[0036] The inkjet printing device can mostly perform printing operation on printing materials such as cloth and film materials. The printing materials can be wound to form a roll, so that the printing device can support the roll by a material rack, so that the printing device can continuously supply the printing materials to the printing device for printing operation by the rotation of the roll. However, the material rack of the printing device mostly uses a rotating shaft to support the roll, so that the roll rotates on the rack body to feed the material. However, the material rack usually does not have an axial limiting structure for the rotating shaft, so that the rotating shaft drives the roll to rotate on the material rack, which is easy to cause a certain axial displacement, and further causes the position of the printing material entering the printing device to deviate, which reduces the feeding stability of the printing device and affects the printing effect of the printing device.

[0037] It can be understood that the inkjet printing device can include but is not limited to a DTF printer (Direct to Film), a DTG printer (Direct to Garment), a general inkjet printer, etc., and the printing material worked by the inkjet printing device can include but is not limited to cloth, film material, paper, etc. By winding the printing material into a roll, the roll can be sleeved on the rack, and the printing material can be conveniently conveyed to the printing device by rotating. In order to ensure the stable rotation and release of the roll, the roll is usually sleeved on the rotating shaft, and bearings are arranged between the two ends of the rotating shaft and the rack body, so that the rotating shaft can smoothly rotate and release the printing material. During the rotation and feeding of the roll driven by the rotating shaft, the bearings and the support will be worn to some extent, and long-term use will easily cause the bearings to loosen or the mounting of the support, bearings and rotating shaft to loosen, which will easily cause the rack to shake and the roll to axially deviate during feeding, affecting the service life and stable feeding of the rack. Therefore, the rack usually needs to be replaced or repaired after the inkjet printing device is used for a certain period of time, which increases the cost of the inkjet printing device. In view of the above problems, the utility model provides a rack 100.

[0038] Please refer to Figures 1 to 12 In an embodiment of the utility model, the rack 100 is used for supporting the roll 300, and includes a support 10, a bearing shaft 30, a first support 331 and a second support 333. The bearing shaft 30 is fixed to the support 10 and is used for sleeving the roll 300. The first support 331 is rotatably sleeved on the bearing shaft 30. The second support 333 is rotatably sleeved on the bearing shaft 30 and is spaced apart from the first support 331. The first support 331 and the second support 333 are respectively used for supporting two ends of the roll 300.

[0039] The rack 100 can form an overall support structure by using the support 10. The support 10 can be a hanging bracket 11 connected and fixed on a main machine of the processing system 1000, or the support 10 can be a tripod, a square rack body or the like that can realize independent support, so that the support 10 can play a relatively stable supporting role and ensure the bearing and support of the bearing shaft 30 and the roll 300 by the support 10. Of course, the support 10 can also adopt other structural forms, and the structure and material of the support 10 are not limited in the application, as long as the bearing and support requirements of the bearing shaft 30 and the roll 300 can be met. The main machine in the processing system 1000 is taken as an example of the inkjet printing device.

[0040] The material rack 300 can be fixedly installed on the support 10. For example, a clamping groove matched with the end of the bearing shaft 30 can be formed on the support 10, so that the bearing shaft 30 is clamped and installed on the support 10. Alternatively, the end of the bearing shaft 30 can be fastened on the support 10 by using a bolt, a screw or the like. Alternatively, the end of the bearing shaft 30 can be clamped on the support 10 by using a clamping sleeve. The application does not limit the fixing and installation mode of the bearing shaft 30 on the support 10. In addition, the bearing shaft 30 can be in a detachable connection with the support 10, so that the material rack 100 can load the material roll 300 by removing the bearing shaft 30 on the support 10. By sleeving the first support 331 and the second support 333 which can rotate on the bearing shaft 30, the first support 331 and the second support 333 can be arranged at a length interval of the material roll 300, and then the first support 331 and the second support 333 can be used to support the two ends of the material roll 300 on the bearing shaft 30, so that the first support 331 and the second support 333 drive the material roll 300 to rotate on the bearing shaft 30 to release the printing material, and stable feeding of the material rack 100 is realized. The first support 331 and the second support 333 can be a winding drum structure which is sleeved on the bearing shaft 30, and the first support 331 and the second support 333 can be respectively inserted into the two ends of the material roll 300 to support the material roll 300. Alternatively, the first support 331 and the second support 333 can be a rotating ring which is rotatably arranged on the bearing shaft 30, and the rotating ring can be used to support the material roll 300 by clamping the two ends of the central shaft of the material roll 300. The rotating arrangement of the first support 331 and the second support 333 on the bearing shaft 30 and the supporting mode of the material roll 300 are various, and the application does not limit them.

[0041] Therefore, by using the fixed bearing shaft 30 and the cooperation connection of the first support 331 and the second support 333, the first support 331 and the second support 333 can be better concentrically assembled with the bearing shaft 30, the eccentric rotation of the material roll 300 on the bearing shaft 30 can be effectively avoided, the shaking of the material rack 100 during the rotation of the material roll 300 can be reduced, the collision and wear between the components of the material rack 100 can be reduced, the material rack 100 can realize more stable and reliable feeding work, and the overall structural stability and reliability of the material rack 100 can be improved. By fixing the bearing shaft 30 on the support 10, the axial deviation of the bearing shaft 30 on the support 10 can be prevented. At this time, by using the cooperation connection of the first support 331 and the second support 333, the directional feeding of the material roll 30 by the material rack 100 can be ensured, the deviation of the printing material during the feeding process can be avoided, the processing system 1000 can realize more accurate processing effect, and the practicability and reliability of the material rack 100 can be further improved.

[0042] The technical scheme of the utility model discloses a bearing shaft 30 is fixedly arranged on the support 10, and the first support piece 331 and the second support piece 333 are rotatably sleeved on the bearing shaft 30 to support and fix the material roll 300, so that the first support piece 331 and the second support piece 333 can drive the material roll 300 to rotate on the bearing shaft 30 to feed, the axial deviation of the bearing shaft 30 on the support 10 is prevented, the abrasion of the bearing shaft 30 and the support 10 is reduced, and the deviation of the printing material in the conveying process is better prevented, and the feeding effect of the material rack 100 is more stable and reliable.

[0043] Referring to Figure 3 And Figure 4 In an embodiment of the utility model, the support 10 includes two brackets 11 oppositely arranged along the axial direction of the bearing shaft 30, and the two brackets 11 are respectively provided with a penetrating installation slot 113, the top of the installation slot 113 is provided with an opening, and the two ends of the bearing shaft 30 are respectively inserted into the installation slot 113 of the two brackets 11.

[0044] In the embodiment, the support 10 can support the two ends of the bearing shaft 30 by using the two brackets 11, so that the bearing shaft 30 can be stably arranged on the support 10, and the stable rotation feeding of the material roll 300 is ensured. At this time, the installation slot 111 can be arranged on the two brackets 11, the installation slot 111 is arranged through the bracket 11, and the slot opening of the installation slot 111 is arranged on the top surface of the bracket 11, so that the bearing shaft 30 can be installed on the support 10 from top to bottom, the end of the bearing shaft 30 can be stably accommodated in the installation slot 111 through the slot opening of the installation slot 111, and the assembly convenience and reliability of the bearing shaft 30 and the support 10 are improved.

[0045] At this time, the rack 100 can be connected and arranged with the first limiting piece 51 on the at least one bracket 11, the first limiting piece 51 can be movably arranged on the bracket 11, so that the first limiting piece 51 can be moved to a pressing position towards the bearing shaft 30, the top surface of the bearing shaft 30 is pressed by the first limiting piece 51, so that the bearing shaft 30 can be better fixed and installed in the mounting groove 113, and the movement of the bearing shaft 30 on the bracket 11 is limited; when the bearing shaft 30 needs to load the roll 300, the first limiting piece 51 can be moved away from the bearing shaft 30 to a release position, so as to release the pressing and fixing of the bearing shaft 30 by the first limiting piece 51, so that the bearing shaft 30 can be stably separated from the mounting groove 113. Therefore, the top surface of the bearing shaft 30 is pressed by the first limiting piece 51 on the bracket 11, so that the first limiting piece 51 cooperates with the groove bottom wall of the mounting groove 113 to clamp the opposite sides of the bearing shaft 30 in the axial direction, effectively limiting the axial movement of the bearing shaft 30 on the bracket 10, ensuring the directional rotation of the roll on the rack 100, and better improving the printing accuracy of the processing system 1000.

[0046] The first limiting piece 51 can be a sliding plate structure slidably arranged on the bracket 11, and the first limiting piece 51 can be slid in a direction perpendicular to the axial direction of the bearing shaft 30 to switch between the pressing position and the release position; or the first limiting piece 51 can be a pressing plate structure rotatably arranged on the bracket 11, and the first limiting piece 51 can be rotated on one side of the mounting groove 113 to switch between the pressing position and the release position; of course, there are many ways for the first limiting piece 51 to move on the bracket 11, and the application does not limit the movement of the first limiting piece 51 on the bracket 11, as long as the first limiting piece 51 can press and release the bearing shaft 30.

[0047] Referring to Figure 4 In an embodiment of the present application, the rack 100 further comprises a second limiting piece 53, the second limiting piece 53 is arranged in the mounting groove 113 and located between the bearing shaft 30 and the bracket 10, and abuts against the opposite sides of the bearing shaft 30 with the bracket 10 respectively, and the first limiting piece 51 and the second limiting piece 53 abut against different sides of the bearing shaft 30 respectively.

[0048] In the embodiment, the rack 100 can further be provided with a second limiting piece 53 on the inner side wall of the mounting groove 113. The second limiting piece 53 is arranged between the bearing shaft 30 and the support 10. The second limiting piece 53 can clamp the bearing shaft 30 on the opposite sides in the axial direction. The bearing shaft 30 can be limited and assembled at the mounting groove 113. The axial movement of the bearing shaft 30 on the support 10 can be better limited. The directional rotation of the material roll 300 on the rack 100 can be ensured. The printing accuracy of the processing system 1000 can be better improved. The second limiting piece 53 is arranged on the inner side wall of the mounting groove 113. The second limiting piece 53 and the first limiting piece 51 can abut against different side walls of the bearing shaft 30.

The bearing shaft 30 can be limited and fixed in more degrees of freedom. The axial movement of the bearing shaft 30 on the support 10 can be better limited. The stable feeding of the material roll 300 can be ensured.

[0049] The second limiting piece 53 can be a silica gel piece, a rubber piece or other colloidal materials with certain elasticity. The second limiting piece 53 made of colloidal material can generate a certain elastic deformation when the bearing shaft 30 is inserted into the mounting groove 111 through the slot of the mounting groove 111. When the bearing shaft 30 is stably accommodated in the mounting groove 111, the elastic force of the second limiting piece 53 can act on the circumferential side of the bearing shaft 30. The second limiting piece 53 and the support can be clamped and installed on the bearing shaft. The bearing shaft 30 can be more conveniently installed on the support 10. The practicability and structural reliability of the rack 100 can be further improved.

[0050] Referring to Figure 3 and Figure 4 In one embodiment of the utility model, one end of the first limiting piece 51 is rotationally connected to the bracket 11 on one side of the mounting groove 113.

[0051] In the embodiment, the first limiting piece 51 can include a conversion seat 511 and a pressing rod 513.

The stable switching of the first limiting piece 51 between the pressing position and the release position can be realized. The structural stability and reliability of the rack 100 can be further improved.

[0052] The first limiting piece 51 can be better pressed into the mounting groove 113 when the first limiting piece 51 is rotated to the pressing position, so that the second limiting piece 53 in the mounting groove 113 can better press the bearing shaft 30 from another direction, the first limiting piece 51 and the second limiting piece 53 can more stably limit and press the bearing shaft 30, the fixed assembly of the bearing shaft 30 on the support is guaranteed, and the structural stability and reliability of the material rack 100 are further improved.

At this time, the inner wall of the open end of the first drum 3311 can be provided with an internal thread, and the outer periphery of the pressing structure 3313 can be provided with an external thread, so that the pressing structure 3313 can be connected and fixed with the inner wall thread of the first drum 3311; or, bolts or screws can be used to pass through the first drum 3311 and the pressing structure 3313 to achieve the connection and fixation of the first drum 3311 and the pressing structure 3313. There are many ways to connect the first drum 3311 and the pressing structure 3313, and this application does not limit this one, as long as a stable connection between the first drum 3311 and the pressing structure 3313 can be achieved.

[0057] Therefore, by connecting and installing the fastener 311 on the bearing shaft 30, using the first drum 3311 to sleeve the fastener 311, and using the pressing structure 3313 to extend into the inside of the first drum 3311 and clamp the fastener 311 with the inner wall of the first drum 3311, a more convenient assembly method for the first support member 331 on the bearing shaft 30 can be achieved. At the same time, the clamping structure 3313 and the first drum 3311 can be used to limit the position of the fastener 311, which is conducive to better improving the coaxiality of the installation of the first support member 331 and the fastener 311, ensuring the coaxial rotation of the first support member 331 on the bearing shaft 30, and further improving the stability and reliability of the material clamp assembly 33 driving the material roll 300 to rotate.
