Description

Technical Field

[0001] The utility model relates to the technical field of spiral turning machines, in particular to a spiral turning machine body frame and a spiral turning machine. Background Art

[0002] In current express delivery sorting equipment, in order to meet the needs of the height difference and turning connection of the conveyor line on the site, as well as the connection from low floors to high floors, a spiral belt turning machine (referred to as "turning machine") needs to be installed at a specific location. Since the belt support plate of the turning machine is a sheet metal with a spiral surface, the existing technology usually adopts the method of tapping and spot welding of tooling, or uses a stamping die to shape a whole flat plate into a spiral surface. However, due to the large area of ​​the belt support plate, the sheet metal after tapping and plasticization has a large overall stress after welding, which is prone to desoldering due to warping, and the equipment investment required for forming by stamping die is high.

[0003] It can be seen that the existing technology still needs to be improved and enhanced. Utility Model Content

[0004] In view of the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide a spiral turning machine body frame and a spiral turning machine, aiming to solve the defect in the prior art that the belt support plate of the spiral turning machine at the spiral turning part is easily desoldered.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A spiral turning machine fuselage frame includes a belt support plate and an inner arc plate and an outer arc plate arranged on both sides of the belt support plate, wherein the belt support plate is composed of a plurality of strip-shaped strip panels; a plurality of positioning ribs are also provided below the plurality of strip panels, and the positioning ribs are used to position and configure the strip panels when welding the strip panels.

[0007] In the spiral turning machine fuselage frame, a first protrusion is provided on the top edge where the positioning rib contacts the strip panel, and a first slot for inserting the first protrusion is provided at a position of the strip panel corresponding to the first protrusion.

[0008] In the spiral turning machine fuselage frame, second protrusions are provided at both ends of the positioning rib, and multiple second slots for plugging the second protrusions are provided on the inner arc plate and the outer arc plate, and the multiple second slots are linearly spirally distributed on the inner arc plate and the outer arc plate.

[0009] In the spiral turning machine fuselage frame, a plurality of reinforcing ribs are provided between the inner arc plate and the outer arc plate.

[0011] Beneficial effects:

[0012] The utility model provides a spiral turning machine frame. By providing a belt support plate composed of multiple strip panels, the stress generated when the flat panels form a spiral curve can be dispersed, preventing desoldering caused by stress concentration. Positioning ribs are provided to facilitate the configuration of the strip panels so that the belt support plate with a spiral curve can be formed through welding. A spiral turning machine using this frame will not experience desoldering on the belt support plate at the spiral curve, reducing the frequency and difficulty of maintenance.

[0017] The present invention provides a spiral turning machine body frame and a spiral turning machine. To make the purpose, technical solution and effect of the present invention clearer and more specific, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific examples described here are only used to explain the present invention and are not intended to limit the present invention.

[0018] See also Figure 1-3The preferred embodiment of the present invention provides a spiral bending machine fuselage frame, comprising a spirally curved belt support plate 1 and inner and outer curved plates 2 and 3 disposed on either side of the belt support plate 1. The inner and outer curved plates 2 and 3 have the same curvature and are spirally parallel. Because the belt support plate 1 is spirally curved, i.e., it has both a bend and a height difference, forming it from a single, flat sheet metal would result in significant stress, which could easily lead to desoldering due to stress concentration at a specific point. In this regard, the present embodiment welds and combines a plurality of small strip panels 4 to form a belt pallet 1 with a spiral curved surface shape, that is, it is equivalent to dividing the belt pallet 1 into a finite number of small strip panels 4 (the specific number of strip panels 4 is determined according to the width of the belt pallet 1, the angle of the spiral turn and the height difference), and then welding each small strip panel 4 to form a spiral curved surface, which are then combined to form a belt pallet 1 with a spiral curved surface shape. Since the width of each strip panel 4 is smaller than the width of the belt pallet 1, the stress generated when the strip panel 4 forms a spiral curved surface is also smaller, which is equivalent to dispersing the stress of the belt pallet 1 as a whole, thereby avoiding the phenomenon of desoldering caused by the deformation stress being concentrated at one point, thereby achieving the goal of reducing the occurrence of desoldering while obtaining a good spiral curved surface configuration.

[0019] However, when welding the plurality of strip panels 4, it is necessary to make each strip panel 4 form a spiral surface, and to ensure that the spiral surfaces formed by two adjacent strip panels 4 are continuous. Therefore, compared with a single piece of sheet metal configuration, it is more difficult. Figure 2 、 Figure 3 As shown, multiple positioning ribs 5 are provided below the plurality of strip panels 4. The extension direction of the positioning ribs 5 intersects that of the strip panels 4, forming a fan-shaped framework that radiates between the inner arc plate 2 and the outer arc plate 3. Multiple first protrusions 6 are provided on the top edges where the positioning ribs 5 contact the strip panels 4. First slots 7 for receiving the first protrusions 6 are provided in the strip panels 4 at positions corresponding to the first protrusions 6. Therefore, during welding, the first protrusions 6 can be used for positioning, ensuring that all strip panels 4 connected to the same positioning rib 5 are on the same curved surface on that positioning rib 5. The combined action of all the reinforcing ribs 10 allows the strip panels 4 to form a continuous spiral curved surface after welding. Furthermore, the positioning ribs 5 provide support for the strip panels 4 both before and after welding.

[0020] In order to facilitate the spiral surface configuration, the plurality of positioning ribs 5 can play a better positioning and forming role. In a preferred embodiment, as shown in FIG. Figure 2 、 Figure 3As shown, both ends of the positioning rib 5 are provided with a second protrusion 8, and the inner arc plate 2 and the outer arc plate 3 are provided with a plurality of second slots 9 for inserting the second protrusions 8. The plurality of second slots 9 are linearly spirally distributed on the inner arc plate 2 and the outer arc plate 3. When all the positioning ribs 5 are inserted into the second slots 9 on the inner arc plate 2 and the outer arc plate 3 one by one, the upper surfaces of the plurality of positioning ribs 5 can form a spiral curved surface, thereby playing a role in positioning and configuring the strip panel 4.

[0021] In addition, in order to strengthen the strength of the fuselage frame, such as Figure 1 、 Figure 2 As shown, a plurality of reinforcing ribs 10 are provided between the inner arc plate 2 and the outer arc plate 3 .

[0022] When welding the spiral turning machine fuselage frame, the inner arc plate 2 and the outer arc plate 3 are first positioned and fixed in the welding tooling, and then the reinforcing ribs 10 and the positioning ribs 5 are assembled and welded in sequence, and then the strip panel 4 is assembled and welded. After welding is completed, it is polished and formed to obtain a fuselage frame with a spiral curved surface configuration.

[0023] The second aspect of the present invention also provides a spiral turning machine, which includes the spiral turning machine body frame as described above. Therefore, during use, the belt support plate 1 at the spiral turning position will not become desoldered, which can reduce the frequency and difficulty of maintenance and has a longer service life.

[0024] To sum up, the spiral turning machine fuselage frame described in this embodiment can disperse the stress generated by the flat plate when forming a spiral surface by setting a belt support plate 1 composed of multiple strip panels 4, thereby avoiding the desoldering phenomenon caused by stress concentration; by setting positioning ribs 5, it is convenient to configure the strip panels 4 so as to form a spiral curved belt support plate 1 through welding.
