Description

Technical Field

[0001] This utility model relates to the field of filling machine technology, and in particular to an antibacterial filling machine for beer PET kegs. Background Technology

[0002] PET drums are a common type of plastic container widely used in various scenarios, including liquid storage, transportation, and packaging. After beer production, it is usually necessary to use antimicrobial filling machines to fill the produced beer into PET drums for storage and convenient transportation.

[0003] For example, a beer PET keg antibacterial filling machine with announcement number "CN221854221U4" features a blind plug that connects to the filling head, creating a sealed space inside the filling head's inlet that isolates it from external air. The blind plug is used to connect with the filling head when filling is paused and is equipped with a disinfectant solution to effectively disinfect the filling head, preventing contamination at the filling port and ensuring the machine is always hygienic. However, this antibacterial beer PET keg filling machine lacks a limit stop for the PET keg during filling, making it susceptible to significant impact during the process, potentially causing it to tip over and spill beer, increasing operating costs. Furthermore, the filling head is typically mounted to the cylinder output end with multiple bolts. When the filling head is damaged and needs replacement, operators must rotate these bolts, taking considerable time and reducing work efficiency. Summary of the Invention

[0004] This invention aims to solve the problems existing in the prior art by providing an antibacterial filling machine for beer PET barrels. The PET barrels can be limited to reduce operating costs, and quick replacement can be achieved through the cooperation of a tension spring, a first gripper, and a second gripper.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: This antibacterial filling machine for beer PET barrels includes a base plate, a box body, and a curved plate. The upper two sides of the base plate are fixedly connected to the curved plate, and the upper protrusion of the base plate is fixedly connected to the box body. A limiting mechanism is provided inside the box body, and an installation mechanism is provided below the inner wall of the curved plate. An electric slide rail is installed inside the curved plate, and the electric slide rail is slidably connected to a sliding seat. A cylinder is fixedly connected to the bottom of the sliding seat, and a sterilization box is fixedly connected to the right side of the inner wall of the curved plate.

[0006] To further improve the system, a feed pipe is installed above the sterilization chamber, and a cover plate is installed above the feed pipe.

[0007] In a further improvement, the limiting mechanism includes a servo motor, with a gear fixedly connected to the end of the output shaft of the servo motor. The gear meshes with two racks, and the inner walls of the racks are slidably connected to fixed columns. Both ends of the fixed columns are fixedly connected to the housing. A movable block is fixedly connected to the front side of each rack, and the inner walls of the movable blocks are rotatably connected to a worm gear via bearings. The worm gear meshes with a worm wheel, and the upper part of the worm wheel drive shaft is rotatably connected to the movable block via bearings. The lower part of the worm wheel drive shaft is fixedly connected to a clamping block, and both sides of the clamping block are rotatably connected to the housing via bearings.

[0008] Further improvements include a fixed connection between the end of the servo motor and the housing.

[0009] In a further improvement, the installation mechanism includes an installation plate. The inner wall of the installation plate is movably connected to the first and second jaws via pins. First cylinders are fixedly connected to both sides of the first and second jaws. Multiple second cylinders are fixedly connected to the inner side of the installation plate. The second cylinders and the first cylinders are movably connected to both ends of a tension spring. The inner sides of the first and second jaws are pressed against the filling head.

[0010] Further improvements include a fixed connection between the top of the mounting plate and the cylinder output end, and a sealing gasket installed at the bottom of the mounting plate.

[0011] The beneficial effects of this utility model are as follows: Through the cooperation of the housing and the limiting mechanism, the servo motor output shaft rotates, driving the gears to rotate, which in turn causes two racks to slide along the outer wall of the fixed column. The movement of the racks drives the moving block to move, which in turn drives the clamping block to move. The rotation of the worm gear drives the worm wheel to rotate, which in turn drives the clamping block to rotate. This allows the PET container to be limited, preventing it from tipping over and spilling beer during filling, thus saving on labor costs.

[0012] With the cooperation of the mounting plate and the mounting mechanism, when the filling head contacts the first and second jaws, the first and second jaws slide outward and compress the tension spring. When the filling head enters the inner side of the first and second jaws, the tension spring returns to its original position, so that the inner side of the first and second jaws abuts against the outer wall of the filling head, thereby installing the filling head onto the mounting plate. This reduces the time required for installation and disassembly compared to operators turning multiple bolts, thus improving work efficiency. Attached Figure Description

[0028] Working principle:

[0029] When the anti-bacterial filling machine is used to fill beer into PRT barrels:

[0030] Preparation process:

[0031] The operator opens the cover plate on the feeding pipe 10, adds an appropriate amount of disinfectant into the sterilization box 11 (that is, the filling head can be completely soaked after entering the sterilization box 11), then covers the cover plate, and then connects the filling head 9 with the corresponding pipeline.

[0032] Filling process:

[0033] When filling and pausing in the middle, the operator starts the electric slide rail 5, which drives the sliding seat 6 to move, thereby driving the mounting plate 401 to move, and then the filling head 9 can be moved horizontally. When the filling head 9 moves above the feed pipe 10, the electric slide rail 5 is closed, the cover plate is opened, and then the cylinder 7 is started. The output end of the cylinder 7 extends to drive the filling head 9 into the sterilization box 11. When the sealing gasket 12 abuts against the feed pipe 10, the cylinder 7 is closed. The filling head 9 is sterilized by the disinfectant in the sterilization box 11 to prevent bacteria from entering the PET barrel during filling, causing the beer to deteriorate. After sterilization, the filling head 9 is restored to the initial position by the electric slide rail 5 and the cylinder 7.

[0034] The operator first adjusts the position of the rotating block 208 according to the shape of the PET barrel. The rotating rod worm 206 rotates to drive the worm gear 207 to rotate, thereby driving the clamp block 208 to rotate. When the clamp block 208 can be positioned to the PET barrel, stop rotating the worm 206. The worm 206 and the worm gear 207 have a self-locking function. Start the servo motor 201. The output shaft of the servo motor 201 rotates to drive the gear 202 to rotate, thereby driving the two racks 203 to slide along the outer wall of the fixed column 204. The movement of the rack 203 drives the moving block 205 to move, thereby driving the two clamp blocks 208 to move inward synchronously. When the inner sides of the clamp blocks 208 abut against the PET barrel, the servo motor 201 is closed. The servo motor 201 has a self-locking function. Then the operator starts the cylinder 7 to drive the mounting plate 401 to move downward, thereby driving the filling head 9 to move downward. When the filling head 9 enters the PET barrel, the cylinder 7 is closed. Then open the valve on the corresponding pipeline to make the beer enter the PET barrel through the filling head 9. When the PET barrel is filled, close the valve on the corresponding pipeline. Then the cylinder 7 drives the filling head 9 to reset. Then the operator reverses the output shaft of the servo motor 201 to drive the clamp block 208 to reset, and then take out the filled PET barrel to realize the positioning of the PET barrel, so that it does not tilt and spill beer during filling, thereby saving the working cost.

[0035] Filling head replacement process:

[0036] When the filling head 9 is damaged and needs to be replaced, for example, in the installation process, the new filling head 9 is moved upward, when the filling head 9 contacts the first claw 402 and the second claw 403, the first claw 402 and the second claw 403 slide outward and compress the tension spring 406, when the filling head 9 enters the inside of the first claw 402 and the second claw 403, the tension spring 406 resets, and the inside of the first claw 402 and the second claw 403 abuts tightly with the outer wall of the filling head 9, so as to install the filling head 9 on the mounting plate 401, when disassembly is needed, the operator pulls the filling head 9 downward with force, and the damaged filling head 9 can be pulled out from the inside of the first claw 402 and the second claw 403, compared with the time needed when the operator rotates a plurality of bolts for installation and disassembly, the time needed is shorter, so as to improve the work efficiency.
