Description

Technical Field

[0001] The invention relates to the technical field of automobile sealing strip processing, in particular to a hot air collecting device for automobile sealing strip processing. Background Art

[0002] Automobile sealing strips have the function of filling various intervals and gaps between the components of the car body. In the multiple steps of automobile sealing strip processing, the sealing strips will be heated, including shaping, hot pressing and other steps, which will cause the temperature of the working environment to be higher, which can easily cause dehydration, heatstroke and other conditions for the workers.

[0003] To this end, Chinese patent CN221136609U discloses a cooling device for automobile sealing strip processing, which sprays cold water evenly onto the sealing strip through the cooperation of a water spray pipe and a nozzle, recovers the cooling water through the cooperation of a water leakage hole and a circulation box, cools the recovered water through a semiconductor refrigeration sheet, draws the re-cooled water into the connecting pipe through the cooperation of a water pump, a circulation pipe and a connecting pipe, and then sprays it out from the water spray pipe and the nozzle again, so that the cooling water is recycled to cool the sealing strip.

[0004] However, most of the existing cooling devices actively cool the sealing strips, while some processing techniques do not require cooling of the sealing strips. For example, before installing the sealing strips, a hot air blower is needed to heat and soften the sealing strips to enhance the adhesion of the sealing strips and ensure that the sealing strips fit well with the car body or other components. During this process, the sealing strips do not need to be cooled separately. However, the large amount of heat provided by the hot air blower is directly dispersed into the working environment, which will cause the temperature of the working environment to increase significantly. However, when the sealing strips are directly cooled by cooling devices such as air conditioners, the sealing strips will come into direct contact with the cold air flow after heating, which will cause local temperature differences in the sealing strips due to uneven temperature. The sealing strips will expand and contract when heated or cooled, so they cannot be directly cooled by cold air and can only be actively collected. Summary of the invention

[0031] Reference Figure 1-Figure 7A hot air collecting device for processing automobile sealing strips is arranged on a frame 1 on which a hot air blower 11 is installed, and an exhaust pipe 12 is arranged on the frame 1. The hot air collecting device includes a heat insulation cover 2 and a control mechanism 3; a first mounting frame 21 and a second mounting frame 22 are arranged in the heat insulation cover 2; a first fan 211, a grille 212 and a first baffle 213 are arranged on the first mounting frame 21; the first fan 211 is rotatably arranged on the first mounting frame 21, and a pipeline connected to the exhaust pipe 12 is arranged on the first mounting frame 21, the first baffle 213 is slidably matched with the grille 212, and a rotating driver 214 for driving the first fan 211 to rotate is built in the first mounting frame 21; a second fan 211 is arranged on the second mounting frame 22 21, a connecting plate 222 and a second baffle 223, the connecting plate 222 is provided with pipes connected to the hot air blower 11 and the exhaust pipe 12 respectively, and the second baffle 223 is movably arranged on the second mounting frame 22; the control mechanism 3 is used to control the movement of the first baffle 213 and the second baffle 223; in the working state, when the hot air blower 11 is in the starting state, the control mechanism 3 controls the movement of the first baffle 213, and blocks the pipe on the first mounting frame 21 through the first baffle 213 and the grille 212, and at the same time, the control mechanism 3 controls the movement of the second baffle 223, opens the pipe on the connecting plate 222 connected to the hot air blower 11, and closes the pipe on the connecting plate 222 connected to the exhaust pipe 12 through the second baffle 223.

[0032] The present invention realizes the function of collecting the hot air blown by the hot air blower 11 through the heat insulation cover 2, the first mounting frame 21, the second mounting frame 22 and the control mechanism 3, and achieves the effect of recovering the hot air in the working state and exhausting the hot air in the shutdown state through the cooperation of the first fan 211 and the second fan 221, thereby solving the problem that the hot air blown by the hot air blower 11 during the processing of the automobile sealing strip has a great impact on the working environment. The flow direction of the hot air flow is as follows: Figure 4As shown by the middle arrow, and the airflow is shown by the thin arrow when hot air is collected. The pipe used to connect the exhaust pipe 12 is not shown in the figure. In order to enable the pipe to connect the exhaust pipe 12 and to improve the cleanliness of the working environment, the pipes are all arranged inside the frame 1. The frame 1 is provided with a controller for human-machine interaction. The rotary drive 214 is preferably a servo motor, and the servo motor is electrically connected to the controller; when the hot air blower 11 is started to process the workpiece, the first baffle 213 and the second baffle 223 are controlled by the control mechanism 3 to move, and the pipe on the first mounting frame 21 is blocked by the first baffle 213 and the grille 212, and the pipe on the connecting plate 222 connected to the hot air blower 11 is opened at the same time, and the pipe on the connecting plate 222 connected to the exhaust pipe 12 is closed by the second baffle 223, so that after the hot air flow blown out by the hot air blower 11 heats the workpiece, the air flow enters the hot air blower 11 again through the second fan 221 for heating and then blown out, thereby reusing the hot air flow and improving the hot air flow. 11, at this time, the hot air flow is separated by the insulation cover 2 to avoid a greater impact on the working environment. After the processing is completed, when taking and placing the material, the first baffle 213 and the second baffle 223 are controlled to move by the control mechanism 3 again, so that the first baffle 213 and the grille 212 are misaligned, the pipeline on the first mounting frame 21 is opened, and at the same time, the pipeline on the connecting plate 222 connected to the hot air blower 11 is blocked by the second baffle 223, the pipeline on the connecting plate 222 connected to the exhaust pipe 12 is opened, and the first fan 211 is driven to rotate by the rotary driver 214, a negative pressure is generated at the first mounting frame 21, the hot air flow is attracted, and the residual hot air in the insulation cover 2 is discharged through the exhaust pipe 12. At this time, the air flow enters from the second fan 221 and is discharged from the first fan 211, and the air inlet and outlet are both connected to the exhaust pipe 12, and will not pass through the hot air blower 11 and the working environment, thereby reducing the impact of the hot air on the working environment.

[0033] Reference Figure 4-Figure 8 : The control mechanism 3 includes a control component 31 and a linear drive component 32; the control component 31 is used to control the movement of the first baffle 213; the linear drive component 32 is used to control the movement of the second baffle 223; a transmission mechanism 4 is also provided on the frame 1, and the control component 31 is connected to the linear drive component 32 through the transmission mechanism 4; in the working state, when the control component 31 controls the movement of the first baffle 213 so that the first baffle 213 and the grille 212 block the pipe on the first mounting frame 21, the control component 31 drives the linear drive component 32 through the transmission mechanism 4, and the linear drive component 32 controls the movement of the second baffle 223 so that the second baffle 223 blocks the pipe on the connecting plate 222 for connecting the exhaust pipe 12.

[0034] The present invention realizes automatic control of the movement of the second baffle 223 when the first baffle 213 moves through the control component 31, the linear drive component 32 and the transmission mechanism 4, so that when the pipe of the first mounting frame 21 is closed, the recovery of the hot air flow can be stably controlled, and when the pipe of the first mounting frame 21 is opened, the hot air flow can also be stably absorbed. If the pipe on the second mounting frame 22 and the exhaust pipe 12 is in a closed state, it will affect the air intake efficiency and then affect the hot air collection efficiency. For this reason, the transmission connection of the transmission mechanism 4 is used to simultaneously control the movement of the first baffle 213 and the second baffle 223, so that the transmission path of the airflow is stably controlled. When the hot air blower 11 is started to process the workpiece, the first baffle 213 is controlled to move through the control component 31, and at the same time, the control component 31 drives the linear drive component 32 through the transmission mechanism 4, and then the second baffle 223 is controlled to move through the linear drive component 32, and the pipe on the first mounting frame 21 is blocked by the first baffle 213 and the grille 212, and at the same time, the pipe on the connecting plate 222 connected to the hot air blower 11 is opened, and the pipe on the connecting plate 222 connected to the exhaust pipe 12 is closed by the second baffle 223, so that the hot air flow blown out by the hot air blower 11 heats the workpiece, and then enters the hot air blower 11 again through the second fan 221 to be heated and then blown out, thereby making secondary use of the hot air flow.

The linear drive 315 is preferably a linear cylinder, which is electrically connected to the controller; when the first baffle plate 213 is in a reset state, the pipeline on the first mounting bracket 21 is opened; when controlling the first baffle plate 213 to move, a signal is sent to the linear drive 315 through the controller, and the linear drive 315 drives the push block 313 to move after receiving the signal, and the push block 313 pushes the lever 312 abutting against it, thereby pushing the lever 312 to rotate, and then the other end of the lever 312 pushes the first abutment plate 314 on the first baffle plate 213, and the first baffle plate 213 is driven to move through the first abutment plate 314, and when it is necessary to open the pipeline on the first mounting bracket 21, the push block 313 is controlled to reset by the linear drive 315, and the lever 312 is no longer squeezed by the push block 313, and the first baffle plate 213 is reset under the control of the reset assembly 33, and the first abutment plate 314 on the first baffle plate 213 pushes the lever 312 to rotate until the first baffle plate 213 is completely reset.

At this time, the elastic member 333 still has a pre-tightening force on the second abutment plate 331, thereby ensuring that the first baffle 213 is in a stable reset state. After the linear drive 315 drives the push block 313 to push the lever 312 to rotate, the lever 312 needs to overcome the elastic force of the elastic member 333 when pushing the first abutment plate 314.
