[0032] The present invention will be further described in detail below in conjunction with specific implementations and with reference to the accompanying drawings. It should be emphasized that the following description is merely exemplary and is not intended to limit the scope of the present invention and its application.
[0033] Non-limiting and non-exclusive embodiments will be described with reference to the following figures, wherein like reference numerals refer to like parts unless otherwise specifically stated.
[0034] like Figure 1 and Figure 2 A rice noodle conveyor frame shown includes a frame 10 and a feeding device installed on the frame 10, wherein the feeding device includes a first conveyor, a second conveyor, and a third conveyor, wherein the first conveyor, the second conveyor, and the third conveyor are arranged in sequence, and the material is transferred from the first conveyor to the second conveyor and then to the third conveyor.
[0035] The first conveyor includes two sets of first chain transmission groups arranged in parallel, the first chain transmission groups include a first driving sprocket 13, a first driven sprocket 11 and a first chain 12, the first chain 12 links the first driving sprocket 13 and the first driven sprocket 11, and the first driving sprockets 13 of the two first chain transmission groups are linked through the first rotating shaft 14. The first driving sprocket 13 is driven by a motor to rotate, and the first driving sprockets 13 of the two first chain transmission groups are rotated synchronously through the first rotating shaft 14, driving the respective first chains 12 to rotate, and then the powder hanging rod placed on the first chain 12 can be transported to the target position. During operation, the powder hanging rod 20 is placed horizontally, and its two ends are placed on the upper side of the first chains 12 of the two first chain transmission groups. When the first driving sprocket 13 rotates, the first chain 12 drags the powder hanging rod 20 to move. Preferably, the first chain transmission group includes two first driven sprockets 11, and the first driving sprocket 13 is located between the two first driven sprockets 11. Installing the first driving sprocket 13 in the middle can prevent workers from accidentally touching the first rotating shaft 14 and the first driving sprocket 13. The tension of the chain can be better adjusted through the combination of three sprockets. The positions of the two ends of the powder hanging rod 20 are positioned using the shallow pits formed in each section of the first chain 12 to prevent the powder hanging rod 20 from crossing positions during the movement of the first conveyor, which affects the efficiency of the subsequent transfer to the second conveyor.
[0036] Continue to refer to Figure 1 The second conveyor is installed at the feeding end of the first conveyor, and its feeding end is tilted upward and intersects with the third conveyor. The second conveyor includes two sets of second chain transmission groups arranged in parallel, and the two sets of second chain transmission groups intersect with the feeding ends of the two sets of first chain transmission groups respectively. The second chain transmission group includes a second active sprocket 39, a second driven sprocket, a paddle 36 and a second chain 32. The second chain 32 tensions and links the second active sprocket 39 and the second driven sprocket. Several paddles 36 are fixed at intervals on the side of the second chain 32 to support the powder hanging rod 20 on the second conveyor and limit the powder hanging rod 20 from sliding backward. The powder hanging rod 20 on the first conveyor is picked up by the paddle 36 and placed on the second chain 32 of the second conveyor. During the process of transporting the powder hanging rod 20 to the third conveyor, the paddle 36 limits the powder hanging rod 20 from sliding backward due to its own weight.
[0037] In some preferred embodiments, Figure 3, a push rod mechanism is also provided at the intersection of the first conveyor and the second conveyor. By setting the push rod mechanism, the powder hanging rod 20 is pushed to the position where the paddle 36 can lift it, ensuring that each paddle 36 can lift a powder hanging rod 20, thereby improving the conveying continuity and conveying efficiency. The push rod mechanism includes a first cylinder 22, a positioning pressure rod 25, and a movable block 24. The movable block 24 is installed at the end of the telescopic rod of the first cylinder 22. The positioning pressure rod 25 is tilted, and its upper end is fixed on the movable block 24, and the lower end extends to the intersection of the first conveyor and the second conveyor. When the first cylinder 22 is extended, the positioning pressure rod 25 is driven to move downward, so that the lower end of the positioning pressure rod 25 contacts the upper side of the powder hanging rod closest to the second conveyor; the first cylinder 22 continues to extend, and then the powder hanging rod 20 is pressed toward the second conveyor through the positioning pressure rod 25, so that the powder hanging rod 20 is close to or abuts against the second conveyor. Preferably, the first cylinder 22 is a double telescopic rod cylinder.
[0038] The push rod mechanism also includes a first sensor 23, which is installed at the intersection of the first conveyor and the second conveyor, and is used to identify the position of the powder hanging rod closest to the second conveyor. When the powder hanging rod 20 moves to the sensing position of the first sensor 23 with the first conveyor, a signal is transmitted, and the first conveyor stops running. At the same time, the telescopic rod of the first cylinder 22 is controlled to extend to support the side of the powder hanging rod 20 closest to the second conveyor to prevent the powder hanging rod 20 from flowing back, so that the powder hanging rod closest to the second conveyor is within a predetermined range, waiting for the paddle 36 to transfer the powder hanging rod 20. In this embodiment, when the first conveyor stops, if the distance between the powder hanging rod closest to the second conveyor and the second conveyor is far, it is not conducive to the paddle 36 to pick up the powder hanging rod. Therefore, the powder hanging rod 20 is pushed toward the second conveyor by the positioning pressure rod 25, and the distance between the powder hanging rod and the second conveyor is reduced, which is conducive to the paddle 36 to pick up the powder hanging rod.
[0039] In the above embodiment, a mounting plate 21 is further included, the first cylinder 22 is fixed on the mounting plate 21, and the lower part of the mounting plate 21 is fixed on the frame 10 by bolts. The first sensor 23 is also fixed on the mounting plate 21.
[0040] In a preferred embodiment, the first driven sprocket 11 at the feeding end of the first conveyor is coaxial with one of the second driven sprockets of the second conveyor. The first driven sprocket 11 and / or the second driven sprocket are bearing hole sprockets, and the sprockets of this structure will not rotate with the connecting shaft, so that although the first driven sprocket 11 and the second driven sprocket are coaxial, they rotate independently of each other.
[0041] In some embodiments, the second chain transmission group includes three second driven sprockets, wherein the second driven sprocket I31 is coaxial with the first driven sprocket 11 at the feeding end of the first conveyor, the second driven sprocket II35 is located at the upper right of the second driven sprocket I31, and at the upper left of the second driven sprocket III37; the second driving sprocket 39 is located at the lower right of the second driven sprocket I31, and at the lower left of the second driven sprocket II35. The highest point of the second driven sprocket III37 is located 10-20 mm above the third conveyor to reduce the amount of powder falling.
[0042] In a preferred embodiment, the first adjustment axis 33 and the second adjustment axis 34 are further included. The first adjustment axis 33 and the second adjustment axis 34 are used to adjust the state of the rice noodles on the powder hanging rod 20, and gradually adjust the rice noodles vertically hanging on the powder hanging rod 20 to a state with an inclination angle less than 8°, so as to prevent the rice noodles from falling during the transition of the powder hanging rod 20 from the second conveyor to the third conveyor. When the powder hanging rod 20 is transported, the rice noodles move in a vertical state during the transfer process between the first conveyor and the second conveyor, but the rice noodles need to be spread flat on the third conveyor. Therefore, the inclination angle of the rice noodles needs to be adjusted so that the rice noodles form a smaller angle with the third conveyor when they contact it, such as less than 8°. Specifically, the first positioning axis 33 and the second positioning axis 34 are both located in the area surrounded by the second chain 32, and both ends of the first positioning axis 33 are fixed on both sides of the frame 10, and the first positioning axis 33 is located at the lower left of the second positioning axis 34, and the horizontal height of the second positioning axis 34 is 10-30 mm lower than the conveying surface of the third conveyor, so that the rice noodles are at a small inclination angle before contacting the third conveyor. The distance between the first positioning axis 33 and the second positioning axis 34 is less than the length of the rice noodles.
[0043] In the above, during the operation of the second conveyor, the rice noodles on the noodle hanging rod 20 are adjusted by the first positioning shaft 33 and the second positioning shaft 34. When the rice noodles are completely separated from the second positioning shaft 34, the middle part of the rice noodles drops to the conveying surface of the third conveyor. At this time, the noodle hanging rod is still on the second chain 32, keeping the conveying speeds of the second conveyor and the third conveyor basically the same.
[0044] Combination Figure 4, the third conveyor is a belt conveyor, which includes a body 44 and a conveying assembly installed on the body 44. After the powder hanging rod 20 moves to the third conveyor, the powder hanging rod 20 needs to be pulled out to facilitate the packaging of rice noodles. If the powder hanging rod 20 is directly pulled out, the rice noodles will be misplaced or stacked together during the process of pulling out the powder hanging rod. The rice noodles need to be re-arranged during packaging, which not only increases the labor of the workers, but also affects the work efficiency, and the risk of rice noodles breaking is increased during the process of arranging the rice noodles, which is not conducive to product quality control. The reason is that the rice noodles are soft when they are hung on the powder hanging rod. After drying and shaping, the rice noodles and the powder hanging rod 20 are closely connected. If the powder hanging rod is forcibly pulled out, the order of the rice noodles will inevitably be disturbed. For this reason, a loose rod assembly is designed, which includes a lever mechanism and a positioning block 41. The two positioning blocks 41 are respectively fixed on both sides of the body 44 of the third conveyor and have a certain distance from the second conveyor. The lever mechanism includes a lever 62 and a driving device that drives the lever 62 to move so as to push the powder-hanging rod 20 toward the positioning block 41. The lever mechanism has various forms, and is used to push the two ends of the powder-hanging rod transferred by the second conveyor, so that the powder-hanging rod hits the positioning block 41, and the contact between the powder-hanging rod 20 and the rice noodles is loosened by the vibration impact generated by the collision between the powder-hanging rod 20 and the positioning block 41, so that the rice noodles adhered to the powder-hanging rod are separated. In addition, when the powder-hanging rod 20 hits the positioning block 41, the powder-hanging rod tends to rebound backwards due to the reaction force, and the rice noodles continue to move forward under the action of inertia, so that the powder-hanging rod and the rice noodles are separated by relative movement, which is conducive to pulling out the powder-hanging rod. There are many ways to push the powder hanging rod to move. It is preferred to use the method of hitting the two ends of the powder hanging rod 20 to push the powder hanging rod toward the positioning block 41. In this way, when the lever 62 hits the powder hanging rod, a first instantaneous vibration is generated, and when the powder hanging rod hits the positioning block 41, a second instantaneous vibration is generated. Through two instantaneous vibrations, the success rate of separation of the powder hanging rod and rice noodles is improved. In order to ensure that the distance between the two ends of the powder hanging rod and the positioning block 41 is close after hitting the positioning block 41, the powder hanging rod 20 is pressed toward the positioning block 41 by the lever 62. In this way, after the powder hanging rod hits the positioning block 41, the lever 62 supports the powder hanging rod, and the rebound of the powder hanging rod is limited and within a predetermined range, so that the powder hanging rod abuts against the side of the positioning block 41.
[0045] According to the spatial structure of the frame of the present application, the lever mechanism is installed below the third conveyor. In order to facilitate control and keep the working environment clean, the second cylinder 61 is used as a driving device, and the lever 62 is driven to approach or move away from the positioning block 41 through the telescopic activity of the telescopic rod of the second cylinder 61. For example, the middle part of the lever 62 is rotatably connected to the frame 10 through a pin, wherein the lower end of the lever 62 is hinged to the end of the telescopic rod of the second cylinder 61, and the upper end extends to the interval between the third conveyor and the frame 10. The lever 62 is driven to rotate around the pin by the telescopic activity of the second cylinder 61, so that the upper end of the lever 62 can push the powder hanging rod toward the positioning block 41. For another example, the lever 62 adopts a connecting rod mechanism, and the telescopic movement of the second cylinder 61 drives the connecting rod mechanism to reciprocate, thereby driving the lever 62 to approach or move away from the positioning block 41.
[0046] In some embodiments, focus on Figure 5 and Figure 6 , further comprising a crank rod 64, both ends of which are rotatably mounted on both sides of the frame 10 through bearings 63, and the shifting rod 62 is fixed respectively, the telescopic rod of the second cylinder 61 is hinged at the curved part of the crank rod 64, and the telescopic movement of the second cylinder 61 pushes the crank rod 64 to reciprocate, thereby driving the shifting rod 62 to approach or move away from the positioning block 41. For example, it further comprises a fifth connecting rod and a sixth connecting rod, one end of the fifth connecting rod 65 is hinged to the curved part of the crank rod 64, and the other end is hinged to the sixth connecting rod 66; the other end of the sixth connecting rod 66 is hinged to the telescopic rod of the second cylinder 61; the bottom of the second cylinder 61 is hinged to the frame 10.
[0047] In a preferred embodiment, a pad 42 is further included, which is fixed on both sides of the body 44 of the third conveyor and extends from the positioning block 41 to the intersection of the second conveyor and the third conveyor. When the powder-coating rod 20 detaches from the second conveyor and falls onto the pad 42, the pad increases the distance between the powder-coating rod 20 and the conveyor belt of the third conveyor, which is conducive to the separation of the powder-coating rod from the rice noodles after the impact.
[0048] The conveyor belt of the third conveyor is a mesh conveyor belt, which has a certain deformation capacity. Figure 7-8A truss 50 is also installed above the third conveyor, and the lower end of the truss 50 is fixed on the frame 10. It also includes a rod extraction assembly, which is used to pull out the powder hanging rod 20, and includes a powder pressing device, a powder fixing device, a rod extraction device, a rod shifting device and a second sensor 38. When the powder hanging rod is pulled out, the second sensor 38 obtains a signal I of the powder hanging rod 20 entering the third conveyor from the second conveyor; the third conveyor is stopped according to the signal I, and the second cylinder 61 is controlled to drive the lever 62 to swing, and the lever 62 hits the powder hanging rod 20 against the positioning block 41 and then returns to its original position; the powder pressing device presses down the rice flour on the powder hanging rod 20 to be pulled out, and the lever shifting device moves the powder hanging rod to the second conveyor side by a certain distance to the position, and then resets the powder pressing device; then drives the powder fixing device to limit the lateral movement of the rice flour, and resets the lever shifting device; then, the rod extraction device clamps one end of the powder hanging rod 20, pulls out the powder hanging rod 20 and resets it; the powder fixing device is reset, and the third conveyor restarts to carry out the transportation operation. Specifically, the powder pressing device and the powder fixing device are arranged horizontally, and perpendicular to the extending direction of the rice flour on the third conveyor.
[0049] Among them, combined Fig. 9 The powder pressing device is installed at the rear end of the truss 50, and includes a powder pressing cylinder 74, a first mounting plate 73, and a pressing roller assembly. The first mounting plate 73 is fixed on the truss 50, and the powder pressing cylinder 74 is installed in the middle thereof, and the end of the telescopic rod of the powder pressing cylinder 74 is connected to the pressing roller assembly. The pressing roller assembly is driven to approach or move away from the third conveyor by the telescopic movement of the powder pressing cylinder 74. Preferably, it also includes a first guide assembly 72, and two groups of the first guide assemblies 72 are installed on the first mounting plate 73, and the lower end is connected to the pressing roller assembly, which is used to guide the pressing roller assembly and improve the activity reliability of the pressing roller assembly. The pressing roller assembly includes a pressing roller 71 and a frame 75 for installing the pressing roller 71. The powder pressing cylinder 74 and the first guide assembly 72 are both connected to the frame 75, and the pressing roller 71 is a roller structure, and its lower end protrudes from the lower side of the frame 75. When the powder pressing cylinder 74 is extended, the pressing roller 71 moves downward and is pressed on the rice flour to prevent the rice flour from moving when the moving rod device moves the powder hanging rod 20.
[0050] Combination Fig.10, two rod shifting devices are installed at the rear side of the truss 50, and are used to move the powder hanging rod 20 to the second conveyor frame side. The rod shifting devices include a first guide rail 91, a first slider 92, a rod shifting driving device, a rod shifting cylinder 95, and a pressing plate 98. The first guide rail 91 is installed at the rear side of the truss 50, and is equipped with the first slider 92. The first slider 92 is driven to reciprocate on the first guide rail 91 by the rod shifting driving device. The rod shifting cylinder 95 is installed on the first slider 92, and the pressing plate 98 is installed at the end of its telescopic rod. When working, the rod shifting cylinder 95 extends to press the pressing plate 98 on the powder hanging rod 20; then the rod shifting driving device pushes the first slider 92 to move to the second conveyor side, and then the pressing plate 98 rolls the powder hanging rod 20 to a predetermined position. The pressing plate 98 and the pad 42 are used to sandwich the powder hanging rod 20 in the middle. When the rod shifting cylinder 95 moves with the first slider 92, the powder hanging rod 20 can be rolled to the second conveyor side. The powder-coating rod 20 rolls and moves, which can reduce the friction with the rice powder.
[0051] Preferably, the rod shifting driving device is a connecting rod driving mechanism, which includes a rod shifting motor, a driving shaft 96, a third connecting rod 97, and a fourth connecting rod 94. Both ends of the driving shaft 96 are mounted on the frame through bearings, and are located between the third conveyor and the truss 50, and are linked with the rod shifting motor shaft; the third connecting rod 97 and the fourth connecting rod 94 are hinged, the other end of the third connecting rod 97 is hinged to the first slider 92, and the other end of the fourth connecting rod 94 is fixed to the driving shaft 96. The driving shaft 96 is driven by the rod shifting motor to rotate forward and reverse, and the force is transmitted through the third connecting rod 97 and the fourth connecting rod 94, thereby driving the first slider 92 to reciprocate on the first guide rail 91.
[0052] In the above-mentioned embodiments, a variety of connecting rod mechanisms are used to drive the movement of parts, which is convenient for adjusting the movement amount and reducing the impact. At the same time, it can avoid the rigid connection between the power providing device and the parts, thereby playing a role in protecting the power device.
[0053] Combination Fig.11The powder setting device is installed at the rear end of the truss and in front of the powder pressing device, and includes a powder setting cylinder 82, a powder setting plate 83, and a second mounting plate 84. The second mounting plate 84 is fixed on the truss 50, and the powder setting cylinder 82 is installed in the middle, and the end of the telescopic rod of the powder setting cylinder 82 is connected to the powder setting plate 83; at least one row of spacer nails is provided on the lower side of the powder setting plate 83, and each row of spacer nails is provided with a plurality of nails 85. Preferably, two rows of spacer nails are provided, and when the powder setting plate 83 is pressed down, the powder hanging rod 20 is located between the two rows of spacer nails. During operation, when the rod moving device moves the powder hanging rod 20 into place, the powder setting cylinder 82 extends to drive the powder pressing plate 83 to press down, so that the nail 85 is inserted between the rice noodles, and the rice noodles on the powder hanging rod are divided into several portions. In this way, when the powder hanging rod 20 is pulled out horizontally, the rice noodles can be prevented from being dislocated or tilted following the horizontal movement. At the same time, the nails are small at the bottom and large at the top, which can avoid breaking the rice noodles.
[0054] Preferably, it further comprises a second guide assembly 81, wherein the second guide assembly 81 is used to guide the given powder plate 83 to improve working reliability.
[0055] Combination Fig.12 The rod pulling device is installed on the right part of the truss 50, and includes a second guide rail 104, a second slider 103, a clamp 102, and a rod pulling thrust device. The second guide rail 104 is installed on the truss 50, and is equipped with the second slider 103. The rod pulling thrust device is used to drive the second slider 103 to move back and forth on the stroke of the second guide rail 104, so that the second slider 103 is close to or away from the frame 10. The clamp 102 is fixed on the second slider 103. When working, the clamp 102 clamps the right end of the powder hanging rod 20, and the rod pulling thrust device drives the second slider 103 to move away from the frame 10 (move to the right). When the left end of the powder hanging rod clamped by the clamp 102 is out of the range of the frame 10, the clamp 102 releases the powder hanging rod 20, and the powder hanging rod 20 falls into the collection frame below, and the rod pulling thrust device drives the second slider 103 to reset. Preferably, a third mounting plate 101 is further included, the upper end of the third mounting plate 101 is fixed on the second slider 103, and the lower end is connected to the clamp 102.
