Description

Technical Field

[0001] The utility model relates to the field of film laminating equipment, in particular to a downward pressing laminating mechanism. Background Art

[0002] A laminator is a device that applies coatings to products. Usually, the products to be coated are divided into flat products and three-dimensional products. When coating flat products, only one side needs to be coated, and when coating three-dimensional products, it is usually necessary to coat multiple sides of the product. When laminating three-dimensional products, a pre-coating method is usually adopted, that is, the paint is first coated on a film tape, and then the paint is transferred to the product by hot pressing.

[0003] In the process of transferring the paint from the film tape to the product, the degree of adhesion between the film tape and the product will affect the quality of the coating. If the degree of adhesion between the film tape and the product is not high, there will be problems such as uneven coating and insufficient firmness, which will ultimately affect the quality of the finished product. Targeted improvements need to be made to the adhesion problem. Utility Model Content

[0004] The utility model aims to provide a downward pressing laminating mechanism, which has the advantage of making the film strip pre-coated with paint and the product to be laminar have better lamination degree, thus ensuring the laminating quality.

[0005] In order to achieve the above-mentioned purpose and other related purposes, the utility model provides the following technical solutions: a downward pressing laminating mechanism, comprising:

[0006] A mounting base for mounting the product to be laminated;

[0007] A rotary drive member for driving the mounting seat to rotate so as to drive the product to be coated to rotate;

[0008] A support assembly for holding a film strip pre-coated with paint and driving the film strip to move in a directional manner along its length direction;

[0009] A hot pressing roller connected to an external energy supply device and having a built-in heating structure;

[0010] Applying force to the hot pressing roller so that the hot pressing roller presses the film strip onto the product to be coated, and transfers the coating pre-coated on the film strip to the pressure supply part of the product to be coated in a hot pressing manner; and

[0011] The first compliant roller and the second compliant roller are respectively arranged on both sides of the hot pressing roller, and are used to squeeze and bend the film strip toward the side of the product to be coated so that the film strip covers the product to be coated.

[0012] Through the above technical scheme, the film strip pre-coated with paint is mounted on the supporting component, and the hot pressing roller presses the film strip onto the product to be coated after heating. Then, the rotating driving member drives the mounting seat to rotate and then drives the product to be coated to rotate, and the supporting component synchronously drives the film strip to move in a directional manner. Under the continuous pressure of the hot pressing roller, the paint pre-coated on the film strip is transferred to the product. In this process, the first conforming roller and the second conforming roller squeeze the film strip to bend the film strip toward the product to be coated, so that the film strip covers the product to be coated, and the part of the film strip in contact with the hot pressing roller continues to conform to the product to be coated, so that the film strip pre-coated with paint and the product to be coated have a better fit, so that the paint is evenly transferred to the product, thereby ensuring the coating quality.

[0013] In one embodiment of the present invention, the support assembly includes:

[0014] A mounting rod for holding a film strip roll; a receiving drum for recovering waste film strips after hot pressing; and a recovery drive member for driving the receiving drum to rotate so that the waste film strips are wound around the receiving drum.

[0015] Through the above technical solution, the roll of the film tape is installed on the installation rod, and the film tape is finally wound on the receiving drum after being led out. The receiving drum is used to recycle the discarded film tape after lamination.

[0016] In one embodiment of the utility model, the support assembly also includes at least two pressure rollers. After the film belt is led out from the mounting rod, it passes through the pressure roller, the first conforming roller, the hot pressing roller and the second conforming roller in sequence, and is finally recovered in the receiving drum. The pressure roller squeezes the film belt to tighten the film belt and maintain the tension of the film belt when the recovery drive drives the receiving drum to rotate.

[0017] Through the above technical scheme, the pressure roller applies pressure to the film tape. When the recovery drive drives the receiving drum to rotate so that the film tape is wound around the receiving drum, the force applied by the receiving drum to the film tape needs to be greater than the friction force of the pressure roller's rotation in order to drive the film tape. The film tape between the receiving drum and the pressure roller will be subject to tension, causing the film tape between the receiving drum and the pressure roller to move along a specific route, thereby enhancing the stability of the equipment operation.

[0018] In one embodiment of the utility model, a pair of limit blocks with adjustable spacing are respectively provided on the first conforming roller and the second conforming roller, and the limit blocks abut against the side edges of the film belt to limit the moving direction of the film belt.

[0019] Through the above technical solution, the limit block positions the film strip laterally, thereby limiting the moving direction of the film strip and ensuring that the film strip can cover the pre-set coating position.

[0020] In one embodiment of the present invention, the pressure supply assembly includes:

[0021] a pressure driving member for driving the sliding frame to slide in a linear direction; and an elastic member connecting the hot pressing roller and the sliding frame, which elastically deforms when the hot pressing roller is pressed to apply a reverse force to the hot pressing roller.

[0022] Through the above technical solution, the pressure driving member drives the sliding frame to move toward the direction of the product to be coated, and then drives the hot pressing roller to move toward the direction of the product to be coated. When the hot pressing roller is blocked by the product to be coated and cannot continue to slide, the hot pressing roller squeezes the elastic member, and the elastic member applies a force to the hot pressing roller directed toward the product to be coated to perform hot pressing.

[0023] As described above, the downward pressing laminating mechanism of the utility model has the following beneficial effects:

[0024] The film strip pre-coated with paint is mounted on the supporting component, and the hot pressing roller presses the film strip onto the product to be coated after heating. Then the rotating driving member drives the mounting seat to rotate and then drives the product to be coated to rotate, and the supporting component synchronously drives the film strip to move in a directional manner. Under the continuous pressure of the hot pressing roller, the paint pre-coated on the film strip is transferred to the product. In this process, the first conforming roller and the second conforming roller squeeze the film strip to bend the film strip toward the product to be coated, so that the film strip covers the product to be coated, and the part of the film strip in contact with the hot pressing roller continues to conform to the product to be coated, so that the film strip pre-coated with paint and the product to be coated have a better fit, so that the paint is evenly transferred to the product to ensure the coating quality.
