Description

Technical Field

[0001] This invention relates to the field of insulating component manufacturing technology, specifically to an insulating component post-curing tunnel device. Background Technology

[0002] In recent years, with the State Grid Corporation of China raising its requirements for the electrical performance of insulation components used in switchgear, many insulation component manufacturers have added high-voltage grids to meet these requirements. This has led to an increase in the wall thickness of the insulation layer at the location of the high-voltage grid coil. While this design change has significantly improved electrical performance, the increased insulation layer, located at the junction of the outlet and the cylinder wall where the outlet wall is relatively thin, results in inconsistent shrinkage ratios. This leads to insufficient air circulation within conventional ovens, resulting in large temperature differences. Consequently, for products with thicker walls, post-curing at lower temperatures within the oven cannot be completed within the specified process time. Furthermore, the cooling time after post-curing is lengthy, leading to low oven utilization. If the oven door is opened for rapid cooling, products with significant wall thickness differences will experience uneven stress release due to the sudden temperature change, potentially causing cracking.

[0003] Among existing products, tunnel ovens utilize intermittent (cycled) conveying methods to transport materials. Heat exchange, drying, and curing occur within heated zones. Compared to traditional box ovens, continuous drying of products fully utilizes the tunnel oven's drying space, significantly improving work efficiency. Furthermore, the oven maintains uniform temperature, enhancing the post-curing quality of the product. The temperature of a tunnel oven can be controlled in stages, allowing for in-furnace cooling according to product process requirements. This reduces stress concentration caused by thermal shock, preventing cracking due to stress concentration.

[0004] Based on the above, this invention proposes a method for post-curing insulating products using a tunnel-type oven. This method is suitable for insulating products with high production volumes and stringent post-curing requirements. The tunnel-type oven comprises an outer shell, inner liner, support frame, heating system, air circulation system, transmission system, and electrical control system. The heating system is located in the air ducts on both sides of the working chamber, employing hot air circulation or infrared radiation heating, and is controlled by an independent electrical control cabinet. The air circulation system uses multiple circulating centrifugal fans. However, in the transmission section, existing conveying devices cannot automatically convey materials at set intervals and cannot prevent workpieces from impacting the sides of the oven. When discharging from the drying tunnel, the workpieces appear in random positions, posing a risk of them falling off. Summary of the Invention

[0005] This invention addresses the shortcomings of existing technologies by providing a post-curing tunnel device for insulating components.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution.

[0007] This invention provides a post-curing tunnel device for insulating components, comprising a conveyor belt and a chassis. A first partition is provided on the outer wall of the conveyor belt, and the chassis is snapped between adjacent first partitions. A tray is snapped onto the upper surface of the chassis, and insulating components are placed inside the tray. The conveyor belt is snapped onto a support frame via a rotating shaft. A heating device is provided on the upper surface of the support frame, and a second partition is fixedly connected to the inner wall of the heating device. A downward pressure shaft is hinged to the second partition, and the downward pressure shaft is interference-fitted with the upper surface of the insulating component. The lower surface of the second partition is friction-fitted with the outer wall of the tray. A baffle is provided at the outlet of the support frame, and the baffle is slidably fitted with the outer wall of the heating device via a sliding rod. The end of the sliding rod away from the baffle is fitted with a contact switch, which is controlled by a PLC.

[0008] Furthermore, each pair of adjacent first partitions has a first groove on its opposite side, and a slider is slidably fitted in the first groove. The slider is fixedly connected to the chassis, and two chassis are slidably fitted between each pair of first partitions. By setting the first groove and the slider, the chassis and the conveyor belt can be engaged more stably. Moreover, the cooperation between the first groove and the slider ensures that when the chassis shakes due to the stop or start of the conveyor belt, the shaking is controlled within a certain range, thereby effectively preventing collisions between two adjacent insulating components.

[0009] Furthermore, an elastic sheet is provided in the first groove, which contacts the slider. The width of the elastic sheet is greater than the width of the first groove. By providing the elastic sheet, when the insulating component shakes due to the stopping and starting of the conveyor belt, the elasticity of the elastic sheet will limit the shaking of the insulating component to a certain range. After the insulating component shakes, the elastic sheet will cause the insulating component to quickly return to its original position, thereby effectively preventing the collision between two adjacent insulating components, which effectively improves the quality of the post-curing of the insulating component.

[0010] Furthermore, gears are provided at both ends of the rotating shaft, and the gears mesh with a chain. The two ends of the rotating shaft are slidably engaged with the support frame. By setting gears and chains, all rotating shafts rotate synchronously. This synchronous rotation of the rotating shafts reduces deviations when the conveyor belt stops or starts, thereby reducing the likelihood of insulating components hitting the heating wall. The synchronous rotating shafts also allow for more precise positioning and stopping of the conveyor belt, thus effectively improving the efficiency of heating and curing the insulating components.

[0011] Furthermore, a sleeve is provided on the upper end face of the chassis, and a tray slides on the inner wall of the sleeve. A limiting block is provided in the tray, and the limiting block contacts the bottom end of the insulating component. By setting the sleeve and the limiting block, the insulating component is limited to a relatively fixed position, thereby reducing the possibility of the insulating component collapsing when the chassis shakes, further reducing the possibility of collision between adjacent insulating components, and thus effectively improving the working quality of the insulating component curing.

[0012] Furthermore, the outer wall of the tray is provided with an annular groove, and a slip ring is slidably fitted in the annular groove. The slip ring is fixedly connected to the inner wall of the sleeve. By providing the annular groove and the slip ring, the tray can rotate when the conveyor belt moves, so that the insulating parts can rotate, thereby making the heat curing of the insulating parts more uniform. The rotation of the insulating parts can also prevent shaking, thereby further reducing the collision of adjacent insulating parts.

[0013] Furthermore, the upper outer wall of the tray has frictional contact with friction blocks, the upper end face of the friction blocks is fixedly connected to the lower end face of the second partition, and the upper end face of the second partition is fixedly connected to the inner wall of the heating device. Through the friction blocks and their cooperation with the second partition, when the conveyor belt moves, the friction blocks rub against the tray, causing the tray to start rotating. The rotation of the tray drives the insulation components to rotate, thereby achieving more uniform heat curing of the insulation components. The rotation of the insulation components can also prevent shaking, further reducing the collision between adjacent insulation components.

[0014] Furthermore, the inner wall of the heating device is provided with a second groove, which is slidably engaged with both ends of the lower pressure shaft; by providing the second groove, the sliding engagement between the lower pressure shaft and the heating shaft is achieved.

[0015] Furthermore, the outer wall of the heating device is provided with a guide rail, which slides in conjunction with the sliding rod. The end face of the guide rail away from the baffle is fixedly connected to the sliding rod through an elastic element. A switch is provided at the end of the guide rail away from the baffle. By setting the guide rail and the elastic element, when the baffle is pushed by the insulating element, the sliding rod leaves the control switch, thereby triggering an alarm. When the insulating element stops pushing the baffle, the elastic element pulls the sliding rod, causing it to recompress the control switch, thereby deactivating the alarm. This completes the discharge control of the discharge port.

[0016] Furthermore, a power unit is provided on the side of the support frame, and the power unit is fixedly connected to the rotating shaft. The support frame is fixedly connected to the mounting plane. By setting the power unit on the World War II support frame, the power supply for the conveyor belt is realized.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This invention features a chassis that engages with the conveyor belt, reducing vibration caused by the belt stopping or starting through the cooperation of elastic and engaging components. The rotating chassis ensures even heating of the insulating components during curing, further minimizing vibration and collisions between adjacent components. Furthermore, the inclusion of baffles and an alarm device triggers a discharge alarm, thereby significantly improving the efficiency of the insulation curing process. Attached Figure Description

[0027] The present invention will now be described in further detail with reference to the accompanying drawings.

[0028] The following description is intended to disclose the invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious modifications will be apparent to those skilled in the art. The basic principles of the invention defined in the following description can be used in other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the invention.

[0029] Those skilled in the art should understand that, in the disclosure of this invention, the terms "longitudinal," "lateral," "upper," "lower," "left," "right," "front," "rear," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or position based on the orientation or positional relationship shown in the accompanying drawings. They are merely simplified descriptions for the convenience of describing this invention and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this invention.

[0030] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0031] This invention provides a post-curing tunnel device for insulating components, comprising a conveyor belt 1 and a chassis 2, as shown in the figure. Figure 1-6 The preferred chassis 2 is made of metal, and the conveyor belt 1 is made of high-temperature resistant material, thereby reducing shaking and damage caused by temperature changes during transportation. The outer wall of the conveyor belt 1 is provided with a first partition 3, and the chassis 2 is snapped between adjacent first partitions 3. The upper end face of the chassis 2 is snapped with a tray 4, and an insulating component is placed inside the tray 4. The conveyor belt 1 is snapped with a support frame 6 through a rotating shaft 5. The upper end face of the support frame 6 is provided with a heating device 7, and the inner wall of the heating device 7 is fixedly connected with a second partition 8. The second partition 8 is hinged with a lower pressure shaft 9, which is interference-fitted with the upper end face of the insulating component. The lower end face of the second partition 8 is friction-fitted with the outer wall of the tray 4. The discharge port of the support frame 6 is provided with a baffle 10, which is slidably fitted with the outer wall of the heating device 7 through a sliding rod 11. The end face of the sliding rod 11 away from the baffle 10 is fitted with a contact switch, which is controlled by a PLC.

[0032] In this configuration, two adjacent first partition plates 3 are provided with first grooves 12 on their opposing surfaces. A slider 13 is slidably engaged within the first groove 12. The slider 13 is fixedly connected to the chassis 2. Two chassis 2 are slidably engaged between every two first partition plates 3. By providing the first grooves 12 and sliders 13, the engagement between the chassis 2 and the conveyor belt 1 becomes more stable. Furthermore, the engagement of the first grooves 12 and sliders 13 ensures that when the chassis 2 shakes due to the stop or start of the conveyor belt 1, the shaking is controlled within a certain range, thereby effectively preventing collisions between two adjacent insulating components.

[0033] The first groove 12 is provided with an elastic sheet 14, which contacts the slider 13. The width of the elastic sheet 14 is greater than the width of the first groove 12. By providing the elastic sheet 14, when the insulating component shakes due to the stopping and starting of the conveyor belt 1, the elasticity of the elastic sheet 14 will keep the shaking of the insulating component within a certain range. After the insulating component shakes, the elastic sheet 14 will make the insulating component quickly return to its original position, thereby effectively avoiding collision between two adjacent insulating components, which effectively improves the quality of the post-curing of the insulating component.

[0034] The rotating shaft 5 has gears 15 at both ends, and the gears 15 mesh with chains 16. The two ends of the rotating shaft 5 are slidably engaged with the support frame 6. By setting the gears 15 and chains 16, all rotating shafts 5 rotate synchronously. This allows the rotating shafts 5 to rotate synchronously when the conveyor belt 1 stops or starts, reducing deviations and minimizing the impact of insulating components on the heating wall. Furthermore, the synchronous rotating shafts 5 enable more precise positioning and stopping of the conveyor belt, thereby effectively improving the efficiency of heating and curing the insulating components.

[0035] The upper surface of the chassis 2 is provided with a sleeve 17, and a tray 4 slides on the inner wall of the sleeve 17. A limiting block 18 is provided in the tray 4, and the limiting block 18 contacts the bottom end of the insulating component. By setting the sleeve 17 and the limiting block 18, the insulating component is limited to a relatively fixed position, thereby reducing the possibility of the insulating component collapsing when the chassis 2 shakes, and further reducing the possibility of collision between adjacent insulating components, thus effectively improving the work quality of the insulating component curing.

[0036] The outer wall of the tray 4 is provided with an annular groove 19, and a slip ring 20 is slidably fitted in the annular groove 19. The slip ring 20 is fixedly connected to the inner wall of the sleeve 17. By providing the annular groove 19 and the slip ring 20, the tray 4 can rotate when the conveyor belt 1 moves, so that the insulating parts can rotate, thereby making the heat curing of the insulating parts more uniform. The rotation of the insulating parts can also prevent shaking, thereby further reducing the collision of adjacent insulating parts.

[0037] The upper outer wall of the tray 4 has a friction block 21 in frictional contact. The upper end face of the friction block 21 is fixedly connected to the lower end face of the second partition 8, and the upper end face of the second partition 8 is fixedly connected to the inner wall of the heating device 7. Through the friction block 21 and its cooperation with the second partition 8, when the conveyor belt 1 moves, the friction block 21 and the tray 4 rub against each other, causing the tray 4 to start rotating. The rotation of the tray 4 drives the insulation component to rotate, thereby achieving more uniform heat curing of the insulation component. The rotation of the insulation component can also prevent shaking, thereby further reducing the collision of adjacent insulation components.

[0038] The heating device 7 has a second groove 22 on its inner wall, and the second groove 22 is slidably engaged with both ends of the lower pressure shaft 9. By setting the second groove 22, the sliding engagement between the lower pressure shaft 9 and the heating device 7 is achieved.

[0039] The heating device 7 has a guide rail 23 on its outer wall, which slides in conjunction with the sliding rod 11. The end face of the guide rail 23 away from the baffle 10 is fixedly connected to the sliding rod 11 through an elastic element 24. A switch is provided at the end of the guide rail 23 away from the baffle 10. By setting the guide rail 23 and the elastic element 24, when the baffle 10 is pushed by the insulating element, the sliding rod 11 leaves the control switch, thus triggering an alarm. When the insulating element stops pushing the baffle 10, the elastic element 24 pulls the sliding rod 11, causing it to recompress the control switch, thereby deactivating the alarm. This completes the discharge control of the discharge port.

[0040] The support frame 6 is equipped with a power unit on its side, which is fixedly connected to the rotating shaft 5. The support frame 6 is also fixedly connected to the mounting plane. The power unit is installed on the support frame 6 to provide power to the conveyor belt 1.

The objectives of the present invention have been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments, and any modifications or variations of the embodiments of the present invention may be made without departing from the stated principles.
