Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of cigarette manufacturing, and in particular relates to a limiting device for a cigarette paper guide. Background Art
[0002] In the tobacco paper rolling process of cigarette manufacturing, a paper guide for guiding the paper is usually provided in the cigarette making machine. The paper guide usually includes a base plate, two mounting plates and limit plates respectively arranged on the two mounting plates. The paper used in the tobacco paper rolling process usually passes through the gap between the limit plates and the mounting plates. In this way, the paper is prevented from twisting, tearing and other abnormal conditions due to uneven force or shaking during the operation of the cigarette making machine.
[0003] In order to facilitate the loading of paper rolls on the machine, the existing paper guide usually leaves a redundant space of about two-thirds of the width of the paper roll between the two limit plates. Since the paper roll is usually mounted on two larger rollers, after passing through the paper guide, there will be multiple paper roll trays of different sizes for paper roll transportation and cigarette rolling. Due to path interference, the paper rolls on the two rollers usually only have the left or right roller in operation. When the paper roll on one side is used up, the rollers on the left and right sides rotate under the drive of the same turntable, so that the other roller on which the new paper roll is mounted is in the working position. During this process, the paper roll tray often undergoes axial movement due to the rotation of the turntable, which may cause the paper roll to twist during the operation of the cigarette making machine, and then fly out of the space between the two limit plates on the paper guide or get stuck. Utility Model Content
[0004] The utility model aims to provide a limiting device for a cigarette paper guide, which is used to solve the problem that the redundant space designed for loading paper on the traditional cigarette making machine paper guide easily causes the paper to fly out or get stuck.
[0005] In order to achieve the above technical purpose, the technical solution adopted by the utility model is as follows:
[0006] A limiting device for a cigarette paper guide, applied to a paper guide of a cigarette making machine, comprises a hollow stopper, and limit blocks respectively arranged on both sides of the stopper and close to the end of the stopper, an adjustment mechanism is arranged in the stopper, the adjustment mechanism comprises an adjustment block, a traction member, and a convergence cavity arranged in the stopper, the adjustment block passes through one end of the stopper and is respectively connected to the limit blocks on both sides of the stopper through the traction member;
[0007] When the adjusting blocks are close to each other, the limiting blocks are gradually converged into the convergence cavity;
[0008] When the adjusting blocks move away from each other, the limiting block extends outward from the convergence cavity.
[0009] In the technical solution, by adjusting the position of the limit block, when the two limit blocks are close to each other, the limit block pulls the traction member, and the traction member pulls the limit block, so that the limit block converges into the convergence cavity, which is convenient for installing the stop block on the paper guide. After the stop block is installed to the ideal position on the paper guide, the position of the limit block is adjusted so that when the two limit blocks are away from each other, the limit block extends outward from the convergence cavity to fix the stop block and prevent the stop block from falling off the paper guide.
[0010] It is further defined that the traction member is a traction rope;
[0011] It is further defined that the adjustment mechanism also includes two first guide posts and two second guide posts arranged in the stopper, the first guide post is arranged at one end close to the adjustment block, the second guide post is arranged at one end close to the convergence cavity, the traction rope passes through the first guide post and the second guide post in sequence and is respectively connected to the adjustment block and the limit block, the inner wall of the convergence cavity is provided with an elastic component, one end of the elastic component is fixedly connected to the inner wall of the convergence cavity, and the other end of the elastic component is fixedly connected to the limit block. Such a structural design changes the force direction of the traction rope through the first guide post and the second guide post, so that when the adjustment block moves, the traction rope provides a pulling force to the limit block and the displacement generated thereby is close to or equal to the displacement of the adjustment block itself, thereby ensuring the effectiveness of the adjustment mechanism, and the structure is simple and has strong practicality.
[0012] It is further defined that the elastic component is a spring.
[0013] It is further defined that the portion of the adjustment block passing through the stopper and located inside the stopper is provided with a limiting protrusion, and a transverse limiting groove is provided on the inner side wall of the stopper, and the limiting protrusion is arranged in the limiting groove. Such a structural design, through the cooperation of the limiting protrusion and the limiting groove, avoids the abnormal situation of the adjustment block being twisted or stuck during the movement, and has a simple structure and strong practicality.
[0014] It is further defined that the two sides of the stopper are provided with limit clamps, and the limit clamps are clamped on the limit plates of the paper guide. Such a structural design can avoid the installation stability of the stopper on the paper guide through the limit clamps, and will not hinder the removal of the stopper, and has a simple structure and strong practicality.
[0015] The utility model adopting the above technical solution has the following advantages:
[0016] 1. The utility model adjusts the position of the limit block so that when the two limit blocks are close to each other, the limit block pulls the traction member, and the traction member pulls the limit block so that the limit block converges into the convergence cavity, which is convenient for installing the stop block on the paper guide. After the stop block is installed to the ideal position on the paper guide, the position of the limit block is adjusted so that when the two limit blocks are away from each other, the limit block extends outward from the convergence cavity to fix the stop block and prevent the stop block from falling off the paper guide.

[0028] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that in the drawings or in the specification, similar or identical parts use the same figure numbers, and the implementation methods not shown or described in the drawings are forms known to ordinary technicians in the relevant technical field. In addition, the directional terms mentioned in the embodiments, such as "upper", "lower", "top", "bottom", "left", "right", "front", "back", etc., are only referenced to the directions of the drawings and are not used to limit the scope of protection of the present invention.
[0029] like Figure 1 to Figure 4 As shown, a limiting device for a cigarette paper guide of the utility model is applied to a paper guide 1 of a cigarette making machine. The paper guide 1 comprises a bottom plate 101, two mounting plates and limiting plates 102 respectively arranged on the two mounting plates.
[0030] The limiting device for the cigarette paper guide comprises a hollow block 2, and limiting blocks 3 respectively arranged on both sides of the block 2 and close to the end of the block 2, an adjustment mechanism is arranged in the block 2, and the adjustment mechanism comprises an adjustment block 401, a traction rope 402, and a convergence cavity 403 arranged in the block 2, the adjustment block 401 passes through one end of the block 2 and is respectively connected to the limiting blocks 3 on both sides of the block 2 through the traction rope 402;
[0031] When the adjusting blocks 401 are close to each other, the limiting block 3 is gradually converged into the convergence cavity 403;
[0032] When the adjusting blocks 401 move away from each other, the limiting block 3 extends outward from the convergence cavity 403 .
[0033] In the present technical solution, by adjusting the position of the limit block 3, when the two limit blocks 3 are close to each other, the limit block 3 pulls the traction rope 402, and the limit block 3 is pulled by the traction rope 402, so that the limit block 3 converges into the convergence cavity 403, which is convenient for installing the stopper 2 on the paper guide 1. After the stopper 2 is installed to the ideal position on the paper guide 1, the position of the limit block 3 is adjusted so that when the two limit blocks 3 are away from each other, the limit block 3 extends outward from the convergence cavity 403 to fix the stopper 2 and prevent the stopper 2 from falling off the paper guide 1.
[0034] In an optional embodiment, the adjustment mechanism further includes two first guide posts 404 and two second guide posts 405 disposed in the stopper 2, the first guide post 404 being disposed at one end close to the adjustment block 401, the second guide post 405 being disposed at one end close to the convergence cavity 403, and the traction rope 402 bypasses the first guide post 404 and the second guide post 405 in sequence and is connected to the adjustment block 401 and the limit block 3 respectively. Among them, the traction rope 402 connected to the left adjustment block 401 first bypasses the left side of the first guide post 404 on the left, then bypasses the right side of the second guide post 405 on the left, and then connects to the limit block 3 on the left; the traction rope 402 connected to the right adjustment block 401 first bypasses the right side of the first guide post 404 on the right, then bypasses the left side of the second guide post 405 on the right, and then connects to the limit block 3 on the right. The inner wall of the convergence cavity 403 is provided with a spring 406, one end of the spring 406 is fixedly connected to the inner wall of the convergence cavity 403, and the other end of the spring 406 is fixedly connected to the limit block 3. With such a structural design, the force direction of the traction rope 402 is changed by the first guide column 404 and the second guide column 405, so that when the adjustment block 401 moves, the traction rope 402 provides a pulling force to the limit block 3, and the displacement generated thereby is close to or equal to the displacement of the adjustment block 401 itself, thereby ensuring the effectiveness of the adjustment mechanism, and having a simple structure and strong practicality.
[0035] In an optional embodiment, the portion of the adjusting block 401 passing through the stopper 2 and located inside the stopper 2 is provided with a limiting protrusion 5, and a transverse limiting groove 6 is provided on the inner side wall of the stopper 2, and the limiting protrusion 5 is arranged in the limiting groove 6. Such a structural design, through the cooperation of the limiting protrusion 5 and the limiting groove 6, avoids the abnormal situation of the adjusting block 401 being twisted or stuck during the movement, and the structure is simple and has strong practicality. Among them, the portion of the adjusting block 401 located outside the stopper 2 can be a rectangular handle or an L-shaped handle, and the rectangular handle has a wider contact area, which is convenient for the user to operate the adjusting block 401, and the L-shaped handle has a similar effect as the limiting block 3, that is, preventing the stopper 2 from falling off the paper guide 1. Under the action of the L-shaped handle and the limiting block 3, the stopper 2 is inserted and installed from the upper part or the lower part of the paper guide 1, and will not fall off the paper guide 1 under the action of gravity. The portion of the adjusting block 401 located outside the stopper 2 is not specifically limited here.
[0036] In an optional embodiment, the two sides of the stopper 2 are further provided with limit clamps 7, and the limit clamps 7 are clamped on the limit plates 102 of the paper guide 1. Such a structural design avoids the installation stability of the stopper 2 on the paper guide 1 through the limit clamps 7, and does not hinder the removal of the stopper 2, and has a simple structure and strong practicality.
[0037] When the limiting device for the cigarette paper guide provided in this embodiment is used, the adjusting block 401 is first adjusted so that the two adjusting blocks 401 are in a moving state approaching each other, so that the limiting block 3 is pulled by the two adjusting blocks 401 and the traction rope 402 respectively connected to the adjusting block 401 and the limiting block 3, so that the limiting block 3 converges into the convergence cavity 403; then, the convergence state of the limiting block 3 is maintained, and the stopper 2 is pushed upward from bottom to top, passing through the redundant space between the two limit plates 102 of the paper guide 1, and clamped on the limiter block 3 of the paper guide 1 by the limit clamping plate 7 on the side of the stopper 2. When the stopper 2 is pushed to the ideal position, the adjusting block 401 is released, and the limiter block 3 extends outward from the convergence cavity 403 under the action of the spring 406 and returns to its original position, so as to limit the installation position of the stopper 2 and prevent it from falling from the paper guide 1.
[0038] The above is a detailed introduction to a limiting device for a cigarette paper guide provided by the utility model. The description of the specific embodiment is only used to help understand the method and core idea of the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
