Description
Technical field
The present invention relates to a kind of food automatic subpackaging equipment, especially to the equipment adopting packaging bag to carry out subpackage.
Background technology
The subpackage of food refers to and is filled in fractional pack so that selling by bulk or big packaged food.When fractional pack adopts the form of packaging bag (such as vacuum packaging bag), the packaging bag owing to processing is all in closure state, and the two side constituting bag fits together.For solid material (such as food such as prepared food class preserved dried beancurd, duck claw, chicken feet, preserved radish strips), in the process of automatization's subpackage processing, the bag mouth how automatically reliably to open the package, in order to carry out fill, the problem being always up being difficult to solve.Chinese utility model patent document CN203246616U discloses one " bag-feeding full-automatic vacuum packaging machine ", by pull bagging apparatus, drum bagging apparatus complete relevant work, pull bagging apparatus and adsorbed the two side of bag by two groups of suckers respectively, drive sucker to move again and rip bag mouth, then the air nozzle of drum bagging apparatus is probeed into and in bag, blast air.But its equipment is complicated, and action is complicated；And functional reliability has much room for improvement, breakage rate is bigger.Particularly when the above-mentioned prepared food based food of subpackage, the shape opened due to bag mouth is unfixing, unstable, and the liquid such as pouring process cannot be accomplished to be connected closely with hopper, the oil plant thick gravy comprised in food easily leak.So, in existing subpackage actual production, it is all adopt manual form to carry out.Its production efficiency is low, constitutes the bottleneck operation of automated production；Cost height enterprise adds enterprise and produces burden；It is big that Sterilized sanitation controls difficulty, and the safety of food can not get ensureing.
Summary of the invention
In order to solve above-mentioned drawback, the technical problem to be solved is to provide the bag mouth device for opening of a kind of packed food automatic packer, it is possible to the bag mouth automatically reliably opened the package.In order to solve above-mentioned technical problem, the technical solution used in the present invention is, the rolling type bag mouth device for opening of a kind of packed food automatic subpackaging, is provided with control system and controls each driving mechanism co-ordination, it is characterized in that, this device includes clamping device and spreading mechanism:
Described clamping device includes two clamping elements being correspondingly arranged, and described clamping element connects the first driving mechanism, drives linear reciprocating motion before and after at least one clamping element, switches clamping and unclamping in packaging bag two states；Two clamping elements are provided with by the material with bigger frictional force (such as rubber, especially silica gel.) two corresponding clamping work surfaces of constituting；Two clamping work surfaces clamp the middle part of two side of the close bag mouth of packaging bag；Described clamping element connects the second driving mechanism, drives at least one clamping element left and right straight reciprocating motion so that realize laterally opposed displacement between two clamping work surfaces；
Described spreading mechanism connects the 3rd driving mechanism and descends straight reciprocating motion on the whole；Spreading mechanism include two be correspondingly arranged strut element, each element that struts includes the hook of at least two test, and two hooks lay respectively at the position of both sides, corresponding described clamping work surface left and right；The described element that struts connects the 4th driving mechanism, drives at least one to strut linear reciprocating motion before and after element so that two strut the position relationship of element and switch in following A, B two states:
A. two corresponding hooks strutting element are drawn close mutually；
B. before and after two corresponding hooks strutting element separately.
Adopting technique scheme, described first, second, third, fourth driving mechanism can independently be arranged, as each operating mechanism or element connect electric magnet, motor or cylinder etc. respectively.Common drive mechanism can also realize corresponding actions by drive mechanism.Described frictional force is bigger to be meant that, clamps under state, and the frictional force of described clamping work surface and packaging bag lateral wall is more than the frictional force between packaging bag two medial wall.
First driving mechanism drive at least one clamping element backward/front rectilinear motion, two clamping elements clamp the middle part of the two side of the close bag mouth of packaging bag；Second driving mechanism drives at least one clamping element to left/right rectilinear motion, make to realize laterally opposed displacement between two clamping work surfaces, rubbing packaging bag two side relative sliding so that the bag mouth being positioned at clamping both sides, work surface left and right forms two openings being similar to almond shape；Then the 3rd driving mechanism drives spreading mechanism entirety to move down, and now two corresponding hooks strutting element are drawn close mutually, in the descending opening inserting two almond shapes respectively；Then the 4th driving mechanism drive at least one strut element backward/front rectilinear motion, make to separate before and after two corresponding hooks strutting element, simultaneously the first driving mechanism drives at least one clamping element to front/rear rectilinear motion, unclamp the clamping to packaging bag, four hooks are positioned at corner and pull open bag mouth, so as in stable tetragon, then the hopper insertion bag mouth of respective shapes can be carried out fill.Fill complete after packaging bag removed, second and third, four driving mechanisms drive relevant work elements reversely reset, carry out the work in next cycle.Such Automatic Cycle carries out.
From the foregoing, it will be observed that the beneficial effects of the present invention is, the bag mouth that this device can not only reliably open the package automatically, and the dimensionally stable that bag mouth is opened, it is connected tight with hopper；Its design is ingenious, and mechanism is simple, and action is succinct, efficient work, manufactures maintenance cost relatively low, it is easy to popularization and application；Improve production efficiency, reduce production cost, ensure food safety.
