Description

TECHNICAL FIELD

[0001] The present application relates to the field of toy manufacturing technology, in particular to a toy model cutting machine and a cutting method thereof. BACKGROUND

[0002] In the process of toy manufacturing, the outer clothing of many toys needs to use cloth, and the cutting machine as a processing tool of cloth can accurately and quickly cut the cloth according to the design pattern, improve the production efficiency and processing accuracy, and reduce material waste.

[0003] The cutting machine mainly includes a cutting tool, a conveying component and a control system. When the cloth needs to be cut, the cloth is first laid flat on the conveying component. Some cutting machines are also provided with a positioning mechanism. After the cloth is laid, the side edges of the cloth are pressed and positioned by the positioning mechanism to prevent wrinkles. The control system is used to control the cutting tool, such as the moving track, speed and depth of the tool, and then the cutting of the cloth is realized.

[0004] For the related technology in the above, in the processing process, the cut material still stays in the original position, and the operator needs to take the waste material from the conveying component after cutting, so that the cut material and the waste material are separated, and then the required cut material can be collected and picked up. Manual picking up cannot guarantee stable and efficient, which affects the cutting processing efficiency. SUMMARY

[0005] In order to improve the cutting processing efficiency, the present application provides a toy model cutting machine and a cutting method thereof.

[0006] In the first aspect, the present application provides a toy model cutting machine, which adopts the following technical scheme:

[0007] A toy model cutting machine, comprising a rack, the rack is provided with a conveying belt for conveying cloth, and the rack is provided with a cutting knife at the upper end for cutting cloth, the tail end of the rack along the conveying direction of the conveying belt is rotatably connected with a waste roller, the rack is further provided with a transfer drum, the transfer drum is located between the waste roller and the conveying belt, the rack is provided with two groups of supporting blocks along the width direction, the transfer drum is located between the two supporting blocks and is rotatably connected with the supporting blocks, the rack is provided with a driving piece for driving the transfer drum to rotate, the transfer drum is provided with a plurality of ventilation grooves along the axial direction, the plurality of ventilation grooves are uniformly arranged around the axis of the transfer drum, a plurality of ventilation holes are arranged on the outer side of the transfer drum along the circumferential direction, one ventilation hole corresponds to one ventilation groove in the same row, the ventilation hole is used to communicate the ventilation groove with the outside, the supporting block is provided with an air inlet and an air outlet, the air inlet and the air outlet are symmetrically arranged around the transfer drum, and the air inlet is located above the air outlet, when the transfer drum rotates, the ventilation groove is alternately communicated with the air inlet and the air outlet, and the supporting block is provided with an air suction piece, the air suction piece is used to convey the airflow in the air inlet to the air outlet.

[0008] By adopting the above technical scheme, after the cloth is laid on the conveying belt, the cloth is cut by the cutting knife from one end of the cloth close to the waste roller, and after cutting, the cloth is moved to the waste roller by the conveying belt during operation. After cutting, the cloth has continuous narrow edges on both sides in the width direction, and the narrow edges are wound and collected by the waste roller. The driving member drives the transfer drum to rotate, so that all the air grooves are alternately connected and disconnected with the suction port and the exhaust port. When the suction member works, the air pressure of the suction port decreases, and the air pressure of the exhaust port increases. For any air groove, when the air groove is located above the transfer drum, it is connected with the suction port, at this time the corresponding air hole is opposite to the cloth, at this time the transfer drum adsorbs the cloth under the action of low air pressure, in this process the waste roller collects the waste, when the upper end of the transfer drum rotates downward, the cutting material is separated from the waste under the adsorption of the through hole. When the air groove is connected with the exhaust port, the air pressure rises, and the adsorbed cutting material is separated from the transfer drum, and the cutting material falls naturally under the action of gravity, thereby completing the collection of the cutting material. The collection of the cutting material does not need manual assistance, which is beneficial to improve the cutting processing efficiency.

[0009] Optionally, the upper end of the rack is provided with a cross rack, which is located above the transfer drum and is arranged in parallel with the transfer drum.

[0010] By adopting the above technical scheme, the cross rack supports the soft plate through the sliding block, and the position of the soft plate can be adjusted when the sliding block moves along the cross rack. When cutting the cloth, the soft plate contacts the cloth under the action of gravity. When the soft plate contacts the cutting material, it pushes the cutting material away from the waste, which is beneficial to improve the separation effect of the cutting material and the waste.

When the pushing rods push the waste in the cutting material, the gas sending device sends gas flow into the cavity through the hose, the gas flow enters the exhaust holes one through the through holes and flows toward the waste through the exhaust holes two, the waste is separated from the cutting material by the gas flow, and the separation effect of the waste and the cutting material is improved.

When the cutting material has a hole structure, the waste port of the flat plate is arranged according to the shape of the hole structure, and when the cutting material is moved after cutting, the hole structure of the cutting material is opposite to the waste port, at this time the pushing cylinder drives the pushing rod to move downward, so that the pushing rod pushes the waste in the hole structure along the waste port into the vertical groove, so that the waste in the cutting material is separated from the cutting material, without subsequent processing, which is helpful to further improve the collection effect of the cutting material.
