Description

Technical Field

[0001] This utility model relates to the field of building roofing engineering technology, and in particular to a metal roofing seam sealing machine that can easily adjust the gap of the rolling forming rollers, can complete the seam rolling forming in one step, and helps to ensure the size and quality of the seams. Background Technology

[0002] Metal roofing refers to a roofing system that uses metal sheets as the roofing material, combining the structural layer and the waterproofing layer into one. With the advancement of architectural engineering and materials science, metal roofing systems have developed rapidly and offer numerous advantages, such as high durability, resistance to corrosion, ultraviolet radiation, and harsh weather conditions. They also possess excellent waterproofing and thermal insulation properties. Furthermore, their diverse material choices and flexible designs allow them to adapt to various architectural needs, providing aesthetically pleasing, practical, and cost-effective solutions for buildings. Typically, metal sheets are joined by interlocking the male and female ribs, and finally connected using a standing seam with rolled edges. However, achieving effective waterproofing with standing seam metal roofing panels requires scientific and reasonable construction methods, effective detailed treatment plans, and high-quality equipment to ensure proper waterproofing.

[0003] Currently, the market for standing seam roofing systems primarily offers 360° and 540° seam types. The 360° seam type doesn't meet higher wind resistance requirements, typically requiring wind-resistant clips to be added to the seam ribs for enhanced wind resistance, which increases material and installation costs and affects the overall aesthetics of the roof. The 540° seam, on the other hand, offers better wind resistance without the need for additional clips, achieving higher wind resistance. However, 540° seam machines on the market usually require two seams to achieve a 540° seam, resulting in low efficiency. Furthermore, the secondary seam rolling process damages the original coating of the roofing material due to repeated rolling stress, causing cracks in the anti-corrosion layer and ultimately leading to leaks. The patent title is "An Electric Seam Machine for Color Steel Plates with Fixing Function..." Chinese utility model patent No. ZL201921105080.1, published on April 14, 2020, includes a machine body, an adjustment box, a reducer, a motor, and casters. The adjustment box is mounted on the top of the machine body via fastening bolts, and the reducer is mounted on the top of the adjustment box via fastening bolts. The motor is mounted on one side of the top of the reducer via a support frame, and the bottom output end of the motor is geared to the top input shaft of the reducer. The bottom output shaft of the reducer is connected to a rotating wheel shaft via a connecting sleeve, and the bottom end of the rotating wheel shaft passes through the adjustment box and the machine body, mounting a driving forming wheel via a pin. The driving forming wheel has a left-hand oblique thread on its outer periphery. An axial fixed cam is welded to one side of the machine body, and a forming wheel bearing seat is provided on one side of the axial fixed cam. A forming wheel shaft is fitted between the forming wheel bearing seats. This utility model, an electric lock-sewing machine for color steel plates with a fixing function, is reasonably designed, has a simple structure, and is suitable for widespread promotion and use. However, the main function of this patent is to achieve the locking function by cooperating with the active forming roller and the forming roller shaft. However, the active forming roller and the forming roller shaft are relatively fixed in this solution, and cannot be adjusted well according to the thickness of the metal roofing material. When the gap is too large, it is easy to cause the locking to become loose, and when the gap is too small, it may cause the equipment to jam. The locking effect is not good when used, and it is not possible to complete the 540° locking in one go.

[0004] How to solve the above problems has become an urgent technical issue. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please refer to Figure 1-12This utility model provides a metal roofing seam locking machine, including a guide wheel body 1 and a forming wheel body 2 that can cooperate with the guide wheel body 1. The guide wheel body 1 and the forming wheel body 2 are connected together by an opening and closing handle assembly 3 that can adjust the distance between the guide wheel body 1 and the forming wheel body 2. A drive assembly 4 is provided on the guide wheel body 1. A guide wheel assembly 6 is provided at the lower end of the guide wheel body 1 and can be connected to the output shaft of the drive assembly 4 through a guide wheel transmission assembly 5. A forming wheel assembly 8 is provided at the lower end of the forming wheel body 2 and can be correspondingly cooperated with the guide wheel assembly 6 through a forming wheel transmission assembly 7. A master wheel 10 is provided at the front end, and a driven wheel 20 that can cooperate with the master wheel 10 is provided at the front end of the forming wheel body 2. Traveling wheels 9 are provided at the bottom of both the guide wheel body 1 and the forming wheel body 2. The guide wheel body 1 and the forming wheel body 2 move by raising the traveling wheels 9. The drive component 4 drives the guide wheel group 6 and the forming wheel group 8 through the guide wheel transmission group 5 and the forming wheel transmission group 7. The opening and closing handle component 3 can adjust the distance between the guide wheel body 1 and the forming wheel body 2. The gap between the guide wheel group 6 and the forming wheel group 8 during roll forming can be easily adjusted according to the thickness of the roof raw material and the size of the roof lock seam overlap rib. This allows for the adjustment of the seam gap. The cooperation between the main wheel 10 and the driven wheel 20 facilitates the guidance of the roofing material during seam rolling, ensuring seam size and quality to a certain extent. Furthermore, multiple wheels can be paired within the wheel assembly 6 and forming wheel assembly 8 to form multiple seam rolling forming wheel structures, enabling one-time seam rolling. In particular, it can achieve 360° and 540° seam rolling in a single operation, greatly improving the seam sealing effect, enhancing versatility, and avoiding multiple rolling operations on the roofing material, preventing damage to the original... The coating of the material is damaged due to repeated rolling stress, which effectively prevents the roof material from failing in its anti-corrosion function. The setting of the main roller 10 and the driven roller 20 increases the number of roof seam tracks. The main roller 10 and the driven roller 20 work together to perform preliminary rolling on the metal roof material, preventing the roof seam ribs from jumping. During seam locking, the stress of the metal roof material can be better released, avoiding damage to the metal roof material. Moreover, the main roller 10 and the driven roller 20 do not require power, which also helps to reduce the load on the equipment, facilitates high-altitude operations, and is also conducive to further processing by the wheel set 6 and the forming wheel set 8.

[0033] In this invention, the forming wheel body 2 includes two movable bodies 21 arranged sequentially along the length of the wheel-supporting body 1, which can correspondingly cooperate with the wheel-supporting body 1. The opening and closing handle assembly 3 includes an opening and closing handle 31 and an opening and closing connecting shaft 32 that can connect the two movable bodies 21 to the wheel-supporting body 1 respectively. The front end of the opening and closing connecting shaft 32 is threadedly connected to a clearance adjusting nut 33 through the interior of the two movable bodies 21 and extending to the other end of the wheel-supporting body 1. The rear end of the opening and closing connecting shaft 32 is connected by a locking cam. The 34 is movably connected to the opening and closing handle 31. The main guide wheel 10 and the driven wheel 20 are connected together by a buffer spring 101. The opening and closing handle assembly 3 also includes an opening and closing spring 36 and an adjusting spring 35. The opening and closing spring 36 is correspondingly connected between the guide wheel body 1 and the movable body 21, and the adjusting spring 35 is connected between the gap adjusting nut 33 and the guide wheel body 1. The forming wheel body 2 consists of two movable bodies 21, which can be controlled in segments, reducing spring pressure and facilitating manual operation. The opening and closing handle 31, the opening and closing connecting shaft 32 and the gap are connected together. The gap adjustment nut 33, when engaged, allows for setting and adjusting the distance between the guide wheel body 1 and the two movable bodies 21, thus facilitating the adjustment of the locking gap. The opening and closing spring 36, in conjunction with the adjusting spring 35, provides the guide wheel body 1 and the movable body 21 with buffering and rebound capabilities during forward movement. For example, when the locking gap encounters the metal roof fixing seat, the fixing seat, sandwiched between the male and female overlapping ribs of the metal roof, causes the thickness of the locking gap overlapping ribs to increase. When the locking gap reaches the fixing seat, the guide wheel body 1 and the movable body 21 will separate by a certain distance as the thickness of the locking gap overlapping ribs increases. At this time, the opening and closing spring 36 is stretched and the adjusting spring 35 is compressed. After passing the fixed seat, the opening and closing spring 36 and the adjusting spring 35 automatically rebound under the elastic action, so that the distance between the wheel body 1 and the movable body 21 is restored to the original set parameters. Therefore, it can ensure that the locking rib will not be rolled, deformed and cracked at the locking seam overlap rib support, and at the same time, it can ensure the size and quality of the locking seam, and reduce the failure rate of the body when locking the roof. The adjusting spring 35 can adopt a conical butterfly spring washer structure, which has sufficient elasticity and can provide high load support or buffer in a limited space.

[0034] In this invention, the guide wheel assembly 6 and the forming wheel assembly 8 are combined to form at least four pairs of forming wheel structures. The guide wheel transmission assembly 5 includes a first guide wheel gear assembly 51, a second guide wheel gear assembly 52, and a drive gear 53 connecting the first guide wheel gear assembly 51 and the second guide wheel gear assembly 52. ​​The first guide wheel gear assembly 51 is located within the guide wheel body 1 near the main guide wheel 10, and the second guide wheel gear assembly 52 is located within the guide wheel body 1 away from the main guide wheel 10. The forming wheel transmission assembly 7 includes a first forming wheel gear assembly 71 that can correspondingly engage with the first guide wheel gear assembly 51, and a second forming wheel gear assembly 72 that can correspondingly engage with the second guide wheel gear assembly 52. ​​The first forming wheel gear assembly 71 is located within the first movable body 21 near the main guide wheel 10, and the second forming wheel gear assembly 52 is located within the first movable body 21 near the main guide wheel 10. The forming wheel gear set 72 is located in the second movable body 21, away from the main guide wheel 10. The guide wheel set 6 is correspondingly located at the bottom of the first guide wheel gear set 51 and the second guide wheel gear set 52. The forming wheel set 8 is correspondingly located at the bottom of the first forming wheel gear set 71 and the second forming wheel gear set 72. Depending on the situation, the guide wheel set 6 and the forming wheel set 8 can be set into four or more pairs to form a multi-set forming wheel structure, which is suitable for completing roof seam locking operations of various specifications and sizes at one time, meeting different needs. The guide wheel set 6 and the forming wheel set 8 have a large number of wheel tracks, which helps to solve the problem of sealing roof materials with large rolling forming angles. Moreover, the combination of the guide wheel set 6 and the forming wheel set 8 with multiple wheel tracks helps to release the internal stress of the metal material, which can reduce the cracking of deformed roof materials.

[0035] In this utility model, the guide wheel assembly 6 is provided with at least four guide wheels. The guide wheel assembly 6 includes a first guide wheel 61, a second guide wheel 62, a third guide wheel 63, and a fourth guide wheel 64. The first guide wheel 61, the second guide wheel 62, the third guide wheel 63, and the fourth guide wheel 64 are arranged sequentially along the length direction of the guide wheel body 1 and are correspondingly disposed at the bottom of the first guide wheel gear assembly 51 and the second guide wheel gear assembly 52. ​​The first guide wheel 61 is disposed at the bottom of the first guide wheel gear assembly 51 near the main guide wheel 10, the second guide wheel 62 is disposed at the bottom of the first guide wheel gear assembly 51 away from the main guide wheel 10, the third guide wheel 63 is disposed at the bottom of the second guide wheel gear assembly 52 near the first guide wheel gear assembly 51, and the fourth guide wheel 64 is disposed at the bottom of the second guide wheel gear assembly 52 away from the first guide wheel gear assembly 51. The forming wheel assembly 8 includes a first forming wheel 81, a second guide wheel 82, a third guide wheel 63, and a fourth guide wheel 64 that can respectively cooperate with the first guide wheel 61, the second guide wheel 62, the third guide wheel 63, and the fourth guide wheel 64. The system comprises a second forming wheel 82, a third forming wheel 83, and a fourth forming wheel 84. The first forming wheel 81 and the second forming wheel 82 are located at the bottom of a movable body 21 near the main guide wheel 10, while the third forming wheel 83 and the fourth forming wheel 84 are located at the bottom of another movable body 21 away from the main guide wheel 10. The first guide wheel 61, in conjunction with the first forming wheel 81, and the second guide wheel 62, in conjunction with the second forming wheel 82, can lock the roof ribs at 450°. The third guide wheel 63, in conjunction with the third forming wheel 83, and the fourth guide wheel 64, in conjunction with the fourth forming wheel 84, can complete the 540° seam formation. These four sets of multiple pairs of wheels pass through the seam sequentially, allowing for step-by-step processing of the metal roof seam. This enables the rolling, bending, and folding of the metal roof material, facilitating one-time seam rolling and forming without the need for secondary seam rolling, avoiding multiple rolling processes on the roof material, preventing cracking of the anti-corrosion layer, and ensuring the anti-corrosion function of the roof material.

[0036] In this invention, guide pads 11 are evenly distributed along the length of the guide wheel body 1 at the bottom, guiding the opening and closing of the movable body 21 and assisting in the forming of the locking seam. A guide wheel body cover 12 is provided on the upper end surface of the guide wheel body 1. Limiting seats 13 are provided at both the front and rear ends of the upper end surface of the guide wheel body cover 12, which can limit the displacement height of the movable body 21. A lifting handle 14 is provided on the limiting seat 13. A handle that can engage with the limiting seat is provided on the upper end surface of the movable body 21. The bottom of the movable body cover plate 22 is in contact with the bottom; the guide plate 11 can assist the roller assembly 6 and the forming roller assembly 8 in bending, rolling and other work on the metal roofing material. At the same time, the guide plate 11 and the limit seat 13 can guide and limit the displacement of the movable body 21 to a certain extent, so that the movable body 21 can be aligned with the roller body 1 as much as possible, and achieve synchronous forward and backward movement to ensure smooth operation. The lifting handle 14 can easily move the roller body 1 and the movable body 21, which is beneficial to personnel operation.

[0037] In this utility model, the drive component 4 includes a motor 41 and a speed changer 42. The speed changer 42 is mounted on the cover plate 12 of the wheel-mounted machine body. The output shaft of the speed changer 42 is connected to the drive gear 53. The motor 41 is mounted on the upper end of the speed changer 42. The output shaft of the motor 41 is connected to the input end of the speed changer 42. The motor 41 can be a 220V brushed high-power motor. The motor has high power and small size, and it is not easy to overload when locking the seams. The locking wheel is not easy to slip on the locking rib of the roof, thus avoiding wear on the galvanized anti-corrosion layer of the roof.

[0038] In practical use, this utility model involves selecting appropriate specifications for the first support wheel 61 and the first forming wheel 81, the second support wheel 62 and the second forming wheel 82, the third support wheel 63 and the third forming wheel 83, and the fourth support wheel 64 and the fourth forming wheel 84, and sequentially installing them on the corresponding output ends of the support wheel transmission group 5 and the forming wheel transmission group 7. Appropriate guide wheels 10 and driven wheels 20 are installed at the front ends of the support wheel body 1 and the movable body 21. Then, the distance between the two movable bodies 21 and the support wheel body 1 is set using the opening and closing handle 31, the opening and closing connecting shaft 32, and the gap adjusting nut 33. The distances between the guide wheels 10 and the driven wheels 20, the first support wheel 61 and the first forming wheel 81, the second support wheel 62 and the second forming wheel 82, the third support wheel 63 and the third forming wheel 83, and the fourth support wheel 64 and the fourth forming wheel 84 are adjusted. Finally, the distance is adjusted by moving... The moving wheel 9 moves the guide wheel body 1 and the movable body 21, aligning the main guide wheel 10 and the driven wheel 20 with the roof seam ribs. After starting the motor 41 and the speed changer 42, the guide wheel body 1 and the movable body 21 can be moved by pulling the handle 14 to start normal operation. During seam locking, the main guide wheel 10 and the driven wheel 20 first perform preliminary rolling treatment on the roof seam ribs to prevent the roof seam ribs from jumping off the edges and guide the forward direction. In the second part, the first guide wheel 61 and the first forming wheel 81 cooperate, and the second guide wheel 62 and the second forming wheel 82 cooperate to lock the roof seam ribs at 450°.
