Description
Technical field
The utility model relates to a kind of label providing apparatus heat shrink films fast shut-off device, relates in particular to a kind of fast shut-off device of heat shrink films label providing apparatus.
Background technology
Label providing apparatus pulls down heat shrink films and send, and by a center guide pillar, it is cylindric that heat shrink films is supported into, is cut out the Membrane cover of Len req again by shutoff device, to be enclosed within on the bottle, to carry out thermal contraction then and is positioned on the bottle.
The cutting knife of present shutoff device must revolve three-sixth turn, just can finish once to go out cutter and return sword action.But have at least 180 degree scopes to belong to useless stroke in this cutting knife actuating length, that is to say that cutting knife revolves in the three-sixth turn stroke at every turn, be merely able to cut out the thermal contraction Membrane cover of a unit, so that can't increase substantially the work speed that cuts off heat shrink films, the productive output of influence cover label.
The utility model designer has proposed the patent case No. 90205298, as shown in Figure 1, 2, 3, its shutoff device is established several cutting knife groups with equidistant angle ring on the fixed frame 13 of center guide pillar 10 peripheries, these cutting knife groups are radially two of hub settings first and second rotating shaft 11,12 of being separated by all, first rotating shaft 11 of one of them cutting knife group is provided with a power wheel 113, turns to accept extraneous transmission device.Default following eccentric rod 112 in each first rotating shaft, 11 bottom is assigned in the relative opening of a transmission ring flat-plate 14 with pivot, makes each first rotating shaft 11 carry out equidirectional rotation.
And these first and second rotating shaft 11,12 tops all are provided with a upward eccentric rod 111,121, and respectively organize two and go up connecting rods 15 of pivot joint between the eccentric rod 111,121, carry out swing to drive each second rotating shaft 12 and bottom cutting knife 16 thereof.The centre distance B1 of above-mentioned first and second rotating shaft 11,12 is slightly larger than two centre distance B2 that go up eccentric rods 111,121, make first rotating shaft 11 at folk prescription in rotation, about driving second rotating shaft 12 and cutting knife 16 relatively and carrying out back and forth swing go out cutter and return sword.
This shutoff device really can improve the work speed that heat shrink films cut off and overlapped label, but it must be provided with 11,12 and six connecting rods 15 of six groups of first and second rotating shafts, so that integrated member is comparatively complicated, increases and makes stack-mounted cost and man-hour.
The utility model content
In order to overcome above-mentioned defective, the purpose of this utility model is to provide a kind of label providing apparatus heat shrink films fast shut-off device, it can further simplify integrated member except improving heat shrink films cut-out and cover label work speed, reduce and make assembly cost and man-hour.
For achieving the above object, shutoff device of the present utility model is established several cutting knife groups with equidistant angle ring on the fixed frame of label providing apparatus center guide pillar periphery, one of them cutting knife group radially two of hub settings be separated by first, two rotating shafts, be provided with a power wheel in first rotating shaft, turn to accept extraneous transmission device, this group first, the eccentric rod on two rotating shaft tops articulates a connecting rod between the two, and first, the centre distance of two rotating shafts is slightly larger than the centre distance of two eccentric rods, make first rotating shaft at folk prescription in rotation, about driving second rotating shaft and bottom cutting knife thereof relatively and carrying out back and forth swing go out cutter and return sword; It is characterized in that, have only one of them cutting knife group to have first and second rotating shaft in above-mentioned whole cutting knife group, and remaining cutting knife group has only second rotating shaft, and all the eccentric rod on the cutting knife group second rotating shaft tops then pivot be assigned in the relative opening of a transmission ring flat-plate, make whole second rotating shafts carry out equidirectional reciprocal rotation.
In sum, the utility model shutoff device respectively is made as one group with first rotating shaft and connecting rod quantity, and simplifies integrated member, reduces and makes assembly cost and man-hour, and have higher cut-off velocity, has industrial value.

The specific embodiment
Following conjunction with figs., and describe the structure and the characteristics of shutoff device of the present utility model in detail with embodiment.
At first, shown in Fig. 4,5, shutoff device of the present utility model is provided with fixed frame 20 in center guide pillar 10 peripheries of label providing apparatus equally, and establishes several cutting knife groups with equidistant angle ring on the fixed frame 20.Radially two of hub settings first and second rotating shaft 30,40 of being separated by of one of them cutting knife group, remaining cutting knife group then only has second rotating shaft 40.First rotating shaft 30 of this one of them cutting knife group is provided with a power wheel 34, turns by belt 35 to accept extraneous transmission device electrical motor.
Shown in Fig. 4,5,6, all the eccentric rod 41,410 of different angles is all extended on second rotating shaft, 40 tops of cutting knife groups, is assigned in the relative opening of a transmission ring flat-plate 60 with pivot, makes whole second rotating shafts 40 can synchronously equidirectional reciprocal rotation.The Cutter apron 71 of these second rotating shaft, 40 then winding concentric of bottom is for the cutting knife 70 that can adjust outreach is installed.
First and second rotating shaft 30,40 tops of this one of them cutting knife group respectively have an eccentric rod 31,41, and two eccentric rods 31,41 of this group are made as identical eccentric direction, further between two eccentric rods 31,41, articulate a connecting rod 50, make first rotating shaft 30 via eccentric rod 31,41, connecting rod 50 and transmission ring flat-plate 60, to drive each second rotating shaft 40 and cutting knife 70 swings go out cutter.
In preferred embodiment, the last hypomere of first and second rotating shaft 30,40 passes through bearing 32,42 respectively with last lower carrier plate 21,22 relative openings of hub setting in fixed frame 20, and second rotating shaft, 40 end faces baffle ring 45 of screw 46 interlockings.In addition, install bearing 33,43 additional between eccentric rod 31,41 epimeres of first and second rotating shaft 30,40 of a cutting knife group therein and the connecting rod 50, and cooperate location metal (upper seat 51.And these eccentric rod 41 hypomeres and all the other eccentric rods 410 adopt bearing 44 pivots to be assigned in transmission ring flat-plate 60, and cooperate location metal (upper seat 61.
The centre distance B1 of present embodiment first rotating shaft 30 and one of them second rotating shaft 40 is slightly larger than the centre distance B2 of two eccentric rods 31,41, therefore first rotating shaft 30 is revolved when turning around at every turn, this second rotating shaft 40 can only left and right sides reciprocally swinging once, and its pendulum angle is only spent near 180, and shown in its operating principle No. 90205298 patent case as shown in Figure 1, 2, 3.
When extraneous transmission device is spent by belt 35 drive first rotating shafts 30 and power wheel 34 Rotate 180s thereof, swing to drive one of them second rotating shaft 40 and eccentric rod 41 thereof via eccentric rod 31, connecting rod 50 relatively, utilize transmission ring flat-plate 60 synchronous interlock all the other second rotating shaft 40 and eccentric rods 410 simultaneously, make whole second rotating shafts 40 and cutting knife 70 swings near 180 degree, finish once go out cutter, the action of returning sword.When 30 Rotate 180s of equidirectional again drive first rotating shaft of transmission device belt 35 are by the time spent, promptly drive whole second rotating shafts 40 and cutting knife 70 reverse swings answers, and finish out cutter again, the action of returning sword.
