Description

Technical Field

[0001] The utility model relates to the technical field of cable production, in particular to a preheating device for electric wire and cable production. Background Art

[0002] The wire and cable preheating device is a device that inserts the wire and cable into the preheating device and pulls it out from the other end. The time period of entry is the preheating stage of the preheating device. Its appearance can remove moisture from the surface of the wire and cable, so that the quality of the wire and cable is guaranteed for future engineering use.

[0003] After searching, it is found that a preheating device for the production of wires and cables is disclosed in Chinese patent documents [Application number: CN202022948111.9]. This preheating device for the production of wires and cables includes a preheating device body, a disc rack is installed on the outer surfaces of both sides of the preheating device body, a door panel is installed on the outer surface of the front end of the preheating device body, a connecting rod is connected to the inner wall of the preheating device body, and a cylinder is connected to the outer surface of the connecting rod. A hot air blower and a hair dryer are installed on the inner walls of both ends of the preheating device body, respectively. The hot air blower is located at the upper end of the hair dryer, and a take-up reel is installed on the outer surface of the upper end of the preheating device body. The outer surfaces of both sides of the preheating device body are provided with wire inlets.

[0004] The device disclosed in the patent can preheat the cable when in use, but the surface of the cable will be contaminated with dust and foreign matter during the actual production process, and the device cannot clean the foreign matter when in use, so that when moving during the preheating process, the foreign matter will be contaminated inside the device, which will contaminate other cables, thereby affecting the subsequent use of the cable;

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-5As shown, a preheating device for producing electric wires and cables comprises a preheating device body 1. The preheating device body 1 can preheat the surface of the cable through an internal heater to reduce moisture on the cable surface. One side of the preheating device body 1 is connected to a mounting shell 2. The mounting shell 2 is connected to the interior of the preheating device body 1, so that the cable enters the interior of the mounting shell 2 before entering the preheating device body 1. A stepper motor 3 is bolted to the top of the mounting shell 2. The output shaft of the stepper motor 3 is fixedly connected to a connecting shaft 4. A spur gear 5 is fixedly sleeved on one side of the surface of the connecting shaft 4. The inner cavity of the mounting shell 2 is provided with a spur gear 5. One side is rotatably connected with a gear ring 6, and the surface of the spur gear 5 penetrates into the interior of the mounting shell 2 and meshes with the gear ring 6, so that the spur gear 5 can drive the gear ring 6 to rotate when it rotates. The interior of the gear ring 6 is fixedly connected with a connecting rod 7. The number of connecting rods 7 is several, and they are all distributed in a ring array at the center of the gear ring 6. One end of the connecting rod 7 is fixedly connected with a scraper 8, and the scraper 8 is made of rubber. The scraper 8 and the number correspond to the connecting rod 7. Under this action, the scraper 8 can scrape the surface of the cable, so as to reduce foreign matter on the cable surface, and under the effect of material and number, It can also improve the cleaning effect of the cable, effectively making the cable cleaner. A bevel gear set 9 is installed at one end of the connecting shaft 4 away from the stepper motor 3. The bevel gear set 9 is composed of two bevel gears of the same volume meshing with each other. Under this action, the rotation of the connecting shaft 4 can be transmitted. A blade 10 is installed on the top of the bevel gear set 9. Under this action, the bevel gear set 9 can transmit the power of the rotation of the connecting shaft 4 to the surface of the blade 10, so that the blade 10 can rotate. At this time, the blade 10 accelerates the cavity. A cleaning mechanism 11 is provided on the surface of the mounting shell 2. The cleaning mechanism 1 1 can be used in conjunction with the blades 10 to blow the accelerated air to the surface of the cable, so that the surface of the cable can be cleaner, and the larger water on the surface of the cable can be blown away, so as to facilitate the subsequent preheating of the cable by the preheating device body 1. The inner cavity of the installation shell 2 is fixedly connected with a connecting plate 12, and the interior of the installation shell 2 can be divided under the action of the connecting plate 12. One side of the connecting plate 12 is fixedly connected with a water absorption plate 13, and the water absorption plate 13 is designed as a water absorption sponge. Under this action, the water blown out by the cleaning mechanism 11 can be absorbed, so as to prevent the blown water from being splashed around by the air.

[0025] The cleaning mechanism 11 includes a fixed shell 111, one side of which is fixedly connected to the surface of the mounting shell 2, the blade 10 is located inside the fixed shell 111, and the inner wall of the fixed shell 111 is rotatably connected to the surface of the connecting shaft 4, thereby supporting the connecting shaft 4 so that it can be more stable when rotating. The bottom of the fixed shell 111 is connected to a connecting pipe 112, and the number of the connecting pipes 112 is two, and both penetrate into the interior of the mounting shell 2. The other end of the connecting pipe 112 is connected to an air outlet shell 113. Under this action, the fixed shell 111 and the connecting pipe 112 can guide the air accelerated by the blade 10, so that it can The water and foreign matter on the surface of the cable are cleaned by discharging the water through the air outlet shell 113. The air outlet shell 113 is designed as an inclined structure. The air outlet of the air outlet shell 113 is close to one side of the water absorption plate 13. Under this action, the water can be blown to the surface of the water absorption plate 13, thereby facilitating the collection of water. A protective frame 14 is bolted above the inner cavity of the fixed shell 111. The top of the protective frame 14 is in the same horizontal plane as the top of the fixed shell 111. Under this action, the blade 10 can be blocked to prevent foreign matter from entering the interior of the fixed shell 111 when the blade 10 rotates and causing damage to the blade 10, thereby effectively improving the service life of the blade 10.

[0026] It is worth noting that the preheating device body 1 proposed in this technical solution is the technology in the comparative case. The specific structure, working principle, and possible control method and spatial layout method of these technical features can all be adopted from the comparative case, and this technical solution will not be further elaborated.

[0027] Working principle: first, the cable is passed through the interior of the mounting shell 2 and then wound around the interior of the preheating device body 1 in sequence. Then, the heater inside the preheating device body 1 is turned on to preheat the surface of the cable. At the same time, the stepper motor 3 is turned on. Under the action of the stepper motor 3, the spur gear 5 is driven by the connecting shaft 4 to make the gear ring 6 drive the connecting rod 7 to rotate, so that the scraper 8 scrapes the surface of the cable, thereby cleaning the foreign matter on the surface of the cable to prevent larger foreign matter from affecting the subsequent cable production. Then, under the action of the connecting shaft 4, the blade 10 is driven by the bevel gear set 9 to accelerate the air. Then, the accelerated air enters the interior of the fixed shell 111 and is discharged from the air outlet shell 113 through the connecting pipe 112, so as to clean the foreign matter and water on the surface of the cable, thereby facilitating the preheating of the cable by the preheating device body 1. The cleaned cable enters the interior of the preheating device body 1 for preheating.
