Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of plastic product manufacturing equipment, specifically relating to a feeding device for plastic product manufacturing. Background Technology
[0002] In the production of plastic products, plastic raw materials (such as plastic granules and powders) need to be conveyed to the feed inlets of production equipment such as extruders and injection molding machines. This process usually relies on a feeding device. Currently, most common feeding devices for plastic product production on the market adopt a single screw conveyor or negative pressure suction structure. In actual use, the following problems exist: Existing feeding devices are generally negative pressure suction, but since the raw materials are for plastic product production, if the raw material has a high moisture content, the raw material is prone to blockage inside the channel, causing feeding interruption, requiring machine shutdown for cleaning, wasting time and causing trouble. In addition, during the feeding process, plastic raw materials are also prone to adhering to the inner wall of the suction pipe. However, the suction pipe is generally welded to the feeding device, which makes cleaning more troublesome. Although the impact is not significant, it will cause the cavity to narrow, affecting the feeding speed. The outlet discharge port of existing feeding devices is generally open. When these plastic granules are discharged, due to inertia, the direction of discharge is not certain, and the discharge speed is also very fast, which can easily scatter outside, causing waste of raw materials and having a certain impact on the hygiene of the production environment. Utility Model Content
[0003] To achieve the above objectives, this utility model provides the following technical solution: a feeding device for plastic product manufacturing, comprising a device frame and a feeding conical hopper. The feeding conical hopper is welded to the top of the device frame, and a feeding motor is fixed to the bottom of the device frame. A feeding auger is installed inside the feeding conical hopper, and the feeding motor is connected to the feeding auger via a pulley assembly. A stirring motor is fixed to the side of the feeding conical hopper, and a stirring roller is also installed inside the feeding conical hopper. The stirring roller is connected to the stirring motor. The device also includes a feeding inclined pipe, which is divided into upper and lower sections. A feeding pipe splicing flange is installed at the connection between the upper and lower sections of the feeding inclined pipe, and the two sections are connected and fixed through the feeding pipe splicing flange. The lower section of the feeding inclined pipe is fixed to the feeding conical hopper, and the feeding auger is installed inside the feeding inclined pipe. A discharge vertical pipe is installed at the top of the feeding inclined pipe, and the discharge vertical pipe and the feeding inclined pipe are welded and fixed together.

[0005] As a preferred technical solution of the feeding device for plastic product production according to this utility model, the surface of the stirring roller is provided with multiple stirring rods at equal intervals. The lengths of the stirring rods are different, and the lengths of the stirring rods are adapted to the internal space of the feeding cone hopper.
[0006] As a preferred technical solution of the feeding device for plastic product production according to this utility model, the feeding pipe splicing flange is provided with multiple easy-to-remove screw holes, which are arranged in a circular array and fixed by external bolts.
[0007] As a preferred technical solution of the feeding device for plastic product production according to this utility model, the feeding motor and the stirring motor are electrically connected to an external power source. The feeding motor 2 is a Y-series three-phase asynchronous gear reduction motor, specifically model Y100L1-4, and the stirring motor 3 is a Y90S-4 type 1.1kW motor.

[0009] As a preferred technical solution of the feeding device for plastic product manufacturing according to this utility model, the bottom of the device frame is welded with several sets of support legs, and the support legs are distributed in a rectangular shape.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: Because it is equipped with a stirring roller and a stirring rod, when the plastic raw material enters the feeding cone hopper, the stirring roller and stirring rod can promptly disperse it, preventing the raw material from clogging or agglomerating in the feeding cone hopper and affecting feeding. It also allows the plastic raw material to quickly contact the feeding auger, accelerating the feeding speed. With the feeding pipe splicing flange, the feeding inclined pipe can be divided into upper and lower sections. When the feeding device is not in use, it can be disassembled for convenient transportation, or it can be opened for timely cleaning if there is internal material blockage. Furthermore, after the feeding inclined pipe is disassembled, the dust inside and on its surface can be cleaned. With the slowing cloth bag, when the plastic granules are discharged, the descending material is slowed and its falling direction is changed by the slowing cloth bag, preventing the material from scattering outside and causing material waste, thus creating a better production environment.

[0018] Example
[0019] Please see Figure 1-4 This utility model provides the following technical solution: a feeding device for plastic product production, including a device frame 1 and a feeding conical hopper 4. The feeding conical hopper 4 is welded to the top of the device frame 1, and a feeding motor 2 is fixed to the bottom of the device frame 1. A feeding auger is provided inside the feeding conical hopper 4. The feeding motor 2 is connected to the feeding auger through a pulley set. A stirring motor 3 is fixed to the side of the feeding conical hopper 4, and a stirring roller 5 is also provided inside the feeding conical hopper 4. The stirring roller 5 is connected to the stirring motor 3. It also includes a feeding inclined pipe 7, which is divided into upper and lower sections. A feeding pipe splicing flange 6 is provided at the connection between the upper and lower sections of the feeding inclined pipe 7 and is connected and fixed through the feeding pipe splicing flange 6. The lower section of the feeding inclined pipe 7 is fixed on the feeding conical hopper 4, and the feeding auger is provided inside the feeding inclined pipe 7. A discharge vertical pipe 8 is provided at the top of the feeding inclined pipe 7, and the discharge vertical pipe 8 and the feeding inclined pipe 7 are welded and fixed.
[0020] To make the material feeding process smoother, a slowing cloth bag 9 is provided at the bottom of the feeding vertical tube 8 in this utility model. The feeding vertical tube 8 and the slowing cloth bag 9 are screwed together and fixed.
[0021] In order to disperse the internal raw materials, the surface of the dispersing roller 5 in this invention is provided with multiple dispersing rods 51 at equal intervals. The lengths of the dispersing rods 51 are different, and the lengths of the dispersing rods 51 are adapted to the internal space of the feeding cone hopper 4.
[0022] In order to allow the feeding inclined tube 7 to be disassembled, the feeding tube splicing flange 6 in this utility model is provided with multiple easy-to-disassemble screw holes, which are arranged in a ring array and fixed by external bolts.
[0023] In order to convey and feed materials and to disperse the raw materials, the feeding motor 2 and the dispersing motor 3 in this utility model are electrically connected to an external power source. The feeding motor 2 is a Y-series three-phase asynchronous gear reducer motor, specifically model Y100L1-4, and the dispersing motor 3 is a Y90S-4 type 1.1kW motor.
[0024] In order to extend the service life of the feeding cone hopper 4, the inner wall of the feeding cone hopper 4 in this utility model is provided with a wear-resistant layer, and the wear-resistant layer is made of ceramic coating material.
[0025] In order for the device to be placed stably, the bottom of the device frame 1 in this utility model is welded with several sets of support feet, and the support feet are distributed in a rectangular shape.
[0026] In summary, the working mechanism based on the above-described technical solution of this utility model is as follows:
[0027] Connect the feeding motor 2 and the agitating motor 3 to an external power source and start them. The feeding motor 2 drives the internal feeding auger to rotate, conveying the material entering the feeding cone hopper 4.
