DETAILED DESCRIPTION

[0037] The technical solution of the present application will be described in detail below with reference to the accompanying drawings and in combination with the implementation modes.

[0038] In a first aspect, the present application provides a packaging bag opening device, such as Figure 1-5 The packaging bag opening device includes: an equipment frame 1, an opening mechanism 2, a clamping mechanism 3 and a bag-holding mechanism 4. The opening mechanism 2, the clamping mechanism 3 and the bag-holding mechanism 4 are accommodated in the equipment frame 1, and the specific connection method can be bolted to the horizontal and vertical beams in the equipment frame, and it is only necessary to leave space for each mechanism to work, which is not limited in this application.

[0039] The bottom of the equipment frame 1 may be slightly higher than the ground, or a pulley may be further provided at the bottom of the equipment frame 1 to facilitate the user to move the equipment. The equipment frame 1 includes a placement plane 11 for placing packaging bags and providing a work platform for bag opening operations.

[0040] The opening mechanism 2 is arranged on one side of the placement plane 11 and corresponds to the opening side of the packaging bag, and is used for performing an opening operation on the opening side of the packaging bag.

[0041] The clamping mechanism 3 is arranged at both ends of the opening mechanism 2 and corresponds to the two ends of the opening side of the packaging bag, and is used for clamping the opened packaging bag at both ends of the opening side of the packaging bag.

[0042] The bag-stretching mechanism 4 is arranged on one side of the opening mechanism 2 and can be close to or away from the placement plane 11. The bag-stretching mechanism 4 can extend into the opening of the opened packaging bag to further expand and stretch the opened packaging bag, and transfer the expanded packaging bag to the next process.

[0043] In a specific embodiment, the process of the opening mechanism 2, the clamping mechanism 3 and the bag-opening mechanism 4 includes:

[0044] The opening mechanism 2 first opens the packaging bag, and then the clamping mechanisms 3 located at both ends of the opening side of the packaging bag clamp the packaging bag at the same time. After the clamping mechanism 3 clamps the opened packaging bag, the bag-stretching mechanism 4 extends into the opening of the packaging bag to further stretch the opening to a preset range, and moves the opened packaging bag to the next process.

[0045] Specifically, for the opening mechanism 2, combined with Figure 1-Figure 3 As shown, the opening mechanism 2 includes at least one suction head 21 and a telescopic arm 22 that can be vertically extended. One end of the telescopic arm 22 is connected to the suction head 21, and the other end is fixed in the device frame 1. The telescopic arm 22 is extended to drive the vertical extension of the suction head 21 to determine whether to suck the packaging bag by applying negative pressure. The telescopic arm 22 can be fixed to the crossbeam of the device frame 1 by bolts, which is not limited in this application.

[0046] Preferably, in order to effectively open the packaging bag, the opening mechanism 2 includes a lower suction head that is not higher than the placement plane and an upper suction head that is aligned with the lower suction head and can move up and down. The upper suction head located on the upper side applies negative pressure to the upper surface of the packaging bag in the placement plane 11, while the lower suction head located on the lower side applies negative pressure to the lower surface of the packaging bag in the placement plane 11. The suction heads on both sides apply force to both sides of the packaging bag at the same time, so that the packaging bag can be opened.

[0047] Preferably, the packaging bag opening device also includes: a stop positioning device 12. The stop positioning device 12 is arranged on one side of the placement plane 11 and corresponds to the opening side of the packaging bag. The stop positioning device 12 extends out of the placement plane 11 to stop the packaging bag, or retracts to a position not higher than the placement plane 11 to open the moving space of the packaging bag. Wherein, when the opening side of the packaging bag is stopped and positioned at the stop positioning device 12, the lower suction head and the upper suction head approach each other and respectively suck the lower layer and the upper layer of the opening side of the packaging bag, and then move away from each other to open the opening of the opening side of the packaging bag. At the same time, the clamping mechanism 3 clamps the packaging bag. Then, the stop positioning device 12 retracts to a position not higher than the placement plane 11 to open the moving space of the packaging bag.

[0048] In order to realize that after the packaging bag is stretched, the packaging bag can be moved to the next process while maintaining the stretched state, the packaging bag opening device in the present application also includes a moving mechanism 5. The moving mechanism 5 is a rotatable device with a rotating shaft, which can be fixed to the crossbeam of the equipment frame 1 by bolts, as long as it does not affect its rotatable function, and this application does not limit it.

[0049] The moving mechanism 5 is connected to the bag-supporting mechanism 4. The bag-supporting mechanism 4 swings around the rotating shaft of the moving mechanism 5 to approach or move away from the placement plane 11, thereby controlling the packaging bag in the bag-supporting state to move to the next process and realizing repeated operations.

[0050] Preferably, the moving mechanism 5 is also connected to the clamping mechanism 3, and the clamping mechanism 3 swings around the rotating axis of the moving mechanism 5. The clamping mechanism 3 and the bag-supporting mechanism 4 synchronously approach or move away from the placement plane 11. When the clamping mechanism 3 and the bag-supporting mechanism 4 move away from the placement plane 11, the packaging bag is transported to the next process.

[0051] Specifically, for the clamping mechanism 3 and the bag-supporting mechanism 4, Figure 2 , Figure 4 and Figure 5 As shown, the clamping mechanism 3 further includes at least one movable clamp 31 and a clamp arm 32, one end of the clamp arm 32 is connected to the clamp 31, and the other end is connected to the moving mechanism 5. The bag-opening mechanism 4 includes a bag-opening clamp 41 and a transfer rod 42. One end of the transfer rod 42 is connected to the bag-opening clamp 41, and the other end is connected to the moving mechanism 5. The transfer rod 42 and the clamp arm 32 are synchronously swung around the rotating shaft of the moving mechanism 5 under the control of the moving mechanism 5, driving the clamp 31 and the bag-opening clamp 41 to synchronously swing around the rotating shaft of the moving mechanism 5 under the control of the moving mechanism 5, and approach or move away from the placement plane 11.

[0052] In addition, the transfer rod 42 can be configured to be retractable to further adjust the swing range.

[0053] In a specific example, the operation steps of the moving mechanism 5 are as follows:

[0054] After the opening mechanism 2 has opened the packaging bag, the rotating shaft in the moving mechanism 5 rotates forward, controlling the clamp arm 32 and the clamp head 31 to approach the placement plane 11 and clamp the packaging bag. At the same time, the moving rod 42 is also driven to approach the placement plane 11, so that the bag-opening clamp 41 extends into and opens the bag mouth of the opened packaging bag; then, the rotating shaft in the moving mechanism 5 rotates reversely, controlling the clamp arm 32 and the clamp head 31 to move away from the placement plane 11 while clamping the packaging bag. At this time, the bag-opening clamp 41 is still in the packaging bag and opens the bag mouth, and is also driven away from the placement plane 11. That is, the transfer rod 42 and the clamp arm 32 act simultaneously to control the packaging bag from leaving the equipment, and move the packaging bag away from the placement plane 11 to the next process.

[0055] It is understandable that in order to ensure the consistency of the transfer of the packaging bag to the next process, the transfer rod 42 and the clamp arm 32 are synchronized when they are away from the placement plane 11.

[0056] Furthermore, since the opening size required in the next process may be different, the bag opening clamp 41 can adjust the clamping moment as needed to adjust the size of the bag opening.

[0057] Preferably, the placement plane 11 includes: an opening through hole (not marked in the figure) and a clamp opening (not marked in the figure); the opening position of the opening through hole corresponds to the position of the opening mechanism 2, and the opening mechanism 2 absorbs the packaging bag through the opening through hole; the opening position of the clamp opening corresponds to the position of the clamping mechanism 3, and the clamping mechanism 3 clamps the packaging bag through the clamp opening.

[0058] Preferably, the packaging bag opening device further includes: a control cabinet 6, which is accommodated in the device frame 1, and its specific accommodation method can be bolted, which is not limited in this application. In addition, the control cabinet 6 is electrically connected to the opening mechanism 2, the clamping mechanism 3, the bag-holding mechanism 4, and the moving mechanism 5, and is used to supply power to the opening mechanism 2, the clamping mechanism 3, the bag-holding mechanism 4, and the moving mechanism 5.

[0059] It is understandable that all the retractable, movable, swingable, rotatable and other motion modes in this application can be realized by cylinders or other similar driving devices, and this application does not limit them. In order to ensure the orderly operation of the packaging bag opening device in this application, the operation sequence, operation time, interval time, etc. of each mechanism can be set in advance as needed, and the driving control signals can be transmitted between the various mechanisms so that each process can be coordinated and operated in an orderly manner.

[0060] The packaging bag opening equipment provided in the present application includes an opening mechanism arranged on one side of the placement plane and corresponding to the opening side of the packaging bag, a clamping mechanism arranged at both ends of the opening mechanism and corresponding to the two ends of the opening side of the packaging bag, and a bag-supporting mechanism arranged on one side of the opening mechanism and can be close to or away from the placement plane, thereby realizing the automated processing of packaging bag opening, improving the bag opening efficiency, and facilitating subsequent operations on the packaging bags.

[0061] In a second aspect, the present application further provides a packaging bag supply device, which includes at least one packaging bag opening device as described in the first aspect, and the packaging bag opening device is used to provide bag opening operations to the packaging bag supply device and move the opened packages to the next process.

[0062] Among them, the packaging bag supply device can share the equipment frame 1 with the packaging bag opening device, and the equipment frame 1 can also accommodate other operating mechanisms in the packaging bag supply device, such as a stacking mechanism or a filling mechanism, etc., which is not limited in this application.

[0063] The packaging bag supply device provided in the present application utilizes the packaging bag opening device in the packaging bag supply device to quickly and automatically open the packaging bags, thereby effectively improving the operating efficiency of the packaging bags.

[0064] The preferred embodiments of the present application are described in detail above; however, the present application is not limited to the specific details in the above embodiments. Within the technical concept of the present application, a variety of simple modifications can be made to the technical solution of the present application, and these simple modifications all fall within the protection scope of the present application.

[0065] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this application will not further describe various possible combinations.

[0066] In addition, the various implementation modes of the present application may be arbitrarily combined, and as long as they do not violate the concept of the present application, they should also be regarded as the contents disclosed by the present utility model.
