Description

Technical Field

[0001] This utility model relates to the field of testing machines, specifically a sponge comprehensive durability testing machine. Background Technology

[0002] The comprehensive durability testing machine for sponges belongs to the field of testing machine technology and is mainly used to evaluate the durability performance of sponge products during actual use, such as the fatigue resistance of sponge fillings in sofas, mattresses, and car seats. Its core function is to conduct cyclic loading tests on sponges by simulating complex working conditions such as human sitting pressure and rolling, to detect their deformation recovery ability, hardness changes, and structural integrity after long-term use. Traditional sponge durability testing typically uses the vertical indentation test method, which applies a vertical force to the sponge through a fixed plate to simulate the static sitting pressure process of a human body and records the thickness loss or hardness change of the sponge after repeated compression.

[0003] However, existing sponge durability testing machines have the following drawbacks: conventional designs can only perform vertical indentation tests in a single direction, failing to simulate the complex stress states that sponges may encounter in actual use. Specifically, they use a servo-electric cylinder to drive a fixed plate for direct pressing tests. When a person moves left and right or turns over on a seat, the sponge experiences a combination of rolling friction and lateral forces; this dynamic condition differs significantly from simple vertical pressing. Traditional fixed plates, due to structural limitations, cannot achieve reciprocating rolling motion in the horizontal direction, resulting in test results that cannot fully reflect the sponge's durability performance in real-world usage scenarios. Furthermore, vertical indentation tests primarily focus on the vertical deformation of the sponge, neglecting the impact of horizontal stress distribution on the sponge's microstructure, potentially causing discrepancies between test data and actual user experience. Utility Model Content

[0004] In order to overcome the shortcomings of existing technical solutions, this utility model provides a sponge comprehensive durability testing machine, which can effectively solve the technical problem that the existing sponge comprehensive durability testing machine can only perform vertical indentation tests on the sponge using conventional fixed plates, and cannot repeatedly perform left and right rolling tests on the sponge.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a sponge comprehensive durability testing machine, including a control console and a frame. The frame is vertically arranged on the control console. The frame is internally provided with a vertical pressing component and a reciprocating drive component. The reciprocating drive component includes a slide rail fixedly arranged inside the frame, a slider arranged on the slide rail, and a rotary motor. The slider is slidably connected to the slide rail. One end of the slider is provided with a clamping plate. The frame is internally provided with a first fastening seat and a second fastening seat. One end of the rotary motor passes through the first fastening seat and is rotatably connected to the first fastening seat. A rotatable movable roller is provided on the side of the second fastening seat. A synchronous belt is provided between the rotary motor and the movable roller. The rotary motor and the movable roller form a transmission cooperation through the synchronous belt. The slider is fixed to the synchronous belt by the clamping plate. The vertical pressing component includes a servo electric cylinder fixedly arranged at one end of the slider and a push rod arranged on the servo electric cylinder. The end of the push rod is provided with a rollable roller.

[0006] Furthermore, the surface of the control console forms a rolling zone for placing the sponge, and a number of baffles are provided at one end of the control console near the rolling zone, with adjacent baffles arranged symmetrically.

[0007] Furthermore, a force sensor is provided at the end of the push rod near the roller.

[0008] Furthermore, the surface of the frame is provided with a number of heat dissipation holes, which are evenly distributed between adjacent heat dissipation holes.

[0009] Furthermore, the console is equipped with a cooling fan, an air inlet at one end and an air outlet at the other end, forming a ventilation duct inside the console. When the cooling fan is blowing air, external air is drawn through the fan, flows from the air inlet through the ventilation duct, and exits from the air outlet, thus achieving heat dissipation inside the console.

[0010] Furthermore, the bottom of the console is provided with several foot cups, all of which are on the same horizontal plane.

[0011] Furthermore, a power interface is provided at one end of the console near the air outlet, which is used to connect an external power source for power supply.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: The sponge comprehensive durability testing machine of this utility model uses a reciprocating drive component that cooperates with a slide rail, a slider and a rotating motor, and uses synchronous belt transmission to realize the reciprocating motion of the slider, which in turn drives the roller to repeatedly press the sponge left and right. By using a roller instead of a traditional fixed plate, the rolling indentation test of the sponge is realized, which improves the accuracy and precision of the test. Attached Figure Description

[0023] The following is a detailed description of the sponge comprehensive durability testing machine of this utility model:

[0024] Example 1: As Figures 1-5As shown, the sponge comprehensive durability testing machine includes a control console 1 and a frame 2. The frame 2 is vertically mounted on the control console 1. Inside the frame 2 are a vertical pressing assembly 4 and a reciprocating drive assembly 3. The reciprocating drive assembly 3 includes a slide rail 304 fixedly mounted inside the frame 2, a slider 305 mounted on the slide rail 304, and a rotary motor 301. The slider 305 is slidably connected to the slide rail 304. One end of the slider 305 is provided with a clamping plate 308. Inside the frame 2 are a first fastening seat 302 and a second fastening seat 306. One end of the rotary motor 301 passes through the first fastening seat 302. 2. It is rotatably connected to the first fastening seat 302. The side of the second fastening seat 306 is provided with a rotatable movable roller 307. A synchronous belt 303 is provided between the rotating motor 301 and the movable roller 307. The rotating motor 301 and the movable roller 307 form a transmission cooperation through the synchronous belt 303. The slider 305 fixes the synchronous belt 303 through the clamping plate 308. The vertical pressing assembly 4 includes a servo electric cylinder 401 fixedly disposed at one end of the slider 305 and a push rod 402 disposed at the servo electric cylinder 401. The end of the push rod 402 is provided with a rollable roller 404.

[0025] The surface of the control console 1 forms a roller pressing area 10 for placing sponges. Several baffles 11 are provided at one end of the control console 1 near the roller pressing area 10, with adjacent baffles 11 arranged symmetrically. A force sensor 403 is provided at one end of the push rod 402 near the roller 404. Several heat dissipation holes 5 are provided on the surface of the frame 2, with adjacent heat dissipation holes 5 arranged at equal intervals. A cooling fan 7 is provided inside the control console 1. An air inlet 8 is provided at one end of the control console 1, and an air outlet 6 is provided at the other end. A ventilation duct is formed inside the control console 1. When the cooling fan 7 draws air, external air is drawn through the cooling fan 7, flows from the air inlet 8 through the ventilation duct, and exits from the air outlet 6, thus achieving heat dissipation inside the control console 1. Several foot cups 12 are provided at the bottom of the control console 1, all of which are on the same horizontal plane. A power interface 9 is provided at one end of the control console 1 near the air outlet 6, for connecting to an external power source for power supply.

[0026] In this embodiment, a roller pressing area 10 for placing the sponge is formed on the surface of the control console 1, which facilitates the placement and fixation of the sponge. Several baffles 11 are provided at one end of the control console 1 near the roller pressing area 10, and adjacent baffles 11 are symmetrically arranged, which can effectively prevent the sponge from shifting or slipping during the test. A force sensor 403 is provided at one end of the push rod 402 near the roller 404, which can monitor and record the force value borne by the sponge during the pressing process in real time, providing important data support for evaluating the durability performance of the sponge. Several heat dissipation holes 5 are provided on the surface of the frame 2, and adjacent heat dissipation holes 5 are equidistantly distributed, which helps to dissipate heat inside the sponge comprehensive durability testing machine, prevents the sponge comprehensive durability testing machine from overheating due to long-term operation, and extends the service life of the testing machine. The cooling fan 7 and ventilation ducts provided inside the control console 1 form air circulation through the air inlet 8 and the air outlet 6, realizing heat dissipation inside the control console 1, effectively reducing the internal temperature of the control console 1, and ensuring the stable operation of the testing machine. The power interface 9 is provided at one end of the control console 1 near the air outlet 6, which facilitates the connection to an external power source for power supply, providing stable power support for the testing machine.

[0027] In this embodiment, the automated cyclic testing of the sponge sample is achieved through the synergistic effect of the vertical pressing component 4 and the reciprocating drive component 3. The servo electric cylinder 401 drives the roller 404 to simulate actual working conditions such as human body sitting pressure and rolling. With the force sensor 403 monitoring the pressure data in real time, it can accurately control the loading force and automatically record the test curve, significantly improving the testing efficiency and data reliability.

[0028] In this embodiment, the control console 1 is also equipped with control buttons and a power switch. The main control circuit board is also installed inside the control console 1. The cooling fan 7, the rotating motor 301, the servo electric cylinder 401, and the force sensor 403 are all electrically connected to the control console 1 through wires. The control console 1 can control the opening and closing of the testing machine. The control console 1 and the main control circuit board inside, as well as the cooling fan 7, the rotating motor 301, the servo electric cylinder 401, and the force sensor 403, all adopt conventional existing technologies. The circuit diagrams and circuit principles of the various electronic components inside the sponge comprehensive durability testing machine, as well as the cooling fan 7, the rotating motor 301, the servo electric cylinder 401, and the force sensor 403, are all conventional existing technologies and will not be described in detail here.

[0029] In this embodiment of the sponge comprehensive durability testing machine, the reciprocating drive component 3 works in conjunction with the slide rail 304, the slider 305 and the rotating motor 301, and is driven by the synchronous belt 303 to realize the reciprocating motion of the slider 305, which in turn drives the roller 404 to repeatedly press the sponge left and right. By using the roller 404 instead of the traditional fixed plate, the rollable indentation test of the sponge is realized, which improves the accuracy and precision of the test.

[0030] In use, the sponge to be tested is placed in the roller pressing area 10 of the control console 1. The testing machine is turned on through the control console 1. The servo electric cylinder 401 drives the push rod 402 and the roller 404 to move towards the roller pressing area 10, so that the surface of the roller 404 contacts and presses the sponge. At this time, the rotating motor 301 drives the synchronous belt 303 to rotate, so that the synchronous belt 303 drives the slider 305 to move along the slide rail 304, so that the roller 404 rolls the sponge back and forth. The back and forth motion of the roller 404 simulates the actual working conditions such as human body sitting pressure and rolling. With the help of the force sensor 403 to monitor the pressure data in real time, the rolling indentation test of the sponge is realized.

[0031] Example 2: Figure 6 and Figure 7 As shown, the difference between Embodiment 2 and Embodiment 1 is that the end of the push rod 402 is provided with a pressing plate 405, and the end of the push rod 402 replaces the roller 404 with the pressing plate 405.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
