Description

Technical Field

[0001] The invention relates to the technical field of glue scraping, and in particular to a multifunctional edge glue scraping device and a use method thereof. Background Art

[0002] The packaging cardboard needs to be bonded during the production process. During the bonding process, glue needs to be applied to both sides of the cardboard to improve the bonding degree of the cardboard. When glue is applied to both sides of the cardboard, the bonding force between the cardboards can be significantly enhanced, which can ensure that the cardboard will not easily fall apart or shift during use, thereby ensuring that the overall structure of the packaging is more solid and not easy to deform or break.

[0003] The patent with the announcement number CN115871276A discloses a corrugated paper box glue scraping device with uniform glue scraping. The glue gathered on the side of the triangular scraper can be evenly spread on the side of the triangular scraper according to the thickness of the glue gap, and the excess glue is covered through the suction holes on the triangular scraper to achieve glue suction operation in the middle and both ends to avoid glue accumulation.

[0004] However, the prior art still has the following defects: The above device can only absorb glue when scraping glue at the edge, so as to remove excess glue at the edge. When removing glue, the glue cannot be used in real time. Glue is needed to connect different parts of the cardboard during the production process. It is necessary to apply glue not only on the two sides of the cardboard but also on the side wall. If the side wall is not covered and applied, the side wall of the cardboard cannot be connected to other cardboards, affecting the connection strength and stability of the side edge and the whole of the cardboard. When removing the glue on the side, the overflowed glue cannot be recycled, which reduces the utilization efficiency of the glue.

[0005] Therefore, after the cardboard is made, it is necessary to use a scraper device to apply glue to areas such as edges and corners to increase its connection strength and stability. Summary of the invention

[0006] In view of the problem in the prior art that when scraping the glue at the edge, the glue cannot be directly applied to the side wall of the cardboard, resulting in low glue utilization efficiency, a multifunctional edge scraping device and a use method thereof are proposed.

[0007] The purpose is that when scraping the edge glue, the overflowed glue can be directly and evenly smeared on the side wall of the cardboard, which not only improves the stability of the cardboard during assembly and bonding, but also improves the utilization efficiency of the overflowed glue.

[0008] The technical solution of the present invention is a multifunctional edge scraping device, comprising a scraping component; The scraping component includes a scraping assembly, a glue outlet assembly arranged on one side of the scraping assembly, and a rolling assembly arranged on one side of the bottom of the scraping assembly; A glue coating component is arranged on one side of the glue scraping component, and the glue coating component comprises a glue coating component arranged on one side of the glue outlet component, and compression components symmetrically arranged on both sides of the glue coating component; The scraper assembly includes two symmetrically arranged scraper bins, the two scraper bins are connected, push grooves are symmetrically arranged on the side walls of the two scraper bins, a raised block is arranged between the two scraper bins, scraper edges are symmetrically opened at the bottom edge positions of the two scraper bins, scraper strips are symmetrically arranged on both sides of the raised block, and exhaust holes are opened in the middle of one side of the two scraper bins, and the scraper strips are in contact with the edge of the scraper edge; The glue scraping component is used to scrape the overflowed glue at the edges of both sides of the cardboard, and the glue coating component is used to apply the glue scraped by the glue scraping component to the side edges of the cardboard. The whole formed by the glue scraping component and the glue coating component is arched.

[0009] By adopting the above technical scheme, a scraping component is provided to scrape the glue overflowing from the side wall of the cardboard, and the scraped glue is smeared on the side edge of the cardboard through the glue coating component. The glue overflowing from the side of the cardboard can be scraped clean and the scraped glue can be smeared on the side edge of the cardboard again, thereby improving the utilization rate of the overflowed glue and avoiding the waste of the overflowed glue from the side of the cardboard. When scraping glue, the glue is scraped by the scraping strip. The setting of the rubber material of the scraping strip avoids squeezing the side of the cardboard during the scraping process, causing deformation of the side of the cardboard. When scraping, the scraping strip scrapes along the side edge of the cardboard. During the scraping process, the scraping strip will bend along the scraping direction. When the overflowing glue is thicker, the scraping strip can first push and flatten the overflowing glue, so that the glue can gradually enter the scraping glue bin, so that all the glue does not enter and cause accumulation and blockage of glue at the scraping glue bin mouth, so that the glue can quickly enter the scraping glue bin, and the scraped glue enters from the scraping glue bins on both sides under the action of the ridges, so as to avoid the glue entering from both sides being squeezed into the middle of the two scraping glue bins, causing the glue to stay and accumulate, and the glue in the middle cannot smoothly enter the glue-coated parts, and the glue on both sides is diverted, thereby improving the utilization rate of the glue. And because the glue is continuously squeezed into the glue scraping bin during the glue scraping process, overflowed glue of different thicknesses is collected in the glue scraping bin. When glue with a thicker thickness is scraped in, a relatively closed state is formed in the glue scraping bin, so that there is space between the glue squeezed in. The setting of the exhaust holes can discharge the air between the glues of different thicknesses when they are squeezed into the glue scraping bin, so that uniform glue can be squeezed out of the glue coating component, so that the amount of glue coating on the side of the cardboard is consistent, thereby improving the quality of glue coating on the side of the cardboard.

[0010] Furthermore, the two scraper bins are in an outwardly expanding shape, and the projection of the edge of the middle connection at the top of the two scraper bins in the horizontal direction is longer than the projection of the edge of the raised block in the horizontal direction.

[0011] By adopting the above technical solution, the glue scraper bin expands outward so that the glue can enter along the inside of the glue scraper bin, making it easier for the glue to enter the glue scraper bin after being scraped up, and the horizontal projection of the edge of the middle connection at the top of the two glue scraper bins 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 glue scraper bin after entering the glue scraper bin.

[0012] Furthermore, the angle formed by the scraping strip and the scraping edge with one side of the cardboard is 45 degrees, and the scraping strip is made of rubber, and the scraping strip and the scraping edge are both inclined.

[0013] By adopting the above technical solution, the glue on the edge of the cardboard can be uniformly scraped at 45 degrees, which is convenient for the later edge bonding of the cardboard and can prevent the glue on the edge from being scraped away too much, thereby reducing the adhesion between the later cardboards. The setting of the inclined scraping strip and the scraping edge can avoid damage to the edge of the cardboard when scraping the glue, and can also achieve the effect of rapid scraping.

[0014] Furthermore, the glue outlet assembly includes a glue outlet arranged on one side of the two glue scraping bins, and the glue outlet is flat and arranged near the side of the paperboard.

[0015] By adopting the above technical solution, the flat glue outlet allows the glue entering the glue scraping bin to form strips, which is convenient for the glue coating component to coat the glue, so that the glue can be evenly coated on the side wall of the cardboard.

[0016] Furthermore, the rolling assembly includes mounting blocks symmetrically arranged at the bottom of the two scraper bins, a connecting rod arranged in the middle of the two mounting blocks, and a rotating roller arranged in the middle of the connecting rod.

[0017] By adopting the above technical solution, the rotating setting allows the glue coating device to move along the side wall of the cardboard when pushed, reducing the resistance during the movement of the device and making the device arched. The glue entering the glue scraping bin can flow toward the glue outlet, improving the fluidity of the glue.

[0018] Furthermore, the glue coating assembly includes a glue coating rod arranged at the middle position of the two compression assemblies, a glue coating roller arranged in the middle of the glue coating rod, and a glue coating sheet arranged on the glue coating roller in a circular inclined array, and the glue coating sheet is made of rubber.

[0019] By adopting the above technical solution, when applying glue, the glue coating roller and the glue coating sheet are squeezed and driven to rotate, so that the glue coating sheet can scrape the glue at the glue outlet and smear the glue on the side wall of the cardboard, completing the function of smearing the glue overflowing from the side of the cardboard to the side wall of the cardboard.

[0020] Furthermore, the glue coating rod is arranged on one side of the center of the glue coating roller, and the glue coating sheet includes a long sheet and a short sheet, and the circle formed at the edge of the glue coating sheet is concentric with the glue coating rod.

[0021] By adopting the above technical solution, the glue coating rod is not arranged at the center position of the glue coating roller, so that when the glue coating roller rotates, the long piece and the short piece spread different amounts of glue from the glue outlet, that is, the glue coating roller intermittently applies glue of different thicknesses during the rotation process. Since the amount of glue overflowing from the surface of the cardboard during gluing is small, a small amount of glue can be applied more evenly on the side wall of the cardboard, avoiding the situation that after the glue is scraped off the side of the cardboard, half of the side wall of the cardboard is coated with glue, and the other half is not coated with glue.

[0022] Furthermore, the glue coating sheet and the glue coating roller are integrally arranged in the lower middle part of the glue outlet, and the connecting line of any two opposite sides of the glue coating strips in the cross-sectional direction thereof is longer than the height of the glue outlet.

[0023] By adopting the above technical solution, the setting can ensure that after the coating is completed, under the resetting action of the compression component, the glue coating sheet and the glue coating roller are reset to block the glue outlet, preventing dust and impurities from entering the outlet and causing blockage during subsequent use, thereby increasing the service life of the device.

[0024] Furthermore, the compression assembly includes a compression groove opened in one side of the glue outlet assembly, a compression hole arranged on one side of the compression groove, a compression member arranged in the compression groove, a compression plate arranged on one side of the compression member, and a compression block arranged on one side of the compression plate, and one end of the glue coating rod passes through the compression hole and is rotatably connected to the middle part of the compression block.

[0025] By adopting the above technical scheme, when the glue coating roller moves on the side wall of the cardboard, the glue coating roller and the glue coating sheet are squeezed, and the friction force generated during the movement causes the glue coating rod to squeeze the compression block and the compression plate, so that the compression part is compressed. Firstly, the glue coating roller can be away from the glue outlet during the rotation and gluing process, so that more glue flows out and is convenient for the glue coating sheet to scrape and smear the side wall of the cardboard. Secondly, when the gluing stops, the glue coating roller resets and drives the glue coating sheet to seal the glue outlet to prevent impurities from entering the scraping bin.

[0026] Another object of the present invention is to provide a method for using a multifunctional edge glue scraping device, the purpose of which is to improve the utilization efficiency of edge glue after scraping and enhance the strength and stability of cardboard after bonding.

[0027] To achieve the above object, the present invention provides the following technical solution: a method for using a multifunctional edge scraping device, comprising the following steps: When scraping glue, hold the scraper device with your hand, stick the scraper device to the side of the paperboard, press the push groove to push the scraper device as a whole to move on the side wall of the paperboard; The rotating roller is attached to the side wall of the paperboard and rolls on the side wall of the paperboard; The scraping strips on both sides scrape the overflowed glue on the sides of the cardboard. The glue is scraped up by the scraping edge and squeezed into the scraping bin during the continuous scraping process, and then squeezed and flows to the glue outlet; The glue coating roller is squeezed and rotated, so that the glue coating sheet smears the glue during the rotation, so that the glue is smeared on the side wall of the cardboard.

[0028] Compared with the prior art, the present invention has the following beneficial effects: 1. The glue scraping component is provided to scrape the glue overflowing from the side wall of the cardboard, and the scraped glue is smeared on the side of the cardboard through the gluing component. The glue overflowing from the side of the cardboard can be scraped clean and the scraped glue can be smeared on the side of the cardboard again, thereby improving the utilization rate of the overflowed glue and avoiding the waste of the overflowed glue from the side of the cardboard.

[0029] 2. The scraper strip is provided to push and flatten the overflowed glue first, so that the glue can gradually enter the scraper bin, so that all the glue does not enter and cause the accumulation and blockage of glue at the scraper bin mouth. The glue can quickly enter the scraper bin, and the scraped glue enters from the scraper bins on both sides respectively under the action of the raised block, avoiding the retention and accumulation of glue, and diverting the glue on both sides, thereby improving the utilization rate of the glue.

[0030] 3. The compression component can be set up so that the glue coating roller can be kept away from the glue outlet during the rotating gluing process, so that more glue can flow out to facilitate the glue coating sheet to scrape it and smear it on the side wall of the cardboard. When the gluing stops, the glue coating roller resets and drives the glue coating sheet to seal the glue outlet to prevent impurities from entering the glue scraping bin and increase the service life of the device.

[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0034] Example 1, reference Figure 1-Figure 5 , which is the first embodiment of the present invention, provides a multifunctional edge scraping device, including a scraping component; the scraping component includes a scraping component 1, a glue outlet component 2 installed on one side of the scraping component 1, and a rolling component 3 installed on one side of the bottom of the scraping component 1; a glue coating component is installed on one side of the scraping component, and the glue coating component includes a glue coating component 4 installed on one side of the glue outlet component 2, and a compression component 5 symmetrically installed on both sides of the glue coating component 4; the scraping component 1 includes two symmetrically installed scraping bins 11, the two scraping bins 11 are connected to each other, and are symmetrically opened on the sides of the two scraping bins 11 A pushing groove 12 on the wall, a raised block 13 fixedly connected between the two scraping glue bins 11, scraping glue edges 14 symmetrically arranged at the bottom edge positions of the two scraping glue bins 11, scraping glue strips 15 symmetrically fixedly connected at both sides of the raised block 13, and exhaust holes 16 arranged in the middle of one side of the two scraping glue bins 11, and the scraping glue strips 15 are in contact with the edge of the scraping glue edge 14; the scraping glue component is used to scrape the overflowed glue at the edges of both sides of the cardboard, and the glue coating component is used to apply the glue scraped out by the scraping glue component to the side edges of the cardboard, and the whole composed of the scraping glue component and the glue coating component is arched.

[0035] Specifically, a glue scraping component is provided to scrape the glue overflowing from the side wall of the cardboard, and the scraped glue is smeared on the side edge of the cardboard through the glue coating component, so that the glue overflowing from the side of the cardboard can be scraped clean, and the scraped glue can be smeared on the side edge of the cardboard again, thereby improving the utilization rate of the overflowed glue and avoiding the waste of the overflowed glue from the side of the cardboard. When scraping glue, the glue is scraped by the scraping strip 15. The rubber material of the scraping strip 15 is set to avoid squeezing the side of the cardboard during the scraping process, causing deformation of the side of the cardboard. When scraping, the scraping strip 15 scrapes along the side edge of the cardboard. During the scraping process, the scraping strip 15 will bend along the scraping direction. When the overflowing glue is thicker, the scraping strip 15 can first push the overflowing glue to flatten it, so that the glue can gradually enter the scraping glue bin 11, so as not to cause all the glue to enter and cause the accumulation and blockage of glue in the glue outlet 21, so that the glue can quickly enter the scraping glue bin 11, and the scraped glue enters from the scraping glue bins 11 on both sides under the action of the ridge block 13, so as to avoid the glue entering from both sides from being squeezed into the middle of the two scraping glue bins 11, causing the glue to stay and accumulate, so that the glue in the middle cannot smoothly enter the glue coating component, and the glue on both sides is diverted, thereby improving the utilization rate of the glue. Furthermore, since the glue is continuously squeezed into the glue scraping bin 11 during the glue scraping process, the overflowed glue of different thicknesses is collected in the glue scraping bin 11. When the thicker glue is scraped in, a relatively closed state is formed in the glue scraping bin 11, so that there is space between the squeezed glue. The setting of the vent holes 16 allows the air between the glues of different thicknesses to be discharged when being squeezed into the glue scraping bin 11, so that uniform glue can be squeezed out of the glue coating component, so that the amount of glue coating on the side of the cardboard is consistent, thereby improving the quality of the glue coating on the side of the cardboard.

[0036] Reference Figure 1 , Figure 4 and Figure 5 The two scraper bins 11 are expanded outward, and the projection of the edge of the middle connection at the top of the two scraper bins 11 in the horizontal direction is longer than the projection of the edge of the raised block 13 in the horizontal direction.

[0037] Specifically, the glue scraper bin 11 is expanded outward so that the glue can enter along the inside of the glue scraper bin 11, making it easier for the glue to enter the glue scraper bin 11 after being scraped up, and the horizontal projection of the edge of the middle connection at the top of the two glue scraper bins 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 glue scraper bin 11 after entering the glue scraper bin 11.

[0038] Reference Figure 1-Figure 5The angle formed by the scraping strip 15 and the scraping edge 14 with one side of the paperboard is 45 degrees, and the scraping strip 15 is made of rubber, and the scraping strip 15 and the scraping edge 14 are both inclined.

[0039] Specifically, the glue on the edge of the cardboard can be uniformly scraped at 45 degrees, which is convenient for the later edge bonding of the cardboard and can prevent the glue on the edge from being scraped away too much, thereby reducing the adhesion between the later cardboards. The inclined scraping strip 15 and the scraping edge 14 can avoid damage to the edge of the cardboard when scraping the glue, and can also achieve the effect of rapid scraping.

[0040] Reference Figure 1-Figure 7 The glue outlet assembly 2 includes a glue outlet 21 opened on one side of the two glue scraping bins 11, and the glue outlet 21 is flat and opened on a side close to the cardboard.

[0041] Specifically, the flat glue outlet 21 allows the glue entering the glue scraping bin 11 to form strips, which facilitates the glue coating component 4 to coat the glue, so that the glue can be evenly coated on the side wall of the cardboard.

[0042] Reference Figure 1-Figure 8 The rolling assembly 3 includes a mounting block 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 .

[0043] Specifically, the setting of the rotating roller 33 allows the glue coating device to move along the side wall of the cardboard when pushed, reducing the resistance during the movement of the device and making the device arched. The glue entering the glue scraping chamber 11 can flow toward the glue outlet 21, improving the fluidity of the glue.

[0044] Example 2, reference Figure 1-Figure 10 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that the glue coating component 4 includes a glue coating rod 41 rotatably connected to the middle position of the two compression components 5, a glue coating roller 42 fixedly connected to the middle of the glue coating rod 41, and a glue coating sheet 43 fixedly connected to the glue coating roller 42 in a ring-shaped inclined array, and the glue coating sheet 43 is made of rubber.

[0045] Specifically, when applying glue, the glue coating roller 42 and the glue coating sheet 43 are squeezed and driven to rotate, so that the glue coating sheet 43 can scrape the glue at the glue outlet 21 and spread the glue on the side wall of the cardboard, completing the function of smearing the glue overflowing from the side of the cardboard onto the side wall of the cardboard.

[0046] Reference Fig.10 The glue coating rod 41 is fixedly connected to one side of the center of the glue coating roller 42, and the glue coating sheet 43 includes a long sheet 431 and a short sheet 432. The circle formed at the edge of the glue coating sheet 43 is concentric with the glue coating rod 41.

[0047] Specifically, the glue coating rod 41 is not arranged at the center position of the glue coating roller 42, so that when the glue coating roller 42 rotates, the long piece 431 and the short piece 432 spread different amounts of glue from the glue outlet 21, that is, the glue coating roller 42 intermittently applies glue of different thicknesses during the rotation process. Since the amount of glue overflowing from the surface of the cardboard during glue coating is small, a small amount of glue can be applied more evenly on 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 with glue after the glue is scraped off the side edge of the cardboard.

[0048] Reference Figure 1-Figure 10 The glue coating sheet 43 and the glue coating roller 42 are integrally installed in the middle and lower part of the glue outlet 21, and the connecting line of any two opposite sides of the glue coating strips in the cross-sectional direction is longer than the height of the glue outlet 21.

[0049] Specifically, such an arrangement allows the glue coating sheet 43 and the glue coating roller 42 to reset after coating, under the resetting action of the compression assembly 5, to block the glue outlet 21, thereby preventing dust and impurities from entering the outlet and causing blockage during subsequent use, thereby increasing the service life of the device.

[0050] Reference Figure 1-Figure 11 The compression assembly 5 includes a compression groove 51 opened in one side of the glue discharge 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 to one side of the compression member 53, and a compression block 55 fixedly connected to one side of the compression plate 54, and one end of the glue coating rod 41 passes through the compression hole 52 and is rotatably connected to the middle part of the compression block 55.

[0051] Specifically, when the glue roller 42 moves on the side wall of the paperboard, the glue roller 42 and the glue sheet 43 are squeezed, and the friction generated during the movement causes the glue rod 41 to squeeze the compression block 55 and the compression plate 54, so that the compression member 53 is compressed. First, the glue roller 42 can be away from the glue outlet 21 during the rotation and gluing process, so that more glue flows out and is easy to be scraped by the glue sheet 43 to smear the side wall of the paperboard. Second, when the glue is stopped, the glue roller 42 is reset to drive the glue sheet 43 to block the glue outlet 21 to prevent impurities from entering the scraping bin 11. The rest of the structure is the same as that of Example 1.

[0052] Example 3, reference Figure 1-Figure 11 , which is the third embodiment of the present invention, and this embodiment is different from the second embodiment in that: S1. When scraping glue, hold the scraper with your hand, attach the scraper to the side of the paperboard, and press the push groove 12 to push the scraper as a whole to move on the side wall of the paperboard; S2, the rotating roller 33 is attached to the side wall of the cardboard and rolls on the side wall of the cardboard; S3, the scraping strips 15 on both sides scrape the overflowed glue on the sides of the cardboard, the glue is scraped up by the scraping edge 14, and is squeezed into the scraping bin 11 during the continuous scraping process, and then squeezed to flow to the glue outlet 21; S4, the glue roller 42 is squeezed and rotated, so that the glue sheet 43 smears the glue during the rotation process, so that the glue is applied to the side wall of the cardboard. During the rotation process, the glue roller 42 and the glue sheet 43 are squeezed, and the friction generated during the movement process causes the glue rod 41 to squeeze the compression block 55 and the compression plate 54, so that the compression member 53 is compressed, so that the glue roller 42 can be away from the glue outlet 21 during the rotation and gluing process, so that more glue flows out to facilitate the glue sheet 43 to scrape it and apply it to the side wall of the cardboard. The rest of the structure is the same as that of Example 2.

[0053] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
