Description

Technical Field

[0001] The utility model 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 is a sterilization process that uses gasified disinfectants or radiation to sterilize packaging materials. It is a sterilization process for packaging materials with extremely low or no water content, with extremely low consumption of water and disinfectants, and cannot provide power for the movement of packaging materials. In order to prevent gasified disinfectants or radiation from harming operators and polluting the environment, this sterilization process requires sterilization of packaging materials in a closed environment, so it is necessary to separate the sterilization gas or radiation from the external space.

[0004] The cap 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 the sterilization efficiency and ensure the safety of aseptic filling production. A longer sterilization time requires a longer sterilization cap channel and sealing groove. Therefore, the dry sterilization cap channel of the cap is very long, which occupies a larger layout space. In addition, the dry sterilization process cannot provide power for the movement of the cap, so the existing dry cap sterilization device often adopts an inclined cap feeding structure or a star wheel to drive the cap at the front end. The inclined cap feeding structure has strict requirements on the inclination, which makes the layout more difficult. The setting of the star wheel will put forward 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, and when the cap has a small deformation, cap blocking will also occur.

[0005] It can be seen that in the dry sterilization device for the lid, the existing conveying device occupies a large space, has a difficult compact structure, is difficult to lay out, and has low conveying efficiency, and other problems need to be solved urgently. Utility Model Content

[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 a accommodating chamber 21 is arranged inside. A feed pipe 22 and a discharge pipe 23 are arranged on the sterilization box 2. 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 arranged in the accommodating chamber 21 with adjustable height and is provided with a spirally arranged partition 412. A conveying channel 411 for accommodating the cap body is formed between the partition 412 and 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 to the discharge pipe 23 along the conveying channel 411.

[0038] In this embodiment, the sterilization box 2 is arranged on the frame 1, which ensures that the cover can be effectively sterilized during the transportation process. The interior of the sterilization box 2 is provided with a receiving chamber 21, and the sterilization box 2 is provided with a feed pipe 22 and a discharge pipe 23. The receiving chamber 21 is connected to the outside through the feed pipe 22 and the discharge pipe 23, so that the cover can enter the receiving chamber 21 through the feed pipe 22 to receive the sterilization operation, and be discharged to the outside through the discharge pipe 23, thereby meeting the needs 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 receiving chamber 21, providing stable power for the transportation of the cover, which not only improves the working efficiency, but also facilitates the operation. The guide mechanism 4 includes a spiral disk 41, which is arranged in the receiving chamber 21 with adjustable height. The spiral disk 41 can be adjusted in height according to the specifications of the cover itself, so that the conveying channel 411 is more closely fitted to the cover for easy transportation. The spiral disk 41 is provided with a spirally arranged partition 412, and a conveying channel 411 for accommodating the cap body is formed between the partition 412 and the rotating disk 32, which helps to realize the orderly conveyance of a large number of cap bodies. The conveying channel 411 is connected to the feed pipe 22 and the discharge pipe 23. When the rotating disk 32 rotates, it can drive the cap body to be conveyed to the discharge pipe 23 along the conveying channel 411, which not only improves the reliability of the cap body conveyance, but also makes the entire cap conveying process smoother. Through the above-mentioned arrangement, the cap conveying device of this embodiment can efficiently and conveniently realize the cap body conveyance and sterilization treatment, and the structure is more compact.

[0039] Specifically, Figure 1As shown, the sterilization box 2 is provided with a maintenance port 24, and the sterilization box 2 includes a sealing cover 25 that can cover the maintenance port 24. By providing the maintenance port 24, the operator can conveniently clean, inspect or replace parts inside the sterilization box 2, thereby improving the maintainability of the equipment. At the same time, by providing the sealing cover 25, the sealing of the sterilization box 2 in the closed state is ensured, and external contaminants such as bacteria and dust are effectively prevented from entering the box, thereby ensuring the sterilization effect and product quality.

[0040] More specifically, the cover delivery device further includes a sealing member 5, which is sandwiched between the maintenance port 24 and the sealing cover 25, ensuring the sealing performance of the maintenance port 24 when closed, effectively preventing external impurities such as dust, moisture, etc. from invading the interior of the sterilization box 2, and at the same time, preventing the gas or substances in the sterilization box 2 from leaking into the external environment. In addition, the sealing member 5 can be made of sealant or a rubber ring to ensure the sealing performance of the accommodating cavity 21.

[0041] Specifically, 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 in the vertical direction, so that the power transmission of the cap feeding device is more direct and efficient. Through the power provided by the rotary driver 31, the turntable 32 can be stably and continuously rotated in the vertical direction, thereby realizing the smooth transportation of the cap body in the conveying channel 411. Among them, the rotary driver 31 can adopt a stepper motor or a servo motor, so that the operator can control the rotation speed of the turntable 32 through the rotary driver 31, which is conducive to improving the conveying efficiency and operation quality of the cap body.

[0042] Specifically, Figure 1-Figure 7 As shown, the turntable 32 is provided with a plurality of anti-slip holes 321 arranged at intervals, and the cover body is placed on the turntable 32. By increasing the friction between the turntable 32 and the cover body, the cover body is prevented from sliding off due to rotation or vibration during transportation, thereby improving the transportation quality of the cover body.

[0043] Specifically, Figure 1-Figure 3 As shown, the guide mechanism 4 further includes a hanger 42, which is disposed in the accommodating cavity 21 and connected to the spiral disk 41, so that the spiral disk 41 can operate stably in the accommodating cavity 21 to prevent it from shaking or shifting during operation, thereby ensuring the stable transmission of the cap body in the conveying channel 411. The hanger 42, the spiral disk 41 and the turntable 32 are arranged in sequence from top to bottom in the vertical direction, ensuring the reasonable layout of each component and a more compact structure, thereby improving the stability and smoothness of the cap delivery process.

[0044] More specifically, if Figure 1 and Figure 2As 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 can effectively disperse 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 failures and damage caused by eccentricity or misalignment, thereby ensuring the reliability and stability of the cap body transportation.

[0045] More specifically, 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, so as to ensure 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, for each support column, there are two adjusting nuts 6 screwed together, the spiral disk 41 is connected to the connecting frame, and the connecting frame is arranged between the two adjusting nuts 6 and connected to the support column. A stable clamping structure is formed by the two adjusting nuts 6. The connecting frame is located between the two adjusting nuts 6, which is not only convenient for adjusting the flatness of the connecting frame relative to the turntable 32, but also ensures the stable support of the spiral disk 41 to prevent it from shaking or shifting during operation. Moreover, by adjusting the two adjusting nuts 6 at the same time, the precise adjustment of the position of the connecting frame and the spiral disk 41 on the support column can be achieved, so as to facilitate the good transportation of covers of different specifications.

[0047] Specifically, Figure 1-Figure 6 As shown, a spiral partition 412 is provided on the spiral disk 41, and 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 is a spiral structure as a whole, which helps to realize the orderly conveying of the cover body. When the turntable 32 rotates, the cover body can abut against the partition 412, which can not only keep the position of the cover body in the conveying channel 411 stable, but also push the cover body forward. Through the above arrangement, when the cover body rotates with the turntable 32, it can gradually move toward the discharge pipe 23 along the spiral path, which not only improves the conveying efficiency, but also ensures the stability of the cover body during the conveying process.

[0048] Specifically, Figure 1-Figure 5As shown, the feed pipe 22 extends in the vertical direction, so that the cover body can directly and smoothly enter the conveying channel 411, 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 arranged 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 arranged downwardly, so that the cover body can slide out smoothly when leaving the conveying channel 411, thereby improving the discharge efficiency.

[0049] Specifically, the cap delivery device further includes an air extraction mechanism 7, the output end of which is connected to the feed pipe 22. Through the negative pressure generated by the air extraction mechanism 7, the cap can be effectively adsorbed and quickly delivered to the delivery channel 411, thereby avoiding the cap blocking phenomenon caused by friction or gravity. At the same time, it can also prevent the gasified disinfectant from overflowing through the feed pipe 22 to injure the operator and pollute the environment. Among them, the air extraction mechanism 7 can adopt a screw type air extraction pump or a centrifugal air extraction pump, and the specific principles thereof are clear to those skilled in the art, and will not be described in detail here.

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

[0051] First, the cover body is conveyed to the feed pipe 22 via an external conveying mechanism or manual operation by an operator, and the vacuum mechanism 7 is turned on. Through the negative pressure generated by the vacuum 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 to drive the turntable 32 to rotate in a 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 along the spiral path toward the discharge pipe 23 as the turntable 32 rotates. This conveying path is not only compact in structure and does not occupy 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 implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
