Description

Technical Field

[0001] This utility model relates to the field of copper strip rolling technology, and in particular to a precision copper strip rolling device. Background Technology

[0002] During the rolling process of copper strip, dust and other impurity particles are easily adsorbed onto the surface of the roller under electrostatic adsorption. This causes impurity particles to penetrate into the surface or interior of the copper strip during rolling, resulting in dust and other impurities mixed in with the rolled copper strip, which affects its conductivity and urgently needs to be improved. Utility Model Content

[0003] The purpose of this invention is to provide a precision copper strip rolling device that can prevent dust particles from getting trapped in the copper strip during rolling, thus affecting the conductivity of the copper strip.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a precision copper strip rolling device, including a fixed frame, a fixed rolling assembly and a movable rolling assembly are provided on the fixed frame, the fixed rolling assembly is fixed to the bottom of the fixed frame, and the movable rolling assembly is raised and lowered on the fixed frame through a height adjustment mechanism. The fixed rolling assembly includes a lower drive module, a lower wrapping body and a lower roller provided at the output end of the lower drive module, and the movable rolling assembly includes an upper drive module, an upper wrapping body and an upper roller provided at the output end of the upper drive module. The lower roller is rotatably disposed in the lower enclosure, and the upper roller is rotatably disposed in the upper enclosure. Both the upper and lower enclosures are formed by two upper and lower half-covers fastened together. Each half-cover has a rotating groove corresponding to the upper or lower roller. A plurality of rolling blowing elements and rolling support elements are rotatably disposed on the inner wall of the rotating groove. The rolling support elements roll and cooperate with the outer wall of the upper or lower roller to form a support. Each rolling blowing element includes a blowing channel opened along the axial direction and a plurality of blowing holes that penetrate the outer wall of the rolling blowing element and communicate with the blowing channel. The outer wall of the rolling blowing element is in contact with the corresponding outer wall of the upper or lower roller. An air duct is provided inside the half-cover, and a negative ion generating module is detachably installed on the outer wall of the half-cover. The air inlet of the negative ion generating module is connected to an air compressor, and the air outlet of the negative ion generating module is connected to the purging channel through the air duct.

[0005] By adopting the above technical solution, the operator can adjust the height of the movable roller pressing assembly relative to the fixed roller pressing assembly using the height adjustment mechanism, thereby adjusting the roller pressing distance between the upper and lower rollers, and thus adjusting the rolling thickness of the copper strip. When the upper drive module and the lower drive module drive the corresponding upper roller and lower roller to rotate, the rolling support will rotate and cooperate with the outer wall of the corresponding upper or lower roller to form support. At the same time, the outer wall of the rolling blower contacts and rubs against the outer wall of the upper or lower roller to achieve rotation. The air compressor device passes compressed air into the negative ion generating module to generate negative ions. The air carrying negative ions enters the blowing channel of the rolling blower through the air passage and is finally sprayed out from the blowing hole of the rolling blower to blow the surface of the upper or lower roller, thereby removing static electricity and dust from the surface of the upper and lower rollers. This prevents dust and impurities from being rolled onto the copper strip and affecting its conductivity, thus having the effect of preventing dust particles from being trapped in the copper strip during rolling and affecting its conductivity.

[0006] A further feature of this invention is that the rolling purge member is rotatably disposed in the middle of the half-cover along the axial direction, and a plurality of the rolling support members are symmetrically arranged on both sides of the rolling purge member.

[0007] By adopting the above technical solution, the supporting force of the rolling support on both sides of the upper or lower roller is made more uniform.

[0008] A further feature of this invention is that the rolling blowing component is a bearing, and the half-cover has an axial mounting hole corresponding to the bearing, with the bearing being rotatably mounted in the corresponding mounting hole via a pin.

[0009] A further feature of this invention is that the rolling purging component includes an intermediate cylinder and rotating shafts symmetrically arranged at both ends of the intermediate cylinder along the axial direction. The purging channel is opened inside the intermediate cylinder, and an air passage is provided through the rotating shaft on the side near the air passage along the axial direction. The two ends of the air passage are respectively connected to the air passage and the purging channel.

[0010] A further feature of this invention is that the end face of the rotating shaft away from the intermediate cylinder is rotatably engaged with the half cover via a PTFE gasket. The half cover has an installation groove for installing the PTFE gasket. The PTFE gasket has a through hole in its center that connects the air passage and the air vent, and the end portion of the rotating shaft is inserted into the through hole.

[0011] By adopting the above technical solution, the PTFE gasket can effectively improve the smoothness of rotation between the end face of the rotating shaft and the half cover. At the same time, the PTFE gasket can also provide a certain degree of airtightness, which can ensure the airtightness between the end of the rotating shaft and the air passage to a certain extent. In addition, the PTFE gasket has good abrasion resistance and a longer service life.

[0012] A further feature of this invention is that: the half-cover has a hinge groove corresponding to the rotating shaft, the half-cover has a clearance groove corresponding to the intermediate cylinder, one end of the hinge groove is connected to the clearance groove, and the other end of the hinge groove is connected to the air passage through the mounting groove.

[0013] By adopting the above technical solution, the rolling purge component is partially hidden on the half-cover, which effectively reduces the risk of the rolling purge component detaching from the surface of the half-cover.

[0014] A further feature of this invention is that the outer wall of the half-cover has a receiving cavity, and the negative ion generating module is detachably installed in the receiving cavity by means of fasteners.

[0015] By adopting the above technical solution, the negative ion generating module can be detachably installed on the outer wall of the half-cover, which facilitates assembly and subsequent disassembly, cleaning or replacement.

[0016] A further feature of this invention is that a rubber layer is bonded to the outside of the rolling blower, and the rubber layer has an air jet hole that communicates with the blower hole.

[0017] By adopting the above technical solution, the rubber layer can effectively improve the friction between the rolling blower and the outer wall of the upper or lower roller, which is conducive to the upper or lower roller driving the rolling blower to rotate smoothly.

[0018] A further feature of this invention is that the height adjustment mechanism includes a drive motor, a transmission assembly, a first lifting rod, and a second lifting rod. The bottoms of the first and second lifting rods are connected to the upper end of the upper wrapping body. The drive motor can drive the first and second lifting rods to move up and down through the transmission assembly, and drive the movable roller pressing assembly to move relatively closer to or away from the fixed roller pressing assembly.

[0019] A further feature of this invention is that a buffer spring is provided between the bottom of the upper wrapping body and the top of the lower wrapping body.

[0020] By adopting the above technical solution, the buffer spring can effectively prevent damage caused by rigid collision when the moving roller assembly is close to the fixed roller assembly.

[0021] In summary, this utility model has the following beneficial effects: A rolling blower and a rolling support are rotatably mounted on the semi-enclosed parts of the movable and fixed roller pressing assemblies. The operator can adjust the height of the movable roller pressing assembly relative to the fixed roller pressing assembly using a height adjustment mechanism, thereby adjusting the roller pressing gap between the upper and lower rollers and consequently the rolling thickness of the copper strip. When the upper and lower drive modules drive the corresponding upper and lower rollers to rotate, the rolling support rotates and engages with the outer wall of the corresponding upper or lower roller to form support. Simultaneously, the outer wall of the rolling blower contacts the upper roller... The rotation is achieved through contact friction between the outer wall of the lower roller and the upper roller. The air compressor introduces compressed air into the negative ion generating module to generate negative ions. The air carrying negative ions enters the blowing channel of the rolling blowing component through the air passage and is finally ejected from the blowing hole of the rolling blowing component to blow the surface of the upper or lower roller, thereby removing static electricity and dust from the surface of the upper and lower rollers. This prevents dust and impurities from being rolled onto the copper strip and affecting its conductivity. It has the effect of preventing dust particles from being trapped in the copper strip during rolling and affecting its conductivity. Attached Figure Description

[0030] The present invention will be further described below with reference to the accompanying drawings.

[0031] A precision copper strip rolling apparatus, such as Figures 1-7As shown, the device includes a fixed frame 1, on which a fixed roller pressing assembly 2 and a movable roller pressing assembly 3 are mounted. The fixed roller pressing assembly 2 is fixed to the bottom of the fixed frame 1, and the movable roller pressing assembly 3 is slidably connected to the fixed frame 1 via a guide rail structure 11. The movable roller pressing assembly 3 is raised and lowered on the fixed frame 1 via a height adjustment mechanism 5.

The movable roller pressing assembly 3 includes an upper drive module 31, an upper wrapping body 33, and an upper roller 32 located at the output end of the upper drive module 31. The lower roller 22 is rotatably mounted in the lower wrapping body 23, and the upper roller 32 is rotatably mounted in the upper wrapping body 33. Both the upper wrapping body 33 and the lower wrapping body 23 are formed by two upper and lower half-covers 4 fastened together. The lower half-cover 4 of the upper wrapping body 33 and the upper half-cover 4 of the lower wrapping body 23 have openings in the middle that connect with the upper roller. The upper roller 32 and the lower roller 22 have a clearance space for mutual avoidance. The half-cover 4 is provided with a rotating groove 401 corresponding to the upper roller 32 or the lower roller 22. Several rolling blowing parts 42 and rolling support parts 43 are rotatably provided on the inner wall of the rotating groove 401. The rolling support parts 43 roll and cooperate with the outer wall of the upper roller 32 or the lower roller 22 to form support. The rolling blowing parts 42 include a blowing channel 4211 opened along the axial direction and several blowing holes 4212 that penetrate the outer wall of the rolling blowing parts 42 and communicate with the blowing channel 4211. The outer wall of the rolling blowing parts 42 is in partial contact with the outer wall of the corresponding upper roller 32 or the lower roller 22. An air passage 44 is opened inside the half-cover 4. A negative ion generating module 45 is detachably installed on the outer wall of the half-cover 4. The air inlet end of the negative ion generating module 45 is connected to an air compressor device 46. The air outlet end of the negative ion generating module 45 is connected to the blowing channel 4211 through the air passage 44.

[0032] like Figures 6-7 As shown, the rolling blower 42 is rotatably disposed in the middle of the half cover 4 along the axial direction, and several rolling support members 43 are symmetrically arranged on both sides of the rolling blower 42, so that the supporting force of the rolling support members 43 on both sides of the upper roller 32 or the lower roller 22 is more uniform; the rolling blower 42 is set as a bearing, and the half cover 4 has a mounting hole 41 corresponding to the bearing along the axial direction, and the bearing is rotatably disposed in the corresponding mounting hole 41 by means of a pin.

[0033] like Figures 3-7As shown, the rolling purging component 42 includes an intermediate cylinder 421 and rotating shaft portions 422 symmetrically arranged at both ends of the intermediate cylinder 421 along the axial direction. A purging channel 4211 is opened inside the intermediate cylinder 421, and an air passage 4221 is opened through the rotating shaft portion 422 on the side near the air passage 44 along the axial direction. The two ends of the air passage 4221 are connected to the air passage 44 and the purging channel 4211, respectively. The end face of the rotating shaft portion 422 away from the intermediate cylinder 421 is rotatably engaged with the half cover 4 by a PTFE gasket 47. The half cover 4 has a mounting groove 405 for installing the PTFE gasket 47. The PTFE gasket 47 has a through hole 471 in the center that connects the air passage 44 and the air passage 4221, and the end portion of the rotating shaft portion 422 is inserted into the through hole 471. The PTFE gasket 47 can effectively improve the rotational smoothness between the end face of the rotating shaft portion 422 and the half cover 4. 7 can also provide a certain degree of airtightness, which to a certain extent ensures the airtightness between the end of the rotating shaft 422 and the air passage 44. In addition, the PTFE gasket 47 has good abrasion resistance and a longer service life. The half cover 4 has a hinge groove 402 corresponding to the rotating shaft 422 and a clearance groove 403 corresponding to the intermediate cylinder 421. One end of the hinge groove 402 is connected to the clearance groove 403, and the other end of the hinge groove 402 is connected to the air passage 44 through the mounting groove 405. The half cover 4 has a hinge groove 402 corresponding to the rotating shaft 422 and a clearance groove 403 corresponding to the intermediate cylinder 421. One end of the hinge groove 402 is connected to the clearance groove 403, and the other end of the hinge groove 402 is connected to the air passage 44 through the mounting groove 405, so that the rolling purge component 42 is partially hidden on the half cover 4, which effectively reduces the risk of the rolling purge component 42 detaching from the surface of the half cover 4.

[0034] like Figures 1-5As shown, a receiving cavity 404 is provided on the outer wall of the half-cover 4. The negative ion generating module 45 is detachably installed in the receiving cavity 404 by fasteners, so that the negative ion generating module 45 can be detachably installed on the outer wall of the half-cover 4, which is convenient for assembly and subsequent disassembly, cleaning or replacement. A rubber layer 48 is bonded to the outside of the rolling blowing component 42. The rubber layer 48 has a jet hole 481 communicating with the blowing hole 4212. The rubber layer 48 can effectively increase the friction between the rolling blowing component 42 and the outer wall of the upper roller 32 or the lower roller 22, which is conducive to the upper roller 32 or the lower roller 22 driving the rolling blowing component 42 to rotate smoothly. The height adjustment mechanism 5 includes a drive motor 51 and a transmission component 52. The first lifting rod 53 and the second lifting rod 54, the transmission assembly 52 are existing technologies, are worm gear structures, and adjacent worm gears are connected by a linkage shaft.

The drive motor 51 can drive the first lifting rod 53 and the second lifting rod 54 to move up and down through the transmission assembly 52, and drive the movable roller pressing assembly 3 to move closer to or away from the fixed roller pressing assembly 2. A buffer spring 6 is provided between the bottom of the upper wrapping body 33 and the top of the lower wrapping body 23. The buffer spring 6 can effectively prevent the movable roller pressing assembly 3 from being damaged by rigid collision when it is close to the fixed roller pressing assembly 2.

[0035] The basic working principle of this utility model is as follows: A rolling blower 42 and a rolling support 43 are rotatably mounted on the half-cover 4 of the movable roller pressing assembly 3 and the fixed roller pressing assembly 2. The operator can adjust the height of the movable roller pressing assembly 3 relative to the fixed roller pressing assembly 2 using the height adjustment mechanism 5, thereby adjusting the roller pressing distance between the upper roller 32 and the lower roller 22, and thus adjusting the roller pressing thickness of the copper strip. When the upper drive module 31 and the lower drive module 21 drive the corresponding upper roller 32 and lower roller to rotate, the rolling support 43 will rotate and cooperate with the outer wall of the corresponding upper roller 32 or lower roller 22 to form support. At the same time, the rolling blower 42... Rotation is achieved through contact and friction between the outer wall of the upper roller 32 or the outer wall of the lower roller 22. The air compressor introduces compressed air into the negative ion generating module 45 to generate negative ions. The air carrying negative ions enters the blowing channel 4211 of the rolling blowing component 42 through the air passage 44, and is finally ejected from the blowing hole 4212 of the rolling blowing component 42 to blow and sweep the surface of the upper roller 32 or the lower roller 22, thereby removing static electricity and dust from the surface of the upper roller 32 and the lower roller 22. This prevents dust and impurities from being rolled onto the copper strip and affecting its conductivity. It has the effect of preventing dust particles from being trapped in the copper strip during rolling and affecting its conductivity.
