Technical Field

[0001] The utility model relates to the technical field of packaging machines, in particular to an M-bag clamping mechanism of a bag-feeding packaging machine. Background Art

[0002] When the M-bag packaging machine is in use, a suction cup is usually used to adsorb both sides of the M-bag, so as to control the packaging bag to open the upper opening, thereby facilitating subsequent facilities to fill items into it; and the existing Chinese patent with application number: 202121645010.2 discloses an M-type bag clamping device, including multiple groups of machine clamping units installed on the outer circumference of the packaging machine turntable, each group of machine clamping units has a left suction nozzle assembly and a right suction nozzle assembly with the same structure, characterized in that: the left suction nozzle assembly can be adjusted left and right and is arranged on the left swing seat, the right suction nozzle assembly can be adjusted left and right and is arranged on the right swing seat, the left swing seat is swung on the packaging machine turntable through the left pin shaft, and the right swing seat is swung on the packaging machine turntable through the right pin shaft, the left and right swing seats are connected to the fan-shaped teeth and form a linkage relationship through the fan-shaped teeth, and the left and right swing seats return to their positions through tension springs after swinging away from each other.

[0003] Although the above technology has the effect of adjustable spacing when in use, that is, it is convenient to adapt to the use of M bags of different widths to a certain extent, but in actual use, it only adsorbs at both ends of the M bag. When the items placed in the M bag are heavy, there is a risk of separation between the M bag body and the suction nozzle, and the suction nozzle cannot be replaced conveniently, which is not conducive to subsequent maintenance. Therefore, in order to solve the above technical problems, we proposed an M bag clamping mechanism for a bag packaging machine. Utility Model Content

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] The M bag clamping mechanism of the bag-feeding packaging machine includes a mounting frame for connecting to an external packaging machine, wherein left and right screw rods and a sliding rod are respectively installed at both ends of the mounting frame, and a matching driving motor is provided at one end of the left and right screw rods. Two linkage plates are commonly installed at both ends of the left and right screw rods and the sliding rod, and a clamping plate is connected to the upper side of the linkage plate through a stretching piece, and a plurality of suction nozzles are clamped between the linkage plate and the clamping plate. The tail end of the suction nozzle is connected to an air pipe through a quick connector, and a tooth plate is fixed in the middle of the upper surface of the linkage plate, and the upper end of the tooth plate passes through the top of the clamping plate. A driving wheel is installed inside the clamping plate corresponding to the tooth plate through a pin rod for rotation, and one end of the pin rod extends to the outside of the linkage plate and is installed with a linkage block.

[0007] Preferably, a through hole is provided on the plate body of the clamping plate, the stretching member is penetrated in the through hole, and the upper end of the stretching member extends above the through hole and is installed with a latch.

[0008] Preferably, the outer ring surface of the suction nozzle is provided with a clamping ring, and the linkage plate and the clamping plate are provided with matching clamping grooves corresponding to the clamping rings.

[0009] Preferably, guide protrusions are provided at both ends of the clamping plate, and matching guide grooves are provided on the inner sides of both ends of the linkage plate corresponding to the guide protrusions.

[0012] Preferably, the air pipes are interconnected and connected to a vacuum system on an external packaging machine, and the front side of the mounting frame is commonly connected to a crossbeam.

[0013] The M-bag clamping mechanism of the bag-feeding packaging machine proposed in the utility model has the following beneficial effects:

[0014] 1: In the utility model, each suction nozzle can be controlled to be on and off by a control valve, so that the present invention can adapt to the use of M bags of different widths, that is, in addition to the two ends of the M bag, the middle part of the M bag will also be clamped and fixed by the suction nozzle. At the same time, since the suction nozzle is clamped on the upper surface of the linkage plate by the clamping plate, even if a certain suction nozzle is damaged, the personnel first closes the control valve, and then the personnel controls the rotation of the driving wheel through the linkage block, and the driving wheel pushes the clamping plate to move upward when rotating, thereby making the clamping plate gradually move away from the linkage plate, that is, the distance between the clamping plate and the linkage plate increases, and then the suction nozzle can be directly taken out of the clamping groove of the linkage plate, and then the new suction nozzle is placed on the linkage plate, and the suction nozzle is conveniently replaced at this time. In summary, compared with the traditional scheme, the present scheme not only improves the clamping force of the mechanism on the M bag, thereby reducing the phenomenon of accidental falling of the M bag during object filling, but also facilitates the replacement of the suction nozzle, thereby facilitating maintenance.

DETAILED DESCRIPTION

[0023] 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.

[0024] Example 1

[0025] Reference Figure 1-6The M bag clamping mechanism of the bag-feeding packaging machine includes a mounting frame 1 for connecting with an external packaging machine, and left and right screw rods 2 and a sliding rod 3 are respectively installed at both ends of the mounting frame 1. A matching driving motor 4 is provided at one end of the left and right screw rods 2. Two linkage plates 5 are commonly installed at both ends of the left and right screw rods 2 and the sliding rod 3. The upper side of the linkage plate 5 is connected with a clamping plate 7 through a stretching member 6. A plurality of suction nozzles 8 are clamped between the linkage plate 5 and the clamping plate 7. The tail end of the suction nozzle 8 is connected with an air pipe 10 through a quick connector 9. A tooth plate 11 is fixed to the middle part of the upper surface of the linkage plate 5. The upper end of the tooth plate 11 penetrates to the top of the clamping plate 7. The inner part of the clamping plate 7 is corresponding to the tooth plate 11 and is rotatably installed with a driving wheel 12 through a pin rod. One end of the pin rod extends to the outside of the linkage plate 5 and is installed with a linkage block 13.

[0026] Example 2

[0027] Reference Figure 1-6 , when other parts are the same as those in Example 1, the difference between this embodiment and Example 1 is that:

[0028] A through hole is provided on the plate body of the clamping plate 7, and the stretching member 6 is penetrated in the through hole. The upper end of the stretching member 6 extends to the top of the through hole and is installed with a latch 14. The setting of the through hole is convenient for accommodating the stretching member 6, and the stretching member 6 is a common elastic component, such as an elastic rope, an elastic band, a tension spring, etc., which can be selected as appropriate, and the setting of the latch 14 is convenient for replacing the stretching member 6. A clamping ring 15 is provided on the outer ring surface of the suction nozzle 8, and the linkage plate 5 and the clamping plate 7 corresponding to the clamping ring 15 are provided with matching clamping grooves. The setting of the clamping ring 15 enables the clamping plate 7 and the linkage plate 5 to clamp the suction nozzle 8 more stably. Guide protrusions are provided at both ends of the clamping plate 7, and the inner sides of the two ends of the linkage plate 5 are provided with matching guide grooves corresponding to the guide protrusions. The setting of the guide groove and the guide protrusion enables the clamping plate 7 to remain stable when moving up and down, and the clamping ring 15 can be stably and accurately clamped.

[0029] A control valve 16 is provided between the suction nozzle 8 and the quick connector 9. The control valve 16 is a manual valve. The setting of the control valve 16 facilitates the on-off control of the suction nozzle 8, that is, it is convenient to adapt to the use of M bags of different widths; the cross-section of the linkage block 13 is hexagonal, and the linkage block 13 is located at one side of the tail end of the suction nozzle 8. The setting of the linkage block 13 facilitates personnel to rotate the driving wheel 12 through an external wrench; the air pipes 10 are interconnected and connected to the vacuum system of the external packaging machine, and the front side of the mounting frame 1 is commonly connected with a crossbeam 17. The setting of the crossbeam 17 improves the stability of the mounting frame 1.

[0030] Principle and advantages of use: During the use of the utility model, the end of the air pipe 10 away from the suction nozzle 8 is connected to the vacuum system of the external packaging machine or the vacuum system of the production workshop, and the mounting frame 1 is connected to the packaging machine body, that is, the packaging machine body drives the mounting frame 1 to rotate, so as to facilitate the cyclic clamping and adsorption of the M bags; and in the above process, when the M bags need to be clamped, that is, the M bags are in the process of object filling, at this time, the output end of the driving motor 4 drives the left and right screw rods 2 to rotate, and the left and right screw rods 2 push the two linkage plates 5 away from each other when they rotate, and then when the upper end of the external M bag is transported to between the linkage plates 5 by other external facilities, the driving motor 4 drives the linkage plates 5 to approach each other through the left and right screw rods 2 until the suction nozzle 8 on the inner side of the linkage plate 5 abuts against the two sides of the M bag, and then the air pipe 10 is sucked through the external vacuum system, so that the upper end of the M bag is fixed on the inner side of the linkage plate 5 under the action of the suction nozzle 8.

[0031] In the above process, when the production batch needs to be changed, that is, the width of the M bag is changed, the personnel close the redundant suction nozzles 8 by controlling the control valve 16. If the width of the M bag is small, the suction nozzles 8 at both ends of the linkage plate 5 can be closed, so that the M bag with a smaller size can also be clamped. That is, in the above process, the present solution can control the on and off of each suction nozzle 8 by controlling the control valve 16, so that the present solution can adapt to the use of M bags of different widths, that is, in addition to the two ends of the M bag, the middle part of the M bag will also be clamped and fixed by the suction nozzle 8. At the same time, Since the suction nozzle 8 is clamped on the upper surface of the linkage plate 5 by the clamping plate 7, even if one of the suction nozzles 8 is damaged, the personnel first closes the control valve 16, and then controls the driving wheel 12 to rotate through the linkage block 13. When the driving wheel 12 rotates, it pushes the clamping plate 7 to move upward, thereby making the clamping plate 7 gradually move away from the linkage plate 5, that is, the distance between the clamping plate 7 and the linkage plate 5 increases, and then the suction nozzle 8 can be directly taken out from the clamping groove of the linkage plate 5, and then a new suction nozzle 8 is placed on the linkage plate 5, and the convenient replacement of the suction nozzle 8 is completed.

[0032] It should be further explained that the setting of the through hole is convenient for accommodating the stretching member 6, and the setting of the pin 14 is convenient for replacing the stretching member 6. The setting of the snap ring 15 enables the clamping plate 7 and the linkage plate 5 to clamp the suction nozzle 8 more stably. The setting of the guide groove and the guide protrusion allows the clamping plate 7 to remain stable when moving up and down, and the snap ring 15 can be clamped stably and accurately; the setting of the control valve 16 is convenient for on-off control of the suction nozzle 8, so as to adapt to the use of M bags of different widths; the setting of the linkage block 13 is convenient for personnel to rotate the driving wheel 12 through an external wrench; the front side of the mounting frame 1 is commonly connected with a crossbeam 17, and the setting of the crossbeam 17 improves the stability of the mounting frame 1.

[0033] 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.
