Description

Technical Field

[0001] The present invention relates to the technical field of thermal insulation flake detection, in particular to a porosity detection device for thermal insulation flakes. Background Art

[0002] Thermal insulation flakes refer to flakes of flocculent sediment. They can also refer to sheet-like cotton materials made from plant, animal, or chemical fibers for warmth, insulation, or shock absorption. During the thermal insulation flake processing process, the porosity of the flakes must be tested to determine their thermal performance.

[0003] When testing the porosity of thermal insulation sheets, it is necessary to ensure the cleanliness of the sheets. Therefore, the sheets must be cleaned and then dried to ensure that they are both clean and dry before testing, thereby ensuring the accuracy of the test. However, during the drying process, a large amount of moisture will accumulate inside the sheets, slowing the drying process.

[0015] The present invention has the following beneficial effects:

[0016] 1. The thermal insulation flake porosity detection device allows the thermal insulation flakes to enter the heating box along the conveyor line for heating and drying before the thermal insulation flakes are tested. During drying, the extrusion plate moves downward, so that the extrusion plate cooperates with the placement plate to press the thermal insulation flakes, which is convenient for discharging moisture inside the thermal insulation flakes, and is beneficial to improving drying efficiency. At the same time, when the extrusion plate squeezes the thermal insulation flakes, the placement plate is driven to rotate by the rotation shaft, and the placement plate drives the thermal insulation flakes to rotate. The centrifugal effect is used to more conveniently discharge the squeezed moisture, reduce the amount of residual moisture on the surface of the placement plate, and reduce the possibility of moisture being absorbed back into the thermal insulation flakes, which is beneficial to improving the drainage effect and further improving the drying efficiency.

[0017] 2. The thermal insulation sheet porosity detection device, when the rotating shaft drives the placement plate to rotate, slides along the second slide groove through the core rod, drives the third limit ball to slide along the first track groove, so that the third limit ball can drive the core rod to reciprocate up and down, and the up and down reciprocating motion of the core rod drives the push plate to reciprocate up and down in the accommodating groove, and the push plate drives the sleeve rod to reciprocate left and right through the adjusting component, so that the placement plate can swing back and forth left and right while rotating in a circle, thereby making it more convenient to drain water from the surface of the placement plate, achieving a better drying effect and further improving the drying efficiency.

[0018] 3. The porosity detection device for the thermal insulation flakes is moved out from the upper surface of the placement plate through the first landing gear after the moisture in the thermal insulation flakes is squeezed out, so that the first landing gear lifts the thermal insulation flakes, so that the lower surface of the thermal insulation flakes is in an overhead state, thereby increasing the air circulation on the lower surface of the thermal insulation flakes, which is conducive to the rapid drying of the lower surface of the thermal insulation flakes and the better drying effect. At the same time, by alternately raising and lowering the first landing gear and the second landing gear, and the different contact positions of the first landing gear and the second landing gear with the thermal insulation flakes, the support position of the thermal insulation flakes can be changed, thereby preventing the contact position of the thermal insulation flakes from being blocked all the time, resulting in the problem of slow drying efficiency at the contact position, and further improving the drying efficiency.

DETAILED DESCRIPTION

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] For example 1, please refer to Figures 1-15A device for detecting the porosity of thermal insulation flakes comprises a conveyor line 2 arranged on a fixed base 1, a heating box 3 and a detection station 5 for detecting thermal insulation flakes 4 are arranged on the outside of the conveyor line 2, a bottom plate 6 is fixed on the conveyor line 2, a rotating shaft 7 is rotatably arranged on the bottom plate 6, a placement plate 8 for placing the thermal insulation flakes 4 is arranged above the rotating shaft 7, and an extrusion plate 9 is arranged above the placement plate 8. The extrusion plate 9 squeezes and drains the thermal insulation flakes 4 by moving downward; A first chute 10 is defined within the fixed base 1 for the rotation shaft 7 to slide in. A first limiting ball 11 is fixed to the bottom end of the rotation shaft 7. A spherical groove 12 is defined at the bottom end of the first chute 10 for the first limiting ball 11 to slide in. A first gear 13 is fixed on the circumference of the rotation shaft 7. A toothed plate 14 for meshing with the first gear 13 is fixed to the inner wall of the first chute 10. A support frame 15 is fixed to the upper surface of the base plate 6, a servo motor 16 is fixed to the top of the support frame 15, a reciprocating screw 17 is fixed to the output end of the servo motor 16, a moving rod 18 is threadedly connected to the circumference of the reciprocating screw 17, a servo electric cylinder 19 is fixed to the end of the moving rod 18, a connecting column 20 is fixed to the output end of the servo electric cylinder 19, a second limiting ball 21 is fixed to the bottom of the connecting column 20, and a spherical rotating groove 22 for the second limiting ball 21 to rotate is opened inside the extrusion plate 9.

[0037] In this technical solution, before testing, impurities may exist on the surface or inside of the thermal insulation wadding 4. In order to prevent the impurities from affecting the porosity test of the thermal insulation wadding 4, the thermal insulation wadding 4 needs to be cleaned to remove the impurities. After the thermal insulation wadding 4 is cleaned, liquid water adheres to the fiber surface or fills the pores, which will be included in the material volume during the porosity test, resulting in an overestimate of the measured apparent volume and a lower porosity calculation result. Therefore, the thermal insulation wadding 4 needs to be dried. During the inspection, the thermal insulation sheet 4 is placed on the placement plate 8, and the bottom plate 6 is driven to move synchronously by the conveyor line 2. The bottom plate 6 drives the rotating shaft 7 to slide along the first slide groove 10, and the rotating shaft 7 drives the first limit ball 11 to slide along the spherical groove 12 until the thermal insulation sheet 4 is sent into the heating box 3. At this time, the servo electric cylinder 19 pushes the connecting column 20 to move downward, and the connecting column 20 drives the extrusion plate 9 to move downward, so that the extrusion plate 9 squeezes the thermal insulation sheet 4 to squeeze out the water inside the thermal insulation sheet 4, and then the extrusion plate 9 is reset, and the thermal insulation sheet 4 is dried by the heating box 3. By squeezing out the water inside the thermal insulation sheet 4, the drying efficiency of the thermal insulation sheet 4 can be increased. When the heating box 3 is heated, the drying is completed, and the servo motor 16 drives the reciprocating screw 17 to rotate, the reciprocating screw 17 drives the moving rod 18 to move, and the moving rod 18 drives the extrusion plate 9 to move, and the extrusion plate 9 is removed from above the placement plate 8, and then reaches the detection station 5, and the porosity of the thermal insulation sheet 4 is detected by the detection station 5; in this application, the heating box 3 is used to heat and dry the thermal insulation sheet 4, and the detection station 5 can use a laser frequency comb 3D profilometer to scan the thermal insulation sheet 4 with a laser to detect the internal fiber structure of the thermal insulation sheet 4, thereby detecting the porosity, and the heating box 3 and the detection station 5 are both existing technologies, not the innovation point in this application, and are not described in detail; If the placement plate 8 is designed to be the same size as the thermal insulation flakes 4, when squeezing the thermal insulation flakes 4, the edges of the thermal insulation flakes 4 are squeezed and deformed, and will protrude outward, causing some water to accumulate there, and the water cannot be fully squeezed out. In order to fully squeeze out the water in the thermal insulation flakes 4, the placement plate 8 and the squeezing plate 9 are first designed to be larger than the thermal insulation flakes 4. Therefore, when the squeezing plate 9 and the placement plate 8 cooperate to squeeze out the water inside the thermal insulation flakes 4, some of the squeezed water will remain at the edge of the placement plate 8. When the squeezing plate 9 is reset, a small amount of water will be squeezed out. The water will be sucked into the warming flakes 4 again, thereby reducing the drying efficiency. To address this problem, after the squeezing plate 9 squeezes the warming flakes 4, the first gear 13 engages with the tooth plate 14. When the rotating shaft 7 slides along the first chute 10, the first gear 13 drives the rotating shaft 7 to rotate, and the rotating shaft 7 drives the placement plate 8 to rotate. The placement plate 8 drives the warming flakes 4 and the squeezing plate 9 to rotate synchronously. The centrifugal force generated during the rotation is used to throw out the water remaining on the surface of the placement plate 8, thereby increasing the water discharge effect and further improving the drying efficiency. In order to increase the stability of the placement plate 8 and the extrusion plate 9 when sliding, an electric push rod 54 is fixed on the surface of the support frame 15, and a limiting longitudinal plate 55 is fixed on the output end of the electric push rod 54. The initial state of the limiting longitudinal plate 55 is as follows: Figure 5As shown, the positioning plate 55 contacts one side of the placement plate 8 and the extrusion plate 9, so that before the first gear 13 meshes with the tooth plate 14, the placement plate 8 and the extrusion plate 9 will not deflect. Before the first gear 13 meshes with the tooth plate 14, the electric push rod 54 contracts to move the limiting longitudinal plate 55 away from one side of the placement plate 8, thereby not affecting the rotation of the placement plate 8. After the rotation is completed, the limiting longitudinal plate 55 can be reset and contact the placement plate 8 and the extrusion plate 9 again. In order to further improve the stability of the extrusion plate 9, a circular ring 56 is provided on the surface of the connecting column 20 for rotation. Several groups of springs 57 are fixed between the lower surface of the circular ring 56 and the extrusion plate 9. Several groups of springs 57 are arranged in a circular array on the circular ring 56, so that the extrusion plate 9 can remain horizontal in the absence of external force and will not affect the subsequent rotation of the extrusion plate 9.

[0038] In the second embodiment, when the placement plate 8 rotates, the centrifugal effect is used to throw away the water remaining on the surface of the placement plate 8. Since the placement plate 8 is placed horizontally, the throwing effect is poor. To solve this problem, this embodiment is an improvement made on the basis of the first embodiment. For details, please refer to Figures 1-15 , a core rod 23 is provided for sliding inside the rotating shaft 7, a second slide groove 24 for the core rod 23 to slide is provided at the bottom of the spherical groove 12, a rotating rod 25 is provided on the top of the rotating shaft 7, a sleeve rod 26 is fixed on the circumference of the rotating rod 25, the top of the sleeve rod 26 is fixed to the extrusion plate 9, a push plate 27 is fixed to the top of the core rod 23, and an accommodating groove 28 for the push plate 27 to slide is provided inside the rotating shaft 7, and an adjusting component for driving the extrusion plate 9 to shake is provided inside the rotating shaft 7; A third limiting ball 29 is fixed to the bottom end of the core rod 23. A first track groove 30 for sliding the third limiting ball 29 is formed at the bottom of the second slide groove 24. The first track groove 30 includes a first horizontal portion 301 and a first wavy portion 302 that are connected to each other. The adjustment assembly includes a rack 31 fixed to the push plate 27 , and a second gear 32 meshing with the rack 31 is fixed to the end of the rotating rod 25 , and the second gear 32 is rotatably disposed in the rotating shaft 7 .

[0039] In this technical solution, after the first gear 13 is engaged with the tooth plate 14, when driving the rotating shaft 7 to rotate, the third limiting ball 29 slides from the first horizontal portion 301 of the first track groove 30 to the first wave portion 302. When the third limiting ball 29 slides along the first wave portion 302, it drives the core rod 23 to reciprocate up and down. The core rod 23 drives the push plate 27 to reciprocate up and down inside the accommodating groove 28. The push plate 27 drives the rack 31 to reciprocate up and down. The rack 31 drives the second gear 32 to rotate forward and reverse, so that the rotating rod 25 drives the sleeve rod 26 to swing left and right, and the sleeve rod 26 drives the placement plate 8 to swing left and right, so that the placement plate 8 swings left and right while rotating, so that the water on the surface of the placement plate 8 can be better thrown out, further improving the drying effect.

[0040] Example 3: This example is another technical solution for adjusting the assembly. For details, please refer to Figures 1-15 The adjustment assembly includes a convex plate 33 fixed to the push plate 27, a sliding rod 34 is slidably provided on the convex plate 33, a sliding protrusion 35 is fixed to one end of the sliding rod 34, and an inclined groove 36 for the sliding protrusion 35 to slide is provided on the inner wall of the accommodating groove 28. An adjusting rod 37 is fixed to the bottom of the sleeve rod 26, and the adjusting rod 37 is slidably set in the rotating shaft 7. A fourth limiting ball 38 is fixed to the other end of the sliding rod 34, and a limiting groove 39 for the fourth limiting ball 38 to slide is provided on the adjusting rod 37.

[0041] In the present technical solution, when the push plate 27 reciprocates up and down in the accommodating groove 28, it drives the convex plate 33 to reciprocate up and down. The reciprocating up and down motion of the convex plate 33 drives the sliding rod 34 to reciprocate up and down. The sliding rod 34 drives the sliding protrusion 35 to slide up and down along the inclined groove 36. The sliding protrusion 35 slides up and down along the inclined groove 36 to make the sliding rod 34 reciprocate left and right. The reciprocating left and right motion of the sliding rod 34 pushes the adjusting rod 37 to reciprocate left and right. The adjusting rod 37 drives the sleeve rod 26 to swing back and forth left and right, so that the placement plate 8 swings left and right while rotating, so that the water on the surface of the placement plate 8 can be better thrown out, further improving the drying effect. In this technical solution, the slide rod 34 can only move left and right relative to the protruding plate 33, so that the slide rod 34 can extend from the inside of the protruding plate 33 or retract into the inside of the protruding plate 33. When the slide rod 34 moves up and down and left and right, the slide rod 34 drives the fourth limiting ball 38 to slide inside the limiting groove 39, so that the slide rod 34 can drive the adjusting rod 37 to move back and forth left and right without getting stuck.

[0042] In the fourth embodiment, after the water inside the thermal insulation floss 4 is squeezed out, the bottom plate 6 of the thermal insulation floss 4 contacts the surface of the placement plate 8, which makes the ventilation effect at the bottom of the thermal insulation floss 4 poor. Therefore, the drying effect at the bottom of the thermal insulation floss 4 is poor, thereby reducing the drying efficiency. To address this problem, this embodiment is an improvement made on the basis of the second or third embodiment. For details, please refer to Figures 1-15 The upper surface of the placement plate 8 is fitted with a first landing gear 40, a connecting plate 41 is fixed to the bottom of the first landing gear 40, a first push rod 42 is penetrated by the bottom plate 6, a third sliding groove 43 for the first push rod 42 to slide is provided on the fixed base 1, and a first plug post 44 for inserting the first push rod 42 is fixed to the bottom of the connecting plate 41; A fifth limiting ball 45 is fixed to the bottom end of the first push rod 42 . A second track groove 46 for sliding the fifth limiting ball 45 is defined at the bottom end of the third sliding groove 43 . The second track groove 46 includes a second horizontal portion 461 and a second wavy portion 462 that are connected to each other.

[0043] In this technical solution, after the placement plate 8 rotates, the placement plate 8 and the extrusion plate 9 are both reset to their initial positions. Figure 3 The bottom plate 6 then continues to move with the conveyor line 2, and the bottom plate 6 drives the first push rod 42 to slide along the third slide groove 43, and the first push rod 42 drives the fifth limiting ball 45 to slide along the second track groove 46. When the fifth limiting ball 45 slides from the second horizontal portion 461 to the second wave portion 462, the second wave portion 462 includes a first rising portion 4621, a fourth horizontal portion 4622 and a first descending portion 4623. First, the fifth limiting ball 45 slides along the first rising portion 4621, so that the fifth limiting ball 45 drives the first push rod 42 to move upward, so that the first push rod 42 first moves upward and is inserted into the first plug column 44, and then drives the first plug column 44 to move The first locking post 44 moves upward, driving the connecting plate 41 to move upward. The connecting plate 41 drives the first landing gear 40 to move upward, pushing the first landing gear 40 out from the upper surface of the placement plate 8. Then, the fifth limiting ball 45 slides along the fourth horizontal portion 4622, causing the first landing gear 40 to lift the thermal insulation sheet 4 for a period of time. The first landing gear 40 is used to lift the lower surface of the thermal insulation sheet 4, thereby exposing the lower surface of the thermal insulation sheet 4 to the outside, increasing air circulation and improving the drying efficiency of the thermal insulation sheet 4. The fifth limiting ball 45 then slides along the first descending portion 4623, causing the first landing gear 40 to return to its original position. In this technical solution, if Figure 3As shown, the first push rod 42 does not contact the placement plate 8 at the beginning, so that the placement plate 8 will not touch the first push rod 42 when swinging, and there is no mutual influence between the two. In the process of swinging of the placement plate 8, the first push rod 42 drives the fifth limiting ball 45 to slide on the second horizontal part 461, so that the first push rod 42 and the bottom plate 6 always remain stationary.

[0044] In the fifth embodiment, when the first landing gear 40 lifts the thermal insulation sheet 4, the ventilation effect at the contact position between the first landing gear 40 and the thermal insulation sheet 4 is poor, thereby affecting the drying efficiency at the contact position and creating a drying dead corner. To address this issue, this embodiment is an improvement made on the basis of the fourth embodiment. For details, please refer to Figures 1-15 A second landing gear 47 is embedded on the upper surface of the placement plate 8, a connecting block 48 is fixed to the bottom of the second landing gear 47, a second push rod 49 is penetrated on the bottom plate 6, a fourth sliding groove 50 for the second push rod 49 to slide is opened on the fixed base 1, and a second plug 51 for inserting the second push rod 49 is fixed to the bottom of the connecting block 48; A sixth limiting ball 52 is fixed to the bottom end of the second push rod 49 , and a third track groove 53 for sliding the sixth limiting ball 52 is defined at the bottom end of the fourth slide groove 50 . The third track groove 53 includes a third horizontal portion 531 and a third wavy portion 532 that are connected to each other.

[0045] In this technical solution, when the base plate 6 continues to move with the conveyor line 2, the base plate 6 will also drive the second push rod 49 to slide along the fourth slide groove 50, and the second push rod 49 will drive the sixth limiting ball 52 to slide along the third track groove 53. The third track groove 53 includes a second rising portion 5321, a fifth horizontal portion 5322 and a second descending portion 5323. When the fifth limiting ball 45 slides along the first descending portion 4623, the sixth limiting ball 52 slides along the second rising portion 5321, so that the sixth limiting ball 52 drives the second push rod 49 to move upward, so that the second push rod 49 first moves upward and is inserted into the second plug column 51, and then drives the second plug column 51 to move upward. The upward movement of the second plug column 51 drives the connecting block 48 to move upward, and the connecting block 48 drives the second lifting rod 49 to move upward. The landing gear 47 moves upward, pushing the second landing gear 47 from the upper surface of the placement plate 8, and supporting the bottom of the thermal insulation sheet 4 with the second landing gear 47. At this time, the first landing gear 40 continues to move downward to reset, and the second landing gear 47 continues to move upward to lift the thermal insulation sheet 4 to the highest position. Then, the sixth limiting ball 52 slides along the fifth horizontal portion 5322, so that the second landing gear 47 lifts the thermal insulation sheet 4 for a period of time, and the second landing gear 47 is used to suspend the lower surface of the thermal insulation sheet 4, which can change the supporting position of the lower surface of the thermal insulation sheet 4. The first landing gear 40 and the second landing gear 47 are used to alternately support the bottom of the thermal insulation sheet 4, thereby increasing the drying effect of the thermal insulation sheet 4, reducing the drying dead angle, and further improving the drying efficiency. In this technical solution, the second push rod 49 is in the same state as the first push rod 42. The second push rod 49 does not contact the placement plate 8 at the beginning, so that when the placement plate 8 swings, it will not touch the second push rod 49. There is no mutual influence between the two. In addition, during the swinging process of the placement plate 8, the second push rod 49 drives the sixth limiting ball 52 to slide on the third horizontal portion 531, so that the second push rod 49 and the bottom plate 6 always remain in a stationary state. In this technical solution, when the first landing gear 40 descends, the second landing gear 47 rises, and when the second landing gear 47 descends, the first landing gear 40 rises, so that the thermal insulation sheet 4 will not fall onto the placement plate 8 when changing the support position, thereby further improving the drying effect; in addition, the second wave portion 462 and the third wave portion 532 are both arranged within the range of the bottom plate 6 sliding along the inside of the heating box 3.
