Multi-valve linkage glue-spraying device

Abstract

The invention relates to a multi-valve linking glue spraying device which comprises a shell, a glue spraying mechanism, an upper cover and a driving mechanism, wherein the upper cover is provided with a glue inlet, the driving mechanism is arranged on the upper cover, and the bottom of the shell is provided with at least two holes; the glue spraying mechanism comprises more than one connecting bar, ball-head pin valve and nozzle, the number of the ball-head pin valves is matched with the that of the nozzles, the nozzles are arranged in the holes arranged on the bottom of the shell, and the number of the nozzles is equal to the number of the holes arranged on the bottom of the shell; the connecting bar is provided with at least two ball-head pin valves, one ball-head pin valve corresponds to one nozzle, and the connecting bar is connected with the driving mechanism and is driven by the driving mechanism so as to cause the connecting bar to drive the ball-head pin valves to move along a perpendicular direction. In addition, when the connecting bar upwards moves, all the nozzles are simultaneously opened to cause glue solution to outflow from the nozzles, and the glue spraying is realized; when the connecting bar downwards moves, all the ball-head pin valves simultaneously close the nozzles, thereby the invention can achieve the purpose of synchronous and uniform glue outflow and synchronous closing.

Description

1. Technical field [0001] The invention relates to an automatic glue spraying device, in particular to a multi-valve linkage glue spraying device. 2. Background technology [0002] At present, in the operations of building materials and boards that need to be pasted on a large area at the same time, the manual method is generally used: that is, the glue is manually brushed on the pasting surface with a brush, and after brushing, it is necessary to scrape with a scraper to make the glue spread. Layers are leveled and evened before gluing. This method has the following defects: 1. Due to the manual operation, it is easy to cause local excess glue or glue leakage, and it is difficult to ensure that the glue surface is even and smooth. Most of the glue used is volatile and toxic substances. In addition, the manual operation time is long, which is easy to cause pollution and seriously affect the health of the operator, as well as affect the paste effect; 3. Because the glue used...

Problems solved by technology

This method has the following defects: 1. Due to the manual operation, it is easy to cause local excess glue or glue leakage, and it is difficult to ensure that the glue surface is even and smooth. Most of the glue used is volatile and toxic substances. In addition, the manual operation time is long, which is easy to cause pollution and seriously affect the health of the operator, as well as affect the paste effect; 3. Because the glue used in the operation is relatively expensive, and the glue The curing speed is relatively fast, so the glue that is generally brushed to the paste surface cannot be recycled, resulting in waste; 4. Because manual work is to use a brush to dip the glue in an open glue bucket, it is easy to make the glue drip on other parts of the workpiece. And because of the strong adhesiveness of the glue, the workpiece will be stained
