[0010] The further limitation of the above technical scheme is that the temperature controller comprises a thermocouple.

[0011] A further limitation of the above technical solution is that the glue bucket temperature control device also includes an alarm, which is electrically connected to the temperature controller and is used to issue an alarm signal.

[0012] A further limitation of the above technical solution is that the glue in the glue bucket is PSA glue.

[0022] The glue bucket (not shown) that needs to be heated is placed in the mounting bracket 1. The glue in the glue bucket (not shown) is PSA glue.

[0023] Mounting bracket 1 includes mounting bracket fixing frame 12 and four side plates 14.

[0024] The mounting bracket fixing frame 12 includes a bottom frame 121, a top frame 123, and four vertical rods 125.

[0025] Both the bottom frame 121 and the top frame 123 are rectangular frames of the same size, formed by four straight rods (unnumbered) connected end to end.

[0026] The plane containing the bottom frame 121 and the plane containing the top frame 123 are parallel to each other.

[0027] Four vertical rods 125 are connected between the four corners of the bottom frame 121 and the four corners of the top frame 123.

[0028] The four vertical bars 125 are perpendicular to the plane of the bottom frame 121 and the plane of the top frame 123.

[0029] The four side plates 14 are respectively installed and fixed on the four sides of the mounting bracket fixing frame 12.

[0030] Therefore, the mounting bracket 1 is rectangular in shape and also includes an opening 16 formed by four side plates 14 for placing a glue bucket (not shown).

[0031] A heating element mounting piece 142 is installed and fixed on the inner side of each side plate 14.

[0032] The heating element mounting component 142 includes a heating element bottom end snap-fit ​​component 1421, a heating element left end snap-fit ​​component 1423, and a heating element right end snap-fit ​​component 1425.

[0033] The bottom end of the heating element bottom end clip 1421 is fixed to the bottom of the inner side of the side plate 14, and the upper end forms a heating element bottom end clip groove 14212 between the inner side of the side plate 14 and the upper end.

[0035] The right end of the heating element right end snap-fit ​​1425 is fixed to the middle right side of the inner side of the side plate 14, and the left end forms a heating element right end snap-fit ​​groove 14252 between the side plate 14 and the inner side of the side plate 14.

[0036] The four heating elements 2 are all made of stainless steel and are installed on the inner sides of the four side plates 14 respectively via heating element mounting parts 142, for heating the glue bucket (not shown).

[0037] The heating element 2 is installed in the space enclosed by the bottom end latch 1421, the left end latch 1423, and the right end latch 1425 of the heating element. The bottom, left, and right ends of the heating element 2 are respectively inserted into the bottom end latch 14212, the left end latch 14232, and the right end latch 14252 of the heating element. Therefore, the heating element 2 is stably installed on the inner side of the side plate 14, that is, on the side of the mounting bracket 1.

[0038] The temperature controller (not shown) is located inside control box 5.

[0039] The temperature controller is electrically connected to the heating element 2 and is used to control the temperature of the heating element 2.

[0040] The temperature controller (not shown) includes a thermocouple 31, which is mounted on one of the heating elements 2 to detect the temperature of the heating element 2.

[0041] The specific process of temperature detection by thermocouple 31 is as follows: When the temperature is lower than the set value on the temperature sensor (not shown in the figure), the temperature control output signal activates the SSR (Solid State Relay) to control the four heating elements 2 to heat. When the temperature reaches the set value on the temperature sensor, the temperature controller disconnects the output signal of the SSR and stops heating. When the temperature exceeds the temperature control set point, an alarm is triggered and heating is stopped.

[0042] The power supply wire (not shown) for heating element 2 and thermocouple 31 is located inside control box 5. The power supply wire is protected by explosion-proof conduit (not shown, located inside control box 5) and connected to explosion-proof switch (not shown) to meet safety and environmental protection requirements.

[0043] An explosion-proof switch (not shown in the figure) is located inside the control box 5 and is electrically connected to the heating element 2, with the connecting wire connected to the explosion-proof pipe.

[0044] A temperature sensor (not shown) is electrically connected to the heating element 2 and is used to detect the temperature of the glue bucket (not shown).

[0045] An alarm (not shown) is electrically connected to the temperature controller and is used to issue an alarm signal.

[0046] In use, place the glue bucket (not shown) containing the prepared PSA adhesive into the glue bucket temperature control device of this utility model to heat the glue bucket (not shown).

[0047] This utility model has the following beneficial effects: 1. The glue bucket temperature control device of this utility model is installed on the outer shell of the glue bucket, which can heat the glue bucket, effectively ensure that the glue temperature is not affected by the external environment, maintain the stability of the glue performance, and effectively solve the abnormal glue streaks caused by excessive glue viscosity due to low glue temperature.

[0048] 2. The glue bucket temperature control device of this utility model is equipped with a thermocouple 31 for temperature detection. The thermocouple 31 is connected to the temperature controller. When the temperature reaches the set value, it can stop heating in time. When the temperature exceeds the temperature control set alarm, it outputs an alarm and stops heating.

In short, regardless of the change in number, all sides of the mounting frame 1 are equipped with side plates 14, and these side plates 14 must enclose the mounting frame 1 to ensure the heating effect. The number of heating elements 2 is changed to one or more, respectively installed on the inner side of each side plate 14. The number of heating elements 2 can be varied; heating elements 2 can be installed on all side plates 14, or only on a portion of the side plates 14, for example, one heating element 2 is installed every other side plate 14 or at equal intervals. Thermocouples 31 are installed on the heating elements 2 to detect the temperature.

[0051] As a variation of the first embodiment described above, the mounting bracket 1 is changed to a cylindrical shape.
