Description

Technical Field

[0001] The present invention relates to the technical field of sterilization of beverage bottle filling production lines, and in particular to a sterilization system of a double grapefruit juice digital filling production line. Background Art

[0002] As the saying goes, "Food is the most important thing for people, and food safety is the first priority." Food hygiene and safety issues involve everyone's physical health and life safety. Improving the hygiene and safety awareness and capabilities of food manufacturers is crucial to building a healthy and safe food hygiene and safety environment.

[0003] On the double grapefruit juice filling production line, the inner wall of the beverage bottle needs to be sterilized. There are many ways to sterilize. Among them, deep ultraviolet light sterilization technology, which has the advantages of environmental protection and safety, high efficiency sterilization, broad spectrum, and no secondary pollution, is particularly prominent. It plays a decisive role in the surface sterilization and antibacterial of the beverage bottle production line.

[0004] Chinese patent CN217908401U discloses a deep ultraviolet sterilization device for a beverage bottle production line, which arranges deep ultraviolet LED lamp beads in a track-type groove, which can completely block the ultraviolet rays of the deep ultraviolet sterilization device, so that the ultraviolet rays only irradiate downward and not to the sides, realizing an ecological environment where humans and machines can coexist completely, and its own production capacity is not affected during operation and maintenance in the beverage production process; although the above scheme can directly maintain the deep ultraviolet LED lamp beads with problems, which has a certain protective effect on maintenance personnel, in some cases some deep ultraviolet LED lamp beads cannot be used, which reduces the irradiation time of the deep ultraviolet LED lamp beads and weakens the sterilization effect. At the same time, directly repairing the deep ultraviolet LED lamp beads on the sterilization production line cannot completely avoid the harm of ultraviolet rays to the human body.

[0060] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0061] Reference Figures 1 to 12As shown: A sterilization system of a double grapefruit juice digital filling production line, comprising a conveyor line 2 for conveying beverage bottles 1 and a sterilization device for sterilizing the beverage bottles 1, the sterilization device is composed of a plurality of sterilization units 3 arranged side by side, the sterilization unit 3 includes a mounting frame 31, the mounting frame 31 includes an upper support plate 311 and a lower support plate 312 parallel to each other, a support frame 3121 for placing the conveyor line 2 is provided in the middle of the upper surface of the lower support plate 312, a lifting mechanism 32 is provided on the side of the upper support plate 311 facing the lower support plate 312, the lifting mechanism 32 includes a lifting plate 321, a lifting plate 322, and a lifting plate 323. Two limiting grooves 3211 are provided on the upper surface of 21 along its length direction, and the two limiting grooves 3211 are symmetrically arranged about the middle surface of the lifting plate 321. Two U-shaped plates 322 are provided above the lifting plate 321. Under the opening of the U-shaped plate 322, and the two ends of the opening of the U-shaped plate 322 are respectively slidably set in the two limiting grooves 3211, and the main sterilization component 33 and the backup sterilization component 34 are arranged side by side below the lifting plate 321. The structures of the main sterilization component 33 and the backup sterilization component 34 are consistent, and the main sterilization component 33 and the backup sterilization component 34 are respectively connected to the two U-shaped plates 322.

[0062] The upper end of the lifting plate 321 is the first linear drive 323. During factory production, according to the sterilization requirements of the production line, several sterilization units 3 are arranged in an array side by side to form a sterilization device, so that a longer sterilization channel is formed. The main sterilization components 33 in several sterilization units 3 are on the same straight line, and the spare sterilization components 34 in several sterilization units 3 are on the same straight line. Then the conveyor line 2 of the beverage bottle 1 is placed in the sterilization channel and is below the straight line where the main sterilization components 33 are located. The conveyor line 2 conveys the beverage bottle 1 to the sterilization device, and the lifting mechanism 32 moves the main sterilization component 33 and The spare sterilization component 34 is raised and lowered to a height slightly higher than the bottle mouth, so that the beverage bottle 1 can obtain a better sterilization effect. When the main sterilization component 33 in the sterilization unit 3 is damaged and cannot work normally, the damaged main sterilization component 33 leaves the straight line where several main sterilization components 33 were originally located along the U-shaped plate 322. At the same time, the spare sterilization component 34 in the sterilization unit 3 moves to the straight line where several main sterilization components 33 were originally located, so that the sterilization units 3 missing on the sterilization production line can be replenished immediately, thereby ensuring that the production line can continue to operate after the main sterilization component 33 is damaged, and the sterilization effect of the sterilization device on the beverage bottle 1 remains unchanged.

[0063] Reference Figure 4 and Figure 5As shown: the surface of the lifting plate 321 is provided with a strip-shaped through groove 3212 along its length direction, the main sterilization component 33 includes an ultraviolet emitter 331, and the upper surface of the ultraviolet emitter 331 is provided with a connecting frame 332, the connecting frame 332 has two, and the two connecting frames 332 are symmetrically arranged about the middle surface of the ultraviolet emitter 331, the lower part of the connecting frame 332 is connected to the ultraviolet emitter 331, and the middle part of the upper surface of the connecting frame 332 is provided with a first connecting column 333, the lower end of the first connecting column 333 is connected to the middle part of the connecting frame 332, and a connecting column 333 is provided between the two first connecting columns 333. Rod 334, the axis of the connecting rod 334 is collinear with the axis of the lifting plate 321, the two ends of the connecting rod 334 are respectively connected to the upper ends of the two first connecting columns 333, and a double-headed connecting column 335 is provided in the middle of the connecting rod 334. The lower end of the double-headed connecting column 335 is connected to the middle of the connecting rod 334, and the upper end of the double-headed connecting column 335 is connected to the middle of the upper surface of the U-shaped plate 322. The main sterilization component 33 also includes an electric push rod 337, which is connected to one end of the lifting plate 321. The output shaft of the electric push rod 337 extends into the strip-shaped through groove 3212 and is connected to one end of the connecting rod 334.

[0064] The two connecting frames 332 symmetrically arranged on the upper end of the ultraviolet emitter 331 facilitate the ultraviolet emitter 331 to dissipate the high temperature generated during operation. The upper end of the double-headed connecting column 335 passes through the U-shaped plate 322, and the double-headed connecting column 335 and the U-shaped plate 322 are connected by nuts. The U-shaped plate 322 applies an upward pulling force to the double-headed connecting column 335, so that the connecting rod 334 is in the strip-shaped through groove 3212. When the ultraviolet emitter 331 in the main sterilization component 33 is damaged, the electric push rod 337 applies a pulling force toward itself to the connecting rod 334, so that The connecting rod 334 moves along the strip groove 3212, and at the same time, the electric push rod 337 in the spare sterilization component 34 applies a thrust to the connecting rod 334, pushing the ultraviolet emitter 331 in the spare sterilization component 34 to move to the top of the conveyor line 2. After the main sterilization component 33 that cannot work normally leaves its position, the staff loosens the nut at the connection between the double-headed connecting column 335 and the U-shaped plate 322, so that the main sterilization component 33 and the U-shaped plate 322 are quickly separated, so that the staff can remove the main sterilization component 33 that cannot work normally for maintenance.

[0065] Reference Figure 4 and Figure 6As shown: the lower end of the lifting plate 321 is also provided with a limiting structure 324 for limiting the moving direction of the ultraviolet emitter 331, the limiting structure 324 includes a limiting slide 3241, and the limiting slide 3241 has two, the two limiting slides 3241 are parallel to each other and the ends are flush, the plane where the two limiting slides 3241 are located is parallel to the plane where the lifting plate 321 is located, the limiting slide 3241 is slidably connected to the connecting frame 332, and a first mounting seat 3242 is provided at both ends of the limiting slide 3241, and the two ends of the first mounting seat 3242 are respectively connected to the same end of the two limiting slides 3241, and the upper surface of the first mounting seat 3242 is connected to the lower surface of the lifting plate 321.

[0066] When the push rod 337 pushes the connecting rod 334 to move along the bar groove 3212, the resistance at the lower end of the U-shaped plate 322 is small, causing the U-shaped plate 322 to deflect, and then the ultraviolet emitter 331 to deflect through the double-headed connecting column 335. Therefore, a limiting structure 324 is provided, and the two limiting slide bars 3241 are pressed against the upper surface of the connecting frame 332, so that the connecting frame 332 always remains parallel to the U-shaped plate 322. When the electric push rod 337 applies a thrust to the connecting rod 334, the connecting rod 334 moves close to the limiting slide bar 3241, and the U-shaped plate 322 only moves linearly along the limiting groove 3211, so that the emitting end of the ultraviolet emitter 331 is always vertically downward.

[0067] Reference Figure 6 and Figure 7 As shown: both ends of the upper surface of the connecting frame 332 are provided with limiting grooves 3321, and the two limiting grooves 3321 are symmetrically arranged about the middle surface of the connecting frame 332, and the upper half of the first connecting column 333 is provided with an adjustment groove 3331, and both ends of the connecting rod 334 pass through the adjustment grooves 3331 on the upper parts of the two first connecting columns 333, and the upper surface of the first connecting column 333 is provided with a threaded hole along its axial direction, and an adjusting bolt 336 is provided in the threaded hole, and the lower end of the adjusting bolt 336 is tightly pressed against the connecting rod 334.

[0068] When the locking cam 335 is in the unlocked position, the locking cam 336 will be in the unlocked position, and the winch 330 will be in the unlocked position, so that the winch 330 will not be locked.

[0069] Reference Figure 8 As shown: a first T-slot 3341 is provided on the surface of one end of the connecting rod 334 facing the electric push rod 337, and a third T-slot 3371 is provided on the surface of the output shaft of the electric push rod 337. The first T-slot 3341 is connected to the third T-slot 3371, and a first double-headed T-shaped connecting block 338 is provided in the first T-slot 3341 and the third T-slot 3371. The two ends of the first double-headed T-shaped connecting block 338 are respectively clamped with the first T-slot 3341 and the third T-slot 3371, and a first handle 3381 is provided in the middle of the first double-headed T-shaped connecting block 338.

[0070] The two ends of the first double-headed T-shaped connecting block 338 connect the output shaft of the electric push rod 337 and one end of the connecting rod 334. Even if the axis of the output shaft of the electric push rod 337 is offset from the axis of the connecting rod 334, the first double-headed T-shaped connecting block 338 can still connect the electric push rod 337 to the connecting rod 334. When the electric push rod 337 applies thrust to the connecting rod 334, the thrust is transmitted to the connecting rod 334 through the first double-headed T-shaped connecting block 338. After the electric push rod 337 moves the main sterilization component 33 out of its position, the maintenance personnel lifts the first handle 3381 and removes the first double-headed T-shaped connecting block 338 from between the electric push rod 337 and the connecting rod 334, thereby quickly separating the electric push rod 337 and the connecting rod 334.

[0071] Reference Figure 9 As shown: a second T-slot 3342 is provided on the surface of the other end of the connecting rod 334, and a second double-headed T-slot 3342 is provided between the second T-slot 3342 of the connecting rod 334 in the main sterilization component 33 and the second T-slot 3342 of the connecting rod 334 in the backup sterilization component 34, and both ends of the second double-headed T-slot 3342 are respectively engaged with the second T-slot 3342 at the opposite end of the two connecting rods 334, and a second handle 351 is provided in the middle of the second double-headed T-slot 35.

[0072] When the main sterilization component 33 cannot work normally, and the electric push rod 337 in the main sterilization component 33 cannot work normally, the electric push rod 337 in the backup sterilization component 34 works to push the backup sterilization component 34 to move, and transmits the thrust to the main sterilization component 33 through the second double-headed T-shaped connecting block 35, so that when only one electric push rod 337 can work normally, the main sterilization component 33 and the backup sterilization component 34 can still be switched.

[0073] Reference Figure 10 As shown: Several groups of auxiliary rolling structures 325 are arranged in an array at both ends of the opening of the U-shaped plate 322. The auxiliary rolling structure 325 includes a fixed shaft 3252. The middle part of the fixed shaft 3252 is connected to one end of the opening of the U-shaped plate 322. Rollers 3251 are provided at both ends of the fixed shaft 3252. The rollers 3251 are tangent to the bottom surface of the limiting groove 3211.

[0074] Since the U-shaped plate 322 is subjected to a large downward force, the friction between the U-shaped plate 322 and the lifting plate 321 is large. After long-term use, the U-shaped plate 322 will be worn, causing the height of the U-shaped plate 322 to change, and thus the lifting mechanism 32 cannot accurately control the height of the ultraviolet emitter 331. Therefore, auxiliary rolling structures 325 are provided at both ends of the opening of the U-shaped plate 322. Multiple groups of auxiliary rolling structures 325 can maintain the balance of the U-shaped plate 322. The auxiliary rolling structures 325 convert the sliding friction between the U-shaped plate 322 and the lifting plate 321 into rolling friction between the roller 3251 and the lifting plate 321, thereby avoiding the wear of the U-shaped plate 322, which causes the height of the ultraviolet emitter 331 to be unable to be accurately controlled.

[0075] Reference Figure 11 As shown: a guide column 313 is also provided between the upper support plate 311 and the lower support plate 312. There are four guide columns 313, which are respectively arranged at the four corners of the upper support plate 311. The upper end of the guide column 313 is connected to the upper support plate 311, and the lower end of the guide column 313 is connected to the lower support plate 312. Each guide column 313 is provided with a sliding sleeve 326, and the sliding sleeve 326 is connected to the lifting plate 321.

[0076] The main sterilization component 33 is located in the middle of the lifting plate 321, and the backup sterilization component 34 is located on one side of the lifting plate 321. When the main sterilization component 33 cannot work normally, the main sterilization component 33 moves to the other side of the lifting plate 321, and the backup sterilization component 34 moves to the middle of the lifting plate 321. At this time, the center of gravity of the lifting plate 321 changes, and the lifting plate 321 is very likely to be tilted. Therefore, a sliding sleeve 326 is provided, and the sliding sleeve 326 connects the lifting plate 321 with the guide column 313, so that the two ends of the lifting plate 321 remain horizontal, thereby avoiding the deflection of the lifting plate 321 caused by the movement of the main sterilization component 33 and the backup sterilization component 34.

[0077] Reference Figure 11 As shown: a hand push rod 314 is provided at one end of the lower support plate 312, the hand push rod 314 is set at an angle, the lower end of the hand push rod 314 is connected to one end of the lower support plate 312, and a universal wheel walking device 315 is provided at the lower end of the lower support plate 312.

[0078] When assembling several sterilization units 3 into a sterilization device, the staff can manually apply thrust to the sterilization unit 3 using the hand-held push rod 314 and simultaneously move the sterilization unit 3 using the universal wheel walking device 315, thereby facilitating the staff to transfer the sterilization unit 3 to the production line for assembly.
