Description

Technical Field

[0001] The utility model relates to the technical field of packaging equipment, in particular to a packaging bag opening device. Background Art

[0002] Electronic cigarettes are electronic products that imitate cigarettes. At present, electronic cigarettes need to be placed in packaging bags after production is completed for packaging and storage. Before use, the packaging bags are usually flat and the bag mouth is closed. In most cases, the bag mouth is manually opened by manpower and the electronic cigarette is put into the bag. Referring to the electronic cigarette bag opening mechanism disclosed (announcement) No.: CN220501176U, there are also devices in the prior art that can realize automatic opening of the packaging bag, which mainly use upper and lower suction cups to clamp the two sides of the packaging bag, and pull the upper and lower suction cups away from each other. The bag opening is conducive to the subsequent automatic bagging of electronic cigarettes. However, in the process of the upper and lower suction cups moving away from each other, the two sides of the packaging bag will gradually separate. If the suction cups are too far away from each other, the bag opening of the packaging bag cannot be fully opened, which is not conducive to the subsequent bagging of electronic cigarettes. If the suction cups are too far away from each other, the surface of the packaging bag will be separated from the suction cups, destroying the vacuum adsorption between the packaging bag and the suction cups, and then making the packaging bag unable to be opened. At the same time, the suction cups need to maintain vacuum suction until the electronic cigarette bagging is completed before they can be freed up to open the next packaging bag, and continuous operation is impossible.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] As shown in the accompanying drawings, the utility model is a packaging bag opening device, comprising an opening mechanism 1, a first pushing mechanism 2 and a bag opening fixing mechanism 3. The opening mechanism 1 mainly absorbs the two sides of the packaging bag through an upper suction cup 11 and a lower suction cup 12, and makes the upper suction cup 11 and the lower suction cup 12 relatively far away from each other at the same time, so that the bag opening of the packaging bag is opened. The bag opening fixing mechanism 3 comprises a turntable 4, a plurality of support components 5 distributed in an annular manner on the front side of the turntable 4, and a second pushing mechanism 6 for pushing the support components 5. Preferably, two or four support components 5 are arranged symmetrically at the periphery of the turntable 4. The opening mechanism 1 approaches or moves away from one of the support components 5 through the first pushing mechanism 2, preferably the support component 5 located at the top or bottom of the turntable 4. The plurality of support components 5 each include two forks 51 for opening the bag opening. The two forks 51 are arranged opposite to each other and are both rotatably connected to the turntable 4. The two forks 51 can be brought close to each other under the push of the second pushing mechanism 6.

[0022] The utility model discloses a packaging bag opening device. The opening of the packaging bag is opened in advance by an opening mechanism 1, and the opening mechanism 1 and the packaging bag currently on the opening mechanism 1 are pushed to the corresponding support assembly 5 by a first pushing mechanism 2. While the first pushing mechanism 2 is pushing, the second pushing mechanism 6 pushes the support assembly 5, so that the two forks 51 on the support assembly 5 are brought closer to each other, thereby facilitating the forks 51 to enter the opening of the packaging bag on the opening mechanism 1. After the two forks 51 enter, the second pushing mechanism 6 retreats, and the two forks 51 lose the thrust of the second pushing mechanism 6 and are opened again. Open, use two forks 51 to fully open the bag opening, and at the same time, the bag opening of the packaging bag is physically opened by the fork 51, which effectively replaces the existing method of relying on vacuum suction to maintain the bag opening open, and can reduce the use cost during the process from opening the bag opening to product bagging. The first pushing mechanism 2 drives the opening mechanism 1 to retreat, so that the opening mechanism 1 continues the opening action of the next packaging bag. At the same time, the turntable 4 rotates to another empty support component 5 to align with the opening mechanism 1, so as to prepare for the next bag opening, and the support component 5 with the packaging belt is rotated to the other side by the turntable 4 to prepare for the subsequent product bagging steps, thereby realizing continuous operation.

[0023] In this embodiment, the opening mechanism 1 includes an upper suction cup 11, a lower suction cup 12 and a guide rail 13, wherein the upper suction cup 11 and the lower suction cup 12 are symmetrically arranged at both ends of the guide rail 13 and are both slidably connected to the guide rail 13, wherein the upper suction cup 11 and the lower suction cup 12 are driven simultaneously to adsorb and open both sides of the packaging bag, which belongs to the existing structure. It should be noted that the upper suction cup 11 and the lower suction cup 12 are both arranged on the same guide rail 13, and both slide on the guide rail 13, and the guide rail 13 is installed on the first pushing mechanism 2, and the first pushing mechanism 2 can adopt a power device such as a cylinder or a hydraulic cylinder that can push the guide rail 13 to move forward and backward, and the guide rail 13 is arranged on the action end of the first pushing mechanism 2, that is, the upper suction cup 11 and the lower suction cup 12 can be moved forward or backward together through the first pushing mechanism 2.

[0024] In this embodiment, the middle part of the guide rail 13 is horizontally aligned with the second pushing mechanism 6 and the support assembly 5 located at the top of the turntable 4. The support assembly 5 located at the top of the turntable 4 is arranged between the guide rail 13 and the second pushing mechanism 6 to ensure that when the guide rail 13 is pushed to the support assembly 5, the packaging bag between the upper suction cup 11 and the lower suction cup 12 can be aligned with the support assembly 5, and the second pushing mechanism 6 can push the fork 51 together, which is conducive to the fork 51 entering the bag opening. Preferably, the middle part of the guide rail 13 is driven simultaneously by the upper suction cup 11 and the lower suction cup 12, so that the packaging bag is in the middle position of the guide rail 13, which is conducive to the entry of the support assembly 5.

[0025] In this embodiment, the center of the turntable 4 is connected to a power motor 40 for driving its rotation. The support assembly 5 includes two connecting seats 52 installed on the turntable 4. The two forks 51 are respectively hinged to the two connecting seats 52 through action blocks 53. A power motor 40 is provided in the middle of the back side of the turntable 4 for driving the turntable 4 to rotate. The turntable 4 is arranged in a polygonal shape. The support assembly 5 is fixed to each side of the turntable 4 through the connecting seats 52. The power motor 40 rotates a certain angle according to the distance between adjacent support assemblies 5. As shown in the figure, the action block 53 is fixedly connected to the corresponding fork 51. The action block 53 mainly provides a pushing portion for the second pushing mechanism 6, so that the second pushing mechanism 6 can push the fork 51 closer.

[0026] Specifically, the connecting seat 52 is provided with an opening, and the second pushing mechanism 6 includes two pushing rods 60 for pushing the action block 53. The two pushing rods 60 correspond to the openings, and the pushing rods 60 are in a retracted state. When the fork 51 needs to be pushed, the pushing rods 60 extend through the opening and abut against the action block 53.

[0027] Specifically, the connecting seat 52 is provided with a fixing rod 531 which penetrates the action block 53. One end of the fixing rod 531 is fixed to the connecting seat 52, and the other end is provided with a resisting portion extending to the front of the action block 53. A spring 532 is sleeved on the fixing rod 531, and the two ends of the spring 532 are respectively abutted against the resisting portion and the action block 53. The fixing rod 531 and the spring 532 are the rebound components of the shift fork 51, which are mainly used for the automatic rebound and expansion of the shift fork 51 after being pushed together by the second pushing mechanism 6. After the second pushing mechanism 6 pushes the forks 51 to move closer to the bag opening, the second pushing mechanism 6 retracts, and the forks 51 are re-opened under the rebounding action of the spring 532, thereby fully opening the bag opening. At the same time, since the forks 51 can maintain the open state through the action of the spring 532, generally, the distance between the two forks 51 does not need to be adjusted according to the bag opening of the packaging bag. If the opening distance of the forks 51 is larger than the width of the bag opening, the adjustment effect can be achieved by installing a gasket between the connecting seat 52 and the action block 53.

[0028] In this embodiment, a bag placing rack 70 and a bag taking mechanism 80 are also included. The bag placing rack 70 is provided with a bag outlet groove 700 at the bottom. The bag taking mechanism 80 is arranged below the bag placing rack 70. The bag taking mechanism 80 includes a swing rod 801 and a bag taking suction cup 802 for sucking the bag. The bag placing rack 70 and the opening mechanism 1 are respectively arranged at the two ends of the swing range of the swing rod 801. The bag placing rack 70 is used to place stacked bags, and a bag outlet groove 700 for the bag to enter and exit is provided at the bottom thereof. One end of the swing rod 801 is a rotating end. The bag taking suction cup 802 is arranged at the other end of the swing rod 801, and the bag taking suction cup 802 faces upward and is used to suck a single bag at the bottom of the stacked bags of the bag placing rack 70. After sucking the bag, the swing rod 801 swings to align with the opening mechanism 1, even if the sucked bag is between the upper suction cup 11 and the lower suction cup 12.

[0029] In this embodiment, an entry and exit channel is formed between the two forks 51, and a third pushing mechanism 90 is arranged on the back of the turntable 4. The third pushing mechanism 90 includes a pushing rod 900 corresponding to the entry and exit channel. The entry and exit channel corresponds to the bag opening of the packaging bag, which is convenient for subsequent automated bagging. A product conveyor belt can be arranged between the third pushing mechanism 90 and the turntable 4, and after the support assembly 5 completes the opening of the bag, the turntable 4 is rotated to the corresponding position of the third pushing mechanism 90. At this time, the pushing rod 900 pushes the product through the entry and exit channel and finally enters the packaging bag.

[0030] The above embodiments are preferred embodiments of the present utility model. All structures similar to the present utility model and equivalent changes made thereto should fall within the protection scope of the present utility model.
