Abstract
The utility model discloses a feeding system for a lithium battery diaphragm production line. The feeding system comprises a small storage bin (1), material tubes (2) and an extruder (3), wherein a discharge opening of the small storage bin (1) is connected with an inlet of the extruder (3), two material tubes (2) are arranged, one ends of the two material tubes (2) extend into the small storage bin (1), and the other ends of the two material tubes (2) are fixedly connected with a weightlessness balance (4). With the adoption of the structure, a master batch and additives are measured by the weightlessness balance according to certain proportion, and the feeding dosage is changed according to the speed of the extruder so that the master batch and the additives can enter in the extruder according to certain proportion all the time, finally material mixing uniformity is guaranteed, and secondary granulation is not needed.
Description
Technical field
The utility model relates to a kind of feed system, especially a kind of feed system for lithium battery diaphragm production line.
Background technology
In the production process of lithium battery diaphragm, raw material is that the additive by masterbatch and minute quantity mixes, additive directly affects the formation of lithium battery diaphragm micropore, so the even uniformity consistency that has determined barrier film micropore distributed number and pore size that mixes of masterbatch and additive, this also becomes one of key of producing by high-quality barrier film.Existing lithium battery diaphragm production line, raw material need to enter extruder after small feed bin is piled up, because additive is few with respect to the amount of masterbatch, can't guarantee the uniformity of batch mixing ratio, traditional method is secondary granulation, its method is masterbatch and additive to be sent into extruder high-temperature fusion extrusion after mix and blend according to a certain percentage go out raw material, and through secondary granulation, masterbatch and additive just can evenly mix.But the method can be brought several drawbacks: 1, the rising of raw materials melt index and fluctuation, and molecular chain structure is destroyed, and has reduced machinery and the mechanical property of material; 2, can make material produce degradation product under high temperature action, thereby affect film forming and the physicochemical property of product; 3, secondary granulation needs Granulation Equipments and energy resource consumption, has increased production cost.
The utility model content
The purpose of this utility model is to solve the problem that needs secondary granulation in existing lithium battery diaphragm production process.
The technical solution adopted in the utility model is: the feed system that is used for lithium battery diaphragm production line, it comprises small feed bin, material pipe, extruder, the discharging opening of described small feed bin is connected with the entrance of extruder, described material pipe has two, and an end of two material pipes stretches in described small feed bin, the other end of two material pipes is fixedly connected with weightless the title.
The beneficial effect that the utility model adopts is: after having adopted this structure, weightless claim to measure according to a certain percentage that the speed according to extruder changes inlet amount after masterbatch and additive, thereby make masterbatch and additive enter according to a certain percentage all the time extruder, thereby the uniformity that has guaranteed batch mixing does not need to carry out secondary granulation.
Description of drawings
Fig. 1 is the utility model schematic diagram.
Shown in figure: 1 small feed bin, 2 material pipes, 3 extruders, 4 weightless titles.
The specific embodiment
Below in conjunction with Fig. 1, the utility model is described further.
As shown in Figure 1, the utility model relates to a kind of feed system for lithium battery diaphragm production line, it comprises small feed bin 1, material pipe 2, extruder 3, the discharging opening of described small feed bin 1 is connected with the entrance of extruder 3, described material pipe 2 has two, and an end of two material pipes 2 stretches in described small feed bin 1, the other ends of two material pipes 2 are fixedly connected with and weightlessly claim 4.
At first the utility model adds respectively with masterbatch and additive the upper Weightlessness balance that is positioned at 2 material pipes in use, add rear Weightlessness balance to bring into operation, in the process of Weightlessness balance operation, weightless claim to measure according to a certain percentage that the speed according to extruder changes inlet amount after masterbatch and additive, after masterbatch and additive metering, logical charge tube enters small feed bin and then enters extruder, thereby makes masterbatch and additive enter according to a certain percentage all the time extruder.
In sum, after having adopted this structure, weightless claim to measure according to a certain percentage that the speed according to extruder changes inlet amount after masterbatch and additive, thereby make masterbatch and additive enter according to a certain percentage all the time extruder, thereby the uniformity that has guaranteed batch mixing does not need to carry out secondary granulation.
Claims (1)
