Description

Technical Field

[0001] The utility model belongs to the field of waterproof coiled materials, in particular to a glue coating pre-pressing device for waterproof coiled materials. Background Art

[0002] Waterproof membrane is mainly used for building walls, roofs, tunnels, roads, landfills, etc. It is a kind of flexible building material product that can be rolled into a roll to resist the leakage of rainwater and groundwater from the outside. As a leak-free connection between the engineering foundation and the building, it is the first barrier to waterproofing the entire project and plays a vital role in the entire project. It is a waterproof material product made by impregnating asphalt or polymer waterproof materials on the tire body. The waterproof membrane has good water resistance, stability to temperature changes, certain mechanical strength, elongation and fracture resistance, certain flexibility and aging resistance, etc. When the waterproof membrane is produced and processed, the tire cloth needs to be coated with glue. In order to ensure the efficiency of the glue coating, a pre-pressing device is usually used to squeeze and flatten the tire cloth to avoid the wrinkles of the tire cloth from affecting the glue coating. However, it still has the following disadvantages in actual use:

[0003] 1. Before the waterproofing coil is coated with glue by the glue coating equipment, the wrinkles on the surface of the tire cloth can be removed by squeezing the tire cloth with two or more leveling wheels of the leveling structure. However, in actual use, the contact time between a single leveling wheel and the tire cloth is short, and the squeezing time of the tire cloth is insufficient, making it difficult to effectively level the larger wrinkles on the surface of the tire cloth;

[0004] 2. When the pre-pressing device is leveling the tire cloth, since the surface of the tire cloth is relatively smooth and there are slight differences in the thickness of the tire cloth, slippage or excessive pressure may occur between the leveling wheel and the tire cloth during the actual processing, reducing the leveling effect. Utility Model Content

[0005] The utility model aims to provide a glue pre-pressing device for waterproof coiled materials. Through a support frame and a support base, the utility model solves the problems that, when the glue pre-pressing device is actually used, a single leveling wheel is difficult to contact with the tire cloth for a long time, the extrusion time for the tire cloth is insufficient, the leveling effect is not good, the surface of the tire cloth is relatively smooth, the thickness of the tire cloth may have slight differences, and the tire cloth may slip between the leveling wheel during processing.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model is a glue coating pre-pressing device for waterproof coiled materials, comprising a support frame and a support base, wherein the two ends of the bottom of the support frame are respectively provided with a flattening plate and a rotating rod, the outer peripheral surface of the rotating rod is provided with an extrusion airbag, the bottom of the support frame is provided with a support base, and the two ends of the top of the support base are respectively provided with a heating plate and a rotating roller;

[0008] The flattening plate can be used to extrude tire cloths of different thicknesses for a longer period of time to ensure the flattening time. By inflating the extrusion airbag, it can be expanded and squeezed on the upper side of the tire cloth, and a certain pressure is exerted on the tire cloth to ensure stable squeezing of the tire cloth when the thickness of the tire cloth changes slightly, and to avoid the tire cloth slipping during movement. The heating plate can heat the tire cloth to improve the flattening efficiency. The rotation of the rotating rod can drive the tire cloth to move, ensuring that the moving speed of the tire cloth when passing through the glue pre-pressing device is consistent with the retracting and releasing speed of the retracting and releasing device.

[0009] Furthermore, a limiting rod is welded and fixed around the top of the leveling plate, a compression spring is clamped on the top of the leveling plate, the limiting rod penetrates and is inserted into the bottom of the support frame, and the compression spring is clamped on the bottom of the support frame;

[0010] The leveling plate can be squeezed by the squeezing spring, so that the leveling plate can squeeze tire cloths of different sizes, prolong the squeezing time of the tire cloth, and improve the leveling efficiency. The leveling plate can be limited by the limiting rod to ensure that the pressure of the leveling plate on the tire cloth at different positions is consistent.

[0011] Furthermore, the outer circumference of the rotating rod is clamped with a pressure sensing component, one end of the rotating rod is clamped with a pressure sensor, the extrusion airbag is clamped on the outer circumference of the pressure sensing component, one end of the rotating rod is penetrated and clamped with an air pump, and the air pump is penetrated and connected with the extrusion airbag;

[0012] During the pre-pressing and leveling process of the tire cloth, the air pump is used to inflate the extrusion airbag, causing the extrusion airbag to expand and squeeze the upper side of the tire cloth. The pressure sensor and pressure sensing component can monitor the pressure of the extrusion airbag on the tire cloth to keep the pressure within an appropriate range to avoid slipping between the rotating roller and the tire cloth due to slight differences in the thickness of the tire cloth.

[0013] Furthermore, a first rotating support plate is welded and fixed to one side of the support frame, the rotating rod is clamped to one side of the first rotating support plate, and the first rotating support plate is located at the other end of the rotating rod relative to the air pump;

[0014] The rotating rod can rotate with the first rotating support plate as the axis, so that rolling friction occurs between the extruded airbag and the tire cloth, thereby preventing deformation of the tire cloth caused by excessive friction of sliding friction.

[0015] Furthermore, an anti-skid pad is clamped and fixed on the top of the heating plate, the leveling plate is suspended from the top of the heating plate, second rotating support plates are welded and fixed on both sides of the support base, the rotating roller is clamped between the two second rotating support plates, a rotating motor is clamped through the other side of the second rotating support plate relative to the rotating roller, the rotating motor is connected to the rotating roller in a transmission manner, and the rotating rod is suspended from the top of the rotating roller;

[0016] The tire cloth can be heated by the heating plate, which can greatly improve the leveling efficiency. The rotating motor drives the rotating rod to rotate, which further drives the tire cloth to move, ensuring that the moving speed of the tire cloth when passing through the glue pre-pressing device is consistent with the retracting speed of the retracting device.

[0017] The utility model has the following beneficial effects:

[0018] 1. The utility model solves the problem that before the tire cloth of the waterproof coiled material is glued by the glue coating equipment, the wrinkles on the tire cloth can be removed by squeezing the tire cloth with two or more leveling wheels of the leveling structure. In actual use, the contact time between a single leveling wheel and the tire cloth is short, the squeezing time of the tire cloth is insufficient, and it is difficult to effectively level the larger wrinkles on the tire cloth surface. The pre-pressing and leveling time of the tire cloth can be extended by a large leveling plate, and the leveling efficiency can be improved. The heating of the tire cloth by the heating plate can further improve the leveling efficiency of the tire cloth, and avoid the wrinkles of the tire cloth from affecting the glue coating.

[0019] 2. The utility model solves the problem that when the pre-pressing device is leveling the tire cloth, due to the relatively smooth surface of the tire cloth and slight differences in the thickness of the tire cloth, slippage or excessive pressure may occur between the leveling wheel and the tire cloth during the actual processing, thereby reducing the leveling effect by arranging a support frame and a support base. The air pump inflates the extrusion airbag to squeeze the tire cloth and generate a certain pressure, thereby avoiding excessive squeezing of the tire cloth and slippage between the rotating roller and the tire cloth due to slight differences in the thickness of the tire cloth.

[0027] See also Figure 1-4 As shown, the utility model is a glue pre-pressing device for waterproof coiled material, comprising a support frame 1 and a support base 2, a flattening plate 101 and a rotating rod 106 are respectively arranged at both ends of the bottom of the support frame 1, an extrusion airbag 103 is arranged on the outer peripheral surface of the rotating rod 106, a support base 2 is arranged at the bottom of the support frame 1, and a heating plate 201 and a rotating roller 202 are respectively arranged at both ends of the top of the support base 2;

[0028] One end of the tire cloth is inserted between the heating plate 201 and the leveling plate 101, and one end of the tire cloth is passed between the rotating rod 106 and the rotating roller 202, so that one end of the tire cloth is connected to the glue coating device. During the glue coating process of the tire cloth, the extrusion airbag 103 is inflated by the air pump 108, so that the extrusion airbag 103 expands and squeezes the upper side of the tire cloth. The pressure of the extrusion airbag 103 on the tire cloth is monitored by the pressure sensing component 107, and the inflation of the extrusion airbag 103 is stopped when the pressure is appropriate. The rotating motor 204 drives the rotating roller 202 to rotate, so that the tire cloth moves through the friction between the extrusion airbag 103, the rotating roller 202 and the tire cloth. When the unrolled tire cloth moves into the glue coating pre-pressing device, the tire cloths of different thicknesses are squeezed for a long time by the leveling plate 101, and the tire cloth is heated by the heating plate 201 to improve the leveling effect.

[0030] During the pre-pressing and flattening process of the tire cloth, the air pump 108 is controlled to inflate the squeezing airbag 103 so that the squeezing airbag 103 expands and squeezes the upper side of the tire cloth. The pressure of the squeezing airbag 103 on the tire cloth is monitored by the pressure sensing component 107, and the pressure is displayed by the pressure sensor 109. When the appropriate pressure is reached, the air pump 108 is turned off. When the unrolled tire cloth passes through the glue pre-pressing device, the flattening plate 101 is squeezed by the squeezing spring 104, and tire cloths of different thicknesses are further squeezed by the flattening plate 101 to extend the squeezing time of the tire cloth.

[0033] The specific working principle of the utility model is as follows: during the pre-pressing and flattening process of the tire cloth, one end of the tire cloth is inserted between the heating plate 201 and the flattening plate 101, and one end of the tire cloth is passed between the rotating rod 106 and the rotating roller 202, so that one end of the tire cloth is connected to the gluing equipment, the winding equipment, etc., and the air pump 108 is controlled to inflate the squeezing airbag 103 so that the squeezing airbag 103 expands and squeezes the upper side of the tire cloth. The pressure of the squeezing airbag 103 on the tire cloth is monitored by the pressure sensing component 107, and the pressure sensor 109 is used to monitor the pressure of the squeezing airbag 103 on the tire cloth. The force is displayed, and when the appropriate pressure is reached, the air pump 108 is turned off, and the glue pre-pressing device, glue coating equipment, winding and unwinding equipment, etc. are started. The rotating motor 204 drives the rotating roller 202 to rotate, and further drives the tire cloth to move. When the unrolled tire cloth moves to the lower side of the flattening plate 101, the heating plate 201 heats the tire cloth, and the squeezing spring 104 squeezes the flattening plate 101. The flattening plate 101 further squeezes tire cloths of different thicknesses, prolongs the squeezing time of the tire cloth, and removes wrinkles on the surface of the tire cloth.
