[0034] Among them, reference Figures 1 to 4As shown, the filament belt conveying device 10 provided in the embodiment of the present invention includes a filament belt package 300. The filament belt 301 extracted from the filament belt package 300 can be used for making filter rods in the tobacco industry. As the filament belt 301 is continuously extracted from the filament belt package 300, the overall height of the filament belt package 300 will be adjusted accordingly. The filament belt conveying device 10 provided in the embodiment of the present invention can ensure that the filament belt 301 is relatively stable during transportation, thereby improving the yield rate of the filter rods.

[0035] Specifically, refer to Figures 1 to 4 As shown, the yarn band conveying device 10 includes a positioning module 100 and a guiding module 200, wherein the guiding module 200 includes a fixing unit 210 and a guiding unit 220, wherein the guiding unit 220 can adjust the angle of the transmitted yarn band 301; wherein the fixing unit 210 is connected to the positioning module 100, and the height of the fixing unit 210 can be adjusted through the positioning module 100, thereby realizing the adjustment of the height of the transportation process of the yarn band 301; the combination of the positioning module 100 and the guiding module 200 can provide a clamping force for the yarn band 301, thereby ensuring that the yarn band 301 is pulled out of the yarn package 300, thereby realizing the transportation of the yarn band 301.

The arc space surrounded by the middle portion 101b is used to achieve contact with the lifting arm. Optionally, the lifting arm can be understood as a mechanical arm for producing components corresponding to the filter rod. The mechanical arm can adjust the height and position, and then the positioning module 100 follows the movement of the mechanical arm to adjust the guide module 200 and the filament belt 301. The specific lifting arm is not shown in the figure. Furthermore, the vertical plate 103 is mechanically connected to the arm plate 102. There are various ways to connect the vertical plate 103 and the arm plate 102. It can be a threaded connection, a mortise and tenon connection, or bonding with a colloid, etc. The embodiment of the present invention does not specifically limit this.

[0037] Further, the fixing unit 210 in the guide module 200 includes a corner bracket 211, a bracket 212 and a fixing plate 213, referring to Figure 1 , Figure 3 and Figure 4As shown, the angle bracket 211 includes a first section 211a and a second section 211b, and the plane where the first section 211a is located intersects with the plane where the second section 211b is located. The first section 211a and the second section 211b can be understood as the bending sections of the angle bracket 211 in two different directions. Furthermore, the vertical plate 103 is threadedly connected to the first section 211a, thereby realizing the connection relationship between the guide module 200 and the positioning module 100. The second section 211b of the vertical plate 103 is threadedly connected to the bracket 212 and the fixing plate 213, thereby realizing the connection relationship between the fixing unit 210 and the guide unit 220 in the guide module 200. Figure 1 , Figure 3 and Figure 4 As shown, the first surface and the second surface of the second section 211b can be understood as the top and bottom sides, wherein the bracket 212 is threadedly connected to one side, and the fixing plate 213 is threadedly connected to the other side.

[0038] For further reference, Figure 1 , Figure 3 and Figure 4 As shown, the guide unit 220 includes a guide ring 221, a connecting sleeve 222, an intermediate connecting portion 223 and an air pipe 224, wherein the guide ring 221 includes a ring body portion 221a and a support rod portion 221b which are connected to each other, the support rod portion 221b is threadedly connected to the bracket 212, the guide ring 221 is structurally fixed by the support rod portion 221b, and the transmission of the filament belt 301 can be ensured to be located at the center of the ring body portion 221a through adjustment of the threaded connection. Furthermore, the connecting sleeve 222 is threadedly connected to the fixed plate 213, and the intermediate connecting portion 223 is fixedly connected to the connecting sleeve 222, wherein the center of the ring body portion 221a, the center of the connecting sleeve 222 and the center of the intermediate connecting portion 223 are in the same straight line (so that the axis of the channel of the guide unit 220 and the central position of the conveying of the tow belt 301 are in the same plane, and the installation and positioning are more accurate), which can ensure that the tow belt 301 provided by the tow package 300 is conveyed through the ring body portion 221a, the intermediate connecting portion 223 and the connecting sleeve 222 in sequence. The connecting sleeve 222 can ensure the connection relationship with the fixed unit 210. Combined with the specific structure of the guide unit 220 provided in the embodiment of the present invention, it can be understood that it is composed of a set of channel-like combinations, and this type of structure helps to improve the conveying effect of the tow belt 301. Furthermore, the middle connection portion 223 also includes a gas input port, and the air pipe 224 is connected to the gas input port. The gas injected through the air pipe 224 can adjust the angle force and the air supply force, thereby ensuring that the transmission of the filament belt 301 is more stable.

[0039] Specifically, refer to Figure 1As shown, the fiber bundle conveying device 10 also includes a bundle height detection module 400, which is located on the side of the bundle 300, and the height value of the bundle 300 can be detected by the bundle height detection module 400. It can be understood that the height of the bundle 300 will change with the continuous transmission of the bundle 301, and for the height change of the bundle 300, the clamping force provided by the current position of the positioning module 100 and the guide module 200 that adjust the position in advance to meet the appropriate clamping force may not ensure that the bundle 301 continues to be smoothly transmitted. Therefore, the bundle conveying device 10 can ensure the balance of the clamping force and the air supply force by adjusting the gas flow rate or flow rate in the air pipe 224, thereby ensuring the smooth transmission of the bundle 301.

[0040] Specifically, refer to Figure 1 As shown, the fiber belt conveying device 10 also includes an air delivery control module 500, which includes a control unit 510 and a proportional control valve 520, and the control unit 510 is connected to the fiber bundle height detection module 400 and the proportional control valve 520 respectively. The control module 510 can adjust the opening of the proportional control valve 520 in accordance with the acquired height value and the preset corresponding gas flow rate and flow rate, so as to ensure the balance of the clamping force and the air delivery force currently provided by the guide module 200 and the positioning module 100 in the fiber belt conveying device 10, and ensure the smooth transmission of the fiber belt 301. It can be understood that by adding the positioning module 100 and the guide module 200 to the lifting arm, and adding the fiber bundle height detection module 400 and the air delivery control module 500 to the fiber bundle 301 conveying process, the influence of the height change of the fiber bundle 300 on the conveying stability of the fiber bundle 301 is fundamentally eliminated, and the conveying stability of the fiber bundle 301 is improved.

[0041] Optionally, the air delivery control module 500 may also include a human-machine interaction interface and an indicator light, etc. The air delivery control module 500 may provide functions such as real-time display and real-time automatic adjustment of air delivery pressure through the human-machine interaction interface, and improve the intelligence and visibility of the air delivery control system, thereby improving the stability of the conveying of the filament belt 301. Furthermore, when the height value of the filament bundle 300 is zero, the indicator light may be controlled to light up red, thereby prompting the operator to prepare to replace the filament bundle 300, thereby preventing equipment shutdown caused by the exhaustion of the filament bundle 300 and improving equipment efficiency.

[0042] In summary, an embodiment of the present invention provides a yarn belt conveying device, which includes a yarn bundle height detection module and an air delivery control module. The control module in the air delivery control module adjusts the opening of the proportional control valve according to the acquired height value. The yarn belt conveying device achieves a balance between the clamping force and the wind force by adjusting the wind force transmitted by the air pipe according to the change in the yarn bundle height, thereby ensuring that the transportation of the yarn belt is more stable.

[0043] Continue to refer Figure 1 As shown, the air delivery control module 500 also includes a switch solenoid valve 530, and the control unit 510 is connected to the switch solenoid valve 530; the control module 510 adjusts the on or off state of the switch solenoid valve 530 according to the acquired height value.

[0044] For further reference, Figure 1 As shown, the air delivery control module 500 also includes a switch solenoid valve 530 connected to the control unit 510. The on and off of the switch solenoid valve 530 is used to adjust whether there is gas entering the air pipe 224. The switch solenoid valve 530 can be understood as an adjustment unit with or without gas input. The opening size of the proportional control valve 520 is used to adjust the gas flow and flow rate in the air pipe 224. The proportional control valve 520 can be understood as an adjustment unit with the size of the gas input.

[0045] Continue to refer Figure 1 , Figure 3 and Figure 4 As shown, the intermediate connection part 223 includes an intermediate relay 223a and an outlet guide 223b which are connected to each other. The intermediate relay 223a is located on a side of the outlet guide 223b close to the connection sleeve 222, and the air pipe 224 is connected to the intermediate relay 223a.

[0046] Among them, the intermediate connection part 223 includes an intermediate relay 223a and an outlet guide 223b, wherein the air pipe 224 is connected to the intermediate relay 223a. By setting the intermediate relay 223a, further control of the gas inflow in the air pipe 224 can be achieved, that is, when the intermediate relay 223a is turned on, the gas in the air pipe 224 can be input to achieve the adjustment of the air supply force; if the intermediate relay 223a is turned off, the gas in the air pipe 224 will not be input. Therefore, the setting of the intermediate relay 223a is equivalent to adding a safety device for adjusting the wind force. The setting of the outlet guide 223b can be understood as an adjustment of a transmission direction of the wind force transmitted to the intermediate connection part 223, ensuring that the gas transmitted to the intermediate connection part 223 can be transmitted to the transportation area of ​​the filament belt 301.

[0047] Optional, reference Figure 1 , Figure 3 and Figure 4 As shown, the outlet guide 223b includes a bell-mouth guide, and the center of the bell-mouth guide, the center of the ring body portion 221a and the center of the connecting sleeve 222 are on the same straight line.

[0048] Specifically, refer to Figure 1 , Figure 3 and Figure 4As shown, the shape setting of the outlet guide 223b is diverse, and can be a bell-mouth guide. Furthermore, by setting the intermediate connecting portion 223, the filament belt 301 is constrained and guided layer by layer, so that the conveying process of the filament belt 301 can achieve better positioning and gathering effects. The intermediate relay 223a can be connected to the high-pressure jet through the air pipe 224, providing an upward airflow in the guide channel, forming an auxiliary conveying force, slowing down the conveying force of the filament belt 301, and at the same time eliminating the gravity of the filament belt 301, reducing the interference factors caused by the height of the filament package 300 and the swing of the filament belt 301, and improving the transmission stability of the filament belt 301.

[0049] Continue to refer Figure 1 , Figure 2 and Figure 4 As shown, the clamp 101 includes a first clamp 1011 and a second clamp 1012 which are arranged opposite to each other, the end 101a of the first clamp 1011 and the end 101a of the second clamp 1012 are threadedly connected, the middle portion 101b of the first clamp 1011 and the middle portion 101b of the second clamp 1012 are arranged opposite to each other, and the middle portion 101b of the first clamp 1011 and the middle portion 101b of the second clamp 1012 surround the lifting arm; the inner diameter of the middle portion 101b of the first clamp 1011 is less than or equal to the outer diameter of the lifting arm, and the inner diameter of the middle portion 101b of the second clamp 1012 is less than or equal to the outer diameter of the lifting arm.

[0050] For further reference, Figure 2 and Figure 4 As shown, the clamping plate 101 includes a first clamping plate 1011 and a second clamping plate 1012, and the first clamping plate 1011 and the second clamping plate 1012 surround the two sides of the lifting arm to achieve position fixation with the lifting arm. Specifically, the end 101a of the first clamping plate 1011 and the end 101a of the second clamping plate 1012 are threadedly connected, the middle part 101b of the first clamping plate 1011 and the middle part 101b of the second clamping plate 1012 are arranged relatively, and the middle part 101b of the first clamping plate 1011 and the middle part 101b of the second clamping plate 1012 surround the lifting arm. The first clamping plate 1011 and the second clamping plate 1012 can be understood as two semicircular structures, which are connected to the lifting arm by surrounding the lifting arm to ensure the connection state of the positioning module 100 and the lifting arm.

[0051] Among them, the inner diameter of the middle part 101b of the first clamping plate 1011 is less than or equal to the outer diameter of the lifting arm, and the inner diameter of the middle part 101b of the second clamping plate 1012 is less than or equal to the outer diameter of the lifting arm. In this way, the positioning module 100 can be fixed at any position on the lifting arm of the forming machine by locking the fixing screws on the first clamping plate 1011 and the second clamping plate 1012, thereby improving the flexibility of the yarn belt conveying device 10 during installation.

The tow package 300 will block the transmission path of part of the photoelectric rays, and the light blocked by the tow package 300 will not be transmitted to the reflection plate 421, while the light not blocked by the tow package 300 can be transmitted to the reflection plate 421. With the continuous transmission of the tow belt 301 in the tow package 300, the height of the tow package 300 will decrease, and then the light transmitted to the reflection plate 421 will gradually increase. The control module 510 can be connected to the reflection unit 420, and the reflection plate 421 transmits the detected light value to the control module 510, and the control module 510 can realize the judgment of the height of the tow package 300.
