Description

Technical Field

[0001] The present invention relates to the technical field of wet wipe production, and particularly relates to a three-row synchronous automatic packaging system for wet wipes. Background Art

[0002] In the field of personal care and hygiene products, the market demand for wet wipes shows a continuous growth trend. From daily cleaning to hygiene maintenance in special scenarios, wet wipes are widely used in many industries such as household, medical, catering, and tourism due to their convenience and practicality. To meet the growing market demand for wet wipes and improve production efficiency, the research and innovation of automatic wet wipe production lines are crucial.

[0003] With the increasing market demand for wet wipes, how to improve production capacity is an urgent problem to be solved at present. At present, the production of wet wipes has transitioned from traditional semi-automatic production to fully automatic production. To improve production capacity, it mainly starts from two aspects. One is to expand the production line, and the other is to improve the production efficiency of the production line.

[0004] Expanding the production line is the most direct way to increase production capacity. However, expanding the production line means that new equipment needs to be purchased, the factory building needs to be expanded, etc., and the investment is too large, which is difficult for many enterprises to afford. The increase in cost is also likely to affect the product pricing and is not conducive to the development of the enterprise.

[0005] Therefore, the best solution is to improve the production efficiency of the production line. In this way, the production capacity can be increased without or with less expansion of the enterprise.

[0006] The invention patent with the application number 2021112365105 discloses an automatic wet wipe production line. This patent is the patent of our company's previous generation of products. This solution can run synchronously in two lines, producing two packs of wet wipes at a time, improving production efficiency. In addition, during the process of conveying the wet wipe raw materials, the wet wipe raw materials can first enter the cutting system to form single wet wipes, and then pass through the humidifying system. When conveying the single wet wipes, it can avoid pulling the humidified wet wipe raw materials, thereby avoiding the situation of pulling and breaking of the humidified wet wipe raw materials.

[0007] In order to further increase the output of wet wipes, our company then began to research and develop a three-row synchronous automatic production line. However, after changing the two-row production line to a three-row production line, many problems have emerged. Wet wipe packaging is one of the main problems. We found that when the width of the packaging bag sealing mechanism is widened, there is a certain probability that the middle wet wipe line will have the problem of incomplete sealing during the packaging process, seriously affecting the product yield. Summary of the Invention

[0008] The present invention provides a three-row synchronous automatic packaging system for wet wipes to solve the technical problem of the reduced packaging yield of three rows of wet wipes in the prior art.

[0009] To solve the above problems, the three-row synchronous automatic packaging system for wet wipes provided by the present invention adopts the following technical solutions: It includes a feeding and conveying mechanism, which is used to convey the unpacked stacked wet wipes, and the direction of wet wipe movement is defined as the right side;

[0010] A lifting mechanism, which is used to lift the wet wipes, and the lifting mechanism is arranged at the end of the feeding and conveying mechanism;

[0011] A pushing mechanism, which includes a push rod that can slide in the left-right direction, and the pushing mechanism is used to push the wet wipes into the packaging bag, and the pushing mechanism is arranged above the feeding and conveying mechanism;

[0012] A bag-taking mechanism, which is used to take the packaging bag and keep the packaging bag open so that the pushing mechanism can push the wet wipes into the packaging bag;

[0013] A sealing mechanism, which is used to seal the packaging bag, and the sealing mechanism is arranged on the right side of the pushing mechanism. The sealing mechanism includes an upper pressing component and a lower pressing component for sealing the packaging bag. Reinforcing crossbeams are fixedly connected above the upper pressing component and below the lower pressing component, and tightening bolts for pressing the middle position of the upper pressing component or the lower pressing component are also arranged on the reinforcing crossbeams;

[0014] A bag-supporting mechanism, which is used to expand the packaging bag, and the bag-supporting mechanism is arranged above the sealing mechanism;

[0015] A packaging bag feeding mechanism, which is used to supply the packaging bags.

[0016] By adopting the above technical solutions, the problem of poor sealing can be avoided. During the test, since the wet wipe line is changed from a two-row to a three-row one, the lengths of the upper pressing component and the lower pressing component increase. When sealing, the packaging bag in the middle position is prone to the situation that the packaging bag is not completely sealed. Although the unsealed length is very short (generally only a few tenths of a millimeter), it still affects the packaging quality.

[0017] We found that one of the reasons for the above problems is that the lengths of the upper pressing component and the lower pressing component are too long, resulting in sufficient supporting force at both ends of the upper pressing component or the lower pressing component, while the supporting force in the middle is insufficient. The present invention tightens the middle position of the upper pressing component or the lower pressing component through the tightening bolts, avoids the deformation of the middle position of the upper pressing component or the lower pressing component when the packaging bag is sealed, ensures that the forces at each position are basically the same after the upper pressing component and the lower pressing component are fitted together, and avoids the problem of poor sealing of the packaging bag caused by inconsistent forces.

[0018] As a further improvement, the thickness of the reinforcing crossbeam is not less than 40 mm.

[0019] By adopting the above technical solution, the operational stability of the upper pressing assembly and the lower pressing assembly is ensured, and the local loose fitting of the upper pressing assembly and the lower pressing assembly is greatly reduced or avoided.

[0020] As a further improvement, heating components are fixedly installed in the upper pressing assembly and the lower pressing assembly, and at least two heating components are arranged in the upper pressing assembly or the lower pressing assembly.

[0021] By adopting the above technical solution, the sealing is not tight due to heat problems. In the present invention, the number of wet wipes lines is changed from two to three, and the structure of the bag taking mechanism is improved, so the feeding speed is faster.

[0022] Two heating components can distribute heat more evenly, covering a wider sealing area and reducing heat blank spots. Even if each heating tube has a certain temperature difference, the heat of the two heating tubes complements each other, which can make the packaging bag more evenly heated as a whole, thereby improving the sealing effect. The total heat capacity of the two heating tubes is increased, which can provide more sufficient heat. When sealing plastic packaging bags, even if there is a continuous sealing operation, there is enough heat to fully melt the plastic and form a good seal. Moreover, the two heating tubes working at the same time can reach and maintain the appropriate sealing temperature in a shorter time, reducing the situation where the sealing is not tight due to insufficient heat or temperature fluctuations.

[0023] As a further improvement, the power of the heating component is not less than 500W.

[0024] By adopting the above technical solution, it is ensured that there is sufficient heat to seal the packaging bag.

[0025] As a further improvement, the material lifting mechanism includes a load-bearing plate and a lifting cylinder arranged under the load-bearing plate for driving the load-bearing plate to rise and fall, a wet wipe positioning cylinder is installed on the load-bearing plate, and the wet wipe positioning cylinder is connected to a wet wipe positioning plate for positioning the wet wipes in the front and rear directions;

[0026] A wet wipes limiting plate for limiting the right side of the wet wipes is also fixedly mounted on the external frame.

[0027] By adopting the above technical solution, the position of the stacked wet wipes can be accurately adjusted to ensure that the wet wipes can be accurately pushed into the packaging bag.

[0028] As a further improvement, the bag taking mechanism includes a mounting plate and a driving structure for driving the mounting plate to rotate, three bag supporting structures are respectively provided on the four sides of the mounting plate, and the mounting plate is also provided with an avoidance hole for cooperating with the pushing mechanism.

[0029] By adopting the above technical solution, the packaging efficiency can be greatly improved. In the prior art, the packaging bags are taken in a way of pairwise cooperation, that is, there are two groups of bag-supporting structures, two in each group (corresponding to double-line wet wipes). The two groups alternate up and down. When the lower bag-supporting structure pushes the wet wipes into the packaging bag, the bag-supporting mechanism puts the packaging bag on the upper bag-supporting structure. This results in low packaging efficiency, too long movement trajectory of the bag-supporting mechanism, and large amplitude of each swinging action, which is easily affected by inertia factors and affects positioning.

[0030] In the present invention, there are three in each group of bag-supporting structures, and the rotation feeding method is adopted. Each time, it only needs to rotate 90°. The action of rotating and changing materials takes short time and is accurate. Thus, the feeding speed of the bag-taking mechanism is greatly improved, enabling the production to run at a faster speed and greatly improving the packaging efficiency.

[0031] As a further improvement, a packaging bag positioning structure for positioning the mounting plate is further provided above the rotation driving structure.

[0032] As a further improvement, the packaging bag positioning structure includes a packaging bag positioning cylinder installed above the rotation driving structure. The packaging bag positioning cylinder is connected with a packaging bag positioning plate, and a positioning pin is fixedly installed on the packaging bag positioning plate. A positioning hole matched with the positioning pin is opened on the mounting plate.

[0033] By adopting the above technical solution, it is ensured that the packaging bag is in the same position each time, improving the packaging accuracy and ensuring the qualified product rate.

[0034] As a further improvement, the sealing mechanism further includes a waste material cutting mechanism for cutting the redundant waste material of the packaging bag.

[0035] By adopting the above technical solution, the redundant plastic is removed, making the packaging bag delicate and beautiful.

[0036] As a further improvement, a discharging mechanism for transporting the finished wet wipes is further provided on the right side of the sealing mechanism.

[0037] By adopting the above technical solution, the packaged wet wipes are discharged and transported to the set position.

[0038] The beneficial effects of the above technical solutions of the present invention are as follows:

[0039] 1. The present invention solves the packaging problems existing in the three-row production line by adjusting the thickness of the reinforcing cross beam, tightening the middle position of the upper pressing and combining assembly or the lower pressing and combining assembly, and the heat source, avoiding the situation that the packaging bags in the middle position are not completely sealed.

[0040] 2. Greatly improve the production efficiency of wet wipes. There are many factors that can affect whether the production efficiency of wet wipes can be improved. If only the efficiency of the wet wipe processing part is increased, but the packaging part cannot achieve a matching efficiency, it will also lead to the inability to improve or only a small improvement in the production efficiency of wet wipes.

[0041] The present invention greatly improves the production efficiency of the wet wipe production line through four aspects.

[0042] (1) The wet wipe packaging part is adjusted to three-line packaging corresponding to the wet wipe processing part;

[0043] (2) Adopt the method of rotary feeding. Each time, it only needs to rotate 90°. The operation time of the rotary material change is short and accurate, thus greatly improving the feeding speed of the bag-taking mechanism, enabling the production to run at a faster speed, and greatly improving the packaging efficiency.

[0044] (3) After the feeding speed is increased, the sealing also needs to be accelerated. The present invention supplies sufficient heat to ensure that after the equipment speed is increased, the sealing mechanism can still reach and maintain an appropriate sealing temperature in a short time.

[0045] (4) Strengthen components such as motors and roller shafts to improve the stability of such components. When the packaging system runs at high speed, problems such as component loosening or vibration will not occur, ensuring the stable operation of the production line. Description of the Drawings

[0053] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present invention.

[0054] Currently, in order to further increase the production output of wet wipes, our company subsequently started the research and development of a three-row synchronous automated production line. However, after changing from a two-row production line to a three-row production line, many problems have emerged.

[0055] Such as the problem of packaging bag sealing, etc.

[0056] Regarding the above problems, while solving the sealing problem, the present invention also improves the operating speed of the equipment and further improves the production efficiency.

[0057] For the sealing problem, since the two-row non-woven fabric is changed to a three-row non-woven fabric, the lengths of the upper pressing and combining component and the lower pressing and combining component increase. When sealing, the packaging bags in the middle position are prone to the situation that the packaging bags are not completely sealed, affecting the packaging quality.

[0058] The present invention increases the thickness of the reinforcing cross beam to reduce the deformation of the upper pressing and combining component or the lower pressing and combining component. At the same time, the middle position of the upper pressing and combining component or the lower pressing and combining component is tightened by the tightening bolts to further prevent the deformation of the middle position of the upper pressing and combining component or the lower pressing and combining component when sealing the packaging bag. Preferably, the two heating components can have a more uniform heat distribution, so as to cover a wider sealing area and reduce heat blank spots. Even when encountering continuous sealing operations, there is enough heat to fully melt the plastic and form a good seal.

[0059] The equipment speed is increased. By improving the bag-taking mechanism, sealing mechanism, and strengthening the motor and roller shafts, etc., the running speed of the equipment is increased, thereby improving production efficiency. The bag-taking mechanism adopts a rotary feeding method. Each time it only needs to rotate 90°, and the action of rotating and changing materials takes a short time and is accurate. Thus, the feeding speed of the bag-taking mechanism is greatly improved, enabling production to run at a faster speed and greatly improving the packaging efficiency. The improvement of the sealing device enables it to stably seal the packaging bags under the conditions of high speed and continuous operation. The strengthening of components such as the motor and roller shafts can ensure that the packaging production line will not have problems such as loose or vibrating parts during high-speed operation, guaranteeing the stable operation of the production line.

[0060] After introducing the basic principle of the present invention, the various non-limiting embodiments of the present invention will be specifically introduced below. The number of any element in the drawings is for illustration rather than limitation, and any naming is only for distinction and does not have any limiting meaning.

[0061] Next, with reference to several representative embodiments of the present invention, the principle and spirit of the present invention will be elaborated in detail.

[0062] Embodiment 1 of the wet wipe three-row synchronous automatic packaging system provided by the present invention:

[0063] As Figures 1 - 4 shown, the wet wipe three-row synchronous automatic packaging system includes a feeding and conveying mechanism 100 for conveying the stacked unpacked wet wipes, a lifting mechanism 200 for lifting the wet wipes, a pushing mechanism 300 for pushing the wet wipes into the packaging bags, a bag-taking mechanism 400 for taking the packaging bags and keeping the packaging bags in an open state, a sealing mechanism 500 for sealing the packaging bags, a bag-stretching mechanism 600 for stretching the packaging bags, a packaging bag loading mechanism 700 for supplying the packaging bags, and a discharging mechanism 800 for transporting the wet wipe finished products. It is defined that the moving direction of the wet wipes is to the right.

[0064] As Figure 2 shown, the lifting mechanism 200 is arranged at the end of the feeding and conveying mechanism 100; the lifting mechanism 200 includes a load-bearing plate 240 and a lifting cylinder arranged below the load-bearing plate 240 for driving the load-bearing plate 240 to lift and lower. A wet wipe positioning cylinder 230 is installed on the load-bearing plate 240, and the wet wipe positioning cylinder 230 is connected with a wet wipe positioning plate 220 for positioning the wet wipes in the front-back direction; the wet wipe positioning plate 220 is also provided with a fixed vertical plate. When the stacked wet wipes are conveyed between the wet wipe positioning plate 220 and the vertical plate, the wet wipe positioning cylinder 230 drives the wet wipe positioning plate 220 to move to position the wet wipes in the front-back direction.

[0065] A wet wipe limiting plate 210 for limiting the right side of the wet wipe is also fixedly installed on the external frame. The wet wipe limiting plate 210 is arranged on the external frame to prevent the wet wipe limiting plate 210 from rising with the load-bearing plate 240.

[0066] The pushing mechanism 300 includes a push rod that can slide in the left-right direction. In this embodiment, a pushing air cylinder is used to push the push rod to move. The pushing mechanism 300 is arranged above the feeding conveying mechanism 100;

[0067] As Figure 3 shown, the bag taking mechanism 400 is used to take the packaging bag and keep the packaging bag in an open state so that the pushing mechanism 300 can push the wet wipes into the packaging bag;

[0068] The bag taking mechanism 400 includes a mounting plate 420 and a rotation driving structure 410 for driving the mounting plate 420 to rotate. The rotation driving structure 410 uses a servo motor and is decelerated by a reducer. In this embodiment, the mounting plate 420 is square and the four corners are rounded. In other embodiments, a circular mounting plate 420 can also be used. Three bag supporting structures 430 are arranged on each of the four sides of the mounting plate 420. The mounting plate 420 is also provided with an avoidance hole for cooperating with the pushing mechanism 300.

[0069] Each group of bag supporting structures 430 has three, and adopts the method of rotary feeding. Each time it only needs to rotate 90°. The action of rotating and changing materials takes a short time and is accurate, thus greatly improving the feeding speed of the bag taking mechanism 400, enabling the production to run at a faster speed, and greatly improving the packaging efficiency.

[0070] In this embodiment, a packaging bag positioning structure 440 for positioning the mounting plate 420 is also arranged above the rotation driving structure 410. The packaging bag positioning structure 440 includes a packaging bag positioning air cylinder 441 installed above the rotation driving structure 410. The packaging bag positioning air cylinder 441 is connected with a packaging bag positioning plate 442. A positioning pin 443 is fixedly installed on the packaging bag positioning plate 442. A positioning hole cooperating with the positioning pin 443 is opened on the mounting plate 420. The front end of the positioning pin 443 is frustum-shaped, which can play a certain guiding role to ensure the accurate cooperation between the positioning pin 443 and the positioning hole.

[0071] As Figure 4As shown in the figure, the sealing mechanism 500 is arranged on the right side of the material pushing mechanism 300. The sealing mechanism 500 includes an upper pressing component 520 and a lower pressing component 530 for sealing the packaging bag. Reinforcing crossbeams 540 are fixedly connected above the upper pressing component 520 and below the lower pressing component 530. The thickness of the reinforcing crossbeam 540 is not less than 40 mm. A tightening bolt (not marked in the figure) for tightly pressing the middle position of the upper pressing component 520 or the lower pressing component 530 is also provided on the reinforcing crossbeam 540 to ensure the stable operation of the upper pressing component 520 and the lower pressing component 530, and greatly reduce or avoid the situation that the local parts of the upper pressing component 520 and the lower pressing component 530 are not tightly attached.

[0072] Heating components are fixedly installed in both the upper pressing component 520 and the lower pressing component 530. There are at least two heating components in the upper pressing component 520 or the lower pressing component 530. The power of each heating component is not less than 500 W to ensure sufficient heat supply to seal the packaging bag.

[0073] Two heating components can make the heat distribution more uniform, cover a wider sealing area, and reduce heat blank spots. Even if there are certain temperature differences in each heating tube itself, due to the heat complementarity between the two heating tubes, the packaging bag can be heated more evenly as a whole, thus improving the sealing effect. The total heat capacity of the two heating tubes increases, providing more sufficient heat. When sealing a plastic packaging bag, even in the case of continuous sealing operations, there is enough heat to fully melt the plastic and form a good seal. Moreover, the two heating tubes working simultaneously can reach and maintain the appropriate sealing temperature in a shorter time, reducing the situation of loose seals caused by insufficient heat or temperature fluctuations.

[0074] The sealing mechanism 500 further includes a waste material cutting mechanism 510 for cutting the excess waste material of the packaging bag to remove the excess plastic and make the packaging bag delicate and beautiful.

[0075] The bag supporting mechanism 600 is used to expand the packaging bag and is arranged above the sealing mechanism 500. The bag supporting mechanism 600 includes four parts. One is the cutting structure for disconnecting the strip-shaped packaging bag. The second is the negative pressure adsorption part. There are two negative pressure adsorption structures, which respectively adsorb the upper and lower surfaces of the packaging bag. The third is the lifting part, which expands the packaging bag by lifting the negative pressure adsorption structure located above. The fourth is the horizontal movement part, which drives the entire bag supporting mechanism 600 to move towards the bag supporting structure 430 and sleuth the packaging bag on the bag supporting structure 430. The bag supporting mechanism 600 is a prior art and is not improved in this embodiment. Only the quantity is adjusted, and its detailed structure will not be elaborated here.

[0076] The packaging bag feeding mechanism 700 and the discharging mechanism 800 are both prior arts and will not be elaborated here either.

[0077] The operation process of the device is as follows:

[0078] The stacked wet wipes pass through the feeding and conveying mechanism 100 and are conveyed to the lifting mechanism 200. The wet wipe limiting plate 210 can limit the position of the wet wipes and make them stop moving. The wet wipe positioning cylinder 230 drives the wet wipe positioning plate 220 to move to position the wet wipes in the front and back directions.

[0079] After positioning, the lifting mechanism 200 lifts the wet wipes, and the pushing mechanism 300 pushes the wet wipes into the packaging bag on the right; at the same time, the bag supporting mechanism 600 sets the packaging bag on the bag supporting structure 430;

[0080] When sealing, the upper pressing component 520 and the lower pressing component 530 squeeze the packaging bag to complete the sealing, and the surplus material cutting mechanism 510 cuts the excess packaging bag; during the sealing operation, the rotation driving structure 410 drives the mounting plate 420 to rotate 90° and performs a positioning operation to prepare for the next packaging.

[0081] After that, the device repeats the above actions.

[0082] Although this specification has shown and described multiple embodiments of the present invention, it is obvious to those skilled in the art that such embodiments are provided by way of example only. Those skilled in the art will think of many changes, alterations, and alternative ways without departing from the spirit and idea of the present invention. It should be understood that various alternative solutions of the embodiments of the present invention described herein can be adopted in the process of practicing the present invention. The appended claims are intended to define the protection scope of the present invention and thus cover the module compositions, equivalents, or alternative solutions within the protection scope of these claims.
