[0049] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. It is to be understood that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application. It should also be noted that, for ease of description, only some structures related to the present application are shown in the accompanying drawings, rather than all structures. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0050] The terms "including" and "having" and any variations thereof in this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device comprising a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products or devices.

[0051] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0052] like Figures 1 to 5 As shown, a mattress rolling tester corresponding to a preferred embodiment of the utility model includes a base 1, a rolling device 2, an extrusion device 3 and a force sensor 313.

[0053] The base 1 is provided with a support plane 11 for placing the mattress 10 , and the base 1 is placed horizontally on the ground. For example, height-adjustable support legs can be provided on the surface of the base 1 facing the ground to ensure that the base 1 is placed horizontally.

[0054] The rolling device 2 is located above the base 1 and is used to roll the upper surface of the mattress 10 so as to perform a durability test on the mattress 10 .

[0055] The squeezing device 3 includes a blocking seat 30 and a side loader 31. The blocking seat 30 and the side loader 31 are both connected to the base 1 and are respectively located on both sides of the mattress 10. For example, they can be fixedly connected to the base 1 by bolts or welding. The side loader 31 applies a squeezing force to the mattress 10, so that the mattress 10 is squeezed between the blocking seat 30 and the side loader 31.

[0056] The force sensor 313 is used to measure the squeezing force applied by the side loader 31 to the mattress 10, so that the squeezing force can accurately reach the required size, such as 15N required by the standard.

[0057] The number of extrusion devices 3 can be set as needed. For example, when testing according to the standard, it is necessary to measure the length of three specified positions and the width of three specified positions. Figure 1 and Figure 2 As shown, the mattress rolling tester includes three squeezing devices 3 arranged at intervals along the length and width directions of the mattress 10, so as to improve the accuracy of the measurement. Furthermore, squeezing devices 3 are arranged at the four corners of the mattress 10. When measuring the size of the mattress 10, the side loader 31 applies squeezing force to the mattress 10 until the force sensor 313 reaches the required value, and then the size of the mattress 10 is measured by a steel ruler. It is understandable that in other standards with different test requirements or in other cases, the number and position of the squeezing devices 3 can be adjusted as needed.

[0058] Since the mattress rolling test machine is provided with a rolling device 2, a blocking seat 30 and a side loader 31, it is not only capable of conducting a durability test on the mattress 10, but also capable of measuring the length and width dimensions of the mattress 10 under a required extrusion force. The functions of the mattress rolling test machine are more diversified, and durability testing and dimension measurement can be completed on one mattress rolling test machine.

[0059] In some embodiments, Figure 6 As shown, the blocking seat 30 includes a baffle 300 vertically arranged with respect to the supporting plane 11, and the baffle 300 is used to abut against the mattress 10; the baffle 300 can be directly connected to the base 1, and in order to facilitate the installation of the baffle 300, the blocking seat 30 also includes a first bottom plate 301 vertically connected with the baffle 300, and is connected to the base 1 through the first bottom plate 301.

[0060] like Figure 4 and Figure 5As shown, the side loader 31 includes a pressing plate 310 vertically arranged with respect to the support plane 11, a fixing seat 311 fixedly connected with the base 1, and a linear transmission mechanism 312 connected between the pressing plate 310 and the fixing seat 311, and the linear transmission mechanism 312 is used to drive the pressing plate 310 to move horizontally. The fixing seat 311 includes a vertical plate 3110 arranged opposite to and parallel to the pressing plate 310, and a second bottom plate 3111 vertically arranged with respect to the vertical plate 3110 and fixed with the base 1.

[0061] Optionally, the blocking seat 30 and the side loader 31 are both detachably connected to the base 1. Figure 1 and Figure 2 In the illustrated embodiment, the first bottom plate 301 and the second bottom plate 3111 are fixedly connected to the base 1 by bolts, so that the extrusion device 3 can be easily disassembled.

[0062] Furthermore, if Figures 7 to 9 As shown, the position of the extrusion device 3 on the base 1 is adjustable, for example, a long hole 3010 extending along the side of the mattress 10 can be set on the first bottom plate 301 and the second bottom plate 3111, and a bolt is passed through the long hole 3010 to be fixedly connected with the base 1. After loosening the bolt, the extrusion device 3 can be adjusted along the side of the mattress 10. Preferably, the direction of adjusting the position of the extrusion device 3 is parallel to the side of the mattress 10 corresponding to it, for example, the adjustment direction of the extrusion device 3 that extrudes the long side of the mattress 10 is parallel to the long side of the mattress 10.

[0063] like Figure 8 and Fig. 9 As shown, the baffle 300 and the first bottom plate 301 as well as the vertical plate 3110 and the second bottom plate 3111 are vertically connected, for example, they can be obtained by an integral molding method. In order to improve the stability of the connection, a rib plate 302 is provided between the baffle 300 and the first bottom plate 301 and between the vertical plate 3110 and the second bottom plate 3111; Figure 8 and Fig. 9 In the illustrated embodiment, the ribs 302 are disposed on both sides of the baffle 300 and the first bottom plate 301 and on both sides of the vertical plate 3110 and the second bottom plate 3111 , and may be fixedly connected by welding, for example.

[0064] The baffle 300 of the blocking seat 30 and the pressing plate 310 of the side loader 31 are arranged correspondingly to cooperate in squeezing the two sides of the mattress 10. Optionally, the width of the baffle 300 and the pressing plate 310 is 300 mm and the length is 500 mm; the baffle 300 abuts against one side of the mattress 10, and the pressing plate 310 abuts against the other side of the mattress 10. The distance between the baffle 300 and the pressing plate 310 can be adjusted by the linear transmission mechanism 312, so that the mattress 10 is subjected to the squeezing force, and the force sensor 313 can display the magnitude of the squeezing force on the mattress 10, thereby meeting the requirement in the standard that the mattress 10 needs to measure the length and width under the action of 15N force.

[0065] like Figure 4 and Figure 5 As shown, the linear transmission mechanism 312 includes a transmission shaft 3120 threadedly connected to the fixing seat 311, and one end of the transmission shaft 3120 is connected to (e.g., abutted against) the pressing plate 310, thereby driving the pressing plate 310 to move to adjust the distance between the baffle 300 and the pressing plate 310, so that the mattress 10 is subjected to a squeezing force; that is, by rotating the transmission shaft 3120, the pressing plate 310 applies an external force to the mattress 10. The transmission shaft 3120 can at least drive the pressing plate 310 to move in a direction away from the vertical plate 3110.

[0066] In one embodiment, if Figure 4 and Figure 5 As shown, the force sensor 313 is disposed at the end of the transmission shaft 3120 and can abut against the pressure plate 310. When the transmission shaft 3120 with the force sensor 313 contacts the pressure plate 310, the force sensor 313 can sense the extrusion force. Fig.10 and Fig.11 As shown, the force sensor 313 is disposed on the pressure plate 310 and is disposed corresponding to the transmission shaft 3120. When the transmission shaft 3120 moves to contact with the force sensor 313, the force sensor 313 can sense the extrusion force.

[0067] It is understandable that in other embodiments, the force sensor 313 may also be disposed at other locations.

[0068] In some embodiments, Fig.12 As shown, the transmission shaft 3120 can be directly connected to the threaded hole on the vertical plate 3110 to achieve threaded connection. Figure 5 , Fig.10 and Fig.11 As shown, the linear transmission mechanism 312 includes a nut 3121 connected to the vertical plate 3110; optionally, the transmission shaft 3120 is a ball screw adapted to the nut 3121, and the transmission shaft 3120 is moved by means of a screw drive, so that the transmission shaft 3120 can be moved more smoothly.

[0069] like Fig.11 As shown, the linear transmission mechanism 312 also includes a hand wheel 3122 connected to the transmission shaft 3120. The hand wheel 3122 drives the transmission shaft 3120 to rotate, thereby facilitating the user to rotate the transmission shaft 3120 and improving the measurement efficiency.

[0070] In one embodiment, if Fig.13 and Fig.14As shown, the linear transmission mechanism 312 includes a convex plate 3124 connected to the transmission shaft 3120, and the linear transmission mechanism 312 also includes a connecting plate 3125 connected to the pressure plate 310, the connecting plate 3125 is provided with a through hole, the transmission shaft 3120 is inserted into the connecting plate 3125, and the convex plate 3124 is located between the connecting plate 3125 and the pressure plate 310, when the transmission shaft 3120 moves in a direction away from the pressure plate 310, the convex plate 3124 abuts against the connecting plate 3125, when the mattress 10 completes the length or width measurement, the pressure plate 310 can be separated from the mattress 10 by rotating the transmission shaft 3120, and a certain space is formed between the pressure plate 310 and the mattress 10, which is convenient for removing the mattress 10 or performing a rolling test, thereby further improving the test efficiency.

[0071] The linear transmission mechanism 312 can be automatic in addition to manual. Fig.15 and Fig.16 As shown, the linear transmission mechanism 312 is an electric linear drive, which includes a body 3126 connected to the fixing seat 311 and a driving shaft 3127 connected to the body 3126, and the driving shaft 3127 performs telescopic movement under the drive of the body 3126. Optionally, in order to facilitate the separation of the pressing plate 310 from the mattress 10 after the measurement of the mattress 10 is completed, a convex plate 3124 is provided on the driving shaft 3127, and a connecting plate 3125 is provided on the pressing plate 310.

[0072] In one embodiment, if Fig.15 As shown, the force sensor 313 is disposed at the end of the driving shaft 3127 and is capable of abutting against the pressure plate 310 .

[0073] In another embodiment, if Fig.16 As shown, the force sensor 313 is disposed on the pressure plate 310 and is arranged corresponding to the driving shaft 3127.

[0074] In order to ensure that the pressing plate 310 can move more accurately along a straight line, the pressing plate 310 is slidably coupled to the fixing seat 311 , and the moving direction of the pressing plate 310 is perpendicular to the surface of the pressing plate 310 facing the mattress 10 .

[0075] In one embodiment, if Figure 4 and Fig.17 As shown, the side loader 31 includes a linear bearing 314 connected to a fixing seat 311 and a guide shaft 315 matched in the linear bearing 314. The guide shaft 315 is connected to the pressing plate 310, and the linear bearing 314 and the guide shaft 315 limit the movement of the pressing plate 310. The pressing plate 310 is provided with a fixing member 318 corresponding to the linear bearing 314. The fixing member 318 and the pressing plate 310 can be connected and fixed by bolts or welding, for example. One end of the guide shaft 315 is fixedly connected to the fixing member 318.

[0076] In another embodiment, if Fig.18 and Fig.19 As shown, the side loader 31 includes a slide rail 316 connected to the support plane and a slide table 317 adapted to the slide rail 316, and the pressing plate 310 is connected to the slide table 317, and the sliding connection between the side loader 31 and the fixing seat 311 is realized through the slide rail 316 and the slide table 317. The design of the slide rail 316 and the slide table 317 can not only facilitate the movement of the pressing plate 310, but also play a role in limiting the movement of the pressing plate 310.

[0077] Furthermore, in order for the pressing plate 310 to be close to the supporting plane 11 and close to the mattress 10, the pressing plate 310 should be lowered as much as possible. Therefore, a mounting hole 3100 and a mounting plate 3101 vertically connected to the pressing plate 310 are provided on the side of the pressing plate 310 facing the supporting plane 11. The mounting plate 3101 is arranged on the side of the pressing plate 310 facing away from the mattress 10. The slide 317 is arranged in the mounting hole 310. The end face of one side of the slide 317 coincides with the surface of the pressing plate 310 facing the mattress 10. The slide 317 and the mounting plate 3101 are connected and fixed, for example, by bolts or welding.

[0078] The structure of the rolling device 2 can refer to the structure of the rolling device of the existing mattress roller test machine. Figure 1 and Fig. 20 As shown, the rolling device 2 includes a roller assembly 20, a first linear drive (not shown) for driving the roller assembly 20 to make horizontal linear motion, and a second linear drive 22 for driving the roller assembly 20 to make vertical motion. The roller assembly 20 includes a roller frame 200 and a roller 201 rotatably connected to the roller frame 200. During the test, the first linear drive moves the roller assembly 20 to one end of the mattress 10, the second linear drive 22 drives the roller assembly 20 to move downward to contact the mattress 10 and apply force to the mattress 10, and then the first linear drive drives the roller assembly 20 to move along the mattress 10 for testing.

[0079] The first linear drive preferably includes a belt drive mechanism, a chain drive mechanism, etc., and the second linear drive 22 is preferably an electric cylinder, a pneumatic cylinder, a hydraulic cylinder, etc.

[0080] The above are only specific implementations of the present invention, and any improvements made based on the concept of the present invention are considered to be within the protection scope of the present invention.
