Powdery paints turnover plate type dust elimination sack-filling device
Technical field
The present invention relates to a kind of powder coating processing device, particularly relate to a kind of powdery paints turnover plate type dust elimination sack-filling device。
Background technology
China is world manufacturing center, need every year to consume substantial amounts of coating, existing coating mostly is the liquid type prepared, the necessary barreled cost of transport is high, unit dose ratio is great, climate affects transport and storage in winter and all easily endures cold rotten, restricted by these factors, powdery paints was developed rapidly in recent years, it is low that it has packed cost, storage transport takes up room little, compare unit dose proportion little, there is no volume dilution weatherproof, avoid the loss endured cold, reduce cost of warehousing transportation in winter further, along with the needs that the yield of powdery paints is increased production, its manufacture equipment does not but have big technological progress, still have some shortcomings part, as in dust leakage, in production, to be typically all closed cycle dust leakage little for flour mill and feed bin, and the powder prepared with flour mill have to pass through pack after entering feed bin and just can dispatch from the factory, when pack, packaging bag is vertical, inner air is many, seal bad with discharging opening, impact when powdery paints falls in bag, produce a large amount of dust, in bag, air is extruded bag mouth with filling in of powdery paints in bag, dust also goes out with flow leakage, production environment is worked the mischief, not only affect staff healthy, it is also easy to cause dust storm catastrophic failure, this problem still awaits solving, promote the development of powdery paints industry。
Summary of the invention
In order to solve the problems referred to above, the invention provides a kind of powdery paints turnover plate type dust elimination sack-filling device。
The technical solution used in the present invention is: a kind of powdery paints turnover plate type dust elimination sack-filling device, discharging opening including feed bin and feed bin bottom, it is characterized in that discharging opening cross section is rectangle, the left and right of discharging opening is respectively arranged at two ends with the expansion block engaged with discharging opening, the front and back of discharging opening are respectively provided on two sides with elastic force intermediate plate, and discharging opening is provided with opening and closing flashboard;Discharging opening is connected with an overall L-shaped turnover panel, and turnover panel upper end thereof, on support, is provided with the elastic body popped up by turnover panel between turnover panel and support, support is provided with support beam, support beam with under the turnover panel lower end turned over only support。
Further, described elastic body is cylinder。
Further, described elastic body is spring。
Further, described expansion block side is curved surface。
Further, described expansion block horizontal section area is gradually reduced downwards。
The present invention selects the expansion block of suitable dimension to be stuck in discharging opening two ends according to mouth size before using, make its girth adaptive with bag mouth girth, then clamping elastic force intermediate plate, bag lies on the turnover panel turned over, keep flat bag in retain little air, powdery paints flows out discharging opening and falls directly in the bag on turnover panel, the little impact of drop little dust generation amount is little, along with the increasing injecting bag powdery paints weight, turnover panel overcomes the elastic force of elastic body to turn over down gradually, at the bottom of powdery paints slips into bag, impact little dust generation amount little, support beam to support after only with turnover panel lower end, continue latter end fill, until completing;This device discharging opening and bag mouth good seal, in pouring process bag, generation dust is few, and in bag, reserved little air leakage is few, and to protecting staff healthy and avoiding dust storm accident benefit the more, simple in construction is easy to implement, is suitable to popularization and application。

Detailed description of the invention
The invention process such as Fig. 1 is to shown in 2, this powdery paints turnover plate type dust elimination sack-filling device, discharging opening including feed bin 1 and feed bin bottom, discharging opening cross section is rectangle, the left and right of discharging opening is respectively arranged at two ends with the expansion block 2 engaged with discharging opening, expansion block side is curved surface, and the front and back of discharging opening are respectively provided on two sides with elastic force intermediate plate 3, and discharging opening is provided with opening and closing flashboard 4;Discharging opening is connected with an overall L-shaped turnover panel 5, turnover panel upper end thereof on the frame 6, is provided with the elastic body popped up by turnover panel between turnover panel and support, the present embodiment elastic body is cylinder 7, support is provided with support beam 8, support beam with under the turnover panel lower end turned over only support。The present invention selects the expansion block of suitable dimension to be stuck in discharging opening two ends according to mouth size before using, make its girth adaptive with bag mouth girth, then clamping elastic force intermediate plate, bag lies on the turnover panel turned over, keep flat bag in retain little air, powdery paints flows out discharging opening and falls directly in the bag on turnover panel, the little impact of drop little dust generation amount is little, along with the increasing injecting bag powdery paints weight, turnover panel overcomes the elastic force of elastic body to turn over down gradually, at the bottom of powdery paints slips into bag, impact little dust generation amount little, support beam to support after only with turnover panel lower end, continue latter end fill, until completing;This device discharging opening and the little good seal in bag mouth gap, in pouring process bag, generation dust is few, and in bag, reserved little air leakage is few, and to protecting staff healthy and avoiding dust storm accident benefit the more, simple in construction is easy to implement, is suitable to popularization and application。
During the invention process, elastic body can be also spring;Expansion block form can be that horizontal section area is gradually reduced downwards shape, it is simple to being inserted in of bag mouth。
Being only present pre-ferred embodiments in sum, all equivalences done according to the application are modified and prior art interpolation is accordingly to be regarded as the technology of the present invention category。
