DETAILED DESCRIPTION

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0031] like Figures 1 to 10 As shown, the present invention includes the following embodiments: Example 1

[0032] A furniture edge banding performance testing device comprises a testing platform 1 and a testing plate 2 on the upper surface of the testing platform 1; two chucks 21 are connected to the upper front side of the testing plate 2; the two chucks 21 can clamp the ends of the sample; a testing plate 3 in the shape of a disc is provided on the front side of the testing plate 2; the testing plate 3 is located directly below the clamped sample; the central axis of the testing plate 3 is perpendicular to the front side of the testing plate 2; a cylinder 11 is fixedly connected to the testing platform 1; the output shaft of the cylinder 11 extends to the front side of the testing plate 2; the output shaft of the cylinder 11 is connected to a movable bar 4 through a tension sensor 12; the testing plate 3 is rotatably connected to the movable bar 4 away from the center of the testing plate 2 through a rotating column 31; a scraper 5 is provided in contact with the curved outer wall of the testing plate 3; the scraper 5 is connected to the movable bar 4; the testing plate 3 rotates after being separated from the sample; the scraper 5 can scrape off impurities on the curved outer wall of the testing plate 3.

[0033] In this embodiment, the movable bar 4 is placed horizontally; the guide rod 13 is fixedly connected to the upper surface of the detection platform 1; the guide rod 13 passes through the movable bar 4 and is slidably connected to the movable bar 4; a driving groove 22 is vertically arranged on the front side of the detection plate 2; the groove wall of the lower half of the driving groove 22 is evenly and adjacently arranged with tooth grooves 23; the tooth block 6 is slidably connected in the tooth groove 23; the tooth block 6 is connected to the bottom of the tooth groove 23 by a first spring 61; a guide surface 62 is arranged on the end of the tooth block 6 away from the first spring 61 and tilted upward; the center of the detection disk 3 facing the detection plate 2 is fixed to the gear 32; the gear 32 extends into the driving groove 22 and is unidirectionally meshed with multiple tooth blocks 6.

[0034] During operation, after cutting the sample to the required length, the staff opens the chuck 21, and extends the end of the sample into the chuck 21 with the bonding surface of the sample facing downward, so that the end of the sample is clamped by the chuck 21. Then the controller controls the cylinder 11 to extend, so that the cylinder 11 drives the movable bar 4 to move upward, and the movable bar 4 moves along the axial direction of the guide rod 13 during the upward movement. The movable bar 4 drives the rotating column 31 to move upward during the upward movement, and the detection disk 3 is driven to move upward during the upward movement of the rotating column 31. The curved outer wall of the detection disk 3 is brought into contact with the bonding surface of the sample during the upward movement, and the bonding surface of the sample sticks to the curved outer wall of the detection disk 3. Then the cylinder 11 is controlled to shorten, and the tension sensor 12 is pulled downward during the shortening of the cylinder 11. The device 12 will drive the movable bar 4, and the movable bar 4 can move downward along the axial direction of the guide rod 13. During the downward movement of the movable bar 4, the rotating column 31 will be driven downward, and during the downward movement of the rotating column 31, the detection disk 3 will be driven downward. During the downward movement of the detection disk 3, the gear 32 will be driven to move in the upper half of the driving groove 22, so the gear 32 will not come into contact with the tooth block 6. In addition, the curved outer wall of the detection disk 3 is bonded by the bonding surface of the sample, so the detection disk 3 will not rotate during the process of breaking away from the contact with the sample, so that the detection disk 3 can move downward stably. During the downward movement, the detection disk 3 will be subjected to the bonding force between the sample and the tension sensor 12. The tension force received is recorded in time. After the detection disk 3 continues to move downward, it will break away from the contact with the sample, and then the tension sensor 12 is calculated. If the value displayed by the tension sensor 12 is lower than the standard value, it means that the adhesion of the sample is unqualified, otherwise it is qualified. Then the cylinder 11 will drive the movable bar 4 to continue to move downward. During the downward movement of the movable bar 4, the rotating column 31, the detection disk 3 and the gear 32 will be driven downward. During the downward movement of the gear 32, it will enter the lower half from the upper half of the driving groove 22. Then, after the gear 32 enters the lower half in the driving groove 22, it will contact the tooth block 6. However, since the guide surface 62 is inclined at one end of the tooth block 6 away from the first spring 61, the guide surface 62 will be squeezed during the downward movement of the gear 32, so that the tooth block 6 will be compressed to overcome the first spring 61 and retract into the corresponding tooth groove 23, so that the gear 32 can smoothly pass over multiple tooth blocks 6. , so that the gear 32 moves to the lower limit position in the driving groove 22, and then the cylinder 11 will extend to drive the movable bar 4 to move upward. During the upward movement of the movable bar 4, the rotating column 31, the detection disk 3 and the gear 32 will be driven upward. During the upward movement of the gear 32 in the driving groove 22, it will mesh with multiple tooth blocks 6. Since the guide surface 62 on the tooth block 6 is inclined upward, the gear 32 cannot squeeze the guide surface 62 during the downward movement in the driving groove 22, so that the gear 32 and the multiple tooth blocks 6 can be meshed and transmitted. During the meshing transmission process, the gear 32 will drive the detection disk 3 to start rotating. During the rotation of the detection disk 3, it will produce relative movement with the scraper bar 5. The scraper bar 5 scrapes off the residual adhesive material on the detection disk 3. After the adhesive material on the curved surface of the detection disk 3 is scraped off,Avoid residual adhesive material on the curved surface of the test disk 3 affecting the accuracy of the next sample test, so that the accuracy of the performance test of the edge banding is improved; during the rotation of the test disk 3, the curved surface of the test disk 3 will be cleaned and returned to its original position, and the gear 32 will also be separated from the lower half of the driving groove 22 and enter the upper half, and the tested sample clamped on the chuck 21 will be removed and replaced with a new sample, and then the test disk 3 will be controlled to move up again, and this process will be repeated;,

[0035] The present invention controls the detection disk 3 to rotate after completing the edge banding adhesive performance test, so that the adhesive material on the detection disk 3 is scraped off by the scraper 5, thereby avoiding the residual adhesive material on the curved surface of the detection disk 3 affecting the accuracy of the next sample test, thereby improving the accuracy of the edge banding performance test. Example 2

[0036] The curved outer wall of the detection disk 3 is provided with a slot 33; a block 34 is slidably connected in the slot 33; the block 34 is connected to the bottom of the slot 33 via a second spring 35; the cross-section of the scraper 5 is triangular; the edges of the scraper 5 are in contact with the curved outer wall of the detection disk 3.

[0037] In this embodiment, the block 34 is slidably and sealedly connected to the slot 33; an adjustment slot 36 is provided in the detection disk 3; an adjustment plate 37 is slidably and sealedly connected to the adjustment slot 36; the adjustment plate 37 is connected to a bolt 38 on the side facing away from the detection plate 2; the bolt 38 passes through the rotating column 31 and extends to the outside; the bolt 38 is threadedly connected to the rotating column 31; the slot wall of the adjustment slot 36 close to the detection plate 2 is connected to the slot 33 through the air hole 39.

[0038] When working, the edge banding strip can be used to bandage the edges of various types of boards. Different types of boards have different roughness. For example, the cross-sectional roughness of solid wood boards and particle boards is different. In this way, the staff will adjust the surface roughness of the detection plate 3 according to the detection requirements. If it is necessary to increase the surface roughness of the detection plate 3, screw the bolt 38. The bolt 38 will drive the adjustment plate 37 to slide in the adjustment groove 36. The adjustment plate 37 divides the adjustment groove 36 into a rod cavity and a rodless cavity. The rod cavity is connected to the outside world, and the rod cavity is connected to the outside world. The air hole 39 is connected with the card slot 33. When the adjusting plate 37 approaches the detection plate 2, the space of the rodless cavity will become smaller. The rodless cavity is filled with a medium. When the rodless cavity is pressurized, the medium will be squeezed into the card slot 33 along the air hole 39, so that all the card blocks 34 will overcome the second spring 35 and extend out of the corresponding card slot 33, thereby increasing the friction force on the curved surface of the detection disk 3. If it is necessary to reduce the friction force on the curved surface of the detection disk 3, the bolt 38 is screwed in the reverse direction to drive the adjusting plate 37 away from the detection plate 2, so that the rodless cavity increases in size. The clamping block 34 is pressed against the scraper 5, and the scraper 5 is pressed against the scraper 5. The scraper 5 is pressed against the scraper 5, and the scraper 5 is pressed against the scraper 5. The scraper 5 is pressed against the scraper 5, and the scraper 5 is pressed against the scraper 5. After the test disc 3 is separated from the sample and continues to move downward, the test disc 3 drives the gear 32 to enter the lower half of the driving slot 22, and after the test disc 3 moves upward again, the gear 32 and the tooth block 6 are meshed to drive the test disc 3 to rotate, and the test disc 3 drives the block 34 to contact the scraper 5, and the scraper 5 with a triangular cross-section scrapes the curved surface of the test disc 3. The block 34 retracts to the corresponding slot 33 under the pressure of the scraper 5, so that the scraper 5 does not affect the scraping of the adhesive material on the curved surface of the test disc 3 on the one hand, and can smoothly pass over the block 34 on the other hand;

[0039] In this embodiment, the adjusting bolt 38 drives the adjusting plate 37 to move in the adjusting groove 36, so that the roughness of the curved surface of the detection disk 3 is changed, and the detection disk 3 can simulate the bonding of different types of materials and edge banding strips, so that the edge banding strips can be tested for bonding performance under different types of plates, and the detection range is wider. Example 3

[0040] A compensation groove 24 is provided at the upper front side of the detection plate 2; the compensation groove 24 is provided corresponding to the chuck 21; a compensation block 25 is slidably connected in the compensation groove 24; two compensation blocks 25 are connected to the corresponding compensation groove 24 wall on one side close to each other through a third spring 26; the chuck 21 is fixedly connected to the corresponding compensation block 25; the upward movement degree of the detection disk 3 is proportional to the sample bonding range.

[0041] In this embodiment, a pressing groove 27 is provided on the front side of the detection plate 2; the number of the pressing grooves 27 is two, and they are arranged in an inverted eight-shape; the two pressing grooves 27 are arranged close to each other at the lower end; a pressing rod 7 is slidably connected in the pressing groove 27; the pressing rod 7 is connected between one end of the pressing groove 27 and the upper end of the corresponding pressing groove 27 through a fourth spring 71; the end of the pressing rod 7 located outside the pressing groove 27 is rotatably connected to a pressing roller 72.

[0042] In this embodiment, an annular groove 73 is disposed on the outer wall of the pressing roller 72 ; an annular pad 74 is disposed in the annular groove 73 ; the annular pad 74 is made of an elastic material, such as rubber.

[0043] During operation, the gear 32 in the initial state is located at the middle position of the driving groove 22, and the detection disk 3 moves up and approaches the sample under control. When the top position of the curved surface of the detection disk 3 contacts the sample, the detection disk 3 will squeeze the pressing roller 72 across the sample, and the pressing roller 72 can give the sample a reaction force, so that the sample is pressed on the curved surface of the detection disk 3. Since the pressing roller 72 is provided with an annular groove 73, and an annular pad 74 is provided in the annular groove 73, the pressing roller 72 can be applied to the curved surface of the detection disk 3 across the sample, so that the sample can be pressed and bonded to the detection disk 3, thereby ensuring the bonding effect between the sample and the curved surface of the detection disk 3; the area of ​​the sample bonded to the curved surface of the detection disk 3 increases as the detection disk 3 moves upward, and during the upward movement of the detection disk 3, the middle position of the sample will be pushed up, so that the middle position of the sample will bend upward, thereby pulling the end chuck 21 of the sample, and the chuck 21 will drive the compensation block 25 to overcome the activity of the third spring 26 in the compensation groove 24. , when the two chucks 21 approach each other, the sample will be bent upward better, so that more parts of the sample will contact the curved surface of the detection disk 3. As the detection disk 3 moves upward, the detection disk 3 will lift the pressing roller 72 through the sample, and the pressing roller 72 is rotatably connected to the pressing rod 7, reducing the friction between the pressing rod 7 and the sample and avoiding sample wear. Since the two pressing grooves 27 are in an inverted eight-shaped shape, during the upward movement of the detection disk 3, the two pressing rods 7 will overcome the fourth spring 71 and move along the corresponding pressing groove 27, so that the two pressing rollers 72 move away from each other, so that the pressing roller 72 can move and press the sample bonded to the curved surface of the detection disk 3, so that the sample is better bonded to the curved surface of the detection disk 3, simulating the sample bonding plate in actual use, and improving the detection accuracy of the edge banding strip; after the sample and the detection disk 3 are bonded, the detection disk 3 will move downward, the third spring 26 and the fourth spring 71 will be reset, and the tension sensor 12 will record the value;

[0044] This embodiment changes the area of ​​the sample bonded to the curved surface of the test disk 3 by controlling the upward movement distance of the test disk 3, thereby being able to perform bonding performance tests on edge banding strips with different bonding areas, with a wider testing range; in addition, the sample is pressed and bonded to the curved surface of the test disk 3 by the pressing roller 72, thereby increasing the strength with which the sample adheres to the test disk 3, thereby improving the accuracy of the edge banding performance test. Example 4

[0046] During operation, when the gear 32 moves upward at the lower limit position of the driving groove 22, the gear 32 and the tooth block 6 generate meshing transmission, and the gear 32 will drive the detection disk 3 to rotate, and the adhesive material on the detection disk 3 passes through the scraper bar 5 from bottom to top, and the scraper bar 5 scrapes the adhesive material on the detection disk 3. During the upward movement of the scraper bar 5, the scraper bar 5 is pulled against the bottom of the vertical groove 28 by the elastic rope 51, but the bottom of the vertical groove 28 is corrugated, so the bottom of the vertical groove 28 will squeeze the end of the scraper bar 5, and with the cooperation of the elastic rope 51, the scraper bar 5 moves in the first triangular groove 81 and the second triangular groove 41, thereby changing the contact position between the scraper bar 5 and the detection disk 3 and reducing wear. More importantly, the adhesive material on the scraper bar 5 is pulled together by the notches of the first triangular groove 81 and the second triangular groove 41, so as to facilitate the falling off of the adhesive material on the scraper bar 5, realize the self-cleaning of the scraper bar 5, and ensure the cleaning effect of the adhesive material on the detection disk 3 by the scraper bar 5.
