Description

Technical Field

[0001] The utility model relates to the field of longitudinal sealing and tearing of strip bags, in particular to a synchronous 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.

[0025] 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.

[0026] Example 1

[0027] A synchronous tearing mechanism based on a continuous multi-row bag device comprises a driving mechanism 1, a mounting plate 2 and a cutting mechanism 3. The driving mechanism 1 is fixed on one side of the mounting plate 2, and the driving mechanism 1 is connected to the axis of one side of the cutting mechanism 3 through an eccentric wheel 4. The other side of the cutting mechanism 3 is connected to the axis of the mounting plate 2 through the eccentric wheel 4. The cutting mechanism 3 is provided with a plurality of groups of tool bodies 31. The tool bodies 31 comprise a cutting die 311 and a fixing seat 312. The cutting die 311 is obliquely connected to the fixing seat 312, and the cutting die 311 and the fixing seat 312 are at a 45° angle. A detection mechanism 5 is arranged on one side of the mounting plate 2, and the detection mechanism 5 corresponds to the position of the eccentric wheel 4. The mounting plate 2 is provided with bearings at positions corresponding to the eccentric wheels 4 on both sides, and the cutting mechanism 3 is provided with bearings at positions corresponding to the eccentric wheels 4 on both sides.

[0028] The cutter mechanism 3 is driven by the driving mechanism 1 by rotation and following, and the knife die 311 is installed obliquely with a certain inclination angle. According to experiments, 45° is the best for cutting. Of course, it can also be determined according to the actual running speed of the roll film strip bag. In the process of rotation and translation, the knife die 311 simultaneously generates relative movement of the X-axis and the Y-axis. The movement speed of the Y-axis is consistent with the running speed of the roll film, so the easy-to-tear opening of the longitudinal seal can be pierced independently. At this time, the form of the longitudinally sealed roll film strip bag is the longitudinal edge sealing in the form of meshing, so only one side needs to be cut. In addition, the cutting is actually a change from a point to a line, so the cut in the synchronous operation is still a straight line, among which if Figure 1 and Figure 3 The passing panel of the roll film strip bag corresponding to the cutting die 311 shown is not the invention point of this scheme. It is also only necessary to adjust the angle of the driving mechanism 1 and the cutting die 311 according to the speed. Other passing panels that do not affect the cutting action of the cutting die 311 can be used instead, so it is not repeated in this scheme.

[0030] Under the condition that other technical features remain unchanged, the shaft connecting the cutter mechanism 3 and the eccentric wheels 4 on both sides can be directly connected through a synchronous belt.

[0031] Example 3

[0032] Based on the condition that other technical features remain unchanged, the shaft connecting the cutter mechanism 3 and the eccentric wheels 4 on both sides can be directly connected through a gear set.
