Description

Technical Field

[0001] This invention relates to the field of printing and binding machinery technology, and more particularly to a power drive system for feeding and pasting collators. Background Technology

[0002] A collating machine is a device that combines sheets of paper of different numbers together. By replacing manual labor in this collating task, the machine can reduce the workload of operators, improve work efficiency, and can be used independently or in conjunction with offset printing equipment to improve collating quality and speed, thus ensuring work efficiency.

[0003] Therefore, clamp-type collating machines and roller-type collating machines have emerged on the market. Clamp-type collating machines use reciprocating clamps for collating, with each reciprocating motion of the clamp picking up one page. The opening and closing of the clamp is controlled by a cam mechanism. The clamp-type collating machine has a complex mechanism and is noisy during operation, with its mechanism and process being relatively complicated. Roller-type collating machines use a rotating gripper wheel that engages with gripper teeth to pick up pages. The gripper wheel drives the gripper teeth to rotate, and each rotation of the gripper wheel completes the collating process for one page. Both of these existing collating machines on the market use a power mechanism to drive the gripper cam and other mechanisms to work. They cannot be stopped and separated during operation, which affects their production efficiency. Summary of the Invention

[0004] To address the problems of existing technologies, this invention provides a power drive system for feeding labels in a collating machine. The cam mechanism is controlled by a separate pneumatic connection mechanism, which connects the power output mechanism to the cam assembly. The pneumatic connection mechanism can control the power output mechanism independently, ensuring that the power input and power output mechanisms of the cam assembly do not interfere with each other. This facilitates adjustments to the label feeding operation of the collating machine by the operator. Furthermore, the working mechanism has a simple structure and is easy to adjust.

[0005] The solution adopted by the present invention to solve its technical problem is: a power drive system for feeding labels in a collating machine, including a frame and a power input mechanism and a power output mechanism mounted on the frame. The power input mechanism includes a cam assembly and a pull rod rotatably connected to the cam assembly at one end. The power output mechanism includes a rotating shaft for transmitting power, a swing seat rotatably sleeved on the rotating shaft, and a connecting block connected to the rotating shaft. The other end of the pull rod connected to the cam assembly is rotatably connected to the swing seat and drives the swing seat to swing. A pneumatic connection mechanism for connecting the swing seat and the connecting block is also installed on the connecting block.

[0006] Furthermore, the cam assembly includes a drive motor, a cam, and a swing arm. The cam is fixedly connected to the output shaft of the drive motor, the swing arm is rotatably mounted on the frame, the cam is connected to the swing arm and drives the swing arm to swing, and one end of the pull rod is rotatably connected to the swing arm.

[0007] Furthermore, the end face of the swing arm is provided with rollers, and the edge of the cam is in contact with the rollers.

[0008] Furthermore, the connecting block includes a connecting part and a plug-in part. The connecting part is coaxially connected to the rotating shaft, the plug-in part is located on one side of the connecting part, and a mounting plate is provided on the connecting part. The pneumatic connecting mechanism is fixedly installed on the mounting plate and connected to the plug-in part.

[0009] Furthermore, the pneumatic connection mechanism includes a cylinder fixedly mounted on the mounting plate and a connecting rod fixedly connected to the cylinder piston rod. The insertion part is provided with an insertion hole, and the connecting rod is movably inserted into the insertion hole.

[0010] Furthermore, the swing seat is provided with a bearing, the rotating shaft is inserted into the bearing, the swing seat is provided with a connecting shaft and a connecting hole on both sides, the end of the pull rod connected to the swing seat is rotatably connected to the connecting shaft, the connecting hole and the insertion hole are in corresponding positions, and the cylinder drives the connecting rod to pass through the insertion hole and insert into the connecting hole.

[0011] Furthermore, a limiting plate is installed on the frame, and a limiting hole is provided on the end face of the limiting plate, through which the connecting rod passes.

[0012] In summary, the beneficial effects of the present invention are as follows: The present invention rotates the swing seat onto the rotating shaft and connects the swing seat and the cam assembly through a pull rod. At the same time, a pneumatic connection mechanism is set to connect the swing seat and the rotating shaft. When the cam assembly rotates and pulls the pull rod, the swing seat will drive the rotating shaft to rotate under the action of the pneumatic connection mechanism, thereby realizing the output of power. Furthermore, after the pneumatic connection mechanism is disengaged, the power output mechanism can be stopped without stopping the power input mechanism. This allows the operator to adjust the labeling operation of the collating machine without stopping the machine, making the adjustment method convenient.

[0020] To make the content of this invention easier to understand, the invention will be further described below with reference to specific embodiments and accompanying drawings.

[0021] It should be noted that the terms "center," "upper," "lower," "front," "rear," "left," "right," "top," "inner," and "outer," etc., used herein to indicate the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are used only for the convenience of describing the invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Unless otherwise stated, "a plurality of" means two or more.

[0022] Unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art will understand the specific meaning of these terms in this invention based on the specific circumstances.

[0023] like Figure 1 and Figure 3As shown, a power drive system for feeding labels in a collating machine includes a frame (not shown) and a power input mechanism 1 and a power output mechanism 2 mounted on the frame. The power output mechanism 2 is connected to the label feeding conveyor mechanism, and power is transmitted from the power input mechanism 1 to the power output mechanism 2 to realize the label feeding operation of the collating machine. In this embodiment, the power input mechanism 1 includes a cam assembly 11 and a pull rod 12 rotatably connected to the cam assembly 11 at one end. The power output mechanism 2 includes a rotating shaft 21 connected to the label feeding conveyor mechanism, a swing seat 22 rotatably sleeved on the rotating shaft 21, and a connecting block 23 connected to the rotating shaft 21. In this embodiment, the other end of the pull rod 12 connected to the cam assembly 11 is rotatably connected to the swing seat 22, so that when the cam assembly 111 is working, it can drive the pull rod 12 to swing, and the other end of the pull rod 12 drives the swing seat 22 to swing on the rotating shaft 21. At this time, the power input mechanism 1 is working, but the power output mechanism is not. The absence of any movement ensures that the power input mechanism 1 and power output mechanism 2 operate independently, facilitating adjustments to the collating machine's feeding operation by the operator. To enable the power provided by the cam assembly 11 to drive the power output mechanism 2 and thus achieve the collating machine's feeding operation, a pneumatic connection mechanism 3 is also installed on the connecting block 23. This embodiment connects the connecting block 23, which is connected to the rotating shaft 21, to the swing seat 22 via the pneumatic connection mechanism 3. When the swing seat 22 swings under the pull of the pull rod 12, it can drive the connecting block 23 to swing under the action of the pneumatic connection mechanism 3, thereby driving the rotating shaft 21 to rotate reciprocally, achieving the reciprocating feeding of the collating machine. When adjustments to the feeding process are needed, the pneumatic connection mechanism 3 disengages, disconnecting the connection between the connecting block 23 and the swing seat 22. This allows the power output mechanism 2 to stop working without stopping the power input, facilitating adjustments by the operator. The structure is simple and easy to adjust.

[0024] like Figure 1 and Figure 2 As shown, the cam assembly 11 of this embodiment includes a drive motor, a cam 111, and a swing arm 112. The cam 111 is fixedly connected to the output shaft of the drive motor, so that the drive motor can drive the cam 111 to rotate when it is working. The swing arm 112 of this embodiment is rotatably mounted on the frame, and the cam 111 is connected to the swing arm 112. When the cam 111 rotates under the action of the drive motor, the protrusion on the cam 111 can push the swing arm 112 to swing down, thereby realizing the swing of the swing arm 112. One end of the pull rod 12 of this embodiment is rotatably connected to the swing arm 112. When the swing arm 112 swings, it can drive the pull rod 12 to swing up and down, thereby driving the swing seat 22 connected to the pull rod 12 to swing back and forth on the rotating shaft 21.

[0025] To improve the swing stability of the swing arm 112, a roller 113 is provided on the front end face of the swing arm 112 in this embodiment, and the edge of the cam 111 is in contact with the roller 113, so that when the cam 111 rotates, the roller 113 can roll on the edge of the goose-formation cam 111, thereby improving the swing accuracy of the swing arm 112 and achieving precise feeding.

[0026] like Figure 3 As shown, the connecting block 23 in this embodiment includes a connecting part 231 and an insert part 232. The connecting part 231 is coaxially connected to the rotating shaft 21, so that when the connecting block 23 rotates, it can drive the rotating shaft 21 to rotate around its own axis, thereby improving the feeding accuracy of the collating machine. The insert part 232 in this embodiment is connected to one side of the connecting part 231 and is integrally formed with the connecting part 231. The connecting part 231 in this embodiment is provided with a mounting plate 233, and the pneumatic connecting mechanism 3 is fixedly installed on the mounting plate 233. After the pneumatic connecting mechanism 3 connects the connecting block 23 and the swing seat 22, the pneumatic connecting mechanism 3 can swing together with the connecting block 23.

[0027] like Figure 3 As shown, the pneumatic connection mechanism 3 of this embodiment includes a cylinder 31 fixedly mounted on the mounting plate 233 and a connecting rod 32 fixedly connected to the piston rod of the cylinder 31, so that the cylinder 31 can control the extension and retraction of the connecting rod 32 to realize the connection between the connecting block 23 and the swing seat 22; the insertion part 232 is provided with an insertion hole, and the connecting rod 32 of this embodiment is movably inserted into the insertion hole, so that after the connecting block 23 and the swing seat 22 are connected through the connecting rod 32, the swing of the connecting rod 32 can drive the insertion part 232 to swing, thereby realizing the swing of the connecting block 23, and finally realizing the reciprocating rotation of the rotating shaft 21; the connecting rod 32 of this embodiment is movably connected to the insertion hole, which facilitates the movement of the connecting rod 32 in the insertion hole to realize the connection or disconnection between the connecting block 23 and the swing seat 22.

[0028] like Figure 5 As shown, in order to allow the swing seat 22 to swing on the rotating shaft 21, a bearing is provided inside the swing seat 22 in this embodiment, and the rotating shaft 21 is inserted into the bearing. This allows the swing seat 22 to rotate smoothly on the rotating shaft 21 under the action of the bearing when the connecting block 23 is not connected to the swing seat 22. In this embodiment, the swing seat 22 has a connecting shaft 221 and a connecting hole 222 on both sides. One end of the pull rod 12 connected to the swing seat 22 is rotatably connected to the connecting shaft 221. The connecting hole 222 corresponds to the insertion hole. The cylinder 31 drives the connecting rod 32 through the insertion hole and inserts it into the connecting hole 222. Therefore, when the cam assembly 11 controls the pull rod 12 to swing up and down, it can pull the swing seat 22 to rotate on the rotating shaft 21, thereby causing the connecting rod 32 inserted into the connecting hole 222 to swing. This causes the connecting block 23 to swing back and forth under the drive of the connecting rod 32, thus realizing the reciprocating rotation of the rotating shaft 21, thereby outputting power to the collating machine's feeding mechanism for feeding. Figure 4 As shown, when the cylinder 31 controls the connecting rod 32 to exit from the connecting hole 222, the connecting rod 32 disengages from the swing seat 22 and stops rotating, thereby stopping the connecting block 23 from swinging, thus stopping the rotating shaft 21 from working. At this time, the cam assembly 11 still controls the pull rod 12 to drive the swing seat 22 to rotate on the rotating shaft 21, realizing the function that the power input and power output mechanisms 2 can work without interference in this embodiment, which is convenient for the staff to make adjustments.

[0029] like Figures 1 to 3 As shown, a limiting plate 4 is also installed on the frame of this embodiment, and a limiting hole 41 is provided on the end face of the limiting plate 4. The connecting rod 32 is inserted into the limiting hole 41, so that when the connecting rod 32 swings under the drive of the swing seat 22, the swing angle of the connecting rod 32 can be limited by the limiting hole 41, thereby limiting the range of reciprocating rotation of the rotating shaft 21, which facilitates the accurate feeding of pages in the collating machine's pasting process.

[0030] The working principle of this embodiment is as follows: In this embodiment, the swing seat 22 is rotatably sleeved on the rotating shaft 21, and the swing seat 22 is connected to the cam assembly 11 by the pull rod 12. At the same time, a pneumatic connection mechanism 3 is set to connect the swing seat 22 and the rotating shaft 21. When the cam assembly 11 rotates and pulls the pull rod 12, the swing seat 22 will drive the rotating shaft 21 to rotate under the action of the pneumatic connection mechanism 3, thereby realizing the output of power. After the pneumatic connection mechanism 3 is disengaged, the power output mechanism 2 can be stopped without stopping the power input mechanism 1. This allows the operator to adjust the labeling operation of the collating machine without stopping the machine, and the adjustment method is convenient.

[0031] The embodiments described above are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and modifications made by those skilled in the art based on the invention shall fall within the scope of protection of the present invention.
