Description

Technical Field

[0001] This invention relates to a flooring processing technology, and more particularly to a process and apparatus for laying a composite paint film on the flooring surface. Background Technology

[0002] Flooring manufacturers often have a large amount of unusable waste material, such as discs, ends, and short boards, during the production process, which reduces the utilization rate of wood. To address this issue, patent 202321676781.7 discloses a composite flooring method. This method involves sawing and gluing these wood waste materials to form large composite boards through splicing. These boards are then veneered, thus utilizing the waste material while improving the aesthetics of the finished composite flooring.

[0003] However, a problem in the actual processing of this composite flooring is that, in order to effectively utilize waste materials, the composite board needs to be glued together from multiple blanks made of different raw materials. Due to differences in the species, density, and other properties of the raw materials, the expansion and contraction rates of the different blanks also vary. This means that when the flooring expands or contracts due to external environmental influences, the expansion and contraction ranges between the different blanks will also differ, causing mutual pulling between the blanks. This not only increases the possibility of flooring deformation and cracking but also easily leads to the surface panel detaching or tearing under stress.

[0004] Therefore, existing composite flooring made from multiple wood waste materials suffers from poor structural stability. Summary of the Invention

[0005] The purpose of this invention is to provide a process and apparatus for laying composite paint films on floor surfaces. This improves the structural stability of the flooring and facilitates processing by manufacturers.

[0006] The technical solution of this invention: a process for laying a composite paint film on a floor surface, comprising the following steps:

[0007] ① Several blanks are glued together to form a large-sized composite board after gluing, resulting in board A;

[0008] ② Sawing and sanding the surface of board A to achieve the specified dimensions and thickness after processing, thus obtaining board B;

[0009] ③ Multiple horizontal grooves are made on the surface of plate B to obtain plate C;

[0010] ④According to 40~60g / m 2 The amount of coating is such that a UV-cured resin layer is coated on the surface of board C, and the UV-cured resin layer completely fills the transverse groove after coating, thus obtaining board D;

[0011] ⑤ After gluing the panel and multiple ribs together, form the E1 board. Then, lay the E1 board on the surface of the D board so that the light-cured resin layer on the surface of the D board is completely bonded to the panel. The lower end of the rib passes through the light-cured resin layer and interlocks with the horizontal groove. There is a gap between the two sides of the rib and the side wall of the horizontal groove to obtain the E board.

[0012] ⑥ Hot-press the E board to bond and fix the panel, ribs and composite board together after hot pressing, to obtain the F board;

[0013] ⑦ After applying glue to the back of board F, glue the back plate to the back of board F and fix it by hot pressing to obtain board G.

[0014] ⑧ Cut the G board into several small floor blanks to obtain finished boards.

[0015] In the aforementioned laying process based on a composite paint film on the floor surface, the blank board in step ① is long and narrow, and the horizontal groove in step ③ is perpendicular to the length direction of the blank board. After the horizontal groove is opened, it passes through multiple blank boards at the same time.

[0016] The device also includes a mounting apparatus, wherein the E board in step ⑤ is hot-pressed into shape by the mounting apparatus. The mounting apparatus includes a conveyor roller, on which a hot-pressing fixture for installing the panel, ribs and composite board is placed. A hot-pressing mechanism for hot-pressing the board is provided above the hot-pressing fixture. The hot-pressing fixture includes a base plate, with vertical guide rods connected around the base plate. A pressure plate is slidably connected to the guide rods. A first elastic element located between the base plate and the pressure plate is sleeved on the outside of the guide rods. Fasteners are detachably connected to both sides of the pressure plate. Several fastening grooves for fastening and connecting the ribs are distributed at intervals on the fasteners. An extrusion piece for slidably connecting the fastener is provided on one side of the fastener groove. The end of the extrusion piece extends to the outside of the fastener and is connected to a positioning strip. The two ends of the positioning strip are slidably connected to the bottom of the pressure plate via a sliding rod. A second elastic element sleeved on the outside of the sliding rod is provided between the positioning strip and the pressure plate. A driving element is connected to the outside of the positioning strip. A driving groove for cooperating with the driving element is provided on the base plate. A locking body for cooperating with the positioning strip is provided on the pressure plate.

[0017] In the aforementioned laying device, the lock body is a spring pin detachably connected to the pressure plate. The spring pin includes a pin frame, an L-shaped pin slidably connected to the pin frame, and a first stop and a second stop respectively located inside the pin frame. The first stop and the second stop are arranged vertically along the height direction on the pin. A third elastic element is connected between the first stop and the pin frame. The lower end of the pin frame has a through hole that matches the second stop. The bottom of the pin extends to the bottom of the pin frame and has a third stop. The positioning strip has a groove that matches the third stop.

[0018] In the aforementioned installation device, the panel is fastened to the pressure plate by ribs, the outer wall of the panel is in contact with the side wall of the fastener, and the end of the rib extends to the outer side of the panel and is fastened to the fastener groove.

[0019] In the aforementioned paving device, the upper end of the driving component is detachably connected to a positioning strip, and the bottom of the driving component extends below the positioning strip and is provided with a roller that engages with the driving groove.

[0020] In the aforementioned laying device, the base plate is detachably connected with baffles around its perimeter for horizontally limiting the composite board, and the bottom ends of the pressure plate are detachably connected with baffles for longitudinally limiting the panel.

[0021] Compared with the prior art, the present invention has the following characteristics:

[0022] (1) The present invention uses the structural cooperation of transverse groove and rib to enable the rib to limit the position of each blank plate connected to it after insertion, thereby alleviating the difference in amplitude of different blank plates during expansion and contraction and improving the structural stability of the composite board; the photocurable resin layer set between the panel and the composite board can also form a buffer after curing, reducing the possibility of panel cracking; by fastening the panel and the composite board together after applying glue, the connection stability between the panel and the composite board can be further improved, thereby reducing the possibility of separation of the three.

[0023] (2) By setting the gap between the rib and the transverse groove, the composite panel can deform in the direction of the transverse groove during the expansion and contraction process, thereby releasing the deformation force of the composite panel and reducing the possibility that the composite panel will directly apply the deformation force to the panel through the rib.

[0024] (3) By optimizing the structure of the installation device, the panel and ribs can be installed on the hot pressing fixture before hot pressing, and the relative positions of the panel, ribs and composite board are limited by the hot pressing fixture, thereby effectively improving the fastening effect of the ribs and cross grooves during hot pressing; on this basis, by optimizing the structure of the hot pressing fixture, it can squeeze and limit the ribs and composite board before hot pressing to ensure their positioning effect; after the panel, ribs and composite board are hot pressed and formed, the pressure plate can separate from the panel and ribs, thereby releasing the squeezing and limiting effect on them, and improving the forming effect and stability of the floor;

[0025] (4) By optimizing the connection structure between the lock body and the positioning bar, the positioning bar can drive the pin to rotate during the opening process, and the pin moves downward to limit the positioning bar after rotating into place, thereby preventing the positioning bar from re-contracting after opening; with the above cooperation, on the one hand, the panel and rib can be unlocked, and on the other hand, the positioning bar can avoid being subjected to the squeezing force from the lock body in the height direction during the transmission process, that is, to ensure the lateral stability of the positioning bar and prevent jamming.

[0026] Therefore, this invention can improve the structural stability of the floor and facilitate the manufacturing process. Attached Figure Description

Detailed Implementation

[0038] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0039] Example. A process for applying a composite coating film to a floor surface includes the following steps:

[0040] ① Several blanks are glued together to form a large-sized composite board 300 after gluing, resulting in board A;

[0041] ② Sawing and sanding the surface of board A to achieve the specified dimensions and thickness after processing, thus obtaining board B;

[0042] ③ Multiple horizontal grooves of 400 are made on the surface of plate B to obtain plate C;

[0043] ④According to 40~60g / m 2 The amount of coating is such that a UV-cured resin layer is coated on the surface of plate C, and the UV-cured resin layer completely fills the transverse groove 400 after coating, thus obtaining plate D.

[0044] ⑤ After bonding the panel 100 and multiple ribs 200 together, an E1 board is formed. Then, the E1 board is laid on the surface of the D board, so that the light-cured resin layer on the surface of the D board is completely bonded to the panel 100, and the lower end of the rib 200 passes through the light-cured resin layer and interlocks with the transverse groove 400. A gap is left between the two sides of the rib 200 and the side wall of the transverse groove 400 to obtain the E board.

[0045] ⑥ The E board is subjected to hot pressing treatment, so that the panel 100, rib 200 and composite board 300 are bonded and fixed together after hot pressing to obtain the F board;

[0046] ⑦ After applying glue to the back of board F, glue back plate 500 to the back of board F and heat press to fix it, thus obtaining board G.

[0047] ⑧ Cut the G board into several small floor blanks, and then remove the excess material at the edges of the G board to obtain the finished board.

[0048] The blank in step ① is long and narrow. The transverse groove 400 in step ③ is perpendicular to the length direction of the blank. After the transverse groove 400 is opened, it passes through multiple blanks at the same time.

[0049] The laying device, wherein board E in step ⑤ is hot-pressed and formed by the laying device; the laying device is configured as follows: Figure 1 As shown, the device includes a conveyor roller conveyor 1, on which a hot pressing fixture for installing the panel 100, ribs 200, and composite board 300 is placed. Above the hot pressing fixture is a hot pressing mechanism 2 for hot pressing the boards. The hot pressing mechanism 2 is a conventional hot pressing equipment for composite multilayer boards. The hot pressing fixture includes a base plate 3, with vertical guide rods 4 connected around the base plate 3. A pressure plate 5 is slidably connected to the guide rods 4. A first elastic element 6 is sleeved on the outside of the guide rods 4, located between the base plate 3 and the pressure plate 5. Both the base plate 3 and the pressure plate 5 are provided with guide sleeves for accommodating and limiting the first elastic element 6. The two sides of the pressure plate 5 are detachable. The fastener 7 is connected by a buckle strip 7, which has several buckle grooves 8 spaced apart for fastening the connecting ribs. One side of the buckle groove 8 is provided with a pressing piece 9 for sliding connection of the buckle strip 7. The end of the pressing piece 9 extends to the outside of the buckle strip 7 and is connected to a positioning strip 10. The two ends of the positioning strip 10 are slidably connected to the bottom of the pressure plate 5 via a slide rod 11. A second elastic element 12 is provided between the positioning strip 10 and the pressure plate 5 and is sleeved on the outside of the slide rod 11. A driving element 13 is connected to the outside of the positioning strip 10. The bottom plate 3 is provided with a driving groove 14 that cooperates with the driving element 13. One side wall of the driving groove 14 forms an inclined guide surface. The pressure plate 5 is provided with a lock body that cooperates with the positioning strip 10.

[0050] The lock body is a spring pin detachably connected to the pressure plate 5. The spring pin includes a pin frame 15, on which an L-shaped pin 16 is slidably connected. The pin 16 is provided with a first stop 17 and a second stop 18 located inside the pin frame 15. The first stop 17 and the second stop 18 are arranged vertically along the height direction on the pin 16. A third elastic member 19 is connected between the first stop 17 and the pin frame 15. The lower end of the pin frame 15 is provided with a through hole 20 that matches the second stop 18. The bottom of the pin 16 extends to the bottom of the pin frame 15 and is provided with a third stop 21. The positioning strip 10 is provided with a groove 22 that matches the third stop 21. The width of the groove 22 is greater than the outer diameter of the pin 16 and less than the length of the third stop 21. The first stop 17, the second stop 18 and the third stop 21 are all round rods that are inserted into the pin 16.

[0051] The first stop 17 is a bent metal wire, and the bending angle of the metal wire can be manually adjusted by the operator; when the spring pin is in the initial state, the metal wire of the first stop 17 and the side wall of the pin holder 15 are in contact with each other.

[0052] The panel 100 is fastened to the pressure plate 5 by the rib 200. The outer wall of the panel 100 is in contact with the side wall of the fastener 7. The end of the rib 200 extends to the outside of the panel 100 and is fastened to the fastener groove 8.

[0053] The upper end of the drive member 13 is detachably connected to the positioning strip 10. The bottom of the drive member 13 extends below the positioning strip 10 and is provided with a roller that cooperates with the drive groove 14. When the roller rolls on the guide surface as the drive member 13 descends, the positioning strip 10 moves away from the rib 200 as the roller rolls.

[0054] The base plate 3 is detachably connected to the four sides with baffles 23 for horizontally limiting the composite board, and the bottom ends of the pressure plate 5 are detachably connected to baffles 23 for longitudinally limiting the panel.

[0055] When using the installation device, the operator first installs the composite board 300 on the base plate 3 and limits its position using the retaining edge 23. Then, the panel 100 and the rib 200 are installed sequentially on the pressure plate 5, and the panel 100 is limited by the cooperation of the fastening strip 7 and the retaining edge 23. At the same time, the rib 200 is limited by the fastening groove 8. After the panel 100 and the rib 200 are installed, the positioning strip 10 moves towards the rib 200 under the action of the second elastic element 12, and the rib 200 is compressed by the extrusion plate 9. Thus, the rib 200 is kept relatively fixed with the pressure plate 5 under the compression action, and the height of the panel 100 is limited accordingly.

[0056] After the panel 100 and rib 200 are installed in place, the operator places the pressure plate 5 on the guide rod 4 and uses the elastic force of the first elastic element 6 to separate the rib 200 and the composite plate 300, thus achieving the initial state of the hot pressing fixture. After the pressure plate 5 is placed, the hot pressing fixture is transported to the bottom of the hot pressing mechanism 2 by the conveyor roller 1. Then, the hot pressing mechanism 2 applies downward pressure to the pressure plate 5, causing the pressure plate 5 to move the panel 100 and rib 200 downward under pressure. When the rib 200 moves to the initial engagement state with the transverse groove 400, the roller at the lower end of the drive member 13 moves to be in contact with the guide surface of the drive groove 14. At this time, the subsequent descent action of the drive member 13 will drive the positioning strip 10 to move away from the rib 200, thereby separating the extrusion plate 9 and the rib 200, thus releasing the height limit on the rib 200 and the panel 100.

[0057] As the positioning strip 10 opens outward, the lower end of the pin 16 extends into the groove 22. The positioning strip 10 on one side of the groove 22 applies an outward pressing force to the third stop 21, causing the pin 16 to rotate under this pressing force. The second stop 18 moves towards the through hole 20 as it rotates. When the second stop 18 rotates to be completely aligned with the through hole 20 in the horizontal direction, the lower end of the pin 16 moves to the other side of the positioning strip 10, and the pin holder 15 releases its height restriction on the second stop 18. Under the rebound action of the third elastic member 19, the pin 16 moves downward, causing the lower end of the pin 16 to move below the groove 22, thus forming a one-way restriction on the positioning strip 10.

[0058] When the pressure plate 5 is pressed down to fit against the guide sleeve on the base plate 3, the hot pressing mechanism 2 is in a fully pressed state and maintains the hot pressing and forming of the E plate, so that the panel 100, rib 200 and composite plate 300 are glued and fixed together under the action of hot pressing.

[0059] After hot pressing is completed, the hot pressing mechanism 2 rises and resets, while the pressure plate 5 moves upward under the rebound action of the first elastic element 6. As the pressure plate 5 rises, the roller at the bottom of the drive element 13 disengages from the drive groove 14, thereby releasing the horizontal limit on the positioning strip 10. This allows the positioning strip 10 to move towards the rib 200 under the rebound action of the second elastic element 12. At this time, the pin 16, which is in a low position, can limit the positioning strip 10, keeping it in its open state and preventing the extrusion piece 9 from re-attaching to the rib 200 and causing extrusion. This allows the pressure plate 5 to rise normally and separate from the E plate.

[0060] After the hot pressing mechanism 2 is reset, it is sent out by the conveyor roller 1. Then, the operator removes the pressure plate 5 and takes out plate E for subsequent processing. When it is necessary to install the subsequent ribs 200, the operator only needs to pull out the pin 16 and rotate it so that the first stop 17 re-fits the pin holder 15, which will allow the second stop 18 to return to its initial misalignment with the perforation 20, thus completing the quick reset of the spring pin.
