Description

Technical Field

[0001] This utility model belongs to the field of cable shielding material processing technology, specifically relating to a cable shielding material drying equipment with a layered air supply mechanism. Background Technology

[0002] Cable shielding material is a functional material used to wrap conductors or insulation layers. If the cable shielding material is exposed to rain or high humidity during storage, it will absorb a large amount of moisture. In order to prevent the moisture from affecting the material's performance, it needs to be dried.

[0003] Existing drying equipment supplies air into the chamber through air inlets. Cable shielding materials are either piled up together or placed in layers. However, the airflow is difficult to evenly cover the surface of the cable shielding materials. When the cable shielding materials are piled up together, the airflow is not smooth due to the small and irregular gaps between the materials, resulting in some materials not being able to fully contact the drying airflow. Even when the cable shielding materials are placed in layers, although the contact area between the airflow and the materials is increased to some extent, the air supply method of the air inlets is relatively fixed. When the airflow reaches different layers of materials, the airflow will vary depending on the distance from the air inlet and the natural flow characteristics of the airflow in the chamber, resulting in differences in the airflow received by the surface of each layer of materials. Utility Model Content

[0004] The purpose of this invention is to provide a cable shielding material drying device with a layered air supply mechanism, so as to solve the problem that the existing drying equipment has a single air supply method, which is not convenient for the cable shielding material to dry evenly.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A cable shielding material drying device with a layered air supply mechanism includes a drying chamber and a hot air blower. A duct is provided between the drying chamber and the hot air blower, and the two ends of the duct are respectively connected to the drying chamber and the hot air blower. An auxiliary mechanism is provided inside the drying chamber. The auxiliary mechanism includes a first limiting plate and a second limiting plate fixedly connected inside the drying chamber. The second limiting plate is located below the first limiting plate. Three filters are provided inside the drying chamber.

[0007] Preferably, the drying chamber is provided with two connecting rods inside, and three rectangular plates are fixedly connected to the arc surfaces of the two connecting rods. The six rectangular plates are arranged in pairs, and the rectangular plates in the same group are fixedly connected to both ends of the filter screen.

[0008] Preferably, a fixing plate is fixedly connected to the inner wall of the drying chamber, and a rotating rod is rotatably connected to the surface of the fixing plate. A blade and a gear are fixedly connected to both ends of the rotating rod, respectively. A rack is meshed with the tooth surface of the gear. The rack is fixedly connected to the surface of one of the rectangular plates. A sliding rod is fixedly connected to both ends of the rectangular plate. A cylinder is slidably connected to the arc surface of the sliding rod. The cylinder is fixedly connected to the inner wall of the drying chamber.

[0009] Preferably, the arc surface of the slide rod is fitted with a spring, and the two ends of the spring are fixedly connected to the cylinder and the rectangular plate, respectively.

[0010] Preferably, the drying chamber has two doors on its front, and the conduit is a flexible hose.

[0011] Preferably, the cross-sectional shape of the second limiting plate is triangular.

[0012] Preferably, the number of teeth on the gear tooth surface is incomplete.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model guides the airflow direction through the limiting plates of the first and second limiting plates, thereby stratifying the airflow and ensuring that it flows in layers according to design requirements, accurately directing it to different layers of cable shielding material. Compared to unguided natural airflow, this greatly improves the controllability of the airflow, ensuring that each layer of cable shielding material receives a relatively uniform and stable airflow, effectively avoiding airflow turbulence and uneven distribution.

[0015] 2. This utility model utilizes airflow to blow on the blades, enabling gear and rack transmission to achieve the effect of shaking the filter screen. The shaking of the filter screen causes the cable shielding material on the filter screen to shake. Through the shaking of the filter screen, the cable shielding material continuously changes its position and orientation, and the surface of the cable shielding material that was originally difficult for the airflow to reach is fully exposed. This greatly increases the contact area between the cable shielding material and the airflow, allowing the drying airflow to act more evenly on all parts of the cable shielding material, effectively avoiding uneven drying in certain areas and improving the drying quality.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figures 1-5 As shown, this utility model provides a cable shielding material drying device with a layered air supply mechanism, including a drying chamber 1 and a hot air blower 2. A conduit 201 is provided between the drying chamber 1 and the hot air blower 2. The two ends of the conduit 201 are respectively connected to the drying chamber 1 and the hot air blower 2. Two chamber doors 101 are installed on the front of the drying chamber 1. The conduit 201 is a flexible hose. An auxiliary mechanism 3 is provided inside the drying chamber 1. The auxiliary mechanism 3 includes a first limiting plate 301 and a second limiting plate 302 fixedly connected inside the drying chamber 1. The second limiting plate 302 is located below the first limiting plate 301. Three filters 304 are provided inside the drying chamber 1.

[0024] In this embodiment, the cross-sectional shape of the second limiting plate 302 is triangular. After the airflow comes into contact with the second limiting plate 302, the airflow will be guided by the hypotenuse of the second limiting plate 302, causing the airflow to flow in two directions.

[0025] In an optional embodiment: the interior of the drying chamber 1 is provided with two connecting rods 305, and three rectangular plates 303 are fixedly connected to the arc surfaces of the two connecting rods 305. The six rectangular plates 303 are arranged in pairs, and the rectangular plates 303 in the same group are fixedly connected to both ends of the filter screen 304.

[0026] It should be noted that the connecting rod 305 serves to secure the three filter screens 304 together.

[0027] In an optional embodiment: a fixing plate 306 is fixedly connected to the inner wall of the drying chamber 1, a rotating rod 307 is rotatably connected to the surface of the fixing plate 306, a blade 308 and a gear 309 are fixedly connected to both ends of the rotating rod 307 respectively, a rack 310 is meshed with the tooth surface of the gear 309, the rack 310 is fixedly connected to the surface of one of the rectangular plates 303, a sliding rod 312 is fixedly connected to both ends of the rectangular plate 303, a cylinder 313 is slidably connected to the arc surface of the sliding rod 312, and the cylinder 313 is fixedly connected to the inner wall of the drying chamber 1.

[0028] In an optional embodiment: a spring 311 is fitted onto the arc surface of the slide bar 312, and the two ends of the spring 311 are fixedly connected to the cylinder 313 and the rectangular plate 303, respectively.

[0029] It should be noted that the number of teeth on the tooth surface of gear 309 is incomplete, and under the elastic force of spring 311, rack 310 can drive filter screen 304 to move back and forth. Through the shaking of filter screen 304, cable shielding material continuously changes position and posture, and the surface of cable shielding material that was originally difficult for airflow to reach is fully exposed, greatly increasing the contact area between cable shielding material and airflow.

[0030] The working principle of this utility model is as follows: During use, the operator places the cable shielding material on multiple filters 304. Hot air is then introduced into the drying chamber 1 by starting the hot air blower 2 to dry the cable shielding material inside the chamber 1. When the airflow enters the drying chamber 1, it is guided by the first limiting plate 301 and the second limiting plate 302, causing the airflow to flow in three directions. This directional airflow dries the cable shielding material on the three filters 304, achieving a layered air delivery effect. When blown, the blades 308 rotate, driving the gear 309 to rotate. The gear 309 transmits power to the rack 310, causing the filter screen 304 to move. At this time, the spring 311 deforms. Since the number of teeth on the gear 309 is incomplete, when the gear 309 is not in contact with the rack 310, the spring 311 rebounds, causing the filter screen 304 to rebound. This achieves the effect of repeatedly shaking the filter screen 304, which facilitates the shaking of the cable shielding material on the filter screen 304, increases the contact area between the cable shielding material and the hot airflow, and improves the drying effect.

[0031] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
