[0039] The medium channel roller assembly 100 includes a movable adjustment plate 110, a roller sleeve 120, a support shaft 130, a floating pressure spring 140 and a floating pressure roller 150; the movable adjustment plate 110 is connected to the channel body 210; the movable adjustment plate 110 is convexly provided with a plurality of limiting portions 111, the plurality of limiting portions 111 are arranged in sequence, and along the arrangement direction thereof, the protruding heights of the plurality of limiting portions 111 gradually decrease; the roller sleeve 120 is detachably connected to the movable adjustment plate 110, and the roller sleeve 120 is provided with a positioning portion 121 abutting against one of the limiting portions 111; the support shaft 130 is movably connected to the roller sleeve 120; the floating pressure roller 150 is connected to the support shaft 130, and the floating pressure spring 140 is sleeved on the support shaft 130, and abuts against the roller sleeve 120 and the floating pressure roller 150, so that the floating pressure roller 150 has a tendency to move toward the direction of the medium channel 211 of the channel body 210;

[0040] The channel body 210 is provided with a medium channel 211 and a movable pressure roller 212 movably connected to the channel body 210 ; the medium channel pressure roller assembly 100 is connected to the channel body 210 , and the floating pressure roller 150 is used to abut against the movable pressure roller 212 .

[0041] Please refer to Figure 1-Figure 4 The working principle of the medium channel roller assembly 100 in the medium channel structure 200 is:

[0042] First, the channel body 210 is provided with a medium channel 211 and a movable pressure roller 212 movably connected to the channel body 210, wherein the medium channel 211 is used to transmit consumables or medium, and the movable pressure roller 212 is movably connected to the channel body 210, and the movable pressure roller 212 is used to form the medium channel 211 together with the channel body 210, or to limit the height of the medium channel 211 in the channel body 210, and the movable pressure roller 212 is abutted against the floating pressure roller 150, so that during use, the position of the floating pressure roller 150 relative to the medium channel 211 can be adjusted, thereby adjusting the position of the movable pressure roller 212 relative to the medium channel 211, so as to adjust the height of the medium channel 211;

[0043] Specifically, during use, the positioning portion 121 on the roller sleeve 120 can be abutted against different limiting portions 111, thereby adjusting the positions of the support shaft 130, the floating compression spring 140 and the floating pressure roller 150 connected to the roller sleeve 120, thereby adjusting the position of the floating pressure roller 150 relative to the medium channel 211. In this way, based on the adjustment of the position of the floating pressure roller 150 relative to the medium channel 211, the abutting position of the movable pressure roller 212 forming the medium channel 211 can be adjusted by the floating pressure roller 150, so as to adjust the height of the medium channel 211 defined by the movable pressure roller 212. The height of the medium channel 211 can be adjusted to meet the passing requirements of consumables or media of different specifications, thereby reducing the cost of use and improving work efficiency.

[0044] It should be noted that the medium channel structure 200 is applied to a printing device or a scanning device, and during use, the medium channel structure 200 can be used to transport consumables or media, and this embodiment is described by taking the application of the medium channel structure 200 to a printing device as an example. Specifically, when the medium channel structure 200 is applied to a printing device, the printing device includes a printing component and the above-mentioned medium channel structure 200, and the printing component is connected to the medium channel structure 200.

[0045] For further information, please refer to Figure 1-Figure 4 As can be seen from the above, in this embodiment, the positioning portion 121 is made to abut against different limiting portions 111 to adjust the position of the roller sleeve 120, thereby adjusting the position of the floating roller 150; and in this embodiment, due to the structural setting of the floating pressure spring 140 and the movable connection between the support shaft 130 and the roller sleeve 120, when the floating roller 150 has a tendency to move toward the medium channel 211 of the channel body 210 under the action of the floating pressure spring 140, it can maintain the tendency to abut against the movable pressure roller 212 under the action of elasticity, thereby enabling the movable pressure roller 212 to maintain the state of abutting against the floating pressure roller 150. In addition, such a setting mode also enables the movable pressure roller 212 to squeeze the floating pressure roller 150 under the action of external force when processing ultra-high consumables or media, thereby compressing the floating pressure spring 140, thereby playing the role of giving way to avoid blockage or jamming.

[0046] Further, in the present embodiment, it can be known from the above content that, through the arrangement of the above-mentioned structure, the relative position of the roller sleeve 120 can be adjusted by adjusting the positioning portion 121 to abut against different limiting portions 111, thereby adjusting the height of the medium channel 211. Based on this, when configuring the limiting portion 111 and the positioning portion 121, the positioning portion 121 is a limiting tooth, and the limiting portion 111 is a toothed groove that cooperates with the limiting tooth. Through such an arrangement, its purpose is to improve the contact stability through the cooperation of the toothed surface, and to form a certain self-locking effect, thereby avoiding unintended displacement between the movable adjustment plate 110 and the roller sleeve 120.

[0047] On the basis of the above structure, in order to separate from the rolling sleeve 120 during the cooperation and movement of the support seat and the rolling sleeve 120, the medium channel roller assembly 100 further includes a stopper 160, which is connected to the support shaft 130 and is used to abut against the rolling sleeve 120 to limit the movement of the support shaft 130. The setting of the stopper 160 can limit the movement of the support shaft 130 relative to the rolling sleeve 120. In addition, the rolling sleeve 120 is provided with a stopper groove 124 connected to the movable hole 122, and the stopper 160 is accommodated in the stopper groove 124.

[0048] Please refer to Figure 1-Figure 5 In order to facilitate the assembly of the movable adjustment plate 110 and the roller sleeve 120, the roller sleeve 120 is provided with a movable hole 122 and a mounting hole 123; the medium channel roller assembly 100 also includes a connecting piece; the support shaft 130 is slidably connected to the movable hole 122; the connecting piece cooperates with the mounting hole 123 and is connected to the movable adjustment plate 110. In addition, it can be known from the above content that during use, when adjusting the height of the medium channel 211, the positioning portion 121 of the roller sleeve 120 is matched with different limiting portions 111, and the position of the roller sleeve 120 relative to the position of the channel body 210 remains unchanged. Therefore, in order to enable different limiting portions 111 on the movable adjustment plate 110 to match with the positioning portion 121, the movable adjustment plate 110 is configured with a strip hole 112, and the connecting member and the strip hole 112 can be slidably matched. As a result, the connecting member can slide to different positions relative to the strip hole 112, thereby enabling different limiting portions 111 on the movable adjustment plate 110 to correspond and match with the positioning portion 121.

[0049] Please refer to Figure 1-Figure 6Moreover, when adjusting the movable adjustment plate 110, the movable adjustment plate 110 slides relative to the channel body 210. Therefore, in order to guide the movement of the movable adjustment plate 110, the movable adjustment plate 110 is also configured with a guide portion 113, which extends along the arrangement direction of the plurality of limit portions 111 and is used for slidably cooperating with the channel body 210.

[0050] Based on the above content, in this embodiment, in order to improve the installation stability, a method is adopted in which the roller sleeve 120 is provided with two mounting holes 123, and the two mounting holes 123 are arranged at intervals, and the movable hole 122 is located between the two mounting holes 123; in addition, in order to enable the roller sleeve 120 to slide relative to the movable adjustment plate 110, thereby adjusting the position of the roller sleeve 120 relative to the movable adjustment plate 110, therefore, the length of the strip hole 112 is greater than the distance between the two mounting holes 123. The purpose of such a setting is to enable the connecting parts connected to the two mounting holes 123 to slide relative to the strip hole 112.

[0051] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
