When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0046] The utility model proposes a packaging bag opening arrangement device. The packaging bag opening arrangement device comprises a bag opening assembly 10, a driving assembly 20, a positioning assembly 40 and an adjusting assembly 50, wherein the bag opening assembly 10 is used to grab and open the bag opening of a ton bag; the driving assembly 20 is arranged above the bag opening assembly 10; the positioning assembly 40 and the adjusting assembly 50 are arranged on the driving assembly 20 in a relative manner; wherein the driving assembly 20 is used to drive the positioning assembly 40 and the adjusting assembly 50 to move up and down, so as to adjust the heights of the positioning assembly 40 and the adjusting assembly 50 to be flush with the bag opening edge of the ton bag; the driving assembly 20 is also used to drive the positioning assembly 40 and the adjusting assembly 50 to move relative to each other, so as to adjust the bag opening of the ton bag to a preset shape.

[0047] In one embodiment, please refer to Figure 1 and Figure 3The bag opening assembly 10 is used to dock with the upstream equipment, and the upstream equipment places the ton bag on the bag opening assembly 10 through the clamping mechanism, and opens the bag mouth of the ton bag through the bag opening assembly 10. Alternatively, the ton bag can be placed on the bag opening assembly 10 manually.

[0048] The bag opening assembly 10 includes two adsorption members 11 disposed opposite to each other. The two adsorption members 11 are respectively located at two sides of the bag opening of the ton bag.

[0049] The adsorbent 11 has an air path inside, and a negative pressure hole 13 is provided on the side wall of the adsorbent 11. The negative pressure hole 13 is connected to one end of the air path, and the other end of the air path is used to connect with equipment such as a fan. The fan forms negative pressure on the air path and the negative pressure hole 13, thereby adsorbing the edges on both sides of the bag opening of the ton bag.

[0050] In addition, it is also connected to the adsorption member 11 through a third driving member 12. The third driving member 12 adopts a motor mechanism such as a cylinder, and each adsorption member 11 is connected to a corresponding third driving member 12. In the process of driving the adsorption member 11 to move, the opening and closing degree of the bag mouth of the ton bag can be adjusted. For example, when two third driving members 12 drive two adsorption members 11 to move in opposite directions, the two sides of the bag mouth of the ton bag are pulled outward, thereby expanding the bag mouth of the ton bag; otherwise, the bag mouth of the ton bag is reduced.

[0051] After the ton bag is adsorbed by the bag opening assembly 10 , the driving assembly 20 drives the positioning assembly 40 and the adjusting assembly 50 to simultaneously descend to be flush with the bag opening of the ton bag.

[0052] By adjusting the installation positions of the positioning assembly 40 and the adjusting assembly 50, one of them is located inside the bag opening of the ton bag after being lowered, and the other is located outside the bag opening of the ton bag. Thus, during the process of moving toward each other, the edge of the bag opening of the ton bag can be squeezed to adjust the shape of the bag opening of the ton bag.

[0053] In one embodiment, please refer to Figure 2 and Figure 4 The driving component 20 includes a first driving member 21, a bracket 30 and a second driving member 22. The bracket 30 is arranged on the lifting driving member, and the positioning component 40 is arranged on the bracket 30; the second driving member 22 is arranged on the bracket 30 and is located at the top or bottom of the positioning component 40, and the adjustment component 50 is arranged on the second driving member 22; the driving directions of the first driving member 21 and the second driving member 22 are perpendicular, the first driving member 21 is used to drive the bracket 30 to move up and down, and the second driving member 22 is used to drive the adjustment component 50 to move relative to the positioning component 40.

[0054] The first driving member 21 can be a cylinder, and the bracket 30 is installed on the driving end of the first driving member 21. The driving direction of the first driving member 21 is the vertical direction. The first driving member 21 drives the bracket 30 to move up and down, and drives the second driving member 22, the positioning assembly 40 and the adjustment assembly 50 to move up and down synchronously.

[0055] When the bag opening shape of the ton bag is adjusted, the driving bracket 30 is lowered so that the positioning assembly 40 and the adjustment assembly 50 are synchronously lowered to be flush with the bag opening edge of the ton bag. When the bag opening shape of the ton bag is adjusted, the driving bracket 30 is raised so that the positioning assembly 40 and the adjustment assembly 50 are separated from the bag opening edge of the ton bag to avoid obstruction when the ton bag is docked with the rear-end equipment.

[0056] The second driving member 22 can be a linear module, etc. The driving direction of the second driving member 22 is horizontal, and the adjustment component 50 is installed on the sliding seat of the linear module to realize horizontal movement.

[0057] In order to improve the shape adjustment effect, the driving direction of the second driving member 22 is set to be parallel to the adsorption member 11, so that during adjustment, the moving direction of the adjustment component 50 is parallel to the edge of the bag mouth where the ton bag is adsorbed.

[0058] In one embodiment, when the two sides of the ton bag are sucked and pulled by the suction member 11, the bag opening is usually quadrilateral. Therefore, in order to ensure that the two ends of the bag opening are symmetrical after the shape adjustment, the number of positioning components 40 is set to two, which are respectively located on both sides of the bracket 30. When the bracket 30 is lowered, the two positioning components 40 correspond to the left and right edges of the bag opening of the ton bag respectively.

[0059] It can be understood that the number of the adjustment components 50 can also be set to two, and the two adjustment components 50 are relatively arranged on the second driving member 22, and the two adjustment components 50 are arranged one-to-one with the two positioning components 40; the second driving member 22 is used to drive the adjustment component 50 and the corresponding positioning component 40 to move toward or away from each other.

[0060] The second driving member 22 may adopt a bidirectional driving cylinder, and the two adjustment assemblies 50 are respectively installed on both sides of the second driving member 22 , and the two adjustment assemblies 50 are driven to move by the second driving member 22 .

[0061] In this embodiment, the two positioning components 40 are located between the two adjustment components 50, and the two adjustment components 50 are respectively located on the left and right sides of the two positioning components 40. Therefore, when the two adjustment components 50 are driven to move toward each other by the second driving member 22, the adjustment components 50 and their corresponding positioning components 40 squeeze the edge of the bag opening of the ton bag.

[0062] In different situations, for example, if the two adjustment components 50 are respectively located between the two positioning components 40, the two adjustment components 50 are driven to move in opposite directions by the second driving member 22; or, if the adjustment component 50 is located on the left side of the corresponding positioning component 40, the two adjustment components 50 are driven to move synchronously to the right by the second driving member 22, and so on.

[0063] After the bag opening of the ton bag is opened by the bag opening assembly 10, the driving assembly 20 drives the positioning assembly 40 and the adjusting assembly 50 to move to the edge of the bag opening of the ton bag, and the bag opening of the ton bag is positioned by the positioning assembly 40 to prevent the bag opening position of the adjusting assembly 50 from shifting during the adjustment process. The adjusting assembly 50 moves toward the positioning assembly 40, thereby squeezing the edge of the bag opening of the ton bag, and adjusting it according to a preset shape to form a shape that can adapt to the back-end equipment, thereby improving the degree of automation and intelligence and reducing the workload of operators.

[0064] In one embodiment, the positioning assembly 40 includes a first connecting plate 41 and a positioning rod 42, wherein one end of the first connecting plate 41 is connected to the driving assembly 20, and the other end extends to above the bag opening assembly 10; one end of the positioning rod 42 is connected to one end of the first connecting plate 41 away from the driving assembly 20, and the other end extends downward.

[0065] The first connecting plate 41 is fixed to the bracket 30 by screws. After one end of the first connecting plate 41 is connected to the bracket 30, the other end extends to the top of the middle position of the two adsorbents 11. This ensures that the positioning rod 42 can correspond to the position of the ton bag after it is lowered.

[0066] The adjustment assembly 50 includes a second connecting plate 51 and an adjustment rod 52 . The second connecting plate 51 is disposed on the driving assembly 20 ; and the adjustment rod 52 is disposed on the second connecting plate 51 .

[0067] The positioning rod 42 and the adjusting rod 52 are in the shape of long strips, with the bottom extending downward. The positioning rod 42 and the adjusting rod 52 remain parallel, and the first connecting plate 41 and the second connecting plate 51 are spaced at a preset distance to ensure that after descending, one of the positioning rod 42 and the adjusting rod 52 extends into the inside of the ton bag, and the other end extends into the outside of the ton bag.

[0068] The adjusting rod 52 is staggered with the positioning rod 42. When the adjusting rod 52 is driven to move toward the side of the positioning rod 42, the edge of the ton bag is clamped by the positioning rod 42 and the adjusting rod 52, and the positioning rod 42 and the adjusting rod 52 are controlled to continue to move relative to each other, thereby squeezing the edge of the ton bag. After moving to the preset position, the adjusting rod 52 retreats, thereby adjusting the shape of the edge of the bag mouth of the ton bag.

[0069] In this embodiment, taking the adjustment of the bag opening edge of the ton bag to an "M" shape as an example, there are two positioning rods 42, and the two positioning rods 42 are arranged opposite to each other to form an adjustment gap 43 between the two positioning rods 42 for the adjustment assembly 50 to pass through.

[0070] The adjusting rod 52 is driven to move toward the positioning rod 42 so that the adjusting rod 52 passes through the adjusting gap 43 and squeezes the edge of the ton bag into an "M" shape.

[0071] It should be noted that the adjustment rod 52 includes a connecting part 521 and an adjusting part 522. One end of the connecting part 521 is connected to the second connecting plate 51, and the other end extends toward the side of the positioning assembly 40; one end of the adjusting part 522 is connected to one end of the connecting part 521 away from the second connecting plate 51, and the other end extends downward.

[0072] To avoid interference between the first connecting plate 41 and the second connecting plate 51 during relative movement, when the adjusting rod 52 moves toward one end of the positioning rod 42, after the adjusting portion 522 passes through the adjustment gap 43, it can still drive the second connecting plate 51 to continue moving until the entire connecting portion 521 passes through the adjustment gap 43.

[0073] In order to achieve different adjustment shapes, the length of the connecting portion 521 can be adjusted according to the preset shape. At the same time, more different shape adjustment effects can be achieved by increasing the number of positioning rods 42 and adjustment rods 52, such as adjusting to a wave shape, etc., to improve compatibility.

[0074] In one embodiment, the connecting portion 521 and the adjusting portion 522 are arranged in an "L" shape. In order to maximize the moving distance of the second connecting plate 51, the connecting portion 521 and the adjusting portion 522 are kept vertical, and the connecting portion 521 is parallel to the adsorption member 11, so that the connecting portion 521 can pass through the adjustment gap 43 to the maximum extent.

[0075] In one embodiment, a slide rail 31 may be further provided on the bracket 30 , and the two sides thereof may be fixed on the slide rail 31 to guide the bracket 30 and avoid the position of the bracket 30 from being offset during the lifting process.

[0076] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
