Description

Technical Field

[0001] This utility model relates to the field of four-color water-based ink printing and die-cutting machine technology, and in particular to a material discharge device for a four-color water-based ink printing and die-cutting machine. Background Technology

[0002] The four-color water-based ink printing and die-cutting machine is a carton packaging equipment that integrates printing, slotting, and die-cutting functions. It is widely used in the processing of three-layer and five-layer corrugated cardboard.

[0003] After the four-color water-based ink printing and die-cutting machine finishes processing, a transport mechanism needs to be set up at the die exit port of the four-color water-based ink printing and die-cutting machine to assist in the output of corrugated paper. Multiple belts are used to transport the corrugated paper. The distance between the multiple belts is not easy to adjust. If the gap between adjacent belts is too large, the transport of corrugated paper will be unstable. If the gap between adjacent belts is too small, the contact area between the belt and the corrugated paper will increase, which will affect the drying of the ink on the corrugated paper after printing.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0047] In the description of this utility model, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified. Furthermore, the terms "installed," "connected," and "linked" should be interpreted broadly; for example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0048] In this embodiment, as Figure 1 and Figure 2 As shown, a discharge device for a four-color water-based ink printing die-cutting machine includes a die-cutting machine body 1. A frame 11 is configured at the die-out end of the die-cutting machine body 1. The discharge device includes: a positioning link 2, with positioning holes evenly distributed around its outer periphery; both ends of the positioning link 2 are connected to the frame 11 via hinges 21; multiple pulleys 22, connected to the positioning holes of the positioning link 2 via positioning pins 221, and evenly distributed along the positioning link 2 at a preset distance; an anti-slip drive shaft 3, connected to the frame 11 via bearings, with a motor 31 installed at its input end; and a conveyor belt 32 connected to the pulleys 22 via the conveyor belt 32.

[0049] The anti-slip drive shaft 3 and the positioning link 2 are located on the same horizontal plane.

[0050] Therefore, the output shaft of motor 31 drives the anti-slip transmission shaft 3 to rotate through the coupling. The anti-slip transmission shaft 3 drives the positioning link 2 to rotate through the conveyor belt 32. At the same time, the pulley 22 rotates together with the positioning link 2. The corrugated paper processed by the die-cutting machine body 1 falls onto the conveyor belt 32 for transportation. According to the size of the corrugated paper, the position of the pulley 22 on the positioning link 2 is adjusted. After the rotating bolt 212 is separated from the positioning link 2, the pulley 22 is moved on the outer periphery of the positioning link 2. The bolt 212 is used to re-fix the position of the positioning link 2, thereby changing the distance between adjacent conveyor belts 32 so that the gap between adjacent conveyor belts 32 can be adapted to corrugated paper of different sizes.

[0051] Specifically, the outer circumference of the positioning link 2 is evenly distributed with multiple positioning holes. The distance between adjacent positioning holes is processed according to the usage requirements. At least four pulleys 22 are designed (the number of pulleys 22 used is added according to the length of the positioning link 2). A through hole for installing positioning pins 221 is opened in the pulley 22. The positioning pins 221 are machined with threads. The outer wall of the anti-slip drive shaft 3 is machined with anti-slip texture. The anti-slip texture is used to prevent the conveyor belt 32 from slipping on the outer circumference of the anti-slip drive shaft 3. The output end of the motor 31 is connected to the anti-slip drive shaft 3 through a coupling. The motor 31 is a servo motor. The number of conveyor belts 32 used is consistent with the number of pulleys 22.

[0052] In some embodiments, such as Figure 3 As shown, the hinge 21 includes: a sliding vertical plate 211, two sliding vertical plates 211 are symmetrically distributed based on the positioning link 2, the sliding vertical plates 211 are rotatably connected to the positioning link 2 through bearings, the bottom end of the sliding vertical plate 211 is inserted into the limiting groove of the frame 11, and the sliding vertical plate 211 is connected to the vertically distributed threaded holes in the limiting groove of the frame 11 through bolts 212.

[0053] Specifically, there are two sliding vertical plates 211. The sliding vertical plates 211 are used to support the positioning link 2. The limiting groove of the frame 11 is long and narrow. Multiple threaded holes are evenly distributed in the limiting groove of the frame 11. There are at least two threaded holes. The bolts 212 are used to fix the position of the sliding vertical plates 211 in the limiting groove of the frame 11.

[0054] It should be noted that by changing the position of the sliding vertical plate 211 in the limiting groove of the frame 11, the feeding height of the conveyor belt 32 can be changed, so that the conveyor belt 32 can be adapted to the discharge port of the die-cutting machine body 1.

[0055] In some embodiments, such as Figure 4 As shown, a material unloading assembly 4 is provided at the end of the frame 11 away from the die-cutting machine body 1. The material unloading assembly 4 is used to buffer the impact force when the material falls.

[0056] The unloading assembly 4 includes: a support 41, which is fixedly connected to the end of the frame 11 away from the die-cutting machine body 1, and has grooves evenly distributed on its upper surface; a mounting base 42, the bottom of which is connected to the support 41 via a sliding member 43; a vertical slide bar 44, the bottom of which is fixedly connected to the mounting base 42, a receiving cylinder 441 inserted into the top of the vertical slide bar 44, and an elastic member 442 sleeved on the outer periphery of the vertical slide bar 44, the elastic member 442 being located between the receiving cylinder 441 and the mounting base 42; and a material carrying plate 45, which is located below the discharge end of the conveyor belt 32, fixedly connected to the receiving cylinder 441, and a rubber buffer pad 451 fixedly connected to the top of the material carrying plate 45; the rubber buffer pad 451 and the material carrying plate 45 are arranged in an L-shape, and the rubber buffer pad 451 is used to buffer the impact force when the material falls.

[0057] Specifically, the mounting base 42 is arranged parallel to the bearing support 41. The mounting base 42 can slide laterally on the bearing support 41. The rubber buffer pad 451 is arranged perpendicularly to the material bearing plate 45 and is L-shaped. The plasticity of the rubber buffer pad 451 is used to buffer the impact force when the material falls, so as to reduce the damage to the edge of the corrugated paper. There are two vertical slide rods 44, which are symmetrically distributed based on the mounting base 42. The storage cylinder 441 has a cavity to store the vertical slide rods 44 during the downward movement of the material bearing plate 45. The elastic potential energy of the elastic element 442 is used to force the material bearing plate 45 to move slowly downward.

[0058] The 451 rubber buffer pad is processed to have a certain thickness and a certain load-bearing capacity;

[0059] Furthermore, during the next process of processing the corrugated paper, as the amount of corrugated paper on the material support plate 45 decreases, the elastic potential energy of the elastic element 442 forces the material support plate 45 to move slowly upward.

[0060] In some embodiments, such as Figure 1 and Figure 4 As shown, the sliding member 43 includes: a first slide rail 431, the bottom ends of both first slide rails 431 are fixedly connected to the bearing support 41; and sliding wheels 432, multiple sliding wheels 432 are respectively arranged at the four corners of the mounting base 42, and the sliding wheels 432 are slidably connected to the first slide rails 431.

[0061] The first slide rail 431 has two sections, and the sliding wheels 432 have four sections distributed at the four corners of the bottom of the mounting base 42. The sliding wheels 432 are slidably connected to the first slide rail 431 to drive the mounting base 42 to move laterally.

[0062] In some embodiments, such as Figure 4 As shown, the mounting base 42 is equipped with a braking element 421, which is used to limit the position of the mounting base 42 on the bearing support 41;

[0063] The braking component 421 includes: a plug plate 421a, which is fixedly connected to the mounting base 42. The plug plate 421a is internally threaded with a plug pin 421b, and the plug plate 421a is connected to the slot of the bearing support 41 through the plug pin 421b.

[0064] Specifically, a slot is machined in the plug plate 421a to match the plug pin 421b, and the plug pin 421b is connected to the slot of the support 41 to fix the position of the mounting base 42 on the support 41.

[0065] In some embodiments, such as Figure 5 As shown, the bearing support 41 is equipped with a compensation component 5, which is used to extend the service length of the bearing support 41.

[0066] The compensation component 5 includes: a compensation plate 51, which is connected to the bearing support 41 via a fastener 52; and a second slide rail 53, which is located on the upper surface of the compensation plate 51 and is adapted to the first slide rail 431.

[0067] Specifically, the second slide rail 53 on the compensation plate 51 is adapted to the first slide rail 431, and the compensation plate 51 can be connected end to end for use.

[0068] In some embodiments, such as Figure 5 As shown, the fastener 52 includes a strip plate 521, which is adapted to the strip groove on the side of the bearing support 41, and the strip plate 521 is connected to the bearing support 41 by a threaded pin 522.

[0069] The compensation plate 51 has a strip plate 521 on one side and a connecting groove adapted to the strip plate 521 on the other side. The strip plate 521 is connected to the bearing support 41 by a threaded pin 522. Grooves adapted to the strip plate 521 are symmetrically machined on both sides of the bearing support 41.

[0070] In some embodiments, such as Figure 5 As shown, the side of the compensation plate 51 away from the strip plate 521 has a connecting groove that is compatible with the strip plate 521.

[0071] The design of the connecting groove on the side of the compensation plate 51 away from the strip plate 521 facilitates the connection of the compensation plate 51 end to end for use, thereby extending the service length of the first slide rail 431 and making it easier to transport the collected corrugated paper to the vicinity of the equipment in the next process.

[0072] In some embodiments, such as Figure 4 As shown, a handwheel is provided at the top of the plug pin 421b, which is used to rotate the plug pin 421b in the position of use in the plug plate 421a.

[0073] The handwheel at the top of the pin 421b is used to rotate the pin 421b into the slot of the support 41.

[0074] In some embodiments, such as Figure 1 As shown, the elastic element 442 is a compression spring.

[0075] The elastic element 442 adopts a compression spring design to facilitate the reset of the material carrying plate 45.

[0076] The working principle of this application is illustrated below with a preferred embodiment:

[0077] First, connect the compensation plate 51 to the support 41. Insert the strip plate 521 into the strip groove of the support 41. Use the threaded pin 522 to connect the strip plate 521 to the support 41. Then, the second slide rail 53 matches the first slide rail 431. (Multiple compensation plates 51 can be connected end to end according to the usage position of the equipment in the next process to assist in the later transportation of corrugated paper.) Then, move the mounting base 42 to the first slide rail 431 through the sliding wheel 432. Adjust the position of the mounting base 42 below the conveyor belt 32. Rotate the insertion pin 421b in the insertion plate 421a. The insertion pin 421b is inserted into the slot of the support 41 to fix the position of the mounting base 42.

[0078] Then, the external power supply of motor 31 is connected, and motor 31 starts to work. The output shaft of motor 31 drives the anti-slip transmission shaft 3 to rotate through the coupling. The anti-slip transmission shaft 3 is driven by the conveyor belt 32, and the positioning link 2 rotates in the two sliding vertical plates 211. At the same time, the pulley 22 rotates together with the positioning link 2. The corrugated paper processed by the die-cutting machine body 1 falls on the conveyor belt 32 for transportation. The falling corrugated paper hits the rubber buffer pad 451 and continuously accumulates on the material carrying plate 45. As the corrugated paper accumulates, the material carrying plate 45 moves downward under the action of gravity. At the same time, the material carrying plate 45 drives the collection cylinder 441 to move along the vertical slide bar 44 to compress the elastic element 442. After the corrugated paper is collected, the mounting base 42 is pushed to move. The mounting base 42 moves in the first slide rail 431 through the sliding wheel 432, and the sliding wheel 432 can move along the second slide rail 53 to the position of the next process.

[0079] According to the size of the corrugated paper, the position of the pulley 22 on the positioning link 2 is adjusted. First, the bolt 212 is rotated to separate it from the positioning link 2. The pulley 22 is moved around the outer periphery of the positioning link 2 and then re-fixed with the bolt 212. This changes the distance between adjacent conveyor belts 32 so that the gap between adjacent conveyor belts 32 can be adapted to corrugated paper of different sizes. The position of the sliding vertical plate 211 is adjusted vertically in the limiting groove of the frame 11. The position of the sliding vertical plate 211 is fixed with the bolt 212. The positioning link 2 and the anti-slip transmission shaft 3 can be set at an angle so that the positioning link 2 is adapted to the height of the discharge port of the die-cutting machine body 1.

[0080] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
