Detailed Implementation

[0020] The present invention will now be further described with reference to the accompanying drawings.

[0021] The irregular edge sealing device of this utility model, such as Figures 1 to 3 As shown, it includes an edge banding tape traction wheel assembly 3, a glue application roller 6, and a tape application roller 7. The glue application roller 6 is located between the edge banding tape traction wheel assembly 3 and the tape application roller 7. A channel assembly 4 is provided between the edge banding tape traction wheel assembly 3 and the glue application roller 6, such as... Figure 2 and Figure 5As shown, the channel assembly 4 is formed with an edge sealing tape channel 403 for the edge sealing tape 99 to pass through, and the edge sealing tape channel 403 is provided with a channel air inlet 4011 corresponding to the glue-coated surface of the edge sealing tape 99, in other words, when the edge sealing tape 99 passes through the edge sealing tape channel 403, the side of the edge sealing tape 99 pre-coated with hot melt adhesive faces the channel air inlet 4011. Figures 1 to 4 As shown, the special-shaped edge sealing device further comprises a hot air assembly 41, the hot air assembly 41 comprises a hot air gun 410, a hot air supply pipe 411 and a temperature compensation hot air pipe 412, the hot air gun 410 is provided with an air outlet end 4101, the hot air gun 410 is a product of the prior art, for example, a hot air gun with a utility model patent publication number CN216347065U can be referred to, one end of the hot air supply pipe 411 is connected to the air outlet end 4101, the other end of the hot air supply pipe 411 is connected to the channel air inlet 4011, one end of the temperature compensation hot air pipe 412 is connected to the air outlet end 4101, and the other end of the temperature compensation hot air pipe 412 is formed with an air outlet 4121 for blowing air to the groove between the glue-coated surface of the edge sealing tape 99 and the plate 98.

[0022] The working principle of the special-shaped edge sealing device of the utility model will be briefly described as follows: Figure 1 and Figure 3 As shown, the special-shaped edge sealing device is further provided with an edge sealing tape unwinding assembly 2, the roll of the edge sealing tape 99 is placed in the circular box of the edge sealing tape unwinding assembly 2, and the special-shaped edge sealing device is further provided with a glue supply assembly 5, as shown by the dotted arrow in Figure 2 As shown, the edge sealing tape 99 passes between the two rollers of the edge sealing tape traction wheel set 3, and then the edge sealing tape passes through the edge sealing tape channel 403, and then the edge sealing tape 99 passes through the corresponding position of the glue roller 6, and then the edge sealing tape 99 passes around the tape sticking roller 7, the hot air gun 410 outputs hot air to the channel air inlet 4011, the hot air heats the hot melt adhesive on the edge sealing tape 99, so that the hot melt adhesive restores its viscosity, as shown in Figure 2 and Figure 3As shown, the side of the plate 98 is pressed against the tape roller 7 and the edge band pressing roller 8 by hand, so that the edge band 99 is adhered to the side of the plate 98. The side of the plate 98 is kept against the tape roller 7 and the edge band pressing roller 8 by hand, and the plate 98 is horizontally rotated at the same time, so that the edge band 99 wraps around the plate 98. During this process, the two rollers of the edge band traction wheel set 3 hold the edge band 99, and the edge band traction wheel set 3 and the tape roller 7 are driven to rotate by the motor, so that the edge band traction wheel set 3 can continuously convey the edge band 99 in the edge band unwinding assembly 2 to the tape roller 7. During this process, the edge band pressing roller 8 is pressed against the edge band 99 (the side without hot melt adhesive) adhered to the plate 98 by the elastic restoring force of the torsion spring, thereby facilitating the stable adhesion of the edge band 99 to the plate 98. During the above process, the glue supply assembly 5 does not work, and the edge band 99 does not contact the glue roller 6. During the adhesion process of the edge band 99 and the plate 98, the hot air gun 410 also inputs hot air to the temperature compensation hot air pipe 412, and the hot air is discharged from the air outlet 4121 to the side of the plate 98 and the side of the edge band 99 with hot melt adhesive, as shown in Figure 2 and Figure 3 As shown, the edge band 99 gradually approaches the side of the plate 98, so that the side of the plate 98 and the side of the edge band 99 with hot melt adhesive form the above-mentioned slot structure. By arranging the temperature compensation hot air pipe 412, the hot melt adhesive on the edge band 99 can be prevented from losing adhesion due to cooling before adhesion. When the edge band 99 without pre-coated adhesive is used, the hot air gun 410 does not work, as shown in Figure 2 The back roller 61 is swung to the side of the glue roller 6, and the back roller 61 pushes the edge band 99 to the side of the glue roller 6. The glue supply assembly 5 outputs glue to the other side of the glue roller 6 corresponding to the side of the glue roller 6. The glue roller 6 rotates to apply glue to one side of the edge band 99. After that, the edge band 99 with glue also passes through the tape roller 7, so that the edge band 99 can be adhered to the side of the plate 98. Since the structure for applying glue to the edge band 99 is prior art and is not the focus of the present application, it will not be described in detail here. It can also be understood that the present application adds the channel assembly 4 and the hot air assembly 41 to the existing path of the edge band 99. As shown in Figure 2 The cutting knife assembly 9 between the edge band traction wheel set 3 and the channel assembly 4 can cut the edge band 99. As described above, the special-shaped edge band device of the present application can use the edge band 99 with pre-coated hot melt adhesive, or the edge band 99 without pre-coated adhesive, so the application range is relatively large, which is conducive to flexible production.

[0023] Further, as shown in Figure 6As shown, the air outlet 4121 penetrates the temperature compensation hot air pipe 412 on one side in the radial direction. In other words, the air outlet 4121 is formed on the cylindrical surface of the temperature compensation hot air pipe 412, and the air outlet 4121 does not completely penetrate the temperature compensation hot air pipe 412 along the diameter of the temperature compensation hot air pipe 412, as shown in Figure 4 As shown, the temperature compensation hot air pipe 412 is fitted into the door cylinder 413, as shown in Figure 7 As shown, the door cylinder 413 is provided with a plurality of air door openings for communicating with the air outlet 4121, and the air door openings are distributed in the circumferential direction. The length of each air door opening in the up-down direction is different. Specifically, the number of air door openings can be three, and the three air door openings are respectively a first air door opening 4131, a second air door opening 4132, and a third air door opening 4133. The circumferential width of the first air door opening 4131, the second air door opening 4132, and the third air door opening 4133 is consistent, but the axial length (i.e., the length in the up-down direction) of the first air door opening 4131, the second air door opening 4132, and the third air door opening 4133 is gradually increased. Moreover, the lower end of the first air door opening 4131, the lower end of the second air door opening 4132, and the lower end of the third air door opening 4133 are arranged at the same height. The door cylinder 413 can rotate relative to the temperature compensation hot air pipe 412, as shown in Figure 4 As shown, since the edge band 99 is attached to the side surface of the plate 98, when the thickness of the plate 98 is small, the first air door opening 4131 is rotated to be aligned with the air outlet 4121. Thus, the door cylinder 413 partially covers the air outlet 4121, so that the hot air is concentrated and effectively blown to the position of the edge band 99 that is about to be bonded to the plate 98, thereby reducing the waste of hot air. When the thickness of the plate 98 is increased, the width (in the up-down direction) of the edge band 99 is also increased, so that the second air door opening 4132 can be rotated to be aligned with the air outlet 4121. The door cylinder 413 covers the air outlet 4121 to a smaller extent, so that the actual air outlet height range of the temperature compensation hot air pipe 412 is increased to adapt to the width of the edge band 99.

[0024] Further, as shown in Figure 7As shown, the lower end of the door cylinder 413 is formed with a plurality of notches 4134 corresponding to the air door openings, and the temperature compensation hot air pipe 412 is provided with positioning pegs. Specifically, the lower end of the temperature compensation hot air pipe 412 is formed with positioning peg mounting holes 4122 located below the air outlet 4121, and the positioning peg mounting holes 4122 are screwed with the positioning pegs (it should be noted that the positioning pegs are not shown in the drawings). The positioning pegs can be selected from hexagonal head cylindrical head screws. The positioning pegs are clamped with the corresponding notches 4134, that is, when the notches 4134 corresponding to the air door openings are clamped with the positioning pegs, the air door openings are circumferentially aligned with the air outlet 4121. When it is necessary to switch the air door openings, the door cylinder 413 is moved upward (axially) to move the notches 4134 away from the positioning pegs, and then the door cylinder 413 is rotated to align the notches 4134 corresponding to the required air door openings with the positioning pegs. Then, the door cylinder 413 is moved downward to make the required air door openings the current effective air door openings. The combination of the positioning pegs and the notches 4134 is simple in structure, making it easy to switch the air door openings.

[0025] Further, as shown in Figure 5 The channel assembly 4 includes a first side plate 401, a second side plate 402, a channel top plate 404, and a channel bottom plate 405. The channel top plate 404 is arranged above the channel bottom plate 405, and the channel top plate 404 and the channel bottom plate 405 are arranged between the first side plate 401 and the second side plate 402. The first side plate 401, the second side plate 402, the channel top plate 404, and the channel bottom plate 405 form an edge sealing channel 403. The upper end of the second side plate 402 is fixedly connected with a support plate 4021, and the lower end of the support plate 4021 can be integrally connected with the upper end of the second side plate 402. The channel top plate 404 is fixedly connected (welded) with a hanging plate 4041, as shown in Figure 4 The support plate 4021 is formed with a long hole extending in the up-down direction, and the hanging plate 4041 is connected with the support plate 4021. The channel assembly 4 is provided with a locking handle 42, and the locking handle 42 is provided with a screw rod portion. The screw rod portion passes through the long hole and is screwed with the hanging plate 4041. When the locking handle 42 is tightened, the support plate 4021 is clamped and fixed between the hanging plate 4041 and the handle portion of the locking handle 42. When the locking handle 42 is loosened, the hanging plate 4041 can be moved up and down, so that the channel top plate 404 can be correspondingly moved up and down to adjust the position. The height of the edge sealing channel 403 is adapted to the width of the edge sealing tape 99. The hot air input into the edge sealing channel 403 through the hot air supply pipe 411 first heats the edge sealing tape 99, and then the dispersed hot air is blocked by the first side plate 401, the second side plate 402, the channel top plate 404, and the channel bottom plate 405, so that the heat is not easily lost to the outside of the edge sealing channel 403, thereby facilitating the hot melt adhesive on the edge sealing tape 99 to quickly recover the tackiness.

[0026] Further, as shown inFigure 5 As shown, the channel air inlet 4011 is formed in the first side plate 401, and the channel air inlet 4011 is formed with a grid structure, which can be left during laser cutting of the first side plate 401, and the grid structure can block larger debris from blowing onto the edge sealing tape 99. Figure 4 As shown, specifically, one end of the hot air conveying pipe 411 and one end of the temperature compensation hot air pipe 412 are connected to the air outlet end 4101 of the hot air gun 410 through the three-way part 414, and the other end of the hot air conveying pipe 411 is connected to the channel air inlet 4011 through the elbow part.

[0027] Further, as shown in Figure 1 and Figure 3 As shown, the special-shaped edge sealing device further comprises a workbench 1, and the workbench 1 comprises a plate material supporting area 100 and a mounting area 200. The workbench 1 and the mounting area 200 are rectangular, the mounting area 200 is located at the left rear part of the workbench 1, and thus the part of the workbench 1 except the mounting area 200 is the plate material supporting area 100. The edge sealing tape traction wheel set 3 and the glue roller 6 are arranged in the mounting area 200, and the tape roller 7 is arranged at the right front corner position of the mounting area 200. The plate material supporting area 100 is provided with universal balls 101 for contacting the bottom surface of the plate material 98, and the universal balls 101 are arranged in a rectangular array. The universal ball 101 is prior art, for example, refer to the universal ball disclosed in the Chinese Utility Model Patent Publication No. CN219605811U, and thus when the plate material 98 slides on the plate material supporting area 100, the bottom surface of the plate material 98 actually rolls relative to the universal balls 101, thereby facilitating to reduce the resistance when the plate material 98 is moved by hand, and relatively, the plate material 98 can be more reliably attached to the tape roller 7 (through the edge sealing tape 99).
