Description

Technical Field

[0001] The utility model relates to the technical field of rice husker rubber rollers, in particular to a rice husker rubber roller capable of dissipating heat. Background Art

[0002] Rice husker is a grain processing machine that removes the husk of rice and makes brown rice. It can remove the outer shell of rice, reduce the cracking of rice grains and the damage of the skin, and keep the brown rice intact as much as possible. Common rice husker equipment includes rubber roller rice husker, sand plate rice husker and centrifugal rice husker. The main working parts of the rubber roller rice husker are a pair of horizontal rubber rollers or plastic rollers bonded or covered with rubber layers on the cast iron cylinder. The axes of the two rollers are located in the same horizontal plane or with a slight height difference. The two rollers rotate in opposite directions at a speed of 2.5-3.2 m / s, and the sum of the linear speeds should not exceed 30 m / s. The rice is fed evenly between the two rollers over the entire length of the rubber roller through the flow plate (or through the feeding roller and the flow plate). The equal-diameter rollers rotate in the opposite direction at different linear speeds, and the pressure of the pressure weight causes the rice passing through the rollers to be squeezed and torn. Due to the squeezing of the two rollers and the rubbing and tearing effect caused by the speed difference of the two rollers, most of the rice is husked.

[0003] Long-term friction between the rubber roller and rice will cause the temperature of the rubber roller itself to be too high. Due to the influence of the rubber material, high temperature can easily reduce the hardness of the rubber, resulting in rapid wear of the rubber roller. Frequent replacement is required, which increases the investment cost of production and processing. In view of this, we propose a rice husking rubber roller that can dissipate heat. Utility Model Content

[0012] Preferably, the card frame is in an inverted T shape.

[0013] Preferably, the hollow frame is movably connected to the roller via a clamping frame.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0024] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0025] Embodiment 1: A heat dissipating rice husking rubber roller, see Figures 1 to 3 , comprising a rice husker casing 1, a group of rubber roller assemblies 2 are arranged inside the rice husker casing 1, a group of auxiliary mechanisms 3 are symmetrically arranged on the end surface of the rubber roller assembly 2, an air inlet pipe 4 is arranged on the top of the auxiliary mechanism 3 on the left side of the rubber roller assembly 2, and an air outlet pipe 5 is arranged on the top of the auxiliary mechanism 3 on the right side of the rubber roller assembly 2;

[0026] The rubber roller assembly 2 includes a roller 201, wherein an air inlet pipe 4, an auxiliary mechanism 3, the roller 201, and an air outlet pipe 5 form a fluid channel, a plurality of limit grooves are evenly provided on the surface of the roller 201, and a heat conducting plate 202 is matched and engaged inside the limit grooves. It is worth noting that the heat conducting plate 202 is made of a copper-aluminum mixed material, one side of the heat conducting plate 202 extends to the inside of the roller 201, and the heat conducting plate 202 is linear. A rubber roller 203 is matched and sleeved on the surface of the roller 201, and an axle rod 204 passes through the middle end of the roller 201, and the axle rod 204 is connected to the roller 201 through a limit frame 205, and a plurality of slow flow grooves 206 are distributed at annular intervals on the inner wall of the roller 201. The utility model effectively conducts the heat generated by the friction between the rubber cylinder 203 and the rice through the linear heat conductive plate 202, so that the heat on the rubber cylinder 203 is quickly conducted to the linear heat conductive plate 202, and the external cold air enters the roller 201 through the air inlet pipe 4 and the left auxiliary mechanism 3, and effectively exchanges heat with the heat on the linear heat conductive plate 202, takes away the heat on the linear heat conductive plate 202, realizes the heat dissipation of the rubber cylinder 203, and delays the loss of the rubber cylinder 203. The airflow after the heat exchange is discharged through the right auxiliary mechanism 3 and the air outlet pipe 5. Since a plurality of slow flow grooves 206 are distributed at annular intervals on the inner wall of the roller 201, the transmission speed of the cold air in the roller 201 is effectively reduced, so that the cold air and the heat on the linear heat conductive plate 202 can be more fully exchanged, the heat exchange efficiency is improved, and thus the heat dissipation effect of the rubber cylinder 203 is improved.

[0027] It is worth mentioning that the auxiliary mechanism 3 includes a hollow frame 301, the hollow frame 301 is sleeved on the surface of the shaft 204, and a clamping frame 302 is fixedly connected to the side of the hollow frame 301. Further, the clamping frame 302 is in an inverted T shape, and the clamping frame 302 is clamped on the inner side of the end of the roller 201. Further, the hollow frame 301 is movably engaged with the roller 201 through the clamping frame 302. In the utility model, since the hollow frame 301 is movably engaged with the roller 201 through the clamping frame 302, when the roller 201 rotates with the rotation of the shaft 204, the hollow frame 301 can still maintain its original shape and be sleeved on the surface of the shaft 204, and is not affected by the rotation of the shaft 204 and the roller 201.

[0028] Embodiment 2: A heat dissipating rice husking rubber roller, see Figure 1 , Figure 3 and Figure 4 , comprising a rice husker casing 1, a group of rubber roller assemblies 2 are arranged inside the rice husker casing 1, a group of auxiliary mechanisms 3 are symmetrically arranged on the end surface of the rubber roller assembly 2, an air inlet pipe 4 is arranged on the top of the auxiliary mechanism 3 on the left side of the rubber roller assembly 2, and an air outlet pipe 5 is arranged on the top of the auxiliary mechanism 3 on the right side of the rubber roller assembly 2;

[0029] The rubber roller assembly 2 includes a roller 201, wherein a fluid channel is formed between the air inlet pipe 4, the auxiliary mechanism 3, the roller 201, and the air outlet pipe 5. A plurality of limit grooves are evenly provided on the surface of the roller 201, and a heat conducting plate 202 is matched and engaged inside the limit groove. It is worth noting that the heat conducting plate 202 is made of a copper-aluminum mixed material, and one side of the heat conducting plate 202 extends to the inside of the roller 201. The heat conducting plate 202 is curved, and the peak lines and valley lines of adjacent heat conducting plates 202 intersect. A rubber roller 203 is matched and sleeved on the surface of the roller 201. A shaft rod 204 passes through the middle end of the roller 201, and the shaft rod 204 is connected to the roller 201 through a limit frame 205. A plurality of slow flow grooves 206 are distributed at annular intervals on the inner wall of the roller 201. The utility model effectively conducts the heat generated by the friction between the rubber tube 203 and the rice through the curved heat conducting plate 202. The curved heat conducting plate 202 increases the heat conducting surface and improves the heat conducting efficiency. At the same time, the curved heat conducting plate 202 can extend the transmission path of the cold air, slow down the transmission speed of the cold air, and improve the heat dissipation effect of the rubber tube 203. Since the outer extension part of the curved heat conducting plate 202 extends to the inner side of the rubber tube 203, the rubber tube 203 is guided and positioned, and the stability of the rubber tube 203 is improved. When the rubber tube 203 is torn from the rice, the curved heat conducting plate 202 effectively disperses the pulling stress of the rubber tube 203. At the same time, since the peak lines and valley lines of adjacent curved heat conducting plates 202 intersect, the stresses between adjacent curved heat conducting plates 202 can be offset accordingly, thereby reducing the wrinkles generated when the rubber tube 203 is torn from the rice.

[0030] It is worth mentioning that the auxiliary mechanism 3 includes a hollow frame 301, which is sleeved on the surface of the shaft 204, and a clamping frame 302 is fixedly connected to the side of the hollow frame 301. Furthermore, the clamping frame 302 is in an inverted T shape, and the clamping frame 302 is clamped on the inner side of the end of the roller 201. Furthermore, the hollow frame 301 is movably engaged with the roller 201 through the clamping frame 302.

[0031] Working principle: The driving device drives the shaft 204 to rotate, so that a group of rubber roller assemblies 2 rotate towards each other, squeeze and tear the rice, and at the same time connect the air inlet pipe 4 to the external cooling fan. During the rice husking process, the heat conducting plate 202 conducts the heat generated by the friction between the rubber cylinder 203 and the rice, so that the heat on the rubber cylinder 203 is quickly conducted to the heat conducting plate 202, and the external cold air enters the roller 201 through the air inlet pipe 4 and the left auxiliary mechanism 3, exchanges heat with the heat on the heat conducting plate 202, and takes away the heat on the heat conducting plate 202, thereby dissipating the heat of the rubber cylinder 203 and delaying the loss of the rubber cylinder 203. The airflow after heat exchange is discharged through the right auxiliary mechanism 3 and the air outlet pipe 5.

However, as long as they do not deviate from the spirit of the present invention, they are all within the protection scope of the present invention.
