[0001] The invention relates to the technical field of insulator processing, and in particular to a composite suspension insulator core rod processing system. Background Art

[0002] Composite insulators include core rods, sheaths, sheds, hardware and other parts. The core rod material is mainly epoxy glass fiber, and the sheath and shed materials are high-temperature vulcanized silicone rubber. It is characterized by small head size, light weight, high strength and large creepage distance, which can save metal materials and reduce line costs.

[0003] During the molding process of the composite insulator, the core rod needs to be polished and then the dust on its surface needs to be cleaned to avoid poor bonding. After cleaning, the core rod cannot be prevented from absorbing moisture and needs to be dried in time.

[0021] 2. The pump body sucks the water vapor generated by drying inside the drying chamber through the second air duct, air cylinder and air hole to prevent the core rod body from being wetted for the second time;

[0022] 3. Drying is carried out inside the drying chamber to improve the utilization efficiency of heat energy and avoid the influence of external dust and other impurities. At the same time, gas is delivered from one end of the drying chamber and sucked from the other end to form a high-temperature airflow along the axial length direction of the mandrel body to ensure the drying effect;

[0023] 4. A single pump body can simultaneously transport gas and pump air, thus reducing energy consumption;

[0024] 5. When the solenoid valve is in the closed state, the pump body only sucks the drying chamber, which can extract the residual water vapor and further improve the drying efficiency;

[0025] 6. The airflow generated during the drying process will drive the sliding sleeve to rotate through the fan blades and the round sleeve, thereby driving the core rod body to rotate, increasing the contact area between the core rod body and the high-temperature gas, accelerating the drying progress, and improving the uniformity of drying;

[0026] 7. When the ejection speed of the high-temperature gas is increased, the gas drives the sliding sleeve to move toward the square plate through the circular sleeve, and the sliding sleeve contracts through the first circular ring extrusion spring; when the high-temperature gas stops ejecting, the return elastic force of the spring causes the sliding sleeve to return to its original position, thereby realizing the back-and-forth swing of the core rod body, further accelerating the drying progress;

[0027] 8. When the high-temperature gas is sprayed from the wind hood to the drying chamber, the guide strip will drive the rotating ring to rotate inside the wind hood, thereby driving the guide strip to rotate. The guide strip will stir the airflow, expand the range of wind force, avoid always acting on the same position, and further improve the uniformity of drying. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments 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 creative work are within the scope of protection of the present invention.

[0039] The present invention provides Figures 1 to 9A composite suspension insulator core rod processing system shown includes a frame 1 and a drying mechanism, a chain 2 is provided on one side of the frame 1, a rotating shaft 31 is rotatably provided at both upper and lower ends of the frame 1, a gear 32 is fixedly connected to the rotating shaft 31, and the two gears 32 are connected by transmission through the chain 2, a motor 33 is fixedly connected to the frame 1, and one of the rotating shafts 31 is fixedly connected to the driving shaft of the motor 33. A square plate 3 for positioning the core rod body 34 is fixedly connected to the chain 2, and the square plate 3 can be fixed to the chain 2 through a connecting rod, so that the square plate 3 can be adaptively rotated at the arc of the chain 2, and a plurality of square plates 3 are provided, and the plurality of square plates 3 are evenly distributed.

[0040] Considering that in the prior art, when the core rod body 34 is dried, the core rod body 34 is often stacked together and the position remains unchanged during drying, which easily leads to a longer drying time for the stacked contact part of the core rod body 34 than for other parts, reducing the drying effect. In order to improve the drying effect, the present invention is provided with a drying mechanism and a chain 2 and other structures, and the drying mechanism includes a U-shaped frame 4, a partition 5 and a drying chamber 8. The outer wall of the U-shaped frame 4 is fixedly connected with a bracket 29, and the bracket 29 is fixedly connected to the frame 1. The bracket 29 is provided to fix the position of the U-shaped frame 4. Two partitions 5 are provided, and the two partitions 5 are respectively slidably attached to the upper and lower ends of the U-shaped frame 4, and the square plate 3 is attached to the U-shaped frame 4. A drying chamber 8 is formed between the U-shaped frame 4, the two partitions 5 and the square plate 3.

[0041] When the two partitions 5 are staggered from the U-shaped frame 4, it is convenient for the core rod body 34 to enter the interior of the U-shaped frame 4 during transportation; when the two partitions 5 cover the upper and lower ends of the U-shaped frame 4 respectively, a drying chamber 8 is formed, which is convenient for drying the core rod body 34.

[0042] In order to adjust the positions of the two partitions 5, a movable frame 6 is fixedly connected between the two partitions 5, and the movable frame 6 is U-shaped. An electric push rod 7 is fixedly connected to the outer wall of the U-shaped frame 4, and the movable frame 6 is fixedly connected to the telescopic end of the electric push rod 7. The positions of the two partitions 5 are adjusted by the electric push rod 7.

[0043] A round rod 9 is fixedly connected to one side of the square plate 3 close to the U-shaped frame 4, and a sliding sleeve 10 is rotatably provided at one end of the round rod 9 away from the square plate 3. A clamp 11 for clamping the mandrel body 34 is fixedly connected to the sliding sleeve 10. The clamp 11 includes a plurality of clamping teeth and at least three. The plurality of clamping teeth are evenly distributed around the sliding sleeve 10. The clamping teeth have a certain elasticity and can clamp and fix the mandrel body 34. When feeding, the mandrel body 34 is inserted into the clamp 11, and the end of the mandrel body 34 abuts against the sliding sleeve 10. The plurality of square plates 3 and other structures are provided, and a plurality of mandrel bodies 34 can be transported at the same time, which is convenient for continuous processing.

[0044] Specifically, the mandrel body 34 to be dried is inserted into the clamp 11 at the loading station, and the end of the mandrel body 34 abuts against the sliding sleeve 10 to complete the loading operation. The motor 33 drives the rotating shaft 31 fixedly connected to its driving shaft to rotate, and with the cooperation of the two gears 32, the chain 2 rotates, and drives the mandrel body 34 to move through the square plate 3, the round rod 9 and the sliding sleeve 10.

[0045] The single core rod body 34 is dried inside the drying chamber 8 to avoid the core rod body 34 from being stacked, thereby improving the drying effect.

[0046] When used specifically, the U-shaped frame 4 can be set as a drying station, the lower position of the U-shaped frame 4 can be set as a loading station, and the upper position of the U-shaped frame 4 can be set as a retrieving station, which can also be adjusted according to specific usage conditions. With the cooperation of the chain 2, the square plate 3 and other structures, loading, drying, retrieving and other operations can be performed simultaneously, realizing continuous processing and improving production efficiency.

[0047] A wind hood 16 for conveying high-temperature gas is fixedly connected to the U-shaped frame 4, and an air bag 27 is fixedly connected to the outer wall of the U-shaped frame 4. The air bag 27 has elastic force to restore deformation. The air bag 27 is connected to a first air duct 22, and the end of the first air duct 22 away from the air bag 27 is connected to the wind hood 16; a wind hole 21 for sucking gas is opened on the square plate 3, and the wind hood 16 and the wind hole 21 are relatively distributed, and a plurality of wind holes 21 can be provided.

[0048] The U-shaped frame 4 is provided with a wind circulation assembly on the outside, which includes a wind tube 20, a second wind duct 24, a processing box 25 and a pump body 26. The processing box 25 and the pump body 26 are both fixedly connected to the outer wall of the U-shaped frame 4, and the air inlet end of the pump body 26 is connected to the processing box 25. The processing box 25 is provided with a heating device and a condensing device inside. The heating device includes structures such as an electric heating plate, which can quickly heat the gas passing through the processing box 25 to form high-temperature gas; the condensing device includes structures such as a condensing plate, which can condense the water vapor generated by drying. After the gas is processed by the condensing device, the heating device can also dry the residual moisture. The heating device and the condensing device are both existing common technologies and will not be described in detail here. In addition, a filtering device can be provided, including structures such as a filter screen, which can filter the residual impurities and can be adjusted according to specific usage conditions.

[0049] The air outlet end of the pump body 26 is connected to the air bag 27. The wind tube 20 is located on the side of the square plate 3 facing away from the U-shaped frame 4. The wind tube 20 is connected and cooperated with the wind hole 21. One end of the second air duct 24 is connected to the wind tube 20, and the other end of the second air duct 24 is connected to the processing box 25. The second air duct 24 is made of hard material and can fix the position of the wind tube 20. When one of the square plates 3 corresponds to the position of the U-shaped frame 4, the wind tube 20 is attached to the square plate 3 and connected to the wind hole 21. During specific use, a rubber sealing pad can be set on the wind tube 20 to improve the sealing performance of the docking with the square plate 3 and reduce wear.

[0050] Specifically, the telescopic end of the electric push rod 7 is controlled to extend, and the upper and lower partitions 5 are driven to move through the moving frame 6. The upper and lower partitions 5 are staggered with the U-shaped frame 4, so that the upper and lower ends of the U-shaped frame 4 are exposed, which facilitates the core rod body 34 to enter the interior of the U-shaped frame 4 during the conveying process.

[0051] The core rod body 34 is driven to move by the motor 33, the chain 2 and other structures. When the square plate 3 corresponding to the core rod body 34 corresponds to the position of the U-shaped frame 4, the core rod body 34 enters the interior of the U-shaped frame 4, and then the telescopic end of the electric push rod 7 is controlled to be recovered, and the upper and lower partitions 5 are driven to reset through the moving frame 6, and the upper and lower ends of the U-shaped frame 4 are closed, and a drying chamber 8 is formed between the U-shaped frame 4, the two partitions 5 and the square plate 3. At the same time, the air duct 20 is attached to the side wall of the square plate 3 (refer to Figure 6 ), the air cylinder 20 and the air hole 21 are in a connected state.

[0052] Start the heating device and condensing device inside the processing box 25, start the pump body 26 at the same time, open the solenoid valve 23, and the pump body 26 transports the heated high-temperature gas to the wind cover 16 through the air bag 27 and the first air duct 22, and sprays it into the drying chamber 8 to dry the core rod body 34.

[0053] At the same time, the pump body 26 sucks the water vapor generated by drying inside the drying chamber 8 through the second air duct 24, the air cylinder 20, and the air hole 21 to prevent the core rod body 34 from being wetted for the second time, and the sucked gas is condensed and dried inside the processing box 25 to achieve the dehumidification effect.

[0054] Drying is performed inside the drying chamber 8 to improve the utilization efficiency of heat energy and avoid the influence of external impurities such as dust. At the same time, gas is transported from one end of the drying chamber 8 and sucked from the other end to form a high-temperature airflow along the axial length direction of the core rod body 34 to ensure the drying effect.

[0055] A single pump body 26 simultaneously delivers gas and performs suction, thereby reducing energy consumption.

[0056] In order to improve the drying efficiency, a solenoid valve 23 is fixedly installed on the first air duct 22 .

[0057] Specifically, during the drying process, the solenoid valve 23 is closed, and the high-temperature gas delivered by the pump body 26 will enter the interior of the airbag 27 and accumulate inside the airbag 27, causing the airbag 27 to expand and become larger. When the airbag 27 expands to a certain extent, the solenoid valve 23 opens, and under the action of the contraction elastic force of the airbag 27, the speed at which the high-temperature gas is ejected from the wind hood 16 can be increased; then the solenoid valve 23 is closed, the airbag 27 expands again, and the above steps are repeated to periodically increase the ejection speed of the high-temperature gas and improve the drying efficiency; at the same time, impurities remaining on the outside of the core rod body 34 can also be blown away.

[0058] A pressure sensor may be provided inside the airbag 27 to monitor the pressure inside the airbag 27 to prevent the airbag 27 from bursting due to excessive gas; and a controller may be provided to connect between the pressure sensor and the solenoid valve 23 to control the solenoid valve 23. The controller and its working principle are both existing common technologies and will not be elaborated here.

[0059] In addition, when the solenoid valve 23 is in a closed state, the pump body 26 only pumps the drying chamber 8, thereby extracting the residual water vapor and further improving the drying efficiency.

[0060] By setting up structures such as the chain 2, the drying chamber 8 and the airbag 27, a single core rod body 34 is dried inside the drying chamber 8 to avoid stacking of the core rod bodies 34, thereby improving the quality of drying. Loading, drying, and taking out of materials can be performed simultaneously to achieve continuous processing. In addition, the ejection speed of the high-temperature gas is periodically increased to improve the drying efficiency.

[0061] The sliding sleeve 10 is fixedly connected with a circular sleeve 30, and the outer ring of the circular sleeve 30 is fixedly connected with a fan blade 12, and the fan blade 12 is provided in a plurality, and the plurality of fan blades 12 are evenly distributed around the circular sleeve 30. Specifically, the airflow generated during the drying process will drive the sliding sleeve 10 to rotate through the fan blades 12 and the circular sleeve 30, thereby driving the core rod body 34 to rotate, increasing the contact area between the core rod body 34 and the high-temperature gas, accelerating the drying progress, and improving the uniformity of the drying.

[0062] The sliding sleeve 10 can be rotated on the round rod 9 or can slide on the round rod 9. The round rod 9 is slidably provided with a first ring 13 and a second ring 14, the first ring 13 abuts on the sliding sleeve 10, and the second ring 14 abuts on the square plate 3. A spring 15 is sleeved on the round rod 9, one end of the spring 15 is fixedly connected to the first ring 13, and the other end of the spring 15 is fixedly connected to the second ring 14. The resetting elastic force of the spring 15 makes the first ring 13 abut on the sliding sleeve 10, which can prevent the sliding sleeve 10 from rotating freely on the round rod 9; and the elastic force of the spring 15 is appropriate, which does not affect the airflow generated during the drying process, which drives the sliding sleeve 10 to rotate through the fan blades 12 and the round sleeve 30.

[0063] In addition, when the ejection speed of the high-temperature gas is increased, the gas drives the sliding sleeve 10 to move toward the square plate 3 through the circular sleeve 30, and the sliding sleeve 10 contracts by squeezing the spring 15 through the first circular ring 13; when the high-temperature gas stops ejecting, the restoring elastic force of the spring 15 causes the sliding sleeve 10 to reset, thereby realizing the back and forth swing of the core rod body 34, further accelerating the drying progress.

[0064] A swivel 17 is rotatably arranged inside the wind cover 16, a round block 18 is arranged inside the swivel 17, the swivel 17 and the round block 18 are arranged concentrically, a guide bar 19 is fixedly arranged between the swivel 17 and the round block 18, and the guide bar 19 is arranged obliquely. Specifically, when the high-temperature gas is sprayed from the wind cover 16 to the drying chamber 8, the swivel 17 is driven to rotate inside the wind cover 16 through the guide bar 19, thereby driving the guide bar 19 to rotate, and the guide bar 19 stirs the airflow, expands the range of wind force, avoids always acting on the same position, and further improves the uniformity of drying.

[0065] In order to facilitate the drying of the contact position between the core rod body 34 and the sleeve 10, a through groove 28 is opened at the end of the sleeve 10 away from the round rod 9 to facilitate the flow of gas at the contact position between the core rod body 34 and the sleeve 10. At the same time, the sleeve 10 can be made of heat-conducting materials such as but not limited to copper alloys.

[0066] Working principle: insert the core rod body 34 to be dried into the clamp 11 at the loading station, and the end of the core rod body 34 abuts against the sliding sleeve 10 to complete the loading operation. At the same time, control the telescopic end of the electric push rod 7 to extend, and drive the upper and lower partitions 5 to move through the moving frame 6. The upper and lower partitions 5 are staggered with the U-shaped frame 4, so that the upper and lower ends of the U-shaped frame 4 are exposed, which is convenient for the core rod body 34 to enter the interior of the U-shaped frame 4 during the transportation process.

[0067] The motor 33 drives the rotating shaft 31 fixedly connected to its driving shaft to rotate. With the cooperation of the two gears 32, the chain 2 rotates and drives the core rod body 34 to move through the square plate 3, the round rod 9 and the sliding sleeve 10; when the position of the square plate 3 corresponds to that of the U-shaped frame 4, the square plate 3 fits on the U-shaped frame 4, and the core rod body 34 enters the interior of the U-shaped frame 4. Then, the telescopic end of the electric push rod 7 is controlled to be recovered, and the upper and lower partitions 5 are driven to reset through the moving frame 6, and the upper and lower ends of the U-shaped frame 4 are closed, and a drying chamber 8 is formed between the U-shaped frame 4, the two partitions 5 and the square plate 3. At the same time, the air duct 20 fits on the side wall of the square plate 3 (refer to Figure 6 ), the air cylinder 20 and the air hole 21 are in a connected state.

[0068] Start the heating device and condensing device inside the processing box 25, start the pump body 26 at the same time, open the solenoid valve 23, and the pump body 26 transports the heated high-temperature gas to the wind cover 16 through the air bag 27 and the first air duct 22, and sprays it to the drying chamber 8 to dry the core rod body 34; at the same time, the pump body 26 sucks the water vapor generated by drying inside the drying chamber 8 through the second air duct 24, the wind tube 20, and the air hole 21 to prevent the core rod body 34 from being wetted for the second time, and the sucked gas is condensed and dried inside the processing box 25 to achieve the dehumidification effect.

[0069] The gas is delivered from one end of the drying chamber 8 and sucked from the other end, forming a high-temperature airflow along the axial length direction of the core rod body 34 to ensure the drying effect.

[0070] During the drying process, the solenoid valve 23 is closed, and the high-temperature gas delivered by the pump body 26 will enter the interior of the airbag 27 and accumulate inside the airbag 27, causing the airbag 27 to expand and become larger. When the airbag 27 expands to a certain extent, the solenoid valve 23 is opened, and under the action of the contraction elastic force of the airbag 27, the speed at which the high-temperature gas is ejected from the wind hood 16 is increased; then the solenoid valve 23 is closed, the airbag 27 expands again, and the above steps are repeated to periodically increase the ejection speed of the high-temperature gas and improve the drying efficiency; at the same time, impurities remaining on the outside of the core rod body 34 can also be blown away.

[0071] When the electromagnetic valve 23 is in a closed state, the pump body 26 only pumps the drying chamber 8, thereby pumping out the residual water vapor and further improving the drying efficiency.

[0072] The airflow generated during the drying process will drive the sliding sleeve 10 to rotate through the fan blades 12 and the circular sleeve 30, thereby driving the core rod body 34 to rotate, increasing the contact area between the core rod body 34 and the high-temperature gas, and accelerating the drying process.

[0073] When the ejection speed of the high-temperature gas is increased, the gas drives the sliding sleeve 10 to move toward the square plate 3 through the circular sleeve 30, and the sliding sleeve 10 contracts by squeezing the spring 15 through the first circular ring 13; when the high-temperature gas stops ejecting, the restoring elastic force of the spring 15 resets the sliding sleeve 10, thereby realizing the back and forth swing of the core rod body 34, further accelerating the drying progress.

[0074] In addition, when the high-temperature gas is sprayed from the wind hood 16 to the drying chamber 8, the guide strip 19 will drive the swivel 17 to rotate inside the wind hood 16, thereby driving the guide strip 19 to rotate. The guide strip 19 stirs the airflow, expands the range of wind action, avoids always acting on the same position, and improves the drying effect.

[0075] After the drying is completed, the telescopic end of the electric push rod 7 is controlled to extend, and the upper and lower partitions 5 are driven to move through the movable frame 6, so that the upper and lower ends of the U-shaped frame 4 are exposed, which is convenient for the chain 2 and other structures to drive the core rod body 34 that has completed the drying process to move. When the core rod body 34 enters the material taking station and the chain 2 stops rotating, the core rod body 34 can be removed to realize the material taking operation; and during the material taking operation, other core rod bodies 34 can be loaded and dried to realize continuous production.
