Description

Technical Field

[0001] This invention relates to the field of adhesive scraping technology, and in particular to a multifunctional edge adhesive scraping device and its usage method. Background Technology

[0002] Packaging cardboard needs to be bonded during the production process. During bonding, glue needs to be applied to both sides of the cardboard to improve the adhesion. When glue is applied to both sides of the cardboard, the adhesive force between the cardboards is significantly enhanced. This ensures that the cardboard will not easily fall apart or shift during use, thus ensuring that the overall structure of the packaging is more robust and less prone to deformation or breakage.

[0003] The patent with publication number CN115871276A discloses a corrugated cardboard box glue scraping device that can evenly spread the glue gathered on the side of the triangular scraper according to the thickness of the glue gap. The device can also perform glue suction operation in the middle and both ends of the triangular scraper by the suction hole on the triangular scraper to cover the excess glue, thus avoiding glue accumulation.

[0004] However, existing technologies still have the following drawbacks:

[0005] The aforementioned device can only absorb excess glue during edge application, thus removing it. However, it cannot reuse the glue in real time. Glue is used to join different parts during cardboard manufacturing, requiring application to both sides and the sidewalls. Failure to cover and coat the sidewalls prevents them from connecting with other cardboard sections, affecting the strength and stability of the edges and the overall structure. Furthermore, the inability to recycle excess glue during edge removal reduces its utilization efficiency.

[0006] Therefore, after the cardboard is manufactured, a squeegee is used to apply glue to the edges and corners to increase its bonding strength and stability. Summary of the Invention

[0007] In view of the problem that existing technology cannot directly apply glue to the side wall of cardboard when scraping glue at the edge, resulting in low glue utilization efficiency, a multifunctional edge glue scraping device and its usage method are proposed.

[0008] The purpose is to allow the overflowing glue to be directly and evenly applied to the side wall of the cardboard when scraping the edge glue, which improves the stability of the cardboard during assembly and bonding, and also increases the utilization efficiency of the overflowing glue.

[0009] The technical solution of the present invention is a multifunctional edge scraping device, including a scraping component;

[0010] The scraping component includes a scraping assembly, a dispensing assembly disposed on one side of the scraping assembly, and a rolling assembly disposed on the bottom side of the scraping assembly.

[0011] A glue-applying component is provided on one side of the glue-scraping component. The glue-applying component includes a glue-applying component provided on one side of the glue-dispensing component and compression components symmetrically provided on both sides of the glue-applying component.

[0012] The scraper assembly includes two scraper chambers symmetrically arranged and connected to each other, push grooves symmetrically arranged on the side walls of the two scraper chambers, a raised block between the two scraper chambers, scraper edges symmetrically opened at the bottom edges of the two scraper chambers, scraper strips symmetrically arranged on both sides of the raised block, and an exhaust hole opened in the middle of one side of the two scraper chambers, with the scraper strips fitting the edge of the scraper edge.

[0013] The scraper is used to scrape the excess glue on both sides of the cardboard edge, and the applicator is used to apply the glue scraped by the scraper to the side of the cardboard. The scraper and applicator together form an arched shape.

[0014] By adopting the above technical solution, a scraping component is set to scrape the glue overflowing from the side wall of the cardboard, and the scraped glue is then applied to the side of the cardboard by a glue applicator. This not only cleans up the glue overflowing from the side of the cardboard, but also allows the scraped glue to be applied back to the side of the cardboard, improving the utilization rate of the overflowing glue and avoiding waste of glue overflowing from the side of the cardboard. During the application of glue, the glue is scraped by the glue scraper. The rubber material of the glue scraper prevents it from squeezing the sides of the cardboard and causing deformation. The glue scraper moves along the side edge of the cardboard, bending in the direction of scraping. When a thick layer of glue overflows, the glue scraper can push it out and flatten it, allowing the glue to gradually enter the glue collection bin. This prevents all the glue from entering and causing accumulation and blockage at the glue collection bin opening, allowing the glue to enter the glue collection bin quickly. The scraped glue, under the action of the raised blocks, enters from the glue collection bins on both sides, preventing the glue entering from the sides from being squeezed into the middle of the two glue collection bins, causing glue to stagnate and accumulate, and preventing the glue in the middle from smoothly entering the glue application component. This diversion of glue from both sides improves the utilization rate of the glue. Furthermore, because the glue is continuously squeezed into the glue-scraping chamber during the scraping process, overflowing glue of different thicknesses is collected in the glue-scraping chamber. When thicker glue is scraped in, it creates a relatively closed state inside the glue-scraping chamber, allowing space between the glue being squeezed in. The venting holes allow air to be expelled when glue of different thicknesses is squeezed into the glue-scraping chamber, ensuring that glue is squeezed out evenly at the coating parts. This results in consistent glue application on the sides of the cardboard, improving the quality of the cardboard side coating.

[0015] Furthermore, the two scraper bins are outwardly expanding, and the horizontal projection of the edge at the midpoint of the top of the two scraper bins is longer than the horizontal projection of the edge of the raised block.

[0016] By adopting the above technical solution, the outward expansion of the scraper canister allows the glue to enter along the inside of the scraper canister, making it easier for the glue to enter the scraper canister after being scraped up. In addition, the horizontal projection of the edge at the middle connection of the top of the two scraper canisters is longer than the horizontal projection of the edge of the raised block, which can prevent the glue from overflowing from the top of the scraper canister after entering it.

[0017] Furthermore, the angle between the squeegee strip and the squeegee edge and one side of the cardboard is 45 degrees, and the squeegee strip is made of rubber, with both the squeegee strip and the squeegee edge being inclined.

[0018] By employing the above technical solution, the glue on the edges of the cardboard can be uniformly scraped at a 45-degree angle. This facilitates the subsequent bonding of the cardboard edges while preventing excessive glue removal from the edges, which could reduce the adhesion between cardboard sections later. The inclined glue scraping strip and the scraping edge design prevent damage to the cardboard edges during glue scraping and also achieve a rapid glue scraping effect.

[0019] Furthermore, the glue dispensing assembly includes a glue outlet disposed on one side of the two glue scraping chambers, and the glue outlet is flat and disposed near the edge of the cardboard.

[0020] By adopting the above technical solution, the flat glue outlet allows the glue entering the glue tank to form a strip, which facilitates the glue application component and allows the glue to be evenly applied to the side wall of the cardboard.

[0021] Furthermore, the rolling assembly includes mounting blocks symmetrically arranged at the bottom of the two glue scraping chambers, a connecting rod arranged in the middle of the two mounting blocks, and a rotating roller arranged in the middle of the connecting rod.

[0022] By adopting the above technical solution, the rotation setting allows the glue applicator to move along the side wall of the cardboard when it is pushed, reducing the resistance during the movement of the device, and making the device arched, so that the glue entering the glue tube can flow towards the glue outlet, improving the fluidity of the glue.

[0023] Furthermore, the adhesive application assembly includes an adhesive application rod disposed at the middle position of the two compression components, an adhesive application roller disposed at the middle of the adhesive application rod, and adhesive application sheets disposed in a ring-shaped inclined array on the adhesive application roller, wherein the adhesive application sheets are made of rubber.

[0024] Using the above technical solution, during the glue application process, the glue roller and glue sheet are squeezed and driven to rotate, so that the glue sheet can scrape the glue from the glue outlet and apply the glue to the side wall of the cardboard, thus completing the function of applying the glue overflowing from the side of the cardboard to the side wall of the cardboard.

[0025] Furthermore, the coating rod is disposed on one side of the center of the coating roller, and the coating sheet includes a long sheet and a short sheet, with the circle formed at the edge of the coating sheet having the same center as the coating rod.

[0026] By adopting the above technical solution, the glue applicator is not located in the center of the glue applicator roller. This allows the long and short pieces to apply different amounts of glue from the glue outlet when the glue applicator roller rotates. This enables the glue applicator roller to apply glue of different thicknesses intermittently during rotation. Since the amount of glue overflowing from the cardboard surface during glue application is small, this allows a small amount of glue to be applied more evenly to the side wall of the cardboard, avoiding the situation where half of the side wall of the cardboard is covered with glue and the other half is not.

[0027] Furthermore, the coating sheet and coating roller are integrally positioned slightly below the center of the glue outlet, and the line connecting any two opposing coating strip sides in their cross-sectional direction is longer than the height of the glue outlet.

[0028] By adopting the above technical solution, this setting allows the coating sheet and coating roller to reset and block the glue outlet under the reset action of the compression component after the coating is finished, preventing dust and impurities from entering the outlet and causing blockage during subsequent use, thus improving the service life of the device.

[0029] Furthermore, the compression assembly includes a compression groove opened in one side of the glue dispensing assembly, a compression hole disposed in one side of the compression groove, a compression member disposed in the compression groove, a compression plate disposed in one side of the compression member, and a compression block disposed in one side of the compression plate, wherein one end of the glue dispensing rod passes through the compression hole and is rotatably connected to the middle of the compression block.

[0030] Using the above technical solution, when the coating roller moves on the side wall of the cardboard, the friction generated during the movement of the coating roller and coating sheet due to the squeezing of the coating roller and coating sheet causes the coating rod to squeeze the compression block and compression plate, thus compressing the compression components. This serves two purposes: first, it allows the coating roller to move away from the glue outlet during the coating process, allowing more glue to flow out and be easily scraped by the coating sheet to coat the side wall of the cardboard; second, when coating stops, the coating roller resets and drives the coating sheet to seal the glue outlet, preventing impurities from entering the glue scraping chamber.

[0031] Another objective of this invention is to provide a method of using a multifunctional edge glue scraping device, the purpose of which is to improve the utilization efficiency of the edge glue after scraping and enhance the strength and stability of the bonded cardboard.

[0032] To achieve the above objectives, the present invention provides the following technical solution: a method for using a multifunctional edge adhesive scraping device, comprising the following steps:

[0033] When applying glue, hold the glue applicator with your hand, press it against the side of the cardboard, and press the push groove to move the entire glue applicator along the side wall of the cardboard.

[0034] The rotating roller adheres to the side wall of the cardboard and rolls along the side wall of the cardboard;

[0035] The glue scraping strips on both sides scrape the overflowing glue on both sides of the cardboard. The glue is scraped up by the scraping strips and squeezed into the glue tank during the continuous scraping process. Then it is squeezed to flow to the glue outlet.

[0036] The glue-applying roller is squeezed and rotated, causing the glue-applying sheet to spread the glue onto the side wall of the cardboard.

[0037] Compared with the prior art, the present invention has the following beneficial effects:

[0038] 1. By setting up a glue scraper to scrape the glue overflowing from the side wall of the cardboard, and then applying the scraped glue to the side of the cardboard through a glue applicator, the glue overflowing from the side of the cardboard can be cleaned up and the scraped glue can be applied to the side of the cardboard again, which improves the utilization rate of the overflowing glue and avoids the waste of glue overflowing from the side of the cardboard.

[0039] 2. The designed scraper strips can first push and spread out any overflowing glue, allowing the glue to gradually enter the scraper compartment. This prevents all the glue from entering and causing accumulation and blockage at the scraper compartment opening. The glue scraped up is then directed by the raised blocks to enter the scraper compartments on both sides, avoiding glue retention and accumulation. This diverts the glue from both sides, improving glue utilization.

[0040] 3. The compression component allows the coating roller to move away from the glue outlet during the coating process, resulting in more glue flowing out and making it easier for the coating sheet to scrape it up and coat the side wall of the cardboard. When coating stops, the coating roller resets and drives the coating sheet to seal the glue outlet, preventing impurities from entering the glue bin and improving the service life of the device.

[0054] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0055] Example 1, referring to Figures 1-5 According to the first embodiment of the present invention, a multifunctional edge scraping device is provided, including a scraping component; the scraping component includes a scraping assembly 1, a dispensing assembly 2 installed on one side of the scraping assembly 1, and a rolling assembly 3 installed on the bottom side of the scraping assembly 1; a coating component is installed on one side of the scraping component, the coating component includes a coating assembly 4 installed on one side of the dispensing assembly 2, and compression assemblies 5 symmetrically installed on both sides of the coating assembly 4; the scraping assembly 1 includes two symmetrically installed scraping chambers 11, the two scraping chambers 11 are connected to each other, and are symmetrically opened on the sides of the two scraping chambers 11. The wall has a push groove 12, a raised block 13 fixedly connected between two glue scraping chambers 11, glue scraping edges 14 symmetrically opened at the bottom edges of the two glue scraping chambers 11, glue scraping strips 15 symmetrically fixedly connected on both sides of the raised block 13, and an exhaust hole 16 opened in the middle of one side of the two glue scraping chambers 11, with the glue scraping strip 15 fitting against the edge of the glue scraping edge 14; the glue scraping component is used to scrape the overflowing glue at both sides of the cardboard, and the glue application component is used to apply the glue scraped by the glue scraping component to the side of the cardboard. The glue scraping component and the glue application component together form an arched shape.

[0056] Specifically, by setting up a glue scraper to scrape the glue overflowing from the side wall of the cardboard, and then applying the scraped glue to the side of the cardboard through a glue applicator, the glue overflowing from the side of the cardboard can be cleaned up, and the scraped glue can be applied back to the side of the cardboard, which improves the utilization rate of the overflowing glue and avoids the waste of glue overflowing from the side of the cardboard. During the application of glue, the glue is scraped by the glue scraper 15. The rubber material of the glue scraper 15 prevents the glue from being squeezed against the side of the cardboard during the application process, thus avoiding deformation of the cardboard side. When scraping, the glue scraper 15 scrapes along the side edge of the cardboard. During the scraping process, the glue scraper 15 bends in the direction of scraping. When the overflowing glue is thick, the glue scraper 15 can first push the overflowing glue to flatten it, so that the glue can gradually enter the glue collection 11. This prevents all the glue from entering and causing the glue to accumulate and block the glue outlet 21, allowing the glue to enter the glue collection 11 quickly. The scraped glue enters from the glue collection 11 on both sides under the action of the raised block 13, preventing the glue entering from both sides from being squeezed into the middle of the two glue collection 11, causing the glue to stay and accumulate. This prevents the glue in the middle from smoothly entering the glue application part, thus diverting the glue on both sides and improving the utilization rate of the glue. Furthermore, since the glue is continuously squeezed into the glue-scraping chamber 11 during the scraping process, overflowing glue of different thicknesses is collected in the glue-scraping chamber 11. When a thicker glue is scraped in, it creates a relatively closed state inside the glue-scraping chamber 11, allowing space between the glue that is squeezed in. The vent 16 allows air to be expelled when glue of different thicknesses is squeezed into the glue-scraping chamber 11, ensuring that glue is squeezed out evenly at the coating part, resulting in consistent glue application on the side of the cardboard and improving the quality of the glue application on the side of the cardboard.

[0057] Reference Figure 1 , Figure 4 and Figure 5 The two glue scraping chambers 11 are expanded outwards, and the horizontal projection of the edge of the middle connection point at the top of the two glue scraping chambers 11 is longer than the horizontal projection of the edge of the raised block 13.

[0058] Specifically, the outward expansion of the scraper 11 allows the glue to enter along the inside of the scraper 11, making it easier for the glue to enter the scraper 11 after being scraped up. Furthermore, the horizontal projection of the edge at the connection between the tops of the two scraper 11 is longer than the horizontal projection of the edge of the raised block 13, which can prevent the glue from overflowing from the top of the scraper 11 after entering it.

[0059] Reference Figures 1-5 The angle between the squeegee strip 15 and the squeegee edge 14 and one side of the cardboard is 45 degrees, and the squeegee strip 15 is made of rubber. Both the squeegee strip 15 and the squeegee edge 14 are inclined.

[0060] Specifically, this allows the glue on the edges of the cardboard to be uniformly scraped at a 45-degree angle, which facilitates the later bonding of the cardboard edges and prevents excessive glue from being scraped away, thus reducing the adhesion between the cardboard pieces later. The inclined glue scraping strip 15 and glue scraping edge 14 can prevent damage to the edges of the cardboard during glue scraping and can also achieve a fast glue scraping effect.

[0061] Reference Figures 1-7 The glue dispensing assembly 2 includes a glue outlet 21 opened on one side of the two glue scraper bins 11, and the glue outlet 21 is flat and opened on the side close to the cardboard.

[0062] Specifically, the flat glue outlet 21 allows the glue entering the glue tank 11 to form a strip, which facilitates the glue application component 4 to apply the glue, so that the glue can be evenly applied to the side wall of the cardboard.

[0063] Reference Figures 1-8 The rolling assembly 3 includes mounting blocks 31 symmetrically fixedly connected to the bottom of the two scraper bins 11, a connecting rod 32 rotatably connected to the middle of the two mounting blocks 31, and a rotating roller 33 fixedly connected to the middle of the connecting rod 32.

[0064] Specifically, the rotating roller 33 allows the glue applicator to move along the side wall of the cardboard when it is pushed, reducing the resistance during the movement of the device and making the device arched, so that the glue entering the glue tube 11 can flow towards the glue outlet 21, improving the fluidity of the glue.

[0065] Example 2, refer to Figures 1-10 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the glue application assembly 4 includes a glue application rod 41 rotatably connected at the middle position of the two compression assemblies 5, a glue application roller 42 fixedly connected to the middle part of the glue application rod 41, and a glue application sheet 43 fixedly connected to the glue application roller 42 in a ring-shaped inclined array, and the glue application sheet 43 is made of rubber.

[0066] Specifically, during the glue application process, the glue application roller 42 and the glue application sheet 43 are squeezed and driven to rotate, so that the glue application sheet 43 can scrape the glue from the glue outlet 21 and apply the glue to the side wall of the cardboard, thus completing the function of applying the glue overflowing from the side of the cardboard to the side wall of the cardboard.

[0067] Reference Figure 10 The glue-applying rod 41 is fixedly connected to one side of the center of the glue-applying roller 42, and the glue-applying sheet 43 includes a long sheet 431 and a short sheet 432. The circle formed at the edge of the glue-applying sheet 43 is concentric with the glue-applying rod 41.

[0068] Specifically, the glue applicator 41 is not positioned at the center of the glue applicator roller 42, so that when the glue applicator roller 42 rotates, the long strip 431 and the short strip 432 apply different amounts of glue from the glue outlet 21. This allows the glue applicator roller 42 to intermittently apply glue of different thicknesses during rotation. Since the amount of glue overflowing from the cardboard surface during glue application is small, this allows a small amount of glue to be applied more evenly to the side wall of the cardboard, avoiding the situation where half of the side wall of the cardboard is coated with glue and the other half is not coated after the glue is scraped off.

[0069] Reference Figures 1-10 The coating sheet 43 and the coating roller 42 are installed as a whole in the lower middle part of the glue outlet 21, and the line connecting any two opposite sides of the coating strip in its cross-sectional direction is longer than the height of the glue outlet 21.

[0070] Specifically, this configuration allows the coating sheet 43 and coating roller 42 to reset and block the glue outlet 21 after the coating process is completed, under the reset action of the compression component 5. This prevents dust and impurities from entering the outlet and causing blockages during subsequent use, thus improving the service life of the device.

[0071] Reference Figures 1-11 The compression assembly 5 includes a compression groove 51 opened in one side of the glue dispensing assembly 2, a compression hole 52 opened in one side of the compression groove 51, a compression member 53 fixedly connected in the compression groove 51 (the compression member 53 can be a spring), a compression plate 54 fixedly connected in one side of the compression member 53, and a compression block 55 fixedly connected in one side of the compression plate 54. One end of the glue dispensing rod 41 passes through the compression hole 52 and is rotatably connected to the middle of the compression block 55.

[0072] Specifically, when the coating roller 42 moves on the side wall of the cardboard, the friction generated during the movement due to the compression of the coating roller 42 and the coating sheet 43 causes the coating rod 41 to squeeze the compression block 55 and the compression plate 54, thus compressing the compression component 53. This serves two purposes: first, it allows the coating roller 42 to move away from the glue outlet 21 during the coating process, allowing more glue to flow out and be easily scraped by the coating sheet 43 to coat the side wall of the cardboard; second, when coating stops, the coating roller 42 resets, causing the coating sheet 43 to seal the glue outlet 21, preventing impurities from entering the glue scraper 11. The remaining structure is the same as in Embodiment 1.

[0073] Example 3, referring to Figures 1-11 This is the third embodiment of the present invention, which differs from the second embodiment in that:

[0074] S1. When applying glue, hold the glue applicator with your hand, attach the glue applicator to the side of the cardboard, and press the push groove 12 to push the glue applicator to move on the side wall of the cardboard.

[0075] S2, Rotating roller 33 adheres to the side wall of the cardboard and rolls on the side wall of the cardboard;

[0076] S3. The glue scraping strips 15 on both sides scrape the overflowing glue on both sides of the cardboard. The glue is scraped up by the glue scraping strips 14 and squeezed into the glue scraping tank 11 during the continuous scraping process. Then it is squeezed to flow to the glue outlet 21.

[0077] S4. The coating roller 42 is squeezed and rotated, causing the coating sheet 43 to spread glue during rotation, thus applying the glue to the side wall of the cardboard. During rotation, the coating roller 42 and the coating sheet 43 are squeezed, and the resulting friction causes the coating rod 41 to squeeze the compression block 55 and the compression plate 54, compressing the compression component 53. This allows the coating roller 42 to move away from the glue outlet 21 during the rotational glue application process, allowing more glue to flow out and be easily scraped up by the coating sheet 43 to coat the side wall of the cardboard. The remaining structure is the same as in Example 2.

[0078] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
