Description

Technical Field

[0001] This utility model belongs to the field of waterproof membrane production technology, specifically relating to a waterproof membrane base drying and processing equipment. Background Technology

[0002] Waterproof membrane is a commonly used waterproofing material in construction and civil engineering. It typically consists of multiple layers, with the base layer being the material that serves as the foundation and support layer. During the production of waterproof membranes, the base layer usually undergoes a series of processing steps, including coating and adhesion of the waterproofing layer. To ensure the quality and stability of the waterproof membrane, the base material needs to be dried to remove excess moisture and improve its physical properties.

[0003] A Chinese patent discloses a base drying device for waterproof membrane production (authorization announcement number CN219841760U). This patented technology can use a striking roller to strike the base during the conveying process and combine it with heated air for drying. The drying speed is relatively fast, and the base can be dried continuously and quickly.

[0004] However, most existing methods for drying waterproof membrane substrates rely solely on air drying, resulting in poor drying efficiency and affecting the overall drying effect. For example, the aforementioned comparative document only uses air drying to dry the waterproof membrane substrate. Therefore, those skilled in the art have provided a waterproof membrane substrate drying and processing equipment to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to provide a drying and processing equipment for waterproof membrane base materials, which can solve the problems mentioned in the background art.

[0006] The specific technical solution adopted in this utility model is as follows:

A first guide roller is also provided inside the drying box near the inlet and outlet, and a second guide roller is provided inside the drying box below the first guide roller. A second heating roller is provided inside the drying box on one side of the second guide roller. An electric lifting rod is also installed on the upper surface of the drying box. The lower end of the electric lifting rod is connected to a lifting frame inside the drying box. The first heating roller is provided inside the lifting frame.

[0008] A heating chamber is installed on the lower surface of the drying oven. An air inlet is provided on the outer side of the heating chamber, and a first exhaust pipe is symmetrically arranged on the front surface of the heating chamber. A branch pipe is connected to the rear end of the first exhaust pipe, and an exhaust hole is provided on the outer side of the branch pipe. Heating pipes are symmetrically arranged inside the heating chamber, and an exhaust fan is installed above the heating pipes inside the heating chamber.

[0024] To make the purpose and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific implementations of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0025] like Figures 1-5 As shown, a waterproof membrane base drying and processing equipment includes a drying chamber 1 and an inlet 12 and an outlet 11 opened from left to right on both sides of the drying chamber 1. A first guide roller 13 is also provided inside the drying chamber 1 near the outlet 11 and the inlet 12. A second guide roller 14 is provided inside the drying chamber 1 below the first guide roller 13. A second heating roller 34 is provided inside the drying chamber 1 on one side of the second guide roller 14. An electric lifting rod 3 is also installed on the upper surface of the drying chamber 1. The lower end of the electric lifting rod 3 is connected to a lifting frame 32 inside the drying chamber 1. A first heating roller 33 is provided inside the lifting frame 32. This arrangement uses the first heating roller 33 and the second heating roller 34 to conduct heat to the waterproof membrane base passing through, thereby improving its drying effect.

[0026] A heating chamber 2 is installed on the lower surface of the drying chamber 1. An air inlet 21 is provided on the outside of the heating chamber 2, and a first exhaust pipe 22 is symmetrically arranged on the front surface of the heating chamber 2. The rear end of the first exhaust pipe 22 is connected to a branch pipe 23. An exhaust port 231 is provided on the outside of the branch pipe 23. Heating pipes 24 are symmetrically arranged inside the heating chamber 2, and an exhaust fan 25 is installed above the heating pipes 24 inside the heating chamber 2. This arrangement uses the heating pipes 24 inside the heating chamber 2 to heat the air when the outside air enters, so that the air can be heated and then exhausted through the exhaust port 231 on the outside of the branch pipe 23 to dry the waterproof membrane base.

[0027] like Figure 4 and Figure 5 As shown, guide rods 31 are symmetrically arranged on the upper surface of the lifting frame 32. The upper end of the guide rod 31 penetrates the upper surface of the drying box 1. The fixed end of the electric lifting rod 3 is installed on the upper surface of the drying box 1, and the telescopic end of the electric lifting rod 3 is connected to the upper surface of the lifting frame 32. This arrangement allows the lifting frame 32 to rise and fall inside the drying box 1 by the operation of the electric lifting rod 3. During the rise and fall, the distance between the first heating roller 33 and the second heating roller 34 can be adjusted, thereby satisfying the purpose of drying waterproof membrane base of different thicknesses.

[0028] like Figure 5 As shown, the centers of the second guide roller 14 and the second heating roller 34 are set on the same horizontal line. The first heating roller 33 and the second heating roller 34 are equipped with resistance wires. This arrangement utilizes the resistance wires inside the first heating roller 33 and the second heating roller 34 to generate heat, thereby drying the waterproof membrane base material that passes through.

[0029] like Figure 2 and Figure 3 As shown, the branch pipe 23 is U-shaped, and the first exhaust pipe 22 in front of the heating box 2 is also U-shaped. This arrangement allows hot air to be introduced into the branch pipe 23 through the first exhaust pipe 22, and finally the waterproof membrane base passing through the branch pipe 23 is dried.

[0030] like Figure 3 As shown, the heating tube 24 is an electric heating tube, and at least two sets of heating tubes 24 are provided inside the heating box 2. This arrangement utilizes the two sets of heating tubes 24 inside the heating box 2 to heat the incoming air, so as to facilitate the subsequent drying of the waterproof membrane base.

[0031] The working principle of this utility model is as follows: When using the waterproof membrane base drying and processing equipment, the unwinding mechanism first guides the waterproof membrane base into the drying chamber 1 through the feed inlet 12. After entering, it passes sequentially through the first guide roller 13 and the second guide roller 14, then between one set of first heating rollers 33 and second heating rollers 34. After passing through these rollers, it passes through two sets of pipes 23, then between another set of first heating rollers 33 and second heating rollers 34, and finally through another set of second guide rollers 14 and first guide rollers 13, and is discharged outward through the discharge outlet 11. While the waterproof membrane base is passing between the first heating rollers 33 and second heating rollers 34, the thickness of the waterproof membrane base is first adjusted according to its thickness. The distance between the first heating roller 33 and the second heating roller 34 can be adjusted by activating the electric lifting rod 3 to raise and lower the lifting frame 32, and by guiding it through the guide rod 31. This allows for adjustment of the distance between the first heating roller 33 and the second heating roller 34, accommodating the drying of waterproof membrane bases of different thicknesses. Simultaneously, the exhaust fan 25 inside the heating chamber 2 draws in external air during the drying process, which is then heated by the heating pipe 24. The heated air then enters the branch pipe 23 through the first exhaust pipe 22 and is finally discharged outward through the exhaust hole 231, achieving the purpose of drying both sides of the waterproof membrane base inside the drying chamber 1. This method is highly practical.

[0032] All electrical devices used in this invention are existing and known, and are connected to external controllers and power supplies. They can all be purchased and used directly on the market. Their structures, circuits, and control principles are all existing and known technologies. Therefore, the structure, circuits, and control principles of the device will not be described in detail here.

[0033] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
