Description

Technical Field

[0001] The present invention belongs to the technical field of decorative panel production, and in particular relates to an embossing device and an embossing method for producing decorative panels. Background Art

[0002] Decorative panels, commonly known as panels, are made by precisely planing solid wood into thin veneers approximately 0.2mm thick, using plywood as a base material and gluing them together to create a single-sided decorative panel. Decorative panels are made from wood panels, which are essentially boards made from whole wood. These panels are durable and have a natural grain, making them an excellent choice for interior decoration. However, these panels are expensive, so embossing machines are used to imprint three-dimensional patterns on ordinary wood panels.

[0003] The embossing of decorative panels is mostly completed by an embossing device. In the existing technology, a pair of embossing rollers are mostly used to emboss the panels. During the embossing process, the surface of the wooden board is squeezed into a certain texture by the pattern on the embossing roller. In this process, wood chips generated by deformation of the wooden board will adhere to the texture of the embossing roller. Over time, if the time is too long, too much wood chips will accumulate in the texture of the embossing roller, which will affect the embossing effect. Summary of the Invention

[0004] The purpose of the present invention is to address the above-mentioned technical problems and provide an embossing device and an embossing method for producing decorative panels, thereby achieving the effect of ensuring the embossing quality.

[0005] In view of this, the present invention provides an embossing device for producing decorative panels, comprising a base, on which is provided:

[0006] There are two embossing rollers, which can rotate synchronously in the circumferential direction. The two embossing rollers are parallel to each other and a plate gap is formed between them.

[0007] A chip cleaning component is used to remove wood chips in the pattern of the embossing roller.

[0008] In this technical solution, by providing a chip cleaning component, wood chips in the embossing roller pattern can be removed, preventing excessive accumulation of wood chips that affects the embossing effect and ensuring the embossing quality.

[0009] Furthermore, the chip cleaning assembly includes two chip cleaning brushes, which are fixed on the base. The two chip cleaning brushes correspond to the two embossing rollers respectively and are tightly attached to the side of the embossing roller away from the plate gap.

[0010] Furthermore, the chip cleaning assembly also includes a built-in chip cleaning device placed inside the embossing roller, and the built-in chip cleaning device can remove wood chips in the pattern of the embossing roller through impact force.

[0011] In this technical solution, by setting up an external chip cleaning brush and an internal built-in chip cleaning device, the wood chips can be first knocked loose and then cleaned. The internal vibration and external sweeping are used to ensure that the wood chips accumulated in the embossing roller pattern are cleaned up in a two-pronged manner.

[0012] Furthermore, the built-in chip cleaning device includes:

[0013] An internal frame, wherein the internal frame is coaxially arranged inside the embossing roller with the embossing roller;

[0014] A rotating shaft, the rotating shaft and the embossing roller coaxially pass through the built-in frame and are circumferentially fixedly connected to the built-in frame and axially slidably connected, one end of the rotating shaft extending out of the embossing roller and connected to a driving source, the driving source being used to drive the rotating shaft to move along its own axial direction;

[0015] Impact plates, wherein a plurality of impact plates are arranged around the circumference of the rotating shaft, an elastic layer is provided on the outside of the impact plates, and both ends of the impact plates are slidably arranged on the built-in frame, and the sliding direction of the impact plates is on the extension line of the diameter of the rotating shaft;

[0016] A rotating rod, one end of which is rotatably connected to the outer wall of the rotating shaft, and the other end of which is rotatably connected to the impact plate.

[0017] In this technical solution, the driving source is started to move the rotating shaft along its own axial direction, and multiple impact plates can be driven to slide through the rotating rod, and at the same time approach or move away from the rotating shaft. When the impact plate gradually moves away from the rotating shaft until it hits the inner wall of the embossing roller, the impact force will impact the embossing roller and cause the wood chips accumulated in the pattern of the embossing roller to fall off or loosen. The loosened wood chips can fall off through the hanging brush of the chip cleaning brush, thereby achieving the purpose of cleaning the embossing roller.

[0018] Furthermore, the built-in chip cleaning device also includes a positioning structure, which is used to adjust the position of the impact plate by circumferential rotation.

[0019] Furthermore, the positioning structure includes:

[0020] A reference sleeve is coaxially fixedly arranged on the inner wall of the mounting hole at one end of the embossing roller, and the rotating shaft passes through the reference sleeve and is slidably connected to the reference sleeve. The reference sleeve is provided with a plurality of first guide pieces at intervals along the circumferential direction, and a limiting groove is formed between two adjacent first guide pieces. The ends of the first guide pieces are each provided with a first guide inclined surface;

[0021] The driving sleeve has a limiting protrusion on its outer periphery that matches the limiting groove. The limiting protrusion is clamped in the limiting groove so that the driving sleeve is slidably arranged in the reference sleeve. The rotating shaft passes through the driving sleeve and is axially fixedly connected to the driving sleeve and is circumferentially rotatably connected to the driving sleeve. The end of the driving sleeve away from the reference sleeve is provided with saw teeth.

[0022] A steering sleeve, wherein the steering sleeve sliding sleeve is provided on the rotating shaft and is fixedly connected to the rotating shaft in the circumferential direction. The steering sleeve and the driving sleeve can rotate relative to each other. The outer ring of the steering sleeve is fixedly connected to the above-mentioned inner frame in the circumferential direction and is axially slidably connected. Second guide pieces are arranged at intervals on the outer circumference of the steering sleeve. The ends of the second guide pieces are each provided with a second guide inclined surface. The width of the second guide piece matches the limiting groove, and the second guide inclined surface matches the first guide inclined surface.

[0023] Among them, the serrations of the driving sleeve have a third guide slope that matches the second guide slope, and an adjustment spring is provided in the axial direction between the steering sleeve and the built-in frame, and the adjustment spring always has a movement tendency to push the steering sleeve to move along the axis toward the reference sleeve.

[0024] In the present technical solution, when the driving source is started to move the rotating shaft along its own axial direction so that the impact plate hits the inner wall of the embossing roller to achieve the cleaning purpose, the driving sleeve moves with the rotating shaft, pushing the steering sleeve to move in the direction away from the reference sleeve. When the impact plate hits the inner wall of the embossing roller, the second guide piece disengages from the limiting groove. At this time, the steering sleeve has no limitation on the circumferential direction of the limiting groove. Therefore, under the spring force of the adjusting spring, the steering sleeve moves along the first guide bevel and the second guide bevel to the third guide bevel. The steering sleeve rotates to drive the rotating shaft and the built-in chip cleaning device to rotate, thereby achieving the impact plate. The driving source adjusts the position of the rotating shaft to reset and slide, the impact plate gradually moves closer, and the driving sleeve also resets and slides, and the steering sleeve continues to move along the first guide slope, so that the steering sleeve rotates with the rotating shaft and the built-in chip cleaning device, and the second guide piece of the steering sleeve is stuck in the next limit groove. Repeatedly starting the driving source can achieve a cycle state in which the impact plate hits the inner wall of the embossing roller, the built-in chip cleaning device rotates and adjusts the angle, and the impact plate hits the inner wall of the embossing roller, so as to realize that the impact plate hits all axial positions of the inner wall of the embossing roller, ensuring that the wood chips in each pattern of the circumference of the embossing roller are loosened by the impact force.

[0025] Furthermore, the driving source is a cylinder, and the piston rod of the cylinder is in the same straight line as the rotating shaft.

[0026] In this technical solution, the piston rod of the cylinder can be connected to the rotating shaft in a circumferential rotation and fixedly connected axially; the piston rod of the cylinder can also be not connected to the rotating shaft. The cylinder piston rod extends to push the rotating shaft to move, and the cylinder piston rod retracts without driving the rotating shaft to move back. A return spring is provided at the other end of the rotating shaft away from the cylinder, and the elastic force of the return spring causes the rotating shaft to move back.

[0027] Furthermore, the embossing device is also provided with an adjusting structure, which is used to adjust the size of the paper feeding gap between the two embossing rollers.

[0028] Furthermore, the adjustment structure includes an adjusting screw, which is threadedly connected to the base, the embossing roller is slidingly connected to the base through a slider, and the end of the adjusting screw is circumferentially rotationally connected to the slider and axially fixedly connected.

[0029] Furthermore, the embossing method of the embossing device comprises the following steps:

[0030] S1: embossing: placing the decorative panel into the gap between the panels, and allowing the embossing roller to emboss the surface of the decorative panel;

[0031] S2: Impact chip cleaning, the built-in chip cleaning device impacts the inner wall of the embossing roller, and uses the impact force to loosen or shake off the wood chips in the embossing roller pattern;

[0032] S3: Cleaning and clearing chips: Use the chip cleaning brush arranged on the outside of the embossing roller to brush away the wood chips loosened in the embossing roller pattern.

[0033] The beneficial effects of the present invention are:

[0034] 1. By setting up an external chip cleaning brush and an internal built-in chip cleaning device, the sawdust is first knocked loose and then cleaned. It can vibrate inside and sweep outside, and a two-pronged approach is used to ensure that the sawdust accumulated in the embossing roller pattern is cleaned up, preventing excessive accumulation of sawdust that affects the embossing effect and ensuring the embossing quality.

[0035] 2. The adjustment structure can adjust the impact plate's circumferential rotation to ensure that the wood chips in each pattern around the embossing roller are loosened by the impact force. BRIEF DESCRIPTION OF THE DRAWINGS

[0052] Example 1:

[0053] like Figure 1 The figure shows an embossing device for producing decorative panels. The device comprises a base 1, on which are mounted embossing rollers 2 and a chip cleaning assembly. The two embossing rollers 2 rotate synchronously and are parallel to each other, forming a plate-passing gap between them. The chip cleaning assembly is used to remove wood chips from the patterns on the embossing rollers 2. This removes wood chips from the patterns on the embossing rollers 2, preventing excessive accumulation that could affect the embossing effect and ensuring embossing quality.

[0054] Example 2:

[0055] like Figure 1As shown, the chip cleaning assembly includes two chip cleaning brushes 3, which are fixedly mounted on the base 1. The two chip cleaning brushes 3 correspond to the two embossing rollers 2, respectively, and are in close contact with the side of the embossing roller 2 away from the plate gap. The chip cleaning assembly also includes a built-in chip cleaning device placed inside the embossing roller 2. The built-in chip cleaning device can remove wood chips from the pattern of the embossing roller 2 through impact force. By providing an external chip cleaning brush 3 and an internal built-in chip cleaning device, the accumulated wood chips can be loosened before being cleaned. This two-pronged approach of internal vibration and external sweeping ensures that the wood chips accumulated in the pattern of the embossing roller 2 are completely removed.

[0056] Example 3:

[0057] like Figure 2-3 As shown, the built-in chip cleaning device includes a built-in frame 4, a rotating shaft 5, an impact plate 6 and a rotating rod 7. The built-in frame 4 is coaxially arranged inside the embossing roller 2; the rotating shaft 5 coaxially passes through the built-in frame 4 and is fixedly connected to the built-in frame 4 in the circumferential direction and slidably connected in the axial direction. One end of the rotating shaft 5 extends out of the embossing roller 2 and is connected to a driving source, which is used to drive the rotating shaft 5 to move along its own axial direction; multiple impact plates 6 are arranged around the circumferential direction of the rotating shaft 5, and an elastic layer 8 is arranged on the outside of the impact plates 6. The two ends of the impact plates 6 are slidably arranged on the built-in frame 4, and the sliding direction of the impact plates 6 is on the extension line of the diameter of the rotating shaft 5; one end of the rotating rod 7 is rotatably connected to the outer wall of the rotating shaft 5, and the other end is rotatably connected to the impact plate 6.

[0058] By starting the driving source to move the rotating shaft 5 along its own axial direction, the rotating rod 7 can drive multiple impact plates 6 to slide and approach or move away from the rotating shaft 5. When the impact plate 6 gradually moves away from the rotating shaft 5 until it hits the inner wall of the embossing roller 2, the impact force will impact the embossing roller 2 and cause the wood chips accumulated in the pattern of the embossing roller 2 to fall off or loosen. The loosened wood chips can fall off through the hanging brush of the chip cleaning brush 3, thereby achieving the purpose of cleaning the embossing roller 2.

[0059] Example 4:

[0060] like Figure 2 、 Figure 4-5As shown, the built-in chip cleaning device also includes a positioning structure, which is used to adjust the impact plate 6 in a circumferential rotation. The positioning structure includes a reference sleeve 9, a drive sleeve 10 and a steering sleeve 11. The reference sleeve 9 is coaxially fixed with the embossing roller 2 on the inner wall of the mounting hole 12 at one end of the embossing roller 2. The above-mentioned rotating shaft 5 passes through the reference sleeve 9 and is slidably connected to the reference sleeve 9. The reference sleeve 9 is provided with a plurality of first guide plates 13 spaced apart along the circumferential direction. A limiting groove 14 is formed between two adjacent first guide plates 13. The ends of the first guide plates 13 are both provided with a first guide slope 15; the outer periphery of the drive sleeve 10 is provided with a limiting protrusion 16 that matches the limiting groove 14. The limiting protrusion 16 is clamped in the limiting groove 14 so that the drive sleeve 10 is slidably set in the reference sleeve 9. The rotating shaft 5 passes through the drive sleeve 10 and is axially fixedly connected to the drive sleeve 10 and is circumferentially rotated. The end of the drive sleeve 10 away from the reference sleeve 9 is provided with a sawtooth 17; the steering sleeve 11 slides. The movable sleeve is mounted on the rotating shaft 5 and is circumferentially fixedly connected to the rotating shaft 5. The steering sleeve 11 and the driving sleeve 10 can rotate relative to each other. The outer ring of the steering sleeve 11 is circumferentially fixedly connected to the above-mentioned built-in frame 4 and is axially slidably connected. Second guide pieces 18 are arranged at intervals on the outer circumference of the steering sleeve 11. The ends of the second guide pieces 18 are each provided with a second guide bevel 19. The width of the second guide piece 18 matches the limiting groove 14, and the second guide bevel 19 matches the first guide bevel 15. The serrations 17 of the driving sleeve 10 have a third guide bevel 20 that matches the second guide bevel 19. An adjustment spring 21 is provided in the axial direction between the steering sleeve 11 and the built-in frame 4. The adjustment spring 21 always has a tendency to push the steering sleeve 11 along the axis toward the reference sleeve 9. The driving source is a cylinder, and the piston rod of the cylinder is aligned with the rotating shaft 5. The piston rod of the cylinder can be connected to the rotating shaft 5 in a circumferential rotation and fixedly connected in an axial direction; the piston rod of the cylinder can also be not connected to the rotating shaft 5. The cylinder piston rod extends to push the rotating shaft 5 to move, and the cylinder piston rod retracts without driving the rotating shaft 5 to move back. A return spring 22 is provided at the other end of the rotating shaft 5 away from the cylinder, and the elastic force of the return spring 22 causes the rotating shaft 5 to move back.

[0061] The initial state of the adjustment structure is as follows Figure 6 As shown, when the driving source is started to move the rotating shaft 5 along its own axial direction so that the impact plate 6 hits the inner wall of the embossing roller 2 to achieve the cleaning purpose, the driving sleeve 10 moves with the rotating shaft 5, pushing the steering sleeve 11 to move in the direction away from the reference sleeve 9. When the impact plate 6 hits the inner wall of the embossing roller 2, the second guide piece 18 comes out of the limiting groove 14, achieving the following Figure 7 At this time, the steering sleeve 11 is not limited by the infinite slot 14 in the circumferential direction. Therefore, under the spring force of the adjustment spring 21, the steering sleeve 11 moves along the first guide slope 15 and the second guide slope 19 to the third guide slope 20. Then the steering sleeve 11 rotates and drives the rotating shaft 5 and the built-in chip cleaning device to rotate, realizing the adjustment of the impact plate 6, achieving the following Figure 8The driving source causes the shaft 5 to slide back, the impact plate 6 gradually approaches, and the drive sleeve 10 also slides back, the steering sleeve 11 continues to move along the first guide slope 15 so that the steering sleeve 11 with the shaft 5 and the built-in chip cleaning device rotates the second guide piece 18 of the steering sleeve 11 into the next limit groove 14, to achieve the following Figure 9 Repeated activation of the driving source can achieve a cycle in which the impact plate 6 impacts the inner wall of the embossing roller 2, the built-in chip cleaning device rotates and adjusts its angle, and the impact plate 6 impacts the inner wall of the embossing roller 2. This allows the impact plate 6 to impact the inner wall of the embossing roller 2 at all axial positions, ensuring that wood chips in all patterns around the circumference of the embossing roller 2 are loosened by the impact force.

[0062] Example 5:

[0063] like Figure 1 As shown, the embossing device is also provided with an adjustment structure for adjusting the paper feeding gap between the two embossing rollers 2. The adjustment structure includes an adjustment screw 23, which is threadedly connected to the base 1. The embossing rollers 2 are slidably connected to the base 1 via a slider 24. The end of the adjustment screw 23 is connected to the slider 24 in a circumferential rotational connection and is fixedly connected in an axial direction.

[0064] The embossing method of the embossing device comprises the following steps:

[0065] S1: Embossing: Place the decorative panel into the gap between the panels and allow the embossing roller 2 to emboss the surface of the decorative panel;

[0066] S2: impact chip cleaning, the built-in chip cleaning device impacts the inner wall of the embossing roller 2, and uses the impact force to loosen or shake off the wood chips in the pattern of the embossing roller 2;

[0067] S3: Cleaning and clearing chips: The chip cleaning brush 3 arranged on the outside of the embossing roller 2 brushes away the loosened wood chips in the pattern of the embossing roller 2.

[0068] The embodiments of the present application are described above in conjunction with the accompanying drawings. Unless there is a conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive.
