Abstract
Description
Technical Field
[0001] The utility model relates to the field of electronic product accessories, in particular to a composite strength detection tool between packaging material layers. Background Art
[0002] Many materials (such as composite films) are composed of layers (also known as film materials) composited together. In order to detect the composite strength between layers, the current method for detecting the composite strength between layers of such composite materials is to first cut the substrate into small strips of specified width, manually peel them off, and then place the separated two ends of the substrate on an electronic tensile testing machine respectively. The corresponding curve and value are detected by the electronic tensile testing machine at room temperature. However, the composite strength between layers of the material is also highly correlated with temperature. Simply relying on electronic tensile testing machines cannot effectively detect the composite strength between layers of the material under different temperature conditions. Utility Model Content
[0003] In view of the above problems, the utility model proposes a composite strength detection tool between packaging material layers.
[0004] The technical solution adopted by the utility model is as follows:
[0005] A composite strength testing tool between packaging material layers, comprising a box body, a box door, an electric heating tube, a temperature detection probe, a hanging rod, a bottom plate, a clamp and a suspension block, wherein one end of the box door is rotatably matched with the box body, and one end of the box door is detachably matched with the box body, the electric heating tube and the temperature detection probe are both arranged in the box body, and the electric heating tube is located at the bottom of the box body, and the temperature detection probe is located at the top of the box body, the hanging rod is arranged in the box body, the bottom plate is hung on the hanging rod, the clamp is arranged on the bottom plate, the clamp is used to clamp a diaphragm, the suspension block is used to contact the diaphragm, and the bottom plate is provided with a scale.
[0006] The method of using this detection tool is as follows. First, the box body, box door, electric heating tube and temperature detection probe form an oven (in fact, this detection tool is also modified based on the oven). A suspension rod is set inside the oven. The suspension rod is a cylindrical suspension rod. The bottom plate is hung on the suspension rod, and the bottom plate is roughly vertical relative to the suspension rod. Assuming that the composite strength between the aluminum film and the PET film is to be measured, firstly, a distance is torn apart between the PET film and the aluminum film at one end of the entire composite material, and then the exposed end of the aluminum film is clamped on the clamp, the entire aluminum film is in a state of being flush and close to the bottom plate, and the aluminum film and the PET film are in a state of being parallel to the scale, and then a suspension block is hung on the end of the PET film that is not bonded to the aluminum film. The suspension block has a tendency to pull the PET film downward. Since the weight of the suspension block does not change, it can be approximately regarded as that the downward pulling force of the suspension block on the PET film is constant. The tendency of the suspension block to pull the PET film downward can cause the PET film and the aluminum film to be torn apart. Since a scale is set on the bottom plate, the distance value (assuming M) that the PET film and the aluminum film are pulled apart can be determined by comparing the bonding position line between the PET film and the aluminum film. The separation speed of the PET film and the aluminum film per unit time at the temperature can be calculated through the distance value and the tearing time (assuming N), so that the composite strength of the aluminum film and the PET film can be obtained visually. When you need to test different strengths, you only need to use suspension blocks of different masses (such as replacing 100g with 150g). If you need to test the strength under different temperature conditions, you only need to adjust the heating power of the electric heating tube.
[0007] Compared with electronic measuring equipment such as electronic dynamometers, this type of measuring equipment uses mechanical structures such as a scale with a scale base and a horizontal heavy suspension block for measurement. The structure is simple and reliable, and the entire measuring process is basically not affected by temperature. The measurement results are more reliable because the electrical components in the electronic dynamometer may be inaccurate when measured at high temperatures (such as temperatures above 80°C).
[0008] In summary, this kind of testing tool can measure the composite strength between films at different temperatures and with different tensile forces. The testing structure is simple and the measuring results are reliable.
[0009] Optionally, a curved hook is provided on the suspension block.
[0010] The specific suspension block is hung on the PET film through its own curved hook.
[0011] Optionally, a hook is provided on the bottom plate, and the hook is used to cooperate with the suspension rod.
[0012] The specific hook is in an arc shape, and the arc-shaped hook is hung on a hanging rod, and the hanging rod is a cylindrical hanging rod, and the two ends of the hanging rod are respectively fixed to the two side walls of the box body.
[0013] Optionally, there are multiple temperature detection probes, and the temperature detection probes are located at different positions on the top of the box.
[0014] The purpose of setting up multiple temperature detection probes is to more accurately detect the temperature inside the box, and the heating power of the electric heating tube is adjusted according to the data measured by the temperature detection probes.
[0015] Similarly, without affecting the detection, temperature detection probes can also be installed at other locations inside the box (such as the inner wall of the box).
[0016] Optionally, there are multiple electric heating tubes, and the electric heating tubes are arranged at the bottom of the box.
[0017] Optionally, a glass observation window is provided on the box door.
[0018] The purpose of setting a transparent glass observation window is to facilitate observation of the conditions inside the box.
[0019] Optionally, the suspension block is a cylindrical suspension block.
[0020] Optionally, the clip is a dovetail clip.
[0021] Specifically, in order to ensure that the aluminum film can be closely attached to and flush with the bottom plate, a sink groove can be opened on the bottom plate, and a part of the clip is located in the sink groove, so that the aluminum film can be flush with the bottom plate.
[0022] Because this tool may need to be tested at a test temperature of 120 degrees Celsius or even 150 degrees Celsius, in order to avoid thermal expansion and contraction of the suspension block and the base plate, this tool can use a metal aluminum plate as the base plate, and the suspension block can use a stainless steel hook weight (this weight comes with a suspension hook).
[0023] The beneficial effects of the utility model are as follows: the detection tool can measure the composite strength between films at different temperatures and with different pulling forces, the detection structure is simple, and the measurement result is reliable.

[0029] The utility model is described in detail below in conjunction with the accompanying drawings.
[0030] As attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 And attached Figure 4 As shown, a composite strength testing tool between packaging material layers includes a box body 2, a box door 9, an electric heating tube 3, a temperature detection probe 1, a suspension rod 4, a bottom plate 5, a clip 6 and a suspension block 8. One end of the box door 9 is rotatably matched with the box body 2 through a hinge, and one end of the box door 9 is detachably matched with the box body 2 through a locking rod 11. The electric heating tube 3 and the temperature detection probe 1 are both arranged in the box body 2, and the electric heating tube 3 is located at the bottom of the box body 2, and the temperature detection probe 1 is located at the top of the box body 2. The suspension rod 4 is arranged in the box body 2, the bottom plate 5 is hung on the suspension rod 4, the clip 6 is arranged on the bottom plate 5, the clip 6 is used to clamp the diaphragm, the suspension block 8 is used to contact the diaphragm, and the bottom plate 5 is provided with a scale.
[0031] The method of using this detection tool is as follows. First, the box body 2, the box door 9, the electric heating tube 3 and the temperature detection probe 1 form an oven (in fact, this detection tool is also modified based on the oven). A suspension rod 4 is arranged inside the oven. The suspension rod 4 is a cylindrical suspension rod 4. The bottom plate 5 is hung on the suspension rod, and the bottom plate 5 is roughly vertical relative to the suspension rod. Assuming that the composite strength between the aluminum film 701 and the PET film 702 is to be measured, firstly, a distance is torn between the PET film 702 and the aluminum film 701 at one end of the entire composite material, and then the exposed end of the aluminum film 701 is clamped on the clamp 6, the entire aluminum film 701 is in a state of being flush and close to the bottom plate 5, and the aluminum film 701 and the PET film 702 are in a state of being parallel to the scale, and then the suspension block 8 is hung on the end of the PET film 702 that is not bonded to the aluminum film 701, and the suspension block 8 has a tendency to pull the PET film 702 downward. Since the weight of the suspension block 8 does not change, it can be approximately regarded as that the downward pulling force of the suspension block 8 on the PET film 702 is constant, and the tendency of the suspension block 8 to pull the PET film 702 downward can cause the PET film 702 and the aluminum film 701 to be torn apart (the suspension block 8 is pulled downward). The PET film 702 is in frictional contact. Since the friction coefficient between the PET film 702 and the suspension block 8 is very small, the friction force between the PET film 702 and the suspension block 8 can be ignored). Since a scale is set on the bottom plate 5, by comparing the bonding position line 712 between the PET film 702 and the aluminum film 701 (the bonding position line 712 is initially located at the dotted line C, and after a period of time, the bonding position line 712 is located at the dotted line D), the distance value of the PET film 702 and the aluminum film 701 being pulled apart can be determined (assuming it is M, which is the distance value between the dotted line C and the dotted line D). The separation speed of the PET film 702 and the aluminum film 701 per unit time at the temperature can be calculated through the distance value and the tearing time (assuming it is N), so that the composite strength of the aluminum film 701 and the PET film 702 can be visually obtained. When different strengths need to be tested, it is only necessary to use a suspension block 8 of different mass (such as replacing 100g with 150g). When the strength under different temperature conditions needs to be tested, it is only necessary to adjust the heating power of the electric heating tube 3.
[0032] Compared with electronic measuring equipment such as electronic dynamometers, this type of measuring equipment uses mechanical structures such as a scale with a scale base plate 5 and a horizontal heavy suspension block 8 for measurement. The structure is simple and reliable, and the entire measuring process is basically not affected by temperature. The measurement result is more reliable because the electrical components in the electronic dynamometer may be inaccurate when measured at high temperatures (such as temperatures above 80°C).
[0033] In summary, this kind of testing tool can measure the composite strength between films at different temperatures and with different tensile forces. The testing structure is simple and the measuring results are reliable.
[0034] As attached Figure 1, Attachment Figure 2 , Attachment Figure 3 And attached Figure 4 As shown, the suspension block 8 is provided with an arc hook.
[0035] Specifically, the suspension block 8 is hung on the PET film 702 through its own curved hook.
[0036] As attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 And attached Figure 4 As shown, a hook 501 is provided on the bottom plate 5 , and the hook 501 is used to cooperate with the suspension rod 4 .
[0037] Specifically, the hook 501 is in an arc shape, and the arc-shaped hook 501 is hung on the hanging rod 4 , and the hanging rod 4 is a cylindrical hanging rod 4 , and the two ends of the hanging rod 4 are respectively fixed to the two side walls of the box body 2 .
[0038] As attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 And attached Figure 4 As shown, there are multiple temperature detection probes 1, and the temperature detection probes 1 are located at different positions on the top of the box.
[0039] The purpose of providing a plurality of temperature detection probes 1 is to more accurately detect the temperature in the box body 2 , and to adjust the heating power of the electric heating tube 3 according to the data measured by the temperature detection probes 1 .
[0040] Similarly, without affecting the detection, the temperature detection probe 1 can also be installed at other positions inside the box 2 (such as the inner wall of the box 2).
[0041] As attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 And attached Figure 4 As shown, there are multiple electric heating tubes 3, and the electric heating tubes 3 are arranged at the bottom of the box body 2.
[0042] As attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 And attached Figure 4 As shown, a glass observation window 10 is provided on the box door 9.
[0043] The transparent glass observation window 10 is provided to facilitate observation of the conditions inside the box body 2 .
[0044] As attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 And attached Figure 4 As shown, the suspension block 8 is a cylindrical suspension block 8 .
[0045] As attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 And attached Figure 4 As shown, the clip 6 is a dovetail clip.
[0046] Specifically, in order to ensure that the aluminum film 701 can be closely attached to and flush with the bottom plate 5 , a recess 502 can be provided on the bottom plate 5 , and a portion of the clip 6 is located in the recess 502 , so that the aluminum film 701 can be flush with the bottom plate 5 .
[0047] Because this tool may need to be tested at a test temperature of 120 degrees Celsius or even 150 degrees Celsius, in order to avoid thermal expansion and contraction of the suspension block 8 and the base plate 5, this tool can use a metal aluminum plate as the base plate 5, and the suspension block 8 can use a stainless steel weight with a hook (this weight comes with a suspension hook).
[0048] In this tooling, the box body 2, the electric heating tube 3 and the box door 9 actually form a point oven, so this device can actually directly use the DP brand Y101A-1 electric heating oven (the general structure is similar to the attached Figure 4 Similarly) the modification is performed by adding a suspension rod 4.
[0049] It should be specially noted that this tool uses the composite film of aluminum film 701 and PET film 702 as an example to illustrate the working process of this tool, which does not mean that this tool can only detect the composite film of PET film 702 and aluminum film 701. Other similar double-layer composite films can also be detected by this tool.
