Description

Technical Field

[0001] This application relates to the field of spiral conveying technology, and in particular to a double spiral vertical conveying device for square materials. Background Technology

[0002] It is known that in some food processing plants, production lines are usually located on the factory floor during actual operation, especially in the packaging workshop. After items are packaged in square cardboard boxes, they need to be packed and transported, such as in corrugated cardboard boxes.

[0003] Given that the floor space in the packaging workshop of a factory is limited, the entire factory area is usually a single-story building, with each floor responsible for a corresponding production. To facilitate the packaging of goods, the production line after packaging and the packaged boxes being loaded onto trucks are usually arranged in a continuous assembly line. However, this situation inevitably requires a larger factory area, on the one hand to facilitate the movement of transport vehicles, on the other hand to facilitate box packing, and at the same time, forklifts need to be able to operate between the packaging station and the transport station.

[0004] To ensure more convenient operation within a limited factory area, existing manufacturers typically set up packaging and transportation workstations on adjacent floors. While this effectively solves the problem of unreasonable division of packaging and transportation areas, it also greatly inconveniences the need to transport items between the two workstations via handcarts to the elevator. Summary of the Invention

[0005] To improve the problem of inconvenient packaging and transportation between two workstations, this application provides a double-helix vertical conveying device for square materials.

[0006] The technical solution of the double-helix vertical conveying device for square materials provided in this application is as follows:

[0007] A double-helix vertical conveying device for square materials includes a support frame with an inlet at one end and an outlet at the other. Two main shafts are rotatably mounted in the support frame, one of which has a left helical plate fixed to it and the other has a right helical plate fixed to it. A baffle rod for preventing material slippage is fixed inside the support frame. A vertical conveying zone is formed between the left and right helical plates and the baffle rod. The support frame is also equipped with a drive assembly for driving the two main shafts to rotate synchronously in opposite directions. When square materials are placed in the vertical conveying zone, the drive assembly drives the left and right helical plates to rotate synchronously in opposite directions, thereby pushing the square materials linearly along the length of the baffle rod.

[0008] By adopting the above technical solution, when facing situations where square materials need to be conveyed between two workstations, such as material conveying between workstations on two adjacent floors, or to facilitate the unobstructed passage of workers in the processing workshop, etc., when material conveying is required, the square material is placed in the handling and conveying area through the feed port. Under the weight of the box itself and the limiting of the left and right spiral plates, the two main shafts are driven to rotate synchronously in opposite directions by the drive component, thereby lifting the square material and conveying it to another workstation, improving the convenience of material conveying.

[0009] Optionally, one end of the bracket is provided with a first mounting base, and the other end of the bracket is provided with a second mounting base. One end of the two main shafts is rotatably connected to the first mounting base, and the other end of the two main shafts is rotatably connected to the second mounting base. The drive assembly is provided on the second mounting base, and the bracket is provided with an adjustment assembly for adjusting the distance between the main shafts and the stop bar.

[0010] By adopting the above technical solutions, we can adapt to square materials of different sizes, thereby improving the applicability and working efficiency of the conveying equipment.

[0011] Optionally, both the first mounting base and the second mounting base are slidably connected to the bracket, and the adjustment assembly includes a lead screw rotatably connected to the bracket and a connecting block fixed to the side wall of the second mounting base, wherein the connecting block is threadedly connected to the lead screw.

[0012] By adopting the above technical solution, the first and second mounting seats on the support can be slidably connected along the support, and the distance between the main shaft and the stop bar can be adjusted by the threaded engagement of the lead screw and the connecting block. This makes it easy to adjust the conveying space according to square materials of different sizes, thereby improving the adaptability and flexibility of the equipment.

[0013] Optionally, the drive assembly includes a first gear coaxially fixed on one of the rotating shafts, a second gear coaxially fixed on the other rotating shaft, a motor fixed on a second mounting base, and a drive gear fixed on the motor shaft. The drive gear meshes with the first gear, and the first gear meshes with the second gear.

[0014] By adopting the above technical solution, the rotation of the motor shaft is controlled, so that the drive gear meshes with the first gear and rotates, and the first gear meshes with the second gear and rotates synchronously in opposite directions, thereby ensuring that the left and right spiral plates can effectively push the square material in a straight line along the length of the baffle.

[0015] Optionally, a guide plate is rotatably provided at both the inlet and outlet, and a spring plunger is installed on the side wall of the guide plate, with the ball head of the spring plunger abutting against the side wall of the bracket.

[0016] By adopting the above technical solution, it is easy to adjust the tilt angle of the guide plate, making the material easier to adjust in actual working conditions. At the same time, when it is necessary to convey the material from top to bottom, the rotation of the two main shafts is changed, and the guide plate of the discharge port is flipped, so that the material is difficult to slip when conveyed from top to bottom in the initial state, which facilitates the reverse conveying of the material.

[0017] Optionally, the left spiral plate is equipped with first ball bearings on both sides of the edge in contact with the square material, and the right spiral plate is equipped with second ball bearings on both sides of the edge in contact with the square material.

[0018] By adopting the above technical solution, the arrangement of the first and second balls reduces the friction between the spiral plate and the square material, improves the stability of the conveying process, and extends the service life of the spiral plate.

[0019] Optionally, a plurality of first reinforcing plates are evenly fixed between the left spiral plate and the main shaft for fixing the left spiral plate along the spiral direction of the left spiral plate, and a plurality of second reinforcing plates are evenly fixed between the right spiral plate and the main shaft for fixing the right spiral plate along the spiral direction of the right spiral plate.

[0020] By adopting the above technical solutions, the structural strength and stability of the left and right spiral plates are increased, ensuring the smoothness and reliability of the double spiral vertical conveying equipment during operation and effectively extending the service life of the equipment.

[0021] Optionally, both the left and right spiral plates are integrally spliced ​​together from several spiral support plates, with the two ends of each spiral support plate abutting against the two sides of the square material.

[0022] By adopting the above technical solution, the two ends of the spiral support plate can better fit the two sides of the square material, improving the contact stability between the spiral plate and the material, making it less likely for the material to deviate or get stuck during vertical conveying, thereby improving the smoothness and efficiency of the conveying process.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. It enables linear conveying of rectangular material boxes, with a convenient structure and low manufacturing cost;

[0025] 2. High transportation stability, adaptable to linear conveying of rectangular material boxes of different lengths and sizes. Attached Figure Description

[0034] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0035] Example 1:

[0036] This application discloses a double-helix vertical conveying device for square materials.

[0037] Reference Figure 1 The present application provides a double spiral vertical conveying device for square materials, including a support 1, an inlet 2 at one end of the support 1 and an outlet 3 at the other end, and two main shafts 4 rotatably arranged in the support 1, one of the main shafts 4 having a left spiral plate 5 fixed on it and the other main shaft 4 having a right spiral plate 6 fixed on it.

[0038] Reference Figure 1 Specifically, the support frame 1 includes at least four uprights and several crossbeams. The uprights support the entire equipment, while the crossbeams increase the rigidity and stability of the equipment. Reinforcing ribs can be welded to the connection points between the crossbeams and uprights to further enhance stability.

[0039] Reference Figure 2 The left spiral plate 5 is formed by splicing at least three spiral support plates 24. Each spiral support plate 24 can be designed with a curve, and its specific shape can be adjusted according to the actual size of the material being conveyed. The spiral support plates 24 can be connected together by welding or other methods to enhance rigidity and stability. The specific material selection for the spiral support plates 24 needs to be determined based on the actual conditions of the material being conveyed.

[0040] Reference Figure 1 and Figure 2 The right spiral plate 6 is also formed by splicing at least three spiral support plates 24. The splicing method can be achieved by welding or machining, and the material can be cast iron, carbon steel, or stainless steel, depending on the conveying conditions. In this embodiment, during the conveying of the square cardboard box, the opposite edges of the cardboard box abut against the two ends of the corresponding spiral support plates 24, thereby limiting the square cardboard box itself by the spiral support plates 24 on both sides, thus ensuring that the cardboard box is difficult to slip or become unstable during transport.

[0041] Reference Figure 1 In this embodiment, to ensure stable conveying of square materials, a vertically arranged baffle 7 is fixedly installed inside the support 1, forming a vertical conveying zone between the left spiral plate 5, the right spiral plate 6, and the baffle 7. Simultaneously, to facilitate the placement of square materials into the corresponding area during material conveying, a feed inlet 2 is provided at one end of the support 1, and a discharge outlet 3 is provided at the other end. Guide plates 18 are provided at both the feed inlet 2 and the discharge outlet 3. The guide plates 18 can be fixedly installed or configured with an adjustable tilt angle.

[0042] Reference Figure 1 The support 1 is also equipped with a drive assembly 8 for driving the two main shafts 4 to rotate synchronously in opposite directions. When the square material is placed in the vertical conveying area, the drive assembly 8 drives the left spiral plate 5 and the right spiral plate 6 to rotate synchronously in opposite directions, thereby pushing the square material in a straight line along the length of the baffle 7.

[0043] Reference Figure 1 and Figure 3The drive assembly 8 includes a first gear 14, a second gear 15, a motor 16, and a drive gear 17. The first gear 14 is coaxially fixedly mounted on one of the main shafts 4, and the second gear 15 is coaxially fixedly mounted on the other main shaft 4. In this embodiment, the motor 16 is mounted at the bottom of the bracket 1. The drive gear 17 is coaxially fixedly mounted on the rotating shaft of the motor 16. The drive gear 17 meshes with the first gear 14, causing the first gear 14 and the second gear 15 to rotate synchronously in opposite directions.

[0044] Reference Figure 2 and Figure 3 In this embodiment, to ensure the stability of the entire equipment operation, several first reinforcing plates 22 are fixed between the left spiral plate 5 and the main shaft 4. The first reinforcing plates 22 are arranged along the spiral direction. At least two first reinforcing plates 22 are fixed between each spiral support plate 24 to ensure stability. The first reinforcing plates 22 are steel plates or structural steel, and different thicknesses are selected according to strength requirements. They are fixed to the main shaft 4 by welding to ensure the connection strength between the left spiral plate 5 and the main shaft 4.

[0045] Reference Figure 2 and Figure 3 Several second reinforcing plates 23 are fixed between the right spiral plate 6 and the main shaft 4, and the second reinforcing plates 23 are arranged along the spiral direction. At least two second reinforcing plates 23 are fixed between each spiral support plate 24. The second reinforcing plates 23 can be selected as steel plates or structural steel, and different thicknesses are selected according to different material strengths. They are fixed to the main shaft 4 by welding to ensure the stability of the overall structure.

[0046] Example 2:

[0047] Reference Figure 4 The difference between Embodiment 2 and Embodiment 1 is that, in order to achieve the conveying of square materials of different lengths and to ensure the stability of the conveying of square materials, a first mounting seat 9 is provided at one end of the support 1, and a second mounting seat 10 is provided at the other end. Both the first mounting seat 9 and the second mounting seat 10 are flat plates, and both the first mounting seat 9 and the second mounting seat 10 are slidably connected to the support 1.

[0048] Reference Figure 4 The two main shafts 4 are rotatably connected at one end to the first mounting base 9 and at the other end to the second mounting base 10. The connection method can be a bearing support structure, such as tapered roller bearings, to provide better radial and axial support.

[0049] Reference Figure 4 In this embodiment, in order to adjust the distance between the two spindles 4 and the stop bar 7, the drive assembly 8 is mounted on the second mounting base 10, and the bracket 1 is provided with an adjustment assembly 11 for adjusting the distance between the spindle 4 and the stop bar 7.

[0050] Reference Figure 4 The adjustment component 11 allows for manual or electric adjustment of the distance between the two main shafts 4 and the stop lever 7. Manual adjustment is possible, but electric adjustment is faster; manual adjustment offers higher precision. This component includes an adjusting screw 12 and a connecting block 13. The connecting block 13 is threadedly connected to the screw 12. Rotating the screw 12 causes the second mounting seat 10 to slide along the bracket 1. Simultaneously, the first mounting seat 9 slides along the second mounting seat 10, thus adjusting the distance between the main shafts 4 and the stop lever 7.

[0051] Reference Figure 5 In order to reduce wear on the square material itself during the conveying process, first ball bearings 20 are installed on both sides of the left spiral plate 5 where it contacts the square material, and second ball bearings 21 are installed on both sides of the right spiral plate 6 where it contacts the square material.

[0052] Reference Figure 4 and Figure 6 Since the entire equipment involves both upward and downward material conveying during the material transportation process, the guide plate 18 and the support 1 are configured for rotational adjustment. A spring plunger 19 is installed on the side wall of the guide plate 18. The ball head of the spring plunger 19 can abut against the side wall of the support 1, thereby realizing the angle adjustment of the guide plate 18. After adjustment, due to the abutting force of the ball head of the spring plunger 19, the guide plate 18 is difficult to rotate without a large external force, ensuring the stability of use.

[0053] The implementation principle of a double-helix vertical conveying device for square materials according to an embodiment of this application is as follows: This double-helix vertical conveying device achieves stable material conveying in the vertical direction through a design of double helical plates and a baffle 7. The synchronous counter-rotation of the left helical plate 5 and the right helical plate 6, combined with the baffle 7, ensures greater stability during material conveying, preventing jamming or slippage. Simultaneously, the spacing between the helical plates can be adjusted via the adjusting component 11 to meet the conveying needs of different types of square materials, improving the adaptability of the equipment. This solution solves the problems of material conveying efficiency and stability in the prior art, improving overall conveying efficiency.
