Background
The plastic packaging bag is widely applied to daily life of people, such as shopping, household garbage loading and the like. The plastic packaging bag is manufactured by adopting a bag making machine. In order to ensure the quality of the bags produced by the bag making machine, a pressing device is generally arranged between the bag making machine and the plastic film unwinding roller to flatten the plastic film. The pressing device of the bag making machine, which is described in the publication "CN211591524U", mainly comprises a workbench, a support, a cylinder, a pressing plate and a feeding trough. In addition, a limiting mechanism and a leveling mechanism are arranged in the feeding groove. The plastic film is limited and leveled through the limiting mechanism and the leveling mechanism. However, the device is not effective in practical application.
The film wound on the current plastic film unwinding roller has a little offset. However, in the actual transfer process, the plastic film is in a relatively tight state under the traction of the transfer force generated by the bag making machine, and the transfer force is uniformly applied to the wide width of the plastic film, so theoretically, the plastic film with the offset can be automatically corrected under the traction of the transfer force and the limiting effect of the feeding groove. But this is not the case in practice.
The research and analysis show that the reason is as follows: because the tank bottom of last silo is comparatively level and smooth, after plastic film laminated the tank bottom of last silo, receive the influence of static and atmospheric pressure, plastic film will appear adsorbing the phenomenon on the tank bottom. When the plastic film has horizontal deviation, the deviated plastic film is difficult to move due to the influence of the adsorption action between the plastic film in the feeding groove and the groove bottom. And because the plastic film is softer, the phenomenon that the plastic film entering the feeding groove is folded along the side wall of the feeding groove can occur. Moreover, the plastic film with the fold will have a smaller width after being flattened by the flattening mechanism. Such a plastic film seriously affects the quality of the bag after the bag is made.

Detailed Description
The present invention will be further described with reference to the following examples, which are not intended to limit the scope of the present invention, and any modifications made by anyone within the scope of the claims of the present invention will still fall within the scope of the claims of the present invention.
Referring to fig. 1-2, the pressing device of the bag making machine of the present invention includes a device body 1. Device body 1 is equipped with material loading groove 2, is equipped with leveling roller 3 in the material loading groove 2. Last silo 2 between leveling roller 3 and the feed inlet of last silo 2 is equipped with a guide way section 4, and the deflector 5 that the slope was arranged is all installed to the both sides of guide way section 4, and two deflectors 5 constitute the uide hole of a gradual change formula, and the width that the uide hole is close to leveling roller 3 one side is unanimous with the inside width of last silo 2. A film loosening mechanism 6 is arranged in the guide groove section 4, and a plurality of air holes 7 penetrating through the bottom of the guide groove section 4 are formed in the bottom of the guide groove section 4 at the periphery of the film loosening mechanism 6.
Through the setting of film not hard up mechanism 6 and gas pocket 7, can effectually not hard up the processing to the plastic film in the guide way section 4 to avoid plastic film to adsorb the phenomenon on the tank bottom, and then do benefit to plastic film and remove under the guide effect of deflector 5, realize correcting, great improvement the quality of product.
The film loosening mechanism 6 comprises a mounting seat 11, a motor 12, a cam 13 and a lifting top block 14. The lifting jacking block 14 is a semi-cylinder which is arranged in an inverted mode, and the width of the lifting jacking block 14 is larger than that of the plastic film, so that the plastic film is integrally loosened. A through hole 15 is formed in the guide groove section 4, the mounting seat 11 is arranged below the through hole 15, elastic supporting pieces 16 composed of springs and telescopic rods are mounted at two ends of the mounting seat 11, the two elastic supporting pieces 16 support a lifting top block 14 together, and the lifting top block 14 is movably connected with the through hole 15 in an inserted mode. The motor 12 is installed on the installation base 11, the cam 13 is installed at the driving end of the motor 12, and the peripheral surface of the cam 13 is in contact connection with the bottom surface of the lifting top block 14. In this embodiment, the bottom surface of the lifting top block 14 is a plane. Namely, the contact surface of the lifting top block 14 and the plastic film is an arc surface.
Through the driving action of the motor 12 and the cam 13 on the lifting top block 14, the lifting top block 14 can lift up and down, a pair of vibration actions for loosening the plastic film is formed, and the loosening of the plastic film is realized. In addition, in the present embodiment, the film loosening mechanism 6 is independently installed, so that the influence of vibration generated by the film loosening mechanism 6 on the apparatus body 1 can be avoided, and the stability of the apparatus body 1 is improved.
In implementing the technical solution of the present embodiment, the vibration amplitude of the lifting top block 14 should not be too large. When the lifting top block 14 works, the highest protruding height protruding out of the bottom of the guide groove section 4 is not larger than 5mm, so that the phenomenon that the plastic film is too stretched due to too high protruding height is avoided. In addition, the more preferred choice for the motor 12 is a 1000-2000 rpm motor. I.e. the vibration frequency of the lifting top block 14 is 1000-2000Hz. Through the arrangement, the plastic film can vibrate at a high frequency, and the phenomenon that the plastic film is adsorbed to the guide groove section 4 is well prevented.
Preferably, all be equipped with a guide board 8 between two deflector 5 and the flattening roller 3, the width between two guide boards 8 is unanimous with the inside width of last silo 2 to carry on spacingly to the plastic film after correcting.
Preferably, both ends of leveling roller 3 are all fixedly mounted with spacing cones 9, and the width between two spacing cones 9 is the same as the inner width of feeding chute 2, so as to avoid the phenomenon of displacement of plastic film when leveling.
Preferably, one side of each of the two limiting cones 9 opposite to each other is provided with a positioning platform 10 to improve the reliability of positioning the plastic film. The connecting part of the positioning platform 10 and the conical surface of the limiting cone 9 is of a round angle structure.
The utility model discloses a theory of operation is: when the pressing device is started to press the plastic film in the conveying process, the motor 12 is also started at the same time. The motor 12 drives the cam 13 to rotate, and the lifting top block 14 is continuously lifted through the action of the cam 13 on the lifting top block 14, so that the plastic film is jacked up to generate vibration, and the plastic film is prevented from being adsorbed with the bottom of the guide groove section 4.
In the process of conveying the plastic film, when the plastic film has no offset, the plastic film will enter the feeding chute 2 of the leveling roller 3 far away from the guide groove section 4 along the guide groove section 4 after being leveled by the leveling roller 3.
If the plastic film has a deviation phenomenon, the plastic film is dragged by the transmission force on one hand, and on the other hand, the plastic film is vibrated and loosened under the action of the lifting top block 14, so that no adsorption effect exists between the plastic film and the bottom of the guide groove section 4; and under the guiding action of the guide plate 5, the plastic film is corrected to the central position of the guide groove section 4 along the guide plate 5, so that the central position of the plastic film is consistent with the central position of the guide groove section 4, and the correction of the plastic film is realized.
The above is only the preferred embodiment of the present invention, and it should be noted that for those skilled in the art, without departing from the structure of the present invention, several modifications and improvements can be made, which will not affect the utility model and the utility of the patent.
