Description

Technical Field

[0001] This utility model relates to the field of epoxy resin glue gun technology, specifically to an extrusion device for epoxy resin glue. Background Technology

[0002] In the processing of epoxy resin adhesives, existing extrusion devices often face several challenges. Because epoxy resin adhesives tend to solidify at low temperatures, this can lead to blockage of the extrusion barrel or tube, affecting extrusion efficiency and quality. Furthermore, existing extrusion devices may lack effective heating and stirring mechanisms during extrusion, resulting in insufficiently uniform mixing of the epoxy resin adhesive, further impacting the extrusion effect. To address these issues, this patent proposes an extrusion device for epoxy resin adhesives. Utility Model Content

[0003] The purpose of this utility model is to provide a technical solution for an extrusion device for epoxy resin adhesives, thereby overcoming the shortcomings mentioned in the background art. To address the drawbacks and defects described in the background art, this technical solution includes the following:

[0004] The device includes a glue gun mechanism, with a glue cartridge heating and softening mechanism at the left end of the glue gun mechanism. The glue gun mechanism includes a square frame, a handle fixed to the rear side of the square frame, a trigger hinged between the square frame and the handle, a push rod running through the interior of the square frame, a push plate surrounding the outer ring of the push rod, the front end of the trigger contacting the push plate, a pushing disc connected to the left end of the push rod, support bars connected to the front and rear side walls of the square frame, a ring fixed to the left end of the support bar, and a glue cartridge held between the ring and the pushing disc.

[0005] The rubber tube heating and softening mechanism includes two arched plastic blocks arranged symmetrically, a metal jacket fixed between the arched plastic blocks, and an electric heating plate embedded and fixed inside the metal jacket. Thermally conductive silicone is fixed on the side of the metal jacket that is close to each other, and the side of the thermally conductive silicone that is close to each other contacts the left side of the outer ring of the rubber tube. Spring locks are connected to the front and rear sides of the arched plastic blocks.

[0006] As a preferred embodiment of this utility model: battery compartments are fixed on the surfaces of the arched plastic blocks that are far apart from each other, and cylindrical batteries are snapped into the inside of the battery compartments.

[0007] As a preferred embodiment of this utility model: a controller for controlling the cylindrical battery to supply power to the electric heating plate is provided on the outer surface of the arched plastic block.

[0008] As a preferred embodiment of this utility model: the interior of the metal jacket is provided with a cavity in which a power supply heating plate is embedded and fixed.

[0009] As a preferred embodiment of this utility model: grooves are provided on the surfaces of the thermally conductive silicone tubes that are close to each other, for coupling and contact with the outer surface of the tube.

[0014] This solution incorporates a cartridge heating and softening mechanism on the glue gun. The electric heating plate of this mechanism rapidly heats the cartridge, providing uniform and stable heat to the epoxy resin, effectively preventing uneven resin properties caused by localized overheating or underheating. The thermally conductive silicone, fixed to the metal jacket on one side, adheres tightly to the outer surface of the cartridge due to its soft texture. Even with slight shape deviations in the cartridge, the grooves on the adjacent sides of the silicone, coupled with the curvature of the cartridge's outer surface, ensure good heat conduction. This allows the epoxy resin to soften uniformly, reducing the possibility of localized hardening or clumping due to uneven temperature and preventing blockages during extrusion.

[0023] The following description is exemplary in nature and is not intended to limit the scope, application, or use of this disclosure. It should be understood that in all these figures, the same or similar reference numerals indicate the same or similar parts and features. The figures are merely schematic representations of the concept and principles of embodiments of this disclosure and do not necessarily show the specific dimensions and scale of each embodiment. Specific details or structures of embodiments of this disclosure may be exaggerated in particular portions of certain figures. The disclosures of various publications, patents, and published patent specifications cited herein are incorporated herein by reference in their entirety. The technical solutions of this utility model will be clearly and completely described below in conjunction with embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model.

[0024] Example 1: This extrusion device mainly consists of a glue gun mechanism 1 and a glue cartridge heating and softening mechanism 2. The square frame 11 of the glue gun mechanism 1 is made of high-strength plastic, and an ergonomic handle 16 is fixed to its rear side. The trigger 17 is connected between the square frame 11 and the handle 16 through a hinge structure, allowing for flexible operation. The push rod 18 passes through the interior of the square frame 11, and the push plate 13 sleeved on its outer ring contacts the front end of the trigger 17. When the trigger 17 is pulled, the push plate 13 can slide along the push rod 18. The pushing disc 113 connected to the left end of the push rod 18 contacts two glue cartridge push rods 19, which are used to assist in pushing the glue in the glue cartridge 111. A ring 110 is fixed to the left end of the support bar 112 on the front and rear side walls of the square frame 11. The glue tube 111 is clamped between the ring 110 and the pushing disc 113. The glue outlet of the glue tube 111 passes through the inside of the ring 110 to ensure smooth glue dispensing. A cylindrical spring 12 is provided between the inner side wall of the square frame 11 and the left side wall of the push plate 13, and is sleeved on the outer ring of the push rod 18. When the trigger 17 is released, the cylindrical spring 12 can reset the push plate 13. A pressure relief plate 15 is clamped at the right end of the square frame 11. A conical spring 14 is connected between the left side wall of the pressure relief plate 15 and the right side wall of the square frame 11, and is sleeved on the outer ring of the push rod 18 to buffer the pressure during the pushing process. A metal sleeve 25 is fixed between two symmetrically arranged arched plastic blocks 21 of the glue cartridge heating and softening mechanism 2. An electric heating plate 26 is embedded and fixed inside the metal sleeve 25. Thermally conductive silicone 27 is fixed to the side of the metal sleeve 25 that is close to each other. The side of the thermally conductive silicone 27 that is close to each other contacts the left side of the outer ring of the glue cartridge 111, so as to heat and soften the epoxy resin glue inside the glue cartridge 111. Spring locks 24 are connected to the front and rear sides of the arched plastic blocks 21 to facilitate the installation of the glue cartridge heating and softening mechanism 2 on the glue gun mechanism 1.

[0025] Example 2: Based on Example 1, battery compartments 22 are fixed to the surfaces of the arched plastic blocks 21 that are far apart from each other. Cylindrical batteries 23 are snapped into the battery compartments 22 to provide power to the heating plate 26. A controller is provided on the outer surface of the arched plastic blocks 21. The controller can control the on / off supply of power from the cylindrical batteries 23 to the heating plate 26 and adjust the heating temperature to meet the heating requirements of different epoxy resin adhesives. The metal jacket 25 has a cavity inside for the heating plate 26 to be embedded and fixed, ensuring the heating plate 26 is firmly installed and improving the stability and uniformity of heating. Grooves are provided on the surfaces of the thermally conductive silicone rubber 27 that are close to each other. These grooves are in arc-coupled contact with the outer surface of the rubber sleeve 111, increasing the contact area between the thermally conductive silicone rubber 27 and the rubber sleeve 111, improving heat conduction efficiency, and allowing the epoxy resin adhesive inside the rubber sleeve 111 to soften more quickly.

[0026] Example 3: The extrusion device structure in this example is similar to that in Example 2, but some details have been optimized. The square frame 11 of the glue gun mechanism 1 is made of lightweight alloy material, which reduces the overall weight while ensuring strength, making it convenient for operators to use for extended periods. The handle 16 is covered with a non-slip rubber sleeve, further improving the comfort and stability of operation. A damping device is provided at the hinge of the trigger 17, making the operation of the trigger 17 smoother and preventing jamming or shaking when pulling the trigger 17. The surfaces of the push rod 18 and the push disc 113 are specially treated to have a low coefficient of friction, reducing resistance during the push process. The arched plastic block 21 of the glue cartridge heating and softening mechanism 2 is made of high-strength engineering plastic, which has good heat resistance and insulation, ensuring safety during use. The electric heating plate 26 uses a high-efficiency and energy-saving heating element, which can quickly heat up and maintain a stable working temperature, improving heating efficiency. The thermally conductive silicone 27 is made of high-quality thermally conductive material, which has good flexibility and thermal conductivity, and can closely fit the outer surface of the glue cartridge 111 to achieve efficient heat conduction.

[0027] Example 4: Based on Example 3, the installation and fixing method of the glue cylinder 111 was improved. Elastic rubber pads are provided on the inner walls of both the ring 110 and the pushing disc 113. When the glue cylinder 111 is clamped between the ring 110 and the pushing disc 113, the elastic rubber pads can tightly fit the outer surface of the glue cylinder 111, increasing the stability of the clamping and preventing the glue cylinder 111 from slipping during the pushing process. Simultaneously, a detachable glue nozzle cap is provided at the glue outlet of the glue cylinder 111. When the extrusion device is not in use, the glue nozzle cap can be placed on the glue outlet to prevent glue from flowing out and dust from entering the glue cylinder 111. Furthermore, a transparent observation window is provided on the square frame 11, allowing the operator to observe the remaining amount of glue in the glue cylinder 111 in real time for timely replacement.

[0028] Based on the above-described preferred technical solution, the workflow of this technical solution is explained as follows: Prepare a glue cartridge 111 containing epoxy resin glue, place the glue cartridge 111 into the glue gun mechanism 1, and pass the glue dispensing nozzle of the glue cartridge 111 through the inside of the ring 110, so that the glue cartridge 111 is positioned between the ring 110 and the pushing disc 113. At this time, the right side of the glue cartridge 111 is in contact with the two glue cartridge push rods 19, and the glue cartridge push rods 19 assist in positioning the glue cartridge 111. Next, install the glue cartridge heating and softening mechanism 2 on the left end of the glue gun mechanism 1, and fix it using the spring locks 24 on the front and rear sides of the arched plastic block 21, so that the heat-conducting silicone 27 fixed on the side of the metal jacket 25 that is close to each other is in contact with the left side area of ​​the outer ring of the glue cartridge 111. Since the heat-conducting silicone 27 has a groove on the side surface that is close to each other that is in arc coupling contact with the outer surface of the glue cartridge 111, it can better fit the glue cartridge 111. A battery compartment 22 is fixed to one side of the arched plastic block 21 that is far apart from each other, and a cylindrical battery 23 is snapped into the battery compartment 22. A controller is set on the outer surface of the arched plastic block 21. The controller controls the cylindrical battery 23 to supply power to the electric heating plate 26 embedded and fixed inside the metal jacket 25. The electric heating plate 26 starts to heat up, and the heat is transferred to the glue tube 111 through the thermally conductive silicone 27, which heats and softens the epoxy resin glue inside the glue tube 111.

[0029] When the colloid needs to be extruded, the operator holds the handle 16 and pulls the trigger 17, which is hinged between the square frame 11 and the handle 16. The front end of the trigger 17 pushes the push plate 13, which is sleeved on the outer ring of the push rod 18, to slide to the left along the push rod 18. The push plate 13 drives the push rod 18 to move to the left, and the pushing disc 113 connected to the left end of the push rod 18 moves to the left accordingly. The pushing disc 113 pushes the colloid in the colloid cartridge 111, causing the colloid to be extruded from the dispensing end of the colloid cartridge 111. During the process of pulling the trigger 17 to make the push plate 13 slide to the left, the cylindrical spring 12, which is sleeved on the outer ring of the push rod 18 between the inner side wall of the square frame 11 and the left side wall of the push plate 13, is compressed. When the trigger 17 is released, the elastic force of the cylindrical spring 12 causes the push plate 13 to return to the right. Meanwhile, the pressure relief plate 15, which is fitted onto the outer ring of the push rod 18 and is held at the right end of the square frame 11, has a conical spring 14 fitted onto the outer ring of the push rod 18 between its left sidewall and the right sidewall of the square frame 11. During the push-up process, the pressure relief plate 15 is compressed, which can buffer the pressure during the push-up process. When the push-up ends, the pressure relief plate 15 is reset by the elastic force of the conical spring 14. By repeatedly operating the trigger 17 in this way, the epoxy resin can be continuously extruded.

[0030] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
