Description

Technical Field

[0001] This utility model relates to the field of wet wipe processing technology, specifically a wet wipe capping machine for wet wipe processing. Background Technology

[0002] Wet wipes are personal care products that provide skin cleaning and disinfection in the form of moistened paper towels. Made from non-woven fabric as the carrier material and infused with functional liquids, they are widely used for daily cleaning and carrying when out and about. To ensure the wet wipe packaging is airtight, the wipe bag usually has an openable plastic cap. During production, a wet wipe capping machine is needed to attach the caps. Traditional wet wipe capping machines often use spider robots for this task. In operation, a cap conveyor line transports the caps to the spider robot, which then uses suction cups to pick them up. The robot first picks up the wet wipe cover, then moves it to the top of the adhesive applicator. The applicator applies adhesive to the bottom of the wet wipe cover. Then, the spider-arm robot moves the adhesive-coated wet wipe cover to the top of the wet wipe bag and presses the wet wipe cover onto the wet wipe bag, completing the wet wipe capping process. Traditional wet wipe capping machines use spider-arm robots to perform the wet wipe capping work. The spider-arm robot needs to complete the tasks of picking up the cover, applying adhesive, and capping in sequence, which takes a long time and results in low wet wipe capping efficiency. In addition, the equipment and maintenance costs of spider-arm robots are high. Therefore, we propose a wet wipe capping machine for wet wipe processing. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a wet wipe capping machine for wet wipe processing. It is equipped with a rotatable and circulating capping mechanism, which has a simple structure and low cost. It can also perform cap removal and adhesive application while capping, thereby improving the capping efficiency of wet wipes and effectively solving the problems in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a wet wipe capping machine for wet wipe processing, comprising a capping shell and a capping mechanism; Cover shell: A mounting column is rotatably connected to the middle of its top wall, and mounting brackets are provided at the four corners of the lower end of the outer surface of the mounting column; The cap-applying mechanism includes a sliding column, a suction cup, a spring, a limiting block, and a drive assembly. The sliding columns are all slidably connected to the inside of the mounting frame. The suction cups are all located at the lower end of the sliding columns. The limiting blocks are all bolted to the middle of the outer surface of the sliding columns. Springs are provided between the lower end of the limiting blocks on the outer surface of the same sliding column and the bottom wall of the vertically adjacent mounting frame. The springs are all sleeved on the outer surface of the sliding column, providing a basis for the placement and movement of the wet wipe cap. The drive assembly is located at the upper inside of the cap-applying shell and has a rotatable and cyclical cap-applying mechanism. The structure is simple and low-cost. It can remove the cap and apply adhesive while applying the cap, improving the efficiency of cap-applying wet wipes.

[0005] Furthermore, the driving component includes an electric push rod, which is located at the middle of the upper front side of the cover. The input end of the electric push rod is electrically connected to the output end of the microcontroller. The upper end of the slide column is installed in conjunction with the lower end of the telescopic end of the electric push rod, providing a driving effect for the application of the wet wipe cover.

[0006] Furthermore, the drive assembly also includes a limiting ball, which is located in the middle of the right side of the top wall of the cover. The upper ends of the sliding columns are all fitted with the lower ends of the limiting ball to provide a limiting effect for the removal of the wet wipe cover.

[0007] Furthermore, the drive assembly also includes a gear, an external gear ring, and a motor. The gear is rotatably connected to the front middle of the top wall of the cover shell. The external gear ring is fixedly sleeved on the upper outer surface of the mounting post. The gear and the external gear ring are meshed together. The motor is located on the front middle of the upper end of the cover shell. The input end of the motor is electrically connected to the output end of the microcontroller. The lower end of the motor's output shaft is fixedly connected to the upper end of the gear, providing a basis for the rotation of the mounting post and mounting bracket.

[0008] Furthermore, the cover-applying mechanism also includes an adhesive extrusion block and an adhesive dispensing head. The adhesive extrusion block is located in the middle of the rear side of the bottom wall of the cover, and the adhesive dispensing head is evenly distributed at the upper end of the adhesive extrusion block, providing a basis for the adhesive application of the wet wipe cover.

[0009] Furthermore, it also includes a vision camera, which is located on the front left side of the top wall of the cover. The vision camera is bidirectionally electrically connected to the microcontroller to provide visual monitoring for the application of the wet wipes.

[0010] Furthermore, it also includes a microcontroller, which is placed on the right side of the cover. The input terminal of the microcontroller is electrically connected to an external power supply to provide control for the application of the wet wipe cover.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This wet wipe applicator has the following advantages: The entire mechanism consists of common equipment, resulting in low equipment and maintenance costs. The meshing of gears and external gear rings drives the mounting column and mounting bracket to rotate counterclockwise, causing the sliding column to cycle counterclockwise. Combined with the limiting ball's positioning, the glue dispensing head's extrusion, and the electric push rod's squeezing, the sliding column sequentially passes through three stations: cap removal, glue dispensing, and cap application. The actions at these three stations are performed simultaneously, enabling cap application while simultaneously removing and applying glue. This improves the efficiency of wet wipe cap application and avoids the situation in traditional spider-arm robots where cap removal, glue application, and cap application are performed sequentially, reducing the cap application cycle time and increasing the efficiency of wet wipe cap application.

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-4 This embodiment provides a technical solution: a wet wipe capping machine for wet wipe processing, including a capping shell 1 and a capping mechanism 4; Cover shell 1: A mounting column 2 is rotatably connected to the middle of its top wall. A central shaft is provided in the middle of the top wall of the cover shell 1. Bearings are evenly distributed between the central shaft and the mounting column 2. The inner wall of the bearing ring is fixedly connected to the outer surface of the central shaft. The outer surface of the bearing ring is fixedly connected to the inner wall of the mounting column 2. Mounting brackets 3 are provided at the four corners of the lower end of the outer surface of the mounting column 2. It also includes a vision camera 5. The vision camera 5 is located at the front left side of the top wall of the cover shell 1. The vision camera 5 is bidirectionally electrically connected to the microcontroller 6 to provide visual monitoring for the application of the wet wipes. It also includes a microcontroller 6. The microcontroller 6 is placed on the right side of the cover shell 1. The input end of the microcontroller 6 is electrically connected to an external power supply to provide control for the application of the wet wipes. The cover-applying mechanism 4 includes sliding columns 41, suction cups 42, springs 43, limiting blocks 44, and a drive assembly 45. The sliding columns 41 are slidably connected to the interior of the mounting frame 3. The suction cups 42 are all located at the lower end of the sliding columns 41 and are connected to an external air compressor via air pipes. A rotary joint is connected in series in the middle of the air pipes and is located at the lower end of the central shaft. The lower end of the rotating end of the rotary joint is fixedly connected to the bottom wall of the mounting column 2. The limiting blocks 44 are bolted to the middle of the outer surface of the sliding columns 41. Springs 43 are provided between the lower end of each limiting block 44 located on the outer surface of the same sliding column 41 and the bottom wall of the vertically adjacent mounting frame 3. The springs 43 are all sleeved on the outer surface of the sliding columns 41. The limiting blocks 44 can be removed by tightening or loosening the bolts. Afterwards, the sliding column 41 can slide downwards out of the mounting bracket 3, facilitating the replacement of the spring 43 and preventing the spring 43 from aging after long-term use. This provides a basis for the placement and movement of the wet wipe cover. The drive assembly 45 is located inside the upper part of the cover shell 1. The drive assembly 45 includes an electric push rod 451, which is located in the middle of the front side of the upper end of the cover shell 1. The input end of the electric push rod 451 is electrically connected to the output end of the microcontroller 6. The upper end of the sliding column 41 is installed in conjunction with the lower end of the telescopic end of the electric push rod 451. After the lower end of the telescopic end of the electric push rod 451 extends, it can press the sliding column 41 downwards. Limiting rods are provided on both the front and rear sides of the upper end of the telescopic end of the electric push rod 451. The outer surface of the limiting rods is slidably connected to the inside of the top wall of the cover shell 1, which is the electric push rod. The vertical movement of the telescopic end 451 provides a limiting effect, ensuring that the axial load is the main load when the electric push rod 451 is working, while the radial load is greatly reduced due to the limiting of the limiting rod, making it less prone to damage. This provides a driving effect for the application of the wet wipe cover. The drive assembly 45 also includes a limiting ball 452, which is located in the middle of the right side of the top wall of the cover-applying shell 1. The upper ends of the sliding columns 41 are all fitted with the lower ends of the limiting ball 452. The limiting ball 452 can squeeze the passing sliding columns 41, causing the sliding columns 41 to move downward under force. The limiting ball 452 is a common universal ball structure in the prior art, providing a limiting effect for the removal of the wet wipe cover. The drive assembly 45 also includes a gear 453, an external gear ring 454, and a motor 455. The gear 453 is rotatably connected to the top wall of the cover-applying shell 1. On the front side of the middle, an external gear ring 454 is fixedly sleeved on the upper part of the outer surface of the mounting post 2. A gear 453 meshes with the external gear ring 454. A protective cover is provided in the middle of the top wall of the cover shell 1. Both the gear 453 and the external gear ring 454 are located inside the protective cover. A motor 455 is located on the front side of the upper end of the cover shell 1. The input end of the motor 455 is electrically connected to the output end of the microcontroller 6. The lower end of the output shaft of the motor 455 is fixedly connected to the upper end of the gear 453, providing a foundation for the rotation of the mounting post 2 and the mounting bracket 3. The cover-applying mechanism 4 also includes an extrusion block 46 and an extrusion head 47. The extrusion block 46 is located in the middle of the rear side of the bottom wall of the cover shell 1. The extrusion block 46 is fixedly connected to the middle of the rear side of the bottom wall of the cover shell 1 by screws. The extrusion heads 47 are evenly distributed on the upper end of the extrusion block 46.The extrusion block 46 can be replaced according to actual needs. Different extrusion blocks 46 have different numbers and arrangements of adhesive nozzles 47, adapting to the adhesive application of different wet wipe caps. This provides a foundation for the adhesive application of wet wipe caps. A rotating, circulating cap-applying mechanism 4 is included, featuring a simple structure and low cost. It can simultaneously apply and remove caps, improving the efficiency of wet wipe cap application.

[0016] The working principle of the wet wipe capping machine provided by this utility model is as follows: Before capping the wet wipes, the equipment is first placed. The first external conveyor line for conveying the wet wipe bag is set on the front side of the bottom wall of the capping shell 1, so that the first external conveyor line passes through the capping shell 1. The wet wipe bag belt can move along the front side of the bottom wall of the capping shell 1. The vision camera 5 can monitor the status of the wet wipe bag passing below in real time. The first external conveyor line is vertically adjacent to the sliding column 41 on the front side. The second external conveyor line for conveying the wet wipe cap is set on the right side of the middle of the bottom wall of the capping shell 1, so that the second external conveyor line is vertically adjacent to the sliding column 41 on the right side. Then, the microcontroller 6 controls the motor 455 to run. The output shaft of the motor 455 drives the gear 453 to rotate, and the external gear ring 454 also rotates accordingly. The motor 455 stops running every 90 degrees as the mounting column 2 and mounting bracket 3 rotate counterclockwise, providing a pause for the sliding column 41 at each station. The entire equipment continuously cycles counterclockwise during the capping operation, with simultaneous actions at the front, right, and rear stations. The sliding column 41 performs a corresponding action each time it moves to a station. When the sliding column 41 moves to the right, the limit ball 452 presses against the upper end of the sliding column 41, causing it to move downwards. The spring 43 contracts under pressure, and as the sliding column 41 moves downwards, the suction cup 42 also moves downwards. At this point, the suction cup 42 is about to contact the wet wipe cap on the external conveyor line 2. The external air compressor operates, and the suction cup 42 firmly holds the wet wipe cap. After the cap removal is completed, as the mounting column 2 rotates, the suction cup 42 deflects the wet wipe cap backward. When the sliding column 41 passes the limit ball 452, the upper end of the sliding column 41 is no longer under force, and the spring 43 expands, causing the sliding column 41 to return to its original position. When the sliding column 41 deflects backward, the wet wipe cap covers the upper end of the extrusion block 46, and the lower end of the wet wipe cap is about to contact the upper end of the dispensing head 47. The external extrusion device works, and the adhesive is squeezed out from the dispensing head 47. (The extrusion block 46 has a hollow structure, and the dispensing heads 47 on the upper surface of the extrusion block 46 are distributed according to the shape of the wet wipe cap. The extrusion block 46 is connected to an external pumping device, such as the glue pump commonly used in the prior art. The extrusion block 46 is connected to the dispensing head 47 on the upper surface, and the external pumping device...) The pump pressurizes the adhesive through the extrusion block 46 and the dispensing head 47, squeezing the adhesive out from the dispensing head 47. The adhesive then adheres evenly to the lower end of the wet wipe cover, completing the adhesive application. The slide column 41 continues to rotate to the left. When the slide column 41 reaches the left side, it stops moving, while slide columns 41 at other stations perform their corresponding actions. The slide column 41 then continues to rotate forward. When the slide column 41 reaches the front, the microcontroller 6 controls the electric push rod 451 to operate. The telescopic end of the electric push rod 451 extends downwards, squeezing the upper end of the slide column 41. The upper end of the slide column 41 is under pressure, causing it to move downwards. The spring 43 contracts under pressure. As the slide column 41 moves downwards, the lower end of the wet wipe cover, already adhesive, below the suction cup 42 contacts the upper end of the wet wipe bag on the external conveyor line.The pressure generated by the downward movement of the sliding column 41 allows the wet wipe cap to adhere tightly to the top of the wet wipe bag, completing the cap application. At this time, the external air compressor operates, the suction cup 42 releases the wet wipe cap, and then the telescopic end of the electric push rod 451 retracts. The spring 43, no longer under force, moves the sliding column 41 upward, completing the entire wet wipe cap application process. The sliding column 41 then continues to rotate, sequentially performing cap removal, adhesive application, and cap application, repeating this process.

[0017] It is worth noting that the microcontroller 6 disclosed in the above embodiments is an STM32L011D4 microcontroller, the electric actuator 451 is a BHLK-01 electric actuator, the motor 455 is a 1FT7136-5AC71-1MA1 motor, and the vision camera 5 is a DataMan 8072V vision camera. The microcontroller 6 controls the operation of the electric actuator 451, the motor 455, and the vision camera 5 using methods commonly used in the prior art.
