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 existing technologies, some improved solutions employ adhesive-coating equipment, using glue to bond pearl cotton. The design of the glue roller and glue box is crucial in determining the glue application accuracy and process flexibility. In existing technologies, the glue box is typically fixed above or below the glue roller, using the rotation of the roller to transfer the glue to the surface of the lower or upper material. However, this structure suffers from the following technical bottlenecks: (i) The glue box physically obstructs the upper or lower area of ​​the glue roller (i.e., a "limiting effect"), causing the glue roller to only apply glue to the lower material or only one side of the lower material. It cannot selectively apply glue to the surface of the upper or lower material on the same machine according to process requirements, severely restricting the diversity of bonding path design. (ii) The glue application mechanism uses a fixed design, allowing only unidirectional glue application to the upper or lower substrate. It cannot selectively adjust the position of the glue application mechanism or adapt the glue application path according to material characteristics and joint structure. In addition to the problems mentioned above, the feeding mechanism in the existing technology only has one feeding position. When the material at the feeding position is depleted, a break occurs, which seriously reduces the processing efficiency.

[0004] Therefore, there is an urgent need to develop a new type of pearl cotton bonding equipment that can ensure bonding strength while enabling selective gluing strategies, thus achieving versatility and improving processing efficiency. Utility Model Content

[0041] 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.

[0042] The following is in conjunction with the appendix Figure 1 To be continued Figure 9The present invention will be described in detail with specific embodiments.

[0043] like Figures 1 to 9 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. A feeding mechanism 5 is disposed on the side of the feeding mechanism 2. The feeding mechanism 2 is used to transport the lower material, and the feeding mechanism 5 is used to provide the upper material. The picking mechanism 4 reciprocates between the feeding mechanism 2 and the feeding mechanism 5. The picking mechanism 2 mainly transports the upper material and glues 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.

[0044] The feeding mechanism 2 includes a feeding platform 21 and a feeding drive assembly 22 connected to the feeding platform 21. The feeding drive assembly 22 drives the feeding platform 21 to move horizontally in a first direction. The feeding platform 21 is on which the material is placed. This application does not limit the specific structure of the feeding drive assembly 22, as long as it can drive the feeding platform 21 to move horizontally in the first direction. For example, the feeding drive assembly 22 can be a gear and rack drive assembly, a screw drive assembly, a conveyor belt drive assembly, etc., but is not limited to these. The gluing mechanism 3 includes a horizontal moving base 31 that moves in the first direction, a lifting assembly 32 disposed on the horizontal moving base 31, and a gluing assembly 33 installed on the lifting end of the lifting assembly 32. The gluing assembly 33 is located above the feeding platform 21. The gluing assembly 33 includes a rotatably disposed gluing roller 331. Both the upper and lower curved surfaces of roller 331 are adhesive-coating surfaces. Understandably, the adhesive roller 331 rotates continuously during operation. The upper curved surface described here refers to the upper curved surface of the adhesive roller 331 during rotation, while the lower curved surface refers to the lower curved surface of the adhesive roller 331 during rotation. The upper curved surface can be used to apply adhesive to the upper material on the feeding mechanism 4, while the lower curved surface can be used to apply adhesive to the lower material on the feeding platform 21. Through the above design, the adhesive-coating component 33 of this application can move along the first direction and also perform lifting and lowering movements. Furthermore, by designing both the upper and lower curved surfaces of the adhesive roller 331 as adhesive-coating surfaces, the limitation of traditional single-sided adhesive coating is broken. This allows this application to select adhesive coating for both the lower and upper materials, realizing the selection of adhesive coating strategies based on material characteristics and greatly expanding the adaptability of the process.

[0045] The 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 upper part of the feeding platform 21. After the gluing mechanism 3 applies glue to the lower or upper material, the material handling mechanism 4 bonds 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 achieved without human intervention, which significantly improves the bonding efficiency of packaging materials and reduces the intensity of manual operation.

[0046] It is important to note that the gluing machine of this application can not only achieve the bonding of two layers of materials, but also the bonding of multiple layers of materials. When applied to the bonding of multiple layers of materials, the gluing roller 331 can apply glue to the lower surface of the upper material transported by the feeding mechanism 4. Each time the feeding mechanism 4 picks up an upper material, the gluing roller 331 applies glue to it once, thereby completing the bonding of multiple layers of materials.

[0047] For details, please refer to Figure 1 and Figure 2 The feeding mechanism 5 is located at the end of the conveying direction of the feeding platform 21. The feeding mechanism 5 includes a feeding rack 51 and a feeding platform 52 set on the feeding rack 51. A slide rail 53 extending in the second direction is provided on the frame 1 or the ground. The feeding rack 51 is slidably set on the slide rail 53. The feeding platform 52 is provided with at least two feeding positions arranged side by side. Each feeding position is stacked with the feeding material. This application places the feeding mechanism 5 at the end of the loading platform 21, forming a seamless material flow layout. The slide rail 53 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 at least two feeding positions on the feeding platform 52, after the picking mechanism 4 has removed all the material from one feeding position, it pushes the feeding rack 51 along the slide rail 53, moving the second feeding position to the end of the conveying direction of the loading platform 21. This achieves continuous feeding, ensuring uninterrupted machine production and improving work efficiency. It should be noted that the number of feeding positions in this application can be expanded according to needs to meet the requirements of large-volume orders or multi-variety mixed-line production. Simultaneously, the design of this application needs to consider the relationship between the extension direction of the slide rail 53 and the feeding positions, ensuring that the feeding mechanism 5 moves along the slide rail 53 so that multiple feeding positions are sequentially located below the loading position of the picking mechanism 4.

[0048] In a preferred embodiment, the second direction is perpendicular to the first direction. For example, the first direction is the X-axis and the second direction is the Y-axis. At least two feeding positions on the feeding platform 51 are arranged side by side along the second direction, meaning the slide rail 53 also extends along the Y-axis. This perpendicular design of the first and second directions allows the feeding mechanism 5 to slide freely along the second direction, enabling free switching of feeding positions. The feeding mechanism 5 and the loading mechanism 2 are vertically arranged, making the overall layout more rational and significantly improving the space utilization of the equipment. For example, the feeding platform 51 has two feeding positions arranged side by side. The first feeding position is pushed to the end of the loading mechanism 2 to provide material to the picking mechanism 4. When the material on the first feeding position is depleted, the feeding rack 51 can be pulled or pushed from either end of the second direction to push the second feeding position to the end of the loading mechanism 2 to continue providing material to the picking mechanism 4. Simultaneously, during the feeding process at the second feeding position, the operator can continue to stack the processed material onto the first feeding position, thus achieving non-stop feeding and significantly improving processing efficiency. Of course, in other embodiments, the first direction and the second direction may also be intersecting, as long as the function of this application can be achieved. It should be noted that the lower material on the loading platform 21 and the upper material on one of the feeding positions of 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.

[0049] Specifically, a lifting mechanism 54 is provided on each of the opposite sides of the feeding platform 52. The lifting end of the lifting mechanism 54 is provided with a support plate 541. The two support plates 541 are located below the feeding platform 52, and can contact the lower surface of the feeding platform 52, thus moving the feeding platform 52 up and down on the feeding rack 51. It is known 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 material picking process, resulting in excessive lifting stroke of the picking mechanism 4. This application addresses this by setting up lifting mechanisms 54 to drive the feeding platform 52 to move up and down. After the picking mechanism 4 removes the top layer of material, the lifting mechanism 54 raises the feeding platform 52 by the thickness of the top material, ensuring 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 mechanisms dynamically compensate for changes in the stacking height of the feeding platform 52, ensuring that the picking position of the picking mechanism 4 remains constant each time it picks up material. The purpose of setting up the lifting mechanism 54 in this application is to compensate for the lifting stroke of the material handling mechanism 4, shorten the material handling time of the material handling mechanism 4, and thus improve the processing efficiency of the machine.

[0050] Preferred options, please refer to Figure 2The lifting mechanism 54 of this application includes a bearing fixing plate 542, a motor fixing frame 543, and a fourth motor 544 mounted on the motor fixing frame 543. The motor fixing frame 543 is mounted on the bearing fixing plate 542. The output shaft of the fourth motor 544 is connected to a reducer 545. The output shaft of the reducer 545 is connected to a third synchronous pulley 546. Two idler pulleys 547 are rotatably mounted on the bearing fixing plate 542 near the third synchronous pulley 546, and two spaced fourth synchronous pulleys 548 are rotatably mounted away from the third synchronous pulley 546. A second synchronous belt is fitted on the third synchronous pulley 546, the two idler pulleys 547, and the two fourth synchronous pulleys 548. A first screw 549 is rotatably connected to the two fourth synchronous pulleys 548. A first nut 550 is fitted on the first screw 549. A support plate 541 is fixedly connected to the two first nuts 550. The rotation of the first screw 549 drives the first nuts 550 to move up and down, thereby driving the support plate 541 to move up and down, realizing the lifting function of the feeding platform 52. In order to achieve stable rotation of the first screw 549, both ends of the first screw 549 are connected to the corresponding bearing fixing plates through bearings.

[0051] Specifically, the feeding rack 51 includes two vertical frames 511 arranged opposite each other, 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.

[0052] For details, please refer to Figure 1 and Figure 5The upper part of the frame 1 is provided with a transverse slide rail 11 and a transverse rack 12 extending along the first direction. The material picking mechanism 4 includes a slide plate 41 slidably connected to the transverse slide rail 11 and a material picking component disposed on the slide plate 41 that moves up and down. One end of the transverse slide rail 11 and the transverse rack 12 extends above the feeding mechanism 2 and the other end extends above the feeding mechanism 5. A first motor 42 is also provided on the slide plate 41. The output shaft of the first motor 42 passes through the slide plate 41 and is connected to a second gear 43. The second gear 43 meshes with the transverse rack 12, thereby driving the material picking mechanism 4 to reciprocate along the first direction through the first motor 42. The material handling assembly includes a lifting plate 44, a material handling component 45 disposed at the lower end of the lifting plate 44, and a drive assembly 46 for driving the lifting plate 44 to move up and down. The drive assembly 46 includes a second motor 461 fixed to the upper end of the lifting plate 44, a drive wheel 462 mounted on the output shaft of the second motor 461, a driven wheel 463 cooperating with the drive wheel 462, a belt 464 mounted on the drive wheel 462 and the driven wheel 463, and a second screw 468 connected to the driven wheel 463. A second nut 467 is fixed on the side of the slide plate 41 opposite to the lifting plate 44, and the second nut 467 is connected to the second screw 468 in a transmission connection. The output shaft of the second motor 461 rotates, driving the drive wheel 462 to rotate. The drive wheel 462 drives the driven wheel 463 to rotate via the belt 464. The driven wheel 463 drives the second screw 468 to rotate. The second screw 468 cooperates with the second nut 467 to realize the up and down movement of the lifting plate 44. The lifting plate 44 drives the picking component 45 to move up and down. The picking component 45 in this application can be a picking suction cup or a picking needle plate, but is not limited to these.

[0053] In a specific embodiment, see Figure 6 , Figure 8 and Figure 9 The loading drive assembly 22 includes a third motor 221 fixed below the loading platform 21, a first synchronous pulley 222 connected to the third motor 221, a second synchronous pulley 223 cooperating with the first synchronous pulley 222, and a first synchronous belt 224. The lower surface of the loading platform 21 is fixed to the first synchronous belt 224 via a connector 225. A guide rail 227 located below the loading platform 21 and extending along a first direction is also provided on the frame 1. A guide slider 226 cooperating with the guide rail 227 is fixed to the lower surface of the loading platform 21. The third motor 221 drives the first synchronous belt 224 to rotate around the first synchronous pulley 222 and the second synchronous pulley 223, and drives the loading platform 21 to move along the first direction through the first synchronous belt 224. At the same time, the cooperation of the guide rail 227 and the guide slider 226 realizes a more stable reciprocating movement of the loading platform 21.

[0054] Preferably, the feeding platform 21 is provided with a first side positioning strip 211 and a second side positioning strip 212 that are perpendicular to each other, and the side of the lower material abuts and is positioned with the first side positioning strip 211 and the second side positioning strip 212 respectively.

[0055] For specific embodiments, see [link to relevant documentation]. Figure 3 and Figure 4 In this application, the gluing mechanism 3 reciprocates along a first direction via a horizontal moving component 34, which is located below the feeding mechanism 2. This application does not limit the specific structure of the horizontal moving component 34; those skilled in the art can design it according to actual conditions. In an optional embodiment, the horizontal moving component 34 includes a power unit 341, a drive shaft 342 connected to the power unit 341, and a horizontal moving base 31 mounted on the drive shaft 342 via a bearing seat. A first gear 343 is fixed to each end of the drive shaft 342, and a rack 344 corresponding to the first gear 343 is fixed on the frame 1. The extension direction of the rack 344 is consistent with the first direction. It should be noted that the power unit 341 in this application has a dual-output structure. Through the first gears 343 at both ends of the drive shaft 342, the horizontal moving base 31 reciprocates horizontally along the extension direction of the rack 344. The lifting component 32 is mounted on the horizontal moving base 31. In this embodiment of the application, a slider 345 is fixed on the lower surface of the horizontal moving base 31, and a linear guide rail 346 is provided on the frame 1. The slider 345 is slidably connected to the linear guide rail 346. The slider 345 and the linear guide rail 346 are configured to provide guidance for the movement of the horizontal moving base 31 and make it reciprocate horizontally more stably.

[0056] Specifically, the gluing assembly 33 is mounted on the horizontally movable base 31 via a lifting assembly 32. The lifting assembly 32 includes a third nut 321 rotatably mounted on the horizontally movable base 31, a third screw 322 screwed to the third nut 321, and a first drive assembly 323 that drives the third nut 321 to rotate. The lower end of the third screw 322 passes through the horizontally movable base 31 and extends downwards, while the upper end of the third screw 322 is connected to the gluing assembly 33. There are multiple third nuts 321, which are circumferentially mounted on the horizontally movable base 31. Each third nut 321 is fixedly fitted with a fifth synchronous wheel 324, and a third synchronous belt 325 is fitted onto the multiple fifth synchronous wheels 324. The first drive assembly 323 drives the third synchronous belt 325 to rotate. It can be understood that the function of the first drive assembly 323 in this application is to drive the third nut 321 to rotate. Therefore, the specific structure of the first drive assembly 323 is not limited, as long as it can achieve the rotation of the third nut 321, it falls within the protection scope of this application.

[0057] In a preferred embodiment, at least one tensioning pulley 326 is also provided on the outer side of the third synchronous belt 325. It is understood that the tension of the third synchronous belt 325 will decrease during prolonged use, causing the belt to loosen. This application addresses this by providing a movable tensioning pulley 326, which can be adjusted at any time according to the usage of the synchronous belt, ensuring the synchronous rotation of all third nuts 321.

[0058] In some embodiments, the lifting end of the lifting assembly 32 is fixed with two spaced-apart mounting plates 332, and the gluing assembly 33 is mounted on the lower end surface of the mounting plates 332. The gluing assembly 33 also includes a glue storage tank 333 disposed on the side of the gluing roller 331, with the opening end of the glue storage tank 333 facing upward. A heating assembly is disposed below the glue storage tank 333 to heat the glue in the glue storage tank 333. The bottom of the glue storage tank 333 has an opening facing the discharge gap of the gluing roller 331. After the glue flows out from the discharge gap, it adheres to the gluing roller 331, and then the glue is coated onto the upper packaging material by the gluing roller 331. In this application, the upper curved surface of the gluing roller 331 is exposed in the upper space, allowing it to contact the upper material on the feeding mechanism 4, while the lower curved surface is exposed in the lower space, allowing it to contact the lower material on the feeding mechanism 2. The glue storage tank 333 is located near the feed end of the glue conveying roller 331. A separation component is provided on the side of the glue conveying roller 331 away from the feed end. The separation component includes a plurality of arc-shaped separation members 334 spaced apart along the axial direction of the glue conveying roller 331. The arc-shaped separation members 334 are used to prevent the lower material from tilting up and falling off the feeding platform 21.

[0059] In some embodiments, the glue roller 331 is a hollow shaft, and a heating rod is installed inside the hollow shaft. The heating rod is used to reheat the glue on the glue roller 331 to ensure that the glue can be smoothly coated onto the lower or upper material.

[0060] It is worth noting that the pressing position of the material-grabbing mechanism 4 in this application is located on the feeding mechanism 2. Therefore, regardless of whether the adhesive is applied to the upper surface of the lower material or the lower surface of the upper material, the adhesive application component 33 needs to be moved to a suitable position to avoid affecting the pressing. For example, when the adhesive roller 331 applies adhesive to the upper surface of the lower material, the adhesive application component 33 moves to a position close to the lower material under the action of the horizontal moving component 34. When the lower material passes through the adhesive roller 331, it contacts the adhesive roller 331 until it passes through the adhesive roller 331 to complete the adhesive application. The lower material that has been coated continues to move forward to a certain position, and then the material-grabbing mechanism 4 grabs the upper material and adheres it to the lower material. When the adhesive roller 331 applies adhesive to the lower surface of the upper material, the adhesive application component 33 moves to a position away from the lower material under the action of the horizontal moving component 34. When the material-grabbing mechanism 4 grabs the upper material and passes through the adhesive roller 331, it applies adhesive to the lower surface of the upper material. After the adhesive application is completed, it continues to move above the lower material and adheres the upper material to the lower material.

[0061] In the preferred embodiment, see Figure 1 and Figure 7 A cotton pressing machine 6 is also provided on the side of the feeding mechanism 5 away from the feeding mechanism 2. The cotton pressing machine 6 includes an upper conveyor belt 61, a lower conveyor belt 62, and a lifting drive assembly 63. The length of the lower conveyor belt 62 is longer than the length of the upper conveyor belt 61, and one end of the lower conveyor belt 62 extends to the bottom of the picking mechanism 4 inside the frame 1, while the other end is located outside the frame 1. The upper conveyor belt 61 is located above the lower conveyor belt 62 outside the frame 1. The lifting drive assembly 63 is used to drive the upper conveyor belt 61 to move 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 through the belt drive assembly 64. After the picking mechanism 4 places the pressed packaging material on the lower conveyor belt 62, the lower conveyor belt 62 drives the bonded packaging material to move outward to the bottom of the upper conveyor belt 61. Then, the lifting drive assembly 63 drives the upper conveyor belt 61 to move downward, clamping the packaging material between the upper conveyor belt 61 and the lower conveyor belt 62, and moving outward synchronously. This application utilizes the clamping action of the upper conveyor belt 61 and the lower conveyor belt 62 to enable the lower and upper materials to bond quickly, thereby shortening the curing time of the adhesive.
