Description

Technical Field

[0001] The utility model relates to the technical field of polyvinyl chloride insulated cable coating and feeding, in particular to a polyvinyl chloride insulated cable coating and feeding device. Background Art

[0002] In the production of PVC insulated cables, the efficiency and accuracy of the loading process have a crucial impact on the production capacity and product quality of the entire production line. Traditional cable material loading methods rely heavily on manual operations, which have many drawbacks.

[0003] In the early days, operators had to manually carry cable material packaging bags to designated locations, then use cutters to cut the bags one by one, and then pour the cable material into the loading equipment or directly transport it to the coating process. This manual cutting and carrying method is extremely labor-intensive, not only consuming a lot of manpower and time, but also because manual operation makes it difficult to ensure the consistency of the position and depth of each cut, it is easy to cause the cable material to spill and be wasted, and it may also be mixed with impurities, affecting the insulation performance and quality stability of the cable.

[0004] With the development of industrial automation technology, some simple feeding devices have begun to emerge. However, these devices often have limited functions, such as simple material conveying and lacking effective handling mechanisms for cable material bags. Regarding material collection, they often lack specially designed collection chambers and ventilation systems. Material easily accumulates in the conveying channel, causing blockages, affecting feeding continuity, and thus reducing production efficiency. Furthermore, debris generated during the cutting process cannot be cleaned promptly, easily contaminating the work environment and posing a health risk to operators. It may also adhere to the cable material, affecting product quality. To address these issues, we have developed a feeding device for PVC-insulated cable sheathing. Utility Model Content

[0015] (3) Beneficial effects:

[0016] Compared with the existing technology, the PVC insulated cable coating feeding device has the following beneficial effects:

[0017] 1. The utility model can accurately cut the bottom of the cable material packaging bag by the forward and backward movement of the cutter head in conjunction with the threaded barrel. Since the cutter head is higher than the receiving plate and the curvature of the receiving plate is adapted to the cable material packaging bag, the cutter head can stably and accurately cut the packaging bag during the movement of the threaded barrel, so that the cable material falls smoothly into the collection chamber below.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] like Figure 1-6 As shown, the utility model provides a technical solution: a polyvinyl chloride insulated cable coating feeding device, including a storage shell 1, a placement shell 2 fixed above the storage shell 1, the front and rear ends of the storage shell 1 are inlaid with bearings 13, a rotating shaft 14 is provided in the bearing 13, a threaded rod 15 is fixed between the opposite surfaces of the rotating shaft 14, and a threaded cylinder 16 is threadedly connected to the surface of the threaded rod 15. In order to ensure the linearity and stability of the threaded cylinder 16 during the forward and backward movement, a limiting groove 19 is symmetrically opened inside the storage shell 1, and a sliding limiting block 17 matching it is installed in the limiting groove 19 to ensure the limit The positioning block 17 slides freely in the limiting groove 19 and can effectively prevent it from shaking or deflecting, so that the threaded barrel 16 always moves in the direction defined by the limiting groove 19 during the movement, avoiding the deviation from the track due to uneven force or other factors, greatly improving the accuracy and reliability of the cutting action. The rotating shaft 14 at the front end of the storage shell 1 is fixedly connected to the output shaft of the motor 7. When the motor 7 receives the start signal, its output shaft starts to rotate and transmits power to the rotating shaft 14, thereby driving the entire transmission system to start working, realizing the back and forth movement of the threaded barrel 16 and the cutting action of the cutter head 20.

[0028] Specifically, such as Figure 4 As shown, the placement shell 2 is symmetrically provided with a receiving plate 12 with an arc surface, and the cable material packaging bags 3 are gradually placed inside the placement shell 2 and on the surface of the receiving plate 12. The receiving plates 12 with an arc surface are symmetrically provided inside the placement shell 2 to reduce the friction between the cable material packaging bags 3 and the receiving plate 12. A plurality of cable material packaging bags 3 can be gradually placed inside the placement shell 2 and on the surface of the receiving plate 12. These cable material packaging bags 3 can maintain a stable placement state under the support of the receiving plate 12 and will not easily roll or slide. Moreover, since the height of the cutter head 20 is higher than the height of the receiving plate 12, when the threaded cylinder 16 moves forward under the drive of the motor 7, the cutter head 20 can smoothly contact the bottom of the cable material packaging bag 3 and cut it, so that the cable material can fall into the collection chamber 22 through the through hole 21 at the bottom end of the storage shell 1, thereby realizing the initial loading process of the material and reducing the process of personnel carrying the material to a high place.

[0029] Specifically, such as Figure 3As shown, a cutter head 20 is fixed to the upper surface of the threaded barrel 16, and the height of the cutter head 20 is higher than the height of the receiving plate 12. When the rotating shaft 14 rotates under the drive of the motor 7, the threaded rod 15 can rotate synchronously, thereby driving the threaded barrel 16 threadedly connected thereto to perform linear reciprocating motion. Under the rotation of the threaded rod 15, it can move smoothly back and forth along the axial direction of the storage shell 1. At the same time, a cutter head 20 for cutting the cable material packaging bag 3 is provided on the upper surface of the threaded barrel 16. The shape of the cutter head 20 is designed to be a slightly curved long strip, so as to better adapt to the curved shape of the bottom of the cable material packaging bag 3, ensuring that the bottom of the packaging bag can be quickly and neatly cut during the cutting process, so that the cable material therein can fall smoothly.

[0030] Specifically, such as Figure 5 As shown, a through hole 21 is provided at the bottom of the storage shell 1, and a collecting chamber 22 is provided inside the bottom of the storage shell 1 below the through hole 21, and a fan 6 provided at the front end of the storage shell 1 is connected to the inside of the collecting chamber 22 through a pipeline. The use of the fan 6 can generate a strong airflow, and the airflow enters the collecting chamber 22 through the pipeline. On the one hand, when the cutter head 20 cuts the cable material packaging bag 3, the airflow generated by the fan 6 can quickly suck the impurities such as debris, dust and small fragments of the packaging bag generated during cutting into the collecting chamber 22, preventing these impurities from floating in the working environment and keeping The cleanliness of the working area is maintained to avoid adverse effects on the subsequent cable coating process; on the other hand, the air flow forms a certain disturbance in the collecting chamber 22, which can make the falling cable material more loosely distributed at the bottom of the collecting chamber 22, preventing it from clogging the through hole 21 or affecting the normal operation of the suction pump 11 due to excessive accumulation, and an air outlet duct 8 is provided at the rear end of the storage shell 1, and the air outlet duct 8 is connected to the collection chamber 22 in the storage shell 1. At the same time, with the help of the wind force of the fan 6, the dust in the collection chamber 22 is sent to the external collection bag through the air outlet duct 8 for collection.

[0031] Specifically, such as Figure 2 As shown, a support plate 9 is fixed above the rear end of the storage shell 1, and a suction pump 11 is fixed on the support plate 9. The suction pump 11 is connected to the interior of the storage shell 1 through a suction pipe 10, and the suction pipe 10 is located above the through hole 21. The suction pump 11 and the suction pipe 10 are used to suck and load the cable material in the storage shell 1, thereby reducing manual handling and loading.

[0032] Specifically, such as Figure 6As shown, a contact switch 18 is provided on the front and rear inner walls of the limit groove 19, a fixed plate 4 is provided at the front end of the storage shell 1, a signal light 5 is fixed on the surface of the fixed plate 4, and the motor 7 and the fan 6 are fixed on the surface of the fixed plate 4, the contact switch 18, the signal light 5, the fan 6, the motor 7 and the suction pump 11 are electrically connected to the controller 23 through wires. When the limit block 17 triggers the contact switch 18, the signal light 5 will flash, and the personnel need to remove the cable material packaging bag 3 after cutting, and at the same time, the motor 7 reverses to move the cutter head 20 to the front end of the storage shell 1, and replace it with a new cable material packaging bag 3 with cable material, and the entire working fan 6 and suction pump 11 continue to load the material.
