[0002] Warp yarn refers to a string of yarn extending along the length of the loom, from which the yarn is spun into the lines of the fabric along the length. The warp frame is a device for mounting the warp roll, which is wound on the yarn reel, and the yarn reel is mounted on the yarn reel of the warp frame, so that the warp frame can provide the required number of warp yarns to the weaving machine.

[0011] Attached Figure 1 is a schematic diagram of the internal structure of the electrical cavity;

[0012] Attached Figure 2 is a schematic diagram of a motor array;

[0013] Attached Figure 3 It is a schematic diagram of the structure of the yarn reel. DETAILED DESCRIPTION

[0014] The utility model is further described below in conjunction with the accompanying drawings.

[0015] As attached Figures 1 to 3 The closed warp unwinding frame comprises an unwinding frame plate 1, a yarn reel 2 is installed on the front of the unwinding frame plate 1, and when working, the yarn reel disk wound with the warp roll is correspondingly installed on the yarn reel 2. An electrical chamber 3 is arranged on the back of the unwinding frame plate 1, and a motor 4 and a controller 5 are installed in the electrical chamber 3. The motor 4 drives the yarn reel 2 to rotate, and the controller 5 controls the motor 4. A transmission hole 10 is opened on the unwinding frame plate 1, and the motor 4 is installed on the back of the unwinding frame plate 1. The output shaft of the motor 4 extends from the transmission hole 10 to the front of the unwinding frame plate 1, and the yarn reel 2 is installed on the output shaft of the motor 4. The yarn reel disk wound with the warp roll is detachably installed on the yarn reel 2.

[0016] In one embodiment, the controller 5 is a PLC programmable controller 5, the motor 4 is a servo motor 4, and a driver 12 is installed next to the motor 4. The PLC programmable controller 5 controls the servo motor 4 through the driver 12, and controls the torque change of the servo motor 4 by changing the output voltage to achieve constant tension unwinding of the warp yarn.

[0017] Since the motor 4 and the controller 5 are installed in the electrical cavity 3, the motor 4 and the controller 5 can be prevented from being disturbed by external factors and affecting the control accuracy, such as dust entering the motor 4 or the controller 5. Due to the existence of the electrical cavity 3, an additional heat dissipation mechanism is required to assist the motor 4 in dissipating heat. Therefore, ventilation holes 6 and heat dissipation fans 7 are provided on the cavity wall of the electrical cavity 3. As shown in the attached figure, Figure 2 As shown in FIG, there is a motor array 8 in the electrical cavity 3, and the motor array 8 is composed of a plurality of motors 4. The ventilation holes 6 and the heat dissipation fan 7 are respectively located on both sides of the motor array 8 to generate a heat dissipation airflow in the gap of the motor array 8, thereby dissipating the heat of the motor 4 and preventing overheating in the electrical cavity 3.

[0018] As attached Figure 2 As shown in , the multiple motors 4 in the motor array 8 are arranged in rows and columns, and the arrangement direction of the motors 4 in the same column is the vertical direction. The arrangement direction of the motors 4 in the same row is inclined at a certain angle to the horizontal direction, and the inclination angles of the arrangement directions of the motors 4 in different rows are different. Correspondingly, the yarn reels 2 are also arranged in rows and columns, and the arrangement direction of the yarn reels 2 in the same row is also inclined at a certain angle to the horizontal direction, so that the warp yarns drawn from the yarn reel can be staggered with each other. Due to the arrangement of the motors 4, the opening direction of the ventilation holes 6 corresponds to the vertical direction to obtain a better heat dissipation effect. If the opening direction of the ventilation holes 6 is horizontal, the motors 4 arranged in a horizontal tilt will block the airflow and affect the heat dissipation effect.

[0019] In a specific application, not all motors 4 arranged in rows are arranged at an angle. When there are a large number of motors 4 in the electrical cavity 3, some of the motors 4 in rows may be arranged in a horizontal direction without being tilted, so that the space occupied by the motor array 8 is smaller and the electrical cavity 3 can accommodate more motors 4.

[0020] As attached Figure 1 As shown in , the controller 5 is installed at the bottom of the electrical cavity 3 so that the controller 5 can be installed and repaired, and the controller 5 and the motor array 8 are staggered to each other so that the motor 4 can be installed and repaired, which is convenient for operation. The ventilation hole 6 is opened at the top of the electrical cavity 3, and the opening range of the ventilation hole 6 covers the motor array 8. Since the opening of the ventilation hole 6 is oriented in the vertical direction, the ventilation hole 6 is either located at the bottom of the electrical cavity 3 or at the top of the electrical cavity 3, and the controller 5 is already installed at the bottom of the electrical cavity 3, so the ventilation hole 6 is more suitable to be opened at the top of the electrical cavity 3 so that the ventilation hole 6 can have a larger coverage. The top of the electrical cavity 3 can be only a single large-area ventilation hole 6, or it can be a plurality of small-area ventilation holes 6. Since the ventilation hole 6 is located at the top of the electrical cavity 3, the heat dissipation fan 7 is installed at the bottom of the electrical cavity 3 so that the ventilation hole 6 and the heat dissipation fan 7 are located on opposite sides of the motor array 8.

[0021] A filter is installed in the ventilation hole 6 to filter out dust and particles in the air.

[0022] The motors 4 in the bottom row are arranged obliquely, and the installation position of the controller 5 is close to the lower oblique end of the motors 4 in the bottom row; the installation position of the heat dissipation fan 7 is close to the upper oblique end of the motors 4 in the bottom row. On the side where the heat dissipation fan 7 is located, the distance between the motor 4 and the bottom of the electrical cavity 3 is larger, and the ventilation effect of the heat dissipation fan 7 will be better. In addition, as shown in the attached Figure 2 As shown in , the motor array 8 is arranged from sparse to dense along the horizontal direction, and the area where the motors 4 are densely packed is less likely to dissipate heat, while the cooling fan 7 is close to the side of the motor array 8 where the motors 4 are densely packed, thereby improving the heat dissipation effect on the area where the motors 4 are densely packed.

[0023] The unwinding frame 1 is provided with a frame 9 on the back, and a movable door plate 11 is installed on the frame opening of the frame 9. The unwinding frame 1, the frame 9 and the movable door plate 11 enclose the electrical cavity 3. When the movable door plate 11 is opened, the electrical cavity 3 is exposed. The ventilation holes 6 are correspondingly provided at the top of the frame 9, and the heat dissipation fan 7 is provided at the bottom of one side of the frame 9. Figure 1 In one embodiment shown in FIG. 1 , the movable door panel 11 can be opened and closed. When the movable door panel 11 is opened, the electrical cavity 3 is exposed, so that the motor 4 and the controller 5 can be easily installed or repaired.

[0024] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
