[0002] Cutting machines are widely used in different industries and scenarios, and different scenarios require different cutting machines. In the printing industry, cutting is a very important process. Generally, an independent device is used for the cutting process. The device is equipped with a cutter. Different types of cutting machines are divided according to the size of the paper, the thickness of the paper stack, and the purpose.

Utility Model Content

[0003] The utility model provides a post-printing cutting and conveying device to solve the problem that the loading and unloading of a cutting machine in the prior art requires manual handling.

[0010] The invention has the following beneficial effects: a transport component is arranged at the front end of the cutting component to transport the printed matter to the cutting component; when the cutting component completes cutting of the printed matter, the grabbing component grabs the printed matter and places it on the conveying component; the conveying component transports the cut printed matter away, thereby completing the loading and unloading of the cutting component and replacing manual handling.

[0011] Furthermore, the cutting and conveying device also includes a frame, the transport component is installed on the frame, and the transport component includes an upstream conveyor and a downstream conveyor for successively transporting the printed products.

[0012] Furthermore, the frame is fixedly equipped with a plurality of slide bars arranged at equal intervals, the plurality of slide bars are used to place printed materials, the extension direction of each slide bar is consistent with the moving direction of the printed materials, and an avoidance gap is provided on the frame between two slide bars, and a block is installed on the upstream conveyor, and the block extends from the avoidance gap to above the slide bar, so that the upstream conveyor can push the printed materials to move by driving the block.

[0013] The invention has the following beneficial effects: the upstream conveyor is a belt conveyor, so that the belt of the belt conveyor does not directly contact the printed matter, and the printed matter can be pushed to move only when the stopper moves to a relevant position.

[0014] Furthermore, the frame is arranged at an angle, a moving receiving platform for supporting printed materials is installed at the lower front end of the frame, a micro-vibrator is installed on the moving receiving platform, and an auxiliary connecting plate is installed at the upper front end of the frame.

[0016] Furthermore, a pressing wheel for pressing printed matter is rotatably mounted on the motion receiving platform, and the pressing wheel is provided in plurality.

[0017] The invention has the following beneficial effects: the pressing wheel can effectively prevent the printed product from tilting during the conveying process, which is beneficial for conveying the printed product to the auxiliary push plate.

[0018] Further, the downstream conveyor includes a linear drive assembly and a push plate assembly driven by the linear drive assembly, and the linear drive assembly includes:

[0019] A lead screw is rotatably mounted on the frame, and an extending direction of the lead screw is consistent with a moving direction of the printed matter;

[0025] The invention has the following beneficial effects: by installing a belt conveyor or a chain conveyor upstream of the downstream conveyor, the two devices can rotate back and forth to transport printed materials, thereby reducing the return time and improving the transport efficiency of printed materials; at the same time, because the next process of the present application is a cutting process, the cutting component in this process has a pneumatic slide and a pusher, and the extension direction of the pneumatic slide is perpendicular to the transport direction of the printed materials. When only the belt conveyor or the chain conveyor is used to transport the printed materials, the installation position of the pneumatic slide will affect the transport of the belt conveyor or the chain conveyor, and the belt conveyor or The belt or chain in the chain conveyor will also affect the pusher to push the printed product. Therefore, using only a belt conveyor or a chain conveyor cannot directly transport the printed product to the accurate cutting position. It is also necessary to use a screw device in conjunction to accurately transport the printed product to the cutting position, because the screw can push the printed product to move through the push plate without having to extend into the interior of the cutting component. The present application sets a push plate assembly so that the upstream conveyor and the downstream conveyor can cooperate and sequentially push the printed product to the cutting position, thereby realizing the transfer of printed products between the upstream conveyor and the downstream conveyor.

[0026] Further, the pressing portion is a pressing block fixedly mounted on the upper end of the auxiliary push plate, and the pressing block faces the stop surface; or

[0027] The pressing portion is an adjusting bolt threadedly penetrating the upper end of the auxiliary push plate, and the adjusting bolt is used to press on the stop surface to adjust the distance between the auxiliary push plate and the connecting piece.

[0028] Furthermore, the connecting member includes a connecting plate connected to the linear drive assembly and a hinge block fixedly assembled with the connecting plate, one side of the hinge block has a through groove extending in the up-down direction, the bottom of the through groove extending in the up-down direction is the stopping surface, the auxiliary push plate is hinged in the through groove, and the through groove faces the direction of the upstream conveyor.

[0029] Furthermore, the auxiliary push plate is hinged in the through slot via a hinge shaft, and the axis extension direction of the hinge shaft is perpendicular to the moving direction of the printed matter;

[0030] The distance from the hinge shaft to the lower end surface of the hinge block is smaller than the distance from the hinge shaft to the upper end surface of the hinge block.

[0031] The invention has the following beneficial effects: when the auxiliary push plate rotates around the hinge axis, the rotation distance of the upper end of the auxiliary push plate pressing against the stop surface is short, so that when the auxiliary push plate can push the printed matter, the printed matter is less likely to pass from the lower side of the auxiliary push plate.

[0044] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0045] Various non-limiting embodiments of the present invention are described in detail below. Any number of elements in the accompanying drawings is for illustration and not for limitation, and any naming is only for distinction and does not have any limiting meaning. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other without conflict.

[0046] Example 1

[0047] like Figure 1-Figure 4 As shown, a post-printing cutting and conveying device includes a frame 12, a transport component 27, a cutting component 3, a grabbing component 25, and a conveying component 26. The transport component 27 is used to convey printed materials; the cutting component 3 is used to cut printed materials; the grabbing component 25 is used to grab the cut printed materials; and the conveying component 26 is used to receive the printed materials grabbed by the grabbing component 25 and convey the printed materials out. By arranging the transport component 27 at the front end of the cutting component 3, the transport component 27 is used to convey the printed materials to the cutting component 3. When the cutting component 3 completes the cutting of the printed materials, the grabbing component 25 grabs the printed materials and places them on the conveying component 26. The conveying component 26 transports the cut printed materials away, thereby completing the loading and unloading of the cutting component 3 and replacing manual handling.

[0048] The transport assembly 27 includes an upstream conveyor 1 and a downstream conveyor 2, both of which are mounted on a frame 12. The upstream conveyor 1 is used to transport printed materials. The upstream conveyor 1 is a belt conveyor or a chain conveyor. The belt conveyor has a belt, which is a closed-loop conveyor belt that can rotate around the drive wheel of the belt conveyor. The push plate is driven to move relative to the screw rod. When the belt is used to transport printed materials, there is no time for the push plate to return. Therefore, the use of a belt conveyor can reduce time waste and improve the transportation efficiency of printed materials. The principle that a chain conveyor can save time and improve transportation efficiency is the same as that of a belt conveyor.

[0049] Specifically, a plurality of slide bars 9 arranged at equal intervals are fixedly mounted on the frame 12. The plurality of slide bars 9 are used to place printed products. The extension direction of each slide bar 9 is consistent with the moving direction of the printed products. The frame 12 between two slide bars 9 has an avoidance gap 8. The upstream conveyor 1 in this embodiment is a belt conveyor. A block 11 is installed on the belt of the belt conveyor. The block 11 extends from the avoidance gap 8 to the top of the slide bar 9, so that the belt conveyor can push the printed products to move by driving the block 11. The number of the block 11 is at least one, and the number of the block 11 can also be determined according to the length of the frame 12 or other actual conditions. By setting the slide bar 9 and making the block 11 higher than the slide bar 9, the belt of the belt conveyor will not directly contact the printed products. Only when the block 11 moves to the relevant position can the printed products be pushed to move.

[0050] The frame 12 is arranged at an angle, and a moving receiving platform 4 for supporting printed materials is installed on the lower side of the front end of the frame 12, and a micro-vibrator 5 is installed on the moving receiving platform 4, and an auxiliary connecting plate 7 is installed on the upper side of the front end of the frame 12. Through the inclined arrangement, one side of the printed material slides down and leans on the moving receiving platform 4 by its own weight, and the printed material is corrected by the vibration of the micro-vibrator 5. The auxiliary connecting plate 7 is used to receive the printed material grabbed by the mechanical gripper in the previous process. At the same time, a pressure head 10 is also installed on the moving receiving platform 4, and the pressure head 10 is used to press the printed material placed on the moving receiving platform 4 to prevent the printed material from tilting. At the same time, a pressure wheel 6 for pressing the printed material is rotatably installed on the rear end of the moving receiving platform 4, and the pressure wheel 6 has multiple pressure wheels. The pressure wheel 6 can effectively prevent the printed material from tilting during the transmission process, which is conducive to transmitting the printed material to the auxiliary push plate 17.

[0051] Specifically, the downstream conveyor 2 is used to receive the printed matter transported by the upstream conveyor 1, and the downstream conveyor 2 includes a linear drive component and a push plate component driven by the linear drive component.

[0052] like Figure 5 As shown, the linear drive assembly includes a lead screw 13, a nut 14, a slide rail 18 and a drive motor. The lead screw 13 is rotatably mounted on the frame 12, and the extension direction of the lead screw 13 is consistent with the moving direction of the printed matter. The nut 14 is threadedly mounted on the lead screw 13, and the push plate assembly is fixedly connected to the nut 14 so that the push plate assembly can move simultaneously with the nut 14. The slide rail 18 is fixedly mounted on the frame 12, and the push plate assembly is slidably mounted on the slide rail 18, and the extension direction of the slide rail 18 is consistent with the extension direction of the lead screw 13. The drive motor is mounted on the frame 12, and the drive motor is connected to the lead screw 13 to rotate the lead screw 13, thereby moving the nut 14.

[0053] like Figure 5-Figure 8As shown, the push plate assembly includes a connecting member connected to the nut 14 and an auxiliary push plate 17 hinged to the connecting member. The connecting member is provided with a stop surface 19, which extends in the up and down directions. An adjusting bolt 20 is threaded through the upper end portion of the auxiliary push plate 17. The adjusting bolt 20 is used to press on the stop surface 19 to adjust the distance that the auxiliary push plate 17 presses on the connecting member, and at the same time enables the bottom of the auxiliary push plate 17 to push the printed matter placed downstream of the auxiliary push plate 17.

[0054] The connecting member includes a connecting plate 15 connected to the nut 14, a slider 21, and an articulated block 16 fixedly assembled with the connecting plate 15. The slider 21 is fixedly connected to the connecting plate 15, and the slider 21 is slidably mounted on the slide rail 18. A through slot 23 extending in the up-down direction is provided on one side of the articulated block 16, that is, the through slot 23 penetrates the upper end face and the lower end face of the articulated block 16, and the direction of the side with the through slot 23 is away from the moving direction of the printed product, and the bottom of the through slot 23 extending in the up-down direction is a stopper surface 19, and the direction of the bottom of the slot is away from the moving direction of the printed product, and the auxiliary push plate 17 is hinged in the through slot 23, and the through slot 23 faces the direction of the upstream conveyor 1.

[0055] The auxiliary push plate 17 is hinged in the through slot 23 through a hinge shaft 22, and the axis of the hinge shaft 22 extends in a direction perpendicular to the moving direction of the printed matter. The hinge shaft 22 is located below the adjusting bolt 20, and the vertical distance from the hinge shaft 22 to the lower end surface of the hinge block 16 is smaller than the vertical distance from the hinge shaft 22 to the upper end surface of the hinge block 16. In this way, when the auxiliary push plate 17 rotates around the hinge shaft 22, the rotation distance of the upper end of the auxiliary push plate 17 pressing against the stop surface 19 is short, so that when the auxiliary push plate 17 is able to push the printed matter, the printed matter is less likely to pass through the lower side of the auxiliary push plate 17.

[0056] By installing a belt conveyor or a chain conveyor upstream of the downstream conveyor 2, these two devices can rotate back and forth to transport printed materials, thereby reducing the return time and improving the transportation efficiency of printed materials; at the same time, because the next process of the present application is a cutting process, the cutting component 3 in this process has a pneumatic slide and a pusher, and the extension direction of the pneumatic slide is perpendicular to the transportation direction of the printed materials. When only a belt conveyor or a chain conveyor is used to transport printed materials, the installation position of the pneumatic slide will affect the transportation of the belt conveyor or the chain conveyor, and the belt conveyor or the chain conveyor will also affect the transportation of the printed materials. The belt or chain will also affect the pusher's pushing of the printed product. Therefore, using only a belt conveyor or a chain conveyor cannot directly transport the printed product to the accurate cutting position. It is also necessary to use a screw 13 device in conjunction to accurately transport the printed product to the cutting position, because the screw 13 can push the printed product to move through the push plate without having to extend into the interior of the cutting component 3. The present application sets a push plate assembly so that the upstream conveyor 1 and the downstream conveyor 2 can cooperate and sequentially push the printed product to the cutting position, thereby realizing the transfer of printed products between the upstream conveyor 1 and the downstream conveyor 2.

[0057] The cutting component 3, the grabbing component 25 and the conveying component 26 in this embodiment have a large number of applications in the prior art, and will not be described in detail in this embodiment.

[0058] The working process of this utility model is as follows:

[0059] The mechanical gripper in the previous process places the printed product on the auxiliary receiving plate 7, and then the printed product slides onto the moving receiving table 4. The micro-vibrator 5 vibrates to align the printed product with the moving receiving table 4 to achieve the correction of the printed product. After that, the belt conveyor rotates to drive the block 11 on the belt to push the printed product to move.

[0060] When the belt conveyor transports the printed matter to the position of the auxiliary push plate 17, the upper end of the auxiliary push plate 17 will rotate around the hinge shaft 22 in the direction away from the movement of the printed matter. At this time, the adjustment bolt 20 is away from the stop surface 19, and the lower end of the auxiliary push plate 17 will rotate in the direction of the movement of the printed matter. During the rotation of the lower end of the auxiliary push plate 17, the distance between the lower end of the auxiliary push plate 17 and the upper surface of the slide bar 9 will become farther and farther. Finally, the distance is sufficient to meet the passage of the printed matter.

[0061] When the printed product completely passes through the auxiliary push plate 17, the lead screw 13 starts to rotate, thereby finally driving the auxiliary push plate 17 to start moving in the direction of the printed product. At this time, the auxiliary push plate 17 will push the printed product to move, and the lower end of the auxiliary push plate 17 will press on the side of the printed product. Then, the upper end of the auxiliary push plate 17 will rotate around the hinge shaft 22 in the direction of the printed product. At this time, the adjusting bolt 20 will press on the stop surface 19, which reduces the rotation angle of the auxiliary push plate 17 and the rotation distance of the auxiliary push plate 17, ensuring that the printed product will not pass from the lower side of the auxiliary push plate 17, so that the auxiliary push plate 17 pushes the printed product to move toward the cutting position in the next process cutting component 3. After the cutting component 3 cuts the delivered printed product, the grabbing component 25 grabs the printed product, and then places it on the conveying component 26, and then the conveying component 26 transports the printed product away.

[0062] Example 2

[0063] The difference between this embodiment and the embodiment 1 is that the pressing portion in the embodiment 1 is the adjusting bolt 20, while the pressing portion in this embodiment is the pressing block 24 (such as Fig. 9 As shown in the figure, the pressing block 24 is installed on the upper end of the auxiliary push plate 17, the pressing block 24 is located above the hinge shaft 22, and the pressing block 24 faces the stop surface 19, that is, the pressing block 24 is located between the auxiliary push plate 17 and the stop surface 19, so that the pressing block 24 can be pressed onto the stop surface 19.
