Description

Technical Field

[0001] This utility model relates to the field of cigarette equipment technology, specifically to a filter tip acceleration wheel with an end-face air distribution and suction structure. Background Technology

[0002] The filter rod supply system consists of a filter rod hopper, a filter rod cutting drum, a staggered drum, a straightening drum, and an accelerating drum. Under negative pressure, the filter rod cutting drum receives filter rods from the filter rod hopper, aligns the filter rods axially, and cuts them into filter tips of equal length. The filter tips are then fed to the staggered drum. The staggered drum arranges the three filter tips from one groove of the filter rod cutting drum in a staggered manner, placing them in three different grooves. The straightening drum gathers the three staggered filter tips into a row. The accelerating drum aligns the filter tips along the center of the accelerating drum and accelerates them, feeding them to the converging drum at the same linear velocity to synchronize with the cigarette delivery.

[0003] Chinese patent publication reveals a novel cigarette dispenser mouthpiece transmission mechanism (application number: 202020544894.1), which discloses a cylindrical air distribution drum located between an acceleration wheel and a rotating shaft. The acceleration wheel has a ventilation hole at the bottom of its toothed groove, and the air distribution drum has a negative pressure channel along its circumference, with the ventilation hole connected to the negative pressure channel.

[0004] The original equipment lacked negative pressure suction in the acceleration wheel groove, relying instead on the interaction between the drum wheel groove and multiple guide rails to accelerate and transport the filter rod. These guide rails constrained and positioned the filter rod axially, vertically, and horizontally. During adjustment, the guide rail positions affected each other, making it difficult to adjust each rail to its ideal position individually. Even after adjustment, the thin-plate structure of the guide rails made them susceptible to wear from the high-speed filter rod, necessitating periodic precision adjustments to the gaps between the guide rails. Improper guide rail positioning or wear could cause equipment malfunctions such as filter rod loss, drum wheel cigarette dropping, and clogging of the rubbing plate, resulting in cigarette quality issues at the splicing and joining points.

[0005] Therefore, it is necessary to propose a filter nozzle acceleration wheel with an end-face air distribution and suction structure to address the above-mentioned technical problems. Utility Model Content

[0006] The purpose of this invention is to provide a filter nozzle acceleration wheel with an end-face air distribution and suction structure to solve the above-mentioned technical problems.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A filter nozzle acceleration wheel with an end-face air distribution and suction structure includes an acceleration wheel, a negative pressure distribution valve, a wall plate, and a suction zone. The negative pressure distribution valve is installed on the side of the wall plate. The acceleration wheel is connected to the negative pressure distribution valve. The suction zone is connected to the negative pressure air path inside the negative pressure distribution valve. The circumference of the acceleration wheel is provided with a plurality of annularly distributed suction holes.

[0009] Preferably, the air intake holes are provided with twelve.

[0010] Furthermore, the inner end face of the acceleration wheel with twelve suction holes is provided with a 0.05mm gap from the outer end face of the suction area. This is to prevent the two contact surfaces from interfering and scraping due to heat generation, so as not to affect the relative motion, and to enable the negative pressure inside the negative pressure distribution valve to be supplied to the acceleration wheel.

[0011] Preferably, the wall panel is provided with a negative pressure opening, which is connected to the air intake zone.

[0012] Preferably, an adjustment pad is provided between the air suction zone and the wall panel.

[0013] Preferably, the air intake area is provided with a cover plate.

[0014] Preferably, the wall panel is connected to a filter tip guide rail. The function of the filter tip guide rail is to scoop the filter tip rod out of the groove of the preceding straight drum, and after scooping it out, continue to keep the filter tip rod slightly pressed. Under the combined action of adsorption force, the filter tip rod can be stably attached to the surface of the acceleration wheel, avoiding the phenomenon of filter tip tilting or falling off due to centrifugal force and other factors.

[0015] This utility model offers the following advantages: Through low-cost modification, it transforms the filter tip acceleration wheel into a structure with suction, while reducing the number of filter tip guide rails to two. This improves filter tip supply stability, reduces maintenance and adjustment difficulty, and enhances the equipment's ability to guarantee product quality. It also avoids numerous customer complaints regarding substandard cigarettes with double-length filters at all ends due to the filter tip stick falling off, and reduces secondary quality problems such as cigarette ejection from the drum wheel and water-soaked paper scraps sticking to the washboard caused by the filter tip stick falling off.

[0023] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered by the claims.

[0024] The following is in conjunction with the appendix Figure 1-5 The embodiments of this utility model will be described in further detail.

[0025] This embodiment provides a technical solution:

[0026] A filter nozzle acceleration wheel with an end-face air distribution and suction structure includes an acceleration wheel 1, a negative pressure distribution valve 4, a wall plate 5, and a suction zone. The negative pressure distribution valve 4 is installed on the side of the wall plate 5. The acceleration wheel 1 is connected to the negative pressure distribution valve 4. The suction zone 9 is connected to the negative pressure air passage inside the negative pressure distribution valve 4. The circumference of the acceleration wheel 1 is provided with twelve annularly distributed suction holes 2.

[0027] The suction zone 9 is connected to the negative pressure air path inside the negative pressure distribution valve 4. Because the inner end face of the twelve suction holes 2 of the acceleration wheel 1 is in high-speed relative motion with the outer end face of the suction zone 9, in order to prevent the two contact surfaces from interfering and scraping due to the heat of the equipment, a gap of 0.05mm is set between the inner end face of the twelve suction holes 2 of the acceleration wheel 1 and the outer end face of the suction zone 9. This does not affect the relative motion, but also enables the negative pressure inside the negative pressure distribution valve 4 to be supplied to the acceleration wheel 1.

[0028] The wall panel 5 is provided with a negative pressure opening 6, which is connected to the air suction zone 9.

[0029] An adjusting pad 7 is provided between the air intake zone 9 and the wall panel 5. The adjusting pad 7 serves to seal and absorb shock.

[0030] The air intake zone 9 is equipped with a cover plate 8.

[0031] The wall panel 5 is connected to the filter guide rail 3.

[0032] The filter guide rail 3 serves two purposes: firstly, it removes the filter rod from the groove of the straightening drum in the previous sequence; secondly, it continues to keep the filter rod slightly pressed after removal; and thirdly, under the combined action of adsorption force, the filter rod can be firmly attached to the surface of the acceleration wheel 1, thus avoiding the phenomenon of filter tip tilting or falling off due to centrifugal force and other factors.

[0033] This utility model achieves a low-cost modification by changing the filter tip acceleration wheel to a structure with suction, while reducing the filter tip guide rails 3 to two, thereby improving the stability of filter tip supply, reducing the difficulty of maintenance and adjustment, enhancing the equipment's ability to guarantee product quality, avoiding multiple customer complaints about substandard cigarettes with double-length filters at all ends due to the filter tip stick falling off, and reducing secondary quality problems such as the drum wheel throwing smoke and the washboard sticking with water and loose paper pieces caused by the filter tip stick falling off.

[0034] Working principle: When the acceleration wheel 1 rotates, the negative pressure distribution valve 4 draws out the air from the acceleration wheel 1 through the suction channel, creating a negative pressure environment around the filter rod located in the clamping space, thereby adsorbing the filter rod onto the clamping part; under the action of adsorption force, the filter rod can be firmly attached to the surface of the acceleration wheel 1, and is smoothly accelerated and conveyed as the acceleration wheel 1 rotates, avoiding the phenomenon of filter tip tilting or falling off due to centrifugal force and other factors, ensuring the stability and accuracy of filter tip conveying, and finally accurately sending the filter tip to the next process such as the converging drum.

[0035] Twelve suction holes 2 are evenly distributed on the inner end face of the acceleration wheel 1. Then, suction holes 2 are drilled in each adsorption groove of the acceleration wheel 1 to communicate with it. The end face of the acceleration wheel 1 is connected to the negative pressure distribution valve 4. The number of filter guide rails 3 is reduced to two, and the excess is removed to increase the installation space of the negative pressure distribution valve 4. A negative pressure opening 6 is provided at the wall plate 5 corresponding to the base plate of the filter guide rail 3 to provide negative pressure suction for the negative pressure distribution valve 4.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
