Abstract

This invention relates to the technical field of packaging structures, and in particular to an auxiliary structure for corn starch packaging, comprising a feeding pipe, a support plate disposed at the output end of the feeding pipe, and a rotating drum coaxially rotatably disposed on the support plate. The axis of the support plate is horizontal, and the rotating drum is connected to the output end of the feeding pipe. By limiting the direction of the movable hopper during the packaging process, its opening can always face downward and correspond to the opening of the packaging bag during filling, thereby facilitating the automatic insertion of the movable hopper into the packaging bag for filling. Furthermore, the vertical movement of the movable hopper can be driven by the rotating drum, allowing the movable hopper to move horizontally synchronously with the packaging bag when discharging corn starch, thus achieving a dynamic filling mode. This eliminates the need for separate control of the vertical movement of the movable hopper and repeated control of equipment start and stop, improving the continuity of corn starch packaging operations, reducing operation steps, and increasing work efficiency.

Description

Technical Field

[0001] This invention relates to the technical field of packaging structures, and in particular to an auxiliary structure for corn starch packaging. Background Technology

[0002] In the industrial packaging production of corn starch, bulk starch is usually quantitatively filled into flexible packaging bags. Existing packaging equipment generally adopts an intermittent operation mode. First, multiple packaging bags are grabbed one by one by a mechanical clamping device and pre-expanded so that they are arranged horizontally and conveyed sequentially along the conveying path. When the packaging bag is conveyed to the storage hopper at a fixed position, the conveying mechanism stops running, so that the packaging bag stops accurately at the filling station. Then, the drive device controls the hopper to move vertically downward, so that its outlet is inserted into the packaging bag, the valve is opened and the starch is quantitatively filled. After filling is completed, the hopper is closed and lifted back to its original position. The conveying mechanism restarts, moves the next packaging bag into the station, and repeats the above feeding and lifting actions.

[0003] However, this type of structural design means that the entire packaging process must rely on repeated start-stop operations and the reciprocating lifting and lowering of the hopper. The fixed waiting time of the packaging bag at the filling station and the empty travel of the hopper directly occupy a lot of time. This intermittent packaging mode makes it impossible for the hopper to continuously discharge material, and the conveying link is also difficult to achieve continuous flow operation. The overall working continuity of the equipment is significantly insufficient, the processing capacity per unit time is limited, and it is difficult to meet the needs of large-scale, high-efficiency continuous packaging. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides an auxiliary structure for corn starch packaging, the specific technical solution of which is as follows: An auxiliary structure for corn starch packaging according to the present invention includes a feeding pipe, a support plate disposed at the output end of the feeding pipe, and a rotating cylinder coaxially rotatably disposed on the support plate. The axis of the support plate is horizontal, and the rotating cylinder is connected to the output end of the feeding pipe. A plurality of fixed material pipes are disposed in the circumferential direction on the outer wall of the rotating cylinder. Each fixed material pipe is rotatably disposed with a movable hopper, and the movable hopper, the fixed material pipes, and the interior of the rotating cylinder are sequentially connected. The movable hopper's rotation axis on the fixed material pipe is parallel to the axis of the support plate. The material conveying pipe is provided with a back plate, and a guide groove is provided on the back plate. Each movable hopper is provided with a guide post for use with the guide groove. The guide groove guides the movable hopper through the guide post, so that the opening of the movable hopper faces downward during the rotation of the drum.

[0005] Furthermore, the guide groove is an annular shape that mates with the support plate. The guide groove includes two variable diameter arc grooves, two transition arc grooves, and two inclined grooves that are distributed opposite to each other on the left and right sides of the axis of the support plate. The two inclined grooves are connected by a reversing arc groove. The distance between any position on the variable diameter arc groove and the axis of the support plate gradually changes. The transition arc groove and the reversing arc groove are both coaxially arranged with the support plate. An auxiliary structure is provided on the back plate for use in conjunction with the reversing arc groove and for pushing the movable hopper from one side of the fixed material tube to the other side.

[0006] Furthermore, the auxiliary structure includes a side pusher that is slidably disposed on the back plate along the radial direction of the support plate. The side pusher is connected to the back plate by an elastic body. The side pusher is provided with an extrusion surface and a side pusher surface that cooperate with the guide post.

[0007] Furthermore, two baffles are arranged opposite each other on the support plate, and during the rotation of the rotating drum, the baffles block the connection between the rotating drum and the fixed material pipe.

[0008] Furthermore, the back plate is provided with a slider that slides along the radial direction of the support plate. A power shaft is rotatably mounted on the slider, and a transmission wheel is eccentrically mounted on the power shaft. During the part of the process in which the transmission wheel makes transmission contact with the outer wall of the rotating drum and causes the rotating drum to rotate, the moving speed of the movable hopper in the horizontal direction is constant.

[0009] Furthermore, the rotating drum is vibratingly mounted on the support plate, and the vibration direction of the rotating drum is along the axial direction of the support plate.

[0010] Furthermore, a circular groove is formed on the outer wall of the rotating cylinder, and two connecting seats are slidably arranged in the circular groove. The slider and the connecting seats are rotatably connected by an inclined push-pull arm.

[0011] Furthermore, the slider and the back plate are connected by an elastic body 2; A motor is provided on the back plate, and a prism shaft is provided at the output end of the motor. An auxiliary sleeve is slidably sleeved on the prism shaft, and a worm gear is provided on the auxiliary sleeve. A worm wheel that works with the worm gear is provided on the power shaft. The auxiliary sleeve and the slider are connected by a connecting frame.

[0012] The beneficial effects of this invention are as follows: By defining the direction of the movable hopper during the packaging process, its opening always faces downwards and aligns with the opening of the packaging bag during filling. This facilitates the automatic insertion of the movable hopper into the packaging bag for filling. Furthermore, the vertical movement of the movable hopper is driven by a rotating drum, allowing it to move horizontally in sync with the packaging bag when discharging corn starch. This achieves a dynamic filling mode, eliminating the need for separate control of the movable hopper's vertical movement and repeated start-stop control of the equipment. This improves the continuity of corn starch packaging operations, reduces operational steps, and increases work efficiency. Attached Figure Description

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0016] In the description of this invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0017] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. This embodiment is written in a progressive manner.

[0018] like Figures 1 to 6 As shown, an auxiliary structure for corn starch packaging according to the present invention includes a feeding pipe 1, a support plate 2 disposed at the output end of the feeding pipe 1, and a rotating cylinder 3 coaxially rotatably disposed on the support plate 2. The axis of the support plate 2 is horizontal, and the rotating cylinder 3 is connected to the output end of the feeding pipe 1. Several fixed material pipes 4 are disposed in the circumferential direction on the outer wall of the rotating cylinder 3. Each fixed material pipe 4 is rotatably disposed on a movable hopper 5, and the movable hopper 5, the fixed material pipes 4 and the interior of the rotating cylinder 3 are connected in sequence. Among them, the rotation axis of the movable hopper 5 on the fixed material pipe 4 is set parallel to the axis of the support plate 2. The material conveying pipe 1 is provided with a back plate 7, and a guide groove 8 is opened on the back plate 7. Each movable hopper 5 is provided with a guide post 6 for use in conjunction with the guide groove 8. The guide groove 8 guides the movable hopper 5 through the guide post 6, so that the opening of the movable hopper 5 faces downward during the rotation of the rotating drum 3.

[0019] In this invention, both the support plate 2 and the rotating drum 3 are horizontally aligned and coaxially arranged. Thus, when the rotating drum 3 rotates, the movement trajectories of the rotating drum 3 and its several fixed material pipes 4 and several movable hoppers 5 are on a vertical plane. The movable hoppers 5 can move sequentially to the lower area of ​​the rotating drum 3 and discharge the starch. The output end of the conveying pipe 1 can pass through the support plate 2 and connect with the rotating drum 3. The support plate 2 provides support for the rotating drum 3. To meet the requirements of the lateral conveying trajectory of the external packaging bag, the rotation axis of the movable hopper 5 on the fixed material pipe 4 needs to be parallel to the axis of the support plate 2. In this way, the movement trajectory of the movable hopper 5 on the fixed material pipe 4 and the movement trajectory of the external packaging bag can be on the same vertical plane.

[0020] In use, the rotating drum 3 can rotate on the support plate 2. At the same time, the rotating drum 3 drives several fixed material pipes 4 and several movable hoppers 5 on it to move in a synchronous circular motion. The movable hoppers 5 can drive the guide columns 6 to slide in the guide grooves 8. The guide grooves 8 and the guide columns 6 guide the movable hoppers 5 synchronously, so that when the movable hoppers 5 move to the lower area of ​​the rotating drum 3, the opening of the movable hoppers 5 always faces downward. When the outer packaging bag is conveyed horizontally, the packaging bag gradually moves to a position close to the rotating drum 3. At this time, the corresponding movable hoppers 5 on the rotating drum 3 move down, and the movable hoppers 5 open. With the opening facing downwards, as the rotating drum 3 rotates, the movable hopper 5 gradually moves downwards in the vertical direction, and the opening of the movable hopper 5 gradually inserts into the packaging bag. The starch material in the conveying pipe 1 is introduced into the rotating drum 3 and filled into the packaging bag through the fixed material pipe 4 and the movable hopper 5. When the movable hopper 5 reaches the lowest point of the rotating drum 3, the movable hopper 5 gradually moves upwards in the vertical direction. After filling is completed, the movable hopper 5 separates from the packaging bag, thus completing the packaging work. In the above process, the opening of the movable hopper 5 always faces downwards and corresponds to the opening of the packaging bag.

[0021] By limiting the direction of the movable hopper 5 during the packaging process, its opening can always face downwards and correspond to the opening of the packaging bag during filling. This facilitates the automatic insertion of the movable hopper 5 into the packaging bag for filling. Furthermore, the vertical movement of the movable hopper 5 can be driven by the rotating drum 3, allowing the movable hopper 5 to move horizontally synchronously with the packaging bag when discharging corn starch. This achieves a dynamic filling mode, eliminating the need to separately control the vertical movement of the movable hopper 5 and repeatedly control the start and stop of the equipment. This improves the continuity of corn starch packaging operations, reduces operational steps, and increases work efficiency.

[0022] Furthermore, the guide groove 8 is an annular shape that cooperates with the support plate 2. The guide groove 8 includes two variable diameter arc grooves 9, two transition arc grooves 10 and two inclined grooves 11 that are distributed opposite to each other on the left and right sides of the axis of the support plate 2. The two inclined grooves 11 are connected by a reversing arc groove 12. The distance between any position on the variable diameter arc groove 9 and the axis of the support plate 2 gradually changes. The transition arc grooves 10 and the reversing arc grooves 12 are both coaxially arranged with the support plate 2. An auxiliary structure is provided on the back plate 7 for use with the reversing arc groove 12 to push the movable hopper 5 from one side of the fixed material tube 4 to the other side.

[0023] like Figure 3 As shown, the bottoms of the two variable-diameter arc grooves 9 are connected below the axis of the support plate 2. The tops of the two variable-diameter arc grooves 9 are connected to the bottoms of the two transition arc grooves 10, and the tops of the two transition arc grooves 10 are connected to the bottoms of the two inclined grooves 11. The two inclined grooves 11 are connected by a reversing arc groove 12, thus forming a guide groove 8 to facilitate the rotational movement of the guide column 6 and the rotating drum 3. When the guide column 6 moves upward or downward in the variable-diameter arc groove 9, the distance between the guide column 6 and the axis of the support plate 2 gradually decreases or increases. At this time, the variable-diameter arc groove 9 guides the guide column 6 and pushes the movable hopper 5 to rotate on the fixed material pipe 4 through the guide column 6, so that the opening of the movable hopper 5 always faces downward. Specifically, when the guide column 6 moves downward from the right variable-diameter arc groove 9, the distance between the guide column 6 and the axis of the support plate 2 gradually increases, and the angle between one side of the movable hopper 5 and the fixed material pipe 4 gradually increases. When the movable hopper 5 moves to the lower side of the support plate 2, the movable hopper 5... The hopper 5 is collinear with the fixed material pipe 4. As the rotating drum 3 continues to rotate, and with the help of gravity, the guide column 6 on the movable hopper 5 moves upward in the left-side variable diameter arc groove 9. The movable hopper 5 rotates to the right on the fixed material pipe 4, and the angle between the other side of the movable hopper 5 and the fixed material pipe 4 gradually decreases, thereby controlling the opening direction of the movable hopper 5. When the guide column 6 moves into the left-side transition arc groove 10, the movable hopper 5 maintains the angle with the fixed material pipe 4 and rotates. When the guide column 6 passes through the two inclined grooves 11 and the reversing arc groove 12, the auxiliary structure pushes the movable hopper 5 from one side of the fixed material pipe 4 to the other side, causing the movable hopper 5 to tilt towards the other side on the fixed material pipe 4. When the guide column 6 moves into the right-side transition arc groove 10, the movable hopper 5 maintains this tilted state and rotates synchronously with the fixed material pipe 4. When the movable hopper 5 moves into the right-side variable diameter arc groove 9 again, the movable hopper 5 resumes the filling operation.

[0024] Furthermore, the auxiliary structure includes a side pusher 13 that is slidably disposed on the back plate 7 along the radial direction of the support plate 2. The side pusher 13 is connected to the back plate 7 by an elastic body 14. The side pusher 13 is provided with a pressing surface 15 and a side pusher surface 16 that cooperate with the guide post 6.

[0025] The side pusher 13 is located above the support plate 2. The elastic body 14 provides elastic thrust to the side pusher 13. When the guide column 6 contacts the extrusion surface 15, the rotating drum 3 can push the side pusher 13 downward through the guide column 6 and the extrusion surface 15. At this time, the elastic body 14 undergoes elastic deformation, the guide column 6 moves in the left inclined groove 11, and the included angle between the movable hopper 5 and the fixed material pipe 4 gradually increases. When the guide column 6 moves from the extrusion surface 15 to the side pusher surface 16, the elastic body 14 can be pushed downward through the side pusher. The side push surface 16 provides auxiliary thrust to the guide column 6. At this time, the guide column 6 moves from the left inclined groove 11 to the reversing arc groove 12, and the movable hopper 5 and the fixed material pipe 4 are collinear. Since the reversing arc groove 12 is coaxially set with the support plate 2, the auxiliary thrust provided by the side push surface 16 to the guide column 6 can make the movable hopper 5 biased to the right side of the fixed material pipe 4 when the guide column 6 enters the right inclined groove 11, thereby pushing the movable hopper 5 from one side of the fixed material pipe 4 to the other side, realizing the reversal of the movable hopper 5.

[0026] Furthermore, two baffles 17 are arranged opposite each other on the support plate 2. During the rotation of the rotating drum 3, the baffles 17 block the connection between the rotating drum 3 and the fixed material pipe 4.

[0027] During the rotation of the drum 3, starch material is continuously introduced into the drum 3 through the feeding pipe 1. Therefore, when the movable hopper 5 separates from the outer packaging bag, the drum 3 needs to stop continuously introducing material into the fixed feeding pipe 4 to prevent material from scattering outward through the opening of the movable hopper 5 and causing waste. That is, when the movable hopper 5 moves to the fixed position, the baffle 17 needs to be used to block the fixed feeding pipe 4. At this time, the movable hopper 5 has not yet separated from the packaging bag, and the material remaining in the fixed feeding pipe 4 and the movable hopper 5 can continue to flow out. The relative arrangement of the two baffles 17 can only allow material to be introduced into the movable hopper 5 from the drum 3 when the movable hopper 5 moves to the lower area of ​​the drum 3. Of course, a baffle 17 with a larger arc can also be set to limit the feeding position and stopping position of the drum 3 to the fixed feeding pipe 4.

[0028] Furthermore, a slider 18 is provided on the back plate 7, which slides along the radial direction of the support plate 2. A power shaft 19 is rotatably provided on the slider 18. A transmission wheel 20 is eccentrically provided on the power shaft 19. During the part of the transmission wheel 20 making transmission contact with the outer wall of the rotating drum 3 and causing the rotating drum 3 to rotate, the moving speed of the movable hopper 5 in the horizontal direction is constant.

[0029] The power shaft 19 provides power to the rotation of the drum 3 through the transmission wheel 20. Since the power shaft 19 and the transmission wheel 20 are eccentrically set, the distance between the power shaft 19 and the support plate 2 will repeatedly change along the radial direction of the support plate 2. At this time, the power shaft 19 can push the slider 18 to slide on the back plate 7. The eccentric setting of the power shaft 19 and the transmission wheel 20 can make the distance between any position on the transmission wheel 20 and the axis of the power shaft 19 unequal, so that the transmission ratio between the power shaft 19 and the drum 3 can change at all times. This can change the horizontal moving speed of the movable hopper 5 during the filling operation, so that the movable hopper 5 and the outer packaging bag can move synchronously.

[0030] In some embodiments, since the opening of the packaging bag is generally larger than the opening of the movable hopper 5, the movable hopper 5 can be allowed to move within a small range relative to the packaging bag, as long as the opening of the movable hopper 5 can be kept inside the packaging bag. This facilitates the processing of the transmission wheel 20, allows for a certain degree of error, and the outer wall of the transmission wheel 20 can be set to consist of two arcs with gradually changing curvature, so that the horizontal moving speed of the movable hopper 5 is kept within a specified range when it moves to the lower side of the rotating drum 3.

[0031] Furthermore, the rotating drum 3 can be vibrated on the support plate 2, and the vibration direction of the rotating drum 3 is along the axis of the support plate 2.

[0032] When the baffle 17 blocks the fixed material pipe 4, or when the fixed material pipe 4 and the movable hopper 5 are discharging material, in order to avoid material blockage of the fixed material pipe 4 and the movable hopper 5, the rotating drum 3 can be vibrated to facilitate the material being shaken out and avoid blockage. At the same time, in order to avoid this vibration interfering with the movement trajectory of the rotating drum 3, the fixed material pipe 4 and the movable hopper 5, the vibration direction can be made along the axis of the support plate 2.

[0033] It should be noted that if the vibration direction of the rotating drum 3 is along its own circumference, the vibration will interfere with the movement of the guide column 6 in the guide groove 8. For example, when the guide column 6 moves in the variable diameter arc groove 9, the vibration will continuously change the distance between the guide column 6 and the axis of the support plate 2, thereby causing the movable hopper 5 to swing back and forth on the fixed material pipe 4. This swing will affect the strength and service life of the equipment.

[0034] Furthermore, a circular groove is provided on the outer wall of the rotating cylinder 3, and two connecting seats 22 are slidably arranged in the circular groove. The slider 18 and the connecting seats 22 are rotatably connected by an inclined push-pull arm 21.

[0035] like Figure 3 and Figure 5As shown, when the slider 18 reciprocates along the radial direction of the support plate 2, the slider 18 can drive the connecting seat 22 to reciprocate along the axis of the support plate 2 through the push-pull arm 21, thereby causing the rotating drum 3 to vibrate on the support plate 2. Since the connecting seat 22 is slidably connected to the rotating drum 3 through the circular groove, the connecting seat 22 will not interfere with the rotation of the rotating drum 3.

[0036] Furthermore, the slider 18 is connected to the back plate 7 by an elastic body 23; A motor 24 is provided on the back plate 7. A prism shaft 27 is provided at the output end of the motor 24. An auxiliary sleeve 28 is slidably sleeved on the prism shaft 27. A worm gear 25 is provided on the auxiliary sleeve 28. A worm wheel 26 that works with the worm gear 25 is provided on the power shaft 19. The auxiliary sleeve 28 and the slider 18 are connected by a connecting frame 29.

[0037] When the power shaft 19 drives the transmission wheel 20 and the rotating drum 3 to rotate, the rotating drum 3 can push the power shaft 19 and the slider 18 to move radially along the support plate 2 in the opposite direction through the transmission wheel 20. The elastic body 23 can provide a restoring force for the slider 18 and the power shaft 19, so that the transmission wheel 20 and the rotating drum 3 remain in close contact. The motor 24 can drive the worm wheel 26 to rotate through the prism shaft 27, the auxiliary sleeve 28 and the worm 25, thereby driving the power shaft 19 to rotate. The movement of the power shaft 19 and the slider 18 will be transmitted to the auxiliary sleeve 28 and the worm 25 through the connecting frame 29, so that the worm wheel 26 and the worm 25 can move synchronously with the slider 18. The worm wheel 26 and the worm 25 maintain a constant transmission ratio movement, and the auxiliary sleeve 28 slides on the prism shaft 27.

[0038] Since the auxiliary sleeve 28 and the worm gear 25 rotate with the prism shaft 27, the connecting bracket 29 needs to be rotatably connected to the auxiliary sleeve 28.

[0039] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
