Description

Technical Field

[0001] The present invention relates to the field of printing technology, and in particular to a printing device. Background Art

[0002] The printing device usually uses a nozzle to spray varnish on the printing medium to form a varnish pattern on the surface of the printing medium. The current printing device usually prints the printing medium and then flows it through a curing mechanism, which cures the varnish to form the desired pattern. During the printing process, the varnish needs a certain leveling time to level to a certain effect. However, in the current printing device, the printing medium sprayed with varnish is usually directly transferred to the bottom of the curing mechanism for curing; this results in insufficient leveling time for the varnish, resulting in a poor leveling effect, and the expected varnish pattern cannot be obtained, affecting the printing effect; therefore, the existing printing equipment has a technical problem of poor leveling effect.

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 pressing rods 113 are provided, and the two pressing rods 113 are respectively arranged on both sides of the line connecting the blowing nozzle 112 and the suction nozzle 111; the pressing 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 then 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 rotatably arranged on the adjusting member On the part 116, the downward pressing angle of the pressing rod 113 is adjusted according to the height of the printing medium, so that the pressing rod 113 can adapt to printing media of different heights; a counterweight block 115 is arranged on the pressing rod 113, and the counterweight block 115 is slidably arranged on the pressing rod 113. The relative position between the counterweight block 115 and the pressing rod 113 is adjusted to adjust the pressing force of the pressing rod 113, and then the pressing pressure of the pressing rod 113 can be adjusted according to the demand to avoid the deformation of the printing medium caused by excessive pressing pressure of the pressing rod 113; the counterweight block 115 is preferably set to a 10 gram counterweight block 115. A bending portion is arranged at one end of the pressing block away from the cross bar 114, and the bending portion is bent upward. The end opening of the pressing rod 113 is relatively large, which is convenient for pressing down the printing medium.

[0048] In this embodiment, the printing medium is stacked below the conveying mechanism 13, and the conveying mechanism 13 conveys the printing medium from below; the feeder mechanism 11 absorbs the printing medium located at the top, separates the printing medium at the top from the printing medium below, and transfers the printing medium to the feeding end of the conveying mechanism 13, and the conveying mechanism 13 conveys the printing medium. Since the adjustment mechanism 12 is provided, when it is necessary to add printing medium, the adjustment mechanism 12 is started to drive the feeder mechanism 11 to move away from the conveying mechanism 13, thereby increasing the distance between the conveying mechanism 13 and the feeder mechanism 11, thereby facilitating the operator to place the printing medium below the transmission mechanism; after the printing medium is added, the adjustment mechanism 12 is started to move the feeder mechanism 11 toward the conveying mechanism 13, so that the feeder mechanism 11 is reset and the next feeding is performed; the structure is simple and the operation is convenient; the technical problem that the existing feeding mechanism 1 is inconvenient for the operator to place the material is solved. It has the advantage of being convenient for placing printing medium.

[0049] 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. One 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.

[0050] In this embodiment, the driving assembly is arranged above the conveying mechanism 13, the mounting rod 123 extends along the outside of the conveying mechanism 13, the flyer mechanism 11 is located on one side of the conveying mechanism 13, and the driving assembly drives the mounting rod 123 to move upward, thereby driving the flyer mechanism 11 to move upward and away from the conveying mechanism 13; specifically, it can be a straight upward movement or a curved upward movement, and it is convenient for the operator to stop the upward movement after placing the printing medium after a certain distance of upward movement. After the material is placed, the mounting rod 123 is driven to drive the flyer mechanism 11 to move downward. The driving assembly is arranged above the conveying mechanism 13, and the mounting rod 123 is arranged so that the flyer mechanism 11 is located on one side of the conveying assembly 21, so that the structure of the entire feeding mechanism 1 is more compact, thereby reducing the volume of the entire feeding mechanism 1 and increasing the space utilization rate of the entire feeding mechanism 1. Moreover, when the flyer mechanism 11 moves upward, there is no need to reserve space for the flyer mechanism 11 to move on the horizontal plane, which further reduces the floor space of the entire equipment and further improves the space utilization rate of the feeding mechanism 1.

[0051] Preferably, the driving assembly drives one end of the mounting rod 123 away from the driving assembly to rotate around the driving assembly.

[0052] In this embodiment, one end of the mounting rod 123 is fixed in relative position, and the other end rotates around the driving assembly, specifically rotates upward at a certain angle, so that the flyer mechanism 11 is away from the conveying mechanism 13, and the motion path of the flyer mechanism 11 is an arc, and the projection on the horizontal plane is a straight line, specifically the projection size from the driving assembly to the end of the flyer mechanism 11, thereby reducing the footprint of the motion path of the flyer mechanism 11 as much as possible, 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.

[0053] 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 meshed with the end of the mounting rod 123 .

[0054] 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 and then meshes 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 then drives the mounting rod 123 to rotate, and then drives the flyer mechanism 11 to rotate; the structure is simple and the design is compact.

[0055] Preferably, the adjustment mechanism 12 further includes: a limiter 124 , and the limiter 124 is used to limit the rotation angle of the mounting rod 123 .

[0056] In this embodiment, specifically, the fixing seat 125 is provided with a accommodating 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.

[0057] Preferably, the relative position of the flyer mechanism 11 and the mounting rod 123 is adjustable.

[0058] In this embodiment, the flyer mechanism 11 is slidably set on the mounting rod 123 through the socket 15, the socket 15 is sleeved on the outside of the mounting rod 123, and 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 flyer mechanism 11 and the mounting rod 123 can be adjusted; and the relative position of the flyer mechanism 11 and the mounting rod 123 can be adjusted according to the size of the printing medium, so that the flyer mechanism 11 can effectively suck up the printing medium and send it to the feeding end of the conveying mechanism 13.

[0059] Preferably, combined Figure 2 as well as Figure 3 The conveying mechanism 13 includes a suction roller 131.

[0060] In this embodiment, a plurality of suction holes are evenly distributed on the circumferential side wall of the suction roller 131. Rotating the suction roller 131 provides a thrust to the printing medium. At the same time, the suction roller 131 absorbs the printing medium, which is convenient for transmitting the printing medium. The conveying mechanism 13 is provided with the suction roller 131. The suction roller 131 is small in size and can transmit the printing medium by rotating. Thus, while effectively transmitting the printing medium, the volume of the entire feeding mechanism 1 is reduced, thereby reducing the floor space of the entire feeding mechanism 1 and making the structure of the entire feeding mechanism 1 more compact. The specific conveying mechanism 13 includes: a motor assembly 132, the output end of the motor assembly 132 is connected to the suction roller 131 in a transmission manner; the motor assembly 132 drives the suction roller 131 to rotate around 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 fixing 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 the rotation of the suction roller 131 is synchronized by 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.

[0061] 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 which are not connected to each other, and the negative pressure channels 1312 are connected to the circumferential side wall 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 sequence.

[0062] In this embodiment, the suction component 134 is arranged corresponding to the lower end of the suction roller body 1311, and the suction port of the suction component 134 is connected to the negative pressure channel 1312 located at the lower end of the suction roller body 1311 each time. Only one suction channel has negative pressure each time, so as to avoid that the negative pressure area on the outer wall of the suction roller body 1311 is too large, which may cause deformation of the printing medium when the printing medium is adsorbed. The air outlet of the negative pressure channel 1312 is arranged on the side wall perpendicular to the axis of the suction roller body 1311, and the suction component 134 corresponds to the side wall. The suction duct of the suction component 134 is extended upward, thereby making the structure of the entire feeding mechanism 1 more compact.

[0063] 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.

[0064] In this embodiment, the stacking mechanism 14 is in the shape of a hollow frame. The stacking mechanism 14 is arranged at the four top corners of the corresponding bearing part 141 and further includes: a lifting motor 143 and a guide rod 142. The lifting motor 143 is connected to the bearing part 141 in a transmission manner. The bearing part 141 is used to carry the printing medium. The lifting motor 143 drives the bearing part 141 to rise and fall to adjust its height. When the printing medium is transported out by the conveying mechanism 13 from above by a certain amount, the lifting motor 143 drives the bearing part 141 to rise along the guide of the guide rod 142, so that the upper end surface of the printing medium always maintains a certain distance from the lower end surface of the flyer mechanism 11, so that the flyer mechanism 11 can suck up the printing medium, thereby facilitating the conveying mechanism 13 to output the printing medium. On the other hand, the lifting motor 143 drives the bearing part 141 to descend and move away from the conveying mechanism 13, which is also convenient for the operator to put the printing medium into the bearing part 141.

[0065] 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 transfer the printing medium to the printing platform 8 according to a preset route.

[0066] In this embodiment, if Figure 7As shown, the oblique gauge device 2 includes: a conveying component 21, used to transport the printing medium; a limiting component 22, which 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.

[0067] 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 limiting surface; preferably, the conveying component 21 is 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 conveying 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, since the first limiting surface 221 of the limiting component 22 limits the printing medium, the limiting surface limits the movement of the printing medium perpendicular to the first limiting surface 221. Therefore, the vertical component speed a2 after the printing medium contacts the limiting surface is 0. At this time, the printing medium moves at a horizontal component speed a 1 is used for transmission, that is, the limiting surface of the limiting component 22 changes the transmission 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 limits 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, which solves 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.

[0093] In this embodiment, the first conveying mechanism 41 can drive the storage mechanism 5 to rise and fall, and the first conveying mechanism 41 drives the storage mechanism 5 to rise to store materials; when the first conveying mechanism 41 drives the storage mechanism 5 to rise to the end of collecting the printing medium, the storage mechanism 5 is connected to the second conveying mechanism 42, and at this time, the second conveying mechanism 42 drives the storage mechanism 5 to move to the input end of the second driving component, and at this time, the storage mechanism 5 is connected to the second driving component to form the first conveying mechanism 41 to store materials and the second conveying mechanism 42 to transmit the printing medium; the conveying direction of the first conveying mechanism 41 and the conveying direction of the second conveying mechanism 42 are perpendicular to each other, so that the structure of the entire circulation mechanism 4 is simple and compact. The first driving component is set to be composed of two driving members 211, so that the storage mechanism 5 stores materials and transmits printing media separately, which is convenient for controlling the process of the entire circulation storage mechanism 5.

[0094] Preferably, the second driving component includes: a third conveying mechanism 43 and a fourth conveying mechanism 44; the output end of the third conveying mechanism 43 is arranged 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 arranged corresponding to the output end of the first driving component, and the output end of the fourth conveying mechanism 44 is arranged corresponding to the feed end of the first driving component.

[0095] In this embodiment, the second drive assembly has the same structure as the first drive assembly; specifically, the third conveying mechanism 43 can drive the storage mechanism 5 to rise and fall, and the third conveying mechanism 43 drives the storage mechanism 5 to descend to discharge materials; when the third conveying mechanism 43 drives the storage mechanism 5 to descend to discharge the printing medium, the storage mechanism 5 is connected to the fourth conveying mechanism 44, at which time, the fourth conveying mechanism 44 drives the storage mechanism 5 to move to the input end of the first drive assembly, at which time the storage mechanism 5 is connected to the first drive assembly to form the third conveying mechanism 43 to discharge materials, and the fourth conveying mechanism 44 to transport the storage mechanism 5; the conveying direction of the third conveying mechanism 43 is perpendicular to the conveying direction of the fourth conveying mechanism 44, so that the structure of the entire circulation mechanism 4 is simple and compact. The second drive assembly is configured to be composed of two driving members 211, so that the storage mechanism 5 stores materials and transmits printing media separately, which is convenient for controlling the process of the entire circulation storage mechanism 5. In other embodiments, the first drive assembly and the second drive assembly are configured to be consistent, at which time, the first drive assembly and the second drive assembly are configured to correspond to each other to form a loop.

[0096] Preferably, combined Fig.11 as well as Fig.13 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.

[0097] 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 illustrated here by way of example. The first driving member 411 and the second driving member 421 are both configured in the manner 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; when the second conveying mechanism 42 conveys the storage mechanism 5 to the second driving assembly, the matching relationship between the receiving seat 422 of the second conveying mechanism 42 and the storage mechanism 5 is destroyed. After the second driving assembly discharges the material, the second driving assembly will send the storage mechanism 5 back to the first driving member 411 and connect with the mounting seat 412. In this way, the first conveying mechanism 41 and the second conveying mechanism 42 are alternately connected to the storage mechanism 5. Since the structure of the third conveying mechanism 43 adopted in this embodiment is consistent with the structure of the first conveying mechanism 41, and the structure of the fourth conveying mechanism 44 is consistent with the structure of the second driving mechanism, the working principle of the second driving assembly will not be repeated here.

In other embodiments, multiple storage mechanisms 5 can also be set. When there are multiple storage mechanisms 5 as mentioned above, the printing medium is loaded and then output in the second drive component in turn, which speeds up the working speed of the entire device.

[0101] 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 a bidirectional guide or a unidirectional guide. 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, and 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 guide of 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 the structure of the third conveying mechanism 43 used in this embodiment 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, the working principle of the second drive assembly will not be repeated here.

[0102] Preferably, the storage mechanism 5 is slidably connected to the first driving assembly; a slide groove is provided on the storage mechanism 5, and when the first driving assembly drives the storage mechanism 5 until the slide groove corresponds to the guide mechanism 45, the first driving assembly drives the storage mechanism 5 along the guide mechanism 45 to the second driving assembly.

Specifically, a guide rail having a size consistent with the guide rail of the guide mechanism 45 is configured 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 printing media, that is, the storage mechanism 5 is located at the input end of the second conveying mechanism 42, at this time, the two guide rails are butted against each other to form a track splicing, and 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, so as to transfer 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 can also play a role in supporting the storage mechanism 5, so that the second driving member 421 can stably drive the storage mechanism 5.

[0104] Combination Fig.11 as well as Fig.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 6 is in an open state, the first conveying mechanism 41 stops conveying the storage mechanism 5.

[0105] In the present embodiment, a locking mechanism 6 is arranged 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 in connection. 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 conveyance of the storage mechanism 5 stops, the second conveying mechanism 42 transfers the storage mechanism 5. The present 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 conveyance of the storage mechanism 5 stops, thus solving the technical problem that the existing conveying device is not convenient for the conveying member 212 to convey the loading mechanism. The present embodiment has the advantages of being convenient for conveying the storage mechanism 5 and for transferring the storage mechanism 5.

[0106] Specifically, the first conveying mechanism 41 and the second conveying mechanism 42 can be independently arranged, in which case the second conveying mechanism 42 is arranged at the output end of the first conveying mechanism 41, 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, and 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 independently arranged; in this case, the input end of the second conveying mechanism 42 is arranged 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; the relative position of the second conveying mechanism 42 and the first conveying mechanism 41 is fixed, and then there is no need to use the first conveying mechanism 41 to convey the second conveying mechanism 42, thereby reducing the power of the first conveying mechanism 41 and 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 reversing transmission loading 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.

The axial direction of the plug-in 61 is perpendicular to the conveying direction of the first conveying mechanism 41, that is, the plug-in 61 is inserted into the through hole along the axial direction of the plug-in 61; in this embodiment, the conveying direction of the first conveying mechanism 41 is a vertical direction, that is, it drives the storage mechanism 5 to rise and fall; the axial direction of the plug-in 61 is parallel to the conveying direction of the second conveying mechanism 42, that is, when the second conveying mechanism 42 drives the storage mechanism 5 to move toward or away from the first conveying mechanism 41, the plug-in 61 is inserted into or disengaged from the socket 62, thereby making the locking mechanism 6 in a locked or opened state. 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 .

[0112] In this embodiment, after the stopper 63 is plugged into the socket 62, the stopper 63 rotates to the rotation space and engages with the plug-in connector 61 that leaks out of the rotation space, thereby limiting the movement of the plug-in connector 61 in its own axial direction, so that the storage mechanism 5 is fixedly connected to the first conveying mechanism 41. Specifically, a tooth is provided on one side of the stopper 63 facing the plug-in connector 61, and the plug-in connector 61 is correspondingly provided with a bayonet, and the tooth and the bayonet are adapted and engaged with each other, so that the stopper 63 is engaged with the plug-in connector 61; and when the stopper 63 is engaged with the plug-in connector 61, the stopper 63 is located in the rotation space, making the entire locking mechanism 6 compact and ingenious; thereby making the entire reversing transmission loading device more compact.

[0113] 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 .

When the second conveying mechanism 42 conveys the storage mechanism 5, the plug-in 61 with a smaller volume reduces the interference with other components. This facilitates the transmission of the plug-in 61.

When the opening member 64 touches 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 subjected to a downward force, thereby causing the limiting member 63 to rotate, thereby destroying 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, so that the plug-in member 61 is separated 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.

[0122] In this embodiment, the output end of the first conveying mechanism 41 is correspondingly arranged 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 locking 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.

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. When 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 reversing transmission loading device.

[0125] 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.

[0126] In this embodiment, the latch mechanism 7 is arranged between the second conveying mechanism 42 and the material storage mechanism 5. Specifically, the slot part can be arranged on the material storage mechanism 5, and the latch 71 can be arranged on the second conveying mechanism 42, or vice versa. The slot component 72 is provided with a slot adapted to the latch 71, and the latch 71 is plugged into the slot component 72 to connect the material storage mechanism 5 with the second conveying mechanism 42; when the second conveying mechanism 42 conveys the material storage mechanism 5 toward the first conveying mechanism 41, the material storage mechanism 5 is connected with the first conveying mechanism 41, and when the first conveying mechanism 41 drives the material storage mechanism 5, the latch 71 is disengaged from the slot component 72 to destroy the locking state of the locking mechanism 6.

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.

[0135] 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 state to apply elastic force to the fastener 73, pressing the pin 71 against the slot component 72.

[0136] Preferably, the second conveying mechanism 42 drives the storage mechanism 5 to move along the guide mechanism 45 .

The guiding mechanism 45 is provided to facilitate the transfer of the storage mechanism 5; the guiding mechanism 45 can play a guiding role, and can also play a role in supporting the storage mechanism 5, so as to prevent the latch 71 from being separated from the slot component 72 by the gravity of the storage mechanism 5 when the storage mechanism 5 is transferred, so that the second driving member 421 can stably drive the storage mechanism 5.

[0138] Preferably, the first conveying mechanism 41 includes a fixed part and a transmission part; the storage mechanism 5 is slidably arranged on the transmission part; a slide groove is arranged 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.

The guide mechanism 45 is set as a guide rail, specifically two arc-shaped parallel guide rails are set. 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 printing media, that is, the storage mechanism 5 is located at the input end of the second conveying mechanism 42, the two guide rails are connected to each other to form a track splicing.

The number of circulating material storage devices is set to an even number, so that all printing media form a cycle after the first circulating material storage device and the second circulating material storage device are exchanged, ensuring that the time interval between each printing medium flowing through each process is as equal as possible, thereby ensuring the transmission effect of each printing medium. Setting multiple circulating material storage devices allows the printing medium to be cached for a longer time.

[0142] Combination Figure 14-16 The above-mentioned material storage mechanism 5 includes: a material storage mechanism body, the material storage box is in a frame shape; a storage portion 52, the storage portion 52 is arranged between the two opposite sides of the material 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 printing medium.

[0143] In this embodiment, the storage portion 52 is used to place the printing medium. Since the storage portion 52 is provided with a pressing portion 53, the pressing portion 53 presses the printing medium tightly. After the printing medium is placed on the storage portion 52, the pressing portion 53 presses the printing medium tightly. When an external force is applied, the pressing portion 53 limits the movement of the printing medium, thereby preventing the printing medium from being displaced due to the external force. This solves the technical problem that when the existing storage mechanism 5 stores the printing medium, the printing medium is easily displaced due to the external force. The storage mechanism body is provided with a pressing portion 53 to press the printing medium tightly, which has the advantage of facilitating the storage of the printing medium.

When the printing medium enters the storage part 52, the pressing part 53 is squeezed by the printing medium, so that the pressing part 53 moves away from the printing medium. When the printing medium is in contact with the pressing part 53 and the pressing part 53 is no longer squeezed by the printing medium, the pressing part 53 stops moving, thereby making the storage mechanism 5 adaptable to printing media of different thicknesses, thereby improving the practicality of the storage mechanism 5. Specifically, when the pressing part 53 extends toward the upper plate 512, an elastic component can be arranged between the pressing part 53 and the storage part 52. When the pressing part 53 is squeezed by the printing medium, the pressing part 53 is compressed by the elastic component, so that the pressing part 53 moves downward. After the pressing part 53 is not squeezed by the printing medium and moves downward, the elastic component provides elastic force to provide a pressing force for the pressing part 53, so as to press the printing medium tightly. The elastic component can be arranged as a spring or an elastic gasket or other elastic material. When the pressing part 53 extends toward the bottom plate 511, the pressing part 53 can be movably arranged in the storage part 52, and the pressing part 53 moves upward when being squeezed by the printing medium; after the printing medium is transferred to the storage part 52, the pressing part 53 provides a pressing force to the printing medium due to its own gravity, thereby pressing the printing medium. In order to facilitate the movement of the pressing part 53, a guide component can be arranged between the pressing part 53 and the storage part 52, and the guide component can be arranged in a rod shape and passed through the storage part 52, so that the pressing part 53 can move along the guide of the guide component; further, in order to facilitate the return of the pressing part 53, an elastic component such as a spring can be passed through the guide rod 142 to provide a restoring force for the pressing part 53 to press the printing medium.

[0156] Preferably, the material storage mechanism 5 further includes a limiting portion 54 , and the limiting portion 54 is used to limit the movement of the pressing portion 53 .

[0186] Preferably, the pressing portion 36 is elastic.

[0187] In this embodiment, the pressing part 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 part 36 to avoid excessive limitation by the pressing part 36 and deformation of the material.

[0188] Preferably, the outer side wall of the transmission mechanism body 33 forms a groove for accommodating the transmission belt 34 .

[0189] In this embodiment, the airway 334 (see Fig. 20) is not connected to the groove; the size of the conveyor belt 34 is adapted to the size of the groove, which, on the one hand, facilitates the conveyor belt 34 to always rotate in the groove, thereby controlling the rotation path of the conveyor belt 34 and avoiding the conveyor belt 34 from deflecting when receiving an unbalanced external force; on the other hand, the upper surface of the conveyor belt 34 and the upper end surface of the conveyor mechanism body 33 always maintain the same horizontal plane, which is convenient for carrying and transporting materials.

The feed 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 discharge detection mechanism 39 is correspondingly arranged at the output end of the bridge material delivery mechanism; when the discharge detection mechanism 39 detects the discharge of material, it controls the positive pressure system to open, thereby facilitating the transmission and discharge of the material.

[0191] Preferably, Figure 1 As shown, the printing device further includes: a discharge mechanism 9, which is arranged at the discharge end of the circulating storage device and is used to output the printing medium from the circulating storage device in a preset order.

As the printing medium falls into the loading portion 102 , the lifting mechanism 101 drives the loading portion 102 to rise and fall, so that the upper end surface of the collected printing medium is always lower than the output end of the discharge mechanism 9 , thereby facilitating the collection of the printing medium.

[0194] Preferably, the material receiving mechanism 10 further includes: a distance measuring mechanism 103, which is used to measure the height of the collected printing medium and send a height signal to the lifting mechanism 101, so that the lifting mechanism 101 drives the loading part 102 to rise and fall.

[0195] In this embodiment, the distance measuring mechanism 103 uses an infrared sensor, and the infrared distance measuring mechanism 103 detects the distance from the upper end surface of the collected printing medium to the distance measuring mechanism 103, and sends the distance signal to the lifting mechanism 101, and the lifting mechanism 101 controls the lifting and loading part 102 according to the signal, so that the upper end surface of the printing medium is always kept at a certain height, so that the printing medium can fall into the receiving mechanism 10.

[0196] Preferably, the printing platform 8 is provided with a suction area, and the suction area of ​​the printing platform 8 is provided corresponding to the non-printing area.

[0197] In this embodiment, the printing platform 8 includes a suction area and a non-suction area, and the non-suction area is set corresponding to the printing area. When the printing medium moves on the printing platform 8, when the non-printing area on the printing medium corresponds, the nozzle is started to correspond to the printing area to print the printing medium. Since no negative pressure is generated in the corresponding printing area during printing, the possibility of negative pressure adsorbing the varnish sprayed by the nozzle is reduced, so that the varnish falls accurately on the printing medium, thereby ensuring the printing effect; it has the advantage of better printing effect.
