Description

Technical Field

[0001] This application relates to the field of vibrating screen equipment technology, specifically to a feeding device for a screening machine. Background Technology

[0002] Sucrose, also known as β-D-fructofuranosyl-α-D-glucopyranoside, is a colorless or white crystalline loose powder. As an industrial, edible, and medicinal raw material, sucrose has been used for hundreds of years. It is not only a flavoring agent that brings people a pleasant and delicious taste, but also an essential part of life, one of the three major sources of nutrition for the human body. After consumption, sucrose is digested and broken down into monosaccharides (glucose and fructose), which are absorbed and utilized by the body to generate energy, build the body, maintain physiological functions, restore physical strength, and relieve fatigue. Sucrose is widely used not only in the food and chemical industries, but also plays a very important role in the pharmaceutical industry as a pharmaceutical excipient. Sucrose is widely used in the formulation processes of tablets, syrups, chewable tablets, lozenges, and oral liquid preparations, serving as a sweetener, diluent, excipient, binder, and humectant in pharmaceuticals.

[0003] Currently, the screening of pharmaceutical sucrose involves manual labor in sterile clothing pouring the sucrose into a screening machine. Because this type of sucrose is specially made in spherical form, it cannot be struck by external force, and the feeding process cannot be done by stirring. However, the method of manually opening the bagged raw material and directly pouring it into the screening machine is inefficient, cannot guarantee uniform screening, and has low production capacity. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a feeding device for a screening machine, which can uniformly feed sucrose onto the screening machine;

[0005] The technical objective of this utility model is achieved through the following technical means:

[0006] A feeding device for a screening machine includes a receiving hopper and a conveying mechanism. The receiving hopper is installed above the feeding end of the conveying mechanism, and the output end of the conveying mechanism is connected to the feeding device. The feeding device includes a feed inlet for the output end of the conveying mechanism to enter the feeding device, and a guiding device is provided inside it. The guiding device includes a receiving plate, a guiding plate, and a discharge plate. The receiving plate is inclined downwards, and one end is hinged to the inside of the feeding device near the feed inlet. The guiding plate is located below the receiving plate, and one end of the guiding plate is fixedly installed on the inner wall of the feeding device, while the other end is inclined downwards and connected to the bottom plate of the feeding device. The guiding plate is provided with a plurality of guiding holes. A guiding groove is provided at the lower end of the guiding plate. The discharge plate is connected to the lower end of the guiding groove.

[0007] Furthermore, the conveying mechanism includes a front housing and a rear housing, and a matching conveyor belt is installed inside the front housing and the rear housing; a drive motor for driving the conveyor belt to roll is fixedly installed outside the front housing.

[0008] Furthermore, the material guide trough is provided in several sections, all of which are inclined downwards; the discharge port is located at the outlet end of the material guide trough and is inclined downwards to connect with the screening machine, with an inclination angle of 10°-15°.

[0009] Furthermore, a rotating device is also provided outside the feeding device. The rotating device is movably connected to the bottom of the receiving plate. The receiving plate is rotatably installed inside the feeding device with its end connected to the feeding device as an axis. When feeding, the feeding plate is rotated to a suitable angle, which can quickly and effectively feed the feeding plate. At the same time, the feeding plate can also withstand the impact of feeding.

[0010] Furthermore, a vibrator is also installed at the bottom of the feeding device, which is located near the connection point between the guide plate and the guide chute. When the guide chute is blocked, the vibrator can be activated to clear the blockage.

[0011] Furthermore, a support frame is fixedly installed below the feeding device.

[0012] The feeding device of the screening machine of this utility model allows the finished pharmaceutical sucrose to be fed directly into the feeding device by the conveying mechanism through the receiving hopper for screening. A guide trough is set in the feeding device, and the guide channel in the guide trough can evenly unload the material onto the screening machine, which improves efficiency and ensures uniform screening.
