Description
Technical field
The utility model is related to a kind of belt feed template, the centering open-and-close mechanism of especially a kind of feed template.
Background technology
The centering open-and-close mechanism of belt feed template of the prior art is realized by the mechanism of gear and rack
Two folding baffles towards and away from mobile and keep centering.Figures 1 and 2 show that the centering of feed template in the prior art
The structure diagram of open-and-close mechanism, wherein 101 be folding baffle, 102 be adjustment plate, and 103 be rack, and 104 be clockwork spring, and 105 are
Around spring axis, 106 be clockwork spring frame, and 107 be gear, and 108 be baffle guide rod, and 109 be rack frame, and 110 be adjustment block, and 111 is adjust
Whole pull rod, 112 be conveying roll, and 113 be driving cylinder.
As depicted in figs. 1 and 2, the centralising device of pervious belt feed template is that have a tooth in adjustment plate medium design
Wheel, a pair of of rack of two pendant of gear connection, rack is connect by a pair of of rack frame with folding baffle, when outside pulling side folding baffle
When opening, band carry-over bar, gear, opposite side rack make opposite side folding baffle be moved toward opposite direction, realize both sides folding baffle
External-open and centering is kept simultaneously, to meet the conveying of wide material.Opposite action when being closed in pulling side folding baffle, drives
Rack, gear, opposite side rack, the movement of opposite side folding baffle realize that interior merging keeps centering to both sides folding baffle simultaneously, with
Meet the conveying of narrow material.When bar shaped sizing material material side is uneven, folding baffle can have micro at any time toward concession is opened, this function is
It is realized by a pair of of dish type clockwork spring.
The shortcomings that prior art is：
1st, centering adjustment trouble, due to being rack-driving, one tune is exactly a tooth when two side shields are about center line asymmetry
Away from still asymmetry will unclamp adjustment plate and be micro-adjusted.
2nd, micro folding is clockwork spring, and the material wide scope that clockwork spring is adapted to is smaller, generally between 100-580mm,
Engineering tire belt feed causes clockwork spring to fall short of or drawn dead (limit) state, does not have generally between 60-850mm at present
Fine motion function at any time, and when changing narrow sizing material, clockwork spring receipts are not gone back, and loosely influence feeding between two baffles.Separately
More using part in the prior art outside, cost is higher and quality weight.
Invention content
The purpose of this utility model is that it solves above-mentioned technical problem and a kind of easy to operate, simple in structure and effect is provided
The centering open-and-close mechanism of good feed template.
In order to solve the above-mentioned technical problem, the utility model adopts the following technical solution：
A kind of centering open-and-close mechanism of feed template is oriented to including two folding baffles, two guide rods, two brake cables
Wheel, brake cable and pull rod, two folding baffles can be slidably symmetrically mounted in feed template by two guide rods,
Two brake cable directive wheels are symmetrically mounted at the both sides of the roller supporting rack of feed template, and the brake string set is in two brake cables
A closed loop is formed between directive wheel, is respectively formed that there are two through-holes so that brake cable passes through on each folding baffle, each
The folding baffle is also affixed by a jackscrew and brake cable respectively, and two jackscrews are shifted to install at two brake cable directive wheel centers
The both sides of line, so that two folding baffles can be moved towards or be moved away from simultaneously, the pull rod passes through roller branch
Support and a folding baffle are affixed, are additionally provided with the first adjustment nut, second adjustment nut and compressed spring on the pull rod, and described
One adjusting nut is arranged on the outside of roller supporting rack, and the second adjustment nut is arranged on the inside of roller supporting rack, described
Compressed spring is sleeved on pull rod and the compressed spring is clamped in advance between second adjustment nut and roller supporting rack.
The beneficial effects of the utility model are：The design of the utility model makes structure significantly simple, reduces rack, rack
The manufacture cost of the components such as frame, gear, adjustment plate, clockwork spring frame is convenient in tune, and only need to unclamp brake cable jackscrew can be arbitrary
Adjustment, while mitigate feed template weight, also condition is created to a station multilayer (three layers or more).

Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description：
Referring to Fig. 3 and Fig. 4, the centering open-and-close mechanism of the feed template of the utility model includes two 1, two, folding baffles
2, two brake cable directive wheels 3 of guide rod, brake cable 4 and pull rod 5.
Two folding baffles 1 can be slidably symmetrically mounted in feed template by two guide rods 2, and two are opened
It closes baffle 1 and the installation of feed template belongs to the prior art, therefore wherein mounting structure details is no longer described in detail.
Two brake cable directive wheels 3 are symmetrically mounted at the both sides of the roller supporting rack 6 of feed template by connecting plate,
Multiple rollers are installed on roller supporting rack 6.The brake cable 4 forms a closed loop between being sleeved on two brake cable directive wheels 3, each
For through-hole 7 so that brake cable 4 passes through, each folding baffle 1 also passes through one respectively there are two being respectively formed on the folding baffle 1
Jackscrew 8 and brake cable 4 are affixed.Wherein, on a folding baffle 1 there are two through-hole 7, jackscrew 8 consolidates brake cable 4 in a through-hole
It lives calmly, another through-hole appoints brake cable 4 to pass through emptying.Since two jackscrews 8 are shifted to install in two 3 lines of centres of brake cable directive wheel
Both sides so that two folding baffles 1 can be moved towards or be moved away from simultaneously.In this way when the one of folding gear of pulling
For plate toward when opening, another piece of folding baffle is also automatic simultaneously toward movement is opened, and realizes automatic symmetrical folding.
The pull rod 5 is affixed across roller supporting rack 6 and a folding baffle 1, and the end of the pull rod 5 passes through a locking nut
12 is affixed with the outside of a folding baffle 1.The first adjustment nut 9, second adjustment nut 10 and pressure are additionally provided on the pull rod 5
Contracting spring 11, in order to ensure that structure is more stablized, the quantity of the first adjustment nut 9 and second adjustment nut 10 is two, institute
The outside that the first adjustment nut 9 is arranged on roller supporting rack 6 is stated, the second adjustment nut 10 is arranged on roller supporting rack 6
Inside, the compressed spring 11 is sleeved on pull rod 5 and the compressed spring 11 is clamped in second adjustment nut 10 and roller in advance
Between supporting rack 6.Adjustment material need to only adjust the first adjustment nut 9 and second adjustment nut 10 when wide, and the drawing of folding baffle is moved on to
Expect width position, it is easy to operate, while centering is easy to operate.It is sleeved on pull rod 5 with a compressed spring 11, so that it may realize micro-
Clockwork spring can not draw away when measuring the resistance of free-open-close, the free sensitive gearless rack of fine motion folding etc., while avoiding wide material, and material is too
Narrow clockwork spring receipts are not gone back, and influence the conveying of material.
In conclusion the content of the utility model is not limited in the above embodiments, those skilled in the art can
To propose other embodiments within the technological guidance's thought of the utility model, but these embodiments are included in this practicality newly
Within the scope of type.
