Description

Technical Field

[0001] The utility model relates to the technical field of cylinder equipment, in particular to an automatic pressurization auxiliary structure for a roller cylinder. Background Art

[0002] Support rollers play a crucial role in the production of plastic films. Their primary function is to support and guide the film, ensuring smooth and accurate movement along the production line. By controlling film tension and flatness, support rollers have a direct impact on film quality and production efficiency. Tension control is crucial for preventing wrinkles, curling, or breakage during the production process, while flatness directly impacts the film's final appearance and performance.

[0003] Precise positioning and pressure regulation of the support rollers are equally important for uniform film cooling, stretching, and shaping. On high-speed production lines, support rollers also help reduce material vibration and oscillation, improving line stability. Furthermore, the design and layout of the support rollers can impact the accuracy and effectiveness of subsequent film processing, such as printing, coating, or lamination.

[0004] However, in actual production, the stable operation of the support roller may be affected by various factors. Among them, the reliability of the cylinder drive is crucial to ensuring the proper function of the support roller. The cylinder provides power to control the position and pressure of the support roller, thereby achieving precise adjustment of film tension. However, if the pressure in the cylinder line is insufficient, the support roller may not operate properly, resulting in a failure in film tension control. This can cause film runaway, causing equipment downtime, and impacting production efficiency and product quality.

[0005] In some cases, equipment design flaws can result in poor exhaust flow from the solenoid valve, impacting the proper functioning of the cylinder. The solenoid valve is a critical component in controlling the cylinder's movement. If exhaust flow is poor, internal pressure in the cylinder cannot be released quickly, preventing the roller from responding to control signals, resulting in sluggish or complete inaction. This situation not only reduces production efficiency but can also lead to defective products due to improper tension control, increasing production costs.

[0006] In response to the above problems, it is urgent to carry out innovative design based on the original cylinder pipeline. Utility Model Content

[0007] The technical solution of the present invention aims at the technical problem that the existing technical solution is too single, and provides a solution that is significantly different from the existing technology in the automatic pressurization auxiliary structure of the roller cylinder to solve the problems raised in the above background technology.

[0008] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: an automatic pressurization auxiliary structure of a roller cylinder, comprising a tube body, the outer wall of the tube body is connected to a box body, and the box body is provided with a monitoring structure that is activated according to the decrease in air pressure in the tube body, the tube body is provided with a power storage structure that cooperates with the monitoring structure, and a guide structure for cooperating with the monitoring structure and the power storage structure is installed in the tube body.

[0009] Preferably, the monitoring structure includes an adjusting screw, a plate, an adjusting spring, a magnetic trigger frame, and a magnetic block. The box body is connected to the adjusting screw, and the adjusting screw is located in the box body and is rotatably connected to the plate body at the end thereof. The plate body is connected to the adjusting spring, and the end of the adjusting spring is connected to the magnetic trigger frame, and both ends of the magnetic trigger frame are located in the tube body, and the tube body is slidably connected to the magnetic block in the area below the box body.

[0010] Preferably, the magnetic trigger frame is configured as a "concave" structure, and the side surface of the magnetic trigger frame away from the power storage structure is configured as an inclined surface, and the magnetic poles of the magnetic trigger frame and the magnetic block are the same.

[0011] Preferably, the force storage structure includes a fan blade disk, a connecting shaft, a full gear, a concave block, a concave frame, a vortex spring, an L-shaped plug rod, and an insert block. A fan blade disk is provided in the tube body, and a connecting shaft is connected to the fan blade disk. The end of the connecting shaft passes through the outer wall of the tube body and is located on the concave block, and the concave block is connected to the concave frame, and the concave frame is connected to the outer wall of the tube body. A vortex spring is connected between the concave block and the end of the connecting shaft. The connecting shaft is located on the outer wall of the tube body and is connected to the full gear, and an insert block is engaged with the side of the full gear. The insert block passes through the engaging and sliding connection to the L-shaped plug rod, and a spring for reset is connected between the insert block and the L-shaped plug rod, and the L-shaped plug rod is engaged and slidably connected to the outer wall of the box body.

[0012] Preferably, the outer gear block of the full gear is configured as a helical gear block, and the side of the end portion where the insert block contacts the full gear is configured as a bevel.

[0013] Preferably, the guide structure includes a fixed plate, a movable plate, a limiting spring, and an auxiliary magnetic block. The fixed plate is connected to the inside of the tube body, and the end of the fixed plate is rotatably connected to the movable plate, and a limiting spring is connected between the outer wall of the movable plate and the inner wall of the tube body.

[0014] Preferably, the fixed plate is arranged directly below the fan blade disk, and the end surface of the movable plate is in contact with one end of the magnetic trigger frame.

[0015] Compared with the existing technology, the beneficial effects of this utility model are as follows: the roller cylinder automatic boost auxiliary structure, by installing a tube body between the solenoid valve and the pipeline, triggers the force storage structure in the tube body when the cylinder performs the return stroke, and the fan disc rotates clockwise, beginning to accumulate energy. This process is similar to the compression of a spring or the lifting of a heavy object, storing potential energy for subsequent use. When the cylinder enters the output stroke stage, due to some reason, the air pressure in the pipeline is insufficient, and it cannot provide sufficient power to propel the cylinder to complete its stroke. At this time, our monitoring structure comes into play.

[0016] The monitoring mechanism is sensitive to insufficient air pressure. Once it detects a drop in pressure that's insufficient to push the magnetic trigger, it triggers the energy storage mechanism to release previously stored energy. This force drives the fan disc counterclockwise, increasing the flow rate and pressure of the gas within the tube. This boosting effect effectively compensates for the lack of air pressure, ensuring the cylinder receives sufficient power to complete its output stroke.

[0017] This pressurization mechanism allows the cylinder to overcome momentary pressure fluctuations, ensuring precise movement and positioning of the rollers, thereby maintaining the continuity and stability of the production line. This innovative design not only improves the efficiency of the cylinder but also enhances the reliability and adaptability of the entire system, allowing it to maintain efficient operation despite uncertainties such as air pressure fluctuations.

Both ends of the magnetic trigger frame 304 are located inside the tube body 1, and the magnetic block 305 is slidably connected to the area below the box body 2 in the tube body 1.

[0027] The magnetic trigger frame 304 is configured as a concave structure, and the side surface of the magnetic trigger frame 304 away from the power storage structure 4 is configured as an inclined surface, and the magnetic poles of the magnetic trigger frame 304 and the magnetic block 305 are the same.

[0028] The power storage structure 4 includes a fan blade disc 401, a connecting shaft 402, a full gear 403, a recessed block 404, a recessed frame 405, a vortex spring 406, an L-shaped plug rod 407, and an insert block 408. The fan blade disc 401 is provided in the tube body 1, and the fan blade disc 401 is connected to the connecting shaft 402. The end of the connecting shaft 402 passes through the outer wall of the tube body 1 and is located in the recessed block 404. The recessed block 404 is connected to the recessed frame 405, and the recessed frame 405 is connected to the tube body 1. A vortex spring 406 is connected between the outer wall of the body 1, the concave block 404 and the end of the connecting shaft 402. The connecting shaft 402 is located on the outer wall of the tube body 1 and is connected to a full gear 403. An insert block 408 is engaged with the side of the full gear 403. The insert block 408 is connected to the L-shaped insert rod 407 through the engagement and sliding connection. A spring for resetting is connected between the insert block 408 and the L-shaped insert rod 407, and the L-shaped insert rod 407 is engaged and slidably connected to the outer wall of the box body 2.

[0029] The outer gear block of the full gear 403 is configured as a helical gear block, and the end portion of the insert block 408 that contacts the full gear 403 is configured as an inclined surface.

[0030] The guide structure 5 includes a fixed plate 501, a movable plate 502, a limiting spring 503, and an auxiliary magnetic block 504. The fixed plate 501 is connected to the inside of the tube body 1, and the end of the fixed plate 501 is rotatably connected to the movable plate 502, and a limiting spring 503 is connected between the outer wall of the movable plate 502 and the inner wall of the tube body 1. The inner wall of the tube body 1 is provided with an auxiliary magnetic block 504 that fits with the movable plate 502.

[0031] The fixed plate 501 is located directly below the fan disc 401 , and the end surface of the movable plate 502 is in contact with one end of the magnetic trigger frame 304 .

[0032] Working principle: According to Figure 3 As shown, when the cylinder performs the output stroke, the airflow enters the tube body 1. When the air pressure is sufficient, the magnetic trigger frame 304 is squeezed to move into the box body 2, and the end of the movable plate 502 is in contact with the auxiliary magnetic block 504. The airflow drives the roller through the pipeline;

[0033] Figure 1 As shown, during the return stroke, the airflow passes through the diverter portion of the fixed plate 501, driving the impeller disc 401 to rotate clockwise, driving the connecting shaft 402 and the full gear 403 to rotate. The concave block 404 and the concave frame 405 cooperate to store force in the vortex spring 406. Since the inclined surface of the helical tooth block of the clockwise rotating full gear 403 contacts the inclined surface of the insert block 408, there is no limit engagement. If the vortex spring 406 is to reset and drive the full gear 403 to rotate counterclockwise, the right-angled surface of the insert block 408 is engaged with the right-angled surface of the helical tooth block on the full gear 403 to limit the position.

[0034] according to Figure 2As shown, when the air pressure is insufficient, although the air pressure of this part of the air flow is insufficient, the air flow can still push the magnetic block 305 to move and be misaligned with the magnetic trigger frame 304. At this time, due to insufficient air pressure and the magnetic trigger frame 304 is not affected by the magnetic repulsion of the magnetic block 305 of the same polarity, the end of the magnetic trigger frame 304 enters the tube body 1, pushing the movable plate 502 to rotate and open. At the same time, the movement of the magnetic trigger frame 304 attracts and drives the L-shaped plug 407 of the opposite magnetic force on the outer wall of the box body 2 to move downward, and the plug 408 on the L-shaped plug 407 is disengaged from the full gear 403. The vortex spring 406 resets and drives the connecting shaft 402 and the fan blade disk 401 to rotate counterclockwise, promoting the rapid flow of air in the tube body 1, similar to the water pump acting on the water in the water pipe, achieving a certain boosting effect. This is the working principle of the automatic boosting auxiliary structure of the roller cylinder.

[0035] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
