Description

Technical Field

[0001] The present invention relates to the technical field of aseptic filling, in particular to a cap feeding device. Background Art

[0002] With the development of aseptic production technology, various packaging material sterilization processes have emerged. Among them, the energy-saving and efficient dry sterilization process has been very popular in the market and has been widely used.

[0003] Dry sterilization uses vaporized disinfectants or radiation to sterilize packaging materials. This process requires very low or no water, consumes minimal water and disinfectant, and provides no power for moving the packaging. To prevent harm to operators and environmental contamination from vaporized disinfectants or radiation, this process requires sterilization of the packaging in a sealed environment, separating the sterilizing gas or radiation from the outside world.

[0004] The lid is an important packaging material in aseptic filling. It has threads and anti-theft barb structures that are difficult to sterilize. Therefore, no matter what sterilization process is used, a longer sterilization time is required to ensure sterilization efficiency and ensure the safety of aseptic filling production. The longer sterilization time requires a longer sterilization cap channel and sealing groove. Therefore, the dry sterilization cap channel of the lid is very long, which takes up a large layout space. In addition, the dry sterilization process cannot provide power for the movement of the lid. Therefore, existing dry cap sterilization devices often use an inclined cap feeding structure or a star wheel to drive the lid at the front end. The inclined cap feeding structure has strict requirements on the inclination, which makes the layout more difficult. The installation of a star wheel will place extremely high requirements on the processing accuracy of the cap groove. If the cap groove is too large or too small, it will cause cap blocking. Cap blocking will also occur when there is a slight deformation of the lid.

[0005] It can be seen that in the dry sterilization device for lids, the existing conveying device has the problems of large space occupation, difficult compact structure, difficult layout and low conveying efficiency, all of which need to be solved urgently. Summary of the Invention

[0006] The object of the present invention is to provide a cap feeding device that can efficiently and conveniently realize cap conveying and sterilization, and has a more compact structure.

[0007] To achieve this object, the present invention adopts the following technical solutions:

[0037] like Figure 1-Figure 7As shown, this embodiment provides a cap feeding device, which includes a frame 1, a sterilization box 2, a power mechanism 3 and a guide mechanism 4. The sterilization box 2 is arranged on the frame 1, and is provided with a accommodating chamber 21 inside. The sterilization box 2 is provided with a feed pipe 22 and a discharge pipe 23. The accommodating chamber 21 is connected to the outside through the feed pipe 22 and the discharge pipe 23. The power mechanism 3 includes a rotary driver 31 and a turntable 32. The rotary driver 31 is arranged on the frame 1 and can drive the turntable 32 to rotate in the accommodating chamber 21. The guide mechanism 4 includes a spiral disk 41. The spiral disk 41 is height-adjustable and is arranged in the accommodating chamber 21. It forms a conveying channel 411 for accommodating the cap body with the turntable 32. The conveying channel 411 is connected to the feed pipe 22 and the discharge pipe 23. When the turntable 32 rotates, it can drive the cap body to be conveyed along the conveying channel 411 to the discharge pipe 23.

[0038] In this embodiment, the sterilization box 2 is arranged on the frame 1, ensuring that the cover can be effectively sterilized during the transportation process. The interior of the sterilization box 2 is provided with a accommodating chamber 21, and the sterilization box 2 is provided with a feed pipe 22 and a discharge pipe 23. The accommodating chamber 21 is connected to the outside through the feed pipe 22 and the discharge pipe 23, so that the cover can enter the accommodating chamber 21 through the feed pipe 22 to undergo the sterilization operation, and be discharged to the outside through the discharge pipe 23, thereby meeting the requirements of aseptic filling production. The power mechanism 3 includes a rotary driver 31 and a turntable 32. The rotary driver 31 is arranged on the frame 1 and can drive the turntable 32 to rotate in the accommodating chamber 21, providing stable power for the transportation of the cover, which not only improves the working efficiency but also facilitates operation. The guide mechanism 4 includes a spiral disk 41, which is height-adjustably disposed within the accommodating chamber 21 and, together with the turntable 32, forms a conveying channel 411 for accommodating the lid. The spiral disk 41 can be height-adjusted according to the lid's specifications, allowing the conveying channel 411 to more closely fit the lid, facilitating transport. The conveying channel 411 is connected to the feed pipe 22 and the discharge pipe 23. When the turntable 32 rotates, it drives the lid along the conveying channel 411 to the discharge pipe 23, thereby improving the reliability of lid transport and facilitating the entire lid delivery process. Through the above-described arrangement, the lid delivery device of this embodiment can efficiently and conveniently achieve lid transport and sterilization, with a more compact structure.

[0039] Specifically, if Figure 1 As shown, the sterilization chamber 2 is provided with a maintenance port 24 and a sealing cover 25 that can be positioned over the maintenance port 24. The provision of the maintenance port 24 allows operators to conveniently clean, inspect, or replace components within the sterilization chamber 2, thereby improving the maintainability of the equipment. Furthermore, the provision of the sealing cover 25 ensures the airtight seal of the sterilization chamber 2 when closed, effectively preventing contaminants such as bacteria and dust from entering the chamber, thereby ensuring the sterilization effect and product quality.

[0040] More specifically, the cap feeding device further includes a sealing member 5, which is sandwiched between the maintenance port 24 and the sealing cover 25. This seal ensures the sealing performance of the maintenance port 24 when closed, effectively preventing external impurities such as dust and moisture from invading the interior of the sterilization chamber 2. It also prevents gases or substances within the sterilization chamber 2 from leaking into the external environment. Furthermore, the sealing member 5 can be made of sealant or a rubber ring to ensure the sealing of the accommodating chamber 21.

[0041] Specifically, if Figure 1 and Figure 2 As shown, the output end of the rotary driver 31 is connected to the turntable 32, which can drive the turntable 32 to rotate vertically, making the power transmission of the cap feeding device more direct and efficient. The power provided by the rotary driver 31 enables the turntable 32 to rotate stably and continuously in the vertical direction, thereby ensuring smooth conveyance of the caps in the conveying channel 411. The rotary driver 31 can be a stepper motor or a servo motor, allowing the operator to control the rotation speed of the turntable 32 through the rotary driver 31, which is beneficial for improving the conveying efficiency and operation quality of the caps.

[0042] Specifically, if Figure 1-Figure 7 As shown, the turntable 32 is provided with a plurality of anti-slip holes 321 spaced apart from each other. The cover is placed on the turntable 32 to increase the friction between the turntable 32 and the cover, thereby preventing the cover from sliding due to rotation or vibration during transportation, thereby improving the transportation quality of the cover.

[0043] Specifically, if Figure 1-Figure 3 As shown, the guide mechanism 4 further includes a hanger 42, which is disposed in the accommodating chamber 21 and connected to the spiral disk 41, enabling the spiral disk 41 to operate stably in the accommodating chamber 21 and preventing it from shaking or shifting during operation, thereby ensuring stable transportation of the caps in the conveying channel 411. The hanger 42, spiral disk 41, and turntable 32 are arranged in sequence from top to bottom in the vertical direction, ensuring a reasonable layout of the various components and a more compact structure, thereby improving the stability and smoothness of the cap feeding process.

[0044] More specifically, if Figure 1 and Figure 2 As shown, the hanger 42 includes a support column and a connecting frame. There are multiple support columns, which are arranged along the circumference of the connecting frame. The connecting frame is connected to the spiral disk 41, which not only ensures the stability of the hanger 42 in the horizontal direction, but also effectively disperses the weight and torque generated by the spiral disk 41. The two ends of the support column are respectively connected to the sterilization box 2 and the connecting frame to ensure the stability of the overall structure of the hanger 42. The spiral disk 41, the connecting frame and the turntable 32 are coaxially arranged, so that the cap feeding device can maintain stable rotation and conveying during the process of conveying the cap body, avoiding failure and damage caused by eccentricity or misalignment, thereby ensuring the reliability and stability of the cap body transportation.

[0045] More specifically, if Figure 1-Figure 3 As shown, the cap feeding device further includes an adjusting nut 6, which is screwed to the hanger 42. When the adjusting nut 6 is rotated, the height of the spiral disk 41 relative to the turntable 32 can be adjusted. By rotating the adjusting nut 6, the operator can fine-tune the height of the spiral disk 41, so that the cap feeding device can adapt to caps of different specifications and sizes, ensuring that the caps can smoothly enter the conveying channel 411 and be accurately conveyed to the designated position.

[0046] Specifically, if Figure 3 As shown, two adjusting nuts 6 are threaded onto each support column, and a spiral disk 41 is connected to a connecting frame. The connecting frame is positioned between the two adjusting nuts 6 and is also connected to the support column. The two adjusting nuts 6 form a stable clamping structure. The connecting frame, positioned between the two adjusting nuts 6, not only facilitates adjustment of the connecting frame's flatness relative to the turntable 32 but also ensures stable support for the spiral disk 41, preventing it from shaking or shifting during operation. Furthermore, by simultaneously adjusting the two adjusting nuts 6, the position of the connecting frame and the spiral disk 41 on the support column can be precisely adjusted, facilitating the smooth transport of lids of varying specifications.

[0047] Specifically, if Figures 1-6 As shown, a spirally arranged partition 412 is provided on the spiral disk 41. A conveying channel 411 is formed between the partition 412 and the turntable 32. One end of the conveying channel 411 is connected to the feed pipe 22, and the other end is connected to the discharge pipe 23. That is, the conveying channel 411 has an overall spiral structure, which helps to achieve orderly conveying of the cover body. When the turntable 32 rotates, the cover body can abut against the partition 412, which can not only maintain the position of the cover body in the conveying channel 411, but also push the cover body forward. Through this arrangement, the cover body can gradually move along the spiral path toward the discharge pipe 23 as the turntable 32 rotates, which not only improves the conveying efficiency but also ensures the stability of the cover body during the conveying process.

[0048] Specifically, if Figure 1-Figure 5 As shown, the feed pipe 22 extends in the vertical direction, allowing the cover body to enter the conveying channel 411 directly and smoothly, reducing the resistance of the cover body when entering the conveying channel 411, reducing the possibility of cover blockage, and improving the conveying efficiency of the cover feeding device. The connection between the feed pipe 22 and the conveying channel 411 is set in an arc shape, which can effectively guide the cover body to smoothly enter the conveying channel 411 from the feed pipe 22, avoiding the cover body from being stuck or damaged due to right-angle or acute-angle connection. At the same time, it can also reduce the accumulation of materials such as the cover body at the corners, further improving the smoothness of transportation. The discharge pipe 23 is set at an angle downward, allowing the cover body to slide out smoothly when leaving the conveying channel 411, improving the discharge efficiency.

[0049] Specifically, the cap delivery device also includes an air extraction mechanism 7, the output end of which is connected to the feed pipe 22. The negative pressure generated by the air extraction mechanism 7 effectively absorbs the cap and quickly feeds it into the delivery channel 411, avoiding cap blockage caused by friction or gravity. It also prevents the vaporized disinfectant from escaping through the feed pipe 22, potentially injuring operators and polluting the environment. The air extraction mechanism 7 can employ a screw pump or a centrifugal pump, and the specific principles are well known to those skilled in the art and will not be elaborated on here.

[0050] The specific working process of this device is described below:

[0051] First, the cover body is transported to the feed pipe 22 via an external conveying mechanism or manual operation by the operator, and the exhaust mechanism 7 is turned on. Through the negative pressure generated by the exhaust mechanism 7, the cover body can be effectively adsorbed and quickly fed into the conveying channel 411, and then the rotation driver 31 is started, thereby driving the turntable 32 to rotate in the vertical direction. Since a plurality of anti-slip holes 321 arranged at intervals are provided on the turntable 32, and the cover body is placed on the turntable 32, friction is generated between the cover body and the turntable 32, so that the cover body can move along the spirally arranged conveying channel 411 and continuously toward the discharge pipe 23 as the turntable 32 rotates until it is discharged from the discharge pipe 23 and enters the next process.

[0052] It should be noted that the cover feeding device of this embodiment forms a spiral conveying channel 411 between the spiral disk 41 and the turntable 32, so that the cover body can gradually move toward the discharge pipe 23 along the spiral path as the turntable 32 rotates. The conveying path is not only compact in structure and does not take up too much space, but also can improve the conveying efficiency of the cover body.

[0053] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here.
