Description

Technical Field

[0001] This invention relates to the field of flooring production equipment technology, specifically to a large-format mortise and tenon reverse-hanging patterned board and a hot press plate for mortise and tenon steam exhaust. Background Technology

[0002] Currently, when pressing patterns onto the surface of engineered wood panels, the patterned panels are generally suspended on the lower surface of the upper layer of flat panels. When the panel size is small, the patterned panels sag less due to gravity. However, when the panel size is large, especially extra-large panels, the sag is extremely large, particularly noticeable in the middle. This can lead to uneven pressure on the panel blank, affecting the flatness of the finished product and the quality of the surface pattern formation. On the other hand, the production of extra-large engineered wood panels is constrained by ventilation. The current solution is to cut a slit along the center line of the entire panel to leave a ventilation channel. However, this method increases the need for edge trimming and reduces material utilization. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of the aforementioned background technology by providing an extra-large format mortise-groove reverse-hanging patterned plate and a hot press plate with mortise-groove steam exhaust, which reduces the problem of sagging in the middle of large format patterned plates, reduces material waste, and ensures steam exhaust.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A large-format mortise-groove reverse-hanging patterned plate and a mortise-groove steam venting hot press plate includes a hot press plate body and a patterned plate body distributed vertically. The hot press plate body and the patterned plate body are connected by a suspension lug and a screw and nut structure. The key feature is that the lower surface of the hot press plate body is provided with at least one mortise, and the back of the patterned plate body is provided with a tenon that matches the mortise. After the tenon is inserted into the mortise, the gap between the tenon and the mortise is maintained at 1-1.5mm. When the hot press plate body and the patterned plate body are connected, the gap between them is maintained at 1-1.5mm. The tenon is provided with a T-shaped through hole for steam venting.

[0005] A further improvement of the present invention, which is a large-format mortise-groove reverse-hanging patterned plate and a hot press plate for mortise-groove steam exhaust, is that the length direction of the mortise and the length of the tenon are the same as the inlet and outlet directions of the hot press plate.

[0006] A further improvement of the present invention, which is a large-format mortise and groove reverse hanging pattern plate and a mortise and groove steam exhaust hot press plate, is that the width of the mortise is 5-20mm, the height is 5-10mm, and the length extends through the length direction of the hot press plate body.

[0007] A further improvement of the extra-large format mortise and tenon reverse hanging pattern plate and mortise and tenon exhaust hot press plate of the present invention is that the mortise and tenon cross sections are wedge-shaped with a larger upper section and a smaller lower section, and the corners are chamfered.

[0008] A further improvement of the extra-large format mortise-groove reverse-hanging patterned plate and the hot press plate with mortise-groove steam exhaust is that the mortise is located on the longitudinal center line of the hot press plate body, the tenon is located on the longitudinal center line of the patterned plate body, the through hole is located at a position lower than the upper surface of the tenon, and the blind hole in the vertical direction of the T-shaped through hole is larger than the through hole in the horizontal direction.

[0009] A further improvement of the present invention, a large-format mortise and tenon reverse hanging pattern plate and a mortise and tenon exhaust hot press plate, is that the mortise and tenon are provided in multiple sets, with an odd number, and the central tenon is provided with a through hole.

[0010] A further improvement of the extra-large format mortise-groove reverse hanging pattern plate and mortise-groove steam venting hot press plate of the present invention is that a pad is provided above the hot press plate body. The lower surface of the pad is provided with a left-directing T-shaped through hole group and a right-directing T-shaped through hole group. The through hole group has an inverted U-shaped arc cross section, including a longitudinal semi-circular groove and a transverse semi-circular groove. The top of the longitudinal semi-circular groove is provided with a vertical through hole, and the vertical through hole keeps the longitudinal center line of the pad facing the longitudinal center line of the hot press plate body.

[0011] A further improvement of the extra-large format mortise and groove reverse hanging pattern plate and mortise and groove steam exhaust hot press plate of the present invention is that the transverse semicircular groove is provided with multiple sets, and the transverse semicircular groove of the left-direction T-shaped through hole group is longitudinally offset from the transverse semicircular groove of the right-direction T-shaped through hole group.

[0012] A further improvement of the present invention, which is a large-format mortise and groove reverse hanging patterned plate and a mortise and groove steam exhaust hot press plate, is that the dimensions of the hot press plate body and the patterned plate body are 8920×4960 (length), 8920×2580 (length), 6200×4960 (length), 6200×2800 (length), and 3100×2580 (length).

[0013] Compared with the prior art, the beneficial effects of the present invention are: This invention, by setting a suspended patterned plate with a tenon, prevents the plate from sagging in the middle even when it is large in size, thus ensuring the flatness of the product and the quality of the surface pattern. On the other hand, the tenon structure is provided with a through hole for venting steam, and the left-hand and right-hand through-holes on the pad plate provide stable venting, avoiding the center saw cut of the entire plate and ensuring continuous, convenient and stable production.

Detailed Implementation

[0016] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0018] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0019] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0020] like Figure 1 As shown, a large-format mortise-groove reverse-hanging patterned plate and mortise-groove steam venting hot press plate includes a hot press plate body 1 and a patterned plate body 2 distributed vertically. The hot press plate body and the patterned plate body are connected by suspension lugs and screw and nut structures 3. The connection method between the hot press plate body and the patterned plate body is existing technology. At least one mortise 5 is provided on the lower surface of the hot press plate body, and a tenon 6 adapted to the mortise is provided on the back of the patterned plate body. After the tenon is engaged in the mortise, the gap between the tenon and the mortise is maintained at 1-1.5mm. When the hot press plate body and the patterned plate body are connected, the gap between them is maintained at 1-1.5mm. That is, in the first state (no load) of the hot press, the patterned plate and the plate should maintain a gap of 1-1.5mm, and the tenon and the mortise should also maintain a gap of 1-1.5mm; Figure 2 As shown, in the second state (load closed) of the hot press, the patterned plate and the flat plate are tightly fitted, and the tenon and the mortise are tightly fitted. A gap is maintained to allow for thermal expansion and contraction during heating of the flat plate. The tenon has a T-shaped through hole 7, the vertical part of which passes through the patterned plate body and is used for steam venting. Multiple sets of through holes are evenly spaced along their length.

[0021] Specifically, the length of the mortise and the length of the tenon are in the same direction as the inlet and outlet of the hot press plate. The mortise width is 5-20mm, the height is 5-10mm, and its length extends through the length of the hot press plate body. The mortise and tenon cross-sections are wedge-shaped, wider at the top and narrower at the bottom, with chamfered edges to avoid stress concentration.

[0022] The mortises on the hot press plate body can be machined by a special milling cutter. The tenons of the patterned plate must be laser welded to the outer corner seam and laser plug welded to the inner hole, that is, the inner side is welded to the patterned plate through the plug welding hole 14. Welding the back of the patterned plate will have an adverse effect on the pattern on the front. The ideal approach is to weld the tenons first, and then perform oil grinding, etching, electroplating and other processes on the surface of the patterned plate.

[0023] Furthermore, the mortise is located on the longitudinal centerline of the hot press plate body, the tenon is located on the longitudinal centerline of the patterned board body, and the through hole is located below the upper surface of the tenon. The vertical blind hole of the T-shaped through hole is larger than the horizontal through hole. That is, when only one set of mortise and tenon is designed, it must be designed at the longitudinal centerline, and multiple T-shaped through holes should be set at a position slightly below the upper surface of the tenon. The spacing of the through holes should not be too large or too small. If it is too large, it will reduce the steam exhaust speed; if it is too small, it will affect the planarity of the patterned board. The vertical direction of the T-shaped through hole will inevitably leave a hole imprint on the surface of the artificial board. At the longitudinal centerline, the hole imprint can be removed with a center saw.

[0024] Furthermore, multiple sets of tenons and mortises can be provided, with an odd number of them, and a through hole on the central tenon. That is, when there is more than one tenon on the back of the patterned board, it should generally be an odd number, and it is best to maintain the symmetry of the center line. Only the tenon at the center line is provided with a T-shaped through hole, and the other tenons are only used to hang the patterned board.

[0025] Furthermore, such as Figure 6 , Figure 10 , Figure 11 As shown, a pad 4 is provided above the hot press plate body. The lower surface of the pad is provided with a left-directing T-shaped through hole group and a right-directing T-shaped through hole group. The cross-section of the through hole group is an inverted U-shaped arc, that is, the through hole group includes a longitudinal semi-circular groove 9 and a transverse semi-circular groove 8. The top of the longitudinal semi-circular groove is provided with a vertical through hole 10. The vertical through hole keeps the longitudinal center line of the pad facing the longitudinal center line of the hot press plate body.

[0026] Furthermore, the transverse semicircular grooves are provided in multiple sets, with the transverse semicircular grooves of the left-facing T-shaped through-hole group longitudinally offset from those of the right-facing T-shaped through-hole group. The left and right directions must be offset; they cannot be set on a single straight line in the transverse direction to avoid the pad plate breaking under stress.

[0027] Furthermore, such as Figure 4 , Figure 7 As shown, a second longitudinal semicircular groove 11 is provided above the platen body of the hot press, corresponding to the longitudinal semicircular groove position of the pad, to increase the through area and accelerate steam exhaust.

[0028] Furthermore, such as Figure 8 and Figure 9 As shown, a convex back 12 is provided above the pad, and several T-shaped left and right through holes 13 are provided at the position where the convex back is close to the pad, parallel to the pad, to increase the exhaust area.

[0029] like Figure 12 As shown, two sets of second longitudinal semicircular grooves are added to the platen body of the hot press, distributed on both sides of the original second longitudinal semicircular grooves. Several second transverse semicircular grooves are arranged at intervals between the connected second longitudinal semicircular grooves. The addition of second longitudinal semicircular grooves prevents the pad plate from being misaligned and unable to align with the center seam. A second longitudinal semicircular groove is added to each side of the center seam and they are interconnected, thus widening the area of ​​the steam exhaust channel.

[0030] like Figure 13 As shown, the upper end of the convex back 12 is pointed, the lower part is a straight section, and the T-shaped left and right through holes are located at the lower part.

[0031] Furthermore, such as Figure 14 As shown, the horizontal section of the T-shaped left and right through hole group 13 can be composed of two sets of inclined sections 16 to avoid the through hole being blocked.

[0032] Specifically, the dimensions of the hot press plate body and the patterned plate body can be, but are not limited to, 8920×4960, 8920×2580, 6200×4960, 6200×2800, or 3100×2580.

[0033] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the invention. In particular, as long as there is no structural conflict, the features in the disclosed embodiments can be combined with each other in any manner. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
