Description

Technical field

[0001] The invention relates to an edge strip cutting device of an edge banding machine. State of the art

[0002] Existing edgebanding machines can transport a panel via a conveyor belt and a set of pressure rollers. Simultaneously, the edgebanding conveyor mechanism transports an edgeband that is to be glued to one edge of the panel. The excess edgebanding is cut off by an edgebanding cutting mechanism.

[0003] The conventional edgebanding cutting mechanism can only be used for cutting edgebands. Grinding requires the edgebanding machine to be equipped with a grinding mechanism, or an additional grinding process must be performed, leading to problems such as bulky equipment and reduced production efficiency. Furthermore, the existing grinding mechanism must adjust the cutting depth by changing the position of the blade. Operation is cumbersome, and problems such as inaccurate and unreliable blade positioning are easily encountered. Object of the invention

[0006] Fig. Figures 1 to 9 show the edge strip cutting device 1 of an edge banding machine of the present invention, comprising: a base 10, a cutting arrangement 20, at least one holding arrangement 70 and a first displacement mechanism 30. The edge banding machine has a conveying mechanism 3 for conveying a panel 2 along a first direction D1.

[0007] The base 10 is arranged on one side of the conveying mechanism 3. The cutting assembly 20 comprises a carrier 21, at least one blade 22, and a drive motor 23. The at least one blade 22 is arranged on the carrier 21 and has a plurality of cutting teeth 221. Each cutting tooth 221 has a first cutting section 222 and a second cutting section 223. The second cutting section 223 is located on one side of the first cutting section 222 in the first direction D1 and has an arcuate surface 223a. The drive motor 23 can drive the at least one blade 22 such that it rotates about a rotation axis R parallel to the first direction D1. The at least one holding assembly 70 is arranged on the side of the carrier 21 facing the conveying mechanism 3. The first displacement mechanism 30 is located between the base 10 and the cutting assembly 20.The first displacement mechanism 30 can move the at least one blade 22 back and forth along a second direction D2 transverse to the first direction D1, so that the arc surface 223a can contact and cut the edge strip 2a of the plate 2. Each holding arrangement 70 includes a holding surface 711 for holding the plate. The at least one blade 22 partially protrudes from the holding surface 711. The position of the holding surface 711 can be adjusted relative to the carrier 21 in the second direction D2. This allows the relative position of the at least one blade 22 and the plate 2 to be changed to achieve the effect of adjusting the cutting depth.

[0008] The support 21 has a support surface 211 and an opening 212 in the support surface 211. At least one retaining arrangement 70 is located on the support surface 211. The at least one blade 22 projects through the opening 212 of the support surface 211. The retaining arrangement 70 includes a retaining plate 71 and at least one adjusting element 72, which is connected between the retaining plate 71 and the base 21. The retaining plate 71 forms the retaining surface 711. The at least one adjusting element 72 can be rotated to move the retaining surface 711 along the second direction D2. The retaining arrangement 70 also includes at least one elastic element 73, which is clamped between the retaining plate 71 and the base 21. In its normal state, the elastic element 73 presses against the retaining plate 71 in the opposite direction of the support 21. The retaining plate 71 is made of metal.The retaining plate 71 also has two inclined surfaces 712 connected to two opposite sides of the retaining surface 711. The retaining surface 711 extends parallel to the first direction D1. The retaining arrangement 70 includes two adjusting elements 72, spaced apart, which penetrate the retaining plate 71, and several elastic elements 73. Each adjusting element 72 is a screw element bolted to the support 21. Each elastic element 73 is a spring attached to one of the adjusting elements 72. If the cutting depth of the edge strip 2a is to be adjusted, the adjusting elements 72 can be tightened or loosened so that the retaining surface 711 is moved along the second direction D2 to change the contact area of ​​the second cutting section 223 and the edge strip 2a.

[0009] The blade 22 is a circular saw blade. The second cutting section 223 is located on the radial inner side of the first cutting section 222. The cutting assembly 20 also includes a power transmission shaft 24, which is arranged at the base 21. The drive motor 23 can rotate the power transmission shaft 24.

[0010] The first displacement mechanism 30 can move the at least one blade 22 along the second direction D2 between an initial position, a first cutting position, and a second cutting position. When the at least one blade 22 is in the initial position, the at least one blade 22 and the plate 2 do not affect each other, allowing the plate 2 to pass through. When the at least one blade 22 is in the first cutting position, the at least one first cutting section 222 acts on the edge strip 2a, cutting off the excess portion of the leading edge of the edge strip 2a. When the at least one blade 22 is in the second cutting position, the at least one second cutting section 223 acts on the edge strip 2a, cutting the corners of the cut surface of the edge strip 2a to form a desired arc surface.

[0011] The edgebanding device 1 of the edgebanding machine further comprises a push assembly 40 provided at the base 10. The push assembly 40 includes a push rod 41 and a second displacement mechanism 42. The push rod 41 is arranged between the at least one blade 22 and the conveying mechanism 3 and can hold the plate 2 in the first direction D1. The second displacement mechanism 42 can move the push rod 41 between a first position and a second position along a third direction D3 perpendicular to the first direction D1. When the push rod 41 is in the first position, the plate 2 can rest against the push rod 41 in the first direction D1. When the push rod 41 is in the second position, the push rod 41 and the plate 2 do not affect each other in the first direction D1.

[0012] The push rod 41 has a shaft 411 and two side plates 412 on opposite sides of the shaft 411. One end of each side plate 412 projects from the shaft 411 and is provided with a roller 413 to guide the displacement of the plate 2. Viewed along the radial direction of the at least one blade 22 ( Fig. 6) The second cutting sections 223 protrude from one of the side plates 412. The extension direction of the side plates 412 is perpendicular to the extension direction of the holding surface 711 and can each abut against two sides of the plate 2. The two side plates 412 are detachably arranged on the shaft 411.

[0013] The edge strip cutting device 1 further comprises a third displacement mechanism 50, which is arranged between the base 10 and the cutting assembly 20. It can adjust the height of the cutting assembly 20 relative to the conveying mechanism 3 along a vertical direction. The side strip cutting device 1 further comprises a fourth displacement mechanism 60. The base 10 is arranged on the fourth displacement mechanism 60. The fourth displacement mechanism 60 can move the base 10 parallel to the first direction D1.

[0014] The cutting assembly 20 includes two blades 22. Two holding assemblies 70 are spaced apart in the first direction D1. The two blades 22 are arranged between the two holding assemblies 70, spaced apart in the first direction D1. The push rod 41 is located between the two holding assemblies 70. The two blades 22 are spaced apart and rotationally fixed to the power transmission shaft 24, which simplifies the motor design and circuit configuration.
