[0020] By adopting the above technical scheme, the bracket base 1 is conveniently installed on the printing equipment as a whole for use through the bracket base 1, and the first motor 3 is used for output, which can drive the bidirectional screw rod 4 in the slide groove 2 to rotate. The surface of the bidirectional screw rod 4 is provided with two groups of opposite thread patterns, and due to the limiting effect of the slide groove 2 on its two groups of threaded sleeves 5, when the bidirectional screw rod 4 rotates, the two groups of threaded sleeves 5 can be driven to move synchronously inward or outward, thereby driving the support frame 6 fixedly connected at the top to move, so as to facilitate the installation or disassembly of the printing roller, and the spacing between them can be adjusted, and the fixing parts provided at one end of the two groups of fixing rods 16 can be used to fix the printing roller. After the printing roller is fixed, the two groups of second motors 7 can be used for synchronous output, and the fixing rod 16 fixedly connected by the second motor 7 can drive the fixing parts provided at one end thereof and the printing roller fixed by the fixing parts to rotate, so that the corresponding printing work can be completed during its rotation.

[0021] Reference Figure 1 , Figure 2 and Figure 3 The fixing member includes two groups of fixing plates 8, and the sides of the two groups of fixing plates 8 away from each other are fixedly connected to one end of the fixing rod 16 passing through the support frame 6 by bolts. The sides of the two groups of fixing plates 8 close to each other are provided with a plurality of groups of limiting grooves 15, and the inner cavity side walls of the plurality of groups of limiting grooves 15 are slidably connected with support rods 12, and the ends of the plurality of groups of support rods 12 away from the fixing plates 8 are fixedly connected to support plates 13 by bolts, and the sides of the plurality of groups of support plates 13 away from the support rods 12 are fixedly connected with elastic anti-skid pads 14, and the sides of the plurality of groups of support rods 12 away from the fixing plates 8 are rotatably connected with push-pull rods 11 by rotating shafts, and the ends of the plurality of groups of push-pull rods 11 away from the support rods 12 are rotatably connected with fixing blocks 10 by rotating shafts, and the side of the fixing blocks 10 close to the fixing plates 8 is fixedly connected with linear actuators 9 by bolts, and the ends of the linear actuators 9 away from the fixing blocks 10 are fixedly connected to one side of the fixing plates 8 by bolts;

[0022] By adopting the above technical scheme, the linear actuators 9 fixedly connected to one side of the two sets of fixed plates 8 are rotated, thereby driving the fixed block 10 to move. Since the multiple sets of support rods 12 are limited by the limiting grooves 15, the multiple sets of push-pull rods 11 connected by rotation on the surface of the fixed block 10 can drive the support rods 12 to slide in the limiting grooves 15, thereby driving the support plates 13 fixedly connected at one end of the multiple sets of support rods 12 to move. When the support plates 13 move outward, the inner wall of the printing roller can be supported and fixed by the multiple sets of support plates 13, and the elastic anti-slip pads 14 provided can improve the stability of the support and fixation of the printing roller, and at the same time, it can also avoid the wear of the inner wall of the printing roller due to excessive supporting force. On the contrary, by extending the linear actuator, the multiple sets of support plates 13 can be driven to move inward to loosen the printing roller, thereby facilitating the removal of the printing roller.

[0023] The implementation principle of a printing roller mounting bracket in the embodiment of the present application is as follows: the bracket base 1 is conveniently installed on the printing equipment as a whole for use, and the first motor 3 is used to output, which can drive the bidirectional screw rod 4 in the slide groove 2 to rotate. The surface of the bidirectional screw rod 4 is provided with two groups of opposite threaded patterns, and due to the limiting effect of the slide groove 2 on its two groups of threaded sleeves 5, when the bidirectional screw rod 4 rotates, the two groups of threaded sleeves 5 can be driven to move inward or outward synchronously, thereby driving the support frame 6 fixedly connected to the top thereof to move, thereby facilitating the installation or removal of the printing roller and adjusting the spacing thereof, and rotating the linear actuators 9 respectively fixedly connected to one side of the two groups of fixed plates 8, thereby driving the The fixed block 10 moves, and since its multiple groups of support rods 12 are limited by the limiting grooves 15, the multiple groups of push-pull rods 11 connected by rotation on the surface of the fixed block 10 can drive the support rods 12 to slide in the limiting grooves 15, thereby driving the support plates 13 fixedly connected at one end of the multiple groups of support rods 12 to move. When the support plates 13 move outward, the inner wall of the printing roller can be supported and fixed by the multiple groups of support plates 13, and the elastic anti-skid pads 14 provided can improve the stability of the support and fixation of the printing roller, and at the same time, it can also avoid the wear of the inner wall of the printing roller due to excessive supporting force. On the contrary, the multiple groups of support plates 1 can be driven to extend by the linear actuator. 3 is moved inward to loosen the printing roller, so as to facilitate the removal of the printing roller. After the printing roller is fixed, it can be output synchronously through the two sets of second motors 7, and the fixing rod 16 fixedly connected to the second motor 7 can drive the fixing piece provided at one end thereof and the printing roller fixed by the fixing piece to rotate, so that the corresponding printing work can be completed during the rotation process. The above-mentioned first motor 3 and second motor 7 can both use NEMA17 stepper motors, which are synchronous motors. The stepper motor controller is an electronic product that can emit uniform pulse signals. After the signal it emits enters the stepper motor driver, it will be converted by the driver into a strong current signal required by the stepper motor, with The stepper motor is driven to operate. The stepper motor controller can accurately control the stepper motor to rotate through each angle. The rotation angle of the stepper motor is usually controlled by controlling the number of input pulses. Each time a pulse signal is received, the stepper motor will rotate a fixed angle. This angle is called the step angle. The rotation direction of the stepper motor is determined by the sequence of the input pulse signals and the direction of the current. The forward and reverse rotation of the motor can be achieved by controlling the pulse sequence and the direction of the current, so as to facilitate the rotation of the printing roller and adjust the spacing between the two sets of support frames 6, so as to facilitate the disassembly and installation of the printing roller. The above-mentioned linear actuator 9 can select a linear actuator 9 with a self-locking function, the model of which is Warner Linear K2G20-12v-BR-04. The linear actuator 9 contains an electric motor.The motor is connected to the screw through a gearbox, thereby driving the screw to rotate. When the screw rotates, the push rod connected to the screw will move linearly to achieve the extension and retraction of the actuator. The entire process does not involve the rotation of any parts. When the motor stops working, the friction between the screw and the nut and the design of the gearbox ensure that the push rod will not move due to external forces, realizing the self-locking function. The overall operation is simple and easy to use, and the printing roller can be quickly fixed and disassembled through its adjustment parts and fixing parts.
