Abstract
The utility model provides a worktable safety elevating structure of a screen process press, which mainly solves the problem of disconnecting the elevating structure of the screen process press. The technical proposal is that the printing worktable elevating structure consists of a drive nut, a moving screw, a guide pole and a one-way connecting sleeve, wherein, the drive nut is mounted on the frame via a bearing and is capable of rotating in situ on the frame; the guide pole is sheathed around the lifter slide; the bottom end of the guide pole is connected fixedly with the one-way connecting sleeve, while the other end of the one-way connecting sleeve is sheathed on the moving screw; the fixing pivot bracket on the moving screw is clamped with the opening of the one-way connecting sleeve; the moving screw is screwed up with the drive nut through threads; the drive nut is connected with the drive motor of the screen process press. The utility model has the advantages of simple structure and convenient use; particularly, in case of abnormalities possible to result in incipient faults below the worktable as the printing worktable descends, the transfer mechanism of the worktable safety elevating structure of the screen process press is automatically disconnected to protect the worktable from any danger.
Description
Affiliated technical field
The utility model relates to a kind of serigraphy machine worktable safety lifting structure, when particularly a kind of workbench promotes by mobile leading screw jack-up, during the workbench landing under the effect of workbench gravity, by the spacing safe lifting structure of mobile leading screw.
Prior art
Popularization and application along with silk screen; screen process press uses in a large number for printing industry; screen process press in use; the user often needs the quality of the serigraphy below the observation printing table; there is potential safety hazard in moving up and down of printing table to the user; now the workbench oscilaltion moving structure of the screen process press of Shi Yonging is directly to be realized by toggle by leading screw drive gong mother or motor; the arrangement of clutch that does not have safeguard protection in the structure that moves up and down owing to the prior art printing machine; the accident of when workbench decline took place operator's head or hand being hindered takes place, so the workbench oscilaltion moving structure of the screen process press of existing use has very big potential safety hazard to the user.
Goal of the invention
For the workbench oscilaltion moving structure of the screen process press that overcomes existing use is to drive the gong mother or motor directly passes through toggle by leading screw; the arrangement of clutch that does not have safeguard protection in the structure that moves up and down owing to the prior art printing machine; the workbench oscilaltion moving structure of the screen process press that uses has the technical deficiency of very big potential safety hazard to the user; the utility model designs a kind of serigraphy machine worktable safety lifting structure; this printing machine move up and down the arrangement of clutch that safeguard protection is set in the structure; workbench oscilaltion moving structure can be thrown off automatically when having an accident, and reaches the safeguard protection effect.
The utility model realizes that the technical scheme that goal of the invention adopts is, serigraphy machine worktable safety lifting structure, comprise: printing table, the printing table riser guide, printing table lifter slide and frame, printing table is fixedlyed connected with the printing table lifter slide, printing table riser guide and printing table lifter slide formation are slidingly connected, the printing table riser guide is fixed on the frame, be provided with the printing table elevating mechanism between described printing table lifter slide and the frame, the printing table elevating mechanism comprises: power gong mother, mobile leading screw, lead, unidirectional adapter sleeve is formed, power gong mother is installed on the frame through bearing, but constitute the flexible connection that power gong mother rotates in the frame original place, lead is sleeved on the lifter slide, fixedly connected with unidirectional adapter sleeve in the lead bottom, the unidirectional adapter sleeve other end is sleeved on the mobile leading screw, fixedly lateral pin on the mobile leading screw and the gap clamping on the unidirectional adapter sleeve, mobile leading screw is connected with the female gong line of power gong, and the power gong is female to be connected with the screen process press power motor.On the described lead, be provided with axial pass trough, positive stop key or elasticity that the rotation of restricted guidance post is set on lifter slide are bumped pearl.
The beneficial effects of the utility model are, and are simple in structure, easy to use; particularly when printing table descends; when the abnormal conditions of potential safety hazard occurring below workbench, safeguard protection is implemented in the travel mechanism's automatic disconnection in the screen process press worktable lifting structure.
Below in conjunction with accompanying drawing the utility model is elaborated.
Accompanying drawing 1 is the utility model schematic diagram on screen process press.
Accompanying drawing 2 is the utility model structural representation.
In the accompanying drawing, 1 riser guide, 2 frames, 3 power gong mothers, 4 move leading screw, 5 leads, 6 unidirectional adapter sleeves, 7 lifter slides, 8 fixing lateral pins, 9 gap, 10 axial pass troughs, 11 workbench.
The specific embodiment
Referring to accompanying drawing, be provided with the printing table elevating mechanism between described printing table riser guide 1 and the frame 2, the printing table elevating mechanism comprises: power gong mother 3, mobile leading screw 4, lead 5, unidirectional adapter sleeve 6 is formed, power gong mother 3 is installed on the frame 2 through bearing, but constitute the flexible connection that power gong mother 3 rotates in frame 2 original places, lead 5 is sleeved on lifter slide 7, fixedly connected with unidirectional adapter sleeve 6 in lead 5 bottoms, unidirectional adapter sleeve 6 other ends are sleeved on the mobile leading screw 4, gap 9 clampings on fixedly lateral pin 8 on the mobile leading screw 4 and the unidirectional adapter sleeve 6, mobile leading screw 4 is connected with the female 3 gong lines of power gong, and power gong mother 3 is connected with the screen process press power motor.
During the work of printing table elevating mechanism, when power gong mother 3 drives the original place forward rotation by the screen process press power motor, mobile leading screw 4 is in power gong female 3 under the effect of gong line, upwards straight line moves, mobile leading screw 4 pushes unidirectional adapter sleeve 6 and lead 5 makes worktable lifting slide plate 7 drive workbench 11 move up along riser guide 1, when power gong mother 3 drives the original place backward rotation by the screen process press power motor, mobile leading screw 4 is in power gong female 3 under the effect of gong line, straight line moves downwards, workbench 11 is under the deadweight effect, remain being connected of unidirectional adapter sleeve 6 and mobile leading screw 4, when the abnormal conditions of potential safety hazard appear for 11 times in workbench, head as the operator, when hand or other foreign matter, foreign matter blocks workbench 11, deviate from the gap 9 of fixedly lateral pin 8 on the mobile leading screw 4 on unidirectional adapter sleeve 6, at this time foreign matter is only born the weight of workbench 10 or under the effect of riser guide 1, foreign matter is only born the part weight of workbench 10, adopt this structure, the foreign matter that the utility model can not occur workbench 11 times, especially when foreign matter for the operator or cause danger during hand.
The utility model keeps unidirectional adapter sleeve 6 and lead 5 not to rotate, be mobile leading screw 4 and reconnecting smoothly after unidirectional adapter sleeve 6 separates, on the lead 5, be provided with axial pass trough 10, positive stop key or elasticity that 5 rotations of restricted guidance post are set on lifter slide 7 are bumped pearl.Positive stop key directly is stuck in groove 10.It promptly is that steel ball is under the elastic force effect of spring by spring controlled steel ball that elasticity is bumped pearl, and steel ball card is at groove 10.
