Description

Technical Field

[0001] The utility model relates to the field of foam material production, in particular to a laminating machine for foam material production. Background Art

[0002] Foam materials are made by adding a blowing agent to form bubbles within the raw material, thereby reducing its density and imparting unique properties. These bubbles impart lightweight, thermal insulation, sound absorption, and shock absorption properties to the foam material. Foam materials are widely used in a variety of fields, including construction, packaging, transportation, home appliances, and sports equipment, for thermal insulation, vibration and noise reduction, and packaging protection. Due to their unique functionality and broad application prospects, foam materials play a vital role in modern industry.

[0003] After the foam material is processed, a layer of film is generally applied to the surface to protect the material and make it waterproof, overcoming the shortcomings of bubbles, wrinkles, halos, water marks, etc. caused by manual lamination. For this purpose, a laminating machine for foam material production is required.

[0004] When laminating a film on the surface of a foam material, it is usually necessary to first apply a layer of glue on the surface of the foam material, and then use a pressure roller to press the film and the foam material together. The current equipment is difficult to accurately control the area where the foam material is glued, which can easily lead to excessive glue overflow, not only causing glue waste, but also causing glue to overflow to the side area that does not require lamination, causing the side of the foam material to stick or absorb stains due to the glue, affecting the quality of the product. Therefore, a laminating machine for foam material production is proposed to solve the above problems. Utility Model Content

There are multiple groups of glue discharge through holes 13, which are evenly distributed on the outer periphery of the glue discharge roller 12. A sliding circular groove 14 is provided inside the glue discharge through hole 13. The inner side of the sliding circular groove 14 is elastically connected with a sliding circular block 16 through a limit spring 15.

The front and rear ends of the support frame 27 are fixedly connected to the inner side of the fixed bracket 7.

[0039] Working principle: When you want to evenly distribute the glue on the surface of the foam material, place the foam material on the conveyor 2, and the foam material is transported to the right by the conveyor 2. At this time, turn on the rotating motor 5, and the rotating motor 5 drives the rotating shaft 11 to rotate through the transmission assembly. The rotating shaft 11 drives the glue discharging roller 12 to rotate. The glue discharging roller 12 rotates, so that the limiting ball 18 contacts and squeezes the top surface of the foam material. At this time, the limiting ball 18 will squeeze the foam material toward the inside of the glue discharging hole 13 and squeeze the limiting spring 15. At this time, a certain gap is generated between the glue discharging hole 13 and the limiting ball 18, and the glue flows out from the inside of the glue discharging hole 13 to the surface of the foam material. When the foam material does not contact the limiting ball 18, the limiting spring 15 releases the compression, so that the limiting ball 18 blocks the glue discharging hole 13, so that the glue does not flow out, thereby ensuring that the surface of the foam material can be evenly distributed in a lattice shape with glue, and the glue will not overflow too much and cause waste. When the glue on the surface of the foaming material is to be evenly distributed, the rotating motor 5 is turned on, the rotating motor 5 will drive the rotating shaft 6 to rotate, the rotating shaft 6 will drive the driving bevel gear 19 to rotate, the driving bevel gear 19 will drive the transmission bevel gear 20 to rotate, the transmission bevel gear 20 will drive the connecting column 22 to rotate, the connecting column 22 will drive the scraper 26 to rotate through the prismatic block 25 and the limit seat 24, and at the same time the extrusion spring 23 will push the scraper 26 downward so that the scraper 26 is in close contact with the surface of the foaming material, thereby ensuring that the glue on the surface of the foaming material is evenly applied and bubbles are not easily generated during lamination.
