Description

Technical Field

[0001] This invention relates to the technical field of cabinet manufacturing equipment, specifically to a splicing panel sidewall adhesive device. Background Technology

[0002] Whole-house customization is a home customization solution that integrates home design, customization, installation and other services. It is a home furnishing solution that is made by home furnishing companies based on the design requirements of consumers, on the basis of large-scale production.

[0003] With technological advancements, whole-house customization has expanded from its initial focus on wardrobes and cabinets to include various types of wooden furniture. Its advantage lies in ensuring a unified style across all wooden pieces. Currently, many whole-house customization companies use particleboard, which is made by breaking wood into chips, mixing them with adhesive, and then hot-pressing them into a board. Particleboard has a relatively high adhesive content, requiring edge banding to prevent harmful substances from the adhesive from being released into the air.

[0004] Both actual production and consumer feedback indicate that solid wood spliced ​​panels are a superior choice for cabinet panels. Although adjacent panels in solid wood spliced ​​panels are also glued together, the amount of glue used is far less than that of particleboard, making it relatively more environmentally friendly. However, because the amount of glue used to bond the panels cannot be guaranteed to be consistent during the glue application process, the glue layer thickness between adjacent panels varies, making it difficult to control the width accuracy of the spliced ​​panels. If the glue layer thickness between adjacent panels is too thick, it will directly affect the overall strength performance of the panel. Therefore, a glue application device for spliced ​​panels is needed, one that can control the glue layer thickness after the adjacent panels are glued together. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a sidewall adhesive device for splicing panels. This device can apply adhesive to the sidewalls of splicing panels while ensuring a consistent adhesive thickness, thus guaranteeing the quality of adhesive application and the bonding quality between the panels. It also prevents excessive adhesive from overflowing onto the panel surface during splicing and fixing, avoiding waste and contamination. The adhesive, initially subject to centrifugal force, tends to move towards the annular boss during rotation. However, the bending structures of vertical ribs A and B, as well as the bending structures of the horizontal and connecting rods, effectively block this movement, reducing or even eliminating the impact of the adhesive's movement towards the annular boss. The adhesive surface is scraped by the horizontal scraper, and the centrifugal force of the rotating adhesive prevents the adhesive from moving towards the annular boss, thus ensuring a uniform thickness distribution of the adhesive in the annular adhesive groove after the scraping action of the horizontal scraper. The concave structure of the horizontal scraper creates an adhesive storage area during the scraping process, further preventing the adhesive from moving towards the annular boss due to centrifugal force. Simultaneously, the lower edge of the horizontal scraper extends towards the direction of rotation, facilitating the scooping of excess adhesive into the storage area and ensuring that the adhesive level after scraping meets the bonding requirements of the spliced ​​panels. The combined effect of the annular boss and the central boss minimizes the amount of adhesive moving towards the annular boss during scraping. The adhesive overflows from the annular glue groove. The annular overflow groove creates a buffer zone between the annular glue groove and shaft hole B. When the adhesive is squeezed towards the central boss by the edge of the horizontal scraper blade near the central boss during rotation, and accidentally overflows from the top surface of the central boss, the adhesive can temporarily overflow into the annular overflow groove, preventing the adhesive from entering shaft hole B and contaminating shaft hole B, the vertical shaft, and the base. The adjusting bolts allow for adjustment of the disc height according to different splicing plate models, thereby adjusting the distance between the bottom edge of the horizontal scraper blade (i.e., the adhesive surface after scraping) and the top edges of vertical ribs A and B, improving the applicability of this application. The horizontal scraper blade... The limiting plate facilitates the positioning and installation of the horizontal scraper plate; the upper part of the scraper plate is fixed to the horizontal bar, making it easy to position the scraper plate with the horizontal bar. Furthermore, the upper part of the scraper plate forms a fulcrum through the horizontal bar, increasing the elastic strength of the bottom edge of the scraper plate. This prevents the scraper plate from breaking if it scrapes against ribs A and B; instead, the scraper plate undergoes elastic deformation until it separates from ribs A and B. The fixing through-holes in the connecting rod and the vertical shaft not only fix the connecting rod to the vertical shaft but also allow adjustment of the position of the horizontal scraper plate relative to the annular glue groove by the extent to which the connecting rod extends into the vertical shaft.

[0006] The technical solution adopted in this invention is: A splicing panel sidewall adhesive device includes a base, on which a disc is fixedly connected. An annular boss and a central boss are coaxially arranged on the top edge and center of the disc, respectively. An annular adhesive groove is formed on the top surface of the disc between the annular boss and the central boss. Multiple vertical ribs A are evenly distributed at the bottom of the annular adhesive groove. The top edges of each vertical rib A are located on the same horizontal plane and are 1-2 mm higher than the bottom of the annular adhesive groove. A horizontal scraper plate, rotating around the disc axis via a driving device, is also provided inside the annular adhesive groove. The two ends of the horizontal scraper plate extend to the inner sidewall of the annular boss and the sidewall of the central boss, respectively. A gap is provided between the bottom edge of the horizontal scraper plate and the top edge of the vertical rib A.

[0007] A further improvement of the present invention is that the horizontal scraper is fixedly connected to one side of the horizontal rod, and the end of the horizontal rod facing the center of the disc is fixedly connected to a vertical shaft rotatably connected to the center of the disc. The vertical shaft is connected to the driving device for transmission, and the horizontal rod rotates around the vertical shaft to the side of the horizontal scraper.

[0008] A further improvement of the present invention is that the horizontal scraper includes a scraper plate, the upper part of which is fixed to one side of the horizontal bar, and the lower part of which is located below the horizontal bar and recessed towards the side where the horizontal bar is located.

[0009] A further improvement of the present invention is that the horizontal scraper plate further includes a limiting plate fixed to the top of the scraper plate, and the limiting plate is in close contact with the top of the horizontal rod.

[0010] A further improvement of the present invention is that the upper part of the adhesive scraper plate is attached to the horizontal bar.

[0011] A further improvement of the present invention is that the glue scraping plate is fixedly connected to the horizontal bar by fixing bolts A, and there are multiple fixing bolts A, which are evenly distributed along the axial direction of the horizontal bar.

[0012] A further improvement of the present invention is that a connecting rod is fixedly connected to the end of the horizontal rod facing the vertical shaft, the connecting rod passes through a fixing through hole provided on the top of the side wall of the vertical shaft, and the top of the vertical shaft is fixed to the connecting rod passing through the fixing through hole by a tightening bolt.

[0013] A further improvement of the present invention is that the horizontal rod is bent relative to the connecting rod toward the side where the glue scraping plate is located, the middle part of the vertical rib A is bent, the end of the vertical rib A facing the annular boss is bent toward the side facing the rotation direction of the glue scraping plate, and the end of the vertical rib A facing the central boss points toward the axis of the disk.

[0014] A further improvement of the present invention is that a vertical rib B is provided between two adjacent vertical ribs A, the phase angle between vertical rib B and its adjacent vertical rib A is equal, the top edge of vertical rib B is flush with the top edge of vertical rib A, vertical rib B is bent in the middle, the bending direction and angle of vertical rib B are the same as those of vertical rib A, the bending point of vertical rib B and the bending point of vertical rib A are located on the same circle A with the center of the disk axis as the center; the end of vertical rib B facing the central boss points to the center of the disk axis, and the distance between the end of vertical rib B facing the central boss and the center of the disk axis is greater than the distance between the end of vertical rib A facing the central boss and the center of the disk axis; the end of vertical rib B facing the annular boss and the end of vertical rib A facing the annular boss are located on the same circle B with the center of the disk axis as the center.

[0015] A further improvement of the present invention is that the driving device is fixedly connected to the bottom of the base, and the vertical shaft connected to the driving device passes through the shaft hole A provided in the base and the shaft hole B provided in the disc in sequence. The vertical shaft is rotatably connected to the shaft hole A and the shaft hole B through bearings.

[0016] A further improvement of the present invention is that the base is connected to the disk by a plurality of adjusting bolts, the adjusting bolts being evenly distributed around the axis of the disk, the adjusting bolts being threadedly connected to the threaded holes provided on the base, and the top of the adjusting bolts passing upward through the threaded holes and connecting to the positioning holes provided on the bottom surface of the disk.

[0017] A further improvement of the present invention is that the top surface of the central boss is also provided with an annular overflow groove coaxially.

[0018] A further improvement of the present invention is that the height of the top surface of the annular boss is greater than or equal to the height of the top surface of the central boss.

[0019] The beneficial effects of this invention are as follows: First, the splicing panel sidewall adhesive device of the present invention can apply adhesive to the sidewall of the splicing panel and ensure that the thickness of the adhesive is always consistent, thereby ensuring the adhesive quality of the splicing panel sidewall, and thus ensuring the bonding quality between the splicing panels. At the same time, it also avoids excessive adhesive from overflowing onto the surface of the splicing panel during splicing and fixing, which would lead to adhesive waste and contamination of the panel.

[0020] Secondly, in the splicing plate sidewall adhesive device of the present invention, the adhesive liquid, which is originally subjected to centrifugal force, will move towards the annular boss during rotation. However, the bending structure of the vertical ribs A and B, as well as the bending structure of the horizontal rod and the connecting rod, will block the adhesive liquid from moving towards the annular boss. This reduces or even cancels the centrifugal force of the adhesive liquid surface being scraped by the horizontal scraper and rotating with it. As a result, the adhesive liquid will not move towards the annular boss as much as possible, thereby ensuring that the adhesive liquid in the annular adhesive groove has a uniform thickness distribution after the scraping action of the horizontal scraper.

[0021] Third, the adhesive device for the side wall of the splicing plate of the present invention, through the concave structure of the horizontal scraper, forms an adhesive storage area during the scraping process, thereby further preventing the adhesive from moving towards the annular boss due to centrifugal force. At the same time, the lower edge of the horizontal scraper extends towards the rotation direction, making it easy to scoop up excess adhesive into the adhesive storage area and ensuring that the height of the adhesive level after scraping meets the adhesive requirements of the splicing plate.

[0022] Fourth, the adhesive device for the side wall of the splicing plate of the present invention, through the action of the annular boss and the central boss, minimizes the leakage of adhesive from the annular groove when scraping adhesive.

[0023] Fifth, the splicing plate sidewall adhesive device of the present invention, by setting an annular overflow groove, forms a buffer zone between the annular glue groove and the shaft hole B. When the glue is squeezed towards the central boss by the edge of the horizontal glue scraper near the central boss under the rotation of the horizontal glue scraper, and accidentally overflows from the top surface of the central boss, the glue can temporarily overflow into the annular overflow groove, avoiding the glue from entering the shaft hole B and contaminating the shaft hole B, the vertical shaft and the base.

[0024] Sixth, the splicing plate sidewall adhesive device of the present invention, through the action of adjusting bolts, can adjust the height of the disc according to different models of splicing plates, thereby adjusting the distance between the bottom edge of the horizontal scraper, i.e. the glue liquid surface after scraping, and the top edge of the vertical ribs A and B, thus improving the applicability of this application.

[0025] Seventh, the splicing panel sidewall adhesive device of the present invention facilitates the positioning and installation of the horizontal adhesive scraper by using a limiting plate provided by the horizontal adhesive scraper.

[0026] Eighth, the adhesive device for the side wall of the splicing plate of the present invention fixes the upper part of the adhesive scraping plate to the horizontal bar, thereby making it easy to position the adhesive scraping plate with the horizontal bar. Moreover, the upper part of the adhesive scraping plate forms a fulcrum through the horizontal bar, thereby increasing the elastic strength of the bottom edge of the adhesive scraping plate. This prevents the adhesive scraping plate from breaking the vertical rib A or vertical rib B if the bottom edge of the adhesive scraping plate scrapes the vertical rib A or vertical rib B. Instead, the adhesive scraping plate undergoes elastic deformation until it separates from the vertical rib A or vertical rib B.

[0027] Ninth, the splicing plate sidewall adhesive device of the present invention, through the fixed through hole provided in the connecting rod and the vertical shaft, can not only fix the connecting rod and the vertical shaft, but also adjust the position of the horizontal scraper relative to the annular adhesive groove by the extent to which the connecting rod extends into the vertical shaft.

[0034] The horizontal scraper plate 7 also includes a limiting plate 24 fixed to the top of the scraper plate 23, and the limiting plate 24 is in close contact with the top of the horizontal bar 10.

[0035] The upper part of the adhesive scraper plate 23 is attached to the horizontal bar 10.

[0036] The adhesive scraping plate 23 is fixedly connected to the horizontal bar 10 by fixing bolts A22. There are multiple fixing bolts A22, which are evenly distributed along the axial direction of the horizontal bar 10.

[0037] A connecting rod 11 is fixedly connected to one end of the horizontal rod 10 facing the vertical shaft 9. The connecting rod 11 passes through a fixing through hole 13 provided on the top of the side wall of the vertical shaft 9. The top end of the vertical shaft 9 is fixed to the connecting rod 11 passing through the fixing through hole 13 by a tightening bolt 12.

[0038] The horizontal bar 10 bends relative to the connecting bar 11 toward the side where the glue scraping plate 23 is located. The middle part of the vertical rib A6 bends. The end of the vertical rib A6 facing the annular boss 3 bends toward the side facing the rotation direction of the glue scraping plate 23. The end of the vertical rib A6 facing the central boss 4 points toward the axis of the disk 2.

[0039] A vertical rib B21 is also provided between two adjacent vertical ribs A6. The phase angle between vertical rib B21 and its adjacent vertical rib A6 is equal. The top edge of vertical rib B21 is flush with the top edge of vertical rib A6. Vertical rib B21 is bent in the middle. The bending direction and angle of vertical rib B21 are the same as those of vertical rib A6. The bending point of vertical rib B21 and the bending point of vertical rib A6 are located on the same circle A centered on the axis of disk 2. The end of vertical rib B21 facing the central boss 4 points to the axis of disk 2, and the distance between the end of vertical rib B21 facing the central boss 4 and the axis of disk 2 is greater than the distance between the end of vertical rib A6 facing the central boss 4 and the axis of disk 2. The end of vertical rib B21 facing the annular boss 3 and the end of vertical rib A6 facing the annular boss 3 are located on the same circle B centered on the axis of disk 2.

[0040] The drive device 8 is fixedly connected to the bottom of the base 1. The vertical shaft 9, which is connected to the drive device 8, passes through the shaft hole A14 provided in the base 1 and the shaft hole B15 provided in the disc 2 in sequence. The vertical shaft 9 is rotatably connected to the shaft hole A14 and the shaft hole B15 through the bearing 19.

[0041] The base 1 is connected to the disc 2 by a plurality of adjusting bolts 16. The adjusting bolts 16 are evenly distributed around the axis of the disc 2. The adjusting bolts 16 are threadedly connected to the threaded holes 17 provided on the base 1, and the top of the adjusting bolts 16 passes through the threaded holes 17 and connects to the positioning holes 18 provided on the bottom surface of the disc 2.

[0042] The top surface of the central boss 4 is also coaxially provided with an annular overflow groove 20.

[0043] The height of the top surface of the annular boss 3 is greater than or equal to the height of the top surface of the central boss 4.

[0044] In this application, the adjusting bolt 16 is adjusted beforehand so that the height difference between the top edge of the vertical rib A6 and the top edge of the vertical rib B21 and the bottom edge of the horizontal scraper 7 is equal to the required adhesive thickness; then, adhesive is added into the annular adhesive groove 5 so that the liquid level of the adhesive is higher than the horizontal scraper 7 and lower than the top surface of the annular boss 3 and the top surface of the central boss 4; then, the drive device 8 is started to drive the horizontal scraper 7 to rotate around the axis. Whenever the horizontal scraper 7 just passes a certain position in the annular adhesive groove 5, the corresponding position... The level of the adhesive is flush with the bottom edge of the horizontal scraper 7. Then, one side wall of the splicing plate to be glued is placed on the vertical ribs A6 and B21 at that position. At this time, the adhesive comes into contact with the end face of the side wall of the splicing plate, so that the end face of the side wall of the splicing plate can be coated with an adhesive layer of the corresponding thickness. Then, the splicing plate with adhesive is removed from the annular glue tank 5 and fixedly connected to the corresponding part of other splicing plates. When the level of the adhesive in the annular glue tank 5 is close to the bottom edge of the horizontal scraper 7, more adhesive is added to the annular glue tank 5.
