Description

Technical Field

[0001] This utility model relates to the field of packaging film puncture technology, specifically to a food packaging film puncture detection device. Background Technology

[0002] Food packaging film is a polymer material used to wrap the surface of food, primarily to isolate microorganisms, bacteria, and external contaminants, preventing and prolonging food spoilage. In daily life, industrially produced paper instant noodle containers typically require packaging film for wrapping. The film's barrier properties ensure the food quality within the container. However, the film also needs a certain level of impact resistance; otherwise, easily damaged film cannot adequately protect the noodles. Therefore, companies must conduct sampling puncture tests on the packaging film before use. Existing puncture testing devices require manual cutting, removal, and positioning of the film before puncture testing can be performed. This cumbersome process increases the workload for operators and reduces testing efficiency. Utility Model Content

[0003] To address the shortcomings of existing packaging film puncture inspection devices, which involve cumbersome inspection steps, high labor intensity for operators, and reduced inspection efficiency, this utility model provides a food packaging film puncture inspection device with simpler inspection steps, lower labor intensity for operators, and increased inspection efficiency for punctured packaging films.

[0004] This utility model provides the following technical solution:

[0005] It includes a testing platform, with a positioning seat installed on the end face of the testing platform. Positioning columns are arranged in a triangular shape around the positioning seat. A constant pressure puncture structure is provided above the positioning seat. The constant pressure puncture structure includes a main frame, which includes a first main board and a second main board connected by fixing columns. Below the second main board, a pad, a cutting ring, a locking block, and a constant pressure column are respectively provided. The cutting ring is installed on the pad. The locking block and the constant pressure column are arranged in a triangular shape around the pad, with a slot on the side of the constant pressure column. A locking column is installed in the slot, and the locking block can engage with the constant pressure column through the locking column. The pad and the locking block are both installed at the bottom of the second main board. A membrane-penetrating needle is installed at the bottom of the constant pressure column. A telescopic cylinder is provided between the first and second main boards. The piston rod of the telescopic cylinder extends downward through the second main board, and a signal transmitter is installed at its extended end. A puncture detection head is installed at the bottom of the signal transmitter.

[0006] Its further features are:

[0007] The top end of the positioning seat is provided with an annular groove to match the cutting blade ring, and a central circular groove is provided at the center of its top. The central circular groove is used to insert the puncture detection head. The positioning post is provided with a circular hole to match the membrane needle.

[0008] A movable block is provided above the first main board. A rotator is installed at the end of the movable block. The rotating shaft of the rotator passes through the movable block and is fixedly connected to the first main board. A counterweight is installed at the tail end of the movable block and is fitted together with the counterweight onto a lead screw. The lead screw is installed inside a fixed base. A drive device is provided inside the detection table to match the lead screw.

[0009] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0010] The constant pressure puncture structure features a film-piercing needle that works in conjunction with a positioning post to apply constant pressure to the packaging film during cutting. The constant pressure post is engaged with a locking block, allowing the main frame to drive the cutting blade ring to continue cutting the packaging film after the constant pressure is applied. The padding block provides edge clamping detection and positioning for the cut packaging film. The puncture detection head can directly pierce the film to test its impact resistance, achieving automatic positioning, clamping, cutting, and automatic clamping and positioning detection. The detection steps are relatively simple, reducing the workload for operators and increasing the efficiency of puncture detection of packaging films. Attached Figure Description

The constant pressure puncture structure includes a main frame 9. Figure 4 The main frame 9 includes a first main board 10 and a second main board 21 connected by fixing posts. Both the first main board 10 and the second main board 21 are designed in a triangular shape. Below the second main board 21, there are respectively a pad 12, a cutting blade ring 13, a locking block 14, and a pressure-regulating post 15. The cutting blade ring 13 is installed on the pad 12. The locking block 14 and the pressure-regulating post 15 are arranged in a triangular shape around the pad 12 with the pad 12 as the center. The pressure-regulating post 15 has a slot on its side, and a locking post 16 is installed in the slot. The locking block 14 can be engaged with the pressure-regulating post 15 through the locking post 16. The pad 12 and the locking block 14 are installed at the bottom of the second main board 21. A membrane-penetrating needle 17 is installed at the bottom of the pressure-regulating post 15. Figure 6 A telescopic cylinder 11 is provided between the first main board 10 and the second main board 21. The piston rod of the telescopic cylinder 11 extends downward through the second main board 21, and a signal transmitter 19 is installed at the end of its extended end. A puncture detection head 18 is installed at the bottom of the signal transmitter 19.

[0021] See Figure 3 The top end of the positioning seat 3 is provided with an annular groove to match the cutting blade ring 13, and a central circular groove is provided at the center of its top. The central circular groove is used to insert the puncture detection head 18. The positioning post 4 is provided with a circular hole to match the membrane needle 17.

[0024] Working principle of this utility model:

[0025] When using this invention, firstly, the packaging film is laid flat on the positioning seat 3, its size needing to cover the top end face of the positioning post 4. Then, the drive device is activated, causing the moving block 6 to move downwards. The main frame 9 moves synchronously with the moving block, and the triangularly arranged film-piercing needles 17 will pierce through the packaging film until the pressure post 15 contacts the positioning post 4. At this point, the packaging film is in a compressed state. Then, the rotator 8 is activated, the main frame 9 rotates, and the locking block 14 disengages from the pressure post 15. Subsequently, the main frame 9 can continue to move downwards, and the cutting blade ring 13 pushes the packaging film into... The packaging film is cut into a circle and pressed down by the pad 12. Then, the telescopic cylinder 11 is activated, and the signal transmitter 19 and the puncture detection head 18 move downwards synchronously. The puncture detection head 18 penetrates the packaging film, detects the impact resistance data, and transmits it to the touch screen controller 20 by the signal transmitter 19. Then, the main frame 9 retracts and rotates to engage with the pressure column 15 before resetting together. It can perform positioning and circular cutting of the packaging film without manual operation. The detection steps are relatively simple, reducing the labor intensity of the operator and increasing the detection efficiency of puncture packaging film.
