Abstract
Description
Technical Field
[0001] This utility model relates to the field of foam manufacturing technology, specifically to a quality testing device for foam products. Background Technology
[0002] Foam products are lightweight, expandable products manufactured through chemical reactions or physical methods. Their main characteristics are large volume, light weight, high flexibility, and certain elasticity and thermal insulation properties. Foam products are typically made from man-made materials such as polyurethane, polystyrene, and polypropylene. These materials have good plasticity and stability, making them easy to process and produce. Rigid foams are mainly used in the manufacture of insulation materials, fillers, and decorative panels.
[0003] Currently, there is a lack of equipment for testing the quality of foam products. Most of the judgment is made based on the practical experience of workers or by improving based on customer feedback after the products are sold. This can lead to cost losses and reduced sales, making it impossible to guarantee quality and affecting the overall manufacturing efficiency of foam products. Existing impact testing equipment or compression testing equipment cannot be adjusted to adapt to multiple different test objects. Foam products are inherently fragile, so the testing equipment needs to have adjustable functions to test the impact and pressure resistance data that meet the requirements.
[0004] Therefore, it is necessary to design a quality testing device for foam products that is practical and can automatically detect defects. Utility Model Content
[0005] The purpose of this invention is to provide a quality testing device for foam products to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a quality testing device for foam products, comprising a base and a support frame, a turntable connected to the upper bearing of the support frame, a sliding cylinder disposed above the support frame, a rotating wheel disposed on the outer side of the rotating shaft of the turntable, a first connecting rod connected to the outer bearing of the rotating wheel, a second connecting rod connected to the front bearing of the first connecting rod, the second connecting rod being slidably connected to the support frame, a detection plate disposed at the outer end of the second connecting rod, and a detector disposed above the support frame.
[0007] According to the above technical solution, a piston cylinder is fixedly installed on the rear side of the detection plate, an impact plate is provided at the piston end of the piston cylinder, a spring is wrapped around the outside of the piston end of the piston cylinder, and a fixing frame is provided above the base.
[0008] According to the above technical solution, a slide rail is fixedly installed above the base, and a control base is slidably connected above the slide rail. A slide rod is provided inside the control base, and a slider is slidably connected to the outside of the slide rod. A threaded rod is engaged with the inside of the slider, and the threaded rod is mutually bearing-connected to the control base. A motor is provided on the outside of the control base, and the output shaft of the motor is mutually connected to the threaded rod. The slider and the support frame are fixedly connected to each other.
[0009] According to the above technical solution, a first helical gear is connected to the outer bearing of the other end of the control base. The first helical gear is connected to a threaded rod. A first support rod is fixedly installed on the top of the base. A second support rod is fixedly installed on the top of the base. A transmission rod is connected to the bearing at the left end of the first support rod. The transmission rod is meshed with the first helical gear. A second helical gear is connected to the bearing at the left end of the second support rod. The transmission rod is meshed with the second helical gear. A rotating shaft is provided on the rear side of the second helical gear. A sliding sleeve is provided on the right side of the rotating shaft of the turntable. The sliding sleeve is slidably connected to the rotating shaft.
[0010] Compared with the prior art, the beneficial effects achieved by this utility model are:
[0011] (1) By setting a transmission rod, when the motor drives the threaded rod to rotate to achieve the left and right displacement of the support frame, the threaded rod will drive the first helical gear to rotate, and drive the second helical gear to rotate through the transmission rod, thereby rotating through the retractable sliding sleeve and the rotating shaft, and finally driving the turntable to rotate, so as to achieve the displacement while performing impact test and extrusion test, and reduce costs through linkage effect;
[0012] (2) By setting up a piston cylinder, different thicknesses of foam products require different test distances. In order to prevent the test plate from extending too far at the beginning and directly damaging the foam products, or the distance from extending too far and being unable to be tested, the test will not yield accurate results and will also increase costs, the front and rear positions of the support frame are adjusted before the test. The test plate is adjusted to the maximum extension distance, and the piston cylinder retracts, causing the impact plate to move backward. At this time, the impact plate is in contact with the test plate. Then the turntable is rotated to restore it to its initial state, and the position of the support frame is finely adjusted forward. At this time, the distance is just enough to have impact force when impacting, and the foam products are tested for whether they are damaged. When the extrusion test is performed, the piston cylinder releases the internal piston rod, the spring rebounds and causes the impact plate to extend forward and be in contact with the foam products. At this time, the turntable is rotated slowly. The spring will provide additional thrust at the previous distance, and the extrusion resistance of the foam products is tested by whether they are damaged.
[0013] (3) When testing the quality of foam products by setting up a detection plate, expansion test and compression test will be performed. At this time, after the worker fixes the foam product, the device will start. The turntable will rotate, driving the rotating wheel to rotate. Through the cooperation of the first link and the second link, the second link can move back and forth inside the slide cylinder. At this time, the detection plate will repeatedly impact the fixed foam product to achieve the impact test. By adjusting the position of the support frame and slowly rotating the turntable at a certain angle, the detection plate will compress the foam product to achieve the compression test. Before the detection plate extends to the top, the extension speed will slow down due to the impact and compression, resulting in a short period of slow rotation of the turntable. Conversely, when the reciprocating motion of the detection plate has no slow interval, it means that there is no resistance in front of the detection plate, which means that the foam product is broken. The detector needs to detect the rotation speed of the turntable. When the rotation speed no longer has a slow interval, it means that the foam product has cracks or damage, thus ending the test.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figure 1-3This utility model provides a technical solution: a quality testing device for foam products, including a base 1, a support frame 8, a turntable 9 connected to the upper bearing of the support frame 8, a slide cylinder 14 disposed above the support frame 8, a rotating wheel 11 disposed on the outer side of the rotating shaft of the turntable 9, a first connecting rod 12 connected to the outer bearing of the rotating wheel 11, a second connecting rod 13 connected to the front bearing of the first connecting rod 12, the second connecting rod 13 being slidably connected to the support frame 8, a detection plate 26 disposed at the outer end of the second connecting rod 13, and a detector 10 disposed above the support frame 8. When the quality of the foam product needs to be tested, an expansion test and a compression test will be performed. After the worker fixes the foam product, the device is started, the turntable 9 will rotate, driving the rotating wheel 11 to rotate, and the first connecting rod 12 and the second connecting rod 13 will rotate. The cooperation of the three links allows the second link 13 to move back and forth inside the slide cylinder 14. At this time, the detection plate 26 will repeatedly impact the fixed foam product to achieve the impact test. By adjusting the position of the support frame 8 and slowly rotating the turntable 9 at a certain angle, the detection plate 26 will squeeze the foam product to achieve the compression test. Before the detection plate 26 extends to the top, the extension speed will slow down due to the impact and compression, resulting in a short period of slow rotation of the turntable 9. Conversely, when the reciprocating motion of the detection plate 26 has no slow interval, it means that there is no resistance in front of the detection plate 26, which means that the foam product is broken. The detector 10 needs to detect the rotation speed of the turntable 9. When the rotation speed no longer has a slow interval, it means that the foam product has cracks or damage, thus ending the test.
[0020] A piston cylinder 15 is fixedly mounted on the rear side of the detection plate 26. An impact plate 17 is provided at the piston end of the piston cylinder 15, and a spring 16 is wrapped around the outside of the piston end of the piston cylinder 15. A fixing frame 18 is provided above the base 1. When performing impact and compression tests, foam products of different thicknesses require different test distances. In order to prevent the detection plate 26 from extending too far initially, which would directly damage the foam products, or from extending too far, which would prevent the test from being conducted and would not yield accurate results and would also increase costs, the detection plate 26 is adjusted to its maximum extension distance by adjusting the front and rear positions of the support frame 8 before the test. After the impact, the piston cylinder 15 retracts, causing the impact plate 17 to move backward. At this time, the impact plate 17 is in contact with the detection plate 26. Then the turntable 9 is rotated to return it to its initial state, and the position of the support frame 8 is finely adjusted forward. At this time, the distance is just enough to have an impact force when impacting, to test whether the foam product is damaged. When the compression test is performed, the piston cylinder 15 releases the internal piston rod, and the spring 16 rebounds, causing the impact plate 17 to extend forward and be in contact with the foam product. At this time, the turntable 9 is slowly rotated. At the previous distance, the spring 16 will provide additional thrust to test the compression resistance of the foam product by whether it is damaged.
[0021] A slide rail 2 is fixedly installed on the top of the base 1. A control base 3 is slidably connected to the top of the slide rail 2. A slide rod 5 is set inside the control base 3. A slider 7 is slidably connected to the outside of the slide rod 5. A threaded rod 6 is engaged with the inside of the slider 7. The threaded rod 6 is connected to the control base 3 by bearings. A motor 4 is set on the outside of the control base 3. The output shaft of the motor 4 is connected to the threaded rod 6. The slider 7 is fixedly connected to the support frame 8. When the motor 4 of the control base 3 is started, it drives the threaded rod 6 to rotate, causing the slider 7 on the slide rod 5 to slide left and right, realizing the left and right displacement of the upper support frame 8. Thus, the impact test can be performed on other positions in addition to the center position of the foam product. The distance of the front and back displacement can be adjusted by the bottom slide rail 2.
[0022] The outer bearing of the other end of the control base 3 is connected to a first helical gear 19, which is connected to the threaded rod 6. A first support rod 20 is fixedly installed on the top of the base 1, and a second support rod 21 is fixedly installed on the top of the base 1. A transmission rod 22 is connected to the left end bearing of the first support rod 20, and the transmission rod 22 is meshed with the first helical gear 19. A second helical gear 23 is connected to the left end bearing of the second support rod 21, and the transmission rod 22 is meshed with the second helical gear 23. A rotating shaft 24 is provided on the rear side of the second helical gear 23. A sliding sleeve 25 is provided on the right side of the rotating shaft of the turntable 9, and the sliding sleeve 25 is slidably connected to the rotating shaft 24. When the motor 4 drives the threaded rod 6 to rotate and realize the left and right displacement of the support frame 8, the threaded rod 6 will drive the first helical gear 19 to rotate, which will drive the second helical gear 23 to rotate through the transmission rod 22. This will then drive the turntable 9 to rotate through the retractable sliding sleeve 25 and the rotating shaft 24, thus realizing the displacement while performing impact and compression tests. The linkage effect reduces costs.
