Description

Technical Field

[0001] This utility model relates to the field of powder recovery technology in the spraying industry, and in particular to the powder scraping trolley in the powder spraying booth. Background Technology

[0002] A powder coating booth is a piece of equipment used for surface coating, primarily for spraying powder coatings. It's a common coating process in modern manufacturing. The powder that falls off during the spraying process needs to be recycled and reused. If the powder from the powder coating booth is directly released into the environment, it will pollute the air and water, impacting the ecological environment. Recycling this powder can effectively reduce environmental pollution and protect the ecological environment. Currently, the most widely used methods in the market are manual powder scraping and large cyclone powder recycling.

[0003] The existing technical solutions mentioned above have the following drawbacks: the current manual powder recycling rate is unstable, and it is inconvenient to carry out recycling operations during the production process. Generally, the operation is carried out after the machine is stopped, which affects production. Moreover, the powder will clump together when it is exposed to moisture, and it needs to be screened again. Affected by the weather and the accumulation time, the amount of powder that can be reused after screening is unstable, and the waste powder rate reaches 25% to 50%.

[0004] The large cyclone powder recovery method uses the suction force generated by the fan to drive the dust into the small cyclone for powder separation. The separated powder is sent back to the powder supply center for secondary use. Due to the influence of the fan suction, some ultrafine powder is too light and will be carried to the secondary filter dust collector, where it will be intercepted and become waste powder. Over a long period of recycling, the ultrafine powder will be slowly sucked into the secondary filter dust collector, leaving only coarse powder in the powder, which will cause the spraying effect to gradually deteriorate and the waste powder rate to reach 15% to 30%. Utility Model Content

[0005] The purpose of this invention is to provide a powder scraping trolley for a powder spraying booth.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

One end of the outer side of the positioning bead is engaged with the slot. The brush strip is engaged inside the mounting base and is interference-fitted with the mounting base.

[0014] By adopting the above technical solution, the scraper has a limiting structure, making it more convenient to use.

[0015] Furthermore, two of each of the first and second magnets are provided, and the magnetic directions of the first and second magnets are the same. Two of each of the front and rear push rods are provided symmetrically.

[0016] By adopting the above technical solution, and through two magnetic structures with the same vertical direction, the movement of the trolley can be controlled by magnetic force.

[0017] In summary, the beneficial technical effects of this utility model are as follows:

[0018] The device employs a trolley assembly, a tractor, magnets, a powder collection trough, and front and rear push rods. A trolley with magnets is added inside the powder collection trough within the base plate, and a tractor with another set of identical magnets is added to the lower end of the base plate. This allows the trolley to move, and powder is scraped off using scrapers and brush strips. The front and rear push rods control the scraper to flip, and positioning beads provide limit positions. The overall structure achieves automatic powder scraping, resulting in a convenient user experience. Attached Figure Description

Detailed Implementation

[0024] The present invention will be further described in detail below with reference to the accompanying drawings.

[0025] Reference Figure 1-4The powder coating booth scraping trolley includes a powder coating booth base plate 1. A powder collection trough 2 is provided inside the base plate 1. A trolley assembly 3 is installed inside the powder collection trough 2. The trolley assembly 3 includes a frame 31, wheels 32, guide wheels 33, a connecting shaft 34, positioning beads 35, a scraper 36, a slot 37, a mounting base 38, and a brush strip 39. Wheels 32 are installed at the bottom of the frame 31, and guide wheels 33 are installed on the outer side of the frame 31. The connecting shaft 34 and positioning beads 35 are fixedly connected inside the frame 31. A scraper 36 is installed on the outer side of the connecting shaft 34, and a slot 37 is provided on the outer side of the scraper 36. A mounting base 38 is fixedly connected to one end of the outer side of the scraper 36. A brush strip 39 is engaged inside the mounting base 38. A dust cover 4 is fixedly connected to the outer side of the frame 31, and a first magnet 5 is fixedly connected to the outer side of the frame 31 inside the dust cover 4. The bottom of the powder coating booth base plate 1 is equipped with... A tractor 6 is provided, with a second magnet 7 fixedly connected to the outside of the tractor 6. A powder drop port 8 is opened inside the powder spraying chamber floor 1. A front push rod 101 is fixedly connected to one end of the powder spraying chamber floor 1, and a rear push rod 102 is fixedly connected to the other end of the powder spraying chamber floor 1. A powder collection trolley is added inside the powder collection trough 2. The scraper 36 can be controlled at any time through the structure of the flip-up scraper 36 and the positioning bead 35, which facilitates the limitation and fixation. The powder collection trough 2 is cleaned by the brush strip 39 at the bottom. The scraped powder falls out from the powder drop port 8 and is collected. The cycle is repeated until it is clean. The addition of the tractor 6 and two sets of magnets with the same vertical direction can control the movement of the trolley inside the powder collection trough 2 by magnetic force to achieve automatic cleaning. At the same time, the push rods at the front and rear positions can flip the scraper 36 to different positions. When scraping powder, the scraper 36 is downward and when resetting, the scraper 36 is upward, which is easy to adjust.

[0026] like Figure 1-4 As shown, there are four walking wheels 32, two sets of guide wheels 33 are symmetrically arranged, and two guide wheels 33 are arranged in each set. The guide wheels 33 are in contact with the inner side of the powder collection trough 2. There are two connecting shafts 34, slots 37 and positioning beads 35 respectively. The scraper 36 is rotatably connected to the connecting shaft 34. One end of the outer side of the positioning bead 35 is engaged with the slot 37. The brush strip 39 is engaged inside the mounting base 38 and is interference-fitted with the mounting base 38. There are two first magnets 5 and two second magnets 7 respectively. The magnetic direction of the first magnets 5 and the second magnets 7 is the same up and down. There are two front push rods 101 and two rear push rods 102 respectively.

[0027] The implementation principle of this embodiment is as follows: The powder scraping trolley is placed above the powder collection trough 2, the scraper 36 is in a downward-tilted state, and the powder scraping trolley is not scraping powder. Under the traction of the magnetic traction vehicle 6, the powder scraping trolley moves forward, and the brush strip 39 scrapes the powder in the powder collection trough 2 to the powder drop outlet 8. The powder falls into the powder bucket for recycling. The powder scraping trolley continues to move forward to the front push rod 101, and the front push rod 101 pushes the scraper 36 to an upward-tilted state. At the same time, the positioning bead 35 engages in the slot 37, locking the position of the scraper 36. At this point, the brush strip 39 leaves the surface of the powder collection trough 2, and the powder scraping trolley moves backward under magnetic traction. During the backward movement, the brush strip 39 leaves the surface of the powder collection trough 2, and the powder scraping trolley is in a non-powder scraping state. The powder scraping trolley moves backward to the rear push rod 102, and the rear push rod 102 pushes the scraper 36 to the downward flipped state. The brush strip 39 is attached to the surface of the powder collection trough 2. At this time, the powder scraping trolley completes one powder scraping process. The above operation is repeated continuously until the powder that has fallen in the powder spraying chamber is scraped back into the powder drop port 8. The cleaning work is then completed.

[0028] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
