DETAILED DESCRIPTION

[0015] The specific technical solutions of the present invention are further described below. To make the purpose, technical solutions and advantages of the embodiments of the present invention clearer and to facilitate those skilled in the art to further understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in combination with the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them, and do not constitute a limitation on the rights thereof. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

[0016] It includes a frame component 1, a cleaning component 2, a cloth spreading component 3, a damping component 4, a front traction component 5, a rear traction component 6, a raising component 7, a cloth discharging component 8, a left box component 9, a right box component 10, a cloth tightening component 11 and a cloth spreading centering device 12, etc.

[0017] The raising component includes a raising cylinder and a raising roller mounted on the raising cylinder, and its characteristics are: A raising cylinder combined transmission mechanism is provided on one side of the frame component, and a raising roller transmission component is provided on the other side of the frame component; The combined transmission mechanism of the raising cylinder includes the main motor transmission component, the raising cylinder main shaft transmission component and the cleaning transmission component. The main motor transmission component includes a motor 21, a motor pulley, a large pulley of a transmission shaft, a motor plate, a vertical bearing seat, a transmission shaft 23, and a combined pulley. The motor plate is installed on the large surface of a wall panel 24 of the raising machine; the motor is installed on the motor plate; the motor pulley is installed on the shaft head of the motor; the transmission shaft is installed on the motor plate through a vertical bearing seat; a large pulley of the transmission shaft and a combined pulley are installed at both ends of the transmission shaft respectively; the cylinder transmission wheel on the transmission component of the raising cylinder main shaft is installed on the main shaft; the combined pulley is provided with a cylinder transmission wheel groove, the cylinder transmission wheel groove is connected to the cylinder transmission wheel through a transmission belt, and then the cylinder transmission wheel drives the main shaft 22 to rotate, and its rotation direction is set opposite to the cloth running direction; The raising roller transmission component includes a transmission large gear ring 26 coaxially arranged with the main shaft of the raising cylinder, the inner teeth of the transmission large gear ring mesh with the transmission shaft gear 25 at the end of the raising roller, and a driving motor for driving the large gear ring to rotate is installed on the wall plate 24 on the same side of the large gear ring. The driving motor drives the large gear ring to rotate and drives the raising roller to rotate in the same direction as the cloth feeding direction; The rotation direction of the cylinder and the raising roller are opposite to each other. By increasing the rotation speed of the large gear ring, the speed of the raising roller can be increased, thereby increasing the raising force. The cleaning transmission component comprises a cleaning roller and an air suction hood. The cleaning transmission component is arranged on a cleaning roller pulley at the end of the cleaning roller. The combined pulley is provided with a cleaning wheel groove. The cleaning wheel groove is connected to the cleaning roller pulley through a transmission belt. The cleaning roller pulley drives the cleaning roller and the raising roller to rotate in opposite directions.

[0018] The power transmission of the main motor transmission component is driven by the motor pulley, which transmits the power to the large pulley of the transmission shaft through the V-belt; then the large pulley of the transmission shaft drives the transmission shaft to the combined pulley. There are six pulley grooves on the combined pulley, and five pulley grooves on it transmit power to the cylinder drive wheel through five V-belts, and then the cylinder drive wheel drives the main shaft to rotate, and the cylinder main shaft completes the power transmission. The cleaning transmission component transmits power to the cleaning roller pulley through a single V-belt from another pulley groove on the combined pulley, and the cleaning roller pulley can drive the cleaning roller to rotate. The pulley on the cleaning tensioning component, the combined pulley and the cleaning roller pulley form a closed-loop transmission through the above-mentioned V-belt.

[0019] The cleaning roller 13 is driven by the main motor of the raising component 7. The cleaning roller 13 is arranged in the middle of the device, leaving enough space for the front and rear traction layout. The suction hood 14 is compact and simple in design, and one side of the baffle can be flipped movably to facilitate the cleaning of waste hair, and the entire hood is detachable.

[0020] The spreading component 3 is equipped with three spreading rollers with opposite rotation directions, which share a common motor drive. The spreading roller is a roller with two or three spreading wires wound from the middle to both sides. The density of the spreading wires on the spreading roller can be customized according to the needs of the cloth making process. The spreading component is equipped with a separate motor, combined with the V-belt and chain transmission, so that one motor drives three spreading rollers.

[0021] The damping component 4 uses a floating pneumatic damping transmission. The pneumatic clutch is installed on the large surface of the wall panel, and the inside is sleeved on the shaft head of the damping roller 15. A pneumatic hand-pull valve and a pressure gauge are separately configured. The resistance is controlled by air pressure, and the damping effect is outstanding.

[0022] The diameter of the traction rollers in the front traction component 5 and the rear traction component 6 is thickened, and the roller diameters are configured to be the same size. The front and rear traction distances are shortened, so that the wrap angle of the cloth on the cylinder increases and the raising efficiency increases. The front traction component 5 and the rear traction component 6 are each equipped with a reduction motor, and both use a frequency converter to control the reduction motor. Parameters such as tension, current, and torque are set on the screen, and the values ​​are visually adjustable. During operation, the parameters can be dynamically adjusted at any time according to the fabric process and other related parameters. The rear traction component 6 uses three traction rollers for transmission. The tension can be adjusted between the cylinder and the cloth outlet roller 18 to fully release the tension of the cloth on the traction roller, ensure sufficient raising, and increase efficiency.

[0023] The raising principle of the present invention is that the cylinder speed N1 is opposite to the large gear ring speed N2; the large gear ring speed N2 is in the same direction as the cloth running speed. If the raising force needs to be increased, N2 can be increased (to adjust the raising force).

[0024] According to the above design principle, in the raising component 7, the structure and transmission ratio of each part are optimized accordingly. The nylon gear 16 on the raising roller component increases the modulus and the tooth thickness, and the raising zero point will increase with the increase of the cloth speed during operation. After optimizing the transmission ratio, under the working condition of the cloth speed of 20 to 45 meters, the straight and curved needle inverters will have a very good frequency band, and the maximum cloth speed can reach 50 meters / minute. However, due to the small modulus and small diameter of the nylon gear on the raising roller component of the traditional variable frequency gear raising machine, the raising zero point will decrease with the increase of the cloth speed. When the cloth speed reaches 30 meters / minute, the speed of the large gear ring will quickly approach zero. Therefore, the raising cloth speed will be restricted by this.

[0025] The straight and curved needle raising rollers adopt different roller diameters, and the curved needles do not need to be padded with paper. In actual work, the work efficiency can be improved. The large gear ring external transmission of the straight and curved needles adopts a pneumatic wheel-type clutch device 17, and then through the coordination of the electrical program, it can automatically clutch according to the needs when the equipment is running. The use of the pneumatic wheel-type clutch device 17 changes the electromagnetic clutch transmission method used in the traditional variable frequency raising roller, and the structure is greatly simplified and reliable, the cost is reduced, and it is not afraid of hair clamping, and the clutch is smooth. The gear 20 on it is made of steel material, and the service life is correspondingly increased.

[0026] The cloth drop roller 18 and the cloth swing 19 in the cloth discharging component 8 are each equipped with a separate reduction motor. By reasonably configuring the speed ratio, the cloth drop and the cloth swing are synchronously driven through the inverter. The tension, current, torque and other parameters of the cloth drop roller 18 are also set on the screen. The right box assembly 10 of the equipment is equipped with front and rear double touch screens, so that the operator can see all the operating parameters and operating status of the equipment at the front and rear. According to the process requirements, the relevant information can be adjusted and viewed on the screen at any time, which is convenient for operation and conducive to efficient production.

[0027] The cloth tightening component 11 and the cloth spreading centering device 12 are optional parts of the equipment. They can help the fabric to have a good unfolding state and center in the middle of the equipment before entering the main machine. At the same time, by adjusting the appropriate tension, the fabric entering the main machine can match the set cloth making parameters to meet the cloth making requirements. At the same time, in order to improve production efficiency and increase equipment competitiveness, the equipment can also be equipped with an online automatic needle striking mechanism, which can automatically strike the needle on the equipment, shorten the work preparation time, and save time and safety compared to the traditional needle striking method. At the same time, during online production, an online control switch can also be installed to realize a one-button online start and stop function.
