Description

Technical Field

[0001] The utility model relates to the field of longitudinal sealing and tearing of strip bags, in particular to a longitudinal sealing and tearing mechanism based on continuous multi-row strip bag equipment. Background Art

[0002] The tearing form of the existing continuous multi-row strip bag packaging equipment mostly adopts the longitudinal and transverse tearing to be pierced at the same time, and there is no separate longitudinal tearing cutting mechanism, so some bag types that require separate longitudinal tearing cannot be produced.

[0003] For example, a Chinese patent with publication number CN215098675U discloses a strip bag, including a strip bag body, a longitudinal sealing strip arranged on one side of the strip bag body, and a transverse sealing block arranged on one end of the strip bag body, wherein the connection line between the longitudinal sealing strip and the strip bag body is offset to one side of the center line of the strip bag body, the longitudinal sealing strip is provided with a longitudinal sealing easy-tear opening, and the transverse sealing block is provided with a transverse sealing easy-tear opening, and the longitudinal sealing easy-tear opening and the transverse sealing easy-tear opening are located on the same horizontal plane. A roll film forming device is also disclosed for forming the strip bag. The strip bag and the roll film forming device have the advantages of simpler forming process, reduced consumption of packaging materials, and reduced processing and manufacturing costs.

[0004] For another example, a Chinese patent with publication number CN207089826U discloses a semi-fluid food packaging machine with an easy-tear cutting device, which includes a frame, a longitudinal sealing mechanism for hot-pressing and sealing the longitudinal opening of the semi-fluid food packaging bag, and a transverse sealing mechanism for hot-pressing and sealing the transverse opening of the semi-fluid food packaging bag. The longitudinal sealing mechanism and the transverse sealing mechanism are arranged up and down and are independently installed on the frame. A cutting device for processing an easy-tear opening on the seal of the semi-fluid food packaging bag is also detachably provided on the frame, which not only achieves the easy-tear effect of the semi-fluid food packaging bag, but also does not cause adverse effects on the sealing strength and aesthetics of the semi-fluid food packaging bag.

[0005] In summary, the existing tearing mechanism has many disadvantages. For example, there is no separate longitudinal tearing and cutting mechanism, which makes it impossible to produce some bag types that require a separate longitudinal tearing. Secondly, the combination mechanism for simultaneously piercing the longitudinal and transverse tearing is single and fixed, and it is easy for the longitudinal tearing edge to be missing, and the piercing cut is only pierced on one side of the bag.

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0030] Example 1

[0031] A longitudinal sealing and tearing mechanism based on a continuous multi-row strip bag device comprises a driving mechanism 1, a frame body 2, and a cutting mechanism 3. The driving mechanism 1 is arranged on one side of the frame body 2 and is rotatably connected to the cutting mechanism 3. The cutting mechanism 3 is rotatably connected in the frame body 2. The cutting mechanism 3 comprises a cutter shaft 31 and a cutter module 32. The cutter module 32 is provided with a plurality of cutter modules on the cutter shaft 31. The cutter module 32 comprises a cutter die 321 and a connecting block 322. The cutter die 321 is connected to the connecting block 322. The cutter modules 32 are provided with a suitable number on the cutter shaft 31 according to actual working requirements, and the cutter die 321 is provided with a suitable number on the connecting block 322 according to actual working requirements. The driving mechanism 1 is a motor. The connecting position part of the cutter die 321 and the connecting block 322 can be an integral pressing block or a split pressing block, which can be determined according to actual working conditions.

[0032] The interior of the connecting block 322 is rigidly connected, the cutting die 321 is a multi-blade tool, a detection device 11 is provided on the other side of the driving mechanism 1, and the detection device 11 is fixed on the frame body 2, a cutting disc 311 is provided on one side of the cutting shaft 31, and the detection device 11 corresponds to the cutting disc 311, a bearing is provided in the connection position between the incision mechanism 3 and the frame body 2, and two cutting dies 321 are provided on the connecting block 322, but not limited to two, and it needs to be determined according to the actual working conditions, and can also be three, four, five, etc. In this scenario, the positions of the two cutting dies 321 correspond to the expansion strips The two sides of the bag, this solution is aimed at the strip bag material that is fully unfolded but not yet sealed, so the openings on both sides can be merged into a unified tear position after subsequent sealing, and the multi-blade tool can open several tearings to facilitate multi-point opening when tearing. In addition, the point that is focused on protecting in this solution is the independent longitudinal sealing tearing mechanism. Therefore, other technical features, such as the knife roller 100 that controls the direction of the roll film and corresponds to the cutting action of the knife die 321, are all existing technologies and are not repeated in this solution. In addition to the knife roller 100, the cutting action of the knife die 321 can also be applied to other structures that can realize the cutting action.

[0033] Example 2

[0034] Based on the fact that the other technical features mentioned above remain unchanged, the interior of the connecting block 322 is pneumatically connected, which makes the front and rear ends of the connecting block 322 pneumatically connected. The knife mold 321 has a certain pressure when completing the cutting action and has a slight elasticity, which extends the service life of the blade.

[0035] Example 3

[0036] Based on the condition that the other technical features mentioned above remain unchanged, the connection block 322 is internally connected by a spring, which makes the front end and the rear end of the connection block 322 elastically connected, and the cutting die 321 also has an elastic cutting action when completing the cutting action, thereby extending the service life of the blade.

[0037] Example 4

[0038] Based on the fact that the other technical features mentioned above remain unchanged, the cutting die 321 is a single-edged cutting tool, and the cutting die 321 can be adjusted and switched according to actual conditions.

[0039] Example 5

[0040] Based on the condition that the other technical features mentioned above remain unchanged, the cutting die 321 is provided on the connecting block 322. By adjusting the actual working distance between the connecting blocks 322, it is possible to achieve a one-cut cut after the longitudinal sealing position of the strip bag is sealed and pressed together, and it is also possible to achieve incisions on both sides after the strip bag is fully unfolded.

[0041] Example 6

[0042] Based on the condition that the other technical features mentioned above remain unchanged, the driving mechanism 1, in addition to adopting circular rotational motion, can also realize reciprocating motion by replacing the driving mechanism 1 with other mechanisms, and the cutting mechanism 3 realizes telescopic motion.
