Description

Technical Field

[0001] The invention relates to the technical field of cutting equipment, in particular to a lathe for manufacturing a vacuum roller of a papermaking machine. Background Art

[0002] The papermaking industry is closely tied to national economic development and boasts a complete and vibrant ecosystem. As market demand for paper products increases, papermakers are also demanding higher efficiency. To improve papermaking efficiency, paper mills generally adopt wider papermaking widths and faster lathe speeds. Increasing papermaking widths also requires increasing the length of the vacuum rollers on papermaking lathes. The production of vacuum rollers requires multiple steps, including blanking, rough turning, finish turning, and surface treatment.

[0003] During cutting, the roller blank is cut according to the size requirements. In the existing cutting technology, the roller blank is kept in place during cutting, and then the roller body is separated and cut using a circular cutting blade. However, since the interior of the cylinder is hollow, when the edge of the cutting blade moves into the interior of the cylinder, part of the blade is always in vain and does not actually cut the pipe. The actual cut part has a smaller contact area with the thickness of the cylinder, which ultimately reduces the overall cutting efficiency. Therefore, a cutting lathe for roller blanks is needed to improve the cutting efficiency of rollers. Summary of the Invention

DETAILED DESCRIPTION

[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

For ease of illustration, when describing the embodiments of the present invention, cross-sectional views illustrating device structures may be partially enlarged and not to scale. Furthermore, the schematic diagrams are merely illustrative and should not limit the scope of protection of the present invention. Furthermore, in actual production, the three-dimensional dimensions of length, width, and depth should be included. Example 1

[0030] Reference Figure 1~Figure 2 , which is a first embodiment of the present invention, provides a lathe for manufacturing a vacuum roller of a paper machine, comprising a bed 1, a tool holder 2 is fixedly provided at the top middle portion of the bed 1, an annular cutting knife 3 is rotatably provided inside the tool holder 2, and the blade of the annular cutting knife 3 faces the center of a circle;

[0031] The cutting mechanism 4 is used to control the annular cutting blade 3 to cut the roller blank, and includes a driving member 41 provided on the side of the annular cutting blade 3, a heat sink 42 provided on both sides of the blade holder 2, and a cleaning member 43 provided on one side of the heat sink 42;

[0032] The rotating mechanism 5 is used to rotate the workpiece to speed up the cutting efficiency. It includes clamping members 51 arranged on both sides of the tool holder 2, a rotating member 52 arranged above the clamping member 51 and an adjusting member 53 arranged at the bottom of the bed 1.

[0033] The annular cutting blade 3 is a non-standard part. To meet the requirements of cutting strength, its material should be hard alloy. Example 2

[0034] Reference Figure 3 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the driving member 41 includes a ring gear 411, a gear 412, and a motor 413. The ring gear 411 is sleeved and fixedly set on the side of the annular cutting knife 3, the gear 412 is engaged with the ring gear 411, the motor 413 is located on the side of the tool holder 2 and fixedly set on the top of the bed 1, and the center of the gear 412 is sleeved on the movable end of the motor 413.

[0035] The size and position relationship between the gear 1 412 and the ring gear 1 411 shown in the figure is only for illustration. In the actual selection of the gear 1 412 , the transmission ratio of the ring gear 1 411 to the gear 1 412 meets the high speed requirement of the annular cutting blade 3 .

[0036] The heat sink 42 includes a water storage ring 421, a water dividing grid 422, a gear ring 2 423, a gear 2 424, a gear 3 425 and a water retaining frame 426. The water storage ring 421 is provided in a pair and is symmetrically arranged on both sides of the tool holder 2. The water storage ring 421 is rotatably set on the side of the tool holder 2. The water dividing grid 422 is arranged inside the water storage ring 421 and is separated by multiple narrow plates. The side of the water dividing grid 422 close to the annular cutting knife 3 is not sealed, and the side away from the annular cutting knife 3 is sealed by the side of the water storage ring 421.

[0037] The gear ring 2 423 is sleeved and fixedly arranged on the side of each water storage ring 421, and a rotating shaft is arranged at the center of the gear 2 424. The gear 2 424 is engaged with the gear ring 1 411. The rotating shaft of the gear 2 424 is rotatably arranged on the side of the tool holder 2 through the bracket. The gear 3 425 is provided with a pair of coaxial and fixedly arranged at both ends of the rotating shaft of the gear 2 424. The gear 3 425 is engaged with the gear ring 2 423. The water retaining frame 426 is fixedly arranged on the top of the bed 1, and the water retaining frame 426 is located on the outside of the tool holder 2.

[0038] Among them, the water retaining frame 426 is mainly used to prevent the cooling water in the water storage ring 421 from being thrown out of the lathe. After being blocked by the water retaining frame 426, the thrown out cooling water can be collected and collected, and then recycled.

[0039] The cleaning part 43 includes an arc-shaped plate 431, an elastic plate 432 and a water flow hole 433. The arc-shaped plate 431 is fixedly arranged on the inner side of the water retaining frame 426. The arc-shaped plate 431 is located on the inner side of the annular cutting knife 3. A baffle is provided at the edge of the arc-shaped plate 431. The elastic plate 432 is provided with multiple and fixedly arranged on the surface of the arc-shaped plate 431. One end of the elastic plate 432 away from the arc-shaped plate 431 abuts against the inner side of the water dividing grid 422, and the water flow hole 433 is opened on the side of the elastic plate 432.

[0040] During use, the driving member 41 is used to drive the annular cutting blade 3 to rotate so as to cut the workpiece, while the heat dissipating member 42 is used to dissipate heat for the annular cutting blade 3 and the workpiece.

[0041] When cutting a workpiece, a worker turns on motor 1 413. Once motor 1 413 is started, it drives gear ring 1 411 to rotate via gear 1 412, which in turn drives annular cutter 3 to rotate at high speed. During the cutting operation, the workpiece and the blade of annular cutter 3 are arranged tangentially. Compared to traditional circular blades, after the annular cutter 3 penetrates a certain thickness of the workpiece, its contact area with the interior of the workpiece is larger than that of a circular blade, thus achieving higher cutting efficiency.

[0042] Compared to traditional circular cutting blades, the annular cutting blade 3 has a smaller heat dissipation area, so certain heat dissipation requirements are met. During the cutting operation, cooling water is usually sprayed directly between the blade and the workpiece. In this device, however, the cooling water flows into the water storage ring 421. At the same time, the rotation of the annular cutting blade 3 drives the rotation of gear 2 424, which in turn drives the rotation of the two gears 3 425. Gear 3 425 in turn drives the water storage ring 421 through gear ring 2 423. The rotation speed of the water storage ring 421 is relatively high. The cooling water in the water storage ring 421 is divided into multiple parts by the water diversion grid 422. The cooling water in each water diversion grid 422 is subjected to the centrifugal force when the water storage ring 421 rotates. Therefore, some cooling water can rotate with the water storage ring 421, thereby ensuring a longer contact time between the cooling water and the annular cutting blade 3, thereby improving the heat dissipation capacity of the heat sink 42 for the annular cutting blade 3.

[0043] Furthermore, when the lathe cuts the workpiece, metal powder will be generated, and since some cooling water will be retained in the water storage ring 421, this part of cooling water will capture some metal powder into the water diversion grid 422 as the water storage ring 421 rotates. This part of metal powder sinks to the bottom under the action of centrifugal force, and then occupies the capacity of the water diversion grid 422, which will not only cause the cooling water capacity in the water diversion grid 422 to decrease, but also further reduce the heat absorption capacity of the cooling water.

[0044] In order to ensure the cooling water's ability to dissipate heat for the blade, when the water storage ring 421 rotates to the upper half of the tool holder 2, some cooling water and metal powder will fall into the curved plate 431, and then this part of the cooling water will brush the metal powder out of the curved plate 431, wherein the water flow hole 433 prevents the powder from accumulating on the side of the elastic plate 432; for those powders that sink to the bottom of the water dividing grid 422, they cannot fall out of the water storage ring 421 due to the influence of centrifugal force. At this time, the elastic plate 432 can play a role. It can continuously bounce under the resistance of the narrow plate at the edge of the water dividing grid 422, and further poke the powder on the inner wall of the water storage ring 421 during the bouncing process, thereby loosening the powder on the inner wall of the water storage ring 421 and falling onto the curved plate 431, and finally being flushed out of the curved plate 431 by the cooling water.

[0045] The remaining structures are the same as those of Example 1. Example 3

[0046] Reference Figures 4 to 6, which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: the clamping member 51 includes a rotating frame 511, a rotating cylinder 512, a third gear ring 513, a rotating disk 514, a spiral groove 515, a clamping block 516, a rubber ring 517 and a fixed screw 518. The rotating frame 511 passes through and is slidably arranged on the top of the rotating frame 511, the rotating cylinder 512 is rotatably arranged on the inner side of the rotating frame 511, and the third gear ring 513 is sleeved and fixedly arranged on one end of the rotating cylinder 512 close to the tool holder 2.

[0047] The rotating disk 514 is sleeved and fixedly arranged on the end of the rotating cylinder 512 away from the tool holder 2, the spiral groove 515 is opened on the side of the rotating disk 514, three clamping blocks 516 are provided and evenly surround the side of the rotating disk 514 along the rotating cylinder 512, the side of the clamping block 516 is engaged with the spiral groove 515, the rubber ring 517 is sleeved on the side of the rotating cylinder 512, one end of the fixing screw 518 passes through the side of the rotating disk 514 and is threadedly connected to the rotating disk 514, and the other end abuts against the side of the rubber ring 517.

[0048] Among them, there are two groups of clamping members 51 and they are symmetrically arranged on both sides of the tool holder 2, and the rotating cylinders 512 of the two groups of clamping members 51 are coaxially arranged; the fixed screw 518 plays a reinforcing role after abutting against the rubber ring 517, and the rubber ring 517 uses friction to prevent the fixed screw 518 and the rotating cylinder 512 from rotating relative to each other, and the rubber ring 517 can generate a rebound force on the fixed screw 518 after being squeezed, thereby increasing the friction between the fixed screw 518 and the rotating disk 514, thereby avoiding the loosening of the fixed screw 518 during processing.

[0049] The rotating member 52 includes a fixing frame 1 521, a fixing frame 2 522, a motor 2 523, a gear 4 524 and a toothed belt 525. The fixing frame 1 521 and the fixing frame 2 522 are respectively arranged on both sides of the tool holder 2. The motor 2 523 is fixedly arranged on the inner side of the fixing frame 1 521. The movable end of the motor 2 523 is rotatably arranged on the side of the fixing frame 2 522. There are two gears 4 524 and both are sleeved on the side of the movable end of the motor 2 523. Each gear 4 524 is connected to the gear ring 3 513 through a toothed belt 525.

[0050] The second motor 523 is provided with a brake, the function of which is to prevent the second motor 523 from rotating when the power is off.

[0051] The adjusting member 53 includes a connecting plate 531, a motor three 532 and an adjusting screw 533. The bottoms of the rotating frame 511, the fixed frame one 521 and the fixed frame two 522 all pass through the top of the bed 1 and extend to the other side. The connecting plate 531 is fixedly connected to the ends of the rotating frame 511, the fixed frame one 521 and the fixed frame two 522 extending out of the bed 1. The motor three 532 is fixedly set at the bottom of the bed 1 through a bracket. The adjusting screw 533 is fixedly set at the movable end of the motor three 532 through a coupling. The adjusting screw 533 passes through the connecting plate 531 and is threadedly connected to the connecting plate 531. The end of the adjusting screw 533 away from the motor three 532 is rotatably set at the bottom of the bed 1.

[0052] When in use: The main function of the rotating mechanism 5 is to help the workpiece rotate, wherein the clamping member 51 is used to clamp the workpiece, the rotating member 52 is used to provide power for the rotation of the workpiece, and the adjusting member 53 drives the workpiece to move to facilitate cutting.

[0053] First, place the cylindrical workpiece into the two rotating cylinders 512, and then place the part to be cut on the blade. Then the staff rotates the rotating disk 514 through the fixed screw 518. Driven by the spiral groove 515, the three clamping blocks approach the workpiece and finally clamp the workpiece at the center of the rotating cylinder 512, thereby achieving the purpose of fixing the workpiece.

[0054] The operator then turns on motor 2 523, which drives two gears 4 524 to rotate. Gears 4 524, via toothed belt 525, drive rotating drum 512, thereby rotating the workpiece. Simultaneously, motor 3 532, using adjustment screw 533, slowly moves the workpiece downward, ensuring a complete cut. It's important to note that motor 2 523 should be set to a slow speed to prevent excessive vibration in the workpiece, which could damage the blade.

[0055] During the above process, the rotation of the workpiece enables the blade of the annular cutting knife 3 to always be in contact with all surfaces of the workpiece, which can not only avoid the blade from doing work in vain, but also speed up the cutting of the workpiece by the blade. Driven by the adjusting screw 533, the workpiece slowly moves downward so that the workpiece can be completely cut. The rotation of the tool and the external processing part make the overall cutting process faster, thereby increasing the production efficiency of the vacuum roller.

[0056] The remaining structures are the same as those of Example 2.
