Detailed Implementation

[0026] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0027] like Figures 1-3 As shown, the present invention discloses a left-right pushing mechanism for collecting sheet printed materials, comprising two mounting plates 1, which are mounted opposite each other. Each mounting plate 1 has a pushing mechanism on one side opposite to the other. The pushing mechanism includes a slide rod 11 slidably connected to the mounting plate 1. The mounting plate 1 is provided with a cylinder 12 connected to the slide rod 11. A baffle 121 is provided on the outer surface of the slide rod 11. A fixed plate 13 is provided on the side of the baffle 121 away from the mounting plate 1. A groove 14 is provided on the middle side of the fixed plate 13. A push plate 15 is slidably mounted in the groove 14. A pressing mechanism is provided between the push plate 15 and the fixed plate 13. The pressing mechanism can maintain downward pressure on the push plate 15 at all times. The baffle 121 is provided with a height lifting mechanism for raising the push plate 15.

[0028] The two installation plates 1 are installed at the discharge port position after the printed matter is printed, and the two side baffles 121 are arranged opposite to each other on the upper side of the discharge conveying belt. The printed matter is moved out from the discharge port and falls between the two baffles 121 and on the upper side of the discharge conveying belt. At this time, the printed matter is stacked on the upper side of the discharge conveying belt. The cylinders 12 of the two side pushing mechanisms start to stretch and contract at the same time, so that the two side sliding rods 11 can drive the two side baffles 121 to move away from each other or move close to each other. Such a design can drive the two side baffles 121 to slide to the left and slide to the right at the same time. The two side baffles 121 can drive the front fixed plate 13 and the push plate 15 to move. Therefore, the front fixed plate 13 and the push plate 15 can be in extrusion contact with the side surface of the printed matter, so as to flatten the side surface of the printed matter stack and ensure that the printed matter stack is in an orderly state.

[0029] During the left-right pushing process of the two side baffles 121, the discharge conveying belt can gradually move downward as the printed matter stack becomes higher and higher. Since the downward pressing mechanism continuously works, the downward pressure of the push plate 15 is always maintained. Therefore, the lower end of the push plate 15 is always in contact with the discharge conveying belt. Therefore, even if the discharge conveying belt is always moving downward, the lower side of the push plate 15 can still flatten the side surface of the lower part of the printed matter stack, and the flatness of the side surface of the printed matter stack can still be maintained. Such a design can completely flatten the side surface of the printed matter stack under the pushing action of the baffles 121 each time.

[0030] When the stacking of the printed matter is completed and does not need to be flattened, the push plate 15 is simultaneously moved upward by the height lifting mechanism on both sides. When the push plate 15 is moved upward and reset, the downward pressing mechanism is retracted until the lower end of the push plate 15 is flush with the lower end of the fixed plate 13. After the printed matter is moved out by the discharge conveying belt, the discharge conveying belt is moved upward again. The lower end of the push plate 15 is in contact with the lower end surface of the discharge conveying belt, so that the next round of flattening of the printed matter stack can be performed again.

[0031] The downward pressing mechanism comprises two limiting grooves 2 arranged on the left and right sides of the chute 14. Two limiting rods 21 are arranged in the two limiting grooves 2. A sliding block 22 connected with the push plate 15 is slidably arranged on the outer surface of each limiting rod 21. A spring 23 is arranged on the upper side of each sliding block 22 and surrounds the outer side of the limiting rod 21.

[0032] Under the action of the spring 23 stretching, the time keeps the downward pressure on the slider 22, because the slider 22 is connected with the push plate 15, so the downward pressure on the push plate 15 can be kept at all times, the lower end surface of the push plate 15 is in contact with the discharge conveying belt, so in the process of the discharge conveying belt moving downward, the push plate 15 is also constantly driven to move downward under the action of the spring 23 stretching, when the height lifting mechanism drives the push plate 15 to move upward, the spring 23 is compressed through the two side sliders 22.

[0033] The lower end of the push plate 15 is provided with a fixed block 24 on both sides, and the two fixed blocks 24 are rotatably connected with a roller 25.

[0034] The lower end of the push plate 15 is in contact with the discharge conveying belt through the roller 25, so when the push plate 15 slides left and right during the process, the roller 25 rolls in contact with the discharge conveying belt, which can reduce the friction between the push plate 15 and the discharge conveying belt, and protect the discharge conveying belt and the push plate 15.

[0035] The height lifting mechanism comprises a support plate 3 arranged on the rear side of the baffle 121, and the support plate 3 is provided with a motor 31 on one side. The output shaft of the motor 31 penetrates through the support plate 3 and is assembled with a winding wheel 32. The outer surface of the winding wheel 32 is fixedly connected with a connecting line 33, and the connecting line 33 passes through the baffle 121 from the upper side and is connected with the upper side of the push plate 15. When it is needed to drive the push plate 15 to move upward, the motor 31 starts to work and drives the winding wheel 32 to start rotating. The winding wheel 32 can wind the connecting line 33, and the connecting line 33 can drive the push plate 15 to move upward from the upper side. When the discharge conveying belt contacts the lower side of the push plate 15 again, the motor 31 stops working. In the process of the push plate 15 moving downward, the connecting line 33 is pulled out of the winding wheel 32, driving the winding wheel 32 to rotate.

[0036] The upper side of the baffle 121 is provided with a guide wheel 34, and the connecting line 33 passes through the upper side of the guide wheel 34.

[0037] The design of the guide wheel 34 can guide the connecting line 33 and prevent hard contact between the connecting line 33 and the baffle 121.

[0038] The same push mechanism is provided with an adjusting assembly between the slide rod 11 and the baffle 121. The adjusting assembly comprises a sleeve 4 embedded in the baffle 121, the sleeve 4 is slidingly assembled on the outer side of the slide rod 11, and the sleeve 4 is threadedly connected with a threaded part 41 which can abut against the slide rod 11.

[0039] The baffle 121 can be adjusted in position relative to the slide rod 11, so the position of the baffle 121 can be adjusted according to the size of the printed matter. After adjusting the baffle 121 to the appropriate position, the worker can tighten the threaded part 41 to fix the sleeve 4 on the outer surface of the slide rod 11.

[0040] The two baffles 121 are respectively sleeved on the outer surface of the slide rod 11 of the other pushing mechanism.

[0041] The two mounting plates 1 are respectively provided with support blocks 42, and the support blocks 42 are assembled with screws 43. The support blocks 42 can be installed at the position of the printed matter discharge port through the design that the screws 43 pass through the support blocks 42.

[0042] The above embodiments only exemplarily illustrate the principle and effect of the present application, and are not used to limit the present application. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of the present application. Therefore, all equivalent modifications or changes completed by those skilled in the art without departing from the spirit and technical thought of the present application should be covered by the claims of the present application.
