Description

A folding machine

technical field

The utility model relates to a paper folding device for an edge wrapping machine.

Background technique

At present, after the gypsum board is trimmed and shaped, it needs to be edge-sealed, that is, the two sides of the sawn edge of the slab are sealed with adhesive tape to prevent the corners of the slab from being damaged due to bumps during transportation. The equipment that realizes this process is called hemming machine in sheet metal processing.

The edge-wrapping paper used in the edge-wrapping process is a tape with wet water on one side (only sticky when it meets water), and the tape width is 50mm. The V-groove gradient process on the nylon wheel gradually moves the tape closer to the sides of the board, folds the tape paper into a "side U" shape, and finally wraps the tape paper to both sides of the board edge by pressing the roller. This kind of process equipment structure that relies on V-shaped grooves to change paper delivery is relatively complicated. The three nylon wheels need to be tightened on the edge of the plate by pressing the cylinder. When producing plates with different thicknesses, it is necessary to replace nylon wheels of different sizes. Hemming of different board thicknesses.

Utility model content

The technical problem to be solved by the utility model is to provide an edge-folding machine folder with simple structure, low cost and high working efficiency when replacing plates with different thicknesses.

In order to solve the above-mentioned problems, the utility model provides a paper folding device for an edge-binding machine, which includes: a groove whose cross-section gradually changes along the extension direction, and the groove includes a bottom surface and side wings extending in the same direction on both sides of the bottom surface. The bottom surface is trapezoidal, and the angle between the side wings and the bottom surface gradually decreases along the direction in which the width of the trapezoid decreases.

Further, the symmetrical connection of the wings is arranged on both sides of the bottom surface.

Further, the angle between the side wing and the bottom surface gradually decreases from an obtuse angle to a right angle.

Further, the bottom surface and the side wings are connected with rounded corners.

Further, a spring and a rotating shaft are connected to each other on the side of the bottom surface extending away from the side wings.

The utility model has the following advantages:

1. The utility model adopts a trapezoidal bottom surface and flanks with gradually smaller angles with the bottom surface, which can facilitate tape paper to gradually change from a strip shape to a small-side V-shape, and then to a large-side V-shape when passing through the gradient groove. Finally change to U-shaped, the process is simple and reliable, and the cost is low, and then only need to use a v-shaped wheel, and only need to replace the wheel when it needs to be replaced, which greatly improves the work efficiency.

2. The utility model has simple structure, convenient and reliable operation and use, and the utility model has low production cost and is convenient for popularization and use.

Description of drawings

Below in conjunction with accompanying drawing, the embodiment of the present utility model is further described:

Fig. 1 shows a structural schematic diagram of a paper folding device of a hemming machine of the present invention;

Fig. 2 shows a schematic diagram of cross-section changes of a folding device of an edge-binding machine according to the present invention.

Detailed ways

As shown in Fig. 1 and Fig. 2, the utility model comprises a groove 1 whose cross-section gradually changes along the extension direction. The angle α between the trapezoid and the bottom surface 2 gradually decreases along the direction in which the width of the trapezoid decreases.

The utility model adopts the trapezoidal bottom surface 2 and the flanks 3 whose angles with the bottom surface 2 become gradually smaller, so that when the adhesive tape passes through the gradient groove 1, it gradually changes from a belt shape to a small side V shape, and then changes to a large side V shape. type, and finally changed to u-type, the process is simple, reliable, and low in cost, and then only one v-shaped wheel is needed, and only the wheel needs to be replaced when it needs to be replaced, which greatly improves the work efficiency.

In the present utility model, the side wings 3 are symmetrically connected and arranged on both sides of the bottom surface 2 .

In the present utility model, the angle α between the wing 3 and the bottom surface 2 gradually decreases from an obtuse angle to a right angle.

In the present utility model, the fillet transition connection between the bottom surface 2 and the side wings 3 . Use rounded transitions to avoid tape damage during the gradient process.

In the present utility model, a spring 4 and a rotating shaft 5 are connected to one side of the bottom surface 2 extending away from the side wings 3 . The use of the spring 4 and the rotating shaft 5 can conveniently guide the adhesive tape against the plate.

The utility model has simple structure, convenient and reliable operation and use, and the utility model has low production cost and is convenient to popularize and use.

In summary, the above are only preferred embodiments of the present utility model, and are not used to limit the scope of protection of the present utility model. Therefore, any modifications, equivalent replacements, Improvements and the like should all be included within the protection scope of the present utility model.
