Description

Technical Field

[0001] The utility model relates to the technical field of cigarette packaging machines, in particular to a hand-cranked adjustable congestion detection device for a folding turret of an FX2 type hard-box cigarette packaging machine. Background Art

[0002] In the tobacco packaging industry, the FX2 hard box packaging machine is a highly efficient and automated production equipment that is widely used in the packaging process of various tobacco products. The 703 folding turret of this model is the core component of the packaging process. During one rotation of the 703 folding turret, the small box trademark is folded and formed (see the process flow for details). Figure 1 ), its performance and stability are directly related to the quality of the final product and the efficiency of the production line.

[0003] During production, defective cigarette packs can easily clog the 703 folding turret, especially after the packs, wrapped in liner and frame paper, are fed into the folding turret at station 3 and joined with the label paper. This can cause the cigarettes, liner, and label paper to become jammed together, causing the upper half (from the middle of the pack to the flap, located on the outer circumference of the folding turret) or lower half (from the middle to the bottom, located on the inner circumference of the folding turret) of the pack to bulge, or even the entire pack to bulge. Therefore, pack integrity inspection is required at station 4 to prevent defective packs from entering subsequent processes.

[0004] However, in the existing FX2 packaging machine, although the No. 4 station of the 703 folding turret is equipped with a defective cigarette pack detection device, which can to a certain extent identify and prevent damaged cigarette packs from entering subsequent stations, there are still many shortcomings in actual application.

[0005] First, the existing mold box inspection device has a limited and non-adjustable detection range. It's designed to detect damage and congestion only at the top of the cigarette pack (i.e., where the flap is located). The inspection range doesn't fully cover the entire upper half of the pack, and the lower half isn't inspected, leaving damage, congestion, and bulges in these areas undetected. This results in damaged packs going undetected during production, leading to the bottom of the pack bulging or popping out of the folding turret mold box, causing blockages in subsequent processes and leading to a series of equipment failures and product quality issues.

[0006] Secondly, due to design flaws in the inspection system, if damaged cigarette packs are not promptly identified and removed, they could enter the gluing channel, causing the flap locator to become stuck, or even knocking the pusher off the second pusher belt, causing the 703 trademark plate at station 1 to become stuck and dislodged, seriously disrupting normal production line operation. More seriously, if the blockage caused by damaged cigarette packs is not cleared in a timely manner, it could damage the entire folding turret, increasing repair costs and significantly reducing production efficiency. Even if the blockage caused by damaged cigarette packs is minor and the machine is not immediately shut down, it could flow into the 753 small pack transparent paper packaging machine, causing packaging failures and the risk of substandard cigarette packs entering the market, resulting in unnecessary financial losses for the company.

[0007] In addition, the coverage of detection devices required for cigarette packages with different production requirements is different, and the equipment may have detection accuracy problems after long-term use. Therefore, it is often necessary to debug and adjust according to actual production.

[0008] Furthermore, considering the actual application of the production line, the adjustment of the detection device's coverage range should be controllable, easy to operate, continuous, precise, and capable of fine-tuning. Therefore, it is urgent to develop a new type of adjustable defective cigarette pack congestion detection device that can flexibly adjust the detection range to fully cover all parts of the cigarette pack, improve detection accuracy and reliability, eliminate the possibility of damaged cigarette packs flowing into subsequent processes, protect machinery from damage, and ensure production safety, production efficiency, and product quality.

[0022] Locking bolts (34), the locking bolts (34) are two groups of four, respectively used to connect the detection guide rail arm (31) and the extension arm (33), and the extension arm (33) and the connecting column (35);

[0023] Connecting columns (35), there are two connecting columns (35), which are detachably connected to the extension arm (33) via a locking bolt (34) passing through the circular hole of the extension arm (33);

[0024] The second detection guide rail (36) is arc-shaped, located below the connecting column (35), and connected to the two connecting columns (35).

[0025] As a preferred solution of the present utility model, the touch rod mechanism (4) includes:

[0035] The working principle of this utility model is:

[0036] The detection guide rail mechanism (3) of the device can fully cover the congestion detection requirements of cigarette packs in the turret mold box (A), wherein the first detection guide rail (32) is responsible for triggering the congestion detection of the upper half of the cigarette pack (i.e., from the middle of the cigarette pack to the flip cover position), and the second detection guide rail (36) is responsible for triggering the congestion detection of the lower half of the cigarette pack (i.e., from the middle of the cigarette pack to the bottom position).

[0037] Through the structural design of the detection guide rail mechanism (3) and the hand-cranked adjustment mechanism (6) of the utility model, the locking bolt (34) on the waist-shaped hole (331) is loosened, and the crank (61) is rotated clockwise or counterclockwise.

[0038] Beneficial effects of the utility model:

[0039] 1. The utility model is easy to operate and has strong controllability in adjusting the detection range: the design of the hand-crank adjustment mechanism makes it possible to easily and labor-savingly adjust the detection range of the detection device. Moreover, since the extension and retraction of the extension arm are driven by gears, this design enables the extension amount of the extension arm to be very finely controlled and adjusted continuously and precisely, thus reducing the problem of improper detection range setting due to misoperation.

[0040] 2. The utility model improves the reliability and stability of the enhanced equipment: The utility model can accurately sense the congestion of cigarette packs during the transmission process, ensuring the sensitivity and accuracy of the detection device, so as to timely discover and deal with defective cigarette packs, avoiding unnecessary accumulation and shutdown on the production line. This not only reduces the number of manual interventions, but also reduces errors and omissions caused by human factors, significantly improving production efficiency and product quality.

[0041] 3. This utility model is easy to maintain: The entire detection device adopts a modular design, and all components, including the base, connecting shaft, and detection guide mechanism, are detachable and connectable. This not only facilitates installation and commissioning, but also greatly facilitates subsequent maintenance and replacement. If a component fails or needs to be upgraded, it can be quickly replaced, reducing maintenance costs and time. BRIEF DESCRIPTION OF THE DRAWINGS

[0083] like Figure 3 、 Figure 4 As shown, before starting production, the device is first installed at the No. 4 station of the folding turret of the FX2 type cigarette packaging machine, and then the equipment is debugged.
