Technical Field
[0001] This utility model belongs to the field of air nozzle machine technology, specifically relating to an air nozzle machine with cylinder-driven engagement. Background Technology
[0002] Existing air nozzle machines consist of an upper housing and a lower housing. When the upper and lower housings are closed, they form a vacuum chamber. An air nozzle that extends into the bag is formed on the lower housing. When using the air nozzle machine, the upper and lower housings need to be fastened together. The fastening method is generally achieved by fastening components, such as mechanical hooks and grooves, or electromagnetically controlled magnetic plates and magnetic suction plates. Among them, the use of mechanical hooks and grooves requires manual unfastening. During use, consumers need to perform an extra operation step, which makes the use of the air nozzle machine less intelligent. In view of this, this method was developed. Utility Model Content

Detailed Implementation
[0027] To make the above-mentioned features and advantages of this utility model more apparent and understandable, specific embodiments are described below in conjunction with the accompanying drawings for detailed explanation.
[0028] Example 1
[0029] like Figures 1-9 As shown, this embodiment provides a cylinder-driven valve machine, including an upper housing 1, a lower housing 2, two driving cylinders 3, two follower claws 4, and a locking part 5.
[0030] Two drive cylinders 3 are located on both sides inside the upper housing 1 or lower housing 2 of the nozzle machine. In this embodiment, the two drive cylinders 3 are located on both sides inside the upper housing 1. The drive cylinders 3 can be hydraulic cylinders, electric cylinders, or pneumatic cylinders. Since this solution requires the use of an air pump component in the nozzle machine, a pneumatic cylinder is selected as the drive cylinder 3 in this solution in order to save manufacturing costs.
[0031] The output end of the drive cylinder 3 is hinged to the rear end of the follower hook 4. Specifically, a connecting frame 32 is provided on one side of the output end of the drive cylinder 3. The connecting frame 32 is provided with a clearance notch 322. The drive column 31 of the drive cylinder 3 and the follower hook 4 are located in the clearance notch 322. The follower hook 4 includes a hook part 41, a rotating part 42 and a hinge part 43. An installation notch is formed on the upper surface of the hinge part 43, which penetrates the front and rear side walls. The drive column 31 extends into the installation notch and is hinged. Rotating shafts are formed on both sides of the follower hook 4. The rotating shafts are located on both sides of the rotating part 42.
[0032] Preferably, the hinge portion 43 is provided with a strip-shaped hole, and the drive column 31 at the output end of the drive cylinder 3 is hinged to the strip-shaped hole.
[0033] Two mounting plates 321 are formed on the lower surface of the connecting bracket 32. The two mounting plates 321 are located on both sides of the lower opening of the clearance notch 322. A shaft hole is formed on the mounting plate 321, and the rotating shaft is located in the shaft hole. Specifically, the upper housing 1 includes a top housing and a bottom cover. The drive cylinder 3 is located in the top housing and the bottom cover. A clearance notch 13 is formed on the lower surface of the upper housing 1. The clearance notch 13 is located on the bottom cover. A protruding frame 11 is provided around the clearance notch 13 on the inward side of the bottom cover. A first semi-circular groove is formed on the upper surface of the protruding frame 11. A second semi-circular groove is formed on the lower surface of the mounting plate 321. The first semi-circular groove and the second semi-circular groove correspond to each other. After the first semi-circular groove and the second semi-circular groove are fitted together, a shaft hole is formed. This arrangement is for the convenience of installation.
[0034] Another implementation: the shaft hole can also be directly provided on the mounting plate 321, without the need to form the shaft hole through the cooperation with the convex frame 11.
[0035] Preferably, a plurality of connecting protrusions 12 are formed on the upper surface of the bottom cover. The connecting protrusions 12 and the connecting frame 32 are connected by a connector. The connecting protrusions 12 are formed with countersunk connecting holes, and the connecting frame 32 is formed with screw holes. The connector is made of screws, which are screwed into the screw holes through the countersunk connecting holes to achieve fixation.
[0036] The drive cylinder 3 has a receiving groove on the side facing the output end. A cover plate 33 is provided at the opening of the receiving groove. A reset kit 34 is provided in the receiving groove. The end of the reset kit 34 near the cover plate 33 is connected to the circumference of the drive column 31. The reset kit 34 is a spring. With this configuration, the drive column 31 is in the ejected state under normal conditions.
[0037] The locking part 5 is provided on the upper surface of the lower housing 2. The locking part 5 has a groove 51 on the side facing the follower hook 4. The side of the locking part 5 facing the direction of pushing the cylinder 3 outward is an inclined surface, which gradually slopes downward from the inside out.
[0038] Working principle: When the upper housing 1 and the lower housing 2 are not engaged, the drive cylinder 3 is pushed out by the push-out force of the reset kit 34, and the follower hook 4 is also engaged. When the upper housing 1 and the lower housing 2 are engaged, the locking part 5 extends into the clearance notch 13, and the inclined surface of the locking part 5 abuts against the hook part 41 of the follower hook 4. The hook part 41 deflects counterclockwise around the axis of rotation until the hook part 41 aligns with the slot 51 of the locking part 5. Under the push-out force of the reset kit 34, the follower hook 4 rotates clockwise, and the hook part 41 is engaged in the slot 51 to achieve the engagement of the upper housing 1 and the lower housing 2.
[0039] When the air nozzle machine finishes working and needs to be unfastened, the drive column 31 of the drive cylinder 3 retracts, the hook 41 deflects counterclockwise around the axis of rotation, and the hook 41 of the follower hook 4 disengages from the slot 51 of the locking part 5, realizing automatic unfastening. After the upper housing 1 and the lower housing 2 are separated, the drive cylinder 3 is depressurized. Under the pushing force of the reset kit 34, the drive column 31 is pushed out, and the follower hook 4 is in the fastening state.
[0040] Example 2
[0041] The difference between this embodiment and embodiment 1 is that: the drive cylinder 3 is located inside the upper housing 1, the locking part 5 is located on the lower housing 2, a clearance notch 13 is formed on the lower surface of the upper housing 1, the rotating shaft is hinged to the two side walls of the clearance notch 13, the locking part 5 is a groove, the locking part 5 is located on the upper surface of the lower housing 2, and the slot 51 is located on the inner side wall of the locking part 5. When the upper housing 1 and the lower housing 2 are closed, the drive cylinder 3 drives the hook part 41 of the follower hook 4 to extend into the locking part 5 and lock in the slot 51. That is, the locking part 5 is embedded. By adaptively changing the size of the follower hook 4, when fastening, the hook part 41 of the follower hook 4 can extend into the groove and then lock into the slot 51 on the side wall of the groove to achieve fastening. The automatic unfastening process is the same as that in embodiment 1, and will not be described again here.
