Description

Technical Field

[0001] The utility model relates to the technical field of cigarette production auxiliary equipment, in particular to a falling conveying channel device of a filter rod unloading machine. Background Art

[0002] Filter rods, also known as filter tips, are components attached to cigarettes. Their primary function is to reduce the amount of harmful substances inhaled into the body through physical filtration during smoking. Currently, in cigarette production, filter rods are produced by forming machines, loaded onto trays by tray loading machines, and transported to a finished filter rod warehouse for storage. When filter rods are needed for the cigarette making process, the trays are unloaded by tray unloaders and transported to a dispenser, which then delivers them to the corresponding cigarette making machine. The process involves lifting the tray, rotating it, and unloading the filter rods. However, during the tray rotation process, the filter rods naturally fall due to gravity. Due to the wide discharge opening and lack of drainage and diversion, the falling filter rods can easily become tangled, resulting in horizontal sticks. This can clog the dispenser in the downstream machine, leading to a filter rod supply shortage and seriously impacting production demand. Summary of the Invention

[0003] To address the problem of poor conveying smoothness in existing conveying channels, which easily causes sticks to be sideways and thus leads to interruption of filter rod flow, a new filter rod dropping channel device is proposed. This device can divert filter rods for conveying after unloading the filter rod tray, avoiding surface damage caused by filter rod accumulation and preventing sideways mouth phenomenon during conveying.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0026] A filter rod unloading machine falling conveying channel device, such as Figures 1 to 7As shown, it includes a conveying channel body, which is provided with a conveying channel 1 with a rectangular cavity structure; a filter rod inlet 101 is provided at the top of the conveying channel body, and in this embodiment, the filter rod inlet is rectangular; a filter rod conveying device is provided at the bottom of the conveying channel 1, which is a conveyor belt 104 in this embodiment; the filter rod falls from the top of the conveying channel, and baffles are provided around it to prevent the filter rod from falling. After the filter rod falls onto the conveyor belt, it is conveyed to the right. An output channel opening 5 is provided at the lower right portion of the conveying channel 1. A guide block 2 is provided within the conveying channel 1. The guide block 2 is provided below the filter rod inlet. In this embodiment, the guide block 2 is provided in the middle of the conveying channel 1. Two guide blocks 2 are provided, including a left guide block 201 and a right guide block 202. The right guide block 202 is smaller than the left guide block 201 because filter rods are transported and accumulated from the left to the right. Therefore, the bottom position of the right guide block 202 is relatively higher. The upper portion of the guide block 2 is provided with a left inclined surface and a right inclined surface, and the lower portion is provided with a right curved surface. The guide block 2 has the following functions: 1. It diverts the filter rod flow during the conveying process, dividing the filter rod flow into three parts, making the filter rod flow conveying smoother and more efficient. 2. It reduces the pressure on the lower filter rods during the falling process.

[0027] It also includes a diverter plate 3, which is an arc-shaped structure. The diverter plate 3 is arranged on the left and right sides of the guide block 2 and is used to further rectify the filter rod flow divided by the guide block 2.

[0028] Optionally, in this embodiment, a left slope 102 and a right slope 103 are provided on the left and right sides of the conveying channel 1, respectively. The diverter plates 3 are combined into a group with two intervals, and a group of diverter plates is provided on the same side of the guide block. A first group of diverter plates is provided between the left slope and the guide block; a second group of diverter plates is provided between the right slope and the guide block. A third group of diverter plates is provided between the two guide blocks 2. That is, a total of six diverter plates are fixed in the conveying channel 1, including a first diverter plate 301, a second diverter plate 302, a third diverter plate 303, a fourth diverter plate 304, a fifth diverter plate 305, and a sixth diverter plate 306, all of which are arc-shaped structures, and their ends are chamfered at 45° to facilitate the sliding of filter rods. Its function is to further divert the filter rod flow divided by the guide block. The distance between the two diverter plates can just accommodate three filter rods to pass through, so that the filter rods are transported in an orderly manner, thereby reducing the generation of cross-mouth filter rods.

[0029] When producing filter rods of different models, in order to improve the efficiency of filter rod diversion and transportation and reduce the generation of horizontal rods, the diverter plate 3 can be disassembled and replaced with a diverter plate of corresponding size. The gap of the diverter plate can be adjusted according to the size of the filter rod, and then fixed with bolts to complete the replacement of the diverter plate. This design is quick and convenient and effectively improves the versatility of the falling channel.

[0030] Optionally, the bottom positions of the first group of diverter plates are the shortest distance from the filter rod conveying device; and the bottom positions of the second group of diverter plates are the furthest distance from the filter rod conveying device.

[0031] Optionally, it also includes a front protective baffle assembly 4, which is arranged at the front of the device and is fixed to the front end of the equipment by a hinge 402, so as to prevent the filter rod from falling forward; the front protective baffle assembly 4 includes a front glass baffle 401, a hinge 402, and a handle 403; the front glass baffle 401 is connected to the conveying channel body by a hinge 402, and is naturally fixed at the front protective baffle by gravity, so as to prevent the filter rod from falling forward; the hinge is located on the left and right sides of the conveying channel, and is used to fix the front glass baffle on the conveying channel, and when necessary, the glass plate can be rotated upward to take the filter rod; the handle is located below the front glass baffle, and if you want to open the front glass baffle, you can use the handle to flip the front glass baffle upward.

[0032] In this embodiment, the outlet channel 5 is located on the lower right side of the drop channel and serves as the interface between the drop channel and the filter rod launcher. The channel is rectangular and has a protective belt 501 installed above to protect the filter rods from impact during transport. A conveyor belt 502 is installed below to transport the filter rods in the drop channel to the filter rod launcher at the filter rod outlet 503.

[0033] It also includes an output channel baffle assembly 6, which is arranged in front of the output channel opening 5 and is fixed to the front end of the equipment by a hinge 602, so as to prevent the filter rod from falling forward in the conveying channel; the output channel baffle assembly 6 includes an output channel glass baffle 601, a hinge 602, and a handle 603; the output channel glass baffle is connected to the output channel by a hinge and is naturally fixed at the output channel by gravity, so as to prevent the filter rod from falling forward during the conveying process of the output channel; the hinge is located on the left and right sides of the output channel, and is used to fix the output channel glass baffle on the output channel opening 5, and when necessary, the glass plate can be rotated upward to take the filter rod in the output channel.

[0034] In order to reduce the number of machine stoppages and improve the efficiency of filter rod delivery, if a filter rod becomes stuck during delivery through the delivery channel or the delivery port becomes clogged, the delivery channel baffle 6 can be opened and the output channel glass baffle 601 can be lifted upward using the handle 603. The output channel glass baffle can be rotated around the hinge within a wide range of angles, making it easier for the operator to handle the filter rod in the delivery channel in a timely manner, effectively reducing the number of machine stoppages.
