Description

Technical Field

[0001] The utility model relates to the technical field of cardboard printing, in particular to a cardboard ejection device for a cardboard printing line. Background Technique

[0002] Cardboard printing is a process of applying images or texts on the surface of cardboard, which is usually used for making packaging, display materials and other printed products.

[0003] As disclosed in a cardboard ejection device for a cardboard green printing line with the authorization publication number CN208663895U, it includes a bottom table. One end of a rotating shaft is movably connected to the middle of the upper end surface of the bottom table, and the other end of the rotating shaft is movably connected to one end of a first piston rod. The other end of the first piston rod is inserted into the interior of one end of a sealed cabin and fixedly connected to one end of a return spring. After adopting the above technical solution, the beneficial effect of the utility model is that air with a relatively fast flow rate enters the air outlet head through the air outlet pipe and is discharged from the air outlet. The fast-flowing air forms a wind force blowing towards the cut cardboard, so that the cut cardboard is subjected to elastic force and at the same time is subjected to wind force in the air, and moves towards the lower conveyor belt direction to complete the displacement.

[0004] Although the above patent can eject the cardboard through wind force, when the weight of the cardboard to be ejected is relatively large, the wind force may not be sufficient to blow the cardboard. Moreover, when the cardboard bounces up, due to the action of its own gravity, the inertia is different, so the rising position is also different. Therefore, the blown wind force may not be concentrated and sprayed on one side of the cardboard to push it. Content of the Utility Model

[0005] The purpose of the utility model is to provide a cardboard ejection device for a cardboard printing line to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution:

[0025] As Figures 1-5 Shown, a technical solution provided by the present utility model:

[0026] A cardboard ejection device for a cardboard printing line, including a platform 1, a fixed block 2 is movably installed at the top end of the platform 1, adjusting blocks 3 are movably installed on both sides of the fixed block 2, a distance adjusting mechanism is arranged outside the platform 1 close to the adjusting blocks 3, the distance adjusting mechanism includes side plates 5, the side plates 5 are symmetrically arranged outside both sides of the platform 1, a mounting seat 6 is arranged in the middle of the upper end of the side plate 5, a cylinder 1 7 is arranged outside the mounting seat 6, the output shaft of the cylinder 1 7 is fixedly connected with a material guiding plate 8, rod sleeves 9 are fixedly installed at the top ends of both sides of the side plate 5, guide rods 10 movably connected with the rod sleeves 9 are arranged on both sides of the back of the material guiding plate 8, the distance adjusting mechanism further includes an inner groove 11, the inner groove 11 is opened in the middle of one side of the adjusting block 3 close to the fixed block 2, a spring 1 12 is arranged at one end inside the inner groove 11, and the other end of the spring 1 12 is movably connected with the fixed block 2 through a connecting rod 13;

[0027] In this embodiment, if the area of ​​the cardboard to be ejected changes, the cylinder 7 outside the mounting seat 6 is controlled to start. After the cylinder 7 is started, the guide plate 8 is controlled to move forward. When the guide plate 8 moves forward, it pushes the adjustment block 3 and compresses the spring 12 inside the inner groove 11. At the same time, the connecting rod 13 moves inward along the inner groove 11. In this way, the distance between the fixed block 2 and the adjustment block 3 is shortened, which is convenient for adapting to smaller cardboards. Conversely, when the guide plate 8 moves in the opposite direction, it can adapt to larger cardboards.

[0028] like Figure 4 and Figure 5 As shown, the hanger 4 is symmetrically arranged on both sides of the bottom end of the middle part of the platform 1, and a power storage mechanism is arranged between the two hangers 4. The power storage mechanism includes a motor 14, and the motor 14 is fixedly installed on the lower outer side of the right hanger 4. A screw 15 is fixedly installed on the output shaft end of the motor 14, and a movable sleeve 16 is movably installed on the outside of the screw 15. A limit rod 17 is fixedly installed between the middle parts of the two hangers 4, and a movable block 18 movably connected to the limit rod 17 is integrally formed at the top of the movable sleeve 16. The movable block A cylinder 2 19 is fixedly installed on the top of the one 18, a positioning block 20 is arranged at the middle bottom of the fixed block 2, and a movable groove 21 movably connected to the positioning block 20 is opened in the middle of the platform 1; an ejection mechanism is arranged below the two sides of the platform 1 close to the fixed block 2, and the ejection mechanism includes a guide groove 22, and a fixed rod 23 is fixedly installed on the inner side of the guide groove 22, and movable blocks 24 are arranged on both sides of the bottom end of the fixed block 2, and a spring 25 is arranged between the movable block 24 and the guide groove 22 located on the outer side of the fixed rod 23;

[0029] In this embodiment, during ejection, cylinder 2 19 is started, and cylinder 2 19 retracts the output shaft from under the positioning block 20. At this time, spring 25 in the guide groove 22 in a force storage state controls the movable block 24 to eject, and the movable block 24 drives the fixed block 2 and the adjusting block 3 to push the cardboard out. At this time, the fixed block 2 and the adjusting block 3 move from one side of the platform 1 to the other side, and the motor 14 is started. The motor 14 controls the rotation of the screw 15. When the screw 15 rotates, it drives the movable sleeve 16 to move linearly, and the cylinder 2 19 is moved to the bottom of the positioning block 20 through the movable block 18, and then the cylinder 2 19 is started, and the output shaft of the cylinder 2 19 is locked under the positioning block 20, and then the movable sleeve 16 is controlled to retract to the initial point, and the spring 25 in the guide groove 22 is compressed and stored, and the next cardboard can be ejected again.

[0030] Working principle: When in use, the cardboard is located in the front position of the fixed block 2 and the adjusting block 3. When ejecting, the cylinder two 19 is started. The cylinder two 19 retracts the output shaft from below the positioning block 20. At this time, the spring two 25 in the guide groove 22 in the energy storage state will control the ejection of the movable block two 24. The movable block two 24 drives the fixed block 2 and the adjusting block 3 to push out the cardboard. At this time, the fixed block 2 and the adjusting block 3 move from one side of the platform 1 to the other side, and the motor 14 is started. The motor 14 controls the rotation of the screw rod 15. When the screw rod 15 rotates, it drives the movable sleeve 16 to move linearly. Through the movable block one 18, the cylinder two 19 is moved below the positioning block 20. Then the cylinder two 19 is started again. The output shaft of the cylinder two 19 is locked below the positioning block 20. Then the movable sleeve 16 is controlled to retract to the initial point, compressing and storing energy the spring two 25 inside the guide groove 22, and then the next cardboard can be ejected again. If the area of the cardboard to be ejected changes, the cylinder one 7 outside the mounting seat 6 is controlled to start. After the cylinder one 7 starts, it controls the feeding guide plate 8 to move forward. When the feeding guide plate 8 moves forward, it pushes the adjusting block 3 and compresses the spring one 12 inside the inner groove 11. At the same time, the connecting rod 13 moves inward along the inner groove 11, so that the distance between the fixed block 2 and the adjusting block 3 is reduced, facilitating the adaptation to cardboard with a smaller volume. On the contrary, when the feeding guide plate 8 moves in the reverse direction, it can adapt to cardboard with a larger volume.
