Description

Technical Field

[0001] This utility model relates to the field of printing and dyeing equipment technology, and in particular to a pile raising mechanism and transfer printing machine for plush fabric. Background Technology

[0002] In transfer printing, a pattern pre-printed on transfer paper is typically transferred to the fabric surface via heat pressing, enabling rapid imaging of complex designs. This process offers advantages such as high pattern precision, rich color gradation, and simplified procedures, making it widely used in printing on various textile fabrics.

[0003] However, for plush fabrics, their surface has a certain degree of pile structure, and the pile is affected by a combination of factors such as temperature, pressure, and time during heat pressing and transfer. The distribution, flatness, and deformation after pressure of the pile directly affect the transfer effect and image clarity. Currently, heat transfer processing for plush fabrics mostly adopts a planar pressing structure, that is, placing transfer paper and plush fabric between a heated pressure plate and a supporting platform, and achieving pattern transfer through overall heating and pressure. However, this method completely flattens the pile fibers during the transfer process, and it is difficult to restore the original three-dimensional structure after cooling and setting, resulting in a weakened pile feel and a flat, stiff surface.

[0004] On existing production lines, the pressed plush fabric usually needs to be manually combed to restore the upright state of the pile and its soft feel. However, manual operation is inefficient, which in turn reduces the overall production efficiency and makes it difficult to meet the needs of continuous and automated printing production.

[0016] Optionally, the static electricity removal component includes a mounting frame and several ion needles. The mounting frame is detachably mounted on one side of the exhaust duct extending along its own length. The several ion needles are evenly spaced on the mounting frame along the width of the plush fabric, with the discharge end of each ion needle facing downwards, so that the ion needles release ions to neutralize the static electricity on the surface of the plush fabric.

[0017] Optionally, the conveyor roller assembly includes a first conveyor roller and a second conveyor roller, wherein:

[0018] The first and second conveying rollers are rotatably mounted on the frame. The first and second conveying rollers are arranged parallel to each other along the conveying direction of the plush fabric. A conveying space extending in the vertical direction is formed between the first and second conveying rollers. The suction end of the suction assembly is located in the conveying space.

[0019] The first conveyor roller and the second conveyor roller are connected by a drive mechanism. The drive end of the drive assembly is connected to the first conveyor roller. The drive assembly drives the first conveyor roller to rotate so that the first conveyor roller and the second conveyor roller rotate synchronously in the same direction.

[0026] 2) By setting three air extraction pipes, which are evenly spaced along the width of the fabric at their connection ends with the negative pressure chamber, the multi-point uniform air supply to the negative pressure chamber is realized, which further improves the uniformity of air pressure inside the negative pressure chamber, avoids insufficient local negative pressure leading to insufficient napping, and ensures consistent napping effect across the entire fabric.

[0027] 3) The mounting bracket and several ion needles work together to ensure sufficient ion coverage and more thorough static elimination.

[0032] Please see Figure 1 and Figure 2 As shown in the embodiment of this application, a pile-raising mechanism for plush fabric includes a frame 10, a drive assembly 20, a conveyor roller group 30, and an air extraction assembly 40, wherein:

[0033] The conveyor roller assembly 30 is detachably mounted on the frame 10, the fixed end of the drive assembly 20 is mounted on the frame 10, the drive end of the drive assembly 20 is connected to the conveyor roller assembly 30, and the drive assembly 20 is configured to drive the plush fabric 50 to move in a preset direction via the conveyor roller assembly 30.

[0034] A pile-raising station 60 is provided above the movement path of the plush fabric 50. The exhaust end of the air extraction component 40 is positioned downwards at the pile-raising station 60 and extends along the width direction of the plush fabric 50. The air extraction component 40 is configured to extract the air above the plush fabric 50 at the pile-raising station 60 to create a negative pressure that sucks up the plush on the plush fabric 50.

[0035] The drive component 20 drives the plush fabric 50 to be raised through the raising station 60. With the help of the suction component 40, a negative pressure is formed above the plush fabric 50 at the raising station 60, which can effectively suck up the fluff, reduce the need for manual finishing, and improve the degree of automation and production efficiency.

[0036] In one embodiment, the extraction assembly 40 includes an extraction component 41, an extraction duct 42, and at least one extraction pipe 43, wherein:

[0037] The exhaust duct 42 is provided with a negative pressure chamber 420 extending along the width direction of the plush fabric 50, and the opening of the negative pressure chamber 420 faces downward.

[0038] The air extraction component 41 is located on one side of the frame 10. One end of the air extraction pipe 43 is connected to the air extraction component 41, and the other end of the air extraction pipe 43 is connected to the negative pressure chamber 420. The air extraction component 41 is configured to extract air from the negative pressure chamber 420 through the air extraction pipe 43 so that a negative pressure is formed in the negative pressure chamber 420.

[0039] Specifically, the exhaust component 41 is configured as an exhaust fan.

[0040] By combining the air extraction component 41, the air extraction duct 42, and the air extraction pipe 43, a simple and stable air extraction assembly 40 is provided, ensuring the efficiency and effect of napping.

[0041] In one embodiment, the air extraction assembly 40 includes three air extraction pipes 43, and the ends of the three air extraction pipes 43 connected to the negative pressure chamber 420 are evenly spaced along the width direction of the plush fabric 50.

[0042] By setting three air extraction pipes 43, which are evenly spaced along the width of the fabric at their connection ends with the negative pressure chamber 420, the multi-point uniform air supply of the negative pressure chamber 420 is realized, which further improves the uniformity of air pressure inside the negative pressure chamber 420, avoids insufficient local negative pressure leading to insufficient napping, and ensures that the napping effect of the entire fabric is consistent.

[0043] In one embodiment, the exhaust assembly 40 further includes a lifting assembly 44, the fixed end of which is disposed on the frame 10, and the driving end of the lifting assembly 44 is connected to the exhaust duct 42. The lifting assembly 44 is configured to drive the exhaust duct 42 to rise and fall so that the opening of the negative pressure chamber 420 approaches or moves away from the plush fabric 50 in the vertical direction.

[0044] Specifically, the lifting assembly 44 is a linear module composed of a motor and a ball screw linear transmission pair.

[0045] The lifting component 44 drives the exhaust duct 42 to rise and fall, and the distance between the opening of the negative pressure chamber 420 and the fabric can be adjusted according to the fabric thickness or process requirements to make the suction effect optimal, improve adaptability and napping quality.

[0046] In one embodiment, the pile raising mechanism for the plush fabric further includes an electrostatic removal component 70, which is disposed on the feed side of the pile raising station 60 and is configured to remove static electricity from the plush fabric 50 to be piled.

[0047] The static electricity of the fabric is neutralized by the static removal component 70 before the pile raising station 60, which can prevent the pile from sticking or clumping due to static electricity, and makes the subsequent suction action more stable and the pile more naturally upright.

[0048] In one embodiment, the static electricity removal component 70 includes a mounting frame 71 and a plurality of ion needles 72. The mounting frame 71 is detachably disposed on one side of the exhaust duct 42 extending along its own length direction. The plurality of ion needles 72 are evenly spaced on the mounting frame 71 along the width direction of the plush fabric 50. The discharge end of each ion needle 72 is disposed downward so that the ion needles 72 release ions to neutralize the static electricity on the surface of the plush fabric 50.

[0049] The mounting bracket 71 and several ion needles 72 work together to ensure sufficient ion coverage and more thorough static electricity elimination. The detachable structure of the mounting bracket 71 facilitates maintenance and replacement without affecting the overall operation of the mechanism, thus improving the reliability of the equipment.

[0050] In one embodiment, the conveyor roller assembly 30 includes a first conveyor roller 31 and a second conveyor roller 32, wherein:

[0051] The first conveying roller 31 and the second conveying roller 32 are rotatably mounted on the frame 10. The first conveying roller 31 and the second conveying roller 32 are arranged parallel to each other along the conveying direction of the plush fabric 50. A conveying space extending in the vertical direction is formed between the first conveying roller 31 and the second conveying roller 32. The suction end of the suction assembly 40 is arranged in the conveying space.

[0052] The first conveying roller 31 and the second conveying roller 32 are connected by a transmission. The driving end of the driving assembly 20 is connected to the first conveying roller 31. The driving assembly 20 drives the first conveying roller 31 to rotate so that the first conveying roller 31 and the second conveying roller 32 rotate synchronously in the same direction.

[0053] Specifically, the drive mechanism is set as a drive module consisting of a motor and a transmission wheel. The motor drives the first conveyor roller 31 to rotate, and then drives the second conveyor roller 32 to rotate synchronously through the transmission wheel.

[0054] By having the first conveying roller 31 and the second conveying roller 32 arranged parallel to each other along the fabric conveying direction, the fabric can be kept flat during the conveying process. This makes it easier for the suction end of the suction component 40 to accurately apply negative pressure to the pile fabric 50 below, so as to achieve uniform suction and erection of the pile, further improving the consistency of the pile effect and adapting to the needs of automated continuous production.

[0055] In one embodiment, the pile raising mechanism for the plush fabric further includes a guide roller 81 and a tension roller 80. The guide roller 81 is disposed on the feed side of the pile raising station 60 and located obliquely below the first conveying roller 31. The outer periphery of the guide roller 81 is covered with a friction surface 810, which is configured to increase the friction between the guide roller 81 and the plush fabric 50.

[0056] Tensioner roller 80 is disposed between first conveyor roller 31 and guide roller 81, and tensioner roller 80 is configured to increase the tension of plush fabric 50.

[0057] Specifically, the friction surface 810 is configured to tightly wrap the outer periphery of the guide roller 81 with a polyester or nylon fabric with a high coefficient of friction.

[0058] The cooperation of guide roller 81 and tension roller 80 enhances fabric tension, ensuring a smooth and even fabric surface, and guaranteeing uniform napping.

[0059] In one embodiment, the pile raising mechanism for the plush fabric further includes an operating table 90, which is located on the feed side of the frame 10 extending along the width direction of the plush fabric 50. The plush fabric 50 to be raised passes under the operating table 90 so that the operator can adjust the operation of the pile raising station 60 on the operating table 90.

[0060] By setting up an operating table 90 on the feeding side of the frame 10, the fabric to be piled passes under the operating table 90. Without affecting the conveying of the pile fabric 50, the operator can easily observe the piled situation in real time, adjust the equipment parameters in a timely manner, and improve the convenience of operation.
