Description

Technical Field

[0001] The invention relates to the technical field of automatic feeding equipment, in particular to a tray-type feeding machine. Background Art

[0002] In traditional powder processing industries such as food, medicine, chemicals, pesticides, feed, ceramics, glass, cement, fuel, etc., raw materials are generally transported to the production line through a feeding device for processing. Traditional processing generally involves screening and feeding materials through a vibrating plate.

[0003] With the continuous development and progress of society, the increasing development of automated production, and the large-scale use of industrial robots, the vibration plate can only be used to feed one type of material. Changing the material requires re-customizing the corresponding vibration plate, which has a long production cycle and a small scope of application. This has invisibly increased a lot of production costs, resulting in it no longer meeting the processing needs of the increasingly developed automated production.

[0004] Therefore, in view of the above defects, it is necessary to research and develop a feeding mechanism that can be suitable for a variety of different materials to solve the problem of single material adaptation of the traditional vibration plate feeding structure. Summary of the invention

[0005] The purpose of the present invention is to provide a tray-type loader to solve the problem that the traditional vibration tray loading structure can only be applied to a single material, and different materials need to be customized with different vibration trays, resulting in a long equipment production cycle, a small scope of application and high production costs.

[0006] In order to achieve the above purpose, the present invention provides a tray loading machine, the specific implementation scheme is as follows:

[0007] A tray-type loader comprises a loader body, a loading platform and a hopper are provided at the bottom of the loader body, a plurality of trays are provided in the hopper, the trays are stacked in the hopper, a tray-changing clamp is provided at the top of the hopper, the tray-changing clamp is clamped at two ends of the tray, and a driving device is provided at the end of the tray-changing clamp, and the bottom of the driving device is movably connected to the loader body; when the tray-changing clamp clamps the tray, the driving device drives the tray-changing clamp to rise and fall and move on the loader body to place the tray on the loading platform.

[0008] In traditional powder processing industries such as food, medicine, chemicals, pesticides, feed, ceramics, glass, cement, and fuel, most of the materials are fed by a vibration plate structure, so that the materials are transported to the production line for production and processing. However, since the traditional vibration plate structure can only be applied to the feeding of one type of material, a customized vibration plate is required for each different type of material. As a result, the feeding structure cannot be adapted to the feeding of different materials, has a small scope of application, and has a long manufacturing cycle for replacing the vibration plate, resulting in high manufacturing costs.

[0009] Compared with the prior art, the present invention provides a tray-type loader, which is stacked in the hopper by arranging a hopper and a loading platform on the loader body, and takes the tray out of the hopper by using a tray-changing clamp, and drives the tray-changing clamp to perform lifting and displacement activities on the loader body through a driving device on the tray-changing clamp, and clamps the tray on the loading platform for an external mechanical arm to clamp the material in the tray, so that the loader can be adapted to the loading of a variety of different materials, thereby improving the application range of the loader. It effectively solves the problem that the traditional vibration plate loading structure can only be applied to a single material, and different materials need to be customized with different vibration plates, resulting in a long equipment production cycle, a small application range, and high production costs.

[0010] As a further improvement of the present invention, the driving device includes a connecting part, a lifting mechanism and a moving mechanism, the connecting part is respectively connected to the disc changing clamp and the lifting mechanism, the bottom of the lifting mechanism is connected to the moving mechanism, and the moving mechanism is connected to the loader body.

[0014] As a further improvement of the present invention, a third rodless cylinder is provided at the bottom of the loading machine body, and both ends of the third rodless cylinder are respectively located at the bottom of the loading platform and the silo, and the third rodless cylinder is fixedly connected to the loading platform; when the material in the tray on the loading platform is loaded, the third rodless cylinder operates to transport the tray into the silo.

[0015] Furthermore, a hook is provided at the end of the loading platform. When the material tray is placed on the loading platform, the hook abuts against the side of the material tray, so that the material tray is transported into the silo following the position of the loading platform.

[0016] As a further improvement of the present invention, lifting cylinders are provided on both sides of the silo, lifting claws are connected to the lifting cylinders, lifting troughs are provided on both sides of the silo for lifting the lifting claws, and the lifting claws pass through the lifting troughs to clamp both sides of the material tray.

[0017] Furthermore, two sides of the silo are provided with clamping blocks, the clamping blocks are located between the lifting clamps and the limit blocks, and two sides of the silo are provided with air avoidance grooves, both ends of the air avoidance grooves are provided with rotating shafts, and both ends of the clamping blocks are inserted into the rotating shafts and are rotatably connected to the rotating shafts.

[0018] As a further improvement of the present invention, a material rack is provided in the material tray, and a plurality of material troughs for accommodating materials are provided in the material rack.

[0019] Based on the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0024] 5. By arranging clamping blocks on both sides of the silo, it is used to provide support force for the material tray in the silo, so as to avoid the situation that after the material tray is lifted from the bottom of the silo by the lifting claws, the material tray loses the support force and is adjusted back to the bottom of the silo when the lifting claws are removed.

[0025] 6. By arranging a material rack on the material tray and arranging multiple material troughs on the material rack, the material rack can be replaced according to the type of material to be fed without replacing the material tray, which reduces the production cost and production cycle of the feeder and increases the application scope of the feeder.
