Description

Technical Field

[0001] The present invention belongs to the technical field related to paper stacking supports, and more 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 printers, often also called the print output support or print paper collection tray, is an accessory designed specifically for printers. Its main purpose is to better manage and collect printed paper, ensuring that print jobs can be output neatly and orderly, and preventing paper from being scattered or messed up. However, the paper stacking support in the prior art has the following defects:

[0003] 1. In the prior art, the paper stacking stand uses a simple stand to place the paper stack, but the simple stand 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 of preparing printing materials, and reduces the overall work efficiency.

[0004] 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 handling may cause scratches to the paper or operators;

[0005] 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, causing local deformation or damage. In addition, there is no side support, and the overall stability of the paper stack is poor. Even slight vibrations may cause the paper to be misplaced or scattered, which is not conducive to the orderly management of documents.

[0006] Therefore, in view of this, the existing structure and defects are studied and improved, and a paper stacking support assembly for a printing press with an adjustment function is provided, in order to achieve a more practical and valuable purpose. Summary of the Invention

[0007] The present invention provides a paper stacking support assembly for a printing press with an adjustment function, which is used to overcome the above-mentioned defects in the prior art.

[0008] The purpose and effect of the paper stacking support assembly for a printing press with an adjustable function of the present invention are achieved by the following specific technical means:

[0009] The cam is provided with a plurality of guide rails, and the guide rails are provided with a plurality of guide rails, and the guide rails are provided with a plurality of guide rails.

[0010] According to a further technical solution, a winding rope is provided at one end of the limiting rod, and a first transmission belt is provided at the other end of the limiting rod which passes through the rear box and is connected to the connecting rod.

[0011] According to a further technical solution, two vertical poles are symmetrically provided 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.

[0012] According to a further technical solution, a pull rope is provided on the surface of the pulley for sliding, 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.

[0013] A further technical solution is that the fixing device includes a protective top plate, a plurality of annular mounting brackets 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 annular mounting brackets, a rotating shaft is connected between the plurality of annular mounting brackets and the plurality of folding plates, and an outer end rod is connected to one end of the rotating shaft.

[0014] A further technical solution is that the protective top plate surface array is provided with four sliding rods, the four sliding rods are arranged on the outside of the annular mounting frame, a movable plate is slidingly provided between the four sliding rods, 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 array is provided with several extrusion springs, and a flexible plate is connected to the surface of several extrusion springs.

[0015] According to a further technical solution, a second transmission belt is provided to connect the outer end rod and the connecting rod.

[0016] According to a further technical solution, sliding grooves are symmetrically provided on both sides of the lower shell, and the sliding grooves are in contact with the sliding plate.

[0017] 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.

[0018] 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 surfaces of the pads are in contact with the surface of the contact plate.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 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, when a cardboard stacking device is placed on the surface, the pad at the bottom of the tray will contact the surface of the 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 applies tension to the pull rope when it descends. After the pull rope senses the tension, it prompts 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. During this process, the inward tightening of the sliding plate causes the symmetrically arranged side guards on both sides to move inward simultaneously, 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 handling, transportation or storage, thereby improving the stability of the overall operation. In addition, the precise and uniform clamping force can reduce friction and collision between cardboards, reducing the risk of damage to the edge or surface of the cardboard during operation. This is especially important for materials that are fragile or need to maintain flatness.

[0021] The present invention discloses an adjustable paper stacking support assembly for a printing press. When a connecting rod rotates, a second transmission belt mounted on its surface drives the outer end rod to rotate. The rotation of the outer end rod then causes the rotating shaft to rotate, guiding the folding plate to fold and extend. During this process, the movement of the folding plate drives the movable plate to slide along the surface of the slide rod. Of particular note, once the outer end rod receives rotational force, the movable plate applies downward pressure. At this point, a flexible plate mounted on the surface of the compression spring compresses the topmost sheet of paper, preventing damage from wind or dust during placement or operation, thereby ensuring the integrity of the paper. Furthermore, the specially designed compression mechanism, which utilizes the flexible plate to compress the paper, effectively prevents contamination and damage from external factors such as wind and dust. This is particularly important for keeping the paper clean and preventing damage, especially when used outdoors or in dusty environments. Furthermore, the mechanical structure can be adjusted to accommodate different paper thicknesses or materials by varying the transmission ratio, the material of the flexible plate, or the pressure applied, thereby increasing the versatility and adaptability of the device.

[0022] A paper stack support assembly for a printing press with an adjustable function, utilizing a complex mechanical structure consisting of connecting rods, a transmission belt, an outer end rod, and a rotating shaft, achieves automatic adjustment of the paper stack support. The transmission ratio, flexible plate material, and pressure can be adjusted according to paper thickness and material, improving the device's adaptability to various operating conditions. The sliding plates, side guards, and clamping mechanism in the design work together to not only firmly clamp the two sides of the paper stack, effectively preventing it from tilting or collapsing, but also protect the paper from contamination and damage from external factors such as wind and dust through the uniform pressure exerted by the flexible plates. This makes it particularly suitable for paper handling applications requiring high flatness and cleanliness. Furthermore, the integrated mechanical linkage design simplifies the operation process, allowing users to quickly load, secure, and protect the paper stack with simple controls, improving work efficiency while reducing operator workload. Precisely controlling the clamping force of the paper reduces unnecessary friction and collision between sheets of paper, effectively minimizing the risk of damage to the edges or surfaces of the sheets during handling and ensuring the quality of the final printed product.

[0051] Specific use of the present invention:

[0052] When using the present invention, it is first placed in a designated location in the workshop. The process then proceeds as follows: Printing paper is stacked one by one on the tray until it reaches a predetermined thickness. At this point, the loaded tray is carefully moved onto the device using a forklift. Before placing the tray, ensure that the pads 18 at the bottom of the tray fit precisely into the notches on the thickened protective cover 17. Once the pads are aligned accurately, the tray is slowly lowered.

[0053] Once the tray is securely in place, the built-in securing mechanism 12 and the cardboard stacking mechanism 14 activate, working together to securely hold the paper stack. Specifically, the pad 18 at the bottom of the tray contacts the contact plate 46, generating pressure that causes the contact plate 46 to sink. As the contact plate 46 descends, it pulls the attached pull cord 30, which in turn rotates the winding cord 36 counterclockwise. This rotation of the winding cord 36 triggers the rotation of the limit rod 26, which is held in place by the limit spring 35 during this process, ensuring stable movement. The connecting rod 27 then rotates, driving the sliding plate 32 inward via the slider 47 on it. Simultaneously, the side guards 21 on either side retract inward, securing the paper stack securely.

[0054] Furthermore, the rotation of connecting rod 27 transmits power to outer end rod 38 via second drive belt 29, triggering rotation of shaft 43, which in turn drives folding plate 42 to telescope and fold. This movement, via movable plate 40, slides along slide bar 39, applying gentle pressure to the top layer of paper. Flexible plate 45 protects the paper from external factors such as wind and dust. To move the stack, simply trigger the release mechanism of limit spring 35, unlocking it. The stack can then be safely lifted and moved using a forklift. The entire process is smooth and efficient, with meticulous attention to detail.

[0055] 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, when a cardboard stacking device is placed on the surface, the pad at the bottom of the tray will contact the surface of the 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 applies tension to the pull rope when it descends. After the pull rope senses the tension, it prompts 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. During this process, the inward tightening of the sliding plate causes the symmetrically arranged side guards on both sides to move inward simultaneously, 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 handling, transportation or storage, thereby improving the stability of the overall operation. In addition, the precise and uniform clamping force can reduce friction and collision between cardboards, reducing the risk of damage to the edge or surface of the cardboard during operation. This is especially important for materials that are fragile or need to maintain flatness.

[0056] The present invention discloses an adjustable paper stacking support assembly for a printing press. When a connecting rod rotates, a second transmission belt mounted on its surface drives the outer end rod to rotate. The rotation of the outer end rod then causes the rotating shaft to rotate, guiding the folding plate to fold and extend. During this process, the movement of the folding plate drives the movable plate to slide along the surface of the slide rod. Of particular note, once the outer end rod receives rotational force, the movable plate applies downward pressure. At this point, a flexible plate mounted on the surface of the compression spring compresses the topmost sheet of paper, preventing damage from wind or dust during placement or operation, thereby ensuring the integrity of the paper. Furthermore, the specially designed compression mechanism, which utilizes the flexible plate to compress the paper, effectively prevents contamination and damage from external factors such as wind and dust. This is particularly important for keeping the paper clean and preventing damage, especially when used outdoors or in dusty environments. Furthermore, the mechanical structure can be adjusted to accommodate different paper thicknesses or materials by varying the transmission ratio, the material of the flexible plate, or the pressure applied, thereby increasing the versatility and adaptability of the device.

[0057] A paper stack support assembly for a printing press with an adjustable function, utilizing a complex mechanical structure consisting of connecting rods, a transmission belt, an outer end rod, and a rotating shaft, achieves automatic adjustment of the paper stack support. The transmission ratio, flexible plate material, and pressure can be adjusted according to paper thickness and material, improving the device's adaptability to various operating conditions. The sliding plates, side guards, and clamping mechanism in the design work together to not only firmly clamp the two sides of the paper stack, effectively preventing it from tilting or collapsing, but also protect the paper from contamination and damage from external factors such as wind and dust through the uniform pressure exerted by the flexible plates. This makes it particularly suitable for paper handling applications requiring high flatness and cleanliness. Furthermore, the integrated mechanical linkage design simplifies the operation process, allowing users to quickly load, secure, and protect the paper stack with simple controls, improving work efficiency while reducing operator workload. Precisely controlling the clamping force of the paper reduces unnecessary friction and collision between sheets of paper, effectively minimizing the risk of damage to the edges or surfaces of the sheets during handling and ensuring the quality of the final printed product.
