Description

Technical Field

[0001] This application belongs to the field of packaging paper, specifically relating to a transfer film homogenizing device and packaging paper production equipment. Background Technology

[0002] Currently, during the adhesive application process on transfer films, the adhesive is prone to forming a film due to environmental factors and its own characteristics. The reasons for this film formation include: when the adhesive remains on the surface of the adhesive application device (such as an adhesive roller or doctor blade) for an extended period, solvent evaporation causes the adhesive to thicken, gradually forming a film; a smaller percentage of cases are due to the adhesive itself forming a film after prolonged storage. This film significantly affects the uniformity of adhesive application after the transfer film passes through the adhesive application device, easily leading to uneven adhesive coating. After lamination and peeling, products are prone to quality problems such as pattern or aluminum layer peeling after aluminum layer adhesion testing or frequent friction, seriously affecting normal production. Utility Model Content

[0003] The technical problem to be solved by this application is to provide a transfer film uniform coating device and packaging paper production equipment, which reduces the influence of the adhesive on the uniformity of the transfer film and improves the uniformity of the adhesive on the transfer film.

[0004] This application provides a spin coating apparatus for a transfer film, comprising:

[0005] Support assembly;

[0006] A glue-spreading roller is rotatably mounted on a support assembly at both ends. The glue-spreading roller is attached to the back of the transfer film that has been glued during movement, and drives the glue-spreading roller to rotate to spread the glue evenly.

[0007] In some possible implementations, the support assembly includes a fixed frame, two support arms disposed on the fixed frame, and two bearing seats disposed on the two support arms respectively, with the two ends of the glue-spreading roller mounted on the two bearing seats via bearings.

[0008] In some possible implementations, the coating roller includes a smooth cylindrical structure for bonding the back side of the transfer film.

[0009] In some possible implementations, the length of the cylindrical structure is 10cm to 100cm.

[0010] In some possible implementations, the outer diameter of the cylindrical structure is 5cm to 20cm.

[0011] In some possible implementations, the support arm includes a fixed column, a linear telescopic device, and a telescopic column. The linear telescopic device drives the telescopic column to reciprocate along the fixed column to adjust the amount of extension and retraction. The bearing seat is located at the end of the telescopic column.

[0012] In some possible implementations, the linear expansion joint is disposed inside a fixed column, the expansion column is inserted into the fixed column, and both ends of the linear expansion joint are connected to the fixed column and the expansion column, respectively.

[0013] In some possible implementations, the linear telescoping device includes at least one of an electric cylinder, a pneumatic cylinder, and a hydraulic cylinder.

[0014] A packaging paper production equipment includes an adhesive applicator, a laminating device, and an adhesive leveling device as described above. The adhesive leveling device is disposed between the adhesive applicator and the laminating device. The adhesive applicator is used to apply adhesive to the transfer film, and the laminating device is used to bond the adhesive-leveled transfer film to white cardboard.

[0015] In some possible implementations, the gluing mechanism includes a gluing screen roller and a gluing pressure roller, the surface of which is covered with glue, and the transfer film passes between the gluing screen roller and the gluing pressure roller to apply the glue.

[0016] The laminating device includes a laminating steel roller and a laminating pressure roller. The transfer film, after passing through the glue-sizing device, is guided to the laminating device by a guide roller. The white cardboard and the transfer film pass together between the laminating steel roller and the laminating pressure roller.

[0017] The first aspect of this application provides a coating device for a transfer film. A fixed coating roller is applied to the already coated transfer film to evenly distribute the adhesive, addressing uneven application caused by impurities such as rubber residue during the coating process. The rotating and pressing action of the coating roller further coats the adhesive on the transfer film, effectively preventing various product adhesion issues arising from uneven adhesive application after lamination and peeling. Because this invention employs the aforementioned coating installation structure, it is simple to operate and ensures uniform adhesive application, effectively preventing various product adhesion issues caused by uneven adhesive application and guaranteeing product quality.

Detailed Implementation

[0023] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0024] The first aspect of the embodiments of this application is as follows: Figure 1-3 As shown, the present application provides a transfer film coating apparatus, including: a support assembly 110 and a coating roller 120 rotatably mounted on the support assembly 110 at both ends. The coating roller 120 is attached to the back of the transfer film 1.1 that has been coated during movement, and drives the coating roller 120 to rotate to perform coating.

[0025] Compared with the prior art, the glue-spreading device 100 provided in this application applies a fixed glue-spreading roller 120 to the glued transfer film 1.1, effectively smoothing the glue application and preventing uneven application due to impurities such as rubber sheets during the glue application process. The rotating and pressing action of the glue-spreading roller 120 further coats the glue on the transfer film 1.1, effectively avoiding various product adhesion problems caused by uneven glue application after lamination and peeling. Because this utility model adopts the above-mentioned glue-spreading installation structure, it is simple to operate during use, and its installation structure ensures uniform glue application, effectively avoiding various product adhesion problems caused by uneven glue application, and guaranteeing product quality.

[0026] In some possible implementations, the support assembly 110 includes a fixed frame 111, two support arms 112 mounted on the fixed frame 111, and two bearing seats 113 respectively mounted on the two support arms 112. The two ends of the coating roller 120 are mounted on the two bearing seats 113 via bearings. Specifically, the fixed frame 111 is bolted to the ground or other carrier. The two support arms 112 are arranged in parallel and fixed to the fixed frame 111 by screws or welding. The two bearing seats 113 allow the coating roller 120 to rotate freely. Without affecting the transport of the transfer film 1.1, the coating roller 120 applies a certain pressure to the transfer film 1.1. When the transfer film 1.1 moves, it drives the coating roller 120 to rotate, thereby achieving the function of secondary coating of adhesive.

[0027] In some possible implementations, the coating roller 120 includes a smooth cylindrical structure for bonding the back side of the transfer film 1.1. The smooth cylindrical structure allows for more uniform bonding between its various parts and the transfer film 1.1, which helps to improve the uniformity of adhesive coating.

[0028] In some possible implementations, the length of the cylindrical structure is 10cm to 100cm. Specifically, the length of the cylindrical structure is determined based on the width of the transfer membrane 1.1. It should be noted that the length of the cylindrical structure is at least 1cm greater than the width of the transfer membrane 1.1. For example, the length of the cylindrical structure can be any typical but non-limiting point value or a range between any two point values, such as 10cm, 15cm, 20cm, 50cm, 75cm, and 100cm.

[0029] In some possible implementations, the outer diameter of the cylindrical structure is 5cm to 20cm. Generally, the smaller the outer diameter of the cylindrical structure, the lighter its mass, and the easier it is for the coating roller 120 to rotate. However, the surface curvature of the coating roller 120 is also greater, which has a certain impact on the uniformity of coating. For example, the outer diameter of the cylindrical structure can be any typical but non-limiting point value or a range between any two points, such as 5cm, 10cm, 15cm, or 20cm. In these cases, it is beneficial to improve the uniformity of the coating adhesive applied to the transfer film 1.1 by the coating roller 120.

[0030] In some possible implementations, the support arm 112 includes a fixed column 1121, a linear telescopic device 1123, and a telescopic column 1122. The linear telescopic device 1123 drives the telescopic column 1122 to reciprocate along the fixed column 1121 to adjust the telescopic amount. The bearing seat 113 is located at the end of the telescopic column 1122. The two linear telescopic devices 1123 synchronously drive the telescopic column 1122 to adjust the distance between the coating roller 120 and the transfer film 1.1, as well as the force exerted by the coating roller 120 on the transfer film 1.1, thereby adjusting the coating force and improving the uniformity of the adhesive.

[0031] In some possible implementations, the linear expansion joint 1123 is housed within the fixed column 1121, and the telescopic column 1122 is inserted into the fixed column 1121. Both ends of the linear expansion joint 1123 are connected to the fixed column 1121 and the telescopic column 1122, respectively. With this configuration, the support arm 112 has an overall columnar structure, facilitating installation and providing protection for the linear expansion joint 1123.

[0032] In some possible implementations, the linear expansion joint 1123 includes at least one of an electric cylinder, a pneumatic cylinder, and a hydraulic cylinder. Among them, the electric cylinder has the advantages of small size, high precision, and fast response, which is beneficial to improving the uniformity of adhesive application by the coating roller 120.

[0033] In a second aspect of this application, a packaging paper production apparatus includes an adhesive applicator 200, a laminating device 300, and a uniform adhesive applicator 100. The uniform adhesive applicator 100 is disposed between the adhesive applicator 200 and the laminating device 300. The adhesive applicator 200 is used to apply adhesive to a transfer film 1.1, and the laminating device 300 is used to bond the uniformly adhesive-coated transfer film 1.1 to white cardboard 1.2. The uniform adhesive applicator 100 provided in the first aspect of this application improves the uniformity of adhesive application on the transfer film 1.1, thereby improving the quality of the packaging paper.

[0034] In some possible implementations, the gluing mechanism includes a gluing screen roller 201 and a gluing pressure roller 202. The surface of the gluing screen roller 201 is covered with glue. The transfer film 1.1 passes between the gluing screen roller 201 and the gluing pressure roller 202 to be coated with glue. Specifically, a portion of the gluing screen roller 201 is immersed in the glue solution 1.3 (also called glue). During the rotation of the gluing screen roller 201, the glue solution 1.3 is distributed on the surface of the gluing screen roller 201. Under the action of the transfer film 1.1 conveying device, the transfer film 1.1 passes between the gluing screen roller 201 and the gluing pressure roller 202, and the glue solution 1.3 is coated on one side of the transfer film 1.1. Under the action of the guide roller 400, it passes through the glue-splitting device 100 and subsequent processes.

[0035] In some possible implementations, the laminating device 300 includes a laminating steel roller 301 and a laminating pressure roller 302. The transfer film 1.1, after passing through the plating device 100, is guided to the laminating device 300 by the guide roller 400. The white cardboard 1.2 and the transfer film 1.1 pass together between the laminating steel roller 301 and the laminating pressure roller 302. Under the pressure of the laminating steel roller 301 and the laminating pressure roller 302, the white cardboard 1.2 and the transfer film 1.1 are tightly bonded together.
