Referring to fig. 1, 2, 3 and 4, a first aspect of the present application provides a drying apparatus for drying a printing medium 700 output by a printing device 600, where the printing medium 700 is used to carry a printing material, and the printing material may be ink, as an exemplary possible implementation manner, the printing device 600 may form a print content on a surface of the printing medium 700 by spraying the ink onto the surface of the printing medium 700, and the print content may be one or several of a pattern, a text or a color. Print medium 700 may include, but is not limited to, cotton, linen, or chemical fiber cloth, among others. The drying apparatus may include an oven 100, a cloth lifting device 200, and a conveying device 400, the oven 100 may have a receiving chamber for receiving the printing medium 700, and the receiving chamber of the oven 100 may be filled with high temperature gas generated by the hot air blower 900, the high temperature gas being used for heat exchange with the printing material on the surface of the printing medium 700, so that the printing material is denatured and/or a solvent therein is evaporated, so that the printing material is rapidly cured. The cloth lifting device 200 is used for stretching the printing medium 700 output by the printer, for example, the cloth lifting device 200 can be a rotatable roller which is perpendicular to or forms a certain angle with the length direction of the printing medium 700, the roller is made of a material with a high friction coefficient, the length of the roller is not smaller than the width of the printing medium 700, when the roller rotates, the tension is uniformly applied to the printing medium 700 by virtue of the friction force of the surface of the roller, and according to the material characteristics of different printing mediums, the tension of the cloth lifting device 200 to the printing material can be adjusted by adjusting the rotating speed of the roller. When the rotational speed of the roller is greater than the output speed of the output end of the printing apparatus 600, the printing medium 700 will be stretched by the roller friction force and the printing medium 700 will be pulled from the output end of the printing apparatus 600. Conveyor 400 is used to transport print medium 700. Conveyor 400 takes print medium 700 into oven 100 and out of oven 100. Conveyor 400 may be a conveyor belt or a conveyor belt.

As some possible embodiments, the printing medium 700 enters the printing apparatus 600 from the input end of the printing apparatus 600, is output from the output end of the printing apparatus 600 after being printed in the printing apparatus 600, and then one end of the printing medium 700 is connected to the cloth lifting apparatus 200, the cloth lifting apparatus 200 uniformly pulls the printing medium 700 from the output end of the printing apparatus 600 and applies a pulling force to the printing medium 700, so that the printing medium 700 is pulled from the output end of the printing apparatus 600 and uniformly stretched, the number of folds of the printing medium 700 passing through the cloth lifting apparatus 200 is small, the printing medium 700 can be flatly laid on the conveying apparatus 400 and is sent into the oven 100, and the printing material on the printing medium 700 is not gathered due to the existence of the folds, thereby improving the yield of the printing medium 700.

In some possible embodiments, referring to fig. 1, 2 and 3, the oven 100 further includes a support frame 300 disposed at an inlet of the oven 100, the support frame 300 may be two opposite plates disposed on the oven 100 and extending out of the oven 100, or may be a support frame having supporting capability disposed outside the oven 100, the support frame 300 mainly serves to support the cloth lifting device 200 and the conveying device 400, and the cloth lifting device 200 and the conveying device 400 are conveniently mounted and dismounted so as to facilitate maintenance or replacement of the cloth lifting device 200 and the conveying device 400, and the cloth lifting device 200 and the conveying device 400 are disposed on the support frame 300.

In some possible embodiments, referring to fig. 1, 2 and 3, the rotation axis of the cloth lifting roller may be perpendicular to the conveying direction of the conveying device 400, and the cloth lifting device 200 includes the cloth lifting roller and a first driving member for driving the cloth lifting roller to rotate. The first driving member may include, but is not limited to, a motor, for example, when the first driving member is a motor, the motor may be disposed on the support frame 300, and the cloth lifting roller may be provided with a gear, and the gear is meshed with a gear at an output end of the motor, so that the cloth lifting roller rotates. For another example, when the first driving member is a belt, the belt may be used to connect a driving mechanism such as a power source or a pulley of the conveying apparatus 400 to the cloth lifting roller in a driving manner, so that the cloth lifting roller rotates.

In some possible embodiments, since the surface of the printing medium 700 is smooth, in order to prevent relative sliding between the printing medium 700 and the cloth roller, it is preferable to provide an anti-slip structure on the surface of the cloth roller for increasing friction force to the printing medium 700, and the anti-slip structure may include, but is not limited to, anti-slip waves, anti-slip bumps, anti-slip coatings, or the like. The anti-slip structure may be formed on the surface of the cloth lifting roller through an integral molding process, such as an injection molding process; the anti-slip structure can also be formed on the surface of the cloth lifting roller in an adhesive mode, for example, the anti-slip structure is adhered on the surface of the cloth lifting roller after being independently manufactured; the anti-slip coating can be formed on the surface of the cloth lifting roller in a spraying mode, for example, the anti-slip coating is sprayed on the surface of the cloth lifting roller to form an anti-slip surface.

In some possible embodiments, the conveying device 400 includes a conveyor belt and a driving member for moving the conveyor belt. The transmission member may be a pulley driven to rotate by a motor, or may be a gear, a steel chain, a belt, or the like for transmitting torque of the power source to the transmission belt, for example. As a possible example, when the transmission belt is driven by the belt pulley, the driving member may be the belt pulley directly contacting with the transmission belt and driving the transmission belt to move, or may be a gear, a belt, a steel chain, or the like in driving connection with the belt pulley of the transmission belt.

In some possible embodiments, the delivery device 400 further comprises a second driving member drivingly connected to the transmission member, the second driving member being configured to drive the transmission member in motion. Alternatively, the second driving member may drive the transmission member to rotate at a rotational speed less than, greater than, or equal to that of the cloth lifting roller, for example, the second driving member may be a motor or the like; or the transmission piece is in driving connection with the first driving piece, the first driving piece can also be a variable frequency motor, and the variable frequency motor is used for enabling the transmission piece to rotate at a rotating speed smaller than, larger than or equal to that of the cloth lifting roller. The conveyor 400 and the cloth roller can share the same driving member, thereby saving cost. When the rotating speed of the cloth lifting roller is larger than that of the transmission piece, the printing medium 700 stretched by the cloth lifting roller can be continuously spread on the conveying belt in a flat mode, so that the printing medium 700 cannot be stretched again by the conveying belt, and the printing medium 700 is prevented from being torn.

In some possible embodiments, to adapt to the material characteristics of different printing media 700, and avoid that the softer printing media 700 falls into the gap between the cloth lifting device 200 and the conveying device 400 after being separated from the cloth lifting device 200, it is preferable that the cloth lifting device 200 is movably arranged on the support frame 300, and the cloth lifting device 200 may be connected to the support frame 300 by a magnetic attraction manner, or may be mounted on the support frame 300 by a chute arranged on the support frame 300, and the cloth lifting device 200 may be moved to a required position along the chute and fixed. As a possible example, when it is desired to dry a softer cloth, the cloth lifting device 200 may be arranged obliquely above the conveyor 400, i.e. the projections of the cloth lifting device 200 and the conveyor 400 on the horizontal plane coincide, such that the point of fall of the cloth falling from the cloth lifting device 200 is located on the conveyor 400 at a position remote from the end of the conveyor 400, so that softer cloth is prevented from falling into the gap between the conveyor 400 and the cloth lifting device 200.

Since the printing medium 700 is more or less permeated into the printing medium 700 near the cloth lifting device 200, the permeated printing medium is adhered to the surface of the cloth lifting device 200 along with the movement of the printing medium 700, for example, adhered to the surface of a cloth lifting roller, and the printing medium 700 firstly adhered to the cloth lifting roller through the rotation of the cloth lifting roller is adhered to the printing medium 700 later passed through the cloth lifting roller, so that the color-lifting phenomenon is caused, and the yield of the printing medium 700 is reduced. To solve this problem, in one possible embodiment, referring again to fig. 1, 2 and 3, the drying apparatus further includes a non-contact drying device 500, the non-contact drying device 500 being disposed on the support frame 300, the non-contact drying device 500 being located at a side of the cloth lifting device 200 facing away from the conveying device 400. The non-contact type drying device 500 is not in contact with the printing medium 700, and is used for drying the printing medium 700 before passing through the cloth lifting device 200, specifically, drying the printing material permeated on one side of the printing medium 700 near the cloth lifting device 200. The non-contact drying device 500 may include, but is not limited to, an infrared dryer or a hot air dryer, and the infrared dryer is preferable as the non-contact drying device 500 since hot air blown from the hot air dryer may cause disturbance to the printing medium 700 such as cloth, possibly causing wrinkles in the tensioned printing medium 700.

A second aspect of the embodiments of the present application provides a printing system, referring to fig. 4 and 5, the printing system includes a printing apparatus 600 and the aforementioned drying device, where the printing apparatus 600 may include, but is not limited to, a laser printing apparatus 600 and an inkjet printing apparatus 600, and an output end of a printing medium 700 of the printing apparatus 600 is disposed opposite an input end of the printing medium 700 of the drying device.

As before, the printing medium 700 enters the printing apparatus 600 from the input end of the printing apparatus 600, is output from the output end of the printing apparatus 600 after being printed in the printing apparatus 600, and then one end of the printing medium 700 is connected to the cloth lifting apparatus 200, the cloth lifting apparatus 200 uniformly pulls the printing medium 700 from the output end of the printing apparatus 600 and applies a pulling force to the printing medium 700, so that the printing medium 700 is pulled from the output end of the printing apparatus 600 and uniformly stretched, wrinkles are not easily generated on the printing medium 700 passing through the cloth lifting apparatus 200, the printing medium 700 can be flatly laid on the conveying apparatus 400 and is sent into the oven 100, and the printing material on the printing medium 700 is not gathered due to the presence of wrinkles, thereby improving the yield of the printing medium 700.

The printing medium output from the output end of the oven 100 may be accommodated in the cloth carriage 902 by being adjusted by the cloth carriage 901, and the cloth carriage 901 may cause the printing medium to reciprocally fall into the cloth carriage 902, thereby causing the printing medium to be in a folded state in the cloth carriage 902.

In some possible embodiments, the height of the output end of the printing device 600 and the height of the input end of the oven 100 may be horizontal, or the height of the output end of the printing device 600 may be greater than the height of the input end of the oven 100, or the height of the output end of the printing device 600 may be less than the height of the input end of the oven 100.

The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the utility model.
