It should be understood that the specific embodiments described herein are only used to explain the present invention, but are not intended to limit the present invention.

[0025] Reference Figure 1-5 The utility model provides a quantifiable glue supply device for hot melt adhesive production, including a transfer box 1, an extrusion piece 2, a spiral component 3 and a control opening 4.

[0026] The bottom of the transfer box 1 is connected to a control opening 4, which is opened and closed by controlling the opening 4. The control opening 4 comprises a housing 41, a control panel 42, and a rotary motor 43. The housing 41 is connected to the bottom of the transfer box 1. A partition 411 is provided within the housing 41, which is provided with a plurality of first glue outlets 412. The control panel 42 is located below the partition 411 and connected to the partition 411 via the rotary motor 43. The control panel 42 is provided with second glue outlets 421 corresponding to the first glue outlets 412. Rotating the control panel 42 controls the alignment of the first and second glue outlets 412, thereby controlling the opening and closing of the first glue outlet 412. An external hot melt adhesive pipe is connected to the bottom of the transfer box 1. The extrusion piece 2 is engaged with the transfer box 1, and a sealing ring 22 is provided around the side of the extrusion piece 2 closest to the transfer box 1. A spiral assembly 3 connects the extrusion 2 and the transfer box. First extension plates 21 are provided on both sides of the extrusion 2, while second extension plates 12 are provided on both sides of the transfer box 1. Two sets of spiral assemblies 3 are provided, with one end of a single spiral assembly 3 resting on the second extension plate and the other end engaging with the first extension plate 21. Rotating the spiral assembly 3 controls the extrusion 2 to descend or ascend, which in turn controls the rotation of the spiral assembly 3, allowing the extrusion 2 to penetrate deeper into the transfer box 1. An observation window 11 is provided on the sidewall of the transfer box 1. From the inside out, the sidewalls of the transfer box 1 comprise a covering layer 13, a heating layer 14, and a support layer 15. The covering layer 13 is made of a metal with good ductility and a high melting point, such as aluminum. The heating layer 14 is connected to an external circuit to heat the interior of the transfer box 1. The support layer 15 is made of a material with a certain hardness.

[0027] Working principle: The glue supply device is set between the stirring barrel and the glue spray port. The stirring barrel injects a preset height of hot melt glue into the transfer box 1, and then starts the control opening 4 to open and cooperate with the spiral component 3 to press the extruder 2 downward, so that the hot melt glue in the transfer box 1 is discharged to the glue spray port. When the hot melt glue is not fluid enough, the heating layer 14 is started to heat the transfer box 1.
