DETAILED DESCRIPTION

[0037] like Figures 1-6 As shown, the seasoning sauce packaging machine described in this application includes:

[0038] The rack 1, specifically, is a square cabinet structure.

[0039] a film unwinding mechanism 2, which is arranged on one side of the frame 1 and is used to unwind the packaging film;

[0040] Please refer to the following for details Figure 3 The film-releasing mechanism 2 includes a film-releasing roller 21 and an adjusting wheel 22. The film-releasing roller 21 is in the shape of a round roller, and its end is rotatably connected to the frame 1 through a hole-shaft fit, so that the film-releasing roller 21 is in a rotatable state. The outer diameter of the film-releasing roller 21 is adapted to the inner diameter of the rolled packaging film, so that the rolled packaging film can be sleeved on the outside of the film-releasing roller 21 and rotate synchronously with the film-releasing roller 21.

[0041] The adjusting wheel 22 is disposed obliquely above the film unwinding roller 21 and is rotatably connected to the frame 1 via a curved connecting plate 23. Specifically, one end of the curved connecting plate 23 is rotatably connected to the frame 1 via a bolt (not shown) and is secured to the frame 1 via a nut on the other side. When the nut is loosened, the curved connecting plate 23 can rotate relative to the frame 1, thereby allowing the adjusting wheel 22 at the end of the curved connecting plate 23 to rotate, moving it closer to or further away from the film unwinding roller 21. The adjusting wheel 22 is connected to the curved connecting plate 23 via a transfer shaft, allowing the adjusting wheel 22 to rotate. When packaging film is unwinding from the film unwinding roller 21, the adjusting wheel 22 contacts the surface of the packaging film. By adjusting the rotation angle of the curved connecting plate 23, the tightness of the packaging film can be adjusted, ensuring that the packaging film can be smoothly transported outward.

[0042] The film placing mechanism 2 of the above structure has the advantages of stable film placing and simple operation.

[0043] The film guide mechanism 3 is arranged along the conveying path of the packaging film and is used to guide the conveying of the packaging film; please refer to Figure 4The film guide mechanism 3 includes a mounting frame 31, a film guide roller 32, an adjusting arm 34 and an adjusting roller 35. The mounting frame 31 is an L-shaped plate, which is vertically arranged obliquely above the film placing mechanism 2. The film guide roller 32 is cylindrical and is rotatably connected to the mounting frame 31 through a connecting arm 33 and is fastened by bolts. The film guide roller 32 is rotatably connected to the connecting arm 33. Specifically, the film guide roller 32 is rotatably connected to the connecting arm 33 through a transfer shaft, so that the film guide roller 32 can rotate relative to the connecting arm 33 around the axis of the transfer shaft. There are two film guide rollers 32, and the two guide rollers are connected. The film rollers 32 are positioned relative to each other, with the packaging film in contact with the outer surface of the film guide roller 32. The film guide roller 32 guides the packaging film. The connecting arm 33 is in the shape of an elongated plate, with the end away from the film guide roller 32 being rotatably connected to the mounting bracket 31 via a bolt (not shown). Similarly, when the nut is loosened, the connecting arm 33 can rotate relative to the mounting bracket 31 to adjust the angle of the film guide roller 32 and, therefore, the direction of the film guide. In other optional embodiments, the number of film guide rollers 32 can be set according to actual needs, and this embodiment is not limited thereto. In a preferred embodiment, the connecting arm 33 is provided with an oblong hole, and the mounting bracket 31 is provided with multiple connection holes, so that the connection position of the connecting arm 33 and the mounting bracket 31 is adjustable, thereby expanding the position adjustment range of the connecting arm 33.

[0044] An adjusting roller 35 is provided obliquely above the film guide roller 32. The adjusting roller 35 is mainly used to adjust the direction and tightness of the packaging film conveying. After the packaging film passes through the film guide roller 32, it is wrapped around the outer surface of the adjusting roller 35 and then extends downward. The adjusting roller 35 is rotatably connected to the adjusting arm 34, and the adjusting arm 34 is rotatably connected to the mounting bracket 31 by bolts. The specific transfer structure is the same as the above-mentioned connecting arm 33 structure, which can be understood by referring to the above description and will not be repeated here.

[0045] The film guiding mechanism 3 can realize the guiding and tightness adjustment of the packaging film, so that the packaging film can be transported more smoothly.

[0046] The bag making mechanism 4 is arranged on the conveying path of the packaging film and is used to make the packaging film fold and wind; Figure 5The bag-making mechanism 4 includes a stacking shaft 41 and a U-shaped tube 42. One end of the stacking shaft 41 is connected to the frame 1 and is located in the conveying path of the packaging film. The U-shaped tube 42 is arranged around the outer side of the stacking shaft 41, with its closed end located at the end of the stacking shaft 41 away from the frame 1. This forms a U-shaped gap between the stacking shaft 41 and the U-shaped tube 42. In one specific embodiment, the axial direction of the stacking shaft 41 is perpendicular to the axial direction of the film guide roller 32. Before production begins, when unwinding the packaging film, the packaging film is passed around the adjustment roller 35 and pulled downward. It is then manually twisted 90 degrees and folded in half to enter the U-shaped gap. The stacking shaft 41 is located between the two folded layers of packaging film, used to hold the two layers apart to prevent adhesion. At this point, the bag-making mechanism 4 folds the packaging film in half to form a bag-shaped structure with one side closed, completing the bag-making process.

[0047] The heat sealing mechanism 5 includes a heat sealing roller group, which includes a first heat sealing roller 51, a second heat sealing roller 52 and a third heat sealing roller 53 arranged in sequence along the conveying path of the packaging film, and is used to heat seal the packaging film;

[0048] Please refer to the following for details Figure 6 The first heat-sealing roller 51 has side sealing strips 511 at both ends that protrude outward to a level higher than the roller surface of the first heat-sealing roller 51. That is, the first heat-sealing roller 51 has a structure that is high at both ends and concave in the middle. When the first heat-sealing roller 51 contacts the packaging film, only the side sealing strips 511 contact the bag-shaped structure for heat sealing, and do not contact the middle part of the bag-shaped structure.

[0049] The outer roller surface of the second heat-sealing roller 52 protrudes outward to form a plurality of transverse sealing strips 521 that are higher than the roller surface of the second heat-sealing roller 52. The transverse sealing strips 521 extend along the axial direction of the second heat-sealing roller 52, and the plurality of transverse sealing strips 521 are arranged at equal intervals along the circumference of the second heat-sealing roller 52. The structure of the third heat-sealing roller 53 is the same as that of the second heat-sealing roller 52. With this structure of the second heat-sealing roller 52 and the third heat-sealing roller 53, the spacing between two adjacent transverse sealing strips 521 is equal to the spacing between the sealing openings at the upper and lower ends of the sauce bag, so that the packaging film can be intermittently transversely sealed during the transportation of the packaging film to form sealing openings with equal intervals.

[0050] The heat sealing mechanism 5 also includes a heating box 54, which is arranged on one side of the heat sealing roller group. Three heating elements are provided in the heating box 54. The three heating elements correspond to and are in thermal contact with the three heating rollers respectively. The three heating elements heat the three heating rollers respectively so that they have a high temperature to heat-seal the packaging film. In a specific embodiment, the heating element can be a resistive heater or an electrode heater, which is not limited in this embodiment.

[0051] The heat-sealing mechanism 5 also includes a motor (not shown) and a gear set 55. The motor and gear set 55 are linked together. The gear set 55 has three output terminals, which are respectively connected to the first heat-sealing roller 51, the second heat-sealing roller 52, and the third heat-sealing roller 53. The motor drives the three heat-sealing rollers through the gear set 55, thereby providing power for conveying the packaging film.

[0052] The heat sealing mechanism 5 can realize three-port heat sealing of the bag-shaped structure and realize continuous production.

[0053] Injection mechanism 6, please refer to Figure 5 The injection mechanism 6 includes an injection pump 61 and an injection tube 62 connected to the injection pump 61. The discharge end of the injection tube 62 extends into the packaging film conveying path near the second heat-sealing roller 52 for injecting the sauce. Specifically, the injection tube 62 is positioned corresponding to the middle of the aforementioned U-shaped tube 42, so that the injection tube 62 can correspond to the middle of the bag structure and will not interfere with the bag's conveying. When the injection pump 61 is in operation, it is connected to an external material barrel, pumping the sauce into the bag, and then delivering it through the injection tube 62 to the bag structure.

[0054] Furthermore, in this embodiment, the seasoning sauce package machine also includes a receiving hopper 7, which is located below the heat sealing mechanism 5 and is used to receive the sauce package that has been filled and heat-sealed.

[0055] The following will combine the above content to fully explain the working process of the seasoning sauce packaging machine described in this embodiment.

[0056] Before the equipment is started, the rolled packaging film is placed on the film placing roller 21, and the packaging film is pulled outward, passes through the film guiding rollers 32 of the film guiding mechanism 3, bypasses the adjusting roller 35, and is pulled downward. The packaging film is twisted 90 degrees and folded in half to enter the U-shaped gap formed above. The winding shaft 41 is located between the two folded layers of packaging film, stretching the packaging film to complete the preliminary bag making. Then, the folded packaging film is passed downward through the three heat sealing rollers in sequence to ensure that the packaging film is in close contact with the side seals 511 and transverse seals 521 of the heat sealing rollers.

[0057] The heating element in the heating box 54 is activated to preheat the three heat-sealing rollers. After preheating to the required temperature, the motor is started, which drives the three heat-sealing rollers to start, pulling the packaging film forward. Within one operation cycle, the packaging film passes through the bag-making mechanism 4 to initially form a bag-shaped structure. It then enters the first heat-sealing roller 51, which heat-seals the opening on the other side. The film then enters the second heat-sealing roller 52, where one of the transverse sealing strips 521 transversely seals the bottom of the bag-shaped structure. At this point, the bag-shaped structure only has an opening at the top. Since the end of the injection tube 62 is located near the second heat-sealing roller 52, that is, above the bottom seal, the injection pump 61 is activated to inject the sauce into the bag. After the specified amount is injected, the injection pump 61 is stopped, and the bag continues to be transported forward until it enters the third heat-sealing roller 53, which heat-seals the upper opening of the bag-shaped structure, thus completing the production of a single sauce bag. Repeating these steps can produce multiple sauce bags.
