[0023] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments, and the preferred embodiments of the present invention are shown in the accompanying drawings. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0024] See also Figure 1As shown, the cigarette filter rod spiral propulsion device includes a lifting component 1 and a spiral propeller component 2. The spiral propeller component 2 is assembled and installed on the lifting component 1. The spiral propeller component 2 is used to drive the filter rods to be transported to the downstream forming equipment in an orderly manner through the rotation effect. The lifting component 1 is used to adjust the position of the spiral propeller component 2 in the horizontal and vertical directions.

[0025] See also Figure 2 As shown, the lifting assembly 1 includes a mounting base 111, a sliding base 112, a lifting cylinder assembly 113, an upper connecting plate 117 and a connecting piece 119; two sets of transverse guide rails 120 are arranged in parallel on the mounting base 111, a transverse slider 121 is arranged at the bottom of the sliding base 112 corresponding to the position of the transverse guide rail 120, and the sliding base 112 is slidably connected to the transverse guide rail 120 through the transverse slider 121; a lifting cylinder assembly 113 and two sets of vertical guide rails 114 are fixedly arranged on the sliding base 112, and the two sets of vertical guide rails 114 are symmetrically arranged on the The two sides of the lifting cylinder assembly 113; the lower part of the upper connecting plate 117 is connected with an adjustment pad 118, the adjustment pad 118 contacts the output end of the lifting cylinder assembly 113, the two sides of the upper connecting plate 117 are symmetrically connected with two groups of side connecting plates 116, the outer ends of the two groups of side connecting plates 116 are respectively connected with the connecting piece 119, and the connecting piece 119 is fixedly connected with the screw propeller assembly 2; the inner side of the side connecting plate 116 is provided with a vertical slider 115 corresponding to the position of the vertical guide rail 114, and the vertical slider 115 is slidably connected to the vertical guide rail 114. The output power of the lifting cylinder assembly 113 drives the screw propeller assembly 2 to rise and fall along the direction of the vertical guide rail by lifting the adjustment pad 118; by adjusting the position of the sliding base 112 on the transverse guide rail 120 (manually or with external power machinery), the position of the screw propeller assembly 2 in the horizontal direction is adjusted accordingly.

[0026] In an embodiment of the present invention, the upper connecting plate 117 and the adjusting pad 118 are screwed together by an adjusting bolt 123, and a locking nut 124 is provided on the screw connection. By adjusting the position of the adjusting bolt 123, the distance between the upper connecting plate 117 and the adjusting pad 118 is adjusted, thereby achieving fine adjustment of the height of the screw propeller assembly 2 in the vertical direction, and coarse adjustment of the height of the lifting cylinder assembly 113 in the vertical direction, thereby achieving precise adjustment of the height of the screw propeller assembly 2.

[0027] Limiting seats 125 are respectively provided on the mounting base plate 111 at both ends corresponding to the extension direction of the transverse guide rail 120, and limiting bolts 126 are screwed on the limiting seats 125. The limiting seats 125 cooperate with the limiting bolts 126 to limit the movement range of the sliding base 112 on the transverse guide rail 120, thereby preventing the sliding base 112 from separating from the transverse guide rail 120; according to the actual application scenario, the distance of the limiting bolts 126 on the limiting seats 125 can also be adjusted accordingly, thereby adjusting the movement range of the sliding base 112 on the transverse guide rail 120, that is, the movement range is increased or decreased according to the protruding length of the limiting bolts 126 on the limiting seats 125.

[0028] A support base 122 is fixedly disposed at the bottom of the installation base plate 111 , and the support base 122 is used to be fixedly connected to an external mechanism, thereby providing physical support for the installation base plate 111 and various components thereon.

[0029] See also Figure 3-5 As shown, the screw propeller assembly 2 includes a screw propulsion mechanism 20, an upper connecting frame 21, a drive motor assembly 27 and a protective cover.

The upper connecting frame 21 is assembled with a protective cover, which is arranged on the outside of the drive motor assembly 27 and the screw propulsion mechanism 20. The drive motor assembly 27 drives the screw propulsion mechanism 20 to rotate, cooperates with the protective cover, and drives the filter rods to be transported to the downstream molding equipment in an orderly manner.

[0030] In the embodiment of the present invention, the spiral propulsion mechanism 20 and the drive motor assembly 27 are detachably connected. By replacing the spiral propulsion mechanism 20 with different specifications and different thread sizes, it can be correspondingly applied to the sorting work of filter rods of different specifications.

[0031] The protective cover includes a bracket connecting plate 22, a rear bracket 23, a front bracket 24, a visible shield 25, a rear shield 26 and a side shield 28. The bracket connecting plate 22 is fixedly connected to the upper connecting frame 21. The front and rear ends of the bracket connecting plate 22 are respectively fixedly connected with the front bracket 24 and the rear bracket 23. The sides of the front bracket 24 and the rear bracket 23 are respectively combined and installed with a visible shield 25 and a side shield 28. The rear bracket 23 is covered with a rear shield 26 facing the direction of the spiral propulsion mechanism 20. The visible shield 25, the rear shield 26 and the side shield 28 cooperate to semi-enclose the spiral propulsion mechanism 20, so as to limit the filter rods arranged therein when the spiral propulsion mechanism 20 rotates.

[0032] The visual shield 25 is made of acrylic material, which is convenient for real-time observation of the working status of the spiral propulsion mechanism 20 and corresponding adjustment or maintenance, thereby improving the stability of the filter rod sorting work.

[0033] The cigarette filter rod spiral propulsion device described in the embodiment of the present invention utilizes a driving motor assembly 27 to drive the spiral propulsion mechanism 20 to rotate, thereby driving the filter rods to be transported downward in an orderly manner. The spiral propulsion mechanism 20 can be replaced with spiral propulsion mechanisms 20 of different specifications and different thread sizes, and the position of the spiral propulsion mechanism 20 in the horizontal and vertical directions is adjusted in cooperation with the lifting assembly 1. It can be correspondingly adapted to the sorting of filter rods of different specifications, achieve better coordination with downstream molding equipment, provide convenience for equipment maintenance, and improve the applicability of the device.
