Description

Technical Field

[0001] This utility model belongs to the field of sealing strip processing technology, specifically relating to a rapid curing device for automotive sealing strip processing. Background Technology

[0002] In the automotive sealing strip manufacturing industry, traditional rapid curing devices face numerous unresolved issues. From a curing effect perspective, most traditional devices employ a single-sided or top-mounted high-temperature airflow method. This airflow pattern has significant drawbacks. Due to the inherent structural characteristics of the sealing strip, the bottom is easily obstructed by the sealing strip itself, making it difficult for the hot airflow to effectively cover the surface. This results in uneven curing, with the top curing faster than the bottom. This uneven curing not only leads to inconsistent product quality, poor sealing, and insufficient elasticity, but also significantly prolongs the overall curing cycle, severely impacting production efficiency. Utility Model Content

[0003] To address the above problems, the purpose of this utility model is to provide a rapid curing device for processing automotive sealing strips, thereby solving the aforementioned issues.

[0004] To achieve the above objectives, a rapid curing device for processing automotive sealing strips includes a curing equipment assembly. The curing equipment assembly includes a curing equipment body and a conveying device. A mounting frame is installed inside the curing equipment assembly. Lower air supply pipes are installed on both sides of the mounting frame, and an upper air supply pipe is installed on the mounting frame. The upper air supply pipe is connected to the curing equipment body through a fixing frame. A connecting pipe A is installed at the bottom of the upper air supply pipe, and an air guide pipe is opened on the connecting pipe A. A restraining assembly is supported on the conveying device. The restraining assembly includes a limiting shell, a sliding rod, a friction pad, a connecting pipe, and an exhaust hole. The exhaust hole is located below the limiting shell. A connecting pipe B is connected to the sliding rod, and several connecting pipes are connected to the connecting pipe B. The connecting pipe B is slidably connected to the bottom end of the upper air supply pipe.

[0017] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0018] Example 1:

[0019] like Figure 1As shown in Figure 4, this utility model provides the following technical solution: It includes a curing equipment component 1, which includes a curing equipment body 11 and a conveying device 12. A mounting frame 2 is installed inside the curing equipment component 1. Lower air supply pipes 21 are installed on both sides of the mounting frame 2. An upper air supply pipe 14 is installed on the mounting frame 2. The upper air supply pipe 14 is connected to the curing equipment body 11 through a fixing frame 13. A connecting pipe A15 is installed at the bottom of the upper air supply pipe 14. An air guide pipe 16 is opened on the connecting pipe A15. A binding component 3 is supported on the conveying device 12. The binding component 3 includes a limiting shell 31, a sliding rod 32, a friction pad 33, a connecting pipe 34, and an exhaust hole 35. The exhaust hole 35 is located below the limiting shell 31. A connecting pipe B36 is connected to the sliding rod 32. Several connecting pipes 34 are connected to the connecting pipe B36. The connecting pipe B36 is slidably connected to the bottom end of the upper air supply pipe 14.

[0020] In this implementation scheme: the curing equipment component 1 is used to heat the sealing strip, so that after the sealing strip is placed in the curing equipment component 1, it can be quickly vulcanized and cured at an appropriate high temperature. During use, the sealing strip is transported into the curing equipment component 1 by the conveying device 12, and several sealing strips are engaged between two limiting shells 31, so that both ends of the sealing strip are engaged in the limiting shells 31 respectively, so that several sealing strips can correspond to the connecting pipe 34 between the sliding rods 32. At this time, the connecting pipe 34 is below the sealing strip, and the connecting pipe 32... The exhaust port 35 on the 4th surface can maintain its alignment with the bottom of the sealing strip. When the slide rod 32 is driven by the conveying device 12 to move into the curing equipment assembly 1, the sealing strip installed between the limiting shells 31 moves synchronously with it and enters the inner cavity of the curing equipment assembly 1. At this time, the lower air supply pipe 21 can be installed through the mounting bracket 2 installed inside the curing equipment assembly 1. At this time, the lower air supply pipe 21 is located on both sides inside the curing equipment assembly 1. The lower air supply pipe 21 is connected to the high-temperature air supply equipment, so that the lower air supply pipe 21 can apply high-temperature air to the seal. On the strip, the curing speed of the sealing strip is increased. At the same time, when the limiting shell 31 and the slide rod 32 enter the curing equipment assembly 1, the upper air supply pipe 14 installed on the mounting frame 2 can be connected to the connecting pipe A15. The upper air supply pipe 14 is also connected to the high-temperature air supply equipment, so that the high-temperature gas can enter the connecting pipe A15 and be discharged through the air guide pipe 16 installed at the bottom of the connecting pipe A15. When the top of the connecting pipe B36 installed on the slide rod 32 is in contact with the bottom of the connecting pipe A15, when the connecting pipe B36 and the slide rod 32 move synchronously, the connecting pipe B36... After the position of 36 corresponds to that of the air guide pipe 16, the high-temperature gas in the air guide pipe 16 can be transmitted to the inner cavity of the slide rod 32 through the connecting pipe B36. At this time, the connecting pipe 34 is connected to the inner cavity of the slide rod 32, so that the exhaust hole 35 opened on the connecting pipe 34 can discharge the high-temperature gas. This allows the bottom of the sealing strip to be affected by the high-temperature gas transported by the device, ensuring the vulcanization speed of the bottom of the sealing strip. This avoids the bottom of the sealing strip being blocked by itself during the vulcanization process, resulting in poor effect of the high-temperature gas acting on the bottom of the sealing strip and affecting its overall curing efficiency.

[0021] The outlet of the lower air duct 21 is tilted toward the center of the conveying equipment 12, and the lower air duct 21 is misaligned with the binding component 3. Since the lower air duct 21 is located on both sides of the inner cavity of the curing equipment component 1, it makes way for the connection between the connecting pipe B36 and the connecting pipe A15 and the air guide pipe 16. The lower air duct 21 is tilted toward the displacement position of the sealing strip, so that the high temperature gas output from the lower air duct 21 can act on the sealing strip.

[0022] The limiting shell 31 is installed on one side of the slide rod 32, and the connecting pipe B36 is connected to the connecting pipe A15. The limiting shell 31 is connected to the slide rod 32 so that when the slide rod 32 is driven by the conveying device 12, it can move synchronously with it, so that the sealing strip supported between the limiting shells 31 can be conveyed and enter the curing equipment assembly 1. The connecting pipe B36 is connected to the connecting pipe A15 so that the exhaust hole 35 conveys the high temperature gas to the connecting pipe 34 through the air guide pipe 16, and then acts on the bottom of the sealing strip through the connecting pipe B36.

[0023] Two extension rods 371 are installed at one end of the curing equipment assembly 1. A positioning rod 37 corresponding to the extension rods 371 is installed above the conveying equipment 12. The two ends of the slide rod 32 are slidably connected to the positioning rod 37 and the extension rod 371. The two extension rods 371 installed at one end of the curing equipment assembly 1 can temporarily support the limiting shell 31 and the slide rod 32 on the outside of the conveying equipment 12. The extension rods 371 are kept in correspondence with the positioning rod 37. The positioning rod 37 and the extension rod 371 limit the limiting shell 31 and the slide rod 32, so that the limiting shell 31 and the slide rod 32 can be horizontally conveyed into the curing equipment assembly 1.

[0024] A friction pad 33 is installed at the bottom of the slide rod 32, and sliders 381 are installed at both ends of the slide rod 32. The positioning rod 37 and the extension rod 371 are provided with slide tracks 38 that match the sliders 381. The two sliders 381 are connected by a limiting rod 382. The friction pad 33 installed at the bottom of the slide rod 32 can increase the friction between the conveying device 12 and the slide rod 32, ensuring that the conveying device 12 can convey the slide rod 32 and cause the sealing strip to move. The slide track 38 is used to limit the sliders 381 installed at both ends of the slide rod 32. The limiting rod 382 passes through the slider 381 to ensure that the displacement of the slide rod 32 is limited, so that the connecting pipe B36 can keep corresponding with the air guide pipe 16 and avoid deviation.

[0025] The curing equipment assembly 1 is equipped with a bracket 17 for supporting the upper air duct 14. The bracket 17 is offset from the restraint assembly 3. The bracket 17 is used to support and erect the upper air duct 14 to ensure that the upper air duct 14 can maintain a fixed height, so that the connecting pipe A15 connected below the upper air duct 14 can maintain a fixed height, so that the air guide pipe 16 can transport the high temperature gas to the connecting pipe B36.

[0026] The working principle of this technical solution is as follows: First, the equipment is pre-processed. During batch processing, the two ends of the sealing strip are evenly clamped along the slide bar 32, ensuring that the bottom of the sealing strip corresponds to the exhaust hole 35. After gently pulling to confirm that there is no looseness, the conveying and curing are started. The conveying equipment 12 is turned on to drive the slide bar 32 to move along the track into the curing equipment assembly 1. The sliding state of the slider 381 is observed. When the sealing strip enters the interior of the curing equipment assembly 1, the high-temperature air supply equipment is turned on. Dual heating is achieved through the lower air supply pipe 21 and the upper air supply pipe 14. Hot air is supplied to the connecting pipe A15 by 14. Hot air is blown towards the bottom of the sealing strip through the air duct 16 → connecting pipe B36 → connecting pipe 34 → exhaust hole 35. The temperature is consistent with that of the lower air supply pipe 21. During the process, the sealing strip is monitored for any deviation. After curing is completed, the time is set according to the material. The equipment is turned off and the slide rod 32 is removed from the curing equipment component 1. The sealing strip is removed from the limiting shell 31 while wearing gloves, and its quality, elasticity, and stickiness are checked. Finally, subsequent maintenance is performed. The airflow channel is cleaned with compressed air, the surface of the limiting shell 31 of the slide rod 32 is wiped, the slide rod 32 is pushed back to the initial position, and the power is turned off. The processing parameters for this operation are recorded for reuse.
