Description

Technical Field

[0001] This utility model relates to the field of mattress testing technology, specifically a rolling test machine for mattress durability testing. Background Technology

[0002] A mattress is a mat placed on a bed for people to rest on. As people's living standards improve, their requirements for mattress comfort are also increasing. Therefore, before mass production, mattresses are tested for performance using testing machines. However, existing testing machines have certain shortcomings in use. They are inconvenient to operate, bulky, and inefficient. They cannot perform rolling pressure resistance tests or static load pressure resistance tests, and can only perform local testing. They cannot perform repeated testing for extended periods, thus failing to systematically determine the elasticity and pressure resistance of mattresses.

[0003] Patent announcement number CN202204658U discloses a mattress rolling durability testing machine. By placing the mattress to be tested on the machine frame and then turning the handwheel to move the roller towards the mattress, when the roller contacts the mattress and generates a certain pressure, the crank slider mechanism drives the moving platform to move back and forth. The roller installed on the moving platform rolls with the back and forth movement of the moving platform, applying pressure evenly to the mattress, and performing a pressure resistance test on the mattress. Multiple tests are conducted to detect the mattress's long-term pressure resistance, so as to produce a high-quality mattress.

[0004] In the aforementioned patent, the testing machine solves the problems mentioned above. However, the testing machine still has the following problems: during the use of the testing machine, the mattress to be tested needs to be placed manually on the top of the machine frame. Then, the mattress can be pressed and tested by rollers and loading pads. However, manual placement can easily cause the mattress to shift. Furthermore, the placement of the mattress is easily affected by external factors. The process of adjusting the position of the mattress is time-consuming, which can easily lead to low testing efficiency of the testing machine.

[0005] To address the aforementioned issues, there is an urgent need for innovative design based on the existing testing machine structure. Utility Model Content

[0006] The purpose of this utility model is to provide a rolling test machine for mattress durability testing, in order to solve the problem mentioned in the background art that the test machine requires manual placement of the mattress to be tested on the upper part of the machine frame, and then the mattress can be pressed by the roller and the loading pad. However, manual placement is prone to mattress displacement, and the placement of the mattress is easily affected by external factors. The time spent in adjusting the position of the mattress is wasted, which easily leads to low testing efficiency of the test machine.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a rolling test machine for mattress durability testing, comprising a base and a support frame fixedly installed on the upper end of the base;

[0008] A workbench is fixedly installed on the upper end of the base, and the workbench is located inside the support frame. A pusher is slidably installed on the upper end of the workbench, and a mattress to be tested is provided on the upper end of the pusher. A power mechanism is fixedly installed on the lower end of the base, and a control rod is fixedly installed on the output end of the power mechanism, and the control rod is connected to the lower end of the pusher.

[0009] The support frame is equipped with a rolling structure for testing the resilience of the mattress after rolling, and a point pressure structure for testing the resilience of the mattress after point pressure.

[0010] Preferably, the rolling structure includes an adjusting rod and a motor assembly, wherein the adjusting rod is slidably mounted on the upper end of the support frame, and the motor assembly is slidably mounted on the upper end of the adjusting rod.

[0011] Preferably, a support rod is fixedly installed at the output end of the motor assembly, and roller assemblies are fixedly installed at both ends of the support rod. A guide rod is fixedly installed inside the support frame, and the roller assembly is slidably installed on the outside of the guide rod.

[0012] Preferably, a lifting structure is fixedly installed on the outer side of the roller assembly, and a lifting plate is slidably installed on the outer side of the lifting structure. A rolling cylinder is rotatably installed on the outer side of the lifting plate, and a rolling block is fixedly installed on the outer side of the rolling cylinder.

[0013] Preferably, the point pressure structure includes a positioning rod, which is fixedly installed on the outside of the support frame, and two sets of electric push rods are slidably installed on the outside of the positioning rod.

[0014] Preferably, the output end of the electric push rod is fixedly equipped with a pressing component, and the pressing component is located at the lower end of the moving component, and the two sets of pressing components are of different sizes.

[0015] Preferably, both the pressing element and the rolling cylinder are located at the upper end of the mattress to be tested, and the pressing element is located on the outside of the support frame.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1.

[0018] 2. Through the movement of the rolling structure, the rolling cylinder and rolling block can be rolled over the mattress under test, and the position of the rolling cylinder and rolling block rolling over the mattress under test can be changed, thereby improving the comprehensiveness of the test machine.

[0019] 3. Furthermore, through the movement of the point-pressure structure, two sets of pressing parts of different shapes can be used to squeeze the mattress under test, thereby mimicking the effect of the user's head, feet and buttocks pressing on the mattress, improving the practicality of the testing machine.

[0020] 4. Furthermore, by moving the roller assembly outside the guide rod, the friction between the structures during the rolling process of the rolling cylinder can be reduced, ensuring the smooth movement of the rolling structure and reducing wear between the rolling structures.

[0021] 5. Furthermore, it achieves fully automated combined testing of mattress durability and firmness, and can test mattresses of various sizes, making it more practical and applicable. Attached Figure Description

[0029] 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.

[0030] In a specific embodiment, such as Figure 1-4 The basic working process of the testing machine is shown in the figure.

[0031] The base 1 and the support frame 2 fixedly installed on the upper end of the base 1; a workbench 3 is fixedly installed on the upper end of the base 1 and the workbench 3 is located inside the support frame 2. A pusher 4 is slidably installed on the upper end of the workbench 3 and a mattress to be tested 5 is set on the upper end of the pusher 4. A power mechanism 6 is fixedly installed on the lower end of the base 1 and a control rod 7 is fixedly installed on the output end of the power mechanism 6 and the control rod 7 is connected to the lower end of the pusher 4.

[0032] When using the rolling tester for mattress durability testing, the mattress to be tested 5 needs to be placed on the pusher 4 at the top of the worktable 3. Then, the power mechanism 6 can be activated and the pusher 4 can be moved by the control lever 7, so that the mattress to be tested 5 moves to the bottom of the support frame 2. At this time, the rolling structure 8 and the point pressure structure 18 can be activated to test the performance of the mattress to be tested 5.

[0033] During this process, the rolling cylinder 9 rolls on the top of the mattress and crushes it, while the pressing component 22 moves vertically downward and presses the mattress. Then, the pressing component 22 and the rolling cylinder 9 can be separated from the mattress 5 to be tested, and the degree of indentation recovery of the mattress 5 to be tested can be observed, thus completing the working process of the testing machine.

[0034] In one specific embodiment, such as Figures 1-4 The working process of the internal rolling structure 8 of the testing machine is shown in the figure.

[0035] The support frame 2 is equipped with a rolling structure 8 for testing the resilience of the mattress 5 after rolling. The rolling structure 8 includes an adjusting rod 10 and a motor assembly 11. The adjusting rod 10 is slidably installed on the upper end of the support frame 2, and the motor assembly 11 is slidably installed on the upper end of the adjusting rod 10.

[0036] A support rod 12 is fixedly installed at the output end of the motor assembly 11, and roller assemblies 13 are fixedly installed at both ends of the support rod 12. A guide rod 14 is fixedly installed inside the support frame 2, and the roller assembly 13 is slidably installed on the outside of the guide rod 14.

[0037] A lifting structure 15 is fixedly installed on the outer side of the roller assembly 13, and a lifting plate 16 is slidably installed on the outer side of the lifting structure 15. A rolling cylinder 9 is rotatably installed on the outer side of the lifting plate 16, and a rolling block 17 is fixedly installed on the outer side of the rolling cylinder 9.

[0038] When using the mattress durability testing rolling machine, after the mattress 5 to be tested is moved into the support frame 2, the rolling structure 8 can be activated. At this time, the motor assembly 11 will operate, causing the support rod 12 to move inside the support frame 2. During the movement of the support rod 12, it will move through the roller assembly 13 inside the support frame 2. The roller assembly 13 will simultaneously drive the lifting structure 15 to move horizontally. The horizontal movement of the lifting structure 15 will drive the lifting plate 16 and the rolling cylinder 9 to move, thereby changing the position of the rolling cylinder 9 at the upper end of the mattress 5 to be tested. Then, the lifting structure 15 can make the lifting plate 16 move downward and make the rolling cylinder 9 contact the mattress 5 to be tested. The motor assembly 11 continues to work and can drive the lifting structure 15 and the lifting plate 16 to continue to move horizontally. At this time, the rolling cylinder 9 will roll and drive the rolling block 17 to move, thereby crushing the upper end of the mattress 5 to be tested. After the crushing is completed, the rolling cylinder 9 moves upward and separates from the mattress 5 to be tested. At this time, the performance of the mattress 5 to be tested can be judged by the degree of indentation of the mattress 5 to be tested. Thus, the working process of the rolling structure 8 is completed, which effectively improves the practicality of the rolling structure 8.

[0039] Based on the above embodiments, such as Figures 1-2 and Figures 5-6 The working process of the point pressure structure 18 is disclosed as shown.

[0040] The support frame 2 is equipped with a point pressure structure 18 for testing the resilience of the mattress after 5 points of pressure.

[0041] The point pressure structure 18 includes a positioning rod 19, which is fixedly installed on the outside of the support frame 2, and two sets of electric push rods 21 are slidably installed on the outside of the positioning rod 19.

[0042] The output end of the electric push rod 21 is fixedly equipped with a pressing member 22, and the pressing member 22 is located at the lower end of the moving member 20, and the two sets of pressing members 22 are of different sizes;

[0043] Both the pressing element 22 and the rolling cylinder 9 are located at the upper end of the mattress 5 to be tested, and the pressing element 22 is located on the outside of the support frame 2.

[0044] When using the rolling tester for mattress durability testing, the pressure of the human head and buttocks on the mattress 5 under test can be measured by pressing the mattress with the pressing element 22.

[0045] During this process, the two sets of electric push rods 21 need to be pushed to the designated position by the moving part 20. During this process, the moving part 20 will slide on the outside of the positioning rod 19. After the moving part 20 moves to the designated position, the two sets of electric push rods 21 can be activated. The activation of the electric push rods 21 will push the two sets of pressing parts 22 downward. During the downward movement of the pressing parts 22, they will squeeze the mattress 5 under test and cause the mattress 5 under test to be indented. After that, the pressing parts 22 can be separated from the mattress 5 under test, and the reset effect of the indented position of the mattress 5 under test can be observed. At the same time, the positions of the pressing parts 22 and the rolling cylinder 9 can be changed to judge the durability effect of various positions of the mattress 5 under test. Furthermore, the testing machine can use rolling cylinders 9 and pressing parts 22 of different shapes to improve the ease of use of the testing machine and increase the overall practicality.

[0046] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0047] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
