Description

Technical Field

[0001] This utility model relates to the technical field of film coating equipment, specifically to a film edge pressing component for a coating machine. Background Technology

[0002] A wrapping machine is a widely used piece of equipment in woodworking, architectural decoration, and furniture manufacturing. It is primarily used to adhere decorative films, wood veneers, or other covering materials to the surface of a substrate to improve the product's appearance and durability. A wrapping machine typically consists of a conveying mechanism, an adhesive applicator, a heating device, and a pressure roller mechanism. The pressure roller mechanism is responsible for applying uniform pressure to the covering material, ensuring a tight bond between it and the substrate surface and guaranteeing wrapping quality.

[0003] In the prior art, the pressure rollers of the coating machine are usually installed and fixed by a combination of multiple rods. Although this structural design can provide a certain degree of adjustability, the existing profiles are mostly concave and convex on the side. Therefore, when extending from the main surface to the side, the film needs to be edged. In the edged treatment of the film, multiple pressure rollers at different angles need to be arranged in an orderly manner at different positions to imitate the manual edged treatment. As a result, there are often more than 30 pressure rollers that are adjusted by multi-rod installation on both sides of the conveying mechanism.

[0004] When changing to substrates of different specifications or shapes, the angle and position of each pressure roller need to be adjusted individually. This adjustment process usually involves disassembling, re-fixing, or fine-tuning multiple linked components, which is complex and time-consuming, greatly reducing production efficiency. In addition, since the precision of the pressure roller adjustment depends on manual operation, it can easily lead to deviations in the coating effect between different batches of products, affecting the final product quality.

[0005] Therefore, how to provide a coating machine that allows for more convenient adjustment of the pressure rollers, adapts to the coating needs of different profiles, and improves production efficiency has become an urgent problem to be solved in this field. Utility Model Content

Detailed Implementation

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0034] The present invention will be further described below with reference to the embodiments.

[0035] Example:

[0036] This utility model provides a film edge-pressing assembly for a coating machine. The core improvement of this solution is to modify the existing pressure roller installation method, especially the installation method of the pressure rollers used for film edge-pressing. This allows for quick and efficient adjustment of the edge-pressing roller assembly for the concave and convex surfaces 71 when changing substrates 70 of different specifications or shapes, particularly aluminum profiles with concave and convex surfaces 71 of varying widths. Since adjusting the edge-pressing roller assembly is more difficult than adjusting conventional surface pressure rollers, the pressure roller assembly 1 in this solution is installed on both sides of the substrate 70 conveying mechanism, along the feeding direction of the substrate 70, and positioned behind the surface pressure rollers. It is mainly used for edge-pressing the film on the concave and convex surfaces 71 on both sides of the substrate 70.

[0037] Reference Figure 1-7In this scheme, the pressure roller assembly 1 includes a support rod 10 that serves as a mounting support. The end of the support rod 10 is rotatably connected to a horizontally arranged first pressure roller 11. During installation, the horizontal support rod 10 is fixed to the base rod 80 by a locking seat, and the entire pressure roller assembly 1 is fixed on both sides of the coating machine 2 by the base rod 80. The first pressure roller 11, which is horizontally arranged at the end of the support rod 10, is used to apply pressure and coat the film on the side of the substrate 70.

[0038] The moving part 20 is slidably mounted on the support rod 10. The moving part 20 can translate along the axial direction of the support rod 10, and a locking device 21 is provided between the two to restrict movement. In this embodiment, the main body of the support rod 10 is a stainless steel cylindrical rod. A groove 12 is milled into the surface of the support rod 10 along the axial direction. The moving part 20 is a keyway sleeve 22, which is keyed to the support rod 10 in the groove 12 section. Preferably, the locking device 21 is a tightening bolt, which is threaded onto the moving part 20, and its end contacts the outer surface of the support rod 10 to restrict movement between the two.

[0039] It also includes a second pressure roller 50 and a third pressure roller 60 for guiding the membrane body to complete a 90° bend at the concave-convex surface 71, and a connecting frame 40 for supporting and mounting the second pressure roller 50 and the third pressure roller 60; and an adjusting member 30 for quickly adjusting the upper and lower distance between the second pressure roller 50 and the third pressure roller 60. The two adjusting members 30 are symmetrically fixed on both sides of the moving member 20. The adjusting member 30 is mainly composed of a vertically arranged lead screw pair. Rotating the screw 32 of the lead screw pair can drive its moving pair 33 to move up and down. Translation; During installation, the near ends of the two connecting brackets 40 are fixed to the sliding pairs 33 on both sides, and the far ends are respectively rotatably equipped with a second pressure roller 50 and a third pressure roller 60. The second pressure roller 50, the first pressure roller 11, and the third pressure roller 60 are arranged sequentially along the feeding direction of the substrate 70, and the rotation axis of the second pressure roller 50 forms an angle of 40° to 50° with the rotation axis of the first pressure roller 11, and the rotation axis of the third pressure roller 60 forms an angle of -40° to -50° with the rotation axis of the first pressure roller 11. This solution is preferably designed for substrates 70 with many right-angled edges; therefore, in this embodiment, preferably, the rotation axis of the second pressure roller 50 forms an angle of 45° with the rotation axis of the first pressure roller 11, and the rotation axis of the third pressure roller 60 forms an angle of -45° with the rotation axis of the first pressure roller 11.

[0040] In summary, when it is necessary to replace the substrate 70 for wrapping in actual operation, the adjustment method of the pressure roller assembly 1 for edge wrapping in this solution is as follows: using the roller surface of the first pressure roller 11 in contact with the side of the substrate 70 as a reference, the locking device 21 is loosened so that the moving part 20 can drive the adjusting part 30 and other connecting parts, which facilitates the subsequent observation and adjustment of the second pressure roller 50 and the third pressure roller 60; according to the width of the concave and convex surface 71, the position of the second pressure roller 50 and the third pressure roller 60 is adjusted by manually rotating the screw of the adjusting part 30 so that their roller surfaces are respectively in contact with the right-angle corner edge of the concave and convex surface 71 at 45°, and finally the locking device 21 is tightened.

[0041] This solution uses symmetrically tilted second and third pressure rollers 50 and 60 in conjunction with the first pressure roller 11 to complete the edge wrapping of the membrane. The moving part 20 and its adjusting part 30 allow for rapid and precise adjustment of the positions of the second and third pressure rollers 50 and 60 to accommodate the edge wrapping needs of different profiles with varying widths of concave and convex surfaces 71. Compared to existing technologies where each pressure roller requires a multi-rod combination for adjustment, this solution greatly simplifies the adjustment operation and improves the overall adjustment efficiency of the pressure rollers. Furthermore, the close adjustment effect of the lead screw pair ensures good fit of the adjusted pressure rollers, guaranteeing smooth guidance of the membrane to complete a 90° bend without causing damage or wrinkling due to excessive stretching or compression. The rotation axes of the second and third pressure rollers 50 and 60 should be tilted at 45° relative to the conveying direction to ensure that the membrane can be smoothly bent along the edge of the profile while providing wrapping pressure. Of course, other specially shaped pressure rollers will be used to press the membrane after it has been bent by the third pressure roller 60; these are not shown in the figure and will not be described further here.

[0042] The following describes a preferred embodiment of this solution:

[0043] Adjusting component 30 also includes right-angle component 31. In this embodiment, right-angle component 31 is made of L-shaped angle steel, including a horizontal plate and a vertical plate that are vertically fixed at one end for supporting the screw pair. A square flange 23 is fixed on the outside of the keyway sleeve 22. The vertical plate and the square flange 23 have countersunk screw holes, which are fixed to the square flange 23 with countersunk screws.

[0044] In addition, a nut part 311 is provided on the horizontal plate, and the main body of the screw 32 is screwed to the nut part 311. A pair of guide grooves 312 are provided on the vertical plate. One end of the screw 32 is rotatably connected to the sliding pair 33. When the screw 32 is rotated, the sliding pair 33 moves up and down along the guide groove 312. The sliding pair 33 is provided with threaded holes at the corresponding positions of the guide grooves 312. A plug screw is used to pass through the guide grooves 312 and connect to the threaded holes of the sliding pair 33. The guide of the sliding pair 33 is achieved by the cooperation of the smooth part of the plug screw with the guide groove 312.

[0045] In this embodiment, in order to fix the second pressure roller 50 or the third pressure roller 60 at ±45° at the end of the connecting frame 40, the connecting frame 40 is designed to include two parts: a square tube 41 and a support rod 42. The square tube 41 is a 15×15×1.5 square tube, and the support rod 42 is a stainless steel round rod. The sliding pair 33 is provided with a square hole 34 that matches the cross-section of the square tube 41. The square hole 34 is at a 45° angle to the horizontal plane, and the support rod 42 is fixed at 45° on the square tube 41.

[0046] Specifically, the support rod 42 has a flat surface 421 machined at one end, which is fixed to the square tube 41. The support rod 42 is then fitted and fixed to the square tube 41 via the flat surface 421. Simultaneously, an elongated hole 411 is provided on the square tube 41 to facilitate the fixing of the support rod 42 with screws passing through the hole. A guide protrusion 422 is provided on the flat surface 421 of the support rod 42. The guide protrusion 422 fits into the elongated hole 411, providing good positioning and making assembly and fixing easier. A second pressure roller 50 or a third pressure roller 60 is fixed to the other end of the support rod 42. The second pressure roller 50 is coaxially fixed to the support rod 42, while the third pressure roller 60 is perpendicularly fixed to the support rod 42. Both the second pressure roller 50 and the third pressure roller 60 are fixed by having mounting holes at the ends of the rods and being locked in place with set screws.

[0047] 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.
