Description

Technical Field

[0001] This utility model relates to the field of flooring processing technology, and in particular to a hot pressing device for PVC flooring processing. Background Technology

[0002] PVC flooring, also known as polyvinyl chloride flooring, is a new type of lightweight floor decoration material. The patterns of PVC flooring can be customized according to customer needs, thanks to the plasticity of its production process, the flexibility of its design, and the diversity of market demands. Therefore, PVC flooring is popular in the market for its diverse surface patterns.

[0003] When processing PVC flooring patterns, two molds are usually used. The PVC flooring is placed between the two molds and then heated. The heated PVC flooring is then extruded by the two molds to form the pattern. However, different molds need to be changed when processing different shapes of patterns. Most of the current molds are assembled and disassembled with bolts, which is a complicated and inconvenient process. Utility Model Content

[0024] Reference Figures 1-5 This utility model proposes a hot-pressing device for processing PVC flooring, including a base 1 and a top plate 2. A lower mold is fixedly installed on the top surface of the base 1, thus the top surface of the base 1 serves as the lower mold. The top plate 2 is located directly above the base 1, and an mounting plate 3 is installed at the bottom of the top plate 2. An upper mold 4 is detachably installed on the bottom surface of the mounting plate 3. A quick-release structure is provided between the mounting plate 3 and the upper mold 4. A driving structure capable of adjusting the distance between the upper mold 4 and the base 1 is installed on the top plate 2. The driving structure includes a hydraulic rod 13; the hydraulic rod 13 is vertically installed on the top plate. 2. Mounting plate 3 is fixedly mounted on the output shaft of hydraulic rod 13. During the hot pressing of PVC flooring, the PVC flooring is laid flat on the top surface of base 1 and heated. Then, the hydraulic rod 13 drives the mounting plate 3 and upper mold 4 to descend. The upper mold 4 and base 1 extrude the PVC flooring into shape. When processing different 3D patterns, different upper molds 4 are required. Therefore, a quick-release structure is needed to quickly disassemble and replace the new upper mold 4, reducing the tedious steps for workers when replacing the upper mold 4 and improving work efficiency.

[0025] like Figure 2 , Figure 3 and Figure 4As shown, the quick-release structure includes a mounting block 5, an arc-shaped insert pin 6, and a drive assembly. The mounting block 5 is fixedly mounted on the top surface of the upper mold 4. The bottom surface of the mounting plate 3 has a mounting groove adapted to the mounting block 5. The mounting plate 3 has a moving hole that slides with the arc-shaped insert pin 6. The side of the mounting block 5 has an insertion hole 7 adapted to the arc-shaped insert pin 6. The drive assembly is used to drive the arc-shaped insert pin 6 in and out of the insertion hole 7. The insertion holes 7 are distributed on both sides of the mounting block 5. The end of the arc-shaped insert pin 6 can abut against the inner wall of the end of the insertion hole 7. When the arc-shaped insert pin 6 rotates and abuts against the inner wall of the end of the insertion hole 7, the mounting block 5 can... There is a tendency for the mounting block to move into the mounting groove. When disassembling the upper mold 4, the drive assembly drives the arc-shaped insert pin 6 to rotate and disengage from the insertion hole 7 of the mounting block 5, and the mounting block 5 can be removed from the mounting groove. During installation, the mounting block 5 on the upper mold 4 is inserted into the mounting groove on the bottom surface of the mounting plate 3. Then, the drive assembly drives the arc-shaped insert pin 6 to rotate and insert into the insertion hole 7. When the end of the arc-shaped insert pin 6 abuts against the inner wall of the end of the insertion hole 7, the mounting block 5 will retract in the mounting groove, so that the top surface of the mounting block 5 is close to the top inner wall of the mounting groove, reducing gaps and ensuring the molding quality of the PVC floor during hot pressing.

[0026] like Figure 2 and Figure 3 As shown, the drive assembly includes sector gears 8 and a rotating shaft 9. The number of sector gears 8 is the same as the number of arc-shaped insert pins 6 and they are set one-to-one. A rotating groove is opened in the mounting plate 3 to rotate and cooperate with the sector gears 8. One end of the arc-shaped insert pin 6 is fixedly connected to the sector gear 8. Multiple sector gears 8 are fixedly connected to a rotating shaft 9. The rotating shaft 9 is rotatably installed in the mounting plate 3. A motor for driving the rotating shaft 9 is installed on the mounting plate 3. When driving multiple arc-shaped insert pins 6 to rotate, the motor drives the rotating shaft 9 to rotate, and the rotating shaft 9 drives multiple sector gears 8 and multiple arc-shaped insert pins 6 to move synchronously, which facilitates the disassembly and assembly of the upper mold 4.

[0027] like Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the quick-release structure also includes stabilizing blocks 10 and locking components. Multiple stabilizing blocks 10 are fixedly connected to the top surface of the mounting block 5. The inner wall of the mounting groove has mounting holes adapted to the stabilizing blocks 10. The locking components are used to fix the position of the stabilizing blocks 10 within the mounting holes. The multiple stabilizing blocks 10 are arranged in a matrix. In practice, although the sides of the mounting block 5 are fixed, gaps may appear between the top surface of the mounting block 5 and the top inner wall of the mounting groove. During hot pressing, these gaps may affect the pattern quality of the PVC flooring. Therefore, multiple stabilizing blocks 10 arranged in a matrix are provided on the top of the mounting block 5. The locking components fix the stabilizing blocks 10 within the mounting holes, thereby fixing the middle top position of the mounting block 5. This ensures that the middle top position of the mounting block 5 and the top inner wall of the mounting groove remain stable during hot pressing, reducing movement during hot pressing and minimizing its impact on the quality of the PVC flooring.

[0028] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the locking assembly includes a connecting rod 11 and an L-shaped locking pin 12; the mounting plate 3 has a transverse groove that slides with the connecting rod 11; the L-shaped locking pin 12 is fixedly installed on the connecting rod 11; the stabilizing block 10 has an insertion hole that matches the bent section of the L-shaped locking pin 12; the transverse section of the L-shaped locking pin 12 can be inserted into the insertion hole; multiple L-shaped locking pins 12 are arranged on the same connecting rod 11; the number of connecting rods 11 is the same as the number of sector gears 8 and they are arranged one-to-one; the connecting rod 11 meshes with the sector gears 8; the top surface of the bent section of the L-shaped locking pin 12 is an inclined surface; the inclined surface on the L-shaped locking pin 12 slides with the inner wall of the insertion hole; when installing a new upper mold 4, the locking mechanism is adjusted by... The motor drives the rotating shaft 9 to rotate, and the two rotating shafts 9 will drive multiple sector gears 8 to rotate. The rotating sector gears 8 will drive multiple arc-shaped insert pins 6 to insert into the corresponding insert holes 7. When the sector gears 8 rotate, they will drive the connecting rod 11 to slide synchronously. The sliding connecting rod 11 will drive the L-shaped locking pin 12 to insert into the corresponding insertion hole of the stabilizing block 10. After the L-shaped locking pin 12 is inserted into the insertion hole, the inclined surface of the horizontal section of the L-shaped locking pin 12 fits against the inner wall of the insertion hole, so that the stabilizing block 10 is retracted into the insertion hole, so that the top surface of the mounting block 5 fits more closely against the top inner wall of the mounting groove, reducing the gap between the two and reducing the displacement caused by the gap during the hot pressing process, which affects the quality of the PVC floor.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
