Description

Technical Field

[0001] This application belongs to the technical field of cigarette production machinery and equipment, and in particular relates to the tooling for adjusting the guide rail of the accelerating drum of a cigarette machine. Background Technology

[0002] During the operation of cigarette production equipment, the accelerating drum 7, as one of the important components of the filter supply system, mainly functions to receive the double-length filter segment transmitted by the parallel drum and transfer it to the converging drum, forming a "cigarette group" with two short cigarette segments separated by a certain distance. The accelerating drum is the only drum without negative pressure suction. Therefore, when the accelerating drum transfers the double-length filter segment to the converging drum, it mainly relies on the support of the middle guide rail of the accelerating drum guide rail assembly and the centering effect of the guide rails on both sides to ensure that the double-length filter segment remains centered and does not tilt during the transmission process.

[0003] The acceleration drum guide rail assembly currently used in cigarette making machines mainly consists of two side guide rails and a middle support guide rail, totaling four guide rails. The four guide rails are fixed to the equipment wall panel by a fixed connecting rod. The middle support guide rail is fixed and its main function is to support the double-length filter section, preventing the filter section from tilting or falling during transmission. The two side guide rails are symmetrically fixed to the connecting rods along the cutting center by set screws. The length of the double-length filter section is adjusted according to the different cigarette specifications and brands to ensure that the center of the double-length filter section remains aligned with the cutting center line during transmission. Therefore, when producing different specifications and grades of equipment and maintaining equipment, it is necessary to adjust the guide rail of the acceleration drum. However, the working space in this area is very limited. It is necessary to remove the entire guide rail, loosen the set screws on the guide rail, and use a vernier caliper to adjust the distance between the two guide rails symmetrically to the required distance before reinstalling the equipment. If the adjustment deviation is large, the double-length filter section will become skewed or broken during the transmission process, resulting in low production efficiency, excessive consumption, and the need for repeated manual adjustments, which takes a long time and is labor-intensive. Utility Model Content

[0004] The purpose of this application is to provide a tooling for adjusting the guide rail of the acceleration drum of a cigarette machine, which can save debugging time and improve debugging efficiency.

[0005] To achieve the above objectives, this utility model provides a tooling for adjusting the guide rail of the acceleration drum of a cigarette machine, comprising: A fixed support, which provides an installation base; The guide component is fixedly mounted on the fixed support; At least two reference blocks are provided, the positions of which are adjustable on the guide, and there is a gap between adjacent reference blocks.

[0006] In an optional embodiment, the guide includes an installation section, a guide section, and a screwing section. The guide section is fixedly connected between the installation section and the screwing section. The installation section is threadedly fixed on the fixed support. The reference block is adjustablely installed on the guide section. The screwing section has a wrench-fitting structure.

[0007] In an optional embodiment, the mounting section is configured to have external threads, and the fixed support is provided with a mounting threaded hole that mates with the external threads on the mounting section.

[0008] In an optional embodiment, the wrench engagement structure is provided on one end of the screwing section away from the guide section, and the wrench engagement structure is configured as a multi-faceted hole.

[0009] In an optional embodiment, the reference block is provided with a mating through hole, and the reference block is sleeved on the guide section through the mating through hole; The reference block is also provided with a locking threaded hole that communicates with the mating through hole. The locking threaded hole is perpendicular to the mating through hole. A locking element is threaded into the locking threaded hole. The locking element presses against the guide element so that the reference block is locked relative to the guide element.

[0010] In an optional embodiment, the guide is configured as a rod-shaped structure.

[0011] In an optional embodiment, an anti-rotation plane is provided on the guide section, and the locking member abuts against the anti-rotation plane; At least two anti-rotation planes and reference blocks are provided respectively.

[0012] In an optional implementation, guide circles are provided at both ends of the reference block.

[0013] In an optional embodiment, the fixed support is configured as a trapezoidal structure.

[0014] In an optional embodiment, the guide is provided with at least two reference structures for comparing the position of the reference block.

[0015] Traditional adjustment methods are cumbersome and experience-dependent, requiring disassembly and reassembly of the guide rails and repeated measurement and adjustment of the spacing using calipers. The fixture provided in this application, however, uses a combination of guide components and a reference block. Once the reference block is slid to the target position and fixed, it serves as the adjustment benchmark, eliminating the need to disassemble the guide rails and significantly simplifying the operation. The fixture has a compact structure and can be directly installed via a fixed support, adapting to limited working spaces and solving the operational difficulties of traditional methods. The adjustable and fixed reference block forms a stable benchmark, ensuring accurate guide rail positioning and avoiding traditional measurement errors. The new fixture achieves simultaneous positioning of both guide rails in a single adjustment, reducing repetitive operations and significantly lowering the labor intensity of maintenance workers.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0021] In the description of this application, it should be noted that the terms "inner" and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. They are used only for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0022] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0023] Embodiments of this application provide a tooling for adjusting the guide rail of the accelerating drum of a cigarette machine, including a fixed support 4, a guide 1, and at least two reference blocks 2.

[0024] like Figure 1 As shown, the mounting bracket 4 is used to provide an installation base. Exemplarily, the mounting bracket 4 is fixedly mounted on the frame of the cigarette machine or other fixed platform, such as a wall.

[0025] like Figure 1 As shown, guide 1 is fixedly mounted on fixed support 4. Guide 1 is used to guide the movement of reference block 2 to define the movement path of reference block 2.

[0026] like Figure 2 As shown, the reference block 2 is adjustablely positioned on the guide 1, and there is a gap between adjacent reference blocks 2.

[0027] For example, two reference blocks 2 are provided. In another embodiment, three reference blocks 2 are provided; of course, other numbers of reference blocks 2 can also be provided, such as four or five. The technical solution of this application will be described below using the example of providing two reference blocks 2.

[0028] like Figures 1 to 3As shown, when using the adjustment fixture for the acceleration drum 7 guide rail, first fix the guide 1 to the fixed support 4, install the two reference blocks 2 onto the guide 1, and slide the two reference blocks 2 according to the required double-length filter section length of the cigarettes to be produced, so that their outer surfaces correspond to the required positions, and then fix them. The acceleration drum 7 is fixedly equipped with two side guide rails 6, which are slidably mounted on the guide rail connecting rod 5. The guide rail connecting rod 5 is fixedly mounted on the fixed seat. Loosen the set screws 601 on the two side guide rails 6 of the acceleration drum 7, move the two side guide rails 6 until the inner surfaces of the two side guide rails 6 are respectively in contact with the outer surfaces of the reference blocks 2, and tighten the set screws 601 on the two side guide rails 6 of the acceleration drum 7. The adjustment of the acceleration drum 7 guide rail is now complete. By using the adjustment fixture, the adjustment time of the acceleration drum 7 guide rail can be effectively reduced, the adjustment accuracy improved, the labor intensity of maintenance workers reduced, and the equipment working efficiency effectively improved.

[0029] Traditional adjustment methods require disassembling the entire guide rail, loosening the set screw 601, and repeatedly measuring and adjusting the spacing with calipers, which is cumbersome and relies on experience. However, the tooling provided in this application, through the combined design of guide component 1 and reference block 2, allows the reference block 2 to be slid directly onto the guide component 1 to the target position and fixed, serving as the adjustment benchmark for both guide rails 6 without the need to disassemble the guide rails, greatly simplifying the operation steps.

[0030] The tooling is directly installed on the cigarette machine frame or fixed table via the fixed support 4, without taking up extra space. The guide 1 and reference block 2 have a compact structure, which is suitable for the limited working space in the acceleration drum 7 area, and solves the problem of operation difficulties caused by space constraints in traditional methods.

[0031] The position of reference block 2 is adjustable and fixed to form a stable benchmark. The guide rails 6 on both sides are positioned by directly contacting the outer side of reference block 2, which avoids the problem of inaccurate adjustment caused by the measurement error of vernier calipers or the deviation of manual reading in the traditional method, and ensures that the center of the double-length filter section coincides with the cutting center line.

[0032] Traditional methods require manual disassembly and reassembly of the guide rails, measurement of spacing, and adjustment, which is labor-intensive and inefficient. The new fixture can complete the synchronous adjustment of the guide rails 6 on both sides by sliding the reference block 2 to the target position and fixing it at one time, avoiding multiple disassembly and measurement, and greatly reducing the physical exertion of maintenance workers.

[0033] like Figure 4 As shown, in one embodiment, the guide 1 includes an installation section 102, a guide section 105, and a screwing section 104.

[0034] The guide section 105 is fixedly connected between the mounting section 102 and the screwing section 104, and the fixing method is, for example, welding, snap-fit, threaded connection or integral molding. The reference block 2 is adjustablely mounted on the guide section 105, which provides a base for the sliding of the reference block 2.

[0035] The mounting section 102 is threadedly fixed on the fixed support 4, and the mounting section 102 is used to fix the guide 1 on the fixed support 4.

[0036] The screwing section 104 has a wrench-fitting structure, which facilitates the wrench to screw the guide member 1 so that the thread of the mounting section 102 is tightened onto the fixed support 4.

[0037] For example, the wrench mating structure is configured as a multi-prism structure, such as a triangular prism, a square prism, a pentagonal prism, or a hexagonal prism.

[0038] Unlike the above embodiments where the wrench-fitting structure is a multi-prism structure, such as... Figure 2 or Figure 4 As shown, in one embodiment, a wrench-fitting structure is provided on the end of the screwing section 104 away from the guide section 105. The wrench-fitting structure is configured as a multi-faceted hole, such as a hexagonal hole with a specification of M6. The multi-faceted hole structure can also be a triangular hole, a quadrangular hole, or a pentagonal hole, etc.

[0039] The tightening section 104 is equipped with a wrench-fitting structure, which greatly facilitates the installation operation. When tightening the threads of the mounting section 102 onto the fixed support 4, the wrench can easily engage with the fitting structure of the tightening section 104. By rotating the wrench, a large torque can be applied, ensuring a tight connection between the mounting section 102 and the fixed support 4. This avoids the problem of loosening caused by insufficient tightening force or inconvenient operation, thus improving installation efficiency and connection quality.

[0040] like Figure 3 As shown, in one embodiment, the mounting section 102 is provided with an external thread, the external thread being 10mm long and having a specification of M5.

[0041] The fixed support 4 is provided with a mounting threaded hole that mates with the external thread on the mounting section 102. The mounting threaded hole is 6mm deep and has an M6 specification.

[0042] like Figure 5 As shown, in one embodiment, a fitting through hole 201 is provided on the reference block 2, and the reference block 2 is sleeved on the guide section 105 through the fitting through hole 201.

[0043] The reference block 2 is also provided with a locking threaded hole 202 that communicates with the mating through hole 201. The locking threaded hole 202 is perpendicular to the mating through hole 201. A locking element 3 is threaded in the locking threaded hole 202. The locking element 3 presses against the guide element 1 so that the reference block 2 is locked relative to the guide element 1.

[0044] For example, the locking element 3 is configured as an M6×10mm screw.

[0045] like Figure 4 As shown, in one embodiment, the guide 1 is configured as a rod-shaped structure. The rod-shaped structure has a defined axial direction, which can provide stable linear guidance for the reference block 2, ensuring that the reference block 2 slides along a predetermined direction, thereby guaranteeing the positioning accuracy of the mechanical structure.

[0046] like Figure 5 As shown, in one embodiment, the guide segment 105 is provided with an anti-rotation plane 101, and the locking member 3 presses against the anti-rotation plane 101 to further lock the reference block 2.

[0047] At least two anti-rotation planes 101 are provided, corresponding to reference block 2.

[0048] For example, if two reference blocks 2 are set, two anti-rotation planes 101 are set accordingly. If three reference blocks 2 are set, three anti-rotation planes 101 are set accordingly.

[0049] An anti-rotation plane 101 is provided on the guide section 105, and the reference block 2 is locked by clamping the anti-rotation plane 101 with the locking member 3. This design effectively prevents the reference block 2 from rotating when subjected to external forces. During mechanical operation, the reference block 2 needs to maintain a stable position to provide an accurate reference benchmark. If the reference block 2 rotates, it will cause positional deviations in other components that it mates with, affecting the accuracy and performance of the entire mechanical system. The cooperation between the anti-rotation plane 101 and the locking member 3 provides a reliable anti-rotation mechanism for the reference block 2, ensuring its positioning accuracy.

[0050] Compared with a single locking method, the combination of the anti-rotation plane 101 and the locking element 3 can enhance the reliability of the lock. When the locking element 3 presses against the anti-rotation plane 101, it generates a large frictional force, which firmly fixes the reference block 2 on the guide section 105 and is not easily loosened by external forces such as vibration and impact.

[0051] like Figure 5As shown, in one embodiment, guide circles are provided at both ends of the reference block 2. During the assembly, transportation, or operation of the mechanical structure, the reference block 2 may accidentally come into contact or collide with other components. Sharp edges and corners can easily cause scratches, bumps, or damage to other components upon collision, and may even lead to deformation or breakage of the components. The design of the guide circles makes the contact between the reference block 2 and other components gentler, reducing the impact force during collision, thereby effectively protecting the various components of the equipment itself and extending the service life of the equipment.

[0052] like Figure 6 As shown, in one embodiment, the fixed support 4 is configured as a trapezoidal structure to reduce stress concentration.

[0053] like Figure 4 As shown, in one embodiment, the guide 1 is provided with at least two reference structures 103 for comparing the position of the reference block 2.

[0054] For example, the number of reference structures 103 corresponds to the number of reference blocks 2; if two reference blocks 2 are set, two reference structures 103 are set accordingly; if three reference blocks 2 are set, three reference structures 103 are set accordingly.

[0055] For example, the distance between the reference structures 103 is 50.5 mm or 54.5 mm, etc.

[0056] For example, the reference structure 103 is symmetrically arranged.

[0057] For example, reference structure 103 can be a reference line.

[0058] like Figure 1 or Figure 6 As shown, when using the tooling to adjust the guide rail of the acceleration drum 7, first use an Allen wrench to apply force to the wrench engagement structure at one end of the guide component 1 to tighten the mounting section 102 of the guide component 1 onto the fixed support 4. Then, fit the two reference blocks 2 onto the guide component 1. Slide the two reference blocks 2 according to the required double-length filter section length of the cigarettes to be produced so that their outer surfaces correspond to the corresponding reference structures 103. Use the locking piece 3 to fix the reference blocks 2 at the anti-rotation plane 101 of the guide component 1 through the locking threaded hole 202. Loosen the set screws 601 on the guide rails 6 on both sides of the acceleration drum 7, and move the guide rails 6 on both sides until the inner surfaces of the guide rails 6 on both sides are close to the outer surfaces of the reference blocks 2. Tighten the set screws 601 on the guide rails 6 on both sides of the acceleration drum 7. At this point, the guide rail adjustment of the acceleration drum 7 is complete.

[0059] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0060] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
