Description
Technical field
The present invention relates to a kind of thumb wheel covers drop-head, especially a kind of thumb wheel set drop-head automatically covering contracting equipment for casing.
Background technology
Must be using the casing after set contracting on the high speed sausage filler of automatization.The enterprise of traditional-handwork fill sausage is by people
Work is cut off the sausage casing of reel on enema tube and after manual compression, after artificial casing quilt cover is condensed to every more than ten meters of short tube
Personnel labor intensity can greatly be mitigated.The casing of set contracting requires the screw-like compression in rule, and the finished product of set contracting requires to the greatest extent
Amount is compact, and it is impossible to there be the situation of section of decoherencing, open, the thread pitch of formation requires to try one's best and grows, and the casing that every set contracts out will be in
Straight line, to facilitate the insertion of coloclysis bar；The endoporus of the finished product after set contracting has certain requirement it is necessary to coordinate the size of coloclysis bar.
Especially undersized casing, set contracting endoporus requirement is as far as possible larger, and the coloclysis bar of convenient insertion has bigger fill endoporus.?
This, decoherence, open section and refer respectively to finished product casing pipe and scatter in the vertical because screw thread is not compacted, and finished product casing pipe by
Twistlock is not had firmly to dissipate into some trifle casing pipes in individual threads.Both of these case all can lead to casing pipe singlehanded
Hold on the coloclysis bar being enclosed within enema, therefore become substandard product.
Traditional set shrinking structure includes two types：One class is the mode with inner thread head, and casing is fed into a spiral shell
In larger nut shape set drop-head, the female thread that this nut shape covers drop-head forms screw thread and by covering drop-head rotation on casing
Turn, the lead angle by thread promotes casing compressing to fold.
Also have a class by the way of plectrum or thumb wheel, vertically put down at one around the inflation casing feeding in the horizontal direction
It is uniformly distributed three to four thumb wheels centered on the heart of casing section hole on face, plectrum is respectively arranged with each thumb wheel or has helical teeth
Groove, these thumb wheels surround the circular hole less than casing bore, plectrum or peak wedging casing certain depth jointly, and each two is adjacent
The plectrum of thumb wheel or teeth groove be in step-like connecting by some planes or curved surface.When the outside synchronous axial system of thumb wheel group, plectrum or
Thumb wheel tooth on casing is formed a thread like folding and to casing produce promote compression.
The set shrinking structure of relatively both types understands, the advantage of inner screw sheath drop-head is, can be formed on casing
The more uniform threaded exterior of ratio, can cover the casing of minification.The shortcoming of inner screw sheath drop-head then includes：When set drop-head screw thread
Eat the depth such as less than 0.5mm of casing when endoporus is excessive, easily skid it is impossible to set contracts on material；As covered drop-head screw thread
Endoporus is slightly smaller, easily encounters the set contracting bar within casing, scratches casing；As changed less set contracting bar, the finished product endoporus of formation is inclined
Little, do not meet the requirement of coloclysis manufacturing enterprise；If the bore of raw material casing changes, effective screw thread can cannot be formed, from
And lead to cover the interruption of contracting；If the set contracting speed requiring is too high, rotating thread head can be because of the high heating of rotating speed, thus cannot cover
Contracting.This set the requirement to casing material bore for the shrinking structure higher it is impossible to reach higher set contracting speed of production.
By contrast, the advantage using the set drop-head of plectrum or thumb wheel is, such set shrinking structure is interior than aforementioned
Thread bush drop-head can allow that casing bore has bigger variable quantity, bigger to the thrust of casing collapsible, can reach higher
Sausage casing contracting speed.But, the set drop-head shortcoming using plectrum or thumb wheel is, because the plectrum on two adjacent wheels or tooth
Groove fails to engage the ridge for smoothing, and therefore can not form well-proportioned spiral lamination on casing, not only impact set contracting casing
The outward appearance of product, also has certain impact in casing fill sausage.In addition, the set drop-head of existing plectrum or thumb wheel cannot be to relatively
Small-bore casing carries out set contracting, casing below 16 millimeters for the such as diameter.
Generally, casing has certain retractility, and after casing inflation, under conditions of intrinsic pressure difference, casing bore is also different.?
Herein, casing diameter then refers to measure the semi-perimeter as casing for the flat width of casing under casing unaerated state, then
The theoretical diameter of the unexpanded front casing being calculated with pi.Below using casing diameter and this two arts of casing bore
During language, their implication can be distinguished.
In addition, under traditional approach, each thumb wheel or plectrum using the set drop-head of plectrum or thumb wheel can be in casing to shapes
Become screw thread, but screw thread is simultaneously discontinuous.In other words, the plectrum under traditional approach or thumb wheel simply formed on casing a series of discontinuously
Screw thread.
Content of the invention
The defect existing for prior art, the technical problem to be solved is to provide a kind of new thumb wheel set
Drop-head, can reach some advantages of inner screw sheath drop-head in the advantage keeping original thumb wheel set drop-head.
This technical problem covers drop-head by a kind of thumb wheel of the present invention and solves, and this thumb wheel set drop-head is used for being enclosed within
The casing pipe with tight thread structure is shortened on set contracting bar and along described set contracting bar feed, inflation cylindric sausage casing,
Described thumb wheel set drop-head include multiple around the described set equally distributed thumb wheel of contracting bar, the rotation axiss of all described thumb wheels are arranged
In an at a common plane perpendicular to casing direction of feed, described thumb wheel is designed to be suitable around the described rotary shaft of itself
The endoporus jointly surrounding around described thumb wheel while rotation to described casing direction of feed to line locking does planetary rotation, wherein,
Each described thumb wheel has equally distributed some thumb wheel teeth on the outer periphery, and each described thumb wheel tooth has positioned at outer radial periphery
Crest top land, be located at described thumb wheel tooth both side ends side end face, between two described side end faces towards thumb wheel circumference rotation side
To tooth front and two described side end faces between back to thumb wheel circumference direction of rotation rear flank, by described tooth front and
Described crest top land intersects and forms tooth top forward position, and the described tooth top forward position of the thumb wheel tooth of each described thumb wheel is configured to be suitable to squeeze
Enter to make in the space of casing casing to form threaded line, wherein, the tooth top forward position of the thumb wheel tooth of the adjacent described thumb wheel of each two
Form continuous threaded line when connecting, and, the tooth front of the thumb wheel tooth of each described thumb wheel is revolved in the circumference of described thumb wheel
Turn and turn forward on direction.Because all thumb wheels are also common around all thumb wheels while synchronously rotating to casing direction of feed
The endoporus surrounding does planetary rotation, thus can obtain the effect of approximate inner screw sheath drop-head operation principle, to casing during set contracting
The screw thread of upper formation produces the power of a twistlock, and sausage casing can be allowed to be not easy to decoherence after contracting, open section.Continuously the leading to of threaded line
The casing pipe better quality being formed, evenly closely.Leaning forward of thumb wheel tooth enables thumb wheel tooth to enter inflation with more preferable angle
Cylindrical shape casing.
Thumb wheel according to the present invention covers a kind of preferred implementing form of drop-head, and described tooth front and described rear flank are all no
The continuous curve surface of knuckle, and the tooth top forward position phase in the thumb wheel tooth of the adjacent described thumb wheel of each two is connected into continuous threaded line
When, the tooth front also smoothly transition ground linking of this two described thumb wheel teeth.
Thumb wheel according to the present invention covers a kind of preferred implementing form of drop-head, and the described rear flank of described thumb wheel tooth is with fillet
It is transitioned into described crest top land.Casing is to enter in thumb wheel set drop-head mechanism in the state of fully aerated, and works as casing and be folded
Require each layer compression must try one's best closely during compression, thus air will have been avoided to be compressed between two-layer in compression.If
Two interlayers have air, when the casing after covering drop-head is compressed further by the follow-up mechanism of equipment, can cause this part
Air is pressed against the casing screw thread outer that set has contracted, thus destroying the outward appearance of casing, this partial air also can squeeze casing sometimes
Go out holes, become defective work.Round-corner transition between the rear flank of thumb wheel and crest top land can make thumb wheel tooth when leaving casing
The air that more easily two-layer can be folded between casing is extruded to interior to casing direction of feed from outer along screw thread.
Cover a kind of preferred implementing form of drop-head according to the thumb wheel of the present invention, two described side end faces of described thumb wheel tooth with
Two intersection points in described crest top land and described tooth front form first crown and second crown respectively, wherein, described
First crown has position more forwardly of in described thumb wheel circumference direction of rotation than described second crown.That is, dialling
The gear teeth turn forward more than at the second crown along described thumb wheel circumference direction of rotation at the first crown.Such arrangement
Ratio remains the easily processing of same angle of inclination at the first crown and the second crown, because the latter needs with same in high precision
When control the feed of horizontal direction of Digit Control Machine Tool and the rotation of the workpiece hand of spiral, processing cost is higher.
Thumb wheel according to the present invention covers a kind of preferred implementing form of drop-head, and described thumb wheel tooth is in place of described first crown
With respect to thumb wheel circumference formed tine angle between 105-135 degree, such that it is able to tooth front incision inflation be circle
Form apparent screw thread during the casing of tubular.Above-mentioned tine angle refer to through this crown, perpendicular to thumb wheel rotation axiss
Section the angle in thumb wheel tooth with the intersection of tooth front and thumb wheel circumference respectively.
Thumb wheel according to the present invention covers a kind of preferred implementing form of drop-head, the diameter of described thumb wheel and the chi of casing diameter

Times, operationally, the rear flank of previous thumb wheel tooth does not also leave casing to two adjacent thumb wheel teeth of thumb wheel, dials for latter one
The crown in the tooth front of the gear teeth has been cut into the casing inflated, and this can cause air to be enclosed in this layer of casing screw thread, thus no
Method set contracting or set contracting effect on driving birds is not good.Conversely, because the casing pitch of the casing of contracting to be covered determines the space width of thumb wheel tooth, because
And if the diameter of thumb wheel is less than 4.37 times of casing diameter, then the thumb wheel number of teeth mesh that can design on each thumb wheel can be less,
Thumb wheel tooth can be excessively sparse, thus bringing a series of problem for the design of thumb wheel.
Thumb wheel according to the present invention covers a kind of preferred implementing form of drop-head, and the thumb wheel tooth pitch of described thumb wheel is casing diameter
1.78 to 1.9 times, form larger pitch such that it is able to cut when inflation is cylindric casing in tooth.Here, institute
State thumb wheel tooth pitch to refer on adjacent thumb wheel tooth along the circumferential distance between same position.Here, thumb wheel tooth pitch and casing diameter it
Between multiple proportion determined by concrete production requirement.Casing for specific dimensions it is readily appreciated that, thumb wheel tooth pitch is proportional to
Casing pitch, thus it is proportional to casing diameter.Due to the restriction of the original bore of casing, the external diameter of the casing pipe after set contracting can't
Bore beyond the casing after inflation is too many, and the casing pipe due to requiring to cover after contracting can easily be set to the coloclysis of enema
On bar, the internal diameter minima of the casing pipe therefore after set contracting is then limited by coloclysis bar size again, should have more than the latter's
Size.
Cover a kind of preferred implementing form of drop-head according to the thumb wheel of the present invention, the adjacent thumb wheel tooth on each described thumb wheel it
Between the top of groove that formed see that there is bigger width than this channel bottom along thumb wheel circumferencial direction.So, between thumb wheel tooth
Groove be just processed as shape wide at the top and narrow at the bottom.The teeth groove sideline of two adjacent thumb wheels connects up and down.

Specific embodiment
Fig. 1 is shown according to the present invention, the set drop-head 10 of the thumb wheel with four thumb wheels in the form of axonometric chart.This thumb wheel
The main building block of set drop-head includes：Active thumb wheel bevel gear 1, active shaft bevel gears 2, end cap 3, thumb wheel seat 4, thumb wheel 5,
Thumb wheel fixing axle 6, axle top cover 7, gear positioning sleeve 8 and driven wheel of differential 9.In conjunction with the annexation of Fig. 1 each several part easy to understand,
Will not be described here.
This thumb wheel covers drop-head 10 and is used for being enclosed within contracting bar 11 and covers cylindrical shape that contracting bar 11 feeds, inflation along described
12 sets of casing shortens the casing pipe with tight thread structure into.This four thumb wheels are uniformly distributed around set contracting bar 11, and its rotation
Axis is arranged in an at a common plane perpendicular to casing direction of feed, and described thumb wheel is designed to be suitable around the rotation of itself
The endoporus that shaft axis surround jointly around described thumb wheel while synchronously rotation to described casing direction of feed does planetary rotation, its
In, each described thumb wheel has equally distributed thumb wheel tooth 13 on the outer periphery, and each described thumb wheel tooth 13 has outside positioned at footpath
Week crest top land 14, be located at described thumb wheel tooth both side ends side end face 15, between two described side end faces 15 towards thumb wheel
Back to the rear flank of thumb wheel circumference direction of rotation between the tooth front 16 of circumference direction of rotation and two described side end faces 15
17, intersected and formed tooth top forward position 18 by described tooth front 16 and described crest top land 14, the thumb wheel tooth 13 of each described thumb wheel
Casing 12 is made to form threaded line, wherein, each two in the space that described tooth top forward position 18 is configured to be suitable to clamp-on casing 12
The tooth top forward position 18 of the thumb wheel tooth 13 of adjacent described thumb wheel forms continuous threaded line when connecting, and, each described group
The tooth front 16 of the thumb wheel tooth 13 of wheel turns forward in the circumference direction of rotation of described thumb wheel.Because all thumb wheels are synchronously
Also the endoporus jointly surrounding around all thumb wheels while rotation to casing direction of feed does planetary rotation, thus can obtain approximate
The effect of inner screw sheath drop-head operation principle, produces the power of a twistlock, Ke Yirang to the screw thread being formed on casing 12 during set contracting
It is not easy to decoherence after 12 sets of contractings of casing, open section.The casing pipe better quality continuously resulting in of threaded line, evenly closely.
Leaning forward of thumb wheel tooth 13 enables thumb wheel tooth 13 to enter the cylindrical shape casing of inflation with more preferable angle.
As shown in fig. 6, described tooth front 16 and described rear flank 17 are all the continuous curve surfaces of no knuckle, and in each two
When the tooth top forward position 18 of the thumb wheel tooth 13 of adjacent described thumb wheel is mutually connected into continuous threaded line, this two described thumb wheel teeth 13
Tooth front 16 also smoothly transition ground linking.
As shown in Figures 3 to 5, the described rear flank 17 of described thumb wheel tooth 13 with round-corner transition to described crest top land 14.Intestinal
Clothing 12 is to enter in thumb wheel set drop-head mechanism in the state of fully aerated, and requires each layer when casing 12 is folded compression
Compress and must try one's best closely, thus air will have been avoided to be compressed between two-layer in compression.If two interlayers have air,
When casing after covering drop-head is compressed further by the follow-up mechanism of equipment, the air of this part can be caused to be pressed against what set had contracted
Casing screw thread outer, thus destroying the outward appearance of casing, this partial air also can extrude holes casing 12 sometimes, become and do not conform to
Lattice product.Round-corner transition between the rear flank 17 of thumb wheel and crest top land 14 can enable thumb wheel tooth 13 more hold when leaving casing 12
The air folding two-layer between casing of changing places is extruded to interior to casing direction of feed from outer along screw thread.
As shown in fig. 6, two described side end faces 15 of described thumb wheel tooth 13 and described crest top land 14 and described tooth front 16
Two intersection points form first crown 19 and second crown 20 respectively, wherein, described first crown 19 is than described
Two crowns 20 have position more forwardly of in described thumb wheel circumference direction of rotation.That is, thumb wheel tooth 13 is in the first tooth
Turn forward more than at the second crown 20 along described thumb wheel circumference direction of rotation at point 19.Such arrangement compares first
Remain at crown 19 and the second crown 20 that same angle of inclination is easier to process, because the latter needs with the same time control of high accuracy
The feed of the horizontal direction of Digit Control Machine Tool processed and the rotation of the workpiece hand of spiral, processing cost is higher.
As shown in figure 5, the crown that described thumb wheel tooth 13 is formed with respect to thumb wheel circumference in place of described first crown 19 inclines
Angle θ is between 105-135 degree, apparent such that it is able to be formed when cutting, in tooth front, the casing 12 that inflation is cylindrical shape
Screw thread.Above-mentioned tine angle θ refer to through this crown, section perpendicular to thumb wheel rotation axiss respectively with tooth front and dial
Angle in thumb wheel tooth for the intersection of wheel circumference.
As shown in figure 3, cover a kind of preferred implementing form of drop-head according to the thumb wheel of the present invention, the diameter D of described thumb wheel with
The dimension scale of casing diameter is designed to so that the crown in the tooth front of a rear thumb wheel tooth 13 is in previous thumb wheel tooth 13
Rear flank 17 just can clamp-on casing after leaving casing.Preferably, the diameter D of described thumb wheel be casing diameter 4.37 to
5.88 again.If greater than 5.88 times, two adjacent thumb wheel teeth 13 of thumb wheel operationally, the rear flank of previous thumb wheel tooth 13
17 also do not leave casing, and the crown in the tooth front of a rear thumb wheel tooth 13 has been cut into the casing inflated, and this can cause air
It is enclosed in this layer of casing screw thread, thus contracting or set contracting effect on driving birds is not good cannot be covered.Conversely, because the casing of the casing of contracting to be covered
Pitch determines the space width of thumb wheel tooth 13, thus if the diameter D of thumb wheel is less than 4.37 times of casing diameter, then each thumb wheel
On the thumb wheel number of teeth mesh that can design can be less, thumb wheel tooth can be excessively sparse, thus bringing a series of asking for the design of thumb wheel
Topic.
As shown in figure 5, the thumb wheel tooth pitch d of described thumb wheel is 1.78 to 1.9 times of casing diameter, such that it is able to cut in tooth
Entering inflation is to form larger pitch during cylindric casing.Here, described thumb wheel tooth pitch d refers on adjacent thumb wheel tooth 13
Along the circumferential distance between same position.Here, the multiple proportion between thumb wheel tooth pitch d and casing diameter is will by concrete production
Ask decision.Casing for specific dimensions it is readily appreciated that, thumb wheel tooth pitch is proportional to casing pitch, thus it is straight to be proportional to casing
Footpath.Due to the restriction of the original bore of casing, the external diameter of the casing pipe after set contracting can't be beyond the bore of the casing 12 after inflation
Too much, the casing and due to requiring the casing pipe after set contracting can easily be set on the coloclysis bar of enema, therefore after set contracting
The internal diameter minima of pipe is then limited by coloclysis bar size again, should have the size more than the latter.
As shown in fig. 6, the top of the groove being formed between adjacent thumb wheel tooth 13 on each described thumb wheel is than this trench bottom
Portion sees there is bigger width along thumb wheel circumferencial direction.So, the groove between thumb wheel tooth 13 is just processed as shape wide at the top and narrow at the bottom
Shape.The teeth groove sideline of two adjacent thumb wheels connects up and down.
As shown in fig. 6, the side end face 15 of the thumb wheel tooth 13 of described thumb wheel is constructed in a kind of intilted mode so that phase
The side end face 15 smoothly transition ground of the thumb wheel tooth 13 of adjacent described thumb wheel engages.
The surfacing that thumb wheel covers drop-head is smooth food grade materials, preferably Teflon, polyurethane, polyamide
(PA), polyether-ether-ketone (PEEK) etc..These materials have favorable lubricating property and wearability.
It is obvious also possible to design has the thumb wheel set drop-head of different number of thumb wheel, although inventors believe that four are dialled
Wheel is preferred technical scheme, because three thumb wheels can make continuous screw thread be difficult to be formed, and the thumb wheel of more than five then can increase
The complexity of adding system.
More than describe the preferred embodiments of the present invention, but the spirit and scope of the present invention be not limited to disclosed herein
Particular content.Those skilled in the art can make more embodiments and application according to the teachings of the present invention, and these are real
Apply mode and application would be within the spirit and scope of the present invention.The spirit and scope of the present invention not limited by specific embodiment,
