Description

Technical Field

[0001] The utility model belongs to the technical field of rubber processing, and in particular relates to a rubber part processing preheating device. Background Art

[0002] Rubber parts refer to components or products made of rubber materials, which are usually used to manufacture seals, shock absorbers, conveyor belts, automobile tires, gaskets and other industrial and daily necessities. When preheating rubber parts, the temperature and heating method of the preheating furnace are usually adjusted to achieve the preheating of rubber parts cut into blocks or granules.

[0003] Patent CN216181879U discloses a rubber processing preheating device, which, through the coordinated use of a servo motor, a rotating shaft, a fixed block, a scraper block, a scraper strip, a rotating rod, a gear and an inner gear ring, stirs and heats the rubber in a heating tank so that it is heated evenly, and scrapes and stirs the heated rubber at the bottom and inner wall of the heating tank to prevent adhesion caused by excessive temperature.

[0004] Patent CN220095160U discloses a rubber processing preheating device, in which a circular scraper ring is arranged inside the heating cylinder. When melted rubber is stuck on the inner wall of the heating cylinder, the first motor is turned on, and the first motor drives the threaded screw to rotate, and the threaded screw drives the circular scraper ring to slide on the inner wall of the heating cylinder, so that the rubber stuck on the inner wall of the heating cylinder can be scraped off.

[0005] In the above scheme, after the rubber is preheated, the rubber will be taken out through the discharge pipe or the discharge port. When the rubber is taken out, the device will stop working. However, the rubber that the device can preheat at one time is limited. When preheating a large amount of rubber, the device will be used multiple times. After the device stops working, the heat in the device will gradually dissipate. When the device is used again, it needs to be reheated, which will cause a waste of resources. In addition, it will consume a lot of time when taking out the rubber after heating. Utility Model Content

[0035] 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 of 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.

[0036] See also Figure 1 - Figure 6 As shown, a rubber part processing preheating device comprises an annular preheating cylinder 1, and a feed hopper 12 is arranged on the top of the preheating cylinder 1 for adding rubber particles into the preheating cylinder 1;

[0037] The feed hopper 12 is internally connected to a rotating rod 4, and a plurality of limiting plates 41 are arranged in a circular array outside the rotating rod 4. The limiting plates 41 are used to support and rotate the rubber particles added to the feed hopper 12.

[0038] One end of the rotating rod 4 passes through the side wall of the feed hopper 12 and is connected to a second motor 42 fixedly connected to the outside of the feed hopper 12. The second motor 42 can drive the rotating rod 4 to rotate;

[0039] When rubber particles are added into the feed hopper 12, the second motor 42 does not work, and the rotating rod 4 does not rotate, so that the gravity of the added rubber particles does not deflect the limiting plate 41. The limiting plate 41 can support the rubber particles and prevent the rubber particles from being scattered from the bottom of the feed hopper 12.

[0040] One end of the limiting plate 41 is connected to the outer side of the rotating rod 4, and the other end is in contact with the inner wall of the feed hopper 12, and the gap between the two is maintained at 0.3-0.5 cm;

[0041] When the second motor 42 is working, it drives the rotating rod 4 and the limiting plate 41 to rotate. During the rotation, the rubber particles can be evenly added into the preheating cylinder 1. With the movement of the push plate 24, the preheating cylinder 1 can be prevented from being blocked.

[0042] A discharge pipe 13 is provided at the bottom of the preheating cylinder 1, and the discharge pipe 13 is close to the feed hopper 12, and is used to discharge the preheated rubber particles;

[0043] Four supporting columns 11 in a circumferential array are installed at the bottom of the preheating cylinder 1 to support the preheating cylinder 1;

[0044] A heating plate 14 is installed on the inner wall of the preheating cylinder 1 to preheat the plastic particles;

[0045] A plurality of air inlet pipes 3 are arranged in a circumferential array on the outside of the preheating cylinder 1, which are used to spray hot air into the preheating cylinder 1 to stir the rubber particles, thereby enabling the rubber particles to be evenly and fully preheated;

[0046] An annular movable groove 2 is provided in the middle of the inner side of the preheating cylinder 1, an annular sliding rod 22 is provided in the movable groove 2, an annular positioning rod 23 is integrated in the middle of the sliding rod 22, an annular positioning groove 21 is provided in the preheating cylinder 1 corresponding to the position of the positioning rod 23, the positioning rod 23 is rotatably connected in the positioning groove 21, and is used to limit the position of the sliding rod 22 to prevent the sliding rod 22 from shifting;

[0047] A circle of evenly arranged circular push plates 24 are fixed to the outer side of the slide bar 22. The push plates 24 are located in the preheating cylinder 1. The push plates 24 are in contact with the inner wall of the preheating cylinder 1. The gap between the push plates 24 and the inner wall of the preheating cylinder 1 is maintained at 0.1-0.5 cm. The push plates 24 cooperate with the rotation of the slide bar 22 to push the rubber particles inside the preheating cylinder 1, and finally push the preheated rubber particles out of the preheating cylinder 1 from the discharge pipe 13.

[0048] An air outlet 31 is provided in the middle of the push plate 24. The air outlet 31 is used together with the air inlet pipe 3 to allow hot air to flow in the preheating cylinder 1, thereby stirring the rubber particles in different areas.

[0049] A first gear 25 is fixedly connected to the inner side of the slide bar 22, and a second gear 26 is meshed with the inner side of the first gear 25. The first gear 25 cooperates with the second gear 26 to make the slide bar 22 rotate, and then the slide bar 22 drives the push plate 24 to perform a circular motion in the preheating cylinder 1;

[0050] A first motor 27 is connected below the second gear 26, and the first motor 27 is used to drive the second gear 26 to rotate;

[0051] An L-shaped mounting plate 28 is provided below the first motor 27 , and the upper end of the mounting plate 28 is connected to the preheating cylinder 1 . The mounting plate 28 is used to mount and fix the first motor 27 .

[0052] It is worth noting that different types of rubber particles require different preheating times. The speed of the first motor 27 can be adjusted according to the required preheating time so that the rubber particles can be preheated sufficiently in the preheating cylinder 1, and the speed of the second motor 42 should also be adjusted with the adjustment of the first motor 27 to prevent excessive addition of rubber particles, which may cause blockage inside the preheating cylinder 1.
