Description

Technical Field

[0001] The utility model relates to the technical field of air boxes for hot air dryers, in particular to a stamped partition bar combination piece of an air box for a hot air dryer. Background Art

[0002] For example, a wind box for a hot air dryer disclosed in Chinese application number CN200720036388.6 is provided with a long slot-shaped air outlet. The long slot-shaped air outlets are arranged end to end without overlapping each other, which can ensure that the hot air blown out by the wind box has no blind spots on the fabric, and further ensure that the wind box sprays out hot air evenly and stably, avoiding defects such as color difference and streaking on the dried fabric.

[0003] like Figure 4 In the conventional partition bar combination shown in the figure, the long groove-shaped air outlet is generally formed by welding a number of equidistantly arranged U-shaped plates and an L-shaped plate in the middle. The disadvantage is that the welding positioning accuracy of the U-shaped plate and the L-shaped plate is low, and the U-shaped plate is formed by folding the straight plate. The heights of the two sides of the U-shaped plate cannot be guaranteed to be the same, which easily leads to uneven air output of the formed air box. Utility Model Content

[0004] The utility model aims to solve the shortcomings of the prior art and provide a spacer bar combination part of an air box for a hot air drying machine which is formed by die stamping and has high production efficiency.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a stamped and formed partition bar assembly of a wind box for a hot air dryer, comprising a wind box, an inner cavity of the wind box is inclined and provided with a wind shield plate which divides the inner cavity into two, the left and right ends of the wind box are air inlets, the upper and lower ends of the wind box are air outlets, and a partition bar assembly is provided at the air outlet, the partition bar assembly comprises an L-shaped plate, an upper stamped forming plate, a lower stamped forming plate and a connecting plate, the upper stamped forming plate and the lower stamped forming plate are both formed by die stamping to form a plurality of partition bars with the same height and the same spacing, the upper stamped forming plate and the lower stamped forming plate are respectively fixed to the upper and lower sides of the L-shaped plate, and the partition bars belonging to the upper stamped forming plate and the partition bars belonging to the lower stamped forming plate are staggered.

[0006] Preferably, the connecting plate is parallel to the L-shaped plate, and the left and right ends of the connecting plate are respectively fixed to the top edges of adjacent spacer strips.

[0007] Preferably, all the spacer strips formed by die stamping are perpendicular to the stamping plates to which they belong.

[0008] Compared with the prior art, the utility model has the following advantages: all the stamped plates are formed by die stamping to form spacers with uniform height and angle, so that the air volume of the spacers corresponding to the air outlets is uniform. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The present invention is further explained below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that these implementation methods are only used to illustrate the present invention and are not used to limit the scope of the present invention. After reading the present invention, various equivalent forms of modifications to the present invention by those skilled in the art all fall within the scope defined by the claims attached to this application.

[0015] like Figures 1 to 3 The stamped hot air dryer air box partition bar assembly shown comprises an air box 1, the inner cavity of the air box 1 is inclinedly provided with a wind shield 2 that divides the inner cavity into two, the left and right ends of the air box 1 are air inlets, the upper and lower ends of the air box 1 are air outlets, and the air outlets are provided with a partition bar assembly 3;

[0016] The spacer strip combination comprises an L-shaped plate 4, an upper stamping forming plate 6, a lower stamping forming plate 7 and a connecting plate 8. The upper stamping forming plate 6 and the lower stamping forming plate 7 are both formed by die stamping to form a plurality of spacer strips 5 of the same height and the same spacing. The upper stamping forming plate 6 and the lower stamping forming plate 7 are respectively fixed to the upper and lower sides of the L-shaped plate 4. The spacer strips 5 belonging to the upper stamping forming plate 6 and the spacer strips 5 belonging to the lower stamping forming plate 7 are staggered, and all the spacer strips 5 formed by die stamping are perpendicular to the stamping forming plates to which they belong.

[0017] The connecting plate 8 is parallel to the L-shaped plate 4, and the left and right ends of the connecting plate 8 are respectively welded to the top edges of the adjacent partition strips 5. The connecting plate 8 is fixed to the shell of the air box 1 by bolts as a connecting component between the air box 1 and the partition strip combination 3.

[0018] The partition bar assembly in this embodiment is formed by combining and welding an L-shaped plate, an upper stamping plate and a lower stamping plate. The L-shaped plate, the upper stamping plate and the lower stamping plate can all be formed by mold stamping, thereby greatly improving production efficiency. Compared with conventional practices, a large amount of welding work is reduced, and the control over the height and angle of the partition bar is improved, so that the air output of the air box is more uniform.

[0019] The above description shows and describes the preferred embodiments of the utility model. As mentioned above, it should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the utility model concept described herein through the above teachings or the technology or knowledge of the relevant field. The changes and modifications made by those skilled in the art do not depart from the spirit and scope of the utility model, and should be within the scope of protection of the claims attached to the utility model.
