Description

Technical Field

[0001] The utility model belongs to the technical field of machinery and relates to a laminating device used for the production of composite tarpaulins. Background Art

[0002] Composite tarpaulin is a tarpaulin material made of base fabric and surface material through a special process. The base fabric is usually a mesh woven from yarn, and the surface material is usually a PVC film. Composite tarpaulin has good waterproofness, weather resistance and mechanical strength. It is widely used in construction fencing, cargo transportation covering, temporary warehousing, open-air exhibitions, agricultural greenhouses, swimming pool sunshade roofs, marine covers and many other occasions.

[0003] The production process of the traditional composite tarpaulin production and laminating device is to apply a layer of special glue on one side of the mesh, and then quickly laminate the glue-coated mesh and the PVC film together by hot pressing. After the first side is completely cooled and fixed and firmly bonded, the mesh is turned over and the same gluing and laminating process is performed on the other side of the mesh. After laminating, it is cooled and fixed. The two gluing and laminating processes increase the production steps, lengthen the production cycle, and reduce the production efficiency. At the same time, it is difficult to ensure consistency in the two gluing and laminating processes, which affects product quality. Utility Model Content

[0004] The purpose of the utility model is to provide a laminating device for composite tarpaulin production with high production efficiency and high product quality in view of the above problems existing in the prior art.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0006] A laminating device for composite tarpaulin production, characterized in that it includes a mesh pretreatment component, a base film pretreatment component, a face mask pretreatment component, a sizing component, a conveying component, a laminating component, a cooling component and a winding component, wherein the base film pretreatment component and the face mask pretreatment component are arranged symmetrically on the left and right, the mesh pretreatment component is arranged above the base film pretreatment component, the conveying component is arranged between the base film pretreatment component and the face mask pretreatment component, the number of the sizing components is two, and the two sizing components are respectively arranged between the base film pretreatment component and the conveying component and between the face mask pretreatment component and the conveying component, the laminating component is arranged below the conveying component, the cooling component is arranged below the laminating component, and the winding component is arranged on the right side of the cooling component.

[0007] The laminating device for composite tarpaulin production performs pretreatment operations such as unwinding, preheating, and leveling on the mesh through the setting of the mesh pretreatment component, so as to ensure that the surface of the mesh is in good condition, which is conducive to the subsequent laminating with the PVC film; the bottom film pretreatment component and the surface film pretreatment component are respectively set to perform pretreatment operations such as unwinding, preheating, and leveling on the bottom PVC film (bottom film) and the surface PVC film (surface mask) to be laminated with the mesh, so as to facilitate the subsequent sizing operation to improve the bonding effect of the glue and the PVC film; the glue is evenly coated on the upper surface of the bottom film and the surface mask through the setting of two independent sizing components, so as to ensure the quality and uniform thickness of the bonding layer; the mesh, coating, and the like are sizingly coated on the mesh and the surface mask through the setting of the conveying component. The base film with glue and the surface film coated with glue are pulled and conveyed so that the three are conveyed to the direction of the pressing component at the same time; the mesh cloth, the base film coated with glue and the surface film are tightly pressed at a certain temperature and pressure through the setting of the pressing component. At this time, the mesh cloth is located between the base film and the surface film, and the three are tightly fitted to form a tarpaulin; the cooling component is set to quickly cool the bonded tarpaulin, so that the glue solidifies quickly, the bonding strength is enhanced, and the tarpaulin is helped to restore its flatness to avoid deformation caused by thermal stress; the winding component is set to pull the tarpaulin to ensure the continuity of the production process, and the tarpaulin after cooling and shaping is orderly rolled up to facilitate subsequent storage, transportation and further processing.

[0008] In the above-mentioned laminating device for composite tarpaulin production, the conveying assembly includes three conveying rollers and three motors. The conveying rollers can rotate circumferentially. The three conveying rollers are respectively arranged on the right side of the mesh pretreatment assembly, the right side of the bottom film pretreatment assembly and the left side of the face mask pretreatment assembly. The three motors are connected to the three conveying rollers one by one.

[0009] The three motors can respectively drive the three conveying rollers to rotate circumferentially, so that the three conveying rollers operate independently, and the three conveying rollers are respectively used to convey the mesh cloth, the base film coated with glue, and the face mask coated with glue.

[0010] In the above-mentioned laminating device for composite tarpaulin production, the mesh pretreatment component includes a reel and a flattening roller, both of which can rotate circumferentially, and two flattening rollers are arranged opposite each other up and down, with a gap between the two flattening rollers and the flattening rollers are located on the side close to the conveying roller, and an electric heating wire is provided inside the flattening roller.

[0011] The mesh pretreatment component consists of a unwinding roller and a leveling roller. The unwinding roller is used to load untreated mesh raw materials. Under the traction of the conveying roller, the unwinding roller rotates to unwind, and the mesh is pulled out, unfolded and conveyed to the leveling roller. The mesh passes through the gap between the two leveling rollers. The leveling roller can be heated by the setting of the electric heating wire. At the same time, the two leveling rollers exert pressure on the mesh. Due to the friction resistance between the mesh and the two leveling rollers and under the traction of the conveying roller, the two leveling rollers can rotate relatively when the mesh passes through the two leveling rollers, so that the mesh is preheated and flattened after passing through the two leveling rollers to eliminate wrinkles on the mesh and improve the subsequent bonding performance of the mesh with glue or PVC film.

[0012] In the above-mentioned laminating device for composite tarpaulin production, the structures of the bottom film pretreatment component and the surface film pretreatment component are consistent with the structure of the mesh pretreatment component and the leveling rollers of the three are all located close to the conveying roller.

[0013] The base film pretreatment component and the surface film pretreatment component are also composed of unwinding rollers and leveling rollers. The base film and surface film loaded on the corresponding unwinding rollers are transported to the subsequent process after unwinding, preheating and leveling. The side of the base film and surface film to be coated with glue faces upward to ensure the flatness of the base film and surface film and the bonding performance with the glue, thereby ensuring the subsequent fitting effect and stability of the base film, mesh cloth and surface mask, and ensuring the production quality of the tarpaulin.

[0014] In the above-mentioned bonding device for composite tarpaulin production, the sizing assembly includes a glue storage barrel, a glue outlet and a coating roller. The glue storage barrel has an internal cavity, the glue outlet is opened below the glue storage barrel and the glue outlet is located between the leveling roller and the conveying roller, the coating roller is located between the glue outlet and the conveying roller, and the coating roller can rotate circumferentially.

[0015] The glue storage barrel is used to store glue for bonding tarpaulin. The two glue storage barrels are respectively located above the base film and the surface mask. The glue outlets opened below the two glue storage barrels are also respectively located above the base film and the surface mask. After a proper amount of glue flows out from the glue outlet, it falls on the base film and the surface mask below. The two coating rollers are respectively against the upper surfaces of the base film and the surface mask, and the width of the coating rollers matches the width of the base film and the surface mask. Then, under the traction of the conveying rollers on the base film and the surface mask, the two coating rollers roll respectively to evenly coat the glue on the base film and the surface mask, so that the upper surfaces of the base film and the surface mask are evenly covered with glue and the thickness of the glue layer is uniform, so as to ensure the best bonding effect between the subsequent base film and the mesh cloth, and the surface mask and the mesh cloth. At the same time, since the base film gluing and the surface mask gluing are carried out independently and synchronously, the mesh cloth is made during the subsequent pressing process.

[0016] In the above-mentioned laminating device for composite tarpaulin production, the laminating assembly includes two pressing rollers, which are symmetrically arranged with a gap between them, and the pressing rollers can rotate circumferentially, and the pressing rollers have electric heating wires inside.

[0017] The base film, mesh cloth and face mask coated with glue pass through two pressing rollers. The appropriate gap between the two pressing rollers allows the base film, mesh cloth and face mask to be acted on by the two pressing rollers at the same time. The two pressing rollers rotate in opposite directions to effectively and evenly press the materials to ensure a tight bond between the base film, mesh cloth and face mask. The pressing rollers are embedded with electric heating wires, which heat the pressing rollers. The glue is quickly solidified after being pressurized and heated during the pressing process, thereby enhancing the bonding effect. At the same time, hot pressing can also eliminate possible stress inside the material, thereby ensuring the final flatness and dimensional stability of the tarpaulin after bonding, thereby improving production efficiency and quality.

[0018] In the above-mentioned laminating device for composite tarpaulin production, the cooling assembly includes a plurality of cooling rollers, which can rotate circumferentially. The plurality of cooling rollers are arranged in sequence from left to right and the cooling roller on the far left is located below the two pressure rollers.

[0019] A number of cooling rollers that can rotate in a circumferential direction are arranged to form a continuous cooling working surface, and the cooling roller on the far left is located below the pressing roller, so that the tarpaulin formed after hot pressing by the two pressing rollers can contact the cooling roller at the first time to start the cooling process. The tarpaulin passes through a number of cooling rollers in turn in an S-shaped path for cooling, which is conducive to quickly reducing the temperature of the tarpaulin after hot pressing, further enhancing the bonding effect between the base film, mesh cloth and surface film, and also allowing the tarpaulin to be shaped, preventing the tarpaulin from being deformed due to excessive temperature after hot pressing.

[0020] In the above-mentioned laminating device for composite tarpaulin production, the winding assembly includes a winding roller and a motor. The winding roller is located on the right side of the plurality of cooling rollers and can rotate circumferentially. The motor is connected to one end of the winding roller.

[0021] The end of the cooled tarpaulin is connected to the winding roller, and the motor drives the winding roller to rotate circumferentially, so that the winding roller pulls the cooled and shaped tarpaulin into the winding process and rolls up the tarpaulin neatly and orderly, which is convenient for subsequent storage, transportation and further processing.

[0022] In the above-mentioned laminating device for producing composite tarpaulin, the outer peripheral surface of the coating roller is uniformly covered with bristles.

[0023] The setting of the bristles enables the coating roller to apply the glue on the surface of the base film and the surface film more delicately and evenly during the rolling process, so that the thickness of the glue coating is consistent, so as to ensure the bonding effect and improve the bonding strength, thereby improving the overall performance of the tarpaulin.

[0024] In the above-mentioned laminating device for composite tarpaulin production, the outer peripheral surfaces of the leveling roller and the cooling roller are smooth surfaces, and the outer peripheral surfaces of the unwinding roller, the conveying roller, the pressing roller and the winding roller are frosted surfaces.

[0025] Leveling rollers and cooling rollers with smooth surfaces can make the material smoother and prevent the surface of the material from being scratched, thereby improving the efficiency of leveling and cooling and shaping. Unwinding rollers, conveying rollers, pressing rollers and winding rollers with frosted surfaces can provide greater friction, which helps to maintain stable material tension during the unwinding, conveying, pressing and winding processes, enhance the grip on the material, prevent the material from slipping or loosening, thereby improving the stability of unwinding and conveying, the uniformity of pressing and the tightness of winding.

[0026] Compared with the prior art, the laminating device for composite tarpaulin production can complete the double-sided laminating process at one time without pausing for turning over, effectively shortening the production cycle and improving production efficiency; the two symmetrically arranged pressing rollers ensure that the base film and mesh cloth, as well as the surface film and mesh cloth are heated and stressed evenly during the hot pressing process, thereby improving the stability and consistency of the double-sided laminating effect; at the same time, the pretreatment of the material, uniform glue coating and rapid cooling and shaping also improve the bonding effect of the material, thereby improving the overall production quality, and the resulting tarpaulin has high strength, high flatness and is not easy to deform.
