[0037] In order to make the purpose, technical scheme and advantages of the utility model clearer, the embodiments of the utility model will be described in further detail below with reference to the drawings.

[0038] In an embodiment, the die-cutting machine comprises a paper cutting device (not shown in the figure) and a paper collecting device. The paper cutting device is used for cutting paper, and the paper collecting device is used for receiving the paper cut by the paper cutting device and transmitting it to the outside of the equipment for the operator to perform packaging, handling and other operations.

[0039] It should be noted that the paper collecting device of the embodiment includes two kinds, which are high stack paper collecting device (shown in the figure) and counting stack paper collecting device (shown in the figure). As shown in the figure, the high stack paper collecting device is to place a tray 300 on a lifting platform 200, drive the tray 300 upward by the lifting platform 200 to receive the paper 11, and during the stacking of the paper 11, the lifting platform 200 drives the tray 300 to move downward to provide space for continuous stacking of the paper 11. When the paper 11 is stacked on the tray 300 to the extent that it cannot be stacked any more, the lifting platform 200 drives the tray 300 to descend to the ground, and then a hydraulic vehicle or a forklift is used to remove the paper 11 and the tray 300, and then the empty tray 300 is placed on the lifting platform 200 to receive the next stack of paper 11. Figure 1 Figure 2 As shown in the figure, the counting stack paper collecting device 101 comprises a paper receiving frame 400, a conveying platform 410 and an operation platform 420. The paper receiving frame 400 is also connected with the lifting platform 200 to drive the paper receiving frame 400 upward by the lifting platform 200 to receive the paper 11 cut by the paper cutting device, and then the lifting platform 200 drives the paper receiving frame 400 to move downward to transmit the paper 11 to the conveying platform 410. The conveying platform 410 drives to transmit the paper 11 to the operation platform 420 for the operator to perform packaging, handling and other operations. Figure 1

[0040] As shown in the figure, the counting stack paper collecting device 101 comprises a paper receiving frame 400, a conveying platform 410 and an operation platform 420. The paper receiving frame 400 is also connected with the lifting platform 200 to drive the paper receiving frame 400 upward by the lifting platform 200 to receive the paper 11 cut by the paper cutting device, and then the lifting platform 200 drives the paper receiving frame 400 to move downward to transmit the paper 11 to the conveying platform 410. The conveying platform 410 drives to transmit the paper 11 to the operation platform 420 for the operator to perform packaging, handling and other operations. Figure 2

[0041] ​​​The paper receiving device of the embodiment can switch between the high stack paper receiving mode and the count stack paper receiving mode. The switching method is as follows: for example, switching from the high stack paper receiving mode to the count stack paper receiving mode, only need to take off the tray 300 on the lifting platform 200, and install the paper receiving frame 400 on the lifting platform 200, and set the conveying platform 410 and the operation platform 420 accordingly. Conversely, remove the paper receiving frame 400, the conveying platform 410 and the operation platform 420, and put the tray 300 back on the lifting platform 200, so as to complete the switching from the count stack paper receiving mode to the high stack paper receiving mode.

[0042] In the die cutting machine which can switch between the high stack paper receiving mode and the count stack paper receiving mode, in order to improve the efficiency of the high stack paper receiving, the height of the paper stack that can be accommodated by the tray 300 is set to be higher, and the height distance between the tray 300 in the initial state (i.e. not driven to move up by the lifting platform 200) and the paper outlet 10 of the paper cutting device is set to be higher, so that more paper can be received at one time in the high stack paper receiving, and the frequency of outputting the paper stack can be reduced, and the efficiency of the high stack paper receiving is improved.

[0043] However, as Figure 1 and Figure 2 known, the height distance between the tray 300 in the initial state and the paper outlet 10 of the paper cutting device is set to be higher, which means that the height distance between the lifting platform 200 in the initial state and the paper outlet 10 is larger. In the count stack paper receiving mode, in order to facilitate the operator to perform the operation such as packaging and carrying the paper stack output by counting and stacking on the operation platform 420, the height of the operation platform 420 from the ground is unchanged. The lifting platform 200 in the initial state is basically flush with the ground, so it can be said that the height of the operation platform 420 from the lifting platform 200 in the initial state is unchanged. However, the height distance between the lifting platform 200 in the initial state and the paper outlet 10 is larger, that is, the height distance between the operation platform 420 and the paper outlet 10 is larger, and the height distance between the conveying platform 410 at the same height as the operation platform 420 and the paper outlet 10 is also larger. Then the paper receiving frame 400 needs to move downward to a set distance below the conveying platform 410 after moving upward to receive the paper 11, so as to transmit the paper 11 on the paper receiving frame 400 to the conveying platform 410, and then transmit the paper 11 to the operation platform 420 by the conveying platform 410.

[0044] In this process, since the height distance between the conveying platform 410 and the paper outlet 10 is larger, the paper receiving frame 400 needs to move downward by a larger distance to transmit the paper 11 to the conveying platform 410, and correspondingly, needs to move upward by a larger distance to receive the next stack of paper 11. As a result, the distance of the paper receiving frame 400 moving up and down is lengthened, the running cycle time is increased, and the running efficiency of the equipment in the count stack paper receiving mode is reduced.

[0045] Therefore, with reference toFigure 3 The embodiment of the present application provides another die cutting machine. The paper receiving device 500 for counting and stacking includes a paper receiving frame 600, a lifting platform 700, a conveying platform 800 and an operation platform 900. Different from the foregoing embodiment, the embodiment adds the lifting conveying platform 110.

[0046] Specifically, the conveying platform 800 is arranged to be higher, so that the height distance between the conveying platform 800 and the paper outlet 10 of the paper cutting device is smaller, that is, the height of the conveying platform 800 is higher than the height of the operation platform 900, and the lifting conveying platform 110 is arranged between the conveying platform 800 and the operation platform 900, so that the lifting conveying platform 110 moves up and down to connect the conveying platform 800 and the operation platform 900 respectively. That is, the height distance between the conveying platform 800 and the paper outlet 10 of the paper cutting device is reduced under the condition that the height of the operation platform 900 is unchanged, so that the paper receiving frame 600 only needs to move up and down at a distance below the paper outlet 10 of the paper cutting device and the conveying platform 800, thereby not increasing or reducing the distance of the paper receiving frame 600 moving up and down, not increasing or reducing the running cycle time, and maintaining or reducing the running efficiency of the equipment in the counting and stacking mode.

[0047] It should be noted that the distance of the paper receiving frame 600 moving up and down is not increased or reduced, compared with the height of the tray accommodating the paper in the foregoing embodiment which is arranged to be higher without the demand of improving the high stacking paper receiving efficiency. It can be understood that whether the distance of the paper receiving frame 600 moving up and down is increased or reduced depends on the specific height of the conveying platform 800. Correspondingly, whether the running cycle and the running efficiency in the counting and stacking mode are increased or reduced depends on the specific height of the conveying platform 800 and the time for the lifting conveying platform 110 moving up and down and other factors.

[0048] As shown in Figures 3 to 5 , the paper receiving frame 600 is used for receiving the paper 11. Exemplarily, the paper receiving frame 600 includes a plurality of paper receiving rods 601 arranged at intervals, each of which extends along the first direction X, and the plurality of paper receiving rods 601 form a platform for placing the paper 11.

[0049] The lifting platform 700 described above is located below the paper receiving frame 600, and the paper receiving frame 600 is fixed to the lifting platform 700 through the screw 602. The lifting platform 700 drives the paper receiving frame 600 to move up and down along the height direction Z.

[0050] As shown in Figure 3 and Figure 6As shown, the above-mentioned conveying platform 800 extends along a first direction X; the paper receiving rack 600 is used to move along a height direction Z to transfer the paper 11 to the conveying platform 800; the first direction X is perpendicular to the height direction Z. Exemplarily, the conveying platform 800 includes a first platform portion 810 and a second platform portion 820 that are connected, and the second platform portion 820 is used to connect to the lifting conveyor 110. The projection area of ​​the first platform portion 810 in the height direction Z overlaps the projection area of ​​the paper receiving rack 600 in the height direction Z; the paper receiving rack 600 is used to pass through the first platform portion 810 of the conveying platform 800 in the height direction Z to transfer the paper 11 to the first platform portion 810 of the conveying platform 800.

[0051] Specifically, the projection area of ​​the first platform portion 810 in the height direction Z covers the projection area of ​​the paper receiving rack 600 in the height direction Z, and the paper receiving rack 600 must pass through the conveying platform 800 when moving along the height direction Z.

[0052] The conveying platform 800 includes a plurality of first conveyor belts 801 arranged at intervals, each of which extends along the first direction X. The length of the first conveyor belt 801 in the first direction X is greater than the length of the paper receiving rod 601 in the first direction X, thereby forming a first platform portion 810 covering the paper receiving rack 600 and a second platform portion 820 that does not overlap with the projection of the paper receiving rack 600.

[0053] like Figures 3 to 6 As shown, each receiving rod 601 is disposed between two adjacent first conveyor belts 801 ; the second direction Y is perpendicular to the first direction X. That is, as the paper receiving rack 600 moves up and down, each receiving rod 601 passes between two adjacent first conveyor belts 801 . During this downward movement, the paper 11 on the paper receiving rack 600 falls onto the first platform portion 810 of the conveying platform 800 . The multiple first conveyor belts 801 of the conveying platform 800 are driven along the first direction X to transport the paper 11 along the first direction X.

[0054] like Figure 3 、 Figure 6 and Figure 7 As shown, the lifting conveyor 110 extends along the first direction X. The lifting conveyor 110 is disposed at one end of the conveying platform 800 away from the paper receiving rack 600. That is, when the lifting conveyor 110 is flush with the conveying platform 800, the paper 11 on the conveying platform 800 can be transferred to the lifting conveyor 110.

[0055] like Figure 3 、 Figure 7 and Figure 8As shown, the operation platform 900 is arranged at the end of the lifting conveying table 110 away from the conveying platform 800; along the height direction Z, the operation platform 900 is lower than the conveying platform 800. That is, by making the height of the conveying platform 800 higher than the height of the operation platform 900, the height distance between the conveying platform 800 and the paper outlet 10 of the cutting device is reduced, and the distance of the paper receiving frame 600 between the paper outlet 10 of the cutting device and the distance below the conveying platform 800 is also shortened, thereby reducing the running cycle time and reducing the running efficiency of the equipment in the counting and stacking mode.

[0056] As shown, Figure 3 the lifting conveying table 110 moves upward along the height direction Z and can be connected with the conveying platform 800, and the paper 11 on the conveying platform 800 can be transmitted to the lifting conveying table 110.

[0057] As shown, Figure 4 the lifting conveying table 110 moves downward along the height direction Z and can be connected with the operation platform 900, and the paper 11 on the lifting conveying table 110 can be transmitted to the operation platform 900 for the operator to perform packaging, carrying and other operations.

[0058] Referring to Figure 3 and Figure 4 , the lifting table 700 drives the paper receiving frame 600 located thereon to move upward along the height direction Z so that the paper receiving rod 601 thereof passes through the conveying platform 800 and reaches the paper outlet 10, and the paper 11 output by the paper outlet 10 falls onto the paper receiving frame 600, and after the paper receiving frame 600 receives a preset number of papers 11, the lifting table 700 drives the paper receiving frame 600 to move downward, and the paper receiving frame 600 moves to a distance (for example, 5mm to 10mm) below the conveying platform 800, and the paper 11 on the paper receiving frame 600 falls on the first platform part 810 of the conveying platform 800, and then the conveying platform 800 transmits the paper 11 located thereon along the first direction X so that the paper 11 enters the second platform part 820 and approaches the lifting conveying table 110, and when the lifting conveying table 110 is flush with the conveying platform 800 Figure 3 , the paper 11 on the conveying platform 800 is directly transmitted to the lifting conveying table 110, and if the lifting conveying table 110 is not flush with the conveying platform 800, the lifting conveying table 110 moves up and down to adjust to be flush with the conveying platform 800. Then the lifting conveying table 110 moves downward to be flush with the operation platform 900 Figure 4 , and then the paper 11 on the lifting conveying table 110 can be directly transmitted to the operation platform 900 for the operator to perform packaging, carrying and other operations.

[0059] In summary, the embodiment sets the height of the conveying platform 800 higher than the height of the operation platform 900, and sets the lifting conveying table 110 between the conveying platform 800 and the operation platform 900, so that the lifting conveying table 110 moves up and down to connect with the conveying platform 800 and the operation platform 900 respectively. That is, in the case of ensuring the height of the operation platform 900 unchanged, the height distance between the conveying platform 800 and the paper outlet 10 of the cutting device is reduced, so that the paper receiving frame 600 only needs to move up and down at a distance below the paper outlet 10 of the cutting device and the conveying platform 800, thereby not increasing or reducing the distance of the paper receiving frame 600 up and down, not increasing or reducing the running cycle time, and maintaining or reducing the running efficiency of the equipment in the counting stacking mode.

[0060] As shown in Figure 3 and Figure 5 each paper receiving rod 601 is provided with two connecting rods 603 spaced apart along the first direction X, the lower ends of the plurality of connecting rods 603 are connected through the connecting frame 604, and the lower side of the connecting frame 604 is fixed on the lifting table 700 through the screw 602. It can be understood that the connecting frame 604 is always below the conveying platform 800, and it does not need to pass through the conveying platform 800, as long as the paper receiving rod 601 can pass through the conveying platform 800 to realize the needs of moving up to receive the paper 11 and moving down to convey the paper 11.

[0061] In addition, in order to facilitate disassembly of the paper receiving device 500, the lower side of the connecting frame 604 is provided with a brake wheel 605 to move the paper receiving frame 600.

[0062] It can be understood that, as in the foregoing embodiment, the die cutting machine of the embodiment is switched from the counting stacking paper receiving mode to the high stack paper receiving mode by disassembling the paper receiving frame 600, the conveying platform 800, the lifting conveying table 110 and the operation platform 900, and placing the tray back on the lifting table 700, thereby completing the switching from the counting stacking paper receiving mode to the high stack paper receiving mode.

[0063] In some possible embodiments, as shown in Figure 3 and Figure 4 the paper receiving device 500 further comprises a first sensor 121, a second sensor 122 and a third sensor 123. The first sensor 121 is arranged on the side of the second platform part 820 close to the first platform part 810; the first sensor 121 is used to detect whether there is paper 11 on the first platform part 810. That is, the detection range of the first sensor 121 is the first platform part 810, which is used to determine whether the paper receiving frame 600 has conveyed the paper 11 to the first platform part 810.

[0064] The second sensor 122 is arranged on the side of the second platform 820 away from the first platform 810, and is used to detect whether the second platform 820 has the paper 11. That is, the detection range of the second sensor 122 is the second platform 820, which is used to determine whether the paper 11 has been transferred to the second platform 820.

[0065] The third sensor 123 is arranged on the side of the lifting conveyor 110 away from the second platform 820, and is used to detect whether the lifting conveyor 110 has the paper 11. That is, the detection range of the third sensor 123 is the lifting conveyor 110, which is used to determine whether the paper 11 has been transferred to the lifting conveyor 110.

[0066] Specifically, the paper receiving frame 600 is driven by the lifting table 700 to approach the paper outlet 10 of the cutting device, receives the paper, and then moves downward to a position below the first platform 810 of the conveying platform 800 by a certain distance. During the process of the paper receiving frame 600 passing through the first platform 810, the paper 11 located thereon falls on the first platform 810 of the conveying platform 800. The first sensor 121 works to detect that the first platform 810 has the paper 11, which means that the paper receiving frame 600 has completed the task of transferring the paper 11 to the conveying platform 800. Then, the paper receiving frame 600 can move upward to pass through the conveying platform 800, approach the paper outlet 10 of the cutting device, and receive the next stack of paper 11.

[0067] Then, the conveying platform 800 is driven, and the paper 11 located on the first platform 810 starts to move to the second platform 820 and enters the second platform 820. The second sensor 122 detects that the second platform 820 has the paper 11. If the lifting conveyor 110 is flush with the conveying platform 800 at this time, the third sensor 123 detects that the lifting conveyor 110 has no paper 11. Then, the conveying platform 800 and the lifting conveyor 110 are driven at the same time, and the paper 11 on the second platform 820 is transferred to the lifting conveyor 110.

[0068] When the third sensor 123 detects that the lifting conveyor 110 has the paper 11, the lifting conveyor 110 stops driving, and the lifting conveyor 110 starts to descend to be flush with the operation platform 900. The lifting conveyor 110 continues to drive to transfer the paper 11 to the operation platform 900 for the operator to perform packaging, carrying, and other operations. Finally, the lifting conveyor 110 rises to be flush with the conveying platform 800 to prepare for receiving the next stack of paper 11.

[0069] In this embodiment, the first sensor 121, the second sensor 122, and the third sensor 123 are all photoelectric sensors. However, those skilled in the art can understand that in other embodiments, other types of sensors can also be selected, such as microwave sensors.

[0070] In some possible implementation manners, as shown in Figure 3 and Figure 7 shown, the two sides of the second direction Y of the lifting conveying table 110 are provided with side plates 111, the side plates 111 are fixed with air cylinders 112, and sliding rails 113 extending along the height direction Z are arranged. The sliding rails 113 are slidingly connected with sliding blocks 114, the sliding blocks 114 are connected with the lifting conveying table 110, and the air cylinders 112 are used to drive the sliding blocks 114 to move along the height direction Z on the sliding rails 113. That is, the air cylinders 112 are started, the air cylinders 112 drive the sliding blocks 114 to slide up and down on the sliding rails 113, and the sliding blocks 114 drive the lifting conveying table 110 to move up and down in the sliding process, so as to be connected with the conveying platform 800 or the operation platform 900.

[0071] In some possible implementation manners, as shown in Figure 3 and Figure 6 shown, the paper collecting device 500 further includes a first support frame 830, a first brake caster 831, and a support rod 832. The first support frame 830 is arranged below the second platform part 820 of the conveying platform 800, the support rod 832 is arranged below the first platform part 810 of the conveying platform 800, and the support rod 832 is connected with the ground through a screw 834. Exemplarily, the conveying platform 800 is in a rectangular shape, the first platform part 810 and the second platform part 820 are two rectangular areas divided in the length direction (that is, the first direction X) of the conveying platform 800, and the first support frame 830 includes four vertical rods 833 located at four corners of the second platform part 820 to support the second platform part 820. Correspondingly, one end of the first platform part 810 away from the second platform part 820 is provided with two support rods 832 to jointly support the conveying platform 800 with the four vertical rods 833 of the first support frame 830.

[0072] The first brake caster 831 is arranged below the four vertical rods 833 of the first support frame 830, and cooperates with the screw connection of the support rod 832 with the ground to fix the conveying platform 800 at a specific position, so as to avoid movement of the conveying platform 800, and to avoid affecting paper collection by moving away from the lifting conveying table 110 or the paper collecting frame 600.

[0073] Similarly, as shown in Figure 7 , the lower side of the lifting conveying table 110 is also provided with a second support frame 130. Exemplarily, the second support frame 130 is in a rectangular shape and is parallel to the ground. The two sides of the second direction Y of the second support frame 130 are connected with the side plates 111, in other words, the side plates 111 connect the second support frame 130 and the lifting conveying table 110.

[0074] The second support frame 130 is provided with a second brake caster 131 below, so as to fix the lifting conveying table 110 and avoid the lifting conveying table 110 moving away from the conveying platform 800 or the operation platform 900, thereby affecting the paper collecting.

[0075] Correspondingly, as shown in Figure 3 and Figure 8 , the operation platform 900 is also provided with a third support frame 140 below. Exemplarily, the operation platform 900 also has a rectangular shape. Similarly to the first support frame 830, the third support frame 140 also includes four vertical rods 142, which are respectively arranged on the four corners of the operation platform 900, so as to support the operation platform 900 upward.

[0076] The four vertical rods 142 of the third support frame 140 are all provided with a third brake caster 141 below, so as to fix the operation platform 900 and avoid the operation platform 900 moving away from the lifting conveying table 110, thereby affecting the paper collecting.
