Description

Technical Field

[0001] This utility model relates to paper coating technology, specifically an automatic glue-cutting device for paper coating. Background Technology

[0002] Currently, there are two main types of adhesive coating methods used in the production of paper honeycomb cores: roller coating and spray coating. Both methods involve applying adhesive to the surface of the base paper, transforming it into a paper honeycomb core after subsequent processing.

[0003] However, when the glue applicator is briefly stopped, the glue sprayed from the applicator tube will solidify, and the raw paper will stick to the applicator tube. This will not only block the glue outlet of the applicator tube, but also damage the raw paper when it moves when the equipment is restarted. Utility Model Content

[0004] To address the shortcomings of the prior art, this utility model provides an automatic glue-cutting device for paper coating. By rotating the eccentric roller, the height of the paper can be adjusted, causing the paper to automatically separate from the coating tube, thereby achieving the automatic glue-cutting function.

[0005] To achieve the above technical objectives, the present invention adopts the following technical solution: an automatic glue-cutting device for paper coating, comprising a base frame, wherein a feeding roller, a glue spraying pipe and an eccentric roller are provided on the top of the base frame, the glue spraying pipe is located between the eccentric roller and the feeding roller, the paper enters from below the feeding roller, passes below the glue spraying pipe and exits from above the eccentric roller, and the eccentric roller is driven to rotate by a drive unit.

[0006] Preferably, the drive unit includes a motor, a synchronous belt, and two synchronous pulleys. The motor is fixed to the base frame, and the two synchronous pulleys are respectively sleeved on the motor output shaft and the end of the eccentric roller. The synchronous belt passes around the two synchronous pulleys in sequence and is connected end to end.

[0007] Preferably, the adhesive spray tube is provided with mounting brackets at both ends, the two mounting brackets are respectively fixed to the two ends of the mounting rod, and the mounting rod is fixed to the base frame.

[0008] Preferably, the mounting rod has a plurality of support blocks in the middle, the support blocks being used to support the middle of the glue spray tube.

[0009] In summary, this utility model achieves the following technical effects:

[0010] The automatic glue-cutting device for paper coating of this utility model uses a drive unit to drive the eccentric roller to rotate, which can adjust the height of the paper so that the paper automatically separates and contacts the coating tube, thereby realizing the functions of coating and automatic glue-cutting.

[0013] The present invention will be further described in detail below with reference to the accompanying drawings.

[0014] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0015] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0016] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0017] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0018] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0019] Example 1:

[0020] like Figure 1 As shown, an automatic glue-cutting device for paper coating includes a base frame 1. The top of the base frame 1 is provided with a feeding roller 2, a glue spraying pipe 6, and an eccentric roller 7. The glue spraying pipe 6 is located between the eccentric roller 7 and the feeding roller 2. The paper enters from below the feeding roller 2, passes below the glue spraying pipe 6, and exits from above the eccentric roller 7. The eccentric roller 7 is driven by a drive unit to rotate.

[0021] The automatic glue-cutting device for paper coating in this embodiment uses a drive unit to drive the eccentric roller 7 to rotate, which can adjust the height of the paper so that the paper can automatically separate and contact the coating tube, thereby realizing the functions of coating and automatic glue-cutting.

[0022] The drive unit includes a motor 9, a synchronous belt, and two synchronous pulleys 8. The motor 9 is fixed to the base frame 1. The two synchronous pulleys 8 are respectively sleeved on the output shaft of the motor 9 and the end of the eccentric roller 7. The synchronous belt passes around the two synchronous pulleys 8 in sequence and is connected end to end. The motor 9 is a servo motor 9. The motor 9 drives the synchronous pulleys 8 to rotate, which in turn drives the eccentric roller 7 to rotate. When the eccentric roller 7 rotates 180 degrees, the paper moves downward. At this time, the paper separates from the glue coating tube. When applying glue normally, the eccentric roller 7 only needs to continue to rotate 180 degrees for the paper to move upward. At this time, the paper contacts the glue coating tube.

[0023] The glue spray tube 6 is provided with mounting brackets 4 at both ends. The two mounting brackets 4 are fixed to the two ends of the mounting rod 3 respectively. The mounting rod 3 is fixed to the base frame 1. The mounting rod is provided with several support blocks 5 in the middle. The support blocks 5 are used to support the middle of the glue spray tube 6. The support blocks 5 are provided to prevent the glue spray tube 6 from sagging due to gravity, to ensure that the glue spray tube 6 is horizontal, so that the glue sprayed out is uniform.

[0024] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
