[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-6 , the present utility model provides a technical solution for an auxiliary printing uniformity device for fabric printing:

[0023] The controller 5 is fixedly connected to the front side of the cleaning and conveying device 4. The cleaning and conveying device 4 is arranged at the rear side inside the applying device 1.

The tension output device 3 is drivingly connected to the cleaning and conveying device 4. The left rear end of the dust collection device 2 is fixedly connected to a holding handle 6.

[0024] The applying device 1 includes an applying frame 11. Four bearing holes 12 are respectively opened on the left and right side walls of the applying frame 11. The eight bearing holes 12 are concentric in pairs, so as to ensure the stability during the rotation of the power rotating shaft 46, the linkage rotating shaft 410 and the two matching rotating shafts 43. The cleaning and conveying device 4 is movably connected in the eight groups of bearing holes 12. The upper and lower left and right side surfaces of the front end of the applying frame 11 are fixedly connected with a positioning plate one 14 and a positioning plate two 16 respectively.

[0025] At the rear ends of both of the first positioning plates 14, dust removal brushes 13 are fixedly connected. The dust removal brushes 13 remove static electricity on the two cleaning conveyor belts 45 and intercept dust and impurities. At the rear ends of both of the second positioning plates 16, static brushes 15 are fixedly connected. The two static brushes 15 and the two dust removal brushes 13 are movably connected to a cleaning transmission device 4. During the rotation of the two cleaning conveyor belts 45, they will also contact and rub against the static brushes 15 fixedly connected to the corresponding two second positioning plates 16, and then the impurities and dust on the fabric can be adsorbed efficiently and with high quality. Dust collection devices 2 are arranged on the front sides of the upper and lower inner ends of the giving frame 11.

[0026] The cleaning transmission device 4 includes a power motor 41. The power motor 41 is fixedly connected to the left side surface of the giving frame 11 through a connecting substrate 42. The left end of a power rotating shaft 46 is fixedly connected to the output shaft of the power motor 41. The right end of the power rotating shaft 46 passes through the corresponding two bearing holes 12 and is fixedly connected to a third reverse gear 48.

The two other interlocking rotating sleeves 44 are respectively fixedly connected to the outer side surfaces at the centers of the two matching rotating shafts 43. The two matching rotating shafts 43 are respectively movably connected in the four groups of bearing holes 12 at the upper and lower ends.

The dust suction ports of the two dust collection pipes 22 are respectively arranged corresponding to the contact positions of the two cleaning conveyor belts 45 and the two dust removal brushes 13. The left ends of the two dust collection pipes 22 both pass through the left side wall of the giving frame 11 and are both fixedly communicated with the upper ends of the dust guiding pipes 23. The other ends of the dust guiding pipes 23 are fixedly communicated with the suction ends of the suction pumps 24 to generate a high suction force to achieve the purpose of collecting dust and impurities. The suction pumps 24 are fixedly connected to the left side surface of the giving frame 11. The rear output ports of the suction pumps 24 are movably connected with a dust collection box 25 through connecting pipes. A carrying handle 6 is fixedly connected to the upper side surface of the dust collection box 25. The dust collection box 25 is composed of filter plates to discharge the excess air and collect the dust for subsequent processing.

[0029] The tensioning output device 3 includes a protective frame 35 to protect the cleaned fabric and facilitate the efficient and uniform printing and dyeing of the subsequent fabric printing and dyeing device. Two discharge shafts 37 are symmetrically and movably connected to both ends of the connecting holes opened at the upper and lower ends of the left and right side walls of the protective frame 35. The right ends of the two discharge shafts 37 both pass through the right side wall of the protective frame 35 and are respectively fixedly connected with a first reverse gear 31 and a second reverse gear 32 to make the two discharge shafts 37 rotate synchronously and reversely to pull the conveyed fabric and discharge the fabric through the discharge slot 38 into the fabric printing and dyeing device for uniform printing and dyeing. The first reverse gear 31 and the second reverse gear 32 are in transmission connection. The outer end of the right side of the upper discharge shaft 37 is fixedly connected with a synchronous sprocket 33.

Discharge slots 38 are opened at the rear ends of the opposite surfaces of the two discharge rollers 36 corresponding to the protective frame 35. The output end of the controller 5 is electrically connected to the input ends of the suction pump 24 and the power motor 41 to facilitate the control and use by the corresponding staff.

[0030] The specific operation mode of the present utility model:

[0031] Before dyeing the fabric, first pass the fabric between two cleaning conveyor belts 45, between two discharging rollers 36, and connect the discharging square groove 38 with the corresponding dyeing device. Then, the power motor 41 can be started to rotate by the controller 5. When the power motor 41 rotates, it will be positioned through the connecting substrate 42 to ensure the rotational stability. The rotation of the power motor 41 will drive the rotation of the power rotating shaft 46. The rotation of the power rotating shaft 46 will drive the reverse rotation of the linkage rotating shaft 410 through the cooperation of the reverse gear three 48 and the reverse gear four 49. The synchronous reverse rotation of the power rotating shaft 46 and the reverse rotating shaft will drive the two cleaning conveyor belts 45 to rotate synchronously in the reverse direction through the corresponding two linkage sleeves 44. During this process, the stability of the rotation will also be ensured through the cooperation of the corresponding two linkage sleeves 44 fixedly connected to the two matching rotating shafts 43. During the rotation of the power rotating shaft 46, the linkage rotating shaft 410, and the two matching rotating shafts 43, the rotational stability will be ensured through the support and positioning of the multiple bearing holes 12 opened on the giving frame 11. During the rotation of the power rotating shaft 46, the driving sprocket 47 will be driven to rotate. The rotation of the driving sprocket 47 will drive the corresponding discharging shaft 37 to rotate. When the corresponding discharging shaft 37 rotates, it will drive the other discharging shaft 37 to rotate synchronously in the reverse direction through the cooperation of the reverse gear one 31 and the reverse gear two 32. During the rotation of the two discharging shafts 37, the rotational stability will be ensured through the positioning and support of the connecting holes opened on the protective frame 35. Then, the two discharging rollers 36 can be driven to rotate stably in the reverse direction to squeeze and discharge the fabric from the discharging square groove 38. During this process, the two cleaning conveyor belts 45 will contact the fabric in the opposite direction to the movement of the fabric. During the rotation of the two cleaning conveyor belts 45, they will also be in contact and friction with the static brushes 15 fixedly connected to the corresponding two positioning plates two 16. Then, the impurities and dust on the fabric can be adsorbed efficiently and with high quality. When the two cleaning conveyor belts 45 continue to rotate in the reverse direction, the static electricity on the two cleaning conveyor belts 45 will be removed and the dust and impurities will be intercepted by the dust removing brushes 13 fixedly connected to the corresponding two positioning plates one 14. At the same time, the suction pump 24 controlled by the controller 5, the dust guiding pipe 23, the two fixed connecting plates 21, and the two dust collecting pipes 22 will suck and discharge the dust and impurities into the dust collecting box 25 for collection. After collecting a certain amount, the dust collecting box 25 can be moved to be separated from the suction pump 24 by holding the handle 6 for convenient treatment of the dust inside. Then, the fabric can be dyed uniformly and with high quality through the subsequent connected fabric dyeing device.
