Technical Field

[0001] The utility model relates to packaging equipment, in particular to a food packaging nozzle module. Background Art

[0002] With the rapid development of modern machinery, machines have replaced manual labor in many fields. Rice packaging machine is one of them. Rice packaging machine packs rice according to set weight specifications (such as 5KG, 10KG, etc.), realizes production automation, reduces the labor intensity of workers and reduces production costs.

[0024] See also Figures 1 to 4 The utility model provides a food packaging nozzle module, which is used on a food packaging machine to evacuate a packaging bag 100 containing granular food. In this embodiment, the granular food is rice. The food packaging machine is also provided with two sealing strips 202 arranged opposite to each other and a driving device 201 connected to the two sealing strips 202. When vacuuming, the food packaging nozzle module extends into the packaging bag 100 containing food, and the driving device 201 drives the bag opening to be sealed and clamped.

[0025] The food packaging nozzle module includes a base plate 10, two first positioning devices 20 installed on both sides of the base plate 10, a beam 30 installed on the two first positioning devices 20, a second positioning device 50 and a guide device 40 installed on the beam 30, two slides 60 installed on the guide device 40, two suction nozzles 80 installed on the two slides 60, and a linkage device 70 connecting the two slides 60 and the second positioning device 50. The first positioning device drives the beam 30, the second positioning device 50, the guide device 40, the slide 60 and the linkage device 70 to adjust the position in the vertical direction. The second positioning device 50 drives the two slides 60 to adjust the position through the linkage device 70 and the guide device 40. During the positioning process, the two slides 60 synchronously drive the two suction nozzles 80 to move closer to or away from each other.

[0026] The bottom plate 10 has a central through-hole 11 through which the suction nozzle 80 passes. The bottom plate 10 has positioning portions 12 on either side of the through-hole 11. In this embodiment, the first positioning device 20 is a driving cylinder comprising a cylinder body 21 and a driving rod 22. The ends of the crossbeam 30 are connected to the cylinder bodies 21 of the two first positioning devices 20, and the driving rods 22 of the two first positioning devices 20 are mounted on the two positioning portions 12, respectively.

[0027] The guide device 40 includes a guide rail 41 and two guide blocks 42 installed on the guide rail 41. The guide rail 41 is installed on the front side of the beam 30 in the horizontal direction. The guide block 42 is provided with a T-shaped bar 411 extending in the horizontal direction. The guide block 42 is provided with a guide groove 421 that is wide inside and narrow outside. During assembly, the guide groove 421 on the guide block 42 is installed on the T-shaped bar 411 of the guide block 42, and the two slides 60 are respectively installed on the two guide blocks 42. The guide block 42 can be adjusted along the extension direction of the guide rail 41.

[0028] In this embodiment, the second positioning device 50 is a cylinder, including a cylinder body 51 and a driving rod (not shown in the figure). The cylinder of the second positioning device 50 is installed on the top surface of the crossbeam 30. The linkage device 70 includes a first linkage plate 71, a second linkage plate 72, a linkage rod 73 and a fixing member (not shown in the figure). The number of the second linkage plates 72 and the linkage rod 73 are both two. The first linkage plate 71 is connected to the driving rod of the second positioning device 50. The first linkage plate 71 is provided with a first connecting portion 711 bent to the top of the second positioning device 50. One end of the two second linkage plates 72 is respectively installed on the two guide blocks 42. The other end of the second linkage plate 72 is bent inward to form a second connecting portion 721, and the second connecting portion 721 extends above the crossbeam 30. The two linkage rods 73 are respectively arranged on both sides of the second positioning device 50, and the two linkage rods 73 are distributed in an "eight" shape. The two linkage rods 73 correspond to the two second linkage plates 72 respectively, wherein one end of the linkage rod 73 is installed with the second connecting portion 721 through a fixing member, and the other end of the linkage rod 73 is installed with the first connecting portion 711 through a fixing member. The angle between the linkage rod 73 and the first connecting portion 711 can be adjusted, and the angle between the linkage rod 73 and the second connecting portion 721 can also be adjusted.

[0029] During use, when it is necessary to increase the distance between the two suction nozzles 80 according to the specifications of the packaging bag 100, the second drive device 201 drives the first linkage plate 71 to adjust its position away from the second linkage plate 72. During the backward displacement of the first linkage plate 71, the linkage rod 73 applies a force to the slide 60 in the direction of movement of the first linkage plate 71. The ends of the two linkage rods 73 away from the first linkage plate 71 move closer to each other, and the two slides 60 and the suction nozzles 80 installed on the slide 60 move closer to each other.

[0030] On the contrary, when it is necessary to increase the distance between the two suction nozzles 80 according to the specifications of the packaging bag 100, the second driving device 201 drives the first linkage plate 71 to adjust toward the second linkage plate 72. During the forward displacement of the first linkage plate 71, the linkage rod 73 applies a force to the slide 60 in the direction of moving away from the first linkage plate 71. The ends of the two linkage rods 73 away from the first linkage plate 71 move away from each other, and the two slides 60 and the suction nozzles 80 installed on the slides 60 move away from each other.

[0031] The beneficial effect of the food packaging nozzle module of the present invention is that by arranging the second positioning device 50, the guide device 40, the two slides 60, the suction nozzle 80 and the linkage device 70, the linkage device 70 includes a first linkage plate 71, a second linkage plate 72, a linkage rod 73 and a fixing part. The number of the second linkage plate 72 and the linkage rod 73 are both two. The two linkage rods 73 are respectively arranged on both sides of the second positioning device 50 and are distributed in an "eight" shape. One end of the linkage rod 73 is movably installed with the first linkage plate 71 through a fixing part, and the other end of the linkage rod 73 is movably installed with the second linkage plate 72 through a fixing part. The second positioning device 50 drives the first linkage plate 71 to move forward and backward, and synchronously drives the two suction nozzles 80 to move closer to or away from each other, thereby realizing that the distance between the two suction nozzles 80 can be adjusted according to the specifications of the packaging bag 100, which is flexible and practical.

[0032] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0033] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
