Description

Technical Field

[0001] This invention relates to the field of steel coil embossing technology, specifically to a continuous online embossing device for color-coated steel coils. Background Technology

[0002] As a high-performance composite material, color-coated steel coils have been widely used in many fields due to their unique advantages. They not only possess the high mechanical strength and easy formability inherent in steel, meeting the processing requirements of various structures and shapes, but also have the excellent decorative properties of organic materials, presenting a rich variety of appearances. Therefore, they occupy an important position in many fields such as construction, home appliances, and furniture.

[0003] To further enhance the decorative and functional properties of color-coated steel coils and better adapt them to the needs of different scenarios, embossing patterns onto the surface of color-coated steel coils using an embossing machine has become a common processing method.

[0004] Existing steel coil embossing equipment varies in structure, but they typically include some core components. The base and frame provide a stable support foundation for the entire device; the embossing roller assembly is crucial for embossing, comprising a main roller and an auxiliary roller. The ends of these rollers are mounted in bearing housings via bearings (such as deep groove ball bearings or self-aligning roller bearings), which are then connected to the frame, ensuring stable installation and flexible rotation of the rollers during operation. The drive mechanism generally consists of a motor, sprockets, and chains. The motor provides power, which drives the sprockets via the chain, thereby causing the main and auxiliary rollers to rotate synchronously. This allows the steel coil to be embossed with the corresponding patterns as it passes between the two rollers, completing the embossing process.

[0005] However, existing embossing devices have significant limitations in practical applications. They can only perform embossing with a single pattern, and when the pattern needs to be adjusted according to different production requirements, the operation is extremely cumbersome. Operators must spend a considerable amount of time first disassembling the connection between the bearing housing and the frame, and then disassembling the bearing housing and the end shaft of the pressure roller before they can change to a pressure roller with a different pattern. This operation method is not only time-consuming and labor-intensive, seriously affecting processing efficiency, but the frequent disassembly and installation may also affect the accuracy and stability of the equipment, thereby increasing production costs and making it difficult to meet the requirements of efficient and flexible processing in modern production. Summary of the Invention

An annular baffle is fixedly provided at the end of the inner support tube, and the annular baffle is fitted to the annular support plate.

[0012] Preferably, the embossing mechanism further includes a braking device, which includes two arc-shaped clamps that are hinged to each other at one end and detachably connected at the other end. The inner sidewall of the arc-shaped clamps is configured as a stepped structure, and multiple third slots are provided on the sidewall of the arc-shaped clamps with smaller diameter. The larger diameter end of the two arc-shaped clamps is sleeved on the outer support tube, and the smaller diameter end is sleeved on the inner support tube, and the locking post is set through the third slot.

[0013] Preferably, the pushing mechanism includes a frame, an upper wheel and a lower wheel that are installed vertically on the inner side of the frame; the arc-shaped sidewalls of the upper wheel and the lower wheel are adapted to the outer sidewall of the inner support tube, and the upper wheel and the lower wheel clamp the inner support tube, while a first motor installed on the outer side of the frame controls the rotation of the upper wheel or the lower wheel.

[0014] Preferably, the frame includes a top frame with a U-shaped structure, two bottom plates installed at the bottom of the top frame, and a connecting plate installed vertically at the top of the top frame; the connecting plate has an L-shaped structure, and the end of the connecting plate away from the top frame is inserted into the connecting frame at the top of the support end piece; the plug plate installed at the top of the bottom plate is inserted into the plug groove of the top frame, and the bottom plate and the top frame are connected by bolts; the end axle of the upper wheel body is connected through the top frame by a bearing, and the end axle of the lower wheel body is connected through the bottom plate by a bearing.

[0015] Preferably, the support frame includes a base frame and multiple vertical beams installed at the two opposite edges of the base frame, the vertical beams being configured as I-beams; the support end piece is located between the two vertical beams, and the vertical beams pass through the snap-fit ​​grooves on the edge of the support end piece; limit devices are provided on both the upper and lower sides of the junction of the two support end pieces, the limit devices controlling the lower embossing roller to be at the corresponding height; the limit device includes two symmetrically arranged clamping plates sleeved on the vertical beams, the edges of the clamping plates being connected by edge bolts; a central bolt is provided through the center of the limit device located below the support end piece, the central bolt passing through a limit hole in the vertical beam.

[0017] The beneficial effects of this invention are:

[0018] 1. The present invention provides a support frame, and multiple embossing mechanisms are arranged side by side on the inner side of the support frame. At the same time, a pressure regulating mechanism is provided on the top of the support frame. The steel coil output from the take-up and untake-down frame passes through the multiple embossing mechanisms in sequence. The pressure regulating mechanism adjusts the state of the embossing mechanism, forcing the embossing mechanism to apply pressure to the steel coil to achieve embossing treatment.

[0019] 2. The inner support tube of this invention is designed to move relative to the outer support tube, and the end of the inner support tube can be detachably inserted into the embossing roller. This allows the inner support tube to be easily pulled out and moved relative to the outer support tube as needed, controlling the insertion or removal of the end of the inner support tube from the embossing roller. This facilitates the disassembly and replacement of the embossing roller, changing the previous situation where the bearing seat and frame had to be disassembled first, followed by the bearing seat and embossing roller. This reduces the time required to replace the embossing roller and improves its replacement efficiency.

[0020] 3. The present invention also includes a pushing mechanism, which is sleeved on the end of the inner support tube. The pushing mechanism is detachable from the support end piece. Therefore, the movement of the inner support tube can be controlled while the pushing mechanism is working, reducing the labor intensity of pulling the inner support tube. Because the pushing mechanism is highly flexible, it can be installed at the end of different inner support tubes to realize the replacement of multiple embossing rollers.

Detailed Implementation

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0039] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0040] Example 1

[0041] To enable the extrusion process of color-coated steel coils, this embodiment provides an embossing device for color-coated steel coils. Under the action of the embossing device, grooves are formed on the surface of the color-coated steel coil. The uneven surface increases the contact area between the coating and the steel plate, allowing the coating to adhere more firmly to the steel plate, reducing the risk of coating peeling due to factors such as alternating temperature and vibration, and indirectly extending the service life of the color-coated steel coil.

[0042] like Figure 1As shown, specifically, the embossing device includes take-up and untake-down frames 1 and embossing components 2 arranged adjacent to each other. The take-up and untake-down frames 1 use publicly available equipment, such as a coiler, and their number is determined according to actual needs. If the steel coil, after being processed by the embossing components 2, directly enters the next process, such as the cutting process, the take-up and untake-down frames 1 can be set on the side of the embossing components 2 away from the cutting process. These frames support the steel coil and facilitate its unwinding. If the steel coil, after being processed by the embossing components 2, does not directly enter the next process, it needs to be coiled. Therefore, take-up and untake-down frames 1 are set on both sides of the embossing components 2; one frame 1 facilitates the unwinding of the steel coil, and the other frame 1 facilitates its coil winding.

[0043] like Figure 2 As shown, to achieve the embossing process on the steel coil, the embossing assembly 2 includes a support frame 3, a pressure adjusting mechanism 5, and multiple sets of embossing mechanisms 4. The multiple sets of embossing mechanisms 4 are arranged side-by-side inside the support frame 3, and the pressure adjusting mechanism 5 is located at the top of the support frame 3. The pressure adjusting mechanism 5 adjusts the state of the embossing mechanisms 4, applying pressure to the steel coil as it passes through the multiple sets of embossing mechanisms 4 sequentially, thereby creating corresponding patterns on the surface of the steel coil. The number of embossing mechanisms 4 can be determined according to actual needs; for example, it can be set to one, two, or three sets.

[0044] like Figure 4 , Figure 6 As shown, each embossing mechanism 4 specifically includes two embossing rollers 41 distributed vertically, an inner support tube 46 detachably inserted into the end of the embossing roller 41, an outer support tube 44 sleeved on the inner support tube 46, and a support end piece 42 sleeved on the outer support tube 44. The support end piece 42 is adjustablely connected to the support frame 3. Therefore, under the action of the support end piece 42, the lower embossing roller 41 can be stably connected to the support frame 3, and the upper embossing roller 41 can be slidably connected to the support frame 4 under the action of the support end piece 42. In this configuration, the pressure adjusting mechanism 5 is connected to the upper embossing roller 41, so that the height of the upper embossing roller 41 can be adjusted under the action of the pressure adjusting mechanism 5, so that the upper and lower embossing rollers 41 are positioned close together, thereby pressing the steel coil passing through the gap between the two embossing rollers 41. The vertically distributed embossing rollers 41 are the core components of the embossing process, and their surfaces have specific patterns.

[0045] like Figure 4 , Figure 6As shown, the inner support tube 46 is movably disposed relative to the outer support tube 44, and the end of the inner support tube 46 can be detachably inserted into the end of the embossing roller 41. Therefore, under the condition of ensuring stable installation of the embossing roller 41, the inner support tube 46 can be moved relative to the outer support tube 44 by driving it, and the end of the inner support tube 46 can be disengaged from the embossing roller 41 to release the restriction of the embossing roller 41. This facilitates the disassembly of the embossing roller 41 as needed and its replacement with an embossing roller 41 of the corresponding pattern, providing support for completing different pattern embossing processes, reducing the replacement time of the embossing roller 41, and improving its replacement efficiency. In order to control the relatively stable installation of the inner support tube 46 and the outer support tube 44, a braking device 45 is provided at the end of the outer support tube 44, which can control the inner support tube 46 to remain stationary relative to the outer support tube 44 under the action of the braking device 45.

[0046] To control the rotation of the embossing roller 41, the device also needs to be equipped with a publicly available drive mechanism. This drive mechanism generally includes a motor (referred to as the second motor in this document), sprockets, and chains. The sprockets are respectively mounted on the end of the outer support tube 44 and the power output shaft of the second motor. The second motor provides power, drives the sprockets through the chain, and thus makes the two embossing rollers 41 rotate synchronously to achieve the embossing process on the steel coil.

[0047] Of course, a pre-existing guiding mechanism, including guide rollers and guide wheels, can also be installed as needed. This mechanism is mounted on the support frame 3 or the take-up / untake-down frame 1, near the conveyor opening of the take-up / untake-down frame 1 or before and after the embossing roller 41. Its function is to guide the steel coil, ensuring it maintains a straight line during transport, preventing skewing and guaranteeing embossing quality.

[0048] Example 2

[0049] like Figure 6 , Figure 11 As shown, based on Embodiment 1, in order to control the stable connection between the inner support tube 46 and the outer support tube 44, and to facilitate the movement of the inner support tube 46 relative to the outer support tube 44, the braking device 45 includes two vertically distributed arc-shaped clamping plates 451. One end of the two arc-shaped clamping plates 451 is hinged together, and the other end is detachably connected by bolts. Therefore, the two arc-shaped clamping plates 451 can be detachably sleeved on the end of the outer support tube 44. In addition, the inner sidewall of the arc-shaped clamping plate 451 is set with a stepped structure, and multiple third slots 452 are provided on the sidewall with the smaller diameter of the arc-shaped clamping plate 451. Two arc-shaped clamping plates 451 are also provided. The larger diameter end is fitted onto the outer support tube 44, and the smaller diameter end is fitted onto the inner support tube 46. The clamping post 461 is set through the third clamping groove 452. Therefore, by utilizing the structural characteristics of the arc-shaped clamping plates 451, the inner support tube 46 and the outer support tube 44 can be stably clamped, and the inner support tube 46 can be braked, thereby stably supporting the embossing roller 41.

[0050] Example 3

[0051] like Figure 6 As shown, based on Embodiment 1 or 2, to achieve stable installation of the inner support tube 46 and the outer support tube 44, the length of the inner support tube 46 is greater than the length of the outer support tube 44, and the length of the outer support tube 44 is greater than the thickness of the support end piece 42. The outer support tube 44 is connected through the support end piece 42 via a bearing. This arrangement achieves stable installation of the inner support tube 46 and facilitates the rotation of the embossing roller 41 by the inner support tube 46. A sprocket is installed at the end of the outer support tube 44 that protrudes from the support end piece 42. Therefore, when the second motor is operating, the outer support tube 44 can be controlled to drive the inner support tube 46 to rotate, thereby controlling the rotation of the embossing roller 41.

[0052] like Figure 8 , Figure 9 As shown, in order to achieve a stable connection between the inner support tube 46 and the outer support tube 44, multiple second slots 441 with open ends are evenly arranged on the inner side wall of the outer support tube 44 along its circumferential direction. Multiple locking posts 461 are fixedly arranged on the outer side wall of the inner support tube 46. The locking posts 461 are arranged through the second slots 441. When the inner support tube 46 and the outer support tube 44 rotate synchronously, it facilitates the disassembly of the embossing roller 41 by pulling the inner support tube 46 relative to the outer support tube 44.

[0053] like Figure 5 , Figure 9 As shown, to achieve a stable connection between the embossing roller 41 and the inner support tube 46, the embossing roller 41 is configured as a tube structure, and an annular support plate 411 is fixedly installed on the inner side of the embossing roller 41. Multiple first slots 412 are provided on the side wall of the central channel of the annular support plate 411. The end of the inner support tube 46 is inserted into the channel of the annular support plate 411, and the locking post 461 is inserted into the first slot 412. An annular baffle 462 is fixedly installed at the end of the inner support tube 46, and the annular baffle 462 is fitted against the annular support plate 411. With this configuration, the end of the inner support tube 46 is stably inserted into the embossing roller 41, and the restriction between the inner support tube 46 and the embossing roller 41 can be released when the inner support tube 46 moves, thus facilitating the replacement of the embossing roller 41.

[0054] Example 4

[0055] like Figure 3 , Figure 6As shown, based on embodiments 1, 2, or 3, in order to stably install the support end piece 42 on the support frame 3, the support frame 3 includes a bottom frame 31 and multiple vertical beams 32 installed vertically at two opposite edges of the bottom frame 31. The vertical beams 32 are configured as I-beams. The support end piece 42 is located between the two vertical beams 32, and a snap-fit ​​groove 421 with both ends open is provided on the vertical side wall of the support end piece 42. The vertical beams 32 are provided through the snap-fit ​​grooves 421 on the edge of the support end piece 42 to achieve sliding contact between the support end piece 42 and the vertical beams 32.

[0056] like Figure 4 As shown, when the support end piece 42 is slidably connected to the vertical beam 32, in order to ensure that the lower embossing roller 41 of each embossing mechanism 4 is stably installed relative to the support frame 3, a limit device 43 is provided at the end corner of the support end piece 42 of each embossing roller 41.

[0057] like Figure 10 As shown, the limiting device 43 includes two symmetrically arranged clamping plates 431 sleeved on the vertical beam 32. The edges of the clamping plates 431 are connected by side bolts 432, that is, under the action of the side bolts 432, the clamping plates 431 are fastened to the vertical beam 32, and the support end piece 42 can be stably installed relative to the vertical beam 32 by the clamping plates 431.

[0058] like Figure 10 As shown, since limiting devices 43 are set on both the upper and lower sides of the same vertical edge of the supporting end piece 42 to control the position of the supporting end piece 42, in order to enhance the strength of the lower limiting device 43, a central bolt 433 is provided through the middle of the limiting device 43 located below the supporting end piece 42. The central bolt 433 is provided through a limiting hole 33 of the vertical beam 32. This arrangement not only increases the stability of the supporting end piece 42, but also allows the position of the supporting limiting device 43 to be adjusted according to the needs, thereby adjusting the height of the lower supporting end piece 42 and the embossing roller 41.

[0059] like Figure 14 , Figure 15As shown, when the support end piece 42 is slidably connected to the vertical beam 32, in order to facilitate the adjustment of the position of the embossing roller 41 on the upper side of each embossing mechanism 4 and the adjustment of the pressure applied to the steel coil by the two embossing rollers 41, the pressure adjustment mechanism 5 includes a first beam 51 installed on the top of the vertical beam 32, a second beam 52 vertically arranged below the first beam 51, and multiple diagonal bracing plates 54 arranged below the second beam 52. The top of the second beam 52 is fixedly arranged through a snap-fit ​​plate 56 below the first beam 51, which not only ensures a stable connection between the first beam 51 and the second beam 52, but also facilitates the movement of the second beam 52 relative to the first beam 51. The second beam 52 is configured with a U-shaped structure, and a telescopic cylinder 53 is provided on the inner side of the second beam 52. The main body of the telescopic cylinder 53 is installed at the first beam 51, so the movement of the second beam 52 relative to the first beam 51 can be controlled by the telescopic cylinder 53.

[0060] like Figure 2 , Figure 14 As shown, when the second beam 52 is movable, bearing seats 55 are connected to both the upper and lower ends of the diagonal brace 54. The upper bearing seat 55 is connected to the second beam 52, and the lower bearing seat 55 is mounted on the support end piece 42 at the end of the upper embossing roller 41. This arrangement not only achieves a stable connection between the support end piece 42 and the support frame 3, but also allows adjustment of the tilt angle of the diagonal brace 54 when the second beam 52 moves, controlling the support end piece 42 to drive the upper embossing roller 41 to rise and fall, thereby adjusting the pressure applied to the steel coil.

[0061] Example 5

[0062] like Figure 6 As shown, based on embodiments 1, 2, 3 or 4, in order to facilitate the pulling of the inner support tube 46 and reduce the labor intensity of the workers, a pushing mechanism 6 is installed at the end of the inner support tube 46. The pushing mechanism 6 controls the inner support tube 46 to move along its axial direction, so that the inner support tube 46 can be controlled to detach from or be inserted into the embossing roller 1 by the action of the pushing mechanism 6.

[0063] like Figure 12 As shown, specifically, the pushing mechanism 6 includes a frame 64 and an upper wheel 61 and a lower wheel 62, which are installed vertically on the inner side of the frame 64. The arc-shaped sidewalls of the upper wheel 61 and the lower wheel 62 are adapted to the outer sidewall of the inner support tube 46, and an anti-slip layer is provided on the sidewalls of the upper wheel 61 and the lower wheel 62 that contact the inner support tube 46. At the same time, the upper wheel 61 and the lower wheel 62 clamp the inner support tube 46. In addition, the first motor 63 installed on the outside of the frame 64 controls the rotation of the upper wheel 61 or the lower wheel 62. Under the action of the friction between the wheel and the inner support tube 46, the inner support tube 46 is driven to move relative to the pushing mechanism 6, thereby realizing the pulling of the inner support tube 46.

[0064] like Figure 13 As shown, to facilitate the clamping of the inner support tube 46 by the upper wheel 61 and the lower wheel 62, the frame 64 includes a top frame 641 with a U-shaped structure, two base plates 644 installed at the bottom of the top frame 641, and a connecting plate 645 vertically installed at the top of the top frame 641. A connector plate 643 installed at the top of the base plate 644 is inserted into the connector slot 642 of the top frame 641, and the base plate 644 and the top frame 641 are connected by bolts. The end shaft of the upper wheel 61 is connected through the top frame 641 via a bearing, and the end shaft of the lower wheel 62 is connected through the base plate 644 via a bearing. When the upper wheel 61 and the lower wheel 62 are distributed on the upper and lower sides of the inner support tube 46, the length of the connector plate 643 inserted into the connector slot 642 can be adjusted by rotating the bolts, thereby controlling the clamping of the inner support tube 46 by the upper wheel 61 and the lower wheel 62.

[0065] like Figure 7 , Figure 13 As shown, to ensure stable installation of the pushing mechanism 6 relative to the support end member 42, the connecting plate 645 is configured with an L-shaped structure, and the end of the connecting plate 645 away from the top frame 641 is inserted into the connecting frame 422 at the top of the support end member 42, thereby achieving a detachable connection between the pushing mechanism 6 and the support end member 42. This allows for the assembly and disassembly of multiple inner support tubes 46 and embossing rollers 41 when equipped with a corresponding number of pushing mechanisms 6. In this embodiment, two sets of pushing mechanisms 6 can be provided, respectively installed on the inner support tubes 46 at both ends of the same embossing roller 41.

[0066] Furthermore, the technical solutions of the various embodiments of the present invention can be combined with each other, but only if they are feasible for those skilled in the art.
