Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment for painting parts, and in particular to a masking box for manual painting of parts. Background Technology

[0002] After the parts are hand-made, they need to be painted. Currently, when painting parts by hand, the paint sprayed from the spray gun tends to splatter everywhere. To solve this problem, it is often necessary to mask specific areas around the parts to prevent them from being painted. However, traditional hand-painting of parts usually relies on a simple box for masking. Therefore, hand-painting of parts still has the following shortcomings:

[0003] An exhaust fan is installed on the base of the enclosure to expel the paint mist outdoors. This will cause some of the paint mist to be dispersed in the air again, causing pollution to the atmospheric environment. Moreover, the harmful substances in the paint mist will also pose a threat to the health of the operators. Some of the paint mist will adhere to the exhaust fan, which will affect the dynamic balance of the fan over time, causing abnormal operation of the fan and generating noise and vibration problems.

[0004] Secondly, when painting handmade parts, the spraying position needs to be manually switched, which not only contaminates the hands but also prolongs the painting time. Utility Model Content

[0005] This utility model discloses a masking box for spray painting handmade parts. The operator turns on the power switch of the electric motor, places the handmade parts to be painted on top of the rotating disk, and the electric motor drives the rotating disk to start rotating. The rotating disk drives the parts to be painted placed on it to rotate. The power of the fan inside the drainage housing is turned on, and the fan starts to run, generating suction. The operator sprays the rotating parts inside the masking box. During the spraying process, the fan inside the drainage housing sucks in the excess paint mist generated during spraying.

[0006] In a first aspect, this disclosure provides a masking box for hand-painted parts, specifically comprising: a base; a masking box bolted to the upper part of the base; a hinged protective cover mounted on the outer side of the masking box with a pin; an observation port on the upper part of the protective cover; a snap-fit ​​drainage housing mounted in the middle of the base; a set of bolt mounting holes on one side of both the masking box and the drainage housing; a snap-fit ​​stabilizing plate mounted on the outer side of the drainage housing; an auxiliary positioning structure mounted above the stabilizing plate, the auxiliary positioning structure consisting of positioning bolts and ball bearings; and a rotating mechanism mounted in the middle of the base and the masking box, the rotating mechanism consisting of an electric motor and a rotating disk.

[0007] Furthermore, the bottom of the shield box is provided with a set of positioning plates with bolt mounting holes. A set of positioning grooves corresponding to the positioning plates are opened on one side of the base at the upper position. The positioning plates are installed inside the positioning grooves. A set of bolt mounting holes and a set of threaded grooves are opened in the middle of the positioning grooves. A locking bolt is inserted inside the bolt mounting holes.

[0008] Furthermore, a mounting hole is provided in the middle of the shielding box. The mounting hole is cylindrical, and the drainage housing passes through the interior of the mounting hole and a sealing ring is installed on the outside.

[0009] Furthermore, a set of evenly distributed annular grooves are formed on the outer surface of the sealing ring.

[0010] Furthermore, a positioning strip is provided in the middle of one side of the drainage shell. The positioning strip has a T-shaped structure, and a set of positioning grooves is opened in the middle of one side of the stabilizing plate. The positioning strip extends into the interior of the positioning strip.

[0011] Furthermore, a mounting hole is provided on each side of the stabilizing plate, and a filter screen with a positioning ring is installed inside the mounting hole.

[0012] Furthermore, a threaded hole is formed at the top of the stabilizing plate. The threaded hole has a cylindrical stepped structure. A ball bearing is installed at the small diameter position of the threaded hole, and a positioning bolt is installed at the large diameter position of the threaded hole. A support spring is installed between the ball bearings.

[0013] Furthermore, a stabilizing hole is formed in the middle of the base, an electric motor is installed inside the stabilizing hole, a rotating disk is installed above the drive shaft of the electric motor, and a stabilizing groove is formed at the bottom of the base. The stabilizing groove is a circular structure, and the bottom of the rotating disk extends into the interior of the stabilizing ring.

[0014] This utility model provides a masking box for spray painting handmade parts, which has the following beneficial effects:

[0015] A shielding box is installed to cover the paint sprayed on the hand-painted parts. A base is installed to stabilize the shielding box. A sealing ring is installed on the base of the drainage shell to seal and stabilize the assembly position of the threaded tube and the drainage shell, preventing paint mist leakage. The connection is also stable and can meet the needs of long-term operation.

[0016] An internal fan, combined with a filter on the positioning plate, effectively absorbs and filters excess paint mist generated during spraying. This function prevents excess paint mist from being dispersed back into the air, improving the working environment, reducing health hazards to operators, and preventing paint from sticking to the fan blades, ensuring normal fan operation and extending the fan's service life.

[0017] The horizontally moving positioning plate moves the filter to be replaced out of the working position, while the filter on the other side can continue to work, achieving uninterrupted filtration.

[0018] The protective cover is hinged to the outside of the shielding box by a pin. When closed, it can prevent dust and debris from entering the shielding box, reducing the frequency of internal cleaning.

[0019] The electric motor and rotating plate work together to rotate the handmade parts, allowing for better painting of different parts of the handmade parts and shortening the painting time. Attached Figure Description

[0038] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0039] Example 1: Please refer to Figures 1 to 7 :

[0040] This utility model proposes a masking box for painting handmade parts, including: a base 1, a masking box 2 installed on the upper part of the base 1 with bolts, a set of positioning plates with bolt mounting holes at the bottom of the masking box 2, a set of positioning grooves corresponding to the positioning plates opened on the upper part of one side of the base 1, the positioning plates are installed inside the positioning grooves, a set of bolt mounting holes and a set of threaded grooves are opened in the middle of the positioning grooves, a locking bolt is inserted inside the bolt mounting holes, and the locking bolt is threadedly connected to the threaded grooves after installation. Therefore, after the locking bolt is installed, it can achieve the effect of stable assembly of the base 1 and the masking box 2. The setting of the positioning plate and the positioning groove can achieve the effect of quick positioning of the assembly position of the base 1 and the masking box 2. A set of evenly distributed annular grooves are opened on the outer side of the sealing ring 401. When the worker selects a threaded pipe corresponding to the maximum diameter of the sealing ring 401, after installing one end of the existing threaded pipe on the outside of the sealing ring 401, the sealing ring 401 achieves the effect of sealing and stabilizing the assembly position of the threaded pipe and the drainage shell 4.

[0041] In this embodiment of the disclosure, reference is made to Figures 1 to 7As shown, a hinged protective cover 3 is installed on the outer side of the shielding box 2 with a pin. An observation port is opened on the top of the protective cover 3, allowing staff to easily observe the interior of the shielding box 2. After the protective cover 3 is lowered, it provides dust protection and facilitates the assembly of debris inside the shielding box 2, reducing the frequency of cleaning the interior of the shielding box 2. A snap-fit ​​drainage housing 4 is installed in the middle of the base 1. A set of bolt mounting holes are opened on one side of both the shielding box 2 and the drainage housing 4. Staff need to install a set of existing bolts at the bolt mounting holes. The bolt type selected by the staff needs to match the bolt type. With the bolts installed in the corresponding holes, the shielding box 2 and the diversion housing 4 are securely assembled after installation. Referring to the existing fan structure, the staff installs a fan inside the diversion housing 4. A mounting hole is made in the middle of the shielding box 2. The mounting hole is cylindrical. The diversion housing 4 passes through the inside of the mounting hole and a sealing ring 401 is installed on the outside. The sealing ring 401 is made of rubber material commonly used in pipe sealing. Due to the elastic rubber structure of the sealing ring 401, the sealing ring 401 can be firmly installed on the outside of the diversion housing 4 after installation.

[0042] In this embodiment of the disclosure, reference is made to Figures 1 to 7 As shown, a snap-fit ​​stabilizing plate 5 is installed on the outer side of the drainage housing 4. A positioning strip with a T-shaped structure is located in the middle of one side of the drainage housing 4. A set of positioning grooves is opened in the middle of one side of the stabilizing plate 5, extending into the interior of the positioning strip. Therefore, the positioning strips cooperate to achieve vertical and circumferential positioning of the drainage housing 4 and the stabilizing plate 5, allowing the stabilizing plate 5 to be stably adjusted laterally in conjunction with the positioning grooves. A mounting hole is opened on each side of the stabilizing plate 5, and a filter screen 501 with a positioning ring is installed inside the mounting hole. The mounting hole achieves the effect of hiding and positioning the filter screen 501. When the filter screen 501 and... After the internal connection of the flow-inlet housing 4 is established, the excess paint sprayed on the fan parts inside the flow-inlet housing 4 is collected. At this time, the filter screen 501 collects the excess paint, preventing the excess paint from being dispersed into the air again, and solving the problem of excess paint sticking to the fan blades. The specific filtration structure of the filter screen 501 is selected by the staff according to the needs of the conventional structure for filtering dust in the existing technology. The setting of the mounting hole facilitates the installation and replacement of the filter screen 501. Combined with the positioning strip of the flow-inlet housing 4, the effect of switching the filter screen 501 is achieved by moving the stabilizing plate 5. Therefore, after one filter screen 501 is removed, the other filter screen 501 continues to filter the sprayed paint.

[0043] In this embodiment of the disclosure, reference is made to Figures 1 to 7As shown, an auxiliary positioning structure 6 is installed above the stabilizing plate 5. The auxiliary positioning structure 6 consists of a positioning bolt 601 and a ball bearing 602. A threaded hole is opened above the stabilizing plate 5. The threaded hole has a cylindrical stepped structure. A ball bearing 602 is installed at the small diameter position of the threaded hole. After installation, the ball bearing 602 can slide inside the threaded hole. A positioning bolt 601 is installed at the large diameter position of the threaded hole. A support spring is installed between the balls bearing 602. The support spring provides elastic support to the balls bearing 602, so that the balls bearing 602 and one side of the drain housing 4 are in elastic contact. The balls bearing 602 cooperate with the spring to assist in locking the movement position of the stabilizing plate 5. After installation, the positioning bolt 601 is threadedly connected to the threaded hole. Therefore, after the positioning bolt 601 is installed, it positions one end of the spring, so that the spring can effectively support the balls bearing 602.

[0044] In this embodiment of the disclosure, reference is made to Figures 1 to 7 As shown, a rotating mechanism 7 is installed in the middle of the base 1 and the shielding box 2. The rotating mechanism 7 consists of an electric motor 701 and a rotating disk 702. A stabilizing hole is opened in the middle of the base 1, and an electric motor 701 is installed inside the stabilizing hole. The electric motor 701 is installed according to the riveting structure of the prior art, so that the stabilizing hole can stabilize the installed electric motor 701. A rotating disk 702 is installed above the drive shaft of the electric motor 701. The operator refers to the wedge key structure in the prior art to circumferentially position the assembly position of the drive shaft and the rotating disk 702, so that the electric motor 701 can rotate the disk 702 after the power is turned on. A stabilizing groove is opened at the bottom of the base 1. The stabilizing groove is a ring structure, and the bottom of the rotating disk 702 extends into the inside of the stabilizing ring. The operator needs to leave a gap of one millimeter between the stabilizing groove and the rotating disk 702. The stabilizing groove achieves the effect of stabilizing the lateral position of the rotating disk 702, so that the rotating disk 702 rotates stably. The setting of the stabilizing groove also prevents the drive shaft of the electric motor 701 from bending and deforming.

[0045] Example 2, based on Example 1, with reference to Figures 1 to 7 As shown, the materials of the base 1 and the shielding box 2 can be selected from existing technologies as needed. The materials of the base 1 and the shielding box 2 can be metal, plastic, or glass.

[0046] Example 3, based on Example 1, with reference to Figures 1 to 7 As shown, a set of control switches is installed on the base 1, and the control switches are electrically connected to the fan and electric motor 701 respectively, referring to the conventional structure of the prior art.

[0047] The working principle of this embodiment:

[0048] The installation steps for base 1 and shield box 2 are as follows: First, the operator aligns the positioning plate with bolt mounting holes at the bottom of shield box 2 with the positioning groove on the upper side of one side of base 1 and inserts it into the positioning groove to achieve initial positioning. Then, the locking bolt is inserted into the bolt mounting hole in the middle of the positioning groove so that it is threadedly connected with the threaded groove. The locking bolt is then tightened with a tool to ensure that base 1 and shield box 2 are stably assembled.

[0049] The installation steps for the drainage housing 4 are as follows: The operator passes the drainage housing 4 through the cylindrical structure mounting hole in the middle of the shielding box 2, uses the elasticity of the sealing ring 401 to achieve sealing and fixation, installs the sealing ring 401 on the outside of the drainage housing 4 to ensure that it fits tightly, aligns the bolt mounting holes on one side of the shielding box 2 and the drainage housing 4, selects the appropriate type of bolt, and uses tools to install it in the bolt mounting hole position to make the shielding box 2 and the drainage housing 4 firmly connected.

[0050] The installation steps for the stabilizing plate 5 and the filter screen 501 are as follows: The operator aligns the T-shaped positioning strip on one side of the drainage housing 4 with the positioning groove on one side of the stabilizing plate 5 to achieve the vertical and circumferential positioning of the drainage housing 4 and the stabilizing plate 5. The filter screen 501 with positioning rings is installed in the mounting holes on both sides of the stabilizing plate 5.

[0051] The installation steps for the auxiliary positioning structure 6 are as follows: The operator installs the ball bearing 602 at the small diameter position of the threaded hole above the stabilizing plate 5 to ensure that the ball bearing 602 can slide in the threaded hole; the positioning bolt 601 is installed at the large diameter position of the threaded hole, and the support spring is installed between the ball bearing 602 so that the support spring provides elastic support for the ball bearing 602. The positioning bolt 601 positions one end of the spring to ensure that the spring effectively supports the ball bearing 602 and makes the ball bearing 602 elastically contact one side of the drainage housing 4.

[0052] The installation steps of the rotating mechanism 7 are as follows: The operator installs the electric motor 701 in the stabilizing hole in the middle of the base 1 and fixes it using the existing riveting structure to ensure that the stabilizing hole is stable for the electric motor 701; referring to the wedge key structure in the existing technology, the drive shaft of the electric motor 701 is assembled with the rotating disk 702 to achieve circumferential positioning, and it is confirmed that the bottom of the rotating disk 702 extends into the stabilizing groove of the bottom ring structure of the base 1, and a one-millimeter gap is reserved between the two.

[0053] The operator opens the protective cover 3 on the outside of the shield box 2, which is hinged by a pin, to ensure that the protective cover 3 opens smoothly without any jamming.

[0054] The operator connects the electric motor 701 to the power supply according to the conventional structure of the existing technology, ensuring that the wiring is correct and there are no short circuits or open circuits. At the same time, the operator connects the power supply of the fan inside the drain housing 4 according to the conventional structure of the existing technology.

[0055] The operator turns on the power switch of the electric motor 701, places the handmade parts to be sprayed on top of the rotating disk 702, and the electric motor 701 drives the rotating disk 702 to start rotating, using the rotating disk 702 to drive the parts to be sprayed placed on it to rotate.

[0056] Turn on the power to the fan inside the drainage housing 4. The fan will start running and generate suction.

[0057] The operator sprays the rotating parts inside the shielding box 2. During the spraying process, the fan inside the drainage housing 4 sucks in the excess paint mist generated during spraying.

[0058] When the inhaled paint mist passes through the filter screen 501 on the stabilizing plate 5, the filter screen 501 filters and collects the excess paint to prevent it from being dispersed into the air again, and at the same time prevents the paint from sticking to the fan blades.

[0059] Close the protective cover 3 and check the inside of the shield box 2 through the observation port on the top of the protective cover 3. If there are paint stains or dust on the protective cover 3, it can be cleaned regularly.

[0060] When the filter screen 501 needs to be replaced, move the stabilizing plate 5 laterally to move the side of the filter screen 501 that needs to be replaced out of the working position, so that the filter screen 501 on the other side can continue to work. Take out the filter screen 501 that needs to be replaced from the mounting hole of the stabilizing plate 5, and install the new filter screen 501. After the installation is completed, move the stabilizing plate 5 back to its original position and stabilize it again by the auxiliary positioning structure 6.
