Description

Technical Field

[0001] The utility model belongs to the technical field of wood-plastic processing, in particular to a high-speed extrusion embossing device for wood-plastic composite materials. Background Art

[0002] In the single-sided embossing process of embossed wood-plastic composite materials, the profile is embossed with a heated roller on the top and a shaping mold is installed on the bottom for shaping. To ensure clear embossing patterns, the pressure of the heated roller on the profile is bound to be greater. The force is mutual, and the pressure between the profile and the shaping mold will be equally large. Because the top of the profile is in contact with the roller, the contact point is a line, and the bottom is in contact with the shaping mold, the contact point is a surface, resulting in much greater resistance at the bottom of the profile than at the top. When the extrusion speed is too fast, the different upper and lower resistances will lead to different discharge speeds, resulting in abnormal problems such as blocking, which seriously affects product quality and operation stability.

The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0023] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0024] The embodiment of the utility model provides a high-speed extrusion embossing device for wood-plastic composite materials, such as Figure 1-Figure 3 As shown, the high-speed extrusion embossing device for wood-plastic composite materials is applied to the front end of an extruder. The front end of the extruder is provided with a mold 1 and a mold die 2. The mold die 2 is arranged on the mold 1. The wood-plastic composite board 12 leaves the extruder from the mold die 2 and enters the high-speed extrusion embossing device for wood-plastic composite materials. The high-speed extrusion embossing device for wood-plastic composite materials comprises:

[0025] The roller bracket 6 is provided with an embossing roller 8 and a smooth soft roller 9. The embossing roller 8 is provided with a heating coil inside. The outer surface of the embossing roller 8 is provided with a pattern for embossing. The wood-plastic composite board 12 extruded from the die 1 of the extruder reaches between the embossing roller 8 and the smooth soft roller 9. The embossing roller 8 acts on the surface of the wood-plastic composite board 12. At this time, the embossing roller 8 is in a high temperature environment, and the pattern will form a specific pattern on the surface of the wood-plastic composite board 12. The smooth soft roller 9 is made of a material with a Rockwell hardness of 55-60. The smooth soft roller 9 is used to support the side of the wood-plastic composite board 12 away from the embossing roller 8;

[0026] The arc-shaped ear brackets 3 are provided in two groups and are arranged in parallel between the embossing roller 8 and the smooth soft roller 9. The arc-shaped ear brackets 3 form a shaping guide groove, and the wood-plastic composite board 12 moves along the shaping guide groove between the arc-shaped ear brackets 3. The arc-shaped ear brackets 3 help the smooth soft roller 9 to shape the wood-plastic composite board 12, thereby preventing the rolling and squeezing between the embossing roller 8 and the smooth soft roller 9 from causing deformation of the side wall of the wood-plastic composite board 12, thereby affecting the quality of the wood-plastic composite board 12.

[0027] In the present application, the arc-shaped shaping ear bracket 3 and the smooth soft roller 9 replace the shaping mold in the prior art for support, so that the bottom of the wood-plastic composite board 12 is also in contact with the roller, reducing the upper and lower resistance difference to avoid abnormal problems such as blockage caused by different discharge speeds. The arc-shaped shaping ear bracket 3 is used to complete the shaping support of the side wall of the wood-plastic composite board 12, ensuring that the wood-plastic composite board 12 can successfully complete the shaping action;

[0028] The arc-shaped ear support 3 is provided with an upper arc surface 31 and a lower arc surface 32. The upper arc surface 31 is adapted to the curvature of the embossing roller 8, and the lower arc surface 32 is adapted to the curvature of the smooth soft roller 9. The upper arc surface 31 and the lower arc surface 32 accommodate the embossing roller 8 and the smooth soft roller 9, respectively. When the height of the arc-shaped ear support 3 is greater than the wood-plastic composite board 12, in order to ensure that the embossing roller 8 and the smooth soft roller 9 can act on the wood-plastic composite board 12 during extrusion;

[0029] The arc-shaped ear bracket 3 is provided with protrusions and grooves adapted to the side walls of the wood-plastic composite board 12. The protrusions and grooves are used to support the side walls of the wood-plastic composite board 12. The appropriate structure will be selected according to the side wall structure of the wood-plastic composite board 12. For example, when the side wall of the wood-plastic composite board 12 is a groove structure, the arc-shaped ear bracket 3 is provided with protrusions. If the side wall of the wood-plastic composite board 12 is a convex structure, the arc-shaped ear bracket 3 is provided with grooves.

[0030] The roller bracket 6 is also provided with a bearing seat (not shown in this application) for supporting the rotation of the embossing roller 8 and the smooth soft roller 9. The embossing roller 8 and the smooth soft roller 9 are rotatably connected to the roller bracket 6. The embossing roller 8 and the smooth soft roller 9 rotate during the movement of the wood-plastic composite board 12.

[0031] As a preferred implementation in this embodiment, the arc-shaped ear-forming bracket 3 and the smooth soft roller 9 are further provided with a circulating cooling system, and the roller bracket 6 is further provided with a temperature controller 7;

[0032] The interior of the smooth soft roller 9 is hollow, and a soft roller water inlet pipe 10 and a soft roller water outlet pipe 11 for connecting circulating cooling water are respectively provided at both ends of the smooth soft roller 9. The soft roller water inlet pipe 10 and the soft roller water outlet pipe 11 are connected to the hollow part of the interior of the smooth soft roller 9;

[0033] The arc-shaped ear bracket 3 is hollow inside, and a bracket water inlet pipe 4 and a bracket water outlet pipe 5 are respectively provided at both ends of the arc-shaped ear bracket 3, and the bracket water inlet pipe 4 and the bracket water outlet pipe 5 are connected to the interior of the arc-shaped ear bracket 3;

[0034] The bracket water inlet pipe 4 and the bracket water outlet pipe 5 and the soft roller water inlet pipe 10 and the soft roller outlet pipe 11 are all connected to the external circulating cooling water system, and the cooling water is used to flow inside the arc-shaped ear bracket 3 and the smooth soft roller 9, so that the cooling water keeps the arc-shaped ear bracket 3 and the smooth soft roller 9 at a relatively low temperature, thereby preventing the arc-shaped ear bracket 3 and the smooth soft roller 9 from heating up and causing adhesion with the wood-plastic composite board 12, affecting the forming effect of the wood-plastic composite board 12;

[0035] In this embodiment, the temperature controller 7 mainly displays the surface temperature of the embossing roller 8, the water temperature of the bracket outlet pipe 5, and the water temperature of the soft roller outlet pipe 11, helping the operator to adjust the process accordingly according to the temperature conditions during the embossing process;

[0036] As a preferred implementation in this embodiment, the embossing roller 8 and the smooth soft roller 9 are staggered, and the upper arc surface 31 and the lower arc surface 32 are also staggered.

[0037] In this embodiment, the staggered arrangement of the embossing roller 8 and the smooth soft roller 9 can avoid the difference in width between the upper and lower dimensions of the plate;
