Description

Technical Field

[0001] The present invention belongs to the technical field related to paper stacking supports, and more specifically, particularly relates to a paper stacking support assembly for a printing press with an adjustment function. Background Art

[0002] The paper stacking support assembly for a printer, also often called a print output support or a print paper receiving tray, is an accessory designed specifically for a printer. Its main purpose is to better manage and collect printed paper, ensure that the print job can be output neatly and orderly, and avoid paper scattering or confusion. However, the paper stacking support in the prior art has the following defects: 1. In the prior art, the paper stacking bracket uses a simple bracket to place the paper pile, but the simple bracket does not have a clamping effect and causes the paper to flutter. The fluttering paper increases the workload of sorting and correctly stacking, prolongs the time for preparing printing materials, and reduces the overall work efficiency; 2. In the prior art, when stacking paper in piles, workers use simple hard boards to place on the surface of the paper pile for protection. However, improper edge treatment of some hard boards or during transportation may cause scratches to the paper or operators. 3. In the prior art, if the paper stacking support is simply pressed by the upper surface, the pressure may be concentrated on the top edge of the paper stack, resulting in local deformation or damage. In addition, there is no side support, and the overall stability of the paper stack is poor. Even a slight vibration may cause the paper to be misplaced or scattered, which is not conducive to the orderly management of documents.

[0006] According to a further technical solution, a winding rope is provided at one end of the limit rod, and the other end of the limit rod passes through the rear box and is connected to the connecting rod and is provided with a first transmission belt.

[0007] According to a further technical solution, two vertical poles are symmetrically arranged on the surface of the rear box, a guard plate is connected between the two vertical poles, and a pulley is installed on the surface of the guard plate.

[0008] According to a further technical solution, a pull rope is slidably provided on the surface of the pulley, one end of the pull rope is connected to the winding rope, and the other end of the pull rope is connected to the contact plate.

[0009] According to a further technical solution, the fixing device comprises a protective top plate, a plurality of annular mounting frames are arranged in an array on the surface of the protective top plate, a plurality of folding plates are arranged on the surfaces of the plurality of annular mounting frames, a rotating shaft is connected between the plurality of annular mounting frames and the plurality of folding plates, and an outer end rod is connected to one end of the rotating shaft.

[0010] A further technical solution is that the protective top plate surface array is provided with four sliding bars, the four sliding bars are arranged on the outside of the annular mounting frame, a movable plate is slidably provided between the four sliding bars, the upper surface of the movable plate is connected to one end of the folding plate provided in the array, and the lower surface of the movable plate is provided with a plurality of extrusion springs in the array, and a flexible plate is connected to the surface of the plurality of extrusion springs.

[0011] According to a further technical solution, a second transmission belt is provided to connect the first transmission belt and the connecting rod.

[0012] According to a further technical solution, slide grooves are symmetrically arranged on both sides of the lower shell, and the slide grooves are in contact with the sliding plate.

[0013] According to a further technical solution, a tray is provided above the thickened protective cover, the tray comprises a tray plate, and a plurality of pads are arranged in an array on the bottom surface of the tray plate.

[0014] According to a further technical solution, a plurality of notches are provided on the surface of the thickened protective cover, the plurality of notches are in contact with a plurality of the pads, and the bottom surface of the pads is in contact with the surface of the contact plate.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The present invention provides a paper stacking support assembly for a printing press with an adjustment function. When a tray is placed on a surface, a pad at the bottom of the tray will contact the surface of a contact plate, causing the contact plate to be under pressure and begin to sink under pressure. This squeezing action in turn pulls the pull rope, because the contact plate will exert a pulling force on the pull rope when it descends. After the pull rope senses the pulling force, it will cause the winding rope to rotate in the opposite direction. The reverse action of the winding rope drives the limit rod to rotate, and the limit spring installed on the surface of the limit rod plays a role in limiting and fixing the position of the limit rod. Subsequently, the rotation of the limit rod further triggers the rotation of the connecting rod. As the connecting rod rotates, it drives the slider to move in the same direction. The movement of the slider directly causes the sliding plate to translate inward. In this process, the inward tightening action of the sliding plate causes the side baffles symmetrically arranged on both sides to move inward synchronously, thereby achieving a stable clamping of both sides of the paper pile. Moreover, by clamping on both sides, the paper pile can be effectively prevented from tilting or collapsing during processing, transportation or storage, thereby improving the stability of the overall operation. The precise and uniform clamping force can reduce the friction and collision between cardboards, and reduce the risk of damage to the edge or surface of the cardboard during operation, which is especially important for materials that are fragile or need to maintain flatness.

[0016] The present invention discloses a paper stacking support assembly for a printing press with an adjustment function. When the connecting rod rotates, the second transmission belt arranged on the surface drives the outer end rod to rotate. Then, the rotation of the outer end rod causes the rotating shaft to start rotating, thereby guiding the folding plate to fold and stretch. In this process, the movement of the folding plate drives the movable plate to slide along the surface of the sliding rod. It is particularly noteworthy that once the outer end rod receives the rotation force, it will cause the movable plate to press downward. At this time, the flexible plate installed on the surface of the extrusion spring presses the topmost paper to prevent the paper from being damaged by wind or dust during placement or operation, thereby ensuring that the paper is intact. In addition, the specially designed pressing mechanism uses the flexible plate to press the paper, effectively preventing external factors such as wind or dust from causing pollution and damage to the paper, which is particularly important for keeping the paper clean and avoiding damage, especially when used outdoors or in dusty environments. Moreover, such a mechanical structure can be adjusted according to different needs, such as by changing the transmission ratio, the material or pressure of the flexible plate, etc., to adapt to the processing of paper of different thicknesses or materials, thereby increasing the versatility and adaptability of the equipment.

[0017] The invention discloses a paper stacking support assembly for a printing press with an adjustment function, which realizes the automatic adjustment function of the paper stacking support through a complex mechanical structure composed of a connecting rod, a transmission belt, an outer end rod and a rotating shaft. The transmission ratio, the material of the flexible plate and the pressure can be adjusted according to the thickness and material of the paper, thereby improving the adaptability of the equipment to various operating conditions. The sliding plate, the side baffle plate and the clamping mechanism in the design work together to not only firmly clamp the two sides of the paper stack, effectively prevent the paper stack from tilting or collapsing, but also protect the paper from pollution and damage from the external environment such as wind or dust through the uniform pressure applied by the flexible plate. The paper stacking support assembly is particularly suitable for paper processing occasions with high requirements for flatness and cleanliness. The integrated mechanical linkage design simplifies the operation process, and the user only needs to perform simple manipulation to realize the rapid loading, fixing and protection of the paper stack, thereby improving the work efficiency and reducing the labor intensity of the operator. The paper stacking support assembly can reduce unnecessary friction and collision between the paper boards by accurately controlling the clamping force of the paper, thereby effectively reducing the risk of damage to the edge or surface of the paper board during the processing, thereby ensuring the quality of the final printed product.

[0035] Specific use of the present invention: When the present invention is used, it is first placed at a designated location in the workshop. Then, the operation process is as follows: stack the printing papers one by one on the pallet until the preset thickness is reached; at this time, the pallet filled with papers is carefully moved to the device of the present invention by a forklift. Before placing the pallet, it is necessary to ensure that the pad 18 at the bottom of the pallet can accurately fit into the notch on the thickened protective cover 17. After accurate docking, slowly put down the pallet.

[0036] Once the tray is securely placed, the built-in fixing device 12 and the paperboard stacking device 14 are activated and work together to firmly fix the paper pile. Specifically, the pad 18 at the bottom of the tray touches the contact plate 46, and the pressure generated thereby causes the contact plate 46 to sink; as the contact plate 46 descends, it pulls the connected pull rope 30, which further drives the winding rope 36 to rotate counterclockwise; the rotation of the winding rope 36 triggers the rotation of the limit rod 26, and the limit spring 35 limits the limit rod 26 during this process to ensure stable movement. The limit rod 27 rotates accordingly, and drives the sliding plate 32 to move inward through the slider 47 on it. At the same time, the side baffles 21 on both sides are synchronously retracted to jointly achieve a stable clamping of the paper pile.

[0037] In addition, the rotation of the connecting rod 27 also transmits power to the outer end rod 38 through the second transmission belt 29 thereon, causing the rotation of the rotating shaft 43, driving the folding plate 42 to perform telescopic folding movement, and then sliding along the slide rod 39 through the moving plate 40, applying gentle pressure to the top layer of paper, which is protected by the flexible plate 45 to prevent external factors such as dust from damaging the paper. If the paper pile needs to be moved, just trigger the release mechanism of the limit spring 35 to unlock it, and the forklift can be used again to safely lift and transfer the paper pile. The whole process is smooth and efficient, and the details are properly controlled.

[0038] The present invention provides a paper stacking support assembly for a printing press with an adjustment function. When a tray is placed on a surface, a pad at the bottom of the tray will contact the surface of a contact plate, causing the contact plate to be under pressure and begin to sink under pressure. This squeezing action in turn pulls the pull rope, because the contact plate will exert a pulling force on the pull rope when it descends. After the pull rope senses the pulling force, it will cause the winding rope to rotate in the opposite direction. The reverse action of the winding rope drives the limit rod to rotate, and the limit spring installed on the surface of the limit rod plays a role in limiting and fixing the position of the limit rod. Subsequently, the rotation of the limit rod further triggers the rotation of the connecting rod. As the connecting rod rotates, it drives the slider to move in the same direction. The movement of the slider directly causes the sliding plate to translate inward. In this process, the inward tightening action of the sliding plate causes the side baffles symmetrically arranged on both sides to move inward synchronously, thereby achieving a stable clamping of both sides of the paper pile. Moreover, by clamping on both sides, the paper pile can be effectively prevented from tilting or collapsing during processing, transportation or storage, thereby improving the stability of the overall operation. The precise and uniform clamping force can reduce the friction and collision between cardboards, and reduce the risk of damage to the edge or surface of the cardboard during operation, which is especially important for materials that are fragile or need to maintain flatness.

[0039] The present invention discloses a paper stacking support assembly for a printing press with an adjustment function. When the connecting rod rotates, the second transmission belt arranged on the surface drives the outer end rod to rotate. Then, the rotation of the outer end rod causes the rotating shaft to start rotating, thereby guiding the folding plate to fold and stretch. In this process, the movement of the folding plate drives the movable plate to slide along the surface of the sliding rod. It is particularly noteworthy that once the outer end rod receives the rotation force, it will cause the movable plate to press downward.

The transmission ratio, the material of the flexible plate and the pressure can be adjusted according to the thickness and material of the paper, thereby improving the adaptability of the equipment to various operating conditions. The sliding plate, the side baffle plate and the clamping mechanism in the design work together to not only firmly clamp the two sides of the paper stack, effectively prevent the paper stack from tilting or collapsing, but also protect the paper from pollution and damage from the external environment such as wind or dust through the uniform pressure applied by the flexible plate.
