[0056] Reference Figure 1As shown, the automatic edge banding machine according to the first embodiment of the present invention includes a plate conveyor 100, a glue pot mechanism 200, a belt feeding structure 300 and a color supply mechanism 400. The plate conveyor 100 is used to convey the plate (conveying the plate and moving it back and forth); the glue pot mechanism 200 is located on one side of the plate conveyor 100 (located on the left side of the plate conveyor 100), and the glue pot mechanism 200 can apply glue to the side edge of the plate; the belt feeding structure 300 is located on one side of the plate conveyor 100 (located on the left side of the plate conveyor 100) and in front of the glue pot mechanism 200, and the belt feeding structure 300 can convey the edge banding tape to the side edge; as shown Figure 1 、 2 As shown, the color supply mechanism 400 includes a first tank body 410, a second tank body 420 and a quantitative structure 430. The liquid outlet of the first tank body 410 and the liquid outlet of the second tank body 420 are both connected to the glue pot mechanism 200. The quantitative structure 430 can adjust the liquid output of the first tank body 410 and the liquid output of the second tank body 420 according to the color of the edge banding.

[0057] By providing a first tank body 410 and a second tank body 420, the first tank body 410 and the second tank body 420 can pre-store light-colored glue and dark-colored glue respectively, and by providing a quantitative structure 430, the quantitative structure 430 can adjust the liquid output of the first tank body 410 and the liquid output of the second tank body 420 according to the color of the edge banding, that is, adjust the ratio of light-colored glue to dark-colored glue, and then after the light-colored glue and the dark-colored glue enter the glue pot mechanism 200, the color of the mixture of the light-colored glue and the dark-colored glue can be the same as the color of the edge banding, so that after the feeding structure 300 sticks the edge banding to the side wall of the board, the color of the edge band is the same as the color of the glue, avoiding the unsightly appearance of the board after the edge banding is pressed.

[0058] Specifically, the color of the light-colored glue may be white, and the color of the natural-colored glue may be a natural color other than white.

[0059] While working:

[0060] S1: Obtain the color of the edge band on the tape feeding structure 300;

[0061] S2: The first tank 410 delivers light-colored glue to the glue pot mechanism 200, and the second tank 420 delivers dark-colored glue to the glue pot mechanism 200. The metering mechanism 430 adjusts the liquid output of the first tank 410 and the liquid output of the second tank 420 according to the color of the edge banding, so that the color of the light-colored glue and the dark-colored glue in the glue pot mechanism 200 after mixing is the same as the color of the edge banding;

[0062] S3: the plate conveyor 100 drives the plate to move forward;

[0063] S4: When the plate passes through the glue pot mechanism 200, the glue pot mechanism 200 applies the mixed glue to the side of the plate;

[0064] S5: When the plate passes through the belt feeding structure 300, the belt feeding structure 300 sticks the edge banding tape on the side.

[0065] Specifically, if Figure 3 As shown, the glue pot mechanism 200 includes a glue roller 210 and a liquid storage box 220. The liquid storage box 220 is connected to the first tank body 410 and the second tank body 420. The liquid storage box 220 transports glue to the outer surface of the glue roller 210 through a pipeline.

[0066] During operation, the first tank body 410 transports light-colored glue to the liquid storage box 220, and the second tank body 420 transports dark-colored glue to the liquid storage box 220. The light-colored glue and the dark-colored glue are mixed in the liquid storage box 220. When the plate passes through the glue coating roller 210, the glue coating roller 210 applies the glue on its surface to the side of the plate.

[0067] It is understandable that when the light-colored glue and the dark-colored glue are conveyed to the glue coating roller 210 , the glue coating roller 210 mixes the light-colored glue with the dark-colored glue.

[0068] It is conceivable that the glue pot mechanism 200 may also adopt an existing glue pot mechanism 200 .

[0069] Specifically, the plate conveyor 100 may be a conveyor belt, or may refer to the plate conveying structure of an existing edge banding machine.

[0070] In some embodiments of the present invention, Figure 2 As shown, the color supply mechanism 400 also includes a storage box 440, in which a rotatable stirring blade (not shown) is installed. The liquid outlet of the first tank body 410 is connected to the storage box 440 through the first pipe 401, and the liquid outlet of the second tank body 420 is connected to the storage box 440 through the second pipe 402. The storage box 440 is connected to the glue pot mechanism 200 (liquid storage box 220) through the third pipe 403. The quantitative structure 430 can adjust the flow rate of the first pipe 401 and the flow rate of the second pipe 402 according to the color of the edge banding.

[0071] By providing the storage box 440 and the stirring blades, the light-colored glue and the dark-colored glue can be mixed in the storage box 440 in advance and then transported to the glue pot mechanism 200 after mixing, so that the color of the mixed glue is more matched with the color of the edge banding.

[0072] During operation, the first tank body 410 transports the light-colored glue to the storage box 440 through the first pipe 401, and the second tank body 420 transports the dark-colored glue to the storage box 440 through the second pipe 402. The stirring blades in the storage box 440 stir the light-colored glue and the dark-colored glue. After stirring, the storage box 440 transports the glue to the glue pot mechanism 200 through the third pipe 403.

[0073] In a further embodiment of the present invention, Figure 2 As shown, the quantitative structure 430 of the first embodiment includes a pump 431 and a quantitative valve 432 , and both the first pipeline 401 and the second pipeline 402 are provided with the pump 431 and the quantitative valve 432 sequentially arranged along the liquid movement direction.

[0074] By providing a pump 431 , the glue can be pumped to the storage box 440 ; by providing a metering valve 432 , the mixing ratio of the light-colored glue and the dark-colored glue can be accurately controlled.

[0075] In some embodiments of the present invention, Figure 4 、 5 As shown, the belt feeding structure 300 includes:

[0076] The support base 310 has a plurality of conveying channels 311 spaced apart along the front-to-back direction;

[0077] The switching mechanism 320 is installed on the support base 310. The switching mechanism 320 can drive the edge banding in one of the conveying channels 311 to move and move it to the side.

[0078] By providing multiple conveying channels 311, the multiple conveying channels 311 can respectively place edge banding tapes of different colors, and by providing a switching mechanism 320, edge banding tapes of different colors can be affixed to the side edges of the board according to actual needs; and because a color supply mechanism 400 is provided, the color of the glue on the glue pot mechanism 200 can match edge banding tapes of different colors, thereby improving the practicality of the edge banding machine.

[0079] For example, the color of the edge banding on the first conveying channel 311 (α) is off-white, and the color of the edge banding on the second conveying channel 311 (β) is yellow. During operation, when it is necessary to press the off-white edge banding, the switching mechanism 320 drives the edge banding on the first conveying channel 311 (α) to move and move it to the side, while the switching mechanism 320 does not drive the edge banding on the second conveying channel 311 (β) to move. Conversely, when it is necessary to press the yellow edge banding, the switching mechanism 320 does not drive the edge banding on the first conveying channel 311 (α) to move, but the switching mechanism 320 drives the edge banding on the second conveying channel 311 (β) to move and move it to the side.

[0080] In a further embodiment of the present invention, Figure 5 、 6 ,7,

[0081] The switching mechanism 320 includes:

[0082] The fixed roller 321 is rotatably mounted on the support base 310 and is located between two adjacent conveying channels 311;

[0083] A movable roller 322 is installed on both the front and rear sides of the fixed roller 321, and the edge band is located between the movable roller 322 and the fixed roller 321;

[0084] The first driving device 323 is installed on the support base 310 and is used to drive the fixed roller 321 to rotate;

[0085] The second driving device 324 is installed on the support base 310 . The second driving device 324 can drive the movable roller 322 to move closer to or away from the fixed roller 321 .

[0086] The switching mechanism 320 adopts the above structure, which makes the switching mechanism 320 simple in structure. When the edge band needs to be switched, it is only necessary to drive the movable roller 322 located in front of the fixed roller 321 or the movable roller 322 located behind the fixed roller 321 to abut against the fixed roller 321.

[0087] Since a plurality of conveying channels 311 are provided, such as Figure 5 、 6 7 , taking two adjacent conveying channels 311 as an example, and respectively defined as a first conveying channel 311 (α) and a second conveying channel 311 (β), during operation, the first driving device 323 drives the fixed roller 321 to rotate, and the off-white edge banding enters the first conveying channel 311 (α) under the action of external equipment or manual labor, so that the off-white edge banding is located between the fixed roller 321 and the movable roller 322 located in front of the fixed roller 321, and the yellow edge banding enters the second conveying channel 311 (β) under the action of external equipment or manual labor, so that the yellow edge banding is located between the fixed roller 321 and the movable roller 322 located behind the fixed roller 321;

[0088] When it is necessary to convey an off-white edge banding, the quantitative structure 430 adjusts the liquid output of the first tank 410 and the liquid output of the second tank 420 respectively according to the color of the edge banding, so that the glue discharged from the glue pot mechanism 200 is off-white. The glue pot mechanism 200 applies the glue to the side of the plate, and the second driving device 324 drives the movable roller 322 located in front of the fixed roller 321 to move backward, thereby clamping the off-white edge banding between the movable roller 322 and the fixed roller 321 located in front of the fixed roller 321. Due to the rotation of the fixed roller 321, the fixed roller 321 drives the off-white edge banding to move along the first conveying channel 311 (α), so that the off-white edge banding is attached to the side of the plate under the drive of the fixed roller 321;

[0089] When the yellow edge banding needs to be conveyed, the second driving device 324 drives the movable roller 322 located behind the fixed roller 321 to move forward, and then clamps the yellow edge banding between the movable roller 322 located behind the fixed roller 321 and the fixed roller 321, so that the fixed roller 321 drives the yellow edge banding to move along the second conveying channel 311 (β) and stick to the side of the plate.

[0090] It is understandable that the fixed roller 321 can rotate around its own axis, but the axis cannot move, that is, the fixed roller 321 is fixed to the support base 310, but can rotate around its own axis.

[0091] It is understandable that the movable roller 322 can rotate around its own axis, but the axis cannot move, that is, the movable roller 322 is fixed on the support base 310, but can rotate around its own axis.

[0092] Specifically, multiple conveying channels 311 are arc-shaped, and the discharge ends of multiple conveying channels 311 converge at one point of the support seat 310. Therefore, no matter which conveying channel 311 outputs the edge banding, the edge banding will be output at the same place, which is convenient for sticking the edge banding on the side of the board.

[0093] In a further embodiment of the present invention, Figure 5 As shown, it also includes a belt stop device 500, which includes a first pressure roller 510 and a second pressure roller 520. The first pressure roller 510 is located to the right of the fixed roller 321, and the second pressure roller 520 is located to the right of the movable roller 322. The edge banding is located between the first pressure roller 510 and the second pressure roller 520. The second pressure roller 520 can move toward or away from the first pressure roller 510.

[0094] By providing the belt stop device 500 , when one of the edge bands is conveyed, the other edge bands can be clamped by the first pressing roller 510 and the second pressing roller 520 to prevent the other edge bands from moving and thus avoid affecting the movement of one of the edge bands.

[0095] Specifically, the first pressing roller 510 and the second pressing roller 520 can both rotate around their own axes.

[0096] In a further embodiment of the present invention, Figure 7 、 8 As shown, the second driving device 324 includes:

[0097] Cylinder 325, one end of the cylinder 325 is hinged to the support base 310;

[0098] The rocker clamping block 326 includes a fixed portion 3261 and three extension portions 3262. The fixed portion 3261 is rotatably mounted on the support base 310. The three extension portions 3262 are mounted on the side walls of the fixed portion 3261 and are spaced apart along the circumference of the fixed portion 3261. The three extension portions 3262 are hingedly connected to the other end of the cylinder 325, the movable roller 322, and the second pressure roller 520, respectively.

[0099] The cylinder 325 can drive the rocker clamping block 326 to rotate between the first position and the second position;

[0100] In the first position, the movable roller 322 is close to the fixed roller 321 , and the second pressing roller 520 is away from the first pressing roller 510 ;

[0101] like Figure 8 As shown, in the second position, the movable roller 322 is away from the fixed roller 321 , and the second pressing roller 520 is close to the first pressing roller 510 .

[0102] By providing the cylinder 325 and the rocker clamping block 326, when the edge band is not driven to move, the cylinder 325 drives the rocker clamping block 326 to the second position, the movable roller 322 moves away from the fixed roller 321, and the second pressing roller 520 approaches the first pressing roller 510, so that the fixed roller 321 does not drive the edge band to move, and the second pressing roller 520 and the first pressing roller 510 jointly clamp the edge band to prevent the edge band from moving in the conveying channel 311;

[0103] When driving the edge banding to move, the cylinder 325 drives the rocker clamping block 326 to the first position, the moving roller 322 approaches the fixed roller 321, and the second pressure roller 520 moves away from the first pressure roller 510, so that the fixed roller 321 drives the edge banding to move. The second pressure roller 520 and the first pressure roller 510 do not clamp the edge banding together, so that the edge banding can move in the conveying channel 311.

[0104] It is understandable that if Figure 8As shown, the three extension parts 3262 are respectively connected to the other end of the cylinder 325, the second pressure roller 520, and the moving roller 322. The cylinder drives the fixed part 3261 to rotate on the support seat 310 through the extension part 326 connected thereto, so that the fixed part 3261 rotates between the first position and the second position. When the fixed part 3261 rotates to the second position, the second pressure roller 520 abuts against its corresponding first pressure roller 510 (not shown in the figure). When the fixed part 3261 rotates to the first position, the moving roller 322 abuts against its corresponding fixed roller 321 (as shown in the figure). Figure 8 shown).

[0105] Since there are multiple conveying channels 311, there are also multiple switching mechanisms 320, second driving devices 324 and belt stop devices 500. Therefore, when one of the conveyor belts is driven, the other conveyor belts are clamped and fixed under the action of the belt stop device 500, that is, only one conveyor belt is conveyed and the other conveyor belts are fixed.

[0106] In some embodiments of the present invention, Figure 5 As shown, limit shafts 312 are installed on both sides of the conveying channel 311 , and height limit members 313 that can move up and down are installed on the two limit shafts 312 . The height limit members 313 are located above the conveying channel 311 .

[0107] The height limiting member 313 is provided to prevent the conveyor belt from moving upward.

[0108] In a further embodiment of the present invention, Figure 1 As shown, the tape storage device 600 is also included, and the tape storage device 600 includes:

[0109] Rack 610;

[0113] The quantitative structure 430 of the second embodiment includes a first storage cylinder 433, a second storage cylinder 434, an extrusion structure 435, a first opening and closing element 436, a second opening and closing element 437 and a metering pump 438;

[0114] The liquid outlet of the first tank body 420, the first inlet 4331 of the first storage cylinder 433, the first outlet 4332 of the first storage cylinder 433, the second inlet 4341 of the second storage cylinder 434, the second outlet 4342 of the second storage cylinder 434 and the feed end of the extruder 404 are connected in sequence through pipelines, the discharge end of the extruder 404 is connected to the glue pot mechanism 200, the extrusion structure 435 is installed on the first storage cylinder 433, the first opening and closing element 436 is installed on the first inlet 4331, and the second opening and closing element 437 is installed on the first outlet 4332. Multiple second tank bodies 420 are respectively connected to the second storage cylinder 434 through multiple fourth pipelines 439, and each fourth pipeline 439 is provided with a metering pump 438.

[0115] The quantitative structure 430 adopts the above structure to make the mixed glue closer to the color of the edge banding, with high accuracy.

[0116] It is understandable that the plurality of second tanks 420 may store pigments of different colors in advance. For example, if there are three second tanks 420 , the three second tanks 420 may store red pigment, green pigment, and blue pigment respectively.

[0117] While working:

[0118] S10: Obtain the color of the edge band on the tape feeding structure 300;

[0119] S20: The second opening and closing element 437 closes the first outlet 4332, and the first opening and closing element 436 opens the first inlet 4331, and the white glue in the first tank 420 is transported to the first storage cylinder 433;

[0120] S30: After the first tank 420 has finished delivering the pigment, the first opening and closing element 436 closes the first inlet 4331, and the second opening and closing element 437 opens the first outlet 4332. The extrusion mechanism 435 squeezes the white glue in a proportion corresponding to the color of the edge band into the second storage cylinder 434. One or more metering pumps 438 are activated according to the color of the edge band to deliver the pigment in a proportion corresponding to the color of the edge band into the second storage cylinder 434.

[0121] S40 , the extruder 404 mixes the white glue and the pigment, and then transports the mixed mixture to the glue pot mechanism 200 .

[0122] Specifically, the fourth pipe 439 extends into the second storage cylinder 434, thereby injecting the pigment into the middle of the glue and avoiding injecting it into the edge of the glue. This will make the mixed glue closer to the color of the edge band or easier to mix.

[0123] Specifically, the extrusion structure 435 includes a slide plate that can be raised and lowered, a screw rod that drives the slide plate to move up and down, and a servo motor that drives the screw rod to rotate. The slide plate is located in the first storage cylinder 433 .

[0124] During operation, the servo motor drives the screw to rotate, and the screw drives the slide to move up and down.

[0125] Specifically, the first opening and closing element 436 and the second opening and closing element 437 can both be valves, for example, cylinder valves.

[0126] The working method of the automatic edge banding machine according to the second embodiment of the present invention includes: the working method of the automatic edge banding machine according to the first embodiment includes:

[0127] S1: Obtain the color of the edge band on the tape feeding structure 300;

[0128] S2: The quantitative structure 430 adjusts the liquid output of the first tank 410 and the liquid output of the second tank 420 according to the color of the edge banding, so that the color of the glue in the glue pot mechanism 200 is the same as the color of the edge banding;

[0129] S3: The plate conveyor 100 drives the plate to move;

[0130] S4: The glue pot mechanism 200 applies glue to the side of the plate;

[0131] S5: The tape feeding structure 300 sticks the edge banding tape on the side.

[0132] By providing the above-mentioned working method and adopting the automatic edge banding machine of the first embodiment, the automatic edge banding machine can automatically select edge banding tapes and glue of the same color.
