Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0030] Referring to Figures 1 to 4 An adjustable thickness PVC hollow composite tile production device, comprising a bearing frame 1, an upper mold 2, a lower mold 3, a conveying assembly 4, an electric drive assembly 5, a scale 6 and an angle plate 7.

[0031] In this embodiment, the bearing frame 1 is the basic support structure of the entire production device, which is welded by Q235 steel plate and has sufficient strength and stability to provide space for the installation and operation of other components. The upper mold 2 is fixed on the top of the bearing frame 1 by high-strength bolts and is fixed in position. Its role is to cooperate with the lower mold 3 to apply pressure to the PVC material during the molding process of the PVC hollow composite tile, and to shape the upper half of the composite tile. The lower mold 3 is connected to the inside of the bearing frame 1 through a T-shaped guide rail and can slide horizontally along the guide rail. The lower mold 3 is arranged opposite to the upper mold 2 and works together with the upper mold 2 to complete the compression molding of the PVC hollow composite tile. Its sliding design is used to adjust the thickness of the composite tile. The conveying assembly 4 is installed on the top of the bearing frame 1 and is composed of a conveying belt, a drive roller and a motor 19. The motor 19 drives the drive roller to rotate, which in turn drives the conveying belt to convey the PVC raw material to the working area between the upper and lower molds 3, ensuring the continuity of the production process. The electric drive assembly 5 is installed at the bottom of the bearing frame 1 and is composed of a motor 19, a speed reducer and a screw nut transmission mechanism. The motor 19 drives the screw nut mechanism to convert the rotary motion into linear motion after being decelerated by the speed reducer, providing power for the sliding of the lower mold 3 and accurately controlling the moving distance and speed of the lower mold 3, thus realizing the adjustment of the thickness of the PVC hollow composite tile. The scale 6 is pasted on the side of the bearing frame 1 by AB glue and has scale values marked on it, which is used to intuitively display the position information of the lower mold 3 and reflect the thickness adjustment amount of the PVC hollow composite tile. The angle plate 7 is L-shaped and made of stainless steel plate, which is fixed on the side of the lower mold 3 by welding. One of the right-angle edges of the angle plate 7 closely fits the side of the lower mold 3, and the other right-angle edge contacts the scale 6. With the movement of the lower mold 3, the position of the lower mold 3 can be read from the scale 6, and thus the adjustment of the thickness of the composite tile can be known. The bearing frame 1 provides stable support for the entire device, ensuring that other components can operate normally. The conveying assembly 4 continuously conveys the PVC raw material to the working area, ensuring uninterrupted production. The electric drive assembly 5 drives the lower mold 3 to slide in the bearing frame 1, cooperates with the fixed upper mold 2 to realize the compression of the PVC material, and accurately controls the position of the lower mold 3 to change the thickness of the composite tile. The scale 6 works with the angle plate 7, and the angle plate 7 moves with the lower mold 3, allowing the operator to intuitively obtain the position of the lower mold 3 from the scale 6 and thus master the thickness adjustment value of the composite tile, ensuring the production of PVC hollow composite tiles that meet different thickness requirements. Each component works closely together to realize the efficient production of PVC hollow composite tiles with automatic adjustment of the thickness.

[0032] First, refer to Figure 4 In this embodiment, the electric drive assembly 5 includes a bottom support 8, which is fixed by welding at the bottom of the lower mold 3, and the two are connected stably to ensure that the bottom support 8 can support the lower mold 3, and the bottom support 8 provides a bearing base for the lower mold 3, so that the lower mold 3 maintains a stable position during the molding process. The two sides of the bearing frame 1 are provided with a screw rod 9 through a bearing, and the axis of the screw rod 9 is perpendicular to the side of the bearing frame 1. The screw rod 9 is connected with the two sides of the bottom support 8 through threads. When the screw rod 9 rotates, the bottom support 8 will move axially along the screw rod 9, so as to realize the position change of the bottom support 8 by rotating the screw rod 9. The bottom of the bearing frame 1 is fixedly provided with a support assembly 10 by welding. The support assembly 10 provides support for the entire electric drive assembly 5 to ensure its working stability. The support assembly 10 is perpendicular to the bottom of the bearing frame 1 and bears the weight of the components above. A power assembly 11 is installed on the support assembly 10, which is usually a driving device such as a motor 19 and is connected with the screw rod 9 through a shaft coupling and other components. The power assembly 11 outputs rotary power after starting to drive the screw rod 9 to rotate, thereby realizing the movement of the bottom support 8.

[0033] The above-mentioned parts cooperate with each other. The power assembly 11 drives the screw rod 9 to rotate. The screw rod 9 moves the bottom support 8 up and down through thread transmission to adjust the height position of the lower mold 3, meet the stamping molding requirements of different specifications of glass steel purlins, and guarantee the working stability of the entire electric drive assembly 5. The support assembly 10 bears each component to complete the molding operation of the glass steel purlin in cooperation with other device components.

[0034] Then, refer to Figure 3 In this embodiment, the support assembly 10 includes support columns 12, which are fixed vertically on the bottom of the bearing frame 1 by welding and are uniformly distributed around the bottom of the bearing frame 1. Its role is to provide vertical support force for the bearing frame 1 and transmit the weight of the bearing frame 1 and the related components above to the ground to ensure the vertical stability of the entire device. The support seat 13 is fixed between each support column 12 by welding and is in a horizontal state. It connects each support column 12 as a whole, enhances the overall structural strength of the support assembly 10, makes the support column 12 can more evenly share the weight, avoids uneven stress of a single support column 12, and at the same time provides an installation platform for the power assembly 11 to ensure the stability of the installation of the power assembly 11.

[0035] Second, refer to Figure 4In the embodiment, the power assembly 11 comprises a first bevel gear 14 fixed at the bottom of the screw rod 9 by key connection, the axis of which coincides with the axis of the screw rod 9, which is used to convert the power transmitted by other components into torque to drive the screw rod 9 to realize the lifting control of the base support 8. The mounting frame 15 is fixed on the top of the support base 13 by welding, which provides the mounting and supporting structure for the rotating shaft 16. The mounting frame 15 is made of metal material, which has certain strength and stability to ensure the stability of the rotating shaft 16 during rotation. The rotating shaft 16 is installed on the mounting frame 15 by bearing and can rotate freely in the mounting frame 15. The two ends of the rotating shaft 16 are fixed with the second bevel gear 17 by key connection, and the first gear 18 is also fixed in the middle of the shaft body by key connection. The rotating shaft 16, as a key component for power transmission, transmits the power of the second bevel gear 17 to the first gear 18 to realize the transmission of power in different directions. The second bevel gear 17 is engaged with the first bevel gear 14, and the number of teeth and the module are matched with the first bevel gear 14 to ensure good meshing transmission effect. When the second bevel gear 17 rotates, the first bevel gear 14 is driven to rotate through meshing, and then the screw rod 9 is driven to rotate. The first gear 18 is fixed on the rotating shaft 16 and rotates synchronously with the rotating shaft 16, which is used to receive the power transmitted by the second gear 20 on the output shaft of the motor 19 and transmit the power to the rotating shaft 16 to indirectly drive the screw rod 9. The motor 19 is installed on the top of the support base 13 by bolts, and the axis of the output shaft of the motor 19 is parallel to the axis of the first gear 18. The motor 19 serves as the power source of the whole power assembly 11 and provides rotary power. The second gear 20 is fixed on the output shaft of the motor 19 by key connection and rotates synchronously with the output shaft of the motor 19. The second gear 20 is engaged with the first gear 18 to transmit the power output by the motor 19 to the first gear 18. After the motor 19 is started, the output shaft drives the second gear 20 to rotate, the second gear 20 drives the first gear 18 to rotate through meshing, the first gear 18 drives the rotating shaft 16 to rotate, and the second bevel gears 17 at both ends of the rotating shaft 16 drive the first bevel gear 14 through meshing, and then the screw rod 9 rotates to realize the control of the position of the base support 8, which meets the needs of adjusting the position of the mold during the forming process of the glass steel purline.

[0036] Again, refer to Figure 2In the embodiment, the conveying assembly 4 comprises a conveying pipe 21 which is horizontally fixed on the top of the bearing frame 1 by welding, and one end of the conveying pipe 21 is communicated with the upper mold 2, so that the material can enter the upper mold 2 through the conveying pipe 21. The conveying pipe 21 provides a conveying channel for the material from the conveying frame 22 to the upper mold 2, so as to ensure that the material can accurately reach the processing position. The conveying frame 22 is fixed on the top of the conveying pipe 21 and is also connected by welding. The conveying frame 22 is provided with a conveyor 23 on the side surface by bolt fixing. The conveying frame 22 serves as a temporary storage and conveying starting point of the material, and provides a mounting platform for the conveyor 23, and contains the material to be conveyed. The conveyor 23 is installed on the side surface of the conveying frame 22, and is generally a screw conveyor, a belt conveyor or the like. After the conveyor 23 is started, power is generated to push the material in the conveying frame 22 to the conveying pipe 21, so as to realize quantitative or continuous conveying of the material and ensure that the material enters the upper mold 2 stably.

[0037] In addition, referring to Figure 3 In the embodiment, the material pressing assembly 24 comprises a gas cylinder 25 which is horizontally fixed on the top of the conveying frame 22 by bolts, and the installation position ensures that the output shaft of the gas cylinder 25 is vertically downward. The gas cylinder 25 serves as a power source and provides driving force for the movement of the pressing ring 26. The pressing ring 26 is slidably arranged on the inner wall of the conveying frame 22 and can move vertically up and down along the inner wall. The top of the pressing ring 26 is fixedly connected with the output shaft of the gas cylinder 25 by welding. When the gas cylinder 25 is started, the output shaft drives the pressing ring 26 to move downward, so as to apply pressure to the material in the conveying frame 22 and compact the material. This prevents the material from loosening and blocking during the conveying process, and ensures that the material can be pushed to the conveying pipe 21 by the conveyor 23 uniformly and stably.

[0038] Finally, referring to Figure 2 In the embodiment, a shock absorber 27 is also provided. One end of the shock absorber 27 is fixed on the bottom of the bearing frame 1 by welding, and the other end is also connected with the bottom support 8 by welding. The shock absorber 27 plays a role of buffering and damping between the bearing frame 1 and the bottom support 8. When vibration occurs during the operation of the device, the shock absorber 27 can absorb and disperse the vibration energy, reduce the influence of vibration on the components of the device, ensure the stability of the operation of the device, and prolong the service life of the device.
