Thus, features defined with "first", "second", etc. may explicitly or implicitly include one or more of such features. In the description of the present application, unless otherwise specified, the meaning of "a plurality" is two or more.

[0019] In the present application, unless otherwise clearly specified and defined, the term "connection" shall be understood in a broad sense. For example, "connection" may be a fixed connection, a detachable connection, or integrated; it may be directly connected or indirectly connected through an intermediate medium.

[0020] The embodiment of the present application provides a non-chip cross-cutting machine, which is arranged on a board production line and is used to cut the boards on the board production line. In the embodiment of the present application, the board production line conveys the boards from front to back, and the non-chip cross-cutting machine cross-cuts the conveyed boards on the board production line in the left-right direction.

[0021] As Figure 1 shown, the non-chip cross-cutting machine 100 includes: a longitudinal movement mechanism 10, a transverse movement mechanism 20 arranged on the longitudinal movement mechanism 10, and a cutting tool mechanism 30 arranged on the transverse movement mechanism 20.

[0022] As Figures 1-4As shown in the figure, the longitudinal movement mechanism 10 includes a frame 1 that can move back and forth in the front-rear direction and a first drive assembly 2 that drives the frame 1 to move in the front-rear direction. A conveying channel 101 for the sheet material to pass through is provided on the frame 1; the first drive assembly 2 includes a longitudinal rack 21 extending in the front-rear direction, a longitudinal movement gear 22 with its axis extending in the left-right direction, and a longitudinal movement motor 23 that drives the longitudinal movement gear 22 to rotate. The longitudinal movement gear 22 meshes with the longitudinal rack 21, and the longitudinal movement motor 23 is fixedly connected to the frame 1. When the longitudinal movement motor 23 drives the longitudinal movement gear 22 to rotate, the tooth surface of the longitudinal rack 21 pushes the engaged longitudinal movement gear 22 to move along the longitudinal rack 21. At the same time, the longitudinal movement motor 23 coaxially arranged with the longitudinal movement gear 22 drives the frame 1 to move in the front-rear direction.

[0023] The longitudinal movement mechanism 10 further includes a base 3 supported on the ground. A guide rod 301 extending in the front-rear direction is provided on the base 3. The bottom of the frame 1 has a slider 102 that cooperates with the guide rod 301. The slider 102 is configured to be able to move back and forth along the guide rod 301. When the first drive assembly 2 drives the frame 1 to move along the longitudinal rack 21, the cooperation between the guide rod 301 and the slider 102 provides guidance for the movement of the frame 1 and prevents the frame 1 from shifting left and right during the movement.

[0024] The front end and the rear end of the frame 1 are provided with brackets 103 for supporting and allowing the sheet material to move. The brackets 103 both extend in the front-rear direction and are both located below the conveying channel 101. A number of conveying rollers 104 are provided on the brackets 103, and the axis of each conveying roller 104 extends in the left-right direction.

[0025] As Figure 1 、 2 shown, the transverse movement mechanism 20 is located above the conveying channel 101. As Figure 5 、 7 shown, the transverse movement mechanism 20 includes a sliding seat 4 that can move back and forth in the left-right direction and a second drive assembly 5 that drives the sliding seat 4 to move back and forth in the left-right direction; as Figure 7 、 9 shown, the second drive assembly 5 includes a transverse rack 51 extending in the left-right direction, a transverse movement gear 52 with its axis extending in the front-rear direction, and a transverse movement motor 53 that drives the transverse movement gear 52 to rotate. The transverse movement gear 52 meshes with the transverse rack 51, and the transmission shaft of the transverse movement motor 53 coaxially penetrates the transverse movement gear 52. The transverse movement motor 53 is fixedly arranged on the sliding seat 4. When the transverse movement motor 53 drives the transverse movement gear 52 to rotate around its own axis, the tooth surface of the transverse rack 51 pushes the engaged transverse movement gear 52 to move along the transverse rack 51. At the same time, the transverse movement motor 53 connected to the transverse movement gear 52 drives the sliding seat 4 to move in the left-right direction.

[0026] As Figure 5 、 7As shown in FIGS. 9, the transverse movement mechanism 20 further includes a cross beam 6 fixedly arranged on the frame 1 and a guiding assembly 7 arranged between the cross beam 6 and the sliding seat 4. The cross beam 6 extends in the left-right direction. The transverse rack 51 is fixedly connected to the cross beam 6, and the tooth surface of the transverse rack 51 faces upward. The transverse movement gear 52 meshes with the transverse rack 51 from above the transverse rack 51. The guiding assembly 7 includes at least one transverse movement guide rail 71 arranged on the cross beam 6 and at least one transverse movement slider 72 arranged on the sliding seat 4. One transverse movement guide rail 71 is slidably matched with at least one transverse movement slider 72. The sliding seat 4 is slidably connected to the cross beam 6 through the guiding assembly 7. When the transverse movement motor 53 drives the transverse movement gear 52 to rotate, the transverse movement slider 72 drives the sliding seat 4 to move back and forth along the corresponding transverse movement guide rail 71, realizing the transverse movement of the sliding seat 4.

[0027] As Figures 5-9 shown, the cutting tool mechanism 30 is arranged on the sliding seat 4. The cutting tool mechanism 30 includes a blade assembly 8 for cutting the plate and a cutting tool cylinder 9 for driving the blade assembly 8 to move back and forth in the up-down direction. When the non-chip cross-cutting machine 100 performs cutting, the cutting tool cylinder 9 lowers the blade assembly 8 to the conveying channel 101, so that when the blade assembly 8 moves along the cutting direction with the sliding seat 4, the plate in the conveying channel 101 is cut off.

[0028] The cutting tool mechanism 30 includes a lifting seat 11 for carrying the blade assembly 8. The lifting seat 11 is slidably connected to the sliding seat 4 and is configured to be able to move back and forth in the up-down direction relative to the sliding seat 4. The sliding seat 4 is provided with a lifting guide rail 12 extending in the up-down direction, and the lifting seat 11 is provided with a lifting slider 13 slidably matched with the lifting guide rail 12. The cylinder body of the cutting tool cylinder 9 is fixedly connected to the sliding seat 4, and the telescopic rod of the cutting tool cylinder 9 is fixedly connected to the lifting seat 11. When the telescopic rod of the cutting tool cylinder 9 extends and retracts from the cylinder body, the lifting slider 13 moves back and forth along the lifting guide rail 12, realizing the lifting of the lifting seat 11 driving the blade assembly 8. The cutting tool cylinder 9 can adjust the lowering height of the blade assembly 8 according to the thickness of the plate, so that the non-chip cross-cutting machine can be applicable to the cutting of plate products with different thicknesses.

[0029] As Figure 5 、 6As shown, the blade assembly 8 includes at least four blades 81. The at least four blades 81 are arranged in sequence in the left-right direction. The lower ends of the at least four blades are gradually inclined upward along the cutting direction of the cutting mechanism. In the embodiment of the present application, the cutting direction of the cutting mechanism 30 is from left to right. The sliding seat 4 drives the cutting mechanism 30 to traverse from left to right to cut the sheet material. Since the sheet material is relatively thick, the resistance to cutting is large, which makes the blade prone to breakage. To avoid blade breakage, the lower ends of the at least four blades 81 of the present application are gradually inclined upward from left to right. When cutting, the cutting depth gradually increases from right to left. The gradually increasing cutting depth is beneficial to the continuity of the cutting of the blade assembly 8 and effectively avoids blade breakage. Moreover, the present application uses blade cutting, which is dust-free and chip-free, ensuring a clean production environment.

[0030] As Figure 1 shown, a protective cover 14 and a length meter are further provided on the frame 1. The protective cover 14 surrounds the outside of the traversing mechanism and the cutting mechanism 30 for protection and sound insulation. The length meter is used to detect the length of the current sheet material, so that the dust-free cross-cutting machine 100 can cut the sheet material according to production requirements.

[0031] During the production process of the sheet material, when the length meter detects that the sheet material reaches a certain length, the cutting cylinder 9 lowers the blade assembly 8 to the conveying channel 101 according to the thickness of the sheet material. And the longitudinal movement motor 23 and the transverse movement motor 53 are started simultaneously. The longitudinal movement motor 23 drives the frame 1 to move from front to back at the same moving speed as the sheet production line. The transverse movement motor 53 moves from left to back, so that the blade assembly 8 cuts the sheet material with the cutting depth increasing in sequence. The cutting cylinder 9 raises the blade assembly 8 to reset. The transverse movement motor 53 resets the sliding seat 4 from right to left. The longitudinal movement motor 23 drives the frame 1 to move from back to front to return to the initial position. The dust-free cross-cutting machine 100 waits for the length meter to detect the next cutting position and then performs the above process to cut the sheet material.

[0032] The structure of the present application is simple. The transverse and longitudinal movements of the cutting tool assembly are realized through the meshing of gears and racks, which reduces costs, improves the running stability, and realizes dust-free and chip-free cutting, achieving dust-free production.

[0033] The above shows and describes the basic principles, main features and advantages of the present application. Those skilled in the art of this industry should understand that the present application is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present application. Without departing from the spirit and scope of the present application, the present application will have various changes and improvements.
