Description

Technical Field

[0001] The utility model relates to the technical field of film coating equipment, in particular to a rapid plastic protective film coating device. Background Art

[0002] Protective film is a kind of membrane material that has the function of protecting the surface of other materials. It is mainly used for the surface protection of various products with high requirements on surface conditions to prevent scratches, pollution and wear during transportation, processing, storage, installation and use, so as to keep the items in good appearance and improve the grade and yield of products. At the same time, plastic film plays a role in moisture-proof, waterproof, anti-fouling, wear-resistant, fold-resistant, chemical corrosion-resistant and other protective functions, and is widely used in various products. When the protective film needs to be attached to the product, the laminating equipment will be used for the laminating operation.

[0003] The laminating equipment in the prior art is not suitable for laminating paper or plastic products, and its roller cannot be adjusted in height according to the thickness of the product. In order to solve the above technical problems, many related patents have been proposed in the prior art, including a Chinese patent with application number 202221241902.0, authorization publication number CN217704714U, and invention name "A universal laminating device for protective film". The above patent discloses a universal laminating device for protective film, including a production platform, a U-shaped support frame, a lifting hydraulic cylinder, a laminating roller, a driving motor, a support roller, a heating and temperature control roller, an auxiliary gear lever, an extrusion drive ring and a support frame. The support frame is arranged on the top of the production platform, and the U-shaped support frame is located at the inner top wall of the support frame.

[0004] In the above patent, the U-shaped support frame and the coating roller can be controlled to rise and fall by the hydraulic cylinder, so as to control the adjustment of the roller shaft height. The running drive motor can drive the coating roller, so that the device can adjust the roller shaft height according to the thickness of the desired coated product. However, in actual use, since each workpiece needs to be coated, the film needs to be cut after each workpiece coating. At this time, only a separate drive source can be used to drive the cutting knife to slide down for cutting, and then another drive source is used to drive the next workpiece to a predetermined position for another coating operation. The two need to be controlled by a separate drive source, which will increase the production cost and require more complex program control, which is not convenient for later maintenance and has certain shortcomings.

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-8 The utility model provides a technical solution: a rapid plastic protective film coating device, comprising a frame 1 and a mounting frame 2 fixedly connected to the frame 1, a bearing roller 3 is arranged on the mounting frame 2, a protective film body 4 is wound on the bearing roller 3, and a coating member is arranged between the mounting frame 2 and the protective film body 4; a bearing plate 9 for mounting a workpiece 10 is slidably connected to the frame 1, and a driving mechanism for driving the bearing plate 9 to slide horizontally is arranged on the frame 1; a cutting mechanism is vertically slidably connected to the mounting frame 2, and an intermittent linkage mechanism is arranged between the driving mechanism and the cutting mechanism; during the stroke in which the driving mechanism drives the bearing plate 9 to slide horizontally, the cutting mechanism is driven to reciprocate vertically through the intermittent linkage mechanism to cut the protective film coated on the workpiece 10.

[0029] Specifically, the rapid plastic protective film coating device includes a frame 1 and a mounting frame 2 fixedly connected to the frame 1. During use, multiple groups of support frames are arranged on the bottom of the frame 1, and an anti-slip pad is arranged on the bottom of each support member to improve the stability of the entire coating device during operation and meet the working impact. The mounting frame 2 is provided with a bearing roller 3, and a protective film body 4 is wound on the bearing roller 3 to facilitate the coating operation of the workpiece 10. A coating member is arranged between the mounting frame 2 and the protective film body 4 for coating the workpiece 10. A bearing plate 9 for mounting the workpiece 10 is slidably connected to the frame 1 to facilitate the coating of the workpiece 10. A driving mechanism for driving the bearing plate 9 to slide horizontally is arranged on the frame 1 to facilitate the subsequent coating operation. At the same time, a cutting mechanism is vertically slidably connected to the mounting frame 2, and an intermittent linkage mechanism is provided between the driving mechanism and the cutting mechanism, that is, during the working process, when the driving mechanism drives the carrying plate 9 to slide horizontally, it will drive the cutting mechanism to slide vertically downward to perform the cutting operation, and then it can be reset upward, which greatly improves the working efficiency of the film coating device. When the driving mechanism drives the carrying plate 9 to slide horizontally, the intermittent linkage mechanism drives the cutting mechanism to reciprocate vertically to perform the cutting operation on the protective film after the workpiece 10 is coated. Specifically, in actual use, the workpiece 10 is first mounted on the supporting plate 9, and then the supporting plate 9 is driven to slide horizontally by the driving mechanism. After the supporting plate 9 slides to a predetermined position, the workpiece 10 will be coated by the coating member. During this stroke, the cutting mechanism will be driven to slide downward by the intermittent linkage mechanism to cut the protective film body 4. After the cutting is completed, the cutting mechanism will slide upward without affecting the sliding of the supporting plate 9. As the supporting plate 9 continues to slide, the cutting mechanism will be driven to slide back and forth through the intermittent linkage mechanism. Therefore, there is no need for a separate driving source to control the sliding of the cutting mechanism, which not only saves production costs, but also facilitates later maintenance. The operation is simple and convenient, and the use effect is better.

[0030] In the embodiment provided by the utility model, the cutting mechanism includes a carrier frame 7 vertically slidably connected to the mounting frame 2, a cutting knife 8 is arranged on the bottom of the carrier frame 7, and a limiting member is arranged between the carrier frame 7 and the mounting frame 2, so that during use, the cutting knife 8 will slide downward during the downward sliding stroke of the carrier frame 7 to cut the protective film body 4. At the same time, the limiting member is arranged to improve the stability of the entire cutting mechanism during the cutting operation.

[0031] In the embodiment provided by the utility model, the limiting member includes a limiting block fixedly connected to the supporting frame 7, a limiting groove matched with the limiting block is opened on the mounting frame 2, and the limiting block is slidably connected in the limiting groove, so the use effect is better.

[0032] In the embodiment provided by the utility model, the driving mechanism includes a driving screw 11 rotatably connected to the frame 1, a driving block 12 is fixedly connected to the bottom of the carrier plate 9, and the driving block 12 is threadedly connected to the driving screw 11; a servo motor 13 is installed on the frame 1, and the servo is coaxially connected to the driving screw 11 through a coupling. Therefore, during use, when the servo motor 13 rotates, it will rotate through the driving screw 11, and drive the driving block 12 to slide horizontally through the driving screw 11, and then drive the carrier plate 9 to slide horizontally, meeting the working needs.

[0033] In the embodiment provided by the utility model, the intermittent linkage mechanism includes a connecting shaft 23 rotatably connected to the mounting frame 2, an intermittent gear 15 is arranged on the connecting shaft 23, a driving rack 14 is fixedly connected to the bearing plate 9, and the intermittent gear 15 is intermittently meshed with the driving rack 14; and multiple groups of return springs 16 are arranged between the bearing plate 9 and the mounting frame 2; the driving screw 11 and the connecting shaft 23 are connected by a transmission member. The transmission member includes a linkage rod 17 rotatably connected to the frame 1 and a transmission rod 18 rotatably connected to the mounting frame 2, the transmission rod 18 and the connecting shaft 23 are connected by a transmission gear set 21, the transmission rod 18 and the linkage rod 17 are connected by a second synchronous member 20; the linkage rod 17 and the driving screw 11 are connected by a first synchronous member 19. Therefore, when the driving screw 11 rotates, the linkage rod 17 is driven to rotate through the first synchronous member 19, and the linkage rod 17 rotates and drives the transmission rod 18 to rotate through the second synchronous member 20. When the transmission rod 18 rotates, the intermittent gear 15 is driven to rotate through the transmission gear set 21. When the intermittent gear 15 is engaged with the driving rack 14, it drives the supporting plate 9 to slide downward through the driving rack 14, and then drives the cutting knife 8 to slide downward for cutting. When the intermittent gear 15 is not engaged with the driving rack 14, the elastic force of the reset spring 16 restores the elastic deformation and drives the supporting plate 9 to reset upward. The cycle is repeated to meet the work needs. The first synchronous member 19 and the second synchronous member 20 are both prior art, and their structures and working principles are not repeated here. At the same time, the transmission gear set 21 is composed of two bevel gears to change the transmission direction.

[0034] In the embodiment provided by the utility model, the coating member includes a pressure roller 6 rotatably connected to the mounting frame 2. When the workpiece 10 passes the bottom of the pressure roller 6, the pressure roller 6 drives the protective film body 4 to abut against the workpiece 10, facilitating the coating operation.
