[0013] The utility model will be further described below in conjunction with the accompanying drawings.

[0014] Please refer to Figure 1-3 The utility model is a film pressing device for a bag making machine, comprising a processing box 1, one end of the processing box 1 and the side walls on both sides of the opening are fixedly connected with a fixed plate 2, the fixed plate 2 is far away from the processing box 1 and the opposite side walls are fixedly connected with an auxiliary plate 3, a movable groove 8 is opened inside the processing box 1, and the movable groove 8 is rotatably connected with a pressing roller 11, a pressing groove is opened inside the processing box 1 and below the movable groove 8, and the pressing groove is communicated with the movable groove 8, one side of the pressing roller 11 extends into the pressing groove, and the pressing groove is communicated with the openings opened on the side walls at both ends of the processing box 1;

[0015] A linkage rod 10 is rotatably connected in the middle of the side walls at both ends of the pressure roller 11, and the end of the linkage rod 10 away from the pressure roller 11 is fixedly connected to a connecting cross plate, and three springs 9 are evenly fixedly connected to the top side of the cross plate. The spring 9 is fixedly connected to the top side wall of the movable groove 8 through one end thereof, and a retractable damping rod is sleeved in each spring 9. The inside of the pressure roller 11 close to the surface wall is filled with an electric heating plate 12, and the bottom side wall of the pressing groove is inlaid with an auxiliary heating plate, and one side of the pressure roller 11 is in contact with the auxiliary heating plate.

[0016] A preferred technical effect of the present scheme is that the bag and the film are sent into the pressing groove through the auxiliary plate 3, and then pass through the three pressing rollers 11 in turn. Because the pressing roller 11 can rotate, the pressing roller 11 can be driven to rotate when the film and the bag pass through it. The rotation of the pressing roller 11 can fully press and heat seal the film and the bag, and can perform variable conveying and pressing and conveying without pausing in the middle, thereby ensuring the smooth and efficient processing process. The establishment of three pressing rollers 11 can also ensure efficient and stable pressing of the film.

[0017] The edges on both sides of the auxiliary plate 3 opposite to the processing box 1 are rotatably connected to the extrusion rod 13 through a torsion spring, and the end of the extrusion rod 13 away from the auxiliary plate 3 is fixedly connected to the leveling plate 14. The two extrusion rods 13 are both inclined structures, and both ends of the leveling plate 14 are both arc-shaped structures. A through groove is opened inside the auxiliary plate 3, and auxiliary rollers 15 are evenly rotatably connected on both sides of the through groove.

[0018] A preferred technical effect of the present scheme is that the film and the bag are passed through the auxiliary plate 3. Since the interior of the auxiliary plate 3 is a horizontal structure, the film and the bag can be initially bonded together. The auxiliary roller 15 set up inside the auxiliary plate 3 can assist in conveying the film and the bag. At the same time, the bubbles can be discharged through the initial squeezing of the auxiliary roller 15 to ensure the smoothness of subsequent processing. At this time, the film and the bag pass through the middle of the two leveling plates 14, which can improve the reliability of the bonding between the two and ensure that the two enter the pressing groove in a bonded state.

[0019] Two vertical columns 4 are set up on the side of the auxiliary plate 3 away from the processing box 1, and a winding roller 5 is rotatably connected between the two vertical columns 4. A pair of extension columns 6 are fixedly connected to the opposite side walls of the two vertical columns 4 and the auxiliary plate 3. The extension columns 6 are inclined structures and a pressing roller 7 is rotatably connected to one end away from the vertical columns 4. Bags and films are respectively wound on the two winding rollers 5.

[0020] A preferred technical effect of the present solution is that the two pressing rollers 7 can be set up to pull and position the film and the bag, and position the two close to each other, ensuring that the two can smoothly pass into the auxiliary plate 3, thereby increasing the efficiency of the equipment operation.

[0021] Specifically, when the utility model is used, the film and the bag are passed through the corresponding pressing rollers 7, and then passed into the auxiliary plate 3, and finally sent into the pressing groove in the processing box 1 from the middle of the two flat plates 14, and connected to the winding roller 5 for collection through the pressing groove. When the two are in the pressing groove, they will pass under the three pressing rollers 11 in turn, and the friction force drives the pressing rollers 11 to rotate, so as to achieve auxiliary transportation and uniform pressing of the film and the bag, because the pressing rollers 11 can roll on the film evenly and stably when rotating, and at the same time, corresponding electric heating plates 12 are set in the three pressing rollers 11, and the temperature gradually increases, so that the film can be evenly and stably heat-sealed on the bag, and the set spring 9 can ensure that the pressing roller 11 is always in stable contact with the film or bag, ensuring sufficient friction and providing downward pressure on the pressing roller 11, thereby increasing its pressing ability.

[0022] As another preferred solution, a motor can be installed in the movable groove 8, and a sprocket is connected to one end of each pressing roller 11, which is connected to the motor through a chain. Therefore, the function of driving the pressing roller 11 to actively rotate can be realized, thereby increasing the efficiency and effectiveness of pressing and heat sealing. In addition, the auxiliary heating plate embedded in the bottom of the pressing groove can cooperate with the pressing roller 11 to increase the efficiency and reliability of heat sealing.

[0023] The above are only preferred implementations of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.

[0024] Other parts of the present invention not described in detail belong to the prior art and will not be described here.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
