Description

Technical Field

[0001] This application relates to the field of wet wipe packaging technology, and in particular to an automatic capping machine for wet wipe production. Background Technology

[0002] In the wet wipes manufacturing industry, in order to meet the requirements of product packaging airtightness and ease of use, wet wipes are usually packaged in the form of plastic bags with flip-tops. This packaging method protects the wet wipes from contamination while making it convenient for consumers to open and reseal them when using them.

[0003] In the existing wet wipes production process, after the wet wipes are packaged in paper bags, some capping is done manually in conjunction with the assembly line. Specifically, on the assembly line, the packaged wet wipe bags move along the conveyor belt, and workers need to stand beside the line, pick up the cap, and press it onto the opening of the plastic bag. Due to the speed limitations of manual operation, workers cannot complete the capping action as quickly and continuously as machines. Over long periods of work, the operating speed also slows down, affecting overall production efficiency.

[0004] To address the aforementioned issues, an automatic capping machine for wet wipe production has been designed. Utility Model Content

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0019] This application provides an automatic capping machine for wet wipe production, which can solve the problem in related technologies where manual capping is performed by workers in conjunction with the production line after the wet wipes have been packaged in paper bags, which reduces production efficiency.

[0020] Please see Figures 1-3An automatic capping machine for wet wipe production includes: a first conveyor line 1 and a second conveyor line 2 arranged side by side, wherein the first conveyor line 1 is used to convey box caps and the second conveyor line 2 is used to convey packaged wet wipe bags; A capping mechanism 3 is disposed between conveyor line 1 and conveyor line 2 and is used to press the lid onto the wet wipe packaging bag. The capping mechanism 3 includes a frame 31, a drive component 32 mounted on the frame 31, a lifting component 33 connected to the drive component 32, and a pneumatic suction cup 34 mounted on the lifting component 33. The pneumatic suction cup 34 is used to adsorb the lid, the lifting component 33 is used to drive the pneumatic suction cup 34 to rise and fall, and the drive component 32 is used to drive the pneumatic suction cup 34 to reciprocate above the conveyor line 1 and the conveyor line 2.

[0021] Conveyor line 1 and conveyor line 2, which are set up side by side, start running.

[0022] Conveyor line 1 is responsible for continuously and stably conveying the box lid forward, while conveyor line 2 synchronously conveys the packaged wet wipe bags, so that the box lid and wet wipe bags move in the predetermined direction on their respective conveyor lines.

[0023] When the lid on conveyor line 1 reaches the appropriate position, the capping mechanism 3 starts working. The drive unit 32 on the frame 31 is activated, driving the lifting unit 33 connected to it to move. This moves the pneumatic suction cup 34, which is mounted on the lifting unit 33, to directly above the lid on conveyor line 1. Subsequently, the lifting unit 33 drives the pneumatic suction cup 34 to descend until it makes tight contact with the lid. At this point, the pneumatic suction cup 34 firmly holds the lid in place through the negative pressure generated inside.

[0024] After the lid is attached, the lifting component 33 drives the pneumatic suction cup 34 to rise, lifting the lid and removing it from the conveyor line 1. Then, the driving component 32 moves again, moving the pneumatic suction cup 34 with the lid attached to it to the top of the wet wipe packaging bag above the conveyor line 2.

[0025] Once the pneumatic suction cup 34, carrying the lid, reaches the appropriate position directly above the wet wipes packaging bag, the lifting component 33 drives the pneumatic suction cup 34 to descend, accurately pressing the lid onto the opening of the wet wipes packaging bag.

[0026] Afterwards, the pneumatic suction cup 34 stops adsorbing, releasing the suction force on the lid. The lifting component 33 then drives the pneumatic suction cup 34 to rise and reset, completing one capping operation. The entire process is repeated cyclically, achieving continuous automatic capping of wet wipe packaging bags.

[0027] Through the coordinated operation of conveyor line 1, conveyor line 2, and capping mechanism 3, the fully automated operation of lid conveying, adsorption, transfer, and pressing is achieved. Compared with the traditional manual capping method, the time required for each capping cycle is greatly shortened. The machine can work continuously without interruption, improving the overall production efficiency of the wet wipes production line and meeting the needs of large-scale production.

[0028] Since the entire capping process is completed automatically by machine, it does not require a large amount of manual labor, thus reducing labor costs.

[0029] It should be noted that sensors are installed on both conveyor line 1 and conveyor line 2 in this embodiment, as well as a controller installed on conveyor line 1.

[0030] On conveyor line 1, as the lid moves forward with the conveyor belt 14, the sensor installed on conveyor line 1 starts to work. The sensor can monitor the position information of the lid in real time. When the lid reaches the detection area set by the sensor, the sensor will convert this signal into an electrical signal.

[0031] The sensor rapidly transmits the detected electrical signal to the controller's control system. Upon receiving the signal, the control system analyzes and processes it, then sends a command to the capping mechanism 3. The drive unit 32 in the capping mechanism 3 activates according to the command, driving the lifting unit 33 to move, causing the pneumatic suction cup 34 to move directly above the lid on conveyor line 1. Subsequently, the lifting unit 33 drives the pneumatic suction cup 34 downwards, where it uses negative pressure to grip the lid. Then, the lifting unit 33 drives the pneumatic suction cup 34 upwards again, completing the lid-grabbing action.

[0032] Meanwhile, on conveyor line 2, the packaged wet wipe bags also move forward under the drive of the conveyor belt. Sensors installed at corresponding positions on conveyor line 2 also monitor the position of the wet wipe bags in real time. When a wet wipe bag reaches the detection point set by the sensor, the sensor sends a signal and transmits it to the control system.

[0033] Based on the signal from conveyor line 2, the control system commands the drive unit 32 of the capping mechanism 3 to operate again, moving the pneumatic suction cup 34 carrying the lid to directly above the wet wipe packaging bag above conveyor line 2. Then, the lifting unit 33 drives the pneumatic suction cup 34 to descend, accurately pressing the lid onto the wet wipe packaging bag. After capping is completed, the pneumatic suction cup 34 releases its suction, rises to its original position, and awaits the next gripping and capping operation.

[0034] Furthermore, the sensor in this embodiment is a photoelectric sensor or a position sensor. The photoelectric sensor can detect the presence, position, and passing status of an object, and is used to monitor the position of the box lid and wet wipe packaging bag on the conveyor line. For example, the SICK W26 can perform stable detection of cartons and flexible packaging.

[0035] The position sensor can accurately detect the position information of the object, providing accurate operational basis for the capping mechanism 3. Position sensors include various types; among them, inductive position sensors can be selected according to actual needs to ensure accurate detection of the position of the lid and the wet wipe packaging bag. This is existing technology and will not be elaborated upon here.

[0036] like Figure 1 and Figure 5 As shown, in this embodiment, both conveyor line 1 and conveyor line 2 include: a frame 11; two drive rollers 13 rotatably mounted on a side plate 12 mounted on the frame 11; a conveyor belt 14 driven outside the two drive rollers 13; and a drive unit 15 mounted on the side plate 12. The drive unit 15 is connected to one of the drive rollers 13 and is used to drive the drive roller 13 to rotate. The drive unit includes a drive motor and a reducer. The output shaft of the drive motor is connected to the input shaft of the reducer, and the output shaft of the reducer is connected to one end of any drive roller 13.

[0037] The drive motors of the drive units 15 of conveyor line 1 and conveyor line 2 are started, and their output shafts begin to rotate, transmitting power to the reducer.

[0038] The reducer adjusts the input rotational speed, decreasing the rotational speed according to a preset reduction ratio while increasing the torque. The adjusted power is then transmitted to the drive roller 13 via its output shaft. The drive roller 13, receiving power output, begins to rotate. Since the two drive rollers 13 are relatively rotated on the side plate 12, and the conveyor belt 14 is driven outside the two drive rollers 13, the rotating drive rollers 13 drive the conveyor belt 14 through friction. The conveyor belt 14 forms a continuous cyclic motion path between the two drive rollers 13.

[0039] For conveyor line 1, the lid is placed on conveyor belt 14, and the lid is smoothly conveyed forward as conveyor belt 14 circulates. For conveyor line 2, the packaged wet wipes bag is placed on conveyor belt 14, and the wet wipes bag moves along conveyor line 2 under the drive of conveyor belt 14.

[0040] like Figure 1 and Figure 2 As shown, in one embodiment, a guide plate 4 is provided above the conveyor line 1. One end of the guide plate 4 is arc-shaped, and the guide plate 4 and the conveyor line 1 enclose a guide channel 41 for conveying the box cover.

[0041] The guide plate 4 is made of polyethylene (PE), which has the advantages of good chemical stability, acid and alkali resistance, and low cost.

[0042] During installation, use a level to check the horizontality of the guide plate 4 to ensure it is not tilted in the horizontal direction. Adjust the distance between the guide plate 4 and the conveyor line 1 according to the thickness of the lid and the conveying requirements, so that the height of the guide channel 41 is just large enough to accommodate the lid's passage, with a certain gap to avoid excessive friction between the lid and the guide plate 4. Precise measurement and adjustment can be performed using tools such as feeler gauges.

[0043] In addition, ensure that the arc-shaped end of the guide plate 4 is aligned with the starting end of the conveyor line 1 so that the lid can smoothly enter the guide channel 41. The position of the arc-shaped end can be fine-tuned by simulating the lid conveying process and observing the lid's entry into the guide channel 41.

[0044] The guide channel 41 formed by the guide plate 4 can constrain the movement direction of the lid, reduce the offset and shaking of the lid during the conveying process, and enable the lid to reach the designated position quickly and accurately. This provides favorable conditions for the gripping and pressing operation of the pressing mechanism 3, reduces the repetitive operation time caused by inaccurate lid position, and thus improves production efficiency.

[0045] like Figure 1 and Figure 2 As shown, in one embodiment, a limit mechanism 5 is provided on the second conveyor line 2; The limiting mechanism 5 includes multiple columns 51 arranged opposite to each other on both sides of the second conveyor line 2. A fixing rod 52 is inserted into each column 51. A guide plate 53 is provided at the same end of the multiple fixing rods 52 on the same side. The two guide plates 53 are arranged opposite to each other. There is a gap between the bottom of the guide plate 53 and the conveyor belt 14 of the second conveyor line 2.

[0046] When the wet wipe packaging bag is placed on the conveyor line 2 and begins to be conveyed, as the conveyor belt 14 moves, the wet wipe packaging bag gradually approaches the limiting mechanism 5.

[0047] Since the two guide plates 53 are positioned opposite each other on both sides of the conveyor line 2, a narrowing guide channel is formed.

[0048] As the wet wipe packaging bag enters the guide channel, the guide plates 53 on both sides exert a lateral restraining force on it. This restraining force will cause the wet wipe packaging bag to gradually move towards the center of the channel, thereby correcting its offset position and making it stably transported along the center line of the second conveyor line 2. During this process, the wet wipe packaging bag maintains the correct position and posture as it passes through the limiting mechanism 5 under the guidance of the guide plates 53.

[0049] The distance between the bottom of the guide plate 53 and the conveyor belt 14 ensures that the wet wipe packaging bag can move smoothly on the conveyor belt 14, while avoiding excessive friction between the guide plate 53 and the conveyor belt 14, which would affect the normal operation of the conveyor belt 14.

[0050] like Figure 1 and Figure 3 As shown, in one embodiment, the driving component 32 includes a rectangular frame 321 mounted on a frame 31. The rectangular frame 321 is arranged along the width of conveyor line 1 and conveyor line 2. A slide block 322 is slidably mounted on one side of the rectangular frame 321. The slide block 322 is U-shaped. A connector 323 is mounted on the other side of the slide block 322. A cylinder 324 is mounted at one end of the rectangular frame 321. The piston rod of the cylinder 324 is connected to the connector 323.

[0051] The rectangular frame 321 is arranged along the width direction of conveyor line 1 and conveyor line 2, so that the length direction of the drive component 32 is consistent with the width direction of the conveyor line, which facilitates providing a stable sliding track for the slide 322.

[0052] When it is necessary to drive the slide block 322 to move in a certain direction, the control system sends a signal to the control valve of the cylinder 324, so that compressed air enters one of the air chambers of the cylinder 324, pushing the piston to extend outward. The piston drives the connecting member 323 to move through the piston rod, and the connecting member 323 then transmits the force to the slide block 322, so that the slide block 322 slides along the rectangular frame 321 in the specified direction.

[0053] When the slide block 322 completes a working stroke and needs to return, the control system changes the state of the control valve of the cylinder 324, allowing compressed air to enter another chamber of the cylinder 324, while simultaneously expelling the compressed air from the previous chamber. At this time, the piston retracts under the action of air pressure, and through the piston rod and connecting piece 323, it drives the slide block 322 to slide in the opposite direction along the rectangular frame 321, returning to the initial position, thereby controlling the slide block 322 to reciprocate along the width of conveyor line 1 and conveyor line 2.

[0054] like Figure 1 and Figure 3 As shown, in one embodiment, the lifting member 33 includes a vertical plate 331 disposed on a slide block 322, a second cylinder 332 disposed on the vertical plate 331, two guide rails 333 disposed opposite to each other on the vertical plate 331, a moving block 334 slidably disposed between the two guide rails 333, the bottom end of the piston rod of the second cylinder 332 being connected to the moving block 334; and a fixed seat 335 disposed on the moving block 334.

[0055] When it is necessary to control the fixed seat 335 to rise, the control system sends a signal to the control valve of cylinder 332, so that compressed air enters the upper air chamber of cylinder 332 and at the same time discharges the compressed air in the lower air chamber. At this time, the piston retracts upward under the action of air pressure, and drives the moving block 334 to slide upward along the guide rail 333 through the piston rod, thereby driving the fixed seat 335 and the components installed on it to rise.

[0056] When the control component needs to be lowered, the control system changes the state of the control valve of cylinder 2 332, allowing compressed air to enter the lower air chamber of cylinder 2 332, while simultaneously expelling the compressed air from the upper air chamber. Under the action of air pressure, the piston extends downward, and through the piston rod, it drives the moving block 334 to slide downward along the guide rail 333, causing the fixed seat 335 and the components mounted on it to descend.

[0057] Two opposing guide rails 333 provide guidance for the moving block 334, so that the moving block 334 can only move vertically along the guide rails 333 during the lifting process, reducing the shaking and deviation during the movement and ensuring the smoothness of the movement of the lifting component 33.

[0058] like Figure 1 and Figure 3 As shown, the pneumatic suction cup 34 includes a mounting bracket 341 mounted on a fixed base 335. The mounting bracket 341 is provided with four flat suction cups 342 arranged in a rectangular shape. The flat suction cups 342 are connected to an external pneumatic vacuum device through pipes.

[0059] Mounting bracket 341 is the basic support structure for pneumatic suction cup 34, providing a stable mounting platform for flat suction cup 342.

[0060] The flat suction cup 342 is a common type of pneumatic suction cup. Its flat shape and large adsorption area allow it to provide strong suction when adsorbing objects with flat surfaces. It can also better adapt to the surface shape of objects and reduce air leakage.

[0061] The piping uses a rubber hose to connect the flat suction cup 342 to an external pneumatic vacuum device, forming a complete pneumatic system. The negative pressure generated by the pneumatic vacuum device is transmitted to the flat suction cup 342 through the rubber hose, creating a vacuum inside the suction cup and thus generating suction force. At the same time, when it is necessary to release an object, external air is introduced into the suction cup to eliminate the vacuum and allow the object to detach from the suction cup.

[0062] Specifically, when an object needs to be adsorbed, an external pneumatic vacuum device activates, extracting air from the flat suction cup 342 through a pipe, creating a negative pressure inside the suction cup. Due to the atmospheric pressure outside the suction cup, the object is pressed tightly onto the flat suction cup 342, thus achieving the adsorption function. The simultaneous operation of four rectangularly distributed flat suction cups 342 provides uniform adsorption force, ensuring the object remains stable during the adsorption process.

[0063] When it is necessary to release the adsorbed object, the pneumatic vacuum device stops pumping air and introduces external air into the flat suction cup 342 through the pipe, so that the pressure inside the suction cup is equal to the external atmospheric pressure, and the object is released from the suction cup under its own weight or other external forces.

[0064] It should be noted that pneumatic vacuum equipment includes: a vacuum pump: which directly evacuates air using mechanical means such as vanes, Roots pumps, or liquid ring pumps to create a high vacuum; a solenoid valve: which controls the on / off flow of compressed air to achieve rapid vacuum establishment and release; a vacuum pressure switch: which monitors the vacuum level and sends a signal when a set value is reached to ensure adsorption reliability; a check valve: which prevents vacuum leakage and maintains system stability; a filter: which removes moisture and impurities from the compressed air, protecting the vacuum generator and suction cups; an air tank: which stabilizes the compressed air pressure and reduces the impact of fluctuations on the system; and pipes and fittings, which are existing technologies and will not be described further here.
