The driving device 2 is arranged on the frame 1; the push claw slider assembly 4 comprises a first slider 41, a second slider 42, a third slider 43, a push claw 44, a push pin 45 and a rotating pin 46; the frame 1 is provided with a linear guide 11, and a front stopper 12 and a rear stopper 13 are fixedly arranged at the front and rear ends of the linear guide 11, respectively; the first slider 41, the second slider 42 and the third slider 43 are slidably arranged on the linear guide 11, wherein the second slider 42 is arranged close to the front stopper 12, the third slider 43 is arranged close to the rear stopper 13, and the first slider 41 is located between the second slider 42 and the third slider 43. In addition, in order to improve the stability of the first slider 41, the first slider 41 may include two connected and fixed slider units.

[0035] The driving device 2 is connected to the first slider 41 through the transmission device 3 to drive the first slider 41 to perform linear reciprocating motion. The front end of the second slider 42 is detachably connected to the front blocking member 12, the front end of the first slider 41 is detachably connected to the rear end of the second slider 42, the rear end of the first slider 41 is detachably connected to the front end of the third slider 43, and the rear end of the third slider 43 is detachably connected to the rear blocking member 13; the above-mentioned pushing pin 45 is installed on the first slider 41, the rotating pin 46 is installed on the second slider 42 and the third slider 43, the pushing claw 44 is installed on the rotating pin 46, and the pushing pin 45 is used to push the pushing claw 44 to rotate around the rotating pin 46.

[0036] Specifically, the front end and rear end of the first slider 41 are respectively installed with the first connecting member and the second connecting member, the front end and rear end of the second slider 42 are respectively installed with the third connecting member and the fourth connecting member, the front end and rear end of the third slider 43 are respectively installed with the fifth connecting member and the sixth connecting member, the front blocking member 12 is installed with the seventh connecting member, and the rear blocking member 13 is installed with the eighth connecting member; the above-mentioned first connecting member and the fourth connecting member are detachably connected to correspondingly realize the detachable connection between the front end of the first slider 41 and the rear end of the second slider 42, the second connecting member and the fifth connecting member are detachably connected to correspondingly realize the detachable connection between the rear end of the first slider 41 and the front end of the third slider 43, the third connecting member and the seventh connecting member are detachably connected, and the sixth connecting member and the eighth connecting member are detachably connected.

[0037] Preferably, the first connector and the fourth connector are detachably connected by a snap-fit ​​connection or a magnetic connection. Similarly, the second connector and the fifth connector, the third connector and the seventh connector, and the sixth connector and the eighth connector may also be detachably connected by a snap-fit ​​connection or a magnetic connection.

[0038] Furthermore, when the first connector and the fourth connector are detachably connected by magnetic attraction, the first connector and the fourth connector are magnets that attract each other, and the detachable connection between the first connector and the fourth connector is achieved by adsorption or separation between the two magnets. In addition, when the first connector and the fourth connector are detachably connected by snap-fit ​​connection, the first connector is a snap-fit ​​female component and the fourth connector is a snap-fit ​​male component, or the first connector is a snap-fit ​​male component and the fourth connector is a snap-fit ​​female component, and the detachable connection between the first connector and the fourth connector is achieved by inserting the snap-fit ​​male component into the snap-fit ​​female component and separating the snap-fit ​​male component from the snap-fit ​​female component.

[0039] In the present embodiment, the first connecting member and the fourth connecting member are both magnetically attracted magnets, the second connecting member and the fifth connecting member are both magnetically attracted magnets, the third connecting member is a snap-on male member and the seventh connecting member is a snap-on female member, the sixth connecting member is a snap-on male member and the eighth connecting member is a snap-on female member; that is, in the present embodiment, magnets are installed at the front and rear ends of the first slider 41, a snap-on male member is installed at the front end of the second slider 42 and a magnet is installed at the rear end, a magnet is installed at the front end of the third slider 43 and a snap-on male member is installed at the rear end, the front blocking member 12 is installed with a snap-on female member, and the rear blocking member 13 is installed with a snap-on female member.

[0040] Furthermore, when the connection is by magnetic attraction, in some embodiments, both the first connector and the fourth connector and both the second connector and the fifth connector are magnets, and a wire is wound around each magnet. When the first connector and the fourth connector, or the second connector and the fifth connector, need to be attracted to each other, the two magnets are energized respectively so that the first connector and the fourth connector (or the second connector and the fifth connector) generate suction force, thereby making it easier for the front end of the first slider and the rear end of the second slider, or the rear end of the first slider and the front end of the third slider to be attracted to each other; when the two need to be separated, the current direction of the magnets is changed so that the first connector and the fourth connector (or the second connector and the fifth connector) generate repulsive force, thereby making it easier for the front end of the first slider and the rear end of the second slider, or the rear end of the first slider and the front end of the third slider to be separated.

[0041] In addition, in order for the first slider 41 to be smoothly disengaged from the second slider 42, the force required for the front end of the second slider 42 to be disengaged from the front stopper 12 should be greater than the force required for the front end of the first slider 41 to be disengaged from the rear end of the second slider 42; similarly, in order for the first slider 41 to be smoothly disengaged from the third slider 43, the force required for the rear end of the third slider 43 to be disengaged from the rear stopper 13 should be greater than the force required for the rear end of the first slider 41 to be disengaged from the front end of the third slider 43; therefore, corresponding to this embodiment, the force required for the snap-in male part at the front end of the second slider 42 to be disengaged from the snap-in female part of the front stopper 12 is greater than the magnetic adsorption force between the first slider 41 and the second slider 42, and the force required for the snap-in male part at the rear end of the third slider 43 to be disengaged from the snap-in female part of the rear stopper 13 is greater than the magnetic adsorption force between the first slider 41 and the third slider 43.

[0042] In this embodiment, the push claw slider assembly 4 also includes a first mounting plate 47 and a second mounting plate 48. The first mounting plate 47 is mounted on the first slider 41, and the second mounting plate 48 is mounted on the second slider 42 and the third slider 43. The bottom end of the push pin 45 is mounted on the first mounting plate 47, and the bottom end of the rotating pin 46 is mounted on the second mounting plate 48. The push claw 44 is mounted on the top end of the rotating pin 46 and the push claw 44 is located on the top surface of the second mounting plate 48. The second mounting plate 48 is provided with a first slide groove 49, and the push claw 44 is provided with a second slide groove 410. The top end of the push pin 45 passes through the first slide groove 49 and the second slide groove 410 from bottom to top. In addition, the push claw slider assembly 4 includes a plurality of push claws 44, and the plurality of push claws 44 are evenly distributed on the top surface of the second mounting plate 48. The first mounting plate 47 can be mounted on the first slider 41 by means of a locating pin or a bolt connection, and the second mounting plate 48 can also be mounted on the second slider 42 and the third slider 43 by means of a locating pin or a bolt connection.

[0043] In addition, in some embodiments, the push claw 44 is detachably arranged on the top surface of the second mounting plate 48, so that the push claws 44 of different lengths can be replaced as needed to adapt to pushing metal can lids of different sizes, that is, the larger the metal can lid, the smaller the push claw 44 needs to be replaced, and the smaller the metal can lid, the longer the push claw 44 needs to be replaced. Further, in other embodiments, the length of the push claw 44 can be telescopically arranged, so that the length of the push claw 44 can be adjusted as needed to adapt to pushing metal can lids of different sizes, that is, the larger the metal can lid, the shorter the push claw 44 needs to be, and the smaller the metal can lid, the longer the push claw 44 needs to be.

[0044] like Fig.13As shown, the push-grab 44 includes a push-grab main rod 441 detachably arranged on the top surface of the second mounting plate 48 and a push-grab support rod 442 telescopically arranged on the push-grab main rod 441. Further, a telescopic through hole 443 is arranged in the inner side of the push-grab main rod 441 away from the second mounting plate 48 along its length direction, and the push-grab support rod 442 is telescopically arranged in the telescopic through hole 443, wherein the side wall of the telescopic through hole 443 is provided with a plurality of arc-shaped receiving card holes 444 at intervals along its length direction, and the side wall of the push-grab support rod 442 is provided with an arc-shaped clamping portion 445, and the clamping portion 445 is made of elastic material, and the clamping portion can be moved to the receiving card holes 444 at different positions to be clamped as long as force is applied, so as to realize the change of the system.

[0045] In this embodiment, the driving device 2 includes a driving motor reducer 21, which is installed on the frame 1. The transmission device 3 includes a crank 31, a crank connecting rod 32, a linear bearing slider 33 and a slider connecting rod 34. The crank 31 is installed on the output shaft of the driving motor reducer 21. The crank 31 is connected to the linear bearing slider 33 through the crank connecting rod 32. The frame 1 is provided with a guide shaft 36, and the linear bearing slider 33 is slidably set on the guide shaft 36; the first slider 41 is provided with a connecting seat 411, and the linear bearing slider 33 is rigidly connected to the connecting seat 411 through the slider connecting rod 34, wherein a rigid connection refers to two connecting parts. When one part is displaced or subjected to force, the part connected to it does not displace or deform relative to this part, that is, the two parts are connected as a whole.

[0046] It can be understood that the crank 31 transmits the power of the drive motor reducer 21 to the linear bearing slider 33 through the crank connecting rod 32, so as to convert the rotational motion of the crank 31 into the linear reciprocating motion of the linear bearing slider 33, and the linear bearing slider 33 transmits the power to the first slider 41 through the slider connecting rod 34, and since the linear bearing slider 33 is rigidly connected to the connecting seat 411 of the first slider 41 through the slider connecting rod 34, the first slider 41 can also perform linear reciprocating motion on the linear guide rail 11. The transmission device 3 of this embodiment adopts multi-stage transmission, and in other embodiments, a single-stage transmission can also be adopted, which is not too limited here.

[0047] In addition, in this embodiment, there are two groups of push claw slider assemblies 4, and two slider connecting rods 34 are installed on the linear bearing slider 33, which are respectively connected to the first sliders 41 of the two groups of push claw slider assemblies 4. The two groups of push claw slider assemblies 4 are respectively located on both sides of the carrier plate 14, and a plurality of workpieces such as metal can covers are placed on the carrier plate 14 at intervals along its length direction. The push claws 44 of the two groups of push claw slider assemblies 4 act on both sides of the workpiece to transport the workpiece. In addition, as Fig.12As shown, in other embodiments, the number of push claw slider assemblies 4 can also be four groups to achieve double-station conveying operations. The crank 31 is connected to a slider mounting plate 35 through a crank connecting rod 32. The slider mounting plate 35 is provided with two linear bearing sliders 33. The slider mounting plate 35 is respectively connected to the first sliders 41 of the four groups of push claw slider assemblies 4 through four slider connecting rods 34.

[0048] The working principle of the conveying mechanism for the metal can cover of the present embodiment is described below: (1) The driving device 2 is connected to the first slider 41 through the transmission device 3 to drive the first slider 41 to perform linear reciprocating motion on the linear guide rail 11, and since the front end of the first slider 41 is detachably connected to the rear end of the second slider 42, and the rear end of the first slider 41 is detachably connected to the front end of the third slider 43, the forward and backward movement of the first slider 41 can drive the second slider 42 and the third slider 43 to perform forward and backward movement. In other words, the first slider 41 of the present invention is an active slider, while the second slider 42 and the third slider 43 are passive sliders. (2) The push pin 45 of the push claw slider assembly 4 is installed on the first slider 41 through the first mounting plate 47, and the push claw 44 is installed on the rotating pin 46. The rotating pin 46 is installed on the second slider 42 and the third slider 43 through the second mounting plate 48. Therefore, when the first slider 41 moves, the first mounting plate 47 and the push pin 45 are driven to move linearly accordingly. When the second slider 42 moves, the push claw 44 and the third slider 43 are driven to move linearly through the second mounting plate 48. When the third slider 43 moves, the push claw 44 and the second slider 42 are driven to move linearly through the second mounting plate 48. (3) The push pin 45 moves in the first slide groove 49 and the second slide groove 410, and accordingly drives the push claw 44 to rotate around the rotating pin 46, so as to realize the opening or closing of the push claw 44, that is, the opening or closing of the push claw 44 is controlled by the relative movement between the first slider 41 and the second slider 42 and the third slider 43, and the inertia force of the push claw slider assembly 4 is used and controlled to maintain the opening or closing state of the push claw 44.
