Forming 1 Ply Bucket Flow Chart According to the molding process, each process of tire forming can be regarded as a relatively independent action combination. In the automatic molding state, after the current process is completed, each action mechanism advances to the preparation position of the next process. When the operation conditions of this process are satisfied, pressing/stepping the 0 switch can perform the corresponding process action ( That is, one of M41, M42, M43, M44, and M45 is turned on). In the manual state, pressing/segment 0 switch (ie, one of M400, M401, M402, M403, M404 is turned on), you can choose to enter any of the internal device states (S). After manually selecting the step segment, the automatic state M61 is turned on, and the program runs the automatic molding operation of the current process segment. This makes it easy and intuitive to read, write, modify, monitor, etc. the automatic part of the control program. The application subroutine and the subroutine nesting (pointer P) realize the automatic state flow, and the repeated action and the action combination are used interchangeably. The molding machine program sets up 13 subroutines and nests them with each other. 13 sub-procedures are: P1 each mechanism resets (return to the original status bit), P2 left mechanism advances, P3 capsule reverses action, P4 buckles advance and retreat action, P5 post-roller reverses action, P6 pushes roller action, P7 refers Forming the positive package, pressing the pressure in place, P8 after the pressure roller is in the package action, P9 expansion, puller linkage on the curtain cylinder, P10 rear pressure roller into, minute, forward rotation action combination, P11 rear pressure roller retreat, combination, reverse Turn action combination, P12 pressure buffer layer preparation position, P13 pressure tread preparation position. Briefly explain the process of forming 3 cloth cylinders: Forming 3 cloth process (sub-program nesting) Ladder diagram indicates application subroutine and sub-program nesting, which can save a lot of program storage space, shorten program scanning cycle and improve output processing speed. In the actual programming and debugging, you should pay attention to the conditions of the subroutine to complete the call and return of the subroutine. It is not possible to force the jump of the ladder ladder, otherwise it will affect the processing of the PLC by the PLC. Apply interrupt processing to improve the accuracy of the puller device. The scan cycle of the interrupt processing example PLC program is 513ms. If the moving speed of the puller is 016m per second, the response delay time of the relay output type is 10ms. Therefore, the action response hysteresis of the puller is 016@(513+10)= 9118mm, which is very different from the process requirement of 2mm. Through the refresh processing of the interrupt and output response, the PLC response lag time is 0102ms, and the puller action response lag is 016@0102=01012mm, thus greatly improving the control precision of the puller in place and ensuring precise control of the process parameters. As shown. In the sequence control block, the following program segments are set: man-machine interface service program, external fault timely monitoring and alarm output, communication and operation on the touch screen, batch output signal mode, basic action unit, manual action unit, automatic Action unit. Conclusion The application of modern digital control technology on the tire building machine greatly improves the running precision of the molding equipment, reduces the loss of parts and the frequency of failures, and facilitates maintenance. It shortens the production cycle of the embryo and improves the production process without affecting the process flow. Labor productivity provides an important guarantee for the improvement of tire product quality, and the effect is remarkable. Through years of design and practice, modern digital control technology has been widely used in our company's bias tire forming machine, rapid capsule reverse forming machine, and radial tire forming machine, so that the functions of the molding machine have been better played. got a good result.

Pneumatic quick connector is a kind of quick connector which is mainly used for air piping and pneumatic tools. It can connect or disconnect the pipeline without tools. When the connector is not connected - when the parent's ferrule moves to the other end, the stainless steel ball will automatically roll outward, and the daughter will be disconnected under the action of the common valve spring force of the parent and the daughter, and the daughter and the parent's valves will be closed respectively, The fluid flow is blocked instantaneously.
