Description

Technical Field

[0001] This utility model relates to the field of tobacco machinery technology, and in particular to a rod-shaped material conveying drum and slitting equipment. Background Technology

[0002] Cigarette winding and slitting machines are common tobacco machinery. These machines typically use multiple drums to transport and transfer the base rods. Drums in different positions usually have different functions, and are therefore called slitting drums, staggered drums, or combining drums according to their functions. As a type of conveying drum, the combining drum's main function is to adjust the axial position of the base rods, converging two or more staggered rows of base rods into a single row.

[0003] In existing technologies, the combined wheel typically uses negative pressure adsorption to adsorb misaligned base rods into position. Air is drawn in and applied to the suction hole of the drum to achieve axial movement of the base rods pneumatically. At the same time, a stop block is also set in the combined wheel to confirm the position.

[0004] However, negative pressure adsorption has certain limitations and is not suitable for certain types of base rods. For example, in the field of heated cigarettes, the segments of the base rod are relatively short, making it prone to tilting during adsorption and difficult to achieve proper adsorption. Additionally, some heated cigarette base rods have hollow structures (e.g., hollow segments), which cannot be combined using negative pressure adsorption.

[0005] In addition, there is another type of integrated wheel in the existing technology that adopts the structure of cam groove and push rod, but this type of integrated wheel is prone to wear and has low stability. Utility Model Content

This drum utilizes a cam groove and push rod structure to achieve the conveying of rod-shaped materials. The push rod is connected to a slider, which in turn contacts the cam groove wall via a roller.

[0054] This utility model provides a rod-shaped material conveying drum, comprising a fixed part, a rotating part, and a cam pusher mechanism. The rotating part is rotatable relative to the fixed part and includes a drive shaft and a drum body connected to the drive shaft. The outer circumferential surface of the drum body is provided with multiple rod-shaped material receiving grooves. The cam pusher mechanism includes a cam and a slider pusher assembly. The cam is fixedly installed on the fixed part and has an annular cam groove extending circumferentially. The slider pusher assembly is connected to the rotating part and includes a slider and a pusher connected to the slider. The pusher is located in the rod-shaped material receiving groove. The slider is at least partially located in the annular cam groove, and the slider is connected to the groove wall of the annular cam groove via a roller. The slider in the rod-shaped material conveying drum is connected to the groove wall of the annular cam groove via a roller, employing a point-to-line contact rolling friction method, making sliding more flexible, reducing friction with the groove wall, thereby better avoiding slider wear and improving operational stability.

[0055] Please refer to the following: Figures 1 to 5 In one embodiment, a rod-shaped material conveying drum 100 is provided, which is mainly used to adjust the axial position of the rod-shaped material during the conveying process to achieve a combined function.

[0056] The rod-shaped material conveying drum 100 includes a fixed part 10, a rotating part 20, and a cam pusher mechanism 30. The rotating part 20 is rotatable relative to the fixed part 10. The rotating part 20 includes a drive shaft 21 and a drum body 22 connected to the drive shaft 21. The outer peripheral surface of the drum body 22 is provided with multiple rod-shaped material receiving slots 221. The drive shaft 21 is mainly used to connect to a power source, thereby transmitting the power provided by the power source to the drum body 22, driving the drum body 22 to rotate. The drum body 22 is mainly used to receive and convey rod-shaped materials through the rod-shaped material receiving slots 221. Negative pressure adsorption holes or negative pressure adsorption slots can be formed in the rod-shaped material receiving slots 221. A gas distribution seat 40 can be provided on the inner side of the drum body 22. A negative pressure system is used to provide negative pressure in the rod-shaped material receiving slots 221, thereby stably conveying the rod-shaped materials in the form of negative pressure adsorption during the conveying process. This is a well-known technology in the art and will not be elaborated here.

[0057] The cam pusher mechanism 30 includes a cam 31 and a slider pusher assembly 32. The cam 31 is fixedly installed on the fixed part 10. The cam 31 is provided with an annular cam groove 311 extending circumferentially, wherein the annular cam groove 311 refers to a cam groove with an annular structure formed by connecting the ends. Along the axial direction, the annular cam groove 311 has a portion relatively close to the rod-shaped material receiving groove 221 and a portion relatively far away from the rod-shaped material receiving groove 221. Therefore, when the slider pusher assembly 32 slides to different positions in the annular cam groove 311, it can drive the slider pusher assembly 32 to make corresponding linear movements along the axial direction, thereby adjusting the axial position of the rod-shaped material in the rod-shaped material receiving groove 221 and realizing the combined function.

[0058] The slider-push rod assembly 32 is connected to the rotating part 20, so that when the rotating part 20 rotates, it can synchronously drive the slider-push rod assembly 32 to rotate. The slider-push rod assembly 32 includes a slider 321 and a push rod 322 connected to the slider 321. The push rod 322 is located in the rod-shaped material receiving groove 221. The slider 321 is at least partially located in the annular cam groove 311, and the slider 321 is connected to the groove wall of the annular cam groove 311 through a roller 3211. When the rotating part 20 rotates, it synchronously drives the slider push rod assembly 32 to rotate, causing the slider 321 to slide in the annular cam groove 311, thereby changing the position of the slider 321 in the annular cam groove 311. When the slider 321 slides to the part of the annular cam groove 311 that is relatively close to the rod-shaped material receiving groove 221, it will drive the push rod 322 to move towards the center of the rod-shaped material receiving groove 221, thereby pushing the rod-shaped material towards the center of the rod-shaped material receiving groove 221, changing the axial position of the rod-shaped material, and realizing the combined function.

[0059] Understandably, existing merging wheels typically use negative pressure adsorption to achieve merging. However, when the rod-shaped material is short, negative pressure adsorption can easily lead to tilting, making it difficult to adsorb the material properly. Furthermore, when the rod-shaped material is hollow, it can easily deform during adsorption, preventing merging via negative pressure adsorption. Additionally, some existing merging wheels use a cam groove and push rod structure. However, in this type of wheel, the slider is directly placed in the cam groove, and the groove wall and slider have surface contact. The slider slides within the cam groove, resulting in sliding friction, which easily causes wear and reduces stability. Once the slider or cam groove wears down, it affects the push rod's position, impacting the merging effect.

[0060] The rod-shaped material conveying drum 100 provided in this embodiment adopts a cam pusher structure. The pusher 322 directly contacts and pushes the rod-shaped material to achieve its binding. This method is less affected by the structure of the rod-shaped material itself, and can meet the binding requirements for shorter rod-shaped materials, as well as hollow rod-shaped materials. Furthermore, the slider 321 is connected to the groove wall of the annular cam groove 311 via the roller 3211. When the slider 321 slides along the annular cam groove 311, it abuts against the groove wall of the annular cam groove 311 through the roller 3211. The roller 3211 itself rolls, thus changing the original surface contact to point-line contact, and the original sliding friction to rolling friction. This reduces the friction between the groove wall of the annular cam groove 311 and the slider 321, preventing component wear and improving operational stability.

[0061] Preferably, in one embodiment, rollers 3211 are respectively provided on both sides of the slider 321, for example, as shown in the figure. Figure 4 As shown, rollers 3211 are respectively provided on the left and right sides of the slider 321. The rollers 3211 on both sides are connected to the sidewalls 3111 of the annular cam groove 311 on both sides. With this structure, both sides of the slider 321 can be connected and supported in the axial direction, which better avoids wear of the components, and at the same time can drive and position the slider push rod assembly 32 more accurately and stably.

[0062] Preferably, in one embodiment, the cam pusher mechanism 30 is respectively provided on both sides of the drum body 22, for example, as shown in the figure. Figure 1 As shown, the drum body 22 is provided with cam push rod mechanisms 30 on the left and right sides respectively, so that one cam push rod mechanism 30 can push the rod-shaped material located on the left side of the rod-shaped material receiving groove 221 towards the center, and the other cam push rod mechanism 30 can push the rod-shaped material located on the right side of the rod-shaped material receiving groove 221 towards the center.

[0063] Preferably, in one embodiment, each rod-shaped material receiving groove 221 corresponds to only one push rod 322. When a push rod 322 of the cam push rod mechanism 30 located on the right side is provided in a rod-shaped material receiving groove 221, then the push rod 322 of the cam push rod mechanism 30 located on the left side will not be provided in this rod-shaped material receiving groove 221; similarly, when a push rod 322 of the cam push rod mechanism 30 located on the left side is provided in a rod-shaped material receiving groove 221, then the push rod 322 of the cam push rod mechanism 30 located on the right side will not be provided in this rod-shaped material receiving groove 221. That is to say, in this embodiment, each rod-shaped material receiving groove 221 corresponds to only one push rod 322, adopting a single push rod structure, and two push rods are not provided on the left and right sides simultaneously in a rod-shaped material receiving groove 221.

[0064] It is understandable that when push rods are provided on both the left and right sides of a rod-shaped material receiving tank 221, the rod-shaped material will be pushed by both sides when it reaches its final position. However, in actual production, the length of the rod-shaped material is a relatively fluctuating dimension, not a completely constant value. If a structure with push rods on both sides is used, there is a certain risk of squeezing the rod-shaped material, which can easily damage it. By using a single push rod structure, the material can be pushed to the predetermined position according to the stroke, which is stable and accurate, and less likely to cause damage to the rod-shaped material.

[0065] Preferably, in one embodiment, the fixing part 10 includes a mounting base 11 and a protective cylinder 12. The mounting base 11 is connected to the drive shaft 21 via a first bearing 50, thereby providing more stable support for the drive shaft 21. The protective cylinder 12 includes a first protective cylinder 121 and a second protective cylinder 122 axially spaced from the first protective cylinder 121. The second protective cylinder 122 is connected to the first protective cylinder 121 via a connecting bracket 123. The cam 31 of the cam push rod mechanism 30 on one side is fixedly installed inside the first protective cylinder 121, and the cam 31 of the cam push rod mechanism 30 on the other side is fixedly installed inside the second protective cylinder 122. This structure allows for more stable installation and fixing of the cam push rod mechanisms 30 on both sides.

[0066] Specifically, in one embodiment, the mounting base 11 is fixed to the wall panel 200 of the unit equipment with screws. The mounting base 11 is internally connected to the drive shaft 21 via two first bearings 50. The drive shaft 21 is located on one side of the wall panel 200 and connected to a servo motor, which provides power to rotate the drive shaft 21. Elastic retaining rings 51 and washers 52 are respectively provided on both sides of the first bearing 50 located near the wall panel 200. Nuts 53 and first end caps 54 are respectively provided on both sides of the first bearing 50 located away from the wall panel 200. An oil seal 55 is provided inside the first end cap 54.

[0067] Specifically, in one embodiment, the cam 31 is fixedly mounted on the first protective cylinder 121 by screws, the first protective cylinder 121 is fixed on the flange 124 by screws, and the flange 124 is fixed on the cover plate of the wall panel 200 by screws.

[0068] Preferably, in one embodiment, the connecting bracket 123 is located on the outside of the drum body 22, and the connecting bracket 123 and the drum body 22 are spaced apart from each other. By placing the connecting bracket 123 on the outside of the drum body 22, the installation and arrangement of the connecting bracket 123 can be facilitated, and the connecting bracket 123 can also be used as a guide.

[0069] Preferably, in one embodiment, the rod-shaped material conveying drum 100 further includes a guide device 61, a pressure plate 62, and a plastic plate 63. The guide device 61, pressure plate 62, and plastic plate 63 are located outside the drum body 22 and spaced apart from it. The guide device 61 is mainly used to guide the rod-shaped material from the upstream misaligned wheel into the rod-shaped material receiving groove 221 of the rod-shaped material conveying drum 100, and then the rod-shaped material is combined in the area formed by the guide device 61, the plastic plate 63, and the connecting bracket 123.

[0070] Preferably, in one embodiment, the cam 31 located on one side of the second protective cylinder 122 is fixed to the second protective cylinder 122 by a bearing seat 71, and a second bearing 73 is provided between the bearing seat 71 and the connecting block 72 at the end of the drive shaft 21. This structure allows the component to be subjected to more balanced and stable forces, improving operational stability.

[0071] Specifically, in one embodiment, the cam 31 is fixed to the bearing housing 71 by screws, and the bearing housing 71 is fixed to the second protective cylinder 122 by screws. Since the first protective cylinder 121 is fixed, and the second protective cylinder 122 is connected to the first protective cylinder 121 through the connecting bracket 123, the bearing housing 71 is guaranteed not to rotate. The connecting block 72 is connected to the end of the drive shaft 21 away from the servo motor by screws, the inner ring of the second bearing 73 is connected to the connecting block 72, and the outer ring of the second bearing 73 is connected to the bearing housing 71.

[0072] The precise position of the cam 31 is ensured by a corresponding pin, thereby ensuring the consistency of the push rod movement.

[0073] Specifically, in one embodiment, two second bearings 73 are provided, with a spacer sleeve 74 between the two second bearings 73. The inner side of the second bearing 73 located on the inner side is limited by a step on the connecting block 72. The inner and outer rings of the second bearing 73 located on the outer side are fixed by a second end cap 75 and a third end cap 76.

[0074] Preferably, in one embodiment, the slider pusher assembly 32 further includes a connecting module 323, through which the pusher 322 is connected to the slider 321. The connecting module 323 includes a connecting rod 3231 and a connecting seat 3232. The connecting rod 3231 is connected to the slider 321, the connecting seat 3232 is connected to the connecting rod 3231, and the pusher 322 is connected to the connecting seat 3232. This structure allows the slider pusher assembly 32 to push rod-shaped materials more smoothly.

[0075] Preferably, in one embodiment, a plurality of push rods 322 are connected to one of the connecting seats 3232, and each push rod 322 is located in one of the rod-shaped material receiving slots 221. One connecting seat 3232 is connected to the slider 321 via multiple connecting rods 3231. This structure makes the overall arrangement more compact, allowing multiple rod-shaped materials to be pushed with a single movement of the slider push rod assembly 32, while also making the connection between the connecting seat 3232 and the slider 321 more reliable.

[0076] Specifically, in one embodiment, the connecting rod 3231 is fixed to the slider 321 by screws, the connecting seat 3232 is fixed to the connecting rod 3231 by screws, and different numbers of push rods 322 are fixed to the connecting seat 3232 by set screws.

[0077] Preferably, in one embodiment, the rotating part 20 further includes a connecting roller 23, which is connected to the drive shaft 21. The connecting roller 23 has a limiting guide hole 2301 that extends axially through the connecting roller 23, and the connecting rod 3231 passes through the limiting guide hole 2301. By providing the connecting roller 23, the movement position of the connecting rod 3231 can be limited and guided, allowing the slider pusher assembly 32 to push the rod-shaped material more stably and accurately.

[0078] Preferably, in one embodiment, the drum body 22 is connected to the drive shaft 21 via the connecting roller 23. Specifically, in one embodiment, the connecting roller 23 includes a first connecting roller 231 and a second connecting roller 232. The connecting block 72 is connected to the first connecting roller 231 by screws. One side of the drum body 22 is connected to the first connecting roller 231 by screws, and the other side of the drum body 22 is connected to the second connecting roller 232 by screws, thereby achieving the connection of the entire rotating part. When the servo motor drives the drive shaft 21 to rotate, the drum body 22 and the connecting roller 231 can rotate accordingly, thereby driving the connecting rod 3231 to rotate. Consequently, the slider 321 carries the roller 3211 to roll in the cam groove 311, thereby realizing the reciprocating motion of the push rod 322.

[0079] Preferably, in one embodiment, a plurality of slider push rod assemblies 32 are sequentially arranged in one of the cam grooves 311 along the circumferential direction, so as to better adapt to the plurality of rod-shaped material receiving grooves 221 on the drum body 22 and improve the pushing efficiency.

[0080] The position of the push rod 322 can be set according to specific specifications, and the stroke of the push rod 322 can be adjusted by configuring different cams 31.

[0081] Meanwhile, in one embodiment, a slitting device is also provided, which utilizes the rod-shaped material conveying drum 100. Specifically, the rod-shaped material conveying drum 100 is located behind the misalignment wheel. The rod-shaped material, initially several times its length, flows into the misalignment wheel after being slit by the slitting wheel. After the misalignment wheel misaligns the slit rod-shaped material, it is then fed into the rod-shaped material conveying drum 100. The rod-shaped material is then combined by the rod-shaped material conveying drum 100 and sent to the rear slitting wheel for further slitting.

[0082] The above description is merely an embodiment of this utility model. It should be noted that those skilled in the art can make improvements without departing from the inventive concept of this utility model, but these improvements all fall within the protection scope of this utility model.
