Description

Technical Field

[0001] This invention relates to the field of adhesive cooling line production technology, and more specifically, to an adhesive cooling line air box and control method. Background Technology

[0002] In the intensive mixing process of rubber tires and products, the production process involves weighing and proportioning rubber compounds, carbon black, oils, and various chemical additives, followed by intensive mixing, extrusion, sheeting, stacking, and transfer to the next process. During the sheeting and stacking stages, the rubber sheets require spraying a release agent and undergoing cooling and drying. This is achieved through a rubber cooling line, which works by equipping its airbox with numerous cooling fans. These fans blow away residual liquids and high-temperature steam adhering to the rubber sheets, simultaneously cooling the sheets.

[0003] Currently, the cooling fan control design requires that before production operation, the operator first turns on all the cooling fans in the air box. Then, the front-end equipment extrudes the film, which is then transferred and sprayed with a release agent before entering the air box. The cooling fans in the air box dry and cool the film, and finally the film reaches the equipment at the back end of the air box.

[0004] Inside the glue-cooling line's air box, the following production scenarios exist: First, in the initial stage of production, the film either hasn't entered the air box or is only present at the front end. Second, in the later stages of production, the film is only present at the rear end of the air box. Third, the previous batch of film has been processed, but the next batch hasn't started processing. In all three scenarios, there are areas inside the glue-cooling line's air box without film, yet the cooling fans in these areas continue to operate. This prolonged ineffective operation of the cooling fans results in significant energy waste and increases production costs.

[0005] In addition, the start and stop of the cooling fans are entirely manual, which may lead to production accidents due to untimely opening and closing of the cooling fans, as well as film quality problems and greater energy waste.

[0006] Therefore, how to improve the automation level of the glue cooling line air box and save production energy is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0007] In view of this, the first objective of the present invention is to provide a glue cooling line air box that can improve the automation level of the glue cooling line air box and save production energy.

[0008] The second objective of this invention is to provide a method for controlling the air box of a glue cooling line.

[0009] To achieve the first objective mentioned above, the present invention provides the following solution:

[0012] The film hanging rod is located on the air outlet side of the cooling fan unit and is used to hang the film.

[0013] The rod position detection element is located at the rear end of the bellows and is used to detect the distance between the film rod and the front end of the bellows.

[0014] Multiple film hanging rods are arranged in sequence to form a hanging rod chain, and the hanging rod chain can move from the front end to the rear end of the bellows.

[0015] Preferably, the above-mentioned glue cooling line air box further includes an inlet detection element, which is arranged at the front end of the air box and is used to detect whether there is film on the film hanging rod at the front end of the air box.

[0018] Preferably, the above-mentioned air box for the cooling line also includes a film inlet and a film outlet, with the film inlet located at the front end of the air box and the film outlet located at the rear end of the air box.

[0019] Preferably, in the above-mentioned glue cooling line air box, the cooling fan unit includes one or more cooling fans.

[0020] To achieve the second objective mentioned above, the present invention provides the following solution:

[0021] A method for controlling a glue cooling line air box, used for drying and cooling film, employing any of the above-mentioned glue cooling line air boxes, the method comprising:

[0022] Step S1: The film hanging rod hangs the film and moves it from the front end to the rear end of the bellows;

[0023] Step S2: The rod position detection element detects the distance S between the film rod and the front end of the bellows in real time;

[0024] Step S3: The cooling fan unit, located at a distance L-S from the rear end of the wind box, is turned on, with the length of the wind box being L.

If so, the film hanger is marked as having a film signal and the process proceeds to step S1. Otherwise, the inlet detection element continues to detect the next film hanger.

[0026] Preferably, in the above-described method for controlling the air box of the glue cooling line, step S5 is further included after step S3: after the rear-end detection element detects the presence of film on the film hanger at the rear end of the air box, it clears the presence of film signal on the film hanger.

[0027] Preferably, in the above-mentioned method for controlling the air box of the adhesive cooling line, multiple film hanging rods are arranged sequentially to form a hanging rod chain, which forms a closed loop and moves cyclically along the air box.

Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without novelty are within the scope of protection of the present invention.

They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the indicated position or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations of the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0037] like Figures 1-3 As shown, the present invention provides a film cooling line air box for drying and cooling films, including a cooling fan unit 100, film hanging rods 200, and a hanging rod position detection element 300. The cooling fan unit 100 is arranged sequentially inside the air box for cooling the films. The film hanging rods 200 are arranged on the air outlet side of the cooling fan unit 100 for hanging the films. The hanging rod position detection element 300 is arranged at the rear end of the air box for detecting the distance S between the film hanging rods 200 and the front end of the air box. Multiple film hanging rods 200 are arranged sequentially to form a hanging rod chain, and the hanging rod chain can move from the front end to the rear end of the air box. In use, the film hanging rod 200 hangs the film to be dried and cooled, and moves from the front end to the rear end of the air box. The hanging rod position detection element 300 detects the distance S between the film hanging rod 200 and the front end of the air box in real time. Let the length of the air box be L. When the film hanging rod 200 moves, the cooling fan unit 100 arranged at a distance L-S from the rear end of the air box is turned on to cool the film. Multiple film hanging rods 200 are arranged in sequence to form a hanging rod chain. The hanging rod chain moves from the front end to the rear end of the air box. The cooling fan unit 100 turns on and off accordingly according to the real-time detection of the hanging rod position detection element 300, realizing the automatic opening and closing of the cooling fan unit 100, improving the automation level of the air box and saving production energy.

[0038] To optimize the above technical solution, the adhesive cooling line air box also includes an inlet detection element 400. The inlet detection element 400 is arranged at the front end of the air box and is used to detect whether there is film on the film hanging rod 200 located at the front end of the air box. Specifically, in some embodiments of the present invention, the inlet detection element 400 detects whether there is film on the film hanging rod 200 by material detection. That is, when the film hanging rod 200 enters the detection range of the inlet detection element 400, if the inlet detection element 400 detects the target material, it confirms that there is film and marks the film hanging rod 200 with adhesive. If the inlet detection element 400 does not detect the target material, it confirms that there is no film and continues to detect the next film hanging rod 200. In other embodiments of the present invention, the inlet detection element 400 detects the presence of film on the film holder 200 by shape detection. That is, when the film holder 200 enters the detection range of the inlet detection element 400, if the inlet detection element 400 detects the target shape, it confirms the presence of film and marks the film holder 200 with adhesive. If the inlet detection element 400 does not detect the target shape, it confirms the absence of film and continues to detect the next film holder 200. It is understood that the inlet detection element 400's detection method for the presence of film on the film holder 200 includes, but is not limited to, material detection and shape detection.

[0039] In use, the film hanging rod 200 passes through the inlet detection element 400 at the front end of the air box. After the inlet detection element 400 detects and confirms that there is film on the film hanging rod 200, it marks the film hanging rod 200. Then, the film hanging rod 200 moves from the front end to the rear end of the air box. The hanging rod position detection element 300 detects the distance S between the film hanging rod 200 and the front end of the air box in real time. Let the length of the air box be L. When the film hanging rod 200 moves, the cooling fan unit 100 arranged at a distance L-S from the rear end of the air box is turned on to cool the film. By arranging the inlet detection element 400, it is possible to more accurately determine whether there is film on the film hanging rod 200. This allows the hanging rod position detection element 300 to perform real-time detection on the position of the film hanging rod 200 where film is present. At the same time, it can reduce the workload of the hanging rod position detection element 300, so that it does not need to perform real-time detection on every film hanging rod 200. This improves the automation level of the glue cooling line air box and saves production energy of the glue cooling line.

[0040] To optimize the above technical solution, the cooling line air box also includes a rear-end detection element 500. The rear-end detection element 500 is located at the rear end of the air box and is used to remove film markings from the film hangers 200. Specifically, the film hanger 200 is detected by the rear-end detection element 500. In use, when the film hanger 200 enters the detection area of ​​the rear-end detection element 500, if the film hanger 200 does not have a film marking, it continues to detect the next film hanger 200. If a film marking exists on the film hanger 200, the film marking is removed, and the hanger position detection element 300 stops real-time detection of the film hanger 200 whose film marking has been removed. The corresponding cooling fan unit 100 also stops operating, and the film hanger 200 continues to move to the next position. By arranging the back-end detection element 500, the real-time detection of the film hanging rod 200 where the film has been dried and cooled by the hanging rod position detection element 300 can be stopped. This can save the workload of the hanging rod position detection element 300, realize the accurate detection of the position of the film hanging rod 200 by the hanging rod position detection element 300, and improve the automation level of the glue cooling line air box.

[0041] To optimize the above technical solution, the cooling line air box also includes a contactor, which is electrically connected to the cooling fan unit 100 and used to control the opening and closing of the cooling fan unit 100. Specifically, the contactor is electrically connected to the hanging rod position detection element 300. In use, assuming the length of the air box is L, after the hanging rod position detection element 300 detects a distance S between the film hanging rod 200 with film markings and the front end of the air box, it transmits a signal to the contactor in real time. The contactor controls the cooling fan unit 100 located at a distance L-S from the rear end of the air box to open, and the remaining cooling fan units 100 to close. This process continues as the film hanging rod 200 moves until the film markings on the film hanging rod 200 disappear. By arranging contactors, the cooling fan unit 100 can be controlled in real time. Based on whether there is an adhesive mark on the film hanging rod 200 corresponding to the cooling fan unit 100, the opening and closing of the cooling fan unit 100 can be controlled, realizing the automation of the glue cooling line air box, saving manpower, achieving energy saving, and reducing production costs.

[0042] To optimize the above technical solution, the adhesive cooling line air box also includes a film inlet 600 and a film outlet 601. The film inlet 600 is located at the front end of the air box, and the film outlet 601 is located at the rear end of the air box. Specifically, the inlet detection element 400 is located close to the film inlet 600, and the rear detection element 500 is located between the cooling fan unit 100 and the film outlet 601 at the rear end of the air box. In use, the film enters through the film inlet 600 and is hung on the film hanging rod 200. The film hanging rod 200 moves from the front end to the rear end of the air box. During the movement, the cooling fan unit 100 at the position corresponding to the film is turned on to dry and cool the film. When the film hanging rod 200 moves to the rear end of the air box, the rear detection element 500 removes the film markings on the film hanging rod 200. The film hanging rod 200 continues to move to the film outlet 601, where the film leaves the film hanging rod 200 and exits the air box from the film outlet 601.

[0043] To optimize the above technical solution, the cooling fan unit 100 of the adhesive cooling line air box includes one or more cooling fans. Specifically, the number of cooling fans included in the cooling fan unit 100 can be arranged according to different processing requirements and processes for the film. In use, when the cooling fan unit 100 includes one cooling fan, the contactor controls the cooling fan one-to-one; when the cooling fan unit 100 includes multiple cooling fans, the contactor controls the cooling fans one-to-many. The cooling fan units 100 are arranged sequentially from the front to the rear of the air box to dry and cool the components of the film. Similarly, the contactor can adjust the working intensity of the cooling fan unit according to different processing requirements of the film to adapt to various situations. This arrangement can adapt to different working conditions, achieving both automated production and energy saving.

[0044] like Figure 3 As shown, the present invention provides a method for controlling a glue cooling line fan box for drying and cooling film, using any of the glue cooling line fan boxes described above. The glue cooling line fan box control method includes:

[0045] Step S1: The film hanging rod 200 hangs the film and moves it from the front end to the rear end of the bellows;

[0046] Step S2: The rod position detection element 300 detects the distance S between the film rod 200 and the front end of the bellows in real time;

[0047] Step S3: The cooling fan unit 100, located at a distance L-S from the rear end of the wind box, is turned on. The length of the wind box is L.

[0048] To optimize the above technical solution, step S4 is included before step S1: the inlet detection element 400 detects whether there is film on the film hanging rod 200 located at the front end of the wind box. If so, it marks the film hanging rod 200 as having a film signal and proceeds to step S1. Otherwise, the inlet detection element 400 continues to detect the next film hanging rod 200.

[0049] To optimize the above technical solution, step S5 is added after step S3: the back-end detection element 500 detects the presence of film on the film hanger 200 located at the rear end of the air box and then clears the presence signal of film on the film hanger 200. To optimize the above technical solution, multiple film hangers 200 are arranged sequentially to form a hanger chain and form a closed loop, moving cyclically along the air box. Specifically, after the film on the film hanger 200 leaves the air box at the film outlet 601, the film hanger 200 near the film outlet 601 moves with the hanger chain to the film inlet 600, where the film is re-hung, and the drying and cooling operation of the next batch of film begins. Compared with the existing technology where the cooling fan unit 100 has a long period of ineffective working time between the completion of the previous batch of film processing and the start of the next batch of film processing, this arrangement can avoid the ineffective working of the cooling fan unit 100, save production costs, and improve the automation level of the glue cooling line air box.

[0050] The advantages of this invention are:

[0051] (1) It can improve the automation level of the glue cooling line air box;

[0052] (2) It can save energy in production;

[0053] (3) Highly practical.
