Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, and more specifically, it relates to a gluing mechanism for producing corrugated paperboard. Background Art

[0002] In the production process of corrugated paperboard, multiple layers of raw materials need to be glued and then laminated. Therefore, a gluing mechanism is arranged under the corrugated paper to be laminated to complete the gluing operation of the corrugated paper. A too thin glue layer will result in insufficient laminating force, while a too thick glue layer will make the formed paperboard too hard, and the glue loss will be large, resulting in poor overall effect. Based on this, the utility model proposes a gluing mechanism for corrugated paperboard production. Utility Model Content

[0012] In order to enable those skilled in the art to better understand the technical solution of the utility model, the preferred implementation scheme of the utility model is described below in conjunction with specific embodiments, but it should be understood that these descriptions are only for further illustrating the features and advantages of the utility model, rather than limiting the patent requirements of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the utility model.

[0013] The utility model is further described below in conjunction with the accompanying drawings and preferred embodiments.

[0014] Example 1

[0015] See also Figure 1 and Figure 2 As shown, the present embodiment involves a gluing mechanism for corrugated cardboard production, comprising a glue tank 1 located below the corrugated paper 100 being conveyed, a glue coating roller 2 with a roller surface close to the corrugated paper being rotatably connected in the glue tank 1, and a glue scraping assembly 200 is provided on the glue tank 1 at the output end of the glue coating roller 2 facing the corrugated paper 100. The glue scraping assembly 200 is arranged on the glue tank 1.

[0016] Furthermore, the glue containing tank 1 includes two side panels 3 which are symmetrically arranged on the left and right sides, and the glue scraping assembly 200 includes a fixed backing plate 4 and a fixed bottom plate 5 which are connected between the side panels 3. A movable bottom plate 6 which is parallel to the fixed bottom plate 5 is provided below the fixed backing plate 4. A scraper 7 which slides relatively to the fixed backing plate 4 is tightly attached to the fixed backing plate 4. The upper end of the scraper 7 has a scraper head 8 close to the corrugated paper, and the lower end is connected to the movable bottom plate 6. A guide hole 9 which extends up and down is opened on the fixed backing plate 4. A guide stud 10 which has one end connected to the scraper 7 and the other end extending out of the guide hole 9 is slidably connected in the guide hole 9. A nut 11 which is threadedly connected to the guide stud 10 and whose end face is pressed against the fixed backing plate 4 is threadedly connected. An adjusting screw 12 which has its end against the movable bottom plate 6 is threadedly connected to the fixed bottom plate 5.

[0017] In this embodiment, by rotating the adjusting screw 12 clockwise to push the movable bottom plate 6, the distance between the movable bottom plate 6 and the fixed bottom plate 5 increases, causing the scraper 7 to move downward relative to the fixed support plate 4, the distance between the scraper head 8 and the corrugated paper increases, and the glue thickness increases; by adjusting the screw 12 counterclockwise and then loosening the nut 11, the scraper 7 can be reset to restore the original glue thickness.

[0018] As the scraper 7 is used for a long time, the glue will be deposited on the scraper head 8, causing the height to increase, and the glue coating thickness will be inadvertently reduced. This change can be compensated by properly turning the adjustment screw 12 clockwise. After cleaning the glue deposited on the scraper head 8, the composite scraper 7 can be used.

[0019] Example 2

[0020] See also Figure 1 and Figure 2 As shown, the gluing mechanism for corrugated cardboard production involved in this embodiment is further configured on the basis of Embodiment 1, wherein the scraper 7 is arranged in an inclined state with the upper end away from the gluing roller 2 and the lower end close to the gluing roller 2 .

[0021] Furthermore, the scraper 7 forms an angle of 15° to 45° with the vertical plane.

[0022] In this embodiment, the scraper 7 is placed obliquely to facilitate the scraped glue to flow down along the wall and be recovered by the glue tank 1.

[0023] The gluing mechanism for corrugated board production involved in the utility model realizes the function of adjusting the gluing thickness by arranging a scraper that can control the distance close to the corrugated paper. The gluing thickness is controllable, the use is flexible and convenient, the overall function is complete, and the practicability is strong.
