Description

Technical Field

[0001] This utility model relates to the field of spiral blade grinding technology, specifically a processing and grinding device for spiral blades of conveying equipment. Background Technology

[0002] The helical blade is the main working part of a screw conveyor. It is primarily used for conveying materials with high viscosity and compressibility. This helical surface shape, while completing the conveying operation, also functions to stir and mix the materials. Screw conveyor blades come in three forms: solid helical surface, ribbon helical surface, and blade helical surface.

[0003] Literature review revealed that an existing patent (publication number: CN217433952U) discloses a processing and grinding device for paver auger blades, including a worktable; a fixing mechanism, including a fixing plate disposed above the worktable, a slide rail disposed above the worktable, an electric sliding plate disposed inside the slide rail, the electric sliding plate being movably connected to the slide rail, and a telescopic rod disposed above the electric sliding plate; and a protection mechanism, including a support plate disposed on one side of the worktable, and a cooling component disposed above the support plate, the cooling component being used to cool the auger blades.

[0004] Although the existing technology described above achieves the grinding of spiral blades, and the magnets on the lower side can separate iron filings and water during grinding, in actual use, the iron filings adsorbed on the magnet surface are not easy to collect. After the grinding work is completed, the iron filings on the magnet surface need to be manually cleaned and collected to facilitate subsequent secondary processing. This undoubtedly increases the workload of the workers and has poor practicality. In view of this, we propose a processing and grinding device for spiral blades of conveying equipment to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a processing and grinding device for spiral blades of conveying equipment, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a processing and grinding device for spiral blades of a conveying equipment, comprising a worktable, a spiral blade disposed on the upper side of the worktable, a first through groove extending to the upper and lower surfaces of the worktable, a first collection box fixedly connected to the lower surface of the worktable, a mounting frame fixedly connected inside the first collection box, a magnetic plate disposed inside the mounting frame, second through grooves disposed on both sides of the first collection box, second collection boxes fixedly connected to both sides of the first collection box, and a first guide groove disposed on the front surface of the worktable. A drive assembly is installed inside the guide groove. A transverse plate is slidably connected inside the first guide groove. A vertical plate is fixedly connected to the surface of the transverse plate. A grinding assembly is installed on the surface of the vertical plate. A second guide groove is opened on the inner wall of the first through groove. A reciprocating screw is rotatably connected inside the second guide groove. A reciprocating screw sleeve is threaded on the surface of the reciprocating screw. A connecting rod is fixedly connected to the surface of the reciprocating screw sleeve. A scraper is fixedly connected to the surface of the connecting rod. A third guide groove is opened on the rear surface of the worktable. An adjustment assembly is installed inside the third guide groove. A clamping assembly is installed on the upper side of the worktable.

[0007] By adopting the above technical solution, the scraper can be moved back and forth on the surface of the magnetic plate by driving the reciprocating screw to rotate through the drive component. This allows the magnetic plate to be cleaned during the grinding process of the spiral blades, eliminating the need for separate cleaning work afterward. It also facilitates the collection of iron filings produced during grinding, making it easier for subsequent secondary processing. This further improves the practicality and flexibility of the device and reduces the workload.

[0008] Preferably, the drive assembly includes a threaded rod rotatably connected inside the first guide groove. The transverse plate is threaded onto the outer surface of the threaded rod. The worktable has a cavity inside. The right ends of both the reciprocating screw and the threaded rod rotatably penetrate into the cavity and are rotatably connected to the inner wall of the cavity. A first motor is fixedly connected to the right side surface of the worktable. The output shaft of the first motor rotatably penetrates into the cavity and is fixedly connected to the threaded rod. A first gear is fitted at one end of the reciprocating screw inside the cavity, and a second gear is fitted at one end of the threaded rod inside the cavity. The first gear and the second gear are meshed together.

[0009] By adopting the above technical solution, the scraper moves synchronously during the movement of the grinding component through the setting of the drive component, thereby reducing the number of motors and reducing the cost of production and manufacturing.

[0010] Preferably, the adjusting assembly includes a bidirectional threaded rod, which is rotatably connected inside the third guide groove. A connecting plate is threaded onto each of the two opposite threads of the bidirectional threaded rod. An L-shaped fixing plate is fixedly connected to the surface of the connecting plate. The clamping assembly is set on the L-shaped fixing plate. A second motor is fixedly connected to the right side surface of the worktable. The output shaft of the second motor rotatably penetrates into the interior of the worktable and is fixedly connected to the bidirectional threaded rod.

[0011] By adopting the above technical solution, the position of the clamping component can be adjusted by the staff according to the actual work needs, which facilitates the fixing of spiral blades of different specifications, further improving the applicability of the device, making it more flexible and applicable.

[0012] Compared with the prior art, the present invention provides a processing and grinding device for spiral blades of conveying equipment, which has the following beneficial effects:

[0013] 1. The processing and grinding device for the spiral blades of this conveying equipment can achieve the reciprocating movement of the scraper on the surface of the magnetic plate by driving the reciprocating screw to rotate through the drive component.

It also facilitates the collection of iron filings produced during grinding, making it easier for subsequent secondary processing. This further improves the practicality and flexibility of the device and reduces the workload.

[0014] 2. The processing and grinding device for the spiral blades of this conveying equipment allows workers to adjust the position of the clamping components according to actual work needs through the setting of the adjustment components, thereby facilitating the fixing of spiral blades of different specifications, further improving the applicability of the device, and making it highly flexible and applicable.

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.

[0025] Please see Figures 1-6 This utility model provides a technical solution: a processing and grinding device for spiral blades of a conveying equipment, including a workbench 1, a spiral blade 2 arranged on the upper side of the workbench 1, a first through groove 3 extending to the upper and lower surfaces of the workbench 1 to facilitate the passage of cooling water and iron filings, a first collection box 4 for collecting cooling water fixedly connected to the lower surface of the workbench 1, a drain outlet provided on the surface of the first collection box 4, the first collection box 4 and the first through groove 3 connected, an installation frame 5 fixedly connected inside the first collection box 4, a magnetic plate 6 for collecting iron filings provided inside the installation frame 5, second through grooves 7 for facilitating the passage of iron filings on both sides of the first collection box 4, second collection boxes 8 for collecting iron filings fixedly connected to both sides of the first collection box 4, a cleaning hopper slidably connected inside the second collection box 8, the first collection box 4 and the second collection box 8 connected through the second through grooves 7, a first guide groove 9 for restricting and guiding the movement trajectory of the structure provided on the front surface of the workbench 1, a drive component for driving the structure to run provided inside the first guide groove 9.

[0026] The first guide groove 9 has a sliding connection inside a transverse plate 10 that provides support and connection. A vertical plate 11 is fixedly connected to the surface of the transverse plate 10. A grinding assembly 12 for grinding the spiral blade 2 is provided on the surface of the vertical plate 11. The grinding assembly 12 is an existing structure, and for details, please refer to the prior art with publication number CN217433952U. Its working principle is known to those skilled in the art, so it will not be described in detail here. The movement of the transverse plate 10 can drive the movement of the vertical plate 11. The movement of the grinding component 12 can drive the grinding work of the spiral blade 2. Subsequently, the grinding component 12 can be operated to grind the spiral blade 2. During the grinding process, the operator can spray cooling water through the external water spray pipe to cool the grinding component 12 and the spiral blade 2. The cooling water and debris will fall into the interior of the first collection box 4 through the first channel 3. At this time, the water will flow into the lower side of the first collection box 4 through the inclined surface of the mounting frame 5 and the magnetic plate 6, while the iron filings will be attracted by the magnetic plate 6.

[0027] The inner wall of the first through groove 3 is provided with a second guide groove 13 to facilitate the restriction and guidance of the structural movement trajectory. A reciprocating screw 14, which plays a transmission role, is rotatably connected inside the second guide groove 13. A reciprocating screw sleeve 15 is threaded on the surface of the reciprocating screw 14. The reciprocating screw sleeve 15 is slidably connected inside the second guide groove 13. The rotation of the reciprocating screw 14 can drive the reciprocating screw sleeve 15 to slide inside the second guide groove 13. A connecting rod 16, which plays a connecting role, is fixedly connected to the surface of the reciprocating screw sleeve 15. The movement of the reciprocating screw sleeve 15 can drive the movement of the connecting rod 16.

[0028] A scraper 17 for pushing iron filings on the surface of the magnetic plate 6 is fixedly connected to the surface of the connecting rod 16. The movement of the connecting rod 16 can drive the scraper 17 to move. At this time, the scraper 17 will slide on the surface of the mounting frame 5 and the magnetic plate 6. Finally, the scraper 17 will push the iron filings on the surface of the magnetic plate 6 to one side of the second through groove 7, and then collect the iron filings into the interior of the second collection box 8. The scraper 17 and the mounting frame 5 are in contact with the surface of the magnetic plate 6. A third guide groove 23 is provided on the rear surface of the worktable 1. An adjustment component is provided inside the third guide groove 23. A clamping component 27 for fixing the spiral blade 2 to be processed is provided on the upper side of the worktable 1. The clamping component 27 is an existing structure. For details, please refer to the prior art with publication number CN217433952U. Its working principle is known to those skilled in the art, so it will not be described in detail in this article.

[0029] In the above embodiments, the reciprocating lead screw 14 and the reciprocating lead screw sleeve 15 are both existing structures, specifically the reciprocating lead screw module with model number FSM0401-C3-1R-0085.

[0030] The drive assembly includes a threaded rod 18, which is rotatably connected inside the first guide groove 9. A transverse plate 10 is threaded onto the outer surface of the threaded rod 18. The rotation of the threaded rod 18 can drive the transverse plate 10 to slide inside the first guide groove 9. A cavity 19 is provided inside the worktable 1. The right ends of the reciprocating screw 14 and the threaded rod 18 are rotatably inserted into the cavity 19 and rotatably connected to the inner wall of the cavity 19. A first motor 20 for driving the structure is fixedly connected to the right side surface of the worktable 1. The output shaft of the first motor 20 rotatably inserts into the cavity 19 and is fixedly connected to the threaded rod 18. By starting the first motor 20, the rotation of the output shaft of the first motor 20 can drive the rotation of the threaded rod 18.

[0031] The reciprocating screw 14 is fitted with a first gear 21 inside the cavity 19, which serves as a transmission mechanism. The rotation of the first gear 21 drives the rotation of the reciprocating screw 14. The threaded rod 18 is fitted with a second gear 22 inside the cavity 19, which also serves as a transmission mechanism. The first gear 21 and the second gear 22 are meshed together. When the threaded rod 18 rotates, it drives the second gear 22 to rotate. Since the second gear 22 is meshed with the first gear 21, the first gear 21 will also rotate synchronously. The diameter of the second gear 22 is larger than the diameter of the first gear 21.

[0032] The adjusting assembly includes a bidirectional threaded rod 24, which is rotatably connected inside the third guide groove 23. Connecting plates 25, serving as supports and connections, are threaded onto both opposite threads of the bidirectional threaded rod 24. The connecting plates 25 are slidably connected inside the third guide groove 23. Rotation of the bidirectional threaded rod 24 causes the two connecting plates 25 to slide within the third guide groove 23. An L-shaped fixing plate 26 is fixedly connected to the surface of the connecting plate 25. A clamping assembly 27 is mounted on the L-shaped fixing plate 26. Movement of the connecting plate 25 causes the L-shaped fixing plate 26 to move. The movement of plate 26, through the movement of L-shaped fixed plate 26, drives the movement of clamping assembly 27, ultimately achieving the adjustment of the distance between the two clamping assemblies 27, thereby adapting to spiral blades 2 of different lengths. Both L-shaped fixed plate 26 and clamping assembly 27 are in contact with the upper surface of worktable 1. A second motor 28 is fixedly connected to the right side surface of worktable 1. The output shaft of the second motor 28 rotates through the interior of worktable 1 and is fixedly connected to bidirectional threaded rod 24. By starting the second motor 28, the rotation of the output shaft of the second motor 28 drives the rotation of bidirectional threaded rod 24.

[0033] Working principle:

[0034] When using the processing and grinding device for the spiral blades of this conveying equipment, the second motor 28 is started first. The rotation of the output shaft of the second motor 28 drives the rotation of the bidirectional threaded rod 24. The rotation of the bidirectional threaded rod 24 drives the two connecting plates 25 to slide inside the third guide groove 23. The movement of the connecting plates 25 drives the movement of the L-shaped fixing plate 26. The movement of the L-shaped fixing plate 26 drives the movement of the clamping assembly 27, ultimately adjusting the distance between the two clamping assemblies 27 to accommodate spiral blades 2 of different lengths. The spiral blade 2 to be processed is then fixed by the clamping assembly 27.

[0035] After the spiral blade 2 is fixed, the spiral blade 2 can be polished by operating the polishing assembly 12. During the polishing process, the staff can spray cooling water through the external water spray pipe to cool the polishing assembly 12 and the spiral blade 2. Subsequently, the cooling water and debris will fall into the interior of the first collection box 4 through the first channel 3. At this time, the water will flow into the lower side of the first collection box 4 through the inclined surface of the mounting frame 5 and the magnetic plate 6, while the iron filings will be attracted by the magnetic plate 6.

[0036] During the grinding process of the spiral blade 2, the first motor 20 is started. The rotation of the output shaft of the first motor 20 drives the rotation of the threaded rod 18. The rotation of the threaded rod 18 drives the transverse plate 10 to slide inside the first guide groove 9. The movement of the transverse plate 10 drives the movement of the vertical plate 11. The movement of the vertical plate 11 drives the movement of the grinding assembly 12, thereby realizing the grinding work of the spiral blade 2.

[0037] During the rotation of the threaded rod 18, the second gear 22 will be driven to rotate. Since the second gear 22 is meshed with the first gear 21, the first gear 21 will also rotate synchronously. The rotation of the first gear 21 will drive the rotation of the reciprocating screw 14. The rotation of the reciprocating screw 14 will drive the reciprocating screw sleeve 15 to slide inside the second guide groove 13. The movement of the reciprocating screw sleeve 15 will drive the movement of the connecting rod 16. The movement of the connecting rod 16 will drive the movement of the scraper 17. At this time, the scraper 17 will slide on the surface of the mounting frame 5 and the magnetic plate 6. Finally, the scraper 17 will push the iron filings on the surface of the magnetic plate 6 to one side of the second through groove 7. At the same time, since the scraper 17 has a certain height, it can more smoothly collect the iron filings into the interior of the second collection box 8.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
