Description

Technical Field

[0001] This utility model relates to the technical field of PVC flooring processing equipment, and more specifically, to a PVC flooring circulating heating segmented pressing edge forming device. Background Technology

[0002] PVC flooring, also known as polyvinyl chloride flooring, is an elastic floor decoration material made from polyvinyl chloride resin as the main raw material, with the addition of plasticizers, stabilizers, pigments and other auxiliary materials, through calendering, coating and lamination processes. It is divided into rolls and sheets, and is a very popular new type of lightweight floor decoration material in the world today.

[0003] In existing technology, during the edge pressing process of PVC flooring, for thicker PVC flooring, it can be pressed in sections. A heat transfer oil circulation system is usually used to heat the pressure rollers, which are then used to press the PVC flooring edges. This is currently the most mainstream heating method in industrial production. However, there are some problems in its use. Ordinary pressure rollers cannot adjust the heating range. Since different models of PVC flooring have different widths, using the same pressure rollers to press the PVC flooring edges will result in wasted heat energy. Replacing the pressure rollers will affect work efficiency. Utility Model Content

[0004] The purpose of this invention is to solve the problem of heat energy waste caused by the inability to adjust the heating range of the pressure roller, and to design a PVC flooring circulating heating segmented pressing edge forming device.

[0005] The technical solution of this utility model to achieve the above objectives is a PVC flooring circulating heating segmented pressing and forming device, including a worktable, through which the PVC flooring can pass. Two sets of pressure rollers are installed at the upper end of the worktable, and the PVC flooring passes between the two sets of pressure rollers. Limiting cylinders are installed at both ends of the pressure rollers, and rolling bearings are installed on the outer side of the limiting cylinders. Multiple support plates are installed on the worktable, and the rolling bearings are installed on the support plates. A circular through hole is opened in the middle of the pressure roller, and a heat-conducting cylinder is installed in the circular through hole. The heat-conducting cylinder can extend and retract within the circular through hole to adjust the heating area. Two constant temperature chambers are installed on the worktable, and heat-conducting oil is contained in the constant temperature chambers. The heat-conducting oil flows in the constant temperature chambers and the heat-conducting cylinders through a circulating pump. The temperature of the heat-conducting oil in the two constant temperature chambers is different.

[0006] Furthermore, the heat-conducting cylinder includes a fixed cylinder fixedly installed in the middle of a circular through hole, and movable cylinders are provided on both sides of the fixed cylinder. The movable cylinders and the fixed cylinder are connected by multiple oil guide pipes.

[0007] Furthermore, a sealed bearing is installed on the outer surface of the movable cylinder, and an oil inlet pipe is installed at the outlet end of the circulating pump. One end of the oil inlet pipe extends into a sealed bearing, and a return oil pipe is installed in the other sealed bearing. The outlet end of the return oil pipe extends into the constant temperature chamber. The portion of the oil inlet pipe and the return oil pipe inside the sealed bearing is a rigid pipe, and the portion outside the sealed bearing is a flexible pipe. Two circulating pumps are installed on each constant temperature chamber, and each circulating pump allows the heat transfer oil to flow in the corresponding heat transfer cylinder and constant temperature chamber.

[0008] Furthermore, the circular through hole is provided with multiple heat-conducting grooves, which are evenly distributed in a circle within the circular through hole. The multiple heat-conducting grooves are located on both sides of the fixed cylinder. Multiple first heat-conducting pipes are installed at both ends of the fixed cylinder, and the first heat-conducting pipes extend into the heat-conducting grooves. Multiple second heat-conducting pipes are installed on the side surface of the movable cylinder near the fixed cylinder. The number of second heat-conducting pipes is the same as the number of first heat-conducting pipes, and the second heat-conducting pipes are located inside the first heat-conducting pipes.

[0009] Furthermore, the oil guide pipe is a flexible pipe, which is located between the second heat guide pipe and the first heat guide pipe and connects the second heat guide pipe and the first heat guide pipe at the corresponding positions.

[0010] Furthermore, movable heat-insulating sleeves are fitted at both ends of the pressure roller.

[0011] The beneficial effects of this utility model are as follows: the heat-conducting cylinder can extend and retract within the pressure roller to adjust the heating range. For wider PVC flooring, a larger heating range can be used, and for narrower flooring, a smaller heating range can be used, which can reduce heat energy waste. The circulating pump allows the heat-conducting oil to flow between the constant temperature box and the heat-conducting cylinder, which facilitates heating of the pressure roller. By using two sets of pressure rollers to press the PVC flooring edges in sections, hot pressing can be easily performed, preventing air bubbles from forming on the surface of the PVC flooring, ensuring the flooring is flat, and improving the hot pressing effect.

Furthermore, in the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0019] This utility model provides, for example Figure 1-4 The PVC flooring circulating heating segmented pressing and forming device shown includes a workbench 1, through which the PVC flooring can pass. Two sets of pressure rollers 2 are installed on the upper end of the workbench 1, and the PVC flooring passes between the two sets of pressure rollers 2. Limiting cylinders 3 are installed at both ends of the pressure rollers 2, and rolling bearings 4 are installed on the outer side of the limiting cylinders 3. Multiple support plates 5 are installed on the workbench 1, and the rolling bearings 4 are installed on the support plates 5. A circular through hole 6 is opened in the middle of the pressure roller 2, and a heat-conducting cylinder 7 is installed in the circular through hole 6. The heat-conducting cylinder 7 can extend and retract within the circular through hole 6 to adjust the heating area. Two constant temperature chambers 8 are installed on the workbench 1. The constant temperature chambers 8 are filled with heat-conducting oil 9. The heat-conducting oil 9 flows in the constant temperature chambers 8 and the heat-conducting cylinder 7 through a circulating pump 10. The temperature of the heat-conducting oil 9 in the two constant temperature chambers 8 is different.

[0020] The process of pressing the PVC flooring edges using this device is as follows: The PVC flooring can be driven through two sets of pressure rollers 2 by a traction device. The heat transfer oil 9 is heated by a constant temperature box 8. The heat transfer oil 9 in the constant temperature box 8 is drawn into the heat transfer cylinder 7 by a circulating pump 10. Then the PVC flooring can be heated by the heat transfer cylinder 7. The heating range of the pressure rollers 2 can be adjusted by the heat transfer cylinder 7, thereby reducing heat waste and lowering costs.

[0021] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 2 Included with instruction manual Figure 3 The heat-conducting cylinder 7 includes a fixed cylinder 11 fixedly installed in the middle of the circular through hole 6, and movable cylinders 12 are provided on both sides of the fixed cylinder 11. The movable cylinders 12 and the fixed cylinder 11 are connected by multiple oil guide pipes 13.

[0022] The process of adjusting the heating range of the heat-conducting cylinder 7 is as follows: by moving the movable cylinder 12, the distance between the movable cylinder 12 and the fixed cylinder 11 can be changed, thereby adjusting the heating range. The heat-conducting oil 9 can be easily transferred through the oil guide pipe 13, and space is left for the movable cylinder 12 to move.

[0023] Refer to the instruction manual appendix Figure 1 Included with instruction manual Figure 2 A sealed bearing 14 is installed on the outer surface of the movable cylinder 12. An oil inlet pipe 15 is installed at the outlet end of the circulating pump 10. One end of the oil inlet pipe 15 extends into one sealed bearing 14, and a return oil pipe 16 is installed in the other sealed bearing 14. The outlet end of the return oil pipe 16 extends into the constant temperature chamber 8. The part of the oil inlet pipe 15 and the return oil pipe 16 inside the sealed bearing 14 is a rigid pipe, and the part outside the sealed bearing 14 is a flexible pipe. Two circulating pumps 10 are installed on each constant temperature chamber 8. Each circulating pump 10 can make the heat transfer oil 9 flow in the corresponding heat transfer cylinder 7 and constant temperature chamber 8.

[0024] The process of circulating pump 10 driving the flow of heat transfer oil 9 is as follows: When the circulating pump 10 is started, the heat transfer oil 9 in the constant temperature box 8 can be drawn out, and then the heat transfer oil 9 enters the moving cylinder 12 through the oil inlet pipe 15. After passing through the heat transfer pipe 13, the heat transfer oil 9 enters another moving cylinder 12 through the fixed cylinder 11. Finally, it returns to the constant temperature box 8 through the oil return pipe 16, realizing the circulation of heat transfer oil 9. The sealed bearing 14 facilitates the rotation of the moving cylinder 12 with the pressure roller 2.

[0025] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 2 Instruction manual attached Figure 3 Included with instruction manual Figure 4Multiple heat-conducting grooves 17 are provided inside the circular through hole 6. The heat-conducting grooves 17 are evenly distributed in a circle within the circular through hole 6. The multiple heat-conducting grooves 17 are located on both sides of the fixed cylinder 11. Multiple first heat-conducting pipes 18 are installed at both ends of the fixed cylinder 11. The first heat-conducting pipes 18 extend into the heat-conducting grooves 17. Multiple second heat-conducting pipes 19 are installed on the side surface of the movable cylinder 12 near the fixed cylinder 11. The number of second heat-conducting pipes 19 is the same as the number of first heat-conducting pipes 18. The second heat-conducting pipes 19 are located inside the first heat-conducting pipes 18. The contact area with the pressure roller 2 can be increased through the first heat-conducting pipes 18 and the heat-conducting grooves 17, which facilitates the heating of the pressure roller 2.

[0026] Refer to the instruction manual appendix Figure 1 Included with instruction manual Figure 3 The oil guide pipe 13 is a flexible pipe. The flexible pipe is located between the second heat guide pipe 19 and the first heat guide pipe 18 and connects the second heat guide pipe 19 and the first heat guide pipe 18 at the corresponding positions, so as to facilitate the flow of heat transfer oil 9 between the first heat guide pipe 18 and the second heat guide pipe 19.

[0027] Refer to the instruction manual appendix Figure 1 Included with instruction manual Figure 2 The pressure roller 2 is fitted with movable heat insulation sleeves 20 at both ends, which can prevent the pressure roller 2 from leaking heat.
