Description

Technical Field

[0001] The invention relates to the technical field of spiral duct machines, and in particular to an adjustable automatic feeding device for the production and processing of spiral duct machines. Background Art

[0002] The spiral duct machine is a device used to wind wide coils into spiral pipes. Its working principle is to input the raw materials into the bite machine through the driving mechanism and the transmission mechanism. The bite machine curls the two sides of the coil upward and downward respectively, and then uses the guiding effect of the circular steel belt to make the downward curled edge and the upward curled edge interlock with each other. Finally, the interlocking wheels that roll up and down relatively apply pressure to the interlocking curled edges to form a spiral duct. In the prior art, when producing and processing spiral ducts, an automatic feeding device is required to transfer the duct raw materials to the processing port for welding the duct raw materials. However, in common automatic feeding devices, the distance between the clamping wheels for the duct raw materials remains unchanged, resulting in the inability to transfer thicker duct raw materials to the feed port through clamping. At the same time, it is unable to clamp thinner duct raw materials, and thus is unable to transfer thinner duct raw materials. Therefore, the existing automatic feeding device cannot automatically adjust the distance between the clamping wheels according to the thickness of the duct raw materials, thereby affecting the feeding of the duct raw materials.

[0026] The transmission mechanism includes an adjustment component arranged on one side of the top of the turntable 2. By setting the adjustment component, it is convenient to adjust the distance between the transmission rollers 13, so as to adapt to strip steels of different thicknesses, which is conducive to stable loading. The adjustment component includes a rotating plate 7, and the rotating plate 7 can rotate. The upper and lower sides of the rotating plate 7 are respectively rotatably connected to the first connecting block 8 and the second connecting block 9 through a transmission plate 45. The rotating plate 7 is rotatably connected to the first connecting block 8 and the second connecting block 9 through the rotation cooperation of the pin shaft and the transmission plate 45. Connecting rods 10 are arranged on both sides of the rotating plate 7. The two ends of the first connecting block 8 are slidably sleeved on the connecting rod 10. The connecting rod 10 is connected to the first connecting block 8. The connecting block 8 is limited, and the second connecting block 9 is fixedly sleeved on both sides of the top of the connecting rod 10. The bottom end of the connecting rod 10 is fixedly connected to the connecting plate 11. The connecting rod 10 is used for transmission between the second connecting block 9 and the connecting plate 11. A clamping frame 12 is arranged between the connecting plate 11 and the first connecting block 8. A transmission roller 13 is rotatably installed in the clamping frame 12.

The bottom of the limiting frame 14 is fixedly connected to the bottom plate 1, and the limiting frame 14 limits the support of the connecting rod 10.

[0027] By placing the strip steel coil on one side of the turntable 2, the inner support rod 5 is driven to move by the rotation of the adjustment disk 4, so that the inner support rod 5 approaches the inner ring surface of the coil until the inner support rod 5 abuts against the inner ring surface of the coil, thereby fixing and supporting the coil, and then supporting the turntable 2 through the fixed frame 3. At this time, the initial end of the strip steel coil is extended into the clamping frame 12, so that the transmission roller 13 drives the coil to move, thereby driving the coil to move in the direction close to the clamping frame 12, and then driving the rotation of the turntable 2, so that the coil can be transported from the coil fixing mechanism to the inside of the transmission mechanism, and the transmission roller 13 is supported by the clamping frame 12, so that the strip steel and the transmission roller 13 slide through each other.

When it is necessary to clamp and convey the duct raw materials of different thicknesses, the rotating plate 7 is screwed to make the rotating plate 7 connected with the first connecting block 8 and the second connecting block 9 through rotation, so that the first connecting block 8 and the second connecting block 9 can move toward or away from each other, and then the first connecting block 8 can indirectly drive the upper clamping frame 12 to move, and the second connecting block 9 can indirectly drive the lower clamping frame 12 to move through the connection between the connecting rod 10 and the connecting plate 11, so as to adjust the distance between the two clamping frames 12 to adapt to material rolls of different thicknesses. In addition, under the setting of the buffer assembly, the transmission roller 13 can be further made close to the strip steel, thereby improving the stability of feeding.

[0028] Embodiment 2: On the basis of embodiment 1, a T-shaped shaft 15 is fixedly connected to one side of the turntable 2, and the T-shaped shaft 15 is rotatably sleeved on the top of the fixed frame 3. The rotation stability of the turntable 2 is improved by the rotational connection between the T-shaped shaft 15 and the fixed frame 3. The bottom of the fixed frame 3 is fixedly connected to the bottom plate 1, and the bottom plate 1 supports the fixed frame 3. A large limit sleeve 16 is fixedly connected to the other side of the turntable 2. The large limit sleeve 16 is rotatably connected to one end of the limit shaft 17. An annular groove is provided in the large limit sleeve 16, and a limit ring is fixedly sleeved on the limit shaft 17. The annular groove and the limit shaft 17 are rotatably connected, thereby improving the large limit The sleeve 16 ensures the stability of the limit position of the limit shaft 17. The other end of the limit shaft 17 is fixedly connected to the adjusting disk 4, so as to facilitate the rotation of the adjusting disk 4. A sliding hole 18 is provided on the surface of the adjusting disk 4. The sliding hole 18 is slidably connected to the inner support rod 5. The sliding hole 18 limits the inner support rod 5. The inner support rod 5 is fixedly sleeved on one end of the connecting sleeve rod 19 near the turntable 2. The other end of the connecting sleeve rod 19 is rotatably sleeved on the limit pin 20. The limit pin 20 is fixedly installed on the turntable 2. The edge position of the surface of the turntable 2 is fixedly connected to the limit arc plate 21 in a circular array. The setting of the limit arc plate 21 can prevent the air duct material from loosening.

[0029] The outer ring surface of the adjusting disk 4 is fixedly sleeved with a gear ring 22, and a gear 23 is meshed on one side of the gear ring 22. The gear 23 and the gear ring 22 are meshed for transmission. The gear 23 is fixedly sleeved on one end of the rotating shaft 24, and the other end of the rotating shaft 24 is rotatably sleeved on the rotating disk 2. A small limiting hole 25 is opened on the surface of the gear 23, and the rotating shaft 24 is rotatably sleeved in the small limiting sleeve 26. The small limiting sleeve 26 limits the rotating shaft 24. One end of the small limiting sleeve 26 is fixedly connected to the rotating disk 2, and the other end of the small limiting sleeve 26 abuts against the adjusting ring 27. The adjusting ring 27 is fixedly sleeved on the rotating shaft 2 4, the rotating shaft 24 is driven to rotate by twisting the adjusting ring 27, a cavity 28 is opened inside the small limiting sleeve 26, a pressing piece 29 is slidably installed in the cavity 28, a small spring 30 is fixedly installed between the pressing piece 29 and the cavity 28, one end of the small spring 30 is fixedly connected to one side of the pressing piece 29, and the other end of the small spring 30 is fixedly connected to the inner wall of the cavity 28 close to the turntable 2, one side of the outer ring surface of the pressing piece 29 is fixedly connected to one end of the steel rod 31, and the other end of the steel rod 31 is fixedly connected to the pin 32, and the pin 32 is slidably plugged into the small limiting hole 25.

[0030] When it is necessary to place the duct material roll, the inner ring surface of the material roll is sleeved on the outside of the inner support rod 5, and its outer ring surface is inside the limiting arc plate 21. At this time, the steel rod 31 is pulled in the direction close to the turntable 2, so that the steel rod 31 drives the pin 32 to slide out of the small limiting hole 25, and then the adjusting ring 27 is twisted. The adjusting ring 27 drives the rotating shaft 24 to rotate under the limitation of the small limiting sleeve 26, and the rotating shaft 24 then drives the gear 23 to rotate, and the gear 23 is meshed with the gear ring 22, so that the gear ring 22 drives the adjusting disk 4 to move. The adjusting disk 4 rotates under the rotation connection between the limiting shaft 17 and the large limiting sleeve 16, and the inner support rod 5 is driven to move through the arc-shaped sliding hole 18 opened on the surface of the adjusting disk 4. The inner support rod 5 then drives the connecting sleeve rod 19 to rotate under the limit of the limit pin 20, so that the inner support rod 5 moves toward the inner ring surface of the material roll until the anti-slip rubber sleeve 6 on the outer ring surface of the inner support rod 5 is tightly abutted against the inner ring surface of the material roll. At this time, stop twisting the adjusting ring 27, and then loosen the steel rod 31. Under the reverse elastic force of the small spring 30, the pressing plate 29 drives the pin 32 to be reinserted into the small limit hole 25 opened on the gear 23, thereby avoiding the rotation of the gear 23 and improving the stability of the material roll placement. Through the setting of the adjusting ring 27, the user can place hollow duct materials of different sizes between the inner support rod 5 and the limit arc plate 21, which expands the scope of use and improves the practicality of the entire device.

The bottom of the multi-stage electric cylinder 33 is fixedly connected to the base plate 1, and the base plate 1 stably supports the multi-stage electric cylinder 33. The driving roller device 34 on the top of the multi-stage electric cylinder 33 is fixedly installed. The driving roller device 34 is a prior art, that is, a transmission belt or chain is driven by a motor, and the transmission is driven by the meshing action of a pulley or a sprocket, thereby driving the roller to rotate. A through hole is provided on the clamping frame 12 arranged on the lower side, and the through hole is provided to facilitate the insertion of the rotating roller of the driving roller device 34. Two limit frames 14 are provided and are arranged symmetrically about the central plane of the clamping frame 12.

One end of the large spring 40 is fixedly connected to the limiting block 42, and the other end of the large spring 40 is fixedly connected to the bottom wall of the limiting groove 41. Both ends of the transmission roller 13 are rotatably sleeved in the limiting block 42, and the lower surface of the first connecting block 8 and the upper surface of the connecting plate 11 are welded and fixed to the clamping frame 12 through a T-shaped frame 43.

[0032] When the installation of the duct raw material coil is completed, the initial end of the strip steel coil is extended into the clamping frame 12, and the multi-stage electric cylinder 33 is controlled to drive the driving roller device 34 to move, so that the driving roller device 34 is close to the bottom of the lower clamping frame 12 until its rotating roller is extended into the lower clamping frame 12, so that the rotation of the rotating roller and the rotation of the output transmission roller 13 drive the material coil to move, thereby driving the material coil to move in the direction close to the clamping frame 12, and then driving the rotation of the turntable 2, so that the material coil can be transported from the material coil fixing mechanism to the inside of the transmission mechanism, and then to the processing port. When the strip enters the clamping frame 12, it will contact the rotating roller and the transmission roller 13. The limit block 42 and the limit groove 41 slide together, and then the large spring 40 is elastically connected to make the transmission roller 13 fit together, thereby improving the stability during the loading process. When it is necessary to load and transmit raw materials of different thicknesses, the hand wheel disc 38 is rotated to drive the rotating plate 7 to rotate through the connection of the connecting shaft 44. The rotating plate 7 is then rotated between the first connecting block 8 and the second connecting block 9 through the rotation cooperation of the pin shaft and the transmission plate 45, so that the first connecting block 8 and the second connecting block 9 can be connected.

When the first connecting block 8 and the second connecting block 9 move back to back, the first connecting block 8 drives the upper clamping frame 12 to move downward through the connection of the T-shaped frame 43 The second connecting block 9 is fixedly connected with the connecting rod 10, so that the connecting rod 10 drives the connecting plate 11 to move upward, and the connecting plate 11 drives the lower clamping frame 12 to move upward through the connection of the T-frame 43, thereby realizing the relative movement of the two clamping frames 12, so as to adapt to the air duct materials of different thicknesses, thereby avoiding that the air duct materials of different thicknesses cannot be clamped by the transmission roller 13, and the air duct materials cannot be fed. After the adjustment is completed, the locking screw 37 is sleeved in the large limit hole 39 and threadedly connected with the threaded hole 36, so as to lock the hand wheel 38, thereby completing the adjustment of the required thickness.
