When the printing sheet body 3 needs to be printed, the printing device is arranged below the base 1, and it reaches the bottom printing sheet body 3 through the square hole, so that the bottom printing sheet body 3 can be printed. After printing, the bottom printing sheet body 3 is pushed out through the square plate structure to realize the unloading of the printing sheet body 3, and then the square plate is driven in the reverse direction to make it away from the storage rack 2. The printing sheet body 3 automatically descends under the action of its own gravity to prepare for the printing of the next printing sheet body 3 (the specific printing process can be referred to the patent document with the authorization announcement number CN220114301U). This is the prior art and will not be repeated. One of the core innovations of the embodiment of the utility model is that a groove 4 is provided at the bottom of the storage rack 2 for a single printing sheet body 3 to pass through, so that the printing The printing sheet pushing assembly is an existing reciprocating drive assembly such as a cylinder, and the placement plate 5 is located on one side of the groove 4, and the printing sheet pushing assembly is located on the other side of the groove 4. The purpose of the setting is that when it is necessary to remove the printing sheet body 3 after printing from the placement plate 5 and to transport the new printing sheet body 3 to the placement plate 5, the placement plate 5 is first moved to the side of the groove 4, and at this time, the upper surface of the placement plate 5 and the upper surface of the base 1 are at the same height, and then the printing sheet body 3 at the bottom of the storage rack 2 is pushed by the printing sheet pushing assembly, so that the printing sheet body 3 is abutted against the printing sheet body 3 on the placement plate 5, so that the printing sheet body 3 that has been printed on the placement plate 5 can be pushed down to realize unloading, and at this time, the printing sheet body 3 at the bottom of the storage rack 2 that has not been printed is moved to the placement plate 5 to realize loading, so that the loading and unloading of the printing sheet body 3 are realized simultaneously, thereby improving the printing efficiency of the printing sheet body 3.

[0031] Preferably, five seal printing areas 301 are provided on the seal body 3, and the five seal printing areas 301 are respectively corresponding to the official seal, legal person seal, financial seal, contract seal and invoice seal. The seals of the five seals are set on the same seal body 3, so that multiple seals can be printed at one time.

[0032] Furthermore, it also includes a laser printing component 6, which is fixed to the housing or the bracket by bolts and is used to perform printing operations on the printing sheet body 3.

[0033] Preferably, the printed leather pushing assembly includes a first motor 7 arranged on the base 1 and a threaded rod 8 connected to the output end of the first motor 7, a push plate 9 is slidably arranged on the base 1, the push plate 9 is threadedly connected to the threaded rod 8, and the push plate 9 is located on the other side of the groove 4. Specifically, the first motor 7 is fixedly connected to the bottom of the base 1, the push plate 9 is L-shaped, which includes a vertical edge and a horizontal edge, and the length of the horizontal edge is greater than the width of the storage rack 2, the vertical edge and the threaded rod 8 are connected by an intermediate block with a threaded hole inside, a sliding portion 34 is arranged on the base 1, the horizontal edge of the push plate 9 is slidably connected to the sliding portion 34, and the thickness of the push plate 9 is slightly smaller than the groove. 4, the purpose of such a setting is that when loading, the first motor 7 is started, and the first motor 7 drives the threaded rod 8 at its output end to rotate, thereby driving the push plate 9 to slide horizontally along the surface of the base 1 through the middle block, so that the bottom layer of the printing sheet body 3 is sent from the storage rack 2 to the placement plate 5, and the printing sheet body 3 that has been printed on the placement plate 5 is pushed down to realize the synchronous loading and unloading of the printing sheet body 3. After the loading is completed, the first motor 7 is controlled to rotate in the opposite direction, thereby driving the push plate 9 to move in the opposite direction. When the push plate 9 is away from the storage rack 2, the printing sheet body 3 moves downward under the action of its own gravity, so that the bottom layer of the printing sheet body 3 is located on the side of the push plate 9, ready for the next printing.

[0034] Furthermore, a transverse plate 10 is provided on the base 1, a first guide rail 11 is provided on the transverse plate 10, a carrying plate 12 is slidably provided on the first guide rail 11, a second guide rail 13 is provided on the carrying plate 12, and the placement plate 5 is slidably connected to the second guide rail 13. Specifically, the cross bar is fixed to the side of the base 1, the first guide rail 11 and the second guide rail 13 are both horizontally arranged, and the two are perpendicular to each other, so that the placement plate 5 can move in the X direction and the Y direction, thereby facilitating the adjustment of the horizontal position of the placement plate 5 and the printing sheet body 3.

[0035] Furthermore, it also includes a driving mechanism for driving the movement of the placement plate 5; the driving mechanism includes a transverse driving component and a longitudinal driving component. Specifically, the transverse driving component and the longitudinal driving component can both be reciprocating driving components such as electric push rods. Through the extension and retraction of the output end of the electric push rod, the X-direction and Y-direction positions of the placement plate 5 and the printing sheet body 3 can be easily adjusted.

[0036] As an alternative to the above-mentioned electric push rod, preferably, the lateral drive assembly includes a second motor 14 and a first transmission wheel 15 connected to the output end of the second motor 14, the second motor 14 is fixedly connected to the carrier plate 12, and a second transmission wheel 16 is rotatably provided on the carrier plate 12, a first transmission belt 17 is provided between the first transmission wheel 15 and the second transmission wheel 16, and the placement plate 5 is fixedly connected to the first transmission belt 17. Specifically, the first transmission wheel 15 and the second transmission wheel 16 are preferably synchronous wheels, and correspondingly, the first transmission belt 17 is preferably a synchronous belt, the second motor 14 is fixedly connected to the bottom of the carrier plate 12, and its output The outlet end passes through the top of the supporting plate 12, and the second transmission wheel 16 is rotatably arranged above the supporting plate 12 and arranged parallel to the first transmission wheel 15. A clamping plate is arranged on the placement plate 5, and the placement plate 5 is fixedly connected to the first transmission belt 17 through the clamping plate. The purpose of such a setting is that when it is necessary to adjust the position of the placement plate 5 in the X direction, the second motor 14 is started, and the second motor 14 drives the first transmission wheel 15 to rotate, and under the action of the first transmission belt 17, the second transmission wheel 16 is driven to rotate synchronously, during which the first transmission belt 17 will move. When the first transmission belt 17 moves, it will drive the placement plate 5 to move synchronously, so that the position of the placement plate 5 in the X direction can be adjusted.

[0037] Preferably, the longitudinal drive assembly includes a third motor 18 and a third transmission wheel 19 connected to the output end of the third motor 18, the third motor 18 is fixedly connected to the transverse plate 10, a fourth transmission wheel 20 is rotatably provided on the transverse plate 10, a second transmission belt 21 is provided between the third transmission wheel 19 and the fourth transmission wheel 20, the bearing plate 12 is fixedly connected to the second transmission belt 21, specifically, the third transmission wheel 19 and the fourth transmission wheel 20 are preferably synchronous wheels, and correspondingly, the second transmission belt 21 is preferably a synchronous belt, the third motor 18 is fixedly connected to the bottom of the transverse plate 10, and its output end passes through the top of the transverse plate 10, The fourth transmission wheel 20 is rotatably arranged above the supporting plate 12 and is arranged parallel to the third transmission wheel 19. A clamping plate is also arranged on the supporting plate 12, and the supporting plate 12 is fixedly connected to the first transmission belt 17 through the clamping plate. The purpose of such arrangement is that when the position of the placement plate 5Y direction needs to be adjusted, the third motor 18 is started, and the third motor 18 drives the third transmission wheel 19 to rotate, and the fourth transmission wheel 20 is driven to rotate synchronously under the action of the second transmission belt 21, during which the second transmission belt 21 will move. When the second transmission belt 21 moves, it will drive the supporting plate 12 and the placement plate 5 to move synchronously, so that the position of the placement plate 5Y direction can be adjusted.

[0038] It should be noted that when the electric push rod adjusts the position of the placement plate 5, the horizontal space it occupies is the length of the electric push rod body plus the extended length of its output end, and when the motor adjusts the position of the placement plate 5, the horizontal space it occupies basically only needs 1 / 2 of the length of the transmission belt. Therefore, adjusting the position of the placement plate 5 by the motor can reduce the horizontal space occupied by the device compared to adjusting the position of the placement plate 5 by the electric push rod.

[0039] Furthermore, a counterweight block 22 is slidably provided inside the storage rack 2. Specifically, the counterweight block 22 is preferably made of a metal material with a relatively high density. After the printing sheet body 3 is stacked inside the storage rack 2, the counterweight block 22 is placed on the top of the printing sheet body 3 to increase the force required when the printing sheet body 3 moves downward inside the storage rack 2, so as to avoid the printing sheet body 3 from getting stuck inside the storage rack 2 as much as possible.

[0040] As the bottom layer of the printing leather body 3 is continuously pushed away, the number of layers of the printing leather body 3 is continuously reduced, thereby gradually reducing the pressure on the subsequent printing leather body 3 at the bottom layer. As another embodiment of the utility model, it also includes a pressure mechanism, which includes a pressure rod 23, and a rotating shaft 24 is rotatably provided on the storage rack 2. The pressure rod 23 is rotatably connected to the rotating shaft 24, and a torsion spring (not shown in the figure) is provided between the pressure rod 23 and the rotating shaft 24. It also includes a passive adjustment member for adjusting the elastic force of the torsion spring. Specifically, the length of the pressure rod 23 is greater than the height of the storage rack 2, and an avoidance portion 25 is provided on the storage rack 2. The avoidance portion 25 protrudes from the side wall of the storage rack 2 and is rotatably connected to the two side walls of the avoidance portion 25, thereby avoiding the counterweight block 22 and the printing leather body 3 from being replenished. During the process, it interferes with the rotating shaft 24, and one end of the abutment rod 29 is rotatably connected to the rotating shaft 24. The elastic force of the torsion spring makes the other end of the abutment rod 29 abut against the upper surface of the counterweight block 22. The passive adjustment member can be a structure such as a motor for providing a rotational force, which is used to rotate the rotating shaft 24. The purpose of such a setting is that when the counterweight block 22 moves downward due to the reduction of the printing skin body 3 at its bottom, the passive adjustment member is synchronously started, thereby driving the rotating shaft 24 to rotate in the direction of the torsion spring elastic force. Since the end of the abutment rod 29 abuts against the upper surface of the counterweight block 22 and cannot rotate, the rotation of the rotating shaft 24 will cause relative rotation between itself and the abutment rod 29, thereby accumulating force on the torsion spring, so that the pressure of the pressure rod 23 on the counterweight block 22 increases, so that the force applied to the printing skin body 3 at the bottom layer is as close as possible.

[0041] As another embodiment of the present invention, Figure 4-6As shown, the passive adjustment member includes a transmission block 26, a slide groove 27 is provided on the base 1, the transmission block 26 is slidably connected with the slide groove 27, and a spring 28 is provided between the transmission block 26 and the slide groove 27, and an abutment rod 29 is provided on the counterweight block 22, and the transmission block 26 is located on the movement stroke of the abutment rod 29, and a winding wheel 30 is fixedly connected to the rotating shaft 24, and a connecting rope 31 is provided between the winding wheel 30 and the transmission block 26. Specifically, the transmission block 26 is arranged vertically and is stepped, that is, it includes multiple horizontal segments and vertical segments, and multiple wedge surfaces are provided on the transmission block 26, and the multiple wedge surfaces are respectively provided at the connection between the multiple horizontal segments and the multiple vertical segments, and the height of a single vertical segment is 8-1 2 times the thickness of the printed leather body 3, the abutment rod 29 is arranged on the side wall of the counterweight block 22, and an avoidance groove 32 adapted to the abutment rod 29 is opened on the storage rack 2, and the abutment rod 29 passes through the avoidance groove 32 to the top of the transmission block 26, and the slide groove 27 is opened on the upper surface of the base 1. There are two winding wheels 30 and connecting ropes 31, and they are symmetrically arranged about the rotating shaft 24. The connecting rope 31 is made of a metal material with low ductility, one end of which is fixed to the transmission block 26, and the other end is wound around the winding wheel 30 counterclockwise from the center of the winding wheel 30 to the outside, and the gravity of the counterweight block 22 is greater than the sum of the elastic forces of the spring 28 and the torsion spring, and a sliding hole 33 adapted to the counterweight block 22 is opened on the side wall of the storage rack 2. The effect of such a setting is that when the counterweight block 22 is When the printing leather body 3 at the bottom is reduced and moves downward, it will drive the abutment rod 29 to abut against the wedge-shaped surface at the top of the transmission block 26, thereby causing the transmission block 26 to move to the right and squeeze the spring 28. At this time, the sliding of the transmission block 26 will stretch the connecting rope 31, thereby driving the winding wheel 30 to rotate counterclockwise, thereby accumulating force on the torsion spring to achieve the pressure effect. When the abutment rod 29 is in contact with the wedge-shaped surface at the top, the abutment rod 29 will drop to the same height of the first vertical section, that is, at this time the transmission block 26 will not generate a force on the counterweight block 22. At this time, the force on the counterweight block 22 is the sum of its own gravity and the pressure of the pressure rod 23, and at this time the second wedge-shaped surface is located on the movement stroke at the end of the abutment rod 29, and the counterweight block 22 moves down to the second wedge-shaped surface. When the printing body 3 in the storage rack 2 is in the surface position, the above process is repeated to complete the multi-level adjustment of the pressure of the pressure rod 23. When all the printing bodies 3 in the storage rack 2 are loaded, the pressure rod 23 is bent clockwise to make it away from the counterweight block 22, and then the counterweight block 22 is lifted to the same vertical height as the sliding hole 33, and then the counterweight block 22 is taken out from the sliding hole 33, and then the printing body 3 is replenished from above the storage rack 2. After the replenishment is completed, the counterweight block 22 is inserted into the storage rack 2 from the sliding hole 33 again, and the pressure rod 23 is released. Under the elastic force of the torsion spring, the pressure rod 23 is again in contact with the upper surface of the counterweight block 22 to realize the entire replenishment process, and in this process, the elastic force of the spring 28 is released, thereby driving the transmission block 26 to automatically reset. The advantage of such a setting is thatWhen the counterweight 22 moves downward, the work done by gravity is transferred to the pressure rod 23, and then acts on the counterweight 22 again through the pressure rod 23, so as to realize the passive adjustment of the pressure of the bottom printing sheet body 3.

[0042] It should be noted that since the height of a single vertical segment is between 8 and 12 times the thickness of the printing sheet body 3, that is, the pressure of the pressure rod 23 is passively adjusted once 8 to 12 times after the printing of the printing sheet body 3 is completed, when the pressure rod 23 rotates downward due to the counterweight block 22, its vertical component force on the counterweight block 22 will decrease. Therefore, the value of the force generated by the transmission block 26 in the process of storing force on the torsion spring will be greater than the value of the reduction in the vertical component force on the counterweight block 22, so that the vertical force generated by the pressure rod 23 on the counterweight block 22 is always in an increasing state.

[0043] Another embodiment of the utility model provides a fully automatic seal engraving system, which includes the above-mentioned seal cover printing mechanism, that is, the fully automatic seal engraving system uses the above-mentioned seal cover printing mechanism, and the seal cover and the seal body can be automatically or manually connected to form a seal.

[0044] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
