Description

Technical Field

[0001] The present invention relates to the technical field of load force detection of EPS foam boards, and particularly to a load force detection device for EPS foam boards. Background Art

[0002] EPS foam board, also known as polystyrene foam board, is a white object formed by heating expandable polystyrene beads containing volatile liquid foaming agents in a mold after pre-expansion by heating. It has the structural characteristics of fine closed pores. After the EPS foam board is produced, it needs to be subjected to load force detection, that is, a certain pressure is applied to the foam board, and then the deformation degree and damage degree of the foam board are observed to see if it meets the standard requirements.

[0003] Currently, the load force detection of EPS foam boards is mostly manually operated. Workers place the EPS foam boards on the detection table one by one for detection. The manual feeding efficiency is relatively low, which will reduce the test efficiency and increase the labor intensity of workers. In addition, some foam boards will be damaged during the pressure detection process to produce foam particles, and the foam particles are relatively light. It is inconvenient to clean up later when they are scattered to other places. It not only affects the detection of foam boards, but also brings inconvenience to workers when sticking to their bodies.

Specific embodiments

[0028] Refer to Figure 1-8, a load force detection device for EPS foam board, including a base 1, the upper end of the base 1 is fixedly connected to a mounting frame 2, the mounting frame 2 is U-shaped, the upper end of the mounting frame 2 is fixedly connected to a hydraulic cylinder 3, the movable end of the hydraulic cylinder 3 passes through the top of the mounting frame 2 and is fixedly connected to a pressure plate 4, the upper end of the base 1 is fixedly connected to a test bench 5 through a fixed column, and a fixing mechanism is installed on the test bench 5, the fixing mechanism includes a vacuum cylinder 6 fixedly connected to the lower end of the test bench 5, the inner wall of the vacuum cylinder 6 is sealed and slidably connected to a sliding plug 7, the lower end of the sliding plug 7 is fixedly connected to a first rod 8, the lower end of the first rod 8 passes through the lower end of the vacuum cylinder 6 and is fixedly connected to a horizontal plate 9, an adsorption groove 10 is opened in the test bench 5, and a plurality of adsorption holes 11 are opened on the inner wall of the adsorption groove 10, and a one-way air outlet pipe 901 is fixedly connected to the side wall of the vacuum cylinder 6, and the vacuum cylinder 6 is connected to the adsorption groove through a one-way suction pipe 902 10 is connected. It should be noted that the one-way air outlet pipe 901 only allows the air in the vacuum cylinder 6 to be discharged, and the one-way air intake pipe 902 only allows the air in the adsorption tank 10 to enter the vacuum cylinder 6. The side wall of the pressure plate 4 is fixedly connected to the fixing frame 12, and the side wall of the first rod 8 is slidably connected to the lower end of the fixing frame 12. A correction mechanism is installed on the test bench 5. The correction structure includes a rotating shaft 13 rotatably connected to the upper end of the test bench 5, and the side wall of the rotating shaft 13 is fixedly connected to the correction plate 14. The upper end of the test bench 5 is fixedly connected to the mounting plate 16, and a first spring 15 is fixedly connected between the correction plate 14 and the mounting plate 16. A first groove 17 is opened in the mounting plate 16, and the inner wall of the first groove 17 is sealed and slidably connected to a magnetic slide 18. The side wall of the magnetic slide 18 is fixedly connected to a second rod 19, and one end of the second rod 19 passes through the side wall of the mounting plate 16 and is fixedly connected to an arc block 20.

[0029] It should be noted that a through hole is provided at the lower end of the vacuum cylinder 6 . When the sliding plug 7 slides in a sealed manner in the vacuum cylinder 6 , the through hole can balance the pressure changes in the vacuum cylinder 6 .

[0030] Furthermore, when the pressure plate 4 moves downward to test the load force of the foam board, the pressure plate 4 will drive the cross plate 9 to move downward through the fixing frame 12, and then drive the sliding plug 7 to slide downward and seal on the inner wall of the vacuum cylinder 6 through the first rod 8, and the air in the adsorption tank 10 will be sucked into the vacuum cylinder 6 through the one-way suction pipe 902, and the adsorption tank 10 will be pumped with negative pressure, and then the foam board can be firmly adsorbed and fixed by the adsorption hole 11, and the foam board is limited and fixed, so that it is not easy to move during the test.

[0031] The correction mechanism further includes a second groove 21 formed in the base 1. An annular groove 22 is formed at the top inside the second groove 21. The cross-section of the annular groove 22 is T-shaped. Two limiting rods 23 are symmetrically and slidably connected to the inner wall of the annular groove 22. The limiting rods 23 are T-shaped. A mounting block 24 is fixedly connected to the upper ends of the two limiting rods 23 together. A conducting rod 25 is fixedly connected to the side wall of the mounting block 24. A U-shaped magnet 26 is fixedly connected to the inner wall of the second groove 21. An electromagnet 27 is fixedly connected to the inner wall of the first groove 17. The electromagnet 27 is electrically connected to the conducting rod 25. A plurality of second springs 28 are fixedly connected to the inner wall of the first groove 17 and the side wall of the magnetic sliding plate 18 together. A lead screw 29 is fixedly connected to the lower end of the cross plate 9. The lower end of the lead screw 29 penetrates through the base 1. The side wall of the lead screw 29 is threadedly connected to the mounting block 24. A limiting plate 30 is fixedly connected to the upper end of the test bench 5.

[0032] It should be noted that when the lead screw 29 moves up and down, under the action of the annular groove 22 and the limiting rods 23, the mounting block 24 will rotate and will not move up and down together with the lead screw 29.

[0033] Further, when the hydraulic cylinder 3 drives the pressing plate 4 to move upward and reset, the lead screw 29 will also move upward, driving the mounting block 24 to rotate, driving the conducting rod 25 to rotate and intermittently cut the magnetic induction lines, so that an induced current is intermittently generated on the conducting rod 25. Furthermore, the electromagnet 27 will be intermittently powered on to generate magnetism. Under the action of the electromagnet 27 and the second springs 28, the magnetic sliding plate 18 will drive the arc-shaped block 20 to reciprocally press the correction plate 14, causing the correction plate 14 to swing back and forth to push the foam board, so that the side wall of the foam board fits against the limiting plate 30, preventing the foam board from tilting when the pushing plate 35 pushes the foam board for feeding, resulting in the foam board tilting when moving to the test position, and further causing the pressure of the pressing plate 4 on the foam board to be uneven, making the load force detection effect inaccurate.

[0034] A third spring 31 is sleeved on the side wall of the first rod 8. The lower end of the third spring 31 is fixedly connected to the cross plate 9, and the upper end of the third spring 31 is fixedly connected to the fixing frame 12. It should be noted that the spring constant of the third spring 31 is relatively large. When the pressing plate 4 moves downward and the sliding plug 7 slides downward, as long as the sliding plug 7 can still slide inside the air extraction cylinder 6, the third spring 31 will not be compressed. When the adsorption groove 10 is completely evacuated to a negative pressure and the sliding plug 7 cannot continue to slide downward, the fixing frame 12 will start to compress the third spring 31, enabling the pressing plate 4 to continue to move downward for a certain distance, providing sufficient pressure to perform a load force test on the foam board. When the pressing plate 4 moves upward and resets, the fixing frame 12 pulls the cross plate 9 and the lead screw 29 upward through the third spring 31. At this time, the force received by the third spring 31 is not enough to stretch it either.

[0035] An automatic feeding mechanism is installed on the mounting frame 2, and the automatic feeding mechanism includes a feeding box 32 fixedly connected to the side wall of the mounting frame 2, a third groove 33 is provided at the lower end of the feeding box 32, and a slide 34 is sealingly and slidingly connected to the inner wall of the third groove 33, a push plate 35 is fixedly connected to the side wall of the slide 34, and the push plate 35 is U-shaped, and the push plate 35 is slidingly connected to the side wall of the feeding box 32, an air bag 36 is fixedly connected to the top of the mounting frame 2, the air bag 36 is filled with hydraulic oil, the lower end of the air bag 36 is fixedly connected to the upper end of the pressure plate 4, the air bag 36 is communicated with the third groove 33 through the oil inlet pipe 37, and a discharge port 38 is provided on the side wall of the feeding box 32.

[0036] Furthermore, the hydraulic cylinder 3 is driven to shorten, causing the pressure plate 4 to reset. The pressure plate 4 will squeeze the airbag 36, and the hydraulic oil in the airbag 36 will be squeezed into the third groove 33. At this time, the slide plate 34 will slide to the left, driving the push plate 35 to move to the left, pushing the foam board in the loading box 32 onto the test bench 5, so that the foam board can be automatically loaded each time the test is completed, without the need for manual loading, and the load force test of the foam board can be carried out continuously and quickly, which makes the test more efficient and convenient.

[0037] A dust suction mechanism is installed on the mounting frame 2, and the dust suction mechanism includes two dust suction heads 39 symmetrically fixedly connected to the top of the mounting frame 2 through a fixed axis. The two dust suction heads 39 are respectively connected to the first groove 17 through two one-way dust suction pipes 40. Two one-way dust exhaust pipes 41 are fixedly connected to the inner wall of the first groove 17, and the other end of the one-way dust exhaust pipe 41 is connected to the external collection box. It should be noted that the one-way dust suction pipe 40 only allows the foam particles in the dust suction head 39 to enter the first groove 17, and the one-way dust exhaust pipe 41 only allows the foam particles in the first groove 17 to be discharged into the external collection box.

[0038] Furthermore, when the pressing plate 4 squeezes the foam board, the foam board may break and produce foam particles. When the pressing plate 4 moves upward to reset, the magnetic slide 18 will slide back and forth in a sealed manner in the first groove 17, generating a suction force, and the foam particles are drawn into the first groove 17 through the dust collection head 39 and the one-way dust collection tube 40 to remove the foam particles and prevent them from flying to other places or onto workers, causing cleaning troubles.

[0039] An air intake pipe 42 is fixedly connected to the inner wall of the adsorption tank 10, and a solenoid valve 43 is installed on the inner wall of the air intake pipe 42. The solenoid valve 43 is electrically connected to the conductive rod 25, and a diode is connected in series between the solenoid valve 43 and the conductive rod 25. It should be noted that the diode allows forward current to pass through, but blocks reverse current. This is a prior art. When the pressure plate 4 moves upward to reset, the screw 29 moves upward to drive the mounting block 24 to rotate, and drives the conductive rod 25 to rotate and cut the magnetic lines of force, so that the conductive rod 25 generates an induced current. At this time, the induced current can be passed into the solenoid valve 43 through the diode, so that the solenoid valve 43 is energized and opened, and the outside air will enter the adsorption tank 10 through the air intake pipe 42, thereby releasing the negative pressure in the adsorption tank 10 and thereby releasing the fixation of the foam board.

[0040] The push plate 35 is pushed to the left and the push plate 35 is pushed to the right, and the push plate 35 is pushed to the left and the push plate 35 is pushed to the right, and the push plate 35 is pushed to the left and the push plate 35 is pushed to the right, and the push plate 35 is pushed to the right and the push plate 35 is pushed to the right, and the push plate 35 is pushed to the right and the push plate 35 is pushed to the right, and the push plate 35 is pushed to the right and the push plate 35 is pushed to the right, and the push plate 35 is pushed to the right and the push plate 35 is pushed to the right, and the push plate 35 is pushed to the right and the push plate 35 is pushed to the right, and the push plate 35 is pushed to the right and the push plate

[0041] When the hydraulic cylinder 3 is shortened and drives the pressure plate 4 to move upward to reset, the push plate 35 will push the foam board to feed, and the pressure plate 4 will drive the cross plate 9 to move upward through the fixing frame 12, drive the screw 29 to move upward, and then drive the mounting block 24 to rotate, drive the conductive rod 25 to rotate, cut the magnetic flux lines, and generate intermittent current on the conductive rod 25, so that the intermittent current is passed through the electromagnet 27, and the electromagnet 27 will intermittently have magnetism. Under the action of the electromagnet 27 and the second spring 28, the magnetic slide 18 will move toward the inner wall of the first slot 17. The second rod 19 drives the arc block 20 to intermittently squeeze the correction plate 14. The correction plate 14 will continue to swing under the action of the arc block 20 and the first spring 15, so that the side wall of the correction plate 14 continuously pushes the foam plate, so that the side wall of the foam plate fits with the limit plate 30, thereby preventing the foam plate from being skewed when the push plate 35 pushes the foam plate to feed, causing the foam plate to be skewed when moving on the test bench 5, resulting in the foam plate being skewed when moving to the test position, and then the pressure of the pressure plate 4 on the foam plate is uneven, making the load force detection effect inaccurate.

[0042] When the foam plate moves to the test position just below the pressure plate 4, the hydraulic cylinder 3 is driven to extend and drive the pressure plate 4 to move downward. At this time, the pressure plate 4 will move downward through the fixing frame 12. Since the third spring 31 has a large spring coefficient, the fixing frame 12 will drive the cross plate 9 to move downward through the third spring 31, and the third spring 31 will not be compressed. The cross plate 9 will drive the first rod 8 to move downward, driving the sliding plug 7 to slide downward and seal. Under the action of the sliding plug 7, the air in the adsorption groove 10 will be sucked into the suction cylinder 6 through the one-way suction pipe 902 until the adsorption groove 10 is completely pumped into the negative pressure. At this time, the foam plate will be fixed in the test position under the action of the multiple adsorption holes 11. When the adsorption groove 10 is completely pumped into the negative pressure, the sliding plug 7 cannot continue to slide downward in the suction cylinder 6. At this time, the pressure plate 4 continues to move downward to apply pressure, and the fixing frame 12 will begin to compress the third spring 31, so that the pressure plate 4 can continue to move downward one end distance, providing sufficient pressure to perform load force detection on the foam plate.

[0043] As the horizontal plate 9 moves downward, the lead screw 29 also moves downward, driving the mounting block 24 to rotate, driving the conductive rod 25 to rotate, cutting the magnetic lines of force, and generating an induced current on the conductive rod 25. Since a diode is connected in series between the solenoid valve 43 and the conductive rod 25, under the action of the diode, the solenoid valve 43 cannot be powered on and opened at this time.

[0044] When the load force test is over, the hydraulic cylinder 3 contracts and drives the pressure plate 4 to move upward and reset. The pressure plate 4 drives the cross plate 9 upward through the fixing frame 12, drives the first rod 8 upward, and then drives the sliding plug 7 to slide upward and reset. The air in the vacuum cylinder 6 will be discharged through the one-way air outlet pipe 901. At this time, the screw 29 moves upward and drives the mounting block 24 to reverse, drives the conductive rod 25 to reverse, so that a reverse current is generated on the conductive rod 25. At this time, the solenoid valve 43 will be energized and opened, and the outside air will enter the adsorption tank 10, so that the negative pressure in the adsorption tank 10 is released, and the fixation of the foam board is released.

[0045] At this time, the electromagnet 27 will also be energized to drive the magnetic slide 18 to slide back and forth in a sealed manner on the inner wall of the first groove 17. Under the action of the magnetic slide 18, the foam particles generated by the foam board being crushed will be sucked into the first groove 17 through the two dust suction heads 39 and the one-way dust suction pipe 40. Then the foam particles will be squeezed into the external collection box through the one-way dust exhaust pipe 41, thereby removing the foam particles generated by the foam board during the load force detection process, preventing them from flying to other places and workers, causing cleaning troubles.
