Description

Technical Field

[0001] This utility model relates to the field of decorative film printing technology, specifically to a water-based printing device for decorative films. Background Technology

[0002] Water-based printing on decorative films is a process that uses water-based inks to print patterns on the surface of decorative films. It is mainly used for surface decoration in industries such as furniture, building materials, electronic products, and packaging. Compared with traditional solvent-based ink printing, water-based printing has advantages such as being environmentally friendly, having low VOC emissions, and being safe and non-toxic.

[0003] In the process of decorative film printing production, tubular decorative film is usually installed on a feeding rack and continuously printed by printing equipment. However, traditional feeding methods are mostly single-station methods, which means that when a roll of film is used up during the printing process, the machine needs to be stopped to disassemble and replace it with a new tubular film. This makes it impossible to achieve continuous and fast printing operations, resulting in reduced production efficiency and making it difficult to meet the needs of large-scale and high-efficiency decorative film production.

[0004] Therefore, this utility model provides a water-based printing device for decorative films. Utility Model Content

[0005] To address the problem that traditional single-station feeding methods cannot achieve continuous and rapid printing, resulting in reduced production efficiency and difficulty in meeting the needs of large-scale and high-efficiency production, the purpose of this utility model is to provide a water-based printing device for decorative films.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a water-based printing device for decorative film, comprising a feeding rack and a printing device, wherein the feeding rack is fixedly installed on one side of the printing device, and a feeding mechanism is provided on the upper part of the feeding rack for intermittently feeding the tubular decorative film thereon, the feeding mechanism comprising:

[0007] The switching assembly includes a rotating plate mounted on the upper part of the loading rack. Two sets of symmetrically distributed mounting brackets are fixedly installed on the top of the rotating plate. Each set of mounting brackets has a cavity in the middle. Bottom limit blocks are slidably attached to the lower part of each cavity. Drive rods are movably installed at both ends of each bottom limit block. Two symmetrically distributed side limit blocks are slidably attached to the upper part of each cavity. The other end of each drive rod is movably installed in the middle of one side of each side limit block. Two symmetrically distributed springs are fixedly installed at the bottom of each bottom limit block. The bottom ends of each spring are fixedly installed on the upper part of the mounting bracket. Two cylindrical decorative films are provided on the upper part of each set of mounting brackets. A drive assembly is provided at the bottom of the rotating plate.

[0008] Limiting components are installed on both sides of the feeding rack to limit the upper part of the tubular decorative film.

[0009] Preferably, the limiting component includes two driving cylinders fixedly installed on the upper part of the feeding rack, and clamping blocks are fixedly installed on the driving ends of the two driving cylinders. Two symmetrically distributed bases are fixedly installed in the middle of the feeding rack, and the bases are in contact with the lower ends of the cylindrical decorative film.

[0010] Preferably, two symmetrically distributed sliders are fixedly installed on both sides of the plurality of side end limiting blocks and bottom end limiting blocks, and the plurality of sliders are slidably locked on the upper part of the mounting frame.

[0011] Preferably, multiple evenly distributed limiting rollers are rotatably mounted on the arc-shaped surfaces of the multiple side-end limiting blocks, bottom-end limiting blocks, and clamping blocks, and the multiple limiting rollers are in contact with the outer surfaces of both ends of the cylindrical decorative film.

[0012] Preferably, each of the bottom limiting blocks has a sleeve fixedly installed at its bottom end to cooperate with the spring, and the bottom ends of the sleeves are fixedly installed in the middle of the mounting frame.

[0013] Preferably, the drive assembly includes a rotary cylinder fixedly installed in the middle of the loading rack, and the drive end of the rotary cylinder is fixedly installed in the middle of the bottom end of the rotating plate.

[0014] Compared with existing technologies, it has the following advantages:

[0015] 1. When the staff places the tubular decorative film on the mounting frame, the film's own weight will press down on the bottom limiting block. Under the action of the drive rod, the limiting blocks on both sides move relative to each other, and together with the limiting roller, they form a preliminary clamping and limiting of the two ends of the film. After the film is printed at the current station, the rotary cylinder drives the rotating plate to rotate 180° to realize the position exchange between the two stations, so that the new film can quickly enter the working position. At the same time, the used roller can be disassembled and replaced, effectively reducing the waiting time for feeding and improving the continuous operation efficiency of the printing equipment.

[0016] 2. In this application, after the new film is switched to the working position, the drive cylinder drives the clamping block to move down, and its surface limiting roller contacts the outer surfaces of both ends of the film, forming an upper and lower clamping structure with the lower base. At the same time, the side limiting block and the bottom limiting block always maintain stable positioning of the film under the action of spring force. Moreover, the rotation characteristics of the limiting roller not only avoid friction damage during film conveying, but also ensure the stability of the film position during printing, reducing printing errors caused by film offset.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 This utility model provides a technical solution: a water-based printing device for decorative film, including a feeding rack 1 and a printing device 3. The feeding rack 1 is fixedly installed on one side of the printing device 3. The upper part of the feeding rack 1 is provided with a feeding mechanism 2 for intermittently feeding the tubular decorative film 214. The feeding mechanism 2 includes:

[0025] The switching component 21 includes a rotating plate 211 disposed on the upper part of the loading rack 1. Two sets of symmetrically distributed mounting brackets 213 are fixedly installed on the top of the rotating plate 211. Each set of mounting brackets 213 has a cavity 2131 in the middle. Bottom limit blocks 215 are slidably locked on the lower part of each cavity 2131. Drive rods 217 are movably installed on both ends of each bottom limit block 215. Two symmetrically distributed side limit blocks 216 are slidably locked on the upper part of each cavity 2131. The other end of each drive rod 217 is movably installed on the middle of one side of each side limit block 216. Two symmetrically distributed springs 2191 are fixedly installed on the bottom of each bottom limit block 215. The bottom of each spring 2191 is fixedly installed on the upper part of the mounting bracket 213. Two cylindrical decorative films 214 are provided on the upper part of each set of mounting brackets 213. The bottom of the rotating plate 211 is provided with a drive component.

[0026] Limiting components 22 are provided on both sides of the feeding rack 1 to limit the upper part of its tubular decorative film 214.

[0027] The limiting component 22 includes two drive cylinders 221 fixedly installed on the upper part of the feeding rack 1. Each drive cylinder 221 has a clamping block 222 fixedly installed at its drive end. Two symmetrically distributed bases 223 are fixedly installed in the middle of the feeding rack 1. The bases 223 are in contact with the lower ends of the cylindrical decorative film 214. The drive cylinder 221 adopts the standard type of CKD cylinder from Japan, model SCA2-00-50B-70.

[0028] Two symmetrically distributed sliders 2181 are fixedly installed on both sides of the multiple side limit blocks 216 and the bottom limit block 215. The multiple sliders 2181 are slidably locked on the upper part of the mounting frame 213. The sliders 2181 have a T-shaped structure and a T-shaped groove is opened at the position of the corresponding slider 2181, which allows the sliders 2181 to slide and lock in the groove, limiting the side limit blocks 216 and ensuring that the two side limit blocks 216 can slide linearly along the groove under the transmission of the drive rod 217.

[0029] Multiple side-end limiting blocks 216, bottom-end limiting blocks 215, and clamping blocks 222 are rotatably mounted with multiple evenly distributed limiting rollers 218. The multiple limiting rollers 218 are in contact with the outer surfaces of both ends of the cylindrical decorative film 214. The limiting rollers 218 are used to limit the two ends of the cylindrical decorative film 214 to be in contact with each other, ensuring stable limiting without affecting its rotation.

[0030] Each of the bottom limit blocks 215 has a sleeve 219 fixedly installed at its bottom end to cooperate with the spring 2191. The bottom ends of the sleeves 219 are fixedly installed in the middle of the mounting bracket 213. The sleeves 219 are sleeved on the outside of the spring 2191. They are divided into an inner sleeve and an outer sleeve. The inner sleeve is slidably locked inside the outer sleeve so that it does not affect the up and down movement of the bottom limit blocks 215. At the same time, it can protect the spring 2191 and prevent the spring 2191 from being irreversibly deformed due to excessive compression or stretching.

[0031] The drive assembly includes a rotary cylinder 212 fixedly installed in the middle of the loading rack 1. The drive end of the rotary cylinder 212 is fixedly installed in the middle of the bottom end of the rotating plate 211. The rotary cylinder 212 is an Airtac rotary cylinder model HRQ7, which can interchange the positions of the two cylindrical decorative films 214 in the dual-station operation.

[0032] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0033] During operation, when feeding the tubular decorative film 214, the operator places the tubular decorative film 214 in the middle of the two mounting brackets 213. Under its own weight, it will first come into contact with the limiting roller 218 on the bottom limiting block 215, causing it to move downward. At the same time, under the transmission of its drive rod 217, the two side limiting blocks 216 that cooperate with it can move relative to each other, thereby clamping and limiting the two ends of the roller shaft of the tubular decorative film 214, thus completing the pre-feeding work.

[0034] After the decorative film is printed on the front cylindrical decorative film 214, the drive cylinder 221 moves upward to move the clamping block 222 away from both ends of the cylindrical decorative film 214. At this time, the rotary cylinder 212 starts and drives the rotary plate 211 to rotate 180°, so that the positions of the two cylindrical decorative films 214 are interchanged. At this time, the two ends of the cylindrical decorative film 214 loaded with its decorative film are located at the lower part of its clamping block 222. The drive cylinder 221 drives the clamping block 222 downward to move it down, so that multiple limiting rollers 218 contact the outer surfaces of both ends of its cylindrical decorative film 214. With the cooperation of the lower base 223, it can clamp and limit the fixed position of the film. The used rollers can be disassembled and replaced, thus forming a dual-station feeding system.
