Description

Technical Field

[0001] This utility model relates to the field of mechanical processing technology, specifically to an insulating paper tube rolling device. Background Technology

[0002] A sheet metal rolling machine is a specialized piece of equipment used to process sheet metal into cylindrical or cylindrical workpieces. It is widely used in the manufacture of cylindrical components such as ventilation ducts, transformer insulating paper tubes, and oil tanks. The working rollers apply continuous plastic deformation to the sheet metal, gradually bending it into a nearly closed cylindrical structure. The equipment is usually equipped with a liftable upper roller to accommodate sheet metal of different thicknesses. Existing rolling devices include an upper roller and a lower roller. When processing large insulating paper tubes for transformers, the insulating paperboard is first beveled, and then the sheet metal is passed between the upper and lower rollers. Under the pressure of the upper roller and the rotation of the lower roller, the sheet metal is squeezed, bent, and deformed into a cylindrical structure. Then, the support at one end of the upper roller is removed, leaving one end of the upper roller as a free end, and the rolled sheet metal is then removed from the upper roller.

[0003] However, existing sheet metal rolling machines often require manual installation and removal of the upper roller support. Manually removing the support is time-consuming and labor-intensive, and removing the rolled insulating paper tube is inconvenient. This solution addresses this technical problem. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an insulating paper tube rolling device. A release component is incorporated into the upper roller support mechanism. The release component's reduction motor drives a slider along a guide groove via a screw. The slider moves the support seat on the connecting block, thus achieving the engagement and disengagement of the support seat from the upper roller. This avoids the support seat obstructing or interfering with the disassembly of the rolled insulating paper tube. The support seat is easy and quick to install and disassemble, improving the efficiency of the paper tube rolling process.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an insulating paper tube rolling device, including a base, two lower rollers rotatably arranged on the base in the same direction, an upper roller arranged above the two lower rollers, a lower roller driving mechanism for driving the lower rollers to rotate, and an upper roller support mechanism connected to the upper roller. The lower roller driving mechanism and the upper roller support mechanism are respectively arranged on the base, and the sheet metal passes between the upper roller and the lower rollers.

[0006] The upper roller support mechanism includes a support frame and a release assembly that can be lifted and lowered on the base. The two ends of the upper roller are respectively rotatably mounted on the support frame and the release assembly.

[0007] The disengagement assembly includes a guide groove that can be raised and lowered on the base, a slider that is horizontally slidably disposed in the guide groove, and a connecting block with one end hinged to one end of the slider. The other end of the connecting block is provided with a support seat for supporting the upper roller. The connecting block is detachably disposed in the guide groove, and the upper roller is detachably connected to the support seat.

[0008] One end of the guide groove is provided with a reduction motor for driving the slider to slide. The output shaft of the reduction motor is connected to a screw. The side of the slider is provided with an internal thread, and the screw is threadedly connected to the slider.

[0009] The bottom edge of the other end of the guide groove is provided with a guide arc surface for guiding the connecting block into the guide groove, and the bottom side of the connecting block slides in contact with the guide arc surface.

[0010] An electric cylinder is provided at the bottom of the base. The telescopic end of the electric cylinder is connected to the bottom of the guide groove. A guide rod is provided at both ends of the guide groove on the bottom side of the base. Positioning sleeves are provided on both sides of the guide groove. The positioning sleeves are vertically slidably mounted on the guide rods.

[0011] A positioning nut for adjusting the height of the guide groove is sleeved on the outer side of the guide rod, and the positioning nut is detachably abutted against the bottom side of the positioning sleeve.

[0012] The support base is provided with a through hole for accommodating the upper roller, and the through hole has a flared opening on the side near the upper roller.

[0013] The base has upright supports on both sides of the support frame. The support frame is vertically slidably disposed between the two upright supports. An electric cylinder is provided on the top side of the base. The telescopic end of the electric cylinder is connected to the support frame.

[0014] A guide rod is vertically arranged between the two upright supports. The guide rod slides through the bottom side of the support frame, and a positioning nut for adjusting the height of the support frame is sleeved on the outer side of the guide rod.

[0015] The base has a support 1 and a support 2 at both ends for supporting the lower roller. A platform is provided on the base. The lower roller driving mechanism includes a reduction motor 2 on the platform, a gear 1 connected to the driving end of the reduction motor 2, and gears 2 respectively provided at the two ends of the lower rollers. The gear 1 meshes with the two gears 2 respectively.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] (1) A release component is set by the upper roller support mechanism. The deceleration motor of the release component drives the slider to slide along the guide groove through the screw. The slider drives the support seat on the connecting block to move, thereby realizing the connection and release of the support seat and the upper roller. This avoids the support seat blocking and interfering with the disassembly of the rolled insulating paper tube. The installation and disassembly of the support seat is convenient and quick, which improves the efficiency of the plate rolling process.

[0018] (2) The guide groove is raised and lowered by electric cylinder one, and the support frame is raised and lowered by electric cylinder two, so that the two ends of the upper roller are raised and lowered synchronously. The working height of the upper roller is adjusted and limited by positioning nut one and positioning nut two, so that the height adjustment of the two ends of the upper roller is more precise, and the rolling processing accuracy and efficiency of the plate are improved.

[0019] (3) By setting the guide arc surface, the connecting block can enter the guide groove more smoothly. By setting the bell mouth inside the through hole, the upper roller can pass through the through hole more smoothly, thereby improving the reliability of the disengagement component operation and making the rolling device operate stably and reliably.

[0029] To more clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0030] See Figures 1-8 An insulating paper tube rolling device includes a base 1, two lower rollers 2 rotatably mounted on the base 1, an upper roller 3 mounted above the two lower rollers 2, a lower roller driving mechanism 4 for driving the lower rollers 2 to rotate, and an upper roller support mechanism 5 connected to the upper roller 3. The lower roller driving mechanism 4 and the upper roller support mechanism 5 are respectively mounted on the base 1, and a sheet 6 passes between the upper roller 3 and the lower rollers 2.

[0031] The upper roller support mechanism 5 includes a support frame 51 that can be lifted and lowered on the base 1 and a release component 52. The two ends of the upper roller 3 are respectively rotatably mounted on the support frame 51 and the release component 52.

[0032] The disengagement assembly 52 includes a guide groove 521 that can be raised and lowered on the base 1, a slider 522 that is horizontally slidably disposed in the guide groove 521, and a connecting block 523 that is hinged to one end of the slider 522. The other end of the connecting block 523 is provided with a support seat 524 for supporting the upper roller 3. The connecting block 523 is detachably disposed in the guide groove 521, and the upper roller 3 is detachably connected to the support seat 524.

[0033] One end of the guide groove 521 is provided with a geared motor 525 for driving the slider 522 to slide. The output shaft of the geared motor 525 is connected to a screw 526. The side of the slider 522 is provided with an internal thread, and the screw 526 is threadedly connected to the slider 522.

[0034] The bottom edge of the other end of the guide groove 521 is provided with a guide arc surface 5211 for guiding the connecting block 523 into the guide groove 521. The bottom side of the connecting block 523 slides in contact with the guide arc surface 5211, and the length of the top edge of the guide groove 521 and the guide arc surface 5211 is less than the length of its bottom edge, so as to avoid the movement of the connecting block 523 and avoid the influence of the top edge of the guide groove 521 on the movement of the connecting block 523.

[0035] An electric cylinder 527 is provided at the bottom of the base 1. The telescopic end of the electric cylinder 527 is connected to the bottom of the guide groove 521. Guide rods 528 are provided at both ends of the guide groove 521 on the bottom side of the base 1. Positioning sleeves 529 are provided on both sides of the guide groove 521. The positioning sleeves 529 are vertically slidably mounted on the guide rods.

[0036] A positioning nut 5281 for adjusting the height of the guide groove 521 is sleeved on the outer side of the guide rod 528. The positioning nut 5281 is detachably abutted against the bottom side of the positioning sleeve 529.

[0037] The support base 524 is provided with a through hole 5241 for accommodating the upper roller 3, and a flared opening 5242 is provided on the side of the through hole 5241 near the upper roller 3.

[0038] The base 1 is provided with upright supports 511 on both sides of the support frame 51. The support frame 51 is vertically slidably disposed between the two upright supports 511. The top side of the base 1 is provided with an electric cylinder 512. The telescopic end of the electric cylinder 512 is connected to the support frame 51.

[0039] A guide rod 513 is vertically arranged between the two upright supports 511. The guide rod 513 slides through the bottom side of the support frame 51. A positioning nut 514 for adjusting the height of the support frame 51 is sleeved on the outside of the guide rod 513.

[0040] The base 1 has a support 11 and a support 12 for supporting the lower roller 2 at both ends. The base 1 has a platform 13. The lower roller drive mechanism 4 includes a reduction motor 41 on the platform 13, a gear 42 connected to the drive end of the reduction motor 41, and gears 43 respectively on one end of the two lower rollers 2. The gear 42 meshes with the two gears 43 respectively.

[0041] The base 1 is equipped with a controller connected to the power supply. Gear motor 1 525, gear motor 2 41, electric cylinder 1 527, and electric cylinder 2 512 are all electrically connected to the controller.

[0042] The specific working process of this utility model:

[0043] In use, start electric cylinder 527 and electric cylinder 512 respectively. Through the support frame 51 and the support seat 524 on the guide groove 521, the upper roller 3 is driven to rise. Tighten and adjust positioning nuts 5281 and positioning nuts 514 so that positioning nuts 5281 and positioning nuts 514 are at the same set height as the bottom plate. Then place the end of the plate 6 between the upper roller 3 and the lower roller 2. Then start electric cylinder 527 and electric cylinder 512 again to drive the upper roller 3 to fall until the support frame 51 abuts against the upper end face of positioning nut 514 and the positioning sleeve 529 of the guide groove 521 abuts against the upper end face of positioning nut 5281. At this time, the upper roller 3 reaches the working height for processing the plate 6. The upper roller 3 performs preliminary compression, bending and deformation on the plate 6.

[0044] Start the second gear motor 41. The second gear motor 41 drives the two gears 43 to rotate simultaneously through the first gear 42. The gears 43 drive the two lower rollers 2 to rotate in the same direction. Under the squeezing action of the upper roller 3, the plate 6 is rolled into the space between the upper roller 3 and the lower roller 2. The plate 6 is continuously squeezed and bent under the squeezing action of the upper roller 3 and the conveying action of the lower roller 2. After the plate 6 is squeezed and bent into shape, it forms a cylinder and is sleeved on the outside of the upper roller 3.

[0045] At this point, stop the second reduction motor 41 and start the first reduction motor 525, so that one end of the upper roller 3 is suspended as a free end, so that the rolled insulating paper tube 6 can be removed. For details, see... Figures 5-8 The geared motor 525 is started, which drives the screw 526 to rotate. Driven by the screw 526, the slider 522 slides along the guide groove 521. The slider 522 drives the connecting block 523 to slide away from the upper roller 3. The support seat 524 on the connecting block 523 disengages from the upper roller 3, leaving one end of the upper roller 3 in a suspended, free state. The slider 522 continues to drive the connecting block 523 to slide until the connecting block 523 is completely disengaged from the guide groove 521. (See [link]). Figure 8 Under the weight of the support 524, the connecting block 523 rotates and swings clockwise downwards along the slider 522. At this time, the support 524 is completely below the horizontal plane of the bottom side of the upper roller 3, avoiding obstruction and interference to the disassembly of the plate 6. After stopping the deceleration motor 525, the plate 6 is held and removed from the free end of the upper roller 3 to complete the rolling process of the entire plate 6.

[0046] Then, the reverse start of the reduction motor 525 causes the slider 522 to drive the connecting block 523 to slide to the side of the upper roller 3. When the bottom of the connecting block 523 contacts the guide arc surface 5211 of the guide groove 521, the connecting block 523 rotates and swings counterclockwise along the slider 522. The slider 522 continues to slide until the connecting block 523 is guided into the guide groove 521. At this time, the connecting block 523 is in a horizontal state and the support seat 524 is in a vertical state. The slider 522 continues to slide, and the upper roller 3 is guided from the flared mouth 5242 into the through hole 5241, completing the connection between the support seat 524 and the upper roller 3. Then, the next plate 6 can be rolled.

[0047] The upper roller support mechanism 5 is equipped with a disengagement component 52. The reduction motor 525 of the disengagement component 52 drives the slider 522 to slide along the guide groove 521 through the screw 526. The slider 522 drives the support seat 524 on the connecting block 523 to move, thereby realizing the engagement and disengagement of the support seat 524 with the upper roller 3. This avoids the support seat 524 from blocking or interfering with the disassembly of the rolled insulating paper tube 6. The installation and disassembly of the support seat 524 are convenient and quick, which improves the efficiency of the rolling process of the board 6.

[0048] The guide groove 521 is raised and lowered by electric cylinder 527, and the support frame 51 is raised and lowered by electric cylinder 512, so that the two ends of the upper roller 3 are raised and lowered synchronously. The working height of the upper roller 3 is adjusted and limited by positioning nut 5281 and positioning nut 514, so that the height adjustment of the two ends of the upper roller 3 is more precise, which improves the rolling accuracy and efficiency of the sheet 6.

[0049] By setting the guide arc surface 5211, the connecting block 523 enters the guide groove 521 more smoothly. By setting the flared mouth 5242 inside the through hole 5241, the upper roller 3 enters the through hole 5241 more smoothly, thereby improving the reliability of the disengagement component 52 and making the rolling device run stably and reliably.

[0050] Technical features not described in detail in this solution are based on conventional operations and general understanding of those skilled in the art, and are therefore not elaborated upon here. Technical features not described in this utility model can be implemented using existing technology, and will not be repeated here.

Any changes, modifications, additions, or substitutions made by those skilled in the art within the scope of this utility model should also fall within the protection scope of this utility model.
