Description

Technical Field

[0001] The invention relates to the technical field of thermal transfer, in particular to a thermal transfer device for clothing fabrics and a thermal transfer process thereof. Background Art

[0002] Sublimation thermal transfer is an emerging printing process that is widely used in the production of polyester fiber clothing. It prints the mirror image of the high-resolution image to be printed on the clothes with thermal sublimation ink on the sublimation paper, and then puts the patterned side of the sublimation paper against the fabric and feeds them into the thermal sublimation equipment together.

[0003] In the thermal sublimation equipment, the thermal sublimation ink on the sublimation paper is sublimated by heat. The adhesion rate of gaseous thermal sublimation ink to polyester fiber is much higher than that to paper fiber. Therefore, most of the thermal sublimation ink will separate from the sublimation paper and be adsorbed onto the cloth stacked with the thermal transfer paper.

[0004] In the existing equipment, the cut cloth is laid on the sublimation paper manually. Since the cloth may have wrinkles that are not found manually during manual laying, the printing is misaligned when the cloth and the sublimation paper enter the thermal transfer host. Summary of the invention

[0005] In order to overcome the technical defects of the prior art, the present invention provides a thermal transfer device for clothing fabrics and a thermal transfer process thereof, which ensures the printing effect.

[0006] The technical solution adopted by the present invention is:

[0009] Preferably, the sublimation paper winding device is rotatably mounted on the lower side of the cloth input platform.

[0010] Preferably, the rotary conveying device comprises a cloth rotary active roller, a cloth rotary passive roller and a rotary conveyor belt, the cloth rotary active roller and the cloth rotary passive roller are rotatably installed on the cloth input platform, the rotary conveyor belt is wound around the cloth rotary active roller and the cloth rotary passive roller, and the rotary conveyor belt is provided with a smoothing plate and a plurality of hooks.

[0011] Preferably, the rotary conveyor belt is provided with two smoothing plates and two rows of hooks, and the intervals between the hooks in each row and the corresponding smoothing plates are equal.

[0012] Preferably, the vibrating smoothing device is a vibrating roller.

[0013] Preferably, the vibration eliminating device includes an air suction plate, and the air suction plate attracts the rotary conveyor belt upward.

[0014] The thermal transfer process of clothing fabric thermal transfer equipment, using clothing fabric thermal transfer equipment, includes the following steps:

[0015] S1: Lay the fabric on the sublimation paper with printed patterns;

[0016] S2: The vibration smoothing device and the vibration eliminating device are started at the same time, and the wrinkled fabric is smoothed by the vibration smoothing device, and the fabric that cannot be smoothed is intercepted when passing through the hook, and the rotary conveying device rotates to carry the fabric out;

[0030] The present invention will be further described below in conjunction with the accompanying drawings:

[0031] like Figure 1 and Figure 3 As shown, this embodiment provides a clothing fabric thermal transfer device, including a thermal transfer host 1, a fabric input platform 2 and a fabric rotating system 3, the fabric input platform 2 is installed at the input end of the thermal transfer host 1, the fabric input platform 2 is used to support the sublimation paper 4 and the fabric 5 on the sublimation paper 4, the fabric rotating system 3 includes a rotary conveying device 31, a vibration smoothing device 32 and a vibration elimination device 33, the rotary conveying device 31 is provided with a smoothing plate 34 and a plurality of hooks 35, when the smoothing plate 34 is conveyed to the vicinity of the fabric 5, the smoothing plate 34 is farther away from the thermal transfer host 1 than each corresponding hook 35 (see Figure 2 The position relationship between the smoothing plate 34 and the hook 35 located at the lower side in the figure), the vibration eliminating device 33 and the vibration smoothing device 32 are both installed on the cloth input platform 2, the vibration eliminating device 33 corresponds to the position of each hook 35, and the vibration smoothing device 32 corresponds to the position of the smoothing plate 34. The cloth 5 is first smoothed by the vibration of the smoothing plate 34 and the vibration smoothing device 32. The cloth 5 that cannot be smoothed is hooked by the hook 35 due to its high height, and then the rotary conveying device 31 retreats and pulls the cloth 5 out, thereby ensuring the printing effect.

[0032] Specifically, the thermal transfer host 1 includes a supporting belt conveying device 11, a heating roller 12 and a sublimation paper winding device. The sublimation paper winding device is installed on the lower side of the cloth input platform 2. The heating roller 12 and the supporting belt conveying device 11 are fitted and rolled. The supporting belt conveying device 11 is wound with a supporting belt 6. The sublimation paper 4 is laid with a cloth 5. The cloth 5 follows the sublimation paper 4 and enters between the heating roller 12 and the sublimation paper winding device, thereby heating the sublimation paper 4, so that the ink on the sublimation paper 4 is transferred to the cloth 5. The used sublimation paper 4 is wound by the sublimation paper winding device, and the cloth 5 falls under the action of gravity after the sublimation paper 4 is wound by the sublimation paper winding device. The supporting belt conveying device 11 is used to convey the supporting belt 6, and the supporting belt 6 and the sublimation paper 4 are clamped between the cloth 5.

[0033] Specifically, the sublimation paper winding device is rotatably installed on the lower side of the cloth input platform 2, thereby realizing the winding of the used sublimation paper.

[0034] Specifically, the rotary conveying device 31 includes a cloth rotary active roller 311, a cloth rotary passive roller 312 and a rotary conveyor belt 313. The cloth rotary active roller 311 and the cloth rotary passive roller 312 are rotatably installed on the cloth input platform 2. The rotary conveyor belt 313 is wound around the cloth rotary active roller 311 and the cloth rotary passive roller 312. The rotary conveyor belt 313 is provided with a stroking plate 34 and a plurality of hooks 35, so that the stroking plate 34 can vibrate and press down the wrinkled cloth 5. After the hooks 35 hook the wrinkled cloth 5 that is not pressed down, the cloth 5 is withdrawn under the drive of the rotary conveyor belt 313 ( Figure 2 As shown in the figure, when the cloth 5 is pulled out, the cloth rotating active roller 311 and the cloth rotating passive roller 312 both rotate counterclockwise).

[0035] Specifically, in order to ensure that there are always hooks 35 close to the cloth 5, two smoothing plates 34 and two rows of hooks 35 are provided on the rotary conveyor belt 313, and the spacing between each row of hooks 35 and the corresponding smoothing plates 34 is equal. In this way, after one row of hooks 35 hooks out the cloth 5, the other row of hooks 35 will be transported downward under the drive of the rotary conveyor belt 313. While removing the wrinkled cloth 5, it is ensured that there are still hooks 35 that can hook the cloth 5. Since the spacing between each row of hooks 35 and the corresponding smoothing plates 34 is equal, when the hooks 35 move to the lower side of the vibration elimination device 33, the corresponding smoothing plates 34 are just located on the lower side of the vibration smoothing device 32.

[0036] Specifically, the vibration smoothing device 32 is a vibration roller, on which a vibration motor is installed. The vibration roller can vibrate the rotary conveyor belt 313, so that the rotary conveyor belt 313 can drive the smoothing plate 34 to vibrate and flatten the wrinkled cloth 5 passing through the bottom of the rotary conveyor belt 313.

[0037] Specifically, the vibration elimination device 33 includes an air suction plate 331, which attracts the rotary conveyor belt 313 upward to prevent the hooks 35 from accidentally touching the normal cloth 5 under the vibration of the vibration roller. That is to say, the air suction plate 331 is connected to the negative pressure fan so that the height of the vibrating rotary conveyor belt 313 is restrained by the air suction plate 331 when passing the position of the air suction plate 331, so that the hooks 35 only hook the cloth 5 that is truly wrinkled and curled.

[0038] In addition, the cloth rotating active roller 311 is installed on the output end of the motor. In order to start the cloth rotating active roller 311 in time when the hook 35 hooks the cloth 5, it is possible to manually observe whether the cloth 5 stops, and then start the motor to rotate according to a preset number of revolutions. The control of the number of revolutions of the motor is a conventional existing technology implemented using an encoder, which will not be described here. A visual camera can also be used to automatically take pictures of the cloth 5 for comparison. When the cloth 5 is not completely photographed, it cannot be displayed that it is hooked. The controller controls the starter motor to rotate the preset number of revolutions, so that the cloth rotating active roller 311 rotates. After the cloth 5 is pulled upward, the cloth 5 is manually removed.

[0039] The preset number of revolutions of the motor mentioned above is determined by the distance between the hook 35 and the adjacent stroking plate 34 (please note that the adjacent stroking plate 34 here means the stroking plate 34 that is not used in conjunction with the hook 35). The specific calculation method is to sum the diameter of the cloth rotating active roller 311 plus twice the thickness of the rotary conveyor belt 313, and then multiply it by pi to obtain the stroke of the rotary conveyor belt 313 after the cloth rotating active roller 311 rotates one circle, and then divide the distance between the hook 35 and the adjacent stroking plate 34 by the stroke of the cloth rotating active roller 311 rotating one circle to obtain the number of revolutions of the motor in a single rotation.

[0040] The thermal transfer process of clothing fabric thermal transfer equipment, using clothing fabric thermal transfer equipment, includes the following steps:

[0041] S1: Laying a cloth 5 on the sublimation paper 4 on which a pattern has been printed;

[0042] S2: The vibration smoothing device 32 and the vibration eliminating device 33 are started at the same time, and the wrinkled cloth 5 is smoothed when passing through the vibration smoothing device 32, and the cloth 5 that cannot be smoothed is intercepted when passing through the hook 35, and the rotary conveying device 31 rotates to carry the cloth 5 out;

[0043] S3: Lay the cloth 5 again on the vacated sublimation paper 4.
