[0035] SUMMARY OF THE DISCLOSURE

[0036] In the process of realizing the present disclosure, the inventors found that if the information such as the production date, the expiration date and the product batch number is printed on the product packaging box (such as the medicine packaging box, etc.) by inkjet printing or laser printing, it is often necessary to set up additional printing equipment, such as inkjet printing equipment or laser printing equipment, at the end of the conveyor belt in the cartoning machine system. The space occupied by the additional equipment often expands the space occupied by the cartoning machine system, which is not conducive to optimizing the existing cartoning machine system. If the equipment for printing the information such as the production date, the expiration date and the product batch number can be inserted into the existing cartoning machine system, especially into the area where the box body flows with the conveyor belt, it is conducive to maintaining the integrity of the cartoning machine system, thereby helping to improve the integrated control degree of the cartoning machine system.

[0037] In addition, using printing media such as tacks and ink to imprint information usually has the advantage of low cost. However, this printing method often involves more printing media maintenance operations, such as adding ink, cleaning ink, etc. Therefore, when inserting a device for printing information into a cartoning machine system, not only should we consider how to better integrate the device into the cartoning machine system and quickly and conveniently print relevant information on the box body, but we should also fully consider the maintainability of the equipment. Otherwise, it may have an adverse effect on the maintenance work of the cartoning machine system.

[0038] Exemplary Overview

[0039] The technical solutions of the ink wheel stamping device and the cartoning machine system disclosed in the present invention can be applied to a variety of application scenarios. For example, the technical solutions of the ink wheel stamping device and the cartoning machine system provided in the present invention can be applied to the application scenario of drug cartoning. A specific example is Figure 1 As shown, Figure 1 The process steps included in the application scenario of drug packaging are as follows:

[0040] …

[0041] In process c, the plate-shaped medicines are successively transported to the conveying device of the cartoning machine system.

[0042] …

[0043] In process g, the folding structure in the cartoning machine system folds the instructions of the plate-shaped medicine conveyed by the conveying device, and the folded instructions are transferred to the next process by the conveying device.

[0044] …

[0045] In process m, the cartoning structure in the cartoning machine system pushes the drug instructions and the plate-shaped drugs conveyed by the conveying device into the drug packaging box, and the drug packaging box containing the drug instructions and the plate-shaped drugs is transferred to the next process by the conveying device.

[0046] …

[0047] In process p, the box folding tongue structure in the cartoning machine system performs box folding tongue processing (i.e., folding small tongue processing) on ​​the medicine packaging box conveyed by the conveying device, and then the medicine packaging box is transferred to process q by the conveying device.

[0048] In process q, the cover of the medicine packaging box passes between the wheel surface of the ink roller 72 and the wheel surface of the support wheel 74 in the ink wheel stamping device under the conveyance of the conveying device, and with the support of the wheel surface of the support wheel 74, the ink on the letter pins of the letter roller 72 is stamped on the box cover, thereby stamping the production date, expiration date and product batch number on the box cover, and the medicine packaging box is transferred to process r by the conveying device.

[0049] In process r, the box closing structure in the cartoning machine system performs a box closing process on the medicine packaging box conveyed by the conveying device, that is, the box closing structure folds the box cover and inserts it into the box body (also known as folding the tongue process), after which the medicine packaging box is transferred to the next process by the conveying device.

[0055] It should be noted that the above lists only some of the processes performed by the cartoning machine system in this application scenario, and the order of the processes listed above can also be adjusted accordingly according to actual needs.

[0056] Exemplary Devices

[0057] The structure of an embodiment of the ink wheel imprinting device disclosed in the present invention is as follows: Figure 2-12 As shown. Figure 2-12The ink wheel imprinting device shown mainly includes: an imprinting assembly 7, and the imprinting assembly 7 mainly includes: an ink-sucking wheel 71, a head roller 72, an ink wheel assembly 73 and a supporting wheel 74.

[0058] The ink wheel 71 is mainly used to pick up ink from the ink wheel assembly 73 and provide ink for the character nails on the wheel surface of the character head roller 72. The ink here is usually a printing ink with oil as the medium. In the following description, the technology disclosed in the present invention is explained by taking ink as an example.

[0059] The prefix roller 72 is mainly used to obtain ink from the ink wheel 71 and to imprint relevant information on the surface to be imprinted of the box body, such as the production date, expiration date, and product batch number. A plurality of word pins are arranged on the wheel surface of the prefix roller 72, and the height of the word pins is usually slightly higher than the height of the wheel surface of the prefix roller 72, that is, the word pins slightly protrude from the wheel surface. The specific content of the word pins can be set according to the specific application of the ink wheel imprinting device. For example, the content of the word pins may include: numbers, punctuation marks, and English letters. In one example, all word pins are usually concentrated in a partial wheel surface area of ​​the prefix roller 72, and the arrangement length of the word pins in the circumferential direction of the wheel surface of the prefix roller 72 determines the length of the information imprinted on the surface to be imprinted of the box body. In addition, the word pins on the prefix roller 72 can usually be flexibly replaced.

[0060] The ink wheel assembly 73 is mainly used to store ink and transfer the stored ink to the ink roller 71 evenly and continuously. The ink wheel assembly 73 of the present disclosure adopts a quick-release and quick-install structure, which is conducive to the daily maintenance of each component in the ink wheel assembly 73. In addition, the quick-release and quick-install structure of the ink wheel assembly 73 is conducive to providing space for the maintenance of the ink roller 71 and the head roller 72, thereby facilitating the daily maintenance operation of the ink roller 71 and the head roller 72.

[0061] In one example, the ink wheel assembly 73 mainly includes: an ink wheel 731, an ink wheel bracket 732, and an ink wheel support 736. The ink wheel 731 is mainly used to store ink, and transfer the stored ink to the ink wheel 71 evenly and continuously through rotation. The combination of the ink wheel bracket 732 and the ink wheel support 736 is mainly used to fix the ink wheel 731 while making the ink wheel 731 have the characteristics of quick disassembly and quick installation.

[0062] The axle of the ink-sucking wheel 71, the axle of the character head roller 72, the axle of the ink wheel 731 and the axle of the supporting wheel 74 are all arranged in the horizontal direction, and the above four axles are arranged in parallel.

[0063] The wheel surface of the ink-dipping wheel 71 contacts the word pins on the wheel surface of the prefix roller 72, and the wheel surface of the ink-dipping wheel 71 also contacts the wheel surface of the ink wheel 731. There is a certain distance between the word pins on the wheel surface of the prefix roller 72 and the wheel surface of the ink wheel 731, and the two are not in contact. The wheel surface of the prefix roller 72 where no word pins are set is usually not in contact with the ink-dipping wheel 71. During the rotation of the ink-dipping wheel 71, the prefix roller 72 and the ink wheel 731, the ink on the wheel surface of the ink wheel 71 is transferred to the wheel surface of the ink-dipping wheel 71, and the ink on the wheel surface of the ink-dipping wheel 71 is sequentially transferred to all the word pins. In one example, the rotation directions of the ink-dipping wheel 71 and the ink wheel 731 are opposite, and the rotation directions of the ink-dipping wheel 71 and the prefix roller 72 are opposite. In addition, a partition (such as Figure 2 As shown), the box body or operators are prevented from touching the ink on the ink wheel 71.

[0064] The support wheel 74 is located at the lower side of the head roller 72. The support wheel 74 is mainly used to support the surface to be imprinted when the head roller 72 imprints the ink on the character nail on the surface to be imprinted of the box body. In addition, the support wheel 74 can also be used together with the head roller 72 to drive the surface to be imprinted to pass between the head roller 72 and the support wheel 74 by using the friction between each and the surface to be imprinted. In one example, the box body located on the conveying device is sent by the conveying device to the position where the wheel surface of the head roller 72 and the wheel surface of the support wheel 74 are initially connected. During the rotation of the head roller 72 and the support wheel 74, the surface to be imprinted passes between the wheel surface of the head roller 72 and the wheel surface of the support wheel 74 under the action of the friction between the head roller 72 and the surface to be imprinted, the friction between the surface to be imprinted and the support wheel 74, and the movement of the finger holding the box body with the conveying device. At the same time, under the support of the wheel surface of the support wheel 74, the ink on the character nail of the head roller 72 is imprinted on the surface to be imprinted.

[0065] There may be non-tight contact or a certain gap between the wheel surface of the support wheel 74 and the wheel surface of the header roller 72, and the gap between the two is usually not greater than the thickness of the surface to be stamped. In addition, the header roller 72 and the support wheel 74 rotate in opposite directions.

[0066] The ink wheel 731 is mounted on the ink wheel bracket 732 , and the ink wheel bracket 732 is mounted on the ink wheel support 736 , so that the ink wheel 731 is fixed on the ink wheel support 736 .

[0067] An example of the ink roller support 732 is as follows Figure 4 and Figure 5 shown. Figure 4 The ink roller support 732 is not provided with the elastic pin 733. Figure 5 The ink roller bracket 732 is provided with an elastic pin 733. Figure 4 and Figure 5The ink roller support 732 shown includes: a wheel shaft 7321, a wheel sleeve 7322 and a frame body 7323. The wheel shaft 7321 is used to fix the ink roller 731. The wheel sleeve 7322 is used to form a protective cover for the ink roller 731, so as to prevent the operator from touching the ink on the ink roller 731, and also to slow down the drying time of the ink on the ink roller 731. A notch is provided on the wheel sleeve 7322, that is, the wheel sleeve 7322 is a non-closed annular sleeve, and the position of the notch should correspond to the contact area between the wheel surface of the ink roller 731 and the wheel surface of the ink-sucking wheel 71. The frame body 7323 is used to cooperate with the structure in the ink roller support 736 to fix the ink roller support 732 in the ink roller support 736. The frame 7323 is provided with an opening in the horizontal direction, and the bottom surface of the opening is provided with a pin hole, and the elastic pin 733 is arranged in the pin hole, and the top of the elastic pin 733 installed in the ink wheel bracket 732 is slightly higher than the bottom surface of the opening. Of course, the present disclosure does not exclude the situation that the elastic pin 733 is installed on the top surface of the opening. The height of the opening of the ink wheel bracket 732 is usually related to the diameter of the fixed pin in the ink wheel support 736, and the height at different positions in the opening may be different. For example, the closer to the inner end of the opening, the smaller the opening height is, and the closer to the edge of the opening, the larger the opening height is. In addition, the height of the top of the elastic pin 733 exceeding the bottom surface of the opening is mainly based on the elastic pin 733 being able to produce a certain obstruction to the displacement of the fixed pin located in the opening, so as to enhance the position stability of the fixed pin in the opening. Of course, the height of the elastic pin 733 exceeding the bottom surface of the opening should also ensure that when the ink wheel bracket 732 is pushed or pulled by external force, the elastic pin 733 can be compressed by the fixed pin, so that the fixed pin withdraws from the opening.

[0068] The fixing pin provided on the ink roller support 736 in the present disclosure is mainly used to cooperate with the opening on the ink roller bracket 735 and the elastic pin 733, so as to conveniently fix the ink roller bracket 735 on the ink roller support 736, and enable the ink roller bracket 735 to be conveniently separated from the ink roller support 736, thereby realizing quick installation and removal of the ink roller 731.

[0069] In one example, the process of installing the ink roller bracket 732 into the ink roller support 736 includes: aligning the opening of the ink roller bracket 732 with the fixing pin installed on the ink roller support 736, and pushing the ink roller bracket 732 in the horizontal direction so that the fixing pin enters the opening of the ink roller bracket 732. When the fixing pin enters the position of the elastic pin 733 in the opening, the elastic pin 733 is compressed by the fixing pin, thereby opening a channel for the fixing pin to continue to enter the opening until the fixing pin is fully abutted against the inner end of the opening, that is, the fixing pin is in place in the opening. At this time, the elastic pin 733 should be in a released compressed state, and the fixing pin is stuck in the inner end of the opening, thereby fixing the ink roller bracket 732 on the ink roller support 736.

[0070] In one example, the process of removing the ink roller bracket 732 from the ink roller support 736 includes: pulling the ink roller bracket 732 in the horizontal direction, the pulling force causes the fixing pin to squeeze the elastic pin 733, the elastic pin 733 is compressed by the fixing pin, thereby opening a channel for the fixing pin to continue to withdraw from the opening, when the fixing pin passes the position of the elastic pin 733, the compression of the elastic pin 733 is released, and when the fixing pin is completely withdrawn from the opening, the ink roller bracket 732 is completely separated from the ink roller support 736.

[0071] From the above description of installing and removing the ink roller bracket 732, it can be seen that the process of installing and removing the ink roller bracket 732 does not require the use of any tools, and only requires applying a push or pull force on the ink roller bracket 732, so that the ink roller assembly 73 has the characteristics of quick removal and installation, which greatly facilitates the daily maintenance of the ink roller 731.

[0072] By providing ink for the ink wheel 71 and the ink wheel 71 providing ink for the nails on the head roller 72, it is beneficial to make the ink stained by the nails uniform in thickness, thereby facilitating clear information printing; since the axles of the ink wheel 71, the head roller 72, the ink wheel 731 and the support wheel 74 are all arranged in parallel in the horizontal direction, and the surface to be stamped of the box body passes between the wheel surface of the head roller 72 and the wheel surface of the support wheel 74 along the tangent direction of the wheel, the ink wheel stamping device can be arranged on one side of the conveying device of the cartoning machine system like many structures in the cartoning machine system, which not only makes full use of the space of the cartoning machine system, but also helps to increase the number of processes completed by the box body with the circulation of the conveying device, so that the box body ink wheel stamping device can be better integrated into the cartoning machine system; by arranging elastic pins 733 and The ink roller bracket 732 is opened and a fixing pin is set on the ink roller support 736. When installing the ink roller bracket 732, it only needs to push the ink roller bracket 732 into the ink roller bracket 736 along the opening direction. The cooperation of the elastic pin 733 and the fixing pin can fix the ink roller bracket 732 in the ink roller bracket 736. When disassembling the ink roller bracket 732, it only needs to pull the ink roller bracket 732 in the reverse direction so that the elastic pin 733 is compressed by the fixing pin, so that the ink roller bracket 732 can be separated from the ink roller support 736, thereby realizing the quick disassembly and installation of the ink roller 731, which is beneficial to improving the maintenance convenience of the ink roller 731, and at the same time is beneficial to improving the maintenance convenience of the head roller 72 and the ink-dipping roller 71. It can be seen that the technical solution provided by the present invention is beneficial to reducing the maintenance workload of the device and improving the degree of integrated control of the cartoning machine system while ensuring the printing quality and reducing the printing cost.

[0073] In one example, two fixing pins may be provided on the ink wheel support 736, the sizes of the two fixing pins are usually the same, and the fit between the two fixing pins and the opening of the ink wheel support 732 is a clearance fit, and it can also be considered that the fit between the two fixing pins and the ink wheel support 732 is a clearance fit. One of the clearance fits is a tight clearance fit, and the other clearance fit is a loose clearance fit. In other words, the gap between one of the fixing pins and the opening of the ink wheel support 732 is greater than the gap between the other fixing pin and the opening of the ink wheel support 732. The tight clearance fit here can be a minimum clearance fit, that is, the gap between the two is zero, and the loose clearance fit here usually means that the gap between the two is greater than zero and is within a predetermined range.

[0074] An example of an ink wheel support 736 having two fixing pins is shown in FIG. Figure 6 shown. Figure 6 In the embodiment, the ink wheel support 736 is provided with a first fixing pin 734 and a second fixing pin 735. Figure 5 The ink roller support 735 shown is installed to Figure 6 The process on the ink roller support 736 shown includes: aligning the opening of the ink roller support 732 with the first fixing pin 734 installed on the ink roller support 736, and pushing the ink roller support 732 in the horizontal direction, so that the first fixing pin 734 and the second fixing pin 735 successively enter the opening of the ink roller support 732, when the first fixing pin 734 enters the position of the elastic pin 733 in the opening, the elastic pin 733 is compressed by the first fixing pin 734, thereby opening a channel for the first fixing pin 734 to continue to enter the opening, until the first fixing pin 734 is fully abutted against the inner end of the opening, and the two are tightly matched with each other (that is, the first fixing pin 734 and the ink roller support 732 are tightly matched with each other), at this time, the elastic pin 733 is in a released and compressed state, so that the first fixing pin 734 is stuck in the inner end of the opening, and the second fixing pin 735 is loosely matched with the opening (that is, the second fixing pin 735 is loosely matched with the ink roller support 732), so that the ink roller support 732 is fixed on the ink roller support 736, and the state after installation is as shown in FIG. Figure 3 and Figure 7 As shown. Figure 3 The perspective method is used to show the tight clearance fit between the first fixing pin 734 and the inner end of the opening, and the loose clearance fit between the second fixing pin 735 and the opening. The process of removing the ink roller bracket 732 from the ink roller support 736 includes: pulling the ink roller bracket 732 in the horizontal direction, the pulling force causes the first fixing pin 734 to squeeze the elastic pin 733, and the elastic pin 733 is compressed by the first fixing pin 734, thereby opening a channel for the first fixing pin 734 to continue to withdraw from the opening. When the first fixing pin 734 and the second fixing pin 735 are completely withdrawn from the opening, the ink roller bracket 732 is completely separated from the ink roller support 736.

[0075] Since the first fixing pin 734 and the ink roller bracket 732 have a tight clearance fit, and the second fixing pin 735 and the ink roller bracket 732 have a loose clearance fit, the ink roller bracket 732 can rotate at a small angle around the first fixing pin 734, so that the tight clearance fit and the loose clearance fit disclosed in the present invention form a self-balancing structure. When there is a certain pressure between the ink wheel 71 and the ink wheel 731 (the pressure can be generated by the pneumatic structure described below), and when there is a processing error between the ink wheel 71 and the ink wheel 731, the self-balancing structure can be used to compensate for the error, thereby preventing the ink wheel 71 from being unevenly ink-stained.

[0076] In one example, the ink wheel imprinting device disclosed in the present invention further includes: a pneumatic structure. The pneumatic structure is connected to the ink wheel support 736, and is mainly used to control the distance between the ink wheel 71 and the ink wheel 731 by controlling the movement of the ink wheel support 736, for example, controlling the wheel surface of the ink wheel 71 and the wheel surface of the ink wheel 731 to contact each other (such as close contact with a certain pressure), and for another example, controlling the wheel surface of the ink wheel 71 and the wheel surface of the ink wheel 731 to separate from each other. The pneumatic structure mainly includes: a cylinder 75, a pneumatic support 76 and at least one first guide column 77. In addition, the pneumatic structure may also include: a frame 78. Fig. 9 As shown, the ink roller support 736 on which the ink roller support 73 is installed is fixed on the pneumatic support 76, the first guide column 77 is arranged in the pneumatic support 76 along the vertical direction, and the cylinder 75 is mainly used to support the pneumatic support 76. Specifically, when the supporting force of the cylinder 75 is increased, the pneumatic support 76 moves upward along the first guide column 77 under the support of the cylinder 75, thereby driving the ink roller support 736 on the pneumatic support 76 to move upward, and then the ink roller 731 moves upward, and finally the wheel surface of the ink roller 731 is separated from the wheel surface of the ink-sucking wheel 71. On the contrary, when the supporting force of the air cylinder 75 is reduced, the pneumatic support 76 moves downward along the first guide column 77 under the action of gravity, thereby driving the ink wheel support 736 on the pneumatic support 76 to move downward, and then the ink wheel 731 moves downward, and finally the wheel surface of the ink wheel 731 contacts the wheel surface of the ink wheel 71, and a certain pressure can be formed on the wheel surface of the ink wheel 71. The pressure can form a certain friction force between the ink wheel 731 and the ink wheel 71, so that the ink wheel 731 can rotate with the rotation of the ink wheel 71 based on the friction force. The frame 78 will not move with the movement of the pneumatic support 76, and the frame 78 is mainly used to fix the air cylinder 75, the pneumatic support 76 and the first guide column 77.

[0077] The present invention provides a pneumatic structure connected to the ink wheel support 736, and uses the pneumatic structure to control the movement of the ink wheel support 736, so as to flexibly control the contact state between the wheel surface of the ink wheel 731 and the wheel surface of the ink wheel 71. For example, when there is no box body that needs to be processed by the ink wheel stamping device on the conveyor belt, the wheel surface of the ink wheel 731 and the wheel surface of the ink wheel 71 can be controlled to be separated, and when there is a box body that needs to be processed by the ink wheel stamping device on the conveyor belt, the wheel surface of the ink wheel 731 and the wheel surface of the ink wheel 71 can be controlled to contact each other, thereby helping to avoid ink waste. In addition, since the pneumatic structure can control the pressure between the wheel surface of the ink wheel 731 and the wheel surface of the ink wheel 71, the friction between the two can be controlled, so that the ink wheel 731 can rotate with the rotation of the ink wheel 71 based on the friction force, and it is no longer necessary to set an additional driving structure for the ink wheel 731, thereby helping to simplify the structure of the ink wheel stamping device.

[0078] In one example, the ink wheel imprinting device disclosed in the present invention further includes: a transmission assembly. The transmission assembly is mainly used to provide power to the ink wheel 71, the letterhead roller 72, the support wheel 74 and other components to achieve normal operation of each component. The transmission assembly is connected to the ink wheel 71, the letterhead roller 72, the support wheel 74 and other components respectively, and the connection can be an indirect connection. Figure 8 As shown, the transmission assembly mainly includes: a main pulley 1, a slave pulley 2, an overload clutch 3 and a spline 5. The main pulley 1 and the slave pulley 2 are connected by a belt, and a tensioner can be arranged between the main pulley 1 and the slave pulley 2 to adjust the tensioning frequency between the main pulley 1 and the slave pulley 2 to avoid the belt between the main pulley 1 and the slave pulley 2 from loosening, thereby ensuring the stability of the power provided by the transmission assembly.

[0079] The main pulley 1 is mainly used to introduce the power transmitted from the outside into the ink wheel imprinting device and transmit it to the slave pulley 2. The slave pulley 2 is also connected to the spline 5. The power introduced into the ink wheel imprinting device by the main pulley 1 is provided to the ink wheel 71, the prefix roller 72 and the support wheel 74 via the slave pulley 2 and the spline 5. An overload clutch 3 is provided on the slave pulley 2. When an abnormal phenomenon such as the surface to be imprinted being stuck between the prefix roller 72 and the wheel surface of the support wheel 74 occurs, the slave pulley 2 tends to run in overload (such as the load exceeds a preset threshold). At this time, the overload clutch 3 will automatically control the slave pulley 2 to disengage from the spline 5, so that the power will no longer continue to be transmitted forward, thereby avoiding the power to the front-end equipment (such as Figure 8 The left part in the middle) can be prevented from being damaged, thus protecting the front-end equipment.

[0080] In one example, the ink wheel stamping device of the present disclosure further includes: a sensor 4. The sensor 4 is usually arranged at the position of the pulley 2. The sensor 4 is mainly used to be triggered when the overload clutch 3 disengages the pulley 2 from the spline 5, to form an overload signal, and report the overload signal to the control center in the cartoning machine system where the ink wheel stamping device is located. After receiving the overload signal, the control center can cut off the power of the ink wheel stamping device, and the ink wheel stamping device is in a shutdown state. Further, the control center can cut off the power of the cartoning machine system, so that the entire system is in a shutdown state. The sensor 4 in the present disclosure can be specifically a magnetic switch.

[0081] When the pulley 2 is separated from the spline 5, the ink wheel stamping device no longer performs ink wheel stamping on the box body on the conveying device of the cartoning machine system. At this time, if other structures in the cartoning machine system continue to operate, the box body that has not been stamped by the ink wheel will continue to flow to the next process, so that the box body finally formed will not be printed with relevant information. The present disclosure sets a sensor 4 to report an overload signal to the control center, especially when the sensor 4 is a magnetic switch, the overload signal can be reported to the control center in time, so that the control center can timely control the cartoning machine system to be in a shutdown state, which is conducive to avoiding the occurrence of the above phenomenon.

[0082] In one example, the ink wheel stamping device disclosed in the present invention further includes: a horizontal depth adjustment component. The horizontal depth adjustment component is mainly used to adjust the depth of the information printed by the ink wheel stamping device on the surface to be stamped in the horizontal direction, such as Fig.10 Arrows pointing left and right. Fig.10 The leftward arrow indicates that the information printed by the ink wheel stamping device on the surface to be stamped is closer to the box body, and the rightward arrow indicates that the information printed by the ink wheel stamping device on the surface to be stamped is farther away from the box body. The horizontal depth adjustment component mainly includes: at least one second guide column 52 (such as Fig.10 , Fig.11 as well as Fig.12Two second guide columns are shown in the figure), an adjustment block 53 and a fastener 54. In addition, the horizontal depth adjustment assembly may also include: a frame 55. The second guide column 52 is arranged in the adjustment block 53 along the horizontal direction, such as penetrating the main part of the adjustment block 53 in the horizontal direction. The adjustment block 53 is used to support various components that need to be adjusted in the horizontal direction. For example, the adjustment block 53 can support the ink wheel 71, the head roller 72, the ink wheel assembly 73 and the support wheel 74. The fastener 54 is arranged on the adjustment block 53, and the fastener 54 is mainly used to determine whether the adjustment block 53 is allowed to move along the second guide column 52. Specifically, when the fastener 54 is locked, the adjustment block 53 is fixed at a corresponding position on the second guide column 52, and when the fastener 54 is loosened, the adjustment block 53 can move horizontally along the second guide column 52 under the action of external force, thereby driving the ink wheel 71, the character head roller 72, the ink wheel assembly 73 and the support wheel 74 to move horizontally, thereby adjusting the depth of the ink on the character pins on the character head roller 72 being imprinted in the horizontal direction on the surface to be imprinted, and avoiding the phenomenon that the imprinted information appears outside the preset area (such as too close to the edge of the surface to be imprinted, etc.). The fastener 54 of the present disclosure can be specifically a handle that can be tightened and loosened (such as a handle that can be tightened and loosened). Fig.11 The frame 55 is mainly used to fix the second guide column 52 and the adjustment block 53.

[0083] By setting a horizontal depth adjustment component, the depth of the ink on the character pins on the head roller 72 being imprinted in the horizontal direction on the surface to be imprinted is adjusted, so that the ink wheel imprinting device can imprint information at appropriate positions on surfaces to be imprinted of different sizes, thereby avoiding the phenomenon that the ink wheel imprinting device can only imprint information on a surface to be imprinted of one specification, and the ink wheel imprinting device can cope with boxes with surfaces to be imprinted of different sizes, thereby helping to improve the flexibility of the ink wheel imprinting device.

[0084] In one example, the ink wheel stamping device of the present disclosure further includes: a height adjustment component 6. The height adjustment component 6 is mainly used to adjust the height of the information printed by the ink wheel stamping device according to the height of the surface to be stamped, such as Fig.10 Up and down arrows are shown. Fig.10 The upward arrow in the middle indicates that when the box body is thicker, the height of the surface to be stamped of the box body is usually higher, and the ink wheel stamping device needs to adjust the height of the printed information upward to match the height of the surface to be stamped; the downward arrow indicates that when the box body is thinner, the height of the surface to be stamped of the box body is usually lower, and the ink wheel stamping device needs to adjust the height of the printed information downward to match the height of the surface to be stamped. The height adjustment component 6 mainly includes: at least one third guide column 61, a bearing seat 69, and at least one cantilever (such as Fig.11 and Fig.12Two cantilevers are shown in FIG. 1 ). The third guide column 61 is arranged in the vertical direction between the adjustment block 53 and the bearing seat 69, as shown in FIG. Fig.10 , Fig.11 and Fig.12 As shown, the third guide column 61 passes through the main body of the adjustment block 53 and the bearing seat 69 in the vertical direction. The bearing seat 69 is arranged above the adjustment block 53 through a cantilever, and the ink-sucking wheel 71, the character head roller 72, the ink wheel assembly 73 and the support wheel 74 are all fixed on the bearing seat 69. The bearing seat 69 and the cantilever together provide the power transmitted by the spline 5 to the ink-sucking wheel 71, the character head roller 72 and the support wheel 74 respectively. The position change of the bearing seat 69 along the third guide column 61 in the vertical direction is controlled by the cantilever. Specifically, when the cantilever is directed to a different direction, the bearing seat 69 moves in the vertical direction along the third guide column 61. For example, the closer the angle between the cantilever and the horizontal direction is to 90 degrees, the more the bearing seat 69 moves upward along the third guide column 61; the closer the angle between the cantilever and the horizontal direction is to 0 degrees, the more the bearing seat 69 moves downward along the third guide column 61. The bearing seat 69 drives the ink wheel 71, the head roller 72, the ink wheel assembly 73 and the support wheel 74 to move upward or downward, thereby allowing the surface to be imprinted of boxes of different specifications to always pass between the nails on the head roller 72 and the wheel surface of the support wheel 74, thereby avoiding the phenomenon that the surface to be imprinted is too high or too low to be imprinted.

[0085] By setting a height adjustment component 6 to adjust the height of the ink-dipping wheel 71, the character roller 72, the ink wheel component 73 and the support wheel 74, the ink wheel imprinting device can imprint information on boxes of different thicknesses, thereby avoiding the phenomenon that the ink wheel imprinting device can only imprint information on the to-be-imprinted surface of a box of one thickness specification, so that the ink wheel imprinting device can cope with boxes of different thicknesses, thereby helping to improve the flexibility of the ink wheel imprinting device.

[0086] It should be particularly noted that when the specifications of the box body change, resulting in a change in the thickness of the box body, on the one hand, the size of the surface to be imprinted of the box body (such as the length and width of the surface to be imprinted) will often change accordingly, and on the other hand, the height of the position of the surface to be imprinted of the box body will also change accordingly. Therefore, when the thickness of the box body changes, it is often necessary to adjust the horizontal depth adjustment component and the height adjustment component 6 at the same time to ensure that the ink wheel imprinting device imprints information in a suitable area of ​​the surface to be imprinted.

[0087] In one example, cantilever pulleys are respectively provided at both ends of the cantilever in the present disclosure, and the two cantilever pulleys respectively provided at both ends of a cantilever are driven by a belt, and the cantilever pulley provided at the uppermost end is connected to the bearing seat 69, and the cantilever pulley drives the ink wheel 71, the letterhead roller 72 and the support wheel 74 to rotate respectively through the bearing seat 69. The ink wheel 731 can rotate by relying on the friction between it and the ink wheel 71. Of course, the present disclosure does not exclude the possibility that the cantilever pulley drives the ink wheel 731 to rotate through the bearing seat 69. The cantilever pulley provided at the lowermost end is connected to the spline shaft 51 of the spline 5, and the cantilever pulley is used to provide the power transmitted from the spline shaft 51 to the cantilever pulley at the uppermost end step by step. The cantilever in the present disclosure can rotate around a fixed axis thereof.

[0088] By arranging cantilever pulleys at both ends of the cantilever, no matter how the direction of the cantilever changes by rotating around its fixed axis, the power transmitted by the spline 5 can be smoothly transmitted to the bearing seat 69 through the cantilever pulley, thereby being able to conveniently adjust the height of the ink-dipping wheel 71, the head roller 72, the ink wheel assembly 73 and the support wheel 74, while also being conducive to ensuring the working stability of the ink wheel imprinting device.

[0089] In one example, the ink wheel imprinting device of the present disclosure is provided with two cantilevers, namely Fig.12 The first cantilever 66 and the second cantilever 67 are shown. In the case of multiple cantilevers, two cantilevers connected to each other can share a cantilever pulley at the connection position. Fig.12 The lower end of the first cantilever 66 is provided with a first cantilever pulley 63, the upper end of the first cantilever 66 and the lower end of the second cantilever 67 share a cantilever pulley, namely, the second cantilever pulley 64, the upper end of the second cantilever 67 is provided with a third cantilever pulley 65, a belt is provided between the first cantilever pulley 63 and the second cantilever pulley 64, and a belt is provided between the second cantilever pulley 64 and the third cantilever pulley 65, the first cantilever pulley 63 is connected to the spline shaft 51 of the spline 5, so that the power transmitted from the spline shaft 51 is transmitted to the bearing seat 69 via the belt provided between the first cantilever pulley 63 and the second cantilever pulley 64, and the belt provided between the second cantilever pulley 64 and the third cantilever pulley 65. Both ends of the first cantilever 66 and the second cantilever 67 are provided with fixed shafts, such as Fig.12 The first cantilever 66 can rotate around one of the fixed axes (such as Fig.12 The second cantilever 67 can rotate around any fixed axis (such as the fixed axis C) to change the direction of the first cantilever 66; and the second cantilever 67 can rotate around any fixed axis (such as the fixed axis C) under the action of external force. Fig.12 The fixed axis B or the fixed axis A) in the middle rotates to change the direction of the second cantilever 67.

[0090] By providing the first cantilever 66 and the second cantilever 67, and providing cantilever pulleys and a fixed shaft that can rotate the cantilever on the two cantilevers respectively, the position adjustment of the bearing seat 69 is more flexible, and the support for the bearing seat 69 is also more stable.

[0091] In one example, the first cantilever 66 and the second cantilever 67 of the present disclosure are cantilever with variable cantilever lengths. For example, the first cantilever 66 and the second cantilever 67 are respectively provided with cantilever length adjustment members, such as Fig.12 The cantilever length adjustment member is mainly used to control the arm length of the first cantilever 66 and the second cantilever 67, so as to control the tension frequency of the belt between the first cantilever pulley 63 and the second cantilever pulley 64, and the tension frequency of the belt between the second cantilever pulley 64 and the third cantilever pulley 65. The specific process of controlling the cantilever arm length can be: loosen Fig.12 After turning the knob in the middle, pull the upper end of the first cantilever 66 to extend the first cantilever 66 to a suitable position, and then tighten the knob to fix the length of the first cantilever 66.

[0092] By using the cantilever length adjustment part to control the tensioning frequency of the belt between the cantilever pulleys, it is helpful to avoid the loosening of the belt between the cantilever pulleys due to changing the cantilever direction, thereby ensuring the stability of the rotation speed of the ink wheel 71, the head roller 72 and the support wheel 74, and further ensuring the working stability of the ink wheel imprinting device.

[0093] Exemplary Systems

[0094] An embodiment of a partial structure in a cartoning machine system of the present disclosure is as follows: Fig.13 As shown. Fig.13 The cartoning machine system shown mainly includes: an ink wheel stamping device and a conveying device. The specific structure of the ink wheel stamping device is as described in the above device embodiment. Figure 2-12 The description of is omitted here. The conveying device mainly includes: a conveyor belt and multiple pairs of fingers. The conveyor belt is mainly used to convey materials, for example, to transfer materials such as box bodies and instructions between various processes in the cartoning machine system. The fingers are mainly used to limit the position of the box body on the conveyor belt, and the two opposite surfaces of a box body are clamped by at least one pair of fingers. The box body clamped by at least one pair of fingers is conveyed to the ink wheel stamping device as the conveyor belt runs. The surface of the box body to be stamped passes between the wheel surface of the head roller 72 and the wheel surface of the support wheel 74. At the same time, the ink on the character pins of the head roller 72 is stamped on the surface to be stamped with the support of the wheel surface of the support wheel 74. A specific example of a finger is as follows Figure 2 As shown, Figure 2The box body is clamped and fixed by two pairs of fingers. The spacing between a pair of fingers can be flexibly adjusted according to the width of the box body, and the distance between the two pairs of fingers arranged front and back can be flexibly set according to the length of the box body. The fingers can be set on the conveyor belt, and the height of the fingers extending out of the conveyor belt can be set according to actual conditions. The running speed of the conveyor belt in the present disclosure should be the same as the linear speed of the prefix roller 72, that is, the speed at which the surface to be stamped passes between the wheel surface of the prefix roller 72 and the wheel surface of the support wheel 74 should be the same as the linear speed of the prefix roller 72 and the support wheel 74.

[0095] Since the ink wheel imprinting device can be arranged on one side of the conveying device of the cartoning machine system like many structures in the cartoning machine system, it not only makes full use of the space of the cartoning machine system, but also helps to increase the number of processes completed by the box body as the conveyor belt rotates, thereby helping to improve the integrity of the cartoning machine system, and further helps to improve the degree of integrated control of the cartoning machine system; in addition, since the ink wheel imprinting device also has the characteristics of clear imprinting information, low printing cost and easy maintenance, it is helpful to improve the practicability of the cartoning machine system.

[0096] In one example, the cartoning machine system of the present disclosure further includes: a box folding tongue structure and a box closing structure, and the ink wheel stamping device is arranged between the box folding tongue structure and the box closing structure. The box folding tongue structure is used to fold the box tongue (such as Fig.14 The folded box body tongue) is shown, so that the box tongue (i.e. Fig.14 The small tongue in the box body) is located at a preset position of the box body, such as when the box tongue is folded at 90 degrees. After the box body is subjected to the folding box tongue structure, it is conveyed to the ink wheel stamping device by a conveyor belt. Under the clamping of at least one pair of fingers, the surface of the box body to be stamped passes between the wheel surface of the prefix roller 72 and the wheel surface of the support wheel 74. At the same time, supported by the wheel surface of the support wheel 74, the ink on the character pins of the prefix roller 72 is stamped on the surface to be stamped. After that, the box body is conveyed to the box closing structure by a conveyor belt. The box closing structure is used to fold the lid of the box body (such as Fig.14 The folding box body shown in the figure) makes the box cover (i.e. Fig.14 The large tongue in the box body is buckled in the cavity of the box body to form a closed box body. By arranging the ink wheel stamping device between the box folding tongue structure and the box closing structure, the process flow of the cartoning machine system is more reasonable and smoother.

[0097] In one example, the cartoning machine system disclosed in the present invention further includes: a control center. The control center can be implemented by a PLC (programmable logic controller), and the control center is connected to multiple structures in the system. The control center is mainly used to receive information reported by each structure in the system and control the corresponding structure in the system to ensure the normal operation of the system and the safety of the system. For example, when the control center receives an overload signal reported by the sensor 4 in the ink wheel stamping device, it cuts off the power of the main pulley 1 in the ink wheel stamping device to avoid the phenomenon that the main pulley 1 is still idling when the ink wheel stamping device is abnormal. In addition, when the control center receives an overload signal, it can not only switch the power of the main pulley 1 of the ink wheel stamping device, but also cut off the power of the system, so that the entire system is in a stopped working state, which is convenient for operators to perform equipment maintenance to eliminate faults.

[0098] In one example, the control center can also be used to: when it is detected that there is no box to be stamped at the station of the ink wheel stamping device currently transferred to by the conveyor belt, control the cylinder 75 in the ink wheel stamping device to increase the supporting force of the supporting pneumatic bracket 76, so that the pneumatic bracket 76 moves upward along the first guide column 77, thereby driving the ink wheel support 736 provided on the pneumatic bracket 76 to move upward, and then the ink wheel 731 in the ink wheel support 736 moves upward, and finally the wheel surface of the ink wheel 731 is separated from the wheel surface of the ink-dipping wheel 71. In this way, when the cartoning machine system is idling or a box at a certain position on the conveyor belt is missing, it can be avoided that the ink on the wheel surface of the ink wheel 731 is still transferred to the wheel surface of the ink-dipping wheel 71 to cause ink waste. On the contrary, when it is detected that there is a box body on the conveyor belt that needs to be processed by the ink wheel stamping device (for example, the missing position of the box body has left the ink wheel stamping device with the conveyor belt, and the next box body is conveyed to the ink wheel stamping device), the control center can control the cylinder 75 in the ink wheel stamping device to reduce the supporting force of the supporting pneumatic bracket 76, so that the pneumatic bracket 76 moves downward along the first guide column 77 under the action of gravity, thereby driving the ink wheel support 736 set on the pneumatic bracket 76 to move downward, thereby causing the ink wheel The ink wheel 731 in the support 736 moves downward, and finally the wheel surface of the ink wheel 731 presses down the wheel surface of the ink-dipping wheel 71, that is, the wheel surface of the ink wheel 731 forms a certain pressure on the wheel surface of the ink-dipping wheel 71, and this pressure forms a certain friction force between the ink wheel 731 and the ink-dipping wheel 71. The friction force can be used to make the ink wheel 731 rotate as the ink-dipping wheel 71 rotates, so that there is no need to use the power from the spline shaft 51 to drive the ink wheel 731, which is beneficial to simplify the structure of the ink wheel imprinting device.
