Description

Technical Field

[0001] The utility model relates to the technical field of thermochromic sticker processing, in particular to a multi-layer material bonding device for thermochromic sticker processing. Background Art

[0002] Thermochromic stickers are stickers that can change color according to a specific temperature. This type of sticker is made using the color-changing principle of thermochromic pigments. The color-changing principle of thermochromic stickers is the same as that of thermochromic powders. The color change is controlled by using the temperature difference. The basic structure of thermochromic stickers includes a transparent plastic film layer, a temperature-sensitive material layer, a substrate layer and an adhesive layer. During the production and processing of thermochromic stickers, bonding equipment is required to bond different materials to the substrate layer. After winding, the thermochromic stickers are obtained through cutting equipment.

[0003] In the prior art, when gluing the substrate layer, the substrate is continuously conveyed through the transmission roller, and one side of the substrate is glued by the gluing roller. However, during the unwinding process of the substrate through the unwinding roller and the transmission process of the changing transmission roller, the side of the substrate may be folded. Once the substrate is folded, it is difficult to automatically recover. The subsequent substrate continues to be conveyed in the folded state, and the equipment needs to be stopped immediately, which affects the production efficiency and causes economic losses to the enterprise.

[0004] To this end, we designed a multi-layer material bonding equipment for the processing of thermochromic stickers. Utility Model Content

[0005] In order to automatically correct the deviation of the substrate being transmitted before gluing, if the substrate is folded, it is difficult to automatically recover. The subsequent substrate continues to be transmitted in the folded state, and the equipment needs to be stopped immediately, which affects the production efficiency and causes economic losses to the enterprise. The utility model provides a multi-layer material bonding equipment for processing thermochromic stickers.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] The unwinding roller is driven by the output end of the first motor to unwind the substrate. Since the unwinding roller and the winding roller are driven by a pair of pulleys and a transmission belt, the substrate is transported on the conveying mechanism, wherein a plurality of direction-changing transmission rollers are located at the same height, so that the transported substrate is in a horizontal state between the direction-changing transmission rollers, which is convenient for the subsequent glue brushing mechanism on the support table to bond the substrate and the glue.

[0009] A support platform is provided on the processing table, the glue brushing mechanism is arranged on the support platform, a plurality of pairs of correcting mechanisms are provided on the processing table, the correcting mechanisms include a plurality of correcting plates for automatically correcting folded substrates, and a driving mechanism for driving the plurality of pairs of correcting mechanisms is provided on the processing table.

[0010] Optionally, the support platform is disposed between a plurality of direction-changing transmission rollers, and the lower surface of the substrate transmitted between the plurality of direction-changing transmission rollers contacts the surface of the support platform.

[0011] By adopting the above technical solution, the support table is used to facilitate the glue brushing mechanism to brush glue on the transmitted substrate, so that the glue is bonded to the substrate.

[0012] Optionally, the glue brushing mechanism includes a glue box and a glue roller, the glue box is set on the support table through a mounting plate, a gap is left between the bottom surface of the glue box and the table surface of the support table, both ends of the glue roller are rotatably connected to the glue box, the upper end of the glue roller is placed in the cavity of the glue box, and the lower end contacts the upper surface of the substrate on the support table, the glue box stores glue, and multiple pairs of scrapers are symmetrically arranged on both sides of the glue roller.

At the same time, a plurality of scrapers are provided on the glue box, and the plurality of scrapers are symmetrically arranged on both sides of the glue roller, so as to effectively control the amount of glue attached to the glue roller, which is beneficial to ensure uniform adhesion of the glue on the substrate.

[0014] Optionally, the deviation rectifying mechanism further includes a fixed cylinder, a mounting bracket and a rotating rod. The fixed cylinder is fixedly arranged on the processing table. The top end of the fixed cylinder is fixedly connected to the mounting bracket. The rotating rod is coaxially inserted into the fixed cylinder. One end of the rotating rod close to the processing table is coaxially and fixedly connected with a second bevel gear, and the other end penetrates through the mounting bracket. The end of the rotating rod penetrating through the mounting bracket is fixedly connected to a connecting piece. The cross section of the rotating piece is a workpiece with an obtuse included angle.

Through the meshing drive between the first bevel gear and the second bevel gear, the rotating rod coaxially fixedly connected to the second bevel gear rotates. The rotating rod drives the rotating piece to rotate. The rotating piece is rotatably connected to the connecting piece. At the same time, the connecting piece and the cross shaft form a universal joint structure. One end of the connecting piece close to the rotating piece rotates around the center point of the cross shaft under the rotation of the rotating piece. Since the cross shaft is respectively rotatably connected to the mounting bracket and the connecting piece, and the deviation rectifying plate is fixedly connected to the cross shaft, that is, the cross shaft only has the freedom of swinging. Since a pair of first bevel gears are located between a pair of second bevel gears, the rotating rod rotates in opposite directions at the same time. The two sides of the base material are slapped and rectified by a pair of deviation rectifying plates. Through the tensioning adjustment of the tensioning pulley, it is ensured that the base material remains in a taut state during the conveying process.

When the substrate is not folded, a pair of correction plates are placed vertically on both sides of the substrate to play a role of limiting guidance. Once the high-precision camera detects that the substrate is folded during the transmission process, the high-precision camera transmits the monitored image information to the control board through an electrical signal, and the control board controls the output end of the second motor to work, which reacts sensitively and avoids the subsequent substrate from continuing to be transmitted in a folded state. There is no need to stop the equipment immediately to ensure the production efficiency of the color-changing stickers.

[0021] The beneficial effects of the utility model are:

[0022] 1. The utility model realizes multiple pairs of correction mechanisms to beat and correct the two sides of the substrate through the cooperation of the second motor, the fourth bevel gear, the third bevel gear, the rotating shaft, the first bevel gear, and the second bevel gear.
