[0002] Spring mattress is a modern commonly used mattress with better performance, and the core of the mattress is composed of springs. The mattress has the advantages of good elasticity, better support, strong air permeability, durability, etc.

[0003] In order to ensure the quality of the spring mattress, the deformation life of the spring to be used needs to be tested before the mattress production. The current spring testing generally places the spring in a pressure testing machine, and continuously applies pressure to the spring through the pressure testing machine. After the test is completed, the deformation of the spring is measured to ensure the service life of the spring. However, since the force direction of the spring is different in actual use, the above method can only apply force in a single direction to the spring, and cannot accurately measure the spring deformation life in actual use, and cannot measure the influence of different forces on the spring deformation when the force direction does not change.

DETAILED DESCRIPTION

When an element is considered to be "connected" to another element, it can be directly connected to another element or can have a middle element. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation.

[0039] In the embodiments of the present application, a spring deformation life multi-directional monitoring method for mattress production comprises the following steps:

[0040] Step one: before formal detection of compression spring, the spring is compressed to test load, and when the test load is greater than the compression load, the compression load can be used as the test load;

[0041] Step two: the spring is placed in the spring detection device, and under the action of the spring detection device, the deformation amount of the spring under the same stress angle and different forces is detected, and the deformation amount of the spring under different stress angles and the same force is detected;

[0042] Step three: the deformation amount of the spring after the test is measured by an infrared measuring instrument, and the deformation amount is recorded, so as to calculate the deformation life of the spring.

[0043] Please refer to Figures 1-11The application discloses a spring deformation life multi-direction monitoring method for mattress production.

[0044] The base 1 is provided with a fixed plate 4, and the fixed plate 4 is provided with symmetrical horizontal plates 33.

[0045] Please refer to Figures 1-6 The test spring 18 is arranged on the base 1 in a symmetrical mode, and the base 1 is provided with a control mechanism connected with the test spring 18, the control mechanism can drive the test spring 18 to swing by a certain angle, the control mechanism comprises a guide rod 15 fixedly installed on the base 1, a guide sleeve 16 movably installed on the guide rod 15, a movable plate 17 fixedly installed on the guide sleeve 16 and connected with the test spring 18, a limiting rod fixedly installed on the guide rod 15 and a limiting groove formed in the guide sleeve 16 and engaged with the limiting rod, and the movable plate 17 is matched with the guide assembly; wherein the base 1 is provided with symmetrical No. 23 motors, the base 1 is further provided with an angle control assembly connected with the output shaft of the No. 23 motor and connected with the test spring 18, the angle control assembly comprises a rotating disc 20 rotatably installed on the base 1 and connected with the output shaft of the No. 23 motor, a clamping groove 22 formed in the rotating disc 20, a movable disc 19 slidably installed in the clamping groove 22, an arc-shaped protrusion 21 fixedly installed on the rotating disc 20 and abutting against the movable disc 19, and the movable disc 19 is connected with the test spring 18.

[0046] It should be noted that when the human body lies on the mattress, the force applied to the spring in the mattress is different, and the direction of the pressure applied by different parts of the human body to the spring is offset, so it is necessary to adjust the stress angle of the test spring 18. In the initial state, the heights of the two rotating discs 20 are different, and the two arc protrusions 21 are located in the upper and lower symmetrical positions. At this time, the two movable discs 19 are located at the same center axis position, and the two sections of the test spring 18 are respectively hooked on the movable disc 19 and the movable plate 17. At this time, the test spring 18 is in a vertical position with the movable disc 19 and the movable plate 17. When the guide assembly moves, it drives the movable plate 17 to move towards the movable disc 19, and drives the guide sleeve 16 to move along the length direction of the guide rod 15. Since the limiting groove and the limiting rod are engaged, the guide sleeve 16 will not be offset during movement, so as to ensure that the movable plate 17 moves along the length direction of the guide rod 15. At this time, the test spring 18 is only subjected to a force in the spiral direction thereof. When the guide assembly no longer acts on the movable plate 17, the test spring 18 is elastically released and drives the movable plate 17 to move towards the initial position. The deformation amount of the test spring 18 relative to the initial state can be measured by an infrared sensor. When it is necessary to measure the deformation amount of the test spring 18 subjected to a force in other directions, the No. 2 motor 23 works to drive the rotating disc 20 to rotate, thereby driving the arc-shaped protrusion 21 to rotate. Under the action of the arc-shaped protrusion 21, the movable disc 19 is offset by a certain angle compared with the initial position. The test spring 18 is no longer in a vertical position with the movable plate 17 and the movable disc 19. At this time, the guide assembly acts on the movable plate 17 again, and the test spring 18 will be subjected to a force in an inclined direction. When the guide assembly is separated from the movable plate 17, the deformation amount of the test spring 18 can be measured. The above steps are repeated to obtain the deformation amounts of the test spring 18 subjected to forces in different directions.

[0047] Preferably, since the rotating discs 20 are arranged at different heights, when the rotating discs 20 rotate, the two movable discs 19 are offset in opposite directions. The movable disc 19 in the rotating disc 20 at the lower position is offset towards the lower position, and the movable disc 19 in the rotating disc 20 at the higher position is offset towards the upper position. The offset positions of the test springs 18 are opposite, so that the deformation amounts of the test springs 18 in two directions are obtained at one time, and the test process is accelerated.

[0048] Please refer to Figures 1-5 , Figures 9-11The guiding assembly is arranged on the fixed plate 4 and cooperates with the regulating mechanism, and comprises a guide rail 5 fixedly arranged on the fixed plate 4, a sliding plate 6 slidingly arranged on the guide rail 5, a connecting plate 13 fixedly arranged on the sliding plate 6 in a symmetrical manner, a limiting wheel 14 fixedly arranged on the connecting plate 13 and cooperating with the movable plate 17, and the connecting plate 13 is connected with the adjusting assembly, and the sliding plate 6 is provided with a straight slot and is connected with the driving assembly and the limiting assembly.

[0049] Further, in the initial state, the sliding plate 6 is located at the middle position of the guide rail 5, and at this time, the limiting wheel 14 is separated from the movable plate 17, when the driving assembly works, the sliding plate 6 is driven to move along the length direction of the guide rail 5, so as to drive the limiting wheel 14 to move through the connecting plate 13, when the limiting wheel 14 moves to the abutting position of the movable plate 17, the movable plate 17 is driven to apply a force to the test spring 18, when the limiting wheel 14 moves to the end of the stroke, at this time, the sliding plate 6 moves towards the other end of the guide rail 5, so that the limiting wheel 14 is separated from the movable plate 17 and drives the other limiting wheel 14 to move to the abutting position of the other movable plate 17, so as to act on the other test spring 18, under the action of the driving assembly, the sliding plate 6 reciprocatingly slides on the guide rail 5, so as to continuously test the test spring 18.

[0050] Please refer to Figure 1 、 Figures 3-5 、 Figures 8-11 The base 1 is provided with a driving assembly connected with the guiding assembly, the driving assembly can drive the regulating mechanism to move through the guiding assembly, so as to apply a force to the test spring 18, and the driving assembly comprises a first motor 2 fixedly arranged on the base 1, a vortex disc 3 rotatably arranged on the base 1 and connected with the output shaft of the first motor 2, a hinged plate 7 hingedly arranged in the straight slot, and an inclined block 8 fixedly arranged on the hinged plate 7 in a symmetrical manner and cooperating with the vortex disc 3, the inclined block 8 is connected with the supporting assembly, and the hinged plate 7 is connected with the limiting assembly.

[0051] Further, the vortex disc 3 is disc-shaped and provided with protrusions in a vortex shape, and the inclined blocks 8 are triangularly arranged, in the initial state, the sliding plate 6 is horizontal, the hinged plate 7 is deflected by a certain angle, so that one of the inclined blocks 8 is located in the vortex disc 3 and is clamped with the recessed position of the vortex disc 3, and the other inclined block 8 is located in the position separated from the vortex disc 3, under the action of the limiting assembly, the angle of the hinged plate 7 is no longer changed, at this time, the first motor 2 works to drive the vortex disc 3 to rotate, thereby driving the inclined block 8 in the vortex disc 3 to move, so that the hinged plate 7 moves, and the sliding plate 6 moves along the length direction of the guide rail 5, taking the center point of the vortex disc 3 as the center position, the sliding plate 6 moves towards the direction of the inclined block 8 clamped with the vortex disc 3, when the inclined block 8 in the vortex disc 3 moves to the cooperating position with the supporting assembly, under the action of the supporting assembly, the inclined block 8 is separated from the vortex disc 3 and drives the hinged plate 7 to rotate, so that the other inclined block 8 enters the vortex disc 3, at this time, the vortex disc 3 continues to rotate, under the action of the other inclined block 8, the sliding plate 6 moves towards the other end of the guide rail 5, thereby realizing the effect of reciprocating movement of the sliding plate 6 on the guide rail 5.

[0052] Please refer to Figures 9-11 The base 1 is further provided with a limiting assembly connected with the guide assembly and the driving assembly, the limiting assembly comprises a fixed sleeve 10 fixedly installed on the sliding plate 6, an active rod 11 movably installed in the fixed sleeve 10, a supporting spring 12 fixed in the fixed sleeve 10 and abutting against the active rod 11, and a triangular block 9 fixed on the hinged plate 7 and abutting against the active rod 11.

[0053] Further, the active rod 11 is triangularly arranged towards one side of the base 1, and the triangular block 9 is located in the middle position of the hinged plate 7, when the hinged plate 7 is parallel to the sliding plate 6, the triangular block 9 is located directly below the active rod 11, in the initial state, the hinged plate 7 is deflected by a certain angle, so that the triangular block 9 is deflected to one side of the active rod 11, the supporting spring 12 is in the compressed state, so that the active rod 11 is located at the end of the stroke towards the base 1, the end of the active rod 11 towards the triangular block 9 cooperates with the inclined surface of the triangular block 9 and limits the position of the triangular block 9, so as to ensure that one of the inclined blocks 8 does not separate from the vortex disc 3, when the inclined block 8 in the vortex disc 3 separates from the vortex disc 3, the hinged plate 7 is driven to rotate to the symmetrical position, thereby driving the triangular block 9 to deflect to the other side of the active rod 11, and the triangular block 9 also drives the active rod 11 to move away from the base 1 when moving, so that the supporting spring 12 is compressed, when the deflection of the triangular block 9 is completed, the supporting spring 12 is elastically released, so that the active rod 11 abuts against the other inclined surface of the triangular block 9, thereby fixing the hinged plate 7.

[0054] Please refer to Figures 8-10Support assembly arranged on the base 1 and connected with the driving assembly, the support assembly comprises a plurality of groups of through grooves 24 arranged equidistantly on the vortex disc 3, a fixing block 27 is fixed in the through groove 24, a support rod 25 abutting against the fixing block 27 is slidingly installed in the through groove 24, a fixing wheel 26 is fixed on the support rod 25, the fixing wheel 26 is connected with the adjusting assembly, and the support rod 25 cooperates with the tilt block 8.

[0055] Further, when the sliding plate 6 is located at the middle position of the guide rail 5, one of the tilt blocks 8 is located in the vortex disc 3, a plurality of groups of the through grooves 24 are arranged along the length direction of the guide rail 5 and are located in the recessed positions of the vortex disc 3, the through groove 24 close to the center position of the vortex disc 3 is located at a different position from the tilt block 8, and under the action of gravity, the support rod 25 is located at the end of the stroke towards the base 1 and abuts against the fixing block 27, and the side of the support rod 25 away from the base 1 is located at the same horizontal plane as the side of the through groove 24 away from the base 1, so that the movement of the tilt block 8 is not affected. In order to adjust the movement direction of the sliding plate 6 and ensure that the sliding plate 6 can reciprocate, the hinged plate 7 needs to be controlled to intermittently deflect by a certain angle, so that the two tilt blocks 8 are alternately matched with the vortex disc 3. Under the action of the adjusting mechanism, one of the fixing wheels 26 is driven to move away from the base 1, and the support rod 25 connected with the fixing wheel 26 is also driven to move. At this time, the vortex disc 3 rotates to drive the tilt block 8 to move, and the vortex disc 3 also drives the support rod 25 to rotate. When the vortex disc 3 rotates by one circle, the adjusting mechanism cooperates with the fixing wheel 26 to drive the support rod 25 to move, and the vortex disc 3 continues to rotate to make the support rod 25 cooperate with the tilt block 8, so as to drive the hinged plate 7 on which the tilt block 8 is fixed to deflect by a certain angle, so that the other tilt block 8 enters the vortex disc 3. At this time, the sliding plate 6 moves towards the other direction of the guide rail 5. When the vortex disc 3 rotates by one circle, the tilt block 8 will move to the same horizontal position as the support rod 25. Therefore, by adjusting the cooperation between different support rods 25 and tilt blocks 8, the track of the sliding plate 6 can be adjusted.

[0056] Please refer to Figures 1-5 , Figures 7-10The horizontal plate 33 is provided with an adjusting mechanism connected with the support assembly, the adjusting mechanism comprises an adjusting assembly and a limiting block 37, the adjusting assembly can move when the guide assembly moves and drives the support assembly to move through the limiting block 37, the adjusting assembly comprises a ratchet plate 28 fixedly installed on the connecting plate 13, a rotating rod 29 rotatably installed on the fixed plate 4, a ratchet wheel 30 fixedly installed on the rotating rod 29 and engaged with the ratchet plate 28, the rotating rod 29 is fixed with a winding roller 31, the horizontal plate 33 is provided with a sliding structure connected with the winding roller 31, the sliding structure is fixedly connected with the limiting block 37, wherein the sliding structure comprises a track 35 fixedly installed on the horizontal plate 33, a sliding block 36 slidably installed on the track 35, a guide wheel 34 rotatably installed on the horizontal plate 33, the winding roller 31 is wound with a steel wire 32 sleeved on the guide wheel 34 and connected with the sliding block 36, and the sliding block 36 is fixedly connected with the limiting block 37.

[0057] Finally, in order to adjust the force applied to the test spring 18 each time, it is necessary to adjust the stroke amount of the reciprocating movement of the sliding plate 6. In the initial state, the ratchet plate 28 is in engagement with the ratchet wheel 30, the steel wire 32 is in a released state, the sliding block 36 is located at the stroke end away from the guide wheel 34 on one side of the track 35, and the limiting block 37 is in abutment with the fixed wheel 26 towards the center of the vortex disc 3, so that the support rod 25 connected with the fixed wheel 26 can cooperate with the inclined block 8. When the vortex disc 3 rotates, the support rod 25 is driven to move, so that the fixed wheel 26 is separated from the limiting block 37. The vortex disc 3 also drives the connecting plate 13 to move, thereby driving the ratchet plate 28 to move. At this time, the ratchet wheel 30 does not rotate, and the vortex disc 3 continues to rotate. When the fixed wheel 26 moves to the position cooperating with the limiting block 37 again, the support rod 25 is driven to move. At this time, the inclined block 8 just moves to the position abutting against the support rod 25, thereby driving the inclined block 8 to move, so that the hinged plate 7 rotates to drive the other inclined block 8 into the vortex disc 3. At this time, the sliding plate 6 moves towards the other end of the guide rail 5, so that the ratchet plate 28 moves towards the initial position and drives the ratchet wheel 30 to rotate, thereby driving the rotating rod 29 to rotate and driving the winding roller 31 to rotate. The winding roller 31 will wind the steel wire 32, thereby pulling the sliding block 36 to slide on the track 35 through the steel wire 32, and driving the limiting block 37 to move. When the ratchet plate 28 moves to the position separated from the ratchet wheel 30, the limiting block 37 just moves to the position cooperating with the second fixed wheel 26. Therefore, the next time the inclined block 8 cooperates with the support rod 25, the sliding plate 6 needs to increase the stroke on the guide rail 5, thereby realizing the effect that the size of the force applied to the test spring 18 is continuously increased.

[0058] Preferably, when the reciprocating stroke of the sliding plate 6 is the shortest, the ratchet plate 28 will be separated from the ratchet wheel 30 when it reaches the end of the stroke, thereby ensuring that the amount of rotation of the ratchet wheel 30 does not change when the stroke of the sliding plate 6 increases, so that the stroke of the sliding block 36 does not change each time, ensuring that the limiting block 37 cooperates with the fixed wheel 26 in turn.

[0059] Taking the embodiment combining all the features described in this application as an example, when a person lies on the mattress, the force applied to the springs inside the mattress is different, and the direction of the pressure applied to the springs by different parts of the body is offset. Therefore, it is necessary to measure the influence of different forces on the deformation of the spring under the same force angle, and the influence of the same force on the deformation of the spring under different force angles. In the initial state, the two turntables 20 are at different heights, and the two arc-shaped protrusions 21 are located in symmetrical positions. At this time, the two movable discs 19 are located at the same central axis position. The two ends of the test spring 18 are hooked on the movable disc 19 and the movable plate 17 respectively. At this time, the test spring 18 is in a vertical position with the movable disc 19 and the movable plate 17, and the hinge plate 7 is biased. Rotate at a certain angle so that one of the tilting blocks 8 is located inside the volute disk 3 and engages with the recessed position of the volute disk 3, while the other tilting block 8 is located in the separated position from the volute disk 3. The support spring 12 is in a compressed state, so that the movable rod 11 is at the end of its stroke towards the base 1. The end of the movable rod 11 facing the triangular block 9 engages with the inclined surface of the triangular block 9 and restricts the position of the triangular block 9, ensuring that one of the tilting blocks 8 will not disengage from the volute disk 3. The sliding block 36 is located at the end of its stroke on the side of the track 35 away from the guide wheel 34. At this time, the limiting block 37 abuts against the fixed wheel 26 facing the center of the volute disk 3, so that the support rod 25 connected to the fixed wheel 26 can engage with the tilting block 8. At this time, the first motor 2 works, driving the volute disk 3 to rotate. This causes the inclined block 8 located inside the volute disk 3 to move, which in turn causes the hinge plate 7 to move, allowing the sliding plate 6 to move along the length of the guide rail 5. With the center point of the volute disk 3 as the center position, the sliding plate 6 moves towards the inclined block 8 that engages with the volute disk 3, thereby driving the limiting wheel 14 to move via the connecting plate 13. When the limiting wheel 14 moves to the position where it abuts against the movable plate 17, it drives the movable plate 17 to move towards the movable disk 19, and drives the guide sleeve 16 to move along the length of the guide rod 15. Since the limiting groove engages with the limiting rod, it ensures that the guide sleeve 16 will not deviate during movement, thus ensuring that the movable plate 17 moves along the length of the guide rod 15. At this time, the test spring 18 is only subjected to force along its helical direction. When it is necessary to measure the deformation of the test spring 18 under forces acting in other directions, motor 23 operates, driving turntable 20 to rotate, which in turn drives the arc-shaped protrusion 21 to rotate. Under the action of the arc-shaped protrusion 21, the movable disk 19 shifts at a certain angle relative to its initial position. The test spring 18 is no longer in a position perpendicular to the movable plate 17 and the movable disk 19, thus changing the direction of the force acting on the test spring 18, thereby obtaining the deformation of the test spring 18 under forces acting in different directions. When the volute 3 rotates, it drives the support rod 25 to move, causing the fixed wheel 26 to separate from the limit block 37. The volute 3 also drives the connecting plate 13 to move, thereby driving the ratchet plate 28 to move. At this time, the ratchet 30 does not rotate, and the volute 3 continues to rotate.When the fixed wheel 26 moves to the position of cooperating with the limiting block 37 again, the driving support rod 25 is driven to move, at this time, the inclined block 8 just moves to the position of abutting against the support rod 25, thereby driving the inclined block 8 to move, so that the hinged plate 7 rotates to drive another inclined block 8 to enter the spiral disc 3, at this time, the sliding plate 6 moves towards the other end of the guide rail 5, so that the ratchet plate 28 moves towards the initial position, and drives the ratchet wheel 30 to rotate, thereby driving the rotating rod 29 to rotate, and driving the winding roller 31 to rotate, the winding roller 31 will wind the steel wire 32, thereby pulling the sliding block 36 to slide on the track 35 through the steel wire 32, and driving the limiting block 37 to move, when the ratchet plate 28 moves to the position of separating from the ratchet wheel 30, the limiting block 37 just moves to the position of cooperating with the second fixed wheel 26, therefore, when the inclined block 8 cooperates with the support rod 25 next time, the sliding plate 6 needs to increase the stroke of moving on the guide rail 5, thereby realizing the effect of increasing the size of the force applied to the test spring 18 constantly.
