Description

Technical Field

[0001] This utility model relates to the field of edge banding machine technology, and in particular to a visual adjustment structure for edge banding machines. Background Technology

[0002] Edge banding machines are key equipment in the wood furniture and board processing industry. Their core function is to band the edges of boards. Edge banding not only significantly improves the appearance quality of furniture, but also effectively prevents damage to the edges of boards during transportation and use, prevents the veneer from peeling or flaking off, and also has multiple functions such as waterproofing, sealing off the release of harmful gases inside the board, and reducing deformation of the board due to humidity changes.

[0003] Edge banding machines typically integrate multiple processes such as pre-milling, gluing, tape feeding, pressing, trimming, edge trimming, tracking, scraping, flexible flat scraping, and polishing. The precise coordination of these mechanisms is crucial for ensuring edge banding quality. Among these, the fine-tuning accuracy of key functional components such as the trimming, gluing, scraping, and polishing mechanisms directly affects the edge flatness, glue uniformity, and surface smoothness of the banded board. Currently, fine-tuning of these mechanisms largely relies on traditional adjusting shaft structures. The adjustment process primarily involves manually estimating the depth of the adjusting shaft's advance and retreat, requiring repeated fine-tuning of the limit device and trial-and-error to determine the optimal distance—a typical "blind adjustment" mode. This method has the following significant drawbacks: First, it lacks intuitive feedback on the adjustment amount, requiring operators to rely on experience to judge whether the adjustment is adequate, easily leading to over- or under-adjustment due to visual errors; second, the adjustment accuracy is low, the manual trial-and-error process is cumbersome and inefficient; third, the adjustment results are significantly affected by differences in operator experience, making it difficult to ensure consistency in adjustment between different machines or different batches of the same machine, thus affecting the stability of the edge banding quality of batch products. Utility Model Content

[0004] To overcome the problems existing in related technologies, this utility model provides a visual adjustment structure for edge banding machines. By cooperating with the annular scale mark and the indicator, the adjustment amount is visualized and fed back, which can accurately and efficiently adjust the axial displacement of the transmission component, reduce reliance on manual experience and ensure adjustment consistency.

[0005] This utility model provides a visual adjustment structure for an edge banding machine, including a pointing seat, a rotating ring, and a transmission component;

[0034] Preferred embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the scope of the present invention to those skilled in the art.

[0035] The technical solutions of the embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0036] like Figures 1 to 3 As shown, this utility model proposes a visual adjustment structure for an edge banding machine, including a pointing seat 1, a rotating ring 2, and a transmission component 3;

[0037] The pointer seat 1 has a first sidewall 11 and a second sidewall 12 disposed opposite to each other. The rotating ring 2 is rotatably disposed on the first sidewall 11. The rotating ring 2 is provided with an annular scale mark 20. The pointer seat 1 is provided with an indicator part 13 pointing to the annular scale mark 20. The rotating ring 2 is provided with a mating part 4. The transmission member 3 passes through the mating part 4 and is threadedly engaged with the pointer seat 1. One end of the transmission member 3 extends to the outside of the second sidewall 12 of the pointer seat 1.

[0038] Specifically, the guide seat 1 can be made of aluminum alloy or cast iron, and has a frame-type or block-shaped structure design. The guide seat 1 has a first sidewall 11 and a second sidewall 12 arranged relatively parallel to each other. The first sidewall 11 is the mounting side of the rotating ring 2. The guide seat 1 has a through shaft hole corresponding to the first sidewall 11 and the second sidewall 2. The shaft hole is used for the rotational support of the rotating ring 2. The shaft hole has an internal thread hole that is threaded with the transmission component 3, and the axis of the internal thread hole is collinear with the axis of the rotating ring 2 to ensure the coaxiality of the axial movement of the transmission component 3. The guide seat 1 can be bolted to the actuating component of the edge banding machine, such as the glue application mechanism 7, the tracking mechanism 8, the edge scraping mechanism, or the polishing mechanism 9.

[0039] The rotating ring 2 is an annular cylindrical structure, rotatably fitted into the shaft hole of the first sidewall 11 via a bearing or bushing (not shown in the figure). The outer circumferential surface of the rotating ring 2 is provided with annular scale markings 20. The scale unit of the annular scale markings 20 can be rotated according to actual needs; for example, it can be set to an angle value when adjusting the angle, and a distance value (mm) can be used when adjusting the displacement of the actuator. The annular scale markings 20 are formed by laser engraving, and the scale lines are filled with black ink. For example, when installed in the glue-applying mechanism 7, the lead of the transmission component can be set to a range of 1mm to 2mm. In this case, the outer circumference of the rotating ring 2 is evenly distributed with 5 large divisions, each large division having 5 small divisions. Each large division can display 0.1mm or 0.2mm, and each small division can display 0.02mm and 0.04mm. To clearly obtain the axial displacement of the transmission rod, the pointing seat 1 is provided with an indicator part 13, which can be a metal pointer or laser-engraved lines. To further enhance the digital feedback of adjustment accuracy, the adjustment structure can also be equipped with a grating encoder (not shown) and a display screen (not shown). The grating encoder is an incremental grating encoder, and the display screen can be an LCD or OLED digital display. The grating encoder is coaxially connected to the end of the rotating ring 2 via a flexible coupling. Its housing is fixed to the pointing seat 1 by a bracket. The detection shaft is rigidly connected to the rotation shaft of the rotating ring 2 for real-time acquisition of the rotation angle of the rotating ring 2. A dust cover is provided on the first side wall 11 of the pointing seat 1 corresponding to the position of the grating encoder. The dust cover can be made of ABS plastic and is connected to the first side wall 11 by screws. A sealing ring is provided inside the dust cover to achieve sealed isolation between the grating encoder and the external environment, preventing contaminants such as sawdust and glue mist from entering the encoder during the operation of the edge banding machine and affecting the detection accuracy. The display screen is electrically connected to the optical encoder via a shielded wire, which can be 1-2m in length. The display screen converts the rotation angle signal collected by the optical encoder into an axial adjustment amount and displays it in real time in digital form, achieving dual visual feedback of scale indication and digital display. This allows for adjustment and observation through the display screen in narrow positions, eliminating the need for operators to stick their heads into the confined space.

[0040] The rotating ring 2 has a mating part 4 embedded inside. The mating part 4 can be a steel sleeve, which is clearance-fitted with the inner wall of the rotating ring 2 and fixed to the rotating ring 2 by a locking member 5. The axial length of the mating part 4 is the same as or less than the length of the rotating ring 2. Its inner wall is clearance-fitted or threaded with the outer circumferential surface of the transmission component 3. When clearance-fitted, the clearance can be set to 0.01-0.05mm to ensure that the transmission component 3 can move axially and rotate synchronously with the mating part 4. The outer circumference of the rotating ring 2 can also be provided with strip-shaped anti-slip ridges evenly distributed along the circumference. The height of the strip-shaped anti-slip ridges can be 0.8-1.2mm, the width 2-3mm, and the spacing 5-8mm to increase the friction when the operator rotates the rotating ring 2 and prevent slippage.

[0041] The transmission component 3 is a stepped shaft structure, with a lead screw section as its main body. The lead screw section has an external thread on its outer circumference, which engages with the internal threaded hole of the guide seat 1 to form a lead screw and nut transmission pair. One end of the transmission component 3 passes through the inner hole of the mating part 4 and the internal threaded hole of the guide seat 1 in sequence, extending to the outside of the second side wall 12. The extended end of the transmission component 3 is used to connect to the actuating component of the edge banding machine. This extended end can also be equipped with a quick-release connection part for quick connection to the actuating component of the edge banding machine. This quick-release connection part includes an external threaded section on the outer circumference of the transmission component 3 and a locating pin hole that penetrates radially. The external threaded section engages with the internal threaded hole of the actuating component, and the locating pin hole is used to pass a locating pin to achieve circumferential positioning of the transmission component 3 and the actuating component. Furthermore, the other end of the transmission component 3 is also provided with a shoulder to limit the axial movement limit position. The lead of the transmission component 3 (i.e., the axial displacement of the transmission component 3 per revolution) is designed to be 0.5mm-10mm. The specific selection depends on the required adjustment precision. For example, the glue application mechanism 7 can use a lead of 0.5-2mm, the trimming mechanism can use a lead of 1-5mm, the scraping mechanism can use a lead of 1-4mm, and the polishing mechanism 9 can use a lead of 4-10mm. The thread precision of the lead screw section of the transmission component 3 can be 6H / 6g grade to ensure smooth transmission and adjustment precision.

[0042] The locking element 5 is used to achieve a rigid connection between the rotating ring 2, the mating part 4 and the transmission element 3. The locking element 5 can be a machined set screw. The side wall of the rotating ring 2 is provided with a groove. The groove is formed on the outer circumference of the rotating ring 2 by machining (such as milling or turning) and is in the form of a ring or a partially arc-shaped groove structure. The groove is used to place the machined set screw to ensure that when the rotating ring 2 rotates, the machined set screw can move synchronously circumferentially with the rotating ring 2, thereby driving the transmission element 3 to rotate.

[0043] A spring 6 is fitted around the outer periphery of the transmission component 3. The spring 6 is a cylindrical helical compression spring made of 65Mn, with a wire diameter of 0.5-3mm and a free length of 15-40mm. One end of the spring 6 abuts against the end face of the mating part 4 near the first side wall 11, and the other end abuts against the outer surface of the first side wall 11 of the pointing seat 1. The spring 6 is pre-compressed by 10%-50% during assembly. By continuously providing axial preload, the thread clearance of the lead screw and nut pair is eliminated, avoiding backlash error caused by clearance when the transmission component 3 moves axially, and improving the repeatability accuracy of adjustment. For example, the wire diameter of the spring 6 can be set to 0.7mm, the length to 33mm, and the pre-compression to 14mm.

[0044] To enhance safety, this embodiment also includes a buzzer, which is electrically connected to the signal processing module of the grating encoder via a wire. When the grating encoder detects that the theoretical axial displacement corresponding to the rotation angle of the rotating ring 2 deviates from the actual axial movement of the transmission component 3 by more than a threshold (e.g., ±0.05mm), it is determined that the transmission component 3 has abnormal axial movement (such as thread jamming, loose mating part 4, or other faults), and the buzzer triggers a continuous alarm to remind the operator to stop the machine for inspection.

[0045] Through the above technical solution, this utility model completely replaces the blind adjustment mode of the traditional edge banding machine by using a visual adjustment scheme of mechanical scale and digital coding, realizing intuitive feedback of the adjustment amount and solving the problems of low efficiency, poor accuracy and insufficient consistency of traditional adjustment. It is especially suitable for the high-precision fine adjustment needs of the glue application mechanism 7, tracking mechanism 8, edge scraping mechanism, polishing mechanism 9 and other mechanisms of the edge banding machine.

[0046] The present invention will be further illustrated below with specific embodiments.

[0047] In this utility model, the glue application mechanism 7 of the edge banding machine can be referenced in CN115365066B, and the tracking mechanism 8, the edge scraping mechanism and the polishing mechanism 9 can be referenced in CN119550449B.

[0048] Example 1

[0049] See Figure 4 , Figure 4 This is a schematic diagram of the existing glue application mechanism 7.

[0050] like Figure 4 As shown, in order to address the problem of insufficient adjustment accuracy of the glue gate 73 opening in the glue application mechanism 7 and its reliance on manual experience, the original adjustment components of the glue application mechanism 7, namely the adjustment nut and the limit screw, are replaced by the visual adjustment structure of this utility model. The precise visual adjustment of the glue gate 73 opening is achieved through mechanical scale and digital feedback.

[0051] like Figures 5 to 9As shown, the glue application mechanism 7 includes a melt box 71, a glue application shaft 72, a glue door 73, a connecting rod 74, and a cylinder 75. The cylinder 75 is mounted and fixed on the device body. The telescopic shaft of the cylinder 75 is hinged to the first end of the connecting rod 74. The connecting rod 74 has a hexagonal through hole in the middle. The glue door 73 is located inside the melt box 71. One end of the glue door 73 extends to the top end face of the melt box 71 and is inserted into the hexagonal through hole. When the cylinder 75 is started, the connecting rod 74 drives the glue door 73 to rotate, so as to ensure that the glue door 73 and the glue application shaft 72 are in the normally open state.

[0052] In this embodiment, the lead of the transmission component 3 can be set to 0.5–2 mm, for example, 1.75 mm. In this case, the middle part of the transmission rod is rigidly connected to the glue gate through a hexagonal through-hole, so the rotation center of the connecting rod is the central axis of the hexagonal through-hole. The stud abuts against one end of the connecting rod. When the stud moves axially, it pushes the connecting rod to rotate around the central axis, thereby causing the glue gate to move in an arc around this axis, changing the glue dispensing gap between the glue gate and the glue application shaft. That is, the connecting rod, the stud's point of action, and the glue gate's trajectory form a virtual triangle: the axial movement (linear displacement) of the stud is one right-angled side of the triangle, and the rotation radius of the connecting rod (the distance from the stud's point of action to the central axis) is the other right-angled side; the rotation arc length of the glue gate (corresponding to the change in glue dispensing gap) is proportional to the rotation angle. Therefore, the distance from the stud's point of action to the rotation center of the connecting rod is L1 (lever arm), and the distance from the edge of the glue gate to the rotation center is L2 (resistance arm). According to the lever principle, the linear displacement S of the stud and the arc length displacement s of the glue gate are related by S / s = L1 / L2. Simultaneously, the arc length displacement s of the glue gate is approximately equal to the change in the glue dispensing gap; therefore, the transmission ratio i = S / Δgap = L1 / L2. For example, if the lead is set to 1.75mm and the glue dispensing gap is set to 0.24mm for one rotation, then the lever arm L1 of the connecting rod is approximately 7 times the resistance arm L2. That is, the movement of the stud, through the lever effect, causes a smaller glue gate displacement to correspond to a larger axial movement of the stud, thereby achieving high-precision adjustment. Of course, when the lead of the transmission component 3 is 2mm, its glue dispensing gap can also be set to 0.24mm; this only requires adjusting the length relationship between the lever arm and the resistance arm.

[0053] The pointer seat 1 is an L-shaped fixing block made of aluminum alloy or steel. One end of the L-shaped fixing block is fixed to the top of the solvent box by four screws, and the other end has a 30mm diameter shaft hole. An arrow-shaped pointer is laser-engraved on the pointer seat 1. The main scale of the annular scale marking 20 on the outer circumference of the rotating ring 2 is 0.2mm / division, and the secondary scale is 0.02mm / division. To provide smooth rotation, in one specific embodiment, a deep groove ball bearing is also built into the shaft hole of the pointer seat 1 for mounting the rotating ring 2. The transmission component 3 is an M12×1.75 fine thread stud or an M12×1.75 machine thread. The spring 6 is a 65Mn cylindrical helical spring 6 with a wire diameter of 0.7mm and a free length of 33mm. It is sleeved on the outer circumference of the stud, and its two ends abut against the end face of the sleeve and the first side wall 11 of the pointer seat 1, respectively. The locking component 5 is an M5 set screw, which is housed in the groove of the rotating ring 2 and tightens the stud through the M5 threaded hole on the sleeve.

[0054] When the visual adjustment structure is applied to the glue application mechanism 7, the adjustment process can be divided into initial state, usage state, and calibration, as detailed below:

[0055] Initial state adjustment is applicable before the first use of the glue application mechanism 7, or before changing the glue type or board specifications. The specific steps are as follows:

[0056] 1) Before adjustment, the glue door 73 is in the closed position by default (i.e., the glue door 73 is tightly fitted with the glue application shaft 72), and the glue discharge gap is 0mm in the reference state; the annular scale mark 20 of the rotating ring 2 is zeroed, the indicator part 13 of the pointing seat 1 is aligned with the "0" scale line of the rotating ring 2, the locking part 5 is in the pre-tightened state and fixes the position of the transmission part 3.

[0057] 2) According to the preset glue dispensing volume requirement (such as a target glue dispensing gap of 0.20mm), the operator rotates the rotating ring 2 clockwise; through the circumferential linkage between the locking part 5 and the transmission part 3, the rotating ring 2 drives the transmission part 3 to rotate synchronously. Since the transmission part 3 and the pointing seat 1 are threadedly engaged, the transmission part 3 moves axially towards the transmission rod, thereby pushing the transmission rod to drive the glue gate 73 away from the glue application shaft 72, increasing the glue dispensing gap.

[0058] 3) When the indicator part 13 of the pointer seat 1 is aligned with the target scale (e.g., 0.20mm) of the annular scale mark 20 of the rotating ring 2, stop rotating the rotating ring 2 to complete the preset adjustment of the initial glue dispensing gap.

[0059] It should be noted that the 0mm dispensing gap described in this invention is not an absolute zero gap in a physical sense, but rather refers to a critical state where the glue gate 73 and the glue application shaft 72 are so closely fitted that effective glue dispensing is impossible. In practical applications, due to the influence of process parameters such as glue viscosity and temperature, different types of glue have different critical gap values ​​for reaching the point where glue dispensing is impossible (for example, high-viscosity glue cannot flow at a small gap, while low-viscosity glue requires an even smaller gap to block dispensing). To facilitate a unified description and quantitative understanding of the adjustment amount of the dispensing gap, this invention defines the aforementioned critical state of no glue dispensing as a dispensing gap of 0mm, as the reference zero point for subsequent adjustment scale markings.

[0060] The status adjustment method is used during the glue application process to dynamically adjust the glue dispensing amount based on process parameters such as board thickness and glue application width, ensuring matching with real-time working conditions. The specific steps are as follows:

[0061] 1) Before adjustment, the glue gate 73 is in the working position (e.g., the current glue dispensing gap is 0.15mm), the indicator 13 points to the corresponding scale (0.15mm) of the rotating ring 2, and the locking member 5 is in the locked state to lock the position of the transmission member 3 and maintain the current glue dispensing gap stable.

[0062] 2) When the working conditions change (such as changing the edge banding tape specification, the glue dispensing gap needs to be reduced from 0.15mm to 0.1mm), the operator rotates the rotating ring 2 counterclockwise; through the circumferential linkage of the locking part 5, the rotating ring 2 drives the transmission part 3 to rotate in the opposite direction, and the transmission part 3 moves axially away from the transmission rod, pushing the transmission rod to drive the glue gate 73 to move closer to the glue application shaft 72, thereby reducing the glue dispensing gap.

[0063] 3) When the indicator 13 is aligned with the target scale (e.g., 0.1mm) of the rotating ring 2, stop rotating the ring 2 to complete the dynamic adjustment of the glue dispensing gap and ensure that the glue dispensing amount matches the new working condition.

[0064] The calibration process is used to eliminate adjustment errors caused by mechanical transmission backlash and cumulative component deformation after long-term use. Adjustment accuracy is ensured by resetting the glue dispensing gap reference zero point. The specific steps are as follows:

[0065] 1) Start the power source and drive the transmission rod to move the glue door 73 to the initial closed position (i.e., the critical state where the glue door 73 and the glue application shaft 72 are tightly fitted), and keep the glue door 73 in a stable and taut state.

[0066] 2) Loosen the locking part 5 and manually rotate the transmission part 3 to move it axially until the transmission part 3 abuts against the transmission rod and the transmission rod can no longer drive the glue door 73 to move towards the glue application shaft 72 (that is, the transmission part 3 and the transmission rod form a rigid abutment).

[0067] 3) Rotate the rotating ring 2 to precisely align the "0" mark of the annular scale mark 20 with the indicator part 13 of the pointer seat 15, and then tighten the locking part 5 to fix the position of the transmission part 3 to complete the reference zero point calibration.

[0068] Example 2

[0069] like Figure 10 As shown, Figure 10 This is a schematic diagram of the existing tracking mechanism 8. The tilt angle adjustment of the trimming motor in the trimming mechanism has been changed from the original adjustment shaft 812 to a visual adjustment structure. Please refer to [link / reference]. Figure 11 and Figure 12 The tracking mechanism 8 includes a tracking component 81, which includes an adjusting plate 810, a tracking motor 811, and an adjusting shaft 812. The rotating shaft of the tracking motor 811 is equipped with a trimming blade. The adjusting plate 810 has two parallel slits 810a and an arc-shaped groove 810b. The two slits 810a are connected through the arc-shaped groove 810b, thereby cutting the adjusting plate 810 into an outer plate 810d and an inner plate 810c. The inner plate 810c is used to install the tracking motor 811. The pointing seat 1 is installed on the side of the outer plate 810d away from the tracking motor 811 and is fixed by bolts. The transmission component 3 passes through the inner plate 810c and abuts against the tracking motor 811. By rotating the rotating ring 2, the tilt angle of the tracking motor 811 can be adjusted, thereby adjusting the trimming angle.

[0070] Example 3

[0071] like Figure 13 As shown, Figure 13 This is a schematic diagram of the existing polishing mechanism 9, which includes an upper polishing assembly and a lower polishing assembly with identical structures. The upper polishing assembly includes a mounting plate 91, a polishing motor 92, a mounting base 93, an adjusting screw 94, and a mounting block 95. In this embodiment 3, a visual adjustment structure is used to replace the adjusting screw 94 of the original structure. Specifically, the pointing seat 1 is welded to the top of the mounting base 93, the scale range of the rotating ring 2 is 0-10mm (0.2mm per division), and the transmission component 3 is connected to the mounting block 95 through a fisheye bearing. By rotating the rotating ring 2, the height direction of the polishing motor 92 can be adjusted, thereby adjusting the height of the polishing motor 92.
