Abstract
The invention provides a vacuum automatic adjusting device of a cutting bed, belongs to the technical field of cutting beds, and aims to solve the problems of accidents and the like due to infinite increase of negative pressure in the absence of a protection mechanism in the conventional structure. The vacuum automatic adjusting device of the cutting bed is characterized by comprising a vacuum pumping tube of which the head end is connected with the cutting bed, wherein an enclosed tail end is arranged at the vacuum pumping tube; a tail end panel is provided with an axial air inlet hole; a vacuum one-way valve which is controlled to be opened and closed through the negative pressure in the vacuum pumping tube is arranged on the air inlet hole; an air extraction tube which is connected with a vacuum pump is arranged on the side wall of the vacuum pumping tube. The vacuum automatic adjusting device has the advantages of simple structure, low cost, convenience in installation, avoidance of the occurrence of a high-negative-pressure situation, prevention of damage to a cutting bed structure caused by high negative pressure, improvement on the use quality and safety coefficient of the cutting bed, and the like.
Description
Technical field
The invention belongs to cutting technical field, refer in particular to a kind of automatic vacuum regulating device of cutting.
Background technology
Cutting is when cutting out face material, and produce negative pressure with vavuum pump and be adsorbed in cutting by fabric, such fabric can not produce slip staggered floor and displacement.In actual use, cutting vacuum cavity has holding capacity limit to negative pressure, if when the work of vavuum pump makes that in vacuum cavity, negative pressure is excessive, then can damage cutting, and the long-time high negative pressure of vacuum system runs the service life that also can affect self, also easily causes the generation of non-security accident.
Summary of the invention
The object of this invention is to provide a kind of automatic vacuum regulating device of cutting.
The object of the present invention is achieved like this:
The automatic vacuum regulating device of cutting, it is characterized in that: comprise the vacuum-pumping tube that head end connects cutting, vacuum-pumping tube is provided with closed tail end, tail end panel offers axial air admission hole, air admission hole is provided with the vacuum check valve by vacuum cavitations opening and closing in vacuum-pumping tube, the sidewall of vacuum-pumping tube offers the exhaust tube connecting vavuum pump.
In the automatic vacuum regulating device of above-mentioned cutting, the concrete structure of described vacuum check valve is: the sealing plate being provided with salable air admission hole inside tail end panel, sealing plate is fixed with the some thread spindles through tail end panel, the screw thread axle head being positioned at tail end panels outside is provided with self-locking nut, and the thread spindle between self-locking nut and tail end panel overlaps back-moving spring.
In the automatic vacuum regulating device of above-mentioned cutting, the number of described thread spindle is 2-6, is distributed on sealing plate in circumference.
In the automatic vacuum regulating device of above-mentioned cutting, the thread spindle between described self-locking nut and back-moving spring is arranged with spring pad.
In the automatic vacuum regulating device of above-mentioned cutting, the tail end cover of described vacuum-pumping tube has filter cotton, and the inner side of filter cotton is provided with screen pack.
The present invention gives prominence to compared to existing technology and useful technique effect is:
1, the present invention is provided with vacuum check valve, and when the negative pressure in vacuum tube is normal, vacuum check valve is in closed condition, when negative pressure exceedes limit value, then vacuum check valve is opened and is poured into air in vacuum tube, reduces the negative pressure in vacuum tube, the mode simple and fast of adjustment negative pressure.
2, structure of the present invention is simple, with low cost, easy for installation, avoids the appearance of high negative pressure situation, prevents high negative pressure from damaging cutting structure, improves service property (quality) and the safety coefficient of cutting.
Accompanying drawing explanation
Fig. 1 is that structure of the present invention partly cuts open schematic diagram.
Detailed description of the invention
Below in conjunction with accompanying drawing, with specific embodiment, the invention will be further described, see Fig. 1:
The automatic vacuum regulating device of cutting, comprise the vacuum-pumping tube 1 that head end 2 connects cutting, vacuum-pumping tube is provided with closed tail end 3, tail end panel 4 offers axial air admission hole 5, air admission hole is provided with the vacuum check valve by vacuum cavitations opening and closing in vacuum-pumping tube, the sidewall of vacuum-pumping tube offers the exhaust tube 6 connecting vavuum pump.
The concrete structure of described vacuum check valve is: the sealing plate 7 being provided with salable air admission hole inside tail end panel, sealing plate is fixed with the some thread spindles 8 through tail end panel, the screw thread axle head being positioned at tail end panels outside is provided with self-locking nut 9, and the thread spindle between self-locking nut and tail end panel overlaps back-moving spring 10.
Operation principle of the present invention is: vacuum-pumping tube 1 head end 2 connects cutting, when vavuum pump is started working, air is drawn out of through vacuum-pumping tube, produce negative pressure of vacuum absorption fabric, under normal operation: negative pressure of vacuum is less than the elastic force of back-moving spring 10, therefore pull lower seal plate to block air admission hole 5 on tail end panel 4 at back-moving spring 10 elastic force, therefore maintain certain negative pressure value in vacuum-pumping tube and make cutting adsorb fabric;
Overload conditions: when negative pressure of vacuum is greater than the elastic force of back-moving spring 10, then sealing plate is pulled under the effect of negative pressure, and air admission hole 5 is opened, outside air then enters in vacuum-pumping tube, carry out reduction negative pressure, after negative pressure reduces back-moving spring again elastic force under, sealing plate reseals air admission hole 5.
The number of described thread spindle is 2-6, is distributed on sealing plate in circumference.
Thread spindle between described self-locking nut and back-moving spring is arranged with spring pad 11.
The tail end cover of described vacuum-pumping tube has filter cotton 12, and the inner side of filter cotton is provided with screen pack 13.In vacuum-pumping tube, enter dust, keep the clean of cutting inside.
Above-described embodiment is only preferred embodiment of the present invention, not limits the scope of the invention according to this, therefore: all equivalence changes done according to structure of the present invention, shape, principle, all should be covered by within protection scope of the present invention.
