[0014] The following further elaborates on the present application in detail with reference to the Figure 1-3 drawings.
[0015] An embodiment of the present application discloses a pneumatic clamping device for a grasping type packing machine. Refer to Figure 1-3, including a pneumatic chamber 11 and a seal 12. The seal 12 is threadedly sleeved at one end of the pneumatic chamber 11, which can completely seal one end of the pneumatic chamber 11. A fixing member 2 is provided at the top of the pneumatic chamber 11. The fixing member 2 is composed of a U-shaped block 21 and two bolts 22. Both inner side walls of the U-shaped block 21 are fixedly connected to the outer surface of the pneumatic chamber 11. The two bolts 22 respectively threadedly penetrate through both ends of the inner bottom wall of the U-shaped block 21, and both bolts 22 are threadedly connected to the moving rack of the external grasping type packing machine. A circular movable plug 31 is movably arranged inside the pneumatic chamber 11. The outer side wall of the circular movable plug 31 is closely fitted with the inner side wall of the pneumatic chamber 11. One side of the pneumatic chamber 11 is movably penetrated by a movable rod 32. The part of the outer side wall of the movable rod 32 in contact with the pneumatic chamber 11 is closely fitted. One end of the movable rod 32 is fixedly connected to one side of the circular movable plug 31. One end of the top and one end of the bottom of the pneumatic chamber 11 are both communicated with a connector 33. Fixing sleeves are respectively fixedly sleeved at one end of the two connectors 33 with an air inlet pipe 34 and an air extraction pipe 35. The air inlet pipe 34 and the air extraction pipe 35 are respectively communicated with the exhaust ports of two external air pumps. The other end of the bottom of the pneumatic chamber 11 is fixedly connected to a fixed rod 36. The bottom ends of the fixed rod 36 and the movable rod 32 are both fixedly connected to an arc-shaped clamping block 37. When one of the external air pumps inflates the inside of the pneumatic chamber 11 through the air inlet pipe 34, the air pressure formed by the gas inside the pneumatic chamber 11抵触 the circular movable plug 31 to drive the movable rod 32 and the arc-shaped clamping block 37 at the bottom end of the movable rod 32 to move towards the direction of the seal 12. At this time, with the mutual cooperation of the two arc-shaped clamping blocks 37, the bottle cap can be clamped and fixed. Then, the moving rack of the external grasping type packing machine drives the pneumatic chamber 11, the movable rod 32 and the two arc-shaped clamping blocks 37 to move, and the bottle can be moved. After the bottle is moved into the external packing box, when the other external air pump inflates the inside of the pneumatic chamber 11 through the air extraction pipe 35, and at the same time one of the external air pumps extracts the gas on one side of the circular movable plug 31 in the pneumatic chamber 11 through the air inlet pipe 34, at this time, the air pressure formed by the gas inside the pneumatic chamber 11抵触 the circular movable plug 31 to drive the movable rod 32 and the arc-shaped clamping block 37 at the bottom end of the movable rod 32 to move away from the direction of the seal 12. At this time, the two arc-shaped clamping blocks 37 move away from each other, and the clamping and fixing of the bottle cap can be released. Then, the bottle can be released;
[0016] Refer to Figure 1-3 It should be noted that there are some unclear expressions in the original text, such as "气动腔11内部的气体所形成的气压抵触圆形活动塞31" where "抵触" is not a very accurate description. I have tried my best to translate according to the context.One side of the movable rod 32 is fixedly connected to the circular frame 41, and one side of the fixed rod 36 is fixedly connected to the support shaft 42. The outer surface of the support shaft 42 is movably sleeved with a clamping rod 43, and the support shaft 42 can support the clamping rod 43. One end of the bottom of the clamping rod 43 is fixedly connected to a clamping block 44, and one side of the clamping block 44 is in contact with one of the inner side walls of the circular frame 41. At this time, the movable rod 32 can be locked to prevent the movable rod 32 from leaking inside the pneumatic cavity 11 during the movement of the pneumatic cavity 11, the movable rod 32 and the two arc-shaped clamping blocks 37 driven by the mobile frame of the external grabbing case packing machine, resulting in the circular movable plug 31 driving the movable rod 32 to move and releasing the bottle The clamping of the lid causes the bottle to fall, and the top of one side of the fixed rod 36 is fixedly connected to a fixed block 45, and one end of the bottom of the fixed block 45 is fixedly connected to an electric telescopic rod 46. The electric telescopic rod 46 is electrically connected to the external power supply through an external switch. When the external switch is turned on, the electric telescopic rod 46 is controlled to make the telescopic end of the electric telescopic rod 46 extend downward and contact one end of the card rod 43, so that the card rod 43 rotates counterclockwise with the support shaft 42 as the axis, so that the card block 44 can be detached from the inside of the circular frame 41. At this time, the lock on the movable rod 32 can be released, so that the movable rod 32 can be driven to move by the circular movable plug 31 of the air cap.
[0017] Reference Figure 1 and Figure 2 The sealing member 12 is composed of an internal threaded cover 121 and a hexagonal block 122. The internal threaded cover 121 is threadedly sleeved on one end of the pneumatic chamber 11, and the hexagonal block 122 is fixedly connected to one side of the internal threaded cover 121. By using an external wrench to move the hexagonal block 122 to drive the internal threaded cover 121 to rotate, the internal threaded cover 121 can be tightly sleeved on one end of the pneumatic chamber 11.
[0018] Reference Figure 3 One side of the two arc-shaped clamping blocks 37 is bonded with a rubber block 5, which can improve the protection of the bottle caps of the bottles clamped by the two arc-shaped clamping blocks 37.
[0019] The implementation principle of the pneumatic clamping device of a grabbing type case packing machine in the embodiment of the present application is as follows: when in use, the external switch is turned on to control the electric telescopic rod 46, so that the telescopic end of the electric telescopic rod 46 extends downward and contacts one end of the card rod 43, so that the card rod 43 rotates counterclockwise with the support shaft 42 as the axis, so that the card block 44 can be disengaged from the inside of the circular frame 41, and the lock of the movable rod 32 can be released at this time. At this time, when one of the external air pumps is used to inflate the inside of the pneumatic chamber 11 through the air inlet pipe 34, the air pressure formed by the gas inside the pneumatic chamber 11 contacts the circular movable plug 31, driving the movable rod 32 and the arc-shaped clamping block 37 at the bottom end of the movable rod 32 toward the seal The sealing member 12 moves in the direction of the bottle cap. At this time, the two arc-shaped clamping blocks 37 cooperate with each other to clamp and fix the bottle cap. At this time, the external switch is turned on again to control the electric telescopic rod 46, so that the telescopic end of the electric telescopic rod 46 is retracted to the inside of the electric telescopic rod 46, thereby releasing the interference with one end of the card rod 43, so that the card rod 43 rotates clockwise with the support shaft 42 as the axis. At this time, the other end of the card rod 43 drives the card block 44 to fall and get stuck in the circular frame 41, thereby locking the movable rod 32. Then, the pneumatic chamber 11, the movable rod 32 and the two arc-shaped clamping blocks 37 are driven by the mobile frame of the external grabbing cartoning machine to move, so that the bottle can be moved.
[0020] After the bottle is moved into the external packaging box, the external switch is turned on again to control the electric telescopic rod 46, so that the telescopic end of the electric telescopic rod 46 extends downward and contacts one end of the card rod 43, so that the card rod 43 rotates counterclockwise with the support shaft 42 as the axis, so that the card block 44 can be disengaged from the inside of the circular frame 41, and the lock of the movable rod 32 can be released at this time. When another external air pump inflates the inside of the pneumatic chamber 11 through the exhaust pipe 35, at the same time, one of the external air pumps extracts the gas on the side of the circular movable plug 31 in the pneumatic chamber 11 through the air inlet pipe 34, at this time, the air pressure formed by the gas inside the pneumatic chamber 11 contacts the circular movable plug 31, driving the movable rod 32 and the arc-shaped clamping block 37 at the bottom end of the movable rod 32 to move in the direction away from the sealing member 12. At this time, when the two arc-shaped clamping blocks 37 move away from each other, the bottle cap can be clamped and fixed, and then the bottle can be released.
