Bonding agent coating device

Abstract

A bonding agent coating device is installed on bonding agent coating equipment comprising a machine base and a movement device and is used for coating of a bonding agent. The bonding agent coating device comprises a glue coating pipe, connection bases, a switch shaft, fixing supports and rotation mechanisms. The glue coating pipe is provided with a glue solution inlet and multiple coating holes. The glue coating pipe is fixed through the connection bases. The switch shaft is installed in the glue coating pipe in a sleeving manner and is provided with glue guide holes. The connection bases andthe rotation mechanisms are fixed through the fixing supports, and the fixing supports are connected with the movement device. Each rotation mechanism comprises a rotating device and a rotating shaft.The rotating devices drive the rotating shafts. The rotating shafts penetrate through the fixing supports to be connected with the end portions of the switch shaft and drive the switch shaft to rotate in the glue coating pipe, and therefore the glue solution inlet, the glue guide holes and the coating holes can be unblocked or blocked, and the aim of opening and closing the coating holes of the bonding agent coating device is achieved. By means of the bonding agent coating device, a bonding agent entry passageway and a coating passageway can be rapidly opened or closed; on one hand, the bonding agent is saved, and the production cost is reduced; and on the other hand, the product quality can be ensured, and the service life of the bonding agent coating device can be prolonged.

Description

technical field [0001] The invention relates to an adhesive coating device, in particular to an adhesive coating device used on adhesive coating equipment, and belongs to the technical field of mechanical manufacturing. Background technique [0002] In real life, many products need to be connected by adhesive bonding, including the production of various plywood, packing boxes / bags, and even the production of products such as mattresses, all of which need to be completed by bonding. [0003] Bonding is inseparable from adhesives, and for a long time, the application of adhesives was done by hand. Manual gluing has low efficiency and uneven coating. For some adhesives containing irritating ingredients or toxic and harmful ingredients, manual gluing will also cause harm to production personnel. Therefore, now, manual gluing has been basically eliminated. , replaced by a wide variety of adhesive application equipment such as: [0004] Invention patent (Application No.: 2016112...

AI Technical Summary

Problems solved by technology

[0011] In the prior art, the adhesive coating device in the adhesive coating equipment is usually only a tubular part with a plurality of coating holes, and the adhesive is introduced from the external pipe connected to the tubular part, and the control The switch axis of adhesive flow and flow rate is set on the introduction pipe or tubular part. When the adhesive is to be closed after gluing, since the coating hole on the tubular part cannot be blocked directly, the remaining in the tubular part The adhesive will also flow out from the coating hole under the action of gravity, so that, on the one hand, the adhesive will be wasted, and on the other hand, the adhesive trapped in the tubular part will solidify, blocking the coating hole or even The entire tubular part will affect the normal use of the next time; on the other hand, the adhesive that continuously flows out from the coating hole will cause local uneven coating of the adhesive, thereby affecting product quality and causing economic losses
