Description

Technical fields:

[0001] This utility model relates to the field of cardboard processing technology, and more specifically to a cardboard processing output rack flipping device. Background technology:

[0002] Existing cardboard processing equipment can bend cardboard during transport and nail it at the corresponding positions;

[0003] When nailing, the cardboard needs to be limited in position before it can be output.

[0004] Therefore, a baffle is installed at the output device to block the conveyed cardboard. The existing baffle is driven and lifted by a cylinder. The baffle has a lifting structure. When it is running, when the subsequent cardboard is conveyed, the baffle will drop when the cardboard is pressed against it, which will cause the front end of the cardboard to rub and wear, affecting the processing quality. Utility Model Content:

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a paperboard processing output flipping device. It uses a decelerated rotary servo motor to make the vertical blocking plate of the upper flipping blocking frame flip forward, which facilitates the normal forward horizontal conveying of subsequent paperboard. It will not cause wear and tear on the front end of the conveyed paperboard, thus ensuring the normal conveying and processing quality of the paperboard.

[0006] The solution of this utility model to the aforementioned technical problem is:

[0007] A paperboard processing output feeder flipping device includes a feeder, which includes two side frames, left and right. A middle transverse beam is fixed in the middle between the two side frames. A lower transverse frame is fixed between the lower parts of the two side frames. Side fixing plates are fixed on both sides of the middle fixing plate of the lower transverse frame. A lower drive roller is movably connected to the two side fixing plates through bearings. Upper connecting seats are fixed on the left and right sides of the middle of the rear wall of the middle transverse beam. An upper drive roller is movably connected to the two upper connecting seats through bearings. Guide rubber wheels are fixed on the middle outer walls of the upper and lower drive rollers. The upper guide rubber wheels and the lower guide rubber wheels correspond to each other vertically.

[0008] A lower support frame is fixed to the top surface of the middle fixed plate. A speed-reducing rotary servo motor is fixed to the outer wall of the vertical plate on one side of the lower support frame. The end of the output shaft of the speed-reducing rotary servo motor extends out of the inner wall of the corresponding vertical plate of the lower support frame and is fixed with a circular rotating wheel. The edge of the circular rotating wheel is movably connected to a vertical push rod assembly through a hinge shaft. The top of the vertical push rod assembly is movably connected to an upper flip-blocking frame through a hinge shaft. The upper flip-blocking frame is movably connected to the upper part of the vertical plate through a hinge shaft. The vertical blocking plate of the upper flip-blocking frame is located in front of the middle of the upper and lower transmission rollers and blocks the cardboard conveyed between the guide rollers of the upper and lower transmission rollers.

[0009] The lower support frame includes a fixed base plate, which is fixed to the top surface of the middle fixed plate. Two vertical plates are fixed to the middle of the top surface of the fixed base plate, and a speed-reducing rotary servo motor is fixed to the outer wall of one of the vertical plates.

[0010] The vertical push rod assembly includes an upper movable connector and a lower movable connector. The two ends of the intermediate adjusting screw are screwed into the screw hole in the middle of the bottom end face of the upper movable connector and the screw hole formed in the middle of the top face of the lower movable connector.

[0011] The outstanding effect of this utility model is:

[0012] It operates via a speed-reducing rotary servo motor, which enables the vertical blocking plate of the upper flipping blocking frame to flip forward, facilitating the normal forward horizontal conveying of subsequent cardboard. This prevents wear and tear on the front end of the conveyed cardboard, ensuring normal conveying and processing quality.

[0013] Furthermore, by rotating the central adjusting screw, the length of the vertical push rod assembly can be changed, thereby altering the flipping angle of the upper flipping blocking frame. This angle can be adjusted at will to ensure the flatness of the carton formation and prevent wear on the front end of the conveyed cardboard, thus ensuring the normal conveying and processing quality of the cardboard.

[0020] For example, see below. Figures 1 to 6 As shown, a paperboard processing output feeder flipping device includes a feeder 10, which includes two side frames, left and right. A middle transverse beam 11 is fixed in the middle between the two side frames. A lower transverse frame 12 is fixed between the lower parts of the two side frames. Side fixing plates are fixed on both sides of the middle fixing plate of the lower transverse frame 12. A lower drive roller 13 is movably connected to the two side fixing plates via bearings. Upper connecting seats are fixed on the left and right sides of the middle of the rear wall of the middle transverse beam 11. An upper drive roller 14 is movably connected to the two upper connecting seats via bearings. Guide rollers 15 are fixed on the outer walls of the middle of the upper drive roller 14 and the lower drive roller 13. Wheel 15 and the lower guide wheel 15 are vertically aligned; a rear conveyor shaft is movably connected between the front parts of the two side fixed plates via bearings; a forward extension arm is fixed to the front end of the front part of the two side fixed plates; both ends of the front conveyor shaft are movably connected to the front ends of the two forward extension arms via bearings; multiple rubber wheels are fixed on both the rear and front conveyor shafts; corresponding conveyor belts are tensioned on the two corresponding rubber wheels; a drive sprocket is fixed to one side of the rear conveyor shaft; a conveyor drive motor is fixed to the top surface of the middle fixed plate; a drive sprocket is fixed to the output shaft of the conveyor drive motor; the chain is tensioned on the drive sprocket and the drive sprocket; all conveyor belts can be moved by the operation of the conveyor drive motor.

[0021] Furthermore, a lower support frame 20 is fixed to the top surface of the middle fixed plate. A reduction rotary servo motor 21 is fixed to the outer wall of the vertical plate on one side of the lower support frame 20. The end of the output shaft of the reduction rotary servo motor 21 extends out of the inner wall of the corresponding vertical plate of the lower support frame 20 and is fixed with a circular rotating wheel 22. The edge of the circular rotating wheel 22 is movably connected to a vertical push rod assembly 30 through a hinge shaft. The top of the vertical push rod assembly 30 is movably connected to an upper flipping blocking frame 40 through a hinge shaft. The upper flipping blocking frame 40 is movably connected to the upper part of the vertical plate through a hinge shaft. The vertical blocking plate 41 of the upper flipping blocking frame 40 is located in front of the middle of the upper transmission roller 14 and the lower transmission roller 13 and blocks the cardboard conveyed between the guide rubber wheels 15 of the upper transmission roller 14 and the lower transmission roller 13.

[0022] Furthermore, the lower support frame 20 includes a fixed base plate, which is fixed to the top surface of the middle fixed plate. Two vertical plates are fixed to the middle of the top surface of the fixed base plate, and a speed-reducing rotary servo motor 21 is fixed to the outer wall of one of the vertical plates.

[0023] Furthermore, the upper flip-up blocking frame 40 includes a front connecting block 42, on the rear wall of the front connecting block 42, a vertical blocking plate 41 is fixed, the front connecting block 42 is located between the upper parts of the two vertical plates, and is movably connected to the two vertical plates through a hinge shaft;

[0024] A front connecting plate is fixed on the front wall of the vertical blocking plate 41 above the front connecting block 42;

[0025] The top of the vertical push rod assembly 30 is movably connected to the front connecting plate via a hinge shaft.

[0026] Furthermore, the vertical push rod assembly 30 includes an upper movable connector 31 and a lower movable connector 32. The two ends of the intermediate adjusting screw 33 are screwed into the threaded holes formed in the middle of the bottom end face of the upper movable connector 31 and the top surface of the lower movable connector 33. By rotating the intermediate adjusting screw 33, the distance between its two ends extending into the upper movable connector 31 or the lower movable connector 32 can be changed, altering the overall height of the vertical push rod assembly 30. This allows the change of the initial and flipped states of the vertical blocking plate 41 of the upper flipping blocking frame 40, i.e., the tilt state of the vertical blocking plate 41 in its initial and flipped states. Generally, in the initial state, the vertical blocking plate 41 is vertical; in the flipped state, the vertical blocking plate 41 is horizontal. That is, by rotating the intermediate adjusting screw 33, the tilt angle of the vertical blocking plate 41 of the upper flipping blocking frame 40 in its initial state can be changed. The angle can be adjusted at will to ensure the flatness of the carton forming and to prevent wear on the front end of the conveyed cardboard, thus ensuring the normal conveying and processing quality of the cardboard.

[0027] Furthermore, an intermediate connecting plate is fixed between the middle of the two vertical plates of the lower support frame 20.

[0028] Furthermore, a rear adjustable support cylinder 50 is fixed to the top surface of the middle fixing plate at the rear of the lower support frame 20. An internal thread is formed on the inner side wall of the rear adjustable support cylinder 50. An adjusting stud 51 is screwed onto the internal thread of the rear adjustable support cylinder 50. The top of the adjusting stud 51 extends out of the top of the rear adjustable support cylinder 50 and is fixed to an intermediate guide support plate 52. The top surface of the intermediate guide support plate 52 corresponds to the bottom nailing template 1 of the nail head device installed in the middle of the front wall of the intermediate transverse beam 11.

[0029] Before use, the height of the intermediate guide support plate 52 can be changed by rotating the adjusting stud 51. After adjustment, the nail head device in this embodiment is a conventional structure, which will not be described in detail here.

[0030] In this embodiment, when the cardboard is conveyed from back to front, it will be output between the guide rollers 15 of the upper drive roller 14 and the lower drive roller 13. During operation, whenever the cardboard is conveyed, the vertical blocking plate 41 of the upper flipping blocking frame 40 is set vertically to block the cardboard from being output forward. At this time, the nail head device is operated to make the bottom nailing template 1 descend and nail the cardboard. After completion, the control host controls the deceleration rotary servo motor 21 to run, and the circular rotating wheel 22 rotates to make the upper flipping blocking frame 40 flip forward, and its vertical blocking plate 41 is in a horizontal state, so that the cardboard can be output along the top surface of the vertical blocking plate 41.

[0031] After the output is completed, the deceleration rotary servo motor 21 continues to run, so that the vertical blocking plate 41 returns to a vertical position. Since the cardboard is conveyed and positioned very quickly, the operation of the deceleration rotary servo motor 21 can be controlled. By controlling the operation of the deceleration rotary servo motor 21, it can be ensured that the upper flipping blocking frame 40 flips back to its original position while running continuously for a long time, and the cardboard is continuously limited and placed and conveyed, so as to realize the normal nailing and conveying of the cardboard. Its use effect is good.

[0032] The above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present utility model.
