Description

Technical Field

[0001] The utility model relates to a paper tube glue heating device, belonging to the technical field of hot glue equipment. Background Art

[0002] During the production of paper tubes, a large amount of glue is used. This glue needs to be heated before use to increase its viscosity so that it can be used better. The current heating equipment is to put the glue barrel into a heating box for water bath heating before use, but this is more troublesome and the hot glue effect is not good, which affects subsequent use. Utility Model Content

[0003] The utility model provides a paper tube glue heating device, which solves the problem that the current device is troublesome to heat the glue, the hot glue effect is poor, and the subsequent use is affected.

[0004] The utility model relates to a paper tube glue heating device, comprising an outer shell, an inner barrel being arranged in the outer shell, a heating rod being fixed in the middle of the inner barrel, an inner hot glue spiral coil being arranged on the outer side of the heating rod, an outer hot glue spiral coil being arranged on the outer side of the inner hot glue spiral coil, an upper connecting head and a lower connecting head being connected to the upper and lower ends of the inner hot glue spiral coil and the outer hot glue spiral coil respectively, the upper connecting head and the lower connecting head being fixed on the inner barrel, the upper connecting head and the lower connecting head being connected to a glue outlet pipe and a glue inlet pipe respectively, and the outer ends of the glue outlet pipe and the glue inlet pipe passing through the outer shell.

[0005] A water inlet pipe and an air outlet pipe are fixed on the top of the inner barrel, and a drain pipe is fixed on the bottom of the inner barrel, which is convenient for replacing the water in the inner barrel.

[0006] The top of the outer shell has a mounting hole, into which an expansion pot is fixed. The bottom of the expansion pot is connected to the top of the inner barrel via a pipe. When the water in the inner barrel heats up, the steam generated will enter the expansion pot to buffer the pressure.

[0007] Support blocks are fixed at the four corners of the bottom of the shell, and anchor bolts are threaded on the support blocks to adjust the height of the device.

[0008] Handles are provided on the outer walls of the housing on both sides to facilitate moving the device.

[0009] The utility model has the following beneficial effects:

[0010] The glue can be transported into the hot glue inner spiral coil and the hot glue outer spiral coil arranged in the inner barrel for heating, thereby realizing flow heating, having better heating effect, faster heating speed and improving hot glue efficiency.
