[0012] Beneficial effects

[0013] This invention provides a double-sided drying device for knitted fabric production. Compared with the prior art, it has the following advantages:

[0014] 1. This double-sided drying equipment for knitted fabric production uses an adjustable component to move knitted fabric of the appropriate size between the first and second drying rollers. A cylinder assembly adjusts the height of the moving frame and the first drying roller, causing the first drying roller to press and squeeze the knitted fabric onto the second drying roller, thus heating both rollers. A motor, through multiple sets of third bevel gear assemblies, a cross shaft, a sleeve, and the first and second bevel gear assemblies working together, drives the multiple sets of first and second drying rollers to rotate in opposite directions. This achieves the squeezing, conveying, and drying of the knitted fabric, enabling double-sided drying. This facilitates the storage of knitted fabric to be dried, fully squeezes and dries the fabric, improves drying efficiency, and allows for timely removal of the dried fabric, reducing damage caused by overheating.

[0015] 2. This double-sided drying equipment for knitted fabric production incorporates an extraction unit within the device. During the drying process, an air pump extracts air from the periphery of the feed trough and discharge trough of the casing through the casing, branch pipe, and four sets of extraction shells. A liquid pump draws in external coolant, injects it into the cooling pipe through the drain pipe, and returns it to the coolant storage end through the return pipe. When the high-temperature steam in the extracted gas passes through the casing, the coolant flowing through the cooling pipe absorbs heat from the water vapor in the gas through heat exchange, causing the steam to liquefy. This configuration effectively handles the steam generated during the drying of knitted fabric, avoiding the safety hazards caused by direct steam discharge. Attached Figure Description

[0024] The air extraction component 3 is installed on the top of the housing 1 for drying steam extraction. The air extraction component 3 includes an air pump 31 installed on the top of the housing 1. A housing 32 is installed on the air pump 31 on the extraction side. A cooling component 33 for steam cooling is installed inside the housing 32. A branch pipe 35 is provided on the left side of the housing 32.

[0025] Adjustment component 2 also includes multiple sets of third bevel gear assemblies 27 installed at the output end of motor 25 for driving transmission component 26. Transmission component 26 includes a cross shaft 261 connected to the bottom of the third bevel gear assembly 27. A first bevel gear assembly 263 for driving the first drying roller 23 is installed on the front side of the moving frame 22. A sleeve 262 rotatably connected to the upper side of the first bevel gear assembly 263 is connected to the upper side of the moving frame 22. A cross groove slidably connected to the cross shaft 261 is provided on the inner side of the sleeve 262. A second bevel gear assembly 264 for driving the second drying roller 24 is installed at the bottom of the cross shaft 261.

[0026] The output end of motor 25 is coaxially and fixedly connected to the third driving bevel gear in multiple sets of third bevel gear assemblies 27.

[0027] The knitted fabric of the appropriate size is moved between the first drying roller 23 and the second drying roller 24. The height of the moving frame 22 and the first drying roller 23 is adjusted by the cylinder assembly 21, so that the first drying roller 23 presses the knitted fabric on the upper side of the second drying roller 24 and squeezes it. The moving frame 22 drives the sleeve 262 to slide along the cross shaft 261, so that the first drying roller 23 and the second drying roller 24 are heated. The motor 25, through the cooperation of multiple sets of third bevel gear assemblies 27, cross shaft 261, sleeve 262, first bevel gear assembly 263, and second bevel gear assembly 264, drives multiple sets of first drying rollers 23 and second drying rollers 24 to rotate in opposite directions, so as to squeeze, convey and dry the knitted fabric, and achieve double-sided drying of the knitted fabric.

[0028] The main difference between the second implementation method and the first implementation method is that:

[0029] Cooling component 33 includes a liquid pump 331 mounted on the top of housing 1. The liquid pump 331 has a liquid suction pipe at its suction end and a liquid discharge pipe 332 at its discharge end. A cooling pipe 333, fixedly connected to and communicating with the liquid discharge pipe 332, is installed inside housing 32. The cooling pipe 333 is spirally arranged inside housing 32. A return pipe 334, fixedly connected to housing 32, is installed on the side of cooling pipe 333 away from the liquid discharge pipe 332. During the drying process, air pump 31... The gas is extracted from the periphery of the feed trough and discharge trough of the housing 1 through the housing 32, the branch pipe 35, and the four sets of extraction shells 36 respectively. The liquid pump 331 draws in the external coolant and injects it into the cooling pipe 333 through the drain pipe 332 and returns it to the coolant storage end through the return pipe 334. When the high temperature steam in the extracted gas passes through the housing 32, the coolant flowing through the cooling pipe 333 absorbs heat from the water vapor in the gas through heat exchange, and the steam is liquefied.

[0030] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.

[0031] In use, the user feeds a knitted fabric of the appropriate size into the feed chute on the left side of the housing 1 between the first drying roller 23 and the second drying roller 24. The user adjusts the height of the moving frame 22 and the first drying roller 23 by means of the cylinder assembly 21, so that the first drying roller 23 presses the knitted fabric on the upper side of the second drying roller 24 and squeezes it. During this process, the moving frame 22 drives the sleeve 262 to slide along the cross shaft 261, which supplies power to the first drying roller 23 and the second drying roller 24. The first drying roller 23 and the second drying roller 24 heat up and start the motor 25. The motor 25 drives the multiple sets of cross shafts 261 to rotate through multiple sets of third bevel gear assemblies 27. The rotation of the cross shaft 261, sleeve 262, first bevel gear assembly 263, and second bevel gear assembly 264 cooperates with each other to drive the multiple sets of first drying rollers 23 and second drying rollers 24 to rotate in opposite directions.

[0032] The first drying roller 23 and the second drying roller 24, which rotate in opposite directions, squeeze, convey, and dry the knitted fabric, achieving double-sided drying of the knitted fabric. Finally, the dried knitted fabric is discharged from the discharge trough on the right side of the housing 1. During the drying process, the air pump 31 and the liquid pump 331 are started. The air pump 31 extracts air from the periphery of the feed trough and discharge trough of the housing 1 through the housing 32, the branch pipe 35, and the four sets of air extraction shells 36, respectively. The liquid pump 331 extracts external coolant through the liquid extraction pipe. Then, the coolant is injected into the cooling pipe 333 through the drain pipe 332 and returned to the coolant storage end through the return pipe 334. When the high-temperature steam in the extracted gas passes through the housing 32, the steam comes into contact with the spirally arranged cooling pipe 333 and liquefies upon cooling. The liquefied water remains at the bottom of the housing 32. The drain valve 34 is opened periodically to discharge the coolant.
