DETAILED DESCRIPTION

[0018] To describe the technical content, structural features, achieved purpose and effect of the application in detail, the technical solutions in the embodiments of the application will be described below in conjunction with the drawings in the embodiments of the application. Obviously, the described embodiments are only a part of the embodiments of the application, rather than all of the embodiments. In the following description, for the purpose of explanation, many specific details are set forth to provide a detailed description of various exemplary embodiments or implementations of the invention. However, various exemplary embodiments may also be implemented without these specific details or in the case of one or more equivalent arrangements. In addition, various exemplary embodiments may be different, but not necessarily exclusive. For example, without departing from the inventive concept, the specific shape, structure and characteristics of the exemplary embodiment may be used or implemented in another exemplary embodiment.

[0019] In the present application, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium.

[0020] The embodiment of the present application provides a composite device for a drainage board, which is used to fully automatically composite a non-woven fabric on the surface of the drainage board. Figure 1 As shown, the composite device 100 includes: a pressing and forming mechanism 10 , a heating device 20 and an auxiliary pressing device 30 .

[0021] like Figure 1 As shown, the compacting and forming mechanism 10 comprises a conveying channel 1, an upper roller 2 rotatably arranged on the upper side of the conveying channel 1, and a lower roller 3 rotatably arranged on the lower side of the conveying channel 1, and both the upper roller 2 and the lower roller 3 extend in the transverse direction. The upper roller 2 is configured to be movable in the up-down direction; the conveying channel 1 is used for conveying the non-woven fabric and the drainage board in an up-down overlapping manner, and the upper roller 2 is connected to a pressing assembly 4 in a transmission manner, and the pressing assembly 4 is used to drive the upper roller 2 to approach the lower roller 3 to preliminarily press the non-woven fabric on the drainage board.

[0022] The heating device 20 is arranged around the lower roller 3. The heating device 20 includes a heating cover 5 and an adjusting cylinder 6 for driving the heating cover 5 to approach and move away from the lower roller 3. The heating cover 5 is used to heat the drainage board and non-woven fabric conveyed on the lower roller 3, so that the non-woven fabric can be more easily laminated on the drainage board. The adjusting cylinder 6 drives the heating cover 5 to move so that the heating cover 5 is suitable for laminating products of different thicknesses and is convenient for the product to be threaded. The curvature of the heating cover 5 is consistent with the curvature of the outer surface of the outer roller 3; Figure 2 As shown, a plurality of heating blocks 51 are arranged on the side of the heating hood 5 facing the lower roller 3. The plurality of heating blocks 51 are divided into a plurality of heating groups. The heating blocks 51 of each heating group are arranged in sequence along the transverse direction. The plurality of heating groups are arranged in sequence along the arc of the heating hood. The heating blocks 51 of two adjacent heating groups are alternately arranged in the transverse direction to avoid uneven heating of the drainage board and the non-woven fabric by the heating hood 5.

[0023] like Figure 1 As shown, a reflector 52 is also provided on the heating cover 5 , and the reflector 52 is used to keep the drainage board and the non-woven fabric heated by the heating cover 5 warm, so as to prevent the heat generated by the heating cover 5 from being attenuated.

[0024] Several heating blocks 51 are connected to a control module signal. A temperature sensor connected to the control module signal is provided on the lower roller 3. The temperature sensor is used to detect the temperature of the product in the area covered by the heating cover 5 on the lower roller 3. The control module controls the temperature of the heating block 51 based on the detection result of the temperature sensor.

[0025] The auxiliary pressing device 30 is arranged downstream of the heating device 20 in the rotation direction of the lower roller 3. After the drain board and the non-woven fabric are heated, the non-woven fabric is pressed onto the drain board, so that the non-woven fabric and the drain board are more tightly compounded. The auxiliary pressing device 30 includes a pressing roller 7 and a pressing cylinder 8 drivingly connected to the pressing roller 7. The pressing cylinder 8 is used to drive the pressing roller 7 to move back and forth in the radial direction of the lower roller 3 to approach and move away from the lower roller 3. The pressing cylinder 8 drives the pressing roller 7 to approach the lower roller 3. The pressing roller 7 cooperates with the lower roller 3 to press the non-woven fabric tightly onto the drain board.

[0026] The present application uses a heating hood to make the non-woven fabric and the drainage board more firmly bonded, and cooperates with an auxiliary pressing device to improve the bonding efficiency.

[0027] The above shows and describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present application. Without departing from the spirit and scope of the present application, the present application may have various changes and improvements, and the scope of protection claimed in the present application is defined by the attached claims, description and their equivalents.
