Description

Technical Field

[0001] This application relates to the field of artificial leather production technology, and in particular to bonding equipment for artificial leather production. Background Technology

[0002] Artificial leather is a plastic product that resembles leather in appearance and feel and can be used as a substitute. It is usually made by coating a fabric base with synthetic resins and various plastic additives; or by covering the base surface with other film layers.

[0003] The published patent document CN221067419U discloses a fully automatic bonding device for artificial leather processing. The technical solution includes a base, side plates, and a top plate. A first guide roller is rotatably mounted on one side between the side plates, and a second guide roller and a leather bonding pressure roller are rotatably mounted on the other side between the side plates. There are two of each of the second guide roller and leather bonding pressure roller. This invention, by setting up a first guide roller, a second guide roller, a leather bonding pressure roller, and a collecting winding roller, allows leather to pass through the bottom of the first guide roller via a winding roller on one side, then pass together with composite fabric on the other side between the second guide rollers, and finally between the leather bonding pressure rollers. A motor drives the first guide roller to rotate and transport the leather, while the motor drives the leather bonding pressure roller to rotate, causing the leather bonding pressure roller to continuously bond and squeeze the leather and composite fabric. The collecting winding roller collects the bonded leather, thus improving the leather bonding efficiency.

[0004] In actual use, the above device has a fixed position for the two sets of leather bonding rollers. When bonding surface layers and base layers of different thicknesses, the distance between the two sets of bonding rollers cannot be flexibly adjusted, resulting in poor bonding effect and affecting the production quality of artificial leather. Therefore, this application provides bonding equipment for artificial leather production. Utility Model Content

[0005] In view of the shortcomings of the prior art, this application provides a bonding equipment for the production of artificial leather, which overcomes the shortcomings of the prior art and aims to solve the problem that in the actual use of the above device, since the positions of the two sets of leather bonding rollers are fixed, the distance between the two sets of bonding rollers cannot be flexibly adjusted when bonding surface layers and base layers of different thicknesses, resulting in poor bonding effect and thus affecting the production quality of artificial leather.

[0006] To achieve the above objectives, this application provides the following technical solution: a bonding equipment for artificial leather production, comprising a housing, wherein a surface layer conveying roller and a base layer conveying roller are rotatably connected inside the housing, and the surface layer conveying roller and the base layer conveying roller are respectively located at the openings on both sides of the housing; a glue spraying mechanism is provided below the surface layer conveying roller; two sets of bonding rollers are slidably connected inside the housing; a spacing adjustment mechanism is provided at the connection between the two sets of bonding rollers and the housing; the spacing adjustment mechanism includes a reciprocating motor, which is fixedly installed inside the housing; a double threaded rod is fixedly installed at the output end of the reciprocating motor; two sets of moving blocks are threadedly connected to the outer surface of the double threaded rod; a connecting block is fixedly installed on the side of the moving block near the bonding roller; a rotating seat is fixedly installed on one side of the connecting block; the bonding roller is rotatably connected to the rotating seat; a collecting and winding roller is rotatably connected inside the housing above the surface layer conveying roller; and an electric heating dryer is fixedly installed inside the housing on one side of the collecting and winding roller.

[0007] By adopting the above technical solution, the surface layer is conveyed by the surface layer conveying roller, and the glue spraying mechanism automatically sprays glue onto the surface layer. The base layer is conveyed by the base layer conveying roller. The surface layer and the base layer are conveyed to the two sets of bonding rollers for extrusion bonding. Then, the bonded artificial leather is dried by an electric heating dryer. Finally, it is collected by a collecting winding roller. According to the production thickness requirements of the artificial leather, a reciprocating motor is started to drive the double threaded rod to rotate. Since the two sets of threads on the surface of the double threaded rod are opposite threads, the two sets of moving blocks move closer or further apart under the action of the two sets of opposite threads on the surface of the double threaded rod. This allows the two sets of bonding rollers to provide appropriate extrusion force for surface layers and base layers of different thicknesses. The spacing between the two sets of bonding rollers is flexibly adjusted by the spacing adjustment mechanism, ensuring the bonding effect for artificial leather of different thicknesses and improving the production quality of artificial leather of different thicknesses.

[0008] As a preferred embodiment of this application, the adhesive spraying mechanism includes an adhesive storage box, which is fixedly installed inside the housing below the surface layer conveying roller. Three sets of brackets are fixedly installed at the top of the adhesive storage box, and a dispensing pipe is fixedly installed at the top of the three sets of brackets. Several sets of atomizing nozzles are fixedly installed on the side of the dispensing pipe near the surface layer conveying roller. A material pump is fixedly installed at the bottom of the adhesive storage box, and a glue delivery pipe is fixedly installed between the discharge end of the material pump and the dispensing pipe.

[0009] By adopting the above technical solution, when the surface layer is continuously conveyed by the surface layer conveying roller, the material pump is started simultaneously. The material pump extracts the adhesive from the adhesive storage box and conveys it to the dispensing pipe. It is then evenly sprayed onto the surface layer through several sets of atomizing nozzles, which is beneficial to the uniformity of the adhesive on the surface layer, improves the uniformity of the bonding effect, and improves product quality.

[0010] As a preferred technical solution of this application, the inner wall of the chassis is provided with a storage slot that matches the spacing adjustment mechanism, and the spacing adjustment mechanism is located in the storage slot.

[0011] By adopting the above technical solution, the spacing adjustment mechanism is stored in the storage slot, which does not occupy the working environment inside the chassis and is conducive to the rational use of space inside the chassis.

[0012] As a preferred technical solution of this application, a wear-resistant layer is fixedly installed on the outer surface of the bonding roller.

[0013] By adopting the above technical solution, the wear resistance of the two sets of surface layer conveyor rollers is improved through the wear-resistant layer, which helps to extend the service life of the bonding rollers and reduce maintenance costs.

[0014] As a preferred embodiment of this application, a pressure sensor is fixedly installed in the middle of the bonding roller, a controller is fixedly installed on the outer surface of the machine housing, the pressure sensor is electrically connected to the controller, and the controller is electrically connected to the control terminal of the reciprocating motor.

[0015] By adopting the above technical solution, two sets of pressure sensors detect the extrusion pressure of the two sets of bonding rollers on the surface layer and the base layer in real time. The controller automatically starts the reciprocating motor according to the preset value and adjusts the distance between the two sets of bonding rollers as needed, so that the surface layer and the base layer always maintain a suitable extrusion pressure during the bonding process, thereby improving the intelligence level of the device.

[0016] As a preferred technical solution of this application, a guide block is fixedly installed at the bottom of the movable block, a guide rail is fixedly installed in the storage groove, and the guide block is slidably connected to the sliding end of the guide rail.

[0017] By adopting the above technical solution, the moving block drives the guide block to slide within the guide rail during the movement process, which improves the support effect and guiding function of the moving block and is conducive to the stability of the moving block during movement.

[0018] As a preferred technical solution of this application, a recycling tray is fixedly installed on the top of the adhesive storage box on one side of several sets of brackets, a discharge pipe is fixedly installed on the bottom of the recycling tray, and an opening and closing valve is fixedly installed inside the discharge pipe.

[0019] By adopting the above technical solution, the adhesive that falls off the atomizing nozzle is collected by the recovery disc, and the opening and closing of the discharge pipe is controlled by the on / off valve to discharge the adhesive collected in the recovery disc, which is beneficial to the maintenance of the working environment.

[0020] As a preferred technical solution of this application, a guide roller is rotatably connected inside the chassis between the surface layer conveying roller and the bonding roller, and a double guide roller is rotatably connected inside the chassis between the bonding roller and the collecting winding roller.

[0021] By adopting the above technical solution, the surface layer is guided to the bonding roller by the guide roller. After the surface layer and the base layer are bonded together by the bonding roller, they enter the middle of the double guide roller, which guides them to the collecting and winding roller. This facilitates the smooth and stable passage of the surface layer and the base layer through the machine casing.

[0022] The beneficial effects of this application are: The surface layer is conveyed by a surface layer conveyor roller, and an adhesive spraying mechanism automatically sprays adhesive onto the surface layer. The base layer is conveyed by a base layer conveyor roller. The surface layer and base layer are conveyed to two sets of bonding rollers for compression bonding. Then, an electric heating dryer dries the bonded artificial leather, and finally, a collecting winding roller collects it. According to the required thickness of the artificial leather, a reciprocating motor drives a double-threaded rod to rotate. Because the two sets of threads on the surface of the double-threaded rod are opposite threads, the two sets of moving blocks move closer or further apart under the action of the two sets of opposite threads on the surface of the double-threaded rod. This allows the two sets of bonding rollers to provide appropriate compression force for surface layers and base layers of different thicknesses. The spacing between the two sets of bonding rollers is flexibly adjusted by a spacing adjustment mechanism, ensuring the bonding effect for artificial leather of different thicknesses and improving the production quality of artificial leather of different thicknesses.

[0023] As the surface layer is continuously conveyed by the surface layer conveying roller, the extraction pump is started simultaneously. The extraction pump extracts the adhesive from the adhesive storage box and conveys it to the dispensing pipe. It is then evenly sprayed onto the surface layer through several sets of atomizing nozzles, which helps to improve the uniformity of the adhesive on the surface layer, enhances the bonding effect, and improves product quality.
