Description

Technical Field

[0001] This utility model relates to the field of dispensing head technology, specifically a dispensing head for dispensing structural adhesive. Background Technology

[0002] Structural adhesives are adhesives with high strength, capable of withstanding large loads, and resistant to aging, fatigue, and corrosion. They also exhibit stable performance within their expected lifespan and are suitable for bonding structural components that bear strong forces. Structural adhesives are widely used in engineering, mainly for the reinforcement, anchoring, bonding, and repair of components. After the structural adhesive is produced, it needs to be packaged through a discharge head.

[0003] Currently, conventional dispensing heads are mostly controlled by opening and closing the first solenoid valve, which results in the dispensing head being unable to dispense quantitatively. In addition, the dispensing head lacks heating function, and the structural adhesive inside the dispensing head is prone to solidification, causing blockage. Furthermore, the dispensing head is not easy to disassemble and clean, and the residual structural adhesive inside the dispensing head is prone to solidification, requiring disassembly, cleaning, or replacement, which is not conducive to use. Therefore, we propose a dispensing head for dispensing structural adhesive to solve the above problems. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example like Figures 1-3 As shown in the figure, an embodiment of the present invention provides a dispensing head for dispensing structural adhesive, including a dispensing cylinder 1. A feeding mechanism 2 is installed on the upper side wall of the dispensing cylinder 1 near the left side. A driving mechanism 3 is installed on the right side wall of the dispensing cylinder 1. A dispensing mechanism 4 and a temperature controller 5 are installed on the left edge of the lower side wall of the dispensing cylinder 1. A plug 6 is threaded on the left side of the dispensing cylinder 1, and a liquid inlet mechanism 7 is installed on the plug 6.

[0018] like Figure 3 As shown, in some embodiments, the dispensing cylinder 1 includes an inner cylinder 101, an electric heating film 102, a heat insulation film 103, and an outer cylinder 104. The electric heating film 102 is threadedly installed on the lower surface of the inner cylinder 101, and the heat insulation film 103 is provided on the outer surface of the electric heating film 102. The outer cylinder 104 is fixedly installed on the outer surface of the heat insulation film 103.

[0019] In this embodiment, the inner cylinder 101 is used for dispensing structural adhesive, the heating film 102 can heat the structural adhesive inside the inner cylinder 101, and the heat insulation film 103 and the outer cylinder 104 reduce heat loss.

[0020] like Figure 2 As shown, in some embodiments, a circular hole 8 is provided on the left side wall of the inner cylinder 101 at a position corresponding to the liquid inlet mechanism 7, and the left side of the inner cylinder 101 is in contact with the right side of the plug 6.

[0021] In this embodiment, the circular hole 8 allows the cleaning fluid to be injected into the liquid inlet mechanism 7.

[0022] like Figure 3 As shown, in some embodiments, the left side of the outer cylinder 104 is an open structure.

[0023] In this embodiment, the left side of the outer cylinder 104 is convenient for the installation of the plug 6, and the plug 6 can be disassembled and installed to clean the inside of the dispensing cylinder 1.

[0024] like Figure 2 As shown, in some embodiments, the feeding mechanism 2 includes a feeding pipe 201 and a first solenoid valve 202. The feeding pipe 201 is fixedly installed on the upper left edge of the dispensing cylinder 1, and the first solenoid valve 202 is installed on the feeding pipe 201.

[0025] In this embodiment, the first solenoid valve 202 is opened, allowing the structural adhesive in the storage tank to flow into the inner cylinder 101 through the feed pipe 201.

[0026] like Figure 2 As shown, in some embodiments, the drive mechanism 3 includes an electric telescopic rod 301, a piston disc 302, and an air guide pipe 303. The electric telescopic rod 301 is fixedly installed on the right side of the dispensing cylinder 1. The piston disc 302 is fixedly installed on the left side of the output shaft of the electric telescopic rod 301. The piston disc 302 is movably installed in the inner cylinder 101, and the piston disc 302 matches the inner diameter of the inner cylinder 101. The air guide pipe 303 is embedded in the left side wall of the dispensing cylinder 1 near the lower side.

[0027] In this embodiment, the output shaft of the electric telescopic rod 301 drives the piston disc 302 to move to the right in the inner cylinder 101, which causes the structural adhesive in the storage box to flow into the inner cylinder 101 through the feed pipe 201. According to the stroke of the output shaft of the electric telescopic rod 301, a relatively measured amount of structural adhesive can be extracted. Then, the output shaft of the electric telescopic rod 301 drives the piston disc 302 to move to the left in the inner cylinder 101, and the piston disc 302 pushes the structural adhesive in the inner cylinder 101 toward the discharge mechanism 4.

[0028] like Figure 2 As shown, in some embodiments, the discharge mechanism 4 includes a discharge pipe 401 and a second solenoid valve 402. The discharge pipe 401 is fixedly installed on the left edge of the lower side wall of the dispensing cylinder 1, and the second solenoid valve 402 is provided on the discharge pipe 401.

[0029] In this embodiment, the second solenoid valve 402 is opened, and the structural adhesive in the inner cylinder 101 flows out through the discharge pipe 401.

[0030] like Figure 2 As shown, in some embodiments, the liquid inlet mechanism 7 includes a connecting pipe 701 and a third solenoid valve 702. The connecting pipe 701 is embedded in the plug 6, and the third solenoid valve 702 is installed on the connecting pipe 701.

[0031] In this embodiment, the connecting pipe 701 is connected to the cleaning fluid pipe on the booster pump, the third solenoid valve 702 is opened, and the high-pressure cleaning fluid flows into the inner cylinder 101 through the connecting pipe 701 to clean the inner cylinder 101. The residue in the inner cylinder 101 and the cleaning fluid are then discharged through the discharge pipe 401, achieving the cleaning effect of the inner cylinder 101 and the discharge pipe 401.

[0032] In use, the feed pipe 201 in the feeding mechanism 2 is connected to the outlet of the storage tank, opening the first solenoid valve 202. The output shaft of the electric telescopic rod 301 in the drive mechanism 3 drives the piston disc 302 to move to the right within the inner cylinder 101, causing the structural adhesive in the storage tank to flow into the inner cylinder 101 through the feed pipe 201. Based on the stroke of the output shaft of the electric telescopic rod 301, a relatively measured amount of structural adhesive is extracted. After extraction, the first solenoid valve 202 closes, opening the second solenoid valve 402 in the discharge mechanism 4. The output shaft of the electric telescopic rod 301 then drives the piston disc 302 to move to the left within the inner cylinder 101, extruding the structural adhesive from the inner cylinder 101 through the discharge pipe 401. During this process, the temperature controller 5 monitors the temperature of the structural adhesive in the inner cylinder 101 and controls the flow of the electric telescopic rod 301. The heating film 102 heats the internal structural adhesive of the inner cylinder 101. After dispensing, the first solenoid valve 202 is closed and the second solenoid valve 402 is opened. The piston disc 302 is located on the rightmost side of the inner cylinder 101. The connecting pipe 701 in the liquid inlet mechanism 7 is connected to the cleaning liquid pipe on the booster pump. The third solenoid valve 702 is opened, and the high-pressure cleaning liquid flows into the inner cylinder 101 through the connecting pipe 701 to clean the inner cylinder 101. The residue in the inner cylinder 101 and the cleaning liquid are then discharged through the discharge pipe 401, achieving the cleaning effect of the inner cylinder 101 and the discharge pipe 401. This enables quantitative dispensing through the discharge head, making the dispensing dosage more accurate. At the same time, the heating function of the dispensing cylinder 1 is added, making it less likely for the structural adhesive inside the dispensing cylinder 1 to solidify. The cleaning function of the dispensing mechanism 4 is also added, preventing the dispensing mechanism 4 from solidifying and clogging, which is beneficial for use.

[0033] In summary, this dispensing head for dispensing structural adhesive can achieve quantitative dispensing, making the dispensing dosage more accurate. At the same time, it adds a heating function to the dispensing cylinder 1, making it less likely for the structural adhesive inside the dispensing cylinder 1 to solidify. It also adds a cleaning function to the dispensing mechanism 4, preventing solidification and blockage, which is beneficial for use.
