Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0018] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0019] like Figures 1-3 As shown, a two-material mixing ratio device is used for screening and mixing plastic granules. It includes a frame 1, with four lockable support guide wheels 11 installed at the bottom of the frame 1 to facilitate the movement of the device. A feeding hopper 2 is provided at the top of the frame 1. The feeding hopper 2 has a feeding cavity. A partition 3 is vertically arranged inside the feeding cavity, dividing the feeding cavity into two feeding chambers 23. The top of the feeding hopper 2 has two feeding openings 21 that connect the two feeding chambers 23. A door panel 24 that can be opened and closed is also hinged to one end of the top of the feeding hopper 2. A corresponding handle is also installed on the top of the door panel 24, which can be opened by the handle to inspect and clean the inside of the feeding hopper 2. An observation window 25 is provided on one side of the feeding hopper 2 below the door panel 24 for observing the internal condition of the feeding hopper 2.

[0020] An inclined screen 4 is installed inside the feed chamber 23. The inclined screen 4 is used to prevent large particles from passing through. The mesh opening of the inclined screen 4 can be changed according to the required particle size, which is practical. A screening hopper 10 is installed on the frame 1 on one side of the feed hopper 2. The screening hopper 10 is used to collect large particles (unqualified materials). The feed hopper 2 also has a screening through hole 26 in the inclined direction of the inclined screen 4. The screening through hole 26 is connected to the screening hopper 10 and the feed chamber 23. The bottom of the screening hopper 10 has a screening pipe 101. The screening pipe 101 is used to discharge large particles that fall in. The screening pipe 101 can be connected to an external collection device (not shown in the figure) through a connecting pipe. The top of the screening hopper 10 is hinged with a second cover plate 102 that can be opened and closed. The second cover plate 102 is also equipped with a corresponding handle. The second cover plate 102 can be opened by the handle, which is convenient for maintenance and cleaning inside the screening hopper 10.

[0021] The feed hopper 2 is provided with anti-blocking mechanisms 8 facing the inclined screen 4 on both sides of the two feed chambers 23. The anti-blocking mechanism 8 includes a V-shaped fixing plate 81, an anti-blocking fan 82 and an air outlet pipe 83. The V-shaped fixing plate 81 is provided on both sides of the feed hopper 2. The anti-blocking fan 82 is installed on the V-shaped fixing plate 81. The air outlet end of the anti-blocking fan 82 is connected to the air outlet pipe 83. The air outlet pipe 83 extends into the feed chamber 23 and faces the inclined screen 4. The anti-blocking fan 82 drives the air outlet pipe 83 to generate air pressure, which blows the inclined screen 4 to clear large particles of material that are blocked on the inclined screen 4, prevents large particles of material from accumulating and blocking, and ensures smooth feeding.

[0022] The bottom of the feed hopper 2 is provided with a conveying mechanism 5. The bottom of the feed hopper 2 has a discharge opening 22 that connects the feed chamber 23 and the conveying mechanism 5. The conveying mechanism 5 is provided with two conveying hoppers 51 at the bottom of the feed hopper 2. A mixing hopper 6 is provided on one side of each of the two conveying hoppers 51. A conveying pipe 52 that connects to the mixing hopper 6 is also provided on one side of each of the two conveying hoppers 51. A conveying motor 53 is provided on the other side of each of the two conveying hoppers 51. The rotating shaft of the conveying motor 53 is connected to a screw shaft 54. The screw shaft 54 ​​can rotate through the inner wall of the conveying pipe 52. The screw shaft 54 ​​is used to convey materials into the mixing hopper 6. The screw shaft 54 ​​is driven to rotate by the conveying motor 53, and the screw shaft 54 ​​can convey the material to the mixing hopper 6 through the conveying pipe 52 according to the set ratio.

[0023] The bottom of the conveying hopper 51 has threads, and a bottom cover 55 that can be opened and closed is connected by the threads. When it is necessary to replace or remove the material, or when the device is not in use, the material in the conveying hopper 51 can be discharged by unscrewing the bottom cover 55. At the same time, the conveying hopper 51 is connected to an externally adapted collection pipe by threads to transport the material to the material collection point.

[0024] The top of the mixing hopper 6 is also provided with a first cover plate 61 that can be opened and closed. The first cover plate 61 is used for the inspection and cleaning of the mixing hopper 6. The bottom of the mixing hopper 6 is connected to the discharge pipe 7. One end of the discharge pipe 7 has a discharge opening 71. The discharge pipe 7 is also provided with a vent hole 72. The size of the vent hole 72 is smaller than the size of the material particles, which can prevent the material from escaping from the vent hole 72. The discharge pipe 7 is connected to an external negative pressure device (not shown in the figure) or an external material use device (not shown in the figure). The external negative pressure device or the material use device generates negative pressure on the inner wall of the discharge pipe 7, thereby generating negative pressure in the mixing hopper 6, causing the material to move towards the discharge opening 71 of the discharge pipe 7 and be transported to the external material collection point or the external material use device.

[0025] The top of the frame 1 is also equipped with a control box 9, which is electrically connected to the anti-blocking fan 82 and the conveyor motor 53. The operation of this device is controlled through the control box 9, and the degree of automation is good.

[0026] Working principle: The device is moved to the working area by supporting guide wheels 11; In use, the two materials are added into the two feeding chambers 23 through the two feeding openings 21 respectively. The inclined screen 4 screens and blocks large particles. The qualified material that passes through the inclined screen 4 enters the conveying hopper 51 through the discharge opening 22. Since the inclined screen 4 is inclined towards the screening hole 26, large particles will enter the screening hopper 10 through the screening hole 26. When large particles clog the opening of the inclined screen 4, the control box 9 starts the anti-blocking fan 82. The anti-blocking fan 82 blows the inclined screen 4 with air pressure to prevent large particles from clogging the inclined screen 4. After the material falls into the conveying hopper 51, the conveying motor 53 is started by the control box 9. The conveying motor 53 drives the screw shaft 54 ​​to convey the material to the mixing hopper 6 according to the set ratio. After mixing, the material is driven out of the discharge pipe 7 by the external negative pressure device or the external material use device, and then conveyed to the external material collection point or the external material use device.

[0027] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
