[0002] Waterproof membrane is mainly used for building walls, roofs, tunnels, roads, landfills, etc. It is a flexible building material product that can be rolled into a roll to prevent external rainwater and groundwater leakage. As a leak-proof connection between the project foundation and the building, it is the first barrier to waterproofing the entire project and plays a vital role in the entire project.

[0003] In the related art, polymer waterproof roll is a waterproof roll prepared based on polymer materials. During the production process of polymer waterproof roll, the polymer material is heated and extruded in an extruder and then calendered to a predetermined thickness through a calendering device. The calendering process has high requirements on the process temperature of the waterproof roll. If the temperature at a certain position of the calendering roller is too high, the waterproof roll will not follow the roller, resulting in uneven thickness of the waterproof roll after calendering.

[0040] Hereinafter, only certain exemplary embodiments are briefly described. As will be appreciated by those skilled in the art, the described embodiments may be modified in various ways without departing from the spirit or scope of the present disclosure. Therefore, the drawings and description are to be considered as illustrative in nature and not restrictive.

[0041] Figure 1 A schematic structural diagram of a calendering device according to an embodiment of the present disclosure is shown. Figure 1 As one aspect of the present disclosure, an embodiment of the present disclosure provides a calendering device 1, which is a device for calendering a membrane material to a predetermined thickness. Preferably, the calendering device 1 according to an embodiment of the present disclosure can be used for calendering waterproof membranes.

[0042] The calendering device 1 includes a frame and a calendering roller assembly 10 . The calendering roller assembly 10 includes a first roller body 100 . The calendering roller assembly 10 is arranged on the frame.

[0043] In some embodiments, see Figure 1 The calendering equipment 1 of the embodiment of the present disclosure also includes a driving unit, a second roller 20 and a third roller 30. The central axes of the second roller 20 and the third roller 30 are respectively parallel to the central axes of the first roller 100, and the outer walls of the second roller 20 and the outer walls of the third roller 30 are respectively in contact with the outer walls of the first roller 100. The driving unit is used to drive the second roller 20 and the third roller 30 to rotate. Based on this, the waterproof membrane is sequentially passed through the gap between the second roller 20 and the first roller 100, and the gap between the first roller 100 and the third roller 30, thereby realizing secondary calendering of the waterproof membrane, thereby calendering the waterproof membrane to a predetermined thickness.

[0044] In the embodiment of the present disclosure, the second roller body 20 is disposed above the calendering roller assembly 10 , and the third roller body 30 is disposed below the calendering roller assembly 10 .

[0045] In some embodiments, the drive unit includes a motor and a reducer, and the motor is connected to the second roller 20 through the reducer to achieve rotation of the second roller 20. It is understood that the transmission method of the third roller 30 is similar to that of the second roller 20, and the motor is connected to the third roller 30 through the reducer to achieve rotation of the third roller 30.

[0046] It can be understood that the calendering equipment 1 also includes other necessary or unnecessary structures, such as a conveying system for conveying waterproof membranes, a loading system for loading waterproof membranes, etc., which will not be elaborated here.

[0047] Figure 2 shows a side view of a calendering roller assembly according to an embodiment of the present disclosure, Figure 3A cross-sectional view showing a calendering roller assembly according to an embodiment of the present disclosure, Figure 4 Show Figure 3 A magnified schematic diagram in the middle. Figure 5 A schematic structural diagram of the first roller body according to an embodiment of the present disclosure is shown. Figures 2 to 5 The calendering roller assembly 10 includes a first roller 100, a driving mechanism, and a cooling mechanism 300. The driving mechanism is in transmission connection with the first roller 100 and is used to drive the first roller 100 to rotate. Through the rotation of the first roller 100, the second roller 20, and the third roller 30, the waterproof membrane is sequentially passed through the gap between the second roller 20 and the first roller 100, and the gap between the first roller 100 and the third roller 30, thereby achieving secondary calendering of the waterproof membrane, thereby calendering the waterproof membrane to a predetermined thickness.

[0048] See also Figure 2 The cooling mechanism 300 includes a pneumatic triplet 310, an air blowing pipe 320, and an air supply source for providing cooling gas to the air blowing pipe 320. The air supply source is connected to the air blowing pipe 320 through the pneumatic triplet 310. The air blowing pipe 320 is defined with at least one air outlet, and the air outlet faces the first roller body 100.

[0049] Exemplarily, the pneumatic triplex 310 includes a filter valve and a pressure reducing valve. The cooling gas first enters the air filter, and the filter element filters out solid particles and moisture in the cooling gas. The filtered cooling gas enters the pressure reducing valve, and the pressure reducing valve adjusts the cooling gas pressure to the required working pressure.

[0050] It should be noted that the gas supply source can be used to provide cooling gas to the air blowing pipe 320. For example, the gas supply source can provide inert gas to the first roller body 100.

[0051] According to the calendering roller assembly 10 of the embodiment of the present disclosure, the air supply source provides cooling air to the air blowing pipe 320 via the pneumatic triplet 310. A pneumatic triplet 310 is provided between the air supply source and the air blowing pipe 320. The pneumatic triplet 310 is used to purify, filter, and reduce the pressure of the cooling air. The cooling air in the air blowing pipe 320 is blown out toward the first roller body 100 through the air outlet, thereby accelerating the air flow around the first roller body 100, and allowing the cooling air to remove the heat from the first roller body 100, thereby cooling the first roller body 100. This prevents the temperature of a certain position on the first roller body 100 from being too high, and prevents the waterproofing coil from detaching from the first roller body 100 due to the excessive temperature of a certain position on the first roller body 100 during the calendering process, thereby preventing the waterproofing coil from being unevenly calendered. This makes the calendering process of the calendering device 1 including the calendering roller assembly 10 of the present disclosure more stable.

[0052] In the embodiments of the present disclosure, see Figure 1Since the first roller body 100 is arranged between the second roller body 20 and the third roller body 30, and the outer side walls of the first roller body 100 are respectively in contact with the outer side walls of the second roller body 20 and the outer side walls of the third roller body 30, the present disclosure cools the first roller body 100 through the cooling mechanism 300, and the first roller body 100 realizes heat transfer by respectively contacting with the second roller body 20 and the third roller body 30, thereby realizing cooling of the second roller body 20 and the third roller body 30.

[0053] In some embodiments, see Figures 3 to 5 The calendering roller assembly 10 of the embodiment of the present disclosure further includes a water tank, a connector 400, a delivery pipe 500 and a sleeve 600. The connector 400 is defined by a liquid inlet 410 and a liquid outlet 420. The first roller body 100 is defined by a cavity. The sleeve 600 is arranged in the cavity. A heat exchange cavity 700 is defined between the inner wall of the cavity and the outer wall of the sleeve 600. That is, the cooling liquid flow channel in the heat exchange cavity 700 can take away part of the heat from the surface of the first roller body 100. The water tank is connected to the heat exchange cavity 700 through the liquid inlet 410 and the delivery pipe 500, and the liquid outlet 420 is connected to the heat exchange cavity 700.

[0054] According to the embodiment of the present disclosure, the liquid inlet 410 of the connector 400 is connected to the water tank, and the coolant in the water tank is introduced into the heat exchange chamber 700 through the delivery pipe 500. The flow of the coolant in the heat exchange chamber 700 takes away the heat on the first roller body 100, thereby achieving the cooling effect of the first roller body 100. The coolant will flow out in the heat exchange chamber 700 toward the liquid outlet 420.

[0055] In some embodiments, see Figure 3 and Figure 4 The delivery tube 500 is sequentially arranged through the sleeve 600 and the first roller body 100, thereby leading one end of the delivery tube 500 to the outside of the first roller body 100. One end of the delivery tube 500 is connected to the liquid inlet 410, and the other end of the delivery tube 500 is connected to the end of the heat exchange chamber 700 away from the connector 400. This arrangement enables the first end of the heat exchange chamber 700 to be connected to the other end of the delivery tube 500, and the second end of the heat exchange chamber 700 to be connected to the liquid outlet 420 of the connector 400. This increases the flow path of the heat exchange chamber 700, thereby increasing the contact area between the heat exchange chamber 700 and the first roller body 100, and facilitating improved cooling of the first roller body 100. The first end of the heat exchange chamber 700 is the end away from the connector, and the second end of the heat exchange chamber 700 is the end close to the connector.

[0056] In some embodiments, the central axis of the conveying tube 500 and the central axis of the first roller body 100 are coaxially arranged.

[0057] In some embodiments, see Figure 3 and Figure 4The connector 400 includes a rotary joint, one end of which is connected to the water tank, and the other end of which is connected to the delivery pipe 500. The liquid inlet 410 of the rotary joint is connected to the water tank, and the liquid outlet 420 of the rotary joint is connected to the heat exchange chamber 700. The arrangement of the rotary joint allows the first roller 100 and the water tank to rotate relative to each other while also allowing the liquid inlet 410 of the rotary joint to be connected to the water tank, and the liquid outlet 420 of the rotary joint to be connected to the heat exchange chamber 700. This ensures that the rotation of the first roller 100 does not affect the inflow and outflow of liquid into and out of the heat exchange chamber. Of course, in addition to the above method, the connector 400 can also adopt a hose method. When the rotating shaft first roller 100 rotates, the hose will be twisted to a certain extent, but after the twisting, the water tank and the delivery pipe 500 can still be connected.

[0058] In some embodiments, see Figure 2 The cooling mechanism 300 also includes at least one universal tube 800, and at least one universal tube 800 corresponds to at least one air outlet. One end of the universal tube 800 is connected to the corresponding air outlet, and the other end of the universal tube 800 faces the first roller body 100. The universal tube 800 has high plasticity. The universal tube 800 is easy to completely and completely change its deformation under the action of external force, and has the ability to maintain its shape unchanged, so that the universal tube 800 can be bent so that the other end of the universal tube 800 faces the specified position on the first roller body 100, thereby achieving local cooling of the first roller body 100.

[0059] According to the embodiment of the present disclosure, since there are many factors that affect the temperature of the first roller body 100, when the temperature of a certain position of the first roller body 100 is too high, the angle of the universal tube 800 can be adjusted, and then the direction of the air outlet end of the universal tube 800 can be adjusted, thereby achieving cooling of the certain position of the first roller body 100.

[0060] It is understood that the universal tube 800 in the embodiment of the present disclosure is a bamboo tube that can be deformed under the action of an external force. It is understood that the universal tube 800 can also be other deformable structures, which are not limited here.

[0061] In some embodiments, see Figure 2 The cooling mechanism 300 also includes at least one throttle valve 900. There is a one-to-one correspondence between the at least one throttle valve 900, the at least one air outlet, and the at least one universal tube 800. The input end of the throttle valve 900 is connected to the corresponding air outlet, and the output end of the throttle valve 900 is connected to the corresponding universal tube 800. The throttle valve 900 can adjust the air pressure entering the universal tube 800 from the blowing pipe 320, and then adjust the gas flow rate blown from the universal tube 800 to the first roller body 100, thereby adjusting the cooling effect of the cooling mechanism 300 on the first roller body 100.

[0062] In some embodiments, see Figure 2 The cooling mechanism 300 further includes at least one blowing nozzle 200, which corresponds to at least one universal tube 800. The blowing nozzle 200 is disposed at the other end of the corresponding universal tube 800. The provision of the blowing nozzle can converge the gas discharged from the universal tube 800, thereby improving the cooling effect of the cooling mechanism 300 on a certain position of the first roller body 100.

[0063] The blowing nozzle 200 may be a circular blowing nozzle 200 or a flat blowing nozzle 200. Of course, in some other examples, the blowing nozzle 200 may have other shapes, for example, the blowing nozzle 200 may be an elliptical ring, or the blowing nozzle 200 may be cylindrical. The shape and structure of the blowing nozzle 200 are not limited in the embodiments of the present disclosure.

[0067] In the present disclosure, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature includes the first feature being directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature includes the first feature being directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.
