Description

Technical Field

[0001] The utility model relates to a water glue machine, more specifically to an automatic paper feeding adjustment device for the water glue machine. Background Art

[0002] In many industries involving paper processing, such as modern packaging and printing, water glue machines play an extremely important role. They can efficiently apply glue to paper and assist in the subsequent bonding process. With the continuous advancement of automation technology, water glue machines are equipped with automatic paper feeding functions, aiming to further improve production efficiency, reduce labor costs and ensure the continuity and accuracy of the paper feeding process. However, the actual operation process is not satisfactory, and a prominent problem gradually emerges - the position of manual paper feeding is inaccurate. This problem does not occur by chance. On the one hand, due to the huge differences in the proficiency of different operators, novice employees often find it difficult to accurately grasp the initial position of each paper feeding. Even experienced old employees are prone to deviations due to factors such as fatigue after long-term repetitive operations; on the other hand, from the perspective of the equipment itself, there are certain defects in the connection design between the automatic paper feeding system and the manual paper feeding link, and there is a lack of effective positioning and guidance mechanism, which makes it difficult for operators to ensure that the paper is in an ideal, system-preset starting state when placing the paper on the paper position, which in turn brings many obstacles to the subsequent automatic paper feeding process, which is not only easy to cause paper jams and reduce production efficiency, but also may cause uneven glue application and affect product quality.

[0014] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0015] Reference Figures 1 to 4As shown, an automatic paper feeding adjustment device for a water-gluing machine of the present embodiment is characterized in that it includes a laser sensor 1 and a paper feeding table 2, wherein the laser sensor 1 is fixedly mounted on an external frame and is located above the inner side of the paper feeding table 2 for detecting the edge of the paper, and the laser sensor 1 is communicatively connected with the paper feeding table 2 so that when the laser sensor 1 detects the inner edge of the paper on the paper feeding table 2, the paper feeding table 2 adjusts the left and right positions of the paper, and during the paper feeding process, the staff only needs to place the paper on the paper feeding table 2 and push the paper into place, and when the paper is pushed into place, the laser sensor 1 will detect the side edge of the paper, so that the paper feeding table 2 knows that the paper has been pushed into place, and then the left and right positions of the paper are adjusted through the adjustment function of the paper feeding table 2.

[0016] In this embodiment, a method of adjusting the left and right position of the paper is provided by moving the paperboard 22 left and right on the adjustment chassis 21. That is, when the paper is pushed into place, the paper is on the paperboard 22, and the translation of the paperboard 22 is used to further drive the translation of the paper to achieve left and right adjustment of the paper. For this purpose, the following structure is provided, in which a driving device 23 is used to communicate with the laser sensor 1 and is also used as a power source to drive the paperboard 22 to move left and right. The adjustment chassis 21 is used as the basic structure. At the same time, in the subsequent automatic paper feeding process, the paper is transported one by one by adjusting the chassis 21 to rise.

[0017] In this embodiment, a simple driving device 23 structure is provided, which is specifically composed of a driving motor 231, a driving gear 232 and a driving rack 233. The driving rack 233 is fixedly installed on the lower side of the paperboard 22, and the body of the driving motor 231 is fixedly installed on the adjustment base frame 21. The driving gear 232 is coaxially sleeved on the rotating shaft of the driving motor 231 and meshes with the driving rack 233 for transmission.

A transmission gear 213 is rotatably provided on the driving base plate 212. The transmission gear 213 is meshed between the driving gear 232 and the driving rack 233. The left and right translation speed can be adjusted by adjusting the size of the transmission gear 213 by utilizing the effect of the transmission gear 213.

[0019] In this embodiment, in order to allow the paperboard 22 to have better translation performance, a plurality of rolling bearings 214 are rotatably provided on the side walls of the driving rod 211 and the inner side walls of the adjustment base 21. The paperboard 22 is placed on the rolling bearings 214. A limiting shaft 221 is fixed on the lower side of the paperboard 22 near the front and rear sides of the side. A limiting bearing 222 is coaxially sleeved on the limiting shaft 221. The outer ring wall of the limiting bearing 222 abuts against the inner side walls of the front and rear sides of the adjustment base 21. In this way, the rolling bearings 214 can be used to realize the sliding of the paperboard 22 for left and right translation, and the limiting bearings 222 can be used to assist the left and right translation of the paperboard 22, while also limiting the front and rear translation of the paperboard 22.
