Description

Technical Field

[0001] This utility model relates to the field of coating mechanism technology, specifically to a coating mechanism for a double-sided coating machine. Background Technology

[0002] Lamination is a surface finishing process after printing, also known as post-printing lamination, post-printing adhesive bonding, or post-printing film application. It refers to the process of using a laminating machine to cover the surface of printed materials with a transparent plastic film of 0.012 to 0.020 mm thickness, thus forming a paper-plastic composite product. The laminating machine is the equipment used to complete the lamination process.

[0003] Double-sided laminating machines are mechanical devices that can simultaneously laminate the upper and lower surfaces of printed materials. They typically have an upper pressure plate and a lower pressure plate. Two films pass through the lower and upper pressure plates, respectively. The printed material is placed between the two films, and the films are pressed onto the printed material by a heat-pressing mechanism of the upper and lower pressure plates. The films are then cut to form the laminated product. However, in existing double-sided laminating machines, after the films are cut, the next time the printed material is laminated, the operator needs to manually stretch the films to prevent wrinkles, which would affect the lamination effect and increase the operator's workload. Therefore, the inventor has provided a lamination mechanism for a double-sided laminating machine to solve the above problems. Utility Model Content

[0004] Technical problems to be solved

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a laminating mechanism for a double-sided laminating machine, which can effectively solve the problems in the existing technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model provides a laminating mechanism for a double-sided laminating machine, including a mounting frame. Hydraulic rods are fixed to the top and bottom of the mounting frame. The bottom output end of the hydraulic rods is fixedly connected to a pressing plate. A side groove is formed on one side wall of the mounting frame, and a mating groove is formed on the inner side wall. Angle brackets are fixed in the mating groove. Four sets of angle brackets are fixedly connected to a middle plate. A laminating assembly is fixed to the bottom of the pressing plate. The laminating assembly includes a laminating frame and a laminating roller fixed within the laminating frame. The four corners of the middle plate are... The end is provided with a tensioning assembly, which includes a deflection rod, a pressure roller, and a servo motor. The output end of the servo motor is fixedly connected to the middle part of the pressure roller. The pressure roller is sleeved on one end of the deflection rod. The middle part of the deflection rod is fixedly connected to a lifting rod, and the lifting rod passes through a positioning rod. The inner side of the positioning rod is fixedly connected to a side groove. The top end of the lifting rod is fixedly connected to a positioning plate. The other end of the positioning plate is fixedly connected to the top output end of a micro cylinder. The bottom of the micro cylinder is fixed to the top end of the positioning rod.

[0008] Furthermore, the four corners of the middle plate extend outwards, and an inner groove is formed in the middle of the middle plate, the size of which is larger than the size of the film-coating frame.

[0009] Furthermore, multiple sets of the coating rollers are arranged in an equidistant array within the coating frame, and the coating rollers protrude beyond the outer side of the coating frame.

[0010] Furthermore, an L-shaped plate is fixed to one side of the servo motor, the L-shaped plate is fixedly connected to the deflection rod, and the end of the deflection rod is movably sleeved on the mounting bracket via a pin.

[0011] Furthermore, a spring is fitted between the bottom end of the positioning rod and the top end of the deflection rod.

[0012] Furthermore, the bottom end of the pressure roller is connected to the top end of the four corner extensions of the middle plate.

[0013] The technical solution provided by this utility model has the following advantages compared with the known public technology:

[0014] This invention features a structure with two sets of hydraulic rods and a coating assembly. The user can drive the pressing plate and coating frame via the hydraulic rods. The structure to be coated is sandwiched between the two sets of coatings. As the two sets of coatings enter, they can extend towards the center. The structure to be coated moves along the center of the middle plate and is supported by the coating roller at the bottom. The top coating can be stretched by the stretching assembly. During this process, the servo motor drives the pressure roller to rotate outwards. Therefore, before contacting the structure, the top coating can unfold to its four corners, reaching a certain size. This improves the contact effect with the material and avoids the need for manual tensioning of the film, preventing wrinkles and ensuring a better coating effect.

[0015] In this device, the end of the deflection rod is movably sleeved with the pin and the mounting frame, while the positioning rod at the top is fixedly connected to the mounting frame. Therefore, the miniature cylinder structure at the top of the positioning rod can be driven to the top via the positioning plate-lifting rod, thereby deflecting the deflection rod and its front end structure to the top. This allows the pressure roller to be lifted to a certain height along with the middle plate, facilitating the adjustment of coatings of different thicknesses. The contact force between the pressure roller and the coating can also be adjusted as needed, thereby adjusting the stretching length of the coating and improving the contact effect with the bottom material.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0024] The present invention will be further described below with reference to the embodiments.

[0025] Example: A laminating mechanism of a double-sided laminating machine, as shown in the attached figure. Figure 1 -Appendix Figure 5 The system includes a mounting frame 1, with hydraulic rods 2 fixed to its top and bottom. The bottom output end of the hydraulic rods 2 is fixedly connected to a pressing plate 21. A side groove 11 is formed on one side wall of the mounting frame 1, and a mating groove is formed on its inner side wall. Angle brackets 12 are fixed in the mating grooves. Four sets of angle brackets 12 are fixedly connected to a middle plate 3. A film coating assembly 4 is fixed to the bottom of the pressing plate 21. The film coating assembly 4 includes a film coating frame 41 and a film coating roller 42 fixed in the film coating frame 41. Tensioning assemblies 5 are provided at the four corners of the middle plate 3. The device includes a deflection rod 51, a pressure roller 53, and a servo motor 55. The output end of the servo motor 55 is fixedly connected to the middle part of the pressure roller 53. The pressure roller 53 is sleeved on one end of the deflection rod 51. The middle part of the deflection rod 51 is fixedly connected to the lifting rod 56, and the lifting rod 56 passes through the positioning rod 57. The inner side of the positioning rod 57 is fixedly connected to the side groove 11. The top end of the lifting rod 56 is fixedly connected to the positioning plate 59. The other end of the positioning plate 59 is fixedly connected to the top output end of the micro cylinder 58. The bottom of the micro cylinder 58 is fixed to the top end of the positioning rod 57.

[0026] The four corners of the middle plate 3 extend outwards, and an inner groove 31 is provided in the middle of the middle plate 3. The size of the inner groove 31 is larger than the size of the film-coating frame 41. By setting up two sets of hydraulic rods 2 and film-coating assembly 4, the user can drive the pressing plate 21-film-coating frame 41 through the hydraulic rods 2. The structure to be coated is sandwiched between the two sets of film, so when the two sets of film enter, it can be pushed towards the middle. The structure to be coated moves along the middle of the middle plate 3 and is supported by the film-coating roller 42 at the bottom. The film at the top can be stretched by the stretching assembly 5. During this process, the servo motor 55 can drive the pressure roller 53 to rotate outwards. Therefore, the film at the top can be unfolded to the four corners before contacting the structure. The film at the top can be unfolded to a certain size. Therefore, when the film at the top contacts the material, it can improve the contact effect with the material and avoid the problem of manual tensioning of the film by the staff, which can prevent the film from wrinkling and affect the coating effect.

[0027] Multiple sets of coating rollers 42 are arranged in an equidistant array within the coating frame 41, and the coating rollers 42 protrude from the outer side of the coating frame 41; an L-shaped plate 54 is fixed to one side of the servo motor 55, and the L-shaped plate 54 is fixedly connected to the deflection rod 51, the end of the deflection rod 51 being movably sleeved on the mounting frame 1 via a pin 52; a spring is sleeved between the bottom end of the positioning rod 57 and the top end of the deflection rod 51; the bottom end of the pressure roller 53 is connected to the top end of the four corner extensions of the middle plate 3; in this device, the end of the deflection rod 51 and the pin 52 are connected to the mounting frame. 1. The device is set up in an active manner. The positioning rod 57 at the top is fixedly connected to the mounting frame 1. Therefore, the micro cylinder 58 structure at the top of the positioning rod 57 can be driven to the top through the positioning plate 59 and the lifting rod 56. This will deflect the deflection rod 51 and its front end structure to the top, so that the pressure roller 53 can be lifted to a certain height with the middle plate 3 in the middle. This makes it easy to adjust the film thickness. The contact force between the pressure roller 53 and the film can also be adjusted as needed, thereby adjusting the stretching length of the film and improving the contact effect with the bottom material.

[0028] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
