Description

Technical Field

[0001] The invention belongs to the field of iron core manufacturing equipment, and more specifically, relates to an iron core winding device. Background Art

[0002] The core winding machine is a special equipment for winding silicon steel strip cores. It can produce ring-shaped, rectangular and other shaped cores. In order to obtain feasible low hysteresis loss, production must be carried out under special control conditions. Generally, pure iron is not suitable for alternating magnetic fields, mainly because its resistivity is low and will cause large eddy current losses. After adding silicon, the resistivity is increased because silicon and iron form a solid solution alloy. Silicon steel strip uses the increase in resistivity to reduce the eddy current loss caused by the thickness direction. Eddy current loss is proportional to the thickness of the silicon steel strip. Usually, the thickness of the silicon steel strip used for the core is 0.35~0.5mm.

[0003] In the prior art, when the stator core is wound with silicon steel strips, if the winding operation is performed in a hot working environment, the silicon steel strips are continuously wound on the stator core, resulting in increasingly poor air permeability of the silicon steel strips and reduced self-heat dissipation efficiency, which causes the core and the silicon steel strips to expand due to heat, and increases the gap between the silicon steel strips after winding is completed, thereby affecting the winding forming effect of the stator core and further affecting the overall manufacturing efficiency of the stator core. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a winding device for an iron core, which can achieve heat dissipation by blowing air to the heating part of the winding machine in a hot environment, and the blowing part and the blowing intensity can be adjusted according to the heating temperature of the winding machine.

[0005] A winding device for an iron core of the present invention comprises a conveyor belt for conveying silicon steel strips and a winding module for winding the silicon steel strips; a cooling module is fixedly arranged on one side of the conveyor belt and the winding module, a plurality of cooling channels are arranged in the cooling module to release cooling gas toward the silicon steel strips at different positions, and a temperature sensing component and an opening and closing component are fixedly arranged in each cooling channel; the opening and closing component controls the opening and closing and size of the corresponding cooling channel; the temperature sensing component is fixedly connected to the corresponding opening and closing component, and a plurality of temperature sensing components sense the temperature at different positions on the conveyor belt and the winding module, and adjust the movement of the corresponding opening and closing components according to the temperature to control the opening and closing and size of the cooling channel, so as to adjust the cooling effect on different positions on the conveyor belt and the winding module. Compared with the prior art, the beneficial effect of the present invention lies in that the temperature sensing component senses the temperature of different positions on the conveyor belt and the winding module, and adjusts the movement of the corresponding opening and closing components according to the temperature to control the opening and closing and size of the cooling channel, so that when the silicon steel strip is transported and wound on the winding equipment, the positions with higher heat generation are subjected to a stronger cooling effect of the cooling gas, while the positions with lower heat generation are subjected to less cooling gas, so that the temperature of each position is maintained at a suitable working temperature to ensure the processing effect and yield rate of the iron core in the finished product, to prevent the uniform cooling from causing uneven temperatures in various parts of the silicon steel strip after final cooling, so that the high-temperature part of the silicon steel strip is still heated and expanded, resulting in excessive gaps between the silicon steel coils on the final iron core, thereby affecting the processing effect and processing efficiency of the iron core.

[0006] As a further improvement of the present invention, the cooling module includes a cooling member; the outer periphery of the cooling member is a closed ventilation cavity, the ventilation cavity is connected to an exhaust fan, and the exhaust fan draws air from the outside to the ventilation cavity; the cooling member is provided with an air outlet on one side close to the silicon steel strip, and the number of the air outlets is multiple, and an exhaust fan is provided in each air outlet, so that when the exhaust fan rotates, the air outlet blows air to the outside; the temperature sensing component and the opening and closing component are arranged on one side of the air outlet, and the number of the temperature sensing components and the opening and closing components is consistent with the number of the air outlets, so that the temperature sensing component controls the opening size of the air outlet through the opening and closing component.

[0007] As a further improvement of the present invention, the shape of the air outlet is circular; the opening and closing component includes a baffle, the shape of the baffle is semicircular, and the radius is equal to or greater than the radius of the air outlet, and the circle formed by two baffles closes the air outlet; the two baffles are slidably connected to the air outlet on one side close to the air outlet, and the two baffles are fixedly connected to the temperature sensing component so that the temperature sensing component controls the two baffles to move away from or towards each other.

[0008] As a further improvement of the present invention, an adjusting cavity is respectively provided on one side of the two baffles away from the air outlet; the adjusting cavity is surrounded by a plurality of rigid heat conductive plates; the temperature sensing component includes two airbags and two connecting rods; the two airbags are respectively symmetrically arranged in the two adjusting cavities, each airbag is fixedly connected to the inner wall of the adjusting cavity on the side away from the air outlet, the volume of the airbag is smaller than the volume of the adjusting cavity, the airbag is made of elastic material, and the inside of the airbag is filled with gas so that the airbag has the ability of thermal expansion and contraction; the two connecting rods are respectively symmetrically arranged in the two adjusting cavities, one end of each connecting rod is fixedly connected to one end of the airbag close to the air outlet, and the other end passes through the baffle close to it and is fixedly connected to another baffle, and the connecting rod is slidably connected to the baffle close to it; when the airbag is in a free state, the planes of the two baffles fit together to close the air outlet. Compared with the prior art, the present invention adopts an airbag, which is sensitive to temperature changes. High temperature will cause the airbag to expand, and the degree of expansion of the airbag is different at different temperatures. The higher the temperature, the greater the degree of expansion of the airbag. At this time, the greater the distance between the two baffles, the larger the opening range of the air outlet, and the greater the wind speed and air volume blown out from the air outlet, so as to provide a better cooling effect. Under the control of the airbag, the higher the temperature, the better the cooling effect of the air outlet on the silicon steel strip, so that multiple air outlets automatically adopt different wind speeds and air volumes for the silicon steel strip in different temperature environments, so that each part of the silicon steel strip can be cooled to an appropriate temperature, so as to prevent the temperature of a certain part of the silicon steel strip from being too high or too low due to uniform cooling, affecting the processing of the iron core.

[0009] As a further improvement of the present invention, the cooling element includes a ventilation pipe, which is in the shape of a tube bent upward, with a horizontal end of the ventilation pipe horizontally arranged on one side of the conveyor belt and a vertical end of the ventilation pipe arranged on one side of the winding module.

[0010] As a further improvement of the present invention, the cooling member is in the shape of a hood, and the cooling member is sleeved on the outer periphery of the conveyor belt and the coil module; the air outlets are opened on multiple surfaces of the cooling member close to the silicon steel strip. Compared with the tubular cooling member, the hood-shaped cooling member is sleeved on the outer periphery of the conveyor belt and the coil module, so that the air outlets can blow air to the silicon steel strip from multiple angles and directions to cool it down, so as to prevent the ventilation pipe from having too single a cooling angle and direction for the silicon steel strip and the silicon steel coil, resulting in incomplete cooling, thereby ensuring the forming effect of the winding of the iron core.

Compared with the prior art, water spraying reduces the temperature of the silicon steel strip being transported and washes away dust and impurities on the surface of the silicon steel strip to prevent the winding of the silicon steel strip from being affected, so that the silicon steel strips are not tightly attached to each other.

[0012] As a further improvement of the present invention, a cleaning brush is provided on the conveyor belt, and the upper end of the cleaning brush is fixedly connected to the output end of the cleaning cylinder, so that the cleaning cylinder controls the cleaning brush to move toward or away from the silicon steel strip.

DETAILED DESCRIPTION

[0026] Specific embodiment 1: Please refer to Figure 1-8 A core winding device includes a feeding module 1, a pressing module 3, a cutting module 4, a winding module 6 and a cooling module 7.

[0027] The unloading module 1 is used to fix the silicon steel strips of equal width in coils; a lever is arranged between the unloading module 1 and the winding module 6, and the silicon steel strip is transmitted to the winding module 6 through the lever. There is a tension sensor on the lever, and the unloading module 1 has different unloading speeds according to the different tensions of the silicon steel strip. The higher the lever is lifted, the faster the unloading speed is. When the lever falls to the ground, the unloading module 1 stops unloading; the unloading module 1 continuously provides the silicon steel strip to the winding module 6 through the lever;

[0028] The winding module 6 is used to fix the iron core 8. When working, the iron core 8 rotates around the axis so that the silicon steel strip provided by the unwinding module 1 is continuously wound on the iron core;

[0029] The clamping module 3 is arranged between the unloading module 1 and the winding module 6, and the clamping module 3 includes a clamping block and a clamping cylinder; the clamping block is arranged on the upper side of the silicon steel strip, and the upper end of the clamping block is connected to the output end of the clamping cylinder, so that the clamping cylinder controls the clamping block to move toward or away from the silicon steel strip; when working, the clamping cylinder controls the clamping block to move toward the direction of the silicon steel strip, so that the silicon steel strip transported to the winding module 6 is flattened after being flattened by the clamping block, so as to reduce the gap between the wound silicon steel coils.

[0030] The cutting module 4 is arranged between the pressing module 3 and the winding module 6 so that after the silicon steel strip wound on the iron core 8 in the winding module 6 reaches the specification, the cutting module 4 cuts the silicon steel strip being transported to complete the winding.

[0031] A feeding wheel 2 is provided between the unloading module 1 and the pressing module 3, and the rotation of the feeding wheel 2 drives the transportation of the silicon steel strip.

[0032] A feeding pallet rack 5 is provided between the cutting module 4 and the winding module 6. The movement of the feeding pallet rack 5 drives the transportation of the silicon steel strip, so that the silicon steel strip can be transported to the winding module 6 to complete the winding after being cut.

[0033] It should be noted that the working methods and working principles of the devices and structures in the discharge module 1, the pressing module 3, the cutting module 4 and the winding module 6 are all prior arts, and therefore will not be elaborated in this application.

[0034] The cooling module 7 is arranged on one side of the transportation route of the silicon steel strip between the winding module 6 and the unwinding module 1 to the winding module 6. The cooling module 7 is used to cool the silicon steel strip to prevent the silicon steel strip and the iron core 8 from expanding due to high temperature when the silicon steel strip is wound in a hot environment, resulting in a gap between the wound silicon steel strip;

[0035] The cooling module 7 includes a cooling element and an opening and closing assembly.

[0036] The cooling member is in the shape of a tube that bends upward, and includes a vent pipe 71. The horizontal end of the vent pipe 71 is horizontally arranged on one side of the silicon steel strip being transported, and the vertical end of the vent pipe 71 is arranged on one side of the winding module 6. One end of the vent pipe 71 is closed, and the other end is connected to the exhaust fan, so that the exhaust fan draws air from the outside and transports gas into the vent pipe 71. The vent pipe 71 is provided with an air outlet 72 on one side close to the silicon steel strip, and the number of the air outlet 72 is multiple; each air outlet 72 has a An exhaust fan is provided so that when the exhaust fan rotates, the air outlet 72 blows air outward; the length of the horizontal end of the ventilation pipe 71 is greater than the length of the transportation route of the silicon steel strip from the unloading module 1 to the winding module 6, so that after the exhaust fan draws gas from the outside and inputs it into the ventilation pipe, the air pressure in the ventilation pipe 71 becomes larger, thereby blowing air toward the air outlet 72 to drive the rotation of the exhaust fan in the air outlet 72, so that the air outlet 72 blows air toward the side of the winding module 6, so as to reduce the temperature of the silicon steel strip during transportation and winding.

[0037] The number of the opening and closing components is consistent with the number of the air outlet holes 72. The opening and closing components are arranged on one side of the air outlet holes 72, and the opening and closing components control the opening and closing of the air outlet holes 72.

[0038] The opening and closing assembly includes a left shield 73 and a right shield 74;

[0039] The left shielding plate 73 and the right shielding plate 74 are semicircular in shape, and the radius is equal to or greater than the radius of the air outlet 72, so that the circle formed by the left shielding plate 73 and the right shielding plate 74 can close the air outlet 72;

[0040] A left regulating chamber 731 is provided on the side of the left shielding plate 73 away from the air outlet 72. The left regulating chamber 731 is surrounded by a plurality of rigid heat-conducting plates. A left airbag 733 is fixedly connected to the inner wall of the left regulating chamber 731 away from the air outlet 72. The volume of the left airbag 733 is smaller than that of the left regulating chamber 731. The left airbag 733 is made of elastic material and is filled with gas, so that the left airbag 733 has the ability to expand and contract rightward in the left regulating chamber 731 when heated and cooled.

[0041] The right side of the left airbag 733 is fixedly connected with a left connecting rod 732; one side of the left connecting rod 732 is fixedly connected to the left airbag 733, and the other side of the left connecting rod 732 passes through the left shielding plate 73 and is fixedly connected to the right shielding plate 74. The left connecting rod 732 is slidably connected to the left shielding plate 73, so that the thermal expansion and contraction of the left airbag 733 controls the left and right movement of the right shielding plate 74;

[0042] A right regulating chamber 741 is provided on one side of the right shielding plate 74 away from the air outlet 72. The right regulating chamber 741 is surrounded by a plurality of rigid heat-conducting plates. A right airbag 743 is fixedly connected to the inner wall of the right regulating chamber 741 away from the air outlet 72. The volume of the right airbag 743 is smaller than that of the right regulating chamber 741. The right airbag 743 is made of elastic material and is filled with gas, so that the right airbag 743 has the ability to expand and contract to the left in the right regulating chamber 741 when heated and cooled.

[0043] The left side of the right airbag 743 is fixedly connected with a right connecting rod 742; one side of the right connecting rod 742 is fixedly connected to the right airbag 743, and the other side of the right connecting rod 742 passes through the right baffle 74 and is fixedly connected to the left baffle 73; the right connecting rod 742 is slidably connected to the right baffle 74, so that the thermal expansion and contraction of the right airbag 743 controls the left and right movement of the left baffle 73.

[0044] It should be noted that when the left airbag 733 and the right airbag 743 are in a free state, the planes of the left baffle 73 and the right baffle 74 fit together, and at this time the left baffle 73 and the right baffle 74 close the air outlet 72; at this time, when the left airbag 733 and the right airbag 743 are inflated, the left connecting rod 732 will push the right baffle 74 to move to the right, and the right connecting rod 742 will push the left baffle 73 to move to the left, and at this time the air outlet 72 is opened; and the greater the degree of expansion of the left airbag 733 and the right airbag 743, the larger the range of opening of the air outlet 72, and at this time, the greater the airflow and wind speed blown out from the air outlet 72.

[0045] A water spray device is arranged between the feeding wheel 2 and the lever, and the water spray port of the water spray device is directed toward the silicon steel strip being transported. The water spray device is connected to an external water pump so that when working, the water pump pumps water out through the water spray device, and the water spray device sprinkles clean water onto the silicon steel strip being transported.

[0046] A cleaning brush is provided on the upper side of the feeding pallet rack 5, and the upper end of the cleaning brush is fixedly connected to the output end of the cleaning cylinder so that the cleaning cylinder controls the cleaning brush to move towards or away from the silicon steel strip; during operation, the cleaning cylinder controls the lower end of the cleaning brush to approach the silicon steel strip to scrape off moisture, oil, dust and other impurities on the surface of the silicon steel strip to improve the fit between the silicon steel strips of the silicon steel coil in the winding module 6.

[0047] Working principle: when coiling, the silicon steel strips of equal width are fixed on the unloading module 1, and the silicon steel strips are transported outward from the unloading module 1. The silicon steel strips are transported by levers, and the transportation speed of the silicon steel strips is affected by the height of the lever. The higher the lever is lifted, the faster the unloading speed is. When the lever falls to the ground, the unloading module 1 stops unloading; after the silicon steel strips leave the lever, the water spraying device sprays clean water on the silicon steel strips to reduce the temperature of the silicon steel strips during transportation, and the feeding wheel 2 rotates to continuously transport the silicon steel strips. At this time, the cutting module 4 does not work. When the silicon steel strips pass through the feeding pallet rack 5, the cleaning cylinder controls the lower end of the cleaning brush to approach the silicon steel strips to scrape and clean the moisture, oil, dust and other impurities on the surface of the silicon steel strips; under the transportation of the feeding pallet rack 5, the silicon steel strips enter the winding module 6. At this time, the iron core 8 rotates around the axis so that the silicon steel strips provided by the unloading module 1 are continuously wound on the iron core 8, and the winding of the silicon steel strips has been completed;

[0048] When the silicon steel strip is transported in a hot and high temperature environment, the cooling effect of simply spraying clean water is generally poor, and the clean water is scraped off before entering the winding module 6. The winding module 6 will emit heat when working, so that the temperature of the silicon steel strip is higher, thereby affecting the fit between the wound silicon steel strips; at this time, the cooling module 7 works;

[0049] The high temperature causes the left airbag 9733 and the right airbag 743 to expand. At this time, the left connecting rod 732 will push the right baffle 74 to move to the right, and the right connecting rod 742 will push the left baffle 73 to move to the left. At this time, the air outlet 72 is opened, and the exhaust fan draws air from the outside to make the exhaust fan rotate so that the air outlet 72 blows air toward the silicon steel strip. The airflow blows on the silicon steel strip to accelerate the evaporation of moisture on the surface of the silicon steel strip, thereby achieving a rapid cooling effect; and in the winding module 6, the device for controlling the rotation of the iron core 8 around the axis generates heat, and after the silicon steel strip is continuously wound on the iron core, the air permeability of the silicon steel strip becomes worse and worse, and the silicon steel strip is naturally My heat dissipation efficiency is reduced. At this time, the temperature of the silicon steel strip in the winding module 6 is greater than the temperature of the silicon steel strip in other modules. At this time, the left air bag 9733 and the right air bag 743 near the winding module 6 are affected by the higher temperature and expand to a greater extent, so that the left connecting rod 732 pushes the right baffle 74 to move a greater distance to the right, and the right connecting rod 742 pushes the left baffle 73 to move a greater distance to the left, so that the opening range of the air outlet 72 is greater than the opening range of the air outlets on other modules, so that the wind speed and air volume of the air outlet 72 near the winding module 6 are greater, so as to speed up the cooling of the winding module 6.

[0050] Specific embodiment 2: Different from specific embodiment 1, the cooling member is shaped like a cover, and the cooling member is mounted on the periphery of the transportation route of the silicon steel strip from the discharge module 1 to the winding module 6; the periphery of the cooling member is a closed ventilation cavity, and the ventilation cavity is connected to an exhaust fan; the air outlet 72 is opened on the surface of the cooling member, so that when the air outlet 72 is opened during operation, air can be blown to the silicon steel strip from multiple angles and directions to cool it down; the internal structure of the air outlet 72 and the setting of the opening and closing component on the air outlet 72 are the same as those in specific embodiment 1.

[0051] During operation, there are air outlets 72 on the upper side and front and rear sides of the silicon steel strip. At this time, due to the different heat generation and heat dissipation in different parts, the heat generation of the winding module 6 is the fastest and the heat dissipation is the slowest. At this time, the temperature of the winding module 6 is the highest, and since the heat dissipation effect of the silicon steel strip closest to the iron core 8 is the worst, the closer to the iron core 8, the higher the temperature of the silicon steel strip. At this time, the opening range of the air outlet 72 close to the iron core 8 is the largest, the air volume and wind speed are the largest, and the heat dissipation effect is good, so that the cooling module 7 can dissipate heat more accurately for the parts that need heat dissipation. The air outlet speed and air volume of the air outlet 72 are both controlled by heat, which is convenient and labor-saving, and the cooling is targeted, ensuring the cooling of various parts when the silicon steel strip is wound, so as to prevent the ventilation pipe 71 from having too single cooling angle and direction for the silicon steel strip and silicon steel coil, resulting in incomplete cooling, thereby ensuring the forming effect of the winding of the iron core.
