Description

A six-roller coating mechanism and compound machine thereof Technical Field

[0001] The utility model relates to the technical field of packaging equipment, in particular to a six-roller coating mechanism and a composite machine thereof. Background Art

[0002] In the field of packaging technology, compounding machines are essential equipment. Compounding machines are equipment used to compound two or more layers of materials. In traditional compounding machines, most of the materials are coated on one base and then transferred to another base for compounding. With the development of technology and the demand for compact equipment, the industry has gradually developed and designed compounding bases that can perform coating and compounding on the same base at the same time, such as the scheme disclosed in "A Compounding Machine and Compounding Method" applied by the same applicant in application number 201310326676.5. The compounding machine discloses a first base, on which a coating component and a compounding component are provided, thereby realizing coating and compounding on the same base.

[0003] This type of coating assembly usually adopts a five-roller coating assembly. With the expansion of packaging needs and based on the feedback of problems in the production of the five-roller coating assembly, the same applicant provided a six-roller coating composite machine base with patent number 202120109700.X. On the six-roller coating composite machine base, the deformation of the coating rubber roller is avoided by setting a corrective roller (the coating pressure roller in this application) to solve the problems in the five-roller coating.

[0004] When using a six-roll coating assembly, the coating pressure roller is connected by a swing arm, which adjusts the coating pressure roller's pressure during coating. The coating rubber roller is fixed and rotates through contact friction with the roller. In practice, this can cause "slippage" when using low-viscosity glue, which in turn affects the amount of glue applied to the roll and the quality of the entire coating and laminating process. Therefore, a six-roll coating mechanism and its laminating machine were designed to address this problem. Utility Model Content

[0005] In response to the defects in the existing technology, the utility model provides a six-roller coating mechanism and its compounding machine, which solves the problem of uniform gluing of low-viscosity glue, directly improves the coating quality of the material roll when applying low-viscosity glue, and thus improves the compounding quality of the product.

[0006] In order to achieve the above-mentioned purpose, the utility model provides a six-roller coating mechanism, including a machine base, on which a metering roller, a transfer steel roller, a transfer rubber roller, a coating steel roller, a coating rubber roller, and a coating pressure roller are provided. The coating rubber roller is movably connected to the machine base through a linear motion mechanism so that the coating rubber roller can move linearly on the machine base.

[0007] According to the above-mentioned six-roller coating mechanism, the coating rubber roller is set as a linear movable mechanism and has an actively driven linear motion mechanism, and the coating rubber roller is located between the coating pressure roller and the coating steel rod. When the coating rubber roller moves, it will simultaneously affect the force between the coating steel roller and the coating pressure roller, and the force between the coating rubber roller and the upper and lower rollers will affect the amount of glue attached to the coating rubber roller, thereby affecting the amount of glue applied to the material roll. Therefore, the "slipping" problem can be solved by adjusting the force between the coating rubber roller and the upper and lower rollers, and the problem of the amount of glue applied with low viscosity glue can be solved.

[0008] Furthermore, the coating roller is fixedly connected to the machine base. Since the coating rubber roller can simultaneously adjust the force acting on the upper coating roller and the force acting on the lower coating steel roller, the coating roller is set as a fixed body so that it rotates in a fixed position.

[0009] Furthermore, the base has a guide portion, so that the coating rubber roller moves along the guide portion and abuts against the coating pressure roller and the coating steel roller. The guide portion includes a guide slot or a guide rail, and the coating rubber roller is installed in the guide slot or on the guide rail. The guide slot is an open structure, which facilitates the installation and removal of the coating rubber roller, making it easy to assemble.

[0010] Furthermore, the machine base near the coating rubber roller is provided with an introduction roller for inputting the material roll.

[0011] According to one aspect of the present application, when a web enters the base from the left, the transfer steel roller, coating steel roller, and coating pressure roller rotate counterclockwise, while the transfer rubber roller and coating rubber roller rotate clockwise. When the base in the present application is located to the right of the web within the overall apparatus, the web entering the base will enter from the left for coating. This dictates the rotational direction of each roller to ensure smooth web coating, as shown in Figure 1.

[0012] According to another aspect of the present application, when the roll enters the base from the right, the transfer steel roller, coating steel roller, and coating pressure roller rotate clockwise, while the corresponding transfer rubber roller and coating rubber roller rotate counterclockwise. When the base in the present application is located to the left of the roll in the overall equipment, the roll entering the base will enter the base from the right for coating. This effectively limits the rotation direction of each roller to ensure smooth coating of the roll, as shown in Figure 2. As can be seen from the above two methods, the base of the present application is highly adaptable and can be adapted to different machine models.

[0013] The present application also provides a compound machine, which includes the above-mentioned six-roller coating mechanism.

[0014] Furthermore, the compound machine includes:

[0015] The surface layer unwinding and coating seat is provided with a surface layer unwinding mechanism, a surface layer coating component and a surface layer material;

[0016] A composite winding seat is provided with a bottom unwinding mechanism, bottom material, a second composite part and a composite winding mechanism; and

[0017] The coating and laminating stand includes the six-roll coating mechanism; the stand is provided with an intermediate layer unwinding mechanism, an intermediate layer material, and a first laminating portion;

[0018] Among them, the surface layer unwinding coating seat and the six-roller coating mechanism are respectively associated with the composite machine seat.

[0019] According to the above-mentioned compounding machine, by arranging the compound winding seat in the middle, the path of the material roll compounded finished product is shortened, and on the coating compounding seat, a six-roller coating mechanism and an intermediate layer unwinding mechanism are provided, the intermediate layer material and the first compounding part, so that the path of the intermediate layer material is shortened, and the bottom layer material after coating is compounded, thereby ensuring the stability of the intermediate layer material, because the intermediate layer material may use aluminum foil material with low tearing strength in packaging; and in order to improve the quality of compounding, a newly designed six-roller coating mechanism is adopted to make its coating quality better, thereby improving the compounding quality.

[0020] Furthermore, a tension roller is provided between the six-roller coating mechanism and the first composite part.

[0021] The utility model has at least the following beneficial effects:

[0022] By connecting an active linear motion mechanism to the coating rubber roller, the coating rubber roller can move in a straight line, thereby controlling the force between the coating rubber roller, the coating pressure roller, and the coating steel rod. This solves the "slipping" problem caused by the use of low-viscosity glue, and also solves the additional problem of glue application amount, thereby improving the coating quality.

[0023] The quality of composite products is improved by adopting a new six-roller coating mechanism. BRIEF DESCRIPTION OF THE DRAWINGS
