[0057] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0058] It should be noted that all directional indications (such as up, down, left, right, front, back,...) in the embodiments of the present invention are only used to explain the relative positional relationship and movement conditions between various components in a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0059] The present invention discloses a transfer and positioning mechanism for a filter end cover, which is mainly used for transferring between the tapping and feeding stations in an automatic tapping device, and positioning the transferred filter end cover to prevent the filter end cover from rotating synchronously with the tapping mechanism when rotating.

[0060] The transfer and positioning mechanism includes a transfer platform 1000, which is fixed on a frame 4000. The front and rear ends of the transfer platform are set as a transfer station and a tapping station. The transfer station can be fed by a manipulator or other means. A transfer mechanism 100 and a positioning mechanism 200 are arranged at the bottom of the transfer platform. By the cooperation of the positioning mechanism and the transfer mechanism, when the transfer mechanism moves to the tapping station, the positioning mechanism can rotate to make room, and when the transfer mechanism returns, the positioning mechanism resets and positions the filter end cover.

[0061] The transfer platform 1000 has a transfer station at one end for a clamping mechanism 300 to place the filter end cover 2000, and a tapping station 40 at the other end for a tapping mechanism 40 to perform tapping operations on the filter end cover 2000.

[0062] As Figure 1 and Figure 2 shown, a transfer table surface 1000 is provided between the second transfer station and the tapping station. The transfer table surface 1000 is part of the workbench surface, and is mainly used for transferring and supporting the filter end cover on its surface. A number of parallel grooves 1100 are provided on the transfer table surface. The grooves 1100 connect the second transfer station and the tapping station, and are used for the fingers of the transfer mechanism to pass through the transfer table surface and drive the filter end cover located on the transfer table surface to move, playing a role of guiding and avoiding.

[0063] The width of the narrow section 1110 is smaller than the outer diameter of the protrusion of the filter end cover 2000, and the width of the wide section 1120 is larger than the outer diameter of the protrusion of the filter end cover 2000.

[0064] A gasket 1200 is provided at the second transfer station, which plays a buffering role. At the same time, it can prevent the protruding part of the end of the filter from being embedded in the groove, and enable the clamping mechanism to place it on the gasket. The entire filter end cap is slightly higher than the transfer table, avoiding being always in contact with the transfer table when driven by the transfer mechanism, which may cause wear to the filter end cap or the transfer table.

[0065] The transfer mechanism 100 is arranged under the transfer platform 1000 and can move between the transfer station and the tapping station 40. When the transfer mechanism 100 moves to the tapping station 40, it drives the filter end cap 2000 at the transfer station into the tapping station 40 and ejects the filter end cap 2000 originally located at the tapping station 40.

[0066] As Figure 3 shown, the transfer mechanism 100 is arranged under the second transfer station 30 and is used to drive the filter end cap 2000 from the second transfer station 30 to the tapping station 40.

[0067] As Figure 4 shown, the transfer mechanism 100 includes a linear guide rail 110, a mounting seat 120, a lifting plate 130 and a clamping assembly 140. It mainly drives the mounting seat to slide relative to the linear guide rail through a power source such as a motor, thereby driving the lifting plate arranged on the mounting seat to move synchronously. The lifting plate is lifted and lowered through a power source such as a cylinder, and then the clamping assembly and the filter end cap form a clamping fit. In this application, the clamping assembly is preferably a finger cylinder, and corresponding finger-shaped claws are arranged on its two driving ends, and clamping is achieved by inserting into the central circular hole of the filter and opening, and then the filter end cap can be driven to move synchronously.

[0068] The linear guide rail 110 is arranged along the transmission direction of the filter end cap 2000 and is arranged on both sides under the transfer table.

[0069] The mounting seat 120 forms a sliding fit with the linear guide rail 110, and sliders for sliding fit with the linear guide rail 110 are arranged at both ends of the mounting seat. The mounting seat is a plate-like structure, and its two ends are fixed under the sliders, and a power source such as a motor or a cylinder is installed above it.

[0070] The lifting plate 130 is arranged above or below the mounting seat 120 in a liftable manner. In this embodiment, the lifting plate is arranged below the mounting seat. There are two lifting plates, which are symmetrically arranged at both ends of the mounting seat 120, and they are matched with the guide sleeves on the mounting seat through a plurality of guide rods. At the same time, they are driven to rise or fall correspondingly by the power source arranged on the mounting seat. At the same time, the projected area of the lifting plate is larger than the projected area of the mounting seat. This projected area is the area of their projections on the transfer table, and then the clamping assembly 140 can be arranged at the position of the lifting plate not covered by the mounting seat.

[0071] A plurality of clamping assemblies 140 are arranged on the lifting plate 130. The clamping assemblies are a plurality of finger cylinders arranged at intervals on the lifting plate and finger-shaped claws driven by the finger cylinders. This structure is a conventional mechanism, such as Figure 4 shown, so it will not be described in detail.

[0072] Its specific working process is as follows. When the clamping mechanism moves the filter end cap to the second transfer station, the clamping assembly rises under the drive of the lifting plate. The finger-shaped claws are inserted into the central hole of the filter end cap and clamped. Then the clamping mechanism drives it to move towards the tapping station. Since the groove is slightly narrower at the initial position, the whole filter end cap is located above the transfer table, and there is a gap between the filter end cap and the transfer table by relying on the gasket. Therefore, when driving the filter end cap to move, the filter end cap moves suspended. After moving a certain distance, that is, when approaching the tapping station, it enters the wide part of the groove. The second lifting plate descends, fits the filter end cap with the transfer table, and drives it to continue to move forward, uses the latter to impact the filter end cap located in the tapping station, and sends it to the discharging station. Preferably, a pressing plate 1300 is provided at the tapping station to press the filter end cap during tapping to prevent the pin of the positioning mechanism below from lifting the filter end cap.

[0073] The positioning mechanism 200 is arranged on the lower side of the transfer platform 1000 and is located below the tapping station 40. The positioning mechanism 200 includes a first position with a transmission path perpendicular to the filter end cap 2000 and a second position that rotates to make way for the transfer mechanism 100 to move directly below the tapping station 40.

[0074] As Figure 3 shown, in this embodiment, a positioning mechanism 200 is further provided below the tapping station. The positioning mechanism 200 has a first position with a transmission path perpendicular to the filter end cap and a second position that is inclined to make way for the transfer mechanism 100 to move directly below the tapping station 40.

[0075] The positioning mechanism 200 can make way for the second position by rotation or by linear movement.

[0076] As Figure 5As shown, the positioning mechanism 200 includes a fixed arm 210 and a rotating arm 220. The fixed arm is fixed below or on both sides of the transfer table. A rotating shaft is provided at one end away from the transfer table. The rotating arm 220 can be rotatably arranged with the fixed arm through the rotating shaft. A fixed plate 230 is provided at the other end of the rotating arm. The fixed plate connects the rotating arms on both sides. The fixed plate 230 is also provided with a power source 260 for driving the rotating arm to rotate relative to the rotating shaft, such as a cylinder. The fixed plate 230 is also provided with a movable plate 240 arranged parallel to the fixed plate. The movable plate is connected to the fixed plate through a guide rod and a guide sleeve. At the same time, the fixed plate 230 is provided with a driving cylinder for driving the movable plate to move relative to the guide rod or the guide sleeve.

[0077] The movable plate is provided with a plurality of spaced limit seats 250 along the length direction, and limit blocks are provided on both sides of the limit seats. A detachable positioning member 270 is provided in the limit seat 250, and the positioning member slides in from both sides of the limit block and is fixed by bolts. A positioning hole is provided at the upper end of the positioning member, and a pin needle 280 is provided in the positioning hole.

[0078] The specific workflow is as follows:

[0079] When the transfer mechanism is feeding, the positioning mechanism rotates away from the transfer mechanism under the drive of the cylinder, thereby making room for the space below the tapping station. The transfer mechanism moves normally to the bottom of the tapping station and delivers the filter end cover to the tapping station, and then the transfer mechanism returns to the second transfer station. At the same time, the positioning mechanism returns to the center, and the positioning piece is placed directly below the tapping station, and then the cylinder is driven to drive the movable plate to move upward. At this time, the pin needle supports the filter end cover, and driven by the rotating force of the tapping mechanism, the filter end cover rotates synchronously, and when the holes around it are aligned with the pin needle, the pin needle is inserted into the corresponding hole under the action of the spring, and the filter end cover is hung, thereby limiting the rotation of the filter end cover, so that the tapping mechanism can perform tapping operations on the filter end cover.

[0080] The present invention also discloses an automatic tapping device for a filter end cover, which is mainly used for the automatic tapping of the filter end cover, wherein the device integrates an automatic feeding mechanism for the filter end cover and an automatic tapping mechanism for the filter end cover, thus realizing the whole process of feeding-transferring-tapping-discharging the filter end cover, eliminating the tediousness of the previous need for multiple devices to cooperate, and the multi-purpose use of one machine can reduce the demand for the operating area.

[0081] like Figure 6 As shown, the filter end cover automatic tapping device includes a frame 4000 constructed of steel material and a shell 3000 covering the entire frame 4000, as shown in FIG. Figure 6 As shown, the coordinate axis X direction is used as the transmission direction of the filter end cover 2000, the Y direction is the transmission direction of the discharge mechanism, and the Z direction is the lifting direction.

[0082] As shown Figure 7 in the figure, along the transmission direction of the filter end cap 2000 on the frame 4000, a first transfer station 10, a flipping station 20, a second transfer station 30, a tapping station 40 and a discharging station 50 are successively arranged. Among them, the first transfer station 10 is used as a temporary storage station for feeding the filter end cap, the flipping station 20 is used for identifying the front and back sides of the filter end cap and performing unified operations on the front and back sides, the second transfer station 30 is used for temporarily storing the flipped filter end cap, the tapping station is used for tapping the filter end cap, and the discharging station is used for discharging the filter end cap after tapping. They are successively arranged along the X direction, making the whole device more reasonable and the overall structure more compact.

[0083] As shown Figure 8 in the figure, the frame 4000 has a workbench surface, and the transfer surface is also a part of the workbench surface. An inlet feeding mechanism 500, a clamping mechanism 300, a detection unit 700, a flipping mechanism 600, a lifting mechanism 800, a transfer mechanism 100, a tapping mechanism 400 and a discharging mechanism 5000 are arranged on the frame. Among them, the inlet feeding mechanism 500 is arranged at the first transfer station, and the lifting mechanism, the flipping mechanism and the detection unit are arranged at the flipping station. At the same time, the three are arranged in a straight line from bottom to top along the Z direction, which is convenient for the detection unit above to detect the front and back sides of the filter end cap arranged on the lifting mechanism. The clamping mechanism is set to move along the X axis, and it can move between the first transfer station, the flipping station and the second transfer station, that is, it can move the filter end cap from the first transfer station to the flipping station and move the filter end cap from the flipping station to the second transfer station. At the same time, it can also move from the flipping station to the first transfer station or the second transfer station or move in the opposite direction. The transfer mechanism 100 can move along the X axis, and it is arranged to reciprocate between the second transfer station, that is, the tapping station, for transferring the filter end cap from the second transfer station to the tapping station. In this embodiment, the transfer mechanism is arranged below the workbench surface, and the clamping mechanism is arranged above the workbench surface. The two are arranged staggeredly to avoid action interference. At the same time, the transfer mechanism arranged below can also avoid the tapping mechanism, so that the tapping mechanism only needs to move in the Z direction and rotate for tapping. The discharging mechanism 5000 is arranged at the discharging station for receiving the filter end cap after tapping and conveying it out.

[0084] As shown Figure 13As shown, the feeding mechanism 500 is mainly used to move the filter end cap 2000 to the first transfer station 10. It is mainly used to cooperate with the feeding trolley. It includes a lifting plate 510, which is driven by a plurality of parallel linear guides and lead screws 520. By means of the screw drive cooperation between the lifting plate and the lead screw, the lifting plate is driven to move upward, and then the filter end caps sleeved on the feeding trolley 6000 are lifted one by one. The linear guide is used for guiding. The specific structure of the feeding trolley and its cooperation with the equipment can refer to the Chinese patent CN218431348U previously applied by the applicant. It specifically discloses the specific structure of the filter cover (filter end cap) loading trolley and its cooperation structure with the automatic feeding machine. The feeding trolley adopted in this application is the same as the Chinese patent of the previous application, so this application will not expand on it.

[0085] As Figure 8 and Figure 11 shown, the clamping mechanism 300 is arranged above the first transfer station 10, used to clamp the filter end cap 2000, and can move between the first transfer station 10, the flipping station 20 and the second transfer station 30.

[0086] The clamping mechanism 300 includes a linear guide, a first mounting seat 320, a first lifting plate 330 and a first clamping mechanism 310.

[0087] The linear guide is arranged along the transmission direction of the filter end cap 2000. At the same time, there are two linear guides, symmetrically arranged on both sides of the frame, and its linear direction is set in the X-axis direction. Thus, the first mounting seat cooperating with it can slide integrally along the linear guide to ensure the consistency of direction;

[0088] The first mounting seat 320 forms a sliding fit with the linear guide. The length direction of the mounting seat is the Y direction, that is, it spans the entire frame. Sliders adapted to the linear guide are provided on both sides of it. The first mounting seat is a plate-like structure, and its two ends are fixed on the sliders through support frames. Moreover, the front and back surfaces of the first mounting seat are mounting surfaces. Thus, by arranging the first lifting plate on the side facing the second transfer station, the first clamping mechanism arranged on it can move in the Z-axis direction.

[0089] The movement of the first mounting seat can rely on the way of a motor and a conveyor belt to drive its action.

[0090] The first lifting plate 330 is slidably arranged on the first mounting seat 320. The sliding fit between the first lifting plate and the first mounting seat is realized through a number of linear guides. Using a power source, such as a cylinder or a motor, drives the first lifting plate to move in the Z direction, and then the first clamping mechanism moves downward or upward.

[0091] A number of first clamping mechanisms 310 are arranged on the first lifting plate 330. The first clamping mechanism 310 can clamp the filter end cover when descending, so as to drive its movement.

[0092] As Figure 12 shown, the first clamping mechanism 310 includes a first fixed seat 311, a first power source 312, a magnetic member and a number of limiting rods 314. In this embodiment, the first clamping mechanism uses a magnetic adsorption cooperation method to adsorb the filter end cover.

[0093] Among them, the first fixed seat 311 is fixedly connected to the first lifting plate 330, used to support the first clamping mechanism. At the same time, it is provided with a relatively movable ejector rod. Part of the ejector rod is located inside the first fixed seat 311 and forms a limiting fit with it with a certain sliding amount. At the same time, a spring is sleeved outside the ejector rod. The design of the spring realizes the buffering function, that is, when the first clamping mechanism moves downward and touches the filter cover plate, it can have a certain deformation amount through the buffering of the spring, thereby avoiding directly hitting the filter cover plate, resulting in too much resistance of the first clamping mechanism and causing damage.

[0094] The first power source 312 is connected to the first fixed seat 311. The first power source 312 uses a cylinder, which has a movable rod, and the state of the movable rod changes between extending and retracting. The rear end of the first power source is fixedly connected to the ejector rod, and thus the movement amount of the ejector rod can be utilized.

[0095] The magnetic member 313 can directly use a magnet and is fixedly connected to the movable rod of the first power source 312.

[0096] A number of limiting rods 314 are arranged at the front end of the first power source 312 and are circumferentially arranged around the magnetic member 313, and their length is greater than or equal to the maximum moving distance of the magnetic member 313.

[0097] At the same time, a groove is provided at the position where the magnetic member cooperates with the limiting rod. The limiting rod passes through the groove. In some embodiments, through holes can also be directly provided on the magnetic member, and the limiting rod passes through the through holes, so that the limiting rod plays a guiding role.

[0098] At the same time, the limiting rod first abuts against the circumference of the filter end cover, and then the first power source 312 drives the magnetic member to descend, so that the magnetic force of the magnetic member adsorbs the filter end cover and clamps it. When the magnetic member is driven to rise, since the limiting rod restricts the filter end cover, the movement of the magnetic member will not drive the filter end cover to move synchronously. Therefore, when the magnetic member leaves the filter end cover by a certain distance, since the magnetic force at this time is not sufficient to adsorb the filter end cover, the filter end cover will fall on the corresponding working position, thus completing the transfer of the filter end cover.

[0099] In other embodiments, the first clamping mechanism can also adopt a finger cylinder, using the opposite movement of the jaws to clamp the outer periphery of the filter end cap, thereby playing a clamping role. At the same time, it can also adopt a three-jaw or two-jaw method, insert into the center of the filter end cap, and expand outward for fixation. Its fixation method can be diversified and can be selected according to requirements.

[0100] As Figure 8 shown, the detection unit 700 is located above the flipping station 20 and is used to detect the front and back states of the filter end cap 2000 located at the flipping station 20 and output a control signal. The detection unit can adopt a camera or a webcam, which is fixed above the flipping station through a bracket. It identifies the detected image through a central control computer. When it identifies a filter end cap with inconsistent front and back sides, it outputs a control signal to the corresponding flipping mechanism to control it to flip 180°.

[0101] As Figure 9 and Figure 10 described, the flipping mechanism 600 is arranged at the flipping station 20 and, according to the received control signal, clamps and flips the filter end cap 2000 with non-uniform surfaces by 180 degrees.

[0102] The flipping mechanism 600 includes:

[0103] Jaws 610 arranged oppositely, and a clamping position is formed between the two jaws 610. The clamping position is circular or composed of two trapezoidal clamping openings or composed of two V-shaped clamping openings, so as to clamp the filter end cap from the outer periphery of the filter end cap;

[0104] A driving component 620 for driving the two jaws 610 to move towards or away from each other. The driving component 620 can adopt a finger cylinder, which is commonly used to drive the jaws to move;

[0105] A rotating component 630, which adopts a rotary cylinder and is fixedly arranged on the frame, and is used to drive the driving component to rotate 180°.

[0106] Its specific working process is as follows: The two jaws are driven by the driving component to move towards each other and clamp the filter end cap. Then, according to the control signal, the rotating component of the clamping position of the filter end cap with non-uniform surfaces is controlled to rotate 180°, completing the unification of the front and back sides of the filter end cap.

[0107] The lifting mechanism 800 is arranged below the flipping mechanism 600 and is used to carry the filter end cap 2000 transferred from the first transfer station 10 to the flipping station 20, and it has a first position for lifting and carrying the filter end cap 2000 and a second position for descending to avoid the flipping mechanism 600.

[0108] The lifting mechanism 800 includes a support plate 810, both ends of which are provided with lifting components 820 for driving the support plate 810 to switch between a first position and a second position, and the upper surface of the support plate 810 is provided with a plurality of support components 830 spaced apart along the length direction of the support plate 810.

[0109] The lifting assembly 820 adopts a cylinder, which uses the extension and retraction of a movable rod to achieve the lifting and lowering action of the support plate.

[0110] The support assembly is a support ring, which is arranged slightly higher than the support plate 810. When the filter end cover is placed on the support ring, the outer periphery of the filter end cover is in a suspended state, which is convenient for clamping by the claws. The diameter of the support ring is adapted to the diameter of the middle protruding position of the filter end cover.

[0111] The support ring can be replaced as required to adapt to the support of filter end covers of different sizes.

[0112] In order to better position the support ring, a positioning groove 840 is provided on the support plate, and the support ring is embedded in the positioning groove to ensure that its position will not be offset.

[0113] The specific working process is as follows: the claws are in an open state, the filter end cover is clamped by the clamping assembly and moved to the flipping station, the support plate moves upward, the filter end cover is placed on the support plate, the clamping assembly avoids, and then the detection unit detects the front and back sides of the filter end cover, and then the flipping mechanism clamps the filter end cover, the support plate moves downward to avoid the flipping mechanism, and then the corresponding flipping mechanism flips, the support plate moves upward, the flipping mechanism releases the filter end cover, and then the clamping mechanism moves to the flipping station, and then the clamping mechanism transfers the filter end cover. In other embodiments, the filter end cover can also be clamped by the flipping mechanism, and then the front and back sides can be detected by the detection unit.

[0114] The tapping mechanism 700 is disposed at the tapping station 40 and performs a tapping operation on the filter end cover 2000 located at the tapping station 40 .

[0115] like Figure 14 As shown, the tapping mechanism 400 includes a third mounting seat 410, a third lifting plate 420, a second power source 440, a power assembly 430 and a tapping unit 450. The second power source is used to drive the third lifting plate to rise and fall relatively, so that the tapping unit approaches the filter end cover, and the power assembly is used to drive each tapping unit to rotate, thereby realizing the tapping operation on the filter end cover.

[0116] The third mounting base 410 is fixedly arranged on the frame for carrying the second power source 440 and the power assembly 430. It is directly fixedly connected to the frame, making the connection between the two more reliable and capable of bearing a greater weight to ensure the stability of the power assembly.

[0117] The third lifting plate 420 is liftable and arranged below the third mounting seat, and transmission screw rods are arranged between the two ends of the third lifting plate and the third mounting seat, and the entire third lifting plate is driven by the screw rods for relative movement.

[0118] The second power source 440 is used to drive the third lifting plate 420 to move up and down. It includes a motor and a pulley transmission mechanism connected to the motor. The motor drives the pulley linked to the screw rod to move, thereby driving the third lifting plate to move up and down relative to the screw rod.

[0119] like Figure 14 As shown, the power assembly 430 is arranged on the third mounting seat 410, and a motor 431 can be used, which is fixedly arranged above the third mounting seat, and its shaft is connected to the reducer 432 through a coupling 433, and the reducer is linked to the tapping unit.

[0120] like Figure 15 As shown, the tapping unit 450 is arranged below the third lifting plate 420 and is linked with the power assembly 430. The tapping unit 450 includes a transmission shaft 451 that can be driven to rotate by a motor. A spline is provided on the transmission shaft, and the transmission shaft forms a spline transmission cooperation with the sleeve 452 of the reducer. At the same time, the transmission shaft has a certain axial movement relative to the sleeve.

[0121] like Figure 16 As shown, a supply seat 453 is provided below the transmission shaft located at the third lifting plate 420, a supply spring 454 is provided between the supply seat and the third lifting plate, and the supply seat is fixedly connected to the transmission shaft.

[0122] When the third lifting plate descends, the tapping unit contacts the filter end cover and continues to be forced downward. Since the tapping unit is blocked, the supply spring between the supply seat and the third lifting plate is compressed. Then, when the tapping unit taps the filter end cover, the supply spring is gradually reset, so that the tapping unit continues to move along the axial direction of the center hole of the filter end cover, thereby completing the tapping operation of the entire center hole.

[0123] The discharging mechanism 5000 is arranged at the discharging station 50 and is used to discharge the filter end cap 2000 after tapping. In this embodiment, the discharging mechanism is a discharging track, and its conveying direction is the Y direction. The filter end cap that slides on its track is directly delivered through the conveyor belt. In other embodiments, a corresponding platform or a collection frame or the like can also be provided, that is, it does not need to automatically move to the next process, and can be directly collected.

[0124] As Figure 17 and 18 shown, a return oil tank 7000 is provided below the tapping station 40. The return oil tank 7000 is located below the transfer table and is used to recover the liquid used during tapping.

[0125] In this embodiment, the return oil tank is in the shape of a square groove, and its bottom is provided with an oil return hole, which is connected to the oil circuit and then circulated by an oil pump. The bottom surface of the return oil tank 7000 is provided with a recessed oil return groove 7100, as Figure 19 shown, and an oil return port 7200 higher than the bottom surface of the oil return groove 7100 is provided in the oil return groove 7100. First, the metal chips generated by tapping will be deposited in the oil return groove 7100 to ensure that there are no metal chips in the oil return. At the same time, a magnet 7300 with a through hole is provided in the oil return port 7200. Even if the metal chips accumulate and enter the oil return hole, they will be adsorbed by the magnet 7300 to ensure that the metal chips do not enter the oil return hole. The through hole of the magnet 7300 is adapted to the oil return hole 7400 to ensure the normal use of the oil return hole.

[0126] See Figure 17 , an unloading slope 60 is provided between the unloading mechanism and the tapping station. A number of oil holes are provided on the unloading slope 60 and are located above the return oil tank, so that the liquid remaining on the filter end cover can directly enter the return oil tank through the oil holes. A return oil plate 61 is also provided at the bottom of the unloading slope. One end of the return oil plate is located at the lowest position of the oil hole, and the other end extends above the return oil tank to ensure that all the liquid can return to the return oil tank, making the inside cleaner. At the same time, in order to accelerate the dripping of the liquid remaining on the filter end cover faster, a blowing mechanism 900 with adjustable position is provided at the unloading station 50. The blower 900 can be adjusted so that the air outlet is aligned with the unloading slope 60, and the liquid on the filter end cover is blown off by the wind force.

[0127] As Figure 20 shown, the blowing mechanism 900 includes an air outlet assembly 910. Both sides of the air outlet assembly are fixedly connected to one end of a U-shaped bracket. The other end of the U-shaped bracket 920 is hinged to the frame. At the same time, a hydraulic rod 930 for angle adjustment is also provided on the lower side of the U-shaped bracket. By manually adjusting the position of the air outlet assembly, the angle of the air outlet assembly can be changed. At the same time, the air outlet assembly can also be rotated from above to below by rotation, so as to repair or replace the internal components.

[0128] The embodiments should not be regarded as limitations on the present invention, but any improvements based on the spirit of the present invention should be within the protection scope of the present invention.
