Description

Technical Field

[0001] The utility model relates to the technical field of screening equipment, and more specifically to a water drill grading and screening equipment. Background Art

[0002] Rhinestones, also known as crystal glass diamonds or rhinestones, are widely used in clothing, shoes, jewelry and other decorative items.

[0003] During the processing, diamonds need to be classified according to their size. The screening equipment in the prior art screens through multiple screens, and there is no blocking structure on the screens, which causes the diamonds to enter the next screen before being completely screened out by the previous screen, and further manual cleaning is required. Furthermore, a storage frame is placed on the ground below the screen, and the diamonds fall directly from the mesh into the storage frame, which can easily cause the diamonds to break. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of the utility model is to provide a grading and screening device which can fully screen water diamonds.

[0005] In order to solve the above problems, the utility model adopts the following technical solutions: A water diamond grading and screening device, comprising:

[0008] An obstruction member, installed on the top of the screen and at least one, obstructs the rolling of the diamonds;

[0009] The material blocking mechanism comprises a baffle installed at the inclined end of the screen and a driving member driving the baffle to block and discharge the material;

[0010] The material receiving structure comprises a material guide frame installed at one end of the frame close to the screen and located below the screen, and a material discharge port is provided on the material guide frame;

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] A water diamond grading and screening device comprises: a frame 1; a plurality of screens 2 are arranged in a stepped manner along the inclined direction, and a plurality of the screens 2 are respectively provided with mesh holes 21 with gradually increasing apertures along the inclined direction; an obstruction member 3, at least one of which is installed on the top of the screen 2 to obstruct the rolling of the water diamond; a material blocking mechanism 4, comprising a baffle 41 installed at the inclined end of the screen 2 and a driving member 44 driving the baffle 41 to block and discharge the material; a material receiving structure, comprising a material guide frame 51 installed at one end of the frame 1 close to the screen 2 and located below the screen 2, and a material discharge port 52 is provided on the material guide frame 51; and a vibration assembly 6, which drives the screen 2 to vibrate. It can be understood that the frame 1 is a component that supports the entire device, such as Figure 1 As shown, it adopts a structure of four columns and a crossbeam installed on the top, of course, other supporting structures can also be used. The obstruction member 3 can be a long strip structure, or a raised structure installed on the top of the screen 2. The driving member 44 can drive the baffle 41 to flip over to block and discharge materials, and can also stretch up and down to achieve the blocking and discharge of water rhinestones. The guide frame 51 collects and guides the screened water rhinestones, and finally guides them out from the discharge port 52. The vibration component 6 can adopt a motor-driven eccentric block vibration structure, a vibration motor direct drive structure, pneumatic or hydraulic vibration, etc. In this way, when screening water rhinestones, pour the water rhinestones onto the highest screen 2, and the vibration component 6 drives the screen 2 to vibrate and then screen and transmit along the inclined direction, and fall onto the next screen 2. The screened water rhinestones fall onto the guide frame 51 and are guided out from the discharge port 52. When it is found that there are still some rhinestones on the screen 2 that have not been completely screened out, the driving member 44 drives the baffle 41 to close the inclined end of the screen 2, so that the rhinestones remain on the screen 2 and continue to vibrate and screen. After the screening is complete, the driving member 44 drives the baffle 41 to stop closing the inclined end of the screen 2, so that the rhinestones fall into the next screen 2. In this way, the rhinestones can be completely screened without manual subsequent re-selection.

[0028] Optionally, in some embodiments, the rack 1 is provided with a plurality of screens 2, and the height of the rack 1 along the inclination direction of the screen 2 decreases step by step. Here, one rack 1 is installed corresponding to one screen 2, and each rack 1 is independent, which is convenient for adjusting the position of the screen 2. Since the screens 2 are arranged in a stepped manner, the rack 1 is in a stepped shape, and the height decreases step by step. Of course, the rack 1 can also be integrated, and the top of the rack 1 can be set in a stepped shape.

[0029] Optionally, in some embodiments, the screen 2 is provided with a panel 7 on both sides, and the vibration assembly 6 includes a spring 61 and a vibrator 62 installed between the panel 7 and the frame 1. It can be understood that the two panels 7 can play a guiding and limiting role in the vibration transmission of the water drill. At the same time, the panel 7 is connected to the frame 1 by the spring 61, thereby also playing a role in fixing the screen 2. The vibrator 62 can be a vibrator 62 such as a vibration motor. Further, the bottom of one end of the panel 7 along the inclination direction of the screen 2 is provided with two spaced positioning parts 71; the material blocking mechanism 4 also includes a rotating shaft 42 rotatably installed between the two fixed parts, and a connecting part 43 installed on the rotating shaft 42 and extending along the inclination direction of the screen 2; the baffle 41 is installed on the connecting part 43, and the driving member 44 uses a motor to drive the rotating shaft 42 to rotate and then drive the baffle 41 to flip to achieve material blocking and material discharge. Here, the connection part 43 is set to a concave arc structure, and can also be set to a bent structure, so that the baffle 41 can fit and close the inclined end of the screen 2. The motor drives the rotating shaft 42 to rotate, and then drives the baffle 41 to swing through the connection part 43 to achieve the blocking and discharge of the water rhinestones.

[0030] Optionally, in some implementations, the axial direction of the blocking member 3 is perpendicular to the tilt direction of the screen 2, so that the blocking member 3 is also perpendicular to the transmission direction of the water drill, thereby better blocking the vibration transmission of the water drill. Further, the top of the blocking member 3 is set to be arc-shaped, so that the water drill can vibrate through the blocking member 3 without being completely blocked.

[0031] Optionally, in some embodiments, the material guide frame 51 is tilted, and the discharge port 52 is located at the lowest point of the tilt of the material guide frame 51. It can be understood that if the cross section of the material guide frame 51 is square and has four corners, the discharge port 52 is located at one of the four corners, and the corner is located at the lowest point of the tilt, and the other corners are higher than the corner. In this way, when the rhinestones fall on the material guide frame 51, they will roll towards the discharge port 52 due to gravity. Furthermore, a material guide trough 53 is installed on the discharge port 52, and a material receiving frame can be placed at the end of the material guide trough 53, and the material guide trough 53 guides the rhinestones from the discharge port 52 to the material receiving frame.

[0032] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
