Technical Field

[0001] The utility model relates to the technical field of plywood detection, in particular to a device for detecting the strength of the resin adhesive layer of anti-corrosion plywood. Background Art

[0002] In anti-corrosion plywood, the resin adhesive layer not only plays a bonding role, but may also enhance the anti-corrosion performance of the plywood by adding preservatives. In order to enable the plywood to be used stably, it is necessary to effectively detect the resin adhesive layer.

[0003] After retrieval, the patent document with the publication number CN216695923U discloses a device for detecting the hardness of the resin adhesive layer of plywood. In this detection device, a rotating disk is arranged on the workbench. When in use, the plywood is placed on the workbench, and then the electric push rod is started to drive the hardness tester to move downward, so as to detect the hardness of the plywood.

[0004] However, when the above detection mechanism detects the plywood, it can only perform extrusion detection on one side of the plywood. When it is necessary to comprehensively detect both sides of the plywood, the plywood needs to be taken out and reinstalled, which increases the detection time and reduces the detection efficiency.

[0026] An embodiment of the present utility model discloses a device for detecting the strength of an anti-corrosion plywood resin adhesive layer.

[0027] Embodiment 1

[0028] The present utility model provides a device for detecting the strength of an anti-corrosion plywood resin adhesive layer as shown in Figures 1-3 Figure, which includes a compression testing machine 1. A detection drill bit 2 is fixedly provided at the bottom of the lower pressing end of the compression testing machine 1. Cross bars 3 are slidably penetrated through the upper ends on both sides of the compression testing machine 1. Sleeves 4 are rotatably sleeved at the ends of the cross bars 3. The sleeves 4 are damping sleeves. Positioning collets 5 are fixedly provided on the closer sides of the two sleeves 4;

[0029] An extrusion fixing mechanism for clamping and positioning is commonly provided between the two cross bars 3 and the lower end of the compression testing machine 1. The extrusion fixing mechanism includes a biaxial motor 13. The biaxial motor 13 is fixedly provided at the lower end of the compression testing machine 1. Driving screws 14 are fixedly provided at the output ends on both sides of the biaxial motor 13. The rod walls of the two driving screws 14 penetrate through the compression testing machine 1 and are threadedly sleeved with moving plates 15. The moving plates 15 are fixedly sleeved on the outer sides of the cross bars 3. Strip-shaped holes are opened at the lower ends on both sides of the compression testing machine 1. The moving plates 15 are slidably arranged in the strip-shaped holes.

[0030] Before testing the plywood, place the plywood inside the compression testing machine 1 and start the biaxial motor 13. At this time, the biaxial motor 13 starts to drive the two driving screws 14 to rotate. With the sliding fit in the strip-shaped holes, the moving plate 15 can drive the cross bar 3 to move horizontally, so that the cross bar 3 cooperates with the sleeve 4 to socket and fix the plywood through the positioning jacket 5. Subsequently, the compression testing machine 1 is started, so that the upper moving end drives the detection drill bit 2 to move downward, and the detection drill bit 2 moves downward and squeezes the plywood. When the detection drill bit 2 causes extrusion damage to the resin adhesive layer inside the plywood, record the output pressure of the compression testing machine 1 at this time. Subsequently, the detection drill bit 2 moves upward. During this process, the sleeve 4 drives the jacket 5 to rotate, causing the plywood to flip. Then the detection drill bit 2 moves downward again for detection. At the same time, recording multiple detection data can complete the comprehensive strength detection of the whole plywood, improving the detection efficiency.

[0031] Embodiment 2

[0032] On the basis of Embodiment 1, in order to drive the plywood to flip after the detection drill bit 2 moves upward, as Figures 1-2 shown, a horizontal plate 6 is fixedly provided on the side wall of the lower pressing end of the compression testing machine 1. A vertical plate 7 is fixedly provided at the bottom of the horizontal plate 6. A through hole for the vertical plate 7 to pass through is opened at the lower end of the compression testing machine 1. A flipping detection mechanism for driving flipping is provided between the vertical plate 7 and the sleeve 4. The flipping detection mechanism includes a ratchet gear 8. The ratchet gear 8 is fixedly sleeved with the sleeve 4. A plurality of connecting blocks 9 arranged at intervals are fixedly provided at the lower end of the outer wall of the vertical plate 7. A ratchet tooth 10 is rotatably provided at the end of each connecting block 9. A compression spring 11 is fixedly provided between the ratchet tooth 10 and the vertical plate 7. A limiting plate 12 is in contact with the side of the ratchet tooth 10 away from the compression spring 11. The limiting plate 12 is fixedly connected to the vertical plate 7.

[0033] When the detection drill bit 2 performs the initial downward detection, at this time, under the compression of a plurality of compression springs 11, the vertical plate 7 drives a plurality of ratchet teeth 10 to move downward, so that the ratchet teeth 10 cooperate with the compression springs 11 to rotate under the support of the connecting blocks 9. At this time, the ratchet gear 8 is not pushed by a large force. When one side of the plywood is detected and the detection drill bit 2 starts to move upward, at this time, through the elastic recovery of the compression springs 11 and the bottom support of the limiting plate 12, a plurality of ratchet teeth 10 start to push the teeth of the ratchet gear 8, so that the ratchet gear 8 starts to drive the sleeve 4 to rotate, thereby completing the flipping of the plywood. At the same time, the sleeve 4 is a damping sleeve, so that the plywood can maintain a stable horizontal setting device after flipping, ensuring the detection stability of the plywood after flipping.

[0034] Only some exemplary embodiments of the present utility model have been described by way of illustration. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present utility model. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present utility model.
