Description

Technical Field

[0001] The utility model relates to the technical field of corn peeling rollers, and in particular to a wear-resistant and low-temperature-resistant corn peeling roller. Background Art

[0002] Corn husking rollers are a key component in corn processing, used to remove the outer husks. Typically, the corn passes through the rotating rollers, peeling the outer husks off, revealing the kernels. These rollers are typically made of wear-resistant materials to ensure a long service life and efficient husking. In corn processing, the rollers are a critical component for ensuring smooth production line operation.

[0003] However, existing corn peeling rollers can face challenges in low-temperature environments, especially in northern winters with sub-zero temperatures. Low temperatures can cause the material to become brittle, making the peeling rollers more susceptible to cracking or breaking. This embrittlement can seriously impact the roller's lifespan and peeling performance. Utility Model Content

[0004] The utility model proposes a wear-resistant and low-temperature resistant corn peeling roller, which solves the problem in the related technology that the corn peeling roller will become brittle in a low-temperature environment, making the corn peeling roller prone to cracks or breakage, thereby affecting the service life and peeling effect of the peeling roller.

[0005] The technical solution of the utility model is as follows:

[0006] A wear-resistant and low-temperature-resistant corn peeling roller comprises a roller body, a peeling structure is fixedly connected to the surface of the roller body, a connecting shaft is fixedly connected to the middle of both ends of the roller body, and a heating structure is fixedly connected to the middle of the roller body, and the heating structure extends from one end of the roller body to the other end;

[0007] The heating structure includes a heating plate, the cross section of which is a circular ring structure. The heating plate is fixedly connected to a plurality of fixing protrusions, which extend from the outer surface of the heating plate to the outer surface of the roller body. The cross section of the fixing protrusion is a "U"-shaped structure.

[0008] Furthermore, both ends of the heating plate are fixedly connected with interface protrusions for connecting to a power source, and the cross-section of the interface protrusion is annular around the connection axis.

[0009] Furthermore, the peeling structure includes a plurality of rectangular protrusion groups and a plurality of spiral peeling protrusions, and the rectangular protrusion groups and the spiral peeling protrusions extend from the two ends of the roller body to the middle of the roller body respectively, and the plurality of rectangular protrusion groups and the plurality of spiral peeling protrusions are arranged in a circle around the roller body, and adjacent rectangular protrusion groups are staggered with each other. The rectangular protrusion group includes a plurality of rectangular peeling protrusions, and the rectangular peeling protrusions are arranged linearly along the roller body from one end of the roller body to the middle of the roller body. The protrusion height of the rectangular peeling protrusions in the same group decreases as the distance from the middle of the roller body decreases.

[0010] Furthermore, the roller body is divided into a wear-resistant layer, a first supporting layer, and a second supporting layer from the outside to the inside, and the heating structure is located between the first supporting layer and the second supporting layer.

[0011] The working principle and beneficial effects of the utility model are as follows:

[0012] The utility model heats the roller body through the heating structure in the middle of the roller body, thereby increasing the overall temperature of the roller body, reducing the possibility of embrittlement in a low-temperature environment, and thus increasing its service life in a low-temperature environment. It solves the problem in the related technology that the corn machine peeling roller will become brittle in a low-temperature environment, making the corn machine peeling roller prone to cracks or breakage, thereby affecting the service life and peeling effect of the peeling roller.

[0019] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] like Figures 1 to 4 As shown, this embodiment proposes a wear-resistant and low-temperature resistant corn peeling roller, comprising a roller body 1, a peeling structure fixedly connected to the surface of the roller body 1, a connecting shaft 15 fixedly connected to the middle of both ends of the roller body 1, and a heating structure fixedly connected to the middle of the roller body 1, the heating structure extending from one end of the roller body 1 to the other end. The connecting shaft 15 is the shaft connecting the roller body 1 to the motor and is also the shaft connecting the roller body 1 to the corn peeling roller. The heating structure extends from one end of the roller body 1 to the other end, that is, the heating structure covers the entire length of the roller body 1, rather than being limited to a portion of the roller body 1. This ensures that the entire roller body 1 can be heated during processing, thereby improving the adaptability to low-temperature environments and ensuring uniform heating of the peeling roller in low-temperature environments.

[0021] In this embodiment, the roller body 1 is divided, from the outside to the inside, into a wear-resistant layer 10, a first support layer 11, and a second support layer 12. The heating structure is located between the first support layer 11 and the second support layer 12. The wear-resistant layer 10 is the outermost layer of the roller body 1. It is primarily used to withstand friction with the corn husk, protect the roller body 1 structure, and extend its service life. The wear-resistant layer 10 can be made of wear-resistant and low-temperature-resistant materials such as polytetrafluoroethylene (PTFE) and polyethylene (PE). The first and second support layers 11 and 12 both provide support for the wear-resistant layer 10 and the entire roller body 1 structure, enabling them to withstand the pressure and loads encountered during processing. Both the first and second support layers 11 and 12 can be made of high-strength materials such as stainless steel, carbon steel, and aluminum alloy.

[0022] In this embodiment, the heating structure includes a heating plate 2, which has a circular cross-section. One or more resistance wires are installed inside the heating plate 2. When current passes through the resistance wires, a resistance heating effect is generated, converting electrical energy into thermal energy, thereby heating the surface of the heating plate 2. The heat on the surface of the heating plate 2 is then transferred to other structures of the roller body 1 through heat transfer, thereby heating the entire roller body 1. The heating plate 2 has the advantages of simplicity, strong controllability, and fast response speed. The cross-section of the heating plate 2 is a circular structure, which can provide uniform heating distribution, thereby ensuring uniform heating of the entire roller body 1. Heating the entire roller body 1 by the heating plate 2 not only prevents material embrittlement, but also solves the problem of water vapor freezing on the surface of the roller body 1, which affects the peeling effect and causes difficulty in machine operation. It also solves the problem of lubricating materials such as lubricating oil on the connecting shaft 15 becoming viscous or solidified due to low temperatures, resulting in insufficient lubrication, poor operation of the roller body 1, or increased friction.

[0023] In this embodiment, the heating plate 2 is fixedly connected to a plurality of fixing protrusions 20. The fixing protrusions 20 extend from the outer surface of the heating plate 2 to the outer surface of the roller body 1, and the cross-section of the fixing protrusions 20 has a "U"-shaped structure. The fixing protrusions 20 are used to ensure the connection between the heating plate 2 and the first support layer 11. Since the cross-section of the heating plate 2 has a circular ring structure, it is possible that the connection with the first support layer 11 will be disconnected when the roller body 1 rotates, and then it will become a rotational connection, resulting in the roller body 1 being unable to rotate effectively. The addition of the fixing protrusions 20 can avoid this situation. Moreover, the extension of the fixing protrusions 20 toward the outer surface of the roller body 1 can further accelerate the transfer of heat from the heating plate 2 to the surface of the roller body 1. The cross section of the fixing protrusion 20 is a "U"-shaped structure, which can solve the problem of unstable fixation of the second supporting layer 12 located inside the heating plate 2 and the heating plate 2. Since the fixing protrusion 20 extends toward the outer surface of the roller body 1, it cannot ensure a stable connection between the heating plate 2 and the second supporting layer 12. By setting the cross section of the fixing protrusion 20 to a "U"-shaped structure, a corresponding protrusion that can be embedded in this "U"-shaped structure can be set on the second supporting layer 12 to achieve a stable connection between it and the heating layer.

[0024] In this embodiment, both ends of the heating plate 2 are fixedly connected to an interface protrusion 21 for connecting to a power source. The cross-section of the interface protrusion 21 is annular around the connecting shaft 15. The interface protrusion 21 is used to connect the heating plate 2 to the power source. The positive and negative poles of the power source can be arranged at the connection between the corn grinder and the two connecting shafts 15 and abut against the outer surface of the interface protrusion 21. Since the interface protrusion 21 is arranged around the connecting shaft 15, the roller body 1 can be continuously connected to the positive and negative poles of the power source during rotation, so that the heating plate 2 can be used even when the roller body 1 is in operation.

[0025] In this embodiment, the peeling structure includes a plurality of rectangular protrusion groups and a plurality of spiral peeling protrusions 14, which extend from both ends of the roller body 1 to the middle of the roller body 1 respectively. The plurality of rectangular protrusion groups and the plurality of spiral peeling protrusions 14 are arranged in a circular pattern around the roller body 1, and adjacent rectangular protrusion groups are staggered with each other. The rectangular protrusion group includes a plurality of rectangular peeling protrusions 13, which are arranged linearly along the roller body 1 from one end of the roller body 1 to the middle of the roller body 1. The protrusion height of the rectangular peeling protrusions 13 in the same group decreases as the distance from the middle of the roller body 1 decreases. The rectangular protrusion group and the spiral peeling protrusion 14 are both used to peel corn. The rectangular protrusion group contacts the corn first relative to the spiral peeling protrusion 14, and the rectangular protrusion group first peels the corn husk. The rectangular peeling protrusion 13 in the rectangular protrusion group can quickly separate the corn husk from the inner pulp of the corn, and then completely peel part of the husk. After the corn husk is separated from the inner pulp, the spiral peeling protrusion 14 can quickly roll off the corn husk, thereby completely separating all the corn husks on the corn from the corn body, achieving the function of corn peeling. Adjacent rectangular protrusion groups are staggered, which can cause the rectangular peeling protrusions 13 in adjacent rectangular protrusion groups to stagger with each other, which can increase the contact area between the rectangular protrusion group and the corn husk, thereby increasing its efficiency. The height of the rectangular peeling protrusions 13 of the same group decreases as the distance from the middle of the roller body 1 decreases, so that the height of the rectangular peeling protrusions 13 is arranged from high to bottom, which can effectively reduce the friction and damage to the corn pulp during the peeling process, reduce losses, ensure the integrity of the corn pulp, and make the peeled corn more beautiful.

[0026] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
