Description

Technical Field

[0001] The invention relates to the technical field of corn cob screening, and specifically provides a frozen fresh corn cob screening device. Background Art

[0002] Fresh corn cobs are frozen mainly to maintain their freshness, nutritional value and taste, and to extend their shelf life. In order to ensure the quality, safety and satisfaction of the final consumers, corn cobs need to be screened. The main process usually includes checking the size, shape, color, maturity and the presence of any pests or physical damage. Screening is an important quality control measure that can help manufacturers provide consumers with more consistent, safe and high-quality products.

[0003] At present, when corn cobs are screened, the corn cobs are directly poured onto the roller conveyor, which drives the corn cobs for transportation, and the corn cobs are screened by adjusting the spacing between the rotating rollers. However, after the corn cobs are poured onto the roller conveyor, some of the corn cobs are arranged horizontally and vertically with the rotating rollers. During the transportation and screening process, it is difficult for these corn cobs to fall from the corresponding gaps between the rotating rollers. Therefore, the position adjustment and screening accuracy of the corn cobs before screening need to be improved, and when the spacing between the rotating rollers is adjusted from small to medium and large in sequence, it is difficult to achieve automatic adjustment, which reduces the convenience of adjusting and changing the spacing between the rotating rollers, thereby affecting the screening efficiency of the corn cobs. Summary of the invention

[0004] In view of the above problems, an embodiment of the present application provides a frozen fresh corn cob screening device to solve the technical problems in the related art.

The flow dividing plates are located directly below the partition plates, and the two flow dividing plates are arranged in an inverted V shape.

[0012] In a possible implementation manner, the拨动组 (not sure what this exactly is in English, maybe "拨动组件" which can be translated as "拨动 component") includes ear plates installed on the tops of the two support seats. Two sliding plates symmetrically arranged along its width direction are slidably connected between the two ear plates. The lower ends of the sliding plates are installed with uniformly arranged拨板 (not sure what this exactly is in English, maybe "拨片" which can be translated as "flap"). The flaps at the lower ends of the two sliding plates are arranged staggeredly. Plug rods that slide through the funnel box are fixedly installed at both ends of the C-shaped frame. A swinging push-pull plate is hinged between each plug rod and the lower end faces of the two sliding plates.

[0014] In one possible implementation, the conveying drive group includes waist-shaped annular grooves formed on opposite surfaces of two support seats, and mounting grooves are formed on the inner walls of the two arc-shaped sections of the waist-shaped annular grooves. A conveying shaft is rotatably connected between two mounting grooves arranged opposite to each other along the axial direction of the rotating roller. A fixed sleeve on the conveying shaft is provided with sprockets which are symmetrically arranged along its axial direction and located in the corresponding mounting grooves, and the two sprockets in the same waist-shaped annular groove are connected through the same conveying chain transmission.

[0015] In one possible implementation, the pressure adjustment guide rail assembly includes a plurality of No. 1 V-shaped plates and a plurality of No. 2 V-shaped plates and a waist-shaped ring plate installed on the inner wall of the waist-shaped ring groove. The waist-shaped ring plate is located in a horizontal section above the axis of the conveying shaft and is provided with a through groove evenly arranged along the length direction of the waist-shaped ring plate on the side away from the protective cover. The plurality of No. 1 V-shaped plates and the plurality of No. 2 V-shaped plates are installed in the corresponding through grooves in sequence starting from a position close to the protective cover. The distance between the corner of the No. 1 V-shaped plate and the waist-shaped ring plate is smaller than the distance between the corner of the No. 2 V-shaped plate and the waist-shaped ring plate, and the concave surfaces of the No. 1 V-shaped plate and the No. 2 V-shaped plate are both facing the side surface of the end of the rotating roller.

[0017] In a possible implementation, the vibration enhancement assembly includes two rectangular grooves opened on the lower end surface of the screening discharge port and symmetrically arranged along the length direction thereof, and a support spring is installed between the rectangular groove and the inverted V-shaped guide plate.

[0018] The above one or more technical solutions in the embodiments of the present invention have at least one of the following beneficial effects: 1. The present invention realizes the effect of multiple corrections on corn cobs by cooperating with the partition and the toggle group in the correction mechanism, so that the corn cobs are parallel to the rotating rollers when falling on the rotating rollers for screening, so that the corn cobs can accurately fall from the corresponding gap between two adjacent rotating rollers to complete the screening, thereby greatly improving the accuracy of corn cob screening, ensuring the consistency of the corn cob classification and packaging specifications in the later stage, and when the conveying mechanism drives the rotating roller to move, the screening mechanism is adjusted to cooperate with the conveying mechanism to realize the automatic adjustment of the distance between the two adjacent rotating rollers, which not only reduces the driving source when adjusting the distance between the rotating rollers, but also improves the convenience and automation of adjusting the distance between the rotating rollers.

[0019] 2. The two ends of the rotating roller in the present invention move horizontally in a stable manner synchronously under the cooperation of the push spring and the sliding seat, which avoids the rotating roller from tilting during movement and causing the small diameter end of a large corn cob to be stuck between two adjacent rotating rollers and unable to fall off, and also avoids affecting the subsequent resetting of the rotating roller and causing damage to the corn cob.

[0020] 3. The toggle group in the present invention cooperates with the correction drive group to realize the integrated drive of the first correction and the second correction of the corn cob, which reduces the driving source and also improves the convenience of the correction operation.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments 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 creative work are within the scope of protection of the present invention.

[0036] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0037] See also Figure 1 and Figure 7 A frozen fresh corn cob screening device comprises: two support seats 1, a conveying mechanism 2 is commonly arranged between the two support seats 1, the conveying mechanism 2 comprises two conveying chains 20 and a conveying drive group 21 for driving the two conveying chains 20, and the two conveying chains 20 are commonly provided with evenly arranged rotating rollers 22.

[0038] See also Figure 1 , Figure 3 and Figure 7 An adjusting and screening mechanism 3 for adjusting the spacing of multiple rotating rollers 22 is arranged between the two conveying chains 20 and the support seat 1. A protective cover 4 is installed on one side of the two support seats 1 arranged along their length direction. The protective cover 4 is used to prevent the corn cobs from rolling down from the side away from the conveying direction when they fall. The adjusting and screening mechanism 3 is used to adjust the spacing of the rotating rollers 22 from small to large in the process of the conveying chain 20 driving the rotating rollers 22 to move, wherein the adjustment direction is from the protective cover 4 to the other side of the support seat 1 arranged along its length direction.

[0039] See also Figure 1 and Figure 7 A correction mechanism 5 for adjusting the direction of the corn cob is commonly installed on the two support seats 1, and the correction mechanism 5 is located on the side of the support seat 1 close to the protective cover 4; a screening discharge port 7 is opened in the middle of the two support seats 1, and a discharge guide mechanism 6 is commonly installed between the two screening discharge ports 7.

[0040] Pour the frozen fresh corn cobs into the correction mechanism 5. The corn cobs parallel to the rotating roller 22 pass through the correction mechanism 5 directly and fall onto the rotating roller 22. The corn cobs roll between two adjacent rotating rollers 22 by automatic gravity, while the corn cobs not parallel to the rotating roller 22 are stuck in the correction mechanism 5. The correction mechanism 5 adjusts the position of the corn cobs so that the corn cobs are parallel to the rotating roller 22 and fall downward from the correction mechanism 5 onto the rotating roller 22, so as to accurately screen the corn cobs.

[0041] See also Figure 1 and Figure 5The correction mechanism 5 includes a funnel box 51 connected between the tops of the two support seats 1 through a bracket 50. The funnel box 51 consists of two equilateral trapezoidal parts with large-diameter ends facing upward and a rectangular part connected between the equilateral trapezoidal parts. The inner wall of the rectangular part of the funnel box 51 is rotatably installed with two partitions 52 arranged symmetrically along its width direction. The partitions 52 are parallel to the axis of the rotating roller 22. The partitions 52 are rotatably connected between the two inner walls arranged along the length direction of the funnel box 51 through a pin shaft, and the pin shaft is located in the middle of the partition 52 near its upper end. A toggle group 53 is installed on the end face of the funnel box 51 away from the protective cover 4, and a correction drive group 54 for driving the two partitions 52 to swing and the toggle group 53 to move is commonly installed at the lower ends of the two partitions 52.

[0042] The frozen corn cobs are poured into the funnel box 51. The width of the rectangular cavity formed between the two partitions 52 and between the partition 52 and the funnel box 51 is smaller than the length of the corn cobs. At this time, the corn cobs parallel to the rotating roller 22 fall directly downward from the rectangular cavity formed between the two partitions 52 and between the partition 52 and the funnel box 51, while the corn cobs not parallel to the rotating roller 22 are stuck on the top of the partition 52. Then the correction drive group 54 drives the lower end of the partition 52 to move away from the protective cover 4, so that the partition 52 swings along the pin at its upper end. During the swinging of the partition 52, the corn cob stuck on the partition 52 is tilted and enters the rectangular cavity. Then the partition 52 is reset, and the corn cob rotates under the resistance of the rectangular cavity and the inclined side wall at the lower end of the funnel box 51. Since the width of the rectangular cavity formed between the two partitions 52 and between the partition 52 and the funnel box 51 is smaller than the length of the corn cob, the corn cob is pushed down and can be rotated to a state parallel to the rotating roller 22, so that the corn cob falls between two adjacent rotating rollers 22 when it falls downward.

[0043] When the correction drive group 54 drives the partition 52 to rotate and swing, the correction drive group 54 synchronously drives the toggle group 53 to work, and the toggle group 53 corrects the few uncorrected corn cobs that were missed during the falling process, ensuring that each corn cob is in a state parallel to the rotating roller 22 before screening, so as to accurately screen the corn cobs.

[0044] In summary, by cooperating with the toggle group 53 and the correction drive group 54, the first correction and the second correction of the corn cob are integrated into one drive, which reduces the driving source and improves the convenience of the correction operation.

[0045] See also Figure 1 and Figure 5, the correction drive group 54 includes a C-shaped frame 541 and guide grooves 540 opened on both vertical inner walls of the funnel box 51 arranged along its length direction. Both ends of the C-shaped frame 541 slide through the side wall of the funnel box 51 and then slide into the corresponding guide grooves 540. The longitudinal horizontal section of the C-shaped frame 541 is located outside the funnel box 51, and a drive source is installed between the C-shaped frame 541 and the outer wall of the funnel box 51. The lower end of the partition plate 52 is provided with a guide groove extending along its length direction and penetrating through. A driving rod 542 is slidably connected in the guide groove, and the driving rod 542 is rotatably connected between the two transverse horizontal sections of the C-shaped frame 541.

[0046] When the drive source (such as a cylinder) drives the C-shaped frame 541 to move, the C-shaped frame 541 pushes the lower end of the partition plate 52 through the driving rod 542, causing the partition plate 52 to rotate around the pin shaft it is connected to. During this process, the driving rod 542 slides along the guide groove.

[0047] Refer to Figure 5 , both ends of the upper end of the partition plate 52 are arc-shaped structures. The arc-shaped structure at the top of the partition plate 52 is used to reduce the contact area between it and the corn cob, so as to reduce the friction between the corn cob stuck horizontally on the partition plate 52 and the partition plate 52 when the partition plate 52 swings and tilts and drops. The arc-shaped structure at the lower end of the partition plate 52 can reduce the degree of scraping damage to the corn cob caused by the swing of the partition plate 52.

[0048] Refer to Figure 5 , two flow dividing plates 510 arranged symmetrically along the width direction are installed between the two inner walls of the funnel box 51 arranged along its length direction. The flow dividing plates 510 are located directly below the partition plate 52, and the two flow dividing plates 510 are arranged in an inverted V shape. The space between the two flow dividing plates 510 and the cooperation between the flow dividing plates 510 and the inner wall of the funnel box 51 limit the corn cobs, so as to prevent the partition plate 52 from turning horizontally again when it swings and drops downward.

[0049] Refer to Figure 1 、 Figure 5 And Figure 6 , the拨动组53 includes ear plates 530 installed on the tops of both supports 1. Two sliding plates 531 arranged symmetrically along the width direction are slidably connected between the two ear plates 530. The lower ends of the sliding plates 531 are installed with uniformly arranged dial plates 532. The dial plates 532 at the lower ends of the two sliding plates 531 are arranged staggeredly. Plug rods 533 that slide through the funnel box 51 are fixedly installed at both ends of the C-shaped frame 541. A swinging push-pull plate 534 is hinged between each plug rod 533 and the lower end surfaces of the two sliding plates 531.

[0050] In the process of reciprocating along the width direction of the funnel box 51, the shaped frame 541 drives the insertion rod 533 to reciprocate, and the insertion rod 533 drives the two sliding plates 531 to move back and forth in an interlaced manner by swinging the push-pull plate 534, so that the two sliding plates 531 drive the paddle plate 532 to move back and forth in an interlaced manner along the axial direction of the rotating roller 22. When the paddle plate 532 encounters a corn cob lying on the rotating roller 22 during its movement, the paddle plates 532 on the two sliding plates 531 are in contact with the corn cob. The corn cob is pushed by the staggered paddles 532 to rotate and fall into the gap between two adjacent rotating rollers 22, and the corn cob is parallel to the rotating rollers 22. At the same time, after the corn cob falls into the gap between two adjacent rotating rollers 22, the top of the corn cob is separated from the paddles 532, so that a few uncorrected corn cobs missed during the falling process can be corrected again, ensuring that each corn cob is parallel to the rotating roller 22 before screening, so as to accurately screen the corn cobs.

[0051] See also Figure 1 , Figure 3 , Figure 4 , Fig. 9 and Fig.10 The adjusting and screening mechanism 3 includes a plurality of L-shaped supporting seats 30 installed on the conveying chain 20 and arranged evenly, a spring groove is opened in the vertical section of the L-shaped supporting seat 30, a sliding seat 31 is slidably connected in the spring groove, the sliding seat 31 is connected to the spring groove by a push spring 32, the rotating roller 22 is rotatably connected between two sliding seats 31 arranged and opposite to each other along the width direction of the support seat 1, an L-shaped supplementary plate 33 is installed on the end surface of the horizontal section of the L-shaped supporting seat 30 away from the relative rotating roller 22, the vertical section of the L-shaped supplementary plate 33 is horizontally slidably connected with an insert rod 34, a swing rod 35 is hinged between the insert rod 34 and the sliding seat 31, and a pressure adjustment guide rail assembly 36 is provided on the support seat 1, which cooperates with the adjacent plurality of insert rods 34 to drive the sliding seat 31 to move, and the pressure adjustment guide rail assembly 36 cooperates with the insert rod 34 to drive the rotating roller 22 to move horizontally back and forth for spacing adjustment.

[0052] See also Figure 7 and Figure 8 The conveying drive group 21 includes waist-shaped annular grooves 210 formed on opposite surfaces of two support seats 1, and mounting grooves 211 are formed on the inner walls of the two arc-shaped segments of the waist-shaped annular grooves 210. A conveying shaft 212 is rotatably connected between two mounting grooves 211 arranged opposite to each other along the axial direction of the rotating roller 22. A sprocket 213 is fixedly sleeved on the conveying shaft 212 and is symmetrically arranged along its axial direction and located in the corresponding mounting grooves 211. The two sprockets 213 in the same waist-shaped annular groove 210 are connected through the same conveying chain 20.

[0053] The corn cob is supported by two adjacent rotating rollers 22, and then the conveying shaft 212 rotates through the sprocket 213 to drive the conveying chain 20 and the rotating roller 22 to move away from the protective cover 4, thereby driving the corn cob to move, so that the corn cob only rubs against the rotating roller 22 when it falls during screening, which greatly reduces the damage to the corn kernels on the corn cob and improves the quality of the corn cob when screening.

[0054] See also Figure 4 , Fig. 9 , Fig.10 and Fig.11 The pressure regulating guide rail assembly 36 includes a plurality of No. 1 V-shaped plates 360 and a plurality of No. 2 V-shaped plates 361 and a waist-shaped ring plate 362 installed on the inner wall of the waist-shaped ring groove 210. The waist-shaped ring plate 362 is located in a horizontal section above the axis of the conveying shaft 212 and is away from the protective cover 4. A through groove evenly arranged along the length direction of the waist-shaped ring plate 362 is opened. The plurality of No. 1 V-shaped plates 360 and the plurality of No. 2 V-shaped plates 361 are installed in the corresponding through grooves in sequence starting from a position close to the protective cover 4. The distance between the corner of the No. 1 V-shaped plate 360 ​​and the waist-shaped ring plate 362 is smaller than the distance between the corner of the No. 2 V-shaped plate 361 and the waist-shaped ring plate 362. The concave surfaces of the No. 1 V-shaped plate 360 ​​and the No. 2 V-shaped plate 361 are both facing the side surface of the end of the rotating roller 22.

[0055] When the distance between two adjacent rotating rollers 22 does not change, the corn cobs screened are called small corn cobs, and this area is also called a small screening area; when the insert rod 34 at the end of the rotating roller 22 located on the side of the moving direction of the conveying chain 20 of the two adjacent rotating rollers 22 abuts against the No. 1 V-shaped plate 360, the distance between the two adjacent rotating rollers 22 changes for the first time and the corn cobs screened are called medium-sized corn cobs, and this area is also called a medium-sized screening area; when the insert rod 34 at the end of the rotating roller 22 located on the side of the moving direction of the two adjacent rotating rollers 22 abuts against the No. 2 V-shaped plate 361, the distance between the two adjacent rotating rollers 22 changes again and the corn cobs screened are called large corn cobs, and this area is also called a large screening area.

[0056] When the corn cob falls between two adjacent rotating rollers 22 in the small screening area after passing through the correction mechanism 5, if the diameter of the corn cob is smaller than the distance between the two adjacent rotating rollers 22, it will directly fall down from between the two adjacent rotating rollers 22, while the corn cob with a diameter larger than the distance between the two adjacent rotating rollers 22 at this time will stay on the rotating roller 22, and the conveying drive group 21 drives the rotating roller 22 and the corn cob to move through the conveying chain 20. During the movement, the toggle group 53 can also block the corn cobs stacked together when falling, so that the corn cobs all fall between the two adjacent rotating rollers 22 in a horizontal state, avoiding the obstruction of stacking between the corn cobs and affecting the screening of the corn cobs.

[0057] When the corn cob enters the medium-sized screening area, the insertion rods 34 at both ends of one of the two adjacent rotating rollers 22 below the corn cob, which is located on the side of the moving direction of the conveying chain 20, move along the waist-shaped ring plate 362 toward the No. 1 V-shaped plate 360. During this process, the push spring 32 is in a compressed state. When the insertion rod 34 is aligned with the through groove and the No. 1 V-shaped plate 360, the push spring 32 pushes the sliding seat 31 to move in the moving direction of the conveying chain 20 through the rebound force, thereby changing the distance between the two adjacent rotating rollers 22 at the lower end of the corn cob. If the size of the corn cob is smaller than the size between the two adjacent rotating rollers 22 at this time, it will directly move downward. The corn cobs are screened and the rotating rollers 22 below the corn cobs move horizontally under the cooperation of the push springs 32 at both ends and the sliding seat 31, which prevents the rotating rollers 22 from tilting during movement, causing the small diameter end of the large corn cob to be stuck between two adjacent rotating rollers 22 and unable to fall, affecting the subsequent resetting of the rotating rollers 22 and causing damage to the corn cobs. When the abutting rod 34 is pressed against the corner of the No. 1 V-shaped plate 360 ​​and continues to move, the abutting rod 34 pushes the sliding seat 31 to move and squeezes the push spring 32 to contract through the swing rod 35 under the action of the push pressure given by the inclined surface of the No. 1 V-shaped plate 360, thereby driving the rotating roller 22 to resetting.

[0058] When the conveying drive group 21 drives the corn cobs into the large screening area through the conveying chain 20, the movement mode of the rotating roller 22 at the lower end of the corn cobs is the same as that when entering the medium screening area. The difference is that the insert rod 34 abuts against the second V-shaped plate 361, and the distance between two adjacent rotating rollers 22 is further changed. The distance between the two rotating rollers 22 is larger than the distance in the previous medium screening area, thereby realizing the screening of large corn cobs.

[0059] To sum up, in the process of screening corn cobs, the adjustment screening mechanism 3 can not only accurately screen and classify corn cobs of different volumes, but also prevent the corn cobs from being damaged during the screening process, thereby greatly improving the screening quality of the corn cobs and protecting the corn cobs from damage.

[0060] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 7 and Fig.12The discharge guide mechanism 6 includes an inverted V-shaped guide plate 60 installed between two screening discharge ports 7 and sliding up and down, a vibration enhancement component 61 is installed between the lower end surface of the inverted V-shaped guide plate 60 and the two screening discharge ports 7, and two inverted V-shaped partition bars 62 evenly arranged along its length direction are installed on the top of the inverted V-shaped guide plate 60. The two inverted V-shaped partition bars 62 divide the inverted V-shaped guide plate 60 into three areas to separate the corn cobs of different sizes after screening, and a side guide plate 63 is commonly installed at one end of the two support seats 1 away from the protective cover 4.

[0061] The inverted V-shaped guide plate 60 is used to receive and guide the corn cobs that fall after screening. Two inverted V-shaped partition bars 62 divide the inverted V-shaped guide plate 60 into three areas, which correspond to the small screening area, the medium screening area, and the large screening area, respectively, so that the small, medium and large-sized corn cobs that are screened can be separated after they fall after screening. The corn cobs with larger volumes that are difficult to screen will fall onto the side guide plate 63 when they move to the end of the support seat 1. The side guide plate 63 guides the corn cobs of this size.

[0062] See also Figure 2 and Figure 7 The vibration-enhancing component 61 includes two rectangular grooves 610 symmetrically arranged along the length direction of the screening discharge port 7, and a support spring 611 is installed between the rectangular groove 610 and the inverted V-shaped guide plate 60. When the corn cob falls on the inverted V-shaped guide plate 60, the impact force of the corn cob's own weight on the inverted V-shaped guide plate 60 causes the inverted V-shaped guide plate 60 and the support spring 611 to vibrate up and down, which not only buffers the fall of the corn cob and prevents the corn cob from being damaged, but also enables the corn cob that falls on the inverted V-shaped guide plate 60 to quickly fall downward from the inverted V-shaped guide plate 60 and be discharged under the action of the vibration force.

[0063] See also Figure 1-Figure 12 When working, the frozen fresh corn cobs are poured into the correction mechanism 5, and the corn cobs parallel to the rotating roller 22 directly pass through the correction mechanism 5 and fall on the rotating roller 22. The corn cobs are rolled between two adjacent rotating rollers 22 by automatic gravity, while the corn cobs not parallel to the rotating roller 22 are stuck in the correction mechanism 5. The correction mechanism 5 adjusts the position of the corn cobs so that the corn cobs are parallel to the rotating roller 22 and fall downward from the correction mechanism 5 onto the rotating roller 22, so as to accurately screen the corn cobs.

[0064] When the corn cob passes through the correction mechanism 5 and falls between two adjacent rotating rollers 22 in the small screening area, the adjusting screening mechanism 3 adjusts the distance between the two adjacent rotating rollers 22 receiving the corn cob from small to large in sequence, thereby realizing screening and classification of corn cobs of different sizes.

[0065] To sum up, in the process of screening corn cobs, the adjustment screening mechanism 3 can not only accurately screen and classify corn cobs of different volumes, but also prevent the corn cobs from being damaged during the screening process, thereby greatly improving the screening quality of the corn cobs and protecting the corn cobs from damage.
