Abstract

A method and device for automatically pasting the edges of filter elements, which can automatically pasted the edges of folded paper, and is characterized by: cutting and rolling up the materials for pasting; setting a paper feeding, gluing, and pasting device, placing the rolled paper rolls on both sides of the device, and feeding the paper through the vertical paper feeding mechanisms on both sides, and then gluing it with hot melt glue, while the folding paper feeding mechanism in the middle simultaneously feeds the folded paper, and then the pasting mechanisms on both sides press the glued paper to the middle for pasting. Finally, the filter element with pasted edges only needs to be cut according to the specifications. It can save a lot of personnel, and the speed is fast, which effectively improves productivity.

Description

Method and device for automatic welting of filter elements

Technical field

The invention relates to a method and a device for producing an air cleaner filter element, in particular to a method and a device for automatic welting of the filter element.

Background technique

At present, when producing the filter element of the air filter, some varieties need to paste the folded paper. These welts are all done by hand: first cut the material used for the welt into pieces of appropriate length and width, and then one person passes the paper pieces through the glue coating machine one by one, and the other person puts the glued paper into pieces. Glue the paper to the edge of the folded paper. The speed is slow, and because the hot melt adhesive is hot, it often burns the workers' hands. Inefficient and not safe enough.

Contents of the invention

In order to overcome the deficiencies of the existing welting methods, the purpose of the present invention is to provide a method and device for automatic welting of filter elements, which can conveniently realize welting and improve productivity.

The technical scheme that the present invention adopts to solve its technical problem is: the material that welt is used is cut, glued, welt. Its characteristics are: cut, roll up and put the material for welting on the paper roll seat; set up a paper feeding, gluing and welting device, and there are mechanisms on both sides of this device that can feed paper vertically, and can press the paper The welting mechanism that welts toward the middle; and the folding paper mechanism in the middle; put the rolled paper roll on both sides of the device, so that the paper is sent by the vertical paper feeding mechanism on both sides, and then glued, and the middle one The origami feeding mechanism sends the folded paper synchronously, and then the welting mechanisms on both sides press the glued stickers to the middle welt. Finally, you only need to cut the filter element with the side attached according to the specification. It can save a lot of personnel, and the speed is fast, which effectively improves the productivity.

The beneficial effect of the invention is that the productivity is effectively improved and the cost is saved.

Description of drawings

The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

Fig. 1 is a front view of the first embodiment of the present invention.

Fig. 2 is a side view of the first embodiment of the present invention.

In the figure 1. Welting mechanism, 2. Vertical paper feeding mechanism, 3. Hot melt adhesive machine, 4. Paper folding mechanism, 5. Paper roll holder, 6. Paper folding machine.

In Fig. 1 and Fig. 2, the paper feeding, gluing, and welting devices consist of a welting mechanism (1), a vertical paper feeding mechanism (2), a hot melt adhesive machine (3), a folding paper feeding mechanism (4) and a paper roll seat (5) Composition. The paper roll seat (5) places the paper roll, and the vertical paper feeding mechanism (2) pulls the paper for welting from the paper roll and sends it out vertically, while the hot melt glue machine applies glue to it, and at the same time, the middle paper feeding mechanism ( 4) The folded paper is sent synchronously, and then the welting mechanism presses the sticker to the middle welt. Finally, it is only necessary to cut the filter element with the side attached according to the specification, and it can even be cut manually. In this way, the entire production line consisting of paper feeding, gluing, welting devices and paper folding machines only needs two people from origami to welting and cutting, saving many people and increasing the speed a lot. In this embodiment, the vertical paper feeding mechanism (2) is composed of two sets of vertical rollers that can be engaged, the paper feeding mechanism (2) is composed of a belt mechanism, and the welting mechanism (1) is composed of two groups of vertically mounted movable rollers. The arm consists of rollers.

The different method of replacing manual welting also lies in that the paper sheets used for welting do not need to be cut into small pieces but cut into paper rolls. At the same time, the paper feeding, gluing, and welting devices are also directly installed behind the origami machine.
