Description

Technical Field

[0001] This utility model relates to a conveying component, and more particularly to an integrated assembly for conveying filter rods with a self-cleaning function. Background Technology

[0002] Filter rods are an essential component of cigarettes. During cigarette production, cigarette-making machines need to receive filter rods from a filter rod supply system. Current filter rod supply systems consist of a transmitter and a receiver. Due to the height difference between the transmitter and receiver (the transmitter is higher than the receiver), a supply bend is needed to connect them. The receiver includes several conveying units, each connected to a corresponding supply bend. Each conveying unit includes a longitudinal conveying section and a transverse conveying section. The longitudinal conveying section receives the filter rods from the supply bend, while the transverse conveying section changes the conveying direction of the filter rods and feeds them into the cigarette-making machine.

[0003] In actual production, blockages in the filter rod supply chain typically occur at the supply bend and the receiver. When these two parts become blocked, operators need to manually disassemble the supply bend or manually open the receiver's guide rail door to proceed with the cleaning work. This cleaning process is difficult, time-consuming, and severely reduces production efficiency. Utility Model Content

[0004] The purpose of this invention is to overcome the existing defects and provide a filter rod conveying integrated component with self-cleaning function, which solves the problem that the current filter rod supply equipment is difficult to clean and time-consuming, resulting in a decrease in production efficiency when blockage occurs.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A filter rod conveying integrated assembly with self-cleaning function includes a receiver conveying unit and a supply bend. The receiver conveying unit includes a longitudinal conveying component, a transverse conveying component, and a linear guide rail bracket.

The front end of the air supply pipe is connected to the air inlet 14, and the rear end of the air supply pipe is connected to an air inlet connector (not shown in the figure). The air inlet connector is disposed on the rear end face of the housing 6.

[0025] The transverse conveying assembly includes a transverse drive box 15, the right end of which is connected to the left end of the housing 6. A transverse conveying module is arranged on the left side of the transverse drive box 15. The transverse conveying module includes a second wall plate 16 and a third wall plate 17 that are parallel to each other. A second inner guide rail 3 is arranged on the front end face of the transverse drive box 15. The right end of the second inner guide rail 3 extends to the front of the housing 6 and is correspondingly connected to the first inner guide rail 2. Several horizontally collinear conveying roller groups are arranged between the second wall plate 16 and the third wall plate 17. The axial direction of each conveying roller group is the same as that of the second inner guide rail 3. Each conveying roller group includes an upper conveying roller 18 and a lower conveying roller 19. The two ends of the upper conveying roller 18 and the lower conveying roller 19 are rotatably connected to the second wall plate 16 and the third wall plate 17, respectively. The upper conveying roller 18 and the lower conveying roller 19 of the roller assembly are located above and below the axis of the second inner guide rail 3, respectively, and the distance between the upper conveying roller 18 and the lower conveying roller 19 is the same as the outer diameter of the filter rod. The roller shafts of each upper conveying roller 18 and the lower conveying roller 19 pass through the third wall plate 17 and are inserted into the transverse drive box 15. The transverse drive box 15 is equipped with a synchronous gear set, which is connected to each roller shaft to control each upper conveying roller 18 and each lower conveying roller 19 to rotate synchronously in the forward and reverse directions (or the synchronous gear set can contain its own spindle, and the spindle is connected to the roller shaft of each conveying roller using a coupling). The transverse drive box 15 is connected to a servo motor 20 for controlling the rotation of the synchronous gear set. The left end of the second inner guide rail 3 extends to the feeding position of the conveying roller assembly closest to the front end.

[0026] Depending on their location, the outer surface design of the conveyor roller assembly varies. In addition, each conveyor roller has roller grooves on its outer surface to increase friction. Due to the size limitations of the drawing, these grooves would appear as a black blob if shown, so they are deleted from the drawing, but they are actually present.

[0027] On the left side of the third wall panel 17, above and below the second inner guide rail 3, there are fiber optic mounting blocks 21. The two fiber optic mounting blocks 21 are provided with through-fiber optic cables 22 facing the second inner guide rail 3. The through-fiber optic cable 22 is not blocked by the second inner guide rail 3.

[0028] Working principle: A receiver typically has multiple vertically arranged and parallel conveying units. Each feed inlet 8 corresponds to a supply bend. When the through-beam fiber 22 of a conveying unit detects a blockage, it sends a signal to the receiver's controller. The controller first sends a signal to the corresponding transmitter to stop feeding, and then controls the piston rod of the telescopic cylinder corresponding to that conveying unit to extend, driving the push rod 12 to push the linear guide rail bracket 1 and the inverted block 36 outward together. This separates the inverted block 36 from the guide rail plate 35, preventing the filter rod from continuing to be fed to subsequent equipment. Instead, it is fed to the inverted block 36. The filter rod 6 falls freely from the point where it separates from the guide rail plate 35. The blower starts synchronously and blows the filter rods on the first inner guide rail 2 outward through the air outlet 14 (the blowing time is preset according to the actual situation to ensure that all filter rods that may cause blockage in the longitudinal conveying component are effectively discharged). At the same time, the controller controls the servo motor 20 to reverse, and the upper conveying roller 18 and lower conveying roller 19 of each conveying roller group reverse to discharge the filter rods stuck in the conveying roller group (the reversal time is preset according to the actual situation to ensure that all filter rods that may cause blockage in the transverse conveying component are effectively discharged). After the blowing and reversal of the conveying roller group are completed, the controller first controls the blower to stop and the servo motor 20 to resume forward rotation, then controls the piston rod of the telescopic cylinder to retract, driving the top rod 12 to pull the linear guide rail bracket 1 and the inverted block 36 inward together, and finally sends a signal to notify the transmitter to resume feeding.

[0029] A protective cover is provided on the front end face of the first wall panel 9 below the first inner guide rail 2. The protective cover includes an inclined plate 23 extending forward and downward, and a vertical plate 24 extending downward is connected to the outer edge of the inclined plate 23. The function of the protective cover is to guide the cleaned filter rods to fall to the bottom of the receiver during the filter rod cleaning process, so as to prevent them from affecting the conveying unit below.

[0030] The front ends of the second wall panel 16 and the third wall panel 17 are connected to an upper guard plate 25 and a lower guard plate 26. The upper guard plate 25 is located above the second inner guide rail 3, and the lower guard plate 26 is located below the second inner guide rail 3. The function of the upper guard plate 25 and the lower guard plate 26 is to prevent the filter rods cleaned by the upper conveying unit from entering the current conveying roller group and causing blockage during the filter rod cleaning process.

[0031] The discharge guide rail has an arc of 120~150 degrees, which can effectively reduce the probability of clogging compared with the traditional 90 degrees.

[0032] An auxiliary connector 39 is provided at the end of the feed pipe 31 to ensure the stability of the connection between the supply bend and the preceding equipment.

[0033] Two photoelectric switches 40 are installed on the upper side wall of the feed pipe 31, and a reflector (not visible from the viewpoint in the figure) is installed on the lower side wall of the feed pipe 31. The connection between the photoelectric switches 40 and the reflector passes through the feed pipe. A push-pull cylinder 41 is installed on the side wall of the feed pipe 31. The extension rod of the push-pull cylinder 41 is located inside the feed pipe 31 and passes through the feed pipe. When the photoelectric switches 40 detect a blockage in the feed pipe, the extension rod of the push-pull cylinder 41 extends to block the feed pipe, facilitating the cleaning of the supply bend and the receiver conveyor unit.

[0034] This utility model discloses an integrated filter rod conveying assembly with self-cleaning function. It uses a linear guide rail bracket to replace the traditional guide rail door, and designs the end of the supply curve as a split structure consisting of a guide rail plate and a tilting block. After integrating the linear guide rail bracket and the tilting block, its automatic opening and closing is controlled by a cylinder telescopic assembly. Furthermore, a self-cleaning design for the filter rods is added to the conveying unit to replace traditional manual cleaning, which is fast and improves production efficiency.

[0035] 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.
