Definitions
- thermo tiles namely to 5 folding form with a cutting element, allowing you to cut the molded product (thermal tile), from a continuous tape located on the form.
- a known form for the manufacture of tiles disclosed in WO 97/02122 A1, publ. 01/23/19997.
- the form is made in the form of a pallet.
- an extruder passes, which extrudes a continuous belt, which is located on the forms and moves along a conveyor.
- Cutting products is carried out with a cutting tool at the corner parts of the form.
- the disadvantage of the known form is that the accuracy of the cutting tool 15 depends on the accuracy of the mechanisms of the feeding (positioning) Form made in the form of a pallet, and the possibility of cutting only the angular parts of the form, which leads to marriage when cutting products.
- collapsible form for the manufacture of tiles disclosed in SU 102808 A1, publ. 06/10/1996.
- Collapsible form for the manufacture of 20 tiles consists of two separate parts, with the assembly of the incoming one to another.
- the disadvantage of the folding form is the absence of a knife for cutting, which is part of the form located on the form, on which the product is first formed, and then the cutting and low productivity 25 in the manufacture of tile.
- the objective of the claimed invention is to develop a collapsible form with a cutting element for the manufacture of thermal tile.
- the technical result of the invention is to improve the accuracy of cutting the product with the independence of the mechanisms of the form in the cutting zone.
- the lower (1) and upper (2) forming parts of the mold are made of a material with high thermal conductivity (aluminum and its alloys, and the cutting element (3) is made of a hard-alloy material (steel).
- a cut-out is made the perimeter coinciding along the perimeter with the outer surface of the lower (1) forming part of the mold.
- the cutting element (3) is made in the form of a plate with a notch coinciding along the perimeter with the outer surface of the lower (1) forming part of the form and is rigidly fixed on the upper (2)
- thermoplastic polymeric material poly (ethylene terephthalate) (PET) or polyvinyl chloride (PVC)
- PET poly (ethylene terephthalate)
- PVC polyvinyl chloride
- sheets are laid in shape and the shape of a tile made of a thermoplastic polymer material is given to a preliminarily softened sheet of a thermoplastic polymer material by simultaneously acting on a sheet of a thermoplastic polymer material on the one hand and a vacuum on the other hand, with vacuum simultaneously It removes the remaining air from the cavities of the mold, which makes it possible to obtain a product with a uniform thickness and exact geometry of the shape repeating the geometry.
- the simultaneous impact on the sheet of a thermoplastic polymer material of high pressure on the one hand and a vacuum on the other hand does not allow breaking the tape of thermoplastic polymer material and form further along
- the 35 conveyor move along with a continuous tape of thermoplastic polymeric material, which is pressed to the form and repeats its geometry. Then the mold is filled with a two-component polyurethane foam (PUF) on the surface of a tape of a thermoplastic polymer material. Further, the form with molded tiles filled with polyurethane foam falls on the 5th conveyor consisting of two tapes, the lower (carrying and pulling) tape and the upper clamping tape providing the clamping of the protective film of PET or metallized PET or PVC automatically drawing from the roll and protecting the tape of the upper clamping conveyor from contact with a two-component foam. At the same time, the PET film or the metallized PET or PVC is opposite, relative to the formed sheet, surface.
- PPF polyurethane foam
- a product is formed in the form between two tapes, inside of which PUF is located, the two tapes form the “shell” of the product.
- the length of the conveyor is designed so that the form with the product filled with polyurethane foam is sandwiched between two belts for
- the conveyor moves discretely, synchronously with the cycles of the molding zone. After passing through the entire length of the conveyor, the mold with the product molded from the polymer, filled with polymerized two-component foam, gets onto the workbench of a punching machine installed perpendicular to the line of movement of the molds
- the width of the working table of the press is twice the width of the form, which ensures that the impact plate of nylon rigid plates hits, regardless of the accuracy with which the conveyor forms are fed to the working table.
- the cyclical nature of the press work is related to the molding work cycle. Knife located on the surface of the mold and moving along with the form in contact with the shock
- a plate of rigid nylon materials chops off / separates the form with the product molded in it, filled with polymerized polyurethane foam, from the sheet of endless tape of thermoplastic polymer material and protective tape around the perimeter of the inner surface of the form, i.e. the upper edge of the product is cut from an endless belt from a thermoplastic resin of a polymeric material and a protective tape.
- the sheet remains after cutting the product are wound on the coiling device and then go to the crusher for further preparation for reuse.
- the form with the product inside comes to the opening section of the upper part of the form, where the form is opened and the finished product is taken out of it. Further the form is closed and on the conveyor z return forms back to the site molding. Using a sufficient number of forms allows you to make the process continuous.
