Description

Technical Field

[0001] The utility model relates to the technical field of fume collecting hoods, in particular to a fume collecting hood for a rubber vulcanizing machine manipulator. Background Art

[0002] As we all know, tires need to be vulcanized during the production process, and the vulcanization process often produces a lot of VOC waste gas; the collection of VOC waste gas in the vulcanization workshop of the tire factory is mainly done by building a sealed room for the entire vulcanization production line, or a sealed room for the entire vulcanizer. This kind of space collection is not done at a fixed point. This collection method has poor waste gas collection effect, large air volume, high investment cost, great construction difficulty, high escape rate, and high operating cost; some tire factories also use mobile VOC waste gas fixed-point collection devices.

[0003] For example, a Chinese utility model patent discloses a movable waste gas collection device for tire vulcanization (publication (announcement) number CN210850986U), including a lifting arm, a gas collecting cover, an open mold and a rotating mechanical arm. The lower end of the lifting arm is provided with a fixed plate, and the lifting arm is connected to the gas collecting cover through the fixed plate. The gas collecting cover is a hollow sandwich structure, and one side of the gas collecting cover is connected to an exhaust air induced hose. The lower end of the gas collecting cover is provided with an open mold, one end of the rotating mechanical arm is connected to a gas collecting hood, and one side of the gas collecting hood is connected to an exhaust air induced hose, and the rotating mechanical arm is connected to a mechanical claw. The movable waste gas collection device for tire vulcanization is provided with a gas collecting cover and a lifting cylinder to form a whole. When the lifting cylinder moves up and down, the gas collecting cover can also move up and down. Such a design can adjust the position of the gas collecting cover according to the actual situation on site, thereby improving the applicability of the device, while also greatly reducing the gas collecting area and improving efficiency.

[0004] However, when the inventors implemented this device, they found the following defects: after the tire is vulcanized, although the VOC waste gas around the tire vulcanizer can be collected by the above device, the VOC waste gas after the vulcanization treatment mainly remains in the inner cavity of the tire. This part of the waste gas is difficult to be completely collected by the above device, and has certain limitations in use. Utility Model Content

The exhaust gas in the inner cavity of the tire can be collected and processed, and the residual exhaust gas is reduced, and the structural layout is more reasonable.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-5The utility model is a rubber vulcanizer manipulator fume collection hood, comprising a hood 1, an inner support clamping manipulator installed in the hood 1, a plate piston 2 slidably installed in the hood 1, a suction cup 3, a plurality of connecting pipes 4 and a one-way wind blocking mechanism installed on the top of the hood 1, the one-way wind blocking mechanism only allows the airflow in the hood 1 to be transported outward; the suction cup 3 is connected to the hood 1 as a whole through a plurality of connecting pipes 4, one end of the connecting pipe 4 extends into the suction cup 3, and the other end of the connecting pipe 4 extends into the top of the hood 1; a driving cylinder 5 is fixedly installed on the suction cup 3, and the driving cylinder 5 provides driving force for the lifting and lowering of the plate piston 2 and the opening and closing of the inner support clamping manipulator; further, the external manipulator arm can be connected to the cylinder 8, the tire can be clamped and fixed by the inner support clamping manipulator, and the vulcanized tire can be unloaded in cooperation with the external manipulator arm, and the operation is convenient.

[0026] Specifically, the inner support clamping robot includes a plurality of support claws 6 and a plurality of transmission rods 7 which are radially arranged for sliding along the suction cup 3. One end of the transmission rod 7 is hinged to the support claws 6, and the other end of the transmission rod 7 is hinged to the output end of the drive cylinder 5. By starting the drive cylinder 5, the output end of the drive cylinder 5 is shortened, and after being transmitted by the transmission rod 7, the support claws 6 are inserted into the inner cavity of the tire to clamp the tire, so that the cover tube 1 and the tire are tightly fitted together. At the same time, the inner support clamping robot can provide guarantee for the subsequent unloading of the tire.

[0027] Specifically, the one-way wind-blocking mechanism includes a cylinder 8, a rotating shaft 9 installed on the cylinder 8, two valve plates 10 hingedly installed on the rotating shaft 9 and matching the inner diameter of the cylinder 8, and a torsion spring 11. A cross brace 12 is fixedly installed in the cylinder 8, and the torsion spring 11 is sleeved on the rotating shaft 9. The valve plate 10 is elastically connected to the cross brace 12 through the torsion spring 11; further, in a natural state, under the action of the torsion spring 11, the two valve plates 10 are parallel to each other and completely block the cylinder 8; in the process of the plate piston 2 moving downward from the cover cylinder 1, the valve plate 10 blocks the top of the cover cylinder 1 to prevent external airflow from entering the top of the cover cylinder 1, so that a negative pressure effect is generated on the top of the cover cylinder 1.

[0028] Specifically, a one-way valve 13 is provided at the top of the connecting pipe 4, which only allows the air in the suction cup 3 to flow to the top of the cover tube 1; further, the one-way valve 13 is a conventionally known product on the market, and its specific structure and principle are not further described here; when the driving cylinder 5 drives the plate piston 2 to move toward the upper part of the cover tube 1, the air pressure in the upper part of the cover tube 1 increases, and the one-way valve 13 is closed to prevent the exhaust gas from flowing back into the inner cavity of the tire through the connecting pipe 4. At this time, the valve plate 10 rotates around the rotating shaft 9, and the valve plate 10 disengages from the blockage of the cylinder 8, allowing the exhaust gas to be discharged.

[0029] Specifically, an annular baffle 14 is provided at the bottom edge of the cover cylinder 1; the annular baffle 14 can increase the contact area between the cover cylinder 1 and the tire, and improve the fit and sealing between the cover cylinder 1 and the tire.

[0030] Specifically, a plurality of slide rails 15 radially arranged along the suction cup 3 are fixedly mounted on the suction cup 3 , and the claw 6 can be slidably mounted on the slide rails 15 ; the sliding track of the claw 6 can be limited by the slide rails 15 , thereby improving the sliding stability of the claw 6 .

[0031] Specifically, the support claw 6 is rotatably mounted with at least two clamping columns 16, which are screwed onto the support claw 6; further, the clamping columns 16 on the multiple support claws 6 are enclosed in a ring shape; through the clamping columns 16, the depth of the support claw 6 extending into the inner cavity of the tire can be limited, and at the same time, the contact area between the support claw 6 and the tire can be increased, effectively preventing the tire from moving at the inner support clamping robot, thereby improving the clamping stability of the tire.

[0032] Specifically, the claw 6 is provided with a plurality of evenly distributed screw holes 17; the installation position of the clamping column 16 on the claw 6 can be adaptively adjusted according to the inner diameter size of the tire to meet the clamping requirements of tires with multiple inner diameters and improve applicability.

[0033] When in use, the suction cup 3 is extended to the bottom of the tire, the cover cylinder 1 is placed on the top of the treated tire, and the driving cylinder 5 drives the plate piston 2 to move downward. At this time, the one-way air-blocking mechanism is in a closed state, and the plate piston 2 presses the air in the cover cylinder 1 into the inner cavity of the tire. At this time, the bottom of the tire is still in close contact with the vulcanizer. As the pressure in the inner cavity of the tire increases and a negative pressure effect is generated on the upper part of the cover cylinder 1, the residual exhaust gas enters the upper part of the cover cylinder 1 through the connecting pipe 4, so as to collect the residual exhaust gas in the inner cavity of the tire. Subsequently, the driving cylinder 5 drives the plate piston 2 to reset. At this time, the one-way valve 13 is closed, the air pressure in the upper part of the cover cylinder 1 increases, the one-way air-blocking mechanism is opened, and the exhaust gas is discharged to the external exhaust gas treatment equipment.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
