Description

Technical Field

[0001] The utility model relates to an SPC stone plastic floor laminating and defoaming device, belonging to the field of SPC floor manufacturing equipment. Background Art

[0002] Stone plastic flooring is mainly made of composite layers such as stone plastic layer and decorative layer bonded and solidified with each other. The adhesive is mainly phenolic resin. Because the resin has high viscosity and low fluidity, when the resin is coated and the layers of the floor are attached, the air will be retained in the resin due to the viscosity of the resin. If it is not discharged, hollowing will occur inside the stone plastic floor during the curing process and use. The hollowing will cause local deformation of the floor as it expands and contracts with heat, resulting in reduced flatness and even cracking and delamination of the floor. Utility Model Content

[0003] The purpose of the utility model is to overcome the technical problems in the prior art and provide a device that can perform batch lamination and defoaming on SPC stone plastic floors.

[0004] The technical solution adopted by the utility model to solve its technical problems is:

[0005] An SPC stone plastic floor laminating and defoaming device, comprising:

[0006] The housing mechanism includes a cylindrical sealing housing, a cylindrical negative pressure chamber is provided inside the sealing housing, and sealing covers are sealed and fixed at both axial ends of the sealing housing;

[0007] The floor support mechanism includes a plurality of floor inlay frames arranged in an array. The floor inlay frames are arranged in an array within a negative pressure chamber, with outer edges of the floor inlay frames in sealed contact with the inner wall of the negative pressure chamber. A floor inlay opening is provided in the middle of the inlay frame, and an annular floor retaining protrusion is provided on the inner sidewall of the floor inlay opening. A flow guide is provided on both the front and back surfaces of the floor inlay frame. The flow guide includes flow guide grooves arranged in an annular array on the surface of the floor inlay frame, an intermediate groove is provided between the floor inlay opening and the flow guide grooves, and a first connection hole is provided at the bottom of the flow guide groove, which extends through the floor inlay frame.

[0008] A confluence cavity is provided inside the sealing cover, and a plurality of gas collecting grooves corresponding to the guide grooves are provided in a circular array at the bottom of the sealing cover. The gas collecting grooves are connected to the confluence cavity through the second connecting hole. An exhaust valve connected to the confluence cavity is also provided on the sealing cover.

[0009] As a further improvement of the present invention, a rubber extrusion plate is embedded in the middle of the sealing cover, and the extrusion plate is in elastic contact with the floor limiting protrusions of the floor inlay frames at the ends of the floor inlay frame array;

[0010] The extrusion plate can ensure that appropriate extrusion force is applied to the floor, ensuring stable sealing contact between the floor and the floor limiting protrusions.

[0011] As a further improvement of the present invention, the guide groove is a tapered structure, the expanded end of the guide groove is located on the front and back surfaces of the floor mosaic frame, and the contracted end of the guide groove is located at the end of the first connecting hole;

[0012] The guide groove with a tapered structure reduces the pressure drop, increases the air flow rate, and ensures the exhaust efficiency.

[0013] As a further improvement of the present invention, annular sealing rings are embedded on the front and back surfaces of the floor limiting protrusion;

[0014] The sealing ring can ensure the sealing between the edge and the middle of the floor, reduce the volume of the entire negative pressure space, improve the air exhaust efficiency of the floor edge opening, and place the floor glue to expand to the surface of the floor decoration layer.

[0015] As a further improvement of the present invention, a first support sleeve is embedded in the inner wall of the first connecting hole, and a second support sleeve is embedded in the inner wall of the second connecting hole; the first support sleeve and the second support sleeve can be removed and cleaned to reduce the clogging of the first connecting hole and the second connecting hole by phenolic resin and make them difficult to clean.

[0016] As a further improvement of the present invention, the gas collecting tank is provided with an extension portion for covering the middle tank;

[0017] The extension part can improve the gas collection efficiency and reduce the gas collection resistance.

[0018] The beneficial effects of the utility model are:

[0019] The utility model designs a floor fixing structure that can stack and squeeze the floor in an array. At the same time, the array of floors can be vacuumed by setting a diversion structure therein. The glue in the floor can be debubbled by vacuuming. The debubbling efficiency is higher in batch arrangement, and the floor will not be excessively squeezed, thereby ensuring the consistency of the thickness of each floor.
