[0026] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] refer to Figure 1-4 A device for testing the compressive strength of wooden packaging boxes includes a fixed frame 1 and a wooden packaging box clamping frame 2. A strength testing workbench 3 is fixedly installed in the middle of the bottom inner wall of the fixed frame 1. A first motor 4 is fixedly installed on the right side of the wooden packaging box clamping frame 2. A bidirectional lead screw 5 is fixedly installed at the output end of the first motor 4. The bidirectional lead screw 5 is rotatably installed on the upper and lower sides between the inner walls of the left and right sides of the wooden packaging box clamping frame 2. A transmission gear 6 is fixedly installed on the outer side of the bidirectional lead screw 5. The transmission gear 6 facilitates the rotation of the bidirectional lead screw 5 on the upper and lower sides by a single first motor 4, so that the bidirectional lead screw 5 can drive the clamping plate 7 and the guide plate 8 to move their positions after rotation.

[0028] The transmission gears 6 mesh with each other. Clamping plates 7 are threaded on the left and right sides of the outer side of the double-acting screw 5. Guide plates 8 are threaded on the left and right sides of the outer side of the lower double-acting screw 5. Multiple rotating shafts 9 are provided on the inner side of the guide plates 8. Guide rollers 10 are fixedly installed on the outer side of the rotating shafts 9. A guide assembly is provided above the fixed frame 1. A moving assembly is provided above the fixed frame 1 and the wooden packaging box clamping frame 2.

[0029] The transmission gear 6 can reverse the rotation direction of the bidirectional lead screw 5, so that when the upper bidirectional lead screw 5 drives the clamping plate 7 to clamp and fix the wooden packaging box body 21, the lower guide plate 8 moves away from the wooden packaging box body 21.

[0030] In this embodiment, the guiding assembly includes a first electric telescopic rod 11, a pressure detection device 12, a support frame 13, a conveyor belt 14, and a limiting partition 15. The first electric telescopic rod 11 is fixedly installed on the top of the fixed frame 1, and the pressure detection device 12 is fixedly installed on the output end of the first electric telescopic rod 11, so that the pressure detection device 12 can perform strength detection on the wooden packaging box body 21 after it descends.

[0031] The support frame 13 is fixedly installed on the left and right sides of the bottom inner wall of the fixed frame 1, the conveyor belt 14 is rotatably installed between the left and right inner walls of the support frame 13, and the limiting partition 15 is fixedly installed on the top of the right support frame 13.

[0032] In this embodiment, the moving component includes a limiting frame 16, a second motor 17, a one-way lead screw 18, a sliding frame 19, a second electric telescopic rod 20, and a wooden packaging box body 21. The limiting frame 16 is fixedly installed behind the bottom inner wall of the fixed frame 1. The second motor 17 is fixedly installed on one side of the limiting frame 16. The one-way lead screw 18 is fixedly installed at the output end of the second motor 17. The sliding frame 19 is threaded onto the outside of the one-way lead screw 18. The second electric telescopic rod 20 is fixedly installed on the top of the sliding frame 19. The wooden packaging box body 21 is positioned above the strength testing workbench 3. The wooden packaging box clamping frame 2 is fixedly installed at the output end of the second electric telescopic rod 20.

[0033] In this embodiment, the front upper and lower sides of the wooden packaging box clamping frame 2 are provided with limiting grooves, and the bidirectional screw 5 is rotatably installed inside the limiting groove. The clamping plate 7 and the guide plate 8 are slidably installed inside the limiting groove. In this embodiment, one side of the guide plate 8 is provided with an installation groove, and the rotating shaft 9 is rotatably installed between the inner walls of the front and rear sides of the installation groove. The installation groove facilitates the installation of the rotating shaft 9, making the guide roller 10 more stable during rotation. The guide roller 10 can guide and limit the wooden packaging box body 21, so that the wooden packaging box body 21 is less likely to deviate from its position when the pressure detection device 12 performs pressure detection on the wooden packaging box body 21, and the guide roller 10 does not easily support the wooden packaging box body 21, making the detection result more accurate.

[0034] In this embodiment, the top of the limiting frame 16 is provided with a sliding groove, and the sliding frame 19 is slidably installed on the inner side of the sliding groove; in this embodiment, the clamping plate 7 and the guide plate 8 are provided with threaded holes on one side, the bidirectional screw 5 meshes with the adjacent threaded hole, and the clamping plate 7 is provided with an anti-slip pad on one side; so that after the bidirectional screw 5 rotates, it can drive the clamping plate 7 and the guide plate 8 to move in position through the threaded engagement, so that when the clamping plate 7 clamps the wooden packaging box body 21, the anti-slip pad can increase the friction, making the wooden packaging box body 21 more stable during the movement.

[0035] In this embodiment, a fixing groove is provided on one side of the support frame 13, and the conveyor belt 14 is rotatably installed between the inner walls of the left and right sides of the fixing groove. The fixing groove facilitates the installation of the conveyor belt 14, so that the device does not require workers to move and transport the wooden packaging box body 21, making collection and transportation more convenient and faster.

[0036] Specifically, the conveyor belt 14 on the right can transport the wooden packaging box body 21. The first motor 4 is controlled to drive the bidirectional lead screw 5 to rotate. After rotation, the bidirectional lead screw 5 can drive the clamping plate 7 to slide in the opposite direction through threaded engagement, allowing the clamping plate 7 to clamp and fix the wooden packaging box body 21. The wooden packaging box body 21 can then be moved above the strength testing workbench 3 for strength testing. During the strength testing process, the first motor 4 can be controlled to rotate in the opposite direction, causing the bidirectional lead screw 5 to drive the lower bidirectional lead screw 5 to rotate through the transmission gear 6. The lower bidirectional lead screw 5 can drive the guide plate 8 and the upper guide roller 10 to limit and guide the wooden packaging box body 21. The upper bidirectional lead screw 5 can also drive the clamping plate 7 to move from the wooden packaging box body 21... The first electric telescopic rod 11 detaches from the top, making it difficult for the clamping device to support the wooden packaging box body 21 when the first electric telescopic rod 11 drives the downward pressure detection device 12, thus making the detection result more accurate. After the detection is completed, the clamping plate 7 can be controlled to clamp and fix the wooden packaging box body 21, and the second motor 17 can be controlled to drive the one-way screw 18 to rotate, so that the one-way screw 18 can drive the sliding frame 19 to slide, so that the sliding frame 19 can move the clamped wooden packaging box body 21 to the top of the left conveyor belt 14. The limiting partition 15 can limit the wooden packaging box body 21 to prevent the wooden packaging box body 21 from detaching from the top of the conveyor belt 14. The second electric telescopic rod 20 makes it easier to prevent the clamped wooden packaging box body 21 from colliding during the movement.

[0037] The compressive strength testing device for wooden packaging boxes provided by this utility model has been described in detail above. Specific embodiments have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core idea of ​​this utility model.
