Description

Technical Field

[0001] The invention relates to the technical field of ceramic fiber blankets, and in particular to a ceramic fiber blanket preparation method and a composite high-strength ceramic fiber blanket. Background Art

[0002] Ceramic fiber is a fibrous lightweight refractory material with the advantages of light weight, high temperature resistance, good thermal stability, low thermal conductivity, small specific heat and resistance to mechanical vibration. Therefore, the ceramic fiber blanket made of it has been widely used in machinery, metallurgy, chemical industry, petroleum, ceramics, glass, electronics and other industries; ceramic fiber blanket is also called aluminum silicate fiber blanket, because one of its main components is alumina, and alumina is the main component of porcelain, so it is called ceramic fiber blanket; ceramic fiber blanket is mainly divided into ceramic fiber blowing blanket and ceramic fiber spinning blanket. Ceramic fiber spinning blanket has long fiber and small thermal conductivity, so it is better than ceramic fiber blowing blanket in thermal insulation performance. Most thermal insulation pipeline construction uses ceramic fiber spinning blanket.

[0003] The patent document with patent number CN215568980U discloses a high-temperature resistant ceramic fiber blanket, including a ceramic fiber blanket main body and a connecting positioning block, a triangular accommodating groove is provided at the top of one end of the ceramic fiber blanket main body, an interpenetrating channel is provided at a position corresponding to the triangular accommodating groove at one end of the ceramic fiber blanket main body, the interpenetrating channel is communicated with the triangular accommodating groove, the connecting positioning block includes a connecting block and a triangular anti-slipping block, the high-temperature resistant ceramic fiber blanket is reasonably designed, the triangular anti-slipping block of the connecting positioning block can pass through the interpenetrating channel on the ceramic fiber blanket main body and enter the triangular accommodating groove, and then the triangular accommodating groove in the triangular anti-slipping block is restricted therein, on the one hand, the ceramic fiber blanket main body can be pre-fixed on the high-temperature pipeline, and the gap between the ceramic fiber blanket main body and the high-temperature pipeline can be prevented from being too large, thereby improving the efficiency and effect of installation, and on the other hand, it can play a role of positioning and alignment, further improving the effect of installation.

[0004] However, in the actual production process, the inventors found that the existing ceramic fiber blankets are generally formed with matching connecting blocks and connecting grooves at both ends by a cutter after molding. This not only increases the generation of waste, causes material waste, and increases production costs, but also because the ceramic fiber blanket is prone to dislocation during molding and the ceramic fiber blanket itself has a certain deformation ability, it is easy to cause dislocation molding during molding, and then the molded connecting block and the connecting groove do not match, resulting in poor subsequent installation stability, reduced protection effect, and even defective products, resulting in a reduced yield rate. Summary of the invention

[0005] The purpose of the present invention is to address the shortcomings of the prior art. The non-standard structure of the ceramic fiber blanket is formed in a special way and supplemented by a continuous production method between each process, thereby solving the problems of large amount of waste generated in the existing ceramic fiber blanket production process, high production cost, mismatched molding structure and low yield.

[0007] Step 1: Forming process, putting the raw materials into the forming machine to form the fiber blanket body;

[0008] Step 2: In the first molding process, after a plurality of through holes penetrating both ends are formed on the fiber blanket body, a connection groove is precisely formed at a position corresponding to the through hole at one end of the fiber blanket body under the action of the through holes cooperating with the supporting structure to support and position the fiber blanket body;

[0009] Step 3: an assembly process, after taking out the waste material formed when the connecting groove is formed, the waste material is connected to the position of the fiber blanket body at one end away from the connecting groove corresponding to the through hole, so as to form a connecting block through the waste material;

[0010] Step 4: a second forming process, wherein the fiber blanket body is curled and wrapped on a support column until the connecting block is engaged with the connecting groove to form a fiber blanket roll, and a plurality of folding grooves are formed on the outer annular surface of the fiber blanket roll under the support and positioning action of the support column;

[0011] Step 5: packaging process, under the positioning effect of the support column, the fiber blanket roll is packaged in a packaging bag by a packaging machine.

[0047] Step 1: Forming process, putting the raw materials into the forming machine 2 to form the fiber blanket body 1;

[0048] Step 2: In the first molding process, after a plurality of through holes 11 penetrating both ends are formed on the fiber blanket body 1, a connection groove 12 is precisely formed at a position corresponding to the through hole 11 at one end of the fiber blanket body 1 under the action of the through hole 11 cooperating with the supporting structure to support and position the fiber blanket body 1;

[0049] Step 3: Assembling process, after taking out the waste material formed when forming the connection groove 12, the waste material is connected to the position of the fiber blanket body 1 at the end away from the connection groove 12 corresponding to the through hole 11, and the connection block 13 is formed by the waste material;

[0050] Step 4: a second forming process, wherein the fiber blanket body 1 is curled and wrapped on the support column 511 until the connecting block 13 is engaged with the connecting groove 12 to form a fiber blanket roll 10, and then a plurality of folding grooves 14 are formed on the outer annular surface of the fiber blanket roll 10 under the support and positioning effect of the support column 511;

[0051] Step 5: Packaging process: Under the positioning effect of the support column 511, the fiber blanket roll 10 is packed in a packaging bag by the packaging machine 6.

[0052] In this embodiment, after the through hole 11 is formed, the formed fiber blanket body 1 cooperates with the supporting structure to support the fiber blanket body 1 to reduce the degree of deformation thereof, so as to facilitate the precise forming of the connecting groove 12 on one end of the fiber blanket body 1, and then the waste generated by cutting the connecting groove 12 can be connected to the other end of the fiber blanket body 1 to form a connecting block 13 so that the connecting block 13 matches the shape of the connecting groove 12, thereby reducing the generation of waste. At the same time, under the positioning effect of the through hole 11, the position of the connecting groove 12 and the connecting block 13 are matched, and the matching connecting block 13 is connected to the connecting groove 12 and the fiber blanket body 1 is wrapped on the supporting column 511 to form a fiber blanket roll 10, which can not only check whether the production of the connecting block 13 and the connecting groove 12 is unqualified, but also facilitate the forming of multiple folding grooves 14 on the outer annular surface of the fiber blanket roll 10.

[0053] It should be noted that the present application does not limit the specific structure of the above-mentioned support structure. The following provides a preferred structure to implement this method:

[0054] In detail, the above-mentioned support structure can be completed by using the first cutter 361 and the second cutter 363 of the first molding component 36 in the third embodiment. The first cutter and the second cutter cooperate with each other to cut a through hole and are inserted into the through hole to support the fiber blanket body.

[0055] Embodiment 2

[0056] like Figure 1-Figure 4 As shown, the present application also discloses a composite high-strength ceramic fiber blanket prepared based on the above-mentioned ceramic fiber blanket preparation method, comprising a fiber blanket body 1, a plurality of through holes 11 formed through both ends of the fiber blanket body 1, a connecting groove 12 formed at one end of the fiber blanket body 1 at a position corresponding to the through hole 11, a connecting block 13 arranged at the other end of the fiber blanket body 1 at a position corresponding to the through hole 11 and used for clamping the connecting groove 12, and a plurality of folding grooves 14 formed at intervals on one side of the fiber blanket body 1.

[0057] In this embodiment, the through hole 11 is provided to facilitate the forming and positioning of the connecting groove 12 and the connecting block 13 . At the same time, the folding groove 14 is used to facilitate wrapping the fiber blanket body 1 outside the pipe, thereby facilitating the connection of the connecting groove 12 to the connecting block 13 .

[0058] Further, if Figure 1As shown, the molding raw material ratio of the fiber blanket body 1 is 35%-49% of alumina, 40%-53% of quartz sand, and 0%-25% of zircon sand; the classification temperature of the fiber blanket body 1 is 1400℃-1460℃, and the continuous use temperature of the fiber blanket body 1 is 1300℃-1400℃; the density of the fiber blanket body 1 is 160kg / m³-240kg / m³; and the thickness of the fiber blanket body 1 is 150mm-350mm.

[0060] In this embodiment, the heat absorbing material 15 of alkali metal salt is arranged in the through hole 11 to improve the high temperature resistance of the fiber blanket body 1 .

[0061] In detail, when the fiber blanket body 1 is heated, the heat absorbing material 15 melts and absorbs a large amount of heat, thereby improving the high temperature resistance effect. When the fiber blanket body 1 is cooled, the heat absorbing material 15 releases heat and solidifies, so that the fiber blanket body 1 can absorb heat the next time it is heated.

[0063] In this embodiment, sealing columns 16 and connecting columns 17 are provided to connect and seal the two ends of the through hole 11 to prevent the heat absorbing material 15 from leaking out. Meanwhile, the connecting columns 17 improve the stability of the connection between the connecting block 13 and the fiber blanket body 1 .

[0064] Further, if Figure 3-Figure 4 As shown, the connecting block 13 includes an inserting portion 131 of a trapezoidal structure and a snap-fitting portion 132 arranged on one side of the lower bottom of the inserting portion 131 corresponding to the trapezoidal structure. Correspondingly, the connecting groove 12 includes an inserting channel 121 adapted to the inserting portion 131 and a snap-fitting channel 122 adapted to the snap-fitting portion 132.

[0065] In this embodiment, by providing the insertion portion 131 with a trapezoidal structure, the engaging portion 132 is conveniently engaged with the engaging channel 122 after the insertion portion 131 is inserted into the insertion channel 121 .

[0066] In detail, when in use, under the guiding action of the inclined structure of the insertion part 131, the clamping part 132 is conveniently inserted into the insertion channel 121 along with the insertion part 131, and the insertion channel 121 squeezes the clamping part 132 and the insertion part 131 to deform. When the clamping part 132 is inserted into the insertion channel 121 along with the insertion part 131, the clamping part 132 and the insertion part 131 restore their deformation, and the clamping part 132 is clamped in the clamping channel 122 to realize the connection between the connecting block 13 and the connecting groove 12.

[0067] Embodiment 3

[0068] like Figure 5 As shown, the present application also discloses a ceramic fiber blanket preparation device based on the above-mentioned ceramic fiber blanket preparation method and used for preparing the above-mentioned composite high-strength ceramic fiber blanket, including a molding machine 2 for molding a fiber blanket body 1, a first molding mechanism 3, an assembling mechanism 4, a second molding mechanism 5 and a packaging machine 6 arranged in sequence behind the discharge end of the molding machine 2; the first molding mechanism 3 is used to mold a plurality of through holes 11 on the fiber blanket body 1 and support and position the fiber blanket body 1 through the through holes 11, and then mold a connecting groove 12 at a position corresponding to the through hole 11 at one end of the fiber blanket body 1; the assembling mechanism 4 is used to assemble the waste formed by the connecting groove 12 molded by the first molding mechanism 3 at a position corresponding to the through hole 11 at one end of the fiber blanket body 1 away from the connecting groove 12, so that the waste forms a connecting block 13; the second molding mechanism 5 is used to position the fiber blanket body 1 and mold a plurality of folding grooves 14 on one side of the fiber blanket body 1; the packaging machine 6 is used to pack the fiber blanket body 1 positioned by the second molding mechanism 5 into a bag.

[0069] In this embodiment, by setting a molding machine 2 to cooperate with a first molding mechanism 3, an assembling mechanism 4, a second molding mechanism 5 and a packaging machine 6, the molding process, the first molding process, the assembling process, the second molding process and the packaging process in the production process of a composite high-strength ceramic fiber blanket are successively realized, thereby realizing mechanical automated production with high production efficiency and avoiding manual interference, further improving the matching degree of the shape and position of the molded connecting block 13 and the connecting groove 12.

[0070] It should be noted that the forming machine 2 and the packaging machine 6 themselves and their installation methods are all existing technologies and will not be described in detail here.

[0071] Further, if Figure 6-Figure 12 as well as Figure 18-Figure 20As shown, the first molding mechanism 3 includes a support platform 31 arranged at the discharge end of the molding machine 2, a first positioning plate 32 rotatably arranged on the support platform 31 and used to position the fiber blanket body 1 away from the molding machine 2, a second positioning plate 33 rotatably arranged on the support platform 31 and used to push the fiber blanket body 1 formed by the molding machine 2 to abut against the first positioning plate 32, third positioning plates 34 movably arranged on the outer sides of the two ends of the first positioning plate 32 on the support platform 31 and cooperate with the first positioning plate 32 and the second positioning plate 33 to form a positioning area, two first pressing plates 35 movably arranged on the two third positioning plates 34 and used to press the fiber blanket body 1 in the positioning area, a first molding component 36 arranged on the support platform 31 and used to cooperate with the through hole 11 to support the fiber blanket body 1 after the through hole 11 is formed, and a second molding component 37 arranged on the support platform 31 and used to form the connecting groove 12.

[0072] In this embodiment, after positioning the fiber blanket body 1 by providing a support platform 31 in cooperation with the first positioning plate 32 , the second positioning plate 33 , the third positioning plate 34 and the first pressing plate 35 , it is convenient for the first molding mechanism 3 and the second molding mechanism 5 to mold the through hole 11 and the connecting groove 12 .

[0073] In detail, when in use, first, the molding machine 2 conveys one end of the molded fiber blanket body 1 to the positioning area on the support platform 31, and then the second positioning plate 33 rotates to push the fiber blanket body 1 to abut against the first positioning plate 32, and cooperates with the two third positioning plates 34 to move and clamp the fiber blanket body 1 in the positioning area, and then the first pressing plate 35 moves downward to press the fiber blanket body 1 in the positioning area to prevent the fiber blanket body 1 from being misplaced when the first molding component 36 moves the molding through hole 11. Finally, under the action of the first molding component 36 cooperating with the through hole 11 to support the fiber blanket, the second molding component 37 accurately molds the connecting groove 12, and then the first molding component 36 and the second molding component 37 withdraw from the fiber blanket body 1.

[0074] It should be noted that one end of the third positioning plate 34 close to the second positioning plate 33 is bent outward to form a guide portion 341, and the two third positioning plates 34 are both formed with a first clearance gap 342 for avoiding the first molding component 36; one of the two first pressing plates 35 is formed with a second clearance gap 351 for avoiding the second molding component 37.

[0075] Further, if Figure 9-12As shown, the first molding assembly 36 includes a plurality of first cutters 361 movably disposed on one side of the support platform 31, a plurality of positioning posts 362 movably disposed on the other side of the support platform 31, a second cutter 363 disposed on the positioning posts 362 and cooperating with the first cutter 361 to form a through hole 11 on the fiber blanket body 1, a first push plate 364 movably disposed on the positioning posts 362 and used to push out the waste in the second cutter 363, and a glue outlet channel disposed in the positioning posts 362 and extending to the outside of the first cutter 361. 365 and a discharge channel 366; when forming the connecting groove 12, the first cutter 361 and the second cutter 363 support and form a gap to avoid the second molding component 37; when forming the connecting groove 12, in the process of the first cutter 361 withdrawing from the through hole 11, the waste material in the first cutter 361 cooperates with the first push plate 364 and the adhesive extruded from the adhesive discharge channel 365 to bond in the through hole 11 near one end of the connecting groove 12 to form a sealing column 16, and then the discharge channel 366 squeezes the heat-absorbing material 15 into the through hole 11.

[0076] In this embodiment, after the first cutter 361 is arranged to cooperate with the second cutter 363 to form the through hole 11, the positioning column 362 is cooperated so that the first cutter 361 and the second cutter 363 cooperate with the through hole 11 to support and position one end of the fiber blanket body 1 to form the connecting groove 12. After the second molding component 37 forms the connecting groove 12, the second cutter 363 cooperates with the first push plate 364 and the glue outlet channel 365 during the process of withdrawing from the through hole 11, so that the waste material in the second cutter 363 is bonded to the through hole 11 near one end of the connecting groove 12 to form a sealing column 16, which is convenient for the installation of the sealing column 16 and further reduces the generation of waste material, and cooperates with the discharge channel 366 to fill the through hole 11 with the heat-absorbing material 15.

[0077] In detail, when in use, the first cutter 361 and the second cutter 363 are first inserted into the two sides of the fiber blanket body 1 through the first clearance notches 342 on the two third positioning plates 34 until the first cutter 361 and the second cutter 363 contact to form the through hole 11, and then the second cutter 363 moves to one end of the fiber blanket body 1 along with the first cutter 361 under the extension of the positioning column 362, so that a gap is formed between the second cutter 363 and the first cutter 361 to avoid the second forming component 37. Then, when the second molding component 37 molds the connecting groove 12, the waste material between the first cutter 361 and the second cutter 363 is cut off, so that waste material remains in the second cutter 363. Finally, when the second cutter 363 exits the through hole 11 along with the positioning column 362, the glue outlet channel 365 smears glue on the inner wall of one end of the through hole 11, and at the same time cooperates with the push plate to push out the waste material in the second cutter 363 and glue it in the through hole 11 through the glue, and then the heat-absorbing material 15 is filled into the through hole 11 through the discharge channel 366.

[0078] It should be noted that the first cutter 361 is a structure with two ends connected, and the waste inside it is squeezed out by new waste in the next molding process, so that the function of automatically discharging waste is achieved, which is convenient to use;

[0079] In addition, the glue and the heat-absorbing material 15 are squeezed out from the glue outlet channel 365 and the material outlet channel 366 respectively by negative pressure equipment such as a pump. This is the prior art, and the specific structure is not shown in the drawings, so it will not be described in detail here.

[0081] In this embodiment, the connection groove 12 and the connection block 13 are formed by installing a mounting frame 371 to install a movable third cutter 372 and a fifth cutter 374 , and cooperating with a movable fourth cutter 373 disposed on the support platform 31 .

[0082] In detail, when in use, first, the third cutter 372 and the fifth cutter 374 move with the mounting frame 371 to directly above the corresponding through hole 11 of the fiber blanket body 1, and then the third cutter 372 moves downward and is inserted into the fiber blanket body 1 to form the upper inclined surface structure of the insertion part 131 and cut off the waste between the first cutter 361 and the second cutter 363, and then the fourth cutter 373 moves and is inserted into one side of the fiber blanket body 1 until it contacts the third cutter 372 and then cuts out the insertion part 131, and finally the fifth cutter 374 moves downward and is inserted into the fiber blanket body 1 until it contacts the third cutter 372 and the fourth cutter 373 and then cuts out the clamping part 132, thereby forming the connecting groove 12 and the connecting block 13.

[0083] Further, if Figure 13-Figure 15 as well as Figure 20-21As shown, the assembling mechanism 4 includes a second pressing plate 41 movably arranged on the mounting frame 371 and used for pressing the clamping portion 132 out of the clamping channel 122, a first positioning pin 42, a second positioning pin 43 and a sixth cutter 44 movably arranged on the support platform 31; the first positioning pin 42 is used to be inserted into the waste material inside the connecting block 13 and the first cutter 361, so that when the first cutter 361 is moved out of the connecting block 13, its internal waste material is connected to the connecting block 13; the second positioning pin 43 is used to position the waste material inside the first cutter 361, so that when the second cutter 363 is inserted into the connecting block 13, the waste material inside the connecting block 13 is connected to the inside of the second cutter 363; the sixth cutter 44 is used to shape the waste material inside the first cutter 361, so that the waste material inside the connecting block 13 forms a connecting column 17.

[0084] In this embodiment, after the connecting block 13 is taken out of the connecting groove 12 by setting the second pressing plate 41 to press the clamping portion 132 to disengage the clamping channel 122, the first positioning needle 42 and the second positioning needle 43 are used to facilitate the insertion and positioning of the connecting block 13 and the waste in the first cutter 361, so that after the first cutter 361 withdraws from the connecting block 13, the second cutter 363 can be inserted into the connecting block 13, and then the sixth cutter 44 is used to shape the waste in the first cutter 361 so that the waste in the connecting block 13 forms the connecting column 17, and then the second cutter 363 can be reinserted into the through hole 11, so as to further reduce the generation of waste and facilitate the insertion of the connecting column 17 into the through hole 11 with the second cutter 363. Then, in the process of the withdrawal of the second cutter 363, the first push plate 364 glue outlet channel 365 is used to assist in realizing the connection between the connecting column 17 and the connecting block 13 and the fiber blanket body 1.

[0085] In detail, when in use, first, the second pressing plate 41 moves with the mounting bracket 371 to the top of the connecting channel, and then the second pressing plate 41 moves downward to press the clamping portion 132 out of the clamping channel 122 and cooperates with the first cutter 361 to move out of the connecting groove 12 to separate the connecting block 13 from the connecting groove 12. Then, after the first positioning pin 42 is inserted into the connecting block 13 and the waste in the first cutter 361, the first cutter 361 is moved out of the connecting block 13, and the waste in the first cutter 361 is connected to the connecting block 13. Then, the first positioning pin 42 is inserted into the connecting block 13 and cooperates with the second positioning pin 43 to insert the first cutter 361 and the connecting block 13. After the waste material between the first cutter 361 and the connecting block 13 is removed, the sixth cutter 44 is able to shape the waste material between the first cutter 361 and the connecting block 13 so that the waste material in the connecting block 13 forms a connecting column 17, and the second cutter 363 is able to be inserted into the connecting block 13 and the connecting column 17 is connected to the second cutter 363. Finally, the connecting column 17 moves with the second cutter 363 and is inserted into the through hole 11. In the process of the second cutter 363 withdrawing from the through hole 11, the glue outlet channel 365 is cooperated to apply glue in the through hole 11 and the connecting block 13, and the first push plate 364 pushes the connecting column 17 in the second cutter 363 out, so that the connecting column 17 is connected to the through hole 11 and the connecting block 13 to realize the connection between the three.

[0086] It should be noted that a glue outlet pipe 46 is provided on the outer side of the sixth cutter 44. The glue outlet pipe 46 is used to apply glue to the side of the connecting block 13 close to the first cutter 361 during the process of forming the waste between the first cutter 361 and the connecting block 13 along with the sixth cutter 44. This makes it possible for the connecting block 13 to adhere to the fiber blanket body 1 when the connecting column 17 is connected to the through hole 11 along with the second cutter 363, so as to facilitate the subsequent withdrawal of the second cutter 363 and improve the stability of the connection between the connecting block 13 and the fiber blanket body 1.

[0087] Further, if Figure 1-Figure 2 , Figure 16-Figure 17 as well as Figure 21-23 As shown, the second forming mechanism 5 includes a supporting assembly 51 arranged on the supporting platform 31 and used to support and position the fiber blanket body 1 rolled into a fiber blanket roll 10, a fourth positioning plate arranged on the supporting platform 31 and used to position the fiber blanket body 1 directly above the supporting assembly 51, and a third forming assembly 52 arranged on the supporting platform 31 and used to form a folding groove 14 on the outer side of the fiber blanket roll 10.

[0088] In this embodiment, the fiber blanket body 1 is positioned by setting a support component 51 in cooperation with the fourth positioning plate and then rolled into a fiber blanket roll 10 for support and positioning, and then the folding groove 14 is formed on the outer side of the fiber blanket roll 10 in cooperation with the third molding component 52 (that is, the folding groove 14 is formed on one side of the fiber blanket body 1).

[0089] It should be noted that when the first positioning plate 32 rotates to open the positioning area, the two third positioning plates 34 move to clamp the fiber blanket body 1 and move the fiber blanket body 1 out of the positioning area until it abuts against the fourth positioning plate, and the fiber blanket body 1 is located directly above the support column 511.

[0090] Further, if Figure 1-Figure 2 as well as Figure 16-Figure 17 As shown, the support assembly 51 includes a support column 511 which is movably arranged on the support platform 31 and is used to push the fiber blanket body 1 to move upward, two push rods 512 which are opened and closed on the support platform 31 and are used to push the two ends of the fiber blanket body 1 to bend and wrap around the support column 511, and an arc-shaped extrusion plate 513 which is movably arranged on the support platform 31 and is used to squeeze the two ends of the fiber blanket body 1 wrapped on the support column 511 until the connecting block 13 is engaged with the connecting groove 12.

[0091] In this embodiment, a movable support column 511 is provided in cooperation with two opening and closing push rods 512 so that the fiber blanket body 1 can be wrapped around the support column 511, and then the arc-shaped extrusion plate 513 is cooperated to squeeze and bend the two ends of the fiber blanket body 1 wrapped around the support column 511 until the connecting block 13 is snapped into the connecting groove 12.

[0092] In detail, when in use, first, the two pushing rods 512 are opened, and the support column 511 pushes the fiber blanket body 1 upward so that its two ends are pushed and bent by the two pushing rods 512. Then, in the process of the support column 511 moving upward, the two pushing rods 512 are gradually closed, thereby pushing the two ends of the fiber blanket body 1 to curl on the support column 511. Finally, after the fiber blanket body 1 is positioned on the support column 511 by the push of the pushing rods 512, the arc-shaped extrusion plate 513 is moved upward to squeeze the two ends of the fiber blanket body 1 to bend until the arc-shaped extrusion plate 513 fits against the support column 511, and the connecting block 13 is connected to the connecting groove 12.

[0093] It should be noted that the support column 511 is rotatably arranged on the support platform 31. After the third forming assembly 52 forms the folding groove 14, the fiber blanket roll 10 rotates with the support column 511 to the packaging machine 6 outside the support platform 31, and then is packaged by the packaging machine 6.

[0094] Further, if Figure 1-Figure 2 as well as Figure 16-Figure 17 As shown, the third forming assembly 52 includes an extrusion sleeve 521 movably disposed on the support platform 31, a guide structure 522 disposed at one end of the extrusion sleeve 521 and used to guide the fiber blanket roll 10 to slide into the extrusion sleeve 521, and a plurality of seventh cutters 523 disposed on the inner wall of the extrusion sleeve 521 at intervals along the circumference of the fiber blanket roll 10.

[0095] In this embodiment, the extrusion sleeve 521 is provided to cooperate with the guide structure 522, so that the fiber blanket roll 10 can be easily inserted into the extrusion sleeve 521 for extrusion positioning, thereby preventing the seventh cutter 523 from deforming and moving out of position during molding, which may cause molding dislocation.

[0096] It should be noted that the internal channel of the seventh cutter 523 passes through the outside of the end of the extrusion sleeve 521 away from the support column 511, and the waste inside is squeezed out by new waste during the next molding process, thereby achieving the function of automatically discharging waste and being easy to use.
