The specific embodiment
The utility model will be incorporated on the support arm that the screen frame frame is installed from net height degree adjusting device, thereby propose a kind of adjustable for heightly from net mechanism and adopt the flat surface screen printing machine of this mechanism from net, realize printing adjustable at any time from the net height degree.
Fig. 1 is the partial structurtes schematic diagram according to the flat surface screen printing machine of the utility model embodiment.As shown in Figure 1, the printing crossbeam 2 of this printing machine is installed on the lifting and guiding device 3 that is fixed on the frame 7, and can slide along lifting and guiding device 3.Printing crossbeam 2 is installed with from net mechanism hold-down arm 50 at printing initiating terminal (being the left side among Fig. 1), and printing crossbeam 2 is installed with screen frame frame hold-down arm 1 at printing clearing end (being the right side among Fig. 1).Screen frame frame 6 is used to install half tone mechanism, and this screen frame frame 6 is positioned at a side 61 of printing initiating terminal by being movably connected on net mechanism hold-down arm 50 from net mechanism 4, and 62 of the sides that this screen frame frame 6 is positioned at the printing clearing end are fixedly mounted on the screen frame frame hold-down arm 1.Thereby printing initiating terminal one side 61 of screen frame frame 6 can be printed clearing end one side 62 (being stiff end) rotation around it, as shown in Figure 2.Begin to move the process of printing from the printing initiating terminal in printing mechanism's (not shown), gradually printing initiating terminal one side 61 of screen frame frame 6 is risen, as shown in phantom in Figure 2, thereby half tone is separated with stock from net mechanism 4 to the printing clearing end.
Below with reference to the detailed structure of introducing according to an embodiment of the utility model of Fig. 3-Fig. 5 from net mechanism.
As shown in Figure 3, should comprise cylinder 47 that is fixedly mounted on net mechanism hold-down arm 50 and the leading screw 41 of fixedlying connected from net mechanism with the piston rod of cylinder 47, the other end of this leading screw 41 is clamped and installed on the connecting plate 51 apart from regulating handle 42 and locking nut 43 by net, and this connecting plate 51 is fixedlyed connected with printing initiating terminal one side of screen frame frame 6 by the axis of guide 52.When printing machine began to print, cylinder 47 air inlets were stretched out the piston rod of cylinder 47, drove leading screw 41 simultaneously and rose, and then up lift by printing initiating terminal one side that the connecting plate 51 and the axis of guide 52 drive screen frame frame 6, and half tone is separated gradually with stock.
Further, in order to make this, should be provided with from net height degree adjusting device from net mechanism from netting the adjustable of mechanism from the net height degree.Specifically as shown in Figure 4 and Figure 5, on cylinder 47, be installed with adjustable plate 49 down, fixedly mounting two support columns 46 on the adjustable plate 49 down again, then fixed installation adjusted plate 45 on two support columns 46.Support column 46 can be fixedlyed connected with following adjustable plate 49 and adjusted plate 45 by existing variety of way (for example being threaded).The center of adjusted plate 45 is provided with tapped through hole 451, and realization and adjusted plate 45 is threaded from net height degree regulating sleeve 44 screws in the tapped through hole 451 of adjusted plates 45 by its threaded shank 442 in.Also be provided with adjusting flange 441 in the upper end of its threaded shank 442 from net height degree regulating sleeve 44,, just can make from net height degree regulating sleeve 44 to change height with respect to adjusted plate 45 by rotating this adjusting flange 441.And, should be provided with through hole 443 from the center of net height degree regulating sleeve 44, the diameter of this through hole 443 can not interfere so that screw mandrel 41 passes from net height degree regulating sleeve 44 greater than the external diameter of screw mandrel 41.
When printing machine begins to print, as previously mentioned, cylinder 47 air inlets, the piston rod 471 of cylinder 47 is stretched out, driving leading screw 41 and spacing shim 48 simultaneously rises gradually, with when the lower surface of net height degree regulating sleeve 44 is close to, piston rod 471 and screw mandrel 41 no longer rise until the upper surface of spacing shim 48, and arrive the highest from the net position this moment from net mechanism.That is to say, cylinder original state lower limit pad 48 and the distance between net height degree regulating sleeve 44 be this from net mechanism from the net height degree.Thereby, change its positions by rotation from net height degree regulating sleeve 44 with respect to adjusted plate 45, just can change the distance between net height degree regulating sleeve 44 and spacing shim 48, also promptly change this from net mechanism from the net height degree.
Shown in Figure 6 is from the original state schematic diagram when the net height degree is adjusted to h1 of netting mechanism, Fig. 7 then is spacing shim 48 and the printing final state schematic diagram when net height degree regulating sleeve 44 offsets, and be raised to extreme higher position from netting printing initiating terminal one side of mechanism with the screen frame frame this moment.For obtain than shown in Fig. 6,7 from net height degree h1 higher from net height degree h2, only need and up to screw out with respect to adjusted plate 45 from net height degree regulating sleeve 44, just the distance between net height degree regulating sleeve 44 and spacing shim 48 can be increased to h2, as shown in Figure 8.Otherwise,, then will down screw in respect to adjusted plate 45 and get final product from net height degree regulating sleeve 44 if need lessly from the net height degree.Therefore, of the present utility model from the net mechanism can realize any adjusting that stock is required from the net height value, and regulate easy to operate, simple in structure, low cost of manufacture.
Below introduced single armed off-grid type flat surface screen printing machine and adjustable for height from net mechanism in conjunction with the embodiments from net.Obviously, the utility model also applicable to both arms from net, realize that both arms are from the adjustable for height flat surface screen printing machine of net, initiating terminal and clearing end that its two arm prints each other.In addition, more than adopt among the embodiment of the present utility model cylinder as from the net drive unit, the piston rod by cylinder lifts screw mandrel and then lifts the screen frame frame as drive rod.Obviously, among other embodiment, the drive unit that the utility model can adopt hydraulic cylinder or other to have fixed journey system replaces cylinder.
