[0002] The feeder head, also called the paper feeding head, is installed at one end of the printing press, and then the used paper is stacked at one end of the printing press and placed under the feeder head. By operating the feeder head, the paper stacked at one end of the printing press is sent to the conveyor belt, and is transported to the printing press through the conveyor belt to complete the subsequent printing process. In the prior art, a feeder head pressing structure that moves in a curve is set in the feeder head to press and fix the paper, so as to avoid the stacked paper moving below when the suction cup sucks up the paper and transports it, resulting in the stacked paper being tangled. When the feeder head pressing structure in the prior art is used to press the paper, there will be a collision with the stacked paper during pressing, resulting in the paper moved by the suction cup driving the stacked paper into the conveying mechanism to move to the next process, resulting in problems with equipment operation, thereby resulting in a technical problem of low production efficiency. Summary of the invention

[0009] Preferably, a semi-arc connecting portion is provided at one end of the swing arm connected to the first rotating connecting member, the arc-shaped opening of the semi-arc connecting portion faces the first rotating connecting member and the second rotating connecting member, and the free end of the semi-arc connecting portion is rotatably connected to the connecting portion of the first rotating connecting member, and the connecting portion of the second rotating connecting member is rotatably connected to the arc segment of the semi-arc connecting portion.

[0010] Preferably, a vertical connection portion is provided at the other end of the swing arm, one end of the vertical connection portion is fixedly connected to one end of the semi-arc connection portion, and the other end of the vertical connection portion is adjustably connected to the pressure rod.

[0011] Preferably, the ratio between the first rotating connector and the second rotating connector is (9-11):(22-24).

[0012] Preferably, the free end of the pressure rod is bent toward the arc-shaped opening direction of the semi-arc-shaped connecting portion.

[0013] The above one or more technical solutions in the feeder head provided by the embodiment of the present invention have at least one of the following technical effects:

[0014] The feeder head pressing structure in the present invention includes a mounting plate, a first rotating connection member, a second rotating connection member, a swing arm, a pressure rod and a first driving gas rod. The first rotating shaft set at one end of the first rotating connection member is rotatably connected to the mounting plate, and the other end is pivotally connected to the upper end of the swing arm. The second rotating shaft set at one end of the second rotating connection member is rotatably connected to the mounting plate, and the other end is pivotally connected to the swing arm. The output end of the first driving gas rod drives the second rotating shaft to rotate, and the second rotating connection member drives the swing arm to move around the second rotating shaft. Under the restriction of the first rotating connection member, the swing arm is first translated upward for a distance, and then rotated around the first rotating connection member at the upper end of the swing arm. The movement of the swing arm drives the pressure rod set below the swing arm to move, completing the pressing operation of the paper. Through the above arrangement, the movement path of the pressure rod pressing the paper is divided into two processes: lifting and curved swinging, avoiding the problem of directly inserting into the paper gap to press the paper and ejecting the top layer of paper, resulting in low production efficiency.

[0015] Another technical solution of the present invention is a flying head, including the above-mentioned flying head pressing structure; also including a mounting shell, a transverse moving slide rail, a suction cup assembly and a second driving gas rod, the mounting plate is mounted on the mounting shell, the first rotating connecting member, the second rotating connecting member, the swing arm and the pressure rod are all located between the mounting plate and the mounting shell, one end of the transverse moving slide rail is fixedly mounted between the mounting plate and the mounting shell, and the other end of the transverse moving slide rail extends outward, the suction cup assembly is slidably mounted below the transverse moving slide rail, and the suction cup assembly is adjacent to the mounting shell, the second driving gas rod is mounted on the mounting plate, and the second driving gas rod is located above the first driving gas rod, and the output end of the second driving gas rod is connected to the suction cup assembly.

[0016] The above one or more technical solutions in the feeder head provided by the embodiment of the present invention have at least one of the following technical effects:

[0017] The lifting of the ...

[0018] The first rotating connection piece and the second rotating connection piece are respectively rotatably connected with the free end and the middle part of the semi-arc connecting part on the swing arm to limit the running trajectory of the connecting rod. One end of the rotating shaft of the second rotating connection piece passes through the inner wall of the mounting shell and is rotatably connected with the output end of the first driving gas rod through an adapter. The output end of the first driving gas rod drives the adapter piece to make a curved motion around the second rotating connection piece, driving the second rotating connection piece to rotate. At the same time, the connecting part of the first rotating connection piece is shorter than the connecting part of the second connecting part. After the second rotating connection piece rotates, the connecting rod is pushed upward to make the connecting rod move obliquely upward by one end. Then, due to the rotation connection with the first rotating connection piece, the connecting part of the first rotating connection piece is pushed to start a circular motion around the rotating shaft of the first rotating connection piece, pulling the end of the connecting rod to move, and the connecting part of the second rotating connection piece rotates around the rotating shaft of the second rotating connection piece, pulling the connecting rod to continue to move obliquely upward. At the same time, under the traction of the connecting part of the first rotating connection piece, the pressure rod at the other end starts to make a curved motion, thereby realizing that the movement trajectory of the pressure rod is divided into oblique upward translation movement and curved movement. Through the above arrangement, when the suction cup assembly sucks the paper and moves upward, the pressure rod first moves through a curve to reach above the edge of the paper, and then presses the paper by moving downward, thereby avoiding directly inserting into the gap between the papers to press the paper and causing the top layer of paper to be pushed out, affecting subsequent workstations and resulting in low production efficiency.

For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0039] In one embodiment of the present invention, Figures 1 to 6 and Fig. 9 As shown, a flyer head is provided, including a mounting plate 12, a first rotating connecting member 51, a second rotating connecting member 52, a swing arm 54, a pressure rod 55 and a first driving gas rod 53, one end of the first rotating connecting member 51 is provided with a first rotating shaft connected to the mounting plate 12, and the other end of the first rotating connecting member is pivotally connected to the upper end of the swing arm 54; one end of the second rotating connecting member 52 is fixedly provided with a second rotating shaft rotatably connected to the mounting plate 12, and the other end of the second rotating connecting member is pivotally connected to the swing arm 54; the first driving gas rod 53 is arranged on the mounting plate 12, and the first driving gas rod 53 drives the second rotating shaft to rotate, so that the swing arm 54 swings around the first rotating shaft and the second rotating shaft; the pressure rod 55 is arranged at the lower end of the swing arm 54.

[0040] The feeder head pressing structure 50 in the present invention comprises a mounting plate 12, a first rotating connection member 51, a second rotating connection member 52, a swing arm 54, a pressure rod 55 and a first driving air rod 53. The first rotating shaft arranged at one end of the first rotating connection member 51 is rotatably connected to the mounting plate 12, and the other end is pivotally connected to the upper end of the swing arm 54. The second rotating shaft arranged at one end of the second rotating connection member 52 is rotatably connected to the mounting plate 12, and the other end is pivotally connected to the swing arm 54. The output end of the first driving air rod 53 drives the second rotating shaft to rotate, and the second rotating connection member 52 drives the swing arm 54 to move around the second rotating shaft. Under the restriction of the first rotating connection member 51, the swing arm 54 is first translated obliquely upward for a distance, and then rotates around the first rotating connection member 51 at the upper end of the swing arm 54. The movement of the swing arm 54 drives the pressure rod 55 arranged below the swing arm 54 to move, thereby completing the pressing operation on the paper, and at the same time avoiding direct insertion and pressing of the paper pile to cause conflict with the paper pile, disrupting the paper pile, and pushing the conflicting paper to move. Through the above arrangement, the movement path of the pressing rod 55 pressing the paper is divided into two processes: lifting and curved swinging, thereby avoiding the problem of directly inserting into the paper gap to press the paper and pushing out the top layer of paper, resulting in low production efficiency.

[0041] In another embodiment of the present invention, Figures 1 to 9 As shown, a paper pressing head 551 is provided at the end of the pressing rod 55, one end of the paper pressing head 551 is fixedly mounted at the end of the pressing rod 55, and the bottom of the paper pressing head 551 is set as a plane, and the free end of the paper pressing head 551 is provided with an insertion end for inserting into the paper gap, the bottom of the insertion end is set horizontally, and the cross-section of the front end is set at an acute angle, so as to facilitate the insertion end to be placed between the paper gaps for pressing the paper pile.

[0042] In another embodiment of the present invention, Figure 1 and Figure 7 As shown, the insertion end is provided with a blowing groove, and the bottom of the blowing groove is provided with a plurality of blowing holes for blowing out compressed gas, and the blowing holes are arranged in the middle position of the bottom of the blowing groove, and the gas blown out of the blowing holes is used to completely separate the paper sheets sucked up by the suction cup assembly 30 from the paper pile, so as to facilitate the transportation of the paper sheets.

[0043] In another embodiment of the present invention, Figures 1 to 6 and Fig. 9 As shown, the first rotating shaft and the second rotating shaft are located on the same vertical line, and the first rotating shaft is located above the second rotating shaft. The first rotating shaft and the second rotating shaft are arranged on the same vertical line, and the first rotating shaft is arranged above the second rotating shaft, so that the path of the first rotating connecting member 51 and the second rotating connecting member 52 driving the swing arm 54 to move is maximized.

[0044] In another embodiment of the present invention, Figure 1As shown, one end of the second rotating shaft rotatably connected to the mounting plate 12 extends outward through the mounting plate 12 and is connected to an adapter, and one end of the second rotating shaft passes through the mounting plate 12 and is fixedly connected to one end of the adapter, and the other end of the adapter is rotatably connected to the output end of the first driving gas rod 53, through one end of the adapter and one end of the second rotating shaft fixedly connected, and the other end is rotatably connected to the output end of the first driving gas rod 53, so that the adapter rotates around the second rotating shaft under the push of the output end of the first driving gas rod 53, thereby driving the second rotating shaft to rotate, so that the second rotating connection 52 follows the rotation of the second rotating shaft, and the rotation of the second rotating connection 52 drives the swing arm 54 to move, the swing arm 54 drives the pressure rod 55 to move, and the pressure rod 55 drives the paper pressing head 551 to move, so that the paper pressing head 551 follows the translation and curve movement.

[0045] In another embodiment of the present invention, Figures 1 to 6 and Fig. 9 As shown, a semi-arc connection portion 541 is provided at one end of the swing arm 54 connected to the first rotating connection member 51, and the arc-shaped opening of the semi-arc connection portion 541 faces the first rotating connection member 51 and the second rotating connection member 52, and the free end of the semi-arc connection portion 541 is rotationally connected to the connection portion of the first rotating connection member 51, and the connection portion of the second rotating connection member 52 is rotationally connected to the arc segment of the semi-arc connection portion 541. The setting of the semi-arc connection portion 541 maximizes the path of the swing arm 54 during movement, and there will be no collision with the first rotating shaft or the second rotating shaft in the middle to limit the displacement, thereby driving the pressure rod 55 and the paper pressing head 551 on the pressure rod 55 to move to the greatest extent, which is convenient for pressing the paper.

[0046] In another embodiment of the present invention, Figures 1 to 6 and Fig. 9 As shown, the other end of the swing arm 54 is provided with a vertical connecting portion 542, one end of the vertical connecting portion 542 is fixedly connected to one end of the semi-arc connecting portion 541, and the other end of the vertical connecting portion 542 is adjustably connected to the pressure rod 55. By providing the vertical connecting portion 542, sufficient installation space is provided for the adjustable connection of the pressure rod 55, so that the pressure rod 55 can be adjusted to adapt to different products.

[0047] In another embodiment of the present invention, Figures 1 to 6 and Fig. 9 As shown, the ratio between the first rotating connector 51 and the second rotating connector 52 is (9-11): (22-24), and the ratio can be 9:22, 10:23, 11:24, etc. By fixing the ratio between the first rotating connector 51 and the second rotating connector 52, the moving paths of the swing arm 54 and the pressure rod 55 are optimized.

[0048] In another embodiment of the present invention, Figures 1 to 6 and Fig. 9 As shown, the free end of the pressure rod 55 is bent toward the arc-shaped opening direction of the semi-arc-shaped connecting portion 541. Bending the pressure rod 55 toward the arc-shaped opening direction of the semi-arc-shaped connecting portion 541 can enable the paper pressing head 551 installed at one end of the pressure rod 55 to be better inserted into the paper gap to position and press the paper.

[0049] Another embodiment of the present invention provides a feeder head, such as Figures 7 to 9 As shown, it includes an installation shell 10, a transverse movable slide rail 20, a suction cup assembly 30, a second driving gas rod 40 and the above-mentioned feeder head pressing structure 50, the installation plate 12 is installed on the installation shell 10, the first rotating connection member 51, the second rotating connection member 52, the swing arm 54 and the pressure rod 55 are all located between the installation plate 12 and the installation shell 10, one end of the transverse movable slide rail 20 is fixedly installed between the installation plate 12 and the installation shell 10, and the other end of the transverse movable slide rail 20 extends outward, the suction cup assembly 30 is slidably installed below the transverse movable slide rail 20, and the suction cup assembly 30 is arranged adjacent to the installation shell 10, the second driving gas rod 40 is installed on the installation plate 12, and the second driving gas rod 40 is located above the first driving gas rod 53, and the output end of the second driving gas rod 40 is connected to the suction cup assembly 30.

[0050] The fly head in the present invention includes a mounting shell 10, a transverse moving slide rail 20, a suction cup assembly 30, a second driving air rod 40 and the above-mentioned fly head pressing structure 50. One end of the transverse moving slide rail 20 is fixedly mounted on the inner walls on both sides of the mounting shell 10. By directly fixing the transverse moving slide rail 20 on the inner walls on both sides of the mounting shell 10, the installation of the transverse moving slide rail 20 is more convenient. Then, the suction cup assembly 30 is slidably mounted below the part of the transverse moving slide rail 20 outside the mounting shell 10, so that the suction cup assembly 30 and the mounting shell 10 are adjacently arranged for moving paper. The second driving air rod 40 and the first driving air rod 53 are installed on the side of the installation shell 10 to save space. At the same time, the second driving air rod 40 is placed horizontally. Through the connection between the output end of the second driving air rod 40 and the suction cup assembly 30, the suction cup assembly 30 is driven to move repeatedly under the movement of the output end of the second driving air rod 40. The first rotating connecting member 51 and the second rotating connecting member 52 of the feeder head pressing structure 50 both use the two ends of the rotating shaft to pass through the inner walls of the installation shell 10 that are relatively arranged to realize the rotational installation of the first rotating connecting member 51 and the second rotating connecting member 52.

[0051] The first rotating connection member 51 and the second rotating connection member 52 are respectively connected to the free end and the middle part of the semi-arc connecting part 541 on the swing arm 54 to realize the limitation of the running trajectory of the connecting rod. One end of the rotating shaft of the second rotating connection member passes through the inner wall of the mounting shell 10 and is connected to the output end of the first driving gas rod 53 through the adapter. The output end of the first driving gas rod 53 drives the adapter to make a curved motion around the second rotating connection member 52, driving the second rotating connection member 52 to rotate. At the same time, the connecting part of the first rotating connection member 51 is shorter than the connecting part of the second connecting member. After 52 rotates, the connecting rod is pushed upward to make the connecting rod move diagonally upward by an end distance. Then, due to the rotational connection with the first rotating connecting member 51, the connecting portion of the first rotating connecting member 51 is pushed to start a circular motion around the rotation axis of the first rotating connecting member 51, driving the end of the connecting rod to move. The connecting portion of the second rotating connecting member 52 rotates around the rotation axis of the second rotating connecting member 52, driving the connecting rod to continue to move diagonally upward. At the same time, under the traction of the connecting portion of the first rotating connecting member 51, the pressure rod 55 at the other end starts to move in a curve, thereby realizing that the movement trajectory of the pressure rod 55 is divided into diagonal upward translation movement and curve movement. Through the above-mentioned arrangement, when the suction cup assembly 30 sucks the paper and moves upward, the pressure rod 55 first moves to the top of the paper edge through a curve, and then presses the paper by moving downward, so as to avoid directly inserting into the gap between the papers and pressing the paper to push out the top layer of paper, and to avoid colliding with the suction cup assembly 30, which affects the subsequent workstations and leads to the problem of low production efficiency. In another embodiment of the present invention, Figures 1 to 3 As shown, the mounting shell 10 is equipped with a blowing assembly 11, and the blowing assembly 11 is located directly above the paper pressing head 551. The hole on the blowing assembly 11 is set at the lower end of the blowing assembly 11. By cooperating with the blowing hole set on the paper pressing head 551, the sucked paper sheets are completely separated from the paper pile below, which is convenient for the subsequent transportation of paper sheets.

[0052] like Figures 7 to 9 As shown, the blowing assembly 11 includes a fixed plate and a plurality of blowing rods, the fixed plate is installed on the side of the mounting shell 10, and the fixed plate and the blowing rods are all located above the paper pressing head 551, the blowing rods are fixedly installed on the fixed plate, and the blowing rods are respectively located above both sides of the paper pressing head 551, and the blowing rods are arranged on both sides of the paper pressing head 551 by fixing them on the fixed plate, and the position between the sucked paper and the paper pile is blown in cooperation with the blowing holes set on the paper pressing head 551, and the positions on both sides of the paper sheet are separated by the setting of the blowing rods, which makes the movement of the paper sheet more convenient.

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
