Description

Technical Field

[0001] The present invention belongs to the technical field of cigarette production equipment. Specifically, it relates to a tipping paper guide rail structure that can be quickly replaced and adjusted mechanically. Background Art

[0002] The production and operation speed of a tipping machine is fast, and the process quality requirements are high. During production, downtime and quality losses should be minimized as much as possible. A tipping machine often undertakes the production of several brands or specifications of cigarettes, and there are often situations where cigarettes need to be changed frequently. When the width specifications of the tipping paper used for different brands of cigarettes are different, the tipping paper guide rail needs to be replaced correspondingly. Referring to the attached Figure 1 As shown, the guide rail assembly equipped on the existing cigarette machine is designed into two parts, the inner and the outer, with a complex structure. The two guide rail parts (12, 13) are respectively provided with a rib and a working surface. When there are manufacturing or installation deviations between the inner and outer guide rail parts (12, 13), there are shape deviations between the inner and outer working surfaces, which will cause scratches on the tipping paper. When changing the specifications, all components must be disassembled and disassembled, which is time-consuming and laborious, increases the cigarette change time, and also increases the waste of defective products during the repeated debugging process after changing the cigarette. The labor intensity of operation and maintenance is relatively large, and the proportion of ineffective time used for auxiliary preparation increases.

[0003] In addition, during the production and operation of the tipping machine, many reasons such as differences in the inner diameter of the paper reel and the winding tightness of the web paper will cause the tipping paper to run off. The linear speed of the tipping paper exceeds 2 m / s, and it often deviates from the center line, resulting in inconsistent lengths of the tipping paper for the inner and outer rows of cigarettes. In severe cases, it will cause the defect that the wrapping length deviation of the tipping paper exceeds the standard. When the length deviation of the tipping paper for the inner and outer rows of cigarettes exceeds the standard, the operator has to shut down the equipment and open the large protective cover of the tipping machine before manually rotating the adjustment shaft (11) on one side of the tipping paper guide rail part to move the center line of the guide rail part (12, 13) inward or outward. The manual rotation amplitude can only be carried out based on experience, and it is difficult to quickly and accurately adjust to the ideal position. It is necessary to repeatedly shut down the equipment and open the large protective cover for fine adjustment. The faster the equipment runs, the wider the tipping paper is, the more frequent and serious the running-off phenomenon is, and the more frequent the adjustment of the guide rail center line for deviation correction is required. Frequent shutdowns reduce the effective operation rate of the equipment and are also not conducive to the improvement of the cigarette quality. Summary of the Invention

[0004] The embodiment of the present invention provides a tipping paper guide rail structure that can be quickly replaced and adjusted mechanically, aiming to solve the problems of difficult disassembly and assembly of the existing tipping paper guide rail block of the tipping machine and troublesome adjustment of the center line of the tipping paper.

The surface of the guide rail block is arc-shaped, and limiting bumps are symmetrically arranged on both sides of the surface of the guide rail block. The area between the two limiting bumps on both sides is the working surface of the guide rail block. An assembly groove is opened at the bottom of the guide rail block, and the assembly groove is in a "U" shape. The guide rail block is placed on the surface of the sliding sleeve through the assembly groove. Outer limiting blocks and inner limiting blocks are symmetrically arranged at both ends of the guide rail block. The shapes of the outer limiting blocks and the inner limiting blocks are both adapted to the shape of the guide rail block. A first through hole is opened on the outer limiting block, and a second through hole is opened on the inner limiting block. The outer limiting blocks and the inner limiting blocks are respectively assembled to the surface of the sliding sleeve through the first through hole and the second through hole. The flexible component includes a fixing plate and a speed reducer. The fixing plate is fixedly connected to the outer machine frame by bolts, and the speed reducer is arranged on one side of the fixing plate.

[0007] As a preferred technical solution of the present invention, a driving gear and a driven gear are arranged on the side of the fixing plate away from the speed reducer. The output shaft of the speed reducer penetrates through the fixing plate and is fixedly connected to the center of the driving gear. The driven gear meshes with the driving gear. One end of the fixed section away from the telescopic section penetrates through the machine frame and is fixedly connected to the center of the driven gear.

[0008] As a preferred technical solution of the present invention, the outer surface of the fixed section is in sliding contact with the inner wall of the telescopic blind groove. Four transmission columns are symmetrically arranged at the end of the fixed section. The central axis of the transmission column is perpendicular to the central axis of the fixed section. Four limiting grooves are symmetrically opened on the inner wall of the telescopic blind groove, and the transmission column is slidably arranged inside the limiting groove.

[0009] As a preferred technical solution of the present invention, a spring member and a washer are sleeved on the support shaft. One side of the washer abuts against the side wall of the inner limit block. One end of the spring member abuts against the side wall of the washer. The inner diameter of the sliding sleeve is adapted to the outer diameter of the support shaft. A guide groove is formed in one end of the support shaft close to the lead screw shaft along the central axis extension direction. A guide key is arranged on the inner surface of the sliding sleeve, and the guide key is slidably arranged inside the guide groove.

[0010] As a preferred technical solution of the present invention, one end of the sliding sleeve abuts against the side wall of the washer, a retaining ring is arranged at the other end of the sliding sleeve, the diameter of the retaining ring is equal to the diameter of the sliding sleeve, and one side of the retaining ring abuts against the end of the telescopic section.

[0011] As a preferred technical solution of the present invention, glue accumulation grooves are formed on both sides of the working surface close to the side positions of the limit bumps, and a relief inclined surface is formed on one side of the assembly groove.

[0012] As a preferred technical solution of the present invention, a first connecting bolt is arranged on one side of the outer limit block. After passing through the outer limit block, the first connecting bolt is threadedly connected to the side wall of the guide rail block. A first fastening bolt is arranged at the bottom of the outer limit block. The first fastening bolt penetrates into the first through hole and abuts against the outer surface of the sliding sleeve.

[0013] As a preferred technical solution of the present invention, a positioning groove is formed at the top of the inner limit block. The positioning groove has a "U" - shaped structure. A second connecting bolt is arranged on one side of the inner limit block. After passing through the positioning groove, the second connecting bolt is threadedly connected to the side wall of the guide rail block. A second fastening bolt is arranged at the bottom of the inner limit block. The second fastening bolt penetrates into the second through hole and abuts against the outer surface of the sliding sleeve.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] (1) During the installation of this structure, the assembly groove at the bottom of the guide rail block is inserted centrally between the inner limit block and the outer limit block, so that the guide rail block is assembled onto the sliding sleeve. Then, the guide rail block is connected to the inner limit block and the outer limit block through connecting bolts. The guide rail block is thus positioned on the sliding sleeve. The center line of the newly installed guide rail block remains unchanged, reducing the number of centering and debugging times, simplifying the replacement and disassembly steps of guide rail blocks of different specifications, realizing the quick replacement of the tipping paper guide rail block to meet the rapid cigarette - changing requirements, changing the existing components and replacement methods, eliminating the time and material waste caused by repeated adjustment due to specification replacement, reducing the downtime and output loss caused by the large adjustment difficulty and long time consumption, greatly improving the adjustment accuracy, being beneficial to improving the production efficiency of the workshop, reducing the labor intensity of maintenance and operation personnel, and enhancing the production guarantee level of the equipment;

[0016] (2) The speed reducer drives the rotation of the lead screw shaft through the meshing of gears. The threaded fit between the lead screw shaft and the support shaft causes the lead screw shaft to push the sliding sleeve inward or outward during forward and reverse rotations, thereby moving the position of the guide rail block to adjust the center line of the tipping paper to the position meeting the process quality requirements. By driving the speed reducer, the center line of the tipping paper can be adjusted without stopping the machine, with high automation, fast and accurate adjustment, reduced frequent stops, and effectively ensuring production efficiency and finished product quality.

[0017] The above description is only an overview of the technical solution of the present invention. In order to understand the technical means of the present invention more clearly, it can be implemented according to the content of the specification. And in order to make the above and other purposes, features and advantages of the present invention more obvious and understandable, the specific embodiments of the present invention are hereinafter specifically exemplified.

[0029] Refer to the attached Figures 2 - 5As shown in the figure, the present invention provides a technical solution: a tipping paper guide rail structure capable of quick replacement and flexible adjustment, including a machine frame 101, a lead screw shaft 102, a support shaft 103, a sliding sleeve 104, a guide rail block 105 and a flexible component 108. The lead screw shaft 102, the support shaft 103 and the sliding sleeve 104 are all arranged coaxially at the center and are all arranged between the machine frames 101. This structure improves the original structure in the machine frame 101, which is complex in structure and troublesome to disassemble. One end of the support shaft 103 is fixedly connected to the inner machine frame 101 by threads. The support shaft 103 plays a role in positioning and supporting the guide rail block 105. A threaded hole 1034 is opened on the end surface of the other end of the support shaft 103. The lead screw shaft 102 includes a fixed section 1021 and a telescopic section 1023. One end of the telescopic section 1023 is provided with a threaded post 1024, and the threaded post 1024 is connected with the threaded hole 1034 in a matching manner. The other end of the telescopic section 1023 is provided with a telescopic blind groove 1025. One end of the fixed section 1021 is embedded in the interior of the telescopic blind groove 1025. The sliding sleeve 104 is sleeved on the support shaft 103. The lead screw shaft 102 adjusts the left and right positions of the sliding sleeve 104 through threaded cooperation with the support shaft 103, so as to realize the adjustment of the tipping paper center line on the guide rail block 105. The surface of the guide rail block 105 is arranged in an arc shape. Limiting convex blocks 1051 are symmetrically arranged on both sides of the surface of the guide rail block 105. The area between the two limiting convex blocks 1051 is the working surface 1052 of the guide rail block 105. The width of the working surface 1052 is adapted to the width requirement of the tipping paper of the current production specification. The arc-shaped integrated working surface 1052 eliminates the potential hazard of tipping paper scratch defects formed due to the deviation between the inner and outer working surfaces 1052 of the original guide rail. An assembly groove 1054 is opened at the bottom of the guide rail block 105. The assembly groove 1054 is in a "U" - shaped structure. The guide rail block 105 is placed on the surface of the sliding sleeve 104 through the assembly groove 1054. The bottom of the assembly groove 1054 is open, which is convenient to directly take out or install from above during disassembly and assembly, simplifying the replacement steps of the guide rail block 105. Outer limiting blocks 106 and inner limiting blocks 107 are symmetrically arranged at both ends of the guide rail block 105. The shapes of the outer limiting blocks 106 and the inner limiting blocks 107 are both adapted to the shape of the guide rail block 105. A first through - hole 1061 is opened on the outer limiting block 106, and a second through - hole 1071 is opened on the inner limiting block 107. The outer limiting blocks 106 and the inner limiting blocks 107 are respectively assembled to the surface of the sliding sleeve 104 through the first through - hole 1061 and the second through - hole 1071. The positions of the outer limiting blocks 106 and the inner limiting blocks 107 are relatively fixed with respect to the sliding sleeve 104, so that the middle guide rail block 105 always maintains a centered position. The flexible component 108 includes a fixing plate 1081 and a speed reducer 1082. The fixing plate 1081 is fixedly connected to the outer machine frame 101 by bolts. The speed reducer 1082 is arranged on one side of the fixing plate 1081. The speed reducer 1082 provides power for the adjustment of the position of the guide rail block 105, and is electrically operated, reducing the labor intensity of maintenance personnel.

[0030] In this embodiment, guide blocks 105 with at least two common widths of tipping paper are prepared. The shape and structure of the guide blocks 105 are the same, and only the width of the working surface 1052 is equal to the width of the common production tipping paper specification. According to the production schedule requirements, the guide blocks 105 of the corresponding size can be quickly replaced.

[0031] The embodiment of the present invention is also implemented through the following technical solutions.

[0032] In the embodiment of the present invention, a driving gear 1083 and a driven gear 1084 are arranged on one side of the fixing plate 1081 away from the speed reducer 1082. The output shaft of the speed reducer 1082 passes through the fixing plate 1081 and is fixedly connected to the center of the driving gear 1083. The driven gear 1084 meshes with the driving gear 1083. One end of the fixed section 1021 away from the telescopic section 1023 passes through the machine frame 101 and is fixedly connected to the center of the driven gear 1084. The rotational speed of the speed reducer 1082 is selected to be 5 - 15 rpm. The fixing plate 1081 is made of stainless steel. The installation and fixation of the fixing plate 1081 and the speed reducer 1082 do not affect the installation and disassembly of other components inside the machine, and do not interfere with the paper threading operation of the tipping paper. The driving gear 1083 and the passive gear are respectively connected to the output end of the speed reducer 1082 and the end of the lead screw shaft 102, which is compact and firm, and the power transmission is stable. The speed reducer 1082 is controlled by buttons. There are two buttons, which respectively control the forward and reverse rotation of the speed reducer 1082 to move the guide block 105 in and out. The buttons adopt electric normally closed triggering.

[0033] In the embodiment of the present invention, the outer surface of the fixed section 1021 is in sliding contact with the inner wall of the telescopic blind groove 1025. Four transmission columns 1022 are symmetrically arranged at the end of the fixed section 1021. The central axis of the transmission column 1022 is perpendicular to the central axis of the fixed section 1021. Four limiting grooves 1026 are symmetrically formed on the inner wall of the telescopic blind groove 1025. The transmission column 1022 is slidably arranged inside the limiting groove 1026. The transmission column 1022 transmits the rotational force of the fixed section 1021 to the telescopic section 1023. Through the cooperation of the limiting groove 1026 and the transmission column 1022, the telescopic section 1023 ensures that the lead screw shaft 102 does not affect the position of the driven gear 1084 during the process of adjusting the movement of the guide block 105, and prevents the two groups of gears from being misaligned and disengaged.

[0034] In an embodiment of the present invention, a spring member 1031 and a washer 1032 are sleeved on a support shaft 103. One side of the washer 1032 abuts against the side wall of the inner limit block 107, and one end of the spring member 1031 abuts against the side wall of the washer 1032. The spring member 1031 provides a pushing force for the sliding sleeve 104 to move outwards, enabling it to move out smoothly. The inner diameter of the sliding sleeve 104 is adapted to the outer diameter of the support shaft 103. One end of the support shaft 103 close to the lead screw shaft 102 is provided with a guide groove 1033 along the central axis extension direction. A guide key 1041 is arranged on the inner surface of the sliding sleeve 104, and the guide key 1041 is slidably arranged inside the guide groove 1033. The sliding sleeve 104 is matched with the support shaft 103 through the guide key 1041, playing a role in guiding and axial positioning.

[0035] In an embodiment of the present invention, one end of the sliding sleeve 104 abuts against the side wall of the washer 1032, and a retaining ring 1042 is arranged at the other end of the sliding sleeve 104. The diameter of the retaining ring 1042 is equal to the diameter of the sliding sleeve 104. One side of the retaining ring 1042 abuts against the end of the telescopic section 1023. The retaining ring 1042 is used to transmit the displacement of the telescopic section 1023 to the sliding sleeve 104. When it is necessary to adjust the position of the guide rail block 105 inwards, the fixed section 1021 rotates driven by the gear engagement, the telescopic section 1023 rotates synchronously, the threaded column 1024 screws into the threaded hole 1034, and the telescopic section 1023 abuts against the retaining ring 1042 to push the sliding sleeve 104 inwards. When adjusting in the reverse direction, the threaded column 1024 screws outwards, and the spring member 1031 pushes the sliding sleeve 104 outwards through the washer 1032.

[0036] In an embodiment of the present invention, glue accumulation grooves 1053 are provided on both sides of the working surface 1052 near the side positions of the limit bumps 1051. The glue accumulation grooves 1053 are 0.3 mm deep and 2 mm wide. When glue overflows at both ends of the tipping paper, it prevents glue scale from depositing on the working surface 1052 and causing the tipping paper to run off. An avoidance inclined surface 1055 is provided on one side of the assembly groove 1054. The avoidance inclined surface 1055 does not affect the overall strength of the guide rail block 105, which is beneficial for the guide rail block 105 not to interfere with surrounding parts during disassembly and assembly, ensuring more reliable quick disassembly and assembly.

[0037] In an embodiment of the present invention, a first connecting bolt 1062 is arranged on one side of the outer limit block 106. After passing through the outer limit block 106, the first connecting bolt 1062 is threadedly connected to the side wall of the guide rail block 105. A first fastening bolt 1063 is arranged at the bottom of the outer limit block 106. The first fastening bolt 1063 passes through to the inside of the first through hole 1061 and abuts against the outer surface of the sliding sleeve 104. The first fastening bolt 1063 fixes the position of the outer limit block 106 and the sliding sleeve 104. The first connecting bolt 1062 is used to connect the guide rail block 105 and the outer limit block 106.

[0038] In an embodiment of the present invention, a positioning groove 1072 is formed at the top of the inner limiting block 107. The positioning groove 1072 has a "U" - shaped structure. A second connecting bolt 1073 is arranged on one side of the inner limiting block 107. The second connecting bolt 1073 passes through the positioning groove 1072 and is threadedly connected to the side wall of the guide rail block 105. The second connecting bolt 1073 is used for connecting the guide rail block 105 and the inner limiting block 107. The positioning groove 1072 enables the second connecting bolt 1073 to be slightly loosened without removing the second connecting bolt 1073 when the guide rail block 105 needs to be removed and replaced, and the guide rail block 105 can be pulled out upward. A second fastening bolt 1074 is arranged at the bottom of the inner limiting block 107. The second fastening bolt 1074 penetrates into the interior of the second through - hole 1071 and abuts against the outer surface of the sliding sleeve 104. The second fastening bolt 1074 fixes the position of the inner limiting block 107 and the sliding sleeve 104. After the positions of the outer limiting block 106 and the inner limiting block 107 are fixed, the central position of the guide rail block 105 is ensured to remain unchanged, reducing the number of centering debugging times.

[0039] Specifically, the working principle of a water - pine paper guide rail structure capable of quick replacement and flexible adjustment: When it is necessary to replace the guide rail block 105 of different specifications, first take out the first connecting bolt 1062, slightly loosen the second connecting bolt 1073, pull out the guide rail block 105 to be replaced upward, then align the assembly groove 1054 below the new guide rail block 105 with the sliding sleeve 104, insert it downward between the outer limiting block 106 and the inner limiting block 107, and then tighten the first connecting bolt 1062 and the second connecting bolt 1073 respectively, thus completing the quick replacement of the guide rail block 105 with different width specifications. Other structures remain unchanged. After the newly installed guide rail block 105 is fixed, it is on the same center line as the original guide rail block 105, saving complex and repetitive adjustment steps; During the production process, when the water - pine paper tape deviates, the forward and reverse rotations of the reduction gear 1082 are controlled by a button arranged outside the machine. The reduction gear 1082 drives the lead screw shaft 102 to rotate through the driving gear 1083 meshing with the driven gear 1084. The lead screw shaft 102 drives the cooperation depth between the threaded rod at the end of the telescopic section 1023 and the internal thread on the support shaft 103 to change through the fixed end. When it is necessary to adjust the center line inward, the cooperation depth increases, and the telescopic section 1023 pushes the sliding sleeve 104 inward through the retaining ring 1042. When it is necessary to adjust outward, the cooperation depth decreases, and the telescopic section 1023 retracts toward the fixed - end side. At this time, under the elastic action, the spring member 1031 pushes the sliding sleeve 104 outward through the washer 1032, realizing the flexible adjustment of the center line of the water - pine paper, changing the problem of large manual adjustment workload in the traditional method. The adjustment is convenient and safe, and the efficiency of disassembly, replacement and flexible adjustment of the water - pine paper guide rail block 105 is improved.

[0040] It should be noted that the specific model and specifications of the speed reducer 1082 need to be selected according to the actual specifications of the device, etc. The specific selection calculation method adopts the existing technology in the field, so it will not be elaborated in detail here.

[0041] It should be noted that the power supply and its principle of the speed reducer 1082 are clear to those skilled in the art, and will not be elaborated in detail here.

[0042] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
