Description

Technical Field

[0001] The present invention relates to the technical field of non-woven fabric composite molding, and specifically to a composite layer non-woven fabric molding and processing device. Background Art

[0002] The composite layer non-woven fabric molding and processing device uses a method of roller pressing for molding, pressing the semi-solid film and the non-woven fabric together, and finally forming. This molding method has the advantages of simple process and high efficiency, and is suitable for large-scale industrial production.

[0003] However, there are still some problems with the existing composite layer non-woven fabric molding and processing devices:

[0004] First, before feeding, the film needs to be cooled to a semi-solid state to ensure its effective combination with the non-woven fabric during the subsequent pressing process. Currently, the existing technology generally uses a method of circulating the cooling medium to cool the film. Although this cooling method can achieve the cooling goal of the film to a certain extent, during the circulation process, the cooling medium flows from one end to the other end, and during this process, the medium continuously exchanges heat with the film, resulting in a gradual increase in its temperature. When the cooling medium circulates to the terminal, its temperature is already relatively high. Therefore, when cooling the film at the terminal, the effect will be greatly reduced, which causes inconsistent cooling effects of the film at the starting end and the terminal.

[0005] From the perspective of product quality, the film with insufficient cooling cannot be tightly combined with the non-woven fabric during pressing, resulting in quality problems such as delamination and blistering of the product. While the film with excessive cooling becomes too rigid and is difficult to form a good composite effect with the non-woven fabric, which will also affect the final quality of the product. From the perspective of production efficiency, due to the different cooling effects of the film at the starting end and the terminal, during the pressing process, it is necessary to continuously adjust parameters such as the pressure and temperature of the roller to ensure the forming quality of the product. This not only increases the complexity of production operations, but also reduces production efficiency and increases production costs.

[0006] Second, with the continuous feeding of the semi-solid film, its overall thickness gradually decreases. This change causes the subsequent semi-solid film to exchange heat with the air for a longer time due to the smaller radius. Specifically, due to the smaller radius, the contact area between the subsequent semi-solid film and the air relatively increases, and the heat exchange time lengthens. This makes the outer film have a relatively higher temperature during the heat exchange process, while the inner film has a lower temperature due to sufficient cooling. This temperature difference is extremely likely to cause thermal stress in the film during the pressing process, thereby affecting the structural integrity and mechanical properties of the composite layer non-woven fabric. At the same time, the uneven temperature will also affect the bonding effect between the non-woven fabric and the film, resulting in a decrease in the quality of the composite layer non-woven fabric;

[0007] In addition, the long-term heat exchange between the semi-solid diaphragm and air will also cause the surface of the diaphragm to harden or form a crust, reducing its plasticity and adhesiveness. This will not only affect the pressing effect between the diaphragm and the non-woven fabric, but also increase the energy consumption and waste rate during the production process, because the hardened diaphragm requires higher temperature and pressure to effectively bond with the non-woven fabric, undoubtedly increasing the production cost and time.

[0008] For this reason, the present invention proposes a composite layer non-woven fabric forming and processing device. Summary of the Invention

[0016] Preferably, a variable pitch assembly is provided on the outer side of the cooling roller, and the variable pitch assembly includes a double-tooth gear, which is rotatably connected to the outer wall of the base, and the lower part of the double-tooth gear is meshedly connected with a multiple-seeding gear rotatably connected to the outer wall of the base, and the outer surface of the sliding frame is fixedly connected with a sliding gear rod meshing with the multiple-seeding gear, the top of the base is rotatably connected with a mating roller, the top of the base is fixedly connected with an extension spring, and the top of the extension spring is fixedly connected with a resisting circular plate.

[0019] Preferably, the feeding module includes a feeding motor, a feeding roller, a first belt, and a second belt.

[0020] Preferably, the tension roller group includes four tension rollers.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] 1. By the relative movement of two extrusion circular shells, the distribution of the cooling medium in the cooling roller is changed. The heat exchange component creates a separate cooling atmosphere for the left end, middle, and right end of the cooling roller, thus ensuring that the temperature of the diaphragm is more uniform throughout the cooling process, avoiding the problem of inconsistent cooling effects at the starting end and the terminal end. The consistency of the cooling effect directly improves the product quality of the composite non-woven fabric. Since the diaphragm reaches an ideal semi-solid state before pressing, it combines more tightly with the non-woven fabric, effectively avoiding quality problems such as delamination and blistering. At the same time, the diaphragm with appropriate cooling is also more likely to form a good composite effect with the non-woven fabric, further improving the overall quality of the product;

[0023] Compared with the prior art, in the prior art, the temperature of the cooling medium gradually increases during the circulation process, resulting in inconsistent cooling effects of the diaphragms at the starting end and the terminal end. The heat exchange component ensures the temperature uniformity of the entire diaphragm during the cooling process by changing the distribution of the cooling medium, effectively solving this problem;

[0024] Among them: By controlling the sliding valve with the abutting circular block to no longer block the through port, the cooling medium is more inclined to circulate from the middle of the through port rather than from the outside of the extrusion circular shell. Therefore, the residence time of the cooling medium in the middle of the cooling roller can be prolonged, effectively preventing the problem of uneven cooling caused by the small heat dissipation area in the middle;

[0025] Among them: When the extrusion circular shell moves, the extrusion circular shell combines with the convex ring, resulting in a smaller medium passage, increasing the flow rate of the cooling medium at the initial end of the cooling roller, so that the initial end will not exchange heat with the cooling medium too much. Under the guiding action of the extrusion circular shell, the flow rate will further increase and tilt towards the middle, and finally, under the guiding action of the other extrusion circular shell, separate cooling of the terminal end of the cooling roller is achieved;

[0026] Among them: Under the limitation of the elliptical plate and the rotating rod, different movements of the extrusion circular shell will make the cooling medium focus on different parts of the cooling roller. With the cooperation of the elliptical plate and the rotating rod, the two extrusion circular shells move in opposite directions at the same frequency, which not only helps to solve the problem of inconsistent cooling effects of the diaphragms at the starting end and the terminal end, but also further improves the product quality of the composite non-woven fabric and ensures the smooth progress of production.

[0027] 2. The rotation of the double-tooth gear drives the synchronous rotation of the multiple-planting gear, and then the rotation of the multiple-planting gear drives the movement of the sliding tooth rod, reducing the distance between the cooling roller and the feeding module. The variable-distance component effectively reduces the problem that the semi-solid diaphragm exchanges heat with air for a long time due to the decreasing radius during the feeding process. Specifically, due to the reduction of the distance between the cooling roller and the feeding module, the semi-solid diaphragm can enter the cooling and pressing areas faster, reducing the contact time and heat exchange time with air, thereby reducing the relative temperature of the outer diaphragm and making the overall temperature of the diaphragm more uniform. This not only helps to eliminate the thermal stress problem caused by temperature differences, improve the structural integrity and mechanical properties of the composite-layer non-woven fabric, but also improves the adhesion effect between the non-woven fabric and the diaphragm, enhancing the overall quality of the composite-layer non-woven fabric;

[0028] Compared with the prior art, in the prior art, the semi-solid diaphragm often exchanges heat with air for a long time due to the decreasing radius during the feeding process, resulting in the hardening or skinning of the diaphragm surface, reducing its plasticity and adhesiveness. This not only affects the pressing effect between the diaphragm and the non-woven fabric, but also increases the energy consumption and waste rate during the production process. The variable-distance component avoids the problem of hardening or skinning of the diaphragm surface by effectively reducing the heat exchange time between the diaphragm and air, maintaining the good plasticity and adhesiveness of the diaphragm;

[0029] Among them: the deceleration effect is achieved through the meshing of the double-tooth gear and the multiple-planting gear. The double-tooth gear is connected to the pressing motor through Belt 2, without the need for an additional drive source. This not only simplifies the system structure, but also reduces the energy consumption and production cost. In addition, the realization of the deceleration effect enables the distance between the cooling roller and the feeding module to be controlled more precisely, further improving the production quality and efficiency of the composite-layer non-woven fabric. At the same time, compared with other deceleration mechanisms, the combination of the double-tooth gear and the multiple-planting gear has a lower cost;

[0030] Among them: the intermittent movement of the sliding tooth rod is realized by the rotation of the long tooth, which enables the semi-solid diaphragm to enter the cooling and pressing areas step by step, making it more conducive to controlling the temperature and heat exchange time of the diaphragm. Secondly, the arc tooth fits the surface of the double-tooth gear. This design can effectively prevent vibration during the movement process, ensuring that the diaphragm on the cooling roller does not shift during the movement. This not only improves the accuracy and stability of the product, but also effectively reduces the waste rate. BRIEF DESCRIPTION OF THE DRAWINGS

[0055] The output end of the water pump 21 can be interconnected with an external water tank.

[0056] The extrusion circular shell 24 close to the water pump 21 is denoted as the right extrusion circular shell 24, and the extrusion circular shell 24 far from the water pump 21 is denoted as the left extrusion circular shell 24.

[0057] The working principle of implementing the present invention in combination with the above is as follows:

[0058] The following is the initial state: The extension spring 35 is in a compressed state, the reciprocating rod 212 is located in the middle of the insertion rod 214, the sliding frame 213 is located on the side of the base 11 away from the pressing module 12, the fixed double-layer columns 25 are all located in the middle of the stroke, the tension spring 29 is not compressed, and the sliding valve 28 blocks the through port 27.

[0059] The following are the specific operating steps of the work:

[0060] Among them, the installation of the non-woven fabric and the diaphragm:

[0061] As Figure 1 and Figure 2 shown, the operator removes the output pipe from the surface of the feeding module 15 farthest from the cooling roller 14, and snaps the molten diaphragm core onto the outer surface of the cooling roller 14. At the same time, the operator also needs to snap the core of the non-woven fabric onto the outer surface of the feeding roller, and then the operator resets the output pipe.

[0062] Immediately afterwards, the operator alternately bypasses one end of the non-woven fabric and the diaphragm from the surface of the tension roller, ensuring that they are vertically arranged and closely attached at the lower tension roller. In addition, the operator also needs to pass the attached composite non-woven fabric through between the two pressure rollers and alternately bypass the horizontally arranged tension rollers again.

[0063] Finally, the operator pastes one end of the composite non-woven fabric on the surface of the winding roller, and electrically controls the pressing module 12, the winding module 13, the feeding module 15 and the water pump 21 to start through an external controller, and starts the production process.

[0064] Among them, the forming and processing of the composite non-woven fabric:

[0065] As Figure 1 and Figure 2 shown, when the winding module 13 starts, the tension motor starts to work and drives the winding roller to rotate, so that the non-woven fabric and the diaphragm are subjected to a pulling force and start to move forward. At the same time, the feeding motor also starts, and through the belt drive mechanism, the cooling roller 14 and the feeding roller can rotate synchronously. Therefore, the non-woven fabric on the feeding roller and the diaphragm on the cooling roller 14 are continuously conveyed forward.

[0066] During the conveying process, the non-woven fabric and the membrane will pass through the pressing roller, which relies on its own force to press the non-woven fabric and the membrane tightly together. Since the cooling roller 14 is away from the winding module 13 at this time, the membrane spends a relatively long time in the moving process, and the heat dissipation area of ​​the membrane outside the cooling roller 14 is large, so the membrane involved in the pressing is already in a semi-solid state.

[0067] After being pressed by the pressure roller, the composite layer non-woven fabric is neatly rolled onto the winding roller. As the production process continues, more and more composite layer non-woven fabrics are placed on the winding roller, eventually forming a complete roll.

[0068] Among them, the uniform cooling of the diaphragm:

[0069] like Figures 2 to 8 As shown, in the above process, the water pump 21 has been started, and then the water pump 21 draws water from the external water pool and injects the cooling medium into the cooling roller 14, starting the circulation of the cooling medium. At the same time, the feeding motor drives the cooling roller 14 synchronously through the belt drive. Since the extrusion shell 24 slides inside the cooling roller 14, the extrusion shell 24 will also rotate synchronously with the cooling roller 14.

[0070] At this time, the rotation of the right extrusion shell 24 will cause the reciprocating rod 212 to rotate synchronously through the fixed double-layer column 25. Since the reciprocating rod 212 is restricted by the extrusion shell 24, the bidirectional threaded groove on its surface will interfere with the inserted rod 214 during the rotation. This interference makes the reciprocating rod 212 rotate while sliding back and forth. When the reciprocating rod 212 slides toward the side away from the cooling roller 14, it will drive the right extrusion shell 24 to slide synchronously in the direction away from the center of the cooling roller 14. At this time, the right extrusion shell 24 will cause the left extrusion shell 24 to also move synchronously away from the center of the cooling roller 14 through the transmission action of the rotating rod 23 and the elliptical plate 22.

[0071] In this process, the fixed double-layer column 25 on the right side will come into contact with the convex ring 211, causing the passage of the medium through the fixed double-layer column 25 to become smaller. As the passage becomes smaller, the cross-sectional area through which the medium flows decreases. According to the flow conservation principle, the flow velocity will increase, that is, the medium will accelerate to flow through the fixed double-layer column 25. At the same time, the space between the two extruded circular shells 24 will increase. While the extruded circular shell 24 on the left side is moving, the mating round rod 210 will come into contact with the abutting round block 26. The design of the smooth surface enables the abutting round block 26 to generate a downward component force when it contacts the mating round rod 210, thereby pushing the mating round rod 210 to move downward, thereby driving the sliding valve 28 to move toward the bottom and compressing the tension spring 29.

[0072] At this time, the sliding valve 28 no longer blocks the through-port 27, allowing the cooling medium to pass through this path. However, due to the mutual approach of the two extrusion circular shells 24, the gap between them becomes relatively narrow, which to a certain extent blocks the direct passage of the cooling medium. Nevertheless, the cooling medium will still accelerate through the starting end of the cooling roller 14 and reach the middle region between the two extrusion circular shells 24.

[0073] In this case, although the through-port 27 is already open, due to its small cross-sectional area, the amount of cooling medium that can pass through is relatively limited. Therefore, most of the cooling medium will tend to find a larger outlet to flow out after reaching the middle region. Since the through-port 27 is the only open outlet at this time and the flow capacity of the narrow gap between the extrusion circular shells 24 is limited, the remaining cooling medium is more inclined to be output from the through-port 27 rather than flowing out from the edge gaps of the extrusion circular shells 24. As a result, the cooling medium has more time for heat exchange, supplementing the cooling in the middle and making the cooling efficiency in the middle equivalent to that at the starting end.

[0074] As the reciprocating rod 212 continuously moves, under the contact action of the sliding frame 213, it will pull the right extrusion circular shell 24 to slide towards the side close to the center of the cooling roller 14. At this time, the fixed double-layer column 25 no longer fits the convex ring 211, but under the action of the elliptical plate 22 and the rotating rod 23, the space between the two extrusion circular shells 24 will decrease. During this process, due to the change in the passage and the continuous rotation of the cooling roller 14, the flow of the cooling medium will change. Specifically, when the space between the two extrusion circular shells 24 decreases, the flow rate of the medium will relatively slow down. And due to the rotation of the cooling roller 14 and the guiding effect of the arc surface of the extrusion circular shell 24, the medium above will be subject to the dual action of gravity and guiding, tending to converge in the middle. At the same time, during the rotation of the cooling roller 14, the cooling roller 14 will cause the medium below to generate a centripetal force, so that the medium below also has a tendency to converge towards the center. As a result, the medium reduces the heat exchange opportunity with the middle, thus maximizing the cooling effect of the cooling medium. In addition, when the two extrusion circular shells 24 approach each other and compress the cooling medium between them, since the temperature of the medium in the middle is already higher than the initial state, this will lead to the formation of a temperature gradient.

[0075] Due to the output of the water pump 21, the cooling medium has an initial velocity, which will block the direct flow of the high-temperature medium and push it upwards to form a protective layer. During this process, the relatively high-temperature medium will flow back from the gap between the two extrusion circular shells 24 because the high-temperature medium tends to find a lower-temperature region for heat exchange when being compressed. Since the temperature gradient between the high-temperature medium and the cooling medium is small, this backflow phenomenon not only protects the cooling medium from excessive heat exchange with the inner wall of the cooling roller 14 but also limits the heat exchange between the high-temperature medium and the cooling medium itself.

[0076] When the left extrusion circular shell 24 moves and causes the mating circular rod 210 to reset under the elastic extension of the tension spring 29, the sliding valve 28 will block the through-port 27 again. At this time, the medium in the middle can only flow through the edge of the left extrusion circular shell 24. Since the space between the left extrusion circular shell 24 and the end of the cooling roller 14 increases, a negative suction force will be generated to guide the medium to flow from the edge.

[0077] Furthermore, the heat exchange efficiency of the medium at this time with the starting end and the middle is relatively low. And under the guidance of the left extrusion circular shell 24, the medium will move along the end of the cooling roller 14 and conduct separate heat exchange with the end, thus ensuring that the cooling roller 14 can uniformly cool the surface of the diaphragm, and maintaining a stable cooling effect even when the medium flow and heat exchange conditions change.

[0078] Among them, for the movement of the cooling roller 14:

[0079] As Figure 2 and Figure 4 shown, at the same time, the feeding motor rotates the driving double-toothed gear 31 through the second belt. The number of teeth on the surface of the double-toothed gear 31 is relatively small. Therefore, when it rotates and meshes with the lower multiple-planting gear 32, it will cause a deceleration and intermittent meshing effect. The circular arc teeth of the multiple-planting gear 32 are closely attached to the outer surface of the double-toothed gear 31, increasing the contact area between the two and improving the transmission stability, effectively preventing transmission errors or slippage caused by tooth gaps.

[0080] When the double-toothed gear 31 rotates, it drives the multiple-planting gear 32 to rotate in a decelerated manner. The long teeth of the multiple-planting gear 32 mesh with the sliding tooth bar 33 on the sliding frame 213. As the multiple-planting gear 32 rotates, the sliding tooth bar 33 is driven to move linearly. This movement is then transmitted to the sliding frame 213 and ultimately indirectly causes the cooling roller 14 to move towards the side close to the pressing module 12.

[0081] The tooth profile design of the multiple-planting gear 32 makes its driving of the sliding tooth bar 33 periodic. Because it helps to prevent the diaphragm on the cooling roller 14 from running off during movement. Through periodic adjustment and control, the diaphragm can maintain a stable movement trajectory, thus ensuring the accuracy of subsequent processing or treatment.

[0082] In addition, the periodic movement also helps to reduce the excessive contact between the diaphragm and the air. Since as the sliding frame 213 continuously moves, its distance from the pressing module 12 gradually decreases. Thus, on the premise of ensuring long-time heat exchange between the diaphragm outside the cooling roller 14 and the air, it also achieves the effect that the diaphragm inside the cooling roller 14 does not exchange heat with the air for too long.

[0083] Meanwhile, as the sliding carriage 213 moves, the belt on the surface of the cooling roller 14 will become slack due to the change in distance. When the belt becomes slack, the extension spring 35 drives the abutting circular plate 36 to elastically extend, and the movement of the abutting circular plate 36 generates a thrust force to push the belt upward, thereby effectively adjusting the tension of the belt.
