Abstract

The utility model relates to a machine which is used for producing net cloth made from abrasive sand. A plurality of rows of steel needles are uniformly arranged on two closed chains arranged in parallel; the two closed chains are driven by a chain wheel; both sides of the net cloth after dipped in glue are sheathed on the steel needles to run with the chains. A vane wheel which rotates in high speed is arranged below a gravity sand feeding hopper and the net cloth; one part of sand falling down from the sand feeding hopper is stuck to the upward surface of the net cloth; the other part of the sand falling down from the sand feeding hopper passes through net holes to fall on the vane wheel which rotates in high speed, and is immediately thrown upward by the vane wheel to be stuck to the downward surface of the net cloth to be dried and shaped with rapidness and saving. Because the steel needles are arrayed uniformly, the net cloth has uniform stress and good smoothness; owing to simple structure, the utility model has low cost.

Description

A kind of production abrasive material abrasive cloth machine

The utility model is a kind of machine that is used to produce the abrasive sand screen cloth.

The cloth clamp clamping selvedge operation that is contained on the chain is all adopted in the operation of the production abrasive sand screen cloth machine screen cloth in the process of planting sand and drying that uses now, the space that exists between such two cloth clamps, be screen cloth folder less than part yielding, have influence on the flatness of screen cloth.At present the production abrasive sand screen cloth machine that uses is planted the sand mode two kinds, plants sand for gravity for first kind, plants screen cloth one side up behind the impregnation by the gravity of abrasive sand self, then screen cloth is planted another side conversely, and production efficiency is low like this, and abrasive sand is wasted many.Second kind is electrostatic sand-planting, because low order sand weight is big, and the electrostatic means weak effect, and cost is expensive.

The purpose of this utility model be to provide that a kind of crudy is good, efficient, material-saving, widely applicable and novel production abrasive material screen cloth machine that cost is low.

For achieving the above object, the technical solution adopted in the utility model is: evenly plant number row draw point on two closed chains that are arranged in parallel by sprocket wheel drive moving linearly, the screen cloth both sides behind the impregnation are enclosed within on the draw point to be moved with chain.Gravity plant sand hopper and screen cloth below increase by the impeller of rotation at a high speed, adhere to screen cloth one side up from planting the sand part that sand hopper falls, a part is passed mesh and is fallen on the impeller blade of rotation at a high speed, under action of centrifugal force sand by throw to screen cloth down one side and be glued, be dried into type then.

The utility model has the advantages that because draw point is arranged evenly, screen cloth is stressed evenly, so the flatness of screen cloth is good, the quality height.Because sand is implanted in the two sides of screen cloth simultaneously by gravity and centrifugal force, thus efficient height, material-saving and be suitable for all orders and count sand, since simple in structure, so cost is low.So the utlity model has practical and popularizing value.

Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing:

Accompanying drawing is the general structure schematic diagram that the utility model is produced abrasive sand screen cloth machine.

With reference to accompanying drawing, two closed chains that are arranged in parallel (1) mesh with two groups of sprocket wheels (2) respectively, and with its rotation moving linearly, screen cloth is through roller (3), (4) behind the impregnation, the mesh on its both sides is enclosed within on the single-row draw point (5) that evenly is planted on two chains (1), when running to funnel (6) below with it, an emergy part that falls from funnel (6) adheres to screen cloth one side up, a part is passed mesh and is fallen on the impeller (7) that is positioned at its below high speed rotation, and adhere to screen cloth simultaneously down above being thrown to by it immediately, not only soon but also economize, the screen cloth that the two sides is stained with sand simultaneously continued with chain (1) forward by radiator (8) heating, drying.The overall process that screen cloth is planted sand and oven dry all is enclosed within on the equally distributed draw point (5), so the stressed even flatness of screen cloth is good, and screen cloth disengagement draw point (5) batches moulding and makes the emergy screen cloth then.

Claims

1, a kind of production abrasive material abrasive cloth machine is made up of two parallel closed chains (1), two groups of sprocket wheels (2), funnel (6).It is characterized in that: chain (1) is with sprocket wheel (2) engagement and evenly planted draw point (5), is used to catch on screen cloth both sides linear running.

2, production abrasive material abrasive cloth machine according to claim 1 is characterized in that: the impeller (7) of rotation at a high speed is equipped with in the below of funnel (6), is used for the sand that falls is thrown to the top.
