For ordinary technicians in this field, the specific meanings of the above terms in this embodiment can be understood according to specific circumstances.

[0029] In order to make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0030] The applicant found that the main reason for the excessively fast rotation speed of the wire-winding reel is that the wire-winding reel is a high-speed rotating component and rotates in the opposite direction to the needle roller. During the wire guiding process, the wire-winding reel and the needle roller need to interlace with each other. Since the speed of the wire-winding reel is too fast, the tobacco shreds will be subjected to greater force during the wire-winding process. At the same time, the wire-winding reel and the needle roller are driven by different motors, and the speed of the motor's drive shaft is usually very fast, which makes it difficult to control the speed of the wire-winding reel when it is directly driven by the motor.

[0031] Reference Figure 1 and Figure 2 The present invention provides a thread-elasticating device, comprising: a needle roller, a thread-elasticating reel and a motor 5, wherein a transmission assembly is arranged at the end of the needle roller, wherein the transmission assembly comprises a coaxial first gear 1 and a second gear 2, wherein the diameter of the first gear 1 is larger than the diameter of the second gear 2; the coaxial first gear 1 and the second gear 2, wherein the diameter of the first gear 1 is larger than the diameter of the second gear 2, wherein the first gear 1 is integrally formed with the second gear 2 and the needle roller, and the needle roller and the second gear 2 are driven to rotate by the rotation of the first gear 1; the thread-elasticating reel is arranged below the needle roller, wherein the thread-elasticating reel comprises a transmission shaft 47, wherein a third gear 4 is arranged at the end of the transmission shaft 47, and the third gear 4 is connected to the second gear 2 by a first synchronous belt 3; the first synchronous belt 3 is a toothed belt, and is meshed with the third gear 4 and the second gear 2, and the third gear 4 is driven to rotate by the second gear 2; the motor 5 is rotationally connected with the first gear 1, and is used to provide power to the first gear 1, and the first gear 1 drives the second gear 2 and the third gear 4 to rotate, so that the needle roller and the thread-elasticating reel rotate. By not directly driving the wire-springing reel to rotate with the motor 5, the rotation speed of the wire-springing reel can be slowed down through the transmission between gears, and the wire-springing reel and the needle roller are driven by the same motor 5. It is also possible to increase or decrease the speed of the needle roller and the wire-springing reel at the same time according to the speed of the equipment, thereby reducing the breakage of the tobacco and greatly improving the quality of the tobacco.

[0032] In an implementable embodiment, it further includes a tensioning seat 42 and two tensioning pulleys 41, the tensioning seat 42 is arranged on the elastic wire reel, the two tensioning pulleys 41 are respectively mounted on the tensioning seat 42 and symmetrically arranged on both sides of the third gear 4, and the two tensioning pulleys 41 are respectively rotatably connected with the first synchronous belt 3 for tensioning the first synchronous belt 3. The two tensioning pulleys 41 are respectively mounted on the tensioning seat 42 through the fixing pin 45, and a first bearing 44 is arranged between the tensioning pulley 41 and the fixing pin 45 so that the tensioning pulley 41 can rotate around the fixing pin 45.

[0033] In this embodiment, the tensioning pulley 41 is used to tension the first synchronous belt 3. Figure 2For example, the first synchronous belt 3 passes through the bottom of the left tension pulley 41, the top of the third gear 4 and the bottom of the right tension pulley 41 in sequence, and then meshes with the second gear 2. The two tension pulleys 41 tighten the first synchronous belt 3 to prevent the first synchronous belt 3 from loosening. The two tension pulleys 41 are assembled on the tensioning seat 42 through the fixing pin 45. In order to facilitate the rotation of the tension pulleys 41, an assembly hole is opened in the middle of each tension pulley 41, and a first bearing 44 is provided on the inner side wall of the assembly hole. The first bearing 44 is provided between the tension pulley 41 and the fixing pin 45, so that the tension pulley 41 can rotate around the fixing pin 45.

[0034] In an implementable embodiment, it further includes a bearing seat 43, which has a through hole. The bearing seat 43 is sleeved on the transmission shaft 47 through the through hole, and a second bearing 48 is provided on the inner side wall of the through hole so that the transmission shaft 47 can rotate in the through hole.

[0035] In this embodiment, the transmission shaft 47 rotates in the through hole through the second bearing 48. In the actual production process, due to production specification restrictions, two second bearings 48 are usually provided, and a spacer sleeve is provided between two adjacent second bearings 48 to prevent the second bearings 48 from being displaced during use, and to limit the positions of the two second bearings 48 to extend their service life.

[0036] In an operative embodiment, the transmission assembly further comprises: a first driving shaft, one end of which is connected to the first gear 1, and the other end of which is provided with a first driven wheel; a second driving shaft, two ends of which are provided with a second driven wheel and a third driven wheel, respectively, the second driven wheel is meshed and connected with the first driven gear; a third driving shaft, one end of which is provided with a fourth driven wheel, the third driven wheel is meshed and connected with the fourth driven wheel, and the other end of the third driving shaft is connected with the needle roller. It also comprises a reduction wheel 6, which is arranged between the motor 5 and the needle roller, and the reduction wheel 6 is provided with a reduction gear coaxial with the reduction wheel 6, the motor 5 is connected to the reduction wheel 6 through the second synchronous belt 7, and the reduction gear is connected to the first gear 1 through the third synchronous belt 8. It also comprises a tensioning wheel 9, which is arranged between the reduction wheel 6 and the first gear 1, and is used to tension the third synchronous belt 8. The speed ratio of the elastic reel to the needle roller is 10:1.

[0037] In this embodiment, the reduction wheel 6 is used to control the rotation speed of the spring wire reel and the needle roller to prevent the needle roller and the spring wire reel from rotating too fast and affecting the use. The tensioning wheel 9 is used to tension the third synchronous belt 8 to prevent the third synchronous belt 8 from loosening. According to the applicant's test, when the speed ratio of the spring wire reel to the needle roller is 10:1, the degree of tobacco shreds can be reduced to the greatest extent without affecting the efficiency of wire feeding. In this application, the first synchronous belt 3, the second synchronous belt 7 and the third synchronous belt 8 are all toothed synchronous belts;

[0038] The following example takes the first gear 1 having 52 teeth, the second gear 2 having 30 teeth, the third gear 4 having 30 teeth, the reduction wheel 6 having 43 teeth, the reduction gear having 13 teeth, the motor 5 having 12 teeth, the first driven wheel having 25 teeth, the second driven wheel having 93 teeth, the third driven wheel having 24 teeth, and the fourth driven wheel having 60 teeth as an example;

[0039] The rotation process of the needle roller is as follows: the motor 5 drives the reduction wheel 6 to rotate through the second synchronous belt 7, and then drives the reduction gear coaxial with the reduction wheel 6 to rotate through the third synchronous belt 8, and the first gear 1 drives the first drive shaft to rotate, and then drives the first driven wheel, the second driven wheel, the third driven wheel and the fourth driven wheel in turn, and finally the needle roller is driven by the third drive shaft to rotate.

[0040] Therefore, the gear ratio between the motor and the reduction wheel is:

[0041] The gear ratio between the reduction gear and the first gear is:

[0042] The gear ratio between the first driven wheel and the second driven wheel is:

[0043] The gear ratio between the third driven wheel and the fourth driven wheel is:

[0044] According to the transmission balance equation:

[0045]

[0046] That is, the rotation speed of the motor 5 is related to the rotation speed of the needle roller. For example, when the maximum rotation speed of the motor 5 is 3000 r / min, the maximum rotation speed of the needle roller is about 22.5 r / min.

[0047] The rotation process of the elastic reel is as follows: the motor 5 drives the reduction wheel 6 to rotate through the second synchronous belt 7, and then drives the reduction gear coaxial with the reduction wheel 6 to rotate through the third synchronous belt 8, and the first gear 1 drives the first driving shaft to rotate, and then drives the first driven wheel, the second driven wheel, the third driven wheel and the fourth driven wheel in turn, and finally the needle roller is driven to rotate by the third driving shaft.

[0048] Therefore, the transmission relationship of the needle roller is: the motor 5 drives the reduction wheel 6 to rotate through the second synchronous belt 7, and then drives the reduction gear coaxial with the reduction wheel 6 to rotate through the third synchronous belt 8, and the second gear 2 drives the third gear 4 to rotate through the first synchronous belt 3, thereby driving the elastic reel.

[0049] Therefore, the transmission relationship of the silk reel is:

[0050] Therefore, the gear ratio between the motor and the reduction wheel is:

[0051] The gear ratio between the reduction gear and the first gear is:

[0052] According to the transmission balance equation:

[0053]

[0054] Taking the maximum speed of motor 5 as 3000r / min as an example, the maximum speed of the springing reel is about 209.3r / min. That is, the speed ratio of the springing reel to the needle roller is close to 10:1, and the springing reel is still much faster than the needle roller, which does not affect the transportation of tobacco and can also minimize the degree of tobacco crushing.

[0055] In an practicable embodiment, it further includes a conveyor belt and a thread throwing roller. The conveyor belt is arranged below the thread-springing reel and is used to receive the tobacco from the thread-springing reel and convey the tobacco to the thread throwing roller.

[0056] In this embodiment, a uniform wire plate is also included, which makes the tobacco shreds evenly distributed on the needle roller. The needle roller is mainly composed of a rotating roller and a needle plate. 36 needle plates are installed on the rotating roller, and their function is to take out tobacco shreds from the metering trough. The net reel is a rotating roller with 596 spring pins installed on an axis. When rotating, the spring pins pass through the gap between the steel needles of the needle roller, thereby bouncing the tobacco shreds off the needle roller and falling onto the tobacco conveyor belt. The conveyor belt will transport it to the net roller, and the net roller will throw the tobacco shreds.

[0057] In an implementable embodiment, a transition pulley 46 is further included, with a mounting hole, the transition pulley 46 is sleeved on the bearing seat 43 through the mounting hole, and a third bearing 49 is provided on the inner side wall of the mounting hole, so that the transition pulley 46 can rotate around the bearing seat 43, and the wire throwing roller is rotatably connected to the transition pulley 46. Two third bearings 49 are provided, which are spaced apart in the mounting hole, and a spacer is provided at the interval between the two third bearings 49.

[0058] In this embodiment, the transition pulley 46 is used to connect with the motor 5 before the spring reel to play a transition role.

[0059] Although the present invention has been illustrated and described with reference to certain preferred embodiments of the present invention, it should be understood by those skilled in the art that the above is a further detailed description of the present invention in conjunction with specific embodiments, and it cannot be determined that the specific implementation of the present invention is limited to these descriptions. Those skilled in the art may make various changes in form and details, including making several simple deductions or substitutions, without departing from the spirit and scope of the present invention.
