It is used to spray (print) the production date, seal, shrink film, etc. on products after they are produced. According to the packaging industry, there are packaging machines for food, daily chemical products, textiles, etc.

[0003] In the prior art, when products are packaged, the outer packaging bags of the packaging machine are mostly placed manually. The manual placement of the outer packaging bags is inefficient and cannot meet the production speed of the product outer packaging equipment assembly line. Therefore, a bag taking device of the packaging machine is proposed to solve the above-mentioned drawbacks.

[0004] The existing bag taking device of the packaging machine, for example, a bag taking device of an automatic packaging machine disclosed in patent publication number CN212354554U, although the device can realize the function of automatic bag taking, still has certain disadvantages in actual use. In the bag taking device, the packaging bags are stacked and placed in the bag taking slot. When taking the bags, the pulley is driven by the motor to rotate, which plays the role of automatically conveying the packaging bags. One end of the conveyed packaging bag will be in a suspended state to facilitate the clamping structure to clamp the packaging bag. However, since one end of the packaging bag is in a suspended state, when the clamping structure has not clamped it, the suspended end of the packaging bag is easily bent and fallen, thereby affecting the smooth clamping of the packaging bag, and the practicality is insufficient. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a bag taking device for a packaging machine which can prevent the hanging end of the packaging bag from bending and falling, so that the packaging bag can be smoothly clamped and the practicality is improved.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a bag taking device of a packaging machine comprises a bag taking trough and a supporting mechanism, a plurality of groups of packaging bags are stacked on the bag taking trough, the supporting mechanism comprises a double-axis motor, the double-axis motor is fixedly mounted on the bottom end of the bag taking trough, two groups of fixing plates are symmetrically fixedly arranged at the bottom end of the bag taking trough, driving shafts are rotatably mounted on the two groups of fixing plates, and the inner ends of the two groups of driving shafts are respectively fixedly connected to the output ends on both sides of the double-axis motor, the outer ends of the two groups of driving shafts are fixedly sleeved with driving gears, transmission shafts are rotatably mounted on the front and rear ends of the bag taking trough, driven gears are fixedly sleeved on the two groups of transmission shafts, the two groups of driven gears are respectively meshed with the two groups of driving gears, supporting arms are fixedly sleeved on the two groups of transmission shafts, electric telescopic rods are fixedly mounted on the front bottoms of the two groups of supporting arms, and the output ends of the two groups of electric telescopic rods are fixedly connected with supporting plates.

[0008] Preferably, the left sides of the front and rear ends of the bag taking groove are fixedly connected with limiting plates.

[0009] Preferably, both front and rear ends of the bag taking slot are fixedly connected with L-shaped baffles, and the L-shaped baffles cover the driving gear and the driven gear.

[0010] Preferably, the top ends of the two groups of support plates are fixedly connected with anti-slip pads.

[0011] Preferably, ribs are fixedly connected between the top ends of the two groups of L-shaped baffles and the outer walls on both sides of the bag taking groove.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows: when taking the bag, the double-axis motor is first started to drive the driving shaft to rotate, and the driving shaft drives the transmission shaft to rotate through the meshing of the active gear and the driven gear, so that the transmission shaft drives the supporting arm to rotate to a horizontal state. When the left end of the packaging bag is transmitted out and is in a suspended state, the electric telescopic rod is started to push the support plate to move upward until the support plate moves to the top and contacts the packaging bag, thereby supporting the packaging bag from both sides of the bottom of the packaging bag through the support plate, and then one end of the packaging bag can be in a horizontal suspended state to wait for the clamping structure to clamp it. As the packaging bag is continuously clamped away, the height to which the electric telescopic rod pushes the support plate to move is gradually reduced, so that the support plate supports each layer of packaging bags in a horizontal suspended state, thereby avoiding the bending and falling of the suspended end of the packaging bag, so that the packaging bag can be clamped smoothly, thereby improving practicality.

When the left end of the packaging bag 2 is transmitted out and is in a suspended state, the electric telescopic rod 10 is started to push the supporting plate 11 to move upward until the supporting plate 11 moves to the top and contacts the packaging bag 2, so that the packaging bag 2 is supported from both sides of the bottom of the packaging bag 2 by the supporting plate 11, and then one end of the packaging bag 2 can be in a horizontal suspended state to wait for the clamping structure to clamp it. As the packaging bag 2 is continuously clamped away, the height to which the electric telescopic rod 10 pushes the supporting plate 11 to move is gradually reduced, so that the supporting plate 11 supports each layer of packaging bag 2 in a horizontal suspended state, thereby avoiding the bending and falling of the suspended end of the packaging bag, so that the packaging bag can be clamped smoothly, thereby improving practicality.

[0022] The left sides of the front and rear ends of the bag taking groove 1 are fixedly connected to the limiting plates 15; by setting the limiting plates 15, when the supporting arm 9 rotates to a horizontal state, the bottom end of the limiting plates 15 just contacts the top end of the supporting arm 9, thereby limiting the supporting arm 9 to ensure that the supporting arm 9 can be in a horizontal state every time it rotates.

[0023] The front and rear ends of the bag taking groove 1 are fixedly connected with L-shaped baffles 13, and the L-shaped baffles 13 cover the driving gear 6 and the driven gear 8; by setting the L-shaped baffles 13, the driving gear 6 and the driven gear 8 can be prevented from causing accidental damage to the staff during transmission.

[0024] The top ends of the two groups of support plates 11 are fixedly connected with anti-skid pads 12 ; by providing the anti-skid pads 12 , the packaging bag 2 is not likely to slip when in contact with the bottom ends of the support plates 11 .

[0025] Ribs 14 are fixedly connected between the top ends of the two groups of L-shaped baffles 13 and the outer walls of both sides of the bag taking groove 1; by providing the ribs 14, the connection between the L-shaped baffles 13 and the bag taking groove 1 can be made more firm and stable.

[0026] The bag taking device of the packaging machine of the utility model has a working principle. When taking a bag, the double-axis motor 3 is first started to drive the driving shaft 5 to rotate, and the driving shaft 5 drives the transmission shaft 7 to rotate through the meshing of the driving gear 6 and the driven gear 8, so that the transmission shaft 7 drives the supporting arm 9 to rotate to a horizontal state. When the left end of the packaging bag 2 is transmitted out and is in a suspended state, the electric telescopic rod 10 is started to push the supporting plate 11 to move upward until the supporting plate 11 moves to the top and contacts the packaging bag 2, so that the packaging bag 2 is supported from both sides of the bottom of the packaging bag 2 by the supporting plate 11, and then one end of the packaging bag 2 can be in a horizontal suspended state to wait for clamping. The holding structure is used for clamping. As the packaging bags 2 are continuously clamped and taken away, the height to which the electric telescopic rod 10 pushes the support plate 11 to move is gradually reduced, so that the support plate 11 holds each layer of packaging bags 2 in a horizontal suspended state. When not in use, the supporting arm 9 can be turned vertically. The bag taking slot 1 is quoted from a bag taking device of an automatic packaging machine disclosed in patent publication number CN212354554U, and the specific structure and working principle of how to convey and take the packaging bags 2 have been disclosed and described in detail in the cited patent, which belongs to the prior art. Therefore, the corresponding structure is not fully drawn in this application, and its working principle will not be described in detail.

[0028] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
