Description

Technical Field

[0001] This utility model belongs to the technical field of water-based ink printing machines, and more specifically, it relates to a servo paper-pulling roller for a water-based ink printing machine. Background Technology

[0002] In water-based ink printing presses, the servo paper feed roller is a core functional component for pulling flexible materials such as paper. Its technical principles and structural design directly affect printing accuracy and production efficiency. Existing water-based ink printing presses primarily use servo motors to provide power output, driving the output shaft to rotate, which in turn synchronously drives multiple paper feed rollers to rotate in tandem. A high-elasticity rubber wheel, typically made of polyurethane or silicone rubber, is fitted around the outer edge of the paper feed roller. The friction between the rubber wheel surface and the paper creates a stable traction force, enabling continuous and precise material transport.

[0003] Existing application number CN202022931713.3 discloses a paper feed roller anti-warping structure, including a conveyor roller connected between frames. The upper end of the conveyor roller is provided with several sets of paper feeding rollers. The outer diameter of the middle paper feeding roller is smaller than the outer diameter of the two outer paper feeding rollers. A left bearing seat and a right bearing seat are respectively provided on the left and right sides of the frame. A first deep groove ball bearing is provided in the left bearing seat, and a second deep groove ball bearing is provided in the right bearing seat. The two ends of the conveyor roller pass through the first and second deep groove ball bearings respectively. This invention, by having the outer diameter of the middle paper feeding roller smaller than that of the two outer paper feeding rollers, effectively prevents the paperboard from warping during full-page printing and also solves the contact problem between the middle paper feeding roller and the printing surface, thus improving the printing effect.

[0004] Based on the above, the existing servo paper-pulling rollers and rubber rollers of water-based ink printing machines are prone to wear and aging during long-term use, requiring regular maintenance and replacement to maintain elasticity and friction. However, during the replacement of the rubber rollers, it is necessary to manually expand the rubber rollers before fitting them into the outer groove of the paper-pulling roller. Due to the large thickness of the rubber rollers, the expansion and fitting process is laborious and time-consuming; moreover, forced expansion will cause deformation of the rubber rollers, making it difficult to accurately fit into the groove. Often, workers need to use a small wooden hammer to repeatedly tap the rollers to assist in positioning, making the operation process cumbersome and complicated. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a servo paper-pulling roller for a water-based ink printing machine. This solves the problem that existing servo paper-pulling rollers in water-based ink printing machines are prone to wear and aging during long-term use, requiring regular maintenance and replacement to maintain elasticity and friction. However, during the replacement process, the rubber roller needs to be manually expanded before being fitted into the outer groove of the paper-pulling roller. Due to the significant thickness of the rubber roller, the expansion and fitting process is laborious and time-consuming; furthermore, forced expansion can cause deformation of the rubber roller, making it difficult to accurately fit into the groove. Often, operators need to repeatedly tap the roller with a small wooden hammer to assist in positioning, resulting in a cumbersome and complex operation.

[0006] The purpose and function of this utility model of a servo paper-pulling roller for a water-based ink printing machine are achieved by the following specific technical means:

[0007] A servo paper feed roller for a water-based ink printing machine includes a paper feed roller body, a slot, a rubber wheel, a knob, a limit baffle, a maintenance component, and a limit component. The slot is located on the outside of the paper feed roller body; the rubber wheel is installed inside the slot; the knob is rotatably connected inside the paper feed roller body; multiple sets of limit baffles are arranged in a circumferential array inside the paper feed roller body; the maintenance component is located inside the paper feed roller body; and the limit component is located inside the paper feed roller body.

[0008] Furthermore, the maintenance component includes a card holder, which is fixedly installed on the outside of the paper puller body.

[0009] Furthermore, the maintenance component also includes: a first sliding groove and a connecting rod, wherein multiple sets of the first sliding groove are provided, the multiple sets of the first sliding groove are opened inside the paper puller body, and the multiple sets of the first sliding groove are slidably connected to the limiting baffles inside; multiple sets of the connecting rod are provided, and the top ends of the multiple sets of the connecting rod are hinged inside the multiple sets of limiting baffles.

[0010] Furthermore, the maintenance component also includes a drive threaded ring and a transmission ring. The drive threaded ring is fixedly installed inside the knob and rotatably connected inside the paper puller body. The transmission ring is threadedly connected to the outside of the drive threaded ring and is hinged to the end of multiple sets of connecting rods.

[0011] Furthermore, the limiting component includes: a second sliding groove and an elastic element. The second sliding groove is provided in multiple sets, and the multiple sets of the second sliding groove are opened inside the multiple sets of limiting baffles. The elastic element is provided in multiple sets, and one end of the multiple sets of the elastic element is fixedly installed inside the multiple sets of the second sliding groove.

[0012] Furthermore, the limiting component also includes: a limiting block and a chamfered surface. The limiting block is provided in multiple sets, and the multiple sets of the limiting block are slidably connected inside the multiple sets of second sliding grooves. The chamfered surface is provided in multiple sets, and the multiple sets of the chamfered surface are formed on one side of the bottom of the limiting block.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] Firstly, this invention features a maintenance component. A screw-driven structure, operated by a knob, converts rotational motion into radial displacement of the limiting baffle, allowing the slot to be opened without manual expansion of the rubber wheel. During replacement, rotating the knob causes the limiting baffle to slide away from the slot along the sliding groove, allowing the rubber wheel to directly engage. Reversing the knob resets the limiting baffle, creating front-to-back constraints with the mounting platform. This avoids the problems of rubber wheel deformation and inaccurate slot fit caused by manual expansion in traditional installations.

[0015] Secondly, this utility model has a limiting component. The elastic element inside the limiting baffle cooperates with the limiting block. When the limiting baffle is closed, the elastic element pushes the limiting block to extend, forming multi-point compression on the outer edge of the rubber wheel, effectively preventing the rubber wheel from generating radial displacement during operation. When disassembling, the chamfered edge at the bottom of the limiting block contacts the inner wall of the sliding groove, automatically triggering the limiting block to retract, avoiding interference and ensuring a smooth disassembly and assembly process.

[0016] This utility model has the advantages of quick maintenance and replacement, convenient use, and stable installation. It simplifies the rubber wheel replacement operation process, reduces maintenance difficulty, enhances the reliability of rubber wheel fixation, reduces printing deviations caused by loose rubber wheels or improper installation, and improves the overall performance and practicality of the servo paper pull roller of the water-based ink printing machine.

[0025] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0026] Example 1:

[0027] As attached Figure 1 To be continued Figure 6 As shown:

[0028] This utility model provides a servo paper puller for a water-based ink printing machine, including a paper puller body 1, a slot 2, a rubber wheel 3, a knob 4, a limiting baffle 5, and a maintenance component. The slot 2 is located on the outside of the paper puller body 1; the rubber wheel 3 is installed inside the slot 2; the knob 4 is rotatably connected inside the paper puller body 1; multiple sets of limiting baffles 5 are arranged in a circumferential array inside the paper puller body 1; and the maintenance component is located inside the paper puller body 1.

[0029] The maintenance components include: a card holder 101, which is fixedly installed on the outside of the paper puller body 1.

[0030] The maintenance components also include: a first sliding groove 102 and a connecting rod 403. The first sliding groove 102 is provided in multiple sets, and the multiple sets of first sliding grooves 102 are opened inside the paper puller body 1. The multiple sets of first sliding grooves 102 are slidably connected to the limit baffles 5 inside. The connecting rod 403 is provided in multiple sets, and the top of the multiple sets of connecting rods 403 is hinged inside the multiple sets of limit baffles 5.

[0031] The maintenance components also include a drive threaded ring 401 and a transmission ring 402. The drive threaded ring 401 is fixedly installed inside the knob 4 and is rotatably connected inside the paper puller body 1. The transmission ring 402 is threadedly connected to the outside of the drive threaded ring 401 and is hinged to the end of multiple sets of connecting rods 403.

[0032] The specific usage and function of this embodiment are as follows:

[0033] When it is necessary to replace or install the rubber wheel 3, rotate the knob 4 in the forward direction. The knob 4 synchronously drives the drive threaded ring 401 fixed inside to rotate within the paper puller body 1. Since the drive threaded ring 401 and the transmission ring 402 are threadedly engaged, the rotation of the drive threaded ring 401 will push the transmission ring 402 to move axially along the paper puller body 1 through the threaded pair. As the transmission ring 402 moves, its hinged multiple sets of connecting rods 403 synchronously generate angular swing, thereby pulling multiple sets of limiting baffles 5 to slide outward along their respective first sliding grooves 102. The first sliding grooves 102 provide guiding constraints for the movement of the limiting baffles 5. When the limiting baffles 5 slide out completely and disengage from the front area of ​​the slot 2, the opening of the slot 2 is fully exposed. At this time, the rubber wheel 3 to be replaced can be placed directly inside the slot 2, and the bottom of the rubber wheel 3 is initially limited by the clamping platform 101 fixed on the outside of the paper puller body 1 to prevent it from sliding radially along the slot 2. After the rubber wheel 3 is placed, rotate the knob 4 in the opposite direction to drive the threaded ring 401 to rotate in the opposite direction and drive the transmission ring 402 to move back. The connecting rod 403 pushes the limiting baffle 5 to reset along the first sliding groove 102 to the front side of the slot 2, forming a front and rear cooperative limiting with the slot 101, and stably constraining the rubber wheel 3 in the slot 2, thus completing the quick installation.

[0034] Example 2:

[0035] Based on Example 1, such as Figures 1 to 6 As shown, it also includes: a limiting component, which is disposed inside the paper puller body 1.

[0036] The limiting component includes: a second sliding groove 501 and an elastic element 502. Multiple sets of second sliding grooves 501 are provided, and multiple sets of second sliding grooves 501 are opened inside multiple sets of limiting baffles 5. Multiple sets of elastic elements 502 are provided, and one end of multiple sets of elastic elements 502 is fixedly installed inside multiple sets of second sliding grooves 501.

[0037] The limiting component also includes: a limiting block 503 and a chamfered surface 504. Multiple sets of limiting blocks 503 are provided, and the multiple sets of limiting blocks 503 are slidably connected inside multiple sets of second sliding grooves 501. Multiple sets of chamfered surfaces 504 are provided, and the multiple sets of chamfered surfaces 504 are formed on one side of the bottom of the limiting block 503.

[0038] The specific usage and function of this embodiment are as follows:

[0039] When the limiting baffle 5 slides outward along the first sliding groove 102 and limits the rubber wheel 3 in the slot 2, the elastic element 502 inside the limiting baffle 5 releases its elastic potential energy due to the loss of external constraint, pushing the limiting block 503 outward along the second sliding groove 501. The second sliding groove 501 provides guidance for the movement of the limiting block 503. The limiting block 503 extends from the inside of the limiting baffle 5 and presses tightly against the outer edge of the rubber wheel 3. Through multi-point elastic compression, the fit between the rubber wheel 3 and the slot 2 is further strengthened, effectively preventing the rubber wheel 3 from radial displacement or loosening due to vibration during high-speed operation.

[0040] When it is necessary to remove the rubber wheel 3, rotating the knob 4 in the forward direction drives the limiting baffle 5 to slide into the first sliding groove 102. At this time, the chamfered edge 504 at the bottom of the limiting block 503 first contacts the inner wall of the first sliding groove 102. During the sliding process, the chamfered edge 504 is squeezed by the groove wall and generates a lateral force, which forces the limiting block 503 to overcome the elastic force of the elastic element 502 and retract into the second sliding groove 501 to hide, so as to avoid interference between the limiting block 503 and the first sliding groove 102 and ensure that the limiting baffle 5 can be smoothly reset and stored.
