As a preference, a hot air blower is arranged between adjacent upper drive rollers, and a hot air blower is arranged between adjacent lower drive rollers, the top height of the lower drive rollers is higher than the bottom height of the upper drive rollers, The heights of the inlet and outlet are the same.

As a preference, the lower drive roller is installed in the base through a support, the base is fixed on the bottom of the box body, the support is cylindrical, and a baffle is fixed at the bottom of the pedestal, the baffle The outer diameter is greater than the outer diameter of the support, and a compression spring is fixed at the bottom of the blocking piece. The outer diameter of the compression spring is not larger than the outer diameter of the blocking piece, and the base is sequentially provided with a supporting cavity and the spring cavity, the inner diameter of the support cavity matches the outer diameter of the support, the inner diameter of the spring cavity matches the outer diameter of the blocking plate, the spring cavity penetrates to the bottom of the base, and the compression spring The other end opposite to the baffle is fixed to the box body.

The utility model recycles the excess hot air in the box to the air inlet of the hot air blower. Since the original air of the hot air blower has high heat energy, the hot air blower can generate hot air with the same heat energy only with a lower power, thereby reducing the heat loss of the hot air blower. power, to achieve the purpose of energy saving.

detailed description

The utility model will be described in further detail below through specific embodiments in conjunction with the accompanying drawings.

As shown in Figure 1, a hot air circulation drying device for drying interlinings comprises a box body 1, the two ends of the box body 1 are provided with a material inlet 2 and a material outlet 3, and are installed in the box body The upper driving roller 4 at the top of the inner top and the lower driving roller 5 installed at the inner bottom of the box body 1, the upper driving roller 4 and the lower driving roller 5 are arranged at intervals, and the box body 1 is provided with a hot air blower 12 , the air outlet of the hot air blower 12 faces the inside of the box body 1, the air inlet is located outside the box body 1, and the box body 1 is provided with an air outlet 17, and the air outlet 17 is connected to the hot air blower 12 through the pipeline 14. The air inlets are connected, and a circulation fan 15 is connected in series on the pipeline 14 , and a supplementary air outlet 16 is provided on the pipeline 14 between the circulation fan 15 and the hot air blower 12 .

A hot air blower 12 is arranged between adjacent said upper drive rollers 4, and a hot air blower 12 is arranged between adjacent said lower drive rollers 5, and the top height of said lower drive rollers 5 is higher than that of the upper drive rollers 4. Bottom height, the heights of the feed inlet 2 and the discharge outlet 3 are the same.

The lower drive roller 5 is installed in the base 7 through the support 6, the base 7 is fixed on the bottom of the box 1, the support 6 is cylindrical, and the bottom of the support 6 is fixed with a baffle 8. The outer diameter of the blocking piece 8 is larger than the outer diameter of the support 6, and a compression spring 9 is fixed on the bottom of the blocking piece 8, and the outer diameter of the compression spring 9 is not larger than the outer diameter of the blocking piece 8. The base 7 is provided with a bearing cavity 10 and a spring cavity 11 sequentially from top to bottom. The diameter matches, the spring cavity 11 penetrates to the bottom of the base 7, and the other end of the compression spring 9 opposite to the blocking piece 8 is fixed to the box body 1 .

When the utility model is idle, the compression spring 9 is in a compressed state, and the blocking plate 8 is stuck on the top of the spring chamber 11. When in use, the lining cloth 13 enters the box body from the feeding port 2 and is placed on the upper transmission roller 4 and the lower transmission roller. Between the rollers 5, the hot air blower 12 blows hot air to dry the interlining 13, and then the interlining 13 is discharged from the discharge port 3. When the tension on the interlining 13 is relatively large, the lower driving roller 5 compresses the compression spring 9 downward, The baffle 8 also moves down accordingly, so that the tension on the interlining 13 is reduced, thereby avoiding damage to the interlining 13 and ensuring the quality of the interlining 13. When drying, the hot air blower 12 continues to generate hot air into the box 1 , the pressure in the box body 1 increases, and under the drive of the circulating fan 15, the hot air is discharged from the air outlet 17 and enters the air inlet of the hot air blower 12 as the original wind for heating by the hot air blower 12.
