Weighing, pouring and spreading mechanism for flexible polishing pad production

Abstract

The invention discloses a weighing, pouring and spreading mechanism for flexible polishing pad production. The weighing, pouring and spreading mechanism comprises a weighing and pouring mechanism anda spreading mechanism arranged on the downstream of the weighing and pouring mechanism; the weighing and pouring mechanism comprises a screw rod scale, an electronic scale, a weighing hopper and a pouring control device; the weighing hopper is of a two-half structure which comprises a hopper body structure, wherein the hopper body structure is formed by two half hopper bodies which are spliced, the lower part is small and is spliced to be closed, and the upper part is large and open; a hopper supporting shaft transversely penetrating through the upper end of the weighing hopper is arranged atthe upper end of the weighing hopper, and the two half hopper bodies are rotatably connected with the hopper supporting shaft; the two half hopper bodies are in a two-half closed state under the gravity effect natural state; and the spreading mechanism comprises one or more spreading units which are composed of rotating discs, scraping plates and scraping lifting structures. The mould feeding accuracy can be guaranteed, accurate flat spreading is achieved, the scrap rate is decreased, and high automation and high intelligent control is achieved advantageously.

Description

technical field [0001] The invention relates to the technical field of feeding and spreading powdery materials in the production of soft abrasive sheets, in particular to a weighing, discharging and spreading mechanism for the production of soft abrasive sheets. Background technique [0002] The main component of the resin soft grinding disc is a diamond grinding and polishing tool with epoxy resin or phenolic resin as the main binder. It is used for special-shaped processing of stone, ceramics, floor tiles and other materials. It is suitable for stone polishing, line chamfering, curved plate and special-shaped stone processing, and can also be used for marble, concrete, cement floors, terrazzo, glass-ceramic, artificial Special-shaped processing, repair and renovation of stone, floor tiles, glazed tiles, and vitrified tiles. [0003] At present, the production steps of resin soft abrasive discs are roughly divided into: manually use a material spoon to obtain the material ...

AI Technical Summary

Problems solved by technology

[0004] The existing production line of resin soft grinding sheet has the following defects: 1. In the process of taking materials, weighing materials, spreading materials, molds being transported into the press, transported out of the press, and unloading the molds are all done manually, and the labor intensity of the workers is high. The labor rate is low. In the current social labor shortage, the country advocates the background of industry 2025. Highly automated and highly intelligent equipment is required by the society.

2. Due to the thin thickness of the resin soft grinding disc, the thickness after molding is 2.5mm, so the precision of the spread is particularly high. If the spread is not uniform, there will be air holes in places with less powder, resulting in waste products

In the field of various soft grinding disc manufacturers, there are often porosity in the products, resulting in a certain reject rate
