Description

Technical Field

[0001] The present invention relates to the technical field of material conveying, and in particular to a circulating material storage device and printing equipment. Background Art

[0002] Printing devices print patterns on print media by jetting ink. Existing printing devices generally include a conveying device for transporting the print media. The conveying device sequentially transports the print media to various workstations for processing, such as printing and curing. Current conveying devices typically use an assembly line method to transport the print media, so that the print media is transported along the conveying direction of the conveying device. However, in some printing processes, a certain amount of time is required between two adjacent processes to allow the previous process to react sufficiently before the next process proceeds. Existing printing devices typically extend the length of the conveying device between the two workstations, allowing the print media to be transported over a certain distance to achieve a certain time interval between the two adjacent workstations. However, when the required interval is longer, the conveying device occupies a larger area, which increases the overall size of the device. Therefore, the conveying device in existing printing devices has the technical problem of being large in size. Summary of the Invention

[0009] Furthermore, the circulating storage device also includes a guiding mechanism; the guiding mechanism is used to guide the storage mechanism so that the storage mechanism moves back and forth between the first drive assembly and the second drive assembly.

[0010] Furthermore, the storage mechanism is slidingly connected to the first drive assembly; a slide groove is provided on the storage mechanism, and when the first drive assembly drives the storage mechanism until the slide groove corresponds to the guide mechanism, the first drive assembly drives the storage mechanism along the guide mechanism to the second drive assembly.

[0041] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. It should be noted that, in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. In the description of the present invention, it should be understood that the orientation or position relationship indicated by the terms "center", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like is based on the orientation or position relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the present invention. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further limitations, elements defined by the phrase "comprising..." do not preclude the presence of other identical elements in the process, method, article, or apparatus comprising the elements. The various features of the embodiments and examples of the present invention may be combined with each other if there is no conflict, and all are within the scope of protection of the present invention.

[0042] The following is combined with Figure 1 -Attached Figure 20 The present invention is described in further detail.

[0043] The embodiment of the present invention provides a circulating storage device, combined with Figure 1 as well as Figure 11 The structure includes: a storage mechanism 5, which is used to receive and cache materials; a circulation mechanism 4, which is transmission-connected to the storage mechanism 5; wherein the circulation mechanism 4 is used to drive the storage mechanism 5 to circulate between the feed end and the discharge end of the circulating storage device.

[0044] In this embodiment, the material is transferred to the storage mechanism 5, and the storage mechanism 5 circulates between the feeding end and the discharging end of the circulating storage device, so that the material is stored in the storage mechanism 5 on the circulation mechanism 4 for a certain period of time, and then the circulation mechanism 4 drives the storage mechanism 5 to the discharging end for storage; the cycle time of the circulation mechanism 4 can be adjusted according to the time required between the two workstations, and the storage mechanism 5 is driven to the discharging end so that the time for the material to pass between the two workstations meets the demand; since the storage mechanism 5 is provided to cache the material, the time requirement between the two workstations is met, and the length of the entire circulating storage device can be shortened at the same time; since the transmission device is provided with the storage mechanism 5 to cache the material, under the transmission device of the same length, the transmission time of the material is increased, thereby relatively reducing the volume of the circulating storage device, thereby reducing the footprint of the circulating storage device, and having the technical effect of improving the space utilization rate of the circulating storage device.

[0045] Specifically, the storage mechanism 5 stores materials along the thickness direction of the materials, so that the materials are stacked along their own thickness direction. In the same footprint, multiple materials can be stored, thereby reducing the volume of the transmission device occupied by the materials, thereby reducing the volume of the storage circulation structure; the circulation mechanism 4 can be set as a manipulator or the like to carry the storage mechanism 5, or the transmission path is a driving mechanism for the circulation loop. In this embodiment, the circulation mechanism 4 is selected as the driving mechanism for the circulation loop.

[0046] Preferably, the circulation mechanism 4 drives the storage mechanism 5 to reciprocate along a straight line to form a loop. Specifically, the bridge delivery device delivers materials to the storage mechanism 5 along the feeding direction, and the circulation mechanism 4 drives the storage mechanism 5 to rise to store materials in sequence. After the storage is full, the direction of the material conveying of the bridge delivery device is controlled to be opposite to the feeding direction for discharging; or a discharging mechanism 9 is set at the end of the other storage mechanism 5 away from the feeding end for discharging; at this time, the circulation mechanism 4 drives the storage mechanism 5 to descend for discharging, which has a simple structure, simple operation, and a small equipment footprint. It meets the transmission time requirement between the two workstations, reduces the length of the transmission device, and reduces the material consumption, thereby reducing the production cost.

[0047] The circulation path of the circulation mechanism 4 can also be a loop formed along a circular drive; specifically, a circular drive mechanism or multiple drive components are set up to alternately transmit the storage mechanism 5 in sequence, so that the storage mechanism 5 is transmitted along the circular loop; the driving mechanism of the circular loop is, for example, a circular drive mechanism, or multiple driving mechanisms are set up at the end to form a loop.

[0048] Preferably, the circulation mechanism 4 includes: a first drive assembly and a second drive assembly; the first drive assembly and the second drive assembly are alternately connected to the storage mechanism 5, and the transmission paths of the first drive assembly and the second drive assembly form a circulation loop.

[0049] In this embodiment, the first drive component corresponds to the feed end of the circulating storage mechanism 5, and the second drive component corresponds to the discharge end of the circulating storage mechanism 5; two drive components are set to make the circulating mechanism 4 form a circulating loop, which is convenient for setting a feeding mechanism at the feed end of the circulating storage mechanism 5 and setting a discharge mechanism 9 at the output end of the corresponding circulating storage mechanism 5. In this way, the feed end and the discharge end can feed and discharge without interfering with each other; the driving direction of the first drive component and the second drive component can be along a straight line or along a curve.

[0050] Preferably, the first drive component includes: a first conveying mechanism 41 and a second conveying mechanism 42; the output end of the first conveying mechanism 41 is arranged corresponding to the input end of the second conveying mechanism 42, the first conveying mechanism 41 and the second conveying mechanism 42 are alternately connected to the storage mechanism 5, the input end of the first conveying mechanism 41 is arranged corresponding to the output end of the second drive component, and the output end of the second conveying mechanism 42 is arranged corresponding to the input end of the second drive component.

[0051] In this embodiment, combined with Figure 13 The first conveying mechanism 41 can drive the accumulator 5 to rise and fall. The first conveying mechanism 41 drives the accumulator 5 to rise to store material. When the first conveying mechanism 41 drives the accumulator 5 to rise and collect the material, the accumulator 5 connects with the second conveying mechanism 42. At this time, the second conveying mechanism 42 drives the accumulator 5 to move to the input end of the second drive assembly. The accumulator 5 is now connected to the second drive assembly, forming a situation where the first conveying mechanism 41 stores material and the second conveying mechanism 42 transports material. The conveying directions of the first conveying mechanism 41 and the second conveying mechanism 42 are perpendicular to each other, making the structure of the entire circulation mechanism 4 simple and compact. The first drive assembly is configured as two drive components, which separates the storage and transport of material by the accumulator 5, facilitating control over the entire circulation of the accumulator 5.

[0052] Preferably, the second drive assembly includes: a third conveying mechanism 43 and a fourth conveying mechanism 44; the output end of the third conveying mechanism 43 is set corresponding to the output end of the fourth conveying mechanism 44, and the third conveying mechanism 43 and the fourth conveying mechanism 44 are alternately connected to the storage mechanism 5; the feed end of the third conveying mechanism 43 is set corresponding to the output end of the first drive assembly, and the output end of the fourth conveying mechanism 44 is set corresponding to the feed end of the first drive assembly.

[0053] In this embodiment, the second drive assembly has the same structure as the first drive assembly. Specifically, the third conveying mechanism 43 drives the accumulator 5 up and down, while the third conveying mechanism 43 drives the accumulator 5 down to discharge the material. When the third conveying mechanism 43 drives the accumulator 5 down to the end of the accumulator 5 and discharges the material, the accumulator 5 connects to the fourth conveying mechanism 44. At this point, the accumulator 5 connects to the first drive assembly, forming a loop where the third conveying mechanism 43 discharges the material and the fourth conveying mechanism 44 transfers the material. The conveying directions of the third conveying mechanism 43 and the fourth conveying mechanism 44 are perpendicular to each other, making the entire circulation mechanism 4 simple and compact. The second drive assembly is configured as two drive components, allowing the accumulator 5 to store and transfer the material separately, facilitating control over the entire circulation of the accumulator 5. In other embodiments, the first and second drive assemblies have the same structure, in which case the first and second drive assemblies are arranged end-to-end to form a loop.

[0054] Preferably, the first conveying mechanism 41 includes: a first driving member 411 and a mounting seat 412; the first driving member 411 is connected to the mounting seat 412, and the mounting seat 412 is detachably connected to the storage mechanism 5; the second conveying mechanism 42 includes: a second driving member 421 and a receiving seat 422; the second driving member 421 is connected to the receiving seat 422, and the receiving seat 422 is detachably connected to the storage mechanism 5.

[0055] In this embodiment, the structure of the third conveying mechanism 43 is consistent with that of the first conveying mechanism 41, and the structure of the fourth conveying mechanism 44 is consistent with that of the second driving mechanism. When the circulation mechanism 4 is working, the structure of the third conveying mechanism 43 is opposite to the conveying direction of the first conveying mechanism 41, and the structure of the fourth conveying mechanism 44 is opposite to the conveying direction of the second driving mechanism. The structures of the first conveying mechanism 41 and the second conveying mechanism 42 are described as follows. The first driving member 411 and the second driving member 421 are both configured in the form of a motor-driven screw rod, and the mounting seat 412 is detachably connected to the storage mechanism 5. When the first driving member 411 drives the storage mechanism 5 to the input end of the second conveying mechanism 42, the second driving member 421 drives the storage mechanism 5 to move. At this time, the matching relationship between the storage mechanism 5 and the mounting seat 412 is destroyed, so that the storage mechanism 5 is driven by the second driving member 421; after the second conveying mechanism 42 conveys the storage mechanism 5 to the second driving assembly, the receiving seat 422 of the second conveying mechanism 42 The coordination relationship with the accumulator 5 is broken. After the second drive assembly discharges the material, it returns the accumulator 5 to the first drive member 411, where it connects to the mounting base 412. This creates a system where the first and second conveying mechanisms 41, 42 are alternately connected to the accumulator 5. Since the structure of the third conveying mechanism 43 in this embodiment is identical to that of the first conveying mechanism 41, and the structure of the fourth conveying mechanism 44 is identical to that of the second drive assembly, the operating principle of the second drive assembly will not be elaborated here.

[0056] Preferably, the circulating storage device further comprises a guide mechanism 45 ; the guide mechanism 45 is used to guide the storage mechanism 5 along the axis so that the storage mechanism 5 moves back and forth between the first drive assembly and the second drive assembly.

[0057] In this embodiment, the guiding direction of the guide mechanism 45 is consistent with the transmission direction of the second conveying mechanism 42; the guide mechanism 45 can be bidirectional or unidirectional. When it is a unidirectional guide mechanism 45, the installation directions of the two guide mechanisms 45 are opposite. Two guide mechanisms 45 are provided. The second conveying mechanism 42 drives the storage mechanism 5 to move along one of the guide mechanisms 45 to the second drive assembly; the fourth conveying mechanism 44 drives the storage mechanism 5 to move along the other guide mechanism 45 to the first drive assembly. In this embodiment, the structure of the third conveying mechanism 43 is consistent with that of the first conveying mechanism 41, and the structure of the fourth conveying mechanism 44 is consistent with that of the second drive mechanism. Since this embodiment adopts the structure of the third conveying mechanism 43 consistent with that of the first conveying mechanism 41 and the structure of the fourth conveying mechanism 44 consistent with that of the second drive mechanism, the working principle of the second drive assembly will not be elaborated here.

[0058] Preferably, the storage mechanism 5 is slidingly connected to the first drive assembly; a slide groove is provided on the storage mechanism 5, and when the first drive assembly drives the storage mechanism 5 until the slide groove corresponds to the guide mechanism 45, the first drive assembly drives the storage mechanism 5 along the guide mechanism 45 to the second drive assembly.

[0059] In this embodiment, the guide mechanism 45 is configured as a guide rail, specifically, two arc-shaped parallel guide rails are configured. Specifically, a guide rail with the same size as the guide rail of the guide mechanism 45 is provided on the mounting seat 412 of the first conveying mechanism 41. When the first driving member 411 drives the storage mechanism 5 to rise and collect the full material, that is, the storage mechanism 5 is located at the input end of the second conveying mechanism 42, the two guide rails are docked with each other to form a track splicing. At this time, the second driving member 421 drives the storage mechanism 5 to move along the guide mechanism 45, so that the storage mechanism 5 is separated from the mounting seat 412, thereby transferring the storage mechanism 5; the slide groove on the storage mechanism 5 can cooperate with the guide rail of the guide mechanism 45, and can also cooperate with the guide rail of the mounting seat 412, so as to facilitate the transfer of the storage mechanism 5; the guide mechanism 45 can play a guiding role, and also can play a role of supporting the storage mechanism 5, thereby enabling the second driving member 421 to stably drive the storage mechanism 5.

[0060] Preferably, the circulating storage device also includes: a first bridge material delivery device and a second bridge material delivery device; the first bridge material delivery device is correspondingly arranged at the feed end of the circulation mechanism 4; the second bridge material delivery device is correspondingly arranged at the output end of the circulation mechanism 4; the storage mechanism 5 is provided with space for the first bridge material delivery device and the second bridge material delivery device to pass through.

[0061] In this embodiment, the first and second bridge transfer devices have the same structure, are installed in opposite directions, and are arranged in parallel. This reduces the volume of the entire circulating storage device used by the first and second bridge transfer devices. To further reduce the volume of the entire circulating storage device, the first and second bridge transfer devices are arranged side by side, shortening the distance between them. This further reduces the volume of the entire device.

[0062] Preferably, the circulating storage device includes at least two storage mechanisms 5; when one of the storage mechanisms 5 receives the material discharged by the first bridge material delivery device, the second bridge material delivery device discharges the material in the other storage mechanism 5.

[0063] In this embodiment, two storage mechanisms 5 are set to work alternately, which speeds up the transmission speed of the entire equipment. In other embodiments, multiple storage mechanisms 5 can also be set. When there are multiple storage mechanisms 5 as mentioned above, materials are loaded and then output in the second drive component in turn, which speeds up the working speed of the entire equipment.

[0064] Combine Figure 11 as well as Figure 12 The circulating storage device also includes: a locking mechanism 6, which is arranged between the first conveying mechanism 41 and the storage mechanism 5; when the locking mechanism 6 is in a locked state, the first conveying mechanism 41 conveys the storage mechanism 5; when the locking mechanism is in an open state, the first conveying mechanism 41 stops conveying the storage mechanism 5.

[0065] In this embodiment, a locking mechanism 6 is provided between the first conveying mechanism 41 and the storage mechanism 5. When the first conveying mechanism 41 conveys the storage mechanism 5, the locking mechanism 6 is in a locked state to fix the storage mechanism 5 and the first conveying mechanism 41. When the first conveying mechanism 41 stops conveying the storage mechanism 5, the locking mechanism 6 is in an open state, and then when the conveying of the storage mechanism 5 stops, the second conveying mechanism 42 transfers the storage mechanism 5. This embodiment facilitates fixing the storage mechanism 5 when conveying the storage mechanism 5 and facilitates the second conveying mechanism 42 to transfer the storage mechanism 5 when the conveying of the storage mechanism 5 stops, thereby solving the technical problem that the existing conveying device is not convenient for the conveying member 212 to convey the loading mechanism. It has the advantages of being convenient for conveying the storage mechanism 5 and for transferring the storage mechanism 5.

[0066] Specifically, the first conveying mechanism 41 and the second conveying mechanism 42 can be set independently of each other. In this case, the second conveying mechanism 42 is set at the output end of the first conveying mechanism 41, and the storage mechanism 5 is connected to the output end of the second conveying mechanism 42. The first conveying mechanism 41 drives the second conveying mechanism 42 to drive the storage mechanism 5 to move. When the first conveying mechanism 41 stops conveying, the second conveying mechanism 42 is started to drive the storage mechanism 5 to convey along the conveying direction of the second conveying mechanism 42, thereby realizing reversing transmission. The first conveying mechanism 41 and the second conveying mechanism 42 can also be set independently of each other. In this case, the input end of the second conveying mechanism 42 is corresponding to the output end of the first conveying mechanism 41. When the storage mechanism 5 is located at the output end of the first conveying mechanism 41, it is connected to the second conveying mechanism 42, so that the relative position of the second conveying mechanism 42 and the first conveying mechanism 41 is fixed, and thus there is no need to use the first conveying mechanism 41 to convey the second conveying mechanism 42, reducing the power of the first conveying mechanism 41 and at the same time reducing the movement path of the second conveying mechanism 42, that is, reducing the volume of the entire equipment and improving the space utilization rate of the entire alternating transmission device. In this embodiment, the first conveying mechanism 41 and the second conveying mechanism 42 are independently arranged, and the locking mechanism 6 is used to lock the storage mechanism 5 and the first conveying mechanism 41, so that the first conveying mechanism 41 and the storage mechanism 5 are locked along with the transmission of the first conveying mechanism 41. As the first conveying mechanism 41 stops, the locking mechanism 6 is opened to facilitate the transfer of the storage mechanism 5 by the second conveying mechanism 42. The structure is simple and compact, and it is easy to control the entire alternating transmission device.

[0067] Preferably, the locking mechanism 6 includes: a connector 61 and a socket 62; the connector 61 is plugged into the socket 62 to put the locking mechanism 6 in a locked state; when the second conveying mechanism 42 drives the storage mechanism 5, the connector 61 disengages from the socket 62 to destroy the locked state of the locking mechanism 6.

[0068] In this embodiment, the connector 61 and the socket 62 are disposed between the accumulator 5 and the first conveying mechanism 41. The connector 61 may be disposed in the accumulator 5 and the socket 62 in the first conveying mechanism 41, or vice versa. The socket 62 is provided with a through hole for the connector 61 to plug into. The connector 61 is cylindrical, with the through hole sized and shaped to match the outer contour of the connector 61. In other embodiments, the connector 61 may be of any shape, such as a cylinder. The axial direction of the connector 61 is perpendicular to the conveying direction of the first conveying mechanism 41, meaning that the connector 61 is inserted into the through hole along its axial direction. In this embodiment, the conveying direction of the first conveying mechanism 41 is vertical, driving the accumulator 5 upward and downward. The axial direction of the connector 61 is parallel to the conveying direction of the second conveying mechanism 42. When the second conveying mechanism 42 drives the accumulator 5 toward or away from the first conveying mechanism 41, the connector 61 engages with or disengages from the socket 62, thereby locking or unlocking the locking mechanism 6. The axial direction of the connector 61 is perpendicular to the conveying direction of the first conveying mechanism 41 , which limits the displacement of the first conveying mechanism 41 of the storage mechanism 5 in the conveying direction, thereby fixing the first conveying mechanism 41 of the storage mechanism 5 .

[0069] Preferably, the locking mechanism 6 further includes a limiting member 63 ; the limiting member 63 engages with the connector 61 to limit the relative position of the connector 61 and the socket 62 .

[0070] In this embodiment, the limiting member 63 is arranged on the outside of the socket 62, and is engaged with the outer wall of the plug-in connector 61 to limit the relative position of the limiting member 63 in the socket 62. Specifically, the limiting direction of the limiting member 63 is perpendicular to the axial direction of the plug-in connector 61, thereby limiting the plug-in connector 61 from being separated from the socket 62, further fixing the plug-in connector 61 to the socket 62, and thus fixing the storage mechanism 5 to the first conveying mechanism 41. In other embodiments, the limiting member 63 may be arranged inside the socket 62. In this case, one end of the limiting member 63 extends toward the axis of the socket to engage with the inside of the plug-in connector 61. Multiple limiting members 63 may be provided to cooperate with each other to engage the plug-in connector 61. Elastic components such as springs may also be provided between the limiting member 63 and the socket 62 to make the limiting member 63 elastic.

[0071] Preferably, the limiting member 63 is rotatably connected to the socket 62 , and a rotation space for the limiting member 63 to rotate is provided on the socket 62 ; after the connector 61 is plugged into the socket 62 , a portion of the rotation space is exposed.

[0072] In this embodiment, after the limiting member 63 is inserted into the socket 62, the limiting member 63 rotates into the rotation space and engages with the plug-in connector 61 that has escaped the rotation space, thereby limiting the movement of the plug-in connector 61 in the direction of its own axis, thereby forming a fixed connection between the storage mechanism 5 and the first conveying mechanism 41. Specifically, the limiting member 63 has a latching tooth on the side facing the plug-in connector 61, and the plug-in connector 61 has a corresponding latching hole. The latching tooth and the latching hole are adapted to engage with each other, so that the limiting member 63 is engaged with the plug-in connector 61. When the limiting member 63 is engaged with the plug-in connector 61, the limiting member 63 is located within the rotation space, making the entire locking mechanism 6 compact and ingenious, and thus making the entire alternating transmission device more compact.

[0073] Preferably, the locking mechanism 6 further includes a reset member; the reset member provides a reset force for the limiting member 63 toward the plug-in member 61 .

[0074] In this embodiment, when the connector 61 is plugged into the socket 62, the reset member provides a reset force to the connector 61, so that the limiter 63 always maintains a downward force and engages with the connector 61. When the limiter 63 is opened, the reset member provides a reset force to the limiter 63, so that the limiter 63 is reset, thereby preventing the limiter 63 from opening and closing excessively and affecting the next position of the connector 61. The reset member can be configured as an elastic member or an elastic member with a tensile force.

[0075] Preferably, the reset member is provided on the socket 62 , and the reset member is located on the side of the rotation axis of the limiting member 63 away from the plug-in member 61 .

[0076] In this embodiment, the reset member is configured as an elastic component with elasticity, preferably a spring; the limiting member 63 is provided with a protrusion extending toward the reset member, and the protrusion is provided on the reset member to facilitate the reset of the limiting member 63. The reset member is provided on the socket 62, thereby making the entire locking mechanism 6 compact.

[0077] Preferably, the socket 62 is provided on the first conveying mechanism 41 , and the connector 61 is provided on the storage mechanism 5 .

[0078] In this embodiment, the first conveying mechanism 41 includes a first driving member 411 and a mounting base 412. The socket 62 is disposed on the mounting base 412 and moves as the first driving mechanism drives the mounting base 412. The connector 61 is disposed on the storage mechanism 5 to facilitate the removal of the connector 61 from the socket 62. The connector 61 is smaller than the socket 62. The connector 61 is disposed on the storage mechanism 5. When the second conveying mechanism 42 conveys the storage mechanism 5, the smaller connector 61 minimizes interference with other components, thereby facilitating the transport of the connector 61.

[0079] Preferably, the alternating transmission device also includes: an opening member 64; the first conveying mechanism 41 includes a fixed part and a transmission part; the transmission part is used to install the storage mechanism 5, and the opening member 64 is arranged on the fixed part; the transmission part drives the storage mechanism 5 to move relative to the opening member 64, so that the limiting member 63 is hindered by the opening member 64 and rotates, thereby destroying the locking relationship between the limiting member 63 and the connector 61.

[0080] In this embodiment, the mounting base 412 (see Figure 13 ) i.e., the transmission portion; an opening member 64 is provided, and the opening member 64 is fixed in a position on the first conveying mechanism 41, i.e., the locking mechanism moves relative to the opening member 64. When the opening member 64 contacts the limiting member 63, the mounting seat 412 continues to move upward. At this time, the limiting member 63 is restricted by the opening member 64 and receives a downward force, which causes the limiting member 63 to rotate, thereby breaking the engagement relationship between the limiting member 63 and the plug-in member 61. At this time, the second conveying mechanism 42 drives the storage mechanism 5 to move, causing the plug-in member 61 to disengage from the socket 62. The opening member 64 is provided to automatically open the limiting member 63, thereby facilitating the transfer of the storage mechanism 5.

[0081] Combine Figure 11 as well as Figure 17 The circulating storage device also includes: a latch mechanism 7, which is arranged between the second conveying mechanism 42 and the storage mechanism 5; when the storage mechanism 5 is located at the output end of the first conveying mechanism 41, the latch mechanism 7 forms a locking state to enable the second conveying mechanism 42 to be transmission-connected with the storage mechanism 5.

[0082] In this embodiment, the output end of the first conveying mechanism 41 is corresponding to the output end of the second conveying mechanism 42. When the first conveying mechanism 41 conveys the storage mechanism 5 to the output end, the storage mechanism 5 is located at the input end of the second conveying mechanism 42. At this time, the latch mechanism 7 forms a locked state, connecting the storage mechanism 5 and the second conveying mechanism 42. Starting the second conveying mechanism 42 can transfer the storage mechanism 5 along the conveying direction of the second conveying mechanism 42, so that when the storage mechanism 5 is transmitted along the first conveying mechanism 13, the storage mechanism 5 is not connected to the second conveying mechanism 42. When the storage mechanism 5 needs to be transferred, the latch mechanism 7 connects the storage mechanism 5 and the second conveying mechanism 42, thereby realizing the transfer of the storage mechanism 5, solving the technical problem that the existing transmission device is not convenient for the conveying member 212 to transport the loading mechanism; it has the advantages of being convenient for conveying the storage mechanism 5 and convenient for transferring the storage mechanism 5.

[0083] Specifically, the first conveying mechanism 41 and the second conveying mechanism 42 can be set independently of each other. In this case, the second conveying mechanism 42 is set at the output end of the first conveying mechanism 41, and the storage mechanism 5 is connected to the output end of the second conveying mechanism 42. The first conveying mechanism 41 drives the second conveying mechanism 42 to drive the storage mechanism 5 to move. When the first conveying mechanism 41 stops conveying, the second conveying mechanism 42 is started to drive the storage mechanism 5 to convey along the conveying direction of the second conveying mechanism 42, thereby realizing reversing transmission. The first conveying mechanism 41 and the second conveying mechanism 42 can also be set independently of each other. In this case, the input end of the second conveying mechanism 42 is corresponding to the output end of the first conveying mechanism 41. When the storage mechanism 5 is located at the output end of the first conveying mechanism 41, it is connected to the second conveying mechanism 42, so that the relative position of the second conveying mechanism 42 and the first conveying mechanism 41 is fixed, and thus there is no need to use the first conveying mechanism 41 to convey the second conveying mechanism 42, reducing the power of the first conveying mechanism 41 and at the same time reducing the movement path of the second conveying mechanism 42, that is, reducing the volume of the entire equipment and improving the space utilization rate of the entire alternating transmission device. In this embodiment, the first conveying mechanism 41 and the second conveying mechanism 42 are independently arranged, and the locking mechanism 6 is used to lock the storage mechanism 5 and the first conveying mechanism 41, so that the first conveying mechanism 41 and the storage mechanism 5 are locked along with the transmission of the first conveying mechanism 41. As the first conveying mechanism 41 stops, the locking mechanism 6 is opened to facilitate the transfer of the storage mechanism 5 by the second conveying mechanism 42. The structure is simple and compact, and it is easy to control the entire alternating transmission device.

[0084] Specifically, the first conveying mechanism 41 and the second conveying mechanism 42 are independently arranged, and the locking mechanism 6 is used to lock the storage mechanism 5 and the first conveying mechanism 41, so that the first conveying mechanism 41 and the storage mechanism 5 are locked along with the transmission of the first conveying mechanism 41. As the first conveying mechanism 41 stops, the locking mechanism 6 is opened to facilitate the second conveying mechanism 42 to transfer the storage mechanism 5. The structure is simple and compact, and it is easy to control the entire alternating transmission device.

[0085] Preferably, the latch mechanism 7 includes: a latch 71 and a slot component 72; the latch 71 is inserted into the slot component 72 to put the latch mechanism 7 in a locked state; when the first conveying mechanism 41 drives the storage mechanism 5, the latch 71 disengages from the slot component 72 to destroy the locked state of the latch mechanism 7.

[0086] In this embodiment, the latch mechanism 7 is disposed between the second conveying mechanism 42 and the accumulator mechanism 5. Specifically, the slot component 72 can be disposed on the accumulator mechanism 5, and the latch 71 can be disposed on the second conveying mechanism 42, or vice versa. The slot component 72 is provided with a slot that matches the latch 71. The latch 71 is inserted into the slot component 72 to connect the accumulator mechanism 5 to the second conveying mechanism 42. When the second conveying mechanism 42 conveys the accumulator mechanism 5 toward the first conveying mechanism 41, the accumulator mechanism 5 is connected to the first conveying mechanism 41. When the first conveying mechanism 41 drives the accumulator mechanism 5, the latch 71 disengages from the slot component 72, thereby breaking the locked state of the locking mechanism 6.

[0087] Specifically, the axial direction of the pin 71 is perpendicular to the conveying direction of the second conveying mechanism 42 and parallel to the conveying direction of the first conveying assembly 21; the pin 71 limits the movement of the storage mechanism 5 relative to the second conveying mechanism 42 in the conveying direction of the second conveying mechanism 42, thereby preventing the storage mechanism 5 from detaching from the second conveying mechanism 42 due to inertia when the second conveying mechanism 42 conveys the storage mechanism 5; at the same time, it is parallel to the conveying direction of the first conveying assembly 21, which facilitates the direct connection of the pin 71 from the first conveying mechanism 41 to the slot component 72, and also facilitates the first conveying mechanism 41 to transfer the storage mechanism 5.

[0088] Preferably, the latch mechanism 7 further includes a fastener 73 ; the fastener 73 abuts against the outer wall of the latch 71 to limit the relative position of the latch 71 and the slot component 72 .

[0089] In this embodiment, the fastener 73 can be set inside the slot component 72 or outside the slot component 72. It is preferably set inside the slot to cooperate with the slot component 72 to fix the pin 71 in the slot component 72, thereby preventing the pin 71 from detaching from the slot component 72 when the second conveying mechanism 42 transfers the storage mechanism 5, thereby causing the storage mechanism 5 to fall off.

[0090] Preferably, the slot component 72 includes: a slot for inserting the pin 71 ; and a fastener 73 disposed on an inner wall of the slot and extending toward the axis of the slot component 72 .

[0091] In this embodiment, the size of the slot is adapted to the outer diameter of the slot, a plurality of fasteners 73 are provided, all of which are passed through the slot and extend toward the axis of the slot component 72 ; all of the fasteners 73 cooperate with each other to fix the pin 71 .

[0092] Preferably, the end of the fastener 73 facing the axis of the slot component 72 is configured to be arc-shaped.

[0093] In this embodiment, the latch pin 71 is inserted into the slot along the arc portion of the fastener 73 , which facilitates the insertion of the latch pin 71 into the slot component 72 .

[0094] Preferably, the latch mechanism 7 further includes an elastic member (not shown in the figure); the elastic member is disposed between the fastener 73 and the slot component 72 , and the elastic member provides elastic force for the fastener 73 .

[0095] In this embodiment, the elastic member is configured as a spring, and the elastic member is disposed at one end of the fastener 73 away from the axis of the slot component 72. When the pin 71 is inserted into the slot component 72, the fastener 73 is squeezed by the pin 71, and the elastic member is compressed. The compressed elastic member returns to its original shape to apply elastic force to the fastener 73, pressing the pin 71 tightly against the slot component 72.

[0096] Preferably, the second conveying mechanism 42 drives the storage mechanism 5 to move along the guide mechanism 45 .

[0097] In this embodiment, a conveying mechanism 13 includes a first driving member 411 and a mounting base 412. The guiding direction of the guide mechanism 45 is consistent with the transmission direction of the second conveying mechanism 42. The guide mechanism 45 can be bidirectional or unidirectional. The guide mechanism 45 is provided to facilitate the transfer of the accumulator 5. The guide mechanism 45 not only guides but also supports the accumulator 5, preventing the latch 71 from being disengaged from the slot member 72 due to the weight of the accumulator 5 during transfer, thereby enabling the second driving member 421 to securely drive the accumulator 5.

[0098] Preferably, the first conveying mechanism 41 includes a fixing part and a transmission part; the storage mechanism 5 is slidably arranged on the transmission part; a slide groove is provided on the storage mechanism 5, and when the first conveying mechanism 41 drives the storage mechanism 5 to move until the slide groove corresponds to the guide mechanism 45, the second conveying mechanism 42 drives the storage mechanism 5 along the guide mechanism 45 to the second driving assembly.

[0099] In this embodiment, the mounting seat 412 is the transmission part, which can move with the drive of the first driving member 411, and the guide mechanism 45 is set as a guide rail, specifically two arc-shaped parallel guide rails are set, and specifically, a guide rail with a size consistent with the guide rail of the guide mechanism 45 is set on the mounting seat 412 of the first conveying mechanism 41. When the first driving member 411 drives the storage mechanism 5 to rise and collect full materials, that is, the storage mechanism 5 is located at the input end of the second conveying mechanism 42, the two guide rails are docked with each other to form a track splicing, and the second driving member 421 drives the storage mechanism 5 to move along the guide mechanism 45, so that the storage mechanism 5 is separated from the mounting seat 412, thereby transferring the storage mechanism 5; the slide groove on the storage mechanism 5 can cooperate with the guide rail of the guide mechanism 45, and can also cooperate with the guide rail of the mounting seat 412, so as to facilitate the transfer of the storage mechanism 5.

[0100] Preferred as Figure 1As shown, the printing device includes at least two circulating material storage devices, the number of the circulating material storage devices is even, and the output end of the upstream circulating material storage device is corresponding to the feed end of the downstream circulating material storage device.

[0101] In this embodiment, two circulating storage devices are provided. The output of the previous circulating storage device serves as the second bridge material transfer device 32, which also serves as the feed port for the next circulating storage device. When multiple circulating storage devices are provided, the output of the previous circulating storage device serves as the feed port for the next circulating storage device, thus connecting the multiple circulating storage devices. Setting the number of circulating storage devices to an even number ensures that all materials form a cycle after the first and second circulating storage devices are exchanged. This ensures that the time intervals between each material flowing through each process are as equal as possible, thereby ensuring the transmission efficiency of each material. Providing multiple circulating storage devices allows for a longer material buffering period.

[0102] Combine Figure 14-16 The above-mentioned storage mechanism 5 includes: a storage mechanism body, the storage box is in a frame shape; a storage portion 52, the storage portion 52 is arranged between the opposite sides of the storage mechanism body; a tightening portion 53, the tightening portion 53 is arranged on the storage portion 52, and the tightening portion 53 is used to tighten the material.

[0103] In this embodiment, the storage portion 52 is used to place materials. Since a pressing portion 53 is provided on the storage portion 52, the pressing portion 53 presses the materials tightly. After the materials are placed on the storage portion 52, the pressing portion 53 presses the materials tightly. When an external force is applied, the pressing portion 53 limits the movement of the materials, thereby avoiding the displacement of the materials due to the external force, and solving the technical problem that when the existing storage mechanism 5 stores materials, the materials are easily displaced by external forces. The storage mechanism body is provided with a pressing portion 53 to press the materials tightly, which has the advantage of being convenient for storing materials.

[0104] Specifically, the storage mechanism body includes a bottom plate 511, an upper plate 512, a back plate 513, and two side plates 514 arranged between the bottom plate 511 and the upper plate 512. A plurality of storage portions 52 are arranged on the two side plates 514 of the storage mechanism body. Each storage portion 52 is parallel to each other and spaced apart along the thickness direction of the storage portion 52. A space for accommodating materials is formed between each storage portion 52. Each storage portion 52 is provided with a pressing portion 53, which can be oriented toward the bottom plate 511 or toward the upper plate 512. When the pressing portion is oriented toward the bottom plate 511, each pressing portion cooperates with the adjacent lower storage portion 52 to press the material. When the pressing portion is oriented toward the upper plate 512, each pressing portion cooperates with the adjacent upper storage portion 52 to press the material. In this embodiment, the pressing portion is arranged toward the bottom plate 511, that is, the pressing portion is arranged on the storage portion 52 and extends toward the bottom plate 511. Multiple abutment portions are provided along the sides of the storage portion 52 near the side panels 514, and abutment portions are provided on both sides of the storage portion 52 near the side panels 514. This ensures that after the material enters the storage portion 52, both sides of the material in the longitudinal direction are subjected to the abutment force of the abutment portions 53. The abutment portions 53 can be fixed or movably provided on the storage portion 52.

[0105] Preferably, the pressing portion 53 is movably disposed on the storage portion 52 .

[0106] In this embodiment, the pressing portion 53 is movably connected to the storage portion 52. When the material enters the storage portion 52, the pressing portion 53 is squeezed by the material, causing the pressing portion 53 to move away from the material. When the material fits the pressing portion 53 and the pressing portion 53 is no longer squeezed by the material, the pressing portion 53 stops moving, thereby allowing the storage mechanism 5 to adapt to materials of different thicknesses, thereby improving the practicality of the storage mechanism 5. Specifically, when the pressing portion 53 extends toward the upper plate 512, an elastic component can be provided between the pressing portion 53 and the storage portion 52. When the pressing portion 53 is squeezed by the material, the pressing portion 53 is compressed by the elastic component, causing the pressing portion 53 to move downward. After the pressing portion 53 is no longer squeezed by the material and moves downward, the elastic component provides elastic force to provide a pressing force for the pressing portion 53, thereby pressing the material. The elastic component can be provided as a spring or elastic gasket or other elastic material. When the pressing portion 53 extends toward the bottom plate 511, it can be movably disposed within the storage portion 52. When pressed by the material, the pressing portion 53 moves upward. After the material is transferred to the storage portion 52, the pressing portion 53 exerts a pressing force on the material due to its own gravity, thereby clamping the material. To facilitate the movement of the pressing portion 53, a guide member can be provided between the pressing portion 53 and the storage portion 52. The guide member can be in the form of a rod and pass through the storage portion 52, allowing the pressing portion 53 to move along the guide member. Furthermore, to facilitate the return of the pressing portion 53, an elastic member such as a spring can be passed through the guide rod 142 to provide a restoring force to the pressing portion 53, thereby clamping the material.

[0107] Preferably, the pressing portion 53 is movably disposed inside the storage portion 52 , and the pressing portion 53 extends downward toward the storage portion 52 .

[0108] In this embodiment, when the pressing portion 53 extends toward the bottom plate 511, the pressing portion 53 can be movably disposed on the storage portion 52. When the pressing portion 53 is squeezed by the material, it moves upward. At this time, after the material is transferred to the storage portion 52, the pressing portion 53 provides a pressing force to the material due to its own gravity, thereby pressing the material. The pressing portion 53 is pressed downward by its own gravity to press the material, eliminating the need for a reset component to provide elastic force to press the material. The structure is simple and easy to operate, while also facilitating the entry of the material between the pressing portion 53 and the storage portion 52. Specifically, the pressing portion 53 can be disposed on the surface of the storage portion 52, or it can be partially disposed within the storage portion 52, so that the pressing portion 53 partially protrudes from the storage portion 52.

[0109] Preferably, a cavity for accommodating the pressing portion 53 is provided inside the storage portion 52 , and the pressing portion 53 at least partially passes through the storage portion 52 and moves toward the bottom of the storage portion 52 .

[0110] In this embodiment, the abutting portion 53 is partially disposed within the storage portion 52, i.e., the abutting portion 53 at least partially overlaps the storage portion 52. The interior of the storage portion 52 provides space for the abutting portion 53 to move, thereby reducing the volume of the entire storage mechanism 5 and making the structure of the entire storage mechanism 5 more compact. Of course, in other embodiments, the abutting portion 53 may also be disposed on one side of the storage portion 52, so that the entire abutting portion 53 is located on one side of the storage portion 52.

[0111] Preferably, two rows of the pressing portions 53 are provided, and the two rows of the pressing portions 53 are respectively provided on both sides corresponding to the material conveying direction.

[0112] After the material enters the material storage mechanism body, the pressing portion 53 presses against both sides of the material, thereby making the force on the material balanced and facilitating pressing the material.

[0113] Preferably, a plurality of storage portions 52 are provided, and all storage portions 52 are arranged on the storage mechanism body at intervals along the thickness direction thereof.

[0114] In this embodiment, a plurality of storage portions 52 are provided, which can buffer a plurality of materials at a time, and are spaced apart along the thickness direction, making the entire storage mechanism structure more compact.

[0115] Preferably, a wedge-shaped portion 522 is provided at the opening of the pressing portion 53 toward the storage mechanism body, so that an angle toward the opening of the storage mechanism body is formed between the pressing portion 53 and the storage portion 52; thereby, when the material enters between the pressing portion 53 and the storage portion 52, an extrusion force is provided to the pressing portion 53 along the wedge-shaped portion 522 of the pressing portion 53, so that the pressing portion 53 is gradually subjected to the extrusion force of the material, which facilitates the pressing portion 53 to be subjected to force, and then facilitates the pressing portion 53 to move relative to the storage portion 52, and then facilitates the material to enter between the storage portion 52 and the pressing portion 53.

[0116] Preferably, the storage mechanism 5 further includes a limiting portion 54 , which is used to limit the movement of the pressing portion 53 .

[0117] In this embodiment, a stopper 54 is provided at the upper end of the cavity to prevent the abutting portion 53 from being dislodged from the cavity due to external forces. The stopper 54 can be a solid plate-like structure or a hollow annular plate-like structure. During the manufacturing process of the storage box, the stopper 54 is placed in the cavity and fixed to the inner wall of the upper end of the cavity through an interference fit. After the stopper 54 is installed in the cavity, a movable space is formed between the cavity and the stopper 54 for the stopper 54 to move.

[0118] Preferably, the pressing portion 53 is spherical.

[0119] In this embodiment, a circular opening is provided in the cavity toward the bottom plate 511, and the pressing portion 53 passes through the storage portion 52 from the circular opening. When the pressing portion 53 is affected by its own gravity, it can be stuck at the opening, and when squeezed by the material, it can be separated from the opening. When it falls due to its own gravity, it can still fall accurately into the opening, so that part of it extends toward the opening to press the material. The pressing portion 53 is set to be spherical, and the outer wall of the spherical pressing portion 53 is rounded, which is convenient for movement due to extrusion, and can be reset in place after the cavity moves, so as to facilitate the contact with the material; in addition, the outer side of the pressing portion is circular, and an open opening facing the opening of the storage box is formed between its outer side and the storage portion 52, which is equivalent to forming a guide opening on the outer side of the pressing portion 53. When the material enters between the pressing portion 53 and the storage portion 52, the pressing portion 53 is provided with an extrusion force along the outer side of the pressing portion 53, so that the pressing portion 53 is gradually subjected to the extrusion force of the material, which is convenient for the pressing portion 53 to be subjected to force, and then the pressing portion 53 is convenient for the movement of the pressing portion 53 relative to the storage portion 52, and then the material is convenient for entering between the storage portion 52 and the pressing portion 53.

[0120] Preferably, a wedge-shaped portion 522 is provided at the opening of the storage portion 52 corresponding to the storage mechanism body.

[0121] In this embodiment, the wedge-shaped portion 522 is located on the side facing the bottom plate 511. The wedge-shaped portion 522 of the storage portion 52 and the adjacent downwardly facing storage portion 52 form an angle that opens toward the opening of the storage mechanism body. This angle guides the material, thereby facilitating the material to enter the storage portion 52. In other embodiments, the wedge-shaped portion 522 can be located on the side of the storage portion 52 facing the upper plate 512.

[0122] Preferably, the material storage mechanism 5 is used to receive the materials output by the transmission mechanism, and the material storage mechanism 5 is provided with a space for the transmission mechanism to pass through.

[0123] In this embodiment, space for the transmission mechanism to pass through is set at the corresponding positions of the bottom plate 511, the upper plate 512 and the storage portion 52, which facilitates the engagement of the transmission mechanism with the storage mechanism 5, and further facilitates the transmission mechanism to transmit the material to the storage portion 52.

[0124] Preferably, a plurality of weight-reducing holes 515 are provided on the main body of the storage mechanism.

[0125] In this embodiment, a plurality of weight-reducing holes 515 are provided on the upper plate 512 and the side plate 514 of the material storage mechanism body to reduce the weight of the material storage mechanism body and facilitate driving the material storage box mechanism.

[0126] Preferably, the storage portion 52 is detachably arranged on two opposite inner sides of the storage mechanism body.

[0127] In this embodiment, the storage portion 52 is configured to be removable, and the relative position between the storage portion 52 and the storage mechanism body can be adjusted according to the height of the material, thereby making the storage mechanism body adaptable to materials of different thicknesses. The storage portion 52 is removably mounted to the storage mechanism body by screws, and the storage mechanism body is provided with mounting holes corresponding to the screws, so that the surface of the screws is flush with the surface of the storage mechanism body, thereby making the entire storage mechanism 5 more neatly processed and compact.

[0128] Preferably, the side panels 514 of the storage mechanism body are each provided with a connector 61 on the side away from each other, and the upper plate 512 and the bottom plate 513 are each provided with a slot component 72 on the side away from each other. The storage mechanism 5 can be connected to the first conveying mechanism 41 and the third conveying mechanism 43 on the left and right sides respectively; and can form a transmission connection with the second conveying mechanism 42 and the fourth conveying mechanism 44 on the upper and lower sides respectively.

[0129] Combine Figure 1 as well as Figure 10As shown, the above-mentioned first bridge material delivery device 31 and the second bridge material delivery device are collectively referred to as the bridge material delivery device, which includes: a transmission mechanism body 33 and a porous transmission belt 34; the transmission belt 34 is arranged around the outside of the conveying mechanism 13 body and rotates around the transmission mechanism body 33; a cavity is provided inside the transmission mechanism body 33, and a switching element is provided in the cavity, which is connected to the positive pressure system and the first negative pressure system respectively, and the cavity is connected to the first negative pressure system or the positive pressure system through the switching element.

[0130] In this embodiment, the upper end surface of the conveyor belt 34 is used to carry and convey materials. When material needs to be conveyed, the switch element is activated, connecting the switch element to the first negative pressure system, forming a negative pressure area inside the cavity, acting on the material, and realizing negative pressure material transmission, which facilitates the transmission of lighter materials. When material discharge is required, the switch element is switched, thereby connecting the positive pressure system to the cavity, instantly connecting the positive pressure system to the cavity, and quickly filling the cavity with positive pressure, facilitating the discharge of the material. Since the cavity is connected to the positive pressure system and the first negative pressure system through the switch element, the pressure in the cavity can be switched between positive and negative pressure at any time by simply switching the switch element according to the needs of discharging or conveying materials. Therefore, when conveying heavy materials and passing them to the next device, the positive pressure is activated to discharge the materials, thereby facilitating the delivery of materials. This solves the technical problem of existing negative pressure transmission mechanisms that are simply inconvenient for material transmission and has the advantage of facilitating material transmission.

[0131] In this embodiment, if Figure 20 As shown, the bridge material delivery device is provided with three transmission mechanism bodies 33, and the cavities between the three transmission mechanism bodies 33 share the same negative pressure system and the same positive pressure system; specifically, the bridge material delivery device includes a support frame 335, the support frame 335 supports all the transmission mechanism bodies 33, and a total chamber 336 is provided at the corresponding cavity of the support frame 335, and the total chamber 336 is connected to the cavity of each transmission mechanism body 33, and the total chamber 336 is connected to the positive pressure system through a positive pressure pipe, and is connected to the positive pressure system through the first The negative pressure pipeline is connected to the first negative pressure system; an air channel 334 is provided on the transmission mechanism body 33, and the air channel 334 is connected to the total chamber 336 and the cavity; and the air channel is arranged at an angle to avoid the transmission belt 34, so that the transmission belt 34 does not affect the connection of the air channel 334; the switching element is set as a three-way valve; the three-way valve is connected to the total cavity, and is connected to the cavity in either the positive pressure system or the first negative pressure system. In this embodiment, the cavity includes several independent chambers, and the total chamber also includes several independent chambers, which are respectively connected through air channels 334.

[0132] The cavity can be a single independent chamber or multiple parallel chambers. When the cavity is a single independent chamber, the materials are preferably transferred one at a time. The transfer mechanism body 33 includes a transfer area and a discharge area. When the cavity is a plurality of parallel chambers, the cavity located in the transfer area is always maintained at a negative pressure, and the cavity located in the discharge area is connected to a positive and negative pressure system. Alternatively, a downward pressure device is provided in the corresponding transfer area to press down on the material to prevent it from being deflected by positive pressure. In this embodiment, the cavity is configured as multiple independent chambers, and the chamber near the discharge area is connected to both positive and negative pressure systems. This facilitates both material transfer and discharge.

[0133] A space is formed between the three transmission mechanism bodies 33 for the storage mechanism 5 or other equipment to pass through, so that the storage mechanism 5 or other equipment can be engaged between the transmission mechanism bodies 33, and the bridge material delivery device can deliver materials to the next device.

[0134] Preferably, the cavity at least includes: a first chamber 331 and a second chamber 332 , the first chamber 331 and the second chamber 332 are arranged in sequence along the material transmission direction, and the second chamber 332 is connected to the switch element.

[0135] In this embodiment, the transmission mechanism body 33 includes a material transmission area and a discharge area, and the second chamber 332 corresponds to the discharge area; and the size of the second chamber 332 occupies approximately half the length of the material, so that after half of the material is transmitted to the next device, the positive pressure system is started to discharge the remaining material to the next device; the first chamber 331 can be connected to the negative pressure system all the time, that is, it always maintains negative pressure, or it can be connected to the positive and negative pressure systems. At this time, a downward pressure device is set to press the material to prevent the material from being offset by positive pressure.

[0136] Preferably, the first chamber 331 is connected to a second negative pressure system.

[0137] In this embodiment, the transmission mechanism body 33 is connected to the second negative pressure system through a second negative pressure pipe; the second negative pressure system can be connected to the same negative pressure source as the first negative pressure system, and the negative pressure values ​​between them are set to be consistent, so that the material is always subjected to a balanced adsorption force, thereby ensuring that the material is not easily deformed during the transmission process.

[0138] Preferably, the bridge material delivery device further includes: a driving component and a roller 35 ; the output end of the driving component is transmission-connected to the roller 35 , and the roller 35 is connected to the conveyor belt 34 .

[0139] In this embodiment, the conveyor body 33 is configured in a rectangular parallelepiped shape. Rotating shafts are provided at both ends of the conveyor body 33 in the longitudinal direction. The conveyor belt 34 passes around the rotating shafts, and the drive assembly is positioned in the middle of the conveyor body 33. The drive element 121 is connected to the conveyor belt 34 via a roller 35. The roller 35 is positioned within the conveyor body 33 and is located in the middle of the conveyor body 33. The rollers 35 between the three conveyor bodies 33 are coaxially connected, thereby causing the conveyor belts 34 of all conveyor bodies 33 to rotate synchronously. The roller 35 is positioned within the conveyor body 33, with one end of the roller 35 extending outside the conveyor body 33 and connected to the drive assembly, making the entire bridge material transfer device more compact.

[0140] Preferably, the roller 35 is located in the middle of the transmission mechanism body 33 .

[0141] In this embodiment, the roller 35 is arranged in the middle, so that the structure of the entire bridge material delivery device is symmetrical, thereby facilitating the installation of the bridge material delivery device; in addition, space is provided for the installation of other components, thereby facilitating the installation of other components.

[0142] Preferably, Figure 19 As shown, the cavity further includes: a third chamber 333; the first chamber 331, the third chamber 333 and the second chamber 332 are sequentially arranged along the direction of material transmission, and the first chamber 331 and the third chamber 333 are respectively located on the roller 35 (see Figure 10 ) on both sides of the axis.

[0143] In this embodiment, the third chamber 333 and the second chamber 332 are arranged on one side of the axis direction of the roller 35, and the sum of the lengths of the second chamber 332 and the third chamber 333 is consistent with the length of the cavity of the first chamber 331; since the roller 35 is arranged in the middle of the transmission mechanism body 33, and the roller 35 is arranged inside the transmission mechanism body 33, the parts requiring negative pressure are arranged on both sides of the roller 35, which is convenient for controlling the negative pressure of the first chamber 331 and the third chamber 333; while ensuring that the structure of the entire transmission mechanism body 33 is compact and the volume is small, the negative pressure of the transmission material area on the transmission mechanism body 33 is ensured to be stable, thereby facilitating the transmission of materials; the negative pressures of the first chamber 331, the third chamber 333 and the second chamber 332 are all connected to the same negative pressure system.

[0144] Preferably, Figure 10 As shown, the bridge material delivery device further includes: a pressing portion 36 ; the pressing portion 36 is arranged above the transmission mechanism body 33 corresponding to the second chamber 332 ; the pressing portion 36 is used to limit the movement range of the material in the height direction.

[0145] In this embodiment, the bridge material delivery device also includes a frame 37, which is erected on both sides of the width direction of the three transmission mechanisms; the lower pressure part 36 is arranged on the frame 37 and extends toward the upper end surface of the conveying mechanism 13 body, and the lower pressure part 36 extends toward the output end of the conveying mechanism 13 body, so as to facilitate the movement of materials between the lower pressure part 36 and the conveying mechanism 13 body; since the lower pressure part 36 is provided to press the material, the material is prevented from being offset due to the action of the positive pressure system, thereby facilitating the bridge material delivery device to transfer the material to the next device.

[0146] Preferably, the pressing portion 36 is elastic.

[0147] In this embodiment, the pressing portion 36 is in contact with the upper end surface of the transmission mechanism body 33, so that when the material is subjected to the positive pressure system, it is buffered by the pressing portion 36, thereby avoiding excessive limitation by the pressing portion 36 and causing deformation of the material.

[0148] Preferably, the outer wall of the transmission mechanism body 33 forms a groove for accommodating the transmission belt 34 .

[0149] In this embodiment, the size of the conveyor belt 34 is adapted to the size of the groove. This ensures that the conveyor belt 34 rotates consistently within the groove, thereby controlling its rotational path and preventing deviation when subjected to uneven external forces. Furthermore, the upper surface of the conveyor belt 34 remains flush with the upper end surface of the conveyor mechanism body 33, facilitating both material loading and transport. A row of suction holes is provided along the length of the conveyor belt 34. This reduces the suction area and prevents deformation of the material caused by excessive suction. Furthermore, the suction holes in the conveyor belt 34 create a uniform negative or positive pressure region, ensuring that the material is subjected to a uniform negative or positive pressure.

[0150] Preferably, the bridge material delivery device also includes: a feeding detection mechanism 38 and a discharging detection mechanism 39. The feeding detection mechanism 38 is located at the input end of the bridge material delivery device, and is used to detect the material entering the bridge material delivery device, and control the opening of the second negative pressure system according to the incoming material; the discharging detection mechanism 39 is correspondingly arranged at the output end of the bridge material delivery device; when the discharging detection mechanism 39 detects that the material is discharged, it controls the positive pressure system to open, thereby facilitating the transmission and discharging of the material.

[0151] Another aspect of the present invention provides a printing device, which includes the above circulating storage device.

[0152] The above-mentioned circulating material storage device is used in a printing device, so the printing medium will be used instead of the material in further description below.

[0153] In this embodiment, since the printing device adopts the above-mentioned circulating storage device, the printing device has at least all the advantages of the circulating storage device; the volume of the entire printing device is reduced, solving the technical problem of the large volume of the existing printing device; the volume of the printing device is reduced, and then the floor space occupied by the printing device is reduced, thereby achieving the technical effect of improving the space utilization of the printing device.

[0154] Preferably, the printing device includes a plurality of circulating material storage devices, the number of the circulating material storage devices is an even number, and the output end of the upstream circulating material storage device is corresponding to the feed end of the downstream circulating material storage device.

[0155] In this embodiment, two circulating storage devices are provided. The output of the previous circulating storage device serves as the second bridge transfer device, which also serves as the feed port for the next circulating storage device. When multiple circulating storage devices are provided, the output of the previous circulating storage device serves as the feed port for the next circulating storage device, thus connecting the multiple circulating storage devices. Setting the number of circulating storage devices to an even number ensures that all materials form a cycle after the first and second circulating storage devices are exchanged. This ensures that the time intervals between each material flowing through each process are as equal as possible, thereby ensuring the transmission efficiency of each material. Providing multiple circulating storage devices allows materials to be cached for a longer period of time.

[0156] like Figure 1 As shown, the printing device further includes: a printing platform 8 for carrying and transporting the printing medium; a printing device 100, which is arranged above the printing platform 8 and is used to print fluid onto the printing medium.

[0157] In this embodiment, the fluid is varnish, and in other embodiments the fluid may also be ink or other fluids; the preset time is preferably 90 seconds, and in other embodiments the preset time may be extended or shortened as needed; the printing device 100 prints the printing medium on the printing platform 8, and after printing is completed, the printing platform 8 transfers the printed varnish printing medium to the circulating storage device, and the printing medium is stored in the circulating storage device for a certain period of time for leveling. After leveling for the preset time, the discharge mechanism 9 discharges the printing medium in the storage mechanism 5, thereby realizing caching and storing the printing medium on the printing device; there is no need to set an excessively long transmission mechanism to transport the printing medium, and leveling is performed on the circulating storage device, so that the leveling effect of the pattern on the printing medium is good, thereby ensuring the printing quality; it solves the technical problem of poor leveling effect of the existing printing equipment; it has the advantages of good leveling effect and good printing effect.

[0158] Preferably, combined Figure 1 and Figure 2The printing device also includes: a loading mechanism 1, which is used to load the printing medium and transfer it to the printing platform 8.

[0159] In this embodiment, the mechanism includes: a conveying mechanism 13 for transporting the printing medium; a feeder mechanism 11, which is arranged on one side of the conveying mechanism 13 and is used to transfer the printing medium to the feed end of the conveying mechanism 13; an adjustment mechanism 12, which is connected to the feeder mechanism 11 and drives the feeder mechanism 11 to move toward or away from the conveying mechanism 13.

[0160] like Figure 2 As shown, the feeder mechanism 11 includes: a suction nozzle 111, a blowing nozzle 112 and a lower pressure rod 113; the suction nozzle 111 is located above the printing medium to suck up the printing medium; two blowing nozzles 112 are provided, and the two blowing nozzles 112 are relatively arranged on one side of the suction nozzle 111. When working, the printing medium is located on one side of the blowing nozzle 112, and the blowing nozzle 112 is used to further blow up the uppermost printing medium and the lower printing medium, so that the uppermost printing medium is separated from the lower printing medium, which is convenient for the conveying mechanism 13 to transport the printing medium; two lower pressure rods 113 are provided, and the two lower pressure rods 113 are respectively arranged on both sides of the line connecting the blowing nozzle 112 and the suction nozzle 111; the lower pressure rod 113 is used to limit the height of the printing medium being blown up, to avoid the printing medium being blown up too high, thereby affecting the conveying of the printing medium by the conveying mechanism 13. The relative distance between the two pressing rods 113 is adjustable. Specifically, the feeder mechanism 11 includes a cross bar 114, which is arranged on the side of the blowing nozzle 112 away from the suction nozzle 111. The pressing rod 113 is movably mounted on the cross bar 114 through an adjusting member 116. The relative distance between the two pressing rods 113 is adjustable, and the relative position between the pressing rods 113 is adjusted according to the width of the printing medium, so that the pressing rod 113 can effectively press down the printing medium; the adjusting member 116 is movably arranged on the cross bar 114, and one end of the pressing rod 113 is rotatable. The adjusting member 116 is positioned to adjust the downward pressure angle of the pressing rod 113 according to the height of the print medium, allowing the pressing rod 113 to adapt to print media of different heights. A counterweight 115 is provided on the pressing rod 113, which is slidably mounted on the pressing rod 113. Adjusting the relative position between the counterweight 115 and the pressing rod 113 adjusts the downward pressure applied by the pressing rod 113. This allows the downward pressure of the pressing rod 113 to be adjusted as needed to prevent deformation of the print medium caused by excessive downward pressure from the pressing rod 113. The counterweight 115 is preferably a 10-gram counterweight 115. A bent portion is provided at one end of the pressing rod away from the crossbar 114. The bent portion is bent upward, and the end of the pressing rod 113 is relatively open, making it easier to press down on the print medium.

[0161] In this embodiment, print media are stacked below a conveyor mechanism 13, which conveys the print media from below. The feeder mechanism 11 draws the topmost print media, separating it from the underlying print media. The feeder mechanism 11 then transfers the print media to the feed end of the conveyor mechanism 13, which then conveys the print media. Due to the provision of an adjustment mechanism 12, when additional print media is needed, the adjustment mechanism 12 is activated to move the feeder mechanism 11 away from the conveyor mechanism 13, thereby increasing the distance between the conveyor mechanism 13 and the feeder mechanism 11, making it easier for the operator to place the print media below the conveyor mechanism. After the print media has been added, the adjustment mechanism 12 is activated to move the feeder mechanism 11 toward the conveyor mechanism 13, resetting the feeder mechanism 11 for the next loading step. This simple structure and convenient operation address the technical issue of the existing loading mechanism 1, which makes it difficult for the operator to place the print media. This facilitates the placement of print media.

[0162] Preferably, combined Figure 4-Figure 6 The adjusting mechanism 12 includes a driving assembly and a mounting rod 123. The driving assembly is transmission-connected to one end of the mounting rod 123. The end of the mounting rod 123 away from the mounting rod 123 is connected to the flyer mechanism 11. The driving assembly drives the mounting rod 123 to drive the flyer mechanism 11 to move toward or away from the conveying mechanism 13.

[0163] In this embodiment, the drive assembly is positioned above the conveyor mechanism 13, with the mounting rod 123 extending along the outside of the conveyor mechanism 13. The flyer mechanism 11 is positioned to one side of the conveyor mechanism 13. The drive assembly drives the mounting rod 123 upward, thereby driving the flyer mechanism 11 upward and away from the conveyor mechanism 13. This upward movement can be linear or curved, with the upward movement stopping after a certain distance to facilitate the operator placing the print medium. After the print medium is placed, the mounting rod 123 is driven to move the flyer mechanism 11 downward. Positioning the drive assembly above the conveyor mechanism 13 and the mounting rod 123 positions the flyer mechanism 11 to one side of the conveyor assembly 21, making the entire loading mechanism 1 more compact, reducing its volume and increasing its space efficiency. Furthermore, the upward movement of the flyer mechanism 11 eliminates the need for reserved horizontal space for its movement, further reducing the overall footprint of the device and improving the space efficiency of the loading mechanism 1.

[0164] Preferably, the driving assembly drives the end of the mounting rod 123 away from the driving assembly to rotate around the driving assembly.

[0165] In this embodiment, one end of the mounting rod 123 is fixed in a relative position, while the other end rotates around the drive assembly, specifically rotating upward at a certain angle, so that the flyer mechanism 11 moves away from the conveying mechanism 13. The motion path of the flyer mechanism 11 is an arc, and its projection on the horizontal plane is a straight line, specifically the projection size from the drive assembly to the end of the flyer mechanism 11. This minimizes the footprint of the flyer mechanism 11 motion path, thereby reducing the volume of the entire feeding mechanism 1 and improving the space utilization of the entire feeding mechanism 1. In other embodiments, the flyer mechanism 11 can also be driven to rotate along a horizontal plane or along a preset path.

[0166] Preferably, the driving assembly includes: a driving element 121 and a worm 122 ; the driving element 121 is drivingly connected to the worm 122 , and the worm 122 is engaged with the end of the mounting rod 123 .

[0167] In this embodiment, the driving assembly also includes a fixing seat 125, and the end of the mounting rod 123 close to the driving assembly is set to a cylindrical shape, and the axis position of the cylindrical part of the mounting rod 123 is rotatably connected to the fixing seat 125, so that the entire mounting rod 123 can rotate around the axis of the cylindrical part; the upper part of the cylindrical circumferential side wall of the mounting rod 123 is provided with helical teeth, and the end of the mounting rod 123 forms a helical gear turbine which is then engaged with the worm 122, so that the mounting rod 123 and the worm 122 form a worm 122 turbine structure; the end of the mounting rod 123 corresponding to the helical teeth extends away from the helical teeth; the driving element 121 is set to a driving motor, and the output end of the driving motor is transmission-connected to the worm 122, and the driving motor drives the worm 122 to rotate and thereby drives the mounting rod 123 to rotate, thereby driving the flyer mechanism 11 to rotate; the structure is simple and the design is compact.

[0168] Preferably, the adjustment mechanism 12 further includes a limiting member 124 , which is used to limit the rotation angle of the mounting rod 123 .

[0169] In this embodiment, specifically, the fixing seat 125 is provided with a receiving cavity for accommodating the cylindrical end of the mounting rod 123, and the end of the mounting portion 1331 is provided with a space for the mounting rod 123 to pass through, and the mounting rod 123 can rotate in the space. The limit member 124 is provided at the upper end of the fixing seat 125 to limit the height of the space, thereby limiting the upward rotation angle of the mounting rod 123.

[0170] Preferably, the relative position of the flyer mechanism 11 and the mounting rod 123 is adjustable.

[0171] In this embodiment, the feeder mechanism 11 is slidably disposed on the mounting rod 123 through a socket 15. The socket 15 is sleeved on the outer side of the mounting rod 123. The socket 15 is penetrated by a tightening screw 151, which presses the socket 15 against the mounting rod 123. By adjusting the relative position of the socket 15 and the mounting rod 123, the relative position of the feeder mechanism 11 and the mounting rod 123 can be adjusted. The relative position of the feeder mechanism 11 and the mounting rod 123 can be adjusted according to the size of the printing medium, so that the feeder mechanism 11 can effectively suck up the printing medium and send it to the feed end of the conveying mechanism 13.

[0172] Preferably, combined Figure 2 as well as Figure 3 The conveying mechanism 13 includes a suction roller 131.

[0173] In this embodiment, a plurality of suction holes are evenly distributed on the circumferential sidewall of the suction roller 131. Rotating the suction roller 131 applies a thrust to the print medium, while simultaneously adsorbing the print medium, thereby facilitating the transport of the print medium. The conveying mechanism 13 is provided with the suction roller 131. The suction roller 131 is relatively small, and its rotation can transport the print medium. This effectively transports the print medium while reducing the volume of the entire loading mechanism 1, thereby reducing the footprint of the entire loading mechanism 1 and making the entire loading mechanism 1 more compact. Specifically, the conveying mechanism 13 includes a motor assembly 132, the output end of which is in transmission connection with the suction roller 131. The motor assembly 132 drives the suction roller 131 to rotate about its own central axis. The output end of the motor assembly 132 is connected to the suction roller 131 through the synchronization assembly 133; the synchronization assembly 133 includes a mounting portion 1331, a synchronization belt 1332 and a connecting roller 1333, the mounting portion 1331 is rotatably connected to the connecting roller 1333, the connecting roller 1333 is arranged on the side of the mounting portion 1331, the connecting roller 1333 is connected to the suction roller 131, and the mounting portion 1331 is used to fix the connecting roller 1333, thereby facilitating the fixation of the suction roller 131; the synchronization belt 1332 connects the connecting roller 1333 and the output end of the motor assembly 132, so that the motor assembly 132 and the connecting roller 1333 rotate synchronously, thereby driving the suction roller 131 to rotate synchronously; the motor assembly 132 is arranged on the upper end surface of the mounting portion 1331, and synchronizes the rotation of the suction roller 131 through the synchronization assembly 133, thereby reducing the occupied area of ​​the conveying mechanism 13 on the horizontal plane, and further making the structure of the feeding mechanism 1 more compact.

[0174] Preferably, the suction roller 131 includes: a suction roller body 1311, which is used to transport the printing medium; a suction component 134, which provides negative pressure for the suction roller body 1311; the suction roller body 1311 is provided with a plurality of negative pressure channels 1312 that are not connected to each other, and the negative pressure channels 1312 are connected to the circumferential side walls of the suction roller body 1311; the suction component 134 is provided with a suction port, and the suction roller body 1311 is rotated relative to the suction component 134, and the suction channels are connected to the suction ports in turn.

[0175] In this embodiment, the suction component 134 is positioned corresponding to the lower end of the suction roller body 1311. The suction port of the suction component 134 is always connected to the negative pressure channel 1312 located at the lowest end of the suction roller body 1311. This ensures that only one suction channel experiences negative pressure at a time, preventing excessive negative pressure areas on the outer wall of the suction roller body 1311, which could cause deformation of the print medium during suction. The outlet of the negative pressure channel 1312 is positioned on a sidewall perpendicular to the axis of the suction roller body 1311. The suction component 134 corresponds to this sidewall, and the suction duct of the suction component 134 extends upward, further enhancing the compactness of the entire loading mechanism 1.

[0176] Preferably, the loading mechanism 1 further includes: a stacking mechanism 14; the stacking mechanism 14 includes a bearing portion 141, the bearing portion 141 is used to bear the printing medium, the bearing portion 141 is arranged below the conveying mechanism, and the relative position of the bearing portion 141 and the conveying mechanism 13 is adjustable.

[0177] In this embodiment, the stacking mechanism 14 is a hollow frame, located at the four corners of the carrier 141. It also includes a lifting motor 143 and guide rods 142. The lifting motor 143 is in transmission connection with the carrier 141, which supports the print media. The lifting motor 143 drives the carrier 141 up and down to adjust its height. When a certain amount of print media has been delivered from above by the conveyor mechanism 13, the lifting motor 143 drives the carrier 141 upward, guided by the guide rods 142. This ensures that the upper end of the print media maintains a certain distance from the lower end of the flyer mechanism 11, facilitating the flyer mechanism 11 to pick up the print media and the conveyor mechanism 13 to deliver the print media. Conversely, the lifting motor 143 drives the carrier 141 downward, away from the conveyor mechanism 13, similarly facilitating the operator's placement of the print media into the carrier 141.

[0178] Preferably, combined Figure 1 The printing device also includes: an oblique gauge device 2, which is arranged between the feeding mechanism 1 and the printing platform 8, and is used to transport the printing medium to the printing platform 8 according to a preset route.

[0179] In this embodiment, if Figure 7As shown, the oblique gauge device 2 includes: a conveying component 21 for transmitting the printing medium; a limiting component 22, the limiting component 22 is arranged on one side of the conveying direction of the conveying component 21, and is used to limit the printing medium; the limiting component 22 includes a first limiting surface 221 and a second limiting surface 222; the first limiting surface 221 is located on one side of the conveying direction of the conveying component 21, and the second limiting surface 222 is located above the conveying component 21; the conveying direction of the conveying component 21 is set at an acute angle to the first limiting surface 221.

[0180] In this embodiment, if Figure 8 As shown, the conveying direction is the direction indicated by the arrow a0 in the figure, that is, the printing medium moves on the conveying component 21 at a combined speed a0 toward the limit surface; the conveying component 21 is preferably configured as a conveying method of a conveyor belt, and in other embodiments, the conveying component 21 can also be configured as a conveying method of a conveyor roller; Figure 8 As shown, the printing medium is transported on the conveying component 21. Since the conveying direction of the conveying component 21 is set at an acute angle to the limiting surface, when the printing medium is transported on the conveying component 21, there is a component speed a1 parallel to the plane where the limiting surface is located, and a component speed a2 perpendicular to the first limiting surface 221. When the printing medium does not contact the limiting component 22, the printing medium is transported on the conveying component 21 toward the limiting surface of the limiting component 22 and moves at a total speed a0. When the printing medium contacts the limiting surface, the first limiting surface 221 of the limiting component 22 limits the printing medium. Therefore, the limiting surface limits the printing medium from contacting the first limiting surface 221. Vertical movement, therefore, after the printing medium contacts the limiting surface, the vertical component speed a2 is 0. At this time, the printing medium is transported at the horizontal component speed a1, that is, the limiting surface of the limiting component 22 changes the conveying direction of the printing medium to the first limiting surface 221 of the limiting component 22. Therefore, no matter where each printing medium falls when entering the conveying component 21, the printing medium will eventually move toward the limiting surface of the limiting component 22. After moving to fit with the limiting surface, the limiting surface restricts and redirects the movement direction of the printing medium, and finally makes all the printing media move along the direction of the first limiting surface 221. Therefore, the final limiting position of all the printing media is not affected by their initial position on the conveying component 21. Therefore, the installation of the limiting component 22 can limit all the printing media at the same time, solving the technical problem that the limiting component 22 of the existing conveying device is difficult to limit all the printing media at the same time.

[0181] In addition, the limiting component 22 is also provided with a second limiting surface 222, and the second limiting surface 222 is located above the conveying component 21, that is, the second limiting surface 222 is used to limit the relative position of the printing medium in the height direction, so that the limiting component 22 can limit the relative height of the printing medium in the height direction; to avoid the printing medium being displaced in the height direction due to external force when transmitting lighter printing media, thereby limiting the position of the printing medium in the height direction, so that the printing medium is positioned horizontally while limiting the displacement in the height direction.

The longitudinal adjustment member 235 can raise or lower the connecting member 231, thereby driving the limit assembly 22 to rise or fall. The height of the limit assembly 22 can be adjusted according to the thickness of the printing medium, so that the inclined gauge device 2 can adapt to printing media of different heights. In this embodiment, the limit assembly 22 is disposed on the connecting member 231. By raising and lowering the connecting member 231, and fixing one end of the connecting member 231 to the base 233, the height of the limit assembly 22 is easily adjusted, and the limit assembly 22 is less affected by its own weight and the fixing effect of the longitudinal adjustment member 23.

[0195] Preferably, two rollers 213 are provided, and the conveying assembly 21 includes a synchronous belt 215 ; the output end of the driving member 211 is connected to the two rollers 213 via the synchronous belt 215 .
