Technical field
The present invention relates to packaging field, especially with regard to a kind of pretreatment unit flattened before vacuum packaging bag seals.
Background technology
Vacuum bag is common food packaged type, finds in actual production, if the content of pack is when vacuumizing, the placement of its content does not flatten, then vacuumize final vacuum bag meeting local crowning, affect the aesthetic property of product external packaging.
Summary of the invention
In view of this, the present invention solves above-mentioned technical problem, it is provided that a kind of pretreatment unit flattened before vacuum packaging bag seals.
The purpose of the present invention is achieved through the following technical solutions:
A kind of pretreatment unit flattened before vacuum packaging bag sealing, the driven cotton-padded covering including frame, being arranged in frame and actively cotton-padded covering, for driving the motor of actively cotton-padded covering, regulating cylinders for regulating two of the driven cotton-padded covering spacing with actively cotton-padded covering.
Described frame includes that two pieces are provided with the side fixed block of corner and connect driven shaft and the driving shaft of dual-side fixed block, it is additionally provided with connecting rod between described two pieces of side fixed blocks, driven shaft is parallel to each other with driving shaft, described driven cotton-padded covering is rotatably mounted around on driven shaft, and described active cotton-padded covering is non-rotationally secured on driving shaft;One side end of described driving shaft is provided with teeth, and described motor is connected with driving shaft by chain, and chain engages each other with teeth, and the push rod of said two regulation cylinder is connected respectively with the both ends of driven shaft;It is equipped with driving shaft fixing hole on described two pieces of side fixed blocks and fixes elongated hole with driven shaft, described driving shaft fixing hole, driven shaft fix elongated hole and motor output end is on same straight line, described driven shaft fixes elongated hole and motor output end sets up separately in the both sides of driving shaft fixing hole, driving shaft is by bearing assembling nested with driving shaft fixing hole, and driven shaft fixes with driven shaft by bearing that elongated hole is nested to be assembled;The left and right sides of described driving shaft fixing hole is provided with dismountable Fixing shrink ring.
One frame, a driven cotton-padded covering, an active cotton-padded covering, a motor and one working group of two regulation cylinders compositions, the described pretreatment unit flattened before vacuum packaging bag seals includes at least one working group.
Preferably, the quantity of described working group is more than or equal to two.
The plurality of working group is arranged in parallel.
The present invention provides the benefit that compared to prior art:
After vacuum bagged enters food, first made pressing by the pretreatment unit flattened before vacuum packaging bag seals of the present invention and process, then to bag vacuum, can avoid vacuum bag that the serious protruding of local occurs, improve the aesthetic property of product external packaging.Vacuum bag before vacuumizing inserts the pretreatment unit flattened before vacuum packaging bag seals of the present invention, by adjusting regulation cylinder so that the spacing of driven cotton-padded covering and actively cotton-padded covering is in suitable distance, actively cotton-padded covering rotates under the driving of motor constantly, vacuum bag to be flattened is driven to be passed by the gap of driven cotton-padded covering and active cotton-padded covering, completing the pressing work before bag vacuum, the working (machining) efficiency of the pretreatment unit of the present invention is high and makes cost relatively low owing to structure is relatively easy.
Accompanying drawing explanation
The invention will be further described to utilize accompanying drawing, but the embodiment in accompanying drawing does not constitute any limitation of the invention.
Fig. 1 is the overall structure figure of the pretreatment unit flattened before vacuum packaging bag seals of the present invention.
Detailed description of the invention
The present invention is described in further detail below in conjunction with accompanying drawing and embodiment for the ease of it will be appreciated by those skilled in the art that.
Refer to Fig. 1, the embodiment of the present invention includes:
A kind of pretreatment unit flattened before vacuum packaging bag sealing, the driven cotton-padded covering 1 including frame 3, being arranged in frame 3 and actively cotton-padded covering 2, for driving the motor 4 of actively cotton-padded covering 2, regulating cylinders for regulating two of the driven cotton-padded covering 1 spacing with actively cotton-padded covering 2.
Frame 3 includes that two pieces are provided with the side fixed block of corner and connect driven shaft 31 and the driving shaft 32 of dual-side fixed block, it is additionally provided with connecting rod between two pieces of side fixed blocks, driven shaft 31 is parallel to each other with driving shaft 32, driven cotton-padded covering 1 is rotatably mounted around on driven shaft 31, and actively cotton-padded covering 2 is non-rotationally secured on driving shaft 32;One side end of driving shaft 32 is provided with teeth, and motor 4 is connected with driving shaft 32 by chain, and chain engages each other with teeth, and the push rod 51 of two regulation cylinders is connected respectively with the both ends of driven shaft 31;It is equipped with driving shaft fixing hole on two pieces of side fixed blocks and fixes elongated hole with driven shaft, driving shaft fixing hole, driven shaft fix elongated hole and motor output end is on same straight line, driven shaft fixes elongated hole and motor output end sets up separately in the both sides of driving shaft fixing hole, driving shaft is by bearing assembling nested with driving shaft fixing hole, and driven shaft fixes with driven shaft by bearing that elongated hole is nested to be assembled;The left and right sides of driving shaft fixing hole is provided with dismountable Fixing shrink ring.
3, driven cotton-padded covering of one frame 1, one actively 2, motor 4 of cotton-padded covering and one working group of two regulation cylinder compositions, the pretreatment unit flattened before vacuum packaging bag seals includes at least one working group.
Preferably, the quantity of working group is equal to two, and this Liang Ge working group is arranged in parallel, and the driven cotton-padded covering of first job group is more than the driven cotton-padded covering of second working group and the spacing of actively cotton-padded covering with the spacing of actively cotton-padded covering.
After vacuum bagged enters food, first made pressing by the pretreatment unit flattened before vacuum packaging bag seals of the present embodiment and process, then to bag vacuum, can avoid vacuum bag that the serious protruding of local occurs, improve the aesthetic property of product external packaging.Vacuum bag before vacuumizing inserts the pretreatment unit flattened before vacuum packaging bag seals of the present embodiment, by adjusting regulation cylinder so that the spacing of driven cotton-padded covering and actively cotton-padded covering is in suitable distance, actively cotton-padded covering rotates under the driving of motor constantly, vacuum bag to be flattened is driven to be passed by the gap of driven cotton-padded covering and active cotton-padded covering, completing the pressing work before bag vacuum, the working (machining) efficiency of the pretreatment unit of the present embodiment is high and makes cost relatively low owing to structure is relatively easy.
Finally should be noted that; above example explanation technical scheme; rather than limiting the scope of the invention; although having made to explain to the present invention with reference to preferred embodiment; it will be understood by those within the art that; technical scheme can be modified or equivalent, without deviating from the spirit and scope of technical solution of the present invention.
