Description

Technical Field

[0001] The present application relates to the technical field of packaging product coating, and in particular to a packaging product processing roller coating device. Background Art

[0002] Packaging products refer to various containers and materials used to protect, carry, store and transport goods. They play an important role in modern business and daily life. They not only protect products from damage, but also help to enhance the market appeal of products. Roll-on coating of packaging products is a common surface treatment technology, which is usually used to improve the waterproofness, wear resistance, aesthetics or provide specific functions of packaging materials.

[0003] For example, a packaging product processing glue rolling device with publication number CN218308888U relates to the technical field of packaging box processing, and includes a support frame; a glue box is arranged at the upper end of the glue rolling frame, a stirring assembly is arranged inside the glue box, a glue outlet strip is connected to the lower end of the glue box, a first glue coating roller is arranged at the lower end of the glue rolling frame corresponding to the glue outlet strip, the left and right sides of the first glue coating roller are respectively rotatably connected with a connecting frame, and a driving motor is arranged at one end of the first glue coating roller; a plurality of second glue coating rollers are arranged on one side of the first glue coating roller relative to the movement direction of the transmission belt assembly, and the beneficial effect of the prior art is: by arranging the first glue coating roller and the second glue coating roller, the glue in the glue box is sprayed from the glue outlet strip to the surface of the first glue coating roller, and then the first glue coating roller is used to apply the glue on the packaging cardboard located on the conveyor belt assembly, and then the plurality of second glue coating rollers are used to evenly apply the glue on the packaging cardboard, thereby improving the work efficiency.

[0004] However, the above-mentioned prior art still has some defects when coating packaging products: 1. The glue in the glue box in the above-mentioned patent application will cause uneven distribution of glue in the glue strip when entering the glue strip, that is, the glue is the most at the connection between the glue strip and the glue box, and the glue gradually decreases from there to both sides of the glue strip, which will cause uneven distribution of glue sprayed on the first glue coating roller from the glue strip. When the first glue coating roller coats the packaging product, it will cause the packaging product to be unable to be evenly coated with glue, thereby reducing the finished product rate of the packaging product and increasing the cost of the device.

[0005] 2. In the above patent application, when the glue box conveys glue to the glue discharging strip, the glue output cannot be effectively controlled, so a first scraper and a first collecting box are set. However, after the first scraper scrapes off the excess glue on the first glue coating roller, there may be insufficient glue when applying glue to the packaging product, which may cause the packaging product to be unable to be effectively bonded, thereby reducing the packaging success rate.

[0006] Based on this, and in accordance with the above-mentioned viewpoints, the existing technology for rolling glue coating on packaging products still has room for improvement. Summary of the invention

DETAILED DESCRIPTION

[0044] The following is combined with Figures 1 to 13 This application is described in further detail.

[0045] The embodiment of the present application discloses a packaging product processing roller glue coating equipment, which can ensure that the glue coating roller can evenly apply glue on the packaging product when applying glue, thereby avoiding a reduction in the packaging success rate of the packaging product due to uneven glue application.

[0046] Embodiment 1:

[0047] Reference Figure 1 and Figure 2 A packaging product processing glue rolling and coating equipment includes a conveyor 1, a glue rolling device 2 for coating glue is provided on the conveyor 1, the glue rolling device 2 includes a height adjustment mechanism 3 arranged on both sides of the conveyor 1, a plurality of glue coating rollers 4 are installed between the height adjustment mechanisms 3, and a plurality of glue discharging mechanisms 5 evenly distributed are provided on the circumferential surface of the glue coating roller 4 along its length direction.

[0048] The glue discharging mechanism 5 includes a plurality of glue discharging boxes 51 circumferentially arranged on the glue coating roller 4. The glue discharging box 51 is provided with a plurality of glue outlets 52 on the side away from the corresponding glue coating roller 4. A telescopic spring rod 53 is installed between the glue discharging box 51 and the glue coating roller 4. The glue coating roller 4 is provided with a glue feeding assembly corresponding to the telescopic spring rod 53 one by one to provide glue for the glue discharging box 51.

[0049] The outer wall of the glue roller 4 is also provided with a first glue sponge 6 and a cleaning mechanism 7 corresponding to each group of glue discharging mechanisms 5. The first glue sponge 6 is used to apply glue on the packaging product, and the cleaning mechanism 7 is used to clean the inner wall of the glue roller 4.

[0050] Among them, both ends of the glue coating roller 4 are equipped with glue injection ports 42 and water injection ports 43, and both the glue injection ports 42 and water injection ports 43 are equipped with one-way valves (not shown in the figure), and the movement direction of the glue coating roller 4 is opposite to the movement direction of the conveyor 1, so as to better glue the packaging products. In the specific implementation process, first, glue is injected into the glue coating roller 4 through the glue injection port 42, and the glue coating roller 4 is adjusted to the height of the packaging product thickness required for production through the height adjustment mechanism 3. When the packaging product moves to the position of the glue coating roller 4 with the conveyor 1, the glue discharge mechanism 5 will discharge the glue in the glue coating roller 4 onto the packaging product while squeezing the packaging product.

[0051] Among them, each group of adjacent glue discharging mechanisms 5, first glue coating sponges 6 and cleaning mechanisms 7 on the outer wall of the glue coating roller 4 is a complete glue rolling and coating process. During the specific implementation process, when the glue coating roller 4 rotates, the glue discharging mechanism 5 and the cleaning mechanism 7 inside the glue coating roller 4 can stir the glue, thereby preventing the glue from solidifying. Along the rotation direction of the glue coating roller 4, after each group of glue discharging mechanisms 5 discharges the glue onto the packaging product, the first glue coating sponge 6 begins to apply the glue on the packaging product. Because there are multiple glue discharging mechanisms 5 evenly arranged along the length direction of the glue coating roller 4, the glue discharged from each group of glue discharging mechanisms 5 onto the packaging product is also evenly distributed, and then the first glue coating sponge 6 applies the glue, so that the glue can be evenly applied on the surface of the packaging product, thereby improving the success rate of packaging. At the same time, multiple glue coating rollers 4 discharge and apply glue to the packaging product along the movement direction of the conveyor 1, which can further ensure the uniformity of the glue on the packaging product.

[0052] After the glue coating work of the packaging product is completed, water is injected into the glue coating roller 4 through the water injection port 43, and the cleaning mechanism 7 inside the glue coating roller 4 can clean the inner wall of the glue coating roller 4. At the same time, the water in the glue coating roller 4 can also be discharged to the conveyor 1 through the glue discharge mechanism 5, thereby cleaning the conveyor 1 to prevent the residual glue in the equipment from solidifying and affecting the next glue rolling and coating process.

[0053] Reference Figure 4 The glue discharging mechanism 5 includes a plurality of glue discharging boxes 51 circumferentially arranged on the glue coating roller 4. The glue discharging box 51 is provided with a plurality of glue outlets 52 on one side away from the corresponding glue coating roller 4 to discharge the glue in the glue discharging box 51 onto the packaging product.

[0054] A telescopic spring rod 53 is installed between the glue discharging box 51 and the glue coating roller 4 .

[0055] Among them, each group of glue discharging mechanism 5, first glue coating sponge 6 and cleaning mechanism 7 outside the glue coating roller 4 are slidably connected to each other, and one end of the telescopic spring rod 53 is installed on the glue discharging box 51, and the other end of the telescopic spring rod 53 is installed on the glue coating roller 4. During the specific implementation process, when the glue discharging mechanism 5 squeezes the packaging product, the reaction force of the packaging product causes the glue discharging box 51 and the telescopic spring rod 53 to slide radially inward along the glue coating roller 4. At this time, the glue enters the glue discharging box 51 and is discharged onto the packaging product through the glue outlet 52. After the glue discharging box 51 leaves the packaging product along the rotation direction of the glue coating roller 4, the telescopic spring rod 53 resets the glue discharging box 51, and the first glue coating sponge 6 adjacent to the glue discharging box 51 and the cleaning mechanism 7 adjacent to the first glue coating sponge 6 begin to apply glue on the packaging product, so that the glue can be evenly applied to the packaging product, thereby improving the packaging success rate.

[0056] Reference Figure 4 , Figure 5 and Figure 6 In order to allow the glue to enter the glue box 51 from the glue coating roller 4 when the glue box 51 contracts radially inwardly along the glue coating roller 4, the glue feeding assembly of the present invention includes a glue feeding rod 54, and a rotating rod 41 is installed in the center of the glue coating roller 4, and a glue feeding rod 54 is installed on the side of the glue box 51 close to the rotating rod 41. The glue in the glue coating roller 4 can enter the glue box 51 through the glue feeding rod 54, and the glue feeding rod 54 is slidably arranged on the glue coating roller 4 and is connected to the glue box 51, and the part of the glue feeding rod 54 outside the glue coating roller 4 is located in the telescopic spring rod 53.

[0057] The glue feeding rod 54 is provided with a plurality of glue feeding ports 55 outside the glue coating roller 4 and close to the glue coating roller 4 , and a glue blocking plate 56 is installed between the glue feeding port 55 and the glue coating roller 4 .

[0058] A limiting ring 57 is provided on the glue feeding rod 54 at a portion inside the glue coating roller 4 close to the inner wall of the glue coating roller 4 to prevent the glue feeding rod 54 from excessively sliding outward along the radial direction of the glue coating roller 4 .

[0059] Among them, a plurality of glue discharge ports 514 are arranged between the connection between the telescopic spring rod 53 and the glue outlet box 51 and the connection between the glue feed rod 54 and the glue outlet box 51, and the connection between the telescopic spring rod 53, the glue outlet box 51 and the glue coating roller 4 are all sealed. During the specific implementation process, when the glue outlet box 51 contracts radially inward along the glue coating roller 4, the glue feed rod 54 is driven to slide toward the inside of the glue coating roller 4 along its axial direction, so that the glue feed port 55 enters the inside of the glue coating roller 4, and the glue in the glue coating roller 4 enters the glue feed port 55 and enters the glue outlet box 51 under the action of gravity, and is finally discharged onto the packaging product through the glue outlet 52 on the glue outlet box 51.

[0060] After the glue discharge box 51 leaves the packaged product, under the action of the telescopic spring rod 53, the glue discharge box 51 and the glue feeding rod 54 begin to reset. When the limiting ring 57 inside the glue coating roller 4 of the glue feeding rod 54 contacts the inner wall of the glue coating roller 4, the glue feeding rod 54 and the glue discharge box 51 stop sliding, that is, the two are successfully reset. At this time, the glue remaining in the glue discharge box 51 begins to flow back under the action of gravity as the glue discharge box 51 rotates. A part of the glue flows into the telescopic spring rod 53 from the glue inlet 55 during the backflow process, and re-enters the glue discharge box 51 through the glue discharge port 514 under the action of gravity after the glue discharge box 51 rotates for a cycle and is discharged. The other part of the glue stops flowing back due to the obstruction of the glue blocking plate 56, and directly enters the glue discharge box 51 under the action of gravity after the glue discharge box 51 rotates for a cycle and is discharged.

[0061] Reference Figure 5 and Figure 7 In order to enable the glue discharging mechanism 5 to stir the glue inside the glue coating roller 4 while discharging the glue to prevent the glue from solidifying, a sliding block 58 is provided on the inner wall of the end of the glue feeding rod 54 away from the glue discharging box 51.

[0062] The glue discharging mechanism 5 includes a central axis rod 59 rotatably mounted on the rotating rod 41 through a bearing. An end of the central axis rod 59 away from the rotating rod 41 is provided with an M-shaped sliding groove 510 surrounding the central axis rod 59. The sliding groove 510 is slidably connected to the sliding block 58.

[0063] Among them, one end of the central axis rod 59 away from the rotating rod 41 is sleeved in the end of the glue feeding rod 54 away from the liquid outlet box. During the specific implementation process, when the glue feeding rod 54 slides back and forth on the glue coating roller 4 along with the extension and retraction of the glue outlet box 51, the sliding block 58 also slides back and forth in the sliding groove 510 of the M-shaped structure along with the glue feeding rod 54. Since the sliding block 58 is fixed on the glue feeding rod 54 and the central axis rod 59 is rotatably installed on the rotating rod 41 through a bearing, when the sliding block 58 slides in the sliding groove 510 of the M-shaped structure, the central axis rod 59 can rotate, and then the glue can be stirred to avoid the glue solidification causing the glue outlet mechanism 5 to be unable to smoothly discharge glue, thereby reducing the packaging success rate.

[0064] Reference Figure 5 In order to enable the central axis rod 59 to produce sufficient stirring effect when rotating, a first rotating ring 511 is installed on the portion of the central axis rod 59 close to the rotating rod 41, and a second rotating ring 512 is sleeved on the portion of the glue feeding rod 54 close to the limiting ring 57 inside the glue coating roller 4, and a plurality of spiral blades 513 are installed between the two rotating rings.

[0065] Among them, the first rotating ring 511 on the central axis rod 59 is fixedly connected to the central axis rod 59, the second rotating ring 512 on the glue feeding rod 54 is sleeved on the glue feeding rod 54, and the multiple spiral blades 513 between the first rotating ring 511 and the second rotating ring 512 have a certain supporting effect, so that the relative position between the first rotating ring 511 and the second rotating ring 512 remains unchanged. During the specific implementation process, the central axis rod 59 drives the first rotating ring 511 to rotate when it rotates, and then synchronously drives the spiral blades 513 and the second rotating ring 512 to rotate, so that the spiral blades 513 stir the glue to avoid the influence of glue solidification on glue discharge and brushing.

[0066] Reference Figure 3 and Figure 8 The cleaning mechanism 7 includes a gear box 71 arranged on either end of the glue coating roller 4. The gear box 71 is provided with a second glue coating sponge 72 radially outwardly along the glue coating roller 4 to continue to apply glue that is not evenly coated on the first glue coating sponge 6. A rotating shaft 73 is rotatably installed in the middle of the gear box 71 along the axial direction of the rotating rod 41 through a bearing, and a plurality of first linked bevel gears 74 are installed on the outer wall of the rotating shaft 73 in the gear box 71.

[0067] During the specific implementation process, after the first glue sponge 6 has applied glue on the packaging product, the second glue sponge 72 adjacent to the first glue sponge 6 continues to apply the unapplied glue to ensure that the glue discharged from the liquid outlet box can be evenly applied on the packaging product, thereby improving the success rate of packaging.

[0068] Reference Figure 8 and Fig. 9In order to enable the cleaning mechanism 7 to clean the inner wall of the glue coating roller 4, a plurality of linkage rods 75 are provided in the gear box 71 radially inwardly along the glue coating roller 4. Each linkage rod 75 is provided with a second linkage bevel gear 76 meshing with the corresponding first linkage bevel gear 74 at one end away from the rotating rod 41. The linkage rod 75 passes through the glue coating roller 4, and a linkage plate 77 is provided at one end of the linkage rod 75 away from the second linkage bevel gear 76.

[0069] The part of the linkage rod 75 close to the inner wall of the glue coating roller 4 is provided with a plurality of cleaning sponges 78 evenly distributed along the axial direction of the linkage rod 75, which can clean the inner wall of the glue coating roller 4, and a plurality of elastic telescopic rods 79 corresponding to the cleaning sponges 78 are installed on the linkage plate 77, and the telescopic ends of the elastic telescopic rods 79 are connected to the cleaning sponges 78.

[0070] The linkage rod 75 is rotatably mounted on the glue coating roller 4 through a bearing, and adjacent linkage plates 77 will not collide with each other during rotation, nor will they interfere with the rotation of the central axis rod 59. At the same time, when the cleaning sponges 78 corresponding to the multiple linkage plates 77 on the same circumferential surface of the glue coating roller 4 are perpendicular to the axial direction of the glue coating roller 4, a circular ring structure can be formed between the cleaning sponges 78, thereby achieving comprehensive cleaning of the inner wall of the glue coating roller 4. In the specific implementation process, when the rotating shaft 73 rotates, it will drive the first linkage bevel gear 74 to rotate, and the first linkage bevel gear 74 will drive the second linkage bevel gear 76 to rotate through the bevel gear meshing transmission mode, and the second linkage bevel gear 76 will further drive the linkage rod 75 and the linkage bevel gear 76. The movable plate 77 rotates, and since the cleaning sponges 78 are connected to the linkage plate 77 through the elastic telescopic rod 79, when the linkage plate 77 rotates, the elastic telescopic rod 79 and the cleaning sponge 78 will be driven to rotate synchronously. Under the action of the elastic telescopic rod 79, the cleaning sponge 78 can always be in contact with the inner wall of the glue coating roller 4. When there is glue inside the glue coating roller 4, the combination of the linkage plate 77, the elastic telescopic rod 79 and the cleaning sponge 78 can stir the glue during rotation to prevent the glue from solidifying. When there is clear water inside the glue coating roller 4, the combination can clean the inner wall of the glue coating roller 4 during rotation to ensure that when it is used next time, no condensed glue will interfere with the glue dispensing process and reduce the packaging efficiency.

[0071] During the specific implementation process, the rotating shaft 73 drives the first linkage bevel gear 74 to rotate. Under the meshing transmission of the second linkage bevel gear 76 of the first linkage bevel gear 74, the linkage rod 75 and the linkage plate 77 start to rotate and drive the elastic telescopic rod 79 and the cleaning sponge 78 to rotate, so that the combination of the linkage plate 77, the elastic telescopic rod 79 and the cleaning sponge 78 can not only stir the glue, but also clean the inner wall of the glue coating roller 4 when the inside of the glue coating roller 4 is filled with clean water.

[0072] Embodiment 2:

[0073] Reference Fig.11 In order to enable the equipment to adjust the height to cope with packaging products of different thicknesses, the height adjustment mechanism 3 includes a lifting plate 31, and the lifting plate 31 is slidably penetrated by two limit rods 32, and the bottom of the limit rod 32 is installed on the conveyor 1; the rotating rod 41 is rotatably penetrated on the lifting plate 31, and one end of the rotating rod 41 on one of the glue coating rollers 4 is connected to a driving motor 8.

[0074] A threaded rod 33 is threadedly penetrated through the middle of the lifting plate 31 .

[0075] The unthreaded portion at the bottom of the threaded rod 33 is rotatably mounted on the conveyor 1 via a bearing, a limit plate 34 is installed on the top of the two limit rods 32, the unthreaded portion at the top of the threaded rod 33 passes through the limit plate 34, and a rotating handle 35 is provided at the end of the threaded rod 33 away from the conveyor 1.

[0076] Reference Fig.10 In order to rotate the rotating shaft 73 , driving bevel gears 710 are installed at both ends of the rotating shaft 73 , and a rack plate 711 meshing with the driving bevel gear 710 is installed on the side of the lifting plate 31 close to the glue coating roller 4 .

[0077] The lifting plate 31 is slidably connected with the limit rod 32, and the lifting plate 31 is installed with a support plate supporting the driving motor 8, so that the driving motor 8 can be lifted and lowered together with the lifting plate 31. In the specific implementation process, the threaded rod 33 is driven to rotate by rotating the rotating handle 35. Since the lifting plate 31 and the threaded rod 33 are rotatably connected by threads, and the limit rods 32 at both ends of the lifting plate 31 can limit the position of the lifting plate 31, it can be ensured that when the threaded rod 33 rotates, the lifting plate 31 does not rotate. Therefore, when the rotating handle 35 is rotated, the lifting plate 31 and the threaded rod 33 are lifted and lowered by thread rotation, and then the lifting and lowering of the lifting plate 31 can be controlled by controlling the rotation direction of the rotating handle 35. At the same time, the limit plate 34 can ensure that the lifting plate 31 is lifted and lowered within a certain height range. Then, when facing packaging products with different thicknesses, the lifting plate 31 drives the glue coating roller 4 to reach a specified height by rotating the rotating handle 35, thereby realizing the glue dispensing and coating of the packaging products.

[0078] In addition, when the glue coating roller 4 rotates under the drive of the driving motor 8, the driving bevel gears 710 on both sides of the gear box 71 are meshed and transmitted with the rack plate 711, so that the rotating shaft 73 can drive the first linkage bevel gear 74 to rotate, thereby enabling the cleaning mechanism 7 to operate.

[0079] Reference Fig.12 In order to realize the rotation of the multiple glue coating rollers 4, the rotating rod 41 that passes through the outside of the lifting plate 31 is provided with a sprocket 36, and the sprockets 36 are connected by a chain 37.

[0080] Among them, the rotating rod 41 is penetrated through the lifting plate 31 and is rotatably installed with the lifting plate 31 through a bearing. During the specific implementation process, when the driving motor 8 drives any rotating rod 41 to rotate, the sprocket 36 on the rotating rod 41 rotates synchronously, and the sprockets 36 located on the same side of the conveyor 1 are connected by a chain 37, thereby achieving the goal of driving multiple rotating rods 41 to rotate by driving one rotating rod 41 to rotate.

[0081] Reference Fig.13 A rubber scraper 9 is provided on the bottom surface of the unloading end of the conveyor 1 along the moving direction of the conveyor 1. The rubber scraper 9 is slidably connected to the conveyor 1. A material receiving box 91 is provided at the end of the rubber scraper 9 away from the conveyor 1. The material receiving box 91 is fixedly connected to the conveyor 1.

[0082] When the glue coating roller 4 is applying glue to the packaging products, some glue may be attached to the conveyor 1. A scraper 9 is arranged at the bottom of the unloading end of the conveyor 1 to scrape off the glue attached to the conveyor 1. The scraped glue flows into the receiving box 91 below the scraper 9, avoiding the waste of glue and ensuring the flatness and tidiness of the conveyor 1.

[0083] When all the packaging products on the conveyor 1 are glued, and the equipment is cleaned, all parts inside the equipment stop working, and the glued packaging products are collected and kept for use in subsequent processes.

[0084] The implementation principle of the present invention is:

[0085] 1: When the glue discharging mechanism 5 squeezes the packaged product, the reaction force of the packaged product causes the glue discharging box 51 and the telescopic spring rod 53 to slide radially inward along the glue coating roller 4. At this time, the glue enters the glue discharging box 51 and is discharged onto the packaged product through the glue outlet 52. After the glue discharging box 51 leaves the packaged product along the rotation direction of the glue coating roller 4, the telescopic spring rod 53 resets the glue discharging box 51, and the first glue coating sponge 6 adjacent to the glue discharging box 51 and the cleaning mechanism 7 adjacent to the first glue coating sponge 6 begin to apply glue on the packaged product, so that the glue can be evenly applied to the packaged product, thereby improving the packaging success rate.

[0086] 2: When the glue coating roller 4 rotates, the glue discharging mechanism 5 and the cleaning mechanism 7 inside the glue coating roller 4 can stir the glue to prevent the glue from solidifying. Along the rotation direction of the glue coating roller 4, after each group of glue discharging mechanisms 5 discharges the glue onto the packaged product, the first glue coating sponge 6 begins to apply the glue on the packaged product. Because there are multiple glue discharging mechanisms 5 evenly arranged along the length direction of the glue coating roller 4, the glue discharged by each group of glue discharging mechanisms 5 onto the packaged product is also evenly distributed. Then the first glue coating sponge 6 applies the glue, so that the glue can be evenly applied to the surface of the packaged product, thereby improving the success rate of packaging.

[0087] 3: After the glue coating work of the packaging product is completed, water is injected into the glue coating roller 4 through the water injection port 43, and the cleaning mechanism 7 inside the glue coating roller 4 can clean the inner wall of the glue coating roller 4. At the same time, the water in the glue coating roller 4 can also be discharged to the conveyor 1 through the glue discharge mechanism 5, thereby cleaning the conveyor 1 to prevent the residual glue in the equipment from solidifying and affecting the next glue rolling and coating process.

[0088] The embodiments of this specific implementation method are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, all equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
