Description

Technical Field

[0001] The utility model relates to the technical field of SPC floors, in particular to an extrusion molding device for producing SPC floors. Background Art

[0002] SPC flooring is made by extruding PVC base material through an extruder combined with a T-die. The PVC wear-resistant layer, PVC color film and PVC base material are respectively pressed together by a three-roll or four-roll calender. The product is heated and laminated at one time and embossed. The process is simple, and the lamination is completed by heat, without the need for glue.

[0003] Existing public documents include the utility model patent CN220464511U, which discloses an extrusion molding device for SPC floor production, including a machine base, a feeding mechanism, a frame, a hydraulic cylinder, a die, a mold box, and a limiting mechanism. The frame is fixed to one side of the top of the machine base, and the feeding mechanism is fixed to the other side of the top of the machine base. A hydraulic cylinder is fixed to the top of the frame, and the connecting end of the hydraulic cylinder is detachably connected to the die through a clamp and a slot. The mold box is placed on the top surface of the machine base inside the frame. Both sides of the bottom plate of the mold box are provided with limiting grooves. The size of the limiting grooves matches the size of the limiting plates. Both sides of the frame are connected to limiting mechanisms, and the two limiting mechanisms limit the two sides of the mold box. The technical effects achieved are:

[0004] 1. By setting a limiting mechanism, the limiting mechanisms on both sides are used to limit the mold box on the machine base. The mold box is not easily limited during mold pressing. In addition, the limiting plate of the limiting mechanism can be easily moved inward or outward, which is suitable for limiting mold boxes of different sizes.

[0005] 2. Through the setting of the card parts and the card slots, the die can be easily installed or disassembled, which is convenient for replacing the extrusion parts. In addition, the mold box can also be easily replaced, which is suitable for extruding SPC floors of different sizes and improving adjustability.

[0006] The technical solution disclosed in the above patent adopts a method of mutual extrusion between a die and a mold box to realize the molding of SPC. After the SPC floor is molded in the mold box, the molded SPC floor needs to be taken out. Therefore, it can be seen that the main shortcomings of the extrusion molding device for SPC floor production disclosed in the above patent are: it is impossible to achieve continuous production of SPC floor, and the molded SPC floor needs to be continuously taken out, resulting in low production efficiency and insufficient production capacity.

[0035] In the above embodiment, SPC flooring raw materials are added to the interior of extrusion box a1 and then continuously extruded and conveyed into transition plate b1 by screw conveyor a2. Subsequently, under the continuous extrusion force, the SPC flooring raw materials inside transition plate b1 gradually enter the forming hole c3 between the upper mold plate c1 and the lower mold plate c2 to be formed, thereby achieving continuous extrusion molding of the SPC flooring and improving production efficiency. Cover plate 1 a4 and cover plate 2 b2 are respectively covered on the top sides of extrusion box a1 and transition plate b1, and cover plate 1 a4 and cover plate 2 b2 are connected by connecting plate d.
