Description

Technical Field

[0001] This application relates to the field of bottle cap sterilization technology, and in particular to a bottle cap sterilization device. Background Technology

[0002] Aseptic cold filling technology for PET bottled beverages refers to filling aseptic materials into aseptic packaging materials in an aseptic environment. The packaging materials refer to PET bottles and bottle caps. Therefore, the degree of sterilization of bottle caps has a great impact on high-requirement production lines such as aseptic cold filling and ultra-clean filling, and the sterilization method of bottle caps determines their sterilization effect.

[0003] Common bottle cap sterilization devices mainly include a closed conveying orifice and a sterilization device connected to the conveying orifice. The conveying orifice contains, in sequence, a sterile air blowing and turning device, a sterile water spraying device, and a sterile air drying device. A bottle cap conveying device also passes through the conveying orifice. A cap feeder connected to the sterilization device is located above it. The sterilization device includes an immersion tank containing a sterilization track consisting of at least two involute tracks. Above the immersion tank is at least one sterilization liquid spraying assembly. Each sterilization liquid spraying assembly includes: a spray pipe spanning the sterilization track; each spray pipe has at least two spray branches corresponding to one involute track; and each spray branch has a spray hole pointing towards that involute track.

[0004] After the bottle caps are neatly arranged in the cap feeder, they are guided by a cap dropping track so that the cap openings face upwards and enter a disc-shaped involute track with a certain level of disinfectant liquid. Suspended in the involute track, the bottle caps are immersed in disinfectant and move along the involute track by the impact force provided by the disinfectant spraying system and the resulting swirling force of the disinfectant in the chamber. After leaving the involute track, the bottle caps are rotated 180 degrees by a specially designed reversing guide under the action of sterile gas, so that the cap openings face downwards to pour out the disinfectant into the collection tank on the frame. The bottle caps are then guided by a track into the sterile water rinsing area. After being rinsed by the sterile water spray device, they enter the sterile air drying area, where the sterile air drying device dries the bottle caps. Finally, they are sent to the capping machine.

[0005] The effectiveness of bottle cap disinfection is related to the effective immersion time of the bottle cap in the disinfectant solution. Since the length of the bottle cap track inside the sterilization tank is a known value, existing technologies mainly control the conveying speed of the bottle caps in the bottle cap track to keep the conveying speed constant, thereby controlling the immersion time of the bottle caps in the disinfectant solution.

[0006] However, existing bottle cap sterilization devices cannot monitor the soaking time of bottle caps in disinfectant. If the disinfectant spraying system malfunctions and causes the bottle cap delivery speed to be too fast or too slow, operators cannot promptly inspect and maintain the bottle cap sterilization device, making it difficult to guarantee the sterilization effect and efficiency of the bottle caps. There is room for improvement. Utility Model Content

[0007] In order to monitor the conveying speed of bottle caps and achieve the technical effect of detecting the soaking and sterilization time of bottle caps, this application provides a bottle cap sterilization device.

[0008] The bottle cap sterilization device provided in this application adopts the following technical solution:

[0009] A bottle cap sterilization device mainly includes a mounting bracket, which is fixedly installed on a liquid collection tank; and:

[0010] The ranging unit is detachably mounted on the mounting bracket and placed above the liquid collection tank. It is used to detect the distance between itself and the shielding surface below and output a sensed distance signal.

[0011] The comparator chip is connected to the signal output terminal of the ranging unit and is used to output a high-level signal when the sensing distance is less than a set value.

[0012] A microcontroller is connected to the signal output terminal of the comparator chip to calculate the frequency of high-level signals and output an alarm control signal when the frequency of high-level signals exceeds a set range.

[0013] A buzzer is fixedly mounted on the mounting bracket and connected to the signal output terminal of the microcontroller. It is used to receive the alarm control signal and emit an alarm sound.

[0014] By adopting the above technical solution, during the actual production and processing, the bottle caps conveyed through the collection tank can be detected by the ranging unit. When the bottle cap passes under the mounting bracket, if the sensing distance measured by the ranging unit is less than the set value, the comparator chip outputs a high-level signal. The microcontroller calculates the frequency of the high-level signal to provide feedback on the conveying efficiency of the bottle caps: the faster the bottle cap passes under the ranging unit, the higher the conveying speed of the bottle caps, and the shorter the time the bottle caps spend in the soaking tank for disinfection. When the frequency of the high-level signal exceeds the set range, the microcontroller controls the buzzer to sound an alarm. This can automatically prompt on-site operators to promptly inspect and maintain the bottle cap sterilization device when the conveying speed of the bottle cap sterilization device is abnormal. This can effectively prevent situations where the bottle caps are conveyed too quickly, resulting in insufficient soaking time, or that the bottle caps are conveyed too slowly, resulting in low sterilization efficiency.

[0015] Preferably, a mounting top plate is fixedly mounted on the mounting bracket, and the mounting top plate is erected above the liquid collection tank;

[0016] The ranging unit includes a mounting box, which is detachably mounted on the mounting top plate. A connecting plate is detachably mounted on the top of the mounting box, and an ultrasonic ranging sensor is fixedly mounted on the bottom of the connecting plate. The signal output terminal of the ultrasonic ranging sensor is connected to the signal output terminal of the comparator chip.

[0017] The bottom of the mounting box has a first through hole, and the top mounting plate has a second through hole. The first through hole and the second through hole are coaxial, and the sensing end of the ultrasonic ranging sensor is mounted above the first through hole and the second through hole.

[0018] By adopting the above technical solution, during the actual testing process, the ultrasonic waves emitted by the sensing end of the ultrasonic ranging sensor can be emitted through the first through hole and the second through hole, and the bottle cap passing under the mounting bracket in the liquid collection tank can be detected.

[0019] Preferably, a first sleeve is fixedly installed inside the mounting box, and a third through hole coaxial with the first through hole is opened through the first sleeve. A receiving cavity for placing desiccant is formed between the outer wall of the first sleeve and the inner wall of the mounting box.

[0020] By adopting the above technical solution, in actual use, the operator can place a desiccant in the containment cavity. The desiccant in the containment cavity can absorb the moisture in the environment, providing a dry detection environment for the ultrasonic ranging sensor.

[0021] Preferably, a second sleeve is fixedly installed on the mounting top plate, the outer wall of the second sleeve is fixed to the inner wall of the second through hole by welding, and the first sleeve is coaxially sleeved on the outer side of the second sleeve;

[0022] The second sleeve has a fourth through hole, which is coaxial with the second through hole.

[0023] By adopting the above technical solution, the second sleeve allows operators to pre-position the installation box using the second sleeve and the first sleeve when installing the installation box.

[0024] Preferably, the bottom end of the second sleeve is threaded with a cap, which covers the bottom end face of the second sleeve.

[0025] By adopting the above technical solution, the cover can be removed when the ultrasonic ranging sensor is needed; after use, the cover can be installed at the bottom of the second sleeve to reduce the possibility of moisture entering the mounting box through the second sleeve.

[0026] Preferably, fixing plates are fixedly installed on the two side walls of the mounting box, and the two fixing plates are respectively installed on the mounting top plate by bolts.

[0027] By adopting the above technical solution, the two fixing plates make it easy for operators to fix the mounting box to the mounting top plate of the mounting bracket with bolts.

[0028] In summary, the bottle cap sterilization device of this application has at least one of the following beneficial technical effects:

[0029] 1. During actual production and processing, the bottle caps conveyed through the collection tank can be detected by the ranging unit. When the bottle cap passes under the mounting bracket, if the sensing distance measured by the ranging unit is less than the set value, the comparator chip outputs a high-level signal. The microcontroller calculates the frequency of the high-level signal to provide feedback on the conveying efficiency of the bottle caps: the faster the bottle cap passes under the ranging unit, the higher the conveying speed of the bottle caps, and the shorter the time the bottle caps spend in the soaking tank for disinfection. When the frequency of the high-level signal exceeds the set range, the microcontroller controls the buzzer to sound an alarm. This can automatically prompt the on-site operators to inspect and maintain the bottle cap sterilization device in a timely manner when the conveying speed of the bottle caps is abnormal. This can effectively prevent the bottle caps from being conveyed too fast, resulting in insufficient soaking time, or from being conveyed too slowly, resulting in low sterilization efficiency.

[0030] 2. The desiccant inside the housing absorbs moisture from the environment, providing a dry detection environment for the ultrasonic ranging sensor.

[0031] 3. With the cover installed, the operator can remove the cover when the ultrasonic ranging sensor is needed; after use, the operator can install the cover at the bottom of the second sleeve to reduce the possibility of moisture entering the mounting box through the second sleeve.

[0038] During actual production and processing, the bottle caps 6 conveyed through the collection tank 2 can be detected by the ranging unit 3. When the bottle cap 6 passes under the mounting bracket 1, if the sensing distance measured by the ranging unit 3 is less than the set value, the comparator chip outputs a high-level signal. The microcontroller calculates the frequency of the high-level signal and provides feedback on the conveying efficiency of the bottle caps: the faster the bottle cap passes under the ranging unit 3, the higher the conveying speed of the bottle caps, and the shorter the time the bottle caps spend in the soaking tank 5 for disinfection. When the frequency of the high-level signal exceeds the set range, the microcontroller controls the buzzer 4 to sound an alarm. This can automatically prompt the on-site operators to inspect and maintain the bottle cap sterilization device in a timely manner when the conveying speed of the bottle caps is abnormal. This can effectively prevent the bottle caps from being conveyed too fast, resulting in insufficient soaking time, or from being conveyed too slowly, resulting in low sterilization efficiency.

[0040] The bottom of the mounting box 31 has a first through hole 34, and the top mounting plate 11 has a second through hole 12. The first through hole 34 and the second through hole 12 are coaxial. The sensing end of the ultrasonic ranging sensor 33 is mounted above the first through hole 34 and the second through hole 12.

[0042] Reference Figure 2 A first sleeve 35 is fixedly installed inside the mounting box 31. A third through hole 36 coaxial with the first through hole 34 is opened through the first sleeve 35. A receiving cavity 37 for placing desiccant is formed between the outer wall of the first sleeve 35 and the inner wall of the mounting box 31.

[0043] In actual use, the operator can place a desiccant in the receiving cavity 37. The desiccant in the receiving cavity 37 can absorb the moisture in the environment, providing a dry detection environment for the ultrasonic ranging sensor 33.

[0044] Reference Figure 2 A second sleeve 13 is fixedly installed on the top plate 11. The outer wall of the second sleeve 13 is fixed to the inner wall of the second through hole 12 by welding. The first sleeve 35 is coaxially sleeved on the outside of the second sleeve 13. A fourth through hole 14 is opened through the second sleeve 13. The fourth through hole 14 is coaxially arranged with the second through hole 12.

[0045] The second sleeve 13 allows operators to pre-position the mounting box 31 using the second sleeve 13 and the first sleeve 35 when installing the mounting box 31.

[0046] Reference Figure 2 The bottom end of the second sleeve 13 is threaded with a cover 15, which covers the bottom end face of the second sleeve 13. With the cover 15, when the ultrasonic ranging sensor 33 needs to be used, the operator can remove the cover 15; after use, the operator can install the cover 15 at the bottom of the second sleeve 13 to reduce the occurrence of moisture entering the mounting box 31 through the second sleeve 13.

[0047] Reference Figure 2 Fixing plates 38 are fixedly installed on the two side walls of the mounting box 31, and the two fixing plates 38 are respectively installed on the mounting top plate 11 by bolts. Both the mounting top plate 11 and the two fixing plates 38 have through holes for the bolt shanks to pass through. The fixing plates 38 are tightly fitted against the mounting top plate 11 between the bolt bolt and the nut. The two fixing plates 38 allow operators to easily fix the mounting box 31 to the mounting top plate 11 of the mounting bracket 1 using bolts.

[0048] The implementation principle of the bottle cap sterilization device in this application embodiment is as follows: During the actual production process, the bottle caps conveyed through the collection tank 2 can be detected by the ranging unit 3. When the bottle cap passes under the mounting bracket 1, if the sensing distance measured by the ranging unit 3 is less than the set value, the comparator chip outputs a high-level signal. The microcontroller calculates the frequency of the high-level signal and can provide feedback on the conveying efficiency of the bottle caps: the faster the frequency of the bottle caps passing under the ranging unit 3, the higher the conveying speed of the bottle caps, and the shorter the time the bottle caps spend in the soaking tank 5 for disinfection. When the frequency of the high-level signal exceeds the set range, the microcontroller controls the buzzer 4 to sound an alarm. This can automatically prompt the on-site operators to inspect and maintain the bottle cap sterilization device in a timely manner when the conveying speed of the bottle caps is abnormal. This can effectively prevent the bottle caps from being conveyed too fast, resulting in insufficient soaking time, or from being conveyed too slowly, resulting in low sterilization efficiency.
