Technical Field
[0001] This utility model relates to the field of spraying technology, specifically to a spraying device for manufacturing speaker housings. Background Technology
[0002] The components of a spray coating equipment for manufacturing speaker housings:
[0003] Paint storage tanks: Made of stainless steel, their capacity depends on the production scale. Small speaker enclosures typically use tanks with a capacity of 20-50 liters, while large-scale production may use tanks with capacities of several hundred liters. They have excellent sealing properties to prevent paint evaporation and impurities from entering.
[0004] Paint delivery pumps: These are mostly plunger pumps or gear pumps. Plunger pumps can provide higher pressure and are suitable for delivering high-viscosity paints, with a pressure range of 0.5-2MPa. Gear pumps, on the other hand, operate more smoothly and have a relatively stable flow rate, typically ranging from 1 to 10 liters per minute. The appropriate pump can be selected based on the required spraying speed.
[0005] Paint filter: Installed in the delivery pipeline, the filter screen pore size is usually 50-200 microns. It is used to filter particulate impurities in the paint, ensuring that the sprayed paint is fine and uniform, and avoiding impurities from affecting the surface quality of the speaker housing.
[0006] Working principle:
[0007] Paint preparation and delivery: Pour the prepared paint into the paint storage tank, start the paint delivery pump, and under the pressure of the pump, the paint is filtered through the paint filter and delivered to the spray gun through the delivery pipeline.
[0008] Spray formation: Compressed air is output from an air compressor and enters the spray gun through an air pipe. Inside the spray gun, the compressed air and paint are mixed in a specific channel. The paint is atomized into fine particles under the impact of the high-speed compressed air, forming a spray.
[0009] Spraying process: The operator holds the spray gun, aims the spray at the surface of the speaker housing, and pulls the trigger. The atomized paint is evenly sprayed onto the housing. During the spraying process, the spray pattern, paint flow rate, and spray gun movement speed can be adjusted according to the shape and size of the housing and the spraying requirements to ensure uniform paint coverage and achieve the desired appearance. Simultaneously, the control system monitors and adjusts parameters such as pressure and flow rate in real time during the spraying process to ensure the stability of the spraying quality.
[0010] Existing spraying equipment for speaker housing manufacturing has the following drawbacks: residual paint in the workbench will contaminate the new speaker housing. During the spraying process, the new speaker housing is placed on the workbench with residual paint, and the residual paint will stick to the surface of the workpiece. If it is a different color paint, it will cause the surface of the workpiece to be mixed with color and have defects. Utility Model Content
[0011] The purpose of this invention is to provide a spraying device for manufacturing speaker housings, in order to solve the problem mentioned above where residual paint on the workbench will stick to the surface of the workpiece, and different colors of paint will cause the surface of the workpiece to be mixed with color and have defects.
[0012] To achieve the above objectives, the present invention provides the following technical solution: a spraying device for manufacturing speaker housings, comprising a base and a spraying machine, a worktable is provided on the top of the base, a groove for placing speaker housings is provided on the worktable, the spraying machine is positioned above the worktable, and a stirring rod is detachably installed inside the spraying machine;
[0013] The base is equipped with a spraying component for spraying the speaker housing;
[0014] The spraying machine is equipped with an adjustment component for disassembling and assembling the mixing rod;
[0015] The spraying assembly includes a clamping plate slidably connected to one end of a groove. A first cylinder is provided at the end of the clamping plate and is mounted on a worktable. A fixing plate is fixedly provided at the other end of the groove. Limiting blocks are symmetrically arranged at both ends of the groove. A first limiting sleeve is fixedly arranged in the groove and is located above the limiting blocks. A cavity is opened in the first limiting sleeve, and a first limiting rod is inserted into the cavity. A first spring is sleeved on the first limiting rod, and a limiting groove is opened on the first limiting rod. A paint plate is inserted into the limiting block and is inserted into the limiting groove. Sliding parts with the same structure are symmetrically arranged at both ends of the spraying machine.
[0016] Preferably, the adjusting component includes a paint container installed inside the sprayer. A motor is detachably installed on the top of the paint container, and a rotating shaft is rotatably connected to the bottom of the motor. Sleeves for inserting a stirring rod are symmetrically arranged on both sides of the rotating shaft. A second limiting sleeve is provided on the sleeve. A limiting ring is provided at the top of the second limiting sleeve. A through hole is opened in the limiting ring. A limiting post is inserted into the through hole. A second limiting rod is threaded to the bottom of the limiting post. A second spring is sleeved on the limiting post. The second spring is located between the limiting ring and the second limiting rod. A sealing ring is sleeved on the limiting post and is located in the through hole. A limiting hole for inserting the limiting post is opened on the stirring rod.
[0017] Preferably, a gasket is bonded between the clamping plate and the fixing plate, and the gasket covers the surfaces of the clamping plate and the fixing plate.
[0018] Preferably, a liquid-holding tank is provided above the workbench, and the liquid-holding tank is located at the bottom of the spraying machine.
[0019] Preferably, a first groove is provided in the limiting block, and a slider is slidably connected in the first groove. The slider is fixedly mounted on the side wall of the clamping plate.
[0020] Preferably, a connecting rod is detachably installed on each of the two adjacent stirring rods, and a scraper is inserted into the connecting rod.
[0021] Compared with the prior art, the beneficial effects of this utility model are:
[0022] 1. In this utility model, by placing the speaker housing in a groove, the first cylinder is driven, which drives the clamping plate. The clamping plate slides within the groove, and together with the fixing plate, clamps the speaker housing. Adhesive gaskets protect the speaker housing, preventing damage when the clamping plate impacts it. The second cylinder is then driven, which drives a moving plate. The moving plate slides horizontally within a second groove in the fixing seat, and the moving plate drives a spraying machine. The spraying machine sprays paint onto the speaker housing. Excess paint at the bottom of the spray gun is sprayed onto a paint plate, preventing paint from adhering to the limiting block. The adhesive paint plate prevents paint residue from remaining on the top of the limiting block, thus preventing accumulated paint. The paint drips into the groove, affecting the spraying of the next set of speaker housings. When the paint plate needs to be replaced, the first limiting rod is pushed. The first limiting rod moves horizontally within the cavity, and the cavity limits the end of the first limiting rod to prevent it from falling out of the cavity. The first spring deforms under force, so that the limiting groove leaves the paint plate surface, making it easier to replace the paint plate. After the paint plate is replaced manually, the reaction force generated by the first spring pushes the first limiting rod in the opposite direction. The limiting groove on the first limiting rod limits the paint plate. The spraying assembly solves the problem of paint residue on the worktable. Residual paint will stick to the surface of the speaker housing. Different colors of paint will cause the surface of the speaker housing to be mixed and have defects.
[0023] 2. In this utility model, by rotating the motor, the motor drives the rotating shaft, which in turn drives the stirring rod to stir the paint in the paint container. When it is necessary to clean the inner wall of the paint container, the limiting post is pulled, which drives the second limiting rod. The second limiting rod compresses the second spring, causing the second spring to deform. The second limiting rod then enters the second limiting sleeve, pulling the stirring rod, which moves within the sleeve. The limiting post is then released, and it is inserted into the limiting hole, thus limiting the stirring rod. The connecting rod is then installed on the stirring rod, and the scraper is inserted onto the connecting rod. The scraper cleans the inside of the paint container. Attached Figure Description

Detailed Implementation
[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] Example 1
[0032] Please see Figure 1 - Figure 5 The illustration shows a spraying device for manufacturing speaker housings, including a base 1 and a spraying machine 6. A workbench 2 is provided on the top of the base 1, and a groove 3 for placing speaker housings is provided on the workbench 2. The spraying machine 6 is located above the workbench 2, and a stirring rod 9 is detachably installed inside the spraying machine 6.
[0033] The base 1 is equipped with a spraying component 7 for spraying the speaker housing;
[0034] The spraying machine 6 is equipped with an adjustment component 8 for disassembling and assembling the stirring rod 9;
[0035] The spraying assembly 7 includes a clamping plate 702 slidably connected to one end of the groove 3. A first cylinder 701 is provided at the end of the clamping plate 702 and is mounted on the worktable 2. A fixing plate 711 is fixedly provided at the other end of the groove 3. Limiting blocks 704 are symmetrically provided at both ends of the groove 3. A first limiting sleeve 712 is fixedly provided in the groove 3 and is located above the limiting block 704. A cavity 713 is provided in the first limiting sleeve 712. A first limiting rod 714 is inserted into the cavity 713. A first spring 715 is sleeved on the first limiting rod 714. A limiting groove 716 is provided on the first limiting rod 714. A paint plate 705 is inserted into the limiting block 704 and is inserted into the limiting groove 716. Sliding parts with the same structure are symmetrically provided at both ends of the spraying machine 6.
[0036] In this design, during use, the speaker housing is placed in the groove 3. The first cylinder 701 (a piston-type cylinder, where the piston is the main moving part and reciprocates linearly within the cylinder, is the most common type of cylinder) is driven. The first cylinder 701 drives the clamping plate 702, which slides within the groove 3. The clamping plate 702, in conjunction with the fixing plate 711, clamps the speaker housing. The second cylinder 708 is then driven, which in turn drives the moving plate 4. The moving plate 4 slides horizontally within the second groove 710 of the fixing seat 709. The moving plate 4 drives the spray gun 6, which sprays the speaker housing. During spraying, excess paint at the bottom of the spray gun is sprayed onto the paint plate 705 (a specially designed absorbent plate, made of specially treated fiberboard or composite board with tiny pores on its surface), preventing paint from adhering to the limiting block 704. The paint plate 705 prevents paint residue from remaining on the top of the limiting block 704. Accumulated paint flowing down into the groove 3 would affect the painting of the next set of speaker housings. When the paint plate 705 needs to be replaced, the first limiting rod 714 is pushed. The first limiting rod 714 moves horizontally within the cavity 713, and the cavity 713 limits the end of the first limiting rod 714, preventing it from falling out of the cavity 713. The first spring 715 deforms under force, thus limiting the groove 71. 6. The paint plate 705 is removed from the surface of the paint plate 705, making it easy to replace the paint plate 705. After the paint plate 705 is replaced manually, the reaction force generated by the first spring 715 pushes the first limit rod 714 in the opposite direction. The limit groove 716 opened by the first limit rod 714 limits the paint plate 705. The spraying component 7 solves the problem of paint residue on the workbench 2. Residual paint will stick to the surface of the speaker shell. Different colors of paint will cause the surface of the speaker shell to be mixed with color and have defects.
[0037] Furthermore, the adjusting component 8 includes a paint container 801 disposed within the sprayer 6. A motor 802 is detachably mounted on the top of the paint container 801. A rotating shaft 803 is rotatably connected to the bottom of the motor 802. Sleeves 804 for inserting the stirring rod 9 are symmetrically arranged on both sides of the rotating shaft 803. A second limiting sleeve 805 is provided on the sleeve 804. A limiting ring 810 is provided at the top of the second limiting sleeve 805. A through hole 807 is opened in the limiting ring 810. A limiting post 811 is inserted into the through hole 807. A second limiting rod 813 is threaded to the bottom of the limiting post 811. A second spring 812 is sleeved on the limiting post 811. The second spring 812 is located between the limiting ring 810 and the second limiting rod 813. A sealing ring 814 is sleeved on the limiting post 811 and is located within the through hole 807. A limiting hole 806 for inserting the limiting post 811 is opened on the stirring rod 9.
[0038] Specifically, during use, the motor 802 is rotated, which drives the rotating shaft 803. The rotating shaft 803 drives the stirring rod 9 to stir the paint in the paint container 801. When it is necessary to clean the inner wall of the paint container 801, the limiting post 811 is pulled. The limiting post 811 drives the second limiting rod 813. The second limiting rod 813 compresses the second spring 812, causing the second spring 812 to deform. The second limiting rod 813 enters the limiting sleeve 805, pulling the stirring rod 9. The stirring rod 9 moves within the sleeve 804. The limiting post 811 is released, and it is inserted into the limiting hole 806, thereby limiting the stirring rod 9.
[0039] A gasket 703 is bonded between the clamping plate 702 and the fixing plate 711, and the gasket 703 covers the surface of the clamping plate 702 and the fixing plate 711; the bonded gasket 703 protects the speaker housing and prevents the clamping plate 702 from damaging the speaker housing when it impacts the speaker housing.
[0040] A liquid collection tank 5 is provided above the workbench 2, and the liquid collection tank 5 is located at the bottom of the spraying machine 6. The liquid collection tank 5 is provided to collect the residual paint from the spray gun at the bottom of the spraying machine 6, so as to prevent the residual paint from dripping onto the workbench 2 and affecting the spraying of the speaker shell.
[0041] The limiting block 704 has a first sliding groove 706, and a slider 707 is slidably connected in the first sliding groove 706. The slider 707 is fixedly installed on the side wall of the clamping plate 702. The slider 707 slides horizontally in the first sliding groove 706. The first sliding groove 706 limits the clamping plate 702 through the slider 707, and limits the clamping plate 702 while preventing the angle of the clamping plate 702 from changing during movement.
[0042] Two adjacent stirring rods 9 are detachably mounted with connecting rods 808, and scrapers 809 are inserted into the connecting rods 808; the connecting rods 808 are installed on the stirring rods 9 and the scrapers 809 are inserted into the connecting rods 808, and the scrapers 809 clean the inside of the paint container 801.
