Description

Technical Field

[0001] This utility model relates to the field of waterproof membrane preparation technology, and in particular to a drying and preheating device for waterproof membrane production. Background Technology

[0002] Waterproof membrane is a flexible building material that can be rolled up to resist external rainwater and groundwater seepage. It is used in various places and environments, such as building walls and roofs. As a leak-proof connection between the foundation and the building, the waterproof membrane is the first line of defense for waterproofing the entire project and plays a vital role in the overall project.

[0003] Waterproof membranes require drying during the production process to remove moisture. Excessive moisture directly affects the quality of the membrane. For example, if the waterproof membrane base containing moisture enters the prepreg and coating tanks, it will generate a large amount of foam due to moisture evaporation, causing overflow.

[0004] However, existing drying components typically use a drying roller installed on the production equipment to heat and dry the waterproof membrane. The drying effect is relatively average, and the production efficiency is severely limited by the drying roller. Utility Model Content

[0005] The purpose of this invention is to provide a drying and preheating device for the production of waterproof membrane rolls. This invention has the advantages of relatively better drying effect and relatively higher production efficiency.

[0006] The technical solution of this utility model is as follows: a drying and preheating device for the production of waterproof membrane, comprising a drying chamber, a feeding unit located on the left side of the chamber, a discharging unit located on the right side of the chamber, a conveying unit located inside the chamber, and a drying unit; the feeding unit includes a main feeding frame and a secondary feeding frame staggered from the main feeding frame, and each of the main feeding frame and the secondary feeding frame is provided with a detachable roller shaft; the discharging unit includes a winding frame, a winding roller detachably mounted on the winding frame, and a winding motor located outside the winding frame that drives the winding roller to rotate via a chain and sprocket; the drying unit includes a main hot air unit located at the bottom of the chamber and secondary heating units distributed throughout the chamber; an exhaust unit connected to the interior of the chamber is located on the top right side of the chamber.

[0007] In the aforementioned drying and preheating device for the production of waterproof membrane, a support base is provided below the box body, and multiple corresponding support legs are provided below the support base; support plates for installing feeding units and discharging units are horizontally provided on the left and right sides of the box body; inlet and outlet for raw materials are correspondingly opened on the left and right sides of the box body.

[0008] In the aforementioned drying and preheating device for the production of waterproof membrane, the main hot air unit includes a hot air fan horizontally mounted on the top of the box, a main heater mounted on the hot air fan, and a guide plate mounted on the main heater; air inlets are provided on the front and rear sides of the box, the air inlets are located below the hot air fan, and the air inlets are provided with removable dustproof nets; air guide grooves are correspondingly provided on the guide plate; the main heater includes at least heating wires.

[0009] In the aforementioned drying and preheating device for the production of waterproof membrane, the exhaust unit includes an exhaust fan located above the box and an air collection pipe located at the top inside the box and connected to the exhaust fan; the air collection pipe is located at the top right side of the box.

[0010] In the aforementioned drying and preheating device for the production of waterproof membrane, the material conveying unit includes a plurality of correspondingly distributed material conveying rollers disposed in the box body and a reversing roller disposed on the upper right side of the box body; the box body is provided with a horizontal mounting beam for mounting the material conveying rollers.

[0011] In the aforementioned drying and preheating device for waterproof membrane production, there are four mounting beams, which are respectively located at the top and bottom of the front and rear sides of the box body; the conveying roller includes a shaft, mounting seats corresponding to both ends of the shaft, and a pressure block detachably located below the mounting seat; each mounting seat has a mounting groove for engaging the mounting beam; the pressure block is detachably located below the mounting seat by fastening screws and abuts against the bottom of the mounting beam; the pressure block is provided with an anti-slip pad layer.

[0012] In the aforementioned drying and preheating device for the production of waterproof membrane, the front side of the box is provided with an openable and closable door, and a corresponding door handle is provided on the door.

[0013] In the aforementioned drying and preheating device for the production of waterproof membrane, the secondary heating unit includes secondary heating plates distributed within the chamber and corresponding to the raw materials.

[0014] Compared with the prior art, this application extends the drying time of the roll material by setting up a drying box, and the roll material is fed into the box for vertical conveying, which is more efficient than the traditional method of drying directly by drying rollers.

[0015] By setting up a drying unit consisting of a main hot air unit at the bottom and a secondary heating unit inside, the drying efficiency is higher through the combination of hot air and heaters.

[0016] By setting up a main feed rack and a secondary feed rack, the two work together as backups. When one is in use, the other is used to prepare materials. This way, the material can be fed in time after the current material is delivered. This is much faster than the previous method of stopping the machine to disassemble and reassemble the rollers, which can reduce downtime for material preparation and improve production efficiency.

[0017] Therefore, this invention has the advantages of better drying effect and higher production efficiency. Attached Figure Description
