Description

Technical Field

[0001] The utility model relates to the technical field of blanking devices, in particular to a particle material blanking device. Background Art

[0002] Plastic pellets are the raw materials for plastic product processing (such as PVC pipes). During processing, the raw materials (i.e., plastic pellets) are generally introduced into the processing equipment through a feed hopper. The feed hopper in the existing technology is generally a large-top, small-bottom structure, with the small bottom part connected to the feed port of the equipment and the large top part for the raw materials to enter. During the actual feeding process, the raw materials may contain irregular parts such as plastic strips and plastic blocks that have not been formed into granules. Although these are also plastic components and may not affect subsequent processing, they can easily cause blockage at the lower end of the feed hopper. Therefore, before feeding into the feed hopper, it is generally necessary to perform a screening to screen out the irregular parts. This increases the overall processing time and reduces the overall efficiency. Utility Model Content

[0003] In view of the deficiencies in the prior art, the present invention provides a granular material feeding device, which solves the problem in the prior art that irregular raw materials are first screened, resulting in reduced overall processing efficiency.

[0004] According to an embodiment of the present invention, a device for discharging particulate material includes:

[0005] The feed hopper has a feed guide tube fixedly connected to its upper end;

[0006] The support frame includes a guide hopper abutting against the inner wall of the lower end of the guide barrel, a plurality of support rods fixedly connected to the guide hopper and extending obliquely upward, and a lower mounting plate fixedly connected to the higher ends of all the support rods;

[0007] The material distribution plate is located at the lower end of the feed hopper and is fixedly connected to a drive shaft at the center. The drive shaft extends upward and rotates through the lower mounting plate. A first drive motor connected to the drive shaft is also installed on the lower mounting plate. A plurality of first through holes are also provided on the material distribution plate.

[0008] In the above embodiment, the upper guide barrel allows the raw materials to enter, and then passes downward through the support rod and falls into the distribution plate through the guide hopper. The first through hole on the distribution plate allows normal raw materials to pass through, and the irregular ones are intercepted in the distribution plate. This prevents the irregular parts from continuing to fall downward and will not enter the lower end of the feed hopper, avoiding blockage at the feed hopper outlet, and solving the problem in the prior art of first screening the irregular raw materials, resulting in reduced overall processing efficiency.

[0009] Furthermore, the outer edge of the distribution plate is higher than its center, and a collar is fixedly connected to the outer edge. A support ring is also fixedly connected to the inner wall of the feed hopper, and the collar can be in sliding contact with the support ring.

[0010] Furthermore, a vertical cylinder is fixedly connected between the outer edge of the distribution plate and the mounting ring, and a plurality of second through holes are provided on the vertical cylinder.

[0011] Furthermore, an extension frame extending above the material guide cylinder is fixedly connected to the lower mounting plate, and the first drive motor is mounted on the extension frame.

[0012] Furthermore, the lower end surface of the guide hopper has an orthographic projection located within the distribution tray.

[0013] Furthermore, the lower mounting plate is also fixedly connected to a rotating sleeve which is arranged outside the driving shaft.

[0014] Furthermore, a fixing sleeve is fixedly connected to the inside of the distribution tray and is arranged outside the driving shaft.

[0015] Furthermore, the first drive motor is also fixedly connected to a ring plate, and the ring plate is fixed to the extension frame by bolts.

[0016] Furthermore, the lower end of the feed hopper is also connected to a conveying pipe, which extends horizontally and has a second drive motor installed at one end. A conveying screw connected to the second drive motor is also rotatably arranged in the conveying pipe, and a discharge port is provided at the end of the conveying pipe away from the second drive motor.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] After the raw materials enter the feed hopper, they are first screened by the dividing plate, and the irregular parts are intercepted in the dividing plate, which prevents the irregular parts from continuing to fall downward and entering the lower end of the feed hopper, avoiding blockage at the feed hopper outlet, and solving the problem of reducing the overall processing efficiency by screening the irregular raw materials first in the existing technology.

[0028] In an exemplary embodiment, Figure 1-3 As shown, this embodiment provides a device for discharging particulate materials, which includes:

[0029] A feed hopper 1, the upper end of which is fixedly connected to a material guide cylinder 2 with a larger upper portion and a smaller lower portion;

[0030] The support frame includes a guide hopper 3 abutting against the inner wall of the lower end of the guide barrel 2, a plurality of support rods 4 fixedly connected to the guide hopper 3 and extending obliquely upward, and a lower mounting plate 5 fixedly connected to the higher ends of all the support rods 4;

[0031] The distribution plate 6 is located at the lower end of the feed hopper 1 and is fixedly connected to a drive shaft 7 at the center. The drive shaft 7 extends upward and rotates through the lower mounting plate 5. The lower mounting plate 5 is also equipped with a first drive motor 8 connected to the drive shaft 7. The distribution plate 6 is also provided with a plurality of first through holes 9.

[0032] In the above embodiment, the upper guide barrel 2 is used for the raw material to enter, and then it passes downward through the support rod 4 and falls into the distribution plate 6 through the guide hopper 3. The first through hole 9 on the distribution plate 6 is used for normal raw materials to pass through, and the irregular ones are intercepted in the distribution plate 6. This prevents the irregular parts from continuing to fall downward and will not enter the lower end of the feed hopper 1, thereby avoiding blockage at the outlet of the feed hopper 1, and solves the problem of the prior art that the irregular raw materials are screened first, resulting in reduced overall processing efficiency; after the raw materials enter the feed hopper 1, the first drive motor 8 drives the drive shaft 7 to rotate, thereby making the distribution plate 6 in a rotating state, so that the screening efficiency is improved. In more detail, the outer edge of the distribution plate 6 is higher than its center, and its outer edge is also fixedly connected to a ring 10, so that the feed A support ring 11 is also fixedly connected to the inner wall of the hopper 1 and the mounting ring 10 can slide in contact with the support ring 11, so that the material distribution plate 6 and the mounting ring 10 are equivalent to dividing the feed hopper 1 into two parts, upper and lower, so that all the raw materials are screened, and the mounting ring 10 is supported by the support ring 11, which also enables the material distribution plate 6 to rotate more smoothly under the drive of the first drive motor 8. More importantly, the support frame in this solution can lift the feed hopper 1 upward as a whole, which is convenient for cleaning the intercepted part in the material distribution plate 6; in particular, the support frame and the first drive motor 8 have a large weight, and are obliquely pressed on the inner wall of the lower end of the guide cylinder 2 through the guide hopper 3, and can be relatively fixed, so that the first drive motor 8 can smoothly drive the drive shaft 7 to rotate when it is running.

[0033] like Figure 1 、 4 As shown, in a more detailed scheme, the lower mounting plate 5 is also fixedly connected to an extension frame 12 extending above the material guide barrel 2, and the top of the extension frame 12 is also fixedly connected to an upper mounting plate 13, and the first drive motor 8 is mounted on the upper mounting plate 13 on the extension frame 12. The extension frame 12 allows the first drive motor 8 to be completely located above to avoid affecting the entry of raw materials. In more detail, the lower mounting plate 5 is also fixedly connected to a rotating sleeve 14, which is arranged on the outside of the drive shaft 7, so that the rotating sleeve 14 can provide rotation support for the drive shaft 7 in the middle section, so that the drive shaft 7 rotates more smoothly. More specifically, the first drive motor 8 is also fixedly connected to a ring plate 15, which can be fixed to the upper mounting plate 13 on the extension frame 12 by bolts, thereby realizing the relative fixation of the first drive motor 8 and the support frame and the extension frame 12, and being taken out together when taken out.

[0034] like Figure 1 、 3As shown in Figure 5, a vertical cylinder 16 is fixedly connected between the outer edge of the distribution plate 6 and the ring 10, and a plurality of second through holes 17 are provided on the vertical cylinder 16. The first through hole 9 and the second through hole 17 can be long strips or circular. The width or diameter is larger than the particle size of the raw material to ensure that the raw material passes through smoothly. In more detail, the lower end face of the guide hopper 3 has a positive projection located in the distribution plate 6, so as to ensure that the raw material enters the distribution plate 6 smoothly for screening.

[0035] like Figure 5 As shown, a fixing sleeve 18 is fixedly connected to the inside of the distribution tray 6 and is arranged outside the driving shaft 7, thereby achieving a fixed connection between the distribution tray 6 and the driving shaft 7.

[0036] like Figure 1 As shown, the lower end of the feed hopper 1 is also connected to a conveying pipe 19, which extends horizontally and has a second drive motor 20 installed at one end. A conveying screw 21 connected to the second drive motor 20 is also rotatably provided in the conveying pipe 19, and a discharge port 22 is provided at the end of the conveying pipe 19 facing away from the second drive motor 20. The discharge port 22 is connected to the feed port of the processing equipment, so that the conveying screw 21 is driven to rotate by the second drive motor 20, so that the raw materials can be fed more smoothly under the push of the conveying screw 21.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
