Description

Technical Field

[0001] This utility model relates to the field of plastic product testing technology, specifically a packaging box handle strength testing device. Background Technology

[0002] As an important part of the packaging structure, the handle of the packaging box needs to be tested for tensile strength before leaving the factory. Generally, a tensile testing machine is used to test the handle.

[0003] A search of existing patents (publication number: CN118654993A) reveals that the handle strength testing device and method can effectively avoid the problem of handle detachment caused by poor handle connection strength and insufficient testing precision.

[0004] However, the above technical solution still has certain drawbacks. The device fixes the handle with a fixing mechanism and then tests the strength of the handle. After the test is completed, the handle needs to be removed and the untested handle needs to be re-fixed, which is time-consuming and affects the efficiency of the handle test. Therefore, a packaging box handle strength testing device is proposed. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a packaging box handle strength testing device to solve the technical problems mentioned in the background.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a packaging box handle strength testing device, comprising a workbench, an alternating component at the top of the workbench, and a fixing component on the alternating component;

[0007] The alternating assembly includes two support frames fixed to the top of the workbench. Each support frame has an electromagnetic slide rail at its top, and an electromagnetic slider slides along the electromagnetic slide rail. A movable plate is fixed to the top of each electromagnetic slider. Between the two support frames, two support frames fixed to the top of the workbench are provided. Each support frame has an electromagnetic slide rail at its top, and an electromagnetic slider slides along the electromagnetic slide rail. A fixed plate is fixed to the top of each electromagnetic slider. A vertical shaft is slidably connected within the fixed plate. A movable plate is fixed to the top of the vertical shaft. A horizontal bar is fixed to the bottom of the vertical shaft. An L-shaped movable rod is fixed to the side of the horizontal bar away from the vertical shaft. A vertical plate for the L-shaped movable rod to slide along is provided between the two support frames. V-shaped grooves are formed on both sides of the vertical plate.

[0008] As a preferred technical solution, a U-shaped frame is fixed to one side of the top of the workbench, an electric push rod is installed at the top of the U-shaped frame, a pull plate is fixed to the end of the movable rod of the electric push rod, and a detection device is provided on the pull plate.

[0009] As a preferred technical solution, the first movable plate and the second movable plate are on the same horizontal plane, and the bottom end of the pull plate is in contact with the first movable plate.

[0010] As a preferred technical solution, one end of the L-shaped moving rod is disposed in the V-shaped sliding groove and slidably connected thereto.

[0011] As a preferred technical solution, the fixing component includes fixing seats respectively installed on both sides of the top of the first movable plate and the second movable plate. An L-shaped plate is provided on one side of the fixing seat. A threaded screw is rotatably connected to the top of the L-shaped plate. A round shaft is fixed to the bottom of the threaded screw. A movable seat is rotatably mounted on the outer wall of the curved surface of the round shaft.

[0012] As a preferred technical solution, the top of the fixed seat is fixed with a protrusion, and the fixed seat is located directly below the movable seat.

[0013] In summary, the present invention has the following main advantages:

[0014] This invention uses a movable base to gradually fit into a fixed base, thus securing the handle of the packaging box. This prevents the handle from detaching at both ends during strength testing, which would affect testing efficiency. Simultaneously, by alternating the movement of movable plates one and two, when testing the handle on movable plate one, an electric push rod drives a pull plate upwards, pulling the fixed handle upwards to perform a tensile strength test. Meanwhile, the operator fixes any handles not yet tested onto movable plate two for further testing, achieving continuous testing and significantly improving the efficiency of packaging box handle testing.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0023] The embodiments of this utility model will be described below based on its overall structure.

[0024] A packaging box handle strength testing device, such as Figure 1-4 As shown, it includes a worktable 100, an alternating component 200 at the top of the worktable 100, and a fixing component 300 on the alternating component 200;

[0025] The alternating assembly 200 includes support frames 210 fixed to both sides of the top of the worktable 100. Each support frame 210 has an electromagnetic slide rail 220 mounted on its top. An electromagnetic slider 230 slides on the electromagnetic slide rail 220. A movable plate 240 is fixed to the top of the electromagnetic slider 230. Between the two support frames 210 are two support frames 250 fixed to the top of the worktable 100. Each support frame 250 has an electromagnetic slide rail 260 mounted on its top. An electromagnetic slider 270 slides on the electromagnetic slide rail 260. The top of the electromagnetic slider 270 is fixed with a fixed plate 280. A vertical shaft 290 is slidably connected inside the fixed plate 280. A movable plate 2910 is fixed at the top of the vertical shaft 290. A horizontal bar 2920 is fixed at the bottom of the vertical shaft 290. An L-shaped movable rod 2930 is fixed on the side of the horizontal bar 2920 away from the vertical shaft 290. A vertical plate 2940 is provided between the two sets of support frames 250 for the L-shaped movable rod 2930 to slide. V-shaped grooves 2941 are provided on both sides of the vertical plate 2940.

[0026] The staff places the handle on the movable plate 240 and fixes it with the fixing component 300. Then, the electromagnetic sliders 230 and 270 move on the electromagnetic rails 220 and 260 respectively, causing the movable plate 240 and the movable plate 2910 to move relative to each other. When the movable plate 2910 moves, it drives the vertical shaft 290, the horizontal bar 2920 and the L-shaped moving rod 2930 to move synchronously. The L-shaped moving rod 2930 slides along the V-shaped slide groove 2941, which causes the horizontal bar 2920 and the vertical plate 2940 to descend. This allows the movable plate 240 and the movable plate 2910 to move alternately. When the handle on the movable plate 240 is being tested for strength, the staff fixes the handles that are not yet tested on the movable plate 2910 to wait for testing, thus achieving continuous testing and greatly improving the testing efficiency of the packaging box handles.

[0027] Please refer to this carefully. Figure 1 A U-shaped frame 110 is fixed on one side of the top of the workbench 100. An electric push rod 120 is installed on the top of the U-shaped frame 110. A pull plate 130 is fixed to the end of the movable rod of the electric push rod 120. A detection device 140 is provided on the pull plate 130.

[0028] The strength of the packaging box handle can be tested by setting the pull plate 130, and the strength data of the handle can be recorded in real time by setting the testing device 140.

[0029] Please refer to this carefully. Figures 2 to 4 The first movable plate 240 and the second movable plate 2910 are on the same horizontal plane. The bottom end of the pull plate 130 is attached to the first movable plate 240. One end of the L-shaped movable rod 2930 is located in the V-shaped sliding groove 2941 and is slidably connected to it.

[0030] By attaching the pull plate 130 to the movable plate 240, the pull plate 130 can be pulled on the handle when it moves upward via the electric push rod 120, thus testing its strength.

[0031] Please refer to this carefully. Figure 1 and Figure 4 The fixing component 300 includes fixing seats 310 respectively installed on both sides of the top of the first movable plate 240 and the second movable plate 2910. An L-shaped plate 320 is provided on one side of the fixing seat 310. A threaded screw 330 is rotatably connected to the top of the L-shaped plate 320. A round shaft 331 is fixed to the bottom of the threaded screw 330. A movable seat 340 is rotatably mounted on the outer curved surface of the round shaft 331. A protrusion 311 is fixed to the top of the fixing seat 310, and the fixing seat 310 is located directly below the movable seat 340.

[0032] The staff inserts the grooves at both ends of the packaging box handle into the protrusions 311 on the two sets of fixing seats 310, and then rotates the threaded screw 330, causing the threaded screw 330 to rotate and move downward through the L-shaped plate 320. This causes the movable seat 340 to move downward synchronously under the action of the round shaft 331, so that the movable seat 340 gradually fits into the fixing seat 310, thus fixing the packaging box handle and preventing the ends from falling off during the strength test of the handle, which would affect the testing efficiency. Then, the electric push rod 120 drives the pull plate 130 upward, causing the pull plate 130 to pull the fixed handle upward, thus realizing the tensile strength test of the handle.

[0033] In use, the handle is placed on the movable plate 240 and fixed by the fixing component 300. Then, the electromagnetic sliders 230 and 270 move on the electromagnetic rails 220 and 260 respectively, causing the movable plate 240 and the movable plate 2910 to move relative to each other. When the movable plate 2910 moves, it drives the vertical shaft 290, the horizontal bar 2920 and the L-shaped movable rod 2930 to move synchronously. The L-shaped movable rod 2930 slides along the V-shaped groove 2941, which causes the horizontal bar 2920 and the vertical plate 2910 to move synchronously. The device descends by 40, enabling the alternating movement of movable plate 240 and movable plate 2910. When performing strength testing on the handle on movable plate 240, the electric push rod 120 drives the pull plate 130 upward, causing the pull plate 130 to pull the fixed handle upward, thus performing a tensile strength test on the handle. At this time, the operator fixes the handles that are not yet tested on movable plate 2910 to await testing, thereby achieving continuous testing and significantly improving the testing efficiency of packaging box handles. All parts not involved in this device are the same as or can be implemented using existing technologies.
