Description
Technical Field
The invention relates to a plastic suction table board, in particular to an ultra-thick hollow plastic suction table board structure and a plastic suction process thereof.
Background
At present, the hollowed-out table top is mainly applied to furniture such as island cabinets, dressing tables and the like, and is usually matched with materials such as glass, stone, veneer and the like for use. The hollow table-board base material generally comprises solid wood, a medium density fiberboard, an aluminum material and the like, and the surface treatment forms of the hollow table-board base material mainly comprise three types: firstly, coating and then splicing the frame; the second is to assemble the frame or to draw plastic after routing, and the third is to assemble the frame or to spray paint after routing.
For a table top formed by splicing frames or performing plastic suction after routing, the common table top is shaped and structured as shown in fig. 1. Due to the shape and structure of the hollow-out part, the hollow-out part usually has three surfaces, namely an A surface 1, a B surface 2 and a C surface 3. When the thickness of the table top is too thick (thickness ≧ 30 mm), especially when the B surface 2 is thick (thickness ≧ 25 mm), due to the limitation of conditions such as pressure, the blister film often appears and can not be adsorbed to the seam between the upper and lower films during the blister process, resulting in that the blister is not in place, and the blister film can not be attached to the substrate, such as F point. When the breadth size of the table top is smaller and the thickness is larger, the phenomenon of plastic suction failure is easier to occur.
For the ultra-thick hollow plastic-suction table top, the common structure and process can cause the rework rate to be very high, the manpower and material resources are consumed, the production efficiency of a factory is limited, and the production cost is increased.
Disclosure of Invention
The invention aims to provide an ultra-thick hollow plastic-absorbing table top structure and a plastic-absorbing process thereof by considering the problems.
In order to realize the purpose, the invention adopts the technical scheme that: a super-thick hollow plastic suction table top structure comprises a light-seeing surface and a back surface, wherein a stepped hollow structure is arranged between the light-seeing surface and the back surface; the stepped hollow structure is composed of a visible light surface groove structure consisting of a vertical surface A close to the visible light surface and a horizontal surface B, a middle groove structure consisting of a vertical surface C in the middle, and a back surface groove structure consisting of a horizontal surface D and an inclined surface E close to the back; two ends of the D surface are respectively connected with the C surface and the E surface; the length L of the D surface is the distance between the two ends of the D surface and the intersection point of the C surface and the E surface respectively; the two sides of the E surface facing the back surface are inclined in a splayed shape, and the inclination angle between the E surface and the bottom surface is beta.
As an improvement of the above-described aspect, the inclination angle β is in a range of 45 ° ≦ β ≦ 75 °. Because the mesa is thicker, and E face depth is darker, if E face is the perpendicular, can lead to the blister not in place. The E surface is set to be the inclined surface, so that the extension of the plastic film under pressure can be effectively reduced, the probability that the plastic film and the vacuum film laminating machine silica gel film are broken by pulling is reduced, and the tight adhesion of the plastic film and the substrate is ensured. The inclination angle beta of the E surface is the included angle (acute angle) between the E surface and the horizontal plane, and the range is between 45 degrees and 75 degrees.
As the improvement of the technical scheme, the length L of the D surface is 3mm-5mm; the length L of the D surface is recommended to be controlled in the range of 3mm to 5mm. When the L value is too small, trimming and defect covering are inconvenient; when the L value is too large, excessive milling is performed, plates are wasted, the efficiency is reduced, and the plastic suction film at the intersection of the D surface and the E surface can not be sucked in place and is easy to degum.
Meanwhile, the invention also provides a plastic suction process which is simple to operate and easy to realize and aims at the super-thick hollow plastic suction table top structure, and in order to realize the purpose, the technical scheme adopted by the invention is as follows: a plastic uptake process using the super-thick hollow plastic uptake table-board structure comprises the following steps:
(1) Preparing materials;
(2) Carrying out modeling processing on the table board through CNC, and sanding the processed table board;
(3) Spraying glue on the back and sucking plastic; the method comprises the following specific steps: cleaning the back surface of the table board, and spraying glue on the back surface, the surface E and the surface D; standing the greenhouse; back face plastic uptake; trimming and cleaning;
(4) Spraying glue and sucking plastic on the exposed surface; the method specifically comprises the following steps: cleaning the visible light surface of the table top; spraying glue on the light-emitting surface, the C surface, the B surface and the A surface; standing the greenhouse; plastic uptake is carried out on the visible light surface; trimming and cleaning;
(5) And collecting the library.
As an improvement of the above technical solution, the back face blister in the step (3) and the light-viewing face blister in the step (4) are completed on a cushion block.
As an improvement of the technical scheme, the length L of the cushion block Length of cushion block Comprises the following steps: l is Length of cushion block ＝L Length of hollowed-out table top -2 xd; wherein L is Length of hollowed-out table top The length of the table top is hollowed; d is a single-side gap between the table top and the cushion block, and d is less than or equal to 50mm and less than or equal to 300mm. When plastic is sucked on the vacuum film laminating machine, the middle of the table top is in a hollow state, so that the silica gel film and the plastic sucking film of the film laminating machine can be excessively stretched to the platform under vacuum pressure and are adsorbed on the platform; when the atmospheric pressure is restored, the plastic film is not easy to leave the platform, and the silicone film is tightly attached to the plastic film, so that the silicone film and the plastic film are pulled together when the plastic film is taken out of the warehouse, the plastic film is peeled off at the table part, and the plastic suction fails; meanwhile, the silica gel membrane is very easy to damage; after the cushion blocks are added, the plastic-absorbing film and the silica gel are coated due to the relatively small gap between the table top and the cushion blocksThe film can not contact with the platform under vacuum pressure, or the contact area is relatively small, so that the film can be timely separated when the normal pressure is recovered, and the stripping condition of the plastic uptake film is greatly reduced.
The hollow plastic suction table top is additionally provided with a D surface and an E surface on the basis of the original C surface; the D surface is mainly used for hiding the seams of the plastic uptake films and the possible defects at the seams, and is convenient for workers to cut redundant plastic uptake films in the cutting and repairing process after plastic uptake is finished, so that the trimming efficiency is improved, and the quality problem caused by trimming is reduced. Because the mesa is thicker, and E face depth is darker, if E face is the perpendicular, can lead to the blister not in place. The E surface is set to be the inclined surface, so that the extension of the plastic film under pressure can be effectively reduced, the probability that the plastic film and the vacuum film laminating machine silica gel film are broken by pulling is reduced, and the tight adhesion of the plastic film and the substrate is ensured.
