Description

Technical Field

[0001] The utility model relates to the technical field of waterproof coiled material dipping, in particular to a dipping device for waterproof coiled material production. Background Art

[0002] The dipping process of waterproof membrane is one of the important steps in preparing waterproof membrane. It mainly involves soaking the base material of the waterproof membrane in melted asphalt (or other colloidal materials) to fully impregnate it and form a waterproof layer.

[0003] During the existing waterproof membrane dipping production process, the base material of the waterproof membrane will absorb a large amount of heat during the dipping process, causing the base material temperature to rise too quickly or even overheat. Overheating will affect the quality of the waterproof membrane product, causing deformation, thermal damage or other quality problems. In addition, due to factors such as the viscosity and surface tension of the colloid material, bubbles will be generated during the dipping process. The presence of bubbles will reduce the adhesion of the coating and the product performance of the waterproof membrane. Utility Model Content

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0028] In the description of the present invention, it should be understood that the terms "longitudinal", "transverse", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like to indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0029] Combine Figures 1 to 2 The illustrated device for dipping waterproof membrane production includes a dipping tank 1 for dipping. A heating device for heating the colloid is provided at the bottom of the immersion tank 1. The heating device can specifically be a heating furnace and a heating barrel. Heating the colloid can enhance its fluidity, which is convenient for subsequent dipping. Round rollers are provided above the two side walls of the immersion tank 1. The provision of the round rollers can make the waterproof membrane smoother when entering and exiting the immersion tank 1, and effectively protect the base material of the waterproof membrane, avoid direct contact with the side walls of the immersion tank 1 during the process of entering and exiting the immersion tank 1, and reduce the risk of friction and damage.

[0030] like Figure 1 As shown, a first round roller 3, a second round roller 4 and a support frame 2 are provided inside the soaking tank 1, wherein the support frame 2 is located between the first round roller 3 and the second round roller 4, and is used to separate the space inside the soaking tank 1, and the first round roller 3 and the second round roller 4 are located below the support frame 2. In some embodiments, during the process of dipping the substrate, the colloid in the soaking tank 1 needs to overflow the first round roller 3 and the second round roller 4, and the substrate rotates from the bottom of the first round roller 3 and the second round roller 4 to contact.

[0031] In some embodiments, as Figure 1As shown, a fifth roller 15 is provided below the first roller 3 and is connected to the fifth roller 15 via a synchronous belt. The substrate passes between the first roller 3 and the fifth roller 15 to achieve preliminary extrusion of the coil.

[0032] Specifically, such as Figure 1 As shown, a heat dissipation device is also provided in the immersion tank 1, and a third round roller 6 and a fourth round roller 7 are respectively provided at both ends of the support frame 2. The heat dissipation device is fixedly mounted on the support frame 2 and is located between the third round roller 6 and the fourth round roller 7. In some embodiments, during the process of dipping the substrate into the glue, the third round roller 6, the fourth round roller 7 and the heat dissipation device are above the colloid to ensure that they are not soaked. The heat dissipation device specifically adopts a fan 5.

[0033] In the above structure, after the colloid is heated to a suitable temperature, the substrate enters the immersion tank 1 and begins the dipping process. The substrate rotates and contacts with the bottom of the first round roller 3, and the substrate is initially dipped in the glue. Then, the substrate rolls and contacts with the third round roller 6 and the fourth round roller 7. At this time, the substrate is not dipped in the glue, and the fan 5 is started to force the pre-heating of the substrate between the third round roller 6 and the fourth round roller 7. Because the substrate absorbs a lot of heat during the dipping process, if the heat is not dissipated in time, it may cause the substrate to overheat, affecting the product quality and the subsequent process steps. Through micro-forced heat dissipation, the temperature of the substrate can be quickly reduced, the production efficiency can be improved, and the substrate can be avoided from being damaged or deformed by heat. After heat dissipation, the substrate rotates and contacts with the bottom of the second round roller 4 and is dipped in the immersion tank 1 again.

[0034] like Figure 1 As shown, an extrusion device is provided in the soaking tank 1, and the extrusion device is located above the second round roller 4. The extrusion device includes a first extrusion pair of rollers 8 and a second extrusion pair of rollers 9 arranged side by side, and the first extrusion pair of rollers 8 and the second extrusion pair of rollers 9 are driven by a belt drive or a chain drive to achieve synchronous transmission.

[0035] In the above structure, by arranging the first pair of extrusion rollers 8 and the second pair of extrusion rollers 9 side by side, it can be ensured that the material is subjected to uniform extrusion after soaking, so that it is fully and evenly processed under pressure, and that the material can eliminate excess liquid or bubbles after soaking. The first pair of extrusion rollers 8 and the second pair of extrusion rollers 9 are synchronously driven by belt drive or chain drive to ensure coordinated operation between the two and avoid deviation or asynchrony.

[0036] In some embodiments, a defoaming device is provided between the first extrusion roller pair 8 and the second extrusion roller, and the defoaming device includes a needle 13 for puncturing the substrate after dipping.

[0037] Specifically, such as Figure 1 and Figure 2As shown, a cam 10 driven by a motor is provided above the first pair of extrusion rollers 8 and the second pair of extrusion rollers 9, and a limit frame 11 is provided directly below the cam 10. A through hole is provided at the bottom of the limit frame 11, and a connecting column 12 connected with a needle 13 passes through the through hole and is slidably connected to the limit frame 11. The cam 10 contacts the top of the connecting column 12, so that the needle 13 at the bottom of the connecting column 12 makes a reciprocating linear motion, thereby puncturing the substrate between the first pair of extrusion rollers 8 and the second pair of extrusion rollers 9.

[0038] In some embodiments, as Figure 2 As shown, the connecting column 12 is stepped. More specifically, one end of the connecting column 12 is in the shape of a thicker column and the other end is in the shape of a thinner column. The needle 13 is fixed to the thinner section of the connecting column 12. The cam 10 contacts the top of the thicker section of the connecting column 12 during rotation. A reset spring 14 is sleeved on the thinner section of the connecting column 12. The reset spring 14 is located between the bottom of the limit frame 11 and the transition section of the connecting column 12. During the contact between the cam 10 and the connection, the needle 13 moves downward and punctures a hole in the substrate between the first extrusion roller 8 and the second extrusion roller 9. Because the reset spring 14 is in a compressed state during the downward movement of the connecting column 12, when the cam 10 no longer contacts the connecting column 12, the connecting column 12 resets upward under the action of the reset spring 14.

[0039] During specific use, the heating device in the immersion tank 1 heats the colloid. After being heated to an appropriate temperature, the base material of the waterproof membrane enters the immersion tank 1 for dipping. Specifically, the base material rolls in contact with the bottom of the first round roller 3 immersed in the colloid, and then the base material extends out of the colloid and rolls in contact with the top of the third round roller 6 and the fourth round roller 7. The fan 5 is started to dissipate heat for the base material. After that, the base material contacts the bottom of the second round roller 4 immersed in the colloid again and is dipped in glue again. After that, the base material extends out of the colloid and completes the extrusion process between the first extrusion pair of rollers 8 and the second extrusion pair of rollers 9. While the base material is being squeezed, the motor driving the cam 10 is started, and the cam 10 rotates and contacts the connecting column 12, causing the needle 13 at the bottom of the connecting column 12 to move downward to puncture the base material. When the cam 10 is not in contact with the connecting column 12, the connecting column 12 is reset upward under the action of the reset spring 14.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. The scope of patent protection of the present invention shall be based on the claims. Any equivalent structural changes made using the description and drawings of the present invention shall also be included in the scope of protection of the present invention.
