[0002] After the chloric acid disinfectant is prepared, it needs to be filled into empty bottles using filling equipment. Existing filling equipment often uses a direct spray method to inject the liquid into the empty bottles. The impact of the sprayed chloric acid disinfectant on the empty bottles often causes the bottles to tilt, resulting in unstable filling and unsatisfactory filling results.

[0003] In addition, existing filling machines are also equipped with bottle clamping mechanisms, which clamp empty bottles before filling to improve stability during filling. However, the existing bottle clamping mechanisms have poor flexibility during the bottle clamping process and can only accommodate bottles of the same height, resulting in poor adaptability. Utility Model Content

[0017] In order to make the purpose, technical solutions and advantages of the utility model more clearly understood, the utility model is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not intended to limit the utility model.

[0018] In order to illustrate the technical solution of the present invention, specific embodiments are provided below.

[0019] For the sake of convenience, only the parts related to the embodiments of the present invention are shown.

[0020] Combine Figure 1-2As shown, the bottle clamping mechanism for the filling machine includes a pair of optical shafts 1, a lifting seat 2 is provided on the optical shaft 1, a sleeve shaft 3 is provided in the lifting seat 2, and a sliding seat 4 and a slide 5 are sequentially sleeved on the sleeve shaft 3 from the outside to the inside. An inner and outer bottle clamping mounting plate 6 is provided between the slide 5 and the slide 4 respectively. Each bottle clamping mounting plate 6 is provided with a group of bottle clamping blocks 7, and the two groups of bottle clamping blocks 7 are arranged opposite to each other. A slot 8 is provided on the sleeve shaft 3 on the inner side of the slide, and an inner and outer driving cylinders are provided at the inner end of the sleeve shaft 3 and the outer end of the slide 4 respectively, wherein the driving shaft of the inner driving cylinder 9 is provided with a pin 10, which passes through the slot 8 and is connected to the slide 5, and the driving shaft of the outer driving cylinder 11 passes into the slide 4 and is connected to the corresponding position of the sleeve shaft 3.

[0021] After the chloric acid disinfectant is prepared, it needs to be filled into bottles one by one using a filling machine. During the actual filling process, a conveyor platform is installed horizontally in front of the filling machine, and a bottle clamping mechanism is installed at the corresponding position of the filling machine via an optical axis. After the conveyor platform transports the corresponding number of empty bottles to the filling device of the filling machine, the bottle clamping mechanism first clamps the neck of each empty bottle. The filling head of the filling machine then moves downward until the filling head reaches the corresponding empty bottle one by one to fill the chloric acid disinfectant.

[0022] In this structure, each group of bottle clamping blocks has six blocks, so the number of filling heads in the filling machine is also six, and the filling heads are located directly above a pair of inner and outer bottle clamping blocks. When the empty bottles are transported to the filling position, the inner and outer driving cylinders respectively drive the slides, and the slides slide towards each other for a short distance. The inner and outer bottle clamping mounting plates respectively drive each group of bottle clamping blocks to move towards each other, and the corresponding inner and outer bottle clamping blocks move towards the corresponding empty bottles until their necks are clamped. Finally, the filling heads will move downward, and the filling heads will extend one by one to the corresponding empty bottles directly below them for filling and disinfection with chloric acid. This will prevent the bottles from shaking during the filling process, thereby improving the stability during filling.

[0023] In this structure, when the drive shaft of the inner drive cylinder drives the pin to move, the pin moves along the slot and drives the slide to slide on the sleeve. The filling machine and conveyor mentioned above are not the focus of this device and will not be described here.

[0024] In this structure, a leak-collecting trough 12 is located between the two sliding seats 4. When clamping an empty bottle, the two sliding seats slide toward each other, and the leak-collecting trough simultaneously slides away from the filling head in the filling machine. When filling is complete, the inner and outer drive cylinders drive the sliding seats in opposite directions and reset them. During this process, the leak-collecting trough moves toward the filling heads until it is directly below all the filling heads. Any excess liquid on the filling heads drips into the leak-collecting trough.

[0025] As a preferred structure, Figure 1 The front end of the bottle clamping block 7 is provided with a V-shaped groove 13, the bottom surface of the bottle clamping block is provided with a card slot 14, and the back of the bottle clamping block 7 is screwed with a resistance stud 141, and the resistance stud 141 resists the corresponding position of the bottle clamping mounting plate 6.

[0026] In this structure, the bottle clamp block is detachably mounted, making it easy to replace. During installation, the bottle clamp block is placed on the top surface of the bottle clamp mounting plate as required. At this time, the top surface of the bottle clamp mounting plate is located in the clamping groove. Finally, the interference stud is screwed into the back of the bottle clamp block until the end of the interference stud contacts the bottle clamp mounting plate.

[0027] Further as a preferred structure, Figure 3 A rack 15 is formed on the optical axis 1, and a driving gear 16 and a driven gear 23 are respectively rotatably provided in the lifting seat 2. The driving gear 16 and the driven gear 23 are meshed and installed. The end surface of the driven gear 23 is provided with a lifting gear 17, and the lifting gear 17 is meshed with the rack 15. An adjusting handwheel 18 is provided on the lifting seat 2, and the shaft of the adjusting handwheel 18 is connected to the end surface of the driving gear 16.

[0028] In this structure, by simultaneously adjusting the installation height of the two lifting seats, the positions of the two sets of bottle clamping blocks are changed sequentially to accommodate bottles of varying heights, thereby improving the adaptability of the bottle clamping mechanism. Specifically, turning the adjustment handwheel drives the driving gear, which, in conjunction with the driven gear, causes the lifting gear to rotate along the height direction of the rack. At this time, the lifting seats slide along the height direction of the same-side optical axis until the adjustment is in place.

[0029] In addition, if Figure 4-5 A fixed shaft 19 is fixed in the lifting seat 2, and a locking handle 20 is inserted into the lifting seat 2. The shaft of the locking handle 20 is a threaded rod, and the end of the threaded rod is rotatably connected to the fixed shaft 19. A locking shaft 21 is sleeved on the threaded rod, and the fixed shaft 19 and the locking shaft 21 form an arc surface 22 corresponding to the optical axis.

[0030] Once the lift is adjusted, turn the locking handle. The threaded rod on the locking handle rotates accordingly, causing the locking shaft to move toward the fixed shaft. The fixed and locking shafts then press against the optical axis. Once the locking handle is fully rotated, the lift locks onto the same side of the optical axis. This improves the stability of the lift, making the entire mechanism more stable and reliable.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
