Description

TECHNICAL FIELD

[0001] The utility model relates to corn cob peeling technical field, and specifically is a corn cob peeling machine. BACKGROUND

[0002] In the production and processing process of corn cob, the corn cob needs to be peeled (shelled), and the traditional manual peeling is time-consuming and laborious.

[0003] A corn peeling machine is disclosed in Chinese patent application No. CN201220542380.8, which comprises a rack, a motor and a peeling bin are installed on the rack, the peeling bin is provided with a feeding hopper at one end and a discharging port at the other end, two parallel peeling rubber rollers with fish-scale-shaped protrusions on the surface are rotatably installed in the peeling bin, two parallel guide rollers are arranged between the two peeling rubber rollers, the two guide rollers are each provided with a spiral-shaped guide rib, the output shaft of the motor is connected in transmission with the peeling rubber rollers and the guide rollers through a belt, and a baffle plate is hinged above the peeling rubber rollers and the guide rollers in the peeling bin. The husk of the corn is rolled into the space between the adjacent peeling rubber rollers and guide rollers under the action of the peeling rubber rollers and the cooperating guide rollers, and then is torn off under the action of friction and other forces, thereby improving the peeling efficiency and reducing the labor intensity.

[0004] Since the corn husk is peeled off by the friction between the peeling rubber rollers and the cooperating guide rollers, the size of the cooperation gap between the peeling rubber rollers and the cooperating guide rollers will affect the peeling effect of the corn cob. In order to adjust the gap between the two according to the actual situation, a corn peeling machine chain transmission peeling mechanism is disclosed in Chinese patent application No. CN201810169941.6, which discloses that the roller seat of the floating roller (relative to the peeling rubber roller) is set in a floating form, a compression spring assembly is arranged at one end of the roller seat, and the distance between the peeling rubber roller and the guide roller can be adjusted by adjusting the compression spring assembly, thereby adjusting the cooperation gap between the two.

[0005] In the actual corn cob peeling process, because the corn cob has more husks in the initial stage of peeling, and the surface layer of the husk is relatively thick, and the husk is relatively loose between the husks, the husk will be more wrapped between the peeling rubber roller and the guide roller. In order to control the mechanical load and ensure the normal work of the machine, a larger gap needs to be set between the peeling rubber roller and the guide roller. In the later stage of peeling, because the husk attached to the surface of the corn cob is less and thinner, and the attachment is more tight, the husk will be less wrapped between the peeling rubber roller and the guide roller. In order to ensure the peeling effect, a smaller gap is set between the peeling rubber roller and the guide roller. The existing corn cob peeling machine has an integral peeling rubber roller. Although the structure of the existing peeling machine can adjust the gap size between the peeling rubber roller and the guide roller, it can only adjust the peeling rubber roller in parallel, and cannot flexibly adjust the matching distance between the peeling rubber roller and the guide roller in different stages according to the actual peeling process. In the use process, it is not convenient to control the mechanical load, and it is also difficult to ensure the peeling effect. Practical new type content

DETAILED DESCRIPTION

[0028] The utility model is further explained below in combination with the drawings and examples.

[0029] As Figure 1 , Figure 2 shown, a corn cob peeling machine of the utility model, including peeling bin 1 and install at least one group of peeling assembly 2 in the peeling bin 1. The one end of peeling bin 1 is equipped with feed hopper 11, and the other end is equipped with discharge port 12. The peeling assembly 2 includes peeling guide roller 21 and is arranged at least two sections of peeling roller 22 with the same side of the peeling guide roller 21 and along the axis direction of the peeling guide roller 21 in sequence to cooperate with the peeling guide roller 21 and peel. The peeling roller 22 is installed on the bearing seat 23 that rotates with it, so that it can rotate around its axis. The bearing seat 23 can be movably arranged along the direction close to or away from the peeling guide roller 21, so that the distance between the peeling roller 22 and the peeling guide roller 21 can be adjusted respectively. The side of the bearing seat 23 is respectively equipped with adjusting mechanism 3 for adjusting the distance between the peeling roller 22 and the peeling guide roller 21. The peeling guide roller 21 is provided with a material guide structure for feeding to the discharge port direction of the peeling bin 1.

[0030] The specific number of peeling guide roller 21 is set according to the number of stages of peeling corn. In the embodiment of the utility model, only two sections of peeling roller 22 are arranged on one side of the peeling guide roller 21, that is, the peeling process of corn is only divided into two stages. In some embodiments, three sections of peeling roller 22 are arranged on one side of the peeling guide roller 21 to divide the peeling process of corn into three stages. In some embodiments, four sections of peeling roller 22 are arranged on one side of the peeling guide roller 21 to divide the peeling process of corn into four stages.

[0031] The specific number of peeling assembly 2 can be set according to the need. The more the peeling assembly 2, the higher the efficiency of the peeling machine, and the greater the yield. In the embodiment of the utility model, three groups of peeling assembly 2 are arranged in the peeling bin 1.

[0032] When the corn cob peeling machine of the utility model works, the upper surface of the peeling guide roller 21 is rotated to the direction close to the peeling roller 22 by the driving mechanism. Specifically, Figure 3As shown, if the peeling roller 22 is located at the left side of the peeling guide roller 21, the upper surface of the peeling guide roller 21 is counterclockwise to the rotation direction close to the peeling roller 22, and vice versa, if the peeling roller 22 is located at the right side of the peeling guide roller 21, it is counterclockwise. When peeling, the corn cob enters the peeling bin 1 through the feed hopper 11 of the peeling bin 1, and the corn cob after entering can rotate under the friction of the peeling guide roller 21 and can roll the skin into the gap between the peeling guide roller 21 and the peeling roller 22, and the peeling roller 22 can rotate under the friction of the corn cob. The corn skin is rolled into the gap between the peeling guide roller 21 and the peeling roller 22, and can be torn off by the friction of the peeling guide roller 21 and the peeling roller 22, and at the same time, since the peeling guide roller 21 is provided with a material guiding structure for feeding to the discharge port of the peeling bin 1, the peeling guide roller 21 can not only provide the peeling friction for the corn cob to rotate during rotation, but also gradually push the corn cob to the discharge port of the peeling bin 1, so that the peeled corn cob can be pushed out of the discharge port of the peeling bin 1.

[0033] The corn cob peeling machine of the utility model is provided with at least two sections of peeling rollers 22 on the same side of the peeling guide roller 21, and each section of the peeling roller 22 is installed on the bearing seat 23 matched with rotation, the bearing seat 23 is movably arranged along the direction close to or away from the peeling guide roller 21, and the side of the bearing seat 23 is provided with an adjusting mechanism 3 for adjusting the distance between the peeling roller 22 and the peeling guide roller 21, that is, the existing integral peeling roller is arranged into multiple sections of independently adjustable gap sections, so that the position of each section of the bearing seat 23 can be adjusted through the adjusting mechanism, the distance between each section of the peeling roller 22 and the peeling guide roller 21 can be adjusted, and the gap between each section of the peeling roller 22 and the peeling guide roller 21 can be adjusted to meet the different requirements of the gap between the peeling roller 22 and the peeling guide roller 21 in different peeling stages. For example, a section of the peeling roller 22 in the initial peeling stage, because the corn skin is more rolled into the gap between the peeling roller and the peeling guide roller, in order to prevent mechanical jamming or excessive load, the gap between the peeling roller and the peeling guide roller in this section can be adjusted to be larger, and the peeling roller in the subsequent stage, because the corn skin is gradually reduced, the corn skin is gradually less rolled into the gap between the corresponding peeling roller and the peeling guide roller, in order to better peel, the gap between each peeling roller and the peeling guide roller in the subsequent stage can be gradually adjusted to be smaller. Therefore, the peeling machine is more convenient to use, and the peeling effect of the corn cob and the mechanical load can be better guaranteed.

[0034] As shown in the embodiment of the utility model, the material guiding structure is a plurality of inclined plates 213 arranged on the peeling guide roller 21. Figure 4 As shown in the embodiment of the utility model, the material guiding structure is a plurality of inclined plates 213 arranged on the peeling guide roller 21. Figure 2As shown, the material guiding structure in the embodiment of the utility model is same with the existing peeling guide roller material guiding structure, which is a spiral rib 211 arranged on the surface of the peeling guide roller 21 and extending spirally along the axis direction of the peeling guide roller 21. Figure 2 As shown, in the embodiment of the utility model, two spiral ribs are arranged on the peeling guide roller 21, the peeling guide roller 21 is divided into two section parts along the length direction, the spiral rib with smaller spiral angle is arranged in the front section part, the spiral rib with larger spiral angle is arranged in the rear section part, and the spiral rib in the rear section part is arranged in larger number and higher density in the circumferential direction, so as to reduce the possibility that the corn cob is extruded by the spiral rib or the corn kernel is knocked off by the spiral rib in the later period.

[0035] In order to further increase the peeling effect, the peeling guide roller 21 is further provided with a protrusion 212 between the adjacent two threads of the spiral rib 211.

[0036] During the corn cob peeling process, with the gradual reduction of the corn skin, the surface of the corn cob is also smoother, the friction force received by the corn cob is also smaller, and the friction force of the corn cob on the peeling roller is also gradually reduced, therefore, the friction force received by the peeling roller arranged at the rear (close to the discharge port direction of the peeling bin) is smaller, and the torque received by the peeling roller is also smaller, and the friction force received by the peeling roller arranged at the front (close to the feed hopper direction of the peeling bin) is larger, and the torque received by the peeling roller is also larger. Figure 5 As shown, in order to further ensure the peeling effect, in the utility model, further, the head and tail of the adjacent two section parts of the peeling roller 22 are connected through the flexible transmission structure 4. After the head and tail of the adjacent two section parts of the peeling roller 22 are connected through the flexible transmission structure, the section parts of the peeling roller 22 can be driven and transmitted through the flexible transmission structure, and the torque of the peeling roller 22 arranged at the front can be distributed to the peeling roller 22 arranged at the rear and receiving smaller torque, so that the section parts of the peeling roller 22 arranged at the rear are driven to rotate actively by the peeling roller 22 arranged at the front, the peeling friction force received by the subsequent corn cob is increased, and thus the peeling effect can be improved.

[0037] The flexible transmission structure can be a flexible shaft, a universal coupling, a universal joint coupling, a cross universal coupling, etc.

[0038] In the embodiment of the utility model, the flexible transmission structure is a cross universal coupling.

[0039] Each section of the peeling roller 22 can be provided with one or more bearing seats. Generally, in order to better support the peeling roller 22 and make the peeling roller 22 bear force better, two bearing seats respectively independently provided at two ends of each section of the peeling roller 22 can be rotationally matched with the peeling roller 22. As shown in Figure 2 and Figure 5 When the flexible transmission structure is provided, one end of the two adjacent peeling rollers 22 can not be provided with a bearing seat (the flexible transmission structure can generate certain constraint on the end not provided with the bearing seat). In this way, the two adjacent peeling rollers 22 only need to be provided with three bearing seats, which takes into account the mechanical manufacturing cost and the force borne by the peeling roller, and also reduces the transition distance between the two adjacent sections of the peeling roller 22, thereby facilitating the transition of the corn cob.

[0040] In the utility model, preferably, the bearing seat 23 is internally provided with a self-aligning bearing rotationally matched with the corresponding peeling guide roller 21. After the self-aligning bearing is adopted, the distance between the two ends of each section of the peeling roller and the peeling guide roller 21 can be inconsistent, for example, the distance between one end of the peeling roller and the gap of the other section is gradually reduced, and the gap adjustment is more flexible.

[0041] Specifically, the bearing seat 23 can be movably arranged in a linear sliding manner along the direction close to or away from the peeling guide roller 21. As shown in Figure 2 In the utility model embodiment, the bearing seat 23 is swingably arranged in the direction close to or away from the peeling guide roller 21 through the hinge shaft 24 provided at the lower end of the bearing seat 23 and rotationally connected with the shell of the peeling bin 1. That is, the bearing seat 23 can swing in the direction close to or away from the peeling guide roller 21 around the hinge shaft 24, and the bearing seat 23 is swingably arranged. In order to make the bearing seat 23 swing in the direction close to or away from the peeling guide roller 21 around the hinge shaft 24, it can be understood that the axis of the hinge shaft 24 is parallel to the axis of the peeling guide roller 21.

[0042] In some embodiments, the adjusting mechanism 3 adopts an adjusting screw. As shown in Figure 6As shown, the adjusting mechanism 3 includes an adjusting screw 31 installed on one side of the corresponding bearing seat 23 for pushing the bearing seat 23 to move in the direction of approaching the peeling guide roller 21, and one end of the adjusting screw 31 close to the bearing seat 23 is provided with a compression spring 32 which is connected with the bearing seat 23 and can be compressed. When it is needed to adjust the gap between the peeling roller 22 and the peeling guide roller 21, the corresponding adjusting screw 31 of the peeling roller bearing seat 23 is screwed, so that the adjusting screw 31 moves in the direction of approaching the peeling guide roller 21, and the bearing seat 23 is pushed to move in the direction of approaching the peeling guide roller 21 by the compression spring 32, so that the gap is reduced; if it is needed to increase the gap, the adjusting screw 31 is screwed in the reverse direction. The above structure is provided with the compression spring 32 at one end of the adjusting screw 31, the compression spring can be compressed, and the gap between the peeling guide roller 21 and the peeling roller 22 can be adaptively adjusted within a certain range according to the actual amount of corn pieces. In some embodiments, the compression spring 32 also adopts a tension spring.

[0043] In the utility model, the peeling guide roller 21 generally adopts an iron roller or a steel roller. The peeling roller 22 can adopt an iron roller, a steel roller or a rubber roller, and preferably adopts a rubber roller. The rubber roller has low cost and certain deformation capacity, and has higher friction coefficient, which is more conducive to peeling of the corn cob. In order to further increase the friction coefficient of the rubber roller, the surface of the rubber roller can be provided with protrusions.

[0044] In the utility model, in order to further improve the peeling effect, as shown, Figure 7 As shown, the upper portion of the peeling assembly 2 is provided with a pressing plate 5 which is gradually inclined downward along the direction of the discharge port of the peeling bin 1, the front end (one end close to the peeling bin feeding hopper) of the pressing plate 5 is hinged to the shell of the peeling bin 1 through a horizontal shaft 7, so that the rear end (one end close to the peeling bin discharge port) of the pressing plate 5 can rotate up and down around the horizontal shaft 7, and the upper portion of the pressing plate 5 is provided with a pressing spring 6 which prevents the rear end of the pressing plate 5 from rotating upward. The pressing plate can be one or more, and in the utility model embodiment, the pressing plate is two. When the corn cob passes through the pressing plate, the pressing plate can provide a certain pressure to the corn cob, so that the contact between the corn cob and the peeling assembly is better, and the friction force is larger, thereby being conducive to peeling. The front end of the pressing plate 5 is hinged, the upper portion is provided with the pressing spring 6, and the rear end of the pressing plate 5 can swing upward by adaptively compressing the pressing spring 6 according to the size of the corn cob, and can be adjusted according to the diameter of the corn cob, so as to facilitate the corn cob to pass through.
