Detailed Description

The utility model provides a protection architecture for lifting unit 2 of silk screen printing machine, for making the utility model discloses a purpose, technical scheme and effect are clearer, more clear and definite, and it is right that the following refers to the drawing and the embodiment is lifted the utility model discloses further detailed description. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the scope of the invention.

Referring to fig. 1 and 2, a protection structure for a lifting assembly of a screen printer comprises a base 1, a beam 4.11 slidably connected to the base 1, and a lifting assembly 2 having two ends respectively connected to the base 1 and the beam 4.11, wherein a protection plate 5 is fixed on the beam 4.11, a protrusion 5.1 is arranged on a side wall of the middle of the protection plate 5, the upper end of the protection plate 5 is arranged on the beam 4.11, and a side wall of the lower end of the protection plate 5 is slidably connected to the base 1.

Be equipped with the slide bar 1.1 of two vertical settings on frame 1, crossbeam 4.11 sliding connection is at the middle part of slide bar 1.1, and the top of two slide bars 1.1 is fixed with connecting plate 1.2, and connecting plate 1.2 is used for keeping the distance of two slide bars 1.1, strengthens slide bar 1.1's intensity for crossbeam 4.11 is more smooth and easy when going up and down.

Specifically, the silk screen and the screen brush and the scraper used for printing are connected to the beam 4.11, and the lifting assembly 2 drives the beam 4.11 to lift, so that the silk screen assembly composed of the structures such as the silk screen, the screen brush, the scraper and the beam 4.11 can lift. When the silk screen printing machine is used, a workpiece to be printed is placed on a workbench on the machine base 1, the lifting assembly 2 drives the silk screen printing assembly to descend, the silk screen printing net is attached to the top surface of the workpiece, and then the net brush is driven to move, so that materials for silk screen printing fall on the corresponding position of the workpiece through the silk screen printing net, and then redundant materials are scraped back to the initial position by utilizing the scraper blade for next silk screen printing.

Wherein, the 2 drives of lifting unit include driving motor 2.1, crank 2.2 and connecting rod 2.3, and crank 2.2 is fixed on driving motor 2.1's output shaft, and connecting rod 2.3 one end is rotated with crank 2.2 and is connected, and the other end is articulated with the crossbeam of silk screen printing subassembly for when driving motor drive crank rotated, drive the connecting rod motion, make the connecting rod drive the lift of silk screen printing subassembly.

A protection plate 5 is fixed on the cross beam 4.11, a bulge 5.1 is arranged on the side wall of the middle part of the protection plate 5, the upper end of the protection plate 5 is arranged on the cross beam 4.11, and the side wall of the lower end of the protection plate 5 is in sliding connection with the machine base 1. Wherein the protection plate 5 is used for limiting the lowest position of the cross beam 4.11 descending. When crossbeam 4.11 dropped to the extreme low position, arch 5.1 butt on the protection shield 5 was on frame 1, even the connecting rod fracture of lifting unit 2 lost the support ability to the silk screen printing subassembly this moment, and the silk screen printing subassembly also can not continue to descend, avoided lifting unit 2's connecting rod fracture to lead to the silk screen printing subassembly to pound heavily on frame 1, and then lead to the silk screen printing subassembly to damage seriously. In practical application, the position limited by the protection plate 5 is substantially the same as or slightly lower than the lowest position driven by the lifting assembly 2, and is used for protecting the silk screen assembly and preventing the silk screen from being damaged due to the change of the position of the supporting block in use or in the machine debugging.

In a preferred embodiment, the protective plate5 has a longitudinal section of

Or "over" the glyph.

Usually, the protecting plate 5 is designed with a "u" shape in cross section, since the base 1 is provided with openings only at the locations where the lifting members 2 are installed, so that the connecting rods can be connected with the cross beams 4.11, and the lifting members 2 pass through the inside of the protecting plate 5. So that the object of the machine base 1 can not enter the position for installing the lifting component 2 from the opening, and the object is prevented from falling on the lifting component 2 to influence the production.

In a preferred embodiment, an elastic pad 5.2 is arranged below the corresponding protrusion 5.1 on the base 1, and the elastic pad 5.2 plays a role in supporting and buffering the protection plate 5 when the protection plate 5 is lowered to the lowest position, namely, in supporting and buffering the silk-screen printing assembly when the silk-screen printing assembly is lowered to the lowest position. The elastic pad 5.2 also prevents objects on the table of the machine base 1 from entering the position of the lifting assembly 2. Among them, the elastic pad 5.2 is preferably a rubber pad.

In a preferred embodiment, the top surface of the elastic pad 5.2 may be slightly higher than the lowest position of the screen printing assembly during normal operation, so that when the screen printing assembly descends, the protrusion 5.1 of the protection plate 5 firstly abuts on the elastic pad 5.2, and then the screen printing assembly is moved to the lowest position during normal operation by using the traction force of the lifting assembly 2, thereby performing screen printing operation. When the connecting rod breaks suddenly or the connecting rod separates from the crank junction, the silk screen printing subassembly slips under the action of gravity, because the support and the shock attenuation of cushion 5.2 for the silk screen printing net can not pound on the workstation on frame 1, avoids the silk screen printing subassembly to damage.

The utility model discloses in, through being equipped with protruding 5.1's protection shield 5 at the fixed middle part in silk screen printing subassembly below, 5 lower extremes of protection shield and frame 1 sliding connection to set up cushion 5.2 on the base that corresponds protruding 5.1 below, make when connecting rod snap or connecting rod and crank junction part separately, the silk screen printing subassembly landing under the action of gravity, because cushion 5.2's support and shock attenuation, make the silk screen printing net can not pound on the workstation on frame 1, avoid the silk screen printing subassembly to damage.
