Abstract
Description
Technical Field
[0001] This utility model relates to the field of sponge testing technology, specifically a sponge resilience performance testing device. Background Technology
[0002] Sponges are made of wood cellulose fibers or foamed plastic polymers and are one of the main components of sofas. Sofa sponges need to have a certain degree of resilience. When a person sits on the sofa, the sponge will be compressed under pressure. After the person leaves the sofa, the sponge should be able to quickly rebound so that the sofa returns to its original shape. If the sofa sponge has poor resilience, it will be too soft, resulting in a slow rebound after the person leaves the sofa. The sofa will not be able to quickly return to its original shape, which will affect its use.
[0003] Existing resilience testing devices involve placing a sponge inside the equipment, pressurizing it with hydraulic pressure, and then removing the hydraulic pressure device to test the sponge's resilience. This method requires removing the sponge after testing and placing a new sponge inside the equipment for testing, resulting in low testing efficiency. Therefore, a new sponge resilience performance testing device has been proposed. Utility Model Content
[0004] In view of the shortcomings of the prior art, this utility model provides a sponge resilience performance testing device to solve the problems mentioned in the background art.

[0006] Furthermore, side plates are fixedly connected to the outer surfaces of both the front and rear sides of the threaded block, and a second electric push rod is fixedly installed on the bottom outer surface of each side plate. A connecting plate is fixedly connected to the output end of the second electric push rod, and an infrared transmitter and an infrared receiver are respectively installed between the opposite outer surfaces of the two connecting plates.

[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. This sponge resilience testing device uses a motor to drive a lead screw to rotate, which in turn moves a threaded block to adjust the position of the pressure plate. A first electric push rod drives the pressure plate to press the sponge, and a second electric push rod, in conjunction with an infrared transmitter and receiver, performs resilience testing on the sponge. After testing, the sponge is transported by a conveyor belt for continuous testing, thus improving the efficiency of sponge testing.

[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] Example 1:
[0020] Please refer to the following: Figures 1-3 This utility model provides a technical solution: a sponge resilience performance testing device, including a conveyor belt 1, a gantry frame 2 fixedly connected to the top outer surface of the frame of the conveyor belt 1, a lead screw 3 rotatably connected between the left and right outer surfaces of the gantry frame 2, a motor 4 fixedly installed on the outer surface of the gantry frame 2, the output end of the motor 4 fixedly connected to the lead screw 3, a threaded block 5 threadedly connected to the outer surface of the lead screw 3, a first electric push rod 6 fixedly installed on the bottom outer surface of the threaded block 5, and a pressure plate 7 fixedly connected to the output end of the first electric push rod 6. Specifically, the sponge to be tested is conveyed onto the conveyor belt 1, the lead screw 3 is driven to rotate by the motor 4, the threaded block 5 is adjusted to move, the threaded block 5 drives the pressure plate 7 to move, the position of the pressure plate 7 is adjusted so that the pressure plate 7 is precisely aligned with the sponge, the pressure plate 7 is driven to move downward by the first electric push rod 6, the pressure plate 7 presses the sponge, and the first electric push rod 6 is retracted to test the sponge's resilience performance. After the test is completed, the sponge is conveyed by the conveyor belt 1 for continuous testing, which improves the testing efficiency of the sponge.
[0021] In this embodiment, side plates are fixedly connected to the outer surfaces of both the front and rear sides of the threaded block 5. A second electric push rod 8 is fixedly installed on the bottom outer surface of each side plate. A connecting plate 9 is fixedly connected to the output end of the second electric push rod 8. An infrared emitting end 10 and an infrared receiving end 11 are respectively installed between the opposite outer surfaces of the two connecting plates 9. Specifically, the connecting plate 9 is moved by the second electric push rod 8 so that the infrared light is located at a suitable position where it can be blocked by the sponge. When the sponge's resilience is tested, if the sponge rebounds to a position where it can block the infrared light, it indicates that the resilience is good. If it cannot rebound to a position where the infrared light is blocked, it indicates that the resilience is poor.
[0022] In this embodiment, the top outer surface of the frame of the conveyor belt 1 is fixedly connected to the outer surfaces of both front ends with fixed plates 12. The outer surface of the fixed plates 12 is threaded with adjusting screws 13. The other end of the adjusting screws 13 is rotatably connected to guide plates 14. Specifically, by rotating the adjusting screws 13, the adjusting screws 13 drive the guide plates 14 to move, so that the guide plates 14 move to a position corresponding to the size of the sponge. The guide plates 14 guide the sponge, so that the sponge is in a relatively central position and is transported stably.
[0023] In this embodiment, a slide rod 16 is fixedly connected between the outer surfaces of the left and right sides of the portal frame 2, and a threaded plate is movably sleeved on the outer surface of the slide rod 16. Specifically, when the lead screw 3 rotates, it drives the threaded block 5 to slide on the surface of the slide rod 16, so that the threaded block 5 moves stably.
[0024] In this embodiment, two limiting rods 15 are movably inserted into the outer surface of the fixing plate 12. The other end of the limiting rod 15 is fixedly connected to the guide plate 14. Specifically, when the adjusting screw 13 rotates and drives the guide plate 14 to move, the limiting rod 15 slides inside the fixing plate 12, preventing the guide plate 14 from rotating with the rotation of the adjusting screw 13.
[0025] In this embodiment, the front side of the guide plate 14 is inclined to both sides, and the outer surface of the guide plate 14 is a smooth outer surface. Specifically, the sponge is guided by the inclined end so that the sponge is located between the two guide plates 14.
[0026] Working Principle: In use, the sponge to be tested is conveyed onto conveyor belt 1. Motor 4 drives screw 3 to rotate, adjusting threaded block 5 to move. Threaded block 5 drives pressure plate 7 to move, adjusting the position of pressure plate 7 so that it precisely aligns with the sponge. First electric push rod 6 drives pressure plate 7 downward, pressing the sponge. First electric push rod 6 retracts, testing the sponge's rebound performance. Second electric push rod 8 drives connecting plate 9 to move, positioning the infrared light at a suitable position where it is blocked by the sponge. When testing the sponge's rebound performance, if the sponge rebounds to the point where it can block the infrared light, the rebound performance is good; if it cannot rebound to the point where the infrared light is blocked, the rebound performance is poor. After testing, the sponge is conveyed back onto conveyor belt 1 for continuous testing, improving the efficiency of sponge testing.
[0027] By rotating the adjusting screw 13, the adjusting screw 13 drives the guide plate 14 to move, so that the guide plate 14 moves to a position corresponding to the size of the sponge. The guide plate 14 guides the sponge, so that the sponge is in a relatively central position and is transported stably.
