Description

Technical Field

[0001] This application relates to the field of tobacco machinery technology, specifically to a device for removing the rubber roller of a ZJ17 cigarette machine. Background Technology

[0002] In the production process of the ZJ17 cigarette machine, the glue-applying roller is installed on the glue roller shaft in a tightly fitted manner and is driven to rotate by the glue roller shaft. It is responsible for evenly applying the glue to the tipping paper. This component is in a working environment full of glue, sludge, tobacco dust and other impurities for a long time. This installation method and harsh environment make the contact surface between the glue-applying roller and the glue roller shaft very prone to adhesion.

[0003] However, when it is necessary to replace or maintain the top roller, the shallow grooves at both ends, only about 1 mm deep, make it difficult for conventional disassembly tools (such as pullers) to effectively hook and apply force. The lack of a reliable point of force is the main obstacle to manually or using existing tools to pull the stuck top roller axially away, often resulting in the inability to complete post-shift maintenance in a timely manner, which seriously affects production efficiency.

[0004] Therefore, this application proposes a disassembly device for the top glue roller of a ZJ17 cigarette machine, which can overcome the difficulty of applying force caused by the shallow grooves at both ends of the top glue roller, and provide a stable and reliable force structure, thereby realizing convenient and effective disassembly of the top glue roller along the axial direction of the glue roller. Utility Model Content

[0005] The main purpose of this application is to provide a disassembly device for the upper rubber roller of the ZJ17 cigarette machine, which aims to solve the technical problem that the disassembly tool cannot form an effective force point due to the shallow grooves at both ends of the upper rubber roller of the ZJ17 cigarette machine, thus making it difficult to pull out the sticky rubber roller along the axial direction.

[0006] To achieve the above objectives, this application provides the following technical solution:

[0007] A ZJ17 cigarette machine upper glue roller disassembly device, used to disassemble the upper glue roller sleeved on the glue roller shaft, comprising:

[0008] The clamping assembly includes a first clamping block and a second clamping block arranged opposite to each other; after the two are assembled, a cylindrical cavity is formed inside to accommodate the upper glue roller, and the two ends along the length direction respectively form a circular clamping hole that matches the annular shallow groove on the side wall of the upper glue roller, and a circular through hole for the glue roller shaft to pass through, and the clamping hole and the through hole are both connected to the cavity.

[0009] The support assembly includes a cantilever beam disposed at the end of the clamping assembly away from the clamping hole;

[0010] The drive assembly includes a lead screw coaxial with the roller shaft, one end of which is threaded through the cantilever beam and abuts against the end of the roller shaft.

[0011] As a further improvement of this application, the first clamping block and the second clamping block are provided with semi-cylindrical grooves on their sides that are close to each other, and the two grooves are joined together to form the cavity; the first clamping block and the second clamping block are respectively provided with semi-circular first notches and second cuts at their ends along the length direction, the two first notches are joined together to form the clamping hole, and the two second notches are flat to form the through hole.

[0012] As a further improvement of this application, the clamping assembly further includes bolts, and the outer side walls of the first clamping block and the second clamping block that are close to each other are provided with at least two sets of connecting ears, which are connected by bolts so that the first clamping block and the second clamping block can be spliced ​​together and fixedly connected.

[0013] As a further improvement of this application, the support assembly further includes a first support plate connected to the first clamping block and a second support plate connected to the second clamping block, wherein the first support plate and the second support plate are respectively provided with limiting holes adapted to both ends of the cantilever beam in the length direction.

[0014] As a further improvement of this application, the drive assembly further includes a rotating handle fixedly connected to the end of the lead screw away from the clamping assembly.

[0015] The technical solution provided in this application may include the following beneficial effects:

[0016] During use, this application utilizes a split design for the clamping assembly (the first and second clamping blocks combine to form a cylindrical cavity), allowing the device to be quickly fitted onto the outside of the upper rubber roller. The circular clamping holes at both ends precisely engage with the shallow annular grooves on the side wall of the upper rubber roller to achieve circumferential locking. Simultaneously, the cantilever beam of the support assembly provides a stable fulcrum for the drive assembly, enabling the lead screw, coaxial with the rubber roller shaft, to directly abut against the shaft end and apply force via threaded advancement. This structure completely eliminates the traditional hammer-based disassembly method. During the uniform advancement of the lead screw, the axial tension is evenly transmitted to the upper rubber roller via the rubber roller shaft, avoiding the risks of rubber roller deformation, bearing damage, or flying fragments caused by hammering, significantly improving disassembly safety and parts reuse rate.

[0023] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the described embodiments are merely some, not all, of the embodiments of this application. Unless otherwise specified, the embodiments and features described in this application can be combined with each other. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0024] Figure 1 An embodiment of the adhesive roller removal device for a ZJ17 cigarette machine is shown in this application. See [link to relevant documentation]. Figure 1 In this embodiment, the ZJ17 cigarette machine upper glue roller disassembly device is used to disassemble the upper glue roller 100 sleeved on the glue roller shaft 200, and includes: clamping component 1, support component 2 and drive component 3.

[0025] Among them, see Figure 1The clamping assembly 1 includes a first clamping block 11 and a second clamping block 12 arranged opposite to each other. When the two are assembled, a cylindrical cavity 13 is formed inside to accommodate the upper rubber roller 100. The two clamping blocks 11 and 12 respectively form circular clamping holes 14 that match the annular shallow grooves 1001 on the side wall of the upper rubber roller 100, and circular through holes 15 for the rubber roller shaft 200 to pass through. Both the clamping holes 14 and the through holes 15 are connected to the cavity 13. The support assembly 2 includes a cantilever beam 21 located at the end of the clamping assembly 1 away from the clamping holes 14. The drive assembly 3 includes a lead screw 31 coaxial with the rubber roller shaft 200. One end of the lead screw 31 is threaded through the cantilever beam 21 and abuts against the end of the rubber roller shaft 200. By employing a split design for the clamping assembly 1 (the first clamping block 11 and the second clamping block 12 combine to form a cylindrical cavity 13), the device can be quickly fitted onto the outside of the upper rubber roller 100. The circular clamping holes 14 formed at both ends precisely engage with the annular shallow groove 1001 on the side wall of the upper rubber roller 100 to achieve circumferential locking. Simultaneously, the cantilever beam 21 of the supporting assembly 2 provides a stable fulcrum for the driving assembly 3, allowing the lead screw 31, coaxial with the rubber roller shaft 200, to directly abut against the shaft end and apply force via threaded advancement. This structure completely eliminates the traditional hammer-based disassembly method. During the uniform advancement of the lead screw 31, the axial tension is evenly transmitted to the upper rubber roller 100 via the rubber roller shaft 200, avoiding the risks of rubber roller deformation, bearing damage, or flying fragments caused by hammering, significantly improving disassembly safety and parts reuse rate.

[0026] Further, see Figure 1 The first clamping block 11 and the second clamping block 12 each have a semi-cylindrical groove 16 on their adjacent sides, and the two grooves 16 are joined together to form a cavity 13. The first clamping block 11 and the second clamping block 12 have a semi-circular first notch 17 and a second cut 18 at their respective ends along their length. The two first notches 17 are joined together to form a clamping hole 14, and the two second notches are flat to form a through hole 15. By setting the semi-cylindrical groove 16 and the semi-circular notches at both ends on the first clamping block 11 and the second clamping block 12, the cavity 13, the clamping hole 14 and the through hole 15 after being joined together form a coaxial positioning reference. This ensures that the clamping assembly 1 accurately wraps around the rubber roller 100 while automatically aligning the annular shallow groove 1001 with the rubber roller shaft 200, completely eliminating the risk of misalignment during separate assembly and ensuring the axial transmission accuracy of the disassembly force.

[0027] Further, see Figure 2 The clamping assembly 1 also includes at least two sets of bolts; corresponding connecting ears 19 are provided on the facing side walls of the first clamping block 11 and the second clamping block 12, and each bolt passes through the connecting ears 19 of the same set and is tightened to fix the first clamping block 11 and the second clamping block 12 together. By providing a bolt locking structure with connecting ears 19 on the facing side walls of the first clamping block 11 and the second clamping block 12, the split clamping blocks can be quickly assembled and uniformly constrained, completely eliminating the risk of clamping slippage or rubber roller damage caused by local stress concentration in traditional clamps, and ensuring high stability during the disassembly process.

[0028] Optionally, in this embodiment, two sets of bolts are provided, located on both sides of the mating surface of the first clamping block 11 and the second clamping block 12, respectively.

[0029] Further, see Figure 2 The support assembly 2 also includes a first support plate 22 connected to the first clamping block 11 and a second support plate 23 connected to the second clamping block 12. The first support plate 22 and the second support plate 23 are respectively provided with limiting holes that are adapted to both ends of the cantilever beam 21 along its length. By providing support plates with limiting holes on the first clamping block 11 and the second clamping block 12, the two ends of the cantilever beam 21 are given bidirectional rigid constraints, which completely eliminates the risk of torsional deformation of the cantilever beam 21 when the lead screw 31 is pushed forward, and ensures the linear motion accuracy and device stability during the disassembly process of the rubber roller shaft 200.

[0030] Further, see Figure 2 The drive assembly 3 also includes a rotary handle 32 fixedly connected to the end of the lead screw 31 away from the clamping assembly 1. By fixing the rotary handle 32 to the end of the lead screw 31, the threaded advance of the lead screw 31 is transformed into a force-saving lever mechanism, enabling the operator to achieve uniform displacement of the rubber roller shaft 200 with a torque of ≤5 N·m. While eliminating the risk of hammering, it ensures that the axial traction force is constant and controllable during the disassembly process, achieving human-machine adaptation for "zero-impact" disassembly of precision parts.

[0031] For example, the usage and working principle of the adhesive roller removal device for the ZJ17 cigarette machine are explained:

[0032] During operation, the first and second clamping blocks 11 and 12 are first wrapped around the outside of the rubber roller 100 to be disassembled, so that the semi-circular notches at both ends of the clamping blocks are precisely engaged with the annular shallow grooves 1001 on the side wall of the rubber roller 100 (forming clamping holes 14) and sleeved onto the rubber roller shaft 200 (forming through holes 15); the bolts of the connecting ears 19 on the side wall of the clamping blocks are tightened, so that the two clamping blocks are assembled into a rigid whole, and the rubber roller 100 is fixed with zero displacement by circumferential locking through the annular shallow grooves 1001. Then, the two ends of the cantilever beam 21 are embedded into the limiting holes of the first and second support plates 23 to form an anti-torsional support structure. At this time, the handle 32 at the end of the screw 31 is rotated to drive the screw 31, which is coaxial with the rubber roller shaft 200, to advance at a uniform speed, and its end continuously presses against the end face of the rubber roller shaft 200 to generate axial traction force. Under the mechanical gain effect of the screw thread 31, the manual torque is converted into a constant axial tension, which makes the rubber roller shaft 200 smoothly exit from the inner hole of the interference fit upper rubber roller 100 without any impact load throughout the process.

[0033] In this embodiment, the circumferential locking of the rubber roller's annular shallow groove 1001 by the split clamping assembly 1, combined with the axial constant force traction of the lead screw 31, completely eliminates the problems of rubber roller deformation, bearing breakage, and fragmentation caused by traditional hammering disassembly. The cylindrical cavity 13 formed by the assembly of the split clamping blocks and the clamping hole 14 precisely constrain the radial displacement of the rubber roller. Combined with the uniform advancement of the coaxial lead screw 31 supported by the cantilever beam 21, the torque of the handle 32 is converted into a constant axial tension, allowing the rubber roller shaft 200 to smoothly exit from the interference fit hole. The limiting hole structure of the support plate eliminates the off-center load of the lead screw 31, ensuring coaxiality error. Ultimately, zero-damage disassembly of the precision rubber roller is achieved, maintenance efficiency is improved, the scrap rate of spare parts is reduced, and the safety hazards of hammering operations are eliminated, providing a revolutionary solution for tobacco equipment maintenance.

[0034] The above description is merely a preferred embodiment of this application and is not intended to limit this application. 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.
