Description

Technical Field

[0001] The invention belongs to the field of feeding devices, and in particular relates to a feeding device based on hot melt adhesive bonding. Background Art

[0002] In the existing production of inner plugs and gaskets, traditional equipment for specialized materials like aluminum mesh faces numerous limitations. Because aluminum mesh cannot be attracted by magnets or gripped by vacuum machines, traditional equipment often relies on manual placement, resulting in a low level of automation and inefficient production. Furthermore, manual operation can easily lead to mesh positioning errors, compromising the accuracy of the inner plugging and gasketing process, leading to inconsistent product quality and a high defective rate.

[0003] Furthermore, traditional equipment lacks structural adaptability. Frequent adjustments to accommodate different stoppers and bottle sizes are required, which not only complicates operations but also disrupts the production process, reducing continuity. Furthermore, the equipment's components lack synergy, resulting in poor integration between conveying, gripping, and laminating processes. This further hinders improvements in production efficiency and product quality, making it difficult to meet the demands of modern mass production. Summary of the Invention

[0037] Working principle:

[0038] Conveying of inner plugs and bottles: The chain conveyor line is installed inside the frame. After starting, it drives the inner plugs and bottles to move along the conveying path, passing through the positioning, padding and other processing stations in turn to achieve continuous conveying.

[0039] Aluminum mesh supply: In the stacking mesh turntable assembly, the right-angle hollow reduction motor drives the cam divider to rotate, driving the stacking mesh turntable to rotate, and the stacked aluminum mesh is transported in an orderly manner to the grasping area of ​​the grasping robot assembly, providing stable material supply for subsequent grasping.

[0040] Grasping and processing the aluminum mesh: The PPU robot of the mesh grabbing robot assembly moves precisely on the fixed frame. When the mesh stacking turntable sends the aluminum mesh to the grabbing position, the first power switch detects the signal and triggers the action: the heating component heats the hot melt adhesive at the bottom, and the PPU robot drives the heating component downward through the finger fixing plate, using the hot melt adhesive to stick to the aluminum mesh; then, the PPU robot moves to the top of the inner plug.

[0041] Aluminum mesh fits the inner plug: When the inner plug reaches the padding position along the chain conveyor line, the second cylinder of the bottle blocking assembly drives the bottle blocking plate to extend, blocking the bottle from moving forward to position it; the second power switch of the electric eye assembly detects the position of the inner plug and feeds back a signal, and the first cylinder of the net grabbing robot assembly pushes the heating component downward, pressing the aluminum mesh onto the inner plug with hot melt adhesive to complete the padding.

[0042] Conveying and guardrail assistance: After the padding is completed, the bottle baffle is retracted and the chain conveyor line sends the product to the next link; the guardrail bracket assembly limits the position of the bottle through the U-shaped bracket and the internal tooth connecting rod to prevent deviation during transportation and ensure processing stability.

[0043] Each component is linked through signals such as electric eyes and power switches to realize the fully automatic process of "aluminum mesh supply - grabbing - heating and gluing - positioning and pressing - transportation", and efficiently complete the internal plugging and padding operations.

[0044] The above embodiments are only used to illustrate the present invention, and are not intended to limit the present invention. Ordinary technicians in the relevant technical field may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions also fall within the scope of the present invention. The scope of patent protection of the present invention should be defined by the claims.
