Description

TECHNICAL FIELD

[0001] The utility model belongs to production equipment technical field, concretely relates to a packing machine and bagging device thereof. BACKGROUND

[0002] In the process of using the packing machine to package products, after the products are loaded into the packaging bag, the bag opening is in an open state, the width of the bag opening in the open state is smaller than the width of the packaging bag in the initial state, and when the bag opening is sealed, the sealing mechanism moves from the outside to the middle of the bag opening, so that the two side walls of the bag opening are pressed together and sealed. Since the bag opening of the packaging bag is pressed together from the open state, the side walls of the packaging bag often cannot move sufficiently in the width direction, so that the side wall part of the bag opening is bent and folded together, so that the thickness of each part is not uniform when the bag opening is sealed, the sealing effect is poor, especially when the strength of the packaging bag is small, the side wall at the bag opening is more likely to bend and stack after being pressed, affecting the sealing effect of the packaging bag.

[0039] When the packaging machine works, the product is conveyed to the conveying device 22 through the conveying belt 21, and is banded by the banding device 31, and is further conveyed to the moisture-sensitive card placing device 32 by the conveying device 22, and is moved to the first product bagging position after the moisture-sensitive card is placed, and the first packaging bag transferring device 91 transfers the first packaging bag from the first packaging bag placing position to the first packaging bag bagging position, and the opening mechanism opens the bag opening of the packaging bag.

[0040] When the bagging device 41 is used to perform the bagging operation, the first moving mechanism 412 and the second moving mechanism 413 are located at the relatively close closed position, the first moving mechanism 412 and the second moving mechanism 413 are moved along the second horizontal direction to the abutting portions 41222, 41322 abut against the end of the product P, and the product P is gradually pushed into the packaging bag B located at the first packaging bag bagging position by the further movement of the first moving mechanism 412 or the first connecting assembly 4122 and the second moving mechanism or the second connecting assembly 4132 along the second horizontal direction (the pushing direction), and after the product P is pushed into the packaging bag, the first connecting assembly 4122 and the second connecting assembly 4132 are moved along the leaving direction opposite to the pushing direction, the abutting portions 41222, 41322 leave the bag opening of the packaging bag, and the bagging of the product P is completed.

[0041] The desiccant is then put into the first accommodating groove 41221 and / or the second accommodating groove 41321 through the desiccant placing device 71, at this time, the first push plate 4124 and the second push plate 4134 are close to the inner wall of the accommodating groove, the first closing member 4123 and the second closing member 4133 are also accommodated in the opening, the first push rod 41223 pushes the first push plate 4124 and the first closing member 4123 to move to the opening end of the accommodating groove, at the same time, the second push rod 41323 pushes the second push plate 4134 and the second closing member 4133 to move, until the desiccant is pushed into the packaging bag B, and the packaging of the desiccant is completed, at this time, the first closing member 4123 and the second closing member 4133 are still located in the packaging bag B.

[0042] It can be understood that the packaging of the product P can be carried out at the same time as the packaging of the desiccant, that is, when the product is pushed into the packaging bag B, the desiccant has been placed in the first accommodating groove 41221 and / or the second accommodating groove 41321, after the product P is pushed into place, when the first connecting assembly 4122 and the second connecting assembly 4132 are separated, the first push rod 41223 pushes the first push plate 4124 and the first closing member 4123 to move relative to the first accommodating groove 41221, at the same time, the second push rod 41323 pushes the second push plate 4134 and the second closing member 4133 to move relative to the second accommodating groove 41321, at this time, the first push plate 4124 and the second push plate 4134 can not move or move a small distance relative to the product P and the packaging bag B, so that the desiccant is placed in the packaging bag B.

[0043] Subsequently, the driving mechanism 411 drives the first moving mechanism 412 and the second moving mechanism 413 to move away from each other, the first closing member 4123 and the second closing member 4133 contact the side wall of the bag opening of the packaging bag B, and under the action of the further movement of the first moving mechanism 412 and the second moving mechanism 413 away from each other, the bag opening is pulled to move outward, so that the upper and lower side walls of the bag opening tend to be closed, considering the strength of the packaging bag and other factors, when the packaging bag is not bent or folded during sealing, the first moving mechanism 412 and the second moving mechanism 413 stop moving away from each other, the first push rod 41223 and the second push rod 41323 are driven to drive the first closing member 4123 and the second closing member 4133 to separate from the packaging bag B, and the closing operation of the packaging bag is completed. At this time, the first sealing device 61 can be used to perform vacuumizing and sealing treatment on the packaging bag.

[0044] The product after sealing can be pushed into the second packaging bag by the second packaging device 42, the second sealing device 62 performs sealing treatment, and then the product after two packaging treatments is collected and processed by the stacking device 81. The second packaging device 42 can also have a similar structure to the first packaging device 41, or can be similar to the existing technology.

[0045] In the embodiment, the movement of the first moving mechanism and the second moving mechanism along the second horizontal direction can be completed by the overall movement of the bagging device; or the driving mechanism does not move, and the first moving mechanism and the second moving mechanism move as a whole; or the driving mechanism and the mounting assemblies of the first and second moving mechanisms do not move, and the first and second connecting assemblies move relative to the first and second mounting assemblies respectively to complete the movement.
