Description

Technical Field

[0001] The invention relates to the field of beverage production equipment, and in particular to an active bottle clamping mechanism. Background Art

[0002] In the filling production, the container is transferred through the bottle clamp on the rotating disk to realize the transmission of the bottle. The bottle clamp is generally divided into active bottle clamp and passive bottle clamp. The active bottle clamp usually relies on the cooperation of the roller and the cam to realize the active opening of the two clamps, so that the bottle feeding and discharging of the bottle clamp can be realized. When the two clamps are opened, they will be linked to each other through the multi-link linkage structure between them. Setting the multi-link linkage structure will increase the processing and assembly requirements of the parts in the bottle clamp, increase the manufacturing cost, make the overall structure of the bottle clamp complicated, and reduce the service life of the bottle clamp. Summary of the invention

A compression spring is arranged between the rear parts of the two clamps. Under the action of the compression spring, the front ends of the two clamps can swing relative to each other and clamp each other; the upper cam and the lower cam are staggered in the circumferential direction of the rotating disk. When the active bottle clamp rotates driven by the rotating disk, the active bottle clamp will reciprocate onto the two cams, wherein: the upper roller will move onto the upper cam and roll along its wheel surface, and at the same time, the lower roller will move onto the lower cam and roll along its wheel surface; when the two rollers roll on their respective corresponding cams, the two cams can respectively drive the corresponding clamps to swing through the rollers rolling thereon and the driving arms corresponding to the rollers, so that the two clamps can complete the opening and closing action under the respective driving of the two cams.

[0006] Furthermore, in the aforementioned dual-drive active bottle clamp mechanism, the two cams also include a locking section located on the outer side behind the near-rest section. As the rotating disk rotates, the two rollers can simultaneously enter their respective corresponding locking sections and roll on their wheel surfaces. At this time, the two rollers will be restricted by their respective corresponding locking sections and cannot swing outward, so that the two clamps can be locked and cannot open after clamping the bottle mouth.

[0007] Furthermore, in the aforementioned dual-drive active bottle clamping mechanism, the two cams also include a return section located behind the near-rest section, the rear end of the wheel surface of the near-rest section and the front end of the wheel surface of the return section are smoothly connected, and as the rotating disk rotates, the two rollers can simultaneously enter their respective corresponding return sections and roll on their wheel surfaces. At this time, the two rollers will return at the same time and gradually swing inwards respectively, so as to reduce the impact force of the two clamps on the bottle mouth when clamping.

[0015] The present invention is further described in detail below in conjunction with specific embodiments and drawings.

[0016] like Figure 1 , Figure 2As shown, the dual-drive active bottle clamp mechanism comprises: an active bottle clamp 2 mounted on a rotating disk 1, an upper cam 3 and a lower cam 4 fixed on a frame, the structure of the active bottle clamp 2 comprises: a base 5, a left clamp 6 and a right clamp 7 are respectively arranged on the left and right sides of the base 5, the middle parts of the two clamps are respectively hinged to the base 5, so that the two clamps can swing left and right, a right driving arm 8 is arranged on the right side of the rear end of the left clamp 6, and a left driving arm 9 is arranged on the left side of the rear end of the right clamp 7, the left end of the right driving arm 8 is fixed to the rear end of the left clamp 6, and the right end of the left driving arm 9 is fixed to the rear end of the right clamp 7, the two driving arms are arranged at intervals up and down, and rollers are respectively arranged on the right end of the right driving arm 8 and the left end of the left driving arm 9, the roller located at the top is the upper roller 10, and the roller located at the lower The square roller is the lower roller 11, and a compression spring 12 is arranged between the rear parts of the two clamping pieces. Under the action of the compression spring 12, the front ends of the two clamping pieces can swing relative to each other and clamp each other; the upper cam 3 and the lower cam 4 are staggered in the circumferential direction of the rotating disk 1. When the active bottle clamp 2 rotates driven by the rotating disk 1, the active bottle clamp 2 will reciprocate to the two cams, wherein: the upper roller 10 will move to the upper cam 3 and roll along its wheel surface, and at the same time, the lower roller 11 will move to the lower cam 4 and roll along its wheel surface; when the two rollers roll on their respective corresponding cams, the two cams can respectively drive the corresponding clamping pieces to swing through the rollers rolling thereon and the driving arms corresponding to the rollers, so that the two clamping pieces can complete the opening and closing action under the respective driving of the two cams.

[0017] In this embodiment, if Figure 3 As shown, the two cams each include: a lifting section 13 and a near-resting section 14. The rear end of the wheel surface of the lifting section 13 and the front end of the wheel surface of the near-resting section 14 are smoothly butted against each other. The upper roller 10 rolls along the lifting section 13 and the near-resting section 14 on the upper cam 3 in sequence; the lower roller 11 rolls along the lifting section 13 and the near-resting section 14 on the lower cam 4 in sequence. When the active bottle clamp 2 cooperates with the two cams, the two rollers can simultaneously enter or simultaneously leave the lifting section 13 and the near-resting section 14 on the corresponding cams. When the two rollers roll on their respective corresponding lifting sections 13 at the same time, the two rollers will lift at the same time and gradually swing outward respectively. At this time, the two clamps can overcome the elastic force of the compression spring 12 and open under the drive of the respective corresponding rollers and driving arms respectively. When the two rollers roll on their respective corresponding near-rest sections 14 at the same time, the two clamps can remain open and wait for the bottle to enter. When the two rollers leave their respective corresponding near-rest sections 14 at the same time, the two clamps can clamp the bottle mouth under the action of the compression spring 12.

[0018] The two cams also include a locking section 15 located on the rear and outer side of the near-rest section 14. As the rotating disk 1 rotates, the two rollers can simultaneously enter the corresponding locking sections 15 and roll on their wheel surfaces. At this time, the two rollers are restricted by the corresponding locking sections 15 and cannot swing outward, so that the two clamps can be locked and cannot open after clamping the bottle mouth. When delivering bottles, the active bottle clamp needs to lock the two clamps through the locking section 15 to prevent the two clamps from being opened by external force after clamping the bottle.

[0019] The two cams also include: a return section 16 located behind the near-rest section 14, and the rear end of the wheel surface of the near-rest section 14 and the front end of the wheel surface of the return section 16 are smoothly connected. As the rotating disk 1 rotates, the two rollers can simultaneously enter their respective corresponding return sections 16 and roll on their wheel surfaces. At this time, the two rollers will return at the same time and gradually swing inwards respectively, thereby reducing the impact force of the two clamps on the bottle mouth under the action of the spring.

[0020] The two cams also include: a far rest section 17 located in front of the lift section 13, the rear end of the wheel surface of the far rest section 17 and the front end of the wheel surface of the lift section 13 are smoothly connected, and as the rotating disk 1 rotates, the two rollers can simultaneously enter their respective far rest sections 17 and roll on their wheel surfaces, at which time the two rollers only roll but do not drive their respective clips to move. The far rest section 17 is provided to enable the rollers to roll in advance, thereby reducing the impact force when the rollers move onto the lift section 13.

[0021] In this embodiment, a mounting column 18 is provided on the left and right sides below the base 5, respectively. The top of the mounting column 18 is fixed to the base 5, and the bottom of the mounting column 18 is fixed to the rotating disk 1, so that the base 5 can be installed on the rotating disk 1 through the two mounting columns 18. In actual production, studs are provided at both ends of the mounting column 18, and the mounting column 18 is fixed to the base 5 and the rotating disk 1 through the studs at both ends. After the active bottle clamp 2 is suspended on the rotating disk 1 through the two mounting columns 18, the assembly gap and the installation contact surface can be greatly reduced, thereby reducing the cleaning dead corners, which can better meet the customer's requirements for the cleanliness of the sterile equipment, and also reduce the number of installed parts, simplify the structure, and extend the service life.

[0022] In order to prevent the compression spring 12 from falling, positioning protrusions are respectively provided on the rear parts of the two clips, and the two ends of the compression spring 12 are respectively mounted on a positioning protrusion, so that the compression spring 12 can be positioned between the rear parts of the two clips.
