Description

Technical Field

[0001] The present invention relates to a flow channel heating device in the field of glue dispensing, and in particular to a flow channel heating device for heating glue. Background Art

[0002] The existing technology uses a 220V power supply to heat the fluid box. When heating the flow channel module, any leakage presents a significant safety hazard to the operator. Due to the varying properties of glue, some glues experience changes in viscosity upon heating, which in turn affects the fluidity of the glue in the flow channel. The existing flow channel heating structure presents the following technical issues: Without a heating process, the poor fluidity of the unheated glue can lead to unstable dispensing, such as glue breakage, inconsistent dispensing widths, and bubbles.

[0003] In addition, in the prior art, the adjusting nut is connected by a thread and cannot be screwed to the bottom. The adjusting nut is tightened by pressing the nozzle with a firing pin. However, when in operation, the firing pin may move back and forth and there may be a state where the firing pin is away. In this state, the adjusting nut is at risk of loosening, resulting in unstable operation of the flow channel module.

[0004] The existing technology has at least the following defects: First, the flow channel module uses a voltage of 220V, which poses a safety hazard to the operator; second, it cannot provide real-time feedback to adjust the heating temperature and cannot control the fluidity of the glue; local heating results in poor glue dispensing; third, the adjusting nut is easy to loosen, and the flow channel module cannot work stably.

[0005] In view of this, designing a flow channel heating device that is safe to operate, automatically controls the heating temperature in real time to control the viscosity of the glue, and makes it achieve optimal fluidity and more stable operation is a technical problem that needs to be solved urgently by those skilled in the art.

[0035] However, it should be understood that the present invention is not limited to the embodiments described below, and the technical concept of the present invention can be implemented in combination with other well-known technologies or other technologies with the same functions as those well-known technologies.

[0036] In the following description of specific embodiments, in order to clearly demonstrate the structure and working mode of the present invention, a number of directional words will be used for description, but words such as "front", "rear", "left", "right", "outside", "inside", "outward", "inward", "axial", and "radial" should be understood as convenient terms and should not be understood as restrictive terms.

[0037] The structural diagram of the heating module and the flow channel module is described in conjunction with the accompanying drawings. Figure 1 The schematic diagram of the structure of the heating module provided by the present invention. The heating module 1 includes a heating base 11, on which is provided an adapter heat insulation base 14, on the upper end of which is installed a corrugated hose 15, which is used to place the wires of the heating rod and thermocouple in the heating module 1, and a connector mounting base 16 connected to the corrugated hose 15, which is equipped with a docking plug 17, which is connected to the heating controller, and a through hole 12 and an anti-loosening mechanism 13 are provided at the bottom of the heating base 14, one end of the anti-loosening mechanism 13 is in an arc structure forming a part of the through hole 12, and the other end of the anti-loosening mechanism 13 is in a rectangular shape, and the anti-loosening mechanism 13 is flush with the surface of the heating base 11 and there is a gap between the heating bases 11 on both sides.

[0038] The heating base 11 is concave in shape, with a raised baffle 18 disposed on one side of the heating base 11, parallel to the adapter heat insulation base 14. The heating base forms a structure that surrounds the flow channel module 2 on three sides, which can heat the colloid in the flow channel module 2 more evenly and avoid local temperature differences that may lead to poor dispensing.

[0039] Figure 2 The present invention provides Figure 1 Top view of the heating module; wherein, one end of the anti-loosening mechanism 13 is connected to the heating base 11, so that the anti-loosening mechanism 13 is fixed to the heating base 11. At the same time, when the anti-loosening mechanism 13 is moved in the gap by an external force, it is guaranteed that the anti-loosening mechanism 13 can return to its original position after the external force applied to the anti-loosening mechanism 13 is removed. There is a gap between the anti-loosening mechanism 13 and the heating base 11, which allows the anti-loosening mechanism 13 to move in a direction perpendicular to the baffle 18 when subjected to an external force. When the adjusting nut 21 in the flow channel module 2 is installed in the through hole 12, the anti-loosening mechanism 13 can hold the adjusting nut 21 tightly when subjected to an external force, so that the adjusting nut 21 can operate more stably.

[0040] Figure 3 A schematic diagram of the structure of the heating base part A provided by the present invention; Figure 3 The structural relationship between the anti-loosening mechanism 13 and the heating base 11 can be more clearly understood. There are gaps 41 and 42 between the anti-loosening mechanism 13 and the heating base 11. Gap 41 is a gap near the outside of the heating base 11. Gap 41 includes a circular arc section and a rectangular section. Gap 42 overlaps with the diameter of the through hole 12, ensuring that the adjusting nut 21 is gripped by the anti-loosening mechanism 13 over a larger area. The width of gap 41 is smaller than the width of gap 42. Those skilled in the art can also adjust the width of the gap and the length of the circular arc section of the loosening mechanism 13 as needed.

[0041] Figure 4 Schematic diagram of the heating module structure provided by the present invention Figure 2 ; Adapter thermal insulation seat 14, corrugated hose 15, connector mounting seat 16, the adapter thermal insulation seat 14 is fixed on the heating base 11, and the corrugated hose 15 is installed between the adapter thermal insulation seat 14 and the connector mounting seat 16. The corrugated hose 15 is connected to the heating base 11 and is used to place the wires in the heating base 11 for controlling the thermocouple and heating rod. The corrugated hose 15 can choose to use a metal corrugated hose to protect the heating rod and thermocouple outlet wires and prevent the outlet wires from being worn and damaged during use, causing danger. The heating rod and thermocouple are installed in the heating base 11, and the voltage of the heating rod is 24V and the power is 40W. The docking plug 17 is fixed on the connector mounting seat 16, and the docking connector 17 is electrically connected to a heating controller. The connector mounting seat is designed with an annular pattern. The annular pattern design of the connector mounting seat 16 makes it convenient for the operator to plug and unplug the docking connector.

[0042] The heating controller can control the heating temperature of the heating base 11 in real time, thereby controlling the temperature around the flow channel module 2 and the fluidity of the glue. According to the characteristics of the glue, the heating temperature required for the glue is set in advance. When the heating controller is powered on, the heating rod is heated up, and the thermocouple measures the temperature of the heating base. The detected temperature is fed back to the heating controller. Through the thermocouple temperature measurement feedback, when the detected temperature reaches the target temperature, the heating is stopped and stabilized at the target temperature to achieve the best fluidity of the glue. Among them, the heating controller includes a temperature detection module, which can adjust the heating temperature of the glue in real time by detecting the temperature of the glue, so as to make the fluidity of the glue better. This avoids poor fluidity of the glue when it is not heated and the occurrence of unstable glue dispensing during the dispensing process, such as glue breakage, inconsistent glue dispensing width, and glue dispensing bubbles.

[0043] Figure 5 Schematic diagram of the flow channel module structure provided by the present invention Figure 1 ; Figure 6 A top view of the flow channel module structure provided by the present invention; the flow channel module 2 includes a glue inlet 22, an adjusting nut 21, a flow channel fixing part 23, the flow channel base matches the flow channel heating base 11, and the flow channel module 2 is placed in the concave area formed by the flow channel heating base 11.

[0044] Figure 7 The present invention provides Figure 6Cross-sectional view along the AA direction; the flow channel module 2 also includes a glue flow channel, which connects the glue inlet 22 and the glue outlet 24. The adjusting nut 21 is connected by a thread and will not be screwed to the bottom. The nozzle is pressed against the firing pin to achieve tightening. However, in the working state, the firing pin may move back and forth and there may be a state where the firing pin is away. In this state, the adjusting nut is at risk of loosening without other auxiliary tightening structures. Therefore, in the present invention, an anti-loosening mechanism 13 is provided in the flow channel heating module 1, which is used to tighten the adjusting nut 21 during operation to prevent the nut from loosening during long-term operation of the flow channel heating device, thereby affecting the operation of the flow channel module 2.

[0046] Compared with the prior art, the present invention has the following advantages: First, the anti-loosening mechanism holds the adjusting nut tightly to prevent the adjusting nut from loosening in the working state, so that the runner module works more stably; second, when the heating controller is powered on, the heating rod heats up, and through the thermocouple temperature measurement feedback, heating is stopped when the target temperature is reached and stabilized at the target temperature, thereby controlling the fluidity of the glue and achieving the optimal fluidity of the glue; third, the runner module and the heating module are in contact on three sides, so that the runner module is heated more evenly.
