[0002] Paper bags have many uses. They can be used as shopping bags, gift packaging, and small item storage to meet people's daily needs. Advertisements can also be printed on paper bags to help companies promote their brands. At the same time, the environmental friendliness of paper bags has also made them widely used and promoted in modern society. For the convenience of storage or transportation, multiple paper bags are placed next to each other in a packaging box. In the process of placing paper bags in packaging boxes, since the paper bags have just been produced, the paper bags will be relatively fluffy. In this way, they need to be squeezed and packaged into the packaging box manually during the placement process. The packing process is cumbersome, and the paper bags are easily squeezed and deformed, and the packaging effect is not good, which affects the subsequent use of the paper bags.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1 , Figure 2 and Figure 3 As shown in the figure, the utility model is a paper bag packaging device, comprising a frame 10, a pushing device 30 arranged on the frame for pushing a paper bag group, and a packaging device 20 for wrapping the arrived paper bag group. Here, the paper bag group is composed of a plurality of horizontal paper bags 8 such as Figure 7 Superimposed.

[0027] like Figure 1 As shown, the frame 10 includes a lower bracket 11, a table top 12 arranged on the lower bracket 11, and an upper bracket 13 arranged on the table top 12.

[0028] like Figure 1 , Figure 2 and Figure 5As shown, the packaging device 20 includes a film unwinding mechanism 21 for unwinding a film, a pressing mechanism 22 located in front of the film unwinding mechanism 21 for pressing the arriving paper bag group, and a sealing mechanism 23 located at the rear end of the pressing mechanism for cutting and ironing the film of the wrapped paper bag group.

[0029] like Figure 1 and Figure 5 As shown, the film unwinding mechanism 21 includes an upper wheel assembly, a lower wheel assembly 211 and a film-drawing cylinder 213 that are symmetrically arranged at the upper and lower parts. The upper and lower wheel assemblies 211 each include a pair of unwinding wheels 2111. A brake 212 is provided on the rotating shaft of each unwinding wheel 2111. There are two film-drawing cylinders 213, and the two film-drawing cylinders 213 are fixed to the upper bracket 13. Each film-drawing cylinder 213 is respectively connected to the brake 212 on the upper and lower unwinding wheels 2111 on the same side. In addition, the film unwinding mechanism 21 also includes a plurality of guide wheels 214 distributed on the frame. A whole roll of film 9 is placed on each unwinding wheel 2111, and the ends of the upper and lower whole rolls of film 9 on the same side are connected together after passing through the corresponding guide wheels 214 in sequence.

[0030] like Figure 2 and Figure 5 As shown, there are two pressing mechanisms 22, which are symmetrically fixed on the frame on the left and right. Each pressing mechanism 22 includes a pressing plate cylinder 221 fixed on the upper bracket and a pressing plate 222 driven to rise and fall by the pressing plate cylinder 221. In this embodiment, the bottom surface of the pressing plate 222 has a groove 223. The groove 223 allows the film to pass through, so that when the pressing plate 222 presses the film downward to press the paper bag group, the film 9 is located in the groove 223 of the pressing plate 222, so that the film 9 can be tightened.

[0031] like Figure 4 , Figure 5 and Figure 6As shown, there are two hot sealing mechanisms 23. Each hot sealing mechanism 23 includes a cutter cylinder 231 fixed on the upper surface of the rear end of the corresponding pressure plate 222, and a cutter 232 driven to rise and fall by the cutter cylinder. A heating element 237 is installed inside the cutter 232. A temperature controller (not shown in the figure) electrically connected to the heating element 237 is arranged on the frame. A notch 233 is opened on the table 12 at the position corresponding to the cutter 232. A cutter pad 234 is arranged in the notch 233. A cutter pad cylinder 235 for driving the cutter pad 234 to rise and fall is fixed on the lower bracket 11. The cutter pad 234 can play a buffering and heat-insulating effect. A hole 236 for the film 9 to pass through is opened on the table 12 behind the notch 233. The end of the lower rolled film 9 passes through the hole 236 and is adhered to the end of the upper rolled film 9. It should be noted that the sealing mechanism 23 cuts and seals the film 9 along the rear end of the paper bag group, thereby wrapping the paper bag group. At the same time, the new ends of the upper and lower roll films 9 are also connected by heat.

[0032] like Figure 1 As shown, in addition, a pre-pressing device 40 for pre-pressing the paper bag group is provided on the frame 10 behind the packing device 20. The pre-pressing device 40 includes a pre-pressing plate 41 and a pre-pressing plate lifting cylinder 42 fixed on the upper bracket 13 to drive the pre-pressing plate to rise and fall.

[0033] like Figure 1 As shown, baffles 14 are respectively provided on both sides of the conveying path of the paper bag group above the table 12. The baffles 14 can limit the left and right sides of the paper bag group. The length of one of the baffles 14 is smaller than the length of the table 12, so that an opening is formed on one side near the initial position of the conveying path, so that the paper bag group can be pushed into the initial position of the conveying path from the opening.

[0034] like Figure 5 As shown, the pushing device 30 is divided into a first pushing mechanism 31, a second pushing mechanism 32 and a third pushing mechanism 33 in sequence along the conveying direction of the paper bag group.

[0035] like Figure 1 and Figure 2 As shown, the first material pushing mechanism 31 comprises a first push plate translation cylinder 311 fixed to one side of the rear end of the platform 12, a slide 312 driven by the first push plate translation cylinder 311, a first push plate lifting cylinder 313 fixed to the slide 312, and a first push plate 314 driven to rise and fall by the first push plate lifting cylinder 313. In this embodiment, the bottom surface of the first push plate 314 is provided with an insert block 315 extending downward, and a transverse slot 316 extending along the conveying direction of the paper bag group is opened at a position on the platform 12 corresponding to the insert block 315.

[0036] like Figure 3 and Figure 5 As shown, the second material pushing mechanism 32 includes a push rod translation cylinder 321 fixed on the lower bracket 11, a push rod lifting cylinder 322 fixed on the output end of the push rod translation cylinder 321, and a push rod 323 driven to rise and fall by the push rod lifting cylinder 322. A clearance groove 324 for avoiding the push rod 323 is opened on the table 12.

[0037] like Figure 5 As shown, the third pushing mechanism 33 includes a second push plate translation cylinder 331 fixed on the upper bracket 13, a second push plate lifting cylinder 332 fixed on the output end of the second push plate translation cylinder 331, and a second push plate 333 driven to rise and fall by the second push plate lifting cylinder 332.

[0038] The above is the paper bag packaging equipment of the utility model, and its working method is as follows:

[0039] During operation, the paper bag group is first placed at the initial position on the conveying path of the table 12. Subsequently, the first push plate lifting cylinder 313 drives the first push plate 314 to descend and is located behind the paper bag group. At the same time, the push rod translation cylinder 321 and the push rod lifting cylinder 322 in the second pushing mechanism 32 cooperate with each other to drive the push rod 323 to be located in front of the paper bag group. Afterwards, the first push plate translation cylinder 311 drives the first push plate 314 to move forward against the rear end of the paper bag group and pushes the paper bag group to move toward the pre-pressing device 40. At the same time, the push rod translation cylinder 321 drives the push rod 323 to move forward. Here, the push rod 323 is located in front of the paper bag group and moves forward with the paper bag group, which can prevent the paper bag group from tipping over during the forward movement.

[0040] When the paper bag group is pushed to the pre-pressing device 40, the push rod lifting cylinder 322 in the second pushing mechanism 32 drives the push rod 323 to descend, and then the push rod translation cylinder 321 and the push rod lifting cylinder 322 cooperate with each other to drive the push rod 323 to move to the rear of the paper bag group. Then, the first push plate lifting cylinder 313 and the first push plate translation cylinder 311 cooperate with each other to drive the first push plate 314 to return to the initial position to wait for the next paper bag group to be packaged. After that, the pre-pressing plate lifting cylinder 42 drives the pre-pressing plate 41 to descend, and the pre-pressing plate 41 contacts the top surface of the paper bag group and continues to descend to press the entire paper bag group. After the pre-pressing is completed, the pre-pressing plate lifting cylinder 42 drives the pre-pressing plate 41 to rise back to the initial position, waiting for the first pushing mechanism 31 to push the next paper bag group over for the next pre-pressing action.

[0041] Subsequently, the push rod translation cylinder 321 drives the push rod 323 to move forward against the rear end of the paper bag group, and pushes the paper bag group to move toward the clamping mechanism 22. At the same time, the film-pulling cylinder 213 extends to release the brake 212 and the corresponding unwinding wheel 2111, and the film 9 relaxes. The film 9 first contacts the front end surface of the paper bag group and wraps it. Subsequently, as the push rod 323 pushes the paper bag group to move toward the clamping mechanism 22, the unwinding wheel 2111 naturally unwinds, so the bottom surface of the paper bag group is wrapped by the film. At this time, although there is also a film 9 above the paper bag group, the film does not wrap the top surface of the paper bag group, but is only tilted and loosely located above the paper bag group. When the paper bag group is pushed to the clamping mechanism 22, the push rod translation cylinder 321 drives the push rod 323 to move backward, and the pressure plate cylinder 221 drives the pressure plate 222 to descend. During the descent of the pressure plate 222, it first contacts the film above the paper bag group and continues to descend while pressing the film. At this time, the film is just located in the groove of the pressure plate. When the pressure plate 222 contacts the top surface of the paper bag group and continues to descend to press the entire paper bag group, the film pulling cylinder 213 contracts to make the brake 212 brake the corresponding unwinding wheel 2111. Subsequently, the cutter pad cylinder 235 drives the cutter pad 234 to rise. The cutter pad 234 contacts the film 9 and rises along the rear end surface of the paper bag group against the film 9 to a level higher than the bottom surface of the paper bag group. At the same time, the cutter cylinder 231 drives the cutter 232 to descend. The cutter head of the cutter 232 contacts the film 9 and descends along the rear end surface of the paper bag group against the film 9 to contact the surface of the cutter pad 234. At this time, the film 9 wraps the top surface and the rear end surface of the paper bag group respectively. Then, the temperature of the cutter 232 is controlled by the temperature controller to cut the film and iron it, thereby completing the wrapping of the entire paper bag group. Then, the pressing plate cylinder 221 drives the pressing plate 222 to rise, and the second push plate translation cylinder 331 and the second push plate lifting cylinder 332 cooperate to drive the second push plate 333 to push the paper bag group out of the platform 12. Then, the second push plate 333 returns to the initial position under the cooperation and drive of the second push plate translation cylinder 331 and the second push plate lifting cylinder 332, waiting for the next paper bag group to be wrapped to be pushed out.

[0042] In summary, the utility model can realize automatic wrapping of paper bag groups, realize uninterrupted production, thereby reducing production costs and improving work efficiency. Moreover, the wrapped paper bag groups are neat and beautiful, and are convenient for subsequent packaging and storage.

[0043] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
