Description

Technical Field

[0001] The utility model relates to the technical field of denim fabric processing, in particular to a printing mechanism used for denim fabric processing. Background Art

[0002] Denim is a thicker, yarn-dyed warp twill cotton cloth. The warp yarn is dark in color, generally indigo blue, and the weft yarn is light in color, generally light gray or scoured white yarn. It is also called indigo work cloth and is suitable for men's and women's jeans, denim tops, denim vests, denim skirts, etc. During the production process of denim, it is necessary to print and decorate the surface of the fabric.

[0003] However, the existing printing mechanism cannot extract the smoke generated by it in real time during printing, and the denim fabric needs to be manually spread on the bottom of the printing mechanism for printing by workers, which often causes wrinkles, affecting the printing effect and making the operation more cumbersome. Therefore, a printing mechanism for denim fabric processing is proposed to avoid wrinkles on the denim fabric and printing defects, and to extract and purify the generated smoke in real time, thereby improving the quality of denim fabric printing processing.

[0007] By adopting the above technical solution, during operation, the denim fabric is wound around the air inflation roller, and the air inflation roller is driven to rotate by a motor, so that the fabric to be printed can be transported to the bottom of the laser printing machine. After the air inflation roller is inflated with high pressure, the surface part expands, and the denim fabric is tightened to avoid wrinkles that affect the printing effect. The cross bar limits the denim fabric to keep it flat when feeding and discharging the material.

[0008] If you need to print fine details on denim, you can use the cylinder to drive the push plate to move upward, driving the denim to move upward close to the laser printing machine for easy printing;

[0009] The micro motor then drives the reciprocating screw to rotate, thereby driving the sliding sleeve, the support plate and the laser printing machine to move along the slide rail, thereby printing the denim below;

[0010] When the laser printing machine prints on denim fabrics, it will produce odor and gas, which will be sucked out in real time by the exhaust fan, and then purified and filtered through the filter. The filter should be replaced regularly to achieve the effect of improving environmental protection.

[0011] Specifically, the driving end of the motor is connected to the air expansion roller via a rotating shaft, and a cross bar is provided between the connecting blocks at a position corresponding to the bottom of the air expansion roller.

[0012] By adopting the above technical solution, the denim fabric is wound around the air inflation roller, and the air inflation roller is driven to rotate, so that the fabric to be printed can be transported to the bottom of the laser printing machine. After high-pressure inflation, the surface of the air inflation roller partially expands, which tightens the denim fabric to avoid wrinkles that affect the printing effect. The cross bar limits the denim fabric to keep it flat when feeding in and out.

[0013] Specifically, the cylinder is fixed in the groove by bolts, and the push plate is fixed to the top driving end of the cylinder by screws, and the push plate is located at the bottom of the laser printing machine.

[0014] By adopting the above technical solution, if it is necessary to print fine parts of the denim fabric, the cylinder can be used to drive the push plate to move upward, so as to drive the denim fabric to move upward and close to the laser printing machine for printing.

[0015] Specifically, the driving end of the micro motor is connected to the reciprocating screw rod through a rotating shaft.

[0017] By adopting the above technical solution, a micro motor is used to drive the reciprocating screw to rotate, thereby driving the sliding sleeve, the support plate and the laser printing machine to move along the slide rail, so as to print the denim underneath.

[0018] Specifically, a filter screen is installed on the top of the exhaust fan by means of bolts.

[0019] By adopting the above technical solution, the laser printing machine will generate odor and gas when printing on denim fabrics. The odor and gas will be sucked out in real time by an exhaust fan, and then purified and filtered by a filter. The filter should be replaced regularly to achieve the effect of improving environmental protection.
