Description

Technical Field

[0001] This application relates to the field of tire bladder processing, and more particularly to a cooling conveying device for tire vulcanizing bladder extrusion. Background Technology

[0002] Tire vulcanizing bladders are key components inserted into the inner cavity of the tire blank during the tire vulcanization process. They are typically made of butyl rubber and have a hollow, thin-walled structure. Their main function is to achieve expansion and shaping by filling with compressed air, nitrogen, or superheated water. They also function as a heat transfer medium and pressure transmission medium. The vulcanizing bladder expands and shapes by filling with compressed air, nitrogen, or superheated water, ensuring the tire maintains its correct shape during vulcanization. During vulcanization, the bladder acts as a heat transfer medium, helping to evenly transfer heat to all parts of the tire, improving the vulcanization effect. The pressure inside the bladder is evenly transferred to the tire blank, ensuring uniform pressure on all parts of the tire during vulcanization, improving vulcanization quality. Tire vulcanizing bladders often require a cooling conveyor for transport and cooling during processing. In conventional cooling conveyor systems, after the transfer frame is installed stably, several rotating rods are rotatably connected to the inner wall of the transfer frame. A control motor is installed at one end of each rotating rod, which starts and rotates the rod, moving the material at the top of the rod. A fan is installed on the surface of the transfer frame to cool the material at the top of the rotating rod.

[0003] Regarding the aforementioned technologies, the inventors believe that conventional cooling and conveying devices often use airflow to dissipate heat from material racks. However, tire vulcanizing bladders often produce mobile toxic gases after heating. Conventional airflow cooling can easily cause the toxic gases to spread, polluting the surrounding air and affecting the health of workers.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

The top of the wind box is fixedly connected to the inner wall of the transmission frame, and the center of the wind box and the center of the filter are on the same straight line. The negative pressure fan is composed of a fan casing, a motor, and fan blades.

[0007] Preferably, the inner wall of the filter is fixedly equipped with a preliminary filtration layer and a secondary filtration layer, wherein the preliminary filtration layer is an activated carbon filtration layer and the secondary filtration layer is a HEPA high-efficiency filtration layer.

[0008] Preferably, one end of the negative pressure fan is fitted with a shield, and the center of the shield is on the same straight line as the center of the negative pressure fan.

The toxic gases are then discharged from the negative pressure fan end after being filtered by the filter. The inner wall of the filter is equipped with a preliminary filter with an activated carbon filter layer and a secondary filter layer with a HEPA high-efficiency filter layer. The preliminary filter adsorbs harmful substances such as formaldehyde and smoke, while the secondary filter layer captures fine particles larger than 0.3 microns in the gas.

[0017] This application discloses a cooling and conveying device for tire vulcanizing bladder extrusion, referring to... Figure 1 - Figure 2 The system includes a transmission frame 1. During use, after the transmission frame 1 is installed stably, several rotating rods 2 are rotatably connected to the inner wall of the transmission frame 1. A control motor 3 is installed at one end of each rotating rod 2. The control motor 3 starts and controls the rotating rod 2 to rotate, causing the material at the top of the rotating rod 2 to move. A bellows 4 is installed on the inner wall of the transmission frame 1. A filter 5 is connected to the bottom of the bellows 4. A negative pressure fan 6 is connected to one end of the filter 5. When the negative pressure fan 6 is started, it generates negative pressure airflow, causing the bellows 4 to draw in toxic gases produced by the material and cool the material. The toxic gases are then filtered by the filter 5 and discharged from one end of the negative pressure fan 6, effectively improving the environmental friendliness of tire bladder processing and avoiding the problem of toxic gas diffusion causing pollution to the surrounding air.

[0018] Reference Figure 2 The inner wall of filter 5 is equipped with a preliminary filter 5 with an activated carbon filter layer and a secondary filter layer 8 with a HEPA high-efficiency filter layer. The preliminary filter 5 adsorbs harmful substances such as formaldehyde and smoke, and the secondary filter layer 8 captures fine particles larger than 0.3 microns in the gas, effectively removing pollutants from the air. A shield 9 is installed at one end of the negative pressure fan 6.

[0020] The implementation principle of a cooling and conveying device for tire vulcanizing bladder extrusion according to an embodiment of this application is as follows: A blower box 4 is installed on the inner wall of a transmission frame 1. A filter 5 is connected to the bottom of the blower box 4, and a negative pressure fan 6 is connected to one end of the filter 5. This allows the negative pressure fan 6 to generate negative pressure airflow, causing the blower box 4 to draw in toxic gases generated by the material and cool the material. The toxic gases are then discharged from the negative pressure fan 6 after being filtered by the filter 5, preventing the diffusion of toxic gases and pollution of the surrounding air. The inner wall of the filter 5 is equipped with a preliminary filter 5 with an activated carbon filter layer and a secondary filter layer 8 with a HEPA high-efficiency filter layer, facilitating the preliminary filtration of the toxic gases. Filter 5 adsorbs harmful substances such as formaldehyde and smoke, and works with secondary filter layer 8 to capture fine particles larger than 0.3 microns in the gas, effectively removing pollutants from the air. A shield 9 is installed at one end of the negative pressure fan 6 to guide the airflow discharged from one end of the negative pressure fan 6, avoiding direct airflow from disturbing people or objects in the vicinity, and preventing external impurities from entering the negative pressure fan 6. Two connecting blocks 10 are installed at one end of the shield 9. Fixing bolts 11 are snapped into the inner wall of the connecting blocks 10. The surface of the fixing bolts 11 is threaded to the inner wall of the negative pressure fan 6, so that the shield 9 can be installed at one end of the negative pressure fan 6 by means of fixing bolts 11 and connecting blocks 10.

[0021] A sliding frame 12 can also be installed on the inner wall of the air box 4.

Two limiting frames 14 are rotatably installed on one end of the sliding frame 12. One end of the limiting frame 14 is engaged with the slot 15 on the surface of the air box 4, so that the sliding frame 12 and the air box 4 can be connected by the limiting frame 14 and the slot 15, thereby ensuring the shielding effect of the shielding net 13 inside the sliding frame 12.
