Description

Technical Field

[0001] This utility model relates to the field of steel drum remanufacturing technology, specifically to a heated grinding machine for steel drum remanufacturing. Background Technology

[0002] Steel drum remanufacturing involves cleaning, rust removal, grinding, shaping, and recoating of old steel drums to achieve resource recycling. The heated grinding machine used in steel drum remanufacturing is a piece of equipment specifically designed for the resource utilization of old steel drums (such as chemical waste drums). It combines heating and grinding functions, primarily used to remove surface rust, old coatings, or impurities, and softens the material through preheating to improve grinding efficiency and surface treatment quality.

[0003] The existing technology has the following shortcomings: When the existing grinding machine grinds the steel drum, the paint on the surface of the steel drum cannot be heated evenly, which makes it impossible for the paint to soften sufficiently. This makes it impossible for the grinding parts to grind different parts of the steel drum surface stably and thoroughly, resulting in paint residue on the surface of the steel drum, which will affect the efficiency of subsequent steel drum remanufacturing. Utility Model Content

[0004] The purpose of this invention is to provide a heated grinding machine for remanufacturing steel drums. The heating plate can heat and soften the paint on the surface of the steel drum, and the rotation of the support roller can drive the steel drum to rotate, so that the grinding plate can grind different positions on the surface of the steel drum, thereby improving the grinding efficiency of the steel drum and solving the above-mentioned shortcomings in the technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a heated grinding machine for steel drum remanufacturing, comprising a main body and further comprising:

[0006] A limiting mechanism located inside the device body and a grinding mechanism located on the top of the device body;

[0007] The device body includes a fixed base, with mounting brackets fixedly installed at both ends of the fixed base. A control panel is fixedly installed on one outer wall of the mounting bracket. A heating plate is fixedly installed on the top of the fixed base. Support rollers are rotatably installed on both outer walls of the two mounting brackets. A first motor is provided at one end of one of the support rollers. Synchronous pulleys are fixedly sleeved on the outer side of one end of each of the two support rollers. Synchronous belts are movably sleeved on the outer side of each of the two synchronous pulleys.

[0008] The grinding mechanism includes a movable plate disposed on the top inner side of two mounting brackets. A third hydraulic cylinder is disposed on the top of both ends of the movable plate. A fixed rack is fixedly installed on the outer wall of one side of the movable plate. A mounting plate is disposed on the inner side of the movable plate. A third motor is fixedly installed on the top of the mounting plate. A grinding plate is mounted on the output shaft of the third motor. A second motor is fixedly installed on one side of the top of the mounting plate. A movable gear that meshes with the fixed rack is fixedly sleeved on the output shaft of the second motor.

[0009] Preferably, the limiting mechanism includes a fixed plate and two second hydraulic cylinders. The fixed plate is fixedly installed on a fixed plate on one side of the outer wall of the fixed base. Two first hydraulic cylinders are fixedly installed on the top of one side of the outer wall of the fixed plate. A baffle plate is fixedly installed on one end of the piston rod of the two first hydraulic cylinders.

[0010] Preferably, the two second hydraulic cylinders are respectively fixedly installed on the outer wall of one opposite end of the two mounting brackets, and the piston rods of the two second hydraulic cylinders are fixedly installed with limiting plates. The two limiting plates are respectively connected to the two ends of the steel barrel, and the top of the two mounting brackets are provided with movable grooves.

[0011] Preferably, movable seats are fixedly installed on the outer walls of both ends of the movable plate, the outer walls of the two movable seats are slidably connected to the inner walls of the two movable slots respectively, the tops of the two mounting brackets are fixedly connected to the two third hydraulic cylinders respectively, and the piston rods of the two third hydraulic cylinders are fixedly connected to the tops of the two movable seats respectively.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] 1. The heating plate can heat and soften the paint on the surface of the steel drum. The rotation of the two support rollers can drive the steel drum to rotate, making the paint soften more thoroughly. At the same time, the height of the movable plate can be adjusted by the operation of the two third hydraulic cylinders. The second motor drives the movable gear to rotate. Through the meshing between the movable gear and the fixed rack, the grinding plate can be moved laterally, so that the grinding plate can grind different parts of the steel drum surface, making the grinding of the steel drum more thorough and improving the efficiency of steel drum remanufacturing.

[0026] This utility model provides, for example Figure 1 The heated grinding machine shown includes a main body 1, and further includes:

[0027] The limiting mechanism 2 is located inside the device body 1, and the grinding mechanism 3 is located on the top of the device body 1.

[0028] In order to stably heat and emulsify the paint on the surface of the steel drum, such as Figure 1-3 As shown, the device body 1 includes a fixed base 101, with mounting brackets 102 fixedly installed at both ends of the fixed base 101. A control panel 103 is fixedly installed on one outer wall of the mounting bracket 102. A heating plate 105 is fixedly installed on the top of the fixed base 101. Support rollers 106 are rotatably installed on both outer walls of the two mounting brackets 102. A first motor 107 is provided at one end of one of the support rollers 106. Synchronous pulleys 108 are fixedly sleeved on the outer sides of one end of each of the two support rollers 106. Synchronous belts 109 are movably sleeved on the outer sides of the two synchronous pulleys 108. The control panel 103 enables the heating plate 105 to heat the surface of the steel drum. The control panel 103 also enables the first motor 107 to drive one of the support rollers 106 to rotate. Through the transmission action of the synchronous pulley 108 and the synchronous belt 109, the other support roller 106 rotates synchronously. Due to the friction between the support roller 106 and the steel drum, the steel drum rotates on top of the support roller 106, allowing the heating plate 105 to heat different parts of the steel drum surface, thereby fully heating and emulsifying the paint on the steel drum surface.

[0029] To facilitate the polishing of the steel drum surface, such as Figure 1-4 As shown, the grinding mechanism 3 includes a movable plate 301 disposed on the top inner side of two mounting brackets 102. A third hydraulic cylinder 303 is disposed at the top of both ends of the movable plate 301. A fixed rack 305 is fixedly mounted on the outer wall of one side of the movable plate 301. A mounting plate 307 is disposed on the inner side of the movable plate 301. A third motor 310 is fixedly mounted on the top of the mounting plate 307. A grinding plate 311 is mounted on the output shaft of the third motor 310. A second motor 308 is fixedly mounted on one side of the top of the mounting plate 307. The output shaft of the second motor 308 is fixedly sleeved with a component that meshes with the fixed rack 305. The movable gear 309 and two third hydraulic cylinders 303 drive the movable plate 301 to move inside the mounting bracket 102, which can adjust the height of the grinding plate 311. The control panel 103 causes the second motor 308 to rotate. Through the meshing action between the movable gear 309 and the fixed rack 305, the mounting plate 307 moves inside the movable plate 301, which can adjust the lateral position of the grinding plate 311. The control panel 103 causes the third motor 310 to drive the grinding plate 311 to rotate, which can grind the surface of the steel barrel.

[0030] To ensure the steel drum remains stable during rotation, such as Figure 1-3As shown, the limiting mechanism 2 includes a fixed plate 201 and two second hydraulic cylinders 204. The fixed plate 201 is fixedly installed on the outer wall of one side of the fixed base 101. Two first hydraulic cylinders 202 are fixedly installed on the top of the outer wall of one side of the fixed plate 201. A baffle plate 203 is fixedly installed on one end of the piston rod of the two first hydraulic cylinders 202. The two second hydraulic cylinders 204 are respectively fixedly installed on the outer walls of the opposite ends of the two mounting brackets 102. A limiting plate 205 is fixedly installed on the piston rod of each of the two second hydraulic cylinders 204. The two limiting plates 205 are respectively connected to the two sides of the steel drum. The two mounting brackets 102 are connected by end contact. Each bracket has a movable groove 104 on its top. The two first hydraulic cylinders 202 drive the baffle plate 203 to extend or retract, which can push the steel drum out from the top of the support roller 106 and also block the steel drum. The two second hydraulic cylinders 204 drive the limiting plate 205 to extend or retract. The two limiting plates 205 can abut the two ends of the steel drum, so that the steel drum can rotate between the two limiting plates 205. This allows the steel drum to rotate stably on the top of the support roller 106 and prevents the steel drum from moving laterally.

[0031] In order to stably adjust the position of the grinding plate 311, such as Figure 2-4 As shown, movable seats 302 are fixedly installed on the outer walls of both ends of the movable plate 301. The outer walls of the two movable seats 302 are slidably connected to the inner walls of the two movable slots 104 respectively. The tops of the two mounting brackets 102 are fixedly connected to the two third hydraulic cylinders 303 respectively. The piston rods of the two third hydraulic cylinders 303 are fixedly connected to the tops of the two movable seats 302 respectively. A limiting groove 304 is opened on the inner side of the movable plate 301. A slide rail 306 is fixedly installed on one side of the outer wall of the movable plate 301. The inner wall of the limiting groove 304 is slidably connected to the outer wall of the mounting plate 307. The outer wall of the slide rail 306 is slidably connected to the inner wall of one side of the mounting plate 307. The length of the limiting groove 304 is greater than the length of the steel barrel. The third hydraulic cylinder 303 drives the movable seat 302 to move along the inner wall of the adjacent movable slot 104, so that the movable plate 301 moves stably inside the mounting bracket 102. At the same time, the limiting groove 304 and the slide rail 306 can limit the movement of the mounting plate 307, so that the grinding plate 311 remains stable during the adjustment process.

[0032] During the remanufacturing of the steel drum, its surface needs to be polished. The steel drum is placed on top of two support rollers 106. The heating plate 105 can heat the surface of the steel drum through the control panel 103. At the same time, the first motor 107 drives one of the support rollers 106 to rotate through the control panel 103. Through the transmission action of the synchronous pulley 108 and the synchronous belt 109, the other support roller 106 rotates accordingly. The friction between the support roller 106 and the steel drum can drive the steel drum to rotate, thereby allowing the heating plate 105 to heat the surface of the steel drum. The paint surface at different locations is heated and emulsified. The control panel 103 causes the two second hydraulic cylinders 204 to extend or retract, which in turn moves the two limiting plates 205. The two limiting plates 205 can limit the two ends of the steel barrel, so that the steel barrel remains stable during rotation. At the same time, the control panel 103 causes the two third hydraulic cylinders 303 to extend, which in turn moves the movable seat 302 along the inner wall of the adjacent movable groove 104. This can then move the movable plate 301 inside the mounting frame 102, allowing the height of the grinding plate 311 to be adjusted.

[0033] The control panel 103 drives the third motor 310 to rotate the grinding plate 311, which can grind the surface of the steel drum. The control panel 103 also drives the second motor 308 to rotate the movable gear 309. Through the meshing action between the movable gear 309 and the fixed rack 305, the mounting plate 307 moves along the outer wall of the slide rail 306 from the inner wall of the limiting groove 304, thereby adjusting the lateral position of the grinding plate 311. This allows the grinding plate 311 to grind different parts of the steel drum surface. After the steel drum is ground, the control panel 103 extends the two first hydraulic cylinders 202, which allows the baffle plate 203 to push the steel drum out from the top of the support roller 106, making it convenient for workers to replace the steel drum and improving the efficiency of steel drum remanufacturing. This embodiment specifically solves the problem in the prior art where the steel drum surface cannot be uniformly heated, resulting in incomplete grinding of the steel drum surface.

[0034] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
