Description

Technical Field

[0001] This utility model relates to the field of packaging material processing technology, and in particular to an automatic gluing machine. Background Technology

[0002] Packaging materials include EPE foam, cardboard, polyethylene, polyvinyl chloride, and more. Taking EPE foam as an example, it boasts numerous advantages such as water and moisture resistance, shock absorption, sound insulation, heat insulation, excellent plasticity, high toughness, recyclability, environmental friendliness, and strong impact resistance. It also exhibits excellent chemical resistance, making it an ideal packaging material. Due to the limitations of its plasticity, most existing packaging materials require a series of tedious processing steps, a crucial one being the lamination of the packaging components. Manual gluing and lamination is time-consuming, labor-intensive, and inefficient. Existing automatic gluing machines are difficult to adapt to packaging materials of different sizes, resulting in long setup times and potential material misalignment. Utility Model Content

[0075] Preferred embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the scope of the present invention to those skilled in the art.

[0076] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0077] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0078] It should be noted that, according to Figure 1 As shown, in this embodiment of the invention, the X-axis direction intersects with the Y-axis direction. For ease of explanation, the first direction is defined as the X-axis direction, and the second direction is defined as the Y-axis direction. In this embodiment, the X-axis direction and the Y-axis direction are coplanar and relatively perpendicular, and the first direction is relatively perpendicular to the second direction. Further explanation: the term "parallel" in this application includes not only absolute parallelism but also the generally understood parallelism in engineering, such as "parallel" referring to the angle between two lines, a line and a surface, or a surface, where the angle is between □1° and 1°. Similarly, "perpendicular" also includes not only absolute perpendicularity but also the generally understood perpendicularity in engineering, such as "perpendicular" referring to the angle between two lines, a line and a surface, or a surface, where the angle is between 89° and 91°. Equal distances or equal angles include not only absolute equality but also generally understood equality in engineering, meaning there may be some error, such as a tolerance range of -1% to 1%.

[0079] Although existing automatic gluing machines have achieved automated gluing of packaging materials, the dimensions of these materials often vary in practical applications. Therefore, when using such automatic gluing machines, manual intervention is still required to neatly arrange the second workpiece placed on the support platform or adjust the transfer mechanism to correctly pick up the second workpiece. This process prolongs on-site setup time. Furthermore, the stacked second workpieces are prone to positional deviations, which may cause poor adhesion when the second workpiece is bonded to the first workpiece.

[0080] To address the aforementioned issues, this utility model provides an automatic gluing machine that can adjust the storage size of the support platform 42 through the first adjustment component 44 and the second adjustment component 44. While achieving automated operation, it can also adapt to different specifications and sizes of packaging materials, eliminating the need for manual adjustment and improving gluing efficiency.

[0081] The technical solutions of the embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0082] Please see Figures 1 to 2The present invention provides an automatic gluing machine, including a frame 1, having a first direction X, a second direction Y and a third direction Z that intersect each other in pairs;

[0083] The feeding mechanism 2 is mounted on the frame 1 and is used to transport the first workpiece 6 to the bonding station.

[0084] The glue application mechanism 3 is mounted on the frame 1. The glue application mechanism 3 is used to apply glue to the first workpiece 6 located in the feeding mechanism 2.

[0085] The feeding mechanism 4 is used to lift the second workpiece 7 located at the loading position to the receiving position. The feeding mechanism 4 includes a feeding bracket 41, a bearing platform 42, a first driving component 43, a first adjusting component 44, and a second adjusting component 44.

[0086] The feeding bracket 41 is slidably mounted on the frame 1 along the first direction X, and the bearing platform 42 is slidably mounted on the feeding bracket 41 along the third direction Z. The bearing platform 42 has a loading position for placing the second workpiece 7.

[0087] The first driving component 43, the first adjusting component 44 and the second adjusting component 44 are all mounted on the feeding bracket 41. The first driving component 43 is used to lift the carrying platform 42 to the receiving position. The first adjusting component 44 is used to adjust the storage length of the carrying platform 42 in the first direction X. The second adjusting component 44 is used to adjust the storage width of the carrying platform 42 in the second direction Y.

[0088] The transfer mechanism 5 is used to transport the second workpiece 7 located at the receiving position to the bonding position and bond the second workpiece 7 onto the first workpiece 6 after the adhesive has been applied.

[0089] It is understandable that both the first workpiece 6 and the second workpiece 7 are packaging pieces. For the sake of convenience in describing how the two packaging pieces are glued together, they are referred to as the first workpiece 6 and the second workpiece 7 respectively.

[0090] In this embodiment, the frame 1 is constructed from several welded square steel pipes. The feeding mechanism 2 is located inside the frame 1 along the first direction X. Its front end serves as the feeding end for the first workpiece 6, allowing for manual feeding or feeding via external equipment. The rear end serves as the bonding station. The feeding mechanism 2 transports the first workpiece 6 along the first direction X to the bonding station. The gluing mechanism 3 is positioned above the feeding mechanism 2 and is responsible for applying gluing to the upper surface of the first workpiece 6 during the conveying process. The feeding mechanism 4 is located on one side of the feeding mechanism 2. The horizontal height of its supporting platform 42 is lower than that of the feeding mechanism 2, facilitating the placement of multiple stacked second workpieces 7 on the supporting platform 42. Driven by the first driving component 43, the supporting platform 42 can move along the third direction Z, allowing the top layer of the second workpiece 7 within the supporting platform 42 to be lifted to the receiving position. The transfer mechanism 5 is located on one side of the loading mechanism 2 and the feeding mechanism 4. After the transfer mechanism 5 takes the second workpiece 7 from the receiving position, it moves the second workpiece 7 along the second direction Y, so that the second workpiece 7 is above the first workpiece 6 and fits against the upper surface of the first workpiece 6. When the dimensions of the first workpiece 6 and the second workpiece 7 change, the first adjustment component 44 and the second adjustment component 44 of the feeding mechanism 4 adjust the storage size of the bearing platform 42 to ensure the stability and reliability of the stacked second workpiece 7 during equipment operation, and to prevent the transfer mechanism 5 from failing to accurately align the upper surfaces of the second workpiece 7 and the first workpiece 6.

[0091] To improve the alignment between the first workpiece 6 and the second workpiece 7, the structure eliminates the need for a vision system to position the second workpiece 7. Based on the specific implementation described above, please refer to... Figures 3 to 6 The feeding mechanism 2 includes a feeding bracket 21, a belt conveyor 22, a first guide plate 23, a second guide plate 24, an adjusting component 25, and a limiting component 26;

[0092] The feeding bracket 21 is mounted on the frame 1, and the belt conveyor 22 is mounted on the feeding bracket 21 along the first direction X. The first guide plate 23 and the second guide plate 24 are both elongated structures. The first guide plate 23 is located on the first side of the belt conveyor 22, and the second guide plate 24 is located on the second side of the belt conveyor 22. The first side and the second side are the two sides of the first direction X. The first guide plate 23 and the second guide plate 24 are connected by an adjusting member 25. The adjusting member 25 is used to adjust the distance between the first guide plate 23 and the second guide plate 24.

[0093] The limiting component 26 is mounted on the frame 1 and located at the end edge of the fitting station. The limiting component 26 includes a limiting cylinder 260, a cylinder seat 261, a guide shaft 262, a baffle seat 263, and a baffle 264. The cylinder seat 261 is connected to the frame 1, and the limiting cylinder 260 is mounted on the cylinder seat 261. The output shaft of the limiting cylinder 260 is connected to the baffle seat 263. The baffle 264 is located on the side of the baffle seat 263 facing the feeding mechanism 2. Sliding holes are provided on the cylinder seat 261 and on both sides of the limiting cylinder 260. The guide shaft 262 passes through the sliding holes and connects to the baffle seat 263. The belt conveyor 22 is an existing technology and will not be described in detail here. The first guide plate 23 and the second guide plate 24 have the same structure and can both be made of metal or plastic. The first guide plate 23 is designed with an arc shape at the end furthest from the bonding station to reduce collision damage to the first workpiece 6. When the size of the first workpiece 6 changes, the distance between the first guide plate 23 and the second guide plate 24 can be adjusted by the adjusting member 25 to ensure that the first workpiece 6 is properly limited during transportation. When the first workpiece 6 reaches the bonding station, the limiting member 26 fixes it in place so that it can be bonded to the second workpiece 7. Specifically, the limiting cylinder 260 can extend and retract under the command of the control system. Before the first workpiece 6 and the second workpiece 7 are bonded, the limiting cylinder 260 remains extended so that the baffle 264 can contact the side of the first workpiece 6. Once the second workpiece 7 and the first workpiece 6 are bonded, the limiting cylinder 260 retracts, and the baffle 264 releases the first workpiece 6. Under the conveying action of the belt conveyor 22, the first workpiece 6 is discharged from the end of the feeding mechanism 2, and under the action of the limit cylinder 260, the baffle 264 moves up and down at the edge of the bonding station, which significantly improves the adaptability of the feeding mechanism 2 and ensures that the first workpiece 6 can be accurately positioned at the bonding station.

[0094] like Figure 6As shown, to improve the limiting stability of the first guide plate 23 and the second guide plate 24, in this embodiment, the number of adjusting members 25 is two. In some implementations, the adjusting member 25 includes a fixing plate 250, a first mounting plate 251, a second mounting plate 252, and a first adjusting screw 253.

Both the first mounting plate 251 and the second mounting plate 252 are provided with trapezoidal screw nuts. The two ends of the first adjusting screw 253 are rotatably connected to the bearings of the fixing plates 250 on both sides of the feeding bracket 21, and the first adjusting screw 253 is threadedly connected to the trapezoidal screw nuts of the first mounting plate 251 and the second mounting plate 252. The trapezoidal screw nuts of plate 251 and the second mounting plate 252 have opposite thread directions, so that the first guide plate 23 and the second guide plate 24 move closer to or further away from the central area of ​​the belt conveyor 22, allowing the first workpiece 6 to move along the sides of the first guide plate 23 and the second guide plate 24, thus achieving the limiting function of the first workpiece 6 of different specifications and sizes. The first adjusting screws 253 of the two adjusting components 25 are each equipped with a first sprocket 254. The two first sprockets 254 are connected by a chain belt, and one of the first adjusting screws 253 is also equipped with a rotating handwheel. By rotating the handwheel, the first adjusting screw 253 is rotated, and the other first adjusting screw 253 rotates synchronously under the drive of the first sprocket 254 and the chain belt. Under the action of the trapezoidal screw nuts, the first mounting plate 251 and the second mounting plate 252 move together toward the central area of ​​the belt conveyor.

[0095] In this embodiment, the adjusting component 25 drives the first guide plate 23 and the second guide plate 24 to be synchronously aligned via the first adjusting screw 253 with a reverse thread. The operator can adjust the limiting distance according to the width of the first workpiece 6 to prevent the conveyor from deviating. The support range covers workpieces with a width of 50-500mm. In addition, to improve the accuracy of synchronous alignment, the outer circumference of the first adjusting screw 253 is also engraved with graduations.

[0096] Furthermore, such as Figures 7 to 12 As shown, the glue application mechanism 3 includes a mounting frame 31, a glue application assembly 32, a height adjustment assembly 33, and a glue injection assembly 34;

[0097] The mounting frame 31 is mounted on the feeding mechanism 2, the glue application component 32 is slidably mounted on the mounting frame 31 along the third direction Z, and the height adjustment component 33 and the glue injection component 34 are both mounted on the mounting frame 31.

[0098] The glue application assembly 32 includes a main glue roller seat 320, a secondary glue roller seat 321, a main glue roller 322, a glue-passing roller 323, a glue-blocking seat 324, and a second drive assembly 325;

[0099] The main rubber roller seat 320 is slidably mounted on the mounting frame 31. The two ends of the glue-passing roller 323 are rotatably connected to the main rubber roller seat 320. The main rubber roller seat 320 has a cavity, and the slave rubber roller seat 321 is disposed within the cavity. The two ends of the main rubber roller 322 are rotatably connected to the slave rubber roller seat 321. The main rubber roller 322 and the glue-passing roller 323 are parallel, and there is a gap for glue flow between the main rubber roller 322 and the glue-passing roller 323. The glue-blocking seat 324 is connected to the main rubber roller seat 320. The glue-blocking seat 324 has a first recess 324a and a second recess 324b. The first recess 324a fits the outer periphery of the main glue roller 322, and the second recess 324b fits the outer periphery of the glue-passing roller 323. A glue-dropping area is formed between the main glue roller 322, the glue-passing roller 323, and the glue-blocking seat 324. The glue-dispensing assembly 34 communicates with the glue-dropping area. The glue-passing roller 323 makes rolling contact with the first workpiece 6 to transfer the glue layer on the surface of the glue-passing roller 323 to the upper surface of the first workpiece 6. The second drive assembly 325 is responsible for driving the main glue roller 322 to rotate, thereby driving the glue-passing roller 323 to rotate, to ensure that the glue layer on the surface of the glue-passing roller 323 maintains appropriate humidity, thereby avoiding a reduction in the viscosity of the glue layer due to excessive evaporation of moisture or solvent. The gap between the main glue roller 322 and the glue-passing roller 323 can be appropriately adjusted according to the viscosity characteristics of the glue, but this is not the only limitation.

[0100] Furthermore, the glue application assembly 32 also includes an adjusting plate 326 and an adjusting bolt 327. The adjusting plate 326 is located in the cavity. The first end of the adjusting bolt 327 is threadedly connected to the main glue roller seat 320 and then connected to the adjusting plate 326. The mounting bracket 31 is provided with an opening groove 31a to avoid the adjusting bolt 327. The second end of the adjusting bolt 327 is provided with a rotating handle. When it is necessary to adjust the gap between the main glue roller 322 and the glue-passing roller 323, the thread depth of the adjusting bolt 327 in the main glue roller seat 320 is adjusted by rotating the handle, thereby adjusting the position of the glue roller seat 321 in the cavity, and thus adjusting the gap between the main glue roller 322 and the glue-passing roller 323.

[0101] Furthermore, the height adjustment component 33 is used to adjust the horizontal height of the glue application component 32. The second drive component 325 includes a first motor 3251 and a first motor mounting plate 3252. The first motor 3251 is mounted on the first motor mounting plate 3252, which is fixed to the mounting bracket 31. A second sprocket 3253 is provided at the end of the main glue roller seat 320 and on the output shaft of the first motor 3251. The second sprocket 3253 of the main glue roller seat 320 and the second sprocket 3253 of the first motor 3251 are connected by a chain drive. Through the transmission between the second adjusting screw 331 and the trapezoidal screw nut of the main glue roller seat 320, combined with the vertical transmission design of the second bevel gear 335, millimeter-level fine-tuning of the height of the glue application component 32 is achieved, ensuring stable contact pressure between the glue roller 323 and the surface of the first workpiece 6, and avoiding defects such as excessive glue layer thickness or glue leakage.

[0102] Furthermore, the glue-blocking seat 324 includes a third mounting plate 3240, an adjusting block 3241, a spring 3242, an adjusting screw 3243, a fixing bolt 3244, and a glue-blocking block 3245. The third mounting plate 3240 is connected to the main glue roller seat 320. The third mounting plate 3240 is provided with an adjusting screw 3243 and a fixing bolt 3244. The fixing bolt 3244 passes through the adjusting block 3241 and is connected to the glue-blocking block 3245. One end of the adjusting screw 3243 abuts against the adjusting block 3241. The spring 3242 is sleeved on the fixing bolt 3244. Furthermore, the first end of the spring 3242 abuts against the adjusting block 3241, and the second end of the spring 3242 abuts against the glue-blocking block 3245. The spring 3242 cooperates with the adjusting screw 3243 to dynamically compensate for the gap changes between the glue-blocking block and the main glue roller 322 and the glue-passing roller 323, ensuring the sealing of the glue-dropping area. Combined with the temperature monitoring function of the glue injection groove 341 and the thermocouple, it ensures that the glue layer thickness is uniform and the viscosity is constant, which can reduce glue waste by 30%. With dynamic sealing, it prevents molten glue from overflowing from both ends of the roller body and contaminating the equipment, reducing the frequency of downtime maintenance by more than 50%. In addition, the detachable chamber design of the main glue roller 322 and the glue-passing roller 323 facilitates quick cleaning of residual glue, reducing the average daily maintenance time to within 10 minutes.

[0103] Furthermore, the third mounting plate 3240 is also connected to a thermocouple bracket 3246, which is equipped with thermocouples. The probe end of the thermocouple is located within the glue application area. The thermocouple is connected to an external temperature control device to monitor the glue temperature in the application area and ensure that the glue temperature in this area is maintained within a suitable range. This arrangement aims to prevent the glue viscosity from decreasing due to excessively low temperature, thus avoiding poor leveling of the glue on the glue roller 323 and preventing the formation of an uneven glue layer on the first workpiece 6. In addition, the heating elements on the glue roller 323 and the main glue roller 322 can reduce the frequency of manual wiping of the glue roller 323 and the main glue roller 322, further improving the bonding efficiency.

[0104] Furthermore, the height adjustment assembly 33 includes a fourth mounting plate 330, a second adjusting screw 331, a transmission rod 332, and a third drive assembly 333. The fourth mounting plate 330 is mounted on the mounting brackets 31 located on both sides of the feeding mechanism 2. The two ends of the transmission rod 332 are rotatably connected to the two fourth mounting plates 330 respectively, and the two ends of the transmission rod 332 are provided with first bevel gears 334.

[0105] Furthermore, the third drive assembly 333 includes a second motor 3331 and a second motor mounting plate 3332. The second motor mounting plate 3332 is connected to the mounting bracket 31. The second motor 3331 is mounted on the second motor mounting plate 3332. The output shaft of the second motor 3331 and the transmission rod 332 are both provided with a third sprocket 3333. The third sprocket 3333 of the second motor 3331 and the third sprocket 3333 of the transmission rod 332 are connected by a chain drive.

[0106] The mounting bracket 31 is provided with a vertical bearing, the second adjusting screw 331 is housed in the vertical bearing, the main rubber roller seat 320 is provided with a trapezoidal screw nut, the second adjusting screw 331 is threadedly engaged with the trapezoidal screw nut of the main rubber roller seat 320, one end of the second adjusting screw 331 is provided with a second bevel gear 335, and the first bevel gear 334 is meshed with the second bevel gear 335.

[0107] Furthermore, the glue injection assembly 34 includes a glue injection groove 341 and a fixing frame 342. The fixing frame 342 is connected to the mounting frame 31. The glue injection groove 341 is disposed on the fixing frame 342. The glue injection groove 341 is provided with a liquid injection hole, which corresponds to the glue drop area.

[0108] Furthermore, the gluing roller 323 consists of a roller body 323a made of metal and a heating element 323b. The roller body 323a has a groove extending through both axial ends, and the heating element 323b is housed within this groove. The heating element 323b is connected to an external power source, and heat is transferred to the roller body 323a through the heating element 323b to maintain a constant glue temperature within the glue application area. This configuration not only improves the adhesive properties of the glue but also ensures that the glue flows at an appropriate viscosity on the outer peripheral surfaces of the gluing roller 323 and the main glue roller 322, forming a uniformly thick glue layer. In a preferred embodiment, to ensure that the solvent in the glue layer of the main glue roller 322 does not evaporate, the gluing roller 323 and the main glue roller 322 have the same structure.
