Description

Technical Field

[0001] This utility model relates to the field of end-to-end splicing technology for cigarette conveyor chain plates, and in particular to an auxiliary splicing tool for cigarette conveyor chain plates. Background Technology

[0002] Currently, chain conveyors are widely used in cigarette pack conveying equipment in the tobacco industry, serving as a key transmission component and undertaking an important process in cigarette pack conveying. During the conveying process, the chain plates of a single cigarette pack conveyor can be tens or even hundreds of meters long, and frequently experience chain plate stretching deformation, chain plate wear, and chain plate link wear and breakage. Therefore, regular maintenance of the conveyor chain plates is required, replacing or repairing any worn or broken chain plates. After replacement or repair, the two ends of the conveyor chain plate need to be connected. Due to the certain tension requirements for the installation length of the conveyor chain plate, a certain tension needs to be applied to the joint of the two chain plates when they are joined. Currently, this is often achieved by using a rotating motor or manually pulling with a traction rope to align the two ends of the chain plate for installing the pin.

[0003] In actual maintenance and assembly, since the motors are fixedly installed and difficult to move to the vicinity of the chain plate assembly point, manual pulling is more common. However, manual pulling requires multiple people to work together, which results in high labor intensity for the workers, low assembly efficiency, and long time, thus having a significant impact on the efficiency of cigarette production.

[0004] Utility model patent application number 202022643356.0 discloses a chain plate joint docking device. This utility model includes a docking assembly and a support base. In use, two chain plate joints are suspended on a first hook and a second hook, respectively. Powered by a motor, the motor rotates an adjusting bolt clockwise, causing the adjusting base to move the second hook closer to the first hook until the holes of the two chain plate joints align. This utility model uses hooks to engage the chain plates, thus moving them. During this process, friction between the chain plates and the hooks can cause wear and damage to the chain plates. Furthermore, the device is powered by a motor and requires an external power source. The support base makes the entire device too large, failing to meet the needs of various usage scenarios.

[0049] To make the technical means, inventive features, objectives, and effects of this utility model readily understandable, the technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0050] like Figure 1-3 As shown, an auxiliary tool for attaching cigarette packs to a conveyor chain includes:

[0051] The fixing bracket 1 is installed in the groove at the left end of the rotating screw 3 by means of the snap-fit ​​part 6. The bottom side of the snap-fit ​​part 6 is provided with a threaded through hole. After the snap-fit ​​is completed, the flat head screw 602 is inserted into the threaded through hole, thereby locking the fixing bracket 1 in the longitudinal direction.

[0052] The movable frame 2 is threadedly mounted on the threaded rod on the right side of the rotating screw 3 via a tension sleeve 13. The end face of the tension sleeve 13 is provided with a hole 1301 for inserting the slender rod 603 of the snap-fit ​​6, thereby restricting the rotational movement of the movable frame 2.

[0053] A rotating screw 3 is provided, and a rotating handle 301 is fixedly welded to the right side of the rotating screw 3 for manually controlling the left and right movement of the movable frame 2. A connecting hole 302 is provided on the right end face of the rotating screw 3 for connecting external rotating equipment.

[0054] like Figure 4 As shown, the fixed frame 1 includes: a connecting plate 4, a movable plate 5, a snap-fit ​​component 6, a round rod 7, a spacer rod 8, and a positioning pin 11. The connecting plate 4 and the movable plate 5 have a groove-shaped structure, and a threaded hole I 401 is provided at the center of the rounded chamfer at the top. The threaded hole I 401 connects to the threaded section of the positioning pin 11 to ensure that the positioning pin 11 remains stable in the working state and will not easily fall off. A hexagonal nut 601 is welded to the top of the snap-fit ​​component 6, and a locking screw 604 is provided on the top of the hexagonal nut 601. A slender rod 603 is symmetrically provided on the right end face of the snap-fit ​​component 6 for connecting the movable frame 2. The round rod 7 has threads on its end face. The cylindrical rod with holes connects and assembles the connecting plate 4 and the movable plate 5 into one piece through screws 9 and threaded rods 10, which is used to stabilize the connecting plate 4 and the movable plate 5; the spacer rod 8 is used in conjunction with the hexagonal nut 601. The spacer rod 8 can be threaded into the threaded hole of the hexagonal nut 601 and moved left and right for adjustment. After the spacer rod 8 is adjusted to the position, tightening the locking screw 604 can ensure that the spacer rod 8 always stays in a fixed position in the working state; the positioning pin 11 is set in the threaded hole I 401 and the threaded hole II 501, and the extended part is inserted into the pin hole of the cigarette conveying chain plate 12, which is used to fix the position of the first section of the cigarette conveying chain plate 12 and keep it stable.

[0055] like Figure 5 As shown, the movable frame 2 includes: a connecting plate 4, a movable plate 5, a round rod 7, a spacer rod 8, a positioning pin 11, and a tensioning sleeve 13. The installation principle and function of the connecting plate 4, the movable plate 5, the round rod 7, the spacer rod 8, and the positioning pin 11 are the same as those of the corresponding parts of the fixed frame 1. The tensioning sleeve 13 is provided with an internal thread that matches the thread of the rotating screw 3, and can drive the movable frame 2 to move laterally left and right as the rotating screw 3 rotates. The top of the tensioning sleeve 13 is provided with a hexagonal nut 601 and a locking screw 602 for adjusting the position of the fixed spacer rod 8.

[0056] like Figure 6-7 As shown, the fixed frame 1 and the movable frame 2 can be adjusted in distance with the spacer rod 8 as the rotation axis. The distance can be adjusted according to the needs of different usage scenarios. After the adjustment is completed, the locking screw 602 can be tightened to lock it, thereby ensuring that the subsequent work remains stable. The movable plate 5 is sleeved on the end face of the round rod 7 and the spacer rod 8 by the screw 10, and together with the connecting plate 4, it clamps and stabilizes the cigarette conveying chain plate 12. The distance between the movable plate 5 and the connecting plate 4 is determined according to the width of the cigarette conveying chain plate 12.

[0057] like Figure 8-10 As shown, during operation, after adjusting the tilt angles of the fixed frame 1 and the movable frame 2 to the actual position, tighten the locking screw 604 to fix them. Rotate the screw 10 to move the movable plate 5 away from the connecting plate 4, increasing the distance between them. Then, manually pull the first end of the cigarette conveying chain plate 12 to place the first chain plate at the first end within the distance between the movable plate 5 and the connecting plate 4. Then, adjust the positioning pin 11 on the top of the connecting plate 4 to insert into the pin hole at the tail of the first chain plate at the first end. Rotate the screw 10 in the opposite direction to move the movable plate 5 close to the side of the first chain plate 12 at the first end. Adjust the positioning pin 11 at the top of the movable plate 5 and insert it into the opposing pin hole at the tail of the first chain plate. Continue to tighten the screw 10 so that the movable plate 5 and the connecting plate 4 clamp the first chain plate of the cigarette conveying chain plate 12. Then, follow the above steps to insert the positioning pin 11 at the top of the movable frame 2 into the pin hole at the head of the first chain plate at the tail end of the cigarette conveying chain plate 12, and tighten the screw 10 to clamp the tail end of the cigarette conveying chain plate 12. At this time, the first and tail ends of the cigarette conveying chain plate 12 are connected and restricted by the auxiliary connection tool to form a downward V-shaped state. Then, the operator manually rotates the rotating screw 3. Rotating screw 3 causes the movable frame 2 to gradually approach the fixed frame 1, while the first and last ends of the cigarette conveyor chain 12 gradually move upwards until they are horizontal. At this point, the operator adjusts the first and last chain plates and continues rotating screw 3 until the pin hole at the head of the first chain plate at the first end aligns with the pin hole at the tail of the first chain plate at the tail end. Then, the operator stops rotating screw 3 and inserts the pin into the aligned pin hole to complete the splicing of the first and last ends of the cigarette conveyor chain 12. After completion, rotating screw 10 in the opposite direction moves the movable plate 5 away from the side of the cigarette conveyor chain 12, allowing the auxiliary device to be removed from the cigarette conveyor chain 12. When dealing with large and heavy cigarette conveyor chain 12s that require end-to-end connection, and it is difficult to manually rotate screw 3, an external rotating device can be used. Simply insert the external rotating device into the connecting hole 302 to rotate screw 3, thus completing the end-to-end connection of the cigarette conveyor chain 12.

[0058] Finally, it should be noted that the concept, specific structure, and technical effects of this utility model have been clearly and completely described above in conjunction with the embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them.

Furthermore, the connection relationship mentioned herein does not simply refer to direct connection of components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.
