A distributing glue spraying structure for wrapping paper tape

Abstract

The invention relates to a distributive glue spraying structure for packaging paper tapes. A plurality of paths of glue outlets are arranged on a glue distributor; a glue receiving groove with an upward opening is arranged below the glue distributor; a plurality of layers of packaging paper tapes which are horizontally arranged at intervals transversely pass from the upper part of the opening of the glue receiving groove; the structure comprises two rightward falling U-shaped frames with opposite openings; each frame is formed by connecting both upper and lower cross sections into one whole body by a vertical section; one frame can horizontally rotate around the other frame; a plurality of horizontal glue spraying pipes are fixed at intervals on the vertical section of the rotating frame from top to bottom; a plurality of horizontal flow passing pipes are fixed at intervals on the vertical section of the fixed frame from top to bottom; and the flow passing pipes are connected with the corresponding glue spraying pipes by elastic hoses. The device is uniform and smooth to discharge glue and does not require an additional glue scrapping rod to carry out glue scrapping treatment; a glue spraying port is difficult to block and the production efficiency is improved; and the glue spraying port can rotate around above the paper tapes, the glue distributor does not need to be closed in the process of cleaning the glue spraying port, the distributive glue spraying structure is beneficial to long-term use of equipment, and the cleaning step is simple and convenient.

Description

Technical field [0001] The invention relates to the field of product packaging, in particular to a glue-spreading structure for packaging paper tapes. Background technique [0002] Before using long paper tape to package industrial products, glue is usually applied to one side of the paper tape. This process is called "gluing". The packaging of medium and large steel products requires longer paper tapes. Generally, paper tapes are several meters to tens of meters long. In order to ensure the efficiency of long tapes, it is usually completed by mechanized glue spraying devices. [0003] At present, a common glue spraying structure is that the glue dispenser has multiple glue outlets, each outlet is equipped with a valve, and the glue dispenser is arranged below the glue dispenser with an upward glue receiving tank, and the bottom of the glue is connected with the glue through a return pump Distributor, the packaging paper tapes arranged horizontally and horizontally pass through th...

Problems solved by technology

[0005] 1. Glue is a viscous liquid. Due to the narrow and long opening of the glue application port, it is easy to cause the glue to flow unsmoothly. Some places have too much glue applied to the wrapping paper tape, and some places have too little or no glue, resulting in uneven glue application. ; Therefore, in order to ensure the quality of packaging, it is necessary to arrange glue scraping sticks in pairs on the output side of the glue spraying structure. , scrape the glue stick on the paper tape evenly;

[0006] 2. Glue is a viscous liquid. Since the opening of the glue application port is narrow and long, and it is located at the bottom of the glue application tube, where the cross-section pressure of the application tube is the highest, when the glue does not flow smoothly, the glue application port on the bottom of the application tube is prone to glue Blockage, if the blockage is not cleared in time, the glue will gradually condense into a ball inside and outside the glue application port, resulting in the blockage or even scrapping of the entire glue application pipe;

[0007] 3. The positions of the wrapping paper tape and the glue application tube are fixed and cannot be moved. Once the glue blocks the glue application port, the glue application port can only be cleaned by closing the multi-way valve on the glue dispenser to avoid a large amount of glue gushing out during the cleaning process. The glue outlet pollutes the paper surface of the packaging tape. After cleaning, open the valves and continue to apply glue. Due to the clogging, there are 3 to 7 incidents per day on average. Frequent switching valves are not only cumbersome to operate, but also cause long-term use. Damaged valves, increased equipment operating costs, and inefficient dispensing
