Description

Technical Field

[0001] This utility model relates to the field of adhesive coating equipment technology, specifically to an adhesive coating equipment with an anti-clogging structure. Background Technology

[0002] A glue applicator is a device used to apply glue or adhesive. It is commonly used in industrial production to evenly spread glue on the surface of materials to achieve bonding, sealing, or protection. In existing technology, the glue applicator head is exposed to the air. When the machine stops working, the glue adhering to the glue head can easily solidify, causing blockage. If not cleared in time, the glue will solidify inside the tube.

[0003] For example, the authorized patent document with application number CN202322612985.0 discloses a glue-applying device, which includes a rotating material carrier fixture, a fixed bracket, and a glue-applying assembly. The rotating material carrier fixture includes a rotating positioning structure, an adsorption fixing component, and a rotating driving component. The rotating positioning structure has a clearance hole, the adsorption fixing component is disposed in the clearance hole, and the rotating driving component is connected to the rotating positioning structure. The fixed bracket is located on one side of the rotating material carrier fixture. The adsorption fixing component is used to adsorb and fix the product, the rotating driving component is used to drive the rotating positioning structure to rotate, and the glue-applying assembly is used to apply glue to the side wall of the product.

[0004] The aforementioned patent addresses the issue that the glue applicator head is exposed to air, causing the glue at the head to solidify and become clogged, making it difficult to remove the glue from the tube. Therefore, we need to provide a glue applicator with an anti-clogging structure. Utility Model Content

Three side propellers are evenly distributed on the surface of the rod, and the bottom of each side propeller is provided with a bottom propeller that is adapted to the bottom of the inner wall of the tube.

[0009] Preferably, a ring body is fixedly installed on the three side propeller surfaces, and an annular groove for the rotation of the ring body is formed on the inner wall of the tube.

[0010] Preferably, the top of the tube body is provided with an abutment mechanism for sealing the top of the tube body. The abutment mechanism includes a cap, an upper ring, and a lower ring.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a glue application device with an anti-clogging structure, comprising:

[0025] The table 1, robotic arm assembly 2, tube 3, glue discharge mechanism 4 and connecting pipe 5 are provided. The top of the table 1 is equipped with tube 3 through robotic arm assembly 2. One side of tube 3 is connected to connecting pipe 5, which is connected to external glue tube. The tube 3 is equipped with glue discharge mechanism 4 to facilitate the discharge of glue inside tube 3.

[0026] The system includes a rotatable robotic arm assembly 2 on the top of the platform 1, which can adjust the height and horizontal movement of the tube body 3. A connecting pipe 5 connected to one side of the tube body 3 is used to connect with an external glue tube. The glue enters the tube body 3 through the external glue tube and is discharged from the glue outlet at the bottom of the tube body 3. The connecting pipe 5 can be controlled to open and close. A glue discharge mechanism 4 is set inside the tube body 3. For glue that has not yet cured, the glue discharge mechanism 4 completely scrapes off the residual glue on the inner wall and bottom of the tube body 3 and discharges it from the glue discharge outlet at the bottom of the tube body 3.

[0027] In this application, the robotic arm assembly 2 is implemented using existing technology. Its specific structure, drive method (such as servo motor, pneumatic or hydraulic drive) and control method (such as PLC or industrial robot control system) are all conventional designs in the field, and therefore will not be described in detail.

[0028] The glue discharge mechanism 4 includes a rod 41, side propellers 42 and a lower propeller 43. The rod 41 is rotatably installed inside the tube 3, and the upper end of the rod 41 passes through the top of the tube 3 and extends therein. Three side propellers 42 are evenly distributed on the surface of the rod 41, and the bottom of each side propeller 42 is provided with a lower propeller 43 that is adapted to the bottom of the inner wall of the tube 3.

[0029] Specifically, after the adhesive is applied, when it is necessary to drain the adhesive from the tube 3, manually rotate the rod 41 to drive the side paddles 42 and the lower paddle 43 fixed on the rod 41 to rotate synchronously. The side paddles 42 are not placed vertically on the rod 41, but at a certain angle. The three side paddles 42 are evenly distributed on the surface of the rod 41. When rotating, they are close to the inner wall of the tube 3 to scrape off the residual adhesive and prevent the adhesive from accumulating and solidifying. The adhesive in the tube 3 is discharged through the bottom outlet. Each side paddle 42 has a lower paddle 43 at the bottom, whose shape is adapted to the bottom of the inner wall of the tube 3. When rotating, it thoroughly scrapes off the adhesive deposited at the bottom of the tube to avoid blockage.

[0030] The combined design of the three side propellers 42 and the lower propeller 43 achieves full coverage of the tube wall and bottom for adhesive scraping, significantly reducing the risk of blockage caused by adhesive residue. The integrated design of the side propellers 42 and the lower propeller 43 eliminates the need for additional cleaning tools, as they can automatically remove adhesive by rotation, reducing the frequency of manual maintenance.

[0031] Three side propellers 42 are fixedly mounted with rings 6, and the inner wall of the tube 3 is provided with annular grooves 7 for the rotation of the rings 6.

[0032] Furthermore, as the three side propellers 42 rotate, they will drive the ring body 6 to rotate. The ring body 6 is located in the annular groove 7 and its rotation is adjusted to limit the rotation range of the ring body 6. The annular groove 7 is slightly larger than the ring body 6 so that the ring body 6 can float slightly in the vertical direction within the annular groove 7. In order for the anti-collision mechanism 8 to work properly, a space is reserved for the ring body 6 to float.

[0033] The top of the tube body 3 is provided with an abutment mechanism 8 for sealing the top of the tube body 3. The abutment mechanism 8 includes a cap 82, an upper ring 83 and a lower ring 81. The upper ring 83 and the lower ring 81 are both located on the surface of the rod body 41. The lower ring 81 is located inside the tube body 3. The cap 82 is threaded on the top of the surface of the tube body 3. The round hole at the top of the cap 82 is movably connected to the surface of the rod body 41. The upper ring 83 is located on the top of the cap 82.

[0034] It is worth noting that the upper ring 83 is located at the top of the tube body 3 and the lower ring 81 is located inside the tube body 3. Since the cap 82 is threadedly installed on the surface of the tube body 3, rotating the cap 82 upward will push the upper ring 83 to move, thereby driving the rod 41 and the lower ring 81 to move upward. The top of the lower ring 81 is tightly fitted with the top of the inner wall of the tube body 3, thus achieving a sealing effect.

[0035] When the contact mechanism 8 is in use, the top of the tube body 3 has good sealing performance. It is mainly used when the external hose is connected to the tube body 3, so that the glue in the tube body 3 can only be discharged through the bottom glue outlet. At this time, the rod body 41 is difficult to rotate and adjust. In addition, the annular groove 7 is slightly larger than the limiting ring, which can achieve a slight upward movement of the height of the rod body 41.

[0036] The top of the lower ring 81 is provided with a sealing ring 9, which is a rubber ring;

[0037] Among them, the sealing ring 9 is a high-temperature resistant rubber ring. The top of the sealing ring 9 forms a tight contact with the top of the inner wall of the tube body 3 to prevent the glue from leaking or external impurities from entering. The rubber material is elastic and can adapt to the slight unevenness of the inner wall of the tube body 3, ensuring a long-term sealing effect and avoiding glue leakage that could contaminate the mechanical structure. The high-temperature resistant rubber (such as fluororubber) can adapt to heating environments (such as hot melt adhesives) and resist the chemical corrosion of the glue.

[0038] It also includes a heating element 10, which is used to heat the tube body 3. The heating element 10 includes a sleeve 101, a heat insulation cover 102, and heating tubes 103. The top of the table 1 is provided with a sleeve 101. The outer surface of the sleeve 101 is fixedly installed with a heat insulation cover 102. Four heating tubes 103 are provided inside the heat insulation cover 102.

[0039] It should be noted that a controller is installed on the top of the table 1 to control and adjust the heating element 10 and the robotic arm assembly 2. A battery is installed on the table 1 for power supply. By activating the heating element 103, the heat inside the insulation cover 102 is heated, and the heat is transferred to the sleeve 101. The robotic arm assembly 2 moves the tube 3 into the sleeve 101 to heat the tube 3, melting the solidified stubborn adhesive inside the tube 3, which can then be discharged through the bottom of the tube 3. The insulation cover 102 is set to reduce heat loss. This adhesive coating equipment is mainly used for coating low-temperature hot melt adhesive, so the temperature of the heating element 103 does not need to be too high, just enough to dissolve the low-temperature hot melt adhesive. The temperature range of the heating element 103 is 150-250°C, and a heat insulation baffle is installed on the top of the table 1 to intercept the heat.

[0040] The top of the tabletop 1 is provided with a glue discharge hole 11 that communicates with the sleeve 101.

[0041] Each of the three side propellers 42 is provided with an adhesive strip 12 on the side away from the rod 41. The adhesive surface is attached to the inner wall of the tube 3, and the adhesive strip 12 is set as a high temperature resistant strip.

[0042] The outer edges of the three side propellers 42 are provided with rubber strips 12, which are in direct contact with the inner wall of the tube body 3. All three rubber strips 12 are made of fluororubber and do not deform or age under continuous high temperature (such as hot melt adhesive conditions of 170℃).

[0043] A heat-insulating handwheel 13 is fixedly installed at the upper end of the rod 41, and a handrail is rotatably installed on the top of the heat-insulating handwheel 13.

[0044] The heat-insulated handwheel 13 is fixedly installed on the upper end of the rod 41 as a gripping component for rotation operation. It adopts a double-layer heat-insulating structure design, with the inner layer being a metal connector and the outer layer being covered with heat-insulating material.

[0045] When the adhesive is applied and the adhesive needs to be drained from the tube 3, the rod 41 is manually rotated to drive the side paddles 42 and lower paddles 43 fixed on the rod 41 to rotate synchronously. The side paddles 42 are not placed vertically on the rod 41, but at a certain angle. The three side paddles 42 are evenly distributed on the surface of the rod 41. When rotating, they are close to the inner wall of the tube 3 to scrape off the residual adhesive and prevent the adhesive from accumulating and solidifying. The adhesive in the tube 3 is discharged through the bottom outlet. Each side paddle 42 has a lower paddle 43 at the bottom, whose shape is adapted to the bottom of the inner wall of the tube 3. When rotating, it thoroughly scrapes off the adhesive deposited at the bottom of the tube to avoid blockage. The heating pipe 103 is activated to heat the insulation cover 102. The heat is transferred to the sleeve 101. The robotic arm 2 is used to move the tube 3 into the sleeve 101 to heat the tube 3, melting the solidified stubborn adhesive inside the tube 3, so that it can be discharged through the bottom of the tube 3.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
