Description

Technical Field

[0001] The utility model relates to the field of packaging, in particular to an anti-sticking bag packaging machine. Background Art

[0002] In the traditional production of filling packaging, the inner bag is not treated to prevent sticking, resulting in the situation that the filling sticks to the bag and wastes when consumers open the bag to take out the filling, resulting in a poor experience. In order to overcome the above problems, the inner bag of the packaging bag is currently brushed with oil before the filling is bagged to prevent the filling from sticking to the bag, but the amount of oil brushed is difficult to control, which is inconvenient to use, and the oil brush is difficult to apply in the production process of the vertical bag filling packaging machine. Utility Model Content

[0003] The utility model aims to overcome the shortcomings of the prior art and provide an anti-sticking bag packaging machine which can spray oil on a vertical bag filling packaging machine.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an anti-stick bag packaging machine, comprising a feeding barrel and an oil spray assembly, the oil spray assembly is installed on the outside of the feeding barrel, the oil spray assembly comprises a support barrel, an oil delivery pipe, an oil delivery pump and an oil spray nozzle, the bottom of the feeding barrel extends outward to form an annular support plate, the support barrel sleeve is placed on the outside of the feeding barrel and stands on the support plate, the inner surface of the support barrel is provided with a mounting groove, the oil delivery pipe is placed in the mounting groove, and a mounting port is provided on the support plate directly below the mounting groove, the oil spray nozzle is installed on the mounting port and connected to the oil delivery pipe, and the other end of the oil delivery pipe is connected to the oil delivery pump.

[0005] Furthermore, a feeding hopper is arranged on the upper part of the feeding cylinder, a fixing piece is arranged below the feeding hopper, the fixing piece does not contact with the supporting cylinder, and the oil delivery pipe extends backward from below the fixing piece.

[0006] Furthermore, the outer diameter of the support tube is greater than or equal to the outer diameter of the support plate.

[0007] Furthermore, a transverse sealer is provided below the feeding cylinder, and the transverse sealer includes two transverse sealing parts.

[0008] Furthermore, there are two fuel injection nozzles, one of which is arranged in a direction close to one of the transverse sealing members, and the other fuel injection nozzle is arranged in a direction close to the other transverse sealing member.

[0009] Furthermore, it also includes a bag making and forming device, which is installed on the upper part of the supporting tube.

[0010] The beneficial effects of the utility model are as follows: by arranging an oil spray assembly on the feeding barrel, the packaging bag can be sprayed with oil before the feeding barrel feeds the material, so as to prevent the filling from sticking to the bag and causing waste of filling when the bag is opened and the filling is taken out, thereby avoiding reducing the user experience; in addition, the two oil spray nozzles are respectively arranged in directions close to different transverse sealing parts. After the transverse sealer seals the packaging bag, the two directions correspond to the two inner surfaces of the packaging bag, so that the sprayed oil can cover the two inner surfaces of the packaging bag, thereby achieving a better anti-sticking effect.

DETAILED DESCRIPTION

[0016] The utility model is further described below in conjunction with the accompanying drawings.

[0017] Embodiment: An anti-stick bag packaging machine includes a feeding barrel 2 and an oil spray assembly. The feeding barrel 2 is used to deliver fillings and other materials into the packaging bag. The oil spray assembly is installed on the outside of the feeding barrel 2. The oil spray assembly includes a support barrel, an oil delivery pipe 4, an oil delivery pump 5 and an oil spray nozzle 7. The bottom of the feeding barrel 2 extends outward to form an annular support plate 3. The support barrel 1 is sleeved on the outside of the feeding barrel 2 and stands on the support plate 3. The inner surface of the support barrel 1 is provided with two mounting grooves 11. The two mounting grooves 11 are provided on the inner surface of the support barrel 1. The oil delivery pipes 4 are respectively placed in two installation grooves 11, and an installation port 31 is provided on the support plate 3 directly below the installation groove 11. The oil nozzle 7 is installed on the installation port 31 and connected with the oil delivery pipe 4. The other end of the oil delivery pipe 4 is connected with the oil delivery pump 5. The oil delivery pump 5 can control the single oil delivery amount more accurately. Before the material is put into the feeding pipe, the oil delivery pump 5 draws the oil in the oil storage tank 6 and sprays it onto the inner surface of the packaging bag through the oil nozzle 7 to prevent the filling from sticking to the bag, avoid filling waste and reduce the user experience.

[0018] Furthermore, a feeding hopper 21 is provided on the upper part of the feeding barrel 2, a fixing part 8 is provided below the feeding hopper 21, support rods are provided on both sides of the fixing part 8 and are connected to the frame of the packaging machine, the fixing part 8 does not contact the supporting barrel 1, and the oil delivery pipe 4 extends backward from the bottom of the fixing part 8 and is connected to the oil delivery pump 5.

[0019] Furthermore, the outer diameter of the support tube 1 is greater than or equal to the outer diameter of the support plate 3 to prevent the support plate 3 from scratching the packaging bag.

[0020] Furthermore, a transverse sealer 94 is provided below the feeding tube 2. The transverse sealer 94 includes two transverse sealing parts. The transverse sealer is used to seal the feeding bag to turn it into a sealed packaging bag.

[0021] Furthermore, there are two oil spray nozzles 7, one of which is arranged in a direction close to one of the transverse seals, and the other is arranged in a direction close to the other transverse seal. After the transverse sealer 94 is sealed, the packaging bag forms two inner surfaces. The two directions of the oil spray nozzles 7 correspond to the two inner surfaces of the packaging bag, respectively, so that the sprayed oil can cover the two inner surfaces of the packaging bag, thereby achieving a better anti-sticking effect.

[0022] Furthermore, it also includes a bag former 91, which is preferably a lapel bag former. The bag former 91 is installed on the upper part of the support tube 1. The film is turned into a cylindrical shape by the bag former and wrapped on the support tube 1. The material bag is located below the opening on the installation groove and will not block the oil delivery pipe 4. The cylindrical film is longitudinally sealed by the longitudinal sealer 93, and the film-pulling synchronous belt 92 pulls the longitudinally sealed material bag downward, and the transverse sealer seals the edge. The bag former 91, the longitudinal sealer 93, the film-pulling synchronous belt 92 and the transverse sealer 94 are common components of the vertical bag filling and packaging machine, and will not be elaborated here.

[0023] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
