Description

Technical Field

[0001] The invention relates to the technical field of food processing, and in particular to an auxiliary feeding device for frying bean products. Background Art

[0002] Before being fried and shaped, granular bean products usually need to be transported to the frying box through a conveyor line. However, when the granular bean products are being transported, the beans piled on the surface of the line are prone to surface adhesion due to high air humidity or incomplete drainage. The granular bean products that stick to each other will not only be heated unevenly after being put into the frying box, affecting the quality of the finished product, but also easily clump and take shape, which adds a breaking step for subsequent processing and reduces production efficiency.

[0003] Therefore, in the prior art, a conveyor chain with mesh holes is often used to convey granular soy products. The piles of soy products on the conveyor chain are flattened by a spreading plate, so that the beans enter the mesh holes to form an independent load, thereby conveying each bean individually to avoid the problem of beans sticking together.

[0004] However, in actual operation, due to the large number of mesh holes and the wide coverage, the sweeping of the spreading plate often cannot accurately push the soy products into each mesh hole, which can easily cause some bean granules to stack between two mesh holes and overlap on two beans, making the effect of conveying the beans one by one poor and there is still a risk of mutual adhesion.

DETAILED DESCRIPTION

[0036] 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.

[0037] like Figures 1 to 10 As shown, the present invention provides a bean frying auxiliary feeding device, including a frame 1 and a bent cover 5, the frame 1 is fixedly installed on the ground foundation, a conveyor belt 2 is installed on the frame 1 for looping and transportation, the conveyor belt 2 is driven by an external motor for rotation and transportation, a plurality of grooves 3 for carrying the beans are provided on the conveyor belt 2, the grooves 3 are arranged along the outer contour of the conveyor belt 2, the plurality of grooves 3 are arranged at fixed intervals along the width direction of the conveyor belt 2, a temporary storage rail 4 is formed between two adjacent grooves 3, and the temporary storage rail 4 is the surface of the conveyor belt 2.

[0038] like Figure 1 , 2As shown, the bending baffle 5 is fixedly installed above the conveyor belt 2 through the mounting bracket 6. The mounting bracket 6 includes a main bracket installed on the ground foundation and a sub-bracket arranged on the side of the conveyor belt 2. The bending baffle 5 includes a side plate 7. The side plate 7 is connected to the sub-bracket through a joint and is arranged on both sides of the conveyor belt 2. The ends of the pre-leveling baffle 8 and the arranging baffle 9 are both installed on the side plate 7. Specifically, the side plate 7 is correspondingly arranged on the sides of the grooves 3 on the two outer sides of the conveyor belt 2 to limit the beans and prevent the beans on the conveyor belt 2 from deviating to both sides. Among them, the side plate 7 is fixedly suspended above the conveyor belt 2. That is, there is a small gap between its bottom surface and the surface of the conveyor belt 2. In the traditional belt for conveying beans, the side bands on both sides for limiting the beans thereon are usually formed integrally with the belt, and in order to facilitate the belt to rotate at the tail position, the side bands on both sides are usually set as elastic bending skirts. In this device, the elastic bending skirt cannot maintain a straight line, so it is impossible to limit the beans arranged in a straight line. However, the side band arranged in a straight line is difficult to rotate when passing the tail of the belt. Therefore, the device chooses to use a conveyor belt 2 without a side band, and the side band for limiting the bean grains is set as the side plate 7 in the device. The side plate 7 is designed to have no contact with the conveyor belt 2, so that the side plate 7 can not only limit the position of the bean grains, but also does not restrict the rotation of the conveyor belt 2 at the tail.

[0039] At the same time, a pre-leveling baffle 8 and an arranging baffle 9 are arranged between the two side plates 7, wherein the pre-leveling baffle 8 is arranged parallel to the conveyor belt 2 at the upstream position of the conveyor belt 2, and there is a gap between the pre-leveling baffle 8 and the upper surface of the conveyor belt 2 that can only pass a single bean.

[0040] like Figure 1 , 2 As shown in Figure 3, the arranging baffle 9 is arranged perpendicular to the conveying belt 2 and at the downstream position of the conveying belt 2. The bottom surface of the arranging baffle 9 is arranged close to the surface of the temporary storage rail 4. A plurality of feeding gaps are opened at the bottom of the arranging baffle 9. The feeding gaps are arranged just above the groove 3, and the height and width of the feeding gaps can only pass a single bean grain. A guide rail assembly 16 is arranged on the surface of the arranging baffle 9 facing the pre-leveling baffle 8.

[0041] The length of the side plate 7 is consistent with the length of the conveyor belt 2 to ensure the limiting effect of the whole process of conveying the beans. The pre-leveling baffle 8 and the arrangement baffle 9 can be connected through a bracket, and the side plate 7 is enclosed to form a cover body and is covered on the conveyor belt 2. The pre-leveling baffle 8 is used to preliminarily flatten the beans transported from the upstream, so that the beans piled on the conveyor belt 2 can be transported in a single layer after passing through the pre-leveling baffle 8, so as to facilitate the subsequent division of the beans into a single arc slot 11.

[0042] In addition, a shallow groove can be further provided on the temporary storage rail 4, so that after the short-amplitude vibrator 12 vibrates, the beans are distributed in the shallow groove on the temporary storage rail 4, making it more convenient to enter the feeding belt 17 later. After the pre-leveling baffle 8 preliminarily flattens the piled beans, the beans will be distributed in the shallow groove between the groove 3 and the adjacent groove 3 (i.e., the temporary storage rail 4). Further, a plurality of arc slots 11 are linearly provided on the side of the groove 3 along the length direction of the groove 3, each arc slot 11 can only hold one bean, and the arc slots 11 on the adjacent two grooves 3 are staggered. At the same time, a short-amplitude vibrator 12 is provided on the side of the conveyor belt 2, and the working end of the short-amplitude vibrator 12 is connected to the conveyor belt 2 through a dispersion bracket 13 for driving the conveyor belt 2 to vibrate longitudinally. The working end of the short-amplitude vibrator 12 on the conveyor belt 2 has an action area including the bottom of the pre-leveling baffle 8 and the bottom of the pre-leveling baffle 8 away from the side of the arrangement baffle 9.

[0043] like Figure 2As shown, in the specific working process, when the piles of beans are put down onto the conveyor belt 2, the conveyor belt 2 is first vibrated by the short-amplitude vibrator 12, and the vibration area is below the pre-leveling baffle 8 and below the side of the pre-leveling baffle 8 close to the upstream position. At this time, the beans can be shaken apart in the process of being transported to the pre-leveling baffle 8. On the one hand, when the conveyor belt 2 vibrates, the piles of beans can fall and flatten autonomously, and automatically spread from the middle to the four sides, thereby entering the groove 3 and being pre-flattened. After that, when passing through the pre-leveling baffle 8, a single-layer outflow can be better formed. On the other hand, the vibration of the conveyor belt 2 by the short-amplitude vibrator 12 can also allow the beans in the groove 3 to be automatically arranged one by one and placed in the arc slot 11. Since the outer contour of the beans is an arc or spherical shape, the arc slots 11 are close to each other, and the gap between adjacent arc slots 11 is not enough to accommodate a complete bean, so the beans arranged linearly on the groove 3 gradually fall into the arc slots 11 under the short-amplitude vibration of the conveyor belt 2, and since the arc slots 11 are groove-shaped and have a certain diving depth, the beans entering the arc slots 11 are not easy to jump out of the arc slots 11, and can have enough force to push the subsequent arc stopper 41, and can only fall into the frying box under the tail of the conveyor belt 2. Among them, the short-amplitude vibrator 12 can be selected from the prior art vibrator that uses an eccentric disk to rotate for vertical vibration. Specifically, the dispersion bracket 13 may include a beating plate arranged below the pre-leveling baffle 8 and below the side of the pre-leveling baffle 8 away from the arrangement baffle 9, and the beating head of the short-amplitude vibrator 12 is vertically arranged below the center of the beating plate. Afterwards, the parameters of the short-amplitude vibrator 12 are adjusted to apply high-frequency and small-amplitude vibrations to the beating plate, so that the beating plate vibrates up and down, driving the designated area of ​​the conveyor belt 2 to vibrate, thereby completing the transformation of the piled beans on the conveyor belt 2 into a single layer of beans, and arranging the beans into the arc groove 11. In addition to this effect, the short-amplitude vibrator 12 drives the beans to vibrate, and can also separate the shell membranes on the beans that are easy to fall off and the debris that is at risk of cracking in advance and drop them into the groove 3 for collection, so as to prevent them from falling off during the frying process and contaminating the oil, thereby making the quality of the fried beans higher. In the traditional frying method, the above situation can easily occur when using a colander or a stirring blade in the frying box to break up the beans that have clumped together in the frying box, resulting in low quality of the finished beans.

[0044] Further, such as Figure 2As shown, in actual operation, in order to avoid the vibration of the conveyor belt 2 in the area of ​​the pre-leveling baffle 8 and affect the normal transportation of the beans on the conveyor belt 2 near the arranging baffle 9, the setting position of the pre-leveling baffle 8 can be pulled away from the setting position of the arranging baffle 9. That is, the spacing between the pre-leveling baffle 8 and the arranging baffle 9 is enlarged, and the influence of the vibration of the conveyor belt 2 in the area of ​​the pre-leveling baffle 8 is weakened by a large length span. In addition, a flat plate can be set at the horizontal approximate position of the beating plate. The setting position of the flat plate is closer to the conveyor belt 2 than the beating plate in the static position, and its setting position is behind the setting position of the pre-leveling baffle 8 (that is, toward the position of the arranging baffle 9). The purpose is that when the beating plate pushes the conveyor belt 2 to move up and down, the conveyor belt 2 in this area contacts the flat plate first, thereby reducing the amplitude of the conveyor belt 2 in this area and weakening the influence of the vibration. In addition, there are still many methods of reducing the amplitude of the conveyor belt 2 in the prior art, such as by setting an exhaust fan below the conveyor belt 2 at the position of the arranging baffle 9, and applying external force to the conveyor belt 2 by adsorption of the fan to avoid amplitude.

[0045] like Figure 2 As shown, further, a vertical baffle 14 is arranged on the side of the pre-leveling baffle 8 away from the arrangement baffle 9 and tilted toward the groove 3, or on the side of the pre-leveling baffle 8 away from the arrangement baffle 9. This is to prevent the beans on the conveyor belt 2 from jumping onto the pre-leveling baffle 8 when the short-amplitude vibrator 12 vibrates the conveyor belt 2. Therefore, the pre-leveling baffle 8 is tilted so that the beans entering its upper surface can slide down automatically, or the pre-leveling baffle 8 is arranged on the side away from the arrangement baffle 9 and a vertical baffle 14 is arranged to directly block the entry of the beans.

[0046] After the beans pass through the pre-leveling baffle 8, the state of the beans on the conveyor belt 2 is that part of them are in the groove 3 and part of them are in the temporary storage rail 4 (shallow groove). At this time, the beans in the groove 3 can enter the downstream of the conveyor belt 2 through the material gap on the arrangement baffle 9 and fall into the frying box, while the beans on the temporary storage rail 4 will gradually find the vacant arc slot 11 on the groove 3 in the way of upper and lower positions on the guide rail assembly 16, and automatically fall into the vacant position according to gravity, so as to realize the automatic sorting of the beans. Therefore, in actual use, the device is applied to the production line of intermittent feeding of the conveyor belt 2 for better effect. A material box is arranged upstream of the conveyor belt 2, and a large number of beans to be fried are loaded in the material box. The beans inside the material box are intermittently fed through the material port of the material box, and there is a time interval between adjacent feedings, so that a material pile with a spacing is formed on the conveyor belt 2, thereby reserving enough arc slots 11 to accommodate all the beans in a single pile of beans. That is, the vibration of the short-amplitude vibrator 12 may not be able to arrange all the beans in an orderly manner into the arc slots 11 on the groove 3, so that some of the arc slots 11 on the groove 3 are vacant, and the positions of the vacant arc slots 11 are uncertain. Therefore, the device is further provided with a guide rail assembly 16, and the guide rail assembly 16 is used to recover the beans on the temporary storage rail 4 and re-position them, so that the beans can be accurately distributed in all the arc slots 11 between adjacent material piles.

[0047] like Figure 3 , 4 , 5, 6, 7, and 8, specifically, the guide rail assembly 16 includes a split plate 15, one end of which is mounted on the arrangement baffle 9, and the other end extends toward the upstream direction of the conveyor belt 2. The split plate 15 is arranged in the middle of the temporary storage rail 4, and the two sides of the split plate 15 are symmetrically provided with a feeding belt 17, which is mounted on the bottom plate, and the two ends of the bottom plate are respectively connected to the inner fall table 18 and the table plate 19 to form an integral structure arranged above the conveyor belt 2. Alternatively, another connection method is that the rotating roller of the feeding belt 17 on the side close to the inner fall table 18 is installed on the inner fall table 18 through a connecting bracket, and the driving roller of the feeding belt 17 on the side close to the ramp surface 31 is installed on the ramp surface 31 through rotation, so that the inner fall table 18, the feeding belt 17 and the ramp surface 31 are still installed as a whole on the arrangement baffle 9, and are arranged above the conveyor belt 2. In the present device, all components for guiding the secondary feeding of beans on the temporary storage rail 4 are connected and mounted on the arrangement baffle 9, and then integrally mounted on the frame 1 by the bent baffle cover 5, so as to be separated from the conveyor belt 2, so that the device has better stability. The bottom end of the feeding belt 17 is arranged toward the temporary storage rail 4 and connected with a slope surface 31. The feeding belt 17 has two driving rollers, which are connected by a connecting belt to rotate synchronously.

[0048] The roller is provided with a feeding belt 17, and the end of the driving roller of the feeding belt 17 facing the slope surface 31 is fixedly connected with a friction roller 32, and the friction roller 32 contacts the temporary storage rail 4. The feeding belt 17 is provided with a limiting protrusion 30, so when the conveying belt 2 is in motion, it contacts the friction roller 32 to drive the friction roller 32 to rotate, and the driving roller is driven to rotate by the friction roller 32, thereby driving the feeding belt 17 to move to collect, lift and transport the beans on the temporary storage rail 4. The setting of the limiting protrusion 30 can prevent the beans from sliding down, and can better drive the beans into the inner inverted platform 18.

[0049] like Figure 3 As shown, the top of the feeding belt 17 extends toward the arrangement baffle 9 and is connected to the inner inverted platform 18. The top surface of the inner inverted platform 18 is inclined toward the groove 3 and is connected to the table 19 so that the beans transported to the top surface of the inner inverted platform 18 by the feeding belt 17 can directly slide onto the table 19. In actual production, if the length of the table 19 is relatively long, limiting edges (not shown in the figure) can be set on both sides of the table 19 to limit the beans from moving along the length direction of the table 19 to the ends thereof. The limiting edges are mainly set on the middle main body of the table 19, and the two ends of the table 19 are not set with limiting edges to facilitate the loading and falling of the beans. One end of the table 19 is fixedly mounted on the arrangement baffle 9 and is located above the material passing gap, and the other end extends toward the upstream direction of the conveyor belt 2, and this end can be tilted downward to facilitate the beans to slide into the unloading perforation 33.

[0050] A material cutting through hole facing the groove 33 is opened on the table 19, and the two sides of the material cutting through hole 33 are recessed outward to form an outward expansion groove 34 in the table 19. A carrier plate 35 is longitudinally slidably arranged in the outward expansion groove 34, and spring pieces 36 are supported and arranged at the two ends of the outward expansion groove 34 below the carrier plate 35. The spring pieces 36 are limited inside the carrier plate 35 by limiting grooves, and a top expansion piece 37 is arranged on one side of the spring piece 36.

[0051] like Figure 4 As shown, the interior of the carrier plate 35 is hollow, and two scissors 38 are fixedly arranged inside the carrier plate 35. The middle position of the scissors 38 is rotatably installed in the carrier plate 35 through a rotating shaft. The scissors 38 are similar to a scissors structure, which leads to synchronous opening and synchronous clamping of both ends. The synchronously clamped working end forms a stopper in the loading hole 39 for carrying beans. A loading hole 39 is opened in the middle position of the carrier plate 35, and the working ends of the two scissors 38 are arranged in the loading hole 39 for carrying the beans to be unloaded. The driving ends of the two scissors 38 are arranged toward the outward expansion groove 34, and a clearance hole 40 is opened at the bottom of the carrier plate 35 below the driving end of the scissors 38, and the clearance hole 40 is arranged opposite to the top expansion piece 37. In the process of the carrier plate 35 pressing down the spring sheet 36 and gradually sliding down, the top expansion piece 37 passes through the clearance hole 40 to push the driving end of the scissors 38 to drive the working end of the scissors 38 to open for unloading.

[0052] like Figure 8 As shown, arc stoppers 41 are provided on both sides of the loading holes 39 on the lower bottom surface of the carrier plate 35. The bottom surface of the arc stoppers 41 is at the same height as the bottom surface of the platform 19 when the carrier plate 35 has not slid down. The bottom surface of the platform 19 is provided close to the top of the beans in the arc groove 11.

[0053] The specific working process is: during the continuous movement of the conveyor belt 2, the conveyor belt 2 drives the feeding belt 2 to move continuously through the friction roller 32, and then transports the beans on the temporary storage rail 4 upward to the inner inverted table 18, and the inclined top surface of the inner inverted table 18 guides the beans to the table plate 19 until they are in the unloading perforation 33.

[0054] When the beans slide to the loading hole 39 located in the middle of the carrier plate 35 at the front end of the table 19, the carrier plate 35 is pressed down and slides downward in the outward expansion groove 34. Due to the support setting of the spring piece 36 (specifically, the spring piece 36 can be set to an arc-shaped convex shape, which spreads to both sides when pressed downward), the carrier plate 35 slides downward in the outward expansion groove 345 in a gradually falling posture. When the carrier plate 35 falls to the bottom of the outward expansion groove 34, the top expansion piece 37 in the outward expansion groove 34 completely squeezes the driving end of the scissor 38 inside the carrier plate 35, so that the driving end of the scissor 38 opens outward, driving its working end to open to both sides, so that the beans located above its working end fall.

[0055] like Figure 8 As shown, further, the device is provided with an arc stopper 41 on the lower bottom surface of the carrier plate 35, and the arc stopper 41 moves synchronously with the movement of the carrier plate 35. When the carrier plate 35 is pressed down, the arc stopper 41 can fall down and protrude from the bottom surface of the platform 19. At this time, if there are beans in the arc slot 11 below it, then as the conveyor belt 2 continues to convey, the beans will move forward and push the arc stopper 41, so that the carrier plate 35 rises and cannot fall to the bottom position, so that the top expansion member 37 cannot fully open the driving end of the scissor 38, so that the beans on the loading hole 39 cannot fall.

[0056] like Figure 3 As shown, when the arc slot 11 below the loading hole 39 is empty and not loaded with beans, the carrier plate 35 will squeeze the spring piece 36 and continue to descend until it reaches the bottom, so that the top expansion piece 37 squeezes the driving end of the scissor 38 to open and put the beans down, so that the beans can enter the empty arc slot 11 below.

[0057] In addition, since the beans before frying may be soft in texture, they are rotated by the vibration of the short-amplitude vibrator 12, causing a narrow position to fall into the groove 3, so they may be stuck in the arc groove 11 and difficult to fall by their own gravity. Therefore, the device is fixedly provided with a guide plate 21 at the downstream tail end of the conveyor belt 2, and a plurality of sawtooth blocks 22 are linearly arranged on the upper edge of the guide plate 21 along its width direction. The ends of the plurality of sawtooth blocks 22 are inserted into the groove 3 and are located below the arc groove 11, and there is a movable gap between the sawtooth blocks 22 and the side walls of the groove 3. During the operation of the conveyor belt 2, the beans stuck in the groove 3 are discharged through the sawtooth blocks 22. And the sawtooth blocks 22 with a movable gap between the groove 3 can avoid fitting with the side walls of the groove 3, thereby shoveling out the debris sunk to the bottom of the groove 3. Setting the head end of the sawtooth block 22 tangent to the bottom of the arc groove 11 can achieve a better effect. In addition, the guide plate 21 is provided to guide the beans to fall into the frying box, which can also prevent the beans from being broken due to the height difference when the beans fall directly into the frying box.

[0058] like Fig. 9 As shown, further, a friction tooth roller 23 is rotatably installed below the unloaded part of the lower layer of the conveyor belt 2, and the rotation direction of the friction tooth roller 23 is the same as the rotation direction of the conveyor belt 2. A plurality of velvet teeth 24 are arranged on the friction tooth roller 23, and the plurality of velvet teeth 24 are slidably engaged in the plurality of grooves 3 in a one-to-one correspondence, and the outer side walls of the velvet teeth 24 are arranged in contact with the inner side walls of the grooves 3. A blocking partition 25 is arranged below the friction tooth roller 23, and a plurality of blocking grooves 26 are opened at the top of the blocking partition 25. The plurality of velvet teeth 24 are synchronously and correspondingly slidably engaged in the plurality of blocking grooves 26, and the outer side walls of the velvet teeth 24 are arranged in contact with the inner side walls of the blocking grooves 26. The blocking partition 25 is arranged in the outer box 27, and the blocking partition 25 separates the outer box 27 into a slag storage chamber 28 and an oil storage chamber 29. Adhesive liquid oil is arranged in the oil storage chamber 29, and the liquid surface of the adhesive liquid oil is in contact with the velvet teeth 24.

[0059] When the groove 3 contains shell film and slag, the velvet teeth 24 meshing with the groove 3 can shovel them out during the operation of the groove 3. And the shoveled slag can be shoveled off the velvet teeth 24 again through the action of the blocking partition 25 and fall into the slag storage chamber 28.

[0060] In the prior art, the beans are transported by mesh chain belts or stirred and broken up in a frying box, which easily makes the beans stuck in the mesh and difficult to discharge, and the stirring process will produce debris, which increases the difficulty of cleaning and reduces the quality of the finished product. Therefore, the device performs pretreatment in advance, and the semi-detached debris and shell membrane are detached in advance, and collected by the groove 3. Finally, a friction tooth roller 23 is set under the conveyor belt 2, and the groove 3 is cleaned by the velvet teeth 24 of the friction tooth roller 23. At the same time, the friction tooth roller 23 is unloaded, and the velvet teeth 24 are oiled (the adhesive liquid oil can be food-grade silicone oil or edible oil directly), so that the groove 3 can pass through the oily adhesion shell membrane, thereby improving the adsorption and collection capacity of the groove 3.

The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
