Description

Technical Field

[0001] This utility model relates to the field of woodworking machinery and equipment technology, and in particular to a pressure roller balancing device for an edge banding machine. Background Technology

[0002] Edge banding is a crucial step in the manufacturing process of panel furniture. Its purpose is to cover and beautify the edges of the panels to enhance their durability and appearance. During the edge banding process, the pressure roller assembly on the edge banding machine plays a vital role, responsible for applying continuous and uniform pressure to the edge banding strip that has just been coated with hot melt adhesive, ensuring that the edge banding strip can be firmly and tightly bonded to the edge of the panel.

[0003] In traditional edge banding machines, the pressure roller assembly is designed as a rigid structure or a structure with simple overall elastic compensation. For standard, flat boards, this structure can meet the basic pressing requirements. However, with the increasing diversification and personalization of furniture design, more and more boards with irregular edges such as curves and waves are appearing. When the traditional pressure roller assembly faces such non-linear edges, its structural limitations become apparent. Since the pressure of all the pressure rollers cannot be adjusted independently, some pressure rollers may be suspended or have insufficient pressure when pressing the concave part of the curve, while other pressure rollers may have excessive pressure when pressing the convex part. This uneven pressure phenomenon seriously affects the edge banding quality, leading to local poor adhesion, gaps, or even the edge banding strip falling off.

[0004] There is also a need for beveled edge banding in the processing of boards. Existing pressure roller devices can only provide pressing force perpendicular to the plane of the board. When facing an edge with bevels, the pressure roller cannot effectively fit parallel to the bevel, resulting in incorrect pressing force direction. Similarly, it cannot guarantee the bonding strength of the edge banding strip at the bevel position.

[0005] Therefore, this utility model proposes a pressure roller balancing device for an edge banding machine to overcome the shortcomings of the prior art. Summary of the Invention

[0006] In view of the problems existing in the edge banding machine pressure roller balancing device, such as uneven pressing and poor quality due to the inability to independently adjust the pressure when processing irregular edge boards, and the single function that is difficult to adapt to the requirements of beveled edge banding process, this utility model aims to provide an edge banding machine pressure roller balancing device with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a pressure roller balancing device for an edge banding machine, including: a base plate, a base, a mounting platform, a pressure roller, a cavity, a slider, a fixed shaft, a cylinder, and a rotating mechanism.

[0008] The cylinder has a telescopic rod, and the rotating mechanism consists of an L-shaped support, a rotating shaft, and a power supply component.

[0009] Furthermore, the mounting platform has a cavity, the slider is slidably connected to the inside of the cavity, the pressure roller is rotatably connected to the slider through the fixed shaft, and the end of the telescopic rod of the cylinder is fixedly connected to the slider; at the same time, the L-shaped support is hinged between the base and the mounting platform, the rotating shaft is rotatably connected to the L-shaped support and fixedly connected to the mounting platform, and the power supply component is driven by the rotating shaft to drive its rotation.

[0010] Preferably, a rubber ring is elastically wrapped around the outer circumference of the pressing roller. As the interface that directly contacts the sheet material, the rubber ring can provide elastic buffering during pressing, realize flexible pressing and protect the surface of the sheet material.

[0011] Preferably, the L-shaped support column is provided with a fixing ring and a rotating groove. While the rotating shaft is rotatably inserted inside the fixing ring, its shaft body also passes through the rotating groove. The rotation range of the rotating mechanism is limited by the arc length of the rotating groove, thus ensuring the stability and safety of the rotation.

[0012] Preferably, the bottom of the mounting platform is also provided with a fixing button, and one end of the rotating shaft is securely fixed to the mounting platform through the fixing button. This design ensures that the rotational torque can be accurately and effectively transmitted to the entire mounting platform.

[0013] Preferably, the power supply component includes a mounting slot formed at the bottom of the mounting platform and a motor fixed inside the mounting slot. The output end of the motor is fixedly connected to the rotating shaft, forming a compact and direct drive unit that saves installation space and improves response speed.

[0014] Preferably, the mounting platform has multiple cavities along its length, and each cavity is equipped with an independent set of sliders, pressure rollers and cylinders, thereby forming a multi-point independently controlled pressure roller array to adapt to the processing of plates of different widths or complex shapes.

[0015] Preferably, the cylinder, telescopic rod, cavity, slider, fixed shaft and pressure roller together constitute a complete balancing mechanism unit, and each unit works in concert to achieve precise and stable pressing of the edge of the sheet metal.

[0016] This utility model has the following beneficial effects: 1. This utility model solves the problem of uneven pressure and poor edge banding quality when processing irregular or uneven thickness boards by setting an independent balancing mechanism consisting of a cylinder, telescopic rod and slider for each pressing roller.

[0017] 2. This utility model, by setting up a rotating mechanism consisting of an L-shaped support column, a rotating shaft and a motor, enables the mounting platform that carries all the pressure rollers to rotate at an overall angle relative to the base, which solves the problem that the pressure roller device in the prior art is difficult to adapt to the special bevel sealing process requirements, and achieves the expansion of device function to meet the special operation requirements such as bevel sealing.

[0018] 3. This utility model solves the problem that rigid pressure rollers may damage the surface of the board or cause poor pressing due to minor unevenness in the prior art by covering the outer circumference of the pressure roller with an elastic rubber ring and cooperating with the dynamic pressure adjustment of the cylinder. It achieves a combination of flexible pressing and active pressure control, which further improves the edge sealing stability and bonding quality while protecting the board.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0022] Please refer to Figures 1 to 4This utility model provides a pressure roller balancing device for an edge banding machine, which aims to solve the problem in the prior art that the edge banding pressure roller has poor adaptability to irregular boards, resulting in uneven pressing and failing to meet the requirements of the beveled edge banding process.

[0023] like Figure 1 , Figure 2 and Figure 3 As shown, a pressure roller balancing device for an edge banding machine includes a base plate 1 and a base 2 fixed to the top of the base plate 1. The base plate 1 and the base 2 together form the installation and support foundation of the entire device. The device further includes a mounting platform 301, which is hinged to the base 2 via a rotating mechanism 4. At the same time, a balancing mechanism 3 is integrated on the mounting platform 301. The function of the balancing mechanism 3 is to achieve stable and flexible pressing of the sheet material, while the rotating mechanism 4 is used to drive the mounting platform 301 together with the entire balancing mechanism 3 above it to rotate at a specific angle.

[0024] Specifically, refer to Figure 1 , Figure 3 and Figure 4 The balancing mechanism 3 is constructed as follows: Multiple cavities 304 are formed along the length of the mounting platform 301, and a slider 305 is slidably connected inside each cavity 304; a pressure roller 307 is rotatably connected to the slider 305 via a fixed shaft 306, allowing the pressure roller 307 to roll freely while moving linearly with the slider 305; a rubber ring 308 is elastically wrapped around the outer circumference of the pressure roller 307, serving as the interface directly in contact with the plate, utilizing its elasticity to achieve flexible pressing; to drive the slider 305, a cylinder 302 is mounted on the mounting platform 301, and the cylinder 302 has a telescopic rod 303, the output end of which is fixedly connected to one end of the slider 305. By controlling the telescopic movement of the cylinder 302, the position of the slider 305 within the cavity 304 can be precisely adjusted, thereby controlling the pressing pressure and position of the pressure roller 307.

[0025] Furthermore, referring to Figure 1 , Figure 2 and Figure 3The rotating mechanism 4 is constructed as follows: one end of the L-shaped support column 401 is hinged to the base 2, and the other end is hinged to the bottom of the mounting platform 301, serving as a connecting and supporting skeleton; a fixing ring 402 is provided on the L-shaped support column 401, and a rotating groove 404 for limiting the rotation range is also provided; the rotating shaft 403 rotatably passes through the inside of the fixing ring 402, and its shaft body passes through the rotating groove 404; one end of the rotating shaft 403 is fixedly connected to the bottom of the mounting platform 301 by a fixing button 405, realizing the connection between the rotating shaft 403 and the mounting platform 301. 1. Linkage; To provide rotational power, the device is also equipped with a power supply component 406. The power output end of the power supply component 406 is connected to the rotating shaft 403. The power supply component 406 itself includes a mounting groove 4061 opened at the bottom of the mounting platform 301, and a motor 4062 fixedly installed inside the mounting groove 4061. The output end of the motor 4062 is fixedly connected to the other end of the rotating shaft 403. Driven by the motor 4062, the rotating shaft 403 can be rotated, thereby causing the entire mounting platform 301 to deflect at an angle around the rotating shaft 403.

[0026] Please refer to Figure 3 and Figure 4 The cavity 304 on the mounting platform 301 has its inner wall precisely machined into a smooth guide surface, providing a stable and low-resistance linear motion track for the movement of the slider 305. The slider 305 has an external shape that matches the internal shape and size of the cavity 304. In the assembled state, the slider 305 slides inside the cavity 304. This fully enclosed cavity-slider 305 mating structure can constrain the degree of freedom of the slider 305 from multiple directions, ensuring that the slider 305 can still reciprocate without deviation when subjected to lateral forces from the pressure roller 307, thereby ensuring the stability of the pressing.

[0027] The cylinder 302 is mounted on the mounting platform 301 as a drive source. Its position ensures that the axis of motion of its telescopic rod 303 is parallel to the sliding direction of the slider 305 in the cavity 304. The end of the telescopic rod 303 is fixedly connected to one end of the slider 305 by means of welding or threaded connection, thereby directly and without loss transmitting the thrust or pull force generated by the cylinder 302 to the slider 305. By controlling the air intake and exhaust of the cylinder 302 through an external pneumatic control system, the telescopic rod 303 can be driven to extend or retract, thereby driving the slider 305 together with the pressure roller 307 rotatably connected thereon to move precisely within the stroke defined by the cavity 304. This direct drive structure responds quickly and can be adjusted in real time according to changes in the surface of the plate to maintain a constant pressing force.

[0028] As a preferred embodiment, in order to provide cushioning and protect the surface of the sheet during the pressing process, please refer to... Figure 1 and Figure 2The outer circumferential surface of the pressure roller 307 is elastically covered with a rubber ring 308. The rubber ring 308 is made of a material with good elasticity and wear resistance. When the pressure roller 307 comes into contact with the plate, it undergoes a small amount of elastic deformation, which can effectively absorb the impact caused by the slight unevenness of the plate surface, ensure the uniform transmission of the pressing force, and avoid leaving indentations on the plate surface.

[0029] As another preferred embodiment, to achieve a stable and reliable connection of the rotating mechanism 4, please refer to... Figure 3 A fixing ring 402 is integrally formed or fixedly connected to the L-shaped support column 401. At the same time, an arc-shaped rotating groove 404 is also opened on the L-shaped support column 401. The shaft of the rotating shaft 403 is rotatably inserted into the inner hole of the fixing ring 402 and rotates smoothly through a bearing or bushing. The shaft of the rotating shaft 403 also passes through the rotating groove 404. The arc length of the rotating groove 404 determines the maximum rotation angle of the rotating shaft 403, thereby providing a precise range limit for the deflection of the entire mounting platform 301.

[0030] As another preferred embodiment, to ensure a secure connection between the rotating shaft 403 and the mounting platform 301, please refer to... Figure 2 The bottom of the mounting platform 301 is integrally formed or fixedly connected with a thickened fixing button 405; one end of the rotating shaft 403 is fixed to the fixing button 405 by means of a key connection or spline connection, so that the rotational torque of the rotating shaft 403 can be transmitted to the mounting platform 301 without deviation.

[0031] As another preferred embodiment, in order to compactly integrate the power supply component 406 onto the device, please refer to... Figure 2 The power supply component 406 specifically includes a mounting groove 4061 formed at the bottom of the mounting platform 301, and a motor 4062 fixedly installed inside the mounting groove 4061. The shape and size of the mounting groove 4061 are adapted to the housing of the motor 4062, which can provide good limiting and protection for the motor 4062. The output shaft of the motor 4062 is connected to the other end of the rotating shaft 403 through a coupling or directly fixed, forming a direct transmission path, which improves transmission efficiency and response speed.

[0032] As an extended implementation method, to improve processing efficiency and adaptability to wide plates, please refer to... Figure 1 Multiple independent pressing units can be arranged side by side along the length of the mounting platform 301, that is, multiple cavities 304 are provided, and each cavity 304 is provided with an independent slider 305, a pressing wheel 307 and a cylinder 302 that drives its movement. These pressing units can be controlled collaboratively or independently by a centralized control system.

[0033] Working principle: The pressure roller balancing device is installed on one side of the edge banding machine via the base plate 1 at the bottom of the base 2. The mounting platform 301 has multiple cavities 304, inside which slide and engage sliders 305. Multiple pressure rollers 307 are fixed to the sliders 305 via fixed shafts 306 to ensure that there is no displacement during edge banding. The surface of the pressure rollers 307 is covered with a rubber layer, forming a rubber ring 308, which directly contacts the board material. It has a certain degree of elasticity, enabling flexible and stable pressing of the edge banding, ensuring edge banding quality and efficiency. The telescopic rod 303 at the output end of the cylinder 302 is fixedly connected to one end of the slider 305, so that the cylinder 302 can control the position of the slider 305 in the cavity 304. When performing edge sealing extrusion, the output size of the cylinder 302 can be adjusted in real time according to the feedback from the pressure roller 307 to maintain the stability and uniformity of the pressure roller 307. The balance mechanism 3 is equipped with a single pressure roller 307 with a single cavity 304 and cylinder 302, which can be adjusted individually. It can effectively extrude and seal irregular plates, improving the adaptability of the device. Furthermore, the device is equipped with a rotating mechanism 4. The base 2 and the mounting platform 301 are hinged together by an L-shaped support column 401. Specifically, a fixing ring 402 is provided on the L-shaped support column 401, and a rotating shaft 403 is rotatably connected inside the fixing ring 402. One end is fixed to a fixing button 405 at the bottom of the mounting platform 301, and the other side is connected to the power supply component 406. That is, the motor 4062 is fixed in the mounting groove 4061 at the bottom of the mounting platform 301. The output end of the motor 4062 is connected to the rotating shaft 403, and the motor 4062 can control the rotating shaft 403 to rotate at a certain angle in the rotating groove 404, so that the pressing roller 307 and the sealing opening of the edge banding machine form a certain angle, which is used to meet the special situation of needing beveled edge banding and extrusion, and expand the functionality of the device.
