Abstract
Description
Technical Field
[0001] This utility model relates to a smoke protection device. Background Technology
[0002] The ZB45B packaging machine completes the final long-side folding of the cigarette pack as it moves from wheel number five to wheel number six. During operation, the push rod of wheel number six moves forward, flattening and pressing the large surface of the box lid. Then, the push rods of wheels five and six simultaneously clamp the cigarette pack through the folding channel, folding both long sides of the small box before sending it into the mold box of wheel number six. The mold box of wheel number six is equipped with cigarette guard hooks on both sides, which lock the cigarette pack securely inside after it is pushed in.
[0003] The original No. 6 wheel mold box structure includes a mold box, a cigarette guard hook, a spring, a spring seat, screws, set screws, and a pin. The cigarette guard hook is fixed in the mold box by the pin, and the spring seat is fixed to the mold box by screws. A spring is installed between the spring seat and the cigarette guard hook to ensure that the cigarette guard hook can always lock the cigarette pack. A set screw is installed at one end of the pin to ensure that the pin will not fall out of the mold box. A hole of a fixed size is opened in the middle of the mold box to ensure smooth passage of the cigarette receiving push rod.
[0004] The cigarette hook spring support is made of 2mm thick spring steel sheet. Due to insufficient strength, the spring support is prone to deformation. In actual production, deformation and jamming of the cigarette pack can cause the spring support of the cigarette hook to twist and deform inward or outward. If it deforms inward, the cigarette hook will not return to its original position during the process of pushing the cigarette pack into the six-wheel mold box. The working surface A of the cigarette hook will be higher than the working surface B of the six-wheel mold box, and the cigarette pack will be forcibly pushed into the six-wheel mold box, causing damage to the appearance of the cigarette pack, or...
[0005] Inadequate positioning can cause blockages in subsequent processes. If the cigarette pack is twisted or deformed outwards, the cigarette hook will not be able to reliably fasten to the cigarette pack in the six-wheel mold box. The cigarette pack will not be able to fit snugly against the six-wheel mold box, which will also cause scratches or blockages in the cigarette pack in subsequent processes. In severe cases, the spring may fall off, and the cigarette hook may become ineffective or even damaged.
[0006] The cigarette guard hook is a slender cylindrical pin. Due to its excessive length and thinness, disassembly is difficult when replacing worn or damaged cigarette guard hooks. A special punch is required to remove the cylindrical pin, and it is also highly susceptible to deformation. When the cigarette guard hook structure malfunctions, replacement is time-consuming and labor-intensive, severely impacting production efficiency. Summary of the Invention
[0007] The purpose of this invention is to address the shortcomings by providing a smoke protection device.
[0008] To achieve the objective of this invention, the following technical solution is adopted:
[0009] This utility model discloses a smoke protection device, comprising: a spring seat, a spring, a spring positioning pin, a smoke protection hook, a smoke protection hook support seat, and a fixing seat. The smoke protection hook support seat is U-shaped, with a fixing seat fixed in the center. A threaded hole is opened on each of the left and right sides of the fixing seat. The spring seat is fixed at the rear center of the smoke protection hook support seat and the fixing seat, perpendicular to the smoke protection hook support seat and extending upwards from it. A spring positioning pin is fixed near the upper end of the spring seat, extending into the smoke protection hook support seat. The spring positioning pin is perpendicular to the spring seat. The lower ends of the smoke protection hook are respectively mounted on the two ends of the U-shape of the smoke protection hook support seat via pins. The spring is fitted onto the spring positioning pin, with one end pressing against the spring seat and the other end pressing against the upper end of the smoke protection hook. The smoke protection hook rotates around the pin.
[0010] The smoke protection device of this utility model includes a spring fixing groove on the back of the upper end of the smoke protection hook, and the other end of the spring is stuck in the spring fixing groove.
[0011] The present invention provides a smoke protection device in which a cigarette holder is fixed on the front of the upper end of the smoke protection hook, and the included angle between the cigarette holder and the smoke protection hook is 40-50°.
[0012] The smoke protection device of this utility model, wherein: the smoke protection hook is a stepped rod, the upper section of which is outside the lower section.
[0013] The smoke protection device of this utility model is wherein the spring seat, spring positioning pin, smoke protection hook support seat and fixing seat are integrated into one structure.
[0014] The present invention relates to a smoke protection device, wherein the smoke protection hook and the cigarette holder are an integral structure.
[0015] In this utility model, a smoke protection device is provided, wherein screws pass through the two threaded holes to fix the smoke protection device onto the module.
[0016] Compared with existing smoke protection devices, the smoke protection device of this invention has the following advantages:
[0017] 1. The smoke protection device of this utility model can be reliably installed in the mold box, and the cigarette pack can be pushed to the center of the mold box, ensuring the folding quality of the small box and significantly improving the forming quality of the small pack;
[0018] 2. The reinforced spring seat made of stainless steel is strong and reliable, not easily deformed, ensuring that the cigarette hook can reliably fasten the cigarette pack in the six-wheel mold box.
[0019] 3. It adopts an integrated smoke protector hook mechanism, which is simple, convenient and quick to install and replace. Attached Figure Description
