Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of sealing strip processing, and specifically to a microwave vulcanization device for preventing deviation of sealing strips. Background Technology

[0002] In the microwave vulcanization production of sealing strips, the stability of the equipment directly determines the dimensional accuracy and performance consistency of the product. Traditional microwave vulcanization devices for sealing strips generally suffer from two major technical shortcomings: firstly, they lack an effective anti-deviation mechanism; secondly, they cannot achieve rapid cooling of the internal space of the vulcanization chamber, which severely restricts production efficiency and product quality.

[0003] During the conveying process, sealing strips are prone to lateral deviation due to factors such as material flexibility, uneven stress, or conveyor belt vibration. Once they deviate from the preset vulcanization path, it can lead to localized overheating or underheating, resulting in defects such as deformation of the sealing strip cross-section and uneven foaming, and may even cause material jamming and shutdown, increasing the scrap rate. Although existing devices are equipped with simple guide wheels, they have poor adaptability to sealing strips of different specifications and cannot dynamically correct deviations, thus having limited effectiveness in preventing deviation.

[0004] Meanwhile, after microwave vulcanization, the vulcanization chamber needs to be rapidly cooled to prevent the sealing strip from continuously aging due to heat. Traditional devices mostly rely on natural cooling or a single fan for heat dissipation, resulting in slow cooling speeds. This not only prolongs the production cycle but also causes uneven temperature distribution within the chamber, leading to varying cooling effects on the sealing strips at different locations and affecting product performance stability. For batch continuous production, this problem of insufficient cooling efficiency is even more pronounced, severely reducing equipment capacity. Therefore, developing a microwave vulcanization device for sealing strips that combines anti-deviation functionality with rapid cooling capability has become an urgent need for industry upgrades. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a microwave vulcanizing device for preventing deviation of sealing strips, which solves the technical problem in the prior art that sealing strips are prone to lateral deviation during the conveying process due to factors such as material flexibility, uneven stress, or vibration of the conveyor belt.

[0006] According to one aspect, at least one embodiment of this disclosure provides a microwave vulcanization device for preventing deviation of a sealing strip, comprising: The device comprises a frame, a housing, and a magnetron, wherein the housing is fixed on the frame and the magnetron is disposed inside the housing; A switch-feed assembly is disposed on the housing and the platform; A cooling component, wherein the cooling component is disposed outside the housing; The switch feeding assembly includes a conveyor belt, which is installed in the frame. The frame surface is provided with a vertical frame, and both ends of the bottom of the vertical frame are rotatably connected to a rotating frame via a rotating shaft. Several straightening rods are vertically rotatably connected to the bottom of the rotating frame.

[0007] As a further technical solution, the top of the support frame is connected to a horizontal shaft via electric drive. Both ends of the horizontal shaft and the upper end of the rotating shaft of the rotating frame are equipped with transmission gears, which are bevel gears.

[0008] As a further technical solution, the side end face of the outer shell is rotatably connected to a flip-up door cover via a rotating shaft. The rotating shaft of the flip-up door cover is driven by electricity to rotate, and a pusher protrusion is provided at the lower end of the inner surface of the flip-up door cover.

[0009] As a further technical solution, the surface of the platform is provided with a discharge port, which is located inside the outer shell, and a sliding bottom cover that is electrically driven to flip inside the discharge port.

[0010] As a further technical solution, the cooling component includes several rectangular openings, all of which are located on the top of the outer shell. A telescopic cylinder is vertically mounted on one side of the outer shell, and a bracket is provided at the output end of the telescopic cylinder.

[0011] As a further technical solution, a heat dissipation fin frame is provided on one side of the bracket, and a number of heat conduction plates are provided on the bottom surface of the heat dissipation fin frame. The heat conduction plates are vertically fitted into the rectangular opening, and a number of fans are provided on one side of the heat dissipation fin frame.

[0012] As a further technical solution, the surface of the heat-conducting plate has a mesh-like perforated structure.

[0013] As a further technical solution, a discharge hopper is provided at the bottom of the platform, and the bottom of the discharge hopper has an inclined structure.

[0014] The beneficial effects of the embodiments disclosed herein are as follows: 1. In this disclosure, the switch-feed assembly solves the problem of sealing strip misalignment through dynamic correction design. The horizontal shaft and bevel gear drive enable synchronous adjustment of the rotating frames on both sides, and the correction rod flexibly conforms to sealing strips of different widths to prevent lateral deviation. The flip-up door cover and the pusher protrusion work in conjunction with the conveyor belt for precise feeding, while the sliding bottom cover controls the discharge rhythm. This structure ensures that the sealing strip always vulcanizes along a preset path, avoiding deformation and foaming defects caused by uneven local heating, reducing material jamming and downtime, improving finished product qualification rate and production continuity, and adapting to the needs of processing sealing strips of various specifications.

[0015] 2. In this disclosure, the cooling component solves the problems of slow cooling and uneven temperature distribution in traditional devices through a highly efficient heat dissipation design. A telescopic cylinder drives a heat-conducting plate into a rectangular opening, and the mesh structure enhances heat exchange; the heat dissipation fins expand the heat dissipation area, and a fan accelerates air convection to quickly dissipate heat. This structure allows for on-demand temperature control within the outer casing, preventing continuous heating and aging of the sealing strip, shortening the cooling cycle, ensuring consistent cooling performance of the sealing strip in different locations, improving product performance stability, adapting to continuous batch production, and increasing equipment capacity and processing efficiency.

[0024] like Figures 1-3 The illustration shows a microwave vulcanizing device for preventing deviation of a sealing strip according to an embodiment of the present disclosure, comprising: The assembly includes a frame 1, a housing 2, and a magnetron 3. The housing 2 is fixed on the frame 1, and the magnetron 3 is disposed inside the housing 2. A switch feeding assembly 4 is disposed on the housing 2 and the frame 1; Cooling component 5, wherein the cooling component 5 is disposed outside the housing 2; The switch feeding assembly 4 includes a conveyor belt 4-1, which is installed in the frame 1. A vertical frame 4-2 is provided on the surface of the frame 1. Both ends of the bottom of the vertical frame 4-2 are rotatably connected to a rotating frame 4-3 via a rotating shaft. Several straightening rods 4-4 are vertically rotatably connected to the bottom of the rotating frame 4-3. A horizontal shaft 4-5 is electrically driven to rotate horizontally at the top of the vertical frame 4-2. Transmission gears 4-6 are provided at both ends of the horizontal shaft 4-5 and at the upper end of the rotating shaft of the rotating frame 4-3. The transmission gears 4-6 are bevel gears. A flip-up door cover 4-7 is rotatably connected to the side end face of the outer shell 2 via a rotating shaft. The rotating shaft of the flip-up door cover 4-7 is electrically driven to rotate. A pusher protrusion 4-8 is provided at the lower end of the inner surface of the flip-up door cover 4-7. A discharge port 4-9 is opened on the surface of the frame 1. The discharge port 4-9 is located inside the outer shell 2. A sliding bottom cover 4-10 that is electrically driven to flip is provided inside the discharge port 4-9.

[0025] In some examples, precise feeding, positioning, and orderly discharge of the sealing strip are achieved by switching the feeding assembly 4. The conveyor belt 4-1 in the frame 1 smoothly transports the sealing strip to be processed to the inlet of the housing 2. The upright frame 4-2 on the surface of the frame 1 provides support for the straightening structure. The rotating frames 4-3 at both ends of its bottom are connected by a rotating shaft, and several vertically rotating straightening rods 4-4 at the bottom can clamp the two sides of the sealing strip. The electrically driven horizontal shaft 4-5 at the top of the upright frame 4-2 meshes with the bevel gears at the upper end of the rotating shaft of the rotating frame 4-3, forming a transmission structure. The flip-top door 4-7 on the side end of the housing 2 rotates via a rotating shaft and is electrically driven. The pushing protrusion 4-8 at the lower inner end assists in pushing the sealing strip. Inside the discharge port 4-9 on the surface of the frame 1, the electrically driven flip-top sliding bottom cover 4-10 receives the processed parts and guides their discharge.

[0026] During operation, the conveyor belt 4-1 transports the sealing strip to the straightening rod 4-4. The horizontal shaft 4-5 rotates, driving the rotating frame 4-3 to rotate via the bevel gear, ensuring the straightening rod 4-4 fits the sealing strip to prevent deviation. The flip-top cover 4-7 opens, and after the sealing strip enters the outer shell 2, the sliding bottom cover 4-10 closes to receive the workpiece. The magnetron 3 performs microwave vulcanization. After processing, the sliding bottom cover 4-10 flips, and the sealing strip is discharged through the outlet 4-9. The flip-top cover 4-7 operates synchronously to match the feeding rhythm. The bevel gear transmission ensures that the straightening rods 4-4 on both sides adjust synchronously to adapt to sealing strips of different widths. The pushing protrusion 4-8 and the conveyor belt 4-1 work together to ensure accurate feeding. The flip-top design of the sliding bottom cover 4-10 enables switching between processing position closure and discharge guidance, making the feeding, processing, and discharge processes continuous and efficient, avoiding deviation that could affect vulcanization quality.

[0027] like Figures 1-3As shown in the figure, the cooling component 5 in this embodiment includes several rectangular openings 5-1, all of which are opened on the top of the outer shell 2. A telescopic cylinder 5-2 is vertically mounted on one side of the outer shell 2. A bracket 5-3 is provided at the output end of the telescopic cylinder 5-2. A heat dissipation fin frame 5-4 is provided on one side of the bracket 5-3. Several heat conduction plates 5-5 are provided on the bottom surface of the heat dissipation fin frame 5-4. The heat conduction plates 5-5 are vertically fitted into the rectangular openings 5-1. Several fans 5-6 are provided on one side of the heat dissipation fin frame 5-4.

[0028] In some examples, the internal temperature of the outer casing 2 is effectively controlled by the cooling component 5, ensuring the stability of the microwave vulcanization process. Several rectangular openings 5-1 on the top of the outer casing 2 serve as heat dissipation channels. A telescopic cylinder 5-2, vertically mounted on one side, connects to a bracket 5-3 at its output end, which can raise and lower the heat dissipation fin frame 5-4. Several heat-conducting plates 5-5 on its bottom surface can be vertically inserted into the rectangular openings 5-1. Several fans 5-6 on one side of the heat dissipation fin frame 5-4 accelerate airflow and enhance heat dissipation.

[0029] During operation, as the temperature inside the outer casing 2 rises, the telescopic cylinder 5-2 drives the bracket 5-3 to descend, and the heat-conducting plate 5-5 inserts into the rectangular opening 5-1 to contact the high-temperature area. Heat is transferred to the heat dissipation fin holder 5-4 through metal heat conduction. The fan 5-6 starts blowing air through the fins, quickly dissipating the heat to the outside. When the temperature drops, the telescopic cylinder 5-2 drives the heat-conducting plate 5-5 to rise and disengage, preventing excessive cooling. The insertion and removal of the heat-conducting plate 5-5 and the rectangular opening 5-1 enables on-demand start and stop of heat dissipation, adapting to the temperature requirements of different vulcanization stages. The heat dissipation fin holder 5-4 increases the heat dissipation area, and the fan 5-6 enhances air convection, improving heat dissipation efficiency. The drive of the telescopic cylinder 5-2 automates and controls the cooling process, avoiding the lag of manual adjustment and ensuring that the temperature inside the outer casing 2 remains stable within the optimal vulcanization range, guaranteeing the processing quality of the sealing strip.

[0030] For example, such as Figure 1 As shown, the surface of the heat-conducting plate 5-5 has a mesh-like perforated structure.

[0031] In some examples, the mesh-like perforated structure on the surface of the heat-conducting plate 5-5 enhances airflow. When the heat-conducting plate 5-5 is inserted into the rectangular opening 5-1, the mesh allows hot air inside the outer casing 2 to flow upwards, forming convection with the heat dissipation fin holder 5-4 and accelerating heat dissipation. Simultaneously, the perforated structure reduces the weight of the heat-conducting plate 5-5, making the operation of the telescopic cylinder 5-2 less strenuous and reducing material usage. This improves the overall heat dissipation effect and operational flexibility of the cooling component 5 while ensuring thermal conductivity.

[0032] For example, such as Figure 3 As shown, the bottom of the platform 1 is provided with a discharge hopper 6, and the bottom of the discharge hopper 6 is an inclined structure.

[0033] In some examples, the discharge hopper 6 at the bottom of the frame 1 is located below the discharge port 4-9, and the inclined structure at the bottom guides the processed sealing strip to slide out. When the sliding bottom cover 4-10 flips over to discharge the sealing strip, the discharge hopper 6 can receive it and guide it to the designated collection area through the inclined surface, preventing the sealing strip from falling and scattering. This design ensures an orderly discharge process, reduces manual handling workload, and, together with the switch feed assembly 4, forms a complete feeding, processing, and discharge process, improving the automation efficiency of the device.

[0034] In actual use: Conveyor belt 4-1 transports the sealing strip to the inlet of housing 2. The top horizontal shaft 4-5 of the upright frame 4-2 rotates, driving the rotating frames 4-3 on both sides to rotate via bevel gear transmission, so that the straightening rod 4-4 fits against both sides of the sealing strip to prevent deviation. The electrically driven flip-top cover 4-7 opens, and after the sealing strip enters housing 2, the sliding bottom cover 4-10 closes to receive it. The magnetron 3 starts to perform microwave vulcanization. After vulcanization is completed, the sliding bottom cover 4-10 flips, and the sealing strip falls into the inclined discharge hopper 6 at the bottom through the discharge port 4-9 for discharge. The flip-top cover 4-7 moves synchronously to cooperate with the next cycle. During cooling, the telescopic cylinder 5-2 drives the bracket 5-3 to descend, the heat conduction plate 5-5 is inserted into the rectangular opening 5-1 to absorb heat, and the fan 5-6 blows the heat dissipation fin frame 5-4 to quickly dissipate heat. After the temperature is suitable, the heat conduction plate 5-5 rises, realizing anti-deviation conveying and precise temperature-controlled vulcanization throughout the process.
