Description

Technical Field

[0001] The invention relates to the field of latex product manufacturing, in particular to a latex pillow compression deformation and rebound performance testing device. Background Art

[0002] Latex, as a soft foam polymer material, is a polymer material with an elastic and porous structure. It is widely used in home furnishing, packaging, medical and other fields. Latex pillows have excellent antibacterial effects and good elasticity. They can effectively buffer the pressure of the human body and have strong affinity. They can effectively improve the cervical and lumbar vertebrae and lower blood pressure. Latex pillows can effectively reduce the static electricity generated between the human body and the fibers, and the honeycomb structure can effectively and quickly dissipate the heat generated by the human body.

[0003] During the production of latex pillows, different performance latex pillows have different natural latex content, and their compressibility and elasticity will also vary according to market demand. Therefore, it is necessary to test the compressibility and resilience of latex pillows during the production process. In the patent with patent number: CN2021231409068, patent name: A device suitable for testing the elasticity of latex pillows, a device suitable for testing the elasticity of latex pillows is disclosed, including a base, a display screen is provided on the front of the base, a switch is fixedly installed on the front of the base and away from the display screen, and a support column is fixedly installed on the top of the base. The device suitable for testing the elasticity of latex pillows, through the setting of the force detector and the pressure applying instrument, makes the test body above the conveying plate completely under the pressure applying instrument. When the press starts and drives the piston rod to press the connecting platform downward, the pressure of the pressure applying instrument on the test body completely acts on the test body, and the test body will act downward on the force detector due to the downward pressure. The force detector can complete the test of the elasticity of the latex pillow by calculating the pressure received and the pressure applied by the pressure applying instrument, thereby obtaining the test result.

[0004] The prior art only utilizes a press to squeeze the latex pillow, which can only test the compressibility of the latex pillow, and this test cannot effectively test its resilience. The existing technology generally uses a falling ball rebound test device to test the rebound performance. This test device uses a free-fall impact of a steel ball to test the sample, and requires testers to take and place the steel ball and the sample. Since the mass of the steel ball is large, it is inconvenient for people to grab and it is easy to drop. In addition, during the test process, the resilience of the latex pillow under different compression conditions cannot be tested. The recovery conditions of the latex pillow are different in different compression states, and the resilience under different recovery conditions will also be different.

[0005] Therefore, there is an urgent need for a latex pillow compression deformation and rebound performance testing device to realize the compression deformation test of latex pillows and automatic rebound performance test, without the need for testers to repeatedly operate the instrument and keep a close eye on the equipment, thereby improving test efficiency.

DETAILED DESCRIPTION

[0018] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0019] like Figures 1 to 4 As shown, the following preferred technical solutions are provided: A latex pillow compression deformation and rebound performance testing device includes: a compression deformation test component 1 for testing the compression of a latex pillow and a rebound test component 2 for testing the rebound of a latex pillow. The compression deformation test component 1 and the rebound test component 2 are both installed on a workbench 3. The compression deformation test component 1 and the rebound test component 2 are both controlled by a display control device for controlling the operation of each component and displaying the test results. The compression deformation test component 1 is arranged opposite the rebound test component 2. The rebound test component 2 includes a falling ball rebound detection module 21 and a mobile positioning mechanism 22 for moving the latex pillow and the falling ball rebound detection module 21 and aligning and positioning the rebound position. The mobile positioning mechanism 22 is fixedly installed on the workbench 3. The falling ball rebound detection module 21 is installed on the mobile positioning mechanism 22. A steel ball suction mechanism 4 for sucking and resetting a steel ball is provided on one side of the mobile positioning mechanism 22 and the falling ball rebound detection module 21.

[0020] Specifically, in order to solve the technical problems of testing the compression deformation of latex pillows and testing the resilience of latex pillows under different compression conditions, the present invention uses a compression deformation test component 1 to test the compression deformation of latex pillows under different pressures, and uses a rebound test component 2 to test the resilience of latex pillows under different deformation conditions. The mobile positioning mechanism 22 controls the movement of the latex pillow between the compression deformation test component 1 and the falling ball rebound detection module 21, and simultaneously locates the rebound position during the falling ball rebound test. The steel ball suction mechanism 4 sucks the dropped steel ball and places it in place. The present invention realizes automatic compression deformation testing and rebound resilience testing of latex pillows, can test the rebound resilience of latex pillows under different deformations, provides data support for product performance analysis of latex pillows, and improves test efficiency and reliability.

[0021] like Figures 3 to 7 As shown, the following preferred technical solutions are provided: The compression deformation test assembly 1 includes a pressure plate 11, a guide rod group 12, a hydraulic push rod 13 and a fixed frame 14. The pressure plate 11 is installed on the guide rod group 12 through the lower pressure rod group 15. The hydraulic push rod 13 is installed on the fixed frame 14 and the output end is connected to the upper end of the lower pressure rod group 15. The guide rod group 12 is slidably installed on the fixed frame 14 through the rod seat 16. The lower pressure rod group 15 and the guide rod group 12 both pass through the rod seat 16. The rod seat 16 is fixedly installed on the fixed frame 14. The pressure plate 11 is facing the movable positioning mechanism 22.

[0022] The guide rod group 12 includes a guide rod 121 and a connecting plate 122. The connecting plate 122 is slidably installed on the lower pressure rod group 15. The connecting plate 122 and the pressure plate 11 are connected by a spring 123. The spring 123 is sleeved on the lower pressure rod group 15 and its two ends respectively abut the connecting plate 122 and the pressure plate 11.

[0023] Specifically, in order to test the compression deformation performance of the latex pillow, the present invention places the latex pillow on the mobile positioning mechanism 22 and is located below the pressure plate 11. The hydraulic push rod 13 pushes the guide rod group 12 and the lower pressure rod group 15 downward synchronously, so that the pressure plate 11 compresses the latex pillow downward. When the pressure plate 11 starts to compress the latex pillow, the hydraulic push rod 13 continues to push the guide rod 121 and the connecting plate 122, and the connecting plate 122 compresses the spring 123, so that the pressure of the pressure plate 11 on the latex pillow always maintains a stable output, and the compression deformation ability of the latex pillow is analyzed using data from the pressure sensors on the lower surface of the pressure plate 11 and the mobile positioning mechanism 22.

[0024] like Figures 3 to 7 As shown, the following preferred technical solutions are provided: The mobile positioning mechanism 22 includes a mobile seat 221, a guide rod group 222, a hydraulic push rod 223 and a mounting frame 224. The mobile seat 221 is installed on the mounting frame 224 and is opposite to the pressure plate 11 and the falling ball rebound detection module 21. The guide rod group 222 is located on both sides of the mobile seat 221. The hydraulic push rod 223 is installed on the mounting frame 224 and the output end is slidingly connected to the guide rod group 222 through the guide plate 225. The mobile seat 221 and the guide plate 225 are connected by a right-angle lever 226. The falling ball rebound detection module 21 is installed on the guide plate 225 and is opposite to the mobile seat 221.

[0025] The right-angle end of the right-angle lever 226 is hinged to the mounting frame 224 through a hinge seat 227, the front lever 2262 of the right-angle lever 226 is slidingly connected to the moving seat 221 through a connecting bolt 228, and the rear lever 2263 of the right-angle lever 226 is connected to the guide plate 225 through an abutment wheel 229 and an abutment foot rod 229.

[0026] The abutting foot rod 229 is fixedly mounted on both ends of the guide plate 225, and the right-angle lever 226 is connected to the hinge seat 227 through a torsion spring 220. One end of the torsion spring 220 is buckled on the hinge seat 227 and the other end is buckled on the front lever 2262 of the right-angle lever 226. A connecting groove 2261 is provided on the front lever 2262 of the right-angle lever 226, and a connecting bolt 228 is fixedly mounted on the end of the moving seat 221 and is slidably connected to the connecting groove 2261.

[0027] Specifically, in order to solve the technical problems of the position switching of the latex pillow between the compression deformation test assembly 1 and the falling ball rebound detection module 21 and the ability of the falling ball rebound detection module 21 to align with the latex pillow and approach the test position when the latex pillow is undergoing a rebound test, the present invention realizes the sliding of the latex pillow between the compression deformation test assembly 1 and the falling ball rebound detection module 21 by moving the moving seat 221 of the positioning mechanism 22. After the latex pillow completes a compression deformation test, the hydraulic push rod 223 pushes the guide plate 22 5 moves downward, and the guide plate 225 drives the contact foot rod 229 to move and press against the contact wheel and the rear lever 2263 of the right-angle lever 226, causing the front lever 2262 and the rear lever 2263 of the right-angle lever 226 to rotate. The front lever 2262 drives the connecting bolt 228 to slide in the connecting groove 2261 and causes the movable seat 221 to move downward toward the falling ball rebound detection module 21. When the guide plate 225 moves downward, it also synchronously drives the falling ball rebound detection module 21 to approach the moving latex pillow.

[0028] like Figure 5 As shown, the following preferred technical solutions are provided: The falling ball rebound detection module 21 includes a transparent tube 211 for easy observation and a lifting plate 212 with an adjustable height of the transparent tube 211. The transparent tube 211 is installed on the lifting plate 212. The lower end of the lifting plate 212 is provided with a proximity switch 213 and a sensor mounting part 214. The top of the transparent tube 211 is provided with an electromagnet module 215 and a ball cover 216. The transparent tube 211 and the ball cover 216 are both provided with a take-in and put-out port 217 for the steel ball suction mechanism 4 to suck the steel ball.

[0029] Specifically, in order to solve the technical problem of testing the resilience of a latex pillow, the present invention uses a falling ball rebound detection module 21 to complete the falling of a steel ball to impact the latex pillow and to sense and record the height of the steel ball rebound, uses a steel ball suction mechanism 4 to place the steel ball in a ball cover 216, and controls the falling of the steel ball through an electromagnet module 215. During the falling and rebounding process of the steel ball, a proximity switch 213 and a sensor are used to complete data collection and transmission.

[0030] like Figures 3 to 11 As shown, the following preferred technical solutions are provided: The steel ball suction mechanism 4 includes an electromagnet suction head 41, a lifting module 42 and a driving module 43. The electromagnet suction head 41 is slidably installed on the lifting module 42 through a suction head seat 44. The suction head seat 44 is installed on the upper end of the lifting module 42 through a movable rail 45 and a rail seat 46. The movable rail 45 is connected to the driving module 43 through a cam transmission module 1 47. The lifting module 42 is connected to the driving module 43 through a cam transmission module 2 48. The lifting module 42, the driving module 43, the cam transmission module 1 47 and the cam transmission module 2 48 are all fixedly installed on the workbench 3 through a mounting plate 49 and face the falling ball rebound detection module 21.

[0031] The driving module 43 drives the cam transmission module 1 47 and the cam transmission module 2 48 to move synchronously, thereby realizing the lifting and lowering movement of the electromagnet suction head 41 and the lifting module 42, as well as the forward and backward movement of the electromagnet suction head 41. The cam transmission module 1 47 drives the movable rail 45, the suction head seat 44, and the electromagnet suction head 41 to slide left and right on the rail seat 46, so that the electromagnet suction head 41 can approach the steel ball and extend into the access opening 217 of the transparent tube 211 and the ball cover 216. The use of the electromagnet suction head 41 to absorb the steel ball eliminates the need for staff to grasp the steel ball, solves the problem of the heavy and slippery steel ball being difficult to grasp, avoids the problem of the steel ball accidentally falling and injuring people and damaging equipment during the grasping process, and also improves the grasping efficiency and testing efficiency.

[0032] The cam transmission module 47 includes a cam 471, an abutting rotating rod 472 and a guide rail 473. The cam 471 is installed on one end of the transmission shaft 431 of the driving module 43. One end of the abutting rotating rod 472 is rotatably installed on one side of the mounting plate 49 through a hinge 474. The other end of the abutting rotating rod 472 is slidingly connected to the guide rail 473 through a guide wheel 475. The guide rail 473 is fixedly connected to the movable rail 45. The cam 471 and the abutting rotating rod 472 are abutted by a abutting wheel 476. The abutting rotating rod 472 and the mounting plate 49 are connected by a tension spring 477.

[0033] The drive module 43 drives the transmission shaft 431 and cam 1 471 to rotate, utilizing the structural features of cam 1 471 to achieve abutment between cam 1 471 and abutment lever 1 472. As cam 1 471 rotates, abutment lever 1 472 is driven to swing left and right around hinge 1 474, thereby enabling abutment lever 1 472 to drive the guide wheel to slide on the guide rail 473. The left and right sliding of the guide rail 473 and the movable rail 45 on the rail seat 46 enables the left and right sliding of the suction head seat 44 and the electromagnet suction head 41. As cam 1 471 rotates, cam transmission module 2 48 also moves synchronously, achieving the lifting and lowering motion of the lifting module 42. The coordination between cam transmission module 2 48 and cam transmission module 1 47 allows the electromagnet suction head 41 to complete a left and right sliding motion at both the lowest and highest points of the lifting module 42.

[0034] The cam transmission module 48 includes a cam 481 and a contact rotating rod 482. The cam 481 is fixedly mounted on the other end of the transmission shaft 431 of the driving module 43. One end of the contact rotating rod 482 is rotatably mounted on the mounting plate 49 through a hinge 483. The contact rotating rod 482 is abutted with the cam 481 through a contact wheel 484. The other end of the contact rotating rod 482 is slidingly connected to the lifting module 42. The lifting module 42 includes a lifting seat 421 and a lifting rail group 422. The lifting seat 421 is slidingly connected to the lifting rail group 422. The lifting rail group 422 is mounted on the mounting plate 49. The other end of the contact rotating rod 482 is slidingly connected to the lifting seat 421 through a guide wheel 485. The lifting seat 421 and the mounting plate 49 are connected through a tension spring 486. The rail seat 46 is fixedly mounted on the upper end of the lifting seat 421.

[0035] In order to achieve the lifting and lowering of the rail seat 46, the suction head seat 44 and the electromagnet suction head 41, the present invention drives the transmission shaft 431 to rotate through the driving module 43, and the transmission shaft 431 drives the cam 2 481 to move. The structure of the cam 2 481 is utilized to achieve the abutment between the cam 2 481 and the abutment rotating rod 2 482 and the up and down swinging of the abutment rotating rod 2 482 around the hinge rod 2 483. While the abutment rotating rod 2 482 swings up and down, the lifting and sliding of the lifting seat 421 on the lifting rail group 422 is achieved through the guide wheel 2 485 and the lifting seat 421. By utilizing the different structures and synchronous rotation cooperation of cam 1 471 and cam 2 481, the electromagnetic suction head 41 slides left and right once when it descends to the lowest point. At this time, the electromagnetic suction head 41 extends into the take-out opening 217 of the transparent tube 211 to absorb the steel ball and retract; when the electromagnetic suction head 41 rises to the highest point, the electromagnetic suction head 41 slides left and right again under the action of cam 1 471 and abutting rotating rod 1 472, and the electromagnetic suction head 41 extends into the take-out opening 217 of the ball cover 216 to release the steel ball and retract.
