Description

Technical Field

[0001] This utility model relates to the field of filter end cap processing technology, specifically to a filter end cap tapping machine. Background Technology

[0002] The filter end cap is an important component of the filter, mainly serving to seal both ends of the filter media and support the filter media. The middle of the filter end cap usually needs to be threaded, so a tapping machine is required to process the end cap.

[0003] Chinese invention patent publication number "CN104439558B" discloses a multi-station tapping machine for filter thread covers. The main motor is fixed to the top plate of the machine housing. A drive shaft, which works with the main motor, extends into a gearbox containing a gear train. The lower end of the drive shaft connects to the beginning of the gear train. Taps are coaxially connected to the ends of the gear train. A carrying cylinder is located below the taps, with several positioning plates on it. A horizontal connecting plate is located inside the machine housing. A servo motor is fixed to the connecting plate and engages with the screw of a lifting lead screw. The nut of the lifting lead screw is fixedly connected to the gearbox. A first balancing cylinder is fixed to the top plate of the machine housing and fixedly connected to the connecting plate. A stroke cylinder is fixed to the top plate of the machine housing and fixedly connected to the connecting plate. A second balancing cylinder is fixed to the connecting plate and fixedly connected to the gearbox.

[0004] However, the aforementioned tapping machine still has the following drawbacks:

[0005] First, the lifting assembly achieves lifting and lowering only through a single lifting screw, and the nut of the lifting screw is directly fixed inside the gearbox. During the lifting and lowering process, the vibration inside the gearbox is transmitted to the nut, causing the connection between the lifting screw and the nut to loosen, thus causing the lifting and lowering to fail.

[0006] Secondly, during tapping, a series of drives such as the main motor, servo motor, and stroke cylinder are required to achieve the contact and separation between the tap and the end cap. The structure is relatively complex. At the same time, due to the slight difference in the hardness of the end cap during actual tapping, some end caps tap faster while others tap slower, which can easily cause the horizontal height of the tapping tap to be inconsistent, resulting in inconsistent tapping depth.

[0007] Third, if the end cap is placed directly on the positioning plate of the loading cylinder, it may fall onto the conveyor belt below if it is loose when the loading cylinder rotates, and then mix with the end caps being processed, which may cause errors in subsequent processing.

[0008] Therefore, it is necessary to improve upon the aforementioned shortcomings. Utility Model Content

[0009] The purpose of this invention is to provide a filter end cap tapping machine to solve the above-mentioned problems existing in the prior art.

[0010] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a filter end cap tapping machine, including a frame, on which a tapping mechanism for tapping and a rotating mechanism for fixing the end cap are provided. The tapping mechanism includes a tapping frame, a tapping device for tapping, a fixing frame for fixing the tapping device, and a lifting device for lifting and lowering located in the fixing frame. A gearbox is provided on the tapping frame. The lifting device includes a lifting motor, lifting screws located on both sides of the fixing frame, and a lifting bushing fixed to the upper end face of the gearbox. One end of the lifting screw is threaded into the lifting bushing, and the other end is provided with a synchronous gear. Support wheels are provided on both sides of the drive motor. The drive motor drives the lifting screws on both sides to lift and lower the tapping mechanism through a synchronous belt connected to the synchronous gear.

[0011] By adopting the above technical solution—positioning the lifting sleeve above the gearbox—during end cap tapping, the lifting motor rotates, driving the synchronous belt and synchronous gear to rotate. The support wheel at the drive motor transmission ensures a tight engagement between the synchronous belt and the drive motor, preventing loosening and allowing the lifting screw to move vertically relative to the lifting sleeve, thus raising and lowering the tapping device. This ensures the balance of the tapping mechanism during the raising and lowering process. Compared to existing technologies that use a combination of main motors, servo motors, and stroke cylinders to raise and lower the tapping cone, the structure adopted in this invention is simpler. Furthermore, the driving of the tapping device and the lifting device are separated, allowing the tapping device to tap in both forward and reverse directions. In addition, during tapping, gear vibration within the gearbox does not affect the stable connection between the lifting screw and the lifting sleeve, improving tapping quality and equipment operational stability, while also enhancing the ease of maintenance for the tapping machine.

[0012] The aforementioned filter end cap tapping machine can be further configured as follows: the tapping device includes several tapping sleeves, a main shaft passing through the tapping sleeves, a tapping rod threadedly connected to the main shaft, and a tapping motor for rotating the tapping sleeves. The tapping sleeves pass through a gearbox, and a gear section is provided on the outer periphery of the tapping sleeves. A tapping gear is fixedly connected to the gear section. The tapping motor and the tapping gear are linked through a gear set. Several lifting grooves are opened on the outer periphery of the tapping sleeves, and several limit bolts are provided on the main shaft in the lifting grooves. A clamping device is provided on the side of the main shaft near the rotating mechanism, and a tapping drill bit is detachably connected to the middle of the clamping device.

[0013] By adopting the above technical solution, multiple tapping sleeves enable multi-station tapping on the tapping machine. Simultaneously, the tapping sleeves, through lifting grooves and limit bolts on the spindle, achieve circumferential limiting and vertical lifting of the spindle. When the tapping drill bit contacts the end cap, it can continuously rotate and tap the spindle. Furthermore, the clamping device can quickly clamp and replace the tapping drill bit, improving the speed of disassembly and replacement of the tapping machine.

[0014] The above-mentioned filter end cap tapping machine can be further configured as follows: the tapping rod is located in the fixed frame and a fixed bushing is provided. The fixed bushing is provided with a tapping spring on its outer periphery. One end of the tapping spring is abutted and connected to the end face of the main shaft, and the other end is slidably connected to the outer periphery of the fixed bushing. The fixed bushing is provided with a retaining ring groove at the end away from the tapping rod. An elastic retaining ring is provided in the retaining ring groove. Several fixed bearings are provided between the tapping spring and the lower end face of the fixed bushing.

[0015] By adopting the above technical solution, the tapping rod, through the tapping spring, possesses excellent elastic buffering and stable support functions. During tapping, the tapping spring is compressed, providing a certain limiting force to the spindle. This allows the tapping rod to effectively absorb the impact force caused by uneven material hardness or machining errors in the filter end cap during the tapping process, preventing inconsistent tapping depths caused by inconsistent horizontal heights between the tapping rod and the spindle. It also effectively prevents damage due to excessive instantaneous force, extending the service life of the tapping rod. Simultaneously, the elastic retaining ring in the retaining ring groove of the fixed bushing effectively resists the tapping spring, stably confining the spring between the lower end face of the fixed bushing and the retaining ring. This ensures that the tapping spring will not shift or fall off during operation, guaranteeing the stable performance of the tapping rod's elastic buffering function. Furthermore, the multiple fixed bearings further enhance the rotational stability of the tapping rod, reduce friction and wear, improve tapping accuracy and equipment reliability, and make the tapping quality of the filter end cap more stable, meeting the requirements of high-quality production.

[0016] The above-mentioned filter end cap tapping machine can be further configured as follows: the clamping device includes a clamping and fixing block, a clamping groove is provided through the middle of the clamping and fixing block, clamping blocks are provided at both ends of the clamping groove, a limiting block is provided at one end of the clamping and fixing block near the tapping drill bit, a conical hole is provided in the middle of the limiting block, the tapping drill bit passes through a snap-fit ​​block, and a number of wedge-shaped blocks are provided on the outer periphery of the snap-fit ​​block, and the tapping drill bit is snapped into the conical hole through the wedge-shaped blocks on the snap-fit ​​block.

[0017] By adopting the above technical solution, the clamping device achieves reliable fixing and rapid replacement of the tapping drill bit. When the end of the tapping drill bit is located within the clamping block, the clamping blocks at both ends of the clamping groove in the middle of the clamping block are hinged to each other, enabling rapid clamping of the tapping drill bit. Furthermore, a tapered hole is provided in the middle of the limiting block near the tapping drill bit, which cooperates with the snap-fit ​​block and wedge block on the tapping drill bit, ensuring that the tapping drill bit is firmly fixed in the clamping device and will not loosen during tapping, thus guaranteeing the stability and accuracy of tapping. It also facilitates rapid replacement of the tapping drill bit. When it is necessary to replace the tapping drill bit with a different specification or one that is worn, simply pull the snap-fit ​​block out of the tapered hole, replace it with the new tapping drill bit, and then re-snap it, greatly improving replacement efficiency, reducing equipment downtime, and increasing production efficiency. In addition, the clamping block can accommodate tapping drill bits of different diameters, enhancing the versatility and flexibility of the clamping device, enabling the tapping machine to better meet the needs of various filter end cap thread processing.

[0018] The aforementioned filter end cap tapping machine can be further configured as follows: a sensor mounting plate is detachably connected to the outside of the lifting screw on the fixed frame. The sensor mounting plate has a sliding groove, and a sensor is installed in the sliding groove. A sensor element is installed on the end face of the lifting shaft sleeve connected to the lifting screw. The sensor determines the lifting height of the lifting mechanism by recognizing the sensor element. Several lifting slide rods are provided on the tapping frame. One end of the lifting slide rod is fixedly connected to the upper end face of the gearbox, and the other end is slidably connected to the fixed frame. The fixed frame achieves a sliding connection with the lifting slide rod through a lifting slider. An encoder is also provided at the connection between the lifting screw and the lifting shaft sleeve. The encoder includes a fixed bracket and a meter wheel. The outer circumference of the meter wheel is rotatably connected to the outer circumference of the tapping shaft sleeve.

[0019] By adopting the above technical solution—the detachable sensor mounting plate on the fixed frame and the sensor inside it cooperating with the sensing element on the end face of the lifting shaft sleeve—the lifting height of the lifting mechanism can be accurately identified. This allows the tapping machine to accurately control the tapping depth, avoiding substandard thread processing of the filter end cap due to lifting height errors, thus improving processing accuracy and product quality consistency. Simultaneously, the lifting slide bar on the tapping frame is slidably connected to the fixed frame via a lifting slider, enhancing the stability of the tapping frame during lifting and reducing the decrease in tapping accuracy caused by vibration or shaking, ensuring the smoothness of the tapping process. Furthermore, the encoder at the connection between the lifting screw and the lifting shaft sleeve, including a fixed bracket and a metering wheel, with the metering wheel rollingly connected to the outer circumference of the tapping shaft sleeve, can monitor the rotation of the tapping shaft in real time, providing accurate rotation data for the tapping process. This further improves the automation control level and processing accuracy of the tapping machine, making the thread processing of the filter end cap more efficient and accurate.

[0020] The above-mentioned filter end cap tapping machine can be further configured as follows: the rotating mechanism includes a rotating roller mounted on the frame, a number of polygonal mounting plates are provided on the outer periphery of the rotating roller, mounting and fixing plates are provided on the sides of the polygonal mounting plates, fixing seats corresponding to the tapping drill bit are provided on the mounting and fixing plates, fixing slots are provided on the fixing slots, end cap fixing blocks are provided on both sides of the fixing slots, sliding bolts are provided between each pair of end cap fixing blocks, and linkage rods are provided between the sliding bolts. The fixing seats move the sliding bolts toward the center through the linkage rods to fix the end caps.

[0021] By adopting the above technical solution, the rotating mechanism achieves efficient, stable fixing and precise positioning of the filter end cap. The polygonal mounting plate on the outer periphery of the rotating roller and the mounting fixing plates on its sides provide multiple fixing positions for the filter end cap, enabling the equipment to process multiple end caps simultaneously, thus improving production efficiency. The fixing seat on the mounting fixing plate has a fixing groove corresponding to the tapping drill bit, ensuring precise positioning of the filter end cap during the tapping process. This allows the tapping drill bit to accurately align with the threaded hole position of the end cap, avoiding thread processing defects caused by positional deviations. The end cap fixing blocks on both sides of the fixing groove, along with the sliding bolt and linkage rod structure between them, move the sliding bolt towards the center via the linkage rod to fix the end cap. This accommodates filter end caps of different sizes, enhancing the equipment's versatility and flexibility. Simultaneously, it facilitates quick loading and unloading of filter end caps by operators, reducing auxiliary operation time and further improving the equipment's production efficiency.

[0022] The aforementioned filter end cap tapping machine can be further configured as follows: a limiting device is provided at the edge of the mounting plate on the frame. The limiting device includes a limiting mounting plate fixedly mounted to the frame, limiting slide rods located at both ends of the limiting mounting plate, a limiting slider sleeved on the limiting slide rods, and abutting blocks detachably connected to the limiting sliders at both ends. A driving cylinder is provided between the limiting mounting plate and the abutting block. The bottom of the driving cylinder is hinged to the limiting mounting plate, and the other end is hinged to the abutting block. The limiting device moves the abutting block downwards until it abuts against the mounting plate through the driving cylinder to limit the rotation mechanism.

[0023] By adopting the above technical solution—the cooperation of the limiting slide rod and the limiting slider—the abutment block can move stably in the vertical direction. The drive cylinder, as the power source, is hinged at its bottom to the limiting mounting plate and at its other end to the abutment block, enabling precise control of the abutment block's movement. When the rotating mechanism needs to be limited, the drive cylinder pushes the abutment block downwards until it contacts the mounting plate, thus firmly fixing the rotating mechanism in the designated position. This not only ensures the stability of the rotating mechanism during tapping, avoiding machining errors and safety accidents caused by accidental rotation, but also provides a safe and stable operating environment for operators when replacing filter end caps or performing equipment maintenance. Furthermore, the detachable connection design of the limiting device makes it more convenient and faster to release the limit or maintain the limiting device, improving equipment maintenance efficiency and operational flexibility.

[0024] The above-mentioned filter end cap tapping machine can be further configured such that: the rotating roller is located inside the frame and is equipped with a brake disc, and a braking device is provided at the outer periphery of the brake disc, and the rotation mechanism controls the rotation angle of the rotating roller through the braking device.

[0025] By adopting the above technical solution, the rotary mechanism controls the rotation angle of the rotating roller through a braking device. This allows the filter end cap tapping machine to precisely control the rotation angle, improving processing accuracy. Simultaneously, it reduces mechanical impact, enhances equipment stability and reliability, extends service life, and lowers maintenance costs. Furthermore, it enables rapid positioning and processing, reducing the defect rate and thus improving production efficiency.

[0026] The above-mentioned filter end cap tapping machine can be further configured as follows: the frame is provided with a material receiving mechanism below the rotating mechanism, the material receiving mechanism includes material receiving inclined plates on both sides, a collection frame is provided below the material receiving inclined plates, collection rollers are provided on both sides of the collection frame, and a collection motor is provided at one side of the collection roller of the collection frame.

[0027] By adopting the above technical solution—a receiving ramp positioned below the rotating mechanism on the frame—the finished filter end caps can slide smoothly down the ramp, preventing accumulation or jamming during collection. A collection rack below the ramp further supports the sliding end caps, and collection rollers on both sides rotate under the drive of a collection motor, causing the filter end caps to move orderly to one side and arrange neatly, achieving automated collection and reducing the labor intensity and time cost of manual collection. This not only improves production efficiency but also ensures the integrity of the filter end caps during collection, avoiding damage that may be caused by manual handling and ensuring product quality. Furthermore, the entire receiving mechanism has a simple structure, stable operation, and is easy to maintain and clean, providing strong support for the continuous production of filter end caps.

[0028] The above-mentioned filter end cap tapping machine can be further configured as follows: a receiving inclined plate is provided upstream of the rotating roller and a baffle plate is provided, and a material storage bin is provided on the side of the frame of the rotating mechanism.

[0029] By adopting the above technical solution, the receiving inclined plate, located upstream of the rotating roller, effectively prevents the filter end caps to be processed from slipping onto the receiving inclined plate prematurely during the rotation of the rotating roller. This ensures that the end caps enter the fixed seat of the rotating mechanism for processing in the predetermined order, avoiding material confusion and processing sequence errors. Simultaneously, the material storage bin located on the side of the rotating mechanism provides ample storage space for the filter end caps. Operators can place a large number of end caps to be processed into the storage bin at once, reducing the frequency of loading and improving production efficiency. The design of the storage bin also allows the filter end caps to remain neatly arranged while awaiting processing, facilitating subsequent material retrieval and processing operations, further enhancing the automation level and production smoothness of the entire tapping machine.

Detailed Implementation

[0043] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0044] A filter end cap tapping machine includes a frame 1, on which a tapping mechanism 2 for tapping and a rotating mechanism 3 for fixing the end cap are provided. The tapping mechanism 2 includes a tapping frame 21, a tapping device 22 for tapping, a fixing frame 23 for fixing the tapping device 22, and a lifting device 24 for lifting and lowering located in the fixing frame 23. A gearbox 25 is provided on the tapping frame 21. The lifting device 24 includes a lifting motor 241, lifting screws 242 located on both sides of the fixing frame 23, and a lifting bushing 243 fixed to the upper end face of the gearbox 25. One end of the lifting screw 242 is threaded into the lifting bushing 243, and the other end is provided with a synchronous gear 244. Support wheels 246 are provided on both sides of the drive motor 241. The drive motor is connected to the synchronous gear 244 through a synchronous belt 245 to drive the lifting screws 242 on both sides to achieve the lifting and lowering of the tapping mechanism 2. The lifting sleeve is positioned above the gearbox 25. When tapping the end cap, the lifting motor 241 rotates, driving the synchronous belt 245 to drive the synchronous gear 244 to rotate. This causes the lifting screw 242 to move vertically relative to the lifting sleeve 243, thus raising and lowering the tapping device 22. This ensures the balance of the tapping mechanism 2 during the raising and lowering process. Compared with the existing technology that uses a combination of main motor, servo motor and stroke cylinder to raise and lower the tapping cone, the structure adopted in this utility model is simpler. At the same time, when the tapping device 22 is tapping, the gear vibration in the gearbox 25 will not affect the connection stability between the lifting screw 242 and the lifting sleeve 243, improving the tapping quality and the operational stability of the equipment, while also improving the convenience of tapping machine maintenance.

[0045] The tapping device 22 includes several tapping sleeves 221, a main spindle 222 passing through the tapping sleeves 221, a tapping rod 223 threadedly connected to the main spindle 222, and a tapping motor 224 for rotating the tapping sleeves 221. The tapping sleeves 221 pass through the gearbox 25. The tapping sleeves 221 are provided with a gear part 2211 on the outer periphery of the gearbox 25. The gear part 2211 is fixedly connected to the tapping gear 2212. The tapping motor 224 and the tapping gear 2212 are linked through a gear set 225. Several lifting grooves 2213 are opened on the outer periphery of the tapping sleeves 221. Several limit bolts 2221 are provided in the lifting grooves 2213 of the main spindle 222. A clamping device 226 is provided on the side of the main spindle 222 near the rotating mechanism 3. A tapping drill bit 227 is detachably connected to the middle of the clamping device 226. Multiple tapping sleeves 221 enable multi-station tapping on the tapping machine. Simultaneously, the tapping sleeves 221, through the lifting groove 2213 and the limiting bolt 2221 on the spindle 222, achieve circumferential limiting and vertical lifting of the spindle 222. When the tapping drill bit 227 contacts the end cap, it can continuously rotate and tap the spindle 222. Furthermore, the clamping device 226 can quickly clamp and replace the tapping drill bit 227, improving the speed of disassembly and replacement of the tapping machine.

[0046] The tapping rod 223 is located inside the fixed frame 23 and is provided with a fixed bushing 2231. A tapping spring 2232 is provided on the outer periphery of the fixed bushing 2231. One end of the tapping spring 2232 is connected to the end face of the spindle 222 and the other end is slidably connected to the outer periphery of the fixed bushing 2231. A retaining ring groove 2233 is provided at the end of the fixed bushing 2231 away from the tapping rod 223. An elastic retaining ring 2234 is provided in the retaining ring groove 2233. Several fixed bearings 2235 are provided between the elastic retaining ring 2234 and the lower end face of the fixed bushing 2231. The tapping rod 223, through the tapping spring 2232, possesses excellent elastic buffering and stable support functions. During tapping, the tapping spring 2232 is compressed, providing a certain limiting force to the spindle 222. This allows the tapping rod 223 to effectively absorb the impact force caused by uneven hardness of the filter end cap material or processing errors during the tapping process. This prevents different tapping depths of the end cap due to inconsistent horizontal heights between the tapping rod 223 and the spindle 222, and effectively prevents damage due to excessive instantaneous force, extending the service life of the tapping rod 223. Simultaneously, the elastic retaining ring 2234 within the retaining ring groove 2233 of the fixed bushing 2231 effectively resists the tapping spring 2232, stably confining the spring between the lower end face of the fixed bushing 2231 and the retaining ring. This ensures that the tapping spring 2232 will not shift or fall off during operation, guaranteeing the stable performance of the elastic buffering function of the tapping rod 223. In addition, the arrangement of multiple fixed bearings 2235 further enhances the rotational stability of the tapping rod 223, reduces friction and wear, improves tapping accuracy and equipment operation reliability, and makes the tapping quality of the filter end cap more stable, meeting the requirements of high-quality production.

[0047] The clamping device 226 includes a clamping and fixing block 2261. A clamping groove 2262 is provided through the middle of the clamping and fixing block 2261. Clamping blocks 2263 are provided at both ends of the clamping groove 2262. A limiting block 2264 is provided at one end of the clamping and fixing block 2261 near the tapping drill bit 227. A tapered hole 2265 is provided in the middle of the limiting block 2264. The tapping drill bit 227 is provided with a snap-fit ​​block 2266. A plurality of wedge-shaped blocks 2267 are provided on the outer periphery of the snap-fit ​​block 2266. The tapping drill bit 227 is snapped into the tapered hole 2265 through the wedge-shaped blocks 2267 on the snap-fit ​​block 2266. The clamping device 226 enables reliable fixing and quick replacement of the tapping drill bit 227. When the end of the tapping drill bit 227 is located in the clamping block 2263, the clamping blocks 2263 at both ends of the clamping groove 2262 in the middle of the clamping fixing block 2261 are hinged to each other, which enables quick clamping of the tapping drill bit 227. Furthermore, a tapered hole 2265 is provided in the middle of the limiting block 2264 near one end of the tapping drill bit 227. This hole cooperates with the locking block 2266 and wedge block 2267 on the tapping drill bit 227, ensuring that the tapping drill bit 227 is firmly fixed in the clamping device 226. This prevents loosening during tapping, guaranteeing the stability and accuracy of the tapping process. It also facilitates quick replacement of the tapping drill bit 227. When a different specification or worn tapping drill bit 227 needs to be replaced, simply pull the locking block 2266 out of the tapered hole 2265, replace it with a new tapping drill bit 227, and then re-lock it. This greatly improves replacement efficiency, reduces equipment downtime, and increases production efficiency. In addition, the clamping block 2263 can accommodate tapping drill bits 227 of different diameters, enhancing the versatility and flexibility of the clamping device 226, enabling the tapping machine to better meet the needs of various filter end cap thread processing.

[0048] A sensor mounting plate 2421 is detachably connected to the outside of the lifting screw 242 on the fixed frame 23. The sensor mounting plate 2421 has a sliding groove 2422, and a sensor is installed in the sliding groove 2422. A sensor element 2423 is provided on the end face of the lifting shaft sleeve 243 connected to the lifting screw 242. The sensor determines the lifting height of the lifting mechanism by recognizing the sensor element 2423. Several lifting slide rods 231 are provided on the tapping frame 21. One end of the lifting slide rod 231 is fixedly connected to the upper end face of the gearbox 25, and the other end is slidably connected to the fixed frame 23. The fixed frame 23 achieves a sliding connection with the lifting slide rod 231 through the lifting slider 232. An encoder 26 is also provided at the connection between the lifting screw 242 and the lifting shaft sleeve 243. The encoder 26 includes a fixed bracket 261 and a meter counting wheel 262. The outer periphery of the meter counting wheel 262 is rolledly connected to the outer periphery of the tapping shaft sleeve. The detachable sensor mounting plate 2421 on the fixed frame 23 and the sensor inside it cooperate with the sensor 2423 on the end face of the lifting bushing 243 to accurately identify the lifting height of the lifting mechanism. This allows the tapping machine to accurately control the tapping depth, avoiding unqualified filter end cap thread processing due to lifting height errors, and improving processing accuracy and product quality consistency. Simultaneously, the lifting slide bar 231 on the tapping frame 21 is slidably connected to the fixed frame 23 via the lifting slider 232, enhancing the stability of the tapping frame 21 during lifting and reducing the decrease in tapping accuracy caused by vibration or shaking, thus ensuring the smoothness of the tapping process. In addition, the encoder 26 at the connection between the lifting screw 242 and the lifting bushing 243 includes a fixed bracket 261 and a meter wheel 262. The meter wheel 262 is rolledly connected to the outer circumference of the tapping bushing, which can monitor the rotation of the tapping shaft in real time and provide accurate rotation data for the tapping process. This further improves the automation control level and processing accuracy of the tapping machine, making the thread processing of the filter end cover more efficient and accurate.

[0049] The rotating mechanism 3 includes a rotating roller 31 mounted on the frame 1. Several polygonal mounting plates 32 are arranged around the outer periphery of the rotating roller 31. Mounting plates 33 are located on the edges of the polygonal mounting plates 32. Mounting plates 33 have mounting seats 34 corresponding to the tapping drill bit 227. Mounting seats 34 have mounting grooves 341. End cap fixing blocks 342 are located on both sides of the mounting grooves 341. Sliding bolts 343 are arranged between each pair of end cap fixing blocks 342. Linkage rods 344 are provided between the sliding bolts 343. The mounting seats 34 move the sliding bolts 343 towards the center via the linkage rods 344 to fix the end caps. The rotating mechanism 3 achieves efficient, stable fixing and precise positioning of the filter end caps. The polygonal mounting plates 32 around the outer periphery of the rotating roller 31 and the mounting plates 33 on their edges provide multiple fixing positions for the filter end caps, enabling the equipment to process multiple end caps simultaneously and improving production efficiency. The mounting plate 33 has a mounting base 34 with a mounting groove 341 corresponding to the tapping drill bit 227. This ensures precise positioning of the filter end cap during the tapping process, allowing the tapping drill bit 227 to accurately align with the threaded hole of the end cap, avoiding thread defects caused by positional deviations. The end cap fixing blocks 342 on both sides of the mounting groove 341, along with the sliding bolt 343 and linkage rod 344, fix the end cap by moving the sliding bolt 343 towards the center via the linkage rod 344. This design accommodates filter end caps of different sizes, enhancing the equipment's versatility and flexibility. Simultaneously, it facilitates quick installation and removal of the filter end cap by operators, reducing auxiliary operation time and further improving equipment production efficiency.

[0050] A limiting device 35 is provided at the edge of the mounting plate of the frame 1. The limiting device 35 includes a limiting mounting plate 351 fixedly mounted to the frame 1, limiting slide rods 352 located at both ends of the limiting mounting plate 351, limiting sliders 353 sleeved on the limiting slide rods 352, and abutment blocks 354 detachably connected to the limiting sliders 353 at both ends. A driving cylinder 355 is provided between the limiting mounting plate 351 and the abutment blocks 354. The bottom of the driving cylinder 355 is hinged to the limiting mounting plate 351, and the other end is hinged to the abutment blocks 354. The limiting device 35 moves the abutment blocks 354 downwards until they abut against the mounting plate, thereby limiting the rotation mechanism 3. The cooperation between the limiting slide rods 352 and the limiting sliders 353 allows the abutment blocks 354 to move stably in the vertical direction. The drive cylinder 355 serves as the power source, with its bottom hinged to the limiting mounting plate 351 and its other end hinged to the abutment block 354, enabling precise control of the movement position of the abutment block 354. When the rotating mechanism 3 needs to be limited, the drive cylinder 355 pushes the abutment block 354 downward until it abuts against the mounting plate, thus firmly fixing the rotating mechanism 3 in the designated position. This not only ensures the stability of the rotating mechanism 3 during tapping, avoiding machining errors and safety accidents caused by accidental rotation of the rotating mechanism 3, but also provides a safe and stable operating environment for operators when replacing filter end caps or performing equipment maintenance. Furthermore, the detachable connection design of the limiting device 35 makes it more convenient and quick to release the limit or perform maintenance on the limiting device 35, improving the maintenance efficiency and operational flexibility of the equipment.

[0051] The rotating roller 31 is located within the frame and is equipped with a brake disc 311. A braking device 312 is located on the outer periphery of the brake disc 311. The rotating mechanism 3 stops the brake disc 311 through the braking device 312, thereby controlling the rotation angle of the rotating roller 31. The filter end cap tapping machine can precisely control the rotation angle of the rotating mechanism 3, improving processing accuracy. At the same time, it can reduce mechanical impact, enhance the stability and reliability of the equipment, extend its service life, and reduce maintenance costs. In addition, it can quickly position and process, reduce the defect rate, and thus improve production efficiency.

[0052] Below the rotating mechanism 3, the frame 1 is equipped with a receiving mechanism 4. The receiving mechanism 4 includes receiving inclined plates 41 on both sides, a collecting rack 42 below the receiving inclined plates 41, and collecting rollers 43 on both sides of the collecting rack 42. A collecting motor 44 is located on one side of the collecting roller 43 of the collecting rack 42. The receiving inclined plates 41 below the rotating mechanism 3 allow the finished filter end caps to slide smoothly down the inclined plates, preventing the end caps from accumulating or getting stuck during the receiving process. The collecting rack 42 below the receiving inclined plates 41 further supports the sliding end caps. Driven by the collecting motor 44, the collecting rollers 43 on both sides rotate, causing the filter end caps to move to one side in an orderly manner and arrange neatly, realizing automated collection and reducing the labor intensity and time cost of manual collection. This not only improves production efficiency but also ensures the integrity of the filter end caps during the collection process, avoiding damage that may be caused by human handling and ensuring product quality. Meanwhile, the entire receiving mechanism 4 has a simple structure, stable operation, and is easy to maintain and clean, providing strong support for the continuous production of filter end caps.

[0053] A receiving ramp 41 is located upstream of the rotating roller 31 and has a baffle 411. A storage bin 45 is located on the side of the rotating mechanism 3 on the frame 1. The baffle 411 on the receiving ramp 41 effectively prevents the filter end caps to be processed from slipping onto the receiving ramp 41 prematurely during the rotation of the rotating roller 31, ensuring that the end caps enter the fixed seat 34 of the rotating mechanism 3 sequentially according to the predetermined processing order, avoiding material confusion and processing sequence errors. Simultaneously, the storage bin 45 on the side of the rotating mechanism 3 on the frame 1 provides ample storage space for the filter end caps. Operators can place a large number of end caps to be processed into the storage bin 45 at once, reducing the frequency of loading and improving production efficiency. The design of the storage bin 45 also allows the filter end caps to remain neatly arranged while waiting for processing, facilitating subsequent material retrieval and processing operations, further enhancing the automation level and production smoothness of the entire tapping machine.
