Description

Technical Field

[0001] This utility model relates to the field of paper receiving machines, specifically a paper receiving machine deceleration paper receiving mechanism. Background Technology

[0002] Paper collecting machines are widely used equipment in industries such as printing and packaging. They are mainly used to collect, sort, stack, and pack paper from the production line. Paper collecting machines are widely used in paper product processing industries such as printing plants, packaging plants, and cardboard box factories, and play an important role, especially in production lines that require efficient and stable processing of large quantities of paper.

[0003] Existing paper receiving machines require a deceleration receiving mechanism to slow down the paper during the receiving process. This mechanism uses a rotating shaft and pressure rollers, with a motor driving the rollers to rotate at a reduced speed under the action of a reducer, thus slowing down the paper's movement. The pressure rollers in the existing receiving mechanism are fixed with bolts, requiring the manipulation of multiple bolts for disassembly and assembly. Since there are multiple pressure rollers, removing multiple bolts is cumbersome when replacement is needed due to damage, and the limited operating space also hinders quick disassembly. Therefore, a new technical solution is needed to address this issue. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a deceleration paper receiving mechanism for paper receiving machines to solve the technical problems of the current cumbersome operation of disassembling multiple bolts, as well as the limited operating space and the inconvenience of quick disassembly.

[0005] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: a paper receiving machine deceleration paper receiving mechanism, a fixed frame, a rotating roller rotatably installed on the inner wall of the fixed frame, a reducer fixed at one end of the fixed frame, a servo motor fixedly installed on the outer wall of the reducer, the transmission shaft of the servo motor and the input shaft of the reducer fixedly connected, the output shaft of the reducer movably passing through the fixed frame and fixedly connected to one end of the rotating roller, and also including a horizontal plate, the horizontal plate being fixed to the upper side of the inner wall of the fixed frame, a lifting plate being provided on the lower side of the horizontal plate, a driving assembly being installed on the top of the horizontal plate, the driving assembly being used to drive the lifting plate to rise and fall, a plurality of evenly distributed retainers being installed at the bottom of the lifting plate, pressure rollers being rotatably installed inside the retainers, a limit plate being fixedly connected to the top of the retainers, a limit slot being opened on the side wall of the lifting plate, and the limit plate being inserted into the limit slot.

[0006] Specifically, a servo motor drives the rotating roller to rotate, thereby driving the paper to move. At the same time, an electric push rod drives the lifting plate to descend, so that the pressure roller is in contact with the paper surface and applies slight pressure, thus ensuring stable paper movement. When the pressure roller is damaged and needs to be replaced, the limit plate can be directly pulled out from the limit slot, which improves the convenience of operation and avoids the limitation of operating space.

[0007] Preferably, the top of the lifting plate is provided with an installation groove, and the installation groove is connected to the limiting slot. A limiting component is fixedly installed in the installation groove. The limiting component includes a fixed shell, which is fixedly installed in the installation groove. A lifting column is movably inserted through one side of the top of the fixed shell, and a positioning column is movably inserted through one side of the bottom of the fixed shell. A spring is fixedly installed on the top of the positioning column, and the top of the spring is fixedly connected to the top of the inner cavity of the fixed shell. A fixing rod is fixedly installed on one side of the outer wall of the positioning column. A rotating shaft is rotatably installed on the inner side wall of the fixed shell. A movable plate is fixedly fitted on the outer wall of the rotating shaft. A positioning hole is provided on the top of the limiting plate corresponding to the positioning column.

[0008] Specifically, during the installation of the pressure roller, the drive assembly raises the lifting plate, which in turn presses the lifting column against the horizontal plate, causing the lifting column to descend. This, in turn, rotates the movable plate, causing one end of the movable plate to descend while the other end rises, pushing the fixed rod to rise. This causes the positioning column to rise and compress the spring, allowing unobstructed insertion of the limit plate. When the pressure roller needs to be lowered for use, the lifting column is no longer compressed, and the spring pushes the positioning column downward to insert it into the positioning hole at the top of the limit plate, thus limiting the position of the limit plate and improving its stability after insertion. When disassembly is required, raising the lifting plate to the bottom of the horizontal plate causes the lifting column to press down, which in turn raises the positioning column, releasing the limit plate. The pressure roller can then be removed by directly pulling out the limit plate, further enhancing the ease of assembly and disassembly.

[0009] Preferably, the drive assembly includes an electric actuator, which is fixedly installed on the top of the horizontal plate, and the actuator rod moves through the horizontal plate and is fixedly connected to the top of the lifting plate.

[0010] Specifically, the electric actuator can drive the lifting plate to rise and fall, thereby driving the pressure roller to rise and fall, so that the pressure roller can press on the paper surface during use.

[0011] Preferably, the bottom of the positioning post is chamfered.

[0012] Preferably, limit rods are fixedly connected to both sides of the top of the lifting plate, and the limit rods movably pass through the horizontal plate.

[0013] Specifically, the limit rod is designed to limit the lifting trajectory during the process of the electric actuator driving the lifting plate, thereby improving the stability of the lifting process.

[0014] Preferably, mounting plates are fixedly installed on both sides of the fixing frame, and mounting holes are opened on both sides of the surface of the mounting plates.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model connects the pressure roller and the lifting plate by inserting a limiting plate and a limiting slot, which makes disassembly and assembly convenient and quick, and improves the convenience of replacing the pressure roller if it is damaged. Furthermore, the positioning column is pushed down by a spring so that it can be inserted into the positioning hole, which helps to improve the stability of the pressure roller after connection.

[0017] 2. This utility model uses an electric actuator to lift the lifting plate, which causes the lifting column to be squeezed by the horizontal plate. This causes the lifting column to push one end of the movable plate down, which in turn lifts the other end of the movable plate, thereby lifting the fixed rod and the positioning column. This allows the positioning column to disengage from the positioning hole and be directly removed from the limiting plate, thus further improving the convenience of disassembling and assembling the pressure roller.

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0027] Example 1: Paper delivery machine deceleration paper delivery mechanism, see [link / reference] Figures 1 to 5 The device includes a fixed frame 1, a rotating roller 11 rotatably mounted on the inner wall of the fixed frame 1, a reducer 12 fixed at one end of the fixed frame 1, a servo motor 13 fixedly mounted on the outer wall of the reducer 12, a drive shaft of the servo motor 13 fixedly connected to the input shaft of the reducer 12, and an output shaft of the reducer 12 movably passing through the fixed frame 1 and fixedly connected to one end of the rotating roller 11.

[0028] Specifically, the servo motor 13 drives the rotating roller 11 to rotate via the reducer 12, thereby reducing the speed of the rotating roller 11 and thus driving the paper to decelerate.

[0029] It also includes a horizontal plate 2, which is fixed to the upper side of the inner wall of the fixed frame 1. A lifting plate 3 is provided on the lower side of the horizontal plate 2. A drive assembly is installed on the top of the horizontal plate 2. The drive assembly is used to drive the lifting plate 3 to rise and fall. Multiple evenly distributed retainers are installed at the bottom of the lifting plate 3. A pressure roller 31 is rotatably installed inside the retainer. A limit plate 32 is fixedly connected to the top of the retainer. A limit slot is opened on the side wall of the lifting plate 3. The limit plate 32 is inserted into the limit slot.

[0030] It should be understood that in actual use, the servo motor 13 drives the rotating roller 11 to rotate, thereby driving the paper to move. At the same time, the electric push rod 21 drives the lifting plate 3 to descend, so that the pressure roller 31 is in contact with the paper surface and applies slight pressure, thereby ensuring stable paper movement. When the pressure roller 31 is damaged and needs to be replaced, the limit plate 32 can be directly pulled out from the limit slot, which helps to improve the convenience of operation and avoid the limitation of operating space.

[0031] Furthermore, mounting plates 14 are fixedly installed on both sides of the mounting frame 1. Mounting holes are provided on both sides of the surface of the mounting plates 14. The mounting plates 14 and the mounting holes facilitate the installation and fixing of the entire device.

[0032] like Figure 1-4As shown, the top of the lifting plate 3 is provided with an installation groove, and the installation groove is connected to the limiting slot. A limiting component is fixedly installed in the installation groove. The limiting component includes a fixed shell 33, which is fixedly installed in the installation groove. A lifting column 34 is movably inserted through one side of the top of the fixed shell 33, and a positioning column 35 is movably inserted through one side of the bottom of the fixed shell 33. A spring 38 is fixedly fixed to the top of the positioning column 35, and the top of the spring 38 is fixedly connected to the top of the inner cavity of the fixed shell 33. A fixing rod 39 is fixedly fixed to one side of the outer wall of the positioning column 35. A rotating shaft 36 is rotatably installed on the inner side wall of the fixed shell 33. A movable plate 37 is fixedly fitted on the outer wall of the rotating shaft 36. A positioning hole is provided on the top of the limiting plate 32 corresponding to the positioning column 35.

[0033] It should be understood that in actual use, when installing the pressure roller 31, the drive assembly drives the lifting plate 3 to rise, thereby pressing the lifting column 34 against the horizontal plate 2, causing the lifting column 34 to descend. This causes the movable plate 37 to rotate, with one end of the movable plate 37 descending and the other end rising, which in turn pushes the fixed rod 39 to rise. This causes the positioning column 35 to rise and compress the spring 38. At this time, there is no obstruction when inserting the limiting plate 32. Then, when it is necessary to lower the pressure roller 31 for use, the lifting column 34 is not compressed, and the spring 38 pushes the positioning column 35 down to insert into the top of the limiting plate 32. The limit plate 32 is positioned within the hole, thereby improving the stability of the limit plate 32 after insertion. When disassembly is required, the lifting plate 3 is raised to the bottom of the horizontal plate 2, causing the lifting column 34 to be pressed down by the fixed horizontal plate 2. Similarly, under the rotation of the movable plate 37, the fixing rod 39 is lifted, which allows the positioning column 35 to be lifted and disengaged from the positioning hole, thereby releasing the limit plate 32. The limit plate 32 can then be directly pulled out from the limit slot, and the pressure roller 31 can be quickly disassembled, further improving the ease of disassembly and assembly.

[0034] Furthermore, the bottom of the positioning post 35 is chamfered. The chamfer allows the outer wall of the chamfer to abut against the edge of the positioning hole when the positioning post 35 is inserted into the positioning hole, thereby ensuring the fit of the positioning and improving the stability of the positioning.

[0035] Furthermore, when the positioning post 35 experiences slight wear after long-term use, the outer diameter of the chamfer gradually increases from bottom to top, thereby automatically fitting the part to the edge of the positioning hole, which helps to avoid the situation of wobbling due to gaps.

[0036] like Figure 1 As shown, the drive assembly includes an electric actuator 21, which is fixedly installed on the top of the horizontal plate 2. The actuator 21 moves through the horizontal plate 2 and is fixedly connected to the top of the lifting plate 3.

[0037] It should be understood that the electric actuator 21 can drive the lifting plate 3 to rise and fall, thereby driving the pressure roller 31 to rise and fall, so that the pressure roller 31 can press on the paper surface during use.

[0038] Furthermore, limit rods 22 are fixedly connected to both sides of the top of the lifting plate 3. The limit rods 22 move through the horizontal plate 2. The setting of the limit rods 22 allows the lifting trajectory to be limited by the limit rods 22 during the process of the electric push rod 21 driving the lifting plate 3 to rise and fall, which helps to improve the stability of the lifting.

[0039] It should be noted that the reducer is specifically a gear reducer.
