Description

Technical Field

[0001] The utility model relates to the technical field of foam board processing, in particular to a turnover loading device for cutting large foam boards. Background Technique

[0002] The foam board, usually referring to the polystyrene foam board, is a material with good heat preservation, heat insulation and buffering properties. It has a relatively light weight and good heat preservation performance and is often used for building insulation. The application of the foam board is very extensive. In the construction field, it can be used as an external wall insulation material, a roof insulation layer, etc. In the logistics packaging field, it can be used to wrap fragile items to reduce damage during transportation.

[0003] Chinese Patent Publication No. CN 219075822 U discloses a foam board cutting auxiliary turnover device, which includes a material discharging rod. A plurality of material discharging rods are provided, and a support rod is fixedly connected to the plurality of material discharging rods. The support rod is perpendicular to the material discharging rod; a transfer table, the support rod is rotatably connected to the transfer table, the transfer table is fixedly connected with a turnover gear, the support rod is rotatably connected with a turnover rod, and the turnover rod is engaged with the turnover gear; a material discharging roller, the material discharging roller is rotatably connected to the support rod, the support rod is rotatably connected with a transfer gear, the transfer gear is fixedly connected to the material discharging roller, and a transfer rod is rotatably connected to the support rod at a position corresponding to the transfer gear, and the transfer rod is engaged with the transfer gear; a turnover motor, the turnover motor is fixedly connected to the material discharging rod, the output shaft of the turnover motor is connected with a control rod, the turnover motor can always drive the turnover rod to rotate, and the control rod can respectively control the transfer rod or the turnover rod to rotate;

[0004] For the above-mentioned foam board cutting auxiliary turnover device, the turnover rod and the material discharging rod cooperate to clamp the foam board, and then the turnover motor drives the turnover rod and the material discharging rod to rotate, so as to realize the turnover of the foam board. However, the above-mentioned turnover device only clamps one end of the foam board. When turning and transporting the foam board, only one end of the foam board is stressed, and the foam board is very light on the ground. When it is turned over, the air resistance it receives is very large, especially for large foam boards, the wind resistance it receives is greater; because the direction of the wind resistance is opposite to the movement direction of the turnover rod and the material discharging rod, the foam board will break due to the action of different directions. The faster the movement speed of the turnover rod and the material discharging rod, the greater the force received by the foam board, and the greater the probability of its breaking. Reducing the movement speed of the turnover rod and the material discharging rod will greatly reduce the efficiency of the foam board cutting work. Content of the Utility Model
