Description

Technical Field

[0001] This utility model relates to the field of edge banding equipment, specifically to an edge banding component and edge banding machine for semi-handled edge banding. Background Technology

[0002] Figure 1 This is a partially enlarged schematic diagram of the half-handle structure of a cabinet door. In conventional straight-edge sealing operations, as the board is fed in, the annular pressing roller, through the rolling of its outer circle, presses the edge banding strip onto the side of the board. However, in the half-handle structure of the cabinet door, at the same cross-section (refer to...), Figure 1 (The marked reference line) means that the side profile of the board is no longer a straight edge. Existing pressing rollers cannot complete the edge sealing operation of this type of side, and manual edge sealing is often required, which results in high operating costs. Utility Model Content

[0032] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0033] Figure 2 This is a three-dimensional structural diagram of the edge-sealing component for half-handle edge sealing according to an embodiment of the present invention. Figure 3 This is a cross-sectional structural diagram of the edge-sealing component for half-handle edge sealing according to an embodiment of the present utility model.

[0034] Accordingly, this utility model embodiment provides an edge sealing assembly for semi-handled edge sealing, including an upper clamping plate 1, a rigid edge sealing wheel 2, a flexible edge sealing wheel 3, a tension spring 5, and a lower support mold 4;

[0035] The rigid sealing wheel 2 is a solid ring structure made of hard material, with a through hole on the inner side;

[0036] The flexible sealing wheel 3 is a hollow ring structure made of flexible material, with a through second hole on the inner side;

[0037] The lower support mold 4 is divided into several support parts along the axial direction. The outer contour of each support part is formed by rotating a preset generatrix around the axis of the lower support mold 4 to form a closed shape.

[0038] The flexible edge sealing wheel 3 is sleeved on the lower support mold 4, the rigid edge sealing wheel 2 is coaxially stacked on the flexible edge sealing wheel 3, the upper clamping plate 1 is pressed on the top surface of the rigid edge sealing wheel 2, the tension spring 5 is disposed in the first through hole and the second through hole, and the two ends of the tension spring 5 are respectively connected to the upper clamping plate 1 and the lower support mold 4.

[0039] It should be noted that the main function of the lower support mold 4 is to provide an outward driving force to the flexible edge-sealing wheel 3 from the inside. Since forces are reciprocal, the pressure exerted on the flexible edge-sealing wheel 3 from the outside will also be transmitted to the lower support mold 4. Combined with the tension of the tension spring 5 between the lower support mold 4 and the upper pressure plate, the lower support mold 4 can spontaneously move and reset according to the edge-sealing structure encountered by the flexible edge-sealing wheel 3. Due to the diversity of semi-handle structures, this utility model is designed for... Figure 1 The implementation principle of the edge sealing component of this utility model embodiment is explained by describing the type of semi-handle structure.

[0040] Correspondingly, the lower support mold 4 includes a first support part 11 located at the upper end, a second support part 12 located in the middle section, and a third support part 13 located at the lower end;

[0041] The first support part 11 is a cylindrical structure, and the cross-sectional diameter of the first support part 11 is less than or equal to the diameter of the first through hole;

[0042] The second support part 12 is a frustum structure. The top diameter of the second support part 12 is the same as the cross-sectional diameter of the first support part 11, and the bottom diameter of the second support part 12 is larger than the diameter of the first through hole.

[0043] The third support part 13 has a cylindrical structure, and the cross-sectional diameter of the third support part 13 is the same as the bottom diameter of the second support part 12.

[0044] In an optional implementation, by default, the outer diameter of the flexible edge sealing wheel 3 is larger than the outer diameter of the rigid edge sealing wheel 2.

[0045] In an optional implementation, by default, the diameter of the second perforation is smaller than the diameter of the first perforation.

[0046] Figure 4 A cross-sectional structural diagram of the edge banding assembly of this utility model performing a straight edge banding operation is shown. Specifically, due to the pressure from the straight edge of the board 30, the flexible edge banding wheel 3 is squeezed, and the squeezing force is transmitted to the lower support mold 4; since the outer surface of the frustum structure of the second support part 12 is an inclined surface, the vertical component of the squeezing force is too large, and the tension spring 5 will not pull up the lower support mold 4; similarly, based on the reaction force of the lower support mold 4, the flexible edge banding wheel 3 will apply pressure to the edge banding strip 31, so that the edge banding strip 31 can effectively adhere to the board 30.

[0047] Figure 5 This diagram shows a cross-sectional view of the edge banding assembly of this invention when performing a half-handle edge banding operation. Specifically, because the half-handle has a relatively concave stepped structure, the outer side of the flexible edge banding wheel 3 loses its support and expands outward. At the same time, due to the imbalance of forces, the tension spring 5 pulls up the lower support mold 4, and the second support part 12 and the third support part 13 with larger cross-sectional areas of the lower support mold 4 move upward. A new force balance is formed between the plate 30, the flexible edge banding wheel 3, and the lower support mold 4. The flexible edge banding wheel 3 deforms to squeeze and fill the step at the half-handle, and correspondingly, the edge banding strip 31 is pressed tightly onto the surface of the half-handle.

[0048] An optional implementation may also include a lifting drive mechanism;

[0049] The lifting drive mechanism is used to drive the lower support mold 4 to move along the axial direction of the first through hole and the second through hole.

[0050] In the foregoing description, the external force on the flexible edge sealing wheel 3 and the tension of the tension spring 5 are used to design the outer contour of the lower support mold 4. The lower support mold 4 can automatically realize the functions of movement and reset. In actual implementation, if the structure of the edge sealing object is more complex, the lifting drive mechanism can be used to assist in driving the movement of the lower support mold 4 to simplify the calculation workload.

[0051] In an optional embodiment, the flexible edge banding wheel 3 has granular protrusions on the side surface that contacts the rigid edge banding wheel 2. Specifically, both the flexible and rigid edge banding wheels contact the edge banding strip simultaneously. To ensure uniform rotational speed, the granular protrusions at the contact point between the flexible and rigid edge banding wheels 3 and 2 create a significant static friction force between them under the pressure of the lower support mold, hindering their relative rotation.

[0052] An optional implementation may also include a chuck;

[0053] The jaws include an upper jaw and a lower jaw. The upper jaw is rotatably connected to the upper clamping plate 1 at a first rotating shaft, and the lower jaw is rotatably connected to the lower support mold 4 at a second rotating shaft.

[0054] The first rotating shaft and the second rotating shaft are coaxial.

[0055] Optional implementations also include a jaw and a connecting shaft;

[0056] The jaws include an upper jaw and a lower jaw;

[0057] The connecting shaft is disposed in the first through hole and the second through hole, and the upper end of the connecting shaft extends out of the upper clamping plate 1, and the lower end of the connecting shaft extends out of the lower support mold 4.

[0058] Specifically, the edge sealing assembly of this utility model embodiment can be regarded as an edge sealing wheel as a whole. In the conventional implementation structure, the edge sealing wheel is generally rotatably connected to the clamp. The above provides two implementation methods of the clamp for reference.

[0059] Accordingly, this utility model also provides an edge banding machine, including the edge banding assembly described above. Specifically, in addition to the edge banding assembly, the edge banding machine generally also includes an adhesive dispensing assembly, an edge banding strip 31 supply assembly, and a drive assembly for driving the edge banding assembly to move.

[0060] In summary, this utility model embodiment provides an edge banding assembly and edge banding machine for edge banding of a semi-handle. The edge banding assembly adopts a composite structure of a flexible edge banding wheel 3 and a rigid edge banding wheel 2. At the same time, the lower support mold 4 is designed according to the semi-handle structure that needs to be edge banded. The automatic edge banding of the semi-handle is achieved by utilizing the tension of the tension spring 5 and the interaction force between the plate 30 and the flexible edge banding wheel 3, which has good implementation convenience.

[0061] The above provides a detailed description of an edge-sealing component and machine for half-handle edge sealing provided by the embodiments of this utility model. Specific examples have been used to illustrate the principle and implementation of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of ​​this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
