Description

Technical Field

[0001] The utility model relates to the field of footwear production, in particular to a rubber mixing and bonding device for sandal production. Background Art

[0002] Sandals are an open type of footwear, usually worn in the summer, with ventilation and breathability, which can bring a cool feeling to the feet. In the process of sandal production, glue bonding is a common shoemaking process, which is mainly used to glue the upper and the sole together. First, select the appropriate glue, apply the selected glue evenly on the sole to be bonded, then put the upper together to bond, fit the two parts coated with glue tightly, make sure there are no bubbles or gaps, and then fix them with appropriate pressure for a period of time to allow the glue to fully penetrate and solidify, and finally let the bonded parts dry naturally or use drying equipment to accelerate the drying process until the glue is completely solidified to form a strong bond.

[0003] The rubber mixing and bonding device used in the above process has a patent number of CN220681675U and is named as an environmentally friendly rubber mixing and bonding device for sandal production. Although suction is generated inside the glue return box, the excess glue inside the glue discharge head is adsorbed to the inside of the glue return box through the glue return tube, thereby effectively avoiding the glue from dripping inside the glue discharge head, thereby avoiding glue waste and preventing the glue from contaminating the inside of the workbench and the sandals, thereby ensuring the cleanliness of the equipment and sandals.

[0004] However, the glue head can only be moved and adjusted in the vertical direction, and cannot be adjusted in the horizontal direction as needed, so the practicality is low, and there is no pressure bonding structure for the sole and upper, resulting in insufficient bonding effect. After bonding, there is no structure to accelerate the drying and curing of the glue, so it can only dry naturally, which wastes time and reduces efficiency. Utility Model Content
