Description

Technical Field

[0001] This invention relates to the field of galvanized steel scaffolding production technology, and in particular to a galvanized steel scaffolding edge trimming and leveling device. Background Technology

[0002] The production process of galvanized steel scaffolding boards involves multiple processing steps, one of which is edge cutting and punching. However, due to the pressure of edge cutting and punching, deformation and unevenness can easily occur, requiring the galvanized steel scaffolding boards to be leveled.

[0003] Chinese patent CN217528777U discloses a sheet metal leveling device for the production and processing of galvanized steel scaffolding, including a leveling heating table base surface, and support legs are fixedly installed on the lower surface of the leveling heating table base surface near the four corners. The sheet metal leveling device for the production and processing of galvanized steel scaffolding can level the sheet metal of galvanized steel scaffolding through the pressing and pressing of the leveling rollers and the base surface of the leveling heating table. This improves the bending and forming quality of the galvanized steel scaffolding in the later stages. It can also conduct heat to the base surface of the leveling heating table through the heat-conducting column, raising the temperature of the galvanized steel scaffolding passing over the base surface. This makes it easier to deform during the sheet metal leveling process and can avoid or reduce damage caused by low-temperature deformation of the metal. Although the above patent can level galvanized steel scaffolding, the flange placement groove is long and narrow, which causes the adjacent positions of the holes of the galvanized steel scaffolding to be suspended and unsupported along the length direction, making it difficult to level and affecting the leveling and finished product quality of the galvanized steel scaffolding.

[0004] The present invention aims to solve the problems existing in the above-mentioned patents. To this end, a galvanized steel scaffold edge trimming and leveling device is proposed, which can comprehensively level the area around and sides of the holes in the galvanized steel scaffold, thereby improving the leveling and finished product quality of the galvanized steel scaffold. Summary of the Invention

[0005] To overcome the shortcomings of the aforementioned patents, which, although capable of leveling galvanized steel scaffolding, suffer from the drawback of the flange placement groove being elongated, causing adjacent holes in the galvanized steel scaffolding to be suspended and unsupported along the length direction, thus hindering leveling and affecting the quality of the finished product, this invention provides a galvanized steel scaffolding edge-cutting and leveling device capable of comprehensively leveling the area around and sides of the holes in galvanized steel scaffolding, thereby improving the leveling and quality of the finished product.

[0006] This invention is achieved through the following technical solution: A galvanized steel scaffold trimming and leveling device includes a base and symmetrically mounted electric slide rails on the top of the base. Movable seats are fixedly connected between the moving parts of the electric slide rails. The device also includes a support base, a cylinder, a heating module, a fixing frame, U-shaped rods, pressure rollers, and connecting springs. The support base is slidably connected to the movable seat. The top of the support base has evenly spaced grooves for placing flanges of holes in the galvanized steel scaffold. The heating module is installed inside the support base. Fixing frames are symmetrically fixed to the top of the base. U-shaped rods are slidably connected between the fixing frames, and connecting springs connect the U-shaped rods to the fixing frames. A pressure roller is rotatably mounted on the U-shaped rod above the support seat. A cylinder is fixedly connected to the movable seat, and the end of the cylinder's telescopic rod is fixedly connected to the support seat. The cylinder is used to drive the support seat to move upward and make full contact with the galvanized steel plank for support. The pressure roller presses the galvanized steel plank onto the support seat. Then, when the galvanized steel plank moves to the right, the electric slide rail drives the support seat to move synchronously to the right with the galvanized steel plank and remain in a relatively stationary state. The support seat continuously supports the galvanized steel plank, and the pressure roller performs full follow-up leveling of the galvanized steel plank through the support seat.

[0007] Further explanation: The galvanized steel scaffold trimming and leveling device also includes a cleaning component. The cleaning component includes a housing fixed to a movable base. The housing has an opening for the galvanized steel scaffold to pass through. A rotating shaft is rotatably connected to the housing. The rotating shaft is located on the upper and lower sides of the opening in the housing. A rotating component is provided between the rotating shaft and the housing to drive the rotating shaft to rotate. A brush roller is fixedly mounted on the rotating shaft to remove metal debris attached to the galvanized steel scaffold. An air jet component is provided on the housing to blow away the removed metal debris.

[0008] Further explanation: the rotating component includes a gear fixedly mounted on the rotating shaft, with the upper and lower gears meshing with each other, and a drive motor mounted on the outer side of the housing, with the output shaft end of the drive motor fixedly connected to the end of the rotating shaft.

[0009] Further explanation: the jet assembly includes jet pipes symmetrically fixed to the inside of the housing, with the jet end of the jet pipes facing the brush roller. An air inlet pipe is fixedly connected to the housing and communicates with the jet pipes.

[0010] Further explanation: the cleaning component also includes a discharge frame fixedly attached to the housing to discharge metal debris.

[0011] Further explanation: the galvanized steel scaffold trimming and leveling device also includes a top material assembly. The top material assembly includes a top material frame that slides vertically through the support base to limit the galvanized steel scaffold from the support base. Return springs are evenly spaced between the top material frame and the support base. A limit component is provided between the top material frame and the movable seat to limit the top material frame.

[0012] Further explanation: The limiting component includes iron rods symmetrically fixed to the front and rear sides of the top material frame, and magnetic blocks located directly above the iron rods are symmetrically fixed to the inner side of the movable seat to hold and fix the iron rods.

[0013] To further explain, the galvanized steel plank edge trimming and leveling device also includes a fixed frame fixed to the base, and a cooling pipe is fixedly connected to the fixed frame to cool the galvanized steel plank.

[0014] The beneficial effects of this invention are as follows: 1. Whenever the galvanized steel scaffold moves to the right and is above the support, the galvanized steel scaffold contacts the pressure roller, and the support moves to contact the galvanized steel scaffold. The flange around the hole of the galvanized steel scaffold is in the groove. Then, when the galvanized steel scaffold moves to the right, the electric slide rail is activated, so that the support moves to the right and the galvanized steel scaffold moves synchronously. The pressure roller cooperates with the support to level the galvanized steel scaffold as it moves to the right. Since the support contacts the area around the hole and the side of the galvanized steel scaffold, the galvanized steel scaffold is fully leveled, thereby improving the leveling of the galvanized steel scaffold and the quality of the finished product.

[0015] 2. Under the action of the brush roller, whenever the galvanized steel scaffold moves to the right, the brush roller can remove the metal debris attached to the galvanized steel scaffold. After the metal debris is removed, the galvanized steel scaffold is leveled to prevent the metal debris from causing the galvanized steel scaffold to dent during the leveling process and affecting the surface flatness, thereby ensuring the finished quality of the galvanized steel scaffold.

[0016] 3. Under the action of the top material frame, whenever the support moves downward, the top material frame can limit the galvanized steel scaffolding, so that the galvanized steel scaffolding can be smoothly separated from the support. This can prevent the galvanized steel scaffolding from getting stuck on the support after being leveled, which would make it difficult to remove the material and cause hard tearing deformation, thus ensuring the safety of removing the galvanized steel scaffolding.

[0027] First, it should be noted that in different described embodiments, the same components are given the same reference numerals or the same component names. The disclosure contained throughout this specification can be applied semantically to the same components having the same reference numerals or the same component names. The location descriptions selected in the specification, such as upper, lower, and lateral, also refer to the directly described and illustrated figures and are semantically applied to the new location when the location changes.

[0028] Example: A galvanized steel scaffolding edge trimming and leveling device, please refer to [link / reference]. Figures 1-6As shown, the device includes a base 1 and electric slide rails 2 symmetrically mounted on the top of the base 1. Movable seats 3 are fixedly connected between the moving parts of the electric slide rails 2 on both sides. It also includes a support 4, a cylinder 51, a heating module 6, a fixing frame 8, a U-shaped rod 9, a pressure roller 10, and a connecting spring 11. The support 4 is vertically slidably connected to the movable seat 3. The top of the support 4 has evenly spaced grooves 5 for placing the flanges of the galvanized steel plank holes. The heating module 6 is installed inside the support 4. Fixing frames 8 are symmetrically fixed to the top center of the base 1. U-shaped rods 9 slide between the fixing frames 8 on both sides. The upper parts of the U-shaped rods 9 on both sides are connected to the tops of the fixing frames 8 on both sides. A connecting spring 11 is attached, and a pressure roller 10 is rotatably mounted on the lower part of the U-shaped rod 9. The pressure roller 10 is located above the support seat 4. A cylinder 51 is fixedly connected to the middle of the movable seat 3. The end of the telescopic rod of the cylinder 51 is fixedly connected to the bottom of the support seat 4. The cylinder 51 is used to drive the support seat 4 to move upward and make full contact with the galvanized steel scaffold for support. The pressure roller 10 presses the galvanized steel scaffold onto the support seat 4. Then, when the galvanized steel scaffold moves to the right, the electric slide rail 2 drives the support seat 4 to move synchronously to the right with the galvanized steel scaffold through the movable seat 3 and is in a relatively stationary state. The support seat 4 continuously supports the galvanized steel scaffold, and the pressure roller 10 performs full follow-up leveling of the galvanized steel scaffold through the support seat 4.

[0029] Please see Figure 5 and Figure 6As shown, the galvanized steel scaffold trimming and leveling device also includes a cleaning assembly mounted on the base 1. The cleaning assembly includes a housing 13, a rotating shaft 131, an air jet assembly, a rotating assembly, a brush roller 136, and a discharge frame 137. The housing 13 is fixedly connected to the top left side of the base 1. The upper part of the left and right sides of the housing 13 has openings for the galvanized steel scaffold to pass through. Two rotating shafts 131 are rotatably connected between the front and rear sides of the housing 13. The rotating shafts 131 are located on the upper and lower sides of the openings of the housing 13. A rotating assembly is provided between the rotating shafts 131 and the housing 13. When the rotating assembly operates, it can drive the rotating shafts 131 to rotate. The brush roller 136 is fixedly mounted in the middle of the upper and lower rotating shafts 131. When the brush roller 136 rotates, it can remove the metal debris attached to the galvanized steel scaffold. An air jet assembly is provided on the housing 13. When the air jet is sprayed... When the air assembly is in operation, the air jet assembly can blow away the cleaned metal debris. A discharge frame 137 is fixedly connected to the bottom middle of the housing 13, which can discharge the metal debris. The rotating assembly includes a drive motor 134 and gears 135. Gears 135 are fixedly mounted on the front side of the upper and lower rotating shafts 131. The upper and lower gears 135 mesh with each other. The drive motor 134 is installed on the outer front side of the housing 13. The output shaft end of the drive motor 134 is fixedly connected to the front end of the upper rotating shaft 131. The air jet assembly includes an air jet pipe 132 and an air inlet pipe 133. The air jet pipes 132 are symmetrically fixedly connected to the upper and lower right side of the housing 13. The air jet end of the air jet pipe 132 faces the brush roller 136. The air inlet pipe 133 is fixedly connected to the front side of the housing 13. The air outlet end of the air inlet pipe 133 is fixedly connected to and communicates with the front ends of the upper and lower air jet pipes 132.

[0030] First, place this device next to the edge-cutting and punching machine 31, so that the left side of this device corresponds to the discharge end of the edge-cutting and punching machine 31. Connect an external air pump to the air jet pipe 132 and start the external air pump to discharge air into the air jet pipe 132. The air jet pipe 132 then sprays out the air. At the same time, start the drive motor 134 to drive the upper rotating shaft 131 to rotate. The upper rotating shaft 131 drives the lower rotating shaft 131 to rotate through two gears 135. The rotation of the upper and lower rotating shafts 131 drives the upper and lower brush rollers 136 to rotate. Then, each time the galvanized steel scaffold is edge-cut and punched by the machine, the edge-cutting and punching galvanized steel scaffold moves to the right. This is repeated, so that the galvanized steel scaffold moves intermittently to the right. The galvanized steel scaffold moves to the right through the opening of the housing 13 to the support. Above seat 4, the galvanized steel scaffolding contacts the pressure roller 10. The flange of the galvanized steel scaffolding corresponds to the groove 5. The upper and lower brush rollers 136 contact the upper and lower sides of the galvanized steel scaffolding respectively. The upper and lower brush rollers 136 rotate to remove the metal debris attached to the galvanized steel scaffolding after the edges are cut and punched. The air jet pipe 132 sprays air to blow the removed metal debris downwards, causing the metal debris to be discharged into the discharge frame 137. The discharge frame 137 discharges and collects the metal debris. This prevents the metal debris from causing the galvanized steel scaffolding to dent during the leveling process, affecting the surface flatness, thereby ensuring the finished quality of the galvanized steel scaffolding. Then, the cylinder 51 is activated. The extension rod of the cylinder 51 extends, causing the support seat 4 to move upwards. The support seat 4 moves upwards and contacts the galvanized steel scaffolding. When the flange around the hole of the galvanized steel scaffolding is in the groove 5, the cylinder 51 is closed, and the support seat 4 stops moving upward. Under the action of the connecting spring 11, the pressure roller 10 presses the galvanized steel scaffolding onto the support seat 4. The heating module 6 is started to heat the support seat 4, and the support seat 4 heats the galvanized steel scaffolding, making the galvanized steel scaffolding easier to deform. Then, when the edge cutting and punching machine 31 completes the edge cutting and punching of the galvanized steel scaffolding again, the galvanized steel scaffolding moves to the right again. At this time, the electric slide rail 2 is started to drive the movable seat 3 to move to the right, and the movable seat 3 drives the support seat 4 to move to the right. The support seat 4 and the galvanized steel scaffolding move to the right synchronously and are in a relatively stationary state. The pressure roller 10 then follows up and levels the galvanized steel scaffolding that has been supported by the support seat 4, so that the galvanized steel scaffolding is more easily deformed. The galvanized steel scaffolding is flatter, and because the support seat 4 contacts the area around the holes and sides of the galvanized steel scaffolding, the galvanized steel scaffolding is fully leveled, thus improving the leveling of the tin-plated steel scaffolding and the quality of the finished product. When the galvanized steel scaffolding stops moving to the right, the electric slide rail 2 is turned off, the support seat 4 stops moving to the right, and the cylinder 51 is started to move the support seat 4 downward to reset and disengage from the galvanized steel scaffolding. Then, during the process of the tin-plated steel scaffolding stopping and being trimmed and punched, the electric slide rail 2 is started to move to the left, which drives the movable seat 3 to move to the left to reset. The movable seat 3 drives the support seat 4 to move to the left to reset, and the reset support seat 4 corresponds to the next part of the galvanized steel scaffolding. This process is repeated, and the galvanized steel scaffolding can be continuously moved to the right to perform a comprehensive leveling process.After all the tin-plated steel scaffolding boards have been leveled, turn off the external air pump, stop the air jet pipe 132 from spraying air, then turn off the drive motor 134, and the brush roller 136 stops rotating.

[0031] Please see Figure 7 and Figure 8 As shown, the galvanized steel scaffold trimming and leveling device also includes a top-feeding assembly installed between the movable seat 3 and the support seat 4. The top-feeding assembly includes a top-feeding frame 14, return springs 141, and a limiting assembly. The top-feeding frame 14 is vertically slidably connected to the support seat 4. The top-feeding frame 14 can limit the galvanized steel scaffold to detach from the support seat 4. Six return springs 141 are evenly spaced between the bottom of the top-feeding frame 14 and the bottom of the support seat 4. The top-feeding frame 14 and the movable seat 3 are connected... A limit component is provided. When the limit component is in operation, it can limit the top material frame 14. The limit component includes an iron rod 142 and a magnetic block 143. The iron rod 142 is symmetrically fixed to both the front and rear sides of the top material frame 14. The magnetic block 143 is symmetrically fixed to the upper part of both the front and rear sides of the movable seat 3. The magnetic block 143 is located directly above the iron rod 142. When the iron rod 142 contacts the magnetic block 143, the magnetic block 143 can attract and fix the iron rod 142.

[0032] When the support seat 4 moves upward and contacts the galvanized steel scaffold, the upward movement of the support seat 4 drives the top support frame 14 to move upward via the return spring 141. The upward movement of the top support frame 14 drives the iron rod 142 to move upward. When the support seat 4 moves upward and contacts the galvanized steel scaffold, the support seat 4 stops moving upward. At this time, the iron rod 142 contacts the magnetic block 143, and the magnetic block 143 attracts the iron rod 142. After the galvanized steel scaffold is leveled once, the support seat 4 moves downward. Because the magnetic block 143 attracts the iron rod 142, the magnetic force is greater than the elastic force of the return spring 141, and the iron rod 142 causes the top support frame 142 to move upward. 4. When the support 4 remains stationary, the downward movement of the support 4 first compresses the return spring 141. Since the top support 14 remains stationary, it limits the galvanized steel scaffold, causing it to disengage from the downward-moving support 4. When the return spring 141 is compressed to its maximum stroke, the support 4 continues to move downward, driving the top support 14 downward through the return spring 141. The downward movement of the top support 14 causes the iron rod 142 to move downward, disengaging it from the magnetic block 143. Due to the action of the return spring 141, the top support 14 retracts back into the support 4. This prevents the galvanized steel scaffold from getting stuck on the support 4 after leveling, which could lead to difficulty in unloading and cause hard deformation, thus ensuring the safety of unloading the galvanized steel scaffold.

[0033] Please see Figure 9As shown, the galvanized steel scaffolding edge trimming and leveling device also includes a fixed frame 15 and a cooling pipe 16. The fixed frame 15 is fixedly connected to the top right side of the base 1, and the cooling pipe 16 is fixedly connected to the fixed frame 15. The cooling pipe 16 can cool the galvanized steel scaffolding.

[0034] When the galvanized steel scaffolding moves to the right and passes through the fixed frame 15, the cooling pipe 16 is activated. The cooling pipe 16 dissipates cold air to cool the leveled galvanized steel scaffolding. After all the galvanized steel scaffolding has been leveled, the cooling pipe 16 is turned off. This prevents the galvanized steel scaffolding from overheating and affecting subsequent processing, thus facilitating the subsequent handling of the galvanized steel scaffolding.

[0035] Finally, it is necessary to note that the above content is only used to help understand the technical solution of the present invention and should not be construed as a limitation on the scope of protection of the present invention; any non-essential improvements and adjustments made by those skilled in the art based on the above content of the present invention are all within the scope of protection claimed by the present invention.
