Description

Technical Field

[0001] The invention belongs to the technical field of cloth drying, and in particular relates to a drying machine for knitted woolen sweater cloth. Background Art

[0002] Wool sweater originally refers to a knitted sweater made of wool, but in fact "wool sweater" has now become a synonym for a category of products, that is, it is used to refer to "knitted sweaters" or "wool knitwear". Wool knitwear refers to fabrics that are woven from wool, cashmere, rabbit hair and other animal hair fibers as the main raw materials, such as rabbit hair sweaters, snow blue sweaters, lamb sweaters, acrylic sweaters, etc. In the processing of wool sweater fabrics, the drying procedure of wool sweaters is essential.

[0003] The existing drying machines for knitted wool sweater fabrics have the following problems:

[0004] Existing drying machines for knitted wool sweater fabrics do not have the ability to lift the fabric that has sagged after being wetted, resulting in the flat fabric being pulled under the gravity of the concentrated water. When wool fibers are wet, the hydrogen bonds and intermolecular forces between fibers may change due to the presence of water, resulting in reduced strength, which in turn affects the overall quality of the fabric after drying. Therefore, the existing technology is difficult to meet the actual needs of drying knitted wool sweater fabrics. Summary of the invention

[0005] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a drying machine for knitted wool sweater fabrics, which can lift the fabric that is sunken after being wetted, avoid the pulling of the fabric by the accumulated water, and improve the overall drying quality of the fabric.

On the one hand, it can reduce the pressure inside the separated cavity. The negative pressure generated on the inside can prevent the cloth from being excessively bulged and pulled in the opposite direction. On the other hand, the suction force of the vacuum pump on the inside of the drying box can be prevented from gradually decreasing from top to bottom, causing the cloth in the lower layer of the drying box to remain in a sunken state.

Subsequently, the vacuum pump draws the air inside the drying box through the vacuum pipe, and the air inside the drying box flows into the collecting tube through the vacuum pipe, and is discharged from the collecting tube under the action of the exhaust end of the vacuum pump. The hot air generated inside the insulation box flows into the drying box through the one-way air inlet valve to dry the material inside the drying box. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] A controller 35 is disposed on the side wall of the drying box 1 .

[0038] The controller 35 is electrically connected to the air pump 7 , the electric valve 11 , the pressure sensor 12 and the high-frequency coil 18 , respectively.

[0039] The model of the controller 35 is SYC89C52RC-401.

[0040] The model of the pressure sensor 12 is CYYZ11A.

[0041] When in use, in embodiment 1, the bolt 24 is manually rotated, the bolt 24 is unscrewed from the inside of the threaded hole 22, the sealing door 23 is taken down from the side wall of the drying box 1, the opening of the drying box 1 is opened, and the cloth pressing frame plate 30 placed in the cloth loading box 26 is pulled out. First, one cloth pressing frame plate 30 is placed on the ground, and the wet knitted wool sweater fabric is laid flat on the cloth pressing frame plate 30 in turn. The superimposed height of the knitted wool sweater fabric is less than the height of the cloth loading box 26, and the other cloth pressing frame plate 30 is pressed on the knitted wool sweater fabric. The operator uses the deformation of the clamping spring 29 to place the knitted wool sweater fabric to be dried between the cloth loading boxes 26 inside the drying box 1 through the cloth pressing frame plate 30. The guide rod 27 is against the cloth pressing frame plate 30 through the elasticity of the clamping spring 29. The guide rod 27 fixes the fabric entering the drying box 1, and the knitted wool sweater fabric is placed horizontally inside the drying box 1;

[0042] In the initial state, the push-close spring 32 is extended, and the cloth pressing frame plate 30 that slides into the cloth loading box 26 is fitted with the push-close plate 33. The operator lifts the sealing door 23 and fits it against the side wall of the drying box 1, and rotates the bolt 24. The bolt 24 is screwed into the threaded hole 22. The sealing door 23 seals the drying box 1. The cloth pressing frame plate 30 is squeezed between the push-close plate 33 and the sealing door 23 through the sealing gasket 34. Under the action of the cloth pressing frame plate 30 and the cloth, the interior of the drying box 1 is divided into a plurality of sealed cavities.

[0043] The moisture inside the fabric will gather in the middle part under the action of gravity, causing the weight of the middle part of the fabric to increase, and exert a downward pulling force on the fabric, which will affect the quality of the fabric after drying. The higher the humidity of the fabric, the greater the pulling force from the water on the fabric, and the worse the air circulation rate of the fabric.

[0044] The controller 35 controls the high-frequency coil 18 to start, and the high-frequency coil 18 is energized to heat the metal rod 19, and the metal rod 19 heats the air inside the heat preservation box 15. Then, the controller 35 controls the vacuum pump 7 to start, and the vacuum pump 7 extracts the air inside the drying box 1 through the vacuum pipe 8. The air inside the drying box 1 flows into the collecting tube 6 through the vacuum pipe 8, and is discharged from the collecting tube 6 under the action of the exhaust end of the vacuum pump 7. At this time, the inside of the drying box 1 is in a negative pressure state, and the outside air enters the heat preservation box 15 after being filtered by the filter 16. The hot air generated inside the heat preservation box 15 flows into the inside of the drying box 1 through the one-way air inlet valve 17. The hot air penetrates the cloth from bottom to top under the suction force of the vacuum pipe 8, and the moisture inside the cloth is taken away by the hot air flow, so as to dry the cloth inside the drying box 1.

[0045] When the knitted wool sweater fabric is very wet, the resistance to the flow of hot air inside the drying box 1 is relatively large, the exhaust volume of the vacuum pump 7 is greater than the flow volume of gas through the fabric, and the adsorption pressure on the layer of fabric with a higher moisture content inside the drying box 1 gradually increases, causing the fabric to passively tend to be horizontal, thereby preventing moisture accumulation and exerting a downward pulling force on the fabric. As the time for hot air inside the insulation box 15 to circulate through the fabric increases, the moisture in the fabric gradually decreases, allowing the fabric to actively maintain a relatively horizontal state, thereby completing the drying operation of the fabric.

[0046] Embodiment 2: This embodiment is based on the above embodiment. Since the humidity of each layer of fabric is different, the air permeability of each layer of fabric is different. When the moisture content of the fabric on the upper part of the drying box 1 is high, in order to prevent the upper fabric from being excessively reversely adsorbed, the detection end of the pressure sensor 12 above the controller 35 passes through the auxiliary flow seat 10 and is arranged inside the partition cavity on the upper part of the drying box 1. The detection end of the pressure sensor 12 below the controller 35 passes through the auxiliary flow seat 10 and is arranged inside the partition cavity in the middle part of the drying box 1. The threshold value of the pressure sensor 12 is pre-set. The controller 35 controls the pressure sensor 12 above it to start. The pressure sensor 1 2 monitors the pressure of the compartment cavity at the upper part of the drying box 1. When the pressure of the compartment cavity at the upper part of the drying box 1 separated by the cloth reaches the threshold value of the pressure sensor 12, the controller 35 controls the electric valves 11 at the middle and bottom of the drying box 1 to open, and the drying box 1 is connected to the auxiliary flow pipe 13. The auxiliary flow pipe 13 shunts the suction force of the exhaust pipe 8, thereby reducing the reverse pulling force on the cloth at the upper part of the drying box 1 and reducing the number of layers of the hot air flowing through the cloth. The hot air passes through three groups of cloth and changes to the hot air passing through one or two groups of cloth. Under the condition of keeping the cloth with a higher water content in a horizontal state, the loss of water in the cloth is accelerated.

[0047] When the electric valve 11 is blocked and cut off, when the moisture content of the cloth in the middle of the drying box 1 is high, under the adsorption of the exhaust pipe 8, the pressure sensor 12 monitors that the pressure inside the corresponding partition cavity gradually decreases, and the controller 35 controls the electric valve 11 at the bottom of the drying box 1 to be turned on, and the hot air from the heat preservation box 15 passes through the cloth at the bottom of the drying box 1 and enters the electric valve 11 connected to the partition cavity. When the hot air flows through the bottom wall of the cloth in the middle of the drying box 1, the moisture inside the cloth in the middle of the drying box 1 can be lost, thereby increasing the ventilation rate of the cloth in the middle of the drying box 1. After the pressure sensor 12 in the middle of the drying box 1 monitors that the pressure inside the corresponding partition cavity rises, the ventilation rate of the cloth in the middle of the drying box 1 increases, and the controller 35 controls the electric valve 11 to be closed, and the exhaust pipe 8 discharges the gas inside the drying box 1 to allow the hot air inside the heat preservation box 15 to penetrate multiple layers of cloth.

[0048] When the electric valve 11 is blocked and cut off, when the moisture content of the cloth at the bottom of the drying box 1 is relatively high, the suction force of the exhaust pipe 8 penetrates the upper and middle parts of the drying box 1 to absorb the cloth layer at the bottom of the drying box 1, and the cloth layer at the bottom of the drying box 1 changes from a concave state to a relatively horizontal state. The bottom hot copper block 36 directly conducts the heat inside the insulation box 15 into the cloth at the bottom of the drying box 1, accelerates the evaporation of moisture in the cloth at the bottom of the drying box 1, ensures the air permeability of the cloth at the bottom of the drying box 1, and ensures that the upper layer of cloth can be penetrated by hot air. When the moisture inside the cloth layer at the bottom of the drying box 1 gradually evaporates, the suction force of the exhaust pipe 8 on the bottom of the drying box 1 decreases, and the hot air inside the insulation box 15 penetrates the inside of the drying box 1 through the one-way air inlet valve 17, completing the drying operation of the cloth; the above operation can be repeated when it is used next time.

[0049] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0050] The above is a description of the present solution and its implementation methods, which is not restrictive. The drawings show only one implementation method of the present solution, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creative design without departing from the creative purpose of the present solution, they should all fall within the protection scope of the present solution.
