Description

Technical Field

[0001] The invention belongs to the technical field of plate edge banding, and in particular relates to an edge banding machine. Background Art

[0002] In the process of furniture manufacturing, edge banding machines are needed to band the outer edges of the boards to improve the performance of the boards. After the edge banding, edge bands will be reserved at both ends of the boards. The boards also need to be edge banded by edge banding machines to cut the two ends of the edge bands so that the edge bands are completely flush with the two ends of the boards.

[0003] In the prior art, the edge banding machine is provided with a trimming device for trimming the edges. In the current conventional edge banding machine, the trimming device adopts a 45° bevel cutting method for cutting, that is, the plate is transported in the horizontal direction, and the cutting movement direction of the trimming device is at a 45° angle to the transport direction of the plate, and cutting is performed from top to bottom.

[0004] In this way, when the edge banding machine is performing the end-aligning process, the saw blade of the end-aligning device and the backing plate that abuts against the plate during cutting are driven to move at the same time. The plate is transported in the horizontal direction, abutted against the plate by the backing plate, and then moves forward synchronously with the plate, while the end-aligning device moves downward, and the saw blade cuts the edge band 30. Since the saw blade and the backing plate are driven to move at the same time, that is, when the backing plate abuts against the plate and the saw blade moves downward to cut the edge band, the backing plate also moves downward, thereby causing a vertical displacement with the plate; the abutting relationship between the backing plate and the plate itself has a force, and the force generated by the downward movement of the backing plate causes scratches on the side of the plate that contacts the backing plate. If the side has been edge-banded, scratches will be left on the smooth edge band, affecting the quality of the plate.

[0005] Therefore, the existing technology needs to be improved and developed. Summary of the invention

[0048] like Figures 1 to 3 As shown, an edge banding machine according to an embodiment of the present application includes a frame 600, an edge banding device 700 and an end trimming device 100; the frame 600 is provided with a conveying trough 610 for conveying a plate 601; the edge banding device 700 and the end trimming device 100 are sequentially connected to the frame 600 along a conveying direction L of the plate in the conveying trough 610; the end trimming device 100 includes an end trimming bracket 160 and an end trimming assembly 101, and the end trimming assembly 101 is connected to the end trimming bracket 160; the end trimming assembly 101 includes: a cutting assembly 120 for cutting the end of the edge band; a shifting assembly 120 for shifting the edge band to the end of the edge band; The moving component 150 is used to drive the trimming assembly 101 to reciprocate along the conveying direction L of the plate; the trimming feed driving component 140 is connected to the above-mentioned cutting component 120 to drive the cutting component 120 to move to the cutting position; the saw blade reset component 130 is connected to the above-mentioned moving component 150 and to the above-mentioned trimming feed driving component 140 to drive the above-mentioned cutting component 120 to move to cut the end of the edge banding; the support plate 110 is movably connected to the above-mentioned moving component 150 to abut against the plate 601 during cutting and avoid the plate 601 after cutting.

[0049] When the plate 601 completes the edge banding process and enters the end trimming process, the moving component 150 drives the end trimming assembly 101 to move and track the plate 601 along the conveying direction L of the plate, and abuts against the plate 601 through the backing plate 110. At the same time, the end trimming feed drive 140 drives the cutting assembly 120 to move to the cutting position, and finally the saw blade reset component 130 drives the cutting assembly 120 to move for cutting. During operation, the end trimming assembly drives the movement of the cutting assembly separately through the end trimming feed drive and the saw blade reset component on the basis of the same moving component, so that the cutting work of the cutting assembly and the abutting work of the backing plate are relatively independent and do not affect each other. In addition, the end trimming assembly moves horizontally during operation, avoiding displacement of the backing plate and the plate 601 in the vertical direction, thereby avoiding scratches on the side of the plate 601 in contact with the backing plate, and ensuring the stability of the quality of the plate 601.

[0050] like Figure 2 As shown, in some preferred embodiments, the trimming assembly 101 is provided with two groups, which cut the two ends of the edge band respectively, one group of structures is collectively referred to as the trimming assembly 100a, and the other group of structures is collectively referred to as the tail cutting assembly 100b. The plate passes through the trimming assembly 100a and the tail cutting assembly 100b in turn along the conveying direction L, and the front end and the rear end of the edge band are cut in turn. The trimming assembly 100a and the tail cutting assembly 100b are relatively connected to the trimming bracket 160, and the trimming assembly 100a and the tail cutting assembly 100b both include the cutting assembly 120, the moving assembly 150, the trimming feed drive 140, the saw blade reset member 130 and the support plate 110. Therefore, a trimming device is provided on the edge banding machine, which can successively complete the trimming processing of the two ends of the edge band, simplify the structure of the edge banding machine, reduce the manufacturing cost, and improve the processing efficiency of the plate.

[0051] Specifically, the above-mentioned moving assembly includes a moving cylinder 151, a moving seat 152 and a moving guide rail 153. The moving cylinder 151 is installed on the head trimming bracket 160. The movable end of the moving cylinder 151 is connected to the moving seat 152 to drive the moving seat 152 to move. The moving seat 152 is installed on the moving guide rail 153. The two ends of the moving guide rail 153 can be installed on the head trimming bracket 160, or directly installed on the edge banding machine. The specific installation method is selected according to the actual use situation. Specifically, the head trimming moving guide rail 153a supporting the movement of the head trimming assembly 100a and the tail trimming moving guide rail 153b supporting the movement of the tail trimming assembly 100b are arranged head to tail. In order to make the structure of the device compact and save installation space, the two moving cylinders 151 are arranged in opposite directions. The head cutting moving cylinder driving the head cutting assembly 100a is extended to be arranged parallel to the tail cutting moving guide rail 153b, and the tail cutting moving cylinder 151b driving the tail cutting assembly 100b is extended to be arranged parallel to the head cutting moving guide rail 153a. The above-mentioned support plate 110, cutting assembly 120, saw blade reset member 130 and end feed drive member 140 are installed on the corresponding moving seat 152.

[0052] Specifically, the cutting assembly 120 includes a cutting motor 121 and a saw blade 122 , and the saw blade 122 is fixedly connected to the output shaft of the cutting motor 121 .

[0053] Specifically, the backing plate 110 is mounted on the side of the moving seat 152 through the first mounting plate 171; the saw blade reset member 130 is mounted on the top of the moving seat 152, and the saw blade reset member 130 is installed with a second mounting plate 172 to install and drive the flush cutter driving member 140 and the cutting assembly 120 to move. Specifically, the flush cutter driving member 140 and / or the saw blade reset member 130 can be a cylinder.

[0054] like Figure 2 , 3As shown, in some embodiments, the feeding movement and cutting movement of the cutting assembly 120 are also matched with the flush feed guide rail 141 and the saw blade reset guide rail 131 respectively. Specifically, the second mounting plate 172 is arranged in an inverted L shape, and a vertical side panel of the second mounting plate 172 is opposite to the first mounting plate 171, the saw blade reset guide rail 131 is arranged on the first mounting plate 171, and a matching saw blade reset slider 132 is arranged on a vertical side panel of the second mounting plate 172, and the flush feed guide rail 141 is arranged on a horizontal side panel of the second mounting plate 172, and a matching flush feed slider 142 is arranged below the cutting motor 121. Therefore, when the saw blade reset member 130 drives the cutting assembly 120 to move downward in direction F for cutting, the cutting assembly 120 moves along the saw blade reset guide rail 131. Similarly, when the flush feed drive member 140 drives the cutting assembly 120 to move horizontally in direction E to the cutting position, the cutting assembly 120 moves along the flush feed guide rail 141.

[0055] like Figure 2 As shown, in some preferred embodiments, the above-mentioned support plate 110 has a support surface 112 for supporting the plate 601, and the support surface 112 is perpendicular to the plate 601. Thus, the support surface is in full contact with the side of the plate, and can better support the plate to stably cut the edge banding strip.

[0056] like Figure 2 , 3 As shown, in some preferred embodiments, the above-mentioned support plate 110 is connected to the above-mentioned moving assembly 150 through a support rail 113 and a support slider 114, and the extension direction of the support rail 113 is relatively inclined with the conveying direction L of the plate; the support plate 110 is connected to a support cylinder 111 to drive its movement. Therefore, the support plate will not shift and rub against the side of the plate when it is against the plate and leaves the plate, so as to avoid scratching the side of the plate.

[0057] Specifically, the abutment guide rail 113 is installed on the outer side of the first mounting plate 171 , and the abutment slider 114 is connected to the abutment plate 110 ; the abutment cylinder 111 is installed on the outer side of the first mounting plate 171 , and the movable end of the abutment cylinder 111 is connected to the abutment plate 110 . More specifically, the abutment guide rail 113a of the head cutting assembly 100a is arranged to be tilted downward along the conveying direction L of the plate. When the plate 601 is conveyed to the head cutting assembly 100a, the support plate 110a faces the plate 601 at the front end of the plate 601, and moves upward along the direction G1 to abut against the plate 601. Driven by the movable seat 152, the plate 601 pushes the support plate 110a to move forward synchronously; the abutment guide rail 113b of the tail cutting assembly 100b is arranged to be tilted upward along the conveying direction L of the plate. After the plate 601 is conveyed to the tail cutting assembly 100b, the support plate 110b follows the plate 601 at the rear end of the plate 601, and moves upward along the direction G2 to abut against the plate 601. Driven by the movable seat 152, the support plate 110b pushes the plate 601 to move forward synchronously.

[0058] In actual use and installation, due to manual installation, errors are inevitable, such as the blade surface of the saw blade is not parallel to the side of the board. The occurrence of this error will cause the cut edge of the edge banding to be uneven with the edge of the board. Figure 3 As shown, in order to solve the above problem, in some preferred embodiments, the cutting motor 121 is connected to an angle adjustment plate 123, so that the angle of the cutting motor can be adjusted to adapt to the actual use environment, and then the cutting angle of the saw blade can be adjusted to ensure that the cutting edge of the edge banding strip is flush with the edge of the board.

[0059] Furthermore, in some preferred embodiments, the angle adjustment plate 123 is matched with an adjustment base plate 124, the angle adjustment plate 123 is stacked with the adjustment base plate 124, and connected by fixing bolts; the angle adjustment plate 123 is provided with an arc-shaped adjustment groove, and the adjustment base plate 124 is provided with an adjustment guide column, and the adjustment guide column is arranged in the arc-shaped adjustment groove. Therefore, when adjusting the angle, unscrew the fixing bolt, rotate the angle adjustment plate 123 along the arc-shaped adjustment groove to ensure the accuracy of the adjustment, and tighten the fixing bolt to fix it after determining the position, and the adjustment is completed, and the adjustment work is simple and fast. As a preferred solution, two adjustment guide columns are provided.

[0060] Specifically, the cutting motor 121 is installed on the angle adjustment plate 123 through the motor seat 128, the adjustment base plate 124 is fixedly connected to the driving end of the cutter feed drive 140 (specifically, the movable end of the feed drive cylinder in this embodiment), and the above-mentioned cutter feed slider 142 is installed at the bottom of the adjustment base plate 124.

[0061] In some embodiments, the head cutting assembly 100a and / or the tail cutting assembly 100b can be matched with a plate sensing switch for sensing the conveying stroke of the plate, and transmitting information to control the support plate 110 to press against the plate; the head cutting assembly 100a and / or the tail cutting assembly 100b can be matched with a cutting sensing switch for sensing the conveying stroke of the plate, and transmitting information to control the saw blade 122 to move and cut the edge strip.

[0062] Specifically, Figure 1 As shown, the frame 600 is provided with an upper crossbeam 620 and a lower crossbeam 630, wherein the lower crossbeam 630 is fixedly connected to the frame 600, the upper crossbeam 620 is arranged above the lower crossbeam 630, and there is a gap between the upper crossbeam 620 and the lower crossbeam 630, and the gap forms the above-mentioned conveying trough 610. Specifically, the conveying trough 610 is provided with a circularly rotating chain block for conveying the plate, and the rotation drive of the chain block can adopt existing technical means, which will not be repeated here. In some embodiments, the upper crossbeam 620 is connected to the frame 600 so that it can move up and down relatively, thereby, by moving the upper crossbeam up and down to adjust the height of the conveying trough, it can adapt to plates of different specifications (thickness). In some embodiments, the up and down movement of the upper crossbeam can be driven by existing technical means, such as the technical means of motor drive and worm gear structure transmission. Specifically, the motor may be a gear reduction motor having a worm gear structure and fixedly connected to the upper crossbeam, and the worm gear structure is fixedly connected to the frame 600 and meshes with the worm gear structure.

[0063] Specifically, Figure 1 As shown, the edge banding device 700 further includes a pre-milling mechanism for pre-milling the plate, a belt feeding mechanism 710 for inputting the edge banding, a gluing mechanism 720 for gluing the plate, a cutting mechanism 730 for cutting the edge banding, a pressing mechanism 740 for pressing the edge banding and the plate, and a polishing mechanism. The pre-milling mechanism, belt feeding mechanism 710, gluing mechanism 720, cutting mechanism 730, pressing mechanism 740 and polishing mechanism can be arranged by existing technical means, and will not be described in detail herein.

[0064] like Figure 1As shown, in some preferred embodiments, the belt feeding mechanism 710 includes a double-feeding assembly 750, which is used to assemble two edge bands of different specifications, and automatically input one of the edge bands for edge banding according to the edge banding requirements. Specifically, the double-feeding assembly 751 includes a first input track 751 and a second input track 752 arranged in parallel, and a transmission pressure wheel 753 is connected between the adjacent sides of the first input track 751 and the second input track 752, and the transmission pressure wheel 753 is used to provide power to input the edge band, and the first input track 751 and the second input track 752 are separated. The side is provided with an auxiliary pressure wheel 754, and the auxiliary pressure wheel 754 is used to move toward the transmission pressure wheel 753 and press the edge band together with the transmission pressure wheel 753 for conveying, and follow the rotation at the same time. The two auxiliary pressure wheels 754 and the transmission pressure wheel 753 are arranged in the same straight line. Therefore, when it is necessary to input one of the edge bands, the corresponding auxiliary pressure wheel 743 is controlled to move toward the transmission pressure wheel 753, and then press the edge band for conveying. Specifically, the transmission pressure wheel 753 is connected to the belt-entry driving motor for driving, and the auxiliary pressure wheel 754 is connected to the belt-entry cylinder for driving. In order to make the structure compact, the belt-entry driving motor and the two belt-entry cylinders are arranged below the first input track 751 and the second input track 752. The rotating shaft to which the auxiliary pressure wheel 754 is rotatably connected passes through the bottom of the first input track 751 / the second input track 752 and is connected to the telescopic end of the belt-entry cylinder. The rotating shaft to which the transmission pressure wheel 753 is fixedly connected passes through the bottom of the first input track 751 / the second input track 752 and is connected to the output shaft of the belt-entry driving motor.

[0065] In some embodiments, the above-mentioned belt feeding assembly 750 also includes a placement structure 756 for the edge banding, which is provided with a placement shaft. The edge banding is placed in a circle on the placement shaft and then led to the first input track 751 / the second input track 752 for input. During the conveying process, the circled edge banding rotates on the placement shaft.

[0066] In some preferred embodiments, the placement structure 756 is provided with a sensing device (not shown in the figure) at the outlet end where the edge band is led out. The sensing device is used to detect whether there is an edge band being transported, that is, to detect whether the edge band on the placement structure has been transported. In a more preferred embodiment, the reactor is also equipped with an alarm. When the sensing device does not detect a signal, the information is transmitted to the alarm to notify the staff to handle it. In this way, the belt feeding work can be completed automatically without the need for personnel to be on duty all the time, which saves labor to a certain extent. Specifically, the sensing device can be a photoelectric sensor.

[0067] After edge banding, some boards will be finely trimmed, that is, the long edges on both sides of the edge banding will be chamfered to improve the aesthetics of the board and enhance its market competitiveness. Figures 4 to 6As shown, in some preferred embodiments, the edge banding machine further includes a finishing device 200, which is connected to the frame 600 and is arranged in front of the trimming device along the conveying direction L of the plate in the conveying trough. Thus, the edge banding machine is connected to the processing line for edge banding the plate to perform finishing processing, so that the finishing processing of the plate after edge banding is realized, and the continuous processing line improves the processing efficiency of the plate.

[0068] Specifically, the above-mentioned finishing device 200 includes a finishing bracket 201 and a finishing assembly 210, and the finishing assembly 210 is connected to the finishing bracket 201; the finishing assembly 210 is provided with a finishing station for chamfering the long side of the edge banding; the finishing station is provided with a first positioning member 211, and the first positioning member 211 is used to position the side of the plate with the edge banding to determine the working position between the finishing knife 213 and the plate, thereby ensuring the stability of the plate finishing during finishing; the first positioning member 213 is connected to a servo adjustment motor 215, and the servo adjustment motor 215 is connected to a PLC system; the PLC system adjusts the position of the first positioning member 213 through the servo adjustment motor 215 according to the thickness of the edge banding. Specifically, the PLC system has an adjustment module, which has matching data. Edge bands of different thicknesses have corresponding control data. The thickness data of the edge bands is input into the PLC system, and the adjustment module outputs corresponding control data based on the thickness data, and commands the servo adjustment motor 215 to drive the first positioning member 213 to make a corresponding displacement.

[0069] The servo control motor is commanded by the PLC system to improve the accuracy of the position adjustment of the first positioning part. Compared with manual adjustment, the adjustment error of the refiner is improved from ±0.2mm to ±0.02mm, and the adjustment accuracy is increased by 90%, which is greatly improved.

[0070] Specifically, the output shaft of the servo adjustment motor 215 is fixedly connected to a screw rod, which is threadedly connected to an adjustment seat. The first positioning member 211 is connected to the adjustment seat via a first mounting arm 2151. Thus, the servo adjustment motor drives the screw rod to rotate, driving the adjustment seat to reciprocate along the screw rod in the horizontal direction E, thereby driving the first positioning member to reciprocate along the horizontal direction E for adjustment.

[0071] Specifically, the finishing station is also provided with a finishing knife 213 and a second positioning member 212 for positioning the top (bottom) surface of the plate. There is a working gap between the second positioning member 212 and the first positioning member 211, and the finishing knife 213 is tiltedly arranged in the working gap. The finishing knife 213 is connected to a finishing motor 214 to drive its rotation; the first positioning member 211 and the second positioning member 212 can rotate relative to the finishing device, so that the first positioning member and the second positioning member can rotate with the conveyance of the plate to avoid scratching the surface of the plate due to the mutual resistance of positioning. Specifically, the first positioning member 211 or the second positioning member 212 can be installed through a rotating shaft using a contoured disk to achieve rotation.

[0072] In actual work, part of the sheet material will extend from the conveying trough of the edge banding machine and enter the interior of the edge banding machine to facilitate edge banding and post-edge banding processing. During the conveying process, the sheet material will undergo a slight displacement change, causing a slight change in the size of the protruding part, which in turn affects the finishing work.

[0073] like Figure 5 , 6 As shown, in some preferred embodiments, the finishing assembly 210 further includes a floating fine-tuning component 220, and the finishing assembly is connected to the finishing bracket 201 through the floating fine-tuning component 220, so that the finishing assembly 210 can be displaced along the horizontal direction E. Therefore, through the floating fine-tuning component 220, the finishing assembly 210 can adapt to slight changes in the extended size of the plate. For example, when the size of the extended part becomes larger, the finishing assembly 210 can retreat along the horizontal direction E, so that the first positioning member 211 can always be against the side of the plate to position the plate, ensuring the smooth progress of the finishing work.

[0074] In some preferred embodiments, the floating fine-tuning assembly 220 includes a fixing member 230 and a sliding member 240, the fixing member 230 and the sliding member 240 are connected to each other in a relative sliding manner along the horizontal direction E, a first fine-tuning spring 250 is pressed against the fixing member 230 and the sliding member 240, the first fine-tuning spring 250 is arranged on a side of the fixing member 230 and the sliding member 240 away from the first positioning member, and its deformation direction is parallel to the horizontal direction E, and the first positioning member 211, the second positioning member 212 and the finishing knife 213 are connected to the sliding member 240. Thus, by utilizing the elasticity of the first fine-tuning spring to adapt to the slight change in the extended size of the plate, the finishing assembly can slide along the fixing member as the extended size of the plate changes, so that the first positioning member can keep against the side of the plate in the horizontal direction E, thereby ensuring the stability of the finishing assembly.

[0075] like Figure 5As shown, in some embodiments, the sliding member 240 includes a fixedly connected mounting plate 241 and a first sliding column 242, wherein the mounting plate 241 is used to mount the first positioning member 200a, the second positioning member 212b and the finishing knife 213, and the fixing member 230 is provided with a guide hole, and the sliding member 230 is connected by the first sliding column 242 passing through the guide hole of the fixing member 230, and moves along the guide hole. As a preferred embodiment, the first sliding column 242 is provided with two parallel first sliding columns 242, and the two ends of the two first sliding columns 242 are fixedly connected by the finishing connection plate 243. Specifically, the servo adjustment motor 215, the finishing motor 214, and the second positioning member 212 are connected to the mounting plate 241 respectively.

[0076] In some embodiments, the mounting plate 241 includes a mounting portion 2411 and a connecting portion 2412, wherein the connecting portion 2412 is protrudingly disposed at both ends of the mounting portion 2411 and is used to connect with the first sliding column 242, the first positioning member 211, the second positioning member 212 and the finishing knife 213 are connected to the mounting portion 2411, and the two connecting portions 2412 are spaced apart from the two bosses 272. Thus, the sliding member can provide sufficient mounting positions to connect with the first positioning member, the second positioning member and the finishing knife through the mounting portion, and the distance between the two bosses can be shortened while meeting the motion travel requirements of the upper finishing mechanism in the horizontal direction E, so that the structure of the finishing device and the edge banding machine is more compact.

[0077] In some preferred embodiments, the first fine-tuning spring 250 is arranged on the outer side of the fine-tuning connecting plate 243 away from the fixing member 230, and is matched with an adjusting rod 251. One end of the adjusting rod 251 is sleeved with the first fine-tuning spring 250, and the other end passes through the fine-tuning connecting plate 243 and is fixedly connected to the fixing member 230. The first fine-tuning spring 250 is pressed tightly between the adjusting rod 251 and the fine-tuning connecting plate 243 of the sliding member 240. Therefore, the first fine-tuning spring is arranged on the outer side of the fine-tuning connecting plate, and the minimum distance between the fine-tuning connecting plate and the fixing member is reduced, so that the structure of the fine-tuning device is more compact.

[0078] In some preferred embodiments, the sliding member 240 is connected to a fine-finishing positioning cylinder 217, and the telescopic end of the fine-finishing positioning cylinder 217 performs telescopic movement relative to the fixing member 230, and presses against the fixing member 230 when extended, and the direction of the telescopic movement of the telescopic end of the fine-finishing positioning cylinder 217 is parallel to the horizontal direction E. Therefore, when the fine-finishing assembly does not need to work, the telescopic end extends to support the fixing member, and applies force to push the sliding member back in the opposite direction of the horizontal direction E, thereby driving the fine-finishing assembly to be retracted and leave the work station. Therefore, when the edge banding of the plate is completed and no fine-finishing treatment is required, the fine-finishing assembly can be retracted without affecting the transportation of the plate, without removing the fine-finishing device, or without another edge banding machine that does not include a fine-finishing device to work, the work is flexible, the operation is simple, and the production cost is reduced. Specifically, the fine repair positioning cylinder 217 is installed on the outer side of the fine repair connecting plate 243, and the fine repair connecting plate 243 is provided with a through hole corresponding to the telescopic end of the fine repair positioning cylinder 217. The telescopic end extends through the through hole to support the fixing member 230, and pushes the fine repair assembly 210 back to its original position. Therefore, the compactness of the structure of the fine repair device and the edge banding machine is not affected.

[0079] In some preferred embodiments, the finishing assembly 210 can be connected to the finishing bracket 201 so as to move up and down relatively. When the finishing assembly 210 performs chamfering on the upper long side of the edge band, the finishing assembly 210 moves up and down to adapt to the plates of different specifications (thicknesses) and to make adaptive movement to the adjustment error of the second positioning member 212; when the finishing assembly 210 performs chamfering on the lower long side of the edge band, the finishing assembly 210 moves up and down to make adaptive movement to the adjustment error of the second positioning member 212. Specifically, the finishing bracket 201 is provided with a second slide column 202, and the finishing assembly is connected to the second slide column 202 through a slide seat 216 and can move up and down along the second slide column 202; preferably, the second slide column 202 is provided with two parallel ones, and the slide seat 216 is provided with two corresponding guide holes. Specifically, the fixing member of the floating fine adjustment component 216 is connected to the slide seat 216.

[0080] In some embodiments, the fixing member 230 is integrally provided with the slide 216 to form a finishing mounting seat 270. Thus, the structure of the finishing device and the edge banding machine is simplified. Specifically, the middle of the finishing mounting seat 270 is provided with two vertically extending first guide holes 271 connected to the two second slide posts 202, and opposite bosses 272 are provided at both ends of the finishing mounting seat 270. The two bosses 272 are symmetrically provided with two transversely extending second guide holes 273 connected to the two first slide posts 242.

[0081] In some embodiments, the second positioning member 212 is connected to the sliding member 240 through an adjustment assembly, the adjustment assembly includes an adjustment hand wheel 261, an adjustment bolt 262, a fixed adjustment arm 263 and an adjustment mounting arm 264, and the second positioning member 212 is connected to the adjustment mounting arm 264. The fixed adjustment arm 263 and the adjustment mounting arm 264 are connected to the sliding member at intervals, wherein the fixed adjustment arm 263 is relatively far away from the plate 601. The fixed adjustment arm 263 is fixedly connected to the sliding member 240, and the adjustment mounting arm 264 is connected to the sliding member 240 so as to be relatively rotatable. One end of the adjustment bolt 262 is fixedly connected to the adjustment hand wheel 261, and the other end is threadedly connected to the fixed adjustment arm 263, and passes through the fixed adjustment arm 263 and is pressed against the adjustment mounting arm 264. A connecting bolt is also threadedly connected between the fixed adjustment arm 263 and the adjustment mounting arm 264, and a support spring is pressed against the adjustment mounting arm 264 at one end of the connecting bolt close to the adjustment mounting arm 264. The support spring is used to support or stabilize the adjustment mounting arm 264. Specifically, when the finishing assembly 210 performs chamfering on the upper long side of the edge banding, the support spring is mainly used to support the adjustment mounting arm 264, and when the finishing assembly 210 performs chamfering on the lower long side of the edge banding, the support spring is mainly used to stabilize the adjustment mounting arm 264. In this way, the position of the second positioning member is adjusted.

[0082] In some preferred embodiments, the finishing assembly 210 includes an upper finishing assembly 210a and a lower finishing assembly 210b, which are respectively installed on both sides of the finishing bracket 201, and are used to chamfer the upper long side and the lower long side of the edge band. In this way, the long sides of the upper and lower sides of the edge band can be chamfered. A set of finishing devices is provided on the edge banding machine to successively complete the finishing processing of the long sides of the upper and lower sides of the edge band, simplifying the structure of the edge banding machine while reducing the manufacturing cost and improving the processing efficiency of the plate.

[0083] like Figure 5 , 6 As shown, in some preferred embodiments, a second fine-tuning spring 218 is pressed against the lower end of the lower fine-tuning assembly 210b and the fine-tuning bracket 201. Thus, the elasticity of the second fine-tuning spring is used to drive the lower fine-tuning assembly to move up and down relative to the fine-tuning bracket to adapt to the adjustment error of the second positioning member, so that the second positioning member always presses against the bottom surface of the plate. Specifically, the two ends of the second fine-tuning spring are pressed against the slide seat and the fine-tuning bracket respectively.

[0084] like Figure 4 , 6As shown, in some preferred embodiments, the upper finishing assembly 210a is provided with a connecting rod 219 for connecting with the upper crossbeam, and the upper finishing assembly 210a is also provided with a mounting member 2191, the connecting rod 219 passes through the mounting member 2191, and one end is connected to the upper crossbeam, and the connecting rod 219 is respectively pressed against the third fine-tuning spring 2192 on both sides of the mounting member 2191. Thus, the elastic performance of the second fine-tuning spring is utilized to drive the upper finishing assembly to move up and down relative to the finishing bracket to adapt to the adjustment error of the second positioning member, so that the second positioning member is always pressed against the top surface of the plate. Specifically, the mounting member 2191 is connected to the slide seat 216.

[0085] After edge banding, some boards will also be rounded, that is, the two corners of the long sides on both sides of the edge band will be rounded to avoid scratches caused by too sharp corners, and to improve the aesthetics of the board to enhance market competitiveness. Figures 7-9 As shown, in some preferred embodiments, the edge banding machine also includes a chamfering device 300, which includes an upper chamfering assembly 301 and a lower chamfering assembly 302, wherein the upper chamfering assembly 301 is used to chamfer at least one end corner of the upper long side of the edge band, and the lower chamfering assembly 302 is used to chamfer at least one end corner of the lower long side of the edge band.

[0086] The upper chamfering assembly 301 includes a first chamfering mechanism 310a, which is connected to a first tracking component 320. The first tracking component 320 is used to drive the first chamfering mechanism 310a to track the plate 601 to move forward synchronously and to chamfer the plate 601 upward (downward) relative to the plate 601.

[0087] The above-mentioned lower chamfering assembly 302 includes: a second chamfering mechanism 310b, which is connected to a second tracking component 330. The second tracking component 330 is used to drive the second chamfering mechanism 310b to track the plate 601 and move forward synchronously when the chamfering process is performed, and drive the second chamfering mechanism 310b to move up (down) relative to the plate 601 to avoid the plate 601 after the chamfering process is completed.

[0088] The first chamfering mechanism 310a and the second chamfering mechanism 310b both include a chamfering tool 311 and a feed assembly, which is connected to the chamfering tool 311 to drive the chamfering tool 311 to feed into the plate for chamfering. Specifically, the chamfering tool 311 is connected to a chamfering motor 3110 for driving, and the chamfering motor 3110 is connected to the feed assembly.

[0089] Specifically, the first tracking assembly 320 is connected to the frame 600 through the upper chamfering bracket 303, and the second tracking assembly 330 is connected to the frame 600 through the lower chamfering bracket 304. During operation, the plate 601 is transported to the chamfering device 300, the first tracking assembly 320 (the second tracking assembly 330) drives the first chamfering mechanism 310a (the second chamfering mechanism 310b) to track the plate 601 and move forward synchronously, and the feed assembly drives the chamfering tool 311 to feed the plate 601 to perform chamfering; after the chamfering is completed, the first tracking assembly 320 (the second tracking assembly 330) continues to drive the first chamfering mechanism 310a (the second chamfering mechanism 310b) to move upward (downward) to avoid the plate 601.

[0090] like Figure 8 As shown, in some preferred embodiments, the first chamfering mechanism 310a and the second chamfering mechanism 310b both further include a support plate 313 and a positioning member 314; the support plate 313 is fixedly connected to the feed assembly relative to the chamfering tool 311, and is arranged on the side of the chamfering tool 311 close to the plate 601, and is used to abut against the front (rear) side of the plate 601, thereby providing a reference for the first tracking assembly 320 (second tracking assembly 330) to drive the first chamfering mechanism 310a (second chamfering mechanism 310b) to track the plate 601 to move forward synchronously; the positioning member 314 is arranged adjacent to the chamfering tool 311 in the vertical direction, and is used to position the side of the plate 601, thereby providing a position reference for the feed assembly to drive the chamfering tool 311 to feed the plate 601; the support plate 313 and the positioning member 314 position the plate 601 in the two-dimensional direction of the horizontal plane, and provide a working reference for the chamfering tool 311 to perform rounding processing. In this way, the accuracy of rounding is improved and the quality of the plate is stabilized.

[0091] Specifically, the feed assembly includes a chamfering feed guide rail, a chamfering feed slider and a chamfering feed drive. The extension direction of the chamfering feed guide rail is perpendicular to the conveying direction L of the plate in the horizontal plane and is connected to the first tracking assembly 320 / the second tracking assembly 330. The chamfering motor 3110 driving the chamfering tool 311 to rotate is connected to the chamfering feed slider through the first mounting seat 315, and the support plate 313 and the positioning member 314 are connected to the first mounting seat 315. The chamfering feed drive is connected to the first mounting seat 315 / the chamfering feed slider and is fixed relative to the chamfering feed guide rail, and is used to drive the chamfering tool 311 to feed toward the plate 601. Specifically, the chamfering feed drive can be a chamfering feed cylinder, the cylinder body of which is fixed relative to the chamfering feed guide rail, and its telescopic end is fixedly connected to the first mounting seat 315 / the chamfering feed slider, and the movement direction of its telescopic end is parallel to the extension direction of the chamfering feed guide rail. In some embodiments, the positioning member 314 is provided in an annular shape, and the chamfering tool 311 works by passing through the inner ring of the annular positioning member 314. Therefore, whether the chamfering tool is used to process the front end angle of the edge band or the rear end angle of the edge band, the annular positioning member can meet the positioning work of both usage situations, without the need to install multiple positioning members on the front and rear sides of the tool, or to disassemble and adjust a set positioning member, which is convenient and trouble-free to operate.

[0092] like Figure 7 , 8 As shown, in some preferred embodiments, the first chamfering mechanism 310a and the second chamfering mechanism 310b both further include an adjustment component, which is disposed between the first mounting seat 315 and the chamfering feed slider, and is used to drive the structure of the chamfering tool 311, the positioning member 314, and the support plate 313 to move forward and backward along the feed direction E according to specific usage conditions, so as to adjust the working position of the chamfering tool 311 and enable the positioning member 314 to press against the plate during operation. For example, the plate may slightly shift in the feed direction of the chamfering tool during transportation, and the movement of the adjustment component can adapt to the error in the working position between the plate and the chamfering tool caused by the slight position.

[0093] Specifically, the adjustment assembly includes an adjustment cylinder and an adjustment guide rail 3162, the first mounting seat 315 is connected to the adjustment guide rail 3162 through an adjustment slider 3163, the adjustment guide rail 3162 is connected to the chamfering feed slider through an adjustment mounting plate 3164, the cylinder body of the adjustment cylinder is fixedly connected to the adjustment mounting plate 3164, and its telescopic end is connected to the adjustment slider 3163 to drive the adjustment slider 3163 to move. More specifically, the first mounting seat 315 has a vertical side panel, and the adjustment assembly is arranged on the side of the first mounting seat and connected to the vertical side panel.

[0094] In some embodiments, the second tracking assembly 330 includes a linear tracking rail 331, a tracking slide 332, and a second tracking cylinder 333. The linear tracking rail 331 is tilted upward (downward) relative to the conveying direction L of the plate. The second tracking cylinder 333 is fixed relative to the linear tracking rail 331, and its telescopic end is connected to the tracking slide 332. The second chamfering mechanism 310b is connected to the tracking slide 332. Therefore, according to the principle of synthesis and decomposition of motion, the front-back motion and up-and-down motion of the second chamfering mechanism are driven by the tilted linear tracking rail. Through the ingenious structure, the structure of the chamfering device and the edge banding machine is greatly simplified, and the manufacturing cost is reduced. Specifically, the linear tracking rail 331 and the second tracking cylinder 333 are connected to the lower chamfering bracket 304, and the chamfering feed rail and the chamfering feed cylinder are connected to the tracking slide 332.

[0095] like Figure 7 As shown, in some preferred embodiments, the lower end of the linear tracking rail 331 is provided with an elastic buffer 334, which is used to provide buffering when the tracking slide 332 slides downward to the tail end to avoid collision and damage to the device. Specifically, the elastic buffer 334 can be a spring.

[0096] like Figure 7 , 9 As shown, in some embodiments, the first tracking assembly 320 includes a first tracking cylinder 3201 and a tracking swing arm 3202, one end of the tracking swing arm 3202 is relatively hinged to the upper chamfer bracket 303, the cylinder body of the first tracking cylinder 3201 is relatively hinged to the upper chamfer bracket 303, and the telescopic end of the first tracking cylinder 3201 is hinged to the tracking swing arm 3202, thereby, the upper chamfer bracket 303, the first tracking cylinder 3201 and the tracking swing arm 3202 form a connecting rod structure, and the tracking swing arm 3202 is driven to swing by the telescopic movement of the first tracking cylinder 3201. According to the principle of motion synthesis and decomposition, the first chamfering mechanism 310a is driven to move forward and backward and up and down through the swinging tracking swing arm 3202, and the structure of the chamfering device and the edge banding machine is greatly simplified through the ingenious structure, and the manufacturing cost is reduced. In some more preferred embodiments, the tracking swing arms 3202 are provided with two, the two tracking swing arms 3202 are arranged in parallel, one end is hinged to the upper chamfering bracket 303, and the other end is connected by hingedly connecting a swinging connecting plate 3203, and the first chamfering mechanism 310a is connected to the swinging connecting plate 3203, thereby ensuring that during the swinging process, the setting direction of each structure of the first chamfering mechanism remains unchanged, does not affect the operation of the first chamfering mechanism, and improves the stability of the swing. Specifically, the chamfering feed guide rail and the chamfering feed cylinder of the first chamfering mechanism are connected to the swinging connecting plate.

[0097] In specific operation, when the upper chamfering assembly 301 rounds the front end corner of the upper long side of the edge band, the first tracking cylinder 3201 is controlled to contract, and the tracking swing arm 3202 is tilted and relatively close to the vertical extension setting, so that the support plate 313 can block the plate 601 and contact the plate 601 (see Fig. 9 ); When the plate 601 is conveyed to the upper chamfering assembly 301, the front side surface of the plate 601 contacts the backing plate 313, and then pushes the backing plate 313 and the first chamfering mechanism 310a to move forward synchronously. At this time, the first tracking cylinder 3201 extends, and the chamfering feed drive drives the chamfering tool 311 to feed; due to the characteristics of the tracking swing arm 3202 driving the first chamfering mechanism 310a to move, while the first chamfering mechanism 310a moves forward, it moves upward synchronously, and the chamfering tool 311 moves to the front end corner position of the upper long side of the edge band under the combined movement of upward movement and feed movement to work, thereby completing the chamfering process of the front end corner. After the chamfering process is completed, the first chamfering mechanism 310a continues to move upward until the support plate 313 is separated from the plate 601, thereby allowing the first chamfering mechanism 310a to avoid the plate 601, and the plate 601 continues to be conveyed forward. When the plate 601 has completely passed through the first chamfering mechanism 310a, the first chamfering mechanism 310a moves in the opposite direction and resets to prepare for the next round of chamfering process.

[0098] When the upper chamfering assembly 301 is chamfering the rear end corner of the upper long side of the edge band, the first tracking cylinder 3201 is controlled to contract, and the tracking swing arm 3202 is tilted and relatively nearly horizontally extended, so that the lowest end of the support plate 313 is located above the plate 601 without affecting the plate 601 entering the upper chamfering assembly 301; when the plate 601 is conveyed to the upper chamfering assembly 301, the first tracking cylinder 3201 extends to drive the first chamfering mechanism 310a to catch up with the plate 601, and the support plate 313 contacts the rear side of the plate 601, and then pushes the plate 601 to move forward synchronously (see Fig. 9 ), and at the same time, the chamfering feed drive member drives the chamfering tool 311 to feed; due to the characteristics of the tracking swing arm 3202 driving the first chamfering mechanism 310a to move, the forward movement and downward movement of the first chamfering mechanism 310a are performed synchronously, and the chamfering tool 311 moves to the rear end corner position of the upper long side of the edge band under the combined movement of downward movement and feed movement to work, thereby completing the chamfering of the rear end corner. After the chamfering process is completed, the plate 601 continues to be transported forward, and the first chamfering mechanism 310a is remotely reset in the reverse direction to prepare for the next round of chamfering process.

[0099] When the lower chamfering assembly 302 rounds the front end corner of the lower long side of the edge band, the linear tracking guide rail 331 is tilted downward along the conveying direction L of the plate, and the second tracking cylinder 333 is controlled to extend, so that the support plate 313 can block the plate 601 and contact the plate 601; when the plate 601 is conveyed to the lower chamfering assembly 302, the front side of the plate 601 contacts the support plate 313, and then pushes the support plate 313 and the second chamfering mechanism 310b to move forward synchronously (see Fig. 9 ), and at the same time, the chamfering feed drive member drives the chamfering tool 311 to feed. Due to the characteristic that the linear tracking guide rail 331 drives the second chamfering mechanism 310b to move, the forward movement and downward movement of the second chamfering mechanism 310b are performed synchronously. Under the combined movement of downward movement and feed movement, the chamfering tool 311 moves to the front end corner position of the lower long side of the edge band to work, thereby completing the chamfering of the front end corner. After the chamfering is completed, the second chamfering mechanism 310b continues to move downward until the support plate 313 is separated from the plate 601, thereby allowing the second chamfering mechanism 310b to avoid the plate 601, and the plate 601 continues to be transported forward. When the plate 601 completely passes through the second chamfering mechanism 310b, the second chamfering mechanism 310b moves in the opposite direction to reset, preparing for the next round of chamfering.

[0100] When the lower chamfering assembly 302 rounds the rear end corner of the lower long side of the edge band, the linear tracking guide 331 is tilted upward along the conveying direction L of the plate, and the second tracking cylinder 333 is controlled to contract, so that the highest end of the support plate 313 is located below the plate 601 without affecting the plate 601 entering the lower chamfering assembly 302 (see Fig. 9 ); When the plate 601 is conveyed to the lower chamfering assembly 302, the second tracking cylinder 333 extends to drive the second chamfering mechanism 310b to catch up with the plate 601, and the support plate 313 contacts the rear side of the plate 601, and then pushes the plate 601 to move forward synchronously, and at the same time, the chamfering feed drive drives the chamfering tool 311 to feed; due to the characteristics of the linear tracking guide 331 driving the movement of the second chamfering mechanism 310b, the forward movement and upward movement of the second chamfering mechanism 310b are carried out synchronously, and the chamfering tool 311 moves to the rear end corner position of the lower long side of the edge band under the combined movement of the upward movement and the feed movement to work, thereby completing the chamfering of the rear end corner. After the chamfering process is completed, the plate 601 continues to be conveyed forward, and the second chamfering mechanism 310b is remotely reset in the reverse direction to prepare for the next round of chamfering.

[0101] Specifically, the action time and specific work of the first tracking cylinder 3201, the second tracking cylinder 333 and the chamfering feed drive relative to the plate conveying can be controlled by the PLC system. Further, the first tracking cylinder 3201 is connected to the upper chamfering bracket 303 through the second mounting seat 3204. Specifically, one end of the second mounting seat 3204 is fixedly connected to the upper chamfering bracket 303, and the other end is hinged to the cylinder body of the first tracking cylinder 3201. The fixed connection method can be threaded connection, so that according to the specific use of the upper chamfering mechanism and the specific work of the first tracking cylinder, the relative position of the second mounting seat and the upper chamfering bracket can be adjusted, thereby adjusting the relative position of the first tracking cylinder and the upper chamfering bracket.

[0102] In some embodiments, an infrared detection structure (not shown) is respectively disposed adjacent to the upper chamfering assembly 301 and the lower chamfering assembly 302. The infrared detection mechanism is connected to a PLC system for receiving information on sheet material transportation and transmitting it to the PLC system, which controls the operation of corresponding cylinders or motors.

[0103] like Figure 7 , 9 As shown, in some embodiments, the chamfering device 300 includes a front chamfering assembly 305 and a rear chamfering assembly 306. The front chamfering assembly 305 includes the upper chamfering assembly 301 and the lower chamfering assembly 302, which are used to chamfer the front end corners of the upper and lower long sides of the edge band; the rear chamfering assembly 306 includes the upper chamfering assembly 301 and the lower chamfering assembly 306, which are used to chamfer the rear end corners of the upper and lower long sides of the edge band. Specifically, the plate passes through the upper chamfering assembly of the front chamfering assembly, the lower chamfering assembly of the front chamfering assembly, the upper chamfering assembly of the rear chamfering assembly, and the lower chamfering assembly of the rear chamfering assembly in sequence, thereby completing the chamfering of the four end corners of the edge band in succession and continuously along the conveyance of the plate.

[0104] When the above-mentioned finishing device chamfers the upper and lower long edges of the edge banding, the finishing cutter mostly uses a milling cutter with multiple discontinuous V-shaped blades. There will be breakpoints in the milling of the milling cutter. In some cases, since the position of the milling cutter is relatively fixed, if the plate vibrates or shifts slightly during the transportation process, it is easy to cause the milling cutter to fail to continuously act on the plate edge banding. Then, there will be processing breakpoints in the plate edge banding, making the rounded surfaces of the upper and lower long edges of the edge banding uneven, seriously affecting the product quality and its appearance.

[0105] like Figures 10-11As shown, in some preferred embodiments, the edge banding machine further includes a scraping device 400, which includes: a scraping unit for scraping the R angle at the edge corner of the plate; a limiting unit for being close to the plate when the plate is scraped to limit the plate, the limiting unit includes a main limiting body 410 arranged on one side of the plate and a secondary limiting body 420 arranged on the top and / or bottom side of the plate, the main limiting body 410 and the secondary limiting body 420 are both rolling bodies; a first elastic unit 44030 for providing elastic pressure in the horizontal direction to the main limiting body 410; and a second elastic unit 40 for providing elastic pressure in the vertical direction to the secondary limiting body 420. Thus, the rounded corners of the long sides of the upper and lower sides of the edge band are scraped by the scraping device to make the rounded corners smooth, thereby overcoming the quality problem caused by the uneven surface of the rounded corners left over from the fine finishing.

[0106] Specifically, the scraping device 400 is connected to the above-mentioned frame 600 through a scraping bracket 401; the scraping unit includes a scraping mounting seat 451 and a scraper 452 with a V-shaped blade (with a blade seat, not marked in the figure), and a movable seat 453 is installed on the scraping mounting seat 451, and the scraping mounting seat 451 is installed on the scraping bracket 401 through the second elastic unit 430, and the movable seat 453 is installed on the scraping mounting seat 451 through the first elastic unit 440; the scraper 452, the main limiting body 410 and the auxiliary limiting body 420 are all connected to the movable seat 453. Specifically, the scraping edge mounting seat 451 is provided with a first guide hole (not marked in the figure), and a plurality of first guide rails 454 are installed on the scraping edge bracket 401, and the first guide rails 454 are perpendicular to the horizontal ground. One end of the first guide rail 454 is connected to the scraping edge bracket 401, so that the first guide rail 454 passes through the first guide hole on the scraping edge mounting seat 451, and the top or bottom of the scraping edge mounting seat 451 is installed on the scraping edge bracket 401 through the second elastic unit 430. The scraping edge mounting seat 451 is provided with a second guide hole (not marked in the figure) and a second guide rail 455, and the second guide rail 455 is parallel to the horizontal ground. The movable seat 453 is provided with a third guide hole (not marked in the figure), and the second guide rail 455 passes through the second guide hole and the third guide hole respectively, so as to connect the scraping edge mounting seat 451 and the movable seat 453.

[0107] During specific operation, the second elastic unit 430 is used to provide the auxiliary limiting body 420 with a pressing force on the upper and / or lower sides of the plate, and the first elastic unit 440 provides the main limiting body 410 with a lateral horizontal pressing pressure on the plate. When the plate is horizontally transported to the scraping unit for processing the R angle, the auxiliary limiting body 420 presses the plate surface upward and / or downward, and the main limiting body 410 presses against the plate from one side of the plate to limit the plate. Through the elastic characteristics of the first elastic unit and the second elastic unit, the adjustment error of the main limiting body and the auxiliary limiting body, as well as the error caused by the non-linear conveying of the plate, can be adapted to the scraper 452 unit to always follow the movement trajectory of the plate to perform scraping operations on the plate. In a preferred embodiment, the first elastic unit 440 and the second elastic unit 430 are both spring structures. The purpose of the main limiting body 410 and the auxiliary limiting body 420 being rolling bodies is that the main limiting body 410 and the auxiliary limiting body 420 roll relative to the plate surface while pressing against the plate surface to prevent the plate surface from being worn. Specifically, the main limiting body 410 and the auxiliary limiting body 420 can be rollers or disc-shaped, wherein, when the main limiting body 410 is disc-shaped, its surface close to the side of the plate is the vertical surface, and the rolling body can be connected by a connecting shaft and a bearing structure, which is a prior art and will not be described in detail here. It is worth adding that in the above embodiment, only the upper long side or the lower long side of the edge band can be processed, that is, in the above embodiment, only the side of the edge band can be processed from the top, or only the side of the edge band can be processed from the bottom. In some embodiments, two identical groups of the above-mentioned structures are arranged on the scraping bracket 401, and the two groups of structures are installed in reverse order, so that the upper and lower long edges of the edge banding strip can be scraped during the horizontal conveying of the plate. The first group of mechanisms can first process the upper long edge of the edge banding strip, and the top of the scraping mounting seat 451 is installed on the top of the scraping bracket 401 or directly connected to the upper crossbeam through the second elastic unit 430; then the second group of mechanisms processes the lower long edge of the edge banding strip, and the bottom of the scraping mounting seat 451 is installed on the bottom of the scraping bracket 401 through the second elastic unit 430.

[0108] When the top of the scraping edge mounting seat 451 is connected to the upper crossbeam through the second elastic unit 430, a connecting arm 431 is extended from the top of the scraping edge mounting seat 451 and the upper crossbeam in the horizontal direction, and the top of the scraping edge mounting seat 451 and the connecting arm of the upper crossbeam are connected by a connecting screw 432, which is perpendicular to the horizontal ground, and a spring (second elastic unit 430) is sleeved on the connecting screw 432, and the two ends of the spring are respectively abutted on the surfaces of the two connecting arms. Further, the other end of the connecting screw 432 is protrudingly arranged below the connecting arm 431, and a limiting convex portion 433 is connected thereto, and an auxiliary spring 434 is also sleeved on the connecting screw 432, and the two ends of the auxiliary spring 434 are respectively abutted on the bottom of the connecting arm 431 and the limiting convex portion 433, and its purpose is: when the plate lifts up the rolling body located on its upper side, the auxiliary spring 434 plays a role of booster, exerting an upward force on the scraping edge mounting seat 451.

[0109] In order to make the scraper 452 withdraw from the processing position after the plate is processed, in the present embodiment, a first transmission structure 460 is installed on the scraping mounting seat 451, and the first transmission structure 460 is used to drive the movable seat 453 to move horizontally. Preferably, the first transmission structure 460 is a cylinder. In practical applications, the cylinder is mounted on one end of the second guide rail 455 through a base 461. A first bolt 441 and a first fixed block 442 are connected to the scraping mounting seat 451. The first bolt 441 is parallel to the horizontal ground. One end of the first bolt 441 is fixedly connected to the scraping mounting seat 451, and the other end of the first bolt 441 passes through the base 461 and is connected to a limit nut 443. A spring (first elastic unit 440) is sleeved on the first bolt 441 (such as Fig.10 As shown in FIG. 4 ), one end of the spring abuts against the base 461, and the other end of the spring abuts against the limit nut 443, and the telescopic end of the cylinder is connected to the first fixed block 442. During operation, the telescopic end of the cylinder extends in the direction E. Since the scraping edge mounting seat 451 is fixed in position, the cylinder moves the second guide rail 455 and the movable seat 453 in the opposite direction of the direction E to achieve the knife retraction effect. At the same time, the base 461 moves in the opposite direction of the direction E to squeeze the spring; when the cylinder deflates and the telescopic end retracts, the movable seat 453 moves in the direction E, and the base 461 relaxes the pressure on the spring. At this time, the elastic pressure of the main limit body 410 on the movable seat 453 on the plate is provided by the spring on the first bolt 441.

[0110] Since different types of plates use edge bands of different thicknesses, the plates have different width specifications. In order to make the main limiter 410 suitable for plates of various specifications, it is necessary to horizontally adjust the main limiter 410 away from or close to the conveying trough. In order to achieve automatic adjustment, in some preferred embodiments, an adjustment slider 471 and a second transmission structure are installed on the movable seat 453. The main limiter 410 is connected to the adjustment slider 471 (the adjustment slider 471 is connected to the slide rail on the movable seat 453, and the slide rail is not drawn in the figure). The second transmission structure is used to drive the adjustment slider 471 to move horizontally. Preferably, the second transmission structure includes a transmission screw 473 and a servo motor 472. The servo motor 472 is installed on the movable seat 453 through a motor seat. One end of the transmission screw 473 is threadedly connected to the adjustment slider 471, and the other end of the transmission screw 473 is connected to the motor shaft of the servo motor 472 (can be connected through a coupling). The limiting bracket 4101 for installing the main limiting body 410 is connected to the adjusting slider 471 .

[0111] In this embodiment, the third transmission structure is installed on the movable seat 453, which is used to drive the auxiliary limiting body 420 to move in the vertical direction for position adjustment, so as to perform limit adjustment according to plates of different thicknesses. Specifically, the third transmission structure includes a second bolt 481, a spring column, a pressure block 483 and a connecting seat 484, the pressure block 483 and the spring column are both installed in the connecting seat 484, the limiting bracket 4101 used to connect the auxiliary limiting body 420 extends into the connecting seat 484 and is connected to the pressure block 483, the surface of the connecting seat 484 is provided with a through groove 4841, the through groove 4841 runs through the surface of the connecting seat 484, so as to allow the limiting bracket 4101 to move up and down, the top of the connecting seat 484 is provided with a screw hole, the second bolt 481 is threadedly connected to the screw hole, one end of the second bolt 481 extends vertically downward from the top of the connecting seat 484 into the connecting seat 484 and presses on the top of the pressure block 483, and the spring column presses on the bottom of the pressure block 483. When in use, the second bolt 481 is screwed for adjustment, so that one end of the second bolt 481 moves toward the pressing block 483 to press and drive the secondary limiting body 420 to move, or one end of the second bolt 481 moves away from the pressing block 483 to release the pressure on the pressing block 483, so that the spring column presses the pressing block 483 and drives the secondary limiting body 420 to move. In order to facilitate the rotation of the second bolt 481, a hand wheel 485 is installed at the other end of the second bolt 481.

[0112] The edge banding is pressed tightly against the side of the board by the pressing mechanism. During the pressing process, the unsolidified colloid will be squeezed out to the top or bottom surface of the board (or the colloid will overflow from both the top and bottom surfaces). After the colloid dries, it will seriously affect the appearance of the board and the product quality.

[0113] like Figures 12-13As shown, in some preferred embodiments, the edge banding machine further includes a glue scraping device 500, which includes: a glue scraping assembly 510, used to scrape glue on the plate; a limiting assembly 520, used to press and limit the plate when the plate is scraped with glue, and the limiting assembly 520 includes an upper limit plate 521 arranged above the plate and a lower limit plate 522 arranged below the plate. Thus, the upper limit plate and the lower limit plate are used to press against the top and bottom surfaces of the plate, and the glue on the top and / or bottom surfaces of the plate is scraped off by scraping glue, so as to avoid affecting the appearance and product quality of the plate.

[0114] In some preferred embodiments, the scraping device 500 further includes an elastic clamping component 530, which is connected to the limiter component 520 to provide an elastic clamping force to the upper limit plate 521 and / or the lower limiter plate 522. Therefore, the use of an elastic clamping component to provide a clamping force to the upper limit plate and / or the lower limiter plate to clamp the plate can effectively keep the structure of the scraping device unchanged when it works for a long time, and the clamping force of the elastic clamping component on the plate remains unchanged, thereby improving the stability of the plate when passing through the scraping mechanism, and ensuring the scraping efficiency and product quality; for example, when a cylinder is used to provide a clamping force for the clamping component, the cylinder will have unstable air pressure when working for a long time, so that the upper limit plate and the lower limiter plate cannot keep the plate pressed, which will cause the plate to vibrate slightly when passing through the scraping mechanism, so that the edge band material is easily scratched and deformed by the scraper, and even the surface of the plate may be damaged.

[0115] Specifically, the above-mentioned limiting assembly 520 includes a first limiting assembly 520a, the above-mentioned scraper assembly 510 includes a first scraper assembly 510a, and the above-mentioned elastic clamping assembly 530 includes a first elastic clamping assembly 530a; the first scraper assembly 510a is connected to the first limiting assembly 520a, and the first elastic clamping assembly 530a is connected to the first limiting assembly 520a; the above-mentioned upper limit plate 521 and the lower limit plate 522 are arranged relatively to each other up and down, the first limiting assembly 520a is connected to the upper limit plate 521 or the lower limit plate 522, and the first limiting assembly 520a is connected to the above-mentioned frame 600 through the scraper fixing plate 540. When the first limit assembly 520a is connected to the upper limit plate 521, the first glue scraping assembly 510a performs glue scraping on the top surface of the plate, and the lower limit plate 522 can be directly connected to the frame 600; when the first limit assembly 520a is connected to the lower limit plate 522, the first glue scraping assembly 510a performs glue scraping on the bottom surface of the plate, and the upper limit plate 521 can be directly connected to the frame 600. When the plate is transported to between the upper limit plate 521 and the lower limit plate 522 through the conveying trough, the first glue scraping assembly 510a scrapes glue on the surface of the plate. It is worth noting that the first limit assembly can be connected to the upper limit plate or the lower limit plate, and then in actual application, two glue scraping stations can be set on the edge banding machine along the extension direction of the conveying trough, that is, two sets of glue scraping devices are set to continuously scrape glue on the top and bottom surfaces of the plate, and the two sets of glue scraping devices are symmetrical and staggered.

[0116] Further, in order to realize the simultaneous scraping of the top and bottom surfaces of the plate at the same scraping station, in some preferred embodiments, the above-mentioned limit assembly 520 further includes a second limit assembly 520b, the above-mentioned scraping assembly 510 further includes a second scraping assembly 510b, and the above-mentioned elastic pressing assembly 530 further includes a second elastic pressing assembly 530b; the second scraping assembly 510b is connected to the second limit assembly 520b, and the second elastic pressing assembly 530b is connected to the second limit assembly 520b; the second limit assembly 520b is connected to the upper limit plate 521 or the lower limit plate 522, and the second limit assembly 520b is connected to the above-mentioned frame 600 through the scraping fixing plate 540. Specifically, when the first limit assembly 520a is connected to the upper limit plate 521 (lower limit plate 522), the second limit assembly 520b is connected to the lower limit plate 522 (upper limit plate 521). Thus, the same scraping station can scrape glue on the top and bottom surfaces of the plate at the same time, simplifying the structure of the edge banding machine, reducing manufacturing costs, and improving the processing efficiency of the plate to a certain extent. Specifically in this embodiment, the first scraping assembly is connected to the upper limit plate, and the second scraping assembly is connected to the lower limit plate.

[0117] In some embodiments, the first limiting assembly 520a and the second limiting assembly 520b each include a fixed mounting seat 523, a sliding mounting seat 524, a limiting connecting plate 525 and a vertical guide rail 526, wherein the fixed mounting seat 523 is connected to the scraper fixing plate 524, the vertical guide rail 526 passes through the fixed mounting seat 523, one end of which is connected to the limiting connecting plate 525, and the other end of which is connected to the sliding mounting seat 524, the elastic clamping assembly 530 is fixedly connected relative to the fixed mounting seat 523 and presses the sliding mounting seat 524, the scraper assembly 510 and the upper limit plate 521 (or the lower limit plate 522) are connected to the sliding mounting seat 524, thereby, the elastic clamping assembly 530 provides elastic pressure to make the sliding mounting seat 524 move closer to the plate, driving the upper limit plate 521 (or the lower limit plate 522) to move against the plate so that the upper limit plate 521 (or the lower limit plate 522) presses the plate.

[0118] In some embodiments, the first elastic clamping assembly 530a and the second elastic clamping assembly 530b both include a clamping screw 531 and a clamping spring 532. The clamping screw 531 is perpendicular to the horizontal ground, one end of which is installed on the fixed mounting seat 523, and the other end of which passes through the limiting connecting plate 525 and is sleeved with the above-mentioned clamping spring 532. One end of the clamping spring 532 abuts against the limiting connecting plate 525, and a clamping nut 533 is installed on the clamping screw 532, and the other end of the compression spring 532 abuts against the clamping nut 523. During specific use, since the horizontal height position of the fixed mounting seat 523 is relatively fixed, when the plate 601 passes between the upper limit plate 521 and the lower limit plate 522, the two limit plates will be lifted up, and the other end of the clamping spring 532 is limited by the clamping nut 523 and the position is fixed, a directional force will be applied to the two limit plates, and the force transmission direction is: the compression spring 532, the limit connecting plate 525, the vertical guide rail 526, the sliding mounting seat 524 and the upper limit plate 521 (or the lower limit plate 522) on the sliding mounting seat 524, so that the two limit plates are pressed downward (upward) by the compression spring to press against the plate 601.

[0119] Specifically, the first scraper assembly 510a and the second scraper assembly 510b each include a scraper 511 , and the scraper 511 is connected to the first limit assembly 520a or the second limit assembly 520b via a handle 512 . Specifically, the handle 512 is connected to the fixed sliding mounting seat 524 .

[0120] In actual application, the upper limit plate 521 (lower limit plate 522) is set on one side of the scraper 511. It is worth noting that the bottom of the upper limit plate 521 (the top of the lower limit plate 522) should be flush with the tip of the scraper 512. The two ends of the bottom edge of the upper limit plate 521 are inclined upward, and the two ends of the top edge of the lower limit plate 522 are inclined downward, so as to form a trumpet shape to guide the plate 601 into the gap between the two limit plates. Furthermore, in order to reduce the phenomenon of the plate surface being scratched by the scraper, the contact area between the tip of the scraper and the surface of the plate can be reduced. Therefore, the tip of the scraper can be slightly tilted, but it should be ensured that the tip of the scraper can scrape off the colloid on the surface of the plate. In actual use, the plate is transported horizontally, and the plate passes through the gap between the upper limit plate 521 and the lower limit plate 522, so that the scraper 511 scrapes off the colloid protruding from the surface of the plate.

[0121] In actual use, due to the different specifications of the plate materials, if the scraper position is not changed, the scraping work cannot be performed, and the structural functionality is greatly limited. In some preferred embodiments, the scraper device also includes a horizontal adjustment component 550, and the first limit component 520a and / or the second limit component 520b are connected to the scraper fixing plate 540 through the horizontal adjustment component 550. The horizontal adjustment component 550 is used to drive the first limit component 520a or the second limit component 520b to move in the horizontal direction for position adjustment, thereby adjusting the position of the scraper 511, for example, adjusting the scraper 511 forward along the direction E or adjusting the scraper 511 backward in the direction E.

[0122] Specifically, the horizontal adjustment structure 550 includes a horizontal guide rail 551 and an adjustment screw 552. One end of the horizontal guide rail 551 passes through the fixed mounting seat 523 and is connected to the scraper fixing plate 540, and is vertically installed on the scraper fixing plate 540. The other end of the horizontal guide rail 551 is installed with an adjustment connecting plate 554. One end of the adjustment screw 552 passes through the adjustment connecting plate 554 and is threadedly connected to the fixed mounting seat 523. The adjustment screw 552 is parallel to the horizontal guide rail 551. When in use, the operator screws the other end of the adjustment screw 552. Under the action of the threaded connection transmission, the fixed mounting seat 523 moves horizontally on the horizontal guide rail 551, thereby driving the scraper assembly 510 to move horizontally.

[0123] In order to facilitate accurate adjustment of the moving distance of the scraper 511, in some embodiments, a counting device 553 is provided on the horizontal adjustment structure 550, and the counting device 553 is used to record the moving distance of the fixed mounting seat 523 in the horizontal direction. The counting device 553 is a counter (mechanical manual counter), and the adjusting screw 552 passes through the counter. When the operator turns the adjusting screw 552, the number of rotations or the rotation angle of the adjusting screw 552 is displayed on the number plate on the counter to calculate the horizontal moving distance of the above structure. The connection method between the counter and the adjusting screw is a prior art and will not be described in detail herein.

[0124] In actual use, when no plate passes by or when it is not necessary to scrape the plate, the scraper 511 can be retracted first, that is, the upper and lower scrapers are moved away from each other. In some preferred embodiments, a reset transmission structure 560 is provided between the fixed mounting seat 523 and the limit connecting plate 525 or the sliding mounting seat 524, and the reset transmission structure 560 is used to drive the scraper assembly 510 to move up and down, thereby being able to retract the scraper.

[0125] Specifically, the reset transmission structure 560 can be a scraper return cylinder, the cylinder body of which is fixedly connected to the limit connecting plate 525, and the telescopic end of the scraper return cylinder performs telescopic movement toward the fixed mounting seat 523. When in use, the telescopic end (not shown in the figure) of the scraper return cylinder extends toward the fixed mounting seat 523 and abuts against the fixed mounting seat 523, so that the limit connecting plate 525 is lifted up, driving the vertical guide rail 526 and the sliding mounting seat 524 to move away from the plate to achieve the retraction. Specifically, a force-bearing part (not shown in the figure) is provided at the position of the fixed mounting seat 523 corresponding to the telescopic end of the scraper return cylinder, and the force-bearing part is used to receive the telescopic end when the telescopic end is extended.

[0126] In order to further adjust the position of the scraper in the vertical direction, that is, the height relative to the surface of the plate, the tail of the handle 512 is provided with a connection part (not marked in the figure), the connection part is provided with an external thread (not drawn in the figure), and the sliding mounting seat 524 is provided with a threaded hole (not marked in the figure), the threaded hole passes through the surface of the sliding mounting seat 524 and is perpendicular to the horizontal ground, and the above connection part is threadedly connected with the threaded hole. The scraper 511 is installed at the head of the handle 512, and the connection part is screwed to adjust the height of the scraper 511 up and down.

[0127] In order to clean the waste glue on the surface of the plate while scraping the glue, the upper limit plate 521 and / or the lower limit plate 522 and / or the sliding mounting seat 524 are provided with a blowing port for connecting an external air pipe (not shown in the figure), an air pump (not shown in the figure) and other devices. The blowing port is used for blowing air to blow away the waste material on the surface of the plate.

[0128] Specifically, the edge banding machine also includes a PLC system and an electrical control system. The motor structure of the above-mentioned work is connected to the PLC system, the cylinder structure of the above-mentioned work is connected to the electrical control system, and the PLC system is connected to the electrical control system, and the work of the edge banding machine is generally controlled by the PLC control system. Specifically, the PLC system can be connected to a display screen and an input key component for communication between man and machine. The input key component can be in the form of a physical key, with an independent keyboard, or in the form of a touch key, with a touch display screen integrated with the display screen.
