Abstract
Description
Technical Field
[0001] This invention belongs to the field of pneumatic balancing technology, specifically relating to a pneumatic balancing device for a paper feeder. Background Technology
[0002] Paper chucks are used in the printing industry to align paper stacks for accurate printing and multi-color overprinting. Depending on the printing requirements, various sizes of paper stacks need to be aligned. Alignment before cutting is an essential step in printing or packaging production. Paper stacks coming off the printing press often don't meet the required neatness; if they go directly to the cutting process, misalignment will occur between the cut products, leading to batch scrap and economic losses. Paper chucks utilize the tilting and vibration of the chuck table to efficiently align paper stacks. After alignment, they automatically remove air from between the papers during the chucking process, ensuring that the paper stacks from the chuck are neat and tight.
[0003] Current paper-breaking machines cannot break up paper stacks of various sizes evenly, have complex structures, low safety, unstable platform rotation, and low production efficiency. Summary of the Invention
[0004] This invention addresses the problems of existing paper-passing machines, such as inability to pass multiple paper stacks of different sizes evenly, complex structure, low safety, unstable platform rotation, and low production efficiency. It proposes a pneumatic balancing device for the paper-passing machine, comprising a platform and a base. The device is characterized by multiple bidirectional cylinders installed between the platform and the base to control the platform's tilt at any horizontal angle; a support column is also installed between the platform and the base to support the platform; the platform is connected to one end of each bidirectional cylinder via an upper universal joint, and the platform is connected to one end of the support column via a universal joint; the base is connected to the other end of each bidirectional cylinder via a lower universal joint, and the base is fixedly connected to the support column; the base is also adjustable in level with the ground.
[0005] According to the above-described pneumatic balancing device for the paper feeder, the bidirectional cylinders are all the same size and are bidirectional cylinders with two ends; the angle between the platform and the horizontal plane is controlled by adjusting the length of each piston rod of the bidirectional cylinder with two ends.
[0006] According to the above-described pneumatic balancing device for the paper feeder, the platform and the base are both square.
[0007] According to the above-described pneumatic balancing device for the paper feeder, the support column is located at the center of the platform. The support column is a hollow column structure with a bottom flange corresponding to the base flange. The bottom flange of the support column and the base flange are fixedly connected to the base by bolts.
[0008] According to the above-described pneumatic balancing device for the paper feeder, the top of the support column is provided with a top flange, which is fixedly connected to the bottom of the universal joint of the support column.
[0009] According to the above-described pneumatic balancing device for the paper feeder, the support column is characterized by having a reinforcing rib structure that connects the support column body with the bottom flange and the top flange of the support column.
[0010] According to the above-described pneumatic balancing device for the paper feeder, the bidirectional cylinders are evenly distributed around the support column; the top piston rods of all bidirectional cylinders are fully extended, and the bottom piston rods of all bidirectional cylinders are fully retracted, so that the platform is in a horizontal state.
[0011] According to the above-described pneumatic balancing device for the paper feeder, the base is characterized by having a through-hole adjusting screw that cooperates with a pad on the ground to adjust the base to a horizontal state.
[0012] According to the above-described pneumatic balancing device for the paper feeder, the upper universal joint of the bidirectional cylinder and the lower universal joint of the bidirectional cylinder have the same dimensions; the dimensions of both the upper and lower universal joints of the bidirectional cylinder are smaller than the universal joint of the support column.
[0013] The pneumatic balancing device for the paper feeder described above is characterized in that there are 3-6 bidirectional cylinders and 4-8 adjusting screws.
[0014] The beneficial effects of the present invention are as follows:
[0015] 1. The pneumatic balancing device of the paper feeder of the present invention is provided with multiple bidirectional cylinders between the platform and the base, which control the platform to tilt at any angle in the horizontal direction. The platform is connected to one end of the bidirectional cylinder through a universal joint on the upper part of the bidirectional cylinder, and the platform is connected to one end of the support column through a universal joint on the support column. The base is connected to the other end of the bidirectional cylinder through a universal joint on the lower part of the bidirectional cylinder. The structure is simple and realizes the control of the paper feeder platform at any angle, and can feed paper stacks of various specifications evenly.
[0016] 2. The paper feeder pneumatic balancing device of the present invention is further provided with a support column between the platform and the base. The support column is provided with a reinforcing rib structure that connects the support column body with the bottom flange and the top flange of the support column, so as to ensure the strength of the platform support when the platform rotates at any angle and improve the safety of the platform.
[0017] 3. In the pneumatic balancing device for the paper feeder of the present invention, the platform and one end of the support column are connected by a support column universal joint. The top of the support column is provided with a support column top flange, which is fixedly connected to the bottom of the support column universal joint. When the universal joint on the bidirectional cylinder rotates, the support column universal joint rotates accordingly, which improves the stability of the platform movement.
[0018] 4. In the pneumatic balancing device of the paper feeder of the present invention, after the top piston rods of all bidirectional cylinders are fully extended and the bottom piston rods of all bidirectional cylinders are fully retracted, the platform is in a horizontal state, which allows the platform to quickly return from an inclined state to a horizontal state, thereby improving the working efficiency and paper feeder quality of the paper feeder.

Detailed Implementation
[0024] Preferred Implementation
[0025] like Figure 1-3 As shown: The pneumatic balancing device for the paper feeder includes a platform 1 and a base 18. Multiple bidirectional cylinders are installed between the platform 1 and the base 18 to control the tilting of the platform at any angle in the horizontal direction. A support column 6 is also installed between the platform and the base to support the platform. The platform 1 is connected to one end of the bidirectional cylinders through a universal joint on the upper part of the bidirectional cylinders, and the platform 1 is connected to one end of the support column 6 through a universal joint on the support column. The base is connected to the other end of the bidirectional cylinders through a lower universal joint on the bidirectional cylinders. The base 18 is fixedly connected to the support column 6. The base 6 is connected to the ground with an adjustable horizontal height.
[0026] All the bidirectional cylinders are the same size, and each is a bidirectional cylinder with two outlets. The angle between the platform and the horizontal plane is controlled by adjusting the length of each piston rod of the bidirectional cylinder with two outlets.
[0027] Both the platform 1 and the base 18 are square.
[0028] The support column 6 is located at the center of the platform. The support column 6 is a hollow column structure with a bottom flange at the bottom, which corresponds to the base flange. The bottom flange of the support column and the base flange are fixedly connected to the base 18 by bolts.
[0029] The top of the support column 6 is provided with a top flange, which is fixedly connected to the bottom of the universal joint of the support column.
[0030] The support column 6 is provided with a reinforcing rib structure that connects the support column body with the bottom flange and the top flange of the support column.
[0031] The bidirectional cylinders are evenly distributed around the support column 6; after the top piston rods of all bidirectional cylinders are fully extended and the bottom piston rods of all bidirectional cylinders are fully retracted, the platform is in a horizontal state.
[0032] The base 18 is provided with a through-hole adjusting screw 16, which cooperates with the pad 17 set on the ground to adjust the base to a horizontal state.
[0033] The upper universal joint and the lower universal joint of the bidirectional cylinder have the same dimensions; the dimensions of both the upper and lower universal joints of the bidirectional cylinder are smaller than those of the support column universal joint.
[0034] There are four bidirectional cylinders; there are four adjusting screws.
[0035] The base 18 is a frame structure, which reduces the weight of the device.
[0036] The extension and retraction of the piston rod of the two-way cylinder is controlled by a hydraulic system.
[0037] The motion process and its working principle:
[0038] like Figure 1 , 2 As shown, the piston rods of the four bidirectional cylinders 5, 7, 11, and 13 are fully extended, and the lower piston rods are fully retracted, keeping platform 1 horizontal.
[0039] like Figure 4 As shown, the piston rods of both ends of the double-ended cylinder 5 extend, the piston rods of both ends of the double-ended cylinder 7 retract, and the double-ended cylinders 11 and 13 remain in place. Figure 2 In this state, platform 1 is tilted to the right; in the same way, platform 1 can tilt to the left, forward, and backward.
[0040] The piston rods of the two-way cylinders 5 and 11 extend outwards, while the piston rods of the two-way cylinders 7 and 13 retract, causing platform 1 to tilt diagonally. In this way, platform 1 can tilt to various angles.
[0041] The aforementioned pneumatic balancing device for the paper feeder has a simple structure, is easy to maintain, and allows the platform to tilt in all directions and quickly return to a horizontal position. It is a safe and reliable balancing mechanism for the paper feeder.
