Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of blanking equipment more particularly to a precise action cloth rolling roller blanking device. BACKGROUND

[0002] In the textile operation process, after the knitting machine weaves cloth, the cloth must be pulled to a cloth rolling machine, and the cloth rolling machine is used to roll the cloth onto a cloth rolling roller. After the cloth rolling is completed, the cloth rolling roller is taken out. However, the existing cloth rolling machine needs manual opening of the baffle to roll the cloth onto the cloth rail when the cloth rolling roller is full. Moreover, the cloth rolling roller after the cloth rolling is completed is not light in weight. On the one hand, it is difficult for the baffle after long-term work to effectively block the cloth rolling roller after the cloth rolling is completed. On the other hand, manually opening and closing the baffle has certain safety hazards to the personal safety of personnel, and the cloth rolling process is too time-consuming and laborious.

[0003] Chinese patent CN201922044708.8 discloses a cloth pushing device with limiting function. The patent is to drive the baffle 601 to swing to push out the cloth rolling roller by the first cylinder body 604. The first cylinder body 604 adopts a gas pressure or hydraulic structure. In order to push out the cloth rolling roller, one first cylinder body 604 is arranged on each side of the cloth rolling roller. Although the patent does not specifically state this, it is common sense that even if the patent does not state the number of first cylinder bodies, the utility model is aimed at the case of two cylinder bodies. Due to factors such as equipment and site, the length of the two pipelines from the air pump or hydraulic pump to the first cylinder body 604 will have a deviation, and the time when the oil or gas reaches the cylinder body will have an error, resulting in that the two first cylinder bodies 604 cannot synchronously drive the baffle 601 to swing. The greater the pipeline length deviation is, the worse the synchronization accuracy is. Therefore, it is urgently needed to be improved. UTILITY MODEL CONTENTS

[0004] The utility model aims at: in order to solve the above technical problem, the utility model provides a precise action cloth rolling roller blanking device.

[0005] The utility model discloses a precise action cloth rolling roller blanking device to realize the above-mentioned purpose specifically adopts the following technical scheme:

[0006] A precise action cloth rolling roller blanking device, comprising a rack, lower rails are fixedly installed on both sides of the rack, an upper rail is arranged at the top of the lower rail, the upper rail is rotatably connected with the rack at the top, a servo motor is fixedly installed on the rack, a swing assembly is arranged between the servo motor and the upper rail, and the servo motor swings the upper rail through the swing assembly.

[0007] The swing assembly comprises a connecting plate and a connecting rod, the connecting plate is connected with the output shaft of the servo motor at the top, and the connecting rod is rotatably connected with the upper rail at one end and rotatably connected with the connecting plate at the other end.

[0008] A guide roller groove is provided above the upper rail. One end of the guide roller groove is connected to the top of the upper rail, and the other end is used to insert the fabric roll roller. The guide roller groove is fixedly installed on the frame. A through groove is opened at the bottom of the guide roller groove. An L-shaped limit rod is fixedly installed on the side wall of the upper rail. The top of the L-shaped limit rod inserts into or leaves the through groove as the upper rail swings, which acts as a limit switch for the fabric roll roller.

[0009] The guide roller groove is inclined downward at one end near the upper rail, with an inclination angle of 18-20°. The inclined design of the guide roller groove can prevent the fabric roll from falling out from behind the guide roller groove. In addition, the inclination angle of 18-20° can ensure that the fabric roll automatically slides down under its own weight while preventing it from sliding out of the groove at too fast a speed.

[0010] The length of the through groove is half the outer diameter of the fabric rolling roller.

[0011] The purpose of the guide roller groove is to store more spare fabric rolls at once, thereby improving work efficiency.

[0012] Working principle: Multiple fabric rolling rollers are placed in the guide roller groove for standby. The top of the L-shaped limit rod is inserted into the through groove to limit the fabric rolling roller. During operation, the servo motor drives the upper rail to swing, causing the top of the L-shaped limit rod to leave the through groove. The L-shaped limit rod at the front slides into the through groove. When the L-shaped limit rod moves back towards the servo motor to swing, the top of the L-shaped limit rod inserts into the through groove, pushing the fabric rolling roller open. The fabric rolling roller leaves the through groove, slides onto the upper rail, and then enters the lower rail. The fabric rolling machine starts to roll the fabric. After the fabric on the roll is finished, the roller shaft of the roll will rise to the upper rail. Then, repeat the above operation. When the servo motor works, it drives the upper rail away from the servo motor to swing and push out the rolled fabric roller. When the upper rail is close to the servo motor to swing, the empty rolled fabric roller is put into the lower rail through the L-shaped limit switch. The servo motor is electrically controlled, so there is no control time error or the error is negligible. Moreover, the servo motor itself has high control accuracy and position accuracy. Therefore, the servo motor setting can achieve precise pushing action. In addition, the setting of L-shaped limit rod and guide roller groove can realize automatic sliding of the rolled fabric roller, improving work efficiency.

[0013] The beneficial effects of this utility model are as follows:

[0014] The servo motor of this invention is electrically controlled, so there is no control time error or the error is negligible. Moreover, the servo motor itself has high control accuracy and position accuracy. Therefore, the servo motor can achieve precise material pushing action. In addition, the L-shaped limit rod and guide roller groove can realize the automatic sliding of the fabric roll roller, improving work efficiency. Attached Figure Description
