Description

Technical Field

[0001] This utility model relates to the field of screening device technology, and in particular to a high-efficiency screening device for plastic powder. Background Technology

[0002] Powder coating is a dry coating composed of resin, curing agent, pigments, fillers and additives. It has significant advantages: it has no solvent evaporation, is environmentally friendly, and can reduce pollution to the environment; after curing, the coating is hard, wear-resistant and corrosion-resistant, which can extend the service life of the workpiece; and a thick coating can be obtained with one spraying, which has high construction efficiency, can be recycled, reduces production costs, and has broad application prospects.

[0003] In the production of plastic powder, sieving devices play a crucial role, effectively removing coarse particles, lumps, and impurities mixed in with the plastic powder. Sieving ensures that the plastic powder has a uniform particle size, allowing for more precise control of product quality in subsequent processing steps such as blending. It also prevents unstable coating performance caused by particle size differences, making it an indispensable key piece of equipment in the plastic powder production process. Currently, circular vibrating screens are commonly used for filtering plastic powder. However, existing circular vibrating screens typically use a vibrating screen to sieve the plastic powder above, which often gets clogged, leading to reduced sieving efficiency. Based on this, this utility model is proposed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a high-efficiency sieving device for plastic powder that can overcome or at least partially solve the above problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-efficiency sieving device for plastic powder includes a support base and a housing connected to the support base. The housing is provided with a sieving component and a guide plate. Multiple counterweight balls roll inside the sieving component. When the sieving component shakes and sieves, the counterweight balls roll inside the sieving component and impact the sieving component to generate vibration.

[0007] Preferably, the screening assembly includes a screening mesh, a support mesh, and a vortex baffle. The screening mesh and the support mesh are fixedly connected to the vortex baffle, and the screening mesh and the support mesh are designed in an inverted conical shape.

[0008] Furthermore, the vortex baffle is provided with multiple guide ramps and protrusions. The counterweight ball rolls in the track formed by the vortex baffle and the support net. When the counterweight ball passes the guide ramp, the counterweight ball is lifted up and falls back onto the support net, generating vibration. When the counterweight ball passes the protrusion, the counterweight ball impacts the vortex baffle, generating vibration.

[0009] Preferably, the screening component is connected to a discharge pipe in the middle, and the bottom of the discharge pipe is connected to a conveying pipe and a waste pipe.

[0010] Furthermore, the housing is provided with a protective shell, and an elevator is provided inside the protective shell. The elevator is provided with multiple feeding hoppers, and the conveying pipe is connected to the protective shell.

[0011] Furthermore, a connecting pipe is connected to the protective shell, and the connecting pipe is connected to the shell. The counterweight ball is conveyed to the connecting pipe via the feeding hopper.

[0012] Preferably, the guide plate is arranged in a perfect conical shape, and the housing is connected to a discharge pipe.

[0013] Preferably, a hopper is connected to the housing, a support spring is connected between the support base and the housing, and a vibration motor is provided at the bottom of the housing.

[0014] Compared with the prior art, this utility model provides a high-efficiency sieving device for plastic powder, which has the following beneficial effects:

[0015] 1. This high-efficiency plastic powder screening device, by setting up a screening screen, a vortex baffle and a discharge pipe, enables the plastic powder to move and be screened along the trajectory guided by the vortex baffle, thereby increasing the screening movement path of the plastic powder and improving the screening quality. At the same time, it can also guide the larger plastic powder particles that are screened out to gather together and be discharged.

[0016] 2. This high-efficiency sieving device for plastic powder, by setting up a support net, guide inclined blocks and protrusions, can transmit the vibration generated by the impact of the counterweight ball on the support net and the vortex baffle to the sieving net, thereby shaking the plastic powder out of the sieving net and promoting the sieving speed.

[0017] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model improves the screening quality of plastic powder, reduces the probability of plastic powder clogging the screening holes, speeds up the screening process, and promotes the screening speed.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] Example 1: Refer to Figures 1-5 A high-efficiency sieving device for plastic powder includes a support base 1 and a housing 2 connected to the support base 1. The housing 2 contains a sieving component 4 and a guide plate 45. Multiple counterweight balls 44 roll within the sieving component 4. When the sieving component 4 shakes and sieves, the counterweight balls 44 roll within the sieving component 4 and impact the sieving component 4, generating vibration. The sieving component 4 includes a sieving screen 41, a support screen 42, and a vortex baffle 43. The sieving screen 41 and the support screen 42 are fixedly connected. The screen 41 and the support net 42 are fixedly connected to the vortex baffle 43. The screen 41 and the support net 42 are designed in an inverted conical shape. The vortex baffle 43 is provided with multiple guide blocks 431 and protrusions 432. The counterweight ball 44 rolls in the track formed by the vortex baffle 43 and the support net 42. When the counterweight ball 44 passes the guide block 431, the counterweight ball 44 is lifted up and falls back onto the support net 42 to generate vibration. When the counterweight ball 44 passes the protrusion 432, the counterweight ball 44 impacts the vortex baffle 43 to generate vibration.

[0027] In this utility model, the external driving method and connection method of the device are the same as those of the circular vibrating screen. The difference from the existing device is that by setting a screening screen 41 and a vortex baffle 43 inside the housing 2, the plastic powder can be allowed to move along the trajectory guided by the vortex baffle 43 when screening the plastic powder. This increases the screening time and guides the screened plastic powder to gather together and be discharged.

[0028] By setting a support net 42 above the screening net 41, the counterweight ball 44 can be supported to roll while the plastic powder falls onto the screening net 41. When the screening component 4 starts to shake and screen, the counterweight ball 44 will roll along the guide of the vortex baffle 43. When the counterweight ball 44 rolls to the guide inclined block 431, it will move up away from the support net 42 under the guidance of the guide inclined block 431 and fall back onto the support net 42. Thus, the falling back will generate vibration on the support net 42 and transmit it to the screening net 41. This will cause some plastic powder stuck in the screen 41 to fall out of the mesh due to vibration. When the counterweight ball 44 passes the protrusion 432, it will be lifted up and hit the vortex baffle 43 to generate vibration. The vibration of the vortex baffle 43 can also transmit the vibration to the screening net 41 and shake the plastic powder out of the mesh.

[0029] Example 2: Refer to Figures 1-5 Similar to Example 1, but further: the screening component 4 is connected to the middle of the discharge pipe 5, the bottom of the discharge pipe 5 is connected to the conveying pipe 51 and the waste pipe 22, the housing 2 is provided with a protective shell 32, the protective shell 32 is provided with an elevator 3, the elevator 3 is provided with multiple feeding hoppers 31, the conveying pipe 51 is connected to the protective shell 32, the protective shell 32 is connected to the connecting pipe 33, the connecting pipe 33 is connected to the housing 2, the counterweight ball 44 is conveyed to the connecting pipe 33 via the feeding hopper 31, the guide plate 45 is set in a perfect conical shape, the housing 2 is connected to the discharge pipe 23, the housing 2 is connected to the discharge hopper 21, the support base 1 is connected to the housing 2 with a support spring 11, and the bottom of the housing 2 is provided with a vibration motor 24.

[0030] In this invention, the discharge pipe 5 is connected to the middle of the screening screen 41, and the middle of the support mesh 42 has a circular hole, so that the counterweight ball 44 and the plastic powder remaining on the screening screen 41 are guided by the vortex baffle 43 into the discharge pipe 5 and fall onto the conveying pipe 51. The bottom of the conveying pipe 51 is also a mesh structure, so that the plastic powder can fall into the waste pipe 22 through the bottom of the conveying pipe 51 and be conveyed out, while the counterweight ball 44 will fall into the feeding hopper 31. Figure 3As shown, the bottom plate of the feeding hopper 31 is designed as an inclined surface to guide the counterweight ball 44 to roll to one side of the conveying pipe 51, so that the counterweight ball 44 can automatically roll into the conveying pipe 51 when it is brought to one side of the conveying pipe 51 by the feeding hopper 31 and fall back onto the screening component 4 under the guidance of the conveying pipe 51. The elevator 3 is an existing device, and its operation mode and connection with the feeding hopper 31 are not described in detail.

[0031] After being sieved, the plastic powder falls onto the guide plate 45 and is guided to the discharge pipe 23 by the shaking.

[0032] The feeding hopper 21 is positioned above the starting point of the vortex baffle 43;

[0033] When using the equipment, the user only needs to pour the plastic powder into the screening component 4 through the hopper 21 and place the receiving device at the discharge pipe 23 and waste pipe 22. Then, the vibrating motor 24 can be started to drive the housing 2 to shake for screening. At the same time, the elevator 3 can be started to send the counterweight ball 44 into the screening component 4 to generate a knocking vibration to assist in screening. All operations can be completed.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
