Description

Technical Field

[0001] This utility model belongs to the field of plastic wrap testing technology, specifically referring to a puncture detection device for plastic wrap processing. Background Technology

[0002] Puncture testing in plastic wrap processing is a quality inspection method used to evaluate the physical properties of plastic wrap (especially its puncture resistance). It is mainly used to determine the ability of plastic wrap to resist puncture by sharp objects in actual use, and to ensure its reliability in packaging, storage and other scenarios.

[0003] In existing technologies, when performing puncture tests on films, it is common to manually apply pressure to the plastic wrap vertically with a sharp object at a slow and uniform speed, and observe whether the sample is punctured or cracked. The operation is very convenient, but it has a drawback: manual puncture has low accuracy and cannot accurately determine the force value when the film is punctured. Therefore, improvements are needed. Utility Model Content

[0004] The technical problem this invention aims to solve is that in the prior art, manually puncturing plastic wrap results in low precision and the force applied when the film is punctured cannot be determined.

[0005] To solve the above problems, the technical solution adopted by this utility model is as follows: a puncture detection device for processing plastic wrap includes a detection frame, the upper end of the detection frame is grooved and two sets of slide seats are slidably arranged in the groove, the detection frame is provided with a tension driving device that can adjust the left and right spacing of the slide seats, the slide seats are provided with a pressing and fixing device to press and fix the plastic wrap, and the top of the detection frame is provided with an adjustable detection device.

[0006] Furthermore, the adjustable detection device includes a support frame, which is arranged in an inverted L-shape and fixed to the top surface of the detection platform. An electric push rod is vertically fixed downward on the support frame, with its output end penetrating through the top wall of the detection platform. An electromagnet is fixed to the lower end of the electric push rod, and a detection cone is magnetically attracted to the lower end of the electromagnet. When the electromagnet is de-energized, the detection cone can move freely downward, and the detection cone can perform a puncture test on the plastic wrap below. The electric push rod can adjust the height of the detection cone, so that the impact force value when the plastic wrap is punctured can be calculated based on the distance between the detection cone and the film.

[0007] Furthermore, the pressing and fixing device includes a fixing frame, which is fixed to the top of the slide. The fixing frame is vertically fixed downward to an electric push rod two, the output end of which passes through the top of the slide. The output end of the electric push rod two is connected to a pressure plate. The upper end of the pressure plate is symmetrically provided with two sets of guide rods for the electric push rod two, which pass upward through the slide. The contact surface between the pressure plate and the slide is provided with anti-slip rubber. The pressure plate can flatten and press the plastic wrap onto the slide.

[0008] Furthermore, the stretching drive device includes a motor, which is fixed to the side wall of the testing platform. The output end of the motor is connected to a lead screw and threadedly connected to a slide block. The lead screw is arranged in two sections and can satisfy the sliding of the slide blocks on both sides in the slide groove. By sliding the slide blocks, the plastic wrap can be stretched flat, which is more conducive to puncture detection.

[0009] Furthermore, a scale is provided on the output end of the electric push rod, and a pointer is provided on the testing platform pointing to the scale. The precise height of the testing cone can be determined by extending and retracting the electric push rod.

[0010] Furthermore, the testing platform is equipped with an operation panel, which is electrically connected to the electromagnet and the motor, and is also electrically connected to electric push rod one and electric push rod two.

[0011] The beneficial effects achieved by adopting the above-described structure are as follows:

[0012] 1. This utility model, by setting an adjustable detection device, allows the electric push rod to adjust the falling height of the detection cone, thereby adjusting the piercing force of the detection cone on the plastic wrap until it is pierced. The scale can accurately determine the height of the detection cone to the film.

[0013] 2. This utility model uses a pressing and fixing device to place the plastic wrap between the slides and flatten it. The pressure plate is pushed down by the electric push rod, which can press and fix the plastic wrap. At the same time, by starting the motor, the lead screw drives the slides to slide in opposite directions, which can tighten the pressed plastic wrap to facilitate puncture experiments.

Detailed Implementation

[0019] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0021] like Figure 1-4 This utility model discloses a puncture detection device for processing plastic wrap, including a detection stand 1. The upper end of the detection stand 1 is grooved and two sets of slide seats 2 are slidably arranged in the groove. The detection stand 1 is provided with a tension driving device 3, which can adjust the left and right distance of the slide seats 2. The slide seats 2 are provided with a pressing and fixing device 4 to press and fix the plastic wrap. The top of the detection stand 1 is provided with an adjustable detection device 5.

[0022] like Figure 1-3The adjustable detection device 5 includes a bracket 6, which is arranged in an inverted L shape and fixed to the top surface of the detection platform 1. An electric push rod 7 is vertically fixed to the bracket 6 and its output end passes through the top wall of the detection platform 1. A scale 16 is provided on the output end of the electric push rod 7. A pointer 17 is provided on the detection platform 1 and points to the scale 16. By extending and retracting the electric push rod 7, the precise height of the detection cone 9 can be determined. An electromagnet 8 is fixed to the lower end of the electric push rod 7. The lower end of the electromagnet 8 magnetically attracts the detection cone 9. When the electromagnet 8 is de-energized, the detection cone 9 can move freely downward. The detection cone 9 can perform a puncture test on the plastic wrap below. The electric push rod 7 can adjust the height of the detection cone 9. Based on the distance between the detection cone 9 and the film, the impact force value when the plastic wrap is punctured can be calculated.

[0023] like Figure 1-4 The pressing and fixing device 4 includes a fixing frame 10, which is fixed to the top of the slide 2. The fixing frame 10 is vertically fixed to an electric push rod 11 with its output end penetrating the top of the slide 2. The output end of the electric push rod 11 is connected to a pressure plate 12. The upper end of the pressure plate 12 is symmetrically provided with two sets of guide rods 13 for the electric push rod 11, which penetrate upward through the slide 2. The contact surface between the pressure plate 12 and the slide 2 is provided with anti-slip rubber. The pressure plate 12 can flatten and press the plastic wrap onto the slide 2.

[0024] like Figure 1-3 The stretching drive device 3 includes a motor 14, which is fixed to the side wall of the testing platform 1. The testing platform 1 is equipped with an operation panel 18, which is electrically connected to the electromagnet 8 and the motor 14. The operation panel 18 is also electrically connected to the electric push rod 7 and the electric push rod 11. The output end of the motor 14 is connected to a lead screw 15 and threadedly connected to the slide block 2. The lead screw 15 is arranged in two sections and can satisfy the sliding blocks 2 on both sides to slide towards each other in the slide groove. By sliding the slide blocks 2, the plastic wrap can be pulled flat, which is more conducive to puncture detection.

[0025] In practical use, before conducting a puncture test on the plastic wrap, first lay the plastic wrap flat in the corresponding groove between the slide blocks 2. Then, control the electric push rod 11 to start via the operation panel 18, causing the pressure plate 12 to move down. At the same time, the guide rod 13 slides in the slide block 2 until the pressure plate 12 presses and fixes the plastic wrap. Then, by starting the motor 14, the lead screw 15 drives the slide block 2 to slide relative to each other in the groove, which can tighten the plastic wrap into a horizontal state.

[0026] The electromagnet 8 is de-energized by controlling the control panel 18, and the detection cone 9 loses its attractive force and falls freely until it punctures the plastic wrap below. If the plastic wrap is not punctured, the height of the electromagnet 8 is adjusted. By controlling the electric push rod 7, the electromagnet 8 is pulled upward. The height of the detection cone 9 can be seen by the pointer 17 pointing to the scale 16. Each adjustment can be made in a small increment until the detection cone 9 completes the puncture of the plastic wrap. The impact force when the detection cone 9 falls to the detection cone 9 can be calculated by the height of the detection cone 9, thus accurately calculating the force value when the plastic wrap is punctured.

[0027] It should be noted that a power supply is located behind the control panel 18, and is connected to the electric push rod 7, the electric push rod 11, the motor 14 and the electromagnet 8 via wiring. The operation and shutdown are fully controlled through the control panel 18. This is existing technology and will not be described in detail here.

[0028] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
