckle 15 is located on the outside of the mounting plate 172. The guide wheels 174 abut against the outside of the rack 171. The auxiliary wheels 175 abut against the outside of the rack 171. The limit switch 176 and the limit baffle 177 are arranged opposite to each other. The stepper motor 178 is electrically connected to the control board 164. The output shaft of the stepper motor 178 is fixedly connected to one end of the drive gear 1712 through the gearbox 179.
[0026] Reference Figures 1-5The control assembly 16 includes a curtain retracting roller 161 rotatably connected to the inner wall of the frame 14. A curtain 162 is fixedly connected to the outer side of the curtain retracting roller 161. A counterweight 163 is fixedly connected to the end of the curtain 162 away from the curtain retracting roller 161. A control board 164 is provided on the outer side of the frame 14. The control board 164 is equipped with an LCD screen and electrical auxiliary equipment, which can receive DMX512 signals, realize remote operation of multiple devices through programming, and control the lifting distance and speed of the curtain 162 according to the data values of different signal channels. The control board 164 is provided with power and signal input and output interfaces. The control board 164 is located inside the frame 14 and is situated on the curtain retracting roller 161. A servo motor 165 is fixedly connected to one side of the curtain 161. By controlling the forward and reverse rotation and speed of the servo motor 165, the lifting distance and speed of the curtain 162 can be precisely controlled. The output shaft of the servo motor 165 is fixedly connected to one end of the curtain retractor 161. The servo motor 165 is electrically connected to the control board 164. An LCD screen and electrical auxiliary equipment are provided on the outside of the control board 164. Power and signal input and output interfaces are provided on the outside of the control board 164. The control board 164 can receive DMX512 signals. DMX512 signal is a digital communication protocol widely used in stage lighting and special effects equipment, which can receive signals through different... The control board 164 has a built-in dedicated parsing program that analyzes the received DMX512 signal frame by frame, extracting the data values carried by each channel and converting them into specific executable control commands. This provides a basis for precise control of various parts of the equipment. The control board 164 has power and signal output interfaces on its external side, enabling network programming of multiple performance matrix curtain retractors. When multiple devices work collaboratively, the control board 164 synchronously adjusts the stepper motors 178 and servo motors of each device based on the data values of different channels in the received DMX512 signal. The servo motor 165 operates in a specific manner. The frame 14 is made of galvanized steel plate and a skeleton structure. By adjusting the speed and direction of the stepper motor 178 on different devices, the speed and direction of horizontal movement of each device can be controlled, so that they form a specific arrangement or movement trajectory in the horizontal direction. By adjusting the speed and direction of the servo motor 165 on different devices, the lifting speed and height of the screen 162 on each device can be controlled, so that they form different projection effects in the vertical direction. Ultimately, the coordinated dynamic projection effect of multiple matrix screen projectors in the horizontal and vertical directions is realized, which meets the needs of complex stage performances and special effects displays.
[0027] Working principle: First, it receives externally transmitted DMX512 signals through the signal input interface on its outer side, controlling the stepper motor 178. The output shaft of the stepper motor 178 transmits rotational power to the gearbox 179. The gearbox 179 processes the power through speed change and torque amplification, making the output power more suitable for driving subsequent transmission components. The power processed by the gearbox 179 is transmitted to the drive gear 1712, driving the drive gear 1712 to rotate around its axis. The drive gear 1712 meshes with the rack 171 fixedly installed at the top of the frame 14. When the drive gear 1712 rotates, its teeth mesh with the teeth of the rack 171 in sequence, converting the rotational motion of the drive gear 1712 into the linear motion of the rack 171. Since the horizontal moving component 17 is connected to the rack 171, the linear motion of the rack 171 drives the entire horizontal moving component 17 to move horizontally linearly along the top of the frame 14. During the process, both the guide wheel 174 and the auxiliary wheel 175 abut against the outer side of the rack 171. As the rack 171 moves, the guide wheel 174 and the auxiliary wheel 175 rotate synchronously, providing lateral support and guidance for the rack 171, preventing the rack 171 from deviating or wobbling during movement, thereby ensuring the smoothness and accuracy of the horizontal moving component 17's movement. At the same time, each mounting plate 172 is fixedly connected to a limit switch 176 and a limit baffle 177 on its top. When the horizontal moving component 17 moves to a preset safe distance, the limit baffle 177 will trigger the limit switch 176. After the limit switch 176 is triggered, it will immediately send an electrical signal to the control board 164. After receiving the signal, the control board 164 will quickly cut off the power supply to the stepper motor 178, causing the stepper motor 178 to stop rotating, thereby stopping the movement of the horizontal moving component 17, preventing the equipment from exceeding the working range, and avoiding safety accidents such as collisions.
[0028] In the control component 16, the servo motor 165 starts rotating according to the instructions issued by the control board 164. The servo motor 165 has high-precision speed and position control capabilities, and can accurately adjust the rotation speed and angle of its output shaft according to the control signal. The output shaft of the servo motor 165 is fixedly connected to one end of the curtain retractor 161, so the rotational power of the servo motor 165 is directly transmitted to the curtain retractor 161, driving the curtain retractor 161 to rotate around its axis. When the curtain retractor 161 rotates clockwise, the curtain 162 gradually gathers under the winding action of the curtain retractor 161. The counterweight 163 rises as the curtain 162 is retracted. When the curtain retraction roller 161 reverses, the curtain 162 gradually unfolds under the gravity of the counterweight 163, and the counterweight 163 descends as the curtain 162 unfolds. The control board 164 is equipped with power and signal output interfaces on its outer side. Through these interfaces, multiple performance matrix curtain retraction machines can be networked and programmed. When multiple devices work together, the control board 164 synchronously adjusts the operating status of the stepper motor 178 and servo motor 165 of each device according to the data values of different channels in the received DMX512 signal.
[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
