Description

Technical Field

[0001] The invention relates to the technical field of corn processing equipment, and in particular discloses a corn cob peeling machine with a size screening function. Background Art

[0002] In corn deep processing enterprises, the purchased corn cobs need to go through multiple processes such as peeling, threshing, germ removal, and grinding. There are usually two ways to peel the corn cobs: manual peeling and mechanical peeling. Although manual peeling has good peeling effect and less damage to corn, it has low processing efficiency and has been gradually eliminated. Mechanical peeling uses the squeezing and kneading effect between the rubber roller and the conveyor roller in the peeling machine to remove the surface skin of the corn cob.

[0003] The utility model patent with application number CN219352398U discloses a fully automatic fresh corn peeling machine, including a peeling machine body, a feed inlet, and a collecting cover; the collecting cover is a funnel-shaped shell structure, and the collecting cover is fixedly installed below the peeling machine body by bolts; the crushing box is fixedly arranged below the collecting cover; the corn husk discharge port is arranged at the lower part of the crushing box, and the splint is fitted on the outer walls on both sides of the corn husk discharge port; the lower part of the articulated frame is welded to the outer wall of the splint, and the upper part of the articulated frame is articulated to the outer wall of the corn husk discharge port; the upper end of the cylinder is articulated to the outer wall of the crushing box, and the lower end of the cylinder is articulated to the articulated frame. The corn husking machine disclosed in the patent uses the action of the husking roller to realize the husking process during operation, but there are problems of incomplete husking or partial threshing during the husking process. This is because the corn cobs are of different sizes, and the roller gap between the husking roller and the conveying roller remains unchanged. Some thicker corn cobs will be incompletely husked, while some thinner corn cobs will be squeezed and threshed. Therefore, in view of the above-mentioned shortcomings of the existing corn husking machine, the present application proposes a method of first screening the corn cobs by size, and then placing the screened corn cobs in roller-type husking mechanisms with different roller gaps for husking, so as to ensure that the corn cobs are completely husked and avoid the problem of partial threshing due to squeezing during the husking process. Summary of the invention

[0004] The present invention aims to provide a corn cob peeling machine with a size screening function, so that in the process of peeling the corn cobs, the corn cobs are first screened according to the thickness and size, and then peeled in a roller peeling mechanism entering different roller gaps to ensure the peeling effect of the corn cobs.

[0005] The present invention is achieved through the following technical solutions: A corn cob peeling machine with size screening function comprises a chassis, a peeling mechanism is arranged inside the chassis, a screening and unloading mechanism is arranged above the peeling mechanism, and a feeding and conveying mechanism for conveying corn cobs one by one to the screening and unloading mechanism is arranged at the right end of the chassis; The peeling mechanism comprises a plurality of peeling and conveying combination rollers arranged at intervals on the left and right, and the roller gaps of the plurality of peeling and conveying combination rollers are gradually increased from right to left, and a power device for driving all the peeling and conveying combination rollers to operate synchronously is arranged at the front end of the chassis; The screening and unloading mechanism includes two rail bars arranged parallel to each other in front and back, and a moving bar seat is slidably arranged on the two rail bars. A driving component is arranged at the rear end of the chassis to drive the moving bar seat to move left and right along the rail bars. A strip slide is opened in the moving bar seat, and the left and right ends of the strip slide are connected to sliders through springs, and a roller is rotatably connected between the two sliders aligned front and back, and electromagnets that can generate repulsive force are installed on the opposite sides of the two sliders at the front end, and a carbon brush assembly connected to the electromagnet is arranged with an upper and lower interval on the front end surfaces of the two sliders, and a horizontal bar frame parallel to the rail bars is fixed in the chassis, and a plurality of groups of copper bars that are aligned up and down with corresponding peeling and conveying combination rollers and act on the carbon brush assembly are arranged on the horizontal bar frame, and each group of the copper bars is connected to a DC power supply through wires, and the voltage of multiple DC currents is gradually increased from right to left.

[0006] As a further configuration of the above scheme, a plurality of strip-shaped sliding openings are provided on the movable strip seat at intervals, and two adjacent strip-shaped sliding openings are separated by a partition plate connected between the two movable strip seats.

[0007] As a further configuration of the above solution, the driving assembly is any one of a belt transmission mechanism or a screw transmission mechanism.

[0008] As a further configuration of the above scheme, the peeling and conveying combination roller includes two roller rods arranged side by side, and the front and rear ends of the roller rods are installed inside the chassis through bearing seats, one of the roller rods is provided with a rubber roller, and the other roller rod is provided with a threaded roller, and the two roller rods are driven by circular gear meshing.

[0009] As a further configuration of the above solution, a spacer is provided between two adjacent groups of the peeling and conveying combined rollers.

[0010] As a further configuration of the above scheme, the feeding and conveying mechanism includes a vertical conveying box arranged on the right side of the chassis, belt rollers are arranged at the upper and lower ends of the vertical conveying box, and the end of one of the belt rollers is connected to the first motor, a conveyor belt is arranged between the two belt rollers, and a plurality of supporting plates are arranged at equal intervals on the conveyor belt, the lower right end of the vertical conveying box is connected to the chassis, and the upper left end of the vertical conveying box is connected to the chassis, and a material guide plate connected to the screening and unloading mechanism is arranged on the inner wall of the chassis.

[0011] As a further configuration of the above scheme, a discharge guide groove is provided in the chassis directly below the peeling mechanism, the guide groove being inclined downward and extending out from the right side of the chassis.

[0012] As a further configuration of the above solution, a partition bar is provided in the discharge guide groove, and the partition bar is located directly below the front ends of the rubber roller and the threaded roller.

[0013] During operation of the corn cob peeling machine disclosed in the present invention, the corn cobs are transported upward one by one by the feeding and conveying mechanism, and then dropped from the upper right end of the chassis into between two rollers in the screening and unloading mechanism. At this time, the roller gap between the two rollers is the smallest, and the corn cobs cannot fall through the roller gap.

[0014] Next, the moving bar seat is transported from right to left under the action of the driving assembly, and when the moving bar seat passes directly above each set of peeling and conveying combination rollers from right to left, the electromagnet circuit is connected through the contact between the carbon brush assembly and the copper bar, thereby generating a repulsive force and overcoming the spring resistance to make the two rollers move in opposite directions, so that the roller gap between the two rollers becomes larger, and the corn cobs pass through the roller gap between the two rollers and fall onto the corresponding peeling and conveying combination rollers. During the movement of the moving bar seat, the voltage of the DC power supply connected to different copper bars gradually increases, so that when the roller gap between the two rollers passes over the corresponding peeling and conveying combination rollers from right to left in sequence, the roller gap between the two rollers will become larger and larger, so that corn cobs of different thicknesses fall onto the corresponding peeling and conveying combination rollers for peeling.

[0015] When the corn cob falls onto the peeling and conveying combination roller, the rubber roller and the threaded roller in the peeling and conveying combination roller will rotate synchronously in opposite directions. The rubber roller uses the friction provided by the surface texture to forcibly peel off the cortex of the corn cob, while the threaded roller provides axial conveying force to the corn cob, making the corn cob move forward, thereby completing the separation of the corn cob and the cortex, completing the peeling process, and finally discharged from the chassis through the discharge guide groove.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The corn cob peeling machine disclosed in the present invention can receive the corn cobs discharged into the machine box by the screening and unloading mechanism when peeling the corn cobs, and then can control the roller gap size between two rollers during movement to allow the corn cobs to pass through the roller gap and fall onto the peeling and conveying combination roller of the corresponding roller gap size for peeling, thereby realizing size screening of the corn cobs before peeling, and then using the peeling and conveying combination roller of the specific roller gap for processing according to the screening results, which effectively ensures the peeling effect of the corn cobs and reduces the local threshing phenomenon occurring during the corn cob peeling process.

[0017] The adjustment of the roller gap in the screening and unloading mechanism of the present invention adopts the method of electromagnet + different voltage circuits, and then combines the carbon brush assembly and the copper bar conductivity to realize the on and off of the electromagnet circuit. The roller gap between the two rollers can be adjusted to the corresponding size when above different peeling and conveying combination rollers to realize the passage of corn cobs. The structural design is novel and ingenious, and there is no need to additionally set up sensors and controllers to realize the control and adjustment of the roller gap size. The overall design is relatively simple and the actual use effect is excellent. BRIEF DESCRIPTION OF THE DRAWINGS

A feeding belt 205 is arranged between the upper and lower belt rollers 203, and a plurality of supporting plates 206 are arranged at equal intervals on the feeding belt 205. During the operation of the feeding conveying mechanism 2, the corn cobs in the feeding hopper 202 can be picked up one by one by the supporting plates 206, and then moved from bottom to top. When the supporting plates 206 are turned over at the top with the feeding belt 205, the picked corn cobs can be discharged into the chassis 1.

[0024] Reference Figure 5 , Attachment Figure 6 and attached Figure 7The screening and unloading mechanism 3 includes two rail bars 301 arranged parallel to each other and fixed in the chassis 1. A moving bar seat 302 is slidably arranged on the two rail bars 301. The front and rear moving bar seats 302 are divided into a plurality of material receiving areas by a plurality of partitions 305. At the same time, a driving assembly 303 for driving the moving bar seat 302 to move left and right is also arranged in the chassis 1 at the rear side of the rail bar 301. The specific driving assembly 303 can be any of a transmission belt or a screw drive. The driving assembly 303 in the present embodiment 1 is in the form of a transmission belt, which connects the rear moving bar seat 302 with the transmission belt, and can achieve precise control through the power input of the servo motor.

[0025] A plurality of strip-shaped sliding openings 304 are arranged in intervals in each movable bar seat 302, and each strip-shaped sliding opening 304 corresponds to a material receiving area divided by a partition 305. Then, sliders 306 are arranged at both ends of the strip-shaped sliding opening 304 for limited sliding movement, and springs 307 are connected between the sliders 306 and the end walls of the strip-shaped sliding opening 304, so that the two sliders 306 in the same strip-shaped sliding opening 304 maintain a constant interval without external force. Then, a roller 308 is arranged to rotate between the two sliders 306 aligned front and back, and the roller gap between the two rollers 308 can support the thinnest corn cob to prevent it from falling from the roller gap. Electromagnets 309 are installed on the opposite sides of a pair of sliders 306 at the front end, and the two electromagnets 309 can generate a mutually repelling force after being connected to the same circuit. Then, carbon brush assemblies 310 arranged at intervals up and down are arranged on the front side of the slider 306, and the two carbon brush assemblies 310 are connected to the positive and negative poles of the corresponding electromagnets 309. A horizontal bar frame 311 parallel to the track bar 301 is fixed in the chassis 1 on the front side of the movable bar seat 302, and a plurality of groups of copper bars 312 are arranged at intervals in the middle position of the side of the horizontal bar frame 311 facing the slider 306. Each group of copper bars 312 is spaced apart from each other and interacts with the carbon brush assembly 310 on the slider 306. Then each group of copper bars 312 is electrically connected to a DC power supply 313 with different voltages through a wire, and the voltages of the plurality of DC currents 313 are gradually increased from right to left.

[0026] Reference Figure 2 , Attachment Figure 3 and attached Figure 4The peeling mechanism 4 includes a plurality of peeling and conveying combination rollers 400 arranged at intervals on the left and right. Each group of peeling and conveying combination rollers 400 is arranged directly below the middle section of the corresponding copper strip 312, and the roller gaps of the plurality of peeling and conveying combination rollers 400 are arranged to be larger from right to left, and two adjacent groups of peeling and conveying combination rollers 400 are separated by a spacer 407. Specifically, the peeling and conveying combination roller 400 includes two roller rods 401 arranged side by side, and the front and rear ends of the roller rods 401 are rotatably mounted inside the chassis 1 through bearing seats 402. A rubber roller 403 with peeling patterns is arranged on the left roller rod 401, and a threaded roller 404 for pushing the peeled corn cobs forward is arranged on the right roller rod 401. A circular gear 405 is arranged at the front end of each roller rod 401 extending out of the chassis 1, and the circular gears 405 on the same group of roller rods 401 are meshed with each other, and finally a power device 406 for driving all peeling and conveying combined rollers 400 to run synchronously is arranged on the front side of the chassis 1. The specific power device 406 can be a belt or a shaft rod + bevel gear transmission form.

[0027] Finally, the discharge guide 5 is arranged directly below the multiple groups of peeling and conveying combined rollers 400, and is arranged to be inclined with the right end high and the left side low, and its lower inclined section extends out of the chassis 1. In addition, a partition bar 500 is arranged in the discharge guide 5, and the partition bar 500 is located directly below the front end of the rubber roller 403 and the threaded roller 404, so that the discharge guide 5 on the rear side of the partition bar 500 is used to discharge the peeled corn cob husk, and the discharge guide 5 on the front side of the partition bar 500 is used to discharge the peeled corn cob.

[0028] The specific operation steps and working principle of the corn cob peeling machine disclosed in this embodiment 1 are as follows: The corn cobs to be peeled are placed in the feeding hopper 202, and then the first motor 204 drives the feeding belt 205. During the transmission process, the corn cobs are picked up one by one through the supporting plate 206, and the corn is put into the chassis 1 during the top flipping process, and then rolled downward along the guide plate 6 arranged on the side wall of the chassis 1. At this time, the two rollers 308 located under the guide plate 6 receive the corn cobs transported one by one. After the reception is completed, the driving component 303 is started to make the moving bar seat 302 move to the left along the track bar 301.

[0029] When the movable bar seat 302 moves to the top of the first group of peeling and conveying combined rollers 400, the carbon brush assembly 310 on the corresponding pair of sliders 306 contacts the first pair of copper bars 312, thereby connecting the circuits of the two corresponding electromagnets 309, thereby generating a repulsive force between the two. Since the voltage of the DC power supply 313 connected to the first pair of copper bars 312 is relatively small, the repulsive force generated by the two electromagnets 309 will cause the two rollers 308 to overcome the force of the spring 307 and expand the roller gap by about 2 cm. At this time, the thinner corn cobs can pass through the roller gap and fall onto the corresponding peeling and conveying combination roller 400; if the corn cobs are thicker, they cannot pass through the roller gap, and when moving to the top of the first group of peeling and conveying combination rollers 400, the voltage will increase and the repulsive force will become stronger, which will cause the roller gap between the two rollers 308 to expand to about 3 cm. If the diameter of the corn cob is smaller than the roller gap at this time, it will fall in; if it is larger, it will enter the top of the last group of peeling and conveying combination rollers 400 and fall down after the roller gap between the two rollers 308 expands to the maximum.

[0030] When the corn cob falls onto the corresponding peeling and conveying combination roller 400, the rubber roller 403 and the threaded roller 404 move in opposite directions synchronously. The rubber roller 403 peels off the surface cortex of the corn cob through the texture on the surface, and the threaded roller 404 pushes the corn cob forward until the surface cortex of the corn cob is separated from the corn cob. The separated cortex and corn cob can be discharged from the chassis 1 in partitions through the discharge guide groove 5.

[0031] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
