As shown in FIG. 1, the invention discloses an environment-friendly air blowing type dust removing device 10, which comprises a conveying device 20 and a dust removing device 30. The processed plastic parts are placed on the conveyor 20, are conveyed into the dust removing device 30 along with the operation of the conveyor 20, and are taken out of the dust removing device 30 by the conveyor 20 after dust removing treatment.

As shown in fig. 1 and 2, the dust removing device 30 includes: a protective cabinet 100, a blowing mechanism 200 and a dust suction mechanism 300. The protection cabinet 100 is a hollow structure, a feeding hole 110 (shown in fig. 1) and a discharging hole (not shown) are formed in the protection cabinet 100, the conveying device 20 penetrates through the feeding hole 110 and the discharging hole (not shown), and the blowing mechanism 200 and the dust suction mechanism 300 are installed in the protection cabinet 100.

As shown in fig. 1 and 2, the transfer device 20 includes: the conveying device comprises a conveying rack 400, a conveying belt 500 and a tension driving wheel 600, wherein the conveying belt 500 is wound on the conveying rack 400, the conveying belt 500 is partially positioned in the protection cabinet 100, and the tension driving wheel 600 drives the conveying belt 500 to rotate.

Specifically, as shown in fig. 2, a dust insulation isolation plate 130 is disposed inside the protection cabinet 100, and the dust insulation isolation plate 130 divides the interior of the protection cabinet 100 into a dust removal area 101 and a dust insulation area 102. The conveyor 500 includes a conveying surface 501 and a recovery surface 502, the conveying surface 501 is located in the dust-removing area 101, and the recovery surface 502 is located in the dust-insulating area 102. The conveyance surface 501 and the recovery surface 502 merely indicate relative positions of the conveyor 500, and the conveyance surface 501 is changed to the recovery surface 502 and the recovery surface 502 is changed to the conveyance surface 501 as the conveyor 500 rotates, that is, the conveyance surface 501 and the recovery surface 502 alternate with the rotation of the conveyor 500.

In the present embodiment, as shown in fig. 2, the blowing mechanism 200 includes a blowing nozzle 210 and a gas transmission duct 220 communicating with the blowing nozzle 210, and the gas transmission duct 220 is connected to an external air pressure machine. The dust suction mechanism 300 includes a dust collector 310 and a dust collection port 320, and the dust collector 310 and the dust collection port 320 are connected by a dust suction pipe 330. The blowing nozzle 210 and the dust collecting port 320 are located in the dust removing area 101, and the dust collector 310 is located in the dust insulating area 102.

Note that the dust-proof isolation sheet 130 functions to isolate dust. During the dust removing process, the dust removing area 101 is filled with dust, and the dust collector 310 and the important electronic control components of the dust removing device 10 need to avoid dust interference, for this reason, a dust-proof isolation board 130 is designed inside the protection cabinet 100. The dust insulation isolation plate 130 divides the interior of the protection cabinet 100 into the dust removal area 101 and the dust insulation area 102, and dust in the dust removal area 101 cannot pass through the dust insulation isolation plate 130 to enter the dust insulation area 102, so that important electronic control elements are protected from being interfered by the dust, and the running reliability of the dust removal equipment is improved.

In this embodiment, as shown in fig. 1, the conveyor 500 is provided with a vent 510, and the conveying surface 501 is located between the blowing nozzle 210 and the dust collecting port 320.

The working principle of the environment-friendly air blowing type dust removing device 10 of the present invention is described below with reference to the above structure:

in operation, as shown in fig. 1 and 2, the tension driving wheel 600 drives the conveyor belt 500 to rotate, so that the plastic parts placed on the conveying surface 501 enter the dust removing area 101 inside the protection cabinet 100 from the feeding port 110. At this time, as shown in fig. 2, the air blowing nozzle 210 located above the conveying surface 501 blows out high-pressure air to blow up the dust adhering to the surface of the plastic part, so that the dust is detached from the plastic part. At the same time, the dust collector 310 is in operation and there is suction at the dust collection port 320. The dust scattered after being blown up by the dust collector 310 passes through the ventilation holes 510 of the conveyor belt 500 and is sucked into the dust collection port 320. The dust removing treatment of the plastic parts is completed, and the plastic parts after the dust removing treatment leave the dust removing area 101 from the discharge port along with the movement of the conveyor belt 500.

In the embodiment, as shown in fig. 1, preferably, partition curtains 140 are disposed at the inlet 110 and the outlet of the protection cabinet 100. The partition curtain 140 can prevent scattered dust from scattering outside the dust removal area 101 to pollute the workshop environment; without blocking the plastic parts from entering or leaving the dusting area 101.

Since the important electronic control components of the dust removing device 10 are all disposed in the dust-proof area 102 of the protection cabinet 100, and the gas ejected from the blowing nozzle 210 in the dust removing area 101 is high-pressure gas, necessary locking protection needs to be performed on the protection cabinet 100 for property safety protection of the device and personal safety protection of workers. However, if the securable container 100 is keyed, the operator is required to find a matching key to unlock each time; if the protective cabinet 100 is equipped with an electronic combination lock, the cost of the equipment will be greatly increased. Therefore, the designer makes a special design for the protection cabinet 100 of the environment-friendly air blowing type dust removing equipment 10 of the invention, which is as follows:

as shown in fig. 1 and 3, the protection cabinet 100 includes: the cabinet comprises a cabinet body 150, a cabinet door 160 and a safety lock 700, wherein the cabinet door 160 covers the cabinet body 150, and the safety lock 700 is arranged on the cabinet door 160.

As shown in fig. 4, security lock 700 comprises: a lock body base 710, a rotating assembly 720, and a sliding assembly 730. The lock base 710 is mounted on the cabinet door 160, and the lock base 710 is fixedly provided with a one-way ratchet 711 (as shown in fig. 5).

Specifically, as shown in fig. 5, the rotating assembly 720 includes: a driving rotary shaft 721, a driven rotary plate 722 and a one-way pawl 723 matched with the one-way ratchet 711. The driven turntable 722 is rotatably disposed on the lock body base 710, the driving rotating shaft 721 penetrates through the lock body base 710 and the cabinet door 160, the driving rotating shaft 721 is used for driving the driven turntable 722, one end of the unidirectional pawl 723 is rotatably disposed on the driven turntable 722 through a torsion spring (not shown), and the other end of the unidirectional pawl 723 is pressed on the wheel surface of the unidirectional ratchet 711. The one-way pawl 723 cooperates with the one-way ratchet 711 to rotate the driven turntable 722 in only one direction, the operation of which will be described below.

Specifically, as shown in fig. 5, the sliding assembly 730 includes a sliding rod 731 and a return spring 732, the sliding rod 731 is slidably mounted on the lock body base 710, the sliding rod 731 includes a connecting end 734 and a locking end 735, the connecting end 734 of the sliding rod 731 is connected to the driven turntable 722 through a connecting rod 736, the sliding rod 731 is provided with a positioning shoulder 737, and one end of the return spring 732 is connected to the positioning shoulder 737, and the other end is connected to the lock body base 710. The cabinet body 150 is provided with a locking groove 151 (shown in fig. 3) engaged with the locking end 735.

In this embodiment, as shown in fig. 5, the driven turntable 722 is provided with a driven turning post 724, and the driving shaft 721 is provided with a driving turning end 721a matching with the driven turning post 724. One end of the connecting rod 736 is hinged to the driven toggle post 724, and the other end of the connecting rod 736 is hinged to the connecting end 734 of the sliding rod 731, as shown in fig. 6.

In this embodiment, as shown in fig. 3 and fig. 5, a manual knob 725 is disposed on the active rotating shaft 721, and the manual knob 725 is located outside the cabinet door 160.

The specific operation principle of the security lock 700 will be explained in conjunction with the present embodiment, and for better explanation, as shown in fig. 6, the change process of the security lock 700 is divided into three main states, which are denoted by reference numerals 1 to 3:

the safety lock 700 is in an initial state as shown in fig. 4 and number 1 of fig. 6, the driven dial 724 of the driven dial 722 is at an upper left position relative to the central axis of the driving rotary shaft 721, the return spring 732 is in a compressed state, the sliding rod 731 has a downward sliding tendency under the elastic potential energy of the return spring 732, and accordingly, the driven dial 722 has a counterclockwise rotation tendency as shown in fig. 4. However, since the one-way pawl 723 is clamped on the one-way pawl 723 under the elastic action of the torsion spring, so that the driven turntable 722 can only rotate clockwise as shown in fig. 4, the driven turntable 722 is clamped and kept still;

when unlocking, the safety lock 700 changes from the number 1 to the number 2 as shown in fig. 6, the manual knob 725 is turned, so that the driving rotation shaft 721 drives the driven rotation disc 722 to rotate, specifically, with the rotation of the driving rotation shaft 721, the driving rotation end 721a will be pressed on the driven rotation post 724, and push the driven rotation disc 722 to rotate clockwise as shown in fig. 6, the driven rotation post 724 rotates from the upper left of the driving rotation shaft 721 to the right, during which the return spring 732 is further compressed. When the driven turning post 724 is located right above the driving rotating shaft 721 (the manual knob 725 points to a designated position), the driven turning post 724 is located at the "highest point", at this time, the return spring 732 is compressed to the limit, the connecting rod 736 is parallel to the sliding rod 731, the locking end 735 of the sliding rod 731 slides to the limit position, that is, the locking end 735 is no longer blocked by the locking groove 151, and the cabinet door 160 can be opened smoothly;

when the cabinet is locked, the manual knob 725 is directed to a specific position, the locking end 735 of the sliding rod 731 is at the limit position, the cabinet door 160 is covered on the cabinet body 150, and then the manual knob 725 is rotated again, so that the driving toggle end 721a continues to push the driven rotary disc 722 to rotate clockwise as shown in fig. 6, when the driven toggle column 724 crosses the "highest point" (i.e., the driven toggle column 724 crosses over the right upper side of the driving rotary shaft 721 and is located on the upper right side), at this time, the original counterclockwise rotation trend of the driven rotary disc 722 is changed into the clockwise rotation potential energy, the driven rotary disc 722 rotates clockwise and is not clamped by the one-way pawl 723, the elastic potential energy of the return spring 732 is released rapidly, the sliding rod 731 is pushed to slide downward, and the locking end 735 of the sliding rod 731 is clamped by the locking groove 151 after sliding downward. At the same time, driven dial 722 rotates clockwise, and safety lock 700 changes from number 2 to number 3 as shown in fig. 6. When the driven dial post 724 rotates to a position right below the driving rotation shaft 721, the return spring 732 extends to the longest position. Due to inertia, the driven dial 722 will rotate, the driven dial 724 will rotate from right under the driving rotary shaft 721 to the upper left position again, the safety lock 700 will change from the number 3 to the number 1 as shown in fig. 6, and the return spring 732 will be compressed again to prepare for the next unlocking. Returning to the original state of the safety lock 700, the locking end 735 of the sliding rod 731 is still engaged with the locking groove 151, so that the locking operation of the safety lock 700 is completed.

It should be noted that only when the driven turning post 724 is located right above the driving rotation shaft 721 (the manual knob 725 points to a designated position), the locking end 735 of the sliding rod 731 is pulled to an extreme position, the locking end 735 cannot be held by the locking groove 151, and the cabinet door 160 can be opened smoothly. Moreover, in order to improve the unlocking difficulty of the safety lock 700, the safety lock 700 of the present invention has two interferences, specifically as follows: firstly, the driven turntable 722 can only rotate in one direction, but the driving rotating shaft 721 can rotate freely, only if the driving rotating shaft 721 rotates in a designated direction, the driving toggle end 721a can press the driven toggle column 724 and drive the driven turntable 722 to rotate, otherwise, even if the driving toggle end 721a presses the driven toggle column 724, the driven turntable 722 cannot overcome the clamping of the one-way pawl 723; secondly, when the manual knob 725 is rotated to a specified position in a specified direction, the locking end 735 of the sliding rod 731 is pulled to the limit position, the cabinet door 160 can be opened smoothly, and if the manual knob 725 passes the specified position during the rotation process, the safety lock 700 will respond quickly and reset to the initial state (the number 2 shown in fig. 6 is changed back to the number 1). Therefore, the unlocking difficulty of the safety lock 700 is improved, and only an operator familiar with the structure of the safety lock 700 can unlock the safety lock smoothly, so that the property safety of equipment is protected; moreover, the unlocking process of the safety lock 700 needs to be focused, and the operation of mistakenly opening the cabinet door 160 does not exist, so that the personal safety of workers is protected.

In this embodiment, as shown in fig. 5, the driven turntable 722 is a sector structure, so that the driven turntable 722 has the effect of a flywheel, and in the process of rapidly releasing the elastic potential energy of the return spring 732, the driven turntable 722 can obtain larger kinetic energy and convert the kinetic energy into the potential energy of the system in the process of resetting the safety lock 700 to the initial position, so that the movement of the safety lock 700 can be more stable.

In the locking process, in order to facilitate the operator to lock the cabinet door 160, simplify the locking step, and avoid the operation of rotating the manual knob 725 to a predetermined position, in one embodiment, as shown in fig. 7, the sliding assembly 730 further includes a movable lock pin 740, the sliding rod 731 is provided with a lock pin receiving groove 738, the movable lock pin 740 is movably received in the lock pin receiving groove 738 through a telescopic elastic member 741, and the movable lock pin 740 is provided with a locking inclined surface 742 and an anti-falling stopper 743.

After the movable lock pin 740 is arranged, an operator only needs to dial the manual knob 725 after unlocking to trigger the safety lock 700 to reset to the initial position, and then, when locking, the cabinet door 160 is directly pushed to cover the cabinet body 150, so that the cabinet can be locked. The specific process is as follows: at the beginning, as shown in fig. 7, the safety lock 700 is at the initial position, the movable lock pin 740 is in the extended state under the action of the elastic member 741, and the anti-falling stopper 743 is engaged with the wall of the lock pin accommodating groove 738 to prevent the movable lock pin 740 from falling off; subsequently, the safety lock 700 approaches the lock slot 151, the movable lock pin 740 is pressed against the lock slot 151, and since the movable lock pin 740 has the upper locking inclined surface 742, the movable lock pin 740 performs an avoiding action against the elastic force of the telescopic elastic member 741, and after the sliding rod 731 passes through the lock slot 151, the movable lock pin 740 is in an extended state again, and the movable lock pin 740 is clamped with the lock slot 151 to realize locking. The unlocking operation is the same as that described above, when the driven rotating column 724 is located at the "highest point", the movable lock pin 740 is no longer clamped with the lock groove 151, and at this time, the cabinet door 160 can be smoothly opened.

In conclusion, the environment-friendly air blowing type dust removing equipment 10 can remove dust of the processed parts, improve the working efficiency of dust removal and reduce the pollution of dust to the workshop environment.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
