Description

Technical Field

[0001] This utility model relates to the technical field of sealing strip calendering device, and in particular to sealing strip calendering mechanism. Background Technology

[0002] The raw material for the sealing strip is placed in a heating device for preheating treatment to reach the appropriate temperature and viscosity. The softened material is then fed into the inlet of a calender. When the material enters the gap between two rollers, it is squeezed into thin sheets or strips of a specific shape under the pressure of the rollers, thus forming the sealing strip.

[0003] Common sealing strip calendering mechanisms generate exhaust gas during operation, which needs to be discharged through an exhaust pipe. The filter element inside the exhaust pipe needs to be replaced. Replacing the filter element requires disassembling multiple screws or other fasteners, which is not only time-consuming but also prone to screw loss or damage. In addition, operators must use various tools to complete the disassembly and reinstallation, increasing the difficulty of operation and time costs.

[0004] Therefore, to address the issue that the aforementioned sealing strip calendering mechanism generates exhaust gas during operation, which needs to be discharged through an exhaust pipe, and that replacing the filter element is rather cumbersome, a sealing strip calendering mechanism can be designed. When the filter element needs to be replaced, turning the knob moves the moving plate along the screw, thereby moving the sealing semi-circular ring and the mounting ring. This moves the mounting ring from inside the exhaust pipe to the outside, facilitating the removal of the old filter element and the installation of the new one. No screws or other fasteners need to be removed, allowing workers to quickly replace the filter element, reducing downtime and solving the aforementioned problems. Utility Model Content

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-4This utility model provides an embodiment of a sealing strip calendering mechanism, including a base 1; it also includes a waste gas discharge pipe 5, a screw 7, a notch 8, a movable plate 10, a sealing semicircular ring 12, and a mounting ring 13. Two support plates 2 are welded to the upper surface of the base 1, and a fixed platform 3 is fixedly connected to the upper end of the two support plates 2. A heating box 4 is fixedly connected to the upper end of the fixed platform 3, and a waste gas discharge pipe 5 is fixedly connected to the upper end of the heating box 4. A notch 8 is provided on the surface of the waste gas discharge pipe 5, and a fixed platform 8 is welded to the upper surface of the heating box 4. Fixed plate 6, one end of screw 7 is rotatably connected to the right end of fixed plate 6, and knob 9 is fixedly connected to the other end of screw 7. Moving plate 10 is threadedly connected to the surface of screw 7. Slide rod 11 is fixedly connected to the right end of fixed plate 6. Moving plate 10 is slidably connected to the surface of slide rod 11. Sealing semi-circular ring 12 is fixedly connected to the left end of moving plate 10. Sealing semi-circular ring 12 has the same specifications as notch 8. Installation ring 13 is installed on the left end of sealing semi-circular ring 12. Filter element is installed inside installation ring 13.

[0023] Please see Figures 1-3 In this embodiment, a heating plate 17 is installed on the inner surface of the heating chamber 4, and a discharge pipe 21 is fixedly connected to the lower end of the heating chamber 4. A solenoid valve 22 is installed on the surface of the discharge pipe 21. The heating plate 17 is responsible for providing a uniform heat distribution to the raw materials entering the heating chamber 4, so that they reach an appropriate softness for subsequent calendering operations. The discharge pipe 21 is used to discharge the heat-treated material from the heating chamber 4 and guide it to the calendering mechanism. A motor 14 is installed on the upper surface of the heating chamber 4, and a connecting plate 15 is fixedly connected to the output end of the motor 14. A stirring rod 16 is fixedly connected to the lower surface of the connecting plate 15. When the motor 14 is started, the connecting plate 15 can be rotated, thereby driving the stirring rod 16 to perform stirring. A motor 23 is installed on the rear surface of the support plate 2. A drive gear 27 is fixedly connected to the output end of the motor 23. A squeeze roller 26 is fixedly connected to the side surface of the drive gear 27 away from the motor 23. There are two squeeze rollers 26. When the motor 23 is started, the drive gear 27 is rotated, thereby driving the squeeze roller 26 to rotate.

[0024] Please see Figures 1-3In this embodiment, a driven gear 25 is rotatably connected to the inner side of the rear support plate 2. The driven gear 25 is meshed with the driving gear 27. Another extrusion roller 26 is fixedly connected to the side surface of the driven gear 25 away from the motor 23. The driving gear 27 drives the driven gear 25, which in turn drives the other extrusion roller 26 to rotate. A narrow channel is formed between the two extrusion rollers 26. When the soft material after heat treatment passes through this channel, it will be uniformly extruded into the required shape and thickness. A cooling box 24 is installed between the two support plates 2. The cooling box 24 is located directly below the two extrusion rollers 26. The cooling box 24 is used to quickly cool the extruded sealing strip so that it can harden rapidly and maintain the required shape. This helps prevent the material from deforming due to residual heat, ensuring the quality and dimensional stability of the finished product. A plasticizer storage tank 18 is fixedly connected to the surface of the heating box 4. A pump body 19 is installed on the upper surface of the plasticizer storage tank 18. One end of the delivery pipe 20 is fixedly connected to the output end of the pump body 19. The other end of the delivery pipe 20 is fixedly connected to the upper surface of the heating box 4. A stretching mechanism 28 is installed on the upper surface of the base 1. The plasticizer storage tank 18 is used to store plasticizer, which is an additive used to improve the flexibility of materials, reduce hardness, and improve processing performance. The pump body 19 is responsible for drawing the plasticizer from the storage tank and delivering it to the heating box 4 through the delivery pipe 20. The stretching mechanism 28 is used to further stretch the sealing strip after heating and extrusion to obtain the required length and thickness, which can improve the physical properties of the material, such as increasing elastic recovery and surface smoothness.

[0025] When the filter element needs to be replaced during operation, turn knob 9 to move the moving plate 10 along screw 7, thereby moving the sealing semi-circular ring 12 and mounting ring 13. This moves the mounting ring 13 from inside the exhaust pipe 5 to the outside, facilitating the removal of the old filter element and the installation of the new one. No screws or other fasteners need to be removed, allowing workers to quickly replace the filter element, reducing downtime and improving production efficiency. Heating plate 17 provides a uniform heat distribution to the raw materials entering heating chamber 4, ensuring they reach the appropriate softness for subsequent calendering operations. Discharge pipe 21 discharges the heat-treated material from heating chamber 4. The material is guided to the calendering mechanism. Motor 14 is started, which drives the connecting plate 15 to rotate, thereby driving the stirring rod 16 to stir. Motor 23 is started, which drives the drive gear 27 to rotate, thereby driving the extrusion roller 26 to rotate. The drive gear 27 drives the driven gear 25, which in turn drives another extrusion roller 26 to rotate. A narrow channel is formed between the two extrusion rollers 26. When the soft material after heat treatment passes through this channel, it will be uniformly extruded into the required shape and thickness. Cooling box 24 is used to quickly cool the extruded sealing strip, so that it can harden quickly and maintain the required shape. This helps prevent the material from deforming due to residual heat, ensuring the quality and dimensional stability of the finished product. The plasticizer storage tank 18 is used to store plasticizer, which is an additive used to improve the flexibility of the material, reduce its hardness, and improve its processing performance. The pump body 19 is responsible for drawing the plasticizer from the storage tank and delivering it to the heating chamber 4 through the delivery pipe 20. The stretching mechanism 28 is used to further stretch the sealing strip after heating and extrusion to obtain the required length and thickness, which can improve the physical properties of the material, such as increasing its elastic recovery and surface smoothness.

[0026] Through the above steps, when the filter element needs to be replaced, turn the knob 9 to move the moving plate 10 along the screw 7, thereby moving the sealing semi-circular ring 12 and the mounting ring 13. This moves the mounting ring 13 from inside the exhaust pipe 5 to the outside, making it easy to remove the old filter element and install the new one. There is no need to remove screws or other fasteners. The staff can quickly complete the filter element replacement, reducing downtime and improving production efficiency. This solves the problem that common sealing strip calendering mechanisms generate exhaust gas during operation, which needs to be discharged through the exhaust pipe, while filter element replacement is relatively cumbersome.
