[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

They are not intended to indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "provided with," "connected," etc. should be understood in a broad sense. For example, "connected" can mean a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be internal communication between two components. Those skilled in the art will be able to understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0025] like Figures 1-4As shown, a discharging device for processing water-based polyurethane resin includes a tank body 1, and mounting frames 2 are installed on the front and rear parts of the outer surface of the tank body 1. A discharge pipe 3 is inserted and connected to the lower end of the tank body 1. A U-shaped plate 4 is fixedly sleeved on the lower part of the outer cylindrical surface of the discharge pipe 3. The lower end of the discharge pipe 3 extends to the upper inner wall of the U-shaped plate 4. When in use, the powdered raw material for processing the water-based polyurethane resin is placed in the tank body 1 and discharged into the processing equipment through the discharge pipe 3. However, quantitative loading cannot be performed, and the inability to quantitatively load the material will lead to uneven supply of raw materials, and there may be too much or too little raw materials.

[0026] In order to solve the above-mentioned disadvantages, a horizontal plate 5 is connected to the rear end of the front mounting frame 2, and the upper end of the horizontal plate 5 is movably in contact with the first quantitative column 74. The upper end of the first quantitative column 74 is movably in contact with the upper end of the discharge pipe 3. A slide plate 73 is fixedly sleeved on the upper part of the outer cylindrical surface of the first quantitative column 74. When in use, the horizontal plate 5 is placed above the feeding port of the processing device, and the raw material falls into the first quantitative column 74 through the discharge pipe 3. After the first quantitative column 74 is full, the slide plate 73 is driven to move to the right, and the slide plate 73 drives the first quantitative column 74 to move to the right. When moving, the slide plate 73 blocks the discharge pipe 3 and prevents the raw material from continuing to fall. When the first quantitative column 74 moves to the edge of the horizontal plate 5, all the raw materials in the first quantitative column 74 are discharged. The same steps are repeated before, and quantitative loading can be performed each time to ensure uniform supply of raw materials, avoid excessive or insufficient raw materials, and ensure the stability of the production process and the quality consistency of the final product.

[0027] In order to drive the automatic movement of the slide plate 73, an electric cylinder 71 is installed at the upper end of the U-shaped plate 4. The output end of the electric cylinder 71 is fixedly connected to the connecting plate 72. The lower end of the connecting plate 72 is fixedly connected to the lower end of the slide plate 73. The front and rear ends of the slide plate 73 are both in active contact with the inner wall surface of the U-shaped plate 4.

[0028] A telescopic cover 6 is installed at the right end of the transverse plate 5, and the telescopic cover 6 is used to guide the falling raw materials into the processing device.

[0029] In addition, in order to adapt to the raw material requirements of different production processes and realize flexible production, it is necessary to adjust the quantitative capacity. For this reason, the outer surface of the first quantitative column 74 is movably sleeved with a second quantitative column 8, and the lower portion of the outer surface of the second quantitative column 8 is fixedly sleeved with a ring 9. The ring 9 is used to prevent the second quantitative column 8 from separating from the transverse plate 5. The lower ends of the second quantitative column 8 and the ring 9 are both movably in contact with the upper end of the transverse plate 5. The transverse plate 5 is slidably connected to the front mounting frame 2. The rear end of the transverse plate 5 is fixedly connected to the first L-shaped plate 10. The first L-shaped plate 10 is slidably connected to the rear mounting frame 2. The internal movable sleeve of the first L-shaped plate 10 is provided with two guide rods 13. The upper ends of the two guide rods 13 are jointly installed with the second L-shaped plate 11. The second L-shaped plate 11 is fixedly connected to the U-shaped plate 4, and the second L-shaped plate 11 and the first L-shaped plate 10 have a common internal thread sleeve with a screw rod 12, which is driven by a driving device or manually driven to rotate, and the upper and lower ends of the screw rod 12 extend to the upper side of the second L-shaped plate 11 and the lower side of the first L-shaped plate 10 respectively. When it is necessary to increase the amount of material loaded, the screw rod 12 is driven to rotate, and the screw rod 12 drives the first L-shaped plate 10 to move downward, and the first L-shaped plate 10 drives the cross plate 5 to move downward, and the cross plate 5 drives the second quantitative column 8 to move downward, so that the raw material can enter the second quantitative column 8, which can increase the loading capacity, adapt to the raw material requirements of different production processes, realize flexible production, and is suitable for products of various specifications or batches.

[0030] The outer surface of the first quantitative column 74 is provided with scale lines 741 , through which the volume of the increased capacity can be observed.

[0031] On the basis of the above scheme, in order to ensure that the raw materials can fall smoothly, a support frame 14 is installed at the upper end of the tank body 1. The internal movable sleeve of the support frame 14 is provided with a rotatable screw rod 15. The screw rod 15 extends into the discharge pipe 3. The screw rod 15 can be driven by a motor to drive the screw rod 15 to rotate. The screw rod 15 can drive the raw materials blocked in the discharge pipe 3 to fall.

[0032] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention.
