Description

Technical Field

[0001] The present application relates to the technical field of can conveying equipment, and in particular to an air conveying line adjustment structure. Background Art

[0002] During the production process, cans are generally transported through air conveying lines.

[0003] The can air conveying line is generally a shell structure with an internal cavity for high-speed air to pass through. Air holes for air conveying are opened on the can conveying side. The top is abutted against the top of the can through a cover plate to improve the stability of the can movement and reduce the probability of the can tipping over.

[0004] During the installation of the air conveying line, the surface may be uneven because the conveying surface of some air conveying lines is large and the material is thin. Generally, internal supports are provided in the shell structure of the air conveying line to support the thin plate on the surface of the air conveying line, thereby improving the flatness. However, even if support plates of the same specifications are used for internal support, the problem of uneven conveying surface of the air conveying line will still occur. In addition, during the use of the air conveying line, if the height of the cans conveyed by the air conveying line is changed, the installation height of the top cover plate needs to be adjusted. The existing cover plate is generally fixed on the support column. The efficiency of cover plate adjustment is low and the height of each support column after adjustment is difficult to align, which leads to low adjustability of the can air conveying line and low efficiency of cover plate height adjustment.

DETAILED DESCRIPTION

[0039] The following is combined with Figure 1-3This application is described in further detail.

[0040] The embodiment of the present application discloses an air delivery line adjustment structure.

[0041] refer to Figure 1 and Figure 2 The air delivery line adjustment structure includes a frame 1, a bottom bar frame 2, a top bar frame 3, a support plate 4, a main frame 6, a sliding frame 7 and a cover plate 72.

[0042] The frame 1 is provided with an opening, and the bottom of the frame 1 is connected to the air outlet of the fan. An air duct plate 11 is installed on the top of the frame 1, and the air duct plate 11 has multiple air holes. The bottom bar frame 2 and the top bar frame 3 are both C-shaped steel. There are multiple bottom bar frames 2, which are fixed on the inner bottom wall of the frame 1 at equal intervals, perpendicular to the moving direction of the cans on the frame 1, and the opening is set upward. The top bar frame 3 is located directly above the bottom bar frame 2, and the opening is set downward. An adjustment component 5 is provided between the top bar frame 3 and the bottom bar frame 2 to support the top bar frame 3 and adjust the distance between the top bar frame 3 and the bottom bar frame 2. There are multiple support plates 4, which abut on the top bar frame 3 and support the bottom of the air duct plate 11. The support plates 4 are arranged horizontally and perpendicular to the top bar frame 3, and are arranged at equal intervals between the support plates 4. The cross-section of the support plate 4 is "Z"-shaped, with the middle part arranged vertically and the top and bottom extended parts arranged horizontally. Multiple main frames 6 are vertically mounted on the two side walls of the frame body 1. Sliding frames 7 are vertically mounted and slidably connected within the main frames 6. A height adjustment assembly 8 is located between the main frames 6 and the sliding frames 7 to adjust the position of the sliding frames 7. A cover plate 72 abuts the top of the sliding frames 7, positioned above the air duct plate 11. Side panels 721 are fixed to the two side walls of the cover plate 72, with the sliding frames 7 positioned between the two side panels 721. A closable access door 12 is provided at the bottom of the frame body 1, between two adjacent bottom bar frames 2.

[0043] The multiple support plates 4 are supported by multiple evenly distributed top bar frames 3, thereby evenly supporting the air duct plate 11, and the height of the top bar frames 3 is adjusted by the adjustment component 5 to achieve the adjustability of the support plates 4. The support plates 4 effectively improve their own structural strength through their own cross-sectional structure, and increase the contact area with the air duct plate 11. The position setting of the support plates 4 and the top bar frames 3 can effectively reduce the shielding of the air holes on the air duct plate 11, thereby improving the uniformity of the air outlet of the air holes on the air duct plate 11. The cover plate 72 is buckled on the sliding frame 7 by abutting. When the sliding frame 7 is adjusted in height by the height adjustment component 8, the cover plate 72 can also be stably located on the sliding frame 7, and the stability on the sliding frame 7 is improved by the side panels 721, which not only realizes the height adjustment of the cover plate 72, but also improves the efficiency of the height adjustment of the cover plate 72.

[0044] refer to Figure 2The adjustment assembly 5 includes an adjusting screw 51, a fixing nut 55, a bottom gasket 53, a top gasket 54 and a fixing nut 55. There are multiple adjusting screws 51, which are inserted into the bottom bar frame 2, arranged vertically, and the top passes through the top bar frame 3. The bottom gasket 53 is sleeved on the bottom of the adjusting screw 51, and the adjusting nut 52 is threadedly connected to the adjusting screw 51. The adjusting nut 52 abuts against the top of the bottom gasket 53, so that the bottom gasket 53 abuts against the upper surface of the bottom bar hole. There are two top gaskets 54, which are sleeved on the adjusting screw 51 and are located at the top and bottom of the top bar frame 3. There are two fixing nuts 55, which are threadedly connected to the adjusting screw 51, pressing the two top gaskets 54 against the top bar frame 3. When the position of the top bar frame 3 needs to be adjusted, it is only necessary to rotate the adjusting nut 52 to adjust the position of the adjusting nut 52 on the adjusting screw 51.

[0045] refer to Figure 3 The height adjustment assembly 8 includes an upper lifting plate 81 and an upper lifting rod 82. A vertically arranged sliding bar hole 62 is provided on the side wall at the bottom of the main frame 6. The upper lifting plate 81 is rotatably connected to the side wall of the main frame 6 and is located below the sliding bar hole 62, with the rotation axis arranged horizontally. There are two upper lifting rods 82, which are rotatably connected on both sides of the middle part of the upper lifting plate 81. The other end of the upper lifting rod 82 passes through the sliding bar hole 62 and is rotatably connected to the side wall of the sliding frame 7, thereby driving the sliding frame 7 to slide up and down through the rotation of the upper lifting plate 81. The side wall of the main frame 6 has multiple groups of positioning holes 61 above the sliding bar hole 62. In this embodiment, there are two groups of positioning holes 61. Each group contains two positioning holes 61, which are arranged vertically, and the positioning holes 61 between each group are staggered. A connecting hole 71 is provided on the side wall of the sliding frame 7. The connecting hole 71 is a bar hole that can be directly opposite to the positioning holes 61 in the two groups. Inserted into positioning hole 61 is an insertion rod 9, which can simultaneously pass through both opposing positioning holes 61 and connecting hole 71. One end of the insertion rod 9 is rotatably connected to a stabilizing frame 91, the other end of which is sleeved onto the other end of the insertion rod 9. Stabilizing frame 91 is made of an elastically deformable material, in this embodiment, plastic.

[0046] When the height of the sliding frame 7 needs to be adjusted, the insertion rod 9 is pulled out and the upper lifting plate 81 is pushed. The rotation of the upper lifting plate 81 drives the sliding frame 7 to slide up and down. When the connecting hole 71 is aligned with the corresponding positioning hole 61, the insertion rod 9 is passed through the positioning hole 61 and the connecting hole 71. Then, the other end of the stabilizing frame 91 is sleeved on the end of the insertion rod 9 to fix the position of the insertion rod 9, thereby completing the position adjustment of the sliding frame 7 and effectively improving the efficiency of the position adjustment of the sliding frame 7. The grouping of the positioning holes 61 can stagger the positions of the positioning holes 61, thereby increasing the load pressure that the openings of the positioning holes 61 can withstand. The bar hole setting of the connecting hole 71 can face the two groups of positioning holes 61. The setting of the stabilizing frame 91 can effectively reduce the probability of the other end of the insertion rod 9 falling off from the positioning hole 61 and improve the stability of the position of the insertion rod 9.

[0047] The implementation principle of the air delivery line adjustment structure of the embodiment of the present application is as follows: the top bar frame 3 is supported by the adjusting screw 51, and the top bar frame 3 supports multiple support plates 4, and the support plates 4 support the air duct plate 11 to improve the flatness of the air duct plate 11. The position of the top bar frame 3 can be adjusted by adjusting the position of the adjusting nut 52 on the adjusting screw 51, thereby achieving the adjustability of the flatness of the air duct plate 11. The cover plate 72 is placed on the top of the sliding frame 7 in abutment manner. When the height of the cover plate 72 needs to be adjusted, the sliding frame 7 is driven to move up and down by rotating the lifting plate 81, and the height of the sliding frame 7 is fixed by inserting the insertion rod 9 into the corresponding positioning hole 61 and the connecting hole 71, thereby quickly and stably achieving the position adjustment of the sliding frame 7. Therefore, the height adjustment of the cover plate 72 can be achieved without removing the cover plate 72.

[0048] The embodiments of this specific implementation method are all preferred embodiments of the present application and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
