Description

Technical Field

[0001] This utility model relates to the field of plastic masterbatch conveying technology, and in particular to a material conveying component and a plastic masterbatch conveying device. Background Technology

[0002] Plastic masterbatch is a granular compound made by mixing and granulating plastic raw materials with additives (such as pigments and flame retardants). It can be added to ordinary plastic raw materials to give products coloring, heat resistance and other functions, while simplifying the production process. It is widely used in the production of plastic products such as films and pipes. In the production process of plastic masterbatch, the conveying device is a key material conveying component. It uses spiral, pneumatic and other methods to accurately and stably transport the masterbatch from the storage container to the feed port of the processing equipment, effectively avoiding problems such as moisture and contamination, ensuring the continuity and accuracy of material supply, thereby greatly improving the efficiency of automated production, and becoming an important link between storage and processing.

[0003] However, traditional material conveying devices have the following drawbacks when conveying plastic masterbatch: First, they lack screening functions, and screening and conveying require the coordination of multiple devices, which increases the number of failure points and maintenance costs; Second, single-channel conveying bins cannot simultaneously convey graded materials, resulting in material mixing and affecting the quality of subsequent production. Therefore, we propose a material conveying component and a plastic masterbatch conveying device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing traditional plastic masterbatch conveying devices, such as the lack of screening function and the inability to simultaneously convey graded materials, and to propose a material conveying component and a plastic masterbatch conveying device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A material conveying assembly includes a conveying box, with two support seats fixedly connected to the bottom of the conveying box, and a transmission box fixedly connected to the inner wall of the conveying box. The transmission box divides the interior of the conveying box into a first conveying chamber and a second conveying chamber. A first spiral conveying rod and a second spiral conveying rod are rotatably connected to the first conveying chamber and the second conveying chamber, respectively. A first discharge port and a second discharge port are respectively opened at the bottom of the conveying box in the first conveying chamber and the second conveying chamber.

[0007] A screening box is fixedly connected to the top of the conveyor box. A screening component is set inside the screening box. The screening component includes a screening frame and a driving component that drives the screening frame to move back and forth to achieve screening. After screening, the material is graded according to particle size and introduced into the first discharge bin or the second discharge bin.

[0008] The drive assembly includes a support bracket fixedly mounted on the top of the conveyor box, a drive shaft rotatably mounted inside the support bracket, and a first motor that drives the drive shaft to rotate.

[0009] The top of the screening box is fixedly connected to a hopper, and a dispersing component is rotatably connected inside the hopper. The dispersing component includes two rotating rollers for dispersing clumps of material.

[0010] In one possible design, the screening box is provided with a first discharge bin and a second discharge bin, the first discharge bin being connected to a first conveying bin, and the second discharge bin being connected to a second conveying bin.

[0011] In one possible design, the screening component further includes a screen fixedly connected inside the screening frame at a certain angle, which divides the interior of the screening frame into an upper screening chamber and a lower screening chamber. The bottom of the screening frame has a first outlet connecting the upper screening chamber and a second outlet connecting the lower screening chamber. The first outlet extends into the interior of the first discharge chamber, and the second outlet extends into the interior of the second discharge chamber.

[0012] In one possible design, two grooves are formed on the inner walls of both sides of the screening box, and a sliding rod is fixedly installed in each of the four grooves. Two sliders slide through each sliding rod, and the sliders are fixedly connected to the screening frame.

[0013] In one possible design, the drive assembly includes a connecting rod fixedly connected to one side of the screening box. The connecting rod slides through the screening box and extends into the interior of the support. One end of the connecting rod is fixedly connected to a connecting block. The connecting block has a clearance hole. The drive shaft passes through the clearance hole. An eccentric wheel is fixedly sleeved on the drive shaft inside the clearance hole. The outer wall of the eccentric wheel contacts the inner wall of the clearance hole.

[0014] In one possible design, meshing transmission gears are fixedly sleeved on the rotating shafts of the two rotating rollers, and multiple toothed rods are provided on the outer walls of both rotating rollers, with the multiple toothed rods on the two rotating rollers being staggered.

[0015] In one possible design, a transmission rod is rotatably connected inside the bracket. A sprocket is fixedly fitted on both the transmission rod and the rotating shaft of one of the rotating rollers. The two sprockets are driven by the same chain. A first bevel gear is fixedly fitted on the top of the transmission shaft and the transmission rod. The two first bevel gears are meshed together.

[0016] In one possible design, the ends of the first and second spiral conveying rods that are close to each other both extend into the interior of the transmission box and are fixedly fitted with second bevel gears. A second motor is fixedly connected to one side of the transmission box, and the output end of the second motor extends into the interior of the transmission box and is fixedly fitted with a third bevel gear. Both second bevel gears are meshed with the third bevel gear.

[0017] In one possible design, the plastic masterbatch conveying device includes a material conveying component as described in any of the above-described technical solutions.

[0018] In this application, firstly, plastic masterbatch enters the device from the hopper. At this time, the first motor starts, drives the transmission shaft to rotate, and drives the transmission rod to rotate synchronously through the first bevel gear. The transmission rod drives one of the rotating rollers to rotate through the sprocket and chain. The transmission gear of the rotating roller then drives the other rotating roller to rotate in the opposite direction, so that the two rotating rollers rotate synchronously in opposite directions. This not only breaks up the agglomerated plastic masterbatch in the hopper, but also effectively prevents blockage at the hopper outlet.

[0019] After being broken down, the masterbatch falls into the screening frame inside the screening box. The screen inside the screening frame separates the masterbatch into the upper screening chamber and the lower screening chamber according to the particle size. Specifically, the eccentric wheel on the drive shaft cooperates with the clearance hole of the connecting block to drive the connecting rod and the screening frame to move back and forth along the slide bar, so that the masterbatch moves fully on the screen, improving screening efficiency and accuracy. Masterbatch that does not meet the screen aperture requirements falls into the lower screening chamber through the screen and enters the second discharge chamber through the second outlet; the qualified particles remain in the upper screening chamber and enter the first discharge chamber through the first outlet.

[0020] Finally, the second motor starts, and the third bevel gear at its output end meshes with the second bevel gear at the end of the first and second spiral conveying rods, respectively driving the first and second spiral conveying rods to rotate in the first and second conveying chambers, so as to output masterbatch of different particle sizes from the first and second discharge ports, realizing the simultaneous screening and conveying.

[0021] Beneficial effects: In this utility model, the material conveying component and plastic masterbatch conveying device, through the vibration screening of the inclined screen and the combination of dual outlets, classifies the material according to particle size and introduces it into an independent discharge bin, and then conveys it synchronously to the designated outlet through the double helix conveyor rod, realizing continuous operation of particle size classification and directional conveying, reducing manual intervention, improving sorting accuracy, and avoiding process fluctuations caused by secondary mixing.

[0022] In this utility model, the material conveying component and plastic masterbatch conveying device use a rotating roller with interlocking toothed rods inside the hopper to rotate in the opposite direction through meshing transmission gears, thereby forcibly breaking up agglomerated materials. Its power is provided by the transmission shaft through bevel gears and chain linkage, requiring only a single motor to drive the screening and dispersing components, which not only reduces the risk of blockage but also reduces the need for additional power sources.

[0023] In this utility model, the material conveying component and plastic masterbatch conveying device have a second motor that drives the first and second spiral conveying rods to rotate simultaneously through bevel gears, ensuring efficient power transmission. This transmission method has a compact structure, stable transmission ratio, and can withstand large loads, reducing the probability of transmission failures, extending the service life of the equipment, and reducing energy loss caused by transmission instability.

[0024] In this invention, the inclined screen vibration screening, dual outlets, and double helical conveyor rods work together to achieve particle size classification and directional continuous conveying of materials, reducing manual intervention, improving sorting accuracy, and avoiding secondary mixing. The rotating rollers inside the hopper rotate in opposite directions to break up agglomerated materials, and the single motor linkage screening and dispersing components not only reduce the risk of blockage but also reduce the power source. The double helical conveyor rods are driven by the same motor through bevel gears, resulting in efficient power transmission, a compact and stable structure, and reduced failures and energy consumption.

A first outlet 601 connecting to the upper screening bin and a second outlet 602 connecting to the lower screening bin are formed at the bottom of the screening frame 6. The first outlet 601 extends into the interior of the first discharge bin 401, and the second outlet 602 extends into the interior of the second discharge bin 402.

[0037] In another embodiment: Reference Figure 2-5Based on Embodiment 1, an improvement is made: a material conveying component and a plastic masterbatch conveying device, which is applied to the field of plastic masterbatch conveying technology.

The broken masterbatch falls into the screening frame 6, and the screening frame 6 moves back and forth along the slide bar 11 to screen and classify the masterbatch. Finally, the second motor 19 starts and drives the first spiral conveyor 103 and the second spiral conveyor 104 to output masterbatch of different particle sizes from the corresponding discharge port, so as to realize the simultaneous screening and conveying.

They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.
