Specifically, the machine body 1 is further rotatably provided with a plurality of guide rollers 15, and the plurality of guide rollers 15 are respectively located at respective inflection points of the fabric running path.
In practical application, the external textile fabric is driven by the first feeding roller 11, the second feeding roller 12, the first discharging roller 13 and the second discharging roller 14 to sequentially pass through the front printing device 21, the first drying device 31, the back printing device 22 and the second drying device 32; when the textile material passes through the front printing device 21, the front printing device 21 carries out digital color printing on the front of the textile material so as to color print patterns on the front of the textile fabric; after the front surface of the textile fabric is color-printed with the pattern, in order to prevent the phenomenon of ink permeation from occurring on the back surface of the textile fabric, the first drying device 31 is used for heating the textile fabric, and the heat plays a role in drying and fixation on the surface of the textile fabric so as to solve the problem of ink permeation from occurring on the back surface of the textile fabric; similarly, after the textile fabric passes through the reverse side printing device 22 and the reverse side color printing of the textile fabric is completed, the second drying device 32 also heats the textile fabric, so that the surface of the textile fabric plays a role in drying and color fixation.

The invention has simple and compact structure, stable and reliable operation and effectively improves the production efficiency and the printing quality.
In the technical solution, referring to fig. 1 and 3, the first tensioning device 41 includes a rotating cantilever 411 rotatably disposed on the machine body 1, a roller 412 rotatably disposed at one end of the rotating cantilever 411, a balancing weight 413 slidably disposed on the rotating cantilever 411, a sensing member 414 disposed at one end of the rotating cantilever 411 away from the roller 412, and an upper sensor 415 and a lower sensor 416 disposed at the upper side and the lower side of the sensing member 414, respectively, where one end of the rotating cantilever 411 close to the sensing member 414 is rotatably connected with the machine body 1. Specifically, the body 1 is further provided with a third driving mechanism and a fourth driving member mechanism for driving the first feed roller 11 to rotate and for driving the second feed roller 12 to rotate, respectively. The upper sensor 415 and the lower sensor 416 are electrically connected to a third driving mechanism.

Therefore, in this embodiment, the roller 412 always rolls and abuts against the textile fabric between the first feeding roller 11 and the second feeding roller 12, the rotating cantilever 411 rotates downward under the gravity action of the balancing weight 413, and the roller 412 is driven to press down the textile fabric, so that the textile fabric always maintains constant tension in the conveying process, and the phenomenon that the textile fabric is deformed and stretched to cause deviation is avoided, specifically, a user can adjust the position of the balancing weight 413 on the rotating cantilever 411 to adjust the pressure of the roller 412 on the textile fabric, so as to realize the adjustment of the tension of the textile fabric; when the first feeding roller 11 is excessively fed, the roller 412 descends to keep pressing down the textile fabric to ensure the tension thereof, and the rotary cantilever 411 rotates downwards until the sensing element 414 contacts with the upper sensor 415, and the upper sensor 415 feeds back information to the third driving mechanism and commands the third driving mechanism to stop driving the rotation of the first feeding roller 11, so as to stop the conveying of the textile fabric, thereby preventing the textile fabric from becoming excessively loose; after the first feeding roller 11 stops rotating, the second feeding roller 12 continues rotating to drive the textile fabric to enter the front printing device 21, at this time, the movement of the textile fabric drives the roller 412 to rise, the rising of the roller 412 drives the rotating cantilever 411 to rotate upwards, until the sensing piece 414 contacts with the lower sensor 416, the lower sensor 416 feeds information back to the third driving mechanism and commands the third driving mechanism to start driving the rotation of the first feeding roller 11, so that the external textile fabric continues feeding, and the phenomenon of overstretching of the textile fabric is prevented. The first tensioning device 41 has a simple and smart structure, is stable and reliable to operate, and automatically adjusts the position of the roller 412 through the lever principle, so as to provide constant tension for the textile fabric, thereby preventing the textile fabric from deformation, stretching and deviation in the printing and conveying process, ensuring that the feeding amount of the textile fabric in each printing process can be accurately controlled, and greatly improving the printing efficiency and the printing quality of the invention.

In practical application, the outside textile material passes through the gap between the first feeding roller 11 and the detecting roller 52, when the uneven textile material is laid through the gap, the detecting roller 52 is jacked up by the uneven textile material, so that the detecting roller 52 is abutted against the proximity switch 53 to start the proximity switch 53, and at the moment, the first feeding roller 11 stops rotating to stop feeding the textile material, and prevent the unqualified textile material from entering the front printing device 21. The feeding detection device 5 has a simple and compact structure, is stable and reliable to operate, and effectively improves the printing quality of the printing device.
In this solution, referring to fig. 1, one side of the first feeding roller 11 is slidably provided with a roller seat 111, a pressing roller 112 rotatably disposed on the roller seat 111, and a third driving member 113 for driving the roller seat 111 to approach or separate from the first feeding roller 11.
In practical application, the third driving member 113 drives the roller seat 111 to approach the first feeding roller 11, the roller seat 111 drives the pressing roller 112 to move and make the pressing roller roll contact with the first feeding roller 11, and when in operation, the pressing roller 112 can press the textile fabric against the first feeding roller 11, so that the first feeding roller 11 can stably drive the textile fabric to move, and further the working stability of the invention is improved. In the present embodiment, the nip roller 112 is provided on one side of the second feed roller 12, one side of the first discharge roller 13, and one side of the second discharge roller 14.
The present invention is not limited to the preferred embodiments, but is intended to be limited to the following description, and any modifications, equivalent changes and variations in light of the above-described embodiments will be apparent to those skilled in the art without departing from the scope of the present invention.
