Description

Technical Field

[0001] The utility model relates to the technical field of preheating devices, in particular to a preheating device. Background Art

[0002] Rubber is the basic raw material of the rubber industry and is widely used in the manufacture of tires, hoses, tapes, cables and other rubber products. The vulcanization temperature of rubber is around 165-175 degrees at the feed inlet. If the machine is turned on directly for production, the product will be difficult to form, so the preheating temperature must reach the requirement before production can begin.

[0003] The traditional rubber preheating process is to directly put the rubber particles into the heating chamber for heating. Due to the inconsistency of the rubber particles, the heating state inside the rubber is different, which easily leads to partial melting of the rubber while the rest of the rubber is still in an unheated state. In addition, the traditional heating equipment has a relatively simple structure and can only heat the rubber at a fixed position but cannot adjust the internal rubber particles, resulting in uneven heating of the internal and external rubber particles and easily causing the rubber particles to solidify into blocks, making them difficult to export. Therefore, a preheating device is needed to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] Preferably, a discharge pipe is connected to the bottom end of the cylinder, the bottom end of the inner wall of the insulation cylinder is an inclined surface, and a discharge square pipe end is arranged on the right side of the insulation cylinder. The inclined surface design of the bottom end of the inner wall of the insulation cylinder can facilitate the guidance of the heated and melted rubber.

[0008] Preferably, the stirring assembly includes a sub-gear, the shaft end of the sub-gear passes through the top cover and is connected to a rotating shaft, and two blades are symmetrically connected to the outer side of the bottom end of the rotating shaft, and the blades can be driven to rotate by the rotating shaft, thereby facilitating the stirring operation of the rubber particles.

[0009] Preferably, two scrapers are symmetrically connected at the center of the rotating shaft, and the scraper is in a T-shaped structure as a whole. The outer side of the scraper contacts the inner wall of the insulation cylinder. When the rotating shaft rotates, the scraper can be driven to rotate synchronously, so that the scraper can scrape the inner wall of the cylinder.

[0010] Preferably, the side of the secondary gear is meshed with a main gear through teeth, and the main gear is rotatably mounted on the surface of the top cover. The top of the main gear is connected to a drive motor. The rotational torque of the drive motor can be increased by designing different outer diameters of the main gear and the secondary gear.

[0011] Preferably, a protective support plate is sleeved and installed on the outer side of the main gear and the auxiliary gear, and the protective support plate is fixed to the surface of the top cover.

[0013] The utility model has at least the following beneficial effects:

[0014] 1. By setting a preheating component, the insulation preheating operation in the heating cylinder is realized. Compared with the traditional structure, the device heats the inner wall of the cylinder by setting a cylinder inside the insulation cylinder, setting a heating chamber on the inner wall of the cylinder, and installing a heating pipe in the heating chamber. After the temperature in the heating chamber rises, the hot air is guided to the inner cavity of the cylinder through the heat guide tank, and then the gas in the inner cavity of the cylinder is preheated, which makes it convenient for the rubber particles to quickly heat up and melt when entering the cylinder, thereby shortening the melting time of the rubber particles.

[0015] 2. By setting up a stirring component, the uniform heating of the rubber particles is ensured. The device drives the main gear to rotate through the output end of the driving motor. The main gear and the sub-gear cooperate with each other to drive the rotating shaft to rotate. The rotating shaft can drive the scraper and the blade to rotate during rotation, and then the rubber particles inside the cylinder can be stroked so that the rubber particles can be evenly stressed. At the same time, the scraper can scrape the rubber particles that stick to the inner wall of the cylinder after heating to prevent affecting the heating effect of the rubber particles inside the cylinder.

[0024] The bottom end of the cylinder 151 is connected with a discharge pipe 152 . The bottom end of the inner wall of the heat preservation cylinder 11 is an inclined surface. A discharge square pipe end is arranged on the right side of the heat preservation cylinder 11 .

[0025] The stirring assembly 2 includes a pinion gear 23 . The shaft end of the pinion gear 23 passes through the top cover 12 and is connected to a rotating shaft 24 . Two blades 26 are symmetrically connected to the outer side of the bottom end of the rotating shaft 24 .

[0026] Two scrapers 25 are symmetrically connected at the center of the rotating shaft 24 . The scrapers 25 are in a T-shaped structure as a whole, and the outer sides of the scrapers 25 are in contact with the inner wall of the heat preservation tube 11 .

[0027] The side of the secondary gear 23 is meshed with the main gear 22 through teeth, and the main gear 22 is rotatably mounted on the surface of the top cover 12 , and the top of the main gear 22 is connected to the driving motor 21 .

[0029] The heat introduction tank 154 is composed of hard pipe ends at both ends and a telescopic pipe end in the middle.

[0030] The inclined surface design at the bottom end of the inner wall of the heat-insulating cylinder 11 can facilitate the guidance of the heated and melted rubber, so that the rubber can be discharged through the discharge square tube end for easy collection. At the same time, the cavity between the heat-insulating cylinder 11 and the cylinder body 151 can be insulated to a certain extent to avoid solidification during discharge. When the rotating shaft 24 rotates, the rotating shaft 24 can drive the blade 26 to rotate, which makes it convenient to stir the rubber particles and ensure the uniformity of the rubber particles when heated, so as to avoid the rubber particles inside and outside from being uniformly heated and solidified into blocks.

[0031] Working principle: According to the attached Figure 1 With attached Figure 3As shown, during use, the heating tube 153 can be started to heat and increase the temperature of the inner wall of the cylinder 151.

At this time, the top cover 12 is buckled on the top of the heat preservation cylinder 11, and the plug plate 13 is inserted into the slot on the side of the heat preservation cylinder 11. At the same time, the locking bolt 14 is inserted into the through hole of the plug plate 13 to lock and fix it;

[0032] Secondly, according to the attached Figure 2 With attached Figure 4 As shown, when the preheating in the cylinder 151 is completed, the rubber particles can be put in from the feed port 16, so that the rubber particles enter the interior of the heating cylinder 15. At this time, the drive motor 21 can be started at the same time, so that the output end of the drive motor 21 drives the main gear 22 to rotate, the main gear 22 can drive the sub-gear 23 to rotate, the sub-gear 23 can drive the shaft 24 to rotate, and the shaft 24 drives the scraper 25 and the blade 26 to cooperate to stir the rubber particles, thereby ensuring that the rubber particles are evenly heated.
