[0001] The utility model relates to the technical field of stone plastic floor processing, in particular to a calendering device for SPC stone plastic floor. Background Art

[0002] SPC stone plastic flooring is a green and environmentally friendly composite material with good wear resistance. It is formed by high-temperature hot pressing of natural stone powder and PVC resin and covered with a super wear-resistant polymer PVC wear-resistant layer to form a solid base with high density and high fiber mesh structure. During the calendering process, the heat transfer oil is usually heated from one end of the calendering roller to the other end. When heating, the temperature difference between the two ends will appear. In the long-term use process, the calendering equipment needs regular maintenance.

[0003] According to Chinese patent publication number CN116352949A, "A calendering device and process for SPC stone plastic flooring", it mainly describes that through the temperature control adjustment mechanism, not only can multiple calendering rollers be independently temperature-controlled and adjusted, but also when heating the calendering rollers, the calendering rollers can be evenly heated by bidirectionally transporting heat-conducting oil into bidirectional oil pipes, effectively preventing temperature differences on the same calendering rollers and effectively preventing deformation of the SPC stone plastic flooring after calendering. During this process, the calendering rollers used to support the bidirectional oil supply are not in direct contact with the pressing rollers, resulting in low heat conduction efficiency.

[0004] Therefore, a calendering device for SPC stone plastic floor is proposed to solve the problem that in the process, the calendering roller used to support the two-way oil delivery is not in direct contact with the pressing roller, resulting in low heat conduction efficiency.

A driving motor is set on one side of the roller 2, and the driving motor controls the rotation of the roller 2, thereby prompting the conveyor belt 3 to rotate. A limiting groove 4 is provided on the connecting frame 1, and a screw 5 is rotatably connected in the limiting groove 4. A moving block 6 is threadedly connected to the screw 5. Rotating the screw 5 can make the auxiliary roller 23 contact the stone plastic floor and its material. The moving block 6 is hollow, and a partition is fixedly connected to the moving block 6, and heating pipes 7 are fixedly connected to the upper and lower sides of the moving block 6. One side of the moving block 6 is fixedly connected to the driving motor and the output end of the driving motor is fixedly connected to the rotating rod 9. One end of the rotating rod 9 is fixedly connected to the support plate 8. The driving motor drives the rotation The rod 9 and the support plate 8 rotate, and can drive the pressure roller 15 to rotate under the action of the bracket 13. The upper side of the support plate 8 is rotatably connected to the first annular plate 11 through a sealed bearing. The first annular plate 11 is rotatably connected to the annular cavity 10 through a sealed bearing. A separator ring 17 is fixedly connected in the annular cavity 10. One side of the rotating rod 9 is fixedly connected to the guide cover 12. The outer side of the guide cover 12 is fixedly connected to the bracket 13. The bracket 13 is fixedly connected to the pressure roller 15. One end of the guide cover 12 is fixedly connected to the spiral tube 14. One side of the other annular cavity 10 is fixedly connected to the output pipe 16. The output pipe 16 is communicated with the inside of the moving block 6. One side of the annular cavity 10 is rotatably connected to the second annular plate 18 through a sealed bearing. The moving block 6 is fixedly connected to the input pipe 20, and the input pipe 20 is communicated with the annular cavity 10. Both moving blocks 6 are fixedly connected to the water pump 19. Figure 2 From the perspective of the embodiment, the left water pump 19 draws external heat transfer oil through the left movable block 6, and after being heated by the heating tube 7 on the outside of the two partitions, it enters the guide cover 12 through the first annular plate 11 through the input pipe 20, and then enters the right guide cover 12 through the spiral tube 14, and moves out of the equipment through the inner side of the separating ring 17 and the input pipe 20 on the other side. Then, the right water pump 19 draws external heat transfer oil through the output pipe 16 and guides it to the heating tube 7 at the partition and the rotating rod 9 for heating, and then passes through the second annular plate 18 into the inner cavity of the pressure roller 15, and is blocked by multiple baffles 28. The oil inlet efficiency on both sides is synchronized, thereby achieving two-way oil inlet and the oil body directly contacts the pressure roller 15, which promotes the efficiency of heat conduction.

[0018] Among them, the conveyor belt 3 corresponds to the auxiliary roller 23, the auxiliary roller 23 is rotatably connected to the moving frame 22 through the rotating shaft, the moving frame 22 is fixedly connected to the output end of the electric push rod 21, and the electric push rod 21 is fixedly connected to the connecting frame 1. The moving frame 22 is controlled to move up and down by the electric push rod 21, and the auxiliary roller 23 is made to contact the stone plastic floor and the material on its surface. The effect of being parallel to the bottom end of the pressure roller 15 can be achieved by controlling the extension and contraction of the electric push rod 21.

[0019] Among them, an auxiliary gear 26 is fixedly connected to the rotating shaft, the auxiliary gear 26 engages with the main gear 25, the main gear 25 is fixedly connected to the output end of the driving motor, the driving motor is fixedly connected in the support frame 24, and the support frame 24 is fixedly connected in the moving frame 22. By setting the driving motor and prompting the auxiliary gear 26 and the main gear 25 to rotate, the auxiliary roller 23 and the pressure roller 15 can form an advantage of synchronous rotation.

[0020] The connecting frame 1 is fixedly connected to the pad 27, and the pad 27 contacts the inner side of the conveyor belt 3. By providing the pad 27, the stability of the stone plastic floor supported on the conveyor belt 3 can be increased.

[0021] Among them, the baffle plate 28 is fixedly connected to the spiral tube 14, and the baffle plate 28 is located in the auxiliary roller 23. The auxiliary roller 23 is hollow. By setting the baffle plate 28, the contact surface of the oil body can be increased, thereby improving the temperature conduction efficiency when the oil is introduced.

[0022] Working principle: Adjust the screw 5 to move the moving block 6 downward, and make the gap between the pressure roller 15 and the conveyor belt 3 correspond to the stone plastic floor. After the mixing equipment mixes the materials, they fall between the two pressure rollers 15. Then the stone plastic floor is placed on the conveyor belt 3 and continues to move. Then the electric push rods 21 on both sides of the pressure roller 15 are started respectively, so that the auxiliary rollers 23 respectively adapt to the height of the stone plastic floor and the surface of the stone plastic bottom edge after the material is attached. The left water pump 19 draws the external heat transfer oil through the left moving block 6, and after being heated by the heating pipe 7 on the outside of the two partitions, it is then passed through the first annular plate 11 through the input pipe 2 0 enters the guide cover 12, then uses the spiral tube 14 to enter the right guide cover 12, and moves out of the equipment through the inner side of the separation ring 17 and the input pipe 20 on the other side. Then the right water pump 19 extracts the external heat transfer oil and guides it to the heating pipe 7 at the partition and the rotating rod 9 through the output pipe 16. After heating, it passes through the second annular plate 18 and enters the inner cavity of the pressure roller 15, and is blocked by multiple baffles 28. The oil inlet efficiency on both sides is synchronized, thereby achieving two-way oil inlet and the oil body directly contacts the pressure roller 15, which promotes the efficiency of heat conduction. The heated material falls onto the stone plastic floor and is rolled and bonded to the surface of the stone plastic floor.
