Edge band slotting device

Abstract

This utility model discloses a grooving device for edge banding tape, including a frame, a positioning mechanism, and a pressure roller assembly. The frame is equipped with a grooving mechanism, which includes a first drive motor and a cutter head disposed at the drive end of the first drive motor. The positioning mechanism includes a positioning plate and a first drive member connected to the positioning plate. The pressure roller assembly cooperates with the positioning plate to press the edge banding tape for positioning. When the first drive member actuates and drives the positioning plate to move closer to the cutter head, it can push the pressure roller assembly to move, and move the edge banding tape closer to the cutter head, so that the cutter head can groove the edge banding tape. Thus, through the coordinated action of the positioning mechanism and the pressure roller assembly, the edge banding tape is precisely pushed from the opposite side towards the cutter head, ensuring that a set thickness of uncut portion is always retained during the grooving process, without relying on a fixed cutting depth setting. Regardless of the thickness tolerance of the edge banding tape, the cutter head only cuts the portion exceeding the reserved thickness, avoiding cutting through or insufficient remaining thickness.

Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, specifically to a grooving device for edge banding. Background Technology

[0002] In furniture manufacturing and panel processing, edge banding is typically applied to enhance the aesthetics and durability of panel edges, serving both decorative and protective functions. In edge banding of irregularly shaped furniture, especially when banding panels with thicker edges or unique structures, grooves are often pre-cut into the edge banding. This allows it to fit snugly against the vertical and inclined surfaces of the irregularly shaped area after bending, ensuring flatness and strong adhesion.

[0003] However, existing edge banding grooving devices mostly use a cutter to directly position and cut the edge banding to a set depth. For example, when processing a 2mm thick PVC edge banding, approximately 0.5mm of uncut thickness is usually required to avoid cutting through, meaning a cutting depth of 1.5mm is necessary. However, due to the inherent thickness tolerance of the edge banding, when cutting uniformly to the set depth, the remaining thickness in some areas may be less than 0.5mm, or even cut through in extreme cases. This defect not only damages the integrity of the edge banding and wastes raw materials but also weakens its structural strength, affects the bonding effect, and ultimately leads to a decline in the appearance and consistency of the finished product. Utility Model Content

[0004] To overcome the shortcomings of the prior art, this utility model provides a grooving device for edge banding tape. Through the coordinated action of the positioning mechanism and the pressure roller assembly, the edge banding tape is precisely pushed from the opposite side towards the cutter head, ensuring that a predetermined thickness of uncut portion is always retained during the grooving process, without relying on a fixed cutting depth setting.

[0011] Furthermore, the table surface is provided with a first guide plate and a second guide plate, and there is a gap between the first guide plate and the second guide plate, and the gap forms a through groove for the edge banding tape to pass through.

[0019] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0020] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the module or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0022] like Figure 1-6The edge banding tape grooving device shown includes a frame 1, a positioning mechanism, and a pressure roller assembly 3. The frame 1 is equipped with a grooving mechanism, which includes a first drive motor 21 and a cutter head 2 disposed at the driving end of the first drive motor 21. The positioning mechanism includes a positioning plate 42 and a first drive member 41 connected to the positioning plate 42. The pressure roller assembly 3 cooperates with the positioning plate 42 to press the edge banding tape to achieve positioning. When the first drive member 41 is activated and drives the positioning plate 42 to move closer to the cutter head 2, it can push the pressure roller assembly 3 to move and move the edge banding tape closer to the cutter head 2 so that the cutter head 2 can groove the edge banding tape.

[0023] During operation, the first driving component 41 actuates and drives the positioning plate 42 to move towards the cutter head 2, while simultaneously pushing the pressure roller assembly 3 to move synchronously. This precisely pushes the edge banding tape from the back towards the cutter head 2, allowing the cutter head 2 to cut grooves into the edge banding tape. The positioning mechanism and the pressure roller assembly 3 work together to ensure that a set thickness of uncut portion is always retained during the grooving process, without relying on a fixed cutting depth setting. Regardless of the tolerance of the edge banding tape thickness, the cutter head 2 only cuts the portion exceeding the reserved thickness, thereby effectively avoiding cutting through the edge banding tape or causing insufficient remaining thickness, improving the stability of processing and the quality of finished products.

[0024] See Figure 2 The device also includes a platform 11, on which a mounting base 4 is fixed. A first driving component 41 is mounted on the mounting base 4. The mounting base 4 is provided with a sliding sleeve 43, and the positioning plate 42 is provided with a sliding rod 421 that is slidably connected to the sliding sleeve 43 to achieve smooth movement of the positioning plate 42. The platform 11 is also provided with a fixing plate 115 arranged opposite to the positioning plate 42, and a gap is formed between the two for the edge banding tape to pass through, thereby effectively limiting its travel path during the pushing and grooving process of the edge banding tape, preventing deviation, ensuring stable movement, and improving grooving accuracy and processing consistency.

[0025] In this embodiment, a protective cover 111 is also provided on the table 11 to protect the cutting head 2. The protective cover 111 can effectively block flying sawdust, debris and other debris during grooving operations, preventing them from spilling and causing environmental pollution or injury to operators. At the same time, it can prevent personnel from accidentally touching the cutting head when not in operation, thereby improving the overall safety and reliability of the equipment. In addition, the protective cover 111 can also reduce the noise generated by the high-speed operation of the cutting head to a certain extent, improving the working environment.

[0026] See Figure 3-4The pressure roller assembly 3 includes a first pressure roller component 31 and a second pressure roller component 32. The first pressure roller component 31 includes a first connecting rod 311, a first elastic element 312 sleeved on the first connecting rod 311, and a first pressure roller 313 connected to the first connecting rod 311. One end of the first connecting rod 311 is provided with a connecting shaft 3111, and the first pressure roller 313 is rotatably connected to the connecting shaft 3111. The second pressure roller component 32 includes a pressure roller bracket 323, a second elastic element 322, and a second pressure roller 324, which rotates. Connected to the pressure roller bracket 323, the pressure roller bracket 323 has a second connecting rod 321 at both ends, and two second elastic elements 322 are respectively sleeved on the two second connecting rods 321. When the positioning plate 42 pushes the pressure roller assembly 3 to move, the first pressure roller 313 overcomes the elastic force of the first elastic element 312 and compresses the first elastic element 312, and the second pressure roller 324 overcomes the elastic force of the second elastic element 322 and compresses the second elastic element 322 through the pressure roller bracket 323, thereby realizing reliable clamping and flexible pressing of the edge banding.

[0027] Furthermore, the first pressure roller 31 is provided in two sets, which are respectively distributed on both sides of the second pressure roller 32. This can improve the pressing stability of the first pressure roller 313 on the edge banding, and also make the force on both sides of the positioning plate 42 more balanced, effectively preventing the edge banding from running off-center or shifting during the grooving process, thereby ensuring the accuracy and consistency of the grooving position, and improving the stability of processing quality and finished product appearance.

[0028] See Figure 5 A fixed base 5 is provided on the table 11, and a through hole 51 is provided on the fixed base 5 for the edge banding tape to pass through. A second driving component 52 is installed on the frame 1, and its driving end is slidably connected to a cutting blade 53 on one side of the fixed base 5. When the second driving component 52 is running, it can drive the cutting blade 53 to move smoothly in a set direction and accurately cut the edge banding tape passing through the through hole 51. This ensures that the edge banding tape can be cut directly after the grooving process is completed, realizing integrated processing of grooving and cutting. The through hole 51 can also restrict and guide the position of the edge banding tape, avoiding deviation or warping during the cutting process, thereby improving the accuracy of the cutting position and the flatness of the cut, reducing burrs and waste, and significantly improving processing efficiency and finished product quality.

[0029] See Figure 6 The frame 1 is equipped with a third driving component 71 and a movable seat 7 connected to the driving end of the third driving component 71. The movable seat 7 is equipped with rollers 72. The frame 1 is equipped with a second driving motor 12, and the rollers 72 are connected to the second driving motor 12 through a first universal drive shaft 721. The third driving component 71 drives the movable seat 7 to move, so that the rollers 72 abut against the edge sealing tape. The second driving motor 12 drives the rollers 72 to rotate to push and smoothly roll and adhere the edge sealing tape to the workpiece.

[0030] In this embodiment, the movable seat 7 is arranged at an angle, causing the roller 72 to tilt accordingly. This allows for better contact with the inclined surface of the workpiece during the edge sealing process, achieving uniform pressing and tight adhesion of the edge sealing tape, thus improving edge sealing quality and bonding strength. In other application scenarios, the movable seat 7 and roller 72 can also be arranged vertically to accommodate edge sealing operations on the vertical surface of the workpiece, thereby enhancing the adaptability and diversified processing capabilities of the device.

[0031] Furthermore, the table 11 is provided with a first guide plate 116 and a second guide plate 117, which form a through groove for the edge banding tape to pass through, thereby guiding and precisely positioning the edge banding tape. The table 11 is also provided with a baffle 118 to block the through groove, preventing the edge banding tape from shifting or lifting during the feeding process, thereby ensuring the stability and consistency of the cutting position.

[0032] Preferably, guide wheels 113 and guide plates 114 can also be provided on the table 11. The rotational support of the guide wheels and the limiting cooperation of the guide plates can further improve the stability of the edge banding feed, reduce the shaking during the feeding process, and ensure the grooving quality.

[0033] In this embodiment, the table 11 is also provided with a guide frame 112, which is used to provide pre-guidance before the edge banding tape enters the through groove, so that the edge banding tape can smoothly transition between the guide plates, effectively reducing the risk of jamming or bending, and improving processing continuity and work efficiency.

[0034] See Figure 1 The system also includes a gluing mechanism, comprising a first gluing component 8 for applying glue to the vertical surface of the workpiece and a second gluing component 9 for applying glue to the inclined surface of the workpiece. The first gluing component 8 has a vertically arranged first gluing shaft 81, and the second gluing component 9 has an inclinedly arranged second gluing shaft 91. Specifically, it also includes a third drive motor 13 mounted on the frame 1. The first gluing shaft 81 is connected to the third drive motor 13 via a second universal joint drive shaft 82, and the second gluing shaft 91 is connected to the third drive motor 13 via a third universal joint drive shaft 92, so as to achieve multi-sided synchronous gluing, improve gluing uniformity and production efficiency.

[0035] Furthermore, the table 11 is also equipped with a drive wheel 61, which is used to smoothly push the edge banding tape to the cutting blade 53 before it reaches the cutting blade, ensuring that the edge banding tape remains taut and straight before cutting, thereby avoiding inaccurate cutting position due to slack or offset. The drive wheel 61 is driven by the fourth drive motor 6. Through stable rotation speed and pushing force, the accuracy and consistency of the cutting action can be improved, reducing the difficulty of subsequent workpiece bonding caused by rough cut or dimensional deviation, while also helping to improve processing efficiency and product quality.

[0036] In summary, the edge banding tape grooving device of this invention, through the coordinated action of the positioning mechanism and the pressure roller assembly 3, precisely pushes the edge banding tape from the opposite side towards the cutter head 2, ensuring that a predetermined thickness of uncut portion is always retained during the grooving process, without relying on a fixed cutting depth setting. Regardless of any tolerance in the thickness of the edge banding tape, the cutter head 2 only cuts the portion exceeding the pre-reserved thickness, avoiding situations such as cutting through or insufficient remaining thickness.

[0037] This utility model of edge banding tape grooving device can achieve tight fit and firm adhesion between the bent and irregularly shaped areas while ensuring the integrity of the edge banding tape, thus improving the edge banding quality and product consistency. Furthermore, this structure reduces reliance on the precision of the cutter height adjustment, lowers setup time, and improves processing efficiency and production stability, making it particularly suitable for batch processing of edge banding tapes with slight thickness variations.

When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to the other component.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the module or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.
