Description

Technical Field

[0001] This invention relates to the field of roller manufacturing technology, and more specifically, to a roller manufacturing device. Background Technology

[0002] In the field of roller processing, especially in the production of precision rollers such as anilox rollers and printing rollers, the feeding accuracy directly determines the geometric dimensional accuracy and surface finish quality of the roller. Currently, roller manufacturing equipment in the industry generally suffers from design flaws in its feeding mechanism: traditional feeding devices mostly adopt a single-section telescopic arm or hydraulic push rod structure, which limits the adjustment of the telescopic stroke, and the workpiece conveying and telescopic drive need to be controlled independently, resulting in poor synchronization, large feeding errors, and problems such as cutting size deviations or uneven polishing.

[0003] Among existing patented technologies, such as the "Integrated Turning and Grinding Machine for Roller Production" with application number CN202420370941.3, this equipment integrates turning and grinding of the roller body by incorporating a grinding mechanism and positioning components in the machine box mechanism. It completes the roller positioning by driving the extrusion plate to rise and fall through the threaded rod, which improves the processing stability to a certain extent.

[0004] While the integrated machine from Qingdao Tianlu Zhengong achieves the integration of turning and grinding, the feeding mechanism does not achieve synchronous drive for rotation and extension. In actual processing, the roller body needs to complete axial feed and circumferential rotation simultaneously to ensure polishing accuracy. Existing equipment mostly uses independent drive modules to control the two movements separately, resulting in action delays. This is especially prone to radial runout when processing rollers with a large length-to-diameter ratio, affecting surface finish. Summary of the Invention

[0005] Based on this, in order to solve the problems of large space occupation and large feeding error of traditional equipment, the present invention provides a roller making device, the specific technical solution of which is as follows: A roller making device, comprising A feeding device includes a support and a telescopic structure. The support has a housing, and the telescopic structure is mounted on the support. The telescopic structure includes multiple sleeves that are coaxially nested and can extend and retract relative to each other axially. Adjacent sleeves are slidably fitted together. The outermost sleeve is inserted into the housing and reciprocates along the length of the housing. The feeding device also includes a drive structure and a transmission structure. The transmission structure has a channel for the workpiece to pass through and is located inside the sleeves. The drive structure is connected to the transmission structure and drives the transmission structure to rotate. The transmission structure drives the multiple sleeves to extend and retract relative to each other axially. A clamping device is provided on one end of the sleeve, and the clamping device is used to clamp the workpiece passing through the channel; A cutting device for cutting a workpiece; A polishing device is used to polish the outer surface of a workpiece, and a feeding device is used to drive the workpiece to pass sequentially through the cutting device and the polishing device.

[0006] The aforementioned roller-making equipment features multiple coaxial nested sleeves with an integrated transmission structure. Compared to traditional linkage-type telescopic designs, this completely eliminates transmission gaps between multiple components, significantly reduces feeding errors, and improves the dimensional accuracy and coaxiality of roller processing, making it suitable for precision roller production needs. The sleeve telescopic stroke is flexibly adjustable (up to 3-5 times the length of a single section), and the transmission structure can adapt to roller processing of different lengths without replacing core components, greatly improving the equipment's versatility and applicability. The feeding device is rigidly connected to the workpiece through a clamping device, realizing a continuous "feeding-cutting-polishing" process, eliminating the intermediate transfer links of traditional equipment, shortening the processing cycle, and improving batch production efficiency. The integrated design simplifies the equipment structure, significantly reducing space occupation compared to traditional discrete equipment, lowering workshop layout costs, and improving site utilization. The simultaneous "axial telescopic conveying" and "circumferential rotation" actions allow the equipment to adapt to complex roller processing scenarios: in the polishing process, the roller rotation ensures uniform force on the outer surface, resulting in a finer polished texture.

[0022] In this invention, the terms "first" and "second" do not represent a specific quantity or order, but are merely used to distinguish names.

[0023] like Figures 1-4As shown, a roller-making device according to one embodiment of the present invention includes a feeding device 1, a clamping device 4, a cutting device 5, and a polishing device 6; the feeding device 1 includes a bracket 11 and a telescopic structure 12, the bracket is provided with a housing 24, the telescopic structure 12 is disposed on the bracket 11, the telescopic structure 12 includes multiple sleeves 2 that are coaxially nested in sequence and can be axially extended and retracted, and adjacent sleeves 2 form a sliding fit, wherein the outermost sleeve 2 is inserted into the housing 24 and reciprocates along the length direction of the housing 24; the feeding device 1 also includes a driving structure 13 and a transmission structure 14, the transmission structure 13 and the transmission structure 14 are used to drive the rollers. The moving structure 14 has a channel 3 for the workpiece to pass through. The transmission structure 14 is located inside the sleeve 2. The driving structure 13 is connected to the transmission structure 14. The driving structure 13 cooperates with multiple sections of the sleeve 2 to drive the transmission structure 14 to rotate and simultaneously extend and retract. The clamping device 4 is located on one end of the transmission structure 14 and is used to clamp the workpiece passing through the channel 3. The cutting device 5 is used to cut the workpiece. The polishing device 6 is used to polish the outer surface of the workpiece. The feeding device 1 is used to drive the workpiece to pass through the cutting device 5 and the polishing device 6 in sequence.

[0024] The aforementioned roller-making equipment, with its multi-section coaxial nested sleeves 2 and built-in transmission structure 14, completely eliminates transmission gaps between multiple components compared to the traditional linkage-type telescopic design, significantly reducing feeding errors and improving the dimensional accuracy and coaxiality of roller processing, thus meeting the production needs of precision rollers. The telescopic stroke of the sleeves 2 can be flexibly adjusted (up to 3-5 times the length of a single section), and the transmission structure 14 can adapt to the processing of rollers of different lengths without replacing core components, greatly improving the equipment's versatility and applicability. The feeding device 1 is rigidly connected to the workpiece through the clamping device 4, realizing a continuous process of "feeding-cutting-polishing," eliminating the intermediate transfer links of traditional equipment, shortening the processing cycle, and improving batch production efficiency. The integrated design simplifies the equipment structure, significantly reducing the space occupied compared to traditional discrete equipment, lowering workshop layout costs, and improving site utilization. The simultaneous "axial telescopic conveying" and "circumferential rotation" actions allow the equipment to adapt to composite processing scenarios of rollers: in the polishing process, the rotation of the rollers makes the outer surface uniformly stressed, resulting in a finer polishing texture. This roller-making equipment solves the problems of large space occupation and large feeding error of traditional equipment.

[0025] like Figures 1-8As shown, in one embodiment, the sleeve 2 is provided with a sliding groove 7 and a guide block 8. The guide block 8 of the sleeve 2 is inserted into the sliding groove 7 of an adjacent sleeve 2, and the guide block 8 of the sleeve 2 is slidably connected to the sliding groove 7 of the adjacent sleeve 2. The transmission structure 14 includes a threaded component 141 and a moving component 142. The channel 3 is provided in the threaded component 141. One end of the threaded component 141 is inserted into the bracket 11 and rotatably connected to the bracket 11. The moving component 142 is sleeved on the threaded component 141 and is rotatably connected to the bracket 11. The threaded component 141 is threadedly connected; the moving assembly 142 includes a plurality of sequentially coaxially nested moving structures 9, adjacent moving structures 9 are threadedly connected, and one moving structure 9 is connected to one sleeve 2; each moving structure 9 includes a threaded cylinder 91 and a moving block 92, one moving block 92 is disposed on the threaded component 141 and threadedly connected to the threaded component 141; the moving block 92 includes a disc portion 922 and a connecting portion 921 disposed on the disc portion 922, the disc portion 922 is connected to the sleeve 2; the connecting portion 921 is threadedly connected to the sleeve 2. The connecting part 921 is provided with a first slide rail 10 with an arc-shaped outer contour; the threaded cylinder 91 is sleeved on the connecting part 921, and the threaded cylinder 91 is provided with a first sliding block 21; the first sliding block 21 on the threaded cylinder 91 of one of the moving structures 9 is inserted into the first slide rail 10 on the adjacent moving block 92 of the same moving structure 9; a second sliding block 23 is provided inside the threaded cylinder 91, and the threaded cylinder 91 is provided with a second slide rail 22; the second sliding block 23 on the threaded cylinder 91 of one of the moving structures 9 is inserted into the first slide rail 10 on the adjacent moving block 92 of another moving structure 921. On the second slide 22 of the threaded cylinder 91 of the movable structure 9, a second sliding block 23 on one of the threaded cylinders 91 of the movable structure 9 is slidably connected to the second slide 22 of the adjacent threaded cylinder 91 of the movable structure 9; the threaded component 141 is also provided with a second slide 22, and a second sliding block 23 on one of the threaded cylinders 91 of the movable structure 9 is inserted into the second slide 22 of the threaded component 141, and the second sliding block 23 on the threaded cylinder 91 of the movable structure 9 is slidably connected to the second slide 22 of the threaded component 141.Thus, the sleeve 2 slides with the groove 7 of the adjacent sleeve 2 through the guide block 8, forming a precise axial guide, avoiding radial offset when the sleeve 2 extends or retracts, further ensuring the coaxiality of the feeding process and improving transmission stability; the transmission structure 14 adopts a "threaded part 141 + multiple nested moving structures 9" design, the threaded part 141 and the moving component 142 are threadedly connected and slide with the sliding track between the moving structures 9, realizing the synchronous transmission of extension and rotation actions, with high transmission efficiency and no jamming; in the moving structure 9, the threaded cylinder 91 and the moving block 92 are in multi-layer sliding cooperation through the first slide track 10 and the second slide track 22. The multi-stage nested transmission not only extends the overall telescopic stroke but also ensures the precision of each stage of movement, further optimizing the adaptability of rollers of different lengths. The direct connection between the disc part 922 and the sleeve 2, and the arc-shaped first slide 10 design of the connecting part 921, reduce motion interference, lower transmission resistance, and improve the smoothness of equipment operation and service life. The combination structure of the multi-layer first slide 10 and the threaded connection further reduces the transmission gap, thereby improving the feeding accuracy and the coaxiality of roller processing, adapting to higher precision roller production scenarios. At the same time, the sleeve 2 can also protect the threaded cylinder 91.

[0026] like Figure 2 As shown, in one embodiment, the drive structure 13 includes a first gear 131, a second gear 132, a third gear 133, and a drive motor 134. The drive motor 134 is mounted on the bracket 11, and its output end is connected to the third gear 133. The third gear 133, the second gear 132, and the first gear 131 mesh sequentially. The second gear 132 is mounted on the bracket 11 and rotatably connected to it. The first gear 131 is sleeved on the threaded component 141. Thus, by employing a multi-stage meshing transmission structure of "drive motor 134 + third gear 133 + second gear 132 + first gear 131," power transmission is smooth, torque output is uniform, impact loads caused by direct drive are avoided, the threaded component 141 and sleeve 2 structure are protected, and the stability of equipment operation is improved. The reduction ratio of the gear transmission can be flexibly adjusted through gear parameters to adapt to the feeding speed requirements of different specifications of rollers, meeting diverse processing scenarios.

[0027] like Figure 2As shown, in one embodiment, the clamping device 4 includes a mounting base 41 and a plurality of clamping components 42. The mounting base 41 is disposed on the innermost threaded cylinder 91. The mounting base 41 has an opening 43 communicating with the channel 3. The plurality of clamping components 42 are arranged circumferentially around the opening 43 and are disposed on the mounting base 41. The plurality of clamping components 42 are used to clamp the workpiece. Thus, multiple clamping components 42 are evenly distributed around the opening 43, which can apply uniform clamping force from the circumference of the workpiece, avoiding workpiece deformation caused by local stress concentration during clamping, while ensuring the coaxiality of the workpiece and the channel 3, and preventing misalignment during feeding and processing; the mounting base 41 is directly connected to the threaded cylinder 91, ensuring that the clamping device 4 and the transmission structure 14 move synchronously, so that the clamping state of the workpiece is stable during extension, contraction and rotation, and improving processing consistency; the clamping components 42 are connected to the channel 3 in conjunction with the opening 43, ensuring that the workpiece can be smoothly inserted, and the opening degree of the clamping components 42 can be adjusted to adapt to workpieces of different diameters, improving clamping versatility; the structure is compact, highly integrated with the transmission structure 14, does not occupy additional equipment space, and the clamping action is highly coordinated with the feeding and processing processes, without affecting the overall processing efficiency.

[0028] like Figure 9 As shown, in one embodiment, the cutting device 5 includes a frame 51, a transport chain 52, a first cylinder 53, a clamping block 54, a moving drive structure 55, and two sets of cutting structures 56. The transport chain 52 is mounted on the frame 51, and the first cylinder 53 is mounted on the frame 51 and connected to the clamping block 54. The first cylinder 53 is used to drive the clamping block 54 to move up and down. The moving drive structure 55 is mounted on the frame 51, and the two sets of cutting structures 56 are both mounted on the moving drive structure 55. The moving drive structure 55 is used to drive the cutting structures 56 to move towards each other and backwards. Thus, the transport chain 52 works in conjunction with the feeding device 1 to achieve auxiliary conveying and positioning of the workpiece, ensuring the continuity of the cutting process and adapting to the needs of mass production; the first cylinder 53 drives the clamping block 54 to rise and fall, which can perform secondary auxiliary clamping and positioning of the workpiece, avoiding workpiece shaking during the cutting process and significantly improving the flatness of the cutting surface and cutting accuracy; the moving drive structure 55 drives the two sets of cutting structures 56 to move in opposite directions / backwards, which can flexibly adjust the cutting spacing to adapt to the cutting needs of rollers with different diameters and improve the versatility of the cutting device 5; the two sets of cutting structures 56 work together to simultaneously cut both sides or the outer periphery of the roller, improving cutting efficiency and avoiding workpiece deformation caused by excessive force in a single cut.

[0029] like Figures 10-12As shown, in one embodiment, the moving drive structure 55 includes a left-hand and right-hand lead screw 551 and a first motor 552; the first motor 552 is mounted on the frame 51, and the output end of the first motor 552 is connected to one end of the left-hand and right-hand lead screw 551, and the first motor 552 is used to drive the left-hand and right-hand lead screw 551 to rotate; one cutting structure 56 is mounted on one end of the left-hand and right-hand lead screw 551 and threadedly connected to the left-hand and right-hand lead screw 551, and another cutting structure 56 is mounted on the other end of the left-hand and right-hand lead screw 551 and threadedly connected to the left-hand and right-hand lead screw 551. Thus, the left and right spiral lead screws 551 are threadedly connected to the two sets of cutting structures 56, and driven by the first motor 552, the two sets of cutting structures 56 move synchronously in opposite directions, ensuring uniform cutting volume on both sides during the cutting process and improving the symmetry and accuracy of the cutting surface. The first motor 552 directly drives the left and right spiral lead screws 551, resulting in a short transmission path, reducing the gap and energy loss of intermediate transmission components, improving the motion response speed and position control accuracy of the cutting structure 56, and meeting the requirements of high-precision cutting. The threaded transmission method has strong stability, avoiding vibration or deviation during the movement of the cutting structure 56, ensuring the stability of the cutting process, and further optimizing the quality of the cutting surface.

[0030] In one embodiment, a flexible auxiliary support block is provided within the channel 3. Thus, when the workpiece is long, the flexible auxiliary support block effectively reduces the likelihood of deformation. Furthermore, when processing begins and the workpiece rotates around its own axis, each part of the circumference alternately lies on the "drooping side." The point of application of gravity is no longer fixed in a certain direction but is evenly distributed along the circumference. That is, the originally static "unilateral deflection deformation" is transformed into dynamic, uniform, minute deformation, effectively reducing the occurrence of deformation.

[0031] Working principle: 1. Feeding and clamping positioning The operator inserts the workpiece through the transmission structure 14 channel 3 of the feeding device 1 until the front end of the workpiece reaches the opening 43 of the mounting base 41 of the clamping device 4. The multiple sets of circumferential clamping components 42 of the clamping device 4 operate synchronously to achieve multi-point uniform clamping from the circumference of the workpiece. The rigid connection ensures that the axis of the workpiece is coaxial with the extension and retraction direction of the sleeve 2, avoiding clamping deformation or eccentricity, and laying the foundation for subsequent processing accuracy. 2. Precise material feeding during polishing stroke Drive structure 13 starts: Drive motor 134 drives threaded part 141 to rotate smoothly through multi-stage meshing transmission of third gear 133, second gear 132 and first gear 131 (gear transmission ensures uniform torque and avoids impact load). Sleeve 2 telescopic control: When the threaded part 141 rotates, the moving block 92 of the moving component 142 sleeved on it drives the axial telescopic movement of multiple sleeve sections 2 through threaded transmission—adjacent sleeve sections 2 achieve precise guidance through the sliding cooperation of the sliding groove 7 and the guide block 8 (e.g. Figure 6 (As shown); Under the push of the moving block 92, the threaded cylinder 91 performs synchronous axial extension and retraction. Because (the threaded cylinder 91 is provided with a second sliding block 23, and the threaded cylinder 91 is provided with a second slide rail 22, the second sliding block 23 on the threaded cylinder of one of the moving structures 9 is inserted into the second slide rail 22 on the threaded cylinder 91 of the adjacent moving structure 9, and the second sliding block 23 on the threaded cylinder of one of the moving structures 9 is slidably connected to the second slide rail 22 on the threaded cylinder 91 of the adjacent moving structure 9; the threaded component 141 is also provided with a second slide rail 22, and the second sliding block 23 on the threaded cylinder 91 of one of the moving structures 9 is inserted into the threaded component 141); On the second slide 22 of 141, the second sliding block 23 on the threaded cylinder 91 of the moving structure 9 is slidably connected to the second slide 22 of the threaded component 141, so that multiple threaded cylinders 91 can rotate synchronously with the threaded component 141 and perform axial extension and retraction movements. At the same time, the sliding block 21 of the moving structure 9 cooperates with the arc-shaped first slide 10 to achieve slide constraint. Then, when the driving structure 13 drives the threaded component 141 to rotate, multiple threaded cylinders 91 can rotate synchronously with the threaded component 141 and perform axial extension and retraction movements. That is, the threaded motion is converted into a smooth extension and retraction force through "threaded engagement → slide constraint → directional transmission of force", and ensures that the sleeve 2 extends and retracts without deviation or jamming. Length adaptation and feeding: According to the preset roller length requirements, the sleeve 2 extends and retracts to the corresponding stroke (up to 3-5 times the length of a single section), driving the clamped workpiece to move towards the polishing device 6 until the entire length of the workpiece to be polished is completely entered into the processing area of ​​the polishing device 6. The feeding process eliminates transmission gaps and ensures that the feeding error is minimized. 3. Polishing process Polishing device 6 is started to polish the outer surface of the workpiece that has been fed into place; The feeding device 1 maintains the clamping state and can finely adjust the extension and retraction speed of the sleeve 2 according to the polishing requirements (adjusted by the gear reduction ratio) to ensure that the outer surface of the workpiece is polished evenly and smoothly, and the workpiece does not loosen or shift throughout the process (relying on the rigid connection of the clamping device 4 and the stable support of the sleeve 2). 4. Secondary feeding and positioning before cutting After polishing is completed, the feeding device 1 transports the workpiece to the cutting station. The feeding device 1 stops working, and at this time the first cylinder 53 drives the clamping block 54 to descend, pre-fixing the workpiece to avoid vibration during the cutting process.

[0032] 5. Precision cutting operation The moving drive structure 55 of the cutting device 5 is started: the first motor 552 drives the left and right rotating screw 551 to rotate, which drives the two sets of cutting structures 56 to move synchronously towards each other along the screw (the cutting gap is preset according to the workpiece diameter). Two sets of cutting structures 56 simultaneously cut the workpiece. The left and right rotating lead screws 551 ensure that the two sets of cutting structures 56 move symmetrically, improve the flatness of the cut, and reduce burrs and dimensional deviations. After the cutting is completed, the first cylinder 53 drives the clamping block 54 to rise and take out the processed workpiece. At the same time, the multiple clamping components 42 of the clamping device release the workpiece, and the workpiece falls on the conveyor chain 52 to avoid the workpiece falling to the ground, so that the subsequent feeding device 1 can reset and re-clamp the workpiece. Then the feeding device 1 resets and prepares for the next round of processing. 6. Cyclic Operation Repeat the above process of "feeding, clamping, polishing, cutting, cutting, and unloading" to achieve continuous processing of batch roller parts.
