Description

Technical Field

[0001] This utility model relates to the field of injection molding machine equipment technology, and in particular to a feeding device for a vertical injection molding machine. Background Technology

[0002] In the injection molding process, the quality and condition of the raw materials have a crucial impact on the quality of the final plastic products. For vertical injection molding machines, traditional feeding methods often lack effective pretreatment of the raw materials. For example, the raw materials may contain a certain amount of moisture. During the injection molding process, the moisture evaporates when heated, which can lead to defects such as bubbles and silver streaks in the product, seriously affecting its appearance and mechanical properties. Moreover, the particle size of the raw materials varies. If unscreened raw materials are directly added to the injection molding machine, particles that are too large or too small may cause instability in the injection molding process, such as clogging the nozzle and affecting the plasticizing effect, thereby reducing production efficiency and product qualification rate. Utility Model Content

[0003] The main purpose of this utility model is to provide a feeding device for a vertical injection molding machine, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a vertical injection molding machine feeding device, including a support frame, a storage mechanism is provided on the upper side of the support frame, a screening mechanism is provided at the lower part of the storage mechanism, and a conveying mechanism is provided at the lower part of the screening mechanism;

[0005] The storage mechanism includes a tank body, a tank cover, a shaft, a stirring blade, and a geared motor. The lower part of the tank cover is located on the upper part of the tank body. The middle part of the stirring blade is fixedly connected to the outer periphery of the shaft. The upper end of the shaft passes through and is rotatably connected to the middle part of the tank cover. The geared motor is installed on the upper middle part of the tank cover. The lower output end of the geared motor passes through the tank cover and is fixedly connected to the upper end of the shaft. A solenoid valve is provided at the lower end of the tank body.

[0006] Preferably, a cavity is provided in the middle of the tank wall shell, and an electric heating wire is provided inside the cavity. An exhaust pipe is provided in the middle of the tank cover, and a filter screen is provided inside the exhaust pipe.

[0007] Preferably, the screening mechanism includes a connecting frame, multiple springs, a screening disc, a slag discharge pipe, a bellows cover, and a vibrating motor. The upper ends of the multiple springs are fixedly connected to the lower outer periphery of the tank body, and the lower ends of the multiple springs are fixedly connected to the upper part of the connecting frame. The upper part of the screening disc is fixedly connected inside the connecting frame. One end of the slag discharge pipe is installed on one side of the screening disc. The vibrating motor is installed on the lower part of the connecting frame. The lower part of the screening disc is connected to the conveying mechanism through the bellows cover, and the upper part of the connecting frame is installed on the lower part of the tank body through the bellows cover.

[0008] Preferably, the bottom of the screening disc slopes towards the slag discharge pipe.

[0009] Preferably, the conveying mechanism includes a receiving tray, an ejector, a conveying pipe, and a fan.

[0010] Preferably, the end of the conveying pipe away from the blower is installed on the side wall of the hopper of the vertical injection molding machine.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. By energizing the heating wire, the raw materials inside the tank are heated, driving the geared motor, which in turn drives the stirring blades to rotate via the shaft. This stirs and dries the raw materials inside the tank, and the moisture is discharged through the exhaust pipe. The rotating stirring blades also break up any clumps of raw materials, removing moisture and improving the quality of the injection molded products.

[0013] 2. The drive vibration motor causes the connecting frame to shake. Due to the inclination of the bottom of the screening disc, the raw materials with qualified particle size fall into the receiving disc and are conveyed away, while the large particles roll along the inclination of the bottom of the screening disc and are finally discharged from the slag discharge pipe, thereby ensuring the uniformity of the raw material particle size and improving the quality of injection molded products.

[0021] In this embodiment, the storage mechanism 2 includes a tank body 201, a tank cover 202, a shaft 203, a stirring blade 204, and a reduction motor 205. The lower part of the tank cover 202 is disposed on the upper part of the tank body 201. The middle part of the stirring blade 204 is fixedly connected to the outer periphery of the shaft 203. The upper end of the shaft 203 passes through and is rotatably connected to the middle part of the tank cover 202. The reduction motor 205 is installed on the upper middle part of the tank cover 202. The lower output end of the reduction motor 205 passes through the tank cover 202 and is fixedly connected to the upper end of the shaft 203. A solenoid valve is disposed at the lower end of the tank body 201. A cavity 209 is disposed in the middle of the wall shell of the tank body 201. An electric heating wire 208 is disposed inside the cavity 209. An exhaust pipe 206 is disposed in the middle of the tank cover 202. A filter screen 207 is disposed inside the exhaust pipe 206.

[0022] Specifically, the heating wire 208 is energized to heat the raw material inside the tank 201, driving the geared motor 205 to rotate the stirring blade 204 via the shaft 203, thereby stirring and drying the raw material inside the tank 201. Moisture is discharged through the exhaust pipe 206, and the rotating stirring blade 204 breaks up the clumps of raw material, removes moisture, and improves the quality of the injection molded product.

[0023] In this embodiment, the screening mechanism 3 includes a connecting frame 301, multiple springs 302, a screening disc 303, a slag discharge pipe 304, a bellows cover 305, and a vibrating motor. The upper ends of the multiple springs 302 are fixedly connected to the lower outer periphery of the tank body 201, and the lower ends of the multiple springs 302 are fixedly connected to the upper part of the connecting frame 301. The upper part of the screening disc 303 is fixedly connected to the inside of the connecting frame 301. One end of the slag discharge pipe 304 is installed on one side of the screening disc 303. The vibrating motor is installed at the lower part of the connecting frame 301. The lower part of the screening disc 303 is connected to the conveyor belt via the bellows cover 305. The mechanism 4 is connected. The upper part of the connecting frame 301 is installed on the lower part of the tank body 201 through the bellows cover 305. The bottom of the screening plate 303 slopes towards the slag discharge pipe 304. The conveying mechanism 4 includes a receiving plate 401, an ejector 402, a conveying pipe 403 and a blower 404. The lower part of the receiving plate 401 is installed on the upper part of the ejector 402. The left and right ends of the ejector 402 are installed in the middle of the conveying pipe 403. The output end of the blower 404 is installed at one end of the conveying pipe 403. The end of the conveying pipe 403 away from the blower 404 is installed on the side wall of the hopper of the vertical injection molding machine.

[0024] Specifically, the drive motor vibrates the connecting frame 301, and because the bottom of the screening disc 303 is tilted, the raw material with the qualified particle size falls into the receiving disc 401 and is conveyed away, while the large particles roll along the tilted bottom of the screening disc 303 and are finally discharged from the slag discharge pipe 304, thereby ensuring the uniformity of the raw material particle size and improving the quality of the injection molded product.

[0025] Working principle:

[0026] The heating wire 208 is energized to heat the raw material inside the tank 201, driving the geared motor 205 to rotate the stirring blade 204 via the shaft 203. This stirs and dries the raw material inside the tank 201, and the moisture is discharged through the exhaust pipe 206. The rotating stirring blade 204 also breaks up clumps of raw material, removes moisture, and improves the quality of the injection molded product. The vibration motor is driven to make the connecting frame 301 shake. Due to the inclination of the bottom of the screening disc 303, raw material of the correct particle size falls into the receiving disc 401 and is transported away, while large particles roll along the inclination of the bottom of the screening disc 303 and are finally discharged from the slag discharge pipe 304. This ensures the uniformity of the raw material particle size and improves the quality of the injection molded product.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
