Technical Field

[0001] This utility model provides a width limiting component for a laminating machine, belonging to the technical field of laminating machines. Background Technology

[0002] A laminating machine is a widely used piece of equipment in industries such as printing, packaging, and advertising. Its main function is to coat plastic film with adhesive and then laminate it with substrates such as paper and fabric under pressure to form a paper-plastic composite product, achieving the purpose of protection and increasing gloss. During the lamination process, the alignment accuracy of the laminating materials is crucial, and existing laminating machines are usually equipped with width limiting devices for this purpose.

[0003] However, existing limiting devices generally suffer from the following drawbacks: inconvenient adjustment and low precision. Many limiting devices require manual loosening of screws, movement of the baffle, and then tightening again for adjustment. This method is cumbersome, time-consuming, and not conducive to achieving precise positioning of the baffles on both sides. This is especially problematic when frequently changing laminating materials of different widths, severely impacting production efficiency. Therefore, this invention provides a width limiting component for a laminating machine. Utility Model Content

[0004] The technical problem solved by this utility model is that the operation method of adjusting the baffle by tightening and loosening screws is cumbersome and time-consuming, which is not conducive to achieving accurate positioning of the baffles on both sides and seriously affects production efficiency.

[0005] To solve the technical problem, the technical solution provided by this utility model is: a width limiting component for a laminating machine, including a pair of support plates, and further comprising:

[0006] A width limiting component for limiting the edge of the coating material includes a rectangular seat fixedly disposed between the tops of the support plates. The rectangular seat has symmetrical through grooves on both sides of its top. A slider is slidably connected in the through groove. A screw threadedly connected to the slider is rotatably connected between the inner sidewalls of the through groove. A vertical rod is provided at the bottom of the slider. A mounting plate is provided at the bottom of the vertical rod. Several limiting rollers are rotatably connected at equal intervals at the bottom of the mounting plate.

[0007] Furthermore, the lower part of the side wall of the support plate is provided with mounting holes, and a pair of support plates are respectively fixedly installed on both sides of the conveyor belt of the laminating machine. The gap between the bottom of the limiting roller and the top of the conveyor belt of the laminating machine is 2-4mm.

[0008] Furthermore, one end of the screw extends through the through groove and is equipped with a handwheel, and the two inner sidewalls of the through groove are symmetrically provided with limiting rails that match the sidewalls of the slider.

[0009] Furthermore, the rectangular seat has a scale line on one side of the through groove on its side wall.

[0010] Furthermore, the mounting plate is provided with symmetrical reinforcing plates on both sides of its top, which are fixedly connected to the pole body.

[0011] Furthermore, the limiting roller is made of polyurethane or silicone.

[0012] The beneficial effects of this utility model are:

[0013] With precise adjustment and convenient operation, the width limiting component, along with the handwheel, screw, slider, and limiting rollers, allows operators to easily drive the limiting rollers on both sides by simply turning the handwheel. This constrains the film's position within the set width range, ensuring that the laminating material enters the subsequent lamination and pressing process straight and smoothly, effectively preventing offset and wrinkling issues. The adjustment process is simple, labor-saving, stable, and fast. Combined with the scale lines, it facilitates rapid and accurate positioning of films of different widths, greatly improving production preparation efficiency. Attached Figure Description

[0019] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly mentioned in this specification are defined relative to their structure and are relative concepts. Therefore, they may vary depending on their location and usage; thus, these or other directional terms should not be interpreted as restrictive terms.

[0020] The singular forms “a,” “the,” and “the” used in this specification are intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes one or more of the associated listed items, any or all possible combinations thereof.

[0021] To make the technical problems to be solved, the technical solutions, and the beneficial effects of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0022] According to the appendix Figure 1 , 2 As shown in Figure 4: This utility model provides a width limiting component for a laminating machine: it includes a pair of support plates 1, with mounting holes 10 on the lower part of the side wall of the support plates 1. The pair of support plates 1 are respectively fixed on both sides of the conveyor belt of the laminating machine by bolts. It also includes a width limiting component 2 for limiting the edge of the laminating material, including a rectangular seat 3 fixedly disposed between the tops of the support plates 1. The top two sides of the rectangular seat 3 are symmetrically provided with through grooves 4. A slider 5 is slidably connected in the through groove 4. A screw 6 is rotatably connected between the inner side walls of the through groove 4 and threadedly connected to the slider 5. One end of the screw 6 passes through the through groove 4 and is provided with a hand. The bottom of the slider 5 is equipped with a vertical rod 7, and the bottom of the vertical rod 7 is equipped with a mounting plate 8. Several limiting rollers 9 are equidistantly rotatably connected to the bottom of the mounting plate 8. The gap between the bottom of the limiting rollers 9 and the top of the conveyor belt of the laminating machine is 2-4mm. This gap ensures that the laminating material can pass smoothly, while the limiting rollers 9 can effectively restrain its edges and prevent it from warping or shifting. Specifically, by holding the handwheel and rotating it, the screw 6 is rotated, which in turn moves the slider 5, which in turn moves the vertical rod 7 and the mounting plate 8, which in turn moves the several limiting rollers 9 at the bottom of the mounting plate 8.

[0023] As an optional embodiment, those skilled in the art can obtain the following based on their own knowledge and common sense: for the problem of dust and rust on the exposed screw, the dust can be cleaned regularly; for the screw, galvanizing or coating can be used to prevent rust and increase service life; when it is rusted to the point of being unusable, it can be replaced.

[0024] As per the instruction manual Figure 2 , 3As shown: The two inner sidewalls of the through groove 4 are symmetrically provided with limiting rails 11 that match the sidewalls of the slider 5, which serve to limit the slider 5. The sidewall of the rectangular seat 3 is provided with scale lines 12 placed on one side of the through groove 4, which facilitates observation of the adjustment position of the limiting roller 9. The top two sides of the mounting plate 8 are symmetrically provided with reinforcing plates 13 that are fixedly connected to the body of the upright 7, which serve to strengthen the fixation. The limiting roller 9 is made of polyurethane or silicone, which has good wear resistance, elasticity and low coefficient of friction, and a smooth surface. As a part that comes into direct contact with the film, it can effectively prevent scratching or damaging the edge of the film during the limiting process, thus protecting the integrity of the coating material.

[0025] The principle of this utility model

[0026] Installation: First, install this component symmetrically on both sides of the laminating machine conveyor belt through the mounting holes 10 and bolts on the support plate 1. During installation, ensure that the gap between the limit roller 9 and the conveyor belt meets the requirement of 2-4mm.

[0027] Adjustment: Before the lamination operation, according to the width of the material to be laminated, the operator can move several limiting rollers 9 at the bottom of the mounting plate 8 by holding the handwheel and rotating it. The operator can observe the position of the edge of the slider 5 on the scale line 12 and precisely adjust the inner distance between the two sets of limiting rollers 9 to a size slightly larger than the width of the film, for example, 0.5-1mm larger than the width of the film.

[0028] Limiting: When the laminating machine starts and the laminating material is conveyed forward on the conveyor belt, its two side edges will enter the channel formed by two sets of limiting rollers 9. Once the film tends to shift to one side during the conveying process, its edge will immediately contact the limiting roller 9 on that side. Since the limiting roller 9 is rotatable, it will roll in the direction of the film's movement with minimal friction, while applying a reverse lateral support force to push the film back to the correct track. The setting of multiple rollers makes the contact smoother and the support force more uniform. The whole process dynamically constrains the position of the film within the set width range, thereby ensuring that it enters the subsequent laminating and pressing process straight and smoothly, effectively avoiding problems such as shifting and wrinkling.

[0029] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
