Description

Technical Field

[0001] This utility model relates to the field of conveyor belt technology, specifically an automatic feeding device for stainless steel mesh. Background Technology

[0002] The automatic feeding device for stainless steel mesh is an automated conveying equipment designed for stainless steel mesh belts. This device is widely used in many core industries such as metal processing, filtration equipment, automobile manufacturing, electronic instruments, building decoration, and medical and food machinery. Through the coordinated operation of multiple systems, this device can realize the continuous and unmanned conveying of stainless steel mesh raw materials from raw material erection to processing station.

[0003] Existing automatic stainless steel mesh feeding devices are generally divided into three types. The first type is a mechanical transmission feeding device, which relies on a motor and uses mechanical structures such as gears, cams, and chains to convert rotational motion into linear conveying motion of the stainless steel mesh. The feeding step distance is controlled by mechanical limits or cam profiles. The second type is a pneumatic feeding device, which uses compressed air as power and uses a cylinder to push the gripper to clamp the stainless steel mesh. The linear feeding is achieved by extending and retracting the cylinder. The third type is a hydraulic feeding device, which uses hydraulic oil as power and uses a hydraulic cylinder to drive the feeding mechanism. It utilizes the high-pressure characteristics of the hydraulic system to achieve high-thrust conveying. This utility model mainly improves upon the first type.

[0004] First, the equipment typically uses a motor for continuous feeding, while downstream processes have fixed processing times. When the feeding speed consistently exceeds the downstream processing speed, materials accumulate rapidly in front of the processing station, forcing workers to stop feeding and manually clear them. If not intervened in time, the accumulated materials will be squeezed and deformed, or even cause the conveyor belt to jam due to excessive compression. Furthermore, some equipment requires processing of the materials on the conveyor belt during transportation, such as surface spraying, barcode scanning and positioning, and manual picking. Continuous transportation makes it difficult to process the materials, thus affecting the product qualification rate.

[0005] Secondly, the equipment height is usually fixed and can only adapt to the height requirements of a single process. However, when the production scenario changes and the height of upstream or downstream equipment changes, the fixed height of the original equipment will create a significant height difference with the new process. When materials fall from the lower upstream equipment outlet to the higher feeding equipment, they are prone to collision damage due to the drop difference. If the downstream process equipment is even higher, the feeding equipment will be insufficient in height, and the materials will need to be manually lifted before they can be transferred to the next process. This not only increases the labor intensity of workers but also reduces the efficiency of process connection. To adapt to the new height, the equipment support and mesh belt drive structure need to be completely disassembled, cut, and welded, which not only consumes a lot of downtime but also significantly increases the cost of production interruption.

[0006] Finally, the conveyor frame of the equipment is usually designed for flat conveying. When there is a height difference between the upstream and downstream equipment in special scenarios, the flat conveyor frame cannot form an inclined transition. The materials need to be manually moved from the upstream equipment to the downstream equipment. This not only increases the labor cost in the intermediate links, but also causes material accumulation due to the low efficiency of manual handling, which further affects the overall production rhythm. Especially in the case of heavy materials or mass production, manual handling may also cause safety risks such as worker bumps and material injuries.

[0007] Based on this, the present invention provides an automatic feeding device for stainless steel mesh to solve the above problems. Utility Model Content

[0008] In view of the above situation and to overcome the defects of the prior art, this utility model provides an automatic feeding device for stainless steel mesh. This utility model has a novel structure and ingenious design, and effectively solves the technical problems of the equipment being unable to feed intermittently, the equipment height being fixed, and the angle being non-adjustable.

[0009] An automatic feeding device for stainless steel mesh includes a conveyor frame. A drive roller is rotatably mounted on the left side of the conveyor frame, and a driven roller is rotatably mounted on the right side of the conveyor frame. The same mesh belt is fitted onto the drive roller and the driven roller. A rotating shaft is rotatably mounted on the left side of the conveyor frame, located next to the drive roller. A crank wheel is provided at one end of the rotating shaft, and a crank shaft is fixedly mounted on the crank wheel. A keyway is provided on the crank wheel. A sliding hole is provided at the front end of the rotating shaft, and a sliding groove is provided in the sliding hole. A drive shaft is slidably mounted in the sliding groove. Keys matching the sliding groove and the keyway are fixedly mounted at the front and rear ends of the drive shaft, respectively. A grooved wheel matching the crank wheel is fixedly mounted at the end of the drive roller, and a through groove matching the crank shaft is provided on the grooved wheel.

[0010] Preferably, a drive gear is fixedly mounted on the drive shaft, a push rod is fixedly mounted on the drive gear, a button is fixedly mounted at the end of the push rod, a driven gear capable of meshing with the drive gear is fixedly mounted on the drive roller, and a protective cover fixedly mounted on the conveyor frame is installed on the outside of the drive gear and the driven gear.

[0011] Preferably, the lower end of the conveyor frame is hinged with multiple upper legs, and each upper leg is fitted with a lower leg. The same fixed plate is fixedly installed between two lower legs, and multiple support plates are fixedly installed on the fixed plate. The same rotating rod is installed on every two support plates. The front and rear ends of the rotating rod are fixedly installed with connecting rods, and transmission rods are slidably installed inside the connecting rods. The end of the transmission rod is hinged with a hinge block fixedly installed at the lower end of the upper leg, and a rectangular groove is opened on the lower leg outside the hinge block.

[0012] Preferably, a worm gear is rotatably mounted in the center of the fixed plate, a handle is fixedly mounted at the end of the worm gear, and worm wheels capable of meshing with the worm gear are mounted on both sides of the worm gear. The worm wheels are fixedly mounted on the rotating rod, and an adjustment groove is provided on the support plate outside the rotating rod.

[0013] Preferably, each of the support plates is fixedly installed with a limiting plate, each limiting plate is fixedly installed with an installation cylinder, each installation cylinder is slidably installed with a push rod, each push rod is fitted with a spring fixedly installed inside the installation cylinder, each push rod is fixedly installed with a top plate at its end, and each top plate is fixedly installed with a limiting ring matching the rotating rod.

[0015] Preferably, one end of the rotating shaft is connected to a motor that is fixedly mounted on the conveyor frame, and the motor is connected to a power supply and a controller.

[0016] The present invention has the following technical effects.

[0017] 1. By incorporating a drive shaft, crank wheel, and grooved wheel, this utility model allows for intermittent feeding when switching the stainless steel mesh feeding mode. This is achieved by intermittently feeding through the keyway on the drive shaft and the keyway on the crank wheel. The drive shaft drives the active gear and the driven gear to mesh and achieve continuous feeding, thus completing the flexible switching of feeding modes and significantly improving the adaptability of the equipment to different processing requirements.

[0018] 2. By incorporating structures such as an upper support leg, a lower support leg, a worm gear, and a worm wheel, this utility model allows for height adjustment of the conveyor frame when adapting to processing equipment of different heights. The worm gear drives the worm wheel to rotate the rotating rod, and the connecting rod drives the transmission rod to make the upper support leg slide within the lower support leg. This significantly reduces the equipment's limitations on the height of the processing equipment and effectively avoids problems such as misalignment of stainless steel mesh feeding or inability to connect the processing flow due to the fixed height of the equipment failing to match the processing requirements.

[0019] 3. By incorporating structures such as adjustment grooves, limiting plates, springs, and limiting rings, this utility model allows for adjustments to the conveyor frame's tilt angle to accommodate inclined processing equipment or uneven ground. First, the rotating rod is pushed along the adjustment groove on the support plate, disengaging the worm gear on one side from the worm. Then, the worm is rotated to drive the worm gear on the other side, causing the corresponding rotating rod to rotate. Through a connecting rod, the transmission rod drives the upper support leg on one side to slide and rise within the lower support leg, thus completing the adjustment of the conveyor frame angle. This effectively solves the technical problem of the conveyor frame's non-adjustable angle. Attached Figure Description

Detailed Implementation

[0028] The foregoing and other technical contents, features and effects of this utility model are described in conjunction with the appendix below. Figures 1 to 5 The detailed description of the embodiments will make this clear. All references to the following embodiments are made with reference to the accompanying drawings.

[0029] Exemplary embodiments of the present invention will now be described with reference to the accompanying drawings.

[0030] This utility model relates to an automatic feeding device for stainless steel mesh, comprising a conveyor frame 1, which is generally rectangular in shape. A drive roller 2 is rotatably mounted on the left side of the conveyor frame 1, with its front end extending through and beyond the outer side of the conveyor frame 1. A driven roller 3 is rotatably mounted on the right side of the conveyor frame 1. The driven roller 3 has the same structure as the drive roller 2, and their axes are parallel and on the same horizontal plane. The same mesh belt 4, made of stainless steel, is fitted onto both the drive roller 2 and the driven roller 3. A rotating shaft 5, cylindrical in shape, is rotatably mounted on the left side of the conveyor frame 1, with a crank wheel 6 at one end. A crankshaft 7 is fixedly mounted on the crank wheel 6. The inner ring of the crank wheel 6 has a keyway 8 along the axial direction. The front end of the rotating shaft 5 has a sliding hole 9. A groove 10 is formed in the sliding hole 9. The drive shaft 11 is slidably installed in the groove 10. A baffle is fixedly installed in the sliding hole 9 at the end of the groove 10 to limit the drive shaft 11 so that it will not disengage from the sliding hole 9. Key bars 12 that match the groove 10 and the keyway 8 are fixedly installed at intervals at the front and rear ends of the drive shaft 11. The key bar 12 at the front end slides in the groove 10 in the sliding hole 9, and the key bar 12 at the rear end can slide into the keyway 8 on the crank wheel 6. The end of the drive roller 2 is fixedly installed with a grooved wheel 13 that matches the crank wheel 6. A through groove 14 that matches the crank shaft 7 is formed on the grooved wheel 13.

[0031] In practical use, when intermittent feeding of materials is required, the rotating shaft 5 starts to rotate. When the rotating shaft 5 rotates, it drives the drive shaft 11 to rotate through the key bar 12 at the front end of the drive shaft 11 and the sliding groove 10 in the sliding hole 9. The key bar 12 on the drive shaft 11 can slide into the key groove 8 on the crank wheel 6. At this time, the torque of the rotating shaft 5 is transmitted to the crank wheel 6 through the key bar 12, causing the crank wheel 6 to rotate together with the rotating shaft 5. When the crank wheel 6 rotates, it drives the crank shaft 7 to periodically embed into the through groove 14 of the groove wheel 13, driving the groove wheel 13 to rotate intermittently, which in turn drives the drive roller 2 to rotate intermittently, ultimately realizing the intermittent feeding of the mesh belt 4. This process effectively solves the technical problem that the equipment cannot feed intermittently.

[0032] As an example, a drive gear 15 is fixedly mounted on the drive shaft 11, and a push rod 16 is fixedly mounted on the drive gear 15. The push rod 16 is cylindrical, and a button 17 is fixedly mounted at the end of the push rod 16 to facilitate pushing the drive shaft 11 to slide in the sliding hole 9, so as to realize the insertion or disengagement of the key bar 12 at the rear end of the drive shaft 11 and the keyway 8 of the crank wheel 6. A driven gear 18 that can mesh with the drive gear 15 is fixedly mounted on the drive roller 2. A protective cover 19 fixedly mounted on the conveyor frame 1 is installed on the outside of the drive gear 15 and the driven gear 18 to prevent impurities from being drawn into the drive gear 15 and the driven gear 18 during the meshing transmission process.

[0033] In practical use, when it is necessary to switch the transmission state, the operator can hold the button 17 at the end of the push rod 16 and pull the drive shaft 11 to slide backward. At this time, the drive shaft 11 will slide along the sliding hole 9 and the slide groove 10 of the rotating shaft 5. Since the key bar 12 at the rear end of the drive shaft 11 was originally embedded in the key groove 8 of the crank wheel 6, as the drive shaft 11 moves backward, the rear key bar 12 will gradually disengage from the key groove 8 until it is completely out of the key groove 8. At this time, the front key bar 12 is not disengaged from the slide groove 10. Simultaneously, the drive shaft 11 will move backward with the central drive gear 15. The drive gear 15 gradually approaches the driven gear 18 on the drive roller 2. When the drive shaft 11 When the baffle in the sliding hole 9 is limited, the driving gear 15 and the driven gear 18 are fully meshed. At this time, the rotating shaft 5 transmits power to the driving shaft 11 through the key bar 12 embedded in the sliding groove 10 at the front end of the drive shaft 11, so that the drive shaft 11 rotates synchronously with the rotating shaft 5. The rotation of the drive shaft 11 will directly drive the driving gear 15 in the middle to rotate. Since the driving gear 15 and the driven gear 18 are in a meshing state, the driving gear 15 transmits power to the driven gear 18 through tooth surface meshing. The driven gear 18 is fixedly connected to the driving roller 2, and finally drives the driving roller 2 to rotate synchronously. This process completes the switching between intermittent motion and continuous motion, so that different conveying states can be selected for different conveying conditions.

[0034] As one embodiment, multiple upper support legs 20 are hinged at the four corners of the lower end of the conveyor frame 1. Each upper support leg 20 is generally rectangular in shape, and a matching lower support leg 21 is fitted onto the outer side of each upper support leg 20. The lower support leg 21 is also rectangular in shape, and an axial cavity is formed inside the lower support leg 21, allowing the upper support leg 20 to slide axially within the cavity of the lower support leg 21. A common fixing plate 22 is fixedly installed between two lower support legs 21. Multiple support plates 23 are vertically fixedly installed on the surface of the fixing plate 22. The same rotating rod 24 is installed on the two support plates 23. The rotating rod 24 is cylindrical in shape. Connecting rods 25 are fixedly installed on the rotating rod 24 near the front and rear ends. The connecting rods 25 have a hollow cavity design. A transmission rod 26 is slidably installed inside the connecting rods 25. A hinge block 27 is hinged to the end of the transmission rod 26 and fixedly installed on the lower end of the upper support leg 20. A rectangular groove 28 is opened on the outside of the hinge block 27 and placed on the lower support leg 21. This provides sliding space for the hinge block 27 and also guides the hinge block 27.

[0035] In practical use, when it is necessary to adjust the height of the conveyor frame 1, the operator can rotate the rotating rod 24. The rotating rod 24 drives the connecting rods 25 at both ends to rotate synchronously. When the connecting rods 25 rotate, they will push the internal transmission rod 26 to slide along the cavity of the connecting rod 25. The transmission rod 26 drives the upper support leg 20 to slide axially in the cavity of the lower support leg 21 through the hinge block 27. If the rotating rod 24 rotates in the forward direction, the connecting rod 25 will push the transmission rod 26 to extend outward, thereby driving the upper support leg 20 to slide upward, so that the height of the conveyor frame 1 is raised. If the rotating rod 24 rotates in the reverse direction, the connecting rod 25 will pull the transmission rod 26 to retract inward, driving the upper support leg 20 to slide downward, so that the height of the conveyor frame 1 is lowered. This process completes the adjustment of the height of the equipment, effectively solving the technical problem of fixing the height of the equipment.

[0036] As one embodiment, a worm gear 29 is rotatably mounted in the center of the fixed plate 22. One end of the worm gear 29 extends to the bottom of the fixed plate 22, and a handle 30 is fixedly mounted at the end of the worm gear 29. Worm wheels 31 that can mesh with the worm gear 29 are mounted on both sides of the worm gear 29. The worm wheels 31 are fixedly mounted on the rotating rod 24, so that when the worm gear 29 rotates, it can synchronously drive the worm wheels 31 on both sides to rotate, thereby driving the rotating rods 24 on both sides to rotate synchronously. The rotating rod 24 has an adjustment groove 32 placed on the support plate 23, and the transmission rod 26 can slide along the adjustment groove 32.

[0037] In practical use, when the height of the conveyor frame 1 needs to be adjusted, the operator only needs to hold the handle 30 and rotate the worm 29. The worm 29 will drive the worm wheels 31 on both sides to rotate synchronously, ensuring that the two rotating rods 24 can adjust the two connecting rods 25 upwards or downwards. The worm wheels 31 drive the corresponding rotating rods 24 to rotate, and the rotating rods 24 drive the connecting rods 25 to pull the transmission rods 26 to retract, thereby causing the upper support leg 20 to slide downwards, and the height of the conveyor frame 1 to decrease. If the handle 30 is rotated in the opposite direction, the worm 29 drives the worm wheels 31 on both sides to rotate synchronously in the opposite direction. The worm wheels 31 drive the rotating rods 24 to rotate in the opposite direction, and the connecting rods 25 push the transmission rods 26 to extend, causing the upper support leg 20 to slide upwards, and the height of the conveyor frame 1 to increase. Because the worm 29 and worm wheel 31 transmission has a self-locking property, after the handle 30 is stopped, the worm 29 and worm wheel 31 will maintain the current meshing state and will not cause the worm wheel 31 to rotate in the opposite direction due to the weight of the conveyor frame 1, thereby ensuring the position of the upper support leg 20. The height of the conveyor frame 1 is stable and will not shift on its own. When it is necessary to adjust the angle of the conveyor frame 1, the rotating rod 24 can be slightly pushed radially along the adjustment groove 32, so that the rotating rod 24 drives the worm wheel 31 fixed on it to move laterally until either worm wheel 31 disengages from the worm 29. At this time, the worm 29 is rotated. Since one worm wheel 31 has disengaged, the worm 29 can only drive the other worm wheel 31 to rotate. The driven worm wheel 31 drives the corresponding rotating rod 24 to rotate. The rotating rod 24 pushes the corresponding transmission rod 26 to extend outward through the connecting rod 25, which in turn drives the upper support leg 20 on one side to slide upward along the cavity of the lower support leg 21. The extension length of the upper support leg 20 on one side increases, and finally the height of the conveyor frame 1 is raised. Conversely, the other side is raised. The operator can adjust the tilt angle of the two sides according to the actual situation. This process completes the control of the tilt angle of the conveyor frame 1, effectively solving the technical problem of the non-adjustable conveying angle of the equipment.

[0038] As an example, each support plate 23 is fixedly mounted with a limiting plate 33, and each limiting plate 33 is fixedly mounted with an mounting cylinder 34. The mounting cylinder 34 is hollow inside, and each mounting cylinder 34 has a push rod 35 slidably mounted inside. The push rod 35 is cylindrical in shape, with one end extending to the outside of the mounting cylinder 34 towards the rotating rod 24. Each push rod 35 is fitted with a spring 36 fixedly mounted inside the mounting cylinder 34, and each push rod 35 has a top plate 37 fixedly mounted at the end. One end of the spring 36 is fixed to the bottom of the mounting cylinder 34, and the other end abuts against the top plate 37. The spring 36 is initially in a slightly compressed state, which can always apply a thrust towards the rotating rod 24 to the push rod 35. Each top plate 37 is fixedly mounted with a limiting ring 38 that matches the rotating rod 24. The inner diameter of the limiting ring 38 is the same as the outer diameter of the rotating rod 24.

[0039] In practical use, after the rotating rod 24 stops rotating in the adjusting groove 32, that is, after the angle of the conveyor frame 1 is adjusted, the spring 36 in the mounting cylinder 34 will push the top plate 37 and the limiting ring 38 to move towards the rotating rod 24, so that the limiting ring 38 is tightly fitted on the outside of the rotating rod 24. Through the continuous thrust of the spring 36, the rotating rod 24 is pushed to the edge of the adjusting groove 32. At this time, the worm gear 31 and the worm 29 are re-meshed. This process avoids the rotating rod 24 from shifting due to vibration during the operation of the device, thereby preventing the meshing state of the worm gear 31 and the worm 29 from changing.

[0040] As an example, the upper support leg 20 has scale lines 39 on its surface, making it easier to observe the height of the conveyor frame 1 when it is raised and lowered.

[0041] As one embodiment, one end of the rotating shaft 5 is connected to a motor 40 that is fixedly mounted on the conveyor frame 1, and the motor 40 is connected to a power supply and a controller.

[0042] The working principle of this utility model is as follows: When using the automatic stainless steel mesh feeding device, first turn on the power supply of the motor 40. The motor 40 drives the rotating shaft 5 to rotate. If intermittent feeding is required, the rotating shaft 5 drives the drive shaft 11 to rotate via the key bar 12 at the front end of the drive shaft 11. The key bar 12 at the rear end of the drive shaft 11 is embedded in the keyway 8 of the crank wheel 6, so that the crank wheel 6 rotates and drives the crank shaft 7 to periodically engage with the groove 14 of the groove wheel 13 of the drive roller 2. The drive roller 2 rotates intermittently, thereby feeding the stainless steel mesh belt 4 intermittently. If it is necessary to switch to continuous feeding, hold the push rod 16 and pull the button 17 at the end to pull the drive shaft 11, so that it slides backward along the sliding hole 9 and the sliding groove 10 of the rotating shaft 5. The key bar 12 at the rear end of the drive shaft 11 disengages from the keyway 8 of the crank wheel 6. At the same time, the drive gear 15 and the driven gear 18 on the drive roller 2 are fully meshed. The torque of the rotating shaft 5 drives the drive roller 2 to rotate continuously via the drive shaft 11 and the gear transmission. When adjustment is required... To adjust the height, rotate the handle 30 of the worm gear 29 centered on the fixed plate 22. The worm gear 29 drives the worm wheels 31 on both sides to rotate synchronously. The worm wheels 31 drive the rotating rod 24 to rotate. The connecting rods 25 at both ends of the rotating rod 24 push or pull the transmission rod 26, which drives the upper support leg 20 to slide in the lower support leg 21 through the hinge block 27. At the same time, the height can be determined by referring to the scale line 39 of the upper support leg 20, and the height is kept stable by the self-locking of the worm gear 29 and worm wheel 31. If the angle needs to be adjusted, push the rotating rod 24 along the adjustment groove 32 of the support plate 23 to disengage the worm wheel 31 on one side from the worm gear 29. Then rotate the worm gear 29 to drive only the worm wheel 31 on the other side and the rotating rod 24, thereby driving the upper support leg 20 on one side to rise and fall to achieve angle adjustment. After adjustment, the spring 36 in the mounting cylinder 34 on the limit plate 33 of the support plate 23 will push the top rod 35 and the limit ring 38 to fit tightly against the rotating rod 24 to prevent vibration from causing the parts to shift and to ensure stable operation of the device.

[0043] The present invention has the following technical effects.

[0044] 1. By incorporating a drive shaft 11, a crank wheel 6, and a grooved wheel 13, this utility model allows for intermittent feeding when switching the stainless steel mesh feeding mode. This is achieved by intermittently feeding the key bar 12 on the drive shaft 11 and engaging or disengaging it with the keyway 8 of the crank wheel 6. The drive shaft 11 drives the active gear 15 to mesh with the driven gear 18 to achieve continuous feeding, thus completing the flexible switching of the feeding mode and significantly improving the adaptability of the equipment to different processing requirements.

[0045] 2. By incorporating structures such as an upper support leg 20, a lower support leg 21, a worm gear 29, and a worm wheel 31, this utility model allows for height adjustment of the conveyor frame 1 when adapting to processing equipment of different heights. The worm gear 29 drives the worm wheel 31 to rotate the rotating rod 24, and the connecting rod 25 drives the transmission rod 26 to make the upper support leg 20 slide within the lower support leg 21. This significantly reduces the equipment's limitations on the height of the processing equipment and effectively avoids problems such as misalignment of stainless steel mesh feeding or inability to connect the processing flow due to the fixed height of the equipment failing to match the processing requirements.

[0046] 3. By incorporating structures such as the adjustment groove 32, the limiting plate 33, the spring 36, and the limiting ring 38, this utility model allows for the adjustment of the tilt angle of the conveyor frame 1 to accommodate tilted processing equipment or uneven ground. First, the rotating rod 24 is pushed along the adjustment groove 32 on the support plate 23, causing the worm gear 31 on one side to disengage from the worm 29. Then, the worm 29 is rotated to drive the worm gear 31 on the other side, which in turn drives the corresponding rotating rod 24 to rotate. Through the connecting rod 25, the transmission rod 26 is driven to allow the upper support leg 20 on one side to slide and rise within the lower support leg 21, thus completing the angle adjustment of the conveyor frame 1. This effectively solves the technical problem of the non-adjustable angle of the conveyor frame 1.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
