Description

Technical Field

[0001] This utility model relates to the field of packaging inspection technology, and in particular to a carton handle pull detector. Background Technology

[0002] The cardboard box handle lifting tester is a specialized device for testing the tensile strength and fatigue performance of cardboard box handles. In the dairy industry, milk carton handles need to withstand a weight of 20 kilograms, so their reliability needs to be tested through specific actions, including: lifting up and down: 30 cm high, repeated 10 times; swinging left and right: 60 cm forward stroke, 60 cm reverse stroke, each repeated 10 times.

[0003] Traditional testing methods rely on manual operation, which has the following drawbacks:

[0004] High labor costs and low efficiency: Quality inspectors are mostly women and need to perform repetitive, high-intensity tasks, resulting in high physical exertion and low testing efficiency.

[0005] Inconsistent testing standards: The difficulty in standardizing the force and speed of manual operation leads to deviations in test results;

[0006] Market equipment gap: There is a lack of automated equipment in the existing technology for this type of special testing process, which cannot meet the needs of the industry. Utility Model Content

[0007] This utility model proposes a carton handle lifting detection instrument, which can prevent the handle from falling off through the fixing structure of the hand-shaped shock-absorbing handle, and achieve stable and accurate up and down lifting detection with the help of a cylinder. Furthermore, it can achieve flexible and adjustable left and right swing detection by the cooperation of a swing drive component and a swing arm. It can meet specific detection standards, replace manual operation, and improve the accuracy, reliability and efficiency of detection, thereby solving the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a carton handle lifting detection device, comprising a support base, a support rod fixedly connected to the middle of the upper rear side of the support base, a swing arm rotatably connected to the top front end of the support rod, a swing drive component provided at the top rear end of the support rod, a cylinder fixedly connected to the bottom end of the swing arm, a hand-shaped shock-absorbing handle fixedly connected to the output end of the cylinder, and a power distribution box fixedly connected to the top rear right side of the support base.

[0009] The hand-shaped shock-absorbing handle includes a horizontal U-shaped pull plate. The upper surface of the horizontal U-shaped pull plate is fixedly connected to the output end of the cylinder. An elastic buffer pad is fixedly connected to the lower inner wall of the horizontal U-shaped pull plate. Sliding guide rods are fixedly connected to the top left and right sides of the horizontal U-shaped pull plate. A right-angle rotating baffle is movably connected to the outer surface of the sliding guide rod. A limit plate is slidably engaged at the rear top of the right-angle rotating baffle. The limit plate is fixedly connected to the top of the horizontal U-shaped pull plate.

[0010] Preferably, a rotating retaining ring is fixedly connected to the middle of the swing arm, and a connecting groove that runs through the front and back is provided at the top of the swing arm.

[0011] Preferably, a connecting post is fixedly connected to the top front end of the support rod, and the swivel ring is rotatably connected to the outer surface of the connecting post.

[0012] Preferably, the swing drive includes a drive motor, which is fixedly connected to the top rear side of the support rod, and the output shaft of the drive motor is fixedly connected to an adjustment bracket.

[0013] Preferably, the front side of the adjusting bracket is provided with a connecting slide column, which is slidably connected to the inner surface of the connecting slide groove.

[0014] Preferably, the adjusting bracket includes a rotating plate, the rear bottom of which is fixedly connected to the output shaft of the drive motor, and a sliding groove extending through the center of the rotating plate.

[0015] Preferably, a knob is rotatably connected to the top of the rotating plate, and the bottom end of the knob extends into the interior of the sliding groove and is fixedly connected to a transmission screw.

[0016] Preferably, the outer surface of the transmission screw is threadedly connected to a threaded slider, the outer surface of the threaded slider is slidably connected to the inner surface of the sliding groove, and the connecting slide is fixedly connected to the front side of the threaded slider.

[0017] Preferably, a counter is fixedly connected to the left side of the front surface of the distribution box, and a counter reset button is provided on the right side of the front surface of the distribution box.

[0018] Preferably, a one-button start is provided on the left side of the upper surface of the distribution box, a power indicator light is provided in the middle of the upper surface of the distribution box, and an emergency stop switch is provided on the right side of the upper surface of the distribution box.

[0019] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0020] 1. In this utility model, the stable and precise up-and-down lifting detection of the milk carton handle is achieved through the cooperation between the hand-shaped shock-absorbing handle and the cylinder. The milk carton handle is hung on the elastic buffer pad of the horizontal U-shaped pull plate. The right-angle rotating baffle is rotated to block the opening of the horizontal U-shaped pull plate. Then, the right-angle rotating baffle is slid so that it is locked into the inner side of the limiting plate, thereby fixing the position of the right-angle rotating baffle and preventing the handle from sliding out of the horizontal U-shaped pull plate. Subsequently, the cylinder drives the hand-shaped shock-absorbing handle to slide up and down reciprocally. Based on this principle, this structure first achieves multiple fixation... The fixed structure ensures the stability of the handle during the testing process, effectively preventing test interruptions or data distortion caused by the handle falling off. Secondly, the elastic buffer pad simulates the cushioning effect of manual gripping, reducing additional damage to the handle caused by hard contact and making the test results more consistent with actual usage scenarios. Furthermore, the cylinder-driven up-and-down reciprocating sliding can operate strictly according to a height of 30 cm and a repetition count of 10 times, ensuring the consistency of each lifting action, solving the problem of inconsistent manual operation force and stroke, and significantly improving the accuracy and reliability of up-and-down lifting tests.

[0021] 2. In this utility model, the interaction between the swing drive component and the swing arm enables flexible and adjustable left-right swing detection of the milk carton handle. The drive motor rotates the adjusting bracket, causing the connecting slide column to rotate accordingly. As the connecting slide column slides in the connecting groove, it drives the swing arm to swing back and forth. Simultaneously, rotating the knob causes the transmission screw to drive the threaded slider to slide, thereby adjusting the position of the connecting slide column and thus changing the swing amplitude of the swing arm. Based on this principle, this structure can accurately complete left-right swing detection with a stroke of 60 cm in both the forward and reverse directions, 10 times each, meeting the special testing requirements of Mengniu Dairy. This replaces the high-intensity manual swinging operation, reducing the workload of quality inspectors. Furthermore, the adjustable swing amplitude allows the equipment to adapt to the testing needs of milk carton handles of different specifications and testing standards, expanding the equipment's applicability. It eliminates the need for separate equipment for different testing requirements, greatly improving the flexibility and convenience of testing and increasing testing efficiency.

[0031] The overall effect of Embodiment 1 is as follows: the structural design of the hand-shaped shock-absorbing handle 6 enables quick and stable fixation of the milk box handle; the elastic buffer pad 62 reduces damage to the handle during the testing process; the cylinder 5 enables automated operation of the up and down lifting action; the counter 71 on the power distribution box 7 accurately records the number of lifting actions; and the one-button start button 73 and emergency stop switch 75 improve the convenience and safety of operation, effectively replacing manual up and down lifting operations, ensuring the consistency of lifting height and force each time, and greatly improving the efficiency and accuracy of up and down lifting detection.

[0032] Example 2: As Figure 2 and Figure 3As shown, this utility model provides a technical solution: a rotating retaining ring 31 is fixedly connected to the middle of the swing arm 3, a connecting groove 32 extending through the front and rear is opened at the top of the swing arm 3, a connecting post 21 is fixedly connected to the top front end of the support rod 2, the rotating retaining ring 31 is rotatably connected to the outer surface of the connecting post 21, the swing drive component 4 includes a drive motor 41, the drive motor 41 is fixedly connected to the rear side of the top of the support rod 2, the output shaft of the drive motor 41 is fixedly connected to an adjusting bracket 42, a connecting sliding post 43 is provided on the front side of the adjusting bracket 42, and the connecting sliding post 43 is slidably connected to the inner surface of the connecting groove 32. The adjustment bracket 42 includes a rotating plate 421. The bottom rear side of the rotating plate 421 is fixedly connected to the output shaft of the drive motor 41. A sliding groove 422 that runs through the front and rear is provided in the middle of the rotating plate 421. A knob 423 is rotatably connected to the top of the rotating plate 421. The bottom end of the knob 423 passes through the interior of the sliding groove 422 and is fixedly connected to a transmission screw 424.

[0033] The overall effect of Embodiment 2 is as follows: the cooperation between the rotating ring 31 and the connecting post 21 allows the swing arm 3 to rotate flexibly; the drive motor 41 of the swing drive component 4 provides stable power for the left and right swing of the swing arm 3; and the sliding of the connecting slide post 43 within the connecting slide groove 32 ensures the smoothness of the swing action. The design of the adjusting bracket 42, through the cooperation of the knob 423, the transmission screw 424, and the threaded slider 425, allows for convenient adjustment of the position of the connecting slide post 43, thereby precisely controlling the swing amplitude of the swing arm 3. This not only meets the detection requirements of 60 cm strokes in both the forward and reverse directions but also adapts to the detection needs of different sizes of milk carton handles, expanding the applicability of the equipment and reducing the labor intensity of manual swinging.

[0034] The working principle of the entire device is as follows: First, place the milk carton to be tested on the support base 1, hang the milk carton handle on the elastic buffer pad 62 inside the horizontal U-shaped pull plate 61, rotate the right-angle rotating baffle 64 to block the opening of the horizontal U-shaped pull plate 61, and then slide the right-angle rotating baffle 64 to lock it into the inner side of the limit plate 65 to complete the fixation of the handle. Next, turn on the power supply of the device, and the power indicator light 74 will light up. Press the one-button start button 73 on the distribution box 7, and the device will start working according to the preset program. For the up and down lifting detection, the PLC controller will control the cylinder 5 to start. The output end of the cylinder 5 drives the hand-shaped shock-absorbing handle 6 and the milk carton handle to move up and down reciprocatingly. The lifting height is strictly controlled at 30 cm each time. At the same time, the counter 71 starts to record the number of lifting actions until 10 lifting actions are completed and then stop. For the left and right swing detection, the PLC controller controls the drive electric motor When the machine 41 is started, the output shaft of the drive motor 41 drives the adjusting bracket 42 to rotate, causing the connecting slide column 43 to move in a circle around the output shaft of the drive motor 41. Since the connecting slide column 43 is slidably connected in the connecting slide groove 32 of the swing arm 3, it drives the swing arm 3 to swing back and forth with the connecting column 21 as the fulcrum, realizing the left and right swing detection of the milk box handle. It swings 10 times in both the forward and reverse directions, with each stroke being 60 cm. If it is necessary to adjust the swing amplitude, the knob 423 can be turned to rotate the transmission screw 424, which drives the threaded slider 425 to slide in the sliding groove 422, thereby changing the position of the connecting slide column 43 and achieving the purpose of adjusting the swing amplitude of the swing arm 3. In case of emergency during the detection process, the emergency stop switch 75 can be pressed to stop the equipment immediately. After the detection is completed, the counter reset button 72 is pressed to reset the counter 71 to zero, so that the next detection can be performed.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
