Description

TECHNICAL FIELD

[0001] The present application relates to hot press forming equipment technical field, more particularly, the present application relates to a kind of hot press forming equipment of aerogel composite felt. BACKGROUND

[0002] Aerogel composite material is a new type of lightweight material with nanoscale pore structure and high specific surface area, which combines the excellent thermal insulation performance of aerogel and the mechanical strength of composite material, so it has wide application prospect in many fields. The hot press forming machine is suitable for mixing and processing of rubber, plastic industry polymers such as PVC, color master batch, felt and other chemical raw materials, and for material testing. The plastic or rubber raw material is placed in the mold and clamped between the upper and lower electric heating plates. Under the intelligent constant temperature of the electric heating plate, pressure is applied to make the raw material form.

[0003] However, the traditional hot press forming equipment for aerogel composite felt lacks a structure that can provide flexible assistance during the hot press forming process of aerogel composite felt. That is, the existing technology lacks a structure that can repeatedly and quickly extrude aerogel composite felt during hot pressing to improve the hot pressing effect of aerogel composite felt. This leads to the passive hot pressing of existing aerogel composite felt, which affects the hot pressing effect and the tightness of the composite process in some positions. At the same time, the existing technology lacks a structure that can accurately control the pressing degree of aerogel composite felt of different thicknesses. That is, it is impossible to control the extrusion force and height of aerogel composite felt of different thicknesses, making it difficult to control the pressure effect of aerogel composite felt of different thicknesses.

[0004] In view of the above technical defects, a solution is provided. SUMMARY

[0008] In a preferred embodiment, the top of the push box is provided with a slot, and the top of the push box is provided with a plurality of first top plate strips. The plurality of first top plate strips are arranged at equal intervals and are arranged horizontally.

[0009] In a preferred embodiment, a first push plate is fixedly installed at the bottom of a plurality of first top plate strips, and a second push plate is fixedly installed at the bottom of a plurality of second top plate strips. The first push plate and the second push plate are slidably installed on the inner wall of the processing table, and the first push plate and the second push plate are staggered from each other.

[0010] In a preferred embodiment, the bottom of the first push plate and the second push plate are respectively fixedly installed with belt blocks. The inner walls of the two belt blocks are provided with elliptical grooves. The inner walls of the elliptical grooves are provided with push rods. The two push rods are staggered. A rotating column is fixedly installed on one side of the two push rods. The rotating column is horizontally positioned. Fixing plates are rotatably installed on the outer walls of both sides of the rotating column. The fixing plates are fixedly installed on the inner wall of the processing table. A first gear is fixedly installed on the inner wall of the rotating column. The first gear is vertically positioned. A second gear meshes with one side of the first gear. A rotary motor is provided on one side of the second gear. The rotary motor is fixedly installed on the inner wall of the processing table. The output end of the rotary motor is fixedly connected to the outer wall of the second gear.

[0011] In a preferred embodiment, the roller control mechanism includes inclined grooves formed on both sides of the bottom of the push box. The outer wall of the inclined grooves is provided with padding strips. The two padding strips are arranged horizontally and the tops of the two padding strips are arranged at an angle. The tops of the two padding strips are in contact with the inclined grooves on both sides of the bottom of the push box. The two padding strips are arranged symmetrically. A rotating crossbar is provided on each side of the two padding strips. The outer wall of the two rotating crossbars is provided with threaded grooves. The rotating crossbars are threadedly connected to the two padding strips.

[0012] In a preferred embodiment, one end of each of the two rotating crossbars is fixedly mounted with a rotating gear. The two rotating gears are arranged symmetrically to each other.

[0014] The technical effects and advantages of this invention are as follows: This invention employs a roller control mechanism. The thickness of the aerogel composite felt itself lifts and rotates a friction roller. This friction roller then drives the auger rollers on both sides to push the aerogel composite felt to both sides, making it flat. The upward movement of the friction roller causes the two padding strips to move away from each other, allowing the push box to adjust its height according to the thickness of the aerogel composite felt. Simultaneously, an alternating pressing mechanism is located within the push box to synchronously adjust its height. Inside the push box, a rotary motor drives multiple first top plates and multiple second belt push plates at the top of the push box to alternately move upwards. This allows the multiple first and second belt push plates to quickly and alternately move upwards, supporting the bottom inner wall of the extrusion conveyor belt. This enables repeated and rapid extrusion of the aerogel composite felt during hot pressing, improving the hot pressing effect and preventing insufficient pressure in some areas from affecting the hot pressing effect and the tightness of the composite process.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1

[0024] Traditional hot pressing equipment for aerogel composite felts lacks a structure that can flexibly assist in applying pressure during the hot pressing process. In other words, existing technology lacks a structure that can repeatedly and rapidly compress the aerogel composite felt during hot pressing to improve the hot pressing effect. Consequently, existing hot pressing equipment for aerogel composite felts can only passively apply pressure, resulting in insufficient pressure in some areas and affecting the hot pressing effect and the tightness of the composite process. To solve this problem, the following technical solution is proposed: Refer to the instruction manual appendixFigures 1-7 A hot pressing molding device for aerogel composite felt, such as Figure 1 and Figure 2 As shown, the equipment includes a processing table 1, conveyor rollers 2 on both sides of the processing table 1, a conveyor belt 3 rotatably mounted on the outer wall of the two conveyor rollers 2, a hot press body 4 on the top of the conveyor belt 3, an alternating pressing mechanism 5 inside the conveyor belt 3, the alternating pressing mechanism 5 can reciprocate to lift the top surface of the conveyor belt 3 on one side inside the conveyor belt 3 to apply pressure to the aerogel composite felt on the conveyor belt 3, and a roller control mechanism 6 on the top of the conveyor belt 3 can synchronously lift the aerogel composite felt on the conveyor belt 3 to a corresponding height and apply a squeezing force from the middle to both sides to the top surface of the aerogel composite felt to facilitate flattening.

[0025] like Figure 2 and Figure 3 As shown, the alternating pressing mechanism 5 includes a push box 51 disposed in the middle of the conveyor belt 3. The push box 51 is slidably installed on the inner wall of the processing table 1. The push box 51 is arranged in a horizontal state, and the top of the push box 51 is in close contact with the inner wall of the conveyor belt 3. The push box 51 can fit against the bottom inner wall of the conveyor belt 3 to form a support.

[0026] like Figure 3 and Figure 4 As shown, the top of the push box 51 is provided with a slot, and the top of the push box 51 is provided with a plurality of first top plate strips 52. The plurality of first top plate strips 52 are arranged at equal intervals and are arranged horizontally. A plurality of second top plate strips 53 are provided between the plurality of first top plate strips 52. The plurality of second top plate strips 53 and the plurality of first top plate strips 52 are arranged in a mutually complementary manner, and the plurality of second top plate strips 53 and the plurality of first top plate strips 52 are arranged vertically intersecting. Multiple first belt push plates 54 and second belt push plates 55 alternately move upward to support and squeeze the bottom inner wall of the conveyor belt 3.

[0027] like Figure 3 and Figure 4 As shown, a first push plate 54 is fixedly installed on the bottom of a plurality of first top plate strips 52, and a second push plate 55 is fixedly installed on the bottom of a plurality of second top plate strips 53. The first push plate 54 and the second push plate 55 are slidably installed on the inner wall of the processing table 1, and the first push plate 54 and the second push plate 55 are staggered from each other. The first push plate 54 and the second push plate 55 move upward alternately, driving multiple first top plate strips 52 and multiple second push plates 55 to move upward alternately.

[0028] like Figure 4 and Figure 5As shown, the bottom of the first push plate 54 and the second push plate 55 are respectively fixedly installed with the same belt block 56. The inner wall of the two same belt blocks 56 is provided with an elliptical groove. The inner wall of the elliptical groove is provided with a push rod 57. The two push rods 57 are staggered. A rotating column 58 is fixedly installed on one side of the two push rods 57. The rotating column 58 is set in a horizontal state. The outer walls on both sides of the rotating column 58 are rotatably installed with a fixing plate 59. The fixing plate 59 is fixedly installed on the inner wall of the processing table 1. A first gear 510 is fixedly installed on the inner wall of the rotating column 58. The first gear 510 is set in a vertical state. A second gear 511 meshes with one side of the first gear 510. A rotary motor 512 is provided on one side of the second gear 511. The rotary motor 512 is fixedly installed on the inner wall of the processing table 1. The output end of the rotary motor 512 is fixedly connected to the outer wall of the second gear 511. The rotary motor 512 drives the second gear 511 to rotate rapidly, which in turn drives the first gear 510 to rotate synchronously. That is, the first gear 510 drives the rotating column 58 to rotate rapidly. The rotating column 58 drives the push rods 57 on both sides to rotate synchronously. Since the push rods 57 on both sides are in an eccentric position and are staggered, the two push rods 57 rotate alternately in an up-down state. Thus, the two push rods 57 drive the compression and push the belt block 56 to move up and down alternately. The two belt blocks 56 drive the first belt push plate 54 and the second belt push plate 55 to move up and down alternately.

[0029] In practical implementation, the rotary motor 512 drives the second gear 511 to rotate rapidly, which in turn drives the first gear 510 to rotate synchronously. This means the first gear 510 drives the rotating column 58 to rotate rapidly, and the rotating column 58 drives the push rods 57 on both sides to rotate synchronously. Since the push rods 57 are eccentrically positioned and staggered, they rotate alternately up and down. This causes the two push rods 57 to compress and push the belt blocks 56 to move alternately up and down. The two belt blocks 56 then drive the first belt pusher plate 54 and the second belt... The pusher plate 55 moves up and down alternately. The first pusher plate 54 and the second pusher plate 55 move upward alternately, driving multiple first top plate strips 52 and multiple second pusher plates 55 to move upward alternately. The multiple first pusher plates 54 and the second pusher plates 55 can quickly move upward alternately to support and squeeze the bottom inner wall of the conveyor belt 3. This allows for repeated and rapid compression of the aerogel composite felt during hot pressing, thereby improving the hot pressing effect of the aerogel composite felt and avoiding insufficient hot pressing pressure in some areas, which would affect the hot pressing effect of the aerogel composite felt and the tightness of the composite process. Example 2

[0030] Existing technologies lack the ability to accurately control the processing degree of aerogel composite mats of different thicknesses. Specifically, they cannot control the corresponding extrusion force and height of aerogel composite mats of different thicknesses, making it difficult to achieve self-controlled pressure effects for aerogel composite mats of varying thicknesses. To address this problem, the following technical solution is proposed: like Figure 6 and Figure 7 As shown, the roller control mechanism 6 includes inclined grooves on both sides of the bottom of the push box 51. The outer wall of the inclined groove is provided with a pad plate 61. The two pad plates 61 are set in a horizontal state and the top of the two pad plates 61 is set in an inclined state. The top of the two pad plates 61 fits into the inclined grooves on both sides of the bottom of the push box 51. The two pad plates 61 are symmetrically arranged. The two sides of the two pad plates 61 are respectively provided with a rotating crossbar 62. The outer wall of the two rotating crossbars 62 is provided with a threaded groove. The rotating crossbars 62 are threadedly connected to the two pad plates 61. When the two horizontal bars 62 rotate, they drive the two pad plates 61 to move synchronously through the threaded grooves on their outer walls. The threaded grooves at corresponding positions of the two pad plates 61 are symmetrically arranged, meaning that the two pad plates 61 slide in a state of approaching or moving away from each other when subjected to force.

[0031] like Figure 6 and Figure 7 As shown, one end of each of the two rotating crossbars 62 is fixedly mounted with a rotating gear 63. The two rotating gears 63 are arranged symmetrically to each other. The outer walls of the two rotating gears 63 are respectively meshed with toothed plates 64. The two toothed plates 64 are slidably mounted on the outer wall of the processing table 1. The two toothed plates 64 are arranged in an inverted L shape. The outer walls of the two toothed plates 64 are fixedly mounted with support springs 65. The support springs 65 are fixedly mounted on the outer wall of the processing table 1. When the two toothed plates 64 move upward, they can stretch the support spring 65 and drive the rotating gear 63 to rotate through the teeth on its surface. The rotation of the rotating gear 63 drives the rotating crossbar 62 to rotate synchronously.

[0032] like Figure 7 As shown, a belt lifting rod 66 is fixedly installed at the bottom of two toothed plates 64. The belt lifting rod 66 is set in a horizontal state. A friction top roller 67 is rotatably installed on the outer wall of the middle part of the belt lifting rod 66. The friction top roller 67 is set in a horizontal state. The bottom outer wall of the friction top roller 67 is parallel to the top outer wall of the conveyor belt 3. A auger roller 68 is rotatably installed on the outer walls of both sides of the friction top roller 67. The two auger rollers 68 are symmetrically arranged. The bottom of the two auger rollers 68 is parallel to the top outer wall of the conveyor belt 3. The bottom of the two auger rollers 68 is flush with the bottom of the friction top roller 67. As the aerogel composite felt moves forward on the conveyor belt 3, the thickness of the aerogel composite felt itself lifts the friction roller 67, causing the friction roller 67 to move upward and roll. This causes the friction roller 67 to drive the belt lifting rod 66 to move upward synchronously, which in turn drives the belt toothed plate 64 to move upward. The rotation of the friction roller 67 also drives the auger rollers 68 on both sides to rotate synchronously. When the auger rollers 68 on both sides rotate, they push the aerogel composite felt to both sides through the auger structure on their surface. This pushes the surface of the aerogel composite felt from the middle to both sides, making it easier to flatten the aerogel composite felt.

[0033] In specific implementation, when the aerogel composite felt on the conveyor belt 3 moves forward, the thickness of the aerogel composite felt itself lifts the friction roller 67, so the friction roller 67 is forced to move upward and roll. That is, the friction roller 67 drives the belt lifting rod 66 to move upward synchronously, the belt lifting rod 66 drives the belt tooth plate 64 to move upward, and the rotation of the friction roller 67 drives the auger rollers 68 on both sides to rotate synchronously. When the auger rollers 68 on both sides rotate, they push the aerogel composite felt to both sides through the auger structure on their surface, that is, they push the surface of the aerogel composite felt from the middle to both sides, which facilitates the flattening of the aerogel composite felt. When the two toothed plates 64 move upward, they can stretch the support spring 65 and drive the rotating gear 63 to rotate through the teeth on its surface. The rotation of the rotating gear 63 drives the rotating crossbar 62 to rotate synchronously. When the two rotating crossbars 62 rotate, they drive the two pad plates 61 to move synchronously through the threaded grooves on their outer walls. The threaded grooves at corresponding positions of the two pad plates 61 are symmetrically arranged. That is, when the two pad plates 61 are under force, they slide in a state of approaching or moving away from each other. Then the two pad plates 61 move away from the bottom sides of the push box 51 together. At this time, the bottom sides of the push box 51 lose support and move downward, thereby controlling the height position of the top of the push box 51 and the bottom inner wall of the conveyor belt 3.
