[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0030] Example 1, referring to Figures 1 to 8 This is the first embodiment of the present invention, which provides a vibrating screen for feeding, comprising:
[0031] The feeding assembly 1 includes a side plate 11, a base plate 12 disposed at the bottom of the side plate 11, and an anti-stick structure disposed on the surface of the base plate 12; and,
[0032] The screening assembly 4 includes a receiving tray 41, an inclined guide plate 45 disposed at the bottom of the receiving tray 41, a vibrating motor 42 disposed on the side of the inclined guide plate 45, and a screen plate 46 disposed on the surface of the receiving tray 41.
[0033] The anti-stick structure prevents materials from sticking to the surface of the base plate 12 by increasing the vibration amplitude of the base plate 12 or shortening the material movement path, thereby accelerating the material feeding speed.
[0034] The anti-stick structure includes a positioning post 13, an elastic plate 14, a middle plate 15, and a pressing plate 16. The two ends of the middle plate 15 are fixed with elastic plates 14, and the other end of the elastic plate 14 is fixedly connected to the bottom plate 12. The elastic plate 14 and the middle plate 15 are located in the middle of the bottom plate 12.
[0035] The upper end of the side plate 11 is fixedly connected to the inclined guide plate 45, and the positioning column 13 is fixed on the surface of the support frame. When the side plate 11 vibrates, the positioning column 13 remains stable.
[0036] A positioning post 13 is provided at the bottom of the base plate 12, and an extrusion plate 16 is fixed on the surface of the positioning post 13. The surface of the extrusion plate 16 is in contact with the bottom of the middle plate 15.
[0037] The extrusion plate 16 is fixed to the surface of the positioning column 13, thus keeping it stationary. When the middle plate 15 vibrates, it moves up and down, impacting the extrusion plate 16, thereby increasing the movement range of the middle plate 15 and accelerating the material feeding speed.
[0038] The screening assembly 4 also includes a positioning frame 43 fixed on the surface of the receiving tray 41, and an adjusting baffle 44 is slidably connected to the surface of the positioning frame 43.
[0039] The bottom of the positioning frame 43 is fixed to the surface of the receiving tray 41. The adjusting baffle 44 slides on the positioning frame 43 to change the space at the bottom of the adjusting baffle 44, thereby controlling the material feeding speed and increasing the efficiency of material screening.
[0040] A rubber spring pad 3 is fixed to the side of the receiving tray 41, and a support frame 2 is fixed to the bottom of the rubber spring pad 3. The two ends of the support frame 2 are at different heights.
[0041] The rubber spring pad 3 is placed between the receiving tray 41 and the support frame 2, which can alleviate the impact of the vibration of the receiving tray 41 on the support frame 2 and ensure that the position of the support frame 2 remains stable.
[0042] The tilt angle of the receiving tray 41 is equal to the tilt angle of the inner surface of the inclined guide plate 45.
[0043] The inclined inner surface of the guide plate 45 is inclined to ensure the normal downward movement of the material. The inclination of the receiving tray 41 also allows the material to move downward normally, reducing the accumulation of material.
[0044] The bottom of the inclined guide plate 45 is provided with a slot, and the slot is located at the lowest point of the inclined guide plate 45.
[0045] The slot allows the material to easily detach from the inclined guide plate 45. The slot is set at the highest point of the feeding assembly 1, and the material moves downward along the feeding assembly 1.
[0046] Usage process: The material is poured onto the surface of the receiving tray 41. The vibration motor 42 is started, and the vibration motor 42 drives the receiving tray 41 to vibrate. The material moves downward along the receiving tray 41. The powder in the material passes through the sieve plate 46 and falls onto the surface of the bottom plate 12 along the inclined guide plate 45. Since the upper end of the side plate 11 is fixedly connected to the inclined guide plate 45, the inclined guide plate 45 drives the bottom plate 12 and the middle plate 15 to vibrate. Since the positioning column 13 is fixed on the surface of the support frame 2, the extrusion plate 16 remains stable. Since the middle plate 15 moves up and down when vibrating, the middle plate 15 collides with the extrusion plate 16, and the elastic plate 14 deforms, increasing the vibration amplitude of the middle plate 15 and ensuring that the material on the surface of the bottom plate 12 and the middle plate 15 falls quickly.
[0047] Example 2, refer to Figures 1 to 8 This is the second embodiment of the present invention, which provides a vibrating screen for feeding, comprising:
[0048] The feeding assembly 1 includes a side plate 11, a base plate 12 disposed at the bottom of the side plate 11, and an anti-stick structure disposed on the surface of the base plate 12; and,
[0049] The screening assembly 4 includes a receiving tray 41, an inclined guide plate 45 disposed at the bottom of the receiving tray 41, a vibrating motor 42 disposed on the side of the inclined guide plate 45, and a screen plate 46 disposed on the surface of the receiving tray 41.
[0050] The anti-stick structure prevents materials from sticking to the surface of the base plate 12 by increasing the vibration amplitude of the base plate 12 or shortening the material movement path, thereby accelerating the material feeding speed.
[0051] The anti-stick structure includes a feeding plate 17 and a feeding port 18. The feeding port 18 is located on the surface of the base plate 12, and the feeding plate 17 is located at the edge of the feeding port 18.
[0052] The upper end of the side plate 11 is fixed to the bottom of the inclined guide plate 45. The side plate 11 and the bottom plate 12 vibrate with the inclined guide plate 45. The length of the moving path of the bottom plate 12 is reduced by the discharge port 18, thereby avoiding the adhesion of materials.
[0053] Usage process: When the material falls onto the surface of the base plate 12, the material's movement path becomes shorter because the base plate 12 has a discharge port 18. It is difficult for the material to stick to the surface of the base plate 12, and it enters the discharge port 18 along the base plate 12 and falls out of the discharge plate 17 along the discharge port 18.
[0054] Example 3, referring to Figures 1 to 8 This is the third embodiment of the present invention, which provides a vibrating screen for feeding, comprising:
[0055] The feeding assembly 1 includes a side plate 11, a base plate 12 disposed at the bottom of the side plate 11, and an anti-stick structure disposed on the surface of the base plate 12; and,
[0056] The screening assembly 4 includes a receiving tray 41, an inclined guide plate 45 disposed at the bottom of the receiving tray 41, a vibrating motor 42 disposed on the side of the inclined guide plate 45, and a screen plate 46 disposed on the surface of the receiving tray 41.
[0057] The anti-stick structure prevents materials from sticking to the surface of the base plate 12 by increasing the vibration amplitude of the base plate 12 or shortening the material movement path, thereby accelerating the material feeding speed.
[0058] The anti-sticking structure includes a telescopic plate 19, a vibrating plate 20, a lower plate 21, a connecting plate 22, a positioning plate 23, and an upper plate 24. The upper plate 24 is provided above the bottom plate 12, and the lower plate 21 is provided below the bottom plate 12. The telescopic plate 19 is fixed in the middle of the lower plate 21, the upper plate 24, and the bottom plate 12. The vibrating plate 20 is fixed at the upper end of the lower plate 21, the upper plate 24, and the bottom plate 12.
[0059] The upper end of the vibrating plate 20 is fixed to the bottom of the inclined guide plate 45, while the side plate 11 is fixed to the surface of the positioning column 13 by the positioning plate 23. Then the lower plate 21, the upper plate 24 and the bottom plate 12 vibrate, while the side plate 11 remains stable. They are connected by the connecting plate 22, which will deform to adapt to the change in the position of both ends.
[0060] A connecting plate 22 is fixed to the outer side of the lower plate 21, the upper plate 24 and the bottom plate 12. A side plate 11 is fixed to the other end of the connecting plate 22. A positioning plate 23 is fixed to the surface of the side plate 11. A positioning post 13 is fixed to one end of the positioning plate 23.
[0061] The positioning column 13 is fixed to the surface of the support frame 2 and remains stable, thereby ensuring the stationary position of the side plate 11. The material can be smoothly moved down through the lower plate 21, upper plate 24 and bottom plate 12 of different heights.
[0062] Usage: The upper end of the vibrating plate 20 is fixedly connected to the inclined guide plate 45. When the inclined guide plate 45 vibrates, it drives the bottom plate 12, the lower plate 21 and the upper plate 24 to vibrate. The telescopic plate 19 deforms, and the positioning plate 23 is fixed on the surface of the positioning column 13. Then the side plate 11 remains stable. The bottom plate 12, the lower plate 21 and the upper plate 24 shorten the movement path to transport materials and avoid the adhesion of materials.
[0063] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.
[0064] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
