Description

Technical Field

[0001] This application relates to the processing of cable insulation masterbatch, specifically a feeding device for cable insulation masterbatch. Background Technology

[0002] The insulation layer of a cable is a layer of material located outside the cable conductor. It is used to provide insulation performance for the cable and can prevent short circuits or leakage when current comes into contact with the conductor or the outside environment. The cable insulation layer requires an extruder, whose main function is to coat the cable conductor with the insulation material by extrusion to form the cable insulation layer. The extruder needs a feeding device to continuously and automatically feed the insulation material into the extruder for extrusion.

[0003] Currently, the addition of masterbatch requires manual processing, and only a fixed amount can be added at a time. Although the fixed amount added can be considered as processing requirements, some masterbatch is stored in equipment or materials with a fixed capacity. When this capacity exceeds the capacity we add at one time, the excess masterbatch will overflow from the device, causing waste or long-term exposure to the environment. Utility Model Content

[0004] In view of the above-mentioned related technologies, the purpose of this application is to provide a feeding device for cable insulation masterbatch, which solves the problem that it is difficult to meet the needs of processing and production by adding only a fixed amount of masterbatch each time, and reduces the waste of masterbatch.

[0005] This application provides a feeding device for cable insulation masterbatch, employing the following technical solution: It includes an extruder body, a feeding structure, a screening structure, a storage structure, and a baffle structure. An installation plate is fixedly connected to the upper end of the extruder body, and a conical cylinder is also fixedly connected to the upper end of the extruder body. Two infrared sensors on the same horizontal plane are fixedly connected to the upper end of the conical cylinder. The feeding structure includes two first fixed rods, both of which are fixedly connected to the upper end of the installation plate. A crossbar is rotatably connected to the opposite sides of each of the two first fixed rods, with one crossbar penetrating through a first fixed rod. The two crossbars are connected together. A tilting bucket is fixedly connected to the outside of the tilting bucket. A first base is fixedly connected to one side of the first base. A first motor is fixedly connected to one side of the first base. The output shaft of the first motor is fixedly connected to a rotating rod via a coupling. A bearing seat is fixedly connected to the outside of the rotating rod. The end of the rotating rod away from the first motor is sleeved with a bearing in the middle of the bearing seat. The tilting bucket corresponds to a conical cylinder. A cover plate consistent with the tilting bucket is fixedly connected to the outer wall of the rotating rod. A second base is fixedly connected to one side of the first fixed rod. A second motor is fixedly connected to the upper end of the second base. The output shaft of the second motor is fixedly connected to a crossbar near the bearing seat via a coupling. By adopting the above technical solution, through the setting of a conical cylinder, infrared sensors, a tilting drum, a first motor, a cover plate, and a second motor, the second motor can drive the tilting drum to tilt during use, while simultaneously coordinating with the first motor. Then, the opening and closing of the cover plate can be controlled as needed. As the tilting drum tilts, the masterbatch enters the conical cylinder. When the amount of masterbatch added covers both infrared sensor sensing areas, the infrared sensors, through linkage with the PLC controller, cause the PLC controller to control the first motor to operate, thereby closing the cover plate. Compared to adding only a fixed amount of masterbatch at a time, this device can control the amount added as needed, and promptly stop adding material when the extruder is full, thus avoiding excessive masterbatch overflow and waste, thereby meeting processing requirements.

[0006] Preferably, the screening structure includes two second fixing rods, both of which are fixedly connected to the upper end of the mounting plate.

[0007] Preferably, the upper ends of the two second fixing rods are fixedly connected to a screen box, and two guide plates are fixedly connected to one side of the screen box. Screen plates are snapped into the inside of the screen box by connecting pins.

[0008] Preferably, the screen box has an inclined ramp fixedly connected inside, and an agitator is fixedly connected to the side of the screen box away from the guide plate by a fixing block. The lower end of the screen box is slidably connected to a collection box by a T-shaped groove, and the collection box is placed below the lowest point of the ramp.

[0009] By adopting the above technical solution, the agitator is turned on, causing the agitator to sift the screen box and screen plates, causing the debris or dirt in the masterbatch to fall into the collection box. The debris or dirt separated by the sun slides down the slope platform and into the collection box, thereby achieving collection.

[0010] Preferably, the storage structure includes a storage box, which is fixedly connected to the upper end of the screen box. A discharge port is connected to one side of the storage box, and a first electric telescopic rod is fixedly connected to the upper end of the storage box.

[0011] By adopting the above technical solution, sufficient masterbatch for processing is placed into the storage box through the discharge port to store the masterbatch raw materials.

[0012] Preferably, the output shaft of the first electric telescopic rod is fixedly connected to a baffle, which corresponds to the discharge port of the storage box.

[0013] By adopting the above technical solution, the first electric telescopic rod is then activated, which drives the baffle to move, thereby opening the discharge port of the storage box to add masterbatch to the screen box.

[0014] Preferably, the baffle structure includes a third fixing rod, the upper end of which is fixedly connected to the bottom end of the storage box, and a second electric telescopic rod is fixedly connected to one side of the third fixing rod. The output shaft of the second electric telescopic rod is fixedly connected to a guide shell.

[0015] By adopting the above technical solution, the second electric telescopic rod is activated to drive the guide shell to move, wherein the slot and the guide plate are separated, so that the screened masterbatch falls into the space between the guide plates with vibration.

[0016] Preferably, the guide shell has two slots on one side, and both slots are adapted to the guide plate (303).

[0017] In summary, this application includes at least one of the following beneficial technical effects: This cable insulation masterbatch feeding device, comprising a conical cylinder, infrared sensors, a tilting drum, a first motor, a cover plate, and a second motor, allows the second motor to drive the tilting drum to tilt during operation, simultaneously coordinating with the first motor. The opening and closing of the cover plate is controlled as needed. As the tilting drum tilts, the masterbatch enters the conical cylinder. When the amount of masterbatch added covers both infrared sensor areas, the infrared sensors, in conjunction with a PLC controller, control the first motor to close the cover plate. Compared to devices that can only add a fixed amount of masterbatch at a time, this device allows for real-time control of the amount added and timely stopping feeding once the extruder is full. This prevents excessive masterbatch from overflowing and causing waste, thus adapting to processing requirements.

[0018] This cable insulation masterbatch feeding device, through the arrangement of a screen box, screen plates, ramp, agitator, and collection box, allows the screen plates to be placed into the screen box during use. A pin is used to engage the screen plates and the screen box. When enough masterbatch is available in the screen box, the first electric telescopic rod drives the baffle back to its original position. This activates the agitator, causing it to vibrate the screen box and screen plates, thereby separating debris or dirt from the masterbatch. The separated debris or dirt slides down the ramp into the collection box, thus achieving the purpose of collecting the debris and dirt. Attached Figure Description

A screen box 302 is fixedly connected to the upper ends of both second fixing rods 301. Two guide plates 303 are fixedly connected to one side of the screen box 302. Screen plates 304 are snapped into place inside the screen box 302 via connecting pins. An inclined ramp 305 is fixedly connected inside the screen box 302. An agitator 306 is fixedly connected to the side of the screen box 302 away from the guide plates 303 via a fixing block. The lower end of the box 302 is slidably connected to a collection box 307 via a T-shaped groove. The collection box 307 is positioned below the lowest point of the ramp 305. The storage structure 4 includes a storage box 401, which is fixedly connected to the upper end of the screen box 302. A discharge port 402 is connected to one side of the storage box 401.

A second electric telescopic rod 502 is fixedly connected to one side of the third fixing rod 501. The output shaft of the second electric telescopic rod 502 is fixedly connected to a guide shell 503. Two slots 504 are opened on one side of the guide shell 503, both of which are adapted to the guide plate 303. Through the arrangement of the screen box 302, screen plate 304, ramp 305, agitator 306, and collection box 307, the screen plate can be... 304 is placed into the screen box 302, and the screen plate 304 and the screen box 302 are engaged by using a pin. Then, when there is enough masterbatch in the screen box 302, the first electric telescopic rod 403 drives the baffle to return to its original position. At this time, the agitator 306 is activated in conjunction, causing the agitator 306 to vibrate the screen box 302 and the screen plate 304, thereby separating the debris or dirt mixed in with the masterbatch. The separated debris or dirt slides down the slope 305 into the collection box 307, thereby achieving the purpose of collecting the debris and dirt.

[0024] The implementation principle of this application embodiment is as follows: First, sufficient masterbatch for processing is placed into the storage box 401 through the discharge port 402. Then, the first electric telescopic rod 403 is activated, causing the first electric telescopic rod 403 to drive the baffle 404 to move, thereby opening the discharge port of the storage box 401 to add masterbatch to the screen box 302. After that, the screen plate 304 is placed into the screen box 302, and the screen plate 304 and the screen box 302 are engaged by using a pin. Then, when there is enough masterbatch in the screen box 302, the first electric telescopic rod 403 is activated. Rod 403 drives baffle 404 back to its original position. At this time, the agitator 306 is activated, causing the agitator 306 to vibrate the screen box 302 and screen plate 304, thereby separating debris or dirt mixed in with the masterbatch. The separated debris or dirt slides down the ramp 305 into the collection box 307 for collection. Simultaneously, the second electric telescopic rod 502 is activated, driving the guide shell 503 to move. The slot 504 and the guide plate 303 separate, allowing the screened masterbatch to fall between the guide plates 303 with the vibration. Simultaneously, the first motor 205 is activated, driving the rotating rod 206 to rotate, thereby opening the cover 207. The masterbatch then falls from between the guide plates 303 into the upper tilting drum 203. After a batch of screened masterbatch has entered the tilting drum 203, the first motor 205 reverses to close the cover 207. Then, the second motor 210 is activated, driving the crossbar 202 to rotate, causing the tilting drum 203 to tilt. Simultaneously, the first motor 205 is activated again. Then, the cover plate 207 is opened and closed as needed. As the masterbatch in the pouring bucket 203 enters the conical cylinder 7, when the amount of masterbatch put in covers the sensing areas of both infrared sensors 8, the infrared sensors are linked to the PLC controller, which in turn controls the first motor 205 to run, thereby closing the cover plate 207. This controls the amount of material put into the conical cylinder 7, preventing excessive masterbatch from overflowing and causing waste. After that, the extruder body 1 is turned on to realize the subsequent processing and extrusion of the masterbatch.
