Description
Technical field
The utility model belongs to lithium ion battery separator production equipment technical field, the side cutting sewing machine after relating to that a kind of lithium ion battery separator is two and drawing.
Background technology
Lithium ion battery wet method barrier film biaxial tension operation, because barrier film limit is by clip mistake, thickness is thicker, so subsequent processing must could be arrived after trimming, existing trimming mostly utilizes compressed air to be pressed on roller by the circular shear blade of routine, roller drives circular shear blade to rotate, and the rim charge of the barrier film under circular shear blade is cut off automatically.Because circular shear blade is pressed on roller by the pressure continued, and the hardness ratio roller of circular shear blade is large, so the cutter groove on roller is more and more darker, cutter slot is put original metal and is extruded to the place that roller surfaces and cutter groove edge connect, these metal charges reach certain size, must stop production and could clear up by manual grinding, otherwise scuffing can be caused to barrier film, the number of times of the film that breaks when increasing production.According to production leadtime, often produce and polishing roller within 3 days, will be shut down, and the easily broken film of pilot process, cause very large waste, produce yield low.
Summary of the invention
The utility model is in order to overcome the defect of prior art, and the side cutting sewing machine after devising that a kind of lithium ion battery separator is two and drawing, roller can use 30 days continuously, and process stabilization, and continuous film, produces yield and be improved.
The concrete technical scheme that the utility model is taked is: the side cutting sewing machine after a kind of lithium ion battery separator pair draws, comprise frame, roller, cutter mechanism, roller is horizontally disposed with and is formed with frame and is rotatably assorted, roller is wound with barrier film, cutter mechanism comprises crossbeam, tool rest and circular shear blade, crossbeam is fixedly connected with frame, tool rest is arranged on to be formed on crossbeam and with crossbeam and is slidably matched, circular shear blade is arranged on to be formed on tool rest and with tool rest and is rotatably assorted, the axis of circular shear blade with the axis being parallel of roller and the blade of circular shear blade contact with the barrier film of roller surfaces, key is: offer multiple groove vertically on the surface of roll end, groove and circular shear blade are oppositely arranged, groove along roller axle to width equal with the thickness of circular shear blade.
The degree of depth of described groove is 2 ~ 5mm.
Spacing between described adjacent grooves is 2 ~ 6mm.
Described frame comprises base plate and two side plates vertically arranged, two side plates are symmetricly set on the two ends of base plate and are fixedly connected with base plate, roller mount is located to be formed between two side plates and with two side plates and is rotatably assorted, and beam erection is between two side plates and be fixedly connected with two side plates.
The beneficial effects of the utility model are: position fluting corresponding on roller under circular shear blade, according to the width of the thickness determination groove of circular shear blade, circular shear blade is directly pressed onto bottom portion of groove, when barrier film runs into circular shear blade, due to the longitudinal tensioning of barrier film, laterally oil is had to make barrier film be bonded at roller surfaces, namely cut by circular shear blade so barrier film does not arrive bottom portion of groove, the smooth non-notch of trimming, can not cause disconnected film during production thus, and yield rate promotes, roller can use 30 days continuously, and process stabilization, continuous film, substantially increases production yield.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In accompanying drawing, 1 represents frame, and 2 represent roller, and 3 represent circular shear blade, and 4 represent crossbeam, and 5 represent tool rest, and 6 represent groove.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated:
Specific embodiment, as shown in Figure 1, side cutting sewing machine after a kind of lithium ion battery separator pair draws, comprise frame 1, roller 2, cutter mechanism, roller 2 is horizontally disposed with and is formed with frame 1 and is rotatably assorted, roller 2 is wound with barrier film, cutter mechanism comprises crossbeam 4, tool rest 5 and circular shear blade 3, crossbeam 4 is fixedly connected with frame 1, tool rest 5 is arranged on to be formed on crossbeam 4 and with crossbeam 4 and is slidably matched, circular shear blade 3 is arranged on to be formed on tool rest 5 and with tool rest 5 and is rotatably assorted, the axis of circular shear blade 3 with the axis being parallel of roller 2 and the blade of circular shear blade 3 contact with the barrier film on roller 2 surface, multiple groove 6 is offered vertically on the surface of roller 2 end, the degree of depth of groove 6 is 2 ~ 5mm, spacing between adjacent grooves 6 is 2 ~ 6mm, groove 6 and circular shear blade 3 are oppositely arranged, groove 6 is equal with the thickness of circular shear blade 3 along the width of roller 2 axis.
Described frame 1 comprises base plate and two side plates vertically arranged, two side plates are symmetricly set on the two ends of base plate and are fixedly connected with base plate, roller 2 is erected to be formed between two side plates and with two side plates and is rotatably assorted, and crossbeam 4 to be erected between two side plates and to be fixedly connected with two side plates.Structure is simple, solid and reliable.
The utility model is in the specific implementation: the width of the rim charge excised first as required, the adjustment position of tool rest 5 on crossbeam 4, directly over the groove 6 that circular shear blade 3 is just in time positioned at corresponding to cutting position, then roller 2 is made to rotate, roller 2 drives circular shear blade 3 to rotate, when barrier film runs into circular shear blade 3, due to the longitudinal tensioning of barrier film, oil is laterally had to make barrier film be bonded at roller 2 surface, namely cut by circular shear blade 3 so barrier film does not arrive bottom groove 6, the smooth non-notch of trimming, disconnected film can not be caused thus during production, yield rate promotes, roller 2 can use 30 days continuously, and process stabilization, continuous film, substantially increase production yield.
