Description

Technical Field

[0001] This invention relates to the field of paper film testing technology, specifically to a testing device and method for decorative paper raw film. Background Technology

[0002] Decorative paper film is widely used in decorative materials such as furniture and flooring, and its heat shrinkage rate is one of the key indicators for measuring product quality. During production, the film needs to undergo heat treatment to test its dimensional stability under high-temperature conditions. Traditional testing methods typically rely on manual operation, such as manually immersing the film sample in a hot water bath and then measuring the shrinkage change. This method is inefficient in industrial batch testing and is easily affected by human factors, leading to poor consistency in results.

[0003] In existing technologies, decorative paper film testing equipment mostly employs simple immersion heating devices, such as constant temperature water baths. However, the sample fixation method is rudimentary, and heating uniformity is difficult to guarantee. Based on the analysis of traditional methods, existing technologies mainly suffer from the following drawbacks:

[0004] First, existing equipment often requires manual placement and removal of samples, making batch testing impossible; for example, it can only process a single sample at a time, resulting in long testing cycles and making it difficult to meet the quality control requirements of large-scale production lines.

[0005] Secondly, in traditional water bath heating equipment, the sample is not firmly fixed and is prone to shaking or tilting, resulting in uneven heating. Although constant temperature water bath can provide a stable temperature, the existing technology does not integrate an effective sample fixing mechanism, which affects the accuracy of shrinkage measurement.

[0006] Third, the sample needs to be completely immersed in hot water during the heating process, but the sample box of the existing equipment is often not sealed tightly, and hot water can easily seep in or leak from the bottom, causing contamination of the original membrane or test errors.

[0007] Fourth, existing equipment relies on manual opening and closing of the pot lid and adjustment of the sample position, which increases the complexity of operation and is prone to human error. Existing technologies mostly use manual operation and lack an integrated drive system, resulting in a discontinuous detection process.

[0008] In view of this, the present invention proposes a device and method for detecting decorative paper original film. Summary of the Invention

[0021] Step 2: Drive the two pot lids to slide back and forth through the adjustment mechanism to open the pot lids, and then control the electric push rod to drive the mounting bracket downwards, so that the oil injection pipe can drive the detection seat into the constant temperature water bath.

[0025] The working principle and beneficial effects of this invention are as follows:

[0026] 1. The testing facility is equipped with multiple sample boxes arranged in a circular array, which can hold multiple original membrane samples at the same time.

The hydraulic seal is reliable, completely preventing hot water leakage, ensuring a clean testing environment, and integrating automatic sealing and unlocking to reduce manual operation.

[0029] 4. The adjustment mechanism automatically controls the sliding of the pot lid towards or away from each other by driving the gear and rack through the second motor; the driving component and the oil supply component are linked, the first motor drives the transmission gear and cam at the same time, the cam pushes the rotating plate and the slider, so that the second piston in the oil cylinder supplies oil, realizing the locking and sealing synchronously; the whole process is automated (such as pot lid opening and closing, sample lifting and lowering, oil pressure control) to reduce human interference and improve the repeatability of the test.

[0043] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0044] like Figures 1 to 11 As shown, this embodiment proposes a decorative paper film testing device, including a constant temperature water bath 1. Slide rails 2 are fixedly connected to both ends of the top of the constant temperature water bath 1, and lids 3 are slidably connected to both ends of the slide rails 2. An adjustment mechanism 4 is provided at one end of the outer side of the constant temperature water bath 1 to drive the two lids 3 to slide towards or away from each other.

The testing mechanism 8 includes an oil injection pipe 81 fixedly connected to the bottom of the mounting frame 7. The bottom of the oil injection pipe 81 is fixedly connected to... A detection seat 82 is connected, and a number of sample boxes 83 arranged in a circular array along the outer edge of the detection seat 82 for placing decorative paper film are provided. A sleeve 84 is rotatably connected to the outer side of the oil injection pipe 81. A locking component 85 for fixing the sample box 83 is provided at the bottom end of the oil injection pipe 81. A sealing component 86 for sealing the bottom of the sample box 83 by injecting oil is provided at the bottom of the oil injection pipe 81.

An oil supply component 88 for introducing oil into the oil injection pipe 81 by cooperating with the activation of the driving component 87 is provided at the top of the oil injection pipe 81.

[0045] In this embodiment, when the device is working, the decorative paper film is first placed in the sample box 83. The lid 3 is opened by the adjustment mechanism 4, and the electric push rod 6 drives the mounting bracket 7 to descend, so that the detection seat 82 is immersed in the hot water of the constant temperature water bath 1. The constant temperature water bath 1 heats the water, and the hot water comes into contact with the film through the mesh of the sample box 83 to achieve heating. After heating is completed, the electric push rod 6 lifts the detection seat 82, and the sample is taken out to measure the shrinkage rate. This device realizes automated detection. The constant temperature water bath 1 provides a stable heating environment to ensure detection accuracy. The multi-component collaborative work of the detection mechanism 8 improves efficiency and is suitable for batch sample testing.

[0046] In a further preferred embodiment of the present invention, the sample box 83 includes a box body 831. A drainage groove 833 is provided at one end of the bottom of the box body 831. Guide strips 835 are fixedly connected to both sides of the box body 831. Both guide strips 835 are slidably engaged with the detection seat 82. A mating groove 821 is provided on the inner side of the detection seat 82, which is slidably engaged with the guide strips 835. A plurality of through drainage holes 822 are provided on the bottom wall of the detection seat 82. A stop block 836 that abuts against the locking component 85 is fixedly connected to the outer side of the box body 831. A mesh cover plate 832 is snapped onto the top of the box body 831. A clamping member 837 for fixing the mesh cover plate 832 is provided at one end of the top of the box body 831.

[0047] In this embodiment, the housing 831 slides into the docking groove 821 of the detection seat 82 via the guide strip 835, facilitating installation and disassembly. The drainage groove 833 and drainage hole 822 allow hot water to flow in and out, ensuring uniform heating of the original membrane. The stop block 836 is used to fix the position in conjunction with the locking component 85. The clamping component 837 fixes the mesh cover plate 832 to prevent the original membrane from shifting. The sample box 83 is reasonably designed, and the guide strip 835 and docking groove 821 ensure accurate positioning. The drainage structure avoids water accumulation and ensures uniform heating. The clamping component 837 improves sealing and reduces errors.

[0048] In a further preferred embodiment of the present invention, the clamping member 837 includes a pressure plate 8371 rotatably connected to the top of the box body 831, a rotating cap 8372 coaxially fixedly connected to the pressure plate 8371, and a first torsion spring 8373 sleeved on the rotating shaft of the pressure plate 8371. The two ends of the first torsion spring 8373 are respectively welded to the pressure plate 8371 and the top wall of the box body 831.

[0049] In this embodiment, the clamping component 837 includes a pressure plate 8371, a rotating cap 8372, and a first torsion spring 8373. The pressure plate 8371 is rotatably connected to the top of the housing 831. By manually rotating the rotating cap 8372, the first torsion spring 8373 provides a restoring force, causing the pressure plate 8371 to press the mesh cover plate 832. When the original film needs to be replaced, rotating the pressure plate 8371 can easily open it. The clamping component 837 has a simple structure and is easy to operate. The first torsion spring 8373 ensures stable clamping force, prevents the mesh cover plate 832 from loosening, and improves the reliability of detection.

[0050] In a further preferred embodiment of the present invention, the locking component 85 includes a turntable 851 fixedly connected to the bottom end of the sleeve 84. The outer edge of the turntable 851 is hinged with a plurality of connecting rods 852 corresponding one-to-one with the box body 831. The ends of the plurality of connecting rods 852 away from the turntable 851 are all hinged with abutment blocks 853. The top of the detection seat 82 is provided with a sliding groove 854 that is slidably connected to the abutment blocks 853. The top of the detection seat 82 is provided with a plurality of limiting members 855 corresponding one-to-one with the abutment blocks 853.

[0051] In this embodiment, the turntable 851 is fixedly connected to the bottom end of the sleeve 84. When the drive member 87 drives the sleeve 84 to rotate, the turntable 851 rotates, pushing the abutment block 853 to slide in the slide groove 854 through the connecting rod 852. The abutment block 853 abuts against the stop block 836 of the sample box 83 to achieve fixation. The limiting member 855 ensures that the position of the abutment block 853 is accurate. The locking component 85 enables quick locking and unlocking of the sample box 83. The lever effect of the connecting rod 852 and the turntable 851 increases the locking force and improves stability. The limiting member 855 prevents over-positioning and ensures safety.

[0052] In a further preferred embodiment of the present invention, the limiting member 855 includes a pin 8551 rotatably connected to the top of the detection seat 82, a limiting plate 8552 fixedly connected to the top of the pin 8551, one end of the limiting plate 8552 abutting against the stop block 836, and the other end of the limiting plate 8552 abutting against the abutting block 853. A second torsion spring 8553 is sleeved on the pin 8551, and the two ends of the second torsion spring 8553 are respectively welded to the limiting plate 8552 and the detection seat 82.

[0053] In this embodiment, the second torsion spring 8553 provides torque to keep the limiting plate 8552 under pressure, ensuring that the sample box 83 is fixed and does not shift. The limiting component 855 plays a double safety role. The elasticity of the second torsion spring 8553 ensures that the limiting plate 8552 is always in contact, preventing the sample box 83 from shaking during heating and improving detection accuracy.

[0054] In a further preferred embodiment of the present invention, the sealing component 86 includes a plurality of branch pipes 861 fixedly connected to the bottom end of the oil injection pipe 81 and communicating with the oil injection pipe 81.

A first sliding rod 862 penetrating the inner wall of the branch pipe 861 is fixedly connected to one end of each of the plurality of first sliding rods 863. The plurality of first sliding rods 862 are slidably connected to the corresponding branch pipes 861. A sealing plate 864 is fixedly connected to one end of each of the plurality of first sliding rods 862 away from the first piston 863. A slot 834 is provided on one side of the box body 831 to slide with the sealing plate 864. The bottom of the sealing plate 864 abuts against the bottom end of the drainage groove 833.

[0055] In this embodiment, the branch pipe 861 is connected to the oil injection pipe 81. When the oil supply component 88 injects oil into the oil injection pipe 81, the oil pressure pushes the first piston 863, and the first slide rod 862 drives the sealing plate 864 to insert into the slot 834 of the box body 831, sealing the bottom of the drain groove 833 to achieve a seal. When the oil pressure is released, the sealing plate 864 resets. The sealing component 86 is driven by oil pressure, ensuring a reliable seal and preventing hot water leakage. The sealing plate 864 fits tightly with the slot 834, ensuring that the bottom of the sample box 83 is completely sealed and reducing detection interference.

A cam 887 is also fixedly connected to the output shaft of the first motor 873. The outer edge of the cam 887 is rotatably connected to the rotating plate 888.

[0059] In this embodiment, the first motor 873 drives the cam 887 to rotate, and the cam 887 pushes the rotating plate 888. The rotating plate 888 hinges to the slider 881, allowing the slider 881 to slide within the guide groove 882. The second slide rod 884 connects to the second piston 885.
