Description

Technical Field

[0001] This utility model relates to the field of smoke inlet drum technology, specifically to a smoke inlet drum for cigarette rolling equipment. Background Technology

[0002] In the core processes of cigarette production, such as rolling and packaging, the inlet drum is a key component for the continuous and precise delivery of cigarettes (including filter rods). Its main function is to receive cigarettes from upstream processes and stably deliver them to downstream equipment such as loading and cutting machines through grooves distributed circumferentially on its surface, ensuring that the cigarettes are upright and accurately positioned during delivery. The operational stability of the inlet drum directly determines the continuity of cigarette production. If the cigarettes wobble, tilt, or even fall off within the grooves, it will lead to production interruptions, reduced production efficiency, and failure to meet actual usage requirements. Therefore, we have proposed an inlet drum for cigarette equipment to solve the aforementioned problems. Utility Model Content

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figure 1-4 As shown:

[0029] A smoke inlet drum for a cigarette rolling device includes a mounting plate 101;

[0030] The drum body 102 has a hollow structure design and is located on one side of the mounting plate 101. The outer surface of the drum body 102 has multiple sets of arc-shaped grooves arranged in a ring at equal intervals. The drum body 102 has multiple sets of air intake holes 116 located in the arc-shaped grooves.

[0031] The rotating shaft seat 103 is mounted on the mounting plate 101 via a bearing and is located inside the drum body 102, with one end fixedly connected to the drum body 102;

[0032] Two sets of first sealed bearings 104 are embedded in the surface of the rotating shaft seat 103 on both sides;

[0033] Two sets of second sealed bearings 105 are embedded in the inner sidewalls of the drum body 102 on both sides;

[0034] Two sets of annular plates 106 are respectively installed between the inner and outer first sealing bearings 104 and the second sealing bearing 105, and a sleeve 107 is fixedly installed between the two sets of annular plates 106.

[0035] Two sets of partitions 108 are fixedly installed on the surface of sleeve 107. The two sides of the partitions 108 are sealed and fitted with two sets of annular plates 106. A contact plate 110 slides on the partitions 108. A spring 109 arranged symmetrically is fixed between the contact plate 110 and the partitions 108. A moving groove adapted to the contact plate 110 is opened on one side of the partitions 108. The contact plate 110 can slide in the moving groove. The width of the contact plate 110 is adapted to the width of the partitions 108. Both sides are fitted with the two sets of annular plates 106, and the other side is fitted with the inner wall of the drum body 102.

[0036] Among them, the sleeve 107, the two sets of annular plates 106 and the two sets of partitions 108 together form a chamber;

[0037] A vacuum pump 112 is mounted on a mounting plate 101, and a connecting pipe 111 is fixedly mounted on the output end of the vacuum pump 112. One end of the connecting pipe 111 passes through the mounting plate 101 and a set of annular plates 106 and extends into the chamber. The vacuum pump 112 is fixedly connected to the mounting plate 101 through a support plate.

[0038] Two sets of connecting rods 115 are fixed between a set of annular plates 106 and mounting plates 101;

[0039] One of the annular plates 106 is fixedly installed with a one-way air inlet pipe, and one end of the one-way air inlet pipe is located in the cavity.

[0040] Multiple sets of adjustment slots 113 are provided at both ends of the surface of the drum body 102. The two ends of the drum body 102 are provided with symmetrically arranged arc-shaped plates 114. The two sets of arc-shaped plates 114 are fitted together in a ring structure and are locked in a set of adjustment slots 113 at both ends of the surface of the drum body 102. The arc-shaped plates 114 at both ends are locked in the adjustment slots 113 at different positions to achieve the fitting of cigarettes of different lengths.

[0041] In this embodiment: the inlet drum for cigarette equipment, when in use, is formed by the drum body 102, the rotating shaft seat 103, the sleeve 107, two sets of annular plates 106 and two sets of partitions 108 together to form a chamber, and the two sides of the partitions 108 are sealed and fitted with the annular plates 106 to improve the airtightness of the chamber.

[0042] Vacuum pump 112 draws air into the chamber through connecting pipe 111, creating a stable negative pressure inside the chamber. The pressure value can be adjusted by the parameters of vacuum pump 112 to suit different cigarettes. Multiple sets of air intake holes 116 are opened in the arc-shaped groove of drum body 102. The groove and the chamber are connected through the air intake holes 116, so a negative pressure is formed in the groove simultaneously, which firmly adsorbs the cigarette placed in the groove.

[0043] A set of annular plates 106 has a one-way air inlet pipe that supplies external air to the chamber, allowing only air to enter, preventing negative pressure leakage, balancing the air pumping capacity of vacuum pump 112 with the gas consumption in the chamber, avoiding a sudden drop in negative pressure due to gas depletion, and ensuring stable adsorption force.

[0044] When the drum body 102 rotates, the contact plate 110 remains tightly against the inner wall of the drum body 102 under the elastic force of the spring 109, which helps to seal the chamber and reduce negative pressure leakage. For cigarettes of different diameters, such as thin, medium and thick cigarettes, there may be slight differences in the negative pressure adsorption force in the groove. The elastic contact of the contact plate 110 can supplement the radial pressure and prevent the cigarette from moving radially in the groove, especially when the drum body 102 rotates at high speed and generates centrifugal force.

[0045] When the length of the cigarette changes, such as between a standard 84mm cigarette and a 100mm extended cigarette, the two curved plates 114 at both ends can be respectively inserted into the adjusting slots 113 at different positions and locked by screws. By changing the distance between the two sets of curved plates 114, the cigarette length can be adapted. The curved plates 114 fit the surface of the drum body 102 and form a symmetrical ring structure, which does not hinder the rotation of the drum body 102 and can effectively limit the axial sliding of the cigarette to prevent it from falling off.

[0046] The rotating shaft seat 103 is mounted on the mounting plate 101 via bearings, and one end is fixedly connected to the drum body 102. A motor can be installed on one side of the mounting plate 101 to drive the drum body 102 to rotate synchronously with the rotating shaft seat 103, thereby realizing the continuous feeding of cigarettes.

[0047] The first sealed bearing 104 on the surface of the rotating shaft seat 103 and the second sealed bearing 105 on the inner side wall of the drum body 102 are respectively connected to two sets of annular plates 106, ensuring that when the drum body 102 rotates, the chamber formed by the annular plate 106 and the sleeve 107 remains fixed and does not rotate with the drum body 102. The sealed bearing can prevent the negative pressure in the chamber from leaking from the rotation gap, ensuring that the negative pressure system remains effective.

[0048] When the cigarette rotates with the drum body 102 to the point of being misaligned with the chamber, the adsorption force is released, and the cigarette can then be conveyed to other conveying equipment (not shown in the figure).

[0049] This solution uses the uniform negative pressure adsorption of multiple sets of air intake holes 116 to reduce the movement of the cigarette in the groove, ensuring the stability of the cigarette delivery and preventing shaking, tilting or even falling off. At the same time, the cooperation between the arc plate 114 and the adjustment slot 113 can flexibly adjust the axial limit distance to adapt to cigarettes of different lengths, preventing the cigarette from sliding off axially and solving the problem that traditional fixed limiters cannot adapt to multiple specifications.

[0050] It should be noted that all electrical equipment involved in this product is powered by an external power source. The solution also includes an electrical control cabinet, which is installed on the equipment. During use, each piece of electrical equipment can be started and operated separately through the electrical control cabinet. The power connection method of each piece of electrical equipment is an existing mature technology and is well known to those in the field, so it will not be described in detail here.

[0051] Furthermore, any content not described in detail in this specification is prior art known to those skilled in the art.

[0052] The working principle and usage process of this utility model are as follows: In use, the drum body 102, together with the rotating shaft seat 103, sleeve 107, two sets of annular plates 106, and two sets of partitions 108, forms a chamber to ensure airtightness. A vacuum pump 112 draws air into the chamber through a connecting pipe 111, creating a stable negative pressure. The negative pressure value can be adjusted by the vacuum pump 112. Multiple sets of suction holes 116 are opened at the arc-shaped groove of the drum body 102, communicating with the chamber to create negative pressure that adsorbs the cigarette. A one-way air inlet pipe on one set of annular plates 106 replenishes air to the chamber. The vacuum pump 112 balances the pumping volume and chamber gas consumption to maintain stable negative pressure. By adjusting the position of the arc plates 114 at both ends, it can accommodate cigarettes of different lengths, restricting axial sliding of the cigarettes and preventing them from falling off. The rotating shaft seat 103 is mounted on the mounting plate 101 via bearings, driving the drum body 102 to rotate and achieve continuous cigarette delivery. The first sealing bearing 104 and the second sealing bearing 105 connect two sets of annular plates 106 to keep the chamber fixed and prevent negative pressure leakage. When the cigarette rotates with the drum body 102 to the point of being misaligned with the chamber, the adsorption force is released, and the cigarette is delivered to other equipment.

[0053] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
