TECHNICAL FIELD

[0001] The application relates to processing equipment, in particular to a belt type up-down knife numerical control cutting machine. BACKGROUND

[0002] In the past two years, the rise of rock plate market has brought challenges to cutting equipment. The original ceramic numerical control cutting machine has an unsatisfactory and unstable effect when cutting rock plates. The cutting speed is reduced by more than 50%, and the problems of bottom falling and corner collapse are more prominent. SUMMARY

[0003] The application aims to provide a cutting machine capable of avoiding corner collapse of a plate during cutting.

[0004] A belt type up-down knife numerical control cutting machine comprises a main frame, a transmission mechanism, a pressing mechanism, a width adjusting mechanism and a cutting mechanism. The transmission mechanism is arranged on the main frame and used for moving a plate. The width adjusting mechanism is arranged on the main frame and used for righting the plate during the plate transportation by the transmission mechanism. The pressing mechanism is arranged on the main frame and used for pressing and fixing the plate when the plate needs to be cut. The cutting mechanism is arranged on the transmission mechanism and comprises sectional cutting units used for distributed cutting of the plate.

[0005] Preferably, the cutting unit comprises a first upper knife assembly, a lower knife assembly and a second upper knife assembly. The first upper knife assembly, the lower knife assembly and the second upper knife assembly are respectively provided with a first upper knife, a lower knife and a second upper knife. The first upper knife and the second upper knife are sequentially arranged above the transmission mechanism, and the lower knife is arranged between the first upper knife and the second upper knife and below the transmission mechanism. The first upper knife, the lower knife and the second upper knife are all arranged on the same plane and parallel to the advancing direction of the transmission mechanism.

[0006] By using the above mechanism, the plate is driven by the transmission mechanism and sequentially passes through the first upper knife assembly, the lower knife assembly and the second lower knife assembly. When the plate passes through, the first upper knife is first fed by one third of the thickness of the plate to cut the upper part of the plate, then the lower knife is fed by one third of the thickness of the plate to cut the lower part of the plate, and finally the second upper knife cuts the remaining connecting part. The plate is cut by multiple distribution to prevent the edge of the plate from being cracked due to sudden excessive cutting force, thereby greatly improving the quality of plate processing.

[0007] Preferably, the cutting mechanism comprises a first lifting assembly, a second lifting assembly and a third lifting assembly; the first upper blade is installed below the first lifting assembly; the second upper blade is installed below the second lifting assembly; the lower blade is installed above the third lifting assembly; the first lifting assembly, the second lifting assembly and the third lifting assembly are all installed on the transmission mechanism.

[0008] With the above mechanism, when the plate passes through the cutting mechanism, the first lifting assembly, the second lifting assembly and the third lifting assembly control the lifting of the first upper blade, the second upper blade and the lower blade, and immediately retract inward after the current blade finishes cutting the plate, avoiding interference with subsequent cutting during the cutting process.

[0009] Preferably, the pressing mechanism comprises a fixed frame, a rolling wheel and a lifting platform; the two ends of the fixed frame are provided with lifting platforms, and the lifting platforms are fixedly connected with the main frame; a plurality of rolling wheels are installed on the fixed frame, and the rolling wheels are equidistantly arranged along the running direction of the transmission mechanism.

[0010] With the above mechanism, during the cutting of the plate, the plate will shake due to the cutting force, affecting the cutting accuracy, and the plate is pressed by the plurality of rolling wheels to ensure the normal passage of the plate.

[0011] Preferably, the lifting platform comprises a lifting cylinder and a handle; the lifting cylinder is installed on the connecting piece, and the handle is installed at the end of the lifting cylinder for adjusting the stroke of the lifting cylinder.

[0012] With the above mechanism, when the plate is pressed, if the pressure is too large, the plate cannot move normally, and if the pressure is too small, the plate cannot be pressed, and the stroke of the lifting cylinder is adjusted by rotating the handle, so as to adjust the pressure of the pressing mechanism.

[0013] Preferably, the width adjusting mechanism comprises a position adjusting plate, a connecting block and a position adjusting assembly; the position adjusting plate is placed above the transmission mechanism and parallel to the running direction of the transmission mechanism, two position adjusting assemblies are connected at both ends of the position adjusting plate through the connecting block, and the position adjusting assembly can push the position adjusting plate to reciprocate.

[0014] With the above mechanism, when the plate enters the transmission mechanism, the position of the plate may be offset, and the position adjusting assembly pushes the position adjusting plate to contact and press the plate, so as to adjust the position of the plate, making the cutting more accurate.

[0015] Preferably, the transmission mechanism comprises a first conveyor belt and a second conveyor belt; the first conveyor belt and the second conveyor belt are arranged in parallel between the first conveyor belt and the second conveyor belt, gaps are arranged in the first conveyor belt and the second conveyor belt, and the cutting unit is arranged in the gaps.

[0016] With the above mechanism, the lower blade is lifted or lowered from the gap between the first conveyor belt and the second conveyor belt during the cutting of the plate, so that interference between the transmission mechanism is avoided.

[0017] Preferably, the supporting mechanism is arranged, and a plurality of groups of the supporting mechanism are arranged on both sides of the transmission mechanism and are parallel to the running direction of the transmission mechanism. A plurality of groups of supporting wheels are arranged on the supporting mechanism.

[0018] With the above mechanism, the width of the plate is greater than the width of the transmission mechanism, and the protruding part of the plate is supported by the supporting mechanism to prevent the plate from shaking during processing, thereby improving the stability during processing.

[0019] Beneficial effects: The plate is segmented and cut by the cutting mechanism, so that the plate is prevented from being broken due to excessive impact. In the processing process, the positioning of the width adjusting mechanism and the pressing mechanism is used to prevent the plate from shaking, thereby improving the stability of the processing, and finally improving the quality of the processed plate.

[0030] Firstly, when the plate enters the transmission mechanism 2, the position of the plate may be offset, the position adjusting assembly 52 pushes the position adjusting plate 50 to contact and press the plate, so as to adjust the position of the plate, and the cutting is more accurate.

[0031] Then, the plate is driven by the transmission mechanism 2, and sequentially passes through the first upper knife assembly, the lower knife assembly and the second lower knife assembly, when the plate passes, firstly, the feeding amount of the first upper blade 40 is one third of the thickness of the plate, the upper part of the plate is cut, then the feeding amount of the lower blade 42 is one third of the thickness of the plate, the lower part of the plate is cut, finally the remaining connecting part is cut by the second upper blade 41, the plate is cut by multiple distribution, the edge of the plate is prevented from being broken due to sudden excessive cutting force, and the quality of the plate processing is greatly improved.
