[0002] In the current building and decoration materials market, polyvinyl chloride wallboard, namely PVC (Polyvinyl Chloride) wallboard, is widely used in interior wall decoration due to its good waterproof performance, durability and easy cleaning. The existing PVC wallboard manufacturing process usually involves extrusion molding technology, which extrude PVC material through a die into the desired shape and size, and then cool and solidify it to manufacture wallboards of various designs and colors.

[0003] However, the existing PVC wall panel extrusion molding device has some technical disadvantages. The existing device has the problem of uneven temperature during the cooling process. The existing cooling system usually relies on a static cooling water tank or cooling plate. Although this existing cooling method is simple and easy, the cooling water only circulates in one channel and cannot stay on the surface of the wall panel for sufficient heat exchange, resulting in uneven temperature distribution of the wall panel during the cooling process after extrusion molding, and local overheating or insufficient cooling is prone to occur, which not only affects the overall performance of the wall panel, such as strength, hardness, etc., but may also cause deformation, cracking and other problems of the wall panel during subsequent processing or use. If the cooling is performed with full coverage, it will lead to low cooling efficiency and waste a lot of energy and time.

[0031] Reference Figure 1-Figure 3 A PVC wallboard extrusion molding device in an embodiment of the utility model comprises: a base frame 1; a template assembly, comprising a base plate bracket 21 and a panel 22, the base plate bracket 21 is mounted on the base frame 1, the base plate bracket 21 is provided with a plurality of groups of grooves 23, each group of the grooves 23 comprises a main groove 231 and a side groove 232, the side grooves 232 are arranged at intervals along both sides of the length direction of the main groove 231, the depth of the main groove 231 is greater than the side groove 232, and the panel 22 is mounted on the base plate bracket 21; a liquid pump 3, the liquid pump 3 is arranged on the base frame 1, communicated with the base plate bracket 21, and is used to transport cooling liquid to the groove 23 of the template assembly, the cooling liquid flows through the main groove 231 and the side groove 232; an extrusion mechanism, the extrusion mechanism is arranged on the base frame 1, and comprises an extrusion plate 41 corresponding to the panel 22, the extrusion plate 41 reciprocates in a direction perpendicular to the panel 22, thereby realizing extrusion molding of the PVC material.

[0032] In this embodiment, a plurality of groups of grooves 23 are provided on the bottom plate support 21, and each group of grooves 23 includes a main groove 231 and a side groove 232, so that the cooling liquid is fully covered and evenly distributed on the surface of the wallboard. The cooling liquid is transported from the liquid pump 3 to the main groove 231, and then flows through the side groove 232. Since the side grooves 232 are arranged at intervals on both sides along the length direction of the main groove 231, the cooling liquid can be more evenly distributed on the surface of the wallboard under the action of the liquid pump 3, thereby effectively solving the problem of uneven temperature during the cooling process in the prior art. At the same time, since the depth of the main groove 231 is greater than that of the side groove 232, the residence time of the cooling liquid in the wallboard can be increased, so that the cooling liquid and the wallboard can have a more sufficient heat exchange, further improving the cooling effect. In addition, since the cooling liquid flows in the groove 23 of the template assembly, the cooling liquid can continuously exchange heat with the surface of the wallboard, thereby improving the cooling efficiency, and then the PVC material is extruded and formed by the extrusion plate 41 of the extrusion mechanism, thereby ensuring the molding quality of the PVC wallboard. In this embodiment, a gap is provided between every two groups of grooves 23, which effectively solves the problem of material deformation and resource waste caused by comprehensive water cooling of PVC materials in the prior art.

[0033] It is worth noting that in this embodiment, the depth of the main groove 231 in the groove 23 is greater than the side groove 232, in order to achieve more accurate and efficient temperature control during the extrusion molding process of the PVC wallboard, especially in the cooling stage. The depth of the main groove 231 is greater than the side groove 232, and the storage volume of the cooling liquid therein is relatively large. When the extrusion plate 41 extrude the PVC material, the wallboard contacts the cooling liquid in the groove 23 through the panel 22 to exchange heat. Since the main groove 231 is deep and the amount of cooling liquid therein is large, it can absorb more heat and reduce the temperature of the wallboard. Secondly, the side grooves 232 are designed to be arranged at intervals on both sides along the length direction of the main groove 231, and the depth is shallow, which ensures that the cooling liquid can be quickly and evenly distributed to both sides of the wallboard after flowing through the main groove 231, especially in the part of the wallboard. Since the part is often more prone to uneven temperature problems, the design of the side grooves 232 can ensure that the cooling liquid can cover these areas, thereby avoiding quality problems caused by uneven temperature. Furthermore, the design that the depth of the main groove 231 is greater than that of the side groove 232 also helps to improve the cooling efficiency. When the cooling liquid flows from the main groove 231 to the side groove 232, the liquid flow rate will be relatively slow due to the shallow depth of the side groove 232, and the groove diameter of the side groove 232 is smaller than the inner diameter of the groove, so that the cooling liquid flows faster in the main groove 231, but flows slower in the side groove 232, thereby forming a certain liquid residence time, so that the cooling liquid can exchange heat with the wallboard in the side groove 232 for a longer time, fully absorb heat, and improve the cooling effect. At the same time, the circulation of the cooling liquid in the groove 23 can take away the heat and further reduce the temperature of the wallboard, thereby achieving an efficient cooling process. In another embodiment, the liquid pump 3 in this embodiment is connected to the bottom plate bracket 21 through a pipeline, and two liquid inlets are provided on the side of the bottom plate bracket 21 close to the liquid pump 3. The cooling liquid enters the bottom plate bracket 21 through the liquid inlet and is transported to each groove 23 through the pipeline system in the bottom plate bracket 21.

[0034] It is worth noting that Figure 3 It is just a reference schematic diagram, and the pipeline system is not specifically shown in the figure. In practical applications, the pipeline system can be designed and arranged as needed so that the cooling liquid can be evenly and effectively transported to each groove 23.

[0035] In one embodiment, a guide rail 11 is provided on the base frame 1, and the base plate bracket 21 is installed on the guide rail 11 through a slider 12 to achieve reciprocating motion along the guide rail 11 in a direction away from the liquid pump 3; a sliding handle 13 is provided at one end of the base plate bracket 21 away from the liquid pump 3, and the base plate bracket 21 is moved away from the extrusion mechanism by pulling the sliding handle 13.

[0036] In this embodiment, a guide rail 11 is provided on the base frame 1, so that the base plate bracket 21 can reciprocate along the guide rail 11, providing greater flexibility for the molding of the PVC wallboard. By pulling the sliding handle 13, the base plate bracket 21 can be away from the extrusion mechanism, which is convenient for the operator to adjust or maintain the template assembly before extrusion molding. In addition, when the base plate bracket 21 is away from the extrusion mechanism, it also provides sufficient space for the subsequent removal of the wallboard or the placement of new PVC materials, thereby improving production efficiency. Further, during the extrusion molding process, the lateral distance between the base plate bracket 21 and the extrusion mechanism is adjusted according to actual needs. By changing the distance, the force uniformity of the PVC material during the extrusion process can be controlled, and the wallboard can be ensured to remain flat during the molding process. In this embodiment, when the base plate bracket 21 is away from the liquid pump 3, the working state of the liquid pump 3 is adjusted to continue to deliver cooling liquid to the groove 23 of the template assembly. In this way, it can be ensured that during the movement of the wallboard, its surface temperature is always kept within an appropriate range, avoiding quality problems caused by excessive temperature. In an optional embodiment, an electric mechanism can also be provided on the base plate, which is electrically connected to the sliding handle 13 to drive the base plate bracket 21 to reciprocate, so that the cooling liquid can circulate better in the groove 23 of the template assembly. When the base plate bracket 21 moves away from the liquid pump 3, the cooling liquid in the groove 23 will be squeezed and pushed to a certain extent, which helps the liquid to flow in the groove 23, thereby improving the cooling efficiency.

[0037] In one embodiment, the extrusion mechanism also includes a lifting structure, which includes a fixed column 421 and a connecting rod 422. The fixed column 421 is fixedly arranged on the base frame 1, and the fixed column 421 and the connecting rod 422 are connected by a connecting member 423. One end of the connecting rod 422 is connected to the panel 22, and an elastic member 43 is arranged between the other end and the connecting member 423. The elastic member 43 is used to provide a buffering force during the extrusion process.

[0038] In this embodiment, the extrusion mechanism can provide a more stable and uniform extrusion force when extruding the PVC material by adding a lifting structure. Specifically, the lifting structure is composed of a fixed column 421, a connecting rod 422 and an elastic member 43. The fixed column 421 is fixed on the base frame 1 to ensure the stability of the structure. The connecting rod 422 is connected to the fixed column 421 through the connecting member 423, and is connected to the panel 22 at the other end of the connecting rod 422, so that the panel 22 can move up and down with the lifting of the connecting rod 422. The setting of the elastic member 43 plays a key role in the extrusion process. During the extrusion process, as the extrusion plate 41 is pressed down, the connecting rod 422 will be subjected to downward pressure, causing the elastic member 43 to deform. The deformation of the elastic member 43 can absorb part of the extrusion force, thereby avoiding deformation or damage of the wallboard caused by excessive extrusion force. At the same time, the deformation of the elastic member 43 can also provide a stable buffer force for the extrusion process, so that the extrusion force can be more evenly distributed on the wallboard, thereby improving the molding quality of the wallboard. In addition, the setting of the elastic member 43 can also reduce the noise and vibration during the extrusion process, providing a more comfortable working environment for the operator. After the extrusion is completed, as the extrusion plate 41 rises, the connecting rod 422 will also be pulled upward, so that the elastic member 43 gradually recovers its deformation and prepares for the next extrusion process.

[0039] In one embodiment, the extrusion mechanism also includes a driving structure 44, which includes a driving motor and a transmission mechanism. The driving motor is fixedly connected to the side of the connecting member 423, and the transmission mechanism is connected to the output shaft of the driving motor. The transmission mechanism is connected to the connecting rod 422 through a connecting rod to drive the connecting rod 422 to reciprocate up and down along the fixed column 421.

[0040] In this embodiment, the driving structure 44 of the extrusion mechanism adopts a combination of a driving motor and a transmission mechanism, which provides a stable and efficient power source for the extrusion molding of PVC wallboards. The driving motor is a core component, and its output shaft is connected to the connecting rod through a transmission mechanism, thereby driving the connecting rod 422 to reciprocate up and down along the fixed column 421. This design makes the extrusion process more automated, reduces the labor intensity of the operator, and improves production efficiency. At the same time, the precise control of the driving motor also ensures the uniformity and stability of the extrusion force, further improving the molding quality of the wallboard. In addition, the design of the transmission mechanism also fully considers the stability and durability of the structure, so that the entire driving structure 44 can still maintain an efficient and stable working state during long-term operation. In actual applications, the operator can adjust the working parameters of the driving motor according to production needs, such as speed, steering, etc., to meet the extrusion requirements of PVC materials of different specifications and thicknesses. This flexibility makes the extrusion mechanism of this embodiment have a wider range of applicability.

[0041] In one embodiment, a distance increasing plate 5 is further provided between the panel 22 and the connecting rod 422 to increase the contact area between the panel 22 and the connecting rod 422 .

[0042] In this embodiment, the distance-increasing plate 5 added between the panel 22 and the connecting rod 422 not only increases the contact area between the panel 22 and the connecting rod 422, but also effectively improves the stability during the extrusion process. The distance-increasing plate 5 can withstand a large extrusion force and friction force, ensuring that the panel 22 will not be deformed or damaged due to uneven force during the up and down movement. At the same time, the design of the distance-increasing plate 5 can also disperse the extrusion force, reduce the wear between the connecting rod 422 and the panel 22, and extend the service life of the equipment. During the extrusion process, the distance-increasing plate 5 maintains close contact with the connecting rod 422 and the panel 22, forming a stable support structure. When the drive motor is started and the connecting rod 422 is driven up and down by the transmission mechanism, the distance-increasing plate 5 can ensure the synchronous movement between the panel 22 and the connecting rod 422, avoiding the quality problem of wallboard forming caused by inconsistent movement. In addition, the distance-increasing plate 5 can also effectively prevent the material leakage caused by the gap between the panel 22 and the connecting rod 422 during the extrusion process, ensuring the integrity and accuracy of the wallboard forming. The provision of the distance-increasing plate 5 not only improves the stability and durability of the extrusion mechanism, but also provides the operator with a more convenient adjustment and maintenance method. When it is necessary to adjust the distance between the panel 22 and the connecting rod 422, it is only necessary to replace the distance-increasing plate 5 of the corresponding thickness, without the need to disassemble and reinstall the entire extrusion mechanism. This design greatly reduces maintenance costs and time costs, and improves production efficiency. In summary, the application of the distance-increasing plate 5 in the PVC wall panel extrusion molding equipment not only improves the stability and durability of the equipment, but also reduces maintenance costs and time costs, providing a strong guarantee for the production of high-quality and high-efficiency PVC wall panels.

[0043] In one embodiment, a plurality of air holes 6 are provided on the extruded plate 41 of the template assembly, and the air holes 6 include a first part and a second part, the first part is provided close to the panel 22, the second part is connected to the first part, and the aperture of the second part is larger than the aperture of the first part.

[0044] In this embodiment, the extrusion plate 41 of the template assembly is designed with a vent hole 6, which not only improves the air permeability of the PVC wallboard during the molding process, but also further optimizes the molding quality of the product. The design of the vent hole 6 is divided into two parts, the first part is arranged close to the panel 22, and the second part is connected to the first part, and the aperture of the second part is larger than that of the first part. This design allows the air inside the PVC material to be discharged more smoothly during the extrusion process, reducing the generation of bubbles, thereby improving the density and flatness of the wallboard. Specifically, when the extrusion plate 41 begins to press down, the air inside the PVC material begins to be discharged outward through the first part of the vent hole 6 while the PVC material is being squeezed. Since the aperture of the first part is small, it can effectively prevent the PVC material from overflowing due to excessive pressure during the extrusion process. At the same time, as the extrusion process proceeds, when the PVC material is further compressed, the air inside it begins to be discharged more through the second part of the vent hole 6. Since the aperture of the second part is large, the air can be discharged more quickly, further improving the air permeability of the wallboard.

[0045] In one embodiment, a telescopic rod 7 is further included, one end of which is connected to the base frame 1 , and the other end of which is connected to the extrusion plate 41 to assist the extrusion plate 41 in reciprocating motion.

[0046] In this embodiment, one end of the telescopic rod 7 is connected to the base frame 1, and the other end is connected to the extrusion plate 41, forming a stable support structure. During the extrusion process, the telescopic rod 7 is extended and retracted with the movement of the extrusion plate 41, effectively maintaining the stability of the extrusion plate 41 and preventing the quality problems of the wallboard molding caused by vibration or shaking. The design of the telescopic rod 7 not only takes into account its stability and durability, but also pays attention to the convenience of operation. In practical applications, the operator can adjust the length of the telescopic rod 7 as needed to meet the production requirements of PVC wallboards of different specifications. In addition, the telescopic rod 7 also has a certain buffering effect. During the extrusion process, when the extrusion plate 41 is subjected to a large extrusion force, the telescopic rod 7 can be deformed to a certain extent to absorb part of the extrusion force. This buffering effect can reduce the noise and vibration during the extrusion process, further improving the stability and durability of the equipment.

[0047] In one embodiment, the adjustment member is arranged on a side of the extrusion plate 41 close to the base plate bracket 21, and the adjustment member includes an adjustment bolt 81 and an adjustment plate 82. The adjustment bolt 81 passes through the extrusion plate 41 and is threadedly connected to the adjustment plate 82. The adjustment plate 82 is arranged parallel to the extrusion plate 41. The adjustment bolt 81 is rotated to drive the adjustment plate 82 to approach or move away from the panel 22, thereby adjusting the gap between the extrusion plate 41 and the panel 22.

[0048] In this embodiment, the setting of the adjustment member enables the gap between the extrusion plate 41 and the panel 22 to be accurately adjusted, thereby ensuring the accuracy and stability of the wallboard molding. The combined design of the adjustment bolt 81 and the adjustment plate 82 makes the adjustment process more convenient and fast, and can be completed without complicated operations. Specifically, when the gap between the extrusion plate 41 and the panel 22 needs to be adjusted, the operator only needs to rotate the adjustment bolt 81. Since the adjustment bolt 81 is threadedly connected to the adjustment plate 82, when the adjustment bolt 81 is rotated, the adjustment plate 82 will be closer to or farther away from the panel 22 accordingly. This design makes the adjustment process have higher accuracy and flexibility, and can adapt to the extrusion requirements of PVC materials of different specifications and thicknesses. At the same time, the setting of the adjustment member also has a certain degree of safety. During the adjustment process, the adjustment plate 82 is arranged in parallel with the extrusion plate 41, which can effectively prevent equipment damage or safety accidents caused by improper adjustment. In addition, the threaded connection structure of the adjustment bolt 81 also ensures the stability and reliability of the adjustment process. In summary, the application of the adjustment member in the PVC wallboard extrusion molding equipment not only improves the accuracy and stability of the equipment, but also enhances the safety and reliability of the equipment. This design enables the equipment to better adapt to the extrusion requirements of PVC materials of different specifications and thicknesses, providing a strong guarantee for the production of high-quality and high-efficiency PVC wall panels.

[0049] In one embodiment, a plurality of fixing grooves 9 are arranged at intervals on the guide rail 11, and the slider 12 is provided with a protrusion matching the fixing groove 9. By adjusting the position of the slider 12 on the guide rail 11, the base plate bracket 21 is aligned with the fixing groove 9, and the protrusion is inserted into the fixing groove 9, so as to fix the base plate bracket 21.

[0050] In this embodiment, the fixed grooves 9 arranged at intervals on the guide rail 11 and the protrusion design on the slider 12 provide a flexible and reliable way to fix the bottom plate bracket 21, which not only simplifies the installation and disassembly process, but also improves the stability and safety of the equipment. Specifically, when the position of the bottom plate bracket 21 needs to be adjusted, the slider 12 is moved on the guide rail 11 until the bottom plate bracket 21 is aligned with the required fixed groove 9. Then the protrusion on the slider 12 is inserted into the fixed groove 9 to achieve the fixation of the bottom plate bracket 21. The adjustment process is simple and quick, and no additional tools or complicated operations are required. In addition, the matching design of the fixed groove 9 and the protrusion ensures the stability and reliability of the bottom plate bracket 21 after fixation. Since the protrusion can be completely inserted into the fixed groove 9, the bottom plate bracket 21 will not shake or displace when subjected to the extrusion force, thereby ensuring the accuracy and consistency of the wallboard molding. This design also has a certain impact resistance, which can effectively resist the influence of external factors (such as vibration, impact, etc.) on the equipment, and further improves the stability and durability of the equipment.
