[0021] The technical solutions in the embodiments of the present utility model will be described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.
[0022] A feeding mechanism for linerless self-adhesive paper includes linerless self-adhesive paper, a conveying and peeling device, and a gluing device. The conveying and peeling device includes at least three fulcrums, two of which are roller fulcrums, and one of which is a peeling fulcrum. The three fulcrums are connected by a conveyor belt. The gluing device is arranged between the two roller fulcrums. The linerless self-adhesive paper is placed on the conveyor belt, conveyed and peeled by the conveying and peeling device, and made sticky by the gluing device. The gluing device is a heating device. The linerless self-adhesive paper includes a sticker layer and a hot melt adhesive layer, and the hot melt adhesive layer is arranged at the bottom of the sticker layer. The heating device includes a shell cover, a heating rod and a bracket. The base is arranged on both sides of the conveyor belt, the shell cover is fixedly mounted on the bracket, and the heating rod is arranged on the inner wall of the shell cover. Pressure rollers are arranged at the front and rear ends of the heating device, one end of the pressure roller is fixedly mounted on the shell cover, and the other end is against the conveyor belt. The conveyor belt is made of rubber. The pressure roller includes a base, a connecting rod and a roller. The base is fixedly mounted on the shell, and the roller is against the surface of the conveyor belt. The base and the roller are connected by a connecting rod. A reset spring is provided in the base, and the reset spring is connected to the connecting rod to keep the roller with pressure on the conveyor belt. A triangular support plate is provided at the stripping fulcrum, and the triangular support plate is arranged on the inner side of the conveyor belt so that the angle of the conveyor belt at the stripping fulcrum is less than 60°. A stripping hanging plate is also provided at the stripping fulcrum, and the bottom of the stripping hanging plate is on the surface of the conveyor belt.
[0023] This application is based on the improvement of traditional self-adhesive and labeling machines, so the frame or other basic structures will not be described in detail, and only the innovative points of this patent will be described.
[0024] The actual usage process is as follows:
[0025] The facial tissue paper is fed into the conveyor belt individually or in a roll. The bottom of the facial tissue paper is provided with hot melt adhesive, which is not activated at room temperature and has no stickiness. When the facial tissue paper enters the heating device, the temperature in the heating device is about 60 degrees Celsius to 100 degrees Celsius. At this time, the hot melt adhesive on the back of the facial tissue paper melts and becomes sticky, making it stick to the conveyor belt.
[0026] There are pressing rollers at both ends of the heating device. The paper is pressed flat for the first time before entering the heating device. After being heated and made sticky, it passes through the pressing roller at the rear end of the heating device and is pressed flat for the second time. This ensures that the paper is flat and fits the conveyor belt perfectly.
[0027] The facial paper is attached to the conveyor belt and then conveyed to the peeling fulcrum. The peeling fulcrum has a small angle, usually less than 30°. The small angle enables the facial paper to be naturally peeled off when conveyed to this position. If it cannot be peeled off naturally, a peeling scraper is provided at its lower end. The end of the peeling scraper is tightly attached to the peeling fulcrum, which can complete the peeling process between the facial paper and the conveyor belt.
[0028] The present application also has another alternative scheme, in which the heating device is replaced by a brushing device. A plurality of brushing holes can be set on the surface of the conveyor belt. The brushing device is set below the conveyor belt between the two roller fulcrums. When the facial paper passes by, its bottom is coated with glue by the brushing device to make it sticky. The subsequent steps are the same as those using the heating device.
[0029] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above-mentioned exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present invention is limited by the appended claims rather than the above description, and it is intended that all changes within the meaning and scope of the equivalent elements of the claims are included in the present invention.
