Description

Technical Field

[0001] This utility model relates to the field of tobacco equipment technology, and in particular to a multi-specification paper guide block quick switching and positioning component, a paper guide mechanism and a winding and splicing unit. Background Technology

[0002] The positioning of the paper guide block in the winding and splicing unit relies heavily on repeated manual adjustments. Due to the lack of standardized positioning benchmarks, existing technology cannot quickly adapt to different specifications of tipping paper, such as 60mm, 66mm, and 72mm. Switching to special grades often requires manual adjustments, increasing the workload for operators and hindering the continuity of multi-grade production. Furthermore, operators must disassemble bolts, manually measure, and retighten them to achieve station switching, resulting in insufficient positioning accuracy (often exceeding ±0.3mm deviation), leading to quality defects such as uneven tipping tips and curled edges in the tipping paper. Frequent adjustments make each type change take 3-5 minutes, significantly reducing the effective operating rate of the equipment. The repeated disassembly and assembly processes also accelerate component wear, increasing annual maintenance costs.

[0003] Therefore, there is an urgent need for a multi-specification paper guide block quick-switching positioning component, paper guide mechanism, and winding and splicing unit to solve the above problems. Utility Model Content

[0004] One objective of this invention is to provide a multi-specification paper guide block quick-switching and positioning component to solve the problems of poor adjustment accuracy, low work efficiency, and high maintenance costs when manually adjusting the paper guide block in the prior art.

The first end of the scale is connected to the standard member, and the second end of the scale is inserted into the slot. The fasteners are used to fix the second end to the sliding member.

[0008] The paper guide structure includes two paper guide blocks fixed at intervals on the bracket, and the positioning structure is sandwiched between the two paper guide blocks.

[0009] Optionally, the sliding component is further provided with a fixing hole, the fixing hole communicating with the slot, and the fastener including a fastening screw, the fastening screw being threaded into the fixing hole and pressing against the scale.

[0010] Optionally, the inner wall of the slot is provided with a limiting groove, the limiting groove is connected to the fixing hole, the fastener further includes a spring plate, the spring plate is located in the limiting groove, and the fastening screw is threaded into the fixing hole and abuts against the scale through the spring plate.

[0013] Optionally, the scale is integrally formed with the standard.

[0014] Optionally, the paper guide block includes a paper guide block body and a connector. The paper guide block body has an installation slit for dividing the paper guide block body into a first part and a second part with a gap. The connector is used to clamp the first part and the second part so that the paper guide block body can be fixed to the bracket.

[0015] Another objective of this invention is to provide a paper guiding mechanism to solve the problems of poor adjustment accuracy, low work efficiency, and high maintenance costs when manually adjusting the paper guide block in the prior art.

[0016] Based on the above concept, the technical solution adopted by this utility model is as follows:

[0017] A paper guiding mechanism is provided, including a connecting component and the aforementioned multi-specification paper guide block quick switching and positioning component. The connecting component includes a bracket, and the multi-specification paper guide block quick switching and positioning component is detachably mounted on the bracket.

The paper guide structure includes two paper guide blocks fixed at intervals on the bracket. The positioning structure is sandwiched between the two paper guide blocks. The distance between the two paper guide blocks is the axial length of the positioning structure on the sliding member. Adjusting the distance between the two paper guide blocks adjusts the depth of the scale inserted into the slot. Because both the sliding and standard components are ring-shaped, meaning the positioning structure can rotate around the circumference of the support, operators can adjust the position of the paper guide structure from either side of the support, rather than being limited to the fixed side. This adjustment eliminates the need for multi-angle comparisons of the fixed position of the paper guide block, effectively improving adjustment accuracy and operational efficiency.

[0038] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0039] Example 1

[0040] like Figure 1 and Figure 2 As shown, this embodiment provides a multi-specification paper guide block quick-switching positioning assembly, including a positioning structure 1 and a paper guide structure 2, both of which are mounted on a bracket 3 of a winding and splicing unit. The positioning structure 1 includes a sliding member 11, a standard member 12, a scale 13, and a fastener 14. Both the sliding member 11 and the standard member 12 are annular structures, fitted onto the bracket 3. The sliding member 11 has a slot 111 at one end near the standard member 12 along its own axial direction. The first end of the scale 13 is connected to the standard member 12, and the second end of the scale 13 is inserted into the slot 111. The fastener 14 is used to fix the second end to the sliding member 11, thereby making the sliding member 11, the standard member 12, and the scale 13 a whole.

[0041] The paper guide structure 2 includes two paper guide blocks fixed at intervals on the bracket 3, with the positioning structure 1 sandwiched between the two paper guide blocks. The two paper guide blocks include a first paper guide block and a second paper guide block. The first paper guide block is located on the side of the sliding member 11 opposite to the scale 13, and the second paper guide block is located on the side of the standard member 12 opposite to the scale 13. The first paper guide block is a movable paper guide block, and the second paper guide block is a fixed paper guide block. When the second paper guide block is fixed on the bracket 3, it is assembled into a single positioning structure 1. The position of the first paper guide block on the bracket 3 can be limited by abutting against the second paper guide block. The distance between the first and second paper guide blocks is the axial length of the positioning structure 1 on the sliding member 11. Adjusting the distance between the first and second paper guide blocks adjusts the depth of the scale 13 inserted into the slot 111. Multiple scale values, such as 60mm, 66mm, and 72mm, are set at intervals along the axial direction of the sliding member 11 on the scale ruler 13. The sliding member 11, the standard member 12, and the scale ruler 13 work together so that the value of the scale corresponding to the edge of the sliding member 11 is the distance between the first paper guide block and the second paper guide block. The operator can directly move the sliding member 11 to the corresponding scale value to adjust the position of the paper guide structure 2, which is convenient and quick.

[0042] Furthermore, both the sliding component 11 and the standard component 12 provided in this embodiment are annular structures, meaning that the positioning structure 1 can rotate around the circumference of the support 3. This allows the operator to adjust the position of the paper guide structure 2 from any side of the support 3, rather than being limited to the side where the paper guide structure 2 is fixed. The distance between the first and second paper guide blocks can be fixed first using fasteners 14, and then the first paper guide block can be moved until it presses against both sides of the positioning structure 1, after which the first paper guide block can be fixed. This adjustment does not require multi-angle comparison of the fixed position of the paper guide block, effectively improving adjustment accuracy and work efficiency, while avoiding wear on components from multiple adjustments and reducing maintenance costs. In specific implementation, the cooperation of the positioning structure 1 and the paper guide structure 2 can achieve the goal of millimeter-level precise positioning within 15 seconds of a single operation, while reducing the amount of adjustment and positioning tooling by approximately 90%, eliminating long-side deviation and warping faults caused by displacement, and reducing operational intensity.

[0043] In this embodiment, the scale 13 and the standard 12 are integrally formed. This eliminates the need for a fixing structure between the scale 13 and the standard 12, and also avoids errors caused by their connection.

[0044] In this embodiment, the scale 13 is an arc-shaped structure extending circumferentially along the sliding member 11, and the slot 111 is an arc-shaped groove extending circumferentially along the sliding member 11. Since both the sliding member 11 and the standard member 12 are annular structures, the positioning structure 1 can be coaxially mounted on the bracket 3, and the positioning structure 1 can also rotate around the bracket 3. When adjusting the fixed position of the sliding member 11 and the scale 13, it is only necessary to rotate the scale 13 into the operator's field of vision, without needing to set up an annular scale 13. The scale 13 is designed as an arc-shaped piece, which not only reduces the weight of the positioning structure 1 but also facilitates processing and prevents deformation.

[0045] Optionally, such as Figure 2 As shown, the sliding component 11 is also provided with a fixing hole 112, which communicates with the slot 111. The fastener 14 includes a fastening screw, which is threaded into the fixing hole 112 and presses against the scale 13. The inner wall of the fixing hole 112 is provided with an internal thread structure, and the outer periphery of the fastening screw is provided with an external thread connection. Rotating the fastening screw can move the fastening screw closer to or away from the scale 13, thereby fixing or releasing the scale 13 in the slot 111.

[0046] Optionally, a limiting groove 113 is provided on the inner wall of the slot 111, which communicates with the fixing hole 112. The fastener 14 also includes a spring plate located in the limiting groove 113. The fastening screw is threaded into the fixing hole 112 and abuts against the scale 13 through the spring plate. The elastic force applied by the spring plate to the scale 13 causes the scale 13 to be pressed against the inner wall of the slot 111 on the side away from the fastener 14. Compared with the fastening screw directly pressing against the scale 13, the spring plate pressing against the scale 13 can reduce the wear on the scale 13 and the sliding member 11.

[0047] Optionally, a fixing protrusion 114 is provided on the outer wall surface of the sliding member 11. The fixing protrusion 114 abuts against the head surface of the fastening screw, and the shank of the fastening screw is threaded into the fixing hole 112. In this embodiment, the sliding member 11 is an annular structure, so the outer peripheral surface of the sliding member 11 is an arc-shaped surface. When the shank of the fastening screw passes through the fixing hole 112, the head of the fastening screw abuts against the outer peripheral surface of the sliding member 11. The head of the fastening screw is a cylindrical structure, and the surface of the head abutting against the sliding member 11 is a plane. To ensure stable abutment between the fastening screw and the sliding member 11, a fixing protrusion 114 is provided at the abutment point of the sliding member 11, so that the abutment surface of the fixing protrusion 114 abutting against the fastening screw is also a plane. In this embodiment, the fixing protrusion 114 is a long strip structure extending along the axial direction of the sliding member 11. One side of the long strip structure connecting to the outer peripheral surface of the sliding member 11 is an arc-shaped surface, and the side abutting against the fastening screw is a plane.

[0048] Optionally, the paper guide block includes a paper guide block body 21 and a connector 22. The paper guide block body 21 has an installation slit, which divides the paper guide block body 21 into a first part and a second part with a gap. The connector 22 is used to clamp the first part and the second part so that the paper guide block body 21 can be fixed to the bracket 3. The paper guide block body 21 passes through the bracket 3, and the paper guide block body 21 has a through hole. One end of the installation slit is connected to the through hole radially, and the other end passes through the paper guide block body 21. The installation slit is provided so that the first part and the second part can be brought closer together under the action of the connector 22 to reduce the size of the through hole, thereby allowing the paper guide block body 21 to be clamped on the bracket 3. The connector 22 can be a screw and nut structure. The paper guide block body 21 has a connecting hole that passes through the first part and the second part. The screw passes through the connecting hole and is connected to the nut to fix the first part and the second part to the bracket 3.

[0049] Example 2

[0050] like Figure 3As shown, this embodiment provides a paper guiding mechanism, including a connecting component and a multi-specification paper guide block quick-switching and positioning component. The connecting component includes a bracket 3, and the multi-specification paper guide block quick-switching and positioning component is detachably mounted on the bracket 3. In this embodiment, the bracket 3 is a cylindrical structure, and both the paper guiding structure 2 and the positioning structure 1 are sleeved on the bracket 3.

[0051] Optionally, the connecting assembly further includes a connecting plate 4, one end of which is connected to the bracket 3, and the other end of which is connected to the main body of the winding and splicing unit. In this embodiment, the bracket 3 is a cylindrical structure, and one end of the cylindrical structure is provided with a through hole so that screws and the like can pass through the through hole and connect to the connecting plate 4. The paper guiding structure 2 and the positioning structure 1 can be sleeved onto the bracket 3 from the end of the bracket 3 that is not connected to the connecting plate 4.

[0052] Example 3

[0053] This embodiment provides a winding and splicing unit, including a main body of the winding and splicing unit and the aforementioned paper guiding mechanism. The connecting plate 4 of the paper guiding mechanism is connected to the main body of the winding and splicing unit. In this embodiment, the connecting plate 4 has an L-shaped structure. One end of the connecting plate 4 is connected to the bracket 3, and the other end of the connecting plate 4 is provided with a strip hole. A fastener can be used to pass through the strip hole and connect to the main body of the winding and splicing unit. The position of the fastener passing through the strip hole is different, so that the position of the connecting plate 4 fixed on the main body of the winding and splicing unit is adjustable.
