Technical field
The utility model relates to a kind of drying unit.Particularly a kind of serigraphy drying unit.
Background technology
As shown in Figure 1, serigraphy drying unit of the prior art mainly comprises an electric supply installation 10, one frame 20, one is installed on the workbench 30 at frame 20 tops, one drying unit 40, one is arranged at the control device 50 on the drying unit 40, control device 50 controls drive drying unit 40 along workbench 30 back and forth movements, two ends, the left and right sides, frame 20 top are respectively equipped with first guide rail 21, drying unit 40 is provided with some pulleys 41 along first guide rail, 21 back and forth movements, two ends, frame 20 top are arranged with the auxiliary locator 22 of some equidistant arrangements respectively near the outside of first guide rail 21, when sliding along the first rail under the driving of drying unit at control device, pulley might with the auxiliary locator friction in the track outside, increase the resistance of pulley motion, if things go on like this also might cause mechanical breakdown, influence the operating efficiency of drying unit.
The utility model content
Main purpose of the present utility model be to overcome the prior art pulley easily with the shortcoming of the auxiliary locator friction in the track outside, provide a kind of and pulley and first guide rail are moved to the close ground location in frame both sides make a kind of drying unit that the motion of pulley is not influenced by auxiliary locator.
The utility model adopts following technical scheme: a kind of drying unit, comprise a frame, a control device, a drive unit that links to each other with control device, one is arranged at the horizontal table on the frame and is positioned at workbench top and can be along the drying unit of workbench length direction back and forth movement, described frame is provided with first, second guide rail that is parallel to each other and extends along the workbench length direction, described drying unit is actively supported on described first, second guide rail by transmission mechanism, and can be driven along described first, second guide rail back and forth movement by drive unit.
Further, described transmission mechanism, comprise with first guide rail roll the roller cooperate, be sheathed on the sliding part on second guide rail, and be connected in the support member between roller, sliding part and the drying unit.
Further, be provided with ball between the described sliding part and second guide rail.
Further, the described roller of described drive unit connection driving rolls along first guide rail.
Further, also comprise some sensing devices, this sensing device links to each other with control device and includes and is arranged at the sensing unit on the drying unit and is equipped on sensing unit on the workbench, this sensing unit and sensing unit send signal when touching, described control device receives this signal and controls drying unit toward the rightabout motion.
Further, described drive unit is positioned on the described support member and is motor-driven.
Further, two ends, the described frame top left and right sides are provided with some auxiliary locators that equidistant and left-right symmetry is arranged along the workbench length direction.
By above-mentioned to description of the present utility model as can be known, compared with prior art, the utlity model has following beneficial effect: the utility model is provided with first, second guide rail respectively in the frame both sides, drying unit is actively supported on described first, second guide rail by transmission mechanism, and drives along first, second guide rail back and forth movement by drive unit.The generation of the phenomenon of friction auxiliary locator when adopting this structure can avoid roller to slide has well increased service life of machine, improved operating efficiency and simple in structure, cost is low.
