Description

Technical Field

[0001] The utility model relates to the technical field of creasing of three-dimensional bag machines, in particular to a bottom line creasing mechanism of a three-dimensional bag machine. Background Technique

[0002] A three-dimensional bag machine is a three-dimensional bag vacuum packaging machine. The three-dimensional bag vacuum packaging machine can vacuum package materials with a folded back-sealed vacuum composite bag to achieve the functions of anti-oxidation and anti-mildew, and can effectively extend the storage period of the packaged items.

[0003] For example, a bottom line creasing mechanism of a three-dimensional bag machine with the publication number of "CN220576729U". When personnel place the packaging bag on the placement rack and process the crease through the three-dimensional bag machine body, by embedding one end of the connecting hose away from the negative pressure pump into the fixed tube, personnel can turn on the negative pressure pump to perform negative pressure treatment on the fixed tube, thereby reducing the safety hazards brought by manual unfolding by personnel and meeting the increased work efficiency in later use. However, this device requires the staff to put the packaging bags into the device one by one. When the staff takes out one packaging bag from multiple packaging bags, other packaging bags will be taken out, resulting in the scattering of the packaging bags and the need for re-arrangement, reducing the work efficiency. At the same time, after the device adsorbs the packaging bag with a suction cup, the suction cups on both sides are rotated to unfold the bottom end of the packaging bag, and then the bottom line creasing operation is performed. During the creasing process, the packaging bag is prone to wrinkles, affecting the creasing quality of the device. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problems that the packaging bags are scattered and need to be re-arranged, reducing the work efficiency, and the packaging bags are prone to wrinkles during the creasing process, affecting the creasing quality of the device, and to propose a bottom line creasing mechanism of a three-dimensional bag machine.

[0005] To achieve the above purpose, the utility model provides the following technical solution:

The upper end of the bottom plate is fixedly connected to the first support column. An auxiliary feeding structure is arranged above the first support column. A bent plate is fixedly connected to the upper end of the bottom plate. An anti-wrinkle structure is arranged below the bent plate. A second support column is fixedly connected to the upper end of the bottom plate. A workbench is fixedly connected to the upper end of the second support column. A box body is fixedly connected to the lower end of the workbench.

[0007] Preferably, a first motor is fixedly connected to the right end of the box body. The output end of the first motor is fixedly connected to a double-headed stud. Both ends of the double-headed stud are rotatably connected to the box body through bearings.

[0009] Preferably, the auxiliary feeding structure includes a feeding box. The lower end of the feeding box is fixedly connected to a first support column. The inner wall of the feeding box is slidably connected to a pressing plate. A straight rod is fixedly connected to the left end of the pressing plate. The straight rod is slidably connected to the feeding box. A spring is sleeved on the outer wall of the straight rod. Two ends of the spring are respectively fixedly connected to the feeding box and the pressing plate. A three-dimensional bag is placed inside the feeding box. The lower end of the feeding box is fixedly connected to a first vertical plate. A third motor is fixedly connected to the left end of the first vertical plate. The output shaft of the third motor is rotatably connected to the first vertical plate through a bearing. The output end of the third motor is fixedly connected to a first connecting rod. The first connecting rod is rotatably connected to a second connecting rod through a pin shaft. The second connecting rod is movably connected to a convex block processed at the lower end of a push plate through a pin shaft. The push plate is slidably connected to the feeding box.

[0010] Preferably, the anti-crease structure includes a hydraulic cylinder. The upper end of the hydraulic cylinder is fixedly connected to a bent plate. The output end of the hydraulic cylinder is fixedly connected to a straight plate. Two second vertical plates are fixedly connected to the lower end of the straight plate. Cross bars are fixedly connected to both ends of the second vertical plates. Both ends of the two cross bars are movably connected to a rotating plate. A torsion spring is sleeved on the outer wall of the cross bar. Two ends of the torsion spring are respectively fixedly connected to the second vertical plate and the rotating plate. A second round roller is provided inside the rotating plate. Both ends of the second round roller are rotatably connected to the rotating plate through bearings.

[0011] Preferably, a bracket is fixedly connected to the upper end of the workbench. The inner wall of the bracket is movably connected to a cross plate through a bearing. A suction cup is installed inside the cross plate.

The negative pressure pump is started to make the suction cups adsorb both ends of the three-dimensional bag, and the staff can more simply put the three-dimensional bags into the device one by one, improving the working efficiency of the device.

[0014] Through the cooperation of the anti-wrinkle structure and the suction cup, the hydraulic cylinder drives the straight plate to move downward. The downward movement of the straight plate drives the second vertical plate to move downward. The downward movement of the second vertical plate drives the cross bar, the rotating plate, the torsion spring and the second round roller to move downward, and inserts the second vertical plate into the inside of the three-dimensional bag.

The rotation of the cross plate drives the suction cup to rotate. While unfolding the three-dimensional bag by moving on both sides of the second round roller box, it can prevent the three-dimensional bag from being damaged, prevent wrinkles from being generated when unfolding the bottom end of the three-dimensional bag, and improve the crease quality of the device.

[0034] Working principle:

[0035] First, the staff member moves the pressing plate 302 to the left to compress the spring 304, and then vertically places multiple three-dimensional bags 17 inside the feeding box 301 and on the right side of the pressing plate 302 (as Figure 3 ), and then releases the pressing plate 302. The elastic force of the spring 304 drives the pressing plate 302 to move to the right, making the pressing plate 302 press tightly against the three-dimensional bag 17 and the feeding box 301, preparing for the bottom line crease of the three-dimensional bag 17.

[0036] Feeding work:

[0037] Connect the external power supply of the third motor 306 and start the third motor 306 to drive the first connecting rod 307 to rotate. The rotation of the first connecting rod 307 drives the second connecting rod 308 to move. The movement of the second connecting rod 308 drives the push plate 309 to move upward, so that the upper end of the push plate 309 is inserted between the first three-dimensional bag 17 and the second three-dimensional bag 17 on the right side, and the push plate 309 continues to move upward to push out the rightmost three-dimensional bag 17, so that the staff member can take out a three-dimensional bag 17. Then the staff member takes out the pushed-out three-dimensional bag 17 and places the three-dimensional bag above the workbench 7 and between the suction cups 15 on both sides, and starts the negative pressure pump to make the suction cups 15 adsorb the two ends of the three-dimensional bag.

[0038] Bottom line crease work:

[0039] First, start the hydraulic cylinder 501 to drive the straight plate 502 to move downward. The downward movement of the straight plate 502 drives the second vertical plate 503 to move downward. The downward movement of the second vertical plate 503 drives the cross bar 504, the rotating plate 505, the torsion spring 506 and the second round roller 507 to move downward, and makes the second vertical plate 503 insert into the three-dimensional bag 17. When the second round roller 507 contacts the workbench 7, the two second round rollers 507 roll in two directions to drive the two rotating plates 505 to unfold outward. At the same time, connect the external power supply of the second motor 16 and start the second motor 16 to drive the cross plate 14 to rotate. The rotation of the cross plate 14 drives the suction cups 15 to rotate. While the second round roller 507 moves to both sides to unfold the three-dimensional bag 17, it prevents the three-dimensional bag 17 from being damaged;

[0040] When the bottom end of the three-dimensional bag 17 expands to an appropriate position, start the first motor 9 to drive the double-headed stud 10 to rotate. The rotation of the double-headed stud 10 drives the two mounting brackets 11 to approach each other. The movement of the mounting brackets 11 drives the first round roller 12 to move, so that the first round roller 12 creases the bottom line of the three-dimensional bag 17, and control the hydraulic cylinder 501 and the first motor 9 to slowly return to the initial position when the first round roller 12 is creasing, completing the bottom line crease operation of the three-dimensional bag 17. Then the staff member takes out the three-dimensional bag with the crease completed and performs the next work again.
