bottle gripping mechanism

Abstract

This utility model relates to the field of bottle processing technology and discloses a bottle clamping mechanism, including a driving device, a connecting rod device, a first gripper, and a second gripper. The connecting rod device, the first gripper, and the second gripper are mounted on the driving device. The driving device is operatively connected to the first gripper and the second gripper, and the connecting rod device is also operatively connected to the first gripper and the second gripper, enabling the first gripper and the second gripper to move synchronously closer to or further away from each other. Due to the connecting rod device, the first gripper and the second gripper can move synchronously when they approach or move away from each other. Therefore, when the first gripper and the second gripper clamp the bottle, the forces acting on both sides of the bottle are the same. This allows for a more secure gripping of the bottle, preventing the bottle from being loosely clamped.

Description

Technical Field

[0001] This utility model relates to the field of bottle processing technology, and in particular to a bottle clamping mechanism. Background Technology

[0002] In many bottled product processing fields, bottles need to be clamped and fixed when filling, flipping, or performing other processes. However, in the process of developing this utility model, the inventors discovered that the existing technology has at least the following problems: the grippers of the clamping mechanism cannot clamp the bottles synchronously, which leads to uneven clamping force and insecure clamping when holding the bottles. Utility Model Content

[0003] This invention proposes a bottle clamping mechanism to solve the technical problem of insecure bottle clamping in the prior art.

[0004] To solve the above-mentioned technical problems, this utility model proposes a bottle clamping mechanism, including a driving device, a connecting rod device, a first clamp, and a second clamp. The connecting rod device, the first clamp, and the second clamp are mounted on the driving device. The driving device is operatively connected to the first clamp and the second clamp, and the connecting rod device is operatively connected to the first clamp and the second clamp, so that the first clamp and the second clamp move closer or further away from each other synchronously.

[0005] Optionally, the linkage device includes a first link, a second link, and an intermediate link. The intermediate link is hinged to the drive device. One end of the first link is hinged to the first gripper, and the other end of the first link is hinged to one end of the intermediate link. One end of the second link is hinged to the second gripper, and the other end of the second link is hinged to the other end of the intermediate link.

[0006] Optionally, the linkage device includes a hinge shaft, which is disposed on the drive device, and the intermediate rod is hinged to the hinge shaft. The first gripper and the second gripper are respectively located at opposite ends of the drive device.

[0007] Optionally, the linkage device further includes a mounting base and a bushing. The mounting base has an installation space and is mounted on the drive device. The hinge shaft is mounted on the mounting base and located in the installation space. The bushing is sleeved on the hinge shaft and abuts against the side wall of the mounting base and the intermediate rod.

[0008] Optionally, the first connecting rod and the second connecting rod are of equal length, and the middle part of the intermediate rod is hinged to the driving device.

[0009] Optionally, the drive device includes a cylinder body, a first piston, and a second piston;

[0010] The cylinder body has a linear cylinder cavity, the middle of which is connected to an external air source. The first piston and the second piston are respectively located at both ends of the cylinder cavity. The first piston is driven to the first gripper, and the second piston is driven to the second gripper, so as to drive the first gripper and the second gripper to move closer or further apart.

[0011] Optionally, the drive device further includes a spring, which is stretched between the first gripper and the second gripper.

[0012] Optionally, the cylinder body is further provided with a linear spring mounting cavity, and the spring is located in the spring mounting cavity;

[0013] The first gripper is provided with a first spring mounting rod, and the second gripper is provided with a second spring mounting rod. The two ends of the spring are respectively attached to the first spring mounting rod and the second spring mounting rod.

[0014] Optionally, there are two spring mounting cavities, which are located on opposite sides of the cylinder cavity, and each spring mounting cavity contains a spring.

[0015] Optionally, the cylinder body has a first limiting hole and a second limiting hole at opposite ends, the first gripper passing through the first limiting hole and the second gripper passing through the second limiting hole.

[0016] Compared with existing technologies, in this invention, the driving device drives the first and second grippers to move closer or further apart. When the first and second grippers move closer together, they can grip the bottle. When the first and second grippers move further apart, they can release the bottle. Because of the linkage mechanism, the first and second grippers can move synchronously when they move closer or further apart. Therefore, when the first and second grippers grip the bottle, the forces acting on both sides of the bottle are the same. This allows for a more secure gripping of the bottle, preventing it from becoming loosely held. Attached Figure Description

[0025] Please refer to Figures 1 to 2An embodiment of this utility model proposes a bottle clamping mechanism 100, including a driving device 10, a connecting rod device 20, a first clamping jaw 30, and a second clamping jaw 40. The connecting rod device 20, the first clamping jaw 30, and the second clamping jaw 40 are mounted on the driving device 10. The driving device 10 is operatively connected to the first clamping jaw 30 and the second clamping jaw 40, and the connecting rod device 20 is operatively connected to the first clamping jaw 30 and the second clamping jaw 40, so that the first clamping jaw 30 and the second clamping jaw 40 move closer or further away from each other synchronously.

[0026] In this embodiment, the driving device 10 drives the first gripper 30 and the second gripper 40 to move closer or further apart. When the first gripper 30 and the second gripper 40 move closer together, they can grip the bottle. When the first gripper 30 and the second gripper 40 move further apart, they can release the bottle. Because of the linkage device 20, the first gripper 30 and the second gripper 40 can move synchronously when they move closer or further apart. Therefore, when the first gripper 30 and the second gripper 40 grip the bottle, the forces acting on both sides of the bottle are the same. This allows for a more secure gripping of the bottle, preventing it from becoming loosely gripped.

[0027] In one embodiment, the linkage device 20 includes a first link 21, a second link 22, and an intermediate link 23. The intermediate link 23 is hinged to the drive device 10. One end of the first link 21 is hinged to the first gripper 30, and the other end of the first link 21 is hinged to one end of the intermediate link 23. One end of the second link 22 is hinged to the second gripper 40, and the other end of the second link 22 is hinged to the other end of the intermediate link 23. Through the transmission of the first link 21, the second link 22, the intermediate link 23, etc., the first gripper 30 and the second gripper 40 can move closer to or further away from each other.

[0028] In one embodiment, the linkage device 20 includes a hinge shaft 24 disposed on the drive device 10. The intermediate rod 23 is hinged to the hinge shaft 24, and the first gripper 30 and the second gripper 40 are respectively located at opposite ends of the drive device 10. The hinge shaft 24 is used to mount the intermediate rod 23, allowing the intermediate rod 23 to rotate around the hinge shaft 24.

[0029] In one embodiment, the linkage device 20 further includes a mounting base 25 and a bushing 26. The mounting base 25 has an installation space 252 and is mounted on the drive device 10. The hinge shaft 24 is mounted on the mounting base 25 and located in the installation space 252. The bushing 26 is sleeved on the hinge shaft 24 and abuts against the side wall of the mounting base 25 and the intermediate rod 23. The mounting base 25 is used to mount the hinge shaft 24. The mounting base 25 is gantry-shaped. The hinge shaft 24 is mounted in the installation space 252. The bushing 26 is used to limit the intermediate rod 23 and prevent the intermediate rod 23 from wobbling along the axial direction of the hinge shaft 24 when it rotates relative to the hinge shaft 24.

[0030] In one embodiment, the first connecting rod 21 and the second connecting rod 22 are of equal length, and the middle part of the intermediate rod 23 is hinged to the driving device 10. This allows the first gripper 30 and the second gripper 40 to move closer or further apart synchronously. It is understood that achieving synchronous movement of the first gripper 30 and the second gripper 40 is not limited to this embodiment, and other embodiments can also be used.

[0031] In one embodiment, the driving device 10 includes a cylinder body 11, a first piston 12, and a second piston 13. The cylinder body 11 has a linear cylinder cavity 112, the middle of which is connected to an external air source. The first piston 12 and the second piston 13 are respectively located at opposite ends of the cylinder cavity 112. The first piston 12 is operatively connected to the first gripper 30, and the second piston 13 is operatively connected to the second gripper 40, thereby driving the first gripper 30 and the second gripper 40 to move closer or further apart. The cylinder cavity 112 has an air hole in its middle, and the external air source can be an air compressor. The air compressor supplies gas to the cylinder cavity 112 through the air hole, thereby controlling the first piston 12 and the second piston 13 to move closer or further apart, and consequently driving the first gripper 30 and the second gripper 40 to move closer or further apart.

[0032] In one embodiment, the drive device 10 further includes a spring (not shown) positioned between the first gripper 30 and the second gripper 40. The spring allows the first gripper 30 and the second gripper 40 to come closer together, making the gripping of the bottle more secure.

[0033] In one embodiment, the cylinder body 11 is further provided with a linear spring mounting cavity 114, and the spring is located within the spring mounting cavity 114; the first gripper 30 is provided with a first spring mounting rod 32, and the second gripper 40 is provided with a second spring mounting rod 42, with both ends of the spring respectively attached to the first spring mounting rod 32 and the second spring mounting rod 42. The first spring mounting rod 32 and the second spring mounting rod 42 are used to mount the spring and prevent the spring from falling off.

[0034] In one embodiment, there are two spring mounting cavities 114, which are located on opposite sides of the cylinder cavity 112. Each spring mounting cavity 114 contains a spring, so that the force on both sides of the first gripper 30 and the second gripper 40 is more even.

[0035] In one embodiment, the cylinder body 11 has a first limiting hole 116 and a second limiting hole 118 at opposite ends. The first gripper 30 passes through the first limiting hole 116, and the second gripper 40 passes through the second limiting hole 118. The first limiting hole 116 limits the first gripper 30, and the second limiting hole 118 limits the second gripper 40.
