Description

The other ends of the two dust extraction pipes 25 are connected to an external dust collector. The dust extraction ends of the two bent dust extraction pipes 24 are respectively located above the two cloth dust removal brushes 23. The added left cloth dust removal brush 23 rotates counterclockwise, and the right cloth dust removal brush 23 rotates clockwise, which can clean the dust on the left and right end surfaces of the conveyed cloth, and the external dust collector can remove the dust swept from the upper end of the cloth dust removal brush 23 through the dust extraction pipe 25 and the bent dust extraction pipe 24, thereby making the cloth cleaner.

[0025] In the dual-drive mechanism 3, the right end of the motor 31 is connected to the frequency converter 30, and cam sensors and proximity switch controls are installed on the left and right sides of the cloth table 11. The frequency converter 30, the cam sensor and the proximity switch control are bidirectionally electrically connected through wires. First, the operating frequencies of the motor 31 in each stage (i.e., the frequency of the linear operation of the head 46 and the buffer operation frequency of the head 46 when reversing) are set on the frequency converter 30. Then, according to factors such as the softness and elasticity of the fabric, the stacking parameters such as the servo feed amount and the reversing feed compensation amount of the head 46 are set on the touch screen of the frequency converter 30. After the settings are completed, the cloth stacking function can be started. The added cam sensor and proximity switch (not shown in the figure) can provide timely feedback to the frequency converter 30 when the head 46 moves left or right in the cloth table 11. The installation has high reliability and low vibration and noise.

[0026] The two first gears 36 are respectively fixed to the front and rear ends of the transmission shaft 35, the two second gears 37 are respectively engaged with the two first gears 36 for transmission, the two connecting rods 38 are respectively movably connected to the upper ends of the relatively outer sides of the two second gears 37, and the two third gears 40 are respectively movably connected to the other ends of the two connecting rods 38.

By adding the two connecting rods 38 and the two third gears 40, when the two second gears 37 rotate, they can drive the two fourth gears 41 to swing and rotate in both directions.

[0027] The two fourth gears 41 are symmetrically mounted on the upper left of the front and rear ends of the wall panel 1, and the two fourth gears 41 are respectively meshed with the tooth ends of the two third gears 40. The two driving sprockets 42 are respectively located at the front and rear ends of the upper left of the interior of the wall panel 1, and are respectively connected to the two fourth gears 41. The two driven sprockets 45 are respectively installed with driven sprocket chain tensioners 44 on the relative outsides, and the two driven sprocket chain tensioners 44 are respectively installed at the front and rear ends of the upper right of the interior of the wall panel 1, and the two driven sprockets 45 are respectively connected to the two driving The sprockets 42 are connected to each other through chains 43. The machine head 46 is movably located at the upper end of the wall panel 1, and a moving wheel 53 is installed at the lower end of the machine head 46. The moving wheel 53 is slidably located at the front and rear sides of the upper end of the cloth table 11. The upper ends of the two chains 43 are respectively connected to the front and rear sides of the left and right ends of the machine head 46. Through the added chain 43, when the active sprocket 42 rotates, the driven sprocket 45 can be driven to rotate accordingly, so that the chain 43 can pull the machine head 46 to perform reciprocating motion in the left and right directions on the cloth table 11.

[0028] Net curtain receiving and sending rollers 54 are installed on both sides of the lower end of the machine head 46, and cloth feed rollers 51 and cloth passing rollers 52 are movably installed on the left and right ends of the middle of the machine head 46. The front end of the cloth feed roller 51 is connected to the servo motor 47 through a reducer, and the servo motor 47 is electrically connected to the servo drive data processor 48 through a wire. The rear ends of the cloth feed roller 51 and the cloth passing roller 52 are respectively provided with a fifth gear 49 and a sixth gear 50, and the fifth gear 49 is meshed with the sixth gear 50. By adding the fifth gear 49 and the sixth gear 50, when the servo motor 47 drives the cloth feed roller 51 to rotate, the cloth passing roller 52 rotates in the opposite direction.

[0029] As an embodiment of the present invention: when the cloth needs to be led to the machine head 46 for the cloth stacking operation, the cloth is first passed through the dust extraction frame 21, and then the two small motors 22 are started. The two small motors 22 can drive the two cloth dust removal brushes 23 to rotate in opposite directions, thereby enabling the two cloth dust removal brushes 23 to clean the dust on the left and right end surfaces of the cloth (see the side view). Figure 5 During this process, the left cloth dust removal brush 23 is driven to rotate counterclockwise, and the right cloth dust removal brush 23 is driven to rotate clockwise). At the same time, the external dust extractor is started, and the external dust extractor can remove the dust swept from the upper end of the cloth dust removal brush 23 through the dust extraction pipe 25 and the bent dust extraction pipe 24, thereby making the cloth cleaner.

[0030] As an embodiment of the present invention: when the cloth is led from the dust extraction frame 21 to the machine head 46, the cloth is passed through the cloth feed roller 51, the cloth passing roller 52 and the two mesh curtain receiving and sending rollers 54, and finally falls on the cloth table 11. Then, the power is turned on to each part of the device. First, the operating frequency of each stage of the motor 31 (i.e., the frequency of the linear operation of the machine head 46 and the buffer operation frequency of the machine head 46 when reversing) is set on the inverter 30. Then, according to factors such as the softness of the cloth and the size of the elasticity, the servo cloth feeding amount, the compensation amount of the reversing cloth feeding of the machine head 46 and other stacking parameters are set on the touch screen of the inverter 30. After the setting is completed, the cloth coding function can be started. When the motor 31 is powered on (refer to Figure 3 ), the motor shaft drives the motor pulley 32 to rotate, and at the same time drives the pulley 34 to rotate through the belt 33, and the pulley 34 drives the transmission shaft 35 to rotate, thereby driving the two first gears 36 to rotate (refer to Figure 2), and the second gear 37 meshing with the two first gears 36 will rotate in the opposite direction, and the two second gears 37 rotating in the opposite direction will drive the connecting rod 38 to swing the arm in a cycle, and the two connecting rods 38 of the circulating swing arm will drive the two third gears 40 to swing back and forth, thereby making the two fourth gears 41 mesh and rotate, thereby driving the two driving sprockets 42 to rotate, and the two driving sprockets 42 will drive the two driven sprockets 45 to rotate through the chain 43 (at this time, the two driven sprocket chain tensioners 44 are respectively installed at the front and rear ends on the upper right side of the wall panel 1, and the tension between the two driven sprockets 45, the two chains 43 and the two driving sprockets 42 is adjusted at the same time). When the two chains 43 are driven to rotate in the forward and reverse directions, they will pull the machine head 46 to perform a reciprocating linear motion in the left and right directions on the cloth table 11 to form a cloth coding trajectory (reference Figure 4 and Figure 1 During this process, the cam sensor and the proximity switch can provide timely feedback to the frequency converter 30 when the machine head 46 moves left or right in the cloth table 11, and the two mesh curtain receiving and sending rollers 54 then perform a reciprocating mesh curtain rewinding operation. This is an existing mature technology and will not be described in detail). At the same time, the servo motor 47 is started (the data signal is set in advance in the servo drive data processor 48 for cloth feeding operation). The servo motor 47 can drive the cloth feeding roller 51 and the fifth gear 49 to rotate in the same direction through the reducer, and the sixth gear 50 engaged with it will rotate in the opposite direction, and will drive the cloth feeding roller 52 to rotate in the opposite direction, thereby making the cloth passing through the machine head 46 for better transportation and cloth stacking effect, and more stable.
