Description

Technical Field

[0001] This utility model relates to the field of adjustment seat technology, and in particular to a novel guide roller adjustment seat. Background Technology

[0002] In industrial equipment such as printing presses and slitting machines, guide rollers are core components for conveying materials, and their positional accuracy directly affects the stability of material transmission and processing quality. Therefore, the guide roller adjusting seat, as a key device for realizing guide roller position adjustment, has a significant impact on equipment performance.

[0003] Currently, common guide roller adjustment seats on the market mainly suffer from the following technical defects: First, traditional adjustment seats mostly adopt complex transmission structures such as gears and connecting rods, resulting in a large overall size, high installation space requirements, and significantly increased manufacturing costs; Second, assembly methods mostly rely on welding or flange connections, which not only takes time to install (usually more than 10 minutes), but also makes disassembly and maintenance difficult and cannot be reused; Third, the adjustment accuracy is insufficient, and the adjustment amount is mostly judged by manual experience, making it difficult to achieve synchronous adjustment at both ends of the guide roller (the error can reach more than 0.5mm), which easily leads to the tilting of the guide roller and affects the straightness of material conveying; Fourth, the adjustment process lacks intuitive scale indications, and operators need to repeatedly measure and calibrate, resulting in low adjustment efficiency and poor consistency.

[0004] Therefore, there is an urgent need for a new type of guide roller adjustment seat that is simple and compact in structure, reliable in assembly, precise in adjustment, and has intuitive scale indication, so as to meet the high efficiency and high precision requirements of industrial equipment for guide roller position adjustment. Utility Model Content

[0005] The main technical problem solved by this utility model is to provide a novel guide roller adjustment seat, which solves one or more of the above-mentioned problems in the prior art.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a novel guide roller adjusting seat, the innovation of which is: including a fixed shaft, an eccentric assembly and an adjusting nut; the fixed shaft has a positioning structure for assembly with the frame at its end and an assembly groove at its head end; the eccentric assembly includes an adjusting bolt that mates with the assembly groove, an eccentric seat connected to the front end of the adjusting bolt, and an eccentric shaft disposed on the front side of the eccentric seat; the adjusting nut is sleeved on the adjusting bolt, and its outer wall is provided with a scale for displaying the extension distance of the adjusting bolt.

[0007] In some embodiments, the positioning structure includes a positioning hole formed on the end face of the fixed shaft, and a positioning screw that mates with the positioning hole, wherein the positioning hole is coaxially arranged with the fixed shaft.

[0008] In some implementations, the outer wall of the eccentric seat is provided with anti-slip grooves.

[0009] In some embodiments, the assembly slot is provided with an internal adjusting thread, and the adjusting bolt is threadedly connected to the assembly slot through the internal adjusting thread.

[0010] In some implementations, the 0 mark on the dial corresponds to the position when the adjusting nut is fully inserted into the assembly slot, and the scale value changes linearly with the extension distance of the adjusting bolt.

[0011] In some implementations, the eccentric shaft and the guide roller are fixed together by shaft holes, and the centers of the eccentric shaft and the fixed shaft are not on the same axis, forming a radial eccentricity.

[0012] In some implementations, the eccentricity ranges from 0.5 to 5 mm, depending on the required precision of the guide roller adjustment.

[0013] In some implementations, an anti-loosening washer is provided between the adjusting nut and the adjusting bolt to lock the adjusted position.

[0014] In some implementations, the fixed shaft, eccentric seat, and adjusting nut are all made of stainless steel or aluminum alloy.

[0015] In some implementations, the adjusting seats are arranged in pairs at both ends of the guide roller, and the guide roller is precisely and synchronously adjusted by rotating the adjusting nuts on both sides simultaneously.

[0016] The beneficial effects of this utility model are: convenient and reliable assembly: through the cooperation of positioning holes and positioning screws, the assembly of the fixed shaft and the frame only takes 1-2 minutes, and it can be disassembled and reused; the setting of anti-loosening shims avoids positional displacement caused by vibration after adjustment, improving reliability by 30%; compact structure and low cost: the core components only include the fixed shaft, eccentric component and adjusting nut, without complex transmission parts, the overall volume is reduced by 50% compared with the traditional adjusting seat, and the manufacturing cost is reduced by 25%; precise synchronous adjustment: when the adjusting seats are set in pairs at both ends of the guide roller, the scale on both sides can display the adjustment amount synchronously.

[0020] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] like Figure 1 and Figure 2 As shown, the embodiment of this utility model includes: a novel guide roller adjusting seat, mainly used for precise position adjustment of the guide roller, suitable for equipment such as printing presses and slitting machines that require guide roller positioning. Its core structure includes a fixed shaft 100, an eccentric assembly, and an adjusting nut 300. The following is a detailed description of the specific structure of each component:

[0022] The fixed shaft 100 is a cylindrical metal rod (preferably made of stainless steel or aluminum alloy, balancing strength and corrosion resistance). Its end (the end away from the guide roller) is provided with a positioning structure for assembly with the frame. Specifically, the positioning structure is a circular positioning hole 101 (the diameter matches the positioning screw 102, and the depth is 1 / 3 of the diameter of the fixed shaft 100) coaxially opened on the end face of the fixed shaft 100. The positioning screw 102 passes through the positioning hole 101 and is screwed into the pre-set threaded hole of the frame, so as to achieve reliable assembly of the fixed shaft 100 and the frame (this design simplifies the complex process of traditional welding or flange connection, and improves the assembly efficiency by more than 40%). The head end of the fixed shaft 100 (the end near the guide roller) is provided with a cylindrical assembly groove 103. The inner wall of the assembly groove 103 is machined with an internal adjusting thread (the pitch is 1mm, which is adapted to the external thread of the adjusting bolt 201).

[0023] The eccentric assembly is the core component for adjusting the guide roller, including an adjusting bolt 201, an eccentric seat 202, and an eccentric shaft 203. The adjusting bolt 201 is a threaded rod (its diameter matches the inner diameter of the mounting groove 103, and its length is 1.5 times the depth of the mounting groove 103), and its end is threadedly connected to the mounting groove 103 via an internal adjusting thread. The front end of the adjusting bolt 201 (the end furthest from the fixed shaft 100) is integrally formed with the eccentric seat 202, which is a disc-shaped structure (its diameter is 2mm larger than that of the adjusting bolt 201 for easy manual operation), and its outer wall... Four anti-slip grooves 204 (0.5 mm deep, 1 mm wide) are evenly distributed around the circumference to increase the friction between the hand and the eccentric seat 202 and prevent slippage during adjustment. An eccentric shaft 203 is provided on the front side of the eccentric seat 202 (the side away from the adjusting bolt 201). The eccentric shaft 203 is a cylindrical shaft (the diameter matches the shaft holes at both ends of the guide roller). Its center has a radial eccentricity with the center of the fixed shaft 100 (the eccentricity is 2 mm in this embodiment, which can be adjusted to 0.5-5 mm according to equipment requirements). This design is the key to realizing the adjustment of the guide roller position.

[0024] The adjusting nut 300 is a ring-shaped metal part (material consistent with the fixed shaft 100), which is sleeved on the adjusting bolt 201 and threadedly engaged with the adjusting bolt 201. The outer wall of the adjusting nut 300 is engraved with a ring-shaped scale (scale accuracy of 0.1mm). When the adjusting nut 300 is fully screwed into the assembly groove 103, the 0 mark on the scale is flush with the end face of the assembly groove 103. As the adjusting bolt 201 is screwed outward, the scale value of the scale increases linearly (e.g., when the adjusting bolt 201 extends 1mm, the scale points to 1.0), which can intuitively display the adjustment amount. An anti-loosening washer (using a spring washer, 1mm thick) is also provided between the adjusting nut 300 and the adjusting bolt 201 to lock the adjusted position and prevent the adjustment amount from shifting due to equipment vibration.

[0025] The working principle of this technical solution is as follows: The working principle of this adjusting seat is based on a dual adjustment mechanism of "radial displacement of eccentric shaft 203" and "thread fine adjustment":

[0026] When the position of the guide roller needs to be adjusted, firstly, the eccentric seat 202 is rotated (using the anti-slip groove 204 to increase friction) to make the eccentric shaft 203 rotate around the center of the fixed shaft 100. Since the eccentric shaft 203 is not coaxial with the fixed shaft 100 (there is a 2mm eccentricity), when the eccentric seat 202 is rotated, the eccentric shaft 203 will generate radial displacement (the maximum displacement is twice the eccentricity, i.e., 4mm), thereby driving the guide roller to move as a whole and achieving coarse adjustment.

[0027] After the coarse adjustment is completed, by rotating the adjusting nut 300, the adjusting bolt 201 is engaged with the assembly groove 103 by the thread (1mm pitch), so that the adjusting bolt 201 extends or retracts slightly along the axial direction (the adjustment amount is 1mm per rotation). With the help of the 0.1mm precision scale on the dial, the position of the guide roller can be precisely adjusted (minimum adjustment amount 0.1mm).

[0028] The advantages of this technical solution are:

[0029] Easy and reliable assembly: By using the positioning hole 101 and positioning screw 102, the assembly of the fixed shaft 100 and the frame only takes 1-2 minutes (traditional welding takes more than 10 minutes), and it can be disassembled and reused; the anti-loosening shim avoids positional displacement caused by vibration after adjustment, improving reliability by 30%.

[0030] Compact and low-cost structure: The core components include only the fixed shaft 100, the eccentric assembly and the adjusting nut 300, without complex transmission parts (such as gears and connecting rods). The overall volume is reduced by 50% compared with the traditional adjusting seat, and the manufacturing cost is reduced by 25%.

[0031] Precision synchronous adjustment: When the adjustment seats are set in pairs at both ends of the guide roller, the scales on both sides can display the adjustment amount synchronously (error ≤ 0.1mm). By synchronously rotating the adjustment nuts on both sides by 300, it can be ensured that the adjustment amount at both ends of the guide roller is consistent, avoiding the guide roller from tilting (the error of the traditional adjustment method can reach more than 0.5mm).

[0032] This novel guide roller adjusting seat achieves coarse adjustment through the radial displacement of the eccentric shaft 203, combined with the threaded fine adjustment and scale indication of the adjusting nut 300, thus balancing adjustment efficiency and accuracy. Its compact structural design and convenient assembly method significantly reduce equipment maintenance costs and are suitable for industrial scenarios with high requirements for guide roller position accuracy.
