Description

Technical Field

[0001] The present invention relates to the technical field of foaming devices, in particular to a TPX supercritical foaming device and a foaming method. Background Technique

[0002] A supercritical foaming device is a device that uses supercritical fluid to carry out a physical plasticization reaction in a special plasticization pressure vessel under specific pressure and temperature conditions.

[0003] After retrieval, a Chinese patent with the publication number CN111300720A discloses a vertical supercritical fluid foaming bottom-opening reaction kettle, which relates to the field of polymer material processing; its structure includes a kettle body, a kettle cover and a kettle body lifting mechanism for controlling the lifting of the kettle body; the opening of the kettle body is arranged downward, and the kettle cover is installed directly below the opening of the kettle body; the purpose of this invention is to provide a vertical supercritical fluid foaming bottom-opening reaction kettle with an upper kettle body / lower kettle cover. Compared with the traditional lower kettle body / upper kettle cover vertical device, through the design of the downward opening of the kettle body, after the supercritical fluid processing is depressurized, when the kettle body is opened upward, the material can quickly fall out of the kettle body under the action of gravity, ensuring the free foaming expansion of the material.

[0004] In the above-mentioned prior art solution, through the design of the downward opening of the kettle body, after the supercritical fluid processing is depressurized, when the kettle body is opened upward, the material can quickly fall out of the kettle body under the action of gravity, ensuring the free foaming expansion of the material. However, in the actual use process, after each foaming operation is completed, it is necessary to first take out the items falling into the kettle cover, then put the material to be foamed into the kettle cover, and then control the combination of the kettle body and the kettle cover for foaming. Since it is necessary to take out the items from the kettle cover before foaming, this step significantly reduces the foaming efficiency. Summary of the Invention

[0005] In order to solve the above technical problems, the present invention proposes a TPX supercritical foaming device and a foaming method. By moving the kettle cover up and down, the rotating ring is driven to rotate and the kettle body is synchronously replaced.

[0010] In some embodiments, clamping components are provided on the side walls of both of the two support frames. The clamping component includes: A sliding groove is formed on the side wall of the support frame. A sliding plate is slidably installed inside the sliding groove, and a clamping plate is fixedly installed on the side wall of the sliding plate.

[0011] In some embodiments, one end of the sliding groove close to the rotating ring is inclined, one end of the sliding plate close to the rotating ring is also inclined, the return spring is inclinedly distributed, and the side wall of the guiding plate is inclined.

[0012] In some embodiments, the sealing component further includes: A mounting frame is fixedly installed on the side walls of the two support frames.

[0013] In some embodiments, the receiving component further includes: There are two reinforcing rings in total.

A plurality of reinforcing rods are fixedly installed on the inner side walls of the two reinforcing rings, and the reinforcing rods are fixedly installed on the side wall of the support column.

[0014] In some embodiments, a limiting slide bar is fixedly installed on the inner side wall of the driving rod, and the limiting slide bar slidably penetrates through the side wall of the toothed plate.

[0015] A foaming method of a TPX supercritical foaming device includes the following steps: The first step: By controlling the hydraulic rod to work, the kettle cover moves downward and closely fits on the side wall of the rotating ring. Then, the material to be foamed is added into the inside of the kettle cover through the feeding pipe, and supercritical fluid is added into the inside of the kettle cover through the gas adding pipe, so that the material foams inside the kettle body and the kettle cover. Step 2: After the foaming is completed, the kettle cover is controlled by the hydraulic rod to move upward to the top, and then the kettle cover is controlled to move downward. During the downward movement of the kettle cover, the linkage component and the driven component cooperate with each other to make the rotating circle rotate a certain angle, and the adjacent kettle body is rotated to the bottom of the kettle cover. The kettle cover moves downward to fit closely with the side wall of the rotating circle; Step 3: When the foamed material moves to the position aligned with the clamping assembly, and the kettle cover moves upward, the clamping assembly clamps the side wall of the material and pulls the material downward. When the kettle cover moves downward, the clamping assembly returns to its original position, and the clamping assembly no longer clamps the side wall of the material, making it easier to remove the material. Step 4: When the kettle body after removing the material moves to the position aligned with the nozzle as the rotating circle rotates, the mold release agent is sprayed to the inside of the kettle body through the atomizing nozzle to facilitate the clamping component to remove the material from the inside of the kettle body.

[0016] Compared with the prior art, the present invention has the following significant advantages: First, the present invention adds foaming material into the interior of the kettle body through a feeding pipe, and injects supercritical fluid into the interior of the kettle body through a gas adding pipe, so that the material undergoes a foaming process inside the kettle cover and the kettle body. After the foaming is completed, the output end of the hydraulic rod is controlled to drive the hydraulic rod to move upward, and the linkage component moves together with the kettle cover, so that the material is completely exposed, and at the same time the driven component is in a meshing state. When the linkage component moves downward, the driven component drives the rotating circle to rotate a certain angle, so that the kettle cover and the kettle body are staggered, and the kettle body is replaced. The rotating circle is driven to rotate and the kettle body is replaced synchronously by moving the kettle cover up and down. Therefore, after the foaming of the material is completed, the foaming operation can be performed again immediately without waiting for the material to be taken out, thereby significantly improving the foaming efficiency; the problem of low foaming efficiency of the existing foaming device is solved.

[0017] Secondly, in the present invention, when the linkage assembly moves upward, the pressing bar will cause the two clamping assemblies to move toward the adjacent side to clamp the foamed material inside the kettle body, and the side walls of the sliding groove and the sliding plate both have a section that is inclined, and the reset spring is distributed in an inclined shape, so under the pull of the reset spring, the side wall of the sliding plate will fit with the inner wall of the sliding groove, and the clamping plate will therefore shift downward, and the material clamped by the clamping plate will detach from the inside of the kettle body during the process of the clamping plate shifting downward, thereby achieving the effect of facilitating material removal.

[0018] Thirdly, the present invention aligns the end of the nozzle away from the receiving tube with the connecting groove, so that the atomizing nozzle on the nozzle can evenly apply the release agent inside the receiving tube to the inside of the kettle body, making it easy to take out the foamed material inside the kettle body.

[0019] Fourthly, the present invention supports the inner wall of the rotating circle through the cooperation between the reinforcing ring and the reinforcing rod, thereby improving the strength of the rotating circle and reducing the possibility of deformation of the rotating circle.

[0020] Fifthly: In the present invention, by sliding the limiting slide bar through the side wall of the toothed plate, the sliding range of the toothed plate is limited by the limiting slide bar, ensuring the stability of the toothed plate during sliding and preventing the toothed plate from being displaced, which may cause the tooth block to fail to engage into the tooth groove.

Detailed Embodiments

[0023] The present invention will be described in detail below. The technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0024] The present invention provides a TPX supercritical foaming device and a foaming method by improvement. The technical solution of the present invention is as follows: As Figures 1-9As shown in the figure, a TPX supercritical foaming device includes a base 1. On the top wall surface of the base 1, two support frames 2 are fixedly installed. Between the two support frames 2, a containing component is arranged. The containing component includes a rotating ring 31, a kettle body 36 and a reinforcing ring 33. The rotating ring 31 is in a hollow cylindrical shape and is arranged between the two support frames 2. Inside the rotating ring 31, a support column 32 is arranged. At both ends of the support column 32, connecting rotating shafts 37 are fixedly installed, and the two connecting rotating shafts 37 are respectively rotatably installed inside the two support frames 2. There are multiple kettle bodies 36 in total, and the multiple kettle bodies 36 are fixedly installed on the side wall of the support column 32 at equal circumferential intervals. On the side wall of the rotating ring 31, multiple communication grooves 35 are opened, and the multiple communication grooves 35 are respectively aligned with the multiple kettle bodies 36. There are two reinforcing rings 33 in total, and the two reinforcing rings 33 are respectively fixedly installed at the two ends of the inner side wall of the rotating ring 31 that are far away from each other. On the inner side walls of the two reinforcing rings 33, multiple reinforcing rods 34 are fixedly installed, and the reinforcing rods 34 are fixedly installed on the side wall of the support column 32. Through the mutual cooperation of the reinforcing ring 33 and the reinforcing rods 34, the inner side wall of the rotating ring 31 is supported, the strength of the rotating ring 31 is improved, and the possibility of deformation of the rotating ring 31 is reduced. Between the two support frames 2, a sealing component is arranged. The sealing component includes a fixed frame 41, a kettle cover 43 and a mounting frame 46. The fixed frame 41 is fixedly installed on the top wall surface of the two support frames 2, and a hydraulic rod 42 is fixedly installed on the top wall surface of the fixed frame 41. The kettle cover 43 is located at the bottom of the fixed frame 41. The bottom end of the hydraulic rod 42 penetrates through the inside of the fixed frame 41 and is fixedly installed on the top wall surface of the kettle cover 43. A gas inlet pipe 44 is fixedly installed on the top wall surface of the kettle cover 43, and a feeding pipe 45 is fixedly installed on the top wall surface of the hydraulic rod 42. The mounting frame 46 is fixedly installed on the side walls of the two support frames 2. On the side wall of the mounting frame 46, a containing cylinder 47 is fixedly installed. Inside the containing cylinder 47, a release agent is filled. The output end of the containing cylinder 47 is fixedly installed with a spray pipe 48, and one end of the spray pipe 48 far away from the containing cylinder 47 is aligned with the adjacent communication groove 35. At one end of the spray pipe 48 far away from the containing cylinder 47, an atomizing nozzle 49 is fixedly installed. By aligning one end of the spray pipe 48 far away from the containing cylinder 47 with the communication groove 35, the atomizing nozzle 49 on the spray pipe 48 can evenly apply the release agent inside the containing cylinder 47 to the inside of the kettle body 36, which is convenient for taking out the foaming and forming materials inside the kettle body 36. On the side walls of the two support frames 2 that are far away from each other, a linkage component is arranged. The linkage component includes a linkage groove 81, a driving rod 83, a positioning rod 84 and a pressing strip 85. There are two linkage grooves 81 in total, and the two linkage grooves 81 are both opened on the side walls of the support frames 2 and are parallel to each other. Inside the two linkage grooves 81, sliding strips 82 are slidably installed. The driving rod 83 is slidably installed on the side wall of the support frame 2, and the top end of the driving rod 83 is fixedly installed at the bottom of the adjacent sliding strip 82. The positioning rod 84 is also slidably installed on the side wall of the support frame 2, and the top end of the positioning rod 84 is fixedly installed at the bottom of the adjacent sliding strip 82.The pressing strip 85 is fixedly installed at the bottom of the side wall of the driving rod 83 and the positioning rod 84 close to each other; driven components are arranged on the side walls of the two support frames 2 away from each other. The driven component includes a linkage gear 61, a tooth groove 62, a tooth plate 63, an extension spring 65, a pushing block 66 and a receiving groove 67; the linkage gear 61 is fixedly installed on the side wall of the adjacent connecting rotating shaft 37; there are multiple tooth grooves 62, and the multiple tooth grooves 62 are opened on the side wall of the driving rod 83 close to the linkage gear 61; the tooth plate 63 is slidably installed inside the driving rod 83, and multiple tooth blocks 64 are fixedly installed on the side wall of the tooth plate 63, and the tooth blocks 64 are slidably installed inside the tooth groove 62; the two ends of the extension spring 65 are respectively fixedly connected to the inner side wall of the driving rod 83 and the side wall of the tooth plate 63; the pushing block 66 is slidably installed on the inner side wall of the driving rod 83, the side wall of the pushing block 66 close to the tooth plate 63 is inclined, and a positioning strip 69 is fixedly installed on the bottom wall surface of the pushing block 66, and the positioning strip 69 is also slidably installed inside the driving rod 83; the receiving groove 67 is opened on the side wall of the driving rod 83 close to the support frame 2, and two pushing plates 68 are slidably installed inside the receiving groove 67, and the two pushing plates 68 are fixedly installed on the side wall of the support frame 2; through the extension of the output end of the hydraulic rod 42, the kettle lid 43 is tightly covered on the top of the kettle body 36, and then foaming materials are added into the kettle body 36 through the feeding pipe 45, and supercritical fluid is added into the kettle body 36 through the gas adding pipe 44, so that the materials are foamed inside the kettle lid 43 and the kettle body 36. After the foaming is completed, control the output end of the hydraulic rod 42 to drive the hydraulic rod 42 to move upward, and the linkage assembly moves together with the kettle lid 43, so that the materials are completely exposed. At this time, the pushing plate 68 sliding inside the receiving groove 67 will push the pushing block 66 downward, and the pushing block 66 pushes the tooth plate 63 and the tooth blocks 64 to extend outward, so that the tooth blocks 64 protrude outward and mesh with the linkage gear 61. Then control the output end of the hydraulic rod 42 to move downward, and the linkage assembly moves downward. The tooth blocks 64 inside the driving rod 83 will drive the linkage gear 61 and the rotating ring 31 to rotate. According to the number of kettle bodies 36, the rotating ring 31 rotates by a corresponding angle. In this solution, four kettle bodies 36 are adopted, so the rotating ring 31 rotates 90 degrees to the side away from the mounting frame 46. The receiving groove 67 at the bottom will push the positioning strip 69 upward, and under the elastic push of the extension spring 65, the tooth blocks 64 are completely retracted into the tooth groove 62, and the tooth blocks 64 no longer mesh with the linkage gear 61. When the kettle lid 43 drives the driving rod 83 to move upward, the rotating ring 31 will not rotate with the movement of the kettle lid 43, ensuring that the rotating ring 31 can only rotate in one direction. Through the up and down movement of the kettle lid 43, the rotating ring 31 rotates and the kettle body 36 is replaced at the same time. Therefore, after the materials are foamed, the foaming operation can be performed again without having to finish taking the materials before performing the foaming operation, achieving the effect of improving the foaming efficiency.;

[0025] AsFigures 1-9 As shown, in one embodiment, a clamping assembly is provided on the side walls of the two support frames 2, and the clamping assembly includes a sliding groove 51, a return spring 54 and a guide plate 56; the sliding groove 51 is opened on the side wall of the support frame 2, and the end of the sliding groove 51 close to the rotating circle 31 is inclined, and a sliding plate 52 is slidably installed inside the sliding groove 51, and the end of the sliding plate 52 close to the rotating circle 31 is also inclined, and a clamping plate 53 is fixedly installed on the side wall of the sliding plate 52; the return spring 54 is fixedly installed on the side wall of the support frame 2, and the end of the return spring 54 away from the support frame 2 is fixedly installed on the side wall of the clamping plate 53, and the return spring 54 is distributed in an inclined shape; there are two guide plates 56, and the two guide plates 56 are fixedly installed on the bottom wall of the sliding plate 52, the return spring 54 is located between the two guide plates 56, and the side wall of the guide plate 56 is inclined, and two guide grooves 55 are opened on the side wall of the support frame 2, and the guide plate 56 is slidably installed on the guide plate When the linkage assembly moves upward, the side wall of the pressing strip 85 will press against the inclined side wall of the guide plate 56, and the upward movement of the pressing strip 85 will push the guide plate 56 and the sliding plate 52 toward the inside of the base 1, so that the two clamping assemblies move toward the adjacent side to clamp the foamed material inside the kettle body 36, and the side walls of the sliding groove 51 and the sliding plate 52 both have a section that is inclined, and the return spring 54 is distributed in an inclined shape, so under the pull of the return spring 54, the side wall of the sliding plate 52 will fit with the inner side wall of the sliding groove 51, and the clamping plate 53 will therefore deviate downward, and the material clamped by the clamping plate 53 will be separated from the inside of the kettle body 36 during the process of the clamping plate 53 deviating downward, so as to achieve the effect of facilitating material removal, and when the linkage assembly moves downward, the return spring 54 pulls the clamping plate 53 to approach the support frame 2, so that the sliding plate 52, the clamping plate 53 and the guide plate 56 return to their original positions, which is convenient for the material inside the kettle body 36 to fall.

[0026] like Figures 4-7 As shown, in one embodiment, a limiting slide bar 7 is fixedly installed on the inner side wall of the driving rod 83, and the limiting slide bar 7 slides through the side wall of the tooth plate 63; by sliding the limiting slide bar 7 through the side wall of the tooth plate 63, the limiting slide bar 7 limits the sliding range of the tooth plate 63, thereby ensuring the stability of the tooth plate 63 when sliding, and avoiding the tooth plate 63 from being misaligned, resulting in the tooth block 64 being unable to be inserted into the interior of the tooth groove 62.

[0027] The present invention also discloses a foaming method of a TPX supercritical foaming device, comprising the following steps: Step 1: By controlling the hydraulic rod 42 to work, the kettle cover 43 moves downward and fits tightly against the side wall of the rotating circle 31, and then the material to be foamed is added into the kettle cover 43 through the feeding pipe 45, and the supercritical fluid is added into the kettle cover 43 through the gas adding pipe 44, so that the material is foamed inside the kettle body 36 and the kettle cover 43; Step 2: After the foaming is completed, the hydraulic rod 42 controls the kettle lid 43 to move upward to the topmost position, and then controls the kettle lid 43 to move downward. During the downward movement of the kettle lid 43, the linkage component and the driven component cooperate with each other to make the rotating ring 31 rotate by a certain angle, and the adjacent kettle body 36 is rotated to the bottom of the kettle lid 43. The kettle lid 43 moves downward and fits tightly against the side wall of the rotating ring 31. Step 3: When the foamed material moves to a position aligned with the material clamping component and the kettle lid 43 moves upward, the material clamping component clamps the side wall of the material and pulls the material downward. When the kettle lid 43 moves downward, the material clamping component returns to its original position, and the material clamping component no longer clamps the side wall of the material, facilitating material removal. Step 4: When the kettle body 36 after material removal moves to a position aligned with the spray pipe 48 as the rotating ring 31 rotates, a demoulding agent is sprayed into the interior of the kettle body 36 through the atomizing nozzle 49, facilitating the material clamping component to take out the material from the interior of the kettle body 36.

[0028] The specific working method is as follows: The output end of the hydraulic rod 42 extends to make the kettle lid 43 tightly cover the top of the kettle body 36. Then, foaming material is added into the interior of the kettle body 36 through the feeding pipe 45, and supercritical fluid is added into the interior of the kettle body 36 through the gas adding pipe 44, enabling the material to foam inside the kettle lid 43 and the kettle body 36. After the foaming is completed, the output end of the hydraulic rod 42 is controlled to drive the hydraulic rod 42 to move upward. The linkage component moves together with the kettle lid 43, making the material completely exposed. At this time, the pushing plate 68 slides inside the receiving groove 67, and the pushing plate 68 at the top will push the pushing block 66 downward. The pushing block 66 pushes the rack 63 and the tooth block 64 to extend outward, making the tooth block 64 protrude outward and mesh with the linkage gear 61. Then, the output end of the hydraulic rod 42 is controlled to move downward, and the linkage component moves downward. The tooth block 64 inside the driving rod 83 will drive the linkage gear 61 and the rotating ring 31 to rotate. According to the number of kettle bodies 36, the rotating ring 31 rotates by a corresponding angle. In this solution, four kettle bodies 36 are adopted, so the rotating ring 31 rotates 90 degrees away from the mounting frame 46. The receiving groove 67 at the bottom will push the positioning bar 69 upward, and under the elastic push of the extension spring 65, the tooth block 64 completely retracts into the tooth groove 62, and the tooth block 64 no longer meshes with the linkage gear 61. When the kettle lid 43 drives the driving rod 83 to move upward, the rotating ring 31 will not rotate with the movement of the kettle lid 43, ensuring that the rotating ring 31 can only rotate in one direction. Through the up and down movement of the kettle lid 43, the rotating ring 31 rotates while replacing the kettle body 36. Therefore, after the material foaming is completed, the foaming operation can be performed again without waiting to finish taking out the material before foaming, achieving the effect of improving the foaming efficiency.

[0029] The technical means disclosed by the solution of the present invention are not limited to those disclosed by the above technical means, but also include technical solutions composed of equivalent replacements of the above technical features. Matters not covered by the present invention are common general knowledge in the art.
