Description

Technical Field

[0001] The invention relates to the technical field of metal calendering, and in particular to a fully automatic metal foil calendering device. Background Art

[0002] Metal foil is a thin and tough metal material, usually made of metal (such as aluminum, copper, tin, etc.) through rolling, stretching or coating processes. It has excellent electrical conductivity, thermal conductivity and corrosion resistance. It is widely used in electronics, construction, packaging, printing and other fields. Metal foil can be made into foil paper, foil strips, foil sheets and other forms for various purposes. Calendering is a metal processing process that applies pressure to the metal material to deform it between a pair of rollers, thereby changing its shape and size. Calendering is usually used to process metal blanks into thin plates, foils, strips and other shapes. It can also be used to make metal bars, pipes, etc.

[0003] For example, the patent application with application publication number CN115921530A and application publication date April 7, 2023, and named "A Nonferrous Metal Rolling Processing Equipment", includes a base plate, and a shell is fixedly connected to the upper surface of the base plate; a non-ferrous metal block and a conveying mechanism, and the conveying mechanism is arranged above the base plate, and is used to first clamp the non-ferrous metal block and then convey it; a multi-angle cleaning component, a connecting component and a transmission component, and the connecting component is linked with the conveying mechanism, and drives the transmission component to operate, so that the multi-angle cleaning component cleans the upper and lower and sides of the non-ferrous metal block; an auxiliary structure, and the auxiliary structure is driven by the transmission component to spray hot air in the direction of the multi-angle cleaning component; a continuous rolling mechanism, and the continuous rolling mechanism is arranged inside the shell, and hammers the non-ferrous metal block before rolling.

[0004] The deficiency of the prior art is that the prior art generally directly performs calendering on the metal material, that is, the metal material directly enters between the two rollers of the calendering equipment for calendering. There is also a structure in which the metal material is hammered before calendering, as in the above-mentioned patent application. During the calendering process of the metal material, since the time the metal is squeezed between the rollers is limited, the thickness of the metal material after calendering is prone to uneven extension. When the metal material is hammered during the continuous calendering process, the surface of the metal material is easily scratched. Summary of the invention

[0005] The purpose of the present invention is to provide a fully automatic metal foil calendering device to solve the above-mentioned deficiencies in the prior art.

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a fully automatic metal foil rolling device, comprising a side plate, on which a plurality of groups of rollers are arranged, and also comprising: an extrusion assembly, which is rotatably arranged in the feeding area of ​​the plurality of groups of rollers, and when the extrusion assembly rotates, it can intermittently extrude the metal material to extrude its upper and lower surfaces into a wavy shape.

[0007] As mentioned above, the extrusion assembly includes two extrusion rollers, and two extrusion parts are arranged on the outer edges of the extrusion rollers. When the extrusion rollers rotate, the metal material can be intermittently extruded through the extrusion parts.

[0008] As mentioned above, the extrusion assembly also includes a cleaning plate, which is slidably arranged between the two side plates, and is used to clean the surface of the metal material.

[0009] As mentioned above, a rotating belt is provided on one side of the cleaning plate close to the squeezing roller, and the rotating belt is used to reduce the friction between the cleaning plate and the squeezing roller.

[0010] The above also includes a lubrication component, which is arranged above the roller close to the extrusion component, and the lubrication component can lubricate the rollers on both sides of the metal material during rolling.

[0011] As mentioned above, the lubrication assembly includes a truss, and two sliding blocks are arranged side by side on one side of the truss close to the roller. The truss is connected to the sliding blocks through a drainage pipe, and the drainage pipe is used to transport the lubricating medium to the sliding blocks to be coated on the surface of the roller.

[0012] As mentioned above, the lubrication assembly also includes an adjusting rod, both ends of which are respectively connected to the two sliding blocks, and the outer side of the adjusting rod is wrapped with sponge.

[0013] As mentioned above, two limiting rings are arranged on the outer side of each roller, and a plurality of inclined grooves are evenly arranged along the circumference of one end of each limiting ring close to each other near the extrusion assembly, and the lubricating medium can flow to the outer side of the roller on the lower side of the side plate through the inclined grooves of the limiting ring.

[0014] The above also includes a driving component, which is arranged at one end of the roller, and the driving component can simultaneously drive the extrusion component and multiple groups of the rollers to rotate simultaneously.

[0015] As mentioned above, the driving assembly includes a plurality of gears, and each of the extrusion rollers and one end of each of the rollers is provided with a gear, and the extrusion roller on the upper side of the side plate and one end of the plurality of rollers are also provided with latching teeth, and the latching teeth are connected by a synchronous belt, and one end of the extrusion roller on the upper side is connected to the output end of the rotating drive member.

[0016] In the above technical solution, the beneficial effect of the present invention is that: through the extrusion effect of the extrusion component on the metal material to be rolled, the extrusion component extrude both the upper and lower surfaces of the metal material to be rolled into a wavy shape, which can bring the following benefits:

[0017] First, the metal material extruded into a wavy shape is convenient for subsequent multiple sets of extrusion rollers to continuously roll it, ensuring that the metal material can be quickly formed;

[0018] Secondly, the metal material to be rolled is pre-treated by extrusion instead of hammering to avoid the situation where the hammering causes inconsistent depth of hammering pits on the metal material, which leads to surface defects after the metal is rolled;

[0019] Thirdly, the metal material is passively transferred during calendering only through the extrusion assembly and multiple groups of rollers, so that the metal material is extended evenly while avoiding scratches on the surface of the metal material. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0037] In the description of the present invention, it is to be understood that the terms "length", "width", "degree", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "inside", "outside", "axial", "radial", "circumferential" and the like indicating orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0038] like Figure 1-10 As shown, an embodiment of the present invention provides a fully automatic metal foil calendering device, comprising a side plate 1, on which a plurality of rollers 2 are arranged, and further comprising: an extrusion assembly 3, which is rotatably arranged in the feeding area of ​​the plurality of rollers 2, and when the extrusion assembly 3 rotates, it can intermittently extrude the metal material to extrude its upper and lower surfaces into a wavy shape. Specifically, calendering is a metal processing process that applies pressure to a metal sheet or plate so that it is deformed between one or more pairs of rollers 2 to change its shape and size. Calendering is generally used for The metal blank is processed into a shape of a thin plate, foil, strip, etc., and a plurality of groups of rollers 2 are arranged between the two side plates 1 in a rotating manner. The plurality of groups of rollers 2 include at least three groups, each group has two rollers 2, and the two rollers 2 are arranged up and down. According to the distance of the arrangement, the rollers 2 are named as the first roller 21, the second roller 22 and the third roller 23 in the direction from close to far from the extrusion assembly 3 (taking three groups of rollers 2 as an example), that is, the first roller 21 is closest to the extrusion assembly 3, and the distance between the two first rollers 21 is the largest. The distance between the two second rollers 22 is greater than the distance between the two third rollers 23, and so on, that is, the distance between the two first rollers 21, the two second rollers 22 and the two third rollers 23 gradually decreases, so that the first rollers 21, the second rollers 22 and the third rollers 23 gradually roll the metal material into a metal foil, and the extrusion assembly 3 is arranged at the front of the metal rolling feed, and the extrusion assembly 3 can intermittently extrude the metal material when it rotates. In this embodiment, the metal material first enters between the extrusion assemblies 3, so that the extrusion assembly 3 simultaneously extrudes the upper and lower surfaces of the metal material into a wavy shape when it rotates, and while the extrusion assembly 3 extrudes the metal material, the extrusion assembly 3 can also play a role in conveying the metal material. After the surface of the metal material is extruded into a wavy shape, it enters between the two first rollers 21, the two second rollers 22 and the two third rollers 23 in sequence, so that the multiple groups of rollers 2 gradually roll the metal material whose surface is extruded into a wavy shape into a metal foil.

[0039] An embodiment of the present invention provides a fully automatic metal foil calendering device, in which an extrusion component 3 extrude both the upper and lower surfaces of a metal material into a wavy shape. The metal material extruded into a wavy shape facilitates subsequent continuous calendering by multiple groups of rollers 2, thereby ensuring that the metal material can be quickly formed; the metal material to be calendered is pretreated by extrusion rather than hammering, thereby avoiding deep surface defects caused by hammering on the metal material; the metal material is passively conveyed by the extrusion component 3 and multiple groups of rollers 2 during calendering, thereby making the metal material evenly extended while avoiding scratches on the surface of the metal material.

[0040] In another embodiment provided by the present invention, the extrusion assembly 3 includes two extrusion rollers 31, two extrusion parts 311 are arranged on the outer edge of the extrusion roller 31, and the extrusion roller 31 can intermittently extrude the metal material through the extrusion part 311 when rotating. Specifically, two extrusion rollers 31 are arranged in a rotating manner between the two side plates 1, and the two extrusion rollers 31 are arranged up and down. The cross-section of each extrusion roller 31 is elliptical, and two extrusion parts 311 are symmetrically arranged on the outer side of the extrusion roller 31. The extrusion part 311 is also the position of the semi-major axis of the cross-section of the extrusion roller 31, and the outer surfaces of the two extrusion parts 311 are smooth The metal material is arc-shaped, so that after being squeezed, only continuous smooth waves will appear without step-shaped faults. Both surfaces of the metal material are squeezed and deformed into waves, that is, continuous peaks and troughs appear on the two surfaces of the metal material (peaks correspond to peaks, and troughs correspond to troughs). This facilitates the extrusion, and rolling the metal into a wave shape before rolling can bring the following benefits: 1. Improving uniformity: first, the metal is rolled into a wave shape by the two extrusion parts 311, and then rolled by the two first rollers 21. In fact, the two first rollers 21 roll the peaks and a small part of the troughs, so that The metal material at the crest is deformed and squeezed toward the trough, so that the metal material is quickly rolled and formed. The trough provides a deformation space to adapt to the movement and deformation of the metal material at the crest, avoiding excessive local deformation of the metal material during rolling, and making the metal obtain more uniform deformation in the subsequent rolling process. Second, reduce stress: when the wavy metal structure passes through the two first rollers 21 for rolling, the two first rollers 21 pull the entire metal material at the crest for transportation, and do not pull the metal material at the trough. At this time, the trough provides a buffer space to adjust the conveying rhythm of the metal material, reducing the metal material from being always in the state of being pulled. The state of pulling can reduce the stress concentration of metal materials during the rolling process, which is helpful to reduce the deformation resistance of metal materials and the deformation energy of metal materials. Third, improve the surface quality: the wavy metal structure can make the metal material at the crest move and deform to the trough, so as to avoid the situation that the metal material passes through the two first rollers 21 and the metal material is too thick after deformation (that is, when the metal material is deformed, the material at other positions is accumulated in the feeding area of ​​the two first rollers 21), which causes defects on the metal surface accumulated during the rolling of the metal material. This ensures that the metal surface is smoother, which is conducive to improving the surface quality and finish of metal products.Therefore, rolling the metal into a wavy shape before rolling can improve the efficiency and quality of metal processing and avoid surface defects during metal rolling. When the metal material enters between the two squeezing rollers 31, the two squeezing rollers 31 start to rotate, so that the two squeezing rollers 31 each drive the two squeezing parts 311 thereon to intermittently squeeze the upper and lower surfaces of the metal material, so that both surfaces of the metal material are squeezed and deformed into a wavy shape. The wavy metal material is convenient for the two first rollers 21, the two second rollers 22 and the two third rollers 23 to gradually roll it into a metal foil. ;

[0041] In another embodiment provided by the present invention, the extrusion assembly 3 further includes a cleaning plate 32, which is slidably arranged between the two side plates 1, and the cleaning plate 32 is used to clean the surface of the metal material. Specifically, the cleaning plate 32 is a vertical plate body with a rectangular groove in the middle, and brushes 321 are symmetrically arranged at the upper and lower positions of the rectangular groove in the middle of the cleaning plate 32, and the brushes 321 are arranged in a V shape, that is, the upper and lower sides of the rectangular groove in the middle of the cleaning plate 32 are parallel to the surface of the metal material, and the upper and lower sides of the rectangular groove parallel to the surface of the metal material are provided with V-shaped brushes 321, so that the brushes 321 can The cleaning plate 32 is capable of cleaning the upper and lower surfaces of the metal material. Two ear seats are respectively arranged on both sides of the cleaning plate 32. A circular hole is opened in the middle of each ear seat. Two sliding grooves are respectively arranged on the inner sides of the two side plates 1. A guide rod is fixedly arranged in each sliding groove. The ear seat is slidably arranged on the outside of the guide rod through the circular hole in the middle thereof. The ear seat is slidably arranged in the sliding groove. Each ear seat is connected to the side plate 1 through a buffer 322 such as a spring. The buffer 322 is sleeved on the outside of the guide rod, and the buffer 322 is arranged on the side of the ear seat away from the squeezing roller 31. One side of the cleaning plate 32 is connected to the two squeezing rollers 31. In this embodiment, during the pretreatment process of the metal material entering between the two squeezing rollers 31 to be squeezed into a wavy plate, granular impurities may be adhered to the two surfaces of the metal material. In this way, when the squeezing rollers 31 extrude the metal material, the sticky granular impurities may cause damage or surface defects to the surface of the metal material after being squeezed. To solve this problem, the squeezing rollers 31 rotate and extrude the metal material while squeezing the cleaning plate 32, so that the cleaning plate 32 drives the ear seat to move along the guide rod and the sliding groove. The guide rod and the sliding groove play a guiding and limiting role to prevent the cleaning plate 32 from deflecting and scratching the metal material. When the cleaning plate 32 squeezes the buffer 322 and drives the brush 321 to move, the upper and lower surfaces of the metal material are cleaned. At the same time, the V-shaped brush 321 is convenient for scraping impurities on the surface of the metal material, and the scraped impurities can be pushed from the middle of the metal material to both sides through the V-shaped brush 321, so that the impurities on the upper surface of the metal material can be directly discharged from the side of the metal surface (the impurities on the lower surface of the metal material are directly scraped off by the brush 321). The buffer 322 has a buffering and resetting effect on the cleaning plate 32, and ensures that the cleaning plate 32 is always in contact with the outer side of the squeezing roller 31.

[0042] Furthermore, the brush 321 is slidably arranged at the upper and lower positions of the rectangular groove in the middle of the cleaning plate 32 through a vertical rod 323, and a reset member 324 such as a spring is arranged between the vertical rod 323 and the cleaning plate 32, so that the reset member 324 can adjust the height of the brush 321 through the vertical rod 323, so that the brush 321 can clean the surface of metal materials of different thicknesses. In addition, the brush 321 can also clean the uneven surface of the same metal material to ensure the cleaning effect.

[0043] Furthermore, the brush 321 includes a fixed brush 3211 and multiple movable brushes 3212, that is, the V-shaped brush 321 consists of a fixed brush 3211 and multiple movable brushes 3212, the fixed brush 3211 is fixedly installed on the end of the vertical rod 323 away from the reset member 324, each of the movable brushes 3212 is set on the side of the fixed brush 3211 in a sliding manner, and a spring piece 3213 is set between the fixed brush 3211 and the multiple movable brushes 3212. In this way, when there are pits on the surface of the metal material, it is difficult for the brush 321 and the fixed brush 3211 to clean the inside of the pit. At this time, the movable brush 3212 is squeezed by the spring piece 3213, so that the movable brush 3212 slides along the fixed brush 3211, and the movable brush 3212 enters the inside of the pit for cleaning, thereby ensuring the cleaning effect of the brush 321.

[0044] In another embodiment provided by the present invention, a rotating belt 33 is provided on one side of the cleaning plate 32 close to the squeezing roller 31, and the rotating belt 33 is used to reduce the friction between the cleaning plate 32 and the squeezing roller 31. Specifically, a mounting groove is provided on one side of the cleaning plate 32 close to the squeezing roller 31, and a plurality of support shafts 325 are rotatably arranged in the mounting groove. The plurality of support shafts 325 are evenly arranged in the vertical direction, and a rotating belt 33 is commonly sleeved on the outer sides of the plurality of support shafts 325, so that the rotating belt 33 can rotate around the plurality of support shafts 325 in the mounting groove, and can slide relative to each other when the rotation speeds of the two do not match. The rotating belt 33 is a steel conveyor belt similar to a conveyor belt. The cleaning plate 32 is always in contact with the outer side of the squeezing roller 31 through the wear-resistant rubber on the rotating belt 33. In this embodiment, the squeezing roller 31 will squeeze the cleaning plate 32 while rotating to extrude the metal material. At this time, friction will occur between the squeezing roller 31 and the cleaning plate 32. The rotating belt 33 is provided to reduce the friction between the squeezing roller 31 and the cleaning plate 32, so that the squeezing roller 31 can slide on the cleaning plate 32 conveniently. The wear-resistant rubber on the surface of the rotating belt 33 can prevent the surface of the squeezing roller 31 from being damaged, thereby ensuring that the squeezing roller 31 will not cause damage or defects on the surface of the metal material when extruding the metal material.

[0045] In another embodiment provided by the present invention, a lubrication component 4 is further included. The lubrication component 4 is arranged above the roller 2 close to the extrusion component 3. The lubrication component 4 can lubricate the rollers 2 on both sides of the metal material during calendering. Specifically, the metal needs lubrication during the calendering process. The main purpose of lubrication is to reduce friction resistance, thereby reducing wear and extending the life of the roller 2. At the same time, lubrication can also improve the surface quality of the product. The lubrication component 4 is arranged above the first roller 21 located on the upper side. A lubricating medium such as mineral oil can be added to the lubrication component 4. The lubricating medium can flow out of the lubrication component 4 and fall through the two ends of the lubrication component 4 to the first roller 21 located on the lower side. In this embodiment, when the first roller 21 rotates to calender the metal material, the lubrication component 4 can lubricate the outer surface of the first roller 21, so that the first roller 21 transfers the lubricating medium to the surface of the metal material, so that the lubricating medium coats the surface of the metal material, so that the second roller 22 and the third roller 23 can also provide lubrication when calendering the metal material.

[0046] In another embodiment provided by the present invention, the lubrication assembly 4 includes a truss 41, and two sliding blocks 42 are arranged in parallel on one side of the truss 41 close to the roller 2. The truss 41 and the sliding block 42 are connected through a drainage pipe 43, and the drainage pipe 43 is used to transport the lubricating medium to the sliding block 42 to be coated on the surface of the roller 2. Specifically, the truss 41 is arranged between the two side plates 1, and a accommodating space is arranged inside the truss 41. The upper end of the accommodating space is provided with an addition port, which is sealed by a sealing bolt, and the lower side of the accommodating space is an inclined surface, and the two ends of the lower end of the accommodating space are respectively A leakage outlet is opened, and both leakage outlets are at the lowest point of the inclined surface. A slide groove is also provided in the truss 41, and the slide groove is below the accommodating space. The drainage tube 43 is provided in the slide groove. The sliding block 42 is rotatably arranged on the truss 41. A cavity structure is provided in the sliding block 42, and cotton is provided in the cavity structure. The sliding block 42 is provided with a plurality of through holes on both sides perpendicular to the length direction of the truss 41, and the through holes are connected to the cavity structure. The sliding block 42 is connected to the leakage outlet through the drainage tube 43, that is, the accommodating space of the truss 41 and the sliding block The cavity structures of the sliding block 42 are connected through the drainage tube 43. In this embodiment, the lubricating medium can be added to the accommodating space by unscrewing the sealing bolt. After the lubricating medium is added, the sealing bolt is screwed back. During the calendering process of the metal material, when the two extrusion rollers 31 rotate to extrude the metal material, the two first rollers 21 rotate synchronously. At this time, the lubricating oil in the accommodating space flows through the drainage tube 43 to the cavity structure in the sliding block 42, so that the cotton in the cavity structure is full of the lubricating medium. The outflow speed of the lubricating medium in the accommodating space can be controlled, and the lubricating medium can be passed through the multiple openings on the side of the sliding block 42. The liquid flows out through the through hole, thereby first dripping on the surface of the first roller 21 located above, and then dripping on the surface of the first roller 21 located below. When the metal material enters between the two first rollers 21 for rolling, the lubricating medium on the surfaces of the two first rollers 21 lubricates the metal material, thereby reducing wear, extending the life of the roller 2 and improving the surface quality of the product. In addition, the lubricating medium adheres to the surface of the metal material after passing through the pressing edges of the two first rollers 21, and the lubricating medium can continue to lubricate the metal material when entering between the second roller 22 and the third roller 23 for rolling.

[0047] Furthermore, a rubber layer 411 is provided at the middle of the upper end of the truss 41 (the middle of the upper end of the accommodating space), and a swing plate 412 is also rotatably provided between the two side plates 1, and the middle of the swing plate 412 is rotatably provided between the two side plates 1, one end of the swing plate 412 is provided above the rubber layer 411, and the other end of the swing plate 412 is provided at the upper end of the squeezing roller 31 located above, and the swing plate 412 includes an inclined section and a horizontal section, and a vertical section is further provided at the position of the horizontal section close to the truss 41, and the lower position of the junction of the inclined section and the horizontal section of the swing plate 412 (that is, the rotation center of the swing plate 412) is rotatably provided. The swing plate 412 is arranged between the side plates 1, and a baffle 413 is arranged below the rotation center of the swing plate 412. The baffle 413 is arranged between the two side plates 1. The baffle 413 is used to limit the swing plate 412. When the squeezing roller 31 located above rotates, the squeezing portion 311 can intermittently squeeze the end of the swing plate 412 close to the squeezing roller 31 (that is, the inclined section of the swing plate 412), so that the swing plate 412 intermittently squeezes the rubber layer 411 at one end close to the rubber layer 411 (that is, the vertical section of the swing plate 412), so that the rubber layer 411 reduces the accommodating space of the truss 41. The lubricating medium in the accommodating space can intermittently flow out to ensure the lubrication effect. The baffle plate 413 can limit the falling angle of the inclined section of the swing plate 412 after being squeezed, so as to avoid the swing plate 412 being misaligned with the squeezing portion 311 due to the large deflection angle and being difficult to be squeezed again by the squeezing portion 311. At the same time, the baffle plate 413 can also prevent the swing plate 412 from shaking after being squeezed once by the squeezing portion 311, causing the vertical section to squeeze the rubber layer 411 multiple times, thereby avoiding the waste of excessive outflow of lubricating medium. Furthermore, the addition port on the accommodating space is connected to the lubricating medium storage tank (not shown in the figure) through a pipeline. The first roller 21 is lubricated by the rubber layer 43. The first roller 21 is lubricated by the rubber layer 43. The first roller 21 is lubricated by the rubber layer 411. The first roller 21 is lubricated by the rubber layer 411. The lubricating medium in the storage tank is also passed through the pipeline into the storage space. The lubricating medium in the storage space is always sufficient to avoid lack of lubricating medium to the first roller 21. The metal material is always lubricated during the rolling process.

A sponge 45 is also arranged between the two sliding blocks 42, and the sponge 45 is arranged on the outside of the adjusting rod 44. In this embodiment, the two first rollers 21 roll the metal When the metal material is used, the lubricating oil in the accommodation space flows through the drainage pipe 43 to the cavity structure in the sliding block 42. At this time, the lubricating medium can flow out to the sponge 45 through the multiple through holes opened on the side of the sliding block 42, so that the sponge 45 coats the lubricating medium on the surface of the first roller 21 located above, and then the lubricating medium drips from the first roller 21 located above to the surface of the first roller 21 located below, and the distance between the two sliding blocks 42 is adjusted (that is, the positions of the two sliding blocks 42 on the truss 41 are adjusted) so that The two sliding blocks 42 respectively squeeze one end of the connecting rod 442 abutting thereon, so that the other ends of the two connecting rods 442 can simultaneously squeeze (or be squeezed by the elastic member 443) the elastic member 443 slides along the support rod 441 to adaptively change its length. At this time, the sponge 45 changes with the total length of the support rod 441 and the connecting rod 442 (that is, the length of the adjusting rod 44), ensuring that the sponge 45 can always evenly apply the lubricating medium to the surface of the first roller 21 located above.

[0049] Furthermore, another truss 41 is also provided below the first roller column 21 below the side panel 1, and two sliding blocks 42 are also provided on the truss 41 in a sliding manner, and the two sliding blocks 42 are also connected by the adjusting rod 44, and the outer side of the adjusting rod 44 is also wrapped with a sponge 45. The truss 41 and the sliding block 42 below the side panel 1 are basically the same in appearance as the truss 41 and the sliding block 42 above, except that the truss 41 below the side panel 1 has no accommodating space and sliding groove inside, and the sliding block 42 below the side panel 1 has no accommodating space and sliding groove inside. There is a cavity structure and a through hole, and the adjusting rod 44 and the sponge 45 located below the side plate 1 are exactly the same in shape and size as the adjusting rod 44 and the sponge 45 located below the side plate 1. In this way, after the lubricating medium drips from the first roller 21 above to the surface of the first roller 21 located below, the lubricating medium is evenly coated on the surface of the first roller 21 located below through the sponge 45 under the side plate 1. At the same time, the sponge 45 under the side plate 1 can also recover excess lubricating oil and continuously coat it on the surface of the first roller 21 located below the side plate 1.

Specifically, two limiting rings 24 are respectively arranged on the outer side of each of the rollers 2, and the outer diameter of each of the rollers 2 is the same as the inner diameter of the limiting ring 24 thereon, that is, the outer sides of the first roller 21, the second roller 22 and the third roller 23 are all provided with two limiting rings 24 in a sliding manner, and the total thickness of the two limiting rings 24 is the thickness of the metal material after rolling. The thickness of the metal material is controlled by the limit ring 24, so that the limit ring 24 controls the rolling thickness of each group of the rollers 2 to prevent the metal material from being over-rolled by the rollers 2 passing through the metal material (over-rolling means that when the metal material passes through the roller 2, the roller 2 squeezes the metal material and causes the metal material to deform too much, and the metal material may accumulate at a certain place, resulting in stress concentration in the metal material after rolling and surface defects on the surface of the metal material), which makes it difficult to roll the metal material between subsequent rollers 2. The limit ring 24 is provided with a locking bolt, and a rubber block is provided at one end of the locking bolt close to the inner wall of the limit ring 24, so that the locking bolt locks the limit ring 24 and fixes it in the When the roller 2 is on the outside, it is only squeezed and attached to the outer surface of the roller 2 by the rubber block to avoid the locking bolt from damaging the outer surface of the roller 2. The end of the limiting ring 24 on the two first rollers 21 that is close to each other is evenly provided with multiple inclined grooves 25 along its circumference. The inclined grooves 25 on the limiting ring 24 at the same end of the upper and lower first rollers 21 are in opposite directions, that is, the inclined grooves 25 on the limiting ring 24 at the same end of the upper and lower first rollers 21 can form a trumpet-shaped structure (the inclined grooves 25 on the limiting ring 24 at the same end of the upper and lower first rollers 21 are not strictly aligned and may be staggered). In this embodiment, the limiting ring 24 has two functions: first, By adjusting the distance between the two limiting rings 24 on the roller 2, the two limiting rings 24 control the width of the rolled metal material, thereby reducing the uneven edges of the metal material during rolling; secondly, the lubricating medium is drained to the surface of the first roller 21 located below through the inclined groove 25 on the limiting ring 24; when adjusting the distance between the two limiting rings 24, the limiting ring 24 will squeeze the elastic member 443 through the sliding block 42 and the connecting rod 442 to slide along the support rod 441, and the sponge 45 will change with the total length of the connecting rod 442 and the support rod 441, ensuring that the sponge 45 can always apply the lubricating medium to the surface of the first roller 21;Furthermore, two forming rollers (not shown in the figure) are arranged in the discharge area of ​​the plurality of rollers 2, and the two forming rollers are arranged between the two side plates 1 in a rotatable manner, and no limiting ring 24 is arranged on the outer side of the forming rollers, so as to ensure that the gap between the two forming rollers is minimized, so that the calendered metal foil can be pressed and formed between the two forming rollers. ;

The driving component 5 can simultaneously drive the extrusion component 3 and multiple groups of rollers 2 to rotate simultaneously. Specifically, the driving component 5 is arranged on the side of the side plate 1 away from the other side plate 1. During the rotation, it can simultaneously drive the two extrusion rollers 31, the two first rollers 21, the two second rollers 22 and the two third rollers 23 to rotate simultaneously, and make the rotation direction of the two extrusion rollers 31, the two first rollers 21, the two second rollers 22 and the two third rollers 23 able to extrude the metal material while passively conveying the metal material.

[0052] In another embodiment provided by the present invention, the driving assembly 5 includes a plurality of gears 51, each of the squeezing rollers 31 and one end of each of the rollers 2 is provided with a gear 51, and the squeezing rollers 31 on the upper side of the side plate 1 and one end of the plurality of rollers 2 are also provided with latch teeth, and the latch teeth are connected by a synchronous belt 52, and one end of the squeezing rollers 31 at the top is connected to a rotating driving member 53 such as an output end of a motor. Specifically, the gears 51 on each pair of rollers 2 are meshed with each other, and the squeezing rollers 31 at the top, the first roller 21, the second roller 22 and the third roller 23 are provided with latch teeth at the same end, and the squeezing rollers 31 at the top, the first roller 21, the second roller 22 and the third roller 23 are connected by the synchronous belt 52, that is, the squeezing rollers 31 at the top, the first roller 21, the second roller 22 and the third roller 23 can be driven simultaneously by the synchronous belt 52. When rotating, in this embodiment, when the metal material is calendered, the squeezing roller 31 connected to its output end is driven to rotate by the rotary driving member 53, so that the squeezing roller 31 located above drives the squeezing roller 31 located above to rotate synchronously through the gear 51, so that the two squeezing rollers 31 rotate and extrude the metal material entering the middle of the two into a wave shape. While the rotary driving member 53 drives the squeezing roller 31 connected to its output end to rotate, the latch teeth on the squeezing roller 31 drive the first roller 21, the second roller 22 and the third roller 23 located above to rotate through the synchronous belt 52. In this way, the first roller 21, the second roller 22 and the third roller 23 located below are driven to rotate synchronously through the gear 51, so that the two first rollers 21, the two second rollers 22 and the two third rollers 23 successively calender the passing metal material extruded into a wave shape into foil.

[0053] Preferably, a plurality of rotating shafts 11 are arranged between the extrusion roller 31 and the first roller 21, between the first roller 21 and the second roller 22, and between the second roller 22 and the third roller 23. The rotating shafts 11 are rotatably arranged between the two side plates 1, so that after the metal material is extruded and rolled, the metal material is supported and conveyed by the rotating shafts 11, thereby preventing the metal material from being unable to enter between the two first rollers 21, the two second rollers 22, and the two third rollers 23 due to gravity or extrusion deformation.
