Description

Technical Field

[0001] The present application relates to the field of feeding devices, and in particular to a feeding screw. Background Art

[0002] Since solid powder is non-flowing, it is easy to accumulate at the bottom of the premix tank under the action of gravity. In the production process of solid powder products, it is difficult to realize discharging and packaging without relying on external force. The material is often taken out through the opening at the bottom of the premix tank. If the discharging opening is small, no material will be discharged. If the discharging opening is large, it is difficult to control the powder discharging speed and amount. If the material is taken out manually, the powder will frequently contact the working environment, increasing the risk of product quality and safety. In addition, the manual material taking process is discontinuous, which greatly reduces production efficiency. For this reason, it is urgent to create a linkage solid powder conveying equipment to drive the solid powder to flow out from the discharging port. Summary of the invention

[0003] The purpose of the embodiments of the present application is to provide a feeding screw which can solve the technical problem of discontinuous manual feeding.

[0004] An embodiment of the present application provides a feeding screw, including a sleeve, a motor, a transmission shaft, and a spiral blade. A feed pipe is provided on one side of the upper end of the sleeve, and a discharge pipe is provided on the other side of the lower end of the sleeve. The transmission shaft can be rotatably installed inside the sleeve, and the spiral blade is installed on the transmission shaft. The motor is installed at one end of the sleeve and passes through the sleeve to be connected to the transmission shaft.

[0005] Preferably, a seat frame is provided at the upper end of the sleeve, and at least two of the seat frames are provided.

[0006] Preferably, a mounting frame is provided inside the sleeve, and the transmission shaft can be rotatably mounted on the mounting frame.

[0007] Preferably, the feed pipe and the discharge pipe are both provided with clamps.

[0008] Preferably, a feed hopper is provided at the upper end of the feed pipe.

[0009] Preferably, one end of the transmission shaft close to the motor is a tenon, and the output shaft of the motor is a mortise, and the tenon and the mortise are used in conjunction with each other.

[0010] Preferably, the sleeve, motor, transmission shaft and spiral blades are all made of stainless steel.

[0011] Beneficial effects of the utility model:

[0012] The utility model provides a feeding screw, including a sleeve, a motor, a transmission shaft, and spiral blades. A feed pipe is provided on one side of the upper end of the sleeve, and a discharge pipe is provided on the other side of the lower end of the sleeve. The transmission shaft can be rotatably installed inside the sleeve, and the spiral blades are installed on the transmission shaft.
