Description

Technical Field

[0001] The utility model relates to the technical field of material packaging, in particular to a small bag packaging machine. Background Art

[0002] Biscuit processing and packaging is to sort, stack and send the processed biscuits to the packaging mechanism for packaging. The biscuits are transported from the production line to the entrance of the packaging machine, and a certain amount of biscuits are poured into the packaging bag by the infusion mechanism. The packaging bag is clamped by the clamping mechanism. Under the action of the rotating mechanism, the infusion work can be completed for multiple packaging bags in turn. After that, the packaging bag is sealed by the sealing mechanism, and the packaged biscuits are transported by the conveyor belt.

[0003] Currently, biscuits are usually packaged using a multi-station packaging machine, such as the Chinese patent disclosed by Patent No. CN202421025922.3. Its packaging method is to pull the packaging bag open and then push the biscuits from the hopper into the packaging bag to achieve the purpose of automatic packaging. However, when some small biscuits are individually packaged, the required packaging bags are small, which makes it inconvenient to operate the filling and packaging machine. In addition, since the biscuits are flat in shape, it is not convenient to place the biscuits when the packaging bag is pulled open (unless the size of the packaging bag is at least 1.5 times that of the biscuits). At the same time, if the biscuits are pushed into the packaging bag during filling, they are likely to break and affect the shape of the biscuits. Utility Model Content

[0004] Therefore, in order to solve the above-mentioned shortcomings, the present invention provides a small bag packaging machine, which can be used to individually package small pieces of biscuits.

Any structural modification, change in proportional relationship or adjustment of size should still fall within the scope of the technical content disclosed in the present invention without affecting the efficacy and purpose that can be achieved by the present invention.

[0029] As described in the background art, existing filling and packaging machines are not convenient for pushing small pieces of material into packaging bags. Large packaging bags need to be pulled open to put small pieces of material in, and the material is easily broken, resulting in unnecessary losses.

[0030] For the reasons mentioned above, please refer to the attached Figure 1 ~Attached Figure 2 , the utility model provides a small bag packaging machine, including a feeding mechanism for uniformly conveying the material to be packaged;

[0031] The packaging mechanism is arranged on the side of the discharge end of the feeding mechanism;

[0032] The feeding mechanism is provided with an adjustable guide plate 3 for guiding the material, and the packaging mechanism is provided with a packaging film and a sealing and cutting mechanism for covering the material and achieving sealing cutting.

[0033] Please see the attached Figure 3Specifically, the feeding mechanism includes a conveying bracket 1 and a conveyor belt 2 arranged on the conveying bracket 1. The conveyor belt 2 is a narrow conveyor belt and conveys the material horizontally. Transition plates 5 are provided on both sides of the narrow conveyor belt. The ends of the transition plates 5 extend to the packaging mechanism for smoothly transitioning the material on the conveyor belt 2 to the packaging mechanism.

[0034] The arrangement of the narrow conveyor belt and the transition plates on both sides facilitates the smooth conveying of small pieces of material on the conveyor belt to the packaging mechanism for packaging.

[0035] Specifically, a connecting hole is provided on the transition plate 5, and a strip hole perpendicular to the conveying direction is provided on the guide plate 3. The guide plate 3 is installed on the transition plate 5 in an adjustable manner by a fastener 4 (i.e., a bolt) passing through the strip hole and maintaining a movably connected with the connecting hole.

[0036] The strip holes on the guide plates make it easy to adjust the distance between the two guide plates and the gap between the sides of the conveyor belt, thereby facilitating the guided transportation of different materials.

[0037] Please see the attached Figure 4 Specifically, the packaging mechanism includes a support frame 6 and support plates 16 arranged on both sides of the top of the support frame 6. Guide rollers 9 are rotatably arranged at both ends of the support frame 6. The transition plate 5 of the feeding mechanism extends to above any guide roller 9. A bottom film roller 7 is provided at the bottom of the support frame 6 near the feeding mechanism, and a tensioning roller 10 is provided at the bottom of the support frame 6 away from the feeding mechanism. The packaging film on the bottom film roller 7 passes through the gap between the guide roller 9 and the transition plate 5, and is tensioned on the tensioning roller 10 through another guide roller 9. A top film roller 8 is also provided above the support plate 16 near the feeding mechanism.

[0038] Specifically, a groove 17 is provided between the support plate 16 and the support frame 6. Both sides of the packaging film pass through the groove 17 and are tensioned and conveyed by rotating the guide rollers 9 and the tensioning roller 10 at both ends. Several rotatable pressing rollers 11 are provided on the inner side of the inner end of the support plate 16 near the feeding mechanism. The pressing rollers 11 are evenly distributed along the length direction of the support plate 16 and keep the bottom in contact with the side of the packaging film in the groove 17. The packaging film on the top film roller 8 passes through the gap between any two pressing rollers 11 and enters the groove 17 and is connected to the tensioning roller 10 through the guide roller 9.

[0039] By setting the installation positions of several film rollers in the packaging mechanism and the pulling direction of the packaging film, it is convenient to wrap the small pieces of material delivered from the feeding mechanism with the upper and lower layers of packaging film to form a package.

[0040] Specifically, a side sealing roller 12 is provided on the outer side of the pressing roller 11 away from the feeding mechanism. Heating steam is introduced into the inner end of the side sealing roller 12 and the side sealing roller 12 is rotatably installed to maintain the same height as the pressing roller 11 .

[0041] The side edges of the upper and lower packaging films are sealed by setting side sealing rollers.

[0042] Specifically, a transverse sealing mechanism and a cutting mechanism are arranged between the support plates 16 away from the feeding mechanism. The side sealing roller is combined with the transverse sealing mechanism and the cutting mechanism to form a sealing and cutting mechanism. The cutting mechanism is arranged on the inner side of the support plate 16 near the end. The transverse sealing mechanism includes a cam 13 rotatably arranged on the support plate 16 and a transverse sealing roller 14 connected to the cam 13. The transverse sealing roller 14 is liftably arranged above the support frame 6 and remains perpendicular to the conveying direction of the packaging film.

[0043] By setting the installation position of the transverse sealing roller and the lifting mode, it is convenient to perform transverse sealing on small pieces of material, thereby forming a single package of the small pieces of material.

[0044] Please see the attached Figure 4 and attached Figure 5 Specifically, the transverse sealing roller 14 includes limiting parts 14.1 at both ends and a connecting part 14.2 in the middle. The connecting part 14.2 passes through the vertical strip holes preset on the support plate 16 to keep sliding up and down. A sealing part 14.3 for introducing heating steam into the interior is provided at the bottom of the connecting part 14.2. The limiting parts 14.1 are respectively attached to the outer sides of the support plates 16. An elastic member 15 is connected to the bottom of the limiting part 14.1. A limiting frame 14.4 is provided on the top of the limiting part 14.1 and is sleeved on the outer end of the cam 13. The rotation of the cam 13 drives the transverse sealing roller 14 to squeeze the elastic member 15 downward intermittently to contact the packaging film to achieve transverse sealing of the packaging film.

[0045] The specific structure and connection mode of the transverse sealing roller are set to achieve transverse sealing of small pieces of material.

[0046] Specifically, the cutting mechanism is the same as the transverse sealing mechanism, except that the sealing portion at the bottom of the transverse sealing roller is a cutting portion. Since the cutting portion is in the shape of a conventional cutter, it is not shown in detail in the drawings. The specific structure can be referred to the transverse sealing mechanism.

[0047] Working principle: First, according to the shape of the material, the position of the guide plate 3 on both sides of the conveyor belt 2 is adjusted by rotating the fastener 4, and then the conveyor belt 2 is started to convey the material. The material is limited and conveyed by the guide plate 3 on the conveyor belt 2 until it moves to the end of the transition plate 5. Under the push of subsequent materials, it enters the packaging mechanism. The packaging film on the bottom film roller 7 in the packaging mechanism passes through the gap between the guide roller 9 and the transition plate 5, and is connected to the tensioning roller 10 after reaching the other guide roller 9. The material on the filter plate 5 falls onto the packaging film of the bottom film roller 7 under the conveying action of the conveyor belt 2. As the packaging film continues to move, After reaching the top film roller 8, the packaging film on the top film roller 8 is adhered to the top of the material under the pressing action of the pressing roller 11. Finally, the side edge of the packaging film is pressed and sealed by the side sealing roller 12, and then passes under the transverse sealing roller 14. The transverse sealing roller 14 squeezes the elastic part 15 downward under the rotation of the cam 13 (the speed of the cam 13 can be controlled according to the external control system to avoid the transverse sealing roller 14 from contacting the material and crushing the material when it is lowered). After the transverse sealing and cutting are completed, the cam 13 continues to rotate, and the elastic part 15 lifts the transverse sealing roller 14 to facilitate the continued transportation of the sealed and cut materials, and finally discharged from another guide roller 9, completing the automatic packaging and cutting process.

[0048] The above description is a detailed description of the preferred embodiments of the present invention, but the embodiments are not intended to limit the scope of the patent application of the present invention. All equivalent changes or modifications completed under the technical spirit suggested by the present invention should fall within the patent scope covered by the present invention.
