Description

Technical Field

[0001] This utility model relates to the technical field of hot melt adhesive laminating equipment, and in particular to a multifunctional hot melt adhesive production and laminating device. Background Technology

[0002] Hot melt adhesive lamination is a process that bonds two or more substrates together using molten hot melt adhesive. It is widely used in the production of packaging materials, textile fabrics, and other industries. The lamination process typically involves continuous steps such as unwinding, applying adhesive, pressing, and rewinding.

[0003] However, in traditional laminating equipment, the freshly laminated material is often still at a high temperature after coating and pressing, with the hot melt adhesive in a semi-molten or softened state. If winding is performed directly at this point, it can easily lead to adhesion between layers, resulting in the entire roll being scrapped. Furthermore, the substrate at high temperatures is prone to tensile deformation, severely affecting the flatness and structural stability of the finished product. While existing equipment partially utilizes natural air cooling, its cooling efficiency is low and cannot meet the demands of high-speed production.

[0004] Furthermore, in the final winding stage, different production orders often correspond to substrates of different widths, and most existing winding mechanisms use fixed-width limiting structures or lack effective limiting adjustment methods. When changing to substrates of different widths, operators find it difficult to quickly and accurately adjust the winding limits, which can easily lead to substrate misalignment and uneven edges of the roll during winding, thus affecting subsequent packaging and use, and even requiring machine shutdown for tedious mechanical adjustments, reducing production efficiency.

[0005] Therefore, this utility model proposes a multifunctional hot melt adhesive production and compounding device to overcome the shortcomings of the prior art. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a multifunctional hot melt adhesive production and laminating device, which aims to improve the problems of low cooling and shaping efficiency leading to easy adhesion and deformation of finished products, and poor adaptability and low winding quality caused by the lack of flexible adjustment means in the winding mechanism in the existing hot melt adhesive laminating device.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a multifunctional hot melt adhesive production and compounding device, comprising: a fixed bracket, a first and a second discharge roller rotatably connected to the fixed bracket, a hot melt adhesive machine and an adhesive pump fixed to the fixed bracket, and a first and a second extrusion shaft rotatably connected to the fixed bracket; as well as a water cooling component and an adjustment component;

[0008] The adjusting component has the structural features of screw drive and guide rail, including a second fixed plate and a slide rail fixed to the fixed bracket, a threaded rod rotatably connected to the second fixed plate, and a moving block threadedly connected to the threaded rod and slidably connected to the slide rail.

[0009] Furthermore, the adjustment assembly also includes a third fixing plate, a support block fixed to the third fixing plate, a take-up roller rotatably connected to the support block, and a limiting ring sleeved on the take-up roller and connected to the moving block; the adjustment assembly achieves adjustment and limiting of the take-up width by driving the limiting ring to move laterally on the take-up roller through the moving block.

[0010] Preferably, the water-cooling assembly includes a water pump, a first fixed plate, and a water-cooled roller assembly rotatably connected to the fixed bracket. The water pump is connected to a water inlet pipe. The first fixed plate has a first connecting pipe connected to the water inlet pipe. The first connecting pipe is connected to a third connecting pipe through a second connecting pipe. The third connecting pipe is connected to a fifth connecting pipe through a fourth connecting pipe. The fifth connecting pipe is connected to a water outlet pipe through a sixth connecting pipe. The cooling water flows through the interior of the water-cooled roller assembly. This multi-stage interconnected structure constructs a complete cooling circulation loop, ensuring that the cooling medium can fully flow through the rollers to remove heat.

[0011] Preferably, the adjustment assembly further includes a handle fixedly connected to the end of the threaded rod, and a limiting block fixedly connected to the side of the second fixed plate and located on the moving path of the moving block; the handle is used to facilitate manual force application for adjustment, and the limiting block is used to prevent the moving block from exceeding the adjustment stroke and falling off.

[0012] Preferably, the slide rail has a groove inside, and one side of the moving block is slidably engaged inside the groove; this groove engagement structure can effectively limit the degree of freedom of the moving block, prevent it from rotating with the threaded rod, and ensure the stability of linear motion.

[0013] Preferably, the support blocks are disposed at both ends of the take-up roller, and the take-up roller is fixed above the third fixing plate by the support blocks; this double-end support method can significantly improve the stability of the take-up roller when rotating at high speed.

[0014] Preferably, the device further includes a first roller group and a second roller group rotatably connected inside the fixed bracket. The first roller group is located between the first discharge roll and the first extrusion shaft, and the second roller group is located between the second discharge roll and the second extrusion shaft. Guided by the roller group, the substrate can be smoothly and accurately conveyed to the gluing and laminating station.

[0015] Preferably, the device further includes a third roller assembly rotatably connected inside the fixed bracket, the third roller assembly being located between the first extrusion shaft and the water-cooling assembly; this arrangement plays a connecting role, smoothly transitioning the freshly compounded material to the cooling process.

[0016] Preferably, the device further includes a conveyor roller rotatably connected to the fixed bracket, the conveyor roller being located between the water-cooling assembly and the winding roller; the conveyor roller further optimizes the conveying path of the finished material, ensuring that it can enter the winding area at an appropriate angle.

[0017] This utility model has the following beneficial effects:

[0018] 1. This utility model solves the problem of easy adhesion and deformation of materials due to low natural cooling efficiency after hot melt adhesive lamination by setting a water cooling component after the lamination process and using a water pump to drive cooling water to form a circulating flow loop inside the multi-stage pipeline and water-cooled roller assembly. It achieves the technical effect of rapidly reducing the material temperature, accelerating the curing and shaping of hot melt adhesive, and ensuring the flatness and structural stability of the finished product.

[0019] 2. This utility model solves the problem that the existing winding mechanism lacks flexible limit adjustment function and is difficult to adapt to substrates of different widths by setting an adjustment component with a screw drive and slide rail guide structure, and using a rotating screw rod to drive the moving block and the limiting ring to make linear reciprocating motion. It achieves the technical effect of being able to accurately adjust the limit distance according to the width of the material, ensuring that the edge of the finished roll is neat and uniform, and improving the winding quality.

[0020] 3. This utility model solves the problem of the moving block easily rotating or wobbling with the rod in single screw transmission by opening a groove on the surface of the slide rail and making the moving block slide and engage in it, thus achieving the technical effect of limiting the circumferential rotation of the moving block, enhancing the stability of the adjustment process and the guiding accuracy.

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Reference Figures 1-5This utility model provides an embodiment of a multifunctional hot melt adhesive production and laminating device, comprising a fixed bracket 15, and a first discharge roll 1 and a second discharge roll 2 rotatably connected to one side of the fixed bracket 15. The fixed bracket 15 serves as the mounting base for the entire device, and the first discharge roll 1 and the second discharge roll 2 are used to install and provide two different substrate rolls, respectively. A hot melt adhesive machine 3 is fixedly connected to the top of the fixed bracket 15, and an adhesive pump 4 is connected to the side of the hot melt adhesive machine 3. The hot melt adhesive machine 3 is used to heat solid adhesive to a molten state, and the adhesive pump 4 is used to transport the molten adhesive to the coating station. Inside the fixed bracket 15, a first extrusion shaft 9 and a second extrusion shaft 10 are rotatably connected, and the first extrusion shaft 9 and the second extrusion shaft 10 are used to apply pressure to the two substrates after adhesive coating to achieve lamination. To achieve precise delivery of the substrate, the fixed bracket 15 is also rotatably connected with a first roller group 7 and a second roller group 8. The first roller group 7 is located between the first discharge roll 1 and the first extrusion shaft 9, and the second roller group 8 is located between the second discharge roll 2 and the second extrusion shaft 10, respectively, to guide the two substrates into the processing area.

[0030] It also includes a water-cooling component 5 disposed on one side of the fixed bracket 15, and an adjustment component 6 disposed at the end of the fixed bracket 15. The water-cooling component 5 and the fixed bracket 15 form a cooling circulation cooperation, and the adjustment component 6 and the fixed bracket 15 form an adjustable winding cooperation.

[0031] The water-cooling assembly 5 includes a first fixing plate 12 fixedly connected to the side wall of the fixing bracket 15, and a water-cooling roller assembly 14 rotatably connected to the inner wall of the fixing bracket 15. A water pump 501 is fixedly connected below the first fixing plate 12, and the output end of the water pump 501 is connected to a water inlet pipe 502. A first connecting pipe 503 communicating with the water inlet pipe 502 is provided inside the first fixing plate 12. The water-cooling roller assembly 14 includes a plurality of rollers. The end of the first connecting pipe 503 away from the water inlet pipe 502 is connected to the first connecting pipe 504 via a second connecting pipe 504. The three connecting pipes 505 are connected. The third connecting pipe 505 is connected to the fifth connecting pipe 507 through the fourth connecting pipe 506. The fifth connecting pipe 507 is connected to the water outlet pipe 509 through the sixth connecting pipe 508. The first connecting pipe 503, the third connecting pipe 505 and the fifth connecting pipe 507 are all connected to the inside of the water-cooled roller assembly 14. This structure uses the water pump 501 to drive the cooling water to circulate in the multi-stage pipes and inside the roller, thereby removing the heat from the roller surface and rapidly cooling and shaping the composite material that passes through it.

[0032] Meanwhile, the adjustment assembly 6 includes a second fixed plate 604 fixedly connected to the end of the fixed bracket 15, a slide rail 606 fixedly connected to the side wall of the second fixed plate 604, a threaded rod 602 rotatably connected to the side wall of the second fixed plate 604, and a moving block 605 threadedly connected to the outer wall of the threaded rod 602. The other side of the moving block 605 is slidably connected to the surface of the slide rail 606. The adjustment assembly 6 also includes a third fixed plate 608, a support block 609 fixedly connected to the top of the third fixed plate 608, a take-up roller 610 rotatably connected between the support blocks 609, and a limiting ring 607 slidably sleeved on the outer wall of the take-up roller 610. The moving block 605 is fixedly connected to the limiting ring 607. This structure drives the moving block 605 to move linearly along the slide rail 606 by rotating the threaded rod 602, thereby driving the limiting ring 607 to move laterally on the take-up roller 610, so as to realize the take-up limiting adjustment of materials of different widths.

[0033] In a preferred embodiment, to facilitate manual operation of the adjustment component 6, the adjustment component 6 also includes a handle 601 fixedly connected to the end of the threaded rod 602. By rotating the handle 601, the threaded rod 602 can be rotated. In order to prevent the moving block 605 from disengaging from its stroke during adjustment, a limit block 603 is also fixedly connected to the side of the second fixed plate 604. The limit block 603 is located on the moving path of the moving block 605 and plays a blocking and limiting role.

[0034] As another preferred embodiment, in order to improve the stability and guiding accuracy of the moving block 605 during movement, a groove is provided on the surface of the slide rail 606, and part of the structure of the moving block 605 is slidably engaged in the groove. The groove structure can restrict the rotation of the moving block 605 and ensure that it runs smoothly along a straight line.

[0035] As another preferred embodiment, in order to ensure the installation stability of the winding roller 610, the support block 609 is disposed at both ends of the winding roller 610, and the winding roller 610 is fixed above the third fixing plate 608 by the support blocks 609 at both ends, thereby ensuring the rotational accuracy during the winding process.

[0036] As another preferred embodiment, in order to provide a smooth material transition between the cooling process and the winding process, the device also includes a conveyor roller 13 rotatably connected to the end of the fixed bracket 15. The conveyor roller 13 is located on the conveying path between the water-cooled roller group 14 and the winding roller 610, and is used to guide the cooled finished material smoothly into the winding area.

[0037] In another preferred embodiment, in order to smoothly transport the compounded material to the cooling area, the device further includes a third roller group 11 rotatably connected to the inner wall of the fixed bracket 15. The third roller group 11 is located on the conveying path between the first extrusion shaft 9 and the water-cooled roller group 14.

[0038] Working principle: When the device starts working, the first discharge roll 1 and the second discharge roll 2 rotate and release two different substrate rolls respectively. The first roller group 7 and the second roller group 8 guide the released substrates to the processing area inside the fixed bracket 15 respectively. When the substrates reach the glue coating station, the hot melt glue machine 3 heats the internal glue to a molten state. Then the glue pump 4 starts to transport the molten hot melt glue to the predetermined glue coating position and coats it on the surface of one of the substrates. The glued substrate and the other substrate are gradually bonded together under the guidance of the first roller group 7 and the second roller group 8. Then the first extrusion shaft 9 and the second extrusion shaft 10 apply opposing pressure to the bonded substrates, so that the two substrates are tightly bonded together under the action of hot melt glue. The bonded material is then conveyed to the rear through the third roller group 11.

[0039] At this time, the water cooling component 5 starts working. The water pump 501 introduces cooling water through the water inlet pipe 502. The cooling water enters the interior of the first fixed plate 12 and flows through the first connecting pipe 503, the second connecting pipe 504 and the third connecting pipe 505 in sequence. Then it flows through the fourth connecting pipe 506 into the fifth connecting pipe 507, and finally flows out through the sixth connecting pipe 508 and the water outlet pipe 509. During this process, the cooling water continuously circulates inside the water-cooled roller assembly 14. When the high-temperature composite material passes over the surface of the water-cooled roller assembly 14, the circulating cooling water in the roller quickly removes the heat from the material, so that the hot melt adhesive layer can be quickly solidified and shaped, preventing the material from sticking or deforming during subsequent conveying, and ensuring the stability of the composite structure.

[0040] After cooling and shaping, the finished material is smoothly guided to the winding area by the conveyor roller 13. Before or during the winding operation, the screw rod 602 is rotated by manually turning the handle 601 of the adjusting component 6. The screw rod 602 drives the moving block 605, which is fitted on its outer wall, to move linearly. At the same time, the other side of the moving block 605 slides along the groove inside the slide rail 606. This groove structure effectively prevents the moving block 605 from rotating with the screw rod 602 and ensures smooth movement. The limiting block 603 on the side of the second fixed plate 604 prevents the moving block 605 from going out of its stroke. The movement of the moving block 605 synchronously drives the upper limiting ring 607 to move laterally, thereby adjusting the distance between the two limiting rings 607 to accommodate materials of different widths. The two ends of the winding roller 610 are stably supported above the third fixed plate 608 by the support blocks 609. Finally, the finished roll is neatly wound up on the outer wall of the winding roller 610 under the constraint of the limiting ring 607.
