[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figures 1 to 5 , a hose heating device for a glue dispensing machine, comprising:

[0024] Two metal hoses 10, both ends of which are provided with flanges;

[0025] Two end plates 2 are detachably connected to the flanges on the metal hose 10, and the end plates 2 are provided with a first through hole 201 and a plurality of second through holes 202;

[0026] A plurality of electric heating elements 3 are arranged in the metal hose 10 and both ends of the electric heating elements 3 extend out of the metal hose 10 and are connected to the second through hole 202;

[0027] A plurality of fixing devices, used for fixing the end of the electric heating element 3 in the second through hole 202;

[0028] Two temperature sensors 4 are respectively arranged on one of the metal hoses 10 for detecting the temperature inside the metal hose 10;

[0029] The controller is electrically connected to the plurality of electric heating elements 3 and the two temperature sensors 4. In the utility model, during installation, the rubber hose of the glue dispenser passes through the metal hose 10, the electric heating element 3 is placed in the metal hose 10, the end plate 2 is connected to the flange on the metal hose 10, one end of the rubber hose passes through the first through hole 201 to connect with the rubber cylinder, and the other end is connected to the glue cylinder, the end of the electric heating element 3 cooperates with the second through hole 202 to achieve the installation of the entire heating device, the glue in the two rubber cylinders flows from the rubber hose to the glue cylinder for mixing and then discharged to glue the object, when the glue flows in the rubber hose, the electric heating element 3 is powered on to heat the glue in the rubber hose, when the temperature sensor 4 senses that the temperature in the metal hose 10 exceeds the preset value, it sends a signal to the controller, the controller controls the electric heating element 3 to stop working, when the temperature sensor 4 senses that the temperature in the metal hose 10 is lower than the preset value, it sends a signal to the controller, the controller controls the electric heating element 3 to work, so that the glue is in a good state. Specifically, the electric heating element 3 is an electric heating wire; the end plate 2 is connected to the flange on the metal hose 10 by bolts.

[0030] As a preferred embodiment of the utility model, it may also have the following additional technical features:

[0031] In this embodiment, a heat insulating layer is provided on the metal hose 10 to prevent people from getting burned by touching the metal hose 10. Specifically, the heat insulating layer is made of heat insulating cotton or other heat insulating materials.

[0032] In this embodiment, the end plate 2 is provided with a plurality of threaded holes 203 which are communicated with the second through hole 202; the fixing device comprises a bolt 5 which is screwed with the threaded hole 203, and the bolt 5 is tightened so that one end thereof abuts against the electric heating element 3, thereby fixing it.

[0033] In this embodiment, two heat-resistant hoses 6 are further included, which are respectively arranged in one of the metal hoses 10. The heat-resistant hoses 6 are provided with a plurality of air holes 601. Since the hose is actually in a horizontal state or an arched state when in use, when it is in an arched state, the electric heating element 3 will contact the hose, causing damage to the hose. By setting the heat-resistant hose 6 to be sleeved on the hose, and the heat-resistant hose 6 is provided with a plurality of air holes 601, the hose is heated, and at the same time, the electric heating element 3 can be prevented from contacting the hose. Specifically, the heat-resistant hose 6 is a silicone hose, a fluororubber hose or other heat-resistant hose.
