Description
Technical Field
[0001] This utility model relates to the field of waterproof membrane production technology, specifically to a waterproof membrane calendering machine. Background Technology
[0002] In the modern construction industry and infrastructure development, waterproofing performance is one of the core requirements for ensuring the safety of engineering structures and extending their service life. With the acceleration of urbanization, the increase in large public buildings, underground space development, and special environmental engineering projects, the performance requirements for waterproof membranes are constantly upgrading. They not only need excellent impermeability and weather resistance, but also need to adapt to the thickness, strength, and flexibility requirements of different construction scenarios. Looking at the industry's development trajectory, the production process of waterproof membranes has evolved from early manual coating and simple pressing to mechanized continuous production. In this process, calendering technology has gradually become the core processing method for polymer waterproof membranes—it applies pressure to molten polymer raw materials to achieve continuous molding and thickness control of the material, which is a key factor determining the dimensional accuracy, surface quality, and physical properties of the membrane.
[0003] The core function of a waterproof membrane calender is to heat and melt polymer raw materials, extrude and shape them, and finally calender them into a membrane substrate with uniform thickness and a smooth surface. Its workflow can be divided into four key stages: raw material pretreatment, melt plasticizing, calendering and shaping, and cooling and setting. Each stage works together to achieve continuous production.
[0004] There are many types of raw materials for polymer waterproof membranes. Different raw materials have significant differences in melt viscosity, fluidity, thermal stability and adhesion to calendering rollers. When the raw materials are changed, the diameter of the calendering rollers and the material need to be adjusted to ensure that the material can be stably formed without damaging the product quality. Existing technology involves disassembling and replacing the calendering rollers, which is very time-consuming and affects work efficiency. Utility Model Content

[0008] Preferably, the input shaft includes a solid shaft and a hollow shaft, each rotatably connected to a bearing seat on a corresponding side.

A wire is installed inside the conduit, and the ends of the conduit and the wire are connected to the power source through a rotating conductive ring.

[0009] Preferably, each circumferential surface of the calendering roll is in contact with the heating plate, and the conductor tube and conductor branch out into multiple branches connected to the heating plate.
[0010] Compared with the prior art, the beneficial effects of this utility model are: The waterproof membrane is calendered by two sets of rotating high-temperature calendering rollers. When the raw materials are changed, the two sets of rotating frames are controlled by self-locking power to move the two sets of new calendering rollers to the working position for calendering. It can adapt to the production of different waterproof membranes without disassembly, which greatly improves work efficiency.
[0011] By controlling the extension and retraction of the hydraulic cylinders, the vertical height of the two sets of rotating frames changes, allowing for convenient adjustment of the pressing gap. Attached Figure Description

[0016] The present invention will now be described in detail with reference to the accompanying drawings.
[0017] The following is in conjunction with the appendix Figure 1-2 This embodiment describes a waterproof roll calendering machine, comprising: a roll 1, which is kept straight by two traction mechanisms. Calendering rollers 2 are provided on the upper and lower sides of the roll 1, and the calendering rollers 2 are located between the two traction mechanisms. The shaft ends of the calendering rollers 2 are rotatably connected to a rotating frame 3. The rotating frame 3 has two parts, upper and lower, and each rotating frame 3 is rotatably connected to a calendering roller 2 with a different diameter and material. Each calendering roller 2 has a corresponding calendering roller 2 on the other rotating frame 3 in terms of diameter and material. The rotating frame 3 is rotatably connected to a machine frame 5 and is connected to an input shaft 4. The input shaft 4 is connected to a self-locking power source. The shaft end of each calendering roller 2 is connected to the output end of a corresponding motor 6. The motor 6 is connected to the rotating frame 3, and a heating mechanism is connected to the rotating frame 3. The heating mechanism is in contact with the calendering rollers 2.
[0018] Two traction mechanisms pull the roll 1 and the calendered roll to keep the roll 1 straight. The motor 6 drives the corresponding calendering roller 2 to rotate. The heating mechanism heats the corresponding calendering roller 2. The waterproof roll is calendered by the upper and lower sets of rotating high-temperature calendering rollers 2. When the production raw materials are changed, the two sets of input shafts 4 and the rotating frame 3 are rotated by self-locking power control. The rotating frame 3 drives the calendering roller 2 to rotate, so that the upper and lower sets of new calendering rollers 2 move to the working position for calendering. It can adapt to the production of different waterproof rolls without disassembly, which greatly improves the work efficiency.
[0019] The frame 5 is connected to the input shaft 4 via the hydraulic cylinder 7 and the bearing seat 8. The fixed end of the hydraulic cylinder 7 is connected to the frame 5, and the telescopic end of the hydraulic cylinder 7 is connected to the bearing seat 8.

[0020] By controlling the extension and retraction of the hydraulic cylinder 7, the vertical height of the two sets of input shafts 4, rotating frame 3, and calendering roller 2 can be changed, thus conveniently adjusting the pressing gap of the calendering roller 2.
[0021] The input shaft 4 includes a solid shaft 41 and a hollow shaft 42. The solid shaft 41 and the hollow shaft 42 are rotatably connected to the bearing seats 8 on the corresponding sides. The solid shaft 41 is connected to the self-locking power supply. The hollow shaft 42 is connected to a wire tube 9. The wire tube 9 is equipped with a wire. The wire tube 9 and the end of the wire are connected to the power supply through a rotating conductive ring. The wire tube 9 and the wire branch out into multiple branches 10 and are connected to the motor 6.
[0022] The power supply transmits current to the wires inside the conduit 9 by rotating the conductive ring. The rotation of the conduit 9 drives the rotating conductive ring to rotate, which prevents the wires from getting tangled and the circuit from being broken. The current is transmitted to the corresponding motor 6 through the branch 10. The motor 6 can be started and stopped by controlling the switch of the branch 10.
[0023] Each circumferential surface of the calendering roll 2 is in contact with the heating plate 11, and the conductor tube 9 and the conductor branching out into multiple branches 10 are connected to the heating plate 11.
[0024] The current is transmitted to the corresponding heating plate 11 through branch 10, and the heating plate 11 and the circumferential surface of the calendering roller 2 transfer heat.
