Description

Technical Field

[0001] This utility model relates to the technical field of memory pillow manufacturing equipment, specifically to a memory pillow softness testing device. Background Technology

[0002] Memory foam pillows are pillows made primarily of memory foam, a slow-rebound material, often polyurethane. The manufacturing process requires a testing device that allows operators to more intuitively and accurately assess the pillow's firmness.

[0003] Existing memory foam pillows lack a more intuitive way to test their firmness during use. Current pillow softness tests are highly subjective and lack objective standards. They mainly rely on manual pressing or simple pressure tests, which can lead to deviations in results due to different personnel or testing environments. Furthermore, they cannot be used to test softness based on human head shape.

[0004] Therefore, it is necessary to invent a memory pillow softness testing device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a memory pillow softness testing device to solve the problem that the softness and hardness of the pillow cannot be tested more intuitively during use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a memory pillow softness testing device, comprising a testing frame, a testing table, a pillow body, a pressure plate, a push rod, a motor, a controller, and a shaped component. The testing table is located on the lower inner side of the testing frame, and the pillow body is placed on the inner side of the testing table. A pressure plate is located directly above the pillow body, positioned above the inner side of the testing frame. A push rod is installed above the center of the surface of the pressure plate, and a motor is connected above the push rod. A controller is located above the front side wall of the testing frame, and a shaped component is located at the bottom of the pressure plate.

[0007] Preferably, the outer walls of the test platform are open on both sides, and the front and rear walls of the test platform are provided with several notches on both sides and in the middle.

[0008] Preferably, the inner cavity shape of the test platform matches the shape of the pressure plate, and a scale is installed in the middle of each notch.

[0009] Preferably, the bottom end of the push rod is provided with a detachable part, a detachable column is installed below the detachable part, and an installation sleeve is provided directly below the detachable column.

[0010] Preferably, the outer wall of the detachable column is provided with threads, and the middle part of the mounting sleeve is provided with a threaded groove that matches the threads of the detachable column, and a pressure sensor is installed in the middle of the inner bottom surface of the threaded groove.

[0011] Preferably, the bottom irregular part of the pressure plate consists of multiple arc-shaped plates fixedly assembled together, and the two side walls of the irregular part are attached to the lower sides of the outer wall of the pressure plate.

[0012] Preferably, positioning holes are provided on both sides of the irregular part, and a pin is installed through the middle of the positioning hole. The pin passes through the middle of the pressure plate from the positioning hole at one end of the irregular part and continues to the positioning hole at the other end of the irregular part.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] This memory foam pillow softness testing device uses irregularly shaped components made of multiple curved plates fixed together to form a curved surface structure similar to the contour of the human head. In actual use, the head does not make flat contact with the pillow, but rather the head conforms to the pillow surface in a curved manner. This design can more realistically simulate the contact state between the head and the pillow, test the rebound characteristics of the memory foam pillow under curved contact, adapt to irregularly shaped pillows, expand the testing range, broaden the testing range of different types of pillows, meet the needs of comprehensive testing of diverse pillow products, and improve the versatility and applicability of the equipment.

[0015] It supports quick replacement of pressure heads of different specifications to meet the testing needs of different types of memory foam pillows, such as testing the softness of memory foam pillows of different materials and structures, improving the versatility and flexibility of the equipment. The detachable design facilitates the cleaning, repair or replacement of irregular parts. When irregular parts are worn or deformed due to long-term use, new irregular parts can be replaced in time to extend the overall service life of the equipment and reduce usage costs.

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] This utility model provides, for example Figure 1-5 The device shown is a memory foam pillow softness testing device, including a testing frame 1, a testing table 2, a pillow body 3, a pressure plate 4, and a push rod 5. The testing table 2 is arranged on the lower inner side of the testing frame 1. The outer walls of the testing table 2 are open on both sides. Several notches 201 are opened on both sides and the middle of the front and rear walls of the testing table 2. The inner cavity shape of the testing table 2 matches the shape of the pressure plate 4. A scale 202 is installed in the middle of each notch 201. The pillow body 3 is placed inside the testing table 2. The pressure plate 4 is arranged on the top of the pillow body 3. Pressure plate 4 is located on the inner side of the detection frame 1. A push rod 5 is installed on the upper part of the middle of the surface of the pressure plate 4. A detachable part 501 is provided at the bottom end of the push rod 5. A detachable column 502 is installed below the detachable part 501. An installation sleeve 503 is provided directly below the detachable column 502. The outer wall of the detachable column 502 is provided with threads. A threaded groove 504 matching the thread of the detachable column 502 is opened in the middle of the installation sleeve 503. A pressure sensor 505 is installed in the middle of the inner bottom surface of the threaded groove 504.

[0025] A motor 6 is connected above the push rod 5. A controller 7 is installed above the front side wall of the detection frame 1. A special-shaped part 8 is installed at the bottom of the pressure plate 4. The special-shaped part 8 at the bottom of the pressure plate 4 consists of multiple arc-shaped plates fixed together. Both sides of the special-shaped part 8 are attached to the lower sides of the outer wall of the pressure plate 4. Both sides of the special-shaped part 8 are provided with positioning holes 801. A pin 802 is installed through the middle of the positioning hole 801. The pin 802 passes through the positioning hole 801 at one end of the special-shaped part 8 and through the middle of the pressure plate 4 until it exits from the positioning hole 801 at the other end of the special-shaped part 8.

[0026] The pressure application time and force of the device are controlled by the controller 7. The user records the pressure and pressure application time displayed, observes the position of the pillow body 3 on the scale 202 after the pressure plate 4 is lifted, and records the data. The pillow position is adjusted by the scale notches 201 on both sides of the test platform 2 to ensure that the test area is consistent. The pressure, pressure holding time and number of tests are set by the controller 7. The device is started to conduct the test. After the pressure is applied, the deformation of the pillow is observed, the maximum sinking depth is recorded by reading the scale.

[0027] The pressure sensor 505, motor 6 and controller 7 mentioned above are all existing technology products, and their specific structures and functions will not be described in detail here.

[0028] The working principle of this practical application is as follows:

[0029] Refer to the instruction manual appendix Figure 1-5 The device uses a motor 6 to drive a push rod 5 to apply vertical pressure to a pressure plate 4, simulating the pressure of a human head on a memory foam pillow. A pressure sensor 505 detects the pillow's rebound force and deformation degree to assess its softness. The motor 6 drives the push rod 5 downward, causing the pressure plate 4 and the irregular part 8 to press against the pillow body 3. The pressure sensor 505 monitors the applied pressure value in real time. The pressure plate 4 is held for a certain period of time to allow the pillow to deform fully. The depth of the pillow sinking is observed at the scale 201. The motor 6 drives the push rod 5 upward, and the pressure plate 4 leaves the pillow surface. The pressure sensor 505 records the rebound force curve and calculates parameters such as rebound time and residual deformation rate. The pressure time and force of the device are controlled by a controller 7. The user records the pressure and pressure time displayed and observes the position of the pillow body 3 at the scale 202 after the pressure plate 4 is lifted, and records the data.

[0030] When using the device, place it on a stable platform, connect the power supply, and check whether the pressure plate 4 and the irregular part 8 are firmly installed. Ensure that the pin 802 is fixed in place. Select the appropriate detachable column 502 according to the test requirements. Different pressure heads can be replaced for different hardness tests. Place the pillow 3 to be tested flat on the test platform 2, ensuring that its center is aligned with the pressure plate 4. Adjust the position of the pillow through the notch 201 on both sides of the scale on the test platform 2 to ensure that the test area is consistent. Set the pressure intensity, pressure holding time and number of tests through the controller 7, start the device to perform the test, and observe the deformation of the pillow after the pressure is applied. Record the maximum sinking depth and read the scale.
