[0002] The corrugator is a common paper material processing equipment in the food packaging industry, and its performance directly affects the quality and efficiency of paperboard processing. In the production process of food packaging materials, the corrugator realizes uniform conveying and flattening of paper materials through the gap between the paper guide rollers, laying a good foundation for subsequent printing, cutting and other processes.
[0003] However, the existing corrugator technology has some limitations, especially when dealing with high-hardness paper materials such as paperboard for heavy-duty packaging or special purposes, the wear and tear of the paper guide rollers is particularly prominent. The wear and tear of the paper guide rollers not only reduces their service life, but also can cause unevenness in the paper material conveying process, affecting the flattening effect and thus the quality and consistency of the final product.
[0004] The increase of the gap between the paper guide rollers can also cause the paper material to wrinkle, curl or deviate during the conveying process, which is particularly evident on high-speed production lines and can seriously affect the stability and efficiency of the production line. In addition, frequent replacement of the paper guide rollers not only increases material costs, but also causes frequent shutdown of the production line, increases maintenance time and cost, and reduces overall production efficiency. SUMMARY
[0005] The utility model aims at providing a corrugator with floating adjustment function to solve the problem of the corrugator's paper guide roller wear affecting the production quality and efficiency of the product as mentioned in the background.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical scheme:

DETAILED DESCRIPTION
[0025] In order to make the purpose, technical scheme and advantages of the utility model more clear and obvious, the utility model is further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the utility model and do not limit the utility model.
[0026] Example 1, reference Figures 1-4 , a corrugator with floating adjustment function provided by the embodiment, the rack 10 adopts stainless steel material with corrosion resistance and high strength, along the first direction, that is, the feeding to discharging direction of the corrugator, the first paper guide roller set 20 and the second paper guide roller set are sequentially arranged on the rack 10, and the interval at which the first paper guide roller set 20 and the second paper guide roller set are sequentially arranged on the rack 10 can be controlled between 1cm to 3cm to ensure the continuous conveying of paper materials, the first paper guide roller set 20 is composed of two paper guide rollers which are symmetrically arranged above and below, forming a first channel, the two ends of the two paper guide rollers are rotationally connected with the rack 10 and are driven through meshing transmission connection with the motor to ensure the synchronous operation and efficient power transmission of the paper guide rollers, the second paper guide roller set is composed of an upper paper guide roller 301 and a lower paper guide roller 302, and a second channel is formed in the gap, and the width of the second channel is slightly smaller than the thickness of the paper materials to realize a more compact paper material leveling effect.
[0027] The rack 10 is provided with a floating assembly 40, the floating assembly 40 can be elastically matched with the upper paper guide roller 301 or elastically matched with the lower paper guide roller 302, and can automatically float up and down according to the thickness of the paper materials to adjust the width of the second channel.
[0028] In the paper material conveying process, the paper material first passes through the first channel and then enters the second channel formed by the upper paper guide roller 301 and the lower paper guide roller 302. In the second channel, the paper material is in contact with the paper guide rollers, and the self-adaptive adjustment of the channel width is realized by using the thrust generated by the contact. Due to the elastic properties of the floating assembly 40, when the paper material is in contact with the paper guide rollers, the floating assembly 40 generates a reverse elastic force, which ensures that the paper material is in close contact with the paper guide rollers throughout the conveying process, and ensures the flattening effect of the paper material.
[0029] Through the above design, even if the first paper guide roller set 20 is worn during use, the self-adaptive adjustment function of the floating assembly 40 can maintain the flattening effect of the paper material, ensure the product quality is not affected, and also enhance the flexibility and reliability of the entire production line, ensuring that high efficiency and high quality paper material processing can be maintained even in the case of component wear.
[0030] In some embodiments, the upper paper guide roller 301 and the lower paper guide roller 302 can be rotatably arranged on the rack 10. Specifically, mounting holes can be formed on the left and right side walls of the rack 10, which are used to fix bearing seats. The bearing seats are designed with standardized interfaces to adapt to corresponding rotating bearings. The bearing seats can be fixed in the mounting holes by bolts or other fasteners. Rotating bearings suitable for the load and speed requirements of the upper paper guide roller 301 and the lower paper guide roller 302, such as deep groove ball bearings and tapered roller bearings, are installed in the bearing seats to ensure accurate fitting of the bearings with the mounting holes. The installation of the bearings should ensure that their rotation axes are parallel to the axes of the paper guide rollers. The upper paper guide roller 301 and the lower paper guide roller 302 can be machined with shaft necks at both ends that are suitable for fitting with the inner or outer rings of the bearings. These shaft necks can be directly inserted into the inner rings of the bearings or connected to the outer rings of the bearings through shaft sleeves. To ensure the long-term stable operation of the bearings, it is necessary to ensure that the bearings are properly lubricated. The bearing seat design should include lubrication channels and sealing devices to prevent dust and impurities from entering the bearings while maintaining the cleanliness of the lubricating grease.
[0031] The floating assembly 40 can be equipped with a damping device that has elasticity and can stretch and contract when subjected to external force, thereby achieving dynamic adjustment of the gap between the paper guide rollers. The stretching and contracting end of the damping device serves as the movable end of the floating assembly 40 and rotates against the upper paper guide roller 301 and / or the lower paper guide roller 302. This design allows the paper guide rollers to automatically adjust their positions when the paper material passes through.
[0032] When the paper material enters the second channel, it first contacts the upper paper guide roller 301 and the lower paper guide roller 302, which are elastically matched with the floating assembly 40. The paper guide rollers can sensitively respond to the thrust of the paper material. When contact occurs, the corresponding paper guide roller starts to rotate under the action of the thrust of the paper material, and floats up and down. The rotating end of the paper guide roller rotates against the movable end of the floating assembly 40, ensuring continuous contact between the two. The floating assembly 40 elastically deforms under the combined action of the thrust of the paper material and the rotation of the paper guide roller. The elastic properties of the floating assembly 40 cause it to generate a reverse elastic force after deformation. This elastic force ensures that the floating assembly 40 and the paper guide roller always maintain contact. Under the action of the reverse elastic force of the floating assembly 40 and the continuous pressure of the paper guide roller, the paper material is effectively compressed and flattened.
[0033] Through the above design, not only the adaptability and stability of the corrugator are improved, but also the high quality standard of paper material processing is ensured.
[0034] In other embodiments, rotating holes 401 are provided on the movable end of the floating assembly 40. The size and shape of these rotating holes 401 perfectly match the shaft ends of the upper paper guide roller 301 and the lower paper guide roller 302, ensuring that the paper guide rollers can rotate smoothly and be housed in the rotating holes 401. The design of the rotating holes 401 takes into account the stability requirements of the paper guide rollers during high-speed operation. Through precise matching and appropriate bearing support, vibration and wear caused by high-speed rotation are reduced. The rotating holes 401 on the movable end not only provide a rotating connection point, but also, in combination with the elastic properties of the floating assembly 40, allow the paper guide rollers to float as necessary under the action of the thrust of the paper material. Due to the provision of the rotating holes 401, the paper guide rollers can quickly respond to changes in the paper material, achieving immediate adjustment. This rapid adjustment capability is crucial for maintaining the continuity of the production line and improving production efficiency. The rotating holes 401 on the movable end simplify the maintenance and replacement process of the paper guide rollers. When it is necessary to replace the paper guide rollers or perform regular maintenance, they can be quickly disassembled and installed, reducing downtime.
[0035] Through the above design, the adjustment accuracy, adaptability, stability, and maintenance convenience of the equipment are improved, thereby improving production efficiency and the quality of paper material processing.
[0036] Example 2, based on the above example, reference Figures 5-6A series of mounting points 50 are evenly arranged along the height direction of the rack 10, each mounting point 50 is provided with mounting holes, these mounting holes can be through holes or blind holes, their diameter and depth are designed according to the size of the connecting piece of the floating assembly 40, the inner wall of the mounting hole can be hardened or coated with wear-resistant material to improve durability, the floating assembly 40 can be connected with the mounting hole through bolts, pins or special quick connectors, the floating assembly 40 can be connected with different mounting points 50 according to needs to change its height position on the rack 10, for example, when processing paper material with large thickness, the floating assembly 40 can be connected with the mounting point 50 at a higher position to adjust the width of the second channel and avoid the paper material from entering the second channel smoothly.
[0037] Through the above design, the adjustment mechanism of the floating assembly 40 of the corrugator is more flexible and efficient, which can meet the processing needs of paper materials with different thicknesses, and improve the production efficiency and operation convenience.
[0038] It should be pointed out that after adjusting the height of the floating assembly 40, due to the gravity of the paper guide roller, the floating assembly 40 may be stretched, which may cause its elasticity to weaken and affect the flattening effect of the paper material.
[0039] In some embodiments, an elastic fitting design is adopted between the upper paper guide roller 301 and the floating assembly 40, in order to maintain the elastic effect of the floating assembly 40, the floating assembly 40 is equipped with a stop block 60, which is arranged on the side of the upper paper guide roller 301 close to the lower paper guide roller 302, the function of the stop block 60 is to provide additional support when the floating assembly 40 is stretched to prevent excessive stretching from causing a decrease in elasticity, the stop block 60 is slidably connected with the rack 10, this design allows the stop block 60 to slide up and down according to the stretching degree of the floating assembly 40, the stop block 60 is designed to slide against the lower side of the upper paper guide roller 301, this contact mode helps to provide stable support force when the paper material passes through, reducing the flattening effect caused by the stretching of the floating assembly 40.
[0040] In specific implementation, sliding rails matching the stop block 60 can be designed on the rack 10, these rails can be vertical, the stop block 60 can be connected with the rails through a connecting structure, this connecting structure can be a sliding block, a roller or a needle bearing to reduce friction and wear during sliding, the sliding of the stop block 60 along the rails can be adjusted by a manual knob, a lever or an automatic control system, this adjustment mechanism allows the operator to adjust the height of the stop block 60 according to the stretching of the floating assembly 40, in order to ensure that the stop block 60 can be stably maintained after being adjusted to the appropriate position, the rail system can be equipped with positioning and locking devices, these devices can be spring clips, ratchet locks or screw locks to prevent the stop block 60 from shifting when the paper material passes through.
[0041] Through the above design, the stop block 60 can effectively play its role in the floating assembly 40 of the corrugator, ensuring stable conveying and accurate leveling of the paper material under different working conditions.
[0042] In some embodiments, an assembly hole 70 is formed on the rack 10, and one end of the upper paper guide roller 301 is rotatably and movably clamped in the assembly hole 70. The assembly hole 70 can be formed by machining such as drilling, boring or milling, and the size accuracy and surface finish of the hole need to be ensured during machining. The assembly hole 70 can be designed as a groove structure with a certain depth, allowing the upper paper guide roller 301 to have limited floating in the vertical direction, and limiting the movement of the upper paper guide roller 301 in the horizontal direction, reducing the risk of paper material deviation.
[0043] Through the above design, the stable transmission of the paper material in the second channel is ensured, thereby improving the running efficiency of the corrugator and the quality of paper material processing.
[0044] In some embodiments, the two ends of the stop block 60 are arranged on both sides of the assembly hole 70, and one end of the upper paper guide roller 301 is rotatably stopped at the two ends of the stop block 60. The layout helps to maintain the vertical stability of the upper paper guide roller 301. Specifically, the stop block 60 can be designed with a groove or a flange to match the shape of the end of the upper paper guide roller 301, ensuring that the upper paper guide roller 301 can be stably stopped at the two ends of the stop block 60 when rotating. The stop block 60 can be made of wear-resistant material to reduce wear between the contact surfaces of the upper paper guide roller 301, prolonging the service life.
[0045] Through the above design, the stop block 60 can more effectively play its role in the floating assembly 40 of the corrugator, ensuring stable operation of the upper paper guide roller 301 and maintaining efficient paper leveling effect.
[0046] In other embodiments, the stop block 60 has an arc portion 601, and the center of the arc portion 601 is located on the upper side. The design of the arc portion 601 of the stop block 60 can be customized according to the curvature of the upper paper guide roller 301, ensuring that it can provide tighter fit and more uniform pressure distribution when in contact. At the same time, the arc portion 601 can also provide smoother contact, reducing friction and wear. The center located on the upper side helps to provide more uniform support force.
[0047] Through the above design, not only the adjustment ability and leveling effect of the corrugator are improved, but also the stability, maintenance convenience and production flexibility of the equipment are enhanced, further improving the production efficiency and the quality of paper material processing.
[0048] Working principle:
[0049] When the device is in use, the first paper guide roller set 20 is responsible for the preliminary guiding and conveying of the paper material, after the paper material enters the second channel, the pushing force generated by the contact of the paper material with the paper guide roller makes the paper guide roller rotate and float, realizing the self-adaptive adjustment of the channel width, the elastic deformation of the floating assembly 40 generates a reverse elastic force, ensuring that the paper material maintains close contact with the paper guide roller during the entire conveying process, the stop block 60 provides additional support to prevent the floating assembly 40 from being excessively stretched, maintaining the flattening effect.
