This pressure testing device with a limiting function for carton production allows the user to rotate the adjusting bolt when the carton is placed on top of the base plate. This rotation causes the adjusting bolt to rotate inside the clamping plate via the rotating block, simultaneously pushing the clamping plate to slide against the inner wall of the base plate, causing the anti-slip pad to adhere to the surface of the carton, thus limiting the carton's position. However, this patent still has the following problems in actual use:

[0004] The testing device limits the carton by setting a base plate and an adjusting plate. However, the carton may deform during the pressure test, and the clamping force of the adjusting plate will prevent the carton from deforming. This can easily affect the test data of the carton and cause errors in the test structure.

[0005] Therefore, a testing device for cardboard box production and processing is proposed to solve the problems mentioned above. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-6 This utility model provides a technical solution: a testing device for carton production and processing, including a workbench 1; a support frame 17 is fixedly connected to one side of the top surface of the workbench 1, a lifting frame 18 is slidably connected to the inner side of the support frame 17, a test block 19 is fixedly connected to the middle of the bottom of the lifting frame 18, a pressure plate 20 is fixedly connected to the bottom of the test block 19, a guide rod 22 is fixedly connected to one side of the top surface of the pressure plate 20, a connecting frame 21 is slidably connected to the upper end of the guide rod 22, and a buffer spring 23 is sleeved on the upper end of the guide rod 22; it also includes: a fixing block 2 is fixedly connected to the middle of the top surface of the workbench 1, a locking spring 3 is fixedly connected to one side inside the fixing block 2, a locking block 4 is fixedly connected to one end of the locking spring 3, and a testing platform 5 is arranged above the locking block 4. A movable groove 6 is provided in the middle of the bottom surface, and a locking groove 7 is provided on one side of the inner wall of the movable groove 6. A ball bearing 8 is rotatably connected to the other side of the bottom surface of the workbench 1. The fixed block 2 is slidably connected to the movable groove 6, and the lower end of the locking block 4 is slidably connected to the middle of the top of the fixed block 2. The locking groove 7 is symmetrically provided on the top surface of the inner side of the test bench 5. The ball bearings 8 are symmetrically and evenly distributed on the bottom surface of the test bench 5. The test bench 5 is slidably connected to the top surface of the workbench 1 through the ball bearings 8. By setting a locking spring 3 and a locking block 4 at the top of the fixed block 2, it is easy to lock the test bench 5 stably by locking the locking block 4 in the middle of the locking groove 7. It is also easy to pull the test bench 5 out, which facilitates the quick placement of the carton and makes the use of the testing device more convenient and faster.

[0031] The workbench 1 has a sliding groove 9 on one side of its top surface. A threaded rod 10 is rotatably connected to the middle of the sliding groove 9. A threaded block 11 is threadedly connected to the outer side of the threaded rod 10. A limit spring 12 is fixedly connected to the middle of the upper end of the threaded block 11. A limit block 13 is fixedly connected to the upper end of the limit spring 12. A motor is fixedly connected to one end of the threaded rod 10. The threaded block 11 is slidably connected to the middle of the sliding groove 9. The limit spring 12 and the limit block 13 are set in two sets. The other set of limit spring 12 and limit block 13 is set on the top surface of the test bench 5 away from the sliding groove 9. By setting the limit spring 12 and the limit block 13 at the upper end of the threaded block 11, it is easy to lock the direction of the positioning plate 14, thereby facilitating the positioning plate 14 to quickly position the carton. At the same time, it avoids the influence of the limit rod 16 on the carton test, making the test more accurate.

[0032] The threaded block 11 has a rotatable positioning plate 14 at the middle of its upper end. A limiting groove 15 is provided on one side of the positioning plate 14, and a limiting rod 16 is fixedly connected to the top of the positioning plate 14. The lower end of the limiting block 13 is slidably connected to the middle of the upper end of the threaded block 11. The limiting groove 15 is provided in the middle of the bottom surface of the positioning plate 14 and on the side of the positioning plate 14 near the sliding groove 9. The limiting rod 16, the positioning plate 14, and the limiting groove 15 are arranged symmetrically. Another set of limiting rods 16, positioning plates 14, and limiting grooves 15 is provided on the side of the test platform 5 away from the sliding groove 9. The other set of limiting rods 16 is rotatably connected to one side of the upper end of the test platform 5. The setting of the limiting groove 15 facilitates the engagement of the limiting block 13 with the limiting groove 15, making the adjustment of the position of the positioning plate 14 and the limiting rod 16 more convenient and quick.

[0033] Working principle: When using the testing device for carton production and processing, firstly, by pulling the test platform 5 and sliding it on the top surface of the workbench 1 via the ball bearing 8, the test platform 5 slides on the fixed block 2 on the top surface of the workbench 1 via the moving groove 6. At this time, the locking groove 7 pushes the locking block 4 to retract towards one side of the locking spring 3, and then engages with the locking groove 7 on the other side.

[0034] Secondly, by pulling the limiting rod 16, the limiting rod 16 rotates on one side of the threaded block 11 through the positioning plate 14, thereby causing the limiting block 13 to slide towards the limiting spring 12 and separating the limiting block 13 from the limiting groove 15. When the limiting rod 16 is vertical, the limiting block 13 engages with the limiting groove 15 on the other side, and the carton is placed in the middle of the limiting rod 16. Then, the threaded rod 10 drives the threaded block 11 to slide in the sliding groove 9, thereby clamping both sides of the carton and bringing the pressure plate 20 into contact with the top surface of the carton.

[0035] Finally, pull the limit rod 16 again to make the limit rod 16 drive the positioning plate 14 to rotate, so that the limit rod 16 unfolds and makes the limit rod 16 level with the top surface of the test table 5. The lifting frame 18 in the middle of the stand 17 drives the test block 19 to push the pressure plate 20 to descend. At this time, the guide rod 22 at the top of the pressure plate 20 slides on the connecting frame 21 and causes the buffer spring 23 to reset.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
