AI Technical Summary
In the traditional drying process, the grey cloth has a long drying time in the oven, about 55 minutes, resulting in slow drying speed and low production capacity.
A pre-drying device for drying drum is designed, including a rolling rolling cloth device and four heating rollers installed on a double-layer fixing rack. The moisture of the grey cloth is removed by the rolling rolling cloth device, and then the four heating rollers are heated to further remove the moisture, shortening the drying time of the oven.
Through this device, the drying time of the grey cloth is shortened to 40 minutes, which significantly improves the drying efficiency and production capacity.

Abstract
Description
Technical Field
[0001] The utility model relates to a drying barrel pre-drying device. Background Art
[0002] Before drying the grey cloth, the moisture inside needs to be squeezed out by a flattening mechanism before entering the drying oven. Using the traditional drying process, it takes about 55 minutes for the squeezed grey cloth to enter the drying oven. The drying structure is simple, the drying speed of the grey cloth is slow, and the production capacity is low. Therefore, a drying drum pre-drying device is proposed to address the above problems. Utility Model Content
[0003] The purpose of the utility model is to overcome the above-mentioned deficiencies in the prior art and to provide a drying barrel pre-drying device which has a reasonable design, a simple structure, and improves the drying speed and the production capacity.
[0004] The technical solution adopted by the utility model to solve the above-mentioned problem is: a drying drum pre-drying device, including a padding cloth pressing device, a double-layer fixed frame is arranged above the padding cloth pressing device, the double-layer fixed frame is equipped with a first upper heating roller and a second upper heating roller on the upper layer, and a first lower heating roller and a second lower heating roller on the lower layer, the first upper heating roller, the first lower heating roller, the second upper heating roller, and the second lower heating roller are arranged in sequence from left to right, the first upper heating roller and the second upper heating roller are arranged in a horizontal straight line, the first lower heating roller and the second lower heating roller are arranged in a horizontal straight line, the second upper heating roller is located above two adjacent lower heating rollers, and the first lower heating roller is located below two adjacent upper heating rollers; an oven is fixed on the right side of the lower layer of the double-layer fixed frame.
[0005] Preferably, the padding cloth pressing device comprises a fixed roller and a movable roller, the fixed roller and the movable roller are arranged in a horizontal straight line, and the movable roller is provided with an adjustment component. When the grey cloth needs to be installed, the operator can adjust the movable roller to leave the fixed roller through the adjustment component, and the grey cloth can be conveniently passed through by increasing the distance between the two.
[0006] The utility model provides an S-shaped or inverted S-shaped grey cloth between two adjacent heating rollers on the upper and lower layers, thereby increasing the contact area between the grey cloth and the heating rollers and better removing the residual moisture of the wet grey cloth.
[0007] The utility model can remove about 45% of the moisture from the wet grey cloth after being pressed by the cloth pressing device of the padder, and further remove 70% of the remaining moisture from the wet grey cloth after heating by four heating rollers, thereby shortening the drying time of the oven from the original 55 minutes to 40 minutes. Compared with the original process, the drying efficiency is greatly improved and the production capacity is increased.
[0008] Compared with the prior art, the utility model has the following advantages and effects: 1. Adding 4 heating rollers further removes the remaining moisture of the wet grey cloth, shortens the drying time of the oven, and improves the production capacity; 2. The grey cloth is in an S shape or an inverted S shape between two adjacent heating rollers on the upper and lower layers, which increases the contact area between the grey cloth and the heating rollers and better removes the residual moisture of the wet grey cloth; 3. The movable roller is provided with an adjustment component for easy installation and adjustment. BRIEF DESCRIPTION OF THE DRAWINGS
[0009] Figure 1 It is a schematic diagram of the structure of an embodiment of the utility model.
[0010] In the figure: a water tank 1, a padder cloth pressing device 2, a fixed roller 21, a movable roller 22, an adjustment component 21, a double-layer fixed frame 3, a first upper heating roller 4, a second upper heating roller 5, a first lower heating roller 6, a second lower heating roller 7, an oven 8, and a grey cloth 9. DETAILED DESCRIPTION
[0011] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.
[0012] See also Figure 1 The drum pre-drying device in this embodiment includes a padding cloth pressing device 2, a double-layer fixed frame 3 is arranged above the padding cloth pressing device 2, the double-layer fixed frame 3 is installed with a first upper heating roller 4 and a second upper heating roller 5 on the upper layer, and a first lower heating roller 6 and a second lower heating roller 7 on the lower layer, the first upper heating roller 4, the first lower heating roller 6, the second upper heating roller 5, and the second lower heating roller 7 are arranged in sequence from left to right, the first upper heating roller 4 and the second upper heating roller 5 are arranged in a horizontal straight line, the first lower heating roller 6 and the second lower heating roller 7 are arranged in a horizontal straight line, the second upper heating roller 5 is located above between two adjacent lower heating rollers, and the first lower heating roller 6 is located below between two adjacent upper heating rollers; an oven 8 is fixed on the right side of the lower layer of the double-layer fixed frame 3.
[0013] The cloth pressing device 2 of the present embodiment includes a fixed roller 21 and a movable roller 22, which are arranged in a horizontal straight line, and the movable roller 22 is provided with an adjustment component 23. When the grey cloth 9 needs to be installed, the operator can adjust the movable roller 22 to leave the fixed roller 21 through the adjustment component 23, and the grey cloth 9 can be conveniently passed through by increasing the distance between the two.
[0014] In this embodiment, the grey cloth 9 is in an inverted S shape between the first upper heating roller 4 and the first lower heating roller 6, the grey cloth 9 is in an S shape between the second upper heating roller 5 and the first lower heating roller 6, and the grey cloth 9 is in an inverted S shape between the first lower heating roller 5 and the second lower heating roller 7, thereby increasing the contact area between the grey cloth 9 and the heating rollers and better removing the residual moisture in the wet grey cloth.
[0015] After coming out of the water tank 1, the grey cloth 9 of this embodiment passes through the padding cloth pressing device 2, the first upper heating roller 4, the first lower heating roller 6, the second upper heating roller 5, the second lower heating roller 7 in sequence, and finally enters the drying oven 8. After the wet grey cloth 9 is pressed by the padding cloth pressing device 2, about 45% of the moisture can be removed, and 70% of the remaining moisture of the wet grey cloth can be further removed after heating by four heating rollers, thereby shortening the drying time of the drying oven 8, and the drying time of the drying oven 8 is shortened from the original 55 minutes to 40 minutes. Compared with the original process, the drying efficiency is greatly improved and the production capacity is increased.
[0016] In addition, it should be noted that all equivalent changes or simple changes made based on the structure, features and principles of the utility model patent are included in the protection scope of the utility model patent.
