Description

Technical Field

[0001] The invention relates to the technical field of reel paper guiding and positioning, and in particular to a combined guide rail for reel paper tape and a working method. Background Art

[0002] As an important industrial material, paper reel plays a key role in many fields, especially in the application of cigarette and packaging equipment. With the increasing speed of equipment production, the display and feeding speed of paper reel has also been greatly accelerated, and the requirements for movement stability and position accuracy have become more stringent. The directional shaking and position deviation of paper reel during high-speed transportation will cause product appearance quality defects, and will also cause raw and auxiliary materials to break, block, scale and dirt on parts, and other faults and shutdowns, seriously damaging product quality, reducing machine efficiency, and increasing losses and waste.

[0003] Although the sophistication and operating speed of machinery and equipment have been continuously improved in the past few decades, most of the guide and positioning rails of reel paper tape still adopt the traditional fixed, single, single specification design (such as Figure 1 As shown). The disadvantage of the fixed type is that it cannot be adjusted to accommodate different reel tapes or different reel mounting frames, which in turn causes a centerline offset, and the offset of the tape centerline will cause a deviation in the gluing line and a difference in the appearance of the finished product. When it is within the quality requirements, only follow-up inspection can be strengthened. If the deviation is large, the machine must be stopped to adjust the position of the relevant process components. One adjustment often does not achieve satisfactory results, and multiple stops and repeated adjustments often occur. The fixed structure restricts the improvement of product appearance quality, reduces production efficiency, and increases material consumption. The disadvantage of the single type is that it is guided by only one inner and outer ring, with poor correction and controllability. The disadvantage of the single specification is that when the product process specifications change, the new reel tape can only be adapted by replacing the guide rail components or making mechanical adjustments.

[0004] Therefore, the existing technology has limitations in improving production efficiency and reducing material loss, which are specifically manifested as follows:

[0005] 1. Fixed guide rails cannot adapt to the deviation of the center line of the paper tape, resulting in product quality problems and frequent adjustment needs.

[0006] 2. The single guide rail has insufficient correction and controllability, and it is difficult to meet the precision requirements in high-speed production.

[0007] 3. Single-specification guide rails are difficult to adjust and lack flexibility when facing changes in product specifications. Summary of the invention

[0008] In view of the shortcomings of the prior art, the purpose of the embodiments of the present invention is to provide a combined guide rail and working method for a reel paper tape, which can achieve adjustable position, combined stabilization, quick specification change, fine adjustment, wide amplitude modulation, and flexible and variable paper routing.

[0042] It should be noted that the following detailed descriptions are illustrative and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those of ordinary skill in the art to which the present invention belongs. In addition, it should also be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0043] In view of the traditional fixed, single, single-specification design of the reel paper tape guiding and positioning rails, this embodiment innovatively proposes and designs a combined guide rail and working method with adjustable position, combined stabilization, quick specification change, fine fine-tuning, wide amplitude, and variable paper routing to improve the running stability of the reel paper tape and the flexibility of process adjustment.

[0044] like Figure 2 As shown, this embodiment relates to a combined guide rail for a reel paper tape, which mainly includes a guide rail assembly, a guide rail support assembly and a roller support shaft assembly. The guide rail assembly is composed of an upper guide rail assembly, a middle guide rail assembly and a lower guide rail assembly, and these three assemblies are arranged in sequence on the same plane. The middle guide rail assembly can be installed on the guide rail support assembly and can be rotated and adjusted along its axis, and all guide rail assemblies can be synchronously extended and retracted along the axis direction of the guide rail support assembly.

[0045] The combined guide rail increases the number of guide rails, and the upper, middle and lower guide rail components 2, 1 and 3 improve the performance of suppressing the swing of the paper tape in the direction of movement; the combined guide rail can be turned half a circle on the guide rail support component 6 as a whole, and quickly converted to another commonly used width specification; the combined guide rail can adjust the process center position inward and outward along the axis of the guide rail support component 6 to adjust the reel paper tape 10 to align with the equipment operation process center line, and the position adjustment range is 20mm. The specification width of the combined guide rail can be adjusted synchronously by adjusting the upper and lower guide rail components 2 and 3. It can be fine-tuned to adapt to the differences in the width of reels of paper tapes 10 of the same specification, and can also be greatly adjusted to adapt to the differences in the width of reels of paper tapes 10 of various specifications. By adjusting the fixed angles of the upper and lower guide rail components 2 and 3 and the connecting clamp 7 and other components, the change of the reel paper tape winding route can be realized to achieve more stable process control.

[0046] like Figure 3 , Figure 4 As shown, the guide rail support assembly is mainly composed of a guide rail support, a positioning ring and a spring. The guide rail support is a stepped shaft with a large diameter shaft and a small diameter shaft, and the small diameter shaft is the guide rail sliding working surface. The middle guide rail assembly includes a hollow tube-shaped support rail, and the positioning ring is clamped with the support rail and sleeved on the small diameter shaft of the guide rail support. The two ends of the spring are respectively abutted on the end faces of the large diameter shaft and the positioning ring. The elastic force of the spring ensures the stability and reliability of the support rail during use, while reducing the impact of vibration on the guide rail system and improving the smoothness of paper tape transmission.

[0047] The end face of the large diameter shaft of the guide rail support is matched with the connecting clamp, and the mounting surface is provided with fastening screw holes, and the connecting clamp and the guide rail support are fastened by bolts to ensure the fixity and stability of the guide rail support assembly. At the same time, symmetrical grooves are provided on the circumferential surface of the large diameter shaft.

[0048] The end face of the minor diameter shaft of the guide rail support is provided with an axial transmission threaded hole for installing the transmission stud. The fine threaded rod of the transmission stud can achieve fine adjustment, which is convenient for fine adjustment during use. The knurled cylindrical end design of the transmission stud helps to increase the friction during operation, which facilitates the user to get a better sense of control during the adjustment process, ensuring that the adjustment can be completed quickly and effectively in actual operation.

[0049] An upper groove and a lower groove are arranged on the end surface of the positioning ring facing the support rail, and an upper convex block and a lower convex block are arranged on the end surface of the support rail facing the positioning ring. The upper convex block and the lower convex block are respectively inserted into the upper groove and the lower groove. Through this structural design, a stable connection relationship is formed between the positioning ring and the support rail, which can effectively prevent relative displacement and improve the overall operation efficiency.

[0050] Combination Figure 3 , Figure 4 For detailed explanation:

[0051] The guide rail support 6.1 is the main part of the guide rail support assembly 6, and supports and guides the upper, middle and lower guide rail assemblies 2, 1 and 3. By tightening the screw holes 6.1.2, the mounting surface 6.1.1 is fitted with the working surface of the connecting splint 7 to ensure positioning and stability. The symmetrical grooves 6.1.3 are used to apply circumferential torque through a wrench during installation, which is convenient for tightening and positioning. The axial transmission threaded hole 6.1.4 is a fine thread, which is used to screw in and out to adjust the working position of the upper, middle and lower guide rail assemblies 1, 2 and 3. The guide rail sliding working surface 6.1.5 is the sliding and guiding working surface of the middle guide rail assembly 1. The screw holes 6.1.6 are used to install tightening and guiding screws.

[0052] The guide rail support 6.1 is installed on the connecting clamp 7 by means of bolts 6.4. The spring 6.3, the positioning ring 6.2 and the support rail 1.1 are sequentially mounted on the guide rail support 6.1; the transmission stud 6.5 is installed in the axial transmission threaded hole 6.1.4. The inner circular hole of the positioning ring 6.2, the inner circular hole of the support rail 1.1 and the guide rail sliding working surface 6.1.5 are clearance-matched and can slide relatively under the action of external force. Under the pressure of the spring 6.3 and the limiting action of the transmission stud 6.5, the support rail 1.1 is axially positioned on the guide rail support 6.1. The upper groove 6.2.3 and the lower groove 6.2.4 on the positioning ring 6.2 can engage and disengage with the upper protrusion 1.1.1 and the lower protrusion 1.1.2 on the support rail 1.1; when engaged, the support rail 1.1 is limited in the circumferential direction by the positioning ring 6.2. The knurled stud 6.5.2 is convenient for turning the fine thread rod 6.5.1 by hand. When turning inward, it resists the pressure of the spring 6.3, so that the support rail 1.1 moves inward under the guidance of the guide rail support 6.1; when turning outward, it moves outward under the pressure of the spring 6.3, thereby changing the working position of the middle guide rail assembly 1.

[0053] like Figure 5 , Figure 6 As shown, the guide rail support assembly also includes a sleeve, and the two ends of the sleeve are respectively sleeved on the large diameter shaft and the positioning ring of the guide rail support. By providing the guide fastening screw hole and the guide long hole, the installation of the guide fastening screw further enhances the stability of the guide rail support assembly. At the same time, the design of the left screw hole and the right screw hole of the positioning ring can provide additional adjustment space, thereby improving its adaptability and flexibility.

[0054] The middle rail assembly includes an inner rail and an outer rail, which are respectively sleeved on both ends of the support rail and fixed to the support rail through positioning screw holes. The opposite surfaces of the inner rail and the outer rail are designed as step surfaces. Different surface designs can meet the requirements of different specifications of reel tapes, ensuring that the combined rail can adapt to various work needs and improve its versatility and scope of application.

[0055] Combination Figure 5 , Figure 6For detailed explanation:

[0056] The first fixing screw 6.8 and the second fixing screw 6.9 pass through the first circular hole 6.6.2 and the second circular hole 6.6.3 respectively and are fastened to the left screw hole 6.2.1 and the right screw hole 6.2.2, so as to fix the sleeve 6.6 on the positioning ring 6.2. During assembly, the center line of the guide slot 6.6.1 is axially aligned with the center point of the guide fastening screw hole 6.1.6 on the guide rail support 6.1. When the guide fastening screw 6.7 is tightened, it is used to lock the axial and circumferential position of the middle guide rail assembly. When it is loosened, it is used to limit the circumferential position of the middle guide rail assembly such as the positioning ring 6.2 and the support rail 1.1, and plays the role of guiding, limiting and preventing the middle guide rail assembly such as the support rail 1.1, the inner side rail 1.2, and the outer side rail 1.3 from falling out when the middle guide rail assembly moves axially. In this embodiment, the design length of the guide slot 6.6.1 is 20 mm, that is, the design value of the axial adjustment amplitude of the middle guide rail assembly through the transmission stud 6.5 is 20 mm. The inner side rail 1.2 and the outer side rail 1.3 are installed on the support rail 1.1. For a relatively precise clearance fit, they can slide on the support rail surface and are axially and circumferentially fixed on the outer cylindrical surface of the support rail 1.1 by the first tightening screw 1.4 and the second tightening screw 1.5 respectively.

[0057] The left screw hole 6.2.1 and the right screw hole 6.2.2 on the positioning ring 6.2 are arranged symmetrically, and the sleeve 6.6 is fastened to the positioning ring 6.2 by two symmetrical screws 6.8 / 6.9, ensuring that the positioning ring 6.2 is balanced in the circumferential direction when subjected to the tensile force transmitted axially by the sleeve 6.6, without skewing, to prevent it from getting stuck. Loosen the guide fastening screw 6.7, hold the sleeve 6.6 to overcome the pressure of the spring 6.3, drive the positioning ring 6.2 to move axially, and disengage from the 1.1 support rail. The support rail 1.1 and the related components of the middle guide rail combined with it can rotate and slide on the guide rail sliding working surface 6.1.5. After rotating 180°, the upper and lower grooves 6.2.3 / 6.2.4 are engaged with the upper and lower protrusions in a transposition manner to achieve the change of the commonly used specification width. The outer rail 1.3 is provided with positioning screw holes 1.3.3 for tightening and positioning the support rail 1.1 in the axial and circumferential directions. The wide working surface 1.3.2 and the narrow working surface 1.3.1 are used for conversion of commonly used width specifications. The inner rail 1.2 has the same structure as the outer rail 1.3 and is symmetrically assembled. The inner and outer rails 1.2 / 1.3 can be increased to three to four commonly used width specification working surfaces, and the number of grooves on the positioning ring 6.2 and the number of protrusions on the support rail 1.1 are also increased to three to four accordingly.

[0058] like Figure 7As shown, in this embodiment, the structure of the upper guide rail assembly is the same as that of the lower guide rail assembly, and the design of the upper rail includes a compression spring and a fine-threaded through hole, which can adjust the spacing of the guide rail assembly to adapt to reels of different specifications. This design makes the alignment of the reel more accurate and improves the operating efficiency, while also ensuring the flexibility and adjustability of the equipment to adapt to the changing needs of the production line.

[0059] The upper support rail 2.1 of the upper guide rail assembly is designed with symmetrical countersunk holes at both ends, and a fine-threaded through hole 2.1.1 is designed in the center. The upper outer side rail 2.3 is provided with a narrow specification surface 2.3.1 and a wide specification surface 2.3.2, which are combined with the specification surfaces corresponding to the upper inner side rail 2.2 for conversion of commonly used width specifications. The upper inner side rail 2.2 and the upper outer side rail 2.3 can have the same structure and be assembled symmetrically. The upper inner and outer side rails 2.2 / 2.3 can be increased to three to four working surfaces of commonly used width specifications. The inner holes of the upper inner and outer side rails 2.2 / 2.3 are clearance-fitted with the outer cylindrical surface of the upper support rail 2.1, and are supported and guided, and can slide axially relative to each other. The round rods 2.8.2 / 2.9.2 also support and guide the upper inner and outer side rails 2.2 / 2.3. The fine pitch thread 2.8.1 / 2.9.1 is screwed into the fine pitch thread through hole 2.1.1, and the adjusting bolt 2.8 / 2.9 is rotated to cooperate with the compression spring 2.6 / 2.7 to adjust and position the upper inner and outer side rails 2.2 / 2.3 on the upper support rail 2.1 in the axial direction. The tightening screws 2.4 / 2.5 are respectively installed on the tightening screw holes 2.2.3 / 2.3.3 to tighten the relative positions of the upper inner and outer side rails 2.2 / 2.3 and the support rail 2.1 in the axial and circumferential directions.

[0060] like Figure 8 , Fig. 9 As shown, the combined guide rail includes an outer connecting plate and an inner connecting plate, and the guide rail assembly is connected through three circular holes. This split structure of the outer connecting plate and the inner connecting plate not only provides better stability, but the design of the connecting plate helps to simplify the assembly process, while enhancing the overall load-bearing capacity and effectively improving the service life of the guide rail assembly.

[0061] The outer connecting plate 4 and the inner connecting plate 5 connect and fasten the middle guide rail assembly 1, the upper guide rail assembly 2, and the lower guide rail assembly 3 into a combined guide rail assembly. There are three circular holes 4.2 on the outer connecting plate 4, which are used to insert and install the upper outer side rail 2.3, the middle side rail 1.3, and the lower outer side rail 3.3 respectively; there are two notches 4.5 between the three circular holes 4.2; four groups of through holes 4.3 and threaded holes 4.4, four bolts 4.1 are inserted and installed respectively; by tightening the bolts 4.1, the outer connecting plate 4 can fix the upper, middle, and lower outer side rails 2.3 / 1.3 / 3.3 installed in combination with it as a linkage assembly. The structural dimensions of the inner connecting plate 5 are the same as those of the outer connecting plate 4. By tightening the four bolts 5.1, the outer connecting plate 5 can fix the upper, middle, and lower inner side rails 2.2 / 1.2 / 3.2 installed in combination with it as a linkage assembly.

[0062] When the first tightening screws 1.4 / 2.4 / 3.4 are tightened and positioned, the three second tightening screws 1.5 / 2.5 / 3.5 on the other side are fully loosened, and the adjusting bolts 2.9 / 3.9 are turned at the same angle at the same time, so that the upper outer side rail 2.3 slides on the outer surface of the upper support rail 2.1, and the lower outer side rail 3.3 slides on the lower support rail 3.1, respectively, to drive the outer connecting plate 4 to move; the middle side rail 1.3 moves synchronously with the upper outer side rail 2.3 and the lower outer side rail 3.3 under the drive of the outer connecting plate 4, so that the outer side rails 2.3 / 3.3 / 1.3 move as a whole, and the width specifications are fine-tuned. Similar steps, when the second tightening screws 1.5 / 2.5 / 3.5 are tightened and positioned, the three first tightening screws 1.4 / 2.4 / 3.4 on the other side are fully loosened, and the adjusting bolts 2.8 / 3.8 are turned at the same angle at the same time, so that the upper inner side rail 2.2 slides on the outer surface of the upper support rail 2.1, and the lower inner side rail 3.2 slides on the lower support rail 3.1, respectively, to drive the inner connecting plate 5 to move; the middle side rail 1.2 moves synchronously with the upper inner side rail 2.2 and the lower inner side rail 3.2 under the drive of the inner connecting plate 5, so that the inner side rails 2.2 / 3.2 / 1.2 move as a whole, and the width specifications are fine-tuned. The inner and outer side rail components move toward the center line to close to the stop point, and the width specifications of the combined guide rails are greatly reduced. The combined guide rail width fine-tuning is used for a wider range of reel paper tapes of different widths, and is suitable for material changes of different products.

[0063] The working method of the combined guide rail for reel tape described above:

[0064] By turning the three rail assemblies half a turn on the rail support assembly, the conversion of different width specifications can be achieved. This method also allows the process center position to be adjusted inside and outside to adapt to the operation requirements of different paper tape alignment equipment. In addition, the synchronous adjustment of the upper and lower rail assemblies can flexibly adapt to the differences in reels of the same specification, ensuring the efficient operation of the equipment under various working conditions, and improving the flexibility and adaptability of production. By adjusting the fixed angles of the upper and lower rail assemblies and connecting splints and other components, the paper winding route of the reel can be changed to achieve more stable process control.

[0065] The present invention is flexible in structure, specification and process application and has various forms. For example, by loosening the four clamping screws 5.1 on the inner connecting plate 5 and the four clamping screws 4.1 on the outer connecting plate, the upper guide rail assembly 2 and the lower guide rail assembly 3 are kept stationary, and the middle guide rail assembly 1 is rotated 180 degrees as a whole, the winding process route of the reel paper tape 10 can be changed, such as Fig.10 As shown, the interference and control of the reel paper tape can be relatively enhanced.

[0066] The combined guide rail and working method increase the flexibility and versatility of the functions, effectively improve the comprehensive operation performance of the machine equipment, enhance the adaptability to the specifications and materials of raw and auxiliary materials, and improve the quality of the lean process. It is beneficial to reduce the frequency of appearance quality defects of finished products, improve production efficiency, reduce waste material consumption, and reduce the labor intensity of employees. In order to increase the operating speed, the number of machines and equipment that continuously input raw and auxiliary materials at high speed in the form of reel paper tape is increasing. The relevant design of the present invention can be applied to many advanced and modern machines and equipment, and has a relatively wide promotion value.

[0067] Although the above describes the specific implementation mode of the present invention in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art on the basis of the technical solution of the present invention without creative work are still within the scope of protection of the present invention.
