The support platform 120 is used to support and move the core rod and hardware. The positioning mechanism 130 is used to move against the hardware to be socketed during the socketing operation. The support platform 120 and the positioning mechanism 130 cooperate to socket the hardware onto the end of the core rod. The crimping machine 110 is used to crimp the hardware socketed onto the core rod to obtain an insulator preform. The injection system is used to perform injection molding on the insulator preform at the injection station, injection-molding sheds around the outer periphery of the core rod to obtain the insulator product. The coating station and stripping station are located upstream of the crimping station, and the injection station is located downstream of the crimping station.

[0029] The production line 10 in this application is mainly used to produce insulator products. The production line 10 can adjust some parameters according to actual production requirements, such as the length of the insulator product, the cross-sectional specifications of the core rod, the crimping position of the hardware, the structure of the umbrella skirt, etc.

[0030] The production line 10 further includes a conveyor mechanism 20 for moving core rods, hardware, insulator preforms, or insulator products between workstations. The conveyor mechanism 20 can be an automated device such as a robotic arm, providing flexible placement and high flow efficiency.

[0031] like Figure 2 As shown, the coating system 200 includes a core rod coating device 400, and the core rod coating device 400 includes a core rod coating mechanism 410, a core rod loading mechanism 420 and a core rod drying mechanism 430. The core rod loading mechanism 420 is used to load the core rod; the core rod coating mechanism 410 is arranged on the core rod loading mechanism 420, and is used to coat the outer surface of the core rod after loading; the core rod drying mechanism 430 is arranged on the core rod loading mechanism 420, and is used to dry the core rod after coating.

[0032] The mandrel loading mechanism 420 includes a mandrel moving assembly 421, a mandrel loading rack 422, and a mandrel lifting assembly 423. The mandrel moving assembly 421 is used to move the mandrel; the mandrel loading rack 422 is arranged on one side of the mandrel moving assembly 421, and is used to place the mandrel; the mandrel lifting assembly 423 is arranged at the bottom of one end of the mandrel loading rack 422 close to the mandrel moving assembly 421, and can partially extend out of the upper surface of the mandrel loading rack 422, and is used to lift the mandrel onto the mandrel moving assembly 421.

[0033] The core rod moving assembly 421 includes a conveying platform 4211, a conveying guide rail 4212, a conveying drive 4213, a conveying assembly (not shown), and a conveying seat 4214.

[0034] The core rod loading rack 422 includes a fixed plate 4221, a loading plate 4222 and a stopper 4223. The two fixed plates 4221 are arranged relative to each other in the vertical direction on the conveying platform 4211. The loading plate 4222 is mounted in the middle of the two fixed plates 4221, and the loading plate 4222 is tilted downward toward the core rod moving assembly 421. The end of the loading plate 4222 with a higher horizontal height is defined as the loading port, and the other end is the discharge port. The tilted loading plate 4222 facilitates the core rod to move quickly from the loading port to the discharge port, thereby improving the loading efficiency; a number of stoppers 4223 are spaced apart at the end of the loading plate 4222 with a lower horizontal height to prevent the core rod from falling.

[0035] The core rod lifting assembly 423 includes a connected lifting cylinder and a lifting plate (not shown in the figure). A hollow area corresponding to the lifting plate is provided at the discharge port of the loading plate 4222. The lifting cylinder can drive the lifting plate to move upward in the vertical direction and pass through the hollow area. The maximum moving height of the lifting plate is higher than the height of the stopper 4223, so as to lift the core rod close to the stopper 4223 on the loading plate 4222 to the top of the stopper 4223, so as to facilitate the movement of the core rod to the conveying seat 4214 of the core rod moving assembly 421.

[0036] Furthermore, the mandrel feeding mechanism 420 further includes an auxiliary lifting assembly 424 for guiding the mandrel lifted by the mandrel lifting assembly 423 to the mandrel moving assembly 421. The auxiliary lifting assembly 424 includes an auxiliary moving assembly 4241, an auxiliary fixing plate 4242, a guide rod 4243 and a guide plate 4244. The two guide rods 4243 are arranged horizontally and parallel to each other. The guide rods 4243 are mounted on the upper parts of the two fixing plates 4221 and are respectively located near the feeding port and the discharging port; the auxiliary fixing plate 4242 is arranged vertically and penetrates the two guide rods 4243, so that the auxiliary fixing plate 424 2 can move along the guide rod 4243; the guide plate 4244 is arranged on the auxiliary fixing plate 4242 at one end close to the mandrel moving assembly 421, the plate surface of the guide plate 4244 is inclined downward toward the mandrel moving assembly 421, and the plate surface height of the guide plate 4244 is higher than the stopper 4223 and the conveying seat 4214; the auxiliary moving assembly 4241 is arranged on one of the fixing plates 4221, and can drive the auxiliary fixing plate 4242 to move along the guide rod 4243 to adjust the position of the guide plate 4244, so that it can play a limiting role for mandrels of more length specifications, thereby expanding the application range of the equipment.

[0037] Combine Figure 3As shown, the mandrel coating mechanism 410 is arranged on the mandrel moving assembly 421 and is located above the middle of the mandrel moving path. The mandrel coating mechanism 410 includes a coating frame 411 and an operating assembly 412. The coating frame 411 includes a plurality of support rods 4111 and a top plate 4112. The plurality of support rods 4111 are vertically arranged on the conveying platform 4211 and distributed on both sides of the conveying guide rail 4212; the top plate 4112 is horizontally mounted on the plurality of support rods 4111 so that the top plate 4112 is located above the conveying guide rail 4212, that is, above the mandrel moving path; the operating assembly 412 is arranged at the bottom of the top plate 4112 and is used to perform coating operations on the outer surface of the mandrel. The operating assembly 412 includes a claw driving member (Figure The top plate 4112 includes two grippers 4121 and a water absorbent element (not shown). The gripper drive element is disposed at the bottom of the top plate 4112. The two grippers 4121 are spaced apart from each other and connected to the gripper drive element. The gripper drive element drives the two grippers 4121 to move toward each other to clamp the mandrel. The water absorbent element is disposed on the inner side of the two grippers 4121, adjacent to each other, and is used to absorb the mandrel coating agent. As the grippers 4121 grip the mandrel, the water absorbent element squeezes the mandrel to release the mandrel coating agent. Once the grippers 4121 have secured the mandrel, the mandrel moving assembly 421 is used to control the mandrel's movement along the conveyor rail 4212, thereby coating the mandrel's outer surface with the mandrel coating agent squeezed out of the water absorbent element. The water absorbent element can be a sponge or other product, and the mandrel coating agent can be a coupling agent or other product.

[0038] Furthermore, the operating component 412 also includes a first raw material conveying component 4122, which is used to continuously provide raw materials to the water-absorbing component. The first raw material conveying component 4122 includes a raw material barrel, a pipeline and a peristaltic pump. The water-absorbing component is connected to the raw material barrel through a pipeline. The peristaltic pump can drive the pipeline to absorb raw materials from the raw material barrel and continuously convey them to the water-absorbing component, ensuring that the water-absorbing component is always filled with sufficient core rod coating agent to ensure the coating effect. There is no need to replace the water-absorbing component during the production process, making the production rhythm more compact and more efficient.

[0039] Furthermore, to avoid wasting resources, the mandrel coating mechanism 410 further includes a reflux assembly 413 for collecting mandrel coating agent dripping during the coating operation or collecting cleaning agent dripping during the cleaning operation. The reflux assembly 413 includes a first reflux tray 4131 and a second reflux tray 4132.

In addition, the reflux assembly 413 may include a reflux drive 4133, which is arranged on one side of the conveying platform 4211 and connected to the first reflux disk 4131, and is used to drive the first reflux disk 4131 away from the core rod coating mechanism 410 in a direction perpendicular to the core rod moving direction. When the claw 4121 needs to be replaced or the first reflux disk 4131 needs to be disassembled and cleaned, the first reflux disk 4131 can be controlled to move away for easy assembly; the second reflux disk 4132 is detachably connected to the conveying seat 4214 and the conveying support for easy assembly.

[0040] Furthermore, the reflux assembly 413 also includes two auxiliary reflux trays 4134, which are respectively arranged on both sides of the conveying guide rail 4212, and are used to collect liquid that drips during the coating operation or cleaning operation on the core rod and is not collected by the first reflux tray 4131 and the second reflux tray 4132, so as to prevent it from dripping directly onto the conveying platform 4211 and polluting the operating environment.

[0041] The mandrel drying mechanism 430 is disposed on the mandrel moving assembly 421, and the mandrel drying mechanism 430 and the mandrel loading rack 422 are respectively located on either side of the mandrel coating mechanism 410. This allows the mandrels to be loaded from the mandrel loading rack 422 onto the mandrel moving assembly 421, and after passing through the mandrel coating mechanism 410 to complete the coating operation, they are moved to the mandrel drying mechanism 430 for drying. This facilitates the sequential flow of mandrels for loading, coating, and drying operations, thereby improving production efficiency. The mandrel drying mechanism 430 includes a drying rack and a fan. The drying rack is disposed on one side of the conveying platform 4211, and the fan is disposed above the drying rack, with the fan's air outlet facing the mandrel moving assembly 421, thereby improving the drying efficiency of the mandrels.

The loading tray 514 is provided with several hardware slots for placing hardware. The shape of the hardware slots matches the outer surface contour of the hardware to ensure that the hardware is firmly placed. A loading button 515 is provided at one end of the loading platform 511 for starting the hardware loading mechanism; a loading buffer 516 is provided at the other end of the loading platform 511 for limiting the maximum moving distance of the loading tray 514. By clicking the loading button 515, the loading tray 514 can be controlled to move along the loading guide rail 512 until the loading tray 514 abuts against the loading buffer 516 and stops moving. The entire loading process is simple and convenient to operate.

[0044] The fitting coating mechanism is arranged on the loading platform 511 and is located on one side of the loading buffer 516, so as to facilitate the coating operation of the fittings that have completed the loading operation, shorten the circulation distance, and improve production efficiency. The fitting coating mechanism can be an infiltration tank, in which a fitting coating agent is placed. The conveying mechanism 20 is used to clamp the fittings and infiltrate them in the infiltration tank, so that the fitting coating agent adheres to the inner surface of the fittings to complete the coating operation of the fittings. The fitting coating agent can be a coupling agent or other reagent. The fitting coating mechanism also includes a second raw material conveying component (not shown), whose structure and function are similar to those of the first raw material conveying component 4122 and will not be repeated here.

[0045] The hardware drying mechanism is arranged on the loading platform 511 and is located on one side of the hardware coating mechanism, so as to facilitate drying the hardware after coating, shorten the circulation distance and improve production efficiency.

[0072] Combine Figure 11 As shown, the insulator production line 10 further includes a preheating system 600 for heating the product to be preheated at a preheating station located between the crimping station and the injection station. The product to be preheated is described below using an insulator preform as an example.

[0073] The preheating system 600 includes a preheating rack 610, a preheating conveyor assembly 620 and an oven 630. The preheating conveyor assembly 620 is set on the preheating rack 610 and is used to control the movement of the insulator preforms to be preheated into the oven 630 and control the movement of the preheated insulator preforms out of the oven 630. The oven 610 is set in the middle of the preheating conveyor assembly 620 and is used to heat the insulator preforms.

[0074] The preheating conveying assembly 620 includes two movable racks 621, which are arranged in parallel at intervals on the preheating rack 610 for cooperating in carrying the insulator preform and controlling the movement of the insulator preform. A transfer button is provided on the preheating conveying assembly 620 for controlling the movement of the movable rack 621. Several bearing positions are evenly spaced along the moving direction of the preheating conveying assembly 620, that is, a plurality of bearing seats 622 are correspondingly provided on the two movable racks 621, and every two corresponding bearing seats 622 on the two movable racks 621 form a bearing position, wherein several bearing positions are provided in the heating area of the oven 630, and a bearing position is provided on each side outside the heating area. The bearing position outside the heating area and closest to the crimping system 100 is defined as the loading bearing position, and the bearing position outside the heating area and farthest from the crimping system 100 is defined as the unloading bearing position. When the core rod and the hardware are crimped to form the insulator preform, the conveying mechanism 20 can be The insulator preform is transported to the loading load position and the transfer button is activated. The preheating conveying component 620 moves forward a preset distance along its moving direction so that the loading load position enters the first load position in the heating area. The next insulator preform is then transported to the loading load position and the transfer button is activated until all load positions in the heating area are filled with insulator preforms. When the insulator preform at the last load position in the heating area completes the heating operation, the transfer button is activated to move it forward to the unloading load position. The conveying mechanism 20 can then transport the insulator preform at this position to the injection system. The above operations are repeated in sequence, thereby realizing the assembly line operation of the insulator preform heating operation.

[0075] Furthermore, the preheating conveying assembly 620 also includes a preheating drive component for controlling at least one movable frame 621 to move in a direction perpendicular to its moving direction to adjust the distance between the two movable frames 621, and then adjust the distance between the corresponding supporting seats 622 to carry insulator preforms of more length specifications, thereby improving the versatility of the equipment.

[0076] Furthermore, the preheating conveyor assembly 620 is also equipped with a sensor for detecting whether an insulator preform is placed at the loading position. If no insulator preform is placed, a prompt is given to continue placing the insulator preform. Alternatively, a sensor is provided for detecting whether an insulator preform at the unloading position has been removed by the conveyor mechanism 20. If so, the preheating conveyor assembly 620 is controlled to advance one position to replenish the insulator preform. The distance and rhythm of movement of the preheating conveyor assembly 620 can be adjusted according to heating requirements and are not specifically limited here.

[0077] The oven 630 is a heating device with openings at both ends. These openings allow the preheating conveyor assembly 620 to move through the oven 630. Furthermore, lift doors can be provided at the openings at both ends of the oven 630 to close the openings when the insulator preforms within the oven 630 are being heated and the preheating conveyor assembly 620 does not need to move, thereby reducing heat loss and improving heating efficiency. The oven 630 can be implemented using existing technology and is not specifically limited herein.

[0078] Furthermore, preheating system 600 also includes a temperature detection assembly 640, mounted on preheating frame 610 at the unloading position. This assembly is used to detect whether the surface temperature of the heated insulator preform meets the requirements for subsequent injection molding, thereby ensuring injection quality. Temperature detection assembly 640 can be implemented using existing technology, as long as it can achieve the corresponding function, and is not specifically limited here.

[0079] The injection system includes an injection molding machine and a feeder rack. The injection molding machine is used to inject insulator preforms. The feeder rack is located at the injection molding machine's feed port and is used to place and move the insulator preforms. A conveyor mechanism 20 moves the heated insulator preforms onto the feeder rack. The feeder rack controls the movement of the insulator preforms into the injection mold within the injection molding machine and secures them in place. The injection molding machine then injects the insulator preforms, injecting high-temperature vulcanized silicone rubber molded sheds around the core rod of the insulator preform. This creates a sealed connection between the core rod, hardware, and sheds, resulting in the final insulator product. The injection molding system can be implemented using existing technologies and is not specifically limited here.
