Description

Gluing machine with adjustable gluing width

technical field

The utility model relates to a gluing machine, in particular to a gluing machine capable of continuously gluing paper in progress.

Background technique

The gluing machine for continuous gluing of paper in progress includes a rotating roller and a long glue storage tank. The length direction of the glue storage tank is parallel to the axis of the rotating roller. The cylindrical surfaces of the rotating rollers are in contact. When the gluing machine is working, the glue in the glue storage tank overflows to the edge of the notch. With the rotation of the rotating roller, the cylindrical surface of the rotating roller contacting the edge of the notch is coated with glue, and the rotating roller coated with glue and The other turning rollers make contact, and the glue is rolled onto the paper by other turning rollers. The axial coverage of the glue on the cylindrical surface of the rotating roller, that is, the gluing width of the glue, is determined by the length of the notch edge of the glue storage tank, and the length of the notch edge of the glue storage tank is fixed. Therefore, in order to ensure that the paper can be coated with glue in the entire width, the length of the glue storage tank of the existing gluing machine is greater than the width of the paper. Yet like this will cause those glues that exceed paper width on the cylindrical surface of rotating roller to accumulate more and more, thereby make the position near the edge of paper be glued too much. Paper with too much glue will bring glue to other parts of the gluing machine, causing the paper to stick to other parts, causing paper wrapping failures. Paper wrapping faults forced the glue machine to stop, reducing production efficiency.

In order to avoid paper wrapping faults, the existing technology makes the rotating roller coated with glue in the gluing machine into a stepped shaft structure. The length of the middle section of the stepped shaft corresponds to the width of the paper, and the middle section is thicker, so that only The middle section is only coated with glue. Although this can solve the paper wrapping problem, it increases the processing difficulty of the turning roll, and has to prepare turning rolls of various specifications for various wide-width papers, which increases the production cost.

Utility model content

The purpose of the utility model is to provide a gluing machine with adjustable gluing width which can avoid paper wrapping failure.

The utility model is realized in this way: the gluing machine with adjustable gluing width includes a rotating roller and a rubber storage tank, the notch edge of the rubber storage tank is in contact with the cylindrical surface of the rotating roller, and the rubber storage tank is provided with a position-adjustable end plate, the edge of the end plate is in contact with the cylindrical surface of the rotating roller.

The actual effective length of the glue storage tank can be changed by adjusting the distance between the end plates of the glue storage tank, so that the axial coverage of the glue on the cylindrical surface of the rotating roller can be adjusted according to the width of the paper, that is, the glue can be adjusted The gluing width can avoid paper wrapping failure caused by too much gluing on the paper.

The utility model has the following advantages: 1. The corresponding gluing width can be adjusted according to different paper widths, and the adaptability is strong; 2. There is no need to make the rotating roller into a stepped shaft structure, and there is no need to adjust the width of the paper to adapt to different widths of paper. The rolling rolls of various specifications are prepared, thereby reducing the production cost.

Fig. 2 is a top view of Fig. 1, but the paper in Fig. 1 is omitted.

Detailed ways

Referring to Fig. 1 and Fig. 2, the gluing machine includes a rotating roller 1, and the axis of the rotating roller 1 is parallel to the horizontal plane. The cylindrical surface of the rotating roller 1 is in contact with the edge of a scraper 2 . The other edge of the scraper 2 is in close contact with a stationary roller 3 that does not rotate. The fixed roller 3 is provided with an axial groove 11, which forms a long rubber storage tank together with the scraper 2. The length direction of the rubber storage tank is parallel to the axis of the rotating roller 1. The notch of the rubber storage tank The edge is exactly the edge where the scraper 2 is in contact with the rotating roller 1, and the glue sprayed from the glue spray port 4 accumulates in the glue storage tank. The utility model is characterized in that the rubber storage tank is provided with an adjustable end plate 5, and the edge of the end plate 5 is in contact with the cylindrical surface of the rotating roller 1.

The end plate 5 is connected to the fixed roller 1 by screws 6 . A plurality of screw holes 7 arranged along the axial direction of the fixed roller are opened in the groove 11 of the fixed roller 1 , and the installation position of the end plate 5 can be changed by connecting the screws 6 to different screw holes 7 . The glue ejected from the glue nozzle 4 is accumulated between the two end plates 5 . By changing the distance between the end plates 5, the actual effective length of the glue storage tank can be changed, that is, the width of glue application can be changed. The flow of glue sprayed from the glue spray port 4 should match the amount of glue taken away by the rotating roller 1 from the edge of the notch of the glue storage tank, so as to ensure that the glue in the glue storage tank will not overflow from the end plate 5.

When the gluing machine is working, the three rotating rollers 1, 8, and 9 shown in the figure rotate synchronously. The outer peripheral linear speed of the three rotating rollers is equal to the traveling speed of the paper 10. The glue sprayed from the glue spray port 4 passes through the cylinder of the rotating roller 1. The surface flows into the glue storage tank, and the glue overflows to the edge of the notch of the glue storage tank. With the rotation of the rotating roller 1, the cylindrical surface of the rotating roller 1 is coated with glue, and the glue covers the axial direction of the cylindrical surface of the rotating roller 1. The range, that is, the glue width of the glue, is equal to the distance between the two end plates 5, and the rotating roller 1 rolls the glue coated on its cylindrical surface to another rotating roller 8 in contact with it, and the other rotating roller 8 A turning roller 8 rolls the glue onto the paper 10 .
