Description

Technical Field

[0001] The utility model relates to the technical field related to paper composite, and in particular to a material roll supporting and pressing device and a composite bonding and pressing system. Background Art

[0002] The current catering and takeaway industries consume a huge amount of disposable knives, forks and spoons. Common disposable plastic knives, forks and spoons are widely accepted because of their mature production technology, sufficient raw material sources and low prices. However, these plastic knives, forks and spoons are also difficult to recycle and cannot be naturally degraded, which poses a huge challenge to our environment. Due to the country's green and environmentally friendly development concept, paper knives, forks and spoons will be widely promoted and applied.

[0003] The raw material of paper cutlery is multi-layer composite paper. The manufacturing process of multi-layer composite sheet in the prior art is usually to first glue the multi-layer paper, and then roll and composite it through multiple rollers. However, the existing multi-layer composite sheet forming equipment first glues multiple composite papers at one time, and then rolls the multiple composite papers at one time through rollers. For example, a multi-layer paper tape composite equipment disclosed in publication number CN118877606A performs one-time rolling and forming of multi-layer composite sheets.

[0004] For example, when the raw material of the multi-layer composite sheet is 6-layer composite paper, the existing equipment first glues each layer of single paper, and then rolls the 6 layers of single paper at one time to obtain 6-layer composite paper. The problem with this method in the prior art is that the requirements for gluing paper are relatively strict. If the gluing is uneven, it will lead to inconsistent bonding strength between the layers, thereby affecting the overall strength and durability of the composite paper. In addition, during the one-time rolling process, bubbles are easily generated due to the influence of the rolling pressure and the rolling speed, resulting in reduced strength and aesthetics of the composite paper. In particular, during the one-time rolling process, the paper in the middle is prone to bubbles and weak bonding.

[0005] Therefore, the multi-layer composite sheet forming machine in the prior art forms the multi-layer composite sheet by rolling and forming the sheet at one time, which has problems such as inconsistent bonding strength between different papers, easy occurrence of bubbles, and weak bonding. Utility Model Content

[0006] The utility model aims to solve the problems that the multi-layer composite sheet forming machine in the prior art rolls and forms the multi-layer composite sheet at one time, such as inconsistent bonding strength between different papers, easy occurrence of bubbles and weak bonding.

[0007] In order to solve the above-mentioned technical problems, an embodiment of the utility model discloses a material roll supporting and pressing device, comprising a frame, a material roll conveying mechanism, an upstream conveying mechanism, and a pressing mechanism arranged at the top of the frame; and also comprising a material roll supporting mechanism, which is arranged in the accommodating space on the lower side of the frame, and provides a material roll of a sheet material that can be rotatably supported on the material roll supporting mechanism.

[0008] The material roll conveying mechanism includes a first material roll conveying component, a gluing component, and a second material roll conveying component which are arranged in sequence along the conveying direction of a single sheet of material. A single sheet of material from the material roll enters the gluing component via the first material roll conveying component, is coated with glue on one side by the gluing component, and is then conveyed into the laminating mechanism by the second material roll conveying component.

[0009] The upstream conveying mechanism is located on one side of the roll conveying mechanism, receives the sheet to be pressed from the upstream unit and conveys it into the pressing mechanism. The pressing mechanism has a pair of pressing rollers, and the single sheet and the sheet to be pressed synchronously enter the pressing gap between the pair of pressing rollers. The sheet to be pressed is located on the side where the single sheet is coated with adhesive, and the pair of pressing rollers press the single sheet and the sheet to be pressed and output them.

[0010] By adopting the above technical scheme, the support and pressing device of the material roll disclosed in the present application only bonds two layers of composite sheets in each bonding process, one layer is the sheet to be pressed delivered by the upstream unit, and the other layer is a single sheet coated with adhesive. Only two layers of sheets are bonded each time, and the bonding between any two layers of sheets is uniform and not easy to generate bubbles, and the bonding between any two adjacent layers of sheets is relatively uniform and firmly bonded, and the bonded composite sheet has a high strength. And through the action of the pressing roller, the single sheet and the sheet to be pressed are tightly pressed together and finally output from the pressing mechanism.

[0011] Therefore, the material roll supporting and laminating device disclosed in the present application can efficiently convey and bond the pressed sheets, the sheets are relatively stable during conveyance, the structure is simpler and more compact, and the quality of the composite sheets output after lamination is higher and more stable.

[0012] Furthermore, a glue coating chamber is provided at the top of the frame, and a glue basin is also provided in the glue coating chamber. The glue coating assembly includes a rotating glue coating roller and a rotating glue leveling roller. The rotating glue coating roller and the rotating glue leveling roller cooperate with each other to make the glue coating on the sheet material more uniform, so that the composite sheet material can be pressed more firmly, with higher strength and less prone to bubbles.

[0013] The embodiment of the utility model further discloses a composite bonding and pressing system, comprising a plurality of supporting and pressing devices, wherein the plurality of supporting and pressing devices are arranged in sequence along a straight line, wherein in two adjacent supporting and pressing devices, in the arrangement direction of the plurality of supporting and pressing devices, a sheet from a pair of pressing rollers of an upstream supporting and pressing device is conveyed into an upstream conveying mechanism of a downstream supporting and pressing device.

[0014] In the arrangement direction of multiple supporting and pressing devices, a front-end material roll conveying mechanism is also arranged upstream of the upstreammost supporting and pressing device, and the front-end material roll conveying mechanism includes a supporting component supporting the front-end material roll, and a front-end conveying mechanism for conveying the sheet material from the front-end material roll to the upstream conveying mechanism of the upstreammost supporting and pressing device.

[0015] In the composite bonding and pressing system, the number of supporting and pressing devices is N, and the number of material rolls is N+1. Among the two adjacent supporting and pressing devices, the sheet to be pressed from the upstream supporting and pressing device is only bonded with one layer of single sheet after passing through the downstream supporting and pressing device, and the composite sheet output by the most downstream supporting and pressing device includes N+1 layers of single sheets.

[0016] By adopting the above technical scheme, multiple supporting and pressing devices in the composite bonding and pressing system disclosed in the present application are arranged in a straight line in sequence, and then the composite sheets are pasted and pressed in sequence along the arrangement direction of the supporting and pressing devices, and the number and thickness of the composite sheets are gradually increased. Moreover, the composite sheets pasted and pressed each time only include the pasted and pressed composite sheets delivered from the previous process and the single sheets to be pressed. Therefore, the pasting and pressing are more firm, have higher strength and are less likely to generate bubbles.

[0017] Furthermore, when the number of layers of composite sheets to be pasted and pressed is different, the number of multiple supporting pressing devices can be adjusted (increased or reduced) according to demand, which has the advantages of simple structure, flexible and convenient adjustment and good pressing quality.

[0043] As mentioned in the prior art, the pressing and forming schemes of multi-layer composite paper in the prior art are to first apply glue to multiple sheets of paper or sheets at one time, and then bond and press the multiple sheets of paper or sheets at one time. For example, when the raw material of the multi-layer composite sheet is 6-layer composite paper, the existing equipment first applies glue to each layer of single paper, and then rolls and forms 6 layers of single paper at one time to obtain 6-layer composite paper. This pressing and forming scheme has strict requirements on the gluing of paper. If the gluing is uneven, it will lead to inconsistent bonding strength between the layers, thereby affecting the overall strength and durability of the composite paper. In addition, during the one-time rolling process, bubbles are easily generated due to the influence of the rolling pressure and the rolling speed, resulting in reduced strength and aesthetics of the composite paper. Therefore, the scheme of bonding and pressing multi-layer composite paper at one time in the prior art has problems such as inconsistent bonding strength between different papers, easy occurrence of bubbles, and weak bonding.

[0044] In order to solve the above-mentioned technical problems, the present application discloses a supporting and laminating device for a material roll, which includes an upstream conveying mechanism 300, which receives a sheet material 310 to be laminated conveyed from an upstream unit and conveys it into a laminating mechanism 400, and also includes a single sheet material coated with adhesive conveyed by a material roll located on one side of a frame 100 of the device. The single sheet material and the sheet material 310 to be laminated are synchronously conveyed to the laminating mechanism 400 and laminated by the laminating mechanism 400. It should be noted that the sheet material to be laminated received by the upstream conveying mechanism 300 can be a single sheet material conveyed by a previous material roll, or a composite sheet material conveyed by a previous supporting and laminating device and bonded and laminated once or multiple times.

[0045] It should be noted that the supporting and pressing device for the material roll disclosed in this embodiment can be used for adhesively pressing sheets of common paper, plastic, carbon fiber sheets, aluminum-plastic sheets and other sheets that can be adhesively pressed, and this embodiment does not make the sole limitation to this.

[0046] Next, the supporting and pressing device of the material roll disclosed in the utility model is specifically described in detail:

[0047] The implementation method of this embodiment discloses a support and pressing device for a material roll, see Figure 1 The device includes a frame 100, and a material roll conveying mechanism 200, an upstream conveying mechanism 300 and a pressing mechanism 400 are arranged at intervals on the top of the frame 100. It also includes a material roll supporting mechanism 120, which is arranged in a receiving space 110 at the lower side of the frame 100, and a material roll 121 of a sheet material is rotatably supported on the material roll supporting mechanism 120.

[0048] In this embodiment, the frame 100 serves to support the material roll conveying mechanism 200, the upstream conveying mechanism 300 and the pressing mechanism 400 at the top, and also serves to support the material roll support mechanism 120 and the material roll 121 located in the accommodating space 110. Therefore, the frame 100 needs to be configured as a structure with a mounting platform on the top and a accommodating space 110 at the bottom. For example, the frame 100 can be configured as a frame structure with a mounting platform on the top to install the upper structure as required. The material roll 121 providing the sheet material can be mounted on the material roll support mechanism 120. The material roll support mechanism 120 is driven by a motor to unwind or roll the material. Those skilled in the art can adjust and design it according to actual needs, and this embodiment does not make specific limitations on this.

[0049] The material roll conveying mechanism 200 includes a first material roll conveying component 210, a gluing component 220, and a second material roll conveying component 230 which are arranged in sequence along the conveying direction of the single sheet 122. The single sheet 122 from the material roll 121 enters the gluing component 220 via the first material roll conveying component 210, is coated with glue on one side by the gluing component 220, and is then conveyed into the laminating mechanism 400 by the second material roll conveying component 230.

[0050] Specifically, see Figure 1 , the conveying path of a single sheet is as follows Figure 1 As shown by the black solid arrow, the sheet material 310 to be pressed is as follows Figure 1 As shown by the black dotted arrow, the single sheet 122 conveyed by the roll 121 in the accommodating space 110 of the frame 100 is conveyed in sequence through the first roll conveying assembly 210, the gluing assembly 220, and the second roll conveying assembly 230. Therefore, the top of the frame 100 is configured to have an opening to facilitate the transportation of the single sheet 122. In addition, each of the first roll conveying assembly 210, the gluing assembly 220, and the second roll conveying assembly 230 includes a rotating shaft, a rotating bearing, and other structures. For example, the first roll conveying assembly 210 includes a first roll conveying rotating shaft, a rotating bearing, a driving motor, and other components. The driving motor drives the first roll conveying rotating shaft to rotate to improve the efficiency of sheet conveying. The gluing assembly 220 includes a gluing roller, a glue basin 500, a rotating bearing, a driving motor, etc. The driving motor drives the gluing roller to rotate to apply glue to the single sheet 122. Those skilled in the art can design or adjust according to actual needs, and this embodiment does not make specific limitations on this.

[0051] More specifically, the glue coating component 220 coats glue on one side of the single sheet 122. The glue coating component 220 may be provided with one roller or two rollers. When two rollers are provided, the two rollers are in contact with each other and one of them is a glue coating roller and the other is a glue leveling roller. When the glue coating component 220 coats glue on one side of the single sheet 122, the glue coating roller may coat the glue on one side of the single sheet 122 by taking the glue from the glue basin 500 and then performing secondary glue leveling with the glue leveling roller; or the glue coating roller may be provided with multiple glue penetration holes evenly and at intervals, and the glue may be coated on one side of the single sheet 122 after the glue seeps out of the glue penetration holes and is then subjected to secondary glue leveling with the glue leveling roller. Those skilled in the art may design and adjust the coating according to actual needs, and this embodiment does not specifically limit this.

[0052] The upstream conveying mechanism 300 is located at one side of the roll conveying mechanism 200. The upstream conveying mechanism 300 is at least spaced apart from the second roll conveying assembly 230, and is preferably arranged upstream of the second roll conveying assembly 230 along the conveying direction of the sheet material 310 to be pressed. The upstream conveying mechanism 300 receives the sheet material 310 to be pressed conveyed from the upstream unit and conveys it into the pressing mechanism 400. The upstream conveying mechanism 300 includes an upstream conveying roller group, and the upstream conveying roller group can be set in multiple numbers, and the positions of different conveying rollers can be adjusted according to actual needs to ensure that the sheet material 310 to be pressed from the upstream and the single sheet material 122 coated with adhesive are simultaneously or synchronously conveyed to the pressing mechanism 400 for pressing.

[0053] The laminating mechanism 400 has a pair of laminating rollers. The single sheet 122 and the sheet to be laminar 310 enter the laminating gap between the pair of laminating rollers synchronously. The sheet to be laminar 310 is located on the side of the single sheet 122 coated with adhesive. The pair of laminating rollers press and output the single sheet 122 and the sheet to be laminar 310.

[0054] More specifically, the lamination gap between a pair of lamination rollers is adjustable, for example, the gap when laminating two sheets is smaller than the gap when laminating three sheets, and technical personnel in this field can also make adjustments according to actual needs to adapt to and meet different lamination needs.

[0055] With this structural design, the support and laminating device of the material roll disclosed in the present application only bonds two layers of composite sheets in each bonding process, one layer is the sheet to be laminated 310 delivered by the upstream unit, and the other layer is the single sheet 122 coated with adhesive. Only two layers of sheets are bonded each time, and the bonding between any two layers of sheets is uniform and not easy to generate bubbles, and the bonding between any two adjacent layers of sheets is relatively uniform and firmly bonded, and the bonded composite sheet has a high strength. And through the action of the laminating roller, the single sheet 122 and the sheet to be laminated 310 are tightly pressed together and finally output from the laminating mechanism 400.

[0056] Further, take the example of setting up three supporting and pressing devices as an example: the first supporting and pressing device bonds and presses the sheet material conveyed by the front-end material roll conveying mechanism 200 and the single sheet material 122 coated with adhesive to form a two-layer composite sheet material, and the two-layer composite sheet material enters the second supporting and pressing device as the sheet material 310 to be pressed, and the second supporting and pressing device bonds and presses the two-layer composite sheet material and the single sheet material 122 coated with adhesive to form a three-layer composite sheet material, and the three-layer composite sheet material enters the third supporting and pressing device as the sheet material 310 to be pressed, and the third supporting and pressing device bonds and presses the three-layer composite sheet material and the single sheet material 122 coated with adhesive to form a four-layer composite sheet material, and finally outputs the bonded four-layer composite sheet material. Technical personnel in this field can adjust the number of supporting and pressing devices according to actual needs.

[0057] Therefore, the material roll supporting and laminating device disclosed in the present application can efficiently convey and bond the pressed sheets, the sheets are relatively stable during conveyance, the structure is simpler and more compact, and the quality of the composite sheets output after lamination is higher and more stable.

[0058] Further, the structures of the glue basin 500, the glue coating assembly 220, etc. in the support and pressing device for the material roll disclosed in this embodiment are described:

[0059] See also Figure 2 and Figure 3 , a gluing chamber 130 is provided at the top of the frame 100, and the gluing chamber 130 is preferably set to a semi-open structure, for example, the top has an opening, so as to facilitate the observation of the conveying and gluing of the sheet material, and the gluing chamber 130 also has a side wall for supporting the internal conveying roller, glue basin 500 and other components. In this embodiment, the material roll conveying mechanism 200 is located in the gluing chamber 130. The glue basin 500 is located below the gluing assembly 220 and close to the side of the material roll supporting mechanism 120, and glue is stored in the glue basin 500.

[0060] The glue coating assembly 220 includes a rotating glue coating roller 221 and a rotating glue leveling roller 222. The rotating glue coating roller 221 is rotatably disposed above the glue basin 500 and its lower portion is located in the glue basin 500, wherein the lower peripheral surface of the rotating glue coating roller 221 is at least partially immersed below the liquid level of the glue in the glue basin 500. The rotating glue leveling roller 222 is rotatably disposed on the side of the rotating glue coating roller 221 away from the glue basin 500, and is in contact with the peripheral surface of the opposite portion of the rotating glue coating roller 221 to form a transmission roller group, and the peripheral surface of the rotating glue leveling roller 222 away from the rotating glue coating roller 221 is in contact with one side of the single sheet 122 from the first material roll conveying assembly 210.

[0061] Specifically, in the present embodiment, the glue coating and glue leveling are performed by the cooperation of the rotating glue coating roller 221 and the rotating glue leveling roller 222, so that the rotating glue leveling roller 222 can evenly coat a layer of glue on one side of the single sheet 122. Because after the rotating glue coating roller 221 is glued with glue from the glue basin 500, the glue on the surface of the rotating glue coating roller 221 may be uneven, for example, the glue in some areas is too thick or too thin, and by setting and rotating the glue coating roller 221 in close contact with the rotating glue leveling roller 222, the glue on the surface can be scraped evenly and then coated on one side of the single sheet 122 from the first material roll conveying component 210. The lower outer peripheral surface of the rotating glue coating roller 221 rotatably arranged above the glue basin 500 is at least partially immersed below the liquid surface of the glue in the glue basin 500, that is, the rotating glue coating roller 221 is partially located below the liquid surface of the glue in a stationary state, and when rotating, it can carry away the glue coating and spread the glue by rotating the glue spreading roller 222.

[0062] Furthermore, in a preferred implementation disclosed in this embodiment, see Figure 2 A glue spreading roller driving motor 224 is provided on one side of the rotating glue spreading roller 222, and the rotating glue spreading roller 222 is driven by the glue spreading roller driving motor 224 to rotate, and then the rotating glue coating roller 221 is driven to glue by the roller group structure formed by the rotating glue spreading roller 222 and the rotating glue coating roller 221, and a glue coating deceleration roller 225 is also provided on one side of the rotating glue coating roller 221, and the glue coating deceleration roller 225 can brake the rotating glue coating roller 221 to prevent the rotating glue coating roller 221 from rotating too fast, thereby improving the gluing effect. A glue coating roller adjustment portion 223 is also provided, and the glue coating roller adjustment portion 223 is used to adjust the positions of the rotating glue spreading roller 222 and the rotating glue coating roller 221. Therefore, an adjustment groove 450 can be provided on the side wall of the glue coating chamber 130, and then an adjustment slider 440 is provided in the adjustment groove 450 to achieve the adjustment position. Those skilled in the art can also provide other mechanisms for adjustment, such as providing a screw adjustment mechanism, a worm gear adjustment mechanism, etc., and cooperate with guide rails and slide grooves to achieve the position adjustment of the rotating glue spreading roller 222 and the rotating glue coating roller 221.

[0063] Therefore, in this embodiment, the rotating glue-distributing roller 222 further evens out the glue on the rotating glue-coating roller 221 through contact with the rotating glue-coating roller 221, and transfers it to the single sheet 122. At the same time, the outer peripheral surface of the rotating glue-distributing roller 222 away from the rotating glue-coating roller 221 abuts against one side of the single sheet 122 from the first material roll conveying assembly 210 to achieve the application of glue, which can achieve uniform application and improve production efficiency. It can also be adjusted according to different glue coating needs and process requirements, such as adjusting the speed, pressure and other parameters of the glue-coating roller to adapt to sheets of different materials and sizes.

[0064] Preferably, the diameter of the rotating glue-distributing roller 222 is equal to or greater than the diameter of the rotating glue-coating roller 221. And the outer rings of the rotating glue-coating roller 221 and the rotating glue-distributing roller 222 are both coated with a layer of flexible glue coating. For example, the diameter of the rotating glue-distributing roller 222 is equal to the diameter of the rotating glue-coating roller 221, or the diameter of the rotating glue-distributing roller 222 is greater than the diameter of the rotating glue-coating roller 221 by 5 mm, 10 mm, 15 mm, etc. The flexible glue coating layer coated on the outer rings of the rotating glue-coating roller 221 and the rotating glue-distributing roller 222 can be a flexible material such as rubber, silicone, polyurethane, etc.

[0065] Further preferably, in the support and pressing device for the material roll disclosed in the utility model, see Figure 2 The bottom of the glue basin 500 is provided with a rotation adjustment assembly, which includes a rotation bracket 510 and a rotation swing arm 520. The lower end of the rotation swing arm 520 is rotatably disposed on the frame 100. The bottom of the glue basin 500 is disposed at the upper end of the rotation bracket 510, and the rotation bracket 510 is movably disposed at the upper end of the rotation swing arm 520. The rotation swing arm 520 can drive the rotation bracket 510 and the glue basin 500 to move relative to the frame 100.

[0066] It should be noted that, in this embodiment, the cooperation of the rotating swing arm 520 and the rotating bracket 510 actually forms a connecting rod mechanism, more specifically, a crank rocker mechanism, so the rotating swing arm 520 can drive the rotating bracket 510 and the glue basin 500 to move relative to the frame 100. And the bottom of the glue basin 500 and the upper end of the rotating bracket 510 are connected by a relatively rotatable manner such as hinged connection and pivot connection, that is, the bottom of the glue basin 500 and the rotating bracket 510 can rotate relative to each other. The rotating bracket 510 and the rotating swing arm 520 are also connected by a relatively rotatable manner such as hinged connection and pivot connection to ensure that the rotating swing arm 520 can drive the rotating bracket 510 and the glue basin 500 to move relative to the frame 100.

[0067] With the above-mentioned structural design, the rotating bracket 510 is the main component supporting the glue basin 500, which can firmly mount the glue basin 500 on the upper end of the rotating swing arm 520. The rotating bracket 510 has sufficient rigidity and stability to ensure that the glue basin 500 will not shake or tilt during movement. The lower end of the rotating swing arm 520 is rotatably set on the frame 100, which enables it to rotate around a fixed axis. At the same time, the upper end of the rotating swing arm 520 is connected to the rotating bracket 510. By adjusting the angle of the rotating swing arm 520, the position and height of the glue basin 500 can be changed. The rotating adjustment component allows the glue basin 500 to be flexibly moved relative to the frame 100, thereby meeting the different requirements for the position and height of the glue basin 500 in different application scenarios. The rotating bracket 510 and the rotating swing arm 520 have sufficient rigidity and stability. Therefore, even during the movement, the glue basin 500 can remain stable without shaking or tilting. For example, when the glue basin 500 needs to be cleaned or glue needs to be added, the rotating swing arm 520 can be used to drive the rotating bracket 510 and the glue basin 500 to move relative to the frame 100 to facilitate cleaning or adding glue.

[0068] Next, the specific structures of the first roll conveying assembly 210 and the second roll conveying assembly 230 of the roll supporting and pressing device disclosed in this embodiment are further explained:

[0069] Further preferably, the first material roll conveying assembly 210 includes a first material roll conveying roller, both ends of which are rotatably arranged on the side walls of the glue coating chamber 130, and the first material roll conveying roller is located at the upstream end of the rotating glue coating roller 222 on the conveying path of the single sheet 122.

[0070] The second material roll conveying assembly 230 includes a second material roll conveying roller, both ends of which are rotatably arranged on the side walls of the gluing chamber 130 , and the second material roll conveying roller is located at the downstream end of the rotating glue roller 222 on the conveying path of the single sheet 122 .

[0071] The single sheet 122 passes through the first material roll conveying roller, the rotating glue leveling roller 222, and the second material roll conveying roller in sequence. The conveying path of the single sheet 122 extends in an "S" shape between the first material roll conveying roller, the rotating glue leveling roller 222, and the second material roll conveying roller, and one side of the single sheet 122 always abuts against part of the outer circumference of the rotating glue leveling roller 222. Through this structural design, the internal space layout is optimized, and at the same time, one side of the single sheet 122 always abuts against part of the outer circumference of the rotating glue leveling roller 222 to ensure uniform glue coating.

[0072] Specifically, in this embodiment, through the design of the "S"-shaped path, the first material roll conveying roller, the rotating glue roller 222 and the second material roll conveying roller can be compactly arranged in the limited glue coating room 130. This layout not only saves space, but also makes the entire glue coating system more compact and efficient. During the conveying process of the sheet material, through the "S"-shaped path, the space in the glue coating room 130 can be more effectively utilized, avoiding the space waste and layout difficulties that may be caused by linear conveying.

[0073] More specifically, when the sheet passes through the rotating glue-distributing roller 222, the glue can be more evenly applied to the sheet due to the cooperation between the rotating glue-distributing roller 222 and the rotating glue-applying roller 221, as well as the tension change caused by the "S"-shaped path. This uniform glue-applying effect helps to improve product quality and consistency. In the "S"-shaped path, the sheet will be stretched and bent to a certain extent during the conveying process, which helps to reduce bubbles in the glue and further improve the glue-applying quality. And this design can adapt to sheets of different sizes, thicknesses and materials. By adjusting the relative position and tension between the first material roll conveying roller, the rotating glue-distributing roller 222 and the second material roll conveying roller, sheets of different specifications can be easily handled.

[0074] More preferably, see Figure 3 The second material roll conveying roller can be movably supported on the side wall of the gluing chamber 130 relative to the first material roll conveying roller, wherein the two ends of the second material roll conveying roller are rotatably arranged in the corresponding shaft holes 233 on the side wall of the gluing chamber 130, and the radial dimension of the shaft hole 233 is larger than the shaft end dimension of the two ends of the second material roll conveying roller.

[0075] Specifically, the shaft hole 233 can be set to various shapes of shaft holes 233, such as a circular hole, an elliptical hole, a waist-shaped hole, etc., and the radial size is larger than the shaft end size at both ends of the second material roll conveying roller, so as to meet the needs of the second material roll conveying roller in the shaft hole 233. In this embodiment, it is preferably set to a circular hole, which has a higher degree of adjustment freedom.

[0076] Adjustment components are respectively provided at both ends of the second material roll conveying roller, and each adjustment component includes a movable telescopic rod 231 and an adjustment swing arm 232. In each adjustment component, one end of the movable telescopic rod 231 is rotatably provided on the outer surface of the side wall of the glue coating chamber 130, and the other end is rotatably connected to one end of the adjustment swing arm 232, and the other end of the adjustment swing arm 232 is rotatably sleeved on the portion of the corresponding end of the second material roll conveying roller extending out of the shaft hole 233, and the two movable telescopic rods 231 move synchronously with respect to the side wall of the glue coating chamber 130, and a pair of limit blocks are provided on both sides of each adjustment swing arm 232.

[0077] Specifically, in this embodiment, the movement of the two movable telescopic rods 231 relative to the side wall of the glue coating chamber 130 is synchronous, which means that the two movable telescopic rods 231 are simultaneously extended and rotated synchronously. The purpose of this design is to ensure that the adjustment of the two ends of the shaft of the second material roll conveying roller is synchronous. The synchronous movement of the movable telescopic rods 231 ensures that the adjustment of the two ends of the conveying roller is consistent, avoiding the conveying problem caused by the inconsistent height or position of the two ends, for example, it can avoid the second material roll conveying roller from tilting, for example, the two movable telescopic rods 231 are simultaneously contracted by 6mm, 8mm, 10mm, etc., or the two movable telescopic rods 231 are simultaneously extended by 6mm, 9mm, 12mm, etc. Or the two movable telescopic rods 231 are simultaneously rotated clockwise or counterclockwise by 15°, 20°, 30°, etc. Through this synchronous action, the adjustment swing arms 232 at the two ends of the shaft of the second material roll conveying roller can also be adjusted synchronously, and finally the adjustment of the second material roll conveying roller is achieved. The synchronous control of the two movable telescopic rods 231 can be controlled by a PLC, a controller, etc., which is not specifically limited in this embodiment.

[0078] More specifically, in this embodiment, the height or position of the second material roll conveying roller can be accurately adjusted by extending and retracting the movable telescopic rod 231 to meet the material conveying requirements of different specifications or thicknesses. The adjustment swing arm 232 is further used to make the adjustment process more flexible, and the slight angle or position of the conveying roller can be adjusted. The connection mode of the movable telescopic rod 231 and the adjustment swing arm 232 is a rotatable connection. This design can reduce the influence of the force generated by vibration or impact on the conveying roller, thereby improving the stability of the system. The design can adapt to material rolls of different sizes, weights and materials. By adjusting the height and position of the conveying roller, the stability and accuracy of the material roll 121 during the conveying process can be ensured. The design of the limit block can prevent the adjustment swing arm 232 from excessively rotating or moving during the adjustment process, thereby avoiding safety accidents caused by equipment failure or misoperation. Through a reasonable limit design, it can be ensured that the system is always in a safe state during operation.

[0079] Next, the pressing mechanism 400 in the supporting pressing device for the material roll disclosed in this embodiment is explained in detail:

[0080] See also Figure 2 and Figure 3The laminating mechanism 400 has a pair of laminating rollers, which include an active laminating roller 410 and a driven laminating roller 420 arranged in the vertical direction, and a laminating gap extending in the horizontal direction is provided between the active laminating roller 410 and the driven laminating roller 420. It should be noted that the laminating gap extends in the horizontal direction because the single sheet 122 and the sheet to be laminar 310 are transported in the horizontal direction, so this design can ensure bonding and laminating. In addition, laminating matching rollers 470 are also provided on both sides of the active laminating roller 410 and the driven laminating roller 420.

[0081] The active lamination roller 410 is located below the driven lamination roller 420, and a driving unit is arranged outside one side shaft end of the active lamination roller 410. The driving unit includes a lamination driving motor 430 fixedly arranged on the frame 100 and drivingly connected to the corresponding side shaft end of the active lamination roller 410. The lamination driving motor 430 fixedly arranged on the frame 100 and drivingly connected to the corresponding side shaft end of the active lamination roller 410 provides a stable and controllable power source for the lamination roller. This design makes the lamination process more precise and efficient.

[0082] The driven pressing roller 420 is rotatably arranged above the active pressing roller 410, and the two ends of the driven pressing roller 420 are movably arranged in two adjusting slots 450 on the frame 100 in the vertical direction through the adjusting slider 440, and the two ends of the driven pressing roller 420 are rotatably arranged on the corresponding adjusting slider 440. The driven pressing roller 420 is movably arranged in two adjusting slots 450 on the frame 100 in the vertical direction through the adjusting slider 440. This design not only allows the height of the driven pressing roller 420 to be flexibly adjusted, but also ensures the compactness and stability of the structure. In addition, the sliding guide unit adapted to the adjusting slider 440 provided in the adjusting slot 450 provides stable guidance and support for the movement of the adjusting slider 440.

[0083] A pair of adjusting drive motors 460 are also provided on the frame 100. The pair of adjusting drive motors 460 are respectively provided above a corresponding adjusting slider 440. The output end of the adjusting drive motor 460 is connected to the corresponding adjusting slider 440 and can drive the adjusting slider 440 to slide in the vertical direction in the adjusting slot 450. The adjusting slot 450 is also provided with a sliding guide unit adapted to the adjusting slider 440. The adjusting drive motor 460 provided above the adjusting slider 440 is connected to the corresponding adjusting slider 440 through the output end and can drive the adjusting slider 440 to slide in the vertical direction in the adjusting slot 450. This design allows the height of the driven laminating roller 420 to be adjusted quickly and accurately as needed, thereby adapting to materials of different thicknesses or different laminating requirements.

[0084] For example, the lamination drive motor 430 drives the active lamination roller 410 to rotate. When the lamination gap needs to be adjusted, a pair of adjustment drive motors 460 act synchronously, and then simultaneously drive the adjustment slider 440 to move downward or upward a certain distance, and then complete the adjustment of the lamination gap. It should be noted that the adjustment drive can also be set as a cylinder or other adjustment mechanism. Further, for example, when the lamination gap needs to be adjusted from a 3mm gap to a 4mm gap, a pair of adjustment drive motors 460 act synchronously, and then simultaneously drive the adjustment slider 440 to move upward 1mm, and the adjusted lamination gap becomes a 4mm gap.

[0085] The web supporting and laminating device disclosed in this embodiment further includes a synchronous conveying roller 600, both ends of which are rotatably arranged on the side wall of the gluing chamber 130, located at one end of the gluing chamber 130 close to the pair of laminating rollers, and at the upstream side of the pair of laminating rollers, that is, the synchronous conveying roller 600 is arranged at the front end of the pair of laminating rollers. An auxiliary standby roller 610 is also arranged on one side of the synchronous conveying roller 600.

[0086] As mentioned above, the upstream conveying mechanism 300 includes an upstream conveying roller, both ends of which are rotatably disposed on the side wall of the gluing chamber 130 and located at one end of the gluing chamber 130 away from the pair of pressing rollers.

[0087] In the vertical direction, the upper end of the rotating glue-distributing roller 222 is higher than the upper end of the rotating glue-coating roller 221, the upper end of the first material roll conveying roller is aligned with the upper end of the rotating glue-distributing roller 222 in the horizontal direction, the lower end of the second material roll conveying roller is lower than the upper end of the rotating glue-distributing roller 222, and the upper end is lower than the upper end of the synchronous conveying roller 600, and the lower end of the upstream conveying roller is higher than the upper end of the synchronous conveying roller 600, and the upper end of the synchronous conveying roller 600 is higher than the lamination gap of a pair of lamination rollers.

[0088] It should be noted that the upper end or lower end mentioned in this embodiment refers to the upper end or lower end of the outer peripheral end surface of the corresponding roller. The upper end of the rotating glue-distributing roller 222 is higher than the upper end of the rotating glue-distributing roller 221. Such a design can ensure that during the process of glue coating and glue-distributing, the material can smoothly transition from the glue-distributing roller to the glue-distributing roller, avoiding the problem of material accumulation or stretching caused by the height difference. The upper end of the first material roll conveying roller is aligned with the upper end of the rotating glue-distributing roller 222 in the horizontal direction, which helps the smooth transition of the material during the conveying process and reduces the material offset or damage caused by position deviation. The lower end of the second material roll conveying roller is lower than the upper end of the rotating glue-distributing roller 222, and the upper end is lower than the upper end of the synchronous conveying roller 600. Such a design enables the material to form a certain level during the conveying process, avoids mutual interference between materials at different stages, and improves the conveying efficiency. The lower end of the upstream conveying roller is higher than the upper end of the synchronous conveying roller 600. Such a design also ensures that the material has enough buffer and adjustment space before entering the synchronous conveying stage. The upper end of the synchronous conveying roller 600 is higher than the lamination gap of a pair of lamination rollers. This design ensures that during the lamination process, the material can smoothly enter the lamination gap, avoiding uneven lamination or material damage caused by height difference, and ensuring that the sheet receives uniform pressure.

[0089] The single sheet 122 from the second material roll conveyor roller and the sheet to be laminated 310 from the upstream conveyor roller pass through the upper end of the synchronous conveyor roller 600 synchronously. This design ensures the precise alignment and synchronous movement of the sheets before lamination, and avoids misalignment or poor lamination caused by asynchronous sheet conveying. And when passing through the synchronous conveyor roller 600, the side of the single sheet 122 coated with adhesive faces upward, and the sheet to be laminated 310 is located above the single sheet 122. This design ensures that the adhesive will not be contaminated or damaged during the conveying and lamination process, and also helps the adhesive to fully contact and bond with the sheet to be laminated 310. At the upper end of the synchronous conveyor roller 600, the angle between the extension direction of the sheet to be laminated 310 and the single sheet 122 is between 15° and 30°. Please refer to Figure 1 The conveying path of a single sheet 122 is as follows: Figure 1 As shown by the black solid arrow, the sheet material 310 to be pressed is as follows Figure 1 Indicated by the black dashed arrow.

[0090] Furthermore, by designing an angle between the extension direction of the sheet material 310 to be laminated and the single sheet material 122, the adhesive can be more evenly distributed on the surface of the single sheet material 122 during the lamination process, thereby avoiding poor lamination or insufficient bonding force due to uneven distribution of the adhesive. For example, the angle can be adjusted to 15°, 20°, 25°, 30°, etc. as needed.

[0091] In the roll support and pressing device disclosed in this embodiment, the roll support mechanism 120 includes a roll support shaft, which is rotatably arranged in the accommodating space 110, and a single sheet roll 121 is sleeved on the roll support shaft. The roll support shaft can be set as an air shaft or other structure, and a driving motor can be set on one side of the roll support shaft to drive the roll 121 to rotate and feed the material.

[0092] Example 2

[0093] The implementation method of this embodiment also discloses a composite bonding and pressing system, see Figure 4 , including multiple supporting and pressing devices. The multiple supporting and pressing devices are arranged in sequence along a straight line to form a continuous production process. Among them, in two adjacent supporting and pressing devices, in the arrangement direction of the multiple supporting and pressing devices, the sheet from a pair of pressing rollers of the upstream supporting and pressing device is conveyed into the upstream conveying mechanism 300 of the downstream supporting and pressing device, achieving seamless connection and greatly improving production efficiency.

[0094] In the arrangement direction of multiple supporting and pressing devices, a front-end material roll conveying mechanism is also arranged upstream of the most upstream supporting and pressing device. The front-end material roll conveying mechanism includes a supporting component and a front-end conveying mechanism. The supporting component supports the front-end material roll, and the front-end conveying mechanism conveys the sheet material from the front-end material roll to the upstream conveying mechanism 300 of the most upstream supporting and pressing device.

[0095] For example, if the most upstream supporting and pressing device is defined as the first supporting and pressing device, a front end material roll conveying mechanism is also provided upstream (front end) of the first supporting and pressing device, and the front end material roll conveying mechanism has a front end material roll. The sheet material of the front end material roll (in this case, the sheet material 310 to be pressed) is conveyed to the first supporting and pressing device, and is bonded and pressed with the single sheet material 122 coated with adhesive by the first supporting and pressing device. That is to say, through this structural design, the composite sheet material output by the first supporting and pressing device is a two-layer composite sheet material that has been bonded and pressed once.

[0096] In the composite bonding and pressing system, the number of supporting and pressing devices is N, and the number of material rolls 121 is N+1, wherein in two adjacent supporting and pressing devices, the sheet to be pressed from the upstream supporting and pressing device is only bonded with one layer of single sheet after passing through the downstream supporting and pressing device, and the composite sheet output by the most downstream supporting and pressing device includes N+1 layers of single sheets.

[0097] Specifically, when the number of supporting and pressing devices is 3, the number of material rolls 121 is 4, and the number of layers of the composite sheet material obtained is 4, which is bonded 3 times. When the number of supporting and pressing devices is 6, the number of material rolls 121 is 7, and the number of layers of the composite sheet material obtained is 7, which is bonded 6 times. Take the arrangement of 3 supporting and pressing devices as an example:

[0098] The first supporting and pressing device bonds and presses the sheet material conveyed by the front-end material roll conveying mechanism and the single sheet material 122 coated with adhesive to form a two-layer composite sheet material. The two-layer composite sheet material enters the second supporting and pressing device as the sheet material 310 to be laminated. The second supporting and pressing device bonds and presses the two-layer composite sheet material and the single sheet material 122 coated with adhesive to form a three-layer composite sheet material. The three-layer composite sheet material enters the third supporting and pressing device as the sheet material 310 to be laminated. The third supporting and pressing device bonds and presses the three-layer composite sheet material and the single sheet material 122 coated with adhesive to form a four-layer composite sheet material. Finally, the four-layer composite sheet material after bonding is output. Those skilled in the art can adjust the number of supporting and pressing devices according to actual needs. More preferably, please refer to Figure 4 The composite bonding and pressing system disclosed in this embodiment is provided with 8 supporting and pressing devices, and 9 material rolls 121 are provided, and the composite sheet material finally obtained is a composite sheet material of 9 layers. Its bonding and pressing method is the same as that of the aforementioned 3 supporting and pressing devices, and the only difference is that the bonding and pressing times are more.

[0099] By adopting the above-mentioned technical scheme, a plurality of supporting and pressing devices in the composite bonding and pressing system disclosed in the present application are arranged in sequence along a straight line, and then the composite sheets are pasted and pressed in sequence along the arrangement direction of the supporting and pressing devices, and the number and thickness of the composite sheets are gradually increased. Moreover, the composite sheets pasted and pressed each time only include the pasted and pressed composite sheets conveyed from the previous process and the single sheet 122 to be pressed. Therefore, the pasting and pressing are more firm, have higher strength and are less likely to generate bubbles.

[0100] Furthermore, when the number of layers of composite sheets to be pasted and pressed is different, the number of multiple supporting pressing devices can be adjusted (increased or reduced) according to demand, which has the advantages of simple structure, flexible and convenient adjustment and good pressing quality.

[0101] See also Figure 4In the composite bonding and pressing system disclosed in the implementation method of this embodiment, in the arrangement direction of multiple supporting and pressing devices, a pair of auxiliary pressing rollers 700 are further arranged downstream of a pair of pressing rollers of the most downstream supporting and pressing device, and an auxiliary pressing gap extending in the horizontal direction is provided between the pair of auxiliary pressing rollers 700, and the auxiliary pressing gap is aligned with the pressing gap of the most downstream supporting and pressing device in the horizontal direction. The setting of the auxiliary pressing rollers 700 enables the composite material after being pressed by the most downstream supporting and pressing device to be subjected to the pressing force again for secondary pressing and strengthening, thereby further enhancing the pressing effect. This secondary pressing helps to eliminate possible tiny bubbles and improve the uniformity and firmness of the bonding. The auxiliary pressing gap is aligned with the pressing gap of the most downstream supporting and pressing device in the horizontal direction, ensuring the continuity and stability of the composite material during the pressing process, and avoiding uneven pressing or material damage caused by position deviation.

[0102] Finally, the working process of the composite bonding and pressing system disclosed in this embodiment, which is provided with 8 supporting and pressing devices and 9 material rolls 121, is briefly described:

[0103] See also Figure 4 ,exist Figure 4 The direction of bonding and laminating the composite sheet is from right to left in sequence. The rightmost roll 121 is the first roll 121. The first roll 121 conveys the first single sheet 122 (sheet 310 to be laminated) to the first supporting and laminating device. The first supporting and laminating device conveys the single sheet 122 of the second roll 121 arranged in the accommodating space 110 at the lower side of the frame 100 and coats it with glue. Then, the first single sheet 122 (sheet 310 to be laminated) is conveyed to the laminating device synchronously. The bonding mechanism 400 bonds and presses the double-layer composite sheet, which is then conveyed to the second supporting and pressing device as the sheet 310 to be pressed. In the second supporting and pressing device, the double-layer composite sheet and the single sheet 122 coated with adhesive are bonded and pressed into a three-layer composite sheet, which are then bonded and pressed in sequence. Finally, a nine-layer composite sheet is formed by bonding and pressing in the eighth supporting and pressing device, and is pressed for the second time by the auxiliary pressing roller 700 to eliminate possible tiny bubbles and improve the uniformity and firmness of the bonding.
