Embodiment one

As shown in Figures 1 and 2, a wood-plastic furniture board processing equipment includes:

Extrusion cutting assembly 1;

A penetration component 2 arranged at the extrusion end of the extrusion cutting component 1;

The profiling assembly 3 arranged on both sides of the extrusion cutting assembly 1; and

Driving the driving assembly 4 that drives the penetration assembly 2 to move back and forth toward the pressing assembly 3;

The extrusion cutting assembly 1 inserts the extruded wood-plastic perforation into the penetration assembly 2, and cuts it equidistantly. The driving assembly 4 sends the cut plate supported by the penetration assembly 2 to the pressing assembly 3, and the pressing assembly 3 When the truncated plate is bent, it will perform synchronous cooling inside and outside of the plate with the penetration component 2 .

Through the above content, it is not difficult to find that in the process of wood-plastic furniture processing, it is necessary to extrude the wood-plastic board, and according to the assembly or installation requirements of the furniture, the extruded wood-plastic board is bent into the shape of the demand curve, and then installed or installed. Assembled and used, but in the bending and forming process of wood-plastic panels, in order to save materials, wood-plastic panels are often processed into hollow panels, that is, wood-plastic perforations arranged side by side are reserved on the panels, and in this type of perforated When the plate is bent and deformed, it is easy to cause irregular deformation of the perforation on the wood-plastic plate due to the bending deformation, which leads to uncontrollable thickness of the bent and deformed part, and the cooling effect is poor during the bending process. In the case of heat dissipation, removal of the press molding equipment is prone to re-deformation to varying degrees.

In the present invention, the wood-plastic raw material is extruded into a wood-plastic plate by using the extrusion cutting assembly 1, and during the extrusion process, the perforation of the extrusion part will correspond to the penetration assembly 3, and the penetration assembly 3 will continue to Penetrating into the perforation, after penetrating to a predetermined depth, the extruding and cutting assembly 1 controls to divide the board extruded to a predetermined length, and after cutting and separating, the wood-plastic board inserted on the piercing assembly 3 will be driven Under the action of the power of component 4, it is transferred to the profiling component 3, and the profiling component 3 will carry out the bending and pressing process on the transferred wood-plastic plate, and in the process of bending and pressing, by using the interspersed component 3 to the wood-plastic When the wood-plastic plate is pressed by the pressing component 3, the perforation on the plate will also rotate with the bending of the wood-plastic plate, and the penetration component 2 can be used to pad the perforation when the wood-plastic plate is bent, so as to avoid bending The deformation of the wood-plastic plate in the part toward the perforation is too large, which seriously affects the thickness uniformity of the wood-plastic plate; and, when the profiling component 3 bends the wood-plastic plate, it will cool the wood-plastic plate, and During cooling, the wood-plastic panel exterior and the perforated interior are simultaneously cooled together with the penetration assembly 3, thereby improving the uniformity and rapidity of cooling the wood-plastic panel.

When the extruded plate is extruded to the penetration component 2 to reach a predetermined length, the power split component 12 moves to cut and separate along the width direction of the plate, and the penetration component 2 of the other group completes the pressure forming process preparation Moving towards the extrusion cutting assembly 1, continue to penetrate the wood-plastic sheet;

Step 4, profiling processing, the cut board will follow the driving force of the driving component 4 to the profiling component 3 under the penetration of the intersecting component 2, and the pushing component 33 exerts a driving force on the press seat 31, so that the press seat 31 moving towards the surface of the sheet;

Step 5. Spray water to cool down. When the pressure seat 31 moves towards the surface of the plate, the inlet 32 of the pressure seat 31 and the cold treatment component 22 on the penetration component 2 will spray water on the outer wall of the plate and the inner wall of the perforation respectively until the pressure seat 31 arrives. plate surface;

Step 6: Exhaust air to dissipate heat. After the press seat 31 reaches the surface of the plate, the press seat 31, driven by the pushing assembly 33, continues to extrude the plate in both directions according to the predetermined bending method, and during the extrusion process and the pressing process, through The cold treatment component 22 and the inlet channel 32 respectively perform air extraction on the perforation and the outer wall of the plate to improve the efficiency of simultaneous heat dissipation inside and outside;

Step 7. Perforation support. When the press seat 31 is extruded and bent, the pulling assembly 23 releases the support seat 21, and the support seat 21 arranged in the perforation performs adaptive rotation following the bending direction of the plate, and props up the bending part corresponding to the perforation Inner wall, to avoid a large shrinkage of the perforated inner wall towards the perforated space.
