Description

Technical Field

[0001] The invention relates to the technical field of sound insulation carpet processing, in particular to a sound insulation carpet water cutting device and a cutting method thereof. Background Art

[0002] Car sound insulation carpet is an important interior part of the car, which has both practical and decorative functions. It plays an important role in the acoustic sound insulation performance of the whole vehicle. As people's requirements for car quality continue to increase, the impact of car interior on consumers is also increasing. In the process of processing car sound insulation carpet, after the sound insulation carpet is formed, the sound insulation carpet is generally cut, generally through two cutting steps: water cutting and die cutting.

[0003] In the prior art, in the process of water cutting the car sound insulation carpet, the water cutting drilling operation is generally performed on the car sound insulation carpet by controlling the movement of the water cutting nozzle by a robot. Since the sound insulation carpet is usually composed of a multi-layer structure and contains velvet and cotton components, during the water cutting process, it is generally difficult for the water flow to cut the waste at the punching position from the whole sound insulation carpet. The waste generated by the punching will be hung on the sound insulation carpet through the connection between the velvet and cotton, affecting the subsequent processing of the sound insulation carpet. At the same time, affected by the material of the sound insulation carpet, velvet and cotton burrs will generally appear on the edges of the cutting punching position, affecting the processing quality of the sound insulation carpet.

After the sound insulation carpet is cut, the blade 8 at the bottom end of the first mounting rod 6 is controlled to move to the bottom of the water cutting nozzle 4, and the blade 8 passes through the bottom of the sound insulation carpet and fits the lower surface of the sound insulation carpet, and then the blade 8 is controlled to rotate, and the blade 8 is controlled by the robot to move along the cutting trajectory to cut off the connection between the cutting position of the sound insulation carpet and the cut waste material to prevent the cut waste material from being connected to the sound insulation carpet, thereby improving the water cutting effect of the sound insulation carpet. After the waste material on the water cutting trajectory of the sound insulation carpet is cut off, the grinding wheel 9 at the bottom end of the second mounting rod 7 is controlled to move to the cutting line of the water cutting nozzle 4, and then the blade 8 is controlled to rotate, and the grinding wheel 9 is controlled by the robot to move along the cutting trajectory to grind the cutting position of the sound insulation carpet, thereby improving the water cutting processing quality of the sound insulation carpet.

[0019] like Figures 1 to 5 As shown, a rotating drum 10 is symmetrically rotatably mounted on both ends of the first fixed plate 5 through bearings, the first mounting rod 6 and the second mounting rod 7 are both slidably mounted inside the corresponding rotating drum 10, a driven pulley 11 is fixedly mounted on the top of the rotating drum 10, a transmission belt 12 is installed between the two driven pulleys 11, a motor 13 is fixedly mounted on the bottom of one end of the first fixed plate 5, a driving wheel 14 is fixedly mounted on the output end of the motor 13 through the first fixed plate 5, the driving wheel 14 is transmission-connected to the transmission belt 12, and the output end of the motor 13 is rotationally connected to the first fixed plate 5.

[0020] The motor 13 drives the driving wheel 14 to rotate, and the transmission between the driving wheel 14 and the transmission belt 12 and the transmission between the two driven pulleys 11 by the transmission belt 12 will drive the rotating drum 10 to rotate, and will drive the first mounting rod 6 and the second mounting rod 7 to rotate synchronously, so as to control the rotation of the blade 8 and the grinding wheel 9.

[0022] In the process of controlling the rotation of the rotating drum 10, the positioning of the positioning slider 16 through the positioning groove 15 will drive the second transmission rod 21 and the second mounting rod 7 to rotate synchronously. At the same time, when the first mounting rod 6 or the second mounting rod 7 is lifted or lowered, the positioning slider 16 on the first mounting rod 6 and the second mounting rod 7 will continue to be inside the positioning groove 15 in the middle of the rotating drum 10 and the driven pulley 11. After the first mounting rod 6 or the second mounting rod 7 is lifted or lowered, the second transmission rod 21 and the second mounting rod 7 can be driven to rotate synchronously during the rotation of the rotating drum 10.

[0023] like Figures 1 to 5 As shown, a movable frame 17 is slidably installed on the top of the mounting plate 1, and a first connecting rod 18 and a second connecting rod 19 are rotatably installed on the bottom of both ends of the movable frame 17 through an axle pin, and a first transmission rod 20 and a second transmission rod 21 are rotatably installed on the top of the first mounting rod 6 and the second mounting rod 7 through bearings, respectively.

[0024] By driving the movable frame 17 to move left and right, the first connecting rod 18 connects the movable frame 17 and the first transmission rod 20, which will drive the first mounting rod 6 to slide and rise inside the rotating drum 10 to control the lifting and lowering of the blade 8. The second connecting rod 19 connects the movable frame 17 and the second transmission rod 21 to drive the second mounting rod 7 to slide and rise inside the rotating drum 10 to control the lifting and lowering of the grinding wheel 9.

[0025] like Figures 1 to 5 As shown, a limit rod 22 is symmetrically fixedly installed on the top of the mounting plate 1, and limit holes 23 are symmetrically opened on both sides of the movable frame 17.

[0030] When the first mounting rod 6 or the second mounting rod 7 is lifted or lowered, the return spring 27 will be in a compressed or stretched state. When the first mounting rod 6 or the second mounting rod 7 is reset or moved in the opposite direction, the return spring 27 pulls or pushes the first mounting rod 6 or the second mounting rod 7 to assist the first mounting rod 6 or the second mounting rod 7 in moving.

The second connecting rod 19 connects the mobile frame 17 with the second transmission rod 21 to drive the second mounting rod 7 to slide down inside the rotating drum 10 to control the grinding wheel 9 to descend. By moving the grinding wheel 9 at the bottom end of the second mounting rod 7 to the cutting line of the water cutting nozzle 4, the motor 13 drives the driving wheel 14 to rotate, and the driving wheel 14 is driven by the transmission belt 12 and the transmission belt 13. The transmission between the two driven pulleys 11 by the belt 12 will drive the rotating drum 10 to rotate.
