Description

Technical Field

[0001] This utility model relates to the technical field of chain plate feeders, and in particular to a chain plate feeder with adjustable tension. Background Technology

[0002] Chain plate material feeders are used in the brick and tile industry for uniform feeding of raw materials before and after aging. Materials include clay, fly ash, loose shale, coal gangue (block size <150 mm, a small amount 200 mm), etc.

[0003] Chinese Patent Publication No. CN 208994730 U discloses a stabilizing device for a chain plate material feeder, including a feeder body. A support plate is fixedly connected to the right side wall of the feeder body, and a support seat is fixedly connected to the left side wall of the feeder body. A base plate is fixedly connected to the bottom end of the support plate and the support seat. In this stabilizing device, material enters the collection box from the feed hopper. At this moment, the material presses down on the baffle plates on both sides. Under the action of springs, the pin on one side of the baffle plate slides in an arc-shaped groove, allowing the material to fall stably onto the feeding plate. The material is then guided onto the feeder body through the discharge hopper, improving the stability of the material during feeding. Reinforcing ribs enhance the stability of the connection between the collection box and the support seat. The feeder body is fixedly connected between the support plate and the support seat, and with the support legs at the bottom end of the base plate, the stability of the device during feeding is greatly improved, which is conducive to its promotion and widespread adoption.

[0004] The existing technical solutions mentioned above have the following shortcomings: While they can achieve stable feeding during use, their single-point feeding structure results in the middle part of the chain plate feeder being subjected to more gravity, leading to uneven overall force distribution and room for optimization. Therefore, it is necessary to design a chain plate feeder with adjustable tension to solve the aforementioned problems. Utility Model Content
