[Prior Art] 稷 When the screen printing machine is running, its printing motor will drive the printing head forward, so that the ink on the screen starts to be applied to the workpiece. In order to improve the printing quality, the screen can be lifted to a tilt angle while the printing operation is being performed, so that the screen can be gradually separated from the ink on the printed matter, and a better screen printing effect can be achieved. In the existing screen printing machine lifting mechanism, it mainly includes two main forms of direct air M cylinder lifting and chain transmission lifting. Among them, the direct air pressure red lifting plate mainly uses the electromagnetic valve to move, so that the pneumatic cylinder advances and retreats, with the printing work = gradually raising the screen, to raise the screen function, but it will shoot many ^ 'including: lifting height Depending on the cylinder stroke, and with the gas (four)! Two:: Loss of speed is not good control 'unstable, too fast, this is special gas = lift version when f network version will be with the key touch, so straight easy ^ ^ [cylinder too large, will make the screen pressure If it is too big, it will be lacking. If it is too small, there will be an unsatisfactory situation. This action asks: The degree of convergence needs to be slowly increased. However, it is very difficult to control it only by pressure. This is another shortcoming. M311584. In addition, the direct force of the direct pneumatic cylinder lifting method is tolerated by the gas, and the size of the pneumatic cylinder must be the size of the condition. For large machines, for example, the use of large gas cylinders not only takes up space 'the whole system The gas loss is also greater than 0. In addition to the higher cost, the chain drive is used. When the drive motor starts to run, the screen is started, because the chain, the sprocket, the reducer and the eccentricity are simultaneously set. At the beginning of printing, the screen has been lifted by two-stage distance, and its print f is not ideal. At the same time, the lifting plate is a mechanical action. If the plate is lifted twice, if the pressure of the screen plate and the squeegee is relatively large, it is very easy to damage the screen. [New Content] The main purpose of Sakamoto's creation is to provide a screen printing elevating structure that can effectively achieve the function of making the screen slowly and steadily. The second purpose of this creation is to provide a kind of screen printing and lifting structure, which can be used in a large-sized structure to make the driving components not have too much power to raise the heavy weight of the frame group. The machine's can reduce the size of the pneumatic cylinder and reduce the loss of the overall system air pressure. Another object of the present invention is to provide a screen printing elevating structure which can be installed with a pressure valve via a pneumatic circuit of the driving element to control the pressure of the screen and the squeegee during the lifting process, thereby prolonging the life of the screen. In order to achieve the above purpose, the present invention mainly installs a lifting device corresponding to the mesh frame on both sides of the screen printing machine, wherein the lifting device is connected with a driven member by a driving member, and is driven. The other end of the piece is connected with a lever, and the other end of the lever is connected with the frame clamp. The above-mentioned follower is provided with a through hole, and a shaft is sleeved with M311584 on the through hole of the two side followers. In this embodiment, the above-described lifting device is driven and has a crank structure. In the preferred embodiment, the driving element is a plenum=version device that is actuated before and after the tamping, so as to drive the county piece ^=cup, and the lever is connected to the frame clamp, the frame The screen is equipped with a screen plate, and the phase rod drives the frame clip to be followed, so that the screen plate can be improved by the printer with a smoother ink on the tilting screen. In the embodiment, the driving component is also a motor component, and the driving member moves the follower to follow the motor. The motor rotates to connect the lever of the other end of the driven member to the frame clamp, and the motor is smoothed. Power output, so that the speed of the screen can be matched with the printing operation, 'making the ink on the screen more smooth when printing, which helps the printed matter to be more precise. In a feasible embodiment, the device is further provided with an adjustable stop block on the mesh frame. The adjustable stop block is a rotatably adjustable height, which helps the screen to be lifted during the lifting process. The block is set to withstand the frame clamp continues to rise 'so that the screen will not exceed the ideal lifting height, and the maximum lifting height can be controlled by rotating the adjustable stop block. w As described above, by using the mechanism of the lifting device, the linkage mechanism is used, so that the driving component does not need to output a large force, and the heavy-weight frame clip can be raised and the 罔 version is suitable for use in various kinds. The screen printing machine of the specification can reduce the cost of the sigh, and can reduce the loss of the overall system air pressure, and adjust the speed of driving the component with the printing stroke, # to control the speed of the lifting, so that the screen has a tilt Angle, the printing head drives the ink on the screen to be more smooth. The M311584 is smoother, making the substrate more precise after printing. [Embodiment] In order to facilitate the review committee to further develop a deeper, clearer and more detailed understanding and understanding of the structure, use and features of this creation, Mai will give a better example, with the following detailed description : First, as shown in the first to third figures, the case is set in the screen printing machine related to the screen printing machine Η), the screen printing mechanism 10 is basically provided with frame force on both sides: U' in the net frame Under the η, there is a frame "12, and the two sides of the net frame ^ clothes are not available for the print head 13 to be traversed left and right. This creation is mainly based on the two sides of the screen printing mechanism (4) u end phase:: where the lifting device 20 is set, wherein the lifting device 2 is connected by a member 21 - the follower 22 ' And connected to the follower 23 3 end - the beak 23', the other end of the lever 23 is connected to the frame clamp 12, and the follower μ is provided with a through hole 24, and is sleeved on both sides with the support shaft 25 In the implementation of the present invention, the frame clamp 12 is provided with a printing net, and the follower 22 is an L-shaped crank structure. In the entire embodiment, the driving element 21 is a pneumatic cylinder, and the operation, and the second garment 20 is actuated before and after the pneumatic cylinder, so that the continuous mechanical frame clamps 22 move the damage rod 23, because Horizontal (four) connected to the farm set 20 Τ - 23 drive the frame clamp 12 followed by the improvement, the overall lift (four) pneumatic cylinder action, to make the screen 14 improved with a tilt and the screen on the moving screen 14 is smoother print. Referring now to Figures 4 and 5, for the creation of the operating state embodiment 7 M311584, the driving element 2 "uses pneumatic red as the driving device, when the screen printing mechanism 10 is printing, the driving element 21 begins Actuating the driven member 22, the follower 22 is linked to drive the lever 23, and the lever 23 raises the frame clamp, and the driven member 22 acts as a point, and the distance moved by the driving member 21 is converted into the lever 23 The moving distance and the screen 14 on the frame clamp 12 are gradually increased, and the speed of the movement of the printing head 13 is fully synchronized to achieve the effect of printing-edge printing, and when the printing is completed, the screen printing mechanism 10 controls The driving element 21 returns to the original state, and the lifting device 2 will lower the calling frame clamp 12 back to the original height to match the next printing stroke. For example, as shown in Figures 5 to 7, the original lifting device 2 In the action diagram of the mechanism, if the movement distance of the frame clamp 12 is γ, it is divided by the distance 1 between the center of the through hole 24 and the lever contact 231 and the distance L between the center of the through hole 24 and the contact of the drive element 2 ιι and multiplied by the drive. The distance 元件 moved by the component 21 causes the screen 14 to move The moving distance can be adjusted by the ratio of the distance from the through hole 24 to the distance between the lever 23 and the through hole 24 to the driving element 21, and the ratio of the sliding member 22 can be designed by using the above proportional relationship, and the adjustment of the lifting speed can be performed even if the driving element 2 is driven. The moving distance is the same in unit time, because the follower 22 has different specifications, and there are different proportions, so that the height and speed of the lifting can be controlled to match the printing stroke', and the lifting operation is slower and more stable. Note that the screen elevation distance is the movement distance of the frame clip Υ 'where Y = (1/L) X' Υ is the moving distance of the frame clamp 12, X is the moving distance of the driving element 21, and L is the through hole 2 4 The center point to the driving element contact 211 is the distance between the two, and L is the distance between the center point of the through hole 24 and the lever contact 231, so that the above-mentioned follower 22 can be adjusted to have a different ratio of 1 and L, and the height of the lifting plate can be M311584. In a possible embodiment, the driving element 21 can also be a motor element. The operation of the trans-motor element causes the follower 22 to follow the motor element, and the motor element rotates to connect the other end of the follower 22. Women 23# high version box Yang 1 2, through the smooth power output of the motor, the screen 14 raising speed can be matched with the printing operation, so that the ink on the screen 14 is more smooth in printing, and the printing is more excellent. In the yoke example, a pressure valve can be added to the pneumatic circuit of the pneumatic cylinder of the lifting plate to control the pressure of the lifting screen 14 and the squeegee so that the mesh is not tightened due to the lifting of the mesh. Extend the life of the screen 丨4. Through the above-mentioned linkage mechanism, the principle of the lever allows the pneumatic cylinder to lift the heavy-weight frame clamp 12 without much force, and does not need to replace the pneumatic cylinder due to the large machine. Set the cost of the machine and save space, and reduce the loss of the body's air pressure to achieve a labor-saving effect. Furthermore, the arrangement of the fulcrums 25 enables the two lifting devices 2 〇 to perform the lifting operation in synchronization with the springs, since the follower 22 is sleeved on the fulcrum 25, and when the follower 22 is driven to the driving member 21 The shaft 25 is rotated, and the support shaft 25 synchronously rotates the two driven members 22, so that the lifting action can be consistent, and the purpose of the synchronous lifting is to avoid the inconsistency of the lifting speeds of the two lifting devices. Moreover, in a possible embodiment, an adjustable stop block 15 is further disposed on the mesh frame, and the adjustable stop block 15 is a rotatably adjustable height, and the height of the screen 14 can be raised. In the middle, the screen 14 is set again due to the σ of the adjustable stop block 15, and the frame clamp 12 continues to rise without exceeding the ideal M311584 lifting height, and the adjustable stop block 15 can be rotated to control the lifting. The height of the plate is used to prevent the frame clamp 12 from being driven too high by the lifting device 20, and the mesh cloth is damaged, and the lifting height can be freely determined. Referring to FIG. 8 , in another preferred embodiment of the present invention, the lifting device 20 is disposed at a position corresponding to the front end of the two side net frames u, and is also disposed at the rear end of the net frame 11 . The device 20 can realize the bilateral lifting by using the lifting device 20, and cooperate with the printing head 13 to print back and forth, so that the overall screen printing mechanism 1 can meet the requirement of the reciprocating two-way movement, so that the screen Η has an inclined angle. The printing head 13 drives the ink on the screen 14 to be smoother, so that the substrate is more precise after printing. Hu Jin < With the structure of this creation, you can quickly follow the screen printing agency. The P-brushing line ′ achieves the effect of the edge-printing edge, and the fast-acting driving element 21 is combined with the stable mechanical structure, so that in the printing operation,
