Description

Technical Field

[0001] The invention relates to the technical field of metal coil calendering, and in particular to a non-ferrous metal coil calendering machine. Background Art

[0002] Nonferrous metals, in a narrow sense, are also called non-ferrous metals, which are a general term for all metals other than iron, manganese and chromium. Nonferrous metals in a broad sense also include nonferrous alloys; as the demand for nonferrous metals increases, their processing machinery is also constantly being invented; when processing flat metal materials, the metal materials need to be rolled, and the production of nonferrous metal coils often requires the cooperation of a rolling machine.

[0003] Existing nonferrous metal coils are calendered by upper and lower calendering wheels. If the motor of one of the calendering wheels fails due to short circuit or other reasons, in order to avoid greater losses, this calendering wheel will stop rotating urgently, while the other calendering wheel will calender one side of the metal coil while continuing to rotate, resulting in uneven thickness of the calendered coil, with one side being thinner and the other side being thicker, further causing the metal coil to be unusable after calendering on one side, increasing production costs. Therefore, the present invention designs a nonferrous metal coil calender to solve the above problems. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a non-ferrous metal coil calender, comprising a shell, an upper calendering device is fixedly connected to the inner wall of the shell, an upper calendering wheel is rotatably connected to the inner wall of the upper calendering device, a lower calendering mechanism is arranged below the upper calendering wheel, and a protective mechanism is fixedly connected to the outer surface of the lower calendering mechanism; the upper calendering device can control the rotation of the upper calendering wheel and cooperate with the lower calendering mechanism to calender the metal coil, and the protective mechanism can ensure that when one of the calendering devices stops rotating, the other calendering device stops rotating, thereby avoiding unilateral calendering of the metal coil, which would cause the subsequent metal coil to be unusable.

[0005] The protective mechanism includes a lower calendering wheel, the outer surface of which is fixedly connected to a fixing ring, the outer surface of which is slidably connected to a slide plate, both sides of which are slidably connected to fixed boxes, the side of which is away from the fixing ring is fixedly connected to an extrusion spring, the end of which is away from the slide plate is fixedly connected to a receiving plate, the side of which is close to the extrusion spring is fixedly connected to a limiting tube, the inner wall of which is slidably connected to a sliding rod, and a pressure sensor is provided inside the fixed box. The fixing ring will contact the slide plate during rotation and push the slide plate to slide along the inner wall of the fixed box. The pressure sensor senses the pressure to determine whether the upper and lower calendering devices have stopped rotating.

[0006] Furthermore, the outer surface of the lower calendering mechanism is fixedly connected to the inner wall of the shell, the side of the fixed box close to the shell is fixedly connected to the inner wall of the shell, the outer surface of the receiving plate is fixedly connected to the inner wall of the fixed box, and the end of the sliding rod close to the slide plate is fixedly connected to the side of the slide plate close to the limiting tube.

[0007] Furthermore, the lower calendering mechanism includes a motor, the output shaft of the motor is fixedly connected to a fixed disk, the end of the fixed disk away from the motor output shaft is fixedly connected to a bending rod, and the side of the bending rod away from the fixed disk is fixedly connected to a rotating device. The motor can drive the fixed disk to rotate, and the bending rod is used to drive the rotating device to rotate.

[0008] Furthermore, a bracket is fixedly connected at the center of the outer surface of the rotating device, a connecting tube is slidably connected to the inner wall of the rotating device, an arc groove is provided on the outer surface of the connecting tube, and transport components are fixedly connected to both sides of the rotating device. The bracket provides support for the rotation of the rotating device, and the rotating device can drive the rotation of the connecting tube during rotation, and can drive the subsequent transport components to operate synchronously.

[0009] Furthermore, the outer surface of the motor is fixedly connected to the inner wall of the shell, the side of the bracket away from the rotating device is fixedly connected to the inner wall of the shell, the side of the connecting tube away from the bending rod is fixedly connected to the outer surface of the lower rolling wheel, and the inner walls on both sides of the connecting tube are rotatably connected to the outer surfaces on both sides of the rotating device.

[0010] Furthermore, the transport component includes a right gear, the right gear is meshed with a toothed chain, the toothed chain is meshed with a left gear on the side away from the right gear, the inner wall of the gear is fixedly connected with an emergency stop component, the inner wall of the emergency stop component is slidably connected with a clamping cylinder, the clamping cylinder is fixedly connected with a transport wheel on the side close to the toothed chain, a fixing frame is provided below the clamping cylinder, and both sides of the fixing frame are fixedly connected with a limiting axis. The synchronous movement of the transport component and the rotating device is achieved by the coordinated rotation of the right gear and the toothed chain. The purpose of providing multiple transport wheels is to facilitate the transportation of metal coils and replace manual labor. At the same time, transport wheels are provided on the upper and lower sides of the metal coils, which can limit the upper and lower sides of the coils and ensure that the coils can accurately enter the calendering port between the two calendering wheels.

[0011] Furthermore, the inner wall of the right gear is fixedly connected to the outer surface of the rotating device, the side of the fixing frame away from the emergency stop component is fixedly connected to the inner wall of the shell, and the upper surface of the limit shaft is slidably connected to the lower surface of the tooth chain.

[0012] Furthermore, the emergency stop component includes an emergency stop cylinder, the inner wall of the emergency stop cylinder is provided with a slide groove, the inner wall of the slide groove is fixedly connected to a right electromagnet, the inner wall of the slide groove is fixedly connected to a stop shaft, and the outer surface of the stop shaft is rotatably connected to a right magnetic plate. During the rotation of the emergency stop cylinder, the right magnetic plate is in contact with the slide groove, and during the contact process, the rotation of the emergency stop cylinder is driven. There are multiple slide grooves to facilitate the pushing of the right magnetic plate. The function of the stop shaft is to facilitate the rotation of the right magnetic plate.

[0013] Furthermore, the inner wall of the emergency stop cylinder is slidably connected to the inner wall of the locking cylinder, the center of the outer surface of the emergency stop cylinder is fixedly connected to the inner wall of the fixing frame, and the outer surface of the right magnetic plate is slidably connected to the outer surface of the emergency stop cylinder.

[0014] The beneficial effects of the present invention are as follows:

[0015] 1. The device cooperates with the sliding of the slide plate through the rotation of the fixed ring, so that the pressure sensor can detect the extrusion force generated by the fixed ring on the slide plate and the slide bar, and judge whether the calendering wheel is continuing to rotate. When one calendering wheel stops rotating, the pressure sensor cannot detect the signal and will control the remaining calendering device to stop rotating, so as to avoid the situation that after one calendering wheel is emergency braked, the other calendering wheel continues to rotate, resulting in the metal coil being only unilaterally calendered, resulting in uneven thickness, and further causing the coil after unilateral calendering to be unusable.

[0016] 2. The device is equipped with multiple transport wheels above and below the metal coil, which can replace manual transportation and positioning of the metal coil. The metal coil is relatively soft, which can avoid the problem that when a long metal coil is held manually, the front end of the coil bends downward, making it difficult to align with the gap between the two calendering wheels and carry out subsequent calendering.

[0017] 3. The device realizes the synchronous rotation of the calendering wheel and multiple transport wheels by setting the rotating device and the transport parts. When one of the calendering wheels stops rotating due to emergency braking, multiple transport wheels can be quickly stopped to avoid the situation where the transport mechanism is still transporting, causing the excess coils to be rolled up due to the stopped calendering wheel, resulting in the accumulation of excess coils in front of the gap between the two calendering wheels, further causing the problem that the coils cannot be calendered.

[0018] 4. When one of the calendering wheels stops rotating, the device can quickly extract the metal coil from between the two calendering wheels and between the multiple transport wheels and put it into the intact machine for re-calendering. The setting of the notch on the surface of the right magnetic plate and the clamping cylinder and the setting of the connecting cylinder and the surface arc groove can prevent the calendering wheel and the transport wheel from clamping the coil due to the meshing of the gear and the chain during the coil extraction process, which makes it difficult to extract the metal coil and further affects the subsequent coil calendering efficiency.

DETAILED DESCRIPTION

[0030] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0031] For example, see Figure 1-Figure 7 The present invention provides a technical solution: a non-ferrous metal coil calender, comprising a shell 1, an upper calendering device 2 is fixedly connected to the inner wall of the shell 1, an upper calendering wheel 3 is rotatably connected to the inner wall of the upper calendering device 2, a lower calendering mechanism 4 is arranged below the upper calendering wheel 3, and a protective mechanism 5 is fixedly connected to the outer surface of the lower calendering mechanism 4; the upper calendering device 2 can control the rotation of the upper calendering wheel 3, and cooperate with the lower calendering mechanism 4 to calender the metal coil, and the protective mechanism 5 can ensure that the other calendering device stops rotating when one of the calendering devices stops rotating, so as to avoid the metal coil being unilaterally calendered, resulting in the problem that the subsequent metal coil cannot be used.

[0032] The protection mechanism 5 includes a lower calendering wheel 51, a fixing ring 52 is fixedly connected to the outer surface of the lower calendering wheel 51, a slide plate 53 is slidably connected to the outer surface of the fixing ring 52, a fixing box 54 is slidably connected to both sides of the slide plate 53, a pressing spring 55 is fixedly connected to the side of the slide plate 53 away from the fixing ring 52, a receiving plate 56 is fixedly connected to the end of the pressing spring 55 away from the slide plate 53, a limiting tube 57 is fixedly connected to the side of the receiving plate 56 close to the pressing spring 55, a sliding rod 58 is slidably connected to the inner wall of the limiting tube 57, and a pressure sensor 59 is arranged inside the fixing box 54. The fixing ring 52 will contact the slide plate 53 during rotation and push the slide plate 53 to slide along the inner wall of the fixing box 54. The pressure sensor 59 senses the pressure to determine whether the upper and lower calendering devices have stopped rotating.

[0033] When in use, when the whole device is calendering the metal coil, the metal coil is calendered by the synchronous rotation of the upper calendering wheel 3 and the lower calendering wheel 51, and the upper calendering device 2 can control the rotation of the upper calendering wheel 3, and the lower calendering mechanism 4 can drive the lower calendering wheel 51 to rotate. When one of the motors 41 is short-circuited or otherwise fails, the calendering process driven by this motor 41 will stop rotating, and if the other calendering wheel continues to rotate, it will cause the coil to be unilaterally calendered, making it unusable in the future. The protection mechanism 5 can transmit a signal to another intact calendering device to control it to stop rotating.

[0034] The outer surface of the lower calendering mechanism 4 is fixedly connected to the inner wall of the shell 1, the side of the fixed box 54 close to the shell 1 is fixedly connected to the inner wall of the shell 1, the outer surface of the receiving plate 56 is fixedly connected to the inner wall of the fixed box 54, and the end of the sliding rod 58 close to the slide plate 53 is fixedly connected to the side of the slide plate 53 close to the limiting tube 57.

[0035] The lower calendering mechanism 4 includes a motor 41, the output shaft of the motor 41 is fixedly connected to a fixed disk 42, one end of the fixed disk 42 away from the output shaft of the motor 41 is fixedly connected to a bending rod 43, and the side of the bending rod 43 away from the fixed disk 42 is fixedly connected to a rotating device 44. The motor 41 can drive the fixed disk 42 to rotate, and the bending rod 43 is used to drive the rotating device 44 to rotate.

[0036] A bracket 45 is fixedly connected to the center of the outer surface of the rotating device 44, a connecting tube 46 is movably connected to the inner wall of the rotating device 44, an arc groove 47 is provided on the outer surface of the connecting tube 46, and a transport component 48 is fixedly connected to both sides of the rotating device 44. The bracket 45 provides support for the rotation of the rotating device 44, and the rotating device 44 can drive the rotation of the connecting tube 46 during the rotation, and can drive the subsequent transport component 48 to run synchronously.

[0037] The outer surface of the motor 41 is fixedly connected to the inner wall of the shell 1, the side of the bracket 45 away from the rotating device 44 is fixedly connected to the inner wall of the shell 1, the side of the connecting tube 46 away from the bending rod 43 is fixedly connected to the outer surface of the lower rolling wheel 51, and the inner walls on both sides of the connecting tube 46 are rotatably connected to the outer surfaces on both sides of the rotating device 44.

[0038] When in use, when the upper calendering wheel 3 and the lower calendering wheel 51 are needed to calender the coil, the motor 41 can be started to drive the fixed plate 42 and the bending rod 43 to rotate through the output shaft, and the bending rod 43 can drive the rotation of the rotating device 44 during the rotation process, and the rotation of the rotating device 44 can drive the rotation of the connecting tube 46 during the rotation process. The bracket 45 provides support for the rotation of the rotating device 44, and the connecting tube 46 can drive the rotation of the lower calendering wheel 51, and cooperate with the rotation of the upper calendering wheel 3 to calender the metal coil. The rotating device 44 can also drive the rotation of the transport component 48 when it rotates.

[0039] The upper calendering device 2 and a part of the lower calendering mechanism 4 are symmetrically arranged, except that the upper control motor 41 is located on the left side, and the lower control motor 41 is located on the right side. During the rotation of the upper and lower calendering wheels, the outer surfaces of both sides of the upper and lower calendering wheels are provided with fixed rings 52, so the fixed rings 52 will also rotate with the rotation of the calendering wheels. The fixed rings 52 will contact the slide plate 53 during the rotation. The two sides of the slide plate 53 are arranged as inclined surfaces, so the slide plate 53 can be pushed to slide inward along the inner wall of the fixed box 54. During the sliding process, the slide plate 53 can drive the movement of the slide bar 58, and the slide bar 58 slides along the inner wall of the limit tube 57, and the slide plate 53 slides toward the pressure sensor 59. The sliding rod 58 approaches the pressure sensor 59 during the sliding process and finally squeezes the pressure sensor 59. Therefore, each time the sliding rod 58 squeezes the pressure sensor 59, it indicates that the fixed ring 52 and the calendering wheel are rotating. When one calendering wheel stops rotating, the pressure sensor 59 cannot detect the pressure signal and transmits the signal to the external controller to control the remaining calendering device to stop rotating, so as to avoid the calendering wheel continuing to rotate, resulting in the metal coil being only unilaterally calendered and being unusable later.

[0040] For example 2, please refer to Figure 1-Figure 10 The present invention provides a technical solution: on the basis of the first embodiment, the transport component 48 comprises a right gear 481, the right gear 481 is meshedly connected with a toothed chain 482, the toothed chain 482 is meshedly connected with a left gear 483 on the side away from the right gear 481, the inner wall of the left gear 483 is fixedly connected with an emergency stop component 484, the inner wall of the emergency stop component 484 is slidably connected with a clamping cylinder 485, the clamping cylinder 485 is fixedly connected with a transport wheel 486 on the side close to the toothed chain 482, a fixing frame 487 is arranged below the clamping cylinder 485, and both sides of the fixing frame 487 are fixedly connected with a limiting shaft 488. The synchronous movement of the transport component 48 and the rotating device 44 is realized by the coordinated rotation of the right gear 481 and the toothed chain 482, and the function of providing a plurality of transport wheels 486 is to facilitate the transportation of metal coils and replace manual labor, and at the same time, the upper and lower sides of the metal coils are provided with transport wheels 486, which can limit the upper and lower sides of the coils and ensure that the coils can accurately enter the calendering port between the two calendering wheels.

[0041] The inner wall of the right gear 481 is fixedly connected to the outer surface of the rotating device 44 , the side of the fixing frame 487 away from the emergency stop component 484 is fixedly connected to the inner wall of the shell 1 , and the upper surface of the limiting shaft 488 is slidably connected to the lower surface of the toothed chain 482 .

[0042] The emergency stop component 484 includes an emergency stop cylinder 4841, a slide groove 4842 is provided on the inner wall of the emergency stop cylinder 4841, a right electromagnet 4843 is fixedly connected to the inner wall of the slide groove 4842, a stop shaft 4844 is fixedly connected to the inner wall of the slide groove 4842, and a right magnetic plate 4845 is rotatably connected to the outer surface of the stop shaft 4844. During the rotation of the emergency stop cylinder 4841, the right magnetic plate 4845 is in contact with the slide groove 4842, and during the contact process, the rotation of the emergency stop cylinder 4841 is driven. There are multiple slide grooves 4842, which facilitate the pushing of the right magnetic plate 4845. The function of the stop shaft 4844 is to facilitate the rotation of the right magnetic plate 4845.

[0043] The inner wall of the emergency stop cylinder 4841 is slidably connected to the inner wall of the locking cylinder 485 , the center of the outer surface of the emergency stop cylinder 4841 is fixedly connected to the inner wall of the fixing frame 487 , and the outer surface of the right magnetic plate 4845 is slidably connected to the outer surface of the emergency stop cylinder 4841 .

[0044] When in use, the rotating device 44 can drive the right gear 481 and the toothed chain 482 to rotate during the rotation process, and the toothed chain 482 meshes and rotates with the left gear 483 during the rotation process, that is, the toothed chain 482 can drive the left gear 483 to continue to rotate, and can also drive the rotation of the emergency stop component 484. By connecting the movement of the upper calendering device 2 with the movement of the transport component 48, when the upper calendering device 2 stops moving, the transport component 48 can also stop running. The fixed frame 487 supports and limits the rotation of the emergency stop cylinder 4841. The limiting shaft 488 is arranged below the toothed chain 482 to provide support and limit for the rotation of the toothed chain 482, so as to avoid the toothed chain 482 being too loose below and the meshing effect with the gear being unsatisfactory.

[0045] The emergency stop component 484 can drive the rotation of the locking cylinder 485 during the rotation process, and further drive the rotation of the transport wheel 486. Multiple transport wheels 486 are arranged on the upper and lower sides of the metal coil, which can replace manual transportation of the metal coil, and provide limiting and supporting functions for the transportation of the metal coil, to avoid the problem that the front end of the longer metal coil is soft and bent when it is taken, which makes it difficult to align with the gap between the two calendering wheels and carry out subsequent calendering.

[0046] The left gear 483 can drive the emergency stop cylinder 4841 to rotate during its rotation. A plurality of small slide grooves 4842 are arranged inside the emergency stop cylinder 4841, and a right electromagnet 4843 is fixed thereto. When the motor 41 rotates to drive the entire device to operate, the right electromagnet 4843 is energized and operates. The transport wheel 486 inside the lower calendering mechanism 4 and the left gear 483 rotate clockwise to drive the coil to be transported. When the right electromagnet 4843 is energized, it will adsorb the right magnetic plate 4845 and tightly contact the inner wall of the emergency stop cylinder 4841. During its rotation, the right magnetic plate 4845 can contact the transverse groove inside the locking cylinder 485 and drive the locking cylinder 485 to rotate, thereby realizing the rotation of the transport wheel 486.

[0047] When the entire calendering device stops rotating in an emergency, part of the metal coil has been calendered, while the other part has not been calendered and needs to be further calendered. If the inspection and maintenance time is too long, the coil will be left between multiple transport wheels 486 and the upper and lower calendering wheels, resulting in reduced coil calendering efficiency.

[0048] When the coil is stuck between the multiple transport wheels 486 and the two calendering wheels, the entire motor 41 stops rotating, and the right electromagnet 4843 loses power, that is, it no longer attracts the right magnetic plate 4845, and the right magnetic plate 4845 also loses the ability to drive the clamping cylinder 485. The user artificially draws the uncalendered coil outward away from the outer side of the calendering device, and the coil causes the transport wheel 486 and the two calendering wheels to rotate during the extraction process, and the lower transport wheel 486 and the lower calendering wheel 51 rotate counterclockwise, that is, the transport wheel 486 drives the clamping cylinder 485 to rotate counterclockwise, and the clamping cylinder 485 touches the right magnetic plate 4845 during the counterclockwise rotation, and pushes the right magnetic plate 4845 to rotate around the outer surface of the stop shaft 4844, and fits into the inner wall of the emergency stop cylinder 4841, which will not affect the rotation of the emergency stop cylinder 4841. That is, when the coil is pulled out, the transport component 48 will only drive the transport wheel 486 and the locking cylinder 485 to rotate, and the lower calendering mechanism 4 will only drive the lower calendering wheel 51 and the connecting cylinder 46 to rotate, but will not drive the movement of the rotating device 44. The metal coil can be taken out more easily without causing the meshing force between the tooth chain 482 and the rack in the rotating device 44 to make it difficult to take out. After the coil is taken out, it is convenient to put the metal coil into another normally working machine for further calendering processing.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention.
