Description
Technical field
The utility model relates to lithium battery diaphragm compounding machine equipment technical field, refers in particular to a kind of axis that unreels of lithium battery diaphragm compounding machine here.
Background technology
In the structure of lithium cell, barrier film is one of crucial interior layer assembly, the performance of barrier film has determined the interfacial structure, internal resistance of battery etc., directly influences the characteristics such as capacity, circulation and safety performance of battery, and the barrier film of excellent performance has important effect to the Combination property that improves battery.Barrier film adopts plastic film to make, and can isolate battery plus-negative plate, to prevent short circuit; Can also be when battery be overheated, intercept conduction of current in the battery by the closed pore function.The description of the popular point of barrier film is exactly the pory plastic sheeting of one deck, it is the highest a kind of high added value material of technology barriers in the lithium electric material, account for the 20%-30% of lithium cell cost, the major cause that barrier film holds at high price is that some gordian techniquies of making barrier films are monopolized by the Japan and the U.S., and the homemade barrier film particularly index of high-end barrier film does not also reach the level of external product.
The membrane technique difficult point is the engineering branch art and the basis material of pore-creating.Wherein the engineering technology of pore-creating comprises barrier film pore-creating technology, production facilities and product stability.That the basis material of barrier film comprises is poly-third bright, polythene material and additive.The barrier film production technology can be divided into two big classes according to dry method and wet method at present, and dry method can be subdivided into unilateral stretching technology and stretch processes again simultaneously.Dry method unilateral stretching technology is by producing the method for hard elastic fibre, prepare the high oriented polypropylene or the polyethylene foil of low-crystallinity, obtaining the oriented film of high-crystallinity at high temperature annealing.The first formation microdefect that stretches at low temperatures of this film makes defective draw back, form micropore then under the high temperature.This technology is very ripe in the U.S., Japan through the development of decades, and this arts demand equipment is very complicated, equipment precision requirement is very high, and whole technology is quite complicated, control difficulty height.The barrier film micropore of producing requires size, it is all very even to distribute, and the micropore conduction is good, can produce the barrier film of different-thickness, can adopt PP, PE material to produce.Because gordian technique is grasped in Japan and u s company, domestic manufacturer does not also grasp this technology, does not therefore also process the specialized equipment of this product.
Wet method claims phase separation method or thermally induced phase separation again.High boiling hydrocarbon liquids or low the branch in the material of amount are mixed with polyolefin resin, heat and dissolve solvate and melt is layered on the thin slice, lowering the temperature then is separated, again with vertical or black soy sauce to the time thin slice do orientation process.Use highly volatile solvent extraction liquid at last.Can prepare the microporous membrane material of mutual perforation.Barrier film with the production of wet method bidirectional extending method has higher vertical and horizontal intensity owing to passed through biaxial tension.Be mainly used in single layer PE barrier film at present.This arts demand equipment is also very complicated, whole process flow is quite complicated, and cost height, energy consumption are big, but the barrier film pore size of producing, distributes very evenly, and the micropore conduction is good, produces thin barrier film easily, can adopt the PE material to produce.
At present, domestic employing barrier film processing technology is a stretch processes, by in polypropylene, adding crystal formation improver with nucleation, utilize the difference of density between the different phases of polypropylene, crystal transfer takes place in drawing process form micropore, be used to produce individual layer PP film, perhaps adopt common PP blow molding process to process.As a complete unit, the battery diaphragm of domestic production, pore size, distribute all comparatively inhomogeneous, and poor stability, in order to reach micropore comparatively uniformly, usually way is laminated diaphragm to be carried out compound, can obtain thicker battery diaphragm, can arrive the basic demand of battery diaphragm technology, in can satisfying, low side battery production needs.Barrier film carries out compound, need to adopt the specialized equipment compounding machine to unreel, roll-in, rolling, and in the process of unreeling, the barrier film reel has two kinds of materials usually, and paper web and work durm select for use different materials to be because the decision of the production technology of barrier film.Paper web and work durm diameter are the size criteria size, the directly big slightly work durm diameter of paper web, when unreeling, all may be applied to two kinds of reels, but at present compounding machine unreels axis, and its card unreels axis can only single clamping paper web or work durm, in use, the axis that unreels of work durm or paper web may be needed to change, a lot of inconveniences can be produced during use.
The utility model content
The utility model is at the prior art deficiency, but provide a kind of general-duty paper web or work durm the battery diaphragm compounding machine unreel axis.
The pond barrier film compounding machine that the utility model provides unreel axis, unreeling axis laterally is installed in compounding machine and unreels on the frame, the described axis that unreels comprises that a left side unreels axis and the right side unreels axis, a left side, the right side unreels axis by rotating shaft, bearing, the clamping head, the axis lateral driver device is formed, bearing installation is unreeling on the frame, rotating shaft is installed on the bearing, outside unreeling frame, be provided with lateral driver device, promote rotating shaft to unreeling the frame internal motion, the clamping head is installed the roller end that unreels the frame inboard, the clamping head comprises paper roll clamping shaft part, iron volume clamping shaft part, the all sides of paper roll clamping shaft part axle are provided with spline, establish the clamping key on the iron volume clamping shaft part, iron volume clamping shaft part end diameter is slightly smaller than iron volume clamping shaft part inside diameter, and paper roll clamping shaft part end diameter is slightly smaller than paper roll clamping shaft part inside diameter.
The lateral driver device that described left side card unreels axis is a pneumatic cylinder, and the lateral driver device that right card unreels axis is manual rotary handle.
The beneficial effects of the utility model are: the utility model is provided with paper roll clamping shaft part, iron volume clamping shaft part simultaneously at the same axis that unreels, the barrier film reel of clamping papery as required or the barrier film reel of irony, at paper roll clamping shaft part spline is set, the available barrier film reel of papery that effectively prevents is with respect to the slip that unreels axis damage formula, damage paper web, can accomplish that an axis uses more.
