Description

Technical Field

[0001] This utility model relates to the field of packaging machinery and logistics equipment technology, and in particular to a posture adjustment mechanism for irregularly shaped cigarette boxes. Background Technology

[0002] In the tobacco industry's cigarette box packaging, sorting, and palletizing processes, cigarette boxes often exhibit inconsistent postures on the conveyor line, especially irregularly shaped cigarette boxes, which are more prone to orientation confusion and tilting.

[0003] Currently, common methods for adjusting the posture of cigarette boxes mostly involve fixed guide plates, mechanical push rods, or manual intervention. While these traditional methods can achieve posture adjustment to some extent, they still have the following significant drawbacks:

[0004] 1. Low adjustment accuracy and poor adaptability: The fixed guide mechanism cannot be flexibly adjusted according to the size of the tobacco box, and has poor adaptability to tobacco boxes of different specifications, which can easily lead to adjustment failure or tobacco box jamming.

[0005] 2. Low efficiency: Traditional mechanisms often require the smoke box to stop or slow down before adjustments can be made, which increases process time and affects the overall sorting and palletizing efficiency;

[0006] 3. Complex structure and high maintenance cost: Some mechanical push rod mechanisms have complex structures, are difficult to install and debug, have high daily maintenance costs, and have a relatively high failure rate;

[0007] 4. Inability to achieve dynamic adjustment: Most existing technologies are static or semi-static adjustment methods, which cannot achieve real-time and dynamic attitude correction during continuous conveying of the smoke box, resulting in limited production efficiency. Utility Model Content

[0008] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing a non-standard cigarette box posture adjustment mechanism.

[0009] To achieve the above objectives, the present invention adopts the following technical solution: a non-standard cigarette box posture adjustment mechanism, comprising a side plate, a double-ear ring support fixedly installed on the inner side of the side plate by screws and nuts, an ear ring mounting component hinged on the double-ear ring support, a cylinder fixedly installed on the ear ring mounting component, a Y-shaped pin connecting rod connected to the piston rod end of the cylinder, the other end of the Y-shaped pin connecting rod being connected to the portion of the rotating shaft located on the inner side of the side plate by a movable pin, the rotating shaft being fixedly installed on the inner side of the side plate by a mirror bearing seat, a connecting rod fixedly connected to the portion of the rotating shaft located on the outer side of the side plate, a non-powered pulley rotatably installed on the connecting rod, and screw holes for fixing the entire mechanism to the cigarette conveying line on both the upper and lower edges of the side plate.

[0010] Preferably, the double earring support is fastened to the side plate by bolts, and the earring mounting piece is hinged to the double earring support by a pin.

[0011] Preferably, one end of the Y-shaped pin-connecting rod is connected to the piston rod of the cylinder via a thread or pin, and the end of the Y-shaped pin-connecting rod away from the cylinder is connected to the rotating shaft via a movable pin.

[0012] Preferably, the rotating shaft is mounted on the inner side of the side plate via a mirror bearing housing, which is fixed to the side plate by bolts.

[0013] Preferably, the portion of the connecting rod and the rotating shaft located on the outer side of the side plate is fixedly connected by a keyway, and the unpowered pulley is rotatably mounted on the end of the connecting rod via a bearing.

[0014] Preferably, the screw holes on the side plate are evenly distributed along its upper and lower edges.

[0015] Preferably, the outer circumferential surface of the unpowered pulley is an arc shape or a planar structure.

[0016] Preferably, the unpowered pulley is made of nylon or polyurethane material.

[0017] The design scheme proposed in this utility model has the following beneficial effects in application:

[0018] 1. This solution uses bolts to fasten the double earring support to the side plate and a pin hinge design between the earring mounting part and the support to build a stable installation foundation. The hinge structure allows the cylinder to swing adaptively during movement, effectively absorbing the stress caused by installation errors and off-center loads, and significantly reducing rigid impact and wear between components.

[0019] 2. As described in 1, the Y-shaped pin-connected rod is used to connect the cylinder piston rod and the rotating shaft with a movable pin, which enhances the stability and reliability of force transmission. The Y-shaped structure provides multi-directional constraints, improves the force distribution, and avoids excessive stress at a single point. The movable pin facilitates disassembly and maintenance, while providing a certain degree of freedom to adapt to motion deviations under different working conditions.

[0020] 3. As described in section 2, the rotating shaft is fixed to the side plate by a mirror-symmetrically arranged bearing housing, forming a symmetrical support structure. This effectively suppresses the shaft's skew and vibration during rotation, improving rotational accuracy and overall rigidity. Combined with the keyway-connected connecting rod and the bearing-supported unpowered pulley, efficient torque transmission and low-friction motion are achieved, allowing the smoke box to transition smoothly during adjustment and avoiding surface damage. This design is suitable for high-speed reciprocating motion scenarios, improving adjustment quality and overall equipment performance. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example 1

[0027] Reference Figures 1-3 A non-standard cigarette box posture adjustment mechanism includes a side plate 4. A double-ear ring support 1 is fixedly installed on the inner side of the side plate 4 by screws and nuts. An ear ring mounting part 2 is hinged to the double-ear ring support 1. A cylinder 3 is fixedly installed on the ear ring mounting part 2. A Y-shaped pin connecting rod 5 is connected to the piston rod end of the cylinder 3. The other end of the Y-shaped pin connecting rod 5 is connected to the part of the rotating shaft 8 located on the inner side of the side plate 4 by a movable pin. The rotating shaft 8 is fixedly installed on the inner side of the side plate 4 by a mirror bearing seat 9. A connecting rod 6 is fixedly connected to the part of the rotating shaft 8 located on the outer side of the side plate 4. A non-powered pulley 7 is rotatably installed on the connecting rod 6. Screw holes for fixing the entire mechanism to the cigarette conveying line are provided on the upper and lower edges of the side plate 4.

[0028] The double earring support 1 and the side plate 4 are fastened together by bolts, and the earring mounting part 2 and the double earring support 1 are hinged together by a pin, providing a stable mounting base. The hinge design allows the cylinder to swing adaptively within a certain range, reducing stress concentration caused by installation errors or off-center loads during movement, and improving the durability and smoothness of the mechanism.

[0029] One end of the Y-shaped pin-connecting rod 5 is connected to the piston rod of the cylinder 3 by a thread or pin, and the end of the Y-shaped pin-connecting rod 5 away from the cylinder 3 is connected to the rotating shaft 8 by a movable pin. The Y-shaped structure enhances the stability of the connection and the efficiency of force transmission. The movable pin design facilitates disassembly and maintenance, while allowing a certain degree of freedom of adjustment to adapt to the motion requirements under different working conditions, thereby improving the adaptability and maintainability of the mechanism.

[0030] The rotating shaft 8 is mounted on the inner side of the side plate 4 via a mirror bearing seat 9. The mirror bearing seat 9 is fixed to the side plate 4 with bolts. The mirror arrangement of the bearing seats ensures symmetrical support of the rotating shaft, effectively preventing the shaft from tilting and vibrating during movement, improving rotational accuracy and overall rigidity of the mechanism, and is suitable for high-speed and high-frequency reciprocating motion scenarios.

[0031] The connecting rod 6 and the rotating shaft 8 located on the outside of the side plate 4 are fixedly connected by a keyway. The non-powered pulley 7 is rotatably installed at the end of the connecting rod 6 through a bearing. The keyway connection provides reliable torque transmission and prevents the connection from loosening. The non-powered pulley supported by the bearing reduces frictional resistance, allowing the smoke box to transition smoothly during adjustment, avoiding scratches on the surface of the smoke box, and improving the adjustment quality and equipment life.

[0032] Among them, the screw holes on the side plate 4 are evenly distributed along its upper and lower edges. The evenly distributed screw holes facilitate flexible installation and fine-tuning of the position according to the different width specifications of the conveyor line, which enhances the versatility and on-site adaptability of the mechanism and simplifies the installation process.

[0033] Among them, the outer circumference of the non-powered pulley 7 is either arc-shaped or flat. The arc-shaped design is suitable for guiding the smoke box to turn smoothly and reducing impact, while the flat structure is suitable for providing stable support and preventing the smoke box from tipping over. Selecting the appropriate pulley surface shape according to different application scenarios can optimize the attitude adjustment effect and the scope of application.

[0034] Among them, the non-powered pulley 7 is made of nylon or polyurethane. Nylon has good wear resistance and light weight, making it suitable for high-speed and light-load scenarios. Polyurethane has good elasticity and impact resistance, making it suitable for heavy-load or impact-prone working conditions. Both materials have the advantages of low noise and no damage to the surface of the smoke box, which improves the overall performance and applicability of the equipment.

[0035] In practice

[0036] This solution uses the telescopic motion of cylinder 3 as the core driving source. The piston rod of cylinder 3 outputs linear thrust or pull force, which pushes the Y-shaped pin connecting rod 5 to produce displacement. The Y-shaped pin connecting rod 5 is connected to the rotating shaft 8 through a movable pin, which converts the linear motion into the rotational motion of the rotating shaft 8. The rotating shaft 8 is stably supported on the inner side of the side plate 4 through the mirror bearing seat 9. The symmetrical arrangement of the bearing seats ensures the balance and accuracy of the rotating shaft 8 during rotation, avoiding uneven load or jamming. Finally, the rotational motion is transmitted to the connecting rod 6 on the outer side of the side plate 4 through the keyway connection, which drives the unpowered pulley 7 to deflect at an angle, thereby applying a guiding or adjusting force to the tobacco box passing through, realizing the active adjustment of the tobacco box's posture.

[0037] The posture adjustment function is achieved by the contact between the non-powered pulley 7 and the surface of the tobacco box. The non-powered pulley 7 is rotatably mounted on the end of the connecting rod 6 through a bearing. Its arc-shaped or flat outer circumference can adapt to the surface shape of the tobacco box. It rolls rather than slides when in contact, reducing friction and surface damage. The connecting rod 6 is fixedly connected to the rotating shaft 8, which transmits the torque generated by the cylinder 3 to the pulley. When the cylinder 3 drives the rotating shaft 8 to rotate through the Y-shaped pin connecting rod 5, the connecting rod 6 drives the non-powered pulley 7 to rotate around the shaft, changing its angle and position, thereby pushing, straightening or turning the tobacco box to ensure that the tobacco box maintains the predetermined posture and path on the conveyor line.

[0038] The double earring support 1 is fastened to the side plate 4 with bolts to provide a stable base, while the earring mounting part 2 is hinged to the double earring support 1 with a pin, allowing the cylinder 3 to swing adaptively during movement to compensate for installation errors or movement bias. The Y-shaped pin connecting rod 5 is connected to the rotating shaft 8 with a movable pin, which is convenient for disassembly and maintenance and provides a certain degree of freedom to adapt to movement deviations. The screw holes evenly distributed on the upper and lower edges of the side plate 4 support the flexible installation and position fine adjustment of the entire mechanism according to the different width specifications of the conveyor line, improving versatility.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
