Problems solved by technology

This equipment can realize the complete automation of BMC material division, weighing and shaping, but it is only suitable for small batches of BMC materials
For large batches of BMC materials, the equipment has the following problems: (1) The efficiency of vacuuming the sealed cavity is low, and there is no need to consider the gas in the material gap during the initial packaging; (2) Although the screw push can make the material more Uniform, quantified according to the stroke, but the efficiency is very low, no accurate quantification is required for preliminary packaging; (3) Due to the extremely high hardness of the glass fiber in the BMC material, the active cutting resistance of large-area BMC materials is too large , cannot complete the split
[0005] At present, there is no special equipment in the industry that can be used for the initial packaging of large batches of BMC materials just taken out of the kneader

Embodiment 1

[0046] See figure 1 and figure 2 , The BMC material packaging device of this embodiment includes a box body 1, a pressing mechanism 2, a flat pushing mechanism 3, a feeding mechanism 4, a cutter 5 and a base 6. The box body 1 is fixedly connected to the base 6 and is located on the front side of the base 6 . The box body 1 is surrounded by a 10mm thick stainless steel plate, and the size of the box body 1 is 200mm×1320mm×1200mm.

[0047] The bottom of the front side of the box body 1 is provided with a discharge opening 11 across the width direction of the box body 1 . The size of the discharge port 11 is 1300mm×200mm. The rear top of the box body 1 is provided with a feed opening 12 across the width direction of the box body 1 . The size of the feed port is 1300mm×650mm. The bottom of the box body 1 is also provided with five partitions 13 vertically arranged along the front and rear directions, the bottom of the partitions 13 are welded and fixed on the bottom plate of...

Embodiment 2

[0056] The rest of the BMC material subpackaging device of the present embodiment is identical with embodiment 1, and difference is: as Figure 8 As shown, the bottom of the box body 1 is not provided with a partition 13 .

[0057] The translation mechanism 3 also includes a translation bearing 33 and a translation guide column 34 matched with the translation bearing 33 . There is only one push pedal 32, and the area of ​​the push pedal 32 matches the area of ​​the discharge port 11. There are two groups of translation bearings 33 and translation guide posts 34, and each translation bearing 33 is fixedly connected to the rear side bottom of the casing 1 by its bearing seat. The translation guide post 34 extends into the box body 1 through the corresponding translation bearing 33 and is fixedly connected with the push plate 32 . Translation cylinder 31 has three groups, and translation cylinder 31 is horizontally arranged, and translation cylinder 31 is fixedly connected on t...

Abstract

The invention relates to a BMC (Bulk Molding Compound) material packaging device which comprises a box body, a pressing mechanism, horizontal pushing mechanisms and a cutter; the bottom of the front side of the box body is provided with a discharge outlet, and the rear side of the box body is provided with a feed inlet; the pressing mechanism comprises a pressing plate and a lifting power assembly, and the pressing plate is positioned in the box body; each horizontal pushing mechanism comprises a pushing plate and a translation power assembly; the pushing plates are positioned in the box body and are opposite to the position of the discharge outlet; the cutter, which is strip-shaped, is arranged along the top of the discharge outlet and traverses the discharge outlet, and the cutter is fixedly connected to the box body; the rear side of the bottom surface of the cutter is provided with a row of inclined notchs which are arranged at intervals. The BMC material packaging device is capable of extruding and cutting a large-area BMC material, and is high in working efficiency; after being packaged, the materials are compact, and the volume difference between the materials is small.

Description

technical field [0001] The invention relates to a material subpackaging device, which belongs to the field of mechanical manufacturing. Background technique [0002] BMC material is the abbreviation of Bulk molding compounds, that is, bulk molding compound. It is often called unsaturated polyester bulk molding compound in China. It is a mass made of GF (chopped glass fiber), UP (unsaturated resin), MD (filler calcium carbonate) and various additives through a kneader. shape prepreg. BMC bulk molding compound has excellent electrical properties, mechanical properties, heat resistance, chemical corrosion resistance, and is suitable for various molding processes, which can meet the performance requirements of various products, so it is widely used. [0003] After the BMC material is mixed and taken out of the kneader, it is a large group of flocculent substances with high viscosity and uneven density. Usually, the method of manual tearing is used for preliminary packaging, an...
