Description

Technical Field

[0001] The present invention relates to the technical field of conveying mechanisms, and specifically to a conveying mechanism for metal surface treatment. Background Art

[0002] Polishing is a process for processing the surface of an object. By using various grinding tools and abrasives, operations such as friction and cutting are performed on the surface of the object to improve surface quality, accuracy, smoothness, etc., and defects such as burrs, flash, oxide scale, scratches, sand holes, etc. on the surface of the object can be removed to make the surface more flat and uniform. For example, after casting, there are some burrs and unevenness on the surface of metal castings, which can be removed by polishing to improve the quality of the castings.

[0003] For conveyors used in metal surface treatment, most of them are for manual installation of workpieces for polishing treatment and transportation.

Before use, the driving motor is powered on, the sorted workpieces are stacked and placed in a material frame, or other machines are used to store the workpieces in the material frame. When the motor drives the belt to rotate, the belt drives the fixing plate to move forward, and the slider fixedly connected to the fixing plate passes through the sliding groove to support the workpiece stored on the partition, driving the workpiece to move forward and be fixed by the fixing plate to move forward, thereby performing grinding. Through the above components, the tediousness of manually placing the workpieces one by one is eliminated. The force of the belt transportation is used to make the fixed plate push the workpieces stacked in the material frame, thereby improving the working efficiency of the machine, and making the speed of the transportation tool depend on the transportation speed of the belt rather than the speed of manual installation of the workpieces, thereby improving the processing efficiency of the equipment and avoiding the situation that the number of workpieces placed on the fixed plate during manual loading is less than the number of workpieces that can actually be installed, thereby reducing the processing efficiency; and the material frame can also be loaded manually, the material frame is in a fixed state, and the workpieces are stacked, which is more efficient than manual installation on a running belt, has a higher installation success rate, and the material frame has the function of storing stacked workpieces.

Utilizing the characteristics of the above-mentioned material frame stacking, when the sliding block on the upper part of the fixed plate enters the fixed plate through the sliding groove to push the workpiece forward, the discharge port of the fixed plate is set to an oblique port, which is slightly larger than the thickness of the workpiece, so as to avoid the workpiece from pressing against the inner wall of the material frame due to the own characteristics of the belt when the workpiece moves outward, resulting in damage to the fixed plate. The set oblique port can prevent the discharge port from being too large, avoid the two workpieces from moving forward at the same time, make the excess workpiece higher than the fixed plate, and enter the grinding area without being fixed, so that the force applied by the grinder causes the unfixed workpiece to fly everywhere, causing damage to the machine.

[0014] Preferably, the grinding assembly includes a grinding box fixedly connected to the outer wall of the transport shell, the inner wall of the grinding box is rotatably connected to the driving shaft 2, the inner wall of the grinding box is rotatably connected to the rotating shaft, the outer wall of the driving shaft 2 is fixedly connected to the outer wall of the pinion gear, the outer wall of the driving shaft 2 is rotatably connected to the sanding belt, the end of the sanding belt away from the sanding belt is rotatably connected to the outer wall of the rotating shaft, and the top of the grinding box is rotatably connected to the rotating door, and the characteristic of the belt single-point connection fixing plate is utilized to drive the drive motor to drive the transmission shaft to rotate slowly, so that the transmission shaft drives the power roller to rotate, and the belt is controlled to rotate for transportation, and the large gear fixed on the transmission shaft is connected to the small gear part on the compound gear through a toothed belt, the large gear is larger than the small gear part of the compound gear, and when the large gear rotates one circle, the small gear will rotate The belt drives the fixed plate to move forward, and the workpiece fixed by the fixed plate will generate more dust after being polished and fall on the belt. When the belt passes through a corner, because the belt and the fixed plate are fixed at a single point, the fixed plate will open up the space other than the fixed point at the corner of the belt due to the change in angle, so that the workpiece will be separated from the fixed plate due to its own weight and fall below. At the same time, the dust accumulated at the inner corner of the fixed plate during polishing will also fall to the bottom of the equipment due to the force generated by the change in the shape of the fixed plate.

[0015] The present invention has the following beneficial effects: The present invention aims to solve the problem of slow manual loading. When the motor drives the belt to rotate, and the belt drives the fixed plate to move forward, the slider fixedly connected to the fixed plate will pass through the sliding groove to support the workpiece stored on the partition, thereby driving the workpiece to move forward and be fixed by the fixed plate to move forward, so as to be polished by the sand belt. Through the above components, the tediousness of manually placing the workpieces one by one is eliminated. The force of the belt transportation is used to push the workpieces stacked in the material frame, thereby improving the working efficiency of the machine, and making the speed of the transportation tool depend on the transportation speed of the belt, thereby improving the processing efficiency of the equipment, and avoiding the situation in which the number of workpieces placed on the fixed plate is less than the actual number of workpieces that can be installed during manual loading, thereby reducing the processing efficiency.

[0016] (2) The present invention utilizes the characteristics of the above-mentioned material frame stacking. When the slider on the upper part of the fixed plate enters the interior of the fixed plate through the sliding groove to push the workpiece forward, the discharge port of the fixed plate is set to be an oblique port, which is slightly larger than the thickness of the workpiece. This prevents the workpiece from pressing against the inner wall of the material frame due to the inherent characteristics of the belt when moving outward, thereby causing damage to the fixed plate. The oblique port can prevent the discharge port from being too large, and prevents two workpieces from moving forward at the same time, causing the excess workpiece to be higher than the fixed plate and enter the grinding area without being fixed. The force applied by the grinder causes the unfixed workpiece to fly everywhere, causing damage to the machine.

[0017] (3) The present invention utilizes the oblique characteristics of the pressure plate. When the slider fixed on the fixed plate drives the workpiece to move outward, the rear end of the workpiece is held forward by the slider and moves forward. When the workpiece leaves the range of the partition plate, the setting of the inclined plate of the pressure plate will cause the workpiece to move downward to squeeze the clamping plate, so that the clamping plate is contracted toward the inside of the slider through the clamping spring, so that the clamping spring cooperates with the clamping plate to squeeze and fix the workpiece and hold the fixed plate to move forward to the grinding assembly, thereby avoiding the workpiece from shaking due to the gap between the workpiece and the fixed plate during grinding, thereby affecting the grinding effect. At the same time, it is avoided that when the shaking is large, the workpiece leaves the range of the fixed plate, resulting in flying parts, thereby damaging the inner wall parts of the machine.

[0018] (4) The present invention utilizes the characteristic of the belt being connected to the fixed plate at a single point. The belt drives the fixed plate to move forward. The workpiece fixed by the fixed plate will generate a lot of dust after being polished and fall onto the belt. When the belt passes through a corner, because the belt and the fixed plate are fixed at a single point, the fixed plate will open up space other than the fixed point at the corner of the belt due to the change in angle, so that the workpiece will be separated from the fixed plate due to its own weight and fall downward. At the same time, the dust accumulated at the inner corner of the fixed plate during polishing will also fall to the bottom of the equipment due to the force generated by the change in the shape of the fixed plate.

When the workpiece leaves the range of the partition 215, the setting of the inclined plate of the pressure plate 213 will cause the workpiece to move downward and squeeze the clamping plate 224, so that the clamping plate 224 is retracted toward the inner side of the slider 222 through the clamping spring 223, so that the clamping spring 223 cooperates with the clamping plate 224 to squeeze and fix the fixed plate 221 to support the workpiece and move forward to reach the grinding assembly 32, so as to avoid the workpiece from shaking due to the gap between the workpiece and the fixed plate 221 during grinding, thereby affecting the grinding effect, and at the same time avoiding the workpiece from leaving the range of the fixed plate 221 when the shaking is large, resulting in flying parts, thereby damaging the inner wall parts of the machine.

[0031] For example 2, please refer to Figures 5 - 9The present invention is a conveying mechanism for metal surface treatment. On the basis of Example 1, the fixing assembly 22 includes a fixing plate 221 fixedly connected to the outer wall of the belt 116, the inner wall of the fixing plate 221 is fixedly connected with a clamping spring 223, the outer wall of the clamping spring 223 is fixedly connected with a clamping plate 224, and the outer wall of the fixing plate 221 is fixedly connected with a slider 222. The present invention aims at the problem of slow manual feeding. Before use, the driving motor 114 is powered on, the sorted workpieces are stacked and placed in the material frame 211, or other machines are used to make the workpieces enter the material frame 211 for storage. When the motor drives the belt 116 to rotate, the belt 116 drives the fixing plate 221 to move forward, and the slider 222 fixedly connected to the fixing plate 221 will pass through the sliding groove 214 to support the workpieces stored on the partition 215. The workpiece is driven to move forward and is fixed by the fixed plate 221 to move forward for grinding. Through the above components, the tediousness of placing the workpieces one by one manually is eliminated. The force of the belt 116 is used to push the workpieces stacked in the material frame 211, thereby improving the working efficiency of the machine, so that the speed of the transport tool depends on the transport speed of the belt 116 instead of the speed of manual installation of the workpieces, thereby improving the processing efficiency of the equipment and avoiding the situation that the number of workpieces placed on the fixed plate 221 is less than the actual number of workpieces that can be installed during manual loading, thereby reducing the processing efficiency; and the material frame 211 can also be loaded manually, the material frame 211 is in a fixed state, and the workpieces are stacked. Compared with manual installation on a running belt, it is more efficient and has a higher installation success rate, and the material frame 211 has the function of storing stacked workpieces.

[0032] The belt assembly 31 includes a large gear 311 fixedly connected to the outer wall of the transmission shaft 124, the outer wall of the large gear 311 is fixedly meshed with a toothed belt 312, the inner wall of the gear housing 113 is rotatably connected to a limiting column 313, the inner wall of the gear housing 113 is rotatably connected to a composite gear 314, the inner wall of the gear housing 113 is rotatably connected to a small gear 315, the outer wall of the small gear 315 is meshed with the outer wall of the composite gear 314, and the end of the toothed belt 312 away from the large gear 311 is meshed with the composite gear 314. By utilizing the stacking characteristics of the above-mentioned material frame 211, when the fixed plate 221 When the upper slider 222 enters the fixed plate 221 through the sliding groove 214 to push the workpiece forward, the discharge port of the fixed plate 221 is set to be an oblique port, which is slightly larger than the thickness of the workpiece to prevent the workpiece from pressing against the inner wall of the material frame 211 due to the inherent characteristics of the belt 116 when the workpiece moves outward, thereby causing damage to the fixed plate 221. The set oblique port can prevent the discharge port from being too large, and prevent two workpieces from moving forward at the same time, causing excess workpieces to be higher than the fixed plate 221, and enter the grinding area without being fixed, so that the force applied by the grinder causes the unfixed workpieces to fly everywhere, causing damage to the machine.

[0033] The grinding assembly 32 includes a grinding box 324 fixedly connected to the outer wall of the transport housing 115. A second drive shaft 321 is rotatably connected to the inner wall of the grinding box 324, and a rotating shaft 322 is rotatably connected to the inner wall of the grinding box 324. The outer wall of the second drive shaft 321 is fixedly connected to the outer wall of the small gear 315. A sand belt 323 is rotatably connected to the outer wall of the second drive shaft 321. One end of the sand belt 323 away from the sand belt 323 is rotatably connected to the outer wall of the rotating shaft 322. A rotating door 325 is rotatably connected to the top of the grinding box 324. Utilizing the characteristic of the single-point connection of the belt 116 to the fixing plate 221, the drive motor 114 drives the transmission shaft 124 to rotate slowly, so that the transmission shaft 124 drives the power roller 123 to rotate, controlling the belt 116 to rotate for transportation. The large gear 311 fixed on the transmission shaft 124 is connected to the small gear part of the compound gear 314 through a toothed belt 312. The large gear 311 is larger than the small gear part of the compound gear 314. When the large gear 311 rotates one circle, the small gear will rotate two circles or more, making the rotation speed of the compound gear 314 faster. The larger gear part of the compound gear 314 is connected to the small gear 315, so that the second drive shaft 321 and the belt 116 use the same motor, but the rotation speed of the second drive shaft 321 is faster, improving the grinding effect of the sand belt 323; the belt 116 drives the fixing plate 221 to move forward. The workpiece fixed on the fixing plate 221 will generate a lot of dust after being ground and fall on the belt 116. When the belt passes through the corner, because the fixing of the belt 116 to the fixing plate 221 is a single-point fixing, the fixing plate 221 will open the space except the fixing point due to the change of the angle at the corner of the belt 116, causing the workpiece to break away from the fixing of the fixing plate 221 due to its own weight and fall below. At the same time, the dust accumulated in the inner corner of the fixing plate 221 during grinding will also fall to the bottom of the equipment due to the change in the shape of the fixing plate 221, generating a force.

[0034] A specific application of this embodiment is: before use, the driving motor 114 is powered on, and the sorted workpieces are stacked and placed in the material frame 211, or other machines are used to place the workpieces in the material frame 211 for storage. When the motor drives the belt 116 to rotate, the belt 116 drives the fixed plate 221 to move forward, and the slider 222 fixedly connected to the fixed plate 221 passes through the sliding groove 214 to support the workpiece stored on the partition 215, driving the workpiece to move forward and be fixed by the fixed plate 221 to move forward, thereby performing grinding. Through the above components, the tediousness of manually placing the workpieces one by one is eliminated, and the belt 116 drives the fixed plate 221 to move forward. 16 The transport force causes the fixed plate 221 to push the workpieces stacked in the material frame 211, thereby improving the working efficiency of the machine and making the speed of the transport tool depend on the transport speed of the belt 116 rather than the speed of manually installing the workpieces, thereby improving the processing efficiency of the equipment and avoiding the situation in which the number of workpieces placed on the fixed plate 221 is less than the number of workpieces that can actually be installed during manual loading, thereby reducing the processing efficiency; and the material frame 211 can also be loaded manually, the material frame 211 is in a fixed state, and the workpieces are stacked, which is more efficient and has a higher installation success rate than manual installation on a running belt, and the material frame 211 has the function of storing stacked workpieces.

[0035] By utilizing the stacking characteristics of the above-mentioned material frame 211, when the slider 222 on the upper part of the fixed plate 221 enters the fixed plate 221 through the sliding groove 214 to push the workpiece forward, the discharge port of the fixed plate 221 is set to be an oblique port, which is slightly larger than the thickness of the workpiece, to prevent the workpiece from pressing against the inner wall of the material frame 211 due to the inherent characteristics of the belt 116 when moving outward, thereby causing damage to the fixed plate 221. The set oblique port can prevent the discharge port from being too large, and prevent two workpieces from moving forward at the same time, so that the excess workpiece is higher than the fixed plate 221 and enters the grinding area without being fixed, so that the force applied by the grinder causes the unfixed workpiece to fly everywhere, causing damage to the machine.

[0036] By utilizing the oblique characteristics of the pressure plate 213, when the slider 222 fixed on the fixed plate 221 drives the workpiece to move outward, the rear end of the workpiece is held by the slider 222 and moves forward. When the workpiece leaves the range of the partition 215, the setting of the inclined plate of the pressure plate 213 will cause the workpiece to move downward to squeeze the clamping plate 224, so that the clamping plate 224 is retracted toward the inside of the slider 222 through the clamping spring 223, so that the clamping spring 223 cooperates with the clamping plate 224 to squeeze and fix the fixed plate 221 to hold the workpiece forward and reach the grinding assembly 32, thereby avoiding the workpiece from shaking due to the gap between the workpiece and the fixed plate 221 during grinding, thereby affecting the grinding effect, and at the same time avoiding the workpiece from leaving the range of the fixed plate 221 when the shaking is large, resulting in flying parts, thereby damaging the inner wall parts of the machine.

[0037] By utilizing the characteristic of the belt 116 being connected to the fixed plate 221 at a single point, the driving motor 114 drives the transmission shaft 124 to rotate slowly, so that the transmission shaft 124 drives the power roller 123 to rotate, and controls the belt 116 to rotate for transportation. The large gear 311 fixed on the transmission shaft 124 is connected to the small gear part on the composite gear 314 through the toothed belt 312. The large gear 311 is larger than the small gear part of the composite gear 314. When the large gear 311 rotates one circle, the small gear will rotate two circles or more, so that the rotation speed of the composite gear 314 becomes faster. The large gear part of the composite gear 314 is connected to the small gear 315, so that the driving shaft 321 and the belt 116 use the same One motor, but the rotation speed of the second drive shaft 321 is faster, so that the grinding effect of the sanding belt 323 is improved; the belt 116 drives the fixed plate 221 to move forward, and the workpiece fixed by the fixed plate 221 will generate more dust after being polished, and fall on the belt 116. When the belt passes through the corner, because the belt 116 and the fixed plate 221 are fixed at a single point, the fixed plate 221 will open the space other than the fixed point at the corner of the belt 116 due to the change in angle, so that the workpiece is separated from the fixation of the fixed plate 221 due to its own weight and falls below. At the same time, the dust accumulated at the inner corner of the fixed plate 221 during polishing will also fall to the bottom of the equipment due to the force generated by the change in the shape of the fixed plate 221.
