Description

Technical Field

[0001] This utility model belongs to the technical field of packaging material bonding equipment, specifically a gluing machine. Background Technology

[0002] With the rapid development of modern industry, EPE (Expanded Polyethylene) foam, as a lightweight, highly cushioning, and corrosion-resistant new environmentally friendly packaging material, has been widely used in the transportation and protection of high-value products such as electronic products, precision instruments, and handicrafts. Traditional EPE foam bonding processes mainly rely on hot-melt bonding technology, which involves melting and pressing a single layer of EPE foam at high temperatures using an aluminum heating plate, utilizing the material's own melting properties to achieve adhesion. However, this technology has significant drawbacks: high-temperature treatment easily damages the bubble structure on the surface of the EPE foam, reducing the material's cushioning performance; controlling the melting temperature and pressing time is difficult, easily leading to weak adhesion or excessive carbonization; and the process is only suitable for rough processing scenarios with low requirements for surface smoothness.

[0003] In the existing technology, some improved solutions use glue-coating equipment to bond pearl cotton through glue coating. However, the existing pearl cotton has various thickness specifications, but the traditional glue-coating roller and conveyor platform cannot flexibly match the thickness changes of pearl cotton, resulting in thin materials being deformed due to excessive pressure, while thick materials suffer from missed coating or uneven glue coating due to excessive gaps.

[0004] Therefore, there is an urgent need to develop a new type of pearl cotton bonding equipment that can ensure bonding strength while enabling the application of adhesive to pearl cotton of different thicknesses and specifications, and also achieve versatility of the equipment.

[0011] A feeding mechanism is located on the moving path of the picking mechanism and is used to provide material to the picking mechanism.

[0012] The material picking mechanism is mounted on the frame and reciprocates between the bonding end and the feeding mechanism. The material picking mechanism is used to transfer the upper material on the feeding mechanism to the top of the bonding end.

[0017] Furthermore, the lifting mechanism also includes a guide sleeve fixed on the mounting plate, a guide rod installed inside the guide sleeve, the lower end of the guide rod being located below the mounting plate, and the upper end of the guide rod being connected to the gluing mechanism.

[0018] Furthermore, the feeding mechanism also includes a conveying platform, which moves horizontally in a first direction driven by the feeding drive assembly.

[0019] Furthermore, the feeding mechanism is located at the end of the conveying direction of the feeding mechanism, and the feeding mechanism includes a feeding frame, a feeding platform disposed on the feeding frame, and a lifting drive assembly for driving the feeding platform to rise and fall.

[0020] Furthermore, the feeding mechanism also includes a limiting component, which includes two sets of oppositely arranged limiting plates and a manual wheel assembly for driving the limiting plates to move relative to or away from each other.

[0021] The manual wheel assembly includes a limiting screw, a limiting nut, and a rotating handwheel. One end of the limiting screw passes through the side plate of the feeding rack and is connected to the rotating handwheel. Two limiting nuts are fitted on each limiting screw, and the two limiting nuts are respectively connected to two opposite limiting plates. The position of the limiting plates can be adjusted by manually rotating the rotating handwheel.

[0022] Furthermore, a slide rail extending along the second direction is provided on the frame or the ground, and there are two feeding racks arranged side by side along the second direction, with both feeding racks slidably mounted on the slide rail.

[0023] Furthermore, a lifting drive assembly is provided on each side of the sliding direction of the feeding rack.

[0024] Furthermore, the feeding platform includes at least two support bars slidably connected to the feeding rack along a first direction; or the feeding platform includes at least two support bars slidably connected to the feeding rack along a second direction.

[0025] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0026] (1) The gluing and bonding machine of this utility model includes a feeding mechanism, a gluing mechanism, a material taking mechanism and a feeding mechanism. The gluing mechanism is mounted on the frame and can be moved up and down by a lifting mechanism. The gluing mechanism is located between the feeding end and the bonding end. The gluing mechanism includes a rotatable gluing roller, and the lower curved surface of the gluing roller is the gluing surface. The lifting mechanism is fixed on the frame. This realizes the adjustment of the height position of the gluing roller. At the same time, the lower curved surface of the gluing roller is designed as the gluing surface, so that this application can glu different thicknesses of pearl cotton and the equipment is versatile.

This enables the feeding of pearl cotton of different sizes and avoids the problem of poor bonding quality caused by inaccurate positioning during the feeding process. At the same time, by setting two feeding racks that slide along the second direction, when the picking mechanism has taken all the material from one of the feeding racks, it pushes the feeding rack so that the second feeding rack is located at the end of the conveying direction of the feeding mechanism, thereby improving the feeding efficiency.

[0042] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0043] The following is in conjunction with the appendix Figure 1 To be continued Figure 7 The present invention will be described in detail with specific embodiments.

[0044] like Figures 1 to 7 As shown, this utility model provides a gluing machine, including a frame 1 and a feeding mechanism 2, a gluing mechanism 3, and a picking mechanism 4 disposed on the frame 1. The feeding mechanism 2 is used to convey the lower material. A feeding mechanism 5 is disposed on the moving path of the picking mechanism 4. The feeding mechanism 5 is used to provide the upper material to the picking mechanism 4. The picking mechanism 4 reciprocates between the feeding mechanism 2 and the feeding mechanism 5. The main function of the picking mechanism 4 is to convey the upper material and glue the upper material to the lower material. It can be understood that both the lower material and the upper material are packaging materials. Here, for the convenience of describing the way the two pieces of packaging materials are glued together, the lower material and the upper material are used respectively for easy understanding.

[0045] See Figure 1The feeding mechanism 2 is mounted on the frame 1. The feeding mechanism 2 includes a feeding end 22 and an adhesive end 23. The feeding end 22 is located outside the frame 1, and the adhesive end 23 is located inside the frame 1. The feeding mechanism 2 also includes a conveying platform 21. The initial position of the conveying platform 21 is located at the feeding end 22. The worker first places the unloaded material on the conveying platform 21 at the feeding end 22. The conveying platform 21 moves horizontally back and forth between the feeding end 22 and the adhesive end 23 along the first direction driven by the feeding drive assembly. Before moving to the adhesive end 23, the conveying platform 21 passes under the glue roller 34, and the glue roller 34 contacts the unloaded material to apply glue to its upper surface. This application does not limit the specific structure of the feeding drive assembly, as long as it can drive the conveying platform 21 to move horizontally along the first direction. For example, the feeding drive assembly can be a gear and rack drive assembly, a screw drive assembly, a conveyor belt drive assembly, or other drive assemblies in the prior art, but is not limited to these. The gluing mechanism 3 is vertically movable on the frame 1 via the lifting mechanism 31, and is located between the feeding end 22 and the bonding end 23. The gluing mechanism 3 includes a rotatably mounted gluing roller 34, the lower curved surface of which is the gluing surface. The lifting mechanism 31 is fixed to the frame 1. Understandably, the gluing roller 34 rotates during operation. The lower curved surface described here refers to the curved surface located at the bottom of the gluing roller 34 during rotation. The lower curved surface can be used to apply glue to the material on the conveying platform 21. In this application, the gluing mechanism 3 is vertically movable via the lifting mechanism 31. The lower moving part is set on the frame 1 to achieve precise control of the distance and contact pressure between the glue roller 34 and the lower material. This is crucial for controlling the thickness and uniformity of the glue coating and directly affects the bonding quality. At the same time, the lifting function of the glue coating mechanism 3 allows the equipment to adapt to lower materials of different thicknesses, ensuring that the glue coating surface can always effectively contact the lower material and apply glue. This application cleverly sets the glue coating mechanism 3 between the feeding end 22 and the bonding end 23, so that when the lower material moves from the feeding end 22 to the bonding end 23, it can immediately receive glue treatment, making the process compact and efficient.

[0046] Preferably, the conveying platform 21 is provided with a first side positioning bar and a second side positioning bar (not shown in the figure) that are perpendicular to each other, and the side edge of the lower material abuts and is positioned with the first side positioning bar and the second side positioning bar respectively.

[0047] See Figure 1 and Figure 4The material handling mechanism 4 is mounted on the frame 1 and moves on the frame 1. The material handling mechanism 4 is used to transfer the upper material from the feeding mechanism 5 to the top of the conveying platform 21. After the lower material is glued by the gluing mechanism 3, the material handling mechanism 4 glues the upper and lower materials together. Through the coordinated work of the feeding mechanism 2, the feeding mechanism 5, the material handling mechanism 4 and the gluing mechanism 3, the automatic conveying, positioning and bonding of the lower and upper materials are realized without human intervention, which significantly improves the bonding efficiency of packaging materials and reduces the intensity of manual operation.

[0048] For details, please refer to Figure 3 In one embodiment, the lifting mechanism 31 includes worm gear screw lifting structures 311 spaced apart on both sides of the conveying platform 21, a horizontal transmission shaft 312 connected to the two worm gear screw lifting structures 311, and a drive assembly for driving the horizontal transmission shaft 312 to rotate. The drive assembly includes a first motor 313, a first gear 314 connected to the output shaft of the first motor 313, and a second gear 315 meshing with the first gear 314. The second gear 315 is fixedly mounted on the horizontal transmission shaft 312, thereby driving the horizontal transmission shaft 312 to rotate. The lifting end of the worm gear screw lifting structure 311 is connected to a limit block 316. At least two lifting rods 317 are connected to the limit block 316. The upper end of the lifting rod 317 is connected to the gluing mechanism 3. The horizontal transmission shaft 312 rotates to drive the lifting rod 317 to rise and fall, thereby driving the gluing mechanism 3 to achieve lifting and falling motion. Preferably, a linear bearing is also mounted on the lifting rod 317. The linear bearing is fixed on the frame 1, thereby enabling the lifting rod 317 to perform stable lifting and falling motion.

[0049] In another embodiment, see Figure 2The lifting mechanism 31 includes a mounting plate 321 fixed on the frame 1, a lead screw seat 322 arranged around the mounting plate 321, and a lead screw 323 threadedly connected to the lead screw seat 322. The upper end of the lead screw 323 is connected to the glue-applying mechanism 3. The lead screw seat 322 is rotatably mounted on the mounting plate 321 through a transmission assembly. The transmission assembly includes a second motor 324 fixed at the lower end of the mounting plate 321 and a drive synchronous pulley 325 connected to the output end of the second motor 324. Each lead screw seat 322 is fitted with a driven synchronous pulley 326. The drive synchronous pulley 325 is connected to the driven synchronous pulley 326 through a synchronous belt 327. In order to further ensure the tension of the belt, a tensioning pulley 328 is also provided on the mounting plate 321. In a preferred embodiment, the lifting mechanism 31 further includes a guide sleeve 329 fixed on the mounting plate 321. A guide rod 330 is installed inside the guide sleeve 329. The lower end of the guide rod 330 is located below the mounting plate 321, and the upper end of the guide rod 330 is connected to the gluing mechanism 3. The second motor 324 drives the active synchronous wheel 325 to rotate. The active synchronous wheel 325 drives the driven synchronous wheel 326 to rotate via the synchronous belt 327. The driven synchronous wheel 326 drives the lead screw seat 322 to rotate synchronously, thereby realizing the up and down movement of the lead screw 323. Of course, in other embodiments, the lifting mechanism 31 can also be implemented using other structures, as long as they can achieve the purpose of lifting the gluing mechanism 3, all of which fall within the protection scope of this application.

[0050] For details, please refer to Figure 1 See Figure 5 and Figure 6The feeding mechanism 5 is located at the end of the conveying direction of the feeding mechanism 2. The feeding mechanism 5 includes a feeding frame 51, a feeding platform 52 set on the feeding frame 51, and a lifting drive assembly 53 for driving the feeding platform 52 to rise and fall. A slide rail (not shown in the figure) extending along the second direction is provided on the frame 1 or the ground. The feeding frame 51 is slidably set on the slide rail. At least two feeding platforms 52 arranged side by side along the second direction are provided on the feeding frame 51. The feeding platforms 52 are all stacked with the material. This application places the feeding mechanism 5 at the end of the loading mechanism 2, forming a seamless material flow layout. The slide rail extending in the second direction slides and engages with the feeding rack 51, allowing for seamless connection with the conveying rhythm of the loading mechanism 2. This enables synchronized and continuous supply of materials, eliminating waiting time between processes. Furthermore, by setting two parallel feeding platforms 52, after the picking mechanism 4 has removed all the material from one feeding platform 52, it pushes the feeding rack 51 along the slide rail 53, moving the second feeding platform 52 to the end of the conveying direction of the loading mechanism 2. This achieves continuous feeding, ensuring uninterrupted machine production and improving work efficiency. It should be noted that the number of feeding platforms 52 in this application can be expanded according to requirements to meet the needs of large-volume orders or multi-variety mixed-line production. Simultaneously, the design of this application needs to consider the relationship between the slide rail extension direction and the feeding rack, ensuring that the feeding mechanism 5 moves along the slide rail so that multiple feeding racks 51 are sequentially located below the loading position of the picking mechanism 4. It should be further explained that the feeding platform 52 of this application can also be set one-to-one with the feeding rack 51. When the material on the feeding platform 52 of one of the feeding racks 51 is taken away, the feeding rack 51 is pulled away from the end of the feeding mechanism 2, and at the same time the other feeding rack 51 is moved to the end of the feeding mechanism 2.

[0051] In a preferred embodiment, the second direction is perpendicular to the first direction. For example, the first direction is the feeding direction of the feeding mechanism 2, and the second direction is perpendicular to the feeding direction. The two feeding platforms 52 are arranged side by side along the second direction. This perpendicular design of the first and second directions allows the feeding mechanism 5 to slide freely along the second direction, enabling free switching between feeding platforms 52. The perpendicular arrangement of the feeding mechanism 5 and the feeding mechanism 2 makes the overall layout more rational and significantly improves the space utilization of the equipment. For example, one feeding platform 52 is first pushed to the end of the feeding mechanism 2 to provide material to the picking mechanism 4. When the material on the feeding platform 52 is depleted, the feeding rack 51 can be pulled or pushed from either end of the second direction to push the second feeding platform 52 to the end of the feeding mechanism 2 to continue providing material to the picking mechanism 4. Simultaneously, during the feeding process on the second feeding platform, the operator can continue to stack the processed material onto the first feeding platform, thereby achieving continuous feeding and significantly improving processing efficiency. Of course, in other embodiments, the first direction and the second direction may also be arranged to intersect, as long as the function of this application can be achieved. It should be noted that the lower material on the conveying platform 21 and the upper material on the feeding platform 52 are located on the same horizontal plane and are aligned, which allows the picking mechanism 4 to also move along the first direction, simplifying the movement path of the picking mechanism 4 and reducing equipment costs.

[0052] For details, please refer to Figure 6 The feeding mechanism 5 also includes a limiting component 54, which includes two sets of oppositely arranged limiting plates 541 and a manual wheel assembly for driving the limiting plates 541 to move relative to or away from each other. The manual wheel assembly includes a limiting screw 542, a limiting nut 543 and a rotating handwheel 544. One end of the limiting screw 542 passes through the side plate of the feeding frame 51 and is connected to the rotating handwheel 544. Two limiting nuts 543 are fitted on each limiting screw 542. The two limiting nuts 543 are respectively connected to the two opposite limiting plates 541. The position of the limiting plate 541 can be adjusted by manually rotating the rotating handwheel 544. The relative arrangement of two sets of limiting plates 541 forms an adjustable-width material channel for positioning the material according to its dimensions. During adjustment, the operator rotates the handwheel 544 to rotate the limiting screw 542. The rotation of the limiting screw 542 causes two limiting nuts 543 to move in opposite directions along the limiting screw 542, thereby causing the limiting plates 541 to move synchronously closer to or further away. This structural design allows the operator to quickly adjust the spacing between the two sets of limiting plates 541, precisely matching the width and length of the material. It is compatible with various material specifications without hardware replacement, significantly improving the equipment's versatility and reducing downtime for changeovers. Furthermore, the design of double limiting nuts 543 on a single limiting screw 542 ensures that the limiting plates 541 always move synchronously in opposite directions, avoiding offset errors caused by manual adjustment.

[0053] For details, please refer to Figure 5 A lifting drive assembly 53 is provided on each side of the sliding direction of the feeding rack 51. The lifting drive assembly 53 includes a rotatable screw 532 and a nut 533 fitted on the screw 532. A support plate 531 is fixed on the nut 533. The support plate 531 is located below the feeding platform 52 and is in contact with the lower surface of the feeding platform 52, driving the feeding platform 52 to move up and down on the feeding rack 51. It can be seen that if the feeding platform 52 is fixed on the feeding rack 51, the picking position of the picking mechanism 4 will continuously decrease during the continuous picking process, resulting in excessive lifting stroke of the picking mechanism 4. However, by setting up the lifting drive assembly 53, the feeding platform 52 is driven to move up and down. After the picking mechanism 4 picks up the uppermost material, the lifting drive assembly 53 drives the feeding platform 52 to rise by the thickness of the upper material, so that the picking position of the picking mechanism 4 does not change, thereby reducing the lifting stroke of the picking mechanism 4. In this embodiment, the dual lifting mechanism dynamically compensates for changes in the stacking height of the feeding platform 52, ensuring that the material-grabbing mechanism 4 maintains a constant picking position each time it picks up material. The purpose of providing the lifting drive assembly 53 in this application is to compensate for the lifting stroke of the material-grabbing mechanism 4, shorten the picking time of the material-grabbing mechanism 4, and thus improve the processing efficiency of the machine.

[0054] For details, please refer to Figure 6 The feeding rack 51 includes two vertical frames 511 spaced apart along a second direction. Vertical rails 512 are mounted on the vertical frames 511, and the feeding platform 52 is slidably connected to the vertical rails 512 via vertical sliders 513. The cooperation between the vertical frames 511 and the vertical rails 512 ensures more stable lifting and lowering of the feeding platform 52, preventing displacement of the material during lifting and lowering, which could affect the bonding effect.

[0055] Specifically, the feeding platform 52 includes at least two support bars 521 slidably connected to the feeding rack 51 along a first direction; or the feeding platform 52 includes at least two support bars 521 slidably connected to the feeding rack 51 along a second direction. By setting the support bars 521, interference between the plate-shaped feeding platform 52 and the limiting plate 541 is avoided. The space formed between the support bars 521 allows the limiting plate 541 to pass through, making it easier to adjust the limiting plate 541 and adapting to materials of more sizes.

[0056] For details, please refer to Figure 1 , Figure 7In some embodiments, the gluing machine further includes a pressing mechanism 6, which includes an upper conveyor belt 61, a lower conveyor belt 62, and a lifting assembly 63. The lower conveyor belt 62 is longer than the upper conveyor belt 61, with one end extending below the gluing end 23 inside the frame 1 and the other end outside the frame 1. The upper conveyor belt 61 is located above the lower conveyor belt 62 outside the frame 1. The lifting assembly 63 is used to drive the upper conveyor belt 61 closer to or away from the lower conveyor belt 62. In this embodiment, the upper conveyor belt 61 and the lower conveyor belt 62 move forward synchronously via a belt drive assembly 64. After the material handling mechanism 4 places the pressed packaging material on the lower conveyor belt 62, the lower conveyor belt 62 drives the glued packaging material to move outward to below the upper conveyor belt 61. Then, the lifting assembly 63 drives the upper conveyor belt 61 downward to clamp the packaging material between the upper conveyor belt 61 and the lower conveyor belt 62, and moves it outward synchronously. This application utilizes the clamping action of the upper conveyor belt 61 and the lower conveyor belt 62 to quickly bond the lower and upper materials together, thereby shortening the curing time of the adhesive.

[0057] The workflow of this application will be explained below using one specific example:

[0058] Before starting work, the upper material is stacked on the feeding mechanism 5, and one of the feeding platforms 52 filled with the upper material is moved to the end of the feeding mechanism 2. The initial position of the conveying platform 21 is located at the feeding end 22 outside the frame 1. The worker places the lower material on the conveying platform 21. The conveying platform 21 moves forward along the first direction to the bottom of the gluing mechanism 3 and contacts the gluing surface, gradually applying glue to the upper surface of the lower material. The lower material after applying glue continues to move forward with the conveying platform 21 to the bonding end 23.

[0059] After the material-picking mechanism 5 moves to directly above the feeding platform 52 to pick up the material, it moves backward to directly above the bonding end 23. Once the upper material on the material-picking mechanism 4 is aligned with the lower material on the bonding end 23, the material-picking mechanism 5 moves the upper material downward to contact and press it against the lower material on the bonding end 23. After pressing, the material-picking mechanism 5 lifts the bonded material to detach it from the conveying platform 21. Then, the conveying platform 21 retracts away from the bonding end 23. Finally, the material-picking mechanism 4 releases the bonded material onto the pressing mechanism 6 for further pressing.

[0060] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the substance and scope of the present invention. Various modifications made by those skilled in the art to the above embodiments after reading this specification are all within the scope of protection of the present invention.
