Description

Technical Field

[0001] The invention relates to the field of PET wine barrel filling equipment. Background Art

[0002] In the field of barreled beer (20L barrels), the main trend in the market is to use metal steel barrels to hold beer. However, since metal steel barrels need to be recycled, recycling requires cleaning, and cleaning requires energy consumption such as cleaning agents, the cost of cleaning, including transportation, has remained high.

[0003] In order to solve the problem of recycling and cleaning, disposable PET plastic barrels containing beer spears have gradually become popular in recent years. Compared with the disadvantages of metal steel barrels that need to be recycled and cleaned, disposable PET plastic barrels are directly treated as waste after use and are not recycled, which greatly reduces the operating cost of the barrels and expands the sales radius of beer.

[0004] However, although disposable PET plastic barrels with beer spears have become popular, the barrel filling equipment is still very simple, with a production capacity of about 60 barrels per hour. Not only is the speed slow, but it also cannot achieve aseptic filling. Especially in the face of increasingly stringent food safety grade requirements, whether aseptic filling is possible will have a great impact on the hygiene, storage life and taste of barreled beer. On the other hand, if the entire workshop is sterilized, it will bring defects such as extremely high workshop construction costs, high daily use costs, and high maintenance costs.

[0005] In this regard, the Chinese invention patent application "Beer Aseptic Filling Machine" with application number "200810158205.7" discloses a technical solution to achieve aseptic filling by providing an aseptic positive pressure working environment. However, the filling operation workshop in this case has a large air contact area with the outside. Relying solely on membrane filter fans cannot provide a long-lasting and stable positive pressure environment, and it is also difficult to maintain the proposed aseptic positive pressure working environment.

[0006] Therefore, how to improve the filling equipment of PET barrels and achieve aseptic filling at a lower cost has become a technical problem that needs to be urgently solved by technical personnel in this field. Summary of the invention

[0072] In order to clearly illustrate the technical features of this patent, this patent is elaborated in detail below through a specific implementation method and in combination with its accompanying drawings.

[0073] The present invention Figure 1-35 As shown, the aseptic filling machine includes an inlet buffer bin 1, a cleaning and filling bin 2, an outlet buffer bin 3 and a fan filter unit 4. The inlet buffer bin 1 and the outlet buffer bin 3 are respectively fixedly connected to the inlet and the outlet of the cleaning and filling bin 2; the inlet buffer bin 1 is provided with a feed channel, and the outlet buffer bin 3 is provided with a discharge channel. In this case, a PET wine barrel is used as an example of a container. The container to be filled enters the cleaning and filling bin 2 through the feed channel, and is sent out through the discharge channel after filling.

[0074] The fan filter unit 4 is installed on the cleaning filling bin 2, and provides a sterile positive pressure environment to the cleaning filling bin 2 after the ambient air is filtered and pressurized by the fan filter unit 4;

[0075] The inner walls of the inlet buffer bin 1 and the outlet buffer bin 3 are fixedly connected with an isolation plate 5, the outer side of the isolation plate 5 is filled with the feed channel or the discharge channel, and a container channel for the container to enter and exit is opened in the isolation plate 5. As a result, the air in the aseptic filling machine and the ambient air in the workshop can only come into contact through the container channel. In this way, after the start of processing, the containers entering and exiting the cleaning filling bin 2 through the feed channel and the discharge channel will cooperate with the isolation plate 5, thereby greatly reducing the air contact area between the inside and outside of the aseptic filling machine, and then in the process of continuous entry and exit of the container, the fan filter unit 4 is used to provide a sterile positive pressure working environment for the cleaning filling bin 2 in a long-term and stable manner to ensure the aseptic filling of beer. This type of aseptic environment providing equipment has a simple structure, low manufacturing cost, low use cost, and can provide a sterile filling environment in a long-term and stable manner.

[0076] The container channel is consistent with the shape of the container, and when the container passes through the container channel, a gap is left between the container and the outer wall of the container. On the one hand, it can ensure that after the positive pressure sterile environment is established, the air can be exhausted to the outside through the above gap to avoid excessive pressure inside the sterile filling machine; on the other hand, it can also ensure that the air in the sterile filling machine and the ambient air in the workshop can only come into contact through the above gap, and the air contact area is extremely small.

[0077] Multiple isolation plates 5 are fixedly connected to the inner walls of the inlet buffer bin 1 and the outlet buffer bin 3, and the multiple isolation plates 5 are vertically arranged. Thus, the air contact area between the inside and outside of the aseptic filling machine can be better controlled in cooperation with the containers that are placed vertically and continuously move in the feed channel or the discharge channel, so as to avoid the positive pressure inside the aseptic filling machine being quickly released when the container and a certain isolation plate are opened at the wrong position.

[0078] About the wine spear pressing mechanism;

[0079] like Figure 5-7 As shown, the inlet buffer bin 1 also serves as a wine spear pressing mechanism, and the wine spear pressing mechanism includes a bin-in conveyor belt 16, an assembly mechanism, a front barrel cylinder 14, and a rear barrel cylinder 15;

[0080] The front barrel cylinder 14 and the rear barrel cylinder 15 are respectively arranged on the front and rear sides above the warehouse conveyor belt 16, and both are fixedly connected to the side wall of the import buffer warehouse 1. The cylinder rod of the front barrel cylinder 14 and the cylinder rod of the rear barrel cylinder 15 can extend into or out of the area above the warehouse conveyor belt 16, and a wine spear pressing station is formed between the front barrel cylinder 14 and the rear barrel cylinder 15.

[0081] The assembly mechanism is arranged above the wine spear pressing station, and the assembly mechanism includes an assembly cylinder 11 and a pressure plate 12. The assembly cylinder 11 is fixedly connected to the top of the inlet buffer bin 1, and the pressure plate 12 is fixedly connected to the bottom end of the assembly cylinder 11, and performs linear lifting motion under the drive of the assembly cylinder.

[0082] The operator can put a wine spear into the barrel mouth of the PET wine barrel before the PET wine barrel is sent into the import buffer warehouse 1. When in use, the front barrel blocking cylinder 14 can be opened first, so that the cylinder rod of the front barrel blocking cylinder enters the area above the warehouse feeding conveyor belt to block the PET wine barrel being transported. After the PET wine barrels corresponding to the number of assembling mechanisms enter the wine spear pressing station, the rear barrel blocking cylinder is opened, so that the cylinder rod of the rear barrel blocking cylinder enters the area above the warehouse feeding conveyor belt, thereby supporting the PET wine barrels on the front and rear sides of the wine spear pressing station, and making the PET wine barrels in the wine spear pressing station closely arranged, so as to realize the precise positioning of the PET wine barrels.

[0083] After that, the pressing plate 12 can be controlled to move downward by assembling the air cylinder 11, so that the pressing plate moves downward to contact the wine spear, and finally presses the wine spear into the barrel mouth of the PET wine barrel.

[0084] After the wine spear is pressed and installed, the cylinder rod of the front barrel cylinder can be controlled to withdraw from the area above the warehouse conveyor belt, so that the PET wine barrel with the wine spear installed can enter the next link under the transportation of the warehouse conveyor belt; after all the PET wine barrels with the wine spear installed leave the wine spear pressing station, the cylinder rod of the rear barrel cylinder is controlled to withdraw from the area above the warehouse conveyor belt to carry out the next wine spear pressing operation.

[0085] In this case, automated wine spear pressing equipment replaced traditional manual labor, which can accurately and efficiently complete the wine spear pressing operation, thereby effectively solving the problems of high labor intensity, low work efficiency and high pressing failure rate in the manual pressing process.

[0086] There are multiple assembly mechanisms, which are parallel to each other and arranged in sequence above the warehouse conveyor belt 16. Therefore, the wine spear pressing operation of a batch of PET wine barrels can be completed simultaneously through multiple assembly mechanisms to ensure the working efficiency of the wine spear pressing operation. Figure 7 As shown, the assembly mechanism has three PET wine barrels, and three PET wine barrels constitute a batch of PET wine barrels.

[0087] The wine spear pressing mechanism also includes a pair of side baffles 17, which are fixedly connected to the top of the warehouse conveyor belt 16, and the pair of side baffles 17 are located on both sides of the wine spear pressing station, and the container is supported from both sides of the container by the pair of side baffles 17. In this way, on the one hand, during the process of the warehouse conveyor belt moving the PET wine barrel, the container can be effectively supported by the pair of side baffles to maintain the stable transportation of the PET wine barrel; on the other hand, through the cooperation of the pair of side baffles 17 and the front barrel cylinder 14 and the rear barrel cylinder 15, a batch of PET wine barrels to be pressed can be closely arranged and stably and orderly placed in the wine spear pressing station.

[0088] There are two front barrel cylinders 14, which are arranged opposite to each other and both are arranged horizontally; there are two rear barrel cylinders 15, which are arranged opposite to each other and both are arranged horizontally. In this way, the two front barrel cylinders 14 and the two rear barrel cylinders 15 can effectively shorten the stroke required to extend, thereby speeding up the action efficiency, so as to speed up the working efficiency of the wine spear pressing operation to a certain extent.

[0089] The cylinder rods of the front barrel-blocking cylinder 14 and the rear barrel-blocking cylinder are fixedly connected to the barrel-blocking block 13, and the barrel-blocking block 13 is provided with an arc groove adapted to the outer wall of the container, and the arc groove is arranged toward the center of the wine spear pressing station. Thus, the barrel-blocking block can better block and support the PET wine barrel, and prevent the PET wine barrel from making unexpected movements during the wine spear pressing process, resulting in the failure of pressing.

[0090] The barrel stopper block 13 is made of PE to avoid scratching or squeezing the PET barrel.

[0091] A stroke sensor is installed on the assembly cylinder 11. The stroke sensor can be used to detect the actual stroke of the cylinder rod of the assembly cylinder and the pressure plate to determine whether the wine spear is pressed into place; in addition, if the stroke is too long, it can be determined that the press fitting fails and a waste product is produced.

[0092] About export buffer silo;

[0093] like Figure 8-9 As shown, the outlet buffer bin 3 is provided with an outlet conveyor belt 31, and both sides above the outlet conveyor belt 31 are respectively provided with outlet side baffles 32 fixedly connected to the outlet buffer bin 3. The outlet side baffles 32 support the PET wine barrel from both sides when the PET wine barrel is out of the bin.

[0094] About cleaning the filling silo;

[0095] People have found in actual use that most of the existing PET barrel filling equipment follows the steel barrel filling equipment and adopts the form of inverted filling. Inverted filling is simpler and more convenient for steel barrels, but it is not suitable for filling PET barrels. The main reason is that the structural strength of the PET barrel itself is much lower than that of the steel barrel. If inverted filling is adopted, as the beer is continuously poured in, the barrel body is very likely to become skewed, and even bend or break the barrel mouth. Therefore, it is necessary to design an additional barrel body support mechanism, which is not only complex in structure and high in design cost, but also a major problem in the coordinated control of various equipment. Therefore, how to simultaneously meet the requirements of inverted cleaning and upright filling has become a technical problem that needs to be solved urgently by technicians in this field.

[0096] like Figure 10-15 As shown, the cleaning and filling bin 2 includes a transfer bin 21, a cleaning bin 22 and a filling bin 23, one end of the in-bin conveyor belt 16 extends into the transfer bin 21, one end of the out-bin conveyor belt 31 extends into the filling bin 23, and the in-bin conveyor belt 16 and the out-bin conveyor belt 31 are parallel;

[0097] The transfer warehouse 21 has a transfer station, the cleaning warehouse 22 has a cleaning station, and the filling warehouse 23 has a filling station; one end of the in-warehouse conveyor belt 16 extends below the transfer station, and one end of the out-warehouse conveyor belt 31 extends below the filling station;

[0098] The container on the transfer station is clamped by the flipping mechanism and flipped to the cleaning station, or the container on the cleaning station is clamped by the flipping mechanism and flipped to the transfer station; the container is pushed from the transfer station to the filling station by the pushing mechanism. In this way, before filling the PET barrel, the PET barrel placed upright on the transfer station can be clamped by the flipping mechanism and flipped to the cleaning station, so that the PET barrel can be inverted in the cleaning station to complete the cleaning operation inside the PET barrel stably and efficiently; after the cleaning is completed, the PET barrel can be clamped by the flipping mechanism and flipped back to the transfer station; thereafter, the PET barrel can be pushed from the transfer station to the filling station by the pushing mechanism for upright filling. Finally, this case can meet the structural requirements of inverted cleaning and upright filling at the same time, and has the advantages of high processing efficiency, easy use and stable operation.

[0099] About cleaning the flipping mechanism and pushing mechanism in the filling bin;

[0100] like Figure 10-12As shown, the flip mechanism includes a flip motor 24, a flip shaft 25 and a clamping mechanism 26. The flip shaft 25 is rotatably connected to the frame, and the flip shaft 25 is arranged between the transfer station and the cleaning station in parallel with the length direction of the warehouse feeding conveyor belt 16. The flip motor 24 is fixedly connected to the frame, and the output shaft of the flip motor is connected to the flip shaft, and the flip shaft 25 is driven to reciprocate through the flip motor 24; one end of the clamping mechanism 26 is fixedly connected to the flip shaft 25; first, in the process of the PET barrel being sent to the transfer station, the flip shaft 25 can be rotated to "upward". The clamping mechanism is "lifted up", so that the PET wine barrel can smoothly enter the transfer station to avoid interference; after the PET wine barrel enters the transfer station, the clamping mechanism can be turned downward by rotating the turning shaft 25, and the barrel mouth of the PET wine barrel can be clamped by the clamping mechanism; thereafter, the turning motor is turned on again to control the clamping mechanism to turn 180°, so that the PET wine barrel placed upright on the transfer station can be clamped and turned over to the cleaning station, so that the PET wine barrel can be subsequently cleaned upside down in the cleaning station; similarly, after the cleaning is completed, the PET wine barrel can also be clamped by the turning mechanism and turned back to the transfer station.

[0101] like Figure 14-15 As shown, the pushing mechanism includes a pushing cylinder 27 and a pushing plate 28. The pushing cylinder 27 is fixedly connected to the frame, the pushing cylinder 27 is located at one side of the transfer station, and the cylinder rod of the pushing cylinder 27 is arranged toward the filling station, and the pushing plate 28 is fixedly connected to the cylinder rod of the pushing cylinder 27. When the cleaned PET barrel returns to the transfer station, the pushing cylinder 27 can be turned on to stably push the PET barrel to the filling station in a horizontal manner, so that the PET barrel can be filled upright in the filling station later.

[0102] A translation support plate fixedly connected to the frame is provided between the transfer station and the filling station. The translation support plate is fixedly connected to the frame and is located between the in-warehouse conveyor belt 16 and the out-warehouse conveyor belt 31 .

[0103] The push plate 28 has an arc-shaped groove on one side facing the filling station to match the container.

[0104] About cleaning the row positioning mechanism in the filling bin;

[0105] like Figure 14-15 As shown, the transfer bin 21 is further provided with a row positioning mechanism, which includes a transverse limiting rod 213 and a longitudinal limiting rod 214. The transverse limiting rod 213 is rotatably connected to the frame of the aseptic filling machine and is located on one side of the transfer station. The transverse limiting rod 213 blocks the container transported by the inlet conveyor belt 16, so that the container stays at the transfer station.

[0106] One end of the transverse limiting rod 213 is connected to a rotation driving mechanism, and the rotation driving mechanism drives the transverse limiting rod 213 to rotate back and forth;

[0107] One end of the longitudinal limiting rod 214 is fixedly connected to the transverse limiting rod 213 and is located between the transfer station and the filling station. The rotation of the transverse limiting rod 213 drives the longitudinal limiting rod 214 to swing up and down.

[0108] In addition, a filling positioning plate fixedly connected to the frame is provided on one side of the filling station away from the transfer station, and the filling positioning plate blocks the container pushed by the pushing mechanism, so that the container stays at the filling station.

[0109] Before the PET barrels are cleaned, the longitudinal limit rod 214 can be controlled to swing downward to a horizontal state, so that the longitudinal limit rod 214 is "blocked" between the transfer station and the filling station. In this way, the PET barrels transported by the warehouse conveyor belt 16 can stay at the same position each time, and the same batch of PET barrels can be kept closely arranged to facilitate the positioning of the PET barrels by the clamping mechanism. After the PET barrels are cleaned, the longitudinal limit rod 214 can be controlled to swing upward to a vertical state, thereby freeing up the action space between the transfer station and the filling station, so that the pushing mechanism can smoothly push the PET barrels from the transfer station to the filling station against the filling positioning plate, and because the pushing process is a translation push, the same batch of PET barrels will also be in the same position after each push, so as to facilitate the positioning of the PET barrels during filling.

[0110] Specifically, the transverse limiting rod 213 is simultaneously penetrated by two fixing seats 215 fixedly connected to the frame, so that the transverse limiting rod 213 can reciprocate around its own axis.

[0111] The rotary drive mechanism includes a limit cylinder 211, a connecting rod 212 and a second fixing seat 216. The second fixing seat 216 is fixedly connected to the frame, one end of the limit cylinder 211 is hinged on the second fixing seat 216, one end of the connecting rod 212 is hinged to the cylinder rod of the limit cylinder 211, and the other end is fixedly connected to the transverse limit rod 213. The transverse limit rod 213 is driven to reciprocate around its own axis by the extension or shortening of the limit cylinder 211. Further, the transverse limit rod 213 is perpendicular to the plane where the rotary drive mechanism is located. In this way, as the limit cylinder 211 is extended or shortened, it will directly drive the connecting rod 212 to swing back and forth, thereby driving the transverse limit rod 213 to reciprocate around its own axis, and driving the longitudinal limit rod 214 to swing up and down, so as to achieve a limit effect between the transfer station and the filling station.

[0112] About the clamping mechanism connected to the flipping mechanism in the cleaning filling bin;

[0113] Most of the clamping mechanisms in the prior art are aimed at small glass bottles or small cans, and cannot quickly, accurately and stably clamp PET barrels. Therefore, this case also proposes a clamping mechanism after the following optimized design.

[0114] like Fig.10 As shown, there are three clamping mechanisms, so that three batches of PET barrels can be clamped simultaneously.

[0115] like Figure 16-20 As shown, the clamping mechanism 26 includes a base 261, a clamping cylinder 262, a telescopic joint 263, a pair of driving connecting rods 264 and a pair of clamping claws 265. The root of the base 261 is fixedly connected to the flip shaft 25, the clamping cylinder 262 is fixedly connected to the base 261, and the telescopic joint 263 is fixedly connected to the cylinder rod of the clamping cylinder 262.

[0116] The roots of the pair of clamps 265 are hinged to the front of the base 261, and the pair of clamps 265 are symmetrically arranged along the center line of the clamping cylinder 262. One end of the driving connecting rod 264 is hinged to the clamps 265, and the other end of the pair of driving connecting rods 264 is hinged to the telescopic joint 263 at the same time. When in use, the pair of clamps 265 can be driven to open or close synchronously through the telescopic joint 263 and the pair of driving connecting rods 264 by the extension or shortening of the clamping cylinder 262. In this way, after the PET barrel is transported to the transfer station, the pair of clamps can be controlled to open and the entire clamping mechanism 26 can be turned downward. When the pair of clamps are on both sides of the position to be clamped, the clamping cylinder 262 is opened to make the pair of clamps close synchronously, so as to stably and efficiently clamp the barrel mouth of the PET barrel. It has the advantages of stable structure, high action efficiency and good clamping effect.

[0117] The expansion joint 263 is sleeved with the cylinder rod of the clamping cylinder 262, and the expansion joint 263 and the cylinder rod of the clamping cylinder 262 are connected by threads, so that the relative position of the expansion joint 263 and the cylinder rod of the clamping cylinder 262 is adjustable.

[0118] In actual use, people also found that because the clamp is in the form of a sheet, it needs to maintain good shape stability during the clamping process and maintain good connection stability with the base. The shape stability of the clamp itself can be solved by selecting a higher strength metal material, and the connection stability between it and the base needs to be solved through the following optimization measures.

[0119] A support block 266 is also provided at the front of the base 261, and the bottom surface of the support block 266 is completely attached to the base 261. A pair of clamping jaws 265 are pressed on the top surface of the support block 266 through bolt 1, and a bushing is sleeved on the outer wall of bolt 1. Thus, the clamping jaw can rotate freely around bolt 1, and can also keep in contact with the top surface of the support block as much as possible under the action of bolt 1, thereby significantly improving the connection stability between the clamping jaw and the base by increasing the contact area.

[0120] The clamping jaw 265 is L-shaped, and is connected to the driving connecting rod 264 through bolt 2, and a bushing is also sleeved on the outer wall of bolt 2, so as to realize the hinged structure of the clamping jaw and the driving connecting rod, and the distance between bolt 2 and bolt 1 is smaller than the length of the driving connecting rod 264. Therefore, by driving the clamping jaw through a longer driving connecting rod, the actual working stroke of the clamping cylinder can be effectively reduced, so that the clamping jaw has the advantages of high action efficiency and high action speed.

[0121] The clamping jaw 265 is provided with an arc-shaped clamping groove on one side facing the center line of the clamping cylinder 262 , and the front portion of the clamping groove is in an arc shape that matches the outer diameter of the container mouth.

[0122] The container is a PET wine barrel, and a convex ring for connecting a wine spear is provided on the outer wall of the barrel mouth of the PET wine barrel, and the thickness of the clamping claw 265 is smaller than the distance between the convex ring and the barrel body of the PET wine barrel, so as to ensure that the clamping claw can extend between the convex ring and the barrel body to stably clamp the barrel mouth of the PET wine barrel.

[0123] A stroke sensor is installed on the clamping cylinder 262. Thus, the actual stroke of the cylinder rod of the clamping cylinder can be detected by means of the stroke sensor to determine whether the clamping of the PET barrel has been in place.

[0124] About the cleaning chamber in the cleaning filling chamber;

[0125] At present, the inner wall of the PET barrel, which is in direct contact with the beer, must be cleaned before filling the beer into the PET barrel to better achieve the purpose of aseptic filling. However, most traditional cleaning equipment can only clean steel barrels. Since the structure of the beer spear of the PET barrel is different from that of the steel barrel, the traditional cleaning equipment is not well suitable for the cleaning of the PET barrel. Specifically, the beer spear of the PET barrel is mostly as shown in a Chinese utility model patent entitled "A kind of beer spear and a barrel with the beer spear" and application number "201921996860.X" announced on September 8, 2020. This kind of beer spear is also called a beer spear. When the wine outlet sealing ring is pressed in the direction of the inside of the PET barrel, the beer spear is in an open state. At this time, there are two channels inside and outside the wine outlet pipe respectively. During the wine outlet process, gas can be filled into the PET barrel through the external channel for pressurization, so that the beer flows out from the internal channel through the wine outlet pipe. In this way, if the inside of the PET barrel needs to be cleaned, the cleaning liquid must be able to flow from the internal channel of the wine spear and the wine outlet pipe to the bottom of the PET barrel, and after cleaning, it must be able to flow out through the external channel of the wine spear. These technical contents do not need to be considered during the cleaning process of steel barrels.

[0126] Therefore, how to make the cleaning liquid smoothly enter the interior of the PET wine barrel and be discharged smoothly after cleaning has become a technical problem that needs to be urgently solved by technical personnel in this field.

[0127] like Fig.13 As shown, the cleaning chamber 22 is provided with a cleaning valve 221 located below the cleaning station and a container pressing plate 222 located above the cleaning station. The container pressing plate 222 is connected to the top of the cleaning chamber 22 through a downward pressure cylinder 223, and the container pressing plate 222 is controlled by the downward pressure cylinder 223 to perform reciprocating lifting motion;

[0128] The cleaning valve 221 has a liquid inlet channel and a liquid outlet channel;

[0129] The wine outlet sealing ring in the wine spear is forced to open upwards through the cleaning valve 221, so that the liquid inlet channel is connected to the internal channel of the wine spear, and the liquid outlet channel is connected to the external channel of the wine spear.

[0130] The liquid inlet channel is connected to the cleaning liquid through the liquid inlet interface, and the liquid outlet channel is connected to the wastewater tank through the liquid outlet interface.

[0131] like Fig.10 As shown, there are three cleaning valves and three container pressure plates respectively, so that three batches of PET wine barrels can be cleaned simultaneously.

[0132] In this way, after the turning mechanism turns the PET wine barrel over and places it in an inverted form at the cleaning station, the wine spear will first naturally dock with the cleaning valve, and then the downward pressure cylinder 223 is opened, so that the container pressing plate 222 moves downward to press the inverted PET wine barrel, thereby preventing the PET wine barrel from unexpectedly moving during the cleaning process; thereafter, the cleaning valve is opened to force the wine outlet sealing ring in the wine spear to open upward, so that the liquid inlet channel is connected to the internal channel of the wine spear, and the cleaning liquid is filled into the PET wine barrel through the internal channel of the wine spear and the wine outlet pipe. At the same time, since the liquid outlet channel is connected to the external channel of the wine spear, the cleaning liquid in the PET wine barrel can also be smoothly discharged outward through the external channel of the wine spear, thereby achieving efficient cleaning of the inverted PET wine barrel. Fig.34 It has the advantages of good use effect, stable operation and high cleaning efficiency.

[0133] like Figure 21-23 As shown, the cleaning valve 221 includes a cleaning valve body 2211, a cleaning valve base 2212, a cleaning valve core 2213 and a cleaning cylinder 2214. The cleaning cylinder 2214 and the cleaning valve body 2211 are fixedly connected to the frame, the liquid outlet channel is opened in the cleaning valve body 2211, the cleaning valve core 2213 is penetrated in the liquid outlet channel, and the bottom end of the cleaning valve core 2213 is fixedly connected to the cylinder rod of the cleaning cylinder 2214, and the cleaning valve core 2213 is driven by the cleaning cylinder 2214 to perform reciprocating lifting motion relative to the cleaning valve body 2211; the liquid inlet channel is opened in the cleaning valve core 2213;

[0134] The top of the cleaning valve core 2213 is provided with a wine spear top ring that is adapted to the wine outlet sealing ring in the wine spear, the top of the cleaning valve body 2211 is provided with a wine spear accommodating groove that is adapted to the outer wall of the wine spear, the wine spear accommodating groove is connected to the liquid outlet channel, and the wine spear top ring is located at the top opening of the liquid inlet channel, that is, the tops of the cleaning valve body 2211 and the cleaning valve core 2213 are both open, and the cleaning valve base 2212 is fixedly connected to the bottom opening of the liquid outlet channel, the cleaning valve base 2212 is sleeved on the cleaning valve core 2213, and a dynamic seal is maintained between the two. In this way, after the wine spear on the PET wine barrel is docked with the cleaning valve and the PET wine barrel is stably pressed by the container pressure plate 222, the cleaning cylinder 2214 can be opened to drive the cleaning valve core 2213 to move upward, thereby pushing up the wine outlet sealing ring, so that the liquid inlet channel inside the cleaning valve core 2213 is connected with the internal channel of the wine spear, and the liquid outlet channel outside the cleaning valve core 2213 is connected with the external channel of the wine spear.

[0135] The cleaning valve base 2212 maintains dynamic sealing with the cleaning valve core 2213 through the bellows sealing structure 1. Thus, the dynamic sealing effect is better achieved with the bellows sealing structure.

[0136] Specifically, the bellows sealing structure 1 includes a bellows 1 2215 and a positioning sleeve 1 2216, wherein the positioning sleeve 1 2216 is tightly arranged between the cleaning valve base 2212 and the cleaning valve core 2213, the bellows 1 2215 is arranged at the bottom of the liquid outlet channel and sleeved with the cleaning valve core 2213, the top end of the bellows 1 2215 is fixedly connected to the outer wall of the cleaning valve core 2213, and the bottom end of the bellows 1 2215 is fixedly connected to the positioning sleeve 1 2216. In this way, the bellows 1 2215 will shrink or expand with the linear reciprocating motion of the cleaning valve core 2213 during use, thereby maintaining an efficient sealing state at all times, and has a good sealing effect and a long service life.

[0137] The cleaning valve core 2213 is coaxial with the liquid outlet channel, thereby making the overall structure more delicate and more stable.

[0138] About cleaning the filling silo in the filling silo;

[0139] Most of the existing PET barrel filling equipment uses the filling equipment for steel barrels and adopts the inverted filling method. Inverted filling is simpler and more convenient for steel barrels, but it is not suitable for filling PET barrels. The main reason is that the structural strength of the PET barrel itself is much lower than that of the steel barrel. If inverted filling is adopted, as the beer is continuously poured in, the barrel body is very likely to become skewed, and even bend or break the barrel mouth. Therefore, it is necessary to design an additional barrel body support mechanism, which is not only complex in structure and high in design cost, but also the coordinated control of various equipment is also a major problem.

[0140] In addition, during inverted filling, a downward pressure device needs to be installed at the bottom of the PET barrel, otherwise the wine spear cannot be pushed, and the wine outlet sealing ring in the wine spear cannot move relative to the PET barrel, which undoubtedly brings great additional costs to the inverted filling equipment.

[0141] like Figure 24-33As shown, the filling bin 23 is provided with a filling valve 231 connected above the filling station, and the filling valve 231 includes an upper cylinder 2311, an outer connecting rod 2312, a filling valve body 2313, an inner connecting rod 2314, a lower cylinder 2315, a filling valve core 2316 and a filling valve base 2317. The upper cylinder 2311 is fixedly connected above the filling station, and the filling valve body 2313 is arranged below the upper cylinder 2311 and is connected to the cylinder rod of the upper cylinder 2311 through the outer connecting rod 2312. The filling valve body 2313 is fixedly connected to the upper cylinder 2311, so that the filling valve body 2313 can make reciprocating lifting motion under the drive of the upper cylinder 2311; the lower cylinder 2315 is fixedly connected to the upper part of the filling valve body 2313 through the inner connecting rod 2314, the filling valve core 2316 is inserted into the filling valve body 2313, and the top of the filling valve core 2316 is fixedly connected to the cylinder rod of the lower cylinder 2315, so that the filling valve core 2316 can make reciprocating lifting motion relative to the filling valve body 2313 under the drive of the lower cylinder 2315;

[0142] The filling valve body 2313 is provided with an exhaust channel, the filling valve core 2316 is provided with a wine injection channel, the filling valve core 2316 is inserted into the exhaust channel, the filling valve base 2317 is fixedly connected to the top of the exhaust channel, the filling valve base 2317 is sleeved on the filling valve core 2316, and the filling valve base 2317 and the filling valve core 2316 maintain a dynamic seal.

[0143] like Fig.10 As shown, there are three filling valves, so that three batches of PET wine barrels can be filled simultaneously.

[0144] The bottom of the filling valve body 2313 has a wine spear pressure groove adapted to the outer wall of the wine spear, the bottom of the filling valve core 2316 has a wine spear pressure ring adapted to the wine outlet sealing ring in the wine spear, the wine spear pressure groove is connected to the exhaust channel, and the wine spear pressure ring is located at the bottom of the wine injection channel. When the filling valve body 2313 moves downward under the action of the upper cylinder 2311 to dock with the wine spear, the wine spear pressure groove will cover the wine spear, and when the filling valve core 2316 moves downward under the action of the lower cylinder 2315, the wine spear sealing ring can be pushed downward by the wine spear pressure ring, so that the wine injection channel can be connected to the internal channel of the wine spear, and the exhaust channel can be connected to the external channel of the wine spear.

[0145] The beer injection channel is connected to the beer to be filled through the beer injection interface, and the exhaust channel is connected to the exhaust gas collection device through the exhaust interface.

[0146] When in use, it is necessary to wait for the cleaned PET wine barrel to enter the filling station. After that, the upper cylinder 2311 can be used to drive the filling valve body 2313, the inner connecting rod 2314, the lower cylinder 2315, and the filling valve core 2316 to move downward synchronously, so that the wine spear pressure groove can be stably covered on the wine spear, completing the docking of the filling valve body 2313 and the wine spear. After that, the lower cylinder 2315 can be used to drive the filling valve core 2316 to move downward relative to the filling valve body 2313, so that the wine spear sealing ring can be pushed downward by the wine spear pressure ring, so that the wine injection channel on the inner side of the filling valve core can be connected to the internal channel of the wine spear, and the exhaust channel on the outer side of the filling valve core can be connected to the external channel of the wine spear. In this way, it can be done as follows. Fig.35 As shown, the PET barrels can be filled efficiently, stably and aseptically. During the filling process, since the PET barrels are always in an upright state, there will be no defects of inverted filling. The filling effect is good and no other supporting or clamping equipment is required.

[0147] The filling valve further comprises a guide mechanism, which comprises a mounting seat 2321, a guide rod 2322, an upper fixing plate 2323 and a lower fixing plate 2324. The mounting seat 2321 is fixedly connected to the frame and sleeved with the filling valve body 2313; thereby, the linear reciprocating motion made by the filling valve body driven by the upper cylinder is more stable and has better tracking performance;

[0148] The upper fixing plate 2323 is fixedly connected to the cylinder body of the upper cylinder 2311, and the upper fixing plate 2323 and the mounting seat 2321 are fixedly connected through the guide rod 2322. The lower fixing plate 2324 is fixedly connected to the lower cylinder 2315. The lower fixing plate 2324 is also sleeved with the guide rod 2322 and is slidably connected to the guide rod. The upper cylinder 2311, the lower cylinder 2315, the guide rod 2322, the filling valve core 2316, and the filling valve body 2313 are all vertically arranged. In this way, the guiding mechanism can be used to guide the filling valve body 2313, the inner connecting rod 2314, the lower cylinder 2315, and the filling valve core 2316 in a synchronous upward and downward movement, so that the operation of the equipment has better stability and reliability, thereby ensuring that the wine spear pressure groove is stably and accurately covered on the wine spear.

[0149] The filling valve base 2317 maintains dynamic sealing with the filling valve core 2316 through the bellows sealing structure 2, thereby achieving a better dynamic sealing effect with the help of the bellows sealing structure.

[0150] Specifically, the second bellows sealing structure includes a second bellows 2331 and a second positioning sleeve 2332. The second positioning sleeve 2332 is tightly arranged between the filling valve base 2317 and the filling valve core 2316. The second bellows 2331 is arranged at the top of the exhaust channel and sleeves the filling valve core 2316. The bottom end of the second bellows 2331 is fixedly connected to the outer wall of the filling valve core 2316, and the top end of the second bellows 2332 is fixedly connected to the second positioning sleeve 2332. In this way, the second bellows 2331 will shrink or expand with the linear reciprocating motion of the filling valve core 2316 during use, so as to always maintain an efficient sealing state, and its sealing effect is good and the service life is long.

[0151] The filling valve core 2316 is coaxial with the exhaust channel, so that the overall structure is more delicate and more stable.

[0152] There are many specific implementation ways of the present invention. The above is only the preferred implementation mode of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements can be made without departing from the principle of the present invention. These improvements should also be regarded as the protection scope of the present invention.
