Description

Technical Field

[0001] This utility model relates to the field of material handling equipment, and more specifically to a material particle sampling device. Background Technology

[0002] The processing of plastic granules involves shaping the plastic into granules of different sizes. The particle size range is typically between 0.1 mm and 5 mm. This range is determined by the manufacturing process, the requirements of the final product, and industry standards. For example, injection molding may require larger granules to ensure smooth mold filling, while film production may require finer granules to achieve a more uniform film thickness.

[0003] For the reasons mentioned above, it is necessary to screen the granulated plastic granules. In existing technologies, the granulated plastic granules are assumed to have a predetermined particle size and are used directly. However, due to the inherent elasticity of plastic, it is inevitable that some plastic granules will have a larger actual particle size than the preset size during the granulation process.

[0004] In fields requiring precise control, such as film production and fiber manufacturing, excessively large plastic particle sizes can lead to inconsistent film thickness and inconsistent particle size during production. Consequently, there is a lack of equipment on the market for screening plastic particles. Utility Model Content

[0005] In order to solve the above problems, the purpose of this utility model is to provide a material particle sampling device with simple structure, convenient maintenance, wide screening range and high screening efficiency.

[0006] According to one aspect of this utility model, a material particle sampling device is provided, comprising: a feeding hopper, a feeding pipe, a discharging component, and a screening component. The feeding pipe is located at the top of the feeding hopper and extends into the interior of the feeding hopper. An inlet door is located on the outer wall of the feeding hopper and communicates with the interior of the feeding hopper. The screening component is detachably installed inside the feeding hopper, and the discharging component is located at the bottom of the feeding hopper. The material to be granulated is introduced into the feeding hopper through the feeding pipe. The detachable screening component performs screening of particles of different sizes, and the discharging component separates the qualified particles.

[0007] In some embodiments, the screening assembly includes a wire mesh, a limiting block, and a material tray. The limiting block is annularly protruding from the inner wall of the feed hopper. The wire mesh is placed on top of the limiting block, and the material tray is placed below the wire mesh. The outer diameter of the wire mesh is smaller than the inner diameter of the feed hopper, and the outer diameter of the wire mesh is larger than the inner diameter of the limiting block. Different wire mesh apertures facilitate the separation of particles of different sizes, and the limiting block facilitates the detachable installation and removal of the wire mesh.

[0008] In some implementations, a fixing frame is fixedly connected around the perimeter of the wire mesh. The fixing frame helps to ensure the strength of the wire mesh.

[0009] In some embodiments, a first quick connector is provided at the top of the feed pipe, and the bottom of the feed pipe extends above the wire mesh. Extending the bottom of the feed pipe above the wire mesh ensures that the plastic particles are distributed on the wire mesh while maintaining screening efficiency.

[0010] In some embodiments, the discharge assembly includes a discharge section and a negative pressure section. The discharge section is connected to the bottom of the feed hopper and is located below the wire mesh. The negative pressure section is mounted on the discharge section. The cooperation between the negative pressure section and the discharge section facilitates the separation and extraction of the screened material particles.

[0011] In some embodiments, the discharge section includes a discharge pipe, a first valve, a second valve, and a second quick connector. One end of the discharge pipe is connected to the bottom of the feed hopper via the first valve, and the other end of the discharge pipe is provided with a second quick connector. A second valve is provided between the second quick connector and the discharge pipe. The discharge pipe and the second quick connector facilitate the introduction of the screened material into the collection device.

[0012] In some implementations, the discharge pipe is a bend.

[0013] In some embodiments, a negative pressure unit is installed at the bend of the discharge pipe. The negative pressure unit includes an air supply pipe, a third valve, and a third quick connector. One end of the air supply pipe is located at the bend of the discharge pipe, and the other end of the air supply pipe is equipped with the third quick connector. The third valve is located on the air supply pipe. By installing the air supply pipe at the bend, it is convenient to create negative pressure at the second quick connector to attract material particles.

[0014] In some embodiments, the top of the feeding hopper is provided with at least two sets of lifting lugs, and the bottom of the feeding hopper is provided with a support frame with rollers at the bottom. The lifting lugs facilitate the hoisting of this utility model, and the support frame facilitates the placement of this utility model.

[0015] This utility model discloses a material particle sampling device. The granulated material is introduced into the feeding hopper through a feeding pipe. A detachable screening component separates particles of different sizes, and a discharge component separates the qualified particles. Different mesh sizes facilitate the separation of particles of different sizes, and a limiting block allows for the detachable installation of the mesh. A fixing frame ensures the strength of the mesh. The bottom of the feeding pipe extends above the mesh, ensuring both the distribution of plastic particles on the mesh and the screening efficiency. The negative pressure and the discharge section facilitate the separation and extraction of the screened material particles. The discharge pipe and the second quick connector facilitate the introduction of the screened material into a collection device. Lifting lugs facilitate hoisting of the device, and a support frame facilitates its placement. Attached Figure Description

[0019] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings. However, it should be noted that these embodiments are not intended to limit the present invention. Equivalent transformations or substitutions in function, method or structure made by those skilled in the art based on these embodiments are all within the protection scope of the present invention.

[0020] In the description of this utility model, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "connection" should be interpreted broadly. For example, they can refer to mechanical or electrical connections, or internal connections between two components. They can be direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the terms according to the specific circumstances.

[0021] like Figure 1 As shown, the material particle sampling device of this utility model includes: a feeding hopper 1, a feeding pipe 2, a discharge assembly 3, and a screening assembly 4. The feeding pipe 2 is installed at the top of the feeding hopper 1 and extends into the interior of the feeding hopper 1. The outer wall of the feeding hopper 1 is provided with an inlet door 5, which communicates with the interior of the feeding hopper 1. The screening assembly 4 is detachably installed inside the feeding hopper 1, and the discharge assembly 3 is installed at the bottom of the feeding hopper 1. The material to be granulated is introduced into the feeding hopper 1 through the feeding pipe 2. The detachable screening assembly 4 is used to screen particles of different sizes, and the discharge assembly 3 separates the qualified particles.

[0022] like Figure 2 As shown, the screening component 4 includes: a wire mesh 41, a limiting block 42, and a material tray 43. The limiting block 42 is annularly protruding from the inner wall of the feed hopper 1. The wire mesh 41 is placed on top of the limiting block 42, and the material tray 43 is placed below the wire mesh 41. The outer diameter of the wire mesh 41 is smaller than the inner diameter of the feed hopper 1, and the outer diameter of the wire mesh 41 is larger than the inner diameter of the limiting block 42. The different aperture sizes of the wire mesh 41 facilitate the separation of particles of different sizes, and the limiting block 42 facilitates the detachable installation and removal of the wire mesh 41. The material tray 43 is used to scoop out larger particles from above the wire mesh 41 and place them back into the granulation equipment for granulation. The material tray 43 can be placed inside or outside the feed hopper 1.

[0023] like Figure 3 As shown, a fixing frame 44 is fixedly connected around the perimeter of the wire mesh 41. The fixing frame 44 helps to ensure the strength of the wire mesh 41.

[0024] A first quick connector 21 is provided at the top of the feed pipe 2, and the bottom of the feed pipe 2 extends above the wire mesh 41. This extension ensures that the plastic granules are distributed on the wire mesh 41 while maintaining screening efficiency. The granulated material is introduced into this invention for screening via the first quick connector 21 connected to a material granulation device. The distance between the bottom of the feed pipe 2 and the wire mesh 41 is two-thirds of the distance between the wire mesh 41 and the bottom of the feed hopper 1. This height ensures screening efficiency while allowing the material to be fully distributed on the wire mesh 41.

[0025] The discharge assembly 3 includes a discharge section 31 and a negative pressure section 32. The discharge section 31 is connected to the bottom of the feed hopper 1 and is located below the wire mesh 41. The negative pressure section 32 is installed on the discharge section 31. The cooperation between the negative pressure section and the discharge section 31 facilitates the separation and extraction of the screened material particles.

[0026] The discharge section 31 includes a discharge pipe 311, a first valve 312, a second valve 313, and a second quick connector 314. One end of the discharge pipe 311 is connected to the bottom of the feed hopper 1 through the first valve 312, and the other end of the discharge pipe 311 is provided with the second quick connector 314. The second valve 313 is provided between the second quick connector 314 and the discharge pipe 311. The discharge pipe 311 and the second quick connector 314 facilitate the introduction of the screened material into the collection device.

[0027] The discharge pipe 311 is a bent pipe.

[0028] The negative pressure unit 32 is installed at the bend of the discharge pipe 311. The negative pressure unit 32 includes an air supply pipe 321, a third valve 322, and a third quick connector 323. One end of the air supply pipe 321 is located at the bend of the discharge pipe 311, and the other end is connected to the third quick connector 323. The third valve 322 is mounted on the air supply pipe 321. By installing the air supply pipe 321 at the bend, a negative pressure is easily created at the second quick connector 314 to attract material particles. The third quick connector 323 is connected to a compressed air source.

[0029] By setting the discharge pipe 311 as a bend and setting one end of the air supply pipe 321 at the bend of the discharge pipe 311, a negative pressure is formed at the second valve 313 and the second quick connector 314 when blowing air. At the same time, the blown air will not move towards the first valve 312, thereby causing the air to blow towards the feed hopper 1, which causes the material particles to move downwards without hindrance.

[0030] The optimal bending angle at the bend of the discharge pipe 311 is 90°±5°. If the bending angle is too large, air will inevitably blow towards the first valve 312. If the bending angle is too small, although the above situation can be avoided, the material will be blocked at the bend and will not be easy to move. Therefore, the optimal bending angle is 90°.

[0031] The top of the feeding hopper 1 is provided with at least two sets of lifting lugs 6, and the bottom of the feeding hopper 1 is provided with a support frame 7. The lifting lugs 6 facilitate the hoisting of this utility model, and the support frame 7 facilitates the placement of this utility model. At the same time, for easy movement, rollers 8 are provided at the bottom of the support frame 7.

[0032] In the specific implementation process: First, quickly connect the first quick connector 21 to the discharge port of the granulation equipment, open the first valve 312, the second valve 313, and the third valve 322, and blow air through the equipment. A negative pressure is created at the second valve 313 and the second quick connector 314, drawing the material in the feed hopper 1 downwards for screening. After a period of screening, close the granulation equipment and the first valve 312, the second valve 313, and the third valve 322. Open the inlet door 5 and use the material tray 43 to scoop out the larger particles above the wire mesh 41 and place them back into the granulation equipment for granulation. Open the first valve 312, the second valve 313, and the third valve 322, and blow air through the equipment. A negative pressure is created at the second valve 313 and the second quick connector 314, drawing the material in the feed hopper 1 downwards for screening. Repeat the above steps.

[0033] The above descriptions are merely some embodiments of this utility model. It should be noted that those skilled in the art can make other modifications and improvements without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
