Pressure stabilizing pump for automatic hot melt adhesive coating machine

Abstract

The invention relates to the technical field of flow pumps, and discloses a pressure stabilizing pump for an automatic hot melt adhesive coating machine. The pressure stabilizing pump comprises a pumpbody cover, wherein a fixing flange is arranged on the outer surface of the bottom of the pump body cover, an air pressure inserting pipe is arranged on the position, located on the outer surface ofthe bottom of the pump body cover, of the inner side of the fixing flange, a positioning plate is arranged on the position, located on the inner side of the pump body cover, of the outer surface of the top of the air pressure inserting pipe, an air bag is arranged on the position, located on the inner side of the air pressure inserting pipe, of the outer surface of the bottom of the positioning plate, a first sliding plate is arranged on the position, located on the inner side of the pump body cover, of the outer surface of the top of the positioning plate, an extendable pipe is arranged on the position, located inside the pump body cover, of the outer surface of the top of the first sliding plate, and a second sliding plate is arranged on the position, located on the inner side of the pump body cover, of the outer surface of the top of the extendable pipe. According to the pressure stabilizing pump for the automatic hot melt adhesive coating machine, through the principle that heat inside the hot melt adhesive coating machine is reduced while air pressure is reduced in the using process, gas inside the pressure stabilizing pump is compressed to be conveyed so as to achieve the pressure stabilizing effect.

Description

technical field [0001] The invention relates to the technical field of flow pumps, in particular to a pressure stabilizing pump for an automatic hot melt adhesive coating machine. Background technique [0002] Hot-melt adhesive coating equipment is a kind of hot-melt adhesive that can be melted in a solid state, and the melted adhesive that becomes liquid is transported to the adhesive coating device to coat the substrate through a pressurizing device, and it has the function of precise temperature control. It is an electromechanical equipment that integrates fluid pressurized conveying function and extrusion coating function. It also has the function of automatic control and automatic tracking of production line speed. When in use, a pressure stabilizing pump is required to stabilize the internal air pressure and maintain the stability of hot melt adhesive output. sex. [0003] The existing automatic hot melt adhesive coating machine has certain disadvantages in use. First...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides an automatic hot melt adhesive coating machine pressure stabilizing pump, which can automatically absorb the pressure according to the air pressure temperature inside the coating equipment, maintain a normal stable effect, and be used in the coating equipment According to the gradual change of the pressure, the internal pressure is increased, the stability is maintained, and the advantages of simple structure, easy installation, and low cost solve the problem that when the traditional hot melt adhesive is used too much, the internal pressure decreases, and the melt pressure often occurs. In an unstable situation, the coating coverage of the product is not comprehensive enough after the air pressure is insufficient, which affects the quality of the subsequent product, resulting in a lower and lower amount of subsequent melt, which requires manual repair, which is time-consuming and laborious, and the method of replenishing pressure is complicated. Supplementary pressure, the structure is complex, and it needs to be calculated according to the internal pressure to perform accurate pressure supplementation, which greatly increases the cost
