Description

Technical Field

[0001] The utility model relates to the technical field of cartons, in particular to a carton strength detection device. Background Art

[0002] Due to differences in materials and structural models, the strength of the formed cartons will vary. Cartons need to be tested for loading capacity before leaving the factory to ensure that the strength of the cartons meets the standards.

[0003] In fact, the upper and lower ends of the carton need to be folded and fixed, so their structure is different from that of the side panels. When more accurate carton strength data is needed, the strength of the upper and lower end faces and the side panels of the carton need to be tested. However, the current strength detection devices mostly use a downward pressure strength detection method, which requires the carton to be switched back and forth to change the detection position. Utility Model Content

[0004] The utility model aims to at least solve the problem in the prior art that during the process of detecting the upper and lower strength and the side wall strength of the carton, the carton body needs to be turned over manually.

[0005] The present invention provides a carton strength testing device, which is achieved by the following specific technical means: comprising a testing platform, a vertical frame fixed to the rear end of the testing platform, shafts one and two rotating on the vertical frame, telescopic arms sleeved on shafts one and two, and a pressure plate fixedly mounted on the end of each set of telescopic arms, and the two sets of pressure plates can be controlled to approach and swing to the top of the testing platform through the synchronous and distorted rotation of shafts one and two, so as to test the downward pressure strength of the box port placed on the testing platform; when shafts one and two drive the two sets of pressure plates to stand upright and be located on both sides of the carton on the testing platform, the lateral strength of the carton can be tested.

[0006] Preferred technical solution 1: A pressure detector is installed between the pressing plate and the end of the telescopic arm, and the pressure between the pressing plate and the carton is measured by the pressure detector.

[0007] Preferred technical solution two: the telescopic arm includes a fixed arm and a movable arm, one group of the fixed arms is fixed on axis one, and the other group of the fixed arms is fixed on axis two, the movable arms are pulled and slid on the fixed arms, and the ends of the movable arms are fixedly connected to the pressure detector.

[0008] Preferred technical solution three: a screw rod is rotatably provided in the fixed arm, and the movable arm is sleeved on the screw rod through a threaded hole.

[0009] Preferred technical solution four: Gears are sleeved on both the first and second shafts, and the two sets of gears are meshed with each other.

[0010] Preferred technical solution five: When the two groups of pressing plates are placed flat on the same plane, the ends of the two groups of pressing plates are butted against each other.

[0011] The above structure enables this solution to have the following beneficial effects:

[0012] 1. Through axis 1, axis 2, telescopic arms and two sets of pressing plates, the downward pressure end face strength test and side pressure side panel strength test of the carton can be completed without turning the carton over;

[0013] 2. By installing a pressure detector on each set of pressure plates, two sets of data can be obtained at the same time, increasing the accuracy of the data. BRIEF DESCRIPTION OF THE DRAWINGS

The pressure between the pressing plate 6 and the carton is measured by the pressure detector 7, and the data on the two sets of pressure detectors 7 can be cited to each other to avoid the problem of inaccurate data caused by damage to one set of pressure detectors 7. When in use, the two sets of pressing plates 6 can be controlled to approach and swing by the synchronous and distorted rotation of the axis 1 3 and the axis 2 4. To the top of the inspection table 1, the two groups of pressure plates 6 are in the same plane at this time, and the ends of the two groups of pressure plates 6 are butted and contacted, thereby forming a complete inspection plate, and the synchronous contraction of the two groups of telescopic arms 5 is used to realize the downward pressure strength test of the box port placed on the inspection table 1. The contact end surfaces of the two groups of pressure plates 6 are embedded with magnetic suction parts 61, so that the two groups of pressure plates 6 can be attracted and contacted when docked, thereby improving the connection stability of the pressure plates 6 and allowing the two groups of pressure plates 6 to remain in a flat state; and when the axis 1 3 and the axis 2 4 drive the two groups of pressure plates 6 to stand up and be located on both sides of the carton on the inspection table 1, the two groups of pressure plates 6 can be driven to approach each other by the contraction of the two groups of telescopic arms 5 to test the lateral strength of the carton.

The meshing transmission between the gears 8 realizes the control of the synchronous and distorted rotation of shaft 1 3 and shaft 2 4.
