Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for cigarette production, specifically to a chain plate section and a chain plate for a cigarette conveyor line. Background Technology

[0002] After being formed, the cigarette sticks are packaged into cartons by the packaging and sealing equipment. These cartons then travel via a carton elevator to the carton conveyor line, and from there to the box-sealing equipment, finally being packaged into cigarette boxes. The carton conveyor line plays a crucial role in the entire production line, connecting the upstream and downstream processes. It includes a power head, chain plates, steel beams, guide rails, brushes, and an electrical control system. The chain plates are composed of several linked sections, which, through sprockets, complete a cyclical movement, carrying the continuous cartons of cigarettes to the next production stage.

[0003] The existing chain plate link consists of a body, insert plates, a connecting shaft, and a slider. Two insert plates are installed in the left and right fixed blocks of the body, respectively. The slider is installed below the fixed blocks to block and limit the position of the connecting shaft, which connects the chain plate links in series. The chain plate link uses a fixed block on each side to form a sliding track with the guide rail below it. However, this also generates sliding friction. The larger the restricted area of ​​the fixed block, the greater the resistance. Over time, this causes wear on the surface of the fixed block. Simultaneously, the wear gaps fill with a large amount of dust, forming a layer of dirt on the surface of the fixed block. As the dirt accumulates, the resistance on the chain plate link increases, thus increasing the load on the power head and easily causing overload and shutdown. Utility Model Content

[0038] This utility model provides a first aspect of a chain plate link, such as... Figure 1 and Figure 2 As shown, the chain plate section includes a section body 1 and a rolling element 2.

[0039] The link body 1 includes a base plate 11 and fixing blocks disposed on both sides of the base plate 11. The base plate and the fixing blocks define a guide channel for a guide rail to pass through. Rolling elements 2 are rotatably mounted on the inner wall surfaces of the base plate 11 and the fixing blocks, and the rolling surfaces of the rolling elements 2 protrude from the inner wall surfaces of the base plate 11 and the fixing blocks to form a rolling contact surface with the guide rail. When the link is mounted on the guide rail, the link will hug the guide rail and run along the extension direction of the guide rail under the drive of the power head.

[0040] Therefore, based on the setting of rolling element 2, the traditional sliding friction is changed to rolling friction, which greatly reduces the running resistance, reduces the load on the power head and the failure rate of the equipment.

[0041] The fixing blocks include a left fixing block 12 and a right fixing block 13 symmetrically arranged on both sides of the base plate 11. The left fixing block 12 and the right fixing block 13 have left fixing block grooves 12a and 13a respectively on opposite sides. The base plate 11 has a base plate groove 11a on one end face facing the guide channel. The rolling element 2 is rotatably disposed within the left fixing block groove 12a, the right fixing block groove 13a, and the base plate groove 11a.

[0042] The rolling element 2 can be either a cylindrical roller or a ball bearing. In a preferred embodiment, the rolling element 2 is a cylindrical roller. The cylindrical rollers disposed in the left fixed block groove 12a and the right fixed block groove 13a are arranged vertically, while the cylindrical rollers disposed in the bottom plate groove 11a are arranged horizontally. Further, the axes of the cylindrical rollers disposed in the left fixed block groove 12a and the right fixed block groove 13a are perpendicular to the length direction of the guide channel in a vertical plane. The axes of the cylindrical rollers located in the bottom plate groove 11a are perpendicular to the length direction of the guide channel in a horizontal plane.

[0043] The cylindrical roller is provided with a central column 21 at both ends. The central column 21 is pivotally connected to the slot 6 provided in the left fixed block groove 12a, the right fixed block groove 13a, and the bottom plate groove 11a. That is, the central column 21 is embedded in the slot 6 in the left fixed block groove 12a, the right fixed block groove 13a, and the bottom plate groove 11a and is rotatably connected to it.

[0044] Inserts 3 are respectively embedded in the left fixing block groove 12a and the right fixing block groove 13a. The side of the insert 3 facing the fixing block groove (left fixing block groove 12a or right fixing block groove 13a) has an insert hole that mates with the central post 21. The central post 21 at one end of the cylindrical roller is embedded in the groove hole 6 of the fixing block groove, and the other end is embedded in the insert hole. The central post 21 and the insert hole are also rotatably connected.

[0045] The section body 1 also includes connecting portions located at the front and rear ends of the base plate 11 and paired with each other. Further, the connecting portions have shaft holes extending through them along the width direction of the guide channel. The left fixing block 12 and the right fixing block 13 are provided with grooves communicating with the shaft holes at positions corresponding to the shaft holes. A slider 5, capable of sliding along the extension direction of the groove, is provided within the groove. The slider 5 has a locked position and an unlocked position. In the locked position, the slider 5 partially or completely obstructs the shaft hole, achieving axial fixation of the connecting shaft 4. In the unlocked position, the slider 5 completely retracts from the shaft hole area, allowing the connecting shaft 4 to be disassembled and assembled.

[0046] In some embodiments, the segment 1 and the rolling element 2 are made of plastic. Specifically, high-strength plastics (such as polyoxymethylene, polyamide, etc.) can be used for injection molding.

[0047] like Figure 3 and Figure 4 As shown, this utility model also provides a cigarette conveyor chain plate, which is formed by connecting multiple chain plate sections end to end. Adjacent chain plate sections are connected by simultaneously inserting a connecting shaft into the shaft hole of the connecting part of the adjacent chain plate section. Typically, the connection between adjacent chain plate sections is a hinge.

[0048] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.
