A rubber roll grinding device

Abstract

This invention discloses a rubber roller grinding device, belonging to the field of rubber roller grinding technology, aiming to solve the technical problem of low functionality in rubber roller grinding devices. The device includes a lathe, an equidistant moving mechanism, a turning module, and a grinding module. By designing the radial length of several mounting seats A to gradually decrease from the head end to the tail end, this invention allows several turning tools to initially merge together to form a stepped cutting edge, achieving layered progressive turning. This effectively disperses cutting force and prevents excessive damage to the rubber roller surface. By controlling the equidistant movement of the slip ring, the several turning tools are separated until the cutting edges are flush. A single axial feed can simultaneously turn multiple evenly arranged parallel annular grooves on the rubber roller surface. Simultaneously, the grinding unit moves synchronously with the slip ring, enabling fine grinding of the cylindrical rubber roller surface and the annular grooves. This invention can perform integrated turning and grinding of cylindrical rubber rollers and annular grooved rubber rollers, significantly improving the functionality of the device.

Description

Technical Field

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

[0002] Rubber rollers are core components in industries such as printing, textiles, papermaking, dyeing, and lamination. Their surface roundness, cylindricity, roughness, coaxiality, and dimensional accuracy directly determine the product processing quality and equipment operational stability. Rubber rollers include cylindrical rubber rollers and annular grooved rubber rollers. Annular grooved rubber rollers are cylindrical rubber rollers with several annular grooves evenly spaced.

[0003] Traditional rubber roller grinding processes mostly employ ordinary cylindrical grinding machines, which can only perform single-function cylindrical grinding. This limited functionality and poor adaptability prevent the simultaneous completion of multiple processes such as rough grinding, fine grinding, polishing, groove forming, and end face chamfering on a single machine. In actual production, frequent changes of grinding wheels and tools, or even equipment replacement, are required for different processes. This necessitates multiple clamping, tool setting, and grinding parameter adjustments, resulting in low processing efficiency and making it difficult to guarantee dimensional accuracy, coaxiality, roundness, and other geometric tolerances due to clamping errors and repeated positioning. This makes it difficult to meet the integrated processing requirements of high-precision cylindrical and annular grooved rubber rollers. Therefore, we propose a rubber roller grinding device. Summary of the Invention

[0004] The purpose of this invention is to provide a rubber roller grinding device to solve the technical problem of low functionality of rubber roller grinding devices.

The dual-axis drive mechanism drives the heads of several turning tools to contact the surface of the rubber roller first. The lathe drives the rubber roller to rotate to achieve the first layer of cutting. Subsequently, the subsequent turning tools with progressively increasing radial heights perform the second, third, and Nth layers of cutting, forming a progressive layered turning process.

The dual-axis drive mechanism drives the heads of several turning tools to contact the surface of the rubber roller first. The lathe rotates the rubber roller to achieve the first layer of cutting. Subsequently, subsequent turning tools with progressively increasing radial heights perform the second, third, and Nth layers of cutting, forming a progressive layered turning process.

When the control slip ring moves at equal intervals on the drive shaft, it can simultaneously drive several gears to roll on the transverse tooth groove, thereby driving the mounting seat A to move radially. When the gap between adjacent slip rings increases proportionally to the maximum value, several turning tools separate from each other until the cutting edges are flush. One axial feed can simultaneously turn multiple evenly arranged parallel ring grooves on the surface of the rubber roller. Similarly, the control drive shaft drives the sleeve and slip ring to rotate synchronously by 180°, and the grinding module performs fine grinding on the ring grooves, improving the functionality of the rubber roller grinding device.

[0020] like Figures 1 to 13As shown, the present invention relates to a rubber roller grinding device, including a lathe 1, a turning module 6 and a grinding module 7. An axial moving mechanism 2 is fixed on the lathe 1, a radial moving mechanism 3 is provided at the movable end of the axial moving mechanism 2, a U-shaped seat 4 is fixed at the movable end of the radial moving mechanism 3, and an equally spaced moving mechanism 5 is provided on the U-shaped seat 4.

[0021] In embodiments of the present invention, such as Figure 3 , Figure 4 and Figure 8 As shown, the inner ends of both sides of the U-shaped seat 4 are provided with rotating grooves A41. The head end of the rotating groove A41 is provided with a sliding groove 42. The surface of the rotating groove A41 at the head end is provided with a rotating groove B43 and several slots 44. The several slots 44 are arranged in a ring with equal spacing at the head end of the rotating groove B43, and the slots 44 are connected to the rotating groove B43. The head end of the U-shaped seat 4 is fixed with a dust cover A45, and the tail end of the U-shaped seat 4 is fixed with a dust cover B46.

[0022] In embodiments of the present invention, such as Figure 3 As shown, the equidistant moving mechanism 5 includes a motor A51, a motor B52, a sleeve 53, a drive shaft 54, several slip rings 55, and a snap-fit ​​assembly 56.

[0023] In embodiments of the present invention, such as Figure 3 As shown, motors A51 and B52 are respectively housed inside dust covers A45 and B46, and motors A51 and B52 are respectively fixedly connected to both ends of U-shaped base 4.

[0024] In embodiments of the present invention, such as Figure 3 and Figure 5 As shown, the sleeve 53 is rotatably mounted on the U-shaped seat 4. Both ends of the sleeve 53 are fixed with main shafts 531. The two main shafts 531 are rotatably connected to two rotating grooves B43 respectively. A sliding cavity 532 is opened inside the sleeve 53. The surface of the sleeve 53 has a symmetrical structure with transverse grooves A533 and B534. Both transverse grooves A533 and B534 are connected to the sliding cavity 532. A transverse tooth groove 530 is opened at the end of the transverse groove A533 near the sliding cavity 532. Both ends of the transverse grooves A533 and B534 have grooves A535. A folded dustproof cloth A536 is fixed in the groove A535 at the tail end. The surface of the main shaft 531 at the head end has a ring-shaped structure with several limiting grooves 537. The several limiting grooves 537 are connected through sliding holes 538.

[0025] In embodiments of the present invention, such as Figure 3 , Figure 7 , Figure 8 and Figure 9As shown, the drive shaft 54 ​​is rotatably disposed within the slide cavity 532. The surface of the drive shaft 54 ​​has a linear, equally spaced structure with several threaded guide grooves 541. The head end gap length of any two adjacent threaded guide grooves 541 is equal, and the tail end gap length of any two adjacent threaded guide grooves 541 is equal. Moreover, the tail end gap length of any two adjacent threaded guide grooves 541 is greater than the head end gap length. Both ends of the drive shaft 54 ​​are fixedly provided with central shafts 542. The two central shafts 542 are rotatably connected to both ends of the slide cavity 532, respectively. The head end of the central shaft 542 located at the head end passes through the slide hole 538 and is fixedly provided with a snap-fit ​​gear plate A543. The tail end of the central shaft 542 located at the tail end passes through the dust cover B46 and is fixedly connected to the output shaft of the motor B52.

[0026] In embodiments of the present invention, such as Figure 3 and Figure 13 As shown, several slip rings 55 are linearly and equally spaced and sleeved on the drive shaft 54. The slip rings 55 are slidably connected to the sliding cavity 532. Each slip ring 55 has a rotatably connected ball block 551 inside it. Each ball block 551 is movably connected to several threaded guide grooves 541. Through the above arrangement, when the drive shaft 54 ​​rotates relative to the sleeve 53, some threaded guide grooves 541 rotate relative to the ball blocks 551, causing the slip rings 55 to slide along the sliding cavity 532. Through the structural design of the several threaded guide grooves 541, the guide distances of the several threaded guide grooves 541 are not equal, and the guide distances of adjacent threaded guide grooves 541 increase in an arithmetic sequence from the beginning to the end. This ensures that when the slip rings 55 move axially, the distance between adjacent slip rings 55 always satisfies this arithmetic sequence relationship, and the gap between any two adjacent slip rings 55 is equal.

[0027] In embodiments of the present invention, such as Figure 3 , Figure 5 , Figure 6 and Figure 8As shown, the snap-fit ​​assembly 56 includes a circular block 561, several snap-fit ​​blocks 562, a slider 563, and a threaded rod A566. The circular block 561 is slidably disposed in the sliding hole 538, and the several snap-fit ​​blocks 562 are respectively slidably disposed in several limiting grooves 537. The snap-fit ​​blocks 562 are all fixedly connected to the circular block 561, and the snap-fit ​​blocks 562 are engaged with the snap-fit ​​grooves 44. A snap-fit ​​toothed disc B560 is fixedly disposed at the tail end of the circular block 561. The slider 563 is slidably disposed in the slide groove 42 and engages with the toothed disc A543. The head end of the slider 563 has a threaded groove A564, and the tail end of the slider 563 is fixedly provided with a rotating shaft 565. The rotating shaft 565 is rotatably connected to the head end of the round block 561. The threaded rod A566 is rotatably disposed in the slide groove 42 and threadedly connected to the threaded groove A564. The head end of the threaded rod A566 passes through the dust cover A45 and is fixedly connected to the output shaft of the motor A51. This invention, through the structural design of the snap-fit ​​assembly 56, enables the threaded rod A566 to rotate when the output shaft of the motor A51 is controlled to rotate by an external control mechanism. This causes the slider 563 to slide relative to the slide groove 42, allowing the round block 561 and the snap-fit ​​block 562 to move synchronously. When the snap-fit ​​block 562 is at the head end of the limiting groove 537, the snap-fit ​​toothed disc B560 disengages from the snap-fit ​​toothed disc A543, and the snap-fit ​​block 562 engages with the snap-fit ​​groove 44. This prevents the snap-fit ​​block 562 and the round block 561 from rotating, thus preventing the main shaft 531, the sleeve 53, and several slip rings 55 from rotating. At this time, the output shaft of the motor B52 is controlled to rotate by an external control mechanism, causing the central shaft 542 to drive the drive shaft 54 ​​to rotate. Part of the threaded guide groove 541 moves relative to the ball block 551, causing several slip rings 55 to move at equal intervals. When the snap-fit ​​block 562 is at the head end of the limiting groove 537, the snap-fit ​​block 562 engages with the sliding groove 44, preventing the round block 561 from rotating. At the end of step 37, the locking block 562 disengages from the slot 44 and fully enters the rotating groove B43. The locking gear plate B560 engages with the locking gear plate A543, allowing the locking block 562 and the round block 561 to rotate. This enables the main shaft 531, the sleeve 53, and several slip rings 55 to rotate synchronously. At this time, the output shaft of the motor B52 is controlled to rotate by an external control mechanism. The central shaft 542 drives the drive shaft 54 ​​to rotate, and the locking gear plate A543 drives the locking gear plate B560, the round block 561, and the locking block 562 to rotate. This allows the main shaft 531, the sleeve 53, and several slip rings 55 to rotate synchronously with the drive shaft 54. During processing, the locking block 562 is engaged with the slot 44, limiting the sleeve 53 and preventing the output shafts of the motor A51 and the motor B52 from being directly subjected to force, thus ensuring the service life of the device.

[0028] In embodiments of the present invention, such as 10, Figure 11 and Figure 12As shown, the turning module 6 includes several mounting seats A61 and several threaded rods B62. The mounting seats A61 are movably disposed within the transverse groove A533, and their radial length gradually decreases from the head end to the tail end. The threaded rods B62 are rotatably disposed on the surfaces of several slip rings 55 and are threadedly connected to the mounting seats A61. Gears 63 are fixedly mounted on the threaded rods B62 and mesh with the transverse tooth groove 530. This invention, through the structural design of the turning module 6, such as... Figure 3 As shown, in the initial state, two adjacent mounting seats A61 are in contact. Since the radial length of several mounting seats A61 gradually decreases from the head to the tail, i.e., the radial length of the mounting seat A61 at the head is the longest and the radial length of the mounting seat A61 at the tail is the shortest, the radial extension height of several mounting seats A61 decreases in an arithmetic progression from the head to the tail, forming a stepped distribution of high head and low tail for machining the surface of the rubber roller. During machining, the mounting seat A61 at the lowest tail first contacts the surface of the rubber roller for the first layer of cutting, the mounting seat A61 at the next lowest head performs the second layer of cutting, and so on, achieving layered machining. Each layer of mounting seat A61 removes a small amount of rubber material from the surface of the rubber roller, thus dispersing the cutting force and preventing excessive damage to the surface of the rubber roller. The drive shaft 54 ​​is controlled to rotate relative to the sleeve 53, and the ball block 551 slides along a portion of the threaded guide groove 541 from the head to the tail. Since the guide distance of several portions of the threaded guide groove 541 increases in an arithmetic progression from the head to the tail, two adjacent... The axial clearance of the slip ring 55 increases proportionally. When the ball block 551 slides to the end of part of the threaded guide groove 541, the axial clearance between two adjacent slip rings 55 reaches its maximum value. At this time, the axial distance between two adjacent mounting seats A61 is also at its maximum value, and each mounting seat A61 separates from each other. At the same time, as the slip ring 55 moves axially, the gear 63 rolls along the transverse tooth groove 530 and drives the mounting seat A61 to move radially, so that the radial length of each mounting seat A61 is adjusted to be flush. Multiple mounting seats A61 are arranged at equal intervals and have the same radial length, forming a flush separation turning shape. Multiple evenly arranged parallel annular grooves can be turned on the surface of the rubber roller at the same time with one axial feed. The depth of the annular groove is controlled by the feed amount of the radial movement mechanism 3, and the width of the annular groove can be controlled by the movement of the axial movement mechanism 2. Through the layered progressive turning of the initial shape and the synchronous annular groove turning of the separation shape, columnar rubber rollers and annular grooved rubber rollers can be turned, improving the functionality of the rubber roller grinding device.

[0029] In embodiments of the present invention, such as Figure 11As shown, the mounting base A61 has a threaded groove B612 at one end near the sliding cavity 532. The threaded groove B612 is threadedly connected to the threaded rod B62. The end of the mounting base A61 away from the threaded groove B612 extends through the transverse groove A533 and is detachably and fixedly connected to a turning tool 64. Through the above arrangement, when the threaded rod B62 rotates relative to the threaded groove B612, the mounting base A611 drives the turning tool 613 to move radially along the transverse groove A533.

[0030] In embodiments of the present invention, such as 10 and Figure 12 As shown, the grinding module 7 includes several mounting seats B71, all of which are slidably disposed on the transverse groove B534. Each mounting seat B71 is fixedly connected to the surface of a number of slip rings 55. One end of each mounting seat B71, away from the sliding cavity 532, extends through the transverse groove B534 and is detachably and fixedly connected to a grinding block 72. Through the structural design of the grinding module 7, this invention enables the mounting seats B71 and the slip rings 55 to move synchronously, allowing the grinding module 7 to possess both a flush overall grinding configuration and a flush separate grinding configuration, used for grinding the surface of the rubber roller and the annular groove on the rubber roller surface, respectively, further enhancing the functionality of the rubber roller grinding device.

[0031] In embodiments of the present invention, such as 10 and Figure 11 As shown, both ends of mounting base A61 and mounting base B71 are provided with grooves B614. The two grooves B614 at the tail end are respectively fixedly connected to two dustproof cloths A536. Folded dustproof cloths B615 are fixedly installed on the grooves B614 at the head end of mounting base A61 and B71. The two dustproof cloths B615 at the head end are respectively fixedly connected to the two grooves A535 at the head end, and the remaining dustproof cloths B615 are fixedly connected to their corresponding grooves B614. Through the above-mentioned arrangement, the present invention uses dustproof cloths A536 and B615 to prevent debris from entering the sliding cavity 532.

[0032] Working principle: This embodiment provides a rubber roller grinding device. When in use, the rubber roller to be processed is clamped on the lathe 1. The lathe 1 controls the rubber roller to rotate around its own axis. The axial movement mechanism 2 and the radial movement mechanism 3 respectively control the U-shaped seat 4 to move along the axial and radial directions of the rubber roller. In the initial state, the snap-fit ​​block 562 of the snap-fit ​​assembly 56 snaps into the snap-fit ​​groove 44, the sleeve 53 and slip ring 55 cannot rotate, the adjacent mounting seats A61 are in contact, and the radial height of each turning tool 64 is distributed in a stepped shape with a low head and a high tail. The U-shaped seat 4 is driven to the appropriate position by the radial movement mechanism 3, and the U-shaped seat 4 is driven to move along the axial direction of the rubber roller by the axial movement mechanism 2. The lathe 1 drives the rubber roller to rotate, and the turning tool 64 at the head end with the lowest radial height first contacts the surface of the rubber roller to perform the first layer of cutting. Subsequently, the subsequent turning tools 64 with the radial height increasing sequentially perform the second, third and Nth layers of cutting, forming a progressive layered turning process to complete the roughing of the outer circle of the rubber roller. After rough machining is completed, the turning tool 64 is disengaged from the surface of the rubber roller. The output shaft of the motor A51 is rotated by the external control mechanism. The threaded rod A566 drives the slider 563 to slide along the slide groove 42. The round block 561 and the snap-fit ​​block 562 move synchronously, so that the snap-fit ​​block 562 disengages from the slot 44. The snap-fit ​​gear plate B560 snaps into the snap-fit ​​gear plate A543. The output shaft of the motor B52 is rotated by the external control mechanism. The drive shaft 54 ​​drives the snap-fit ​​gear plate A543, the snap-fit ​​gear plate B560, the round block 561, the snap-fit ​​block 562, the spindle 531, the sleeve 53, and the slip ring 55 to rotate synchronously by 180°, so that the grinding module 7 rotates to the original working position of the turning module 6, and the turning module 6 rotates to the opposite side. The radial moving mechanism 3 drives the U-shaped seat 4 to move until the grinding block 72 contacts the outer surface of the rubber roller. The axial moving mechanism 2 drives the U-shaped seat 4 to reciprocate along the axial direction of the rubber roller. The grinding block 72 performs fine grinding on the outer surface of the rubber roller to obtain a high-gloss cylindrical rubber roller surface. If only the cylindrical rubber roller needs to be processed, the processing is now complete. If it is necessary to process evenly arranged annular grooves on the surface of the rubber roller, the output shaft of motor A51 is rotated by the external control mechanism, so that the locking block 562 moves to the head end of the limiting groove 537. The locking block 562 engages with the groove 44, and the sleeve 53 and slip ring 55 are locked and cannot rotate. The output shaft of motor B52 is rotated by the external control mechanism, and the drive shaft 54 ​​rotates relative to the sleeve 53. The ball block 551 slides from the head end to the tail end along part of the threaded guide groove 541. Since the guide distance of several parts of the threaded guide groove 541 increases in an arithmetic sequence from the head end to the tail end, the gap between adjacent slip rings 55 increases proportionally to the maximum value, and the axial distance between adjacent mounting seats A61 is also the maximum value. Each mounting seat A61 is separated from each other. At the same time, when the slip ring 55 moves axially, the gear 63 rolls along the transverse tooth groove 530 and drives the mounting seat A61 to move radially, so that the radial height of each turning tool 64 is adjusted to be flush, forming a separated and flush shape. After the adjustment is completed, the output shaft of motor A51 is rotated by the external control mechanism, so that the snap block 562 moves to the end of the limit groove 537, the snap block 562 disengages from the slot 44, and the snap toothed disc B560 snaps into the snap toothed disc A543. The output shaft of motor B52 is rotated by the external control mechanism, and the drive shaft 54 ​​drives the sleeve 53 and slip ring 55 to rotate synchronously by 180°, so that the turning module 6 rotates to the working position. After the turning module 6 is rotated to the working position, the U-shaped seat 4 is driven to feed radially to the preset annular groove depth through the radial moving mechanism 3. The lathe 1 drives the rubber roller to rotate. Each turning tool 64 is arranged at equal intervals and has the same radial height. The U-shaped seat 4 is driven to move along the rubber roller axis through the axial moving mechanism 2 to control the annular groove width. After the annular groove is turned, the output shaft of motor B52 is rotated by an external control mechanism. Drive shaft 54 ​​drives sleeve 53 and slip ring 55 to rotate 180° synchronously, so that grinding module 7 rotates to the working position. After the grinding module 7 rotates to the working position, each grinding block 72 is separated and aligned with the slip ring 55. The radial moving mechanism 3 drives the U-shaped seat 4 to feed radially, so that the grinding block 72 contacts the inner surface of the ring groove. The lathe 1 drives the rubber roller to rotate, and the axial moving mechanism 2 drives the U-shaped seat 4 to move along the axial direction of the rubber roller, so that the grinding block 72 grinds both ends of the ring groove, and so that several grinding blocks 72 simultaneously perform fine grinding on multiple ring grooves on the surface of the rubber roller.
