Description
Technical Field
[0001] This utility model relates to the field of wire and cable technology, specifically to a preheated wire and cable chipper. Background Technology
[0002] In the process of recycling or processing wires and cables, it is often necessary to chip them. Preheating and softening the wires and cables before chipping can effectively improve chipping efficiency and results.
[0003] According to a publicly disclosed wire and cable chipper (publication number: CN222365422U), it includes: a base, a support plate fixedly installed on the top of the base, support legs fixedly installed below the base, a conveying assembly on the support plate, a chipping mechanism on the support plate, and a preheating assembly on the support plate, the preheating assembly including a servo motor, and the servo motor fixedly installed on the surface of the support plate. This wire and cable chipper, in order to achieve better chipping of wires and cables, incorporates a preheating assembly, a servo motor, a conveying rod, a vertical plate, a movable plate, a cylinder, a fixed column, a guide block, a connecting rod, a fixed block, a support rod, and a heating machine. When the servo motor is activated, the support rod drives the heating machine to move, thereby preheating and softening the wires and cables before chipping them, making wire and cable chipping more convenient.
[0004] The structure in the above application, which uses a servo motor to drive the heating machine, achieves the preheating and softening of wires and cables to facilitate chipping. However, it suffers from uneven heating and low heat utilization during the preheating process. Therefore, we propose a preheating wire and cable chipper. Utility Model Content
[0005] To overcome the above-mentioned defects, this utility model provides a preheating wire and cable chipper, which solves the problems of uneven preheating of wires and cables, low heat utilization rate, and the equipment's operational stability being affected by dust in the prior art.
[0006] According to one aspect, at least one embodiment of the present invention provides a preheating wire and cable chipper, comprising: a machine base, a cutting box fixedly connected to the top of the machine base, a discharge pipe fixedly connected to the side of the cutting box, a heating box fixedly connected to one end of the discharge pipe, a feeding pipe fixedly connected to the side of the heating box, and a hot air device provided on the side of the heating box. The air-heating device includes a heat pipe, which is fixedly connected to the inner wall of the heating box. An air inlet slot is provided on the side of the heating box near the heat pipe. A fixed frame is fixedly connected to the side of the heating box near the air inlet slot. A rotating shaft is fixedly connected to the side of the fixed frame. A driving impeller shaft is rotatably connected to the side of the rotating shaft. A driven impeller shaft is rotatably connected to the side of the rotating shaft. A driving pulley is fixedly connected to the circumferential surface of the driving impeller shaft. A driven pulley is fixedly connected to the circumferential surface of the driven impeller shaft. A belt is provided on the circumferential surface of the driving pulley. A motor is fixedly connected to one end of the driving impeller shaft.
[0007] For example, in at least one embodiment of the present invention, a preheating wire and cable chipper is provided, which further includes: the preheating wire and cable chipper is characterized in that a bracket is fixedly connected to the circumferential surface of the motor, the bottom of the bracket is fixedly connected to the top of the machine base, the bracket fixes the motor on the machine base, provides stable support for the motor, avoids displacement or shaking of the motor due to vibration during operation, and ensures stable operation of transmission components such as the active impeller shaft.
[0008] The number of driven impeller shafts and driven pulleys is two. The driven impeller shafts and driven pulleys are symmetrical to each other along the vertical central axis of the fixed frame. The two driven impeller shafts and driven pulleys, which are symmetrical along the vertical central axis of the fixed frame, can cooperate with the driving impeller shaft to form a balanced airflow input, so that the air distribution entering the heating box is more uniform.
[0009] The driving pulley is connected to the driven pulley via a belt. The diameter of the driving pulley is larger than that of the driven pulley. The driving pulley drives the driven pulley to rotate via the belt, which realizes stable power transmission and ensures that the driven impeller shaft can rotate synchronously with the driving impeller shaft. The fixed frame is fixedly connected to the side with a reinforcing plate. The number of reinforcing plates is set to a certain number. The reinforcing plates can enhance the structural strength and rigidity of the fixed frame, prevent the fixed frame from deforming under the force generated by the impeller shaft, and ensure the installation stability of components such as the rotating shaft and impeller shaft.
[0010] According to another aspect, at least one embodiment of the present invention also provides a preheating wire and cable chipper, comprising: a return device, the return device including an air collection box, the side of the air collection box being fixedly connected to the side of a heating box, an air outlet being provided on the side of the heating box, a return air pipe being fixedly connected to the top of the heating box, one end of the return air pipe being fixedly connected to the top of the air collection box, a protective box being fixedly connected to the side of the fixed frame, a filter screen being fixedly connected to the side of the protective box, and a cleaning disc being fixedly connected to the circumferential surface of the motor output end.
[0011] For example, in at least one embodiment of the present invention, a preheating wire and cable chipper is provided, which further includes: a cleaning brush fixedly connected to the side of the cleaning disc, the side of the cleaning brush contacting the side of the filter screen, and the cleaning brush contacting the side of the filter screen. When the motor drives the cleaning disc to rotate, the cleaning brush can clean the surface of the filter screen, remove dust, impurities, etc. attached to the filter screen in time, and avoid the filter screen from being blocked and affecting the air intake effect.
[0012] The cleaning brushes are configured in pairs and are symmetrical about each other along the vertical central axis of the motor. The diameter of each cleaning brush is equal to the radius of the filter screen. The two cleaning brushes, which are symmetrical about the vertical central axis of the motor, can clean the filter screen from different positions, increasing the cleaning coverage and improving the cleaning effect.
[0013] An auxiliary heat pipe is provided on the inner wall side of the heating box. The auxiliary heat pipe is fixedly connected to the side of the heating box near the air outlet. The auxiliary heat pipe can reuse part of the heat that is about to flow out of the air outlet and supplement the heating of the wires and cables in the area near the air outlet inside the heating box.
[0014] The number of air outlets is set to several, and the air outlets are arranged in a linear array on the side of the heating box. The number of air outlets arranged in a linear array increases the exchange area between the air inside the heating box and the outside, so that the hot air inside the heating box can be discharged more smoothly and avoid the accumulation of hot air inside the heating box, which would cause the local temperature to be too high.
[0015] The beneficial effects of the embodiments of this utility model are as follows: 1. In this utility model, the air-heating device ensures the stability of equipment operation and preheating efficiency through a reasonable structural design. The bracket firmly fixes the motor to the base of the machine body, preventing the vibration of the motor from affecting the transmission of components such as the active impeller shaft; the reinforcing plate enhances the rigidity of the fixed frame and prevents it from deforming when the impeller shaft is running; the active pulley drives the driven pulley to rotate through the belt, and the combination of the size difference between the two increases the speed of the driven impeller shaft while stably transmitting power, thereby enhancing the air intake force, while the symmetrical driven impeller shaft makes the air intake more uniform, ensuring a stable and efficient preheating process for wires and cables.
[0016] 2. In this utility model, the return flow device achieves efficient utilization of heat and continuous stable operation of the equipment. The return air duct returns some heat to the heating box, and the auxiliary heat pipe supplements the heating of the area near the air outlet, thereby improving the heat utilization rate. The cleaning brush rotates with the motor to clean the filter screen, avoiding filter screen blockage and affecting air intake. The symmetrically arranged cleaning brush can thoroughly clean the filter screen and ensure smooth air intake. Several linear arrays of air outlets allow the airflow in the heating box to circulate stably, further ensuring the preheating effect. Attached Figure Description

[0026] like Figures 1-5 The present invention illustrates a preheating wire and cable chipper in one embodiment of the present invention, comprising: a machine base 1, a cutting box 2 fixedly connected to the top of the machine base 1, a discharge pipe 3 fixedly connected to the side of the cutting box 2, a heating box 4 fixedly connected to one end of the discharge pipe 3, a feeding pipe 5 fixedly connected to the side of the heating box 4, and a hot air device 6 provided on the side of the heating box 4. The air-heating device 6 includes a heat pipe 601, which is fixedly connected to the inner wall side of the heating box 4. An air inlet slot 602 is provided on the side of the heating box 4 near the heat pipe 601. A fixed frame 603 is fixedly connected to the side of the heating box 4 near the air inlet slot 602. A rotating shaft 604 is fixedly connected to the side of the fixed frame 603. A driving impeller shaft 605 is rotatably connected to the side of the rotating shaft 604. A driven impeller shaft 606 is rotatably connected to the side of the rotating shaft 604. A driving pulley 607 is fixedly connected to the circumferential surface of the driving impeller shaft 605. A driven pulley 608 is fixedly connected to the circumferential surface of the driven impeller shaft 606. A belt 609 is provided on the circumferential surface of the driving pulley 607. A motor 610 is fixedly connected to one end of the driving impeller shaft 605.
[0027] In some examples, a bracket 611 is fixedly connected to the circumferential surface of the motor 610. The bottom of the bracket 611 is fixedly connected to the top of the base 1. The bracket 611 fixes the motor 610 to the base 1, providing stable support for the motor 610 and preventing the motor 610 from shifting or shaking due to vibration during operation, thus ensuring the stable operation of transmission components such as the active impeller shaft 605. There are two driven impeller shafts 606 and two driven pulleys 608. The driven impeller shafts 606 and driven pulleys 608 are symmetrical to each other along the vertical central axis of the fixed frame 603. The two driven impeller shafts 606 and driven pulleys 608, which are symmetrical along the vertical central axis of the fixed frame 603, can cooperate with the driving impeller shaft 605 to form a balanced airflow input, so that the air distribution entering the heating box 4 is more uniform. The driving pulley 607 is connected to the driven pulley 608 via a belt 609. The diameter of the driving pulley 607 is larger than that of the driven pulley 608. The driving pulley 607 drives the driven pulley 608 to rotate via the belt 609, thus achieving stable power transmission and ensuring that the driven impeller shaft 606 can rotate synchronously with the driving impeller shaft 605. The fixed frame 603 is fixedly connected to the side with a reinforcing plate. Several reinforcing plates are provided. The reinforcing plates can enhance the structural strength and rigidity of the fixed frame 603, prevent the fixed frame 603 from deforming under the force generated by the impeller shaft, and ensure the installation stability of components such as the rotating shaft 604 and the impeller shaft. According to another aspect, at least one embodiment of the present invention also provides a preheating wire and cable chipper, comprising: a reflux device 7 provided on the side of a heating box 4, the reflux device 7 including an air collection box 701, the side of the air collection box 701 being fixedly connected to the side of the heating box 4, an air outlet 702 being provided on the side of the heating box 4, a return air pipe 703 being fixedly connected to the top of the heating box 4, one end of the return air pipe 703 being fixedly connected to the top of the air collection box 701, a protective box 704 being fixedly connected to the side of a fixed frame 603, a filter screen 705 being fixedly connected to the side of the protective box 704, and a cleaning disc 706 being fixedly connected to the circumferential surface of the output end of a motor 610.
[0028] For example, such as Figures 1-5 After the wires and cables enter the heating chamber 4 through the feed pipe 5, the operator starts the hot air device 6. The motor 610, fixedly supported by the bracket 611, begins operation, driving the active impeller shaft 605 to rotate. The active pulley 607 on the active impeller shaft 605 drives two driven pulleys 608 to rotate via the belt 609, thus causing the driven impeller shaft 606 to rotate synchronously with the active impeller shaft 605. Because the diameter of the active pulley 607 is larger than that of the driven pulleys 608, the driven impeller shaft 606 rotates at a higher speed. The resulting airflow enters the heating chamber 4 through the air inlet slot 602. The heat pipe 601 is energized and heats up, exchanging heat with the airflow entering the heating chamber 4 to form hot air that preheats the wires and cables. The reinforcing plates on the sides of the fixed frame 603 enhance the frame's stability, preventing frame deformation during impeller shaft operation and ensuring stable airflow input. The two symmetrical driven impeller shafts 606 ensure even airflow distribution, resulting in more uniform heating of the wires and cables and providing suitable preheating conditions for subsequent cutting in the cutting box 2.
[0029] like Figures 1-5 This illustration shows a preheating wire and cable chipper according to another embodiment of the present invention, comprising: a return device 7, the return device 7 including an air collection box 701, the side of the air collection box 701 being fixedly connected to the side of the heating box 4, the side of the heating box 4 having an air outlet 702, the top of the heating box 4 being fixedly connected to a return air pipe 703, one end of the return air pipe 703 being fixedly connected to the top of the air collection box 701, the side of the fixed frame 603 being fixedly connected to a protective box 704, the side of the protective box 704 being fixedly connected to a filter screen 705, and a cleaning disc 706 being fixedly connected to the circumferential surface of the output end of the motor 610.
[0030] In some examples, a cleaning brush 707 is fixedly connected to the side of the cleaning disc 706. The side of the cleaning brush 707 is in contact with the side of the filter screen 705. When the motor 610 drives the cleaning disc 706 to rotate, the cleaning brush 707 can clean the surface of the filter screen 705, remove dust, impurities and other debris attached to the filter screen 705 in a timely manner, and prevent the filter screen 705 from becoming clogged and affecting the air intake effect.
[0031] There are two cleaning brushes 707, which are symmetrical to each other along the vertical central axis of the motor 610. The diameter of the cleaning brush 707 is equal to the radius of the filter screen 705. The two cleaning brushes 707, which are symmetrical along the vertical central axis of the motor 610, can clean the filter screen 705 from different positions, increase the cleaning coverage area, and improve the cleaning effect. An auxiliary heat pipe is provided on the inner wall side of the heating box 4. The auxiliary heat pipe is fixedly connected to the side of the heating box 4 near the air outlet 702. The auxiliary heat pipe can reuse part of the heat that is about to flow out of the air outlet 702 and supplement the heating of the wires and cables in the area near the air outlet 702 inside the heating box 4. The number of air outlets 702 is set to several, and the air outlets 702 are arranged in a linear array on the side of the heating box 4. The number of air outlets 702 arranged in a linear array increases the exchange area between the air inside the heating box 4 and the outside, so that the hot air inside the heating box 4 can be discharged more smoothly, and avoids the accumulation of hot air inside the heating box 4, which would cause the local temperature to be too high.
[0032] For example, such as Figures 1-5 While the heating box 4 preheats the wires and cables, the recirculation device 7 operates synchronously. Part of the hot air generated by heating is discharged from the outlets 702 of several linear arrays. The auxiliary heat pipes near the outlets 702 reuse the heat from this portion of the hot air to supplement the heating of nearby wires and cables. The discharged hot air enters the air collection box 701 and then flows back to the heating box 4 through the return air pipe 703, achieving heat recycling. When the motor 610 runs, it drives the cleaning disc 706 to rotate. Two symmetrical cleaning brushes 707 on the cleaning disc 706 rotate with it, cleaning the filter screen 705 on the side of the protective box 704. The diameter of the cleaning brushes 707 is matched to the radius of the filter screen 705, effectively removing dust from the filter screen 705 and preventing clogging that could affect airflow. After being filtered by the filter screen 705, outside air enters the area of the fixed frame 603, providing a stable air source for the impeller shaft and ensuring the coordinated operation of the heating device 6 and the recirculation device 7. It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
