Description

Technical Field

[0001] The present application relates to the technical field of packaging machines, and in particular to an automatic bag loading mechanism of a finished bag packaging machine. Background Art

[0002] With the continuous advancement of science and technology and the increasing demand of consumers for product packaging, finished bag packaging machines have become an indispensable and important tool in modern industrial production. Finished bag packaging machines are mechanical equipment specially used to automatically load products into pre-made finished bags and perform subsequent processing such as sealing and labeling. This equipment converts raw materials or semi-finished products into finished products through automated operations, and performs fast and accurate packaging to meet market demand. The operator must place the finished bags on the bag-taking part of the equipment, and then the equipment will automatically take the bags.

[0003] With respect to the above-mentioned related technologies, the inventors believe that the bag loading mechanism in the automatic packaging machine in the traditional technology is generally difficult to change the direction of bag loading to adapt to different internal structures of the packaging machine; in addition, in the process of grabbing the bags, since multiple bags are stacked on top of each other, it is easy to cause the position of the lower layer of finished bags to shift when grabbing the finished bags, which will greatly reduce the bag loading efficiency of the bag loading mechanism and there are defects. Therefore, an automatic bag loading mechanism for a finished bag packaging machine is proposed to solve the above problems.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field. Utility Model Content

[0006] The automatic bag loading mechanism of the finished bag packaging machine provided in this application adopts the following technical solution:

[0007] The automatic bag loading mechanism of a finished bag packaging machine comprises a base, a bag loading assembly and two transverse plates, two transverse bars are rotatably connected between the two transverse plates, the outer parts of the two transverse bars are slidably connected with an adjustment seat, the outer part of the base is fixedly connected with two mounting plates, the surfaces of the two transverse plates away from the transverse bars are fixedly connected with rotating shafts, and the ends of the two rotating shafts away from the transverse plates are rotatably connected with the mounting plates; the surface of the base is fixedly connected with a bag taking box with an opening at the top, and the four inner walls of the bag taking box are fixedly connected There are multiple telescopic springs, and the other ends of the multiple telescopic springs located on the same inner wall of the bag taking box are fixedly connected to the limit plate. When the stepper motor is started, it will drive the rotating shaft to rotate, and the rotation of the rotating shaft will drive the cross plate connected to the rotating shaft to rotate, thereby driving the two cross bars to rotate, so that the two rotating shafts and the two cross plates will rotate, and a stack of finished bags will be placed in the cavity surrounded by four limit plates. At this time, the outer side of the finished bag is in close contact with the inner walls of the four limit plates, thereby preventing the bottom finished bag from shifting when the upper bag assembly adsorbs the finished bag.

[0008] Preferably, the upper bag assembly includes an electric telescopic rod fixedly connected to the bottom of the adjustment seat, the output end of the electric telescopic rod is fixedly connected to a support, and a plurality of suction cups are installed at the bottom of the support. When the electric telescopic rod is started, the plurality of suction cups are moved toward the finished bags in the bag picking box and attached to the top finished bags. The suction cups generate negative pressure through an external vacuum generator, so that the plurality of suction cups adsorb the topmost finished bags. After the adsorption is completed, the electric telescopic rod drives the adsorbed finished bags to move upward.

[0009] Preferably, a stepper motor is fixedly connected to the outside of one of the mounting plates, and the output end of the stepper motor passes through the mounting plate and is fixedly connected to one of the rotating shafts through a coupling. By starting the stepper motor, the stepper motor can drive the rotating shaft connected to it to rotate.

[0010] Preferably, a control panel is installed on the outside of one of the mounting plates and close to the stepper motor, and a stepper motor controller is provided inside the stepper motor. The stepper motor controller is an electronic product that can emit a uniform pulse signal. After the signal it emits enters the stepper motor driver, it will be converted by the driver into a strong current signal required by the stepper motor to drive the stepper motor to operate. The rotation angle and rotation rate of the stepper motor can be input in advance through the control panel, and then the stepper motor controller can accurately control the stepper motor to rotate through each angle.

[0011] Preferably, the two mounting plates are both fixedly connected to the outside of the base.

[0012] In summary, this application includes the following beneficial technical effects:

[0013] 1. Start the electric telescopic rod. Under the action of the electric telescopic rod and the suction cup, the finished product bags on the top layer can be adsorbed. After the adsorption is completed, the electric telescopic rod drives the adsorbed finished product bags to move upward. When the electric telescopic rod is retracted to the shortest, the stepper motor is started. Under the action of the stepper motor, the rotating shaft and the cross plate, the two cross bars are driven to rotate. The rotation of the two cross bars drives the external adjustment seat to rotate, thereby driving the upper bag assembly to rotate, thereby changing the direction of the upper bag to adapt to different internal structures of the packaging machine. Compared with the prior art, the present application can change the direction of the upper bag after the finished product bags are adsorbed to adapt to different internal structures of the packaging machine.

[0014] 2. Place a stack of finished bags inside the cavity surrounded by four limiting plates. At this time, the outer side of the finished bags is in close contact with the inner walls of the four limiting plates, thereby preventing the bottom finished bags from shifting when the upper bag assembly adsorbs the finished bags. Compared with the prior art, the present application can prevent the bottom finished bags from shifting when the upper bag assembly adsorbs the finished bags, thereby improving the bag loading efficiency of the bag loading mechanism.

When the stepper motor 13 is started, it will drive the rotating shaft 5 to rotate. The rotation of the rotating shaft 5 will drive the horizontal plate 2 connected to the rotating shaft 5 to rotate, thereby driving the two horizontal bars 3 to rotate. Therefore, the two rotating shafts 5 and the two horizontal plates 2 will rotate, and a stack of finished bags will be placed in the cavity surrounded by the four limit plates 9. At this time, the outer side of the finished bag is in close contact with the inner walls of the four limit plates 9, thereby preventing the bottom finished bag from being offset when the upper bag assembly adsorbs the finished bag.

A plurality of suction cups 12 are installed at the bottom of the support 11. The electric telescopic rod 10 is started to make the plurality of suction cups 12 approach the direction of the finished product bags in the bag taking box 7 and fit to the top finished product bag. The suction cups 12 generate negative pressure through an external vacuum generator, so that the three suction cups 12 adsorb the top finished product bags. After the adsorption is completed, the electric telescopic rod 10 drives the adsorbed finished product bags to move upward.

The output end of the stepper motor 13 passes through the mounting plate 6 and is fixedly connected to one of the rotating shafts 5 through a coupling.

A stepper motor controller is provided inside the stepper motor 13. The stepper motor controller is an electronic product that can emit a uniform pulse signal.

[0026] The implementation principle of the automatic bag loading mechanism of a finished bag packaging machine in the embodiment of the present application is as follows: a stack of finished bags is placed in the cavity surrounded by four limit plates 9. At this time, the outer side of the finished bag is in close contact with the inner wall of the four limit plates 9, so as to avoid the bottom finished bag from being offset when the bag loading assembly adsorbs the finished bag. The electric telescopic rod 10 is started to make multiple suction cups 12 approach the direction of the finished bag in the bag taking box 7 and fit onto the top finished bag. The suction cup 12 generates negative pressure through an external vacuum generator, so that the three suction cups 12 adsorb the topmost finished bag. After the adsorption is completed, the electric telescopic rod 10 drives the adsorbed finished bag to move upward. A stepper motor controller is arranged inside the stepper motor 13. The stepper motor controller is an electronic product that can emit a uniform pulse signal. The signal it emits enters After the stepper motor driver is turned on, the driver will convert it into the strong current signal required by the stepper motor to drive the stepper motor 13 to operate. The stepper motor 13 is preferably SC42, the stepper motor controller is preferably TPC8-8TD, and the stepper motor driver is preferably XDL-542. The rotation angle and rotation rate of the stepper motor 13 can be input in advance through the control panel 14, and then the stepper motor controller can accurately control the stepper motor 13 to rotate through each angle. When the stepper motor 13 is started, it will drive the rotating shaft 5 to rotate. The rotation of the rotating shaft 5 will drive the horizontal plate 2 connected to the rotating shaft 5 to rotate, thereby driving the two horizontal bars 3 to rotate, so that the two rotating shafts 5 and the two horizontal plates 2 will rotate, thereby changing the direction of bagging, so as to adapt to different internal structures of the packaging machine.
