Description

Technical Field

[0001] This application belongs to the field of film application equipment, specifically a dual-cavity, opposite-side film application machine that can be automatically adjusted. Background Technology

[0002] An automatically adjustable dual-cavity, side-mounted laminating machine is a device used for automatically applying films or protective films to the surface of objects. It is widely used in industries such as electronics, glass, metal sheets, and plastic products. Side-mounted laminating machines fundamentally change the situation of low efficiency and poor film quality associated with manual laminating. The use of automatically adjustable dual-cavity, side-mounted laminating machines not only improves product quality but also increases production efficiency. Existing automatically adjustable dual-cavity, side-mounted laminating machines typically have one end of the coated roller shaft fixed and the other end suspended. This can lead to roller shaft deformation and tilting during operation, increasing laminating errors, uneven stress, and even wrinkling. This is especially problematic when the workpiece has a large film width, resulting in decreased laminating quality and seriously affecting product quality. Furthermore, while the workpiece is placed on the machine, it may have a slight tilt angle, preventing the workpiece surface from being perfectly parallel to the film. An angle often exists between the two, causing the workpiece edges to scratch the film and affecting laminating quality. Summary of the Invention

[0003] To overcome the shortcomings of the prior art, this application proposes an automatically adjustable dual-cavity opposite-side film applicator.

[0004] The technical problem solved by this application is achieved through the following technical solution: An automatically adjustable dual-cavity, side-mounted film applicator includes a chassis, a feeding limiting mechanism, and a film applicator. The feeding limiting mechanism and the film applicator are spaced apart at the upper end of the chassis, and are arranged front and rear along the feeding direction. The profile to be applicated passes through the feeding limiting mechanism and the film applicator sequentially. The feeding limiting mechanism includes a bottom feeding roller, two side feeding rollers, an upper feeding roller, and a lower feeding roller. The bottom feeding roller is limited and connected to the worktable at the upper end of the chassis. A lower feeding roller is limited and connected to the upper end of the chassis behind the bottom feeding roller. The lower feeding roller is parallel to and spaced apart from the bottom feeding roller. An upper feeding roller is arranged above the lower feeding roller. Two side feeding rollers are spaced apart on the chassis between the lower feeding roller and the bottom feeding roller. The roller shafts of the side feeding rollers are vertically arranged, and the side feeding rollers are used for the profile to pass through.

[0005] Furthermore, a sleeve seat is fixedly connected to both ends of the lower roller shaft, and the sleeve seat is fixedly connected to the machine housing. A vertical through hole is provided in each sleeve seat. A pressing column is fixedly connected to both ends of the upper roller shaft. The pressing column passes through the corresponding sleeve seat and can move up and down. The lower end of the pressing column is connected to the piston rod of the pressing cylinder. The cylinder body of the pressing cylinder is fixedly connected to the machine housing. The extension and retraction of the piston rod of the pressing cylinder can drive the pressing column to move up and down, thereby controlling the lifting and lowering of the upper roller.

[0006] Furthermore, the chassis has a cubic box structure, with a horizontal worktable at the top and height-adjustable feet at the four corners at the bottom.

[0007] Furthermore, the feed side roller is mounted on the feed side roller support plate, and a track extending in the left and right direction is fixedly connected to the upper end of the feed side roller support plate. Two sliders are slidably connected to the upper sides of the track, and a feed side roller is connected to each slider. A spacing adjustment screw is engaged with the side of the slider, and the other end of the spacing adjustment screw is limited and connected to the feed side roller support plate. Rotating the spacing adjustment screw can drive the slider to move back and forth along the track.

[0008] Furthermore, the film-applying mechanism includes a film-applying frame, a material rack, a pressure roller, and an applicator roller. Both the film-applying frame and the support plate are flat structures. The film-applying frame and the support plate are fixedly spaced on the chassis. Multiple support rods are fixedly connected between the film-applying frame and the support plate. The material rack, pressure roller, and applicator roller are connected between the film-applying frame and the support plate. The film-applying frame and the support plate have pressure rollers and applicator rollers at both ends. The upper and lower sides of the film-applying frame are provided with upper and lower material racks at intervals. Applicator rollers are arranged opposite each other in the middle of the film-applying frame. The applicator rollers are provided with film-applying material by the material racks on the corresponding sides. An opening and closing assembly is connected between the applicator rollers. Pressure rollers are provided on the sides of the applicator rollers on both the upper and lower sides. An opening and closing assembly is connected between the pressure rollers. The pressure rollers on the upper and lower sides can abut against the upper and lower end faces of the profile. Furthermore, the film-applying roller and the film-pressing roller are each connected to an opening and closing assembly separately.

[0009] Furthermore, the opening and closing assembly includes a first positioning plate, a second positioning plate, a slide table, and an opening and closing rodless cylinder. The first positioning plate and the second positioning plate are spaced apart vertically. The outer side of the first positioning plate is fixed to the film applicator frame. Two slide tables that can slide up and down are installed at intervals on the inner side of the first positioning plate. These two slide tables are used to connect the ends of the film applicator roller and the pressure roller, respectively. One end of the opening and closing rodless cylinder is connected to each slide table. The other end of the opening and closing rodless cylinder is connected to the second positioning plate. The second positioning plate is fixedly connected to the film applicator frame. The opening and closing rodless cylinder controls the movement of the slide table, thereby adjusting the spacing of the film applicator rollers.

[0010] Furthermore, the film pressing roller is connected to a fixing rod via a spring, and the two ends of the fixing rod are respectively fixedly connected to the film applicator frame and the support plate.

[0011] The advantages and positive effects of this utility model are: 1. Compared with traditional film lamination equipment, this structure can be used for double-row and multi-row extruded profiles of various widths and spacings.

[0012] 2. This equipment has added bottom rollers and side rollers at the feeding position, which can correct minor bends in the profiles and facilitate feeding.

[0013] 3. A two-sided opening and closing cylinder device has been added to the film application position to facilitate the opening and closing of the film application roller and the film pressing roller, making it easier for operators to adjust, feed materials and film.

[0014] 4. The four sets of pressure rollers on the rear side each have two independent sets of springs, ensuring that the pressure rollers adhere tightly to the surface of their respective opposite profiles during the pressure-pressing process. Compared to traditional methods, this design can adapt to profiles of different shapes, surface curvatures, and flatnesses. The overall structure is inexpensive and highly adjustable.

[0015] 5. The overall structure features a two-sided support structure for all supports, beams, and pressure rollers. Compared to the cantilever structure of traditional film applicators, the rollers are more stable and will not cause uneven pressure inside and outside the rollers.

[0016] 6. Unlike traditional film application structures, this equipment is an independent unit that can be freely placed in front of or behind the traction machine. The main frame can also be connected to the traction machine, packing machine, or strapping machine. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of this application clearer and easier to understand, the application will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only for explaining this application and are not intended to limit this application.

[0023] A dual-cavity, opposite-side laminating machine with automatic adjustment, see [link / reference]. Figure 1 As shown, the upper end of the chassis 3 is provided with a feeding limit mechanism 2 and a film application mechanism 1. The feeding limit mechanism 2 and the film application mechanism 1 are arranged at intervals along the feeding direction. The profiles that need to be filmed pass through the feeding limit mechanism 2 and the film application mechanism 1 in sequence. The feeding limit mechanism 2 corrects the slight bending of the profiles. The film application mechanism 1 applies film to the surface of the profiles.

[0024] The chassis 3 has a cubic box structure. The upper part of the chassis 3 is equipped with a horizontal worktable, and the four corners of the lower part of the chassis 3 are equipped with height-adjustable feet so that the chassis 3 can be stably supported on the ground.

[0025] See appendix Figure 2 As shown, the feeding limiting mechanism 2 includes a bottom feeding roller 204, two side rollers, an upper roller 212 and a lower roller 210. The bottom feeding roller 204 is connected to the worktable at the upper end of the machine box 3. The bottom feeding roller is used to support the profile from the bottom and reduce the resistance of the profile passing through. A lower support roller 210 is connected to the upper limit of the housing 3 behind the bottom support roller 204. The lower support roller 210 and the bottom support roller 204 are arranged parallel and spaced apart, and have the same height. The lower support roller 210 and the bottom support roller 204 support the profile, ensuring the profile is horizontal and reducing the resistance to passage. An upper support roller 212 is provided above the lower support roller 210. The height of the upper support roller 212 can be adjusted according to the thickness of the profile. The upper support roller 212 limits the height of the profile and works with the lower support roller 210 to maintain the levelness of the profile. The specific structure is as follows: a sleeve seat 211 is fixedly connected to both ends of the roller shaft of the lower support roller 210. The sleeve seat 211 is fixedly connected to the housing 3. A vertical through hole is provided in each sleeve seat 211. A downward pressing column 209 is fixedly connected to both ends of the roller shaft of the upper support roller 212. The downward pressing column 209 passes through the corresponding sleeve seat 211 and can move up and down. The lower end of the downward pressing column 209 is connected to the piston rod of the downward pressing cylinder 207. The cylinder body of the downward pressing cylinder 207 is fixedly connected to the housing 3. The extension and retraction of the piston rod of the downward pressing cylinder 207 can drive the downward pressing column 209 to move up and down, thereby controlling the lifting and lowering of the upper support roller 212.

[0026] In order to limit the lateral position of the profile, two feed side rollers 201 are provided at intervals on the housing 3 between the lower roller 210 and the bottom feed roller 204. The roller shafts of the feed side rollers 201 are vertically arranged, and the feed side rollers 201 on both sides are used to pass the profile. The two sides of the profile are limited by the feed side rollers 201. The spacing of the feed-side rollers 201 is adjustable. The feed-side rollers 201 are mounted on the feed-side roller support plate 205. The upper end of the feed-side roller support plate 205 is fixedly connected to a track 203 extending in the left-right direction. Two sliders 202 are slidably connected to the upper sides of the track 203, and a feed-side roller 201 is connected to each slider 202. A spacing adjustment screw 208 is engaged with the side of the slider 202. The other end of the spacing adjustment screw 208 is limited and connected to the feed-side roller support plate 205. Rotating the handle of the spacing adjustment screw 208 can drive the slider 202 to move back and forth along the track 203, thereby controlling the movement of the feed-side rollers 201.

[0027] The bottom feed roller 204 primarily facilitates material feeding. The spacing between the two side rollers can be adjusted by rotating the handle and screw at the bottom to accommodate the profile spacing and correct feeding tilt. The upper and lower pressure rollers are opened and closed by the bottom cylinder. After feeding, the upper roller presses down, maintaining partial pressure to compress the profile and correct feeding tilt.

[0028] See appendix Figure 3As shown, the film application mechanism 1 includes a film application frame 101, a material rack 102, a film pressing roller 103, and a film application roller 105. Both the film application frame 101 and the support plate 104 are flat structures. The film application frame 101 and the support plate 104 are fixedly fixed to the housing 3 at relative intervals. Multiple support rods 106 are fixedly connected between the film application frame 101 and the support plate 104. The material rack 102, the film pressing roller 103, and the film application roller 105 are connected between the film application frame 101 and the support plate 104. The film application frame 101 and the support plate 104 provide stable support force from the film pressing roller 103 and the film application roller 105 at both ends.

[0029] The upper and lower material racks 102 are arranged at intervals on the upper and lower sides of the film applicator frame 101. The film applicator rollers 105 are arranged opposite each other in the middle of the film applicator frame 101. The film applicator rollers 105 are provided with film covering material by the material racks 102 on the corresponding side. The film applicator rollers 105 are connected by an opening and closing component 107. The opening and closing component 107 can adjust the distance between the upper and lower film applicator rollers 105 and can open and close according to the size of the profile.

[0030] To ensure the tightness of the film application, a pressure roller 103 is provided on the sides of the film application roller 105 on both the upper and lower sides. An opening and closing component 107 is connected between the pressure rollers 103. The pressure rollers 103 on both the upper and lower sides can abut against the upper and lower end faces of the profile to press the film tightly.

[0031] The film-applying roller 105 and the film-pressing roller 103 are each connected to the opening and closing assembly 107 separately, and the spacing can be controlled independently.

[0032] See appendix Figure 4 As shown, the opening and closing assembly 107 includes a first positioning plate 1071, a second positioning plate 1073, a slide table 1072, and an opening and closing rodless cylinder 1074. The first positioning plate 1071 and the second positioning plate 1073 are arranged vertically at intervals. The outer side of the first positioning plate 1071 is fixed to the film applicator frame 101. Two slide tables 1072 that can slide vertically are installed at intervals on the inner side of the first positioning plate 1071. The two slide tables 1072 are used to connect the ends of the film applicator roller 105 and the pressure roller 103, respectively. One end of the opening and closing rodless cylinder 1074 is connected to each slide table 1072. The other end of the opening and closing rodless cylinder 1074 is connected to the second positioning plate 1073. The second positioning plate 1073 is fixedly connected to the film applicator frame 101. The opening and closing rodless cylinder 1074 controls the movement of the slide table 1072, thereby adjusting the spacing of the film applicator roller 105.

[0033] The opening and closing component 107 on one side of the support plate 104 is symmetrically arranged with the film applicator frame 101 and has the same structure.

[0034] To maintain the clamping force of the film pressing roller 103, the film pressing roller 103 is connected to the fixing rod 1033 via the spring 1032. The two ends of the fixing rod 1033 are respectively fixedly connected to the film applicator frame 101 and the support plate 104. The spring 1032 maintains pressure so that the film pressing roller 103 flexibly extrudes the surface of the profile.

[0035] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
