Description

Technical Field

[0001] The utility model relates to the field of material conveying devices, in particular to a powder feeding device used for resin production. Background Art

[0002] Resin is an organic polymer that softens or melts when heated and has a tendency to flow under external force. At room temperature, resin is usually solid or semi-solid, and sometimes liquid. In a broad sense, resin refers to any polymer compound that can be used as a raw material for plastic products. It can be divided into two categories: natural resin and synthetic resin. Resin is widely used in the manufacture of plastics, coatings, adhesives, insulating materials, etc.

[0003] The production of resin requires the use of a variety of raw materials, including monomers, solvents, catalysts, stabilizers, etc. Monomers are the main raw materials of resins, generally including ethylene, propylene, styrene, methyl methacrylate, etc. In the raw material preparation stage, the raw materials need to be strictly screened and stored to ensure that the quality and purity of the raw materials meet the production requirements. Therefore, a powder feeding device for resin production is needed to solve the impurity filtering problem of the powder feeding device for resin production. Utility Model Content

[0004] The purpose of the invention of the utility model is to provide a powder feeding device for resin production to solve the impurity filtering problem of the powder feeding device for resin production, by setting a screen to screen out unqualified resin or impurities, and then using a magnetic rod to remove the magnetic material in the resin, and finally controlling the resin feeding speed through a feeding baffle, so that the magnetic material in the resin can be fully removed by the magnetic rod, so as to solve the impurity filtering problem of the powder feeding device for resin production.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a powder feeding device for resin production, including a feeding box, a screen is provided in the feeding box, the screen is connected to an external first driving member, the first driving member drives the screen to reciprocate horizontally, a plurality of magnetic rods for removing magnetic materials are provided inside the feeding box discharge port, the magnetic rods are connected to an external second driving member, the second driving member drives the magnetic rods to perform circular motion, a plurality of unloading baffles are also provided inside the feeding box discharge port, the unloading baffles are connected to an external third driving member, and the third driving member drives the unloading baffles to perform circular motion.

[0006] When resin powder is put into production, the resin is put into the feeding port of the feeding box, and the reciprocating motion of the screen screens out unqualified resin or impurities. The qualified resin falls from the screen and passes through the magnetic rod, which removes the magnetic substance in the resin. The magnetic rod also plays a certain stirring role to prevent the resin powder from clogging the discharge pipe of the feeding box. Then the discharge baffle will block the discharge of the resin and control the discharge speed of the resin according to the set rotation speed to avoid the resin passing over the magnetic rod due to too fast a discharge speed, resulting in insufficient removal of the magnetic substance. At the same time, the controllable discharge speed is conducive to optimizing product quality and enhancing production flexibility.

[0007] As a preferred solution of the utility model, a support frame is provided between the feeding box and the first driving member, the first driving member is connected with a rotating disk, a transmission rod is provided between the rotating disk and the screen, one end of the transmission rod is connected to the rotating disk by a rotating shaft, and the other end is also connected to the screen by a rotating shaft, a guide frame and a guide groove supporting the reciprocating motion of the screen are provided on the wall of the feeding box, the screen is in direct contact with the guide frame, and at least two layers of sealing rings are provided between the screen and the guide groove.

[0008] As a preferred solution of the utility model, a connecting seat is provided between the magnetic rod and the second driving member, a powder cutting cone is provided on the magnetic rod, and a connecting seat is also provided between the unloading baffle and the third driving member. The connecting seat plays the role of an intermediate connecting support, and multiple magnetic rods are installed on the connecting seat.

The powder cutting cone on the magnetic rod can cut the powder and reduce the rotational resistance of the magnetic rod when it makes a circular motion.

[0009] As a preferred solution of the utility model, a feeding port is provided at the top of the feeding box, the neck of the feeding port is non-linear and bent to one side, and the feeding port is provided with multiple dust suppression plates. The non-linear feeding port design that is bent to one side slows down the impact speed of the powder falling to the screen, reduces the generation of dust raised upward, and the dust suppression plate can effectively block the channel for the powder to be raised upward, thereby reducing the amount of powder raised by the feeding device in many aspects.

[0012] As a preferred solution of the utility model, a soft pad is provided between the support frame and the first driving member. The provision of the soft pad can reduce the noise and vibration of the first driving member.

[0013] As a preferred solution of the present utility model, the first driving member, the second driving member and the third driving member are all motors, which are suitable for various driving requirements and have high reliability.

[0017] 3. The connecting seat serves as an intermediate connecting support. Multiple magnetic rods are installed on the connecting seat. The motor drives the connecting seat to rotate, and the connecting seat drives the magnetic rods to make circular motion. In addition to removing the magnetic substance in the resin powder, the magnetic rods can prevent the powder from piling up and play a certain role in dispersion and stirring. The powder cutting cone on the magnetic rod can cut the powder and reduce the rotational resistance of the magnetic rod when it makes circular motion.

[0018] 4. The non-linear feeding port design that is bent to one side slows down the impact speed of the powder falling to the screen and reduces the generation of dust raised upward. The dust suppression plate can effectively block the channel for the powder to be raised upward, thus reducing the amount of powder raised by the feeding device in many ways.

[0019] 5. The hose can be used to compensate for the displacement and stress generated by the feeding device to prevent damage to the equipment or pipeline. At the same time, when the pipeline is blocked, the hose can be easily pushed and squeezed to prevent the pipeline from being blocked.
