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.

[0051] like Figure 1-4 As shown, the utility model discloses a door panel grinding machine, comprising:

[0052] The machine body 10 has a grinding cavity 100 for the door panel to pass through;

[0053] The grinding roller 101 is rotatably disposed in the grinding chamber 100, and a grinding area 101a is formed between adjacent grinding rollers 101;

[0054] A dust collecting device is provided on the machine body 10 and has a dust collecting end connected to the grinding chamber 100;

[0055] The conveying device is arranged in the grinding chamber 100 and is used to convey the door panel through the grinding area. The dust collecting device includes:

[0056] A dust suction structure 2, comprising an air jet end and a dust suction end;

[0057] The driving structure 3 is installed on the machine body 10 and is used to drive the dust collecting structure 2 to move back and forth;

[0058] The pump body assembly 4 is composed of an air supply pump 40 and a dust extraction pump 41. The air supply pump 40 supplies air to the jet end to form a jet flow, and the dust extraction pump 41 sucks dust through the dust suction end to form a suction flow;

[0059] Wherein, the dust suction structure 2 is distributed in the grinding chamber 100;

[0060] When the pump assembly 4 and the driving structure 3 are started, the dust suction structure 2 moves on both sides of the door body, and the jet flow is sprayed toward the door panel and cleans the door panel before being sucked away by the exhaust air flow.

[0061] In this embodiment, the conveying device is composed of a plurality of conveying rollers 103 rotatably connected to the grinding chamber. The driving method of the grinding roller 101 and the conveying roller 103 in this embodiment is a relatively mature prior art, and therefore, it will not be described in detail in this embodiment.

[0062] In this embodiment: the dust suction structure 2 includes:

[0063] The dust collecting body 20 has an air injection chamber 20a and a dust collecting chamber 20b;

[0064] The buffer zone 20c is formed concavely on the wall of the dust collecting chamber 20b and has a curved surface.

[0065] In this embodiment: the driving structure 3 includes:

[0066] At least two screw shafts 30 are rotatably disposed in the grinding chamber 100;

[0067] The screw bearing seat 31 is arranged on the screw shaft 30 in a matching manner;

[0068] The mounting seat 32 is fixedly disposed between the screw rod bearing seats 31;

[0069] The dust collecting body 20 is fixedly mounted on the mounting seat 32 .

[0070] In this embodiment, the motor 30 a driving the screw shaft 30 to rotate may be disposed in a chassis 30 b , and the chassis 30 b is mounted on the machine body 10 .

[0071] refer to Figure 1-4 , the principle of this embodiment is:

[0072] When grinding the door panel, the door panel is fed into the grinding chamber from one end, conveyed by the conveying rollers through the grinding area formed between the grinding rollers, and then moved out from the outlet on the other side of the grinding chamber after being grinded by the grinding rollers.

[0073] After sanding is completed and before the door panel is removed, the driving structure of the utility model (a screw structure, which may have two screw structures, so as to achieve the purpose of driving the mounting seat to move) drives the dust suction structure on the mounting seat to reciprocate on or under the door panel 1000. When the dust suction structure moves, the air supply pump and the dust extraction pump are started, and the air supply pump supplies air to the jet chamber, and continuously sprays air to the door panel through the jet chamber to clean the door chips on the door panel. After passing through the door panel, the airflow ejected from the jet chamber is reflected to the dust suction end of the dust suction chamber, and the wood chips are sent into the dust suction chamber. When the dust extraction pump is pneumatic, the wood chips on the door panel can be continuously extracted, thereby completing the dust extraction work.

[0074] It is worth noting that the dust buffer zone is provided in the dust suction chamber of this embodiment to form a curved surface for buffering the reflected airflow and guiding it to move toward the air outlet end of the dust suction chamber, so that the airflow guided and reflected from the door panel into the dust suction chamber flows more smoothly in the dust suction chamber.

[0075] In this embodiment, the air supply pump and the dust extraction pump may be connected to the air injection chamber or the dust suction chamber via an air pipe (not shown).

[0076] Embodiment 2 is different from Embodiment 1 in that

[0077] like Figure 5-6 As shown, in this embodiment, the dust collecting body 20 includes:

[0078] The main body 200 has the jet chamber 20a and the dust suction chamber 20b;

[0079] A spacing adjustment structure having a telescopic end capable of telescopic movement;

[0080] Wherein, the body 200 is fixed on the telescopic end, and the spacing adjustment structure has an air inlet end, an air outlet end and an air cavity;

[0081] When the air cavity 50 is inflated through the air inlet end, the telescopic end drives the body 200 to approach the door panel 1000;

[0082] When the air cavity 50 is exhausted through the exhaust end, the telescopic end drives the body 200 away from the door panel 1000 and sprays the air flow toward the screw shaft 30 .

[0083] In this embodiment, the spacing adjustment structure includes:

[0084] Regulator 60;

[0085] The movable plate 60a moves in the adjusting body 60 and separates the air cavity 50 and the spring cavity 52 in the adjusting body 60;

[0086] An air intake check valve 61 is mounted on the regulating body 60 and communicated with the air cavity 50;

[0087] The exhaust control valve 62 is mounted on the regulating body 60 and communicated with the air cavity 50;

[0088] The return spring 63 is installed in the spring cavity 52, and its two ends are respectively against the cavity wall of the spring cavity 52 and the movable plate 60a;

[0089] A connecting shaft 64a, connecting the movable plate 60a and the body 200;

[0090] The regulating body 60 is fixed on the mounting seat 32 , and an air nozzle 62 b connected to the exhaust control valve 62 via an air pipe 62 a is provided on the mounting seat 32 .

[0091] In this embodiment, the air outlet of the air supply pump is connected to an air supply main pipe 70, and a three-way control valve 71 is installed at the end of the air supply main pipe 70. The two outlets of the three-way control valve 71 are respectively connected to the jet chamber 20a and the air intake check valve 61 through the air supply branch pipe 72.

[0092] refer to Figure 5-6 , the principle of this embodiment is:

[0093] When the driving structure controls the movement of the dust collector, the three-way control valve controls the air supply to the air cavity to make the dust collector descend. When the exhaust control valve is opened, the gas in the air cavity is discharged and the dust collector is controlled to rise by the return spring. Thus, the distance between the jet end of the jet cavity on the dust collector and the dust end of the dust cavity and the door panel is adjusted, so as to better remove impurities such as wood chips on the door panel.

[0094] It should be noted that when the gas in the air cavity is discharged, it is sent to the air nozzle through the air pipe on the exhaust control valve. The air nozzle sprays the gas toward the screw shaft and cleans the screw shaft, thereby ensuring that the screw bearing seat moves smoothly on the screw shaft.

[0095] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
