Description

Technical Field

[0001] The invention relates to the technical field of wear resistance detection, in particular to a wear resistance detection device for plywood impregnated decorative paper. Background Art

[0002] Plywood impregnated decorative paper usually refers to a decorative material that is made by impregnating special paper with resin through a specific process and then hot-pressing it on the surface of plywood. This material is widely used in the market, especially in furniture manufacturing and interior decoration. However, the quality of impregnated film paper veneer panels on the market varies greatly, and unqualified items are mainly concentrated in surface properties, such as wear resistance, water vapor resistance, pollution resistance, etc. The quality of these properties mainly depends on the degree of curing of the impregnated film paper and the bonding strength between the decorative paper and the panel.

[0003] Therefore, the surface performance of the plywood impregnated decorative paper needs to be tested before it is produced and put into use. Among them, the wear resistance of the plywood impregnated decorative paper is particularly important. If the wear resistance of the plywood is poor, it will not only affect the appearance, but also shorten the overall service life of the product.

[0004] The existing wear resistance test of plywood usually involves fixing several plywood sheets in corresponding wear resistance test equipment, and then rubbing the surface of the plywood sheets back and forth through the test equipment. This test method has certain disadvantages. Since plywood sheets are subjected to friction forces of different angles, heights and pressures during actual use, when the plywood sheets are placed in the test equipment for wear resistance test, it is impossible to simulate the scene of the plywood sheets during actual use, resulting in inaccurate test results. At the same time, wear resistance test of plywood sheets in only one direction is often not representative. Summary of the invention

Detailed implementation manners

[0030] The following will Figure 1-10 further elaborate on this application.

[0031] Please refer to Figure 1 for reference. A wear resistance detection device for plywood impregnated decorative paper includes two inverted T-shaped platforms 1 that are symmetrically arranged left and right. Between the horizontal sections of the two inverted T-shaped platforms 1, there is a supporting plate 2 for supporting the plywood to be tested. Below the supporting plate 2, there is a limiting mechanism 3 for limiting the plywood to be tested. Between the vertical sections of the two inverted T-shaped platforms 1, there is a common mounting plate 4. On the mounting plate 4, there is a detection mechanism 5 for performing wear resistance detection on the plywood to be tested.

[0032] During specific operation, first, several plywood to be tested are manually placed on the supporting plate 2, and then the limiting mechanism 3 is started to limit the several plywood to be tested to ensure that their positions do not shift during the wear resistance test. Then, the detection mechanism 5 is controlled to synchronously detect the several plywood to be tested. After one detection is completed, the supporting plate 2 is controlled to drive the several plywood to be tested to move to a specified position, and then the detection mechanism 5 performs a secondary detection on the several plywood to be tested. Finally, after the detection work on both sides is completed, the plywood to be tested is taken out and its surface is observed to see if it meets the requirements of the wear resistance test.

[0033] Please refer to Figure 1 and Figure 3 for reference. The horizontal sections of the two inverted T-shaped platforms 1 are each provided with a rectangular through groove 11 along the left-right direction. The side walls of the vertical sections of the two inverted T-shaped platforms 1 that are close to each other are each provided with a slide rail extending in the up-down direction. The slide rail provided on the left inverted T-shaped platform 1 is an electric slide rail.

[0034] Please refer to Figure 2 and Figure 4 , the left and right ends of the supporting plate 2 are respectively fixedly arranged in the rectangular through grooves 11 of the two inverted T-shaped platforms 1. The left side wall of the supporting plate 2 is set as an inclined section, that is, the height of the inclined section gradually increases from left to right. The lower end surface of the supporting plate 2 is symmetrically provided with T-shaped sliding grooves one 21 distributed in the front-back direction on the left and right. The center position of the upper end surface of the supporting plate 2 is provided with a T-shaped sliding groove two 22 in the left-right direction. A reverse T-shaped slider is slidably arranged in the T-shaped sliding groove two 22. The upper end surface of the reverse T-shaped slider is fixedly provided with an L-shaped supporting plate 23 for placing the plywood to be measured. The vertical section of the L-shaped supporting plate 23 is located on the side away from the inclined section. A displacement component 24 for driving the plywood to be measured to move is further arranged in the T-shaped sliding groove two 22.

[0035] Please refer to Figure 5 , two groups of strip-shaped grooves 231 are symmetrically arranged in the front-back direction on the upper end surface of the horizontal section of the L-shaped supporting plate 23. The two groups of strip-shaped grooves 231 include two strip-shaped grooves 231, and a rectangular push plate 232 is slidably arranged in each strip-shaped groove 231. The rectangular push plates 232 are respectively fixedly connected with the side walls of the corresponding strip-shaped grooves 231 through a plurality of springs.

[0036] Please refer to Figure 4 , the limiting mechanism 3 includes racks one 31 that are symmetrically slidably arranged in the two T-shaped sliding grooves one 21 on the left and right. The far ends of the two racks one 31 are fixedly provided with connecting plates. The side walls of the two connecting plates close to each other are both fixedly provided with U-shaped limiting frames 32 with opposite openings. The limiting mechanism 3 further includes a transmission gear 33 rotatably arranged on the lower end surface of the supporting plate 2. The transmission gear 33 is driven by an external motor and meshes with the two racks one 31 respectively for transmission.

[0037] During specific operation, first, several plywood to be measured are manually pushed from the inclined section of the supporting plate 2 onto the L-shaped supporting plate 2, and the right end of the plywood to be measured is made to closely adhere to the vertical section of the L-shaped supporting plate 2. Then, the external motor is started to drive the transmission gear 33 to rotate. When the transmission gear 33 rotates, it meshes with the two racks one 31 respectively and drives the two racks one 31 and the two U-shaped limiting frames 32 to approach each other. At this time, the adjacent plywood to be measured on the L-shaped supporting plate 2 are gradually fitted under the push of the rectangular push plates 232, and thus the limiting and fixing work of several plywood to be measured is completed.

[0038] It should be noted that the height of the plywood to be measured is higher than the height of the rectangular push plates 232 on the L-shaped supporting plate 2.

[0039] Please refer to Figure 3The left and right ends of the mounting plate 4 are respectively provided with an electric slider 41 and a sliding block 42. The side of the mounting plate 4 on which the electric slider 41 is provided is slidably provided inside the electric slide rail, and the side of the mounting plate 4 on which the sliding block 42 is provided is slidably provided in the slide rail on the other side of the inverted T-shaped stage 1. The upper end of the mounting plate 4 is close to the electric slider 41 and is provided with three sliding grooves 43 extending in the left and right directions along the front-to-back direction. The lower end surface of the mounting plate 4 is also provided with three mounting grooves 44 at positions corresponding to the three sliding grooves 43. The side of the mounting plate 4 close to the sliding block 42 is provided with a circular through groove 45 downwardly.

[0040] Please refer to Figure 2 The displacement assembly 24 includes a reciprocating motor 241 fixedly arranged inside the right rectangular through slot 11, and a threaded rod 242 is fixedly arranged on the outer wall of the output shaft of the reciprocating motor 241. The threaded rod 242 is arranged along the left and right directions, and the left end of the threaded rod 242 is threadedly connected to the inverted T-shaped slider.

[0041] Please refer to Figure 6 and Figure 8 The detection mechanism 5 includes a detection component 51 arranged at the left end of the mounting plate 4, the detection component 51 includes a linkage gear 511, three linkage gears 511 are provided and are rotatably arranged in three mounting grooves 44 respectively, and a detection block 512 is fixedly arranged on the lower end surface of the three linkage gears 511, the lower end surface of the detection block 512 is arc-shaped, and a plurality of detection rollers 513 are rotatably arranged on the arc-shaped outer wall along the circumferential direction, a rack 2 514 is meshedly arranged above the linkage gear 511, the rack 2 514 is slidably arranged in the sliding groove 43, and an E-type connecting plate 515 is fixedly arranged on the upper end surfaces of the three racks 2 514, and a telescopic push rod 516 is fixedly connected to the right side wall of the E-type connecting plate 515, and the telescopic push rod 516 is fixedly arranged on the upper end surface of the mounting plate 4 through a supporting seat, and the detection mechanism 5 also includes a detection component 2 52 arranged on the right end of the mounting plate 4.

[0042] When several plywood boards to be tested have completed the limiting work, the electric slider 41 is controlled to drive the mounting plate 4 to move downward until the outer wall of the detection roller 1 513 is in contact with the upper surface of the corresponding plywood board to be tested, and then the reciprocating motor 241 is started to drive the threaded rod 242 to reciprocate. The inverted T-block slides back and forth along the T-shaped slide groove 22 under the reciprocating rotation of the threaded rod 242. At this time, the detection roller 1 513 rubs the reciprocating plywood to be tested.

[0043] After the detection roller 1 513 rubs against the plywood to be tested for a period of time, the reciprocating motor 241 is stopped, and the telescopic push rod 1 516 is controlled to extend and push the E-type connecting plate 515 and the three racks 2 514. When the three racks 2 514 move to the left, they mesh with the corresponding linkage gear 511, and the linkage gear 511 and the detection block 1 512 arranged thereon rotate, so that the angle between the detection roller 1 513 and the plywood to be tested changes. At this time, the electric slider 41 is controlled to move downward until the detection roller 1 513 is in contact with the upper surface of the plywood to be tested, and the reciprocating motor 241 is continuously started to make the detection roller 1 513 rub against the plywood to be tested back and forth. After the friction continues for a period of time, the above steps are repeated to complete the wear resistance detection of plywood at different angles.

[0044] It should be noted that while changing the angle between the detection roller 513 and the plywood, the electric slider 41 is controlled to continue to move downward, and the detection roller 513 applies different degrees of force to the upper surface of the plywood to simulate the actual use environment of the plywood, so that the detection result is more accurate.

[0045] Please refer to Figure 7 , Fig. 9 and Fig.10 The detection component 2 52 includes a rotating motor 521 whose output shaft is fixedly arranged inside the circular through groove 45 with the output shaft facing downward. A disc 522 is fixedly arranged on the outer wall of the output shaft of the rotating motor 521. An annular mounting sleeve 523 is fixedly arranged at the center position of the lower end surface of the disc 522 in the vertical direction. The outer wall of the annular mounting sleeve 523 is provided with three avoidance grooves 5231 extending up and down in the circumferential direction. Ear seats 524 are fixedly arranged on the outer wall of the annular mounting sleeve 523 and below the three avoidance grooves 5231. A telescopic push rod 2 525 is fixedly arranged inside the annular mounting sleeve 523 in the vertical direction. The outer wall of the telescopic section of the telescopic push rod 2 525 is fixedly provided with The detection component 2 52 also includes three detection blocks 2 526 corresponding to the positions of the ear seat 524 respectively. The lower end surface of the detection block 2 526 is rotatably provided with three detection rollers 2 5261 extending forward and backward along the left and right directions. The three detection blocks 2 526 are arranged on a side wall close to the annular mounting sleeve 523 and are distributed up and down with two square grooves 5262. A hinge rod 1 527 is rotatably provided in the square groove 5262 at the bottom. The other end of the hinge rod 1 527 is rotatably connected to the ear seat 524. A hinge rod 2 528 is rotatably provided in the square groove 5262 at the top. The other end of the hinge rod 2 528 passes through the corresponding avoidance groove 5231 and is rotatably connected to the connecting sleeve.

[0046] After the plywood has undergone wear resistance testing with the first detection roller 513 for a period of time, control the electric slider 41 to move upward away from the plywood, and then control the reciprocating motor 241 to drive the threaded rod 242 to rotate, causing several plywood boards and the L-shaped support plate 23 to move to the right. At this time, the rectangular push plates 232 on the front and back sides of the plywood being tested slide along the C-shaped limit frames 32 on both sides, ensuring that the plywood being tested is continuously limited. When the plywood being tested moves to directly below the second detection component 52, stop the reciprocating motor 241.

[0047] Then control the electric slider 41 to move downward so that the outer wall of the second detection roller 5261 is in contact with the upper surface of the plywood being tested. Then start the rotating motor 521 to drive the annular mounting sleeve 523 and the three second detection rollers 5261 to rotate on the upper surface of the plywood being tested. The continuous rotation of the three second detection rollers 5261 conducts secondary wear resistance testing on the upper surface of the plywood being tested. After testing for a period of time, control the telescopic push rod two 525 inside the annular mounting sleeve 523 to extend. At this time, the telescopic section of the telescopic push rod two 525 drives the three first articulated rods 527 to move upward synchronously. The three second detection blocks 526 also move upward synchronously under the drive of the corresponding first articulated rods 527, thereby changing the circular detection area on the upper surface of the plywood. When conducting secondary testing on the plywood, the wear resistance testing of different points on the plywood is completed by continuously changing the detection areas of the three second detection blocks 526.

[0048] It should be noted that while changing the circular detection area, the electric slider 41 also moves downward to apply different forces to the upper surface of the plywood, secondarily simulating the actual use environment of the plywood, thereby further improving the accuracy of the detection.

[0049] Working process: S1: Manually push several plywood boards to be tested onto the support plate 2.

[0050] S2: Start the external motor to control the two first racks 31 to drive the two C-shaped limit frames 32 to move closer synchronously. The two C-shaped limit frames 32 push the rectangular push plates 232 on both sides to limit and fix several plywood boards on the support plate 2.

[0051] S3: Control the electric slider 41 on the mounting plate 4 to move downward so that the detection roller 1 513 is in contact with the upper surface of the plywood to be tested, and then start the reciprocating motor 241 to drive the L-shaped carrier plate 23 and the plurality of plywoods to move back and forth left and right. When the plywoods move back and forth, the detection roller 1 513 rubs the upper surface of the plywood. After a period of friction, control the telescopic push rod 1 516 to drive the E-shaped connecting plate 515 and the three racks 2 514 to move leftward so that the racks 2 514 are respectively meshed with the corresponding linkage gears 511 and drive the linkage gears 511 and the detection block 1 512 to rotate. Control the electric slider 41 to move downward so that the detection roller 1 513 is in contact with the plywood to be tested, and continue to reciprocate the plywood to complete the wear resistance test at different angles. Repeat the above steps to complete the wear resistance test of the plywood at different angles by the detection block 1 512.

[0052] S4: After the detection roller 1 513 has been detecting for a period of time, the electric slider 41 is controlled to rise. At the same time, the threaded rod 242 is controlled to rotate and drive the L-shaped carrier plate 23 and several plywood boards to move to the bottom of the detection roller 2 5261. Then the electric slider 41 descends so that the detection roller 2 5261 is in close contact with the upper surface of the plywood. The rotating motor 521 is started to drive the three detection rollers 2 5261 to perform a rotational wear resistance test on the upper surface of the plywood. After a period of testing, the telescopic push rod 2 525 is controlled to extend to change the wear resistance test area of ​​the three detection rollers 2 5261.

[0053] S5: After the detection roller 2 5261 detects for a period of time, it stops and controls the electric slider 41 to rise away from the plywood, and then the external motor reverses to make the rectangular push plate 232 cancel the limit on the plywood, and several plywoods are taken out and tested. In the same test, the friction at different angles and in different areas is simulated, and if there are only slight or obvious scratches on the surface of the plywood, but it does not affect the use, then the wear resistance of the surface plywood is qualified; if serious deformation or breakage occurs and affects the use, then the wear resistance of the surface plywood is unqualified.
