Description

Technical Field

[0001] The utility model relates to an online launching and packaging mechanism for automatically supplying cigarette filter rods, in particular to a special tooling for a cigarette filter rod launcher and packaging device packaging mechanism. Background Art

[0002] In cigarette production, the online launch and automatic supply of filter rods is an important process link that is indispensable for modern cigarette production. Frequent failures of the online filter rod launch equipment will seriously restrict the production efficiency of the entire line. Research has found that the unreasonable structural design and material use of the Filtromat-F launcher dispenser used for online filter rod launch are the core reasons for the frequent equipment failures. In order to reduce the failure frequency of the Filtromat-F launcher and improve the online launch efficiency of the equipment, it is urgent to solve the failure problems caused by the unreasonable structural design of the Filtromat-F launcher dispenser.

[0003] The FT-F transmitter dispenser is controlled by opening / closing two states to realize the filling of a certain number of filter rods in the transmitter silo into the launch module "first airlock silo → first airlock opens → filter rods enter the pressure chamber → second airlock opens → launch pressure chamber → launch drum → delivery nozzle → filter rod launch pipeline".

[0004] The existing dispenser is made of flexible material. The biggest advantage of the flexible dispenser is that it can effectively prevent the filter rod from being pinched when the dispenser is closed. However, it also brings the biggest disadvantage: it is easy to age, deform and wear. Due to the aging, deformation and wear of the dispenser, the gap between the dispenser and the silo wall cannot be controlled (see Figure 1 a), which results in problems such as poor filter rod falling and rod clamping during the opening / closing process of the dispenser, and causes the poorly falling filter rod to be clamped at the first airlock gate, resulting in an "upper gate" failure; when the second gate rod of the pressure chamber clamps the rod, a "lower gate" failure occurs; or when the filter rods are messy, horizontally placed, or upright in the launch chamber, the launch drum "horizontally placed horizontal rod" or "drum blocked" failure occurs (see Figure 1 b).

[0005] The existing FT-F transmitter uses a dispenser designed as a flexible "straight plate" dispenser. After the dispenser is opened to discharge the material (see Figure 1 c) During the closing process of the dispenser, the free-falling filter rod is forced to be blocked by the force of the dispenser in the left horizontal direction (see Figure 1 d), and the flexible dispenser sheet is easily deformed, resulting in the filter rod being easily clamped at the dispenser sheet and the filter rod falling vertically from the left side wall of the discharge port when the dispenser is closed (see Figure 1a and e), as well as the abnormal drop of filter rods after the filter rods are divided, which makes the filter rods messy in the first airlock silo, and then causes failures in the subsequent process control process (upper / lower gate, "horizontal horizontal rod" of the ejector drum, "drum obstruction") (see Figure 1 b). Utility Model Content

[0006] The purpose of this utility model is to redesign a specialized tooling for the dispensing mechanism of a cigarette filter rod dispenser.

Preferably, the values ​​of L1, L2, R4, R5, and R6 are 3 mm, 6 mm, 6.05 mm, 5.25 mm, and 3.05 mm, respectively.

[0035] The arc-shaped dispenser piece 2 is in the shape of a horizontal spoon when viewed from the side, wherein the arc surface part 21 is at the spoon head and the connecting plate 22 is at the spoon handle.

[0041] The working principle of this utility model includes:

[0042] The packing mechanism of the present invention is composed of a "throwing guide plate + an arc-shaped packing piece" (see Figure 2 ), whose working principle includes (see Figure 6 ):

[0043] (1) Through the special design of the throwing guide plate, the vertical falling mode of the filter rod on the left side of the original machine is changed, and the "throwing" action of the filter rod on the left side in a parabolic shape is realized;

[0044] (2) Through the special design of the arc-shaped dispenser plate, the original dispenser plate only relies on a force in the left horizontal direction to force the free-falling filter rod to separate and block the process; by forming an "upper left, upward" force on the free-falling filter rod during the closing process of the dispenser plate, the free-falling filter rod is lifted with an "upper left, upward" angle force;

[0045] (3) Under the cooperation of the "throwing guide plate + arc-shaped distributor piece", at the moment the distributor is closed, the semi-circular surface of the "arc-shaped distributor piece" and the semi-circular surface of the "throwing guide plate" coordinate to form a gap of about the diameter of the filter rod end face -0.2mm arc tangent surface, pushing the filter rod at the end to slide upward along the arc surface of the "throwing guide plate + arc-shaped distributor piece", so that the filter rods are better separated and controlled in the material bin above the distributor, solving the problem of filter rods being clamped and sliding down when the distributor is closed, and ensuring that the filter rods are neat and not messy in the first airlock material bin to the greatest extent; thereby reducing the module failure rate (upper / lower gate, launch drum "horizontal horizontal bar", "drum obstruction" failure).

[0046] Furthermore, in order to meet the above installation and adjustment process, the present invention also provides a special installation and adjustment tool 4, such as Figure 7 As shown, its overall shape is similar to the arc-shaped dispenser plate 2, consisting of an arc-shaped head 51 and a connecting rod 51. Its left side is a rectangular block. The arc-shaped head 41 is composed of an inner arc surface and an outer arc surface. The arc line of the inner arc surface is composed of arc MQ near the connecting rod 42 and an extended line segment, and the arc line of the outer arc surface is composed of arc PS. The arc MQ and arc PS are concentric and cocircular, and the arc MQ is tangent to the arc EB of the material throwing guide plate 1.

[0047] The installation and adjustment method of the utility model includes (see Figure 5 ):

[0048] Place the tooling 4 flush with the frame 3, adjust the arc MQ of the tooling 4 to be tangent to the arc EB of the material throwing guide plate 1, tighten the fixing screws between the material throwing guide plate 1 and the frame 3, adjust the gap between the arc-shaped dispenser piece 2 and the tooling 4, so that the arc-shaped dispenser piece 2 and the arc PS of the tooling 4 are just in contact, fix the fixing screws of the arc-shaped dispenser piece 2 and the bracket 3, and remove the tooling 4 to complete the installation.

[0049] Furthermore, the throwing guide plate 1 is kept flush with the frame 3, and the raised portion of the guide plate screw hole 14 of the throwing guide plate 1 is aligned with the fixing screw hole 31 on the frame and roughly installed on the frame 3;

[0050] Furthermore, the distance between the arc-shaped dispenser plate 2 and the throwing guide plate 1 is the diameter of the filter rod end face minus 0.2 mm.

[0051] In order to ensure that the material throwing guide plate 1 and the frame 3 remain horizontal, the arc MQ of the tooling 4 is tangent to the arc EB of the material throwing guide plate; in order to ensure that the distance between the arc-shaped dispenser plate 2 and the material throwing guide plate 1 is the filter rod end face diameter minus 0.2 mm, the thickness of the arc block formed by the arc PS and arc MQ of the tooling 4 is designed to be "the filter rod end face diameter minus 0.2 mm".

[0052] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
