Description

A feeding mechanism of a trademark automatic hemming machine

Technical Field

The utility model discloses a feeding mechanism of an automatic trademark hemming machine and belongs to the technical field of trademark hemming machines.

Background technique

The textile industry needs to mark fabrics during the fabric processing process. For example, carpets, bath mats, clothing and other products need to be marked with text and pictures, such as production date, expiration date and product number, etc., and the extended part of the product needs to be edged with hemming tape, and the trademark needs to be sewn into the hemming tape.

At present, the existing automatic trademark hemming machines generally use a conveyor belt to transfer the trademark to a workbench, and then a robotic arm grabs the trademark and takes it to a sewing machine for hemming. However, after the trademark is transferred to the workbench, it is easy for it to be scattered or stacked, resulting in the inability of the robotic arm to grab it or the grabbing is unstable, which in turn leads to defective products and low processing efficiency during the trademark hemming process.

Therefore, a new solution needs to be proposed to solve this problem.

The material moving device includes a support platform 7, a material moving arm 8 and a vacuum suction cup 9. The support platform 7 is arranged on the workbench 1, and the material moving arm 8 includes a connecting end and an adsorption end. The connecting end of the material moving arm 8 is connected to the support platform 7 and the adsorption end extends to the upper side of the material rack. The vacuum suction cup 9 is arranged at the adsorption end of the material moving arm 8. The material moving arm 8 can rotate with the connecting end as the center. The workbench 1 is provided with a vacuum generator connected to the vacuum suction cup 9. When the trademark needs to be hemmed, the adsorption end of the material moving arm 8 rotates to the upper side of the material rack, and the vacuum generator is started to make the vacuum suction cup 9 adsorb the trademark on the upper end of the material rack, and then the adsorption end of the material moving arm 8 rotates to the upper side of the workbench 1, and the vacuum suction cup 9 puts down the trademark to complete the loading of the trademark.

The material holding rack is composed of a rectangular bottom plate 10 and three U-shaped support frames 11. One end of the bottom plate 10 is connected to the workbench 1. The three U-shaped support frames 11 are arranged on the upper sides of the three ends of the bottom plate 10 that are not in contact with the workbench 1. The three U-shaped support frames 11 and the side walls of the workbench 1 form a material holding cavity. The lifting rod 5 passes through the U-shaped support frame 11 and extends into the material holding cavity. The lifting block 6 is arranged in the material holding cavity.
