Description

Technical Field

[0001] The invention relates to the technical field of UV excimer veneer paper processing, in particular to a method for processing UV excimer veneer paper. Background Art

[0002] UV excimer veneer paper is a special veneer paper treated with UV excimer light source. It is usually prepared by coating a special UV coating on the surface of the veneer paper and then curing and processing it with excimer ultraviolet light. The surface of the veneer paper treated in this way will have excellent wear resistance, water resistance and anti-fouling properties, while maintaining the natural texture and touch of the veneer paper. It is not only environmentally friendly, but also due to the high durability and aesthetics after surface treatment, it can meet the dual requirements of the high-end market for material quality and appearance. It is a material with high decorativeness and durability, and is widely used in furniture, flooring and other fields. Its processing process includes cutting edges, planing, sealing, sorting, printing, coating curing, quality inspection and other steps.

[0003] Among them, quality inspection is the most important step to ensure the production quality of UV excimer veneer paper, because UV excimer veneer paper is usually used on furniture boards. After long-term use, the surface of furniture boards will be stained with dust or oil, so they need to be wiped frequently. Wiping will cause friction to the UV excimer veneer paper on the furniture boards, so it is necessary to conduct surface wear resistance test on UV excimer veneer paper during quality inspection.

[0004] Existing veneer wear test methods usually use standardized wear equipment and wear materials to simulate the wear of veneer in actual use. Although these methods are effective in many cases, they also have some disadvantages and limitations, such as single test conditions: existing wear test methods are usually carried out under laboratory conditions, and the test parameters are fixed. However, the wear resistance of UV excimer veneer paper will change when it is exposed to environmental influences such as water vapor and oil pollution. The results of existing test methods may be different from the actual wear mode of long-term use, and cannot fully simulate the various complex situations in actual use. The single-condition test method cannot fully reflect the overall wear resistance of the material.

[0005] In addition, existing tests usually simulate long-term use by accelerating wear in a single direction. However, when wiping the surface of UV excimer veneer paper in actual use, the veneer surface may be subjected to friction in different directions, so it cannot accurately reflect the wear resistance of the veneer in actual use. Summary of the invention

[0006] The invention provides a processing method for UV excimer veneer paper, which solves the technical problem that the existing veneer wear resistance test method mainly uses standardized equipment and materials under laboratory conditions, the test parameters are fixed, and the performance changes caused by the diversified environment (such as water vapor and oil pollution) of UV excimer veneer paper in actual use cannot be simulated. The test conditions are single and it is difficult to fully reflect the overall wear resistance of the material. In addition, these tests usually use unidirectional wear and cannot accurately simulate the multi-directional friction that the veneer may suffer in actual use, resulting in the test results being inconsistent with the actual use performance.

[0007] The present invention provides a method for processing UV excimer veneer paper, and the specific steps of the method for processing UV excimer veneer paper are as follows:

[0008] S1. Cutting edges: Use a cutting machine to cut the veneer raw material into the required size and remove the excess edges.

[0009] S2. Planing: Place the veneer after trimming into a planer for planing and leveling, and adjust the thickness of the veneer to the uniform thickness required by the design.

[0010] S3. Sealing: Sealing the edges of the sliced ​​veneer to prevent moisture intrusion.

[0011] S4. Sorting: Classify the veneer according to its color, texture and size characteristics, and select the veneer of qualified quality for subsequent processing.

[0012] S5. Printing: Design the surface pattern of the veneer according to customer needs, use a UV printer to print the pattern on the veneer, and use UV light curing technology to quickly cure the coating.

In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0039] See also Figure 1 and Figure 2 The present invention provides a technical solution: a method for processing UV excimer veneer paper. The specific steps of the method for processing UV excimer veneer paper are as follows:

[0040] S1. Cutting edges: Use a cutting machine to cut the veneer raw material into the required size and remove the excess edges.

[0041] S2. Planing: Place the veneer after trimming into a planer for planing and leveling, and adjust the thickness of the veneer to the uniform thickness required by the design.

[0042] S3. Sealing: Sealing the edges of the sliced ​​veneer to prevent moisture intrusion.

[0043] S4. Sorting: Classify the veneer according to its color, texture and size characteristics, and select the veneer of qualified quality for subsequent processing.

[0044] S5. Printing: Design the surface pattern of the veneer according to customer needs, use a UV printer to print the pattern on the veneer, and use UV light curing technology to quickly cure the coating.

[0045] S6. Coating and curing: Coat the surface of the veneer with UV excimer coating, and cure the coating through UV light to improve the wear resistance and weather resistance of the veneer.

[0046] S7. Quality inspection: The coated and cured veneer is subjected to a wear resistance test by means of a simulated multi-directional testing mechanism 3 to ensure that the quality of the veneer meets the standards.

[0047] The UV excimer veneer paper processing method steps in the above steps S1-S7 need to be completed by the support platform 1, the clamping mechanism 2 and the simulation multi-directional testing mechanism 3.

[0048] A clamping mechanism 2 for clamping the UV excimer veneer paper and automatically stretching and flattening it is installed on the upper end surface of the supporting platform 1, and a simulation multi-directional testing mechanism 3 for rubbing the UV excimer veneer paper under different friction conditions and in multiple directions is installed on the upper part of the supporting platform 1.

[0049] See also Figure 2 , Figure 7 and Figure 8 In this embodiment, the clamping mechanism 2 includes a strip plate 21 slidably connected to the upper end surface of the carrying platform 1 through a spring telescopic column. The strip plate 21 is symmetrically hinged to two hinged rod groups 22 on the opposite side of the carrying platform 1. The upper end surface of the carrying platform 1 is symmetrically fixedly connected to two plate bodies 23. The plate bodies 23 are provided with guide grooves 24. The guide grooves 24 are in an inclined state of being higher on the side close to the strip plate 21 and lower on the side away from the strip plate 21. A sliding column 25 is slidably connected in the guide groove 24. The middle parts of the two hinged rod groups 22 are respectively hinged with sliding sleeves arranged on the sliding The vertical frame 26 outside the column 25 and the front end of the sliding column 25 are fixedly connected with a clamping plate 27, the upper end surface of the supporting platform 1 and directly below the clamping plate 27 are fixedly connected with a placement seat 28, the lower end surface of the clamping plate 27 is fixedly connected with an elastic rubber pad, and the lower end surface of the elastic rubber pad is fixedly connected with a plurality of elastic protrusions equidistantly. The elastic rubber pad is used to protect the UV excimer veneer paper when the clamping plate 27 clamps the UV excimer veneer paper, and the elastic protrusions are used to increase the friction between the elastic rubber pad and the UV excimer veneer paper, thereby enhancing the reliability of the UV excimer veneer paper when it is clamped.

[0050] First, the strip plate 21 is pulled upward to move upward, driving the hinge rod group 22 to rotate, and the hinge rod group 22 then drives the two vertical frames 26 to move closer to each other, and the vertical frames 26 then drive the two sliding columns 25 to move closer to each other, so that the sliding columns 25 move along the path of the guide groove 24. Since the guide groove 24 is in an inclined state where the side close to the strip plate 21 is higher and the side away from the strip plate 21 is lower, the two sliding columns 25 will gradually lift upward under the action of the guide groove 24 during the process of moving closer to each other. The sliding column 25 then drives the clamping plate 27 to move upward, so that the clamping plate 27 is separated from the upper surface of the placement seat 28, and then the UV excimer veneer paper is laid flat on the placement seat 28, and the pulled strip plate 21 is released, and the spring telescopic column is reset and retracted. The contraction drives the strip plate 21 to move downward, and the strip plate 21 moves downward and presses the hinged rod group 22 to rotate around its own middle part, and the hinged rod group 22 then pushes the vertical frame 26 to move away from the strip plate 21, and the vertical frame 26 drives the sliding column 25 to move, and the sliding column 25 then gradually moves toward the lower part of the guide groove 24, and then drives the clamping plate 27 to gradually move downward, so that the clamping plate 27 contacts the surface of the UV excimer veneer paper on the placement seat 28, and the clamping plate 27 contacts downward and moves to both sides at the same time, so that the UV excimer veneer paper can be pressed down and clamped while pulling it to the left and right sides to make it flat, thereby ensuring that the UV excimer veneer paper can be laid flat on the placement seat 28 for subsequent friction testing.

[0051] See also Figure 2 and Figure 3 In this embodiment, the simulation multi-directional testing mechanism 3 includes an L-shaped frame 31 fixedly connected to the upper end surface of the bearing platform 1, a load-bearing spring telescopic rod 32 fixedly connected to the lower end surface of the transverse section of the L-shaped frame 31, a mounting rod 33 fixedly connected to the lower end of the load-bearing spring telescopic rod 32, an annular frame 34 fixedly connected to the outside of the mounting rod 33, a plurality of load-bearing rings 35 fixedly connected to the circumferential outer wall of the annular frame 34 at equal intervals through fixed blocks, a sliding rod 310 slidably connected to the load-bearing ring 35, a return spring 311 fixedly connected between the sliding rod 310 and the load-bearing ring 35, and an expansion and displacement assembly 36 arranged on the outside of the sliding rod 310, each expansion and displacement assembly 36 having a lower Two friction components 37 for rubbing the surface of UV excimer veneer paper are installed in each part, and the expansion component 36 is used to drive the two friction components 37 to move toward each other. The front end surface of the vertical section of the L-shaped frame 31 is rotatably connected to the driving shaft 313 through the support plate 312. A pushing component 38 is commonly provided between the driving shaft 313 and the mounting rod 33 for pushing the sliding rod 310 downward in turn so as to select the friction components 37 at different positions to contact with the UV excimer veneer paper. A driving component 39 is commonly provided between the driving shaft 313 and the mounting rod 33 for driving the mounting rod 33 to move downward as a whole so that the friction component 37 contacts with the surface of the UV excimer veneer paper for friction.

[0052] See also Figure 3 , Figure 4 and Figure 5 The top moving assembly 38 includes two C-shaped frames 381 symmetrically fixedly connected to the outside of the mounting rod 33 by a fixing rod and a swivel 382 rotatably connected to the two C-shaped frames 381, the lower part of the swivel 382 is fixedly connected to an arc-shaped top pressure block 383, the outer wall of the sliding rod 310 is fixedly connected to a pressure column 384 perpendicular to the mounting rod 33 and cooperating with the arc-shaped top pressure block 383, the outer part of the swivel 382 is fixedly connected to a gear ring 385, the outer part of the driving shaft 313 is fixedly connected to an incomplete gear disk 386 cooperating with the gear ring 385, and the lower part of the arc-shaped top pressure block 383 is provided with an arc-shaped groove, which is used to cooperate with the pressure column 384 so that the arc-shaped top pressure block 383 can be firmly in contact with the outside of the pressure column 384.

[0053] See also Figure 5 and Figure 6 The drive assembly 39 includes a transverse plate 391 fixedly connected to the outside of the mounting rod 33 and a column shaft 392 fixedly connected to the lower end surface of the transverse plate 391. The front end surface of the vertical section of the L-shaped frame 31 is fixedly connected to a ring 393 through a pillar. A ring 394 slidably sleeved on the outside of the column shaft 392 is rotatably connected inside the ring 393. A spiral groove 395 is provided on the outer wall of the column shaft 392. A sliding column 396 slidably set in the spiral groove 395 is fixedly connected to the upper part of the ring 394 through a protrusion. A gear ring 397 is fixedly connected to the outside of the ring 394. A second incomplete toothed disc 398 cooperating with the gear ring 397 is fixedly connected to the outside of the drive shaft 313. The toothless position of the second incomplete toothed disc 398 is staggered with the toothless position of the first incomplete toothed disc 386.

[0054] When the UV excimer veneer paper is subjected to friction test, the self-driven driving shaft 313 is first controlled to rotate, and the driving shaft 313 then drives the No. 1 incomplete toothed disc 386 to rotate. When the teeth on the No. 1 incomplete toothed disc 386 mesh with the gear ring 385, the rotating ring 382 is driven to rotate, and the rotating ring 382 then drives the arc-shaped top pressure block 383 to rotate. When the arc-shaped top pressure block 383 rotates to conflict with the pressure column 384, the inclined surface of the arc-shaped top pressure block 383 squeezes the pressure column 384 to make it move downward. The pressure column 384 then drives the slide bar 310 to move downward, and the slide bar 310 then drives the friction assembly 37 to move downward through the expansion assembly 36 until the protrusion of the arc-shaped top pressure block 383 abuts against the outside of the pressure column 384. At this time, the arc-shaped groove abuts against the outside of the pressure column 384, and the slide bar 310 is pushed down to the lowest position. The toothless part of the No. 1 incomplete toothed disc 386 rotates to the toothed part that meshes with the toothed ring 385, that is, at this time, the No. 1 incomplete toothed disc 386 is separated from the toothed ring 385.

[0055] The driving shaft 313 then continues to rotate, driving the teeth of the second incomplete gear disc 398 to mesh with the gear ring 397 (when the first incomplete gear is in meshing with the gear ring 385, the second incomplete gear disc 398 and the gear ring 397 are not in meshing state), the gear ring 397 then drives the ring 394 to rotate, and the ring 394 then drives the sliding column 396 to rotate through the protrusion. During the rotation of the sliding column 396, the spiral groove 395 is squeezed to make the column shaft 392 move downward, and the column shaft 392 then drives the installation rod 33 to move downward, and the installation rod 33 then drives the load-bearing spring telescopic rod 32 to be stretched, and the installation rod 33 then drives the expansion assembly 36 and the friction assembly 37 to move downward through the annular frame 34, so that the friction assembly 37 contacts the surface of the UV excimer veneer paper to rub the surface of the UV excimer veneer paper.

[0056] After the test of UV excimer veneer paper is completed, the second incomplete toothed disc 398 rotates until its teeth are separated from the gear ring 397, and then the spring-loaded telescopic rod 32 is reset and contracted to pull the mounting rod 33 upward, and the mounting rod 33 then drives the friction assembly 37 upward through the annular frame 34 to move the UV excimer veneer paper away. When the mounting rod 33 moves upward, it also drives the column shaft 392 upward through the cross plate 391. During the upward movement of the column shaft 392, the position of the spiral groove 395 is continuously changed to adjust the sliding column 396. The extrusion causes the ring 394 to rotate in the opposite direction until the mounting rod 33 moves up and resets to the initial position. At this time, the No. 1 incomplete toothed disc 386 rotates again to engage with the toothed ring 385. The No. 1 incomplete toothed disc 386 drives the rotating ring 382 to rotate again through the toothed ring 385. The rotating ring 382 then drives the arc-shaped pressing block 383 to rotate and move away from the position of the sliding rod 310 that is pressed downward. The compressed restoring spring 311 resets and expands to push the sliding rod 310 upward until the sliding rod 310 moves up to the initial position.

[0057] When the rotating ring 382 drives the arc-shaped pressing block 383 to rotate to the position of the next slide bar 310, the operation of pressing the previous slide bar 310 downward is repeated, so that the friction component 37 located at another position can be controlled to contact the surface of the UV excimer veneer paper, and the UV excimer veneer paper can be friction tested from another angle. The arc-shaped pressing block 383 successively contacts the pressure columns 384 at different positions during the circumferential rotation, thereby pushing the friction components 37 at different positions to test the UV excimer veneer paper, which can simulate the friction of the UV excimer veneer paper from different directions during actual use.

[0058] See also Figure 3 and Figure 4In this embodiment, the expansion and movement assembly 36 includes a first Y-shaped frame 361 hinged on the outside of the slide bar 310, a connecting block 362 fixedly connected to the outside of the slide bar 310 on the side away from the annular frame 34, and a second Y-shaped frame 363 hinged on the outside of the connecting block 362 and slidably sleeved on the outside of the first Y-shaped frame 361. The lower end of the slide bar 310 is fixedly connected to a connecting plate 364. The first Y-shaped frame 361 and the side opposite to the connecting plate 364 and the second Y-shaped frame 363 and the side opposite to the connecting plate 364 are respectively The friction assembly 37 includes a rotating column 371 fixedly connected to the No. 1 Y-shaped frame 361 and the No. 2 Y-shaped frame 363, a rectangular frame 372 hinged on the rotating column 371 through a lug, a torsion spring is fixedly connected between the lug and the rotating column 371, a friction block 373 is fixedly connected to the lower end surface of the rectangular frame 372, a plurality of fine holes 374 are equidistantly provided on the friction block 373, and a wiping strip 375 is symmetrically fixedly connected to the lower end surface of the friction block 373.

[0059] Before conducting a friction test, first prepare two sponge blocks and soak them with water and oil respectively. Then, place the soaked sponge blocks into a rectangular frame 372 arranged in an inverted circumferential direction so that the sponge blocks are in contact with the upper surface of the friction block 373. Then, the water in the water-storing sponge block flows into the fine hole 374 under gravity, and the oil in the oil-storing sponge block flows into the fine hole 374 located in the other friction block 373 under gravity. When the slide rod 310 is pushed down by the arc-shaped top pressure block 383 and the pressure column 384, the expansion assembly 36 and the friction assembly 37 are driven to move downward as a whole.

[0060] During the downward movement of the friction assembly 37 pushed by the driving assembly 39, the friction block 373 away from the annular frame 34 will first contact the surface of the UV excimer veneer paper, and then the No. 1 Y-shaped frame 361 will be pushed and rotated to drive the friction block 373 away from the annular frame 34 to move along the radial direction of the annular frame 34 in the direction away from the annular frame 34, and then the friction block 373 close to the annular frame 34 will contact the UV excimer veneer paper, and the No. 2 Y-shaped frame 363 will be pressed to rotate around the connecting plate 364 under the downward movement of the annular frame 34, so that the friction block 373 close to the annular frame 34 is pushed to move close to the annular frame 34 to prevent the UV from being contaminated. The surface of the excimer veneer paper is rubbed, and a sponge block for storing water, a sponge block for storing oil, and nothing are placed on the upper part of the circumferentially arranged friction blocks 373 in sequence, and then the circumferentially arranged friction blocks 373 are controlled to contact with the UV excimer veneer paper in sequence, so that the surface of the UV excimer veneer paper can be tested for wet friction in a humid state, friction in an oily state, and normal dry friction in sequence. Testing the UV excimer veneer paper under different environmental parameters can more truly reflect the wear resistance of the UV excimer veneer paper in daily use, thereby more comprehensively testing the wear resistance of the UV excimer veneer paper in different usage environments.

[0061] The movement of the friction block 373 drives the wiping strip 375 to move synchronously, so that the water or oil flowing on the surface of the UV excimer veneer paper during the friction process can be automatically wiped off.
