[0029] The existing specific implementation of the tobacco filter rod tow opening includes: tow extraction, tow opening, tow conveying, plasticizer application, and output forming. The working principle is as follows: after the tow is extracted, it is directly conveyed to the plasticizer application part through each pair of opening rollers and conveying rollers for plasticizer application, and then output to the filter rod forming area. The following problems exist in the prior art: 1. Due to the unstable pressure of the pair of opening rollers, the width of the tow output after opening fluctuates, indirectly affecting the plasticizer application effect; 2. The tow width is unstable and is adjusted by manual observation, and there are occasional situations beyond the process range, resulting in certain quality risks.
[0030] To solve the above problems, this embodiment provides a tow processing device. Refer to Figure 1, including a conveyor belt 1, a loosening assembly 2 and a detecting member 3. The conveyor belt 1 is used for conveying a tow 100; the loosening assembly 2 includes a first pair of loosening rollers 21 and a second pair of loosening rollers 22. The first pair of loosening rollers 21 and the second pair of loosening rollers 22 are both arranged on the upper and lower sides of the conveyor belt 1. The rolling speed of the first pair of loosening rollers 21 is less than that of the second pair of loosening rollers 22. The tow 100 can pass through the first pair of loosening rollers 21 and the second pair of loosening rollers 22 along with the conveyor belt 1; the detecting member 3 is arranged on the front side of the second pair of loosening rollers 22 along the conveying direction, and is used for detecting the width of the loosened tow 100 and the width of the conveyor belt 1. Through the speed difference between the first pair of loosening rollers 21 and the second pair of loosening rollers 22, not only can the tow 100 be loosened by pressure, but also the tow 100 can be longitudinally loosened, increasing the loosening stability of the tow 100; by detecting the width of the loosened tow 100 with the detecting member 3, the width of the conveyor belt 1 at this part can be detected at the same time. When the conveyor belt 1 has an accidental turnover, a signal is sent out, improving the accuracy of the width of the tow after loosening, reducing the quality risk, and ensuring the normal operation of the equipment.
[0031] Specifically, the detecting member 3 is set as a matrix optical fiber sensor. In other embodiments, the detecting member 3 can also be set as a proximity sensor or a distance sensor; the detection frequency of the detecting member 3 is 1 time / s. Through high-frequency detection, the width data of the tow 100 can be mastered in real time, improving the accuracy of measuring the width of the tow 100.
[0032] Further, referring to Figure 2 , the tow processing equipment further includes a support member 5. The support member 5 is used for fixing the detecting member 3 above the conveyor belt 1. In this embodiment, the support member 5 is set as a box body with an opening on one side, and the opening faces the conveyor belt 1. The detecting member 3 is arranged in the box body. One end of the box body is provided with a threaded hole, and the box body can be fixed to the outside by screws. In other embodiments, the support member 5 can also be set as a support rod, etc.
[0033] Further, the loosening assembly 2 further includes an air loosener 23. There are at least two air looseners 23. The two air looseners 23 are respectively arranged on the rear side of the first pair of loosening rollers 21 along the conveying direction and on the front side of the detecting member 3 along the conveying direction. In this embodiment, there are three air looseners 23. Two are arranged on the rear side of the first pair of loosening rollers 21 along the conveying direction, and one is arranged on the front side of the detecting member 3 along the conveying direction to increase the loosening width of the tow 100. Since the air loosener 23 is a very mature technology in the art, the specific structure and working principle of the air loosener 23 will not be specifically described here.
[0034] Further, the tow processing device further includes a central control component, which is communicatively connected to the first opening roller pair 21, the second opening roller pair 22, the air opener 23, and the detection component 3. The detection component 3 detects the width of the tow 100 and sends a signal to the central control component. The central control component can control the rolling speeds of the first opening roller pair 21 and the second opening roller pair 22, as well as the air pressure and blowing frequency of the air opener 23 according to the feedback signal of the detection component 3, so as to precisely control the width of the tow 100.
[0035] Further, the tow processing device further includes a pre-tensioning roller pair 4, which is arranged at the rear side of the first opening roller pair 21 along the conveying direction. The pre-tensioning roller pair 4 can roll as the conveyor belt 1 moves. The pre-tensioning roller pair 4 can perform pressure pre-tensioning on the tow 100 through the pressure between the two rollers, and the pre-tensioning roller pair 4 is set as a driven roller, which can support the conveyor belt 1 and increase the stability of the conveyor belt 1. Further, multiple pre-tensioning roller pairs 4 can be arranged at intervals on the conveyor belt 1.
[0036] Further, the tow processing device further includes a plasticizing component 6, which is arranged at the front side of the detection component 3 along the conveying direction and is used to apply a plasticizer to the tow 100. Specifically, the plasticizer includes triacetin, triethyl citrate, polyols, fats, etc., which will not be elaborated here.
[0037] Further, the tow processing device further includes an output roller 7, which is arranged at the front side of the plasticizing component 6 along the conveying direction. The output roller 7 is used to transport the tow 100 after the plasticizer is applied to the next processing process. In this embodiment, two output rollers 7 are provided, including a driving roller and a driven roller, both of which are arranged below the conveyor belt 1.
[0038] Further, the tow processing device further includes a filter rod forming component, which is arranged at the front side of the plasticizing component 6 along the conveying direction and is used to form the tow 100 into a rod body. The tow 100 is transported to the filter rod forming component through the output roller 7 to form a filter tip. Since the filter rod forming component is a very mature technology in the art, its specific structure and processing process will not be specifically described here.
[0039] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments, and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
