[0001] This utility model relates to the field of fabric production technology, specifically to a negative ion powder addition device for spunlace nonwoven fabric. Background Technology

[0002] In the fiber preparation stage of spunlace nonwoven fabric production, negative ion powder needs to be dried and added to the molten polymer at a certain mass ratio for uniform dispersion. After cooling and solidification, it is then pulverized and ball-milled to obtain particles containing negative ion powder. These particles are then melt-blended with other materials such as polyester using a twin-screw extruder, extruded and granulated, and dried to obtain chips suitable for spinning.

[0003] When adding negative ion powder, it needs to be added in a certain ratio to the polymer. Therefore, workers need to weigh the added negative ion powder or place it in a graduated container and measure its volume. Both methods are inefficient. To address this, a negative ion powder adding device using spunlace nonwoven fabric is proposed. Utility Model Content

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] This utility model provides a technical solution: such as Figures 1 to 4 As shown in this embodiment, a negative ion powder adding device for spunlace nonwoven fabric includes a fixed base 1, a material box 2 is arranged above the fixed base 1, the bottom of the material box 2 is fixedly connected to the fixed base 1 through a connecting frame 15, a conveying pipe 3 is fixedly connected to the bottom of the material box 2, both ends of the conveying pipe 3 are in a closed state, the upper end of the conveying pipe 3 is in a communication state with the bottom of the material box 2, a discharge port 11 is opened at the bottom of the end of the conveying pipe 3 away from the material box 2, a rotating shaft 9 is arranged inside the conveying pipe 3, the two ends of the rotating shaft 9 are respectively rotatably connected to the inner walls of the two ends of the conveying pipe 3, a spiral blade 10 is sleeved on the outer wall of the rotating shaft 9, the spiral blade 10 is fixedly connected to the rotating shaft 9, and a driving mechanism acting on the rotating shaft 9 is arranged outside the conveying pipe 3.

[0021] The drive mechanism consists of a first motor 4, a mounting plate 5, a first synchronous pulley 6, a second synchronous pulley 7, and a synchronous belt 8. The mounting plate 5 is fixedly mounted on the side wall of the fixed base 1. The first motor 4 is fixedly mounted on the upper end of the mounting plate 5. The output shaft of the first motor 4 is fixedly connected to the first synchronous pulley 6. One end of the rotating shaft 9 passes through the end of the conveying pipe 3 and extends to the outside of the conveying pipe 3. The extended end of the rotating shaft 9 is fixedly connected to the second synchronous pulley 7. The outer surfaces of the first synchronous pulley 6 and the second synchronous pulley 7 are fitted with a synchronous belt 8, which is adapted to the first synchronous pulley 6 and the second synchronous pulley 7 respectively.

[0022] In use, starting motor 4 drives synchronous pulley 6 to rotate. Under the action of synchronous belt 8, synchronous pulley 7 will rotate accordingly, thereby driving rotating shaft 9 to rotate. Rotating shaft 9 will drive spiral blade 10 to rotate. Spiral blade 10 can transport negative ion powder in conveying pipe 3 to discharge port 11 of conveying pipe 3. The amount of negative ion powder transported by spiral blade 10 for each fixed rotation angle is fixed. This amount depends on the pitch of spiral blade 10 and the inner diameter of conveying pipe 3 and can be manually controlled. Assuming that the amount of negative ion powder transported by spiral blade 10 for one rotation is n and the amount of negative ion powder to be added is m, then by controlling spiral blade 10 to rotate m / n times, the quantitative addition of negative ion powder can be quickly achieved.

[0023] It is important to note that motor 4 is a stepper motor, and its rotation number and angle can be controlled by the number of input pulses to ensure that the rotation number of the helical blade 10 can be manually controlled. It is also important to note that the diameters of synchronous pulley 6 and synchronous pulley 7 are different. To make the helical blade 10 (i.e., the rotating shaft 9) rotate m / n times, the output shaft of motor 4 needs to be controlled according to the diameter ratio of synchronous pulley 6 and synchronous pulley 7. For example, assuming the diameter ratio of synchronous pulley 6 and synchronous pulley 7 is a / b, then to make the helical blade 10 (i.e., the rotating shaft 9) rotate m / n times, the output shaft of motor 4 needs to rotate mb / na times.

[0024] The diameter of the first synchronous pulley 6 is smaller than the diameter of the second synchronous pulley 7.

[0025] With this configuration, a force-saving structure can be formed between the first synchronous pulley 6 and the second synchronous pulley 7, thereby reducing the stress on the output shaft of the first motor 4 and thus improving the service life of the first motor 4.

[0026] The material box 2 is equipped with a rotating rod 13 inside. The two ends of the rotating rod 13 are rotatably connected to the two inner walls of the material box 2. A second motor 12 is fixedly installed on the outer wall of the material box 2. The output shaft of the second motor 12 is fixedly connected to the rotating rod 13. A toggle plate 14 is fixedly connected to the outer wall of the rotating rod 13.

[0027] The rotating rod 13 is driven by the second motor 12 to rotate. The rotating rod 13 can move the negative ion powder in the material box 2 to ensure that it can smoothly enter the conveying pipe 3. The second motor 12 can be a servo motor, which can set the speed by inputting a 0-10V voltage or a 4-20mA current signal (such as PLC output analog command). The output shaft of the second motor 12 needs to rotate slowly to avoid splashing the negative ion powder out of the material box 2.

[0028] This utility model provides a negative ion powder adding device for spunlace nonwoven fabric, the specific working principle of which is as follows:

[0029] The first motor 4 is started, which drives the first synchronous pulley 6 to rotate. Under the action of the synchronous belt 8, the second synchronous pulley 7 will rotate accordingly, thereby driving the rotating shaft 9 to rotate. The rotation of the rotating shaft 9 will drive the spiral blade 10 to rotate. The spiral blade 10 can transport the negative ion powder in the conveying pipe 3 to the discharge port 11 of the conveying pipe 3. The amount of negative ion powder transported by the spiral blade 10 for each fixed rotation angle is fixed. This amount depends on the pitch of the spiral blade 10 and the inner diameter of the conveying pipe 3, and can be manually controlled. Assuming that the amount of negative ion powder transported by the spiral blade 10 for one rotation is n, and the amount of negative ion powder to be added is m, then it is only necessary to control the spiral blade 10 to rotate m / n times to quickly realize the quantitative addition of negative ion powder.

[0030] It is important to note that motor 4 is a stepper motor, and its rotation number and angle can be controlled by the number of input pulses to ensure that the rotation number of the helical blade 10 can be manually controlled. It is also important to note that the diameters of the first synchronous pulley 6 and the second synchronous pulley 7 are different. In order for the helical blade 10 (i.e., the rotating shaft 9) to rotate m / n times, the output shaft of motor 4 needs to be controlled to be converted according to the diameter ratio of the first synchronous pulley 6 and the second synchronous pulley 7. Assuming that the diameter ratio of the first synchronous pulley 6 and the second synchronous pulley 7 is a / b, then in order for the helical blade 10 (i.e., the rotating shaft 9) to rotate m / n times, the output shaft of motor 4 needs to rotate mb / na times.

[0031] The rotating rod 13 is driven by the second motor 12 to rotate. The rotating rod 13 can move the negative ion powder in the material box 2 to ensure that it can smoothly enter the conveying pipe 3. The second motor 12 can be a servo motor, which can set the speed by inputting a 0-10V voltage or a 4-20mA current signal (such as PLC output analog command). The output shaft of the second motor 12 needs to rotate slowly to avoid splashing the negative ion powder out of the material box 2.

[0032] Among them, motor 4 can be a stepper motor of model 57HS04, and motor 12 can be a servo motor of the IS620P series.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
