BACKGROUNDIn daily life, the importance of foods to the people is self-evident, but when foods are exposed to the air, they can easily spoil due to the action of moisture or bacteria. Thus, not only a serious waste of foods can be caused but also the bad foods are harmful to human. In order to more conveniently keep food fresh, people have developed vacuum packaging machines by utilization of the vacuum preservation principle for the vacuum package of foods, so that the shelf life of foods can be prolonged.
An external pumping vacuum packaging machine requires a worker to flatten mouths of bags to be packaged by hands in the vacuum-pumping plastic package process, so that the mouths of the bags to be packaged can become flat when a plastic seal presses down. But the operation method, on one hand, requires the operation of the workers and hence wastes manpower, and on the other hand, tends to lead to fold, leakage and other defects and hence has low success ratio of plastic package. Meanwhile, the operation mode imposes high requirement on the worker, and the worker needs to flatten the mouth of the bag to be packaged and operates a control panel at the same time, so that the rate of industrial accidents or poor plastic package may be increased.

An embodiment of the present disclosure provides an external pumping vacuum packaging machine 10. As illustrated in
For instance, as shown in
First method: the first clamping device 13 does not move, and the tightening device 15 only drives the second clamping device 14 to move towards the direction away from the first clamping device 13.
Second method: the second clamping device 14 does not move, and the tightening device 15 only drives the first clamping device 13 to move towards the direction away from the second clamping device 14.
Third method: the tightening device 15 drives the first clamping device 13 and the second clamping device 14 to move towards opposite directions respectively, namely driving the first clamping device 13 to move towards the direction away from the second clamping device 14 and driving the second clamping device 14 to move towards the direction away from the first clamping device 13.
All the three methods can increase the spacing between the first clamping device 13 and the second clamping device 14, so as to tighten the bag mouth of the bag to be packaged. No limitation will be given here to the methods in the embodiment of the present disclosure.
For instance, the external pumping vacuum packaging machine provided by the embodiment of the present disclosure adopts the first clamping device and the second clamping device to respectively clamp both ends of the bag mouth of the bag to be packaged by arrangement of the first clamping device and the second clamping device, and subsequently, adopts the tightening device to drive the first clamping device and/or the second clamping device to move to tighten the bag mouth of the bag to be packaged, so as to achieve automatic flattening of the bag mouth of the bag to be packaged. Because no worker is required to manually flatten the bag mouth of the bag to be packaged, the manpower can be saved, and meanwhile, the incidence rate of industrial accidents can be reduced and the success ratio of plastic package can be improved.
For instance, as shown in
For instance, the tightening device 15 drives the first clamping device 13 and the second clamping device 14 to move oppositely along the direction of the connecting line of both ends of the bag mouth of the bag to be packaged, so that the bag mouth of the bag to be packaged can be more easily flattened, which is favorable for the subsequent sealing operation.
For instance, as illustrated in
For instance, as illustrated in
For instance, the specific shapes of the first upper clamp plate 131, the first lower clamp plate 132, the second upper clamp plate 141 and the second lower clamp plate 142 may be various, e.g., may be a rectangular strip, a plate or a column. No limitation will be given on the shapes here in the embodiment of the present disclosure.
For instance, both the tightening device 15 and the driving device 16 may adopt a plurality of driving modes, e.g., may adopt gear transmission or threaded transmission. No limitation will be given on the driving modes here in the embodiment of the present disclosure.
For instance, as illustrated in
For instance, as shown in
It should be noted that the clamping force of the first clamping device 13 may be implemented by the spacing between the first upper clamp plate 131 and the first lower clamp plate 132, and the clamping force is larger when the spacing between the first upper clamp plate and the first lower clamp plate is smaller. Similarly, the clamping force of the second clamping device 14 may be also implemented by the spacing between the second upper clamp plate 141 and the second lower clamp plate 142, and the clamping force is larger when the spacing between the second upper clamp plate and the second lower clamp plate is smaller. The tightening force of the tightening device 15 may be implemented by the spacing between the first clamping device 13 and the second clamping device 14 after the first clamping device 13 and the second clamping device 14 respectively clamp both ends of the bag mouth of the bag to be packaged, and the tightening force is larger when the spacing is larger.
For instance, the controller 11 may store a plurality of groups of plastic package parameters of the plastic package device. According to item parameters of bags to be packaged with different specifications, the controller 11 may control the plastic package device to seal the bag mouth of the bag to be packaged according to different plastic package parameters. Thus, all kinds of bags to be packaged with different specifications can be well sealed. For instance, the item parameters include the materials, the thicknesses and the like of the bags to be packaged. The plastic package parameters include the plastic package temperature, the pressing force, the plastic package time and the like of the plastic seal bar 17. It should be noted that the pressing force of the plastic seal bar 17 is implemented by the spacing between the plastic seal bar 17 and the surface of the stage 12, and the pressing force is larger when the spacing is smaller. When the bag to be packaged is sealed by thermoplastic means, both the plastic package temperature and the plastic package time of the plastic seal bar 17 have a significant impact on the package yield of the bags to be packaged.
For instance, as shown in
For instance, the vacuum-pumping device 19 further includes an air extractor. The air extractor is connected with the flat exhaust tube 18 and configured to generate exhaust airflow. The air extractor is, for instance, a vacuum pump.
