Description

Technical Field

[0001] This invention relates to the field of continuous foaming technology, and more specifically to a multi-component continuous foaming production line. Background Technology

[0002] The density of polyurethane board products ranges from 35 to 300 kg / m³. 3 This is a rigid foam insulation material made by mixing and pouring multi-component materials onto fiberglass cloth to form a foam. The product is suitable for various occasions requiring thermal insulation and heat insulation, and the applicable temperature range is 80-250℃.

[0003] The prior art, authorized on October 21, 2022, patent CN113927813B, discloses a non-standard equipment for a continuous foaming production line of polyurethane boards. This non-standard equipment, along the material production direction, includes a four-sided packaging section, an injection section, a pressing section, a separation section, and a cutting section. The disadvantages of this structure are as follows:

[0004] 1. The four-sided unwinding section forms a foaming cavity with left and right side paper, upper surface paper and bottom fiberglass cloth. However, since the side paper and surface paper need to be separated later, wrapping too much side paper will increase the difficulty and efficiency of the separation process.

[0005] 2. The pressing process has limited shaping and curing effects, lacking both heating and shaping processes, which reduces the final product quality of the polyurethane board.

[0006] 3. The existing cutting section has poor versatility and cannot guarantee the synchronization of cutting while the material is being transported forward. It is necessary to stop the cutting process to cut the material and then transport it again, which reduces the overall production efficiency of the foaming production line.

[0007] To address these issues, we offer a multi-component continuous foaming production line. Summary of the Invention

[0008] To address the problems existing in the prior art, this invention provides a multi-component continuous foaming production line, which realizes foaming production under reasonable unwinding conditions, reduces the difficulty of the separation process, adds heating and shaping and heating and curing structures to the pressing section to improve the finished product effect of polyurethane boards, and adopts a follow-up cutting structure in the cutting section to ensure the cutting action of materials during the conveying process, thereby greatly improving the production efficiency of the foaming production line.

[0009] To achieve the above objectives, the present invention employs a multi-component continuous foaming production line, which comprises the following components arranged sequentially along the material travel direction:

[0010] The first unwinding mechanism is used to unwind the lower layer of kraft paper and the glass fiber.

[0011] Specifically, the first unwinding mechanism includes a material feeding platform, a kraft paper guide roller, a front-end guide assembly, and a fiberglass unwinding unit. The material feeding platform is equipped with a material conveying section. The kraft paper guide roller, the fiberglass unwinding unit, and the fiberglass pressing assembly are arranged sequentially along the conveying path of the conveying section, wherein:

[0012] The kraft paper guide roller includes a first unwinding seat, a first air shaft, a first power component, and a lower kraft paper roll. The first unwinding seat is equipped with a rotatable first air shaft, and the lower kraft paper roll is wound around the first air shaft. The first power component provides rotational power to the first air shaft and drives the lower kraft paper roll to perform an unwinding action.

[0013] The number of fiberglass unwinding units is at least three and they are installed on the path of the lower kraft paper, and some or all of the fiberglass unwinding units are laid on the lower kraft paper.

[0014] Preferably, the number of the above-mentioned fiberglass unwinding units is designed to be more than twenty. The staff can combine them arbitrarily according to the actual situation. For example, four fiberglass unwinding units are grouped together, and the staff selects four of them to carry out the fiberglass unwinding work, so as to improve the universality and unwinding effect in the initial unwinding process.

[0015] The fiberglass pressing assembly includes a fixed frame designed at the tail end of the feeding platform and a pressing block installed on the fixed frame. The pressing block compresses the fiberglass and the underlying kraft paper. Through the compression work of the fiberglass pressing assembly, the bonding effect between the fiberglass and the underlying kraft paper is strengthened.

[0016] A material feeding machine is used to fill materials.

[0017] As a further optimization of the above solution, the fabric feeding machine includes a fabric feeding platform and an injection tool. The extruded glass fiber and the lower kraft paper form the material to be injected and are transported to the fabric feeding platform. The injection end of the injection tool is located above the material to be injected and is filled with the material under the action of the power source.

[0018] The second unwinding mechanism is used to unwind the upper layer of kraft paper.

[0019] The second unwinding mechanism includes a second unwinding seat, a second air shaft, a second power component, and an upper kraft paper roll. The second unwinding seat is equipped with a rotatable second air shaft, and the upper kraft paper roll is wound around the second air shaft. The second power component provides rotational power to the second air shaft and drives the upper kraft paper roll to perform an unwinding action.

[0020] A shaping conveyor line is used to heat and shape materials.

[0021] The forming conveyor line includes a frame, a bottom tracked conveyor line, a side tracked conveyor line, a first steam heating system, and a pressing roller trolley;

[0022] The frame is equipped with a bottom tracked conveyor for conveying filling materials and side tracked conveyors extending in the direction of material movement to cooperate with the bottom tracked conveyor. The two side tracked conveyors restrict the two sides of the filling materials. The first steam heating system is located on the same vertical plane as the pressing roller trolley and provides hot air for the filling materials. The pressing roller trolley is installed on the entrance side of the frame and presses down the filling materials under the drive of the power source.

[0023] As a further optimization of the above solution, the aforementioned pressing roller trolley includes a mounting frame installed on a frame body. Below the mounting frame are staggered first pressing roller assemblies and second pressing roller assemblies. The power source is a third power component, which provides power to the first and second pressing roller assemblies and drives them to move vertically up and down. Both the first and second pressing roller assemblies are connected to racks. The two racks move in opposite directions under the drive of gears to drive the first and second pressing roller assemblies to move in opposite directions. A fourth power component provides power to the gears and drives them to rotate. By staggering the double pressing roller structure, the pressing effect is maximized. Under the action of the gear and rack, the width of the double pressing roller structure can be adjusted to ensure rolling of materials of different widths and improve the rolling effect of the pressing roller trolley.

[0024] Drying ovens are used to heat and solidify materials.

[0025] The drying room includes a heating space and a conveying device that runs through both ends of the heating space. The bottom and both sides of the heating space are equipped with a second steam heating system, which provides hot air to the bottom and both sides of the heating space.

[0026] Transition line, used to achieve room temperature cooling of materials;

[0027] The follow-up cutting station is used to realize the follow-up cutting of materials.

[0028] As a further optimization of the above solution, the follow-up cutting station includes a cutting platform and a follow-up base. The workpiece to be cut is conveyed to the cutting platform and moves synchronously with the cured material under the drive of the follow-up base. One reciprocating motion of the cutting platform completes the cutting and moving action of a cured material.

[0029] As a further optimization of the above solution, the cutting platform includes a cutting saw mounted on the cutting platform. The cutting saw has an arc-shaped receiving space for the saw blade to enter. The side of the cutting saw away from the workpiece to be cut is the driving side and the other side is the cutting side. The driving wheel is arranged on the driving side and two driven wheels are arranged on the cutting side. The saw blade passes through the driving wheel and the two driven wheels to form a closed cutting saw structure. The fifth power unit is the power source of the driving wheel and drives the driving wheel to rotate so that the saw blade moves around the shape of the cutting saw structure.

[0030] The aforementioned structure enhances the versatility of the cutting process, ensuring the synchronization of cutting while the material is being transported forward, thereby improving the overall production efficiency of the foaming production line and enabling one-time cutting while the material is being transported.

[0031] The multi-component continuous foaming production process includes the following steps:

[0032] The initial unwinding is used to unwind the lower layer of kraft paper and the glass fiber, and to obtain the material to be filled.

[0033] Fabric, used to fill the material to be filled and to obtain the filled material;

[0034] Secondary unwinding is used to unwind the upper kraft paper and lay it on the filling fabric to obtain the material to be shaped.

[0035] Heating and shaping is used to heat and shape materials to be shaped while in a conveying state, and to obtain the shaped material.

[0036] Heat curing is used to heat-cur materials after shaping and to obtain cured materials.

[0037] Room temperature cooling is used to cool the cured material at room temperature and obtain the cooled material.

[0038] Follow-up cutting is used to complete the cutting work while the material moves after follow-up cooling, and to obtain the cut material.

[0039] The multi-component continuous foaming production line of the present invention has the following beneficial effects:

[0040] 1. The multi-component continuous foaming production line of the present invention realizes foaming production under reasonable unwinding state, reduces the difficulty of separation process, adds heating and shaping and heating and curing structure to the pressing part to improve the finished product effect of polyurethane board, and adopts follow-up cutting structure in the cutting part to ensure the cutting action of material during the conveying process, which greatly improves the production efficiency of foaming production line.

[0041] 2. The multi-component continuous foaming production line of the present invention designs the number of the above-mentioned glass fiber unwinding units to be multiple, and the staff can combine them arbitrarily according to the actual situation. For example, four glass fiber unwinding units are a group, and the staff selects four glass fiber unwinding units to perform glass fiber unwinding work, so as to improve the universality and unwinding effect in the initial unwinding process.

[0042] 3. The multi-component continuous foaming production line of the present invention is designed with a staggered double pressing roller structure to maximize the pressing effect. Under the action of gear and rack, the width of the double pressing roller structure can be adjusted to ensure rolling of materials of different widths and improve the rolling effect of the pressing roller trolley.

[0043] 4. The multi-component continuous foaming production line of the present invention enhances the versatility of the cutting process, ensuring the cutting synchronization of the cutting material while it is being transported forward, thereby improving the overall production efficiency of the foaming production line and realizing one-time cutting while the cutting material is being transported.

[0061] Please refer to the instruction manual appendix. Figure 1-12 This invention provides a technical solution: a multi-component continuous foaming production line, which includes components arranged sequentially along the material travel direction:

[0062] The first unwinding mechanism 1 is used to unwind the lower layer of kraft paper and the glass fiber.

[0063] In detail, the first unwinding mechanism 1 includes a material feeding platform 11, a kraft paper guide roller 12, a front-end guide assembly 13, and a fiberglass unwinding unit 14. The material feeding platform 11 is provided with a material conveying section 111. The kraft paper guide roller 12, the fiberglass unwinding unit 14, and the fiberglass pressing assembly 15 are arranged sequentially along the conveying path of the conveying section 111, wherein:

[0064] For example, the conveying section 111 mentioned above adopts a tracked conveyor line. The tracked conveyor line is assembled by using two non-standard chains with several irregularly shaped aluminum profiles in the middle. Using aluminum profiles helps to reduce the weight of the system and increase the conveying distance. Both non-standard chains are equipped with sprockets, one of which is a drive wheel 76. A drive wheel 76 drive motor is installed on the drive wheel 76. The drive wheel 76 drive motor drives the drive wheel 76 to rotate. The rotation of the drive wheel 76 drives the non-standard chain to move, thereby realizing the movement of the entire tracked conveyor line.

[0065] The kraft paper guide roller 12 includes a first unwinding seat 121, a first air shaft 122, a first power component 123, and a lower kraft paper roll. The first unwinding seat 121 is equipped with a rotatable first air shaft 122, and the lower kraft paper roll is wound around the first air shaft 122. The first power component 123 provides rotational power to the first air shaft 122 and drives the lower kraft paper roll to perform an unwinding action.

[0066] Furthermore, the first power component 123 is an air shaft motor, which drives the first air shaft 122 to rotate, thereby realizing the rotation of the first air shaft 122. The rotation of the first air shaft 122 realizes the unwinding action of the lower kraft paper roll, so as to place the lower kraft paper on the material feeding platform 11 and convey the lower kraft paper under the action of the conveying part 111. Of course, the first power component 123 can also be a manual structure.

[0067] Furthermore, in some examples, the first power component 123 is a handwheel. By rotating the handwheel, the operator can rotate the first air shaft 122 to achieve the rotation of the first air shaft 122. The rotation of the first air shaft 122 enables the unwinding of the lower kraft paper roll, so that the lower kraft paper is placed on the material feeding platform 11 and conveyed by the conveying part 111.

[0068] The number of fiberglass unwinding units 14 is at least three and they are installed on the path of the lower kraft paper and some or all of the fiberglass unwinding units 14 are laid on the lower kraft paper.

[0069] Preferably, the number of the above-mentioned fiberglass unwinding units 14 is designed to be more than twenty. The staff can combine them arbitrarily according to the actual situation. For example, four fiberglass unwinding units 14 are grouped together, and the staff selects four of them to carry out the fiberglass unwinding work, so as to improve the universality and unwinding effect in the initial unwinding process.

[0070] Preferably, in this embodiment, the number of the above-mentioned fiberglass unwinding units 14 is designed to be twenty-four, and they are arranged in an alternating manner, for example, twelve fiberglass unwinding units 14 are used at the top and twelve fiberglass unwinding units 14 are used at the bottom. In the actual unwinding process, the operator can select any number of fiberglass unwinding units 14 to perform the fiberglass unwinding work, so as to improve the universality and unwinding effect in the initial unwinding process.

[0071] The fiberglass pressing assembly 15 includes a fixed frame 151 designed at the tail end of the feeding platform 11 and a pressing block 152 installed on the fixed frame 151. The pressing block 152 squeezes the fiberglass and the lower kraft paper. Through the squeezing operation of the fiberglass pressing assembly 15, the bonding effect between the fiberglass and the lower kraft paper is strengthened.

[0072] In detail, in this embodiment, the above-mentioned pressure block 152 structure adopts a pressure block 152 with an arc-shaped bottom surface, and the flat pressure structure is replaced by a rolling structure to reduce the impact of the rolling structure on the material.

[0073] Preferably, some structures involve an adjustable structure for raising and lowering the pressure block 152, such as a threaded seat or a screw structure. The screw is connected to the fixed frame 151, and the nut seat is threadedly connected to the screw and is fixedly connected to the pressure block 152. A handwheel is installed on the screw structure. By rotating the handwheel, the operator can rotate the screw, thereby driving the nut seat to move linearly along the screw, so as to realize the vertical movement of the pressure block 152. This allows the pressure block 152 to adapt to materials of different heights. Of course, the adjustment structure can also be an electric telescopic rod or other structures.

[0074] Fabric feeder 2 is used to fill materials.

[0075] As a further optimization of the above solution, the fabric feeding machine 2 includes a fabric feeding platform 21 and a material injection tool 22. The extruded glass fiber and the lower kraft paper form the material to be injected and are conveyed to the fabric feeding platform 21. The injection end of the material injection tool 22 is located above the material to be injected and is filled with the material under the action of the power source, and the size of the material is limited under the action of the material to be injected.

[0076] Furthermore, in this embodiment, the fabric platform 21 receives the first unwinding mechanism 1, and after the first unwinding mechanism 1 unwinds the fabric, the fabric platform 21 is also provided with a transport section.

[0077] For example, the conveying section 111 mentioned above adopts a tracked conveyor line. The tracked conveyor line is assembled by using two non-standard chains with several irregularly shaped aluminum profiles in the middle. Using aluminum profiles helps to reduce the weight of the system and increase the conveying distance. Both non-standard chains are equipped with sprockets, one of which is a drive wheel 76. A drive wheel 76 drive motor is installed on the drive wheel 76. The drive wheel 76 drive motor drives the drive wheel 76 to rotate. The rotation of the drive wheel 76 drives the non-standard chain to move, thereby realizing the movement of the entire tracked conveyor line.

[0078] Furthermore, to enhance the filling effect, the non-standard equipment in this embodiment is also equipped with a limiting structure for restricting the width of the material. For example, the width adjustment device includes a transverse screw with a left-hand rotating part and a right-hand rotating part. Both the left-hand rotating part and the right-hand rotating part are equipped with moving blocks. A power source that provides power to the transverse screw drives the two moving blocks to move in opposite directions or in opposite directions. Preferably, in this embodiment, the power source adopts a handwheel structure. The operator rotates the handwheel to realize the rotation of the transverse screw, thereby driving the two moving blocks to move in opposite directions or in opposite directions, so as to adjust the distance between the two moving blocks, thereby achieving the purpose of limiting the width of the material and ensuring the width of the material in the next process.

[0079] The second unwinding mechanism 3 is used to unwind the upper layer of kraft paper.

[0080] The second unwinding mechanism 3 includes a second unwinding seat 31, a second air shaft 32, a second power component 33, and an upper kraft paper roll 34. The second unwinding seat 31 is equipped with a rotatable second air shaft 32, and the upper kraft paper roll 34 is wound around the second air shaft 32. The second power component 33 provides rotational power to the second air shaft 32 and drives the upper kraft paper roll 34 to perform an unwinding action.

[0081] Furthermore, in this embodiment, the second power component 33 also adopts a handwheel. The operator rotates the handwheel to rotate the second air shaft 32, thereby realizing the rotation of the second air shaft 32. The rotation of the second air shaft 32 realizes the unwinding action of the upper kraft paper roll 34. Of course, the second power component 33 can also adopt an electric structure, such as a motor, to drive the rotation of the second air shaft 32, thereby realizing the unwinding action of the upper kraft paper.

[0082] The patent CN113927813B, concerning a continuous foaming production method for polyurethane boards, discloses a non-standard equipment for a continuous foaming production line for polyurethane boards. In this non-standard equipment, the unwinding action of the upper kraft paper is designed to occur before the filling process, thereby forming a foaming cavity with an upper surface paper, left and right side papers, and a bottom glass fiber cloth before the filling process. This structure restricts the filling process to only the filling position of the upper surface paper. Therefore, during the filling process, it is necessary to ensure that the filling tool 22 is aligned with the filling position on the foaming cavity. Thus, this part of the workflow usually involves pressing the material and then adjusting the filling tool 22 to fill the material. At this time, the material will stop during the filling process, thereby reducing the working efficiency of the entire production line.

[0083] In this embodiment, the unwinding action of the upper kraft paper is placed after the filling process, ensuring that the foaming cavity is in an open state during the filling process. This expands the filling area of ​​the filling tool and the foaming cavity, so that the material does not need to stop during the actual filling process and the filling work can be completed during the material's movement, thereby improving the working efficiency of the entire production line.

[0084] The shaping conveyor line 4 is used to heat and shape materials.

[0085] The shaping conveyor line includes a frame 41, a bottom track conveyor 42, a side track conveyor 43, a first steam heating system 44, and a pressing roller trolley 45.

[0086] The frame 41 is equipped with a bottom tracked conveyor line 42 for conveying filling materials and a side tracked conveyor line 43 extending in the direction of material movement to cooperate with the bottom tracked conveyor line 42. The two side tracked conveyor lines 43 restrict the two sides of the filling materials. The first steam heating system 44 and the pressing roller trolley 45 are located on the same vertical surface and provide hot air for the filling materials. The pressing roller trolley 45 is installed on the inlet side of the frame 41 and presses down the filling materials under the drive of the power source.

[0087] As a further optimization of the above solution, the aforementioned pressing roller trolley 45 includes a mounting frame 451 mounted on a frame 41. Below the mounting frame 451 are staggered first pressing roller assemblies 452 and second pressing roller assemblies 453. The power source is a third power component 454, which provides power to the first pressing roller assemblies 452 and second pressing roller assemblies 453 and drives them to vertically lift and lower. The first pressing roller assemblies 452 and second pressing roller assemblies 453... Both are connected to racks 455. Driven by gears 456, the two racks 455 move in opposite directions to drive the first pressing roller assembly 452 and the second pressing roller assembly 453 to move in opposite directions. The fourth power unit 457 provides power to gears 456 and drives gears 456 to rotate. By staggering the double pressing roller structure, the pressing effect is maximized. Under the action of gears 456 and racks 455, the width of the double pressing roller structure can be adjusted to ensure rolling of materials of different widths and improve the rolling effect of pressing roller trolley 45.

[0088] Furthermore, in this embodiment, the third power component 454 adopts a sprocket structure. The first roller assembly and the second roller assembly form an integrated lifting structure through the lifting frame. Specifically, the sprocket drive motor drives the sprocket to rotate. At least one sprocket is mounted on the mounting frame 451. A lead screw is threadedly installed in the middle of the sprocket mounted on the mounting frame 451. Two adjacent sprockets on the same horizontal plane are connected by a chain. The chain drive motor drives the sprocket to rotate. Under the action of the chain, the remaining sprockets rotate, thereby driving the lead screw to move vertically. The lead screw is connected to the above-mentioned lifting structure and moves linearly with the lifting structure.

[0089] Drying oven 5 is used to heat and solidify materials.

[0090] The drying room 5 includes a heating space 51 and a conveying device 52 that runs through both ends of the heating space 51. The bottom and both sides of the heating space 51 are provided with a second steam heating system 53, which provides hot air to the bottom and both sides of the heating space 51.

[0091] In this embodiment, the first steam heating system 44 and the second steam heating system 53 have the same structure, both including an explosion-proof centrifugal fan, a radiator, and a duct. The explosion-proof centrifugal fan, radiator, and duct are connected in sequence. The steam inlet and steam outlet are both installed on the radiator. An external steam source is connected to the steam inlet and supplies steam to the radiator. The explosion-proof centrifugal fan provides power to the radiator to push the steam along the radiator to the duct. The function of the radiator is to reduce the inlet temperature of the steam to avoid high-temperature steam damaging the duct inlet. Furthermore, the duct has multiple air outlets arranged in a straight line. After the steam is pushed into the duct, it flows out through the multiple air outlets to achieve the purpose of steam heating.

[0092] Transition line 6 is used to achieve room temperature cooling of materials.

[0093] In this structure, the transition line 6 mainly adopts an open transportation section. For example, the aforementioned conveyor section 111 adopts a crawler conveyor line. The crawler conveyor line is assembled by using two non-standard chains with several irregular aluminum profiles in between. Using aluminum profiles helps to reduce the weight of the system and increase the conveying distance. Both non-standard chains are equipped with sprockets, one of which is a drive wheel 76. A drive wheel 76 drive motor is installed on the drive wheel 76. The drive wheel 76 drive motor drives the drive wheel 76 to rotate. The rotation of the drive wheel 76 drives the non-standard chain to move, thereby realizing the movement of the entire crawler conveyor line.

[0094] Follow-up cutting station 7 is used to realize the follow-up cutting of materials.

[0095] As a further optimization of the above solution, the follow-up cutting station 7 includes a cutting platform 71 and a follow-up base 72. The workpiece to be cut is conveyed to the cutting platform 71 and moves synchronously with the cured material under the drive of the follow-up base 72. One reciprocating motion of the cutting platform 71 completes the cutting and moving action of a cured material.

[0096] As a further optimization of the above solution, the cutting platform 71 includes a cutting saw 73 mounted on the cutting platform 71. The cutting saw 73 has an arc-shaped receiving space 75 for the saw blade 74 to enter. The side of the cutting saw 73 away from the workpiece to be cut is the driving side and the other side is the cutting side. The driving wheel 76 is arranged on the driving side and two driven wheels 77 are arranged on the cutting side. The saw blade 74 passes through the driving wheel 76 and the two driven wheels 77 to form a closed cutting saw 73 structure. The fifth power member 78 is the power source of the driving wheel 76 and drives the driving wheel 76 to rotate so that the saw blade 74 moves around the shape of the cutting saw 73 structure.

[0097] Furthermore, in this embodiment, the fifth power component 78 is a motor for the drive wheel 76. The drive wheel 76 is driven to rotate by the motor for the drive wheel 76. Under the action of the driven wheel 77, the saw blade 74 moves around the shape of the cutting saw 73 structure to ensure that the saw blade 74 forms a closed saw blade 74 for cutting, thereby ensuring the cutting effect.

[0098] The aforementioned structure enhances the versatility of the cutting process, ensuring the synchronization of cutting while the material is being transported forward, thereby improving the overall production efficiency of the foaming production line and enabling one-time cutting while the material is being transported.

[0099] In summary, the multi-component continuous foaming production line of the present invention achieves foaming production under reasonable unwinding conditions, reduces the difficulty of the separation process, adds heating and shaping and heating and curing structures to the pressing section to improve the finished product effect of polyurethane boards, and adopts a follow-up cutting structure in the cutting section to ensure the cutting action of materials during the conveying process, thereby greatly improving the production efficiency of the foaming production line.

[0100] This embodiment also provides a method for producing multi-component continuous foaming lines, which specifically includes the following steps:

[0101] Step a: The lower layer unwinding is completed by the lower layer kraft paper unwinding mechanism and the glass fiber unwinding mechanism located at the front of the equipment, and then conveyed by the line.

[0102] Specifically, in this embodiment, the lower kraft paper unwinding mechanism and the glass fiber unwinding mechanism constitute the first unwinding mechanism 1.

[0103] In detail, the first unwinding mechanism 1 includes a material feeding platform 11, a kraft paper guide roller 12, a front-end guide assembly 13, and a fiberglass unwinding unit 14. The material feeding platform 11 is provided with a material conveying section 111. The kraft paper guide roller 12, the fiberglass unwinding unit 14, and the fiberglass pressing assembly 15 are arranged sequentially along the conveying path of the conveying section 111, wherein:

[0104] The kraft paper guide roller 12 includes a first unwinding seat 121, a first air shaft 122, a first power component 123, and a lower kraft paper roll. The first unwinding seat 121 is equipped with a rotatable first air shaft 122, and the lower kraft paper roll is wound around the first air shaft 122. The first power component 123 provides rotational power to the first air shaft 122 and drives the lower kraft paper roll to perform an unwinding action.

[0105] The number of fiberglass unwinding units 14 is at least three and they are installed on the path of the lower kraft paper and some or all of the fiberglass unwinding units 14 are laid on the lower kraft paper.

[0106] In detail, in this embodiment, the lower kraft paper and glass fiber structure form an open-top filling cavity for the filling tool to fill the cavity.

[0107] Step b: After the lower layer is unwound, it is conveyed by the production line to position 2 of the fabric feeding machine, and the filling tool 22 completes the filling.

[0108] Specifically, in this embodiment, the fabric feeding machine 2 includes a fabric feeding platform 21 and an injection tool 22. The extruded glass fiber and the lower kraft paper form the material to be injected and are transported to the fabric feeding platform 21. The injection end of the injection tool 22 is located above the material to be injected and is filled with the material under the action of the power source.

[0109] Step c: The upper kraft paper unwinding mechanism covers the filled product with kraft paper.

[0110] It should be noted that, in this embodiment, the upper kraft paper unwinding mechanism is the second unwinding mechanism 3. The second unwinding mechanism 3 includes a second unwinding seat 31, a second air shaft 32, a second power component 33, and an upper kraft paper roll 34. The second unwinding seat 31 is equipped with a rotatable second air shaft 32, and the upper kraft paper roll 34 is wound around the second air shaft 32. The second power component 33 provides rotational power to the second air shaft 32 and drives the upper kraft paper roll 34 to perform an unwinding action.

[0111] Step d: Enter the shaping conveyor line 4, where the heating device at the bottom of the track conveyor line heats and shapes the material.

[0112] The shaping conveyor line includes a frame 41, a bottom track conveyor 42, a side track conveyor 43, and a first steam heating system 44. The frame 41 is equipped with the bottom track conveyor 42 for conveying filling materials and the side track conveyor 43 extending in the direction of material movement to cooperate with the bottom track conveyor 42. The two side track conveyors 43 restrict the two sides of the filling material. The first steam heating system 44 and the pressing roller trolley 45 are located on the same vertical surface and provide hot air for the filling material.

[0113] Furthermore, the shaping conveyor line in step d may also include a pressing roller trolley 45, which is installed on the inlet side of the frame 41 and presses down to fill the material under the drive of the power source.

[0114] In detail, in this embodiment, the aforementioned pressing roller trolley 45 includes a mounting frame 451 mounted on a frame 41. Below the mounting frame 451 are staggered first pressing roller assemblies 452 and second pressing roller assemblies 453. The power source is a third power component 454, which provides power to the first pressing roller assemblies 452 and second pressing roller assemblies 453 and drives them to vertically lift and lower. The first pressing roller assemblies 452 and second pressing roller assemblies 453... Both are connected to racks 455. Driven by gears 456, the two racks 455 move towards or away from each other to drive the first pressing roller assembly 452 and the second pressing roller assembly 453 to move towards or away from each other. The fourth power unit 457 provides power to gears 456 and drives gears 456 to rotate. By staggering the double pressing roller structure, the pressing effect is maximized. Under the action of gears 456 and racks 455, the width of the double pressing roller structure can be adjusted to ensure rolling of materials of different widths and improve the rolling effect of pressing roller trolley 45.

[0115] Step e: Enter the drying chamber 5. The entire line moves synchronously through the internal conveyor belt and the front part, while the curing is completed by steam heating.

[0116] The drying room 5 includes a heating space 51 and a conveying device 52 that runs through both ends of the heating space 51. The bottom and both sides of the heating space 51 are provided with a second steam heating system 53, which provides hot air to the bottom and both sides of the heating space 51.

[0117] Step f: After exiting the drying chamber 5, the product arrives at the transition conveyor line, where room temperature is used to cool the product.

[0118] In this structure, the transition line 6 mainly adopts an open-type transportation section. For example, the aforementioned conveyor section 111 adopts a crawler conveyor line. This crawler conveyor line is assembled by using two non-standard chains with several irregularly shaped aluminum profiles in between. Using aluminum profiles helps to reduce the weight of the system and increase the conveying distance. Both of the aforementioned non-standard chains are equipped with sprockets, one of which is a drive wheel 76. A drive wheel 76 drive motor is installed on the drive wheel 76. The drive wheel 76 is driven to rotate by the drive wheel 76 drive motor. The rotation of the drive wheel 76 drives the non-standard chain to move, thereby realizing the movement of the entire crawler conveyor line. Through the open structure, the heated and shaped material is exposed to the outside air, and the shaping effect is enhanced by cooling at room temperature.

[0119] Step g: After cooling, the device enters the follow-up cutting station 7. The follow-up cutting station 7 completes the cutting work by pressing, cutting, releasing, and resetting. This process is repeated to achieve the follow-up cutting function.

[0120] The follow-up cutting station 7 includes a cutting platform 71 and a follow-up base 72. The workpiece to be cut is conveyed to the cutting platform 71 and moves synchronously with the cured material under the drive of the follow-up base 72. One reciprocating motion of the cutting platform 71 completes the cutting and moving action of a cured material.

[0121] As a further optimization of the above solution, the cutting platform 71 includes a cutting saw 73 mounted on the cutting platform 71. The cutting saw 73 has an arc-shaped receiving space 75 for the saw blade 74 to enter. The side of the cutting saw 73 away from the workpiece to be cut is the driving side and the other side is the cutting side. The driving wheel 76 is arranged on the driving side and two driven wheels 77 are arranged on the cutting side. The saw blade 74 passes through the driving wheel 76 and the two driven wheels 77 to form a closed cutting saw 73 structure. The fifth power member 78 is the power source of the driving wheel 76 and drives the driving wheel 76 to rotate so that the saw blade 74 moves around the shape of the cutting saw 73 structure.

[0126] The number of fiberglass unwinding units 14 is at least three and they are installed on the path of the lower kraft paper and some or all of the fiberglass unwinding units 14 are laid on the lower kraft paper.

[0127] The fiberglass pressing assembly 15 includes a fixed frame 151 designed at the tail end of the feeding platform 11 and a pressing block 152 installed on the fixed frame 151. The pressing block 152 squeezes the fiberglass and the lower kraft paper. Through the squeezing operation of the fiberglass pressing assembly 15, the bonding effect between the fiberglass and the lower kraft paper is strengthened.

In this embodiment, the second unwinding mechanism 3 includes a second unwinding seat 31, a second air shaft 32, a second power component 33, and an upper kraft paper roll 34. The second unwinding seat 31 is equipped with a rotatable second air shaft 32, and the upper kraft paper roll 34 is wound around the second air shaft 32. The second power component 33 provides rotational power to the second air shaft 32 and drives the upper kraft paper roll 34 to perform an unwinding action.

[0132] Heating and shaping is used to heat and shape materials to be shaped while in a conveying state, and to obtain the shaped material.

[0133] The heating and shaping process is mainly achieved through the shaping conveyor line 4, which includes a frame 41, a bottom track conveyor line 42, a side track conveyor line 43, a first steam heating system 44, and a pressing roller trolley 45. Specifically, the frame 41 is equipped with a bottom track conveyor line 42 for conveying filling materials and a side track conveyor line 43 extending in the direction of material movement to cooperate with the bottom track conveyor line 42. The two side track conveyor lines 43 restrict the two sides of the filling materials. The first steam heating system 44 and the pressing roller trolley 45 are located on the same vertical surface and provide hot air for the filling materials. The pressing roller trolley 45 is installed on the inlet side of the frame 41 and presses down the filling materials under the drive of the power source.

[0134] As a further optimization of the above solution, the aforementioned pressing roller trolley 45 includes a mounting frame 451 mounted on a frame 41. Below the mounting frame 451 are staggered first pressing roller assemblies 452 and second pressing roller assemblies 453. The power source is a third power component 454, which provides power to the first pressing roller assemblies 452 and second pressing roller assemblies 453 and drives them to vertically lift and lower. The first pressing roller assemblies 452 and second pressing roller assemblies 453... Both are connected to racks 455. Driven by gears 456, the two racks 455 move in opposite directions to drive the first pressing roller assembly 452 and the second pressing roller assembly 453 to move in opposite directions. The fourth power unit 457 provides power to gears 456 and drives gears 456 to rotate. By staggering the double pressing roller structure, the pressing effect is maximized. Under the action of gears 456 and racks 455, the width of the double pressing roller structure can be adjusted to ensure rolling of materials of different widths and improve the rolling effect of pressing roller trolley 45.

[0135] Heating curing is used to heat and cure materials after they have been shaped, and to obtain cured materials.

[0136] The heating and curing process is mainly achieved through the drying room 5, which includes a heating space 51 and a conveying device 52 that runs through both ends of the heating space 51. The bottom and both sides of the heating space 51 are equipped with a second steam heating system 53, which provides hot air to the bottom and both sides of the heating space 51.

[0137] Room temperature cooling is used to cool cured materials at room temperature and obtain cooled materials.

[0138] The room temperature cooling process is mainly achieved through the transition line 6. In this structure, the transition line 6 mainly adopts an open transport section. For example, the aforementioned transport section 111 adopts a crawler conveyor line. The crawler conveyor line is assembled by using two non-standard chains with several irregularly shaped aluminum profiles in between. Using aluminum profiles helps to reduce the weight of the system and increase the transport distance. Both non-standard chains are equipped with sprockets, one of which is a drive wheel 76. A drive wheel 76 drive motor is installed on the drive wheel 76. The drive wheel 76 drive motor drives the drive wheel 76 to rotate. The rotation of the drive wheel 76 drives the non-standard chain to move, thereby realizing the movement of the entire crawler conveyor line. Through the open structure, the heated and shaped material is exposed to the outside air, and the sculpting effect is enhanced by room temperature cooling.

[0139] Follow-up cutting is used to complete the cutting work while the material moves after follow-up cooling, and to obtain the cut material.

[0140] The follow-up cutting process is implemented through the follow-up cutting station 7. Specifically, the follow-up cutting station 7 includes a cutting platform 71 and a follow-up base 72. The workpiece to be cut is conveyed to the cutting platform 71 and moves synchronously with the cured material under the drive of the follow-up base 72. One reciprocating motion of the cutting platform 71 completes the cutting and moving action of a cured material.

[0141] As a further optimization of the above solution, the cutting platform 71 includes a cutting saw 73 mounted on the cutting platform 71. The cutting saw 73 has an arc-shaped receiving space 75 for the saw blade 74 to enter. The side of the cutting saw 73 away from the workpiece to be cut is the driving side and the other side is the cutting side. The driving wheel 76 is arranged on the driving side and two driven wheels 77 are arranged on the cutting side. The saw blade 74 passes through the driving wheel 76 and the two driven wheels 77 to form a closed cutting saw 73 structure. The fifth power member 78 is the power source of the driving wheel 76 and drives the driving wheel 76 to rotate so that the saw blade 74 moves around the shape of the cutting saw 73 structure.

[0142] In summary, the multi-component continuous foaming production process in this embodiment fills the gap in the curing process in existing multi-component continuous foaming production processes, strengthens the continuity of the filling and cutting processes, achieves foaming production under reasonable unwinding conditions, reduces the difficulty of the separation process, adds heating and shaping and heating and curing structures to the pressing section to improve the finished product effect of polyurethane boards, and adopts a follow-up cutting structure in the cutting section to ensure the cutting action of materials during the conveying process, which greatly improves the production efficiency of the foaming production line.
