Description

Technical Field

[0001] This utility model relates to the field of folding mechanism technology, and in particular to the accordion triangle folding mechanism for bag making machines. Background Technology

[0002] Packaging bags are important packaging materials widely used in commodity circulation and sales. Packaging bag types are generally divided into three-side seal bags, back seal bags, stand-up pouches, eight-side seal bags, gusseted bags, irregularly shaped bags, spout bags, etc. Among them, the structure of gusseted bags is that the two sides of the bag body are folded inward to form a gusseted edge structure. This structure can reduce the planar projection area of ​​the bag body after unfolding by about 30%, thereby effectively reducing the planar footprint when unfolded. In the manufacturing process of gusseted bags, a folding mechanism is usually used to make the gusseted edge. The existing folding mechanism is relatively complex, inconvenient to maintain, and difficult to adjust the opening and closing angle and gap of the folding mechanism. Utility Model Content

[0003] To overcome the shortcomings of the existing problems mentioned above, this utility model provides a gusseted triangle folding mechanism for bag making machines.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a gusseted triangular folding mechanism for a bag making machine, including a fixed bracket, an mounting bracket above the fixed bracket, a conveyor belt and a slide rail between the fixed bracket and the mounting bracket, a movable part and a slider fixedly connected to the bottom of the mounting bracket, the movable part being fixedly connected to the conveyor belt, and the slider being slidably connected to the slide rail, and a folding mechanism symmetrically arranged above the fixed bracket, the folding mechanism including a fixed plate, a hollow tube sleeve welded to the outside of the fixed plate, a connecting rod driven by a motor being sleeved inside the hollow tube sleeve, and a folding plate fixedly connected to the lower section of the connecting rod. In use, the movement of the conveyor belt drives the mounting bracket to move along the direction of the slide rail, and after moving to the designated position, the motor drives the folding plate to rotate and press it onto the fixed plate.

[0005] Preferably, the fixing plate and the mounting bracket are slidably connected by an arc-shaped slider rail structure. An L-shaped connector is rotatably connected to the fixing plate. The L-shaped connector has an elongated hole and a connecting block is fitted on the L-shaped connector. A lead screw driven by an adjustable motor is installed inside the connecting block. The lead screw passes through the elongated hole. In use, the motor drives the connecting block to adjust the fixing plate along the arc-shaped slider rail structure to appropriately adjust the spacing and opening angle of the folding mechanism.

[0006] Preferably, an adjustment bracket driven by a first electric push rod is provided above the folding mechanism. A movable plate is slidably connected above the adjustment bracket via a slider rail structure. A fixing hole is provided on the movable plate. A pressure rod driven by a second electric push rod is provided below the movable plate. After the folding mechanism folds the bag, the pressure rod is pressed down to the adhesive application area under the action of the first and second electric push rods, so that the bag is better bonded.

[0007] The advantages of this utility model are that the folding mechanism has a simple structure and is easy to maintain. Furthermore, the gap and opening angle between the folding mechanisms can be adjusted appropriately by adjusting the motor, making it convenient to use. In addition, the first electric push rod and the second electric push rod press the pressure rod down on the adhesive part of the bag body, effectively improving the adhesive effect.

That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0012] like Figure 1-3The accordion-triangle folding mechanism of the bag making machine shown includes a fixed bracket 1, an mounting bracket 2 above the fixed bracket 1, a conveyor belt 3 and a slide rail 4 between the fixed bracket 1 and the mounting bracket 2, a movable part and a slider fixedly connected to the bottom of the mounting bracket 2, the movable part being fixedly connected to the conveyor belt 3, and the slider being slidably connected to the slide rail 4. A folding mechanism 5 is symmetrically arranged above the fixed bracket 2. The folding mechanism 5 includes a fixed plate 6, a hollow tube sleeve 7 welded to the outside of the fixed plate 6, and a connecting rod 9 driven by a motor 8 inside the hollow tube sleeve 7. A folding plate 10 is fixedly connected to the lower section of the connecting rod 9. In use, the conveyor belt 3 moves, causing the mounting bracket 2 to move along the direction of the slide rail 4. After moving to the designated position, the motor 8 drives the folding plate 10 to rotate and press it onto the fixed plate 6.

[0013] The fixed plate 6 and the mounting bracket 2 are slidably connected by an arc-shaped slider rail structure 11. An L-shaped connector 12 is rotatably connected to the fixed plate 6. An elongated hole 13 is opened on the L-shaped connector 12. A connecting block 14 is sleeved on the L-shaped connector 12. A lead screw 16 driven by an adjusting motor 15 is set inside the connecting block 14. The lead screw 16 passes through the elongated hole 13. In use, the adjusting motor 15 drives the connecting block 14 to move the fixed plate 6 to adjust the spacing and opening angle of the folding mechanism 5 appropriately along the arc-shaped slider rail structure 11.

[0014] Above the folding mechanism 5 is an adjusting bracket 18 driven by a first electric push rod 17. Above the adjusting bracket 18 is a movable plate 20 slidably connected by a slider rail structure 19. The movable plate 20 has a fixing hole 23. Below the movable plate 20 is a pressure rod 22 driven by a second electric push rod 21. After the folding mechanism 5 folds the bag, the pressure rod 22 is pressed down to the glue application area under the action of the first electric push rod 17 and the second electric push rod 21, so that the bag is better glued.

[0015] Specific embodiment: Before use, according to production needs, adjust the spacing and opening angle of the folding mechanism 5 by adjusting the motor 15 driving the connecting block 14 to drive the fixing plate 6 along the arc-shaped slider slide rail structure 11. During use, the external conveying mechanism conveys the glued bag to the folding mechanism 5. The conveyor belt 3 moves to drive the mounting bracket 2 to move along the slide rail 4. After moving to the working position, the motor 8 drives the folding plate 10 to rotate, folding the two sides of the bag and sticking them to the glued area in the middle. The first electric push rod 17 and the second electric push rod 21 work in sequence, so that the lower end of the pressure rod 22 presses to the glued area of ​​the bag, so that the bag is better bonded and forms an accordion triangle shape.

[0016] This design is ingenious. The folding mechanism has a simple structure that is easy to maintain. Furthermore, the gap and opening angle between the folding mechanisms can be adjusted by adjusting the motor, making it convenient to use. In addition, the first and second electric push rods press down on the adhesive joint of the bag body, effectively improving the adhesive effect.

[0017] This invention is not limited to the specific embodiments described above. This invention extends to any new feature or combination disclosed in this specification, as well as any new method or process step or combination disclosed herein.
