Description

Technical Field

[0001] The utility model relates to the technical field of electric heating tubes, in particular to a silicone oil filling device for electric heating tubes. Background Technique

[0002] An electric heating tube is a tubular electric heating element. After the finished product of the electric heating tube, since its internal insulating material is magnesium oxide, it is extremely easy to get damp and cause the insulation performance to decrease. Therefore, during the transfer process or storage, silicone oil will be added into the tube orifice to play a role in isolating air, preventing moisture in the air from entering the electric heating tube, reducing the insulation of the electric heating tube, or even reducing it to zero, resulting in the electric heating tube being unable to be used normally.

[0003] The existing method of adding silicone oil is generally to stand the electric heating tube upright with the tube orifice facing upwards. There is generally a gap of 5 - 10 cm reserved between the magnesium oxide in the tube orifice of the electric heating tube and the port. Then, silicone oil is added into the tube orifice gap manually. However, manual addition is inevitably difficult to control properly, which may lead to too little or too much silicone oil being added. When it is too little, it cannot effectively isolate the moisture in the air. When it is too much, the silicone oil will overflow from the tube orifice and spill onto the ground, causing environmental pollution and increasing the cleaning difficulty of the finished tube.

[0004] Therefore, further improvement can be made. Content of the Utility Model

[0005] To solve the problems mentioned above, the utility model provides the following technical solution: A silicone oil filling device for electric heating tubes, including a base. Two limiting rods are fixedly installed at the top side of the base near the corners. The top of the limiting rods is fixedly installed with a top plate. A screw rod is rotatably connected to the top of the base and located between the two limiting rods, and the top of the screw rod is rotatably connected to the middle of the top plate. A threaded sleeve is threadedly sleeved on the outer side of the screw rod. Both sides of the threaded sleeve are fixedly installed with support plates. The end of the support plate is fixedly installed with a movable sleeve, and the movable sleeve is slidably sleeved on the outer side of the limiting rod. One side of the front of the movable sleeve is fixedly installed with a fixing plate, and the fixing plate and the support plate are perpendicular to each other. The top side of the fixing plate is fixedly installed with a vertical plate. One end of the front of the fixing plate is fixedly installed with a lower plate frame, and the top of the vertical plate is fixedly installed with an upper plate frame. A number of jacks are correspondingly opened inside the lower plate frame and the upper plate frame. A silicone oil box is arranged at the top of the base and directly below the lower plate frame.

[0006] As an optimization, a servo motor is provided at the bottom of the base, and the bottom end of the screw rod is in transmission connection with the output shaft of the servo motor. The electric heating tube is reversely inserted into the jack. By starting the servo motor, the screw rod will be driven to rotate inside the threaded sleeve, and then the movable sleeves on both sides will be driven to slide along the outer wall of the limiting rod. Therefore, the lower plate frame and the upper plate frame will be driven to lift, so that the port of the electric heating tube can be immersed in the silicone oil box, thus facilitating the filling of silicone oil into the electric heating tube.

[0007] As an optimization, four groups of slots are arrayed and opened on the outside of the lower plate frame corresponding to each jack, and positioning wheel assemblies are arranged in the slots.

[0008] As an optimization, the positioning wheel assembly includes a rotating rod rotatably connected in the slot. A rotating wheel is fixedly installed in the middle of the rotating rod, and a leather sleeve is sleeved outside the rotating wheel.

[0009] As an optimization, the material of the leather sleeve is rubber. A number of convex strips are arrayed and installed on the outside of the leather sleeve. When the electric heating tube is reversely inserted into the jack, the leather sleeve will contact the outer wall of the electric heating tube, and then the leather sleeve will deform and squeeze the electric heating tube to position it, and will rotate as the electric heating tube continues to be inserted downward until the port of the electric heating tube is immersed in the silicone oil box. At the same time, the convex strips can increase the friction force between the leather sleeve and the outer wall of the electric heating tube, improving the positioning effect.

[0010] As an optimization, a number of filling column assemblies are arranged at the positions corresponding to the jacks inside the silicone oil box. The filling column assembly includes a fixed column fixedly installed on the inner wall of the silicone oil box. A threaded hole is opened at the center inside the fixed column, and a threaded column is threadedly inserted into the threaded hole. A turntable is fixedly installed at the top of the threaded column, and a piston block is fixedly installed on the top side of the threaded column.

[0011] As an optimization, the turntable is threadedly fixed on the fixed column through the threaded column. The outer diameter of the piston block is the same as the inner diameter of the electric heating tube. The piston block is embedded in the pipe orifice of the electric heating tube. The piston block can fully push the silicone oil into the pipe orifice of the electric heating tube, so that the pipe orifice can be in full contact with the silicone oil. By turning the turntable, the threaded column will be driven to rotate inside the threaded hole, and then the height of the piston block can be finely adjusted, so as to be applicable to electric heating tubes with different pipe orifice gaps.

[0012] The beneficial effects of the present utility model are:

[0013] 1. The silicone oil filling device for the electric heating tube can position the electric heating tube by the extrusion deformation of the four sets of leather sleeves arranged around the jack when the electric heating tube is inserted upside down. Then, when the screw rotates in the threaded sleeve, it will drive the lower plate frame and the upper plate frame to lift through the movable sleeve, so that the tube orifice of the electric heating tube inserted upside down in the jack can be immersed downward into the silicone oil in the silicone oil box, thus enabling the filling of silicone oil for multiple electric heating tubes at one time, effectively reducing manual labor and facilitating mass production.

[0014] 2. In the silicone oil filling device for the electric heating tube, when the electric heating tube is immersed downward into the silicone oil, the piston block will be inserted into the tube orifice of the electric heating tube, and then the silicone oil will be squeezed into the tube orifice of the electric heating tube, so that the silicone oil can be in full contact with the tube orifice. By rotating the turntable, the height of the piston block can be finely adjusted, so that it can be applicable to electric heating tubes with different tube orifice gaps. Then, the electric heating tube is suspended by moving the lower plate frame and the upper plate frame upward, and after a certain period of time, the silicone oil on the outer surface of the electric heating tube is drained, so as to fully ensure the silicone oil filling effect of all the electric heating tubes in the batch and reduce environmental pollution.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figure 1-2, An electric heating tube silicone oil filling device, including a base 1. Two limiting rods 2 are fixedly installed near the corners on the top side of the base 1. The top of the limiting rods 2 is fixedly installed with a top plate 3. A screw rod 4 is rotatably connected in the middle of the two limiting rods 2 on the top of the base 1, and the top of the screw rod 4 is rotatably connected to the middle of the top plate 3. A servo motor is arranged at the bottom of the base 1, and the bottom end of the screw rod 4 is in transmission connection with the output shaft of the servo motor. A threaded sleeve 5 is sleeved on the outer side of the screw rod 4. Support plates 6 are fixedly installed on both sides of the threaded sleeve 5. The end of the support plate 6 is fixedly installed with a movable sleeve 7, and the movable sleeve 7 is slidably sleeved on the outer side of the limiting rod 2. A fixing plate 8 is fixedly installed on one side of the front of the movable sleeve 7, and the fixing plate 8 and the support plate 6 are perpendicular to each other. A vertical plate 9 is fixedly installed on the top side of the fixing plate 8. A lower plate frame 10 is fixedly installed at one end of the front of the fixing plate 8. An upper plate frame 11 is fixedly installed at the top end of the vertical plate 9. A number of jacks 12 are correspondingly opened inside the lower plate frame 10 and the upper plate frame 11. The electric heating tube is reversely inserted into the jacks 12. A silicone oil box 13 is arranged on the top of the base 1 and directly below the lower plate frame 10. By starting the servo motor, it will drive the screw rod 4 to rotate inside the threaded sleeve 5, and then drive the two movable sleeves 7 to slide along the outer wall of the limiting rod 2, so as to drive the lower plate frame 10 and the upper plate frame 11 to rise and fall, so that the port of the electric heating tube can be immersed in the silicone oil box 13, thus facilitating the filling of silicone oil into the electric heating tube.

[0022] Please refer to Figure 3 , Four groups of notches are arranged in an array on the outer side of each jack 12 corresponding to the lower plate frame 10, and a positioning wheel assembly is arranged in the notches. The positioning wheel assembly includes a rotating rod 14 rotatably connected in the notches. A rotating wheel 15 is fixedly installed in the middle of the rotating rod 14. A leather sleeve 16 is sleeved on the outer side of the rotating wheel 15. The material of the leather sleeve 16 is rubber. A number of convex strips 17 are arranged in an array on the outer side of the leather sleeve 16. When the electric heating tube is reversely inserted into the jack 12, the leather sleeve 16 will contact the outer wall of the electric heating tube, and then the leather sleeve 16 will deform and squeeze the electric heating tube to position it, and will rotate as the electric heating tube continues to be inserted downward until the port of the electric heating tube is immersed in the silicone oil box 13. At the same time, the convex strips 17 can increase the friction force between the leather sleeve 16 and the outer wall of the electric heating tube and improve the positioning effect;

[0023] Please refer to Figure 4, several filling column components are arranged inside the silicone oil box 13 corresponding to the position of the jack 12. The filling column component includes a fixed column 18 fixedly installed on the inner wall of the silicone oil box 13. A threaded hole 19 is opened at the center of the inside of the fixed column 18. A threaded column 20 is threadedly inserted into the threaded hole 19. A turntable 21 is fixedly installed at the top of the threaded column 20. The turntable 21 is threadedly fixed on the fixed column 18 through the threaded column 20. A piston block 22 is fixedly installed on the top side of the threaded column 20. The outer diameter of the piston block 22 is the same as the inner diameter of the electric heating tube. The piston block 22 is embedded in the pipe orifice of the electric heating tube. Through the piston block 22, the silicone oil can be fully pushed into the pipe orifice of the electric heating tube, so that the pipe orifice can be in full contact with the silicone oil. By turning the turntable 21, the threaded column 20 will be driven to rotate inside the threaded hole 19, and then the height of the piston block 22 can be finely adjusted, so as to be applicable to electric heating tubes with different pipe orifice gaps.

[0024] During use, first, the electric heating tube is inserted into the jack 12 in an inverted manner. When inserting it into the jack 12 of the lower plate frame 10 below, the four leather sleeves 16 around it will be squeezed and deformed to closely adhere to the outside of the electric heating tube. Then, it will play a positioning role for the electric heating tube and will rotate as the electric heating tube continues to be inserted downward until the port of the electric heating tube protrudes a certain distance away from the lower plate frame 10.

[0025] After that, by starting the motor to drive the screw rod 4 to rotate counterclockwise inside the threaded sleeve 5, the movable sleeve 7 will be driven to slide downward along the outer wall of the limiting rod 2. Then, the lower plate frame 10 and the upper plate frame 11 will be driven to move downward synchronously. Then, the electric heating tube inserted into the jack 12 will be inserted downward into the silicone oil box 13, so that the pipe orifice is submerged in the silicone oil.

[0026] At the same time, the pipe orifice of the electric heating tube will be sleeved outside the piston block 22 downward, so that the piston block 22 squeezes the silicone oil into the pipe orifice of the electric heating tube. Then, the silicone oil can be in full contact with the pipe orifice. By turning the turntable 21, the threaded column 20 will be driven to rotate in the threaded hole 19, and then the height of the piston block 22 can be finely adjusted to be applicable to electric heating tubes with different pipe orifice gaps.

[0027] Finally, by driving the screw rod 4 to rotate clockwise by the motor, the electric heating tube will be driven to move upward. So, the electric heating tube will be suspended above the silicone oil box 13. After the silicone oil on the surface of the electric heating tube has drained, it can be taken out for the next process.

[0028] In summary, for the silicone oil filling device of the electric heating tube, through the four groups of leather sleeves 16 arranged around the jack 12, when the electric heating tube is inserted upside down, the leather sleeve 16 can be squeezed and deformed to position the electric heating tube. Then, by rotating the screw 4 in the threaded sleeve 5, the lower plate frame 10 and the upper plate frame 11 can be driven by the movable sleeve 7 to move up and down. Furthermore, the tube orifice of the electric heating tube inserted upside down in the jack 12 can be immersed downward into the silicone oil in the silicone oil box 13, so that multiple electric heating tubes can be filled with silicone oil at one time, effectively reducing the labor and facilitating mass production.

[0029] When the electric heating tube is immersed downward into the silicone oil, the piston block 22 will be inserted into the tube orifice of the electric heating tube, and then the silicone oil will be squeezed into the tube orifice of the electric heating tube. Therefore, the silicone oil can be in full contact with the tube orifice. By rotating the turntable 21, the height of the piston block 22 can be finely adjusted, so that it can be applied to electric heating tubes with different tube orifice gaps. Then, by moving up the lower plate frame 10 and the upper plate frame 11 to suspend the electric heating tube, the silicone oil on the outer surface of the electric heating tube can be drained after a certain period of time, thus fully ensuring the silicone oil filling effect of all the electric heating tubes in the batch and reducing environmental pollution.
