Description

Technical Field

[0001] The utility model belongs to the technical field of packaging material testing equipment, in particular to a multi-station packaging material moisture permeability testing device. Background Art

[0002] With the rapid development of China's economy and the improvement of people's quality of life, the demand for convenience foods such as microwave foods, snack foods and frozen foods will continue to increase, which will directly drive the demand for related food packaging. Packaging materials refer to the materials used to manufacture packaging containers, packaging decoration, packaging printing, packaging transportation, etc. to meet product packaging requirements. It includes main packaging materials such as metal, plastic, glass, ceramics, paper, bamboo, wild mushrooms, natural fibers, chemical fibers, composite materials, and auxiliary materials such as strapping, decoration, and printing materials.

[0003] Chinese patent publication number CN113588429A discloses a packaging material production test. The patent first uses a vertical cylinder in a vertical telescopic adjustment assembly to adjust the height of a horizontal fixed plate to suit different testing requirements, depending on the sample of packaging material to be tested. The vertical cylinder drives a positioning screw, thereby adjusting the height of the horizontal fixed plate to meet different testing requirements. During the tensile test, the two ends of the packaging material are fixed to a dynamic fixed block and a fixed fixed block, respectively. The dynamic fixed block is mounted on a dynamic connecting plate, and the fixed fixed block is mounted on a fixed connecting plate. The tensile cylinder is activated, driving the dynamic connecting plate to move via a connecting column, thereby applying a tensile force to the packaging material. The dynamic fixed block retaining grooves on the dynamic fixed block and the fixed fixed block retaining grooves on the fixed fixed block help to better secure the packaging material. However, this device cannot test the transparency of the packaging material. For food, suitable moisture-permeable packaging can prevent excessive moisture loss or absorption, maintain the taste, texture, and freshness of the food, and extend the shelf life. For pharmaceuticals, it can ensure that the drug ingredients are not deteriorated by humidity, ensuring the efficacy of the drug.

[0004] In view of this, the present utility model is proposed. Utility Model Content

DETAILED DESCRIPTION

[0027] The present invention will now be described in further detail with reference to the accompanying drawings.

[0028] See also Figure 1-4As shown, in this embodiment, a multi-station packaging material moisture permeability test device is provided, including a box body 1, a detection table 2 is connected to the top of the box body 1, a fixing table 4 is connected to the side wall of the box body 1, and a humidity detector 3 and a control panel 5 are installed on the fixing table 4. The humidity detector 3 is used to obtain relevant humidity data, and the control panel 5 is used to control the operating parameters and operation process of the test device. A fixing block 6 is located on the top surface of the detection table 2, and a screw rod 8 is connected to the top of the fixing block 6, and a fixing plate 7 is connected to the bottom of the screw 8. Through the screw 8 passing through the top of the fixing block 6 and the fixing plate 7 connected to the bottom of the screw 8, the fixing block 6 can be The packaging materials placed on the testing table 2 are fixed, and the transmission mechanism is located at the bottom end of the testing table 2. The transmission mechanism includes a second rotating shaft 13, which is fixedly installed at the center of the bottom end of the testing table 2. The bottom end of the second rotating shaft 13 is connected to the motor 9, and the middle end surface of the second rotating shaft 13 is sleeved with a first gear 10. The bottom end of the testing table 2 is connected to the first rotating shaft 12, and the surface of the first rotating shaft 12 is sequentially connected to the rotating member 15 and the second gear 11. A transmission block 14 is installed at the bottom end of the testing table 2. The transmission mechanism can realize intermittent rotation of the testing table 2, thereby facilitating the detection of multiple packaging materials.

[0029] In this embodiment, a slider 16 is installed on the surface of the testing platform 2, and a corresponding slide groove is opened on the top of the inner wall of the box body 1. The testing platform 2 is rotatably connected to the box body 1 through the slider 16 and the slide groove. The testing platform 2 can be rotated through the slide groove to move the packaging material to the humidity detector 3 to realize the moisture permeability detection of the packaging material.

[0030] For example, when it is necessary to inspect packaging materials at different stations, the inspection platform 2 can be rotated smoothly and accurately through this rotation connection, and each fixed block 6 can be aligned with the humidity detector 3 in turn to ensure the smooth progress of the inspection process.

[0031] There are four fixed blocks 6, which are evenly distributed with the center of the detection platform 2 as the polar axis, so that the humidity detector 3 can detect multiple packaging materials and improve the detection efficiency. There are four transmission blocks 14, which are respectively located under the four fixed blocks 6. The detection platform 2 can be rotated intermittently by 90 degrees through the transmission blocks 14. The transmission blocks 14 are located under the fixed blocks 6 to ensure that the detection platform 2 accurately aligns the fixed blocks 6 with the humidity detector 3 when rotating. The side walls of the transmission blocks 14 are arc-shaped, and the first rotating shaft 12 passes through the middle end of the rotating member 15, and the rotating member 15 is fixedly connected to the first rotating shaft 12. The moving member 15 can move synchronously with the rotation of the first rotating shaft 12. The left side of the rotating member 15 is fan-shaped, and the fan-shaped side wall is located at the arc side wall of the transmission block 14. The length of the right side of the transmission member is longer than the fan-shaped length of the left side. When the rotating member 15 rotates, the left side does not contact the transmission block 14, and the right side will resist the transmission block 14 and drive the detection platform 2 to move. The first transmission shaft is located on the side of the second transmission shaft, and a connecting block is connected between them. The first gear 10 and the second gear 11 are located on the same horizontal line and are meshed with each other. The rotation of the first gear 10 can drive the second gear 11 to rotate.

[0032] The second rotating shaft 13 rotates by the motor 9, and at the same time drives the first gear 10 to rotate. The rotation of the first gear 10 drives the second gear 11 to rotate, and then drives the first rotating shaft 12 to rotate. At this time, the rotating member 15 also rotates. When the left fan-shaped end of the rotating member 15 passes the transmission block 14, the fan-shaped end will move along the arc-shaped inner wall of the transmission block 14 without contacting the transmission block 14. After the left fan-shaped end of the rotating member 15 passes the transmission block 14, the right end will rest against the side wall of the transmission block 14, thereby driving the detection table 2 to rotate, causing the detection table 2 to rotate 90°. The right end of the rotating member 15 will disengage from the side wall of the transmission block 14 after rotating half a circle. At this time, the detection table 2 stops rotating, thereby realizing intermittent rotation of the detection table 2.

[0033] Working principle:

[0034] After starting the motor 9, the motor 9 drives the second rotating shaft 13 to rotate. Since the middle end of the second rotating shaft 13 is sleeved with the first gear 10, the rotation of the second rotating shaft 13 will drive the first gear 10 to rotate. The first gear 10 and the second gear 11 are located on the same horizontal line and meshed with each other, so the rotation of the first gear 10 will drive the second gear 11 to rotate, and then drive the first rotating shaft 12 to rotate. When the first rotating shaft 12 rotates, the rotating member 15 fixedly connected to it and passing through the middle end will also rotate synchronously. When the fan-shaped end on the left side of the rotating member 15 passes the transmission block 14, the fan-shaped end will move along the arc of the transmission block 14. shaped inner wall moves, at this time the sector-shaped end is not in contact with the transmission block 14, when the sector-shaped end on the left side of the rotating member 15 passes the transmission block 14, the right end of the rotating member 15 will abut the side wall of the transmission block 14, thereby driving the entire detection platform 2 to rotate, due to the setting of the transmission block 14, the detection platform 2 rotates 90° each time, when the right end of the rotating member 15 is separated from the side wall of the transmission block 14 after rotating half a circle, the detection platform 2 stops rotating, thereby realizing the intermittent rotation of the detection platform 2, and the humidity sensor is provided with detection time when the detection platform 2 stops rotating;

[0035] A slider 16 is mounted on the surface of the testing platform 2, and a corresponding slide groove is provided at the top of the inner wall of the box 1. This structure allows the testing platform 2 to rotate smoothly and accurately within the box 1. The fixed block 6 connected to the testing platform 2 is used to fix the packaging materials. The four transmission blocks 14 located below the fixed block 6 ensure that the fixed block 6 can be accurately aligned with the humidity detector 3 when the testing platform 2 rotates, so that the humidity detector 3 can perform moisture permeability tests on multiple packaging materials in sequence, thereby improving detection efficiency.

[0036] For example, in actual testing, after the packaging material on the first fixed block 6 is tested, the testing platform 2 is intermittently rotated 90° so that the packaging material on the second fixed block 6 reaches the testing position, and so on, to achieve orderly testing of packaging materials at multiple stations.

Any technical solution that is the same or similar to the present invention falls within the scope of protection of the present invention.
