Side seal mechanism
Technical field
The utility model relates to the packaging for foodstuff field, particularly relates to the side seal mechanism that is applied in full-automatic vacuum packaging machine.
Background technology
Vacuum packaging also claims the decompression packing, all to extract the air in packing container out sealing, maintain in bag in the height decompression state, air starvation is equivalent to the hypoxemia effect, make germ there is no life condition, to reach fresh, the anosis rotten purpose occurred of fruit, so be vacuum-packed in widespread use in food service industry.In the vacuum packaging process, need to carry out side seal to packaging bag before vacuumizing, side seal refers to involution is carried out in the packaging bag both sides, traditional method is by artificial side seal, but artificial side seal labor intensive, production efficiency on the one hand is low, artificial side seal sealing effectiveness is bad on the other hand, can not guarantee its vacuum effectiveness, and easily air inlet is made moist.
The utility model content
For artificial side seal labor intensive, production efficiency is low and sealing effectiveness is bad problem, the utility model provides a kind of side seal mechanism of realizing automatic side-sealing.
Technical solution adopted in the utility model is: side seal mechanism comprises actuating device, guide rail, traversing carriage, lateral seal and traction chuck; Traversing carriage is erected on guide rail and by actuating device and drives traversing carriage to be moved on guide rail, and lateral seal and traction chuck are oppositely arranged on the traversing carriage upper end, lateral seal encapsulation packing, and traction chuck pulls feeding.
In technique scheme, there is certain distance between lateral seal and traction chuck, the length that this distance is packaging bag, give the space of side seal and a buffering of feeding.
In technique scheme, actuating device comprises motor and leading screw, and motor drives leading screw to rotate, and leading screw connects traversing carriage.
In technique scheme, lateral seal comprises heat block and the first cylinder, two opposed settings of heat block by the first air cylinder driven clamping with open.
In technique scheme, traction chuck is by the second air cylinder driven clamping and open.
The beneficial effects of the utility model are: the side seal mechanism of above-mentioned structure, can automatic feeding and add heat-seal, and do not need artificial encapsulation, save manpower; Provide running power by motor and cylinder, running is smooth, and production efficiency is high; The power operation sealing, good sealing effect, guarantee airtight quality.

In figure, 1, actuating device; 11, motor; 12, leading screw; 2, guide rail; 3, traversing carriage; 4, lateral seal; 41, heat block; 42, the first cylinder; 5, traction chuck; 51, the second cylinder.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 has schematically shown the side seal mechanism according to a kind of embodiment of the present utility model.
Side seal mechanism, comprise actuating device 1, guide rail 2, traversing carriage 3, lateral seal 4 and traction chuck 5; Traversing carriage 3 is erected on guide rail 2 and by actuating device 1 and drives traversing carriage 3 to be moved on guide rail 2, lateral seal 4 and traction chuck 5 are oppositely arranged on traversing carriage 3 upper ends, the working position of the working position of lateral seal 4 and traction chuck 5 is on same straight line, lateral seal 4 encapsulation packings, traction chuck 5 pulls feeding; Have certain distance between lateral seal 4 and traction chuck 5, the length that this distance is packaging bag, give the space of side seal and a buffering of feeding.
Actuating device 1 comprises motor 11 and leading screw 12, and motor 11 drives leading screw 12 to rotate, and leading screw 12 connects traversing carriage 3 lower ends, and the sense of motion of leading screw 12 and the moving direction of packaging bag parallel.
Lateral seal 4 comprises heat block 41 and 42, two opposed settings of heat block 41 of the first cylinder and drives clamping and open, the mouth that heat block 41 installs at the first cylinder 42 by the first cylinder 42.
Traction chuck 5 is driven clamping and is opened by the second cylinder 51, and the second cylinder 51 is parallel cylinder, and traction chuck 5 is located under the mouth of parallel cylinder lower end.
Workflow of the present utility model is: 1, the packaging bag bar enters to expect between lateral seal 4 and traction chuck 5, and traction chuck 5 clamps the packaging bag bar, and lateral seal 4 clampings are simultaneously sealed packaging bag one side; 2, actuating device 1 drives traversing carriage 3 to move backward on guide rail 2, and traction chuck 5 drives packaging bag bar integral body and moves backward; 3, after pack bar integral body moves the distance of a packaging bag backward, traction chuck 5 and lateral seal 4 unclamp the packaging bag bar, and then actuating device 1 drives traversing carriage 3 to move forward on guide rail 2 again, then repeating step 1 and step 2.
Above embodiment just is explanation rather than restriction the utility model, and the equivalence of doing according to the described method of the utility model patent claim therefore all changes or modifies, and is included in the utility model patent claim.
