DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figure 1-6, A film - covering machine bag - making mechanism, including a bag - making component 1, the bag - making component 1 is composed of a film - feeding mechanism 2 and a film - making mechanism 3. The film - feeding mechanism 2 is arranged below the film - making mechanism 3, and a bag - film roll 100 is arranged on the film - feeding mechanism 2.

[0021] The film - making mechanism 3 is composed of a cutting - knife mechanism 31, a film - supporting mechanism 32, a film - pushing mechanism 33, a vertical - arm return - force mechanism 34, a film - sensing mechanism 35, a film - pressing mechanism 36 and a non - powered roller 37. The film - supporting mechanism 32 is arranged on the left side of the cutting - knife mechanism 31. The film - pushing mechanism 33 is arranged at the bottom of the cutting - knife mechanism 31 and on the right side of the film - supporting mechanism 32. The vertical - arm return - force mechanism 34 is arranged on the bracket of the film - pressing mechanism 36 and on the left side of the film - supporting mechanism 32. The film - sensing mechanism 35 is arranged on the bracket of the film - pressing mechanism 36 and on the right side of the vertical - arm return - force mechanism 34. The film - pressing mechanism 36 is arranged on the left side of the film - supporting mechanism 32. The non - powered roller 37 is arranged on the bracket of the film - pressing mechanism 36. A number of photoelectric sensors are arranged on the film - sensing mechanism 35. A motor 4 is arranged on the film - feeding mechanism 2. Removable return - force devices are respectively arranged on both sides of the vertical - arm return - force mechanism 34. Cylinders 5 are arranged on both the cutting - knife mechanism 31 and the film - pushing mechanism 33. A rotating wheel 6 is arranged on the film - pressing mechanism 36. Thorns 7 are arranged on the inner wall of the rotating wheel 6. The length of the thorns 7 can be adjusted by set screws to avoid being too long or too short and affecting bag - making.

[0022] Furthermore, when threading the film, there is no need to overly wind the non - powered roller 37. Only need to lift the vertical - arm return - force mechanism 34 to the top, thread the bag - film through it, uncover the film material and put it on the film - supporting mechanism 32, then release the vertical - arm return - force mechanism 34, thus replacing the complex film - winding link.

[0023] Through the mutual cooperation of the film - feeding mechanism 2, the cutting - knife mechanism 31, the film - supporting mechanism 32, the film - pushing mechanism 33, the vertical - arm return - force mechanism 34, the film - sensing mechanism 35, the film - pressing mechanism 36, the non - powered roller 37, the bag - film roll 100, the motor 4, the cylinders 5, the rotating wheel 6 and the thorns 7, a film - covering machine bag - making mechanism is realized. There is no need to overly wind the non - powered roller 37, thus replacing the complex film - winding link. Moreover, a detachable return - force device is added, which can change the tension of the film during film - making according to the actual situation of pulling the film. At the same time, the photoelectric sensors can change the film - feeding speed according to different pulling - film lengths. The length of the thorns 7 in the film - pressing mechanism 36 can be adjusted as needed to avoid being too long or too short and affecting bag - making, facilitating film threading and bag - making, and improving the practicability and convenience.

[0024] During use, we directly place the bag film roll 100 in the film feeding mechanism 2, adjust the position of the film roll, pull out the bag film. The bag film first passes through the film pressing mechanism 36 and then winds around the unpowered roller 37 and the vertical arm return force mechanism 34, and then is sleeved into the film supporting mechanism 32. When making bags, due to the pulling force, the vertical arm return force mechanism 34 passes through multiple photoelectric sensors on the film induction mechanism 35, prompting the motor 4 of the film feeding mechanism 2 to feed the film. After other mechanisms finish pulling the film, the cutter mechanism 31 and the film pushing mechanism 33 are quickly closed and sealed under the drive of the cylinder 5.

[0025] In summary, for the bag making mechanism of this film covering machine, through the mutual cooperation of the film feeding mechanism 2, the cutter mechanism 31, the film supporting mechanism 32, the film pushing mechanism 33, the vertical arm return force mechanism 34, the film induction mechanism 35, the film pressing mechanism 36, the unpowered roller 37, the bag film roll 100, the motor 4, the cylinder 5, the rotating wheel 6 and the thorn wheel needle 7, the problems raised in the above-mentioned background technology are solved.
