Description

Technical Field

[0001] This utility model relates to the field of coated paper processing technology, and in particular to a cooling device for coated paper casting and composite molding. Background Technology

[0002] Coated paper is made by melting PVC material at high temperature and extruding it into a cast film, then stretching the extruded cast film. Subsequently, the stretched cast film is attached to the surface of paper, cooled and shaped, and then pressed together to form coated paper.

[0003] During the production of coated paper, cooling rollers are used to cool the coated paper. The cooling rollers have cooling water chambers inside. Cooling water flows in from one end of the cooling roller and flows out from the other end, thus maintaining the low temperature of the surface of the cooling roller to cool the coated paper. However, after long-term use, a large amount of scale will form on the inner wall of the water chamber inside the cooling roller, causing the inner wall of the cooling roller to thicken, thereby affecting the cooling efficiency of the cooling roller. Utility Model Content

[0004] To address the aforementioned problems, this invention provides a cooling device for coated paper casting composite molding.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a cooling device for casting composite molding of coated paper, comprising a hollow cooling roller, an inlet through which a water inlet is formed on the side wall of the cooling roller, an outlet through which a water inlet is formed on the side wall of the cooling roller away from the water inlet, an inlet connector installed in the inlet, and an outlet connector installed in the outlet. Both the inlet connector and the outlet connector are rotary connectors, and the inlet connector and the outlet connector are rotatably connected to the inlet and the outlet, respectively. A cleaning component for cleaning the inner wall of the cooling roller is provided inside the cooling roller.

[0006] By adopting the above technical solution, when workers need to cool the coated paper, they must bring the surface of the coated paper into contact with the outer wall of the cooling roller. Then, the workers must pull the coated paper, moving it along the outer wall of the cooling roller. During this process, water pipes are connected through the inlet and outlet connectors, allowing water to flow into the cooling roller from the inlet connector, thus carrying away the heat from the coated paper. The water is then discharged from the cooling roller through the outlet connector. During this process, the workers must rotate the cooling roller to ensure that the heat from the coated paper is carried away evenly. While the cooling roller is rotating, the cleaning component cleans the inner wall of the cooling roller, thereby reducing the probability of decreased cooling efficiency due to excessive scale buildup on the inner wall.

[0007] Furthermore, the cleaning assembly includes a connecting pipe fixed to the water inlet connector, a support rod fixedly mounted on the side wall of the connecting pipe away from the water inlet connector, a support plate sleeved on the outer wall of the support rod, and multiple scrapers fixedly mounted on the side wall of the support plate away from the connecting pipe. The side wall of the scraper abuts against the inner wall of the cooling roller. Multiple water spray holes are opened through the side wall of the connecting pipe. The outer wall of the support plate abuts against the inner wall of the cooling roller.

[0008] By adopting the above technical solution, when the cooling roller rotates, the water inlet connector rotates relative to the cooling roller, which in turn causes the connecting pipe and support rod to rotate relative to the cooling roller under the action of the water inlet connector. This, in turn, causes the support plate to rotate relative to the cooling roller. During this process, the scraper cleans the inner wall of the cooling roller, thus reducing the probability of decreased cooling efficiency due to excessive scale buildup on the inner wall of the cooling roller. Furthermore, since the connecting pipe, support rod, and water inlet connector are fixed together, water flows into the cooling roller through the spray holes.

[0009] Furthermore, an installation cylinder is fixedly installed on the side wall of the support plate, and a flow guide is fixedly installed on the side wall of the installation cylinder away from the support plate. The end of the flow guide away from the installation cylinder passes through the water outlet connector and extends beyond the water outlet connector. The installation cylinder and the scraper are fixed to each other.

[0010] Furthermore, a water spray pipe is uniformly installed in each of the multiple water spray holes, and the end of the water spray pipe away from the connecting pipe passes through the support plate and extends to the space between the mounting cylinder and the inner wall of the cooling roller.

[0011] By adopting the above technical solution, water flows into the cooling roller of the support plate through the spray pipe. During this process, the water flows along the surface of the mounting cylinder and the guide component into the water outlet and then out of the cooling roller. In this process, the mounting cylinder and the guide component reduce the difficulty of water flowing out of the cooling roller. In addition, the mounting cylinder and the guide component also prevent water from accumulating in most of the space inside the cooling roller, thereby reducing the probability of a large amount of water inside the cooling roller, thus reducing the energy required to rotate the cooling roller, and thus reducing production costs.

[0012] Furthermore, a water outlet pipe is installed at the end of the water outlet connector away from the cooling roller, and a filter screen is fixedly installed on the inner wall of the water outlet pipe.

[0013] Furthermore, a waste pipe is connected to the outer wall of the water outlet pipe, and the waste pipe is inclinedly arranged at the lower end of the water outlet pipe.

[0014] By adopting the above technical solution, the filter screen filters out the scale, and the filtered scale enters the waste pipe. In this process, the difficulty for staff to collect the scale is reduced, thereby reducing the difficulty of the staff's work.

[0015] Furthermore, the end of the waste pipe furthest from the outlet pipe is threaded with a sealing cap.

[0016] By adopting the above technical solution, the sealing cover reduces the difficulty for workers to clean the scale inside the waste pipe, thereby reducing the difficulty of their work.

[0017] Furthermore, the water spray pipe, connecting pipe, and support plate are fixed together by welding.

[0018] By adopting the above technical solution, the water spray pipe, connecting pipe, and support plate are fixed to each other by welding, which improves the sealing performance of the device and reduces the probability of leakage at both ends of the water spray pipe.

[0019] In summary, this utility model has the following beneficial effects:

[0020] 1. In this application, when the operator needs to cool the coated paper, the operator must bring the surface of the coated paper into contact with the outer wall of the cooling roller. Then, the operator must pull the coated paper, causing it to move along the outer wall of the cooling roller. During this process, the operator must connect water pipes through the inlet and outlet connectors, allowing water to flow into the cooling roller from the inlet connector, thus carrying away the heat from the coated paper. Subsequently, the water is discharged from the cooling roller through the outlet connector. During this process, the operator must rotate the cooling roller to ensure that the heat from the coated paper is carried away evenly. During the rotation of the cooling roller, the cleaning component cleans the inner wall of the cooling roller, thereby reducing the probability of decreased cooling efficiency due to excessive scale buildup on the inner wall of the cooling roller.

[0021] 2. In this application, when the cooling roller rotates, the water inlet connector rotates relative to the cooling roller, which in turn causes the connecting pipe and support rod to rotate relative to the cooling roller under the action of the water inlet connector. This, in turn, causes the support plate to rotate relative to the cooling roller. During this process, the scraper cleans the inner wall of the cooling roller, thus reducing the probability of decreased cooling efficiency due to excessive scale buildup on the inner wall of the cooling roller. Furthermore, since the connecting pipe, support rod, and water inlet connector are fixed together, water flows into the cooling roller through the spray nozzles.

[0022] 3. In this application, water flows into the cooling roller of the support plate through a spray pipe. During this process, the water flows along the surface of the mounting cylinder and the guide component into the water outlet and then out of the cooling roller. In this process, the mounting cylinder and the guide component reduce the difficulty of water flowing out of the cooling roller. In addition, the mounting cylinder and the guide component also prevent water from accumulating in most of the space inside the cooling roller, thereby reducing the probability of a large amount of water inside the cooling roller, thus reducing the energy required to rotate the cooling roller, and thus reducing production costs.

[0027] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0028] like Figure 1-3 As shown in the figure, this application discloses a cooling device for film-coated paper casting composite molding, including a cooling roller 1, a water inlet connector 13, a water outlet connector 14, a cleaning component 2, a mounting cylinder 3, a guide component 31, and a water spray pipe 4. The cooling roller 1 is a hollow cylindrical structure with a horizontal axis. A water inlet 11 is provided through the side wall of the cooling roller 1, and a water outlet 12 is provided through the side wall of the cooling roller 1 away from the water inlet 11. The water inlet connector 13 is installed inside the water inlet 11, and the water outlet connector 14 is installed inside the water outlet 12. Both the water inlet connector 13 and the water outlet connector 14 are rotary connectors, and the water inlet connector 13 and the water outlet connector are rotatably connected to the water inlet 11 and the water outlet 12, respectively.

[0029] When the coated paper needs to be cooled, the worker must bring the surface of the coated paper into contact with the outer wall of the cooling roller 1. Then, the worker must pull the coated paper, moving it along the outer wall of the cooling roller 1. During this process, the worker must connect water pipes through the inlet connector 13 and the outlet connector 14, allowing water to flow into the cooling roller 1 from the inlet connector 13, thus carrying away the heat from the coated paper. The water then exits the cooling roller 1 through the outlet connector 14. During this process, the worker must rotate the cooling roller 1 to ensure that the heat from the coated paper is carried away evenly. While the cooling roller 1 is rotating, the cleaning component 2 cleans the inner wall of the cooling roller 1, thereby reducing the probability of decreased cooling efficiency due to excessive scale buildup on the inner wall.

[0030] The cleaning assembly 2 is installed inside the cooling roller 1 and is used to clean the inner wall of the cooling roller 1. The cleaning assembly 2 includes a connecting pipe 21, a support rod 22, a support plate 23, and scrapers 24. The connecting pipe 21 is a cylindrical structure with its axis coinciding with the axis of the cooling roller 1. The connecting pipe 21 is fixed to the water inlet connector 13, and multiple water spray holes 25 are provided through the side wall of the connecting pipe 21. The support rod 22 is a cylindrical structure with its axis coinciding with the axis of the cooling roller 1. The support rod 22 is fixedly installed on the side wall of the connecting pipe 21 away from the water inlet connector 13. The support plate 23 is sleeved on the outer wall of the support rod 22, with its axis coinciding with the axis of the cooling roller 1. The outer wall of the support plate 23 abuts against the inner wall of the cooling roller 1. Multiple scrapers 24 are provided and fixedly installed on the side wall of the support plate 23 away from the connecting pipe 21. The side wall of the scraper 24 abuts against the inner wall of the cooling roller 1.

[0031] When the cooling roller 1 rotates, the water inlet connector 13 rotates relative to the cooling roller 1, which in turn causes the connecting pipe 21 and the support rod 22 to rotate relative to the cooling roller 1 under the action of the water inlet connector 13. This causes the support plate 23 to rotate relative to the cooling roller 1. During this process, the scraper 24 cleans the inner wall of the cooling roller 1, thus reducing the probability of decreased cooling efficiency due to excessive scale buildup on the inner wall of the cooling roller 1. Furthermore, since the connecting pipe 21, the support rod 22, and the water inlet connector 13 are fixed together, water flows into the cooling roller 1 through the spray hole 25.

[0032] The mounting cylinder 3 is fixedly mounted on the side wall of the support plate 23, with its axis coinciding with the axis of the support plate 23. The mounting cylinder 3 and the scraper 24 are fixed to each other. The guide member 31 is fixedly mounted on the side wall of the mounting cylinder 3 away from the support plate 23. The end of the guide member 31 away from the mounting cylinder 3 passes through the water outlet connector 14 and extends beyond the water outlet connector 14.

[0033] The water spray pipe 4 is provided with multiple water spray holes 25 respectively. The end of the water spray pipe 4 away from the connecting pipe 21 passes through the support plate 23 and extends to the inner wall between the mounting cylinder 3 and the cooling roller 1.

[0034] Water flows through the spray pipe 4 into the cooling roller 1 of the support plate 23. During this process, the water flows along the surface of the mounting cylinder 3 and the guide component 31 into the water outlet 14 and then out of the cooling roller 1. In this process, the mounting cylinder 3 and the guide component 31 reduce the difficulty of water flowing out of the cooling roller 1. In addition, the mounting cylinder 3 and the guide component 31 also prevent water from accumulating in most of the space inside the cooling roller 1, thereby reducing the probability of a large amount of water inside the cooling roller 1, thus reducing the energy required to rotate the cooling roller 1 and reducing production costs.

[0035] To reduce the workload for workers, a water outlet pipe 5 is installed at the end of the water outlet connector 14 furthest from the cooling roller 1. A filter screen 51 is fixedly installed on the inner wall of the water outlet pipe 5, and a waste pipe 6 is connected to the outer wall of the water outlet pipe 5. The waste pipe 6 is inclined and installed at the lower end of the water outlet pipe 5. The filter screen 51 filters out scale, and the filtered scale enters the waste pipe 6. This process reduces the difficulty for workers to collect scale, thereby reducing the workload for workers.

[0036] To reduce the workload for workers, a sealing cap 7 is threaded onto the end of the waste pipe 6 furthest from the outlet pipe 5. The sealing cap 7 reduces the difficulty for workers to clean scale inside the waste pipe 6, thereby reducing the workload for workers.

[0037] To reduce the probability of leakage at both ends of the water spray pipe 4, the water spray pipe 4 is fixed to the connecting pipe 21 and the support plate 23 by welding. This welding fixation improves the sealing of the device, thereby reducing the probability of leakage at both ends of the water spray pipe 4.

[0038] The operating principle of the cooling device for cast film composite molding in this embodiment is as follows: When the operator needs to cool the cast film, the operator needs to bring the surface of the cast film into contact with the outer wall of the cooling roller 1. Then, the operator needs to pull the cast film, causing it to move along the outer wall of the cooling roller 1. During this process, the operator needs to connect a water pipe through the inlet connector 13 and the outlet connector 14, allowing water to flow from the inlet connector 13 into the cooling roller 1, thus carrying away the heat from the cast film. Subsequently, the water is discharged from the cooling roller 1 through the outlet connector 14. During this process, the operator needs to rotate the cooling roller 1, ensuring that the cooling roller 1 evenly carries away the heat from the cast film. During the rotation of the cooling roller 1, the cleaning component 2 cleans the inner wall of the cooling roller 1, thereby reducing the probability of decreased cooling efficiency due to excessive scale buildup on the inner wall of the cooling roller 1.

[0039] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
