Technical Field

[0001] The present invention relates to the field of conveying technology, in particular to a conveying device for processing highland barley food. Background Art

[0002] Highland barley flour is rich in dietary fiber, protein and various vitamins, which helps maintain a healthy digestive system, so it is used as food. Highland barley flour cakes, as a type of highland barley food, need to be processed into cakes and then transported to the drying room for drying using a belt conveyor. They are then processed and packaged for consumption.

[0003] After searching, the Chinese patent publication number CN218201132U discloses a highland barley noodle conveying device, including a supporting frame with a movable channel, a conveyor arranged above the supporting frame and capable of moving back and forth in the movable channel, and a driving mechanism arranged below the conveyor and connected to the supporting frame for driving the conveyor to move.

[0004] The above patent has the following shortcomings: it uses a conveyor belt to transport and then uses the conveying speed to transport the dough in a parabolic form to the lower conveyor belt. However, since the dough has a certain stickiness before drying, it easily adheres to the surface of the conveyor belt, making it impossible to transport it in a parabolic form.

[0005] Therefore, the present invention provides a conveying device for processing highland barley food. Summary of the Invention

[0006] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a conveying device for processing highland barley food.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions:

[0009] The conveyor belts are arranged in multiple equal distances, and the driven discharge roller is hollow in design. The driven discharge roller is rotatably connected to the inner side of the adjustment frame through a hollow shaft. The driven discharge roller is communicated with the inner cavity of the hollow shaft, and a convex ring is integrally formed on the outer wall of the driven discharge roller located between two adjacent conveyor belts. The side wall of the convex ring is provided with an air hole communicated with the inner cavity of the driven discharge roller.

[0010] The outer diameter of the convex ring is larger than the outer diameter of the joint between the conveyor belt and the driven discharge roller;

[0011] An air intake driving component for supplying air to the inner cavity of the driven discharge roller is provided on one side of the adjustment frame.

[0012] Preferably: the inner wall of the driven discharge roller at the position where it cooperates with the conveyor belt is radially slidably connected with multiple vibrators, and the inner side of the driven discharge roller is provided with a multi-protrusion cam that is in contact and limited cooperation with the multiple vibrators, and the multi-protrusion cam and the driven discharge roller have relative rotational motion.

[0013] Furthermore, the vibration head includes an impact head and a limit head that slide together, and springs are buckled on opposite sides of the impact head and the limit head.

[0014] Based on the above solution: the multi-protrusion cam is rotatably connected to the driven discharge roller via a connecting shaft.

[0015] A better solution among the above solutions is: an outer ring gear is fixed to the end face of the driven discharge roller, and a plurality of planetary gears are engaged on the inner side of the outer ring gear, and the planetary gears are rotatably connected to the inner wall of the adjusting frame through the planetary shaft, and the inner sides of the plurality of planetary gears are engaged with the same sun gear, and the sun gear is fixed to the outer wall of the connecting shaft.

[0016] As a further solution of the present invention: the air intake drive component includes a flexible elastic hose and an annular frame, the annular frame is fixed to the outer wall of the hollow shaft through a connecting rod, the flexible elastic hose is fixed to the outer circumferential wall of the annular frame, and the side wall of the adjustment frame is rotatably connected to a plurality of extrusion rollers, the extrusion rollers contact and squeeze the outer wall of the flexible elastic hose, the air outlet of the flexible elastic hose is connected to the outer wall of the hollow shaft and the flexible elastic hose is connected to the inner cavity of the driven discharge roller through the inner cavity of the hollow shaft.

[0017] At the same time, a motor is fixed to an outer wall of one side of the adjustment frame, and the output shaft of the motor is driven to cooperate with the side wall of the active feeding wheel to rotate and drive the active feeding wheel.

[0018] As a preferred embodiment of the present invention, the lifting mechanism includes a rotating frame 1 and a rotating frame 2, the bottom end of the rotating frame 1 is rotatably connected to the outer wall of the base frame, and the other end of the rotating frame 1 is rotatably connected to the bottom of one side of the adjustment frame.

[0019] At the same time, the bottom end of the rotating frame 2 is rotatably connected to the outer wall of the base frame, and the other end of the rotating frame 2 is rotatably connected to the support roller through a roller shaft. A plurality of limit frames are fixed to the bottom outer wall of the adjustment frame, and the support roller is provided with a plurality of limit grooves on its side wall to roll and limit the outer wall of the limit frame.

[0020] As a more preferred solution of the present invention: both sides of the base frame are rotatably connected with a telescoping device 1 and a telescoping device 2, and the telescopic ends of the telescoping device 1 and the telescoping device 2 are rotatably connected to the rotating frame 1 and the telescoping device 2 respectively.

[0021] The beneficial effects of the present invention are:

[0022] 1. The present invention, on the one hand, arranges the conveyor belt into a plurality of parallel combinations, which can form a "hollow" conveying support, thereby reducing the adhesion area between the dough cake and the conveyor belt. At the same time, by providing a large-diameter convex ring and coordinating the exhaust of the air holes, the dough cake at the hollow support can be lifted up and blown toward the dough cake by the action of the air flow, and blown into the gap between the conveyor belt and the dough cake along the ground diversion of the dough cake, thereby effectively preventing adhesion and ensuring that the dough cake is reliably discharged in a parabolic shape.

[0025] 4. The present invention utilizes a flexible elastic hose and an extrusion roller for air supply. On the one hand, a simple structure can replace a "pump", thereby reducing the power source layout and achieving a higher start-stop synchronization of the entire device. On the other hand, since the hollow shaft rotates continuously, the flexible elastic hose serving as the air supply pipeline rotates synchronously with the hollow shaft, thereby effectively preventing the pipeline entanglement problem caused by the rotation of the hollow shaft compared to traditional air supply.

[0037] The technical solution of the present invention will be further described in detail below in conjunction with specific implementation methods.

[0038] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0039] Example 1:

[0040] A conveying device for highland barley food processing, such as Figures 1-9 As shown, it includes a base frame 1, the top of the base frame 1 is driven by a lifting mechanism 7 to cooperate with an adjusting frame 3, the inner walls of the feed side and the discharge side of the adjusting frame 3 are respectively rotated to cooperate with an active feed wheel 6 and a driven discharge roller 2, and the outer sides of the active feed wheel 6 and the driven discharge roller 2 are driven to cooperate with a conveyor belt 4.

[0041] The conveyor belts 4 are arranged in multiple equidistant positions, and the driven discharge roller 2 is hollow in design. The driven discharge roller 2 is rotatably connected to the inner side of the adjustment frame 3 through a hollow shaft 8. The driven discharge roller 2 is connected to the inner cavity of the hollow shaft 8, and the outer wall of the driven discharge roller 2 located between two adjacent conveyor belts 4 is integrally formed with a convex ring 9, and the side wall of the convex ring 9 is provided with an air hole 10 connected to the inner cavity of the driven discharge roller 2.

[0042] The outer diameter of the convex ring 9 is larger than the outer diameter of the portion where the conveyor belt 4 and the driven discharge roller 2 fit together.

[0043] An air intake drive member 16 for supplying air to the inner cavity of the driven discharge roller 2 is provided on one side of the adjustment frame 3 .

[0044] When the device is in use, the highland barley cake can be placed on the conveyor belt 4 from the side of the active feed wheel 6, and the driven discharge roller 2, the conveyor belt 4, and the active feed wheel 6 move together to transport the cake. When the cake is transported to the driven discharge roller 2, since the outer diameter of the convex ring 9 is larger than the outer diameter of the fitting point between the conveyor belt 4 and the driven discharge roller 2, the cake located between the conveyor belt 4 will be pushed upward by the driven discharge roller 2, and at the same time, the air intake drive 16 will supply air to the inner cavity of the driven discharge roller 2, and the gas is discharged through the air intake drive 16.

[0045] On the one hand, this device arranges the conveyor belt 4 into a plurality of parallel combinations, which can form a "hollowed-out" conveying support, thereby reducing the adhesion area between the dough and the conveyor belt 4. At the same time, by setting a large-diameter convex ring 9 and coordinating the exhaust of the air hole 10, the dough at the hollow support can be lifted up and blown toward the dough by the air flow, and blown into the gap between the conveyor belt 4 and the dough along the ground guide of the dough, thereby effectively preventing adhesion and ensuring that the dough is reliably discharged in a parabolic shape.

[0046] In order to further solve the adhesion problem; Figure 3 、 Figure 4 、 Figure 5 As shown, the inner wall of the driven discharge roller 2 at the position where it cooperates with the conveyor belt 4 is radially slidably connected with multiple vibrating heads 11, and the inner side of the driven discharge roller 2 is provided with a multi-protrusion cam 12 that is in contact and limited cooperation with the multiple vibrating heads 11, and the multi-protrusion cam 12 and the driven discharge roller 2 have relative rotational motion.

[0047] The vibration head 11 includes a striking head 13 and a limiting head 15 that are slidably engaged with each other, and a spring 14 is buckled on opposite sides of the striking head 13 and the limiting head 15 .

[0048] When the driven discharge roller 2 rotates and conveys, since the multi-protrusion cam 12 and the driven discharge roller 2 have relative rotational motion, the vibration head 11 and the multi-protrusion cam 12 also have relative rotational motion. When the vibration head 11 is engaged with the protruding part of the multi-protrusion cam 12, the multi-protrusion cam 12 will apply an outward limiting force to the vibration head 11, so that the impact head 13 first hits the conveyor belt 4 outward, and then the limiting head 15 continues to move outward, the spring 14 is compressed, and then hits the impact head 13.

[0049] This device, by setting a vibration head 11 and utilizing the limiting effect of the multi-protrusion cam 12 on the vibration head 11, can make the vibration head 11 produce an impact on the conveyor belt 4, thereby utilizing the impact vibration to assist the airflow to release adhesion. At the same time, by setting the vibration head 11 as a combination of the impact head 13, the spring 14, and the limiting head 15, the vibration head 11 can produce two collisions in a single time by cooperating with the protrusion of the multi-protrusion cam 12, thereby increasing the collision frequency and further preventing adhesion.

[0050] In order to further solve the adhesion problem; Figure 7 As shown, the multi-protrusion cam 12 is rotatably connected to the driven discharge roller 2 via a connecting shaft 17. An outer gear ring 22 is fixed to the end face of the driven discharge roller 2. A plurality of planetary gears 23 are meshed on the inner side of the outer gear ring 22. The planetary gears 23 are rotatably connected to the inner wall of the adjusting frame 3 via planetary shafts 24. The inner sides of the plurality of planetary gears 23 are meshed with the same sun gear 25, and the sun gear 25 is fixed to the outer wall of the connecting shaft 17.

[0051] When the driven discharge roller 2 rotates, it can drive the outer ring gear 22 to rotate, thereby driving the sun gear 25 to rotate in the opposite direction through the planetary gears 23 .

[0052] This device, on the basis of realizing the vibration and adhesion prevention of the conveyor belt 4 by setting a multi-lobe cam 12, sets the multi-lobe cam 12 and the air hole 10 to be movably connected, and at the same time adds components such as the outer ring gear 22, the planetary gear 23, and the sun gear 25. On the one hand, it can increase the rotational movement speed between the driven discharge roller 2 and the multi-lobe cam 12, increase the impact vibration frequency, and further prevent adhesion. On the other hand, it also realizes comprehensive drive and increases synchronization.

[0053] In order to solve the airflow drive problem; Figure 5 、 6 As shown, the air intake drive 16 includes a flexible elastic hose 18 and an annular frame 20, the annular frame 20 is fixed to the outer wall of the hollow shaft 8 by a connecting rod 21, the flexible elastic hose 18 is fixed to the outer circumferential wall of the annular frame 20, and the side wall of the adjustment frame 3 is rotatably connected to a plurality of squeezing rollers 19, the squeezing rollers 19 contact and squeeze fit with the outer wall of the flexible elastic hose 18, the air outlet of the flexible elastic hose 18 is connected to the outer wall of the hollow shaft 8 and the flexible elastic hose 18 is connected to the inner cavity of the driven discharge roller 2 through the inner cavity of the hollow shaft 8.

[0054] When the hollow shaft 8 rotates, it can drive the annular frame 20 and the flexible elastic hose 18 to rotate, so that the flexible elastic hose 18 and the squeezing roller 19 have relative movement. During the relative movement, the squeezing roller 19 will squeeze the flexible elastic hose 18, squeezing the air in the flexible elastic hose 18 into the inner cavity of the hollow shaft 8, and then transporting it to the inner cavity of the driven discharge roller 2. The squeezed flexible elastic hose 18 rebounds due to its own elastic force, and then sucks in air from the other end, thus completing the cycle.

[0055] This device supplies air by utilizing a flexible elastic hose 18 and an extrusion roller 19. On the one hand, it replaces the "pump" through a simple structure, reduces the power source layout, and also enables the start-stop synchronization of the entire device to be higher. On the other hand, since the hollow shaft 8 rotates continuously, the flexible elastic hose 18 serving as the air supply pipeline rotates synchronously with the hollow shaft 8, thereby effectively preventing the pipeline entanglement problem caused by the rotation of the hollow shaft 8 compared to the traditional air supply.

[0056] A motor 5 is fixed to an outer wall of one side of the adjustment frame 3 , and the output shaft of the motor 5 is coupled to the side wall of the active feeding wheel 6 to rotate and drive the active feeding wheel 6 .

[0057] Universal wheels 29 with brakes are provided at the four corners of the bottom of the chassis 1 .

[0058] When the present embodiment is in use, the highland barley flour cake can be placed on the conveyor belt 4 from one side of the active feed wheel 6, and the driven discharge roller 2, the conveyor belt 4 and the active feed wheel 6 move together to transport the flour cake. When the flour cake is transported to the driven discharge roller 2, since the outer diameter of the convex ring 9 is larger than the outer diameter of the matching part of the conveyor belt 4 and the driven discharge roller 2, the flour cake between the conveyor belt 4 will be pushed upward by the driven discharge roller 2. At the same time, when the hollow shaft 8 rotates, it can drive the annular frame 20 and the flexible elastic hose 18 to rotate, so that the flexible elastic hose 18 and the squeezing roller 19 have relative movement. During the relative movement, the squeezing roller 19 will squeeze the flexible elastic hose 18, The air in the elastic hose 18 is squeezed into the inner cavity of the hollow shaft 8 and then transported to the inner cavity of the driven discharge roller 2. The flexible elastic hose 18 after being squeezed rebounds due to its own elastic force and then sucks in air from the other end, thus completing the cycle. In addition, when the driven discharge roller 2 rotates, it can drive the outer ring gear 22 to rotate, thereby driving the sun gear 25 to rotate in the opposite direction through the planetary gear 23. When the vibrating head 11 is engaged with the convex part of the multi-convex cam 12, the multi-convex cam 12 will apply an outward limiting force to the vibrating head 11, so that the impact head 13 first hits the conveyor belt 4 outward, and then the limiting head 15 continues to move outward, the spring 14 is compressed, and then hits the impact head 13.

[0059] Example 2:

[0060] A conveying device for highland barley food processing, such as Figure 1 、 Figure 8 、 Figure 9 As shown, in order to solve the problem of adjusting the conveying height angle; this embodiment makes the following improvements on the basis of Example 1: the lifting mechanism 7 includes a rotating frame 26 and a rotating frame 28, the bottom end of the rotating frame 26 is rotatably connected to the outer wall of the base frame 1, and the other end of the rotating frame 26 is rotatably connected to the bottom of one side of the adjustment frame 3, the bottom end of the rotating frame 28 is rotatably connected to the outer wall of the base frame 1, and the other end of the rotating frame 28 is rotatably connected to the support roller 32 through the roller shaft 31, and a plurality of limit frames 34 are fixed to the bottom outer wall of the adjustment frame 3, and the support roller 32 is provided with a plurality of limit grooves 33 on its side wall to roll and limit the outer wall of the limit frame 34.

[0061] The two sides of the base frame 1 are rotatably connected to the telescopic device 1 27 and the telescopic device 2 30 , and the telescopic ends of the telescopic device 1 27 and the telescopic device 2 30 are rotatably connected to the rotating frame 1 26 and the telescopic device 2 30 .

[0062] When the present embodiment is in use, when the telescopic device 1 27 or the telescopic device 2 30 is extended or retracted, it can drive the rotating frame 1 26 or the rotating frame 2 28 to rotate, thereby changing the angle or height of the adjustment frame 3. When the rotating frame 1 26 and the rotating frame 2 28 rotate synchronously and in opposite directions, the adjustment frame 3 will rise and fall linearly. When the rotating frame 1 26 and the rotating frame 2 28 rotate asynchronously and in opposite directions, the adjustment frame 3 will tilt at an angle.

[0063] This device, by providing a lifting mechanism 7, which is composed of a rotating frame 1 26, a rotating frame 2 28, a telescopic device 1 27, and a telescopic device 2 30, can utilize the telescopic movement of the rotating frame 1 26 and the rotating frame 2 28 to achieve the lifting and lowering adjustment of the adjustment frame 3 and the adjustment of the conveying angle of the adjustment frame 3, thereby adapting to different conveying requirements and increasing the practical convenience of the device. The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed by the present invention, makes equivalent substitutions or changes based on the technical solution and inventive concept of the present invention should be covered by the protection scope of the present invention.
