Description

Technical Field

[0001] The present invention relates to the technical field of dispensing, and particularly relates to a dispensing device for gift box production. Background Art

[0002] As a gift packaging, the outer side of the gift box body is usually covered with a beautiful decorative sticker. During the production of the gift box, a dispensing machine is usually used to dispense glue on the original box body board, and then the decorative sticker is pasted on the surface of the board to achieve the effect of beautification and decoration.

[0003] Chinese Patent with the publication number CN112810178B discloses an automatic dispensing machine, which can simultaneously perform dispensing on plastic shell products and bend insulating sheets, and assemble the bent insulating sheets on the plastic shell products for riveting.

[0004] However, when dispensing glue on the product surface by the above device and most dispensing machines on the market, the glue liquid extruded from the dispensing head moves with the dispensing head and forms a narrow linear shape, and the thickness of the glue liquid after extrusion is also high due to the pressure of the glue liquid extruded from the dispensing head. The decorative sticker needs to be attached to the box body board in a large area, and the thin and thick glue liquid will cause some areas between the decorative sticker and the box body board to lack glue and bulge, and some areas will have too thick glue liquid, resulting in the decorative sticker and the box body board not being able to be laid flat, with unevenness and even glue overflow at the edge, which not only causes waste of glue liquid, but also affects the beauty of the product. Summary of the Invention

[0005] Aiming at the deficiencies of the existing technology, the present invention proposes a dispensing device for gift box production to solve the above problems.

[0006] The purpose of the present invention is achieved through the following technical solutions: A dispensing device for gift box production provided by the present invention includes a machine table, on which a frame is installed. A movable seat that can move horizontally and vertically is installed on the frame. A glue extrusion cylinder is installed on the movable seat, and a dispensing head is installed at the bottom end of the glue extrusion cylinder. The device further includes: A mounting plate, which is installed on one side of the dispensing head through an adjustment mechanism. The adjustment mechanism can move the mounting plate to the rear side of the path where the dispensing head passes. A lower pressing plate is connected to the lower part of the mounting plate through a first spring. A sliding column that longitudinally penetrates through the mounting plate is arranged on the top of the lower pressing plate; A bottom block, which is installed at the bottom of the lower pressing plate and has a recovery cavity inside. A flat laying groove is opened at the bottom of the bottom block. Both sides of the flat laying groove close to and away from the dispensing head are open. A recovery groove is opened on one side of the bottom block close to the dispensing head. The bottom of the recovery groove communicates with the flat laying groove and a recovery port communicating with the recovery cavity is opened on the side away from the dispensing head. A rotating cylinder is rotatably installed in the recovery groove, and the outer wall of the rotating cylinder abuts against the bottom side of the recovery port; A driving mechanism capable of driving the rotating cylinder to rotate.

[0007] Furthermore, the adjusting mechanism includes a substrate and a U-shaped buckle. The substrate is mounted on the movable seat and penetrated by the dispensing head. An arc-shaped chute is provided on the substrate with the dispensing head as the center of the circle. An adjusting block is slidably mounted in the arc-shaped chute. The U-shaped buckle is disposed on the mounting plate and its end is fixedly connected to the adjusting block.

[0008] Furthermore, an external gear ring is provided on the edge of the substrate with the dispensing head as the center of the circle. A motor is fixedly mounted on the U-shaped buckle, and a first gear meshing with the external gear ring is mounted at the output shaft end of the motor.

[0009] Furthermore, a camshaft is provided on one side of the recovery groove. A convex portion is provided on the side of the camshaft facing the recovery port. A rotating hole is opened on the other side of the recovery groove. One end of the rotating cylinder is provided with a rotating shaft and the other end is provided with a through hole for the camshaft to penetrate. The rotating shaft is rotatably mounted in the rotating hole. A plurality of glue storage grooves are circumferentially and evenly distributed on the rotating cylinder. A push block is slidably mounted in each glue storage groove. A second spring is connected between the inner end of the push block and the inner wall of the rotating cylinder to provide an elastic force to make the inner end of the push block abut against the surface of the camshaft and make the push block retract into the glue storage groove. The convex portion can push the outer end of the push block to the edge of the notch of the glue storage groove.

[0010] Furthermore, the driving mechanism includes a second gear, a third gear and two roller groups. Each roller group includes three rollers. The two roller groups are symmetrically mounted on both sides of the bottom block. Two of the rollers in each roller group have the same height and the other roller is at the highest position. A belt is provided around the outside of each roller group. The second gear is mounted on the roller at the highest position in one of the roller groups. The third gear meshing with the second gear is mounted on the rotating shaft.

[0011] Furthermore, the end of the rotating shaft away from the rotating cylinder is located outside the bottom block and is provided with a driving disk. A wave track is provided around the rotating shaft on the side of the driving disk facing the bottom block. An insertion groove is opened on the inner wall of the recovery groove away from the rotating shaft and a through groove is opened on the other inner wall. The insertion groove and the through groove are coaxially arranged and are located on the side of the recovery groove close to the dispensing head. A leveling rod is slidably penetrated in the through groove. One end of the leveling rod penetrates into the insertion groove and a third spring is connected between the leveling rod and the insertion groove. The third spring can provide an elastic force to make the other end of the leveling rod abut against the wave track.

[0012] Further, it further includes a glue storage mechanism, which includes a glue storage bin, a piston rod and a connecting pipe. The glue storage bin is arranged on the mounting plate. The piston rod penetrates through the bottom of the glue storage bin and its bottom end is connected to the lower pressing plate. Two one-way valves leading in opposite directions are respectively arranged at the top of the glue storage bin. One end of the connecting pipe is connected to the one-way valve that only allows substances to enter the glue storage bin, and the other end is communicated with the recovery cavity.

[0013] Further, a threaded port communicated with the recovery cavity is arranged on the outer side of the bottom block, and the end of the connecting pipe is threadedly connected to the threaded port.

[0014] As can be seen from the above technical solutions, a glue dispensing device for gift box production provided by the present invention: 1. By adjusting the position of the mounting plate through the adjusting mechanism to adjust the position of the bottom block, so that no matter where the glue dispensing head moves, the flattening groove can pass through the coating path of the glue, and the flattening groove can widen and thin the narrow and thick glue, increasing the contact surface between the glue and the decorative sticker, improving the adhesion between the decorative sticker and the box body board, and at the same time enabling the decorative sticker to be flatly laid on the box body board, improving the surface flatness, greatly reducing the occurrence of edge glue overflow, and through the rotating cylinder, using the viscosity of the glue, the excess glue waste can also be recycled into the recovery cavity, realizing the full utilization of the glue and being beneficial to reducing the waste of the glue; 2. The glue storage tank can store a certain amount of glue additionally, improving the transfer amount of the glue waste by the rotating cylinder. When the pushing block reaches the recovery port as the rotating cylinder rotates, the convex portion can push the outer end of the pushing block to the edge of the slot opening of the glue storage tank, and then push the glue in the glue storage tank into the recovery cavity through the recovery port, and the continuous rotation of the rotating cylinder will scrape off the glue on the surface of the rotating cylinder and the outer end of the pushing block at the recovery port, so that the rotating cylinder can recycle and transfer the glue waste in subsequent cycles; 3. As the glue dispensing head moves, the belt will also roll on the surface of the board and drive each roller to rotate, and then drive the rotating cylinder to rotate through the meshing of the second gear and the third gear, realizing the simultaneous transfer and recovery of the glue waste while performing the glue dispensing operation, making the glue dispensing and glue flattening cooperate with each other, improving the glue dispensing efficiency, and moreover, the belt rolling on the surface of the board is also beneficial to reducing the frictional resistance between the bottom block and the board; 4. During the glue dispensing operation, the rotating cylinder rotates under the drive of the drive mechanism to recover the glue waste, the drive disk rotates as the rotating cylinder rotates, and the uneven surface of the wave track will continuously pass by the end of the leveling rod. With the elastic force of the third spring, the leveling rod can be continuously pushed back and forth. When the leveling rod passes through the narrow and thick glue, it can spread the glue to both sides, enabling the glue to be widened and thinned more quickly by the flattening groove subsequently; 5. By using the up-and-down movement of the movable seat during each dispensing operation and cooperating with the first spring, the lower pressing plate can periodically approach and move away from the mounting plate, thereby driving the piston rod to move with the start and end of dispensing. Gas in the glue storage chamber is discharged in advance at the start of each dispensing operation for preparation, and the glue waste in the recovery chamber is absorbed after the end of each dispensing operation, so that there is enough recovery space in the recovery chamber at the start of each dispensing operation, and finally the glue waste is centrally collected into the glue storage chamber.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] To further elaborate on the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following will, in conjunction with the accompanying drawings and preferred embodiments, elaborate in detail on the specific implementation manners, structures, features and their effects according to the present invention as follows.

[0018] As Figures 1-6 shown, a dispensing device for gift box production provided in this embodiment includes a machine table 1, on which a frame 11 is installed. A movable seat 12 that can move horizontally and vertically is installed on the frame 11. A glue extrusion cylinder 13 is installed on the movable seat 12, and a dispensing head 14 is installed at the bottom end of the glue extrusion cylinder 13. The machine table 1 can be a conventional dispensing machine table sold on the market. The movable seat 12 and the frame 11 can achieve the moving function through the connection mode of an electric slide rail. The glue extrusion cylinder 13 can extrude the internal glue liquid from the bottom end of the dispensing head 14. The above are all prior arts, so no more details will be described here. The present invention further includes a mounting plate 2, an adjusting mechanism 3, a bottom block 4 and a driving mechanism 5.

[0019] The mounting plate 2 is installed on one side of the dispensing head 14 through the adjusting mechanism 3, and the adjusting mechanism 3 can move the mounting plate 2 to the rear side of the path where the dispensing head 14 travels.

[0020] Specifically, the adjusting mechanism 3 includes a base plate 31 and a U-shaped buckle 32. The base plate 31 is installed on the movable seat 12 and penetrated by the dispensing head 14. An arc-shaped sliding groove 311 is arranged on the base plate 31 with the dispensing head 14 as the center of the circle. An adjusting block 312 is slidably installed in the arc-shaped sliding groove 311. The U-shaped buckle 32 is arranged on the mounting plate 2 and its end is fixedly connected to the adjusting block 312.

[0021] Furthermore, an external gear ring 313 is arranged on the edge of the base plate 31 with the dispensing head 14 as the center of the circle. A motor 321 is fixedly installed on the U-shaped buckle 32, and a first gear 322 meshing with the external gear ring 313 is installed at the output shaft end of the motor 321. Starting the motor 321 can make the first gear 322 rotate, drive the first gear 322 to roll through meshing with the external gear ring 313, and then drive the U-shaped buckle 32 to rotate around the dispensing head 14. No matter in which direction the dispensing head 14 moves, the adjusting mechanism 3 can drive the mounting plate 2 to move to the rear side of the moving path of the dispensing head 14, so as to level and thin the glue liquid extruded by the dispensing head 14.

[0022] Preferably, the adjusting block 312 is installed between the two ends of the U-shaped buckle 32, so that the external gear ring 313 can be clamped between the two ends of the U-shaped buckle 32, improving the stability of the U-shaped buckle 32 when moving.

[0023] Below the mounting plate 2, a lower pressing plate 22 is connected by a first spring 21. The first spring 21 can provide an elastic force to push the lower pressing plate 22 downward. A sliding column 23 longitudinally penetrating the mounting plate 2 is provided at the top of the lower pressing plate 22, so that the lower pressing plate 22 can slide longitudinally based on the mounting plate 2.

[0024] The bottom block 4 is installed at the bottom of the lower pressing plate 22 and has a recovery cavity 41 inside. A flat laying groove 42 is opened at the bottom of the bottom block 4. The flat laying groove 42 is flat. Both sides of the flat laying groove 42 close to and away from the dispensing head 14 are open to bring in and take out the glue. It should be noted that the bottom height of the bottom block 4 should be lower than the bottom height of the dispensing head 14. A recovery groove 43 is opened on one side of the bottom block 4 close to the dispensing head 14. The bottom of the recovery groove 43 communicates with the flat laying groove 42, and a recovery port 431 communicating with the recovery cavity 41 is opened on the side away from the dispensing head 14. A rotating cylinder 44 is rotatably installed in the recovery groove 43, and the outer wall of the rotating cylinder 44 abuts against the bottom side of the recovery port 431.

[0025] The driving mechanism 5 can drive the rotating cylinder 44 to rotate.

[0026] Each time dispensing operation is performed, the movable seat 12 will move downward to make the dispensing head 14 close to the surface of the box board. During the process of the dispensing head 14 approaching the board, the bottom of the bottom block 4 will first contact the board and compress the first spring 21 to make the lower pressing plate 22 close to the mounting plate 2, so that the bottom block 4 can receive a downward reaction force and abut against the surface of the board. During the process of the dispensing head 14 moving with the movable seat 12 and extruding the glue to coat the surface of the board, the bottom block 4 will continuously pass through the coating path of the glue, and the narrow and thick glue will be widened and thinned through the flat laying groove 42. The driving mechanism 5 drives the rotating cylinder 44 to rotate, and can utilize the viscosity of the glue to attach the excess glue to its surface and roll it for transportation. Since the outer wall of the rotating cylinder 44 abuts against the bottom side of the recovery port 431, when the glue on the rotating cylinder 44 passes through the bottom side of the recovery port 431, it can be scraped into the recovery cavity 41 by the recovery port 431, realizing the recovery of the excess glue waste.

[0027] In the present invention, the position of the mounting plate 2 is adjusted by the adjusting mechanism 3 to adjust the position of the bottom block 4, so that no matter where the dispensing head 14 moves, the flat laying groove 42 can pass through the coating path of the glue. The flat laying groove 42 can widen and thin the narrow and thick glue, increase the contact surface between the glue and the decorative sticker, improve the adhesion between the decorative sticker and the box board, and at the same time can make the decorative sticker flatly laid on the box board, improve the surface flatness, greatly reduce the occurrence of edge glue overflow, and through the rotating cylinder 44, utilizing the viscosity of the glue, the excess glue waste can also be recovered into the recovery cavity 41, realizing the full utilization of the glue and being beneficial to reducing the waste of the glue.

[0028] Preferably, a camshaft 45 is provided on one side of the recovery tank 43. A convex portion 451 is provided on the side of the camshaft 45 facing the recovery port 431. A rotating hole 432 is formed on the other side of the recovery tank 43. One end of the rotating cylinder 44 is provided with a rotating shaft 441 and the other end is provided with a through port 442 for the camshaft 45 to penetrate. The camshaft 45 is located inside the rotating cylinder 44. The rotating shaft 441 is rotatably installed in the rotating hole 432. A plurality of glue storage grooves 443 are circumferentially and evenly distributed on the rotating cylinder 44. A push block 444 is slidably installed in each glue storage groove 443, and the edge of the push block 444 should be fitted with the inner wall of the glue storage groove 443. The end of the push block 444 close to the inside of the rotating cylinder 44 is the inner end and the other end is the outer end. Support blocks are provided on both sides of the inner end of the push block 444. A second spring 445 is connected between the support block and the inner wall of the rotating cylinder 44. The second spring 445 can provide an elastic force to make the inner end of the push block 444 abut against the surface of the camshaft 45 and make the push block 444 retract into the glue storage groove 443, so that there is a distance between the outer end of the push block 444 and the edge of the slot opening of the glue storage groove 443, so that the glue storage groove 443 can store a certain amount of glue liquid additionally, improve the transfer amount of the glue liquid waste by the rotating cylinder 44. When the push block 444 reaches the recovery port 431 as the rotating cylinder 44 rotates, the convex portion 451 can push the outer end of the push block 444 to the edge of the slot opening of the glue storage groove 443, and then push the glue liquid in the glue storage groove 443 into the recovery cavity 41 through the recovery port 431. And the continuous rotation of the rotating cylinder 44 will scrape off the glue liquid on the surface of the rotating cylinder 44 and the outer end of the push block 444 at the recovery port 431, so that the rotating cylinder 44 can recycle and transfer the glue liquid waste subsequently.

[0029] Preferably, the outer end of the push block 444 is arc-shaped. When the outer end of the push block 444 is pushed to the edge of the slot opening of the glue storage groove 443, the outer end of the push block 444 can form a complete arc with the outer wall of the rotating cylinder 44, so that the recovery port 431 can fully scrape off the residual glue liquid at the outer end of the push block 444.

[0030] Further, the driving mechanism 5 includes a second gear 51, a third gear 52 and two roller groups 53. Each roller group 53 includes three rollers 531. The two roller groups 53 are symmetrically installed on both sides of the bottom block 4. Among the three rollers 531 of each roller group 53, two rollers 531 have the same height and the other roller 531 is located at the highest position. A belt 54 is disposed around the outside of each roller group 53. It should be noted that the bottom surface of the belt 54 should slightly protrude from the bottom of the bottom block 4 so that it can abut against the surface of the packaging box board. The second gear 51 is installed on the roller 531 at the highest position in one of the roller groups 53, and the third gear 52 meshing with the second gear 51 is installed on the rotating shaft. When the movable seat 12 moves downward to make the dispensing head 14 approach the surface of the packaging box board, under the elastic force of the first spring 21, the belt 54 will abut against the board surface. As the dispensing head 14 moves, the belt 54 will also roll on the board surface and drive each roller 531 to rotate. Furthermore, the rotating cylinder 44 is driven to rotate through the meshing of the second gear 51 and the third gear 52, realizing the transfer and recovery of the waste glue liquid while performing the dispensing operation, enabling the dispensing and the spreading of the glue liquid to be carried out in coordination, improving the dispensing efficiency. Moreover, the belt 54 rolling on the board surface is also beneficial to reducing the frictional resistance between the bottom block 4 and the board.

[0031] In an embodiment, one end of the rotating shaft 441 away from the rotating cylinder 44 is located outside the bottom block 4 and is provided with a driving disk 446. A wave track 447 is disposed around the rotating shaft 441 on the side of the driving disk 446 facing the bottom block 4. An insertion groove 433 is formed in the inner wall of the recovery groove 43 away from the rotating shaft 441, and a through groove 434 is formed in the inner wall of the other side. The insertion groove 433 and the through groove 434 are coaxially arranged and are located on the side of the recovery groove 43 close to the dispensing head 14. A smoothing rod 435 is slidably inserted through the through groove 434. One end of the smoothing rod 435 penetrates into the insertion groove 433, and a third spring 436 is connected between the smoothing rod 435 and the insertion groove 433. The third spring 436 can provide an elastic force to make the other end of the smoothing rod 435 abut against the wave track 447. During the dispensing operation, the rotating cylinder 44 rotates under the drive of the driving mechanism 5 to recover the waste glue liquid. The driving disk 446 rotates with the rotating cylinder 44. The uneven surface of the wave track 447 will continuously pass by the end of the smoothing rod 435. With the elastic force of the third spring 436, the smoothing rod 435 can be continuously pushed back and forth. When the smoothing rod 435 passes through the narrow and thick glue liquid, the glue liquid can be spread to both sides, enabling the glue liquid to be widened and thinned more quickly by the spreading groove 42 subsequently.

[0032] Due to the limited space of the recovery chamber 41, in order to increase the accommodation space for the recovered glue liquid and facilitate subsequent utilization, in one embodiment, a glue storage mechanism 6 is further included, which includes a glue storage bin 61, a piston rod 62 and a connecting pipe 63. The glue storage bin 61 is arranged on the mounting plate 2. The piston rod 62 passes through the bottom of the glue storage bin 61 and its bottom end is connected to the lower pressing plate 22. A piston piece is arranged at the top end of the piston rod 62 inside the glue storage bin 61. Two one-way valves 611 with opposite directions are respectively arranged at the top of the glue storage bin 61. One one-way valve 611 only allows substances to enter the glue storage bin 61, and the other one-way valve 611 only allows substances to discharge from the glue storage bin 61. One end of the connecting pipe 63 is connected to the one-way valve 611 that only allows substances to enter the glue storage bin 61, and the other end is communicated with the recovery chamber 41. Whenever the dispensing head 14 completes a dispensing operation, the movable seat 12 will move upward to perform dispensing at another position of the gift box board. When the movable seat 12 drives the dispensing head 14 to move upward, the first spring 21 can push the lower pressing plate 22 to move away from the mounting plate 2 again, and drive the piston rod 62 to be withdrawn from the glue storage bin 61. Thus, a negative pressure is formed inside the glue storage bin 61, and the glue liquid in the recovery chamber 41 will be absorbed into the glue storage bin 61 through the connecting pipe 63. When the dispensing head 14 performs the dispensing operation at the next position, the movable seat 12 will move downward and press the lower pressing plate 22 against the mounting plate 2, so that the piston rod 62 is inserted upward into the glue storage bin 61, and the gas in the glue storage bin 61 is discharged through the one-way valve 611 that only allows substances to discharge from the glue storage bin 61 to maintain the internal pressure stable. By using the up and down movement of the movable seat 12 during each dispensing operation and cooperating with the first spring 21, the lower pressing plate 22 can periodically approach and move away from the mounting plate 2, and further drive the piston rod 62 to move with the start and end of dispensing. Gas in the glue storage bin 61 is discharged in advance at the start of each dispensing, and the glue liquid waste in the recovery chamber 41 is absorbed after each dispensing ends, so that enough recovery space can be left in the recovery chamber 41 at the start of each dispensing, and finally the glue liquid waste is concentrated and collected in the glue storage bin 61.

[0033] Preferably, a threaded port 46 communicated with the recovery chamber 41 is arranged on the outside of the bottom block 4, and the end of the connecting pipe 63 is threadedly connected to the threaded port 46, which is beneficial to cleaning the recovery chamber 41 after the dispensing operation is completed.

[0034] Preferably, the glue storage bin 61 is detachably connected to the mounting plate 2, specifically by conventional methods such as plugging or bolt connection, so as to disassemble and assemble the glue storage bin 61, and thus facilitate the recovery of the glue liquid waste.

[0035] Preferably, a heating wire (not shown in the figure) is arranged on the glue storage bin 61 to prevent the glue liquid from solidifying. Of course, it should be noted that the glue liquid selected for the dispensing operation is usually hot melt glue, which still has viscosity after solidifying and then melting, so it can be recycled.

[0036] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Although the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments with equivalent changes within the scope of the technical solution of the present invention. However, as long as it does not depart from the content of the technical solution of the present invention, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
