[0012] Compared with the prior art, the utility model has the advantages that:

[0013] 1. In the application, after the air cylinder is started, the piston will push the end of the tensioning arm, causing the tensioning arm to expand. Then, the tension spring exerts force on the push rod, causing it to expand. The expansion of the push rod will drive the retainer to move forward, and then drive the conveying track on the track sprocket to move forward, so as to maintain the tensioning state of the conveying track.

Specific implementation

[0022] The technical scheme in the embodiments of the utility model will be clearly and completely described below with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0023] As Figure 1 , Figure 2 and Figure 3 The utility model provides a kind of technical scheme of surrounding shape beverage box track tensioning device, including equipment shell 1, equipment shell 1 is fixedly installed with track frame 4, track frame 4 is fixedly installed with track sliding groove 2, track sliding groove 2 is slidably installed with conveying track 3, tensioning mechanism 5 is installed in equipment shell 1, mounting shaft 507 is connected with air cylinder 508 and limiting mechanism 6, tensioning mechanism 5 can be tensioned conveying track 3, and limiting mechanism 6 can replace air cylinder 508 and lift up tensioning arm 501, reduce the load of air cylinder 508, prolong the service life of tensioning mechanism 5.

[0024] As Figure 2 , Figure 3 and Figure 4As shown, the tensioning mechanism 5 includes a tensioning arm 501 rotatably mounted in the device housing 1, an installation seat 502 rotatably mounted above the tensioning arm 501, a retainer 505 slidingly mounted on the tensioning arm 501, an installation shaft 507 fixedly mounted at the lower end of the tensioning arm 501, a push rod 504 slidingly mounted on the installation seat 502, and the end of the push rod 504 rotatably mounted on the retainer 505, a tensioning spring 503 sleeved on the push rod 504, a track sprocket 506 rotatably mounted on the retainer 505, and the conveying track 3 connected to the track sprocket 506, and a positioning shaft provided in the device housing 1, and the installation seat 502 rotatably mounted in the device housing 1 through the positioning shaft.

[0025] Specifically, when the starting cylinder 508 is activated, it will start to lift the end part of the tensioning arm 501. As the end of the tensioning arm 501 is lifted, the entire tensioning arm 501 will be unfolded. After the tensioning arm 501 is completely unfolded, the tensioning spring 503 will start to play its role, which will exert force to push the push rod 504 to extend outward. Once the push rod 504 extends, it will drive the retainer 505 to move forward. During the movement of the retainer 505 forward, it will exert force to push the conveying track 3 on the track sprocket 506 to move forward. Through such consecutive actions, the conveying track 3 is kept in a tensioned state, ensuring smooth operation of the entire conveying system.

[0026] As shown in Figure 4 , Figure 5 and Figure 6 , the limiting mechanism 6 includes a support sleeve 606 rotatably mounted at the bottom of the device housing 1, a support column 604 slidingly mounted in the support sleeve 606, a slanted sliding groove 607 formed in the support column 604, a straight sliding groove 608 provided between the lower ends of the slanted sliding grooves 607, a protrusion 603 fixedly mounted on the inner wall of the support sleeve 606 and slidingly mounted in the slanted sliding groove 607, a support frame 601 rotatably mounted on the upper end of the support column 604 and rotatably mounted on the installation shaft 507, a torsion spring 602 provided between the support frame 601 and the support column 604, a control lever 605 fixedly mounted on the support column 604, a rotating groove formed in the support frame 601, and the support frame 601 rotatably mounted on the installation shaft 507 through the rotating groove.

[0027] Specifically, when the support column 604 extends, the protruding block 603 will move along the path of the inclined sliding groove 607 and finally slide into the straight sliding groove 608. This process forces the torsion spring 602 to twist. As the tensioning degree of the conveying track 3 gradually reaches a desired state, the air cylinder 508 will stop its advancing action. Once the air cylinder 508 stops working, the torsion spring 602 begins its natural resetting process. In the resetting process, the torsion spring 602 will drive the support column 604 to twist, which makes the protruding block 603 originally located in the straight sliding groove 608 slide back into the inclined sliding groove 607. Such a design limits the retracting action of the support column 604 and ensures that the tensioning arm 501 can be effectively lifted by the support column 604. In this way, the working load of the air cylinder 508 can be reduced, and in the case of air cylinder 508 failure, the tensioning state of the conveying track 3 can still be maintained to ensure the stable operation of the system.

[0028] Working principle: when in use, the air cylinder 508 can be started first. After the air cylinder 508 is started, it will lift the end of the tensioning arm 501, so that the tensioning arm 501 is unfolded. After the tensioning arm 501 is unfolded, the tensioning spring 503 will push the push rod 504 to extend, and after the push rod 504 extends, it will drive the retainer 505 to move forward, and after the retainer 505 moves forward, it will push the conveying track 3 on the track sprocket 506 to move forward, so that the conveying track 3 is kept in a tensioning state. When the air cylinder 508 extends, the support column 604 will extend, and when the support column 604 extends, the protruding block 603 will slide from the inclined sliding groove 607 into the straight sliding groove 608, and the torsion spring 602 will be forced to twist. When the conveying track 3 is tensioned to an appropriate degree, the air cylinder 508 stops working, and after the air cylinder 508 stops working, the torsion spring 602 resets. In the resetting process, the torsion spring 602 will twist the support column 604, so that the protruding block 603 slides from the straight sliding groove 608 into the inclined sliding groove 607, and the support column 604 is limited to retract, so that the support column 604 lifts the tensioning arm 501, reduces the load of the air cylinder 508, and prolongs the service life of the tensioning mechanism 5. At the same time, the control lever 605 can be used to manually rotate the support column 604 to reset the support column 604.
