specific Embodiment approach 1

[0017] Specific implementation mode one: as Figure 1 to Figure 7 As shown, the main shaft part 1, the main valve body 3, the stirring blade 51, the polyurethane A component inlet, the overflow port seat 2, the polyurethane B component inlet, the overflow port seat 17, the polyurethane A glue inlet valve 4, Polyurethane B glue feed valve 18, water cleaning valve 1, water cleaning valve 2 11, water cleaning valve 3 21, water cleaning valve 4 22, cup moving part 15, pneumatic components, glue nozzle 16, etc. The main body of the water-cleaning two-component glue applicator is fixed and integrated. When the valve needle 2 43 and valve needle 73 are opened at the same time, the glue of the two components of polyurethane A and B is continuously supplied by the metering pump, and the glue of polyurethane A and The glue inlet valve 4 and the polyurethane B glue inlet valve 18 enter the glue cavity 68 of the mixing cup of the glue applicator, and the motor or hydraulic motor drives th...

[0021] Specific implementation mode two: as figure 1 , figure 2 , image 3 , Figure 5 and Figure 7 As shown, the polyurethane component A feed port described in this embodiment, the overflow port 2, the polyurethane A glue inlet valve 4, the A glue valve seat 40, the polyurethane component inlet, the overflow port seat 17, the polyurethane B glue glue inlet valve, The stirring blade seat 102 is connected to the main valve body 3 by screws, the sealing ring 1 31, the rubber diaphragm 39 and the sealing ring 35 are installed on the relief valve needle 1 38, the sealing ring 2 32 is installed on the piston 1 34, and the valve cover 33 is fixed on the polyurethane A glue feed valve 4, the piston 34 can move left and right, the stroke adjustment screw 37 is installed on the valve cover 33, and the opening size of the overflow valve needle 38 can be adjusted by turning the stroke adjustment screw 37, thereby adjusting the overflow valve. Flow rate: the sealing ring 31 and the...

specific Embodiment approach 3

[0022] Specific implementation mode three: as figure 1 , figure 2 , image 3 As shown, the water-cleaning two-component gluing head described in this embodiment has a cup-moving structure. The cup moving structure means that the closing of the gluing nozzle 16 depends on the movement of the outer cup, so that the moving cup 57 and the conical surface of the stirring blade 51 form a sealing surface, so that the mixed glue stops flowing out of the gluing nozzle 16. The cup moving part 15 is mainly composed of sealing ring eight 52, cup body 53, retaining ring 54, sealing ring nine 55, sealing ring ten 56, moving cup body 57, sealing ring fourteen 98, sealing ring eleven 58, valve cover 59, Glue nozzle 60, air hole four 23, air hole eight 81 and plug 61 form. The compressed air communicates with air hole four 23 and air hole eight 81 respectively, and is arranged on the upper and lower sides of the protruding part of the moving cup body 57. The compressed air pushes the movin...

Abstract

The invention provides a multi-channel water cleaning double-component gluing head and relates to a multi-channel water cleaning double-component polyurethane gluing head. The multi-channel water cleaning double-component gluing head solves the problem that the conventional double-component polyurethane gluing head must be cleaned by a solvent and cannot be cleaned by water. A stirring blade base is connected with a main valve body; a sealing ring 1, a rubber film sheet and a sealing ring are arranged on an overflow valve needle 1; a sealing ring 2 is arranged on a piston 1; a valve cover is fixed on a polyurethane A glue feeding valve; the piston 1 can move leftwards and rightwards; a stroke regulating screw is arranged on the valve cover; the stroke regulating screw is in threaded connection with the valve cover; and the stroke regulating screw is rotated to adjusting the opening size of an adjusting valve needle 1, so that overflow quantity is adjusted. The multi-channel water cleaning double-component gluing head has high generality and a good mixed effect, can wash the polyurethane in the gluing head with water, and is particularly suitable for shaft-driving and cup-driving gluing heads. The multi-channel water cleaning double-component gluing head is cleaned by using the common water instead of the solvent so as to reduce production cost, save energy and reduce environmental pollution caused by the solvent.

Description

technical field [0001] The invention relates to a multi-channel water cleaning two-component polyurethane gluing head. Background technique [0002] At present, there are many types of two-component polyurethane glue applicators at home and abroad. According to the structure of the valve body switch, it can be divided into shaft drive, outer drive, and external rubber valve control valve. When the gluing head has a long working interval or stops working, in order to prevent the gluing head from being blocked, the gluing head must be cleaned frequently to clean the mixed two-component polyurethane glue in the glue chamber. The cleaning of the existing gluing head is only Solvent can be used for cleaning, and each cleaning requires a large amount of solvent, which increases production costs. Solvents pose a greater threat to the health of operators, pollute the environment, waste energy, and are flammable. Operation is also very time-consuming and laborious. At present, ther...
