Description

Technical Field

[0001] The invention relates to the technical field of surface spray painting, and more specifically, to a surface spray painting device for a housing component of an electric tool. Background Art

[0002] The housing component of the power tool is an important part of the power tool. It mainly supports and connects the motor, transmission mechanism, switch, handle and accessories, making the power tool a complete entity. In order to improve the painting efficiency of small power tool housing components, the staff uses roller spraying to spray the power tool housing components.

[0003] The existing device adds components into the device, then drives the components to tumble by rotating, and continuously sprays the surface of the components through the nozzle. After a preset time, the material is evenly sprayed and poured out. This method solves the problem of low efficiency of traditional arrangement of components and then spraying them one by one. However, the improved method still has the following problems: Since multiple components are added to the device at the same time, in order to ensure the uniformity of the spraying effect, the staff adds small balls into the device. During the tumbling process, the small balls roll on the surface of the components to achieve the purpose of complete spraying. However, this method can only spray one component. If multiple types of components are added, the different volumes and shapes of different components during tumbling will cause inconsistent tumbling heights of the components, some components will tumble too fast, and the spraying time will be long. In addition, adding small balls to multiple components will also cause inconsistent tumbling heights and uneven spraying. Summary of the invention

[0004] In view of the shortcomings of the prior art, the object of the present invention is to provide a device for spraying paint on the surface of a housing component of an electric tool.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a surface spray paint processing device for a power tool housing component, comprising a main body component, the main body component comprising a frame, a swing component is installed inside the frame, a conical bin is installed on the top of the swing component, a door body, a spray component and a drive motor are installed at the end of the conical bin, the drive motor is located at the circular part of the end of the conical bin, a rotating component is installed inside the conical bin, an adjusting component is installed at the inner center position of the rotating component, the output end of the drive motor is connected to the adjusting component, and a processing component is installed on the outer side wall of the adjusting component.

[0006] The processing component includes a first mesh plate and a sorting mechanism, the first mesh plate and the sorting mechanism are both installed on the outer side wall of the adjusting component, the sorting mechanism includes a second mesh plate installed on the outer side wall of the adjusting component, a groove is opened in the middle of the side of the second mesh plate close to the adjusting component, a third mesh plate is hinged inside the groove, the third mesh plate is connected to the inner wall of the groove through a rotating column, the outer wall of the rotating column is sleeved with a torsion spring, the two ends of the torsion spring are respectively connected to the inner wall of the groove and the side wall of the third mesh plate, micro-limit push rods are installed on both sides of the second mesh plate, multiple grids of the second mesh plate are connected with connecting blocks, and a top block is installed on the side of the connecting block close to the first mesh plate.

[0007] The present invention is further configured as follows: the main body component also includes a collection box installed at the bottom of the front surface of the frame, a filter screen is horizontally installed on the top of the collection box, and the filter screen is located directly below the conical bin.

[0008] The present invention is further configured as follows: a heater is installed on one side of the frame, the air outlet of the heater is connected to an exhaust duct, the end of the exhaust duct away from the heater is connected to the side wall of the conical bin, and the connection between the exhaust duct and the conical bin is arranged on the same side as the door body.

[0009] By adopting the above technical solution, the heater is equipped with a fan. When the fan rotates, it will draw the cold air in the room into the heater. When the cold air drawn into the heater passes through the heating element, the cold air absorbs heat and becomes hot air. Then, the hot air is blown out of the heater through the air outlet under the push of the fan. When the parts inside the conical bin are ready for painting, the hot air generated by the heater is first discharged to the inside of the conical bin through the exhaust pipe, and then the inside of the conical bin is preheated. When the appropriate temperature is reached, the staff will spray the parts. In the spraying process, the hot air can quickly dry the paint sprayed on the surface of the parts, thereby improving the spraying efficiency.

[0010] The present invention is further configured as follows: the swing assembly includes a supporting platform installed inside the frame and located at the side wall of the collection box, and a servo motor installed on the top of the supporting platform, the output end of the servo motor is connected to a swing rod, the outer side wall of the swing rod is installed with a U-shaped frame, the top of the U-shaped frame is installed with a connecting rod, and the connecting rod extends from one end of the U-shaped frame to the end position of the conical bin.

[0011] The present invention is further configured as follows: a lifting cylinder is hingedly installed on the top of the support platform, the piston rod end of the lifting cylinder is hingedly connected to the bottom of the U-shaped frame, and the hinge point is located at one end of the U-shaped frame away from the servo motor.

[0012] The present invention is further configured as follows: the rotating assembly includes a rotating motor installed at the bottom of the U-shaped frame and a rotating shaft connected to the output end of the rotating motor, one end of the rotating shaft passes through the bottom center point of the conical bin and extends to the interior of the conical bin, the end of the rotating shaft away from the rotating motor is connected to a conical bucket, the conical bucket is located inside the conical bin, and the adjusting assembly is installed at the center of the inner wall of the conical bucket.

[0013] By adopting the above technical scheme, the servo motor drives the swing arm to rotate, thereby driving the U-shaped frame and the connecting rod to swing. The connecting rod is used to assist in supporting the conical bin. When the U-shaped frame and the connecting rod swing, the conical bin swings synchronously, thereby being able to adjust the angle of the conical bin, that is, the conical bin is in an inclined upward state during the loading and painting process, and is in an inclined downward state during the unloading process. The lifting cylinder assists in supporting the U-shaped frame, that is, when the U-shaped frame and the connecting rod support and swing the conical bin, the U-shaped frame is assisted and lifted by the lifting cylinder to avoid deformation of the U-shaped frame due to the gravity of the conical bin.

[0014] The rotating motor drives the rotating shaft and the conical bucket to rotate. When the parts are placed inside the conical bin, they are first received by the conical bucket. When the conical bucket rotates, the parts are lifted along with the rotation of the conical bucket. When the parts are lifted to a certain height, they slide down due to gravity, that is, the parts that roll to the highest position slide to the middle of the pile, and so on. This reciprocating process is repeated to achieve the effect of rolling the parts.

[0015] The present invention is further configured as follows: the spraying assembly includes a bracket installed at the end of the conical bin, one end of the bracket extends to the interior of the conical bucket and is surrounded by a plurality of mounting frames equidistantly connected thereto, and a spray head is installed at the end of each mounting frame.

[0016] By adopting the above technical solution, when the parts are placed inside the conical bucket and tumbled, the staff adds several small balls into the conical bucket, and multiple nozzles spray paint on the surface of the parts at the same time. Compared with the traditional single nozzle painting, the painting efficiency and spray range are greatly improved, and the situation of incomplete painting is avoided. In addition, when the paint is placed or used for a long time, pigment precipitation and solvent volatilization may occur, resulting in local concentration changes. The small balls rolling in the conical bucket will continuously stir the paint, ensuring that the composition of the paint sprayed each time is uniform, so that the color and coating effect of the surface of the sprayed parts are uniform.

[0017] The present invention is further configured as follows: the adjustment component includes a support rod rotatably connected to the inner center of the conical bucket and a fixed plate installed on the outer side wall of the support rod, the outer side wall of the support rod and located on both sides of the fixed plate are provided with rotatable gear bars, the outer side wall of each gear bar is slidably connected with a sleeve, the first mesh plate is installed on the outer side wall of one of the sleeves, the sorting mechanism is installed on the outer side wall of the other sleeve, and the first mesh plate is located in the counterclockwise direction of the sorting mechanism.

[0018] The present invention is further configured as follows: a bidirectional cylinder is horizontally installed at the bottom of the fixed plate, the two piston rods of the bidirectional cylinder are both installed with limit clamps, ring bodies are installed inside the opposite sides of the two sleeves, the two limit clamps are arranged corresponding to the two ring bodies, and the limit clamp sleeves are arranged on the outer wall position of the corresponding ring body.

[0019] The present invention is further configured as follows: a mounting hole is provided on the side wall of the fixing plate, an adjusting motor is vertically installed on the top of the fixing plate, the output end of the adjusting motor extends into the mounting hole and is connected to a driving bevel gear, the opposite sides of the two gear bars are connected to driven bevel gears, the support rod passes through the center of the side wall of the driven bevel gear, and the driven bevel gear is meshed with the driving bevel gear.

[0020] By adopting the above technical solution, when the support rod rotates, it drives the gear bar to rotate synchronously. Since the teeth on the inner wall of the sleeve are meshed with the teeth on the outer wall of the gear bar, when the gear bar rotates, it can drive the sleeve to rotate synchronously. When the sleeve rotates, it drives the first mesh plate and the sorting mechanism to rotate synchronously, so that the first mesh plate and the sorting mechanism cooperate to move to a high position where the component is lifted. When the component rolls, it is blocked by the first mesh plate and the sorting mechanism. After the component reaches the height of the first mesh plate and the sorting mechanism, it is directly blocked from rolling, thereby avoiding the situation where some components are lifted too high and affect the rolling speed.

[0021] In summary, the present application includes at least one of the following beneficial technical effects:

[0022] (1) By setting an adjustment component, when the sleeve rotates, the first mesh plate and the sorting mechanism are driven to rotate synchronously, so that the first mesh plate and the sorting mechanism cooperate to move to a high position where the component is lifted. When the component rolls, it is blocked by the first mesh plate and the sorting mechanism. After the component reaches the height of the first mesh plate and the sorting mechanism, it is directly blocked from rolling, thereby avoiding the situation where some components are lifted too high and affect the rolling speed.

[0023] (2) By setting a bidirectional cylinder and a limit clamp, the bidirectional cylinder pushes the limit clamp to move, and the limit clamp pushes the corresponding ring body and sleeve to move synchronously, thereby adjusting the distance between the two sleeves. One sleeve drives the first mesh plate to move, and the other sleeve drives the second mesh plate to move. The first mesh plate and the second mesh plate are pressed against each other, thereby squeezing the large paint blocks between the first mesh plate and the second mesh plate, causing the large paint blocks to be divided into small paint blocks by the grid of the second mesh plate, and then fall into the inside of the conical bucket for collection.

[0024] (3) By setting the first mesh plate and the second mesh plate to be both wavy in shape, the raised position of the first mesh plate corresponds to the sunken position of the second mesh plate. When the large paint block is squeezed by the first mesh plate and the second mesh plate, the shape settings of the two can prevent the large paint block from being squeezed into a sheet and unable to fall.

[0025] (4) By setting the connecting block and the top block, after the large paint block is squeezed, part of the paint block will still stick to the grid of the first mesh plate. When the first mesh plate and the second mesh plate are fitted together, since the connecting block and the top block in the second mesh plate correspond to the middle of the grid of the first mesh plate, the connecting block and the top block cooperate to push out the flaky paint blocks accumulated in the grid of the first mesh plate, and push the paint blocks back to the component position. The paint blocks are squeezed again and fall between the first mesh plate and the second mesh plate, and are processed through the above operation to avoid the paint blocks getting stuck and unable to be processed.

[0048] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application may be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0049] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0050] See also Figure 1-14 , the present invention provides the following technical solutions:

[0051] Example 1, see Figure 1 and Figure 2 A surface painting treatment device for a power tool housing component includes a main body component 1, the main body component 1 includes a frame 11, a swing component 2 is installed inside the frame 11, a conical bin 3 is installed on the top of the swing component 2, and a door body 4 is installed at the end of the conical bin 3. The swing component 2 is used to drive the conical bin 3 to swing. When the conical bin 3 swings to an upward tilted state, the staff opens the door body 4 and pours the parts to be sprayed into the conical bin 3 for storage, which is convenient for subsequent painting operations. When the conical bin 3 tilts downward, the parts inside the conical bin 3 can be discharged, which is convenient for the staff to collect the parts.

[0052] See also Figure 1-Figure 3 The main component 1 also includes a collecting box 12 installed at the bottom of the front surface of the frame 11. A filter screen 13 is horizontally installed on the top of the collecting box 12. The filter screen 13 is located directly below the conical bin 3. The components poured out from the conical bin 3 fall onto the surface of the filter screen 13, and the impurities inside the conical bin 3 are poured out simultaneously. The filter screen 13 filters the impurities, that is, the impurities fall into the interior of the collecting box 12 through the filter screen 13, and the components are accumulated on the surface of the filter screen 13, which is convenient for the staff to collect the components.

[0053] See also Figure 1-Figure 3 A heater 14 is installed on one side of the frame 11. The air outlet of the heater 14 is connected to an exhaust pipe 15. The end of the exhaust pipe 15 away from the heater 14 is connected to the side wall of the conical bin 3. The connection between the exhaust pipe 15 and the conical bin 3 is arranged on the same side as the door body 4. The heater 14 is equipped with a fan. When the fan rotates, it will suck the cold air in the room into the heater 14. When the cold air sucked into the heater 14 passes through the heating element, the cold air absorbs heat and becomes hot air. Then, the hot air is blown out of the heater 14 through the air outlet under the push of the fan.

[0054] When the parts inside the conical bin 3 are prepared for painting, the hot air generated by the heater 14 is first discharged to the inside of the conical bin 3 through the exhaust pipe 15, thereby preheating the inside of the conical bin 3. When the appropriate temperature is reached, the staff will spray the parts. During the spraying process, the hot air can quickly dry the paint sprayed on the surface of the parts, thereby improving the spraying efficiency.

[0055] See also Figure 4 The specific structure of the swing assembly 2 is as follows:

[0056] The swing assembly 2 includes a support platform 21 installed inside the frame 11 and located on the side wall of the collection box 12, and a servo motor 22 installed on the top of the support platform 21. The output end of the servo motor 22 is connected to a swing rod, and a U-shaped frame 23 is installed on the outer wall of the swing rod. A connecting rod 25 is installed on the top of the U-shaped frame 23. The connecting rod 25 extends from one end of the U-shaped frame 23 to the end position of the conical bin 3. The servo motor 22 is used to drive the swing rod to rotate, thereby driving the U-shaped frame 23 and the connecting rod 25 to swing. The connecting rod 25 is used to provide auxiliary support for the conical bin 3. When the U-shaped frame 23 and the connecting rod 25 swing, the conical bin 3 swings synchronously, thereby being able to adjust the angle of the conical bin 3, that is, during the loading and painting process of the conical bin 3, the conical bin 3 is in a tilted upward state, and when the conical bin 3 is unloading, the conical bin 3 is in a tilted downward state.

[0057] See also Figure 4 In this embodiment, a lifting cylinder 24 is hingedly installed on the top of the supporting platform 21, and the piston rod end of the lifting cylinder 24 is hingedly connected to the bottom of the U-shaped frame 23, and the hinge point is located at one end of the U-shaped frame 23 away from the servo motor 22. The lifting cylinder 24 is used to assist in supporting the U-shaped frame 23, that is, when the U-shaped frame 23 and the connecting rod 25 support and swing the conical bin 3, the lifting cylinder 24 is used to assist in supporting and lifting the U-shaped frame 23 to prevent the U-shaped frame 23 from being deformed by the gravity of the conical bin 3.

[0058] See also Figure 4-Figure 6 A rotating assembly 5 is installed inside the conical bin 3. The rotating assembly 5 is used to roll the components inside the conical bin 3 to facilitate the subsequent painting of the components. The specific structure of the rotating assembly 5 is as follows:

[0059] See also Figure 4-Figure 6 In this embodiment, the rotating assembly 5 includes a rotating motor 51 installed at the bottom of the U-shaped frame 23 and a rotating shaft 52 connected to the output end of the rotating motor 51. One end of the rotating shaft 52 passes through the bottom center point of the conical bin 3 and extends to the inside of the conical bin 3. The end of the rotating shaft 52 away from the rotating motor 51 is connected to a conical bucket 53. The conical bucket 53 is located inside the conical bin 3. The rotating motor 51 is used to drive the rotating shaft 52 and the conical bucket 53 to rotate. When the component is placed inside the conical bin 3, the component is first received by the conical bucket 53. When the conical bucket 53 rotates, the component is lifted following the rotation of the conical bucket 53. When the component is lifted to a certain height, the component slides down due to gravity, that is, the component that rolls to the highest position slides down to the middle of the pile, and so on.

[0060] See also Figure 1 and Fig.14A spraying assembly 6 is installed at the end of the conical bin 3. When the component rolls inside the conical bin 3, the spraying assembly 6 sprays the surface of the rolling component. The specific structure of the spraying assembly 6 is as follows:

[0061] See also Fig.14 In this embodiment, the spraying assembly 6 includes a bracket 61 installed at the end of the conical bin 3, one end of the bracket 61 extends to the interior of the conical bucket 53 and is equidistantly connected with a plurality of mounting frames 62, and a nozzle 63 is installed at the end of each mounting frame 62. When the component is placed in the conical bucket 53 and tumbled, the staff adds a number of small balls into the conical bucket 53, and the plurality of nozzles 63 simultaneously spray paint on the surface of the component. Compared with the traditional single nozzle painting, the painting efficiency and the range of the painting are greatly improved, and the situation of incomplete painting is avoided. In addition, when the paint is placed for a long time or used, the pigment may precipitate, the solvent may volatilize, and cause local concentration changes. The rolling of the small balls in the conical bucket 53 will continuously stir the paint, ensuring that the paint composition sprayed each time is uniform, so that the color and coating effect of the surface of the sprayed component are uniform.

[0062] Embodiment 2: The existing device can only spray one type of component. If multiple types of components are added, the tumbling heights of the components will be inconsistent due to the different volumes and shapes of the components during tumbling. Some components will tumble too fast, resulting in a long spraying time. In addition, adding small balls to multiple components will also cause inconsistent tumbling heights, resulting in uneven spraying.

[0063] For this purpose, see Figure 1-Figure 5 A driving motor 7 is installed at the end of the conical bin 3, and the driving motor 7 is located at the circular part of the end of the conical bin 3. An adjusting component 8 is installed at the center of the conical bucket 53. The output end of the driving motor 7 is connected to the adjusting component 8. A processing component 9 is installed on the outer wall of the adjusting component 8. The driving motor 7 is used to drive the adjusting component 8 to roll, so that the processing component 9 installed on the outer wall of the adjusting component 8 is stirred inside the conical bucket 53, and the processing component 9 can intercept the rolling parts to ensure that the lifting height of the parts is the same each time, so as to avoid the different rolling speeds of the parts due to different lifting heights affecting the painting effect.

[0064] See also Figure 5-Figure 10 , the specific structure of the regulating component 8 is as follows:

[0065] In this embodiment, the adjustment component 8 includes a support rod 81 rotatably connected to the inner center of the conical bucket 53 and a fixed plate 84 installed on the outer wall of the support rod 81. The output end of the drive motor 7 is connected to the end of the support rod 81. The drive motor 7 is used to drive the support rod 81 and the fixed plate 84 to rotate synchronously inside the conical bucket 53. The outer wall of the support rod 81 and both sides of the fixed plate 84 are rotated with gear bars 82. The outer wall of each gear bar 82 is slidably connected with a sleeve 83. When the support rod 81 rotates, it drives the gear bar 82 to rotate synchronously. Since the teeth on the inner wall of the sleeve 83 are meshed with the teeth on the outer wall of the gear bar 82, when the gear bar 82 rotates, it can drive the sleeve 83 to rotate synchronously.

[0066] See also Figure 4 The processing component 9 includes a first mesh plate 91 and a sorting mechanism 92. The first mesh plate 91 is installed on the outer wall of one of the sleeves 83, and the sorting mechanism 92 is installed on the outer wall of the other sleeve 83. The first mesh plate 91 is located in the counterclockwise direction of the sorting mechanism 92. When the sleeve 83 rotates, it drives the first mesh plate 91 and the sorting mechanism 92 to rotate synchronously, so that the first mesh plate 91 and the sorting mechanism 92 cooperate to move to a high position where the component is lifted. When the component rolls, it is blocked by the first mesh plate 91 and the sorting mechanism 92. After the component reaches the height of the first mesh plate 91 and the sorting mechanism 92, it is directly blocked from rolling, thereby avoiding the situation where some components are lifted too high and affect the rolling speed.

[0067] In the third embodiment, during the tumbling painting process of the parts, some paint will accumulate on the surface of the parts. After a period of time, paint blocks will appear. The paint blocks will be knocked off by the added balls, and the fallen paint blocks will remain in the material pile. In this state, the paint blocks will be repeatedly flipped over with the parts, and the paint blocks will be re-sprayed with paint, and their surfaces will re-adhere to the parts, resulting in uneven spraying.

[0068] For this purpose, see Figure 7-10 A mounting hole is provided on the side wall of the fixing plate 84, an adjusting motor 85 is vertically installed on the top of the fixing plate 84, the output end of the adjusting motor 85 extends into the mounting hole and is connected to a driving bevel gear 86, the opposite sides of the two gear bars 82 are connected to driven bevel gears 87, the support rod 81 passes through the center of the side wall of the driven bevel gear 87, and the driven bevel gear 87 is meshed with the driving bevel gear 86.

[0069] The adjusting motor 85 is used to drive the active bevel gear 86 to rotate, and the active bevel gear 86 drives the two driven bevel gears 87 to rotate. The rotation directions of the two driven bevel gears 87 are opposite. The two driven bevel gears 87 respectively drive the corresponding gear bars 82 and the sleeve 83 to rotate synchronously. The sleeve 83 drives the first mesh plate 91 and the sorting mechanism 92 to approach or move away from each other. The position where the two are close to each other is on the counterclockwise side of the adjusting motor 85. When the two are close to each other, the support rod 81 rotates to drive the adjusting assembly 8 to rotate as a whole, so that the first mesh plate 91 and the sorting mechanism 92 cooperate to limit the lifting height of the component.

[0070] When the two move away from each other, the paint block in the component can be processed, that is, the first mesh plate 91 and the sorting mechanism 92 are displaced as a whole to surround and lift the component, and then the first mesh plate 91 and the sorting mechanism 92 are separated, and the component is lifted to a certain height by the first mesh plate 91, and the sorting mechanism 92 is separated from the first mesh plate 91, and the paint block falls downward through the first mesh plate 91, and then the paint block is processed by the sorting mechanism 92. The specific structure of the sorting mechanism 92 is as follows:

[0071] See also Figure 11-13 The sorting mechanism 92 includes a second mesh plate 921 installed on the outer wall of the adjusting component 8, a groove is provided in the middle of the side of the second mesh plate 921 close to the adjusting component 8, and a third mesh plate 922 is hinged inside the groove, and the third mesh plate 922 is connected to the inner wall of the groove through a rotating column, and the outer wall of the rotating column is sleeved with a torsion spring 924, and the two ends of the torsion spring 924 are respectively connected to the inner wall of the groove and the side wall of the third mesh plate 922, and micro-limit push rods 923 are installed on both sides of the second mesh plate 921, and multiple grids of the second mesh plate 921 are connected with connecting blocks 925, and a top block 926 is installed on the side of the connecting block 925 close to the first mesh plate 91, and the second mesh plate 921 of the sorting mechanism 92 is used as the main body of the processing, that is, when the first mesh plate 91 lifts the component again, the second mesh plate 921 is separated from the first mesh plate 91, and because the connecting block 925 is arranged in the grid of the second mesh plate 921, the grid size of the second mesh plate 921 is smaller than the grid size of the first mesh plate 91.

[0072] In order to prevent the second mesh plate 921 from colliding with the adjusting motor 85 during the displacement process, the third mesh plate 922 is set. When the second mesh plate 921 moves to the position of the adjusting motor 85, the third mesh plate 922 is squeezed and swings and twists the torsion spring 924. After the second mesh plate 921 passes the adjusting motor 85, the torsion spring 924 is driven by the force to drive the third mesh plate 922 to return to its original position. In order to prevent the third mesh plate 922 from affecting the use of the second mesh plate 921, the micro limit push rod 923 is extended to limit and block the second mesh plate 921.

[0073] Since the sizes of the paint blocks are inconsistent, small paint blocks can directly pass through the first mesh plate 91 and the second mesh plate 921 and fall directly into the interior of the conical bucket 53 for collection, while large paint blocks pass through the first mesh plate 91 and are carried and collected by the second mesh plate 921 .

[0074] See also Figure 7-10 A two-way cylinder 88 is horizontally installed at the bottom of the fixed plate 84. The two piston rods of the two-way cylinder 88 are both installed with limit clamps 89. Ring bodies 891 are installed inside the opposite sides of the two sleeves 83. The two limit clamps 89 are arranged corresponding to the two ring bodies 891. The limit clamps 89 are sleeved on the outer wall position of the corresponding ring bodies 891. Since the teeth on the outer wall of the sleeve 83 are meshed with the teeth on the outer wall of the gear bar 82, the sleeve 83 can not only rotate synchronously with the gear bar 82, but also the sleeve 83 can slide on the outer wall of the gear bar 82. The sliding drive of the sleeve 83 is driven by the two-way cylinder 88 is applied, that is, the two-way cylinder 88 pushes the limit clamp 89 to move, and the limit clamp 89 pushes the corresponding ring body 891 and the sleeve 83 to move synchronously, thereby adjusting the distance between the two sleeves 83, one sleeve 83 drives the first mesh plate 91 to move, and the other sleeve 83 drives the second mesh plate 921 to move, and the first mesh plate 91 and the second mesh plate 921 are pressed against each other, thereby squeezing the large paint blocks between the first mesh plate 91 and the second mesh plate 921, causing the large paint blocks to be divided into small paint blocks by the grid of the second mesh plate 921, and then fall into the interior of the conical bucket 53 for collection.

[0075] See also Fig.11 and Fig.12 , and the first mesh plate 91 and the second mesh plate 921 are both wavy in shape, the raised position of the first mesh plate 91 corresponds to the sunken position of the second mesh plate 921, when the large paint block is squeezed by the first mesh plate 91 and the second mesh plate 921, the shape settings of the two can prevent the large paint block from being squeezed into a sheet and unable to fall.

[0076] After the large paint block is squeezed, part of the paint block will still stick to the grid of the first mesh plate 91. Therefore, when the first mesh plate 91 and the second mesh plate 921 are fitted together, since the connecting block 925 and the top block 926 in the second mesh plate 921 correspond to the middle of the grid of the first mesh plate 91, the connecting block 925 and the top block 926 cooperate to push out the flaky paint blocks accumulated in the grid of the first mesh plate 91, and the paint blocks are pushed back to the position of the component. The paint blocks are squeezed again and fall between the first mesh plate 91 and the second mesh plate 921, and are processed through the above-mentioned operation. After the paint blocks are discharged through the door body 4 position of the conical bin 3, the component continues to be sprayed with paint.

[0077] Obviously, the above-described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.
