Description

Technical Field

[0001] This utility model relates to the field of PVC flooring production, specifically a drying structure for a PVC flooring extruder. Background Technology

[0002] The production process of PVC flooring mainly includes raw material preparation, mixing, extrusion, embossing, constant temperature hot pressing, cutting, and packaging. After extrusion molding, PVC flooring needs to undergo drying treatment to ensure that the flooring surface is dried evenly and to avoid problems in subsequent processing.

[0003] Existing PVC flooring extruders with drying structures are equipped with conveyor belts. When drying PVC flooring, the PVC flooring needs to be placed on the conveyor belt and transported to the drying chamber for drying. However, because the conveyor belt is in contact with the bottom of the PVC flooring, it is difficult for the bottom of the PVC flooring to make sufficient contact with the hot air, which makes it difficult to dry the bottom of the PVC flooring quickly and reduces the overall drying effect of the PVC flooring. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a drying structure for a PVC flooring extruder to solve the technical problem of poor drying effect on the bottom of PVC flooring.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a drying structure for a PVC flooring extruder, comprising a frame, an air guide chamber, and a conveyor belt. A drying hood is installed on the top of the frame, an air supply pipe is installed on the back of the frame, an air guide pipe extending into the air supply pipe is installed on the back of the drying hood, and multiple air jet pipes extending into the frame are installed on the air supply pipe. Multiple heat-conducting blocks are installed on the top of the conveyor belt, and a first vent hole is opened on the top of the heat-conducting blocks, and a second vent hole is provided on the outer wall of the heat-conducting blocks. Material inlets are opened on both sides of the drying hood.

[0006] By adopting the above technical solution, the material inlet is designed to allow PVC flooring to enter the drying hood, thus facilitating subsequent drying of the PVC flooring.

[0007] Furthermore, a drive motor is installed on one side of the outer surface of the frame, the output end of the drive motor is connected to a drive roller, a driven roller is provided inside the frame, and a conveyor belt is sleeved between the driven roller and the drive roller.

[0008] By adopting the above technical solution, when PVC flooring needs to be conveyed, the drive motor can be started. The operation of the drive motor can drive the active roller to rotate, which in turn drives the conveyor belt to rotate, so as to convey the PVC flooring.

[0009] Furthermore, the drying hood is equipped with two air supply pipes, and a branch pipe is connected between the two air supply pipes.

[0010] By adopting the above technical solution, hot gas can enter the inside of the distribution pipe through the gas transmission pipe and flow inside the distribution pipe.

[0011] Furthermore, a plurality of jet nozzles are installed at the bottom of the diversion pipe, and the jet nozzles are located above the conveyor belt.

[0012] By adopting the above technical solution, hot air can flow into the nozzle through the diversion pipe and then be ejected through the nozzle, thereby achieving the purpose of drying PVC flooring.

[0013] Furthermore, two hot air blowers are installed on the top of the drying hood. The air inlet of the hot air blower is connected to an exhaust pipe, and the air outlet of the hot air blower is connected to an exhaust pipe that extends into the air supply pipe.

[0014] By adopting the above technical solution, when PVC flooring needs to be dried, a hot air blower can be started. The hot air blower can draw in external air, which, after being heated, will enter the air outlet pipe and then enter the air supply pipe.

[0015] Furthermore, the air inlet end of the air guide tube extends into the interior of the air supply pipe, and multiple jet pipes are equidistantly distributed on the air supply pipe.

[0016] By adopting the above technical solution, some hot gas can enter the gas guide pipe through the gas transmission pipe, and then enter the gas supply pipe through the gas guide pipe.

[0017] Furthermore, the frame is internally equipped with multiple support rollers that rotate and contact the conveyor belt.

[0018] By adopting the above technical solution, the support roller can play the role of supporting the conveyor belt.

[0019] Furthermore, multiple heat-conducting blocks are equidistantly distributed on the conveyor belt, and the air-conducting cavity is connected to the first vent and the second vent, respectively.

[0020] By adopting the above technical solution, some of the hot air entering the air guide cavity will enter the first vent and come into contact with the bottom of the PVC floor, thereby improving the drying effect on the PVC floor.

[0021] Furthermore, the jet pipe is located on the back of the heat-conducting block, and the bottom of the jet pipe is lower than the bottom of the heat-conducting block.

[0022] By adopting the above technical solution, the hot air can flow to the bottom of the PVC floor when it is ejected, thus facilitating the drying process of the bottom of the PVC floor.

[0023] Furthermore, a control panel is mounted on the outer surface of the frame, and the control panel is electrically connected to the drive motor and the hot air blower respectively.

[0024] By adopting the above technical solution, it is convenient to start or stop the drive motor and hot air blower through the control panel.

[0025] In summary, the present invention has the following main advantages:

[0026] 1. This utility model incorporates a heat-conducting block, allowing the PVC flooring to be placed on it, thus preventing the bottom of the PVC flooring from directly contacting the conveyor belt. This facilitates the drying of the bottom of the PVC flooring. Furthermore, by incorporating an air guide pipe, an air supply pipe, and an air jet pipe, some hot air enters the air guide pipe through the air supply pipe, then enters the air supply pipe, and is finally ejected through the air jet pipe. As the hot air is ejected, it flows towards the bottom of the PVC flooring, thereby facilitating the drying of the bottom of the PVC flooring and improving the drying efficiency of the bottom of the PVC flooring. This prevents the bottom of the PVC flooring from directly contacting the conveyor belt and becoming difficult to dry.

[0027] 2. This utility model has an air guide cavity, a first vent hole, and a second vent hole. Some hot air will enter the air guide cavity, and the hot air will come into contact with the bottom of the PVC floor through the first vent hole, which facilitates the drying of the part of the PVC floor that is in contact with the heat-conducting block, thereby improving the drying efficiency of the PVC floor.

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0036] The embodiments of this utility model will be described below based on its overall structure. Example 1:

[0037] A drying structure for a PVC flooring extruder, such as Figures 1-6 As shown, the system includes a frame 1, an air duct 19, and a conveyor belt 4. A drying hood 7 is installed on the top of the frame 1, and an air supply pipe 16 is installed on the back of the frame 1. An air duct 15 extending into the air supply pipe 16 is installed on the back of the drying hood 7. Multiple air jet pipes 18 extending into the interior of the frame 1 are installed on the air supply pipe 16. Multiple heat-conducting blocks 17 are installed on the top of the conveyor belt 4, and a first vent 20 is opened on the top of the heat-conducting block 17. A second vent 21 is provided on the outer wall of the heat-conducting block 17. Material inlets 8 are opened on both sides of the drying hood 7. The material inlets 8 allow PVC flooring to enter the interior of the drying hood 7, thereby facilitating the subsequent drying process of the PVC flooring.

[0038] Specifically, multiple heat-conducting blocks 17 are equidistantly distributed on the conveyor belt 4. The air-conducting chamber 19 is connected to the first vent 20 and the second vent 21 respectively. Some of the hot air entering the air-conducting chamber 19 will enter the first vent 20 and contact the bottom of the PVC floor, improving the drying effect on the PVC floor. The jet pipe 18 is located on the back of the heat-conducting block 17. The bottom height of the jet pipe 18 is lower than the bottom height of the heat-conducting block 17 so that the hot air can flow to the bottom of the PVC floor when it is sprayed out, thereby facilitating the drying treatment of the bottom of the PVC floor.

[0039] See Figures 2-6A drive motor 2 is installed on one side of the outer surface of the frame 1. The output end of the drive motor 2 is connected to the drive roller 3. The driven roller 5 is installed inside the frame 1, and a conveyor belt 4 is sleeved between the driven roller 5 and the drive roller 3. When it is necessary to convey PVC flooring, the drive motor 2 can be started. The operation of the drive motor 2 can drive the drive roller 3 to rotate, thereby driving the conveyor belt 4 to rotate, so as to convey PVC flooring. Two air supply pipes 14 are installed inside the drying hood 7, and a diversion pipe 12 is connected between the two air supply pipes 14 so that hot air can enter the interior of the diversion pipe 12 through the air supply pipes 14 and flow inside the diversion pipe 12. Multiple air nozzles 13 are installed at the bottom of the diversion pipe 12. The air nozzles 13 are located above the conveyor belt 4. Hot air can flow into the interior of the air nozzles 13 through the diversion pipe 12 and then be sprayed out through the air nozzles 13, thereby achieving the purpose of drying PVC flooring.

[0040] See Figures 1-4 Two hot air blowers 9 are installed on the top of the drying hood 7. The air inlet end of the hot air blower 9 is connected to the air extraction pipe 10, and the air outlet end of the hot air blower 9 is connected to the air outlet pipe 11 extending into the air supply pipe 14. When the PVC floor needs to be dried, the hot air blower 9 can be started. The hot air blower 9 can draw in the outside air, which will be heated and enter the air outlet pipe 11, and then enter the air supply pipe 14. The air inlet end of the air guide pipe 15 extends into the air supply pipe 14. Multiple jet pipes 18 are evenly distributed on the air supply pipe 16, which can allow some hot air to enter the air guide pipe 15 through the air supply pipe 14, and then enter the air supply pipe 16 through the air guide pipe 15. The outer surface of the frame 1 is equipped with a control panel 6. The control panel 6 is electrically connected to the drive motor 2 and the hot air blower 9 respectively, which makes it convenient to start or stop the drive motor 2 and the hot air blower 9 through the control panel 6. Example 2:

[0041] Based on the above embodiment 1, since the conveyor belt 4 will bear a large pressure when conveying PVC flooring, the following structure will be set up to facilitate the support of the conveyor belt 4 and share the pressure.

[0042] See Figure 2 The frame 1 has multiple support rollers 22 inside, and the support rollers 22 are in contact with the conveyor belt 4. The support rollers 22 can support the conveyor belt 4 and share the pressure, thereby improving the service life of the conveyor belt 4.

[0043] The working principle of this utility model is as follows: First, before using the device, the power supply can be turned on. During use, the PVC flooring is placed on top of the heat-conducting block 17 on the conveyor belt 4. Then, the drive motor 2 is started. The drive motor 2 drives the active roller 3 to rotate, which in turn drives the conveyor belt 4 to rotate. The conveyor belt 4 then transports the PVC flooring. After the PVC flooring enters the drying hood 7 through the feed inlet 8, the hot air fan 9 can be started. Hot air enters the air delivery pipe 14 through the air outlet 11. The hot air can then flow into the air nozzle 13 through the diversion pipe 12. The hot air is sprayed out through the nozzle 13 to dry the top of the PVC flooring. Some of the hot air enters the air guide pipe 15 through the air supply pipe 14, and then enters the air supply pipe 16 through the air guide pipe 15. It is then sprayed out through the nozzle 18 to dry the bottom of the PVC flooring. The hot air can also enter the air guide chamber 19 through the second vent 21. Some of the hot air comes into contact with the bottom of the PVC flooring through the first vent 20, which can improve the drying effect on the bottom of the PVC flooring. After the PVC flooring is dried, it can be removed from the drying hood 7.
