Description

Technical Field

[0001] The utility model relates to the technical field of powder coating processing auxiliary equipment, in particular to a coating dust collecting device. Background Art

[0002] Powder coating refers to a new type of solvent-free 100% solid powder coating. It is made by mixing, crushing and sieving film-forming resins, additives, pigments, fillers, etc. The coating construction requires electrostatic spraying and baking to form a film. It has the characteristics of being solvent-free, pollution-free, recyclable, environmentally friendly, saving energy and resources, reducing labor intensity and having high mechanical strength of the coating film.

[0003] During the powder coating production process, dust will float into the air. If it is not handled in time, it will not only affect the production environment, but the high concentration of the floating dust will also affect the health of the workers. If the exhaust mechanism of the assembly is directly used, its adsorption capacity for the area with a high local powder layer concentration is weak and cannot produce obvious effect. Therefore, a coating powder layer collection device is still needed to collect the powder layer in some areas in a centralized manner. After some collection devices have been used for a period of time, a lot of impurities have accumulated. If they are not cleaned in time, it will also affect the subsequent dust collection.

[0044] Example

[0045] During the production process of powder coatings, dust will float into the air. If it is not handled in time, it will not only affect the production environment, but also the high concentration of the floating dust will affect the health of the workers. If the exhaust mechanism of the assembly is directly used, its adsorption capacity for the local area with high powder concentration is weak and cannot produce obvious effects. Therefore, a coating powder layer collection device is still needed to collect some areas in a centralized manner. After some collection devices have been used for a period of time, more impurities are accumulated. If they are not cleaned in time, it will also affect the subsequent dust collection. In order to solve the above technical problems, this embodiment provides the following technical solutions:

[0046] For details, see Figure 1-7 The present embodiment provides a coating dust collection device, including a mobile base 10, a collection box 20 is provided on the mobile base 10, an exhaust fan 30 is provided on the collection box 20, and the exhaust fan 30 is connected to the inside of the collection box 20; the exhaust fan 30 is connected to a collection pipe 31, and a suction head 40 is provided at one end of the collection pipe 31 away from the exhaust fan 30;

[0047] Specifically, the suction head 40 includes an outer shell 41, a filter 42 and a cleaning assembly. The outer shell 41 forms a first cavity connected to the material collecting pipe 31. The filter 42 is arranged at one end of the outer shell 41 away from the material collecting pipe. The cleaning assembly can be rotatably arranged on the filter 42. The cleaning assembly includes a clamping joint 433, a connecting rod 432 fixedly connected to the clamping joint 433, and a brush body module 431 arranged on the connecting rod 432.

[0048] Furthermore, a first vertical plate 11 is provided on the mobile base 10, a fixing seat 14 is provided on the first vertical plate 11, a first rotating motor 51 is provided on the fixing seat 14, a clamping block 52 is provided at the driving end of the first rotating motor 51, and a clamping groove 434 adapted to the clamping block 52 is formed on the clamping joint 433;

[0049] The first rotary motor 51 is suitable for driving the cleaning assembly to rotate through the clamping block 52 and the clamping slot 434;

[0050] In the above scheme, after the staff moves the mobile base 10 to the designated point, the suction head 40 is directed to the appropriate position, and the exhaust fan 30 is turned on to generate negative pressure. The dust passes through the filtering effect of the filter 42 and enters the outer shell 41, and then enters the collection box 20 through the collection pipe 31 to collect the dust centrally. The staff can move the entire device to a key position at any time through the mobile base 10 for centralized collection. After a period of use, some impurities are attached to the filter 42. At this time, the suction head 40 can be moved and placed under the fixed seat 14, and the clamping joint 433 is aligned with the clamping block 5. 2. Insert the card connector 433 into the card slot 434 of the card block 52, and then start the first rotating motor 51. The first rotating motor 51 drives the card block 52 to rotate, and the card block 52 drives the card connector 433 to rotate to drive the connecting rod 432 to rotate. The rotation of the connecting rod 432 drives the brush body module 431 to rotate to clean the impurities on the filter 42. At this time, the exhaust fan 30 is turned on synchronously. This solution further improves the structure of the suction head 40, and cooperates with the first rotating motor 51, the card block 52 and the cleaning component to quickly clean the filter 42, so as to avoid excessive accumulation of impurities and affect the subsequent dust collection.

[0051] For details, see Figure 7 In one embodiment, the axial part of the filter 42 has an installation position, which is used to fix the card joint 433. A bearing 435 can be further arranged at the assembly position of the card joint 433, so as to ensure the stable rotation of the card joint 433; it can be understood that the implementation method of the rotatable setting belongs to a relatively mature technology in the prior art, and the above is only one of the methods listed in this application.

[0052] For details, see Figure 2-3 The slot 434 includes a cylindrical portion 4341 and a strip portion 4342 extending radially along the cylindrical portion 4341;

[0053] In the above solution, when the columnar portion 4341 and the strip portion 4342 cooperate to make the clamping joint 433 and the clamping block 52 engage, the clamping block 52 can stably drive the clamping joint 433 to rotate.

[0054] Specifically, the brush body module 431 includes a fixed shaft 4311 connected to the connecting rod 432 and a brush roller 4312 rotatably disposed on the fixed shaft 4311, and the brush roller 4312 is suitable for abutting against the filter screen 42;

[0055] In the above scheme, the rotation of the clamping block drives the connecting rod 432 to rotate, and the rotation of the connecting rod 432 drives the fixed shaft 4311 to rotate, and the brush roller 4312 abuts against the filter screen 42. When the connecting rod 432 rotates, the brush roller 4312 is rotatably arranged on the fixed shaft 4311, and can form a certain rotation under the action of the relative friction force with the filter screen 42; it can be understood that the brush roller 4312 can clean the filter screen 42 regardless of whether it rotates or not.

[0056] For details, see Figure 4 The brush body module 431 includes a fixed shaft 4311 connected to the connecting rod 432 and a brush roller 4312 rotatably disposed on the fixed shaft 4311, and the brush roller 4312 is suitable for abutting against the filter screen 42;

[0057] In the above scheme, the rotation of the clamping block drives the connecting rod 432 to rotate, and the rotation of the connecting rod 432 drives the fixed shaft 4311 to rotate, and the brush roller 4312 abuts against the filter screen 42. When the connecting rod 432 rotates, the brush roller 4312 is rotatably arranged on the fixed shaft 4311, and can form a certain rotation under the action of the relative friction force with the filter screen 42; it can be understood that the brush roller 4312 can clean the filter screen 42 regardless of whether it rotates or not.

[0058] Specifically, a first through hole is provided on the outer shell 41, and a first latch 61 suitable for being inserted into the first through hole is also provided. The first latch 61 is located on the rotation path of the brush roller 4312;

[0059] In the above scheme, during use, if you want to completely avoid the cleaning component from rotating during normal dust removal, you can insert the first pin 61 into the first through hole to prevent the brush roller 4312 from moving; it is understandable that the user can choose whether to insert the first pin 61 according to actual use needs. If the rotation of the cleaning component is not strong during use and has little effect on normal dust removal, you can choose not to insert the first pin 61.

[0060] For details, see Figure 2 A fixing block 44 is provided on the outer wall of the outer shell 41, and a first through slot 441 is provided on the fixing block 44 along the vertical direction;

[0061] For further information, see Figure 5 A receiving groove 141 suitable for receiving the fixing block 44 is provided on the side wall of the fixing seat 14, and a second through groove 142 communicating with the receiving groove 141 is provided on the fixing seat 14 in a vertical direction;

[0062] Specifically, when the fixing block 44 is inserted into the receiving groove 141, the first through groove 441 is connected with the second through groove 142;

[0063] It also includes a second latch pin 62 adapted to be inserted into the first through slot 441 and the second through slot 142;

[0064] In the above scheme, when it is necessary to fix the suction head 40, first insert the fixing block 44 on the outer shell 41 into the accommodating groove 141 of the fixing seat 14, and then insert the second pin 62 into the second through groove 142 and the first through groove 441 after aligning the first through groove 441 and the second through groove 142. At this time, the second pin 62 locks the fixing block 44 to ensure the stable connection between the suction head 40 and the fixing seat 14; when it is necessary to use the suction head 40 freely, pull out the second pin 62, and then the suction head 40 can be smoothly pulled out for flexible use.

[0065] Specifically, the first latch 61 and the second latch 62 each include a rod body 622 and a retaining ring 621 extending radially along the rod body 622;

[0066] In the above solution, when the first latch 61 and the second latch 62 are in use, the retaining ring 621 can realize a retaining effect, so that the latch stops after being inserted into a suitable position, which can facilitate subsequent removal.

[0067] Specifically, the fixing seat 14 is rotatably and adjustably arranged on the first vertical plate 11;

[0068] In one of the embodiments, the rotational fixed adjustment can be achieved by means of an adjusting bolt 111, that is, when the rotation angle adjustment is required, the adjusting bolt 111 is loosened, and after adjusting to a suitable angle, the adjusting bolt 111 is tightened; it can be understood that the method of achieving adjustable rotation angle by means of bolts is widely used in the prior art and is a technology that is easily acquired by those skilled in the art, so this embodiment will not be further elaborated on.

[0069] In the above scheme, the fixed seat 14 is rotatably adjusted on the first vertical plate 11, that is, the rotation angle of the fixed seat 14 is adjustable, and the direction angle of the suction head 40 fixed on the fixed seat 14 can also rotate with the rotation of the fixed seat 14, thereby providing more flexibility for practical applications.

[0070] For details, see Figure 6 The exhaust fan 30 is provided with a feeding pipe 21 in the collecting box 20, and a collecting bag 22 is provided on the outer cover of the feeding pipe 21;

[0071] In the above scheme, the dust extracted by the exhaust fan 30 passes through the collection pipe 31 and then enters the collection bag 22 through the feeding pipe 21. The dust is collected in the collection belt, which can effectively improve the collection efficiency, provide convenience for the staff during the collection process, and improve work efficiency.

[0072] For details, see Figure 1, a movable roller is provided at the bottom of the movable base 10;

[0073] Furthermore, a second vertical plate 12 is provided on the mobile base 10 at a side of the collection box 20 away from the first vertical plate 11, and a handrail 121 is provided on the second vertical plate 12;

[0074] In the above solution, in actual use, the staff can control the movement of the entire mobile base 10 through the handrail 121, and the moving rollers provide a flexible movement basis for the mobile base 10.
