Description

Technical Field

[0001] This utility model relates to the field of paper folding machine technology, and in particular to a rapid paper feeding device for a paper folding machine. Background Technology

[0002] Folding machines, widely used in printing, packaging, and office supplies, primarily fold single sheets of paper along pre-set crease lines to meet the processing needs of various products. With the continuous improvement of modern industrial automation and stringent requirements for production efficiency, the operating speed and stability of folding machines have become key indicators for evaluating their performance. Among these, the paper feeding stage, as the initial step in the folding process, directly impacts the overall production speed and finished product quality.

[0003] Currently, the paper feeding mechanism of most common folding machines on the market mainly consists of a conveyor belt and paper feeding rollers. The paper is separated and transported by the cooperation of the conveyor belt and friction rollers, and finally carried into the folding unit of the folding machine by the paper gripper bar or similar mechanism for folding.

[0004] However, in actual use, due to the large differences in rigidity, surface smoothness and weight of different types of paper (such as coated paper, offset paper, and specialty paper), traditional paper feeding devices often have difficulty in stably and reliably transmitting various types of paper. This can easily lead to double-sheet feeding (multiple sheets of paper are fed in at the same time) or blank sheets (papers are not effectively separated), affecting the continuity and stability of paper feeding. Furthermore, traditional paper feeding mechanisms are not convenient for positioning and guiding paper of different sizes, which reduces the overall applicability of the mechanism.

[0005] Therefore, existing technologies have shortcomings and need to be improved. Utility Model Content

[0006] The purpose of this invention is to solve the problems that existing paper feeding mechanisms are difficult to adapt to different types of paper, are prone to double-sheet feeding or blank sheets, and are inconvenient to position and guide paper of different sizes. Therefore, a fast paper feeding device for a paper folding machine is proposed.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A rapid paper feeding device for a paper folding machine includes a belt conveyor with a frame fixedly mounted on top, paper feeding rollers mounted on the frame, and further includes: at least two baffles disposed on the frame, wherein the belt conveyor is provided with a first adjusting member for driving the two baffles to move closer to each other and further apart; at least two guide plates disposed in the middle of the frame, wherein the bottom ends of the guide plates are arc-shaped for smoothly conveying paper, and the frame is provided with a second adjusting member for driving the guide plates to rise and fall; and a pad disposed on the belt conveyor, wherein the pad has an inclined surface for supporting paper, and the belt conveyor is provided with a third adjusting member for driving the pad to move along the paper feeding direction of the belt conveyor.

[0009] To facilitate adjustment of the distance between the two baffles, preferably, the first adjusting component includes a movable frame and a second adjusting bolt.

The baffle has a screw hole, and a positioning piece is fixedly connected to the second adjusting bolt. The second adjusting bolt passes through an opening on the frame and is threaded into the screw hole to make the positioning piece press against the surface of the frame.

[0010] To facilitate adjustment of the guide plate height, preferably, the second adjusting component includes a folded plate fixedly connected to the frame, a third adjusting bolt rotatably connected to the folded plate, a lifting plate slidably connected longitudinally to the folded plate, the lifting plate being threadedly connected to the third adjusting bolt, and the guide plate being fixedly connected to the lifting plate.

It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component centrally located at the same time.

[0029] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] Reference Figures 1-6This utility model embodiment provides a rapid paper feeding device for a paper folding machine, including a belt conveyor 1 with a frame 2 fixedly mounted on top. The frame 2 has an opening, and paper feeding rollers 3 are installed on the frame 2. Through the cooperation of the paper feeding rollers 3 and the belt conveyor 1, paper can be conveyed. Here, the belt conveyor 1 is a mature existing technology and will not be described in detail. It also includes at least two baffles 4, which are disposed on the frame 2. The belt conveyor 1 is provided with a first adjusting member, which is used to drive the two baffles 4 to interact. Approaching and moving away; at least two guide plates 5 are set in the middle of the frame 2, and the bottom end of the guide plate 5 is arc-shaped to smoothly conduct paper. The frame 2 is provided with a second adjusting member for driving the guide plate 5 to rise and fall; a pad 6 is set on the belt conveyor 1, wherein the pad 6 is provided with an inclined surface for supporting the paper, and the angle between the inclined surface of the pad 6 and the bottom surface is 20°-60°. This device takes 40° as a preferred example. The belt conveyor 1 is provided with a third adjusting member for driving the pad 6 to move along the paper feeding direction of the belt conveyor 1.

[0031] Specifically, during use, the support position of the pad 6 can be flexibly adjusted by the setting of the third adjusting component, and the friction between the paper and the conveyor belt of the belt conveyor 1 can be changed. In this way, the appropriate friction required by different types of paper can be flexibly set, so that the device can stably and reliably transmit various types of paper, greatly reducing the probability of double-sheet feeding or blank sheets, and helping to improve the continuity and stability of paper feeding. Furthermore, the setting of the first and second adjusting components makes it easy to flexibly adjust the distance between the two baffles 4, so that the device can position and guide paper of different sizes. It also makes it easy to adjust the height of the guide plate 5, so that the device can position and guide paper of different thicknesses, so that each sheet of paper can be smoothly conveyed. Through the above adjustments, the applicability of the device can be greatly improved.

[0032] The first adjusting component includes a movable frame 41 and a second adjusting bolt 42. The movable frame 41 is slidably connected to the frame 2, and the baffle 4 is fixedly connected to the movable frame 41. The baffle 4 has a screw hole, and the second adjusting bolt 42 has a positioning piece 43 fixedly connected to it. The second adjusting bolt 42 passes through the opening on the frame 2 and is threaded into the screw hole to make the positioning piece 43 press against the surface of the frame 2.

[0033] Specifically, in use, by rotating the second adjusting bolt 42, the positioning piece 43 is moved away from the frame 2 under the action of the thread, thereby releasing the fixation of the baffle 4. Then, the baffle 4 is slid laterally on the frame 2 by the moving frame 41. After the two baffles 4 are adjusted to be evenly spaced, the second adjusting bolt 42 can be rotated in the opposite direction to make the positioning piece 43 press against the surface of the frame 2, thereby fixing the baffle 4. The positioning piece 43, the second adjusting bolt 42 and the moving frame 41 make it easy to adjust the distance between the two baffles 4, so that the device can position and guide paper of different sizes, thereby improving the applicability of the device.

[0034] The second adjusting component includes a folding plate 51 fixedly connected to the frame 2, a third adjusting bolt 52 rotatably connected to the folding plate 51, a lifting plate 53 longitudinally slidably connected to the folding plate 51, the lifting plate 53 being threadedly connected to the third adjusting bolt 52, and a guide plate 5 fixedly connected to the lifting plate 53.

[0035] Specifically, by rotating the third adjusting bolt 52, the lifting plate 53 can be driven to move up and down along the folded plate 51, and the guide plate 5 can be driven to move up and down synchronously. This makes it easy to adjust the height of the guide plate 5, so that the device can position and guide paper of different thicknesses, and each sheet of paper can be smoothly conveyed, further improving the applicability of the device.

[0036] The third adjusting component includes a slider 62 fixedly connected to the bottom surface of the pad 6. A groove 61 is provided on the belt conveyor 1. The slider 62 is slidably connected in the groove 61. A fourth adjusting bolt 63 is rotatably connected in the groove 61. The slider 62 is threadedly connected to the fourth adjusting bolt 63. One end of the fourth adjusting bolt 63 extends to the outside of the belt conveyor 1 and is fixedly connected to a handwheel 64.

[0037] Specifically, during use, by rotating the handwheel 64 and driving the fourth adjusting bolt 63 to rotate, the fourth adjusting bolt 63 slides laterally along the slide groove 61 under the action of the thread, and drives the pad 6 to move closer to or further away from the guide plate 5. This allows for easy adjustment of the support position of the guide plate 5 on the paper. The closer the pad 6 is to the guide plate 5, the larger the paper tilt angle, and the smaller the contact area between the paper and the conveyor belt 1, resulting in lower friction. Conversely, the farther the pad 6 is from the guide plate 5, the smaller the paper tilt angle, and the larger the contact area between the paper and the conveyor belt 1, resulting in higher friction. By changing the support position of the pad 6 and altering the friction between the paper and the conveyor belt 1, the appropriate friction required for different types of paper can be flexibly set. This enables the device to stably and reliably transmit various types of paper, greatly reducing the probability of double-sheet feeding or blank sheets, and helping to improve the continuity and stability of paper feeding.

[0038] A support plate 31 is fixedly connected to the bottom of the frame 2. A first adjusting bolt 33 is threadedly connected to the support plate 31. A limit rod 32 is longitudinally slidably connected to the support plate 31. The paper feeding roller 3 is fixedly connected to the bottom end of the limit rod 32. The paper feeding roller 3 is rotatably connected to the bottom end of the first adjusting bolt 33.

[0039] Specifically, by rotating the first adjusting bolt 33, the paper feeding roller 3 can be driven to move up and down, which makes it easy to adjust the distance between the paper feeding roller 3 and the conveyor belt of the belt conveyor 1, so as to convey paper of different thicknesses and improve the applicability of the device.

[0040] Working principle: During use, the fast paper feeding device of this paper folding machine first adapts and adjusts the device according to the paper type, size and thickness. By rotating the second adjusting bolt 42, the positioning piece 43 is moved away from the frame 2 under the action of the thread, so as to release the fixation of the baffle 4. Then, the baffle 4 is slid laterally on the frame 2 by the moving frame 41. After the two baffles 4 are adjusted to be evenly spaced, the second adjusting bolt 42 can be rotated in the opposite direction to make the positioning piece 43 press against the surface of the frame 2, thereby fixing the baffle 4. The positioning piece 43, the second adjusting bolt 42 and the moving frame 41 make it easy to adjust the distance between the two baffles 4, so that the device can position and guide paper of different sizes.

[0041] Furthermore, by rotating the third adjusting bolt 52, the lifting plate 53 can be driven to move up and down along the folded plate 51, and the guide plate 5 can be moved up and down synchronously. This makes it easy to adjust the height of the guide plate 5, so that the device can position and guide paper of different thicknesses, and each sheet of paper can be smoothly conveyed.

[0042] Then, by rotating the handwheel 64 and driving the fourth adjusting bolt 63 to rotate, the fourth adjusting bolt 63 slides laterally along the slide groove 61 under the action of the thread, and drives the pad 6 to move closer to or further away from the guide plate 5. This makes it easy to adjust the support position of the guide plate 5 on the paper. The closer the pad 6 is to the guide plate 5, the larger the paper tilt angle and the smaller the contact area between the paper and the conveyor belt of the belt conveyor 1, and the smaller the friction. Conversely, the farther the pad 6 is from the guide plate 5, the smaller the paper tilt angle and the larger the contact area between the paper and the conveyor belt of the belt conveyor 1, and the greater the friction. By changing the support position of the pad 6, the friction between the paper and the conveyor belt of the belt conveyor 1 can be changed. This allows for flexible setting of the appropriate friction required for different types of paper, enabling the device to stably and reliably transmit various types of paper, greatly reducing the probability of double-sheet feeding or blank sheets, and helping to improve the continuity and stability of paper feeding.

[0043] On the other hand, when in use, the user places the paper stacked on the inclined surface of the pad 6. At this time, the paper is located between the two baffles 4 and abuts against the guide plate 5. By starting the belt conveyor 1, the paper below is quickly fed out by the belt conveyor 1 and the paper feeding roller 3 in sequence, and is brought into the folding unit for folding by the paper gripper bar or similar mechanism on the folding machine.

[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
