However, the technical means claimed in the present application can be realized by various changes and modifications of the following embodiments.
Referring to fig. 1 and 2, some embodiments of the present application provide a printing cylinder comprising: a first fixing member 110, a second fixing member 120, a drum 130, a first gas leading-out mechanism 140, a first duct 150, and a second duct 160; the first fixing part 110 and the second fixing part 120 are oppositely arranged at two sides of the roller 130 along the axis of the roller 130; the drum 130 is rotatably disposed on the first fixing member 110 and the second fixing member 120 along a circumferential direction thereof, the drum 130 has a first chamber 131 and a second chamber 132 independent of each other, and the first chamber 131 and the second chamber 132 are both communicated with the outside of the drum 130 through an opening 133 disposed on a surface of the drum 130; the first gas leading-out mechanism 140 has a first outer casing 141, a first partition 142 and a second partition 143, the first outer casing 141 is disposed on the first fixing member 110 and is provided with a first opening 144 communicated with the inside thereof, the first partition 142 is disposed on the hole wall of the first opening 144 in a manner of rotating along the circumferential direction of the drum 130, the second partition 143 is disposed in the first outer casing 141 and divides the inside of the first outer casing 141 into a first space 145 between the first partition 142 and the second partition 143 and a second space 146 on the side of the second partition 143 away from the first partition 142, the first outer casing 141 is further provided with a first gas suction port 147 communicated with the first space 145 and a second gas suction port 148 communicated with the second space 146; one end of the first pipe 150 is communicated with the first chamber 131, and the other end thereof penetrates through the first partition 142 to be communicated with the first space 145; one end of the second pipe 160 is communicated with the second chamber 132, and the other end passes through the first partition 142 and then penetrates through the second partition 143 to be communicated with the second space 146.
Specifically, the shape of the first fixing element 110 and the second fixing element 120 is not limited in the present application, and the first fixing element 110 and the second fixing element 120 may be a plate, a plate-like object, a block, or the like. In one example, the first fixing element 110 and the second fixing element 120 are both plate-shaped objects or plate-like objects, in this case, the plate surface of the first fixing element 110 may be parallel to the plate surface of the second fixing element 120, and in addition, the plate surfaces of the first fixing element 110 and the second fixing element 120 may be perpendicular to the axis of the roller 130. When the first fixing element 110 and the second fixing element 120 are both plate-shaped objects, the first fixing element 110 and the second fixing element 120 may be metal plates made of metal with higher hardness, such as iron plates. When the first fixing element 110 and the second fixing element 120 are plate-like objects, the first fixing element 110 and the second fixing element 120 may be walls. Further, the positions of the first fixing member 110 and the second fixing member 120 are fixed, so that the stability of the printing cylinder during operation can be improved.
The present application does not limit the specific embodiment in which the drum 130 is rotatably disposed on the first fixing unit 110 and the second fixing unit 120 in the circumferential direction thereof. In one example, one end of the roller 130 is rotatably disposed on the first fixing member 110 through a bearing, and the other end of the roller 130 is rotatably disposed on the second fixing member 120 through a bearing. It should be noted that the present application is not limited to the specific embodiment of "rotation" mentioned below, and the desired rotation effect can be achieved by the bearing.
The first chamber 131 and the second chamber 132 are independent from each other, which means that there is no communication relationship between the first chamber 131 and the second chamber 132. The first chamber 131 and the second chamber 132 are both communicated with the outside of the drum 130 through the opening 133 provided on the surface of the drum 130 means that the first chamber 131 is communicated with the outside of the drum 130 through a part of the opening 133 provided on the surface of the drum 130, and the second chamber 132 is communicated with the outside of the drum 130 through another part of the opening 133 provided on the surface of the drum 130; specifically, the number of the openings 133 is plural, the plural openings 133 include a first type of opening and a second type of opening, the first chamber 131 communicates with the outside of the drum 130 through the first type of opening provided on the surface of the drum 130, and the second chamber 132 communicates with the outside of the drum 130 through the second type of opening provided on the surface of the drum 130. At this time, the paper adsorbed on the outer surface of the cylinder 130 at the opening 133 communicated with the first chamber 131 is that the paper adsorbed on the outer surface of the cylinder 130 at the first type opening; the sheet is attracted to the outer surface of the cylinder 130 at the opening 133 communicating with the second chamber 132, i.e., the sheet is attracted to the outer surface of the cylinder 130 at the second type of opening.
In some embodiments, the first chamber 131 and the second chamber 132 are sequentially disposed along the axis of the drum 130. At this time, "the opening 133 communicating with the first chamber 131" and "the opening 133 communicating with the second chamber 132" are also provided in order along the axis of the drum 130. Further, in combination with the above description of the embodiment, the first type openings and the second type openings are sequentially arranged along the axis of the drum 130. In this way, when two different sheets are simultaneously and respectively adsorbed by the first chamber 131 and the second chamber 132, the two different sheets are sequentially arranged on the surface of the cylinder 130 along the axis of the cylinder 130.
Alternatively, as shown in fig. 1 and 2, the first chamber 131 and the second chamber 132 are sequentially disposed along the circumference of the drum 130. At this time, "the opening 133 communicating with the first chamber 131" and "the opening 133 communicating with the second chamber 132" are also provided in this order in the circumferential direction of the drum 130. Further, in combination with the above description of the embodiment, that is, the first type openings and the second type openings are sequentially arranged along the circumferential direction of the drum 130. In this way, when two different sheets are simultaneously and respectively adsorbed by the first chamber 131 and the second chamber 132, the two different sheets are sequentially arranged on the surface of the cylinder 130 in the circumferential direction of the cylinder 130.
The specific location of the first gas guiding mechanism 140 on the first fixing member 110 is not limited in this application. In some embodiments, as shown in fig. 1, the first air guiding mechanism 140 is disposed on two sides of the first fixing member 110 opposite to the roller 130, so that the air suction device is connected to the first air suction opening 147 and the second air suction opening 148. Alternatively, the first gas guiding mechanism 140 and the cylinder 130 may be disposed on the same side of the first fixing member 110, and in this case, a part of the first gas guiding mechanism 140 may be disposed inside the cylinder 130 to reduce the space occupied by the printing cylinder.
In some embodiments, when the first partition 142 is rotatably disposed on the wall of the first hole 144 along the circumferential direction of the roller 130, the edge of the first partition 142 is in sealing connection with the wall of the first hole 144, so that gas leakage between the edge of the first partition 142 and the wall of the first hole 144 can be avoided. Preferably, the first partition 142 is a circular partition, the first opening 144 is a circular hole matched with the size of the first partition 142, and the first partition 142 and the roller 130 are coaxially disposed, so that the roller 130 can drive the first pipeline 150 and the first partition 142 to rotate along the circumferential direction of the roller 130 when rotating, and interference between the first pipeline 150 and other parts is avoided when the roller 130 rotates.
Preferably, the first partition 142 and the second partition 143 are sequentially arranged along the axis of the drum 130, and the axis of the portion of the first pipe 150 located at the first partition 142 is parallel to the axis of the drum 130. Thus, the first duct 150 and the first partition 142 are further facilitated to rotate along the circumferential direction of the drum 130 when the drum 130 rotates.
When the second partition 143 divides the interior of the first outer case 141 into the first space 145 and the second space 146, the first space 145 and the second space 146 are independent and not communicated with each other.
In one example, when the suction devices are connected to both the first suction port 147 and the second suction port 148, the number of suction devices can be two, and the two suction devices are connected to the first suction port 147 and the second suction port 148 respectively. In a further example, when the suction devices are connected to both the first suction port 147 and the second suction port 148, the number of suction devices may be one, and one suction device is connected to both the first suction port 147 and the second suction port 148, in which case, a valve disposed at the first suction port 147 and a valve disposed at the second suction port 148 may be further included, and in which case, when the first suction port 147 is not required, this may be achieved by closing the valve at the first suction port 147; and when the second suction opening 148 is not required, this can be achieved by closing a valve at the second suction opening 148.
In some embodiments, the portions of the second duct 160 located at the first barrier 142 and the second barrier 143 are coaxially disposed with the drum 130, and the portion of the second duct 160 located at the second barrier 143 is rotatably disposed on the second barrier 143 in a circumferential direction of the drum 130. In this way, when the drum 130 rotates, the second duct 160 may rotate together with the drum 130, so that a portion of the second duct 160 located at the second partition 143 rotates relative to the second partition 143, so as to prevent the second duct 160 from interfering with the second partition 143.
Alternatively, the second barrier 143 may be rotatably disposed in the first outer case 141 in the circumferential direction of the drum 130. Thus, when the roller 130 rotates, the roller 130 drives the second duct 160 and the second partition 143 to rotate along the circumference of the roller 130. Preferably, the second partition 143 is a circular partition, and the second partition 143 is disposed coaxially with the drum 130, so that the drum 130 can drive the second duct 160 and the second partition 143 to rotate along the circumferential direction of the drum 130 when rotating, so as to avoid interference between the second duct 160 and other parts when the drum 130 rotates.
It should be noted that, in some embodiments, in order to make the connectivity between the first pipe 150 and the first chamber 131 better, the first chamber 131 may also be communicated with a portion between two ends of the first pipe 150. Also, in order to make the communication between the second duct 160 and the second chamber 132 better, the second chamber 132 may also communicate with a portion between both ends of the second duct 160.
In some embodiments, the first conduit 150 is a linear conduit. The axis of the first duct 150 may be parallel to the drum 130 at any point.
The second duct 160 may also be a straight duct. The axis of the second conduit 160 at any point can now be made parallel or coincident with the drum 130 as desired.
In some embodiments, the print cylinder further comprises: a third conduit (not shown); the drum 130 has inside a third chamber (not shown) independent of the first chamber 131 and the second chamber 132, the third chamber communicating with the outside of the drum 130 through an opening 133 provided on the surface of the drum 130; the first air leading-out mechanism 140 further has a third partition plate (not shown in the figure), the first partition plate 142, the third partition plate and the second partition plate 143 are sequentially arranged along the axis of the drum 130, the third partition plate is located in the first outer casing 141 and divides the first space 145 into a third space between the third partition plate and the first partition plate 142 and a fourth space between the third partition plate and the second partition plate 143, the first outer casing 141 is further provided with a third air inlet (not shown in the figure) communicated with the fourth space, and the second air inlet 148 is communicated with the third space; the other end of the first pipe 150 communicates with the third space; the other end of the second pipe 160 penetrates through the first partition 142 and the third partition and then penetrates through the second partition 142 to communicate with the second space; one end of the third duct communicates with the third chamber, and the other end thereof communicates with the fourth space through the first partition 142 and the third partition 143, which is rotatably disposed in the first outer case 141 in the circumferential direction of the drum 130.
Thus, in the case of a printing cylinder having three chambers (i.e., the first chamber 131, the second chamber 132, and the third chamber) in the cylinder 130, the three chambers can be used simultaneously, and only any two or any one of the three chambers can be used, thereby making the printing cylinder more applicable. Meanwhile, the third partition plate is rotatably disposed in the first outer casing 141 along the circumferential direction of the drum 130, and when the drum 130 rotates, the third duct and the third partition plate are driven to rotate along the circumferential direction of the drum 130, so as to prevent the third duct from interfering with other components.
In this case, another duct, a chamber corresponding to the duct, and a partition plate provided in the first outer case 141 to partition the space may be provided. And will not be described in detail herein.
In some embodiments, the print cylinder further comprises: a fourth pipe (not shown), and a second gas leading-out mechanism (not shown); the drum 130 further has a fourth chamber (not shown) inside independent of the first chamber 131 and the second chamber 132, the fourth chamber communicating with the outside of the drum 130 through an opening 133 provided on the surface of the drum 130; the second gas leading-out mechanism has a second housing (not shown in the figure), a fourth suction port (not shown in the figure); one end of the fourth pipeline is communicated with the fourth cavity, and the other end of the fourth pipeline is communicated with the inside of the second outer shell through the second opening hole.
Thus, in the case of a printing cylinder with three chambers (i.e., the first chamber 131, the second chamber 132, and the fourth chamber) in the cylinder 130, the three chambers can be used simultaneously, and only any two or even any one of the three chambers can be used, so that the printing cylinder is applicable to more scenes.
It should be noted that this embodiment may also be combined with the third chamber and other structures mentioned in the above embodiments, so that the cylinder 130 in the printing cylinder has more chambers, and further, the applicable scenarios of this printing cylinder are more.
In some embodiments, the second gas leading-out mechanism further has a fourth partition plate (not shown), which is a circular partition plate and is disposed coaxially with the drum 130, and the fourth partition plate is rotatably disposed on the hole wall of the second opening along the circumferential direction thereof; the other end of the fourth pipeline passes through the fourth clapboard to be communicated with the inside of the second outer shell. Thus, when the roller 130 rotates, the fourth pipeline and the fourth partition plate can be driven to rotate together, so as to prevent the fourth pipeline from interfering with other parts.
Alternatively, the portion of the fourth pipe located at the second opening is coaxially disposed with the roller 130, and the portion of the fourth pipe located at the second opening is rotatably disposed on the hole wall of the second opening along the circumferential direction of the roller 130. Therefore, when the roller 130 rotates, the fourth pipeline can be driven to rotate at the second opening, so as to avoid the interference between the fourth pipeline and other parts.
It should be noted that, in this embodiment, a fifth pipeline may be further provided, and at this time, "the specific matching manner between the fourth pipeline and the fifth pipeline and the roller 130 and the second fixing element 120" may refer to "the specific matching manner between the first pipeline 150 and the second pipeline 160 and the roller 130 and the first fixing element 110", which is not described herein again.
