Technical Field
[0001] This utility model belongs to the technical field of equipment for automated mechanical cleaning, specifically a cylinder-driven end cap residual adhesive cleaning device. Background Technology
[0002] Insulating tie rods, as key components in ultra-high voltage gas-insulated metal-enclosed circuit breakers, function to control power system load and protect power system safety. Their production process requires first loading the insulating fabric blank into a tube mold, then placing it in an oven for vacuum impregnation and curing under specific conditions. Existing tube molds consist of a mandrel, an outer mold, and two end caps. Negative pressure within the mold draws the adhesive into the tube mold through the adhesive openings on the end caps. However, during reuse, cured adhesive residue remains in the adhesive openings of the end caps, requiring manual removal using hammers and ejectors. This method is inefficient and poses risks of safety issues and damage to the end caps. Current automated adhesive residue cleaning devices suffer from insufficient cylinder power, slow response speed, mismatch between the ejector rod and the adhesive opening, inaccurate alignment, complex and bulky equipment structure, and incompatibility with production conditions. Therefore, designing an efficient, compact, and easy-to-operate and maintain end cap adhesive residue cleaning device is of great significance. Utility Model Content

Detailed Implementation
[0032] The present invention will now be described in further detail with reference to the accompanying drawings:
[0033] This utility model discloses a cylinder-driven end cap residual adhesive cleaning device, including an end cap 1, a clamping assembly 2, a push rod 3, an upper housing 4, a residual adhesive removal cylinder 5, an exhaust throttle valve 6, an end cap positioning cylinder 7, a main frame 8, a sealing plate 9, a lower housing 10, a solenoid valve I 12, a solenoid valve II 13, and a collection box 11. The end cap 1 is detachably fixed to the clamping assembly 2. The sealing plate 9 and the upper housing 4 are fixed to the upper end of the main frame 8, and the lower housing 10 is fixed around the lower end of the main frame 8. The push rod 3 is connected to the residual adhesive removal cylinder. At one end of the sealing plate 9, clamping assembly 2, top residual glue cylinder 5 and end cap positioning cylinder 7 are fixed respectively. Each of the top residual glue cylinder 5 and end cap positioning cylinder 7 is fixed with an exhaust throttle valve 6. Solenoid valve I 12 and solenoid valve II 13 are fixed inside the lower housing 10. The collection box 11 is fixed on one side of the main frame 8. When solenoid valve I 12 is activated, the end cap positioning cylinder 7 is activated to achieve precise alignment between the top rod 3 and the end cap 1. Then, solenoid valve II 13 is activated to drive the top residual glue cylinder 5 to push the top rod 3 out of the residual glue in the end cap 1.
[0034] Specifically, the end cap 1 includes a rubber inlet 17 and a flange 18, which are integrally formed.
[0035] Specifically, the nozzle 17 is provided with an inner conical surface 16, the tolerance of the inner conical surface 16 is H7 grade: 0~+0.018mm, and the length of the nozzle 17 is 60mm~75mm.
[0036] Specifically, the top rod 3 has an outer conical surface at its end, with a tolerance of h6 grade: -0.013mm to 0mm.
[0037] Specifically, the end of the push rod 3 is provided with an M12×1.75 external thread, which matches and screws into the internal thread at the end of the piston rod of the top residual glue cylinder 5, with a preload torque of 45~50 N·m.
[0038] Specifically, the flange 18 has a diameter of ø120mm~ø200mm.
[0039] Specifically, the clamping assembly 2 includes a front fixing plate 19, a rear fixing plate 20, a reinforcing plate 21, a base plate 22, and a sensor 23. The front fixing plate 19 and the rear fixing plate 20 are placed on both sides of the end cover 1 and fixed to the end cover 1 with bolts. The reinforcing plate 21 is welded to both sides of the front fixing plate 19. The lower end faces of the front fixing plate 19, the rear fixing plate 20, and the reinforcing plate 21 are all vertically welded to the base plate 22. The sensor 23 is installed on the front fixing plate, and the base plate 22 is fixed on the sealing plate 9. After the sensor senses that the end cover 1 has been placed, it automatically completes the positioning and cleans the residual adhesive.
[0040] More preferably, the main frame 8, the upper shell 4, the lower shell 10 and the collection box 11 are all made of stainless steel, and the main frame 8 adopts a box-type frame structure.
[0041] Specifically, the sealing plate 9 is made of 3mm silicone sheet.
[0042] Even better, the top residual glue cylinder 5 and the end cap positioning cylinder 7 are controlled by a PLC.
[0043] As attached Figure 1 ~Appendix Figure 3 As shown, the end cap 1 is first placed in the clamping assembly 2 and fixed. The residual adhesive removal cylinder 5 uses a large-diameter cylinder, and the air nozzle uses a fast exhaust throttle valve 6, which makes the residual adhesive removal cylinder 5 respond faster. The end cap positioning cylinder 7 firmly clamps the end cap 1, ensuring that the center of the glue outlet 17 and the center of the push rod 3 are on the same horizontal line. The power is turned on, and the residual adhesive removal cylinder 5 compresses air, quickly pushing the push rod 3 out. Since the glue outlet 17 has a conical structure, it ensures that the end cap 1 can perfectly match the push rod 3, and the residual adhesive in the glue outlet 17 of the end cap 1 is quickly pushed out to the residual adhesive collection box 11. Then the gas in the cylinder is discharged through the exhaust throttle valve 6, the push rod 3 exits the glue outlet 17, and then the end cap 1 is taken out. After placing the next end cap 1, the work is repeated. The time for cleaning residual adhesive from each end cap 1 is 10 seconds. This device is suitable for end caps 1 with flange outer diameters between φ120mm and φ200mm. Workers only need to load and unload materials. Once the sensor detects that material has been put in, the end cap 1 is automatically positioned. The entire process of this device is completed by a cylinder. It has a simple structure, is easy to maintain, and reduces the workload of workers.
[0044] As attached Figure 6 As shown, the equipment installation is as follows: Place the residual adhesive removal device on the end cap in a suitable working position, ensuring that the device is placed stably. The overall dimensions of this end cap residual adhesive removal device are length × width × height: 800mm × 300mm × 800mm. Due to its compact structure and small footprint, the installation location can be flexibly selected according to actual work needs.
[0045] Cylinder Adjustment: Check the installation of the top residual adhesive cylinder 5 to ensure it is securely installed. Connect the air circuit and adjust the intake and exhaust speeds of the top residual adhesive cylinder 5 using the quick exhaust throttle valve 6. Adjust the force and response speed of the top residual adhesive cylinder 5 to achieve optimal working condition.
[0046] As attached Figure 4 As shown, centering of the nozzle 17: Place the end cap 1 in the designated position, adjust the position of the nozzle 17, and use the conical centering structure of the nozzle 17 to accurately center the push rod 3 with the nozzle 17. During the centering process, calibration can be performed by observation or using auxiliary tools to ensure centering accuracy.
[0047] As attached Figure 5As shown, residual adhesive treatment: Upon power activation, the residual adhesive ejector cylinder 5 actuates rapidly under the action of the exhaust throttle valve 6, utilizing the powerful force generated by the large-diameter cylinder to eject the residual adhesive from the end cap 1. The residual adhesive then falls into the collection box 11 under gravity. During the treatment process, the operating parameters of the residual adhesive ejector cylinder 5 can be adjusted appropriately based on factors such as the material of the end cap 1, the type and thickness of the residual adhesive, etc., to achieve the best residual adhesive treatment effect.
[0048] Residual adhesive removal: Regularly remove residual adhesive from collection box 11 to ensure that there is sufficient space in collection box 11 to continue collecting residual adhesive. When removing residual adhesive, choose an appropriate removal method according to the nature of the residual adhesive, such as physical removal or chemical removal.
[0049] Working principle: By using a cylinder to move rapidly under the action of a quick exhaust valve, and utilizing the conical centering structure of the glue port 17, the push rod 3 is accurately aligned with the glue port 17. The powerful force generated by the large-diameter residual glue-removing cylinder 5 pushes the residual glue on the end cap out.
[0050] The pneumatic actuation timing analysis is as follows:
[0051] Initial state: The exhaust throttle valve 6 is adjusted to exhaust the rodless chamber of the top residual glue cylinder 5, and the push rod 3 retracts to its original position, i.e., 5mm away from the glue outlet;
[0052] Ejection stage: Solenoid valve 13 is energized, compressed air enters the rod chamber, and ejector rod 3 impacts the residual adhesive at a speed of 0.5m / s;
[0053] Pressure holding stage: The system maintains a pressure of 0.6 MPa for 0.2 to 0.5 seconds, and the front end of the push rod 3 completely penetrates the conical surface of the glue nozzle;
[0054] Reset phase: Solenoid valve 13 reverses direction, air enters the rodless chamber, and push rod 3 slowly retracts under the control of exhaust throttle valve 6.
