Technical Field
[0001] The utility model relates to the field of paper film production equipment, in particular to a glue scraping device for a wet laminating machine. Background Art
[0002] Paper-film laminating machines have a long history of use. Since the acceleration of industrialization, they have become core equipment in the packaging, printing, and specialty material processing industries. They skillfully combine paper and film through advanced bonding technology, creating composite products that are both beautiful and practical. They are widely used in food packaging, pharmaceutical packaging, advertising materials, and industrial product packaging. With technological advancements, paper-film laminating machines are constantly upgraded to meet market demand for high-quality and efficient production.
[0003] Laminating rollers, while crucial in the paper-film lamination process, often face a challenge after their work is complete: the glue on their outer surface tends to solidify upon cooling, forming a residue that is difficult to clean. This not only affects the roller's subsequent performance but can also shorten the equipment's lifespan. Therefore, timely and effective cleaning of glue residue from the laminating roller's surface is crucial to maintaining equipment performance and ensuring production quality. Utility Model Content

[0021] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.
[0022] In the drawings, the same reference numerals all refer to the same components.
[0023] like Figure 1-4 As shown, the utility model provides a scraper device for a wet laminating machine, a scraper device for a wet laminating machine, comprising a composite pressure roller and a pressure roller support, characterized in that it comprises a sol component 1 and a scraper component 2, the sol component 1 is arranged on the outside of the composite pressure roller and maintains a certain distance, the scraper component 2 is arranged on the outside of the composite pressure roller and contacts the composite pressure roller, the sol component 1 is arranged at an obliquely upper position of the axis of the composite pressure roller, the scraper component 2 is arranged at an obliquely lower position of the axis of the composite pressure roller, the sol component 1 and the scraper component 2 are in an upper and lower position relationship, and when the composite pressure roller rotates, the glue attached to it first passes through the sol component 1 and then passes through the scraper component 2.
[0024] In the present invention, as the composite pressing roller rotates, the glue attached to the composite pressing roller is heated from a solidified state to a liquid state by the sol component 1 , and finally the liquid glue is scraped off by the scraping component 2 .
[0025] In an optional embodiment, the sol assembly 1 includes a sol frame 11 and a sol plate 12. The sol frame 11 is arranged at both ends of the sol plate 12 and is fixedly connected to the pressure roller support. The sol plate 12 is in the shape of an arc, and its bending angle is consistent with the curved surface of the composite pressure roller.
[0026] It should be noted that the sol frame 11 is fixed to the pressure roller support by bolts, and the bending angle of the sol plate 12 is consistent with the curved surface of the composite pressure roller, which helps to evenly heat the glue on the pressure roller support.
[0027] In an optional embodiment, the scraper assembly 2 includes a scraper frame 21 and a scraper plate 22. The scraper frame 21 is arranged on both sides of the scraper plate 22 and is fixedly connected to the pressure roller support. The scraper frame 21 and the two sides of the scraper plate 22 are connected together by bolts to form a detachable connection.
[0028] It should be noted that when the scraper plate 22 needs to perform glue scraping work, the scraper plate 22 is installed on the scraper frame 21 by tightening the bolts. When the composite pressure roller needs to perform paper-film composite work, the scraper plate 22 is removed from the scraper frame 21 by loosening the bolts to avoid interfering with the paper-film composite work.
[0029] In an optional embodiment, the scraper plate 22 is arranged at an angle, with the left end higher than the right end in a horizontal position, a baffle 23 is provided on one side of the scraper plate 22, and a glue storage assembly 3 is provided below the right end of the scraper plate 22, the glue storage assembly 3 includes a support frame 31 and a glue groove 32, one end of the support frame 31 is fixedly connected to the pressure roller support, and the other end is fixedly connected to the glue groove 32, and the opening of the glue groove 32 is located directly below the right end of the scraper plate 22.
[0030] It should be noted that the scraper plate 22, the baffle 23 and the composite pressure roller form a channel, and the inclined setting of the scraper plate 22 allows the scraped glue to flow downward along the channel under the action of gravity, and finally flows to the position where the right end of the scraper does not contact the composite pressure roller, and flows out from its notch and drips into the glue retention groove 32.
[0031] In an optional embodiment, a heating tube 13 is provided on a side of the sol plate (12) close to the composite pressing roller, and the heating tube 13 is provided in multiple layers and arranged in a zigzag manner.
[0032] It should be noted that the heating tube 13 is laid on the sol plate (12) in a zigzag manner so that the solidified glue on the composite pressing roller is heated evenly and damage to the composite pressing roller due to concentrated heat is prevented.
[0033] The working principle of the utility model is as follows: the scraper plate 22 is installed on the scraper frame 21 by bolts, so that the scraper plate 22 is attached to the outer surface of the composite pressure roller, the heating tube 13 on the sol plate (12) is started, and then the composite pressure roller is rotated. The glue on the composite pressure roller is first heated by the heating tube 13 and changes from solid to liquid. The liquid glue then contacts the scraper plate 22 along with the composite pressure roller. The scraper plate 22 scrapes the liquid glue from the composite pressure roller, and under the action of gravity, the glue passes through the channel formed by the scraper plate 22, the baffle 23 and the composite pressure roller, and finally flows to the position where the right end of the scraper does not contact the composite pressure roller, flows out from the gap and drips into the glue groove 32. The operator then cleans up the glue in the glue groove 32.
[0034] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
