Description

Technical Field

[0001] The utility model relates to the field of powder coating equipment, and particularly discloses a powder coating screening machine. Background Art

[0002] In food processing, to enhance the food's taste, a coating device is often used to coat the food's surface with a layer of powder. For example, coating fried chicken cutlets with powder can impart a distinct flavor while preserving the original flavor. Existing coating methods involve placing the food on a coating table or drum, then discarding the remaining material after coating, resulting in significant waste.

[0003] In order to overcome the above technical defects, Chinese patent CN217664626U discloses a vibrating powder coating and screening machine. The vibrating powder coating and screening machine of this technical solution has a simple and compact structural design, occupies a small area, and can quickly separate and recycle dry powder and wet powder. However, the powder coating and screening machine still has the technical problem that waste residue cannot be directly separated during the vibration process, and its screening efficiency is low. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the utility model proposes a powder coating screening machine, which can directly separate waste residue during the vibration process, and the efficiency of separating dry powder and waste residue is high.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] Compared with the prior art, the powder coating screening machine provided by the utility model sets the vertical height of the first end and the second end at a different level, so that the first screen is tilted in the horizontal direction. When the vibration component drives the screening mechanism to vibrate, it drives the first screen to vibrate. Therefore, during the vibration process, the dry powder in the powder material after coating moves toward the second end, and finally falls into the material receiving container and can be used again. The large particles of waste residue after coating gradually move toward the first end during the vibration process, and finally the waste residue directly goes out from the residue discharge channel, and the separation efficiency of dry powder and waste residue is high.

[0008] Preferably, the screening container includes a second enclosure and a first enclosure, the first enclosure is arranged on the front and rear sides of the first screen and is connected to the first screen, and a slag discharge channel is provided between the first end and the second enclosure.

[0009] Preferably, a plurality of strip-shaped protrusions are longitudinally arranged on the first screen.

[0010] Preferably, the screening container further comprises a second screen, wherein the second screen is connected to the second end and forms an obtuse angle with the first screen.

[0011] Preferably, the second enclosure plate and the first enclosure plate are arranged to be inclined in the vertical direction.

[0012] Preferably, the vibration assembly includes a motor box, a vibration frame, and a vibration motor arranged in the motor box, and the motor box is fixed on an inclined plate of the vibration frame.

[0013] Preferably, the powder coating screening machine also includes a recovery component, which includes a waste residue recovery container and a material guide member, the material guide plate of the material guide member is arranged above the waste residue recovery container and below the end of the first end, and the material guide plate is arranged to be inclined downward.

[0014] Compared with the prior art, the present invention has the following advantages

[0015] (1) The powder coating screening machine provided by the present invention is configured such that the first screen is tilted in the horizontal direction by setting the vertical heights of the first end and the second end different. When the vibration component drives the screening mechanism to vibrate, the first screen is driven to vibrate. Thus, during the vibration process, the dry powder in the powder material after coating moves toward the second end and finally falls into the receiving container and can be used again. The large particles of waste residue after coating gradually move toward the first end during the vibration process, and finally the waste residue goes out from the residue discharge channel, completing the separation of dry powder and waste residue, which is beneficial to the recovery of the dry powder after coating and reduces costs.

[0016] (2) The powder coating and screening machine provided by the present invention greatly improves the efficiency of powder screening after coating by tilting the second screen in the screening container. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] See also Figures 1 to 5 The present invention discloses a powder coating screening machine, including a frame 1. The bottom of the frame 1 in this embodiment is provided with a pulley assembly for easy movement. A material receiving container 2 is installed in the frame 1, and the material receiving container 2 is slidably connected to the upper frame 11 of the frame 1. A screening mechanism 3 and a vibration component 4 are provided above the material receiving container 2. The vibration component 4 is connected to the screening mechanism 3, thereby driving the screening mechanism 3 to vibrate. The screening mechanism 3 includes a first screen 31 and a screening container. The screening container is surrounded by the first screen 31. The first screen 31 includes a first end 311 and a second end 312. The vertical height of the first end 311 is greater than the vertical height of the second end 312. The screening container includes a second enclosure 33 and a first enclosure 32. The first enclosure 32 is provided on the front and rear sides of the first screen 31 (with Figure 2 For reference), and connected to the first screen 31 , a slag discharge channel 34 is provided between the first end 311 and the second enclosure plate 33 .

[0034] In this embodiment, by setting the vertical heights of the first end 311 and the second end 312 to be different, the first screen 31 is tilted in the horizontal direction. When the vibration component 4 drives the screening mechanism 3 to vibrate, it drives the first screen 31 to vibrate, so that during the vibration process, the dry powder in the powder after coating moves toward the second end 312, and finally falls into the material receiving container 2 and can be used again. During the vibration process, the large particles of waste residue after coating gradually move toward the first end 311, and finally the waste residue goes out directly from the residue discharge channel 34, quickly completing the separation of dry powder and waste residue.

[0035] Specifically, a plurality of strip-shaped protrusions 3111 are longitudinally provided on the first screen 31. In this embodiment, the strip-shaped protrusions 3111 are evenly distributed on the first screen 31, which is conducive to the waste residue moving toward the first end 311 faster and improving the residue removal efficiency.

[0036] Specifically, the screening container also includes a second screen 35, which is connected to the second end 312 and forms an obtuse angle with the first screen 31, so that when the powdered material after being coated enters the screening mechanism 3, part of the powdered material after being coated can vibrate on the first screen 31, so that the dry powder can pass through the second screen 35 and fall into the receiving container 2, thereby improving the efficiency of powder screening.

[0037] Specifically, the second enclosure 33 and the first enclosure 32 are tilted in the vertical direction. Therefore, the screening container in this embodiment is bucket-shaped, which is more conducive to the powder after being coated to slide smoothly onto the first screen 31, thereby improving the efficiency of powder screening.

[0038] Specifically, the vibration assembly 4 includes a motor box 41, a vibration frame 43, a vibration motor (not shown in the figure) arranged in the motor box 41, and a spring 42 arranged on the upper frame 11 of the frame 1. One end of the spring 42 is connected to the first connecting block 111 of the upper frame 11 of the frame 1, and the other end of the spring 42 is connected to the connecting plate 433 at the bottom of the vibration frame 43. The motor box 41 is fixed on the inclined plate 431 of the vibration frame 43, so that when the vibration motor in the motor box 41 drives the vibration frame 43 to vibrate, the vibration noise is small.

[0039] Specifically, the vibration frame 43 is mounted on the periphery of the screening container, the inclined plate 431 is adjacent to the second screen 35, the upper opening of the vibration frame 43 extends horizontally outward with a first side plate 432, and the upper opening of the screening container extends horizontally outward with a second side plate 351, the second side plate 351 is arranged on the first side plate 432, and is detachably connected through the fixing component 5, so as to facilitate the separation of the screening container and the first screen 31 from the vibration frame 43, and take it down for easy cleaning.

[0040] Specifically, the fixing assembly 5 includes a fixing frame 51 and a plurality of fixing members 52. The second side plate 351 is arranged between the first side plate 432 and the fixing frame 51. The fixing member 52 includes a first fixing member 521 and a fixing connecting member 522. There are four fixing members in this embodiment. The first fixing member 521 and the fixing connecting member 522 can be connected or separated. The first fixing member 521 is fixed on the second connecting block 434 of the first side plate 432. The fixing connecting member 522 is arranged on the fixing frame 51. When the first fixing member 521 and the fixing connecting member 522 are separated, the fixing frame 51 can be taken down, and then the screening container and the first screen 31 can be taken out for cleaning.

[0041] Specifically, the fixing assembly 5 also includes a positioning column 53. In this embodiment, there are two positioning columns 53. The positioning columns 53 are inserted into the holes on the fixing frame 51, the second side plate 351, and the first side plate 432 in sequence, thereby fixing the relative positions of the fixing frame 51, the screening container, and the vibration frame 43 to avoid displacement during the vibration process.

[0042] Specifically, the powder coating screening machine also includes a recovery component 6, which includes a waste residue recovery container 61 and a material guide member 62. The material guide plate 621 of the material guide member 62 is arranged on the waste residue recovery container 61 and below the end of the first end 311. The material guide plate 621 is arranged to be tilted downward to facilitate the waste residue vibrated out of the first end 311 to be introduced into the waste residue recovery container 61.

[0043] Specifically, handles 511 are provided on the left and right sides of the fixing frame 51 to facilitate taking the fixing frame 51 .

[0044] Specifically, the upper frame 11 is also provided with a slide rail 112, and the outer edge of the material receiving container 2 is slidably connected to the slide rail 112. When installed in this way, the outer edge of the material receiving container 2 can be pushed in from the outside along the slide rail 112, and taking and placing are very convenient and easy to operate.

[0045] During operation, the powdered material is poured into the screening mechanism 3, and then the vibration motor is started. High-frequency vibration is generated by the motor and transmitted to the vibration frame 43. The vibration frame 43 can move up and down under the elastic action of the spring 42, thereby driving the screening mechanism 3 to vibrate. The dry powder in the powdered material moves toward the second end 312 after being coated, and finally falls into the material receiving container 2 and can be used again. The large particles of waste residue after being coated gradually move toward the first end 311 during the vibration process, and finally the waste residue goes out directly from the residue discharge channel 34, passes through the guide plate 621, and enters the waste residue recovery container 61, quickly completing the separation of dry powder and waste residue. After testing, the powdered screening machine provided in this embodiment can complete the screening of 4 kilograms of powdered material within 30 seconds, and the powder screening efficiency is high.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
