Description

Technical Field

[0001] The invention relates to the technical field of printing equipment, and in particular to a high-precision positioning mechanism for die-cutting and waste removal. Background Art

[0002] With the development of commodity market demand, more and more merchants begin to pay attention to the outer packaging of commodities, so manufacturers also pay more attention to the production of packaging materials. At present, the outer packaging printing process that has evolved is to put on the plate, adjust the pressure, determine the rules, paste the base material and auxiliary materials, test the die-cutting, formal die-cutting and creasing, clear the waste, roll up the finished product or cut it into pieces, and count and pack it. Then these finished products are sent by the manufacturer to the merchants to package the merchants' commodities.

[0003] It should be noted that die-cutting and waste cleaning are closely related. The cardboard after die-cutting is transferred to the lower waste cleaning board, and the waste on the cardboard after die-cutting is ejected by the upper and lower waste cleaning boards moving in opposite directions, and then collected in the waste collection cabin. For example, the patent document with application number 2021115640725 discloses such a waste cleaning mechanism of a die-cutting machine, which realizes waste cleaning through the above principle, because the upper waste cleaning board is provided with a waste cleaning knife, and the lower waste cleaning board is provided with a waste cleaning hole, and the shapes of the two are consistent, so when the upper and lower waste cleaning boards move in opposite directions, the waste still connected to the cardboard after die-cutting can be ejected.

[0004] However, it should be noted that the upper cleaning frame with the upper cleaning plate and the lower cleaning frame with the lower cleaning plate are controlled independently of each other and are controlled by two independent crankshafts. If the motors driving the two crankshafts are not completely synchronized in controlling the upper cleaning frame and the lower cleaning frame, it may lead to incomplete cleaning of the cardboard. However, because there is a margin of fit between the cleaning knife and the cleaning hole, the equipment can still operate normally, which further increases the pressure of secondary inspection of the cardboard. In addition, the complete primary drive of the upper cleaning frame and the lower cleaning frame requires two crankshafts to rotate one circle, so there is still the problem of low operating efficiency.

DETAILED DESCRIPTION

[0024] The above and other embodiments and advantages of the present invention are described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments.

[0025] In one embodiment, Figure 1-4 shown.

[0026] The die-cutting waste stripping high-precision positioning mechanism provided in this embodiment comprises a relative transmission surface wall panel 1 and an operating surface wall panel 2, wherein an adjacent die-cutting station 3 and a waste stripping station 4 are formed between the transmission surface wall panel 1 and the operating surface wall panel 2, and a pair of upper swing shafts 5 and a pair of lower swing shafts 6 are provided at the waste stripping station 4, and L-shaped upper swing arms 7 are provided at both ends of the upper swing shaft 5, and the lateral driving ends of the two upper swing arms 7 on each side are connected through a horizontal first horizontal connecting rod 8, and the longitudinal driving ends of the two upper swing arms 7 on each side are connected to a corner of an upper waste stripping frame 10 through a vertical first vertical connecting rod 9, and L-shaped lower swing arms are provided at both ends of the lower swing shaft 6. The first and second horizontal connecting rods 8 and 12 on each side are opposite to each other, and a shaft sleeve 15 is rotatably connected to the first horizontal connecting rod 8, and a shaft core 16 extending upward and extending into the shaft sleeve 15 is rotatably connected to the second connecting rod. The end of the shaft core 16 extending into the shaft sleeve 15 is provided with a light collecting cavity 17 along its axial direction, and a laser receiving plate 18 is provided at the bottom of the light collecting cavity 17. A pressure detection plate 19 is provided at the opening of the optical cavity 17. A lower light-transmitting hole 20 is provided on the pressure detection plate 19, which is connected to the sleeve 15 and the light-collecting cavity 17 along the axial direction of the shaft core 16. The sleeve 15 is rotatably connected to the first cross-link rod 8 through a hollow pipe sleeve 21. A tube core 23 is fixedly connected to the first cross-link rod 8, which penetrates the pipe sleeve 21 and extends into the sleeve 15 and has a laser lamp 22 at the end. A stopper 24 is also provided in the sleeve 15. An upper light-transmitting hole 25 is provided on the stopper 24 along the axial direction of the sleeve 15 and opposite to the lower light-transmitting hole 20. The stopper 24 and the pressure detection plate 1 9; the upper swing shaft 5 and the lower swing shaft 6 on one side are connected by a speed matching transmission chain 27, and are synchronously driven by a swing shaft motor 28 coaxially connected to the lower swing shaft 6; wherein the swing shaft motor 28 drives the first cross link 8 and the second cross link 12 to and fro to control the upper waste cleaning frame 10 and the lower waste cleaning frame 14 to approach and separate from each other, and when the upper waste cleaning frame 10 and the lower waste cleaning frame 14 approach each other, the laser receiving board 18 receives the light signal of the laser lamp 22 as an enable signal for the pressure detection board 19 to detect the pressure signal generated by the pressure spring 26 and output it to the controller.

[0027] In this embodiment, the die-cutting waste cleaning high-precision positioning mechanism has higher precision during waste cleaning, so the waste cleaning is more thorough and more efficient. As described in the background technology, the die-cutting waste cleaning mechanism of the traditional printing press is independent of each other in control of the upper waste cleaning frame and the lower waste cleaning frame, that is, two motors independently control two sets of crankshafts. Therefore, even if the control of the upper waste cleaning frame and the lower waste cleaning frame is not completely synchronized, it cannot be fed back immediately. It can only be discovered when it affects the waste cleaning of the cardboard to a certain extent. Even if the two motors are linked and controlled synchronously, the asynchronism between the upper waste cleaning frame and the lower waste cleaning frame is inevitable due to assembly deviation, operation loss, operation displacement and other problems.

[0028] Based on this, the die-cutting waste stripping high-precision positioning mechanism provided in this embodiment uses the swing shaft motor 28 to synchronously drive the upper swing shaft 5 and the lower swing shaft 6. First, different from the traditional driving method, the L-shaped upper swing arm 7 and the lower swing arm 11 are used as transmission parts, and the upper waste stripping frame 10 and the lower waste stripping frame 14 are moved closer to and away from each other by making the first horizontal connecting rod 8 and the second horizontal connecting rod 12 move back and forth in opposite directions. Figure 2 As shown, if the first transverse link 8 moves to the left, the second transverse link 12 moves to the right, so that the upper waste cleaning frame 10 and the lower waste cleaning frame 14 are separated from each other. On the contrary, if the first transverse link 8 moves to the right, the second transverse link 12 moves to the left, so that the upper waste cleaning frame 10 and the lower waste cleaning frame 14 are close to each other. It can be seen that the time period for the upper waste cleaning frame 10 and the lower waste cleaning frame 14 to approach and separate from each other is significantly shorter than the time for the upper swing arm 7 and the lower swing arm 11 to rotate one circle. Therefore, in this respect, more efficient waste cleaning can be achieved.

[0029] Of course, more importantly, the concept of the present embodiment is that when the first cross link 8 and the second cross link 12 move back and forth, the sleeve 15 and the shaft core 16 that are sleeved together move telescopically. And when the upper waste stripping frame 10 and the lower waste stripping frame 14 are close to each other to achieve waste stripping, the position state of the sleeve 15 and the shaft core 16 is as follows: Figure 2 As shown in the figure, it is in an upright state. Of course, this is the ideal operating state at the initial stage of equipment commissioning. As the equipment continues to be put into use, the sleeve 15 and the shaft core 16 may not be in a completely upright state, and even the relative compression stroke of the sleeve 15 and the shaft core 16 may change. Corresponding to the position state of the upper waste cleaning frame 10 and the lower waste cleaning frame 14, the upper waste cleaning frame 10 and the lower waste cleaning frame 14 are misaligned in the left-right direction and in the up-down direction, which will affect the waste cleaning effect. In this embodiment, each time waste cleaning is completed, as shown in FIG. Figure 3As shown, if the sleeve 15 and the shaft core 16 are fully erected, the light emitted by the laser lamp 22 passes through the upper light-transmitting hole 25 and the lower light-transmitting hole 20 and hits the laser receiving plate 18. At the same time, because of the contraction between the sleeve 15 and the shaft core 16, the pressure spring 26 is compressed, which is detected by the pressure detection plate 19 and sent to the controller. It should be noted that the laser receiving plate 18 receives the light signal of the laser lamp 22 as an enable signal for the pressure detection plate 19 to output the pressure signal generated by the pressure spring 26 to the controller. Only when the laser receiving plate 18 receives the light signal, the pressure signal of the pressure detection plate 19 is valid. Therefore, the ideal state is that the controller stably receives a constant value during each waste cleaning action. However, if the upper waste cleaning frame 10 and the lower waste cleaning frame 14 are misaligned in the left-right direction, or in the up-down direction, the first situation will cause the laser receiving plate 18 to be unable to receive the light signal, because the laser lamp 22 is fixed by the tube core 23 fixedly connected to the first horizontal connecting rod 8, and its direction is always downward. Therefore, if the upper waste cleaning frame 10 and the lower waste cleaning frame 14 are misaligned in the left-right direction, that is, the sleeve 15 and the shaft core 16 are tilted, then the laser lamp 22 cannot pass through the upper light-transmitting hole 25 and the lower light-transmitting hole 20, and the controller data is missing. The second situation will cause the data value received by the controller to fluctuate, rather than be constant. Because the extension or contraction between the sleeve 15 and the shaft core 16 occurs, it will be fed back to the pressure detection plate 19 in the form of pressure spring 26 being compressed. Therefore, through the above-mentioned embodiment, when the die-cutting waste cleaning high-precision positioning mechanism is running, the position status of the upper waste cleaning frame 10 and the lower waste cleaning frame 14 can be fed back in real time, thereby achieving higher waste cleaning accuracy. On the control end, the upper swing shaft 5 and the lower swing shaft 6 are synchronously driven by the swing shaft motor 28, and on the execution end, the state of the synchronous drive is fed back in real time by the structure such as the sleeve 15 and the shaft core 16, so that higher waste cleaning accuracy and efficiency are achieved as a whole.

[0030] In one embodiment, Figure 4 shown.

[0031] The die-cutting waste removal high-precision positioning mechanism provided in this embodiment has a mounting hole 29 connected to the hollow part of the tube sleeve 21 on the first horizontal connecting rod 8, and a fixing piece 30 located at the mounting hole 29 is also provided on the first horizontal connecting rod 8, and the tube core 23 is fixedly connected to the fixing piece 30. Preferably, the fixing piece 30 is in a cross ring shape, and a cross slot 31 is provided at the end of the tube core 23 along its axial direction, and the tube core 23 is clamped with the fixing piece 30 through the cross slot 31.

[0032] In this embodiment, a mounting hole 29 is provided on the first cross link 8, and the mounting hole 29 is connected to the hollow part of the tube sleeve 21, so that the tube core 23 can pass through the mounting hole 29 and the hollow part of the tube sleeve 21 to enter the shaft sleeve 15, and the laser lamp 22 is fixed on the tube core 23, and the tube core 23 is fixedly connected to the first cross link 8 through the fixing member 30, so that the laser lamp 22 can be always oriented downward without rotating with the tube sleeve 21. In this embodiment, the cross slot 31 and the cross ring-shaped fixing member 30 are preferably connected, so that the connection structure is firm.

[0033] In one embodiment, Figure 3 shown.

[0034] The die-cutting waste removal high-precision positioning mechanism provided in this embodiment has a limit member 24 in the shape of a thick-walled cylinder, an upper spring groove 32 is provided at the bottom of the limit member 24, and a lower spring groove 33 with the same shape and opposite position as the upper spring groove 32 is provided on the pressure detection plate 19, and the two ends of the pressure spring 26 are respectively located in the upper spring groove 32 and the lower spring groove 33.

[0035] In this embodiment, the pressure spring 26 is fixed by opening an upper spring groove 32 at the bottom of the limiting member 24 and opening a lower spring groove 33 on the pressure detection plate 19 .

[0036] In one embodiment, Figure 5-6 shown.

[0037] The die-cutting waste stripping high-precision positioning mechanism provided in this embodiment has four tension springs 35 for elastically connecting the lower waste stripping plate 34 on the lower waste stripping frame 14, straight racks 36 are provided on both sides of the lower waste stripping frame 14, and a transverse beam 37 is provided between the two sides of the lower waste stripping frame 14. The transverse beam 37 is sleeved on both sides of the lower waste stripping frame 14 through frame parts 38 provided at both ends. A transmission gear 39 meshing with the straight rack 36 is provided inside the frame part 38, and a transverse motor 40 driving the transmission gear 39 is provided outside the frame part 38. An oblique plug-in 41 is provided at the bottom of the lower waste stripping plate 34, and an oblique insertion port 42 is provided on the transverse beam 37 for inserting the oblique plug-in 41 to different degrees during transverse movement; wherein the transverse motor 40 controls the transverse motor 40 to rotate forward and reverse according to the increase or decrease of the pressure signal, thereby causing the transverse beam 37 to move horizontally so that the oblique plug-in 41 is inserted into the oblique insertion port 42 to different degrees.

[0038] In this embodiment, when the traverse motor 40 controls the transmission gear 39 to rotate, the traverse beam 37 can be traversely moved relative to the lower waste stripping frame 14, because the traverse beam 37 is sleeved on both sides of the lower waste stripping frame 14 through the frame parts 38 provided at both ends. If the traverse beam 37 is traversely moved, the oblique plug-in 41 will be inserted into the oblique insertion port 42 to different degrees. Figure 6As shown, if the oblique plug 41 is inserted shallowly into the oblique insertion opening 42, the position of the lower waste stripping plate 34 is moved upwards accordingly, and if the oblique plug 41 is inserted deeply into the oblique insertion opening 42, the position of the lower waste stripping plate 34 is moved downwards accordingly. Therefore, the traverse motor 40 controls the traverse motor 40 to generate forward and reverse rotations according to the increase or decrease of the pressure signal, so that the traverse beam 37 is traversed to allow the oblique plug 41 to be inserted into the oblique insertion opening 42 to different degrees. The misalignment of the upper waste stripping frame 10 and the lower waste stripping frame 14 in the vertical direction can be offset to a certain extent, so as to maintain the high-precision waste stripping of the equipment and reset the constant value used for reference.

[0044] In this embodiment, by providing the first gear 44 and the second gear 45 as transmission parts, the positions of the second gear 45 directly meshing with the spur rack 36 and the power source transverse motor 40 can be staggered to reduce the influence of mechanical vibration on the meshing.
