Description
Technical Field
[0001] This utility model belongs to the technical field of composite wood door testing equipment, and in particular relates to an environmentally friendly wood door flatness testing structure. Background Technology
[0002] Environmentally friendly wooden doors made of solid wood composite materials require leveling of the glued layers and a levelness test of the newly glued door body due to their multi-layered structure and gluing process.
[0003] Existing flatness testing devices for environmentally friendly wooden doors are designed to be rolled and tested while attached to the upper wall of the door and unfolded along the same plane. After being rotated 90 degrees by a steering mechanism, they are rolled and tested again. However, the testing structure is relatively complex and lacks flexibility, which is not conducive to the rapid testing of the flatness of the glued door. Utility Model Content
[0004] The technical problem this invention aims to solve is to quickly detect the flatness of the adhesive layer of composite wood doors, enabling omnidirectional movement, enhancing the flexibility of the detection structure, and improving detection efficiency.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: an environmentally friendly wooden door flatness detection structure, including a bearing plate, with support legs fixedly connected to both sides of the bottom of the bearing plate, and also including a vertical plate, a drive assembly, a moving rod, and a floating measuring mechanism. The vertical plate is fixedly connected to the upper two sides of the bearing plate, and a sliding groove is opened in the vertical plate. The drive assembly is rotatably connected between the opposite side walls of the sliding groove. The moving rod is slidably disposed in the sliding groove and is adjusted by moving along the length direction of the bearing plate through the drive assembly. An adjustment groove is opened in the middle of the moving rod, and the floating measuring mechanism is slidably disposed in the adjustment groove and moves synchronously with the moving rod.
[0006] Furthermore, a limiting plate is fixedly connected between the symmetrical uprights. The limiting plate is located at one end of the bearing plate and is arranged in a right-angled triangle for limiting and supporting one end of the environmentally friendly wooden door.
[0007] Furthermore, the floating measuring mechanism includes a connecting sleeve, a sliding rod, a baffle, and a detection component. The connecting sleeve extends from top to bottom through an adjustment groove and is slidably disposed within the adjustment groove via a sliding plate. The sliding rod extends through the connecting sleeve and is slidably disposed within the connecting sleeve. The baffle is fixedly connected to the bottom of the sliding rod, and the detection component is movably connected to the bottom wall of the baffle.
[0008] Furthermore, the sliding plate is fixedly connected to the outer wall of the connecting sleeve and is arranged symmetrically in the upper and lower parts, and slides in contact with the upper and lower side walls of the moving rod; a stop block is fixedly connected to the upper end of the sliding rod, and a support spring is wound around the outer wall of the sliding rod, and the support spring is located between the bottom end of the connecting sleeve and the upper wall of the baffle.
[0009] Furthermore, the detection component includes a limiting sleeve and a detection ball. The limiting sleeve is fixedly connected to the bottom wall of the baffle, and the detection ball is rotatably connected inside the limiting sleeve, with the bottom of the detection ball exposed at the bottom end of the limiting sleeve.
[0010] Furthermore, the drive assembly includes a screw, which is rotatably connected between opposite sidewalls of the slide groove. The screw passes through the end of the moving rod and is threadedly connected to the moving rod. One end of the screw extends through the slide groove to the outside of the upright plate. A drive wheel is fixedly connected to the end of the screw extending out of the slide groove. A belt is wound between the symmetrical drive wheels. A rotary motor is installed on one side of the screw away from the drive wheel.
[0011] After adopting the above structure, the beneficial effects of this utility model are as follows: For the flatness detection of composite wood doors, the door body is placed horizontally using a bearing plate, and one side of the door body is attached to the side wall of the limiting plate. The floating measuring mechanism moves along the length direction of the bearing plate via a sliding rod, which in turn drives the floating measuring mechanism to move. The bottom of the floating measuring mechanism slowly rises along the inclined side of the limiting plate until it contacts the upper wall of the door body. At the same time, the connecting sleeve slides horizontally along the adjustment groove to realize the all-round movement of the bottom detection component.
[0012] By using a spherical detection ball to move and contact the upper wall of the door, and observing the vertical movement distance of the sliding rod, the flatness of the upper wall of the door can be detected, as well as the flatness of the adhesive layer, facilitating the fixed-point detection of uneven positions.

[0022] like Figure 1-7 As shown, an environmentally friendly wooden door flatness testing structure includes a support plate 1, with support legs 2 fixedly connected to both sides of the bottom of the support plate 1. It also includes a vertical plate 3, a drive assembly 4, a moving rod 5, and a floating measuring mechanism 6. The vertical plate 3 is fixedly connected to the upper sides of the support plate 1, and has a sliding groove 7 inside. The drive assembly 4 is rotatably connected between the opposite side walls of the sliding groove 7. The moving rod 5 is slidably disposed within the sliding groove 7 and is adjusted by the drive assembly 4 moving along the length of the support plate 1. An adjustment groove 8 is formed in the middle of the moving rod 5, and the floating measuring mechanism 6 is slidably disposed within the adjustment groove 8 and moves with the moving rod. 5. Synchronous movement adjustment: A limiting plate 9 is fixedly connected between the symmetrical upright plates 3. The limiting plate 9 is located at one end of the bearing plate 1. The limiting plate 9 is set in a right-angled triangle and is used for limiting and supporting one end of the environmentally friendly wooden door. The door body is placed on the bearing plate 1 and its one end abuts against the hypotenuse of the limiting plate 9. By rotating the drive component 4, the moving rod 5 and the floating measuring mechanism 6 are driven to move along the length direction of the bearing plate 1. At the same time, the floating measuring mechanism 6 rises with the hypotenuse of the limiting plate 9, so that the floating measuring mechanism 6 presses against the upper wall of the door body. The flatness of the adhesive layer of the door body is detected by the movement of the floating measuring mechanism 6.
[0023] like Figure 1 , Figure 3 , Figure 5 and Figure 7As shown, in order to enable the floating measuring mechanism 6 to move along the length of the support plate 1, the drive assembly 4 includes a screw 18. The screw 18 is rotatably connected between the opposite side walls of the slide groove 7. The screw 18 passes through the end of the moving rod 5 and is threadedly connected to the moving rod 5. One end of the screw 18 extends through the slide groove 7 to the outside of the vertical plate 3. The end of the screw 18 extending out of the slide groove 7 is fixedly connected to a drive wheel 19. A belt 20 is wound between the symmetrical drive wheels 19. A rotary motor 21 is installed at the end of one screw 18 away from the drive wheel 19. The rotary motor 21 is driven to rotate, which drives the screw 18 on one side to rotate. The symmetrical screws 18 rotate synchronously through the drive wheels 19 connected by the end belt 20, so that the moving rod 5 moves synchronously along the length of the slide groove 7 and drives the floating measuring mechanism 6 to move along the length of the support plate 1.
[0024] like Figure 2-6 As shown, in order to achieve all-round flatness detection of the adhesive layer of the door, the floating measuring mechanism 6 includes a connecting sleeve 10, a sliding rod 11, a baffle 12, and a detection component 13. The connecting sleeve 10 passes through the adjustment groove 8 from top to bottom and is slidably disposed in the adjustment groove 8 via a sliding plate. The sliding rod 11 passes through the connecting sleeve 10 and is slidably disposed in the connecting sleeve 10. The baffle 12 is fixedly connected to the bottom of the sliding rod 11. The detection component 13 is movably connected to the bottom wall of the baffle 12. The detection component 13 slides up and down in the connecting sleeve 10 via the sliding rod 11. At the same time, the connecting sleeve 10 can move horizontally in the adjustment groove 8. Combined with the drive component 4 driving the moving rod 5 to move, the detection component 13 can be moved and adjusted in six directions. It can move and adjust freely in the rectangular plane of the upper wall of the door and achieve flatness detection in the height direction of the upper wall of the door.
[0025] The slide plate is fixedly connected to the outer wall of the connecting sleeve 10 and is arranged symmetrically up and down. It slides in contact with the upper and lower side walls of the moving rod 5. The upper end of the slide rod 11 is fixedly connected to the stop block 14. The outer wall of the slide rod 11 is wrapped with a support spring 15. The support spring 15 is located between the bottom end of the connecting sleeve 10 and the upper wall of the baffle 12. During the movement of the moving rod 5, the support spring 15 presses down the baffle 12, so that the detection component 13 is in contact with the upper wall of the door. At the same time, the stop block 14 limits the upper end of the slide rod 11 and limits the upper and lower sliding stroke of the slide rod 11.
[0026] The detection component 13 includes a limiting sleeve 16 and a detection ball 17. The limiting sleeve 16 is fixedly connected to the bottom wall of the baffle 12, and the detection ball 17 is rotatably connected inside the limiting sleeve 16, with the bottom of the detection ball 17 exposed at the bottom end of the limiting sleeve 16. The bottom of the detection ball 17 contacts the upper wall of the door. By rolling the detection ball 17 in its spherical state, the detection stability is improved, and the accuracy of the flatness detection is increased. When the connecting sleeve 10 moves back and forth or left and right, the detection ball 17 rolls and contacts the upper wall of the door. When the upper wall of the door is not flat, the slide rod 11 moves up and down inside the connecting sleeve 10, thereby realizing the flatness detection of the door's adhesive layer.
[0027] In actual use, the operator loads the door body and places it on the bearing plate 1 from the side away from the limiting plate 9, and slides it horizontally so that one end of the door body abuts against the vertical side wall of the limiting plate 9. In the initial state, the floating measuring mechanism 6 is located on the side of the bearing plate 1 close to the limiting plate 9.
[0028] The drive rotary motor 21 rotates in the forward direction, which drives the screw 18 on one side to rotate in the forward direction. The screw 18 pushes the end of the moving rod 5 to move through the thread. The symmetrical screws 18 rotate synchronously through the drive wheel 19 connected by the end belt 20, so that the moving rod 5 moves synchronously along the length direction of the slide groove 7, and drives the floating measuring mechanism 6 to move along the length direction of the bearing plate 1.
[0029] Meanwhile, the detection component 13 slides up and down in the connecting sleeve 10 via the slide rod 11. The connecting sleeve 10 can move horizontally in the adjustment groove 8. Combined with the movement of the moving rod 5, the detection component 13 can be moved and adjusted in six directions, and can be moved and adjusted freely in the rectangular plane of the upper wall of the door.
[0030] The detection ball 17 rolls to improve detection stability. When the connecting sleeve 10 moves back and forth or left and right, the detection ball 17 rolls and contacts the upper wall of the door. When the upper wall of the door is uneven, the slide rod 11 moves up and down in the connecting sleeve 10 to detect the flatness of the adhesive layer of the door.
