Description

Anti-sticking continuous press

Technical Field

The invention relates to the field of plate processing equipment, in particular to an anti-sticking continuous press.

Background

The adhesive used by a plurality of common boards (shaving boards or density boards) at present is urea-formaldehyde resin adhesive, the adhesive is a combination of formaldehyde and urea, so that the free number of formaldehyde contained in the boards is high, the formaldehyde is a substance which has great harm to human bodies, and the skin can cause allergic dermatitis, color spots and necrosis by directly contacting the formaldehyde, and bronchial asthma can be induced when high-concentration formaldehyde is inhaled. Formaldehyde has an irritation effect on skin mucosa, is a raw pulp toxic substance, can be combined with protein, and causes severe irritation of respiratory tract, edema, eye irritation and headache when inhaled at high concentration. Chronic respiratory diseases, nasopharyngeal carcinoma, colon cancer, brain tumor, menstrual disorder, gene mutation of cell nucleus, DNA damage repair inhibition, pregnancy syndrome, chromosome abnormality of newborn, leukemia, and memory and intelligence deterioration of teenagers can be caused by long-term exposure to low-dose formaldehyde.

The higher the environmental protection grade, the lower the formaldehyde content in the glue used in the manufacturing process. If aldehyde-free additive boards are to be produced, formaldehyde-free adhesives (such as MDI (isocyanate), PMDI, etc.) are used as adhesives. However, when the aldehyde-free adhesive is used for producing a plate, a plain plate (a shaving board or a density board) can be bonded with a hot pressing plate of a press, the quality of a product can be seriously influenced, the hot pressing plate can be directly damaged, and in serious conditions, the production cannot be normally carried out.

In addition, the current production of aldehyde-free plates by continuous presses is mainly to spray a release agent against the steel strip or the surface of the workpiece to deactivate the aldehyde-free adhesive (such as MDI (isocyanate), PMDI, etc.) on the surface of the workpiece to prevent the adhesion of the steel strip. In addition to increasing production costs, mold release agents can also reduce product quality. The surface layer containing the release agent is generally removed in a subsequent sanding process. However, if the removal is not complete, the release agent contained in the workpiece will form new contamination, and the strength of the place containing the release agent in the workpiece will be obviously reduced, even the workpiece will crack.

Drawings

In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the drawings used in the description of the embodiments will be briefly introduced below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and other drawings can be obtained by those skilled in the art without inventive efforts, wherein:

fig. 1 is a schematic view of the overall structure of a preferred embodiment of an anti-sticking continuous press according to the present invention.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely below, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, an embodiment of the present invention includes:

the main technology of the anti-sticking continuous press is as follows: when an aldehyde-free adhesive (such as MDI (isocyanate), PMDI (polymethylenediisocyanate) and the like) is used as an adhesive in a continuous press to produce a particle board or a density board, an anti-sticking structure (such as Teflon and the like) is used for modifying the surface of a steel belt of the continuous press, so that the plain board (the particle board or the density board) and the steel belt of the press are prevented from being bonded.

An anti-sticking continuous press comprising: the setting is on hot pressboard 1 and have relative motion's transport structure with the hot pressboard, and transport structure is provided with anti-sticking structure including transporting conveyer belt 2 (the steel band can be selected to the conveyer belt) and driving its motion band pulley 3 and drive arrangement of panel 5 on the conveyer belt, anti-sticking structure's material can select special fluorine dragon, when setting up anti-sticking structure on the conveyer belt, mainly has two kinds of modes:

1. an anti-sticking structure is directly arranged on the conveying belt by using a spraying device 4;

2. the method comprises the steps of firstly, carrying out some pretreatment on the surface of the steel strip, for example, manufacturing some special patterns or structures on the surface of the steel strip, wherein the patterns or structures comprise various types such as honeycomb structures, wave structures, irregular structures and the like, and then spraying anti-sticking structures on the surface of the steel strip, the patterns or the structures by using a spraying device, wherein the patterns or the structures can enable the anti-sticking layers to be better attached to the hot pressing plate, so that the plates and the steel strip are better prevented from being stuck.

Because the structure restriction of continuous press, the user hardly detects out the state of the anti-sticking structure on the steel band directly, so set up on continuous press right anti-sticking structure carries out on-line measuring's detection device, detection device adopts equipment such as laser detection device, can carry out real-time control to anti-sticking structure to the user can directly master anti-sticking structure's state, can be earlier, discover anti-sticking structure's problem sooner, make things convenient for the repair in later stage, prevent effectively because of anti-sticking structure damages the condition that influences the panel quality.

Since the temperature of the heated platens is already high when the continuous press is pressing the sheets, it is generally sufficient to promote rapid curing of the release material. In order to further improve the efficiency of arranging the anti-sticking structure, a curing device for accelerating the curing of the anti-sticking structure can be arranged on the press, and the curing device can adopt an ultraviolet curing device and other equipment.

Utilize the spraying device with antiseized material spraying at the conveyer belt, according to the in-service use effect, can adopt two kinds of schemes to spray antiseized material:

1) continuously carrying out treatments such as spraying, curing and the like before the steel strip enters a working area (before the steel strip is hot-pressed with a plate blank);

2) the whole surface of the steel strip is sprayed and cured before the steel strip works, then the surface coating of the steel strip is continuously detected on line at the specified position of a continuous press, and partial or whole surface of the steel strip is sprayed and cured immediately when the surface coating is found to be poor.

The anti-sticking continuous press has the beneficial effects that:

(1) the adhesion between the plate and the hot pressing plate is prevented through the anti-adhesion structure on the surface of the conveying structure;

(2) utilize detection device to detect the adhesion-preventing structure on the conveyer belt, can in time discover adhesion-preventing structure's problem, make things convenient for follow-up operation, improve the accuracy nature of system.

The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by the present specification, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
