[0001] The utility model relates to the technical field of auxiliary mechanisms of packaging machines, in particular to a machine clamp adjusting mechanism of a bag feeding packaging machine. Background Art

[0002] When the bag-feeding packaging machine is in use, it is necessary to use a machine clamp adjustment mechanism to open the bag mouth of the packaging bag. The existing Chinese patent with application number: 202220882900.3 discloses a machine clamp spacing adjustment mechanism of a bag-feeding fully automatic packaging machine, including a mounting frame arranged on the packaging machine, a rotating motor arranged on the mounting frame, a double-headed screw arranged at the end of the rotating motor, a limiting guide rod symmetrically arranged in the mounting frame and parallel to the double-headed screw, and two transverse blocks symmetrically arranged on the limiting guide rod and corresponding to the double-headed screw, support rods symmetrically arranged on the sides of the transverse blocks, and pneumatic finger cylinders symmetrically arranged at the ends of the support rods.

[0003] Although the above technology can achieve the effect of adjusting the distance, i.e. opening the bag mouth, to a certain extent when in use, in actual use, when the bag is softer, the middle part of the bag tends to tilt to one side, resulting in the bag not being squeezed open by the pneumatic finger cylinders due to their close proximity, i.e., the adaptability is low; therefore, in order to solve the above technical problems, we proposed a clamp adjustment mechanism for the bag packaging machine. Utility Model Content

[0014] 1: In the utility model, the output end of the second motor drives the rotating arm to rotate, and the end of the rotating arm drives the suction nozzle to move until the suction nozzle is attached to the outer wall of the middle body wall of the packaging bag, and then the external air source is sucked, so that the packaging bag and the suction nozzle are fixedly connected under the action of negative pressure suction.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Example 1

[0024] Reference Figure 1-5 The clamp adjustment mechanism of the bag packaging machine includes a mounting base 1, one end of the mounting base 1 is provided with a first motor 2, the mounting base 1 is internally provided with a matching left-right threaded rod 3 corresponding to the rotation of the first motor 2, and both ends of the left-right threaded rod 3 are installed with a linkage plate 4, the lower end of the linkage plate 4 extends to the front side of the mounting base 1 and is slidably provided with a prompt component, the lower end of the prompt component is installed with a base 5, the middle part of the base 5 is installed with a pneumatic finger cylinder 6, the clamping ends of the pneumatic finger cylinder 6 are close to each other, and the two bases 5 are provided with a mounting plate on the side away from each other, and the upper surface of the mounting plate is provided with a second motor 7, and the lower surface of the mounting plate is connected with a rotating arm 8, the other end of the rotating arm 8 extends to the middle of the mounting base 1 and is provided with a suction nozzle 9, and the ends of the suction nozzles 9 away from each other are connected to the external air source through an air pipe.

[0025] Example 2

[0026] Reference Figure 1-5, when other parts are the same as those in Example 1, the difference between this embodiment and Example 1 is that:

[0027] The prompt component includes a plurality of linkage rods 10, a trigger plate 11, a top spring 12 and a micro switch 13. The linkage rod 10 is slidably inserted on the linkage plate 4, the lower end of the linkage rod 10 is fixedly connected to the base 5, the trigger plate 11 is fixed to the upper end of the linkage rod 10, the top spring 12 is sleeved on the upper part of the linkage rod 10, the micro switch 13 is installed on the upper surface of the mounting plate and corresponds to the trigger plate 11, and an alarm bell 14 is provided on the upper surface of the trigger plate 11, and the alarm bell 14 is connected to the micro switch 13, so that when an external packaging machine accidentally has a filling failure, such as the external packaging machine continues to fill the packaging bag with materials, the trigger plate 11 is driven to move downward under the action of the material until the trigger plate 11 triggers the micro switch 13, thereby facilitating the transmission of fault information to the outside world, so that personnel can repair the packaging machine in time.

[0028] An opening is provided at one end of the base 5 away from each other, and the pipeline of the pneumatic finger cylinder 6 extends out from the opening. The setting of the opening is convenient for the pipeline to be threaded; a counterweight block 15 is provided on the side of the base 5 away from the mounting plate, and the counterweight block 15 is connected to the base 5 by screws. The setting of the counterweight block 14 is convenient for balancing the two ends of the linkage plate 4, thereby avoiding the phenomenon that the two ends of the linkage plate 4 are damaged due to excessive uneven force; a support seat 16 is provided at the middle part of the left and right threaded rod 3 for rotation, and the support seat 16 is fixedly connected to the mounting seat 1. The setting of the support seat 16 improves the stability of the left and right threaded rod 3 when it rotates; a number of rollers are provided on both sides of the upper end of the linkage plate 4, and the mounting seat 1 is provided with matching accommodating grooves corresponding to the rollers. The setting of the rollers is convenient for improving the stability of the linkage plate 4 when it moves.

[0029] Using principle and advantages: During the use of the utility model, the mechanism is arranged in an external packaging machine, and when packaging is required, that is, when the material chamber needs to be filled into the packaging bag, the pneumatic finger cylinder 6 clamps the two ends of the packaging bag, and then as the pneumatic finger cylinders 6 approach each other, the middle bag opening of the packaging bag is squeezed against each other, and then the bag opening of the packaging bag is opened for subsequent material filling; and in the above process, when the packaging bag is too large or the texture is soft and other factors cause the bag opening of the packaging bag to be unable to be accurately opened when the pneumatic finger cylinders 6 approach each other, before the pneumatic finger cylinders 6 move, the second motor 7 is started first, and the second motor 7 The output end drives the rotating arm 8 to rotate, and the end of the rotating arm 8 drives the suction nozzle 9 to move until the suction nozzle 9 is attached to the outer wall of the middle body wall of the packaging bag, and then the external air source is sucked, so that the packaging bag and the suction nozzle 9 are fixedly connected under the action of negative pressure suction. At this time, the two pneumatic finger cylinders 6 and the suction nozzle 9 jointly fix the two ends and the middle sides of the packaging bag. Then, when the pneumatic finger cylinder 6 moves, the output end of the second motor 7 is controlled to rotate in the opposite direction, that is, the second motor 7 pulls the middle part of the packaging bag outward through the rotating arm 8 and the suction nozzle 9 until the bag opening of the packaging bag is diamond-shaped, thereby allowing the bag opening of the packaging bag to be accurately opened.

[0030] In summary, through the mutual cooperation of various components in this scheme, the proposed machine clamp adjustment mechanism can, when in use, pull the middle wall of the bag opening of the packaging bag through the rotating arm 8 and the suction nozzle 9, thereby assisting the pneumatic finger cylinder 6 to open the bag opening of the packaging bag, so that the phenomenon of the bag opening being unable to open normally will not occur when this mechanism is used.

[0031] It should be further explained that when an external packaging machine unexpectedly encounters a filling failure, such as the external packaging machine cannot stop filling materials into the packaging bag, the trigger plate 11 is driven downward by the action of the material until the trigger plate 11 triggers the micro switch 13, thereby facilitating the transmission of fault information to the outside world, so that personnel can repair the packaging machine in time; the setting of the counterweight block 14 facilitates the balancing of the two ends of the linkage plate 4, thereby avoiding the phenomenon that the two ends of the linkage plate 4 are damaged due to excessive uneven force; the setting of the support seat 16 saves effort and improves the stability of the left and right rotating threaded rod 3; the setting of the roller facilitates the improvement of the stability of the linkage plate 4 when it moves.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
