Description

Technical Field

[0001] This utility model relates to a feeding and conveying device for a stretching device, and more particularly to a sheet material conveying device. Background Technology

[0002] In the manufacturing process of wheel spokes, a stretching device is needed to stretch and shape the sheet material.

[0003] Currently, pneumatic suction cups are often used for feeding during stretching. When the suction cup picks up the material, the lifting range of the stretching station is fixed. However, as the stacked sheets are picked up, the lifting range gradually increases. Existing technology often adapts to this change by setting the suction cup for sheet feeding to be supported by a spring. However, in actual production, the overall thickness of the stacked sheets is relatively large. If this structure is used to adapt, the spring would need to be very long, and the pressure applied by the spring would gradually decrease during the adaptation process, which would have a certain impact on the picking. Utility Model Content

The rectangle is a square at its smallest size, with the side length of the square being the same as the diameter of the sheet material. The feeding mechanism 20 and the unloading mechanism 50 are set up separately to prevent them from interfering with each other. A conveyor belt connects the two, and after feeding, the material is stopped by a stop post 301 and then positioned by the positioning mechanism 40. This ensures accurate unloading by the unloading mechanism 50, thus guaranteeing the positional accuracy for subsequent stretching.

When the material is fed to the lifting device, the first feeding suction cup 505 moves above the positioning platform 401 and descends to pick up the sheet material on the positioning platform 401. During this process, the remaining feeding suction cups 505 pick up the semi-finished products at each station of the lifting device, and then move down one station. The semi-finished products picked up by the last feeding suction cup 505 are collected for subsequent processes, and so on.

In this application, the guide rail 202 consists of two guide rail columns, and the translation frame 203 is slidably sleeved on the guide rail columns 202.

[0019] Preferably, the unloading mechanism 50 includes an unloading rack 502 that can be vertically lifted and horizontally moved, and the unloading rack 502 is equipped with several second pneumatic suction cups with the same lifting range. This solution uses multiple unloading racks 502 to pick up the material from the previous station and place it into the next station, with the first end being the sheet material at the positioning table 401.

[0020] Preferably, the feeding mechanism 50 is used to feed the stretching device, which has multiple equidistant stretching stations. The number of second pneumatic suction cups is one more than the number of stretching stations and they are naturally located in the gap between adjacent stretching stations.
