Description

Technical Field

[0001] The utility model relates to the technical field of coating manufacturing, in particular to a novel vibrating screen. Background Art

[0002] Powder coating is a solid powdered synthetic resin coating composed of solid resin, pigment, filler and additives. Its dispersion medium is air instead of solvent and water, so it has the characteristics of no solvent pollution, 100% film formation and low energy consumption. Powder has a certain degree of adhesion and will clump at high temperature. In order to facilitate the storage of powder coating and make it have better spraying effect when used, the powder coating is sieved through a vibrating screen to make the powder coating looser.

[0003] When powder coating is screened by a vibrating screen, due to the certain viscosity of the powder coating, the powder coating will stick to the sieve holes of the sieve when passing through the sieve, which can easily lead to clogging of the sieve. The staff needs to clean the sieve frequently, resulting in a waste of time and greatly reducing the working efficiency of the vibrating screen. Therefore, a vibrating screen that can avoid clogging of the sieve has become one of the problems to be solved urgently in this field. Utility Model Content

Detailed implementation manners

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Refer to Figures 1-6 , a new type of vibrating screen provided in this embodiment includes a base 1, a screening frame 3 is arranged on the base 1 through a vibration spring 2, a vibration motor 4 is arranged at the bottom of the screening frame 3, a sieve mesh 6 is detachably installed inside the screening frame 3 through an installation component 5, a connection component 7 is arranged at a position below the sieve mesh 6 inside the screening frame 3, an elastic ball 9 suspended below the sieve mesh 6 is arranged on the connection component 7 through a connection rope 8, and when the vibrating screen vibrates, the elastic ball 9 impacts on the sieve mesh 6.

[0027] In the present utility model, the vibrating screen is placed through the base 1. The vibrating motor 4 at the bottom of the screening frame 3 is started, so that the screening frame 3 vibrates above the base 1 through the vibration springs 2. The powder coating is fed onto the vibrating screen under the action of the conveyor. The screen mesh 6 in the screening frame 3 screens the powder coating. A resilient ball 9 is suspended by a connecting rope 8 on the connecting assembly 7 below the screen mesh 6. During the screening process, the vibrating motor 4 cooperates with the vibration springs 2 to vibrate the screening frame 3, and the resilient ball 9 inside the screening frame 3 vibrates accordingly. Since the resilient ball 9 is suspended by the connecting rope 8, it will jump irregularly during vibration, so that the resilient ball 9 impacts on the screen mesh 6, and then a local impact is generated on the screen mesh 6, vibrating the powder adhered in the screen holes of the screen mesh 6 and preventing the screen mesh 6 from being blocked;

[0028] When screening different types of powder coatings, select the screen mesh 6 with the corresponding mesh number according to the coating type. The screen mesh 6 is quickly disassembled through the installation assembly 5, and the selected screen mesh 6 can be quickly installed by using the installation assembly 5 again.

[0029] Specifically, referring to Figures 2-4 As shown in the figure, the connecting assembly 7 includes a pair of positioning plates 71 fixed on the inner wall of the screening frame 3. Positioning holes 72 are formed in the positioning plates 71. A connecting rod 73 is arranged between the positioning plates 71. Both ends of the connecting rod 73 are sleeved with inserting rods 75 adapted to the positioning holes 72 through connecting grooves 74, and a return spring 76 is arranged between the inserting rod 75 and the inner wall of the connecting groove 74. A hanging member 79 cooperating with the connecting rope 8 is arranged on the connecting rod 73. The connecting rope 8 of the resilient ball 9 is tied to the hanging member 79 of the connecting rod 73. When replacing or cleaning the resilient ball 9, compress the inserting rods 75 at both ends of the connecting rod 73, so that the inserting rods 75 squeeze the return spring 76 and retract into the connecting grooves 74, and the inserting rods 75 are disengaged from the positioning holes 72 of the positioning plates 71, and then the connecting rod 73 is lifted upward, so as to take out the resilient ball 9 from the screening frame 3 for replacement or cleaning.

[0030] Wherein, a sliding groove 77 communicating with the connecting groove 74 is formed on the lower side surface of the connecting rod 73, and a pulling plate 78 penetrating through the sliding groove 77 and extending to a position below the connecting rod 73 is arranged on the inserting rod 75. When compressing the inserting rod 75 to make it contract inside the connecting groove 74, the fingers of the operator can rest on the pulling plate 78, and the pulling plate 78 protruding outside can be used to more conveniently and labor-savingly pull the inserting rod 75 to move, so as to shorten the disassembly time of the connecting assembly 7.

[0031] Specifically, referring to Figure 2 and Figure 3, the number of elastic balls 9 is several, and several elastic balls 9 are evenly distributed along the diameter path below the screen 6 through the connecting ropes 8. Through several elastic balls 9, different areas of the screen 6 can be impacted during vibration, causing more local impacts on the screen 6, so as to effectively vibrate the powder adhered to the screen 6 and avoid the blockage of the screen 6 caused by powder adhesion.

[0032] It should be noted that the elastic ball 9 is of a hollow structure, and the connecting rope 8 is made of an elastic rope material. The hollow elastic ball 9 has a smaller mass, which can avoid damage to the screen 6 caused by excessive impact force when the elastic ball 9 jumps irregularly. The connecting rope 8 made of elastic rope material can ensure that the vibrating screen can drive the elastic ball 9 to jump during vibration, so as to form an impact force on the screen 6.

[0033] Specifically, referring to Figure 2 and Figure 5 , the installation component 5 includes a positioning ring 51 integrally provided with the screening frame 3. A support rod 52 is provided on the positioning ring 51, and a nut 54 is provided at the upper end of the support rod 52 through a threaded end 53.

[0034] A connecting hole 61 matching the threaded end 53 is opened at the edge position of the screen 6. The diameter of the support rod 52 is larger than the diameter of the connecting hole 61, and the nut 54 abuts against the upper side of the screen 6 through the threaded end 53. When screening different types of powder coatings, select a screen 6 with the corresponding mesh number according to the powder type. At this time, unscrew the nut 54 on the threaded end 53 at the top of the support rod 52, and then remove and replace the screen 6. Since the diameter of the connecting hole 61 on the screen 6 is smaller than the diameter of the support rod 52, when the nut 54 is removed, the screen 6 will still rest on the support rod 52 under the action of gravity, and there is no need to worry about the screen 6 falling off, which is convenient for replacing the screen 6.

[0035] Specifically, referring to Figure 1 and Figure 6 , a foot component 10 is provided at the bottom of the base 1. The foot component 10 includes an installation screw 101. A rubber pad 102 is provided at the lower end of the installation screw 101, and a backing plate 103 is provided at a position near the upper end of the installation screw 101. A damping pad 104 is sleeved on the outside of the installation screw 101 between the rubber pad 102 and the backing plate 103, and a locking nut 105 is provided at the upper end of the installation screw 101. After the installation screw 101 penetrates the bottom of the base 1, the backing plate 103 abuts against the lower side of the base 1, and then it is locked with the locking nut 105. When the vibrating screen is in use, the rubber pad 102 provides friction to make the vibrating screen stable, and the damping pad 104 can perform a certain degree of shock absorption and buffering to improve the safety of the vibrating screen during use.

[0036] It should be noted that the number of the vibration springs 2 is several and they are evenly arranged along the circumferential direction of the top of the base 1. Connecting ends are provided at both ends of the vibration springs 2. The vibration springs 2 are connected to the base 1 and the screening box 3 through the connecting ends. The several vibration springs 2 distributed in a circumferential manner make the vibrating screen more evenly stressed during operation, avoiding equipment damage or a decline in screening effect caused by uneven stress.

[0037] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
