Finished product bundling device for bag making machine

Abstract

The present invention discloses a finished product bundling device for a bag making machine. The rubber rings output one by one by the vibration plate along the discharge channel pass through the conical top and root of the corresponding connected guide member to reach the conveying column, and are sent to the tail end of the conveying column by the conveyor belt on the upper side of the conveying column, and fall into the notch outside the tail end of the expansion rocker. The rubber ring expansion mechanism is driven by a driving component to reciprocate in the internal cavity of the conveying column. Under the action of the expansion guide cone, the tail end of the expansion rocker drives the rubber ring to expand, and at the same time, the expansion rocker approaches and surrounds the finished stack of packaging bags, and then the expansion rocker retreats and retracts to reset, and the rubber ring is sleeved on the finished stack of packaging bags. The rubber ring bundling of packaging bags is automatically completed, which improves production efficiency, and is simple, reliable, easy to maintain, and compact.

[0017] Referring to the attached drawings, a specific structure of the present invention is reflected. The finished product bundling device of the bag making machine includes a vibrating plate 1 for rubber bands 3. The vibrating plate 1 outputs the rubber bands 3 one by one along a discharge channel 2. The discharge channel 2 just allows the rubber bands 1 to lie flat and pass through.

[0018] The end of the discharge channel 2 corresponds to the connecting guide 4, and the guide 4 has a conical top, which is located below the end of the discharge channel 2 but does not contact the end of the discharge channel 2. It is better to keep a distance of 2 to 4 times the diameter of the rubber ring body (i.e., the rubber strip constituting the rubber ring body) between the two, so as to ensure that the outer side of the rubber ring 3 falls on the outer side of the conical top, and at the same time, the inner side of the rubber ring 3 can pass smoothly and accurately between the two. The ratio of the outer diameter of the conical top to the inner diameter of the rubber ring is 1 to 6: 40 to 50. It is ensured that the rubber ring 3 output at the end of the discharge channel 2 falls and is sleeved on the conical top of the guide 4.

[0019] There is an arc-shaped transition from the top of the cone to the root of the guide member 4 and it gradually expands. The root of the guide member 4 is connected to the head end of the horizontally arranged conveying column 5. The ratio of the radial dimension of the conveying column 5 to the inner ring diameter of the rubber ring 3 is 1:2-4. A conveyor belt 7 is provided on the upper side of the conveying column 5. The head end of the conveyor belt 7 is connected to the root of the guide member 4. A monitoring sensor 19 is provided at the connection between the conveyor belt 7 and the root of the guide member 4. The tail end of the conveyor belt 7 is flush with the tail end of the conveying column 5. The belt body of the conveyor belt 7 is densely covered with grooves into which the rubber ring 3 body can be embedded. Side conveyor belts 6 are provided on the left and right sides of the conveying column, and a bottom conveyor belt 8 is provided on the lower side. Ensure that the rubber ring 3 moves smoothly on the conveying column 5.

[0020] The inner cavity of the conveying column 5 is provided with a rubber ring expansion mechanism: the mechanism includes four expansion rockers 13, the head end of the expansion rockers 13 is hinged on the mobile base 10, and the expansion guide cone 18 of the fixing device is provided near the tail end of the conveying column 5. The four expansion rockers 13 are evenly distributed in the circumferential direction around the expansion guide cone 18, and the outer periphery of the four expansion rockers 13 is provided with a spring constraint ring 11. The outer side of the tail end of the expansion rocker 13 is provided with a notch 14 for the rubber ring 3 body to be embedded, and a monitoring sensor 15 is provided corresponding to the notch 14; the electric push rod 9 drives the mobile base 10 to reciprocate in the sliding sleeve 12 of the inner cavity of the conveying column 5, thereby driving the four expansion rockers 13 to move.

[0021] By adopting the above technical solution, the vibration plate 1 outputs the rubber rings 3 one by one along the discharge channel 2, and the rubber rings 3 are put on the guide member 4 and fall onto the conveyor belt 7 of the conveying column 5. The monitoring sensor 19 sends a signal after sensing the rubber ring 3, and the vibration plate 1 stops working, and the conveyor belt 7, the side conveyor belt 6 and the bottom conveyor belt 8 are started. The rubber rings 3 are mainly transported by the conveyor belt 7 to the end of the conveying column 5 and fall into the notch 14 of the expansion rocker 13. The side conveyor belt 6 and the bottom conveyor belt 8 mainly prevent the rubber ring 3 from being hung.

[0022] The monitoring sensor 15 sends a signal after sensing the rubber ring 3, and the conveyor belt 7, the side conveyor belt 6 and the bottom conveyor belt 8 stop. The electric push rod 9 starts, and the expansion rocker bar 13 is pushed toward the tail end of the conveying column 5 by the mobile base 10. Under the action of the expansion guide cone 18, the tail end of the expansion rocker bar 13 drives the rubber ring 3 to expand. At the same time, the moving expansion process makes the four expansion rocker bars 13 approach and surround the finished stack 16 of packaging bags. Then the electric push rod 9 drives the expansion rocker bar 13 to retreat, retract and reset, and the rubber ring 3 is put on the finished stack 16 of packaging bags.

[0023] Since each finished packing bag stack 16 contains a certain number of packing bags, it is necessary to wait for the bag cutting mechanism to make and cut the finished packing bag stack 16 and then send it out from the conveyor belt 17. Therefore, the strapping device is in intermittent working mode, and each time the vibration plate 1 can start working according to the signal of the bag making machine equipment (such as a counter). Work according to the above process.

[0024] The above implementation is only for the purpose of clearly illustrating the technical solution of the present invention and cannot be understood as limiting the present invention in any way. The present invention has various known substitutions or modifications in the technical field, which fall within the protection scope of the present invention without departing from the essential meaning of the present invention.
