Abstract

This invention provides a grinding device for the outer diameter of textile rubber rollers, belonging to the field of rubber roller processing technology. It includes a rubber roller grinding machine, whose inner wall is slidably connected to a feed mechanism via a linear guide rail. A first sliding frame is fixedly connected to the top of the feed mechanism. This invention, by setting a support mechanism, effectively solves the processing defects caused by uneven elastic deformation of the rubber roller, improving processing quality and work efficiency. The support mechanism, by setting a first extrusion roller, a second extrusion roller, and a third extrusion roller, simultaneously applies extrusion force from the bottom, opposite, and top of the grinding point, respectively, ensuring that the extrusion force is consistent with the grinding force.

Description

Technical Field

[0001] This invention relates to the field of rubber roller processing technology, and in particular to a device for grinding the outer diameter of textile rubber rollers. Background Technology

[0002] As a core drafting element in spinning equipment, the outer dimensional accuracy, roundness, cylindricity, and surface roughness of textile rubber rollers affect the fiber holding and conveying effect during drafting, which in turn affects yarn uniformity, hairiness, and breakage rate. Due to long-term high-speed operation, continuous pressure, and friction, the surface of rubber rollers is prone to wear, indentation, cracking, aging, and hardening, accompanied by geometrical accuracy deterioration such as radial runout and coaxiality deviation. This leads to instability in the fiber drafting process, affecting yarn quality. Therefore, it is necessary to periodically grind and dress the outer diameter of the rubber rollers during production to restore their accurate dimensions and good surface condition. Currently, the industry mostly uses ordinary cylindrical grinders or special rubber roller grinders, using grinding wheels as the grinding tool to process and dress the outer diameter of the rubber rollers.

[0003] In summary, when grinding the polyurethane elastomer coating on the surface of textile rubber rollers, the roller surface is prone to elastic indentation deformation under radial grinding force. After the grinding force is unloaded, the elastomer rebounds, causing the actual amount of material removed by grinding to be less than the set amount of material removed. This results in an excessively large outer diameter and cylindricity deviation of the rubber roller, affecting the uniformity of the contact pressure between the yarn and the rubber roller in subsequent spinning processes, and causing problems such as uneven drafting and evenness deterioration during fiber transport.

[0004] Therefore, this application provides a device for grinding the outer diameter of textile rubber rollers to meet the requirements. Summary of the Invention

[0005] The purpose of this invention is to provide a grinding device for the outer diameter of textile rubber rollers to solve the aforementioned problems. Based on the rubber hardness and grinding allowance of the rubber roller, the initial compression of the spring is adjusted via a handwheel to set the grinding pressure threshold. During the grinding process, the grinding wheel contacts the surface of the rubber roller, and the fixed rod synchronously drives the first and second extrusion plates to move. The first extrusion plate pushes the first force-bearing frame upward, causing the first extrusion roller to press against the rubber roller from the bottom. The second extrusion plate drives the sliding rod upward, and through the third extrusion plate, pushes the first inclined plate, causing the second extrusion roller to horizontally press against the rubber roller from the opposite side. Simultaneously, the second force-bearing frame acts on the second inclined plate through the connecting plate, driving the third extrusion roller to press against the rubber roller from above. The extrusion pressure of the first, second, and third extrusion rollers is consistent with the grinding pressure, forming a circumferential constraint around the grinding point. This effectively suppresses the elastic bulging deformation of the rubber roller, ensures that the actual grinding depth matches the feed rate, and improves the surface finish and dimensional consistency of the rubber roller. When the rubber roller is eccentric or has local hard spots that cause the grinding force to exceed the threshold, the floating frame drives the grinding wheel to compress the spring to achieve retraction, avoiding burning of the rubber roller surface and damage to the grinding wheel. After the high point is removed by grinding and the grinding pressure drops, the spring drive mechanism resets, realizing adaptive grinding. After the grinding process is completed, the feed mechanism returns to its original position, and each extrusion plate moves in the opposite direction, synchronously driving the extrusion roller to return to its initial position, thus solving the problems mentioned in the background technology.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0007] A grinding device for the outer diameter of a textile rubber roller includes a rubber roller grinding machine. The inner wall of the rubber roller grinding machine is slidably connected to a feeding mechanism via a linear guide rail. A first sliding frame is fixedly connected to the top of the feeding mechanism. A grinding mechanism for grinding the rubber roller is provided on the top of the first sliding frame. A support mechanism for squeezing and supporting the rubber roller is provided opposite the grinding mechanism. The feeding mechanism can slide horizontally along the inner wall of the rubber roller grinding machine to drive the first sliding frame and the grinding mechanism and support mechanism mounted on it to move as a whole, thereby adjusting the grinding position.

[0008] The grinding mechanism includes a second sliding frame, which is slidably connected to the top of the first sliding frame. A floating frame is slidably connected to the top of the second sliding frame. When performing external cylindrical grinding on the textile rubber roller, the rubber roller grinding machine is started to drive the rubber roller to rotate. At the same time, the feed mechanism is driven to move the first sliding frame towards the rubber roller side, so that the grinding wheel of the grinding equipment gradually approaches the surface of the rubber roller. After the grinding wheel contacts the rubber roller and performs grinding, the movement of the grinding equipment drives the first extrusion plate and the second extrusion plate to move towards the textile rubber roller side through the fixed rod. The grinding equipment is fixedly connected to the top of the floating frame, and a fixed block is fixedly connected to the bottom of the floating frame. The outer surface of the fixed block is slidably connected to the inner wall of the second sliding frame. A lead screw is rotatably connected to the inner wall of the second sliding frame away from the grinding equipment. The end of the lead screw passes through the second sliding frame and is fixedly connected to a handwheel.

[0009] Optionally, a sliding block is threaded onto the outer surface of the lead screw, and the outer surface of the sliding block is slidably connected to the inner wall of the second sliding frame. A compression spring is fixedly connected to one side of the outer wall of the sliding block, and the end of the compression spring away from the sliding block is fixedly connected to a fixed block. When the textile rubber roller is subjected to external cylindrical grinding, the initial preload of the compression spring can be adjusted by rotating the handwheel according to the rubber hardness of the rubber roller or the preset grinding allowance. This preload corresponds to the grinding force threshold required when the elastic deformation of the rubber roller reaches the critical value during the grinding process.

[0010] Optionally, a first fixed frame is fixedly connected to the outer wall of the second sliding frame, and a sliding groove is provided on the outer surface of the first fixed frame. A fixed rod is fixedly connected to the outer wall of the grinding equipment on the side close to the first fixed frame, and a first extrusion plate and a second extrusion plate are fixedly connected to the outer surface of the fixed rod in sequence.

[0011] Optionally, the support mechanism includes a second fixed frame, the bottom of which is fixedly connected to the first sliding frame. The outer surface of the second fixed frame is provided with a first through hole, a second through hole, and a third through hole. The outer wall of the second fixed frame near the first through hole is slidably connected to the inner wall of the slide groove.

[0012] Optionally, a first force-bearing frame is slidably connected to the inner wall of the first through hole, and a first extrusion roller is rotatably connected to the top inner wall of the first force-bearing frame via a rotating shaft. The first extrusion roller is used to support the bottom of the rubber roller. The bottom of the first force-bearing frame is slidably connected to the first extrusion plate. The pressure-bearing surface at the lower end of the first force-bearing frame is always in contact with the upper surface of the first extrusion plate. When the first extrusion plate moves horizontally to the side of the rubber roller, it squeezes and pushes the first force-bearing frame to slide upward.

[0013] Optionally, a sliding rod is slidably connected to the inner wall of the second fixing frame near the second extrusion plate, and a second force plate is fixedly connected to the bottom of the sliding rod. The second force plate is slidably connected to the outer surface of the second extrusion plate, and a third extrusion plate is provided at the end of the sliding rod away from the second force plate.

[0014] Optionally, a second force-bearing frame is slidably connected to the inner wall of the second through hole, and a first inclined plate is fixedly connected to the inner wall of the second force-bearing frame.

[0015] Optionally, the outer surface of the first inclined plate is slidably connected to the third extrusion plate, and the second force-bearing frame is rotatably connected to the end away from the first inclined plate via a rotating shaft. The second extrusion roller is used to extrude the side of the rubber roller away from the grinding equipment.

[0016] Optionally, a third force-bearing frame is slidably connected to the inner wall of the third through hole, and a third extrusion roller is rotatably connected to the bottom inner wall of the third force-bearing frame via a rotating shaft. The surfaces of the first extrusion roller, the second extrusion roller, and the third extrusion roller are all covered with an elastic layer. The hardness of this elastic layer is between that of rubber and metal on the surface of the rubber roller, which can prevent indentations from forming on the surface of the rubber roller during the extrusion process. The third extrusion roller is used to extrude the top of the rubber roller, and a second inclined plate is fixedly connected to the end of the third force-bearing frame away from the third extrusion roller.

[0017] Optionally, a third fixing frame is fixedly connected to the top of the second force-bearing frame, and a connecting plate is fixedly connected to the end of the third fixing frame away from the second force-bearing frame. The connecting plate is slidably connected to the outer surface of the second inclined plate.

[0018] Optionally, the handwheel is used to drive the lead screw to rotate, causing the sliding block to move horizontally along the inner wall of the second sliding frame. The sliding block adjusts the floating preload of the floating frame through the compression spring, which is used to adjust the grinding pressure of the grinding equipment on the rubber roller.

[0019] Compared with the prior art, the present invention has at least the following beneficial effects:

[0020] In the above-mentioned solution, the outer diameter grinding processing device for textile rubber rollers provided in this application can effectively solve the processing defects caused by uneven elastic deformation of the rubber roller by setting a support mechanism, thereby improving the processing quality and work efficiency. The support mechanism is provided with a first extrusion roller, a second extrusion roller and a third extrusion roller, which apply extrusion force simultaneously from the bottom, opposite and top of the grinding point, respectively, and make the extrusion force consistent with the grinding force, thereby suppressing the elastic swelling deformation of the rubber roller, so that the grinding force can be applied to the material cutting and removal, ensuring that the actual grinding depth matches the feed rate, thereby improving the problem of uneven local grinding, improving the surface finish, processing efficiency and dimensional consistency of the rubber roller.

[0021] Furthermore, by setting up a grinding mechanism, adaptive grinding processing can be achieved for rubber rollers that are eccentric or have local hard spots, which can effectively avoid processing defects. By rotating the handwheel to adjust the preload of the pressure spring, it can be adapted to rubber rollers with different rubber hardness and corresponding grinding allowances. The grinding force threshold can be preset. When the grinding force increases due to the eccentricity of the rubber roller or local hard spots, the floating frame drives the grinding device to retract synchronously and compress the pressure spring to avoid burning the surface of the rubber roller and damaging the grinding wheel. After the grinding force drops, the pressure spring drives the grinding equipment to reset, ensuring the stability of the grinding process and improving the reliability of the outer diameter processing of the rubber roller.

However, this is only for illustrative purposes and is not intended to limit the present invention to this specific structure, device and environment. Those skilled in the art can adjust or modify these devices and environments according to specific needs. Detailed Implementation

[0036] The following is a detailed description of the outer diameter grinding device for textile rubber rollers provided by the present invention, with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments; those skilled in the art can also use other alternative methods to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0037] It should be noted that the use of terms such as "an embodiment," "an embodiment," "an exemplary embodiment," and "some embodiments" in the specification indicates that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments (whether explicitly described or not) should be within the knowledge of those skilled in the art.

[0038] Generally, terms can be understood at least partly from their use in context. For example, depending at least partly on the context, the term "one or more" as used herein can be used to describe any feature, structure, or characteristic in a singular sense, or a combination of features, structures, or characteristics in a plural sense. Additionally, the term "based on" can be understood not necessarily to convey an exclusive set of factors, but rather, alternatively, depending at least partly on the context, to allow for the presence of other factors that are not necessarily explicitly described.

[0039] It is understood that the meanings of “on”, “above”, and “above” in this invention should be interpreted in the broadest manner, such that “on” means not only “directly on” something, but also includes the meaning of being “on” something with an intervening feature or layer, and that “above” or “above” means not only “on” something, but also includes the meaning of being “on” something without an intervening feature or layer.

[0040] Furthermore, spatially related terms such as “below,” “under,” “lower,” “above,” and “upper” are used herein for convenience to describe the relationship of one element or feature to one or more other elements or features, as illustrated in the accompanying drawings. Spatially related terms are intended to cover different orientations in the use or operation of the device other than those depicted in the accompanying drawings. The device may be oriented in other ways, and the spatially related descriptive terms used herein can be interpreted similarly.

[0041] Because the polyurethane elastomer covering the surface of textile rubber rollers has elastic properties, it is prone to elastic indentation deformation during external cylindrical grinding. At the same time, since the two ends of the rubber roller are close to the clamping and support area, the rigid constraint is strong, and the deformation of the polyurethane elastomer is limited, resulting in a relatively small elastic deformation. Due to the lack of lateral constraint in the middle section of the rubber roller, the elastomer is more prone to compression and indentation under the same radial grinding force, and its deformation will be greater than that at the ends. As a result, after the grinding force is unloaded, the elastomer rebounds, and the rebound amount in the middle section is much greater than that at the ends. This causes the actual outer diameter of the rubber roller to be larger, and the roundness and cylindricity errors of the rubber roller to increase. This will affect the uniformity of the contact pressure between the yarn and the rubber roller in subsequent spinning processes, causing quality problems such as uneven drafting and deterioration of yarn evenness.

[0042] like Figure 1 and Figure 2As shown, an embodiment of the present invention provides a grinding device for the outer diameter of a textile rubber roller, including a rubber roller grinding machine 1. A feeding mechanism 2 is slidably connected to the inner wall of the rubber roller grinding machine 1 via a linear guide rail. A first sliding frame 3 is fixedly connected to the top of the feeding mechanism 2. A grinding mechanism 4 for grinding the rubber roller is provided on the top of the first sliding frame 3. A support mechanism 5 for squeezing and supporting the rubber roller is provided opposite the grinding mechanism 4. The feeding mechanism 2 can slide horizontally along the inner wall of the rubber roller grinding machine 1 to drive the first sliding frame 3 and the grinding mechanism 4 and support mechanism 5 mounted on it to move as a whole, thereby adjusting the grinding position.

[0043] When performing external cylindrical grinding on the textile rubber roller, the rubber roller grinding machine 1 is started to drive the rubber roller to rotate. At the same time, the feed mechanism 2 is driven to move the first sliding frame 3 toward the rubber roller side, so that the grinding wheel of the grinding equipment 407 gradually approaches the surface of the rubber roller. After the grinding wheel contacts the rubber roller and performs grinding, the movement of the grinding equipment 407 drives the first extrusion plate 409 and the second extrusion plate 410 to move toward the textile rubber roller side through the fixed rod 408.

[0044] like Figure 3 and Figure 5 As shown, the grinding mechanism 4 includes a second sliding frame 401, which is slidably connected to the top of the first sliding frame 3. A floating frame 405 is slidably connected to the top of the second sliding frame 401, and a grinding device 407 is fixedly connected to the top of the floating frame 405. The grinding device 407 consists of an electric spindle and a grinding wheel connected to its end. The rotation axis of the grinding wheel is arranged parallel to the axis of the rubber roller. A fixing block 406 is fixedly connected to the bottom of the floating frame 405, and the outer surface of the fixing block 406 is connected to the second sliding frame 401. The inner wall of the second sliding frame 401 is slidably connected. A lead screw 402 is rotatably connected to the inner wall of the side of the second sliding frame 401 away from the grinding equipment 407. The end of the lead screw 402 passes through the second sliding frame 401 and is fixedly connected to a handwheel 411. A sliding block 403 is threadedly connected to the outer surface of the lead screw 402. The outer surface of the sliding block 403 is slidably connected to the inner wall of the second sliding frame 401. A compression spring 404 is fixedly connected to one side of the outer wall of the sliding block 403. The end of the compression spring 404 away from the sliding block 403 is fixedly connected to a fixed block 406.

[0045] Handwheel 411 is used to drive lead screw 402 to rotate, causing sliding block 403 to move horizontally along the inner wall of second sliding frame 401. Sliding block 403 adjusts the floating preload of floating frame 405 through compression spring 404, which is used to adjust the grinding pressure of grinding equipment 407 on rubber roller. When handwheel 411 is rotated, lead screw 402 drives sliding block 403 to move towards fixed block 406, thereby adjusting the compression of compression spring 404. The greater the compression of compression spring 404, the greater the preload applied by compression spring 404 to fixed block 406 and floating frame 405. Therefore, grinding equipment 407 needs to overcome a greater grinding reaction force to push floating frame 405 backward.

[0046] When grinding the outer diameter of a textile rubber roller, the initial preload of the pressure spring 404 can be adjusted by rotating the handwheel 411 according to the hardness of the rubber roller or the preset grinding allowance. This preload corresponds to the grinding force threshold required when the elastic deformation of the rubber roller reaches the critical value during the grinding process.

[0047] When the rubber roller has eccentricity or local hard spots, causing the grinding force to rise instantaneously, the floating frame 405 and the grinding equipment 407 move backward as a whole and compress the compression spring 404 to avoid excessive compression that could burn the surface of the rubber roller or damage the grinding wheel. After the eccentric high point is removed by grinding and the grinding force is reduced, the compression spring 404 pushes the floating frame 405 to reset, thereby realizing adaptive grinding operation for eccentric rubber rollers with local hard spots.

[0048] like Figure 6 As shown, the outer wall of the second sliding frame 401 is fixedly connected to the first fixed frame 412. The outer surface of the first fixed frame 412 is provided with a sliding groove 413. The outer wall of the grinding device 407 near the first fixed frame 412 is fixedly connected to a fixed rod 408. The outer surface of the fixed rod 408 is sequentially fixedly connected to a first extrusion plate 409 and a second extrusion plate 410.

[0049] After the rubber roller is ground to the target size, the feed mechanism 2 is operated to return, and the grinding device 407 separates from the rubber roller. During the return process, the grinding device 407 drives the first extrusion plate 409 and the second extrusion plate 410 to move in opposite directions through the fixed rod 408. Under the reset action of the first force frame 505, the second force frame 510, and the third force frame 515 respectively, the first extrusion roller 506, the second extrusion roller 512, and the third extrusion roller 517 are driven to reset, so that the first extrusion roller 506, the second extrusion roller 512, and the third extrusion roller 517 no longer extrude on the rubber roller.

[0050] Meanwhile, uneven elastic deformation of textile rollers can easily lead to uneven local grinding, reducing surface finish and affecting processing efficiency and workpiece dimensional accuracy consistency. In this embodiment, such as... Figure 7 and Figure 10 As shown, the support mechanism 5 includes a second fixed frame 501. The bottom of the second fixed frame 501 is fixedly connected to the first sliding frame 3. The outer surface of the second fixed frame 501 is provided with a first through hole 502, a second through hole 503 and a third through hole 504 respectively. The outer wall of the second fixed frame 501 near the first through hole 502 is slidably connected to the inner wall of the slide groove 413.

[0051] The inner wall of the first through hole 502 is slidably connected to a first force support frame 505. The top inner wall of the first force support frame 505 is rotatably connected to a first extrusion roller 506 via a rotating shaft. The first extrusion roller 506 is used to support the bottom of the rubber roller. The bearing surface at the lower end of the first force support frame 505 is always in contact with the upper surface of the first extrusion plate 409. When the first extrusion plate 409 moves horizontally to one side of the rubber roller, it squeezes and pushes the first force support frame 505 to slide upward.

[0052] A sliding rod 507 is slidably connected to the inner wall of the second fixed frame 501 near the second extrusion plate 410. A second force plate 508 is fixedly connected to the bottom of the sliding rod 507. The bottom surface of the second force plate 508 is slidably attached to the upper surface of the second extrusion plate 410. A third extrusion plate 509 is provided at the end of the sliding rod 507 away from the second force plate 508.

[0053] The inner wall of the second through hole 503 is slidably connected to a second force support frame 510, and the inner wall of the second force support frame 510 is fixedly connected to a first inclined plate 511. It is worth noting that the outer surface of the first inclined plate 511 is slidably connected to a third extrusion plate 509, and the front end face of the third extrusion plate 509 is in sliding fit with the inclined surface of the first inclined plate 511, thereby realizing the conversion from vertical movement to horizontal movement. The end of the second force support frame 510 away from the first inclined plate 511 is rotatably connected to a second extrusion roller 512 through a rotating shaft. The second extrusion roller 512 is used to extrude the side of the rubber roller away from the grinding equipment 407.

[0054] A third force-bearing frame 515 is slidably connected to the inner wall of the third through hole 504. A third extrusion roller 517 is rotatably connected to the bottom inner wall of the third force-bearing frame 515 via a rotating shaft. The third extrusion roller 517 is used to extrude the top of the rubber roller. A second inclined plate 516 is fixedly connected to the end of the third force-bearing frame 515 away from the third extrusion roller 517. The surfaces of the first extrusion roller 506, the second extrusion roller 512, and the third extrusion roller 517 are all covered with an elastic layer. The hardness of this elastic layer is between that of rubber and metal on the surface of the rubber roller, which can prevent indentations from forming on the surface of the rubber roller during the extrusion process. At the same time, a third fixing frame 513 is fixedly connected to the top of the second force-bearing frame 510. A connecting plate 514 is fixedly connected to the end of the third fixing frame 513 away from the second force-bearing frame 510. The connecting plate 514 is slidably connected to the outer surface of the second inclined plate 516.

[0055] When the textile rubber roller is subjected to external cylindrical grinding, the feed motion of the grinding equipment 407 synchronously drives the first extrusion plate 409 and the second extrusion plate 410 to move toward the rubber roller side via the fixed rod 408. During the feeding process of the grinding equipment 407, the first extrusion plate 409 driven by the fixed rod 408 pushes the first force frame 505 to slide upward along the first through hole 502, so that the first extrusion roller 506 presses the rubber roller from the bottom. At the same time, the second extrusion plate 410 moves synchronously, pushing the second force plate 508 and the sliding rod 507 to move upward. The third extrusion plate 509 at the upper end of the sliding rod 507 pushes the inclined surface of the first inclined plate 511, driving the second force frame 510 to move horizontally toward the rubber roller side along the second through hole 503, so that the second extrusion roller 512 presses the rubber roller from the opposite side of the grinding mechanism 4.

[0056] The horizontal movement of the second force-bearing frame 510, through the third fixed frame 513 and the connecting plate 514, pushes the inclined surface of the second inclined plate 516, thereby driving the third force-bearing frame 515 to slide down along the third through hole 504, so that the third extrusion roller 517 presses the rubber roller from the top, so that the extrusion pressure of the first extrusion roller 506, the second extrusion roller 512 and the third extrusion roller 517 on the rubber roller is consistent with the grinding pressure of the grinding equipment 407.

[0057] By applying synchronous extrusion constraints on the opposite side, bottom, and top of the grinding point, the grinding area of ​​the rubber roller is made into a circumferentially compressed state, which can effectively suppress the tendency of elastic material to bulge out to the free surface. At this time, the grinding force mainly acts on material removal rather than causing elastic deformation of the rubber roller. The actual grinding depth can be consistent with the feed rate, thereby solving the problems of uneven local grinding, reduced surface finish, decreased processing efficiency, and poor workpiece size consistency caused by uneven elastic deformation of textile rubber rollers.

Furthermore, to avoid unnecessary misunderstanding of the essence of this invention, well-known methods, processes, procedures, components, and circuits are not described in detail.
