Abstract
Description
Technical Field
[0001] This utility model relates to the field of cigarette equipment technology, and in particular to an adjustment device and a cigarette rolling machine. Background Technology
[0002] A cigarette rolling machine is a piece of equipment used for automated cigarette rolling, widely used in the tobacco industry. Its main function is to precisely roll tobacco and cigarette paper according to set parameters, improving production efficiency and product consistency. Modern cigarette rolling machines can automatically complete multiple steps such as feeding, rolling, cutting, and packaging, ensuring that the quality and specifications of each cigarette meet standards. During the cigarette rolling process, it is necessary to adjust the floats on both sides of the drum to ensure that the length of the cigarette meets the process standards.
[0003] Currently, the position of the pressure roller is generally adjusted by an adjustment mechanism, causing the pressure roller to press against the float ring, thereby changing the position of the float ring. In existing technology, the adjustment mechanism includes a support shaft, an adjustment screw, and a compression spring. The float ring is movably mounted on the support shaft via a float ring bracket, and the adjustment screw and compression spring are respectively located on both sides of the float ring bracket. By rotating the adjustment screw, the float ring bracket overcomes the elastic force of the compression spring or moves under the drive of the compression spring's elastic force. However, due to prolonged use, tobacco dust easily accumulates on the support shaft, causing the elastic force of the compression spring to be unable to push the float ring bracket after rotating the adjustment screw. The position of the float ring does not change, thus affecting the length of the cigarette. Furthermore, due to slight vibrations during equipment operation, the compression spring also generates high-frequency vibrations, leading to reduced control accuracy of the cigarette length and affecting product quality.

[0030] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0031] like Figures 1-4 As shown, this embodiment provides an adjustment device for adjusting the position of the float 61 that approaches the drum 6.
[0032] The adjustment device includes a support shaft 1, a pressing assembly 2, and an adjustment assembly 3. The pressing assembly 2 is movably mounted on the support shaft 1 along its axial direction. There are two pressing assemblies 2, which are located on both sides of the support shaft 1. The floats 61 on both sides of the drum 6 are located between the two pressing assemblies 2. Thus, after the two pressing assemblies 2 are displaced on the support shaft 1, they can abut against the floats 61 on both sides of the drum 6 to adjust the distance between the two floats 61 and ensure that the length of the cigarette meets the process standards.
[0033] The adjusting component 3 includes an adjusting support 31 and an adjusting rod 32 extending axially. The adjusting support 31 is connected to one end of the support shaft 1. One end of the adjusting rod 32 is rotatably mounted on the adjusting support 31, and the other end of the adjusting rod 32 is threadedly connected to the pressing component 2. There are two adjusting rods 32, and each of the two adjusting rods 32 corresponds to one of the two pressing components 2. Thus, by adjusting one of the two adjusting rods 32, the position of the corresponding pressing component 2 can be directly adjusted. In this process, both pressing components 2 are adjusted by threads, resulting in high adjustment accuracy and high control accuracy of cigarette length. At the same time, the adjusting device will not fail due to the accumulation of dirt on the support shaft 1, nor will it cause fluctuations in cigarette length due to vibration. Therefore, the product quality is high.
[0034] like Figure 2 and Figure 3As shown, the adjusting support 31 includes a support body 311 and a support cover plate 312. The support body 311 and the support cover plate 312 are detachably connected. The support body 311 has a mounting groove 3111 on the side facing the support cover plate 312. The adjusting rod 32 has a stepped portion 321, which is embedded in the mounting groove 3111. One end of the adjusting rod 32 passes through the support cover plate 312, and the other end of the adjusting rod 32 passes through the support body 311 and is threaded to the pressing assembly 2. Thus, by rotating the adjusting rod 32 on one side of the support cover plate 312, the adjusting rod 32 can be rotated as a whole, thereby driving the pressing assembly 2. The adjusting position of the adjusting rod 32 is set outside the support cover plate 312, so the adjusting rod 32 can be adjusted from the outside without being interfered with by the original equipment, thus reducing the difficulty of adjustment. Specifically, the support cover plate 312 is connected to the support body 311 by end screws, and the support cover plate 312 has a countersunk groove, in which the head of the end screw can be embedded. The end of the adjusting rod 32 protruding from the support cover plate 312 has an internal hexagonal groove, so that the adjusting rod 32 can be rotated and adjusted by an internal hexagonal wrench. At the same time, shims are provided on both sides of the step portion 321, and the shims are sleeved on the outside of the adjusting rod 32 to protect the step portion 321 and extend its service life.
[0035] Furthermore, the adjusting assembly 3 also includes a top connector 33. The support body 311 has a threaded hole 3112 radially connected to the mounting groove 3111. The top connector 33 is threaded into the threaded hole 3112 and can abut against the step portion 321. Thus, when the top connector 33 disengages from the step portion 321, the adjusting rod 32 can rotate normally to adjust the position of the adjusting assembly 3. When the top connector 33 abuts against the step portion 321, the adjusting rod 32 is locked and cannot rotate, thereby preventing accidental operation that could cause the adjusting assembly 3 to move and ultimately affect the quality of cigarette production. Optionally, the top connector 33 is an internal hexagon screw.
[0036] like Figure 1 and Figure 2As shown, the pressing assembly 2 includes a movable support 21, a support arm 22, and a pressure roller 23. The movable support 21 is axially movable on the support shaft 1. One end of the support arm 22 is connected to the movable support 21, and the other end is connected to the pressure roller 23. The pressure roller 23 can abut against the float ring 61 that is close to the drum 6. Thus, the support arm 22 allows the movable support 21 and the pressure roller 23 to be spaced apart, thereby ensuring that the support shaft 1 and the adjusting assembly 3 are also spaced apart from the pressure roller 23. This avoids interference between the adjusting device and the existing equipment in a narrow space. Optionally, the support arm 22 is installed on the side of the movable support 21 by connecting screws, and the side of the support arm 22 closest to the support shaft 1 is arc-shaped to avoid obstructing the support shaft 1, thereby facilitating a reduction in the overall size of the adjusting device. Alternatively, the longer adjusting rod 32 is threaded to the one of the two movable supports 21 furthest from the adjusting support 31, and the shorter adjusting rod 32 is threaded to the one of the two movable supports 21 closest to the adjusting support 31. The longer adjusting rod 32 can pass through the one of the two movable supports 21 closest to the adjusting support 31, thereby reducing the distance between the longer adjusting rod 32 and the support shaft 1, and thus reducing the overall size of the adjusting device.
[0037] Specifically, the pressure roller 23 is rotatably mounted on the support arm 22, and the axis of rotation of the pressure roller 23 is parallel to the surface of the float ring 61. This rotation of the pressure roller 23 reduces the difficulty of pressing the float ring 61 against it, ensuring rolling contact between the pressure roller 23 and the surface of the float ring 61, thus preventing friction and wear that could affect adjustment accuracy. Optionally, a bearing is provided at the end of the support, and the pressure roller 23 is rotatably connected to the bearing via a screw. Simultaneously, the support shaft 1 is provided with an axially extending guide member 11, and the movable support 21 has an axially extending guide groove 211. The guide member 11 can be embedded in the guide groove 211, allowing the movable support 21 to move axially on the support shaft 1 without rotating circumferentially, thereby facilitating the adjustment of the position of the pressure roller 23 relative to the float ring 61. Optionally, the guide 11 is a limiting key, and a limiting groove is provided on the support shaft 1. One side of the limiting key is embedded in the limiting groove, and the other side is slidably disposed in the guide groove 211. Of course, the guide 11 can also be integrally formed with the support shaft 1. This embodiment does not make specific limitations.
[0038] like Figure 2 and Figure 4As shown, the adjustment device also includes a mounting bracket 4. The end of the support shaft 1 away from the adjustment component 3 is detachably connected to the mounting bracket 4. The mounting bracket 4 is detachably mounted on the frame of the cigarette machine, thus enabling the adjustment device to be installed on the cigarette machine frame. Optionally, the mounting bracket 4 is connected to the cigarette machine frame by mounting screws. The adjustment device also includes an eccentric support 5, which includes a first mounting hole 51 and a second mounting hole 52. The first mounting hole 51 and the second mounting hole 52 are parallel and not aligned. The end of the support shaft 1 away from the adjustment component 3 is inserted into the first mounting hole 51, and part of the mounting bracket 4 is inserted into the second mounting hole 52. Thus, the eccentric support 5 allows the support shaft 1 and the mounting bracket 4 to be eccentrically positioned, making the support shaft 1, the pressing component 2, and the adjustment component 3 as a whole eccentric relative to the mounting bracket 4, thereby preventing interference between the adjustment device and existing equipment in confined spaces.
[0039] The eccentric support 5 includes a connecting seat 53, a first adjusting part 54, and a second adjusting part 55. The first adjusting part 54 and the connecting seat 53 enclose each other to form a first mounting hole 51, and the second adjusting part 55 and the connecting seat 53 enclose each other to form a second mounting hole 52. One end of the first adjusting part 54 is fixedly connected to the connecting seat 53, and the other end of the first adjusting part 54 is detachably connected to the connecting seat 53 via a first locking screw 56. One end of the second adjusting part 55 is fixedly connected to the connecting seat 53, and the other end of the second adjusting part 55 is detachably connected to the connecting seat 53 via a second locking screw 57. Thus, the first mounting hole 52 can be adjusted via the first locking screw 56. The diameter of the first mounting hole 51 allows the support shaft 1 to be locked or released. The diameter of the second mounting hole 52 can be adjusted by the second locking screw 57, allowing the second mounting hole 52 to lock or release part of the mounting support 4. When the second mounting hole 52 releases part of the mounting support 4, the eccentric support 5 rotates relative to the mounting support 4. Similarly, when the first mounting hole 51 releases the support shaft 1, the support shaft 1 rotates relative to the eccentric support 5, thereby adjusting the contact angle between the adjusting component 3 and the float ring 61, i.e., adjusting the contact angle between the pressure roller 23 and the float ring 61, to meet actual working conditions. Optionally, both the first locking screw 56 and the second locking screw 57 are adjusted from the bottom for easy adjustment by the operator.
[0040] This embodiment also provides a cigarette rolling machine, including the adjustment device as described above. By using the adjustment device as described above, the cigarette rolling machine can adjust the distance between the two float rings 61 to ensure that the length of the cigarette meets the process standard and has high adjustment accuracy. The control accuracy of the cigarette length is high. At the same time, the adjustment device will not fail due to the accumulation of dirt on the support shaft 1, nor will it cause the problem of fluctuating cigarette length due to vibration. Therefore, the product quality is high.
[0041] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
