Description

Technical Field

[0001] This invention belongs to the field of packaging equipment technology, and in particular relates to a high-speed hot melt adhesive sealing machine and sealing method. Background Technology

[0002] With the development of the internet age, the number of online shoppers has gradually increased, driving the rapid development of the logistics industry and increasing our demand for logistics services. Therefore, the requirements for the production efficiency and quality of boxes are becoming higher, leading to a significant increase in the demand for box sealing machines during box forming.

[0003] Traditional hot melt adhesive sealing of finished boxes mainly relies on a center-side drive method. Workers spray adhesive onto the box using a glue gun and then press the lid shut. This sealing method is cumbersome and has low accuracy. Manual sealing also results in low efficiency. To address these issues, we provide a high-speed hot melt adhesive sealing machine and sealing method. Summary of the Invention

[0004] The purpose of this invention is to provide a high-speed hot melt adhesive carton sealing machine and method. The machine utilizes a power drive assembly to transport a pre-formed carton to the edge of the sealing plate. An automatic glue sprayer dispenses hot melt adhesive into the gaps on both sides of the carton. A lifting and pressing assembly then gently presses the carton. Once the carton is bonded, the lifting and pressing assembly moves upwards, and the carton enters a collection hole. The lifting and pressing assembly is then lowered again, causing the carton to fall onto the first support base. Finally, workers collect the sealed cartons. This invention solves the problems of cumbersome sealing processes, low accuracy, and low efficiency associated with manual sealing.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0008] The present invention is further configured such that a high-speed hot melt adhesive carton sealing machine also includes a support component, the support component including a first support base, the peripheral side of the first support base being fixedly connected to the conveying inclined plate, the first support base being fixedly disposed below the sealing plate, a first drive motor being installed at the bottom of the first support base, a second support base being fixedly disposed below the first support base, the top of the second support base being fixedly connected to the bottom of the conveying inclined plate, the top of the second support base being rotatably connected coaxially to the bottom of the first bevel gear, a second drive motor being installed at the bottom of the second support base, and the output shaft of the second drive motor being fixedly coaxially connected to the first bevel gear.

[0009] The present invention is further configured such that the lifting and pressing assembly includes a plurality of first pressing rods and a plurality of second pressing rods, the tops of the first pressing rods and the second pressing rods being fixedly connected to the pressing plate, the first pressing rods corresponding to the collecting holes and located above the corresponding collecting holes, and the second pressing rods corresponding to the conveying inclined plate and located above the conveying inclined plate.

[0010] The present invention is further configured such that an internally threaded sleeve is fixedly provided at the bottom of the extrusion plate, the internally threaded sleeve is slidably engaged with the sliding hole, a threaded rod is rotatably provided at the top of the first bearing base, the bottom of the threaded rod is fixedly connected coaxially with the output shaft of the first drive motor, and the threaded rod and the internally threaded sleeve are threadedly engaged.

[0011] The present invention is further configured such that the conveying assembly includes a conveying plate, the conveying plate is slidably disposed on the surface of the conveying inclined plate, a connector is fixedly disposed on one side of the conveying inclined plate, a first pulley and a second pulley are rotatably disposed on the side of the conveying inclined plate near the connector, a drive gear ring is fixedly disposed on the circumferential side of the first pulley, the first pulley and the second pulley are connected by a first transmission belt, and the first transmission belt is fixedly connected to the conveying plate by the connector.

[0012] The present invention is further configured such that the power drive assembly further includes a second bevel gear, the second bevel gear corresponds one-to-one with the conveying inclined plate, the second bevel gear meshes with the first bevel gear, a first connecting rod is fixedly provided on one side of the second bevel gear, a third pulley is fixedly provided on the end of the first connecting rod away from the second bevel gear, and a second connecting rod is fixedly provided on the side of the third pulley away from the first connecting rod.

[0013] The present invention is further configured such that a transmission groove is provided on the side of the conveying sloping plate near the second bevel gear, a limiting plate corresponding to the conveying sloping plate is fixedly provided on the top of the second bearing base, and a driving rack is slidably provided on the side of the limiting plate near the first pulley, and one side of the driving rack meshes with the driving gear ring.

[0014] The present invention is further configured such that a drive gear is rotatably disposed on the side of the limiting plate near the drive rack, the drive gear meshes with the drive rack, a third connecting rod is fixedly disposed on the side of the drive gear away from the limiting plate, a fourth pulley is fixedly disposed on one end of the third connecting rod, the fourth pulley is connected to the third pulley by a second transmission belt, and the second transmission belt is disposed inside the transmission groove.

[0015] The present invention has the following beneficial effects:

[0016] 1. This invention uses a power drive component to drive a conveying component to transport the formed box. The formed box is delivered to the edge of the sealing plate. Activating the spray button activates the automatic glue sprayer, which sprays hot melt adhesive into the gaps on both sides of the box. Then, the lifting and pressing component moves down, using the second pressing rod to gently press the box, making the hot melt adhesive adhere more firmly. Once the box is bonded, the lifting and pressing component moves up. When the second pressing rod disengages from the box, the conveying component continues to transport the box. When the box enters the collection hole, the lifting and pressing component is lowered again. The box, under its own weight and the pressing force of the first pressing rod, falls from the collection hole onto the first carrier base. Workers can then collect the sealed box, making the operation simpler and more convenient, and eliminating the need for manual glue application and sealing.

[0017] 2. The present invention drives the first pulley to rotate through the power drive component, causing the first transmission belt to move upward, which in turn causes the conveyor plate to move upward. At this time, the box moves upward synchronously with the conveyor plate. When the second drive motor reverses, the first pulley rotates in the opposite direction, causing the first transmission belt to move downward and drive the conveyor plate downward until the conveyor plate returns to its initial position. During this process, the box is automatically conveyed, which greatly saves time and costs.

[0018] 3. This invention starts the second drive motor, causing the first bevel gear to rotate and simultaneously driving multiple second bevel gears to rotate. This causes the third pulley to rotate synchronously and drive the fourth pulley to rotate. At this time, the drive gear rotates with the fourth pulley, and at the same time, the drive rack moves down and drives the first pulley to rotate. The conveyor plate then carries the box upward. During this process, multiple conveying components simultaneously convey the box, and one machine can seal multiple boxes at the same time, greatly improving the sealing efficiency.

[0019] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] For a specific implementation example, please refer to Implementation Example 1. Figure 1-9This invention relates to a high-speed hot melt adhesive carton sealing machine, comprising a sealing assembly 1, a lifting and extrusion assembly 2, a conveying assembly 3, and a power drive assembly 4. The sealing assembly 1 includes a sealing plate 101, with a plurality of collection holes 102 on the top of the sealing plate 101. The sealed boxes are collected through the collection holes 102. An arc-shaped plate 103 corresponding to each collection hole 102 is fixedly installed on the top of the sealing plate 101. The arc-shaped plate 103 is used to install an automatic glue sprayer (the automatic glue sprayer consists of a glue spraying box, a controller, a robotic arm, and a glue spraying nozzle. When the controller is activated, the robotic arm moves to drive the glue spraying nozzle to the corresponding position on the box, thereby spraying glue onto the gaps of the box to achieve the purpose of sealing the box).

[0034] The lifting and pressing assembly 2 is installed inside the sealing plate 101. The lifting and pressing assembly 2 includes a pressing plate 201, which is located above the sealing plate 101. The pressing plate 201 is used to press the sprayed box to make the sealed box more secure. The pressed box falls through the collection hole 102 and can be collected.

[0035] The conveying assembly 3 is installed on the periphery of the sealing plate 101. The conveying assembly 3 includes a plurality of conveying inclined plates 301. The conveying inclined plates 301 are fixedly arranged on the periphery of the sealing plate 101, and the conveying inclined plates 301 correspond one-to-one with the collection holes 102.

[0036] The power drive assembly 4 is installed below the conveying inclined plate 301. The power drive assembly 4 includes a first bevel gear 401, which simultaneously drives several conveying assemblies 3 to convey and encapsulate the box.

[0037] Specifically, a sliding hole 105 is provided on the top of the sealing plate 101 (the sliding hole 105 is located in the middle of the sealing plate 101). The sliding hole 105 is slidably engaged with the lifting and pressing assembly 2. Several baffles are fixedly provided on the top of the sealing plate 101. The baffles are fixedly connected to the arc plate 103. The baffles are evenly distributed on the top of the sealing plate 101. A conveying inclined plate 301 is installed between two adjacent baffles. The collection hole 102 is located between two adjacent baffles.

[0038] A high-speed hot melt adhesive carton sealing machine also includes a support component 5, which includes a first support base 501. The periphery of the first support base 501 is fixedly connected to the conveying inclined plate 301. The first support base 501 is fixedly disposed below the sealing plate 101. A first drive motor is installed at the bottom of the first support base 501. A second support base 502 is fixedly disposed below the first support base 501. A support rod is provided at the bottom of the second support base 502. The top of the second support base 502 is fixedly connected to the bottom of the conveying inclined plate 301. The top of the second support base 502 is rotatably connected to the bottom of the first bevel gear 401 on the same axis. A second drive motor is installed at the bottom of the second support base 502. The output shaft of the second drive motor is fixedly connected to the first bevel gear 401 on the same axis.

[0039] Furthermore, the lifting and pressing assembly 2 also includes a plurality of first pressing rods 202 and a plurality of second pressing rods 203. The tops of the first pressing rods 202 and the second pressing rods 203 are fixedly connected to the pressing plate 201. The first pressing rods 202 correspond to the collection holes 102 and are located above the corresponding collection holes 102. The second pressing rods 203 correspond to the conveying inclined plate 301 and are located above the conveying inclined plate 301.

[0040] The operation process of this embodiment is as follows: In the initial state, the automatic glue sprayer is in the off state, the lifting and extrusion assembly 2 is at its highest position, and the box body that has been stretched and formed is at its lowest position. The second drive motor is started, and the power drive assembly 4 drives the conveyor assembly 3 to move upward. The box body moves upward synchronously with the conveyor assembly 3. When the box body reaches the edge of the sealing plate 101, the second drive motor is turned off, and at the same time, the controller in the automatic glue sprayer is turned on, so that the robotic arm sprays glue on the gaps of the box body that need to be sealed. After the hot melt glue enters the gaps of the box body, the automatic glue sprayer is turned off. At this time, the first drive motor is started, and the second extrusion rod 203 in the lifting and extrusion assembly 2 moves downward. When the second extrusion rod 203 reaches the top of the box body, the first drive motor is turned off. At this time, the second drive motor is started. The two extrusion rods 203 apply slight pressure to the box body to make the hot melt adhesive more secure. After the box body is glued, the first drive motor is reversed, so that the lifting extrusion assembly 2 returns to its initial position. Then, the second drive motor is started to continue to control the conveying assembly 3 to convey the box body. When the box body enters the collection hole 102, the second drive motor is turned off and the first drive motor is started, so that the lifting extrusion assembly 2 moves down again, driving the first extrusion rod 202 to move down and extrude the box body again. The box body in the collection hole 102 falls to the top of the first support base 501 under its own weight and the action of the first extrusion rod 202, and the staff can then collect the box body. At this time, the first drive motor and the second drive motor are reversed, so that the lifting extrusion assembly 2 and the conveying assembly 3 return to their initial positions.

[0041] In a second specific embodiment, based on the first specific embodiment, an internally threaded sleeve 204 is fixedly provided at the bottom of the extrusion plate 201, and the internally threaded sleeve 204 is slidably engaged with the sliding hole 105.

[0042] Specifically, a threaded sleeve 205 is rotatably provided on the top of the first bearing base 501. The bottom of the threaded sleeve 205 is fixedly connected to the output shaft of the first drive motor on the same axis. The threaded sleeve 205 and the internal threaded sleeve 204 are threadedly engaged.

[0043] Furthermore, the conveying assembly 3 also includes a conveying plate 302, which is slidably disposed on the surface of the conveying inclined plate 301. A connector is fixedly disposed on one side of the conveying inclined plate 301. A first pulley 303 and a second pulley 304 are rotatably disposed on the side of the conveying inclined plate 301 near the connector. A drive gear ring 305 is fixedly disposed on the circumferential side of the first pulley 303. The first pulley 303 and the second pulley 304 are connected by a first transmission belt 306. The first transmission belt 306 and the conveying plate 302 are fixedly connected by the connector. The connector connects the first transmission belt 306 and the conveying plate 302. Initially, the connector is located at the lowest position. When the first transmission belt 306 rotates to the highest position, the connector reaches the highest position. Subsequently, the first transmission belt 306 moves down, and the connector returns to the initial position. The connector causes the conveying plate 302 to move up and down under the drive of the first transmission belt 306.

[0044] The operation process of this embodiment is as follows: In the initial state, the conveyor plate 302 is at the lowest position. The second drive motor is started. At this time, the power drive component 4 drives the first pulley 303 to rotate, causing the first transmission belt 306 to rotate. At the same time, the conveyor plate 302 moves upward. At this time, the box moves upward synchronously with the conveyor plate 302. When the second drive motor reverses, the first pulley 303 rotates in the opposite direction, causing the first transmission belt 306 to move downward, driving the conveyor plate 302 downward until the conveyor plate 302 returns to the initial position.

[0045] In a specific embodiment three, based on specific embodiments one and two, the power drive assembly 4 further includes a second bevel gear 402, which corresponds one-to-one with the conveying inclined plate 301, and the second bevel gear 402 meshes with the first bevel gear 401.

[0046] A first connecting rod 403 is fixedly installed on one side of the second bevel gear 402. A third pulley 404 is fixedly installed on the end of the first connecting rod 403 away from the second bevel gear 402. A second connecting rod is fixedly installed on the side of the third pulley 404 away from the first connecting rod 403.

[0047] Specifically, a transmission groove 405 is provided on the side of the conveying inclined plate 301 near the second bevel gear 402. The transmission groove 405 is located at the lower end of the conveying inclined plate 301 and inside the conveying inclined plate 301. See the attached document for details. Figure 6 As shown, the transmission groove 405 extends horizontally from the middle of its lower end (see attached diagram for details). Figure 7 As shown, the second carrier base 502 is fixedly provided with a limiting plate 406 corresponding to the conveying inclined plate 301. A driving rack 407 is slidably provided on the side of the limiting plate 406 near the first pulley 303 (the driving rack 407 is provided with a toothed structure on the side near the first pulley 303 and the side away from the conveying inclined plate 301). One side of the driving rack 407 meshes with the driving gear ring 305.

[0048] Furthermore, a drive gear 408 is rotatably mounted on the side of the limiting plate 406 near the drive rack 407, and the drive gear 408 meshes with the drive rack 407. A third connecting plate 409 is fixedly mounted on the side of the drive gear 408 away from the limiting plate 406. A fourth pulley is fixedly mounted on one end of the third connecting rod 409. The fourth pulley and the third pulley 404 are connected by a second transmission belt, which is located inside the transmission groove 405.

[0049] The operation process of this embodiment is as follows: In the initial state, the drive rack 407 is in the highest position (see attached diagram for details). Figure 7 As shown, when the conveyor plate 302 is at its lowest position, it drives the second drive motor. The first bevel gear 401 rotates, causing the second bevel gear 402 to rotate, which in turn causes the third pulley 404 to rotate synchronously, driving the fourth pulley to rotate. At this time, the drive gear 408 rotates along with the fourth pulley. Simultaneously, the drive rack 407 moves downward, causing the first pulley 303 to rotate. The conveyor plate 302 then carries the box upward. When the box is finished being conveyed, the second drive motor reverses, causing the first bevel gear 401 to rotate in the opposite direction, which in turn causes the second bevel gear 402 to rotate in the opposite direction. This causes the third pulley 404 to rotate in the opposite direction, driving the fourth pulley to rotate in the opposite direction. At this time, the drive gear 408 rotates in the opposite direction along with the fourth pulley. Simultaneously, the drive rack 407 moves upward, causing the first pulley 303 to rotate in the opposite direction. The conveyor plate 302 then returns to its initial position.

[0050] In a specific embodiment four, the present invention also includes a sealing method for a high-speed hot melt adhesive sealing machine, comprising the following steps:

[0051] S01: In the initial state, the second drive motor is off, the drive rack 407 is at its highest position, the formed box is placed on the conveyor plate 302, the second drive motor is started, the first bevel gear 401 rotates and drives the second bevel gear 402 to rotate, so that the third pulley 404 rotates synchronously and drives the fourth pulley to rotate. At this time, the drive gear 408 rotates with the fourth pulley, and at the same time, the drive rack 407 moves down and drives the first pulley 303 to rotate.

[0052] S02: In the initial state, the conveyor plate 302 is at the lowest position. When the first pulley 303 rotates under the drive of the drive rack 407, it drives the first transmission belt 306 to rotate, thereby driving the first transmission belt 306 to rotate. At this time, the conveyor plate 302 will move the box upward.

[0053] S03: In the initial state, the glue outlet tube 104 is closed. When the box reaches the edge of the sealing plate 101, the second drive motor is turned off and the automatic glue sprayer is turned on. At this time, the automatic glue sprayer is used to spray the gaps on both sides of the box. After the hot melt glue enters the gaps in the box, the automatic glue sprayer is turned off.

[0054] S04: In the initial state, the first drive motor is off. When the hot melt adhesive is sprayed, the first drive motor is started and the second extrusion rod 203 moves downward. When the second extrusion rod 203 reaches the top of the conveying inclined plate 301, the first drive motor is turned off. At this time, the second extrusion rod 203 is used to slightly press the top of the box to make the hot melt adhesive more firm. After the box is glued, the first drive motor is reversed so that the second extrusion rod 203 returns to the initial position.

[0055] S05: Then start the second drive motor to continue controlling the conveyor plate 302 to transport the box. When the box enters the collection hole 102, turn off the second drive motor and start the first drive motor to make the lifting and pressing component 2 move down again, driving the first pressing rod 202 to move down and press the box again. The box in the collection hole 102 will fall back to the top of the first bearing base 501 under its own weight and the action of the first pressing rod 202. The staff can then collect the box. At this time, reverse the first drive motor and the second drive motor to make the lifting and pressing component 2 and the conveyor plate 302 return to the initial position. Repeat the above steps to continuously seal the box.

A fourth pulley is fixedly provided at one end of the third connecting rod (409). The fourth pulley and the third pulley (404) are connected by a second transmission belt, which is located inside the transmission groove (405).

5. The method of claim 4, wherein the method further comprises: Includes the following steps: S01: In the initial state, the second drive motor is in the off state, the drive rack (407) is in the highest position, the formed box is placed on the conveyor plate (302), the second drive motor is started, the first bevel gear (401) rotates and drives the second bevel gear (402) to rotate, so that the third pulley (404) rotates synchronously and drives the fourth pulley to rotate. At this time, the drive gear (408) rotates with the fourth pulley, and at the same time, the drive rack (407) moves down and drives the first pulley (303) to rotate. S02: In the initial state, the conveyor plate (302) is at the lowest position. When the first pulley (303) rotates under the drive of the drive rack (407), it drives the first pulley (303) to rotate, thereby driving the first transmission belt (306) to rotate. At this time, the conveyor plate (302) will move the box upward. S03: In the initial state, the automatic glue sprayer is in the closed state. When the box reaches the edge of the sealing plate (101), the second drive motor is turned off and the automatic glue sprayer is turned on at the same time. At this time, the automatic glue sprayer is used to spray the gaps on both sides of the box. After the hot melt glue enters the gaps in the box, the automatic glue sprayer is turned off. S04: In the initial state, the first drive motor is in the off state. When the hot melt adhesive is sprayed, the first drive motor is started and the second extrusion rod (203) moves downward. When the second extrusion rod (203) reaches the top of the conveying ramp (301), the first drive motor is turned off. At this time, the second extrusion rod (203) is used to slightly extrude the top of the box to make the hot melt adhesive more firm. After the box is glued, the first drive motor is reversed so that the second extrusion rod (203) returns to the initial position. S05: Then start the second drive motor to continue controlling the conveyor plate (302) to transport the box. When the box enters the collection hole (102), turn off the second drive motor and start the first drive motor so that the lifting and pressing assembly (2) moves down again, driving the first pressing rod (202) to move down and press the box again. The box in the collection hole (102) falls to the top of the first carrier base (501) under its own weight and the action of the first pressing rod (202). The staff can then collect the box. At this time, reverse the first drive motor and the second drive motor so that the lifting and pressing assembly (2) and the conveyor plate (302) return to the initial position. Repeat the above steps to continuously seal the box.
