Description

Technical Field

[0001] The utility model relates to the technical field of drainage buffer pad production, in particular to a drainage buffer pad film covering device. Background Art

[0002] Drainage pads for artificial football fields are often key components specifically designed to manage water flow and reduce water impact. The shape and design of these pads take into account the specific needs of the field surface. This helps ensure that the field surface remains flat and drains water effectively, thereby extending the life of the field and improving the quality of the game.

[0003] like Figure 1 As shown, an existing drainage buffer pad 1 has a substrate 2. In order to improve the structural strength and extend the service life, a layer of film needs to be covered on one side or both sides of the substrate 1 during production. By covering the drainage buffer pad with a layer of film, the drainage buffer pad is protected and the service life of the drainage buffer pad is increased.

[0004] However, in the prior art, when coating the drainage buffer pad, the film is mainly laid on the substrate by manual operation, and the coating efficiency is low; that is, there is a lack of an integrated device to complete the process mechanically. Utility Model Content

[0010] The coating conveying structure is used for conveying the drainage buffer pad, and is also used for coating and laminating the film material formed after melting onto the drainage buffer pad.

[0011] The above-mentioned beneficial effect is that the raw materials used for the membrane are added into the hopper, and the raw materials in the hopper continuously enter the extrusion tube, and the materials are melted by the action of the heating element. Then the extrusion roller continuously squeezes the molten material into the discharge tube, and the molten material falls into the discharge frame and falls between the two extrusion rollers from the discharge port. The molten material is sheared by the rotation of the two extrusion rollers to form a basic membrane material. At the same time, the coating conveying structure conveys the drainage buffer pad and covers the basic membrane material on the drainage buffer pad. As the drainage buffer pad is continuously conveyed, the basic membrane material is continuously coated on the drainage buffer pad, and in the process of conveying the drainage buffer pad, a layer of film is simultaneously coated on the drainage buffer pad, so that the coating efficiency is greatly improved.
