Description

Technical Field

[0001] The present invention relates to the field of starch processing, and more particularly to an automatic feeding device during the processing of pea starch. Background Art

[0002] In the industrial production process of pea starch, the feeding link is a crucial one, and its efficiency and accuracy directly affect the stability of the entire production process and the product quality. Traditional feeding methods for pea starch mostly use manual operation or simple mechanical devices. Manual feeding is not only inefficient and difficult to meet the needs of large-scale production, but also during the operation process, due to different operating habits and proficiency levels of workers, it is easy to cause inaccurate feeding amounts, which in turn affects the subsequent processes of starch processing. For example, during the drying process of pea starch, uneven feeding amounts will cause uneven distribution of materials in the drying equipment. Some starches may be over-dried, affecting their quality, while some are not dried sufficiently and there is an agglomeration phenomenon.

[0003] Some existing automatic feeding devices, although they improve the feeding efficiency to a certain extent, still have many problems. Some devices cannot be flexibly adjusted according to the actual state of pea starch, such as the degree of moisture absorption and fluidity, resulting in difficulty in ensuring smooth and uniform feeding when dealing with pea starch in different states.

[0004] The existing automatic feeding devices have poor adaptability to pea starch in different states. Most devices can only operate in a fixed mode and cannot be intelligently adjusted according to the characteristics of pea starch such as the degree of moisture absorption and fluidity. When dealing with materials under different working conditions, problems such as blockage and unsmooth conveying often occur, which not only reduces the production efficiency but also increases the risk of equipment failure and affects the production stability of the enterprise. Therefore, it is necessary to design an automatic feeding device during the processing of pea starch. Summary of the Invention

When the fluidity of pea starch decreases, the material guiding belt is adjusted to a wavy shape to break up agglomerated particles, accelerate the drying speed, and avoid blockage. When the fluidity of pea starch is good, the material guiding belt is changed into a straight line to improve the feeding efficiency. This adaptive ability enables the device to be applicable to the treatment of pea starch under different working conditions, expands the application range of the device, improves the flexibility and adaptability of production, and meets different production requirements. Second: By setting a flow dividing cover at the upper end inside the feeding cylinder, the device can evenly disperse the airflow generated by the fan, enabling pea starch at all parts of the material guiding belt to fully contact the airflow, achieving a more uniform drying effect, avoiding the problem of insufficient drying or over-drying of some pea starch caused by uneven airflow distribution, effectively ensuring the quality of pea starch, reducing product quality fluctuations caused by drying problems, and improving the stability of production and the product qualification rate. Third: By setting a stretching mechanism to restrict the material guiding belt, during the process of adjusting the material guiding belt, the length of the material guiding belt can be adjusted through the reel to achieve automatic reset of the material guiding belt without manual intervention, improving the automation degree of the device, reducing the workload and error probability of manual operation. At the same time, the main clamping plate and the auxiliary clamping plate also ensure that after the material guiding belt switches between different shapes, starch leakage does not occur at the edge of the material guiding belt.

[0017] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0018] refer to Figures 1 to 10 , an automatic feeding device in a pea starch processing process, comprising a feeding cylinder 2 fixedly connected to the output end of a traveling vibrating screen 1, a feeding port 5 and a discharge port 6 formed on the feeding cylinder 2, and further comprising: A guide plate 3 is provided on one side of the feeding cylinder 2 near the feeding port 5 (see Figure 6), a curved plate 4 is provided at the lower end of the material guiding plate 3. A material guiding belt 7 is provided on the side of the curved plate 4 close to the material guiding plate 3. One side of the material guiding belt 7 is slidably connected to the curved plate 4, and the other side is slidably connected to the material guiding plate 3. A clamping plate 15 is fixedly connected to the end of the material guiding belt 7 away from the discharge port 6. A tensioning roller 24 is rotatably provided beside the discharge port 6, and a winding shaft 16 is rotatably provided below the tensioning roller 24. One end of the material guiding belt 7 close to the discharge port 6 bypasses the tensioning roller 24 and is wound and connected to the winding shaft 16. An electric slide plate 8 for blocking the discharge port 6 is provided at the discharge port 6. A blower 9 is provided on the side of the electric slide plate 8 close to the feeding port 5. When the blower 9 is started, it blows air into the feeding cylinder 2. An extension mechanism 11 is further provided on the feeding cylinder 2. The extension mechanism 11 includes a lead screw motor 12 provided at one end of the feeding cylinder 2 away from the discharge port 6 and a plurality of deflection frames 35 fixedly provided below the material guiding belt 7. A deflection block 36 in contact with the material guiding belt 7 is rotatably provided at the upper end of the deflection frame 35. When the lead screw motor 12 is started, it drives the material guiding belt 7 to move through the clamping plate 15. A set of anti-displacement mechanisms 37 are respectively provided on both sides of the feeding cylinder 2. The anti-displacement mechanism 37 includes two main clamping plates 40 and two sub-clamping plates 46 that move alternately, and the main clamping plates 40 and the sub-clamping plates 46 respectively limit the material guiding belt 7 before and after deformation.

[0019] When the device is operating, pea starch enters the feeding cylinder 2 and falls from the feeding port 5 onto the material guiding plate 3. Subsequently, the pea starch will fall onto the material guiding belt 7 along the material guiding plate 3. Subsequently, the traveling vibrating screen 1 will be started during this process and drive the feeding cylinder 2 to vibrate. During this process, the blower 9 will be started and the pea starch will be dried by the air flow to prevent the pea starch from agglomerating. Finally, the pea starch leaves the feeding cylinder 2 from the discharge port 6 after the electric slide plate 8 rises.

[0020] During the above process, the extension mechanism 11 can change the shape of the material guiding belt 7 by changing the inclination angles of a plurality of deflection blocks 36. The material guiding belt 7 needs to be selected between a wavy shape and a straight shape before the pea starch enters the feeding cylinder 2 according to the state of the pea starch: When the fluidity of pea starch decreases due to moisture absorption or other reasons, the material guiding belt 7 can be adjusted to a wavy shape. The wavy material guiding belt 7 causes the material to continuously experience the processes of rising and falling during movement, which generates forces in different directions. Under the action of these forces, the agglomerated pea starch particles are more easily dispersed, making the pea starch more dispersed. At the same time, the drying gas blown by the fan 9 can more fully contact the pea starch under the action of the wavy material guiding belt 7, accelerating the drying speed and further improving the fluidity of the pea starch. In addition, the wavy structure can divide the pea starch into multiple small parts, and each wave crest and wave trough can accommodate a certain amount of pea starch. In this way, even if the fluidity of the pea starch is poor, it is not easy to accumulate in large quantities at a certain place, but is relatively evenly distributed on the material guiding belt 7. Moreover, when the pea starch flows from the wave crest to the wave trough, it will be affected by gravity and inertial forces, which helps to push the pea starch to continue moving forward, thus maintaining the continuous flow of the pea starch and avoiding the blockage problem caused by the accumulation of pea starch.

[0021] When the pea starch is in a dry state and has good fluidity, the material guiding belt 7 can be changed to a straight line shape. The straight material guiding belt 7 can provide a more direct and smooth flow path for the pea starch, reduce the residence time of the pea starch on the material guiding belt 7, and improve the feeding efficiency.

[0022] When the material guiding belt 7 changes from a straight line shape to a wavy shape, since one end of the material guiding belt 7 close to the reel 16 is wound around the outside of the reel 16, when the material guiding belt 7 undergoes a curved deformation, the material guiding belt 7 releases the part wound around the reel 16 by driving the reel 16 to rotate, thereby changing its own length to adapt to this deformation. And the main clamping plate 40 and the auxiliary clamping plate 46 on the anti-displacement mechanism 37 will limit the material guiding belt 7 before and after the deformation, preventing the edge of the material guiding belt 7 from deforming when loaded with pea starch, resulting in the pea starch leaking downward through the material guiding belt 7.

[0023] In order to correctly divide the airflow generated by the fan 9, the following features are specifically set: A flow dividing cover 10 is fixedly connected to the upper end inside the feeding cylinder 2 (refer to Figure 6 ). The upper end of the flow dividing cover 10 is communicated with the output end of the fan 9, and a number of air holes are formed in an equally spaced array at the lower end. After the fan 9 is started, the generated airflow will enter the inside of the flow dividing cover 10 through the upper end of the flow dividing cover 10. Due to the air holes formed in an equally spaced array at the lower end of the flow dividing cover 10, the airflow will be evenly dispersed and blown onto the pea starch inside the feeding cylinder 2 at a stable and uniform flow rate. This can ensure that the pea starch at all parts on the material guiding belt 7 can fully contact the airflow, achieving a more uniform drying effect, avoiding the problem of insufficient drying or over-drying of some pea starch due to uneven airflow distribution, and at the same time also helping to improve the effect of the airflow in dispersing the agglomerated pea starch, making the state of the pea starch on the material guiding belt 7 more ideal.

[0024] To limit the movement of the clamping plate 15 and prevent the guide belt 7 from running amok during movement, the following features are specifically provided: The stretching mechanism 11 further includes a pull rod 13 and two limiting rods 14. One end of the pull rod 13 is fixedly connected to the clamping plate 15 (refer to Figure 8 ), and the other end is fixedly connected to the output end of the lead screw motor 12. The two limiting rods 14 are respectively arranged on both sides of the pull rod 13. One end of the limiting rod 14 is fixedly connected to the clamping plate 15, and the other end is key-connected to the feeding cylinder 2. After the lead screw motor 12 is started, the output end of the lead screw motor 12 drives the clamping plate 15 to move through the pull rod 13, so as to realize the stretching or contraction operation of the guide belt 7. The setting of the two limiting rods 14 can limit the direction of the clamping plate 15 during movement, ensure that the clamping plate 15 can only move along the direction parallel to the limiting rod 14, prevent the clamping plate 15 from shifting or shaking during movement, and further ensure that the guide belt 7 will not run amok during movement, so that the guide belt 7 can change its shape according to a predetermined trajectory and manner. Whether it changes from a straight shape to a wavy shape or from a wavy shape back to a straight shape, it can be carried out stably and reliably.

[0025] To endow the reel 16 with the ability to reset, the following features are specifically provided: The stretching mechanism 11 further includes two reset gears 17, two connecting gears 18, two reset racks 19, two reset baffles 20, two reset springs 21, two reset shafts 22 and two positioning baffles 23. The two reset gears 17 are respectively fixedly connected to both ends of the reel 16 (refer to Figure 5), two connecting gears 18 are respectively arranged beside the two reset gears 17. The connecting gear 18 is rotationally connected to the side wall of the feeding cylinder 2 and meshes with the reset gear 17. Two reset racks 19 are respectively arranged beside the two connecting gears 18. The reset rack 19 meshes with the connecting gear 18. The upper ends of the two reset racks 19 are respectively fixedly connected with reset baffles 20. The lower ends of the two reset shafts 22 are respectively fixedly connected with the two reset baffles 20. Above the two reset racks 19, positioning baffles 23 fixedly connected to the side wall of the feeding cylinder 2 are respectively arranged. The reset shaft 22 is key-connected to the positioning baffle 23. Two reset springs 21 are respectively sleeved outside the two reset shafts 22. The upper end of the reset spring 21 is fixedly connected to the positioning baffle 23, and the lower end is fixedly connected to the reset baffle 20. When the guide belt 7 changes from a straight shape to a wavy shape, the guide belt 7 drives the reel 16 to rotate, and the reset gears 17 at both ends of the reel 16 rotate accordingly. Through meshing with the connecting gear 18, the reset rack 19 is driven to move upward, and the reset spring 21 is compressed. When it is necessary to change the guide belt 7 from a wavy shape back to a straight shape, the elastic force of the reset spring 21 pushes the reset baffle 20 and the reset rack 19 to move downward. Through the transmission between the connecting gear 18 and the reset gear 17, the reel 16 rotates in the reverse direction, and the guide belt 7 is rewound on the reel 16 again, realizing the reset of the guide belt 7, ensuring that the guide belt 7 can flexibly switch between different shapes and has good reset ability, and providing guarantee for the stable operation of the device.

[0026] In order to limit the guide belt 7 and prevent the guide belt 7 from moving around, the following features are specifically set: The stretching mechanism 11 further includes a plurality of positioning arc blocks 25 and a plurality of positioning rollers 26. The plurality of positioning arc blocks 25 are arranged at equal intervals along the inner side of the feeding cylinder 2 (refer to Figure 7 and Figure 8 ), both ends of the positioning arc block 25 are fixedly connected to the side wall of the feeding cylinder 2, the lower end of the positioning arc block 25 is in sliding contact with the upper end of the guide belt 7, and a plurality of positioning rollers 26 are respectively arranged beside the plurality of positioning arc blocks 25 and are in sliding contact with the lower end of the guide belt 7. Both ends of the positioning roller 26 are rotationally connected to the side wall of the feeding cylinder 2. During the movement and shape change of the guide belt 7, the positioning arc block 25 can limit the guide belt 7 from above, preventing the guide belt 7 from moving upward and ensuring that the guide belt 7 is always at an appropriate height position. The positioning roller 26 contacts the guide belt 7 from below. While restricting the downward movement of the guide belt 7, the friction during the movement of the guide belt 7 is reduced by rolling, enabling the guide belt 7 to move and change shape more smoothly in the feeding cylinder 2. Moreover, the arrangement of the positioning arc block 25 and the positioning roller 26 can also support the guide belt 7 to a certain extent, ensuring the stability of the guide belt 7 when carrying pea starch.

[0027] In order to drive a plurality of deflection blocks 36 to deflect, the following features are specifically set: The stretching mechanism 11 also includes a main motor 27, a first bevel gear 28, a second bevel gear 29, a plurality of main pulleys 30, a plurality of main roller shafts 31, a plurality of first pulleys 32, a plurality of second pulleys 33 and a plurality of auxiliary roller shafts 34. The main motor 27 is arranged beside the curved plate 4. The first bevel gear 28 is rotatably arranged beside the main motor 27 through the bevel gear frame. The first bevel gear 28 is coaxially fixedly connected to the output end of the main motor 27. The second bevel gear 29 is rotatably connected to the bevel gear frame and meshes with the first bevel gear 28. The plurality of main roller shafts 31 are rotatably connected to the lower part of the plurality of deflection frames 35 respectively. The plurality of main pulleys 30 are respectively connected to the middle of several main roller shafts 31, two adjacent main pulleys 30 are connected by belt transmission, the main pulley 30 near the main motor 27 is coaxially connected to the second bevel gear 29, and first pulleys 32 connected to the main roller shaft 31 are respectively arranged on both sides of the main pulley 30, several secondary roller shafts 34 are respectively rotatably connected to the upper part of several deflection frames 35 and are connected to the corresponding deflection blocks 36, several second pulleys 33 are respectively arranged above several first pulleys 32 and are connected to the corresponding secondary roller shafts 34, and the second pulleys 33 are connected to the first pulleys 32 by belt transmission. When the shape of the guide belt 7 needs to be changed, the main motor 27 is started, and the output end of the main motor 27 drives the first bevel gear 28 to rotate. The first bevel gear 28 transmits power to the main pulley 30 near the main motor 27 by meshing with the second bevel gear 29, and the main pulley 30 drives the adjacent main pulleys 30 to rotate in sequence through the belt, thereby rotating each main roller shaft 31. When the main roller 31 rotates, the second pulley 33 is driven to rotate through the first pulley 32 and the belt, so that the auxiliary roller 34 is rotated. The rotation of the auxiliary roller 34 drives the deflection block 36 connected to the auxiliary roller 34 to deflect. Through the coordinated deflection of multiple deflection blocks 36, the shape of the guide belt 7 is changed, so that it can be flexibly switched between wavy and straight shapes to adapt to pea starch in different states.

[0028] In order to drive the main card board 40 to move, the following features are also specifically provided: The anti-slip mechanism 37 also includes a cylinder 38 and a plurality of guide rollers 39. The cylinder 38 is fixedly connected to the feeding barrel 2 through a bracket. The plurality of guide rollers 39 are arranged in an array at equal intervals along the long side direction of the feeding barrel 2. One end of the guide roller 39 is fixedly connected to the feeding barrel 2, and the other end is slidably connected to the main card plate 40. The output end of the cylinder 38 is fixedly connected to the main card plate 40. When the guide belt 7 becomes a straight line, in order to prevent the edge of the guide belt 7 from slipping, the cylinder 38 is started, and the output end of the cylinder 38 pushes the main card plate 40 to move along the direction of the guide roller 39. The setting of the guide roller 39 can provide a stable guide for the movement of the main card plate 40, ensuring that the main card plate 40 can accurately move to the predetermined position (refer to Figure 2), the edges of the material guiding belt 7 before and after deformation are limited to restrict the movement of the material guiding belt 7 in the horizontal direction, thereby effectively preventing the pea starch from escaping from the edges of the material guiding belt 7 and ensuring the smooth progress of the feeding process and the stability of the material.

[0029] In order to drive the auxiliary clamping plate 46 to move, the following features are specifically set: The anti-escape mechanism 37 further includes a clamping motor 41, a driving pulley 42, two driven pulleys 43, two driven gears 44 and four driven racks 45. The clamping motor 41 is fixedly connected to the side wall of the feeding cylinder 2 through a motor bracket. The driving pulley 42 is coaxially fixedly connected to the output end of the clamping motor 41. The driving pulley 42 is rotatably connected to the side wall of the feeding cylinder 2. The two driven pulleys 43 are respectively arranged on both sides of the driving pulley 42 and are rotatably connected to the side wall of the feeding cylinder 2. The two driven gears 44 are respectively coaxially fixedly connected to the two driven pulleys 43. Driven racks 45 are respectively arranged on both sides of each driven gear 44. The driven racks 45 are engaged with the driven gears 44. The driven racks 45 are slidably connected to the side wall of the feeding cylinder 2 and one end is fixedly connected to the auxiliary clamping plate 46. When the material guiding belt 7 becomes wavy, the clamping motor 41 is started and drives the driving pulley 42 to rotate (refer to Figure 2 ), the driving pulley 42 drives the two driven pulleys 43 to rotate through a belt. The driven pulleys 43 drive the driven gears 44 coaxially fixedly connected thereto to rotate. The driven gears 44 drive the driven racks 45 to slide along the side wall of the feeding cylinder 2 through the engagement with the driven racks 45. The movement of the driven racks 45 drives the auxiliary clamping plate 46 to move until one end of the auxiliary clamping plate 46 close to the clamping motor 41 abuts against the outside of the wavy material guiding belt 7, further enhancing the restraining ability of the material guiding belt 7 and ensuring that the material guiding belt 7 can stably carry the pea starch under various working conditions, preventing the pea starch from leaking downward from the edges of the material guiding belt 7 due to the fact that the edges of the material guiding belt 7 cannot be in close contact with the inner wall of the feeding cylinder 2 during the process of loading the pea starch.

[0030] The working principle of this device is that when the pea starch enters the feeding cylinder 2, it will fall from the feeding port 5 onto the material guiding plate 3 and then slide along the material guiding plate 3 onto the material guiding belt 7. During this process, the traveling vibrating screen 1 is started and drives the feeding cylinder 2 to vibrate, which helps the pea starch to be evenly distributed on the material guiding belt 7. At the same time, the blower 9 is started, and the generated air flow is evenly dispersed through the shunt cover 10 and blown onto the pea starch to dry it and prevent the pea starch from agglomerating.

[0031] When it is necessary to adjust the shape of the material guiding belt 7 according to the state of pea starch, if the fluidity of pea starch decreases due to moisture absorption or other reasons, the main motor 27 starts. Through the transmission of components such as the first bevel gear 28, the second bevel gear 29, the main pulley 30, the main roller shaft 31, the first pulley 32, the second pulley 33, and the auxiliary roller shaft 34, a number of deflection blocks 36 are driven to deflect, causing the material guiding belt 7 to change from a straight shape to a wavy shape. At this time, one end of the material guiding belt 7 close to the reel 16 is wound around the outside of the reel 16. When the material guiding belt 7 undergoes a curved deformation, it drives the reel 16 to rotate and release the wound part to adapt to its own length change. At the same time, the air cylinder 38 and the engaging motor 41 in the anti-displacement mechanism 37 are started respectively. The air cylinder 38 pushes the main clamping plate 40, and the engaging motor 41 drives the auxiliary clamping plate 46 to move. The main clamping plate 40 and the auxiliary clamping plate 46 limit the material guiding belt 7 before and after deformation to prevent the leakage of pea starch. The wavy material guiding belt 7 causes the material to continuously rise and fall during the movement process, generating forces in different directions, breaking up the agglomerated pea starch particles, and enabling the drying gas blown by the fan 9 to more fully contact the pea starch, accelerating the drying speed, improving the fluidity, and also avoiding material accumulation and blockage.

[0032] When the pea starch is in a dry state and has good fluidity, the main motor 27 rotates in the reverse direction. Through the transmission components, the deflection blocks 36 deflect in the reverse direction, changing the material guiding belt 7 into a straight shape, providing a more direct and smooth flow path for the pea starch, reducing the residence time of the pea starch on the material guiding belt 7, and improving the feeding efficiency. During the process of changing the shape of the material guiding belt 7, the pull rod 13 and the limit rod 14 in the stretching mechanism 11 ensure the stability of the movement of the clamping plate 15. The positioning arc block 25 and the positioning roller 26 limit and support the material guiding belt 7. The reset mechanism composed of components such as the reset gear 17, the connecting gear 18, the reset rack 19, and the reset spring 21 can make the material guiding belt 7 return to its original position smoothly after the shape change. Finally, when the pea starch is dried and its fluidity reaches an appropriate state, the electric skateboard 8 rises, and the pea starch leaves the feeding cylinder 2 from the discharge port 6, completing the entire automatic feeding process.

[0033] The above embodiments only represent one or several implementation manners of the present invention, and the description is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the appended claims.
