Description

Technical Field

[0001] This utility model relates to the field of cardboard box production technology, specifically to a testing device used in cardboard box production. Background Technology

[0002] Cardboard boxes are the most widely used packaging products. Depending on the materials used, there are corrugated cardboard boxes, single-layer cardboard boxes, etc., and they come in various specifications and models. As an indispensable part of modern logistics, cardboard boxes bear the important responsibility of containing, protecting, and presenting products. The physical performance indicators of cardboard boxes become the basis for their quality assessment. The accuracy and reliability of test data require good testing environment conditions, and compression tests need to be carried out on cardboard boxes during the production process.

[0003] A search revealed a corrugated cardboard box compression testing device proposed in Chinese Utility Model Application No. CN202321999064.8. The utility model describes a device that "places the corrugated cardboard box on a main body, and the operator starts motors on both sides of the main body to rotate two sets of screws inside the grooves. Simultaneously, the screw sleeves on the side walls of the screws move left and right, with both ends of the sleeves tightly against the top of the main body. An electric telescopic rod extends or retracts to adjust the height to match the corrugated cardboard box. When the side baffle touches the corrugated cardboard box, the screw rotation stops. The electric telescopic rod then moves downwards, causing the upper pressure plate to touch the top of the corrugated cardboard box. At the same time, a testing mechanism tests the corrugated cardboard box. This operation allows the corrugated cardboard box to be fixed by the upper pressure plate and side baffles before compression testing, and the device is not limited by the size of the corrugated cardboard box, thus improving testing efficiency."

[0004] The current corrugated cardboard box compression testing device requires that, when testing a batch of cardboard boxes, the previously tested cardboard box be removed from the top of the pad and placed on top of the pad and positioned. Finally, the pressure head is moved downwards to test the compression of the next untested cardboard box. However, the process of changing cardboard boxes is cumbersome, time-consuming, and labor-intensive, affecting the testing efficiency. Therefore, a testing device for cardboard box production is proposed to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a testing device for cardboard box production, which has the advantages of high-efficiency testing and solves the problem that the process of changing cardboard boxes is troublesome, time-consuming and labor-intensive, affecting the testing efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a testing device for carton production, comprising a conveyor belt, a frame and a baffle fixedly installed on the top of the conveyor belt, a testing mechanism and a positioning mechanism being provided on the frame, and a limit mechanism being provided on the positioning mechanism;

[0007] The positioning mechanism includes two first electric push rods, which are respectively fixedly connected to both sides of the frame. The output ends of the two first electric push rods pass through the frame and are fixedly installed with positioning plates.

[0008] Furthermore, the detection mechanism includes a second electric push rod, the output end of which passes through the frame and is fixedly mounted with a vertical rod, and a pressure plate is fixedly mounted at the bottom of the vertical rod.

[0009] Furthermore, the limiting mechanism includes two chambers, each with an installation groove on one side of the two positioning plates. The two chambers are fixedly connected inside the two installation grooves. The inner walls of the two chambers are rotatably mounted with threaded rods via first bearings. A knob is fixedly mounted on the side of the threaded rod away from the inner wall of the chamber. Threaded sleeves are threaded onto the outside of the two threaded rods. Movable rods are fixedly mounted through the chambers and fixedly mounted on the outside of the two threaded sleeves. Movable plates are fixedly mounted on the opposite sides of the two movable rods. Circular rollers are provided inside the two movable plates.

[0010] Furthermore, each of the two movable plates has a slider that extends into the positioning plate fixedly installed on its opposite side, and each of the two positioning plates has a groove that matches the slider on its opposite side.

[0011] Furthermore, both of the movable plates have grooves inside, and the roller is rotatably connected inside the grooves via a second bearing.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0013] This inspection device for cardboard box production consists of a conveyor belt, frame, baffles, inspection mechanism, positioning mechanism, and limiting mechanism. First, the limiting mechanism is adjusted to a matching position according to the cardboard box's dimensions. Then, the cardboard box is placed on top of the conveyor belt, which moves the box for loading. Next, the positioning mechanism moves the limiting mechanism to a designated position. When the cardboard box contacts the limiting mechanism, the conveyor belt stops moving the box, positioning it directly below the inspection mechanism. The positioning mechanism then positions the box. Finally, the inspection mechanism inspects the box. After inspection, the positioning mechanism resets the limiting mechanism to release the box from its position. Then, the conveyor belt moves the box for unloading, and the positioning mechanism moves the limiting mechanism to a designated position again until the next box contacts the limiting mechanism. Finally, the next box is positioned and subjected to a compression test. The process of changing cardboard boxes is simple, time-saving, labor-saving, and improves inspection efficiency.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0019] Please see Figure 1-3 The detection device for carton production in this embodiment includes a conveyor belt 1, a frame 2 and a baffle 3 fixedly installed on the top of the conveyor belt 1, a detection mechanism 4 and a positioning mechanism 5 are provided on the frame 2, and a limit mechanism 6 is provided on the positioning mechanism 5.

[0020] Specifically, the staff first adjusts the limiting mechanism 6 to a matching position according to the size of the carton. Then, the carton is placed on top of the conveyor belt 1, and the conveyor belt 1 is used to move the carton for loading. Next, the positioning mechanism 5 is used to move the limiting mechanism 6 to the designated position. When the carton contacts the limiting mechanism 6, the conveyor belt 1 stops moving the carton, so that the carton is directly below the detection mechanism 4. The positioning mechanism 5 is used to position the carton. Finally, the detection mechanism 4 is used to detect the carton. After the detection is completed, the positioning mechanism 5 is used to reset the limiting mechanism 6 to release the carton from the position. Then, the conveyor belt 1 is used to move the carton for unloading. The positioning mechanism 5 is used to move the limiting mechanism 6 to the designated position again until the next carton contacts the limiting mechanism 6. Finally, the next carton is positioned and subjected to a compression test. The process of changing the carton is relatively simple, saving time and effort, and improving detection efficiency.

[0021] In this embodiment, the detection mechanism 4 includes a second electric push rod 41. The output end of the second electric push rod 41 passes through the frame 2 and is fixedly installed with a vertical rod 42. A pressure plate 43 is fixedly installed at the bottom of the vertical rod 42.

[0022] Specifically, by activating the second electric push rod 41, the second electric push rod 41 drives the vertical rod 42 and the pressure plate 43 to move downward, and the pressure plate 43 squeezes the top of the carton.

[0023] In this embodiment, the positioning mechanism 5 includes two first electric push rods 51, which are respectively fixedly connected to both sides of the frame 2. The output ends of the two first electric push rods 51 pass through the frame 2 and are fixedly installed with positioning plates 52.

[0024] Specifically, by activating the two first electric push rods 51, the two first electric push rods 51 drive the two positioning plates 52 to move relative to each other, and the two positioning plates 52 position the carton.

[0025] In this embodiment, the limiting mechanism 6 includes two chambers 61. Each of the two positioning plates 52 has an installation groove on one side facing each other. The two chambers 61 are fixedly connected to the interior of the two installation grooves. A threaded rod 62 is rotatably mounted on the inner wall of each chamber 61 via a first bearing. A knob 63 is fixedly mounted on the side of the threaded rod 62 away from the inner wall of the chamber 61. A threaded sleeve 64 is threaded onto the exterior of each of the two threaded rods 62. A moving rod 65 is fixedly mounted through the chamber 61 and fixedly mounted on the exterior of each of the two threaded sleeves 64. A moving plate 66 is fixedly mounted on one side facing each of the two moving rods 65. A slider extending into the interior of the positioning plate 52 is fixedly mounted on one side of each of the two moving plates 66 facing away from each other. A groove matching the slider is opened on one side facing each of the two positioning plates 52. The cross-section of the groove and the cross-section of the slider are both U-shaped. A circular roller 67 is provided inside each of the two moving plates 66. A groove is opened inside each of the two moving plates 66. The circular roller 67 is rotatably connected to the interior of the groove via a second bearing.

[0026] Specifically, by rotating the knob 63, the knob 63 drives the threaded rod 62 to rotate, and the threaded rod 62 drives the threaded sleeve 64, the moving rod 65, the moving plate 66 and the circular roller 67 to move to the appropriate position so that when the carton comes into contact with the circular roller 67, the carton is located directly below the pressure plate 43.

[0027] The working principle of the above embodiments is as follows:

[0028] The operator first rotates knob 63, which drives threaded rod 62 to rotate. Threaded rod 62 moves threaded sleeve 64, moving rod 65, moving plate 66, and roller 67 to the appropriate position. Then, the carton is placed on top of conveyor belt 1, and conveyor belt 1 is turned on to move the carton for loading. Next, two first electric push rods 51 are activated, moving two positioning plates 52 and two moving plates 66 relative to each other to the designated position. When the carton contacts roller 67, conveyor belt 1 is turned off to stop moving the carton, positioning it directly below pressure plate 43. The two first electric push rods 51 are then activated again, moving the two positioning plates 52 relative to each other to position the carton. Finally, the second electric push rod 41 is activated, moving vertical rod 42 and pressure plate 43 downwards. Pressure plate 43 inspects the carton. After the test is completed, firstly, the two first electric push rods 51 are activated. The two first electric push rods 51 drive the two positioning plates 52 to move in opposite directions to release the carton from its positioning. Then, the conveyor belt 1 is activated to move the carton for unloading. Next, the two first electric push rods 51 are activated again. The two first electric push rods 51 drive the two positioning plates 52 and the two moving plates 66 to move relative to each other to the designated position. When the next carton comes into contact with the roller 67, the conveyor belt 1 is turned off to stop moving the carton, so that the next carton is located directly below the pressure plate 43. Then, the two first electric push rods 51 are activated again. The two first electric push rods 51 drive the two positioning plates 52 to move relative to each other to position the next carton. Finally, the second electric push rod 41 is activated. The second electric push rod 41 drives the vertical rod 42 and the pressure plate 43 to move downward to inspect the next carton. The process of changing the carton is relatively simple, saving time and effort, and improving the inspection efficiency.
