Technical Field

[0001] The invention relates to an edge banding processing device, in particular to a head and tail cutting device. Background Art

[0002] Artificial boards are made of wood or other non-wood plants, separated into various unit materials through mechanical processing, and then glued together with or without adhesives and other additives to form boards or molded products. Artificial boards are widely used in construction, car interior decoration, furniture manufacturing and other fields due to their large format, good structure, convenient construction, low expansion and contraction rate, stable size, uniform material and not easy to deform and crack.

[0003] In the artificial board, the four sides as the cutting surface, in order for the artificial board to achieve the ideal use effect and appearance effect, the four sides of the cut artificial board must be edge-sealed, and then the excess edge banding at both ends after edge sealing must be cut off through the head and tail cutting equipment.

[0004] For existing head and tail cutting equipment, especially when cutting the head and tail of the edge banding on the artificial board during continuous feeding, the vibration of the board during the cutting process can easily cause the effective part of the edge strip to be cut, affecting the appearance of the product. In addition, when completing the head cutting, the saw blade is only adjusted vertically to avoid collision, which can easily cause collision with the board. Summary of the invention

[0029] See also Figures 1 to 6 The present invention provides a head and tail cutting device, which is used for performing head cutting and tail cutting on the front and rear ends of the edge banding strip 200 on the plate 100. The head and tail cutting device includes a head trimming frame 10, a main guide rail 60 installed on the head trimming frame 10, a front cutting device 20 and a rear cutting device 30 installed on the main guide rail 60, a front positioning device 40 installed on the head trimming frame 10 and connected to the front cutting device 20, and a rear positioning device 50 installed on the head trimming frame 10 and connected to the rear cutting device 30. The front cutting device 20 and the rear cutting device 30 can be slidably adjusted along the main guide rail 60.

[0030] The feeding direction of the plate 100 to be processed is the X-axis direction, and the Y-axis direction is perpendicular to the X-axis direction in the horizontal plane. When the plate 100 to be processed is fed, an external manipulator or other clamping device presses the plate 100 and moves forward along the X-axis direction. During the head cutting and tail cutting process, the plate 100 keeps moving forward.

[0031] The main guide rail 60 is inclined, and the angle between the main guide rail 60 and the horizontal plane is 33° to 37°. Preferably, the angle between the main guide rail 60 and the horizontal plane is 35°. The main guide rail 60 with a slope of 35° can make the downward movement speed and downward pressure weight of the rear cutting device 30 on the main guide rail 60 more moderate, so that the rear cutting device 30 can better cut the edge strip 200 and make the incision more complete.

[0032] The front cutting device 20 includes a front slider 28, a front support plate 21 mounted on the front slider 28, a front Y-axis driving mechanism 22 mounted on the front support plate 21, a front linkage plate 23 mounted on the front Y-axis driving mechanism 22, a front X-axis driving mechanism 24 and a front mold 25 mounted on the front linkage plate 23, a front cutting motor 26 mounted on the front X-axis driving mechanism 24, and a front saw blade 27 mounted on the front cutting motor 26. The front positioning device 40 is connected to the front support plate 21, and the front slider 28 is slidably mounted on the main guide rail 60. Through the front slider 28 mounted on the main guide rail 60, the front positioning device 40 drives the entire front cutting device 20 to be adjusted along the extension direction on the main guide rail 60. In this embodiment, the front positioning device 40 is a cylinder, the rear end of the cylinder body 41 of the front positioning device 40 is movably mounted on the head frame 10, and the front end of the piston rod 42 of the front positioning device 40 is movably mounted on the front support plate 21.

[0033] The front Y-axis driving mechanism 22 and the front X-axis driving mechanism 24 both adopt the cooperation mode of the guide rail (221, 241) and the slider (222, 242), and adopt the cylinder (223, 243) to drive the slider (222, 242) to shift, wherein the front linkage plate 23 is installed on the slider 222 of the front Y-axis driving mechanism 22, and the front cutting motor 26 is installed on the slider 242 of the front X-axis driving mechanism 24. The front Y-axis driving mechanism 22 adjusts the front backing mold 25, the front X-axis driving mechanism 24, the front cutting motor 26 and the front saw blade 27 in the Y-axis direction, and the front X-axis driving mechanism 24 adjusts the front cutting motor 26 and the front saw blade 27 in the X-axis direction.

[0034] The rear cutting device 30 includes a rear slider 37, a rear support plate 31 mounted on the rear slider 37, a rear X-axis driving mechanism 32 and a rear backing mold 34 mounted on the rear support plate 31, a rear cutting motor 33 mounted on the rear X-axis driving mechanism 32, a rear saw blade 36 mounted on the rear cutting motor 33, and a backing wheel 35 mounted at the bottom of the rear backing mold 34, wherein the backing wheel 35 is rotatably mounted on the rear backing mold 34, and the outer periphery of the backing wheel 35 extends below the backing mold, and the rear positioning device 50 is connected to the rear support plate 31, and the rear slider 37 is slidably mounted on the main guide rail 60. Through the rear slider 37 mounted on the main guide rail 60, the rear positioning device 50 drives the entire rear cutting device 30 to be adjusted along the extension direction on the main guide rail 60. In this embodiment, the rear positioning device 50 is a cylinder, and the rear positioning device 50 and the front positioning device 40 are arranged in opposite directions. The rear end of the cylinder body 51 of the rear positioning device 50 is movably mounted on the head frame 10 , and the front end of the piston rod 52 of the rear positioning device 50 is movably mounted on the rear support plate 31 .

[0035] Among them, the rear X-axis driving mechanism 32 adopts the cooperation mode of the guide rail 321 and the slider 322, and adopts the cylinder 323 to drive the slider to move, wherein the rear cutting motor 33 is installed on the slider 322 of the rear X-axis driving mechanism 32, and the rear X-axis driving mechanism 32 adjusts the rear cutting motor 33 and the rear saw blade 36 in the X-axis direction.

[0036] The working process of the head-to-tail cutting device of the present invention is described in detail below:

[0037] Initially, the front positioning device 40 and the rear positioning device 50 respectively drive the front cutting device 20 and the rear cutting device 30 to adjust before cutting, so that the bottom of the wheel 35 of the rear cutting device 30 is located on the path of the plate 100 being delivered forward, the rear saw blade 36 is located above the moving path of the edge banding strip 200, the front mold 25 of the front cutting device 20 is located on the path of the plate 100 being delivered forward, and the front Y-axis driving mechanism 22 drives the front saw blade 27 to extend above the moving path of the edge banding strip 200. The rear positioning device 50 supports the rear cutting device 30 in the upward and backward direction, and the front positioning device 40 pulls the front cutting device 20 in the upward and backward direction. The front X-axis drive mechanism 24 drives the front saw blade 27 to be fine-tuned forward so that the cutting plane of the front saw blade 27 moves to 1 mm in front of the front side surface of the front backing 25, and the rear X-axis drive mechanism 32 drives the rear saw blade 36 to be fine-tuned backward so that the cutting plane of the rear saw blade 36 moves to 1 mm behind the rear side surface of the rear backing 34. By fine-tuning the front saw blade 27 forward and the rear saw blade 27 backward, vibration of the plate 100 during the cutting process can be effectively prevented, thereby causing the phenomenon of cutting the effective part of the edge strip.

[0038] When performing tail cutting, the plate 100 enters the finger-in position and is detected by the sensor. When the plate 100 moves further forward, the rear adjusting device 50 releases the rear cutting device 30, and the plate 100 rests on the supporting wheel 35. Under the guidance of the supporting wheel 35, the rear cutting device 30 is pushed backward and upward along the main guide rail 60 to adjust its position. When the plate 100 continues to be fed forward, the supporting wheel 35 rolls on the upper end surface of the plate 100 until the supporting wheel 35 rolls out from the tail end of the plate 100. Since the rear cutting device 30 lacks upward supporting force, under the action of gravity, the rear cutting device 30 moves forward and downward rapidly along the main guide rail 60, and the front side surface of the rear support mold 34 is in contact with the rear side surface of the plate 100. During the downward pressing process along the main guide rail 60, the rear cutting motor 33 drives the rear saw blade 36 to cut the tail end of the edge banding strip 200.

[0039] When performing the head cut, as the plate 100 continues to feed forward, the plate 100 fits against the rear side of the front support mold 25, and the plate 100 cooperates with the front positioning device 40. At this time, the front chamber of the front positioning device 40 is in a pressure relief state, and the forward speed of the front cutting device 20 under the limit of the piston rod 42 is less than the advancing plate 100. The piston rod 42 of the front cutting device 20 moves forward and downward. While the advancing plate 100 fits against the rear side of the front support mold 25, the front cutting device 20 and the saw blade on the front cutting device 20 are driven to move forward and downward along the main guide rail 60. During the forward and downward movement of the front saw blade 27, the front cutting motor 26 drives the front saw blade 27 to cut the front end of the edge banding strip 200. After the cutting is completed, during the forward movement of the plate 100 and the front cutting device 20, the front Y-axis drive mechanism 22 drives the front saw blade 27 to withdraw from the moving path of the edge banding strip 200 to prevent the edge banding strip 200 on the plate 100 from colliding with the front saw blade 27. During the process of the front back film moving forward and downward, until the front back film moves to the bottom of the plate 100, the front mold 25 releases the restriction on the plate 100.

[0040] The beneficial effect of the head-to-tail cutting device of the present invention is that by respectively setting a front X-axis driving mechanism 24 and a rear X-axis driving mechanism 32 on the front cutting device 20 and the rear cutting device 30, during cutting, the front X-axis driving mechanism 24 drives the front saw blade 27 to make a fine adjustment forward, and the rear X-axis driving mechanism 32 drives the rear saw blade 36 to make a fine adjustment backward, which effectively prevents the plate 100 from vibrating during the cutting process, thereby causing the effective part of the edge strip to be cut, and at the same time ensures that the subsequent tracking and profiling edge banding is more beautiful. In addition, a front Y-axis driving mechanism 22 is further set on the front cutting device 20. After the cutting is completed, the front Y-axis driving mechanism 22 drives the front saw blade 27 to withdraw from the moving path of the edge banding strip 200, effectively preventing the phenomenon of hitting the plate.

[0041] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0042] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
