Description

Technical Field

[0001] This utility model relates to the field of surface grinding technology, specifically a surface grinding machine with a feeding mechanism. Background Technology

[0002] In the field of machining, surface grinders are key equipment that uses rotating grinding wheels to grind workpieces to achieve high-precision flatness requirements. Their level of automation directly affects processing efficiency and quality. However, some existing surface grinders face significant technical bottlenecks in practical applications, such as: Taking a surface grinder with application number CN202421477992.2 as an example, the upper end of the vacuum tube of the equipment is provided with a baffle, and the lower end of the vacuum tube arranged along the length of the support plate is connected to a control tube located in the support plate. An air pump is installed on the control tube to reduce the adverse effects on the processing quality. However, its core deficiency lies in the lack of a material loading and unloading system, which has led to a series of problems that restrict production efficiency: Without automated loading and unloading mechanisms, operators need to be involved in the entire workpiece flow process: within a single processing cycle, they need to complete multiple processes such as moving the workpiece from the waiting area to the machine tool table, manually clamping and positioning it, disassembling it after processing, and transferring it to the finished product area. Utility Model Content

[0003] The purpose of this utility model is to provide a surface grinder with a loading mechanism to solve the problem mentioned in the background art that existing equipment on the market does not have a loading and unloading mechanism, and in actual use, the workpiece needs to be placed manually, which is not only time-consuming and labor-intensive, but also inefficient and has limited accuracy.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a surface grinder with a feeding mechanism, comprising a support frame, a feeding frame, a discharging frame, a grinding disc, and a second drive roller; A conveying mechanism is provided on the side of the support frame. The conveying mechanism includes a third motor, a first tensioning frame, a second tensioning frame, a limiting frame, a spring, a conveyor belt, a first drive roller, and a second drive roller. The first tensioning frame is installed on one side of the limiting frame, and the second tensioning frame is installed on the other side of the limiting frame. A spring is installed between the second tensioning frame and the first tensioning frame. The first drive roller and the second drive roller are respectively installed above the first tensioning frame and the second tensioning frame. The conveyor belt is fitted on the outside of the first drive roller and the second drive roller. The third motor is installed below the second drive roller.

[0005] As a preferred technical solution of this utility model, the side of the support frame is connected to the feeding frame, and the feeding frame has an upward opening structure. The support frame and the discharge frame are connected at the parallel position of the feeding frame. The discharge frame has a downward opening structure, and both the discharge frame and the feeding frame have U-shaped internal structures. Circular notches are opened at the opposite positions of the discharge frame and the feeding frame. The above technical solution features an upward-opening feed rack connected to the side of the support frame, which facilitates operators in quickly placing materials onto the conveyor belt and reduces space constraints during loading. Both the feed rack and the parallel discharge rack have U-shaped internal structures with circular openings at opposite positions. The discharge rack has a downward-opening structure, allowing the processed materials to automatically slide out using gravity. This structural design creates a continuous conveyor path for materials from feeding to discharging, shortening the material's movement distance within the equipment and effectively improving overall processing efficiency.

[0006] As a preferred technical solution of this utility model, the left side of the support frame is connected to the drainage channel, the drainage channel is an L-shaped water channel, and the material tray is rotatably connected inside the support frame. The surface of the material tray is provided with material slots, and there are eight material slots evenly arranged. The bottom of the material tray is fixedly connected to the output shaft of the third motor, and the third motor is fixedly connected to the bottom surface of the support frame. Using the above technical solution, the drainage channel connected to the left side of the support frame is an L-shaped water channel, which can quickly collect wastewater and debris generated during grinding. Its L-shaped structure can naturally filter large particles of impurities by redirecting the water flow, reducing the risk of drainage pipe blockage. The surface of the rotating material tray inside the support frame has 8 evenly arranged material slots, which can simultaneously carry multiple workpieces to achieve "multi-station synchronous processing". Compared with single-station processing, the efficiency is increased by about 8 times. The material tray is fixedly connected to the output shaft of the third motor. The motor drives the material tray to rotate at a uniform speed, so that the workpieces pass under the grinding disc in sequence, ensuring the continuity and consistency of the processing rhythm and avoiding processing fluctuations caused by manual feeding.

[0007] As a preferred technical solution of this utility model, the side of the support frame is fixedly connected to the support arm, the lower side of the support arm is connected to a first motor, the upper output shaft of the first motor is fixedly connected to a lead screw, the upper surface of the first motor is fixedly connected to a guide rod, and the support arm is slidably connected to the support arm. The other side of the support arm is fixedly connected to a second motor, and the lower output shaft of the second motor is connected to the grinding disc. Using the above technical solution, a first motor is connected to the lower side of the support arm fixed on the side of the support frame. Its output shaft is fixedly connected to the lead screw. The motor can drive the lead screw to rotate to precisely control the up and down movement of the support arm, realizing stepless adjustment of the distance between the grinding disc and the material tray, which is suitable for grinding workpieces of different thicknesses. The guide rod on the upper surface of the first motor is slidably connected to the support arm to provide stable guidance for the movement of the support arm, avoid the grinding disc from shifting in the vertical direction, and ensure uniform distribution of grinding pressure. The second motor on the other side of the support arm directly drives the grinding disc to rotate at high speed, providing sufficient grinding force while reducing the problem of uneven surface texture of the workpiece caused by speed fluctuation through constant speed control of the motor.

[0008] As a preferred technical solution of this utility model, the feeding frame is fixedly connected to the side of the first tensioning frame, the first tensioning frame is slidably connected to one end of the limiting frame, and the limiting frame is an I-shaped structure. The other end of the limiting frame is slidably connected to the second tensioning frame. A pair of springs are sandwiched between the second tensioning frame and the first tensioning frame. The first driving roller is rotatably connected above the first tensioning frame, and the second driving roller is rotatably connected above the second tensioning frame. The second driving roller is fixedly connected to the output shaft of the third motor. Using the above technical solution, the first tensioning frame fixed on the side of the feed rack is slidably connected to one end of the limiting frame, and the other end of the limiting frame is slidably connected to the second tensioning frame. The spring sandwiched between the two can automatically compensate for the slack of the conveyor belt caused by long-term use through elastic force, maintain the tension of the conveyor belt, and avoid material conveying stagnation or positional deviation due to slippage. The limiting frame adopts an I-shaped structure to provide a horizontal sliding track for the first tensioning frame and the second tensioning frame, prevent the first drive roller and the second drive roller from tilting during the tensioning process, and ensure the straightness of the conveyor belt. The third motor directly drives the second drive roller, reducing energy loss in the power transmission link and enabling the conveyor belt to obtain a stable driving force.

[0009] Compared with the prior art, the beneficial effects of this utility model are: 1. The feeding rack connected to the side of the support frame has an upward opening structure, which facilitates the loading of materials. Its parallel position is connected to the downward opening discharge rack. Both of them have U-shaped structures inside and circular notches are opened at opposite positions.

[0012] 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.

[0013] Please see Figures 1-5 The present invention provides a surface grinder with a feeding mechanism, comprising a support frame 1, a feeding frame 2, a discharging frame 3, a grinding disc 4, a drainage trough 5, a first motor 6, a guide rod 7, a lead screw 8, a conveyor belt 9, a support arm 10, a second motor 11, a third motor 12, a material placement trough 13, a material placement tray 14, a first tensioning frame 15, a second tensioning frame 16, a limiting frame 17, a spring 18, a first drive roller 19, and a second drive roller 20. The side of the support frame 1 is connected to the feeding frame 2, and the feeding frame 2 has an upward opening structure. The support frame 1 is connected to the discharge frame 3 at a parallel position to the feeding frame 2. The discharge frame 3 has a downward opening structure, and both the discharge frame 3 and the feeding frame 2 have U-shaped internal structures. The discharge frame 3 and the feeding frame 2 have circular notches facing each other. The upward opening structure of the feeding frame 2 connected to the side of the support frame 1 makes it easy for operators to quickly place materials on the conveyor belt 9, reducing the limitation of the feeding space. The internal structures of the feeding frame 2 and the downward opening discharge frame 3 are both U-shaped. The design of the circular notches facing each other allows the processed materials to automatically slide off and be discharged by gravity, forming a continuous production line transmission path, shortening the movement distance of materials in the equipment, and effectively improving the overall processing efficiency. The left side of the support frame 1 is connected to the drainage channel 5, which is an L-shaped water channel. The support frame 1 is rotatably connected to the material tray 14. The surface of the material tray 14 has eight material slots 13 evenly arranged. The bottom of the material tray 14 is fixedly connected to the output shaft of the third motor 12. The third motor 12 is fixedly connected to the bottom surface of the support frame 1. The L-shaped drainage channel 5 connected to the left side of the support frame 1 can quickly collect wastewater and debris generated during grinding. Its L-shaped structure naturally filters large particles of impurities by redirecting the water flow, reducing the risk of drainage pipe blockage. The eight evenly arranged material slots 13 on the surface of the material tray 14 rotatably connected to the support frame 1 can simultaneously carry multiple workpieces to achieve "multi-station synchronous processing". Compared with single-station processing, the efficiency is increased by about 8 times. The material tray 14 is driven to rotate at a constant speed by the third motor 12, so that the workpieces pass under the grinding disc 4 in sequence, ensuring the continuity and consistency of the processing rhythm and avoiding processing fluctuations caused by manual feeding. The support frame 1 is fixedly connected to the support arm 10 on one side. The first motor 6 is connected to the lower side of one side of the support arm 10. The output shaft of the first motor 6 is fixedly connected to the lead screw 8. The guide rod 7 is fixedly connected to the upper surface of the first motor 6. The support arm 10 is slidably connected to the support arm 10. The second motor 11 is fixedly connected to the other side of the support arm 10. The output shaft of the second motor 11 is connected to the grinding disc 4. The support arm 10 fixed to the side of the support frame 1 can be precisely controlled to move up and down by the combination of the first motor 6 and the lead screw 8 on one side. This allows for stepless adjustment of the distance between the grinding disc 4 and the material tray 14, which is suitable for grinding workpieces of different thicknesses. The sliding connection between the guide rod 7 on the upper surface of the first motor 6 and the support arm 10 provides stable guidance for the movement of the support arm 10, preventing the grinding disc 4 from shifting vertically and ensuring uniform distribution of grinding pressure. The second motor 11 on the other side directly drives the grinding disc 4 to rotate at high speed. While providing sufficient grinding force, the constant speed control of the motor reduces the problem of uneven surface texture of the workpiece caused by speed fluctuations, ensuring processing accuracy. The first tensioning frame 15 is fixedly connected to the side of the feeding frame 2. The first tensioning frame 15 is slidably connected to one end of the limiting frame 17, and the limiting frame 17 has an I-shaped structure. The other end of the limiting frame 17 is slidably connected to the second tensioning frame 16. A pair of springs 18 are sandwiched between the second tensioning frame 16 and the first tensioning frame 15. The first drive roller 19 is rotatably connected above the first tensioning frame 15. The second drive roller 20 is rotatably connected above the second tensioning frame 16. The second drive roller 20 is fixedly connected to the output shaft of the third motor 12. The spring 18 sandwiched between the first tensioning frame 15 fixed on the side of the feed frame 2 and the second tensioning frame 16 slidably connected at both ends of the limiting frame 17 can automatically compensate for the slack that the conveyor belt 9 will develop after long-term use through elastic force, maintain tension, and avoid slippage that could cause material conveying to stop or shift position. The I-shaped limiting frame 17 provides a horizontal sliding track for the tensioning frame to prevent the first drive roller 19 and the second drive roller 20 from tilting during the tensioning process, ensuring the straightness of the conveyor belt 9. At the same time, the third motor 12 directly drives the second drive roller 20, reducing power transmission energy loss and enabling the conveyor belt 9 to obtain a stable driving force, which is suitable for continuous and efficient conveying of materials with high density such as graphite.

[0014] Working principle: When using a surface grinder with a feeding mechanism, the third motor 12 starts and drives the second drive roller 20 to rotate. The friction between the conveyor belt 9 and the first drive roller 19 and the second drive roller 20 drives the conveyor belt 9 to run. The operator places the material to be processed into the upward-opening feed rack 2. The material moves towards the support frame 1 along with the conveyor belt 9. During this process, the spring 18 provides elastic support to the first tension frame 15 and the second tension frame 16 through the limit frame 17, continuously compensating for the slack of the conveyor belt 9, ensuring that there is no slippage during the conveying process, and realizing stable feeding of materials. The material is conveyed by the conveyor belt 9 to the support frame 1 and falls into the material troughs 13 evenly arranged on the surface of the material tray 14. The third motor 12 synchronously drives the material tray 14 to rotate at a constant speed, so that the material in the material trough 13 moves sequentially to the ground surface 4 directly below. At this time, the second motor 11 drives the grinding surface 4 to rotate at high speed. At the same time, the first motor 6 drives the support arm 10 to move up and down through the lead screw 8, precisely adjusting the distance between the grinding surface 4 and the material tray 14. The guide rod 7 is slidably connected to the support arm 10 to ensure that the support arm 10 moves without deviation, so that the grinding pressure is evenly distributed and the surface of the material is precisely ground. When the feeding tray 14 rotates to the corresponding position of the discharge rack 3, the processed material falls from the feeding trough 13 and is discharged by gravity through the downward-opening discharge rack 3. Both the discharge rack 3 and the feeding rack 2 are U-shaped structures with circular notches at opposite positions, which can guide the material to be transported along a fixed path to avoid accumulation. At the same time, the wastewater and debris generated during the grinding process are collected through the L-shaped drainage trough 5 on the left side of the support frame 1. The L-shaped water channel filters large particles of impurities naturally by turning the water flow. The wastewater is discharged from the equipment through the pipe, reducing the risk of drainage pipe blockage. The third motor 12 simultaneously drives the conveyor belt 9 and the material tray 14, ensuring precise matching between material feeding and the rotation rhythm of the processing station. For example, for every piece of material conveyed by the conveyor belt 9, the material tray 14 rotates one station, forming an automated assembly line operation. The spring 18 cooperates with the I-shaped limit frame 17 to ensure that the tension of the conveyor belt 9 is constant. The third motor 12 directly drives the second drive roller 20, reducing power transmission loss and making it suitable for continuous conveying of materials with high density such as graphite. In addition, the combination of the lead screw 8 and the guide rod 7 enables precise adjustment of the vertical position of the grinding disc 4, and the constant speed control of the second motor 11 ensures stable grinding speed and guarantees processing accuracy.
