Conveyed bottle clamp for filling machine

[0014] The present invention will be further described below in conjunction with the drawings and specific embodiments.

[0015] Such as figure 1 , figure 2 , image 3 As shown, the transfer bottle clamp on the filling machine includes a bottom plate 2 installed below the mounting plate 1 through a first pin 3 and a second pin 4, and a first clamp is movably provided on the first pin 3 Holding arm 5, a second clamping arm 6 is movably arranged on the second pin 4, and the clamping end of the first clamping arm 5 and the clamping end of the second clamping arm 6 can clamp the beverage in a relatively clamping manner Bottle mouth 7; on the inner side wall of the first clamping arm 5 is provided with an arc-shaped opening above the bottom plate 2, and on the inner side wall of the second clamping arm 6 is also provided with a circle above the bottom plate 2 The two arc-shaped openings are arranged opposite to each other to form a driving pin positioning hole. The driving pin 8 is movably arranged in the driving pin positioning hole. The lower end of the driving pin 8 is an inverted cone, which reduces the driving pin 8 and the bottom plate. The friction force between the upper surfaces of 2 increases the service life of the equipment; a second support column 10 is vertically arranged on the driving end of the second clamping arm 6 and a first support column 9 is vertically arranged on the bottom plate 2 , The first support column 9 and the second support column 10 are provided with a clamping arm expansion and closing elastic mechanism, the clamping arm expansion and closing elastic mechanism makes the clamping end of the first clamping arm 5 and the second clamping arm 6 The clamping end always has a tendency to clamp the mouth 7 of the beverage bottle; when the external force pushes the driving end of the second clamping arm 6 to rotate inward around the second pin 4, the clamping end of the second clamping arm 6 is synchronously driven to When the second clamping arm 6 rotates and opens, the second clamping arm 6 pushes the driving pin 8 to move forward through the corresponding arc-shaped opening, and the driving pin 8 synchronously pushes the clamping end of the first clamping arm 5 to rotate outwards and open, so that the A clamping arm 5 and a second clamping arm 6 loosen the bottle mouth 7 of the beverage bottle; when the external force exerted on the driving end of the second clamping arm 6 is removed, under the elastic force of the clamping arm opening and closing elastic mechanism , The driving end of the second clamping arm 6 rotates outwards around the second pin shaft 4, and while the clamping end of the second clamping arm 6 is synchronously driven to rotate inward, the second clamping arm 6 passes through the corresponding arc The opening pushes the driving pin 8 to move backward, and the driving pin 8 pushes the clamping end of the first clamping arm 5 to rotate inward, so that the clamping ends of the first clamping arm 5 and the second clamping arm 6 are closed together. Clamping the mouth of the beverage bottle 7; in this embodiment, the structure of the clamping arm elastic mechanism is: a first rocker 12 with a guide column 11, and a second rocker with a guide sleeve 13 14. The guide column 11 is movably arranged in the guide sleeve 13. The first rocker 12 and the second rocker 14 achieve relative telescopic movement through the cooperation of the guide column 11 and the guide sleeve 13, and the first rocker 12 and the second rocker A return spring 15 is sleeved on the rod 14. Under the action of the return spring 15, the outer end of the first rocker 12 is clamped on the first support column 9, and the outer end of the second rocker 14 is clamped on the second support. On the column 10, and the first rocker 12 and the second rocker 14 have a tendency to expand outward; this clamping arm expansion and closing elastic mechanism is not only convenient for installation and disassembly, but also improves the service life of the entire transmission bottle clamp In this embodiment, a bottle mouth retaining ring clip 16 is integrally extended on the bottom plate 2. When the first clamping arm 5 and the second clamping arm 6 clamp the beverage bottle mouth 7, the bottle mouth retaining ring clip The front end of the piece 16 is just against the mouth of the beverage bottle 7 At the same time, the front end of the bottle mouth retaining ring clip 16 just abuts the lower surface of the retaining ring 17 on the bottle mouth 7 of the beverage bottle, which not only prevents the beverage bottle from tilting during the process of placing the beverage bottle in the transfer bottle holder , It can also make the transfer bottle clamp more stable to the beverage bottle; in this embodiment, the first pin 3 between the first clamping arm 5 and the mounting plate 1, and the second clamping arm 6 and The shaft of the second pin 4 between the mounting plates 1 is fitted with a positioning column 19 respectively. The two positioning columns just press the two ends of the top surface of the driving pin 8 respectively, so as to avoid the driving pin 8 from being in the transmission bottle clamp. It is detached from the positioning hole of the driving pin during use, which improves the stability of the equipment; in this embodiment, a roller shaft is also vertically arranged on the driving end of the second clamping arm 6 equipped with the second support column 10 20. The roller shaft 20 is provided with a roller 21. In practical applications, the transfer bottle clamp is in contact with the transition wheel for pushing the second clamping arm 6 to rotate inward through the roller 21, which reduces the difference between the transfer wheel and the transition wheel. The frictional force between the equipment reduces the friction loss of the equipment and improves the overall service life of the equipment; in this embodiment, the clamping end of the first clamping arm 5 and the clamping end of the second clamping arm 6 are used The end surface of the mouth 7 of the beverage bottle is composed of several planes that can be tangent to the outer wall of the mouth 7 of the beverage bottle, so that the contact mode of the transfer bottle holder and the mouth 7 of the beverage bottle is changed from surface contact to multi-point contact. The point contact enables the transfer bottle clamp to not only firmly clamp the very regular round beverage bottle mouth 7, but also firmly clamp the irregular beverage bottle mouth.

[0016] The working principle of the present invention is as follows: when the transition wheel pushes the driving end of the second clamping arm 6 through the roller 21 to overcome the tension of the return spring 15 and rotates inwardly around the second pin 4, the second clamping arm 6 passes its corresponding The arc-shaped opening pushes the drive pin 8 forward. As the drive pin 8 moves forward, the drive pin 8 pushes the clamping end of the first clamping arm 5 around the arc-shaped opening of the first clamping arm 5. The first pin shaft 3 rotates outward to open; when the clamping end of the first clamping arm 5 and the clamping end of the second clamping arm 6 are mutually opened, the beverage bottle transfer device in the filling machine will The beverage bottle is placed in the clamping mouth formed by the clamping ends of the two clamping arms. At this time, the front end of the bottle mouth retaining ring clip 16 in the transfer bottle holder is just against the outer wall of the beverage bottle mouth 7, and the bottle mouth retaining ring The front end of the clip 16 just abuts the lower surface of the retaining ring 17 on the beverage bottle mouth 7; then the transition wheel will leave the roller 21 without applying external force to the second clamping arm 6, and the driving end of the second clamping arm 6 is at The return spring 15 rotates outwards around the second pin shaft 4 under the tension of the return spring 15 and pushes the drive pin 8 to move backward through its corresponding arc-shaped opening. As the drive pin 8 moves backward, the drive pin 8 passes through the first The arc-shaped opening of the clamping arm 5 pushes the driving end of the first clamping arm 5 to rotate outward to open, and synchronously drives the clamping end of the first clamping arm 5 to rotate inward, so that the first clamping arm 5 and The second clamping arm 6 clamps the bottle mouth 7 of the beverage bottle. Through the above operations, the operation of clamping or loosening the bottle mouth 7 of the beverage bottle by the transfer bottle clamp is completed, which not only holds the beverage bottle more firmly, but also greatly increase work productivity.
