Description

Technical Field

[0001] This invention relates to the field of PVC foam board processing technology, and in particular to a PVC foam board device and its usage method based on a cutting and embossing process. Background Technology

[0002] PVC foam board is a fire-resistant material made of polyvinyl chloride. It is mainly used as lightweight interior partition material, sound insulation material for audiovisual spaces, fireproof material, packaging material for refrigeration and air conditioning projects, roof insulation material, and furniture interior material. It possesses properties such as moisture resistance, weather resistance, impact resistance, heat insulation, acid and alkali corrosion resistance, and flame retardancy.

[0003] Currently, in the production process of PVC foam boards, in order to improve the product's appearance and texture while giving it more functionality and practical value, surface embossing is required. Most existing PVC foam board surface embossing methods use roller pressing. For example, a PVC vacuum forming sheet pressing device disclosed in Chinese Patent Application Publication No. CN214729992U, while using a locking mechanism to fix one end of the PVC vacuum forming sheet, secures the sheet by pulling down a fixing ring with an air tube and connecting block. This facilitates the placement of the PVC vacuum forming sheet into the pressing area without the need for sequentially tightening bolts, improving efficiency and saving time and labor. However, in actual production, due to different customer needs, the embossed patterns on the surface of PVC foam boards are also different. This requires the use of different embossing rollers for embossing processing. Traditional equipment mostly uses single-roller embossing, and changing embossing rollers for different patterns each time is very time-consuming, cumbersome, and affects efficiency. Secondly, if the freshly produced PVC foam boards are preheated directly on the production line with a hot air blower, the high power of the hot air blower will increase energy consumption significantly, and heat control will also be problematic. Overheating can easily cause the preheated surface of the foam board to turn yellow. Therefore, to address the above-mentioned problems, this application provides a PVC foam board device and its preparation method based on cutting and embossing process to meet the needs. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a PVC foam board device and its usage method based on a cutting and embossing process. This solves the problems of existing PVC foam boards requiring frequent disassembly and replacement of pressure rollers when catering to different customers and embossing needs. This is not only time-consuming and labor-intensive but also affects efficiency. Furthermore, the energy consumption increases when the hot air blower performs independent preheating, and the heat is difficult to control, with excessive heat causing the preheated surface to yellow.

[0013] Preferably, the rotating module includes a rotating motor, a central shaft, wear-resistant bearings, an inner liner tightening ring, and reinforcing bolts. The rotating motor has a central shaft at its front end, wear-resistant bearings are provided on the left and right sides of the outer end of the central shaft, an inner liner tightening ring is provided on the front side of the wear-resistant bearings, and reinforcing bolts are distributed in a ring around the outer end of the inner liner tightening ring.

[0014] Preferably, the adjustment module includes an outer ring block, an inner ring block, a reinforcing hole, an annular hole, and meshing teeth. The inner ring block is provided on the inner side of the outer ring block, and a reinforcing hole is provided in the middle of the inner side of the inner ring block. Annular holes are distributed on the outer side of the front end of the outer ring block, and meshing teeth are provided at the contact end between the outer ring block and the inner ring block.

[0015] Preferably, the embossing module includes an embossing roller, a sleeve, an embossing shaft, guide wheels, and reinforcing rings. The embossing roller has sleeves on the left and right sides of its outer end, an embossing shaft on its inner side, guide wheels on the left and right sides of the outer end of the embossing shaft, and reinforcing rings on the front and rear sides of the guide wheels.

[0016] Preferably, the sliding module includes a sliding plate, a vertical block, a drive motor, a drive wheel, and a positioning pin. The vertical block is provided on the front side of the upper end of the sliding plate, the drive motor is provided on the inner side of the middle of the vertical block, the drive wheel is provided at the front end of the drive motor, and the positioning pin is provided in the middle of the upper end of the vertical block.

[0017] A PVC foam board device based on cutting and embossing technology and its usage method include the following steps:

[0018] Step 1: First, the servo motors symmetrically distributed at the front and rear ends of the front conveyor and docking conveyor are turned on, which drives the screws set on the inner side of the upper end of the front conveyor and docking conveyor to start rotating, and moves the displacement lifting modules located in different areas at the front and rear to the appropriate position and stops according to the embossing requirements.

[0019] Step 2: By turning on the rotary motor in the rotary module, the adjustment module starts to rotate. Due to the meshing teeth set at the contact ends of the outer and inner ring blocks of the adjustment module, the inner ring block will drive the outer ring block to rotate during the rotation, causing the embossing rollers with different patterns installed on the outer ring front side of the outer ring block to rotate. Then, according to the embossing requirements, the embossing roller with the pattern to be used is rotated to the lower position and then stopped.

[0020] Step 3: Open the sliding door in the symmetrically distributed displacement lifting module, and push the left and right sliding modules installed on the inner side to move to the opposite side. When the transmission wheel in the left and right sliding module contacts the guide wheel installed at the left and right ends of the embossing roller, the two form an engagement and holding angle. Then, connect to the external power supply through the line connector installed at the right end of the embossing roller to supply power to the built-in heating rod of the embossing roller, thereby heating the embossing roller.

[0021] Step 4: While heating the embossing roller, power is supplied to the winding motor of the winding heat insulation curtain, and the winding heat insulation curtain is moved downward along the slot block in the displacement lifting module. The heat insulation curtain is blocked on both sides of the frame structure formed by the displacement lifting module, the installation module and the arc cover, so that the heat generated by the heating of the embossing roller is blocked and does not easily leak out.

[0022] Step 5: After the internal heating of the frame structure formed by the displacement lifting module, the installation module and the arc cover is completed, since the arc cover and the preheating module are connected by the conveying pipeline, the excess hot air can be introduced into the preheating module and absorbed and stored by the recovery heater inside the preheating box. The stored heat can heat the air inside the preheating box. When the PVC foam board passes below, the hot air will preheat the embossed surface on the top of the PVC foam board.

[0023] Step Six: After the preheated PVC foam board enters the frame structure formed by the displacement lifting module, the installation module and the arc cover, the transmission motor drives the transmission wheel to rotate. The transmission wheel and the guide wheel mesh with each other, thereby driving the embossing roller to emboss the PVC foam board.

[0024] Compared with the prior art, the present invention has at least the following beneficial effects:

[0025] In the above solution, multiple embossing modules of different shapes can be installed on the outside through the adjustment module. When adjustment is needed, simply turn on the rotary motor in the rotary module to rotate the adjustment module, moving the desired embossing module to the bottom so that it contacts the transmission wheel driven by the transmission motor in the sliding module, and then it can start rotating and embossing. Compared with traditional embossing, which requires disassembling and replacing the embossing structure for different patterns, only the position of the sliding module needs to be adjusted before each replacement, which is faster and saves time and effort. It is especially efficient when embossing different batches and patterns of PVC foam boards.

[0026] The curved cover, along with the displacement lifting module and the installation module, forms a frame structure with openings on only two sides. Combined with symmetrically installed retractable heat insulation curtains, the embossing process takes place in a relatively enclosed environment, preventing heat loss from the embossing module. The curved cover is then connected to the preheating module via pipes. Excess heat flows into the preheating module through the delivery pipes, heating the medium pipe in the recovery heater. The hot airflow inside the preheating chamber then exits through the lower opening, preheating the PVC foam board embossing surface. This process recovers and reuses excess heat from the embossing module. Simultaneously, the preheating of the PVC foam board embossing surface via heat absorption and reheating through the medium pipes makes heat control easier and safer.

[0027] By setting up a front conveyor and a docking conveyor, two sets of embossing structures can be installed on the upper end of the two. When encountering more complex embossing shapes and requirements, a staged embossing process can be formed, relying on the two embossing processes to achieve the final forming effect. At the same time, by setting up a servo motor and screw, the position of the two sets of embossing structures can also be adjusted to better adapt to different embossing requirements.

[0028] In summary, this invention has the advantages of allowing for quick replacement of the embossing structure to meet different embossing requirements, while also improving the preheating method of the foam board to make the generated temperature more controllable and reduce energy consumption.

However, this is only for illustrative purposes and is not intended to limit the present invention to these specific structures, devices, and environments. Those skilled in the art can adjust or modify these devices and environments according to specific needs, and such adjustments or modifications are still included within the scope of the appended claims. Detailed Implementation

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] The PVC foam board device and its preparation method based on the cutting and embossing process provided by the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should also be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art can use other alternative methods to implement some known technologies; moreover, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0047] Implement column 1, such as Figures 1 to 13 As shown, an embodiment of the present invention provides a PVC foam board device based on a cutting and embossing process, including a front conveyor 1, a docking conveyor 2 at the rear end of the front conveyor 1, a displacement lifting module 3 at the upper end of the front conveyor 1, an installation module 4 at the upper end of the displacement lifting module 3, an arc cover 5 at the middle of the upper end of the installation module 4, a preheating module 6 at the front side of the displacement lifting module 3, a rotating module 7 at the left side of the upper end of the installation module 4, adjustment modules 8 on the left and right sides of the outer end of the rotating module 7, an embossing module 9 at the middle of the adjustment module 8, a rewinding heat insulation curtain 10 at the front and rear sides of the upper end of the installation module 4, a sliding module 11 at the lower middle of the inner side of the displacement lifting module 3, a servo motor 12 at the upper front end of the front conveyor 1, and a screw 13 at the inner side of the upper end of the front conveyor 1.

[0048] The rear end of the front conveyor 1 is spliced ​​with the front end of the docking conveyor 2 in a straight line. Both have transverse slots on their upper left and right sides. The displacement lifting modules 3 are symmetrically distributed, and the lower ends of the symmetrically distributed displacement lifting modules 3 extend into the transverse slots on the upper ends of the front conveyor 1 and the docking conveyor 2, and are threaded through by screws 13. The upper end of the displacement lifting module 3 is reinforced with the contact end of the mounting module 4 by bolts to form an integrated structure. The contact end of the arc cover 5 with the mounting module 4 is reinforced with screws. Furthermore, the lower middle parts of the left and right sides of the arc cover 5 are closely fitted with the protruding structure at the upper end of the mounting module 4. The preheating module 6 is connected to the arc cover 5 through a conveying pipeline. The preheating module 6 is connected and fixed together with the displacement lifting module 3. The lower middle part of the preheating module 6 extends into the transverse slot opened at the upper end of the front conveyor 1 and the docking conveyor 2, and is threaded through by the screw 13. The front end of the rotating module 7 passes through the protruding structures on the left and right sides of the upper end of the mounting module 4. The adjusting modules 8 are symmetrically distributed on the left and right sides. The adjusting modules 8 and The rotating modules 7 are connected in a socketed installation structure, and the socket contact ends are fixed, making them an integral structure. The embossing modules 9 are arranged in a ring on the inner side of the symmetrically distributed adjusting modules 8, and both ends of the embossing modules 9 penetrate the interior of the symmetrically distributed adjusting modules 8 and extend to the outside. The winding heat insulation curtain 10 is symmetrically distributed front and back. The winding heat insulation curtain 10 is an integral structure composed of curtain fabric, winding roller and winding motor. The mounting module 4 area located directly below the winding heat insulation curtain 10 has a slot. The sliding module 11 is installed... The sliding module 11 is installed in the lower middle part of the inner side of the displacement lifting module 3. Two partitions are provided at the left and right ends of the sliding module 11 to separate the internal space of the displacement lifting module 3. The servo motor 12 is installed on both sides above the front end of the front conveyor 1 and on both sides above the rear end of the docking conveyor 2. The transmission end of the servo motor 12 and the screw 13 are integrated. The screw 13 is installed in the transverse slots opened at the upper end of the front conveyor 1 and the docking conveyor 2. Bearings are sleeved and installed at the front and rear contact walls of the two.

[0049] The adjustment module 8 allows multiple embossing modules 9 of different shapes to be installed on its outer side. When adjustment is needed, simply turn on the rotary motor 701 in the rotary module 7 to rotate the adjustment module 8, moving the desired embossing module 9 to the bottom so that it contacts the transmission wheel 114 driven by the transmission motor 113 in the sliding module 11. This allows it to rotate and begin the embossing process. Compared to traditional embossing, which requires disassembling and replacing the embossing structure for different patterns, this method only requires adjusting the position of the sliding module 11 before each replacement. This is faster, more time-saving, and less labor-intensive, especially when embossing different batches and patterns of PVC foam boards.

[0050] The arc-shaped cover 5, together with the displacement lifting module 3 and the installation module 4, forms a frame structure with openings on both sides. Combined with the symmetrically installed retractable heat insulation curtain 10, the embossing process is carried out in a relatively enclosed environment, blocking the heat generated in the embossing module 9 and preventing heat leakage. Then, the arc-shaped cover 5 is connected to the preheating module 6 via a pipe. Excess heat enters the preheating module 6 through the conveying pipeline, heating the medium pipe 605 in the recovery heater 603. The hot airflow inside the preheating box 601 then exits from the lower opening, preheating the PVC foam board embossing surface. This achieves the recovery and reuse of excess heat in the embossing module 9. Simultaneously, the preheating of the PVC foam board embossing surface through the heat absorption and reheating via the medium pipe 605 makes heat control easier and safer.

[0051] Implement column 2, such as Figures 2 to 4 As shown, in this embodiment, the displacement lifting module 3 includes a displacement seat 301, a telescopic column 302, a buffer pad 303, a slot block 304, a slider 305, and a sliding door 306. The telescopic column 302 is provided on the left and right sides of the upper end of the displacement seat 301, the buffer pad 303 is provided in the middle of the upper end of the displacement seat 301, the slot block 304 is provided on the left and right sides of the front end of the displacement seat 301, the slider 305 is provided in the middle of the lower end of the displacement seat 301, and the sliding door 306 is provided on the inner side of the rear end of the displacement seat 301. The installation module 4 includes a rectangular frame 401, a protrusion 402, a positioning hole 403, and a vertical plate 404. The protrusion 402 is provided on the left and right sides of the upper end of the rectangular frame 401, the positioning hole 403 is provided on the front and rear sides of the protrusion 402, and the vertical plate 404 is symmetrically distributed on the front and rear sides of the upper end of the rectangular frame 401.

[0052] The displacement seat 301 has a hollow internal structure. The lower end of the telescopic column 302 extends into the interior of the displacement seat 301. The telescopic column 302 is hydraulically driven for lifting, which is a well-known technology and will not be described in detail here. The buffer pad 303 is installed in the middle area of ​​the lower ends of the two telescopic columns 302. The buffer pad 303 is made of rubber and is used to reduce the force when the rectangular frame 401 contacts the displacement seat 301, thus providing protection. The slot block 304 and the slider 305 are integrated with the displacement seat 301. The structure includes four symmetrically distributed slot blocks 304, two on each side. The slots on opposite sides of the slot blocks 304 are used to guide the rewinding of the heat insulation curtain 10. A through hole is provided in the middle of the slider 305, and the diameter of the through hole is compatible with the screw 13. The sliding door 306 consists of two parts, left and right, which are staggered front and back. The rectangular frame 401 and the protrusion 402 are integrated. The positioning holes 403 are symmetrically distributed. There are four symmetrically distributed upright plates 404, two on each side, front and back, for the installation of the rewinding heat insulation curtain 10.

[0053] The displacement seat 301 is divided into three areas (left, right, and center) by two partitions in the middle. A sliding module 11 is installed in the center. The contact end of the sliding module 11 with the two partitions is a sliding installation structure, which facilitates the front and rear position of the sliding module 11 so that the sliding module 11 can mesh with the guide wheel 904 in the embossing module 9. The left and right areas inside the displacement seat 301 are used to install the telescopic column 302 and the hydraulic structure. When it is necessary to maintain the embossing module 9 and clean up the garbage below, the telescopic column 302 can be extended to raise the rectangular frame 401.

[0054] Implement column 3, such as Figure 1 and Figure 5 As shown, in this embodiment, the arc cover 5 includes a cover plate 501, a protruding plate 502, a fixing plate 503, and a heat recovery port 504. The lower end of the cover plate 501 is provided with protruding plates 502 on the left and right sides, and the front and rear sides of the protruding plates 502 are provided with fixing plates 503 above them. The upper end of the cover plate 501 is provided with heat recovery ports 504 on the left and right sides.

[0055] A semi-circular cavity is provided on the inner side of the lower end of the cover plate 501. The cover plate 501, the protruding plate 502 and the fixing plate 503 are integrated into one structure. There are two heat recovery ports 504 symmetrically distributed on the left and right sides.

[0056] The heat recovery port 504 can discharge the residual heat in the semi-circular cavity inside the cover plate 501. The heat recovery port 504 and the preheating module 6 are connected by a conveying pipeline for heat recovery and reuse. Compared with the traditional equipment that uses direct heating for preheating before embossing, this reduces energy consumption and saves costs.

[0057] Implement column 4, such as Figure 1 and Figure 10 As shown, in this embodiment, the preheating module 6 includes a preheating box 601, a connecting rod 602, a recovery heater 603, a sealing plate 604, and a medium pipe 605. The connecting rod 602 is provided on the front side of the outer end of the preheating box 601, the recovery heater 603 is provided inside the preheating box 601, the sealing plate 604 is provided on the upper end of the preheating box 601, and the medium pipes 605 are arranged inside the recovery heater 603.

[0058] A horizontal exhaust port is provided at the lower end of the preheating box 601. The preheating box 601 has two cavities, an upper and a lower one, with a through groove in the middle of the two cavities to connect them. A recovery heater 603 is installed in the upper cavity, and a fan is installed in the lower cavity. The sealing plate 604 is reinforced to the upper end of the preheating box 601 with screws. A medium pipe 605 passes through the interior of the recovery heater 603, and heat transfer oil is injected into the medium pipe 605.

[0059] With the recovery heater 603, when heat enters the preheating box 601 through the two openings at the top of the sealing plate 604, the heat is absorbed by the surrounding medium pipes 605 in the recovery heater 603. Then, the heat is conducted through the medium pipes 605 to the bottom of the recovery heater 603, heating the air inside the preheating box 601. The hot air is then drawn out by a fan installed in the cavity at the bottom of the preheating box 601 and discharged from the horizontal exhaust port at the bottom of the preheating box 601, preheating the embossed surface of the PVC foam board. By recovering and reusing the heat, energy consumption is reduced, costs are saved, and it is more environmentally friendly.

[0060] like Figure 2 and Figure 6 As shown, in this embodiment, the rotating module 7 includes a rotating motor 701, a central shaft 702, an anti-wear bearing 703, an inner liner tightening ring 704, and reinforcing bolts 705. The rotating motor 701 has a central shaft 702 at its front end. The left and right sides of the outer end of the central shaft 702 are provided with anti-wear bearings 703. The front side of the anti-wear bearing 703 is provided with an inner liner tightening ring 704. The outer end of the inner liner tightening ring 704 is circumferentially distributed with reinforcing bolts 705.

[0061] The drive end of the rotary motor 701 is spliced ​​with the central shaft 702 to form an integrated structure. The wear-resistant bearings 703 are symmetrically distributed to reduce wear on the contact end with the mounting module 4. The inner liner tightening rings 704 are symmetrically distributed, and there are four symmetrically distributed reinforcing bolts 705.

[0062] The inner lining tightening ring 704 can tighten and reinforce the inner ring block 802 installed on the central shaft 702, ensuring the stability of the installation structure. Then, when the rotating motor 701 drives the central shaft 702 to rotate, the inner ring block 802 will also rotate along with it, providing rotational power for the embossing module 9 to change different patterns.

[0063] Implement column 5, such as Figure 2 and Figure 7 As shown, in this embodiment, the adjustment module 8 includes an outer ring block 801, an inner ring block 802, a reinforcing hole 803, an annular hole 804, and meshing teeth 805. The inner ring block 802 is provided on the inner side of the outer ring block 801. The reinforcing hole 803 is provided in the middle of the inner side of the inner ring block 802. The annular holes 804 are distributed on the outer side of the front end of the outer ring block 801. The contact end between the outer ring block 801 and the inner ring block 802 is provided with meshing teeth 805.

[0064] The adjustment module 8 has two sets of symmetrically distributed left and right. The outer ring block 801 and the inner ring block 802 are meshed and driven by the meshing teeth 805 set at the contact end. The meshing teeth 805 are composed of the inner tooth groove distributed on the inner side of the outer ring block 801 and the outer tooth distributed on the outer end of the inner ring block 802. The diameter of the reinforcing hole 803 is adapted to the diameter of the central shaft 702 in the rotating module 7. There are eight annular holes 804 distributed in a ring.

[0065] Through the annular hole 804, eight sets of embossing modules 9 with different embossing shapes can be installed on the inner side. When different embossing shapes are needed, the rotating module 7 only needs to drive the inner ring block 802 to rotate. Then, the meshing teeth 805 set at the contact end between the inner ring block 802 and the outer ring block 801 will transmit power, which will drive the outer ring block 801 to start rotating. When the outer ring block 801 rotates, it will also drive the eight sets of embossing modules 9 with different embossing shapes to rotate. When the required set of embossing modules 9 is displaced to the vertical angle below the outer ring block 801, it stops.

[0066] Implement column 6, such as Figure 2 and Figure 8 As shown, in this embodiment, the embossing module 9 includes an embossing roller 901, a sleeve 902, an embossing shaft 903, a guide wheel 904, and a reinforcing ring 905. The sleeve 902 is provided on the left and right sides of the outer end of the embossing roller 901, and the embossing shaft 903 is provided on the inner side of the embossing roller 901. The guide wheel 904 is sleeved and installed on the left and right sides of the outer end of the embossing shaft 903, and the reinforcing ring 905 is provided on the front and rear sides of the guide wheel 904.

[0067] Different embossing molds can be installed on the outer end of the embossing roller 901. The embossing roller 901 and the embossing shaft 903 are integrated into one structure, and both have a hollow structure inside. An electric heating rod is installed inside the hollow structure. The electric heating rod heating the embossing roller 901 is a known technology, so it will not be described in detail in this article. There are two symmetrically distributed sleeves 902, guide rollers 904 and reinforcing rings 905. The front end diameter of the sleeve 902 is compatible with the inner diameter of the annular hole 804.

[0068] The integrated structure consisting of embossing roller 901 and embossing shaft 903 is installed inside the outer ring block 801 in the adjustment module 8 through the sleeve 902. At the same time, when the integrated structure consisting of embossing roller 901 and embossing shaft 903 is driven by the meshing of guide wheel 904 and transmission wheel 114, the sleeve 902 can also ensure the normal rotation of the integrated structure consisting of embossing roller 901 and embossing shaft 903 and reduce wear.

[0069] Implement column 7, such as Figures 3 to 9As shown, in this embodiment, the sliding module 11 includes a sliding plate 111, a vertical block 112, a drive motor 113, a drive wheel 114, and a positioning pin 115. The vertical block 112 is provided on the front side of the upper end of the sliding plate 111, the drive motor 113 is provided on the inner side of the middle part of the vertical block 112, the drive wheel 114 is provided at the front end of the drive motor 113, and the positioning pin 115 is provided in the middle of the upper end of the vertical block 112.

[0070] The sliding plate 111 has horizontal bars on the left and right sides of its outer end to facilitate its sliding motion. The upper part of the sliding plate 111 has a tightening hole at the middle, and a hand grip groove is provided on the rear side of the tightening hole. The sliding plate 111 and the vertical block 112 are integrated. The vertical block 112 has a round hole in the middle, and the horizontal diameter of the round hole is compatible with the horizontal diameter of the drive motor 113. The drive wheel 114 and the drive end of the drive motor 113 are integrated. The lower end of the positioning pin 115 passes through the upper end of the vertical block 112 and extends to the inner side of the drive motor 113.

[0071] The sliding plate 111, with its horizontal bar at the outer end and a hand gripping groove on the rear side at the top, allows for manual adjustment of its position on the inner side of the lower end of the displacement lifting module 3. When it needs to contact the embossing module 9, the sliding plate 111 is pushed forward to engage the front drive wheel 114 with the guide wheel 904 in the embossing module 9, facilitating the transmission of embossing power. When a different embossing module 9 needs to be replaced, the sliding plate 111 is pulled backward to separate the front drive wheel 114 from the guide wheel 904 in the embossing module 9.

[0072] The electrical components mentioned in this article are all connected to an external main controller and mains power, and the main controller can be a conventional known device such as a computer that provides control.

[0073] The PVC foam board device based on the cutting and embossing process and its usage method include the following steps:

[0074] Step 1: First, the servo motors 12, which are symmetrically distributed at the front and rear ends of the front conveyor 1 and the docking conveyor 2, are turned on, which drives the screws 13 set on the inner side of the upper end of the front conveyor 1 and the docking conveyor 2 to start rotating. The displacement lifting modules 3 located in different areas at the front and rear are moved to the appropriate position and stopped according to the embossing requirements.

[0075] Step 2: By turning on the rotary motor 701 in the rotary module 7, the adjustment module 8 is driven to start rotating. Due to the meshing teeth 805 set at the contact end of the outer ring block 801 and the inner ring block 802 of the adjustment module 8, the inner ring block 802 will drive the outer ring block 801 to rotate during the rotation, so that the embossing rollers 901 with different patterns installed on the outer ring of the front end of the outer ring block 801 will rotate. Then, according to the embossing requirements, the embossing roller 901 with the pattern to be used is rotated to the lower position and then stopped.

[0076] Step 3: Open the sliding door 306 in the symmetrically distributed displacement lifting module 3, and push the left and right sliding module 11 installed on the inner side to move to the opposite side. When the transmission wheel 114 in the left and right sliding module 11 contacts the guide wheel 904 installed at the left and right ends of the embossing roller 901, the two form an engagement and holding angle. Then, the line connector installed at the right end of the embossing roller 901 is connected to an external power source to supply power to the built-in heating rod of the embossing roller 901, thereby heating the embossing roller 901.

[0077] Step 4: While heating the embossing roller 901, power is supplied to the winding motor of the winding heat insulation curtain 10, and the winding heat insulation curtain 10 is moved downward along the slot block 304 in the displacement lifting module 3. The two sides of the frame structure formed by the displacement lifting module 3, the mounting module 4 and the arc cover 5 block the heat generated by the heating of the embossing roller 901, preventing it from leaking out.

[0078] Step 5: After the internal heating of the frame structure formed by the displacement lifting module 3, the installation module 4 and the arc cover 5 is completed, since the arc cover 5 and the preheating module 6 are connected by a conveying pipeline, the excess hot air can be introduced into the preheating module 6 and absorbed and stored by the recovery heater 603 inside the preheating box 601. The stored heat can heat the air inside the preheating box 601. When the PVC foam board passes below, the hot air will preheat the embossed surface on the top of the PVC foam board.

[0079] Step 6: After the preheated PVC foam board enters the frame structure formed by the displacement lifting module 3, the installation module 4 and the arc cover 5, the transmission motor 113 drives the transmission wheel 114 to rotate. The transmission wheel 114 meshes with the guide wheel 904, thereby driving the embossing roller 901 to emboss the passing PVC foam board.

[0080] The working principle of the technical solution provided by this invention is as follows: Multiple embossing modules 9 of different shapes can be installed on the outside of the adjustment module 8. When adjustment is needed, simply turn on the rotary motor 701 in the rotary module 7 to rotate the adjustment module 8, moving the desired embossing module 9 to the bottom, where it contacts the transmission wheel 114 driven by the transmission motor 113 in the sliding module 11, thus initiating the embossing process. Compared to traditional embossing methods that require disassembly and replacement of the embossing structure for different patterns, only the position of the sliding module 11 needs to be adjusted before each replacement, making it faster, more time-saving, and labor-saving. This is especially efficient when embossing different batches and patterns of PVC foam boards. Secondly, the set arc cover... 5. Together with the displacement lifting module 3 and the installation module 4, it forms a frame structure with openings on both sides. With the symmetrically installed retractable heat insulation curtain 10, the embossing work is carried out in a relatively closed environment, blocking the heat generated in the embossing module 9 and preventing heat from escaping. Then, the arc cover 5 is connected to the preheating module 6 through the pipeline. Excess heat will enter the preheating module 6 through the conveying pipeline, heating the medium pipe 605 in the recovery heater 603. Then, the hot air flow inside the preheating box 601 is discharged from the lower opening, preheating the PVC foam board embossing surface. This realizes the recovery and reuse of excess heat in the embossing module 9. At the same time, the PVC foam board embossing surface is preheated by absorbing heat through the medium pipe 605. The heat is easier to control and safer.

Step 4: While heating the embossing roller (901), power is supplied to the winding motor of the winding heat insulation curtain (10) to move the winding heat insulation curtain (10) downward along the slot block (304) in the displacement lifting module (3). The two sides of the frame structure formed by the displacement lifting module (3), the installation module (4) and the arc cover (5) are blocked to prevent the heat generated by the heating of the embossing roller (901) from leaking out. Step 5: After the internal heating of the frame structure formed by the displacement lifting module (3), the installation module (4) and the arc cover (5) is completed, since the arc cover (5) and the preheating module (6) are connected by the conveying pipeline, the excess hot air can be introduced into the preheating module (6) and absorbed and stored by the recovery heater (603) inside the preheating box (601). The stored heat can heat the air inside the preheating box (601). When the PVC foam board passes below, the hot air will preheat the embossed surface above the PVC foam board. Step 6: After the preheated PVC foam board enters the frame structure formed by the displacement lifting module (3), the installation module (4) and the arc cover (5), the transmission motor (113) drives the transmission wheel (114) to rotate. The transmission wheel (114) meshes with the guide wheel (904), thereby driving the embossing roller (901) to emboss the PVC foam board.
