Description

Technical Field

[0001] This application relates to the field of thin film composite technology, and in particular to a three-in-one solvent-free laminating machine. Background Technology

[0002] A three-in-one solventless laminator is a device that laminates three layers of film into one layer. It mainly works by moving the three layers of film forward on a transfer roller, feeding adhesive through a metering roller on the laminator, and then coating the film with adhesive through a coating roller. Next, two of the films to be laminated are pressed together by a heated coating roller to form a two-layer composite film. The above operation is repeated to press the film together with another layer of film to form a three-layer composite film.

[0003] In the process of conveying adhesives and pressing films, the metering roller needs to be heated in order to adjust the adhesive viscosity, improve coating accuracy and reduce air bubbles. The coating roller needs to be heated in order to enhance the flowability of adhesives and promote adhesive curing. Generally, the heating temperature is controlled between 50 and 60 degrees Celsius, depending on the composite requirements of different materials.

[0004] One heating method involves heating heat transfer oil and circulating it through the cavity inside the roller to heat the roller. In this method, there are input and output ends on both sides of the roller. Since the heat transfer oil is input from one end and flows to the output end at the other end, at the input end, most of the heat is absorbed. As the heat transfer oil moves forward, the temperature of the area where the heat transfer oil is located will gradually decrease, resulting in a temperature gradient along the roller axis. Furthermore, the heat transfer oil far from the area to be heated on the roller is unlikely to come into direct contact with the inner wall of the roller during its movement. Most of the heat exchange is completed through heat transfer from the heat transfer oil that is in direct contact with the inner wall. However, this means that most of the heat transferred by the heat transfer oil per unit time is difficult to be directly absorbed by the roller.

[0005] The surface temperature of the roller varies in a gradient, resulting in uneven temperature distribution over a large area. This can easily lead to differences in the viscosity of the adhesive in different temperature zones, and the curing speed will also vary due to the temperature difference. This can cause the composite film to be too thick or too thin in some areas, which will also affect the physical properties of the composite film.

[0006] Therefore, ensuring the uniformity of roller heating is a problem that many manufacturers need to consider. Existing manufacturers generally add multiple guide plates of different shapes in the inner cavity of the roller. However, the design of the guide plates reduces the effective space in the inner cavity of the roller, reduces the effective heat transfer oil input per unit time, increases flow resistance, and the presence of irregularly shaped guide plates makes processing difficult, leading to increased processing costs. Furthermore, as the heat transfer oil continues to flow in the inner cavity of the roller, carbon deposits will gradually increase. The presence of guide plates will cause a large amount of carbon deposits to be trapped by the guide plates, further increasing the difficulty of cleaning. Summary of the Invention

[0007] This application proposes a three-in-one solventless laminating machine, which features a partition cylinder forming a forward and return chamber for heat exchange. High-temperature and low-temperature heat transfer oils exchange heat to ensure axial temperature uniformity. The high-temperature heat transfer oil directly contacts and mixes with the low-temperature heat transfer oil. The heat transfer oil is sprayed out through an inclined hole to form a liquid flow that acts as a guide plate. The forward liquid flow impacts the sprayed liquid flow to increase turbulence, and the inclined liquid flow guides the surrounding liquid flow to drive the cleaning component to rotate and clean. This invention solves the problems of axial temperature difference and ineffective heat loss in existing three-in-one solventless laminating machines where various rollers requiring heat transfer oil heating exist.

[0008] To achieve the above objectives, this application adopts the following technical solution: a three-in-one solventless laminating machine, comprising a laminating machine frame, a fixed metering roller, a rotating metering roller, a transfer roller, a coating pressure roller, and a coating roller arranged on the laminating machine frame, wherein the coating roller includes an outer contact unit and an inner heat exchange unit; the contact unit includes an end seat I disposed on one side of the laminating machine frame, an end seat II disposed on the other side of the laminating machine frame, and a roller disposed between the end seat I and the end seat II; the heat exchange unit includes a central roller disposed inside the contact unit, a sealed end disposed on one side of the central roller, and a roller disposed outside the central roller. A separator cylinder has a fixing ring on one side that is sleeved with a central roller. A reflux cavity is formed between the inner wall of the roller and the outer wall of the separator cylinder, and a forward cavity is formed between the inner wall of the separator cylinder and the central roller. There is a gap between the side of the separator cylinder near the end seat II and the same side of the end seat II, which is used to connect the forward cavity and the reflux cavity. An input hole is opened at the center of the sealed end and the central roller, and a circumferentially distributed distribution hole is opened on one side of the central roller, which is used to connect the input hole and the forward cavity. Multiple sets of circumferentially opened inclined holes are evenly distributed along the axial direction of the separator cylinder. A cleaning component is provided on the separator cylinder.

[0009] Preferably, one end of the end seat II is provided with a transmission gear.

[0010] Preferably, the end seat I has a closed groove on the side away from the roller, and the sealed end is fitted into the closed groove on the side closer to the center roller.

[0011] Preferably, a converging cavity is provided on the sealed end, and circumferentially distributed reflux holes are provided on the end seat I for connecting the converging cavity and the reflux cavity. A discharge pipe is provided on the sealed end to connect to the converging cavity.

[0012] Preferably, the inclined holes in a single circumferential opening are evenly distributed in the circumferential direction, and the inclined holes are inclined in the circumferential direction, with the inclination direction being the same as the rotation direction of the roller.

[0013] Preferably, the cleaning assembly includes an annular collar disposed on the central roller, uprights evenly distributed circumferentially on the outer wall of the collar, scraper rods I, II, and III disposed on the uprights from bottom to top, and a force-bearing plate evenly distributed axially between scraper rods II and III.

[0014] Preferably, a limiting groove is provided on the side of the center roller near the end seat II, and the collar is sleeved in the limiting groove.

[0015] Preferably, one side of scraper I is in contact with the inner wall of the separator cylinder, one side of scraper II is in contact with the outer wall of the separator cylinder, and one side of scraper III is in contact with the inner wall of the roller.

[0016] Preferably, the force-bearing plate is concave in the direction of the roller's rotation.

[0017] This application provides a three-in-one solventless laminating machine. By setting a separator cylinder inside the roller, a forward cavity is formed on the inner side of the separator cylinder and a return cavity on the outer side of the separator cylinder. This allows heat transfer oil to enter from one side of the forward cavity, continue forward to the other side of the forward cavity, and then hit the end seat II to turn and enter the return cavity. In the return cavity, it moves in the opposite direction, thus creating opposite flow directions in the forward cavity and the return cavity. This allows the heat transfer oil that has just entered the forward cavity to exchange heat with the heat transfer oil that is about to be discharged from the return cavity through the separator cylinder. The heat transfer oil that has traveled halfway in the forward cavity can exchange heat with the heat transfer oil that has traveled halfway in the return cavity. This allows the temperature of the heat transfer oil on both sides of the return cavity to be gradient heated through the heat transfer oil on both sides of the forward cavity, improving the temperature uniformity on both sides of the axial direction of the return cavity.

[0018] Meanwhile, by evenly distributing multiple sets of circumferentially inclined holes on the separator cylinder, a portion of the heat transfer oil in the forward cavity can be sprayed into the return cavity through the inclined holes. The temperature of the heat transfer oil is higher closer to the inlet of the forward cavity and lower closer to the outlet of the return cavity. At this time, the relatively high temperature heat transfer oil sprayed into the return cavity from the forward cavity will mix with the relatively low temperature heat transfer oil at the same axial position in the return cavity. Thus, under the premise of heat exchange through the separator cylinder, more direct heat transfer oil mixing will occur, thereby further ensuring the temperature uniformity of the roller in the axial direction.

[0019] Meanwhile, the heat transfer oil sprayed from the inclined hole will form a circumferential inclined obstructing liquid flow at the nozzle, while the axially advancing liquid flow in the return cavity will collide with this inclined obstructing liquid flow, causing the two liquid flows to diffuse and ripple due to the collision. This enhances the turbulent state of the heat transfer oil around the obstructing liquid flow, allowing the heat transfer oil in different areas to have the opportunity to directly contact the inner wall of the roller for direct heat exchange, thereby improving the heat exchange efficiency.

[0020] Meanwhile, because the obstructing liquid flow is tilted to one side in the circumferential direction, when the advancing liquid flow collides with the obstructing liquid flow, most of the liquid flow in the direction of advancement will be tilted and guided in the circumferential direction. This part of the liquid flow can impact the concave side of the nearby force plate, providing a circumferential thrust. This causes the force plate to drive the entire cleaning assembly to rotate slowly in the circumferential direction. As a result, the three scrapers scrape off the deposits in the circumferential direction on the inner wall of the roller and the inner and outer walls of the separator cylinder, respectively. The turbulent liquid flow will carry away the scraped deposits. Attached Figure Description

[0024] 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, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0025] Example 1 Please see Figure 1 A three-in-one solventless laminating machine includes a laminating machine frame 1. A fixed metering roller 2, a rotating metering roller 21, a transfer roller 22, a coating pressure roller 23, and a coating roller 24 are driven and sleeved on the laminating machine frame 1. The fixed metering roller 2 is close to the rotating metering roller 21, the transfer roller 22 is close to the rotating metering roller 21, the coating roller 24 is close to the transfer roller 22, and the coating pressure roller 23 is close to the coating roller 24.

[0026] The laminating machine frame 1 is also equipped with auxiliary devices found in existing three-in-one solventless laminating machines, such as adhesive input devices, drive motors, gearboxes, and recycling tanks for recovering adhesives.

[0027] The rollers that need to be heated in the laminating machine have the same structure as the coating roller 24, but different dimensions.

[0028] See Figures 2 to 4 The coating roller 24 includes an outer contact unit and an inner heat exchange unit, which allows the heat exchange unit to heat the contact unit uniformly, so that the part of the contact unit that contacts the film provides uniform heat supply to the film.

[0029] The contact unit includes an end seat I3 movably sleeved on one side of the laminating machine frame 1, an end seat II 31 movably sleeved on the other side of the laminating machine frame 1, and a roller 32 fixedly sleeved between the end seat I3 and the end seat II 31.

[0030] One end of the end seat II 31 is fixedly connected to a transmission gear 34, which enables the transmission gear 34 to be connected to an existing transmission device, thereby driving the entire contact unit to rotate, causing a portion of the roller 32 to rotate and contact the film.

[0031] See Figures 2 to 8 The heat exchange unit includes a central roller 41 movably sleeved inside the contact unit, a sealed end 4 fixedly connected to one side of the central roller 41, and a partition cylinder 5 fixedly sleeved outside the central roller 41.

[0032] The end seat I3 is movably sleeved on the outside of the center roller 41, and a closing groove 35 is provided on the side of the end seat I3 away from the roller 32. The side of the sealed end 4 close to the center roller 41 is movably sleeved in the closing groove 35, so that when the end seat I3 rotates, it can avoid leakage of heat transfer oil by contacting the sealed end 4.

[0033] The end of the center roller 41 away from the sealed end 4 moves through the center of the end seat II 31 and the transmission gear 34 to the outside, so that the entire heat exchange unit is centered on the contact unit.

[0034] A sealing ring is provided at the contact position between the closed groove 35 and the sealed end 4, and a sealing ring is provided at the contact position between the center roller 41 and the end seat II 31.

[0035] See Figure 3 , Figures 6 to 8 A fixing ring 51 is fixedly sleeved at one end of the separator cylinder 5 near the end seat I3. The inner side wall of the fixing ring 51 is fixedly sleeved with the outer side wall of the center roller 41, so that the separator cylinder 5 can form a cavity between the fixing ring 51 and the center roller 41.

[0036] The side of the fixing ring 51 near the sealed end 4 is fitted with the side of the end seat I3 away from the sealed end 4, and a sealing ring is provided at the fitting point, so that there is no additional gap between the fixing ring 51 and the end seat I3, thus preventing heat transfer oil from remaining in the additional gap.

[0037] See Figures 3 to 6 The sealed end 4 and the center roller 41 are provided with an input hole 42 that is connected. The center roller 41 is provided with a circumferentially distributed distribution hole 43 on the side near the fixed ring 51 that is connected to the input hole 42, so that the heated heat transfer oil can enter the input hole 42 and then enter the forward cavity through the distribution hole 43.

[0038] See Figure 3 , Figure 8 A reflux cavity is formed between the inner wall of roller 32 and the outer wall of separator 5, and a forward cavity is formed between the inner wall of separator 5 and center roller 41, so that the heat transfer oil in the forward cavity can heat the heat transfer oil in the reflux cavity through separator 5.

[0039] The distribution hole 43 is connected to the side of the forward cavity near the fixed ring 51, so that the heat transfer oil can first enter the side of the forward cavity near the fixed ring 51, and then flow to the side of the forward cavity near the end seat II 31. During this process, due to the continuous loss of energy, the heat of the heat transfer oil gradually decreases as the forward path increases.

[0040] See Figures 3 to 6 The end seat I3 is provided with circumferentially distributed return holes 33, which are connected to the side of the return cavity near the end seat I3.

[0041] An annular converging cavity 44 is provided on the sealed end 4. One side of the annular opening of the converging cavity 44 is connected to the side of the return hole 33 away from the return cavity. A discharge pipe 45 is fixedly connected to the sealed end 4 and is connected to the converging cavity 44, so that the heat transfer oil flowing back in the return cavity can enter the converging cavity 44 through the return hole 33 and then be discharged through the discharge pipe 45.

[0042] There is a gap between the side of the separator 5 near the end seat II 31 and the same side of the end seat II 31.

[0043] The inlet chamber and the return chamber are connected through the gap between the separator 5 and the end seat II 31, so that the heat transfer oil in the inlet chamber that reaches the end seat II 31 can hit the side of the end seat II 31 facing the separator 5, and then turn and enter the return chamber from the side of the return chamber near the end seat II 31. This causes the heat transfer oil to move continuously from the side of the return chamber near the end seat II 31 towards the return hole 33 after turning.

[0044] During this process, as energy is continuously lost, the heat of the heat transfer oil advancing in the reflux chamber gradually decreases. At this point, there is a temperature difference between the heat transfer oil in the reflux chamber and the heat transfer oil in the advancing chamber at the same point in the axial direction. At this time, the heat transfer oil in the advancing chamber exchanges heat with the heat transfer oil in the reflux chamber through the separator 5, so that the heat transfer oil in the reflux chamber is heated under heat exchange and forms a more uniform temperature distribution in the axial direction.

[0045] Specifically, in the forward chamber, the temperature of the heat transfer oil gradually decreases from the inlet to the outlet. The same applies to the return chamber. However, the temperature difference between the inlet and outlet points in the forward chamber is large, allowing the heat transfer oil in the return chamber to gain more heat to compensate for the temperature difference. Conversely, the temperature difference between the outlet and inlet points in the forward chamber is small, so the heat transfer oil in the return chamber only gains a small amount of heat for reheating. Under flow conditions, the temperature difference on both sides of the axial direction of the return chamber gradually tends to balance, thereby improving the uniformity of temperature distribution.

[0046] Example 2 Please see Figure 3 , Figures 7 to 8 Based on Embodiment 1, the separator cylinder 5 has multiple sets of circumferentially opened inclined holes 52 evenly distributed along its axial direction.

[0047] The inclined holes 52, which are opened in a single circumferential direction, are evenly distributed in the circumferential direction.

[0048] This allows a portion of the heat transfer oil in the forward cavity to be sprayed into the return cavity through the inclined hole 52. The temperature of the heat transfer oil in the forward cavity is higher closer to the inlet, while the temperature of the heat transfer oil in the return cavity is lower closer to the outlet. At this time, the relatively high temperature heat transfer oil sprayed into the return cavity from the forward cavity will mix with the relatively low temperature heat transfer oil at the same axial position in the return cavity. Thus, under the premise of heat exchange through the separator 5, more direct heat transfer oil mixing will occur, thereby further ensuring the temperature uniformity of the roller 32 in the axial direction.

[0049] The inclined hole 52 is circumferentially inclined, and the inclination direction is the same as the rotation direction of the roller 32.

[0050] The heat transfer oil ejected from the inclined hole 52 will form a circumferential inclined obstructing liquid flow at the nozzle (equivalent to an alternative guide plate). The axially advancing liquid flow in the return cavity will collide with this inclined obstructing liquid flow, causing the two liquid flows to diffuse and ripple due to the collision. This enhances the turbulent state of the heat transfer oil around the obstructing liquid flow, allowing the heat transfer oil in different areas to have the opportunity to directly contact the inner wall of the roller 32 for direct heat exchange, thereby improving the heat exchange efficiency.

[0051] The design that blocks the flow of liquid avoids the need for adding a large number of additional guide plates, reducing processing costs and also reducing problems such as excessive carbon buildup and difficulty in cleaning caused by physical guide plates.

[0052] It should be noted that the spacing of the inclined holes 52 in the axial and circumferential directions is designed according to the actual requirements such as the flow rate and temperature of the heat transfer oil, so that when a diffused liquid flow is formed, it can cover the entire area and ensure uniformity.

[0053] Meanwhile, since the tilting direction of the inclined hole 52 is the same as the rotation direction of the roller 32, the obstructing liquid flow ejected from the inclined hole 52 is mainly tilted in the rotation direction of the roller 32, and at this time, most of the diffused and agitated liquid flow also moves in this direction.

[0054] Example 3 Please see Figure 3 , Figures 7 to 9 Based on Example 2, a cleaning component is movably sleeved on the separator cylinder 5.

[0055] The cleaning assembly includes an annular collar 6 that is movably sleeved on the central roller 41, uprights 61 that are circumferentially distributed and fixedly connected to the outer wall of the collar 6, scraper rods I 62, II 63 and III 64 that are fixedly connected to the uprights 61 from bottom to top, and a force-bearing plate 65 that is axially distributed and fixedly connected between scraper rods II 63 and III 64.

[0056] The collar 6 is formed by two symmetrical half-rings fixed together by bolts, which makes the collar 6 easy to disassemble and install.

[0057] A limiting groove 46 is provided on the side of the center roller 41 near the end seat II 31. The collar 6 is movably sleeved in the limiting groove 46, so that when the cleaning component rotates, the limiting groove 46 can restrict the collar 6 and prevent the cleaning component from having adverse displacement in other directions besides circumferential movement.

[0058] The side of scraper I 62 facing scraper II 63 is in contact with the inner wall of the separator cylinder 5, so that when the cleaning assembly rotates, scraper I 62 can scrape off the deposits, especially carbon deposits, on the inner wall of the separator cylinder 5 in real time.

[0059] The side of scraper rod II 63 facing scraper rod I 62 is in contact with the outer wall of the separator cylinder 5, so that when the cleaning assembly rotates, scraper rod II 63 can scrape off the deposits, especially carbon deposits, on the outer wall of the separator cylinder 5 in real time.

[0060] The side of scraper bar III 64 away from scraper bar II 63 is in contact with the inner wall of roller 32, so that when the cleaning assembly rotates, scraper bar III 64 can scrape off the deposits, especially carbon deposits, on the inner wall of roller 32 in real time.

[0061] The force plate 65 is concave in the direction of rotation of the roller 32, so that the liquid flow guided circumferentially by the liquid flow sprayed from the inclined hole 52 can impact the concave side of the nearby force plate 65, providing a circumferential thrust. This causes the force plate 65 to drive the entire cleaning assembly to rotate slowly circumferentially, causing the three scrapers (scraper I 62, scraper II 63, scraper III 64) to scrape the deposits circumferentially on the inner wall of the roller 32 and the inner and outer walls of the separator 5, respectively. The turbulent liquid flow will carry away the scraped deposits.

[0062] It should be noted that when the three scrapers pass through the inclined hole 52, the impact force of the liquid jetting out through the inclined hole 52 is enhanced, resulting in a stronger thrust in the flow direction of the liquid jet on the three scrapers. This leads to a stronger contact force between scraper I 62 and the separator cylinder 5, and a stronger contact force between scraper III 64 and the roller 32. The enhanced contact force will increase the friction force, and the friction force of the roller 32 on scraper III 64 will increase the power for the rotation of the entire cleaning assembly.

[0063] The rotation of the cleaning component is affected by the distance between it and the inclined hole 52, as well as the friction in different areas. As a result, the rotation speed of the cleaning component is constantly changing during one revolution. The different rotation speeds of the cleaning component at different times will cause the liquid flow around the cleaning component to be affected by it as a whole. In different circumferential areas, it will undergo reversal in different directions and with different reactions, further improving the overall turbulence in the circumferential direction and further improving the effective heat exchange efficiency of the heat transfer oil.

[0064] The scraper rods I 62, II 63, and III 64 have small cross-sectional areas to avoid excessive volume affecting the entire space.
