Description

Technical Field

[0001] This utility model relates to the field of adhesive processing technology, and in particular to a stirring device for adhesives. Background Technology

[0002] Alcohol-soluble polyurethane adhesives are environmentally friendly polyurethane adhesives that use alcohols such as ethanol and isopropanol as solvents. Neither the main component nor the curing agent contains free isocyanate groups (-NCO), making them non-toxic, low in VOC emissions, and compliant with green packaging and environmental regulations. Their curing mechanism involves the reaction of hydroxyl groups (-OH) with epoxy groups, requiring a catalyst (such as DMP-30) to promote the cross-linking reaction at 70-100℃. Curing can also be completed at room temperature. A crucial step in the production process of alcohol-soluble polyurethane adhesives is the mixing and stirring of various raw materials.

[0003] Existing adhesive mixing devices typically use a fixed mixing drum, which can lead to incomplete mixing in certain areas due to dead zones during mixing. High-viscosity adhesives, in particular, tend to adhere to the drum wall, forming a residue layer. This not only affects product quality but also increases the difficulty of subsequent cleaning, making it difficult to meet the demands of continuous production for multi-directional mixing and rapid cleaning. Especially when handling adhesives prone to sedimentation or requiring thorough agitation, incomplete mixing and inadequate cleaning are common problems. Therefore, this application provides an adhesive mixing device to address these needs. Utility Model Content

[0025] like Figure 1 , Figure 2 and Figure 3As shown, an embodiment of this utility model provides a mixing device for adhesives, including a support frame 1. Support rods 2 are symmetrically and obliquely fixed on both sides of the support frame 1. Leveling knobs 3 are installed at the four corners of the bottom of the support frame 1. The support frame 1 and the leveling knobs 3 are threaded together. By setting the leveling knobs 3, it can be ensured that the device will not tilt or shake during operation, thus ensuring the overall stability of the device. A mixing cylinder 4 is rotatably mounted on the support frame 1. A mixing chamber 5 is opened inside the mixing cylinder 4.

[0026] The top of the aforementioned mixing drum 4 is covered with a top seat 10. A handle 101 is installed on the top of the top seat 10. Two handles 101 are symmetrically arranged. A rotating rod 6 is rotatably installed at the bottom of the top seat 10. A stirring rod 7 is fixed at the outer edge of the rotating rod 6. A fixing hole is opened at the center of the stirring rod 7. A fixing bolt that cooperates with the rotating rod 6 is installed at the fixing hole of the stirring rod 7.

[0027] The transmission structure of the worm gear 61 and worm 81 has a self-locking characteristic, which can reliably keep the stirring rod 7 stationary when the stirring motor 8 stops running, avoiding accidental rotation due to inertia, and ensuring that the adhesive is thoroughly stirred during operation.

[0028] like Figure 1 , Figure 2 and Figure 4 As shown, a fixing assembly 11 for fixing an auxiliary top seat 10 is installed at the top of the outer side of the mixing drum 4. The fixing assembly 11 includes a hinge seat 12 fixed on the mixing drum 4. A snap block 13 is hingedly installed on the hinge seat 12. A top pressure screw 14 is threaded on the snap block 13. The bottom of the top pressure screw 14 presses against the top of the top seat 10.

[0029] The fixing component 11 is designed with a combination of C-shaped snap-fit ​​block 13 and top pressure screw 14. The top pressure screw 14 applies uniform top pressure to the top seat 10 to ensure a firm seal between the top seat 10 and the mixing drum 4 during the mixing process, preventing adhesive leakage and external contamination. In actual operation, a sealing gasket can be installed at the bottom of the top seat 10 for sealing.

[0030] like Figure 1 and Figure 5As shown, the support frame 1 has an adjustment cavity inside, and an adjustment component 15 for assisting the rotation of the stirring drum 4 is installed in the adjustment cavity. The adjustment component 15 includes sprockets 16 symmetrically arranged in the adjustment cavity. One sprocket 16 is fixed to the side of the stirring drum 4 by a connecting rod, and a rotating disk 18 is fixed to the outer side of the other sprocket 16. The two sprockets 16 are connected by a chain 17, and a fixing rod is fixed to the outer side of the rotating disk 18.

[0031] The adjustment component 15 in the adjustment cavity of the support frame 1 is connected to two sprockets 16 via a chain 17. One sprocket 16 is fixed to the side of the mixing drum 4, and the other sprocket 16 is connected to the rotating disk 18. When the rotating disk 18 rotates, the mixing drum 4 is driven to rotate synchronously via the chain 17, thereby realizing multi-directional adjustment of the stirring angle. The stirring angle of the mixing drum 4 can be adjusted in multiple directions. It can also achieve overall shaking and stirring of the colloid by shaking during stirring. At the same time, it can facilitate cleaning of the inside of the mixing drum 4 in subsequent work and afterward.

The top seat 10 is fixed by the hinge seat 12 of the fixing component 11 and the snap block 13. The top seat 10 is pressed and fixed by the top screw 14 and the rotating handle 141 to ensure the sealing between the top seat 10 and the mixing cylinder 4 during the mixing process.

[0035] The stirring motor 8 drives the rotating rod 6 to rotate at the bottom of the top seat 10 through the meshing transmission of the worm gear 81 and the worm wheel 61, thereby driving the stirring rod 7 to efficiently stir the adhesive in the stirring chamber 5. The adjusting component 15 in the adjusting chamber of the support frame 1 is connected to two sprockets 16 through the chain 17. One sprocket 16 is fixed to the side of the stirring drum 4, and the other sprocket 16 is connected to the rotating disk 18. When the rotating disk 18 rotates, it drives the stirring drum 4 to rotate synchronously through the chain 17, realizing multi-directional adjustment of the stirring angle. The positioning bolts 191 on the positioning disk 19 cooperate with the positioning holes 192 on the outside of the support frame 1. The circular array of positioning holes 192 provides multiple angle fixing options to ensure that the stirring drum 4 is stably locked after rotating to the required angle.

[0036] The leveling knob 3 at the bottom of the support frame 1 adjusts the height of the four corners via threads, which, together with the inclined support rods 2 on both sides, ensures that the equipment remains level and stable under different ground conditions.
