Description

Technical Field

[0001] This invention relates to the field of steel strip processing technology, specifically to a continuous rolling composite molding equipment for coating steel strip substrates. Background Technology

[0002] Steel strip coating typically involves continuously feeding the film onto the surface of the steel strip substrate, and then bonding the film to the substrate through pressing, rolling, or other methods to form a continuous coating layer on the steel strip surface. Existing steel strip coating equipment usually includes a film feeding mechanism, a steel strip conveying mechanism, and a film pressing mechanism. During the continuous conveying of the steel strip, the film is guided to the surface and rolled by pressure rollers to bond the film to the steel strip substrate.

[0003] During continuous lamination, the steel belt needs to be stably transported along a preset direction, while the membrane material needs to maintain a relatively accurate positional relationship with the steel belt. When the width of the steel belt changes, the existing equipment's guiding and pressing structures usually need to be adjusted accordingly; otherwise, the steel belt may easily shift laterally during transport, or the lamination positions between the membrane material and the steel belt may not correspond, leading to problems such as inconsistent lamination width and membrane edge misalignment. Furthermore, when both the upper and lower surfaces of the steel belt need to be laminated, the lamination process typically requires separate processing on each surface. Continuous processing places high demands on the spatial arrangement of the equipment and the stability of the steel belt's transport.

[0004] Furthermore, the membrane material needs to maintain a stable pressing state during continuous conveying. However, steel strips of different thicknesses and specifications require different pressing positions and gaps when passing through the pressing area. In existing pressing structures, the pressing position is usually relatively fixed. When the steel strip specifications or membrane material condition change, the relative position between the pressing roller and the steel strip is not easily adjusted, which can easily lead to insufficient or excessive pressing, affecting the composite quality between the membrane material and the steel strip. For steel strips that have already been coated, if a further pressing process is lacking, there may still be localized insufficient adhesion between the membrane material and the steel strip.

[0005] On the other hand, membrane materials are usually supplied continuously in roll form, and the roll rotates continuously as the membrane material is pulled during the lamination process. As the membrane material is continuously output, the amount of membrane material on the roll gradually decreases and eventually runs out. However, existing continuous lamination equipment often cannot determine in time whether the roll is in a state without membrane material. If the equipment continues to operate after the membrane material is exhausted, the steel belt may continue to be transported in a state without membrane material, causing the continuous lamination process to be interrupted and affecting the continuity of the production process. Summary of the Invention

[0006] To address the aforementioned issues, a continuous roll-forming composite molding device for steel strip substrate lamination is provided. By proposing a device that can automatically guide, stably convey, and roll-form the steel strip substrate and the film material, the technical problems of film material misalignment, wrinkles, and insufficient composite bonding stability during continuous lamination are solved.

[0007] To address the problems of existing technologies, this invention provides a continuous roll forming equipment for coating steel strip substrates, comprising: a frame; a guide module disposed on the frame for guiding the steel strip along a preset direction; the guide module includes a first guide frame, a left limiting frame and a right limiting frame slidably disposed on the first guide frame, and a pressurizing unit disposed at the rear end of the frame, wherein the left limiting frame and the right limiting frame form a guide channel for the steel strip to pass through; an upper coating module fixedly disposed on the frame and located above the guide module for coating the upper surface of the steel strip; and a lower coating module. The upper and lower coating modules are positioned below the guide module and are used to coat the lower surface of the steel strip with film. The pressurizing unit includes a fixed guide roller and a movable guide roller that are positioned horizontally across the frame. The movable guide roller is position-adjustable relative to the fixed guide roller. A movable guide gap is formed between the fixed and movable guide rollers to allow the coated steel strip to pass through, and this gap is used for secondary rolling of the coated steel strip. The upper and lower coating modules respectively transport the film strip to the upper and lower surfaces of the steel strip and connect the film strip to the steel strip through rolling.

[0008] Preferably, the upper film coating module includes an upper film pressing unit, a first fixing frame fixedly disposed on the top of the upper film pressing unit, and a first film roll rotatably disposed on the first fixing frame; the upper film pressing unit is provided with a lifting frame and a first film pressing roller vertically disposed on the lower surface of the lifting frame, and a second film pressing roller and a third film pressing roller are also fixedly disposed on the lower surface of the lifting frame at opposite ends of the rear side of the first film pressing roller; the first film pressing roller, the second film pressing roller and the third film pressing roller are slidably connected to a slide rail fixedly disposed on the lower surface of the lifting frame through a connecting frame, so that the second film pressing roller and the third film pressing roller can be adjusted in position along the slide rail.

[0009] Preferably, the axial length of the first pressing roller is less than the width of the film strip, and the second pressing roller and the third pressing roller are located on both sides of the first pressing roller and can move towards or away from each other along the slide rail to change the pressing range between the second pressing roller and the third pressing roller, so as to adapt to steel strips of different widths for film coating.

[0010] Preferably, the lifting frame is vertically mounted on the machine frame via a second guide frame. A second electric push rod is vertically mounted on the second guide frame, and the driving end of the second electric push rod is connected to the lifting frame to drive the lifting frame to move up and down along the second guide frame. When the second electric push rod drives the lifting frame to descend, it drives the first pressing roller, the second pressing roller, and the third pressing roller to approach the upper surface of the steel belt to roll and coat the film belt in the conveying state.

[0011] Preferably, the lower film coating module includes a second fixed frame, a second film roll rotatably mounted on the second fixed frame, and a lower film pressing unit transversely mounted on the frame. The second film roll and the first film roll are arranged vertically opposite each other. The lower film pressing unit is provided with a fourth film pressing roller that can longitudinally approach or move away from the lower surface of the steel strip, and third guide frames that are arranged opposite to both ends of the fourth film pressing roller. The fourth film pressing roller is transversely mounted on the frame through the third guide frames at both ends and is located below the steel strip to roll and laminate the film strip on the lower surface of the steel strip.

[0012] Preferably, the first guide frame is provided with an adjustment block that can drive the fourth pressing roller to adjust its position in the vertical direction and a locking member that can lock the adjusted fourth pressing roller, so as to change the pressing height of the fourth pressing roller by adjusting the distance between the fourth pressing roller and the lower surface of the steel strip, and to self-lock the fourth pressing roller by the locking member after the adjustment is completed.

[0013] Preferably, the left limiting frame and the right limiting frame in the guiding module can be adjusted laterally relative to the first guiding frame to change the width of the guiding channel; the movable guiding roller in the pressurizing unit can be adjusted relative to the fixed guiding roller to change the width of the movable guiding gap, so that coated steel strips of different thicknesses are subjected to corresponding secondary rolling pressure when passing through the movable guiding gap.

[0014] Preferably, the device further includes a membrane material detection module, which includes a detector and a receiver. Two detectors are provided, each tilted and fixedly mounted on one side of the first and second fixing frames. Two receivers are provided, each sleeved and installed at the end of the first and second membrane rolls. When the first and second membrane rolls rotate, they respectively drive the corresponding receivers to rotate, so that the receivers periodically pass through the detection area of ​​the corresponding detector. When the membrane strip on the first or second membrane roll is continuously pulled and conveyed, the corresponding membrane roll remains in a rotating state, and the detector continuously detects the corresponding receiver. When the membrane strip on the corresponding membrane roll is exhausted, the membrane roll stops rotating, so that the detector cannot detect the receiver within a preset time, thereby determining that the membrane strip on the corresponding membrane roll is exhausted and issuing a membrane replacement prompt.

[0015] The advantages of this invention compared to the prior art are: 1. This invention sets up an upper film coating module and a lower film coating module located on opposite sides of a steel belt, so that the upper and lower film belts can be transported from both sides of the steel belt and synchronously rolled and laminated by each pressure roller. This allows the steel belt to be double-sided coated during continuous transmission, thereby reducing processing interruptions caused by repeated clamping or flipping of the steel belt and improving continuous coating capability.

[0016] 2. This invention adapts the steel strip conveying position using horizontally adjustable left and right limit frames, and coordinates with a second and third pressure roller that can adjust the pressure range, and a fourth pressure roller that can adjust the pressure height. This allows the guide width, coating range, and upper and lower pressure positions to be adjusted according to different specifications of steel strips. At the same time, the fixed and movable guide rollers are used to perform secondary rolling on the coated steel strip, thereby improving the guiding stability and film-strip composite stability of steel strips of different specifications during continuous coating.

[0017] 3. The present invention sets up detectors and receivers corresponding to the first and second film rolls respectively, so that the rotation state of the film roll can reflect the continuous feeding state of the film belt; when the film belt is exhausted and the film roll stops rotating, the detector can determine that the film material is exhausted and issue a film replacement prompt if the corresponding receiver cannot be detected within a preset time, thereby enabling timely detection of abnormal film material supply and reducing the interruption of continuous coating caused by the exhaustion of film material.

[0027] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0028] See Figures 1 to 8As shown: A continuous roll forming equipment for coating steel strip substrate includes: a frame 1; a guide module 2, disposed on the frame 1, for guiding the steel strip along a preset direction; the guide module 2 is provided with a first guide frame 21, a left limiting frame 22 and a right limiting frame 23 slidably disposed on the first guide frame 21, and a pressurizing unit 24 disposed at the rear end of the frame 1, the left limiting frame 22 and the right limiting frame 23 forming a guide channel for the steel strip to pass through; an upper coating module 3, fixedly disposed on the frame 1 and located above the guide module 2, for coating the upper surface of the steel strip; and a lower coating module 4, relative to the frame 1. The upper coating module 3 is located below the guide module 2 and is used to coat the lower surface of the steel strip with film. The pressurizing unit 24 is provided with a fixed guide roller 241 and a movable guide roller 242 that are arranged across the frame 1. The movable guide roller 242 can be adjusted in position relative to the fixed guide roller 241. A movable guide gap is formed between the fixed guide roller 241 and the movable guide roller 242 for the coated steel strip to pass through, which is used to perform secondary rolling on the coated steel strip. The upper coating module 3 and the lower coating module 4 respectively transport the film strip to the upper and lower surfaces of the steel strip, and combine the film strip with the steel strip by rolling.

[0029] When continuous coating processing of the steel strip substrate is required, the steel strip is first introduced into the guide module 2, so that the steel strip is conducted along the extension direction of the first guide frame 21. The left limiting frame 22 and the right limiting frame 23 limit the lateral position of the steel strip, so that the steel strip can be stably conveyed forward along the guide channel. Subsequently, the film strips are led out by the upper coating module 3 and the lower coating module 4 respectively, so that the upper film strip is attached to the upper surface of the steel strip and the lower film strip is attached to the lower surface of the steel strip. During the continuous transmission of the steel strip, it is rolled by the upper coating module 3 and the lower coating module 4 respectively, so that the upper and lower film strips are continuously laminated with the steel strip substrate.

[0030] As the coated steel strip continues to be conveyed to the rear end of the frame 1, it enters the movable guide gap between the fixed guide roller 241 and the movable guide roller 242 of the pressurizing unit 24. By adjusting the position of the movable guide roller 242 relative to the fixed guide roller 241, the coated steel strip is rolled again when passing through the movable guide gap, thereby further promoting the adhesion between the film strip and the steel strip surface and keeping the coated steel strip stable.

[0031] Through the cooperation of the guiding module 2, the upper coating module 3, the lower coating module 4 and the pressurizing unit 24, the steel strip can complete the synchronous coating of the upper and lower surfaces and subsequent secondary rolling during continuous transmission, reducing the lateral displacement of the steel strip and the insufficient adhesion between the film and the steel strip during the coating process, thereby improving the composite stability of the steel strip after continuous coating.

[0032] See Figure 5 As shown: The upper film coating module 3 includes an upper film pressing unit 31, a first fixing frame 32 fixedly disposed on the top of the upper film pressing unit 31, and a first film roll 33 rotatably disposed on the first fixing frame 32; the upper film pressing unit 31 is provided with a lifting frame 311 and a first film pressing roller 312 vertically disposed on the lower surface of the lifting frame 311, and a second film pressing roller 313 and a third film pressing roller 314 located at the rear ends of the first film pressing roller 312 are also fixedly disposed on the lower surface of the lifting frame 311; the first film pressing roller 312, the second film pressing roller 313 and the third film pressing roller 314 are slidably connected to a slide rail 316 fixedly disposed on the lower surface of the lifting frame 311 through a connecting frame 315, so that the second film pressing roller 313 and the third film pressing roller 314 can be adjusted in position along the slide rail 316.

[0033] When it is necessary to coat the upper surface of the steel strip, the film strip on the first film roll 33 is first guided to be output towards the upper pressing unit 31. After the film strip passes through the area where the first pressing roller 312, the second pressing roller 313 and the third pressing roller 314 are located, the film strip is rolled by each pressing roller during the continuous transmission of the steel strip, so that the film strip gradually adheres to the upper surface of the steel strip.

[0034] The first pressing roller 312, the second pressing roller 313, and the third pressing roller 314 are slidably connected to the slide rail 316 via connecting frames 315, thus allowing the position of each pressing roller to be adjusted according to the film-coating position of the steel strip and the actual coverage area of ​​the film strip. When it is necessary to change the relative position between the fourth pressing rollers 431, the corresponding connecting frame 315 is moved along the slide rail 316, thereby changing the pressing position of each fourth pressing roller 431, so that the film strip can contact and roll against the upper surface of the steel strip along a predetermined path.

[0035] By combining the above-mentioned film belt feeding structure with the structure of multiple fourth pressure rollers 431, the film belt can be continuously rolled during continuous conveying, and the position of the fourth pressure rollers 431 can be adjusted according to the coating needs, thereby improving the adaptability and stability of the upper surface coating process.

[0036] See Figure 3As shown: the axial length of the first pressing roller 312 is less than the width of the film strip. The second pressing roller 313 and the third pressing roller 314 are located on both sides of the first pressing roller 312 and can move towards or away from each other along the slide rail 316 to change the pressing range between the second pressing roller 313 and the third pressing roller 314, so as to adapt to steel strips of different widths for film coating.

[0037] When it is necessary to coat steel strips of different widths, the positions of the second pressure roller 313 and the third pressure roller 314 are adjusted according to the actual width of the steel strip. Since the axial length of the first pressure roller 312 is less than the width of the film strip, the second pressure roller 313 and the third pressure roller 314 can be located on both sides of the first pressure roller 312 and move towards or away from each other along the slide rail 316.

[0038] When the width of the steel strip changes, the distance between the second pressing roller 313 and the third pressing roller 314 is changed so that multiple fourth pressing rollers 431 form a pressing range corresponding to the current width of the steel strip. During the continuous conveying of the steel strip, the film strip passes through the adjusted pressing area and is subjected to corresponding rolling pressure so that the film strip can cover the surface of the steel strip of the corresponding width.

[0039] Therefore, without replacing the entire upper film pressing unit 31, the film pressing range can be changed simply by adjusting the positions of the second film pressing roller 313 and the third film pressing roller 314, so that the same filming equipment can adapt to continuous filming processing of steel strips of different widths.

[0040] See Figure 5 As shown: The lifting frame 311 is vertically mounted on the machine frame 1 via the second guide frame 317. A second electric push rod 318 is vertically mounted on the second guide frame 317. The driving end of the second electric push rod 318 is connected to the lifting frame 311 to drive the lifting frame 311 to move up and down along the second guide frame 317. When the second electric push rod 318 drives the lifting frame 311 to descend, it drives the first pressing roller 312, the second pressing roller 313 and the third pressing roller 314 to approach the upper surface of the steel belt to roll and coat the film belt in the conveying state.

[0041] When it is necessary to adjust the pressing distance between the upper film-coating module 3 and the steel strip, the second electric push rod 318 first drives the lifting frame 311 to move vertically along the second guide frame 317. When the second electric push rod 318 drives the lifting frame 311 to move downward, the first pressing roller 312, the second pressing roller 313 and the third pressing roller 314, which are fixed to the lower surface of the lifting frame 311, simultaneously approach the upper surface of the steel strip.

[0042] After each of the fourth pressure rollers 431 moves to the predetermined pressure position, the film belt enters between the steel belt and each of the fourth pressure rollers 431. As the steel belt is transported in a preset direction, the fourth pressure rollers 431 roll the film belt, causing it to gradually adhere to the upper surface of the steel belt. When it is necessary to stop the film coating process or adjust the pressure position, the second electric push rod 318 can be used to drive the lifting frame 311 upward, moving each of the fourth pressure rollers 431 away from the steel belt.

[0043] The second guide frame 317 guides the movement direction of the lifting frame 311, and the second electric push rod 318 drives the lifting frame 311, so that multiple fourth pressing rollers 431 can be raised and lowered synchronously, thereby facilitating the adjustment of the relative position between the upper pressing unit 31 and the steel belt.

[0044] See Figure 8 As shown: The lower film coating module 4 includes a second fixing frame 41, a second film roll 42 rotatably mounted on the second fixing frame 41, and a lower film pressing unit 43 transversely mounted on the frame 1. The second film roll 42 and the first film roll 33 are arranged vertically opposite each other. The lower film pressing unit 43 is provided with a fourth film pressing roller 431 that can longitudinally approach or move away from the lower surface of the steel strip, and a third guide frame 432 that is arranged opposite to both ends of the fourth film pressing roller 431. The fourth film pressing roller 431 is transversely mounted on the frame 1 through the third guide frame 432 at both ends and is located below the steel strip to roll and laminate the film strip on the lower surface of the steel strip.

[0045] When it is necessary to coat the lower surface of the steel strip, the film strip on the second film roll 42 is guided to be conveyed towards the lower pressing unit 43. Since the second film roll 42 is located below the first film roll 33, it can provide film material for coating the lower surface of the steel strip. When the film strip passes through the fourth pressing roller 431, as the steel strip is continuously conveyed in a preset direction, the fourth pressing roller 431 rolls the film strip from below the steel strip, thereby making the film strip adhere to the lower surface of the steel strip.

[0046] The fourth pressing roller 431 is transversely mounted on the frame 1 via the third guide frames 432 at both ends, so that the fourth pressing roller 431 can laterally cover the film strip on the lower surface of the steel strip, and the third guide frames 432 maintain the relative position between the fourth pressing roller 431 and the steel strip.

[0047] With the upper coating module 3 and the lower coating module 4 respectively set on the upper and lower sides of the steel strip, the coating of the upper and lower surfaces of the steel strip can be completed in one continuous transmission process, avoiding the need to process the two surfaces of the steel strip independently.

[0048] See Figure 7 and Figure 8As shown: The first guide frame 21 is provided with an adjustment block 433 that can drive the fourth pressing roller 431 to adjust its position in the vertical direction and a locking member 434 that can lock the adjusted fourth pressing roller 431. This is used to change the pressing height of the fourth pressing roller 431 by adjusting the distance between the fourth pressing roller 431 and the lower surface of the steel strip, and to self-lock the fourth pressing roller 431 by the locking member 434 after the adjustment is completed.

[0049] When it is necessary to adjust the pressing height of the fourth pressing roller 431 according to the thickness of the steel strip or the coating state of the lower surface, the adjusting block 433 set on the first guide frame 21 is operated first to make the fourth pressing roller 431 move closer to or away from the lower surface of the steel strip in the vertical direction, thereby changing the relative distance between the fourth pressing roller 431 and the steel strip.

[0050] After the fourth pressing roller 431 moves to the required pressing height, the locking member 434 locks the adjusted fourth pressing roller 431, keeping it in the corresponding position. During the continuous transport of the steel belt, the film belt passes through the area between the fourth pressing roller 431 and the lower surface of the steel belt, and is continuously rolled by the fourth pressing roller 431 to achieve adhesion between the lower surface of the film belt and the steel belt.

[0051] Since the height of the fourth pressure roller 431 can be adjusted first and then fixed in position by the locking member 434, the position of the fourth pressure roller 431 can be prevented from changing during continuous rolling, thus keeping the pressure state of the lower surface stable.

[0052] See Figure 7 As shown: the left limiting frame 22 and the right limiting frame 23 in the guiding module 2 can be adjusted laterally relative to the first guiding frame 21 to change the width of the guiding channel; the movable guiding roller 242 in the pressurizing unit 24 can be adjusted relative to the fixed guiding roller 241 to change the width of the movable guiding gap, so that coated steel strips of different thicknesses are subjected to corresponding secondary rolling pressure when passing through the movable guiding gap.

[0053] The guide module 2 also includes a first electric push rod 25 that can drive the left limiting frame 22 and the right limiting frame 23 to slide laterally. There are two first electric push rods 25, which are arranged opposite to each other on both sides of the frame 1 and are fixedly connected to the left limiting frame 22 and the right limiting frame 23 respectively.

[0054] When steel strips of different widths enter the guide module 2, the left limiting frame 22 and the right limiting frame 23 are adjusted according to the current steel strip width, so that the two move laterally along the first guide frame 21, thereby changing the width of the guide channel formed between the left limiting frame 22 and the right limiting frame 23, so that the guide channel corresponds to the current steel strip width.

[0055] Simultaneously, when coated steel strips of different thicknesses pass through the pressurizing unit 24, the position of the movable guide roller 242 relative to the fixed guide roller 241 is adjusted according to the thickness of the coated steel strip, thereby changing the movable guide gap between the fixed guide roller 241 and the movable guide roller 242. After the coated steel strip enters the movable guide gap, the fixed guide roller 241 and the movable guide roller 242 roll over the coated steel strip from both sides, so that the coated steel strip is subjected to secondary pressure while continuing to be conveyed.

[0056] Therefore, when the steel strip enters the equipment, it can be laterally limited by the left limit frame 22 and the right limit frame 23. After the coating is completed, the steel strips of different thicknesses can be pressed by the fixed guide roller 241 and the movable guide roller 242, so that the steel strip maintains a relatively stable transmission state before and after coating.

[0057] See Figure 8 As shown: It also includes a membrane material detection module 5, which includes detectors 51 and receivers 52. Two detectors 51 are provided, and are respectively tilted and fixedly disposed on one side of the first fixing frame 32 and the second fixing frame 41. Two receivers 52 are provided, and are respectively sleeved and installed at the ends of the first membrane roll 33 and the second membrane roll 42. When the first membrane roll 33 and the second membrane roll 42 rotate, they respectively drive the corresponding receivers 52 to rotate, so that the receivers 52 periodically pass through the detection area of ​​the corresponding detectors 51. When the membrane strip on the first membrane roll 33 or the second membrane roll 42 is continuously pulled and conveyed, the corresponding membrane roll remains in a rotating state, and the detectors 51 continuously detect the corresponding receivers 52. When the membrane strip on the corresponding membrane roll is exhausted, the membrane roll stops rotating, so that the detectors 51 cannot detect the receivers 52 within a preset time, thereby determining that the membrane strip on the corresponding membrane roll is exhausted and issuing a membrane replacement prompt.

[0058] As the first membrane roll 33 and the second membrane roll 42 continuously feed membrane strips onto the steel belt, the membrane strips are pulled by the continuous transmission of the steel belt, causing the first membrane roll 33 and the second membrane roll 42 to remain in a rotating state. Since the two receivers 52 are respectively installed at the ends of the first membrane roll 33 and the second membrane roll 42, the rotation of the corresponding membrane rolls can drive the receivers 52 to rotate synchronously, so that the receivers 52 periodically pass through the detection area of ​​the corresponding detector 51. The detector 51 can thus continuously obtain the detection signal that the corresponding membrane roll is in a rotating state.

[0059] As the membrane belt continues to output, when the membrane belt on the first membrane roll 33 or the second membrane roll 42 gradually runs out and loses its continuous traction on the corresponding membrane roll, the corresponding membrane roll stops rotating, and the receiver 52 installed at the end of the membrane roll also stops rotating. When the detector 51 fails to detect the corresponding receiver 52 for a preset time, it can determine that the corresponding membrane roll has stopped rotating, and thus determine that the membrane material on the corresponding membrane roll is exhausted, so as to issue a corresponding membrane replacement prompt.

[0060] By setting the detector 51 on one side of the first fixing frame 32 and the second fixing frame 41, and corresponding to the receiver 52 on the first membrane roll 33 and the second membrane roll 42 respectively, the upper and lower membrane rolls can be independently detected in terms of membrane material status, without the need to directly detect the remaining length of the membrane strip through contact.

[0061] This invention enables fully automated, uniform, and precise coating of the upper and lower surfaces of a steel strip.

[0062] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention.
