Description

Technical Field

[0001] The utility model relates to the technical field of filter production, in particular to an automatic tapping device for a filter end cover. Background Art

[0002] The filter end cover has a circular cover body as its main body. A central screw hole is provided in the center of the cover body. There are several circular holes distributed around the central screw hole. The central screw hole needs to be tapped to form threads during the processing in order to realize automated tapping operation.

[0003] The prior art discloses corresponding automatic tapping equipment and automatic feeding equipment supporting the automatic tapping equipment, while the two conventional equipment are independent and need to be used in conjunction with each other. At the same time, since the filter end cover has a front and back side, and the general feeding equipment cannot identify the front and back sides of the end cover, it is necessary to distinguish the front and back sides of the end cover in advance when preparing the materials. For example, the Chinese patent CN217859165U previously applied by the applicant discloses a filter cover tapping automatic feeding machine, which needs to be used in conjunction with the automatic tapping equipment. When cooperating, there is a deviation because the model or product of the automatic tapping equipment is not unified. At the same time, although the feeding machine realizes automatic feeding, it needs to unify the front and back sides in advance when assembling the untapped filter end cover in advance. In the subsequent production process, it is found that when filling the filter end cover by manpower, the repeated action will inevitably lead to a decrease in attention, and then the filled filter end cover may have inconsistent front and back sides, which will cause problems in subsequent processes.

[0065] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0066] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0067] The utility model discloses an automatic tapping device for filter end covers, which is mainly used for automatic tapping of filter end covers, wherein the device integrates an automatic feeding mechanism for the filter end covers and an automatic tapping mechanism for the filter end covers, thus realizing a full process of feeding-transferring-tapping-discharging the filter end covers, 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.

[0068] like Figure 1 As shown, the filter end cover automatic tapping device includes a frame 2000 constructed of steel material and a shell 1000 covering the entire frame 2000, as shown in FIG. Figure 1 As shown, the coordinate axis X direction is used as the transmission direction of the filter end cover 3000, the Y direction is the transmission direction of the discharge mechanism, and the Z direction is the lifting direction.

[0069] like Figure 2As shown, the frame 2000 is provided with a first transfer station 10, a flipping station 20, a second transfer station 30, a tapping station 40 and a discharging station 50 in sequence along the transmission direction of the filter end cover 3000, wherein the first transfer station 10 is used for temporary storage of the filter end cover feeding, the flipping station 20 is used for identifying the front and back sides of the filter end cover and performing unified operations on the front and back sides, the second transfer station 30 is used for temporary storage of the flipped filter end cover, and the tapping station is used for tapping the filter end cover, and the discharging station is used for discharging the filter end cover after tapping, which are arranged in sequence along the X direction, so that the entire equipment is more reasonable and the overall structure is relatively compact.

[0070] like Figure 3 As shown, the frame 2000 has a work surface, and the frame is provided with a feeding mechanism 100, a clamping mechanism 500, a detection unit 400, a flipping mechanism 300, a lifting mechanism 200, a transfer mechanism 600, a tapping mechanism 700 and a discharging mechanism 4000. The feeding mechanism 100 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 from bottom to top along the Z direction, and are arranged in a straight line, so that the detection unit located above can detect the front and back sides of the filter end cover arranged on the lifting mechanism, and the clamping mechanism is arranged 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, the filter end cover is moved from the first transfer station to the flipping station and the filter end cover is moved from the flipping station to the second transfer station, and 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 600 can move along the X-axis. It is set between the second transfer station, i.e., the tapping station, and reciprocates to transfer the filter end cap from the second transfer station to the tapping station. In this embodiment, the transfer mechanism is set below the work surface, and the clamping mechanism is set above the work surface. The two are staggered to avoid interference in movement. At the same time, the transfer mechanism set below can also avoid the tapping mechanism, so that the tapping mechanism only needs to move in the Z direction and perform rotary tapping. The discharge mechanism 4000 is set at the discharge station to receive the filter end cap that has completed tapping and transport it out.

[0071] like Figure 8As shown, the feeding mechanism 100 is mainly used to move the filter end cover 3000 to the first transfer station 10. It is mainly used to cooperate with the feeding trolley. It includes a lifting plate 110. It is driven by a plurality of parallel linear guide rails and a screw rod 120. The lifting plate and the screw rod structure cooperate with each other to drive the lifting plate to move upward, thereby driving the filter end cover mounted on the feeding trolley 5000 to be lifted piece by piece. The linear guide rail is used for guidance. 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, which specifically discloses the specific structure of the filter cover (filter end cover) loading trolley and its cooperation structure with the automatic feeder. The feeding trolley used in this application is consistent with the Chinese patent previously applied for, so this application will not elaborate on it.

[0072] like Figure 6 As shown, the clamping mechanism 500 is disposed above the first transfer station 10 for clamping the filter end cover 3000 , and can move between the first transfer station 10 , the flipping station 20 and the second transfer station 30 .

[0073] The clamping mechanism 500 includes a first linear guide rail 510 , a first mounting seat 520 , a first lifting plate 530 and a first clamping assembly 540 .

[0074] The first linear guide rail 510 is arranged along the transmission direction of the filter end cover 3000. At the same time, there are two first linear guide rails 510, which are symmetrically arranged on both sides of the frame, and their linear directions are arranged in the X-axis direction, so that the first mounting seat matched with it can slide along the first linear guide rail 510 as a whole to ensure the consistency of direction;

[0075] The first mounting seat 520 forms a sliding fit with the first linear guide rail 510, and the length direction of the mounting seat is the Y direction, that is, it is arranged across the entire frame, and first sliders compatible with the first linear guide rails are arranged on both sides thereof. The first mounting seat is a plate-like structure, and its two ends are fixed to the first sliders through support frames, and the front and rear surfaces of the first mounting seat are mounting surfaces, and then by arranging a first lifting plate on the side facing the second transfer station, the first clamping assembly arranged thereon can move along the Z-axis direction.

[0076] The movement of the first mounting seat can be driven by a motor and a conveyor belt.

[0077] The first lifting plate 530 can be slidably set on the first mounting seat 520, and the sliding cooperation between the first lifting plate and the first mounting seat is realized through a plurality of linear guide rails. The first lifting plate is driven to move along the Z direction by a power source such as a cylinder or a motor, thereby causing the first clamping assembly to move downward or upward.

[0078] A plurality of first clamping assemblies 540 are disposed on the first lifting plate 530. The first clamping assemblies 540 can clamp the filter end cover when descending, thereby driving the filter end cover to move.

[0079] like Figure 7 As shown, the first clamping assembly 540 includes a first fixing seat 541, a first power source 542, a magnetic member and a plurality of limit rods 544. In this embodiment, the first clamping assembly uses a magnetic attraction method to adsorb the filter end cover.

[0080] The first fixed seat 541 is fixedly connected to the first lifting plate 530 for supporting the first clamping assembly, and is provided with a relatively movable push rod, the push rod portion is arranged inside the first fixed seat 541, and forms a limit fit with the first fixed seat 541 with a certain amount of sliding, and a spring is provided on the outer sleeve of the push rod. The design of the spring achieves a buffering effect, that is, when the first clamping assembly moves downward and touches the filter cover, it can be buffered by the spring so that it has a certain amount of deformation, thereby avoiding the hard top filter cover, resulting in excessive resistance of the first clamping assembly and causing damage.

[0081] The first power source 542 is connected to the first fixed seat 541. The first power source 542 adopts a cylinder, which has a movable rod. The movable rod has the state change of extension and retraction. The rear end of the first power source is fixedly connected to the push rod so that the movable amount of the push rod can be utilized.

[0082] The magnetic member 543 may be a magnet directly, and is fixedly connected to the movable rod of the first power source 542 .

[0083] A plurality of limit rods 544 are disposed at the front end of the first power source 542 and are circumferentially arranged around the magnetic member 543 , and the length of the limit rods 544 is greater than or equal to the maximum moving distance of the magnetic member 543 .

[0084] At the same time, a groove is provided at the position where the magnetic part cooperates with the limiting rod, and the limiting rod is arranged through the groove. In some embodiments, a through hole can also be directly provided on the magnetic part, and the limiting rod is arranged through the through hole, so that the limiting rod plays a guiding role.

[0085] At the same time, the limit rod first presses against the circumference of the filter end cover, and then drives the magnetic part to descend through the first power source 542, so that the magnetic force of the magnetic part adsorbs the filter end cover and clamps it. When the magnetic part is driven to rise, since the limit rod restricts the filter end cover, the movement of the magnetic part will not drive the filter end cover to move synchronously. Then, when the magnetic part leaves the filter end cover for a certain distance, since the magnetic force at this time is not enough to adsorb the filter end cover, the filter end cover will fall on the corresponding workstation, thereby completing the transfer of the filter end cover.

[0086] In other embodiments, the first clamping assembly may also use a finger cylinder, which utilizes the opposite movement of the claws to clamp the outer periphery of the filter end cover, thereby achieving a clamping effect. At the same time, a three-claw or two-claw method may also be used, which is inserted into the center of the filter end cover and opened outward for fixation. The fixing method can be diversified and can be selected according to needs.

[0087] like Figure 3 As shown, the detection unit 400 is located above the flipping station 20, and is used to detect the front and back states of the filter end cover 3000 located at the flipping station 20, and output a control signal. The detection unit can use a camera or a camera, which is fixed above the flipping station through a bracket. It recognizes the detected image through the central control machine. When it recognizes that the filter end cover with inconsistent front and back sides is identified, it outputs a control signal corresponding to the flipping mechanism to control it to flip 180°.

[0088] like Figure 4 and Figure 5 The flipping mechanism 300 is arranged at the flipping station 20, and clamps the filter end cover 3000 with non-uniform surfaces and flips it 180 degrees according to the received control signal.

[0089] The flipping mechanism 300 comprises:

[0090] Clamping jaws 310 are arranged facing each other, and a clamping position is formed between the two clamping jaws 310. The clamping position is circular or composed of two trapezoidal clamping jaws or two V-shaped clamping jaws, so as to clamp the filter end cover from the outer periphery of the filter end cover;

[0091] A driving assembly 320, used to drive the two claws 310 to move toward or in opposite directions. The driving assembly 320 may be a finger cylinder, which is commonly used to drive the claws to move;

[0092] The rotating assembly 330 adopts a rotating cylinder, which is fixedly arranged on the frame 2000 and is used to drive the driving assembly to rotate 180 degrees.

[0093] The specific working process is as follows: the two claws are driven by the driving assembly to move toward each other and clamp the filter end cover, and then according to the control signal, the rotating assembly at the supporting position of the filter end cover with non-uniform surfaces is controlled to rotate 180° to complete the unification of the front and back sides of the filter end cover.

[0094] The lifting mechanism 200 is disposed below the flipping mechanism 300 and is used to carry the filter end cover 3000 moved from the first transfer station 10 to the flipping station 20, and has a first position for rising to carry the filter end cover 3000 and a second position for falling to avoid the flipping mechanism 300.

[0095] The lifting mechanism 200 includes a support plate 210, both ends of which are provided with lifting components 220 for driving the support plate 210 to switch between a first position and a second position. The upper surface of the support plate 210 is provided with a plurality of support components 230 spaced apart along the length direction of the support plate 210.

[0096] The lifting assembly 220 adopts a cylinder, which uses the extension and retraction of a movable rod to achieve the lifting and lowering action of the support plate.

[0097] The support assembly is a support ring 230, which is arranged slightly higher than the support plate 210. 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.

[0098] The support ring can be replaced as required to adapt to the support of filter end covers of different sizes.

[0099] In order to better position the support ring 230, a positioning groove 240 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.

[0100] 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.

[0101] like Fig. 9 and Fig.10 As shown, a transfer table 7000 is provided between the second transfer station and the tapping station. The transfer table 7000 is a part of the work table, which is mainly used for the transfer support of the filter end cover on its surface. The transfer table is provided with a plurality of parallel grooves 7100, which 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 and drive the filter end cover on the transfer table to move, which has the function of guiding and avoiding. At the same time, the groove includes a narrow section at the second transfer station and a wide section at the tapping station. The narrow section supports the filter end cover, and the wide section allows the protrusion of the filter end cover to sink.

[0102] A gasket 7200 is provided at the second transfer station to play a buffering role and prevent the protruding part of the filter end from being embedded in the groove. At the same time, the clamping mechanism places it on the gasket, and the entire filter end cover is slightly higher than the transfer table to avoid always moving in contact with the transfer table when being driven by the transfer mechanism, causing wear to the filter end cover or the transfer table.

[0103] like Fig.11 As shown, the transfer mechanism 600 is arranged below the second transfer station 30 and is used to drive the filter end cover 3000 to be transferred from the second transfer station 30 to the tapping station 40.

[0104] like Fig.12 As shown, the transfer mechanism 600 includes a second linear guide rail 610, a second mounting seat 620, a second lifting plate and a second clamping assembly, which mainly drives the second mounting seat to slide relative to the second linear guide rail through a power source such as a motor, thereby driving the second lifting plate arranged on the second mounting seat to move synchronously, and the second lifting plate is lifted and lowered by a power source such as a cylinder, thereby forming a clamping fit between the second clamping assembly and the filter end cover. In the present application, the second clamping assembly is preferably a finger cylinder, and corresponding finger-shaped claws are arranged on its two driving ends, which are inserted into the central circular hole of the filter and opened to achieve clamping, thereby driving the filter end cover to move synchronously.

[0105] The second linear guide rail 610 is arranged along the transmission direction of the filter end cover 3000 and is arranged on both sides below the transfer table.

[0106] The second mounting seat 620 forms a sliding fit with the second linear guide rail 610, and its two ends are provided with sliders that slide with the second linear guide rail 610. The second mounting seat is a plate-like structure, and its two ends are fixed under the slider, and the top is used to install a power source such as a motor or a cylinder.

[0107] The second lifting plate 630 can be lifted and lowered above or below the second mounting seat 620. In the present embodiment, the second lifting plate is arranged below the second mounting seat. There are two of them, which are symmetrically arranged at both ends of the second mounting seat 620, and they cooperate with the guide sleeves on the second mounting seat through a plurality of guide rods. At the same time, the second lifting plate is driven to rise or fall accordingly by a power source arranged on the second mounting seat. At the same time, the projection area of ​​the second lifting plate is larger than the projection area of ​​the second mounting seat, which is the area projected by the two on the transfer table. Therefore, the second clamping assembly 640 can be arranged at the position of the second lifting plate not covered by the second mounting seat.

[0108] A plurality of second clamping assemblies 640 are arranged on the second lifting plate 630. The second clamping assemblies are a plurality of finger cylinders arranged at intervals on the second lifting plate and a finger-shaped clamping claw 650 driven by the finger cylinder. This structure is a conventional mechanism, such as Fig.12 As shown, no detailed description is given.

[0109] The specific working process is as follows: when the clamping mechanism moves the filter end cover to the second transfer station, the second clamping assembly rises under the drive of the second lifting plate, and the finger-shaped claw is inserted into the center hole of the filter end cover and clamped, and then the clamping mechanism drives it to move toward the tapping station. Due to the design that the initial position is slightly higher, when the filter end cover is driven to move, the filter end cover moves in mid-air. After moving a certain distance, that is, when approaching the tapping station, the second lifting plate descends, fits the filter end cover with the transfer table, and drives it to continue moving forward, and uses the latter to impact the filter end cover in the tapping station and send it to the discharge station. Preferably, a pressure plate 7300 is provided on the tapping station, which plays the role of pressing the filter end cover during tapping to prevent the pin needle 880 of the positioning mechanism below from lifting the filter end cover.

[0110] like Fig.11 As shown, in this embodiment, a positioning mechanism 800 is further provided below the tapping station. The positioning mechanism 800 has a first position perpendicular to the filter end cover transmission path and an inclined setting to allow the transfer mechanism 600 to move to a second position directly below the tapping station 40.

[0111] The positioning mechanism 800 can release the second position by rotation or by linear movement.

[0112] like Fig.13 As shown, the positioning mechanism 800 includes a fixed arm 850 and a rotating arm 840. 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 840 can be rotatably arranged with the fixed arm through the rotating shaft. A fixed plate 810 is provided at the other end of the rotating arm. The fixed plate connects the rotating arms on both sides. The fixed plate 810 is also provided with a cylinder 860 for driving the rotating arm to rotate relative to the rotating shaft. The fixed plate 810 is also provided with a movable plate 820 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 810 is provided with a driving cylinder for driving the movable plate to move relative to the guide rod or the guide sleeve.

[0113] The movable plate is provided with a plurality of spaced apart limit seats 830 along the length direction, and limit blocks are provided on both sides of the limit seats. A detachable positioning member 870 is provided in the limit seat 830, 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 is provided in the positioning hole.

[0114] The specific workflow is as follows:

[0115] When the transfer mechanism is feeding, the positioning mechanism is driven by the cylinder 860 to rotate away from the transfer mechanism, 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.

[0116] The tapping mechanism 700 is disposed at the tapping station 40 and performs a tapping operation on the filter end cover 3000 located at the tapping station 40 .

[0117] like Fig.14 As shown, the tapping mechanism 700 includes a third mounting seat 710, a third lifting plate 720, a second power source 740, a power assembly and a tapping unit 750. 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.

[0118] The third mounting base 710 is fixedly arranged on the frame for carrying the second power source 740 and the power assembly 730. 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.

[0119] The third lifting plate 720 is liftably arranged below the third mounting seat, and a transmission screw is 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 to move relative to each other.

[0120] The second power source 740 is used to drive the third lifting plate 720 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.

[0121] like Fig.14 As shown, the power assembly 730 is arranged on the third mounting seat 710, and a motor 731 can be used, which is fixedly arranged above the third mounting seat, and its shaft is connected to the reducer 732 through a coupling 733, and the reducer is linked to the tapping unit.

[0122] like Fig.15As shown, the tapping unit 750 is arranged below the third lifting plate 720 and is linked with the power assembly 730. The tapping unit 750 includes a transmission shaft 751 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 752 of the reducer. At the same time, the transmission shaft has a certain axial movement relative to the sleeve.

[0123] like Fig.16 As shown, a supply seat 753 is provided below the transmission shaft located at the third lifting plate 720, a supply spring 754 is provided between the supply seat and the third lifting plate, and the supply seat is fixedly connected to the transmission shaft.

[0124] 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.

[0125] The discharge mechanism 4000 is arranged at the discharge station 50 and is used to discharge the filter end cap 3000 after tapping. In this embodiment, the discharge mechanism is a discharge 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 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.

[0126] like Fig.17 and 18 As shown, an oil return tank 6000 is provided below the tapping station 40. The oil return tank 6000 is located below the transfer table and is used to recover the liquid used in tapping.

[0127] In this embodiment, the oil return tank is in the shape of a square groove, and an oil return hole is provided at the bottom thereof, which is connected to the oil circuit and then circulated by the oil pump. The bottom surface of the oil return tank 6000 is provided with a concave oil return groove 6100, such as Fig.19 As shown, the oil return groove 6100 is provided with an oil return port 6200 which is higher than the bottom surface of the oil return groove 6100. First, metal chips generated by tapping will be deposited in the oil return groove 6100 to ensure that there are no metal chips in the return oil. At the same time, a magnet 6300 with a through hole is provided in the oil return port 6200. Even if metal chips accumulate and enter the oil return hole, they will be absorbed by the magnet 6300 to ensure that the metal chips will not enter the oil return hole. The through hole of the magnet 6300 is compatible with the oil return hole 6400 to ensure the normal use of the oil return hole.

[0128] See also Fig.17A discharge slope 60 is provided between the discharge mechanism and the tapping station. The discharge slope 60 is provided with a plurality of oil holes and is located above the oil return tank, so that the residual liquid on the filter end cover can directly enter the oil return tank through the oil holes. An oil return plate 61 is also provided at the bottom of the discharge slope. One end of the oil return plate is located at the bottom of the oil hole, and the other end extends to the top of the oil return tank, ensuring that all liquid can return to the oil return tank, making the interior cleaner. At the same time, in order to accelerate the dripping of the residual liquid on the filter end cover, a position-adjustable blower mechanism 900 is provided at the discharge station 50. The blower 900 can be adjusted to align the air outlet with the discharge slope 60, and use wind force to blow away the liquid on the filter end cover.

[0129] like Fig. 20 As shown, the hair dryer mechanism 900 includes an air outlet assembly 910, both sides of which are fixedly connected to one end of a U-shaped bracket, and the other end of the U-shaped bracket 920 is connected and arranged on a frame. Meanwhile, a hydraulic rod 930 for angle adjustment is 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, and the air outlet assembly can also be rotated from top to bottom by rotation, so that the internal components can be inspected or replaced.
